    The invention relates to a door hinge device comprising a height adjustment device that allows to correct vertical displacement on a hinge which can be generated by various factors, such as a design error generated when the door is designed, or downward displacement of a second bracket due to a weight of the door. The invention is thus able to ensure and maintain an accurate opening and closing function of a door, and also to minimize the generation of frictional noise or damage to a component due to friction on a door hinge device in which a door hinge between a first retaining bracket and a second bracket is provided, is generated due to friction.
    In general, a revolving door has a structure in which a side surface of the door is fixedly installed within a support frame of a door frame on which the door is installed, and a door hinge with a rotation axis installed in such a fixing installation surface, to allow the door to rotate horizontally, which allows the door to be opened and closed.
    Many products of various shapes and structures have been developed and used as such a door hinge. When a general door hinge using the most widely used pin hinge rod is used, vertical displacement due to a vertical load of a door does not generally occur unless a hinge frame for supporting the hinge rod and a fastener for attaching the hinge frame to the door are deformed Door or the support frame of the door frame has sufficient strength. However, since strength against a torque applied to a vertical surface between an upper end and a lower end of the door is weak, the size and strength of a hinge joint part and a size and strength of a fastener (anchor) thereof should also be increased, as the door gets bigger, and with that it becomes difficult for the door to get bigger. Further, since response to customer demand for minimizing and decreasing a cross-sectional dimension of the door (or a cross-sectional dimension of the door frame for supporting a glass constituting the door) while increasing a size of the door and increasing the size of the fastener (anchor) conflict with each other , there is a limit to solving the problem.
    A gear hinge (a gear hinge or a toothed hinge) shown in Figures 1 to 12 and having a structure different from that of the general hinge part with the pin hinge rod has been developed and used as a structure that can minimize the torque on the vertical surface of the door between the top and bottom of the door corresponding to an over-sized door inclination.
    In order to better understand the present invention, a detailed configuration of the interlocking hinge and application examples of a rotating door using this interlocking hinge will be described below.
    In a rotating door 100U shown in Fig. 1 to 3, a first bracket 31, which forms a toothed hinge 30 which is fixedly connected to a vertical frame of a support frame 10 of a door frame by a screw 30a, and a second retaining bracket 32, which forms the toothed hinge 30, firmly connected to a side surface of a door 20 by the screw 30a and teeth 31a and 32a, which are formed in the longitudinal direction on surfaces of the first retaining bracket 31 and the second retaining bracket 32 facing each other are engaged with each other, and a rotation support frame 33 (refer to FIG. 3) that supports the gear parts 31a and 32a on a rear side thereof between the first bracket 31 and the second bracket 32 is provided so that the first bracket 31 and the second retaining bracket 32 can be rotated while hanging, while the toothings 31a and 32a of the first retaining bracket 31 and of the second retaining bracket 32 Are held in an engaged state with each other, and tooth portions thereof which are engaged with each other are moved.
    Here, the toothed hinge 30 has a planar rotational structure that offers a high resistance force against the torque and a smooth rotational action, as shown in FIGS. 4 and 7. As shown in Figure 4, protruding articulated shaft sections 33a, which are angled at both ends of the rotary support frame 33, are rotatably inserted into rotary shaft pockets that are formed on one side that the toothings 31a and 32a, each at one end of the first bracket 31 and the second bracket 32 are provided opposite to be engaged with each other. And, as shown in Figs. 5 and 6, the first bracket 31 and the second bracket 32 are interlocked with each other to rotate the pivot shaft portions 33a protruding from the axis, which are formed at both ends of the rotating support frame 33, about the axis. For example, when the first retaining bracket 31 is attached to one side of the support frame 10 of the door frame and the second retaining bracket 32 is attached to one side of the door 20, the second retaining bracket 32 is rotated relative to the stationary retaining bracket 31, as shown in FIGS. 5 to 7.
    Furthermore, when axial rotation of the second bracket 32 is restricted, as shown in FIG. 7, excessive rotation is prevented. This is realized when outer shoulders of the angled portions formed at both ends of the rotary support frame 33 are received in the shoulder bags 31b and 32b. The shoulder bags 31b and 32b are formed on outer side surfaces of the first bracket 31 and the second bracket 32, which rotate outward.
    The structure in FIGS. 4 to 7 is an example in which the second retaining bracket 32 can be rotated by approximately 180 ° with respect to the first retaining bracket 31.
