PLEASURE SHOE
Abstract
A footwear device that makes walking or standing a pleasure by
aiding in prevention of foot and leg fatigue by putting a "bounce"
in every step; the device consisting of a compression spring unit
that is fitted into each shoe heel and which includes a bottom base
member and top base member that are spaced apart and parallel to
each other, the base members being interconnected by an integral,
resilient, compression coil spring therebetween and which absorbs
the shock of walking and which cushions the underside of a person's
heel.

Claims
I claim:
1. In a pleasure shoe the combination of a footwear shoe having a
heel, and a fatigue arrestor installed in said heel, said fatigue
arrestor comprising a spring mechanism, said spring mechanism
comprising a top base member and a bottom base member with a
compression coil spring therebetween, said coil spring being
resiliently compressible under the weight of a person so to cushion
his walking or standing, said coil spring comprising one full turn
when used by a person where weight is not a factor to consider, and
said coil spring comprising one and one-quarter turn when used by a
person who weighs 200 or more pounds, said coil spring turn being
of a generally square configuration with opposite sides of said
square turn being parallel with said top and bottom bases, said top
base enjoining a lower said parallel side while said bottom base
enjoins a higher said parallel side.
Description
This invention relates generally to footwear such as shoes and
boots for being worn on persons' feet.
It is well known that to date all efforts for eliminating or
ameliorating sore or tired feet have been by incorporating rubber
heels on shoes and other footwear. The rubber wears away and
compacts under the great pressure of heavy walking, so that
depending on rubber for cushioning has not proved to be ideal.
Accordingly, it is a principal object of the present invention to
provide an improved shoe footwear in which a fatigue arrestor is
installed which overcomes the above described situation and which
provides a cushioning and shock absorbing action throughout the
life of the shoe or heel.
Another object is to provide a pleasure shoe which is designed in a
model for supporting persons of normal or light weight, and also in
a model for persons of heavy weight so to absorb the heavier
load.
Still another object is to provide a pleasure shoe in which the
shock absorbing action promotes a person to walk more erect and so
encourage a better general good health.
Still another object is to provide a pleasure shoe that would be
ideal for persons who walk for long hours in their work such as
postmen, policemen, and nurses, or factory workers and others who
stand for long hours on their feet.
Other objects are to provide a pleasure shoe which is simple in
design, inexpensive to manufacture, rugged in construction, easy to
use, and efficient in operation.
These and other objects will be readily evident upon a study of the
following specification and the accompanying drawing, wherein:
FIG. 1 is a side view of the invention shown installed in a
shoe.
FIG. 2 is a top view of one model of the invention designed for
lesser weight factor.
FIG. 3 is a top view of another model designed for heavier weight
factor.
Referring now to the drawing in detail, the reference numeral 10
represents a pleasure shoe according to the present invention
wherein there is a spring or torque mechanism 11 that serves as a
fatigue arrestor to a wearer of the shoe. The mechanism 11 is
installed in the shoe heel 12 and comprises a one piece unit that
includes a flat top base member 13, a flat bottom base member 14 in
parallel, spaced apart relation and which are interconnected by a
compression coil spring 15 therebetween. The coil spring comprises
a flexible flat rod 1/8 inch thick and 1/4 inch wide spring steel.
Where the intermediate full circular spring enjoins the bases it is
horizontal at opposite side from where segments extend relatively
vertically. These opposing ends give a yielding "springboard"
action to not strain the heel.
The model A in FIG. 2 is designed for persons wherein weight is not
a factor to consider, while model B in FIG. 3 is designed for heavy
persons such as those who weigh 200 or more pounds.
Compression between the external contact surface of the heel and a
shoe plateau, on which the foot rests, makes it desirable to cement
the spring cushion heel rest to the plateau of the shoe sole and
the top side of the compiled spring to a complete coverage of
sponge rubber for additional cushioning.
The pleasure shoe is adaptable for all shoe styles for men or
women. The purchasers of the shoes are fitted to the fatigue
arrestor by being fitted in the store. The pleasure shoe is
trouble-free and long-lasting.
While various changes may be made in the detail construction, it is
understood that such changes will be within the spirit and scope of
the present invention as is defined by the appended claims.
