Description

  The present invention relates to a belt backpack capable of carrying a handbag, a shoulder bag or the like with a shoulder belt.

  As this type of shoulder belt, those disclosed in the following patent documents are known. Among these, in Patent Document 1, the belt is not hung on both sides of the bag, and the upper and lower sides of the bag are only wrapped with slanted belts, so the belt is easy to loosen and loses its balance when the bag's center of gravity shifts. There is a problem that the bag falls out of the carrying belt.

  In Patent Document 3, the handle of the bag is hung with a hook. However, there are hard handles for men, and when the handle is hung with a hook, the hanging position moves and loses balance. On the contrary, there is a problem that the bag tilts. Furthermore, although the lower part of the bag is fixed with an adhesive material, the adhesive material may come off when the bag is deformed by leaning on or being pushed. Moreover, there is a possibility that the cloth of the bag may be damaged by the adhesive material, and the adhesive material itself may lose its adhesiveness as the use frequency increases.

  Further, even in the methods of Patent Documents 2 and 4 in which a belt is wound around the base of a handle and the center of gravity position of the bag is biased, there is a problem that the shoulder bag is inclined. In particular, in the method of Patent Document 2, since the bag and the belt are connected only by a holder that holds the handle portion of the bag, even if the bag is carried on the back, the bag always dances around the holder. There is a problem that the bag is not stable.

  Further, in the method of Patent Document 4, since the length of the belt cannot be adjusted, there is a problem that when the bag is inflated, it cannot be carried on the back. Furthermore, if the bag is pushed up and lifted to loosen the belt, the belt at the bottom may come off.
