ABSTRACT:
This invention is directed to a caster wheel foot brake assembly which may be used with casters on items such as shopping carts, strollers, moving carts, furniture and the like.
The brake assembly includes a foot pedal, pair of connector arms, brake arm, U-shaped braking foot and hinge spring which form an overcenter locking mechanism.
In order to engage the braking foot with the caster wheel, the user pushes down on the rear portion of the foot pad, thereby moving the braking foot overcenter in toggle fashion into a releasably locked braking position. In order to disengage the brake, the user may either push down on the front portion of the foot pad or pull back on the shopping cart or other item attached to the caster, thereby moving the braking foot back overcenter into a disengaged nonbraking position.
