Abstract

(57) [Abstract] [Purpose] The present invention aims to provide a wrist watch band that can be easily attached to and removed from a watch case by anyone without using a specialized tool or the like. It is a thing. According to the present invention, a folding portion 2 is provided at an end portion of a band 1, and a leaf spring member 3 formed in two folds for elastically opening and closing the folding portion 2 is inserted into the folding portion 2 and the folding portion 2 is formed. In a wristwatch band in which the band 1 is attached to and detached from the spring rod 4 of the watch case 6 by opening and closing, the leaf spring member 3 includes the flat upper piece 3a and the gently curved lower piece 3b. In the wristwatch band, one or a plurality of closing push pieces 5 are formed in the middle of the upper piece 3a or the lower piece 3b.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wristwatch band, and more particularly to a wristwatch band that anyone can easily and easily attach to and detach from the watch case with one touch.

[0002]

[Prior art]

 A technique of this kind is disclosed in Japanese Utility Model Publication No. 37-12493. This publication discloses a wristwatch band in which upper and lower pieces are sewn together on the abdomen, and hooked metal fittings are attached to both ends of a spring rod that extends over a watch earring, and a bag portion is formed at both outer ends of the band. In addition, the outer end of each upper piece is extended longer than the outer end of the lower piece, and the part of the nearly convex elastic thin plate near the tip is bent to form a tubular part, and the tip is aligned with the substrate. Elastically intimately, and the tip of the hook is bent slightly in the opposite direction, and the base of the hooking metal is inserted into the bag and attached, and the outer surface of the upper piece is covered and covered. It also describes the structure that is attached.

[0003]

[Problems to be solved by the device]

 However, since the hook fitting of this publication has a tubular portion with a closed inlet, the spring rod can enter the tubular portion when the band is inserted and removed so that the width of the spring rod can pass through the inlet of the tubular portion. There is a problem that the tip part loses its resilience and does not return and close when opened and closed once or twice. In addition, since the tip edge is bent in the opening direction, there was a problem that it hits the skin strongly and causes discomfort.

[0004]

[Means for Solving the Problems]

 According to the present invention, the leaf spring member 3 is formed by folding the flat upper piece 3a and the gently curved lower piece 3b into two pieces, and one closing pressing piece 5 is provided between the upper piece 3a and the lower piece 3b. It is intended to solve such a problem by providing a plurality of or a plurality of them.

[0005]

[Action]

 The folded part of the band of the present invention has a gentle curved shape at the folded end which is the lower side due to the shape of the leaf spring member to be inserted, and therefore, the folded end allows the spring rod to be taken in and out with a small expansion. Therefore, even if the opening / closing operation for attachment / detachment with the watch case is repeated, the return portion does not attenuate the return closing pressure. Further, since the pressing piece for opening and closing is provided in the middle of the upper piece or the lower piece of the leaf spring member, the band does not fall off from the watch case. Moreover, since the folded end is slightly opened by the push piece, it is easy to hook the finger for opening and closing.

[0006]

【Example】

 Embodiments will be described below with reference to the drawings.

The folding portion 2 is provided at the end of the leather band 1, and the leaf spring member 3 which is folded in two inside the folding portion 2 is wrapped and inserted. The upper piece 3a of the leaf spring member 3 is flat and the lower piece 3b has a gently curved shape. Reference numeral 5a is a V-shaped notch-shaped pressing piece provided on the lower piece 3b of the leaf spring member 3, and one is provided at the middle or one at the side as shown by a and b in FIG. Further, FIG. 4 shows an example in which two inward projecting push pieces 5b are arranged in parallel.

The V-shaped notch type pushing piece 5a or the inward projecting type pushing piece 5b is pressed against the upper piece 3b of the leaf spring member 3 or directly against the lining leather covering the upper piece 3b and then folded back. In addition to closing the part, the tip 2a of the folded-back part 2 is slightly lifted open to form a finger-holding gap.

When attaching the leather band 1 to the watch case 6, a finger is applied to the tip 2a of the folded portion 2 to close the space between the upper piece 3a and the lower piece 3b and open against the pressure to open the spring rod 4 of the watch case 6. The spring bar 4 on the inner surface of the base end of the folded portion 2, and when removing the leather band 1, push it in the opposite direction because the folded portion 2 has a gently curved shape. The leather band 1 can be pulled out only by moving the pushing piece 5a or 5b so as to get over the spring rod 4, and it is not necessary to open the tip 2a of the folded portion 2.

[0010]

[Effect of device]

 Since the present invention is configured as described above, anyone can easily attach and detach the watch band with one touch by opening the folded portion against the watch case and closing it against pressure. Produce an effect.

According to the shape of the leaf spring member to be inserted and attached, the folded-back portion of the present invention has a gentle curved surface at the folded-back end portion. Therefore, the folded-back end portion has a narrow wide expansion to open the spring rod. Since it can be put in and taken out, even if the opening and closing operations for attachment and detachment with the watch case are repeated, the folded portion has the effect that the return closing pressure is not attenuated.

Further, since one or a plurality of pressing pieces for closing are provided on the upper piece or the lower piece of the leaf spring member, it is said that the clamped spring bar has a stable orientation and is prevented from accidentally coming off. Produce an effect. Also, since the folded back tip is slightly opened by the pressing piece, there is an effect that the tip can be easily hooked and opened without pressing the skin strongly.
