Description

A football training frame and a human wall ball net

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 23, 2024, with application number 202420170204.9 and invention name “Training Frame”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of sports equipment, and in particular to a multifunctional small-scale human wall training frame for footballs used for quick placement of free kicks and a special human wall ball net. Background Art

[0003] Most free-kick simulation wall devices currently available on the market are complex, heavy, and expensive to purchase, or large, making them difficult to store and transport. They are typically only available to professional clubs and teams at specific training venues. This makes set-piece practice difficult for average football enthusiasts, dampens their enthusiasm for learning the skill, and reduces their practice efficiency.

[0004] Free kick training is a crucial aspect of soccer practice, often requiring the use of simulated objects to act as a human wall for defensive players in order to enhance the effectiveness of free kick practice. However, traditional simulated human walls or general-purpose nets often suffer from the aforementioned issues, further hindering participation and effectiveness of practice for average soccer enthusiasts. Summary of the Invention

[0005] In response to the deficiencies in the existing technology, the technical problem to be solved by this application is to provide a training rack that increases the convenience of user training, aiming to solve the technical problems of the existing football wall rack, which is complex in structure, too large in size, time-consuming to place, easy to damage, and inconvenient to store and use.

[0006] In order to solve the above technical problems, the present application is implemented through the following solution: a football training stand and a dedicated ball net thereof, comprising: a top beam, a first connecting part, a ball net and a supporting structure, the top beam being connected to the first connecting part, the supporting structure being connected to the first connecting part, and being used to support the top beam at a fixed height from the ground when in use, the ball net comprising multiple edges, one of which is connected to the top beam, and the remaining edges being free movable edges and not connected to the top beam and the first connecting part.

[0007] Furthermore, the width X of the training rack is designed according to the following formula: A is the ball release angle and is 12.7° to 16.7°, n is the number of times the training rack is moved forward in units of frame width and is a positive integer, H is the height of the training rack, and H0 is the reserved height for passing the ball.

[0008] Furthermore, the height H of the training rack is designed according to the following formula: A is the ball-exit angle and is 12.7° to 16.7°, n is the number of times the training rack is moved forward in units of frame height and is a positive integer, and H0 is the reserved height for passing the ball.

[0009] Furthermore, the support structure includes a support part and a lower frame, the support part is connected to the first connecting part, the lower frame includes a ground-contact bottom beam part and a second connecting part connected to the ground-contact bottom beam part, and the second connecting part is detachably connected to the first connecting part; wherein, the bottom surface of the support part and the bottom surface of the ground-contact bottom beam part are on the same horizontal plane, and the top beam part, the first connecting part and the lower frame enclose a ball-passing space.

[0010] Furthermore, the extension direction of the support portion forms a first angle with the extension direction of the first connection portion, and the first angle is 80-100 degrees. The extension direction of the second connection portion forms a second angle with the extension direction of the ground-attached base beam portion, and the second angle is 80-100 degrees.

[0011] Furthermore, the support portion, the first connecting portion and the top beam portion are integrally formed in sequence, the support portion and the first connecting portion are connected by a circular arc transition, the ground-contacting bottom beam portion and the second connecting portion are integrally formed, and the ground-contacting bottom beam portion and the second connecting portion are connected by a circular arc transition.

[0012] Furthermore, the support portion, the first connecting portion and the top beam portion are segmented structures, and / or the lower frame is segmented structure.

[0013] The human wall ball net includes a training frame, wherein the top beam of the training frame is provided with vertical ropes, the vertical ropes are strip-shaped rope segments, and the vertical ropes are arranged in a horizontally dispersed manner. On the training frame, the vertical ropes are not connected to other parts of the training frame except the top beam of the training frame.

[0014] Furthermore, a transverse connecting rope is provided for connecting the vertical rope. The upper end of the vertical rope is provided as a vertical rope loop, which can surround the top beam of the training frame and be tied thereto.

[0015] Furthermore, the vertical rope loops are connected with a transverse connecting rope, which connects the vertical rope loops in series and passes through the top beam of the training frame. Other vertical rope parts below the vertical rope loops are in a completely suspended free state.

