Description

The invention relates to a muscle strengthening bar and to a muscle strengthening assembly comprising such a muscle strengthening bar.

Sports equipment is often specific to a specific function or exercise. Exercise opportunities are therefore often limited.

This is particularly the case in the area of muscle building.

We know weight training bars called "Pump" bars having two ends on which variable disc-shaped weights are mounted.

They are used in group classes in fitness rooms. These are muscle strengthening classes of the same name: “Pump”. A "Pump" bar typically measures between 130 cm and 132 cm and up to 140 cm. The bar is 28mm in diameter.

The space in the center of the bar is dedicated to the different possible hand placements. It measures between 98 cm and 1 m.

The end parts of the bar that can carry the weights measure between 15 cm and 16 cm. They are intended to receive the weights and disc stops preventing them from falling. Document US 9844696B2 describes a portable exercise device that allows a person to perform Pilates-like exercises.

We also know suspended pull-up bars attached to two lateral supports or to a ceiling allowing pull-up work using body weight.

However, these pull-up bars only allow you to perform one type of physical exercise and only strengthen a restricted part of the body.

In addition, these bars do not allow them to adapt to a very wide range of different user levels, nor to a very wide range of difficulties.

And then, using a barbell with weights can cause trauma to the joints, especially for beginners. This tool is not suitable for beginners or people with a low level.

The aim of the invention is therefore to overcome the disadvantages of the prior art by proposing a muscle strengthening bar allowing several types of exercises to be carried out at the same time, in a progressive manner to avoid joint trauma and adapted to all levels. .

The invention relates to a muscle strengthening bar comprising a central gripping portion separating a first end intended to receive a first weight and a second end intended to receive a second weight.

According to the invention, the muscle strengthening bar comprises a first fixing means and a second fixing means positioned symmetrically with respect to the central gripping part. Each fixing means is positioned between one of the ends and the central gripping part and is intended to be connected to one end of a rope.

The invention thus provides a modular muscle strengthening bar which offers a wider range of bodybuilding techniques and maximum adaptability to all audiences likely to use it (young, elderly, beginners or experienced practitioners).

The muscle strengthening bar brings together several bar strength training techniques in a single tool.

This equipment offers more possibilities than a simple weight bar or a simple pull-up bar, with the added possibility of using additional elastics.

The use of elastics makes it possible, in a first case, to facilitate the exercise for beginners, in a second case, to add difficulty for experienced practitioners, and in a third case, to do muscular work exclusively with elastics. . This last method is the least traumatic for the joints (intended for people wanting to train in a gentler way).

The muscle strengthening bar comprises a third fixing means and a fourth fixing means positioned symmetrically with respect to the central gripping part. Each of the fixing means is positioned between one of the ends and the central gripping part and is intended to be connected to one end of an additional rope.

The invention thus makes it possible to produce several bodybuilding variants.

It allows its user to practice classic bodybuilding with weights or elastic bands or by suspending body weight with straps.

It also allows you to combine the three previous working methods or functions with each other (weights, elastics and suspension with straps).

It is possible to use the cast iron with one or two elastics (for more difficulty) or the suspension system with elastics or straps to help the beginner progress.

The combination of these three strength training methods (weights, suspension and elastics) allows a wider choice of muscle strengthening exercises with the same bar.

Advantageously, the fixing means are fixed on the muscle building bar adjacent to the ends so as to form a stop for the weights when they are mounted on the muscle building bar.

The fixing means thus have a dual function, allowing fewer elements to be used.

Preferably, the fixing means are each formed of an element in the form of an arch (or trigger guard) extending in the direction of the central axis and comprising two legs welded to the muscle strengthening bar.

The orientation of the arch-shaped elements in this direction has the function of being able to hang carabiners there, without these being hindered by the weights resting against the arch-shaped elements when the muscle strengthening bar is loaded. In fact, the arch-shaped elements also serve as disc stops or stops to prevent the weights (cast iron discs) from sliding towards the center of the muscle strengthening bar.

Advantageously, the first fixing means and the third fixing means are mounted in opposition and symmetrically with respect to the central axis of the muscle strengthening bar. The second fixing means and the fourth fixing means are mounted in opposition and symmetrically with respect to the central axis of the muscle strengthening bar.

This improves the locking of the weights.

The first fixing means is offset relative to the third fixing means. The second fixing means is offset relative to the fourth fixing means. The first fixing means and the second fixing means are mounted in rotation relative to the muscle strengthening bar and around the central axis. The third fixing means and the fourth fixing means are fixedly mounted on the muscle strengthening bar.

