Description

Portable Soccer Rebound or Deflection Training Device

field of invention

The utility model relates to a rebounding device for sports training.

Background technique

Many people have played this game by kicking a soccer ball against a brick wall, and then continuing to kick it after it bounces back (eg, repeatedly kicking against a brick wall so that it touches the wall once or twice). The game can be played alone or with multiple players, for example, taking turns kicking the ball. This game helps to exercise ball control skills and predict the running route of the ball.

However, such brick walls are not always found. Some walls have windows, some walls are near the road, and in some places there is no such wall (eg in the middle of the pitch).

Contents of the invention

One of the purposes of an embodiment of the present invention is to provide a sports training rebounding device that is portable and convenient to move and place anywhere.

The protection scope of the present invention is defined in the claims.

As mentioned above, this is a typical recreational and training device suitable for the ball sports (such as soccer) crowd (teenagers, teens and adults) who kick the ball against a surface such as a wall to bounce the ball for repeated practice. The present invention provides the opportunity for one to perform such training in a variety of settings using one or more wall-like surfaces. Some embodiments of the present invention are designed to be installed and removed from the flat pack so that the rebound box can be used anywhere. For example, walls are generally fixed, which is typically the case for restricting children's use of the wall area, such as in a garden. This results in grass being reused, excessive wear and silt zones in some areas of the grass. The mobility of this rebound box means it can be moved to different places, thus reducing excessive wear in certain areas. Another advantage is that one or more rebound boxes can be used during training, and one or more people can participate in the training. Rebound boxes are designed as follows: The box surface can be smooth or have several different shaped surfaces. This variety of shapes adds interest and challenge to the participant when considering the course of a ball bouncing off the rebound box or deflected by the surface of the rebound box. The mobility of the rebound box shows that it can be used, for example, on a football training field, which is not provided by a fixed wall. The present invention offers participants endless possibilities in using one or more rebound boxes for training or recreation. The use of the bounce box is not limited to soccer, but can be used for any activity that utilizes a surface to bounce or deflect a ball for fun. For example, it can be used as cricket training equipment.

According to one form, the present invention comprises a portable rebound or turn soccer training device comprising a rebound board including a plurality of projections through which a soccer ball can bounce off the rebound board or Deflection; characterized in that: the protruding part comprises separated protruding parts whose tips can make the surface of the football bend toward the inside of the football, and the distance between the tips of the protruding parts varies from 1 to 8 centimeters.

Detailed ways

Figure 1 shows a rebound box 101 into which a ball 102 is shot and bounces off the side of the box. This is one of the main functions of the rebound box.

A rebound box is provided in Fig. 2 . It has the shape of an elongated square-section hollow cavity with an elongated length of 100 to 200 cm and a height of 40 to 80 cm. She is made up of four metal (eg steel) plates 206, 208, 210, and 212, each substantially vertical. When mounting the resilient plate according to FIG. 2 , in this case the pair of screws or screws 214 tightly connects an edge region 216 of one sheet metal to an edge region 218 of an adjacent sheet metal. These screws or screws 214 may be automatically threaded into holes in area 218, or mounting areas (not shown) in area 218, or other securing means.

The rebound box 200 is first provided to the user in a flat tool box in disassembled form. These components include 4 identical metal plates 206, 208, 210, and 212, and screws or screws 214. It may be necessary to provide Description of listing 213 etc. to illustrate how to install the rebound box 200. These metal plates 206, 208, 210, and 212 are generally provided in registered layers, which may be strapped or bound, or housed together. These instructions may include specific instructions 215 giving details about training with the rebound box. Instructions 213 and 215 may be presented in written form (eg, the same or different brochures) or in a computer-readable form.

FIG. 2A shows the rebound box in a tool box 220 in the shipping state. The kit 220 can be easily shipped as a flat assembly and then assembled, for example in situ at the place where it is used. Furthermore, it can also be disassembled and transported or stored flat-packed.

In FIG. 2 , the rebound box 201 has holes on the side indicated by 202 , and these holes can be used as handles, so that the rebound box can be moved or picked up conveniently. In addition, the rebound box may have additional weight attached to the inside of the box, such as a bag filled with sand or a plastic container filled with water, through which to add additional balance or stability to the rebound box, so that the launched The ball will be bounced back. Toolbox 220 may include an empty container, such as a bag or the like, for sand or water or the like. Alternatively, the weight of the box itself is sufficient to allow effective use of the box (for example, if the box is made of a metal material (such as steel, etc.)).

