Description

[0001] The present invention is located in the technical field of gym and fitness machinery and tools; in particular, an exercise device for the training and/or rehabilitation of a generic user forms the object of the present invention.

[0002] The exercise devices that are currently on the market and dedicated to the physical strength training of the user are mainly divided into two types: those based upon weight lifting and those without weights.

[0003] To the first type belong those exercise devices consisting of a single machine or of combined machines that integrate a plurality of tools in order to allow for the execution of a multiplicity of exercises. Both the single machine and the combined machines have a high mass and are bulky, and they therefore require space not only for the positioning thereof, but also during use.

[0004] These machines, single or combined, are essentially mechanical and, since they are not equipped with systems for monitoring the performance of the exercise, they are configured as passive machines.

[0005] The second type comprises machines that do not make use of weight, but instead exploit a different technology in order to generate the load necessary for training. For example, air resistance, water resistance (as in the case of rowers) or magnetic resistance are used. This second type of machinery boasts reduced size and lower mass, but the number and variety of exercises that may be performed using one machine is nonetheless limited. Furthermore, machines of the second type have a higher cost than those of the first type and this difference is essentially due to the different technological complexity of the product.

[0006] Disadvantageously, although machines of the second type are equipped with control electronics, they are not capable of actively interacting with the user and are therefore also configured as passive machines.

[0007] Interactive exercise devices have recently been introduced for training, which include a screen and a pair of arms within which a rope slides to be connected to a plurality of tools to be grasped/gripped in order to perform exercises.

[0008] An example of these interactive exercise devices is described in EP3833454A1, wherein each arm is connected to a support frame by means of a multi-axis hinge. Disadvantageously, considering the stresses to which the arms are subjected during exercise, the multi-axis hinge is an element of weakness, easily prone to failure, which defines the maximum load that may be generated by the device.

[0009] A further example of an interactive exercise device is described in EP3691758A2, where each arm is connected to the support frame by mean of a slider sliding along a rail. Unfortunately, in EP3691758A2 the slider also represents an element of weakness, insofar as, proportionally, as the load increases, the probability increases of the slider breaking, which slider risks being torn from the rail due to the stresses exerted by the user during training.

[0010] The object of the present invention is to propose an exercise device capable of at least partially overcoming the drawbacks mentioned above.

[0011] In particular, the object of the present invention is to obtain an exercise device wherein each arm is connected to the support frame in a secure manner, without the connection constraint being configured as an element of weakness such as to limit the maximum load tolerable by the device.

[0012] A further object of the present invention is to combine the advantages of both the first and second types of exercise devices according to the prior art and to render the device interactive for the user.

[0013] A still further object of the present invention is to improve the connection of the tools to the exercise device in such a way that, by simplifying the attachment/detachment of tools, it is possible to expand the range of exercises available in making the device highly versatile.

[0014] These purposes are achieved with an exercise device for the training and/or rehabilitation of a user according to claim 1. The dependent claims describe preferred embodiments of the invention.

[0016] In the following description, elements common to the various embodiments represented in the drawings are indicated with the same reference numerals.

[0017] In said drawings, an exercise device according to the invention has been indicated in the entirety thereof with the numeral 1.

[0018] For the purposes of this discussion, the term "interactive" indicates the existence of reciprocal activity between the exercise device and a generic user. In other words, the exercise device may provide an output in response to an input received from the user and/or may give an input to the user who in turn will be able to respond to the exercise device in providing an output in response.

[0019] In a general embodiment, the exercise device 1 for the training and/or rehabilitation of a user comprises a support frame 2, an interactive screen 3, a pair of arms 4, a transmission system 5 and a control unit 7.

[0020] The support frame 2 is suitable for being installed on a wall W.

[0021] The interactive screen 3 is suitable for receiving instructions and providing information to the user, and said interactive screen is applied to the support frame 2 and is supported by the same.

