Description

Ball game exercising device

Technical Field

The present invention relates to a ball game exercise device, and more particularly, to a ball game exercise device which launches a ball so that various ball games such as: practice of kicking balls supplied from the outside to the inside of the course; directly hitting a ball falling into the court from above and carrying out an attacking spiking exercise; practice of catching the ball in the air with hands and shooting a basketball, etc.

Background

In general, various exercise assisting devices are used for ball games such as soccer, volleyball, and basketball using balls (balls) in order to improve the techniques of attack and defense of players. In the case of using the exercise assisting device, fatigue of a game instructor, i.e., a coach or a general coach or the like can be reduced, and players can easily acquire various techniques in a short time. As an example of a soccer ball, there may be a volleyball shot, a groundball shot, a headball shot, etc., which receives a ball passing from a goal line or a corner ball direction and kicks the ball (goal). Examples of such ball game practice assisting devices include japanese patent laid-open publication No. 9-276463 (1997.10.28) "ball launching device" (hereinafter referred to as "patent document 1") and united states of america US8,371,964B2(2013.2.12 "registration)" volleyball smash practicing device "(hereinafter referred to as" patent document 2 ").

The "ball launching device" disclosed in patent document 1 is configured to launch a ball by a rotational force of pitch rollers by throwing the ball between two pitch rollers (pitch rollers) rotated by two motors. Thus, when the repeated use is continued, there is a problem that the emission angle is not fixed, and there is inconvenience as follows: many balls (balls) to be shot need to be collected manually and put into the ball accommodating body. Further, the "ball launching device" described in the patent document 1 linearly launches a ball at a high position, so that there are many inconveniences in practicing various ball game items.

The foot volleyball is the only ball game originated in korea, and is a game of winning or losing scores by putting a net in the middle between two teams and passing the ball to the other using the head and feet, but the existing "ball launching device" disclosed in the patent document causes the ball to be thrown between two spaced rollers and to be launched forward, so that there is a problem of hitting the net directly, etc., and the equipment is very expensive, so that there are many problems when used in general life sports, sports activities. The problem still arises in volleyball sports with similar rules of competition to foot volleyballs. In other words, for example, the "ball launching device" of patent document 1 is configured to be able to adjust only the horizontal direction in which the ball flies and the inclination angle of the shot ball, and thus cannot improve the ball game technology such as basketball, volleyball, and volleyball, in which the ball dropped from a high ground direction to the ground is hit by the body such as the hand and foot, and the ball is thrown.

The volleyball smash practice device disclosed in the patent document 2 is configured such that balls (ball) accumulated inside are supplied from a hopper (hopper) to an inclined ramp (ramp), and the balls are fixed (hold) to the head (head) of a discharge tube (strobe) coupled to the end of the ramp. If a player hits the balls fixed to the pair of discharge heads of the discharge tube with a hand, the balls jump forward while the discharge heads are separated, and the balls supplied from the ramp are fixed to the discharge heads of the discharge tube. However, the ball dispensing device disclosed in patent document 2 fixes the practice balls supplied from the slide table at the tail portion of the discharge tube, and therefore has a problem that the following practice cannot be performed: not only can be used for catching a static ball, but also can be used for hitting a ball flying from the air or ball-catching and then throwing out and other ball exercises. In other words, a practice similar to basketball cannot be performed, and a practice of kicking (KICK) or shooting (shoot) a ball flying from the air and throwing (toss) the ball in a volleyball cannot be performed.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. However, it should be understood that the present invention can be realized in a plurality of different forms, and is not limited to the described embodiments. And it should be noted that the embodiments of the present invention described below are intended to fully convey the concept of the present invention to those skilled in the art. In addition, the present invention is used to practice the footvolleyball game of the inherent ball game items of soccer, volleyball, basketball, and koreans. Although the specifications of the ball field and the names of the lines drawn on the ball field are different from each other in the soccer field, the basketball, the volleyball and the footlet, the half line of the soccer ball, the center line of the basketball, the center line of the volleyball and the center line of the footlet are drawn at the center of the game field, and the lines drawn at the center are all divided into two parts, which are the same.

Referring to fig. 1 to 5, a ball launching device 100 according to the present invention will be explained. Referring to fig. 1 to 4, the ball launching device 100 includes a space portion of a certain size in the interior of a main body 102, and one side, preferably, the front side of the main body 102 is provided in an open structure, and a practice ball launcher 105 for launching a practice ball is located in the space portion. In this case, a plurality of components for rotating the practice ball emitter 105 in the left-right direction and in the up-down direction and operating the practice ball emitter 105 are built in the body 100 and are closely connected to each other in terms of operation, and the internal components and the operation relationship thereof will be described later. In the present invention, the practice ball refers to a normal soccer ball or the like that is actually used. Further, an image pickup device 1(CAM1) and an image pickup device 2(CAM2) are provided at the front and the side of the practice ball launching device 100, respectively. The image capturing devices (CAM1, CAM2) capture images of subjects located in front of and on the side of the main body 102, and acquire image information corresponding to the images.

Although not shown in the drawings, the lower end of the body 102 of the practice ball launching apparatus 100 may be provided at the edge portion with a wheel for movement, in which case, in order to fix the body 102, a fixing means of a known form for preventing rotation thereof may be additionally provided at either front or rear side of the wheel. Further, it is preferable that the front side wheels are provided in a freely rotatable known structure so as to make it possible to switch directions in all directions when the main body 102 is moved.

A ball receptacle 104 is coupled to an upper side of the body 102, and the ball receptacle 104 has an outer wall having a certain size for receiving the practice ball. The ball receptacle 104 is made in the shape of a rectangular barrel opened up and down, and may be constructed in a net structure so that the amount of the practice balls loaded can be easily recognized with the naked eye.

An inflow port 107 having a predetermined size is formed on the upper surface of the body 102 so that the practice ball supplied from the ball container 104 can flow into the body 102. The upper surface of the body 102 is provided with a downward inclined surface of a predetermined angle toward the inflow port 107 so as to facilitate the inflow of the practice ball. At this time, the body 102 and the ball receiver 104 coupled to the upper portion thereof may be coupled by various methods. For example, the insertion groove may be formed on an edge of an upper surface of the body 102, and the insertion protrusion may be formed on a lower edge of the ball receptacle 104, and the ball receptacle 104 may be mounted on an upper portion of the body 102 while the insertion protrusion is inserted into the insertion groove.

Although not shown in the drawings, an operation switch, a display device for displaying an operation, and an operation key button for setting an operation mode may be provided outside the main body 102, and may be provided in the form of a touch panel as an example.

In the present invention, the practice ball emitter 105 provided in the space portion of the main body 102 receives a supply of practice balls from the ball container 104 coupled to the upper portion of the main body 100 and emits the same. In order to transfer the practice ball, a connection pipe (bellows) 116 having a predetermined diameter is introduced, which extends from a lower portion of the inflow port 107 formed in the inclined surface 103 of the body 100. The connection pipe 116 is connected to an inflow hole 115, and the inflow hole 115 is opened at an upper portion of a front portion of the hollow body 114 shown in fig. 4 constituting the practice ball emitter 105.

As shown in fig. 5, the practice ball flowing into the inflow hole 115 of the hollow body 114 is placed at the launch site. At this time, since the end of the hollow body 114 is formed with the convex portion 114a formed in an arc shape (round) inward, the practice ball flowing into the inflow hole 115 does not flow out of the hollow body 114 as a projectile without being hit. Further, a sensor for discriminating the presence or absence of a practice ball is provided at an end of the hollow body 114, and a controller (MPU) configured as shown in fig. 6 is provided. As the sensor, various sensors such as a photo sensor (photo sensor) can be used.

