DESCRIPTION

MUSCULATION BENCH

OBJECT OF THE INVENTION

The present invention relates to a bodybuilding bench, intended to be marketed among manufacturers of gym machinery for later use in sports centers.

BACKGROUND OF THE INVENTION

Weight-building benches are currently known, which comprise a structure with a support surface for the back and buttocks, and a lifting bar, on which weights are attached.

There are two designs for these weight benches, also known as press-benches, which are the free weight and the Multipower. In the case of the free bench press, there is a support where the bar with the weights is placed and the user lifts them freely, which can cause the possible fall of the bar with the weight on the user in case of failure in lifting .

In the case of the Multipower, the movement of the bar is guided vertically, which can cause muscle injuries as it is not a natural movement, since it moves completely in a straight line due to the fact that the bar is fixed to rails, when in the free movement lifting is done with a slight degree of curve. In addition, this machine prevents the wobble of the bar, thus avoiding working the stabilizer muscles, doing a less effective job.

For this reason, these two types of machine present problems in terms of safety, incomplete muscular work or possible injuries, which is solved with the bodybuilding bench of the invention.

DESCRIPTION OF THE INVENTION

The bodybuilding bench of the invention is of the type that comprises a structure with a support surface for the back and buttocks, and a lifting bar independent of the structure, and according to the invention it comprises, in its most generically expressed embodiment:

-some resistant elastic elements that are related to the lifting bar with the structure (directly or indirectly, either by coupling to the structure itself or to a common support surface of the structure) to prevent the lifting of the bar from causing the movement of others components,

-where the elastic resistant elements comprise tension regulators to regulate the resistance when stretched, and

-where the tension regulators comprise a release button, to eliminate their traction force.

In addition, supports for the bar or other auxiliary elements can be arranged in the structure.

In this way, the workload is graduated by regulating the resistance against stretching of the elastic resistant elements, and the need to use mobile disc weights is avoided, so guides for the bar are not required as in the multipower bench press, and in case of failure in elevation, the load on the bar can be instantly or gradually released simply by pressing the button, for example with the foot, avoiding accidents and injuries.

With the invention there are at least three improvements in the field of security:

-In case of not being able to perform the lift, a large part of the weight is subtracted, so that the user can place the bar on its supports without the risk of it falling on him, avoiding different injuries.

-Since the use of weight discs is not necessary, back injuries are also avoided when placing or removing the weight. This also increases the comfort of use, due to the fact that it is not necessary to place the discs, saving time and inconvenience during their exchange. It also results in added comfort for workers in the sports centers, since they have to place fewer discs in their respective compartments.

-as there are no rails, the movement can be carried out naturally, in addition to allowing the stabilizers to work due to the effort to avoid the wobble of the bar.

PREFERRED EMBODIMENT OF THE INVENTION

Starting with fig. 1, it can be seen how the bodybuilding bench (1) of the invention is of the type comprising a structure (2) with a support surface (3) for the back and buttocks, and a lifting bar (4), and according to with the invention comprises:

- elastic resistant elements that are found relating the lifting bar (4) to the structure (2), for which the bar (4) comprises in this case specific hooks (44),

-where the elastic resistant elements comprise tension regulators, and -and where the tension regulators comprise a release button (53).

Very preferably, the elastic resistant elements comprise elastic bands (51), where the tension regulators also comprise rollers (52) thereof to regulate their length and therefore their resistance when stretched. In this case, the reels 52 (see Figs. 2 and 3) can comprise a spool 52a and a brake 52b, the brake 52b being associated with the release button 53. This has the advantage of being able to automate the regulation of the resistance, and for this the invention, in this embodiment, has provided that the rotation of each spool (52a) is driven by a motor (54) -through a worm coupling (54a) crown (54b) for example-, and controlled by an electronic control unit (56) with a user interface (57) (see also fig. 1) to regulate the tension of the corresponding elastic band (51) in a comfortable and precise way. For this specific embodiment, it is preferred that the brake (52b) comprises (see Fig. 2) an electrically actuated closing clamp (52ba) and arranged at the outlet of the reel (52a) on both sides of the corresponding elastic band (51). , the button (53) being associated with an electrical circuit (53a) for activating the closing or opening of the clamp (52ba). This allows the braking or blocking to be applied directly to the resistant element, increasing safety. This electrical circuit can be found implemented in the electronic control unit (56).

By using integrated elastic bands, its regulation allows offering different resistance in order to save time in changing weight, selecting the load through the electronic control unit (56), avoiding dangers when training alone, because in case of emergency all the resistance can be eliminated by activating the button (53) with the foot.

The lifting bar (4) is ideally a 1520 mm Olympic bench press bar. long and with a diameter of 28 m. Some supports (100) have been provided on the structure (2) for the same, the bar (4) being independent of the structure, as seen in fig.

one.

It is preferred that the winders (52) are arranged in pairs (55), where each pair (55) comprises a winder (52) arranged on each side of the lifting bar (4) - to ensure that the tension on both sides of the bar is the same-, ideally comprising three pairs (55) of rollers (52), where each pair (55) comprises elastic bands (51) of 1.5 meters length (stretchable up to 3 meters) and where the bands of each pairs have the same elastic constants (resistance to stretching) and the bands of different pairs ideally have different elastic constants, since in this way the load in units of kilos can be precisely regulated.

As indicated, it is preferred that the button (53) is arranged in the area where the user's feet are placed, during the use of the bodybuilding bench (1).

Finally, indicate that it is preferred that the support surface (3) of the back and buttocks lack a folding backrest, to be able to perform the exercise inclined and declined, in addition to the normal horizontal position.

Having sufficiently described the nature of the invention, it is indicated that the description of the same and of its preferred embodiment should be interpreted in a non-limiting way, and that it covers all the possible variants of embodiment that are deduced from the content of this report. and the claims.
