Description

Field of the invention

[0001] The present invention relates to a training apparatus comprising a frame which defines a training area, wherein active surface elements are configured for supporting feet of the user in the training area, and wherein the surface elements can endlessly revolve in a loop.

[0002] In general, the present invention relates to exercising or physical training apparatuses, specially adapted for conditioning the cardio-vascular system, for training agility or co-ordination of movements, and for recreative purposes, in particular for indoor use.

[0003] The present invention finds preferred application in the fitness, training, and gym activity fields.Background art

[0004] The ever-increasing number of users who frequent gyms, fitness centers or physical training studios makes it difficult to train fluidly, especially at peak times where the training equipment needs to be shared among a large number of users.

[0005] This unfavorable situation often creates friction between users who have limited time to train.

[0006] There exist several types of training apparatuses, which simulate walking / running and climbing of stairs.

[0007] Document US2016367859A1 relates to a sporting apparatus comprising an endless belt disposed on a structure body, wherein the endless belt has a tilt angle for providing a gradually increased or decreased slope, so that it can rotate relative to the structure body and provide a simulated running situation in a planar road or a mountain.

[0008] Document US5114389A relates to a stair climber exercise device, including a frame, a pair of pedal arms pivotally secured to the frame, a double acting hydraulic cylinder to exert a force in opposite directions toward and away from each pedal as a result of movement of the foot of a user in opposite directions.

[0009] Documents CN220276199U and DE3727407A1 relate to stair machines or "stairmaster" machines, providing a treadmill that slopes upwards and backwards and has several steps that are activated by the weight of a person "running up".

[0010] There is need for equipment that can improve the fitness sector by creating greater satisfaction for both users and professionals.

[0011] It appears necessary, especially in large fitness centers, to intelligently provide multi-functional training machines without simultaneously requiring more space.

[0012] It is an objective of the present invention to solve drawbacks of the prior art.

[0013] In particular, it is an object of the present invention to provide a training apparatus which is improved with respect to the prior art.

[0014] A further object of the present invention is to provide a multi-functional training apparatus.

[0015] A further object of the present invention is to provide a training apparatus which is more compact.

[0016] A further object of the present invention is to provide a training apparatus which is more reliable and / or safer in its operation.

[0017] A further object of the present invention is to provide a training apparatus which is more effective in providing training features to a user.Summary of the invention

[0018] These and other objects of the present invention are achieved by a training apparatus according to the features set out in the appended claims, which are an integral part of the present description.

[0019] The training apparatus of the invention combines a treadmill machine with a stair climber machine, to create a multifunction treadmill which allows running plus stair climbing.

[0020] According to a preferred embodiment, the training apparatus comprises a frame defining a training area for a user.

[0021] The training apparatus comprises a plurality of surface elements, including active surface elements configured for supporting feet of the user during training.

[0022] The training apparatus comprises an inner rail system configured for endlessly revolving the plurality of surface elements within the frame.

[0023] The training apparatus comprises an outer rail system configured for supporting the active surface elements at a first angle with respect to the frame.

[0024] The training apparatus comprises a regulation system configured for regulating the first angle, between the surface elements and the frame.

[0025] Advantageously, it is possible to change the first angle to provide a surface for supporting the feet of the user in each active surface element, which is inclined with respect to the frame so as to form a revolving staircase. At the same time, it is possible to regulate the first angle to provide flush active surface elements, which are not inclined with respect to the frame so as to form a revolving surface, as in a treadmill.

[0026] Advantageously, the training apparatus of the present invention allows the fusion of two machines, with their respective movement tasks for the user in training, namely a treadmill and a stair machine.

[0027] Advantageously, the training apparatus of the present invention allows a higher performance of training, up to 400% more cardio fitness use thanks to the transformation from treadmill to revolving stair, with steps having variable and selectable height as function of the inclination angle of the stair.

[0028] Advantageously, the training apparatus of the present invention is more eco-sustainable, as one machine is needed instead of two, and thus less material and manufacturing are required.

[0029] Advantageously, the training apparatus of the present invention is more versatile, as it needs less space for the same functionalities.

[0030] Advantageously, the training apparatus of the present invention is more accessible to users and businesses, as the price for the purchase of two machines can be remarkably higher than the price of only one machine.

[0031] The training apparatus of the present invention allows you to optimize training performance while halving the use of equipment and space.

[0032] The training apparatus of the present invention is ideal for enthusiasts of cardio fitness activities and of interest for those athletes who practice Trail or Spartan races. The double function for training, thanks to surface elements being steps with adjustable height which can be correlated to the degree of inclination (for example 0° - 45°), is also suitable for rehabilitation of injured or sick users.

[0033] The dual system climb / run mode of the training apparatus of the invention allows steps to be flattened out in a treadmill mode or transformed into classic steps. By combining the step flattening ability with the inclination capacity between (for example around 20°) typically present on treadmills, and extending it up (for example, up to 45°) of the climb / stair machines, the apparatus allows changing the related exercise from moving flat to climbing.

[0034] Other features and advantages of the invention will be apparent from the following description of preferred embodiments, and from the claims.Brief description of the drawings

[0037] In a drawing, only one or some of a plurality of corresponding elements may be indicated by a dedicated reference numeral, to improve clarity of depiction.Detailed Description of the invention

[0038] Figure 1 shows a perspective view of a first embodiment of training apparatus 100, in a first operational mode.

