7 Claims, 9 Drawing Figures DESCRIPTION OF THE INVENTION:
The present invention relates to a mobile collapsible ramp. More particularly, the invention relates to a mobile collapsible personal boat ramp.
The principal object of the invention is to provide a mobile collapsible ramp which is of simple structure and is inexpensive in manufacture, is collapsed and positioned for use with rapidity, facility, ease and convenience, is easily and conveniently transported, and is utilizable as a personal boat ramp or a ramp for any suitable type of vehicle under any suitable circumstances.
In order that the invention may be readily carried into effect, it will now be described with reference to the accompanying drawing, wherein:
FIG. 1 is a perspective view of an embodiment of the mobile invention in use position;
FIG. 2 is a view of a pair of chains of blocks affixed to each other lengthwise;
FIG. 3 is a per spective view of an end block of the mobile collapsible ramp of the invention;
FIG. 4 is an end view of a block of the mobile collapsible ramp of the invention;
FIGS. 5 and 6 are end views of another embodiment of a block of the mobile collapsible ramp of the invention;
FIG. 7 is a view of part of a block of the mobile collapsible ramp of the invention and another embodiment of a fastening ring affixable thereto;
FIG. 8 is an end view of still another embodiment of a block of the mobile collapsible ramp of the invention; and
FIG. 9 is an end view of yet another embodiment of a block of the mobile collapsible ramp of the invention.
The mobile collapsible ramp of the invention comprises a first plurality of blocks 1, 2, 3, 4, and so on (FIG. 1). Each of the blocks has a substantially resilient undersurface 5 (FIG. 4) and an upper surface 6, 7, 8, 9, and so on, respectively (FIG. 1), for accommodating a vehicle wheel (not shown in the FIGS).
The first plurality of blocks 1, 2, 3, 4 and so on, are coupled to each other in a chain (FIG. 1) by any suitable means such as, for example, a rope 10 (FIG. 1) passing through a bore 11 (FIG. 4) formed through each block.
The first plurality of blocks 1, 2, 3, 4 and so on, are remobably affixed to the ground by any suitable means such as, for example, a substantially vertical bore 12 (FIG. 1) through each block or a ring member 13 (FIGS. 1 and 3) or 14 (FIG. 7) affixed to each block and extending from a side thereof. A spike 15 (FIGS. 1 and 3) is adapted to pass through the vertical bore 12 or the ring member 13 or 14 into the ground.
Each of asecond plurality of blocks 16, 17, 18, and so on (FIG. 1), has a substantially resilient undersurface 5 (FIG. 4) and an upper surface 19, 20, 21, and so on, respectively (FIG. 1 for accommodating a vehicle wheel (not shown in the FIGS.)
The second plurality of blocks 16, 17, 18, and so on, are coupled to each other in a chain (FIG. 1) by any suitable means such as, for example, a rope 22 (FIG. 1) passing through a bore 11 (FIG. 4) formed through each block.
2 The second plurality of blocks 16, 17, 18 and so on,
are removably affixed to the ground by any suitable means such as, for example, a substantially vertical bore 23 (FIG. 1) through each block or a ring member 24 (FIG. 1) or 14 (FIG. 7) affixed to each block and extending from a side thereof. A spike 25 (FIG. 1) is adapted to pass through the vertical bore 23 or the ring member 24 or 14 into the ground.
The first and second plurality of blocks are fastened to the ground in spaced substantially parallel relation, as shown in FIG. 1.
The upper surface of each block may be concave, as shown in FIGS. 1, 3 and 4, or may be divided into separate surfaces, as shown in FIGS. 5, 6 and 9. In the embodiment of FIGS. 5 and 6, the separate surfaces 26 and 27, and 26 and 27 are on two different levels above the ground. In the embodiment of FIG. 9, each block has a median divider 28 projecting above the upper surface between the two surfaces 29 and 30.
In the embodiment of FIGS. 5 and 6, the wheels 31 and 32 of a trailer may be accommodated on the surfaces 26 and 26, and the wheels 33 and 34 of a towing vehicle may be accommodated on the surfaces 27 and 27'.
In the embodiment of FIG. 8, each of the undersurface 35 and the upper surface 36 is concave.
FIG. 2 shows two chains of blocks 37 and 38 affixed to each other lengthwise. A wedge 39 may be placed between the chains to level the depression formed by the sloped ends of the end blocks of said chains.
