Abstract

Claims (46)

1 . A dock leveler comprising:

a lift lever operably graspable by a user to lift, lower, and extend the dock leveler; and

a lift lever retainer having an opening shaped and sized to slidably receive the lift lever, the lift lever comprising:

a top portion including a handle graspable by the user;

a middle portion adjacent the top portion;

a bottom portion adjacent the middle portion, the bottom portion engageable with the lift lever retainer when lifting, lowering, or extending the dock leveler; and

a stopper disposed on the middle portion or on the top portion, wherein a combined width of the lift lever and the stopper is greater than a width of the opening of the lift lever retainer, and wherein the lift lever is movable to a stowed position where the lift lever is received in the lift lever retainer and the bottom portion is unengaged from the lift lever retainer.

2 . The dock leveler of claim 1 , wherein the stopper is sized larger than the opening of the lift lever retainer in a manner that prevents portions of the lift lever above the stopper from sliding downwardly through the opening of the lift lever retainer.

3 . The dock leveler of claim 1 , wherein the stopper is located on the lift lever at a position that prevents contact between the handle and the lift lever retainer when the lift lever is moved to a stowed position.

4 . The dock leveler of claim 3 , wherein the stopper is configured to absorb an impact force generated when the lift lever is dropped through the lift lever retainer.

5 . The dock leveler of claim 3 , wherein the stopper is formed of a material different than a material of the lift lever retainer.

6 . The dock leveler of claim 5 , wherein the stopper is a polymer, and the lift lever retainer is a metal.

7 . The dock leveler of claim 1 , wherein the handle forms a first angle between a first side of the handle and the lift lever and a second angle between a second side of the handle and the lift lever, the first angle being smaller than the second angle.

8 . The dock leveler of claim 7 , wherein the stopper is disposed on the first side of the handle and/or the first side of the lift lever.

9 . The dock leveler of claim 1 , wherein the stopper is a metal or a metal alloy.

10 . The dock leveler of claim 1 , wherein an end cap is disposed on a top end of the handle.

11 . A dock leveler comprising:

a selectively stowable lift lever operably graspable by a user to lift, lower, and extend the dock leveler; and

a lift lever retainer having an opening shaped and sized to slidably receive the lift lever, the lift lever comprising:

a top portion including a handle graspable by the user;

a middle portion adjacent from the top portion having a first hole configured to receive a first blocking mechanism to prevent portions of the lift lever above the first hole from sliding downwardly through the opening of the lift lever retainer, wherein the first blocking mechanism is removably coupled to the dock leveler; and

a bottom portion adjacent the middle portion, the bottom portion engageable with the lift lever retainer when lifting, lowering, and extending the dock leveler.

12 . The dock leveler of claim 11 , wherein when the bottom portion of the lift lever has engaged the opening of the lift lever retainer and the first hole has received the first blocking mechanism, the lift lever is configured to be:

used to operate the dock leveler;

stowed in a raised position; and/or

removed from the lift lever retainer.

13 . The dock leveler of claim 11 , wherein a width of the first blocking mechanism is greater than a width of the opening of the lift lever retainer.

14 . The dock leveler of claim 11 , wherein the first hole is in a bottom end of the middle portion of the lift lever.

15 . The dock leveler of claim 11 , wherein the bottom portion has a second hole configured to receive a second blocking mechanism to prevent the portions of the lift lever above the second hole from sliding upwardly through the opening of the lift lever retainer.

16 . The dock leveler of claim 15 , wherein when the bottom portion of the lift lever has engaged the opening of the lift lever retainer and the second hole has received the second blocking mechanism, the lift lever is configured to be:

used to operate the dock leveler;

stowed in a lowered position; and/or

irremovable from the lift lever retainer.

17 . The dock leveler of claim 15 , wherein when the bottom portion of the lift lever has engaged the opening of the lift lever retainer, the first hole has received the first blocking mechanism, and the second hole has received the second blocking mechanism, the lift lever is configured to be:

used to operate the dock leveler;

stowed in a raised position; and/or

irremovable from the lift lever retainer.

18 . The dock leveler of claim 15 , wherein a width of the second blocking mechanism is greater than a width of the opening of the lift lever retainer.

19 . A dock leveler comprising:

a lift lever operably graspable by a user to lift, lower, and extend the dock leveler; and

a lift lever retainer having an opening shaped and sized to slidably receive the lift lever, the lift lever comprising:

a top portion including a handle graspable by the user;

a middle portion adjacent from the top portion; and

a bottom portion engageable with the lift lever retainer when lifting, lowering, and extending the dock leveler,

wherein the lift lever further comprises a stopper, and wherein a combined width of the lift lever and the stopper is greater than a width of the opening of the lift lever retainer, and wherein the lift lever is movable to a stowed position where the lift lever is received in the lift lever retainer and the bottom portion is unengaged from the lift lever retainer or

wherein the middle portion has a hole configured to receive a blocking mechanism to prevent portions of the lift lever above the hole from sliding downwardly through the opening of the lift lever retainer, wherein the hole is configured to removably couple the blocking mechanism to the dock leveler.