The hollow body 114 is coupled to an upper portion of a coupler launcher 112 provided at a lower portion thereof, and both side surfaces of the coupler launcher 114 are rotatably coupled to the rotating bracket 110 provided at the lower portion thereof. More specifically, a rack gear (rackstar) 118 is integrally provided at one side surface of the coupling-launching bracket 112, and a driving gear 119 is provided at one side end of the rack gear 118 and the coupling-launching bracket 112 in an engaged state with each other, so that the hollow body 114 can be rotated up and down by a tilting motor 117 connected to the driving gear 119. The rotation bracket 110 is fastened and coupled to a rotation plate 128, which is provided at a lower portion thereof and coupled to a rotation shaft of the rotation motor 120, by a screw, so that the rotation bracket can be rotated left and right by driving the rotation motor 120.

As described above, the practice ball launcher 105 of the practice ball launching apparatus 100 of the present invention can launch the practice ball located at the end of the hollow body 114 in the upward or leftward direction by the left-right rotation of the rotating bracket 110 and the up-down rotation of the launcher 112.

The practice ball flowing into the hollow body 114 is shot in a forward direction by the operation of the cylinder 130 coupled to the rear end of the hollow body 114. As shown in fig. 5, a piston 132 of the cylinder 130 is inserted inside the hollow body 112, and a striking plate 134 is coupled to an end of the piston 132. At this time, the air cylinder 132 may use a hydraulic or pneumatic cylinder, but in order to launch the exercise ball further, a hydraulic cylinder is preferably used.

The hydraulic cylinder 132 includes a hydraulic pressure inflow port connected to the discharge port of the nitrogen tank 144 through a hydraulic pressure discharge solenoid valve 150, and a hydraulic pressure discharge port connected to the hydraulic tank 140 through a hydraulic pressure recovery solenoid valve 146, as is conventional. The hydraulic pump 142 is connected between the hydraulic tank 140 and the nitrogen tank 144, and at this time, the hydraulic pressure supply solenoid valve 148 is connected to the hydraulic pump 142 and the nitrogen tank 144. At this time, a nitrogen pipe filled with nitrogen is included inside the nitrogen tank 144, and a pressure gauge for detecting a nitrogen pressure of the nitrogen pipe is included. When the hydraulic pressure is supplied to the nitrogen tank 114 having the above-described configuration, the pressure is applied to the nitrogen pipe in proportion to the amount of the hydraulic pressure, and the internal pressure of the nitrogen pipe is increased. The information of the increase of the internal pressure is supplied to a controller (MPU).

The operation of the hydraulic circuit configured as described above will be briefly described as follows. To cause the piston 132 of the cylinder 30 to project in the forward direction, the controller drives the hydraulic pump 142 in a state where the supply solenoid valve 148 is opened, and supplies the hydraulic pressure in the hydraulic tank 140 to the nitrogen tank 144. If the amount of hydraulic pressure supplied into the nitrogen tank 140 increases due to continuous pumping, pressure is applied to the nitrogen pipe provided therein, and the pressure increase information is provided to the controller. If the pressure sensing information of the nitrogen pipe has a pressure value set in advance, the operation of the hydraulic pump 142 is stopped and the supply solenoid valve 148 is closed. This makes it possible to see a state in which the nitrogen tank 148 is hydraulically filled with high pressure.

If a transmission command is inputted to the controller from the outside (touch panel) or a transmission cycle set in advance by a program, the controller opens the discharge solenoid valve 150 for a certain time. When the discharge solenoid valve 150 is opened by the operation, the hydraulic pressure filled in the nitrogen tank 144 with high pressure is supplied to the hydraulic pressure inflow port of the cylinder 130, so that the piston 130 in the cylinder 130 is protruded in a forward direction, and the striking plate 134 attached to the end thereof strikes the practice ball placed on the end of the hollow body 114 by the operation and is shot in the forward direction.

When the controller that opens and drives the discharge solenoid valve 150 for a certain period of time opens the recovery and

supply solenoid valves

146 and 148 and drives the hydraulic pump 142, the hydraulic pressure charged in the cylinder 130 is recovered to the hydraulic tank 140, and the piston 132 enters the interior of the cylinder.

The controller controls not only the driving of the hydraulic circuit described above but also the rotation of the rotation motor 120 coupled to the lower portion of the rotation bracket 110 and the rotation of the tilt motor 117 coupled to the side surface, so that the end portion of the hollow body 114 can be adjusted to be oriented in the left-right or up-down direction.

Fig. 6 is a block diagram of a launching controller of a ball launcher according to an embodiment of the present invention, which is provided in an inner space portion of a main body 102 of a practice ball launching device 100. Referring to fig. 6, the launch controller is provided with image capture devices 1, 2(CAM1, CAM2) illuminating the court 10 on at least one or more of the four faces of the main body 102. The two image capturing devices (CAM1, CAM2) are respectively arranged to photograph the front and half-line of the practice ball launching device 100 from which the ball is launched. The touch panel (TS) is provided on any one of the side surfaces of the main body 102, and as described above, an operation switch, a display device for displaying an operation, and a key button (key button) for setting an operation mode are provided on the touch panel.

Information of user's selection behavior (manual, automatic, image capture device mode, direction setting mode, penalty ball mode, heading mode, shooting mode setting, etc.) provided from the Touch Screen (TS) and video signals photographed from the image capture devices (CAM1, CAM2) are input to a controller (MPU). The controller (MPU) controls the overall operation of the practice ball launching device 100, and is generally classified into a manual mode, an automatic mode, and an image capturing device mode.

In the case of the manual mode, the controller (MPU) drives the rotation motor 120 and the tilt motor 117 according to an input of a direction setting key (vertical, horizontal) from the touch screen and sets a launching direction of the practice ball launcher 105, and causes the cylinder 130 of the hydraulic device to operate and launch the practice ball through the solenoid valve driving part (SOD) according to a launching command from the touch screen. In case of the automatic mode, the controller (MPU) drives the rotation motor 120 and the tilt motor 117 according to the input of the direction setting key (vertical, horizontal) from the touch screen and sets the launching direction of the practice ball launcher 105, and makes the cylinder 130 of the hydraulic device operate and launch the practice ball through the solenoid valve driving part (SOD) every set time period (e.g., every 15 seconds). In the case of the image pickup apparatus mode, the controller (MPU) controls the rotation motor 120 and the tilt motor 117 so that the practice ball emitter 105 is directed toward the player of the course photographed at the image pickup apparatus 1, 2(CAM1, CAM2), and then controls the operation of the practice ball launching apparatus 100 so that the cylinder 130 of the hydraulic device is operated by the solenoid valve driving part (SOD) and the practice ball is emitted after 1 to 2 seconds when the player moves with a movement set in advance (for example, when the player lifts the arm up).

Fig. 7 is an operation sequence diagram of the practice ball launching apparatus according to the embodiment of the present invention, which is used to explain operations in the case of the manual mode and the automatic mode. And, fig. 8 is an operation sequence diagram of a practice ball launching apparatus according to still another embodiment of the present invention, which sets a launching direction by means of image capturing devices 1, 2(CAM1, CAM2) provided at a side of a main body 102, senses movement of a player by means of the image capturing devices 1, 2(CAM1, CAM2) and launches a practice ball.

