Description

[Detailed Description of the Invention] This invention relates to a so-called presslet type watch band connection device, which is made up of parallel wheel pieces whose circular shape in plan view is square.

The purpose is to provide a new connecting device that does not unnecessarily loosen even when tensile pressure is applied in the connecting direction, and that is easy to attach and separate.

Conventionally, as shown in Fig. 6, a winding plate 8 is placed over and wound between the connecting shafts 2 of the piece 1, or as shown in Fig. 1, a half plate 9 is placed over it, and a screw 10 is inserted from below to secure it. In addition, although not shown, a method is adopted in which the upper and lower curved ring bodies are fitted from above and below, but in the first method, when tensile pressure is applied in the connection direction, When the winding plate 8 returns and opens, there is a drawback that the pieces become loose or come off, and 2
The second method has the disadvantage of splitting the pieces if the screw 10 loosens, falls off, or is lost, and the third method is similar to the first method because it is fitted with a circular ring, so tensile pressure in the connection direction is applied. Then, there is a drawback that the ring returns to open and loosens between the upper and lower wheels, causing them to come off.

The present invention eliminates these drawbacks, and will be described in detail below with reference to the drawings of the embodiments.The pieces constituting the 1/ri presslet type band include circular rings and square rings in plan view.

Reference numeral 2 denotes a connecting shaft portion formed with a thin pattern on both sides of the piece 1.

Reference numeral 3 denotes a lower end ring body formed of a spring plate so as to be compressible, and having an elliptical shape with a notch in side view, the ring body 3 fits between the shaft portions 2 of the adjacent pieces 1 as a backing and straddles the space.

Reference numeral 4 denotes an upper end wheel body formed to a size to fit into the lower end wheel body 3, and as shown in Fig. 4, it has a rigid structure with an inverted E-shape in side view and a rigid structure. It is formed by providing an inwardly facing leg part 5 to be attached at the lower part, or as shown in FIG. is provided and attached as a rigid structure to the lower end ring body 3 to form a band of a predetermined length.

In addition, 7 in the figure is a hanging wall for preventing lateral slippage provided on both sides of the intermediate portion of the upper end wheel body 4 in the connection direction, and is fitted between the stepped portions 6 provided on both sides of the end portion of the lower end wheel body 3. This is how it was done.

As described above, in the present invention, the upper end ring body 4 has a rigid structure, so even if tensile pressure is applied to the band in the connection direction when wearing and removing it, the ring body 4 will not deform, especially stretch and open. It is possible to maintain the connected state and prevent any loosening or separation between the pieces.

In addition, since the lower end wheel body 3 is made of a spring plate that can be compressed, the upper end wheel body 4 can be easily attached to the upper end wheel body 4 by pressing the wheel body 3, and the housing can be removed. If the band length is long, remove it and insert 1 piece 2.
The wearer can easily take one piece and adjust the band length by himself/herself.

In this way, the present invention has the effect of prolonging the life of a pressed thread type watch band and providing a new connecting device that allows the length to be freely adjusted.
