Referring now to the drawings in detail, the reference numeral 30
represents an improved parallel bar type exercising apparatus
according to the present invention wherein there is an upstanding
stationary frame 31 that may be secured to a wall of a room or to
the innerside face of a closet door D as preferred.
The stationary frame 31 is comprised of a pair of upstanding,
spaced apart side posts 32, each of which is made from an elongated
upright channel opening forwardly and having parallel sidewalls 33
and an interconnecting channel rear wall 34, the channel posts
being connected together by a plurality of small transversally
extending horizontal channel pieces 35 opening rearwardly. The
elements comprising this frame 31 are made preferably from
stainless steel and are welded together to provide one rigid frame
adapted to lie flush against a wall or door face to support the
operating parts of the apparatus.
The bottom end of each side post 32 is formed with a forwardly
extending integral foot 36 serving as a base upon which the frame
can stand when held against the wall surface. At the upper end of
each of the side posts 32, a portion thereof is cut away so that
the channel configurated post is at an end of the configuration and
converted into a single angular extension 32', as best shown in
FIG. 11 of the drawing. A series of aligned openings 37 is provided
along each post and extension 32' for the purpose of receiving
screws or bolts so that the apparatus may be secured to a wall face
or to the closet door D. At an intermediate portion, between the
upper and lower ends of each of the posts 32, the post is provided
with a forwardly extending platform 38 rigidly secured thereto, as
best shown in FIGS. 4, 5 and 11, the platform 38 and the foot 36
providing support means for a pair of parallel, vertical rods 39
therebetween. Each of the rods 39 is internally threaded at each
end so as to receive a screw 40 having a head that bears flush
against the platform or foot thus rigidly securing the rod to the
side post 32. A rectangular rubber bumper 41 is supported upon the
foot 36 and has a pair of openings 42 therethrough so to receive
the rods 39, as shown in FIGS. 17 and 18. Rubber rings can be used
on the rods 39 in lieu the rectangular bumper 41.
A plurality of stacked cylindrically configurated lift weights 43
are slidably mounted upon the rod 39, each of the weights being
provided with a pair of openings 44 so to receive the rods 39,
thereby permitting the weights to slide vertically along the rods.
These weights 43 are thus slidably movable between the bottom
rubber bumper 41 and the upper ends of the rods.
Each of the weights 43 is made of heave weight metal such as
stainless or iron and includes a cylindrical mass or body with a
side surface 45 which is bounded at its upper edge by a circular
top wall face 46 and bounded at its lower edge by a bottom wall
face 47, and all of the weights being of relatively equal diameter
and thickness. As is shown in FIG. 18 of the drawing, the uppermost
weight 43A and the lowermost weight 43B are specifically different
in construction from the intermediate weights 43C. Means are
provided for selectively interconnecting the weights together so
that one or any more of the weights may be lifted. Thus, a person
can adjust the total weight that is to be raised. Each of the
weights 43A and 43C have a bottom downwardly extending central plug
portion 48 of cylindrical configuration and the weights 43C and 43B
have cylindrical recesses 49 in the top side thereof.
A sliding bolt assembly 50 selectively secures a plug portion
within an associate recess to a lower weight. As shown in FIG. 18,
each of the sliding bolt assemblies 50 includes a bar 51 which is
slidable in a direction that is slightly tilted relative to a
horizontal direction from the outside inwardly whereby the bar 51
moves slightly downward when moved inwardly to effect lifting
engagement of the weights to one another. As is readily evident in
FIG. 18, only the bottom and intermediate weights 43B and 43C have
the sliding bolt assemblies, and each of these weights include an
opening 52 for slidably receiving the bar 51 in an engaged or
disengaged position, as shown. Only the weights 43A and 43C include
the plug portion 48 to provide engagement means with a weight
located immediately therebelow. Each of these plug portions have an
opening 53 into which the end of the bar 51 is slidable to effect
an engagement as is shown by the three uppermost sliding bolt
assemblies in FIG. 18. Each of the sliding bolt assemblies 50
further includes a channel configurated handle 54 that is secured
pivotally free to the bar 51 by means of a pin 55. The handle 54 is
thus pivotable about the bar 51 between the positions illustrated
in FIGS. 18 and 20 thereby permitting the bar to be in engagement
or retained out of engagement with an adjacent weight.
The uppermost weight 43A has a pair of parallel upstanding brackets
56 welded thereto, and with openings therethrough for receiving a
pin 57 upon which a pulley 58 is freely rotatable. The brackets 56
are provided by a U-shaped weldingly secured by its bight portion
56' to the top wall face 46 of the weight.