In Figure 3, the rebound box 301 may be open ended, or have end pieces 302 at one or both ends of the rebound box, possibly to close the ends and/or provide additional stiffness.

In some embodiments, the panels (when mounted together/box installed) may rebound to the extent of a springboard, which increases the amount of rebound/deflection from the panels when a ball hits the middle of the panels. When struck by a ball, they bend and then straighten, increasing the momentum of the return ball.

In Figure 4, the 4 sides of the rebound box may have different outward (and inward) contact surfaces. Figure 4 gives some examples of the different outward facing contact surfaces a rebound box may have. A flat surface is indicated at 401 , a deformable surface (or corrugated surface) at 402 , an outer concave surface at 403 , a convex surface at 404 and a further deformable surface at 405 . The rebound box will support a myriad of surface shapes. If the rebound box has end faces, one or both of these end faces may also have differently shaped surfaces. A front plate may or may not be included in the kit 220 .

Although Figure 4 shows a version where the inner surfaces of the panels are flat, the inner surfaces of these panels can be plasticized to input springback/deflection characteristics. For example: one or more of the interior surfaces can be shaped, for any panel in Figure 4, or a "patching effect" to provide unexpected spring/rebound forces for both vertical and horizontal directions, or for vertical ribs to encourage vertical A change in the bounce angle on the panel. These panels are reversible (whether molded on both sides or not) so that they can be assembled as inside a box with each side of the panels facing outwards.

Figure 5 is a top view of the side surface of the rebound box. Concave surfaces are indicated by 501, convex surfaces by 502, flat surfaces by 503, and deformable surfaces by 504 and 505, respectively. The rebound box may support a myriad of surface shapes. Figures 4 and 5 show that the surface shape of the side of the rebound box changes in both end view and top view angles. When the rebound box has end faces, these end faces also have different shape surfaces both in terms of cross-sectional angles and perspective views.

Assembly of the rebound box is possible in various ways. For convenience, the rebound box can be easily packed or broken down into flat packs, so it can be easily stored and transported. Figure 6 gives an example on how to assemble these sides by means of the connection mechanism.

The first panel 602 has a tooth arrangement on a longitudinal edge 606 which interlocks in a crosswise fashion with the tooth arrangement at the end 610 of the other panel 312 in a mortise and tenon joint. The other ends of its panels 602 and 612 may likewise have tenon type connections, or may be connected to the other panels 614 and 616 by other means as shown (such as screws or hinges). Screws/bolts/other fastening devices may be used in tenon joints.

There is no limit to the size of the rebound box. The rebound box can have both sides in the shape of a rectangular box or one side in the shape of a square box or partly in the shape of a rectangle or partly in the shape of a box. The sides and other parts used in the rebound box are made of different materials. Rebound boxes may be constructed of metal, wood, or plastic, or a combination of certain types of materials. Typically, the materials employed should be weather-resistant (eg hard plastic) or those materials considered to have a weather-resistant finish (eg spray coating with weatherproof properties). Typically the rebound box should be between 50cm and 200cm in length and about 40cm to 100cm in height (possible range height = 30cm or 50cm to 150cm, either 50cm, 70cm, 90cm, 100cm, 110cm, 120cm, or 140cm; and length = 100cm or 90cm or 200cm or 125cm, or 150cm, or 175cm, etc. These dimensions can vary. A total weight of about 30kg might be a typical example (possibly between about 10kg and about 50kg, 20kg , 25kg, 30kg, 35kg are more typical ranges). In many embodiments, an ordinary person should be able to transport the box, and it should fit in the rear of a car (for example, a car with a folded down rear seat) .

Figure 7 gives an example of the design of the rebound box, wherein the sides of the rebound box can be fixed to a frame structure. The sides may be secured to the frame structure using screws or other types of fastening means such as clamps or bolts. The frame structure includes a peripheral box frame. It can be used as two rectangular/polygonal side frames and a certain number of connection structures (for example: 4 structures) to connect the peripheral side frames. This will help to flatten it. There is space inside the frame/box to hold things in place (eg: corner flags, training chest protectors, balls - something that might be used in soccer practice).

FIG. 8 specifically shows a cross-sectional view of the structure of the rebound box, wherein the sides of the rebound box 801 , 802 , 803 and 804 are fixed/supported on the frames 805 , 806 , 807 and 808 .

