Definitions

• the invention relates to a keychain with a bow-shaped support body with two legs, the opening of which can be closed and released by means of a locking body which can be locked with the legs.
• a key fob of this type is known from US-PS 31 26 729.
• the closure body is designed as a disc, which has two insertion openings for the legs of the support body. Each leg is locked in two places along its longitudinal dimension with the closure body.
• the support body To insert a key, the support body must be completely detached from the lock body.
• the key fob in the open position consists of two separate parts, one of which can be lost.
• the security against unintentional loosening of the closed position is not particularly great, since both parts are also released from one another in the same direction in which the latching connections are released. Once the rest connections have been broken, then the closure body can be easily detached from the support body.
• closure body is arranged between the legs running parallel to one another, the end of the closure body facing away from the opening of the support body being slowly adjustable on the legs by means of two rings rotatably mounted in the closure body and being pivotable about this axis of rotation that the closure body can be locked at least in the end region facing the opening of the support body with the legs transversely to their longitudinal direction and that one leg extends beyond the free end of the other leg and is designed as a stop for the ring guided on this leg.
• the closure body is held captively on the stop on a Sche's captive on the support body. Is the snap connection solved, which must be perpendicular to the longitudinal direction of the legs, then the closure body must be adjusted in the longitudinal direction of the legs to the stop to release the opening. Then the closure body must be tilted so that the other ring is released from the other leg. Once this canting has been carried out, the closure body must still be turned, the leg with the stop and the ring guided thereon forming the pivot bearing. Only then is the opening of the support body released. These lined up movements of the closure body in different directions provide great security against unintentional release of the opening of the support body.
• the closure body in the end region facing the opening has a pressure piece which is designed as a flat cuboid and is provided on the end faces facing the legs with grooves which are circular in cross section and into which the cross sections are rounded Snap the legs of the support body into place.
• the guidance and the adjustment path of the closure body on the legs of the supporting body are ensured in that the length of the closure body corresponds approximately to the length of the legs and that the distance between the central axes of the rings from one another corresponds to the distance between the longitudinal central axes of the legs, and that the closure body is narrower than the clear distance between the legs of the support body and that the distance between the two grooves is slightly larger than the clear distance between the legs.
• the locking of the closure body on the support body in the closed position can be further improved in that the pressure piece is provided with additional locking receptacles into which the free ends of the legs snap.
• a structural design for the stop with additional latching is characterized in that the free end of a leg is bent inwards and forms the stop, that the closure body carries an L-shaped piece in the end region facing the opening of the support body, the cross section of which is approximately that Cross section of the legs corresponds, and that in the closed position, the end faces of the piece designed as locking receptacles are locked with the ends of the legs.
• the rotary mounting of the rings in the closure body is achieved in a simple manner in that the closure body consists of two flat parallelepiped sections connected by rivets, between which the pressure body and the rings connected by means of a connecting piece are arranged.
• the support body has the shape of an open ring that ends in the two legs.
• the support body and / or the closure body consist of an elastically deformable material.
• FIG. 8 shows the closure body of the key fob according to FIG. 6.
• a key fob which consists of a bent lf örmi gene supporting body 10 with two legs 11 and 12, between which a closure body 16 can be inserted and detachably connected to the legs 11 and 12.
• the legs 11 and 12 run approximately parallel to one another and the width d 1 of the closure body 16 is somewhat larger in the open position of the key fob than the distance d 2 of the legs 11 and 12 from one another.
• the legs 11 and 12 are elastically deformable.
• the closure body 16 has a pressure body 18 extending transversely to the legs 11 and 12, the end faces 20 and 21 facing the legs 11 and 12 of which have recesses 23 and 24 which are complementary to the sections of the legs which can be connected to the pressure body 18.
• the cross section of the legs 11 and 12 is circular.
• the pressure body 18 is a flat cuboid carried by the closure body 16, the end faces 20 and 21 of which are in pressure connection with the legs 11 and 12 and made of grooves 23 and 24 which are circular in cross-section (see FIG. 4) are formed.
• the closure body 16 is also formed as a flat cuboid.
• the length of the closure body 16 corresponds approximately to the length of the legs 11 and 12.
• the inner diameter of the rings 30 and 31 corresponds to that
• the distance d 3 of the axes of the rings 30 and 31 from one another corresponds to the distance d4 of the longitudinal central axes of the legs 11 and 12.
• the free end of the leg 12 has a stop 33, here a collar, which is larger than the inner diameter of the rings 30 and 31.
• FIG. 3 in particular shows that the two legs 11 and 12 have different lengths , wherein the length of the leg 11 is approximately shorter by the thickness of the stop 33.
• the closure body 16 consists of two F rachquaderabschni connected by rivets 40 and 41, between which a separate pressure body 18 and by means of a connecting piece 44, here a shaft (Fig. 5) connected rings 30 and 31 are arranged. It can be seen that the support body 10 has the shape of an open ring which ends in the two legs 11 and 12. The support body 10 consists of an elastically deformable material, while the closure body 16 is not deformable.
• the support body 10 shown in Fig. 3 is connected to the closure body 16 so that it assumes the position shown in Fig. 2.
• the leg 11 is threaded into the ring 31 and the ring 31 is moved up to the stop 33.
• the keys are then hung in the key chain.
• the leg 11 is inserted into the ring 30.
• the rings 30 and 31 are guided along the legs 11 and 12 to the widening bracket until the closure body 16 is arranged between the legs 11 and 12 so that the pressure body 18 can be snapped onto the legs behind the stop 33.
• Pressure is exerted on the closure body 16 until the pressure body 18 snaps between the two legs 11 and 12.
• the closure body 16 is arranged immovably between the legs 11 and 12, since it is supported on the one hand at the stop 33 via the pressure body 18 and on the other hand via the rings 30 and 31 at the transition between the legs 11 and 12 and the bracket.
• the closure body 16 takes the position shown in Fig. 1. It is connected to the support body 10 so that the key 8 is captively connected to the key fob.
• a key 8 is now to be detached from the key fob, then pressure is exerted on the closure body 16 in the region of the pressure body 18, namely in the direction of the rivet 41.
• the pressure increases the distance between the legs 11 and 12, so that the one end of the closure body 16 releases from the legs 11 and 12.
• the closure body 16 is rotatably connected to the shaft 44 of the rings 30 and 31 so that it can be pivoted about the axis of the shaft 44. Then the ring 30 connected to the shorter leg 11 is detached from the support body 10 so that the key ring can assume the position shown in FIG. 2. This enables the key 8 to be detached from the key fob.
• FIGS. 6, 7 and 8 reveal a further embodiment of the key fob.
• both the legs 54 and 55 and the closure body 16 are partially designed differently.
• the free end 50 of the longer leg 54 is bent towards the shorter leg 55 as a stop, while the closure body 16 carries a piece 57 which, when the key fob (FIG. 6) is in the active state, lies or is clamped between the two legs 54 and 55 and is flush with them.
• the end faces 58 and 59 of the piece are convexly curved and project into the concave recesses of the ends 50 and 51 when the key fob is assembled (FIG. 6). It is therefore a form-fitting locking connection between the piece 57 and the longer or shorter legs 54 and 55.
