Abstract

Abstract A highly efficient motorcycle trailer apparatus having a generally u-shaped side member and an elongated guide member therebetween substantially supported by at least two opposing vertical members having hydraulic members integrally attached thereto is disclosed. The hydraulic members are operably coupled to the elongated guide member, centrally located therebetween two opposing sides of said u-shaped side member. A motor is operably joined to a hydraulic reservoir means coupled to a hydraulic line means of the hydraulic members to permit smooth raising and lowering of the elongated guide member for mounting or dismounting a motorcycle thereon.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 244 words
A motorcycle trailer apparatus, comprising, in combination: a motorcycle; a u-shaped side member means operably mounted over at least one tire means of said trailer apparatus, said u-shaped side member means comprising two laterally spaced, longitudinally extending members and a laterally extending cross member; an elongated guide member means centrally located therebetween said u-shaped side member means, said elongated guide member means being u-shaped with an elongated motorcycle supporting portion and two upwardly extending guiding portions for guiding and supporting said motorcycle thereon; wheel engaging means being vertically oriented and operably coupled to a front end portion of said elongated guide member means and having opposing outwardly extending flange means for laterally supporting a leading portion of a front tire of said motorcycle therebetween, said flange means being adjustable to accommodate motorcycle tires of different widths, said flange means also being of non-rigid character; two laterally extending side support member each integrally coupled to a respective side of said elongated guide member means two hydraulic cylinder means each operatively coupled between a side support member and a respective longitudinally extending member of said u-shaped side member means for raising and lowering said support member means and concurrently raising and lowering said guide member means, said raising and lower being accomplished while said guide member means remains substantially horizontally oriented; at least one hydraulic motor means for operating said two hydraulic cylinder means; and at least one battery means for operating said hydraulic motor means.
Claim 2
Dependent Claim 244 words
A motorcycle trailer apparatus, comprising, in combination: a motorcycle; a u-shaped side member means operably mounted over at least one tire means of said trailer apparatus, said u-shaped side member means comprising two laterally spaced, longitudinally extending members and a laterally extending cross member; an elongated guide member means centrally located therebetween said u-shaped side member means, said elongated guide member means being u-shaped with an elongated motorcycle supporting portion and two upwardly extending guiding portions for guiding and supporting said motorcycle thereon; wheel engaging means being vertically oriented and operably coupled to a front end portion of said elongated guide member means and having opposing outwardly extending flange means for laterally supporting a leading portion of a front tire of said motorcycle therebetween, said flange means being adjustable to accommodate motorcycle tires of different widths, said flange means also being of non-rigid character; two laterally extending side support member each integrally coupled to a respective side of said elongated guide member means two hydraulic cylinder means each operatively coupled between a side support member and a respective longitudinally extending member of said u-shaped side member means for raising and lowering said support member means and concurrently raising and lowering said guide member means, said raising and lower being accomplished while said guide member means remains substantially horizontally oriented; at least one hydraulic motor means for operating said two hydraulic cylinder means; and at least one battery means for operating said hydraulic motor means.
Claim 3
Dependent Claim 38 words
