UNIVERSAL FITNESS DEVICE

Description

[0001] The present invention relates to a fitness device that enables a variety of individual and whole-body fitness exercises, primarily for home use but also in fitness centers.

[0002] The fitness equipment manufacturing industry is increasingly showing a trend toward specialization, with ever more specific fitness machines designed and built for only a few, or even a single, exercise. This might impress a fitness center customer if the center boasts a wide variety of different, highly specialized machines and offers, or even professionally designs, a fitness program that involves a veritable circuit from one machine to the next, more or less through the entire inventory of the fitness center.

[0003] From an overall or economic perspective, however, such a specialization trend can run counter to the principles of sustainability. Fitness equipment is becoming increasingly specialized and is generally a massive and heavy iron construction, which is expensive and therefore, on the one hand, increasingly less suitable for home use, and on the other hand, also less compatible with the growing trend towards a more ecological and sustainable lifestyle, where fitness exercises rely more on body weight and less on auxiliary or assistive fitness equipment.

[0004] From a hygiene perspective – especially during pandemics and closed fitness centers – it is disadvantageous to have specialized fitness equipment unsuitable for home use, which is typically used by several customers in succession in fitness centers, again usually without cleaning or even disinfection being mandatory during breaks between users.

[0005] As mentioned previously, more complex fitness equipment is usually heavy iron constructions whose mechanics also require maintenance. Again, from a sustainability perspective, it would be desirable for fitness equipment to be made of materials that are more sustainable than iron or plastic.

[0006] Simpler fitness equipment, which would be suitable for home use, is usually smaller and takes up less space, but is then only suitable for one or a few exercises. Training with it can quickly become monotonous and simply boring.

[0007] International publication WO 2018 / 011650 A1, dated January 18, 2018, describes a foldable, freestanding exercise apparatus with a telescopically adjustable frame secured with pins or, more accurately, screws. This solution does not appear very stable. Furthermore, the pins permanently prevent the connecting bar or pull-up bar from rotating. Operating the exercise apparatus with the connecting bar or pull-up bar rotating is not intended. Additionally, the apparatus can only be folded by completely removing two locking brackets connecting the front and rear legs, and this does not achieve a zero-degree angle between the front and rear legs, or in other words, the legs are not congruent.

[0008] The solution to the problem initially consists in the design and construction of a universal fitness device that essentially comprises at least two front legs and at least two rear legs, each connected to the other at an upper end region by connecting joints and to at least one connecting bar or pull-up bar. Furthermore, a minimum embodiment of the universal fitness device according to the invention comprises at least two fixing brackets, each connecting a front and a rear leg, thus resulting in a fixed operating position of the universal fitness device at at least one predetermined spread angle between the front and rear legs.

[0009] Furthermore, according to an improved and preferred embodiment of the fitness device according to the invention, a reinforcement board can comprise a connecting board that fixes the at least two rear legs and reinforces the structure, preferably arranged in a lower end region of these rear legs. This reinforcement board can also serve as a step board and can be simply a flat board, but can also have a top surface that is approximately horizontal and can optionally be wide enough to accommodate a foot length and allow a user to stand comfortably on it.

[0010] Furthermore, a connection reinforcing the overall structure can optionally and generally also be provided on the front legs, for example in the form of a board, a strip, or a bracket. In a preferred embodiment, however, a series of bores or receptacles are arranged parallel to each other on the at least two front legs. Additional rods can be inserted into any two of these bores or receptacles, preferably at the same height, according to the invention. These rods can be solid or hollow and made, for example, of metal or wood. They can also have a round cross-section, but also a triangular, square, or hexagonal one. With appropriately shaped receptacles, a rotating or a non-rotating additional rod can be inserted as desired.

[0011] The mere fact that one or more additional rods are loosely inserted into the parallel holes or receptacles already provides additional stabilization to the reinforcement board; it can also be optional to fix the additional rod axially to the front legs, for example by means of set collars, nuts or star rings or even just with spring collars, e.g. called grippers, which are usually used to axially fix the weights of a barbell on the barbell bar.

[0012] Furthermore, it is planned to arrange the connecting or pull-up bar located in the upper end area in the same way as described for the additional bar, so that it is axially fixed on the one hand, but on the other hand can rotate around its longitudinal axis as required or not.