    As shown in Fig. 8, allow the serrations 31a and 32a, which are formed in the longitudinal direction on both sides of the first bracket 31 and the second bracket 32 to be rotated and folded, and the rotating support frame 33, the rotation of the toothings 31a and 32a supports, while the toothings 31a and 32a are in engagement with one another, smooth rotation between the first retaining bracket 31 and the second retaining bracket 32 in a horizontal plane. Further, the serrations 31a, 32a and the rotating support frame 33 also offer a structure in which serration teeth, which are formed long in the longitudinal direction, are engaged with each other. Accordingly, even if the torque on the vertical surface of the door between the upper end and the lower end of the door is increased due to a large size of the door 20, it is possible to sufficiently respond to the increased torque, thereby providing structural stability. which can minimize the possibility of a distortion phenomenon in an installation direction or position of the door.
    As shown in Fig. 9, the first bracket 31 and the second bracket 32 which are rotated while being connected to each other by the serrations 31a and 32a formed in the longitudinal direction on both sides thereof. The first retaining bracket 31 and the second retaining bracket 32 can have a cross-sectional structure in which the second retaining bracket 32, which is firmly connected to the side of the door 20, can be longitudinally displaceable with respect to the first retaining bracket 31, which is fixed to the side of the support frame 10 of the door frame is connected. Therefore, in order to prevent this, openings 31c and 32c are respectively formed on the first bracket 31 and the second bracket 32 to face each other as shown in FIGS. 10 and 11. Further, a vertical hooking tool 34 is jointly inserted into the openings 31c, 32c facing each other, and then fixed to an inner surface of the rotary support frame 33 through a fixing hole 35, as shown in FIGS. 10 and 11. Furthermore, one end of the hooking tool 34 is geometrically adapted and accommodated in an interior space of the rotary support frame 33 and thus forms the gear hinge 30.
    An upper surface and a lower surface of the vertical hooking tool 34, which is provided to limit the longitudinal displacement generated between the first bracket 31 and the second bracket 32, and also to support a vertical load, carries cross sections of Portions of the serrations 31a and 32a of the first bracket 31 and the second bracket 32 where the openings 31c and 32c are formed while being rubbed thereby when the door is rotated to open and close. The upper surface and the lower surface of the vertical hooking tool 34 are therefore formed from a synthetic resin material which has a low coefficient of friction and prevents friction noise, unlike the first bracket 31 and the second bracket 32 which are generally made of a metallic material such as for example an aluminum alloy are formed.
    However, in an actual situation where the large door 20 is installed on the support frame 10 of the door frame through the aforementioned toothed hinge 30 as shown in Fig. 12, a downward displacement exerted on the second bracket 32 by a weight W of the door 20 fixed to the side of the door 20 acts a frictional force on a cross section contacting the vertical hooking tool 34, and thus excessive friction noise is generated when the door is rotated to be opened and closed. There is a problem that it is difficult to avoid rubbing noise generated by the large door with only the above material solution.
    Of course, the frictional force on the cross section that brings the vertical hooking tool 34 into contact can be reduced by lifting the door 20 attached to the second support bracket 32 with various types of known lifting devices using hydraulic means or the like and thereby applying an upward displacement to the second retaining bracket. However, it is almost impossible to accurately adjust a height in a range of 0.1 mm to 0.5 mm using such lifting devices, and an excessive cost is incurred in enabling the same.
    So far, the problems in the prior art relating to a door hinge device of a rotating door have been described focusing on the example in which the toothed hinge is used. As long as a structure is provided in which vertical displacement or spacing can occur between components constituting a door hinge of a rotating door, substantially the same technical problems as those in the interlocking hinge are created even if a detailed configuration of the hinge part changes becomes.
    The present invention is directed to providing a simple device which can regulate a vertical displacement or a distance between components forming a door hinge accordingly, even when the vertical displacement or the distance by weight of a door forming a rotating door , is produced.
    In particular, the present invention is directed to providing a device capable of accurately introducing a vertical upward displacement to a second retaining bracket in steps to reduce friction when a downward displacement is generated on one side of the second retaining bracket, the is fixedly connected to one side of a door to form a toothed hinge of a rotating door, and a rubbing noise at a cross section that contacts a vertical hooking tool is increased.
    [0018] This object is achieved by the features of claim 1. Advantageous embodiments and developments of the invention are described in the dependent claims.
    The present invention according to claim 1, comprises a height adjustment device.
    Here, each of the thin height adjusting plates can advantageously be formed by machining a thin metal plate material including a stainless steel plate into a thin plate having a thickness of 0.1 mm to 0.2 mm. As a result, an entire height range from about 0.1 mm to 1 mm can be finely divided and set in small height adjustment steps from 0.1 mm to 0.2 mm.
    Furthermore, a rounded portion is advantageously provided on upper edges of an adjacent portion between the first support plate and the second support plate or on an edge of a lower surface of the sliding block to enable smooth sliding movement of the sliding block passing through an adjacent portion, which has a height difference between the first support plate and the second support plate.