Frames 805, 806, 807, 808 each include an extended metal (eg steel, aluminum) face with deep channels 810, best seen in Figure 8A. The channel 810 has a parallel, truncated arrow-shaped cross-section, including a notch portion 812 and an inlet portion 814 .

Figure 8B shows a web 820 comprising a truncated arrow shaped cross-section with a protruding portion 822 which can be received in the notch 812 in use. In addition, the connecting piece 812 also has a raised surface portion 824, which can extend through the inlet portion 814 during use, and which adopts an internal threaded connection (refer to 826) to screw in a screw 828. The screw 828 connects the panels 801, 802, 803, 804 are tightly connected to the connecting piece 820 and then to the frame.

As shown in Figure 8A, frames 805, 806, 807, 808 may have profiled cross-sections throughout their length or at ends or at spaced locations along their length. Likewise, the entire edge portions of these panels may also have complementary interengagement cross-sections as shown in Figure 8B, or only in spaced areas along their lengths, in use in combination with complementary formations on the frame , for example, at the longitudinal ends of and/or between their end/edge portions. We also note that the protruding formations (eg: tab 820) have been caught in the profiled channel 810.

FIG. 9 gives yet another cross-sectional example regarding the construction of rebound boxes 901 , 902 , 903 and 904 fixed/attached to frames 905 , 906 , 907 and 908 .

Figure 10 illustrates in detail how to use two rebound boxes. The arrow pointing to the bounce box gives a path for a ball to shoot towards the bounce box. The arrow pointing away from the rebound box gives the path the ball will take to bounce off the rebound box. The ball can be shot to the rebound box by kicking the ball alone. The path a ball takes to bounce off the bounce box is affected by the surface of the bounce box the ball is shot at.

Example: The curved or irregular surface of the rebound box will cause the ball to bounce differently to the flat surface of the rebound box.

Figure 11 illustrates how to use three rebound boxes. Double arrows pointing toward the bounce boxes overlaid on a ball give the ball the path it will take as it hits each bounce box. In this example, a player 1101 shoots a ball (primarily a kick) into a rebound box (in sequence or possibly in any order). When the ball bounces, the player 1101 shoots the ball towards the same rebound box or one of the other rebound boxes.

Figure 12 further gives an example on how to use three rebound boxes. Double arrows pointing toward the bounce boxes overlaid on a ball give the ball the path it will take as it hits each bounce box. In this example, a player 1201 shoots a ball (primarily a kick) into a rebound box (in sequence or possibly in any order). When the ball bounces, the player 1201 shoots the ball towards the same rebound box or one of the other rebound boxes.

Figure 13 further gives an example on how to use three rebound boxes. Double arrows pointing toward the bounce boxes overlaid on a ball give the ball the path it will take as it hits each bounce box. In this example, players P1, P2, and P3 can choose to shoot the ball towards the rebound box, and they can also choose to shoot the ball towards player P4. Typically, the drill in Figure 13 can be done with 3 footballs in play.

Fig. 14 is a schematic diagram of the rebound box used when the players P1 and P2 shoot the ball to the rebound box and then shoot the ball to the goal after the ball bounces from the rebound box in the soccer field area. The single pointing arrow shows the path the ball traveled during this drill.

Fig. 15 is a schematic diagram of the rebound box used in training when the player P1 shoots the ball into the rebound box and then tries to shoot to a further rebound box in the area of the soccer field. In this example training with four rebound boxes, player P1 shoots the ball into the rebound box closest to the goal and then tries to shoot the ball towards the goal. These arrows indicate the main paths the ball might take in this drill.

Figure 16 shows how the rebound boxes can be fixed in position on top of each other or on top of each other so that one (or more) of them can be placed on top of each other thereby increasing the size and height of the rebound area. These arrows indicate the main paths the ball might take in this drill. Although two boxes are shown in Figure 6, one of the boxes can be stacked 2, 3 or 4 or more. Alternatively, they can also be positioned end-to-end to form a wall.

Figure 17 shows an example of the construction of the rebound box. The side panels of the rebound boxes 1705 and 1706 have holes at the corners of each side panel. The panels are then placed in fixed position to each other by screwing bolts into the corner areas 1701 , 1702 , 1703 and 1704 . The other two panels not shown in Figure 17 may be secured in place using the same corner area securing method. In addition, the same method can also be used to fix the end plate.

