Cl. 272-58 6 Claims ABSTRACT OF THE DISCLOSURE A folding portable case, suitcase or the like which may be opened to fold out a three-section exercise board disposable in a plurality of different positions in extension beyond the original dimensions of the unit for providing substantially all configurations employed in physical culture exercises. Spring loaded cables provide for all types of lifting, pulling and pushing exercises so that complete weight reduction and body building exercises are capable of being performed on a single portable unit.
BACKGROUND OF INVENTION There have been devised a wide variety of different physical exercises for improving the condition of the human body and there exist many professional gymnasiums for use by persons interested in weight reduction or the more general field of physical culture. Such gymnasiums or salons, as they are often termed, usually provide a wide variety of different devices and mechanisms particularly adapted for use in a multiplicity of different exercises scientifically determined to produce particular results. Such professional installations are quite costly to construct and maintain and consequently normally charge a fee for their use. Increased understanding of body needs has also given rise to the development of a variety of different home exercisers or devices and mechanisms which may be privately purchased and employed in the home or thelike for carrying out particular exercises. As an example of the latter are to be found stationary bicycles, bar bells and dynamic tension devices.
Along the line of what may be termed home exercisers there have been developed a variety of different devices which are adapted to be folded into relatively compact form and unfolded to provide particular exercising capabilities. An early example of a body exerciser is illustrated in US. Patent No. 992,272 and subsequent improvements in this general field are found in a wide variety of patents such as, for example, US. Patent No. 2,219,219 and more recent Patents 2,682,402 and 3,295,847. At least certain of these patented devices are particularly designed for folding into a carrying case so as to be truly portable.
One of the major difficulties in the field of what may be termed home exercisers is the inherent limitation of each to a few possible exercises that may be carried out therewith. Furthermore there is normally encountered difiiculties of bulk and weight in any type of attempted portable or home exerciser which seriously limits the capabilities thereof.
There is provided by the present invention a truly portable gymnasium or exercising unit which may take the form of a relatively conventional suitcase, for example, so as to be manually carried from place to place without difiiculty. There is furthermore provided in the present invention the capability of carrying out substantially all exercises possible in a fully fitted gymnasium. The present invention thus overcomes many of the difiiculties and limitations of the prior art and in fact extends the art well beyond the capabilities of prior art devices or mechanisms.
3,664,666 Patented May 23, 1972 ice SUMMARY OF INVENTION The present invention comprises a folding case somewhat in the form of a suitcase within which there is disposed a three-segment padded board adapted to be unfolded from the case when same is open to provide a plurality of different physical configurations for exercise. These three boards are adapted, for example, to provide a sit-up board, a prone or supine bench or an incline bench. There is also provided within the folding case of the present invention one or more spring loaded cable devices having two cables extending therefrom so as to, in combination with the above-noted boards or benches, provide a leg extension machine, a leg-curl machine, a wall pulley and the equivalent of bar bells and dumb bells. Additionally there is provided within the folding case or suitcase what is generally termed a hip roller device and controls are provided for utilization of the internal elements of the present invention for isometric exercises. Pivotally mounted pulley wheels within the device are so arranged that the spring loaded cables may be employed for a wide variety of diiferent exercises and also particularly designed and mounted braces, including a telescopic stand, are provided to ensure full rigidity and complete support for all elements of the present invention when employed for exercising.

DESCRIPTION OF PREFERRED EMBODIMENT The present invention is externally comprised as a folding case or suitcase 11 as illustrated in FIG. 1. A handle 12 may be provided for carrying the case about and latches 16 may be attached to the case for maintaining same in closed position during transport. The case is formed of two major portions which may be termed housings L6 and 17 of like dimensions connected together by an elongated hinge 18 so that the unit or case may be folded open as illustrated in FIG. 2. The central area of the surface of the housing 16 is formed of a board 19 pivotally mounted by means of an elongated hinge 21 on the underside thereof so that the board may be pivoted upwardly from the surface of the housing. The board 19 has the end thereof opposite hinge 21 connected to the center hinge 18. The central area from one side to the other of the housing 17 is also formed as a pivotally mounted board 22 connected to the center portion of the hinge 18. As a practical matter this hinge 18 is normally formed as three axially aligned hinges as indicated in FIG. 2. A further, and important, portion of the present invention is a third board 2 3 shown in FIGS. 4 and 5 and which is pivotally connected by a hinge 24 to the outer or otherwise free end of the board 22. This board 23 is adapted to be folded underneath the board 22 by mounting the hinge 24 on the underside of the boards 22 and 23 and, by having substantially the same length as the board 22, then fits within the housing 17 when the unit is folded together.
