Tennis training device with integrated multiple tilt angles {TENNIS TRAINING APPARATUS HAVING INTEGRATED MULTI-SLOPES}

The present invention relates to a tennis practice device having an integrated multiple inclination angle, and more particularly, the mesh for bouncing a tennis ball is composed of a plurality of inclined surfaces having different inclinations, but the inclined surface is not located at the boundary between the inclined surfaces. It relates to a tennis practice device having an integrated multiple inclination angle that can prevent the tennis ball from jumping irregularly by the frame located at the boundary of the.

Tennis is getting more and more popular in the improvement of personal fitness and hobbies, but to practice tennis, a separate tennis practice area with a tennis court is required.

In order to practice on these tennis courts, many restrictions are imposed both in terms of time and economics, and thus, tennis is not widely available to the general public.

On the other hand, in order to practice tennis, you need a partner to receive the hit ball, so the inconvenience of not being able to practice alone, and to solve this inconvenience, the user has the function of returning the hit ball back to the user A tennis swing exerciser has been proposed.

Conventionally proposed tennis swing exerciser as shown in Figure 1 is a base (C1) and a court (C1) consisting of a tent sheet on the court support frame (2a) supported from the top of the pedestal (1) ), A passage passage formed by the coat body (2) fixed with the upper coat (C2) fixed to the coat support frame (2a) at the top of the coat, and the coat (C1) and the coat (C2). 3b and the tennis ball return part 3 which communicates with the upper end part of the said movement path 3b, and consists of the sealed space in which the opening part 3a which has larger diameter than the tennis ball is formed in the lower side.

In the structure as described above, when the user hits the tennis ball toward the court body 2, the tennis ball hits the court C1 and enters the sealed space forming the tennis ball return part 3 through the moving passage, and then opens. Through the part 3a, it comes out to the coat C1 again.

The tennis ball coming out of the court (C1) is bounced by the recoil plate (4) disposed below the court (C1), the user can repeat the practice by swinging the bouncing tennis ball with a racket.

However, the conventional tennis ball swing exerciser has a problem that noise occurs while the tennis ball impacts the court seat made of cloth. In addition, since the speed of the tennis ball is reduced by the deceleration guide body, it is configured to throw only in a certain direction by using a throwing device, so that the user is thrown only in a certain form regardless of the speed and direction in which the user hits, so that the practice becomes monotonous. there is a problem.

On the other hand, the tennis practice net as shown in Figure 2 (public utility model No. 1999-0020623), the frame 10, the net 20 is coupled to the frame 10 to receive the tennis ball bounced, the frame (10) The lower end has a fixing portion 30 is fixed to the ground so that the frame 10 does not fall by the force of the tennis ball. Since the conventional tennis practice net can bounce the tennis ball hit by the user using the net 20 having elasticity, the tennis practice can be more dynamic than the conventional tennis ball swing exerciser. However, since the net having elasticity is formed in a flat surface, when the tennis ball hits the upper part of the net, it rises excessively, and when it hits the lower part of the net, it hits the floor adjacent to the net. There is a problem that it is difficult to sustain a rally due to the wide range.

Prior to the description, in the various embodiments, components having the same configuration will be representatively described in the first embodiment using the same reference numerals, and in other embodiments, different configurations from the first embodiment will be described. do.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the tennis practice device having an integrated multiple inclination angle according to a first embodiment of the present invention.

In the accompanying drawings, Figure 3 is a block diagram of a tennis practice device having an integrated multiple inclination angle according to the first embodiment of the present invention, Figure 4 is a perspective view of the portion "A" of Figure 3, Figure 5 is an integrated multiple of the present invention It is a block diagram for demonstrating the function of the 5th mesh of the tennis exercise device which has an inclination angle.

The tennis training device having the present invention integrated multiple tilt angle as shown in the figure includes a plurality of meshes (110a, 110b, 110c, 110d, 110e) and a plurality of frames (120) for fixing the mesh, respectively.

