Description

The present invention relates to connecting bands.

As a band for mounting the wristwatch on the wrist, there is a connecting band in which a plurality of pieces are connected in the longitudinal direction. Such a connecting band is connected by passing a common connecting pin through a connecting hole formed in each of two pieces adjacent to each other in the longitudinal direction and extending in the width direction of the piece.

Here, since the connecting holes are exposed at the end surfaces (side surfaces of the connecting band) of the outer pieces arranged at both ends in the width direction of the piece body, it is required to improve the appearance quality (look).

Therefore, it is possible to make the boundary between the connecting hole and the connecting pin inconspicuous by press-fitting the connecting pin into the connecting hole, polishing the end face of the outer piece together with the connecting pin, and then further performing hairline processing or plating. Has been done.

Further, there is also known a connecting band in which a cover for covering the end surface of the outer piece is attached to both outer sides in the width direction of the piece body (for example, refer to Patent Document 1). The cover of the connecting band is arranged at a position to close both ends of the connecting hole into which the connecting pin is loosely inserted, in order to prevent the connecting pin loosely inserted into the connecting hole of the piece from falling off. It is fastened to the end surface of the outer piece.

JP, 2004-141608, A

However, when mechanical processing such as polishing is performed after connecting the pieces as the connecting band, the abrasive powder generated by the mechanical processing enters the minute gap between the connecting hole and the connecting pin, and then Even after cleaning, it is difficult to completely remove the polishing powder and the like within the limited manufacturing cycle time.

In addition, the one that covers the outside of the outer piece with a cover does not require machining after assembly as a connecting band, so there is no problem of the above-mentioned polishing powder remaining, but there is a screw hole for fixing the cover to the outer piece. However, there is a problem in that it is necessary to newly form the bridge, and it takes a lot of man-hours for fastening work to fasten the screw to fix the cover. Further, a fixing screw appears on the outer surface of the cover, which causes a problem in appearance quality.

The connecting hole is not limited to the hole through which the connecting pin that connects the pieces is inserted, but is also arranged at both ends in the width direction when the piece is formed by connecting a plurality of pieces with the connecting pin. When two outer pieces and one or more middle pieces arranged between the two outer pieces are connected by connecting pins, a connecting pin that connects the outer piece and the middle piece is inserted. Hole is also included.

The present invention has been made in view of the above circumstances, and it is possible to improve the appearance quality without performing mechanical processing such as polishing after assembling a connecting band and newly providing a screw hole in a piece. Intended to provide a band.

The present invention provides a plurality of bridge bodies having connection holes extending in the width direction of a connection band, a connection pin commonly passed through the connection holes of the plurality of bridge bodies, and a plurality of the bridge bodies. Outer pieces arranged at both ends in the width direction, which are provided on the outer side in the width direction and which cover at least a part of the outer end surfaces in the width direction of the outer piece, and the connecting holes of the outer pieces. And an end cap having a protrusion formed thereon.

According to the connecting band of the present invention, appearance quality can be improved without performing machining such as polishing after assembling the connecting band, and without newly providing a screw hole in the bridge.

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

<Structure>
FIG. 1 is a plan view of a connecting band 100 for a wristwatch, which is an example of a connecting band according to the present invention, viewed from the front side, and FIG. 2 is a piece 10 which is a structural unit of the connecting band 100 shown in FIG. FIG. 5 is an exploded perspective view showing the end caps 51 and 52 in an exploded manner.

In FIG. 1, one piece body 10 and a set of end face caps 51 and 52, which are 100 constituent units of the connecting band, are indicated by solid lines, and the other piece body 10 and end face caps 51 and 52 are indicated by alternate long and two short dashes lines. This is for easier understanding. 3 is a sectional view showing a section taken along a plane including the two connecting holes 22b and 22c in FIG.

In the illustrated connecting band 100, a plurality of pieces 10 are arranged along the length direction L of the connecting band. As shown in FIG. 2, the piece 10 which is a structural unit of the connecting band 100 has two outer pieces 21, 22 arranged at both ends in the width direction W (direction orthogonal to the length direction L) of the connecting band 100. And one middle piece 30 arranged between the outer pieces 21 and 22 are connected by a connecting pin 40 to be integrally formed.

A bridge portion 23 is arranged between the two outer pieces 21 and 22, and the two outer pieces 21 and 22 are integrally connected in an H-shape via the bridge portion 23. The width of the bridge portion 23 is formed slightly wider than the width of the middle piece 30. The one in which the two outer pieces 21, 22 at both ends are integrally formed by the bridge portion 23 as described above may be hereinafter simply referred to as the outer piece 20.

