COLLAPSIBLE PORTABLE EXERCISING MACHINE This invention relates to a collapsible portable exercising machine in which the user can extend himself horizontally and be held suspended for twisting movement of the body while grasping handle bars vertically spaced from one another on the vertical frame support.

It is an object of the present invention to provide a hammock type exercising machine in which the frames of the machine consist of an assembly of U-shaped members to thereby make possible a machine which can be readily assembled without putting parts together but merely with the extending of the frame assemblies so that they span the bottom of the machine for support upon a floor surface.

It is another object of the invention to provide a portable exercising machine in which the frame assemblies are hinged upon one another and wherein the frames can be adjusted to adapt the machine to users of different lengths.

It is still another object of the invention to provide an exercising machine formed of U-shaped frame members which can be collapsed upon one another for the adapting of the machine for purposes of transport or storage and readily extended when the machine is to be set up at a new location and wherein the brace and the vertical frame are held separate from one another by simple collapsible brackets extending between the lower ends of the frame members and wherein wheeled supports are provided on one of the frame members for the removal of the collapsed machine to a new location by pivoting the machine onto the wheels and the collapsed machine moved in wheel-barrow like fashion.

Other objects of the invention are to provide a collapsible portable exercising machine adapted for use by a user when extended in a horizontal position and including pivotable foot supports, which, having the above objects in mind, is of simple construction, has a minimum number of parts, easy to initially assemble, easy to collapse for transport, durable, light in weight, of pleasing appearance, efficient and effective in use.

For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawings in which:

FIG. 1 is a side elevational view of the exercising machine formed of U-shaped vertical and bracing members and embodying the features of the present invention, the machine being erected for use.

FIG. 2 is a top plan view of the exercising machine.

FIG. 3 is a fragmentary perspective view of one of the hinge bracket fittings fixed to the vertical members to hingedly support the hammock pivot frame on the outer end of which the foot grip support is pivotally mounted.

FIG. 4 is a fragmentary side elevational view of a latch pin used for securing the U-shaped brace members telescoped one from the other.

FIG. 5 is a transverse sectional view of the latch pin assembly shown in FIG. 4 and as viewed on line 55 thereof.

FIG. 6 is a side elevational view of the exercising machine collapsed vertically preparatory to being transported on its wheels.

FIG. 7 is a fragmentary rear elevational view of the exercising machine looking in elevation generally upon the U-shaped vertical support member and upon the handle bars that are gripped by the user of the machine when performing the exercise.

FIG. 8 shows handle bars adjustable upon the vertical support member legs to different pin hole elevations thereon.

FIG. 9 is a fragmentary vertical sectional view of the handle bar pin lock mounting assembly as used on line 9-9 of FIG. 8.

FIG. 10 is a plan view taken of the outer end of the U-shaped frame member of the hammock supporting frame assembly with a bicycle type foot supporting apparatus pivoted upon the bight end of the support member and with pedals arranged in crank fashion.

FIG. 1 l is a top and side perspective view of the exercising machine showing all of the U-shaped frame members in full and with the machine set up fully for receiving the user of the machine.

Referring now to the Figures, 15 represents the main vertical support formed of tubing and bent into U- shape to provide for a top bight portion 16 and

side legs

17 and 18 that respectively have

foot plates

19 and 21 at their lower end on which the vertical support 15 is rested when the machine is set up for use. The vertical support 15 can be formed by a simple bending procedure.

l-Iingedly connected to the bight portion 16 of the vertical support 15 by

spaced hinges

22 and 23 is a telescoping brace assembly 24 comprising two upper and lower

U-shaped telescoping members

25 and 26 which are axially adjustable one with another to either set up the assembly 24 for effecting the raising of the vertical support in a vertically extending position or for the collapse of the parts when the brace assembly 24 is being hinged so that the same can be moved to a position vertically overlying the vertical support 15 so that the machine can consume little space and at times of transport of the machine.

The upper telescoping brace member 25 is formed of a rod bent into U-shape by the usual bending procedure and has a bight portion 27 connected by the

hinges

22 and 23 to the bight portion 16 of the vertical support 15 and which is of equal width to the bight portion 16 thereof.

