Description
BACKGROUND OF INVENTION
The present invention relates in general to a gymnasium or
exercising machine and, more particularly, to a portable machine
which can be folded into a relatively compact package when not in
use to minimize storage space. Thus, the portable gymnasium or
exercising machine of the invention is well suited for home use, or
in any area where storage space is limited.
The exercising machine of the present invention is of the general
type disclosed in my U.S. Pat. No. 2,682,402, issued June 29, 1954.
More particularly, the invention contemplates an exercising machine
which includes an elongated base having first and second ends, a
platform on and movable longitudinally of the base, spring means
interconnecting the platform and the base and biasing the platform
toward the first end of the base, stop means for limiting movement
of the platform toward the first end of the base, and various
exercising implements carried by the base and against which the
user may push or pull to displace the platform in opposition to the
spring means acting on the platform.
SUMMARY AND OBJECTS OF INVENTION
A general object of the invention is to provide an exercising
machine of the foregoing general character which incorporates
various improvements on that disclosed in my aforementioned
patent.
More particularly, an object of the invention is to provide an
exercising machine wherein the spring-biased platform is a member
on which the user sits, kneels, or stands in pushing or pulling
against the various exercising implements to displace the platform
in opposition to the spring means acting thereon.
Another object is to provide adjacent the first end of the base a
first foot rest against which the user may push with his or her
feet to displace the platform toward the second end of the base
while seated. A related object is to provide the platform with a
retractable rest against which the user may push while seated, or
kneeling.
Another object is to provide an upstanding frame carried by the
base adjacent the first end thereof, and a second foot rest carried
by the frame at a level above the first foot rest and between the
first foot rest and the second end of the base. With this
construction, the user, while seated, may push against either the
first, lower foot rest, or the second, upper foot rest, or both,
thereby exercising different leg muscles.
Another object is to provide an exercising machine wherein the
frame at the first end of the base is retractable downwardly, along
with the second foot rest, and wherein the first foot rest is also
retractable downwardly, the first foot rest being supported in its
operative position by chains connected to the frame mentioned.
Still another object of the invention is to provide a downwardly
retractable, upstanding frame on the base adjacent the second end
thereof, and to provide various exercising implements on this frame
and engageable by the hands or feet of a user on the platform.
Another object is to provide an exercising machine of the foregoing
nature wherein certain of the exercising implements are stirrups
respectively connected by chains to laterally spaced, horizontal
arms on the frame at the second end of the base. A related object
is to provide a construction wherein the arms mentioned are
pivotable about vertical axes between extended positions wherein
they project laterally outwardly away from each other, and
retracted positions wherein they project laterally inwardly toward
each other, thereby minimizing the amount of space required for
such arms when the frame carrying them is retracted downwardly.
Still another object is to provide on the frame at the second end
of the base a transverse rod, a pulley movable laterally along the
rod, a chain connected to the pulley, and a handle connected to the
chain. With this construction, various combinations of muscles can
be exercised by pulling on the chain, while seated, kneeling, or
standing on the platform, and simultaneously maneuvering the handle
to cause the pulley to run back and forth laterally along the
rod.
Another object is to provide a construction wherein the rod is
carried by an auxiliary frame pivotable between upper and lower
positions to vary the angle of pull by the user, thereby permitting
the exercising of different combinations of muscles.
It will be noted that the various elements hereinbefore discussed
which are carried by the base are all retractable downwardly
relative to the base to minimize the amount of storage space
required, which is an important feature.
Another important object is to provide means for readily adjusting
the spring force applied to the platform by the spring means, by
varying the number of springs acting on the platform.
The foregoing objects, advantages, features and results of the
present invention, together with various other objects, advantages,
features and results thereof which will be evident to those skilled
in the exercising machine art in the light of this disclosure may
be achieved with the exemplary embodiment of the invention
described in detail hereinafter and illustrated in the accompanying
drawings.

DESCRIPTION OF EXEMPLARY EMBODIMENT OF INVENTION
The exercising machine of the invention is designated generally by
the numeral 10 in the drawings and includes as its major component
an elongated base 12 which may be placed on the floor, or any other
suitable supporting surface 14. The base 12 is formed in two parts
16 and 18 pivotally interconnected by a transverse hinge 20, FIG.