The outer piece 21 is formed with connecting holes 21b and 21c near both ends in the length direction L and extending in the width direction W and penetrating therethrough. The bridge portion 23 is connected to the outer piece 21 between the connecting holes 21b and 21c.

The outer piece 22 is also formed with connecting holes 22b and 22c near both ends in the length direction L and extending in the width direction W and penetrating therethrough. The bridge portion 23 is connected to the outer piece 22 between the connecting holes 22b and 22c.

In the outer piece 20 integrated with the bridge portion 23, the connecting hole 21b and the connecting hole 22b are arranged in a straight line, and the connecting hole 21c and the connecting hole 22c are arranged in a straight line.

In the middle piece 30, a groove 30a extending in the width direction W is formed near one end in the length direction L. Further, the middle piece 30 has a connection extending in the width direction W near the other end in the length direction L and near the middle of the length direction L (on the other end side of the groove 30a). Holes 30b and 30c are formed.

Then, as shown in FIG. 3, the bridge portion 23 of the outer piece 20 is fitted into the groove 30a, and in this fitted state, the connecting holes 21c and 22c and the connecting hole 30c are arranged in a straight line. One common connecting pin 40 is loosely passed through the connecting holes 21c, 30c, 22c arranged in a straight line to form the piece body 10 in which the outer piece 20 and the middle piece 30 are integrated. It

The connecting pin 40 is formed to be longer than the width of the middle piece 30 and shorter than the width of the outer piece 20. Therefore, as shown in FIG. 3, in a state where the connecting pin 40 connects the outer piece 20 and the middle piece 30, both ends of the connecting pin 40 have outer surfaces in the width direction W of the outer pieces 21 and 22 (outer piece). It does not reach both end surfaces of 20) 21a and 22a.

Further, since the outer piece 20 and the middle piece 30 that form the piece body 10 are engaged with each other at two points of the connecting pin 40 and the bridge portion 23, they do not rotate relative to each other.

In the state shown in FIG. 3, the connecting hole 30b of the middle piece 30 is aligned with the connecting hole 21b of the outer piece 21 and the connecting hole 22b of the outer piece 22 of the other piece body 10 connected in the length direction L. Another common connecting pin 40 is loosely passed through the connecting holes 21b, 30b, 22b arranged on these straight lines, whereby the pieces 10 are connected to each other.

At this time, since the pieces 10 are engaged with each other by only one connecting pin 40, the pieces 10 can relatively rotate around the connecting pin 40, and the connecting band 100 can be adjusted according to the thickness of the user's wrist. Is bent.

Further, the connecting band 100 of the present embodiment includes end face caps 51 and 52 on the outer side of the outer piece 20 in the width direction W, respectively. The end face cap 51 has a cover plate 51a and protrusions 51d and 51e.

The cover plate 51a is formed in the same cross-sectional contour shape as the outer surface 21a of the outer piece 21 in the width direction W (outer peripheral edge contour shape of the cross section orthogonal to the width direction), and is an example of a cover portion. The outer surface 51c of the cover plate 51a in the width direction W is formed as a flat surface without any unevenness. On the other hand, the inner surface 51b of the cover plate 51a facing the outer surface 21a of the outer piece 21 is also a flat surface, but has projections 51d and 51e extending in the width direction W.

The cover plate 51a does not have to cover the entire outer surface 21a of the outer piece 21, and may have a shape that covers at least a part of the surface 21a (a range including the connecting holes 21b and 21c).

The protrusions 51d and 51e are formed at positions corresponding to the connecting holes 21b and 21c of the outer piece 21 when the cover plate 51a is arranged so as to cover the entire outer surface 21a of the outer piece 21 without excess or deficiency. ..

Since the protrusions 51d and 51e are formed to have an outer diameter that provides an interference fit with the connecting holes 21b and 21c, they are press-fitted into the connecting holes 21b and 21c, respectively.

The end cap 52 has the same structure as the end cap 51, and has a cover plate 52a and projections 52d and 52e.

The cover plate 52a is formed in the same contour shape as the outer surface 22a of the outer piece 22 in the width direction W. The outer surface 52c of the cover plate 52a in the width direction W and the inner surface 52b opposed to the outer surface 22a of the outer piece 22 are flat surfaces without unevenness, but from the inner surface 52b in the width direction W. Extended protrusions 52d and 52e are formed.

The cover plate 52a does not have to cover the entire outer surface 22a of the outer piece 22 and may have a shape that covers at least a part of the surface 22a (a range including the connecting holes 22b and 22c).