A U-shaped member 65, shown in detail in FIG. 12, is welded by the
ends of its legs to each of the channel side posts 32 at an
intermediate point between the lowered weights 43 and the top
platform 38. The forward end of the member 65 is rounded and a
sleeve 66 is welded thereto for receiving a vertical extending
swivel pin 67 on the lower end of a pulley bracket 68 that holds a
pin 69 which supports rotatably free a pulley 70.
As shown in FIG. 17 of the drawings, the upper platform 38 has a
cylindrical sleeve bearing 80 welded thereto, the sleeve having a
central opening for receiving therein a pin 81 on U-shaped bracket
82 that supports a transverse pin 83 upon which a pulley 84 is
freely rotatable. The rope 73 extends around the upper side of the
pulley 84 and the terminal end of the rope 73 is provided with a
hook element 85 fastened thereto. Additionally, as shown in FIG.
19, each of the platforms 38 has a tapered bushing 90 welded
thereto and into which the other terminal end of the rope 73 is
received. A conically configurated wedge 91 is driven into the end
of the rope 73 thereby locking the rope end within the tapered
bushing.
A lowermost one of the transversely extending connecting channels
35 provides support means for a swivel foot support unit 100, shown
in greatest detail in FIG. 13. This foot support unit 100 includes
a pair of forwardly extending arms 101 rigidly affixed to the
transverse channel 35, each of the arms having an angle 102 welded
thereto and to the channel 35 which is more clearly indicated in
FIGS. 7, 8, 15 and 16. One end of each of the arms 101 has a
circular opening 103 therein for the purpose of rotatably receiving
one end of a roller 104.
A leaf spring 105 is secured at one end by a screw 106 to the angle
102, the opposite end of the leaf spring being in alignment with
the center of the opening 103, as best shown in FIG. 8, and this
end of the leaf spring being received within a slot 107 provided at
each end of the roller 104. The roller 104 is rotatable within the
openings 103 and the leaf spring 105 urges the roller to rotate to
a normal return position wherein the leaf spring extends in a
straight line as is illustrated in FIG. 8.
A sidewardly pivotable unit 110 is welded to the normally front
side of the roller 104, and generally comprises a pair of circular
interfitting inner and outer dishes 111 and 112, as best shown in
greater detail in FIGS. 14 and 15. The inner dish 111 is welded to
the roller 104 at 104' and is provided with a semicircular slot 113
and an integrally fixed pin 114. The outer dish 112 is likewise
provided with a semicircular slot 115 and an integrally affixed pin
116. As shown in FIG. 14, the pin 114 on dish 111 is receivable
within the slot of outer dish 112 whereas the pin 116 of outer dish
is receivable within the slot 113, thereby limiting the rotational
movement of the two dishes relative to each other to approximately
180.degree.. A cotter pin 117 or the like is used on the pins 116
and 117 to keep the dishes from being disassembled.
A pair of foot rests 118, best shown in FIGS. 9, 13 and 14 are
rigidly secured upon the front face of the outer dish 112 that is
rotatably mounted upon the stationary dish 111. A pair of
vertically spaced holes 120 are provided in each of the foot rests
and corresponding threaded screw holes 119 in the rotatable outer
dish 112 to receive fastening screws 121 which secure the foot
rests to the sidewardly pivotable unit 110. Each of the foot rests
118 comprises a flat, elongated sheet metal base 122 having a
rounded toe edge 123 and a plurality of parallel grooves 124 so as
to provide rigidity thereto against flexing. A heel brace 125, made
likewise of sheet metal or leather is secured around the lower end
of the base 122 for the purpose of supporting a person's heel
therein. A conventional adjustable strap 126, made preferably from
leather and including a buckle 127 is secured at its opposite ends
to a pair of tabs 128 rigidly affixed upon opposite sides of the
base 122 for the purpose of retaining the front portion of a
person's foot in the foot rest. Thus, a person may secure his feet
to the foot exercising device, pivot them sidewardly and also pivot
them forwardly back and forth against the resistance of the leaf
springs 105.
It will be understood that the foot rests 118 may be mounted on a
plate and the plate mounted on a rotatable sleeve supported by the
arms 101. A coil spring around the sleeve retracts the same as
shown in my U.S. Pat. No. 2,855,200.
A pivotable rectangular generally U-shaped horizontal bar frame 130
is pivotable forwardly upon the stationary frame 31, between a
retracted stored position as shown in FIGS. 1, 2 and 11, and a
forwardly extended, horizontal position as indicated by the dotted
lines in FIG. 2 of the drawing. The frame 130 comprises a pair of
L-shaped tubular horizontal bar members 131 of which is pivotally
secured at its free end to the inner sidewall 33 of frame 31 by a
pin 132. Each of the L-shaped tubular members 131 has a flat tab
133 formed integrally with one end thereof, the tab 133 having an
opening 134 in which is received the pivot pin 132, the pin being
secured in a sidewall flange 33 of the channel side posts 32, as is
best shown in FIGS. 2, 9, 10, 12 and 21. The L-shaped horizontal
bar members 131 extend parallel relative to each other at the
innerside of side posts 32 and at the opposite ends are connected
by means of pins 140 to an H-shaped leg unit 141 to be adjustable
upon the horizontal bar members 131.
