Abstract

Abstract A wheeled trailer for transporting a boat which includes improved adjustable guide structure adjacent the rear end thereof for guiding a boat relative to the trailer during loading and unloading. The trailer comprises a chassis having laterally spaced longitudinal frame members extending along opposite sides thereof. The guide structure is defined by two generally upright posts adjustably secured to associated frame members so that each post may be selectively positioned at any location along the longitudinal extent of a frame member. The lateral spacing of the posts relative to each other may be selectively varied to accommodate boat hulls of various widths therebetween. Each guide post is formed with a generally L-shaped lower end which is releasably secured to an associated frame member so that the posts are rotatable about the axes of their lower ends whereby the lateral spacing of the upper ends of the posts may be varied. Means also are provided to selectively incline the posts relative to the vertical so that boats having hulls of varying contours also may be accommodated.

Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 193 words
Adjustable guide structure for a boat trailer which includes a chassis having laterally spaced frame members extending longitudinally thereof, said guide structure comprising A. a pair of laterally spaced opposed generally upright guide posts positioned adjacent the rear end of said trailer, and B. means mounting each of said guide posts on an associated frame member, comprising 1. mounting structure adjustably securing each said post to its associated frame member so that the lateral spacing of said posts relative to each other may be selectively varied in accordance with the width and contour of the hull of the boat to be carried on said trailer, said mounting structure comprising a. a mounting plate engaged with one side of said associated frame member, b. a pair of U-bolt and nut fasteners traversing said associated frame member and passing through said mounting plate, c. an end portion of said post being positioned through said U-bolts and held thereby against the opposite side of said frAme member, and d. a shim member interposed between said side of said frame member and said post end whereby the axis of said post is inclined relative to the vertical.
Claim 2
Dependent Claim 193 words
Adjustable guide structure for a boat trailer which includes a chassis having laterally spaced frame members extending longitudinally thereof, said guide structure comprising A. a pair of laterally spaced opposed generally upright guide posts positioned adjacent the rear end of said trailer, and B. means mounting each of said guide posts on an associated frame member, comprising 1. mounting structure adjustably securing each said post to its associated frame member so that the lateral spacing of said posts relative to each other may be selectively varied in accordance with the width and contour of the hull of the boat to be carried on said trailer, said mounting structure comprising a. a mounting plate engaged with one side of said associated frame member, b. a pair of U-bolt and nut fasteners traversing said associated frame member and passing through said mounting plate, c. an end portion of said post being positioned through said U-bolts and held thereby against the opposite side of said frAme member, and d. a shim member interposed between said side of said frame member and said post end whereby the axis of said post is inclined relative to the vertical.
Claim 3
Dependent Claim 42 words
Adjustable guide structure for a boat trailer which includes a chassis having laterally spaced frame members extending longitudinally thereof, said guide structure comprising A. a pair of laterally spaced opposed generally upright guide posts positioned adjacent the rear end of said trailer,
Claim 4
Dependent Claim 42 words
Adjustable guide structure for a boat trailer which includes a chassis having laterally spaced frame members extending longitudinally thereof, said guide structure comprising A. a pair of laterally spaced opposed generally upright guide posts positioned adjacent the rear end of said trailer,
Claim 5
Dependent Claim 56 words
means mounting each of said guide posts on an associated frame member for selective adjustable rotation about the axis of said post lower end, comprising a. mounting structure defined by U-shaped fasteners secured to said associated frame member, b. said post lower end passing through said fasteners and being held against said associated frame member thereby,
Claim 6
Dependent Claim 56 words
means mounting each of said guide posts on an associated frame member for selective adjustable rotation about the axis of said post lower end, comprising a. mounting structure defined by U-shaped fasteners secured to said associated frame member, b. said post lower end passing through said fasteners and being held against said associated frame member thereby,
Claim 7
Dependent Claim 66 words
said post lower end passing through said fasteners and being held against said associated frame member thereby, C. each said post being adjustably rotatable in said fasteners relative to its associated frame member so that the lateral spacing of said posts relative to each other may be selectively varied in accordance with the width of the hull of the boat to be carried on said trailer.
Claim 8
Dependent Claim 66 words
said post lower end passing through said fasteners and being held against said associated frame member thereby, C. each said post being adjustably rotatable in said fasteners relative to its associated frame member so that the lateral spacing of said posts relative to each other may be selectively varied in accordance with the width of the hull of the boat to be carried on said trailer.
Claim 9
Dependent Claim 14 words
a shim member interposed between said post lower end and said associated frame member,
Claim 10
Dependent Claim 14 words
a shim member interposed between said post lower end and said associated frame member,
Claim 11
Dependent Claim 13 words
The guide structure of claim 2 in which said mounting means further includes
Claim 12
Dependent Claim 45 words
each said post being adjustably rotatable relative to its associated frame member so that the lateral spacing of said posts relative to each other may be selectively varied in accordance with the width of the hull of the boat to be carried on said trailer.
Claim 13
Dependent Claim 45 words
each said post being adjustably rotatable relative to its associated frame member so that the lateral spacing of said posts relative to each other may be selectively varied in accordance with the width of the hull of the boat to be carried on said trailer.
Claim 14
Dependent Claim 14 words
a shim member interposed between said post lower end and said associated frame member,
Claim 15
Dependent Claim 14 words
a shim member interposed between said post lower end and said associated frame member,
Claim 16
Dependent Claim 21 words
said shim causing the upper end of said post to extend at a predetermined angle of inclination relative to the vertical.
Claim 17
Dependent Claim 21 words
said shim causing the upper end of said post to extend at a predetermined angle of inclination relative to the vertical.
Claim 18
Dependent Claim 42 words
The guide structure of claim 2 in which said U-shaped fasteners adjustably secure said post to said associated frame member so that the orientation of such post relative to said trailer rear end may be selectively varied longitudinally along such frame member.
