    The invention relates to a connecting member with a base body having an opening and a closure part which can be received in the opening, the closure part having a first end which is pivotably mounted on the base body and a second end which can be fixed on the base body by means of a locking device, wherein the locking device includes a pivot lever. Connecting links of this type can be used as a detachable, load-bearing element, for example to connect an external load to a helicopter, to connect a parachute, paraglider or hang-glider harness to the respective aircraft or to connect a tow line of a land or water vehicle to a towing vehicle -
    stuff.
    Carabiners with a snap lock are known from practice. Such a snap lock has play so that the snap lock can be easily opened and closed by spring force. Only when the base body is elongated below
    The snap lock enters the load positively and non-positively
    such a carabiner have high breaking loads.
    However, such a carabiner has the disadvantage that when the carabiner is subjected to vibrations, the snap lock of the carabiner is not loaded or is only loaded periodically. As a result, the side of the base body opposite the snap fastener experiences high, changing material stresses, so that the durability of the carabiner suffers. In addition, such a known karabiner has the disadvantage that it can no longer be opened under load as soon as it is under load
    the snap lock is in engagement with the base body.
    From DE 10 2004 039 166 A1 a connecting link is known which can be locked with a ball lock pin. Such a ball lock pin is held in a form-fitting manner on the base body even without an acting load, so that the stress on the material is reduced when exposed to vibrations. However, this known connecting link also has the disadvantage
    that opening under load is not possible.
    Proceeding from the prior art, the invention is therefore based on the object of specifying a connecting member which is operationally stable even when subjected to vibration and also under load
    can be opened easily.
    contains feather.
    According to the invention, a connecting member is proposed which has a base body having an opening. The base body can be made of a metal or an alloy or also of a fiber-reinforced plastic. In some embodiments of the invention, the base body can contain or consist of an aluminum alloy and be manufactured as a forged part, in particular by drop forging. The base body can have at least two straight, bent or curved legs and, for example
    have the basic shape of a C, D, U or V. The free ends
    Legs define the opening of the base body.
    Furthermore, the connecting member has a closure part that can be received in the opening of the base body. The closure part can also be straight or curved. Depending on the strength requirements, the closure part can also consist of a metal or an alloy or a fiber-reinforced plastic or contain these materials. In some embodiments of the invention, the closure part can contain an at least partially hollow element made of a light metal, in which a reinforcing element with greater strength is received, for example
    se made of a steel alloy.
    In some embodiments of the invention, the reinforcing element may contain or consist of a second dowel pin with a first end and an opposite second end, the first end of the second dowel pin being received in the closure part and the second end of the second dowel pin forming the second end of the closure part, which engages in the locking device on the base body. This can increase the strength and enable simple assembly, for example by gluing or
    Pressing in the second dowel pin. The dowel pin can be
    be.
    The closure part is pivotably mounted on one side on the main body, so that it can be moved from at least one first position into at least one second position, the opening being closed in the second position and at least partially released in the first position. In some embodiments of the invention, a closing spring can be arranged between the closure part and the base body, which spring acts on the closure part in such a way that it moves into its second
    Position is moved.
    Furthermore, the closure part has an opposite, second end, which can be fixed on the base body by means of a locking device. As a result, the closure element can be fixed in the second position and, when the locking device is triggered, pivot into the first position and release the opening. The locking device is designed such that, in at least one locked or closed position, it opposes a resistance to the pivoting movement of the closure part on the base body, which the closure part in the second position
    specifies.
    load that oscillates over time.
    In some embodiments of the invention, the pivot lever can be rotatable about an axis which coincides with the longitudinal extension of the closure part in the closed position. As a result, the pivot bearing of the pivot lever can be additionally stabilized and guided by the closure part or a part of the closure part, so that a smooth pivoting movement of the pivot lever and thus a simple release of the locking device is possible
    can be.
    th.
    In some embodiments of the invention, the pivot bearing can be provided with a cover. In some embodiments of the invention, such a cover can at least cover the spring chamber of the return spring to the outside. This prevents the ingress of moisture, dirt and snow, so that reliable operation even under rough conditions
    Environmental conditions is made possible.