The protrusions 52d and 52e are formed at positions corresponding to the connecting holes 22b and 22c of the outer piece 22 when the cover plate 52a is arranged so as to cover the entire outer surface 22a of the outer piece 22 without excess or deficiency. ..

Since the protrusions 52d and 52e are formed to have an outer diameter that provides a tight fit with the connecting holes 22b and 22c, they are press-fitted into the connecting holes 22b and 22c, respectively.

As shown in FIG. 3, the protrusions 51d and 51e are press-fitted into the connection holes 21b and 21c, respectively, so that the inner surface 51b of the cover plate 51a substantially comes into close contact with the outer surface 21a of the outer piece 21 and the protrusions 52d and 51e. 52e is press-fitted into the connecting holes 22b and 22c, respectively, so that the inner surface 52b of the cover plate 52a is held in a state in which the inner surface 52b is substantially in close contact with the outer surface 22a of the outer piece 22.

In this assembled state, the connecting pin 40 passed through the connecting holes 21b, 30b, 22b and the connecting pin 40 passed through the connecting holes 21c, 30c, 22c are biased to either side in the width direction W. Also, the length of the connecting pin 40 and the lengths of the protrusions 51d, 52d, 51e, 52e are set so that they do not come off from the two outer pieces 21, 22.

<Action>
In the connecting band 100 of the present embodiment configured as described above, the connecting holes 21b, 21c, 22b, 22c penetrating to the outer surfaces 21a, 22a of the outer pieces 21, 22 form the outer pieces 21, 22 from the outside. It is covered by the covering end face caps 51 and 52. Accordingly, in the connecting band 100, the connecting holes 21b, 21c, 22b, 22c are not exposed to the outside. Therefore, the connecting band 100 can improve the appearance quality.

Moreover, the connecting band 100 is exposed to the outside on the outer surfaces 51c, 52c of the end surface caps 51, 52, and the surfaces 51c, 52c have structures (projections 51d, 51e, 52d, 52e) does not appear. Therefore, it is possible to improve the appearance quality as compared with the cover of the prior art in which the screw that is the structure for connecting to the piece appears on the outer surface.

Further, since the surfaces 51c and 52c are flat surfaces having no unevenness, the connecting band 100 can give a clean impression and a high-class feeling. The surfaces 51c and 52c are not limited to flat surfaces and may have irregularities, and a structure for connecting to the piece 10 may appear, but it is preferable that such a structure does not appear.

Further, since the connecting band 100 does not need to be subjected to mechanical processing such as polishing after being assembled as the connecting band 100, polishing powder and the like will not remain even after the assembly as the connecting band 100 without washing.

Further, the connection band 100 is formed by pressing the protrusions 51d, 51e, 52d, 52e formed on the end caps 51, 52 into the existing connection holes 21b, 21c, 22b, 22c to form the end caps 51, 52. Since it can be held on the body 10, it is not necessary to form a screw hole for screwing the end surface caps 51 and 52 on the piece body 10 or to perform a fastening operation for screwing, thereby reducing the manufacturing cost. be able to.

When the protrusions 51d, 51e, 52d, 52e of the end caps 51, 52 and the outer pieces 21, 22 are made of metal, the protrusions 51d, 51e, 52d, 52e are press-fitted into the connecting holes 21b, 21c, 22b, 22c. Then, instead of holding the end surface caps 51, 52 on the piece body 10, the projections 51d, 51e, 52d, 52e are passed through the connection holes 21b, 21c, 22b, 22c, and the projections 51d, 51e, 52d. , 52e and the outer pieces 21, 22 may be fixed to each other by solid-phase joining to hold the end caps 51, 52 on the piece body 10.

Further, the projections 51d, 51e, 52d, and 52e may be press-fitted into the connection holes 21b, 21c, 22b, and 22c and solid-phase bonded to hold the end face caps 51 and 52 more firmly to the piece 10. ..

Further, in the connecting band 100, both ends of the connecting holes 21b and 22b and both ends of the connecting holes 21c and 22c are closed by the end surface caps 51 and 52, so that the connecting pin 40 has the connecting holes 21b, 22b, 21c and 22c. The connecting pin 40 does not drop out of the connecting holes 21b, 22b, 21c, 22c even if it is formed loosely.

Therefore, even if the connecting pin 40 is not fixed to the connecting holes 21b, 22b, 21c, 22c by press-fitting using a conventional C-ring or the like, the connecting pin 40 is removed from the connecting holes 21b, 22b, 21c, 22c. It will never fall out. This facilitates automation of the work of disposing the connecting pin 40 in the connecting holes 21b, 22b, 21c, 22c.

