Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a band adjustment tool used to adjust the length of a band of a hand-hanging case, shoulder-type equipment, etc.

(Prior Art and Problems) In a bunt that is used in a shoulder format by attaching both ends of the bunt to a shoulder case, a video camera, etc., a band adjustment tool is used because the length needs to be adjusted.

The end of the band is folded back and inserted into the ring fitting, and the very end is fixed to the adjustment tool. However, in the conventional band adjustment tool, as shown in FIG. The band 36 has an intermediate part 31 at the front and rear, and has band insertion parts 32, 33 and front and rear cross bars 34, 35. Since it is only applied twice to the side, when adjusting the band, if one side 36' is pulled out, there is a risk that the very end 36a may come off. If you operate it while it is suspended, there is a risk of it falling and being damaged.

In addition, the band is double layered, and the front, front, and middle horizontal bars 31, 34, and 35 all have a constant thickness and the same height, so they have a large degree of bending and are difficult to slip, making it even more difficult to operate. Therefore, there is a problem in that if you pull it forcibly, there is a high probability that you will accidentally cause an accident like the one described above.

(Technical Issue) Therefore, in the present invention, the extreme end of the band is fixed to the adjuster body so that it does not move, and the adjuster body can be easily slid up and down by hand during adjustment operations. This is a technical issue.

(Means for solving the problems) In order to solve the above technical problems, the present invention
It is a band adjustment tool that is inserted into the middle part of the band and fastens the folded end part, and the adjustment tool body has a rectangular frame shape. A rod is integrally provided, and a locking rod is provided that protrudes from the back side of the horizontal rod in the middle to lock the end of the band in a way that prevents it from coming off. The opening/closing lid has a vertically divided portion sandwiching the locking rod from the left and right sides, and a protrusion for fitting into the main body is provided on the side surface of the free end.

(Function) The band 1 exits from the front opening 3 of the adjuster main body 2 through the lower side of the front horizontal bar 4 to the upper side of the intermediate horizontal lever 5, and is pulled out from the lower side of the rear horizontal lever 6 to the rear opening 7. The end portion 1a is inserted into the suspension ring 11 of the suspended object 10 and folded in half, and the end portion 1a is applied from the rear opening 7 to the lower side of the horizontal rod 5 in the middle portion. It is fitted into the locking rod 8 to prevent it from coming off. After that, when the opening/closing lid 9 is closed, the state shown in FIG. 4 is obtained.

To adjust the length of band 1, do the following: First, to lengthen the band 1, grasp both sides of the adjuster main body 2 and use the other hand to pull the band 1b and pull it out from the front opening 3. If you want to shorten it, just grab the upper band 1c on the opposite side and pull it out from the rear opening 7.

When opening/closing the opening/closing lid 9, when the tabs 9a on both sides of the opening/closing lid 9 are pinched with fingers and pressed inward, the vertically divided portions 12 are compressed against the retained elasticity, so that the protrusions 9b on both sides correspond to the main body. In order to remove it from the side recess 2a, it can be opened or closed using the pivot portion 9c at the rear end as a fulcrum as shown by the chain line in FIG.

(effect) The present invention has the following unique effects.

The very end of the band is attached to a locking rod that protrudes below the intermediate horizontal rod of the adjuster body, so there is no worry that it will come off even if the rear side of the band is pulled. Even when heavy equipment such as a camera is carried directly on the shoulder, accidents such as dropping it due to incorrect operation can be avoided.

The length of the band can be adjusted easily and quickly by pulling the front or back of the band and moving the adjuster body back and forth by hand with a light touch.

The band insertion part into the adjuster main body is attached with a gently curved surface with the degree of bending suppressed, so that the band does not become difficult to operate due to bending, and adjustment can always be carried out smoothly.

The opening/closing lid can be opened and closed with a single touch, making it possible to easily and quickly attach and replace the band.

The structure is simple and can be manufactured at low cost.

(Embodiment) The adjuster main body 2 is integrally formed as a molded product using hard plastic, for example, DURACON resin.
Front, rear, and intermediate transverse rods 4, 5, and 6 are formed on the upper part of the main body 2.

The intermediate horizontal rod 5 is formed at a lower level than the front and rear horizontal rods 4 and 6 so that the upper surface is stepped. This allows band 1
The degree of bending can be reduced.

A locking hole 1 for the locking rod 8 is provided in the band end portion 1a.
d is provided, the locking rod 8 is inserted therein, and the opening/closing lid 9 is closed, so that it will never come off.

The opening/closing lid 9 is molded from the same elastic resin as the main body, and has a vertically divided portion 12 at the center of the front part.

The knob piece 9a is provided integrally with the opening/closing lid 9 so as to protrude laterally as shown in FIG. The pivot portion 9c of the opening/closing lid 9 can be pivoted by providing projections on both sides of the rear end of the opening/closing lid 9 and fitting them into recesses formed inside the main body.
