"Folding clasp for watch straps"

The innovation relates to a folding clasp for watch straps.

In the case of the known folding closures, “the bottom element with a hinged first strap end is interposed by means of an interposed one Folding member hinged on the one hand to the cover member, while the cover member on the other hand an extendable member with articulated takes up the second end of the tape in the closed position, with the cover and extension link by hasting to adjust the width interact with each other.

It is important with such closures that they are next to the unfolding for slipping on the bracelet with wristwatch on the Hand as well as the level setting for adjustment on the arm also have a certain flexibility to accommodate the movements on the arm to be able to give in to the wearer.

The folding clasp for watch straps of the ones described above
According to the innovation, type is characterized in that
A box member can be moved across the lid member,
which engages adjustably with emerging spring catches on the) o-kelrasten, which box member is preferably also used to accommodate a spring member, whereby both the step setting and the desired elasticity is achieved on the one hand.

In detail, a spring clip can be articulated in the box member retracted into the cover member, which provides lateral spring catches and interacts with side catches on the cover member, the spring clip being moved by means of incised spring tabs
Box member is supported and with its spring catch ...;. ', Held in a hasty position in the cover member, while in the box member on the other hand, the spring catches a frame member can be extended against spring action, to which the second tape end is hinged, while the first is hinged to the bottom member.

An embodiment of the folding closure according to the furnace
is shown in the drawing, for example:

F i g. 1 the section through such a folding clasp "while closing,

i ¹ ig. 2 shows the section through the novel snap-in and spring box for FIG. 1,

F i g. 3 clie view of the spring clip to FIGS. 2 and

F i g. 4 shows the rear view of the open folding clasp Fig. 1.

As can be seen from the drawing, especially in Fig. 1, the folding lock consists of the cover member 1 with a bottom member 3 hinged on the one hand via a folding member 2 to which one end of the tape ^L \ - is hinged, while on the other hand in the cover member 1 the latching and Spring box 5 can be pushed in for step adjustment and is provided with an extendable frame member 6 with inserted spring 7 for stretching and on. the second band end 8 is hinged to this frame member. For the step adjustment, a spring clip 9 is articulated approximately in the middle in the box member 5, which provides with lateral spring catches 10 and with the side catches 11 on the encompassing cover member I

cooperates. The spring clip 9 has an incised spring tab 12 with which it is located in the box member 5 2 and held with its spring catches 10 in the catch position in the side catches 11 in the cover member 1 is. Between the spring catches emerging from the box section 5 the spring clip 9 has a push handle 13 for disengaging Veitenverstellung in the cover member 1 in direction A corresponds to Fig., While the locking through sliding roof-k in the opposite direction as a result of the respective bevel on the spring catches 10 without depressing the pressure handle 1j5 corresponding to FIG. 1 takes place like a catch. In the extendable frame member 6, the spring 7 lies between raised end walls 14, 15 on the box and frame member 5 »6 accordingly Fig. 2, so that the latter (6), i.e. the band part 8 can rebound in direction B.

In addition, the box member 5 is for better insertion on Lid member 1 with the clasp and bracelet underneath the spring catch 10 extended at 16 or the box member 5 has stop cams 17, which are used for Ausfahrbegrenzxing interact with end tabs 18 on the latching strips ″ 11 on both sides of the cover member 1, as FIG. 4 shows.
