Description

{HITTING PRACTICE DEVICE}

More particularly, the present invention relates to a batting practice device in which a phenomenon in which a ball colliding with a target is prevented from coming back out due to a repulsive force, and no noise or vibration is caused after collision with a target.

Golf and baseball are a way to score points by hitting the ball. To improve the performance of a golf swing or baseball betting, practice to hit the ball precisely in the desired direction is required. There are various types of golf and baseball batting practice machines on the market.

In this regard, Korean Patent Registration No. 1194694 discloses a target device for a golf practice, and Patent Publication No. 1194694 discloses a technique in which a target is integrally joined to a front edge of a target portion printed with a target, A target sheet comprising a protective portion having an opening; A guide hole located at a lower side of the target sheet and penetrating through the opening to guide the golf ball moved downward between the target portion and the protective portion to the outside; A switching means provided on the inner side of the guide groove for detecting movement of the golf ball passing through the guide groove; An output means provided at an outer side of the guide sill or at a side of the target seat or at a tee shot position (ate) where a golf ball is tee shot so that a light is turned on or a corresponding sound is output during operation of the switching means; And power supply means provided inside the guide hole for supplying operating power to the output means during operation of the switching means.

Registration No. 1194694 discloses that when a golf ball tee-shot by an practitioner is hit by a target placed on the rear side of the opening, the target portion printed with the target by the speed of the golf ball flies in the traveling direction of the golf ball, So that the golf ball is moved to the lower part of the space between the target part and the protection part so that the practitioner can simply hit the target with the golf ball, .

However, in the golf practice target device of Patent Publication No. 1194694, a golf ball penetrating through an opening and colliding with a target portion at a high speed is not moved to the lower space between the target portion and the protection portion due to the repulsive force, There was a problem of getting out.

Conventional golf ball and baseball batting exercises, not only in Patent Publication No. 1194694, have a problem in that the ball generates a noise that bounces a few times inside the ball (even if it does not go out through the opening) after colliding with the target or causes vibration of the batting exerciser , Which is a factor that interferes with comfortable batting practice.

In particular, in the batting practice range where a plurality of batting exercises are installed, it is difficult for the practitioner himself to catch the target colliding sound mixed with the noise heard by the ball hitting the target from the surroundings. However, if there are multiple targets, it will interfere with the position of the ball due to the target collision sound.

In addition, in the golf practice target device of Patent Publication No. 1194694, when a golf ball flying at a high speed collides against a target portion, a target portion made of a soft material is deformed into a shape that shakes severely, It is possible to confirm only whether or not the ball has been drawn into the opening, but it has a disadvantage in that it can not grasp accurately the flying orbit.

In addition, since the batting practice using the batter hunting machine is a simple repetition of the same operation of hitting the ball several tens to several hundred times, it is easily disadvantageous to people other than the hunting people who are interested in golf or baseball.

1, 5, and 6, the present invention relates to a batting practice device 10, and more particularly, to a batting practice device 10 that prevents a phenomenon in which a ball colliding with a target comes off again due to a repulsive force, A deformable member 200, an absorbent member 300, a support member 400, and a control unit 500. The grid member 100 includes an elastic member 100, a deformable member 200, an absorbent member 300, a support member 400, and a control unit 500.

The batting practice apparatus 10 of the present invention can be used for batting practice of golf and baseball. In the following, we will explain that it is used for golf batting practice.

1 to 3, the lattice member 100 is configured to form a plurality of passages 101 through which the golf ball B struck in front of the user passes. The horizontal bar 110 and the longitudinal And a bar 120. Referring to FIG. 6, the user hits the golf ball B placed on the front side of the grid member 100 toward the grid member 100 side.

As shown in FIG. 3, a plurality of the horizontal bar 110 and the vertical bar 120 form a plurality of passages 101 through which the golf ball B passes while intersecting each other in a lattice form. The golf ball B struck during the batting practice passes through the passageway 101 formed between the horizontal bar 110 and the vertical bar 120.

The horizontal bar 110 and the vertical bar 120 are formed in a bar shape that is sufficiently thinner than the golf ball B. When the horizontal bar 110 and the vertical bar 120 are formed to have a thickness sufficiently thinner than the golf ball B, the golf ball B struck during the stroke practice bumps against the horizontal bar 110 or the vertical bar 120 (Not exactly against the center portion of the golf ball B) passes through the passageway 101 while being struck against the horizontal bar 110 or the vertical bar 120.

As shown in FIG. 2, the grid member 100 is installed in a suspended form on the support member 400. More specifically, the lattice member 100 is coupled to the support member 400 at its upper edge portion, and its lower end is spaced from the support member 400.

1 to 3, the deformable member 200 is configured to be elastically deformed by the kinetic energy of the golf ball B passing through the passageway 101. The passageway 101 of the grid member 100 Respectively.

