DETAILED DESCRIPTION OF THE INVENTION

(14) FIG. 1 shows in a symbolic and exemplary as well as perspective overall view, a first embodiment of an universal fitness device 100 according to the invention. A front pair of limbs vSp is formed by a left front limb 1a and a right front limb 1b, and a rear pair of limbs hSp is formed by a left rear limb 2a and a right rear limb 2b. The front pair of limbs vSp and the rear pair of limbs hSp are connected by means of a double joint 200 in that a connecting or horizontal bar 4 is passed through merely indicated fitting bore holes 27a and 27b in an upper end area oEb of the limbs 2a and 1a as well as 1b and 2b, thus forming a first, left connecting joint 3a and a second, right connecting joint 3b. The upper ends of the limbs 2a and 1a as well as 1b and 2b are held together by positioning rings 5a-5d arranged on the connecting or horizontal bar 4, whereby, in this perspective view, only the positioning rings 5a and 5c are visible.

(15) In the front pair of limbs vSp, holders or recesses 6a-6l are arranged at regular intervals, for example for a barbell 300, which is suspended by a barbell bar 24, for example in the holders or recesses 6e and 6f. The barbell 300 furthermore has weights or pairs of weights 25a and 25b, each of which is fixed by a star ring 26.

(16) Also arranged at regular intervals, but offset from the holders or recesses 6a-6l, are bore holes or receptacles 7a-7n in the front limbs 1a and 1b, which form the front pair of limbs vSp. Additional bars 8, for example, are insertable into these bore holes or receptacles 7a-7n at any height, as shown by way of example, in the bore holes or receptacles 7i and 7j.

(17) Similar to a trestle or stepladder, the front limb 1a and the rear limb 2a as well as the front limb 1b and the rear limb 2b are each stabilized or fixed against further spreading by a fixing holder 9a and 9b. Due to a predefined length of the fixing holders 9a and 9b as well as their fixed arrangement, preferably in a lower end area uEb in a respective mounting position Mp, as illustrated, a predefined operating position Bp of the universal fitness device 100 results, with a likewise predefined spread angle Sw between the front limbs 1a or 1b and the rear limbs 2a or 2b, respectively.

(18) Furthermore, is still evidently in this FIG. 1 that a reinforcing board or step board 10 is arranged at the rear side of the rear limbs 2a and 2b. As already mentioned, it can also be box-shaped and have a large-surface upper side 28, which optionally can also be aligned approximately horizontally.

(19) In the illustrated first embodiment of an universal fitness device 100 according to the invention, the two front limbs 1a and 1b and the two rear limbs 2a and 2b are arranged at the top of the connecting joints 3a and 3b such that the rear limbs 2a and 2b are on the outside and the front limbs 1a and 1b are on the inside. This arrangement can also be reversed or mixed, but it is considered advantageous if the somewhat heavier rear limbs 2a and 2b are arranged on the outside as far as possible and in this way give the universal fitness device 100 a little more stability.

(20) In FIG. 2, the first embodiment of an universal fitness device 100 according to the invention from FIG. 1 is shown from a straight and rear view. The elements shown are all already known, except for the positioning rings 5b and 5d, which are now also evident.

(21) FIG. 3 shows a second embodiment of an universal fitness device 100a according to the invention in a detail view, representing merely an upper end area oEb.sub.1 of a first front limb 1c and a first rear limb 2c, and a second front limb 1d and a second rear limb 2d. The two first limbs 1c and 2c are again arranged in a first connecting joint 3c by means of a connecting or horizontal bar 4a, and the two second limbs 1d and 2d are correspondingly arranged in a second connecting joint 3d. The two connecting joints 3c and 3d in turn form a double joint 200a and the front limbs 1c and 1d form a front pair of limbs vSp.sub.1 and the rear limbs 2c and 2d form a rear pair of limbs hSp.sub.1. The front limbs 1c and 1d each form a spread angle Sw.sub.1 with respect to the rear limbs 2c and 2d, and this in turn results in an operating position Bp.sub.1 of the universal fitness device 100a.

(22) Furthermore, is evidently that the first connecting joint 3c and the second connecting joint 3d are formed in that the limbs 1c, 2c and 1d, 2d are fixed to the connecting or horizontal bar 4a by means of positioning rings 5e-5h. The positioning rings 5e and 5g are merely indicated here by curved arrows, because they are hidden in this view. On the other hand, it is clearly visible that the positioning ring 5h is fixed to the connecting or horizontal bar 4a by means of a grub screw 11.