The rotational movement provides comfort during strength training exercises.

During a rotational movement, the muscle strengthening bar tends to rotate in the palm of the hand, unless you squeeze it very strongly at the risk of forming blisters on the hands.

For greater comfort, the two attachment points for the elastic rotate freely around the muscle strengthening bar to facilitate rotational movements.

Advantageously, the muscle strengthening bar comprises a stop fixed thereto and adjacent to each end. The first fixing means and the second fixing means are positioned adjacent to the stops to limit the movement of these fixing means in the direction of the central axis.

Alternatively, the first fixing means is formed by a first orifice and the third fixing means is formed by a second orifice. The first and second orifices are positioned on the same first cylindrical support. The second fixing means is formed by a third orifice and the fourth fixing means is formed by a fourth orifice. The third and fourth orifices are positioned on the same second cylindrical support. Each cylindrical support includes a central hole through which the muscle strengthening bar passes.

Preferably, the muscle strengthening bar comprises a first removable end and a second removable end removably fixed to the central gripping part by first holding means.

It is thus possible to reduce the size of the muscle strengthening bar during transport thanks to this bar disassembly system.

This makes it easier to transport the muscle building bar by dismantling the removable ends which are intended to support the weights. This makes it easier to store in a storage bag or car trunk.

Advantageously, the muscle strengthening bar comprises a first bar portion fixed to a second bar portion in a removable manner by second holding means.

This makes it possible to further reduce the bulk of the muscle strengthening bar for its transport.

The invention also relates to a muscle strengthening assembly comprising a muscle strengthening bar as defined above and at least one muscle strengthening accessory mounted or fixed on the muscle strengthening bar.

The muscle strengthening accessory comprises a first weight mounted on a first end of the muscle strengthening bar and a second weight mounted on a second end of the muscle strengthening bar and/or at least one elastic rope fixed on the first means of fixing and/or on the second fixing means and/or an additional non-elastic rope fixed to the third fixing means and a second additional non-elastic rope fixed to the fourth fixing means.

• [ Fig.12 ] schematically illustrates a muscle strengthening bar comprising two removable ends and a central gripping part comprising two detachable parts.

There figure 1 represents a muscle strengthening bar 1 extending longitudinally along a central axis 12. The muscle strengthening bar 1 has a central gripping portion 3 separating a first end 2a intended to receive a first weight 7a and a second end 2b intended to receive a second weight 7b.

The muscle strengthening bar 1 has a rectilinear tubular shape and is made of metal. It has a cylindrical shape. It can be hollow or solid.

For example, the muscle strengthening bar 1 can be a steel tube 28 mm in diameter and 2 mm thick. It measures between 130 cm and 132 cm and up to 140 cm, corresponding to a standard “Pump” bar.

The central gripping part 3 is dedicated to the different possible hand placements. She measures between 98 cm and 1 m.

The ends 2a, 2b of the muscle strengthening bar 1 which can carry the weights 7a, 7b, measure between 15 cm and 16 cm long.

The dimensions of this muscle strengthening bar 1 are ideal for the successful execution of various exercises. In addition, the length is suitable to provide a small bodybuilding equipment that is practical to carry.

According to the invention, the muscle strengthening bar 1 comprises a first fixing means 4a and a second fixing means 4b positioned symmetrically with respect to the central gripping part 3. The first fixing means 4a is positioned between the first end 2a and the central gripping part 3. The second fixing means 4b is positioned between the second end 2b and the central part of grip 3.

The central gripping part 3 is centered on the muscle strengthening bar 1.

The first fixing means 4a is intended to be connected to a first end 6a of a rope 5a, 5b. The second fixing means 4b is intended to be connected to a second end 6b of this rope 5a, 5b.

The rope 5a, 5b may or may not be elastic. For example, it can be a strap or an elastic rope.

There figure 2 describes an example in which the rope 5a, 5b is an elastic 5a, 5b. This rope 5a, 5b has two ends 6a, 6b connected respectively to the first and second fixing means 4a, 4b by carabiners 28 or equivalent.

This configuration allows you to perform “back pull” exercises.

Alternatively, the two ends 6a, 6b of a first elastic rope 5a can be connected to the first fixing means 4a and the two ends 6a, 6b of a second elastic rope 5b can be connected to the second fixing means 4b, as illustrated on the Figure 7 .

