Description

[0001] The present invention concerns a multi-purpose machine for body building that is improved to solve some technical problems of the prior art, where, as is known, body building is that type of physical activity performed with certain tools, aimed at improving posture and at the same time shaping the body of a person, mainly by developing his / her overall muscle tone.

[0002] In the current state of the art, a series of machines, instruments and devices are known, which are made available to athletes and sportsmen in gyms to practice a series of very specific exercises. Generally, each machine is associated with a specific exercise, with a predetermined number of movements that can be performed by a person with his / her own body.

[0003] A first evolution of technology led to the creation of multi-purpose machines that allow persons to perform a multiple number of different types of exercises.

[0004] But in their first version, these machines had very bulky structures, and their functions were poorly integrated. Rather than representing a single multi-purpose machine, many of them were just a set of classic machines grouped together in a single space, or installed on a single frame. They therefore presented problems of handling, ease of use and safety for the user, with an exercise station located inside tension cables, with significant weights that were attached to various unstable structures.

[0005] A second evolution of technology has led to the creation of more advanced multi-purpose machines for body building, such as the one described in the Italian patent for industrial invention IT 102021000032381, issued on January 8, 2024.

[0006] The respective machines described in the above said patent are able to implement a significant number of exercises for the user, with a rapid transition from one exercise to another, and are perfectly integrated in their functions, without additional components that could be useless or redundant.

[0007] Furthermore, these machines are suitable for a use at home, and they are therefore compact, economical, can be installed in correspondence with the wall of a standard apartment and are robust, stable and safe.

[0008] The same machines can be easily configured according to the choice of exercises, and they allow for various levels of load, with weights that can be added progressively, to increase the intensity and physical effort required in the exercises.

[0009] The same machines can be further assembled and disassembled quickly and easily, they are easy and convenient to transport, and even when they are packed in a transport configuration they take up limited space, so that they can be transported in the trunk of a common vehicle.

[0010] Compared to the prior art, the present invention represents a further improvement of the machines for body building, in particular when it is compared to those described in the above said patent IT 102021000032381.

[0011] The present invention introduces some technical modifications and additions that solve some technical problems of the prior art during the assembly / disassembly and transport phases, providing greater safety and being ease for the user during the execution phase of the body building exercises, with less complexity of the overall structure of the machines and, consequently, lower economic cost for their production, manufacturing and marketing.

[0012] Therefore, it is specific subject of the present invention a multi-purpose machine for body-building, installed in correspondence of a wall, said machine comprising: a rigid supporting structure, consisting of two pairs of vertical bars that rest on the ground on their respective feet, and a pair of horizontal bars attached laterally to the same vertical bars, respectively in their upper part and in their lower part; a series of supports are hooked to the rear part of the above said vertical bars, and are stably fixed to the wall using wall plugs; a pair of movable arms, each of them interposed in correspondence with one of the respective pairs of vertical bars, fixed and hinged at the top with respective pivots, with respect to which the same movable bars are free to rotate in a clockwise or anti-clockwise direction with respect to a horizontal axis passing through the pivots and parallel to the wall; said machine being characterized in that further comprising: at least two pairs of perforated half-rings, each of which is incorporated into the respective right and left lateral profile of each of the above said vertical elements; said half-rings being placed in the upper part immediately forward and under the respective pivots; inside the holes of said perforated half-rings, are installed transversely and stably some respective end-of-run brackets and some additional optional safety brackets, all the brackets being represented by respective horizontal rigid bars, in such a way that the above said end-of-run brackets define a rigid support which keeps the above said movable arms having their free end at a fixed and predetermined height from the ground; or in such a way that the above said end-of-run brackets define a limit angle with respect to which the above said movable arms can rotate, until they reach with their free end a fixed and predefined maximum height or a fixed and predefined minimum height from the ground.

[0014] It is underlined that only few of the many conceivable embodiments of the present invention are here described, which are just some specific non-limiting examples, having the possibility to describe many other embodiments based on the disclosed technical solutions of the present invention. The same elements will be indicated by the same reference numbers in the various figures.

[0015] Figures 1 and 2 illustrate a multi-purpose machine for body building 100, according to the prior art of patent IT 102021000032381, installed in correspondence with a wall 118 and in a compact non-use configuration, with the arms 101 and 102 lowered and all the components grouped together in such a way as to occupy the least possible space.

