The present invention relates to a robot assembly for a sub serving a table tennis ball, and more particularly, a dual nut that is collapsible and movable and that catches the ball returned from the robot to be supplied to the sub robot for reuse. (Dual net) relates to a sub-robot assembly having a feature.

Ping-pong is a popular, competitive recreational sport. In a table tennis game, players play, return, and hand over a table tennis ball on each side of the table. There are often times when one would like to play a table tennis game alone without an opponent, and a variety of table tennis ball subsystems or robots have been developed to meet this. The devices serve the ball to the player, who can hit the ball in the direction of the robot and return it. However, the conventional apparatus lacks a functionally useful or effective means for catching the ball returned by the player and recycling it back to the sub robot.

For example, US Pat. No. 2,087,575 (Littell et al.) Relates to a device for discharging lightweight ping pong balls, which is a conveyor system with a mechanically mounted ball carrying member for moving in a continuous loop. overhead feed means in the form of a typical overhead hopper by means of a conveyor system.

US Pat. No. 2,508,461 (Lemon) discloses a table tennis ball discharge device, where the air is sucked in and compressed from the induction pipe, as in a household vacuum cleaner. A gravimetric feed collection box is provided for bringing the ball into the bottom of the guide tube. Lemon's device does not control the introduction of the ball, so when a large number of balls are introduced into the system, if the balls are not properly supplied, eventually air compression occurs.

U. S. Patent No. 3,917, 265 (Schrier) relates to another air bed ejector for loading balls into the discharge means and discharging the balls, including air means for transporting the balls from the collector. Here too, maintaining air compression becomes a problem. In addition, the apparatus does not disclose an effective means of catching the returned ball and feeding it to the discharge mechanism.

U.S. Patent No. 4,116,438 (Berliner) includes mechanical drawing means comprising two resilient and thin drawing discs extending generally parallel to each other and catching ping pong balls between the discs and ejecting them along the guides. Provided is an apparatus for throwing a table tennis ball. Here the ball is returned to the sub disc by air means.

U.S. Patent No. 2,793,636 discloses a pan operating device as disclosed in U.S. Patent No. 3,911,888 (Horvath).

U.S. Patent No. 3,989,242 (Augustine) discloses an enclosure means comprising a device for discharging a conventional ping pong ball and a net for catching the player's sub-ball.

U. S. Patent No. 3,794, 001 to Newgarden discloses a relatively simple device that informs a change in the amount of spin applied to a served ball.

I am also the co-inventor of U.S. Patent Nos. 4,844,458, 4,854,588, 4,917,380 and 5,009,421, all of which disclose a mobile table tennis sub device, including a sub-robot and a muzzle net. The device uses a single folding net associated with the robot to automatically feed the returned balls to the robot. A folding net structure is also provided for attaching to the table tennis table and for supplying the ball to the sub robot. The single net structure has a plurality of arms that extend from the central member and have nets between the arms. The net has a lower edge associated with the ball collecting device receiving the falling ball. The ball collecting box is for supplying the ball to the sub robot device.

In most cases, the preceding robot subdevice does not initiate the muzzle mechanism. A ping pong ball subassembly comprising a muzzle net typically has a single net where the ball hits the net and falls into the ball collector so that the ball can be resupplied to the robot.

Such prior art muzzle assemblies have disadvantages, first of all, a standard single net structure. The net hangs behind the sub-robot. When the serving robot device serves the ball, the player may hit the ball from the net and send it. However, the ball returned by striking a single net at high speed may bounce behind the net or fall from the net to the floor. In this respect, a single net configuration of the prior art is more convenient than no muzzle net at all. However, it is not effective to stop all throws to catch the ball and then feed it back to the sub robot. In addition, the sub-robot is installed toward the front of the device, protruding out of the net and dangerously close to the table. As a result, the ball often hits an exposed robot and bounces out of play. The robot can also invade the space required for the game.