[0039] The training apparatus 100 comprises a frame 101, which defines a training area 10 for a user 20.

[0040] The training apparatus 100 comprises a plurality of surface elements 102, which include active surface elements 102 which are configured for supporting the feet of the user 20 during training.

[0041] As it will be further described, the training apparatus 100 is configured for endlessly revolving the plurality of surface elements 102 within the frame 101.

[0042] In the first operational mode, the training apparatus 100 provides a revolving surface, as in a treadmill, with 0° inclination angle with respect to the horizontal floor.

[0043] Preferably, the training apparatus 100 can comprise sensors for detecting a heart rate near the console 103 or the support arms or handles 104 and an integrated system that can be connected with wearable electronic devices (not shown) for detecting / monitoring a user's heartbeat.

[0044] Figure 2 shows a perspective view of the training apparatus 100, in a second operational mode.

[0045] In the second operational mode, the training apparatus 100 provides a revolving surface, as in a treadmill, with a certain inclination angle, for example 22,5°, with respect to the horizontal floor.

[0046] The inclination angle is provided by lifting the frame 101 on one side. Preferably, the frame 101 includes a hinge 101b on one side; the frame 101 is configured to rotate around the hinge 101b by lengthening or shortening of an actuator associated to the frame and constrained to the machine, as it will be further described.

[0047] In addition, the apparatus 100 comprises handles 103, and the screen or console 103 can be mounted on these handles 104.

[0048] As it will be further described, the training apparatus 100 comprises a movable wall 105 or curtain 105, that prevents unwary users from going under the frame 101 when it is in an inclined configuration. This wall 105 is preferably composed of telescopic circular sectors, configured so that smaller ones disappear into larger ones when the inclination of the frame 101 with respect to the horizontal floor is reduced.

[0049] Figure 3 shows a perspective view of the training apparatus 100, in a third operational mode.

[0050] In the third operational mode, the training apparatus 100 provides for revolving stairs, as in a stair machine, with a certain inclination angle, for example 22,5°, with respect to the horizontal floor.

[0051] As described, the training apparatus 100 comprises a plurality of surface elements 102, which include active surface elements 102 which are configured for supporting the feet of the user 20 during training.

[0052] The training apparatus 100 is configured to provide the active surface elements 102 at a first angle with respect to the frame 101. As exemplified, the active surface elements 102 can provide steps; in the case of the third operational mode, these are low steps.

[0053] As it will be further described, the training apparatus 100 further comprises a regulation system configured for regulating the first angle of the active surface elements 102 with respect to the frame 101, to change the characteristics of the revolving steps. As it will be further described, the steps are revolved by a rail system.

[0054] Figure 4 shows a perspective view of the training apparatus 100, in a fourth operational mode.

[0055] In the fourth operational mode, the training apparatus 100 provides for revolving stairs, as in a stair machine, with a certain inclination angle, for example 45°, with respect to the horizontal floor.

[0056] As mentioned, the training apparatus 100 is configured to provide the active surface elements 102 at a first angle with respect to the frame 101.

[0057] In the case of the third operational mode, these active surface elements 102 appear as regular steps. The regulation system of the training apparatus 100 is, in fact, configured for regulating the first angle of the active surface elements 102 with respect to the frame 101, to change the characteristics of the revolving steps.

[0058] Preferably, the training apparatus 100 may provide an uphill training to the user 20.

[0059] Preferably, the training apparatus 100 may also be configured to provide a downhill training to the user 20. In this respect, the training apparatus 100 may allow reversing the direction of travel by limiting the speed of the tool (max speed 7.5 km / h) to perform downhill walking or descending of stairs.

[0060] The downhill training is relevant for the following reasons: Muscle strengthening: walking downhill requires more muscle effort than walking flat or uphill; this helps to develop and strengthen the leg muscles, including the quadriceps, calf muscles, and gluteal muscles. Coordination and control: walking downhill requires greater coordination and control of movements, as you need to stabilize your body during the descent; this helps to improve balance and stability. Endurance: walking downhill can be a great cardiovascular workout, as it requires more physical effort than walking on flat ground; this can help improve physical and cardiovascular endurance over time. Improved posture: when descending, you need to maintain good posture to avoid injury or falls; regularly walking downhill can help improve your posture and develop greater body awareness. Stress reduction: light physical activity, such as walking downhill, can help reduce stress and improve mental well-being; exercise promotes the production of endorphins, chemicals that induce a feeling of well-being and happiness. Diversified training: walking downhill can be a great alternative or complement to other forms of training, such as running or flat walking; diversified training helps engage different muscle groups and prevent adaptation and boredom.

[0061] Figure 5 shows a perspective sectional view of the training apparatus of 100, wherein the inner elements of the frame 101 are visible.

[0062] As described, the training apparatus 100 comprises a plurality of surface elements 102, including active surface elements configured for supporting feet of the user 20 during training.

[0063] The training apparatus 100 further comprises an inner rail system 201, configured for endlessly revolving the plurality of surface elements 102 within the frame 101.

[0064] The training apparatus 100 further comprises an outer rail system 202, configured for supporting the active surface elements 102 at a first angle with respect to the frame 101.

