Description

Technical Field

[0001] The present invention relates to a band provided with connecting pieces used for ornaments such as watches and bracelets.

Background Art

[0002] Bands are sometimes used for ornaments such as watches and bracelets. In such bands, bands provided with connecting pieces that can ensure sufficient strength against overall torsion, have a good texture, and can fit well on the wrist are often used. The connecting pieces are arranged with a plurality of outer pieces and inner pieces alternating with each other, and adjacent outer pieces and inner pieces are connected by connecting shafts respectively (see, for example, Patent Document 1). Bands provided with connecting pieces that can ensure sufficient strength against overall torsion of the band, have a good texture, and can fit well on the arm are disclosed (see, for example, Patent Document 2).

[0003] To adjust the length of the band, the outer pieces or inner pieces constituting the band are often removed. As adjustment mechanisms for removing the outer pieces or inner pieces, various structures have been proposed. Structures such as screwing a connecting pin for connecting the outer pieces or inner pieces from the side of the outer pieces or inner pieces, and structures using an elastic long shaft have been used.

[0004] FIG. 6 is a perspective view showing a connecting piece 200 constituting the band, and FIG. 7 is a perspective view showing a main part of the connecting piece 200. The connecting piece 200 includes an outer piece 210 and an inner piece 240. The outer piece 210 has an outer right piece 220 and an outer left piece 230, and the outer right piece 220 and the outer left piece 230 are connected. Through holes 221, 222 (222 is not shown) are provided in the outer right piece 220. Through holes 231, 232 are provided in the outer left piece 230.

[0005] The inner piece 240 comprises a first inner piece 250 located on the outer right piece 220 side, a second inner piece 260 located on the outer left piece 230 side, and a third inner piece 270 sandwiched between the first inner piece 250 and the second inner piece 260. The first inner piece 250, the second inner piece 260, and the third inner piece 270 are provided with through holes 251, 261, 271 (251, 271 not shown) and through holes 252, 262, 272 (252 to 272 not shown).

[0006] Through holes 221, 252, 262, 272, and 231 are inserted with connecting pins 280 to pivotably connect adjacent connecting pieces 200. Through holes 222, 251, 261, 271, and 232 are inserted with press-fit pins 290 to integrate and fix the outer piece 210 and the inner piece 240 together.

[0007] These connecting pieces 200 are processed, such as by grinding, to conceal the ends of the press-fit pins 290 visible through the through-holes 232. Therefore, processing work is required.

[0008] Figure 8 is a perspective view showing the connecting piece 300, and Figure 9 is a perspective view showing the main part of the connecting piece 300. The connecting piece 300 comprises an outer piece 310 and an inner piece 340. The outer piece 310 has an outer right piece 320 and an outer left piece 330, and the outer right piece 320 and the outer left piece 330 are connected by a connecting rod 325. The outer right piece 320 is provided with through holes 321 and 322. The outer left piece 330 is provided with through holes 331 and 332.

[0009] The inner piece 340 comprises a first inner piece 350 located on the outer right piece 320 side, a second inner piece 360 ​​located on the outer left piece 330 side, and a third inner piece 370 sandwiched between the first inner piece 350 and the second inner piece 360. The first inner piece 350, the second inner piece 360, and the third inner piece 370 are provided with through holes 351, 361, 371 and 352, 362, 372, and recesses 353, 363, 373. The recesses 353, 363, 373 fit into the connecting rod 325.

[0010] Through holes 321, 352, 362, 372, and 331 are inserted with connecting pins 390 to pivotably connect adjacent connecting pieces 300. Through holes 322, 351, 361, 371, and 332 are inserted with press-fit pins 380 to integrate and fix the outer piece 310 and the inner piece 340 together.

