Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a watch band structure.

[0002]

[Prior art]

 Conventionally, as a general structure of this type of core type band structure, there is a spot center type shown in a perspective view of FIG.

A hollow tubular band piece 20 formed by spot welding is inserted into the core 10 of the mesh of the band to form a band body. Since the mesh core is formed, the band body has good flexibility. And so on.

[0004]

[Problems to be solved by the device]

 However, in this conventional structure, generally, the center core and the band piece cannot be fixed, and a stopper piece is provided at the front end and the rear end to prevent the stopper from coming off, so that the band piece can be stopped at any position. It had the drawback that only Nakadome could be used, and even if the core and band pieces could be fixed, the flexibility of the mesh core would be impaired due to the fixation.

An object of the present invention is to eliminate the above-mentioned drawbacks and to enhance the commercial value of the timepiece band such that the length can be easily adjusted without impairing the advantage of good flexibility. It is an attempt to provide structure.

[0006]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the above object, an elastic core band 2 having a plurality of locking holes 2a in the middle is fixed to the tip piece 1, and the core band 2 is attached to the hollow portion 3a of the band piece 3. Insert the locking member 4 having a diameter larger than the size of the locking hole 2a into the locking hole 2a to make a part of the core band 2 larger than the inner diameter of the hollow portion 3a. The band pieces 3 are sequentially connected by preventing the existing band pieces 3 from retreating, and a removable clasp 5 is attached to the rear end to the core band 2 to form a band. By removing the disengagement locking member 4 from the locking hole 2a, the band piece 3 can be retracted, and the band piece 3 is sequentially removed and the core band 2 is cut at a portion of a predetermined length to adjust the length. It is characterized in that the body 5 is attached. Further, the protruding portion 2b may be formed above or below the core band 2. Further, the protrusion 4a may be formed above or below the locking member 4.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view of a main part of the watch band of the present invention, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is a sectional view showing a positional relationship in which a rear inner clasp is removed. FIG. 4 is a sectional view showing the positional relationship in which the band piece is further removed from FIG. 3, and FIGS. 5 and 6 are sectional views of other embodiments.

Reference numeral 1 is a tip piece to which a core band 2 is fixedly attached.

Reference numeral 2 is a core band, and a plurality of locking holes 2a are provided in the middle portion. In some cases, the protrusion 2b may be provided above or below the locking hole 2a.

Reference numeral 3 is a band piece, in which a hollow portion 3 a to be inserted into the core band 2 is provided.

Reference numeral 4 denotes a locking member which is inserted into the locking hole 2a so that a part of the core band 2 is made larger than the inner diameter of the hollow portion 3a so as to prevent the band piece 3 located in front from retracting. Has a diameter larger than that in the thickness direction or has a protrusion 4a. When the protrusion 2b is provided above or below the locking hole 2a, the thickness is the same in the thickness direction of the locking hole 2a.

Reference numeral 5 denotes a clasp which is attached in such a manner that the rearmost band piece 3 is prevented from retreating and the core band 2 is removable.

Next, a method of adjusting the length of the band structure according to the present invention will be described. By removing the clasp 5 and removing the locking member 4 from the locking hole 2a, the band piece 3 can be retracted, the band piece 3 is sequentially removed, and the center band 2 is cut at a predetermined length. The length can be adjusted by adjusting the length and attaching the middle clasp 5 again.

[Effect of device]

 As described above, according to the present invention, a dedicated cutting jig is not necessary without impairing the advantage of good flexibility, and it is easy to extend the length by simply putting the locking member in and out of the locking hole of the core band. It is possible to increase the product value such as the degree of adjustment. Further, the effect can be further enhanced by providing the core band with a protrusion or by providing the locking member with a protrusion.
