    [0004] Object of the invention
    [0005] The present invention refers to a system of selection of the weight to carry out exercises with weights in a gym machine, whose object is to provide a configuration that facilitates the selection of the weight to apply in each exercise, by means of the use of a fixed carriage. of the weights and a mobile cart in which the weights are automatically deposited to perform the exercise.
    [0006]
    [0007] It is another object of the invention to increase the safety of use of the weight selection system.
    [0008]
    [0009] A gym machine incorporating the system for selecting the weight is also an object of the invention.
    [0010]
    [0011] Technical problem to solve and background of the invention
    [0012] It is known to use machines to carry out exercises with weights that comprise a means of traction on which the user acts to carry out an exercise with weights, for which they allow modifying the weight with which each exercise is desired.
    [0013]
    [0014] The most widespread gym machines have a plurality of rectangular section weights placed one on top of the other, so that selecting with a pin inserted in the weight located in the lowest position, when performing the exercise, it is necessary to lift all the weights They are located above that weight where the pin has been inserted, so that with the action of a simple pin it is possible to select different workloads on the machine, which is done manually.
    [0015]
    [0016] In this sense, the Spanish invention patent can be cited with application number P201731126, in which a plurality of weights are also used, forming a stack, placed one on top of the other, but in this case the selection of the weight is carried out automatically by means of a actuator that moves a selection means that automatically establishes the weights with which the exercise must be performed.
    [0017] The invention provides a weight selection system for performing exercises and a gym machine with a new concept of selection, loading / unloading of the weights, which facilitates the selection and loading / unloading of the weight to be applied in each exercise, by using of a fixed trolley carrying the weights and a mobile trolley in which the weights are automatically deposited to carry out the exercise, in a way that facilitates the automation of its operation and the safety of use of the machine.
    [0018]
    [0019] Description of the Invention
    [0020] In order to achieve the objectives and solve the aforementioned problems, the invention provides a system for selecting the weight to perform exercises on a gym machine that comprises a plurality of weights, and which has the novelty of being characterized by the fact that it also comprises:
    [0021] - a fixed trolley from which the weights hang,
    [0022] - a retention mechanism for each of the weights hanging from the fixed carriage,
    [0023] - a mobile cart located under the fixed cart, which is configured to each house the hanging weights of the fixed cart, in housings, and to be pulled by a user to perform an exercise.
    [0024]
    [0025] By means of this configuration, the mobile carriage being coupled to the fixed carriage, with the weights located in the housings of the mobile carriage and retained hanging from the fixed carriage, when a retention mechanism is operated, the retaining weight is released, so that said weight is supported on the mobile cart instead of the fixed cart. In addition, when the retention mechanism works again, the weight is fixed again on the fixed trolley, with which this configuration allows the selection of the weight that the mobile trolley supports, which is the weight with which the user performs each exercise, so with the simple operation of the retention mechanisms of each weight, it is possible to select the weight that the mobile trolley supports, and therefore the weight with which each exercise must be carried out.
    [0026]
    [0027] In the preferred embodiment of the invention, each retention mechanism of each one of the weights, comprises a stem that is housed and retained in an emptying of each weight, by means of movable pivots, so that by governing the movement of the pivots it is materialized the release / fixing of each weight on the fixed carriage. Said movement of the pivots, for example, is materialized, by means of a linear actuator comprising a servo-motor that activates a pressure lug, which acts a button that produces the movement of the pivots.
    [0028] The invention has envisaged the incorporation of a driving mechanism of the mobile carriage, by means of a toothed belt that is attached to said mobile carriage to carry out its raising / lowering. In this way, the mobile trolley can be coupled to the fixed trolley to make the selection of the weights that the mobile trolley has to support, as described, and it also allows the user to assist when, while a user is performing an exercise, the system detects that the mobile car does not reach the end of the route, as will be discussed later.
    [0029]
    [0030] In addition, the system includes a mechanism for fixing the mobile trolley on the fixed trolley, to hold them together during the release / fixing of the weights on the fixed trolley, so that great security is provided when selecting the weight, by maintaining both cars linked together. In the preferred embodiment of the invention, said mechanism for fixing the mobile carriage on the fixed one is embodied by the drag mechanism itself, which keeps both carriages together during the operation of releasing / fixing the weights.