(23) Furthermore it is recognizable how the connecting joint 3d is constructed, namely the connecting or horizontal bar 4a is inserted into a fitting bore hole 27c in the front limb 1d and simultaneously into a fitting bore hole 27d in the rear limb 2d. Moreover, in this embodiment of a fitness device 100a according to the invention, a lock 400 is implemented in that a bolt or locking pin 13 with a knob 14 is inserted into a radial bore hole 12 in the connecting or horizontal bar 4a and into corresponding bore holes, not represented in detail, radially arranged with respect to the fitting bore hole 27c in the upper end area oEb.sub.1 of the front limb 1d. The connecting or horizontal bar 4a is in this way secured and can no longer turn in a rotation R.

(24) Furthermore, in this FIG. 3 is still recognizable how bore holes or receptacles 7o and 7p are arranged, by way of example, in the front limbs 1c and 1d, for receiving additional bars 8, as shown in the previous FIGS. 1 and 2.

(25) In FIG. 4, a fourth embodiment of a fitness device 100b still according to the invention is shown symbolically and by means of a detail drawing. This embodiment is characterized on the one hand by a lock 400a, which this time is provided for securing against radial turn in a rotation R.sub.1, but also against axial displacement of an additional bar 8a, which is again inserted by way of example in a bore hole or receptacle 7q in a front limb 1e. The additional bar 8a has a radial bore hole 12a through which, but also through corresponding bore holes not represented in more detail in the material of the front limb 1e, a bolt or locking pin 13a with a knob 14a is inserted.

(26) Apart from that, the front limb 1e has holders 6m-6p and further bore holes or receptacles 7r-7t as previously described, for receiving the additional bar 8a in a different position or for receiving further additional bars. Incidentally, a hachure S symbolically represents that a preferred material for manufacturing the front limb 1e and the universal fitness device 100b in general is wood, again preferably laminated wood and still preferably boiler impregnated wood.

(27) Moreover, the front limb 1e also has a threaded bushing 17 so that a fixing holder 9c, rotatable arranged in a swivel joint 15 preferably in a lower end area uEb.sub.1, is pivotable upward so that a hand screw 16 is screwable into the threaded bushing 17. In this way, the fixing holder 9c is pivotable from a mounting position Mp.sub.1, in which it limits a spread angle Sw.sub.2 and an operating position Bp.sub.2 of the universal fitness device 100b, to a stand-by or waiting position Wp, in which the universal fitness device 100b is collapsed as a whole. This will be shown later in FIG. 9.

(28) FIG. 5 shows, in a merely symbolic detail drawing, a fourth embodiment of an universal fitness device 100c, which is still in accordance with the invention and which is characterized in that a rubber cap 18 is arranged, by way of example, in a lower end area uEb.sub.2 of a front limb 1f.

(29) Apart from that are shown known features, such as a holder or recess 6q, a bore hole or receptacle 7u, and a fixing holder 9d that is pivotable disposed in a swivel joint 15a, as in the previous embodiment shown in FIG. 4. The shown position or orientation of the fixing holder 9d corresponds to a mounting position Mp.sub.2, and this in turn gives a spread angle Sw.sub.3 as well as an operating position Bp.sub.3 of the universal fitness device 100c.

(30) In FIG. 6 is merely symbolic and schematic and in a detail drawing represented, a fifth embodiment of a fitness device 100d, which is still according to the invention, which is characterized by a variable fixing possibility of the spreading of the limbs. For this purpose, a first threaded bushing 17a, which is merely indicated by an arrow, is arranged on a rear limb 2e, into which a hand screw 16a is screwed and thus a fixing holder 9e lock it off in the widest spread position. Above the merely indicated threaded bushing 17a, however, further threaded bushings 17b and 17c are also arranged, which result in less wide spreads. In any case, the shown mounting of the fixing holder 9e in a lower end area uEb.sub.3 in a mounting position Mp.sub.3 in the threaded bushing 17a results in a spread angle Sw.sub.4, as well as an operating position Bp.sub.4 of the universal fitness device 100d. The mountings of the fixing holder 9e in the threaded bushing 17b or 17c would each result in slightly different spread angles Sw.sub.4 as well as slightly different operating positions Bp.sub.4 of the universal fitness device 100d.

