Claim 9

A two wheel trailer comprising: a trailer body having a deck and side portions; a pair of vertically oriented trunnions located exteriorly of said side portions and mounted at their lower extremities, respectively, to the lower extremities of said side portions for pivotal movement about a pair of longitudinal pivot axes; a pair of elongated suspension arms mounted at their upper extremities, respectively, to the upper extremities of said trunnions for pivotal movement about transverse pivot axes; shock absorbing means carried by said side portions rearwardly of said suspension arms, respectively, and normally engageable with said suspension arms to resiliently limit the degree of rearward pivotal movement of said suspension arms about said transverse pivot axes; a pair of wheels located on said suspension arms and rotatably carried at the lower extremities of said suspension arms, respectively; and locking means normally preventing said pivotal movement of said trunnions about said longitudinal pivot axes, and selectively operable to permit said pivotal movement whereby said trunnions may be pivoted downwardly and inwardly of said side portions to permit location of said wheels inwardly of said side portions and beneath said deck.

Claim 10

A two wheel trailer according to claim 6 and including stops on said trunnions, respectively, limiting forward pivotal movement of said suspension arms about said transverse axes.

Claim 11

A two wheel trailer comprising: a trailer body having storage recesses and a pair of side portions; a pair of vertically oriented trunnions located exteriorly of said side portions and mounted at their lower extremities, respectively, to the lower extremities of said side portions for pivotal movement of said trunnions about a pair of longitudinal pivot axes; a pair of elongated suspension arms located exteriorly of said side portions and mounted at their upper extremities, respectively, to the upper extremities of said trunnions for pivotal movement of said suspension arms about transverse pivot axes; shock absorbing means carried by said side portions rearwardly of said suspension arms, respectively, and normally engageable with said suspension arms to resiliently limit the degree of rearward pivotal movement of said suspension arms about said transverse pivot axes; a pair of wheels located exteriorly of said suspension arms and rotatably carried at the lower extremities of said suspension arms, respectively; stops on said trunnions, respectively, engageable by said suspension arms to limit the degree of forward pivotal movement of said suspension arms about said transverse axes; and locking means normally preventing said pivotal movement of said trunnions about said longitudinal pivot axes, and selectively operable to permit said pivotal movement whereby said upper extremities of said trunnions may be pivoted downwardly and outwardly of said side portions to locate said wheels inwardly of said side portions and below said suspension arms, whereby said suspension arms may thereafter be pivoted rearwardly and outwardly, and whereby said suspension arms may thereafter be pivoted inwardly to located said trunnions, said suspension arms and said wheels inwardly of said side portions, with said wheels located upwardly of said suspension arms and within said storage recesses.
