    [0001] [001] The present invention relates to a lanyard fixing device and, in particular, to a lanyard fixing device that is able to improve convenience when in use and productivity and durability of a product, once the configuration and operation are simplified. TECHNICAL HISTORY
    [0002] [002] Generally speaking, a cord fixing device is being applied for several purposes and is used to fix items. Here, among several applications for the lanyard fixation device, the application in which this lanyard fixation device is used for sneakers on the feet will be described mainly, but it is obvious that this lanyard fixation device can be applied to sneakers, as well such as various items, for example, a hair decoration item, including a cap, a belt, gloves, a bag, a snowboard, water ski etc. that can be used using a lanyard.
    [0003] [003] However, shoes, for example, sneakers, include cords that are intended to be connected in a zigzag manner, so that the shoes can be the shoes that best fit the user. The fit between the user's shoes and feet can be improved by tightening the laces, so that the user can walk more comfortably.
    [0004] [004] In fact, an appropriate shoe size must be selected, otherwise, the shoes may come off during walking. It is common for the user to put the shoes on with the laces being tied a little loosely to put on or take off more easily, but for the health of the feet, the laces are preferably tightened to the extent that the shoes do not tighten the shoes during walking , thus, making sure that the shoes do not become loose.
    [0005] [005] However, it is uncomfortable to tighten or loosen the laces whenever the user puts on or takes off the shoes, so that the user wears the shoes with the laces being tied a little loose, except for special occasions. In this case, the user must stop walking if the strings are untied to tie the strings again, which causes a lot of annoyance. If both ends of the laces are not attached, although the laces are not untied, the shoes may appear unattractive.
    [0006] [006] Furthermore, it is not easy for students of younger years or children before school age or elderly men and women to tighten or loosen cords, and athletes or ordinary people who are going up or down a mountain and are bicycle runners may have records bad or can suffer accidents if both ends or knots of the unfixed cords are untied due to violent actions when the cords get caught in anything outside, so it is preferred to keep the untying place of the cords fixedly.
    [0007] [007] Furthermore, it is more preferred that the strings should be tied easily, as it is possible to have enough peace of mind in the event that the strings are loosened during rest and the strings should be kept stable, and the tight strings should be loosened easily.
    [0008] [008] Developments for a lanyard tightening device are underway, which provides a function in helping to tighten and untie the laces, the actions of which are contrary.
    [0009] [009] For example, the typical cord clamping device is implemented in such a way as to use a ratchet type gear and is configured, so that an internal rotation member, having a spool part, around which the cords are coiled, can be selectively restricted. Here, if the rotating member rotates in one direction, it can be activated to tighten the cords, and if the ratchet gear is released through a latch, the spool part rotates independently, thus untying the cords .
    [0010] [010] However, according to the conventional lanyard tightening device, the laces must be loosened so that the latch is pushed aside with one hand, in order to release the ratchet gear and then the laces must be unscrewed with the other hand. In that case, since both hands are inevitably used, it is inconvenient to use, and children or weak people, who cannot easily learn how to use, may find it difficult to use this device.
    [0011] [011] In addition, according to the lanyard clamping device above, if the latch is not pushed properly to one side, the loosening procedure can be interrupted, for example, the laces can become trapped in something, while the strings are being pulled and untied. For this reason, product reliability can become poor. In addition, if a separate locking device is additionally provided, in order to fix a state in which the lock is pushed aside, the entire configuration can be complicated, thereby increasing the number of components, while reducing productivity. DISCLOSURE OF THE INVENTION TECHNICAL PROBLEM
    [0012] [012] Accordingly, an objective of the present invention is to provide a cord clamping device that is able to improve convenience when in use, thanks to the simplified configuration and operation, and productivity and durability of the products can be improved. SOLUTION TO THE PROBLEM
    [0013] [013] In order to solve the above objective, a cord fixing device is provided including a carcass part provided with a ratchet type gear in its internal circumference and having a cylindrical internal surface; a spool part axially coupled to the inside of the carcass part and arranged in a rotating manner, so that a cord is wound, and having a ratchet-type protrusion is formed in its upper part; a lifting cam part having a sliding protrusion, which is coupled in a selectively elevating manner along the ratchet-type protrusion, formed at its bottom, an outer circumferential cam groove part formed at its outer circumference, and a part internal circumferential cam groove formed in its internal circumference; a cam drive unit in which a cam protruding part, which is coupled to the inner circumferential cam groove part, in order to raise the lift cam part during unidirectional rotation, is formed; a cam base part having a guiding cam part, which is inserted into the outer circumferential cam groove part, in order to guide the elevation of the lifting cam part, formed in its inner circumference and having a coupling part ratchet, whose unidirectional rotation is restricted by the ratchet type gear, provided in its external circumference; and a revolving cover coupled to the top of the cam drive unit, so that it can be rotated in an integral manner.
    [0014] [014] Here, the inner circumferential cam groove part and the cam protrusion part are obliquely formed to ascend when rotating in one direction, so that the lift cam part ascends and the ratchet-type protrusion of the the spool part separates from the sliding protrusion when the cam drive unit rotates in one direction, and the outer circumferential cam groove part and the guide cam part are formed obliquely in the opposite direction to the inclined directions of the internal circumferential cam groove and the protruding cam part.
    [0015] [015] In addition, the ratchet-type protrusion is formed of a plurality of protrusions, each having an inclined surface that ascends in a direction along the circumferential direction on the upper surface of the spool part, and the slide protrusion is formed , corresponding in form with the ratchet-type protrusion, and the rotation in one direction of the spool part is restricted when contacting the vertical surface, and the rotation in the other direction slides along the inclined surface and separates.
