Bicycle training and exercise device

A bicycle rider training device also adapted for use as an exerciser for walkers or joggers comprising a low elevation level base, a level moving beltway on the base extending lengthwise of the base for a major portion of the length of the base, said beltway comprising an endless belt having a top run substantially flush with the top of the base, a series of spaced transverse axis support rollers for said upper run preventing it from sagging, a pair of forward and rear guide rolls engaging opposite ends of the endless belt, power means to drive the rear drive roll in a direction causing movement of the top run of the belt toward the rear of said base, a transverse axis idler roll on the base near its rear end and spaced rearwardly of and being substantially at the elevation of the rear guide roll for the endless belt, whereby the rear wheel of a conventional bicycle may be cradled on the idler roll and the rear of the endless belt as it passes around said rear guide roll for the belt, forward and rear pairs of laterally spaced parallel horizontal longitudinal axis bicycle wheel restraint rollers mounted on said base, said wheel restraint rollers all being at one elevation slightly above the level of the top of the base and top run of the endless belt, the rollers of each pair being disposed adjacent to and parallel to the opposite longitudinal edges of the belt to prevent the wheels of a bicycle from leaving the lateral confines of the belt, the rear pair of wheel restraint rollers being disposed immediately above the rear guide roll for the belt and said rear idler roll, the lengths of the wheel restraint rollers in said pairs and the longitudinal spacing of said pairs enabling all sizes of conventional bicycles to have their front and rear wheels placed between the forward and rear pairs of restraint rollers, an upright inverted U-shaped substantially rigid frame including side vertical bars and a top transverse bar disposed substantially midway between the rear idler roll and the rear guide roll for said belt, said substantially vertical bars being anchored to said base at points spaced laterally outwardly of the side longitudinal edges of the endless belt, said top transverse bar being at a sufficient elevation above the base to form a convenient hand grip for a walker or jogger whose feet are placed on the top run of said belt, a pair of comparatively short horizontal longitudinal arms on the vertical bars projecting forwardly thereof, coupling carrying said arms and being adjustable and lockable at desired elevations on the vertical bars so that the heights of said arms may be varied, a clamp plate adapted for attachment removably to the frame of a bicycle near and below the seat thereof, and a pair of equal length flexible substantially non-stretchable restraint elements connected between opposite ends of said clamp plate and said adjustable arms, whereby lateral tilting of a bicycle is restrained within safe limits during use of the device.