First, referring to fig. 6 and 7, the operation of the practice ball launching device 100 shown in fig. 1 to 5 will be explained.

As described above, the device 100 for launching a training ball includes a touch panel (TS) provided outside the main body 102, the touch panel (TS) being connected to a controller (MPU) provided inside the main body 102, and the controller (MPU) controlling the operations of the respective operation elements provided inside the main body 102 by data input through the touch panel (TS). In other words, the controller starts controlling the operations of the tilt motor 117 and the swing motor 120, the hydraulic pump 142, and the

various solenoid valves

146, 148, and 150 inside the main body 102.

The practice ball launching device 100 can be operated in a manual setting mode and a movement sensing mode by the control of the controller (MPU). In the manual setting mode, after setting a sport mode (any one of penalty ball, corner war tactics, ground ball shooting, shot ball, heading shot, service ball, or a mixture thereof) and a launch period (for example, launching a ball about every 15 seconds) using a Touch Screen (TS) provided in the main body 102, the user launches the practice ball to the field 10 every time the launch button is pressed, or selects one or more of the ground ball, the shot ball, the heading shot, and the service ball, or a mixture thereof, and presses the launch button, the launch angle (tilt and swivel motors 117, 120) of the hollow body 114 is adjusted according to the automatically selected sport mode, and the practice ball is continuously launched at a preset period. In this case, the example where the transmission button is located on the touch panel (TC) has been described, but it can be provided on a remote controller carried by a soccer player using a general remote control device.

[ Manual/automatic setting mode of the practice ball launching apparatus 100 ]

If the practice ball launching apparatus 100 is operated, the transmitter (MPU) detects the pressure in the nitrogen tank 144 in the process of S1, and retrieves whether it is the pressure that causes the piston 132 of the cylinder 130 to protrude (discharge) at a speed set in advance. When the pressure of the nitrogen pipe in the nitrogen tank 140 cannot reach the preset pressure, the controller opens the recovery and

supply solenoid valves

146 and 148 through the solenoid valve driving unit (SOD) in step S6, and then drives the hydraulic pump 142. Thus, the hydraulic pressure in the cylinder 130 is recovered to the hydraulic tank 140 and then supplied to the nitrogen tank 144. If the hydraulic pressure is continuously supplied to the nitrogen tank 144, the pressure applied to the nitrogen pipe provided inside thereof is increased and reaches the set pressure.

In the S2 process, the controller (MPU) closes the recovery/

discharge solenoid valves

146, 148, 150 by the solenoid valve driver (SOD) in the S3 process when the pressure of the nitrogen tank is determined to be the set pressure, detects whether the fire button of the touch panel or the remote controller is pressed in the S4 process, and opens the discharge solenoid valve 148 for a previously set time (T) in the S5 process when the fire button is determined to be pressed in the S4 process. At this time, the hydraulic pressure charged into the nitrogen tank 144 at a high pressure is supplied to the inflow port of the cylinder 130 through the discharge solenoid valve 148 at a high speed due to the expansion of the compressed nitrogen pipe.

Thus, the cylinder 130 protrudes the piston 132 located inside thereof in a forward direction by the hydraulic pressure flowing in at a very high pressure, and the striking plate 134 coupled to the end thereof by the forward protrusion of the piston 132 strikes the practice ball placed on the end of the hollow body 114 and is shot in a forward direction. At this time, the launch angle of the practice ball launcher 105 located in the space portion of the main body 102 of the practice ball launching apparatus 100 is determined by the controller controlling the tilt motor 117 and the spin motor 120.

The controller (MPU) performing the S5 process opens the recovery and

supply solenoid valves

146 and 148 through a solenoid valve driver (SOD) in S6, and then hydraulically fills the nitrogen tank 142 by driving the hydraulic pump 142 in S7.

If the launching button displayed on the Touch Screen (TS) is not selected during the aforementioned S4, the controller (MPU) performs the aforementioned S5 process after adjusting the horizontal, vertical angle and launching interval of the hollow body 114 of the practice ball launcher 105 according to the set mode during S8. The mode set in the process of S8 refers to setting of an automatic transmission mode and an image capturing device mode.

If the setting mode is the case of the automatic transmission mode in S8, the controller (MPU) drives the swing motor 120 and the tilt motor 117 by the input of the direction setting key (vertical, horizontal) from the touch screen and sets the transmission direction of the practice ball transmitter 105, operates the cylinder 130 of the hydraulic device through the solenoid valve driving part (SOD) at every previously set time period, and transmits the practice ball. Further, in the case where the setting mode is determined as the image pickup device mode in the process of S8, the controller (MPU) controls the operation of the training ball launching device 100 in the order of fig. 8, and in the case of the stop mode in the process of S8, does not perform any operation.

[ moving perception mode ]

In the movement sensing mode, after the launching direction is set by the image capturing devices 1, 2(CAM1, CAM2) provided at the side of the main body 102, the practice ball is launched by the image capturing devices 1, 2(CAM1, CAM2) according to the movement of the player located at the front or the side.

Referring to fig. 8, the controller (MPU) searches whether the current mode is the image pickup device mode in the process of S104. If the search result is not the case of the image pickup device operation mode, a jump is made to the process of S17 and the practice ball is launched according to the manual/automatic mode operation as previously described.

If it is determined that the image capturing device is operated in the S12 process, the controller (MPU) receives the image signals photographed by the image capturing devices 1 and 2(CAM1 and CAM2) provided at the side of the main body 102 in the S11 process, and detects the movement of the player positioned in front of or at the side of the practice ball launching device 100 in the S12 process. After the controller (MPU) that detects the movement of the player grasps the position where the detected player is located, the tilt motor 117 and the horizontal motor 120 are controlled to adjust the vertical angle and the horizontal angle in S13, thereby setting the launch angle of the practice ball launcher 105.

Then, the controller (MPU) analyzes the video signal transmitted from the image capturing apparatuses 1 and 2(CAM1 and CAM2) in S14, analyzes the movement of the subject, and searches whether the movement of the player is a movement set in advance in S15. For example, a search is made as to whether or not the player is in a state where his arm is lifted. The retrieval can be easily retrieved by comparing the frame image 1 second ago with the current frame image.

If it is determined in the process of S15 that the player' S movement of the video signal received by the image capturing devices 1 and 2(CAM1 and CAM2) is a movement set in advance, the controller (MPU) controls the solenoid driver (SOD) in the process of S16 such that the striking plate 134 provided in the front portion of the piston 132 of the cylinder 130 strikes the practice ball and the practice ball is shot toward the subject.

Depending on the operational mode of the launching of the practice ball launching apparatus 100, the launching port of the practice ball launcher 105 may be directed toward a portion where a practice ball launched toward a player flies or rolls into the sideline or goal line direction upon hitting the player's body (e.g., foot, hand, etc.) and finally falls on the ground of the court.

In the illustrated embodiment, a hydraulic cylinder is illustrated as the driver of the practice ball launcher 105, but a pneumatic cylinder may be used if it is a person of ordinary skill in the art understanding the present specification.

Fig. 9 is a concrete constitution of the ball retriever according to the embodiment of the present invention, showing a case of being provided on one side of the ground of the court 10. At this time, as described above, it should be understood that the court is a concept including a soccer field, a basketball field, a volleyball field, a footvolleyball field, and the like, which can perform ball games. In order to roll the practice ball dropped to the court 10 from a half-straight line (or a half-straight line) toward the goal line (or end line), it is formed obliquely (θ 2) from the center to both sides. As shown in fig. 3, the ball retriever 200 shown in fig. 9 is provided in the transfer trough 14, and the transfer trough 14 is formed at the rear portion of the goal line or the end line of the court 10.