When the connecting pin 40 is press-fitted, a lubricant is used to reduce frictional resistance at the time of press-fitting. However, since the connecting band 100 of the present embodiment does not press-fit the connecting pin 40, it is also necessary to use a lubricant. Absent. However, the connecting band according to the present invention may be one in which a connecting pin is press-fitted into the connecting hole.

Further, in the connecting band 100, the end caps 51 and 52 may be formed of the same color and the same material as the bridge body 10, or the end caps 51 and 52 may be formed in a different color of the bridge body 10 or a different color. It may be formed of a material.

If the end caps 51, 52 and the piece 10 are formed in the same color, the entire connecting band 100 gives a clean impression with a single color, and the end caps 51, 52 and the piece 10 are formed in different colors. The formed one can give a decorative impression.

If the end caps 51, 52 are made of the same material as the piece 10 (for example, titanium), it gives a clean impression to the entire connecting band 100 and separates the end caps 51, 52 from the piece 10. The material formed with the material can give a decorative impression due to the difference in texture.

In general, the connecting band is close to a lug (a claw-shaped portion for attaching the connecting band to the case) formed on the case of the timepiece, and the size in the width direction W is increased or decreased. Has been. In this case, it is general that the widths of both outer pieces of the piece body are gradually increased or decreased to correspond.

On the other hand, in the connecting band 100, the plurality of pieces 10 themselves are formed with a constant width (the same width) including the portion close to the lug, and the widths of the end face caps 51 and 52 are gradually increased. It can be dealt with by gradually decreasing or gradually decreasing. That is, the end surface caps 51, 52 attached to some of the pieces 10 are formed so that the dimension in the width direction W is different from that of the other end surface caps 51, 52. Therefore, it is not necessary to manufacture a plurality of pieces 10 having different widths to form one connecting band 100.

In this case, although it is necessary to manufacture the plurality of end face caps 51 and 52 having different widths, the end caps 51 and 52 can be manufactured at low cost as compared with the case where the plurality of pieces 10 having different widths are manufactured.

Moreover, when manufacturing the pieces 10 having different widths, it is necessary to symmetrically form both sides in the width direction of the pieces 10, but it is very difficult to accurately and symmetrically form the pieces. ..

On the other hand, since the end cap 51 and the end cap 52 are separate parts, they are easier to mold than a single part that is symmetrically formed.

FIG. 4 is a cross-sectional view showing a modification of the protrusions 52d (51d) and 52e (51e) formed on the end face cap 52 (51), showing a cross-section taken along the outer surface 22a (21a) of the outer piece 22 (21). It is a figure.

The connecting band 100 of this embodiment is formed in a shape in which the two protrusions 52d, 52e (51d, 51e) of the end surface cap 52 (51) are press-fitted into the connecting holes 22b, 22c (21b, 21c). However, the connecting band according to the present invention is not limited to this form.

That is, for example, as shown in FIG. 4, of the two protrusions 52d, 52e (51d, 51e) of the end face cap 52 (51), only one protrusion 52d (51d) is press-fitted into the connecting hole 22b (21b). The other protrusion 52e (51e) formed in a shape may be a shape that provides an intermediate fit with no interference with the connecting hole 22c (21c).

In short, the other protrusion 52e (51e) may have a fitting shape such that the posture of the end surface cap 52 (51) with respect to the piece 10 is maintained (a rotation stopper), and the cross section shown in FIG. The shape does not have to be substantially rectangular.

In this way, the two protrusions 52d, 52e (51d, 51e) are not press-fitted together, but only one protrusion 52d (51d) is press-fitted, and the other protrusion 52e (51e) is not press-fitted. With the shape, the work of fixing the end cap 52 (51) to the piece 10 can be facilitated.

On the other hand, in the case where the two projections 52d and 52e (51d, 51e) are press-fitted together, the end surface cap 52 is smaller than in the case where only one projection 52d (51d) or the projection 52e (51e) is press-fitted. The holding force of (51) on the piece body 10 can be increased.

The connection band 100 described above is configured such that the protrusions 51d, 51e, 52d, 52e of the end caps 51, 52 are press-fitted into the connection holes 21b, 21c, 22b, 22c of the outer pieces 21, 22 to remove the end caps 51, 52 from each other. Although held by the pieces 21 and 22, it is preferable that the end surface caps 51 and 52 cannot be manually removed by the user from the outer pieces 21 and 22.

However, in the connecting band according to the present invention, some end caps may be manually detachably fixed to the piece. That is, the connecting band is required to be adjusted in length according to the length of the user's wrist, and as a structure that realizes such a request, it is common to adjust the number of pieces to be connected. Target.

