Description

Shooting device that can control the shooting trajectory

The present invention relates to a shooting device capable of controlling the shooting trajectory.

In general, a shooting device that fires balls is one that allows balls to be fired continuously by machines rather than people. For example, in order to develop the individual skills of those who exercise using various balls such as balls or volleyballs, an assistant such as a manager or coach distributes the balls or volleyballs to each player's training position by kicking them with their feet or throwing them with their hands. A method to double the training effect is being used. However, when exercising according to this conventional method, the opponent, i.e. an assistant, must always play an assisting role, and the assistant must be a person who has the skill to accurately distribute the ball to the player's required position to ensure smooth training. You can proceed. Therefore, a lot of manpower is consumed, and as the assistant has to deal with many players, it is difficult to kick or throw the ball in a certain direction and angle, so efficient practice effects cannot be expected. Accordingly, the demand for effective training in consistently and repeatedly providing balls with intended trajectories is gradually increasing, and there is a need for devices that can create situations in which balls are provided with various trajectories.

One embodiment of the present invention aims to provide a ball that repeatedly maintains a constant trajectory.

One embodiment of the present invention aims to implement various trajectories by combining the height, left and right, and distance of the ball.

The present invention relates to a shooting device capable of controlling a shooting trajectory, comprising: a pair of rotating assemblies that launch a ball through rotational force; A body supporting the rotating assembly; A guide connected to the body but extending in the same line as the direction in which the ball is launched; A folding leg that can extend toward the ground on one side of the body; And a rear leg connected to the guide so as to be rotatable. A shooting device capable of controlling a shooting trajectory is provided, including a rear leg.

In addition, a pair of folding legs is provided, each of which is connected to the lower part of the rotating assembly to determine the first launch angle at which the ball is launched based on the ground.

Additionally, the rear leg is fixed within the rotation range, so that the second launch angle at which the ball is launched relative to the ground can be determined.

In addition, it may further include a control unit that independently controls the rotation speed of the pair of rotation assemblies.

Additionally, the trajectory of the ball may be determined by the rotation speed, first launch angle, and second launch angle of the pair of rotation assemblies determined by the control unit.

According to one embodiment of the present invention, a shooting device capable of controlling a shooting trajectory that can repeatedly provide a ball maintaining a constant trajectory can be provided.

According to one embodiment of the present invention, it is possible to provide a shooting device that can adjust a shooting trajectory that can implement various trajectories by combining the height, left and right, and distance of the ball.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is only an example and the present invention is not limited thereto.

In describing the present invention, if it is determined that a detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definition should be made based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following examples are only a means to efficiently explain the technical idea of the present invention to those skilled in the art in the technical field to which the present invention pertains.

Figure 1 is a perspective view of a shooting tee 100 according to an embodiment of the present invention.

Referring to FIG. 1, an embodiment of the present invention relates to a shooting tee 100 (hereinafter referred to as shooting tee 100) capable of controlling the shooting trajectory, and includes a pair of shooting tees 100 that launch the ball 10 through rotational force. A rotating assembly 110, a body 120 supporting the rotating assembly 110, a guide 141, and body 120 connected to the body 120 and extending in the same line as the direction in which the ball 10 is launched. It includes a foldable leg 125 that can extend toward the ground (G) on one side and a rear leg 142 that is connected to the guide 141 and is rotatable.

Specifically, in the shooting tee 100, a pair of rotating assemblies 110 are rotated by a control unit (not shown), and a ball 10 is provided between the rotating assemblies 110, so that the rotating assembly 110 rotates the ball 10. ) can be compressed and discharged. The rotating assembly 110 may be provided at regular intervals, and the rotating assembly 110 may be positioned between predetermined balls 10 formed in the body 120. Control of the rotating assemblies 110 provided as a pair can be performed independently. For example, when one rotation speed is controlled by the control unit to be 500, the other rotation speed may be controlled to be 400 rotation speed. Of course, this may be the number of rotations calculated based on the input value entered by the user.

