Claim 1
Independent Claim
206 words
In combination with a rear carrier adapted to carry a child on a bicycle having a seat tube assembly and at least one strut member, said rear carrier being attached to tubular frame means having two ends, the improvement comprising: seat bracket means including a hook means and being pivotally adjustably attachable to said seat tube assembly; strut bracket means, said strut bracket means being selectively positionable along said strut member; yoke means including a yoke pin, formed at one end of said tubular frame means, said yoke means further including latch plate means pivotally mounted to said yoke pin; hand-tightenable yoke tensioning means, said tensioning means positioned at said yoke means opposite said yoke pin, said tensioning means adapted to hook to said seat bracket means; said latch plate means having slots formed therein to register with said tensioning means when said tensioning means is hooked to said seat bracket means and said latch plate means is pivoted thereupon, said tensioning means, when tightened, thereby compressibly maintaining said yoke means, said latch plate means, and said seat bracket means; and hand-tightenable fastener means positioned at said strut bracket means, whereby said second of said frame ends may be compressibly maintained at said strut bracket means.

In combination with a rear carrier adapted to carry a child on a bicycle having a seat tube assembly and at least one strut member, said rear carrier being attached to tubular frame means having two ends, the improvement comprising: seat bracket means including a hook means and being pivotally adjustably attachable to said seat tube assembly; strut bracket means, said strut bracket means being selectively positionable along said strut member; yoke means including a yoke pin, formed at one end of said tubular frame means, said yoke means further including latch plate means pivotally mounted to said yoke pin; hand-tightenable yoke tensioning means, said tensioning means positioned at said yoke means opposite said yoke pin, said tensioning means adapted to hook to said seat bracket means; said latch plate means having slots formed therein to register with said tensioning means when said tensioning means is hooked to said seat bracket means and said latch plate means is pivoted thereupon, said tensioning means, when tightened, thereby compressibly maintaining said yoke means, said latch plate means, and said seat bracket means; and hand-tightenable fastener means positioned at said strut bracket means, whereby said second of said frame ends may be compressibly maintained at said strut bracket means.
Claim 3
Dependent Claim
164 words
The apparatus as recited in claim 1 wherein: said rear carrier has formed along its bottom exterior surface a plurality of flat-bottomed gussets, each said gusset having formed therein an aperture extending through said rear carrier; attachment means for holding said rear carrier to said tubular frame means, said attachment means including a bolt dimensioned to pass through said gusset aperture, a strain relief nut, said strain relief nut having oppositely disposed faces, the first of said faces being flat, the second of said faces being concave, whereby said strain relief nut is threaded onto said bolt to abut said flat face against said flat-bottomed gusset, said concave face of said strain relief nut accommodating said tubular frame means; and nut means, said nut means being threadable onto said bolt means whereby said tubular frame means is compressed between said strain relief nut and said nut means, whereby the strain of tightening said nut means is thereby prevented from being transmitted to said gusset.
Claim 4
Dependent Claim
90 words
The apparatus as recited in claim 1 wherein said seat bracket means further comprises a base with a pair of legs depending therefrom in a generally U-shaped configuration, each said leg having an open-ended L-shaped slot formed therethrough which comprises said hook means, said slots oppositely disposed parallel one to another, said slots dimensioned to insertably accept said yoke tensioning means, said slots positioned whereby said open ends are closed off by said latch plate means when said latch plate means is pivoted to register with said yoke tensioning means.