[0065] In the figures, only one of the rails of the inner rail system 201 and of the outer rail system 202 is indicated by a reference, being it clear that a pair of rails is preferably provided to support the surface elements 102. Also, there is a plurality of surface elements 102, only one of which is indicated by the reference in Fig. 5.

[0066] The training apparatus 100 further comprises a regulation system, configured for regulating the first angle between the active surface elements 102 and the frame 101, as it will be further described.

[0067] Figure 6 shows a perspective view of a surface element 102.

[0068] Preferably, all surface elements 102 of the plurality of surface elements 102 are alike.

[0069] The surface element 102 preferably comprises a top flat surface 300, configured for supporting a user's foot or feet during training; such top flat surface 300 can be appropriately sized and provide a grippy surface, such as a rubberized surface.

[0070] The surface element 102 comprises at least a first hinge 301, in the example a pair of laterally projecting first hinges, only one of them being visible. The at least first hinge 301 is configured for connecting to the inner rail system 201, preferably with a cylindrical joint, and it is carried on the inner rail, for example by a belt, a cable or a chain.

[0071] The surface element 102 comprises at least a second hinge 302, parallel and distanced from the at least a first hinge 301. By "parallel and distanced" means that the first hinge 301 and second hinge 302 provide axes which are substantially parallel and which are set out at a certain distance; this is made to ensure that the surface element 102 can remain on the trajectory defined by the inner rail system 201 and outer rail system 202 in combination, and it is also made to ensure that the surface element 102 can stably support a user's weight. In the example, there is a pair of laterally projecting second hinges, only one of them being visible. The at least a second hinge 302 is configured for connecting to the outer rail system 202, preferably by sliding within a track thereof.

[0072] Preferably, in the surface element 102, the at least a first hinge 301 is at a lower level than the at least a second hinge 302 with respect to the flat surface 300, so that the inner rail system 201 and the outer rail system 202 can support the active surface elements 102 in a flush manner in the training area, as exemplified in Fig. 5.

[0073] Preferably, a "pointed" shape of the front end 303 of the surface element 102 is provided, so as to prevent interferences between adjacent surface elements during the curved parts of the revolution within the frame 101. Of course, other geometries can be adopted.

[0074] Preferably, the surface element 102 further comprises at least one shield member 304, configured for preventing a user's foot from intruding between adjacent surface elements 102 within the revolving loop, especially when in stairs configuration.

[0075] Preferably, the at least one shield member 304 connects at least one edge 303 of the surface element 102 to at least an adjacent second surface element 102 of the plurality of surface elements 102, so as to form a "chain-like" arrangement, with displaceable configuration.

[0076] Preferably, the at least one shield member 304 comprises an elastic membrane or a plurality of hinged plates or a spring-retained rollable soft material, depending on design preferences.

[0077] The at least one shield member 304 effectively prevents the user 20 from slipping his foot between one surface element and the next. The at least one shield member 304 is suitably displaceable because the distance between the surface element 102 and the next surface element varies depending on the inclination of the first angle, and because of the curved path within the frame. Preferably, thin rigid rods can be inserted into the at least one shield member 304, to create preferential folding points.

[0078] Figure 7 shows a side view of the inner rail system 201 and of the outer rail system 202, in the first operational mode.

[0079] In the first operational mode, the inner rail system 201 and the outer rail system 202 are configured to support the active surface elements 102 in a flush manner in the training area, as also exemplified in Figure 1.

[0080] Preferably, the inner rail system 201 comprises a loop 203, configured for revolving the first hinge 301 for all the plurality of surface elements 102. A suitable motor and transmission, for example an electric motor and a revolving belt, are provided in association with the loop 203.

[0081] Preferably, the outer rail system 202 comprises a first straight guide 204, which in operation is positioned at a bottom side of the frame 101.

[0082] Preferably, the outer rail system 202 further comprises a second straight guide 205, which in operation is positioned at a top side of the frame 101.

[0083] Preferably, the outer rail system 202 further comprises a first curved guide 206 and a second curved guide 207, configured for connecting both respective ends of the first straight guide 204 and of the second straight guide 205. In this manner, the outer rail system including the first curved guide 206, the second straight guide 205, the second curved guide 207 and the first straight guide 204, defines a closed path for the at least a second hinge 302 for all the plurality of surface elements 102 revolving therein.

[0084] Figure 8 shows a side view of the inner rail system 201 and of the outer rail system 202, in the fourth operational mode 4.

[0085] In the fourth operational mode, the inner rail system 201 and the outer rail system 202 are configured to support the active surface elements 102 in an angled manner in the training area, as also exemplified in Figure 4.

[0086] Preferably, the second straight guide 205 is movable with respect to the inner rail system 201. In particular, the first angle between the active surface elements 102 and the frame 101 is varied by regulating a distance "d" between the second straight guide 205 and the inner rail system 201.

[0087] Preferably, the second straight guide 205 further comprises at least one variable linkage element, in this example a pair of variable linkage elements 208 and 209. The at least one variable linkage element 208, 209 is configured for providing a pathway to the at least a second hinge 302 within the outer rail system 202, for any position of the second straight guide 205, that is for any distance "d" between the second straight guide 205 and the inner rail system 201, as it can be appreciated by comparing Figure 7 with Figure 8.