The plurality of meshes are to return the tennis ball (B) hit by the user back to the user, each mesh is a grid that is maintained in a stretched state to elastically bounce the tennis ball (B) It can be composed of a wire of the form. In the present embodiment, the first mesh 110a, the second mesh 110b, the third mesh 110c, and the fourth mesh are arranged at different inclinations so as to form a receiving space in which the plurality of meshes are provided with openings at one side thereof. 110d) is described as an example, but the present invention is not limited thereto, and the number of meshes may be adjusted according to necessity, such as a user's physique or use environment.

The first mesh 110a is disposed at a position facing the user with an opening therebetween so that the tennis ball B provided in the first direction A1 is protruded in the second direction A2 by the user's hitting. do.

The second mesh 110b is spaced apart from the first mesh 110a in the second direction A2 so that the tennis ball B protruding from the first mesh 110a is protruded in the third direction A3. It is arranged to be inclined on the upper side of the receiving space.

The third mesh 110c is spaced apart from the second mesh 110b in the third direction A3 so that the tennis ball B protruding from the second mesh 110b is protruded in the fourth direction A4. It is disposed inclined to the other side of the upper receiving space, and may be disposed in a relatively parallel direction with the first mesh (110a).

The fourth mesh 110d is spaced apart from the third mesh 110c in the fourth direction A4 so that the tennis ball B protruding from the third mesh 110c protrudes in the fifth direction A5. So that it is inclined to the lower portion of the receiving space.

Here, the fifth direction A5 may face the user according to the installation angle of the fourth mesh 110d. However, if the time from when the user hits the tennis ball B to the tennis ball B is returned to the user is short, it is difficult for the user to secure time for preparing the next batting posture.

Therefore, when the return time is sufficiently necessary, when the fifth direction A5 is directed toward the third mesh 110c by adjusting the installation angle of the fourth mesh 110d, the fourth mesh 110d is bounced off from the fourth mesh 110d. The tennis ball B returned to the mesh 110c moves from the third mesh 110c in the sixth direction A6 toward the first mesh 110a and then faces the user in the first mesh 110a. It can be made to stick out in seven directions A7. That is, since the time to return the tennis ball (B) to the user is delayed as the movement path of the tennis ball (B) increases in the accommodation space, the user hits the tennis ball (B) to prepare for the next shot position. You will have time.

Meanwhile, the plurality of meshes may further include a fifth mesh 110e disposed above the first mesh 110a to reduce the range of the second direction A2, and the first mesh Since the angle between 110a and the fifth mesh 110e is set to an obtuse angle, the exit angle of the tennis ball B protruding in the second direction A2 may be reduced. Therefore, the tennis ball B may reduce the area of the second mesh 110b, the third mesh 110c, and the fourth mesh 110d, which are installed after the first mesh 110a. Can reduce the range returned.

In addition, the first to fifth meshes 110a, 110b, 110c, 110d, and 110e are arranged in such a manner that ends of a pair of adjacent meshes cross each other, and thus there is no space at a connection portion between the meshes. It is possible to prevent the tennis ball (B) to break off unnecessarily to interrupt the practice.

The plurality of frames 120 fix the edges of the first to fifth meshes 110a, 110b, 110c, 110d, and 110e, respectively, and each frame 120 is arranged to support both sides of the mesh. It includes a pair of side members 120a which are spaced apart from each other, and a connection member 120b for connecting the upper and lower ends of the pair of side members 120a, respectively.

In the side members 120a of the plurality of frames 120, a plurality of frames 120 may be integrally formed as an intersection portion 121 in which portions of adjacent pairs of meshes overlap each other is provided. The intersection 121 is provided at a position spaced toward the center of the side surface from the side end portion of the frame 120.