    [0031]
    [0032] In another embodiment of the invention, it is envisaged that the mechanism for fixing the mobile trolley to the fixed trolley is the same as the weight retention mechanism, but with the difference that the at least emptying is provided on the mobile trolley, in which also houses and retains a stem by means of movable pivots, which can be actuated by means of a linear actuator that operates a button that makes the pivots move. This mechanism can replace the drive mechanism to perform the function of fixing between carriages, or both can be used, for greater security of the system if required.
    [0033]
    [0034] Furthermore, the invention comprises a support movable on a guide, which is configured to mesh with the toothed belt and which is provided with a locking mechanism for its position on said toothed belt, so that when it is in the locked position it allows the user pull the mobile trolley, through the movable support to carry out an exercise and in the unlocked position allows the movable support to be moved on the toothed belt, to place it in an exercise start position (zero point), as discussed below . It is foreseen that the user can pull the movable support by any means, such as a bar, cable, rod, etc.
    [0035]
    [0036] In the preferred embodiment, the support comprises a toothed pulley and counterpoils by means of which it meshes with the toothed belt. In addition, pressure rollers by means of which the toothed belt is kept in permanent contact on the toothed pulley.
    [0037]
    [0038] Furthermore, the locking mechanism of the movable support comprises at least one locking bolt that is operable by a servo motor, through a cam, to block / release the rotation of the toothed pulley and thus allow the support to remain fixed or released in a toothed belt position.
    [0039]
    [0040] In the preferred embodiment, the locking mechanism includes two locking bolts, which are linked together by a lever, which is actuated by the cam when actuating the servo motor.
    [0041]
    [0042] To allow selection of an exercise start position (zero point), as noted above, it has been provided that the movable support comprises a mechanism for fixing an exercise start position which, in one embodiment, comprises a reel It is equipped with a claw and an axis, so that they are complemented by an alignment of hooves provided along the path of the movable support, so that once the exercise start position is selected, moving the movable support on the toothed belt, when turning the claw is housed in the hoof corresponding to the selected position, establishing the starting position of the exercise.
    [0043]
    [0044] In the preferred embodiment of the invention, the reel axis is fixed to an exercise bar, through which the mobile carriage is pulled, and whose rotation causes the claw to rotate to release it or insert it into a hoof. In this case, to perform the exercises, the user must act on the bar, but, as indicated, it could be any other element that allows pulling the mobile car.
    [0045]
    [0046] Furthermore, the system comprises a group of counterweights, in which a part of said group are fixed, by means of bands, to the sides of the support to counter the weight of the reel and bar. In addition, another part of the group of counterweights is attached to the toothed belt, to counter the weight of the mobile carriage. In other words, one end of the toothed belt is connected to the mobile carriage and the other to a part of the group of counterweights.
    [0047]
    [0048] The system is equipped with an electronic control module configured to govern the operation of the system automatically, so that the selection of the weights is carried out automatically, based on some exercise tables that it stores, and It is also configured to assist the user, through the traction mechanism, when it detects that when performing an exercise, the mobile trolley does not reach the end of the route established for said exercise in the table. This detection is carried out, for example, by using position sensors included in the electronic module. Furthermore, the electronic module allows directing the user during the exercises.
    [0049]
    [0050] Another important point is that the electronic control module is configured to establish, before each exercise, a lower point that must not be exceeded by the movable support.
    [0051]
    [0052] On the other hand, the invention relates to a machine that comprises at least one tower that is provided with the weight selection system defined above.
    [0053]
    [0054] In the preferred embodiment of the invention, the machine comprises two towers, which are connected by a bridge. Each of the towers comprises a weight selection system according to the description made.
    [0055]
    [0056] In this case, the ends of the exercise bar are fixed to the axis of the claw of the reels, to allow, by means of said bar, to perform the traction function of the mobile carts with the weights it carries, and to allow, by turning of the bar, make the fixation of the starting position of exercise.

    [0144] PREFERRED EMBODIMENT OF THE INVENTION
    [0145] Below is a description of the invention based on the aforementioned figures.
    [0146]
    [0147] The machine comprises a structure that is provided with two towers 1, joined by a bridge 2, although it could comprise a single tower 1 with the elements of the weight selection system of the invention that are described below. Each one of said towers 1 is configured to support a fixed carriage 3 from which a plurality of weights 4 hang, which are fixed, in said fixed carriage 3, by means of a retention mechanism 5, whose action produces the release of the corresponding weight 4 .