The robot works best when the diameter of the ball is suitable and almost completely round. Incorrectly shaped or incorrectly sized balls can cause robot wear or malfunction and cause excessive wear. The preceding robotic assembly does not include means for removing the inappropriate ball prior to loading the ball.

In addition, conventional nets, even if they can be folded or folded, have not been fully folded to facilitate movement. Even if folded, the net extended outward from the base of the robot, making it inconvenient for storage. Prior art assemblies are difficult to attach to a table and the mechanism is complex. In addition, they are not easy to store and move and lack effective means for uniting the components of the assembly as well as the ping pong balls used in the assembly.

It is therefore a first object of the present invention to provide a ping pong ball subassembly having two nets that strike the assembly and drop the ball to the return mechanism in order to shoot the ball completely.

It is a second object of the present invention to provide a robot subassembly that is completely collapsible and nested for transport or storage.

It is a third object of the present invention to provide an assembly which is folded for transport or storage and has a simple and rapid release attachment mechanism.

It is a fourth object of the present invention to provide a robot device assembly for a table tennis sub that uses a scaffold to collect and organize table tennis balls for easy transport or storage.

It is a fifth object of the present invention to provide an assembly having advancing / non-progressing measuring means for measuring a shape and size of a ping pong ball to be used in an assembly to remove a misleading or incorrectly sized ball from the assembly.

A sixth object of the present invention is to provide a robot assembly for a sub which includes a tray installed in the tray for accommodating a plurality of balls to be used by the robot for the sub.

A seventh object of the present invention is to provide a robot assembly for subs provided with the robot installed in the empty tray.

An eighth object of the present invention is to provide a sub-robot assembly in which the sub-robot receives a ball from the front surface.

A ninth object of the present invention is to provide a sub-robot assembly in which the sub-robot receives the ball from the rear side.

According to the present invention, the sub robot assembly of the present invention includes a base container and a robot installed on the rear side so that the lower front part of the robot can receive a table tennis ball in the base container. The assembly is a net structure with an arm pivotally mounted on the back side of the base container, which arms can spread the net between the arms to enclose the robot. The assembly is horizontal from the base container and below the cantilever has a separate ball collector assembly connected to the net, catching the ball caught in the net and feeding it to the sub robot. In addition, the assembly allows the ping pong ball hanging through the forward net suspended in front of the net assembly to pass through the forward net, losing air velocity and dropping it into the ball collector. The assembly also includes a mechanism that can be folded for easy storage and quickly dismantled and attached. In a variant embodiment, the assembly includes a tray for receiving a large amount of balls. The sub-robot is installed on the back of the tray where the sub-robot can catch the ball in the front, or is installed in front of the tray so that the sub-robot can catch the ball from the back. The tray has a quick release installation mechanism by having the assembly installed at the table end. The installation mechanism is hinged to the tray so that the installation mechanism is folded up for transport or storage. The assembly has an optional mechanized panning device mounted on top of the robot to give the lob the ball panning capability. In addition, a fungnet assembly and ball collector device may be added to the assembly, if desired by the user.

Hereinafter, with reference to the accompanying drawings will be described in detail.

Reference numeral 1 designates an embodiment of the robot ball subassembly of the present invention attached to the table tennis table (T).

In general, the assembly 1 comprises a sub-robot 3, a first net assembly 5, a forward net 7, and a remote control 9 connected to the sub-robot 3 by wires 11. ). The remote control 9 is installed on the end of the opposite table T of the assembly 1 for easy access to the player on the opposite table T of the assembly 1. Each component of the assembly 1 is described below.

2 to 7 show the subassembly in detail. The subassembly 1 comprises a robot 3 for a sub which is removably installed in the base container part 13. The function and operation of the sub robot 3 has been described in US Pat. Nos. 4,854,588 and 4,917,380. The robot 3 is removably installed in the container 13 by suitable means such as a nut and bolt assembly, for example wing nut assenbly (not shown).

