ABSTRACT:
The present invention provides a braking mechanism for a castor, which includes a wheel support, two wheels and a brake support. Wherein the wheel support contains an axle suspension with a housing holding a spring and a slide therein. A slotted hole is formed through respective sides of the axle suspension, and two transverse stoppers are respectively formed on the top and bottom portions of the axle suspension, immediately above and below the slotted hole. The brake support extends outwardly to form two flat plates on respective sides thereof and spaced to extend on a respective side wall of the axle suspension, between the upper and lower stoppers. Each plate has a diagonally directed slotted hole formed therethrough for an axle to pass therethrough, through the slotted hole of the axle suspension and through the internal slide. The bias of the spring displaces the axle to the bottom of the slots, displacing the brake support to engage stopping recesses formed in the wheels to latch them against rotation. The brake support is disengaged by application of a downward force on the wheel support sufficient to overcome the spring bias force.
