Claim 1
Independent Claim
311 words
For converting a conventional bicycle of the type having a frame including a drive hub from which a rear wheel supporting fork extends rearwardly and a diagonal brace extends forwardly to a steering post for the front wheel supporting fork, a stand for supporting such a bicycle and a person seated thereon comprising: (1) a main body including a pair of members each having a fore portion adapted to be disposed in parallel relation with each other and an aft portion adapted to extend rearwardly therefrom at an obtuse angle relative to its respective fore portion; (2) means for securing the fore portions of said pair of members in spaced parallel relation to provide a guideway therebetween and a Y-shaped frame in which the angularly disposed aft portions extend rearwardly therefrom as a pair of diverging leg members having foot ends; (3) a hook shaped member secured to the fore ends of the fore portions of said pair of members above the parallel plane thereof for engaging the diagonal brace of a bicycle; (4) a hub support mounted on the spaced parallel fore portions of said members for engaging and supporting the drive hub of a bicycle; and (5) securing means on said hub support extending into the guideway between the spaced parallel fore portions of said pair of members for releasably securing the hub support along the length thereof and in engagement with the drive hub of a bicycle to dispose the Y-shaped frame in a position in which the foot ends of each said diverging aft portions of said pair of members are disposed in spaced relation beneath the rear wheel supporting fork of a bicycle cooperating with the front wheel of such bicycle to support the latter tripod fashion with the rear wheel of such bicycle elevated for free turning operation by a person seated on the bicycle.

For converting a conventional bicycle of the type having a frame including a drive hub from which a rear wheel supporting fork extends rearwardly and a diagonal brace extends forwardly to a steering post for the front wheel supporting fork, a stand for supporting such a bicycle and a person seated thereon comprising: (1) a main body including a pair of members each having a fore portion adapted to be disposed in parallel relation with each other and an aft portion adapted to extend rearwardly therefrom at an obtuse angle relative to its respective fore portion; (2) means for securing the fore portions of said pair of members in spaced parallel relation to provide a guideway therebetween and a Y-shaped frame in which the angularly disposed aft portions extend rearwardly therefrom as a pair of diverging leg members having foot ends; (3) a hook shaped member secured to the fore ends of the fore portions of said pair of members above the parallel plane thereof for engaging the diagonal brace of a bicycle; (4) a hub support mounted on the spaced parallel fore portions of said members for engaging and supporting the drive hub of a bicycle; and (5) securing means on said hub support extending into the guideway between the spaced parallel fore portions of said pair of members for releasably securing the hub support along the length thereof and in engagement with the drive hub of a bicycle to dispose the Y-shaped frame in a position in which the foot ends of each said diverging aft portions of said pair of members are disposed in spaced relation beneath the rear wheel supporting fork of a bicycle cooperating with the front wheel of such bicycle to support the latter tripod fashion with the rear wheel of such bicycle elevated for free turning operation by a person seated on the bicycle.
Claim 3
Dependent Claim
104 words
The stand in accordance with claim 1 in which said hub support comprises: (1) an angle clip having one lower flange adapted to rest upon the fore portions of said pair of members lengthwise across said guideway therebetween and having its other flange extending upwardly therefrom for tangent engagement with the drive hub of a bicycle; (2) a threaded bolt having one end secured to the bottom of said lower flange for extending into and through said guideway; and (3) a means including threaded wing nut on the exposed end of said bolt for clampingly securing said angle clip to said pair of members.
Claim 4
Dependent Claim
65 words
The stand in accordance with claim 2 including a guide pin secured to the bottom of the lower flange of said angle clip in spaced relation to said bolt thereon on a plane transverse to the length of said angle clip for extension into said guideway and cooperating with said bolt for maintaining said angle clip in hub supporting position upon said pair of members.
Claim 5
Dependent Claim
36 words
The stand in accordance with claim 3 in which said diverging leg members are bowed upwardly at a slight angle at their point of convergence and relative to the parallel portions of said pair of members.
Claim 6
Dependent Claim
91 words
The stand in accordance with claim 2 including a tensioned roller comprising: (1) a U-shaped clevice having its web portion adapted to rest upon the spaced parallel fore portions of said pair of members; (2) a tensioned roller mounted on said clevice for turning about an axis transverse to said guideway and tread engagement with the rear wheel of the bicycle supported on said stand; and (3) means extending downwardly from said clevice into said guideway for securing the clevice and tensioned roller to the fore portions of said pair members.
Claim 7
Dependent Claim
44 words
The stand in accordance with claim 5 including a strut member secured to said pair of members adjacent the zone of convergence of said leg members therefrom for resisting flexing of the latter due to excessive weight of a person seated on said bicycle.
Claim 8
Dependent Claim
104 words
The stand in accordance with claim 6 in which said strut is a threaded jack screw, a threaded base on the lower end of said jack screw; a coupling plate pivotally connected to the upper end of said jack screw and adapted to extend upwardly into and through the guideway between said pair of members; and pin means extending laterally from each side of said coupling plate both above and below said pair of members for bindingly engageing the same due to the diagonal disposition of the latter against the pivotal connection of said coupling plate with the upper end of said jack screw.
Claim 9
Dependent Claim
44 words
The stand in accordance with claim 1 including a means extending between the extreme end of each of said diverging leg members and the rear fork of the bicycle and connected thereto for stabilizing the latter during operation thereof by a person seated thereon.
Claim 10
Dependent Claim
49 words
The stand in accordance with claim 8 in which said diverging leg members each have a loop secured thereto above their respective tripod foot ends for receiving said means extending between the latter and the rear fork for connection to said means for stabilizing the bicycle during operation thereof.
Claim 11
Dependent Claim
81 words
The stand in accordance with claim 9 in which said means connected to the loop on the end of each leg member comprises a belt having one end secured thereto and its opposite end adapted to extend over and around the respective tine of the rear fork; and a snubber buckle on said strap for said opposite end of said strap for tightening the strap securely between the bicycle frame and the loop on the end of the respective leg member.
