Description

  The present invention relates to an expansion / contraction adjustment technique that makes it possible to easily adjust the length of a strap attached to a mobile phone or a camera.

  Various straps have been developed and sold so far. Some of them allow the strap length to be adjusted. Patent document 1 is an example.

Utility Model Registration No. 3075753

In general, in order to adjust the length of the strap, there are many types in which the strap is once removed from the body, adjusted to a desired length, and then attached to the body again. However, this type has the following drawbacks.
(1) The above work is very troublesome, and it is difficult to slightly change the length of the strap while walking along the road.
(2) Also, since the length is adjusted once because it is removed from the body, the adjusted length is not always the desired length. there were.

  Accordingly, an object of the present invention is to provide a novel strap expansion / contraction adjustment technique that allows the length of the strap to be easily adjusted even when the strap is worn on the body. However, this strap expansion / contraction adjustment technology is not limited to a strap (for example, a neck strap) to be worn on the body, but is also used for other straps such as a hand strap for holding in a hand.

  In order to solve the above-described problem, the first invention is an expansion / contraction adjustment mechanism that can adjust the length of the strap, and the expansion / contraction adjustment mechanism is configured such that a part of the strap body is overlapped with an upper piece and a lower piece. The upper and lower parts of the expansion and contraction adjustment part extend to one side, the lower piece extends to the other, and the upper piece is attached to the end of the upper piece and the upper piece is attached to the end of the lower piece. It is characterized by having a band to pass through.

The second invention is provided with an ear part that can be grasped with a finger at the end of the upper piece in order to slide the upper piece, and an ear part that can be grasped with a finger on the belt of the lower piece in order to slide the lower piece. It is a feature.
The third invention is characterized in that an anti-slip member is attached to a sliding contact surface where the upper piece and the lower piece are in contact with each other.
According to a fourth aspect of the present invention, a stopper member is provided on the upper piece and / or the lower piece in order to control the sliding range of the upper piece and / or the lower piece.

The present invention has the following effects.
(1) By pulling the end portion of the upper piece and the end portion of the lower piece outward, the stretch adjustment portion where the upper piece and the lower piece are overlapped becomes longer, and the length of the entire strap can be shortened accordingly. In addition, by pulling the strap body outward, the stretch adjustment portion where the upper piece and the lower piece are overlapped is shortened, and the length of the entire strap can be increased accordingly.
(2) As shown in (1) above, the length of the strap can be easily changed by pulling the ends of the upper and lower pieces outward or by pulling the strap body outward. Even if you wear it on your body, you can adjust the length of the strap while wearing it.
(3) By providing the end portion of the upper piece and the band of the lower piece with the ear portion, it becomes easy to pull the end portion of the upper piece and the end portion of the lower piece outward.
(4) By attaching the anti-slip member to the sliding contact surface where the upper piece and the lower piece are in contact, the upper piece and the lower piece do not slide easily, and the length of the strap once adjusted can be reliably maintained.
(5) By providing a stopper member on the upper piece and / or the lower piece, the sliding range of the upper piece and / or the lower piece is controlled, and the expansion and contraction of the strap can be controlled within a certain range.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing an expansion / contraction adjustment mechanism of the present invention.
The expansion / contraction adjustment mechanism of the strap 10 is configured such that a part of the strap body 11 is an expansion / contraction adjustment unit 40 in which the upper piece 20 and the lower piece 30 are overlapped. The upper piece 20 of the expansion / contraction adjusting portion 40 extends leftward in the drawing, and the lower piece 30 extends rightward opposite to the upper piece 20. The end piece 21 of the upper piece 20 is provided with a band 25 through which the lower piece 30 is passed, and the end piece 31 of the lower piece 30 is provided with a band 35 through which the upper piece 20 is passed.

  Further, an ear portion 27 is formed on the end portion 21 of the upper piece 20, and an ear portion 37 is formed on the band body 35 of the lower piece 30. The ears 27 and 37 have a substantially triangular shape with a thin tip so as to be easily grasped by a finger. However, the shape of the ear portion is not limited to this.

  In addition, an anti-slip member 50 is attached to either one of the sliding contact surfaces 22 and 32 where the upper piece 20 and the lower piece 30 are in contact. For the non-slip member 50, for example, operon rubber or polyester material is used.

  In addition, stopper members 12 and 12 are provided on the upper piece 20 and the lower piece 30 in order to control the sliding range of the upper piece 20 and the lower piece 30. The stopper members 12 and 12 are outside the end portion 21 of the upper piece 20 and the end portion 31 of the lower piece 30 and are attached so as to be wound around the strap main bodies 11 and 11. The stopper member is not limited to this, and any stopper member that can stop the sliding of the upper piece 20 and the lower piece 30 may be used.

  FIG. 2 is a front view of the expansion / contraction adjustment mechanism of the present invention having the above-described configuration as viewed from the front, FIG. 3 is a plan view from the same plane, and FIG. 4 is a bottom view from the bottom.

5 and 6 are explanatory front views showing a usage state of the expansion / contraction adjusting mechanism of the present invention.
As shown in FIG. 5, by pulling the strap bodies 11, 11 outward, the stretch adjustment part 40 in which the upper piece 20 and the lower piece 30 are overlapped is shortened, and the entire length of the strap 10 can be lengthened accordingly. It is.

  On the other hand, as shown in FIG. 6, by stretching the end portion 21 of the upper piece 20 and the end portion 31 of the lower piece 30 to the outside, the stretch adjustment part 40 in which the upper piece 20 and the lower piece 30 are overlapped becomes longer. Accordingly, the entire length of the strap 10 can be shortened. At this time, since the upper piece 20 and the lower piece 30 are provided with the ear portions 27 and 37, respectively, it becomes easy to pull outward. Further, when the upper piece 20 and the lower piece 30 slide over a certain distance, the band members 25 and 35 come into contact with the stopper members 12 and 12, and the sliding range is controlled.

  In any case shown in FIGS. 5 and 6, the anti-slip member 50 is attached to one of the sliding contact surfaces 22 and 32 where the upper piece 20 and the lower piece 30 are in contact. Therefore, the upper piece 20 and the lower piece 30 do not slide easily, and the length of the strap 10 once adjusted is reliably maintained.

  FIG. 7 is an explanatory diagram showing a use state in which the strap 10 having the above-described expansion / contraction adjusting mechanism is used as a neck strap. Since the expansion / contraction adjustment part 40 of the strap 10 is located on the back side of the neck, it can be kept worn by turning the hand back and pulling the ears 27 and 37 outward or by pulling the strap bodies 11 and 11 outward. In this state, the length of the strap 10 can be adjusted very easily.

  The expansion / contraction adjustment technology of the strap of the present invention is not limited to a strap (for example, a neck strap) to be worn on the body, but can also be used for various types of straps such as a hand strap for holding in a hand.