[0016] The same machine 100 mainly comprises: a rigid support structure; a series of elements 116a, 116b, 116c, 116d which fix this structure stably to the wall 118; a pair of movable arms, 101 and 102, free to rotate in a clockwise or anti-clockwise direction with respect to a horizontal axis passing through pivots 114, 115 located at the top of the structure; at least two pairs of perforated half-rings, 103a, 103b, 103c, 103d (Figure 3), with respective end-of-run brackets 117a, 117c (Figures 4 and 6), so as to maintain the above said movable arms 101, 102 with the free end at a fixed and pre-established height from the ground.

[0017] More specifically, the rigid support structure is made up of two pairs of vertical bars that rest on the ground on respective feet 106, 107, and a pair of horizontal bars 112, 113 attached to them laterally, respectively in the upper part and in the lower part.

[0018] The series of elements 116a, 116b, 116c, 116d, consists of supports that are hooked to the rear part of the above said vertical bars, and are fixed permanently to the wall 118 using wall plugs.

[0019] The pair of movable arms consists of respective movable bars 101, 102, each of which is interposed in correspondence with one of the respective pairs of vertical bars, and fixed at the top with respective pivots 114, 115, with respect to which the same movable bars 101, 102 are free to rotate in a clockwise or anti-clockwise direction with respect to a horizontal axis passing through the pivots 114, 115 and parallel to the wall 118.

[0020] The two pairs of perforated half-rings, 103a, 103b, 103c, 103d, are each interposed between the respective movable bars 101, 102, and the respective pairs of vertical bars; the same half-rings are placed in the upper part immediately below the respective pivots 114, 115. Inside the holes of the perforated half-rings, 103a, 103b, 103c, 103d, end-of-run brackets 117a, 117c, and optional safety brackets 117b, 117d are permanently installed, all the brackets being represented by respective horizontal rigid bars.

[0021] In this way, the above said end-of-run brackets 117a, 117c define a rigid support that maintains the above said movable arms 101, 102 with the free end at a fixed and predetermined height from the ground. Or the same end-of-run brackets 117a, 117c define a limit angle with respect to which the above said movable arms 101, 102 can rotate, until they reach with the free end a maximum height or a fixed and predetermined minimum height from the ground.

[0022] In the same Figures 1 and 3, a pair of load bars 110, 111 is also illustrated, each of which is rigidly installed in correspondence with one of the respective movable bars 101, 102, and perpendicularly to it.

[0023] Then there are two series of weights, 108a, 108b, 108c, 108d, ...., and 109a, 109b, 109c, 109d, ...., said weights being made up of metal discs with holes in the center, which are installed and fixed stably in correspondence with the respective load bars 110, 111, by means of special locking clips. The weights can be installed in a free number chosen among those available.

[0024] In this way, the weights 108a, 108b, 108c, 108d, ...., and 109a, 109b, 109c, 109d, ...., constitute an additional load to the weight of the respective movable bars 101, 102. They oppose their lifting, and define body-building exercises characterized by different levels of difficulty and physical strength required for the user. The above said load bars 110, 111, also comprise a respective installation and removal mechanism, by screwing / unscrewing or by interlocking actions. In this way, they can be installed on the movable bars 101, 102, when an exercise requires the installation of weights, or they can be removed from the movable bars 101, 102, when it is necessary to reduce the overall space of the machine. This is the case, for example, of Figure 5, where the machine has the arms raised to the maximum height, positioned almost at 180 degrees and almost parallel to the wall.

[0025] In the respective Figures 3 and 5 it is also illustrated how the machine 100 further comprises a pair of handlebars 104, 105, each of which is rigidly installed at the front end of one of the respective movable bars 101, 102, and extending forward with respect to such end.

[0026] In a first configuration, the pair of handlebars 104, 105 is oriented outward with respect to the movable bars 101, 102, as illustrated in Figure 3.

[0027] In a second configuration, the pair of handlebars 104, 105 is oriented inward with respect to the movable bars 101, 102, as illustrated in Figure 5.

[0028] Each of the above said handlebars 104, 105 comprises a mechanism 120 for switching from the inward configuration to the outward configuration and vice versa.

[0029] With reference to Figures 8(a), 8(b) and 8(c), the mechanism 120 for switching from the inward configuration to the outward configuration and vice versa, comprises a perforated base element 121 connected to the handlebar 104. The perforated base element 121 is inserted inside the movable bar 101 at its respective front end, and it is fixed at a pre-established distance using locking stops 123a, 123b which intercept respective holes chosen from among the holes 122a, 122b, ..., 122n available inside the perforated base element 121.