[0022] The pair of arms 4 is movable by the user, in such a way as to be arranged for performing gymnastic and/or rehabilitative exercises.

[0023] The transmission system 5 is configured to generate a load and comprises a motor 50, a pair of drums 51, a first rope 6' and a second rope 6". The motor 50 generates a resisting force. As regards the pair of drums 51, around a first drum 51' of such a pair of drums 51 the first rope 6' is wound and around a second drum 51" of such a pair of drums 51 the second rope 6" is wound. The first rope 6' connects the transmission system 5 to a first arm 4' of the pair of arms 4 and the second rope 6" connects the transmission system to a second arm 4" of the pair of arms 4.

[0024] The control unit 7 is configured for managing the transmission system 5 and the interactive screen 3.

[0025] The first arm 4' and the second arm 4" are connected to the support frame 2 by means of a carriage group 40, respectively. Furthermore, the support frame 2 comprises a pair of uprights 20', 20" oriented along an axis V. Each carriage group 40 encloses with contact and wraps at least partially a respective upright 20'; 20" of said pair of uprights 20', 20" so as to be translatable along the axis V and rotatable about said axis V.

[0026] According to an embodiment shown in the attached Figure 8, the transmission system 5 also comprises a differential 52 for rendering the first drum 51 independent from the second drum 51".

[0027] Advantageously, notwithstanding the presence of the single motor 50, the independence of movement between the first and second drums allows for performance of exercise using simultaneously the first and second ropes or only one of the two ropes. The use of the single motor implies lower mass, lower current absorption, less heat being generated and less sophisticated control electronics with a consequent reduction in construction costs compared to machinery comprising two or more motors.

[0028] Preferably, the motor 50 generates a resisting force, functioning as a brake. Such a motor 50 is brushless, in such a way as to minimize wear.

[0029] Advantageously, the motor allows the resisting force exerted on the first and second ropes to be adjusted with extreme precision. In generating the resisting force, i.e. operating as a brake, the motor is without retraction control.

[0030] The user, pulling the first rope 6' and/or the second rope 6", generates a pulling force which opposes the force generated by the transmission system, thus allowing for exercising of the muscles involved. The transmission system 5 is housed in a space inside the exercise device 1, in particular at a lower end of the support frame 2.

[0031] In the present description, the terms "upper" and "lower" refer to the exercise device 1 in an operating condition (e.g. Figures 1-3).

[0032] According to the embodiment of Figure 8, the transmission system 5 also comprises a reducer 53 positioned between the motor 50 and the differential 52, in order to amplify the torque generated by the motor 50, reducing the rotational speed.

[0033] Advantageously, the exercise device which is the object of the present invention is compact in size since the presence of the reducer makes it possible for high loads to be set during exercise sessions whilst maintaining reduced motor dimensions. In addition, the small size of the motor ensures lower current absorption and a reduction in the heat generated and in the overall weight of the exercise device.

[0034] According to an embodiment shown in the attached Figures 9-9c, the carriage group 40 comprises a carriage body 41 and an adjustment handle 42 for setting the axial and angular position of the carriage group 40 about the axis V.

[0035] The carriage body 41 comprises a first portion 41' and a second portion 41" which are mirrored with respect to an imaginary plane of symmetry S passing through the axis V. Said first portion 41' and second portion 41" are fitted around the respective upright 20'; 20" so as to enclose it with contact and wrap it at least partially.

[0036] Furthermore, the first portion 41' and the second portion 41" are separated from each other by an axial slot 43 oriented parallel to the axis V and are connected together by a threaded screw 44 oriented along a direction orthogonal to that defined by the axis V.

[0037] The adjustment handle 42 engages the threaded screw 44 and is rotatable between a carriage movement position (Figure 9b), wherein the axial slot 43 is sufficiently wide to allow the axial and angular adjustment of the carriage group 40, and a carriage locking position (Figure 9c), wherein the width of the axial slot 43 is reduced by tightening the threaded screw 44 and the carriage group 40 is locked in a desired axial and angular position.