    [0148]
    [0149] Below the fixed carriage 3, a mobile carriage 6 has been provided, which is attachable to the lower part of said fixed carriage 3 and with the possibility of vertical movement on each guide 7, so that once the mobile carriage 6 is located under the fixed carriage 3, if a retention mechanism 5 is actuated, the weight 4 it retains is released, which comes off the fixed carriage 3 and is retained on the mobile carriage 6. By releasing a certain number of weights on the carriage mobile, the weight with which the user is going to perform the exercises is established, the value of which is the sum of the weight of the mobile cart plus that of each of the weights located on said mobile cart.
    [0150] The mobile carriage 6 comprises a housing 8 arranged in correspondence with each one of the weights hanging from the fixed carriage, so that when the mobile carriage 6 is coupled under the fixed 3, the weights 4 are also located in the corresponding housing 8, whereupon when a weight is released from the fixed carriage, its weight is supported on the mobile carriage, in the same position in which they were arranged on the fixed carriage. This structure also allows the weights to be hung again on the fixed carriage, depending on the different weight selections made during use, through the action of the retention mechanisms 5, as described below.
    [0151]
    [0152] Each of the weights 4 is provided with a recess 9 in which the retention mechanism 5 is located and retained, which is fixed on the fixed carriage 3, and which comprises a sensor 10 for detecting the actuation of the weight 4, which activates a linear actuator that comprises a servo motor 11 for actuating a pressure lug 12 that acts on a button 13 provided on a rod 14 for displacement of the two pivots 15 by means of which the anchoring of the retention mechanism inside the emptying 9 of the weight 4, so that when the actuation of a weight is detected, the servo motor is activated, which displaces the button 13 and causes the pivots 15 to retract, releasing the weight, which is located and retained in the housing 8 of mobile car 6, as discussed. To re-hang the weight from the fixed carriage, the mobile carriage is coupled to the lower part of the fixed carriage, position in which the stem 14 of the retention mechanism is located in the recess 9 of the weight 4, position in which the pivots 15 move in the expansion direction, whereby the weight is reattached to the retention mechanism 5, the weight being fixed to the fixed carriage 3 again.
    [0153]
    [0154] The movement of the mobile carriage to couple it to the fixed carriage is carried out by means of a drive mechanism 17 of a toothed belt 18, which engages a pinion 19, which is driven by a motor 20, one of the ends of the toothed belt 18 being fixed to said mobile carriage, so that when the toothed belt is displaced, the mobile carriage is raised / lowered, depending on the direction of rotation of the motor 20 of the drive mechanism 17. The other end of the toothed belt is fixed to a counterweight group 42, to offset the weight of the moving carriage and keep the toothed belt taut, as will be discussed later.
    [0155]
    [0156] To facilitate the loading / unloading operation of the weights on the mobile carriage 6, the carriages 3 and 6 are kept coupled, for which the motor 20 is activated, which moves the mobile carriage until it comes into contact with the fixed and the held together during the process of loading / unloading the weights.
    [0157] Optionally, it is envisaged that instead of or in combination with the driving mechanism 17, a fixing mechanism can be used between the carriages, which also uses retention mechanisms 5 of those described in the fixed carriage 3 to retain the weights, but with The difference is that, in this case, the retention mechanisms are arranged in correspondence with some locking cylinders 16, provided on the mobile carriage 6 and that are provided with a recess 9, so that, when the carriages are united, when acting the servo motor 11 releases the connection between the fixed carriage 3 and the mobile carriage 6 and vice versa. In the exemplary embodiment, four locking cylinders 16 with their corresponding retention mechanisms 5 are used, which are operated simultaneously to facilitate the loading / unloading operation of the weights.
    [0158]
    [0159] In addition, each tower 1 comprises a movable support 21, on a guide 48, and which meshes with the toothed belt 18, on which it can be fixed by means of a locking mechanism 25, for which the movable support 21, comprises a toothed pulley 34 by means of which it meshes with the toothed belt 18, one of whose ends, as mentioned, is fixed to the mobile carriage 6 and also the other end is fixed to the group of counterweights 42, to regulate the movement of said mobile carriage according to They will be described later and they maintain the tension of the timing belt. In order for the toothed belt to remain in permanent contact on the toothed pulley 34, respective counter-pulleys 35 and respective pressure rollers 36 are provided. The movement of the toothed belt is guided by pulleys 50.