[0088] In particular, the second straight guide 205 moves and remains parallel to an axis of the inner rail system 202, while varying the distance "d".

[0089] Preferably, the first curved guide 206 and the second curved guide 207 include respective tapered profiles, which enlarge facing towards the second straight guide 205, so as to guide the trajectory of the at least a second hinge 302 during revolving of the surface elements 102 within the frame 101.

[0090] It can be noticed, in Figure 8, that while the inner rail system 201 and outer rail system 202 are inclined, for example at an angle of 45°, together with the frame 101, the active surface elements 102 in the training area for the user can be inclined as well, of a first angle determined by a regulation system which preferably acts on the outer rail system, so that the active surface elements can be supported preferably at an angle compatible with respect to the frame, for example 45° as well, to provide a revolving staircase with horizontal steps.

[0091] In fact, preferably, the active surface elements in contact with the second straight guide 205 remain horizontal and leveled with the horizontal floor surface, i.e., inclined at 45° with respect to the frame 101, throughout their descent in revolution, until they reach the second curved guide 207.

[0092] In general, the first curved guide 206 and the second curved guide 207 provide inner and outer barriers having a greater span than the diameter of the at least a second hinge 302, leaving suitable play during this section of the revolution route.

[0093] In fact, the revolution that the surface element has to make is different depending on the inclination of the frame 101 and, calling α the angle of inclination of the frame 101, in the second curved guide 207 the step rotates (180° + α), while on the inner rail system 201 it travels an arc of circumference subtended by an angle of 180° in any configuration.

[0094] Therefore, in order to allow the surface element to properly rotate and revolute at different angles, there is provided a clearance during the curve and there are two limit curves, one corresponding to α=0°, one corresponding to α having its maximum value.

[0095] In this example, the at least a second hinge 302 is tangent to the outermost guide corresponding to α=45°. If the frame 101 is tilted at an angle less than 45°, the at least a second hinge 302 is not necessarily tangent to either rail of the second curved guide 207 for most of its curve.

[0096] However, at the end of the curve, the two curves defining the second curved guide 207 converge at the same point, as the first straight guide 204 is preferably rigidly constrained to the inner rail system 201.

[0097] The surface element 102 in contact with the first straight guide 204, which is lower in the outer rail system 202, is parallel to the frame 101 and remains parallel to the frame 101 itself, until it reaches the first curved guide 206.

[0098] This first curved guide 206 is similar to the second curved guide 207 described above, but the equation of its outer barrier is different, since the angle by which the step must rotate is (180° - α). A further difference is due to the fact that, while for the second curved guide 207 the two barriers converge, for the first curved guide 206 the two respective barriers diverge according to the revolution direction of the surface elements 102.

[0099] Therefore, the first curved guide 206 guides the pivot of the surface elements inside the upper outer guide at the end of the curve.

[0100] For this reason, the variable linkage elements 208 and 209 are provided, for example elements 208 and 209 linked by a hinge to the upper guide and with a slot at the ends of the two barriers at the end of the first curved guide 206.

[0101] These variable linkage elements 208, 209 are configured for providing a pathway to the at least a second hinge 302 from the first curved guide 206 to the second straight guide 205, for any position determined by changing the distance "d".

[0102] Figure 9 shows a side sectional view of the training apparatus 100 in the second operational mode of Figure 2; Figure 10 shows a side sectional view of the training apparatus 100 in the third operational mode of Figure 3; Figure 11 shows a side sectional view of the training apparatus 100, in the fourth operational mode of Figure 4.

[0103] Comparing these Figures 9, 10 and 11 further details of the training apparatus 100 can be appreciated.

[0104] Preferably, the frame 101 further comprises a cover element 110 configured for enclosing the first curved guide 206 and the second curved guide 207. Preferably, the cover element 110 is composed of two parts, a bottom part constrained to the second curved guide 207 and a top part constrained to the first curved guide 206, so as to reduce a height encumbrance of the frame 101 itself.

[0105] Preferably, training apparatus 100 further comprises a tilting device 111 configured for tilting the frame 101 and for providing the training area at a second angle with respect to a horizontal plane.

[0106] In general, the active surface elements 102 of the plurality of surface elements 102 are located at least in the training area supporting the user's feet.

[0107] Preferably, the first angle between the surface elements and the frame is comprised between 0° (see Figure 9) and at least 22,5° (see Figure 10), more preferably comprised between 0° (see Figure 9) and at least 45° (see Figure 11) with respect to a horizontal plane of the floor.

[0108] Preferably, all intermediate values for the first angle, i.e., ranging from 0° to 45° and more, can be selected by appropriate setting the regulation system.

[0109] Preferably, the regulation system is configured for regulating the first angle between the surface elements 102 and the frame 101 depending on the second angle of the frame 101 with respect to a horizontal plane, so as to maintain the active surface elements 102 parallel to the horizontal plane of the floor, when a stair configuration is provided.

[0110] In particular, the distance "d" between the second straight guide 205 and the inner rail system 201 can be controlled by a linear motor 210, thereby varying the inclination of the steps relative to the frame 101. A correct combination of the movement of the lifting actuator on the frame and the motion of the linear motor can be provided, to keep the steps horizontal.

