Abstract
A grocery cart braking system is described having a brake release bail bar assembly, a clutch disk assembly, a replaceable sacrificial brake shoe, and a biased brake rod assembly. The clutch disk assembly may be a single disk or a two part disk assembly. The two part disk assembly allows adjustment of the bail bar relative to the biased brake rod assembly. Mechanical advantage may be achieved with the clutch disk assembly allowing greater or lesser braking force for the same actuation force of the bail bar. Braking bias force may be adjusted by positional adjustment of the spring cage or the spring retaining means. The braking system may be applied to one or more cart wheels, preferably two wheels.
Claims18
A braking mechanism comprising:
- a replaceable sacrificial brake shoe for imparting a braking force;
- said replaceable sacrificial brake shoe being removably connected to the distal end of a biased brake rod assembly further comprising—
- a biased brake rod bar;
- one or more supporting brackets;
- and
- a means of biasing the brake rod bar to provide the braking force;
- the proximal end of said biased brake rod assembly being communicatively interconnected to a rotational clutch assembly further comprising—
- a clutch disk having a pivot point;
- and
- said pivot point removably and rotationally engaging a clutch disk supporting bracket;
- and
- said clutch disk assembly being also communicatively interconnected to the distal end of a brake release bail bar assembly further comprising—
- a brake release bail bar;
- and
- one or more supporting brackets.
An automatically braked cart comprising:
- a cart body;
- a plurality of cart roller wheels coupled to, and supporting, said cart body such that the cart body may be moved by rotation of said cart roller wheels;
- and
- a braking mechanism including—
- a replaceable sacrificial brake shoe for imparting a braking force;
- said replaceable sacrificial brake shoe being removably connected to the distal end of a biased brake rod assembly further comprising—
- a biased brake rod bar;
- one or more supporting brackets;
- and
- a means of biasing the brake rod bar to provide the braking force;
- the proximal end of said biased brake rod assembly being communicatively interconnected to a rotational clutch assembly further comprising—
- a clutch disk having a pivot point;
- and
- said pivot point removably and rotationally engaging a clutch disk supporting bracket;
- and
- said clutch disk assembly being also communicatively interconnected to the distal end of a brake release bail bar assembly further comprising—
- a brake release bail bar;
- and
- one or more supporting brackets.