    [0016] [016] In addition, an external circumferential unit that is spaced from the ratchet coupling part to the outside and is swiveled, covering the rim of the top of the housing part, is connected to an external circumference of the cam base part, and a latch groove part open at an established rotation angle is formed in the outer circumferential unit, and a latch protrusion that is inserted into the latch groove part and restricts the rotation angle is formed in an inner circumference of the revolving cover .
    [0017] [017] However, the swivel cover includes a magnetic hitch unit, and a logo mark made of ferromagnetic metal is affixed and unsnapped selectively from an outer surface of the top of the swivel cover. EFFECTS OF THE INVENTION
    [0018] [018] The cord clamping device of the present invention can provide the following effects, thanks to the solutions above.
    [0019] [019] First, the lanyard clamping device can tighten or release a lanyard by rotating a swivel cover that is fully engaged and affixed to the lanyard in one direction or the other, so operation is simple and convenient when in use , can be improved, and the tightening and release can be precisely adjusted according to the direction of rotation, so any inconvenience caused possibly due to errors during operation can be removed, and the reliability of the product can be improved.
    [0020] [020] Secondly, in the cord clamping device, since a sliding protrusion and a ratchet-type protrusion of a spool part can be disengaged or engaged based on the raising or lowering of a lifting cam part, according to the direction of rotation of the revolving cover, thus, the spool part can be selectively restricted, so that the convenience, when in use, can be greatly improved, since the spool part can escape from the cam part lift and rotate independently, thus extracting and releasing the cord with the help of rotations in one direction or the other direction, without operating the swivel cover up or down.
    [0021] [021] Third call, since the locking protrusion of the rotating cover is restricted by a locking groove part of the cam base part, when the user's torque exceeds the rotation angle necessary for fitting or disengaging on the spool part, it is over-transferred, the internal components can be protected from being broken, thus, the durability of the product can be improved.
    [0022] [022] In fourth call, the lanyard fixing device is equipped with a magnetic coupling unit that is able to easily affix or unpin a ferromagnetic logo mark using magnetic force, thus it is possible to easily affix or unpin a logo mark that a user or manufacturer prefers. Aesthetic efficiency in terms of product design and an advertising effect can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

    [0030] [030] The best mode of the present invention will be given in detail below with reference to the accompanying drawings. MODES FOR CARRYING OUT THE INVENTION
    [0031] [031] The cord clamping device, according to a preferred embodiment of the present invention, is described below, referring to the accompanying drawings.
    [0032] [032] FIGURE IA is a perspective view showing a shoe to which a lanyard fixing device has been applied, in accordance with an embodiment of the present invention. FIGURE 1B is a perspective view showing a cap to which a cord fastening device has been applied, in accordance with an embodiment of the present invention. Here, the lanyard clamping device 100 can be applied to a device installed in shoes or a cap to help use, as well as a clamping device that can be used in a variety of ways for an item, for example, clothing, accessories, exercise tools, etc., which can be used by tightening a cord or string like a belt, gloves, a bag, a water ski or snowboard etc.
    [0033] [033] As pictured in FIGURES IA to 1B, the cord fixing device 100 can be used in order to tighten a shoe cord "w" or a cap. In the case of shoes, it is preferred that the lanyard fixing device 100 is affixed to an upper surface of a part of the tongue to which the lanyard "w" is attached. Can be attached to a side of the shoe considering the design etc.
    [0034] [034] At that moment, as the swivel cover of the cord clamping device 100 rotates, the cord "w" can be rolled up and tightened. For this reason, the cord clamping device 100 can properly tighten the cord "w" in relation to size, including the width and height of the user's foot, thus the user can walk in a comfortable manner.
    [0035] [035] In addition, in the case of the cap, it can be attached to a side surface to which the "w" cord is connected. It can be affixed to a rear side of the cap, considering the convenience when in use and improvements in terms of design. In addition, in the case in which it is applied to the mountaineering cap or a military helmet, it can be attached to a string that runs below a user's jaw.
    [0036] [036] As mentioned earlier, the cord can be tightened properly in relation to size, including around a user's ear and the length from top to bottom, which can consequently lead to stable use. Therefore, it is possible to prevent any blockage of the user's view and any interference with a user's activity if a cap falls or is turned over, due to an environmental reason, for example, rain or wind or an external force during the user's activity. .
    [0037] [037] FIGURE 2A is a disassembled perspective view, when viewed in the upward direction, of a cord fastening device, in accordance with an embodiment of the present invention. FIGURE 2B is a disassembled perspective view, when viewed in the downward direction, of a cord fastening device, in accordance with an embodiment of the present invention. FIGURE 3 is a vertical cross-sectional view depicting an engaged configuration of a cord clamping device, in accordance with an embodiment of the present invention.
    [0038] [038] As pictured in FIGURES 2A to 2B, the cord clamping device 100 may include a housing part 60, a spool part 40, a lift cam part 30, a cam drive unit 20, a part cam base 50, a swivel cover 10, a swivel shaft 70 and a locking screw 80.
    [0039] [039] Here, a ratchet-type gear 62 is provided on an upper side of an internal circumferential surface of the housing part 60. A lower surface of the housing part 60 is attached to an outer layer of a shoe. The carcass part 60 may have a cylindrical internal space to accommodate the spool part 40. The cam base part 50 is provided in a rim of the top of the carcass part 60.
    [0040] [040] At this time, the cam base part 50 is pivotally connected to a rim of the top of the carcass part 60, however, it is preferred that the counterclockwise rotation is restricted by the ratchet type 62 gear .
    [0041] [041] In addition, the lift cam part 30 is accommodated on the inner circumference of the cam base part 50. Here, the lift cam part 30 rises and falls in the direction of rotation of the cam drive unit 20, thus, selectively engaging with the upper surface of the spool part 40. In addition, the cam drive unit 20 can be provided on top of the cam base part 50, but it is preferred that a protrusion unit is formed in the drive unit 20 and is fitted to an internal circumference of the lifting cam part 30.