The base container portion 13 can generally catch a plurality of table tennis balls in a rectangular configuration. The container part 13 has a front vertical panel 15 and a rear vertical panel 17 (FIG. 5). The rear vertical panel 17 installs the robot 3 on the inner surface of the rear vertical panel 17. To support the wing nut assembly (not shown) or other suitable means. The container 13 has two end panels 20, 23 (FIGS. 5 to 7), each of which extends upwards and faces the front to install the ball collector sections 19, 21. It is not higher than the vertical panel 15 and the rear vertical panel 17.

As described in the inventor's patent, the table tennis ball is stored in the container 13 and rolled into the open inlet portion 4 of the robot 3 to engage the internal operating mechanism of the robot 3. From 3). Since the robot 3 is installed on the rear vertical panel 17, the inlet 4 faces the front of the assembly. In use, a pool of ping pong balls is formed in the container 13 to provide continuously to the inlet 4 of the robot 3. The spacers 25 and 25 are slidably installed in the container portion 13 so that when the assembly is folded for transport or storage, the container collects the balls in one place and waits.

As described above, the base container 13 is connected to the ball collectors 19, 21. The ball collectors 19, 21 in the folded position are located on the side walls 20, 23 and are hinged at the hinges 27, 29 via cantilever arms 31, 33, 35, 37, respectively (FIG. 6). To FIG. 9). The cantilever causes the ball collectors 19 and 21 to open the sidewalls 20 and 23 and the sclera 25 when the ball collectors 19 and 21 are folded upward for transport or storage (Figs. 8 to 8). 9 degrees). The bottom edge of the ball collector 19, 20 stops with respect to the top surface of the side walls 20, 23 in order for the ball collector to engage the container 13. The ball collectors 19, 21 are configured to be slightly inclined towards the container 13 so that the balls falling into the ball collectors 19, 21 roll into the pool of balls formed in the container 13. Ping-pong balls fall from the net assembly 5 to the ball collector 19, 21.

The net assembly 5 shown in FIGS. 2 to 5 is a net 41 in which a ping pong ball cannot penetrate / pass. The net 41 is a net in the form of cotton, nylon or other suitable material or thread. The plurality of openings or holes 42 formed in the net 41 are sized so that the ping pong ball hitting the net 41 at any speed cannot escape (FIG. 10). The elasticity of the net 41 allows the ball to pass through the hole 42 through the net 41 while preventing the force of the friendly ball from spreading. There is a solid edge 43 around the net 41 to tie the net in the desired shape (FIG. 2). The solid edge 43 may have a small pocket (not shown) or other means 45, 45a, 45b to engage or receive the arms supporting the net.

The net 41 extends across the plurality of arms. Three arms 47 are provided to support the net 41. Arm 47 is generally a semi-flexible rod of two separable portions 49a and 49b in FIG. 3. The two parts are connected by suitable connecting means 51, which are made of hard rubber pieces or holes, to receive the end arrangement of the parts 49a and 49b. It is also possible to use connecting means such as sleeve assemblies. As shown in FIG. 3, the connecting means 51 comprises a channel, a clip or other means for fastening two separate parts side by side when the arm is disassembled for folding or storing.

Referring to FIG. 5, the arm 47 is pivotally mounted and radiates from the arm fixing means 59 attached to the outer surface of the panel 17. The arm fixing means 59 can move the arm transversely so that the arm 47 can be unfolded for pivoting or use, or folded upward for transport or storage.

The net 41 collects balls 19 and 21 in order to form a wall around the container portion 13 as well as adjacent to the back edges and ends of the ball collectors 19 and 21 and into which the ball cannot penetrate. Attached by appropriate attachment means (not shown) along one side of the top, forming an adjacent nut assembly around the robot 3. Referring to FIG. 5, while the net 41 completely surrounds the robot 3, it is located behind the front edge of the container 13 in order not to hit the raceway.

The second net or forward net 53 (7 in FIG. 1) is hooked in front of the net 41 to enhance the coercive nature of the net assembly 5. As described above, the preceding assembly with a single net assembly is not used to hit the net with enough force for the ping pong ball to strike the canon from the assembly.