This unit 141 includes a pair of legs 142 in parallel spaced apart
relationship and being interconnected together by means of a
chinning bar crossarm 143. Rubber pads 144 in the ends of each of
the legs 142 provide cushion scratch preventing means when the
pivotable frame 130 is tiltable to the floor for support thereon.
When the pivotable horizontal bar frame 130 is in a vertically
upstanding position as best shown in FIGS. 1, 2 and 11, then the
crossarm 143 may serve as a chinning bar.
In order that the same may accommodate persons of various heights,
adjustment means 145 are provided so that the chinning bar 143 is
located in any selected elevation position, as shown in FIG. 2 by
the phantom lines. The adjustment means 145 comprises a lug 146
secured to each of the legs 142 to which one end of a link 147 is
pivotally connected by means of a pin 148, FIGS. 3 and 11. At its
opposite end the link 147 is adjustably connected to a vertical
plate 149 rigidly secured to each tubular member 131. The plate 149
includes a plurality of vertically spaced apart openings 150 into
which selectively a pin 151 may be secured, thereby causing the
H-shaped legs unit 141 to assume either of the positions shown in
FIG. 2. A leaf spring 152 is secured at its one end by a screw 153
to the link 147 and at its opposite end bears pressure against a
head 154 on the pin 151 to normally retain the pin in engagement
and thereby prevent accidentally the same from falling out, the
leaf spring 152 being further provided at the same end with a hook
155 to permit easy lifting of the same so to adjust the position of
the pin 151 selectively to the openings 150. The L-shaped
horizontal bar members 131 and legs 142 may be integral or
one-piece as shown in FIG. 2A and without the adjustment means
145.
When the pivotable horizontal bar frame 130 is pivoted downwardly
into a horizontal position as indicated by the dotted lines in FIG.
2, the same may be made to receive a wheeled rowing seat 160 or
similar structure with wheels 161 upon which a person may sit when
he wishes to use the device for purpose of doing rowing or
bicycling exercises. In such position, the pads 144 are engaged
with the floor. A grasshopper-type fastener 162, has a screw 163
fixed to each side post extension 32' and a pivot plate 162'
supported outwardly from the side flange of the extension by a coil
spring 163'. The plate 162' has a pin 164 receivable within
openings in the sides of the flange extension and the horizontal
bar member 131, for retaining the pivotable frame 130 in an
upstanding position during a chinning exercise or for storage
purposes. Thus the bar frame 130 is releaseably held in a locked
position when raised by the fasteners 162.
As shown in FIGS. 1, 11 and 22, the tubular members 131 may be
bridged by one or a plurality of elongated wooden rollers 165 which
are supported rotatably free at each end within a bracket 166
secured by screws 166' to each tubular horizontal bar member 131.
The roller 165 may be of any configuration, and may have
cylindrical bumps against which a person may lower his body for the
purpose of performing reducing exercises. Each bracket 166 includes
a circular channel 167 with a relatively friction free bearing 168
which supports rotatably directly the reduced diameter roller ends
169. Screw eye bolts 165' are secured in the roller extensions 165'
by a nut 165" and to which a pulley rope hook 85 can be attached so
that lifting of the weights can be effected by grasping the roller
with the hands and twisting to lift the weights.
Conventional gripping handles 170, comprised of a rotatable wooden
roller 171 supported upon a steel wire bale 172 are detachably
secured to each of the pulley hooks 85 at the ends of the ropes 73
when it is desired to pull upon the weights 43 while the person is
on the rowing seat or when standing in front of the apparatus.
In operative use the present apparatus is used for various
exercises such as chinning, rowing, swimming, bicycling, and other
exercises associated with chinning bar, parallel bars and the
lifting weights. When it is desired to use the present apparatus
for rowing exercise, the pivotable frame 130 is lowered forwardly
to the flow and into a horizontal position and the roller seat 161
is fitted thereupon. The person then grasps the grip handles 170
and pulls upon the same thus causing the weights to be lifted, this
force developing the appropriate muscles used for rowing. When the
device is used for bicycling exercises, then the feet, instead of
the hands, may engage the grip handles 170. When swimming exercises
are to be performed, then the grip handles 170 may be grasped
either with the hands or feet while the person is lying in a prone
position face side downwardly upon a seat structure supported upon
the pivotable frame 130.
In FIG. 5, it will be noted that provision can be made for the
standing up of this apparatus in the middle of a floor rather than
from a door by simply fastening long brace bars 172 to the aligned
openings 37 at the upper ends of the posts 32 by bolts 173 and nuts