[0013] In a universal fitness device according to the invention, the first front leg is connected to the first rear leg and to the connecting bar or pull-up bar in a first connecting joint, and the second front leg is connected to the second rear leg and to the connecting bar or pull-up bar in a second connecting joint. These two connecting joints thus form a double joint. For this purpose, fitting bores are provided in the upper end region of the front and rear legs, through which the connecting bar or pull-up bar is guided, and adjusting rings are provided which can be fixed with set screws.

[0014] A preferred embodiment of a universal fitness device according to the invention further provides a locking mechanism. This includes, for example, at least one radial bore in the connecting or pull-up bar, as well as correspondingly arranged bores in the surrounding material of the upper end region of at least one front or rear leg. A cotter pin, bolt, or locking pin can be inserted into all these bores, the latter preferably with a knob at one end for easier handling and to prevent it from falling through the bores.

[0015] Furthermore, the same types of locking devices described above can also be used for the extension bars. For this purpose, the extension bars are also provided with the described radial bores, as are corresponding radial bores in the surrounding material around the bores or receptacles arranged parallel to each other in the front legs. Depending on where the extension bar is inserted, the locking pin can then be inserted through the radial bores and removed again. In any case, the described locking devices ensure that the connecting bar / pull-up bar and the extension bars can be operated as desired, rotating around their longitudinal axis or locked against rotation.

[0016] A further preferred embodiment of a universal fitness device according to the invention provides in the front legs not only the parallel bores or receptacles for the optionally positioned additional bars, but also, preferably, brackets or recesses in the material of the front legs that are repeated in the same sequence and also arranged in parallel. A barbell, for example, can be hung or placed in these brackets – each pair at the same height – at more or less any desired height.

[0017] As already mentioned, a universal fitness device according to the invention, even in its minimal version, comprises at least two fixing brackets, each connecting the front legs to the rear legs, preferably arranged in their lower end region. The length of these fixing brackets and their attachment determine a specific spread angle between the front and rear legs, as well as a specific, predetermined operating position of the universal fitness device. According to a further embodiment of a universal fitness device according to the invention, it is also possible to provide different spread angles and different operating positions. For this purpose, the fixing brackets are arranged at one end of each bracket on one of the front or rear legs by means of a pivot joint.The respective opposite ends of the fixing brackets can optionally be fastened at different heights, for example and preferably by means of a hand screw in threaded bushings that are embedded or inserted into the material of the leg.

[0018] Regarding the material of the legs and the entire universal fitness device, sustainable materials with a better environmental footprint are preferred. This can be, for example, and preferably, wood, ideally plywood, and furthermore preferably pressure-treated. Treatment or impregnation of the wood with zinc or copper sulfate, nanosilver, or other antibacterial, germicidal, and antiviral substances and solutions is also considered. Additionally, varnishes and other coatings that are particularly easy to clean or disinfect, or so-called lotus-petal varnishes, to which virtually nothing adheres, are suitable.

[0019] A universal fitness device according to the invention can be folded from its operating position into a space-saving folding or transport and storage position. For this purpose, the fixing brackets are rotatably arranged with the described swivel joints and can be loosened with the also described hand screws. With the hand screw loosened, the fixing brackets can be pivoted out of their respective mounting positions in the swivel joint to such an extent that they can be attached in a standby or waiting position not to the opposite leg, but to the same leg to which they are attached by means of the swivel joint. This is preferably done in a threaded bushing and preferably approximately in line with the longitudinal extent of the leg.Once both locking bars are released and secured, one or more safety pins that may have been inserted at the connecting joints can be removed, and the front and rear legs can be folded together. In other words, if, for example, a universal fitness device is resting flat on its rear legs on the floor, the angle of the front legs, which then protrude diagonally upwards, can be reduced to zero by also bringing them flat on the floor.

[0020] To facilitate this "exercise", if you will, rollers can optionally and furthermore be arranged on the backs of the rear thighs, for example in their lower end area below the reinforcement board or step board, over which the universal fitness device can be tilted and rolled away.

[0021] Feet, preferably replaceable, can also be provided at the lower end of both the rear and front legs. Felt glides are suitable, as are rubber feet or caps that can cover the entire lower profile of the leg.

[0022] As already mentioned, the reinforcement board located on the rear thighs, approximately in the lower end region, serves to reinforce the structure and also functions as a step board. A further function according to the invention is its use for rowing training. For this purpose, it can be equipped with attachments or at least a hole through which, for example, a rubber band or a so-called TheraBand can be threaded.

