Abstract

An accessory arm for a lift truck includes at least one rear attachment mechanism affixed to a rear overhead guard leg of the lift truck and a front attachment mechanism affixed to a front overhead guard leg of the lift truck. The accessory arm further includes an accessory bar rotationally mounted to the at least one rear attachment mechanism and to engage with the front attachment mechanism when the accessory bar is in a closed position. A wiring harness connected to a battery of the lift truck and routed within the accessory bar to a device mounted to the accessory bar, the wiring harness to provide power to the device.

2. The accessory arm of claim 1, wherein the at least one mount comprises a clamping device configured to releasably attach the at least one mount to the accessory bar at one or more locations along a length of the accessory bar.

3. The accessory arm of claim 1, wherein the elongated accessory holder comprises:

a back portion extending substantially vertically down from the accessory arm;

a bottom portion extending away from the back portion at an upward angle with respect to the back portion; and

a central extrusion extending from the bottom portion towards the back portion, wherein the central extrusion is angularly offset from the bottom portion such that an outer surface of the central extrusion is substantially parallel with the back portion.

4. The accessory arm of claim 3, wherein the central extrusion comprises:

a conical S-shaped cross section that is larger proximate the bottom portion than distal from the bottom portion.

5. The accessory arm of claim 3, wherein the elongated accessory holder further comprises a slanted portion that extends between the back portion and the accessory arm, and wherein a mounting extrusion is formed in the slanted portion and extends substantially vertically from the slanted portion.

6. The accessory arm of claim 1, wherein:

the at least one rear attachment mechanism comprises an upper rear attachment mechanism and a lower rear attachment mechanism.

7. The accessory arm of claim 6, further comprising an extension plate that extends between the upper rear attachment mechanism and the lower rear attachment mechanism, wherein the extension plate maintains a distance between the upper rear attachment mechanism and the lower rear attachment mechanism.

8. The accessory arm of claim 6, wherein:

the upper rear attachment mechanism comprises an upper mounting plate that includes an aperture sized and shaped to receive a hooked end of a dock plate tool; and

the lower rear attachment mechanism comprises a lower mounting plate that includes a bracket sized and shaped to retain a handle of the dock plate tool such that movement of the dock plate tool handle is inhibited when retained by the bracket.

9. The accessory arm of claim 6, wherein the accessory bar includes a first L-shaped portion and a second L-shaped portion, wherein a substantially vertical portion of the first L-shaped portion extends along the rear overhead guard leg and a substantially horizontal portion of the first L-shaped portion extends substantially perpendicularly from the substantially vertical portion, and wherein a substantially horizontal portion of the second L-shaped portion is affixed to the substantially vertical portion of the first L-shaped portion and extends substantially perpendicularly from the substantially vertical portion of the first L-shaped portion and a substantially vertical portion of the second L-shaped portion is affixed to the substantially horizontal portion of the first L-shaped portion and extends substantially perpendicularly from the substantially horizontal portion of the first L-shaped portion, and wherein the mount is attached to the second L-shaped portion of the accessory bar.

10. The accessory arm of claim 1, wherein the front attachment mechanism comprises a handle retaining bracket and the accessory arm further comprises a cradle sized and shaped to be affixed to the lift truck, the handle retaining bracket and the cradle cooperating to hold a load bar tool when the accessory arm is affixed to the lift truck.

11. The accessory arm of claim 1, further comprising a wiring harness routed within the accessory bar to an accessory affixed to the accessory bar, the wiring harness sized and shaped to connect to a battery of the lift truck to provide power to the accessory.

12. The accessory arm of claim 11, further comprising an electrical socket mounted on an exterior of the accessory bar, wherein the wiring harness is routed within the accessory bar to the electrical socket and is electrically coupled to the electrical socket.

13. The accessory arm of claim 1, wherein the accessory bar is rotationally mounted to the at least one rear attachment mechanism such that the second portion of the latch mechanism is at a vertically elevated position when the accessory bar is at an open position compared to when the accessory bar is at a closed position.

14. The accessory arm of claim 1, wherein the accessory bar includes a plurality of apertures formed along a length of the accessory bar, and wherein the second mount is affixed to the accessory bar by one or more fasteners that engage with at least one aperture of the plurality of apertures.

15. An accessory arm for a lift truck, comprising:

at least one rear attachment mechanism sized and shaped to be affixed to a rear overhead guard leg of a lift truck;

a front attachment mechanism sized and shaped to be affixed to a front overhead guard leg of the lift truck, the front attachment mechanism including a first portion of a latch mechanism;

an accessory bar rotationally mounted to the at least one rear attachment mechanism and including a second portion of the latch mechanism configured to releasably engage the first portion of the latch mechanism when the accessory bar is in a closed position; and

at least one mount releasably attached to the accessory bar, the at least one mount sized and shaped to affix an accessory to the accessory bar such that the accessory is positionable at a user selected position, wherein the at least one rear attachment mechanism comprises an upper rear attachment mechanism and a lower rear attachment mechanism, wherein the upper rear attachment mechanism comprises an upper mounting plate that includes an aperture sized and shaped to receive a hooked end of a dock plate tool, and wherein the lower rear attachment mechanism comprises a lower mounting plate that includes a bracket sized and shaped to retain a handle of the dock plate tool such that movement of the dock plate tool handle is inhibited when retained by the bracket.

16. The accessory arm of claim 15, wherein the accessory bar includes a first L-shaped portion and a second L-shaped portion, wherein a substantially vertical portion of the first L-shaped portion extends along the rear overhead guard leg and a substantially horizontal portion of the first L-shaped portion extends substantially perpendicularly from the substantially vertical portion, and wherein a substantially horizontal portion of the second L-shaped portion is affixed to the substantially vertical portion of the first L-shaped portion and extends substantially perpendicularly from the substantially vertical portion of the first L-shaped portion and a substantially vertical portion of the second L-shaped portion is affixed to the substantially horizontal portion of the first L-shaped portion and extends substantially perpendicularly from the substantially horizontal portion of the first L-shaped portion, and wherein the mount is attached to the second L-shaped portion of the accessory bar.
