Abstract

A ladder cage is provided. The ladder cage includes opposite first and second sidewalls each extending parallel to a longitudinal axis. Spaced apart brackets are coupled to one of the sidewalls. Spaced apart rollers extend between the sidewalls. The rollers are each rotatable relative to the sidewalls along a rotation axis that extends transverse to the longitudinal axis. The rollers and inner surfaces of the brackets and the sidewalls define a housing configured for disposal of a ladder.

wherein the rollers and inner surfaces of the brackets and the sidewalls define a housing configured for disposal of a ladder.

2. A ladder cage as recited in claim 1 , where the rollers include a rear roller positioned at distal ends of the sidewalls and a front roller positioned between proximal ends of the sidewalls and the distal ends, the rear roller having a diameter that is greater than that of the front roller.

3. A ladder cage as recited in claim 1 , where the rollers include a rear roller positioned at distal ends of the sidewalls, a front roller positioned between proximal ends of the sidewalls and the distal ends and an intermediate roller positioned between the rear and front rollers, the rear roller having a diameter that is greater than that of the front roller and the intermediate roller.

4. A ladder cage as recited in claim 1 , where the brackets each include a first portion that engages one of the sidewalls and a second portion that extends transverse to the first portion, the second portion comprising a flange that extends parallel to the first portion, the flange comprising an opening configured for disposal of a fastener.

5. A ladder cage as recited in claim 1 , further comprising an end stop coupled to proximal ends of the sidewalls, the end stop having a maximum height that is greater that of the sidewalls.

6. A shelving system comprising:

a shelving unit comprising:

first and second side members,

a cross member extending between and connecting the first side member with the second side member, and

a container including a pair of spaced apart side walls, one of the side walls being movably coupled to the cross member; and

the ladder cage recited in claim 1 coupled to the first and second side members.

7. A shelving system as recited in claim 6 , wherein a first end of the ladder cage is supported entirely by the first and second side members.

8. A shelving system as recited in claim 7 , wherein a second end of the ladder cage is supported by a second shelving unit.

9. A shelving system as recited in claim 6 , wherein one of the brackets is coupled to the first side member and comprises a first arm that engages a proximal portion of the first side member and a second arm that engages a distal portion of the first side member, the first arm extending perpendicular to the first side member and the second arm extending at an acute angle relative to the first side member.

10. A shelving system as recited in claim 9 , wherein one of the brackets is coupled to the second side member and comprises a first arm that engages a proximal portion of the second side member and a second arm that engages a distal portion of the second side member, the first and second arms of the bracket that engages the second side member extending perpendicular to the second side member.

11. A shelving system as recited in claim 6 , wherein the ladder cage is coupled directly to the first and second side members by fasteners that each extend through one of the first and second side members and the ladder cage.

12. A shelving system as recited in claim 6 , wherein the ladder cage comprises a bottom panel extending between and connecting the first and second sidewalls, wherein inner surfaces of the brackets engage an outer surface of the bottom panel.

13. A shelving system as recited in claim 6 , further comprising a tubular carrier coupled directly to the first and second side members, the carrier comprising an inner surface defining a conduit.

14. A shelving system as recited in claim 13 , wherein the carrier comprises a first end having a first opening that is in communication with the conduit and an opposite second end, the carrier further comprising a locking hinged lid configured to removably cover the first opening.

15. A shelving system as recited in claim 6 , wherein the first side member extends parallel to the second side member and a has a maximum height that is equal to that of the second side member.

16. A shelving system as recited in claim 6 , further comprising a top mounting bracket mounted to top ends of each of the first and second side members, the top mounting bracket being configured to be mounted on a frame of a vehicle that supports a side panel of the vehicle such that the first and second side members are each spaced apart from the frame and the side panel.

17. A shelving system as recited in claim 6 , wherein:

the first and second side members each include a first channel;

the cross member defines a second channel having a guide member movably disposed therein, the guide member comprising a third channel; and

the side walls of the container each comprise a rail, one of the rails being movably disposed in the third channel, at least one of the rails including a first locking element and a second locking element that is connected to the first locking element, the container including a handle comprising a third locking element that engages a first end of the first locking element, the locking elements being configured to provisionally fix the container relative to the guide member.

18. A shelving system comprising:

a ladder;

a first shelving unit comprising:

first and second side members,

a first cross member extending between and connecting the first side member with the second side member, and

a first container including a pair of spaced apart first side walls, one of the first side walls being movably coupled to the first cross member;

a second shelving unit that is spaced apart from the first shelving unit, the second shelving unit comprising:

third and fourth side members and a vertical member that is aligned with the third and fourth members along a transverse axis,

a second cross member extending between and connecting the third side member with the fourth side member, the second cross member being spaced apart from the vertical member, and

a second container including a pair of spaced apart second side walls, one of the second side walls being movably coupled to the second cross member;

a cage having a first end coupled to the first and second side members and a second end coupled to the vertical member, the cage comprising a tray and a bracket that is coupled to the tray such that inner surfaces of the tray and the bracket define a housing configured for disposal of the ladder; and

a tubular carrier having a first end coupled to the first and second side members and a second end coupled to a mounting bracket of the second shelving unit, the mounting bracket being coupled to a lateral member that extends perpendicular to the third and fourth side members, the carrier comprising an inner surface defining a conduit.

19. A shelving system comprising:

a vehicle comprising an interior including a floor and first and second side panels, the interior being accessible through at least one rear door positioned between the first and second side panels and at least one side door that extends through one of the first and second side panels;
