ELASTIC PULL TYPE EXERCISER
Abstract
A pull type exercising device including a single piece of
elastic tubing with loops formed at the respective ends of the
tubing by S-shaped hooks that receive folded ends of the tubing. On
each looped portion of the tubing there is a sleeve. A slidable
ring with an anchoring attachment is mounted on the tubular member.
A use inserts an arm or leg in the loops and pulls on the anchored
tubular member.

Claims
I claim:
1. A portable exercising apparatus comprising a single elastic
tubing, a sleeve slipped over each end thereof and exposing a
substantial length of said tubing at its ends, means for receiving
a folded portion of said tubing so that an adjustable loop will be
formed for receiving hands or legs of a user, said means comprising
S-shaped hook having a pair of substantially closed eyelets with
said hook positioned near an end of said tubing, said tubing hooked
through the eyelets thereof forming the adjustable loop in the
portion of the tubing having one of said sleeves thereon, a ring
slidably movable along the length of said tubing for connecting
said tubing to a projection from a stationary object, said sleeves
being mounted on the tubing forming the loops adjacent each hook
for safe exercising without friction burns from the tubing, and a
second sleeve on each end of said tubing for preventing the end of
said tubing from slipping out of said hook, said hook maintaining
sufficient friction between the looped tubing within the eyelets of
said hook for preventing unwanted changes in the size of the loop
once the exerciser sets the loop size for any of his limbs.
Description
This invention relates to a portable and adjustable exercise
apparatus.
The primary object of this invention is the provision of a portable
exercising apparatus which may be simply utilized for toning
muscles, reducing fat, and in some instances, if used in a certain
manner, to develop various muscle groups. It can also be used to
improve a person's golf swing.
Another object of this invention is the provision of adjustable
loops to fit any size person and adjustable tension (provided by
tubing of varying tension) for different age groups and for men and
women.
A further object of this invention is comfortable and safe contact
between the exerciser and the apparatus.
Another object of this invention is that by using a circular ring
and strap, the apparatus can be connected to any stationary object,
which therefore makes said apparatus extremely portable and easy to
use.
The above and other objects of this invention will become apparent
to those skilled in the art after a consideration of the preferred
embodiment of this invention taken together with the accompanying
drawing wherein:
FIG. 1 is a plan view of the apparatus;
FIG. 2 is a sectional view taken on line 2--2 of FIG. 1;
FIG. 3 is a sectional view taken on line 3--3 of FIG. 1;
FIG. 4 is a cross-sectional view of the tubing;
FIG. 5 is a cross-sectional view of the sleeve over the tubing;
and
FIG. 6 is a side elevational view of the apparatus in use.
Referring in detail to the drawing, there is shown a length of
rubber surgical tubing, elastic tubing 20, or the like having a
ring 22 thereabout at the center of the length thereof. A leather
strapping 24 is fastened to ring 22. Ring 22 can be connected to
any heavy object 28 by using a leather strap 24 tied to a leg 26.
Each end 30 of tubing 20 has slipped thereover a sleeve 32 made of
fabric or like material. Each end 30 is then slipped through an
S-shaped hook 34. Each end 30 has either a sleeve 36 extending
therefrom or a tied knot 38 for preventing end 30 from slipping out
of hook 34 as the apparatus is being used. It should be noted that
hook 34 is of appropriate dimensions in order to provide the proper
amount of friction between looped tubing 20 within hook 34 so that
the loop 40 neither increases or decreases in size once set by the
exerciser.
Loops 40 are put over a person's limbs (arms or legs) or held by
the person's hands in doing the various exercises, sleeves 32
preventing slippage and friction burns as the person exercises as
well as providing a comfortable but snug fit about one's limbs such
as when loops 40 are about a person's legs as he is doing a leg
curl, a straight rear leg raise, a leg crossover, a leg raise, a
forward leg raise, or a leg extension when doing exercises for the
hips and thighs.
It should be noted that the exerciser may hold the loops with his
hands for doing sit-ups for the waist, arm crossovers for the
muscles of the chest, a frontal raise for the front of the
shoulder, lateral raises for the side of the shoulder, rowing for
the back of the arms and the shoulders, and arm curls for the
biceps. Tubing 20 of different diameters can be used to provide the
right resistance for men and women of all ages to help them improve
their appearance, muscle tone, strength, endurance, and physical
fitness. The device is excellent for reducing and firming the
women's hips, arms, thighs, waistline, back, and bust line. If used
in a certain manner, the apparatus can also be used to develop the
muscles of the chest, and therefore improve the size and contour of
the bust line. The device can be used safely by the handicapped or
those with serious health conditions in addition to athletes and
businessmen.
While the preferred embodiment has been illustrated and described,
it will be understood by those skilled in the art that many
modifications and changes may be resorted to without departing from
the spirit and scope of the invention. For instance an eyelet screw
can be connected to a snap clasp which is connected to ring 22
enabling the exerciser to easily and quickly disconnect and connect
his device without using the leather strap which ties the ring to a
piece of furniture or any stationary object.
