EXERCISE APPARATUS
Abstract
Exercise apparatus is described incorporating a combination of
adjustable leg and arm exercising features. Mounted on one end of a
table is a pivotal leg exerciser which is engaged by the ankle and
pivoted against an adjustable spring force. Mounted on the sides of
the table are hand grips attached by cables to adjustable springs
for exercising the arms, shoulders and chest. Mounted above the
table is a bar which is to be pressed up with the legs against the
force of an adjustable spring. This bar may be pivoted downwardly
from its normal leg exercising position to a lowered position for
pressing with the arms. The hand grips are attached to the bar to
provide the resisting force in this lowered position. In either the
raised or lowered position the bar is supported so that it cannot
accidentally fall on the person exercising.

Description
BACKGROUND AND OBJECTS
The present invention relates to apparatus for use in the field of
physical therapy and physical development such as the training of
athletes. The invention specifically relates to exercise apparatus
which is manipulated by either the upper or lower limbs to develop
the respective associated muscle groups.
One conventional exercise device which is used extensively is the
barbell and one method of using it is to press it either with the
legs or arms from the prone position. The barbell is usually placed
on some sort of rest and pressed upwardly from this point. This
technique involves a certain degree of hazard since there is little
protection should the barbell be dropped. Also, it is necessary to
have available a large number and variety of weights to be
added.
One of the primary objects of the present invention is to provide
on one exercise table several exercise devices which can be used in
a variety of ways and which can be converted from one use to
another. Another object of the invention is to provide exercise
devices which are readily adjustable and which cannot accidentally
fall on the exerciser. All of the features, advantages and objects
of the invention will be apparent from the following detailed
description.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings, the apparatus of the present
invention comprises a table generally designated 10. This table is
formed from a top frame 12, which includes a pair of side members
14 and end members 16 and 18. Legs 20 support the frame 12 and the
table at each corner. Attached to the legs a short distance off the
floor is a second frame composed of side members 22 and end members
24. Resting on top of the frame 12 and fastened thereto is a table
top 26 which is suitable padded and on which the person exercising
either sits or lies.
Extending outwardly from the end members 16 of the frame 20 and
attached thereto are a pair of support brackets 28. Extending
between the brackets 28 is shaft 30 and pivotally mounted on the
shaft is a leg exercising device generally designated 32. This
device comprises two arms 34 and 36 generally at right angles to
each other. Attached to the end of arm 34 is a crossbar 38 while
another crossbar 40 is attached to the end of arm 36. Also attached
to the arm 36 is one end of a resilient tension means comprising a
spring 42. The other end of the spring 42 is adjustable to a
variety of anchor positions whereby the pull of the spring on the
arm 36 can be adjusted. In the illustrated arrangement, the
adjustable anchor comprises tube 44 which has slots 46 in each
side. The rod 48, which is attached to the end of the spring 46,
fits into the selected notches 50 along the lower edges of the
slots 46.
The leg exercising device 32 can be operated several ways. For
example, the person can lie face down on the table and hook the
crossbar 38 with the heels or back of the ankles. The person then
merely lifts by bending the legs at the knees which develops the
back of the thighs and calves. This device can also be operated by
sitting on the end of the table with the legs hanging down over the
edge. The crossbar 40 is hooked with the front of the ankles and
the lower leg is then raised to pivot the crossbar 40 out and up so
as to exercise the front of the thighs. If desired, padded rollers
can be mounted on the crossbars 38 and 40 for comfort and ease of
operation. As previously stated, the spring 42 can be adjusted to
regulate the tension on the device 32. As a further means for
adjusting the forces on the device 32, weights may be added to the
ends of the crossbar 40. As can be seen in FIG. 3, a slot 52 is
formed in the table top 26 to accommodate the swing of the arm 34
as it is pivoted.
Another feature of the invention is the arm exercising device
generally designated 54. This device comprises handles or hand
grips 56 on each side of the table. Each handle is attached by a
cable or other flexible strand 58 to a spring 60. The cables ride
in the pulleys 62 mounted on the side members 22. The U-shaped
members 63 attached to the side members 14 through which the cables
58 pass support the handles 56 in the lowered relaxed position and
serve to hold the cables in position. This is more clearly shown in
FIG. 4. The tension on springs 60 can be adjusted in a manner
similar to that of the spring 42. Both of the springs 60 are
attached to a rod 64 which is held in position in the selected
notches 66 in the brackets 68. The person exercising merely adjusts
the rod 64 to the desired position in the brackets 68, lies face up
on the table, grasps the handles 56 and presses up. The rod may be
placed in different positions in each bracket so that the tension
on the two springs will be different. Also, the springs can be
replaced with other resilient tensioning means. This arm exercising
device may also be used in a different manner as will be described
hereinafter.
The next feature of the invention which will be described serves
alternately as a leg and arm exerciser. The leg exercising aspect
will be described first. Supports comprising tubes 70 which are
formed of sections 70a and 70b are located on either side of the
table 10 and fastened to the side members 14 and 22. These tubes,
which extend in a generally vertical direction, may be either
directly vertical or at a slight angle to the vertical. Across the
top of the tube sections 70a is a bar 72. The bar 72 is movable
with respect to the tube sections 70a but is attached to rods 74
which extend through the sections 70a as shown in dotted lines in
FIG. 5. Fastened to the bottom of the rods 74 are springs 76 which
extend down into the tube sections 70b. The bottoms of the springs
76 are attached or anchored to adjustment rods 78 which are
adjustable in the notches 80 to vary the spring tension as with the
other spring adjusters The tube sections 70a are pivotally attached
or hinged to their respective tube sections 70b by the hinges 82.
Hooks 84 opposite the hinges hold the tube sections in the position
shown in FIGS. 1, 2 and 3. The person exercising adjusts the
tension of the springs 76 as desired, lies on his back on the table
and presses up with his feet on the bar 72 against the force of the
springs 76. If additional weight is desired beyond that attainable
from the springs, conventional barbell weights can be added to the
outer ends of the bar 72.
This last discussed portion of the apparatus can also be used to
exercise with the arms as previously mentioned. This is
accomplished by unfastening the hooks 84 and folding the tubes 70
at the hinges 82 to the generally horizontal position shown in FIG.
5. When the apparatus is used in this manner, swivel rests 86 are
moved from the position shown in FIG. 1 to the position shown in
FIGS. 3, 4 and 5. This prevents the bar 72 from coming down on the
exerciser and provides sufficient clearance to enter and exit. The
handles 56 are then hooked to the bar 72 by means of the hooks 88
on the bar 72 as shown in phantom in FIG. 5. The springs 60 thus
act to hold the bar 72 down against the force of the exerciser's
arms. If desired, additional weights can be added to the ends of
bar 72 to increase the load over that afforded by the springs. The
rests 86 are tubes or bars which are rotatably supported on bolts
90. The bolts 90 are attached to the U-shaped members 63 as shown
in FIGS. 3 and 4. The rests 86 are held in either the horizontal or
vertical position by the cradle pieces 92. These pieces 92 are
curved and shown in the top view of FIG. 3 to form the cradles that
hold the rests in the vertical position and have cutouts as shown
in FIG. 4 which cradle the rests in the horizontal position. The
springs 94 force the rests against the cradle pieces to maintain
the rests in the selected position and yet permit their
adjustment.
While a preferred embodiment of the invention has been shown and
describe, it will be understood that this is merely illustrative
and that changes may be made without departing from the invention
as claimed.
