た。 Conventionally, this type of tip structure has adopted a tip with a winding part integrally provided at the center of the tip side of the board, and engaging pieces integrally provided at both ends of the tip side, and the tip board is attached to the watch band. It is attached to the back of the tip by projection welding. On the other hand, one type of metal band is a band whose top surface is finished after the band body is formed, and then an etching-like pattern is added by stamping. Figure 4 shows the structure of such a band. The top plate part 1 has the same upper surface finish and stamping as the band 2, and with the top plate part 1 and the upper surface of the tip 3 in close contact, the upper part of the winding part 4 of the tip 3 is inserted. The two are welded together using a bolt 4a, and then the rear surface of the tip of the band 2 is welded using a projection 5a of the base plate 5 of the tip 3 to connect the tip and the band. However, as the watch case becomes thinner, the watch band also becomes thinner, and the thickness of the top plate 1 is also thinner, so that an indentation 1a is sometimes formed on the surface of the top plate 1 during projection welding. The tip piece had already been stamped with an etching-like pattern, and it was difficult to remove the impression, which could spoil the appearance.

ことを特徴とするものである。 In accordance with the above object, the watch band tip structure according to the present invention has a rear end surface that comes into close contact with the tip surface of the metal watch band, and a tip piece with a step formed on the back surface and a spring bar inserted into the step. A winding portion that engages with the watch case, a pair of engagement pieces that engage with the watch case, and a tip having a substrate formed with a plurality of projections protruding from it, and the back side of the band and the tip piece are provided on the substrate. The band is characterized in that a tip piece and tip are attached to the tip of the band by welding to the tip using a projection.

成されている。 As shown in FIGS. 1 and 2, the first part 6 is a base plate 7 on which two pairs of welding projections 7a and 7b are protruded at a constant interval, and a winding part into which a spring bar is inserted. 8, and case (not shown)
It consists of a pair of engaging pieces 10 that come into contact with the back side of the. The band body 11 is a metal band commonly known as a raft band, which is constructed by connecting connecting pieces, and after finishing the upper surface, an etching-like pattern is formed by stamping. The tip piece 12 is made by cutting a solid metal plate material, and has a stepped part 13 formed in the band width direction on the back side, and a top plate part 15a and a thick part 15b.
The rear end surface 14 is formed to be in close contact with the tip of the band. Its upper surface 15c is band 1
The groove 16 is finished and stamped to match the upper surface of the band 1 and has a groove 16 of the same shape as the band, so that it has the appearance of being part of a band.

ンドの先端部が構成される。 As shown in FIG. 3, the tip structure configured in this manner is such that the outer surface of the winding portion 8 of the tip 6 is brought into close contact with the stepped portion 13 of the tip piece 12, and the tip surface of the band 11 and the tip piece 1 are brought into close contact with each other.
With the rear end surface 14 of the tip 6 in contact with the rear end surface 14 of the tip 6, the tip 6 and the tip 12 are welded together using one pair of projections 7a provided on the board.
Attach the thick wall portion 15b of the Next, the next board 7
The back side of the band and the substrate 7 are welded together by the other pair of projections 7b, and the tip and tip piece are attached to the band 11, forming the tip of the band.

となつている。 As is clear from the above, according to the present invention, the tip is attached by projection welding the base plate to the back surface of the thick part of the tip and the back surface of the band, respectively, so that the projector can be attached depending on the thickness of the top plate. It has a tip structure that does not easily leave impressions from excision welding and has an excellent appearance.

しかも、先駒は、ムク材から作つたものである
から、高級感のあるバンドを提供することができ
る。 Moreover, since the tip piece is made of solid wood, it is possible to provide a band with a high-class feel.