    A door hinge with height adjusting device for rotating a door according to the present invention can have the following effects.
    According to a basic configuration of the present invention, it is possible, even if a vertical displacement or a distance between a first bracket and a second bracket of components of a door hinge part is generated by a weight of a door that forms a rotating door, appropriately and precisely to regulate the vertical displacement or the distance by a simple device, and it is thus possible to minimize the friction, wherein the second bracket is rotated relative to the first bracket and other components.
    In particular, in one case, a rubbing noise of a vertical hooking tool in a toothed hinge can be minimized by precisely controlling a relative height between the door and the second bracket, thereby alleviating a noise generation problem due to the enlargement of a door size.<tb> Fig. 1 <SEP> is a perspective view showing an installation state of a revolving door with an upper end portion enlarged.<tb> Fig. 2 <SEP> is a perspective view showing the installation state of the rotating door, with a lower end portion enlarged.<tb> Fig. 3 <SEP> is a perspective view showing a toothed hinge constituting a door hinge of the rotating door of FIGS. 1 and 2.

    A configuration of a rotating door which uses the door hinge with height adjustment device 300 described with reference to FIGS. 13 to 16 is described below with reference to FIGS. 17 and 18.
    Fig. 17 shows an example of a rotating door. The rotating door is provided with the door 20 having a door handle 20h which forms the rotating door and a door hinge 30, one side surface of which is rotatable with the support frame 10 a door frame is connected. The door hinge 30 comprises the first retaining bracket 31 which is fixedly connected to the side of the support frame 10 of the door frame; a second bracket 32 fixedly connected to the side of the door 20; and a hinge part that is provided to be relatively rotated between the first bracket 31 and the second bracket 32. Here, a portion of Fig. 17 indicated by the reference numeral 33 is the hinge part which is provided to be relatively rotated between the first bracket 31 and the second bracket 32, and when the rotating door on which the The present invention relates to the toothed hinge shown in Figures 1 through 12 as door hinge 30, reference numeral 33 may include the pivot support frame, configuration of the serrations supported on the pivot support frame, and the like.
    In particular, when the hinge part is provided as the toothed hinge, surfaces of the first bracket 31 and the second bracket 32 that face each other include serrations 31a and 32a formed in the longitudinal direction to be engaged with each other. The rotating support frame 33 supports the teeth 31a and 32a on a rear side between the first retaining bracket 31 and the second retaining bracket 32, so that the first retaining bracket 31 and the second retaining bracket 32 are rotated about the hinge, while the teeth 31a and 32a of the first retaining bracket 31 and the second retaining bracket 32 are held in an engaged state with each other. In the pivot shaft pockets formed on one side of the first retaining bracket 31 and the second retaining bracket 32, which are opposite to the teeth 31a and 32a, are the protruding articulated shaft sections 33a, which are formed so that they are angled from both ends of the pivot support frame 33 , inserted rotatable.

    18 shows an operating state in which the door 20 is opened and closed by a rotating action of the second retaining bracket 32 with respect to the first retaining bracket 31. In a state B in which the door 20 is partially open - in contrast to a state A in which the door 20 is closed - the lower end frame 10d of the support frame 10 of the door frame is also shown.
    When the door hinge device comprising a height adjuster 300 according to the preferred embodiment of the present invention is installed on the rotating door having the configuration described above, the slide block 380 fixed and attached to a lower surface of the door 20 slides at the lower end of the Door 20, which is rotated together with the second retaining bracket 32, which is rotated relative to the first retaining bracket 31, forming the door hinge 30 with support between the first support plate 321 and the second support plate 322, divided on a plane along the rotational path of the door 20 as shown in Figs.
    Fig. 20 shows a position of the slide block 380 indicated by a broken line, a state (the state A of Fig. 18) in which the door 20 is closed, a position of the slide block 380 indicated by a alternately long and short dashed lines shows a state (the state B of Fig. 18) in which the door 20 is opened by about 90 ° and shows a position of the slide block 380 indicated by a solid line a state in which the door 20 is fully opened by about 180 °. It should be understood that the slide block 380 is set on an upper surface of the second support plate 322 when the door 20 is fully opened by about 180 degrees, and the slide block 380 is set on an upper surface of the first support plate 321 when the door 20 is opened is closed, and the slide block 380 is disposed at an adjacent portion between the first support plate 321 and the second support plate 322 while the door 20 is opened by about 90 °.