Figure 18 shows a corner region of the construction of the rebound box described in Figure 17. Side plates 2001 and 2002 are positioned by screwing bolts 2003 and 2004 into tenon nuts 2005 and 2006 . The tenon nut enters the position on the channel within the corner area 2007 .

Figure 19 shows the path that the ball travels when it is shot towards the rebound box 1901 and when it leaves one side of the rebound box. A specific example of the use of the present rebound box is if a person is practicing pitching on a cricket ball and the ball is headed towards the rebound box, the deflected ball is caught by a person practicing catch behind and beside the rebound box. As with the general design principles of the rebound box, the surface of the rebound box in this particular example may be flat, or one of several surfaces may change shape slightly (as the ball bounces off the surface of the rebound box). In this particular example, the rebound box is used upright at the end.

We can see that the ball or projectile can bounce or deflect from the direction it came out, but still keep going. "Recoil" does not only mean limiting the return of an object shot at the ball back to the player, but it generally means that.

Figure 20 is an example of the use of the rebound box 2003 in the context of cricket. Figure 20 is a top view of the cricket playing area. Players P1 , P2 , and P3 are located at the rear, on the sides of the cricket post 2001 . Player P4 hits the ball towards the post 2001 in front of the rebound box 2003. The rebound box 2003 is in the area where a batsman may attempt to attack a ball hit to the wicket 2001. The thrown ball can be bounced by the rebound box to the players P1, P2 and P3 who are practicing catching and defending the ball. The height and width of the rebound box can vary, but typically it should have the same height and width as the area where the batsman is likely to attack a thrown cricket. In this specific example, the function of the rebound box is that the pitcher can practice pitching in the direction of the side goal. In addition, the keeper can practice catching the ball (when a batsman hits a ball intentionally or unintentionally). The line segment with the arrow has given the path that the ball passes through when it is shot towards the rebound box 2003 and then bounced back.

In some embodiments, the weight of the rebound box itself is sufficient (ie without the use of internal ballast) if the panels and/or frame are made of metal.

Basketball is another sport for which portable rebound exercise equipment can be used.

In football, throw-in kicks can be practiced where a rebound box is used to bounce/deflect the ball towards another player.

Figure 21 gives an example on the construction of the rebound box, showing alternative/additional features. The side panels of the rebound boxes 2105 and 2106 have holes at each corner of the side panels and/or at one or more points along the length of the panels. The panels are then secured in a stable position to each other by using bolts inserted through holes in the panels and screwed into areas 2101 , 2102 , 2103 , 2104 and 2107 . For the two panels not shown in Figure 21, the same type of area fixing method (fixed on the pointer along the length of the panel) can also be used to fix them. Each block helps ensure that two adjacent panels are connected and displaced at the correct angle from each other. In addition, the same method can also be used to fix the end plate.

Figure 22 shows a plan view of the panel with 2206 indicating example locations. In this, holes can be made in the panel, through which holes the bolts can be inserted and screwed into the block.

Figure 23 shows a cross-sectional end view of three rebound boxes 2301, 2302 and 2303. Figure 23 shows how the snapback box can be swivel fixed on different panel sides so that different side panels can be placed on vertical and horizontal panels. The goal was to show how a single rebound box could support several different panel sides that would have different rebound and deflection effects on a ball shot to each panel side.

Figure 24 gives a cross-sectional view of three rebound boxes 2401, 2402 and 2403. Wherein, each rebound box includes three panels, and the panels of each rebound box are connected together through triangular connection blocks. Figure 24 shows how the snapback box can be swivel fixed on different panel sides so that different side panels can be placed on vertical panels. The goal was to show how a single rebound box could support several different panel sides that would have different rebound and deflection effects on a ball shot to each panel side.

Figure 25 lists some examples of the points of impact a ball may have (when the ball hits a 4-panel rebound box).

It can thus be seen that the panels 2501 referenced in Figure 25 have a number of points or protrusions 2502 that separate from the grooves 2503. In this example, the panels are made of sheet steel, but they could also be made of plastic or other suitable material. . Tips 2502 are spread out by equal distances 2504 between adjacent tips. Spacing 2504 is such that when ejected (hitting) the panel, a normal sized soccer ball contacts/touches one, or at most two tips (in this example). These tips act as strong grippers to poke into the goal, deflecting the surface of the ball. This can help the ball bounce off the "pointer" (protrusion) of the tip 2502 - facilitating the bounce/bounce characteristic of the control box.