[0016] Furthermore, the horizontal connecting rope can be connected in series with the vertical ropes located below the top beam.

[0017] Compared with the prior art, the beneficial effects of the present application are as follows: a football training frame of the present application comprises an upper frame, a lower frame and a ball net, wherein the upper frame comprises a top beam portion, a first connecting portion and a supporting portion, and the lower frame comprises a ground-contact bottom beam portion and a second connecting portion. When the first connecting portion is connected to the second connecting portion, the upper frame and the lower frame enclose a ball-passing space, which has a simple, novel, firm and durable structure; and one edge of the ball net is connected to the top beam portion, and the other edges are free movable edges, so that the ball can easily slide through the net, which is better than " When the rack is surrounded by a net, the four sides of the net and the area inside the net are subjected to stress due to the strong impact and pulling of the football. By connecting only one edge of the net to the top beam, the net can be protected from stress to the greatest extent, thereby reducing damage and allowing the football to pass through. The football training rack of the present application, with its numerical design of the width / or height of the outer frame and the method of placing the training rack at a distance that is an integer multiple of the width / or height, also creatively enables the training rack to function as a "folding ruler" and "protractor", and can quickly indicate the ball outlet with strict requirements. Angle, and the time required to measure the distance when the training frame is initially placed or when it is re-placed after being knocked down can be minimized; the smallest size of the training frame can be within 1m high and 1m wide. The area of ​​a frame and the net can replace the obstacle angle that was previously formed by 4 or 5 large human walls (a total of about 2m high and more than 2m wide) lined up in a row, greatly reducing the size and cost of the human wall, and making it easy to store and carry. It can even be stored at home or in a car for use; the flexible net can also avoid the use of rigid solid human walls in the past. Repeated direct impacts from soccer balls can cause various parts of the net to become susceptible to damage and wear. However, the cost of repairing or replacing the net is significantly lower than patching or replacing existing human walls. The training frame is lighter than previous large human walls and can be lifted off the ground with a single arm for easy movement around the field, quickly relocating to any location. Its stylish, rounded shape prevents scratches from accidental collisions, offering exceptional safety. This training frame requires no air pump for inflation, saving time and convenience, while also avoiding the risk of damage to inflatable human walls during storage, transportation, or when struck by soccer balls.

[0018] The special human wall net in this application eliminates the horizontal ropes and is composed only of vertical ropes, which reduces the force and the range of traction when the football hits the net, allowing the football to pass through the net more easily and reducing the impact on the net body. The vertical ropes are connected to the horizontal connecting ropes through a fixing device at the top to ensure that the distance between each vertical rope is no greater than the diameter of the football, thereby preventing the football from leaking out of the net gap and improving the training effect. When the football touches the vertical ropes, the vertical ropes will shake, which can provide instant visual feedback to the players, helping the players to adjust their hitting techniques in time and avoid repeating mistakes. The net has a simple structure and low maintenance cost. If the vertical ropes are damaged, only individual vertical ropes need to be replaced, avoiding the high cost of replacing the entire net.

[0027] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0028] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal connections between two components; they can refer to wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0030] As shown in Figure 1, the present application provides a football training stand, comprising: an upper frame 100 and a lower frame 200, the upper frame comprising a support portion 110, a first connecting portion 120 connected to the support portion 110, and a top beam portion 130 connected to the first connecting portion 120; the lower frame 200 comprises a ground-contact bottom beam portion 210 and a second connecting portion 220 connected to the ground-contact bottom beam portion 210, the second connecting portion 220 being detachably connected to the first connecting portion 120; the ball net comprises a plurality of edges, and one of the edges is connected to the top beam portion 130; wherein the bottom surface of the support portion 110 and the bottom surface of the ground-contact bottom beam portion 210 are on the same horizontal plane, the upper frame 100 and the lower frame 200 enclose a ball passing space 400, and the ball net is at least partially located in the ball passing space 400.

