FORElGN PATENTS OR APPLICATIONS 11 Cl 6 D F 445.978 9/1912 France 272/67 rawmg gums FINGER EXERCISING DEVICE The present invention relates to an exercising device and especially to an exercising device for exercising the fingers.

Exercises are often required for the fingers to strengthen the fingers, the hand, the wrist, and the forearm, or for therapeutic reasons when the fingers or portions of the hand have been injured. Heretofore, there has not beenprovided any scientifically designed exercising device for exercising the fingers in such a manner that reasonably predictable therapeutic results can be obtained.

The muscles pertaining to the fingers accomplish flexing of the fingers and bending thereof and extend along the fingers and hand and into the forearm and it is, at times, desirable to exercise these muscles, as well as to flex the finger and knuckle joints for reasons of therapy or development. Proper exercise of such muscles and joints should be balanced to provide for proper results while, at the same time, individual exercise of one or more fingers or joints may be needed.

Also, there are times when it is desirable for a certain degree of traction to be employed in connection with therapy and exercize of the fingers and heretofore known procedures for exercising the fingers of the hand have been deficient in providing for any degree of traction.

With the foregoing in mind, a primary objective of the'present invention is the provision of an exercising device for the fingers of the hand which is operable for influencing muscles pertaining to the fingers and to the hand'and also to the wrist and forearm.

Another objective of the present invention is the provision of an exercising device of the nature referred to which is relatively inexpensive and which is compact so that it can be moved about readily.

Still another object of" the present invention is the provision of an exercising device in which different muscles can be selectively exercised.

Still another object is the provision of a device of the nature referred to which is readily adjustable to provide for different degrees of resistant to movement of the fingers during exercising and to accommodate for hands of adifferent size.

These and other objects and advantages of the present invention will become more apparent upon reference to the following detailed specification taken in connection with the accompanying drawings in which:

FIG. 1 is a perspective view showing a device according to the present invention.

FIG. 2 is a plan view of the device.

FIG. 3 is a side view thereof.

FIG. 4 is a fragmentary view drawn at enlarged scale showing. the device in use in one manner.

FIG. 5" is a view like FIG. 4 but shows the device to use in another manner.

FIG. 6 is a fragmentary view drawn at enlarged scale showing an adjustment associated with the device.

BRIEF SUMMARY OF THE INVENTION According to the present invention, an exercise device is provided having a base member with an upwardly facing surface on which the forearm is adapted to rest'with the hand in a predetermined position along the base member. Near the hand position, finger loops are provided for receiving the fingers of the hand and connected between the finger loops and base member are springs for resisting movement of the finger loops when the fingers are flexed. 1

The springs are connected to'the base member at the end opposite the end where th'e'forearm is received.

The finger loops referred to comprise first finger loops connected directly to the-ends of the springs and resistant to movement in a horizontal direction and which are engaged by the fingers of the hand when the forearm rests on the base member with the palm of the hand uppermost.

Cord-like elements are also connected to the springs and lead over rollers or pulleys disposed above the position where the hand is located and then downwardly and are connected to second finger loops which are engaged by the fingers when the hand is disposed palm down. This last mentioned arrangement provides for resistance to movement of the finger loops in the vertical direction.

The finger loops which are engaged when the hand is disposed with the palm down and which are biased to resist flexing of the fingers downwardly. When the hand is palm down, the fingers tend to flex only at the knuckle joints and the resistance to movement thereof is thus effective for influencing the muscles and the like associated with the metacarpal-phalangeal joints and which constitute the knuckle regions at the base of the fingers.

The other finger pieces, which are engaged by the fingers when the hand is disposed palm up, are employed when flexing the proximal and distal interphalangeal joints of the fingers, which are the finger joints and located between the knuckles referred to above and the final finger sections. By providing the combination of finger loops resistant to flexing of the fingers in the aforementioned manner, substantially complete exercising of the muscles pertaining to the hand can thus be obtained.