We also noticed that if there are too many hands/tips 2502 in close proximity, the effect of using a flat springback becomes more and more pronounced.

In other embodiments, the tips 2502 can be spaced far apart so that the balls can only hit one at a time. In another embodiment, three tips can be hit simultaneously - but two of them are preferentially selected. This means that in some embodiments the spacing is about 3 cm, or 4 cm, or 5 cm, or 6 cm, or 7 cm, or 8 cm.

Also, note the arrangement shown in Figures 24 and 26 - with respect to the three saddlebags. It can be imagined as a triangular box. Furthermore, equilateral, isosceles, oblique, obtuse, or acute triangles are also conceivable - any type of triangle.

Of course, these panels are removable and replaceable.

The tip can be elongated into a raised or wavy bump. They can be detached from the tip/raised portion, no need to elongate the bump. For example, they may be the surface of a pineapple, or a regular pattern, preferably pointed convex, eg conical or pyramidal.

The tip may be formed at the apex of a V-shaped protrusion, usually with a flat side in the shape of a "V".

We note that the "tip" concept and the three-sided box concept can be associated with any other feature, or a combination of features described here.

Figure 26 shows some examples of the full center a ball might have (when the ball hits the 3-panel rebound box).

Figure 27 is a cross-sectional top view of three rebound boxes 2701, 2702 and 2703 standing vertically at the end. Figure 27 shows how the springback boxes stand upright at the ends so that different side panel surfaces can be placed on the vertical panels.

Fig. 28 is an angled top view of an example of a rebound box structure, in which panels 2801 and 2802 are connected by three connecting pieces 2803, and the edges of the panels are closely connected. The panels are supported by links 2804 secured between connectors 2805 . The connecting rod can be made of metal or ductile plastic, and is fixed on the connecting piece 2805 by a nut.

FIG. 29 is a cross-sectional view of the two-panel rebound box described in FIG. 28 , having two panels 2903 and 2904 . FIG. 29 shows how the link 2902 is secured by the connector 2905. Both ends of the connecting rod 2902 are bent at a 90 degree angle for insertion into the connector 2905 through the central bore. The design of the connector 2901 is the same as that of the connector 2905 . 2901 shows the central bore that is inserted into the end of the link 2902. The end of the link 2902 is threaded to allow a bolt to be threaded onto the end of the link thereby tightly securing the end of the link to the connector 2905 .

Figure 30 shows how the links in Figures 28 and 29 are connected to the connectors. The connecting rod before use is shown in 3001. Each end of the connecting rod is at a 90 degree angle to the connecting rod body and is generally threaded at the ends. When assembling the connecting rods, each end of the connecting rod 3004 is inserted into the central boreholes of the connectors 3007 and 3008, respectively. A nut 3009 may be threaded on the end of the link to secure the link 3004.

Figure 31 depicts an example of a rebound box structure. The two panels of the rebound boxes 3105 and 3106 have apertures at each corner of the panels or at one or more points along the length of the panels. The two panels are fastened to each other by inserting bolts through small holes in the panels and screwing into the panel blocks 3101, 3102, 3103, 3104 and 3107. The connecting rod 3105 is fixed between the connecting pieces 3101 and 3103 .

Figure 32 depicts an example of a rebound box structure. The two panels 3205 and 3206 of the rebound box have small holes at each corner of the panels or at one or more points along the length of the panels. The two panels are fastened to each other by inserting bolts through small holes in the panels and screwing into the panel blocks 3201 , 3202 , 3203 , 3204 and 3207 . 3208 is a connecting rod between the connecting pieces 3201 and 3203. Figure 32 also depicts how the feet are secured to the panels of the rebound box. The feet can be fixed to one or more panels. There can be one or more legs. The positioning and height of the feet may vary to alter the angle at which the rebound box stands, which affects how the ball bounces or deflects off the surface of the rebound box. The feet can be made of wood, metal, plastic or rubber. The feet can be secured to the panel with glue, bolts, nuts or clips.

FIG. 33 depicts cross-sectional end views of three examples of rebound boxes 3301 , 3302 and 3303 . Figure 33 shows how the rebound box can be rotated on different sides to provide different panels on vertical and horizontal or otherwise. This figure is intended to demonstrate how a single rebound box can support many panel sides that will have different rebound or deflection effects on the ball on each panel side.

