WRIST AND ARM EXERCISER Filed sept. 21, 19Go United States Patent Ofilice 3,633,565 Patented May 8, 1962 3,033,565 WRIST AND ARM EXERCISER Jack Henry Wolski, R.R. 2, Freeburg, Ill. Filed Sept. 21, 1960, Ser. No. 57,581 1 Claim. (Cl. 272--68) This invention relates to exercising equipment, and specifcally to equipment for exercising the hands, wrists and arms of the user.
A principal object of this invention is to provide exercise equipment designed to exercise and strengthen the muscles of the hands and arms.
Another object of the invention is to construct exercise equipment of the above class which is adjustable for use by people of all ages.
A further object of the invention is to provide an exerciser for the wrist and arms which is adapted to develop coordination in the muscles associated therewith.
A still further object of the invention is to provide a compact exercising apparatus which is challenging in operation, and which may be manufactured at low cost.
The invention consists of two independent hand grips. One of the grips has a concentric bore terminating at one end with a large counterbore. A spigot is retained in the bore and is urged by a spring to project beyond the counterbored end. An extension projects from the grip to terminate with a post located in alignment with the bore. The second hand grip has a mounted indexing member having a disc secured at one end and a center point at the other end. The member is forcibly engaged between the spigot and the post and is adapted such that the disc may be urged inwardly of the counterbore against the spring action of the spigot. The object of the exercise is to align the disc for such engagement when under considerable loading from the spring.
A full understanding of the details of the invention, together with further advantages, will become apparent by reference to the following detailed description of a preferred embodiment thereof, taken in conjunction with the attached drawings wherein:
FIG. 1 is a perspective view of the apparatus being held by the hands of an operator.
FIG. 2 is a side elevation of the device shown partly in cross section to indicate the spring adjustment retained therein.
Similar reference characters indicate corresponding parts throughout the several views in the drawing.
Referring now to the drawing in more detail, the numeral 5 represents a cylindrical hand grip having a concentric bore 6 formed therethrough. The lower end of the bore is internally threaded to receive an adjustable thumb screw 7 having a terminating finger grip 8. The upper end of the bore is reduced to form an inwardly extending collar 9 which communicates with a large counterbore 10 formed in the top end 11 of the hand grip. An extension member 12 is sealed at its lower end with the upper end of the hand grip 5 and extends beyond the end thereof to terminate with a cylindrical post 13 disposed in an axially spaced relationship relative to the bore 6. The hand grip may be made hollow as indicated at 14 if itis so desired. A small piston 15 is formed to slide within the bore 6 and is provided with a projecting spigot 16 adapted to extend through the collar 9 and project beyond the top 11 of the hand grip. The piston is retained against the collar 9 by a compression spring 17 received within the bore between the lower end of the piston and the adjustable thumb screw 7.
A second hand grip 18 is cylindrical in section and is provided with a T-snaped projection extending concentrically from one end of the grip. The projection comprises an axially extending arm 19 which terminates with a transversely disposed and centrally sealed cylindrical index member Zit. The lower end of the member 2i) extends axially and terminates with a concentrically mounted disc 21 adapted to selectively fit in the counterbore lil formed in the hand grip 5. The other end of member 20 is finished with a concentrically mounted center point 24 and may be selectively engaged with the underside of the post 13.
In operation, the device is grasped by the two hand grips 5 and 18 with the hands 22 and 23. After adjusting the thumb screw 7 to the desired tension, the hand grip 18 is positioned such that the index member engages tightly with the center point 24 bearing against the post 13 and the lower surface of the disc 21 engaging with the projecting spigot t6. The object of the exercise is to repeatedly cause the disc 21 to enter the counterbore 10. This operation must be carried out with considerable muscle control and coordination, since the disc 21 may readily slide on the top of the spigot thus falling out of alignment with the counterbore, and the center point, unless carefully aligned with physical control on the return stroke, will fail to engage the post 13. The hand grips may be grasped in numerous attitudes to provide variety in operation and exercise different muscles. In this manner, great precision may be acquired together with substantial physical development in both the arms and shoulder muscles.
Having described the invention in a preferred form, it will be appreciated that some modifications may be made to the precise configuration, without departing from the scope or spirit of the invention, as defined by the following claim.
A physical exercising apparatus comprising, two cylindrical hand grips, one of said hand grips having a concentric hore formed therethrough, an inwardly extending collar formed near the upper end of the bore and communicating with a large counterbore at said upper end, an extension secured to said one hand grip projecting beyond the said upper end and terminating with a cylindrical post disposed concentrically to and spaced apart from the end of the bore, a spigot retained within the bore and projecting outwardly through the collar to extend beyond said upper end, a compression spring received in the bore inwardly of the spigot, means for adjusting the compression of the spring against the spigot, the other of said hand grips having an indexing member projecting from one end, said member being disposed normally to said other hand grip and having a disc at one end and a center point at its other end adapted to be forcibly engaged between the spigot and the cylindrical post respectively, said disc adapted for engagement within the counterbore upon forcing the spigot inwardly of the bore, and said center point adapted for positioning centrally beneath the cylindrical post, said post terminating with a at face.
