Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a leather watch band with a folding snug that forms a closed loop when the clasp is open.

(Prior art) This woodcutter's watch band has been extremely widely used,
2 called folding fasteners or unfolding power fasteners
Equipped with a fastener consisting of two or three elements. Leather bands are usually fixed at different times via a spring bar.

When worn on the wrist, this known watch band forms an angle to some extent, which poses a problem in its appearance in relation to the watch. In addition, the loop formed by the watch band often closes unintentionally when the fastener is released, so it is often difficult to put your hand through the band since it is worn on your wrist. The leather must be strong and thick enough to withstand the tensile force of 4 when closing the metal fittings. This tension tends to cause the watch to assume a linear shape between the watch and the fastener.

(Purpose of the invention) An object of the present invention is to solve these problems.

(Aspects and Effects of the Invention) The watch band of the present invention that achieves this purpose has one end that is
It is characterized by having a core feather made of two n'' flexible thin plates fixed to the llJtl with one weight and connected to a fastener at the other end and wrapped in leather.

By connecting the flexible core material to this weight on the watch side, the tensile resistance of the watch band is ensured, and at the same time, the looseness formed by the watch band when the fastener is released is maintained in an open state. , a harmonious curve that does not curve into bubbles from the open side can be obtained. Preferably, the core is very thin and extremely flexible so that there is little resistance when closing the fastener. Because it is extremely thin, the thin plate naturally does not increase the thickness of the watch band, but rather has a high resistance so that it can be used in conjunction with extremely thin leather, thus reducing the final thickness of the watch band. It is a traditional leather watch with one band or less than seven.

Therefore, it is possible to realize a durable watch band that is light and has a thin appearance.

(Embodiment) An embodiment of the watch band of the present invention will be described below with reference to the accompanying drawings.

The core of the watch band consists of two thin sheets 1.2 of beryllium bronze with a thickness of 0.15+mm. One end of the thin plate is drilled into the metal forming part of the watch side, for example brass, and welded.

The other end of the thin plate 1.2 is bent in such a way as to form a recessed tubular ferrule 4 which connects the watchband to the clasp 5. Wrap the elastic thin plates 1 and 2 with the leather 6 of time it ttt++ ◎□ The leather is glued to the thin plates.

The fastener 5 is of the deploying buckle type or the double-needle folding type, and connects at the end of its central part 7 two arms 8.9 which are folded and locked onto said central part 7.・When attaching the watch band to the fastener, the part is covered by the cover plate 10.

Due to the embedded metal plates 1 and 2 and the elasticity of these thin plates themselves, when in the open state, the N1 band maintains the deployed position shown in FIG. 1 or tends to return to this position. Since in the fully opened state the plates 1, 2 can have a more or less pronounced initial curvature, the elastic force alone is sufficient to maintain the watchband in the deployed position shown in FIG.
There is no possibility of excessive tensile forces acting on the fasteners or excessive stress acting on the implantation area. Since the watch band has this tendency to develop, it is easy to wear it around the neck and remove it. The use of elastic core also gives the 61' band a harmonious appearance and curve when made of leather.

It goes without saying that within the scope of the present invention, the embodiment of Yuzu is capable of 5J. For example, other metals, such as steel, may be used as the material for the sheet metal, and it may also be fixed to the watch side, in particular to the case, in other ways, for example by means of screws. The ferrule 4 may be attached separately.

The flexible sheet may also be made of a synthetic material other than metal, such as nylon. The advantage of synthetic veneers is that they can be manufactured by molding, which increases the adhesion of the leather to the veneers.
