Abstract

A loading dock having a dock face, a driveway positioned adjacent to the dock face, a wheel chock positioned above the driveway for movement relative to the driveway, and a power mechanism interconnected with the chock to provide power to the chock. The power mechanism is at least partially recessed within the driveway. Preferably, the power mechanism is spaced from the dock face so that vehicles having lift gates can be serviced under a variety of conditions. The power mechanism can be positioned within a housing that is also spaced from the dock face. The housing can include a ramped portion facing the dock face so that contact with the housing by a lift gate will be deflected.

Claims

1. A loading dock comprising:

a dock face;

a driveway positioned adjacent to said dock face;

a chock movable relative to said driveway from a stored position to a raised position, said chock being positioned above said driveway when in the stored position;

a power mechanism interconnected with said chock to provide power to said chock, said power mechanism being at least partially recessed within said driveway; and

a drive mechanism interconnecting said power mechanism with said chock, wherein said drive mechanism is positioned above said driveway.

2. A loading dock as claimed in claim 1, wherein said chock is movable from a lowered inoperative position to a raised operative position.

3. A loading dock as claimed in claim 2, wherein said chock is positioned above said driveway when in both the inoperative position and the operative position.

4. A loading dock as claimed in claim 1, further comprising a base frame positioned on said driveway, wherein said chock is positioned for movement over said base frame, and wherein said drive mechanism is at least partially positioned within said base frame such that wheels of a vehicle positioned at said loading dock will be positioned over at least a portion of said drive mechanism.

5. A loading dock as claimed in claim 1, wherein said drive mechanism includes a screw member, wherein said power mechanism includes a motor having an output shaft, and wherein said screw member is aligned with said output shaft.

6. A loading dock as claimed in claim 1, wherein said motor comprises an electric motor.

7. A loading dock as claimed in claim 1, wherein said power mechanism is spaced from said dock face.

8. A loading dock as claimed in claim 1, further comprising a housing in which said power mechanism is positioned.

9. A loading dock as claimed in claim 8, wherein said housing is spaced from said dock face.

10. A loading dock as claimed in claim 8, wherein said housing includes a ramped portion facing said dock face.

11. A loading dock comprising:

a dock face;

a driveway positioned adjacent to said dock face;

a chock movable from a lowered position where a vehicle wheel is capable of going on and over said chock to a raised position where said chock is able to prevent rotation of the vehicle wheel when said chock is placed against the vehicle wheel, said chock being movable relative to said driveway and positioned above said driveway in the lowered position and in the raised position; and

a power mechanism being at least partially recessed within said driveway; and

a drive mechanism interconnecting said power mechanism with said chock, wherein said drive mechanism is positioned above said driveway.

12. A loading dock as claimed in claim 11, further comprising a base frame positioned on said driveway, wherein said chock is positioned for movement over said base frame, and wherein said drive mechanism is at least partially positioned within said base frame such that wheels of a vehicle positioned at said loading dock will be positioned over at least a portion of said drive mechanism.

13. A loading dock as claimed in claim 11, wherein said drive mechanism includes a screw member, wherein said power mechanism includes a motor having an output shaft, and wherein said screw member is aligned with said output shaft.

14. A loading dock as claimed in claim 11, wherein said motor comprises an electric motor.

15. A loading dock as claimed in claim 11, wherein said power mechanism is spaced from said dock face.

16. A loading dock as claimed in claim 11, further comprising a housing in which said power mechanism is positioned.

17. A loading dock as claimed in claim 16, wherein said housing is spaced from said dock face.

18. A loading dock as claimed in claim 16, wherein said housing includes a ramped portion facing said dock face.
