Definitions
- the invention consists of a device called trapezoidal front thrower or LFT.
- the launcher is composed of: two distinct rigid parts, for example in the form of a rod, serving as tension bars or sleeves to maintain the lateral rigidity of the device; a flexible portion of trapezoidal shape fixed along the entire length of each of its sides equal in length to one of the two rigid parts; this flexible portion serving as a zone for sending and receiving the object.
- Said rods also serving part of handles (one for each hand) may be at the level of the flexible part or outside; more precisely the invention provides a device consisting of a flexible portion, of trapezoidal shape such that the distance between lower ends of the flexible surface is shorter than the distance between the upper ends of said flexible surface, thus forming a trapezoid comprising two lateral sides equal in length and an upper side parallel to a lower side and of greater length to said lower side, of two distinct rigid parts, for example in the form of a rod, serving as tension bars, and for which the flexible part is fixed on its equal sides to each of the two rigid parts to maintain the lateral rigidity of the device; this flexible portion serving as an area for receiving and sending an object.
- the device is advantageously such that, the rigid parts form part of the handles, the shape of the flexible surface is adapted to stretch uniformly under the action of a fan opening movement by fan spacing of the hands of a user.
- the flexible portion is fixed over the entire length of its equal sides to each of the two rigid parts.
- said rods form part of the handles located in the zone. soft surface.
- the thrower is frontal because the grip is done with one hand on each sleeve, and the reception and sending are done in the human field of vision: the practice is immediate because natural unlike racquet games that are played laterally and with a single handle or handle.
- Existing inventions have a flexible surface of rectangular shape. The tension exerted on the flexible surface is due to the maximum spacing of the hands abruptly. This tension is exerted on the entire smooth surface in parallel horizontal lines.
- the spacing allowing the maximum tension over the entire flexible surface is a parallel movement.
- the natural human gesture of maximum hand separation is a fan-shaped movement, the upper arms sticking to the body like the needles of a clock that deviate from each other, and not a parallel movement .
- the natural gesture of spreading the hands in a fan on a rectangular flexible surface thus produces a maximum tension on the upper part (stretched and straight surface) and a very low tension on the lower part (loose and undulating surface).
- the result of the sending of a projectile is an uncontrollable result namely a trajectory backward or random and very low power.
- US 4,234,183 also provides a rectangular flexible portion which has the same disadvantages mentioned above.
- the invention consists of a device for manually sending and receiving an object, for example a ball in the context of a sports or leisure activity.
- This launcher is composed of two distinct rigid parts (for example in the form of a rod) and a flexible portion of trapezoidal shape, elastic or not, serving as a sending and receiving zone.
- Receiving the object is done by maintaining the handles sufficiently close together to form a hollow for damping the impact of the fall on the flexible surface.
- the sending of the object is done by abruptly spreading the hands to the maximum of the difference allowed by the width of the flexible surface, according to their natural movement of spacing ie fan. it is the tension created by the extension of this surface that allows the ejection of the object and its sending at great distances with only the hands as a driving force.
- the trapezoidal front launcher of the present invention overcomes this problem by the trapezoidal shape of its flexible surface 1 designed so that the distance between the lower ends of the flexible surface is shorter than the distance between the upper ends, the spacing movement then being fan-shaped, following the natural movement of the hands.
- the rigid portions 2 in the form of rods serving as tension bars follow the movement of the hands and tend the flexible surface 1 until the upper side 1a and the lower side 1b of the flexible surface, the upper side being of length above the lower side, be stretched.
- the device is advantageously such that the The shape of the flexible surface is adapted to stretch uniformly under the action of a fan opening movement.
- the tension is exerted maximally over the entire surface of the launcher of the present invention in horizontal lines parallel to the two bases (opposite sides of different lengths). The tension is then maximal on all the lines of the flexible surface the shock of the final separation of the hands occurring at the same time everywhere.
- the projectile is received by keeping the rigid portions sufficiently close together to form a recess for damping the impact of the fall of the projectile on the flexible surface.
- the sending of the projectile is done by abruptly spreading the hands to the maximum of the difference allowed by the width of the flexible surface in a fan-like movement of the hands and forearms: it is the tension created by the extension of this surface that allows projectile ejection at very great distances with only the hands as a driving force.
- Controlling the distance and height of the sending is done by modulating the power of the impact of the hand gap and the angle produced by the inclination of the launcher at the time of ejection of the object sent.
- the invention therefore consists of a device for manually sending and receiving an object, for example a ball, in the context of a sports or leisure activity.
- This launcher is composed of two distinct rigid parts and a flexible trapezoidal surface serving as sending and receiving area.
- Receiving the object is done by maintaining the handles sufficiently close together to form a hollow for damping the impact of the fall on the flexible surface.
- the sending of the object is done by abruptly spreading the hands to the maximum of the difference allowed by the width of the flexible surface, according to their natural movement of spacing ie fan, it is the tension created by the extension of this surface which allows the ejection of the object and its sending to very great distances with only the hands as motive force.
