CHOCK DEVICE FOR WHEELS Filed March 17, 1966 2 SheetsSheet 2 United States Patent Ofiice 3,353,633 CHOCK DEVICE FOR WHEELS Lawrence Leonard and Richard L. Leonard, both of 106 Holyoke St., Lynn, Mass. 01905 Filed Mar. 17, 1966, Ser. No. 535,106 2 Claims. (Cl. 188-32) This invention relates to a chock device for wheels such as automobile wheels.
One object of our invention is to provide a new chock device with sides that interlock in position of use so that pressure on one side, as wheel bears against it, more firmly interlocks said sides.
Another object is to provide a bottom for said device having a recessed portion to thereby provide a nest for two sides that are of such area that they will enter said recess, thereby making our device more compact when not in use. Said recessed portion also provides a better road grip in a soft or sandy surface.
Still another object is to provide the sides of our device with projecting members, spaced apart, against which a wheel being chocked can bear, and also provide recesses in said projecting members so that the main body of each side may make firm contact with the inner surfaces of the projecting members of the side opposite thereto.
A further object is to provide hinge members for said sides that are spaced apart and so positioned that the projecting members of one side are in alinement in an upward direction with the projecting members of the oppositely disposed sides, thereby assuring stability for our device.
A still further object is to provide such a device that is completely formed of parts that are relatively inexpensive to manufacture, can be easily assembled by unskilled labor, and can be used without special instructions.
The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrangement of parts such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and therefore, we are not to be limited to the construction disclosed by the drawings nor to the particular parts described in the specification; but are entitled to all such changes therefrom as fall within the scope of our claims.
In the drawings:
FIG. 1 is a top plan view of our chock device in position for use.
FIG. 2 is a side elevational view thereof.
FIG. 3 is an enlarged, sectional view taken on the line 33 of FIG. 1.
FIG. 4 is a side elevational view of our device in folded position, the bottom member being shown in the uppermost position.
FIG. 5 is a front elevational view of our device in position of use.
FIG. 6 is a side elevation view of our device in position of use, showing a wheel bearing against it.
As illustrated, our chock device for wheels has a bottom 10 having a recessed, intermediate portion 12 which, in position of use, is off the ground and provides a nesting portion later described. A hole 14 extends through the center thereof and at opposite sides are strengthening 3,353,633 Patented Nov. 21, 1967 ribs 16. At one side extremity of said bottom 10 are hollow hinge members or eyes 18 spaced apart, and at the opposite side extremity are similar hollow hinge members 18a spaced apart. These hinge members 18 and 18a, in position of use, are lower than said recessed portion 12, and are the foundation upon which our device rests in position of use.
A side or stop member 22 extends diagonally upwardly in position of use and it has projecting members 24 that are spaced apart, preferably being in alinement upwardly with said hollow, hinge members 18 to help our device achieve steadiness in position of use. Said side member projecting members 24 each has a recess 28 formed therein adjacent the free end, immediately beyond which are offset teeth 30 which a wheel W will contact when said side is in position of use. Hinge members 32 are at the bottom of said side member 22 being so spaced apart and of such a size that they fit into the spaces between said hinge members 18. A pintle 36 extends through said hinge members 18 and 32, movably holding them together as in the usual hinge. A hole 38 extends through said side member 22 and the latter is strengthened by ribs 40.
Another side or stop member 42 extends diagonally upright in position of use in a direction towards said side member 22. It has projecting members 44 that are spaced apart, preferably being in alinement upwardly with said hollow, hinge members 18a. Said projecting members 44 have recesses 48 formed therein adjacent their free ends, immediately beyond which are offset teeth 50 similar to said teeth 30. Hinge members 52 are at the bottom of said side member 42, being so spaced apart and of a size that they fit into the spaces between said hinge members 18a. A pintle 56 extends through said hinge members 52 and 18a, movably holding them together, and a hole 58 extends through said side 42 and the latter is strengthened by ribs 60. Said side members 22 and 42 are duplicates.
In position of use, said projecting members 24 extend between said projecting members 44, and the latter extend into the spaces between said projecting members 24. Thus said side members 22 and 42 bear against each other in use.
Our device is assembled by moving said sides 22 and 42 to diagonal positions pointing towards each other as shown in said FIG. 2. Said projecting members 24 enter the spaces between said projecting members 44, and the latter enter the spaces between said members 24, thus interlocking the two sides, with the main body of one side resting against the main body of the opposite side. To provide a firmer engagement, upper edge portions of said side 22 enter said recesses 48 and upper edge portions of said side 42 enter said recesses 28.
When our device is in folded position said holes 14, 38 and 58 are in alinement, consequently the three parts having said holes may be bolted together, or otherwise fastened.
What we claim is:
1. A chock device for wheels comprising a bottom, two sides and means movably connecting said sides to said bottom, each said side having a projecting member spaced laterally from each other and respectively extending diagonally upward in opposite directions in position of use and adapted to bear against the main body of the side opposite thereto when said sides, in position of bottom, each said side having a projecting member spaced 5 laterally from each other and respectively extending diagonally upward in opposite directions in position of use and adapted to bear against the main body of the side opposite thereto when said sides, in position of use, extending diagonally towards each other, one said projecting member having a recess therein extending laterally and spaced inwardly from the outside end thereof, the main body of one said side extending into said recess, each 4 outwardly and upwardly from and beyond said recess in position of use.
