I INVENTOR.

HENIS J. SLAYTON FIGA BY ATTORHEY United States Patent EXERCISE TOYS Henis J. Slayton, Atlanta, Ga. Application February 12, 1954, Serial No. 409,913 Claims. (Cl. 272-68) This invention relates to an exercise toy and particularly to a hand operated device of this sort with means for se lectively extending and retracting a flexible member as the hand and arm are moved.

There is always a need for an inexpensive device which will challenge the skill of or otherwise amuse a child so as to occupy his time and provide him with pleasant recreation. The value of such a device is further enhanced if it provides physical action and exercise as well as requiring some measure of skill since growing children seek an outlet for large amounts of energy. Furthermore, there is a need for such a device for use in rehabilitating adults after illness or accident has damaged certain of their muscles, nerves, and bones.

An object of the present invention is to provide an interesting and amusing exercise toy which is hand operated and which encourages strength and coordination.

An additional object is to provide an exercisetoy which is simple in construction and inexpensive to manufacture.

Another object of the present invention is to provide a hand operated exercise toy which may be readily adjusted to require the application of more hand and arm strength thereby providing a progressive building of muscle and coordination.

A further principal object of the present hand operated exercise toy is an arrangement for keeping a weighted, flexible member moving in different directions with as much speed as possible through the skillful manipulation of the hand.

Generally described, the present invention comprises a base member which may be supported by one hand, a hand control and drive member movably mounted on said base member, a long, thin flexible member mounted for extension and retraction on said base member through the action of said hand drive member, and weight means on the end of said flexible member, whereby said flexible member may be moved at different speeds and in different directions in response to the hand operation of the control and drive member.

Other and further objects and advantages of my invention will be apparent from the ensuing description taken in conjunction with the accompanying drawings, wherein:

Fig. l is a side elevation view of a preferred embodiment of my invention with the flexible member almost retracted.

Fig. 2 is a side elevation view of the other side of the invention in Fig. 1 with part of each of the side walls broken away to expose the drive mechanism.

Fig. 3 is a top plan view of the device taken substantially along the line 3-3 of Fig. 2 and with a portion broken away to show the plunger.

Fig. 4 is a diagrammatic view illustrating in part the manner of operating the present invention.

Referring to the drawings, the device is adapted to be held in the hand somewhat like a pistol and comprises a substantially chambered base or hollow holder member 10 having opposed side walls 12, 14 joined to each other around their margins and being enlarged adjacent the 2,753,483 Patented Sept. 18, 1956 front 16 but narrowing near the upper rear 18 to form a handle grip 20 defining a hand slot 22. Hand grip 20 is provided at the top thereof with opposed finger lugs 24 which serve as additional grips to those who so desire it.

A pulley 26 is mounted for rotation with shaft 28 car ried by opposed sides 12, 14 and has wound thereon a flexible, cord-like member 30 which is fed outwardly from the front 16 of base 10 through a small tubular conduit 32 with a flared or bell-like end 34 passing the member 30 smoothly from the front thereof. Conduit 32 is held in place on side 12 by means of a small plate 36 and screw 38. Flexible member 30 is weighted at the outer terminal end thereof to hang downwardly as by a rubber or plastic ball 40 which may be of any size and shape and of different weights depending upon the particular person for whom the device is constructed. Pulley 26 is arranged to act as a means for retracting and storing the flexible member 30 on the base 10 and is driven by the hand through a drive means comprising a hand plunger 42 with a finger grip 44 and shaft 46 mounted for sliding, reciprocating action in the base 10. Plunger shaft 46 is held between spaced journals 47 on sides 12, 14 and slides in a support block 48. A rack 49 is formed on the inner end of plunger shaft 46 and meshes with a pinion drive gear 50 carried by shaft 52 which is rotatably supported on opposed sides 12 and 14. Also fixed on shaft 52 for movement therewith is a large drive gear 54 which meshes with another pinion gear 56 fixed on shaft 28.