[0030] The procedure for switching from the inward configuration to the outward configuration and vice versa involves: removing the locking stops 123a, 123b; extracting the handlebar 104 with the perforated base element 121 from the movable bar 101; rotating the handlebar 104 with the perforated base element 121 by 180 degrees with respect to its longitudinal axis; inserting the handlebar 104 with the perforated base element 121 into the movable bar 101; inserting the locking stops 123a, 123b.

[0031] Figure 7 illustrates an accessory 119 for connecting the handlebars 104, 105, applied to the second configuration in which the pair of handlebars 104, 105 is oriented inwards with respect to the above said movable bars 101, 102, as illustrated in Figure 5.

[0032] The accessory 119 consists of a bar that has seats at its respective ends, and an interlocking mechanism that intercepts and keeps the respective handlebars 104, 105 rigidly connected. In this way, both movable bars 101, 102 can be moved in a joint and simultaneous manner.

[0033] In Figures 9, 10, 11 and 12 the same machine 100 of the prior art of patent IT 102021000032381 is illustrated, in a configuration of actual use together with a bench 130, to perform lifting exercises while lying on a flat bench.

[0034] The machine 100 therefore further comprises a body-building bench 130 to be used simultaneously and in a coordinated manner to perform different types of exercises. For example, as illustrated in Figure 9, the bench 130 with the backrest lowered and placed in front of the machine 100 allows a user lying in a supine position to perform lifting exercises of the above said arms 101, 102 with the possible load of additional weights 108a, 109a.

[0035] Instead, as illustrated in Figure 10, the bench 130 with an inclined backrest and placed in front of the machine 100 allows a user sitting frontally to perform lifting exercises of the above said arms 101, 102, with the possible loading of additional weights 108a, 109a. And again, as illustrated in Figure 11, the bench 130 with an inclined backrest and placed in the opposite direction to the machine 100 allows a user sitting with his back turned to perform lifting exercises of the above said arms 101, 102, with the possible loading of additional weights 108a, 109a.

[0036] And again, as illustrated in Figure 12, the bench 130 with the backrest lowered and placed in front of the machine 100 allows a user to perform lifting exercises on one of the above said arms 101, 102 at a time, with the possible load of additional weights 108a, 109a.

[0037] In Figures 13, 14 and 15 the same machine 100 of the prior art of patent IT 102021000032381 is illustrated, in a configuration of actual use, to perform additional exercises. For example, as illustrated in Figure 13, the machine 100 includes a load of weights to perform lifting exercises while sitting on the ground and positioned in front of the machine itself. Instead, as illustrated in Figure 13, the machine 100 has the arms locked to perform exercises for lifting the body on one's arms and / or lifting one's legs. And again, as illustrated in Figure 15, the machine 100 includes a load of weights for doing lifting exercises while standing with the knees bent and placed in front of the machine itself.

[0038] According to an embodiment of the same machine as patent IT 102021000032381, the above said rigid support structure constitutes a frame made of metal, in which the lateral surfaces of the two pairs of vertical bars, of the horizontal bars 112, 113, of the feet 106, 107 and of the movable arms 101, 102, have a general thickness of 3 mm, with reinforcements of an additional 5 mm at the contact points, thus arriving at a total thickness of 8 mm at these points.

[0039] Furthermore, the machine 100 has dimensions of 95 cm in width, 100 cm in height, 45 cm in depth in the lower part, where the feet are located, and 15 cm in depth in the upper part on the wall. The machine 100 has a total weight, including accessories, of approximately 60 kg.

[0040] According to the same embodiment of the machine of patent IT 102021000032381, the above said rigid support structure, which constitutes the frame, can be connected to at least 4 counter-frames. The series of supports 116a, 116b, 116c, 116d consists of 4 respective supports having a thickness of 8 mm each, and the frame is fixed to the 4 counter-frames using 4 respective 12 mm screws. Layers of acrylonitrile butadiene styrene - ABS are interposed at the contact points.

[0041] Further according to the same embodiment of the machine of the patent IT 102021000032381, the above said movable arms 101, 102, as a consequence of the above said extension mechanism of the respective handlebars 104, 105 which are connected to the same movable arms 101, 102 via their base element perforated with the movable stops, constitute telescopic arms extendable, up to a maximum length of approximately 200 cm.

