DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band (or belt) having an engaging groove at an end thereof, and more particularly to a band for a watch band, a band for pants or a skirt, a band for a bag or shoes. It is about structure.

[0002]

2. Description of the Related Art When a portable information terminal such as a watch, a bracelet, a personal computer, a blood pressure monitor, pants or a skirt, etc. is attached to an arm, a leg, a torso or the like, the circumference of the band is usually adjusted by a band. It is attached and detached.

[0003] However, it is not easy to perform the above-mentioned band attaching / detaching operation with one hand, and it is extremely difficult to adjust the band particularly at the back portion where it is difficult to visually recognize the band or at night or in a dark place.

[0004] In a watch band, a middle clasp is provided at an intermediate portion of the band, and the band is attached or detached with one hand by operating the clasp or a fingertip.

[0005] However, the attachment and detachment work with the middle fasteners is difficult for persons with short nails or those with weak power to operate, and in order to improve this, the structure of the middle fasteners becomes complicated. have.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a band having a simple structure, which can be quickly and easily attached and detached, and which has a simple structure.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a perimeter is adjusted by sliding both ends of a band having an engaging projection at one end and an engaging recess at the other end. In a band that is connected in a ring by the engagement of both engagement portions,
In a state in which the engaging projections are locked in the engaging recesses, the other end can freely advance with respect to the one end, but cannot be retracted. It is characterized in that a pair of hooks which can be pulled by one fingertip are provided.

[0008] Preferably, the engaging portion is a projection provided on the outer surface of the band. It is preferable that one of the engaging portions is a slide guide provided along one of the engaging portions. It is preferable that the hook portion is a through hole extending from the outer surface to the inner surface of the band.

[0009]

When the fingertip of one hand is hung on the pair of hooks and pulled together, both ends of the band are slid so that the peripheral length of the band can be adjusted to be short. In this state, the two engaging portions are locked, and the band is not loosened. On the other hand, when the locking of the two engaging portions is released, the other end portion retreats with respect to the one end portion, and the band naturally relaxes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a band according to the present invention will be described below with reference to the drawings, taking a watch band embodiment as an example.

FIG. 1A is a perspective view showing a state in which the end of the band 10 is engaged, and FIG. 1B is a longitudinal sectional side view in the circumferential direction. In addition, for convenience of the following description, a part having an engagement convex part among both end parts is referred to as one end part 12A,
The portion having the engagement recess is referred to as the other end 12B.

The one end 12A is provided with a slide guide 14 which is partially looped in order to facilitate and suppress the insertion of the other end 12B. On the inside, as shown in FIG. 1 (b), a claw-shaped engaging projection 16A is formed.

On the other hand, on the outer surface of the other end 12B, an engaging recess 16B having a sawtooth cross section is formed. Thus, in the engagement type of this embodiment, both ends 12A and 12B are slid to engage both engagement portions 16A and 16B, and the band 1
0 is adjusted to the optimum length of the wearer and connected in an annular manner. In a state where the claw-shaped engaging projection 16A is engaged with the engaging recess 16B having a sawtooth cross section, the other end 12B is engaged. Is one end 1
Although it is possible to advance to 2A, it is not possible to retreat.

At the other end 12B, a hooking portion 20B is provided so as to project from a rear outer surface of the engaging concave portion 16B. Hanging part 20
It is sufficient that B has a size and shape that can be taken with a fingertip. Therefore, in addition to the illustrated semicircular shape,
The protrusions may be cylindrical or prismatic. FIG.
The through hole 22 may extend from the outer surface to the inner surface of the band 10 as shown in FIG. 2A, or may be a hinge 24 pivotally supported by a pin 23 as shown in FIG.

On the other hand, on the one end 12A side in the present embodiment, the retaining ring 15 of the slide guide 14 is connected to the one end 1A.
Since the slide guide 14 is formed slightly upright from the outer surface of 2A, the slide guide 14 is connected to the hook 20A of the one end 12A.
Can also be used. However, in the present invention, the slide guide 14 is not always essential. In the case of the band 10 which is not provided with the dual use of the locking portion 20A like the slide guide 14, the independent locking portion is also provided at the one end 12A. It is necessary to provide 20A.

Further, as shown in FIG.
Even when the slide guide 2A is provided with the slide guide 14, the protrusion 26 serving as the hook 20A may be provided on the one end 12A. The band 10 is made of vinyl chloride, polyethylene, other flexible synthetic resin, or hard rubber. At that time, the band 10 is attached to the arm, the leg,
It is preferable to preliminarily form a curved surface along the trunk or the like.

Since the band 10 of the present embodiment is constructed as described above, if a fingertip of one hand is hung on the retaining ring 15 as the engaging portion 20A and the engaging portion 20B and pulled together, the two engaging portions The other end portion 12B advances inside the slide guide 14 while the 16A and 16B rub against each other, so that the peripheral length of the band 10 can be adjusted to be short. In this state, even if the other end 12B is pulled in a direction to separate from the one end 12A,
Since both engaging portions 16A and 16B are engaged, there is no movement.

On the other hand, to release the engagement between the engaging portions 16A and 16B and to pull out the other end 12B from the one end 12A, the side of the slide guide 14 (particularly, the position of the snap ring 15) is used. To compress the retaining ring 15 from the outside (FIG. 1).
What is necessary is just to bend upward (in (a) and (b)). At this time, as shown in FIG.
As a result of the disengagement of B, the other end 12B retreats with respect to the one end 12A, and the band 10 naturally relaxes.

The band according to the present invention includes band 1
There is no particular restriction on the type of engagement at both ends of the zero. Therefore, in addition to the above-described embodiment, for a band in which the other end portion 12B of the band 10 is allowed to slide only in one direction with respect to the one end portion 12A in the locked state of the engagement portion, the pair of hooking portions 20A , 20B, the present invention can be applied.

[0020]

According to the band of the present invention, the size of the band can be adjusted with only one fingertip in the wearing state. Therefore, the band can be quickly and easily and reliably attached and detached. Further, since the structure of the band is extremely simple, the manufacturing cost is low and the weight of the band does not increase.
