    DESCRIPTION
    Blade paddle.
    Field of the Invention
    The invention relates to a paddle paddle.
    State of the art
    Playing paddle tennis requires a shovel whose particular structure has a handle, an intermediate part and a head. The head does not include ropes, unlike tennis or other sports, but is composed of two impact surfaces perforated with holes and a central part composed of an elastic material such as foam, pierced by the holes.
    Known blades do not allow optimized performance in terms of impact power and head performance, due to the current construction of the blades.
    Description of the invention
    The invention aims to solve this disadvantage by proposing a new paddle blade whose power and performance are improved with respect to existing paddle blades.
    For this, the invention relates to a paddle blade comprising a perforated head with holes, an intermediate part and a handle, the intermediate part connecting the handle to the head, and the head including two impact surfaces and a central part formed from an elastic material that extends between the two impact surfaces. This blade is characterized in that it comprises an energy recovery element inserted between the two impact surfaces, which extends at least partially in the central part of the head, and capable of extending towards the intermediate part and on a part of the handle .
    Due to the invention, the energy recovery of the blade is improved, due to the presence of the energy recovery element, which allows the elastic material

    deformed during the impact of the ball returned to its initial position more quickly and, therefore, improves the energy efficiency of the head.
    According to advantageous but optional aspects of the invention, a paddle blade of this type can incorporate one or more of the following characteristics, which can be taken into consideration in any technically permissible combination:
    -The energy recovery element includes a sheet inserted in the central part, and two rigid parts positioned on both sides of this sheet, these parts extending in the intermediate part and in the handle.
    -The blade comprises a reinforcement structure that forms the perimeter of the head, whose two ends meet at the handle, and the rigid parts of the energy recovery element extend between the ends of the reinforcement structure.
    -The sheet is composed at least in part by a more rigid material than the elastic material that forms the central part of the head.
    -The two rigid parts are at least partly composed of a plastic material.
    -The energy recovery element is composed at least in part by a composite material.
    -The energy recovery element extends over the entire longitudinal dimension of the head.
    -The energy recovery element extends over the entire intermediate part.
    -The energy recovery element extends over the entire length of the handle.
    -The energy recovery element extends over the entire surface of the blade.
    -The handle has a length between 30 and 40% of the total length of
    the shovel.

    Detailed description of embodiments of the invention
    Figure 1 shows a paddle blade 2 comprising a head 4 perforated with holes 6, an intermediate part 8 and a handle 10. The intermediate part connects the head 4 to the handle 10. The handle 10 ends at a widened end portion 12 also called "handle cover". This last name is the one used in the rest of the description.
    The head 4 has a specific structure for the paddle. The head 4 includes two opposite and parallel impact surfaces S1 and S2 located on both sides of the middle plane P4 of the head 4. The head 4 comprises a central part 40 composed of a block of elastic material extending between the two surfaces of impact S1 and S2. An elastic material refers to a material that has the ability to deform under the impact of a ball, and to return to its initial form quickly. As an example,

    30
    35
    This central part 40 may be composed at least partially of a polymeric material, in the form of a foam block, such as EVA.
    The paddle blade 2 has a central longitudinal axis X which passes approximately through the central axis of the handle 10.
    The blade 2 comprises a reinforcement structure 14, whose rounded part 140 forms the perimeter of the head 4, and two rectilinear ends 142 that are joined in the handle 10. The central part 40 composed of an elastic material extends in the rounded part 140 of the reinforcement structure 14. As shown in the figures as an example, the reinforcing structure 14 may be tubular. Also, as an example, the reinforcing structure 14 may be composed of composite materials, for example, with a carbon fiber base, or any other rigid, but light material that does not deform, compared to the central part 40, under The impact of a ball.
    The blade 2 is also covered by a synthetic cover 18, shown in two halves 18a and 18b in Figure 2. This cover 18 is applied to both sides of the central part 40, at least in the head 4, and can extend up to above the intermediate part 8. The cover 18 may be composed of a composite material, for example, containing glass fibers or carbon fibers.
    The handle cover 12 has a hollow shape and fits into the end 142 of the reinforcement structure 14.
    In order to increase the power of the blade 2 and improve the energy recovery of the head 4, the blade 2 includes an energy recovery element 20 inserted between the two impact surfaces S1 and S2, and which extends by less partially in the central part 40 of the head 4, and capable of extending towards the intermediate part 8 and in a part of the handle 10.
    The energy recovery element 20 forms a rigid part that accumulates the energy of the ball during the impact and recovers it more quickly than the elastic material of the central part 40 by itself, making it possible to impart a greater velocity to the ball after leaving head 4.