    [0160]
    [0161] At least one of the sides of the toothed pulley 34, preferably both of them, are integral with a toothed wheel 37, in correspondence with each of which includes the locking mechanism 25 that comprises respective locking bolts 38, assisted by a spring (not shown), and that they are related to each other by means of a lever 39, which is operable by means of a cam 40 which is actuated by a servo motor 41, which when moving the cam 40 presses against the lever 39, which moves and, in Consequently it displaces the bolts 38, which are inserted between two of the teeth of each one of the toothed wheels 37, position in which the toothed pulley 34 is prevented from rotating, and consequently cannot move on the toothed belt, with what if in this situation the movement of the exercise bar 26 is carried out, it produces the dragging of the mobile trolley 6, by the force applied by the user. On the contrary, when the cam does not move the bolts 38, they are retracted by the action of the springs and do not brake the toothed crown 34, position in which the support 21 can move on the toothed belt 18. In addition, the locking mechanism It is equipped with a servo detector 49 of the path of the servo motors 11, to know the position in which the claws 23 are and to act in consequence, as described below.
    [0162]
    [0163] Furthermore, the movable support 21 is provided with a reel 22, which includes an axis 24 integral with a claw 23, so that said axis 24 is fixed to the end of an exercise bar 26, whose rotation produces the rotation of the claw 23, to position it at a height, zero point, from which the user will start the exercises, for which a vertical alignment of hooves 27 has been provided in the vertical path of the reel support, so that when the claw 23 is angularly displaced, it is housed in one of the hooves 27, establishing the fixation of the aforementioned zero position, and when it produces the opposite rotation of the exercise bar 26, it is released from the claw 23 to allow the exercise to be carried out, as will be described later .
    [0164]
    [0165] To regulate the rotation of the claw 23, it is provided that the reel 22 is provided with a slit hole 28 in which a pin 29 is housed, provided in the reel 22, to limit the rotation of the claw 23, between the position in the one that is housed in one of the hooves 27 or released. Furthermore, the support 21 comprises a sensor 31 that, by means of a magnet 32, detects the position of the claw 23 when it is retained in one of the hooves 27, safety position, and a ball positioner 30 to fix the safety position and the position of release of the claw 23 from the hoof 27, by means of recesses 33.
    [0166]
    [0167] Obviously, to produce the drag of the mobile carriage 6, described above, by means of the displacement of the exercise bar 26 by the force applied by the user, as long as the movable support is locked on the toothed belt; claw 23 needs to be in a position where it is not retained on any of hooves 27.
    [0168] The machine comprises at least one indicator light 45, signaling the operating state in which it is located.
    [0169]
    [0170] In addition, a part of the group of counterweights 42 is fixed to the sides of the support 21, by means of respective bands 43, guided by pulleys 44, to counter the weight of the system formed by the reel 22 and the bar 26. Another part of the group of the counterweights , as mentioned, they counteract the weight of the mobile carriage 6, as they are attached to one end of the toothed belt.
    [0171]
    [0172] In addition, the counterweights 42, level the weights so that the user does not have to drag the weight of the mechanical system, providing stabilization of the displacement of the exercise bar 26.
    [0173]
    [0174] For the operation of the system, a control module (not shown) has been provided configured to automatically control the entire operation of the machine, according to the description below.
    [0175]
    [0176] First of all, the user must be identified on the machine by any procedure, fingerprint, usb, password, etc., for which the incorporation of a recognition device (not shown) is foreseen on the movable support 21. In addition to the movable support 21, a touch screen 46 is included, through which different information is displayed to the user.
    [0177]
    [0178] Once the user is identified, the color of the indicator light 45 is changed, for example it changes from green to red, indicating that the machine is busy.
    [0179]
    [0180] Next, various information for the user is displayed on the touch screen 46 and allows him to select an exercise table, either manually or preset.
    [0181]
    [0182] By means of the motor 41, the lever 39 is stopped pressing through the cam 40, the bolts 38 retracting, which produces the release of the toothed pulley 34, allowing the support 21 to be displaced without the toothed belt 18 moving. Subsequently, the user must take hold of the bar 26 and by means of a twist of the wrist release the claw 23, position in which he can move the bar 26 together with the movable support 21 and the reels 22 in an upward or downward direction, to place it in the position desired in which the designated exercise is to be performed (zero position). With another twist of the wrist the user accommodates the claw 23 in any of the hooves 27, and through the screen 47, asks the user to confirm the position of the bar 26 for the start of the exercise. Which is confirmed by the user through the touch screen 46.
