United States Patent WRIST AND FOREARM EXERCISER Enrique Ugartec-hea, Mexico City, Mexico, assignor of one-half to Rolando Ugartechea, Chicago, Ill.
Application January 13, 1956, Serial No. 559,004
1 Claim. (CL 272-67) My invention relates to improvements in exercising devices for the wrists and forearms of wrestlers.
The primary object of my invention is to provide a rocker device attachable to a table, or the like, and which is convertible for use either in exercising and strengthening the forearm and wrist, or the entire arm, or for practicing wrist and arm wrestling by contestants with elbows resting on the table.
Another object is to provide a device for the above purposes in the form of a rocker device operated by hand grips at opposite sides thereof against spring tension in exercising, or without spring tension in wrestling.
Still another object is to provide for operating the device in exercising against variable spring tension.
Yet another object is to provide a device of the above purposes which is simple inconstruction, safe to use, durable and comparatively inexpensive to manufacture.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a view in perspective of an exercising device constructed in accordance with my invention and illustrating the use of the same in exercising the wrist and forearm;
Figure 2 is a view in perspective illustrating the use of the device in arm wrestling;
Figure 3 is an enlarged View in vertical section, partly in front elevation of the device; and,
Figure 4 is an enlarged view partly in side elevation and partly in transverse section of the device partly broken away.
Referring to the drawings by numerals, the exercising device according to my invention, and which is designated by the numeral 1, comprises a U-shaped rocker 3 of tubular metal for lightness in weight and strength and which is of right angle form to provide a straight bottom portion 5 terminating in a pair of upright side sleeves 7.
Means is provided for mounting the rocker 3 on a table 9, or panel, transversely thereof for vertical rocking movement comprising a pair of bearings adjacent the sleeves 7 including plates 11 supporting the lower portion 5 of the rocker 3 in horizontal position and which are bolted, as at 13, to the table 9 and provided with U-shaped sections 15 welded on said plates, as at 16, and straddling the bottom portion 5.
A pair of tubular hand grips 17 are provided at opposite sides of the rocker 3 and spaced outwardly of the sleeves 7 coplanar with the rocker. The hand grips 17 are inclined upwardly and outwardly of the rocker 3 to facilitate grasping of the same by the hands of wrestlers resting the elbows on the table 9 with the forearm and wrists inclined upwardly to the hand grips 17.
The hand grips 17 are operatively connected to the rocker 3 by means of a tubular, horizontal rocker bridging member 19 extending across the upper ends of the sleeves 7 and provided with a pair of depending legs 21 2,782,033 Patented Feb. 19,, 1957 ice extending downwardly into the sleeves 7, and with a pair of upwardly and outwardly inclined e'nd portions 23}o'n which the hand grips 17 are rotat'ably sleeved. The hand grips 17 are confined on the end portions 23 against endwise play between collars 25 at the inner ends of said hand grips 17 and suitably fixed on said portions 23, and collars 27 on said portions 23 at the outer ends of the hand grips 17 retained on said portions 23 by knobs 29 having stems 31 suitably fixediri the outer end-s of the portions 23.
The bridging member 19 and hence the rocker 3 are tensioned against rocking in one direction by pairs of parallel coil springs 33 extending transversely from the bridging member 19 adjacent opposite sides of the rocker 3. The springs 33 are detachably connected at corresponding ends 35 thereof to eye members 37 on the bridging member 19, and have their other ends 39 anchored to the table 9 by a bracket 41 of inverted U-shape bolted, as at 43, to the table 9 and provided with eye members 45 to which said other ends 39 of th springs 33 are connected.
The legs 21 of the bridging member 19 are slidably adjustable in the sleeves 7 so that the bridging member 19 is adjustable toward and from the rocker 3 to vary the tension exerted by the springs 33 against the rocker 3. Pins 47 insertable in a pair of openings 49 in the sleeves 7 and insertable through selective longitudinally spaced pairs of openings 51 in the legs 21 provide means for retaining said legs 21 and hence the bridging member 19 in adjusted position.
Referring now to the operation of the device, as shown in Figure 1, in using the device as in exercising the forearm and wrist, one or the other of the hand grips 17 is grasped by the hand of an arm rested at the elbow on the table 9 and pressure is exerted by the hand and arm to rock the rocker 3 in opposition to the spring 33 from a substantially vertical position. As will be 'clear, the means for varying the tension exerted by the springs 33 operates by varying the distance between the axis of rocking movement of the rocker 3 and the points of connection of the springs 33 to the bridging member 19. Obviously, the tension exerted against the rocker 3 may be easily varied according to exercising requirements.
To convert the device for wrist or arm wrestling, the ends 35 of the springs 33 are detached from the eye mem bers 37 so that the rocker 3 is freely rockable in opposite directions. The device may then be used for such wrestling by two contestants grasping the hand grips 17 with elbows resting on the table 9, as shown in Figure 2, and engaging in a contest to each rock the rocker 3 in opposition to the other.
It is to be noted that the device may be used in exercising both arms by a person standing at the table 9 in front of the rocker 3 and pulling on both hands grips 17, or by pulling on both hand grips 17 with his elbows resting on the table to exercise both forearms and wrists.
From the foregoing. the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
What is claimed as new is as follows:
In combination, a table, a U-shaped rocker having a bottom portion and upright sides, means pivotally mounting said bottom portion horizontally on said table for vertical rocking of said rocker, a horizontal member bridging said sides, means connecting said member to said sides for rocking the rocker, a pair of hand grips on said member outwardly of said sides for rocking the rocker adapted for grasping by a hand of an arm restin at the elbow on said table, said hand grips slanting up- Wa'rdly from said rocker to facilitate grasping thereof with the forearm slanting upwardly from the table, a bracket of inverted U-shape attached to the table in laterally spaced relation to said rocker, and coil springs attached to said bracket and to said member intermediate said sides for opposing rocking ofsaid rocker in one direction.
