Description
BACKGROUND OF THE INVENTION
For thousands of years, the oriental civilizations have studied and
have been deeply concerned with the effect of foot exercise on
nerve and muscle stimulation for improved health and vigor. It is
believed that the stimulation of certain nerves and muscles on the
soles of the feet has a direct effect on the blood pressure, blood
character, digestion, alkalosis, acidosis, and the like within the
body. In any event, it is known that foot comfort and health are
vital to overall health and well-being.
It has long been the practice to apply weighted shoes to the feet
of a wearer to develop the muscles of the legs, back and stomach.
However, walking with such shoes affords no appreciable stimulation
of the nerves located closely adjacent to the soles of the feet.
The present invention is believed readily to provide such desirable
stimulation and is an outgrowth of the long-established historical
interest and concern and modern-day recognition of the value of
such exercise and foot stimulation.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an
improved health shoe for stimulating the nerves and muscles of the
feet.
Another object is to provide such an improved health shoe which is
effective to massage and stimulate substantially all portions of
the sole of the foot of a wearer.
Another object is to provide an improved health shoe of the
character described which utilizes a ground-engaging,
fast-stimulating member in combination with a flowable particulate
material which is interposed the foot of the wearer and the
stimulating member for distributing and transmitting the motion of
the stimulating member to all portions of the sole of the foot
during normal walking activities.
Other objects and advantages of the present invention will
subsequently become more readily apparent upon reference to the
following description and accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring more particularly to the drawings, a health shoe
embodying the principles of the present invention provides an
elongated substantially rectangular frame 10. The frame is of
boxlike construction and has oppositely spaced, substantially
parallel side panels 11 interconnected at their ends by end panels
12. As arranged, the panels provide opposite substantially
rectangular upper and lower edges 14 and 15, respectively, with the
upper edges circumscribing a foot-receiving opening and the lower
edges being adapted for ground engagement.
A foot-supporting panel or partition 20 is disposed within the
frame 10 intermediate the upper and lower edges 14 and 15 thereof
to provide an upper-foot-receiving recess 22 between it and the
upper edge 14 of the frame. The side and end panels 11 and 12,
respectively and the partition 20 may be constructed of any
suitable rigid material such as wood, plastic, metal, or the like,
which may be fabricated or cast as an integral unit, as
manufacturing techniques and other considerations may suggest.
An elongated substantially rectangular opening 25 is formed in the
partition 20 to provide opposite end walls 26 which terminate in
inwardly spaced substantially parallel relation to the side panels
11 of the frame. The opening further includes opposite sidewalls 28
which are obliquely related to the plane of the partition in
downwardly diverging relation to each other.
A pair of roller-mounting bars 30 are secured to the inner surfaces
of the side panels 11 of the frame in contiguous relation with the
lower edge 15 thereof and in supporting relation beneath the
foot-supporting partition 20. An elongated substantially vertically
disposed slot 32 is formed in each of the mounting bars outwardly
adjacent to and in substantially centered relation to the opening
25 in the partition. An elongated, generally cylindrical agitation
or foot-stimulating roller 35 is rollably mounted within the frame
10. The roller includes a pair of opposite axially endwardly
extended axle rods 37 which are rotatably vertically slidably
disposed within the slots 32 of the roller mounting bars 30. The
axle rods are slightly eccentrically related to the longitudinal
axis of the roller to provide a pulsating effect during rotation.
The roller has an upper peripheral portion 39 extendible through
the opening 25 between the end walls 26 thereof in the partition 20
and an opposite lower peripheral portion 40 which is extendible
below the lower edge 15 of the frame 10.
A substantially rectangular membrane 45 of relatively thin
resiliently flexible sheet material is mounted on the
foot-supporting partition 20 in covering relation to the opening 25
therethrough and to the agitator roller 35. A foot-constraining
stirrup constructed of an elongated flexible rope member is mounted
within the foot-receiving recess 22 of the frame releasably to
secure the frame to a wearer's foot 48, as shown in the dashed
lines in FIG. 1. The stirrup provides opposite ends 50 which are
extended through transversely spaced holes 52 in the partition 20
and an opposite looped or bight end 53. An elongated flexible tie
string 55 is looped about the bight end 53 of the stirrup and has
opposite ends 56 which are extended through a bore 57 in the
partition and knotted therebeneath to limit upward travel of the
stirrup away from the partition. A predetermined quantity of a
flowable particulate material, such as sand or the like, is
deposited within the recess 22 upon the foot-supporting partition
20. Leakage of such material through the opening 25 around the
roller 35 is precluded by the membrane 45.
SECOND FORM
A second form of health shoe embodying the principles of the
present invention is shown in FIG 5 and has an elongated
substantially rectangular frame 65 which is substantially similar
to the frame 10 of the first form with the identical components
thereof having the same reference numerals. The second form,
however, distinguishes from the first form in its provision of a
spherical ball-type agitator roller 66 having an upper periphery 67
extendible through the opening 25 in sliding engagement against the
membrane 45.