[0038] It should be noted that the adjustment of the axial position of the carriage group 40 is intended along the axis V, whilst the angular adjustment is intended around the axis V.

[0039] Preferably, the carriage body 41 is substantially coaxial to the upright 20'; 20".

[0040] Advantageously, the carriage group is extremely compact and makes it possible to adjust the first and second arms in the three-dimensional space, discharging the forces generated by the user during exercise onto the support frame. Given the magnitude of the forces produced during exercise by the user, the carriage group is of fundamental importance in terms of safety since it remains perfectly constrained to the support frame without the risk of being torn from the respective upright.

[0041] Furthermore, the carriage group allows for the performance of a multiplicity of exercises by virtue of the possibility of adjusting the position thereof both axially and angularly.

[0042] According to one embodiment and in accordance with the attached Figures 9-9c and 10-10b, the first arm 4' and the second arm 4" comprise a proximal end 4a provided with a fork group 8 engaged with the carriage group 40, respectively.

[0043] The first portion 41' and the second portion 41" are made in one piece so as to form a monolithic block, and are further provided with a respective crescent element 45 of semi-circumferential shape where a plurality of angularly spaced radial notches 46 have been obtained and are engageable by the fork group 8.

[0044] The plurality of radial notches 46 makes it possible to adjust the positioning of each arm (first arm 4' and/or second arm 4") according to a desired angle of inclination.

[0045] Preferably, in the monolithic block formed by the first portion 41' and the second portion 41" of the carriage body 41, a gasket seat 48 is obtained, where a sealing element is housed in order to improve the locking of the carriage body 41 onto the respective upright 20'; 20". In other words, when the threaded screw 44 is tightened by means of the adjustment handle 42, i.e. in the carriage locking position, the sealing element grips the upright 20'; 20" so as to improve the axial and radial locking of the carriage group 40.

[0046] According to one embodiment, the first arm 4' and the second arm 4" comprise a tubular element 80 within which the first rope 6' or the second rope 6" slides, respectively.

[0047] The fork group 8 is positioned at the proximal end 4a of each arm 4'; 4" and comprises an arm locking element 81 and an elastic element 82.

[0048] The arm locking element 81, for example a tie or a tab, is engageable with the plurality of radial notches 46 so as to lock the tubular element 80 according to the desired angular inclination.

[0049] Preferably, the arm locking element 81 is connected to the tubular element 80.

[0050] For example, the arm locking element 81 is arranged along a direction orthogonal to that defined by the axis V.

[0051] The elastic element 82 connects the tubular element 80 to the carriage group 40.

[0052] The first arm 4' and the second arm 4" are movable, respectively, between a fixed position (Figures 10a and 15), wherein the arm locking element 81 engages a radial notch of the plurality of radial notches 46, thus defining a precise angular inclination of each arm, and a movable position (Figures 10b and 15a), wherein, by moving the tubular element 80 away from the carriage group 40, and thus lengthening the elastic element 82, the disengagement of the arm locking element 81 from the radial notch is obtained and the arm is positionable according to a new desired angular inclination.

[0053] It is obvious that once the new angular position of the first arm 4' and/or of the second arm 4" has been decided, upon the release of the tubular element 80 the arm locking element 81 will engage with the radial notch associated with the new desired angular inclination.

[0054] According to the embodiment in accordance with the attached Figures 10-10b, the fork group 8 comprises a pair of plates 8', 8" facing each other, where in each plate of said pair of plates 8', 8" a slotted hole 84 is obtained, engaged by a pin 47 protruding from each crescent element 45.

[0055] The fork group 8 further comprises a mechanical safety stop 83 to prevent the accidental disengagement of the arm locking element 81 from the radial notch. This mechanical stop 83 comprises a lever 85, a second elastic element 86 and a fulcrum 87.

[0056] The lever 85 extends between a first end 85' engageable with the pin 47 and a second end 85" opposite to the first end 85' and operable by the user (Figures 15-15a). The lever 85 is rotatable about the fulcrum 87.