This allows you to obtain a longer elastic length and to perform “squat” exercises.

According to another variant of use, it is possible to use two elastics 5a, 5b of the same tension mounted in series, including a first elastic 5a having a first end 6a attached to the first fixing means 4a and a second end 6b attached to a first end 6a of a second elastic 5b. The second end 6b of the second elastic 5b is hooked to the second fixing means 4b.

The use of two elastics allows you to increase the range of movement and preserve the ideal tension corresponding to each exercise. Another use is to avoid causing the elastic to break when it is used alone during large amplitude movements.

As illustrated on the figure 1 , the muscle strengthening bar 1 also comprises a third fixing means 8a and a fourth fixing means 8b positioned symmetrically with respect to the central gripping part 3. The third fixing means 8a is positioned between the first end 2a and the part central gripping part 3. The fourth fixing means 8b is positioned between the second end 2b and the central gripping part 3.

The third fixing means 8a is intended to be connected to a first end 23a of a first additional rope 9a. The fourth fixing means 8b is intended to be connected to a first end 23b of a second additional rope 9b.

The additional ropes 9a, 9b may be elastic or not. Preferably, each additional rope 9a, 9b is a strap.

Alternatively, the muscle strengthening bar 1 may include only the first and second fixing means 4a, 4b or only the third and fourth fixing means 8a, 8b.

The fixing means 4a, 4b, 8a, 8b are adjacent to the respective ends 2a, 2b of the muscle strengthening bar 1 so as to form a stop for the weights 7a, 7b when they are mounted on the ends 2a, 2b of the muscle strengthening bar 1.

If the muscle strengthening bar 1 only includes the first and second fixing means 4a, 4b, only the latter form a stop for the weights 7a, 7b.

The weights 7a, 7b preferably have a disc shape and an orifice into which the ends 2a, 2b of the muscle strengthening bar 1, of circular section, are inserted.

The weights 7a, 7b have a first face 24 which is in contact with the fixing means 4a, 4b, 8a, 8b.

The weights 7a, 7b have a second face 25, opposite the first face 24, which is in contact with a disc stop 26.

As illustrated in the examples of figures 1 to 4 , the fixing means 4a, 4b, 8a, 8b are preferably formed of an arch-shaped element 10, such as a trigger guard.

The arch-shaped elements 10 may be a “U”-shaped ring. Other shapes are possible such as semi-circular shapes.

Each arch-shaped element 10 comprises two legs 27 welded to the muscle strengthening bar 1. The arch-shaped elements 10 extend along the central axis 12 of the muscle strengthening bar 1.

The orientation of the arch-shaped elements 10 in this direction has the function of being able to hang carabiners 28 there, without these being hindered by the weights 7a, 7b pressing against the arch-shaped elements 10 when muscle building bar 1 is loaded. Indeed, the arch-shaped elements 10 also serve as disc stops or stops to prevent the weights 7a, 7b (cast iron discs) from sliding towards the center of the muscle strengthening bar 1.

The arch-shaped elements 10 of the first fixing means 4a and the arch-shaped elements 10 of the third fixing means 8a are mounted in opposition and symmetrically with respect to the central axis 12 of the muscle strengthening bar 1 .

Likewise, the arch-shaped elements 10 of the second fixing means 4b and the arch-shaped elements 10 of the fourth fixing means 8b are mounted in opposition and symmetrically with respect to the central axis 12 of the bar. muscle strengthening 1.

The four arch-shaped elements 10 form four attachment points allowing the rope 5a, 5b and two additional ropes 9a, 9b to be hung at the same time, as illustrated in the Figure 3 . Two attachment points are formed above the muscle reinforcement bar 1 and two attachment points below the muscle reinforcement bar 1 (relative to the plane of the muscles). figures 1 to 4 ).

Preferably, the rope 5a, 5b is an elastic rope or an elastic 5a, 5b. The additional rope 9a, 9b is non-elastic like a suspension strap, for example.

This allows the use of the muscle strengthening bar 1 in suspension. The advantage compared to a conventional fixed pull-up bar is to be able to use height-adjustable straps 9a, 9b.

The primary purpose of this use with straps 9a, 9b is to be able to do exercises other than pull-ups thanks to the possibility of choosing the height of the bar.

The second purpose of the straps 9a, 9b is to be able to adapt to all levels of practice, depending on the height adjustment.