[0031] In one embodiment, as shown in Figure 1, the support portion 110, first connecting portion 120, and top beam portion 130 are integrally formed, with the support portion 110 and first connecting portion 120 connected by a circular arc transition. The ground-engaging bottom beam portion 210 and second connecting portion 220 are integrally formed, with the ground-engaging bottom beam portion 210 and second connecting portion 220 connected by a circular arc transition. This sleek and novel profile prevents injury to trainees from accidentally touching the training rack.

[0032] In other embodiments, as shown in Figure 2, the upper frame 100 can be a segmented structure, and / or the lower frame 200 is a segmented structure, that is, the upper frame 100 can be made into a multi-segment combination, the lower frame 200 can be made into a multi-segment combination, and both the upper frame 100 and the lower frame 200 can be made into a multi-segment combination. The specific combination form is not limited. For example, the bold lines in Figure 2 are segmented interface positions, and each segment can be detachably connected by screws and other fixings. This combined structural setting facilitates the storage, transportation, and carrying of the training frame to meet the needs of different uses.

[0033] It can be understood that since the bottom surface of the support portion 110 and the bottom surface of the ground-contacting bottom beam portion 210 are at the same horizontal plane, and the support portion 110 has a supporting function, the support portion 110 and the ground-contacting bottom beam portion 210 can be placed on the ground when in use.

[0034] It should be noted that one edge of the net is connected to the top beam 130, and the other edges are free movable edges, that is, only one end of the net is tied to the top beam 130, and the other edges are not bound to the training rack. Compared with "tying the net on all sides of the rack", it can minimize the force on the four sides of the net or the area inside the net caused by repeated strong pulling or impact by the football, thereby reducing damage. After touching the net, the ball usually just "slides" over the net and continues to fly forward.

[0035] In one embodiment, the extension direction of the support portion 110 forms a first angle with the extension direction of the first connecting portion 120, and the first angle is 80-100 degrees. Preferably, the extension direction of the support portion 110 forms a 90-degree angle with the extension direction of the first connecting portion 120. When the training frame is placed on the ground, it can stand upright perpendicular to the ground, thereby improving the ball blocking effect.

[0036] In another embodiment, the extension direction of the second connecting portion 220 forms a second angle with the extension direction of the ground-contacting bottom beam portion 210, and the second angle is 80-100 degrees. Preferably, the extension direction of the second connecting portion 220 forms a 90-degree angle with the extension direction of the ground-contacting bottom beam portion 210, so that the ball passing space 400 is rectangular, which is conducive to the net blocking the ball in the ball passing space 400.

[0037] 3 , in some embodiments, the width X of the training rack 310 is designed according to the following formula: A is the ball release angle and is between 12.7° and 16.7°. n is the number of times the training rack is moved forward per rack width and is a positive integer. H is the height of the training rack. H0 is the height reserved for passing the ball. In other embodiments, n can be a non-integer, such as 2.5, 3.33, etc.

[0038] Referring to FIG3 , as an illustrative example, assuming that the height of the human wall 2000 is 1.83m, the human wall 2000 jumps an average of 0.45m, and reserves a height of about 11cm for half the sphere 1 (taking a standard size 5 ball with a circumference of 69cm as an example). Adding up all the above heights, the preset total height of the bottom of the football 100 is about 2.39m. According to FIFA regulations, the distance between the penalty spot where the football 100 is located and the human wall 2000 is specified as 10 yards, which is about 9.144m. Then, the angle formed between the preset total height at the bottom of the football 100 and the ground relative to the football 100 is about 14.7°, that is, the ball-out angle A is 14.7°. During training, since it is inconvenient to use a higher human wall 2000, the training rack 310 of the present application can be adopted for training. The training rack 310 is proportionally smaller than the simulated human wall 2000 and positioned proportionally closer to the ball 100, allowing the ball 100 to still pass over the training rack 310 at a 14.7° release angle, thereby achieving the desired simulated training effect. A hidden "distance line" is drawn 10 yards between the penalty spot where the ball 100 is located and the original human wall 2000. To position the training rack 310, the rack is first rotated and moved forward along the "distance line" from the penalty spot toward the original human wall 2000 n times, using the rack's frame width X as the unit for one forward movement. Once the rack's height H and the clearance height H0 are determined, the release angle A can be controlled by setting the "placement distance" between the rack 310 and the ball 100. By calculating the "placement distance" / n, the rack's frame width X and the ratio of the rack's width X to its height H can be designed. The specific formula is If you want to control the ball angle A to be 14.7 degrees, and take the frame width X of the training rack 310 as the unit of distance to move forward three times to put it in place, you only need to make That's it.

