Description

A generally skeletal muscle exercise device that enables muscle activity of the lower limbs and upper limbs and the use of the device

The present invention relates to the technical field of a muscle exercise device in the form of an elliptical or oval form, which in particular allows muscle activity of the lower limbs and upper limbs.

This type of ring or round type of device is known to have a single axis and two directions of deformation along a steel or carbon fiber or fiberglass circle. These devices are impedance ring type devices that generally enable the movement of lower limbs and upper limbs.

They make it possible to improve muscle performance and build muscle, or just improve the body form (especially by the "Pilates" method).

A disadvantage of these prior devices is that the user can only apply a single type of force, which will always be the same unless an auxiliary impedance mechanism (such as a "Sandow") or Strip)).

Another disadvantage is that they are made of expensive materials and can include multiple components (such as a curved part of a round circle, handles, "Sandow", etc.), which causes their production. It is quite complicated and therefore increases the production cost of the device.

The technical problem caused: there is a real need here to develop a device that allows at least two muscles to exercise in the lower limbs and upper limbs by providing at least two possibilities of force, which can be easily produced, and It can be made at a reduced cost.

The present invention relates to a device, particularly for exercising the upper and lower limbs, having at least two impedance forces, and preferably three forces. These forces were obtained without the addition of an auxiliary component and without any special adjustment.

The present invention is therefore directed to a device that specifically permits exercise of the upper and lower limbs (chest muscles, triceps, abdominal muscles, back muscles, and muscles of the calves and thighs, as well as other muscle groups, etc.).

The invention relates to a device having a substantially elliptical shape (1) and having two laterally extending portions (4, 5) of the "ear" type, the extensions in particular allowing them to be used The person is grasping. The device also includes two strips (6, 7) that are thinner than the other main strip, which form the assembly of the device (2, 3, 4, 5). The two thin strips are formed on the elliptical extension formed by the device and thus pass through the extensions and connect the points A and B/C and D.

Because of the elliptical shape of the device, all of the curved members formed thereon are slightly curved toward the outside. The radius of the primary strip and the radius of the "ear" type laterally extending portion are preferably 120 millimeters, although it will be appreciated that this dimension can be designed to meet the needs of those skilled in the art.

Preferably, the device is a one-piece injection molded plastic (PA6 (polyamide nylon 6)). Advances in the technology that has been created in plastic materials have made it possible to obtain materials with a relatively substantial memory effect, but in order to highlight this memory effect, it is possible to place a steel strip on the inside of the plastic, and this is also Provides greater impedance.

In addition, the synthetic materials have the following characteristics: good traction resistance, flexural ability, good impact resistance, high mechanical strength, rigidity, hardness, good fatigue resistance and abrasion resistance; or can be used by those skilled in the art Any other material that is readily available, which will make it possible to produce this type of device in a single component with high strength and a substantial memory effect so that the part can be restored to its original form, regardless of the applied deformation. And the device can be used for a long time often while still providing the best quality of use during its use.

In order to make the assembly stronger, it is possible to add a reinforced element (9) at the position where the applied tension is strongest, that is, at a height substantially at the apex of the bend (e, f) and at the strips The height of the joint (A, B, C, D) is added to the reinforced element (9).

The device has a size of approximately 50 cm in diameter. For the thick portion (2, 3, 4, 5), the strip of the device has a thickness of about 7 mm, and for the thinner portion (6, 7), the thickness of the strip of the device is about 4 mm.

According to a preferred embodiment of the device (Fig. 7), the dimensions are as follows: diameter 51 cm and strip width 5 cm.

According to a preferred embodiment, the height of the top of the four arcs formed by the main strips (2, 3, 4, 5) of the device, i.e., at the top (2), lateral side (4) , 5) (the extension of the ear pattern), and the height of the lower (3) part, which may be placed with an additional comfortable molding (8) which is made of an elastomer ( Or polyethylene or polyurethane foam) to make it easy to be gripped and used.

According to the preferred embodiment (Fig. 7), the device comprises a total of ten elements of the additional comfortable molded part pattern (8) and the reinforced type (9).

According to another embodiment of the invention, the additional molding is preferably ergonomic in order to improve the usability of the device.

The material used can be of any type that is readily available to those skilled in the art such that it ensures that the user has a good handle and a good support at the height of the leg.

