Description

DESCRIPTION

Scope of the invention

The present invention relates to the field of fitness equipment and, in particular, refers to a multifunctional apparatus for developing the muscles of the lower limbs.

More precisely, the invention can be used in the home for self-sufficient training, but it can also be used in gyms as a single tool that groups together several different machines.

Description of the technical problem

Multifunctional fitness equipment is known which allows a user, by means of alternative movements of parts of the body, to sustain training on different muscle groups by suitably modifying the configuration of the structure. The main use of multifunction equipment is generally in the home, as they allow a user, even with little experience, to carry out a diversified and movement-guided training. Another advantage is the reduced storage space required in a home environment, compared to a number of separate tools for each exercise.

With reference to the types of applications allowed by these machines, there are basically exercises for the upper part and exercises for the lower body. With reference to this last category, the multifunction equipment, used in the home, but also in gyms, are generally equipped with removable equipment that is applied to the main structure and allows exercises to be carried out to strengthen the muscles of the lower limbs.

For example, a flat bench or multifunctional equipment includes an exercise plan on which a bar substantially in the shape of an `` L '' is rotatably mounted at one end, suitable, in particular, for exercises for the lower limbs, commonly referred to as â € œLeg Extensionâ € and â € œLeg Curlâ €. In this solution, the contrasting force is generated by a series of weights, inserted in a special graft, which produce a contrasting force that opposes the muscular force applied by the user.

In other more advanced equipment, however, a pneumatic system is used which adjusts the contrast load according to the exercise to be performed.

On the other hand, in the case of gym equipment, it is a typical layout problem, choosing and arranging a number of equipment suitable for specifically training each muscle group. It is therefore taking place to set up gyms with multifunctional equipment. Even in this case, however, the machines for training the lower limbs are able to combine, in a single structure, an incomplete number of exercises so as to make it necessary to use additional equipment to allow diversified training.

It is therefore noted from what has been stated so far that the main disadvantage of multifunction equipment is that it does not allow a complete range of exercises for the lower part of the body such as to fully develop each muscle group of the lower limbs if not using a series of different and specific machines.

A further disadvantage lies in the fact that in order to change the type of exercise to be performed, a user must perform a series of manual operations such as adding or subtracting components, which modify the structure of the equipment so as to obtain a space and configuration suitable for the chosen exercise. . The result is an increase in the passive time wasted in the ideal configuration for the exercise to be performed, thus compromising the effectiveness of the entire workout.

Summary of the invention

It is therefore an object of the present invention to provide a multifunctional fitness apparatus for the musculature of the lower limbs which allows to carry out a complete, varied and effective training without having to resort to other apparatuses.

It is another object of the present invention to provide a multifunctional fitness apparatus for the muscles of the lower limbs which is constructively simple and easy to use.

It is also an object of the present invention to provide a multifunctional fitness apparatus for the musculature of the lower limbs which makes synchronous or alternating training of the lower limbs possible.

It is also an object of the present invention to provide a multifunctional fitness apparatus for the musculature of the lower limbs with high modularity such as to assume a plurality of different configurations suitable for correctly guiding the movement relating to a specific exercise for the lower part of the body.

These and other purposes are achieved by a multifunctional fitness apparatus for the muscles of the lower limbs comprising:

- an exercise surface designed to support a user in a specific exercise posture;

- a mobile support unit for supporting a lower limb able to oppose a muscular force according to a determined alternative exercise movement of said limb;

- contrast means adapted to develop a contrast force against the movement of said mobile support unit;

- a support element adapted to rotatably support said support unit and said contrast means;

characterized in that said support element is mounted to said operating surface by means of a coupling rotatable around an axis inclined with respect to said operating surface such that said support unit rotates from a first substantially vertical position to a second substantially horizontal position .

In this way, exercise movements of the lower limbs are possible both according to alternative movements in a vertical plane, and according to alternative movements in a horizontal plane, using a single equipment.