[0039] 4 , in some embodiments, the height H of the training rack 310 is designed according to the following formula: Where A is the ball release angle and is between 12.7° and 16.7°, n is the number of times the training rack 310 is moved forward in units of the frame height H and is a positive integer, and H0 is the height reserved for passing the ball. In other embodiments, n can be a non-integer, such as 2.5, 3.33, etc. The specific usage can refer to the above-mentioned method of moving in units of the frame width and will not be repeated here.

[0040] Based on this, the present application provides a football training stand with a simple structure, which can be used as a folding ruler and a protractor to quickly place and locate the position. It is easy to use, has a rounded and novel outline, and is highly safe.

[0041] As shown in Figures 5, 6, and 7, the interior of a universal net is composed of vertical ropes and numerous horizontal ropes. Each vertical rope is tied to multiple horizontal ropes in a roughly evenly spaced sequence from top to bottom. A single vertical rope connects to multiple horizontal ropes. The horizontal ropes, after connecting to a vertical rope, are then connected to another vertical rope at roughly evenly spaced intervals. This creates a mesh, with each mesh having a roughly equal area and smaller than a football. Each mesh is typically square, with the ropes forming its four edges. This net is more like a single unit, like a piece of "cloth." If a football hits any part of this "cloth," the entire net is pulled and shaken, making it easy for the ball to become entangled in the cloth and become "stuck" in the mesh. The net is subjected to significant forces, and a ball caught in the mesh can even pull the entire training rack to the ground. The net is also susceptible to damage. (Numbers are unnecessary; they are provided solely to illustrate the comparison of specialized nets.)

[0042] The dedicated human wall ball net in this application has a main body composed of only some vertical ropes 3 without horizontal ropes. Only a few vertical ropes 3 located in the path of the football will be directly touched by the football, and the vertical ropes 3 in other parts will not be touched by the football.

[0043] When the ball hits the vertical ropes 3, the lower parts of the vertical ropes 3 are thrown into the air, but the top parts of the vertical ropes 3 remain firmly connected to the top crossbeam (top beam). At the same time, the ball slides through the vertical ropes 3 and flies away. Afterwards, the vertical ropes 3 shake in place after being hit. Players can observe the shaking of the vertical ropes 3 and know that the ball has touched the net, which can remind players that the ball is too low and hits the "wall". They can improve their shooting skills based on this mistake and avoid making the same mistake again.

[0044] In this scenario, only a small area of ​​the vertical ropes 3 within the dedicated wall net is impacted and disturbed by the ball. The remaining vertical ropes 3 are not subjected to any force from the ball. Therefore, the impact of the ball on the entire net and training frame 1 is minimized, reducing damage to the training frame 1 and the net. The stress on the outer frame of the training frame 1 is also minimized. Furthermore, the cost of replacing a single vertical rope 3 is lower than that of replacing the entire net, thereby reducing product damage and cost.

[0045] After tying a string of vertical ropes 3 to the top beam, when connecting the string of vertical ropes 3 in sequence with one or more horizontal connecting ropes 2, the distance between each vertical rope 3 can be adjusted using the knots on the horizontal connecting ropes 2 so that the distance between every two vertical ropes 3 is smaller than the diameter of a soccer ball.

[0046] This design prevents the ball from slipping out from between the two vertical cords 3 when the dedicated wall net is hit by a soccer ball. This could mislead players into thinking the ball has not been kicked into the net. This design prevents the ball from slipping out from between the two vertical cords 3 due to the sparse distribution of the vertical cords 3 when the net is hit by a soccer ball. This design allows at least some of the vertical cords 3 to be struck by the soccer ball, causing them to swing / dangle. This allows players to clearly see that the ball was kicked too low, automatically reminding them to improve their kicking technique.

[0047] Obviously, the above is only a preferred embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application description and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
