First Claim
1. In combination, a loading dock having a vertical dock face and a vehicle supporting surface extending outwardly from said dock face, vehicle locking means mounted on said supporting surface for locking a vehicle against outward movement away from said dock face and including guide track means, wheel chock means mounted for movement on said guide track means between a storage position where said wheel chock means will not obstruct movement of a vehicle on said supporting surface, and an operative position where said wheel chock means extends upwardly above said supporting surface and is disposed to engage a wheel of a vehicle to prevent movement of said vehicle away from said dock face, and drive means operably connected to said wheel chock means for moving said wheel chock means between the storage and operative positions, said drive means comprising a fluid cylinder unit including a cylinder member and a piston member, said members being mounted for movement relative to each other, a first of said members being fixed relative to said guide track means and a second of said members being operably connected to said wheel chock means, said fluid cylinder unit being constructed and arranged such that movement of said second member relative to said first member will move said wheel chock means between the storage and operative positions.

9. In combination, a loading dock having a vertical dock face and a vehicle supporting surface extending outwardly from said dock face, vehicle locking means mounted on said supporting surface for locking a vehicle against outward movement away from said dock face and including guide track means, wheel chock means mounted for movement on said guide track means between a storage position where said wheel chock means will not obstruct movement of a vehicle on said supporting surface, and an operative position where said wheel chock means extends upwardly above said supporting surface and is disposed to engage a wheel of a vehicle to prevent movement of said vehicle away from said dock face, and drive means operably connected to said wheel chock means for moving said wheel chock means between the storage and operative positions, said drive means including a flexible drive member disposed in a generally endless configuration and attached to said wheel chock means, connecting means for connecting a portion of said flexible drive member to a fixed location, said drive means also including a fluid cylinder unit operably connected to said flexible drive member at a location spaced between said connecting means and the attachment of said drive member to said wheel chock means, said fluid cylinder unit being constructed and arranged such that operation of said cylinder unit will move said wheel chock means between the storage and operative positions.
- 10. In combination, a loading dock having a vertical dock face and a driveway extending outwardly from said dock face, said driveway having a recess therein, support means for supporting a vehicle and disposed in said recess, mounting means for mounting the support means for vertical movement in said recess, operating means for moving said support means vertically in said recess, guide track means in said support means, wheel chock means mounted for movement on said guide track means between a storage position where said wheel chock means will not obstruct movement of a vehicle across said support means and an operative position where said wheel chock means extends upwardly above said support means and is disposed to engage a wheel of a vehicle located on said support means, and drive means operably connected to said wheel chock means for moving the wheel chock means between the storage and operative position, said drive means including a first fluid cylinder unit comprising a cylinder member and a piston member, said members being mounted for movement relative to each other, a first of said members being connected to said support means and a second of said members being operably connected to said wheel chock means, said members being constructed and arranged such that relative movement of said members will move said wheel chock means between the storage and operative positions.
