Description

[Detailed Description of the Invention] This invention relates to a watch band in which a plurality of pieces of one type formed by punching and bending a single metal plate are interconnected.

Conventionally, a wide variety of watch bands have been put into practical use depending on their purpose and use, but there is a particular need for them to be able to be manufactured at low cost without impairing the design.

This idea was made in view of the above circumstances, and its purpose was to reduce the number of manual assembly parts, to construct a watch band with only one type of piece, and to reduce costs. , and give the image of a luxury product in terms of design.

This invention will be described in detail below based on embodiments shown in the drawings.

In this invention, a watch band is constructed by connecting a plurality of pieces 1 of one type as shown in Figs. It is formed by punching out as shown in FIG. 5 and folding it back as shown in FIG. 6, and the reference numeral 2 in the figure is the top plate.

An engagement hole 3 (or an engagement groove) is formed at the end of the top plate 2 in one direction of connection (left direction in FIGS. 1 to 5), and an end of the top plate 2 in one direction of connection is formed with an engagement hole 3 (or an engagement groove). , as will be described later, is folded back toward the back side (approximately 180° in FIG. 6), so that it is placed in a recessed position corresponding to the thickness of the top plate 2,
A connecting piece 4 facing the engagement hole 3 is formed on the back side of the top plate 2, and a connecting piece 4 protruding in the other direction is formed at the end of the top plate 2 in the other direction (right direction in FIGS. 1 to 5). A winding piece 5 is formed, and this winding piece 5 is wound around the connecting piece 4 of another piece 1 from the front side to the back side, so that the winding piece 5 can be wrapped around the adjacent piece 1.
．． 1 is in a connected state.

Furthermore, as shown in FIGS. 1 to 6, folded pieces 6 and 7 are formed at both ends of the top plate 2 in the connection direction, respectively, and project from both ends and are folded back toward the back surface. 7 forms both side portions of the piece body 1 along the connecting direction.

That is, after the piece 1 is punched out from a metal plate as shown in FIG.
Fold the other folded pieces 7, 7 on the back side of both folded pieces 6, 6, bend them at 90 degrees from C, and wrap the winding pieces 5 by 45 degrees from the folded lines d and e, respectively. °
Then, bend it 90 degrees to the state shown in FIG.

At this time, the bending angle from the bending line d is not necessarily limited to 45°, but may be, for example, 30°.

Next, the piece body 1 in the state shown in FIG.
By hooking them one after another, they become interconnected.

If the pieces 1 in this state are strongly pressed in the thickness direction, the back side of the pieces 1 becomes flush with each other and the connected state is stabilized, as shown in FIGS. 3 and 4.

In this way, in this invention, each piece body 1 is formed by a pressing operation from a metal plate as shown in FIG.
The watch band can be shaped by the three steps of manual fitting and then pressing in the thickness direction. By cutting and polishing the side surfaces into the desired shape, the boundaries become less noticeable, giving the impression of being cut from thick material (so-called solid wood), and enhancing the design effect.

On the other hand, FIG. 7 shows a piece body 11 showing another embodiment of this invention.
The engagement groove 13 corresponds to the engagement hole 3 shown in FIG. The folded pieces 16 are formed respectively, and have a similar function to the embodiment shown in FIGS. 1 to 6.

In addition, the folded piece 16 in this embodiment is made to protrude from the connecting end of the top plate 2 in one direction and not to protrude from the other direction end, so that the gap between the winding piece 5 and the folded piece 16 ( The gap in the band width direction on the back surface of the bridge body 11 can be reduced to zero.

Other parts that are common to the embodiments shown in FIGS. 1 to 6 are given the same reference numerals and their explanations will be omitted.

As detailed above, this invention is constructed by interconnecting a plurality of pieces of one type pressed from a single piece of material, so it has a very simple structure. Other than the manual work of hooking the wrapping piece to the connecting piece,
It can be processed by press work, reducing processing and assembly time.
It is possible to reduce costs, and since the winding piece inserted into the engagement hole or engagement groove is wrapped around the connection piece recessed by the thickness of the top plate and folded piece, the piece body On the front and back sides of the piece, there are almost no visible seams between the pieces and other pieces, and the designs on the front and back sides are similar, as shown in Figures 1 and 2, for example. ,
It has the impression of so-called solid wood, has a high design quality, and has excellent effects such as being able to give an image of a high-class product.

Claims (1)

[Scope of utility model registration request] It is made up of a plurality of pieces of one type connected together, and this piece has a top plate with an engagement hole or an engagement groove formed at one end of the connection, and a top plate that is bent on the back side of the top plate. The connecting piece facing the retaining hole or retaining groove at a position recessed by the thickness and the connecting piece of the top plate protrudes from the end in the other direction and wraps around the connecting piece of the other piece so that the pieces are mutually connected. A watch band characterized in that it is composed of a wrapping piece that is connected to the front plate, and a folding piece that is sequentially folded back from the end of the front plate in the connecting direction to the back side and overlapped to form a side part of the piece body. .