For example, an advanced practitioner will set the muscle strengthening bar 1 high to perform his pull-ups in order to have his feet in the air, while a beginner practitioner will lower the height of the muscle strengthening bar 1 to learn how to do his pull-ups feet on the ground, playing on the inclination of the body to regulate the difficulty.

Adaptability is the main advantage of this material.

The muscle strengthening bar 1 offers another interesting possibility in suspension.

In fact, its four attachment points make it possible to suspend the muscle strengthening bar 1 and add an elastic band 5a, 5b to help you progress in certain exercises, as shown on the Figure 3 .

Finally, the third goal of using the muscle strengthening bar 1 with straps 9a, 9b is to be able to hang anywhere and without worrying about the ceiling height.

The muscle strengthening bar 1 can be used suspended on a beam, a branch or any other solid support.

There Figure 3 represents an example in which the muscle strengthening bar 1 is used in suspension with two fixings 29a, 29b fixed each on two opposite walls 30a, 30b. Each fixing 29a, 29b comprises a plate 31a, 31b equipped with a hooking ring 32a, 32b.

More practically, the hanging rings 32a, 32b can be replaced by carabiners.

The aim of this improvement is to allow everything to be put away at the end of training, to be able to unhook the straps 9a, 9b as well, quickly, and without changing their adjustment each time.

Alternatively, and as shown on the figures 5 to 7 , the first fixing means 4a is formed by a first orifice 16a and the third fixing means 8a is formed by a second orifice 17a. The first and second orifices 16a, 17a are positioned on the same first cylindrical support 14a.

The second fixing means 4b is formed by a third orifice 16b and the fourth fixing means 8b is formed by a fourth orifice 17b. The third and fourth orifices 16b, 17b are positioned on the same second cylindrical support 14b.

Each cylindrical support 14a, 14b comprises a central orifice 15a, 15b crossed by the muscle reinforcement bar 1 and separating the orifices 16a, 17b.

Each cylindrical support 14a, 14b is fixed to the muscle strengthening bar 1.

The cylindrical supports 14a, 14b also serve as stops for the weights 7a, 7b.

Alternatively and as illustrated on the figures 8 to 12 , the first fixing means 4a is offset relative to the third fixing means 8a. The second fixing means 4b is offset relative to the fourth fixing means 8b.

According to a preferred embodiment and as shown on the figures 8 to 12 , the first fixing means 4a and the second fixing means 4b are mounted in rotation relative to the muscle strengthening bar 1 and around the central axis 12. The third fixing means 8a and the fourth fixing means 8b are fixedly mounted on the muscle strengthening bar 1.

The muscle strengthening bar 1 comprises two stops 13a, 13b fixed to the muscle strengthening bar 1 and each adjacent to one of the ends 2a, 2b. The first fixing means 4a is positioned between a first stop 13a and the third fixing means 8a and is contiguous to the latter to limit the transverse movement of the first fixing means 4a in the direction of the central axis 12.

Likewise, the second fixing means 4b is positioned between a second stop 13b and the fourth fixing means 8b and is contiguous to the latter to limit the transverse movement of the second fixing means 4b in the direction of the central axis 12.

Each stop 13a, 13b has a cylindrical shape with a central orifice crossed by the muscle strengthening bar 1.

As illustrated on the figure 8 , the fixing means 4a, 4b, 8a, 8b are formed of an element in the form of an arch 10 or “U”-shaped ring. Other shapes are possible such as semi-circular shapes.

Each arch-shaped element 10 comprises two legs 27 welded to a washer 33 of cylindrical shape with a central orifice crossed by the muscle strengthening bar 1.

The arch-shaped elements 10 extend along the central axis 12 of the muscle strengthening bar 1.

This improvement provides comfort during bodybuilding exercises thanks to the rotational movement.

According to a preferred method of use illustrated on the Figure 9 , the first mobile fixing means 4a is connected to a first end 6a of a rope 5a, 5b which is in this example an elastic 5a. The second mobile fixing means 4b is connected to a second end 6 of this rope 5a, 5b.

The third fixed fixing means 8a is connected to a first end 23a of a first additional rope 9a. The fourth fixing means 8b is connected to a first end 23b of a second additional rope 9b.

In this example, the first and second additional ropes 9a, 9b are formed from two straps 9a, 9b.

Connections are made via 28 carabiners.

During a rotational movement, the muscle strengthening bar 1 tends to rotate in the palm of the hand, unless you squeeze it very hard at the risk of blisters forming on the hands.

