Description
This invention relates generally to exercising apparatus, and more
specifically relates to collapsible and storable devices enabling
performance of a wide range of gymnastic exercises.
Within recent years the increasing urbanization and mechanization
of our society has led to a corresponding decrease in the amount of
physical exercise in which the members of our society regularly
engage. And yet physicians and others more generally concerned with
the public health have come to increasingly recognize the causal
relationship between good health and the engagement by the
individual in a regular program of vigorous physical exercise. This
problem is most acute in the case of an urban dweller, who
typically resides in an apartment or other limited space dwelling.
Not only may the nature of such an individual's employment
activities limit his daily physical exercise, but the limited space
of his home surroundings and lack of adjoining grounds, may
virtually preclude a positive effort by him to establish an
exercise program.
In an effort to provide home facilities for rectifying the
aforegoing situation, various knock-down or collapsible exercising
apparatus have heretofore been proposed. By and large, however,
such prior apparatus has not been received with a notable degree of
commercial acceptance. Various reasons may be offered in
explanation of such result, but certainly among the more
significant shortcomings in such prior devices, may be cited the
following: first, the apparatus did not offer the capability for a
wide enough variety of exercises; second, the apparatus was
cumbersome to collapse or convert to the various desired
configurations; and third, the prior apparatus was impractical to
store in a closet or similar space by virtue of its weight and
bulk, and was impractical to store in an open area because of its
unappealing appearance.
In accordance with the foregoing, it may be regarded as an object
of the present invention to provide exercise apparatus, which is
compact and readily collapsible to a storable form, and which
enables the user to perform a very wide variety of vigorous
exercises.
It is a further object of the invention to provide exercise
apparatus which in its functioning configurations is very sturdy
and enables an extremely wide variety of vigorous exercises, which
is readily converted from configuration to configuration to enable
such wide variety of exercises, and which in its collapsed form is
both aesthetically acceptable and useful, whereby such apparatus
need not be removed from the premises of a user or concealed from
view subsequent to employment thereof.
Now, in accordance with the present invention, the foregoing
objects, and others, as will become apparent in the course of the
ensuing specification, are achieved in a portable exercising
apparatus, which in its folded form resembles a chair and may be so
utilized. The apparatus includes: an upright stand member having a
support base, a pair of tubular uprights, a U-frame adjustably
telescoped upon the uprights, and a pair of tubular arm pieces
projecting horizontally from the legs of the U and a three piece
foldable board, one end of which may be engaged with pairs of
supporting hooks on the stand, with the remainder of the board
arranged in accordance with the exercise program then in progress.
The board may be folded and supported from the arm pieces and
uprights to yield the chair-like structure. With the board
disengaged from the stand, the latter may be adjusted in height and
utilized in chinning and lift-off exercises. A pair of tubular
springs and detachable hand pieces are stored in the hollow arm
pieces and are attachable to points of the stand member for use in
various parts of an exercise program. The said board, when
disengaged from the hook pairs, may also be made to overlie
portions of the stand base, and with the user reclining on the
board, various exercises wherein the user interacts with elements
of the stand may be performed.
The previously set forth and other objects, advantages, features
and uses will be apparent during the course of the following
discussion, when taken in conjunction with the accompanying

in the direction of the arrows, showing the storage of the tubular
springs and hand pieces; and
FIG. 15 (on the same sheet as FIG. 11) is an enlarged side detail
view of the joint between the first and second sections of the
support board of the apparatus, viewed in the direction of arrow 15
of FIG. 7.
In the drawings, wherein for the purpose of illustration, there is
shown a preferred embodiment of the invention and wherein like
numerals designate like parts throughout the same: FIGS. 1 and 2
are front and side elevational views respectively of exercising
apparatus 20 of the invention. The views of FIGS. 1 and 2 actually
depict apparatus 20 in its fully folded or storable condition. A
clearer understanding of the component parts may be obtained by
simultaneous examination of the perspective view of FIG. 6, which
shows apparatus 20 in one of its exercising configurations, more
specifically in the arrangement utilized for performance of sit-up
exercises.
As may thus be seen from the three specified figures, apparatus 20
includes, generally, an upright stand member 22 and a foldable
support board 24. Stand member 22 comprises a base 23 including a
pair of tubular support legs 26 and 28 turned down at the forward
ends 30 and 32 thereof to provide additional support during the
exercise functions-- which are generally performed from this side
of stand 22-- and a cross element 34 connecting legs 26 and 28. A
pair of tubular uprights 36 and 38 extend upwardly from the
approximate mid-points of legs 26 and 28. Only the ends of such
uprights are seen in the referenced figures. Their extent may be
seen, for example, in FIG. 8, which will subsequently be referred
to in greater detail.
