  The present invention relates to a chest strap that attracts a pair of shoulder belts provided in a shoulder type storage bag at the chest to prevent slippage.

  Backing-type storage bags such as rucksacks, backpacks, daypacks, and the like have a structure in which the storage bag body is carried on the shoulders by passing a pair of shoulder belts from the arms and shoulders. When carrying a shoulder-type storage bag, the shoulder belt, which takes the weight of the storage bag itself, may slip off the shoulder. In order to prevent this, there is a product that is attached with a chest strap that attracts the left and right shoulder belts at the chest.

  In addition, a device has also been proposed in which the chest strap can be retrofitted to a backpack-type storage bag that is not equipped with a chest strap as a standard (see, for example, Patent Document 1). The chest strap described in Patent Document 1 has a ring-shaped strap end on the shoulder belt side, and the chest strap is attached by passing the shoulder belt in the ring-shaped strap. In addition, by applying anti-slip resin to the inside of the strap in contact with the shoulder belt, it has been devised that the mounting position of the chest strap is difficult to shift. Furthermore, the chest strap described in Patent Document 1 is provided with a buckle composed of a male and female element in the middle of the strap, and the shoulder type storage bag can be lowered simply by removing the buckle.

The connection end 22 a side of the second connection band portion 22 (the opposite side of the attachment end 22 b on which the clip 4 is provided) is attached to the male buckle 32.

  The female buckle 31 and the male buckle 32 constituting the buckle 3 can be connected and separated, and by connecting the female buckle 31 and the male buckle 32, the first connection band 21 and the second connection band 22 are connected, It functions as an integral connecting band 2. If, for example, a side release type is used as the buckle 3, the first connection band 21 and the second connection band 22 can be attached in a direction in which the male buckle 32 and the female buckle 31 are connected and separated. The connection end 21 a of the first connection band portion 21 is attached so as not to be detached from the band attachment portion of the female buckle 31. On the other hand, the band attachment portion of the male buckle 32 has an adjuster structure capable of unwinding and returning the band without fixing the band, and adjusting the length from the attachment end 22b of the second connection band 22 to the male buckle 32 The length of the entire connecting band 2 can be adjusted.

  The connection / separation structure of the buckle 3 is not particularly limited, but an example is shown. The male buckle 32 is provided with a first engagement claw piece 32 a and a second engagement claw piece 32 b which can be elastically deformed, and the engagement receiving portion formed in the female buckle 31 is a first and second engagement claw piece 32 a. , 32b are engaged, the female buckle 31 and the male buckle 32 are connected. The female buckle 31 is provided with a first operation recess 31a and a second operation recess 31b, and when the female buckle 31 and the male buckle 32 are connected, a part of the first engagement claw piece 32a is formed in the first operation recess 31a. However, a part of the second engagement claw piece 32b is in a state of being protruded to the second operation recess 31b. And if 1st, 2nd operation recessed part 31a, 31b is pushed with fingers etc. and 1st, 2nd engagement claw piece 32a, 32b is pushed in, 1st, 2nd engagement claw piece 32a, 32b will be elastically deformed. And the female buckle 31 and the male buckle 32 can be separated.

  The clips 4 and 4 respectively provided on both ends of the connection band 2 (the attachment end 21b of the first connection band 21 and the attachment end 22b of the second connection band 22) are attached to the first shoulder belt 102a and the second shoulder belt 102b. Or remove it. The clip 4 has an open state in which the first pressing body 41 and the second pressing body 42 are separated and the first and second shoulder belts 102a and 102b can be inserted so that the first and second pressing bodies 41 and 42 It is converted to a closed state in which the first and second shoulder belts 102a and 102b can be held close to each other.

  An example of the clip 4 is shown in FIG. In the closed state, in the clip 4, the pressure contact portion 41a of the first pressing body 41 and the pressure contact portion 42a of the second pressing body 42 face each other in a close manner, and there is no space where the first and second shoulder belts 102a and 102b can be inserted (see FIG. 2 (A)). In the closed state, the open / close operation unit 43 which also serves as the band attachment portion is located in the tension direction (the left and right direction in FIG. 2A) of the connection band 2.

  When the open / close operation unit 43 of the clip 4 is rotated (for example, rotated approximately 90 degrees in the α direction in FIG. 2B), an appropriate link mechanism acts, and the pressure contact portion 41 a of the first pressing body 41 is operated. As a result, the pressure contact portion 42a of the second pressing body 42 moves in the direction ([beta] direction in FIG. 2B) in which the pressure contact portion 42a is separated. And, between the pressure contact portion 41a of the first pressing body 41 and the pressure contact portion 42a of the second pressing body 42, a sandwiching empty portion 44 is formed in which the first and second shoulder belts 102a and 102b can be inserted to the back.