2. This permits the part 18 of the base 12 to be pivoted in the
counterclockwise direction, as viewed in FIG. 2, into a position
against the part 16, thereby minimizing storage space requirements
for the machine 10.
The exercising machine 10 includes a platform 22, preferably
padded, which is movable longitudinally of the base 12 toward and
away from one end 24 thereof. Such longitudinal movement of the
platform 22 is achieved by rollers 26 thereon running in
longitudinal tracks 28, FIG. 4, on the base 12.
The platform 22 is biased toward the end 24 of the base 12 by a
spring means comprising laterally spaced, longitudinal, tension
springs 30 some or all of which are connected to the platform 22
and to the base 12 adjacent the end 24 thereof, as will be
described. In use, movement of the platform 22 toward the end 24 of
the base 12 is limited by engagement of the platform with a stop 32
on the base. However, this stop may be pivoted downwardly into the
position shown in broken lines in FIG. 2, and designated by the
reference character 32', to permit the platform 22 to move into,
and beyond, the position in broken lines in FIG. 2, and designated
by the reference character 22'.
Considering the springs 30 in more detail, all of them are secured
to fixed anchors 31 on the base 12 adjacent the end 24 thereof, as
shown in FIGS. 1 and 2. The other ends of the springs 30 are
secured to movable anchors 33 (see FIG. 6) having hooks 35 and 37
selectively engageable with transverse anchor bars 39 and 41,
respectively, on the base 12 and the platform 22. By engaging all
of the hooks 37 with the anchor bar 41, all of the springs 30 are
in use to provide the maximum spring force resisting movement of
the platform 22. To reduce the spring force, as for women or
children, some of the hooks 35 may be engaged with the anchor bar
39 on the base 12 to eliminate the forces applied by the
corresponding springs 30. In effect, such springs are "stored." The
anchors 33 may be shifted between the active anchor bar 41 and the
storage anchor bar 39 readily by lowering the platform stop 32 and
raising the foot rest 50 (to be described). This permits the
platform 22 to move all the way to the end 24 of the base 12 to
relax the springs 30 for easy shifting of the anchors 33 between
the bars 39 and 41.
The base 12 is provided at the end 24 thereof with a frame 36
having the configuration of an inverted U the lower ends of the
arms of which are pivotally connected to the base 12 by transverse
pivots 38, FIG. 2. The frame 36 is pivotable downwardly against the
base 12 and seat 22, when the machine 10 is not in use, to minimize
the storage space required. In use, the frame 36 is supported in
its operative position by two laterally spaced braces 40 pivotally
connected to the respective arms of the frame by transverse pivots
42. The opposite ends of the braces 40 are disposed in sockets 44
on opposite sides of the base 12, and are secured in such sockets
by pins 46. When the machine 10 is not in use, the braces 40 pivot
into positions alongside the arms of the frame 36 to minimize space
requirements.
A first, lower foot rest 50 is pivotally connected to the end 24 of
the base 12 by a transverse hinge 52, FIG. 2. When the machine 10
is not in use, the foot rest 50 lies flat against the base 12, as
shown in solid lines. In use, however, the foot rest 50 is pivoted
in the clockwise direction, as viewed in FIG. 2, into a position
somewhat beyond the broken line position identified in FIG. 2 by
the reference character 50'. The foot rest 50 is supported in its
operative position by transversely spaced, longitudinally extending
chains 52 each connected at one end to the foot rest 50 and at its
other end to the adjacent arm of the frame 36.
One of the exercises which can be performed with the machine 10 is
to push against the lower foot rest 50 with one's feet while seated
on the platform 22, thereby displacing the platform, against the
force of the number of springs 30 in use, in a direction away from
the end 24 of the base 12 and toward the opposite end 54 thereof.
As will be apparent, by alternately pushing against the foot rest
50 and relaxing one's legs, the platform 22 is caused to
reciprocate back and forth longitudinally of the base 12 to
exercise the user's legs.