    In some embodiments of the invention, the pivoting range of the pivoting lever can be limited by a guide slot into which a guide pin engages. The guide pin
    can be used in a hole in the base body.
    so undesirably detaches from the base body.
    In some embodiments of the invention, the guide pin can have an opening on the end face into which a second end of the return spring engages. This enables simple assembly of the locking device in that the restoring spring is inserted with a first end into an associated recess of the pivot lever and then tensioned with an assembly tool. When the guide pin is inserted into an associated opening on the base body of the connecting member, the guide pin is inserted into the guide slot on the one hand in order to prevent the pivot lever from falling out of the pivot bearing. At the same time, the second end of the return spring can be received in the front opening of the guide pin, so that relaxation of the return spring is avoided. In another embodiment of the assembly method, the return spring can be inserted in the relaxed state into the associated recess of the pivot lever, so that the second end of the return spring protrudes into the guide slot. Can do this
    the return spring is tilted or rotated to the end position
    End position to lie in the recess of the pivot lever.
    In some embodiments of the invention, the guide pin can be formed by a first dowel pin or a toggle pin or a dowel pin. Such a pen can go through
    Press-fit can be assembled in a simple manner.
    In some embodiments of the invention, the guide pin can be formed by a screw. This has the advantage that in the event that the assembly fails in the first attempt, the screw can be simply removed by unscrewing it. The individual components of the locking device can then be adjusted to one another again and the guide pin screwed in again. In some cases
    Guide forms of the invention, the guide pin by a
    manure reduced.
    In some embodiments of the invention, the guide pin can be glued into the base body. This prevents undesired loosening and increases operational reliability
    will.
    In some embodiments of the invention, the pivot bearing can contain at least one stop element which limits the movement of the locking device or of the pivot lever between the closed position and the open position. In this way, reliable triggering or opening can be made possible and / or damage to the connecting link or parts thereof can be prevented, since over-turning of the pivot lever can be excluded. The at least one stop element can be on the bearing housing of the base body and / or in the pivot bearing of the locking
    arranged device and / or by the guide link and
    Operational safety can be increased.
    In some embodiments of the invention, the locking device includes an optional separator. The closure part in its second, closed position, together with the base body, forms a belt chamber which can be separated into an upper belt chamber and a lower belt chamber by the separating element. This allows the connecting link to be permanently attached to the harness or a rope or belt strap.
    be done.
    In some embodiments of the invention, the separating element is arranged between the bore of the base body and the closure part. This feature has the effect that the height of the upper belt chamber can be reduced, so that the overall length of the connecting link is reduced without
    the length of the pivot lever of the locking device
    increasing pilots.
    In some embodiments of the invention, the end of the pivot lever opposite the pivot bearing can have a safety device which is designed to prevent inadvertent pivoting of the pivot lever. This further increases operational safety, as unintentional opening or loosening of the connecting link is avoided.
    will.
    In some embodiments of the invention, the securing device can contain a locking pin which is resiliently mounted on the pivot lever and engages in an associated bore on the base body. The safety device can be triggered in that the locking pin in its axial direction out of the bore of the base body.
    is pulled out.
    In some embodiments of the invention, the securing device can furthermore contain an actuating button in which the locking pin is received and which is axially displaceably received on the pivot lever. By target
    hen on the actuating button, the locking pin can thus in
    can be and the closure part is released.
    In some embodiments of the invention, the actuating button can have at least one first coiled contact surface and the pivot lever can have at least one second coiled contact surface which engages with the first coiled contact surface, so that by turning the actuating button it slides onto the first and second coiled contact surface and is thereby moved axially together with the locking pin attached to the actuation button. The user must therefore turn the actuating button to trigger or open the safety device in order to remove the locking pin from the bore on the base body in this way. Depending on the slope of the coiled contact surfaces, the angle of rotation of the actuating button required for this can be between approximately 20 ° and approximately 90 ° or between approximately 30 ° and approximately 50 °. This allows safe actuation and at the same time a reduced risk of unwanted
    Activity.