The transfer groove 14 is formed to be inclined downward from one side corner to the other side corner or the center direction. Thus, the practice balls dropped to the court 10 inclined from the half-straight line (HL) or the half-straight line to the goal line or the end line on both sides roll in the goal line direction from the half-straight line (HL), and finally are gathered in the transfer groove 14. The practice balls collected in the transfer chute 14 roll toward the lower end of the ball recovery unit 200, which is a cylindrical collecting pipe, and the practice balls flowing toward the lower end of the ball recovery unit 200 flow into the lower end gate (G) of the ball recovery unit 200.

As shown in fig. 9, when the recovery motor 206 provided in the upper part of the ball recovery unit 200 rotates, the rotation shaft 208 connected thereto rotates. At this time, a screw-type screw 210 is formed on the outer peripheral surface of the rotary shaft 208, and the screw-type screw 210 has a pitch (pitch) about 1cm wider than the diameter of the practice ball (for example, 220 mm). At this time, the distance (r1) between the rotary shaft 208 and the inner surface of the ball recovery unit 200 is formed to be smaller than the diameter r2 of the practice ball by about 2mm to 3 mm. Thus, when the rotary shaft 208 is rotated, the practice ball flowing into the lower end gate G of the ball recovery unit 200 is transferred to the upper portion along the screw transfer 212, and the screw transfer 212 includes the rotary shaft 208 and the screw 210. At this time, the distance (r2) between the rotation axis 208 and the inner surface of the ball retriever 200 is formed smaller than the diameter (r1) of the practice ball, so that the practice ball is slightly deformed and thus smoothly transferred to the upper portion.

The vibration plate 214 that vibrates in the longitudinal direction by the rotation of the vibration motor 216 is fitted into the transfer groove 14 in the front portion of the door G of the ball recycler 200. The vibration motor 216 rotates simultaneously with the recovery motor 206 during the ball recovery operation, so that the practice balls gathered at the end of the downwardly inclined transfer chute 14 smoothly enter the door (G) direction of the ball recoverer 200.

The practice ball transferred to the upper portion of the screw transfer 212 of the ball retriever 200 is discharged to the ball discharge pipe 202 by the rotation of the screw 210. The practice ball discharged through the ball discharge tube 202 is configured to be put into the practice ball through the upper opening of the ball receptacle 104 of the practice ball launching device 100 disposed adjacent to the ball retriever 200, as shown in fig. 1 to 8.

In the above embodiment, the ball recovery unit 200 is configured such that the rotating shaft 208 of the screw 210 is provided inside the cylindrical collecting pipe 204 and is transferred to the upper portion along the inner walls of the screw 210 and the cylindrical collecting pipe 204, but a screw transfer device having an equivalent configuration can be applied.

For example, the following can be considered: two poles (pole) are provided in the direction of the gate into which the practice ball rolls from the rotation shaft 208 of the screw 210, and are vertically erected on both sides of a distance shorter by about 1mm to 2mm than the diameter r2 of the practice ball. When the practice ball rolls and flows into the door constituting the ball retrieving unit according to the other embodiment as described above, it is positioned between the rotation shaft 208 and the two rods, and when the screw type screw is rotated, the practice ball moves in the vertical direction along with the rotation shaft and the two rods, and is received into the practice ball launching device 100 through the upper opening of the ball receiver 104.

In the configuration of fig. 9 described above, the ball discharge pipe 202 provided at the upper portion of the ball recovery unit 200 may be designed as follows, as indicated by "R" in the drawing: the rotation mechanism is provided on the upper portion of the cylindrical collecting pipe 204 in a rotatable manner, and rotates the ring gear or the like manually or by a motor, thereby automatically rotating by power.

Fig. 10 is a detailed configuration diagram of a ball dispenser 300 according to the present invention, which is provided to a post 25 vertically erected on the ground of a court 10 so that a practice ball is dropped to the court 10 or the practice ball is flown in a horizontal direction to dispense a ball toward a player located on the court 10, usefully for a pinball of a footkick and volleyball, a tee shot of a basketball, and the like.

Referring to fig. 10, the ball dispenser 300 includes a housing 301 coupled to an upper side of the post 250. The housing 301 is opened at an upper side thereof, a ball reservoir 304 is formed in the housing, and the ball reservoir 304 is separated from the housing by a partition wall 308 to form a discharge space 306. The floor 305 of the ball storage 304 is formed to be inclined downward toward the discharge space 306, an opening is formed in the floor of the discharge space 306, and a discharge pipe 316 for discharging the practice balls is rotatably coupled to the opening.

A stopper (stopper)314 is vertically provided on one side of a discharge opening formed in the lower surface of the discharge space 306, and the rotary opening/closing plate 310 is screwed to the rotary shaft of the opening/closing motor 302 fixed to one side of the inside of the casing 301 at the partition wall 308. The rotary opening/closing plate 310 opens and closes a discharge hole formed in the lower portion of the partition wall 308 by the rotation of the opening/closing motor 302, and the practice ball stored in the ball storage space 304 is discharged through the discharge hole.

An upper end portion of the discharge pipe 316 is inserted into an installation space provided below the housing 302, and a rack of a straight bevel gear (below gear)318 is coupled around the discharge pipe. The driving gear of the linear bevel gear 318 is coupled to a rotating shaft 322 of a swing motor 320 fixed to the installation space, and is connected to the opening and closing motor 302, the swing motor 320, and a controller (MCU) 324. The drain pipe 316 is formed to be inclined downward, a vertical drop outlet 316a and a horizontal outlet 316b are formed at the end portions thereof, the vertical drop outlet 316a is formed to be directed downward, the horizontal outlet 316 is formed to be inclined in the horizontal direction, and the balls flowing into the drain pipe 316 are discharged to the vertical drop outlet 316a and the horizontal outlet 316b through a damper 316c coupled between the drop outlet 316a and the horizontal outlet 316 b.

The damper 316c opens either one of the vertical drop outlet 316a and the horizontal outlet 316b by a damper driver 316d composed of a motor or the like. In the case where the damper driver 316d is not used, a general manual damper (shutter) that is manually operated may be used. In the case of using the damping driver 316d, the damping driver 316d is controlled by the controller 324 receiving a remote control signal of the remote controller.

For example, when the damper driver 316d drives the damper 316c in the vertical direction, the vertical drop outlet 316a is opened and the horizontal outlet 316b is closed, so that the practice ball discharged from the discharge pipe 316 falls straight downward. On the contrary, when the damper actuator 316d drives the damper 316c in the horizontal direction, the drop outlet 316a is closed and the horizontal outlet 316b is opened, so that the practice ball discharged from the discharge pipe 316 is dropped while flying in the horizontal direction through the horizontal outlet 316 b.

When the opening and closing motor 302 is rotated once by the control of the controller 324 shown in fig. 10, the rotary opening and closing plate 310, which is coupled to the rotary shaft 312 of the opening and closing motor 302, is opened and closed, and one exercise ball is directly dropped from the upper part of the ground (court) of the court 10 through the vertical drop outlet 316a provided at the end of the discharge pipe 316, or is dropped to the ground (court) of the court 10 after flying in the horizontal direction through the horizontal outlet 316b, so that the player can perform an exercise of hitting a ball dropped from the upper side in a plurality of directions or catching the passed exercise ball and shooting. Thus, the player can perform a variety of exercises as follows: the practice ball dropped vertically from the upper portion of the ground of the field 10 (field) or uploaded in the horizontal direction is subjected to a catching attack practice struck with a strong hand or to a shooting with a foot.