[0023] During both step aerobics and rowing, the universal fitness device would be subjected to lateral forces that could cause it to slide back and forth. To prevent this, the invention further provides for flattened sections on the lower end of the front legs of the front frame, allowing the front legs, or the universal fitness device as a whole, to be supported against a wall. Furthermore, the flattened section can have a recess that accommodates a wall baseboard, ensuring that the flattened section rests directly against the wall and not against the baseboard. Additionally, a wall mounting bracket, for example in the form of a hook-shaped profile, can be provided as an accessory, into which the universal fitness device can be hung using a positive-locking counterpart profile.

[0024] Regarding further accessories, a particularly complete universal fitness device according to the invention can include form-fitting mounts or rails for holding a bench, especially for bench presses. Furthermore, form-fitting mounts or rails for a small bench, or rather a seat board, can be arranged on rollers, thus limiting rowing training to the torso and arms, and also incorporating the legs.

[0025] According to a further embodiment, a universal fitness device according to the invention can have a connecting bar or pull-up bar which, although rotatably mounted in the at least two connecting joints as described, is mounted not only by means of the described locating bores, but also with low-friction mechanical rotary bearings such as ball or roller bearings. In this way, a good swinging motion or fitness exercises with swinging movements can also be achieved. Nevertheless, even in this case, a mechanical anti-rotation device can be provided to lock the rotation, as described with a cotter pin or locking pin, but also with a mechanical ratchet that can be locked and unlocked and can also provide detent positions corresponding to the operating positions defined by the length and mounting positions of the fixing brackets.

[0026] The connecting bar or pulley bar can also include one or more pulleys for various fitness exercises with weights on a cable system.

[0027] Ultimately, to enable space-saving storage of the universal fitness device according to the invention, despite its advantageously considerable size, a final embodiment features not only the described recesses or holders for the barbell in the front legs, but also slightly larger recesses at the same height in the rear legs. This allows a barbell to remain in the universal fitness device even in its folded or transport position. A separate, space-consuming storage location for the barbell is therefore unnecessary.

[0028] The present application discloses a first method for the application of a universal fitness device as disclosed, with two front legs and two rear legs connected to each other in two connecting joints and with a connecting or pull-up bar rotatably mounted in fitting bores between adjusting rings, as well as with two fixing brackets, in the execution of the following basic method steps: a) - Lifting and rolling the universal fitness device from its storage location to its setup location; b) - Releasing the locking brackets from their waiting or standby positions; c) - Folding the first front leg from the folded or transport position into the operating position; d) - Securing the first front leg using the first locking bracket; e) - Folding the second front leg from the folded or transport position into the operating position; f) - Securing the second front leg using the second locking bracket; g) - Lifting and setting up the universal fitness device; h) - Attaching or...Placing a barbell in two of the parallel holders in the front arms; i) - Inserting one or more additional bars into any two of the parallel holders in the front arms; j) - If desired, securing the additional bar(s) against rotation; k) - If desired, securing the connecting bar or pull-up bar against rotation; l) - Performing at least one of the fitness exercises; m) - Ending the fitness training; n) - Removing the barbell from its holders; o) - If necessary and desired, unlocking the connecting bar or pull-up bar.Horizontal bar; p) - if necessary and desired, unlocking the auxiliary bar(s); q) - if desired, removing the auxiliary bar from its auxiliary bar(s); q) - if desired, removing the auxiliary bar from its receptacles in the front legs; r) - releasing the first locking bracket from the first front leg; s) - locking the first locking bracket in the waiting or standby position; t) - releasing the second locking bracket from the second front leg; u) - locking the second locking bracket in the waiting or standby position; v) - grasping the connecting bar or horizontal bar and tilting it (whereby the front legs automatically fold into the folding or standby position).(Fold into transport position) using the rollers on the rear legs of the universal fitness device from its upright operating position to a position lying on its rear legs; w) - Lifting and rolling the universal fitness device from its installation location to its storage location.

