Abstract
A brake and wheel assembly featuring a brake band and an actuator capable of being moved between first and second braking positions. The brake band is carried by a support and is suspended tangentially across the surface of a wheel. The wheel is rotatably supported on an axle. The actuator is supported in the assembly, and applies a tangential force on the brake band so that first and second braking surfaces on the brake band frictionally engage the actuator in the respective first and second braking positions.
Claims18
A brake and a wheel assembly comprising;
- a support,
- an axle supported by said support,
- a wheel rotatably supported on said axle,
- a brake band supported by said support tangentially across the wheel, and
- an actuator movably supported in said assembly for movement between first and second brake-applying positions to engage said brake band with the wheel in either of said first or second brake-applying positions.
2 more elements
A cart for transporting an article comprising;
- a frame for receiving and supporting the article,
- a plurality of spaced brake and wheel assemblies carried by said frame, each of said brake and wheel assemblies including
- a housing carried by said frame and having opposed sidewalls defining slots,
- an axle supporting said frame and extending outwardly away at an angle therefrom,
- a wheel rotatably supported on said axle and received within said housing,
- a brake band having opposed free ends received within said slots for suspending said brake band tangentially across said wheel and spaced detents extending from said brake band away from said wheel, and
- an actuator having a proximal end carried by said frame for pivotal movement relative to said axle, a distal end extending radially from said proximal end, a pedal connected to said distal end, and a shoulder connected to said actuator between said proximal end and said pedal, said pedal for receiving a downwardly-directed force to initiate pivotal movement of said actuator, whereby said shoulder moves through an arc relative to said wheel and frictionally engages each of said detents in a selected one of two brake-applying positions.
