초록 ▼

An automatic wheel chocking apparatus for restraining movement of a vehicle away from a loading dock during a loading operation. The apparatus comprises an elongated trough formed in the driveway that extends outwardly from the front face of the loading dock and a wheel chock is mounted in the trough for movement between a storage position, where the wheel chock is located beneath the level of a driveway, and an operative position where the chock extends upwardly above the driveway and is disposed to engage a wheel of a vehicle. The wheel chock is moved between the storage and operative positions by a drive mechanism that is located within the trough and includes a lead screw. A nut is threaded on the lead screw and is connected to the wheel chock via a rigid link. Rotation of the lead screw will move the chock between the storage and operative positions.

대표청구항 ▼

An automatic wheel chocking apparatus, comprising a generally horizontal supporting surface having a pocket therein, a wheel chock mounted on said supporting surface for movement from a storage position where said wheel chock is located within said pocket and beneath the level of said supporting surface to an operative position where said wheel chock is located within said pocket and beneath the level of said supporting surface to an operative position where said wheel chock is located above said supporting position and is disposed to engage a wheel of a vehicle, drive means for moving said wheel chock between the storage and operative positions and comprising a rotatable lead screw, a nut engaged with said lead screw, means for rotating said screw to thereby move said nut axially on said screw, and link means having a first end pivotally connected to said nut and having a second end pivotally connected to said wheel chock, wherein rotation of said screw in one direction moves said wheel chock from the storage position to the operative position and rotation of the lead screw in the opposite direction moves said wheel chock from the operative position to the storage position.