    [0042] [042] In addition, the swivel cover 10 is fitted to the top of the cam drive unit 20 and rotates integrally, and it is preferred that the rim on the underside of the swivel cover 10 is fitted to the cam base part 50 .
    [0043] [043] At this time, the locking screw 80 is fitted through the swivel cover 10 and the swivel shaft 70 and the housing part 60. In addition, the swivel shaft 70 passes through the spool part 40, the base part of the cam 50, the lifting cam part 30 and the cam drive unit and is arranged as surrounding the locking screw 80.
    [0044] [044] Therefore, the engaged configuration of the internal components that form the cord clamping device 100 can be maintained by means of the plug-in screw 80. In addition, the rotary shaft 70 performs a function of a bearing between the components and the screw so that internal components can be swiveled, while preventing abrasion and improving durability.
    [0045] [045] In addition, on the cord clamping device 100, when the rotating cover 10 rotates in a clockwise direction, the lifting cam part 30 descends and is attached to the spool part 40 and rotates integrally and drives to roll up the "w" cord. When rotating counterclockwise, the lifting cam part 30 rises, and the spool part 40 rotates independently, thus extracting and releasing the "w" cord ...
    [0046] [046] In fact, the direction of rotation of the swivel cover to direct the cord to be wound is not limited to the clockwise direction. The direction of rotation can be adjusted to the opposite direction, by changing the setting of the lanyard fixture.
    [0047] [047] However, the housing part 60 accommodates the ratchet type gear 62, a rotary shaft socket unit 69, a draw-through hole 65, and a spool socket unit 64. At that time, in order to If the user efficiently applies the rotation force to the revolving cover 10, it is preferred that the lower surface of the housing part 60 is fixed in a part in which the cord fixing device is fitted, for example, in an external layer of a shoe or a fastening part of a cap.
    [0048] [048] In addition, the carcass part 6 is formed cylindrical, and a bore through hole 65 is formed on its underside for the bead to pass. Inside the underside of the housing part 60, the spool insert unit 64 is formed, so that the spool part 40 is engaged and can rotate. It is preferred that the spool fitting unit 64 is formed in the form of a cylindrical space to prevent any friction, due to the rotations of the spool part.
    [0049] [049] In addition, the ratchet-type gear 62 is provided on an internal circumference of the top rim of the housing part 60 and is swiveled to the outer circumference unit 59 of the cam base part 50 and limits the rotations in the counterclockwise direction of the cam base part 50.
    [0050] [050] For this reason, in the housing part 60, the counterclockwise rotations can be limited when a state to extract and release the cord, as the user rotates the revolving cover 10 of the device in a counterclockwise direction. lanyard fastening 100, is satisfied, thus, the release status of the lanyard can be observed. Therefore, it is possible to improve any inconvenience, when in use, since inconvenience due to errors during operation can be removed.
    [0051] [051] In addition, the housing part 60 plays a role in the event that the internal components of the cord clamping device 100 can be activated, thus preventing the components from being lost, which makes it possible to improve the durability of the products.
    [0052] [052] In fact, a detachable adhesive member, for example, a double-sided tape, can be provided on the bottom surface of the carcass part 60. For this reason, a fixing force can be improved by fixing on the outer layer of the shoe thus, the cord can be wound in a stable manner. When the lanyard is released, independent rotations of the spool part can be supported in a stable manner, so that the convenience, when in use, of the lanyard fixing device can be further enhanced.
    [0053] [053] Meanwhile, the spool part 40 includes a ratchet-type protrusion 43, a cord winding unit 42, a cord tie-up hole 44, and a swivel shaft through hole 49. Here, the spool part 40 is fitted to a lower inner side of the housing part 60 by means of the pivot axis and is pivotally arranged. The cam base part 50 is arranged on top of the spool part 40. Here, it is possible to selectively fit the ratchet-type protrusions 43 formed on the underside of the lift cam part 30 fitted to the inner circumference of the cam base part 50 and on the upper surface of the spool part 40.
    [0054] [054] Furthermore, it is preferred that the ratchet-type protrusion 43 is formed by protruding upwards in a counterclockwise direction along a circumference of the upper surface of the spool part and is selectively fitted to a sliding protrusion 33 formed on the underside of the lifting cam part 30. Here, the ratchet-type protrusion 43 and the slide protrusion 33 are engaged or disengaged based on the direction of rotation of the cam drive unit 20.
    [0055] [055] Namely, if the lifting cam part 30 descends as the cam drive unit 20 rotates clockwise, the vertical surface of the slide protrusion 33 having an inclined surface that protrudes downwards along the circumferential direction and the vertical surface of the ratchet-type protrusion 43 meet, so that the torque can be transferred efficiently.
    [0056] [056] In addition, if the lifting cam part 30 rises as the cam drive unit 20 rotates counterclockwise, the slide protrusion 33 can gently separate along the inclined surface of the ratchet-type protrusion 43 .
    [0057] [057] For this reason, the tightening and releasing states of the lanyard clamping device 100 can be changed smoothly, thereby improving convenience when in use, and flexibility can be provided in the configuration of the lanyard clamping device. 100, thus improving durability and improving product reliability.
    [0058] [058] In addition, the cord winding unit 42 is formed in a form of concave grooves along the circumferential direction on the rim surface of the spool part 40 so that the cord is wound. Here, it is preferred that the cord passes through the side of the carcass part 60 and exposes itself to the outside, thereby tightening or releasing the shoes.