    In some embodiments of the invention, the actuator
    button in the form of a truncated cone. In
    In this case, the operating button does not have any undercut
    or between about 2.5 ° and about 5 °.
    In some embodiments of the invention, the connecting member furthermore contains a torsion spring which is designed to hold the securing device in the closed position and / or to move the securing device into a closed position. For this purpose, the torsion spring can exert a torque on the actuating button, so that it is rotated into its lower position by means of the first and second coiled contact surface, in which the locking pin is in
    the assigned hole engages on the base body.
    In other embodiments of the invention, the security includes
    approximately device of the connecting member a compression spring. The
    Compression spring applies a pressing force to the first and second
    pin engages in the associated hole on the base body.
    To trigger or open the connecting link, the user must therefore turn the actuating button against the spring force and then, after releasing the safety device, pivot the pivot lever in order to release the locking device of the closure part. This combined rotating / swiveling movement is on the one hand easy to carry out in stress reactions and on the other hand is so complex that it can be accidentally actuated, for example by objects getting stuck
    or body parts, is avoided.
    In some embodiments of the invention, a ramp can be arranged on the base body in front of the bore, on which the locking pin slides when the pivot lever is moved from the open to the closed position of the locking device. This enables fully automatic closing of the connecting link when the pivot lever is moved back into its closed position by a torsion spring, the locking pin on contact with the base body by sliding on the ramp against the force of the
    Compression spring is returned and then by the spring force
    engages.
    The connecting member according to the invention can be used, for example, to connect a parachute, a paraglider or a hang glider to part of the harness of a user of these devices. This ensures that the main parachute or the paraglider or the hang glider can be released quickly by the user if the user is out of control and the user is

    D- or C-shaped shape of the base body 10 results.
    The opening of the base body defined by the ends of the first and second legs 11 and 12 is closed by a movable closure part 4. On the first leg 11 there is a fork-shaped end 111 which, together with a bolt 115, forms a pivot bearing for the closure part 4. For this purpose, the closure part 4 has a bore at its first end 41 into which the bolt 115 engages. Furthermore, an optional first stop element 415 can be arranged at the first end 41 of the closure part 4, which opens the opening
    angle of the closure part 4 by bumping against the first
    is located.
    In some embodiments of the invention, a closing spring (not shown) can be arranged between the closure part 4 and the base body 10, which spring acts on the closure part in such a way that it is moved into its second position. This can facilitate the locking of the connecting link 1, since the second end 42 of the locking part 4 is guided against the locking device 3 and, by briefly opening the locking device 3, is brought into the completely closed position.
    locked position.
    The second end 42 of the closure part 4 opposite the first end 41 engages in a locking device 3 which is arranged at the distal end of the second leg 12. For this purpose, a bearing housing 121 can be arranged at the end of the second leg 12, which is set up to accommodate the pivot bearing 311 of the locking device 3, as will be explained in more detail below with reference to FIGS.
    is purified.
    be educated.
    The bearing housing 121 has a recess 125 through which the second end 42 of the closure part 4 can be inserted in order to move the closure part 4 from the first, open position into the second, closed position. Provided
    the locking device is closed, the
    ne unwanted opening of the connecting link is prevented.
    The closure part 4 in its second, closed position forms, together with the base body 10, a belt chamber which can be separated by an optional separating element 5 into an upper belt chamber and a lower belt chamber. This allows the connecting link to be captive on the harness or a
    Rope or webbing to be attached.
    If the separating element 5 is provided with a thread, this can be screwed in or out in a simple manner in order to assemble or disassemble the connecting element. As can be seen from FIG. 3, the separating element 5 is inserted through the second leg 12 from the side facing the pivot lever 3 and screwed into the opposite first leg 11. If the pivot lever 33 of the locking device 3 is in the closed position shown in the figures, it conceals the screw head at the same time, so that unintentional loosening of the separating
    element 5 is avoided.
    becomes possible.