    The energy recovery element 20 is composed at least in part of a material whose hardness and / or stiffness are greater than those of the elastic material from which the central part 40 of the head 4 is formed.
    As shown in Figure 2, the central part 40 is separated into two foam blocks 16A and 16B by the presence of the energy recovery element 20. More specifically, the energy recovery element 20 includes a sheet 200 located at the head 4 and separating the foam blocks 16A and 16B. The sheet 200 is parallel to the axis P4. Preferably, the sheet 200 is located at an equal distance from the two impact surfaces S1 and S2.
    The sheet 200 can be connected to a triangular core 202, which forms the inner part of the intermediate part 8. The core 202 is divided into two rigid parts 202A and 202B placed on both sides of the sheet 200. The two parts 202A and 202B are they extend parallel to the plane P4 and are extended by rectilinear parts 204A and 204B located in the handle 10. The rectilinear parts 204A and 204B extend between the ends 142 of the reinforcing structure 14, as shown in Figure 2.
    The rigid parts 202A and 202B are identical and are assembled against each other inversely with respect to the middle plane P4. In other words, once assembled according to Figure 4, parts 202A and 202B have symmetry with respect to the central axis X.
    Rigid parts 202A and 202B include housings 206 for receiving plate 200. Rigid parts 202A and 202B also include symmetrical assembly elements, such as rods 208 suitable for insertion into opposite holes 210. Rectangular parts 204A and 204B they also include assembly elements formed by deviated tabs 212 forming cavities 214. During assembly, the tabs 212 of the rectilinear part 204A are inserted into the cavities 214 of the rectilinear part 204B.
    Alternatively, parts 202A and 202B may comprise other types of assembly elements suitable for increasing stiffness and maintaining relative position relative to each other of parts 202A and 202B.

    The sheet 200 may be composed of composite materials, for example, with a base of carbon fibers, or glass fibers, or natural fibers, or any other structure more rigid than elastic foam, such as honeycomb structures, metal, etc. The dimensions of the sheet 200 (length along the X axis, width in the plane P4 and thickness perpendicular to the X axis) can be adjusted according to the desired power for the blade 2.
    The rigid parts 202A and 202B may be composed at least in part of a plastic material, for example, ABS.
    According to an advantageous aspect, the energy recovery element 20 can extend over the entire longitudinal dimension of the head 4. Therefore, the sheet 200 in this case is present to the longitudinal end of the head 4.
    As shown in the figures, the energy recovery elements 20 may extend over the entire intermediate part 8.
    Even more preferably, the energy recovery element 20 may extend over the entire length of the handle 10. Thus, in this case, the rectilinear portions 204A and 204B extend to the handle cover 12.
    If both the sheet 200 and the rigid parts 202A and 202B extend the entire length of the head 4 and the handle 10, the energy recovery element 20 extends over the entire longitudinal dimension of the blade 2, thereby providing a maximum energy recovery.
    According to an embodiment that is not shown, the energy recovery element 20 may extend in a single piece over the entire longitudinal dimension of the blade 2. In this case, for example, the energy recovery element 20 may be composed for a single piece of carbon.
    According to an embodiment that is not shown, the energy recovery element 20 can be extended in a single piece over all or part of the surface of the head 4.
    Alternatively, the energy recovery element 20 may be composed at least in part of metal or composite materials.
    According to an optional aspect of the invention, the handle 10 has a length L10 5 between 30 and 40% of the total length L2 of the blade 2. Thus, the handle 10 thus has a length greater than the length of the paddle blades that are currently marketed, which allows the player to modify his grip along the handle 10 or grab the shovel with two hands and thus impact on a wider variety of strokes by changing the shovel grip between two knock
    10
    In this case, the change in dimension of the handle 10 makes it possible to include a greater mass in the head 4, which makes it possible to obtain more inertia and a greater power.
    According to another optional aspect, the handle cover 12 has a larger extension on one side oriented along a direction parallel to the plane P4, as shown in Figures 6 and 7. In other words, a base, or end portion 120 of the handle cover 12, which forms the location with the largest transverse dimension of the handle cover 12, ie perpendicular to the X axis, has an asymmetric contour that moves more significantly away on one side of the handle cover 12 than on the other side 20. This major deviation extends along the plane P4, that is, parallel to the impact surfaces S1 and S2. This particular shape offers an additional wedge surface for the player's hand and allows him to present a safer grip when the impact occurs, and improves the power of certain strokes, particularly in shots.
