Abstract
Abstract An adjustable motorcycle passenger floorboard is attached at either side of a motorcycle frame below the rear seat. The device has a cylindrical rail having a brace at either end. The braces have slotted bolt holes for allowing the device to be bolted to the frame. A split clamp is attached around the cylindrical rail. The clamp, when loosened, can be slid between the braces of the cylindrical rail for allowing a continuous adjustment of the floorboard. The floorboard is attached to the clamp by a bar which can be rotated about its axis in a notched recess in the clamp for adjusting the attitude of the floorboard relative to the motorcycle. There are two adjustments in the device; one for adjusting the floorboard in a fore and aft position relative to the frame, and the other for adjusting the attitude or rake of the floorboard relative to the frame.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
An adjustable passenger floorboard in combination with a motorcycle comprising: cylindrically shaped rail support means attached at its ends to the frame of a motorcycle and used for supporting said floorboard; split clamp means extending from said floorboard and attached around and slidable on said rail support means for allowing a continuous adjustment of said floorboard along the track between said ends of said rail support means; said clamp means includes a rectangular bar pivotally attached at one end to said floorboard and at its other end to said clamp means, said bar positioned in a notched recess in said clamp means for allowing said bar to be rotated about its axis to any of said notches for adjusting the attitude of said floorboard relative to said motorcycle frame; pivotal means between said floorboard and said clamping means for allowing said floorboard to be folded; stop means on the bottom of said floorboard for preventing the floorboard from pivoting below said bar whereby adjusting the attitude of said floorboard is accomplished by axially moving said rectangular bar and reinserting said rectangular bar in another notched recess.
Claim 2
Dependent Claim
186 words
An adjustable passenger floorboard in combination with a motorcycle comprising: cylindrically shaped rail support means attached at its ends to the frame of a motorcycle and used for supporting said floorboard; split clamp means extending from said floorboard and attached around and slidable on said rail support means for allowing a continuous adjustment of said floorboard along the track between said ends of said rail support means; said clamp means includes a rectangular bar pivotally attached at one end to said floorboard and at its other end to said clamp means, said bar positioned in a notched recess in said clamp means for allowing said bar to be rotated about its axis to any of said notches for adjusting the attitude of said floorboard relative to said motorcycle frame; pivotal means between said floorboard and said clamping means for allowing said floorboard to be folded; stop means on the bottom of said floorboard for preventing the floorboard from pivoting below said bar whereby adjusting the attitude of said floorboard is accomplished by axially moving said rectangular bar and reinserting said rectangular bar in another notched recess.
Claim 3
Dependent Claim
228 words
An adjustable passenger floorboard in combination with a motorcycle comprising: cylindrically shaped rail support means attached at its ends to the frame of a motorcycle and used for supporting said floorboard; split clamp means extending from said floorboard and attached around and slidable on said rail support means for allowing a continuous adjustment of said floorboard along the track between said ends of said rail support means; said clamp means includes a rectangular bar pivotally attached at one end to said floorboard and its other end to said clamp means, said bar positioned in a notched recess in said clamp means for allowing said bar to be rotated about its axis to any of said notches for adjusting the attitude of said floorboard relative to said motorcycle frame; pivotal means between said floorboard and said clamping means for allowing said floorboard to be folded; stop means on the bottom of said floorboard for preventing the floorboard from pivoting below said bar; brace means attached at both ends of said rail support means, said brace means having a slotted bolt hole for allowing attachment to a multiplicity of various types of motorcycle bolt hole patterns, or for adjusting the rake of said rail support means whereby adjusting the attitude of said floorboard is accomplished by axially moving said rectangular bar and reinserting said rectangular bar in another notched recess.
