Claim 3

A stand as claimed in claim 1 wherein each of said clamping members is a bolt, and wherein each of said actuating means is threadably engaged with a respective one of said bolts.

Claim 4

A stand as claimed in claim 2 wherein each of said actuating means is a wing nut, and wherein said sleeves, said bolts and said wing nuts are so arranged that the enlarged head portion of said bolts and the respective wing nut associated therewith are disposed on opposite ends of the associated one of said sleeves.

Claim 5

A stand as claimed in claim 2 wherein the enlarged head portion of each said bolt is a T-head.

Claim 6

A stand as claimed in claim 1 wherein each of said abutment means further includes a resilient annular member disposed coaxially with respect to a respective one of said sleeveS, each of said clamping means extending through a respective one of said sleeves and through an associated one of said resilient annular members.

Claim 7

A stand as claimed in claim 5 and further including a plurality of substantially incompressible annular members disposed coaxially with respect to each of said sleeves whereby selected members of said plurality of annular members may be interposed between each of said sleeves and said resilient annular member associated therewith, thereby selectively to vary the spacing of said first clamping faces.

Claim 8

A stand as claimed in claim 1, wherein said roller supporting means are mounted on a pivotal mounting on said support frame for pivotal movement with respect thereto in a plane substantially parallel to said clamping faces.

Claim 9

A stand as claimed in claim 7 further including a first adjustment means for adjusting the spacing between said pivotal mounting of said roller support means on said support frame and said clamping members.

Claim 10

A stand as claimed in claim 8 further including a second adjustment means engageable with said roller supporting means and also engageable with a portion of the manually powered vehicle when it is supported by said stand, selectively to control the pivotal movement of said roller supporting means with respect to said support frame, and thereby selectively to control a force exerted by said roller on said driven wheel.

Claim 11

A stand for a manually powered vehicle comprising: a. a support frame assembly including a pair of spaced apart members, each in upstanding relation, and a pair of abutment means including respective transversely extending sleeves mounted on respective ones of said members and projecting towards one another from said members to provide respective first clamping faces in transversely spaced apart, face-to-face relation; b. a pair of clamping members extending along and within respective ones of said sleeves for sliding movement towards and away from one another in a direction transversely of said support frame, each said clamping member including an elongated stem portion terminating in an enlarged head portion having a substantially uninterrupted planar surface, and, on a surface opposite to said planar surface, and facing said stem, a second clamping face disposed in face-to-face relation with a respective one of said first clamping faces; c. a pair of actuating means drivingly engaging respective ones of said stems of said clamping members, each said actuating means engaging said frame for adjusting said clamping members transversely with respect to said frame, for clamping respective portions of a frame of a manually powered vehicle directly between respective ones of said first clamping faces and the associated said second clamping faces; d. a roller supporting means mounted on a pivotal mounting on said frame for pivotal movement with respect thereto in a plane substantially parallel to said clamping faces, and a roller mounted on said roller supporting means, for movement of said roller into and out of engagement with the driven wheel of a manually powered vehicle whose frame is clamped to said stand, said movement being in response to pivotal movement of said roller supporting means with respect to said support frame; e. a first adjustment means for adjusting the spacing between said pivotal mounting of said roller support means on said support frame and said clamping members; and f. second adjustment means engageable with said roller supporting means and also engageable with a portion of said manually powered vehicle when it is supported by said stand, selectively to control the pivotal movement of said roller supporting means with respect to said support frame, and thereby selectively to control the force inserted by said roller on said driven wheel, said second adjustment means including a lever having one end fixedly mounted on said roller supporting means and another end spaced from said one end in driven engagement with an adjustment rod.

Claim 12

A stand for a manually powered vehicle comprising: a. a support frame assembly including a pair of spaced apart members, each in upstanding relation, and a pair of abutment means including respective transversely extending sleeves mounted on respective ones of said members and projecting towards one another from said members to provide respective first clamping faces in transversely spaced apart, face-to-face relation; b. a pair of clamping members extending along and within respective ones of said sleeves for sliding movement towards and away from one another in a direction transversely of said support frame, each said clamping member including an elongated stem portion terminating in an enlarged head portion having a substantially uninterrupted planar surface, and, on a surface opposite to said planar surface, and facing said stem, a second clamping face disposed in face-to-face relation with a respective one of said first clamping faces; c. a pair of actuating means drivingly engaging respective ones of said stems of said clamping members, each said actuating means engaging said frame for adjusting said clamping members transversely with respect to said frame, for clamping respective portions of a frame of a manually powered vehicle directly between respective ones of said first clamping faces and the associated said second clamping faces; d. a roller supporting means mounted on a pivotal mounting on said frame for pivotal movement with respect thereto in a plane substantially parallel to said clamping faces, and a roller mounted on said roller supporting means, for movement of said roller into and out of engagement with the driven wheel of a manually powered vehicle whose frame is clamped to said stand, said movement being in response to pivotal movement of said roller supporting means with respect to said support frame; e. a first adjustment means for adjusting the spacing between said pivotal mounting of said roller support means on said support frame and said clamping members; and f. second adjustment means engageable with said roller supporting means and also engageable with a portion of said manually powered vehicle when it is supported by said stand, selectively to control the pivotal movement of said roller supporting means with respect to said support frame, and thereby selectively to control the force inserted by said roller on said driven wheel, said second adjustment means including a lever having one end fixedly mounted on said roller supporting means and another end spaced from said one end in driven engagement with an adjustment rod.

Claim 13

A stand as claimed in claim 10 wherein said adjustment rod is connectable to a portion of a manually powered vehicle when it is supported by said stand, and wherein said adjustment rod is threadedly engaged with said lever.
