Claims
What is claimed as new is as follows:
1. In combination an exercising device comprising a rectangularly
constructed frame, including a foot heel rest assembly, consisting
of a knurled shaft member secured to and supported by a pair of
vertically disposed upstanding members secured adjacent the sides
of two opposing transverse frame members, a weight holding bar
assembly consisting of a shaft member, including a pair of screw
clamp weight collars, secured to a pair of opposing swing arm
members, which are pivotal adjacent to the sides, at one end of the
two forementioned opposing frame members, a pair of weight bar
stops consisting of two vertically disposed upstanding members,
secured adjacent to the sides of said opposing frame members,
positioned beneath, and supporting the forementioned weight holding
bar in proper position for beginning the exercise movement.
2. The structure of claim 1. Wherein said screw clamp weight
collars are comprised each of a length of heavy wall cylinder,
sufficient length to provide stability, including a threaded T
screw, running through a threaded hole set at an angle in relation
to one face of said cylinder.
3. The structure of claim 1. Wherein said weight holding bar is of
sufficient length to accept a number of standard exercise weights,
for the purpose of varying resistance to the exercise movement.
Description
DESCRIPTION
This invention relates generally to exercising devices, and more
particularly to a device useful in the complete development of the
muscles of the lower legs, ankles, and feet.
This device may also be used in the treatment of persons having
foot arch problems, weakened legs or ankles; for example, someone
who requires physical therapy, or one wishing to strengthen the
legs, ankles and feet for other reasons (sports, etc.).
This invention also utilizes a different, and improved, weight
holding collar, which could be used with many other exercising
devices.
The present device permits a person to develop and strengthen the
frontal shin area, of the lower leg. Primarily, this includes the
peroneus longus, gastrocnemius, extensor digitorum longus, tibialis
anterior, and soleus muscle groups. The present device can be set
up within a few moments, to increase or decrease the resistance to
the exercise. This is done by putting on or taking off, standard
weights, as required by the individual. As a person's strength
increases, more weight may be added to increase resistance.
It is an object of this invention, to provide an exercising device
which may be utilized in the strengthening and developing of the
lower leg, ankle, and foot area.
It is another object of this invention to provide an exercising
device, which will permit treatment of the muscles being exercised
with precise therapeutic resistance.
Still another object of this invention is to provide an exercising
device which may be utilized by a person sitting on a chair in
front of the device, without the necessity of permanently anchoring
the exercising device. Adjustment, to the individual person, made
by moving chair further from, or closer to, the exercising
device.
Still a further object of this invention is to provide a new and
improved weight holding collar, which may be used with many other
exercising devices.
These together with other objects and advantages, which will become
subsequently apparent, reside in the details of construction and
operations, 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. I is a perspective view of the exercising device, with both
weight holding collars (FIG. III), in place on the weight holding
bar. No weights are on the bar in this view.
FIG. II is a side view of the device shown in FIG. I, weights are
shown on the device, in this view. Also shown, is the position of
the foot and leg, as placed in the exercise position.
FIGS. IIIa and IIIb are respectively a front view, and a side view,
of the new, weight holding collar, also shown, on the exercise
device of FIG. I, number 1.
Referring now to the drawing, and FIGS. I and II in particular, the
exercising device may be seen to include a frame, indicated
generally at 2. The frame is preferably constructed of 2-inch angle
steel, and is secured, in a rectangular relationship, by means of
welding or the like.
Referring again to FIGS. I and II in particular, the exercising
device may be seen to include a heel rest indicated generally at 3,
and consisting preferably, of a knurled (roughened) section of 1
inch diameter pipe 3, secured to two upstanding members 4 and 5.
These members, 4 and 5, are then secured to frame members 6 and 7
respectively.
Referring further to FIGS. I and II, the exercising device may be
seen to include a weight holding bar, indicated generally at 8, and
preferably consisting of a section of 1-inch diameter steel bar.
Secured to the weight holding bar 8, are two swing arm members 9
& 10. These members 9 and 10 are preferably made of 1/4 inch by
11/2 inch flat steel, and are pivotal at points 11 and 12, on frame
members 6 and 7 respectively. Hardened steel bolts, and locknuts
may be used as pivots, at points 11 and 12.
Referring now to FIGS. I and II, the exercising device may be seen
to include a pair of weight bar stops, indicated generally at 13
and 14. These stops 13 and 14 are secured by welding or the like,
to frame members 6 and 7 respectively. As best seen in FIG. I, the
stops are located directly beneath the weight holding bar 8, so as
to hold the bar in a desirable position for beginning the exercise
movement.
A further feature of this invention allows for the heel rest 3, to
be made adjustable. As this may be designed many different ways, no
attempt is made to illustrate it here. This feature would allow the
device to accept a wider range of foot sizes.
Referring now to FIG. III, the weight holding collar 1, preferably
consists of a steel ring 1, with a center hole designed to
accommodate the weight holding bar being used. This design further
incorporates a threaded T screw 15, running thru a threaded hole
16, set at an angle, in the steel collar 1. The angle of the
threaded hole is set so as to allow the T screw to be turned, while
the collars front face 17 is pushed against the exercise
weights.
Referring now to the operation of the device in FIGS. I and II, the
exercising device would be placed on the floor with preferably a
chair 18, facing the heel rest 3, in a position suitable to the
individual exerciser. With the exerciser seated in the chair, heels
resting on the heel rest bar 3, toes positioned beneath the weight
holding bar 8 (FIG. III), the exercise may be begun by sliding back
slightly in the chair, and pulling up and back with the toes. After
pulling up the toes, (direction of arrow, FIG. II) the weight is
released, so as to stretch the exercised area fully. This up and
down movement with one or both feet is repeated until the lower leg
is exercised completely. Resistance may be varied by adding or
subtracting weight as required.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and 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, falling within the scope of the
invention as claimed.