[0011] In such a connecting piece 300, the ends of the press-fit pins 380 are visible through the through holes 331 and 332, which detracts from the aesthetic appearance. [Prior art documents] [Patent Documents]

[0012] [Patent Document 1] Japanese Patent Publication No. 2012-165878 [Patent Document 2] Japanese Patent Publication No. 2005-034293 [Overview of the Initiative] [Problems that the invention aims to solve]

[0013] As mentioned above, in bands equipped with connecting links, the ends of the press-fit pins are exposed on the side of the band. In this case, there was a problem in that the band did not look good when viewed from the side. Furthermore, if the ends of the press-fit pins were to be hidden in order to improve the aesthetics, a new problem arose in that polishing would have to be performed. Moreover, since the outer and inner links are integrated and fixed together by the press-fit pins, for example, if one of the outer or inner links is damaged and needs to be replaced, it is not possible to separate them without breaking the outer and inner links, so the undamaged link also has to be replaced and the connecting link has to be discarded.

[0014] Therefore, the present invention aims to provide a band having connecting pieces that allow the outer piece and the inner piece to be integrated and fixed without using press-fit pins, enabling easy assembly, allowing the outer piece and the inner piece to be separated without damaging them, and further enabling a beautiful appearance, especially when the band is viewed from the side. [Means for solving the problem]

[0015] In the present invention, a band having a plurality of connecting pieces connected in the longitudinal direction, the connecting piece comprises a first outer piece and a second outer piece spaced apart in the width direction of the band, an outer piece connecting rod connecting the first outer piece and the second outer piece, a first outer piece through hole and a second outer piece through hole that penetrate the first outer piece and the second outer piece in the width direction and have a common axis, an inner piece positioned between the first outer piece and the second outer piece, straddling the outer piece connecting rod, spaced apart in the width direction, and in contact with the first outer piece and a second inner piece in contact with the second outer piece, and an inner piece connecting rod that connects the first inner piece and the second inner piece and in contact with the longitudinal side end face of the outer piece connecting rod, The device comprises a fixing pin that penetrates the outer piece connecting rod and the inner piece connecting rod from the outer piece connecting rod side toward the inner piece connecting rod, a central piece positioned between the first inner piece and the second inner piece and straddling the outer piece connecting rod and the inner piece connecting rod, and a first inner piece through hole, a second inner piece through hole, and a central piece through hole that penetrate the first inner piece, the second inner piece, and the central piece in the width direction, respectively, and have a common axis line, and a connecting pin that rotatably penetrates the first inner piece through hole, the second inner piece through hole, and the central piece through hole of a specific connecting piece among the plurality of connecting pieces, and the first outer piece through hole and the second outer piece through hole of a connecting piece adjacent to this specific connecting piece in the length direction. [Effects of the Invention]

[0016] According to the band of the present invention, the outer member and the inner member can be integrated and fixed without using a press-fit pin, enabling easy assembly. Moreover, the outer member and the inner member can be separated without being damaged, and further, the appearance, particularly the appearance of the band when viewed from the side, can be made beautiful.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a connecting member of a watch band 10 which is an embodiment of the present invention, FIG. 2 is an explanatory view of the main part of the watch band 10 of this embodiment cut along the line A-A in FIG. 3 and viewed in the direction of the arrow, FIG. 3 is a perspective view showing a connecting member incorporated in the watch band 10 of this embodiment, FIG. 4 is an exploded perspective view showing the connecting member of this embodiment, and FIG. 5 is an explanatory view showing the assembling process of the connecting member of this embodiment. In the figures, L indicates the length direction of the watch band 10, and W indicates the width direction of the watch band 10.

[0019] The watch band 10 comprises a plurality of connecting links connected in the longitudinal direction L, and these connecting links are composed of an outer link portion 20 and an inner link portion 60. The outer link portion 20 comprises a first outer link 30 and a second outer link 40 spaced apart in the width direction of the watch band 10, and an outer link connecting rod 50 that connects the first outer link 30 and the second outer link 40. The first outer link 30 and the second outer link 40 are provided with a first outer link through hole 31 and a second outer link through hole 41 that penetrate in the width direction W and have a common axis line. The outer link connecting rod 50 has an outer link fixing hole 51 into which a fixing pin 110, which will be described later, is inserted.