[0029] A universal fitness device according to the invention offers the following advantages: It is very well suited for home use, but can also be used effectively in fitness centers. Many fitness exercises are possible with it. It is not limited to a few specific exercises. It is sustainable due to its lack of specialization, as well as the choice of materials, its weight, and its overall quality. It is easy to clean and disinfect, thus easily meeting increased hygiene requirements. It has no small, maintenance-intensive mechanisms. It is not excessively large, yet very complete. Training with it can be highly varied, preventing users from becoming bored quickly. It is stable and durable. The connecting bar / pull-up bar and the additional bar can be rotated or locked in place as desired. A barbell can be securely stored at virtually any height. The surfaces of this universal fitness device according to the invention are impregnated and / or surface-treated.A universal fitness device according to the invention provides an operating position and a space-saving folding or transport position. If provided, it can be stably supported and attached to a wall. If provided, it can also function well as a swing. A barbell can remain in the holders in the universal fitness device in the space-saving folding or storage position.

[0030] The disclosed different embodiments of a universal fitness device according to the invention can be combined with one another. For example, the embodiments with or without a reinforcement or step board can be combined at will and reciprocally with the different embodiments of a universal fitness device according to the invention with or without an additional bar or the described safety devices and brackets, and all of this in turn with the different embodiments of a further universal fitness device according to the invention with or without the described pivotability of the fixing brackets. The same applies, at will and reciprocally, to the different embodiments with or without the ability to fold from the operating position into a folding or...The transport position can be folded, as well as the design variants with or without wheels or those with or without the described wall mounting.

[0031] Further or advantageous embodiments of a universal fitness device according to the invention are the subject matter of the dependent claims.

[0035] The Fig. 1 Figure 1 shows a symbolic, exemplary, and perspective overall view of a first embodiment of a universal fitness device 100 according to the invention. A front leg pair vSp is formed from a left front leg 1a and a right front leg 1b, and a rear leg pair hSp from a left rear leg 2a and a right rear leg 2b. The front leg pair vSp and the rear leg pair hSp are connected by means of a double joint 200, whereby a connecting bar or pull-up bar 4 passes through only indicated fitting bores 27a and 27b in an upper end region oEb of the legs 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 legs 2a and 1a as well as 1b and 2b are connected by means of the connecting bar or pull-up bar 4.The horizontal bar is held together by 4 arranged adjusting rings 5a-5d, with only adjusting rings 5a and 5c visible in this perspective view.

[0036] In the front pair of legs 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 in the holders or recesses 6e and 6f. The barbell 300 also has weights or pairs of weights 25a and 25b, each of which is fixed with a star ring 26.

[0037] Also at regular intervals, but offset from the supports or recesses 6a-6l, bores or receptacles 7a-7n are arranged in the front legs 1a and 1b, forming the front leg pair vSp. Additional rods 8 of any height can be inserted into these bores or receptacles 7a-7n, as shown by way of example in bores or receptacles 7i and 7j.

[0038] Similar to a trestle or stepladder, the front leg 1a and the rear leg 2a, as well as the front leg 1b and the rear leg 2b, are each stabilized or fixed against further spreading by a fixing bracket 9a and 9b. A predefined length of the fixing brackets 9a and 9b, and their fixed arrangement as shown, preferably in a lower end region uEb in a respective mounting position Mp, results in a predetermined operating position Bp of the universal fitness device 100, with a similarly predetermined spreading angle Sw between the front legs 1a or 1b and the rear legs 2a or 2b.

[0039] Furthermore, this Fig. 1 It is still evident that a reinforcement board or step board 10 is arranged on the rear side of the rear legs 2a and 2b. As already mentioned, it can also be box-shaped and have a larger top surface 28, which can optionally be oriented approximately horizontally.

[0040] In the illustrated first embodiment of a universal fitness device 100 according to the invention, the two front legs 1a and 1b and the two rear legs 2a and 2b are arranged at the top of the connecting joints 3a and 3b such that the rear legs 2a and 2b are on the outside and the front legs 1a and 1b are on the inside. This arrangement can also be reversed or mixed; however, it is considered advantageous if the somewhat heavier rear legs 2a and 2b are arranged as far to the outside as possible, thus giving the universal fitness device 100 even more stability.

[0041] In the Fig. 2 is the first embodiment of a universal fitness device 100 according to the invention from the Fig. 1 Shown from a straight, rear view. All the elements shown are already known, except for the adjusting rings 5b and 5d, which are now also visible.

