DESCRIPTION

MACHINE TO EXERCISE BICEPS AND TRICEPS

SECTOR OF THE TECHNIQUE

Equipment for muscular training.

BACKGROUND OF THE INVENTION

There are different types of equipment for gyms in the market depending on the exercise you want to perform.

In terms of bodybuilding exercises, most machines base their action on a chain of mechanisms that allow lifting the load when the user is operating the machine.

The concept of 'gym machine' encompasses a large number of different patents but with the same purpose. Among them, the most significant ones are highlighted and with more direct relationship with the proposed system:

• ES 0258 675 (Date: 04/06/1980 Inventor: Gert F. Koelbel)

• ES 2278 104 (Date: 09/30/2003) Inventors: Alessandri, Nerio;

Cascini, Antonio; Martini, Federico; Casagrande, Simone)

• ES 1061 811 (Date: 03/01/2006 Inventor: Cabeza Delgado, Alberto) • ES 2364 501 (Date: 06/02/2007 Inventor: Piggins, Darren)

• ES 1073 895 (Date: 25/02 / 2011.Inventor: Conesa Gracia, Xavier)

• ES 2370 325 (Date: 12/14/2011 Inventors: Holness, Wilfred)

The indicated systems are based on the exercise of various muscle groups independently.

The lifting of the load is executed through cables supported by pulleys, with the exception of ES 0258 675, which only allows exercising the muscles by means of flexion and extension without weight lifting.

Unlike the previous systems, the proposed invention allows the training of a muscle group and its antagonist in the same series of exercises. To do this, it incorporates a mechanism that automates load changes by executing the flexion and extension movements of the muscle in question.

EXPLANATION OF THE INVENTION

The machine consists of a set of elements and mechanisms that work mechanically (see Figs 1 and 2): a base part (1), which is the platform on which the machine is supported; a protective casing (2) covering the mechanism; a saddle (3) where the user sits to do the exercise; and an armrest (4), in addition to the elements that make up the automatic weight change system.

As a first step to perform the exercise on the machine, the user has to select the desired loads for each muscle before accessing the machine. Next, the user sits in the adjustable seat (3) and chooses the initial position of the grip, placing the arms on the armrest (4) properly, to work biceps or triceps. At this point, the user can start the exercise. The exercise can be finished at any time during its execution. For this it is necessary to bring the grip (5) to one of its two initial positions.

The automatic weight change system, represented in FIG. 3, is formed by the grip (5), which at one end the user grasps to exert the lifting of the weight, while the other end is attached to the shift mechanism. The attachment of this grip (5) with said mechanism consists of a rectangular piece having grooves (6), shown in Fig. 4, in order to keep both balls (7) and (8) in the proper position during the exercise. These balls (7) and (8) are connected, respectively, to the loads (9) and (10), corresponding to those of the biceps and triceps, respectively, which are independent for each muscle. The union of these two components is made by cables (11) and pulleys (12).

The execution of the exercise to work the triceps (see Fig. 3), starts with the load of the biceps (9) touching the support plate (13) and the triceps load (10) resting on the base (1). In this way, the grip (5) is in the position that allows the triceps to work (above).

At the beginning of the exercise, that is, moving the grip (5) downwards, the ball (7) that was placed in the groove of the rectangular piece (6), is pushed by a rod (14) outwards and, therefore, , when free, it moves vertically upwards. Foucault currents generated by a magnetic brake (15) in the load (9) slow down the displacement of said ball (7). At the same time, a piston (16) pushes the ball (8) corresponding to the load of the triceps (10) into the groove of the rectangular piece (6).

Finally, this ball (8) is held by this piece and, therefore, when moving the grip (5) downwards, the triceps load (10) is lifted until it reaches the support plate (13) and is activated from new the mechanism to be able to perform the exercise with the biceps.

The exercise to work the biceps begins with the triceps load (10) touching the support plate (13) and the biceps load (9) resting on the base (1). In this way, the grip (5) is in the position that allows the biceps to work (below).

At the beginning of the exercise, that is, when moving the grip (5) upward, the ball (8) that was placed in the groove of the rectangular piece (6) is pushed by a rod up (14) outwards and, for therefore, when it is free, it moves vertically downwards. Foucault currents generated by a magnetic brake (15) in the load (10) slow down the displacement of said ball (8). At the same time, a piston (16) pushes the ball (7) corresponding to the load of the biceps (9) into the groove of the rectangular piece (6).

Finally, this ball (7) is held by this piece and, therefore, by moving the grip (5) upwards, the load of the biceps (9) is lifted until it reaches the supporting plate (13) and the mechanism is activated again to be able to perform the exercise with the triceps again.

In Fig. 5, the ball exchange system can be seen in a simplified way when carrying out both the biceps and the triceps exercises. In the biceps exercise, the ball (7) is dragged down from an initial position "a" to a final position "b" by the plate (6) raising the load (9). In the triceps exercise, the ball (8) is dragged upward from an initial position "c" to a final position "d" by the plate (6) causing the load (10) to rise.

In Fig. 1, other components of the machine are also represented. To ensure that the grip (5) does not exceed the amplitude suitable for carrying out the exercise, some stops (17) are available. There is also a connection between bars (19) as a support point that allows the circular movement of the bar and a connection between the armrest and the seat (18) that secures the machine.

PREFERRED EMBODIMENT OF THE INVENTION

Among the different ways of applying this invention, a possible assembly of the machine is shown by way of example:

First of all we must take into account the space occupied by the machine. This space is determined by the distribution of the main components. The base (1), the saddle (3), the protective casing (2) that contains the automatic change mechanism and the armrest (4) together with the grip (5).

Specifically in this assembly, the housing (2) is located behind the saddle (3), and the armrest (4) together with the grip (5), are located by in front of. For this, the space required for the placement of the machine is 1 x 1.57 x 1.7 m.

Secondly, the width of the grip (5) is limited by stops (17) integrated in the joint between bars (19), which limit the grip between ± 30 °.

Finally, the maximum loads (9) and (10) to be lifted are set at 30 kg, divided into metal plates of 2 kg each. Thus, the maximum force that could be realized during the exercise would be 882 N.