These different rotation speeds can apply rotation to the ball 10 when the ball 10 is launched, which reduces the pressure around the ball 10 after the ball 10 is launched by the shooting tee 100. By forming them differently, the direction of movement of the ball 10 can be changed. Therefore, the trajectory of the ball 10 can be changed by varying the rotation speed of the rotation assembly 110 by the control unit.

Furthermore, the rotation speed may be a factor in the trajectory change of the ball 10, and the trajectory change may occur depending on the inclination of the shooting tee 100. The slope can be divided into a first launch angle (S2) and a second launch angle (A), which will be explained in more detail below.

Meanwhile, the surface of the rotating assembly 110 in contact with the ball 10 may have a certain amount of elasticity. Here, the surface refers to the outer peripheral surface of the shooting wheel that can be in contact with the ball 10. The outer peripheral surface of the shooting wheel may have predetermined elasticity and hardness to prevent slippage with the ball 10. As a preferred example, the material forming the outer peripheral surface of the shooting wheel may be a material containing at least urethane, and the hardness is, as an example, 40 to 50 based on the results measured by a commercially available Teclock rubber hardness tester (GS-706S). You can have

Here, in the case of the hardness of 40, the elasticity ratio is formed to be higher to prevent the felt, etc. formed on the surface of the ball 10 from falling off and the lifespan of the ball 10 is not reduced. In other words, the hardness is made relatively low to prevent slip with the ball 10 due to high hardness. On the other hand, setting the hardness to 50 is to increase the pressing force on the ball 10 through the shooting wheel in the case of soccer balls and volleyball balls that do not have loose elements such as felt on the surface of the ball 10.

Figure 2 is a bottom perspective view of the shooting tee 100 according to an embodiment of the present invention.

Referring to FIG. 2, as described above, the factors that determine the trajectory of the ball 10 are the rotation speed of the rotating assembly 110, the first launch angle (S2), and the second launch angle (A). The first launch angle (S2) may be an angle at which the ball 10 is launched by changing the inclination by adjusting the height of the rear side based on the front-to-back direction of the shooting tee 100, and the second launch angle (A ) may be the angle at which the ball 10 is launched by changing the inclination by adjusting the height of one or more of the left and right sides based on the left and right directions of the shooting tee 100.

The folding leg 125 coupled to the illustrated body 120 is a component that determines the formation of the second launch angle A, and can be rotated in the direction of the indicated arrow, and the two folding legs 125 coupled to both sides ) can be developed independently. The folding leg 125 can be coupled with a hinge so as to be rotatable with the body 120, and can be fixed in a deployed or non-deployed state.

Additionally, the rear leg 142 rotatably coupled to the guide 141 can be fixed within a rotatable range. That is, it can be selectively fixed so that the first launch angle (S2) can be freely determined. As shown, when the folding leg 125 is not deployed, the wheel 130 connected to the body 120 on the front side of the shooting tee 100 may be in contact with the ground (G). In this state, the second launch angle (A) is not formed and only the first launch angle (S2) can be adjusted. The “non-formation” may cause the second launch angle (A) to converge to the horizontal (if the ground (G) is horizontal).

Of course, even when both of the pair of folding legs 125 are deployed, the horizontal direction may not be formed. It will be described in more detail with reference to Figure 3 below.

Figure 3 is a front view of the shooting tee 100 according to an embodiment of the present invention. Figure 3 (a) is a front view of the shooting tee 100, and Figure 3 (b) is a shooting tee 100 at the second launch angle. This is a front view tilted at degree (A).

Referring to FIG. 3, when the folding leg 125 is not deployed, the ball 10 can be launched toward the front. At this time, when one folded leg is deployed as shown in FIG. 3(b), a second launch angle A is formed and the ball 10 can be launched. As described above, the rotation speed and the second launch angle (A) of the rotating assembly 110 are factors that determine the trajectory of the ball 10, and in a state where the second launching angle (A) is formed, a pair of rotating assemblies ( 110) The trajectory of the ball 10 can be determined by varying the number of rotations. The trajectory of the ball 10 changes in the direction of movement in the air due to a pressure difference depending on the number of rotations of the ball 10, and is affected by gravity.