    [0059] [059] At that time, the cord tie-down hole 44 is formed in the spool part 40. It is preferred that the cord inserted inwardly through the carcass part 60 is wound around the spool part 40 through the tie down hole of drawstring 44. For this reason, drawstring clamping device 100 can prevent unnecessary rotation of the spool part 40, thus the torque can be transferred efficiently, thereby improving convenience when in use.
    [0060] [060] Meanwhile, the lift cam part 30 includes an inner circumferential cam groove part 32, an outer circumferential cam groove part 31, and a slide protrusion 33. Here, the lift cam part 30 is arranged covering the pivot shaft connection unit 22 formed on the cam drive unit 20 and is fitted to the cam protrusion part 22a of the cam drive unit 20 via the inner circumferential cam groove part 32. In addition, it is attached to the guiding cam part 51 by means of the outer circumferential cam groove part 31, but is preferably arranged within the cam base part 50 to ascend or descend upwards or downwards.
    [0061] [061] At that time, the lifting cam part 30 ascends or descends along the direction of rotation of the cam drive unit 20, thus, the slide protrusion 33 formed on the lower surface of the lifting cam part 30 can be engaged selectively to the ratchet-type protrusion 43 formed on the upper surface of the spool part 40.
    [0062] [062] In addition, the inner circumferential cam groove part 32 is formed by covering the outer surface of the cam protrusion part 22a, but is preferably formed in the same inclined direction, so that it can correspond to the shape of the outer profile of the part cam protrusion 22a while surrounding it. In addition, the outer circumferential cam groove part 31 is arranged to its inner surface to fit the outer surface of the guide cam part 51, but is preferably formed in the same inclined direction, so that it can correspond to the shape of the profile outer part of the guide cam 51.
    [0063] [063] At that time, the outer circumferential cam groove part 31 and the guide cam portion 51 preferably have the inclined types that are opposed to the inner circumferential cam groove part 32 and the cam protrusion part 22a.
    [0064] [064] In more detail, the cam protrusion part 22a is formed in an inclined shape to ascend circumferentially in a clockwise direction along an outer circumferential surface of the rotary shaft connection unit 22, and the groove part inner circumferential cam 32 is formed in an inclined shape to ascend circumferentially in a clockwise direction along an inner circumferential surface of the lifting cam portion 30.
    [0065] [065] In addition, the guide cam part 51 is formed in an inclined shape to descend in a clockwise circumferential direction along the inner circumferential surface of the cam base part 50, and the circumferential cam groove part outer 31 is formed in an inclined shape to descend circumferentially in a clockwise direction along an outer circumferential surface of the lifting cam part 30.
    [0066] [066] Thus, the lifting cam part 30 can move up and down, since the outer circumferential cam groove part 31 slides based on the orientation of the guide cam part 51 by the torque transferred from the part protrusion 22a to the inner circumferential cam groove part 32.
    [0067] [067] Therefore, the cord clamping device 100 can perform the operations to release or tighten the cord by adjusting the engaged state of the lifting cam part 30 and the spool part 40 when using only the rotations in one direction or in the another direction. Therefore, the convenience, when in use, can be improved, since the inconvenience that occurs due to the need to release the cord can be removed with the help of independent rotations of the spool part, by pulling the revolving cover up and down 10 .
    [0068] [068] In addition, the slide protrusion 33 is formed on the lower surface of the lifting cam part 30, and can be selectively attached to the ratchet-type protrusion 43 formed on the upper surface of the spool part 40 by means of the ascending operations and lowering the lifting cam part 30.
    [0069] [069] Here, the ratchet-type protrusion 43 is made in the form of a plurality of protrusions that each have an inclined surface that rises in a counterclockwise direction along the circumferential direction and is formed on the upper surface of the spool part 40, and the slide protrusion 33 is fitted to the ratchet type protrusion 43, while corresponding in shape. Namely, the slide protrusion 33 has an inclined surface that protrudes downwards in a clockwise direction along the circumferential surface and is formed on the lower surface of the lifting cam part 30.
    [0070] [070] Therefore, if the lifting cam part 30 descends by turning clockwise, the vertical surface of the slide protrusion 33 contacts the vertical surface of the ratchet type protrusion 43, thus efficiently transferring the torque of the lift cam 30 for the spool part 40, while, if the lift cam part 30 ascends by turning counterclockwise, the inclined surface of the slide protrusion 33 may slide along the inclined surface of the ratchet-type protrusion 43 thus, the lifting cam part 30 can smoothly separate from the spool part 40.
    [0071] [071] Therefore, since it is possible to flexibly change the tightening and releasing states of the cord clamping device 100, the convenience, when in use, can be improved in an efficient manner. In order to prevent any abrasion when the slide protrusion 33 in the released state separates from the ratchet type protrusion 43, the present invention allows to improve the durability of the cord clamping device 100, while improving the reliability of the products.
    [0072] [072] Meanwhile, the cam drive unit 20 includes a restraining protrusion 21, a supporting member 24, a supporting protruding fitting lip 23, a pressing protrusion 25, and a rotating shaft connection unit 22 in which the cam protrusion part 22a is formed. Here, it is preferred that the cam drive unit 20 is attached to the revolving cover 10 and rotates integrally. At that time, the restriction protrusion 21 formed on top of the cam drive unit 10 is fixedly inserted into the restriction groove part 11 of the swivel cover 10.
    [0073] [073] In addition, a support protrusion fitting lip 23 formed on one side of the cam drive unit rim 20 strictly contacts the support protrusion 13 formed on the rotating cover, thereby increasing the engagement force between the revolving cover 10 and the cam drive unit 20.
    [0074] [074] Therefore, the cam drive unit 20 is attached to the swivel cover 10 by means of the restriction protrusion 21, and the engagement force between the cam drive unit 20 and the swivel cover 10 can increase thanks to the flange of support protrusion fitting 23. Therefore, the application of torque through the revolving cover 10 can be effectively transferred to the cam drive unit 20, thus improving the efficiency of the structure of the cord clamping device 100.
