Abstract
Storage racks include bays for accepting three loads of goods from an open front end wherein telescoping upper and lower trolleys move along a track assembly from the front of the bay rearward. The upper and lower trolleys are successively loaded, and they are moved rearward to rear and central locations as each following load is inserted, with a third load of goods being located on the track assembly in front of the two loaded trolleys. The track assembly is inclined downward toward the front of the bay, and catches are associated with the track assembly to prevent return movement of the loaded trolleys to the front of the bay until released.
Claims11
In a storage rack having bays for receiving at least two loads in a front location and at least one location rearward thereof, each bay comprising:
- an open front end through which loads may be supplied and withdrawn,
- rail means extending from said front location to said rearward location and being inclined downwardly towards said front end,
- trolley means for carrying a load, said trolley means being mounted on said rail means for movement therealong,
- catch means associated with said rail means for preventing forward movement of said trolley means when in said rearward location but permitting rearward movement of said trolley means when in said forward location,
- means to release said catch means, and
- means for supporting a load at said front location when said trolley is moved to said rearward location.
In a storage rack having bays for receiving three loads in a front location and having a rear location and an intermediate location, each bay comprising:
- an open front end through which said loads may be supplied and withdrawn;
- a pair of parallel, spaced-apart beams extending from said front location to said rear location and being inclined downwardly towards said front end, each beam having a flat upper surface with spaced apart edges, the outside edges of said beams providing an outside track and the inside edges providing an inside track;
- a first trolley for carrying a first load mounted for movement on said outside track between said front location and said rear location;
- a second trolley for carrying a second load mounted for movement on said inside track between said front location and said intermediate location, said second trolley being proportioned to fit beneath and inside said first trolley;
- PG,19
- means for supporting a third load at said front location when the two trolleys have been moved rearwardly;
- each trolley having a pair of laterally outwardly extending rear retainers and a pair of laterally outwardly extending front retainers said rear retainers having angled front and rear deflection surfaces, certain of said front retainers having angled rear deflection surfaces and front abutment surfaces extending substantially normal to the path of travel of said trolleys;
- hold down brackets overlying said retainers to prevent upward movement of said trolleys from said beams;
- a spring bumper positioned for engagement with one of said front retainers for cushioning and slowing a trolley as it approaches said front location;
- a catch means for each trolley to maintain the trolley remote from said front position until its return is called for, said catch means comprising a rotatable release rod carried extending rearwardly from said front location, said rod at its rear end having an upstanding tang for engaging an abutment surface of one of said front retainers, said rod at its front end having a handle to enable the operator to rotate said tang out of the path of the front retainer to permit the force of gravity to move the corresponding trolley to said front location;
- and
- a hysteresis wheel carried by each trolley adjacent one of its wheels and in peripheral engagement therewith to limit the speed of the trolley.