With the arrangement described above there may be provided a wide variety of different gymnasium elements for physical exercise. The invention provides for a maximum number of different possible exercises with a single compact unit and to this end there is included a retractable hip roller 26 normally stored in a compartment 27 of the housing 16. These individual rollers are connected together by flexible cords with one end of the combination being connected as by means of a spiral spring 28 to an axle 29 in the compartment 27. An opening 31 in the upper surface of the housing 16 provides for withdrawing the hip rollers from the compartment -27 and extending them laterally across the upper surface of the housing over the top of the board 19 for engagement with hook means 32. Thus the hip rollers are in fact retractable to be normally stored entirely within the compartment 27 but are readily withdrawn therefrom for extension across the board 19 to be used by a person in a conventional manner of using hip rollers. Release of the roller combination from the hook means 312 then results in the rollers being wound back into the compartment 27 for storage.
Within the housing 17 of the case there is mounted one or more adjustably retractable pulleys 36 having two cables 37 and 38 extending therefrom and upwardly through the upper surface of the housing 17 on opposite sides of the board 22 thereof. This pulley 36 may be of conventional spring loaded type from which a cable or two cables may be withdrawn against spring tension. The pulley is capable of adjustment as by means of a handle 39 which may be rotated to tighten or loosen the tension of the spring loading of the pulley. Rings or handgrips 41 and 42 are removably attached to the ends'of the cables 37 and 38 respectively atop the housing 17 so that a person may grip these rings in the performance of various exercises on the gymnasium 0f the present invention. 'There is also provided in the housing 17 a pair of retractable handles 43 and 44 which may telescope into the opposite sides of the housing as illustrated for latching therein until it is desired to extend them for use.
The cables 37 and 38 may also be extended longitudinally of the housing 17 and the housing 16 to wrap about pivotally mounted pulleys 46 and 47. These pulleys 46 and 47 are similarly mounted and referring to FIG. 6 there is shown the pulley 47 mounted on a. hinge 48 so as to be pivotal into an opening 4 9 in the upper surfaceof the housing 16. Thus the pulleys may be pivoted out of the way for storage and yet swung upwardly to have the cables extended thereabout for particular exercises, on the gymnasium of the present invention.
Considering now briefly at least certain exercises that may be performed on the present invention and various configurations of the present invention that are possible with the above described elements thereof; reference is made to FIG. 4 illustrating the first board 19 as being pivoted upwardly and at an angle and the boards 22 and 23 extending in a plane therefrom to thereby define what is generally termed a sit' 'up board. In order to provide support for this sit-up board or slant board, there is provided one or more telescopic legs or stands 51 adapted to be connected to the outer end .of the board 23 and extending downwardly therefrom for engagement with the floor or the like upon which the gymnasium is to be employed. The leg or legs 51 may be formed as a pair of telescopic cylinders with latching means such as a mating pin and holes for maintaining the leg or legs in a desired extended position. i
There is also providedone or more first braces 52 pivotally mounted with in the housing 17 so as to be capable of swinging upwardly to engage the incline board beneath the hinge 18 connecting boards 19 and 22. Second brace or braces'53 are pivotally mounted in the housing 17 adjacent the outer edge thereof for extension upwardly to engage the underside of the incline board in the vicinity of the connection of boards 22 and 23. The arrangements of boards 19, 22 and 23 as an inclined sit-up boardor slant board, as illustrated in FIG. 4, will thus be seen to providea solid unit upon which a person 'maylie for v performing exercises. In this respect there mayflalso be provided angle braces 54 extending from the leg or legs 51 to the underside of theboard '23 for further bracing of the structure. Such angle braces 54' are preferably formed of adjustable length and may be detachably engaged with a board 23 while being pivotally mounted on the leg 51 so as to swing out of the way when the unit is folded into the housing. Note that connections of braces 51, 53 and 54 to the underside of board 23 are either inset or indentations are formed in the underside of board 22 to receive any protruding connections.
