Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates generally to exercise devices, more
particularly to devices for exercising the fingers, and most
particularly to finger exercisers for guitar players.
[0003] 2. Description of the Prior Art
[0004] While strumming a guitar with one hand, a guitar player
grips the neck of the guitar with the other hand, placing the thumb
directly behind the neck and pressing down on the guitar strings
with the fingers to make contact with the guitar frets, thereby
changing the sound of the vibrating strings. Similar finger action
is required for playing other stringed instruments, such as
violins, cellos, and the like. This repetitive motion requires a
lot of finger strength. Therefore it would be advantageous to
provide a device for exercising and strengthening the fingers of a
guitar player or other stringed instrument player.
[0005] Many devices are found in the prior art of finger
exercisers. U.S. Pat. No. 4,455,019 to Harris shows an exerciser
for fingers that relies on a series of weights attached to pulleys
which provide a resistive force to fingers inserted into loops.
U.S. Pat. No. D 352,764, also shows a design for a finger
exerciser, wherein the fingers press down a plurality of plungers
that have springs supplying opposing force. Other design patents
include U.S. Pat. Nos. D 419,210, D 418,560, D 418,160, and D
416,299. U.S. Pat. Nos. 6,911,011; 6,406,406; 5,820,522; and
6,951,529 show other prior art. None of the aforementioned utility
or design patents show an exerciser where the user has his or her
thumb in full opposition to the hand, as is required in the use of
stringed instruments, and as provided for in the device of the
present invention.
SUMMARY OF THE INVENTION
[0006] In one aspect of the invention, a finger exerciser has a
frame with a thumb receiving portion that defines a thumb receiving
aperture therein. Four stretchable elements are mounted in a spaced
relationship to a portion of the frame substantially opposed to the
thumb receiving portion and extend toward the thumb receiving
portion. A finger receiving element is attached to the distal end
of each stretchable element.
[0007] In another aspect of the invention, a finger exerciser has a
substantially rigid frame with a thumb receiving portion that
defines a thumb receiving aperture therein. Four springs are
mounted in a spaced relationship to a portion of the frame
substantially opposed to the thumb receiving portion and extend
toward the thumb receiving portion. At the distal ends of the
springs, four finger receiving elements are attached.

DETAILED DESCRIPTION OF THE INVENTION
[0013] FIG. 1 shows a finger exerciser 10 of the invention formed
of a frame 12 having a thumb receiving portion 14 thereof. The
frame 12 has an open interior. Thumb receiving portion 14 defines
therein a thumb receiving aperture 16. Mounted to a portion 18 of
frame 12 that is substantially opposed to thumb receiving portion
14 are four stretchable elements 20. The stretchable elements 20
are mounted in a spaced relationship and extend inwardly into the
open interior of frame 12 from portion 18 toward portion 14.
Connected to the distal ends from the frame 12 of each stretchable
element 20 is a finger receiving element 22.
[0014] FIG. 2 shows an alternate embodiment of the invention
incorporating the same elements but having a circular frame shape.
Finger exerciser 30 is formed of a circular frame 32 with a thumb
receiving portion 34 having a thumb receiving aperture 36. If
desired, the thumb receiving aperature 36 can have a cap (not
shown) in it for limiting the extent of penetration of the thumb
into the aperature. Four stretchable elements 40 are mounted to a
portion 38 of frame 32 that is substantially opposed to thumb
receiving portion 34. The stretchable elements 40 are spaced and
extend toward portion 34. A finger receiving element 42 is
connected to the distal end from the frame 32 of each stretchable
element 40.
[0015] Frame 12, 32 is made of a substantially rigid material, e.g.
plastic, metal or wood. The frames may be of practically any shape
that allows for proper positioning of the fingers of the hand.
