Abstract

A dock leveler comprises a maintenance strut rotatable between a maintenance position and a stowed position, the maintenance strut being configured to secure the dock leveler in an accessible position when in the maintenance position. The maintenance strut has a latch hole and a pivot hole formed therein. The dock leveler further comprises a latch configured to selectively maintain the maintenance strut in the maintenance position or the stowed position. The latch comprises a pin selectively extendable through the latch hole, the pin having a first end and a second end, and a retainer having a first end fixedly attached to the first end of the pin and a second end selectively attachable to the second end of the pin.

First claim

What is claimed is:

1 . A dock leveler comprising:
a maintenance strut rotatable between a maintenance position and a stowed position, the maintenance strut being configured to secure the dock leveler in an accessible position when in the maintenance position, the maintenance strut having a latch hole and a pivot hole formed therein; and a latch configured to selectively maintain the maintenance strut in the maintenance position or the stowed position, the latch comprising:
a pin selectively extendable through the latch hole, the pin having a first end and a second end; and
a retainer having a first end fixedly attached to the first end of the pin and a second end selectively attachable to the second end of the pin.

2 . The dock leveler of claim 1 , further comprising a distally projecting gusset plate and a pivot shaft, the maintenance strut being rotatably coupled to the distally projecting gusset plate by the pivot shaft.

3 . The dock leveler or claim 2 , further comprising a face plate abuttable against a dock, the distally projecting gusset plate being fixed to the face plate.

4 . The dock leveler of claim 2 , wherein the distally projecting gusset plate comprises a latch hole, the pin further selectively extendable through the latch hole in the distally projecting gusset plate.

5 . The dock leveler of claim 1 , further comprising a pivot shaft extending through the pivot hole in the maintenance strut, the maintenance strut rotatable about the pivot shaft between the maintenance position and the stowed position.

6 . The dock leveler of claim 1 , wherein the stowed position is a hanging position.

7 . The dock leveler of claim 1 , wherein the maintenance position is an upright position.

8 . The dock leveler of claim 7 , wherein when the latch is configured to maintain the maintenance strut in the upright position, the maintenance strut is configured to hold the dock leveler in a lifted position.

9 . The dock leveler of claim 8 , wherein when the maintenance strut is configured to hold the dock leveler in the lifted position, the maintenance strut extends higher than a deck plate of the dock leveler.

10 . The dock leveler of claim 1 , wherein the second end of the retainer is selectively attachable to the second end of the pin through an opening in the second end of the retainer.

11 . The dock leveler of claim 10 , wherein the second end of the retainer includes a tab to facilitate the selective attachment of the retainer to the second end of the pin.

12 . The dock leveler of claim 1 , wherein the retainer is semi-circular in shape.

13 . A method comprising:
rotatably coupling a maintenance strut to a dock leveler between a maintenance position and a stowed position, the maintenance strut being configured to secure the dock leveler in an accessible position when in the maintenance position, the maintenance strut having a latch hole and a pivot hole formed therein; and selectively maintaining the maintenance strut in the maintenance position or the stowed position using a latch, the latch comprising:
a pin extendable through the latch hole, the pin having a first end and a second end; and
a retainer having a first end fixedly attached to the first end of the pin and a second end selectively attachable to the second end of the pin.

14 . The method of claim 13 , wherein when the maintenance strut is maintained in the maintenance position, the dock leveler cannot be extended or lowered.

15 . The method of claim 13 , wherein when the maintenance strut is maintained in the stowed position, the dock leveler can be lowered, extended. or lifted.

16 . The method of claim 13 , wherein selectively attaching the second end of the retainer to the second end of the pin includes pushing an opening defined by the second end of the retainer over the second end of the pin.

17 . The method of claim 16 , wherein the second end of the retainer includes a tab used to push the opening defined by the second end of the retainer over the second end of the pin.

18 . A dock leveler comprising:
a face plate disposable adjacent a dock wall; a gusset plate extending from the face plate, the gusset plate comprising a pivot hole and a latch hole; a maintenance strut rotatable between a maintenance position and a stowed position, the maintenance strut being in an upright position configured to secure the dock leveler in an accessible position, the maintenance strut having a pivot hole and a latch hole formed therein; a pivot shaft extending through the pivot hole in the gusset plate and the pivot hole in the maintenance strut, the maintenance strut being rotatable about the pivot shaft; and a latch configured to selectively maintain the maintenance strut in the maintenance position, the latch comprising a pin extendable through the latch hole in the gusset plate and the latch hole in the maintenance strut.

19 . The dock leveler of claim 18 , further comprising a deck plate, the maintenance strut having a length greater than a width of the deck plate.

20 . The dock leveler of claim 19 , further comprising a lip plate attached to the deck plate, the maintenance strut being shorter than a height of the lip plate when the maintenance strut is in the maintenance position.