[0057] The second elastic element 86 connects the tubular element 80 to the second end 85".

[0058] The mechanical stop 83 is operable between a safety position (Figures 10a and 15) and a disengagement position (Figures 10b and 15a).

[0059] In the safety position, the first end 85' is engaged with the pin 47 and the arm locking element 81 engages a radial notch of the plurality of radial notches 46 so that the first 4' arm and/or the second 4" arm are in the fixed position.

[0060] In the disengagement position, the user, by approaching the second end 85" to the tubular element 80 and compressing the second elastic element 86, may move the tubular element 80 away from the carriage group 40 so as to disengage the arm locking element 81 from the radial notch and arrange the first arm 4' and/or the second arm 4" in the movable position.

[0061] Preferably and in accordance with the attached Figures 15 and 15a, the first end 85' is hook-shaped.

[0062] According to the embodiment shown in the attached Figures 11-11c, the first arm 4' and the second arm 4" comprise a distal end 4b provided with an accessory coupling system 9, respectively. Said accessory coupling system 9 is suitable for connecting the first rope 6' or second rope 6" to a generic tool grippable by the user for performing a gymnastic and/or rehabilitative exercise.

[0063] In accordance with the embodiment shown in the attached Figures 7 and 13, the transmission system 5 also comprises a plurality of return pulleys 54 for connecting the first rope 6' and the second rope 6" to the accessory coupling system 9 to which a plurality of different tools for performing exercises may be connected.

[0064] According to one embodiment, the accessory coupling system 9 comprises a box-shaped casing 90, an accessory coupling element 91, a locking pin 95 and a third elastic element 97.

[0065] The box-shaped casing 90 is connected to the first rope 6' or to the second rope 6", respectively.

[0066] The accessory coupling element 91 is suitable for being connected to the generic tool grippable by the user. Said accessory coupling element 91 further comprises a coupling portion 92 and a cylindrical portion 93 housed inside the box-shaped casing 90. The cylindrical portion 93 in turn comprises a small-diameter region 94, whilst the coupling portion 92 is couplable to the generic tool.

[0067] Preferably, the coupling portion 92 is conical or frusto-conical in shape.

[0068] The locking pin 95 comprises a head 95a and a stem 95b engageable with the cylindrical portion 93. The stem 95b further comprises a cylindrical region 96' and a lowered region 96". Preferably, the lowered region 96" has a concave profile facing the cylindrical portion 93.

[0069] The third elastic element 97 is housed within the box-shaped casing 90 and is interposed between a wall of the box-shaped casing and a terminal end of the stem 95b of the locking pin 95.

[0070] The third elastic element 97 at rest ensures the engagement of the cylindrical region 96' of the stem 95b with the small-diameter region 94, so as to keep the accessory coupling element 91 locked inside the box-shaped casing 90 (Figure 11a).

[0071] In contrast, when compressed by the user, the third elastic element 97 allows the lowered region 96" to be aligned with the small-diameter region 94, so as to make the accessory coupling element 91 removable from the box-shaped casing 90.

[0072] According to the embodiment of Figure 12, at the accessory coupling system 9 there is a pair of counter-rotating pulleys 98 between which the first rope 6' or the second rope 6" runs. Such a pair of counter-rotating pulleys 98 allows the connection of the first rope 6' or second rope 6" with the box-shaped casing 90, so as to allow the user to pull the first rope 6' or second rope 6" regardless of the position of the first arm 4' or of the second arm 4".

[0073] Preferably, the pair of counter-rotating pulleys 98 is covered by a protective shell 99 connecting the tubular element 80 to the accessory coupling system 9.

[0074] According to the embodiment shown in Figure 12a, the pair of counter-rotating pulleys 98 is supported by a fork 980 whereupon at least one rolling element 981 with a low friction coefficient, such as a bearing or bushing, is keyed. A bushing 982, insertable into the tubular element 80, is mounted on the at least one rolling element 981.