Telescoped upon uprights 36 and 38 in height-adjustable fashion is
a tubular U-frame 44, comprising vertically disposed legs 40 and 42
and a base portion 46, such base portion 46 con-stituting the upper
boundary of stand 22. A pair of locking means 48 and 50 in the form
of a threaded member passing through each leg of U-frame 44 and a
knob for advancing each member, are provided for locking the
U-frame at a selected height during exercise functions. A pair of
tubular arm pieces 52 and 54 project from U-frame 44. These arm
pieces are, as seen in FIG. 1, instrumental in establishing a
chair-like appearance in the folded apparatus; as will be seen,
they are also utilized in various of the exercises performed on
apparatus 20, and in addition provide a storage function to be
described below. U-frame 44 is provided with pairs of receiving
hooks at 61 and 63 each such pair including two hooks at
corresponding vertical positions on legs 42 and 40. In the
arrangement depicted hook pair 61 is close to the top of frame 44,
with pair 63 below the mid-point of the frame.
Board 24 is comprised of three adjoined sections, namely, a first
section 56, which is somewhat longer (and wider) than second and
third sections 58 and 60. As may be best seen in the plan view of
FIG. 7, each section of board 24 is formed from a pair of parallel
tubular members, such as members 62 and 64 in section 56 and an
overlying pad 66 of fabric or the like, which is secured to the
parallel tubular members by any convenient means, including e.g.,
U-bolts or the like. The end 68 of first section 56 terminating
board 24, is provided with a cross-piece 70 which is joined to
members 62 and 64. This cross piece 70 includes end portions 72 and
74 which extend beyond the sides of board 24 and are receivable in
the hook pairs 61 and 63 at U-frame 44.
The manner in which the several board sections are pivotally
adjoined is best seen in the detailed fragmentary views of FIGS. 3,
4, 5, and 15. In the case of FIGS. 3, 4, and 5, the joint 76
between second section 58 and third section 60 appears in side and
end detail. It is seen that tubular members 78 and 80 of sections
58 and 60 are hinged on a pin 82 so that the board sections may be
folded as in FIGS. 4 and 5 with projection 84 bearing against
member 78; or alternatively the tubular members (and corresponding
board sections) may be aligned as in FIG. 3. It will be noted that
in such aligned position the adjacent ends of members 78 and 80
abut one another, restraining further opening of the associated
sections and providing a rigid structure with respect to a body
overlying the thus adjoined sections (as seen in FIG. 6).
The joint 85 between first and second board sections differs from
joint 76 as is seen in the top detail view of FIG. 15.
In the case of joint 85, the tubular members 64 and 83 of the board
sections overlap somewhat with a fixed bolt 86 passing through the
overlapped pieces and being retained by a fastener 88; and a
removable bolt 90 passing through the overlapped pieces at a point
spaced from fixed bolt 86. The net effect of such arrangement is
that by removing bolt 90, the first and second board sections 56
and 58 are free to fold upon one another, whereas inserting bolt 90
with the sections 56 and 58 aligned provides rigid resistance to
departure of the adjoined sections from their aligned position.
With the aid of the foregoing, the manner in which the present
invention functions to achieve the various useful configurations
may be understood. Thus in FIGS. 1 and 2, it is seen that in the
folded, storable position of apparatus 20, section 56 is folded at
right angles with respect to both section 58 and section 60 which
is folded under section 58. Stand 22 is at its minimum height
(untelescoped) and end portions 72 and 74 are anchored within hook
pair 61 so that section 56 is vertically disposed with pad portion
66 effectively acting as a back rest for an individual wishing to
sit in the "chair" and more specifically, upon pad 66 of section
58.
In order to retain the folded sections 58 and 60 in their shown
positions, a pair of eyes 92 and 94 are provided at the lateral
sides of section 60. These eyes 92 and 94 are engaged by the ends
of a pair of hooks 96 and 98 which depend from a pair of arm covers
100 and 102 and may be swiveled. The latter are simple, generally
tubular elements, closed at one end and flattened somewhat at the
tops 104 and 106, and which slip over arm pieces 52 and 54, and
serve several functions.
First, such covers provide an aesthetic covering to what would
otherwise be bare open ended tubular stock, and thus enhance the
chair-like appearance of apparatus 20 in its folded configuration.
