Abstract
The braking system for movable container or trolley (1) is formed from three different, separate modules, namely in each case one brake module (20) on each brakeable wheel, at least one pedal module (30) and a connecting and transmission module (40) with sliding rods (42) connecting the pedal modules to all the brake modules. The brake module is operated by means of working surfaces (46) on the sliding rods (42) and has a lifting device (22) for operating the wheel brake (25). This leads to a rational, easily installable and easily operable braking system with reliable braking characteristics.
Claims21
In combination,
- a trolley having base plate and a plurality of wheel units mounted on an underside of the said base plate;
- a braking system for braking and unbraking of at least some of said wheel units, said braking system including
- at least one pedal module mounted on said base plate and including a brake operating pedal and a brake release pedal;
- a transmission module including a pair of parallel rods slidably mounted relative to said base plate and at least one pivotally mounted operating lever in contact with each of said rods to transfer only a compressive force to each rod in response to pivoting of said layer, each said pedal of said pedal module being in contact with an opposite side of said operating lever from the other of said pedals to pivot said operating lever only under a compressively applied force from said respective pedal and to effect horizontal longitudinal movement of each of said parallel rods;
- and
- at least a pair of independently mounted brake modules, each said brake module being disposed at a respective one of said wheel units and including a brake block for engaging and braking said respective one of said wheel units and a firing device articulated to a respective sliding rod for moving said brake block into engagement with said respective one of said wheel units in response to longitudinal movement of said respective rod in one direction under a compressive force therein and for removing said brake block from engagement with said respective one of said wheel units in response to longitudinal movement of said respective rod in an opposite direction to said one direction.

In combination
- a trolley having at least one wheel unit mounted on an underside thereof;
- and
- a brake system for braking and unbraking of said wheel unit, said braking system including
- at least one pedal module mounted on said trolley and including a brake operating pedal and a brake release pedal;
- a transmission module including at least one pivotally mounted operating lever in contact with each said pedal to receive only a compressive force from each said pedal in response to movement of a respective pedal and at least one longitudinally movable rod in contact with said layer to receive only a compressive force from said lever in response to pivoting of said lever for horizontal longitudinal movement thereof in response to a compressively applied force from a respective pedal;
- and
- a brake module including a brake block for engaging and braking said wheel unit and a lilting device articulated to said rod for moving said block into engagement with said wheel unit in response to actuation of said brake operating pedal and longitudinal movement or said rod in one direction under a compressive force therein and for moving said block from engagement with said wheel unit in response to actuation of said brake release pedal and longitudinal movement of said rod in an opposite direction to said one direction.