(31) FIG. 7 shows, again in a merely symbolic and exemplary detail view from the rear, a sixth embodiment of an universal fitness device 100e still according to the invention. Two rear limbs 2f and 2g form a rear pair of limbs hSp.sub.2 and this is fixed by fixing holders 9f and 9g in a respective mounting position Mp.sub.4 to a front pair of limbs vSp.sub.2, which in turn is formed from front limb 1g and 1h. All this results in an operating position Bp.sub.5 of the universal fitness device 100e at spread angles Sw.sub.5 between the rear limb 2f and the front limb 1g, and the rear limb 2g and the front limb 1h. A reinforcement board or step board 10b connects the two rear limbs 2f and 2g in a lower end area uEb.sub.4 and optionally has a hole 19 arranged approximately central, for example in order to be able to pass through or tie on a rubber band or so-called Thera-Band. An upper side 28a of the reinforcement board or step board 10b can again also be formed approximately horizontal and wider.

(32) In addition, but useful just for example for rowing or pulling exercises with the Thera-Band or else also for an improved support position of the universal fitness device 100e against a wall, for example during step exercises on or against the step board 10b, flattenings 21a and 21b are provided at the front sides of the frontin this view rearlimbs 1g and 1h, respectively.

(33) Also optionally arranged in the lower end area uEb.sub.4 of the rear, now front, limbs 2f and 2g are respective rollers 20a and 20b. These serve the purpose of being able to tilt and roll away the universal fitness device 100e.

(34) FIG. 8 shows, again only in an exemplary detail drawing, a seventh embodiment of an universal fitness device 100f still according to the invention, which is characterized in that felt gliders 22a and 22b are arranged in a lower end area uEb.sub.5 of a rear limb 2h.

(35) Apart from that, a roller 20c is now readily visible in use in that the universal fitness device 100f has been tilted onto its rear limbs 2h and virtually rests thereon. For this purpose, the diameter of the roller 20c preferably exceeds the final dimension of a reinforcement board or step board 10c. It should be imagined that, in the indicated recumbent position of the universal fitness device 100f as indicated herein, the front limbs still project upward at a spread angle Sw.sub.6 because a fixing holder 9h is still screwed to a hand screw 16b in a mounting position Mp.sub.5 and has not yet pivoted to the waiting position on the opposite front limb. In other words, the universal fitness device 100f is in a recumbent position but still in an operating position Bp.sub.6.

(36) FIG. 9 shows an eighth and final embodiment of a fitness device 100g still according to the invention, which is represented folded and lying in a top view in a folding position Kp. Thus, not only front limbs 1i and 1j, but also rear limbs 2i and 2j are in the same plane, likewise as fixing holders 9i and 9j, which are now in respective waiting positions Wp.sub.1 and Wp.sub.2. A spread angle Sw.sub.7, between the rear limbs 2i and 2j and the front limbs 1i and 1j, is zero.

(37) In a lower end area uEb.sub.6, flattenings 21c and 21d are now visible from the front, at the front and inner limbs 1i and 1j at their end faces. Also there, and merely indicated by curved arrows, are rollers 20d and 20e on the rear limbs 2i and 2j. An auxiliary bar 8b is inserted into merely indicated receptacles 7v and 7w. Otherwise, the universal fitness device 100g has the previously known features and thus these are merely represented consecutively numbered in this FIG. 9 without further description.

(38) However, a still according to the invention and optional to all previous embodiments of an universal fitness device 100, 100a-100f according to the invention from the previous FIGS. 1-8, is that recesses 23a-23l are also arranged in the rear limbs 2i and 2j at the level of holders 6r-6? in the front limbs 1i and 1j. These recesses 23a-23l result in the possibility of leaving a barbell 300a supplied in the universal fitness device 100g even in the folded folding position Kp of the universal fitness device 100g, for example in the holders 6t and 6u in which it is currently located. This is because it would be impractical if the universal fitness device 100g could be folded up and thus stored in a space-saving manner, but for this purpose, the barbell 300a had to be removed beforehand from its holders 6t and 6u, in order to be stored in another, separate location.

(39) In the FIGS. 10A-10L, schematic and exemplary possible fitness exercises are shown, which are feasible with an universal fitness device according to the invention as disclosed in the previous FIGS. 1-9. Such fitness exercises would be, for example:

(40) FIG. 10A shows as a first fitness exercise F?.sub.1 pull-ups, where the lower limbs can be bent, for tall people all the time;
