Wheel chock restraint system comprising a wheel chock, a supporting element mounted on the ground in vicinity of a loading dock and a wheel chock support assembly connected by one end to the wheel chock and by another end in vicinity of the loading dock. A base portion of the chock is provided with first engagement elements and the supporting elements are provide with corresponding second engagement elements. The first engagement elements are adapted to cooperate with the second engagement elements, thus creating a retention force directed away from the loading dock and preventing the chock from sliding away from the wheel of a vehicle making an attempt to depart prematurely from the loading dock. Wheel chock support assembly is adapted to ensure a secure positioning of the chock under the wheel of the vehicle during loading and unloading operation by creating an engagement force directed towards the loading dock and pressing the chock against the wheel. The first engagement elements comprise a plurality of teeth extending downwardly from the base portion of the chock under a predetermined angle and the second engagement elements are a plurality of stoppers extending upwardly from the supporting element.

A wheel chock for restraining movement of a vehicle tire on a supporting grating during transit includes a base, a grate lock mechanism for locking the base to the grating, and a ramp on the base for engagement with a circumference of a vehicle tire. A strap connected with the base is extensible around the vehicle tire to help restrain movement of the tire on the grating. The chock includes a retractor for retracting the strap and for taking up slack that forms in the strap during transit.

A boat rack apparatus for carrying a boat on a vehicle roof rack includes a plurality of conformable support members. Each support member has an expanse that contacts a boat hull. The expanse is supported by a rib arrangement, including a spring rib and a load rib. The spring rib underlies a flexible portion of the expanse. The load rib provides vertical support to the expanse. The support member adapts to different boat hull shapes.

A wheel chock apparatus includes a chock body for chocking a tire of a vehicle such as a semi-trailer prior to loading or unloading the trailer by a towmotor at a docking bay. When properly positioned, the chock body prevents movement of the vehicle away from the docking bay during the loading or unloading operation. Such movement poses a possible hazard to the cargo being loaded or unloaded, to the equipment performing the loading/unloading operations, and to the operator of such equipment. The chock body includes a sensor mounted on or embedded in the body, which is capable of detecting a properly chocked tire. The sensor is electrically connected to a microcontroller programmed to control an indicator, such as a visual light or audible alarm, that will alert an equipment operator on the docking bay as to whether the driver of the vehicle has properly chocked the tires.

The dual purpose track comprises a unitary elongated body having a longitudinal axis and a raised center section extending along the axis from one end to the other. The center section includes a flat base with downwardly tapering sides terminating in laterally outwardly extending flanges. The flat base which extends along the longitudinal axis is provided with longitudinally spaced apart elongated slots, as an example, spaced every four inches, which extend lengthwise along the axis. Each slot is configured to receive either the head of the bolt of a wheel chock used to retain a dirt bike along the floor of a trailer or a tie down fastening device. A strap is connected between the tie down device and the handle bar of the dirt bike to assist in retaining the bike in a fixed position. Thus, the track serves two purposes, namely, it holds the wheel chocks and the anchoring devices for the straps.

A wheel restraint includes a wheel chock that is manually movable between a retracted position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the retracted position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its retracted position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its retracted position, the locking feature automatically disengages. Although the wheel chock is connected to a track, most of the force exerted by the wheel against the chock is transmitted directly from the chock to the driveway.

A wheel-activated vehicle restraint system including a support structure disposed beside the path of the vehicle approaching the dock, and including a guide member extending away from the dock face, and an elevated supporting member. A trigger assembly is operatively connected to the guide member, and initially engages the wheel of the vehicle as it rolls toward the dock. A locking arm operatively engages the supporting member to move from a stored position to a chocking position on the wheel as the wheel engages the trigger and moves it toward the dock. A trolley assembly operatively connects the trigger assembly and the locking arm, the trolley assembly and the locking arm being connected at a connection point. The trigger assembly is selectively positionable relative to the connection point in response to the dimensions of the wheel, and the locking arm engages a bottom portion of the wheel, and moves along the peripheral surface of the wheel to a chocking position as the wheel continues to push the trigger assembly toward the dock.

The invention is a safety lock applied to a vehicle wheel during a road stop to prevent the vehicle from moving or being driven away during the stop. This safety lock would be applied to any tire on the vehicle by law enforcement or safety inspectors during the stop, the safety lock slid onto the tire from the outside of the tire, with friction enhanced chocks in front and in back of the tire, locking onto the tire to prevent the rotation of the tire, reducing the risk of injury or escape in the event an attempt is made to drive away during the road stop. It may also be used to secure a tire or wheel during maintenance or during an emergency roadside repair, the device compact enough to fit in the trunk of a car and light enough in weight to be carried by an average individual.

A configurable wheel lock comprising a rigid chock and an adjustable fork pivoted to the chock that engages a wheel seated within a cradle. The fork projecting from the control portion mounts a pair of separate arms pivoted to opposite ends of an axle that is slidably captivated within guide slots in the chock sides. Projecting arm stubs are inserted within the wheel to be captivated for locking. The fork arms rotate in a first plane that is coplanar with both arms and the axle, and they may be rotated about the axle. These combined rotational features enhance the positional abilities of the arms, and the dexterity of the wheel lock. Rigid locking-links pivoted to at least one of the arms are extended to the opposite arm to lock it in a selected locking position about the wheel.

Disclosed is a rack for supporting a vehicle, such as a motorcycle, during shipping. In one embodiment, the rack includes selectively actuated support assemblies, each having a rotatably mounted wheel. In the actuated position, the wheels facilitate movement of the rack and vehicle together. In this and possibly another embodiment, the rack includes a protective assembly having an upstanding guard mounted on opposed sides of a base in the form of a generally rectangular frame. Each protective assembly with the upstanding guard may move between a first, retracted position adjacent to the corresponding side of the frame and a second, extended position farther away from that side of the frame. The guard is also collapsible, including when the protective assembly is in the retracted position, to provide the rack with a low profile when not in use. Related methods are also disclosed, including a method of retrofitting an existing shipping rack to include the disclosed protective and support assemblies.

A wheel clamp includes a clamp body, a movable rod pivotally connected to the clamp body, a connecting rod fitted on the movable rod, and a rotating unit disposed in a lock core seat of the clamp body. The connecting rod has a threaded section for connecting with a screw. The rotating unit has a rotating rod to be inserted into an accommodating trough of the screw. A first engaging member is secured to the accommodating trough of the screw. A second engaging member is secured to the rotating rod of the rotating unit. The second engaging member has a second engaging block to mesh with and drive a first engaging block of the first engaging member so the connecting rod is able to be moved relative to the screw.

A chassis braking system for braking a chassis includes a braking unit including a braking surface biased toward a road surface on which the chassis runs and having a first state where movement of the braking surface toward the road surface is locked and a second state where the braking surface abuts against the road surface. A control unit releases the lock of the braking unit and shifts the braking unit from the first state to the second state when predetermined conditions are met.