[0075] According to one embodiment, the support frame 2 comprises a pair of doors 21 covering the pair of arms 4. The pair of doors 21 is closed to cover the pair of arms 4 when the exercise device is in the arm reclosing configuration (Figure 4).

[0076] In contrast, when the exercise device 1 is in the arm opening configuration (Figures 1-3) for exercising and/or rehabilitation, the pair of doors 21 is opened, so as to allow the user to move the pair of arms 4.

[0077] Preferably, the exercise device 1 may be used for performing free-body exercises even when it is in the arm reclosing configuration. In other words, the user does not require the pair of arms 4 in order to perform free-body exercises.

[0078] According to an embodiment shown in Figures 7 and 14, the exercise device also comprises a vision system 22 engaged with and fixed to the support frame 2. Such a vision system 22 comprises a pair of video cameras arranged so as to entirely frame the user while using the exercise device 1.

[0079] Advantageously, the installation of the pair of cameras allows for optimal framing of the user during the execution of physical exercises.

[0080] According to an embodiment shown in Figure 14, the exercise device 1 also comprises a microphone 23 for receiving as input vocal instructions from the user.

[0081] According to an embodiment shown in Figure 14, the exercise device 1 also comprises an audio system 24 which in turn comprises at least one audio speaker to output instructions and/or information and/or music to the user.

[0082] According to an embodiment shown in Figure 14, the exercise device 1 also comprises an air perfuming and/or sanitizing system 25, so as to perfume and/or sanitize the air surrounding the exercise device 1.

[0083] According to an embodiment shown in Figure 16, the exercise device 1 also comprises a lighting system 26. The light intensity and/or the color temperature of said lighting system 26 is adjustable by means of the control unit 7.

[0084] According to an embodiment not shown in any figure, the exercise device 1 may also be used for "suspension" exercises. In particular, at least one further fixed rope, possibly provided with a harness and/or handle, may be applied to the first arm 4' and/or the second arm 4" and the user, by hanging onto the fixed rope, may at least partially exploit his/her body weight in order to perform exercises at least partially suspended. By means of the adjustable angular inclination of the arms, it is possible to obtain different inclinations of the fixed rope and therefore a plurality of suspended exercises are possible.

[0085] Alternatively, the at least one further fixed rope may be directly attached to the accessory coupling system 9 where a stop element is present that locks the first rope 6' and/or the second rope 6". Or alternatively, instead of the stop element, it is the motor 50 itself that locks the first rope 6' and/or the second rope 6" in such a way that the at least one further fixed rope engaged with the accessory coupling system 9 does not slide when the user is performing suspended exercises.

[0086] Innovatively, the exercise device of the present invention fully fulfills the intended object thereof. In particular, the carriage group constrains the pair of arms to the support frame in a safe and effective way, since it allows the forces exerted by the user during physical and/or rehabilitation training to be discharged onto the support frame.

[0087] Advantageously, when the carriage group is in the carriage movement position, the axial and angular adjustment of the carriage body is facilitated, since the first (or second) rope connecting the transmission system to the accessory coupling system opposes the force of gravity and slows the descent of the carriage group along the respective upright.

[0088] According to an advantageous aspect, the accessory coupling system is practical and functional, since it allows for rapid coupling/uncoupling of tools to the exercise device.

[0089] According to a still further advantageous aspect, the transmission system differs from the prior art in that it generates the load by functioning as a brake without being feedback controlled.

[0090] According to a still further advantageous aspect, the exercise device which is the object of the present invention may also be used for "suspension" training.

[0091] To the embodiments of the exercise device according to the invention, a person skilled in the art, in order to meet contingent needs, may make modifications, adaptations and replacements of elements with functionally equivalent ones, without leaving the scope of protection of the following claims. Each of the features described as belonging to a possible embodiment may be obtained independently of the other described embodiments.