Further, the direction of the end of the discharge pipe 316 is adjusted by the rotation of the swing motor 320, and the falling direction of the ball can be adjusted, so that the practice can be performed at a plurality of positions.

The controller 324 receives and transmits data to and from the controller 324 of the practice ball launching apparatus 100 by wire or wirelessly, and receives input of a ball distribution control signal, thereby controlling the opening and closing motor 302 and the swing motor 320, or controlling the same by a remote controller alone. In the case of control with a remote controller alone, the controller 324 drives the opening and closing motor 302 and the swing motor 320 by a remote control signal transmitted from the remote controller, and can drop the practice ball accommodated in the ball storage 304 onto the ground (field) of the court 10.

The practice ball launching device 100, the ball retriever 200, and the ball dispenser 300 configured as described above may be applied to ball game items, such as soccer, volleyball, and basketball, where the court is set, appropriately selected according to the respective ball game items. Fig. 11, 16, 17 and 18 below show examples of a soccer practice device, a foot volleyball practice device, a volleyball practice device, and a basketball practice device.

Embodiments of a soccer practice device

Referring to fig. 11 to 15, the soccer practice apparatus 1 according to the preferred embodiment of the present invention includes a court 10 provided in a prescribed width. As shown in fig. 1 and 3, in the corner ball region of the goal line of the court 10, a practice ball launching device 100 and a ball retriever 200 are provided in two groups at the end portion of the court 10 in the diagonal direction, the practice ball launching device 100 launches a practice ball to the court 10, and the ball retriever 200 automatically collects the practice balls gathered in the direction of the goal line and supplies the practice balls to the practice ball launching device 100. On both sides of the pitch 10, goal lines are provided with conventional goal posts 12 arranged at the soccer field.

As shown in fig. 12, the pitch 10 shown in fig. 11 is formed to slope downwardly from the half-line (HL) to goal lines on both sides by 1 to 5 degrees. A transfer trough (transfer flow) 14 inclined downward from one side corner to the other side corner is formed at the goal line, more specifically, at the rear side of the gate post 12, so that the practice balls dropped on the floor of the court 10 roll along the inclined surface to the goal line and flow into the transfer trough 14, and the practice balls flowing into the transfer trough 14 are gathered along the inclined surface of the transfer trough 14 in the direction of the gate G of the ball retriever 200 provided at the corner.

To utilize the soccer practice apparatus 1 constructed as shown in fig. 11, one of the practice ball launching devices 100 provided on both sides of the court 10 is activated. The activation may be performed with a remote control carried by the player. The operation mode of the practice ball launching apparatus 100 activated by the remote controller is set to the "manual/automatic setting mode" or the "movement sensing mode", and the practice ball launching apparatus 100 launches the practice ball to the player as described above. Thus, the player of the court 10 can shoot or overhead the practice ball shot from the practice ball launching apparatus 100 in the form of a penalty kick, a corner kick, a groundball shot, a heading shot. At this time, the ball launched from the practice ball launching apparatus 10 is kicked or shot toward the gate post 12 by the player, and the practice ball enters the gate post 12.

The present invention includes the technical construction of sensing entry of a practice ball into the goal post 12 and scoring it.

As shown in fig. 14, a Ball Sensing Gate (BSG) is provided in front of or behind the gate post 12. Preferably, a Ball Sensing Gate (BSG) is provided behind the doorpost 12. The ball-sensing gate (BSG) is formed of a pipe material like the doorpost 12, and is disposed behind the doorpost 12 in a rectangular frame shape. A plurality of light emitting element (light emitting diode, infrared light emitting diode, etc.) arrays are disposed at regular intervals on the upper and left sides of a Ball Sensing Gate (BSG) having a rectangular frame shape, and light receiving element (e.g., infrared photodiode, phototransistor, etc.) arrays are disposed at the same interval on the lower and right sides of the Ball Sensing Gate (BSG).

The Ball Sensing Gate (BSG) is for sensing which part (area) of the doorpost 12 is passed through when a ball is practised to pass through the doorpost 12, and the configuration will be more clearly understood from the description to be described later. In addition, a Speed measuring Gun (SG) for measuring the Speed of the practice ball flying toward the gate post 12 is provided behind the Ball Sensing Gate (BSG).

The soccer practice apparatus 1 according to the embodiment of the present invention exemplifies soccer in which a plurality of persons can play together, but a five-player soccer game in a room may be directly applicable as well as a five-player soccer (futsal). For example, a football exercise and a five-player football game may be used alternately, and the positions of the goal posts 12 provided on the field 10 may be varied depending on the football or five-player football game. For example, it is contemplated to provide movable wheels or the like under the doorpost 12. In other words, the soccer field of five persons in which a field can be easily constructed indoors is provided with the soccer practice device 1 of five persons, which is commonly used, and then the use of the soccer field, which is used for an individual or a plurality of persons to practice soccer, can be easily changed, and for this reason, it is preferable to freely move the doorpost 12.

[ conversion mode of goal score of soccer when practice ball passes through goal post ]

In the case where the practice ball passes through the gate post 12 shown in fig. 11, the sensor of the Ball Sensing Gate (BSG) shown in fig. 13 senses the ball. Each sensor of the Ball Sensor Gate (BSG) includes light emitting element arrays XL1 to XL4, YL1 to YL10, and light receiving element arrays XP1 to XP4, YP1 to YP10 provided in opposite directions correspondingly thereto.

Fig. 13 is a view showing an example of a Ball Sensing Gate (BSG) which divides a soccer goal post into 40 areas and determines scores for the different areas, the respective areas being used to sense the passage of a practice ball. The Arabic numerals "0 to 10" marked inside the Ball Sensor Gate (BSG) in FIG. 13 represent scores of different regions.

Referring to fig. 13, the ball induction door (BSG) coupled to the rear of the gate post 12 is shown in which light emitting device arrays XL1 to XL4 and YL1 to YL10 are provided on the left and upper sides of the ball induction door (BSG), and light receiving device arrays XP1 to XP4 and YP1 to YP10 are provided on the right and lower sides of the ball induction door (BSG). At this time, the light emitting device arrays XL1 to XL4 and the light receiving device arrays XP1 to XP4 provided on the left and right sides of the ball induction door (BSG) in a rectangular frame shape are shown to divide the height (2440mm) of the soccer goal post 12 into 4 equal parts and to be provided at a pitch of 610mm, and the light receiving device arrays XP1 to XP4 and YP1 to YP10 provided on the upper and lower sides of the ball induction door (BSG) divide the lateral length (7320mm) of the soccer goal post 12 into 10 equal parts and to be provided at a pitch of 732 mm.

At least 3 light emitting elements are arranged at equal intervals inside the light emitting element arrays XL1 to XL4 and YL1 to YL10, and at least 3 light receiving elements are also arranged at equal intervals inside the light receiving element arrays XP1 to XP4 and YP1 to YP10 which are arranged in the opposite direction corresponding to the light emitting element arrays XL1 to XL4 and YL1 to YL 10. The light emitting element arrays XL 1-XL 4 and YL 1-YL 10 which are formed as described above respectively obtain light emitting drive according to X-axis and Y-axis drive signals, and the light receiving element arrays XP 1-XP 4 and YP 1-YP 10 sense light sources of the light emitting element arrays XL 1-XL 4 and YL 1-YL 10.

