Vehicle wheel chock

A wheel chock for preventing rotation and shifting motion of a wheel on a supporting structure having a plurality of openings extending therethrough, the wheel chock comprising:

• a base member having a front and a rear end;
• a plurality of spaced apart clamping teeth extending downwardly and forwardly from the base member front end for sliding insertion into the supporting structure openings and under the supporting structure in a direction toward the wheel and for sliding extraction from the supporting structure openings in a direction away from the wheel;
• articulated locking means attached to the base member adjacent the rear end thereof, the articulated locking means comprising a hooking finger for insertion into and engagement with a supporting structure opening other than the supporting structure openings wherein the clamping teeth are inserted;
• a plurality of arresting studs depending downwardly from the base member for insertion into the supporting structure openings other than the supporting structure openings wherein the clamping teeth are inserted to further prevent movement of the wheel chock;
• means for engaging and disengaging the hooking finger relative the supporting structure opening to prevent and allow movement of the wheel chock, respectively;
• face plate means supported by the base member for contact with the wheel to prevent rotation thereof;
• and
• restraining means extending from the face plate means for contact with the wheel to prevent shifting motion thereof.

A wheel chock for preventing rotation and shifting motion of a wheel on a supporting structure having a plurality of openings extending therethrough, the wheel chock comprising:

• a base member having a front and a rear end and a load transfer wall integrally formed with the base member front end;
• a plurality of spaced apart clamping teeth extending downwardly and forwardly from the base member front end for sliding insertion into the supporting structure openings and under the supporting structure in a direction toward the wheel and for sliding extraction from the supporting structure openings in a direction away from the wheel;
• articulated locking means attached to the base member adjacent the rear end thereof, the articulated locking means comprising a hooking finger for insertion into a supporting structure opening other than the supporting structure openings wherein the clamping teeth are inserted and for engagement under the supporting structure proximate the supporting structure opening;
• a plurality of arresting studs depending downwardly from the base member for insertion into the supporting structure openings other than the supporting structure openings wherein the clamping teeth are inserted;
• means for engaging and disengaging the hooking finger relative its supporting structure opening to prevent and allow movement of the wheel chock, respectively,
• the engaging and disengaging means further comprising a lever having an engaged and disengaged position coupled with a rotatable rod having a cam portion thereon, and a cam latch plate hingedly mounted at an upper portion thereof to a hinge pin attached to the base member, the cam latch plate having a lower edge from which the hooking finger extends and a cam engaging bore through which the cam portion of the rotatable rod projects, such that rotation of the cam portion rotates the cam latch plate about the hinge pin,
• the lever, when rotated to its engaged position, rotating the cam portion of the rotatable rod to engage the hooking finger of the cam latch plate with its supporting structure opening, and
• the lever, when rotated to its disengaged position, rotating the cam portion of the rotatable rod to disengage the hooking finger from its supporting structure opening;
• the lever further having a lift position whereat the hooking finger is disengaged from its supporting structure opening and the chock further having a means for extracting the articulated locking means, the extracting means including a lifter cam rotatably coupled with the rotatable rod;
• the lever, when rotated to the lift position, causing the lifter cam to protrude below the base member to contact the supporting structure and urge the base member rear end above the supporting structure such that the hooking finger and the arresting studs are extracted from their supporting structure openings, permitting the chock to be pulled away from the supporting structure and the clamping teeth to be extracted from under the supporting structure openings in the direction away from the wheel;
• a compressor element coupled to the rotatable rod and engaging a resilient member when the lever is pivoted to the lift position, the resilient member applying a rotational force to the rotatable rod to restore the lever to the disengaged position when the lever is released, thereby rotating the lifter cam to a retracted position and allowing the hooking finger and arresting studs to re-engage their supporting structure openings;
• face plate means supported by the base member for contact with the wheel to prevent rotation thereof when the lever is in the engaged position, the face plate means further comprising a load transfer member having an articulated first end hingedly connected to the base member rear end and an articulated second end hingedly connected to a face plate, inclination adjustment studs connected to the face plate, and a plurality of vertically arranged openings on the load transfer wall of the base member front end, the load transfer wall openings receiving the inclination adjustment studs to adjust the vertical position of the face plate in contact with the wheel relative the supporting structure;
• and
• restraining means extending from the face plate means for contact with the wheel to prevent shifting motion thereof when the lever is the engaged position.