    [0075] [075] In addition, a support member 24 is formed on a underside of the rim of the cam drive unit 20. Here, the support member 24 supports, while allowing the cam base part 50 and the drive unit the cam drive 20 are spaced apart, thus forming a space in which the lift cam part 30 ascends or descends up and down along the cam protrusion part 22a.
    [0076] [076] In addition, the support member 24 rotates, contacting the upper surface of the cam base part 50, as the cam drive unit 20 rotates. At a predetermined angle, it contacts a support member engagement flange 54 formed on the cam base part 50, thus transferring the torque.
    [0077] [077] Here, the predetermined angle above means a rotation angle that defines a state of an escape from the spool part 40 as the lift cam part 30 rises through the rotations of the cam drive unit 20, in a state in the which the lifting cam part 30 and the spool part 40 are engaged.
    [0078] [078] Namely, the cam drive unit 20 rotates independently of the cam base part 50 within the scope of a predetermined rotation angle, thus allowing the lift cam part 30 to ascend or descend, and at least predetermined rotation angle above, rotate integrally with the cam base part 50.
    [0079] [079] Therefore, the support member 24 and the support member engagement flange 54 allow to effectively transfer the torque to the cam base part 50, in the case where the swivel cover 10 rotates by a predetermined angle, thus improving , convenience, when in use, and to distribute, so that the transferred force does not concentrate on a predetermined part, thereby improving reliability by enhancing product durability.
    [0080] [080] In addition, the pressing protrusion 25 protrudes from a lower side of the rim of the cam drive unit 20 and is inserted into the sliding groove part 55 disposed between the inner circumference of the cam base part 50 and the unit winding 52a of the ratchet coupling part and rotates, thus allowing the winding unit 52a to slide. Once it contacts by sliding and pressing, the winding unit 52a of the ratchet coupling part 52 can be deformed selectively and elasticly.
    [0081] [081] Namely, since the pressing protrusion 25 is inserted into the slide groove part 55 of the cam base part 50 and slides based on the rotation of the cam drive unit 20, the winding unit 52a can be selectively pressed and elastically deformed based on the position in which the pressing protrusion 25 slid. Therefore, the ratchet coupling part 52 can be supported elasticly by the ratchet type gear 62 thanks to the elastic deformation of the winding unit 52a.
    [0082] [082] In addition, the rotating shaft connection unit 22 is formed on the inside of the cam drive unit 20 and is formed in a cylindrical shape that protrudes downwards. Here, the rotary axis 70 supported by the rotary cover unit 10 passes through the inner circumference of the rotary axis connection unit 22.
    [0083] [083] At this time, it is preferred that the cam protrusion part 22a formed in the inclined type is formed on the outer circumference of the rotating shaft connection unit 22, so that it can ascend circumferentially in a clockwise direction along a external circumferential surface. In addition, the cam protrusion part 22a includes a lift cam part 30 which can ascend and descend by sliding along the inclined surface of the cam protrusion part 22a when the cam drive unit 20 rotates.
    [0084] [084] In fact, the inner circumferential cam groove part 32 and the cam protrusion part 22a are formed obliquely to ascend when rotated clockwise, and the sloped surface formed can be formed into a screw shape spiral at a predetermined slope.
    [0085] [085] Thus, the cam protrusion part 22a and the inner circumferential cam groove part 32 are engaged in a sliding contact way, thus the force can be transferred efficiently when the cam protrusion part 22a slides in the inner circumferential cam groove part 32 and slide out, thereby preventing any abrasion due to friction, thus it is possible to improve the convenience when in use and durability of products.
    [0086] [086] Meanwhile, the cam base part 50 includes an orientation cam part 51, a support member snapping rim 54, a sliding groove part 55, an inner circumferential unit 58 in which the coupling part of ratchet 52 is formed, and an outer circumferential unit 59 in which the lock groove part 56 is formed.
    [0087] [087] Here, the outer circumferential unit 59 is swiveled to cover the top rim of the housing part 60, and the inner circumferential unit 58 is arranged to cover the lift cam part 30. At that point, the outer circumferential unit 59 and inner circumferential unit 58 can be injection molded, and it is preferred that they are integrally connected during injection molding.
    [0088] [088] Furthermore, it is preferred that, on the cam base part 50, the ratchet coupling part 52 is formed in the winding unit 52a that extends along a circumference in the inner circumferential unit 58. Here, the part coupling ratchet 52 is interlocked, so that counterclockwise rotation can be restricted by the ratchet type 62 gear. In addition, the ratchet coupling part 52 is connected to the winding unit 52a, made of elastic material, which extends over a predetermined length of the internal circumferential unit 58.
    [0089] [089] Therefore, the winding unit 52a elastically supports the ratchet coupling part 52 which is fitted to the ratchet type gear 62, and the counterclockwise rotations of the cam base part 50 can be safely restricted, and in the case of clockwise rotations, the ratchet coupling part 52 can move smoothly along the inclined surface of the ratchet type gear 62, since the winding unit 52a is elastically deformed.
    [0090] [090] In addition, the elastic deformation of the winding unit 52a can be selectively controlled by the pressing protrusion 25 inserted in the slide groove part 55, it is possible to safely restrict the rotations in the counterclockwise direction of the cam base part 50 , and clockwise rotations can move more smoothly. Thus, the actuation to tighten the cord by rotating the rotating cover in a clockwise direction can be performed in a more convenient way, which makes it possible to improve convenience when in use.
    [0091] [091] In addition, the guide cam part 51 is inserted into the outer circumferential cam groove part 31 of the lift cam part 30, thereby directing the rise and lowering of the lift cam part 30 based on the direction of rotation of the cam drive unit 20.