Legs

28 and 29 descend from the bight portion 27 and are interfitted for telescoping movement within upwardly extending

legs

31 and 32 of the lower U- shaped member 26 having a bight portion 33 that will rest on the floor when the machine is set up for use to brace the main vertical frame support 15. On the upper ends of the legs of tubular lower brace member 26 are respectively

pin lock assemblies

33 and 34 adapted to enter

pin receiving holes

35 and 36 of the

respective legs

28 and 29 of the upper U-shaped member 25 of the brace assembly 24. These

pinlatch assemblies

33 and 34 are shown more in detail in FIGS. 4 and 5. They include a pin 37 having a hand knob 38 mounted on a raised outer end of a spring mounting member 39 welded at 41 to the outer surface of

leg

31 or 32. The

legs

31 and 32 have a hole 42 for accommodating the pin 37 which hole can be aligned with one of the adjusting

holes

35 or 36 of the

leg

28 or 29 respectively of the upper brace member 25.

When it is desired to collapse the apparatus to conserve space and for purposes of transport the pins 37 of the

pin assemblies

33 and 34 are simply pulled to allow the

legs

28 and 29 of the upper U-shaped member 25 to be lowered into the

respective legs

31 and 32 of the lower U-shaped member 26.

At each side of the lower U-shaped member at the respective opposite end of the bight portion 33 are mounted

wheel brackets

44 and 45 carrying respectively

wheels

46 and 47. These brackets and wheels extend normally when the exercising machine is set up for use as shown in FIGS. 1 and 2 extend rearwardly and out of contact with the floor but when the machine is collapsed in a manner to be made more clear as is shown in FIG. 6 so that the brace frame assembly 24 is col lapsed onto the vertical support as shown in FIG. 6, the

wheels

46 and 47 may contact the floor so that upon the machine being tilted downwardly from its upper end portions the same may be supported in wheel barrow fashion upon the floor to allow the machine to be easily transported to a new location. This is all effected without any detailed disassembling of any of the parts.

In order that the brace assembly 24 can be held in its outwardly extended position from the vertical frame support 15 at times when the machine is being used,

collapsible brace assemblies

48 and 49 extend between the vertical frame and the brace assembly at their lower ends and can be collapsed upwardly as illustrated in FIG. 6 by their respective hinge connections 51 and their pivotal connections respectively at their ends with the side legs of frame support and the brace assembly as indicated respectively at 52 and 53. When the

collapsible braces

48 and 49 are lifted as best shown in FIGS. 6, the lower end of the brace assembly 24 can be joined or made to overlie the lower end of the vertical frame support 15. Thus again by merely pulling the

pin assemblies

33 and 34 of the brace assembly 24 and lifting the

collapsible brackets

48 and 49 the brace 24 can be collapsed onto the vertical support 15 Mounted respectively on the

legs

17 and 18 of the vertical support frame 15 and intermediate the height thereof are respectively

pivot brackets

56 and 57 as best shown in FIG. 3 and to which are respectively pivotally connected the ends of

tubular sleeves

58 and 59 by

respective pivot pins

61 and 62. Telescopically fitted into the free ends of the

sleeves

58 and 59 are

respective legs

63 and 64 joined by a bight portion 65 to provide a U-shaped member which when taken with the

sleeves

58 and 59 provides for a hammock frame assembly which may be indicated generally at 66 that is vertically adjustable within the brace frame assembly 24 and through the

brackets

56 and 57 upon the vertical frame support 15. This vertical adjustment of the hammock frame 66 is effected by means ofa winch 68 operated by a hand crank 69 easily accessible to the user of the exercising machine when stretched horizontally within the hammock frame assembly 66 at the opposite side of the machine. As the crank 69 is turned one way to the other, the hammock frame assembly 66 can be lifted or lowered at the will of the user and who will be lying in a hammock fabric 76 loosely stretched and so as to cradle between the

sleeves

58 and 59 and with its ends looped and sleeved onto the

sleeves

58 and 59 to thereby provide a vertical connection of the hammock therebetween so that considerable weight may be supported by the hammock fabric 76. The

legs

63 and 64 of the U-shaped frame member have respec tively adjusting holes 63' and 64 into which pin assemblies 77 and 78 constructed similar to the

pin assemblies

33 and 34 may be extended to hold the U-shaped frame in its adjusted position with its legs telescoped in or out of the

sleeves

58 and 59. The adjustment is made to adapt the hammock and frame assembly for persons of different height.

