JPH0246808A - Stopper for watch strap - Google Patents

Abstract

PURPOSE:To enable a watch to be comfortably worn even when the thickness of an arm changes and simplify the putting on/off thereof at the time of putting on/off a watch by loosening/tightening the band which is inserted into the strap inserting hole of a strap stopper by the opening/closing of a pressing lever rotatably pivoted by the strap stopper. CONSTITUTION:First, with a pressing level 4 opened, the wrist is inserted into the ring of a strap 1 which is widely opened while shifting a strap stopper 3 in the arrow A direction and then, the strap stopper 3 is shifted in the arrow B direction to fitly wind the ring of strap 1 around the wrist. Then, as the pressing lever 4 is closed, the strap 1 inserted in a strap inserting hole 3a is tightened by means of a pressing portion 4b which is eccentric to a supporting shaft 4a, and the strap stopper 3 is held by the strap 1 without slipping due to the frictional force at that time, preventing the band from loosening. On the other hand, at the time of removing the strap 1, the pressing lever 4 is opened and the strap stopper 3 is slided to easily enlarge the ring of the strap 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a watch band stopper that can be freely adapted to the thickness of a bowl and that can be easily attached and detached.

[Conventional technology]

The length of the band attached to a conventional wristwatch is constant to some extent, as the wristwatch is worn directly on the wrist of a person. Even so, taking into account the variations in human body shapes, the current length is about 1.2 times the length that is sufficient for use by a normal person.

[Problem to be solved by the invention]

However, when you normally wear a watch directly on your wrist, for example, when you are skiing, you may want to wear the watch over your ski gloves and check the time while skiing. Since it is worn on the arm, the circumference of the arm is usually about 1.3 when worn on the arm.
It will more than double.

In such cases, if you prepare a slightly longer band, you can wear it over ski gloves, but if you are carrying it normally, the disadvantage is that if you do not use a normal length band, there will be too much excess and it will be difficult to wear it. Another drawback is that the band overlaps with the watch, making it difficult to see the time.

On the other hand, if bands of different lengths are used for normal carrying and skiing, they must be replaced every now and then, which is very troublesome.

Also, since the length of a normal watch band is set according to the greatest common divisor of humans, it is usually a little longer, about 1.2 times, so that it is just right for people with thick wrists, but if If a person with thick wrists wears gloves and sells a band long enough to wear a watch on top of it, then when a person with thin hands wears it normally, the band becomes too long, which reduces the marketability of the product. It has the problem of being damaged.

In order to solve the above-mentioned problems, the present invention has been developed so that even if the thickness of the arm changes drastically due to, for example, putting on a glove, the watch can be comfortably worn by adjusting the buttons, and the band can be easily attached or removed when the watch is put on or taken off. The purpose of the present invention is to provide a stopper for a watch band that can be attached and detached.

[Means to solve the problem]

In order to achieve the above object, the present invention has a substantially rectangular planar shape, provides a band attachment part for attaching one end of the band to one side wall of the band in the transverse direction, and forms an opening on the upper surface side.
A pair of bearings or support shafts are disposed on the upper surface side at opposing positions parallel to the width direction of the band on opposite side walls of the opening, and a band insertion hole into which the band is inserted is formed in the side wall. a band stopper, and a support shaft that is inserted into the opening of the band stopper and rotatably pivots on a bearing or support shaft provided at the tip of the lever part on both sides of the opening of the band stopper; It consists of a pressing lever having a bearing and an eccentric pressing part formed on the support shaft or the bearing, and supports the band inserted into the band insertion hole of the band stopper by opening and closing the press lever pivotally supported on the band stopper. It is characterized by tightening.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Figures 1 to 5 show one embodiment of the present invention, Figures 1 and 2 are sectional views and front views of main parts showing the mounting structure of the watch band, and Figure 3 is a stopper of the watch band. The side view of the tool, and FIGS. 4 and 5 are perspective views showing the open and closed states of the pressing lever of the stopper.

The structure of the constituent members will be explained using FIG. 1 to FIG. 5.

1 is a band, and both ends 1a of the band 10 are shown.

1b is formed with spring through holes 1c and 1d through which the spring rod 2 can pass.

2 is a spring bar, which connects band 1 and watch case 5 or band 1.
This is an attachment member for attaching the band stopper 3.

Reference numeral 6 denotes a band stopper, which has a substantially rectangular planar shape and has a band insertion hole 6a formed in a side wall into which the band 1 is inserted, and a band attachment device for attaching one end 1a of the band 1 to one side wall in the short direction of the band. A section 3b is provided. Further, an opening 6C is formed on the upper surface side of the band stopper B, and a pair of bearings 3d are provided on the upper surface side at opposing positions parallel to the width direction of the band on opposite side walls of the opening 3C. ing.

Reference numeral 4 denotes a pressing lever 1, and a supporting shaft 4a rotatably attached to the bearing 3d of the band stopper B is provided at the tip of the lever portion, and a pressing portion 4b eccentric to the supporting shaft 4a is formed on the lower surface side. has been done. The pressing lever 4 is connected to the support shaft 4a and the bearing 3.
d, the band stopper 6 is openably and closably disposed in the opening 6C of the band stopper 6, and in the closed state, the pressing part 4b pushes the band 1 inserted through the band insertion hole 3a against the band stopper B. It is designed to be pressed and held.

Reference numeral 5 denotes a watch case, and spring bar support holes 5a and 5b for supporting the spring bar 2 are bored at both ends thereof.

Then, the end 1b of the band 1 is attached to one end of the watch case 5 with the spring bar 2, and the other end 1a of the band 1 is inserted into the band insertion hole 3a of the band stopper B, and the other end 1a of the band 1 is inserted into the band insertion hole A of the band stopper B. It is folded back by a spring bar 2 fixed to the other end and attached to the band attachment part 3bK of the band stopper B by the spring bar 2.

Next, a method of operating the stopper of the watch band will be explained. First, with the pressing lever 4 open, press the band stopper 3.
While shifting the band in the direction of arrow A, pass the arm through the widened loop of band 1, and then shift the band stopper 3 in the direction of arrow B to tightly wrap the loop of band 1 around the arm. Then, when the pressing lever 4 is closed, the band 1 inserted into the band insertion hole 6a is tightened by the pressing part 4b eccentric to the support shaft 4a, and the band stopper 6 is prevented from sliding against the band 1 due to the frictional force at this time. This prevents the band 1 from loosening. On the other hand, if the band 1 is removed, the ten rings of the band can be easily increased by opening the pressing lever 4 and sliding the band stopper 3.

With the above configuration, the adjustment range of the winding length of the band 10 can be adjusted to a length that is approximately twice the minimum winding length (by lengthening the folded portion of the band 1).

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the length of the band can be easily and freely adjusted by moving the band stopper to an appropriate band position according to the thickness of the bowl. Further, the band can be easily loosened and tightened with respect to the band stopper simply by opening and closing the pressing lever, and the band can be worn comfortably.
