Lift-assist device
View Patent ↗Stabilizing lift-assist devices include a framework having a graspable handle and at least two V-shaped framework members that provide kinematic constraints for a weight bar received therein. Such lift-assist devices can be used for stabilizing a weight bar during exercise to reduce the possibility of injury from slippage or body positioning that leads to hyperextension of various physiologies.
1. A barbell-stabilizing lift-assist device, comprising:
a substantially U-shaped handle portion having left and right sides, and a cylindrical gripping member disposed between said left and right sides configured to be gripped by a hand;
an arcuate, elongate armature having a proximal end portion integral with said substantially U-shaped handle portion and a distal end portion comprising a semicircle-shaped recess;
a semicircle-shaped clamping member pivotally coupled to said distal end portion of said armature that is shiftable between open and closed configurations; and
a lever-actuated locking member comprising a latch member disposed on said semicircle-shaped clamping member that is configured to engage one of a plurality of latch recesses on a terminal end portion of said elongate armature;
wherein said clamping member and said semicircle-shaped recess of said armature cooperatively form a circular aperture configured to frictionally engage a barbell portion when said clamping member is in said closed configuration such that said barbell-stabilizing lift-assist device is reversibly locked in position on said barbell portion;
wherein a middle portion of said armature is configured to rest upon a user's shoulder, providing a barbell-stabilizing configuration wherein said handle portion is forward of said user's shoulder and said distal end portion is rearward of said user's shoulder; and
wherein said armature between said handle portion and said distal end portion has a width that is less than a width of said handle portion.
