Abstract
Provided are mechanical braking systems for wheeled trolleys, trolleys including a mechanical braking system and methods for controlling movement thereof.
Claims18
A wheeled trolley comprising:
- a platform base member;
- a wheel set defining a ground contact surface;
- and
- a foot lever articulated to the platform base member through a biasing mechanism, said foot lever being configured to have a first position in which it is not in contact with the ground contact surface, and a second position in which the lever is in contact with the ground contact surface, against a biasing effect of the biasing mechanism,
- wherein the foot lever is biased into said first position by the biasing mechanism, and
- wherein the biasing mechanism comprises a pivoting structure and a biasing member, the biasing member is an elastically deformable member disposed between a bottom face of the platform and a support member articulated to the pivoting structure.

A mechanical braking system for a wheeled trolley having a platform base member and a wheel set defining a ground contact surface, the mechanical braking system comprising:
- a foot lever articulable to the platform base member through a biasing mechanism, said foot lever being configured to have a first position in which it is not in contact with the ground contact surface, and a second position in which the lever is in contact with the ground contact surface, against a biasing effect of the biasing mechanism,
- wherein the foot lever is biased into said first position by the biasing mechanism, and
- wherein the biasing mechanism comprises a pivoting structure and a biasing member, the biasing member is an elastically deformable member being configured to be disposed between a bottom face of the platform and a support member articulated to the pivoting structure.
