Abstract:
A brake actuation assembly for mounting on a handle of a rollator, comprising:(a) a base having a pair of spaced wall portions defining a accommodation space therebetween, said base having a positioning protrusion extending into an upper portion of said accommodation space and a stopper wall extending into a lower portion of said accommodation space;(b) a longitudinally extended rod disposed in said accommodation space between said spaced wall portions of said base, said rod having a first end portion pivotally coupled to said base for displacement within said accommodation space and a second end portion coupled to a brake cable, said rod having formed therethrough a pin hole spaced longitudinally from said first and second end portions; and,(c) a grip coupled to said rod and displaceable relative to said base, said grip having a trough formed between a pair of extending nose portions in an end of said grip for receiving said rod therein, said rod being pivotally coupled between said nose portions through said pin hole, said grip having a protrusion formed at an upper portion of said end of said grip and spaced from said nose portions for interfacing with said first end portion of said rod to form a first fulcrum for displacement of said grip in a first direction toward the rollator's handle to actuate a brake, said grip having a stopper tongue formed at a lower portion of said end of said grip and spaced from said nose portions for interfacing with said stopper wall to form a second fulcrum for displacement of said grip in a second direction away from the rollator's handle to actuate the brake, said pair of nose portions engaging said positioning protrusion responsive to said grip being displaced a predetermined distance in said second direction to maintain an actuated condition of the brake, said nose portions being disengaged from said positioning protrusion to release the brake responsive to said grip being displaced in said first direction.