As shown in Fig. 3, the deformable member 200 is made of a resiliently deformable cloth material and is cut to a size corresponding to the area of the passageway 101, as shown in Fig. 4, Are coupled to the horizontal bar 110 and the vertical bar 120. In Fig. 4, the connecting portion of the deformable member 200 and the lattice member 100 is shown by a dotted line.

As shown in FIG. 3, the hit golf ball B always strikes the deformable member 200 in the process of passing through the passageway 101. In this process, the deformable member 200 is elastically deformed in a flapping manner by the kinetic energy of the golf ball B (with its upper end and side end joined to the grid member 100).

The deformable member 200 is provided for each of the passages 101 and deformed by only one of the kinetic energy of the golf ball B passing through the one of the passages 101. Therefore, The user can grasp the trajectory of the golf ball B visually and accurately.

Even if the golf ball B collides with the right upper end of the deformable member 200 in the state shown in Fig. 3, the golf ball B is deformed by the deformable member 200 200 to move rearwardly of the grid member 100 through the space between the horizontal bar 110 and the vertical bar 120. [ The kinetic energy of the golf ball B passing through the passage 101 of the grid member 100 is reduced in proportion to the amount of deformation of the deformable member 200.

After the golf ball B has passed through the passageway 101, the deformable member 200 returns to the state in which the passageway 101 is closed. The golf ball B passing through the passageway 101 is prevented from escaping from the passageway 101 through the passageway 101 even after the passageway splashes toward the passageway 101 after colliding with the absorbent member 300. [

Since most of the kinetic energy is absorbed by the elastic deformation of the deformable member 200 and the absorbent member 300 after the golf ball B collides with the absorbent member 300 toward the passageway 101, (200) can block the departure of the golf ball (B) through the passageway (101).

5 and 6, the absorbing member 300 absorbs the kinetic energy of the golf ball B that has passed through the passageway 101 to drop the golf ball B, (310) and a second absorbing member (320).

5, the first absorbent member 310 is configured to form an inclined surface in which the golf ball B passing through the passageway 101 slants obliquely, and extends rearward from each longitudinal bar 120 . The first absorbent member 310 and the second absorbent member 320 are made of rubber, silicone, or cloth material that absorbs kinetic energy of the golf ball B by its own elastic deformation.

The golf ball B having passed through the passageway 101 firstly strikes the sloped surface of the first absorbent member 310. Referring to the state shown in FIG. 5, the golf ball B is moved in a form of being leftwardly moved along an inclined surface by an inertial force after hitting an inclined surface. In this process, the first absorbent member 310 is elastically deformed, and the kinetic energy is decreased as the golf ball B is proportional to the deformation amount of the first absorbent member 310. [

As shown in FIG. 5, the second absorbent member 320 is configured to connect the vertical bar 120 and the inclined surface, and is formed to extend rearward from each vertical bar 120. Hereinafter, for easy understanding of the invention, a portion where the second absorbing member 320 and the inclined surface are combined is referred to as an 'intersection A'.

The first absorbent member 310 and the second absorbent member 320 each extend from a pair of adjacent vertical bars 120 and are joined to each other at the intersection A. Accordingly, the first absorbent member 310 and the second absorbent member 320 are spaced apart from each other by a space (hereinafter, referred to as 'absorbent space 301') which blocks the rear of the passageway 101 from behind a pair of adjacent vertical bars 120, . The absorption space 301 connects the plurality of passages 101 in the longitudinal direction between a pair of adjacent vertical bars 120.

5, the golf ball B passing through the passageway 101 and striking the inclined surface of the first absorbent member 310 and then rolling along the inclined surface toward the intersection A is sandwiched between the first absorbent member 310 The kinetic energy of the golf ball B is converged to 0 in the process of being sandwiched between the first absorbing member 320 and the second absorbing member 320. The golf ball B has the kinetic energy converged to zero, (See Fig. 6).

The process of sandwiching the golf ball B between the first absorbing member 310 and the second absorbing member 320 at the intersection A after colliding with the inclined surface of the first absorbing member 310 is performed at a very high speed Thus, the batting practice apparatus 10 of the present invention solves the problems of the conventional batting exerciser technique in which significant noise and vibration occur after collision with the target.

1, the frame 410 is a structure for forming the skeleton of the support member 400 and includes a lattice member 100, a deformable member 200, and an absorbent member (not shown) 300). The frame 410 includes a coupling frame 411 to which the edges of the grid member 100 are coupled. The coupling frame 411 is coupled to the edge of the grid member 100 via the side cover 421 while being supported by the frame 410. [

The cover 420 is configured to prevent the golf ball B from entering and exiting in the direction other than the front of the grid member 100. The cover 420 includes a side cover 421, a rear cover 422, a bottom cover 423, 424, and a top cover 425. As shown in Fig. The side cover 421, the rear cover 422, the bottom cover 423, the inclined cover 424 and the top cover 425 are coupled to the frame 410 by a hanger K and a sleeve.

