Description
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 been provided 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 a different 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.
The springs are connected to the base member at the end opposite
the end where the 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 pass
about 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 bars 30, the lower ends of which are fixed to
opposite 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 10 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.
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 thumb could 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
more general 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.