In addition, the frame 120 is provided with a plurality of through holes 126 that can be installed through the wire constituting the mesh. Therefore, the wire is installed along the through hole 126 formed in the pair of side members 120a facing each other and the through hole 126 formed in the pair of connecting members 120b, and then the wire is tensioned. In the space surrounded by) can be formed a mesh that can bounce the tennis ball (B) elastically.

In this case, the plurality of meshes are arranged in such a way that the ends of a pair of adjacent meshes cross each other, and a portion where the meshes cross each other is supported by an intersection portion 121 of the frame 120, and the intersection portion ( 121 is provided at a position spaced apart from the end of the side member 120a of the frame 120 toward the center of the side member 120a, so that the frame 120 does not exist at the boundary where the meshes intersect. Therefore, it is possible to prevent the tennis ball (B) from being thrown irregularly at the boundary between the mesh.

The operation of the first embodiment of the tennis practice device having the integrated multiple tilt angles described above will now be described.

As shown in FIG. 3, the tennis ball B hit by the user and moved in the first direction A1 bounces elastically after colliding with the first mesh 110a and moves in the second direction A2. do. Thereafter, the tennis ball B moved in the second direction A2 is moved in the third direction A3 by the second mesh 110b and in the fourth direction A4 by the third mesh 110c. The fourth mesh 110d moves in the fifth direction A5, the third mesh 110c moves in the sixth direction A6, and the first mesh 110a moves in the seventh direction A7. To return to the user.

Here, the speed of the tennis ball (B) moving in the second direction (A2) is determined by the striking force of the user, the angle of the second direction (A2) is provided in the first direction (1) provided to the first mesh (110a) It is determined by the angle of A1).

That is, the angle of the seventh direction A7 of the tennis ball B that is finally directed to the user is determined according to the angle of the first direction A1 determined by the hitting direction of the user, that is, the hitting position or the hitting position of the user. In addition, since the speed of the tennis ball (B) provided in the seventh direction (A7) is determined according to the force hit by the user to hit the tennis ball (B), compared to the conventional practice device that the monotonous ball is repeatedly provided with the actual game and The same situation can be realistically implemented.

In addition, the first mesh 110a, the second mesh 110b, the third mesh 110c, the fourth mesh 110d, and the fifth mesh 110e are each formed in a lattice shape, and use a wire that is stretched to the tension. Since the tennis ball (B) bounces elastically, noise is not generated during the collision of the tennis ball (B).

Meanwhile, the second mesh 110b and the third mesh 110c are disposed above the accommodation space between the opening and the first mesh 110a, and the fourth mesh 110d is the opening and the first mesh 110a. Disposed below the accommodation space, and the inclinations of the first to fourth meshes 110a, 110b, 110c, and 110d indicate that the tennis ball B hit by the user toward the first mesh 110a is the second. Preferably, the mesh 110b is configured to return to the user via the mesh 110b, the third mesh 110c, and the fourth mesh 110d.

In particular, the plurality of meshes are each independently supported by the frame 120 to maintain a stable planar shape, so that the tennis ball B may protrude in a predetermined direction.

In addition, since the intersection portion 121 of the frame 120 is disposed at a position spaced apart from the end of the side member 120a of the frame 120 toward the center, the frame 120 may not exist at the boundary between the meshes. have. Therefore, it is possible to prevent the tennis ball B from being thrown out in an unintended direction in the process of bouncing the tennis ball B using a plurality of meshes.

On the other hand, as shown in Fig. 5 (a), when the first mesh 110a consists of a single inclined surface having a predetermined slope, the exit angle at the upper end of the first mesh 110a and the exit angle at the lower end Since this form becomes enlarged, the range of the return path of the tennis ball B becomes gradually large. Therefore, in this configuration, there is a problem in that the areas of the second mesh 110b, the third mesh 110c, and the fourth mesh 110d, which are installed after the first mesh 110a, must be gradually formed.

