Description

[Detailed description of the invention] <Industrial application field> This invention relates to a clasp fitting for a watch band.

<Problems that this invention aims to solve> Conventionally, a pin for hanging and unloading was provided at the tip of the U-shaped frame of one metal fitting, and the lid body and the latching member were pivotally attached to the U-shaped frame of the other metal fitting. The clasp fittings are well-known and issued by the Japan Patent Office.
It is described on pages 163 to 166 of the collection of commonly used techniques (non-metallic watch bands), but for the middle clasp described in the collection of techniques, the lid body must be passed through the inside of the locking pin from the back side and then returned in the return direction. It is extremely troublesome to operate as you have to fold it down to hang it and untie it by reversing the process.
I had some problems with my watch, including dropping it and damaging it on the way. Further, there was a problem in that the latching member rotated around the pinned portion, making opening and closing operations difficult. The present invention attempts to solve such problems.

<Structure of the device> This device consists of one metal fitting and the other metal fitting. One metal fitting is formed by horizontally suspending a pin for hooking and removing from the tip inside the first U-shaped frame, and the other metal fitting is A hanging member is attached with a pin in a second U-shaped frame so as to partially protrude forward, and the hanging pin is attached to and removed from the middle of the hanging member. A groove is provided, a recess is provided at the base of the latching member, and a pressing pawl is pivoted in the recess and fits into the latching/detaching groove, and the opening/closing device rotatably covers the latching member. A watch characterized in that a lid is provided, and a rotation regulating plate is provided below the middle of the lower surface of the latching member, and the end of the rotation regulating plate is opposed to the lower front end surface of the second U-shaped frame. It's on the middle clasp of the band.

<Example> Examples will be described below based on the drawings.

1 to 5 show an embodiment of a women's watch band in which a cylindrical shaft member and a spherical member are alternately connected, and watch bands 3a and 3b are formed by alternately connecting a cylindrical shaft member 1 and a spherical member 2. One metal fitting 4 and the other metal fitting 5 are attached to the respective ends of the metal fittings 4 and 5. One metal fitting 5 is attached to the tip of the first U-shaped frame 17 with a pin 1 for hooking and removing.
8 is horizontally suspended, and the other metal fitting 4 is attached to the second U-shaped frame 6 with a pin 8 so that a part of the metal fitting 4 protrudes forward, and the locking member 7 is A bag groove 9 with an open upper surface is formed transversely in a portion projecting forward outside the frame. The blind groove 9 is formed by expanding the aforementioned semicircular groove 9a in the lower half. A concave portion 10 is provided on the base side of the hooking member 7, and a proximal convex portion 12 of the lid body 11 is fitted into the concave portion 10 and fixed with a pin 13, so that the lid body 11 can be freely rotated to open and close. The lid body 11 has a latch claw 14 on the inner surface of the tip portion thereof, which is hooked to and detached from the front end surface 7a of the latch member 7, and a push claw 15 that fits into the bag groove 9 on the inner surface of the intermediate portion. Note that reference numeral 16 denotes a rotation regulating plate provided on the lower surface of the intermediate part of the latching member 7, which protrudes in the lateral direction and has an end opposed to the lower surface of the front end of the second U-shaped frame.

When connecting the two metal fittings 4 and 5, the pin 18 for attaching and detaching the metal fitting 5 of one metal fitting 5 is inserted into the top-open bag groove 9 provided in the other metal fitting 4, and pulled toward the semicircular groove 9a side. The lid 11 is folded down and rotated. Then, the latching claw 14 engages the distal end surface 7a of the latching member 7, and the pushing claw 15 enters the pocket groove 9 and presses a part of the pin 18 to fix the pin 18, and both metal fittings are fixed. 4,5
It will connect the two.

When the connection between the metal fittings is released, the lid body 11 is moved upwardly and unfolded against the latch. Then, the pusher claw 15 is removed from the pocket groove 9, so the pin 18 can be freely pulled out and the connection between the metal fittings is released.

FIG. 6 shows an embodiment of a men's watch band, which is exactly the same as the previous example except that the watch bands 19a, 19b and each member are made wider.

<Effects of the invention> Since the present invention is constructed as described above, the locking pin of this kind of middle clasp provided on one of the metal fittings is inserted from above into the bag groove provided on the other metal fitting, and the lid body is closed. An excellent effect is produced in that the connection can be made by an extremely simple operation of folding down the lid, and the connection can be released by moving the lid upward and removing the locking pin.

In addition, since a rotation regulating plate was provided under the middle of the latching member of the other metal fitting and opposed to the bottom of the front end of the second U-shaped frame, rotation of the latching member was regulated regardless of whether it was pinned or not. Since it maintains almost the same plane as the two-frame frame, it has the effect of smoothing the insertion and removal of the hooking pin into and out of the bag groove and the rotation of the lid body, making connection and disconnection operations extremely easy. arise.