DETAILED DESCRIPTION OF THE INVENTION:

Referring to the drawings somewhat more in detail, the device according to the present invention comprises a base member 10 which has an upwardly facing surface 12 leading from one end toward the center and inclined upwardly toward the center. Resting on surface 12 is a mat 14 of resilient material, such as foamed rubber, or elastomer, and which provides a cushion for a forearm resting thereon and likewise inhibits slipping of the forearm on the base member.

Distributed along the base member adjacent surface 12 are strap elements 16 for detachably securing forearm 18 in position on the inclined surface of the base member. The strap elements are adjustable and may advantageously be formed of cooperating elements of Velcro fabric.

With forearm 18 in the position illustrated in FIG. 1, the hand 20 is in a predetermined position near the middle of the length of base member 10. Near this position are first finger engageable means which may consist of flexible strap-like loops 22. Loops 22 are connected to flexible, substantially inextensible, elements such as cords 24 which extend upwardly from the loops and passabout rollers or pulleys 26 carried by support means connected to the base. Such support means might comprise rod 28 secured to the upper ends of sides of the base member.

On the opposite sides of the rollers or pulleys 26 from the finger loops the elements 24 are connected each to one end of a respective tension spring 32, the other end of which is connected at 34 to the end of base member opposite inclined surface 12.

The ends of springs 32 to which cord-like elements 24 are connected carry second finger engageable means in the form of the strap-like finger loops 36.

As will best be seen in FIG. 6, the connection of the springs 32 with the base member 10 is effected by a threaded rod 38 and a nut 40 which are relatively adjustable so as to bodily shift the position of the spring thereby to influence the bias the spring exerts on the respective finger loops. Each threaded rod 38 is clamped to the base member as by a stud and wing nut 42.

The device is shown in operation in FIGS. 4 and 5. In FIG. 4, a hand 20 is arranged palm down and the fingers are engaged with the finger loops 22. With the palm down and the fingers engaged by the finger loops as illustrated in FIG. 4, if the fingers are moved downwardly as indicated by arrow 44, the knuckle joints at the base of the fingers will be flexed and the muscles pertaining to such motion of the finger in the respective direction will be exercised. The fingers can be exercised individually or in groups and the spring pertaining to each finger loop can be adjusted to provide for the desirable resistance to movement of the respective finger. j

In FIG. 5, the hand is disposed palm up and the final joint of each finger is engaged in a respective finger loop 36. With the hand arranged in this manner, the fingers are flexed in the direction indicated by arrow 46,'bending at each joint and thus--exercising all of the joints of the finger. As before, the fingers can be exercised individually or in groups.

When the hand is disposed as shown in FIG. 5, the device also exerts traction on the finger and hand, tending to straighten out joints which might be defective due to tight tendons 'or healed fractured. Also, as before, the individual springs can be adjusted, as desired, to obtain the desired degree of resistance to flexing of the respective fingers or the desired degree of traction applied thereto.

It will be appreciated that the device according to the present invention is relatively inexpensive to construct and is compact so that it is readily portable and that it is flexible with respect to the manner in which exercises can be carried out by using the device.

While the device is illustrated with two sets of four finger loops each, it will be understood that the thumbcould also be exercised by availing of the illustrated finger loops, or by the addition of a further finger loop if so desired.

In general, an individual using the device will be able to retain the fingers in engagement with the finger loops, but in the event there is any difficulty in this respect, a detachable clip 48 as shown in FIG. 1 can be provided which will tend to confine the finger in the respective finger loop and thus prevent the finger from readily slipping out of the finger loop.

The device according to the present invention is useful by physical therapists and is also inexpensive enough to permit patients to purchase one for their own use and can be employed, not only for the purposes of therapy, but also for the purposes of muscle development.

The present invention is described as a finger exercising device, but it will be apparent that the device influences not only the fingers but the entire hand and wrist and forearm and is, thus, of moregeneral benefit than for use merely in the exercising of the fingers. It will be understood, accordingly, that the description and claims are to be considered in this light;

Modifications may be made within the scope of the appended claims.
