ABSTRACT:
The novel weight-balancing device of the present invention is adapted for use in the improved backpack of the present invention. The device comprises a set of two elongated tubes, disposed in telescoping relation to each other with a spring-loaded push button carried by the inner tube adjustably releasably locking the tubes together so that they can have various desired combined lengths. One of the tubes has a slip resistant backpack shoulder strap connector attached at its front end and the other of the tubes has a backpack rear frame connector pivotally secured to its rear end.
The improved backpack utilizes a pair of the described novel devices, connected to opposite sides of the backpack rear frame and projecting forwardly to engage the two backpack shoulder straps. Thus, the two devices are disposed on opposite sides of the backpacker. Their purpose is to shift the center of gravity and balance of the backpack from aft of the vertical midline of the backpacker when standing erect with the backpack in place, that is, from a very uncomfortable and clumsy position to a more forward comfortable position adjacent that vertical midline of the backpacker, without the backpacker having to continually tug at the backpack shoulder straps and hunch over to achieve the weight shift. The device is simple, inexpensive, light in weight, durable, easy to install and remove, and is very efficient.
