Description

[Detailed explanation of the idea] This invention concerns a watch band.

Conventionally, a wide variety of watch bands have been devised and put into practical use, but there has been a particularly strong trend towards reducing costs by simplifying the structure of the components and reducing the number of parts.

However, if the structure is simplified, the design effect is low and the product value is lowered, and the flexibility when worn on the wrist is reduced.

The second idea was made in view of the above circumstances, and its purpose is to simplify the structure, reduce the number of parts and the number of assembly steps, and also to make it fit the wrist better and reduce force, and also to have a design effect. Our goal is to provide watch bands with a high level of quality.

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

In FIGS. 1A-D and 2, reference numeral 1 denotes an exterior body made by pressing a metal plate or the like, forming a substantially U-shaped cross section, and cutting out both side walls 1a and 1a to form opposing windows. 1b,l
b.

Reference numeral 2 designates a piece that is combined with the exterior body 1, and a connecting piece 4 is formed by bending one side 3a of a rectangular bottom plate 3 upward into an L-shape. Both ends protrude in both directions to connect the projecting pieces 4a, 4a, and the inner surfaces of both side walls 1a, 1a of the exterior body 1 are attached to both ends (usually both ends in the longitudinal direction) of the bottom plate 3. a clamping piece 5 that engages with the
5, and the clamping piece 5 is arranged parallel to the bottom plate 3 and bent upward by the thickness of the exterior body 1 in a crank shape,
On the other hand, the other side of the bottom plate 3 and a part of the clamping piece 5 are cut out corresponding to the connecting piece 4 to form the whole.

Reference numeral 6 denotes a middle piece used to suppress play between the exterior body 1 and the piece body 2, and its both ends 6a, 6a are formed in substantially the same planar shape as the clamping pieces 5, 5 of the piece body 2. A notch 6b is formed into which the connecting piece 4 of the bridge body 2 is inserted, and the inner surface of the notch 6b restricts the movement of the connecting piece 4 in the width direction of the watch band, and also prevents the connecting piece 4 from moving in the width direction of the watch band. The movement of the watch band 1 in the longitudinal direction is restricted by the side wall portion 1a of the body 1.

Further, in the illustrated example, the thickness of the middle piece 6 is the same as that of the royal palace [exterior body 1 and piece body 2].

In order to connect a watch band consisting of the outer body 1, the bridge body 2 and the middle bridge 6, the middle bridge 6 is placed on the clamping piece 5.5 of the bridge body 2 to form a set. After arranging the plurality of sets, the side window portion 1b of the exterior body 1 is inserted so as to cover one side of the bottom plate 3 of the piece body 2 and the protruding piece 4a of the connecting piece 4 of the other piece body 2.
lb facing, cover both side walls 1a and la of the exterior body 1, and bend the protruding parts of the side walls 1a and la at a substantially right angle from the position of the chain line in FIG. 2 as shown by the arrow A, By sequentially connecting the outer body 1, the piece body 2, and the middle piece 6 in this manner, the watch band is completed as shown in FIGS. 1A to 1D.

The watch band configured as described above has the connecting piece 4 of the piece body 2.
Rotation is performed around the protruding piece 4a, and this protruding piece 4
It can be made freely rotatable by making the vertical dimension of a slightly smaller than the vertical dimension of the hole formed in the side wall portion 1a of the exterior body 1.

Further, since the vicinity of the center of rotation of the connecting piece 4 is held between the side wall portion 1a of the exterior body 1 and the inner surface of the cutout portion 6b of the middle piece 6, as shown in the first diagram, the aforementioned exterior body 1
While allowing relative rotation between the body 2 and the piece body 2, play between the two can be suppressed as much as possible.

Furthermore, by providing a gap between the bottom plates 3, 3 of adjacent pieces 2, as shown in FIGS. 1B and 1D, the piece can be rotated more freely and fits comfortably on the wrist.

Moreover, even in such a case, there is no risk that the backlash will become large due to the action of the middle piece.

In addition, in the example of FIG. 1 and FIG. 2, the outer body 1, the bridge body 2, and the middle bridge 6 are made to have approximately the same thickness, and the thickness of the watch band is approximately four times the thickness of one plate. , the thickness of each may be changed; in particular, by increasing the thickness of the middle piece 6, the thickness of the watch band can be increased.

Further, the clamping piece 5 of the bridge body 2 can be formed narrowly, and by making the constituent parts thinner as appropriate, it is possible to form a more flexible watch band.

Furthermore, as shown in the illustrated example, it is possible to have a configuration in which both the front and back surfaces are substantially planar and do not have uneven portions or stepped portions.

As detailed above, the watch band of this invention consists of an exterior body, a bridge body, and a middle bridge, and has a small number of parts, and is assembled by inserting the exterior body into the bridge body and bending both side walls at approximately right angles. The assembly work is simple, and the number of assembly steps is low, reducing costs.The watch band is flexible due to the rotating movement around the protruding piece of the bridge body and the anti-backlash action of the middle bridge. It has excellent features such as being able to form a set of exterior body and piece body into a narrow shape that fits well on the wrist, less rattling, and the thickness can be freely adjusted, increasing the product value. have an effect.
