Abstract

Abstract A hand operated cycle apparatus including a cycle frame having a pair of spaced apart rear wheels rotatably attached along the horizontal axis to the rear of the cycle frame. A yoke is pivotally attached to the front of the cycle frame and a front wheel is rotatably attached to the yoke. A drive mechanism is provided for rotating the front wheel and pedals are attached to an upper portion of the yoke and to the drive apparatus for selectively turning the drive apparatus by hand. A seat is attached to a rear portion of the cycle frame. Brakes are operably attached to the cycle frame for selectively holding both of the rear wheels from rotating with respect to the frame. A footrest is provided for supporting the feet of the cycle user. A wheelchair hitch is connected to the rear of the cycle frame and has an elongated rod extending transverse to the direction of forward movement of the cycle frame and has a pair of spaced locking members thereon so that a wheelchair having foot supports on the front thereof can be easily towed from place to place without the fear of it coming loose, while at the same time being easily attached to or detached from the hitch.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 240 words
A hand operated cycle apparatus comprising: a cycle frame; a pair of spaced apart rear wheels rotatably attached along a horizontal axis to the rear of the cycle frame; a yoke pivotally attached to the front of the cycle frame; a front wheel rotatably attached to said yoke; drive means for selectively rotating said front wheel; pedal means attached to an upper portion of said yoke and to said drive means for selectively turning said drive means by hand; a seat operably attached to a rear portion of said cycle frame; brake means operably attached to said cycle frame for selectively holding each of the rear wheels form rotating with respect to the frame; footrest means for supporting the feet of a cycle user; a wheelchair having wheelchair frame and a seat, a pair of rear wheels, a pair of front wheels and footrests connected to said wheelchair frame; a wheelchair hitch connected to the rear of said cycle frame, said hitch comprising a somewhat horizontally disposed rod extending transverse to the direction of forward movement of said cycle frame and a pair of spaced apart locking members connected at one end to said rod and extending in the direction of forward movement of said cycle frame whereby the footrests of said wheelchair can be placed below said locking members to prevent the wheelchair from being dislodged from said hitch when said wheelchair is being towed behind said cycle frame.
Claim 2
Dependent Claim 240 words
A hand operated cycle apparatus comprising: a cycle frame; a pair of spaced apart rear wheels rotatably attached along a horizontal axis to the rear of the cycle frame; a yoke pivotally attached to the front of the cycle frame; a front wheel rotatably attached to said yoke; drive means for selectively rotating said front wheel; pedal means attached to an upper portion of said yoke and to said drive means for selectively turning said drive means by hand; a seat operably attached to a rear portion of said cycle frame; brake means operably attached to said cycle frame for selectively holding each of the rear wheels form rotating with respect to the frame; footrest means for supporting the feet of a cycle user; a wheelchair having wheelchair frame and a seat, a pair of rear wheels, a pair of front wheels and footrests connected to said wheelchair frame; a wheelchair hitch connected to the rear of said cycle frame, said hitch comprising a somewhat horizontally disposed rod extending transverse to the direction of forward movement of said cycle frame and a pair of spaced apart locking members connected at one end to said rod and extending in the direction of forward movement of said cycle frame whereby the footrests of said wheelchair can be placed below said locking members to prevent the wheelchair from being dislodged from said hitch when said wheelchair is being towed behind said cycle frame.
Claim 3
Dependent Claim 45 words
The apparatus of claim 1 wherein: said rod of the hitch is part of a continuous loop; and means for pivotally attaching said loop to said frame along a vertical axis whereby said hitch can be pivoted between an operative position and a stored position.
Claim 4
Dependent Claim 20 words
The apparatus of claim 1 including means connected to the cycle frame for adjusting the position of the footrest means.
Claim 5
Dependent Claim 98 words
The apparatus of claim 3 wherein said footrest adjusting means comprises: a horizontal bar connected to said frame; clamp means for frictionally gripping said bar; threaded fastener means connecting the footrest means to the clamp means whereby when the threaded fastener means is loosened, the footrest means can be adjustably pivoted about a horizontal axis and can be adjustably slid along the bar and once the footrest means is in a desired position, the threaded fastener means can be tightened down to frictionally hold the footrest means in place with respect to the clamp means and the bar.
Claim 6
Dependent Claim 19 words
The apparatus of claim 4 including luggage rack means attached to said frame below said seat for storing cargo.