For greater comfort, the two attachment points for the elastic 5a, 5b rotate freely around the muscle strengthening bar 1 to facilitate rotational movements.

Two fixed attachment points for the strap 9a, 9b are retained for stability during suspended exercises and two movable attachment points for the elastic 5a, 5b are then provided for more comfortable use with the elastics 5a, 5b when the muscle strengthening bar 1 is hung on a support by the straps 9a, 9b.

According to a possible variant illustrated on the figures 10 And 11 , the muscle strengthening bar 1 comprises a first removable end 19a and a second removable end 19b removably fixed to the central gripping part 3 by first holding means 20. The first removable end 19a and the second removable end 19b can remove from the muscle strengthening bar 1.

There Figure 10 represents first holding means 20 comprising a thread 34 formed on the second removable end 19b which is intended to be screwed into a threaded orifice 35 provided at one end 36 of the central gripping part 3.

Alternatively and as illustrated on the Figure 11 , the first holding means 20 comprise a nesting system with square tubes and fixing by pins.

The second removable end 19b comprises a tubular portion 37 of square section which fits into a housing of square section 38 provided at one end 36 of the central gripping part 3.

The tubular portion 37 comprises an orifice 39. The third and fourth fixing means 8a, 8b also comprise an orifice 40. When the tubular portion 37 of the second removable end 19b is inserted into the square section housing 38 of the central part of gripping 3, a pin 41 is inserted into these two orifices 39, 40 aligned to block the second removable end 19b on the central gripping part 3 of the muscle strengthening bar 1.

The square tube has the advantage of facilitating assembly/disassembly. With a square tube, the holes 39, 40 are always aligned to insert the pins 41 without difficulty (without having to look for the correct alignment of the holes as is the case with circular sections).

It is thus possible to reduce the size of the muscle strengthening bar 1 during transport thanks to this bar disassembly system.

This makes it possible to transport the muscle strengthening bar 1 more easily by dismantling the removable ends 19a, 19b which are intended to support the weights 7a, 7b. This makes it easier to store in a storage bag or car trunk.

As said before, the muscle building bar 1 measures between 130 cm and 140 cm long. The first and second removable ends 19a, 19b each measure between 15 cm and 20 cm long.

After disassembly, the central gripping part 3 of the muscle strengthening bar 1 measures less than one meter.

A bar approximately one meter long fits the width of a car trunk while a bar 140 cm long does not fit.

According to another embodiment illustrated on the Figure 12 , the muscle strengthening bar 1 comprises a first bar portion 21 fixed to a second bar portion 21' in a removable manner by second holding means 22.

The second holding means 22 may be identical to the first holding means 20.

The second holding means 22 may comprise a thread formed on the first bar portion 21 which is intended to be screwed into a threaded orifice provided at one end of the second bar portion 21'.

Preferably and as illustrated on the Figure 12 , the second holding means 22 comprise a nesting system with square tubes and fixing by pins.

A first portion of bar 21 comprises a tubular portion 42 of square section, opposite the associated end portion 2, which can be fitted into a housing of square section 43 provided at one end 44 of a second portion of bar 21', opposite to the associated end part 2.

The tubular portion 42 comprises an orifice 45. The second bar portion 21' also comprises an orifice 46. When the tubular portion 42 of the first bar portion 21 is inserted into the square section housing 43 of the second bar portion 21 ', a pin is inserted into these two aligned orifices 45, 46 to fix the two bar portions 21, 21' together.

The combination of this assembly/disassembly system of two bar portions 21, 21' with removable ends 19a, 19b makes it possible to further reduce the bulk of the muscle strengthening bar 1 for its transport.

The different fixing means described above can be combined.

Alternatively, it is also possible to use this assembly/disassembly system of two bar portions 21, 21' with fixed, non-removable ends 2a, 2b.

The invention also relates to a muscle strengthening assembly comprising a muscle strengthening bar 1 as defined above and at least one muscle strengthening accessory mounted or fixed on the muscle strengthening bar 1.

The muscle strengthening accessory may comprise a first weight 7a mounted on a first end 2a of the muscle strengthening bar 1 and a second weight 7b mounted on a second end 2b of the muscle strengthening bar. muscular reinforcement 1 and/or at least one elastic rope 5a, 5b fixed to the first fixing means 4a and/or to the second fixing means 4b and/or a first additional non-elastic rope 9a fixed to the third fixing means 8a and a second additional non-elastic rope 9b fixed to the fourth fixing means 8b, as described previously.