Therefore, with respect to some of the pieces, the user who uses the timepiece may be allowed to connect and disconnect the connection without relying on a specialist. Specifically, of some of the plurality of pieces 10 that form the connecting band 100, the end surface caps 51 and 52 are detachably attached to the pieces 10.

As a result, the user himself removes the end caps 51, 52 from the piece 10, removes the piece 10 from the connecting band 100, or newly adds the piece 10 to connect the end caps 51, 52. By attaching and holding it on the piece body 10, it is possible to adjust the length by increasing or decreasing the number of the piece bodies 10 forming the connecting band 100.

FIG. 5 shows an example of a configuration in which the end caps 51 and 52 are detachably attached to the piece body 10 (outer pieces 21 and 22) while the end surface caps 51 and 52 are held by the piece body 10 as an outer piece. A groove having a diameter larger than the inner diameters of the connecting holes 21b, 21c, 22b, 22c is formed in the connecting holes 21b, 21c, 22b, 22c of 21, 22 and an O-ring 26 is arranged in each groove. 3 is a sectional view corresponding to FIG.

The inner diameter of the O-ring 26 in the connecting band shown in FIG. 5 is formed smaller than the inner diameters of the connecting holes 21b, 21c, 22b, 22c, and the outsides of the protrusions 51d, 51e, 52d, 52e of the end face caps 51, 52. The diameter is smaller than the inner diameters of the connecting holes 21b, 21c, 22b, 22c and larger than the inner diameter of the O-ring 26.

As a result, the protrusions 51d, 51e, 52d, and 52e are loosely inserted into the connection holes 21b, 21c, 22b, and 22c, but when the O-ring 26 is passed through, the O-ring 26 is elastically deformed to reduce frictional resistance. As a result, the end caps 51 and 52 can be held in the state of being attached to the piece 10.

On the other hand, when the end caps 51 and 52 held in the state of being attached to the outer pieces 21 and 22 are grasped with fingers or the like and a force for pulling them out from the outer pieces 21 and 22 is applied, the protrusions 51d, 51e, 52d and 52e are Although it receives frictional resistance due to elastic deformation of the O-ring 26, it can be removed from the outer pieces 21 and 22 by applying a force larger than the frictional resistance.

FIG. 6 is an exploded perspective view showing a modified example in which the outer pieces 22 and 21 have holding members 25 and 24 formed of an elastic material instead of the O-ring 26 shown in FIG. The outer pieces 22 and 21 shown in the drawing have recesses 22d and 21d formed on the surfaces facing the end caps 52 and 51, and holding members 25 and 24 are arranged in the recesses 22d and 21d.

The holding members 25 and 24 are made of an elastic material such as silicone and are formed in a size slightly larger than the recesses 22d and 21d. The holding members 25 and 24 are fitted into the recesses 22d and 21d and are held by the outer pieces 22 and 21.

The holding members 25, 24 have holding holes 25b, 25c, 24b having inner diameters smaller than the outer diameters of the protrusions 52d, 52e, 51d, 51e at positions corresponding to the protrusions 52d, 52e, 51d, 51e of the end face caps 52, 51. , 24c are formed, and the projections 52d, 52e, 51d, 51e are tightly inserted into these holding holes 25b, 25c, 24b, 24c, and by the same action as the O-ring 26 (see FIG. 5) described above. The end caps 52, 51 are detachably held on the outer pieces 22, 21.

FIG. 7 is an exploded perspective view showing a structure in which the end piece cap 52 is held by the outer piece 22 having the holding member 27 divided into two holding member pieces 27A and 27B.

The outer piece 22 shown in FIG. 7 has a holding member 27 fitted in a hollow inner space 22e. The holding member 27 is composed of a holding member piece 27A and a holding member piece 27B formed of an elastic material such as silicone and divided into two pieces in the vertical direction in the figure. The two holding member pieces 27A and 27B are brought into close contact with each other in the direction of the arrow shown to form a holding hole 27a into which the protrusion 52d of the end face cap 52 is inserted and a holding hole 27b into which the protrusion 52e is inserted.

The end surface cap 52 has large diameter portions 52f and 52g that are thicker than the outer diameters of the protrusions 52d and 52e at the tips of the protrusions 52d and 52e.

A large diameter hole 27c having an inner diameter larger than that of the holding hole 27a is formed on the inner side of the holding hole 27a, and a larger diameter hole 27d having an inner diameter larger than that of the holding hole 27b is formed on the inner side of the holding hole 27b. There is. The inner diameters of the holding holes 27a and 27b are larger than the outer diameters of the protrusions 52d and 52e, but smaller than the large diameter portions 52f and 52g.