In the above embodiment, it has been described that 3 elements are provided inside the light emitting element arrays XL1 to XL4, YL1 to YL10 and the light receiving element arrays XP1 to XP4, YP1 to YP10, but it is obvious that a larger number may be provided in order to improve sensitivity.

Fig. 14 shows a structure of a Scorer (SCNT) which drives light emitting element arrays XL1 to XL4 and YL1 to YL10 of a Ball Sensing Gate (BSG) shown in fig. 13, reads outputs of light receiving element arrays XP1 to XP4 and YP1 to YP10, senses which part of a gate post 12 an exercise ball passes through, and converts and displays a score according to the ball speed of the exercise ball sensed by a Speed Gun (SG).

Referring to fig. 14, the Scorer (SCNT) includes: light emission driving units LD1 and LD2 that drive light emitting element arrays XLi and YLj (here, i is "1 to 4" and j is an integer of "1 to 10") provided in the X axis and the Y axis of a Ball Sense Gate (BSG) by light emission control signals; light receivers PR1, PR2 provided opposite to the light emitting element arrays XLi, YLj of the X-axis and Y-axis of the Ball Sense Gate (BSG) to read outputs of the light receiving element arrays XPi, YPj that receive the light sources (or infrared rays) irradiated from the light emitting element arrays XLi, YLj; a Score Controller (SCNT) that illuminates the light emitting element arrays XLi and YLj provided on the X-axis and Y-axis of the Ball Sensing Gate (BSG) by driving the light emitting driving units LD1 and LD2, determines a ball passing region of the gate post 12 from signals output from the light receivers PR1 and PR2, and converts a score using an Impact signal output from an Impact Sensor (IS) and an output from a Speed Gun (SG) provided behind the gate post 12, the light receivers PR1 and PR2 reading outputs from the light receiving element arrays XPi and YPj provided on the X-axis and Y-axis of the Ball Sensing Gate (BSG), the Impact Sensor (IS) being provided on the gate post 12 or the Ball Sensing Gate (BSG); and a Display (DISP) for displaying the score converted by the Score Controller (SCNT) to the outside. In the embodiment of the present invention, although the description has been given of the case where the light-emission driving sections LD1, LD2 and the light-receiving devices PR1, PR2 are included, in the case where the fraction controller (SCNT) directly drives the light-emitting element arrays XLi, YLj and directly reads the outputs of the light-receiving element arrays XPi, YPj, it may not be included.

The operation of the score conversion when the practice ball passes through the gate post will be described with reference to fig. 13 and 14.

When the soccer practice device 1 is operated, the Score Controller (SCNT) shown in fig. 14 supplies light emission control signals to the light emission driving units LD1 and LD2, so that the light emitting element arrays XLi and YLj provided on the X axis and the Y axis of the ball induction gate (BSG) shown in fig. 13 are both lighted. At this time, all the light emitting elements in the light emitting element arrays XLi, YLj disposed on the left and upper portions of the X and Y axes are lighted, and light generated by the lighting illuminates the light receiving element arrays XPi, YPj disposed correspondingly on the right and lower portions of the X and Y axes, respectively. At this time, the light receiving element arrays XPi, YPj receive (sense) light illuminating the light emitting element arrays XLi, YLj, and cause respective sense signals to be input to the light receivers PR1, PR 2.

Since the ball is not normally in the state of entering the gate post 12, the light illuminated from the light emitting element arrays XLi, YLj disposed on the left side of the X axis and the upper portion of the Y axis is supplied to the light receiving element arrays XPi, YPj in a state of not being cut off. Thus, in the case where the ball does not enter the gate post 12, the signals sensed at the light receiving element arrays XPi, YPj are all the same, and the sensed signals are supplied to the fraction controller (SCNT) through the light receivers PR1, PR 2.

The Score Controller (SCNT) senses whether or not the ball is cut off by using the sensing signals of the light receiving arrays XLi and YLj received through the light receivers PR1 and PR2, thereby discriminating which region of the gate post 12 the ball passes through. In the case where the ball does not pass through the gate post 12, the sensing signals of the light-receiving element arrays XPi, YPj both remain in the activated (logic "high") state, and hence the goal is not considered.

In the case where the practicing ball shot by the exerciser passes through the "a" region of fig. 13, the light illuminated from the light emitting element arrays XL1, YL1 is momentarily cut off by the practicing ball passing through the "a" region, thereby producing a state where the outputs of only the two light receiving element arrays XP1, YP1 are momentarily inactive (logic "low"), which is immediately supplied to the Score Controller (SCNT) through the light receivers PR1, PR 2. At this time, the Score Controller (SCNT) senses that the outputs of the two light-receiving element arrays XP1, YP1 are in an inactive state, recognizes that the practice ball passes through the "a" region of fig. 13, and gives a score of "10" according to the score content of the program (program).

Then, the Score Controller (SCNT) reads the speed information of the practice ball sensed by the speed measuring gun (SG) provided behind the gate post 12, gives a weighted value according to the speed information to the gate post passing score "10", determines the gate post passing score, and displays the practice ball passing area and the gate post passing score by the Display (DISP), so that the practitioner can confirm which part the ball kicked by himself enters. Thus, the exerciser can take more interest to exercise. The weighting value is 1 when the ball velocity is equal to or higher than the impact (60 Km/h per hour), and 0.5 when the ball velocity is equal to or lower than the impact, so that the scores are different depending on the ball velocity even when the ball passes through the same region.

If a trainee shoots a ball after passing through the 'A' area and the 'B' area of the Ball Sensing Gate (BSG) and then takes the ball, the average value of the two areas is determined as a gate post passing score, a weighted value according to the speed sensed at the speed measuring gun (SG) is given, and the gate post passing score is displayed on the Display (DISP). In addition, when the impact sensing sensor (IS) provided in the gate post 12 senses the impact in the state that the practice ball IS hit into the passing area of the Ball Sensing Gate (BSG), the Score Controller (SCNT) scores the gate post passing score as "10" regardless of the passing area of the practice ball and displays the score.

As described above, the soccer practice apparatus according to the present invention senses the passing area of the doorpost and the speed of the ball when the practitioner shoots a goal toward the doorpost, and displays the passing area of the doorpost and the passing score of the doorpost on the display, so that the practitioner can practice with more interest, and can easily confirm which area the ball shot by the practitioner passes, thereby correcting the shooting posture, etc. more quickly.

Although not specifically illustrated in the embodiment, infrared or optical sensors are provided at intervals of the diameter of the ball in the vertical and horizontal directions of the gate post 12, so that it is possible to sense the place where the practice ball passes through the gate post 12 and give points according to the different areas where the practice ball passes through the gate post 12, thereby enabling the player to confirm the point of shooting by himself. For example, the score is displayed by setting the score passing near the four corners of the doorpost 12 to 10 points and gradually decreasing toward the center of the doorpost 12.

Embodiments of a foot volleyball exercise device

The volleyball is a ball game in which two teams win or lose a ball by passing the ball to each other through a net and using a head and feet, and is intended to effectively practice catching (receiving) a practice ball flown from an opposite field by serving (serve), striking a practice ball dropped downward from a position higher than the net, and transmitting the ball to an opposite field (strike).

