Description

  The present invention relates to backpacks such as rucksacks, knapsacks and school bags.

  Back bags such as rucksacks are characterized by the fact that the load is less likely to be biased on one of the shoulders because the belt is supported by the belt on both shoulders. Therefore, it is easy to maintain the balance of posture, and it can be used freely with both hands, and it is widely used because it is kind to the body and functional.

  In fact, after changing from a shoulder bag (shoulder bag) to a rucksack, there is an example where the posture is improved and the back pain and stiff shoulders are improved.

  However, backpacks and other backpacks may adversely affect the posture depending on the type of backpack. For example, if the shoulder belt is lengthened and the storage area is placed around the buttocks, the storage area containing luggage will easily come back from the body, so in order to stabilize this, it will be in the posture of the cat back There was a case that

  Here, Patent Document 1 below describes a belted rucksack that corrects the back of a cat or the like.

True No. 3214444

  The present invention has been made in consideration of the above-described matters, and provides a backpack that can easily maintain a correct posture.

  In order to solve the above problems, the bag according to the present invention includes a storage unit main body for storing articles, two shoulder belts stretched from the upper portion to the lower portion of the storage unit main body, and mounting of the storage unit main body. Provided with a protuberance which is provided on the outer side of the wearer side and which is protuberantly protrusively in the lateral and lateral directions on the wearer side, and a waist belt extending from the lower left and right of the storage portion main body; While being located in the lower part of an outer side, it was set as the structure formed of the elastic member which has elasticity. Here, "back and shoulder bag" includes not only rucksacks but also knapsacks and school bags.

In this bag, by tightening the waist belt, the laterally raised ridges come in pressure contact with the waist area of the wearer. That is, since the back is pushed from behind, the spine extends and it is easy to maintain the correct posture. Since the raised portion is formed by an elastic member having elasticity, it easily fits around the waist of the wearer. In addition, since the protuberances are laterally long, a gap is easily generated between the protuberances and the back, which makes it difficult to cause stuffiness.
The elastic member is directly attached to the wearer side outer surface of the storage unit main body and covered with a cover as required, or inserted into a storage pocket provided on the wearer side outer surface of the storage unit main body, or the elastic member It is possible to put it in the body and attach it to the wearer-side outer surface of the storage unit body together with the bag body. The ridges can be formed by such means.

  Here, it is preferable to set the protrusion size of the raised portion to 3 to 10 cm, from the viewpoint of maintaining the correct posture and the viewpoint of wearing feeling, because both are well balanced. The ridge size of the ridges is more preferably 4 to 7 cm.

  Further, an inner pocket is attached to an inner side wall on the wearer side inside the storage unit main body, and an inner pocket for storing an article such as a book inside, and a restraint means for restraining an article stored in the inner pocket from the outside of the inner pocket , And can be configured.

  This backpack can store articles such as books in the inner pocket attached to the inner wall of the wearer, and the articles such as books are restrained at a position close to the wearer. It makes it easy to feel the weight of the bag light.

  Further, the chest belt may be provided to connect two shoulder belts at an intermediate position, and the chest belt may be configured to have a length adjustment mechanism.

  When the chest belt is tightened while the waist belt is tightened and the raised part is in pressure contact with the waist area of the wearer, the bag will rise slightly and adhere from the shoulder to the back of the wearer. This makes it easier to maintain the correct posture, and makes it easier to feel the weight of the bag (which often contains stored items).

  Here, the shape of the elastic member can be such that the cross section perpendicular to the left and right direction is substantially semicircular or substantially wedge shaped, or the cross section perpendicular to the left and right direction is substantially triangular. As a material of the elastic member, urethane foam is preferable.

  By forming the elastic member in such a shape, it becomes easier to fit around the waist of the wearer.

  Also, the elastic member can be configured to be removable. For example, a storage pocket in which the elastic member can be put in and out can be provided in the lower part of the wearer-side outer side surface of the storage portion main body, and the elastic member can be inserted here.

  This bag is easy to replace the elastic member. In addition, it is possible to select the hardness, shape, and the like of the elastic member to be used in accordance with the wearer's body shape and the like.

  In addition, the present invention can be suitably applied to a backpack for schooling even in a bag. Furthermore, the present invention can be suitably applied to a school bag in a bag.

  According to the present invention, it is possible to provide a backpack that is easy to maintain a correct posture.
