Description

DESCRIPTION

Foot clamping mechanism for exercise machines

TECHNIQUE SECTOR

The present invention refers to a foot support mechanism 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.

These types of machines allow you to carry out a wide variety of types of exercises.

The object of the invention is to provide a machine that includes a support bar for the feet with adjustment means both angular and along the machine, in order to allow the machine to be adapted to users of different sizes, as well as to allow greater number of exercises by virtue of the relative position of said foot holding mechanism, all in an extremely comfortable and simple way.

The invention is applicable both to physical exercise machines with a metallic structure/frame, as well as those made of wood or any other material.

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, frame that includes a support bar for feet or hands, as well as optionally a vertical column 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.

As for the bar to support the feet, this is usually angularly adjustable, to better adapt to the specific needs of each case.

In the utility model ES 1077615 U, an apparatus of this type is described, which presents the problem that when carrying out the change of angular position of the foot support bar, it is necessary to use both hands for said operation. , having to access a lower area of the mechanism, which involves not only an effort for the user himself, but also discomfort for him.

A similar situation occurs in the case of the machines described in the documents ES 2343574 T3 and ES 2278594 T3.

EXPLANATION OF THE INVENTION

The mechanism that is recommended, being of the type referred to in the previous section, presents a first characteristic of fundamental novelty consisting in that the means for regulating the position of the "U" bar supporting the feet, can be adjusted in such a way easy and simple dresser with one hand, additionally including means for its selective positional adjustment along the longitudinal frame that participates in said machine.

For this, the ends of said bar have an oblong slot in which the axis of rotation of said bar plays, said axis being associated with a spring that is fixed to said axis at one end, and at the other to the lateral arm of said bar. support for the feet, so that in order to achieve the blocking and corresponding angular fixing of the mentioned support bar for the feet, provision has been made for a lug to be included near the lower or free end of the arms of the bar. be housed selectively in a set of radial grooves provided for this purpose in an arched groove established in a piece that can be moved longitudinally on guides established on the sides of the chassis, duly stabilized by means of the corresponding grub screw, so that to unlock the position of said lug from the corresponding notch or slot, it is necessary to pull the bar against the tension of the spring that links it to the fixed axis, to locate di eight locking lug in the sector or arcuate groove from which the aforementioned locking grooves project radially, position in which said lug can be moved angularly, up to the desired position, so that once the user stops making tension against the spring, the lug will lock in the desired position, leaving said bar perfectly stabilized and locked.

In addition to being able to perform this operation with one hand, you do not need to bend down as much as with other existing systems, thus resulting in a simpler, more comfortable and faster manoeuvre.

However, to longitudinally regulate the position of the footbar with respect to the frame of the machine, it will be necessary to act on the corresponding grub screws established on the pieces that link the mechanism of the bar to the lateral guides of the chassis, which will be equipped with an alignment of holes in which to selectively link the aforementioned grub screws.

From this structure, an extremely versatile machine is achieved, easy to handle/adjust to the needs of each user, ideal for performing a large number of physical exercises with 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 side perspective view of a machine for physical exercise that includes a foot support mechanism made in accordance with the object of the present invention.

Figure 2.- Shows a profile view of the machine represented in the previous figure.

Figure 3.- Shows, finally, an enlarged detail of the machine at the media level angular and longitudinal adjustment for the footbar, in which the set screw has been removed so that the hole where it is housed can be seen.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the outlined figures, it can be seen how the mechanism of the invention is intended to be integrated into a machine for physical exercise in which a rectangular horizontal frame (1) participates, generally equipped with legs (2) at its ends, whose longitudinal beams include guides for horizontal movement of a carriage (3) against some springs, carriage (3) that includes supports (4) for shoulders, being able to count on one of its ends with a tower (13) with other accessories to perform other types of exercises, counting in opposition to said tower with a foot bar (6) with a "U" configuration.

Well then, in accordance with the invention, provision has been made for the foot bar (6) to be linked to a system for regulating the angular position of said bar, for which, on the sides of the chassis of the gymnastic apparatus, They have provided respective pieces (7) that can be moved longitudinally along guides (5) and provided with a hole (10) in which a grub screw (12) plays, which can be additionally and selectively locked in an alignment of holes (11) provided in the external guide (5), which allows the longitudinal position of the mechanism associated with the footbar (6) to be adjusted at will.

For its part, to regulate the foot bar (6) angularly, it has been provided that an arched groove (9) be established in the pieces (7) in which a series of radial grooves (9') are arranged in which a lug (8) can be selectively nailed in which the lateral arms of the foot bar (6) are finished off at their end, said arms having a torn hole (14) in which an axis (15) plays in solidarity with the pieces (7).

Thus, the lug (8) is designed to selectively lodge in one of the radial notches or grooves (9'), in a stable manner, and therefore establish the locking of the footbar (6) in a stable manner, or well be located in correspondence with the arched throat (9) and be able to carry out the change of angular position of said foot bar (6).

For this, the axis (15) that plays in the torn hole (14) includes an appendix (16) that is linked to the lateral arm of the footbar (6) by means of a spring (17) that maintains the locking position to the foot bar (6).

Consequently, to carry out the release of the foot bar (6) it is necessary to pull said bar backwards, against the spring tension, until the axis (15) comes to a stop with the lower end of the torn hole ( 14), position in which the lug (8) coincides with the arched groove (9) being able to move along it, and thus allowing the angular movement of the footbar (6), while when it stops doing pressure against the spring (17), the lug (8) will tend to its locked position, in the radial groove (9') in which it has been faced, thus immobilizing the mechanism, all with a maneuver that can be performed comfortably with one hand, from the central crossbar of the "U" of the footbar (6).
