Description

  The present invention relates to a wristwatch belt.

  Generally, the length of the wristwatch belt is adjusted by fixing it with a buckle so as to fit around the wrist of the wearer. However, with the buckle, the length can be adjusted only stepwise at the position of the hole provided in the belt, and there is an excessive gap between the wrist and the wrist is tightened more than necessary. There was a case where the feeling of wearing the belt could not be obtained. In addition, the operation of passing the belt through the buckle with one hand and inserting and fixing the pin into the hole requires a knack and time, and is problematic.

  In order to realize a good wearing feeling with a wristwatch belt, it is necessary that the length of the belt is appropriately adjusted. For this reason, various types of shape devices have been proposed for a wristwatch belt so as to impart ease of length adjustment and ease of wearing (see, for example, Patent Document 1 to Patent Document 3). ).

  For example, the wristwatch band disclosed in Patent Document 1 forms an expansion and contraction mechanism, and the band itself expands and contracts according to the size and movement of the wrist. Therefore, fine adjustment of the band length is unnecessary, and a good wearing feeling Can be granted. In addition, the wristwatch belt disclosed in Patent Document 2 has a length slightly smaller than the case of fixing with a buckle because a desired position of a belt composed of a number of spheres is sandwiched and fixed with a fastener. Adjustment is possible, and a good wearing feeling can be imparted. Furthermore, since the wristwatch belt disclosed in Patent Document 3 is fixed using a snap, the belt can be easily attached (detached).

  However, for example, the wristwatch band disclosed in Patent Document 1 is easy to obtain a good wearing feeling, but since it is configured to be fixed with a buckle, the wearing operation is complicated as in the past, and a complicated band There existed a subject that manufacturing cost became high by structure. Also, the wristwatch belt disclosed in Patent Document 2 has a problem that the attaching operation of the fastener is complicated and the manufacturing cost is high due to a complicated band configuration requiring a large number of spheres. Further, the wristwatch belt disclosed in Patent Document 3 has a complicated length adjustment that is separately performed by attaching and detaching the rivet member, and the length adjustment can be performed only in steps as in the conventional case, so that a good wearing feeling can be obtained. There was a problem that it could not be obtained.

  As described above, the conventional wristwatch belt does not satisfy the ease of length adjustment and the ease of wearing at the same time. Therefore, it is easy to wear and does not realize a good wearing feeling. .

  Hereinafter, a wristwatch belt according to an embodiment of the present invention will be described in detail with reference to the drawings.

  [Embodiment 1] First, FIG. 1 is a perspective view showing an appearance of a wristwatch belt according to Embodiment 1 of the present invention. The wristwatch belt according to the first embodiment mainly includes an upper belt portion 10 and a lower belt portion 12 and a base portion 30 to which the belt is connected.

  The upper belt portion 10 is a belt having a continuous wave shape bent from the base portion 30 toward the tip, and a plurality of protrusions 11 are formed at positions corresponding to the wave shape bends in the vicinity of the tip 10a. ing. Further, the lower belt portion 12 is a belt having a configuration in which a corrugated bent shape is continuously formed in a tip direction opposite to the upper belt 10, and corresponds to a corrugated bend point in the vicinity of the tip 12a on the opposite side. A plurality of holes 13 sized to fit the protrusions 11 are formed at the positions.

  The base unit 30 is a base on which the watch body 40 is placed. The base portion 30 is formed with a fitting hole 33 (see FIG. 3) having an upright wall 31 formed so that the watch body 40 can be fitted in accordance with the outer shape of the watch body 40 (circular in the case of the present embodiment). ing. Further, a crown 41 of the timepiece main body 40 fitted into the fitting hole 33 and a fixing screw 50 screwed from the side surface of the upright wall 31 to fix the timepiece main body 40 and the base portion 30 are protected on the base portion 30. A protective wall 32 is formed on the outside of the upright wall 31.

As shown in the figure, the upper belt portion 10 and the lower belt portion 12 are wound around the wrist, and the lower belt portion 12 is overlapped on the upper belt portion 10 so that the corrugated bent shape is matched. When pressed, the protrusion 11 formed in the vicinity of the distal end 10a is fitted into the hole 13 formed in the vicinity of the distal end 12a, and the upper belt portion 10 and the lower belt portion 12 are closely attached and fixed. Since the outer diameter of the hole 13 is smaller than the outer diameter of the protrusion 11, the inserted protrusion 11 is difficult to come off. In addition, since the wave-like bent shape can be overlapped if shifted by one period, the belt can be fixed while appropriately adjusting the length of the wristwatch belt. Further, since the upper belt portion 10 and the lower belt portion 12 are wave-like bent shapes as shown in the figure, the belt itself has elasticity. Therefore, even if the position where the upper belt portion 10 and the lower belt portion 12 are overlapped is slightly shorter than the appropriate position, a good wearing feeling due to the stretchability, that is, a feeling of fitting that fits properly on the wrist is obtained. It is done.

