Nissenbaum ABSTRACT: Two upright levers extending down to near the floor,. are swingably mounted in spaced relation on a stand. Each of two foot pedals has a roller near its rear end to roll on a track which extends rearwardly on the floor from the stand, and said pedals at forward end are swingably mounted to the bottom end of said levers respectively. All axes are horizontal and parallel. The pedals are to stand on, and for most exercises the upper parts of the levers are grasped in hand. The pedals are near alongside each other. The handle portions are further apart.

EXERCISER AND PHYSICAL REHABILITATION APPARATUS.
The present invention relates to exercisers which are alsomovement on weakened arms, or with comparatively stronger arms, to impose movement on weakened legs.
Still a further object thereof is to provide novel and improved exercising apparatus of the character described, having the mentioned attributes, and which is simple in construction, reasonable in cost to manufacture, easy to use, and efficient in carrying out the purposes for which it is designed.
Other objects and advantages will become apparent as this disclosure proceeds.
For one practice of this invention, two identical generally upright levers are independently mounted for swinging movement about a common axis on a stand; the lower part of each lever being a downwardly directed clevis, the distal ends of who arms are near the floor. Fitted within each clevis, is the forward end of an elongated pedal which is swingablyf mounted thereon; each pedal having near its rearward end, a rotatably mounted roller as a support therefor on a track rod extending along the floor, rearwardly from said stand. All axes are horizontal, parallel. The pedals are for the user to stand on, and are close by each others side. The upper position of the levers are to be grasped in hand. The intermediate portions of said levers starting from immediately above the levers axis of swing, are upwardly divergent, so the handle portions are further apart to suit mans build.
Various manners of manipulation and a more detailed description of a preferred embodiment of this invention will now be given, for which, recourse will be had to the accompanying drawing wherein similar characters of reference indicate corresponding parts in all the views.
FIG. 1 is a perspective view of an exerciser and rehabilitation apparatus embodying the teachings of this invention.
FIG. 2 is a side view of FIG. 1, indicating one manner of manipulation; the user being shown diagrammatically.
FIG. 3 is a perspective view of the frame member, a stand.
FIG. 4 is a perspective view of one of the levers which is swingably mounted on the stand as shown in FIG. 1.
FIG. 5 is a perspective view of one of the pedals, shown inverted to expose its supporting roller. I
In the drawing, the numeral designates generally an exerciser apparatus comprisinga stand indicated generally as 16, which on an axis rod 17 spanning the distal ends of its U- shaped stand component, there are swingably mounted the two identical upright levers denoted generally by the numerals I8, 118' respectively, which are positioned one right, and the other left, separated by a short tubular central spacer 19 on said rod 17. Said levers at their lower ends, are respectively associated with rearwardly extending, elongated pedals 20 and 20', having rollers as 22 which ride respectively on track rods 21, 21, respectively extending rearwardly from the base rail 23 of the stands U-member, which also has forward legs 24, 24' to make the stand sturdy on the floor. The construction of each lever and its associated pedal andtheir connections and appurtenances being identical, and all parts being symmetrical in relation to the central vertical plane through the central spacer 19, detailed description as to what is to one side of said plane, shall apply to what is to the other side of said plane, except that one part will be designated by a numeral unprimed, and its corresponding part will be designated by the same numeral primed, but a description for one, will suffice for the other.
The lever 18 comprises a lower part which is a downwardly directed clevis 25, between the lower distal ends of whose arms, the forward end of the pedal 20 is swingably mounted on an axis pin 26. Said clevis arms clear the bottom rail 23 of the stand 16. The pedal may be an inverted channel as shown. Near the rearward end of the pedal, on an axis pin 27,-there is a rotatably mounted roller, the said 22, which as mentioned, rides on the track rod 21, provided with the end stop 28. The upward part of the lever is a rod 30, to serve as a handle. The middle part of the lever is bent upwardly away from the spacer 19, so such intermediate parts 29, 29' of the levers are divergent upwardly, so. though the pedals 20, 20 are close by alongside each other, the handles 30, 30 are further apart, so the apparatus suits mans body build.
' The frame 16 is shown made of tubular stock, and tubular pieces 31, 30 are welded at the top ends of the U-members arms, in alignment, so they serve as bearings for the axis rod 17. Each clevis is offset towards the central spacer 19, from the general line of the lever it is part of. The bight 34 of the clevis is tubular and of course straight and open-ended, so it shall serve as a bearing for the lever, on the axis rod 17. The rear ends of the track rods 21, 21' are welded to a tie bar 32 which rests on the floor. The-pedals may be made of sheet metal, and the remainder of tubing, piping and metal bar stock. Suggested approximate dimensions which are given only as a matter of example, and shall not be deemed restrictive, are for a device 15 for adults, that the stand height is 14 inches by 22 inches from side to side. The length of the track 21 is 15 inches and pedal area is 12 -4 /2inches. The. handles 30, 30' are 20 inches apart and the length of each is 26 inches. The overall height of. the device is 42 inches. All bar stock is /2 X l /zinches, and tubular stock has a l-inch diameter. All other dimensions may be judged in the proportion shown in the drawing. Of course, smaller sizes will be chosen for devices 15, to suit children and teenagers. Forward pedal stops may be added, as at 36.
In all instances in exercising with this apparatus 15, it has been my experience that the user 35 stands on the pedals 20, 20, one foot on each. He may or may not grasp the handles 30, 30, while he works his feet in opposite directions as in skating to shift the pedals that way, or he may grasp the handles and work his hands to move both handles in one direction while the feet are worked to move both pedals in the opposite direction. In physical therapy, a patient 35 who has stronger legs than arms, will hold onto the handles 30, 30, while he powers the pedals with his legs. But if he has stronger arms than legs, he will just stand on the pedals and use his hands to power the handles. It is evident that the weaker limbs will have motion imparted to them and therapists will encourage that they try their own propulsion. It is evident, that in all uses and manipulations, while there occur any limb movements,
that the neck and torso will be subjected to voluntary and involuntary bends and turns. i
This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended that the embodiment shown shall be deemed merely illustrative.
1. In an exerciser of the character described, a stand, two upright levers swingably mounted about a substantially horizontal axis on the stand; the lower ends of said levers extending close to the ground, two pedals swingably mounted at the bottom ends of said levers respectively, to be stood on by the user; the upper parts of said levers serving as handles adapted to be respectively grasped by the hands of the user, and two rollers rotatably mounted on said pedals respectively, supporting said pedals so they can ride on a substantially horizontal surface; all axes of swing and rotation being parallel.
2. An exerciser as defined in claim 1, wherein each pedal has a forward end and a rearward end; said rollers being near said rearward ends respectively, and the connections of said pedals with the respective levers, being at the forward ends of said pedals.
ing the axis of swing of each of said levers.
6. An exerciser as defined in claim 1, wherein the pedals are comparatively close alongside each other; said handles being comparatively further apart.
7. An exerciser as defined in claim 1, including two track bars extending from the stand along the ground; said rollers being engaged on said track bars respectively and in rolling contact therewith.