FIG. 34 depicts an example of a rebound box structure in which a rebound plate 3401 is supported by two side plates 3402 and 3403 and a cross plate 3404 between the side plates 3402 and 3403 . All panels may be joined together by joining the panel pieces or using nuts and bolts 3404.

The front plate (rebound plate) 3401 has a chevron corrugated surface forming a protrusion 3405 with a point 3406 . The distance between the tips is approximately 4 mm, ensuring that when a typical full size soccer ball hits the panel at least once (and generally no more than twice), the tips will poke into the ball and turn the ball towards the Bounce away from the panel, causing the ball to bounce back. Compared to a partially rounded surface such as a dome or cylinder, the tip 3406 is pointed and sharp and thus long and pointed in nature like a spike.

The side panels 3402 and 3405 are identical and each have an upper flange 3407 and a lower flange 3408 . The side panels, like the front panels, are made of steel. Flanges 3407 and 3408 are threadedly connected with upper and lower flanges 3409 and 3410 on the front plate through bolts 3404 .

Flanges 3407 and 3408 have through holes 3411 for removably inserting rubber/plastic/elastic material feet 3412 shown in lower flange 3408 in the figure, and upper flange 3407 also has through holes 3411. When the device is reversed (see discussion of FIG. 35 below), the legs 3412 can be removed from the flange 3408 and installed on the other flange 3407 so that they can still function as legs. This process requires no tools. Two sets of feet may also be provided, with one set being redundant at any given location on the device. It is also possible to provide no feet, and in this case the through hole 3411 can be used to tie the rebound box to a pile (for example, when the rebound box is used on a lawn).

The flange can be used as a carrying handle to ensure that people can lift and carry or at least slide and move the unit.

A strut 3413 is movably mounted between the side plates.

The unit can be removed and the sides and front panels (or struts) of the unit can be laid flat, eg in a box for original retail or shipping, or in the back seat of a car.

The side panels 3402 and 3403 are trapezoidal, so that when the device is turned upside down, the rebound panel 3401 can still be displayed from different angles on the ground (see the discussion of FIG. 35 below).

Figure 35 depicts an example of the structure of the rebound device, wherein the rebound device shown in Figure 34 has been turned over 180 degrees. After flipping the rebounding device, the angle of the rebounding plate 3501 can be presented at different angles, compared to the rebounding from the panel surface shown in FIG. Panel 3501 is secured by side panels 3502 and 3503 and a cross panel between side panels 3502 and 3503 . All panels can be joined together by joining individual panel pieces or using nuts and bolts.

Figure 36 depicts an example of a rebound box structure where rebound panels 3601 and 3602 are secured by two side panels. Figure 36 is a cross-sectional side view showing the sides 3603 of the two side panels. This structural example allows the use of two rebounding panels at the same time. The side panels can be installed with different angled sides, allowing the snapback panels to be secured from different angles.

Figure 37 depicts an example of a rebound box structure in which the rebound plate includes a plurality of struts. The two side plates 3703 and 3704 are supported by a plurality of links 3701 and 3702 fixed between the two side plates 3703 and 3704 . In this example of the rebound box structure, the struts serve as the front and rear rebound plates of the rebound box. This construction example allows the use of both the front and rear rebound plates of the rebound box. The struts can be made of metal, wood or plastic material, or any material of sufficient strength.

Figure 38 depicts a cross-sectional view of an example of a rebound box structure in which the side panels of the rebound box are mounted with a plurality of struts secured between the side/end panels. Side/end plate 3801 shows an example of how the struts are secured to the side/end plate. The struts are secured to the side/end plates by screwing the bolts/screws into the threaded channels at the ends of the struts. This structural example allows the use of both side panels of the rebound box at the same time. In this example, the struts are mounted linearly on one side of the rebound box and non-linearly on the other side of the rebound box.

39 is a cross-sectional view of a snapshot moment when a ball 3901 hits a rebounding plate, wherein the rebounding plate 3902 includes a plurality of ridges. The board surface is bounced off. This ridge concentrates spring force on the ball, causing the ball to bounce back faster. The spacing between the ridges is important, if the distance between the tips of the ridges is too far, the ball will be squeezed between two adjacent ridges (and will not bounce back since there is no punching action), obviously, if the ridges If the distance between the ridge tips is too close, there is not much difference from a plane. For a 5# soccer ball, the distance between the tips of the ridges should be 4 cm. The spacing between the tips of the ridges can vary from 1 to 8 cm.

