Claims
Having thus fully described the invention, what is claimed as new
and desired to be protected by United States Letters Patent is:
1. An exercising device comprising a shoe body, a sole and a heel
of resilient material carried by the shoe body, a plurality of
spaced transverse bores in the sole and heel and elongated weights
receivable within said bores to increase the weight of the
exercising device.
2. A device according to claim 1 in which the bores are slightly
smaller in inside diameter than the outside diameter of the weights
and the weights include an elongated knurled body portion.
3. A device according to claim 1 in which the bores are formed with
a key receiving slot and the weights are provided with an outwardly
extending key receivable in said slot.
4. A device according to claim 1 in which the weights are bullet
shaped and the bores have an inside diameter slightly smaller than
the outside diameter of the weights.
5. A device according to claim 1 in which the weights are provided
with an outwardly extending detent and the bores are formed with a
bayonet slot to receive the said detent.
Description
BACKGROUND OF THE DISCLOSURE
It is well-known to attach weights to portions of the body for
exercising or reducing purposes. Where weights have been used in
conjunction with a person's legs or feet they have generally
restricted the wearer's mobility. As a result, exercises involving
the legs or feet have had to be performed for a period of time at a
given place.
An object of the present invention is to provide an exercising
device which may be worn as a shoe without endangering the wearer's
walking or running activities.
Another object of the present invention is to provide an exercising
device in the nature of a shoe which is easily adjustable as to the
severity of exercise task.
A further object of the present invention is to provide an
exercising shoe which can be worn for prolonged periods of time
both for exercising and weight reduction.
SUMMARY
In one preferred form of the present invention an exercising shoe
is provided with a resilient sole and heel of substantial
thickness. Transverse bores, spaced from each other, are cut in the
sole and heel to receive rod shaped weights. Locking means are
provided to prevent the rods from accidentally coming out of the
bores during use.
DESCRIPTION OF THE DRAWING
In the accompanying drawing, forming part hereof identical parts
have been given the same reference numerals, in which drawing:
FIG. 1 is a view in side elevation of a complete embodiment of the
present invention.
FIG. 2 is a somewhat isometric view of one form of weight according
to the present invention.
FIG. 3 is a cross sectional view taken on line 3--3 in FIG. 1.
FIG. 4 is another form of weight useful in the present
invention.
FIG. 5 is a fragmentary view of an exercising shoe adapted to
receive the weight of FIG. 4.
FIG. 6 is a cross sectional view taken on line 6--6 of FIG. 5.
FIG. 7 is a somewhat exploded view partly in section showing still
another form of weight retaining structure.
FIG. 8 is a view similar to FIG. 7 of a further weight retaining
assembly.
FIG. 9 is a view taken on line 9--9 in FIG. 8 looking in the
direction of the arrows.
GENERAL DESCRIPTION
Referring to the drawing and particularly to FIG. 1, reference
numeral 10 indicates an exercising shoe according to the present
invention. The shoe 10 is provided with a sole 11 of substantial
thickness. It is preferred to make the sole of some resilient
material such as crepe rubber, cork, neoprene or the like. The heel
portion 12 of the shoe 10 is also of substantial thickness and of
the same resilient material as the sole. Heel and sole may be
integral as shown in FIG. 1.
A plurality of spaced transverse bores 13 are formed in the sole 11
and heel 12. The bores 13 are of a diameter which will receive
rod-like weights 14 one of which is shown in FIG. 2.
The weight 14 consists of an elongated cylindrical body portion 15
and an enlarged head 15. The body portion 14 is knurled as
indicated at 16 in FIG. 2 to prevent the weight from slipping out
of the bore 13 while the shoe is in use. To further prevent
accidental displacement of the weights, the bores 13 may have a
slightly smaller diameter than the outside diameter of the weights.
It will be apparent that if the weights 14 should slip even part
way out of the bores 13 the person wearing the exercising shoes
could trip and be injured.
The head 15 of the weights 14 are flat and rest against the side of
the sole 11 or heel 12 when the weights are in place, as shown in
FIG. 3. The weight heads 15 are used to remove the weights 14 from
the bores when it is desired to alter the number or arrangement of
weights to be used.
Any suitable metal may be used for the weights 14 such as lead,
iron, copper or alloys of these metals. In addition, the person
using the shoes may wish to start with only some of the weights
inserted and add others as his abilities increase. Alternately,
more weight may be desired in the heel area than at the front of
the shoe or vice versa.
Referring to FIGS. 4, 5 and 6 there is shown another weight locking
structure in which the weight 14a is provided with a laterally
extending key 17. A keyway 18 slightly smaller than the key 17 is
cut into the bores 13 as shown in FIG. 5. When the weight 14a is
forced into the bore 13 the resilient material will close slightly
behind the key and prevent the weight from accidental longitudinal
movement.
The embodiment shown in FIG. 7 employs a somewhat bullet shaped
weight 14b having a rounded nose portion 18, a cylindrical body 19
and a flanged head 20. The bore 13 is of a size so that its inside
diameter d is slightly smaller than the outside diameter D of the
weight 14b. The weight 14b is forced into the bore 13 to increase
the heaviness of the shoe 10 and the resilient material of the sole
and heel retain the weight in place.
The weight securing structure of FIGS. 8 and 9 is of the bayonet
slot type. The weight 14c is provided with a nub 21 which projects
outwardly of the body portion 22 of the weight. The bore 13 in the
shoe 10 is formed with a nub receiving recess 23 at one end and an
enlarged cavity 24 communicating with the inner end of the recess
23. After the weight 14c is pushed into the bore it is rotated a
few degrees whereupon the nub 21 will become secured within the
cavity 24 and prevent accidental displacement of the weight during
use.
The exercise shoes described above may be used for a wide variety
of purposes. Persons desiring to build up their leg muscles may
wear them for prolonged periods of time during normal activities.
Alternately, they may be used while running or jogging to make the
exercise more strenuous. Since each weight is independent of the
others, the person using the exercising shoe may start with only a
few weights in place and increase them gradually over a period of
time and athletic improvement.
