    [0002] Safety support system for sports training
    [0003]
    [0004] TECHNICAL FIELD OF THE INVENTION
    [0005]
    [0006] The present invention relates to a safety restraint system for sports training comprising a rail and a movable carriage in the lane, the system being configured to support a person hanging from the car by means of a rope, for example with the help of a harness
    [0007]
    [0008] The invention is applicable for sports training, as well as for sports or acrobatic practice, for sure, especially for sports whose essence is to slip (called “Sliz” sports), such as surfing, skiing, snowboarding, skateboarding, wakeboarding, etc. In these sports, the sliding movement implies the detachment of the surface on which the sliding occurs and return to it after an aerial phase. During this aerial phase, investments and rotations of the body are executed around the three axes of space as well as combinations thereof. These movements are usually performed on "rigid obstacles" and overcoming them requires a balance and high technical mastery. The impossibility of applying the slip control techniques of each modality means that the risk of falling is very high, causing serious trauma when falling on these obstacles.
    [0009]
    [0010] The safety restraint systems referred to in the present invention provide a secure restraint in the event of a fall, holding the injured person at a distance from the ground or obstacles, corresponding to the length of the restraint of the rope, thus avoiding accidents or fall incidents, which, on the other hand, complements and facilitates the possibilities of learning and training. These fastening systems are described in ES 2461632 A1.
    [0011]
    [0012] The present invention is also applicable in the field of motor rehabilitation to allow the zenith support of people. The use of devices, devices and systems that improve the results of sports training is one of the main fields of research in sports science. Such support devices for sports training generally have as main missions or develop the technique of athlete, providing proprioceptive and kinesthetic experiences that enhance the mechanical effectiveness of their movements, or influence their physical qualities such as the development of strength, flexibility, balance, coordination, etc.
    [0013]
    [0014] BACKGROUND OF THE INVENTION
    [0015]
    [0016] In the type of safety restraint systems mentioned above and described in document ES 2624632 A1, the rope is located through a sliding sheave system in the rail, fixing one of the ends of the rope to the person or sportsman, for example with the help of a harness. The other end of the rope is held by the coach or another person who accompanies the athlete during his trip allowing free motor practice and, if necessary, avoiding the blow on the obstacle when pulling the opposite end of the rope and thus holding the Sportsman by means of the rope. In particular, the coach can adjust the length of the rope between the lane and the athlete according to the elevation of the obstacle to be overcome by the athlete in his movement, maintaining a safe distance from the appropriate obstacle.
    [0017]
    [0018] In this sense, safety restraint systems are known that allow maintaining a safe distance from the appropriate obstacle regardless of the intervention of a trainer or operator, for example from WO2004033046A1. For this, the shape of the rail is modified, although the length of the clamping line does not suffer variations. Safety restraint systems are also known that offer an adjustment of the length of the rope without the need for the intervention of a trainer or operator and by external control, manually or motorized. These systems are normally used in the field of motor rehabilitation and to allow the zenith support of people. However, these safety restraint systems have the disadvantage of their complexity and cost.
    [0019]
    [0020] In view of the state of the known art, the present invention has the objective of providing a safety restraint system of the type described above that makes it possible to use it without the intervention of an operator that activates the safety system if it is necessary, that is to say being automatic, and that, on the other hand, is of simple construction. The invention aims to provide possibilities in the field of experimentation and the perception of vestibular sensations within a framework of absolute safety and that allows motor intervention as similar as possible allowing a transfer to the real situation of experiencing it.
    [0021] DESCRIPTION OF THE INVENTION
    [0022]
    [0023] This object of the invention is achieved by the security fastening system of claim 1. The dependent claims specify preferred embodiments of the safety restraint system according to the invention.
    [0024]
    [0025] The safety restraint system according to the invention comprises a reel rotatably fixed to the carriage and configured to fix the rope to the reel and to wind the rope on the reel by rotating the reel in a winding direction, a rack mechanism comprising a rack gear attached to the rail and a pinion gear attached to the spool and geared to the rack gear so that a displacement of the carriage when the rack mechanism is engaged produces a rotation of the spool in the winding direction, and locking means of the rotation of the reel that can be operated to block the rotation of the reel in the opposite direction to the winding direction.