However, as illustrated in FIG. 5B, a fifth mesh 110e that forms an obtuse angle with the first mesh 110a is further disposed above the first mesh 110a, and the first mesh 110a and the first mesh 110a are disposed. When the five meshes 110e are disposed within the range of the first direction A1, it is possible to prevent the range of the second direction A2 from expanding. Accordingly, the area of the second mesh 110b, the third mesh 110c, and the fourth mesh 110d, which receives the tennis ball B bounced from the first mesh 110a and the fifth mesh 110e, is determined. It is not necessary to gradually design large, and the range of the return path of the tennis ball (B) is reduced, which can provide an advantage of easy to repeat the rally.

Next, a tennis practice apparatus having an integrated multiple inclination angle according to a second embodiment of the present invention will be described.

Of the accompanying drawings, Figure 6 is a perspective view of the tennis practice device having an integrated multiple inclination angle according to a second embodiment of the present invention, Figure 7 is an enlarged view "B" of Figure 6, Figure 8 is a second embodiment of the present invention Figure is a block diagram showing the intersection of the tennis practice device having an integrated multiple inclination angle according to the embodiment.

In the tennis practice apparatus having an integrated multiple tilt angle according to the second embodiment of the present invention as shown in the drawings, the intersection portion 121 provided in the frame 120 is divided from the frame 120 and the frame 120 is formed. It differs from the first embodiment in that it is detachably assembled to.

In detail, the frame 120 having the intersection portion 121 formed at a portion where the mesh intersects the X-shaped intersection portion 121 and the first unit portion 122 assembled to one side of the intersection portion 121. And a second unit part 123 assembled to the other side of the intersection part 121.

On the other hand, since the rest of the configuration except for the frame 120 is the same as the first embodiment, a detailed description of the same configuration is omitted.

As shown in FIG. 7, the first unit 122, the second unit 123, and the intersection 121 have a through hole 126 through which wires constituting a mesh penetrate along a length direction. A plurality of formed at regular intervals (D), the first coupling portion 124 is formed at the end of the first unit portion 122 and the second unit portion 123, the end of the intersection portion 121 A second coupling part 125 is formed to which the first coupling part 124 is detachably assembled.

Meanwhile, in the drawing, the first coupling part 124 is formed in the form of a shaft, and the second coupling part 125 is illustrated as being formed in the shape of a hole into which the first coupling part 124 is inserted. In addition, it is also possible to apply other types of coupling structure that can be repeatedly detachable while maintaining a strong bonding force.

Here, the through hole 126 is disposed at a position biased to one side toward the receiving space in the cross section of the frame 120, the first coupling portion 124 and the second coupling portion 125 is the frame 120 In the cross-section of the heading toward the opposite side of the receiving space. Therefore, in the state where the intersection portion 121 is assembled between the first unit portion 122 and the second unit portion 123, the through hole 126 for installing the mesh wire is formed by the first coupling portion 124 and the first coupling portion 124. Since the second coupling part 125 may not overlap, the installation interval of the mesh wires may be prevented by the first coupling part 124 and the second coupling part 125.

In addition, the through holes 126 formed at the end portions of the first unit portion 122 and the second unit portion 123 may have an interval corresponding to 1/2 of the spaced interval D of the through hole 126 from an end portion thereof. A through hole 126 disposed at a position spaced apart by D / 2) and formed at an end of the intersection portion 121 may have an interval corresponding to one half of a distance D of the through hole 126 from an end portion thereof. Since it is disposed at a position spaced apart by D / 2), it is possible to prevent irregular installation intervals of mesh wires at the assembly portions of the first unit 122, the second unit 123, and the intersection 121. .

Meanwhile, as shown in FIG. 8, the intersections 121 and 121 ′ may determine an angle between an adjacent pair of inclined surfaces, and the intersection angles θ 1 and θ 2 of the intersections 121 and 121 ′ formed in an X shape. ) May be provided in different forms, and the first unit part 122 and the second unit part are selected by selecting any one of the intersection parts 121 and 121 ′ having a desired angle from among the plurality of intersection parts 121 and 121 ′.
