发明名称 Strap lifter for use between two persons
摘要 A strap lifter for use with a harness is shown and described. The harness may have two shoulder straps that support a central, front buckle for use at about the lower, central belly of a user. A generally horizontal buckle strap has a fixed, rigid lower loop beneath a movable, flexible upper loop secured to the front of the buckle strap. The lower and upper loops are generally parallel, and close, to each other. Typically, the distance between the two loops is slightly more than the thickness of a lifter strap which is threaded between the two loops. Preferably, a set of two harnesses is used by two persons standing face-to-face with a single lifter strap between them threaded through both of the buckles.

主权项 1. A strap lifter comprising: a harness with a generally horizontal strap; a generally horizontal, moveable, flexible upper loop secured to said horizontal strap at both ends of said upper loop, the ends of said upper loop being made of a flexible material; and a generally horizontal, fixed, rigid lower loop also secured at both ends to said horizontal strap, said lower loop being generally parallel to, but beneath, said upper loop; wherein flexing of said ends of the upper loop moves the upper loop toward the rigid lower loop from a raised position to a lowered position; and a central lifter strap threaded around the upper loop and through the lower loop, wherein the upper loop in said raised position is spaced-apart from the lower loop slightly more than the thickness of the central lifter strap, and wherein the upper loop in said lowered position pinches the central lifter strap against the lower loop.