    In the embodiment of the invention shown, the separating element 5 is arranged above the bore 17 of the base body 10, into which the locking pin 8 of a securing device engages. The separating element 5 is thus located on the side of the base body facing the closure part 4, i.e. the separating element 5 is arranged between the bore 17 of the base body 10 and the closure part 4. This feature has the effect that the height of the upper belt chamber can be reduced, so that the overall length of the connecting link is reduced without adversely affecting the length of the pivot lever 33. A short pivot lever requires higher actuation forces of the locking device 3 so that the triggering can no longer take place easily. At the same time, a short overall length is desirable. For the purpose of
    In the present description, the overall length is the distance
    the inside of the connecting web 15 and the inside of the
    Closing part 4 understood.
    FIG. 4 shows the locking device 3 as it is used in the connecting member shown in FIGS. 1, 2 and 3. The locking device 3 has a pivot lever 33 which is provided with a pivot bearing 311 at its first end 31. At the opposite, second end 32 there is a safety device which prevents unintentional actuation of the pivot lever
    or difficult.
    The pivot bearing 311 is received in the interior of the bearing housing 121 of the base body 10 so that it is rotatably supported there. For this purpose, the pivot bearing 311 can have a cylindrical or conical outer contour and the interior of the bearing housing 121 can have a complementary, likewise cylindrical or conical inner contour. The pivot bearing 311 has a recess 315 in its wall, which is designed to coincide with the recess 125 in the bearing housing 121 in a predeterminable position of the pivot lever 33, so that the second end 42 of the closure part 4 can be inserted and removed without any problems. If the pivot lever 33 is in the lower position shown in the figures, then
    the recess 125 in the bearing housing 121 through the wall of the
    Pivot bearing 311 blocked so that the locking device
    device holds the closure part 4 in the closed position.
    The angle of rotation of the pivot lever 33 is limited by a link guide 314, which is implemented in the form of a milled cut in the wall of the pivot bearing 311. The milling can limit the pivoting range to about 100 ° or about 90 ° or about 80 ° and is arranged such that in one end position the recess 315 with the recess 125 in the bearing housing
    121 coincides.
    A guide pin 6 engages in the link guide 314, which is pressed or screwed into the wall of the bearing housing 121. Alternatively or additionally, a second stop element 36 can be arranged opposite the housing 321 at the second end 32 of the pivot lever 33, which is supported on the second leg 12 and thus positions the pivot lever 33 in the closed position of the locking device so that the optional securing device described below intervenes reliably. A further stop, not shown in the figures, can also be present in the bearing housing 121, which adjusts the angle of rotation of the pivoting lever.
    bels 33 limited.
    In order to prevent unintentional opening of the connecting link, two safety mechanisms are provided in the embodiment shown. In other embodiments of the invention, one or both of the
    The security mechanisms shown do not apply.
    On the one hand, there is a return spring 71 in the pivot bearing, which is shown in FIG. The return spring 71 has a first leg 711 and a second leg 712. The first and second legs 711 and 712 are connected by several turns 715 of spring steel. The return spring 71 can be manufactured in one piece from a spring steel in a manner known per se. In the illustrated embodiment, the return spring has six turns. In other embodiments of the invention, the return spring can also have a greater or lesser number of turns. The first leg 711 comes to rest in the milled recess 313 of the pivot lever 33. The turns 715 of the return spring are received in the spring chamber 312 of the pivot lever 3. The second end 712 of the return spring is located in a pretensioned installation position inside the link guide 314. As the section according to FIG. 7 explains, this second end 712 of the return spring 71 is in an opening 65 on the end face
    the guide pin 6 added and so fixed.
    Locking device.
    FIGS. 1 and 3 also show that the spring chamber 312 is closed by an optional cover 7 which is fixed by a screw 72. In this way, the penetration of dirt, moisture and snow into the spring chamber 312 of the pivot lever 3 is avoided, so that malfunctions in rough ambient conditions, for example due to icing, can be avoided. The cover can also be made of a metal, an alloy or a polymer
    be.