[0042] For the adjustment of the telescopic arms there are a series of bushings, of which 12 are made of steel and 12 are made of derlin.

[0043] The above said end-of-run brackets 117a, 117c and the above said optional safety brackets 117b, 117d are made up of respective horizontal rigid bars, made of steel, and having a respective length of 10 cm.

[0044] Figures 16, 17, 18 and 19 show an improved multi-purpose machine for body-building 200, according to the present invention, installed in correspondence with a wall 218.

[0045] The machine 200 comprises, as components already known from the prior art, a rigid support structure and a pair of movable arms 201 and 202.

[0046] The rigid support structure consists of a pair of vertical elements 219 and 220 that rest on the ground on respective feet 206 and 207, and a pair of horizontal bars 212 and 213, attached laterally to the same vertical elements 219 and 220, respectively in their upper part and in their lower part. A series of supports are attached to the rear part of the same vertical elements 219 and 220, which are fixed stably to the wall 218 using wall anchors. The pair of movable arms 201 and 202 are inserted in correspondence with one of the respective vertical elements 219 and 220, fixed and hinged at the top with respective pivots 214 and 215. The movable arms 201 and 202 are free to rotate clockwise or anti-clockwise with respect to a horizontal axis passing through the pivots 214 and 215, and parallel to the wall 218.

[0047] A first innovative feature of the improved machine 200 is that of further comprising at least two pairs of perforated half-rings, 203a and 203b, and 203c and 203d, as illustrated in Figure 19.

[0048] Each of the half-rings is incorporated into the respective right and left side profile of each of the above said vertical elements 219 and 220. The half-rings are located in the upper part immediately forward and under the respective pivots 214 and 215. With reference to Figures 19, 20, 21 and 22, inside the holes of the perforated half-rings, 203a and 203b, and 203c and 203d, respective end-of-run brackets 217a, 217c are installed transversely and stably, in addition to additional optional safety brackets (not shown in the figure), all the brackets being represented by respective horizontal rigid bars. In this way, the above said end-of-run brackets 217a and 217c define a rigid support that maintains the above said movable arms 201 and 202 with the free end at a fixed and pre-established height from the ground, or the above said end-of-run brackets 217a and 217c define a limit angle with respect to which the above said movable arms 201 and 202 can rotate, until they reach with the free end a maximum height or a fixed and pre-established minimum height from the ground.

[0049] A second innovative feature of the improved machine 200 is that it can include at least two additional pairs of perforated half-rings, having the same hole pattern and being laterally coaxial to the previous ones, each half-ring incorporated into a respective internal plate, 221a and 221b, and 221c and 221d (Figure 19), connected internally to the respective right and left lateral profile of each of the above said vertical elements 219 and 220. The above said additional half-rings are placed in the upper part immediately forward and below the respective pivots 214 and 215. Inside the holes of the above said perforated half-rings, 203a and 203b, and 203c and 203d, and of the above said additional perforated half-rings on the internal plate, 221a and 221b, and 221c and 221d, are installed transversely and stably the respective end-of-run brackets 217a and 217c, and the additional optional safety brackets (not shown in the figure), all the brackets being represented by respective horizontal rigid bars.

[0050] In this way, the overall structure of the improved machine 200 is particularly robust, and the end-of-run brackets 217a and 217c, with additional optional safety brackets, are able to support significant loads, taking into account both the weights installed on the machine 200 for body building activities, and the weight of the person who in some exercises may lift himself onto the above said arms 201 and 202 of the machine, and the force exerted by a possible impact due to the free fall of the same arms 201 and 202 on the end-of-run brackets 217a and 217c, and on the additional optional safety brackets.

[0051] A third innovative feature of the improved machine 200 is that the hole pattern of the above said perforated half-rings, 203a and 203b, and 203c and 203d, and of the above said additional perforated half-rings on the internal plate, 221a and 221b, and 221c and 221d, can approximately follow the design of a letter "J", more precisely the straight line tangent to the mathematical curve identified by the sequence of holes can be, in some critical points, perpendicular to the longitudinal direction of the respective movable arms 201 and 202.

[0052] In this way the end-of-run brackets 217a and 217c, with additional optional safety brackets, are able to support the loads exerted on their surface more efficiently.

[0053] A fourth innovative feature of the improved machine 200 is that the above said pivots 214 and 215, with respect to which the above said movable arms 201 and 202 are free to rotate clockwise or counterclockwise, may be constituted by respective ball bearings.