[0020] The inner piece section 60 is positioned between the first outer piece 30 and the second outer piece 40, straddling the outer piece connecting rod 50, spaced apart in the width direction W, and includes a first inner piece 70 that abuts the first outer piece 30 and a second inner piece 80 that abuts the second outer piece 40, an inner piece connecting rod 90 that connects the first inner piece 70 and the second inner piece 80 and abuts the side end face of the outer piece connecting rod 50 in the length direction L, and a central piece 100 that is sandwiched between the first inner piece 70 and the second inner piece 80, straddling the outer piece connecting rod 50 and the inner piece connecting rod 90.

[0021] The first inner piece 70 comprises a front end 71, a central part 72, and a rear end 73, with a first inner piece recess 74 formed on the lower side of the central part 72 that engages with the outer piece connecting rod 50. The second inner piece 80 comprises a front end 81, a central part 82, and a rear end 83, with a second inner piece recess 84 formed on the lower side of the central part 82 that engages with the outer piece connecting rod 50.

[0022] The first inner piece 70, the second inner piece 80, and the central piece 100 each have through-holes 71a, 81a, and 101a, respectively, that penetrate in the width direction W and share a common axis. The inner piece connecting rod 90 has an inner piece fixing hole 91 into which a fixing pin 110, described later, is inserted. The axis of the inner piece fixing hole 91 coincides with the axis of the outer piece fixing hole 51.

[0023] The central piece 100 comprises a tip portion 101, a central portion 102, and a rear end portion (contact portion) 103. A central piece recess 104 is formed on the lower side of the central portion 102, which engages with the outer piece connecting rod 50 and the inner piece connecting rod 90.

[0024] Fixing pins 110 are inserted into the outer piece fixing holes 51 and the inner piece fixing holes 91, and the central piece 100 covers them from above.

[0025] The watch band 10, configured in this way, is assembled as follows. As shown in Figure 4, the inner links 60 are placed on top of the outer links 20, and the first inner link recess 74 and the second inner link recess 84 are engaged with the outer link connecting rod 50 to position them. This causes the axis of the outer link fixing hole 51 and the axis of the inner link fixing hole 91 to coincide, and the outer links 20 and the inner links 60 are integrated by inserting the fixing pin 110. Note that the fixing pin 110 is not fixed in this state.

[0026] Next, the central recess 104 of the central piece 100 is fitted into the outer piece connecting rod 50 and the inner piece connecting rod 90. As shown in Figure 2, the rear end 103 of the central piece 100 prevents the fixing pin 110 from coming out, and the fixing pin 110 is fixed in the outer piece fixing hole 51 and the inner piece fixing hole 91, so that the outer piece part 20 and the inner piece part 60 are integrated and fixed together as a connecting piece.

[0027] In this configuration, after the outer piece portion 20 and the inner piece portion 30 are integrated and fixed, adjacent connecting pieces are pivotably connected to each other by connecting pins 120. Specifically, the connecting pins 120 are pivotably passed through the first inner piece through hole 71a, the second inner piece through hole 81a, and the central piece through hole 101a of a particular connecting piece, and through the first outer piece through hole 31 and the second outer piece through hole 41 of a connecting piece adjacent to this particular connecting piece in the longitudinal direction L.

[0028] In this way, the connecting links are formed, and the links are connected until the desired length is obtained, completing the watch band 10.

[0029] With the watch band 10 constructed in this way, the outer links 20 and the inner links 60 can be integrated and fixed without using press-fit pins, allowing for easy assembly and separation of the outer links 20 and the inner links 60 without damaging them. Furthermore, the fixing pins 110 are not exposed on the outside of the watch band 10, eliminating the need for polishing or other processing. Therefore, it is possible to achieve a beautiful appearance.

[0030] Although embodiments of the present invention have been described above, it goes without saying that the present invention is not limited thereto and various improvements and modifications are possible without departing from its spirit.

[0031] For example, although the above example described it as a watch band, it can also be used for jewelry bands, etc. [Industrial applicability]

[0032] This invention is effective as a band that allows for adjustment of the length of watch bands, jewelry bands, and other similar bands. [Explanation of Symbols]
