Abstract

This invention presents strap apparatus that is attached to a carrying bag such as a briefcase, computer bag, or golf club bag. In the first embodiment, the strap apparatus is constructed from a single strap that is configured as a closed loop. The closed loop is constrained to the sides of the bag near the top by two constraining means; the closed loop being divided into two strap segments of approximately equal lengths. Depending on how the straps are shouldered, the bag may be worn in a single-strap configuration, a backpack configuration, or a dual-strap configuration. Transitioning from one configuration to the other is easily done by the wearer without having to remove the apparatus from the bag. Furthermore when in the single-strap configuration, the straps stay together and appear to the casual observer as a single-strap as found on an ordinary bag. The appearance of the bag when in the single-strap configuration will not reveal its multimode capability.

A multimode shoulder strap apparatus for a carrying bag, comprising:

(a) a carrying bag 3 comprising a right side 3R, a left side 3L, a front 3F, a back 3B, a bottom 3BT, and a top 3T,
(b) a first strap segment 9O and a second strap segment 9I, the two strap segments having approximately equal lengths,
(c) first constraining means 5R for constraining one end of said first strap segment to said bag disposed approximately at said right side and a second constraining means 5L for constraining the other end of said first strap segment to said bag disposed approximately at said left side;
said first constraining means also constraining one end of said second strap segment to said bag disposed approximately at said right side and said second constraining means also constraining the other end of said second strap segment to said bag disposed approximately at said left side,
(d) said bag having a single-strap configuration activated by a wearer by enacting the following sequentially:
grabbing the two strap segments with one hand so said bag hangs in a predominately upright position whereas said bottom of said bag is parallel to the floor so that the two strap segments above said bag appear similar to a single strap;
putting the two strap segments over one shoulder so said bag is worn as a single-strap shoulder bag, and
(e) said bag having a backpack configuration activated by enacting the following sequentially:
grabbing the two strap segments with the right hand so said bag hangs in a predominately upright position;
grabbing said first strap segment with left hand with palms down;
grabbing said second strap segment with right hand with palms down;
lifting said bag by the two strap segments so said bag hangs in a predominately upright position with said bottom of said bag approximately parallel to the floor;
putting the strap segments one on each shoulder so said bag is on the users back and said bag is worn as a backpack.