Second, the flattened portions 104 and 106 provide a comfortable
arm-rest when apparatus 20 is used as a chair. Third, as has been
indicated, such covers provide support points for the
aforementioned hooks 96 and 98. Finally, as is best seen in the
cross-section shown in FIG. 14, taken along the line 14--14 of FIG.
1, the covers 100 and 102 both conceal and retain a tubular spring
108 and attached foldable hand piece 110 which are stored within
the tubular arm pieces 52 and 54 when apparatus 20 is folded. These
elements are used in various exercises which may be performed on
the apparatus.
In FIG. 6, which has been referred to heretofore, apparatus 20 is
configured so as to enable a user to perform sit-up exercises. For
such purpose the end portions 72 and 74 of board 24 are engaged
with hook pair 63 at the rear of frame 44 whereby both the hook
pair and legs 42 and 40 of the U firmly anchor board 24 against
slippage. The exercising individual 112 reclines on the rigid board
with his feet preferably anchored by a strap member 114 extending
across section 56 of the board.
In FIG. 8 apparatus 20 is shown in a "chinning" configuration. This
configuration may be compared to FIG. 10, which is generally
similar and shows apparatus 20 in use in the performance of
"lift-off" exercises. In both cases, the stand 22 is seen to be
disassociated from board 24 and U-frame 44 is adjusted in height so
as to permit the individual 112 to engage in the appropriate
exercise.
In FIG. 9 a configuration of apparatus 20 is shown, which permits
the performance of leg pushing exercises. As seen therein, the
board 24 is detached from stand 22 and with section 60 folded under
section 58 but with section 56 extended, the first two sections are
rested upon cross member 34 of stand 23. A tubular spring, as seen
at 108, is stretched between an eyelet 116 provided at the
mid-point of each leg 26 and 28 of the support base, and to the
hook pair 63. With the locking means 48, relaxed, U-frame 44 is
free to telescope upwardly and downwardly on uprights 36 and 38.
The exercise is thus performed by individual 112 reclining upon
board 24 with the small of his back against pad 66 of section 58
and his legs extended so that his feet push against base 46 and the
bias provided by the tubular springs. It should be observed that
with board 24 extended as shown a very firm support against tipping
is provided for stand 22. In effect, a horizontal base extending
all the way from down-turned portions 30 and 32 of legs 26 and 28
to cross member 70 is provided, and it will also be appreciated
that the end portions 72 and 74 of member 70 combine with the
separation of legs 26 and 28 to provide a wide stance resisting
tipping into or out of the plane of the figure.
In FIG. 11 a configuration of apparatus 20 is shown, which is
useful in performing shoulder drawing exercises. The arrangement is
reminiscent of that shown in FIG. 6, except that the board 20 is
now seen to be anchored to the top hook pair 61 and to extend
rearwardly from stand 22 to define therewith a triangular type of
configuration. In the present arrangement, the tubular springs 108
are again secured to the eyelets 116, with the hand pieces 110
however, now being attached to the opposite end of such springs and
grasped by user 112 as he lies on his back on the rigid board 24.
The exercise is then performed by such user drawing on the hand
pieces 110 and or moving them from side to side as suggested by
arrows 118. The hand pieces 110 and tubular springs are, of course,
those same elements as have been discussed in connection with FIG.
14. The hand pieces and springs are detachable from one another as
by means of spring clips or similar devices which are known in the
art.
In FIG. 12, apparatus 20 is shown in a configuration utilized for
performance of over-the-shoulder drawing exercises. In the
arrangement shown therein, board 24 is fully extended and aligned,
with section 56 draped over base portion 23 of the stand for
stabilizing the apparatus. One end of each of the tubular springs
108 is attached to upper hook pair 61 and the user standing upon
board section 58 with his back toward stand 22 then performs the
exercise by drawing hand pieces 110 toward him-- in an over the
shoulder fashion.
Finally, in FIG. 13, a configuration for apparatus 20 is shown
which is useful in performing vertical arm draw exercises. In this
configuration, sections 58 and 60 of board 24 are folded upon
themselves and rest upon the ground, with the cross member 70 of
section 56 resting upon legs 26 and 28 of base portion 23 to
stabilize stand 22. The attachable ends of tubular springs 108 are
secured to a pair of eyelets 120 on cross member 34 of the stand
with hand pieces 110 secured to the opposite ends of the springs.
With board 24 thus extending rearwardly of stand 22, the individual
112 undertaking the exercise stands upon section 56 and repeatedly
draws pieces 110 toward him against the spring bias.
While the present invention has been particularly described in
terms of a specific embodiment thereof, it is apparent to those
skilled in the art that numerous modifications are possible without
departing from the spirit of the invention and the scope of the
subjoined claims.