[0054] In this way, friction during the rotation of the arms 201 and 202 can be decreased, the maneuverability and comfort of use of the machine 200 can be increased during the execution of body building exercises by a person, a more precise overall balance of the weights can be maintained, wear of the materials can be decreased and therefore the efficiency and operating life of the machine 200 can be increased.

[0055] As in the already known applications of the prior art, the improved machine 200 of the present invention can further comprise: at least a pair of load bars 210 and 211, and at least two sets of weights.

[0056] Each load bar 210 and 211 is rigidly installed in correspondence with a respective mobile arm 201 and 202, and perpendicularly to it.

[0057] The two sets of weights comprise metal discs perforated in the center, each of which is installed and fixed stably in correspondence with the respective load bars 210 and 211 through special locking stops. The above said installed weights can be in a free number chosen among those available.

[0058] In this way the weights constitute an additional load to the weight of the above said respective mobile arms 201 and 202, they oppose their lifting, and they define body-building exercises characterized by different levels of difficulty and physical strength required for the user.

[0059] The same load bars 210 and 211, may comprise a respective installation and removal mechanism, by screwing / unscrewing or by interlocking actions, so that they may be installed on the movable arms 201 and 202, when an exercise involving the installation of weights is required, or they may be removed from the movable arms 201 and 202, when it is necessary to reduce the overall space of the machine, for example with the arms raised to the maximum height, positioned almost at 180 degrees and almost parallel to the wall.

[0060] As in the already known applications of the prior art, the improved machine 200 of the present invention may further comprise at least a pair of handlebars 204 and 205. Each of them may be rigidly installed at the front end of one of the respective movable arms 201 and 202, and extend forward with respect to such end. In a first configuration, the above said pair of handlebars 204 and 205 can be oriented outwards with respect to the above said movable arms 201 and 202. In a second configuration, the above said pair of handlebars 204 and 205 can be oriented inwards with respect to the above said movable arms 201 and 202. Each of the above said handlebars 204 and 205 can comprise a mechanism for switching from the inward configuration to the outward configuration and vice versa.

[0061] The above said mechanism comprises a perforated base element 222 connected to the handlebar 204. The perforated base element 222 can be inserted inside the movable arm 201 at its respective front end, and can be fixed at a predetermined distance using locking stops that intercept respective holes chosen from those present inside the perforated base element 222.

[0062] The process of switching from the inward configuration to the outward configuration and vice versa, involves: removing the locking stops; extracting the handlebar 204 with the perforated base element 222 from the movable arm 201; rotating the same handlebar 204 with the perforated base element 222 by 180 degrees with respect to its longitudinal axis; inserting the handlebar 204 with the perforated base element 222 into the movable arm 201; inserting the locking stops.

[0063] The above said movable arms 201 and 202, as a consequence of the above said extension mechanism of the respective handlebars 204 and 205, which are connected to the same movable arms 201 and 202 via their base element perforated with the movable stops, constitute telescopic arms that can be extended up to a pre-established maximum length.

[0064] As in the already known applications of the prior art, the improved machine 200 of the present invention may further comprise a body building bench to be used simultaneously and in coordination with the machine 200 to perform different types of exercises. For example: the bench with a lowered backrest and placed in front of the machine 200 allows a user lying in a supine position to perform lifting exercises of the above said arms 201 and 202 with the possible loading of additional weights. The bench with an inclined backrest and placed in front of the machine 200 allows a user sitting frontally to perform lifting exercises of the above said arms 201 and 202 with the possible loading of additional weights. The bench with an inclined backrest and placed in the opposite direction to the machine 200 allows a user sitting with his back turned to perform lifting exercises of the above said arms 201 and 202 with the possible loading of additional weights. The bench with the backrest lowered and placed in front of the machine 200 allows a user to perform lifting exercises of one of the above said arms 201 and 202 at a time, with the possible loading of additional weights.

[0065] The present invention therefore achieves all the expected objectives. It introduces to the machines for body building some technical modifications and additions that solve some technical problems of the prior art during the assembly / disassembly and transport phases, providing greater safety and ease for the user during the execution phase of the body building exercises, with less complexity of the overall structure of the machines and, consequently, lower economic cost for their production, manufacturing and marketing.

[0066] The present invention has been described by making reference to some non limiting examples and following some preferred embodiments; however it is clear that modifications and / or changes can be introduced by those skilled in the art without departing from the relevant scope, as defined in the enclosed claims.
