Description
This invention relates to certain new and useful improvements in
hand and finger exercising devices nd appliances and has to do,
more particularly, with an innovation which is such in construction
and capability that it lends itself to use in the field of physical
therapy, is readily applicable and removable, and achieves the end
results desired by straightening and opening and closing the
fingers.
The adaption herein disclosed has been perfected with a view toward
enabling the digits of the wearer's hand to efficaciously perform
the contemplated movements of extension and abduction
simultaneously. It will fit either the right hand or left hand and,
therefore, obviates the need for distinct embodiments for each
hand. Made of a predetermined grade and kind of moldable rubber or
rubberlike material it can be wholly immersed in water and can in
fact be acceptably utilize in a therapeutic setting for
hydrotherapy where, for instance, the appliance-equipped hand is
called upon to resort to exercising under water. It is compact and
convenient in size and lends itself to placement in a carrying
purse or in a garment pocket. It is strong and durable and can
withstand repeated and long use and is not subject to damage by
bending, twisting or dripping. The manner of use is of the utmost
in simplicity in that the wearer does not have to cope with or
resort to the use of confusing fastening means, does not have to
other with adjustments during use and need not have special
knowledge to achieve satisfactory results.
In fact and to the ends desired the wearer simply places the five
digit loops around the base of each finger and thumb and
straightens the same while at the same time he spreads them apart
as far as necessary for effectiveness. It follows that the
disclosed appliance can be worn for exercising while the wearer
carries out customary activities. Accordingly, a basketball player,
swimmer or a housewife, for example, can apply and safely wear the
appliance and go right ahead with duties and without encountering
undue restraint or encumbering difficulties.
It is within the purview of the inventive concept to provide
appliances of varying sizes and perfected elastic resistance
applicable to the hands of children and adults and in compliance
with prescribed degrees of resistance and in keeping with the
requirements of the exercises recommended by a physical therapist
or a knowledgeable trainer, as the case may be. Sizes commonly used
are made for children and more particularly for adults such as;
small, medium or large. Each size could be produced in three
degrees of elastic resistance, for example minimal resistance
(white), medium resistance (blue), and maximum resistance
(red).
Briefly, the appliance is made of one piece of molded rubber or
suitably elastic rubberlike material and is such in capability that
it can be removably harnessed on the user's hand, without undue
restraint, in a manner to permit the thumb and fingers of the hand
to perform movements of extension and abduction simultaneously and
coincidental with normal neuromuscular actions of that hand. It is
characterized by a plurality of individual loops of suitable
elasticity which are conformable with and adapted to comfortably
but retentatively encircle the base portions only of the thumb and
fingers of a selected hand. These loops have like or corresponding
end portions integrally joined with a prescribed peripheral surface
of normally retracted but stretch responsive connecting means. The
connecting means, more particularly, comprises a simple stress and
strain responsive member which when not in use is in relaxed
ringlike form. To the ends desired this connecting means or member
is permissibly extensible and retractable in response to he opening
and closing movements of the thumb and fingers of the wearer's
hand.
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: FIG. 1 is a view in perspective of a finger exercising
appliance constructed in accordance with the principles of the
invention and showing the component parts in a normal or retracted
state. FIG. 2 is a section taken approximately on the plane of the
central section line 2--2 of FIG 1 looking in the direction of the
indicating arrows.
FIG 3 is a view in elevation showing the appliance applied to the
wearer's hand with the individual loops encircling the thumb and
fingers and with the connecting means or member strained lengthwise
as a result of having spread the fingers and thumb apart to partly
achieve the exercising result desired.
And FIG. 4 is a view of the closed hand with the thumb and fingers
together and with the appliance in its collapsed or retracted
state.
The overall one piece unit or appliance is made of molded rubber or
rubberlike material possessed of the inherent elastic properties
hereinbefore mentioned. This appliance is designated, generally
stated, by the numeral 6. The normally retracted connecting means
or member is denoted by the numeral 8 (FIGS. 1 and 2) and is of
ringlike form. One-half portion of this ringlike member is denoted
by the numeral 10 and the other half portion by the numeral 12. It
is to the outer peripheral surface of the half portion 10 that the
digit accommodating means is connected. This means, more
specifically stated, comprises a cluster of five loops. The loop 14
at the left is designed and adapted to properly encircle the
wearer's thumb as illustrated in FIGS 3 and 4. The other loops,
reading from left to right in FIG. 1, are finger loops and
designated by the numerals 16, 18, 20 and 22 respectively. These
loops embrace the individual fingers also reading from left to
right and shown in FIG. 3.
It will be evident from the views of the drawing that the appliance
6 when not in use is simple, compact and is susceptible of ready
attachment and utilization as illustrated in FIGS. 3 and 4. The
loops 14 to 22 inclusive are fittingly and adaptably applicable to
the thumb and fingers and, in this connection it will be noted,
that the loops are dimensioned so that they encircle only the base
portions of the thumb and fingers. It is evident therefore that the
wearer does not have to deliberate upon the manner of attachment of
the appliance, this being substantially self-evident by merely
glancing at the construction as brought out in FIG. 1. The wearer
does not have to fasten straps, adjust the appliance while being
used or have to have any special knowledge of physical therapy
treatment and appliances. To the ends desired he merely puts a loop
around the base of each finger and thumb and straightens the same
while spreading them apart as far as permissibly possible. Ease of
application and removal saves the wearer time. The outer joint of
the thumb and outer joints of the respective fingers are neither
shackled nor fettered and lend themselves to use without
encumbrance or difficulty.
It will be evident that the appliance when in use allows the digits
to perform both extension and abduction simultaneously. This
pattern of combined movement (extension and abduction) coincides
with the normal neuromuscular action of the hand as when used for
example in reaching for an object, grasping the object, and
releasing the object. As a simple test of this statement, try the
following: place both hands in your lap. Now, with either hand
reach for some object on a desk--say a book Note the digits both
straighten (which is extension) and separate (which is abduction).
Thus by utilizing the device, the user is not only strengthening
those muscles responsible for extension and abduction of the digits
but also doing so in a manner at harmony with the normal working
pattern of the hand. Now grasp the object reached for--which, of
course, closes the fingers (flexion) and brings them together
(abduction). Both of these actions or movements are directly
opposite extension and abduction. Now release the object onto the
desk and note the fingers gain straighten and separate--thus
repeating the action this appliance is used for.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications nd changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
shown and described, and accordingly all suitable modifications and
equivalents may be resorted to, equivalents within the scope of the
invention.