    [0026]
    [0027] The incorporation of the safety device comprising the reel of winding the rope in which the athlete is suspended as well as the zipper mechanism, allows to adjust the length of the fastening line according to the height of the obstacle or ground clearance over the one that the athlete is going to slide in such a way that the safe distance is maintained on it, previously set so that the user does not get to contact his center of gravity with the obstacle or ground. On the other hand, the means of blocking the rotation of the reel prevent the rope from unrolling when the person pulls or hangs on it in the opposite direction to the winding direction.
    [0028]
    [0029] The replacement of the sheave or manual pulley of the safety clamping systems of the state of the art by this automatic device constitutes a simple constructive solution that allows to reduce the length of the clamping line automatically, being able to dispense with the intervention of a coach or operator outside the athlete or user of the system.
    [0030]
    [0031] The length of the clamping line can be adjusted in line with the characteristics of the obstacles on which it will slide while remaining at a safe distance from them, for example by adjusting the length of the rack gear section, the diameter of the gear of pinion or reel diameter.
    [0032] The rail may be supported by a frame or structure in a known manner, for example as described in ES 2624 632 A1, formed by polygonal frames of at least three sides. The car can slide on the rail using wheels in a known way.
    [0033]
    [0034] Advantageously, the system comprises means for releasing the rotatable reel to unlock the rotation of the reel in the opposite direction to the winding direction.
    [0035]
    [0036] The locking means and the releasing means may be constituted by an arm mechanism comprising a pivoting arm fixed to the car pivotally between a blocking position and a position for releasing the spinning of the reel by contact with a shoulder fixed to the rail through a contact wheel fixed to the pivoting arm rotatably. These release means allow the release and blocking of the reel rotation automatically, when the car travels in the lane as a result of the athlete's movement.
    [0037]
    [0038] Furthermore, the system advantageously comprises a plurality of rack and / or shoulder gears installed in the rail, which allows replicating the collection, blocking and / or release of the system along its entire travel path, controlling the length of the line of support of the athlete.
    [0039]

    [0054] PREFERRED EMBODIMENT OF THE INVENTION
    [0055]
    [0056] The present invention relates to a safety restraint system for sports training comprising the following technical characteristics in a preferred embodiment.
    [0057]
    [0058] The carriage 2 is movable by the rail 3 by means of wheels, two pairs of wheels in the example shown in the figures. A shaft 4 is fixed to carriage 2 in a rotating manner. The rope 5 or fastener line of the athlete is fixed to the axis 4, which constitutes the reel 4 to which the rope is wound 5. A pinion gear 1 or cogwheel is fixedly attached to the axis 4 at one end thereof.
    [0059]
    [0060] The pinion gear 1 acts, producing the winding of the rope 5, when it is related to a rack of rack gear 6 fixed at the bottom of the rail 3 of a length in accordance with the height of the obstacle on which the athlete is to slide , so as to maintain the safe distance over said obstacle.
    [0061]
    [0062] The pivoting arm 7 is fixed to the carriage 2 pivotally between a blocking position and a position for releasing the rotation of the axis 4, it is shaped like a "Z" and is provided with two contact wheels 8. The figures show the arm pivot 7 in the locked position of the rotation of the axis 4, thus preventing the rope 5 from unrolling when traction is exerted on the rope 5. The pivoting arm 7 releases and blocks the rotation of the axis 4 again when such wheels 8 interfere consecutively with a projection 9 conveniently installed on the side of the lane 3 opposite the side on which the rack gear 6 is installed. Thus, the release of the shaft 4 allows to return to the initial length of the clamping line or increase the length thereof. On the contrary, the gearing of the rack mechanism 1, 6, that is to say the gear between the pinion gear 1 and the rack gear 6, allows a shortening of the length of the clamping line, when the carriage 2 advances in the direction of travel
    [0063]
    [0064] The invention has been described according to a preferred embodiment thereof, but it will be apparent to the person skilled in the art that multiple variations can be introduced in said preferred embodiments without exceeding the object of the claimed invention.