    In this situation, if a difference in the number of the thin height adjusting plates 330 are stacked and arranged between each of the first support plate 321 and the second support plate 322 and the door support block 310 for supporting both the first support plate 321 and the second support plate 322, a height of the first support plate 321 and the second support plate 322 disposed thereon is changed, and thus a height of a surface that supports the slide block 380 that slides along the upper surface is also changed by a thickness of the thin height adjustment plate 330, and the door 20 can create a vertical displacement distance between the components that make up the door hinge by performing a rotary action about the door hinge 30, and fine play adjustment can be allowed therethrough.
    19 and 20 are plan views, and since it is difficult to show a detailed height-adjusting operation by the drawings, cross-sectional views are taken along line A-A of Fig. 20 showing the operation shown in Figs. 21-28.
    FIG. 21 shows a closed state of the door 20, indicated by the dashed line in FIG. 20, and FIG. 22 is an enlarged view of a section B1 of FIG. 21.
    According to FIGS. 21 and 22, the thin height adjustment plates 330 have two thin height adjustment plates under the first support plate 321, which are identified by the reference numerals 330-1 and 330-2 in FIG. 22, and the second thin height adjustment plates 330 below the second support plate 322 have three thin height adjustment plates, which are denoted by the reference numerals 330-1, 330-2 and 330-3 in FIG. Therefore, a height of the second support plate 322 is higher than that of the first support plate 321 denoted by reference numeral 330-3 by a thickness of the thin height adjusting plate, and a position of the slide block 380 is placed on the first support plate 321 in this state. This state can be achieved by loosening and separating the fastening screw 342 for fastening the second support plate 322 to the door support block 310 in the closed state of the door 20 and then increasing the number of second thin height adjusting plates 330 which are between the second support plate 322 and the door support block 310 be arranged to one (one is an example in the drawing, but the present invention is not limited thereto).
    In this situation, when the door 20 is rotated and opened by 180 ° by the rotating support frame 33, the state shown in Figs. 23 and 24 (partially enlarged view of a portion B2 of Fig. 23) is reached, and this state FIG. 13 is a position corresponding to that of the slide block 380 indicated by the solid line in FIG. 20.
    According to FIGS. 23 and 24, which partially correspond to the enlarged view of the section B2 of FIG. 23, the sliding block 380 is arranged on the second support plate 322 by the thickness of the thin height adjustment plate, denoted by reference numeral 330 -3, is higher than that of the first support plate 321 on which the sliding block 380 was previously arranged, and thus a vertical height of the door 20 and a relative vertical height of the second bracket 32, which forms the door hinge 30 with respect to the first bracket 31 , also increased by the thickness (eg 0.1 mm) of the thin height adjustment plate, which is denoted by reference number 330-3.
    In this state, the fixing screw 341 that fixes the first support plate 321 to the door bracket block 310 can be loosened, and then the number of the thin height adjustment plates 330 arranged between the first support plate 321 and the door bracket block 310 can be adjusted by one (one is an example in the drawing, but the present invention is not limited thereto) can be increased to have the same height as the second support plate 322, thereby restoring a normal door installation state as shown in FIGS. 25 and 26 which correspond to a partially enlarged view of a portion B3 of FIG. 25. In this state, when the door 20 is closed, the slide block 380 slides along a horizontal plane formed by the second support plate 322 and the first support plate 321, as shown in FIGS. 27 and 28, which are a partially enlarged view of a section B4 of FIG.
    Figs. 21 to 28 illustrate a one-step height adjustment, and a height can be finely adjusted by repeatedly executing the height adjustment process over several steps.
    At this time, the height of the first support plate 321 can be increased by two by increasing the number of the second thin height adjustment plates 330 to be higher than the second support plate 322, which are arranged between the first support plate 321 and the door support block 310, which is shown in FIG 25 and 26 are shown from the state shown in Figs. In this case, an upward movement effect of the slide block 380 is generated even when the door 20 is closed again.
    In the door hinge device for rotating a door comprising a height adjusting device 300 according to the present invention, the slide block 380, which is arranged at the rotating area divided on a plane along the rotating path of the door 20, can have a height that is different from the first support plate 321 and the second support plate 322, which are at different heights, is supported in stages by adjusting the number of first thin height adjusting plates 330 stacked and arranged between the first supporting plate 321 and the door support block 310 and the number of second thin height adjusting plates 330, stacked and disposed between the second support plate 322 and the door bracket block 310 by the above-described working methods, and thus a required relative vertical displacement can be caused between the components forming the door hinge.
    At this time, the slide block 380 attached and installed on a lower portion of the door 20 may be formed as a separate component as shown in the figure, attached and installed on the lower surface, or it may be integral be formed with the lower surface of the door 20. It should be understood by those skilled in the art that the present invention can also include such a structure.