One or more foot straps 56 are connected across the outer end of the board 23 so that a person may slip their feet under the straps for carrying out exercises such as, for example, sit-ups as generally indicated by the dashed position of the upper torso of the man shownon the incline bench. Arm exercises may alsobe carried out on the situp board by a person laying thereon gripping the rings 41 and 42 attached to the cables 37 and 38 and pulling upon these rings against the tensionof the pulley 36. Among the other exercises that can be carried out on the in clined board of FIG. 4 areleg extensions wherein the person lies face down On the board with hish'e'ad at. the upper end thereof and places his feetthrough "the rings connected to cables extending about the pulleys 46 and 47 7 so as to attempt to bend his legs against the tension of the pulley 36, and also leg curls. A slant boardor sit-up board is well known in the field of physical culture and thus no attempt is made here to identify all possible exercises that may be performed thereon. There may also be provided a vibrator detachably mounted to the underside of board 22 for massage purposes.
There is illustrated in FIG. 5 an alternative folded configuration of the present inwention. In this position the first board 19 remains fiat upon the housing 16 while the board '22 is folded upwardly at an angle to form an incline bench and the board 23 is'extended horizontally to forma'supine bench or, as it is more'commonly termed, a prone bench. It will be seen that in the configuration of FIG. 5 the leg 51 is telescoped'to somewhat shorter length than in the illustration of FIG. '4. Furthermore the second brace 53 is pivoted slightly forward in order to engage the upper end of'the board 22 to provide full support for the incline bench and prone bench. Various exercises are possible upon th einvention as folded in the configura1 tion of FIG. 5. Some possible exercies are illustrated in FIGS. Sand 7 and others will be apparent to those knowledgeable inthe field of physical culture. f i
The invention furthermore provides a bar 61having revolving pulley hooks 62mounted adjacent opposite ends thereof for connection to the cables 37 and 38 in place of the rings or grips 41 and 42. This bar may then be employed as a bar bell for various different positions of weight lifting as, for example, on the prone bench of the present invention. The pulley hooks are mounted for rotation about the bar 61 as, for example, on ball bearings or the like, so that one exercising with the bar connected to the cables employs the full equivalent of a bar bell with weight determined by the setting of the pulley 36.
There is illustrated in FIGS. 4 and 5 of the drawings a thin mat 71 placed upon the upper surfaces of the boards 19, 22 and 23 for comfort of one exercising upon the present invention. This mat and possibly certain other portions of the invention such as, for example, the leg or legs 51 are stored within the folding case as, for example, in a storage compartment 72 formed in the outer portion of the housing 16. The top 73 of the compartment is mounted by a hinge 74 at the outer edge of the housing 16 so as to be pivotable upwardly for access to the interior of the storage compartment With regard to folding of the present inventfon into portable form, it is noted that with the braces 52 and 53 folded into the housing 17 and the leg or legs 51 removed from engagement with the board 23, this latter board is then swung about the hinge 24 beneath the board 22 until the two are in parallel abutting relationship over their respective length. This is actually accomplished by first swinging the board 19 down into the housing 16 to form a portion of the upper surface thereof and then pivoting the board 22 upwardly from the hinge 18 so that the two boards 22 and 23 may be folded together. The combination is then folded downwardly into the housing 17 with the board 22 then forming a part of the upper surface of the housing. The pulleys 46 and 47 are pivoted downwardly into the openings in the upper portion of the housing 16 and the rings 41 and 42 are disconnected from the cables which then retract until the cable ends are arrested by the openings through the top of the housing 17. With the hip roll mechanism stored in the compartment 27 the two housings 16 and 17 are then folded together along the hinge 18 to close the suitcase 11 as illustrated in FIG. 1. The handles 43 and 44 fit flush with the exterior sides of the housing 17 when they are telescoped inwardly and thus the entire invention presents the appearance of a suitcase or the like, so as to be readily carried about or stored.
Substantially every exercise normally carried out in a fully equipped gymnasium may be performed upon the portable gymnasium of the present invention. At least certain of these exercises have been briefly described or noted above. However, it is not intended to list all possible exercises capable of beingaccomplished with the present invention. It is, however, noted that isometric exercises are possible by providing a lock on the tension cable pulley 36 so that the cables may be extended to some desired length for a particular position of the person and then will move no further.
With regard to materials of construction, it is noted that the housings and folding exercise boards may be formed of any lightweight rigid material having sufficient structural strength to support the weights and forces to be applied thereto. Certain types of Fiberglas structures may be employed for at least part of the construction and laminated structures are also suitable. Although certain elements of the invention have been identified as boards, this is not intended to define them as being formed of wood, although this is possible, but instead the terminology is related to the use.
There has been described above an improved portable gymnasium having wide capability and many practical applications. It is not intended to limit the present invention to details of the description or illustrations for it will be understood by those skilled in the art that numerous modifications and variations are possible within the scope of the invention.
