A support rack for camper bodies and the like comprising a pair of spaced ground engaging base members; at least one upstanding post pivotally connected to each said ground engaging base member and extending upwardly to be at an elevation slightly above the overhang bottoms of a camper body mounted on a truck when said post is upright; a camper body engaging means pivotally connected at the top of each of said upstanding posts; means for maintaining said camper body engaging means substantially parallel to said base members during pivoting of said posts to a position below the elevation of the overhang bottoms; means for locking each said post in a generally upright position; means for holding the camper body engaging means against the overhanging bottoms of a camper body mounted on a truck; and means for resiliently holding the camper body engaging means against the overhang bottoms of a camper body mounted on a truck and positioned between the upstanding posts respectively fixed to the pair of spaced ground engaging members.
Claim 4
Dependent Claim
172 words
A support rack for camper bodies and the like comprising a pair of spaced ground engaging base members; at least one upstanding post pivotally connected to each said ground engaging base member and extending upwardly to be at an elevation slightly above the overhang bottoms of a camper body mounted on a truck when said post is upright; a camper body engaging means pivotally connected at the top of each of said upstanding posts; means for maintaining said camper body engaging means substantially parallel to said base members during pivoting of said posts to a position below the elevation of the overhang bottoms; means for locking each said post in a generally upright position; means for holding the camper body engaging means against the overhanging bottoms of a camper body mounted on a truck; and means for resiliently holding the camper body engaging means against the overhang bottoms of a camper body mounted on a truck and positioned between the upstanding posts respectively fixed to the pair of spaced ground engaging members.
Claim 5
Dependent Claim
39 words
A support rack as in claim 1, wherein said means for resiliently holding the camper body engaging means against the overhang bottoms of a camper body also limits rotation of each upstanding post with respect to its base member.
Claim 6
Dependent Claim
73 words
A support rack as in claim 1, wherein the pair of spaced ground engaging members comprise parallel elongate members of equal length and wherein the at least one upstanding post comprises parallel posts pivotally connected for parallel movement to each end of the parallel members and further including a rear connecting member connected between one rear end of one said parallel member and the adjacent rear end of the other said parallel member.
Claim 7
Dependent Claim
48 words
A support rack as in claim 3, wherein the camper body engaging means compriseS rails pivotally connected between the tops of the upstanding posts on front and rear ends of each parallel member, whereby said rails and said posts form upstanding parallelogram frameworks with their associated parallel members.
Claim 8
Dependent Claim
157 words
A support rack as in claim 4, wherein the means for locking each post in its generally upright position includes chains extending tautly across each of the frameworks from points adjacent to the lower ends of the posts at the fronts of the parallel members to points adjacent to the upper ends of the posts at the rear of the parallel members, when the posts are in their generally upright positions; and releasable chain means extending across each of the frameworks from points adjacent to the lower ends of the posts at the rear of the parallel members to points adjacent to the upper ends of the posts at the front of the parallel members, said releasable chain means including adjustment means for tightening said chain means to be taut when the posts are in their generally upright condition and for releasing said chain means whereby said posts can pivot forwardly with respect to said parallel members.
Claim 9
Dependent Claim
26 words
A support rack as in claim 4, wherein the chain means each includes spring means limiting rotation of the posts when the chain means is released.