With the above described arrangement, in Fig. 2 as pinion 50 is driven with shaft 52 counter-clockwise through the action of rack 49 moving toward the front 16, drive gear 54 turns pinion 56 clockwise thereby moving its shaft 28 and pulley 26 in the same direction which unwinds the flexible member 30 under assistance from the weight 40. The heavier the weight 40 the more force exerted to unwind the pulley 26 or likewise if weight 40 is already moving then more force is being exerted on pulley 26. Pulling the plunger 42 back toward handle 20 reverses the above described action and thereby re-winds the pulley. In a succession of pushes and pulls the plunger 42 will cause the flexible member 30 to gather momentum in one direction of unwinding and then in the other upon stopping said plunger movement and reversing it so that the member 30 remains substantially in constant motion through the winding and unwinding, centrifugal and centripital forces, and changes of direction of both the hand and the arm. The length of flexible member 30 extended depends upon the distance the rack is moved on the pinion 50 and this length may be readily varied on successive strokes simply by making shorter or longer pulls or pushes on the plunger 42. Coordination of this action becomes more diflicult as the weight 40 gathers momentum and as the speed of winding and unwinding increases.

Plunger shaft 46 is held in place for reciprocatory motion and rack 49 is held in firm engagement with pinion 50 through the confinement of shaft 46 in the journals 47 and the support block 48. All the drive mechanisms except the pulley 26 are normally enclosed within the casing formed by side walls 12, 14 so that there is no chance for the flexible member 30 to become entangled in one of the gears. Likewise, smooth entrance to and exit from the pulley 26 by the member 30 is assured through the use of the conduit 32. Member 30 may be of any preferred diameter and material, such as cord or wire, as long as it is reasonably flexible so that it is readily wound and unwound upon the pulley 26, its function being to provide a fast means of retracting and positioning the flexible member 30 on base 10 and for extending the member 30 in response to the demand created by force on the plunger 42. The relationship between the size of gear 54 and that of pinion 56 is such as to make available suitable speed at the pulley 26 from force exerted on plunger 42.

.muscles by starting first with a Many patterns of movement of the flexible member 30 are possible with the present invention and are primarily a matter of the skill of the person operating the device. Fig. 4 illustrates a few of the basic movements produced upon slight movement of the plunger 42 with a very limited movement of a hand 60. One satisfactory way of holding the device is with the fingers around the grip 44 in the manner of Fig. 4 where fingers 62 are shown in arrangement with two .fingers above the shaft 46 and two below the shaft 46 and with the thumb 64 over one of the lugs 24. This permits complete freedom in actuating the plunger 42 so that it may be pulled or pushed or released at will and during the fast motions. If the hand is rotated slightly at the wrist as the plunger is pulled rearwardly, member 30 is extended and bent at the same time and as the slack tends to appear the plunger is moved forward, or released slightly, to permit the action of the weight 40 to pull the member 30 taut. Further, as member 30 is retracted at rather high speed it is a challenge to the operator to try and keep member 30 taut and to keep it moving outwardly again just as it almost reaches complete retraction. Obviously, the many variations in the use are too numerous to set forth herein as it would be the infinite number of patterns derived from selectively shortening and lengthening member 30 while moving the device at various speeds and in sudden changes of direction. The heavier the weight 40 the more strength that is required to move the plunger 42 and to move the entire device once the flexible member 30 begins to' wind and unwind so the present invention may be readily used in physiotherapy as a progressive means of rehabilitating damaged hand, finger, arm and shoulder light member 30 and to regain coordination then changheavier weights 40 in order torevery light weight 40 ing progressively to gain strength.

Although I have shown and described in detail a particular form of my invention it is pointed out that many changes may be made as for example the gear drive arrangement 49, 50, 54, 56 is readily altered by substituting other gears or eliminating some of those present. Therefore I am not limited to the form presented heretofore since the various alterations, substitutions, eliminations, and modifications are within the scope of my invention as defined in the appended claims.