Fig. 40 is a cross-sectional view of a snapshot moment when a ball 4001 hits a rebound board, wherein the rebound board 4002 includes a plurality of struts, and the struts of the rebound board can be used as pointers in the ball to make the ball rebound from The board surface is bounced off. This strut concentrates the spring force on the ball, causing the ball to bounce back faster. The spacing between the struts is important, if the distance between the struts is too far, the ball will be squeezed between two adjacent struts (and will not bounce back because there is no punching action), obviously, if the wrinkle ridge If the distance between them is too close, there is not much difference with a plane. For a 5# soccer ball, the distance between the tips of the ridges should be 4 cm. The spacing between the tips of the ridges can vary from 1 to 8 cm.

Figure 41 shows a rebound box where rebound panels 4101 and 4104 are secured by two side panels. Figure 41 is a cross-sectional side view showing the side 4101 of the two sides. In this embodiment, a "pointer" or protrusion 4103 is inserted into the steel section of the side plate. The pointer 4103 is a positioning and supporting structure of a spring 4201 (as shown in FIG. 42 ). The spring 4201 can increase the rebound force exerted by the rebound plate on the football. Spring 4201 is generally installed in the middle of panels 4101 and 4104. The compression spring shown in FIG. 42 is generally installed above the pointer 4103 before the rebound plates 4101 and 4104 are assembled on the side plate 4101. The rebound plate and side plates are joined together by releasable connections, such as nuts and bolts shown in reference number 4102.

Figure 43 is a cross-sectional side view of an example structure of a resilient plate 4301 in which the height of the ridge 4302 is higher than that of the other ridges of the resilient plate. Specifically, the ridge height of the ridges 4302 is generally 0.2 to 4 cm higher than the other ridges of the resilient board, and the distance between the tips of the ridges can vary from 1 to 8 cm. There are other rebounder panel designs in which there are multiple ridges that are higher in height than the other corrugated ridges of the rebounder panel. The height of the ridges will vary, but the height of the other ridges of the rebound board generally varies from 0.2 to 4 cm. In Figure 43, crimp ridge 4203 has a ridge height of 3.5 cm (measurement limits shown as 4304), while the other crimp ridges have a ridge height of 3 cm. In Figure 43, the distance between adjacent ridge points is 4 cm (the measurement limit is shown as 4305). The distance between ridge points will vary, but the distance between adjacent ridge points generally varies from 1 to 8 cm. The dotted line 4303 shows that the ridge 4302 is taller than the other ridges in this resilient panel design.

For example, ridges 4302 have a ridge height of 0.2 cm, 0.5 cm, 0.8 cm, 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm, 3.5 cm, or 4 cm higher than other ridges.

FIG. 44 shows the effect of a ball 4402 bouncing off a rebound plate 4403, wherein the rebound plate design is the same as that shown in FIG. 43 . In this example, the impact location of the ball on rebound plate 4403 causes the higher ones of ridges 4401 to have an upward rebounding effect on the ball as shown at 4404 . The impact location of the ball is such that the ridges 4401 do not make direct contact with the ball (or the ridges 4401 have different points of contact with the ball), i.e. the ball will bounce back differently as the ball hits different locations on the rebound plate , that is, the ball will be bounced at different speeds and/or in different directions.

FIG. 45 shows the effect of a ball 4502 bouncing off a rebound plate 4503, wherein the rebound plate design is the same as that shown in FIG. 43 . In this example, the impact location of the ball on rebound plate 4503 causes the higher ones of ridges 4501 to have a downward rebounding effect on the ball as shown at 4504 . The location of the impact of the ball is such that the ridges 4501 do not make direct contact with the ball (or the ridges 4501 have different points of contact with the ball), i.e. the ball will bounce back differently as the ball hits different locations on the rebounding plate , that is, the ball will be bounced at different speeds and/or in different directions.

In many embodiments, the sheet material (eg, steel sheet) of the resilient plate has relatively sharp protruding portions (eg, ridges/points) extending in the same direction. The spacing between the protrusions should ensure that a 4# or 5# ordinary soccer ball can hit at least one protrusion, but no more than two protrusions at a time, or no more than three protrusions at the most (for some embodiments ). This maintains the high strength with which the projection "pokes" into the football.

The protrusion is sharp compared to a domed, hemispherical or semicircular protrusion.
