DE3509643C1 - Buckle for jewelry chains, bracelets, belts and other clothing - Google Patents

Description

The invention relates to a snap fastener for jewelry chains, bracelets, belts and other items of clothing.

According to CH-PS 4 30 299, such a plug-in closure is known in which the one designed as a closure cone Plug head penetrates a resilient locking sleeve arranged in the socket, on the free spring ends he is based on guard locking and on the plug pin between the locking cone and a stop a movable ring is provided. The locking ring above must be used to release the lock inserted with two fingertips and with two fingers of the other hand at the same time Be pulled out. This requires special manual dexterity, and the smaller the smaller it is the closure is such. B. with jewelry chains.

Furthermore, according to US-PS 14 14 838 such a plug closure is known in which the plug head as Spreading spring cap is formed, the springs of which are supported against a stop ring for closure and a movable ring is provided in the socket for releasing the closure. This must be done at the same time Train the plug a ring cap to bring the spread plug spring ends together, which when inserting, grip behind a ring stop and press in to open the lock.

Such handling is cumbersome. The pull-out plug itself must also be made of spring material exist and cannot be made of noble on the visible part

be made of metal.

It is now the object of the invention to provide a plug fastener, which is easy by renewed Plug-in movement is to be opened and all visible parts are made of precious metal as jewelry clasps could be.

This object is achieved in the plug closure according to the invention according to the preamble of claim 1 solved that when the plug is pushed in further beyond the closed position, the springs of the Closure sleeve can be expanded by means of a retracting ring to release the closure cone, with the ring clamp and the ring of the locking cone which is flush with it when the plug is pulled out can be pushed out of this bracket to the closure opening.

According to a further concept of the invention, this object can also be achieved with a plug-in closure according to the preamble of claim 2, characterized in that when the plug is pushed in further Beyond the closed position, the springs of the expanding spring cap can be compressed to release them from the ring are, whereby they clamp the ring and allow the expansion spring cap to be pulled out of the socket.

A preferred embodiment is in each case for both embodiments of plug-in closures according to the invention shown in the drawing schematically in longitudinal section, namely show

F i g. 1 shows a plug and a socket of a first embodiment of the closure of the invention Start of the insertion process,

F i g. 2 the plug and the socket after the closure produced by the plugging movement,

Fig. 3 the plug and the socket after renewed plugging movement by axial pressure on the plug,

F i g. 4 the plug and the socket when pulling out the plug after opening the lock,

F i g. 5 shows a plug and a socket of a second embodiment of the closure of the invention Start of the insertion process,

F i g. 6 the plug and the socket after the closure produced by the plugging movement,

F i g. 7 the plug and the socket after renewed plugging movement by axial pressure on the plug and

F i g. 8 the plug and the socket when pulling out the plug after opening the lock.

In the embodiment according to FIG. 1 to F i g. 4, the plug 26 with the holding shaft 7 is inserted into the socket 2. The socket 2 comprises a resilient locking sleeve 3. When the plug 6 is inserted, the locking cone opens 4, which sits at the end of the guide pin 9, the locking sleeve 3, which closes again behind him (Fig. 2) and so produces the closure. It cannot be opened by pulling on the holding shaft 7.

Rather, to open the plug 6 must be pushed in further. He then pushes the opening ring 5 into the spring sleeve 3 and opens it (FIG. 3). At the Withdrawing the plug 6, the ring 5 remains clamped in the spring sleeve 3 (FIG. 4) until it, from the cone 4 taken, is drawn into the interior of the sleeve 3. The shutter is now open.

In the embodiment according to Fig.5-8 carries the Guide pin 9 an expanding spring cap 10. The socket 2 has two stop rings 11 and 12 on the inside, between which a ring 5 is freely movable. When inserting the stop ring 12 presses the springs of the cap 10 together, its front part enters the ring 5 and pushes it

against the stop ring 11. After the springs of the cap 10 have passed the stop ring 12, spread they move and are supported against the inner surface of the stop ring 12 (FIG. 6). The lock is made and cannot be released 5 by pulling on the holding shaft 7.

Rather, to release the lock, the plug 6 has to be pushed further into the socket 2. the Springs of the cap 10 are now compressed 10 by the ring 5 resting against the stop ring 11 (F i g. 7) and thereby clamp the cap 10 on the ring 5 at the same time, so that the springs are now at Pulling out the plug 6 can pass the stop ring 12 (Fig. 8). When you take off the Ring 5 retained by the stop 12, while 15, the cap 10 from the ring 5 and the plug 6 from the Socket 2 is pulled out. The lock is released.

Claims (2)

Patent claims: 1. Plug closure consisting of a plug and a socket for jewelry chains, bracelets, Belts and other items of clothing, in which the plug head designed as a locking cone has an in the bushing arranged resilient locking sleeve penetrates, on the free spring ends of which he is to Guard locking is supported and a movable one on the plug pin between the locking cone and a stop Ring is provided, characterized in that when the plug (6, 7) is pushed in further over the closed position (Fig. 2), the springs of the locking sleeve (3) can be expanded by means of a retracting ring (5) to release the closure cone (4), thereby removing the ring (5) clamp (Fig. 3) and the ring (5) from which it is flush when the plug (6,7) is pulled out Closure cone (4) (Fig. 4) can be pushed out of this clamp to the closure opening. 2. Plug closure consisting of a plug and a socket for jewelry chains, bracelets, Belts and other items of clothing in which the plug head is designed as an expanding spring cap, the springs of which are supported against a stop ring for closure and a movable one in the socket Ring for releasing the lock is provided, characterized in that upon further pressing of the plug (6, 7) beyond the closed position (Fig. 6), the springs of the expanding spring cap (10) are compressible to release them from the ring (5), whereby they clamp the ring (5) (Fig. 7) and allow the expansion spring cap (10) to be pulled out of the socket.