[0111] Of course, when a treadmill configuration is preferred, horizontal or inclined, the distance "d" between the second straight guide 205 and the inner rail system 201 can be set to zero, and the first angle between the surface elements 102 and the frame 101 becomes 0°.

[0112] Figure 12 shows a perspective view of a second embodiment of training apparatus 100a, in the first operational mode corresponding to a treadmill at 0°, comparable to Figure 1, while Figure 13 shows a perspective view of the training apparatus 100a, in the fourth operational mode corresponding to a stair machine at 45°, comparable to Figure 4.

[0113] In general, the training apparatus 100a internally comprises the elements already described with reference to the training apparatus 100.

[0114] In particular, the training apparatus 100a comprises a frame 101 defining a training area 10 for a user 20.

[0116] In particular, the training apparatus 100a comprises an inner rail system (as element 201, not visible) configured for endlessly revolving the plurality of surface elements 102 within the frame 101.

[0117] In particular, the training apparatus 100a comprises an outer rail system (as element 202, not visible) configured for supporting the active surface elements 102 at a first angle with respect to the frame 101.

[0118] In particular, the training apparatus 100a comprises a regulation system (not visible) configured for regulating the first angle.

[0119] Preferably, the training apparatus 100a further comprises a tilting device 111 configured for tilting the frame 101 and for providing the training area at a second angle with respect to a horizontal plane.

[0120] The training apparatus 100a preferably includes support arms or handles 104b, that facilitate the user's stance, which always remain parallel to the horizontal floor, rotating with respect to the frame 101 by a suitable mechanism or actuator (not shown) according to the second angle provided by the tilting device 111.

[0121] Figure 14 shows a perspective view of a third embodiment of training apparatus 100b, in the first operational mode corresponding to a treadmill at 0°, comparable to Figure 1, while Figure 15 shows a perspective view of the training apparatus 100b, in the fourth operational mode corresponding to a stair machine at 45°, comparable to Figure 4.

[0122] In general, the training apparatus 100b internally comprises the elements already described with reference to the training apparatus 100.

[0123] In particular, the training apparatus 100b comprises a frame 101 defining a training area 10 for a user 20.

[0124] In particular, the training apparatus 100b comprises a plurality of surface elements 102 including active surface elements 102 configured for supporting feet of the user during training.

Field of the invention

[0001] The present invention relates to a training apparatus comprising a frame which defines a training area, wherein active surface elements are configured for supporting feet of the user in the training area, and wherein the surface elements can endlessly revolve in a loop.

[0002] In general, the present invention relates to exercising or physical training apparatuses, specially adapted for conditioning the cardio-vascular system, for training agility or co-ordination of movements, and for recreative purposes, in particular for indoor use.

[0003] The present invention finds preferred application in the fitness, training, and gym activity fields.Background art

[0004] The ever-increasing number of users who frequent gyms, fitness centers or physical training studios makes it difficult to train fluidly, especially at peak times where the training equipment needs to be shared among a large number of users.

[0005] This unfavorable situation often creates friction between users who have limited time to train.

[0006] There exist several types of training apparatuses, which simulate walking / running and climbing of stairs.

[0007] Document US2016367859A1 relates to a sporting apparatus comprising an endless belt disposed on a structure body, wherein the endless belt has a tilt angle for providing a gradually increased or decreased slope, so that it can rotate relative to the structure body and provide a simulated running situation in a planar road or a mountain.

[0008] Document US5114389A relates to a stair climber exercise device, including a frame, a pair of pedal arms pivotally secured to the frame, a double acting hydraulic cylinder to exert a force in opposite directions toward and away from each pedal as a result of movement of the foot of a user in opposite directions.

[0009] Documents CN220276199U and DE3727407A1 relate to stair machines or "stairmaster" machines, providing a treadmill that slopes upwards and backwards and has several steps that are activated by the weight of a person "running up".

[0010] There is need for equipment that can improve the fitness sector by creating greater satisfaction for both users and professionals.

[0011] It appears necessary, especially in large fitness centers, to intelligently provide multi-functional training machines without simultaneously requiring more space.

[0012] It is an objective of the present invention to solve drawbacks of the prior art.

[0013] In particular, it is an object of the present invention to provide a training apparatus which is improved with respect to the prior art.

[0014] A further object of the present invention is to provide a multi-functional training apparatus.

[0015] A further object of the present invention is to provide a training apparatus which is more compact.

[0016] A further object of the present invention is to provide a training apparatus which is more reliable and / or safer in its operation.

[0017] A further object of the present invention is to provide a training apparatus which is more effective in providing training features to a user.Summary of the invention

[0018] These and other objects of the present invention are achieved by a training apparatus according to the features set out in the appended claims, which are an integral part of the present description.

[0019] The training apparatus of the invention combines a treadmill machine with a stair climber machine, to create a multifunction treadmill which allows running plus stair climbing.

[0020] According to a preferred embodiment, the training apparatus comprises a frame defining a training area for a user.

[0021] The training apparatus comprises a plurality of surface elements, including active surface elements configured for supporting feet of the user during training.

[0022] The training apparatus comprises an inner rail system configured for endlessly revolving the plurality of surface elements within the frame.

