Description

  The present invention relates to a backpack type bag (hereinafter collectively referred to as “rucksack”) called various names such as a rucksack, a backpack, a daypack, a knapsack, and the like. In particular, the present invention relates to a rucksack having a mechanism for stabilizing the position of a shoulder strap.

  The shoulder strap of the rucksack may come down gradually due to improper length adjustment, weight of luggage, shoulder of the wearer. If you continue to do so, your posture may worsen, which may cause back pain.

  In order to stabilize the position of the shoulder strap, it is a common practice to connect the left and right two straps horizontally with a chest belt. In addition, in Japanese Patent Laid-Open No. 2000-296019, the shoulder strap is fixed with a connector so as to be in a cross shape.

JP2000-296019

  In many cases, the length of the horizontal chest belt is adjustable, but the position is only stabilized in the horizontal direction. However, the shoulder strap is curved and runs from the shoulder of the wearer toward the flank, and it is often insufficient to stabilize the position only in the horizontal direction.

  The above Japanese Patent Laid-Open No. 2000-296019 relates to the improvement of the shoulder strap, not the chest belt. Also, the diagonal angle cannot be adjusted.

  An object of the present invention is to provide a rucksack capable of stabilizing the position of a shoulder strap in an oblique direction. It is another object of the present invention to provide a rucksack whose angle in the oblique direction can be adjusted.

  The present invention for solving the above-mentioned problems is a chest belt 4, 4A, comprising a luggage storage portion 2, left and right shoulder straps 3, 3A, 3B, left and right belt pieces 5, 6; 5A, 6A; 5B, 6B. 4B and the right and left belt pieces 5, 6; 5A, 6A; in the rucksack 1 having connecting members 7, 7A, 7B for detachably connecting the left and right belt pieces, It has a means fixed so that it may form a triangle with respect to (Claim 1). Here, the “triangle” has two points where the shoulder strap 3 side is spaced, and one point where the connecting tool 7 side of the left and right belt pieces 5 and 6 is the apex. It means to become. The actual contour may be other than a triangle (for example, a circle, an indefinite shape, etc.).

  As means for fixing the left and right belt pieces so as to form a triangle with respect to the left and right shoulder straps, for example, the following means can be employed.

(A) The means for fixing the left and right belt pieces so as to form a triangle with respect to the left and right shoulder straps is such that the left and right belt pieces 5 and 6 have two belt pieces 51 and 52; 61 and 62, respectively. The shoulder strap 3 side of each belt piece 51, 52; 61, 62 is sewn to the shoulder strap with a thread 9 (claim 2). Here, the “two belt pieces” may not be two separated but may be one folded.

(B) The means for fixing the left and right belt pieces so as to form a triangle with respect to the left and right shoulder straps has two belt pieces 51A, 52A and 61A, 62A, respectively. Each of the belt pieces 51A, 52A and / or the shoulder strap 3A has a plurality of fixing elements 8, and the shoulder strap 3A side of each of the belt pieces 51A, 52A can be fixed to the selected fixing element 8 ( Claim 3). Here, the “two belt pieces” may not be two separated but may be one folded.

(C) The means for fixing the left and right belt pieces so as to form a triangle with respect to the left and right shoulder straps, each of the left and right belt pieces has one triangular belt piece 4B, and the triangular belt piece 4B and / or the shoulder strap 3B has a plurality of fixing elements 8B, and the shoulder strap side of each triangular belt piece 4B can be fixed to the selected fixing element 8B (Claim 4).

  According to the present invention, since the left and right belt pieces have means fixed to form a triangle with respect to the left and right shoulder straps, the shoulder straps can be fixed in a slanting direction. As a result, the rucksack does not wobble due to the fit of the wearer's back. As a result, the posture of the wearer is improved and the cause of low back pain can be reduced.

  Claims 2 to 4 are specific examples of means for fixing the left and right belt pieces so as to form a triangle with respect to the left and right shoulder straps. In addition, various combinations can be made in terms of whether the left and right belt pieces are one or two or more, whether fixing is by thread sewing, what fixing elements are used, and the like.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 is a rear view of a rucksack according to Embodiment 1 of the present invention. It is an enlarged view of the chest belt part in FIG. It is an enlarged view of the chest belt part of the rucksack which concerns on Example 2 of this invention.