    The return spring 71 has the effect that the pivot lever 33 is always moved back from an open position into the closed position shown in FIGS. 1 to 3. Even if the user accidentally actuates the pivot lever, it can automatically close again if the two recesses 315 and 125 have not yet been brought into alignment. Unintentional opening of the locking device due to vibrations can also be prevented, since the locking device is always closed in its closed position by the return spring 71 when the opening angle is small.
    is moved back.
    As an alternative or in addition, a securing device can be present at the second end 32 of the pivot lever 33 which contains a locking pin 8 which engages in an associated bore 17 on the base body 10. This is shown in Figure 3 in the closed position. To pivot the pivot lever 3, the locking pin 8 must first be moved out of the bore 17 on the base body 10 by moving it axially so that the pivot lever 3 can then be pivoted out into the open position. For this purpose it can be provided that the user applies a tensile force to one
    NEN actuation button 2 exercises.
    In order to facilitate this axial movement of the locking pin 8, it can be connected to an actuation button 2, for example by positively pressing it into a bore 22 of the actuation button 2. If the actuation button 2 has a smooth, slightly conical outer contour without undercuts, unintentional actuation is caused by Avoid getting caught, as straps, items of clothing or similar objects on the conical outer surface
    slide.
    In order to facilitate the axial movement of the locking pin 8 and the actuating button 2, second coiled contact surfaces 325 can be provided on the pivot lever 3 in some embodiments of the invention. As FIG. 5 shows, the actuating button 2 can also have a first coiled contact surface 25 in its interior 20. The first and second coiled contact surfaces 25 and 325 can have approximately the same slope. This feature has the effect that the actuating button 2 is moved axially when it is rotated by the user from its rest position shown in FIG. The user therefore does not have to apply a tensile force to the actuating button 2 which, under certain circumstances, leads to the movement of the entire connecting link and not to the axial release of the locking pin 8. Rather, the
    User turn the control knob, for example by more
    than 30 ° in order to reduce the axial movement of the locking pin
    initiate tes.
    As FIG. 3 further shows, an optional compression spring 9 can be present, which applies a tensile force to the actuation button 2 via the locking pin 8. Furthermore, the compression spring 9, which engages a contact surface 81 of the locking pin 8 and the pivot lever 33, guides the locking pin 8 into its extended, locked position, as shown in FIG. Thus, even an accidental brief rotation of the actuating button would not lead to the undesired opening of the connecting link, since the actuating button 2 and the locking pin 8 are rotated back to their original position by the compression spring 9, sliding inward on the first and second coiled contact surfaces 325 and 25 and with the bore 17 in engagement
    got.
    Figure 4 further shows that a housing 321 is formed at the second end 32 of the pivot lever 3, which is closed by the wall 21 of the actuating button 2 and inside the first and second coiled contact surfaces 25 and 325 and the torsion spring 9 also against moisture and Contamination are arranged protected. A hole 322
    leaves the passage of the locking pin 8. Thus, can
    be arranged protected on the link.
    Figure 8 shows the pivot bearing with return spring according to a second embodiment. The same components of the invention are provided with the same reference symbols, so that the following description focuses on the essential differences
    limited.
    As FIG. 8 shows, a third stop element 124 is attached to the bearing housing 121 at the end of the second leg 12 and is manufactured in one piece with the base body 10 of the connecting link 1 as a forged part. The third stop element 124 projects laterally beyond the plane defined by the movement of the pivot lever 33 and thus forms a stop for the pivot lever 33. This has the effect that the pivot lever 33 cannot be moved beyond the open position in which the recess 315 of the Locking device and the recess 125 in the bearing housing 121
    stand on top of each other and release the closure part 4.
    The third stop element 124 also has a bore or notch, which is covered in FIG. 8 and therefore not visible, into which the first end 711 of the return spring
    71 intervenes. This makes assembly particularly easy
    33 to enable.
    Of course, the invention is not limited to the embodiments shown. The above description is therefore not to be regarded as restrictive but rather as explanatory. The following claims are to be understood in such a way that a named feature is present in at least one embodiment of the invention. This does not exclude the presence of further features. If the claims and the preceding description define “first” and “second” embodiments, this designation serves to distinguish between two similar embodiments, without one
    Establish precedence.