On the bight portion 65 of the U-shaped frame member a sleeve 81 is rigidly connected to extend axially and longitudinally with the hammock frame 66. A T-shaped foot support member 82 is journaled by its stem 83 in the sleeve 81 and on the outer ends are mounted

foot supports

84 and 85 into which the users feet are extended when lying in the hammock 76.

In order that the user can hold himself out of the hammock 76 while his feet are being supported in the

supports

84 and 85, vertically spaced

handle bars

87 and 88 are adjustably secured between the

legs

17 and 18 of the vertical frame support 15. The distance between the

handle bars

87 and 88 will be equal to the spance of the arms of the user extended outwardly from the shoulders. With the arms so gripping the

handle bars

87 and 88 and with the body of the user out of the hammock 76 and his feet in place in the foot grip supports 84 and 85 the user can twist and turn to work the various muscles of the body to particularly exercise the legs and torso muscles as well as the shoulder and arm muscles. The body is lifted clear of the hammock and the muscles of the body must support the full weight of the users body against the pull of gravity. When the exercise is complete or the user desires a rest, he may drop onto the hammock 76. While on the hammock with the hands made free of the

handle bars

87 and 88 the user may turn the crank 69 of the winch 68 to raise or lower the hammock frame support assembly 66 and if lowered to the full extent the user can leave the hammock with the feet having been taken from the foot supports 84 and 85 and dropped to the floor and the body positioned by the lowering of the hammock frame 66 to nearly a vertical position so that the user can slide out of the forward end of the hammock 7 6.

The

handle bars

87 and 88 are connected at their ends to the

legs

17 and 18 of the vertical support frame 15 by respective

pin latch devices

89 and 91 for the

handle bar

87 and 92 and 93 for the upper handle bar 88. One of these spring latch devices will be described which will suffice for a description of all of the devices. The spring latch device 92 is shown in detail in FIGS. 8 and 9 and comprises a cradle like fitting member 94 that is slidable upon the legs 17 and on which there is provided a spring leaf 95 that has a latch pin 96 that overlies the lower end of the member 94 and can be extended into any one of several adjusting holes 96' in the vertical legs 17. The handle bar 88 has an internal metal tube 97 on which a rubber grip sleeve 98 is fixed. Extending outwardly from the end of the tube 97 is a pivot fitting 99 that is journaled in the cradle like member 94. By lifting the spring latch 95 and withdrawing the pin 96 from the pin holes 96' the

handle bar

88 or 87 can be adjusted vertically, the spring latch 93 of the opposite assembly being lifted simultaneously so as to free both ends of the

handle bar

87 or 88 at the same time.

In FIG. 10 there is shown a pedal crank assembly 101 that can replace the foot rest assembly 82 so that the feet of the user may be supported in a bicycle crank manner to permit the legs to be worked like on a bicycle while lying in the hammock 76 and at the same time permit the user to bicycle while lifting his body from the hammock 76. This bicycle crank has oppositely extending crank

arms

102 and 103 which respectively have pivotal foot grips 104 and 105 on their outer ends. The crank 101 is joumaled in a T fitting 106 carried on a stem 107 that is journaled into sleeve 81 fixed to the bight portion 65 of between

legs

63 and 64 of the outer U-shaped member of the hammock frame assembly 66.

The user of the machine can use the hammock 76 while resting between exercises. The user of the machine can exercise as vigorously or mildly as he wishes. The arms, legs, shoulders, back and neck muscles will be gradually developed and strengthened by the use of the machine.

When the machine is not to be used it can be easily collapsed as above described and transported on its

wheels

46 and 47 to another location or to a storage space. By the provision of the use of U-shaped members the cost of producing this machine has been greatly reduced and at the same time permits the machine to be a portable one and one which can be collapsed and easily rearranged for use without need for disassembling members or assembling the members when the machine is to be put into use. A minimum number of parts has thus been provided for the manufacture of this type of exercising machine to make for an original and easy assembling of the parts and to provide parts which permit for the adjustment of the parts to adapt the machine to the users height.
