Description

DESCRIPTION

Tower for machines to perform physical exercise

TECHNIQUE SECTOR

The present invention refers to an accessory or tower for physical exercise machines, commonly called "reformer", with the aim of incorporating the technique used in physical exercises such as Pilates, usually practiced in the ground, to a more intense workout.

More specifically, the accessory is materialized in a kind of vertical tower, which can be of greater or lesser height, and which is linked to one of the ends of the main frame in order to increase the number of exercises possible to perform with the machine.

The object of the invention is to provide a device in which the accessories that participate in it, adjustable along the vertical bars of the tower, can be safely immobilized, without risk of accidental angular displacements for them.

BACKGROUND OF THE INVENTION

Machines for physical exercise are known in which a horizontal frame participates with longitudinal guides through which a carriage can move against the tension of some springs, a frame that includes a support bar for feet or hands, as well as a structure or vertical tower with a series of accessories to increase the number of exercises possible to perform with the machine.

The trolley is movable through the support of different parts of the body, offering a great versatility of exercises, some of which are related to the elements or accessories that are linked to the tower.

These accessories must be able to be adjusted in height, for which the tower is made up of two vertical props, of greater or lesser height, with a circular section, through which a bushing or cylindrical support is movable, to which the accessories are externally linked. in question, so that said bushing or support is stabilized at the desired height by means of a grub screw.

The problem with this system is that the bushing or support is susceptible to turning on the prop itself, since both are cylindrical, which can cause an incorrect arrangement of the accessories linked to the bushings, which can negatively affect the performance. of the corresponding exercises.

EXPLANATION OF THE INVENTION

The tower for machines to carry out physical exercise that is recommended satisfactorily solves the problem previously exposed, based on a simple but effective solution.

For this, starting from the conventional structure described above, the invention focuses on the fact that the tower props have a polygonal section, preferably octagonal, complementary to the internal section of the bushings that constitute the supports for the accessories of the tower. tower, which prevent relative rotation between these supports and the corresponding props.

In this way, it is possible to ensure at all times the correct relative position of the supports within the tower and consequently of the accessories associated with it, such as folding "U" bars against turnbuckles, or other conventional accessories. .

From this structure, an extremely versatile and precise machine is achieved, ideal for performing a large number of physical exercises, such as Pilates, with a greater physical intensity, achieving better results.

BRIEF DESCRIPTION OF THE DRAWINGS

To complement the description that is going to be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of its practical embodiment, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:

Figure 1.- Shows a top-side perspective view of a machine for physical exercise that includes a tower made in accordance with the object of the present invention, in this case of considerable height, although said tower could also be of lower height.

Figure 2.- Shows a perspective detail of one of the tower props, where the octagonal section of said vertical prop can be seen.

Figure 3.- Shows a sectional detail of the upright at the level of one of the height-adjustable supports along one of the tower uprights.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the physical exercise machine of the invention is made up of a rectangular horizontal frame (1), equipped with legs (3) at its ends, whose beams (2) include guides for horizontal displacement of a car (4), which includes shoulder supports, frame (1) that has an adjustable foot bar (5) in correspondence with one of its ends, counting on its opposite end with a tower (6 ) with a series of accessories to carry out other types of exercises, so that said accessories are linked to the props (9) of the tower by means of supports (10) stabilized by means of grub screws (12), and the props can be joined horizontally by one or more crossbars (13).

These accessories, merely by way of example, can materialize in a "U" bar (7) articulated with respect to its own supports (10) through which it is linked to the struts (9), and which tends to a horizontal arrangement, being attached both above and below the ends of its middle branch by means of respective springs (8) that are also linked at their opposite ends to supports (10) equally adjustable in height along the struts (9), which makes it possible to regulate both the vertical rest position of the "U" bar (7) and the tension of the springs (8) to overcome in the exercises, depending on the the greater or lesser vertical distance at which its supports (10) are arranged with respect to said "U" bar (7).

Well then, in accordance with the essence of the invention, the relative arrangement in the horizontal plane of the supports (10) with respect to the vertical struts (9) is decisive when it comes to ensuring proper functioning of the accessories associated with the tower, as is the case of the "U" bar (7), so that if any of said supports (10) suffered a relative rotation with respect to its expected operating position, the distribution of forces through the springs (8) would become unbalanced, and could even cause muscle injuries to the user of the machine.

To avoid this problem, and in accordance with figures 2 and 3, it has been provided that both the section of the struts (9) and the inner section (11) of the supports (10) present a polygonal configuration, preferably octagonal and complementary that allows the vertical sliding of said supports along the uprights (9), as long as the grub screws (12) are released, preventing at all times the relative rotation in the horizontal plane of said supports (10) with respect to to the longitudinal axis of the struts (9).

This makes it possible to ensure a correct positioning of the supports (10) at all times, and consequently a correct functioning of the accessories associated with them, thus avoiding any malfunction that could cause an injury.

Finally, it only remains to point out that, although in the practical embodiment chosen, a pair of upper and lower springs (8) is associated with the "U" bar (7) by means of the corresponding supports (10), these elements elastics or springs (8) can participate in a greater or lesser number, to further increase the level of effort necessary to fold the "U" shaped bar (7), without affecting the essence of the invention.
