This invention discloses strap apparatus that is attached to a carrying bag such as a purse, briefcase or message bag. The strap apparatus is constructed from a single flat strap configured as a closed loop. The loop is constrained to each side of the bag at the bottom; the outside first side and inside second side of the strap are also constrained to lie against the sides of the bag near the top; and the inside first side and outside second side are releasably constrained at the sides of the bag at the top. When fully constrained, the bag appears to a casual observer as having a standard single strap. However, when the constraints are released, the two strap segments may be separated and the bag can be put over the shoulder as a backpack. Two other modes, a dual strap and a long strap, are also disclosed. |