[0023] The training apparatus comprises an outer rail system configured for supporting the active surface elements at a first angle with respect to the frame.

[0024] The training apparatus comprises a regulation system configured for regulating the first angle, between the surface elements and the frame.

[0025] Advantageously, it is possible to change the first angle to provide a surface for supporting the feet of the user in each active surface element, which is inclined with respect to the frame so as to form a revolving staircase. At the same time, it is possible to regulate the first angle to provide flush active surface elements, which are not inclined with respect to the frame so as to form a revolving surface, as in a treadmill.

[0026] Advantageously, the training apparatus of the present invention allows the fusion of two machines, with their respective movement tasks for the user in training, namely a treadmill and a stair machine.

[0027] Advantageously, the training apparatus of the present invention allows a higher performance of training, up to 400% more cardio fitness use thanks to the transformation from treadmill to revolving stair, with steps having variable and selectable height as function of the inclination angle of the stair.

[0028] Advantageously, the training apparatus of the present invention is more eco-sustainable, as one machine is needed instead of two, and thus less material and manufacturing are required.

[0029] Advantageously, the training apparatus of the present invention is more versatile, as it needs less space for the same functionalities.

[0030] Advantageously, the training apparatus of the present invention is more accessible to users and businesses, as the price for the purchase of two machines can be remarkably higher than the price of only one machine.

[0031] The training apparatus of the present invention allows you to optimize training performance while halving the use of equipment and space.

[0032] The training apparatus of the present invention is ideal for enthusiasts of cardio fitness activities and of interest for those athletes who practice Trail or Spartan races. The double function for training, thanks to surface elements being steps with adjustable height which can be correlated to the degree of inclination (for example 0° - 45°), is also suitable for rehabilitation of injured or sick users.

[0033] The dual system climb / run mode of the training apparatus of the invention allows steps to be flattened out in a treadmill mode or transformed into classic steps. By combining the step flattening ability with the inclination capacity between (for example around 20°) typically present on treadmills, and extending it up (for example, up to 45°) of the climb / stair machines, the apparatus allows changing the related exercise from moving flat to climbing.

[0034] Other features and advantages of the invention will be apparent from the following description of preferred embodiments, and from the claims.Brief description of the drawings

[0036] In the drawings referred to in the description, same or analogous reference numerals will designate the same or analogous elements.

[0037] In a drawing, only one or some of a plurality of corresponding elements may be indicated by a dedicated reference numeral, to improve clarity of depiction.Detailed Description of the invention

[0038] Figure 1 shows a perspective view of a first embodiment of training apparatus 100, in a first operational mode.

[0039] The training apparatus 100 comprises a frame 101, which defines a training area 10 for a user 20.

[0040] The training apparatus 100 comprises a plurality of surface elements 102, which include active surface elements 102 which are configured for supporting the feet of the user 20 during training.

[0041] As it will be further described, the training apparatus 100 is configured for endlessly revolving the plurality of surface elements 102 within the frame 101.

[0042] In the first operational mode, the training apparatus 100 provides a revolving surface, as in a treadmill, with 0° inclination angle with respect to the horizontal floor.

[0043] Preferably, the training apparatus 100 can comprise sensors for detecting a heart rate near the console 103 or the support arms or handles 104 and an integrated system that can be connected with wearable electronic devices (not shown) for detecting / monitoring a user's heartbeat.

[0044] Figure 2 shows a perspective view of the training apparatus 100, in a second operational mode.

[0045] In the second operational mode, the training apparatus 100 provides a revolving surface, as in a treadmill, with a certain inclination angle, for example 22,5°, with respect to the horizontal floor.

[0046] The inclination angle is provided by lifting the frame 101 on one side. Preferably, the frame 101 includes a hinge 101b on one side; the frame 101 is configured to rotate around the hinge 101b by lengthening or shortening of an actuator associated to the frame and constrained to the machine, as it will be further described.

[0047] In addition, the apparatus 100 comprises handles 103, and the screen or console 103 can be mounted on these handles 104.

[0048] As it will be further described, the training apparatus 100 comprises a movable wall 105 or curtain 105, that prevents unwary users from going under the frame 101 when it is in an inclined configuration. This wall 105 is preferably composed of telescopic circular sectors, configured so that smaller ones disappear into larger ones when the inclination of the frame 101 with respect to the horizontal floor is reduced.

[0049] Figure 3 shows a perspective view of the training apparatus 100, in a third operational mode.

[0050] In the third operational mode, the training apparatus 100 provides for revolving stairs, as in a stair machine, with a certain inclination angle, for example 22,5°, with respect to the horizontal floor.

[0051] As described, the training apparatus 100 comprises a plurality of surface elements 102, which include active surface elements 102 which are configured for supporting the feet of the user 20 during training.

[0052] The training apparatus 100 is configured to provide the active surface elements 102 at a first angle with respect to the frame 101. As exemplified, the active surface elements 102 can provide steps; in the case of the third operational mode, these are low steps.

[0053] As it will be further described, the training apparatus 100 further comprises a regulation system configured for regulating the first angle of the active surface elements 102 with respect to the frame 101, to change the characteristics of the revolving steps. As it will be further described, the steps are revolved by a rail system.