The side cover 421 and the top cover 425 are provided on the side surface and the upper surface of the lattice member 100, the deformable member 200 and the absorbent member 300. The rear cover 422 is provided behind the absorbing member 300 to shield the back of the absorbing member 300 from the outside.

5 and 6, the bottom cover 423 and the slope cover 424 form sloped faces F1 and F2 at the bottom of the support member 400. As shown in FIG.

The golf ball B having the kinetic energy converged to 0 between the first absorbent member 310 and the second absorbent member 320 falls vertically in the absorption space 301, The ball B is first rolled down (see Fig. 6) by the potential energy along the first sloped surface F1 formed on the upper surface of the bottom cover 423, And is moved along the sloping surface F2 toward the drawing rail 430 (see Fig. 5).

The drawer rail 430 is provided at the outermost end of the inclined cover 424 for pulling forward the golf ball B rolling along the sloped faces F1 and F2. The golf ball B drawn out to the user through the drawing rail 430 is collected and reused by the user.

7, the rear cover 420 may connect the rear ends of the first absorbing members 310 to each other. When the rear cover 420 connects the rear ends of the first absorbent member 310 to each other, the first absorbent member 310 is prevented from flowing between the lattice member 100 and the rear cover 420, The first absorbing member 310 and the second absorbing member 320 are elastically deformed to absorb the kinetic energy of the golf ball B while the first absorbing member 310 and the second absorbing member 320 are taut The amount of elastic deformation of the first absorbent member 310 by the first absorbing member 310 is lowered to lower the vibration of the impact practicing apparatus 20. [

4, the deformation member 200 may be provided with a sensing sensor 230 and a light emitting member 240 for sensing whether the golf ball B passes through the passageway 101. It should be understood that the sensing sensor 230 and the light emitting member 240 are connected to the control unit 500 and the battery (not shown) through a wire, though the wire is not shown in the drawing.

When the detection sensor 230 and the light emitting member 240 are installed on the deformable member 200, the deformable member 200 includes a first deformable member 210 and a second deformable member 220 which are overlapped with each other . The first deformable member 210 and the second deformable member 220 are made of silicon or cloth and joined together in a superposed state.

The sensing sensor 230 includes an inertial sensor interposed between the first deformable member 210 and the second deformable member 220 to sense the vibration of the deformable member 200. Therefore, the sensing sensor 230 senses when the deformable member 200 is elastically deformed by the kinetic energy of the hit golf ball B.

The light emitting member 240 is provided as one or more LED lamps and interposed between the first deformable member 210 and the second deformable member 220. Since the first deformable member 210 and the second deformable member 220 are made of silicon or cloth material capable of transmitting light, when the light emitting member 240 emits light, the light transmits through the first deformable member 210 And is emitted forward.

The control unit 500 blinks the light emitting member 240 in conjunction with the signal of the detection sensor 230, thereby making it possible to attract interest to a user who is not particularly interested in golf or baseball.

The control unit 500 turns on the light emitting member 240 provided on the at least two deformable members 200 of the plurality of the deformable members 200 so that the user can press the deformable member 200 with the light emitting member 240 lit The light emitting member 240 of the struck deformable member 200 is turned off after sensing it through the detection sensor 230. The user concentrates on the hit of the golf ball B to match all the deformable members 200 that emit light.

As another example, the control unit 500 turns on the light emitting member 240 installed on one deformable member 200 randomly among the plurality of deformable members 200, and when the user presses the deformable member 200 The light emitting member 240 of the struck deformed member 200 is turned off and the light emitting member 240 provided in the other deformation member 200 is turned on.

As shown in FIG. 4, an application for exchanging data with the control unit 500 and controlling the operation of the light emitting member 240 may be installed in the user's smartphone SP.

A technique for transmitting data using a short distance communication such as Wi-Fi in a smart phone (SP), and a technique for producing an application for outputting transmitted data are well known in the art, so a detailed description thereof will be omitted.

The application stores and outputs the hitting information of the golf ball B based on the signal of the detection sensor 230. The user checks the hitting practice history in real time through data accumulation of the application and performs batting practice.

The user can also select a method of blinking the light emitting member 240 in response to the signal of the detection sensor 230, that is, a method of hitting the deformable member 200 with the golf ball B through the application . Thus, a single or a plurality of users can play a game striking the deformable member 200.

According to the present invention, as the deformable member elastically deforming due to the kinetic energy of the ball passing through the passageway is coupled to the grid member, the phenomenon that the ball colliding with the target is prevented from coming out again due to the repulsive force is prevented, It is possible to provide a batting practice apparatus which can be visually grasped accurately.

Further, as the kinetic energy converges to 0 in the process of moving the ball passing through the passage along the inclined surface and sandwiched between the first absorbent member and the second absorbent member, a batting practice that does not cause noise or vibration after collision with the target Thereby providing a device.