In particular, said axis of rotatable coupling between said support element and said operating surface is inclined according to a combined inclination formed by a first inclination in a plane parallel to said operating surface and a second inclination in a plane orthogonal to said operating surface, in particular said first and second inclination are obtained by means of a fixed pin integral with a frame of said operating surface, in which said pin has an axis and is a rotation seat for said support element around said axis .

Advantageously, means are provided for locking the rotation of said support element in said pin according to a plurality of reference points, in particular, said reference points allow to arrange said support element from said first substantially vertical position to said second substantially position horizontal.

In particular, said first inclination is comprised between 80 ° and 100 °, preferably between 85 ° and 95 °, in particular between 88 ° and 92 °; while said second inclination is comprised between -10 ° and 10 °, preferably between -5 ° and 5 °, in particular between -2 ° and 2 °.

Preferably, the multifunctional apparatus provides two specular multifunctional units, symmetrically arranged on opposite sides to said operating surface, each comprising said support unit, said contrast means and said support element, in particular said contrast means are pneumatically connected. In this way, the exercise can be performed by moving the limbs in unison or alternatively. In the first case, the compression of the cylinders is simultaneous, therefore the available volume, for example, of air in the circuit is greatly reduced and the pressure rises consistently with the volume reduction. In the second case, the two cylinders are compressed alternately, and each cylinder acts as a tank to the other. The volume of air in the circuit is therefore reduced less than in the previous case and the pressure consequently increases to a lesser extent. This results in a contrasting action of the lower cylinders. Having said that, the athlete can start the exercise according to the first modality, that is by moving the legs in unison, until fatigue brings him in conditions of not being able to continue further. At that point, without having to interrupt the exercise, he can continue with the second mode, that is the alternate one, in which the contrasting action is lighter. Exercise with decreasing load is a very effective technique especially for weight loss or increase in muscle tone and endurance.

In particular, said support element comprises a first and a second rectilinear portion and a connecting portion that joins said rectilinear portions in such a way as to form a determined angle between said first rectilinear portion and said second rectilinear portion, in particular, said angle à It is comprised between 20 ° and 30 °, preferably between 15 ° and 18 °, in particular, between 10 ° and 12 °.

Advantageously, said first rectilinear portion of said support element is inclined with respect to said axis of said pin according to an angle between 3 ° and 15 °, preferably between 5 ° and 10 °, in particular, between 7 ° and 9 ° .

Advantageously, said support unit comprises:

- a disk for transmitting said reciprocating operating movement rotatably connected to said support element;

- a thrust element connected integrally to said transmission disk;

- a plurality of application points for said contrast element arranged on said transmission disk.

Advantageously, said thrust element has a movable support portion able to pass from a positioning configuration, in which the user is facilitated in positioning himself on said operating surface, to an operating configuration, in which the user can perform the desired training, said thrust element being entirely integral with said disc and in particular, said thrust element comprises a support arm integral with one end of said transmission disc at the other end of which said movable support portion is present , which is able to move from said operating configuration to said positioning configuration while remaining in a plane substantially orthogonal to said support arm.

In particular, said contrast means comprise a rectilinear contrast element having a first end rotatably connected to said support element and a second end rotatably connected to said transmission disk in correspondence with a determined application point, in particular said rectilinear element the contrast device is connected by means of mutual engagement to said transmission disk, in correspondence with said application point. For example, a pin protruding from said second end of said actuator which engages in a hole made on said application point. In this way, if you want to perform an extension exercise, the contrast media are connected to the disc so as to oppose this extension exercise, while if you want to perform a flexion exercise, the contrast media are connected to the disc so as to oppose this extension. flexion exercise.

Advantageously, said plurality of application points is distributed along a concentric circumference with said transmission disk and, in particular, each application point corresponds to a specific type of exercise to be performed.