[0054] Figure 4 shows a perspective view of the training apparatus 100, in a fourth operational mode.

[0055] In the fourth operational mode, the training apparatus 100 provides for revolving stairs, as in a stair machine, with a certain inclination angle, for example 45°, with respect to the horizontal floor.

[0056] As mentioned, the training apparatus 100 is configured to provide the active surface elements 102 at a first angle with respect to the frame 101.

[0057] In the case of the third operational mode, these active surface elements 102 appear as regular steps. The regulation system of the training apparatus 100 is, in fact, configured for regulating the first angle of the active surface elements 102 with respect to the frame 101, to change the characteristics of the revolving steps.

[0058] Preferably, the training apparatus 100 may provide an uphill training to the user 20.

[0059] Preferably, the training apparatus 100 may also be configured to provide a downhill training to the user 20. In this respect, the training apparatus 100 may allow reversing the direction of travel by limiting the speed of the tool (max speed 7.5 km / h) to perform downhill walking or descending of stairs.

[0060] The downhill training is relevant for the following reasons: Muscle strengthening: walking downhill requires more muscle effort than walking flat or uphill; this helps to develop and strengthen the leg muscles, including the quadriceps, calf muscles, and gluteal muscles. Coordination and control: walking downhill requires greater coordination and control of movements, as you need to stabilize your body during the descent; this helps to improve balance and stability. Endurance: walking downhill can be a great cardiovascular workout, as it requires more physical effort than walking on flat ground; this can help improve physical and cardiovascular endurance over time. Improved posture: when descending, you need to maintain good posture to avoid injury or falls; regularly walking downhill can help improve your posture and develop greater body awareness. Stress reduction: light physical activity, such as walking downhill, can help reduce stress and improve mental well-being; exercise promotes the production of endorphins, chemicals that induce a feeling of well-being and happiness. Diversified training: walking downhill can be a great alternative or complement to other forms of training, such as running or flat walking; diversified training helps engage different muscle groups and prevent adaptation and boredom.

[0061] Figure 5 shows a perspective sectional view of the training apparatus of 100, wherein the inner elements of the frame 101 are visible.

[0062] As described, the training apparatus 100 comprises a plurality of surface elements 102, including active surface elements configured for supporting feet of the user 20 during training.

[0063] The training apparatus 100 further comprises an inner rail system 201, configured for endlessly revolving the plurality of surface elements 102 within the frame 101.

[0064] The training apparatus 100 further comprises an outer rail system 202, configured for supporting the active surface elements 102 at a first angle with respect to the frame 101.

[0065] In the figures, only one of the rails of the inner rail system 201 and of the outer rail system 202 is indicated by a reference, being it clear that a pair of rails is preferably provided to support the surface elements 102. Also, there is a plurality of surface elements 102, only one of which is indicated by the reference in Fig. 5.

[0066] The training apparatus 100 further comprises a regulation system, configured for regulating the first angle between the active surface elements 102 and the frame 101, as it will be further described.

[0067] Figure 6 shows a perspective view of a surface element 102.

[0068] Preferably, all surface elements 102 of the plurality of surface elements 102 are alike.

[0069] The surface element 102 preferably comprises a top flat surface 300, configured for supporting a user's foot or feet during training; such top flat surface 300 can be appropriately sized and provide a grippy surface, such as a rubberized surface.

[0070] The surface element 102 comprises at least a first hinge 301, in the example a pair of laterally projecting first hinges, only one of them being visible. The at least first hinge 301 is configured for connecting to the inner rail system 201, preferably with a cylindrical joint, and it is carried on the inner rail, for example by a belt, a cable or a chain.

[0071] The surface element 102 comprises at least a second hinge 302, parallel and distanced from the at least a first hinge 301. By "parallel and distanced" means that the first hinge 301 and second hinge 302 provide axes which are substantially parallel and which are set out at a certain distance; this is made to ensure that the surface element 102 can remain on the trajectory defined by the inner rail system 201 and outer rail system 202 in combination, and it is also made to ensure that the surface element 102 can stably support a user's weight. In the example, there is a pair of laterally projecting second hinges, only one of them being visible. The at least a second hinge 302 is configured for connecting to the outer rail system 202, preferably by sliding within a track thereof.

[0072] Preferably, in the surface element 102, the at least a first hinge 301 is at a lower level than the at least a second hinge 302 with respect to the flat surface 300, so that the inner rail system 201 and the outer rail system 202 can support the active surface elements 102 in a flush manner in the training area, as exemplified in Fig. 5.

[0073] Preferably, a "pointed" shape of the front end 303 of the surface element 102 is provided, so as to prevent interferences between adjacent surface elements during the curved parts of the revolution within the frame 101. Of course, other geometries can be adopted.

[0074] Preferably, the surface element 102 further comprises at least one shield member 304, configured for preventing a user's foot from intruding between adjacent surface elements 102 within the revolving loop, especially when in stairs configuration.

[0075] Preferably, the at least one shield member 304 connects at least one edge 303 of the surface element 102 to at least an adjacent second surface element 102 of the plurality of surface elements 102, so as to form a "chain-like" arrangement, with displaceable configuration.

[0076] Preferably, the at least one shield member 304 comprises an elastic membrane or a plurality of hinged plates or a spring-retained rollable soft material, depending on design preferences.

