Description

[Detailed Description of the Invention] The present invention relates to a fastener having a mechanism for adjusting the length of a backpack strap or the like.

The object of the present invention is to provide this type of fastener at low cost by extremely simply constructing it using synthetic resin or the like and reducing manufacturing costs.

To explain the embodiment of the present invention, a rectangular frame body 2 having a through hole 1 in the center is provided, a band attachment ring 3 is formed at one end of the frame body 2, and both sides 4, 4 of the frame body 2 are provided. Horizontal hole 5,5
A locking rod 6 in which the locking rod 6 slides between the holes 5 and 5.
The protruding shafts 6A, 6A of the frame body 2 are inserted thereinto, and the inside of the front side portion 2A of the frame body 2 is formed as a right-angled wall or an acute-angled wall 2B to form an inner end frontage portion 2C.

In addition, the reference numeral 7 in the figure is a vertical hole provided on one side of the side portion 4 in order to insert the locking rod 6 into the horizontal hole 5.

To explain how to use the present invention, the lower belt C of a backpack belt such as a backpack is attached to the belt attachment ring 3 connected to the frame body 2.

One end of the upper band is inserted into the through hole 1 from below the front side 2A of the frame 2, and is inserted below the through hole 1 from above the locking rod 6 to form two layers, and in this state, the upper band When the lever is pulled back upwards, the locking piece 6 moves upward, and a two-layer upper band is formed between the right angle wall or acute angle wall 2B of the inner end opening 2C of the frame body 2 and the locking rod 6. is pinched.

Therefore, the upper band is reliably prevented from loosening.

In addition, to adjust the length of the upper band, hold the frame 2, turn over the sleeve DA in the double layered upper band, and pull it a little, the locking rod 6 will move downward and the tightened state will be released. It will be destroyed.

Therefore, lightly pull the facial expression DB upward to make the facial expression DB the desired length, and place the facial expression DA under the facial expression DB again and position it at the inner end opening 2C of the frame body 2 to clamp the upper obi. .

In addition, to shorten the upper obi, turn over the sleeve DA, hold the frame 2 and pull it downward to adjust the length of the sleeve DB to the desired length, overlap the sleeve DB with the sleeve DA, and attach the frame. 2 at the inner end opening 2C to clamp the upper band.

In the present invention, the locking rod 6 is set to a length that allows the upper band to be pulled upward lightly at the right angle wall or the acute angle wall 2B of the inner end frontage 2C inside the front side 2A of the frame 2, so that the upper band is securely tightened. It is clamped and tightened.

In addition, the fastener of the present invention has an extremely simple structure consisting of three parts: a synthetic resin frame 2, a part connecting the band attachment ring 3, and a locking rod 6, and is easy to assemble, so the manufacturing cost is low. It has the characteristic that it can be provided at a low cost with reduced costs.

Therefore, adjusting the length of the upper belt to be fixed to the frame body 2 is a relatively simple operation, so it can be used to adjust the diameter of the torso of not only backpacks but also clothing, exercise clothes, pants, etc. It can be used as a fastener for the hem of pants, the cuff of clothing, etc.