[0042] The Fig. 3 Figure 1 shows a second embodiment of a universal fitness device 100a according to the invention in a detailed view, which depicts only an upper end region oEb 1 of a first front leg 1c and a first rear leg 2c, as well as a second front leg 1d and a second rear leg 2d. The two first legs 1c and 2c are again arranged in a first connecting joint 3c by means of a connecting or pull-up bar 4a, and the two second legs 1d and 2d are arranged accordingly in a second connecting joint 3d. The two connecting joints 3c and 3d in turn form a double joint 200a, and the front legs 1c and 1d form a front leg pair vSp 1, and the rear legs 2c and 2d form a rear leg pair hSp 1. The front legs 1c and 1d each form a spreading angle Sw 1 with the rear legs 2c and 2d, and this in turn results in an operating position Bp 1 of the universal fitness device 100a.

[0043] Furthermore, it is evident that the first connecting joint 3c and the second connecting joint 3d are formed by fixing the legs 1c, 2c and 1d, 2d to the connecting bar 4a by means of set collars 5e-5h. Set collars 5e and 5g are only indicated by curved arrows, as they are hidden in this view. However, it is clearly visible that set collar 5h is itself fixed to the connecting bar 4a by means of a setscrew 11.

[0044] Furthermore, the construction of the connecting joint 3d is evident: the connecting or pull-up bar 4a is inserted into a fitting bore 27c in the front leg 1d and simultaneously into a fitting bore 27d in the rear leg 2d. In addition, this embodiment of a fitness device 100a according to the invention incorporates a locking mechanism 400. This is achieved by inserting a bolt or locking pin 13 with a knob 14 into a radial bore 12 in the connecting or pull-up bar 4a and into corresponding bores (not shown) arranged radially to the fitting bore 27c in the upper end region oEb 1 of the front leg 1d. The connecting or pull-up bar 4a is thus secured and can no longer rotate.

[0045] Furthermore, this Fig. 3 It is still recognizable how bores or receptacles 7o and 7p are arranged, for example, in the front legs 1c and 1d, for receiving additional rods 8, as in the previous Figuren 1 and 2 were shown.

[0046] In the Fig. 4 A fourth embodiment of a fitness device 100b according to the invention is shown symbolically and in a detailed drawing. This embodiment is characterized, on the one hand, by a locking device 400a, which this time is provided to secure against radial rotation in a rotation R 1, but also against axial displacement of an additional rod 8a, which in turn is inserted, for example, in a bore or receptacle 7q in a front leg 1e. The additional rod 8a has a radial bore 12a through which, but also through corresponding bores in the material of the front leg 1e (not shown in detail), a bolt or locking pin 13a with a knob 14a is inserted.

[0047] Otherwise, the front leg 1e, as previously described, has brackets 6m-6p and further bores or receptacles 7r-7t for receiving the additional bar 8a in a different position or for receiving further additional bars. The hatching S symbolically represents that a preferred material for manufacturing the front leg 1e and indeed the entire universal fitness device 100b is wood, preferably laminated wood, and even more preferably pressure-treated wood.

[0048] Furthermore, the front leg 1e also has a threaded bushing 17, so that a fixing bracket 9c, rotatably arranged in a pivot joint 15, preferably in a lower end region uEb 1, can be pivoted upwards so that a handscrew 16 can be screwed into the threaded bushing 17. In this way, the fixing bracket 9c can be pivoted from a mounting position Mp 1, in which it limits a spread angle Sw 2 and an operating position Bp 2 of the universal fitness device 100b, into a standby or waiting position Wp, in which the universal fitness device 100b is completely folded. This will be further described in the Fig. 9 be shown.

[0049] The Fig. 5 A fourth embodiment of a further universal fitness device 100c according to the invention is shown in a merely symbolic detail drawing, which is characterized by the fact that a rubber cap 18 is arranged by way of example in a lower end region uEb 2 of a front leg 1f.

[0050] Otherwise, familiar features are shown, such as a holder or recess 6q, a bore or receptacle 7u, and a fixing bracket 9d, which, as in the previous embodiment, is made from the Fig. 4 is pivotably arranged in a rotary joint 15a. The position or orientation of the fixing bracket 9d shown corresponds to a mounting position Mp 2, which in turn defines a spreading angle Sw 3 and an operating position Bp 3 of the universal fitness device 100c.

