Description

OBJECT OF THE INVENTION

The present invention, as expressed in the statement of this specification, refers to an apparatus for doing gymnastics that basically comprises a frame formed by legs and an armor that integrates between its elements two parallel stringers where a carriage is guided mobile that moves against the resistance of tension-working springs connected at one end to the mobile carriage while opposite ends of the springs are connected to a crossbar, so that to make use of the apparatus of the invention, a user rests his body on the mobile car and the feet on a crossbar. In this situation, when the user stretches the legs he does so against the resistance of the springs.

Starting from this premise, the objective of the invention is to achieve a variable regulation of the springs in each of the several initial positions of the mobile car, so that the user can start the physical exercise being the springs in an initial position without any tension and also the springs can be placed with different elongations in multiple positions with different tensions, which opens a wide range of possibilities for the user.

Another particular feature of the invention is centered on collateral sliding characteristics in which the ends of the crossbar are fixed where the ends of the springs are connected, so that these collateral slides allow a smoother and more precise displacement of the crossbar. length of the frame reinforcement stringers.

BACKGROUND OF THE INVENTION

At present, different gymnastics devices are known, among which those that comprise an armor that has two parallel stringers in which a mobile car associated with a crossbar is guided by means of springs, so that during the exercise A user rests his body on the mobile car and his feet on a crossbar. In this situation, when the user stretches the legs he does so against the resistance of the springs, exercising his legs and also other parts of his body.

The patent with publication No. US 5681249 consists of an apparatus for doing gymnastics where the assembly of the mobile carriage and crossbar associated by means of the springs can be initially placed in different positions along the parallel stringers thanks to which the ends of the crossbar can be placed in different pairs of recesses established in side plates fixed to the stringers of the reinforcement. This armor also integrates a fixed stop where it supports one end of the mobile car in its only initial resting position.

Patent with publication No. EP 1774993 consists of a gymnastic apparatus that basically performs the same functions as the apparatus described in the previous paragraph, highlighting that the crossbar where the user's feet rest can be placed at different heights.

The patent with publication No. EP 1691899 consists of another gymnastic apparatus which in principle has a basic structure as described above, where the stops to limit its single resting position consist of extensions attached to the crossbar in which they engage the ends of the springs

Thus, these three documents cited have the limitation that the mobile car has a single initial resting position by incorporating fixed stops, reducing this fact the possibilities of gymnastic devices, also presenting the limitation that the tension of the springs It can only be regulated considering a single initial position of the mobile car versus the regulation of the springs in multiple initial positions of the mobile car in the present invention.

DESCRIPTION OF THE INVENTION

In order to achieve the objectives and avoid the inconveniences mentioned in the previous sections, the invention proposes an apparatus for doing gymnastics that comprises an armature that integrates between its elements two parallel stringers that have guides through which a mobile carriage moves in against the resistance of springs that work on traction and are connected at one end to the mobile carriage while the opposite ends of the springs are connected to a crossbar that can be placed in different stable positions.

The apparatus of the invention further comprises movable skates that can be placed in different stable positions along guide rails fixed to the frames of the armature; where said movable skates constitute the top of the movable car in different initial positions with variation of the tension of the springs.

The crossbar is connected at its ends to slides coupled to the guide rails through which they travel, thus being able to position the crossbar in different stable positions.

The positions of the slides and the mobile skates along the guide rails are fixed by first and second elastic pins that are introduced through opposite holes located in the slides, mobile skates and guide rails.

The stringers of the reinforcement integrate internal fins arranged above the guide rails; where said internal fins constitute the support of rollers of the mobile carriage, and where said internal fins constitute an additional guide of the sliding and sliding skates.

The sliding and sliding skates integrate grooves into which the internal fins integral with the stringers of the reinforcement are fitted.

The mobile skates integrate elastic elements against which the mobile car stops when it is located in the respective initial rest position. In an embodiment of the invention, the mobile car stops against the elastic elements of the mobile skates through the most advanced sheaves of said mobile car.

The apparatus of the invention includes at least one scale to precisely control the positions of the movable skates and also the slides; where said scale is fixed to one of the stringers of the armor.

On the other hand, it should be noted that with the apparatus of the invention it is possible to exercise sport discipline with different lengths of springs, which further expands the potential of the equipment of the apparatus of the invention.

DESCRIPTION OF AN EXAMPLE OF REALIZATION OF THE INVENTION

Considering the numbering adopted in the figures, the gymnastics apparatus contemplates the following nomenclature used in the description:

1.-Legs. 2.-Armor. 3.-Stringers. 4.-Mobile car. 4th-Hooks. 5.-Springs. 6.-Crossbar. 6a.-Hooks 7.-Internal fins. 8.-Rollers. 9.-Guiding rails.

10.-Sliding.

1Oa.-Slots. 11.-First elastic pins. 12.-Mobile skates. 12a.-Slots. 13.-Second elastic pins. 14.-Elastic elements. 15.-Scale.

It comprises a frame formed by legs (1) and an armor (2) that integrates between its elements two parallel stringers (3) where a mobile carriage (4) moves in against the resistance of springs (5) that work under tension and are connected at one end to the mobile carriage (4) while the opposite ends of the springs (5) are connected to a crossbar (6), so that to make use of the apparatus of the invention, a user rests his body on the mobile carriage (4) and the feet on a crossbar not shown in the figures. In this situation, when the user stretches the legs does so against the resistance of the springs (5), thus exercising the legs and other parts of the user's body.

The stringers (3) of the reinforcement (2) integrate internal fins (7) by which it is guided the mobile car (4) by means of rollers (8) integrated in said mobile car (4).

In some extreme sections of the stringers (3) of the reinforcement (2) and below the internal fins (7), guide rails (9) are attached to which the cross member (6) is attached by means of slides (10) that can be placed in multiple positions stable along said guide rails (9) by means of first pins elastics (11) that are introduced by pairs of holes facing the slides (10) And guide rails (9).

Movable skates (12) are also attached to the guide rails (9) they can place in different stable positions through a few seconds elastic pins (13) that are also introduced by pairs of facing holes of the mobile skates (12) and guide rails (9), so that the mobile carriage (4) in its several initial positions butt against elastic elements (14) integrated in said mobile skates (12).

Thus, the movement of the mobile skates (12) allows the mobile carriage (4) to be placed in different initial positions according to several initial positions of the mobile carriage (4), unlike what happens conventionally where the mobile car can only be place in a single initial position as it rests against stops that are fixed and does not displace bies such as the movable skates (12) of the invention at hand.

Another advantage achieved with the invention at hand is that in each of the possible positions of the mobile carriage assembly (4), springs (5) and crossbar (6), it is possible to regulate the tension of the springs (5) through the movement of the mobile skates (12).

The mobile skates (12) integrate the elastic elements (14) where the rollers (8) more advanced of the mobile carriage (4) stop when it is located in the respective initial rest position.

On the other hand, both the slides (10) and the mobile skates (12) integrate, respectively, grooves (10a), (12a) into which the internal fins (7) on which the mobile carriage (4) runs ) by means of the rollers (8).

It should be noted that above the internal fins (7), scales (15) are provided to precisely control the positions of the movable skates (12) and also the slides (10).

Finally, the ends of the springs (5) are anchored to hooks (4a), (6a) connected, respectively, to the mobile carriage (4) and to the crossbar (6) whose ends are connected to the slides (10).