Description of a preferred embodiment

In Figure 1, a multifunctional fitness apparatus 10 suitable for developing the muscles of the lower limbs comprises an exercise surface 1 suitable for supporting a user 30 (visible in Figures 6 to 18) in a determined exercise posture. In particular, the operating surface 1 provides a fixed part 13 with respect to a frame 7, and a movable part 12 which can be tilted with respect to the part 13. In this way the user 30, depending on the exercise to be performed, can assume a correct posture by leaning on the mobile part 12 without burdening the back muscles that are particularly stressed in this type of exercise. The apparatus 10 according to the invention also includes a rotatable support unit 20, adapted to oppose a muscular force of a lower limb according to a determined alternative exercise movement, contrast means 3, adapted to develop a force against the movement of the mobile support unit 20 and a support element 2 adapted to rotatably support the support unit 20 and the contrast means 3. More precisely, the support element 2 is mounted to the operating surface 1 by means of a coupling rotatable about an axis 8 inclined with respect to the operating surface 1 such that the support unit 20 rotates from a first substantially vertical position 50 to a second substantially horizontal position 60 (visible, for example, in Figure 13) .

In this way, exercise movements of the lower limbs are possible both according to alternative movements in a vertical plane, and according to alternative movements in a horizontal plane, using a single equipment.

Figure 2 schematically shows the arrangement and orientation of the axis 8 with respect to the operating surface 1. In particular, the pivotal coupling axis 8 between the support element 2 and the operating surface 1 is inclined according to at a first inclination 8 'in a plane parallel to the operating surface 1 and on the basis of a second inclination 8' 'in a plane orthogonal to the operating surface 1. The first 8' and the second 8 '' inclination are obtained by means of a fixed pin 4 integral with the frame 7 and, in particular, with a connecting portion 5 of the operating surface 1 which acts as a rotation seat for the support element 2.

In particular, the first inclination is between 80 ° and 100 °, preferably between 85 ° and 95 °, in particular between 88 ° and 92 °; while the second inclination is comprised between -10 ° and 10 °, preferably between -5 ° and 5 °, in particular between -2 ° and 2 °.

More precisely, the pin 4 is mounted integral with the connection portion 5 which, in the representation of figure 1, is provided in two different positions with respect to the operating surface 1. In this way, the equipment 10 can adapt appropriately at user height 30 thus allowing correct positioning and exact exercise.

In addition, means are provided for locking the rotation (not shown) of the support element 2 on the pin 4 according to a plurality of reference points so as to substantially allow the arrangement of the support element 2 from the first vertical position 50, to the second position 60 horizontal.

Figure 1 also shows the contrast means 3 which comprise a rectilinear contrast element 3 'having a first end rotatably connected to the support element 2 and a second end, shown in detail in Figure 3, rotatably connected to a transmission disc 6 at a specific application point 16.

In particular, figures 3 and 4 show an enlargement of the support unit 20, respectively according to a front and rear view, which comprises the disk 6 for transmitting the alternating operating movement rotatably connected to the support element 2 and an element of thrust 27 (shown, for example, in Figures 6 and 7) integrally connected to the transmission disk 6. Furthermore, the transmission disk 6 has a plurality of application points 16 for connecting the contrast element 3 '. A specific type of exercise to be performed is associated with each application point 16. Advantageously, the plurality of application points 16 is distributed along a concentric circumference with the transmission disk 6 so that, in order to perform an extension exercise, the contrast means 3 are connected to the disk 6 so as to oppose this exercise of extension. extension, while wanting to perform a flexion exercise, the contrast means 3 are connected to the disc 6 so as to oppose this flexion exercise.

More precisely, the straight contrast element 3 'is connected to the transmission disk 6, in correspondence with one of the application points 16, by means 21 of mutual engagement represented, in the present embodiment, by a protruding pin 17 which is engages in a hole 16 representing the point of application. Furthermore, as always shown in figures 3 and 4, a handle 15 is provided which allows the user to vary the connection point with the transmission disk 6. In a constricting example, the protruding pin 17 is opposed by a spring (not shown) in such a way that, in use, it cannot exit hole 16. As a result a user by means 21 can simply and quickly switch from one exercise configuration to another so as to reduce downtime training that distinguish known multifunction equipment.

In addition, as shown in figures 13 and 14, the multifunction apparatus 10 provides two specular multifunction units, symmetrically arranged on opposite sides with respect to the operating surface 1, each comprising the support unit 20, the contrast means 3 and the support element 2. In particular, the contrast means 3 are pneumatically connected.

