DE7906754U1 - FOLDING CLOSURE FOR WATCH STRAP - Google Patents

Description

Description:

The innovation relates to a folding clasp for watch straps with cover member and bottom member articulated by means of a folding member, to which one end of the tape can be attached, while the second end of the tape is to be attached to the detent adjustable extension member of the cover member, the detent adjustment by means of Pushers of a detent spring can be triggered, which folding lock is provided with a latch between the folding base and the cover member.

According to DE-GM 75 07 948, the one with notches on the extension member is closed; « interacting locking spring inserted in the cover member and esp. |

through on the hinge for the folding link with hinged leaf spring | forms and that in U-shape, with their locking lugs on one or ψ on both sides lock with the extension member and by means of one or |

levers provided on both sides can be actuated. |

In the known folding lock designs, the latching takes place between Folding base and cover member by means of the articulation point .. '; from the folding member encompassing the bottom end flap, which latching can jump open when there is strong arm movement and pulling. It is now the task of the innovation here to provide an additional locking mechanism to reach.

The folding clasp according to the preamble of the protection claim is characterized by a double latching by means of a die
Articulation point of the folding link encompassing the bottom end flap as well
a for this purpose set back and inclined closure flap on the bottom, which when closing in a hole on the
Folding member engages and is held in the same way as a band pull ^ .Iderhakenartig and thereby provides a perfect protection against unintentional opening. Unintentional opening is reliably avoided by the additional locking tabs on the bottom that claw into the perforation on the folding element when the tape tension occurs, whereas opening of the lock in the usual way is avoided
simply leave it by pivoting the cover member against the direction of tension of the tape. In an advantageous manner, the bottom end flap has an S-shape for gripping around the articulation point of the folding member for easier closure.

In the case of folding clasps with an extendable folding link for
the hinged bottom link, whereby the folding link consists of a frame link with an extendable link plate and is positioned against the end delimitation by means of cut-out, opposing end tabs on the frame leg, the frame end can run into two angled sockets and the cut-out, opposing end tabs have a T-shape and

be solvable. This allows the enlarged by T-shape Elasticity also means that the connected link strap is opened to hang up the watch with the bracelet and to send it to you open slightly, for which the T-bar is preferably to be pressed down

is corrugated by means of a thumbnail.

A preferred embodiment of the development of the folding lock according to the innovation is shown for example in the drawing and described below, namely show:

F i g. 4 the rear view in the open state.

As can be seen from the drawing, the folding closure consists of the cover member 1 and by means of an extendable one here Folding member 2 hinged bottom member 3, to which then one tape end 4 4 is to be attached, while the second tape end 5 is attached to the detent adjustable extension member 6 of the cover member. The locking adjustment is carried out by means of one or both

provided pushers 7 of a locking spring 8, which by means of locking lugs 9 cooperates with notches 10 from the extension member 6. Here, according to FIG. 4, the detent spring 8 is in the form of a U-shaped Leaf spring with latches 9 on both sides and pushers 7 inserted in cover member 1 and on the one hand on hinge 11 for the folding member 2 and also serves as an extension limiter by means of a flap stop 6a for the extension element 6.

According to the innovation, the closure is carried out by double locking by means of one that encompasses the articulation point 11 of the folding member 2 Bottom flap 3a, which has an S-shape for easier closure according to FIG engages in a perforation 2c on the folding member 2, this (3b) being held like a barb in the same (2c) when the tape tension occurs is and thereby a perfect protection against unintentional opening results, on the other hand opening the lock in the usual Way simply remains by pivoting the cover member against the direction of pulling the tape.

As can be seen particularly from Fig. 4, there is the extendable Folding member 2 from a frame member 2a with an extendable link plate 2b, the cut-out end tabs 12 of the T-shape The extension limit on the frame leg is used and when pressing down on the corrugated T-bar 12a for separating the closure and