[0051] In the Fig. 6 A fifth embodiment of a fitness device 100d according to the invention is shown symbolically and schematically in a detailed drawing. This embodiment is characterized by a variable fixing option for the spread of the legs. For this purpose, a first threaded bushing 17a, indicated only by an arrow, is arranged on a rear leg 2e. A handscrew 16a is screwed into this bushing, thus fixing a fixing bracket 9e in its widest spread. Above the merely indicated threaded bushing 17a, further threaded bushings 17b and 17c are also arranged, which result in narrower spreads. The shown mounting of the fixing bracket 9e in a lower end region uEb 3 in a mounting position Mp 3 in the threaded bushing 17a results in a spread angle Sw 4 and an operating position Bp 4 of the universal fitness device 100d.Mounting the fixing bracket 9e in the threaded bushing 17b or 17c would each result in slightly altered spreading angles Sw 4 and slightly altered operating positions Bp 4 of the universal fitness device 100d.

[0052] The Fig. 7 Figure 1 shows, again in a purely symbolic and exemplary detail view from the rear, a sixth embodiment of a universal fitness device 100e according to the invention. Two rear legs 2f and 2g form a rear leg pair hSp 2, which is fixed by fixing brackets 9f and 9g in a respective mounting position Mp 4 to a front leg pair vSp 2, which in turn is formed from front legs 1g and 1h. All this results in an operating position Bp 5 of the universal fitness device 100e with spread angles Sw 5 between the rear leg 2f and the front leg 1g, as well as between the rear leg 2g and the front leg 1h. A reinforcement board or step board 10b connects the two rear legs 2f and 2g in a lower end area uEb 4 and optionally has a hole 19 arranged approximately in the middle, for example to be able to pass through or tie on a rubber or so-called Thera-Band.A top surface 28a of the reinforcement board or step board 10b can again be shaped approximately horizontally and wider.

[0053] Optionally, but useful for example for rowing or pulling exercises with the Thera-Band or 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 on the front faces of the front - in this view rear - thighs 1g and 1h.

[0054] Also in the lower end area uEb 4 of the rear, now front, legs 2f and 2g, rollers 20a and 20b are optionally arranged. These serve the purpose of enabling the universal fitness device 100e to be tilted and rolled away.

[0055] In the Fig. 8 A seventh embodiment of a further universal fitness device 100f according to the invention is shown, again only in an exemplary detailed drawing, which is characterized in that felt glides 22a and 22b are arranged in a lower end region uEb 5 of a rear leg 2h.

[0056] Otherwise, a roller 20c is now clearly visible, and indeed "in operation," because the universal fitness device 100f has been tilted onto its rear legs 2h and is essentially resting on them. The diameter of the roller 20c preferably exceeds the final dimension of a reinforcement board or step board 10c. It must be imagined that, in the horizontal position of the universal fitness device 100f indicated here, the front legs still extend upwards at a spread angle Sw 6, because a fixing bracket 9h is still screwed in a mounting position Mp 5 with a hand screw 16b and has not yet pivoted into the waiting position on the opposite front leg. In other words, the universal fitness device 100f is indeed in a horizontal position, but still in an operating position Bp 6.

[0057] The Fig. 9 Figure 1 shows an eighth and final embodiment of a fitness device 100g according to the invention, which is shown folded and lying down in a top view in a folded position Kp. Thus, not only the front legs 1i and 1j, but also the rear legs 2i and 2j are in the same plane, as are the fixing brackets 9i and 9j, which are now in their respective waiting positions Wp 1 and Wp 2. The spreading angle Sw 7 between the rear legs 2i and 2j and the front legs 1i and 1j is zero.

[0058] In a lower end section uEb 6, flattened sections 21c and 21d are now visible on the front faces of the front and inner legs 1i and 1j. Also present, and indicated only by curved arrows, are rollers 20d and 20e on the rear legs 2i and 2j. An additional bar 8b is inserted in the only indicated receptacles 7v and 7w. Otherwise, the universal fitness device 100g exhibits the previously known features, and these are therefore simply numbered consecutively without further description. Fig. 9 depicted.

[0059] A further difference according to the invention and optional compared to all previous embodiments of a universal fitness device 100, 100a-100f according to the invention from the previous Figuren 1-8 The difference lies in the fact that in the rear arms 2i and 2j, at the level of brackets 6r-6ü, recesses 23a-23l are also arranged in the front arms 1i and 1j. These recesses 23a-23l make it possible to leave a barbell 300a "stored" in the universal fitness device 100g even when it is folded in the folded position Kp, for example, in the brackets 6t and 6u where it is currently located.
