Abstract

Abstract A device for pedaling a bicycle in a stationary state, for the purpose of physical training or bicycle testing. This device, a kind of bicycle stand, comprises a member for unmovably holding a front wheel of a bicycle and the other member for sustaining a pair of rollers on which a rear wheel of the bicycle is rotatably placed, said members being formed at or connected to both longitudinal ends respectively of a strip of plate, and a bicycle supporting frame extending vertically aslant in connection with the above-mentioned strip of plate, in the foregoing construction this device enabling a bicycle to be pedaled in a stationary state on this device and accordingly enabling the attainment of a physical training without going outdoors. This device also serves for stationary testing a bicycle for its running and/or braking efficiency. The length and height of the above-mentioned strip of plate and bicycle supporting frame respectively and further the distance between the pair of rollers may be changed predeterminedly so as to adjust to the length and height of the bicycle and diametrical size of its rear wheel, and further a load may be imposed on the bicycle pedaling by applying any suitable friction to the rotation of said rollers so as to add to the physical training effect.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 235 words
A bicycle stand and training roller, which comprises a bicycle wheel supporting body which comprises a base plate strip and two side-walled, elongate bicycle wheel-supporting members each fixed to said base plate by rivets at each of the longitudinal ends thereof, one member for holding the front wheel stationarily and the other member incorporating rollers so as to support the rear wheel rotatably on said rollers, and a frame for uprightly sustaining the bicycle which comprises a strip of plate having holes at each of the logitudinal ends thereof and being pivotally fitted by one of said rivets in a horizontally-semicircularly rotatable state at its intermediate portion to the joint of the base plate and the front wheel-holding member, and two pipes extending from the ground through said holes upwardly in their mutually-approaching directions, two elongate bolts being inserted in said pipes respectively at their upper ends, the length of the inserted portion of said bolts being adjustable by wing nuts fitted one each around said bolts, said bolts at their upper ends joining each other by the medium of a hook of a mountainlike form with its summit being centrally recessed downwardly and the lower ends of its sloping portions connecting to upper ends of said bolts by screws, said downwardly recessed portion being adapted to accept a bicycle at the point where the fork joins the front of the frame of said bicycle.
Claim 2
Dependent Claim 235 words
A bicycle stand and training roller, which comprises a bicycle wheel supporting body which comprises a base plate strip and two side-walled, elongate bicycle wheel-supporting members each fixed to said base plate by rivets at each of the longitudinal ends thereof, one member for holding the front wheel stationarily and the other member incorporating rollers so as to support the rear wheel rotatably on said rollers, and a frame for uprightly sustaining the bicycle which comprises a strip of plate having holes at each of the logitudinal ends thereof and being pivotally fitted by one of said rivets in a horizontally-semicircularly rotatable state at its intermediate portion to the joint of the base plate and the front wheel-holding member, and two pipes extending from the ground through said holes upwardly in their mutually-approaching directions, two elongate bolts being inserted in said pipes respectively at their upper ends, the length of the inserted portion of said bolts being adjustable by wing nuts fitted one each around said bolts, said bolts at their upper ends joining each other by the medium of a hook of a mountainlike form with its summit being centrally recessed downwardly and the lower ends of its sloping portions connecting to upper ends of said bolts by screws, said downwardly recessed portion being adapted to accept a bicycle at the point where the fork joins the front of the frame of said bicycle.
Claim 3
Dependent Claim 35 words
a bicycle stand as claimed in claim 1, in which the base plate consists of two strips of plate connected detachably to each other at one or more than one points by bolts and nuts.
Claim 4
Dependent Claim 73 words
A bicycle stand as claimed in claim 1, in which the front wheel holding member is elongated in the longitudinal direction of said base plate, said member consisting of side plates and a bottom plate, said side plates being erected from sidewise ends of said bottom plate thereby forming an upwardly-open longitudinal groove also open at both ends, the width of said groove being slightly bigger than the thickness of the front wheel.