[0077] The at least one shield member 304 effectively prevents the user 20 from slipping his foot between one surface element and the next. The at least one shield member 304 is suitably displaceable because the distance between the surface element 102 and the next surface element varies depending on the inclination of the first angle, and because of the curved path within the frame. Preferably, thin rigid rods can be inserted into the at least one shield member 304, to create preferential folding points.

[0078] Figure 7 shows a side view of the inner rail system 201 and of the outer rail system 202, in the first operational mode.

[0079] In the first operational mode, the inner rail system 201 and the outer rail system 202 are configured to support the active surface elements 102 in a flush manner in the training area, as also exemplified in Figure 1.

[0080] Preferably, the inner rail system 201 comprises a loop 203, configured for revolving the first hinge 301 for all the plurality of surface elements 102. A suitable motor and transmission, for example an electric motor and a revolving belt, are provided in association with the loop 203.

[0081] Preferably, the outer rail system 202 comprises a first straight guide 204, which in operation is positioned at a bottom side of the frame 101.

[0082] Preferably, the outer rail system 202 further comprises a second straight guide 205, which in operation is positioned at a top side of the frame 101.

[0083] Preferably, the outer rail system 202 further comprises a first curved guide 206 and a second curved guide 207, configured for connecting both respective ends of the first straight guide 204 and of the second straight guide 205. In this manner, the outer rail system including the first curved guide 206, the second straight guide 205, the second curved guide 207 and the first straight guide 204, defines a closed path for the at least a second hinge 302 for all the plurality of surface elements 102 revolving therein.

[0084] Figure 8 shows a side view of the inner rail system 201 and of the outer rail system 202, in the fourth operational mode 4.

[0085] In the fourth operational mode, the inner rail system 201 and the outer rail system 202 are configured to support the active surface elements 102 in an angled manner in the training area, as also exemplified in Figure 4.

[0086] Preferably, the second straight guide 205 is movable with respect to the inner rail system 201. In particular, the first angle between the active surface elements 102 and the frame 101 is varied by regulating a distance "d" between the second straight guide 205 and the inner rail system 201.

[0087] Preferably, the second straight guide 205 further comprises at least one variable linkage element, in this example a pair of variable linkage elements 208 and 209. The at least one variable linkage element 208, 209 is configured for providing a pathway to the at least a second hinge 302 within the outer rail system 202, for any position of the second straight guide 205, that is for any distance "d" between the second straight guide 205 and the inner rail system 201, as it can be appreciated by comparing Figure 7 with Figure 8.

[0088] In particular, the second straight guide 205 moves and remains parallel to an axis of the inner rail system 202, while varying the distance "d".

[0089] Preferably, the first curved guide 206 and the second curved guide 207 include respective tapered profiles, which enlarge facing towards the second straight guide 205, so as to guide the trajectory of the at least a second hinge 302 during revolving of the surface elements 102 within the frame 101.

[0090] It can be noticed, in Figure 8, that while the inner rail system 201 and outer rail system 202 are inclined, for example at an angle of 45°, together with the frame 101, the active surface elements 102 in the training area for the user can be inclined as well, of a first angle determined by a regulation system which preferably acts on the outer rail system, so that the active surface elements can be supported preferably at an angle compatible with respect to the frame, for example 45° as well, to provide a revolving staircase with horizontal steps.

[0091] In fact, preferably, the active surface elements in contact with the second straight guide 205 remain horizontal and leveled with the horizontal floor surface, i.e., inclined at 45° with respect to the frame 101, throughout their descent in revolution, until they reach the second curved guide 207.

[0092] In general, the first curved guide 206 and the second curved guide 207 provide inner and outer barriers having a greater span than the diameter of the at least a second hinge 302, leaving suitable play during this section of the revolution route.

[0093] In fact, the revolution that the surface element has to make is different depending on the inclination of the frame 101 and, calling α the angle of inclination of the frame 101, in the second curved guide 207 the step rotates (180° + α), while on the inner rail system 201 it travels an arc of circumference subtended by an angle of 180° in any configuration.

[0094] Therefore, in order to allow the surface element to properly rotate and revolute at different angles, there is provided a clearance during the curve and there are two limit curves, one corresponding to α=0°, one corresponding to α having its maximum value.

[0095] In this example, the at least a second hinge 302 is tangent to the outermost guide corresponding to α=45°. If the frame 101 is tilted at an angle less than 45°, the at least a second hinge 302 is not necessarily tangent to either rail of the second curved guide 207 for most of its curve.

[0096] However, at the end of the curve, the two curves defining the second curved guide 207 converge at the same point, as the first straight guide 204 is preferably rigidly constrained to the inner rail system 201.

[0097] The surface element 102 in contact with the first straight guide 204, which is lower in the outer rail system 202, is parallel to the frame 101 and remains parallel to the frame 101 itself, until it reaches the first curved guide 206.

[0098] This first curved guide 206 is similar to the second curved guide 207 described above, but the equation of its outer barrier is different, since the angle by which the step must rotate is (180° - α). A further difference is due to the fact that, while for the second curved guide 207 the two barriers converge, for the first curved guide 206 the two respective barriers diverge according to the revolution direction of the surface elements 102.
