  • 1. Technical Field
  • The present invention is related to side-carrying bags and more particularly, to a dual shoulder strap side-carrying bag, which provides a double-shoulder side-carrying function subject to the arrangement of a shoulder stand.
  • 2. Description of the Prior Art
  • Regular commercial shoulder bags include two types, namely, the back-carrying type and the side-carrying type. A back-carrying type shoulder bag, for example, backpack, has two shoulder straps for enabling the weight of the shoulder bag to be evenly distributed through the user's two shoulders, facilitating carrying heavy items or long-time carrying application.
  • When using a back-carrying bag, the user will carry the back-carrying bag on the back. When going to pick up a storage item from the back-carrying bag, the user may need to remove the back-carrying bag from the shoulders. In other words, the user cannot easily pick up storage items from the back-carrying bag that is carried on the back.
  • A side-carrying bag has a single shoulder strap connected to the bag body thereof. By means of the shoulder strap, a user can carry the side-carrying bag on one shoulder. When carrying the side-carrying bag on one shoulder, the user can adjust the position of the bag body to the user's front side, one lateral side or back side conveniently when desired. In other words, the user can pick up storage items from the side-carrying bag easily without removing the side-carrying bag from the shoulder.
  • However, when using a side-carrying bag, the shoulder bears all the weight of the side-carrying bag. Therefore, a side-carrying bag is not suitable for carrying heavy items or for a long-time application.
