Description

  The present invention is applied to a watch band and the like, and relates to a band having a configuration in which a plurality of inner pieces and outer pieces are connected by a connecting shaft.

  In many watch bands, the upper side is an exterior surface, and the lower side is composed of an inner piece and an outer piece that are surfaces that contact the wearer's arm. As for the configuration of the band, the holes provided in the outer pieces arranged on the outer both sides of the inner piece are aligned with the through holes provided in the inner piece, and a connecting shaft is inserted into the through hole and the holes. The inner piece and a plurality of outer pieces are sequentially connected.

As the attachment of the connecting shaft, there are a configuration in which the connecting shaft is press-fitted from the outside into a hole penetrating the inner piece and the outer piece, or a connecting shaft itself having a screw structure. However, in this case, the end of the connecting shaft is exposed, and the end surface is visible from the outside.
For this reason, in order to improve the appearance, various band configurations devised so as not to expose the end and end face of the connecting shaft from the side face of the band have been proposed and implemented.

  For example, in Patent Documents 1 and 2, the connecting shaft is not exposed to the side of the piece, and the lower side (back surface) of the piece is screwed or the connecting shaft is screwed to remove the piece from the upper and side surfaces of the band. The connecting member is not visible.

  Further, in Patent Documents 3 and 4, the connecting shaft is not exposed on the side of the piece, but a stopper member having a concave elasticity is fitted to the lower side of the piece, and the connecting shaft is locked by a protrusion provided on the stopper member. This prevents the piece connecting member from being seen from the upper and side surfaces of the band.

  However, in the above-described prior art, in Patent Documents 1 and 2, although the end surface of the connecting shaft is not exposed on the side portion of the piece, a screw head larger than the end surface of the connecting shaft is exposed on the lower surface of the band. In addition, in this configuration, since a small screw for the band is attached, complicated operations such as screwdriver are involved.

  Further, in Patent Documents 3 and 4, although the end surface of the connecting shaft is not exposed on the side of the piece, the bottom surface of the stopper member that is larger than the end surface of the connecting shaft is exposed on the lower surface of the band. Further, the stopper member has a complicated structure as a part of the band and is large. Therefore, the cost of the entire band becomes high.

  Therefore, in view of the problems of the prior art, the present invention does not expose the connecting shaft for connecting the pieces with a simple configuration, improves the appearance, and is advantageous in terms of cost compared to the prior art. The purpose is to provide a band.

  In order to solve the above problems, the present invention provides an inner piece provided with a pair of through-holes therein, an outer piece provided with a pair of receiving holes inside and disposed on both sides of the inner piece, A connecting shaft inserted into the receiving hole of the outer piece through the through hole of the piece, and the connecting shaft in a state in which one of the receiving holes of the adjacent outer piece is aligned with each through hole of the inner piece. In the band formed by connecting the plurality of inner pieces and the plurality of outer pieces, the opening on the side of each outer piece facing the other outer piece is lower than the horizontal direction. A long hole is provided to reach the receiving hole, and a locking pin is inserted into the long hole to lock the connecting shaft.

  With the above configuration, a simple locking pin is used, and the opening position of the long hole in the outer piece into which the locking pin is inserted is considered so that the end surface of the connecting shaft cannot be easily and easily seen from the outer periphery of the piece. can do.

  In addition, by providing inclined surfaces that are inclined inwardly at the lower corners of each outer piece, and by providing the opening of the elongated hole on the inclined surface, there is no hindrance to the rotation of the outer piece, and band arms, etc. It does not reduce the feeling of fit.

Further, the outer pieces are configured such that the outer pieces can be rotated upwards around the connecting shaft, and the downward rotation is restricted in a range in which the opening cannot be seen from the upper exterior surface side. Thus, the opening of the long hole can be hidden from the upper exterior surface side in normal use.

  In addition, by forming a rotation restricting surface that abuts the side surface of the adjacent outer piece on the side surface of the outer piece so that the opening cannot be seen from the upper exterior surface side, it is possible to easily restrict the turning of the piece by external shape processing of the piece. become.

  Moreover, manufacture of a connection shaft becomes easy by making the said connection shaft into flat plate shape.