    [0092] [092] In addition, the lock groove part 56 opens at an established rotation angle, and the lock protrusion 16 inserts and swivels at a predetermined angle.
    [0093] [093] At that time, the lock groove part 56 is formed, so that the lock protrusion 16 can move in the lock groove part 56 within a predetermined rotation angle, and by the predetermined rotation angle, contact the ends of the lock groove part 56 are clamped so that the lock protrusion 16 can receive torque.
    [0094] [094] It is preferred that the support member engaging edge 54 is formed on the upper surface of the cam base part 50. Here, the support member engaging edge 54 allows the cam base part 50 to be fully rotated and the cam drive unit 20 upon receiving the torque at a predetermined angle, while the cam drive unit 20 rotates, contacting the upper surface of the cam base part 50.
    [0095] [095] Therefore, the mounting flange of the support member 54 and the support member 24 make it possible to distribute and transfer the torque if the swivel cover 10 rotates by a predetermined rotation angle, next to the lock protrusion 16 of the swivel cover 10 and the lock groove part 56 of the cam base part 50.
    [0096] [096] Therefore, it is possible to prevent the lifting cam part 30, the cam drive unit 20 and the cam base part 50 from wearing or breaking while the cam drive unit 20 and the cam base part cam 50 are transferring torque, thereby improving product durability, and product reliability can be improved by reducing error operations.
    [0097] [097] In addition, the guiding cam part 51 is formed in the inner circumferential unit 58 of the cam base part 50, but is fitted to the outer circumferential groove 31 of the lifting cam part 30, thereby guiding the rise and lowering the lifting cam part 30.
    [0098] [098] Here, it is preferred that the outer circumferential cam groove part 31 and the guiding cam part 51 have the inclined types that are opposed to the inner circumferential cam groove part 32 and the cam protrusion part 22a. At that time, the cam base part 50 is fixed and, since the guiding cam part 51 is formed in the inclined type, which is opposite the cam protruding part 22a, the lifting cam part 30 can ascend and descending by sliding up and down along the cam portion 51 based on the direction of rotation of the cam drive unit 20.
    [0099] [099] In this way, the cord clamping device 100 can tighten or release the cord simply by rotating the swivel cover 10 clockwise or counterclockwise, thus the operation is easy, thus, improving convenience when in use.
    [0100] [0100] Meanwhile, the swivel cover 10 includes a restraining groove part 11, a lock protrusion 16, a support protrusion 13, a friction protrusion 15, a magnetic coupling unit 12 and a rotary shaft support unit 14. Here, the restriction groove part 11 is formed on a lower surface of the swivel cover 10, and in the restriction groove part 11, a restriction protrusion 21 protruding from the upper side of the cam drive unit 20 is fixedly inserted.
    [0101] [0101] In addition, it is preferred that the support protrusion 13 is formed on a lower surface of the rotating cover 10. At that time, the support protrusion 13 supports the support protrusion fitting rim 23 formed in the cam drive unit. 20. Therefore, with the support protrusion 13, the revolving cover 10 can reattach the cam drive unit 20 engaged by the restriction groove part 11.
    [0102] [0102] Therefore, the swivel cover 10 supports a side surface of the cam drive unit 20 when rotating integrally, fitted to the cam drive unit 20, thus restricting the top, which allows to improve the integrity. Since the torque can be transferred efficiently with the improved integrity, the structural efficiency of the cord clamping device 100 can be improved.
    [0103] [0103] In addition, the friction protrusion 15 is made in a structure in which a protrusion and a concave groove are alternately formed in the circumferential direction on the outer circumferential surface of the revolving cover 10, and is preferably made of an elastic material, extensible, for example, synthetic rubber etc. Therefore, it is possible to improve the frictional force and grip feeling by pressing and rotating the swivel cover 10 with a user's finger.
    [0104] [0104] In addition, the lock protrusion 16 is formed in the form of an inclined protrusion on the underside of the inner circumferential surface of the revolving cover, where the protrusion becomes bulky towards the top of the revolving cover 10. Here, the lock protrusion 16 is inserted into the lock groove part 56 formed on a underside of the cam base part 50, thus engaging the swivel cover 10 with the cam base part 50.
    [0105] [0105] At this point, the sloping surface of the protrusion meets the outer circumferential surface of the cam base part 50 and slides, and the vertical angle surface becomes trapped in the lock groove part 56, thus obtaining the most easy and improving the coupling force.
    [0106] [0106] In addition, as pictured in FIGURE 3, the lock protrusion 16 is inserted into the lock groove part 56. Once the lock groove part 56 is opened at an established rotation angle, the rotating cover 10 it is engaged, covering the outer circumference of the cam base part 50, and is rotatable at a predetermined angle.
    [0107] [0107] In other words, if the torque is applied to the rotating cover 10, the lock protrusion 16 can move within the lock slot part 56 and within an established rotation angle. In addition, excessively at the established angle of rotation, the lock protrusion 16 becomes attached at both ends of the lock groove part 56, thereby transferring torque to the cam base part 50.
    [0108] [0108] Therefore, the torque that applies to the swivel cover 10 and within the rotation angle does not apply to the cam base part 50, the swivel cover 10 and the cam drive unit 20 can rotate independently of the base part of cam 50. At that moment, the application speeds are transferred to the cam drive unit 20, thus raising and lowering the lifting cam part 30.
    [0109] [0109] In addition, in excess of the rotation angle, the torque, which was applied to the swivel cover 10, is transferred to the cam drive unit 20 and the cam base part 50, so that the swivel cover 10 , the cam drive unit 20 and the cam base part 50 can rotate integrally.
