Description of an embodiment

The exercise machine of the present invention is known as "machine bench press" or "sith bench press". As can be seen in figure 1, this type of machine is characterized by having a horizontal bar, which is joined to two vertical drag through sliding reels. In this way, a user can lift and drop weights located at the ends of the bar in a "guided" manner by the vertical bars. The machine of the present invention has at least three embodiments that are shown in Figures 2, 3 and 4. Figure 5 shows the chassis 11 that can be applied to any of the embodiments of Figures 2 to 4.

Figure 2 shows the first embodiment of the machine of the present invention. The machine (1) has the horizontal bar (4), which at its ends joins the two reels (6, 7). In turn, each spool (6, 7) is attached to the toothed belts (3) in a fixed way. The toothed belts (3) are vertically arranged in an oblong shape such that the upper toothed pulley (5a) and the lower toothed pulley (5b) are located internally at the ends of each of the toothed belts. For the configuration shown in figure 2. the physical exercise machine (1) has two servomotors (2), each of which is connected with its corresponding upper toothed pulley (5a) by means of another transmission belt (2a). The servomotors (2) are connected by data link to a control device (3). The Lower toothed pulleys (5b) have free rotation. Alternatively, the servo motors (2) could be positioned in connection with the lower toothed pulleys (5b) in the same way as described for the upper toothed pulleys (5a). In this case, the upper toothed pulleys (5b) would have free rotation.

Figure 3 shows the second embodiment of the machine of the present invention. The machine (1) has the horizontal bar (4), which at its ends is attached to the two reels (6, 7), In turn, each reel (6, 7) is attached to the toothed belts (3) of fixed form. The toothed belts (3) are arranged vertically in an oblong shape such that the upper toothed pulley (5a) and the lower toothed pulley (5b) are located internally at the ends of each of the toothed belts. For the configuration shown in figure 3, the physical exercise machine (1) has a servomotor (2) connected by a transmission belt (2a) to the transmission pulley (5c) which in turn processes the resistance exerted by the servomotor (2) to the upper pulleys (5a) by means of the transmission bar (9). The servomotor (2) is connected by data link to the control device (3). The lower toothed pulleys (5b) have free rotation. Alternatively, the servomotor (2), the idler pulley transmission (5c) and transmission bar 9 could be placed in connection with the lower input pulleys (5b) in the same way as described for the upper toothed pulleys (5a). In this case, the upper toothed pulleys (5b) would have free rotation.

In figure 4 the third embodiment of the machine of the present invention is shown. The machine (1) has two horizontal semi-bars (4a), each of which has a free end that is located approximately in the geometric center of the physical exercise machine (1) and the other end of each semi-bar horizontal (4a) is attached to the two spools (6, 7). In turn, each spool (6, 7) is attached to the toothed belts (3) in a fixed way. The toothed belts (3) are vertically arranged in an oblong shape in such a way that the upper toothed pulley (5a) and the lower toothed pulley (5b) are located internally at the ends of each of the toothed belts (3). For the configuration shown in figure 4, the physical exercise machine (1) has two servomotors (2), each of which is connected with its corresponding upper toothed pulley (5a) by means of another transmission belt (2a). The servomotors (2) are connected by data link to the control device (8). This configuration allows the user to perform exercises where the resistance to vertical movement can be selected independently for each servomotor (2). The independent selection is made by the control device (8). The lower toothed pulleys (5b) have free rotation. Alternatively, the servomotors (2) could be placed in connection with the lower toothed pulleys (5b) in the same way as described for the upper toothed pulleys (5a). In this case, the upper toothed pulleys (5b) would have free rotation.

For all the above embodiments, the control device (8) controls the servomotor or ios servomotors (2) and more specifically the resistance to! displacement whether the user exerts an upward or downward vertical force. The user enters into the control device (8) the weight with which he wishes to perform the exercise and the control device (8) transforms that weight into mechanical resistance exerted by the servomotors. The user can select a resistance for the upward movement and another resistance for the downward movement. Additionally, the physical exercise machine (1) has the light indicator (10) that indicates the operating status of the physical exercise machine. For example, if the exercise machine (1) is available for use, the indicator light (10) is green. If the exercise machine 1 is busy, the indicator light (10) is red, and if the user reaches 80% of the programmed exercise, the indicator light (10) is orange. The bar (4) and the semi-bars (4a) are capable of rotational movement about their own axis of revolution. This rotated movement is detected by the reels (6, 7) that send the detected rotary movement to the control device (8), which will act on the servomotors according to the programming of the control device (8). In any case, the control device (8) can comprise a data display screen and a data processing apparatus that is programmable and allows the management and control of the operating modes of the machine object of the present invention in any of its possible realizations.