  FIG. 3 is a schematic diagram for explaining a state in which the watch main body is detached from the wristwatch belt according to the first embodiment of the present invention. As shown in the figure, the insertion hole 33 having the upright wall 31 of the base portion 30 is slightly smaller than the outer shape of the watch body 40 (circular in the case of the present embodiment) so that the watch body 40 can be inserted. Is formed. The watch body 40 is fitted from the back side of the base portion 30, but a hole 34 for receiving a crown protruding from the watch body 40 is formed on the side surface of the upright wall 31. Similarly, a hole 35 for screwing a fixing screw 50 for fixing the timepiece main body 40 and the base portion 30 is also formed on the side surface of the upright wall 31. Further, a protective wall 32 for protecting the crown and the screwed fixing screw is formed outside the upright wall 31. In this embodiment, the entire base portion 30 is designed in a rounded triangular shape. .

  By the way, the wristwatch belt according to the first embodiment of the present invention is formed by integrally molding a resin material having good flexibility and stretchability by injection molding or the like, is easy to attach and detach, and can provide a good wearing feeling. The belt can be easily manufactured at low cost.

A substantially trapezoidal portion 23 having a cross-sectional shape that can be fitted into the groove portion of the concave portion 21 is formed.

  The base unit 30 is a base on which the watch body 40 is placed. Since the structure of the base part 30 is the same as that of the first embodiment, detailed description thereof is omitted.

  As in the first embodiment, the lower belt portion 20 and the upper belt portion 22 are formed in a wave-like bent shape so that the width increases toward the base portion 30, and the watch is worn. Increases the strength near the boundary between the belt and the base, where bending force is sometimes applied.

  FIG. 5 is a schematic diagram for explaining a cross-sectional shape of the wristwatch belt in the vicinity of the front end of the belt and the state of insertion in the second embodiment of the present invention. When the lower belt portion 20 and the upper belt portion 22 are wound around the wrist, and the upper belt portion 22 is overlapped on the lower belt portion 20 so as to match the corrugated bent shape, both sides are pressed, and the vicinity of the tip 22a. The substantially trapezoidal portion 23 formed in the shape is fitted into the concave portion 21 formed in the vicinity of the tip 20a, and the lower belt portion 20 and the upper belt portion 22 are in close contact and fixed. Since the cross-sectional shape of the concave portion 21 is a substantially trapezoid with the bottom expanded, the fitted substantially trapezoidal portion 23 is difficult to come off. In addition, since the wave-like bent shape can be overlapped if shifted by one period, the belt can be fixed while appropriately adjusting the length of the wristwatch belt. Further, since the lower belt portion 20 and the upper belt portion 22 are corrugated and bent as shown in the figure, the belt itself has elasticity. Therefore, even if the position where the lower belt portion 20 and the upper belt portion 22 are overlapped slightly deviates from the appropriate position, a good wearing feeling due to the stretchability, that is, a fit feeling that fits properly on the wrist. can get.

  By the way, the wristwatch belt according to the second embodiment of the present invention is also formed by integrally molding a resin material having good flexibility and stretchability by injection molding or the like, and is easy to attach and detach, and a good wearing feeling can be obtained. The belt can be easily manufactured at low cost. The base portion 30 and the belts 20 and 22 are preferably not formed in a straight line but are formed so as to form a predetermined angle (specifically, so as to bend toward the back side of the watch body 40). This is because when the watch is worn, the belt can be easily overlapped with the hand opposite to the wearer.

  As described above, according to the wristwatch belt of the second embodiment, the substantially trapezoidal portion 23 is fitted into the concave portion 21 simply by overlapping and pressing the vicinity of the tip of the upper belt portion and the lower belt portion. Since it can be fixed, the wristwatch can be easily attached. Further, even when the overlapping position is slightly shorter than the appropriate position according to the wrist circumference, a good wearing feeling can be obtained due to the stretchability of the belt itself.

  In the above embodiment, an example in which the outer shape of the watch body is a circle has been described. However, the present invention is not limited to this.