The forward net 53 solves these shortcomings. The forward net 53 has a solid edge 53 made of a suitable material or cloth, such as cotton or nylon, to define its shape. A plurality of holes 57 are formed in the net with appropriate sizes or dimensions so that the ping pong ball that hits the net 53 at a predetermined speed passes through the specific hole 57. 9 is for the dimensions of the hole 57 in relation to the table tennis ball. Openings 1 1/2 inches wide by 1 1/2 inches long are the optimal dimensions for the ping pong ball to pass through the holes 57 of the nets 53 and strike the nets 41 at a predetermined speed. 10 degrees).

In FIG. 5 the net 53 is suspended from the net 41 by means of suitable suspension or suspension means 61. The upper part of the net 53 is hooked under the edge 43 of the net 41 to create an opening or gap 63 between the net 41 and the forward net 53.

The arrangement between the rear net 41 and the forward net 53 which works most effectively to catch the ball is shown in FIG. The forward net 53 hangs slightly below the net 41, creating a gap 63 between the top of the net 55 and the top of the net 41. The player catches the ball returned to the net assembly 5 at B1, which falls to the ball collection 19 or 21 by the method described next.

As illustrated by arrow 65, the ball passing through gap 63 and over forward net 53 falls directly into ball collector 21 by hitting net 41. The gap 63 is of such dimensions and positioned relative to the nets 41, 53 such that the ball B passing through the gap 63 hits the net 41 at any angle and falls into the air collection 21. do.

Arrow 67 shows the second possible position of the ball in the net assembly 5. As indicated by arrow 67, the ball B2 at a sufficient speed passes through the opening 57 (FIG. 11) of the net 53, but soon loses its speed, hitting the net 41 and then collecting it. Falls to 21.

The arrow 69 is the position of the ball B3 that has passed through the net 53 at a speed sufficient to bounce the net 41 and then hit the back of the net 53 and fall to the airborne bin 21. As arrow 69 indicates, ball B has lost enough speed or kinetic energy after passing through net 53 and striking net 41 and lacking sufficient speed to penetrate net 53 from the back side. The ball B ₃ bounces off the back of the net 53 and falls into the collecting container 21.

Arrow 71 indicates another position of the ball thrown back in the net assembly 5. The holes 57 (FIG. 11) of the net 53 are of a predetermined size to allow the ball to pass through at a sufficient speed to penetrate the net 53. However, as indicated by arrow 71, if the ball B ₄ is hit at an insufficient speed to penetrate the hole in the net 53, the ball simply collects 21 in front of the net 53. Falls on. A ball struck at an insufficient speed to penetrate the net 53 will lack energy to bounce the net 53 as a foul and fall into the airborne bin 21.

Now looking at the supply side of the ball, when the ball is returned to the net assembly (5) by the player, the net arrangement causes the ball to fall into the collecting bins (19, 21) and rolls towards the pool of balls in the container (13). do. The robot 3 is located at the rear of the container 13 so that the mouse 4 receives the balls from the pool of balls towards the front. Air collection containers 19 and 21 are formed of semi-rigid materials such as moderately lightweight plastics or glass fibers. The depth of the collector is deeper than the robot 3, and the inner bottoms 19a, 21a of the airborne collectors 19, 21 respectively slide down toward the container 13 to serve as ramps for the ball to roll down. As described above, the air collection bins 19 and 21 are in contact with the top surfaces of the face panels 20 and 23, respectively, forming a closed return structure.

The assembly 1 is attached to the table T by suitable mounting means. In the embodiment, the mounting means are supported against the bottom of the table so that the top protruding member 73 has a hard rubbery (not shown) friction member on the bottom left on the top of the table T, and the assembly is placed on the table. And a plate 72 having opposed and outwardly extending projecting bottom members 75 and 76 extending far beyond the length of the top member 73. Attachment assemblies are quick install and quick release assemblies. The assembly is easily attached to the end of the table by sliding the top member 73 and bottom member 75 on the table end. The assembly is quickly and easily removed by lifting the assembly slightly upwards and upwards so that the upper member 73 is moved upward from the upper surface of the table so that the legs 75 and 75 slide under the table. The plate 72 is attached to the outside of the panel 15 by a hinge 77 to pivot the attachment means to deform for prefabricated mobile storage. However, the attachment means can be modified without departing from the scope of the invention.