For all the previous embodiments, the physical exercise machine (1) can comprise a frame (11) as shown in figure 5 that supports at least the two upper toothed pulleys (5a) and two lower toothed pulleys (5b) and ai less one servo motor (2). Optionally, the frame can also support the control device (8) and comprise the work surface with guides (12), The work surface with guides (12) allows defining the geometric center of the machine (1) so that the user can be centered with respect to the machine (1) and thus perform an exercise correctly. Operationally, as seen in figure 8, the invention is designed to be able to be implemented without the need for hooks on the frame, since the machine is programmed to be able to stop in case it is detected that the user is not holding the bar and in case the user does not reach the previously programmed and specified values.

For any of the previous embodiments, figure 7 shows that at the ends of the bar (4) a device or sensor (13) can be arranged, where this sensor can be laser, artificial vision, pressure or conductivity , comprising an electronic module and at least one emitter (14) with an associated receiver (15), these being located at the ends of the bar and supported, for example, on the side spools (6, 7), and being in connection with the control device (8). The emitter (14) has the function of emitting a beam of light (16) that detects that the user is holding the bar (4) with his hands, in such a way that it allows the activation and deactivation of the operating modes of the machine object of the present invention. For all the previous embodiments, and as can be seen in figure 8, the bar (4) can comprise! minus one idler sleeve (17) with free longitudinal displacement along the bar. In figure 9 it is seen that this bushing is a hollow tubular element 5 that is superimposed on the bar and that is concentric with the bar (4) so that it can move longitudinally along it and allows the user to can exercise more muscles and therefore improve the performance of! system. As previously indicated, the bushing can be comprised in any of (the previously described embodiments, there may be at least one in a bar (4) as in the embodiments of Figures 2, 3, 4 and 6, and in the embodiment in which there is a split bar of Figure 5, one in each sero-bar (4a, 4b).

05-02: Safety functions: During the exercise the power supply to the machine is cut off, the bar would be blocked, to avoid accidents. Initially, a lower safety point is established, where the bar cannot go below said limit, to avoid accidents.

The invention also provides a computer program comprising about 5 code instructions adapted to perform a physical exercise method with the previously described machine, when said program is executed in the data processing apparatus of the machine control device.

This computer program, through the touch interface of the control device (8), the user identifies himself, selects his muscle group and selects the specific exercise of the muscle group, that is, he selects the exercise table, either manual or pre-established. To do this, a user code or any other type of user recognition can be manually inserted on the touch interface or display screen, and the group and exercise table or training systems can be manually selected.

Also, as previously mentioned, the bar (4) once it is grasped by the user can move freely. Due to the configured values and / or the detection systems such as the laser device, this bar does not fall under its own weight, while e! user is not exercising or the machine is not running. When the user is registered and is ready to perform the exercise indicated in the previous point, it is detected by the sensors that the user has grasped the bar (4) and a countdown begins that at the end of the established seconds releases the selected weight. At any time that the user separates his hands from the bar (4), the sensors detect it and the bar is weightless and the system is blocked for safety reasons.To this safety system, another is added that is defined by the route recorded during the exercise, so that the selected weight is only applied within the limits of the recorded route, it is left without weight if these limits are exceeded. In any case, the user grasps the bar (4), releasing the holding claws and / or being detected by the sensors, and moves the bar up or down with the pre-established help of the servomotor (2) to position the bar (4 ) in the desired position and do the designated exercise.

Entering the detail of! exercise, the program includes a strength test mode consisting of regulating the maximum continuous force that the user performs during a repetition in a specific exercise and muscle group. Once these values have been recorded, a force curve is made, an effort or power curve is calculated to apply in the rest of the workouts. This curve can be applied to a greater or lesser degree, for this a box is included in the interface and screen of the control device (8) in which the percentage of the curve with which to perform the training, asking to regulate and vary the force that is applied during the tour to adjust to the strength of each user, and being able to visually show the development of the exercise already carried out. Additionally, the control device may comprise a computer application to be able to retrieve and manage training sessions and to have remote control.

Taking into account these aspects, it can be defined that the method of operation of the machine comprises:

i. an initial state of rest (20) where the machine is at rest;

ii. a recognition of the user and start of the exercise (30) through a touch interface or display screen of! control device (8) and the release of the bar (4), either by a twist of the wrist that releases the bar from the safety claw or by the detection of the laser sensors;