  In addition, after inserting the locking pin into the long hole, the locking pin is securely stopped by injecting an adhesive or resin into the long hole, and the end of the locking pin is exposed to the outside. Can be coated.

According to the present invention, since the end face of the connecting shaft that connects the outer piece and the inner piece can be hidden from the outer periphery of the piece only by inserting the locking pin into the outer piece. As a result, the appearance can be improved more easily and easily than in the prior art without increasing the cost.
Moreover, the practical effect is great because it can be applied to a piece made of a solid material such as a ceramic material.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1-4, 1 is a plurality (only two are shown in FIGS. 1 and 2), and 2 is a plurality (only three are shown on both sides of the inner piece 1 in FIGS. 1 and 2). The outer piece 3 has a circular through hole provided in a pair in each inner piece 1, 4 has a rectangular shaped receiving hole provided in a pair so as not to penetrate each outer piece 2, and 5 is a flat plate shape , 6 is a locking pin, and 7 is a long hole into which the locking pin 6 is inserted. The long hole 7 has an opening 7 a formed on the outer peripheral surface of the outer piece 2, and is provided in the outer piece 2 so as to pass through the through hole 3.

  The inner piece 1 is integrally formed from a ceramic material or the like, and has an approximately semicircular outer shape. The outer piece 2 is also integrally formed from a ceramic material or the like, and the outer shape is substantially semicircular, but the outer peripheral shape is different from that of the inner piece 1.

  The outer peripheral surface of the outer piece 2 is formed with inclined surfaces 2a inclined inward at the lower corners of the side surface facing the adjacent outer piece 2, and the flat surface 2b is formed above the inclined surface 2a. The upper part of the arcuate surface 2c extends to the exterior surface.

  As shown in FIG. 4, the adjacent outer pieces 2 can move along the arcuate surfaces 2 c and can rotate upward. However, the downward rotation of the adjacent outer pieces 2 is prevented by the contact between the inclined surfaces 2a, and the rotation is restricted.

  An opening 7a of the long hole 7 is formed at the boundary between the inclined surface 2a and the flat surface 2b of the outer piece 2, and the long hole 7 is provided so as to extend toward the upper through hole 3 with the opening 7a down. ing.

Next, the assembly of the band of this embodiment will be described.
As shown in FIG. 3, the inner pieces 1 are arranged, the connecting shafts 5 are inserted into the through holes 3 adjacent to each other, and the outer pieces 2 are arranged so as to straddle the two inner pieces 1. Both ends of the connecting shaft 5 are inserted into the receiving holes 4 of the inner pieces 1 respectively. In this state, the locking pin 6 is inserted into the outer piece 2 from the opening 7 a of each long hole 7.

  The state shown in FIG. 2 is a state in which the locking pin 6 is inserted, the center portion of the locking pin 6 is engaged with the engaging hole 5a of the connecting shaft 5, and both end portions of the locking pin 6 are engaged. It fits in the inner periphery of the long hole 7. In this state, the outer piece 2 and the inner piece 1 are connected via the connecting shaft 5, and the inner piece 1 and the outer piece 2 can be rotated with respect to each other via the connecting shaft 5. Therefore, each piece rotates along the attached portion of the band and fits to the attached portion.

  The opening 7a of the long hole 7 can be covered to the outside by injecting an adhesive or resin having the same color as the outer color of the outer piece 2 into the long hole 7 as necessary.

  In this way, the inner piece 1 and the outer piece 2 are sequentially connected. At that time, as shown in FIG. 4, one adjacent outer piece 2 is rotated upward to open the opening 7a of the long hole 7 to the outside. In this state, the locking pin 6 is fitted into the opening 7a of the long hole 7, whereby the connecting shaft 5 already inserted in the inner piece 1 and the outer piece 2 is locked as described above. By doing in this way, the attachment work of the locking pin 6 becomes easy.

  As described above, in the outer piece 2, the inclined surfaces 2 a of the adjacent outer pieces 2 are in contact with each other, and the rotation of the outer piece 2 is restricted by preventing the downward rotation of the outer piece 2. In the usage method of mounting on the normal arm of the band, the outer piece 2 does not rotate too much downward and the opening 7a does not appear on the upper side of the band. Therefore, the opening 7a and the end surface of the connecting shaft 3 are on the exterior surface side. There is nothing you can see.