It may be based on the position at which the user grasps the device, and thus exerts different impedance forces depending on where the user applies pressure: - low impedance force, by only being on the lower (3) part and above (2) The height of the component grasps the device (Fig. 2); - the intermediate impedance of the impedance, which is between the two elliptical and extended members, that is, at the junction of the different strips (A+C) The height of (D+B) grasps the device (Fig. 4); - a strong impedance force that grasps the device at the height of the thin strips (6 and 7) (Fig. 5); - very strong Impedance force that grasps the device by the height of the laterally extending portions (4, 5) of the "ear" pattern (Fig. 3); - "twisting" by virtue of the "ear" pattern The height of the laterally extending portions (4, 5) grips the device and is brought against each other by means of the extensions (Fig. 6).

When the device is grasped at the height of the lower (3) member and the upper (2) member, and the pressure is applied toward the inside of the device (by the pressure indicated by the arrows in the drawings), the thin The strips (6 and 7), which are curved toward the outer side, move with this without providing any impedance.

On the other hand, when the device is grasped at the height of the laterally extending members (4, 5) and the same type of pressure is applied towards the interior, the thin strips (6 and 7) are stretched, thus This creates an increased impedance that is opposite to the applied pressure.

When the device is grasped at the height of the joints (A and C) or (B and D) and pressure is applied toward the interior, the deformation of the thin strips creates an intermediate impedance force.

When the device is grasped at the height of the thin strips (6, 7) and pressure is applied toward the inside, a strong impedance force is exerted. In addition, the device begins to oscillate and tremble by a certain pressure applied by the user, that is, about 80% of the maximum force that can be applied (due to the weight distribution, especially the "ear". The result of the weight distribution of the laterally extending portion of the pattern), and thus the vibration transmitted to the muscles of the forearm.

Different impedance forces are obtained by the variation of the thickness of the different strips and by the deformation of the strips connecting A to B and C to D.

Referring to Figures 9 through 12, the test is performed on the device according to the present invention by progressively compressing the device on a force measuring platform (as during its recommended use) and sampling at 100 Hertz (Hz). The results are as follows (in kilograms): - low impedance force: average load at maximum compression of 14 kg, with a maximum load of 16.2 kg applied; - intermediate impedance force: maximum at 13.1 kg The average load under compression, with a maximum load of 15.2 kg applied; - strong impedance force: average load at maximum compression of 17.5 kg, with a maximum load of 18.5 kg applied; - very strong impedance Force: The average load at a maximum compression of 20.2 kg with a maximum load of 22.6 kg applied.

These tests show that for the device according to the invention, the impedance is progressively increased as the device is compressed until it reaches a maximum "plateau".

For comparison purposes, a load measurement (in kilograms) is also performed during the "sit-up" exercise (moving in a prone position, holding a support weight bar that extends the arm up above the torso And causing the rod to contact the torso and then raising it at a time) and having a load that approximates the maximum load produced by the device according to the invention.

It can be noted that for this "sit-up push motion" (see Figure 8), the impedance force is actually the greatest from the beginning of the movement, and then decreases slightly as the load is pushed in.

Thus, when causing such identical muscles (these breast muscles) to act, a better result is obtained by using the device according to the invention than by performing a supine press movement (for the same weight).

It should be understood that those skilled in the art will know how to modify the impedance forces according to the desired application.

As such, it is possible to perform various exercises that are applicable to each individual (from the occasional user to the skilled user) without the use of different devices and without any adjustments.

In general, it is possible to provide means having dimensions different from those described in this application, provided that they will make it possible to retain all of the technical features of the device. In fact, it may be advantageous to provide smaller devices (such as those designed for children) or, on the other hand, may be larger depending on the application and motion to be performed. It is also possible to modify the reinforced part and the gripping element.

Example of use of the device according to the invention:

Example 1:

By holding the device according to the invention in the hand with the lateral extensions (4 and 5) of the "ear" version, placing the elbows at the height of the components (3 and 2), and facing inwards Pressing the elbows, the activities performed effectively act on the large chest muscles.

Example 2:

By holding the thin strips (6 and 7) in the hand and stretching our arms to almost maximum while applying pressure towards the interior of the device, the activities performed effectively act on the chest muscles. The vibrations obtained by this position during continuous exercise will make it possible to even further improve the activity on these chest muscles.

Example 3:

When sitting on the ground, the knee is placed on the device according to the invention at the height of the joints (A or C or D or B) and supported on the ground and open its legs outwards, while the activity The leg is stretched out of the muscles.

These are just a few examples of the many possible uses of the device according to the invention, which cannot all be listed, since the application of the device is extensive.
