EXERCISING DEVICE Filed Aug. 16, 1960 INVENTOR.
Philip Sreller ATTORNEY Sttes York Filed Aug. 16, 196i), Ser. No. 49,880 9 Claims. (Cl. 27273) This invention relates to exercising devices, and more particularly, concerns exercising devices, of the bicycle type.
It has been proposed to provide exercising devices wherein a pedal operated portion thereof may be braked to offer regulated resistance to the pedalling effort of the user of the device. In such devices, the exercising action is necessarily limited to the lower body portions of the user, including the legs, thighs and hips, while the upper portions of the body do not benefit from the exercising action.
Accordingly, an object of this'invention is to provide an improved exercising device of the bicycle type, wherein means is provided for concurrently exercising the upper and lower body portions of the user.
Another object of this invention is to provide a device of the character described, wherein the handle bars are adapted to be reciprocated by the user so as to exercise the arms and shoulders, while pedalling to exercise the lower body portions, the pedalling action being correlated to the movement of the handle bars whereby the operation of one in effect regulates the operation of the other.
Yet another object of this invention is to provide a bicycle type exerciser of simple construction and minimum number of components parts to materially reduce the manufacturing costs thereof, yet being effective to provide close regulation of the exercising action of the device, by the user.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
In the drawing, FIG. 1 is a perspective view of an exercising device embodying the invention;
FIG. 2 is a side elevational view thereof showing the reciprocatory handle bar in its forward position; and
FIG. 3 is a view similar to that of FIG. 2, showing the handle bar in its retracted position.-
Essentially the exercising device of the instant invention comprises a bicycle frame arranged for stationary disposition on a supporting surface while in use. The frame has the usual seating means for the user and a handle bar assembly arranged for reciprocatory move ment towards and away from the seating means. Pedal means is mounted on the frame and braking means is provided for adjusting the resistance to be offered to the pedalling action, together with a connection between the braking means and the reciprocatory handle bar assembly to allow the user to control the braking means.
Thus, as shown in FIG. 1, designates an exercising device embodying the invention. The same takes the form generally of a bicycle frame formed of tubular metal parts, including a rearwardly disposed, upstanding seat supporting portion 12, a forwardly disposed upstanding handle bar portion 13 and a generally horizontally disposed pedal assembly mounting portion 14 which interconnects the seat supporting portion 12 and the handle bar supporting portion 13 at the lower ends thereof.
A horizontally disposed reinforcing bar 15 extends forwardly from a lower portion of seat supporting portion 12 to a forward portion of the pedal assembly 14. A conventional seat member 16 is adjustably mounted on the upper end of seat supporting portion 12. Frame 11 is supported on a suitable supporting surface such as a floor or the like, by a pair of downwardly divergent 3,024,023 Patented Mar. 6, 1962 P l C legs 17 which are aflixed at their upper ends to a split bracket 18, which in turn is secured to seat supporting frame portion 12.
A second pair of downwardly divergent legs 19 are secured at their upper ends to the upper end of handle bar supporting frame portion 13 by cross pins 20. A pedal assembly, generally indicated at 21, is mounted on frame portion 14. Assembly 21 includes a bearing bracket 22 secured at the juncture of seat supporting frame portion 12 and frame portion 14. A pedal crank shaft 23 is rotatably mounted on hearing bracket 22, with crank arms 24 extending from the crank shaft 23. The usual pedals 25 are mounted on the extremities of crank arms 24. v
Means is provided for braking the pedal assembly 21 in the form of-a braking disc 26 having an elliptical outline edge 27 and eccentrically affixed to crank shaft 23. Disc 26 is engaged by a braking member actuated by a handle bar assembly generally indicated at 28. Assembly 28 is mounted on handle bar supporting frame portion 13 and arranged for reciprocatory movement toward and away from seat 16. v 1
Handle bar assembly 28 includes a vertically disposed lever member which is pivotally mounted about a horizontal axis as at 39 between split bracket members 31 which are affixed to frame portion 13 by cross pins 20. Handle bars 32 are mounted on the upper end of lever member 29, while the lower end of said lever member 29 is pivotally connected to a reciprocatory arm 33 as at 34. Arm 33 is supported by a drop bracket 35 afiixed to an intermediate portion of frame portion 14.
A brake roller 36 is mounted on the rear end of arm 33 and bears on the edge 27 of disc 26. A spring 37 connected at one end to a lower portion of lever member 29 and at the other end to bracket 35, biases arm 33 to maintain roller 36 in contact with disc edge 27 in all positions thereof.
It will be apparent that the user of device 10, when sitting on seat 16, with his feet on pedals 25 and his hands grasping handle bars 32, can operate the device in a manner to control the braking action on the pedal assembly 21, by regulating the forward thrust on said handle bars, which determines the pressure applied by roller 36 on disc 26, through lever 29 and arm 33.
Thus, the exercising effect attainable with device 10 is applied to the arms and shoulders, as well as to the legs, thighs and hips of the user, with full control of the extent of exercise by way of handle bars 32. Furthermore, the rotary speed of pedal assembly 21 will in turn, determine the rate of reciprocation of handle bars 32 and the resultant effect on the upper body portions of the user.
It is understood that the outline of disc 26 may be varied to adjust the extent of the reciprocatory movement of handle bars 32 as well as the rate of movement within the cycle.
While device 10 is shown as being operated by the legs of the user as applied to pedals 25, it is understood that the device may be provided with electric motor means for turning the crank shaft 23, While braking action on disc 26 is controlled by handle bars 32, in the manner described above.
As various changes might be made in the embodiment of the invention herein described without departing from the spirit thereof, it is understood that all matter herein shown or described shall be deemed illustrative and not limiting except as set forth in the appended claims.
