Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a separate type one-touch clasp.

0002

[Conventional technology]

This type of separate type middle clasp is described in Japanese Utility Model Publication No. 1-26255. Applicable The publication describes one half of the metal fitting formed by passing a hanging scroll across the tip of the U-shaped member, and the U-shaped member and the lower side. The other half of the fitting, which consists of a member and a lid, is described.

0003

[Problem that the idea aims to solve]

However, the latch claw provided vertically on the lid body of the above publication presses against the protrusion provided on the lower member. Because the metal fittings are latched together, it is not easy to unlatch and separate the metal fittings. There was an issue.

0004

[Means to solve the problem]

In this invention, a rotating part is provided at the tip of the frame metal fittings and the base member, and the opening/closing plate is attached rotatably. In a separate type clasp for a watch band consisting of a hanging metal fitting, A push button is provided on one side or both sides of the base member of the hanging metal fitting, and a push button is provided next to the push button. A latching part that slides to open and close is provided, and a latching part that is attached to and detached from the latching part is provided on the opening/closing plate. A claw is provided, and a tension spring that flips up the opening/closing plate when the locking claw is released is used to rotate the opening/closing plate. The present invention is intended to solve this problem by providing it in the section.

[0005]

【Example】

Examples will be described below based on the drawings.

[0006] As can be seen in FIG. 4, the frame fitting 2 shown in FIG. It is formed by passing the shaft member 2d across, and the base ends of the side plates 2b and 2c are connected to the ends of one and a half watch bands 1a. This is done by fitting it into the shaft and attaching it to the shaft. 2a is for inserting and removing the opening/closing plate 6 of the hanging bracket 3, which will be described later. This is a framework for understanding.

[0007] Attach the hook 3 to one end of the other half of the watch band 1b. The hook 3 is shown in Figure 4. It consists of a base member 4 and an opening/closing plate 6 rotatably attached to the tip of the base member 4. ing.

[0008] As shown in FIG. 5, the base member 4 consists of one half of the bottom plate 11, which has a cylindrical part 5 for attachment at the tip. By bending, a rectangular tube part 12 with a window hole 12a provided in the middle of the upper surface is formed on the bottom plate 11, and this is The base end of the frame member 13 is surrounded by a U-shaped frame member 13 having an opening in the watch band 1b. The push buttons 7a, 7b protrudes, and a square shaft member 9a, which is provided with a hooking part 8 at the tip following the buttons 7a, 7b; 9b is housed in the square tube part 12, a spring bar 10 is stretched between the square shaft members 9a and 9b, and the hooking part 8 This portion is located below the window hole 12a. The latching part 8 is designed to prevent the latching pawl 15 (described later) from slipping. The upper surface is a circular curved surface and the lower surface of the curved surface is recessed into a hook shape so that it can be inserted and locked. do. In FIG. 5, 14 is a notch provided at both ends of the square tube part 12, and the square shaft member 9a, After housing the square shaft members 9b, the square shaft members 9a and 9b are folded in to prevent the square shaft members 9a and 9b from being pulled out.

[0009] A cylindrical portion 6b provided on the spring plate 17 integrated with the opening/closing plate 6 is attached to the cylindrical portion 5 for attachment at the tip of the bottom plate 11. Engage and lock shaft 5a.

0010 As shown in FIG. 4, the spring plate 17 is fitted onto a step surface 6a provided at the middle of the inner surface of the opening/closing plate 6. A leaf spring with a hook 15 bent at the tip and a leaf spring for flipping up the opening/closing plate 6 on the base side. Notches 16 are formed.

[0011] Therefore, the one-touch clasp of the separate type according to the present invention has the opening/closing plate 6 of the hanging metal fitting 3. It is attached and detached by going in and out from the frame 2a of the frame fitting 2, and in the connected state shown in Fig. 1. When the push buttons 7a and 7b are pressed, the spring bar 10 is compressed and the square shaft members 9a and 9b are moved toward each other. Since the latch portion 8 at the inner end is opened and moved, the latch claw 15 is unlatched. Ru. Then, the spring leaf spring 16, which was in pressure contact with the four sides of the base member due to the latch, springs up. to flip up the opening/closing plate 6 to the solid line position in Figure 3, so use the same finger that pressed it to open it. This means that the closing plate 6 can be changed and expanded in the direction of the temporary line position.

0012 Figure 6 shows an example in which a leaf spring 16 for flip-up is separately formed and assembled to the opening/closing plate 6. There is.

[0013] Figures 7 to 8 show examples in which square shaft members 9a and 9b are assembled in series with a spring bar 10 in between. Then, one end of the bottom plate 11 is wrapped and fixed around the transition plate 4a of the base member 4. 18 is a fitting plate with square shaft part This is to support the members 9a and 9b. In addition, in Figures 9 and 10, push button 7 is An example is shown in which one square shaft member is assembled so as to protrude only on one side. this place In this case, the latching portion 8 and the latching claw 15 will be provided only on one side.

[0014] In Figures 11 and below, two long holes 19 are provided in the bottom plate 11, and the bottom surfaces of the square shaft members 9a and 9b are inserted into the long holes 19. Insert the screws or press-fit pins 20 that are attached to the Figure 15 shows a leaf spring that prevents the opening and closing plate 6 from coming out and also flips up the opening/closing plate 6. In the case of the coil spring 16a, the coil spring 16b surrounded by a tube, and the extension of both ends of the tube with ends, An example is shown in which one of the leaf springs 16c, which has a wing for lifting, is selected and inserted into the shaft 5a. are doing.

[0015] In this way, the coil spring 16a etc. are attached to the shaft 5a and both ends are attached to the opening/closing plate 6 and the bottom plate 11. If it is straddled, the opening/closing plate 6 will move to the temporary position shown in Figure 3 when the latch claw 15 is released. It will be lifted up to the line position.

[0016]

[Effect of the idea]

As described above, the present invention provides a separate type of clasp with the base of the hanging member. A push button is provided on both sides or one side of the member, and the end of the square shaft member following the push button is A latching part that moves to open and close is provided in the opening and closing part so that it can be attached to and removed from the latching claw on the opening/closing plate. The effect is that the hanging and unhooking can be done quickly and reliably with one touch. Also , Since a tension spring for flipping up the rotating part of the opening/closing plate is attached, the latch claw can be unlatched. The effect is that when the opening/closing plate is lifted up, it can be immediately pulled out from the frame metal fittings. produce fruit.
