ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a wheel chock for retaining a cycle for transportation on a vehicle and more particularly to such a device which is removably mounted on a track on the floor of the transporting vehicle.
2. Description of the Related Art
Chocks are commonly employed to support cycles such as motorcycles for transportation on a vehicle such an aircraft or A truck. A typical such device is described in U.S. Pat. No. 3,785,517 issued Jan. 15, 1974 to Brajkovich. Such prior art devices while effective in retaining the cycle in position during transportation tend to be overly expensive in their construction. Further, they cannot as readily be removed and reinstalled as to be desired. This factor is of particular importance in aircraft transportation where the goods being transported varies from day to day and the compartment must be modified as need be to handle each type of goods. The device of the present invention overcomes these shortcoming by providing a device of simple and economical construction which can rapidly and easily be installed and removed from a transportation compartment.
SUMMARY OF THE INVENTION
The device of the present invention is formed from a bar which is bent into a formation which includes a pair of opposing bottom arms which form a base and a first pair of opposing side arms spaced above the bottom arms which run slightly upturned from the bottom arms. Extending upwardly from the first pair of side arms are a second pair of opposing side arms, the top ends of the second pair of side arms being joined together by a cross arm forming a top piece.
A substantially flat base plate is fixedly attached to the bottom arms. The base plate has a pair of longitudinally spaced studs attached thereto, these studs fitting into a receptacles in a track installed on the floor of the transportation compartment. A spring loaded plunger is located between the two studs, this plunger being driven by the spring into a receptacle in the track. With the studs and the plunger installed in the track, the chock is held firmly to the vehicle floor. The chock can be released from the track merely by pulling upwardly on the plunger and sliding the chock longitudinally and lifting upwardly.
It is therefore an object of this invention to provide an improved chock for retaining a cycle in place for transportation on a vehicle;
It is a further object of this invention to provide a chock for use in retaining a cycle in place for transportation on a vehicle which can more readily and rapidly be installed in and removed from such vehicle;
Other objects of the invention will become apparent as the description proceeds in connection with the accompanying drawings.