In this way, the exercise can be performed by moving the limbs in unison or alternatively. In the first case, the compression of cylinders 3 is simultaneous, therefore the available volume, for example, of air in the circuit is greatly reduced and the pressure rises consistently with the volume reduction. In the second case, the two cylinders 3 are compressed alternately, and each cylinder 3 acts as a tank to the other. The volume of air in the circuit is therefore reduced less than in the previous case and the pressure consequently increases to a lesser extent. This results in a contrasting action of the lower cylinders. Having said that, the athlete 30 can start the exercise according to the first modality, that is by moving his legs in unison, until fatigue brings him in conditions of not being able to continue further. At that point, without having to interrupt the exercise, he can continue with the second mode, that is the alternate one, in which the contrasting action is lighter. Exercise with decreasing load is a very effective technique especially for weight loss or increase in muscle tone and endurance.

Figure 5 shows a side view of the fixture 10 which highlights the relative arrangement of the pin 4 with respect to the support 2. The main purpose of this arrangement is to allow the passage from the configuration 50 in which the thrust element 27 rotates according to a vertical plane, suitable for exercises such as â € œLeg Extensionâ € and â € œLeg Curlâ €, to configuration 60, in which the thrust element 27 rotates according to a horizontal plane, used to train the adductor and abductor muscles of the legs . In addition, in this representation a rod 19 is visible which is adapted to support the movable part 12 of the operating surface 1 in an inclined position.

With reference to the components of the multifunction equipment 10, as shown in Figure 5, the thrust element 27 has a movable support portion 25 able to pass from a positioning configuration (not shown), in which the user 30 is facilitated in positioning himself on the exercise surface, to an exercise configuration, in which the user 30 can carry out the desired training. In particular, the thrust element 27 is entirely integral with the transmission disk 6 and comprises a support arm 24 integral with one end of the transmission disk 6 at the other end of which there is the mobile support portion 25, which It is able to move from the operating configuration to the positioning configuration while remaining in a plane substantially orthogonal to the support arm 24.

With reference to figures 6 to 16, the different types of exercise for the lower limbs are schematically shown, which can be performed through the multifunction equipment 10, according to the invention.

Figure 6 shows the configuration of the equipment 10 for an exercise designed to strengthen the quadriceps femoris muscle. The starting position 32 of the exercise sees the user 30 sitting on the surface 1 with the lower part of the leg, more precisely the area around the ankle, in contact with the arm 25 of the thrust element 27. From this starting position according to an extension movement 31 the user 30 applies a muscular force such as to cause the element 27 to rotate until it reaches a position 33, visible in Figure 7, in which the leg is substantially parallel to the exercise surface 1. The alternating movement of this exercise is represented by the passage in sequence from position 32 to position 33 by means of the extension movement 31 in which the contrasting element 3 'contracts, opposing a resistance to the movement 31 of the user 30. Similarly, the phase in return, ie from position 33 to position 32, it offers resistance due to the pneumatic force exerted by the contrast media 3. The exercise can also be carried out by alternating the two limbs. In this case, the resistance offered by the pneumatically connected contrast media 3 will be reduced and will be useful, for example, for a phase of muscle relaxation in training.

Figure 8 shows a front view of the equipment 10 where the user 30 is in the rest position 32, of Figure 6, in which the optimal position of a single multifunction unit with respect to the operating surface 1 is highlighted. , in figure 8 the particular shape of the support element 2 can be seen. In fact, the latter comprises a first 2 'and a second 2' 'rectilinear portion and a connecting portion 2' '' (visible in figure 18) which joins the rectilinear portions in such a way as to form a determined angle between the first rectilinear portion 2 'and the second rectilinear portion 2' '. A more explanatory view of this construction detail is shown in figure 18 described later.