    [0110] [0110] Thus, counterclockwise rotation applies to the swivel cover 10 to cause the spool part 40 to separate from the lift cam part 30, and when the spool part 40 to separate and become independently rotating, rising and lowering can be restricted to stop. Therefore, the cord clamping device 100 can prevent error operation by precisely adjusting the tightening state and the release state, thereby improving convenience when in use, and can prevent any damage to the products by preventing excessive force from application to internal components, thus product reliability can be improved.
    [0111] [0111] In addition, the top of the pivot shaft 70 is inserted and fitted to the pivot shaft support unit 14 formed on the bottom surface of the pivot cover 10. Here, the pivot shaft 70 passes through the spool part 40, the part of the cam base, the lifting cam part 30 and the cam drive unit 20 and supports them in a rotating manner. The pivot shaft 20 covers the set screw 80 which passes through the pivot cover 10 and is fitted to the housing part 60 ...
    [0112] [0112] Therefore, since the rotary axis 70 is fixed to precisely support the rotation movements by which the cord clamping device 100 is activated, the raising and lowering of the lifting cam part carried out by the rotations and the selective fitting the spool part 40 and the lifting cam part 30 can be driven efficiently, thereby improving convenience when in use and structural efficiency.
    [0113] [0113] Hereinafter, the raising and lowering operations of the lifting cam part 30, which allow the separation and fitting of the ratchet-type protrusion 43 of the spool part 40 and the slide protrusion 33 of the lifting cam part 30 will be described in more detail.
    [0114] [0114] FIGURES 4A and 4B are seen in partial projection cross section after the inner circumferential cam groove part and the cam protrusion part on the rear side are projected in the cross section obtained along line AA 'in FIGURE 3 Namely, the partial cross-sectional view is indicated with a dotted line after the projection of the inner circumferential cam groove part 32 on the inner side of the lift cam part 30 and the cam protrusion part 22a, which are not depicted in the cross section cut along line AA 'in FIGURE 3.
    [0115] [0115] As pictured in FIGURES 4A and 4B, on the cord clamping device 100, the lifting cam part 30 can ascend or descend with the cam drive unit 20 rotations that occur as the user rotates the rotating cover 10 in one direction or in the other direction, thus, it can be selectively fitted with the spool part 40 in the structure above.
    [0116] [0116] At that moment, in the event that the lift cam part 30 descends, the lift cam part 30 is fitted to the spool part 40 and is driven to turn integrally, thus winding the cord "w" and, in the case in which the lift cam part 30 rises, the spool part 40 separates from the lift cam part 30 and rotates independently, thereby extracting and releasing the cord. Furthermore, in the event that the external force of the user is interrupted, the spool part 40 can maintain a tight state with the help of the cooperation of the lifting cam part 30 and the cam base part 50.
    [0117] [0117] In detail, if the user rotates the rotating cover 10 clockwise, the torque in the clockwise direction is applied to the cam drive unit 20 via the restraining groove part 11 formed on the bottom surface of the rotating cover 10.
    [0118] [0118] Here, in the case in which the swivel cover 10 rotates within the established rotation angle, the lock protrusion 16 of the swivel cover 10 and the support member 24 of the cam drive unit 20 do not transfer torque to the base part of cam 50.
    [0119] [0119] Therefore, when the cam drive unit 20 rotates clockwise and within the angle of rotation, the cam protrusion part 22a slides and escapes, while pushing the slanted surface upward in the clockwise direction of the part of inner circumferential cam groove 32 and rotates at reduced angle of rotation, while moving the up and down ac unit [SIC] downwards 30. At that moment, the outer circumferential groove 31 slides along the sloping surface downward in the direction time of the guide cam part 51, and the lift cam part 30 can descend.
    [0120] [0120] At this moment, the application of torque in the clockwise direction can be applied through the transfer path, in sequence, the rotating cover 10, the restriction groove part 11, the restriction protrusion 21, the drive unit of cam 20, the cam protrusion part 22a, the inner circumferential cam groove part 32, the lift cam part 30, and the outer circumferential cam groove part 31.
    [0121] [0121] In addition, the slide protrusion 33 formed on the lower surface of the lifting cam part 30 is fitted to the ratchet-type protrusion 43 formed on the upper surface of the spool part 40.
    [0122] [0122] Here, if the torque is applied continuously in a clockwise direction, the torque that has been transferred to the rotating cover 10 applies from the lock protrusion 16 to the lock slot part 56 and, at the same time, the torque that has been transferred from the swiveling cover 10 to the cam drive unit 20 is transferred by means of the support member 24 to the support member engaging edge 54 of the cam base part 50.
    [0123] [0123] Therefore, the swiveling cover 10, the cam drive unit 20 and the cam base part 50 rotate integrally, and the lift cam part 30 can remain attached to the spool part 40. At that time, the slide protrusion 33 formed on the lower surface of the lifting cam part 30 is engaged, while corresponding in shape with the ratchet type protrusion 43 formed on the upper surface of the spool part 40.
    [0124] [0124] Namely, the ratchet-type protrusion 43 has an inclined surface that protrudes upwards in a counterclockwise direction along the circumference of the spool part 40, and the slide protrusion 33 has an inclined surface that protrudes to down in the clockwise direction along the circumferential direction of the bottom surface of the lifting cam part 30. Therefore, the vertical surface of the slide protrusion 33 meets the vertical surface of the ratchet-type protrusion 43, thereby efficiently transferring torque.
    [0125] [0125] At that moment, the torque that was applied to the rotating cover 10 applies to the spool part 40, and the spool part 40 rotates clockwise, thus winding the "w" cord. In more detail, the torque transfer path that has been applied to the swivel cover 10 is formed following the swivel cover 10, the restriction groove part 11, the restriction protrusion 21, and the cam drive unit 20.