To brace the user on the platform 22 in pushing against the foot
rest 50 while seated, or kneeling, the platform is provided at the
end thereof farthest from the end 24 of the base 12 with a rest 56.
This rest 56 is propped in an inclined position when the machine 10
is in use, by a brace 58 which is pivotally connected to the rest
and which can be retracted against the rest to permit the latter to
be folded downwardly as viewed in FIG. 2, for storage purposes.
The exercising machine 10 includes, adjacent the end 24 of the base
12, a second, upper foot rest 60 located above the foot rest 50 and
between it and the opposite end 54 of the base 12. The upper foot
rest 60 spans the space between the arms of the frame 36 and is
connected at its ends to such arms. The foot rest 60 can be used in
much the same manner as the foot rest 50, but requires elevation of
the feet and legs to exercise different sets of leg muscles.
It will be understood that the exercising machine 10 can also be
used by pushing on the frame 36 with one's hands while seated,
kneeling, or standing on the platform 22, thereby exercising arm
and shoulder muscles. If desired, the user may push on the frame 36
and the foot rest 50, for example, simultaneously to exercise still
different muscle combinations.
The exercising machine 10 is provided at the opposite end 54 of the
base 12 with various additional exercising implements which are
carried by a frame 70 and which, as will be described, are utilized
by pulling thereof, against the operative springs 30, while seated,
standing, or kneeling on the platform 22. The frame 70 also has the
configuration of an inverted U the arms of which are connected to
the end 54 of the base 12 by transverse pivots 72 which permit the
frame 70 to be folded downwardly against the base 12 to minimize
space requirements. In use, the frame 70 is propped in its
operative position by laterally spaced braces 74 pivotally
connected to the arms of the frame 70 by transverse pivots 76. The
other ends of the braces 74 are notched, not shown, to fit over
transverse pins 78 on the base 12.
The arms of the frame 70 respectively carry pivoted horizontal arms
80 which may be swung through angles of 180.degree. between
positions wherein they extend laterally inwardly toward each other,
as shown in FIG. 5, and positions wherein they extend laterally
outwardly away from each other, as shown in broken lines in FIG. 1.
Stop pins 81 prevent swinging beyond these positions. Stirrups 82
are connected to the ends of the respective pivoted arms 80 by
chains 84. As will be apparent, the user may exercise by pulling on
the stirrups 82 with arms, hands, or feet, with the arms 80 either
extending laterally inwardly toward each other, as shown in broken
lines in FIG. 1. Thus, various muscle combinations may be exercised
with this arrangement.
Also carried by the frame 70 is an auxiliary frame 90 which
laterally spans the frame 70 and which is connected at its ends to
the respective arms of the frame 70 by transverse pivots 92. The
auxiliary frame 90 carries a transversely extending rod 94 which
can be swung between upper and lower positions by pivoting the
auxiliary frame 90 relative to the frame 70. The rod 94 is shown in
its lower position in FIG. 5, and is also shown in it lower
position in solid lines in FIG. 2. The rod 94 is shown in its upper
position in broken lines in FIG. 2. Rollable laterally along the
rod 94 is a pulley 96 connected by a chain 98 to the midpoint of a
handle 100.
A variety of muscle combinations can be exercised by pulling on the
handle 100 while standing, seated, or kneeling on the platform 22
with the rod 94 in either its upper position, or its lower
position. By pulling on the handle 100 with a rocking motion, the
pulley 96 can be caused to roll back and forth laterally along the
rod 94 to change the point at which the pull force is applied to
the rod, and thus change the specific muscle combinations being
exercised.
As will be apparent, the exercising machine 10 of the invention
provides a variety of exercising implements capable of exercising
virtually every muscle in the body when used in sequence or at
random, and in various combinations. Further, as was pointed out
during the foregoing description, the various components connected
to the base 12 can be folded against the base, and the base can be
folded upon itself, to provide a very compact package when the
machine 10 is not in use, thereby minimizing storage space
requirements.
Although an exemplary embodiment of the invention has been
disclosed for purposes of illustration, it will be understood that
various changes, modifications and substitutions may be
incorporated in such embodiment without departing from the spirit
of the invention as defined by the claims appearing
hereinafter.