    [0183]
    [0184] The exercise table must then be loaded, either manually or automatically, showing on screen 47.
    [0185]
    [0186] Based on the loaded exercise table, the load of weights 4 to be carried out on the mobile cart 6 is selected, for which said mobile cart is coupled to the fixed cart, driving the motor 20 until they are coupled and holds them together, keeping taut the timing belt up (Figure 7), all while keeping the locking bolt 38 in the position where the timing belt 18 is released.
    [0187]
    [0188] Depending on the weight to be loaded, the servo motors 11 are activated, which actuate the pressure lugs 12, whereby the corresponding weights 4 of the actuated retention mechanisms 5 are released from the fixed carriage 3 and remain supported on the mobile carriage 6 .
    [0189] When the weights corresponding to the selected weight have been released, the mobile carriage 6 is released from the fixed carriage 3, and the motor 20 lowers the mobile carriage a certain distance, about 250mm. It is very important to be able to lower the mobile cart a reasonable distance, since this utility allows some security by providing a wide range of travel for the user, since by leaving the mobile cart separate from the fixed cart, the claw can be released from the hoof, since that when the mobile trolley comes into contact with the fixed trolley, this release cannot be carried out, so this function provides added security to avoid forcing the machine and security against misuse by a user.
    [0190]
    [0191] Subsequently, the locking of the movable support 21 on the toothed belt 18 at the zero point is activated by the motor 41 and the toothed pulley 34 is locked, so that the mobile carriage with the weights is attached to the support 21 and to the bar 26, position in which the user is indicated on the screen 47 that the exercise can begin.
    [0192]
    [0193] Through the screen 47 it guides the user on how to carry out the exercise, in form and in time.
    [0194]
    [0195] When the user finishes the series, he leaves the bar at the starting point of the exercise or at any other point, turning the wrist and placing the claw 23 on a hoof 27. To perform the weight change for the execution of a new exercise, the motor 20 is actuated, and by means of the toothed belt 18 it maintains the static mobile carriage 6 in the position of figure 6, and the motor 41 acts to unlock the toothed belt 18 of the toothed pulley 34, disconnecting the transmission between the mobile trolley and supports 21.
    [0196]
    [0197] Subsequently, the mobile carriage begins to rise by means of the motor 20, until it reaches the stop in the position of figure 7, keeping the mobile carriage attached to the fixed one. In this situation, the weights are loaded / unloaded, as already described.
    [0198]
    [0199] Once the weights are loaded, the motor 20 is actuated which lowers the mobile carriage to the working position and re-links the mobile carriage with the movable support 21, through the locking mechanism 25, as described.
    [0200]
    [0201] Through screen 47 it warns the user that they can continue with the exercise.
    [0202]
    [0203] When 80% of the exercise has been completed, the indicator light 45 changes to orange and when the exercises are finished, the machine returns to its initial position, and changes indicator light 45 to green indicating that it is free.
    [0204]
    [0205] As has been pointed out, the drag mechanism, together with the control module, also provide an effort assistance function, which is activated when the user is moving the bar 26 and there comes a time when he cannot reach the end of the journey. , which has been established for the exercise in the commented table, at which time the drive mechanism motor 20 is activated, to help the user to reach the end of the route established for the exercise. This assistance is configurable to adapt it to the conditions of each user, which provides the great advantage that the user will not need the assistance of another person to be able to do certain exercises. In addition, the control module detects the level at which the user has required assistance so that he can control the level of assistance required by the user in order to improve the performance of the exercise and bring the muscle to maximum growth. All this assistance functionality also provides a very important improvement.
    [0206]
    [0207] In the event that the claw 23 is not anchored to a hoof, no weight loading / unloading will be performed.
    [0208]
    [0209] At the moment the effort assistant works, the power supply to the machine is cut off so that the motor 20 of the drive mechanism 17 is blocked to prevent the bar from falling downwards.
    [0210]
    [0211] Finally, note that before each exercise, a lower point is automatically established that should not be exceeded by the bar 26, which also provides a very important safety point that protects the user against possible accidents.