To this end, as shown in fig. 16, the foot volleyball exercise device 1 according to the preferred embodiment of the present invention includes a court 10 in which a standardized field is drawn with an end line, a side line, and a half-line. Three practice ball launching devices 100(G1, G2) for launching practice balls toward the field of the court 10 are provided at corner portions where the end line and the sideline of the court 10 meet. Further, ball retrievers 200 are provided at corners of the court 10, and the ball retrievers 200 automatically collect the practice balls gathered in the end line direction and supply them to the practice ball launching devices 100. At any one portion near the borderline or the end borderline of the footlet court 10, preferably, at a portion adjacent to a NET Post (POL) provided with a NET (NET), a ball dispenser 300 is provided, the ball dispenser 300 causing balls stored in a ball storage 304 to fall down to the field of the court 10 through a lower dispensing pipe 316. Although an example in which the ball dispenser 300 is disposed adjacent to the side line drawn on the footlet court 10 is given in the embodiment, the location of the ball dispenser 300 is not limited thereto, and it should be recognized that it may be disposed in various places.

The ball dispenser 300 may be provided to be hung on a pipe or the like provided in a lateral or longitudinal direction from an upper portion of the court 10, but in the embodiment of the present invention, an example in which the ball dispenser is provided on one side of an upper portion of the pillar 250 is described. An image capture device (CAM) for capturing a forward subject is provided in front of the practice ball launching device 100(G1, G2).

As described above, one end portion of the ball transfer line 251 is located adjacent to the portion where the end portion of the ball discharge pipe 202 of the ball retriever 200 is located, and the other end portion of the ball transfer line 251 is disposed toward the opening of the ball storage 304 of the ball dispenser 300. At this time, one end of the ball transfer line 521 is positioned higher than the other end. For example, the ball is inclined downward so that the ball is naturally transferred toward the other end by its own weight when the practice ball is placed on the one end. A NET (NET) is transversely arranged at the central part of the volleyball court 10.

As shown in fig. 12, the field 10 shown in fig. 16 is formed obliquely downward from the half-straight line (HL) to the end lines on both sides. At this time, the downward inclination angle may be set to 1 to 5 degrees. Specifically, a transfer trough (transfer trough) 14 inclined downward from one side corner to the other side corner is formed at the rear edge of the end line, so that the practice ball dropped on the floor of the footlet field 10 rolls along the inclined surface to the end line and flows into the transfer trough 14, and the practice ball flowing into the transfer trough 14 is collected along the inclined surface of the transfer trough 14 in the direction of the door G of the ball retriever 200 installed at the corner and is retrieved.

Although not specifically shown in the drawings for illustrating the embodiment of the present invention, the practice ball launching device (G1, G2) shown in fig. 1 further includes a ball receiver 104. The practice ball can be manually put into the ball container 104 of the practice ball launching device (G1, G2) provided at the side corner portion, or the aforementioned ball retriever 200 can be used.

[ ball catching in foot volleyball ]

The practice ball launching devices 100, G1, G2 provided at the course 10 of the footlet practice apparatus 2 according to the embodiment of the present invention are also as explained in the soccer practice apparatus 1, and only at least one is activated by the remote controller. The operation mode of the practice ball launching apparatus 100, G1, G2 activated by the remote controller is set to the "manual/automatic setting mode" or the "movement sensing mode", and the practice ball launching apparatus 100 launches the practice ball toward the player located on the other field floor of the NET (NET) of the field 10 as described above. At this time, the player catches the ball launched from the practice ball launching apparatus 10 with his foot or head, etc. and passes over the NET (NET), thereby performing a foot volleyball catching practice.

With the foot volleyball exercise device 2 according to the embodiment of the present invention, the ball dispenser 200 illustrated in fig. 10 is provided to the sideline portion of the court 10 as shown in fig. 1.

[ foot volleyball smash mode ]

The teeing mode of the volleyball practice device 2 is also set through a Touch Screen (TS) remote controller provided to the main body 102 of the practice ball launching device 100.

When the ball-attaching mode is set by the key buttons of the Touch Screen (TS), the control unit MPU shown in fig. 6 transmits corresponding information to the controller 324 in the ball dispenser 300 shown in fig. 10. Data transmission and reception between the control unit (MPU) of fig. 6 and the controller 324 in the ball dispenser 300 may be wired or wireless, and a pinball dispensing control signal generated from image information photographed by an image pickup device (CAM) may be transmitted. For example, in a state where the operation mode is the ball-catching mode, when a movement predetermined by the exerciser (for example, as if the arm is lifted) is detected by the image capture device (CAM) or a ball-catching signal is received from a remote controller carried by the user, a ball-dispensing control signal is transmitted to the controller 324 of the ball dispenser 300.

If the user sets the ball-catching mode using the remote controller, the ball dispenser 300 is driven. If the ball dispenser 300 is driven, the practice balls, as previously described and illustrated in fig. 10, are discharged from the vertical drop outlet 316a or the horizontal outlet 316b of the distribution duct 316 of the ball dispenser 300, so that the practice balls dropped vertically or horizontally from the upper portion of the court 10 are dropped on the upper surface of the court 10, so that the players can practice hitting the pinball of the practice balls dropped from the upper portion to the lower portion or dropped in the horizontal direction.

As described above, the ball game exercising device of the present invention serves a ball at the end line of the footlet field, and allows the ball to vertically fall or fly and fall along the horizontal line at the upper portion adjacent to the side line, so that the footlet exerciser can more effectively perform the ball-catching action and the ball-catching exercise.

When the discharge port of the ball discharge tube 202 is positioned above the ball transfer line 251, the recovered practice balls discharged therefrom are stored in the ball storage 304 along the inclined ball transfer line 251 through the upper opening of the ball dispenser 300.

Embodiments of volleyball practice device

Volleyball is a ball game in which two teams pass a ball to each other through a net by arms and hands and win or lose the ball, and a shot attack (strike) in which a shot is taken (serve) from a shot passed from an opposite field and the shot dropped from top to bottom is kicked down should be effectively practiced.

For this reason, the volleyball practice apparatus 3 according to the embodiment of the present invention is provided to the court 10 provided as shown in fig. 17. A practice ball launching device 100 for launching a practice ball toward the court 10 is provided at a portion of a corner area where an end line and a sideline of the court 10 meet. Further, a ball retriever 200 is provided, and the ball retriever 200 automatically collects the practice balls gathered to the end line and supplies the practice ball launching device 100. Further, with the volleyball practice apparatus 3 according to the present invention, a practice ball launching apparatus 100a having the same configuration as the practice ball launching apparatus 100 is provided on the sideline side of the court 10. At this time, the practice ball supply of the practice ball launching apparatus 100a is manually performed. Of course, the same structure as the ball retriever 200 may be provided adjacent to the practice ball launching device 100a to automatically feed the balls, or the ball transfer line may be provided between the ball discharge tube 202 provided in the ball retriever 200 and the ball storage provided above the practice ball launching device 100a to automatically feed the balls.

Any one of the parts of the court 10 near the sidelines, for example adjacent to the NET Post (POL) on which the NET (NET) is provided, is provided with a ball dispenser 300 which drops the balls stored in the upper ball store 304 through a lower dispensing duct 316 to the inside of the court 10. In this case, the ball dispenser 300 may be provided to be hung on a pipe or the like provided in a lateral or longitudinal direction from the upper portion of the court 10, but in the embodiment of the present invention, an example in which the ball dispenser is provided on one side of the upper portion of the pillar 250 is described. An image pickup device (CAM) for picking up a forward shot is provided in front of the practice ball launching device 100 and the practice ball launching device 100a provided on the sideline side.