When the second launch angle (A) is formed by the folding leg 125, the angle formed between the shooting wheel, which is the surface in contact with the ball 10 of the rotating assembly 110, becomes the second launch angle (A), Depending on the number of rotations implemented by each rotation assembly 110, the ball 10 may be moved in the opposite direction of gravity or may be rapidly dropped in the direction of gravity. Accordingly, the trajectory of the ball 10, which can be adjusted according to the second launch angle A, can be configured in various ways.

Figure 4 is a side view of the shooting tee 100 according to an embodiment of the present invention, Figure 4(a) is a side view with the launch angle formed in a direction parallel to the ground (G), and Figure 4(b) is a side view of the shooting tee 100 according to an embodiment of the present invention. This is a side view with the ground (G) and the first launch angle (S2) formed.

Referring to FIG. 4, the rear leg 142 is fixed within the rotation range, so that the first launch angle S2 at which the ball 10 is launched based on the ground G can be determined. As described above, the first launch angle S2 may be formed by the rear leg 142 coupled to the guide 141. The rear leg 142 is rotatably connected to the guide 141 so that the height of the guide 141 from the ground (G) can be adjusted by rotation. For example, as shown in FIGS. 4 (a) and 4 (b), the angle formed by the rear leg 142 with the ground (G) is rotated based on the rotation center connected to the guide 141, and the rear leg 142 rotates. Selective fixation is possible within the possible angle range.

When the first launch angle S2 is formed as shown in FIG. 4(b) by selective fixation in this way, the direction of movement of the ball 10 to the left or right is determined by the rotation speed of the rotation assembly 110 controlled by the control unit. This may be decided. As previously explained, in the case of FIG. 3, the second launch angle (A) may have a certain effect on the movement of the ball 10 in the vertical direction, but as in the example shown in FIG. 4, the second launch angle A may have a certain effect on the rotation of the rear leg 142. When forming the second launch angle (A), the relative position of the pair of rotation assemblies 110 does not change, so it may affect the movement of the ball 10 to the left and right. In other words, the factors that cause the ball 10 to move in the vertical direction may be limited to gravity and the second launch angle (A).

However, when the trajectory of the ball 10 is formed by simultaneously applying the first launch angle (S2) and the second launch angle (A), selective control can be performed in the vertical and horizontal directions (left and right). As described above, this is due to the rotation speed of the rotating assembly 110, the first launch angle (S2), and the second launch angle (A), and does not take into account external factors such as wind or gravity.

Figure 5 shows the shooting tee 100 in a state in which a first launch angle (S2) and a second launch angle (A) are formed by one folded leg 125 and the rear leg 142 according to an embodiment of the present invention. This is a perspective view showing .

Referring to FIG. 5, a first launch angle S2 and a second launch angle A may be formed due to the intervention of one deployed folded leg 125 and the rear leg 142. At this time, a single point of one wheel 130, the folding leg 125 on the opposite side of the wheel 130, and the rear leg 142 may be in contact with the ground G. The point where the rear leg 142 touches the ground (G) may be the right end when the folding leg 125 located on the left is deployed, and this provides support against the reaction that occurs at the moment of launching the ball 10. It can be. Of course, when the folding leg 125 located on the right is deployed, it can be the left end of the rear leg 142.

In this state, when the first launch angle (S2) and the second launch angle (A) are formed, the user can selectively determine the movement trajectory of the ball 10 according to left and right and elevation.

Figure 6 shows the trajectory of the ball 10 launched from the shooting tee 100 in one embodiment of the present invention, and is a diagram showing the trajectory reflecting the first launch angle (S2) and the second launch angle (A).

Referring to FIG. 6, the trajectory of the ball 10 can be determined by the rotation speed, first launch angle (S2), and second launch angle (A) of the pair of rotation assemblies 110 determined by the control unit. . Among these, the direction can be determined as top, top right, right, bottom right, bottom, bottom left, left, top left, depending on the combination of the three conditions, just by combining the conditions of the second launch angle (A) and the rotation speed, The degree of displacement formed to the left and right may be determined depending on the difference in rotation speed between the rotating assemblies 110, and the distance at which the ball 10 moves in the firing direction D1 may be determined depending on the height of the rotation speed.

Although representative embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims described later but also by equivalents to the claims.
