Description

A substantially clover-shaped weight training apparatus

  muscular work of the lower and upper limbs.

  TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical sector of elliptical or oval-shaped weight training apparatuses allowing, among other things, the muscular work of the lower and upper limbs.

Prior art:

  Circular, ring, or circle type devices are known to deform on a single axis and two directions of a circle made of steel or carbon fibers or glass fibers. These are resistance ring type devices, essentially allowing the lower and upper limbs to be exercised. They allow (among others thanks to the Pilates method) to improve the muscular yield and to tone the muscles or simply to improve the physical form.

  A disadvantage of these prior devices is that the user can only perform one type of force, which will always be the same, unless an additional strength of resistance (for example, a bungee or strap) is used which requires a setting. Another disadvantage is that they are made of expensive materials and that they can be made up of several parts (for example, two arcs of assembled circles, handles, bungees, etc.) making the relatively complex and increasing manufacture of this material. makes the cost of producing the material. Technical problem posed: There is a real need to develop a device allowing the bodybuilding among other lower and upper limbs by offering at least two possibilities of strength, which can be easily achieved, and can also be manufactured at reduced cost.

  SUMMARY OF THE INVENTION The present invention relates to a device of the body-building apparatus type, in particular upper and lower limbs, having at least two resistance forces, preferably three forces. These forces being realized without the addition of an additional piece, and without any particular adjustment. Detailed description of the invention

  The invention thus relates to a device for the bodybuilding in particular of the lower and upper limbs (pectorals, triceps, abdominal, back, and muscles of the legs and thighs ...).

  Figure 1 is a top view of the device according to the present invention, in a rest position.

  Figure 2 is a view of the same device where a first (weak) force is applied. Figure 3 is a view of the same device where a second (strong) force is applied.

  Figure 4 is a view of the same device where a third (intermediate) force is applied. The invention relates to a device of substantially oval shape (1) which has two lateral extensions (4, 5) of type ears allowing, inter alia, its grip by a user. This device also comprises two strips (6, 7) of smaller thickness relative to that of the other main band forming the entire device (2, 3, 4, 5). These two thin strips are formed on the extension of the oval created by the device, thus passing through said extensions, and connect the points AetB / Cet D. All the curved parts formed on this device, because of its oval shape, are slightly curved outwards. The radius of the main bands and lateral extensions of the ear type is preferably 120 mm, but this dimension can of course be adapted to the requirements of the skilled person. This device is preferably a monoblock piece of injected plastic (PA 6 (polyamide nylon 6) .The technological progress concerning plastic materials makes it possible to obtain relatively important memory effect materials, but to accentuate the memory effect it is possible to place a steel band inside the plastic, this also to provide more resistance.

  In addition, the composite materials have the following characteristics: good tensile strength, bending capacity, good impact resistance, high mechanical strength, stiffness, hardness, good resistance to fatigue and wear; or by any other material accessible to those skilled in the art for making such a device in one piece, having a high rigidity and a large memory effect so that the piece can return to its original shape whatever the deformation applied and that the device can be used regularly over time by always offering optimal use qualities over time.

  In order to bring greater strength to the assembly, it is possible to provide reinforcement-type elements, at the places where the tensions applied are the strongest, that is to say essentially at the level of the vertex points. curvature (e, f) and at the junction points of the bands (A, B, C, D).

  Said device has a dimension of about 50 cm in diameter. The width of the strips of the device is about 7 mm for the thick portions (2, 3, 4, 5) and about 4 mm for the thinnest portions (6, 7). According to a preferred embodiment, it is possible to place at the vertices of the four arcs formed by the main band of the device (2, 3, 4, 5), that is to say at the level of the upper parts (2), lateral (4, 5) (ear-type extensions) and lower (3), a comfortable overmolding elastomer (or polyurethane foam or polyethylene) facilitating its grip and its use.

  According to yet another embodiment of the present invention, this overmoulding is preferably ergonomic in order to improve the use of the device. The material used can be of any type accessible to those skilled in the art, as long as it can guarantee the user a good grip and a good support in the legs.

  It is possible to exert different resistance forces depending on the places by which the user grasps said device, and therefore according to the places where the user applies the pressures: - low, by grasping the device simply at the level of the lower parts (3) and upper (2), - strong, grasping the device at the level of the lateral extensions of type ears (4, 5), - intermediate by grasping the device between the two parts of oval and extension, c ' that is to say at the junction points of the different bands (A + C) (D + B). When the device is grasped at the lower (3) and upper (2) portions, and pressure is applied towards the inside of the device (pressure represented by arrows in the figures), the thin strips ( 6 and 7) (due to their outward curvature) accompany the movement without offering any resistance. On the contrary, when the device is grasped at the lateral extension parts (4, 5), and the same type of pressure is applied inwards, said thin strips (6 and 7) are tend, creating increased resistance against applied pressure. When the device is grasped at the junction points (A and C) or (B and D), and inward pressure is applied, the deformation of said thin strips creates an intermediate resistance force. Different resistance forces are obtained by varying the thickness of the different bands and blocking the deformation with thin strips connecting A to B and C to D. Thus, it is possible to perform various exercises. , adapted to everyone (from the occasional user to the experienced user), without using different devices and without making adjustments. It is quite possible to provide devices having other dimensions than those described in the present application, as long as they allow to keep all the technical characteristics of said device. Indeed, it may be advantageous to provide smaller devices (for example for children) or on the contrary larger for the applications and exercises that you want to perform. The invention also covers all the embodiments and all the applications which will be directly accessible to the person skilled in the art upon reading the present application, and of his own knowledge.