Frame 12 is substantially rectangular or slightly trapezoidal but
could also be square or other polygonal shape. If the shape is
substantially that of some type of parallelogram or polygon, the
corners will generally be rounded, as in FIG. 1, so there are no
sharp corners. Frame 32 is substantially circular but could also be
more oval or other rounded form. More elaborate shapes can be used
for appearance but they do not change the operation of the
invention. Thumb receiving portions 14, 34 and stretchable element
attachment portions 18, 38 will typically be somewhat wider than
the rest of frames 12, 32.
[0016] The stretchable elements 20, 40 are preferably springs but
may be any other element that stretches under tension and retracts
when tension is released. For example, rubber straps or bands could
be used. Finger receiving elements 22, 42 may be simple open loops
into which the fingers extend or may be closed finger caps into
which the tips of the fingers are inserted.
[0017] FIG. 3 illustrates the operation of the invention, using a
finger exerciser 30 as shown in FIG. 2. A hand 50 grips the
exerciser 30 with thumb 52 extending into aperture 36 in portion 34
of flame 32. Fingers 54 extend into finger caps 56 (finger
receiving elements 42) which are attached to portion 38 of frame 32
by springs 58 (stretchable elements 40). Springs 58 are initially
in an unstretched position. Each finger 54 can then be contracted
or squeezed toward the thumb 52, pulling against the force of the
spring 58, and then relaxed, letting the spring 58 return to its
unstretched position. By repeating this process over and over, with
all of the fingers, the finger muscles can be exercised and
strengthened.
[0018] FIG. 4 illustrates the operation of the invention in
combination with a simulated guitar neck. A finger exerciser 30, as
shown in FIG. 2, has a simulated guitar neck 60 with frets
positioned on the inside surface of portion 34 of the frame 30. The
thumb 52 extends through aperture 36 in frame 32 and contacts the
undersurface of simulated neck 60. The fingers 54 extend into
finger caps 56 which are attached to the frame 32 by springs 58.
The fingers 54 can then pull against springs 58 until finger caps
56 touch the fingerboard between the frets of neck 60, as is the
case with an actual guitar.
[0019] The finger exercisers of the invention may come in one or
more standard sizes but they can also be customized for an
individual user. An illustrative size of frame 12 of FIG. 1 is
about 7 inches wide and 7 inches high with a frame width of about
1/2 to 3/4 inches. An illustrative size of frame 32 of FIG. 2 is
about 8 inches in diameter with a frame width of about 3/4 to 1
inch. The size should allow for the proper orientation of a hand
gripping the exerciser. Thus the size of the exerciser can be
different for different size hands. The frame could be smaller for
smaller hands, e.g. for children.
[0020] The lengths of the springs or other stretchable elements is
preferably not uniform but varied to account for the different
lengths of a person's four fingers. For example, in FIGS. 1, 2 the
four finger receiving elements are from left to right for the
pinkie, ring, middle and index fingers respectively. The two end
ones have longer springs and are thus closer to the thumb aperture
than the two center ones to accommodate the hand shape and finger
length of a user. One exerciser can be used with either the left or
right hand, either by gripping the exerciser with each hand from
the same side, or else from opposite sides of the exerciser.
[0021] The spring lengths are chosen so that in their unstretched
position, the finger receiving elements are positioned to receive
the fingers of a relaxed hand. The springs are then stretched by
finger motion toward the thumb and relaxed by finger motion back to
the starting position. The spring force or tension is chosen to
provide a reasonable level of exercise. Thus, again, there can be
more than one model, with different spring tensions for different
users. Stronger users may need higher spring tension while weaker
users may desire lower spring force. The spring tensions for
individual fingers may also be different.
[0022] Accordingly the invention provides a simple exercise device
that is designed to provide suitable finger exercise for guitar
players and other stringed instrument players. The exerciser can
also be used for other purposes, e.g. for physical therapy or
therapeutic purposes. Devices for general use or customized devices
for individual users may be provided.
[0023] Changes and modifications in the specifically described
embodiments can be carried out without departing from the scope of
the invention which is intended to be limited only by the scope of
the appended claims.
