Description

Gymnastic apparatus.

Object of the invention

The present invention relates to an apparatus gymnastic, specifically to an apparatus intended for lifting of weights, either directly or indirectly through cables and pulleys.

The object of the invention is to achieve, simultaneously to the classic flexion and extension movements of the arms, movements of pronation and supination of forearms

Background of the invention

In direct weightlifting they are used bars of adequate length, to whose ends discs are attachable of variable weight and number, so that at the ends of each balanced weights are placed that rise in the position of foot, lying down or in other positions.

Obviously and regardless of the exercise to be performed, the user's hands are pressed on a fixed and rectilinear element, said bar, so that the position of the arms, in the sense of pronation - supination, is fixed and is determined by the bar itself.

Gymnastic devices are also known in the that the weights are mounted on suspended cable supports that, driven by pulleys, they go to the location area body of the user, where they are finished off in a handle also materialized in a rigid bar, which retains essentially the problem of the previous case, that is the inability to perform exercises or pronation movements and supination while the movements of flexion and extension of the arms.

Description of the invention

The gymnastic apparatus proposed by the invention has been conceived and structured precisely in order to solve this  problematic, allowing to combine the bending movements and extension of the arms with the pronation and supination of the same as previously said.

To do this and more specifically said device, basically similar to a conventional weightlifting bar, with stops near their ends for location in the latter of respective weights or sets of weights, presents the particularity of that in a wide intermediate sector of the same forks in two parallel branches considerably spaced, between which they mount a pair of rings spaced apart from each other in correspondence with the user's hands, each of these being double rings, so that on an outer and fixed ring mount a core capable of rotating through a bearing freely endowed with a diametral arm that constitutes the handle of the apparatus so that this diametral arm can adopt an alignment arrangement with the ends of the bar, or any angulation regarding it to turn freely on the corresponding bearing, which allows cited pronation / supination movements while they are perform the classic bending and extension movements of the arms.

According to another feature of the invention each of the aforementioned rings is mounted on the two branches of the intermediate sector of the bar, through bushings longitudinally movable along said branches and endowed of blocking means thereon, so that said rings, and consequently the handles associated therewith are distancing adjustable at the user's discretion within wide margins

To get the blocking of those mentioned bushings with respect to the parallel branches of the bar can Use captive screws, with knobs, pins acting on bar holes or any other means that are Consider convenient.

Finally and according to another of the characteristics of the invention it is provided that in one of the cited parallel branches of the intermediate sector of the bar apparatus is established, specifically in its middle area a bushing with a ring, immobilized between side stops, ring intended for coupling the corresponding limb of the weight lifting cable, when they move vertically pulled by said cable and guided by pulleys, as in many gymnastic machines.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1. - Shows, according to a view in plant, a gymnastic apparatus made in accordance with the object of The present invention.

The 2nd figure. - Show the section in detail cross section of the same device, according to the cutting line A-B in Figure 1.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the gymnastic apparatus that the invention proposes this constituted from a bar (1), of similar length to that of a weightlifting bar, such as 1.36 meters, although obviously these dimensions can be variable, with the classic fixed rings (2) close to their ends, determinants of retention stops for weights, which in number and weight variable are intended to be coupled to the terminal sector (3) of each  one of the ends of the bar (1) and to be fixed by means of exterior retention of any conventional type, presenting said bar (1) the special feature that in a wide intermediate sector of the same, practically next to those mentioned stops (2), forks setting up two parallel branches (4-4 '), also parallel to the extreme sectors (3) of the bar and symmetrical with respect to the latter, branches (4) rounded ends (5) for an ergonomic connection to the bar ends (1).

In these parallel branches (4-4 ') two rings (6-6 ') are mounted, specifically with the collaboration of respective pairs of bushings (7) that, soldiers tangentially to the rings (6-6 ') are sliding along the branches (4-4 ') and fixed in any position selected for them with the collaboration of blocking elements (8), which in the figures are they materialize in pins (9) that selectively cross cross holes (10) operatively practiced along of the branches (4), but which can also materialize in simple captive screws or any other fixing means appropriate to allow the mobility of the bushings (7) for a variable distance between the rings (6-6 ').

Within each ring (6-6 '), through a bearing (11) a core (12) is established materialized in a second ring, capable of turning freely with respect to the surround and fixed ring (11), counting this nucleus (12) with a diametral heather (13) in function of device grip, dimensionally suitable for grip  It is easy and comfortable with the user's hands.

In this way the handles defined by the arms (13) can be aligned with the ends (3) of the bar (1) or form any angulation with said bar as shown in Figure 1, with constant relative mobility, which allows the user of the gymnastic apparatus that at the same time as performing the classic flexion / extension of the arms exercises, against the attached weights can perform exercises of pronation and supination of the forearms, by turning the cores (12) with respect to the rings (6-6 '), as shown by the arrows on the
Figure 1.

Finally and as a complement to the structure described, it is expected that at the midpoint of one of the branches (4) of the bar (1) another bushing (14) is established, fixed axially by a pair of stops (15) and to which a ring (16) for fixing for example with the collaboration of a carabiner, of the corresponding end of the drive cable of a group of suspended weights of said cable through pulleys, as it happens in certain gymnastic machines destined to perform arm exercises

Logically the length of parallel branches (4) of the bar (1) must be suitable for the handles defined by the arms (13) can be distanced from user will for example of the order of 90 centimeters, without that this dimension is not at all limiting, in the same way that this distance between branches (4-4 '), or what  the diametral dimension of the rings is the same (6-6 '), will preferably be of the order of 14 centimeters so that the handles (13) turn out dimensionally adequate.