    [0126] [0126] At the same time, the torque is transferred in sequence from the rotating cover 10, the lock protrusion 16, the lock groove part 56, the cam base part 50, and the ratchet coupling part 52. In addition In addition, the torque that has been applied to the cam drive unit 20 can be divided into the torque that is transferred in the sequence of the support member 24, the support member engagement rim 54, the cam base part 50 and the ratchet coupling part 52, and the torque that is transferred following the cam protrusion part 22a, the inner circumferential cam groove part 32, the lift cam part 30, the slide protrusion 33, the protrusion of the type ratchet 43, and the spool part 40.
    [0127] [0127] In addition, external force is applied to the "w" cord, for example, in the case in which the user who carries an item moves or the "w" cord is forcibly pulled, in a state in which the supply of the user's external force stopped after the cord "w" was wound as it is properly tightened and then the force applied in the release direction, the torque can be applied from the cord "w" to the spool part 40 in the direction anticlockwise.
    [0128] [0128] Here, since the spool part 40 remains attached to the lifting cam part 30, torque of the spool part 40 is applied via the vertical surface of the ratchet-type protrusion 43 and the vertical surface of the slide protrusion 33 , so that the torque in the counterclockwise direction applies to the lifting cam part 30.
    [0129] [0129] At this point, the torque in the counterclockwise direction allows the inner circumferential cam groove part 32 to slide downwards from the sloping surface in the clockwise direction of the cam protrusion part 22a, however, since already contact the spool part 40, it cannot descend. Therefore, the counterclockwise torque that has been applied to the lifting cam part 30 is transferred to the guiding cam unit 51 via the outer circumferential cam groove part 31.
    [0130] [0130] Here, part of the torque compensations when the force on the outer circumferential cam groove part 31 is intended to ascend relative to the downwardly sloping surface of the guiding cam part 51 meets the force on the internal circumferential cam groove 32 which is designed to slide downwards along the upwardly sloping surface in the clockwise direction of the cam protrusion part 22a, and part of the torque is transferred to the cam base part 50.
    [0131] [0131] At this time, the counterclockwise rotation of the cam base part 50 is restricted by the housing part 60, the tight state of the "w" cord can be maintained.
    [0132] [0132] Meanwhile, if the user rotates the rotating cover 10 in a counterclockwise direction, the torque in a counterclockwise direction is transferred to the cam drive unit 20 via the restriction groove part 11 formed on the bottom surface swivel cover 10.
    [0133] [0133] In the case where counterclockwise torque is generated within a predetermined rotation angle, the lock protrusion 16 of the swivel cover 10 and the support member 24 of the cam drive unit 20 do not transfer torque to the cam base part 50. In addition, the cam base part 50 is fixed in a state in which the counterclockwise rotation is restricted by the housing part 60.
    [0134] [0134] Therefore, the cam protrusion part 22a slides down along the upwardly sloping surface in the clockwise direction of the inner circumferential cam groove part 32, meanwhile the lift cam part 30 rotates at the reduced angle of rotation counterclockwise while moving upward. At that time, the outer circumferential cam groove part 31 slides on the sloping surface upward in the counterclockwise direction of the guide cam part 51, and the lift cam part 30 can ascend.
    [0135] [0135] Therefore, the slide protrusion 33 formed on the lower surface of the lifting cam part 30 separates from the ratchet type protrusion 43 formed on the upper surface of the spool part 40. Here, since the sloping surface of the slide protrusion 33 meets the inclined surface of the ratchet-type protrusion 43 and slides, if the lifting cam part 30 rises along the counterclockwise direction of the cam drive unit 20, it can smoothly detach from the spool part 40 .
    [0136] [0136] Since the spool part 40 is rotatable independently, without being restricted by the lifting cam part 30, if the user grips both ends of the "w" cord and extract the "w" cord, the part reel 40 spins freely and independently, thus easily releasing the "w" cord.
    [0137] [0137] At this point, the transfer path of the transferred torque is in sequence of the rotating cover 10, the restriction groove part 11, the restriction protrusion 21, the cam drive unit 20, the cam protrusion part 22a , the inner circumferential cam groove part 32, the lift cam part 30 and the outer circumferential cam groove part 31.
    [0138] [0138] FIGURE 5 is a perspective view depicting a state in which the logo mark is affixed to the magnetic coupling unit of the cord clamping device, in accordance with an embodiment of the present invention.
    [0139] [0139] As pictured in FIGURE 5, the magnetic hitch unit 12 can be provided on the swiveling cover 10. Here, to the magnetic hitch unit 12, the logo mark 17 made of a ferromagnetic metal can be selectively attached. At that time, an image or character corresponding to the user's personality and preference can be formed in the logo mark 17. It is possible to form a graphic representation of the brand or a name corresponding to the manufacturer of the item to which the lanyard fixing device 100 is attached. applies.
    [0140] [0140] Therefore, the cord clamping device 100 allows you to change the logo mark 17 freely and easily, based on the personality and preference of the user. In addition, the logo mark including the graphic representation of the brand or the name can be affixed to the magnetic hitch unit 12 based on the demand of the manufacturer of the item to which the lanyard fixing device 100 applies. Therefore, the cord clamping device 100 can improve efficiency based on product design and product advertising effects.
    [0141] [0141] In fact, the logo mark 17 can be formed by covering the front side of the revolving cover. Here, the logo mark 17 can be affixed and detached freely, since it is affixed using magnetic force, even when the logo mark 17 has a predetermined size or shape that can interfere with the operation of the revolving cover, for which the convenience when in use can be maintained, while improving efficiency based on design.
    [0142] [0142] As described above, it is noted that the present invention is not limited to the disclosed embodiments. Any modifications are available to those skilled in the art to which the present invention belongs without departing from the scope of the claims of the present invention, and it is obvious that these modifications belong to the scope of the present invention. INDUSTRIAL APPLICABILITY