The assembly of the present invention can be folded as well as folded for storage or transportation. FIG. 1 shows all the components of the game completely assembled for use on a table, FIG. 2 shows the assembly 1 in detail, and FIG. 3 shows the assembly 1 which is primarily folded and folded. do. Blanks 23 and 25 are inserted to gather in the container 13 to store the balls.

3 is for understanding the folded features of the device, which are arm parts 49a and 49b which are disassembled and fixed by the tightening device 51. The rear net 41 and the forward net 53 are folded. The plate 72 is folded along the hinge 77 so that the bottom leg members 75 and 76 hold the robot 3 and are used for storage and transportation.

8-9 are assemblies that are folded to store and transport. Collectors 19 and 21 are in an almost vertical position with nets, arms and robots for subs. The vacancy 25 is in a position to throw the ball into the container 13. Although not shown in the figure, the remote control 9 (FIG. 1) can be stored in the container 13 so that all the components of the assembly are easily packaged. The strap 79 is secured in place by a squeak or a simple latch or other means from the catcher 19 to the catcher 21. 9 is the assembly 1 folded in an optional carrying case 81. The case 81 may be made of any suitable material, for example a mold plastic of two halves 84 and 86 and a hinge 85 (not shown) and a latch 85 to close. This is it. The case 81 also has handle means 83 for transportation.

FIG. 13 shows the sclera 25 in detail. The voids 25 and 25 are made of a suitable material, such as a caterpillar plastic. The diaphragm 23 is slidably installed in a slot formed inside the container 13 as shown in FIG. 6 to generally close the container 13 so as to effectively close the container 13. It is a web structure having. The membranes 25 and 25 function to catch the balls from the outside of the container 13. The sclera 23, 25 is used to hold the balls on the collector face of each sclera and the robot 3 does not engage from the container 13 with the balls, while maintaining the collimator with the net assembly. Referring to FIG. 13, each membrane 23 has a hole 24 formed at one end. The hole 24 is a table tennis ball diameter that is almost completely original. The hole 24 serves to determine the progress / non-progress by measuring the size of the table tennis ball to be used in the assembly. The robot 3 functions most effectively when the size of the ping-pong ball is appropriate and is almost complete. Some of the table tennis balls on the market are of low quality and differ in diameter and shape. In use, the player may pass a ping pong ball through the hole 24. If the ball passes through the hole 24, it is effective in the robot 3 because it means that the ball is appropriate and round. If the ball does not pass through the hole 24, it must be discarded because the ball is too large or uneven in shape to be used effectively in the robot 3. This feature has the advantage of preventing the ball from being caught in the robot 3 and losing time in the game, and preventing damage to the robot 3 by using a ball that does not fit well.

14 and 15 are the panning head assembly of the present invention, which refers to the automatic panning head assembly 91. The panning head 91 comprises plug contacts 93 and 94 and is operated by the player via the rib portion 9 (FIG. 2). Plug contacts 93 and 94 are inserted into the container holes 99 and 101 to make electrical contact with the control box 9. The panning head 91 is controlled by the player to automatically move the levers 83 and 85 to change the side-by-side position of the ball ejector 101 (FIG. 1). 15 is an operating mechanism of the panning head 91. The gear 102 meshes with the levers 83 and 85 while the panning head 91 is rotated to move the co-emitter 10 connected with the lever back and forth when the pan head 91 is connected to the sub robot. The guard 87 extending from the lever base 89 prevents the lever grips 84 and 85 from being entangled in the netting.

16 is another embodiment of the robot tail ping pong net and sub assembly 1 'of the present invention. The assembly 1 'is a pair of ball emitters 10', a first net assembly 5 ', a forward net 7' and a side wing net which prevents the ball from leaking the side edges of the table T.
