Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a watch band having a press groove in the middle of each winding piece.

<Problems that this invention aims to solve> Conventionally, when forming a stepped groove as an accent on the upper surface of the middle part of each plate-wound piece that makes up a plate-wound watch band, the presence of the core plate made it extremely shallow. Moreover, since the winding plate was thin, it deformed and the gaps between the grooves of each piece were uneven. In particular, when forming a stepped groove on the middle upper surface of a board winding piece whose upper surface is round-shaped, deformation occurs and irregularities occur. The present invention attempts to solve these problems.

<Structure of the invention> The present invention consists of a core plate curved in the non-axial direction and a winding plate wound around the core plate, and a winding piece whose upper surface is in the shape of a round shell is straddled by connecting pieces having legs at the four corners. In the watch band that is connected by fitting, an endless recess is provided in the non-axial direction in the middle of the core plate, and an endless press groove that fits into the recess is provided on the upper surface of the middle part of the winding plate. This is a feature of the watch band.

<Example> Examples will be described below based on the drawings.

An endless concave portion 9 is formed in a step in the non-axial direction on the upper surface of the intermediate portion of the core plate 1 which is curved convexly in the non-axial direction. The core plates 1 are arranged in parallel and a connecting piece 6 is fitted between each core plate 1. The connecting piece 6 is U-shaped in side view and has legs 5 at four corners in the axial direction. Reference numeral 2 denotes a winding plate curved in a non-axial direction, which is tightly wound around each core plate 1 to form a winding piece 4 with a top plate 7 having a shell-shaped shape, and at the same time, one half of the leg 5 is wound tightly around each core plate 1. Each of the winding pieces 4 is enclosed in a connecting groove 3 to connect the board winding pieces 4.

Next, with the plate winding pieces 4 connected, an endless press groove 8 is formed on the upper surface of the intermediate portion to fit into the recess 9 in contact with the surface.

<Effects of the invention> As described above, in the present invention, the press grooves on the upper surface of the middle part of each round-shaped plate winding piece are formed based on the endless grooves provided in the core plate. The grooves can be formed deep in the concave groove portion of the core plate, and deformation does not occur, and furthermore, the press grooves are endlessly connected between the winding pieces, thereby preventing irregularities.