In particular, the angle is comprised between 20 ° and 30 °, preferably between 15 ° and 18 °, in particular, between 10 ° and 12 °. Furthermore, the first rectilinear portion 2 'of the support element 2 is inclined with respect to the axis 8 of the pin 4 according to an angle between 3 ° and 15 °, preferably between 5 ° and 10 °, in particular, between 7 ° and 9th.

Figure 9 shows the exercise setup for training the hamstring. In this case the user 30 is arranged on the exercise surface 1 in a lying position with the head facing downwards. The lower limb in the rest position 33 'is in contact with the thrust element 25, as in the previous case, in the ankle area but, in this case, the foot is turned in the opposite direction. In carrying out a flexion movement 35, visible in figure 10, the leg rotates around the knee joint and brings the pushing element 27 to the final position 34. By carrying out the movement 35 in the opposite direction, the muscle is returned to the non-contracted position also in this case counteracting the return pneumatic force of the contrast media 3.

Figure 11, on the other hand, represents another type of exercise which can be carried out according to the rotation plane 50. This type of movement stimulates the gluteus muscles together with those of the abdomen. The exercise sees the user 30 in a position 36 extended over the exercise surface 1, with the inner part of the leg, in correspondence with the knee, in contact with the pushing element 25. According to an extension movement 37 the leg moves to position 38 substantially parallel to the operating plane 1. As shown in figures 11 and 12, the rectilinear contrast element 3 'opposes the movement by contracting and rotating around the support 2.

Figures 13 and 14 show a top view of the equipment 10, in the configuration 60 of the unit 20 which rotates according to the horizontal action plane in which both multifunction units are located below the operating surface 1. In this configuration Two exercises are possible for antagonist muscles of the leg such as adductors and abductors.

In particular, figures 13 and 14 show the configuration for developing the adductor muscles according to a flexion movement 39 in which the user 30, in the seated position visible laterally in figure 18, comes into contact with the external part of the thigh with the thrust element 27 which represents the initial position 41. By carrying out the movement 39, opposed by the contrast means 3, the user 30 arrives in a position 42 in which the legs are substantially parallel to each other. The contrast effect is also present in the release phase, i.e. in the phase that brings it back to the starting position 41.

Vice versa in Figures 15 and 16, the equipment 10 and in particular the means 3 oppose a bending movement 40 such that the user in the starting position 43 passes to the contraction position 44 opposed by the pneumatic force. Again, the release phase completes the alternating exercise movement.

Figure 17 shows a bottom view of the multifunction equipment 10 in which the position of the support unit 20 below the operating surface 1 is highlighted. It is stored in a home space when not in use. In fact, the overall dimensions of the equipment 10 are considerably reduced with respect to the configuration 50 (visible in Figure 5) in which the support unit is positioned according to the vertical plane.

Figure 18 shows the equipment 10 in side view in the movement configuration 60 where the mobile part 12 of the exercise surface 1 is inclined by means of the rod 19 in a position such as to support the back during one of the exercises at the adductors or abductors described above.

Furthermore, the constructive form of the support element 2 is graphically visible with the first portion 2 'connected by means of a connecting portion 2' 'to the second portion 2' '. This feature allows rotation from the vertical position 50 to the horizontal position 60 as well as the correct positioning of the two multifunction units with respect to the operating surface 1.

An important feature of this multifunctional apparatus 10 is that of allowing, as previously described, both simultaneous and alternating limb training. This function is given by the pneumatic connection of the two contrast means 3 which allow the user 30 to carry out a cool-down action in all types of exercise without varying the load but only by performing an alternating movement of the limbs. Such an aspect is not present in known equipment which, on the other hand, requires an interruption of the exercise and a postponed restart once the load has been reduced so as to jeopardize its effect.

The above description of a specific embodiment is able to show the invention from a conceptual point of view so that others, using the known technique, will be able to modify and / or adapt this specific embodiment in various applications without further research. and without departing from the inventive concept, and, therefore, it is understood that such adaptations and modifications will be considered as equivalent to the specific embodiment. The means and materials for carrying out the various functions described may be of various nature without thereby departing from the scope of the invention. It is understood that the expressions or terminology used have a purely descriptive purpose and therefore not limitative.