The post 250 is mounted on the upper portion of a guide rail 252 which is provided in spaced relation parallel to the edge of the pitch 10 so as to be movable in a fore and aft direction along the edge of the pitch 10. At this time, the upper end of the post 250 is formed higher than the height of a net post (net POL) (POL) provided in the court 10, and a roller 251 mounted on the guide rail 252 is attached to the bottom surface, thereby sliding in the front-rear direction on the upper portion of the guide rail 252. Of course, the fixing means is coupled to the roller 251 so as to be fixed in a manner of preventing movement in the guide 252.

Thus, the ball dispenser 300 is coupled to the upper column 250, moves on the upper portion of the rail 252, and can approach the ball discharge pipe 202 provided in the ball retrieving unit 200. At this time, when the ball discharge tube 202 of the ball retriever 200 is rotated toward the upper portion of the ball dispenser 300, the practice balls supplied from the ball retriever 200 enter the ball storage 304 of the ball dispenser 300.

[ volleyball catching and catching mode ]

The volleyball practice apparatus 3 according to an embodiment of the present invention is similar in construction and operation to the foot volleyball practice apparatus 2. For example, when a ball is returned from the opponent's field to the field where the player is located, the operation of the ball catching exercise is the same as the ball catching mode of the foot volleyball exercise device 2. In addition, the ball catching mode for volleyball practice is directly applicable to the manual/automatic setting mode and the movement sensing mode of the practice ball launching device 100 described above.

As shown in fig. 17, the pinball mode is also such that the ball dispenser 300 shown in fig. 10 flies in the horizontal direction or falls in the vertical direction from the upper part of the sideline of the court 10. At this time, the player located on the field of the field 10 can practice hitting a pinball of a practice ball dropped vertically from above or dropped horizontally.

As described above, the volleyball training device of the present invention serves a ball at the end line of a volleyball court, and allows the ball to fall down at the upper portion of the side line adjacent to the court, so that a volleyball trainee can more effectively perform the training of a ball-catching action and a ball-catching action.

[ supply of balls to ball dispenser ]

When the practice balls stored in the ball storage 304 of the ball dispenser 300 are not present, the column 250 is pushed toward the ball retrieving unit 200 of fig. 1, and the column 250 coupled to the upper portion of the track 252 is moved in the front-rear direction along the track 252 by the roller 251 coupled to the bottom surface. After the ball dispenser 300 is positioned at the lower portion of the ball discharge pipe 202 of the ball recoverer 200 by the operation as described above, the discharge direction of the ball discharge pipe 202 of the ball recoverer 200 is directed toward the upper opening direction of the ball reservoir 304 formed at the upper portion of the ball dispenser 300. In the above-described state, when the previously described ball retriever 200 is operated to retrieve the practice balls accumulated in the transfer chute 14 and discharge the practice balls to the upper pipe 316, the retrieved practice balls are put into the ball storage 304 of the ball dispenser 300.

Embodiments of basketball practice apparatus

Basketball is a sport in which two teams each consisting of 5 players hit the opponent's basketball (goal post) through passing or dribbling to compete scores, and a trainee shoots a practice ball in the form of passing to a basketball court or drops the ball in a three-score shooting area, so that the trainee should practice three-score shooting, etc.

For the operation as described above, the basketball practicing device 4 according to the present invention is provided to the court 10 which is provided as shown in fig. 18. As shown in fig. 19, the court 10 is formed to be inclined downward at a certain inclination angle (θ) from a half-straight line (HL) to an end line, and a transfer groove 14, in which a basketball practice ball rolled to the end line is guided, is formed behind the end line.

The transfer groove 14 is formed to be inclined downward from a side line to a central portion of the basketball court 10 of the basketball court, and a ball retriever 200 is provided at a lowermost portion of the transfer groove 14, and the ball retriever 200 is used to transfer the practice balls gathered in the transfer groove 14 to an upper portion. In addition, a basketball stand (BG) is provided near the end line of the basketball court 10 as in a general basketball court, so that a basketball is provided.

As shown in fig. 9, the ball retriever 200 shown in fig. 19 has a cylindrical shape such that the practice balls gathered at the entrance of the lower portion are transferred to the upper portion and supplied to the practice ball input opening of the practice ball launching device 100 coupled to one side of the upper end. The practice ball launching apparatus 100 includes a ball container 104 and is located at the rear of the basketball stand (BG), and the ball container 104 stores practice balls (training balls) supplied from the ball retriever 200. In the embodiment of the present invention, an example of the ball recovery unit 200 is shown.

In addition, the basketball practicing device 4 according to the present invention is provided with a ball dispenser 300 at a portion adjacent to the practice ball launching device 100 provided at the end line, i.e., at a side of the ball retriever 200 provided at the end line portion. The ball dispenser 300 drops the balls stored in the ball storage 304 provided at the upper portion to the triple ball shooting area through the discharge pipe 316 provided at the lower portion, and may dispense the balls in a state of dropping to the lower portion of the discharge pipe 316 or flying through the inclined end portion of the discharge pipe 316. Although the example of the ball dispenser 300 being positioned near the end line drawn on the basketball court 10 is shown in the embodiment of the present invention, the location of the ball dispenser 300 is not limited thereto, and it should be appreciated that it may be positioned at various places such as outside the side line.

The practice ball launching apparatus 100 of the basketball practice apparatus 4 constructed as described above is operated in the manual/automatic setting mode and the movement sensing mode as described above. The three-part ball shooting mode of action or the ball catching action of the practice ball flying from the air operated by the ball dispenser 300 is almost the same as the catching mode of the volleyball practice device 3.

In other words, when the opening and closing motor 302 is rotated once by the control of the controller 324 shown in fig. 10, the rotary opening and closing plate 310, which is coupled to the rotary shaft 312 of the opening and closing motor 302, is opened and then closed, and one practice ball is dropped directly from the upper portion of the three-ball shooting area of the court 10 through the drop outlet 316a provided at the end of the discharge pipe 316, or is flown in the horizontal direction through the horizontal outlet 316b and then dropped, so that the practice of shooting the practice ball can be performed in the three-ball shooting area of the court. At this time, the trainee catches the practice ball falling vertically downward from the upper portion of the field or flying from the horizontal direction with a hand and shoots the ball toward the basketball stand (BG), thereby practicing a three-minute ball shooting, etc. Further, the falling direction of the discharge pipe 316 can be adjusted by the rotation of the swing motor 320.

The controller 324 receives and transmits data to and from the controller 324 of the practice ball launching apparatus 100 by wire or wirelessly, and receives input of a ball distribution control signal, thereby controlling the opening and closing motor 302 and the swing motor 320, or controlling the same by a remote controller alone. In the case of control by a remote controller alone, the controller 324 drives the opening and closing motor 302 and the swing motor 320 by a remote control signal transmitted from the remote controller, and can drop the practice ball accommodated in the ball storage 304 to the tee shot area of the field 10.

The supply of the practice balls to the ball dispenser 300 is performed by rotating the upper end of the ball discharge tube 202 provided adjacent to the upper end of the disposed ball recoverer 200 toward the upper end opening of the ball dispenser 300.

As described above, the basketball practicing device of the present invention can deliver a ball toward a basketball court and supply the ball to various areas including a three-minute-ball-shooting area, so that a basketball exerciser can receive practice balls supplied from various locations and practice various shots including three-minute-ball shooting, and can automatically supply a ball dropped on the ground to the practice ball delivering device 100 and the ball dispenser 300, thereby performing basketball practice more efficiently.
