[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a watch band in which a number of pieces are flexibly connected by hinge pins.

[0002]

[Prior art]

 2. Description of the Related Art As a metal watch band, a band is known in which a band piece is attached to each of two connecting ends of a middle piece with hinge pins, and a plurality of band pieces are flexibly connected to an inner surface thereof by a middle piece.

[0003]

[Problems to be solved by the invention]

 This type of conventional watch band has a structure in which the outer surface of the band piece and the middle piece (the surface that faces outward when wearing the watch band on the arm, the front surface) and the inner surface (the surface that touches the arm when wearing the watch band) are exposed on the front and back. Because of this, the inner (back) shape of the watch band is inevitably complicated, and there is a problem that sweat and dirt accumulate in the gaps between the pieces, which easily corrode the pieces and hinge pins. . This is awkward because the more elaborate the design of a watch band, the larger it becomes.

In order to increase the degree of bending, the hinge pins must be provided on the inner surface as much as possible. In such a case, the amount of opening between the pieces generated when the watch band is worn on the arm is increased. There is dissatisfaction that the appearance is impaired.

[0005] An object of the present invention is to solve the above-described conventional problems, and an object of the present invention is to provide a watch band that can easily be simply rearranged in shape regardless of the surface shape. Another object of the present invention is to provide a watch band having a good wearing feeling, a thin side profile and a good appearance. Another object of the present invention is to provide a watch band that can reduce the amount of opening between pieces that occurs when the watch is worn. Still another object of the present invention is to provide a watch band which can easily develop a design freely.

[0006]

[Means for Solving the Problems]

 In order to achieve at least one of the above-mentioned objects, the invention according to claim 1 is characterized in that a band piece is attached to each of two connecting ends of a middle piece with a hinge pin so that a plurality of band pieces can be freely bent toward the inner surface thereof. In the watch band connected by a piece, the connecting end of each of the above-mentioned middle pieces is fitted into a recess formed on the outer surface between both ends of each of the substantially rectangular band pieces, respectively, and the bending of each of the above-mentioned band pieces. Is restricted by contact between the connecting edges of adjacent band pieces and / or contact of the bottom face of the concave portion of the band piece with the lower surface of the middle piece.

[0007] According to this means, the inner surface of the middle piece is covered with the recess of the band piece and is not exposed on the back surface (inner surface) of the watch band. When the watch band is bent in a bridge shape, unnecessary bending is restricted by the contact between the connecting edges of the adjacent band pieces and / or the contact of the bottom surface of the concave portion of the band piece with the lower surface of the middle piece.

[0008] In the watch band according to the first aspect, the outer surfaces of both end portions of the band piece are convexly curved in a connecting direction of the band piece and a direction orthogonal to the connecting direction, and the inner surface of the band piece is It is preferable to bend convexly in the orthogonal direction (claim 2). In this configuration, the thickness of the side end face of the band piece is inevitably thin, and the outer surfaces of both side ends of the band piece are curved convexly in the connecting direction of the band piece, and the outer surface is bent when the watch band is bent. The appearance of the watch band is beautiful because it has a gentle and natural curved surface. Also, the inner surface of the watch band is convexly curved in the orthogonal direction, so that the feeling of contact with the skin is softened.

In the watch band of the first or second aspect, it is preferable that the inner surface of each middle piece has a concave V shape that increases the degree of bending of the band piece (claims 3 and 4). In this configuration, the degree of curvature of the band piece is increased, and the thickness of the middle piece when the watch band is bent is reduced by the substantially thinner thickness of the inner piece having a concave V-shaped inner surface. In addition, since the hinge pin can be moved away from the inner surface and closer to the outer surface side, the amount of opening between the pieces which occurs when the hinge pin is attached to the arm is reduced.

[0010] In the watch band according to any one of claims 1 to 4, the middle piece may be constituted by a plurality of members of different colors arranged side by side in a direction perpendicular to the connecting direction. 5, claim 6, claim 7, and claim 8). In this configuration, the design can be improved by making some of the members constituting the middle piece gold, for example, and a more sophisticated watch band can be obtained.

The band piece 1 and the middle piece 3 are connected to each other by a hinge pin 5 and can be bent to the inner side. That is, between two adjacent band pieces 1 and 1, the middle piece 3 has one connecting end 3b in the recess 1b of one band piece 1 and the other connecting end 3b in the other. Each of the band pieces 1 and 1 is flexibly connected to each other by being inserted into the recesses 1b of the band piece 1 and inserted into the insertion holes 3d from the through holes 1d of the band piece 1 to bend. ing. The hinge pin 5 is processed in a known manner so that a circular end surface shape does not appear on the side end surface 1c of the band piece 1.

As described above, the band piece 1 and the middle piece 3 are bendable to the inner side, and the connecting edges 1e, 1e (FIGS. 2, 3) of the band pieces 1, 1 adjacent to each other are connected. , And the abutment of the concave bottom surface 1bt of the band piece 1 against the lower surface 3U of the middle piece 3 restricts their bridge-like bending.

Due to errors in processing or assembling the band piece 1 and the middle piece 3, etc., the connecting edges 1e, 1e abut on each other and the recess of the band piece 1 with respect to the lower surface 3U of the middle piece 3. In some cases, only one of the contact of the bottom surface 1bt may be realized, but there is no particular problem. Further, the connecting edges 3e, 3e on the inner surface side of the middle pieces 3, 3 come into contact with each other (FIG. 3), but this does not necessarily have to come into contact. The bending of the middle pieces 3, 3 toward the outer side is restricted by the contact between the connecting edges 3f, 3f on the outer side (FIG. 2).

In FIG. 1, reference numeral 7 denotes an assembling bracket for assembling a required buckle, and reference numeral 9 denotes an assembling bracket for assembling a required timepiece, which are attached to the band pieces 1 at both ends by hinge pins. Have been.

The main member 11 and the side members 12, 12 are arranged such that the main member 11 is disposed between the side members 12, 12, and the band members 1 are arranged side by side in the orthogonal direction Y orthogonal to the connecting direction X. The band pieces 1 and 1 are fitted into the recesses 1b, and the hinge pins 5 are inserted into the insertion holes 3d to connect the band pieces 1 and 1 freely. Since the other structure of the watch band B is the same as that of the watch band A, the same members and the like are denoted by the same reference numerals and description thereof is omitted.

In the watch band B, the following advantages are obtained in addition to the advantages (a) to (e) of the watch band A. (F) Since the middle piece 3 is composed of the main member 11 and the side members 12 and 12 and the side members 12 and 12 are of a golden color that resembles "gold", the design becomes elaborate and high-grade. The feeling is improved.

The band piece 1 and the middle piece 3 of the watch band A are both silver-white such as stainless steel, but one or both of them may be gold-finished. Further, the number of members constituting the middle piece 3 of the watch band B is not limited to the one shown in the figure, and may be two or four or more. In any case, the watch band B has a variety of band structures.

In the watch bands A and B, the planar shapes and the number of connected band pieces 1 and the middle pieces 3 are not limited to those shown in the figures, but are arbitrary. Further, as the mounting brackets 7 and 9 are used corresponding to the structure of the buckle or the watch, the structure is arbitrary. The outer surfaces of the band pieces 1 and the middle piece 3 of the watch bands A and B are decorated with irregularities and the like as necessary.