The roller 66 is loosely constrained within the frame by a lower
partition 68 contiguous with the lower edge 15 of the frame which
has an opening 69 therethrough invertably corresponding to the
upper opening 25 in the partition 20 with downwardly converging
sidewalls 70 rollably capturing the roller therebetween. The roller
further includes a lower peripheral portion 72 which is extendible
through the lower opening 69 for ground engagement. The upper and
lower partitions are maintained in their desired spaced relation by
a pair of spacer blocks 75 disposed therebetween adjacent to the
end panels 12 of the frame.
THIRD FORM
A third form of health shoe, shown in FIGS. 6 and 7, is similar to
the first form of the invention except for the utilization of a
longer agitator roller 80 which is disposed in longitudinally
extended relation within a frame 82 similar in basic construction
to the frames 10 and 65 of the preceding forms. The roller has a
pair of oppositely extended axle rods 84 which are vertically
slidably disposed within slots 86 in a pair of transversely
disposed roller-mounting bars 87. An elongated substantially
rectangular membrane 90 is disposed in covering relation to an
opening 92 through the partition in covering relation to the roller
and which is constructed of a similar material as the membrane 45
but of a somewhat larger size.
OPERATION
The operations of the described embodiments of the subject
invention are believed to be clearly apparent and are briefly
summarized at this point. In all three forms, the foot 48 of the
wearer is disposed upon the particulate material 60 within the
recess 22 of the frames 10, 65 and 82. Each frame is firmly
releasably held in such position on the wearer's foot by the
stirrup 46 stretching over the instep of the foot with the tie 55
extended through the space adjacent to the big toe of the
wearer.
Referring particularly to the first form of the present invention,
with each step of the wearer during walking, the lower periphery 40
of the roller 35 engages the ground or other support surface which
moves the roller upwardly within the opening 25 in the partition 20
in agitating relation against the membrane 45. Such movement is
permitted by sliding movement of the axle rods 37 of the roller
upwardly within the elongated slots 32 in the roller-mounting bars
30. During such movement, the membrane flexes upwardly a
predetermined distance until the upper periphery 39 of the roller
engages the sidewalls 28 of the opening 25. The particulate
material 60 transmits such roller agitation throughout the
foot-receiving recess 22 and converts it into a massaging action
against the sole of the foot 48 of the wearer. The greatest amount
of agitation is, of course, directly transmitted to the ball of the
foot with the particulate material having an incidental massaging
effect entirely along the full extent of the sole and around and
between the toes. The particulate material also adjusts to the
contour of the sole of the wearer's foot better to distribute the
pressures thereagainst.
The described agitation of the roller 35 can be effectively
controlled by the wearer by imposing a substantially longitudinal
force upon the frame 10. However, the roller only rotates in minute
increments to achieve modified pressure effects. Accordingly, the
roller never really acts as a wheel support for any significant
travel. Upon lifting of the foot during a subsequent step by the
wearer, the axle rods slide downwardly through their respective
slots 32 in their roller-mounting bars 30 gravitationally to lower
the roller again to extend the lower periphery thereof in depending
relation beneath the lower edge 15 of the frame. The agitation
within the particulate material 60 is further enhanced by the axle
rods 37 being slightly eccentrically related to the longitudinal
axis of the roller.
The effect produced by the second and third forms of the present
invention is substantially identical to that as described for the
first form. The use of the second form, as shown in Fig. 5
providing the spherical roller 66, requires, however, a greater
degree of skill than that previously described. In this form, the
same agitating action is produced within the particulate material
60 but, however, the roller is permitted indiscriminately to roll
about any axis and to shift transversely of the frame 65 through
the elongated transversely disposed upper and lower openings 25 and
69.
In the third form of Figs. 6 and 7, with the roller 80
longitudinally extended with respect to the frame 82, a greater
stimulus is provided transversely of the foot of the wearer with
some transverse shifting of the frame being permitted by rotation
of the roller during ground engagement. Although not shown, the
roller may be disposed in any desired angular relationship to the
frame to impart a slightly different massaging effect in accordance
with the corrective action required by the person using the
shoe.
In view of the foregoing, it is readily apparent that the structure
of the present invention provides an improved health shoe for
strengthening and stimulating the muscles and nerves of the feet of
the wearer with overall-health-stimulating advantages. In all three
forms, the particulate material provides additional weight to the
frame 10 which can be varied, as desired, to impose the selected
resistance to normal foot movement during walking. The particulate
material further provides an energy-converting medium for massaging
and stimulating the soles of the feet and is effective individually
to massage the toes thereof. The particular material substantially
conforms to the shape of the foot and presents continual
accommodation of the entire length of the foot during each step
taken by the wearer.
Although the invention has been herein shown and described in what
are conceived to be the most practical and preferred embodiments,
it is recognized that departures may be made therefrom within the
scope of the invention.
