Description

Squash ball automatic launcher {Squash ball machine}

The present invention relates to a squash ball automatic launcher for automatically launching a squash ball, and in particular, by continuously and automatically firing in various directions and speeds, it does not require a practice partner, and even beginners who are not familiar with squash This will allow you to practice or exercise efficiently.

Squash is a sport in which you play a ball with your opponent on a squash court indoors with a relatively small and light rubber ball. It is a sport that can be lightened in a relatively small indoor space because it uses walls, and is suitable for modern people who have a lot of time and space restrictions.

However, it is necessary to send the ball to the opponent by using a light and elastic rubber ball and match the ball to the wall. Therefore, if you do squash games or hitting each other between beginners, you will not be able to send the ball to the opponent correctly. There are disadvantages.

Therefore, in the conventional squash practice method, a squash expert bounces the ball into the wall one by one with a racket and drops it to the exerciser, and the practice is performed by the player hitting the ball again. In other words, squash beginners can practice only if they are skilled squashers, but despite the fact that squash is a good fit for modern people, it is difficult for individuals or beginners to exercise efficiently and continuously.

In addition, the squash is a small indoor space, so the size of the launcher is small so that it does not interfere with the movement. As a result, the structure of the existing baseball batting simulator or tennis ball launching device is not suitable for the squash ball launching device, but the squash reflects the characteristics of the squash. There is virtually no ball launcher.

The present invention was devised to eliminate the above problems, and it is possible to efficiently practice even individual or beginners, so that the efficiency of exercise and continuity of exercise can be maintained, and the space constraint is large and it is different from other ball games. Another object of the present invention is to provide a squash automatic launch device having a structure that reflects only the characteristics of the squash using the wall. When explaining the technical problem that the present invention intends to achieve as an automatic ball-operating device for squash, first, the motor is only at the moment of launching the ball to compensate for the battery and motor stability, which is a disadvantage of using a small motor due to space limitation. It is designed to rotate at speed to extend the life of battery and to prevent overheating of small motor. Secondly, squash is characterized by hitting the ball against the wall. Therefore, the ball's spin direction when the ball hits the wall is affected by the direction of motion of the ball after the impact. Referring to Figure 4, when using the spin control device provided in the present invention, the ball rotates counterclockwise, so when it bounces against the wall, it bounces up with a convex parabolic orbit, which is a beginner because the ball has a long flight time. It is suitable for practicing or exercising. Figure 5 is a case of firing the ball without the spin control device in this case, the speed of the ball is a little faster and bounces back because it is similar to the actual game is suitable for the skilled person. It is another object of the present invention to provide a squash-only ball launching device by applying a spin control device in accordance with the characteristics of the squash. In summary, the present invention aims to provide a squash-only ball launcher that can be used conveniently for beginners and experienced practitioners and exercisers utilizing the features of squash only.

Example Configuration

This will be described with reference to Figs.

The present invention is largely composed of the storage device of the ball, the input device for passing the ball into the interior, the transfer device for moving the ball to the launch unit, the launch device for firing the ball.

In the future, each component will be described in more detail in the following order: storage, input, transport, and launch.

The storage device consists of a fence (11) equipped with a hinge (13) which can be folded to hold several balls, and a cloth (12) that is opened and folded by both fences. It is possible and when used, the fence is spread out to hold the ball. In addition, the bottom is slightly inclined so that the ball is collected into the input unit 22 of the input device.

The input device is composed of an input part 22, a vertical input pipe 23, and a horizontal input pipe 24. The input unit 22 is a portion connected to the storage device, and the vertical input tube 23 has a structure connected to the horizontal input tube 24. It is a structure to prepare for safety accidents such as a human hand entering the transfer device, and may be replaced with a single pipe at the discretion of the operator.

The conveying apparatus 3 is composed of rods 33 constituting the crank, a motor 34 in charge of the conveying, and a partition 35 for guiding the crank and the ball to be conveyed in a straight line. It serves to send. The process of converting the rotational motion of the motor 34 into the reciprocal linear motion by the crank is a technique known to those skilled in the art. The transport rod 36, which is the outermost rod of the crank rod that is responsible for the actual ball transfer, has a long rectangular parallelepiped shape and has a structure such that only one ball is transferred from the feeding device. The feeder feeds the ball until the ball is introduced into a pair of rollers 41 rotating at high speed in opposite directions, and is returned by the crank after the ball is fired. It is possible to feed one ball into the hinge 39 to fix the ball when the ball is fed from the input device to the transfer device so that only one ball is introduced in the transfer device. 6, this hinge 39 is flipped when the crank bar 36 pushes the ball.

The crank bar of the transfer device has a switch 38 through which the entire current of the present invention passes. This part has a structure in which the current of the entire circuit flows only when it is in contact with another switch 37 fixed above the crank. That is, the crank acts as a switch so that the firing motor 42 operates only when the switches 37 and 38 are in contact with each other. This part causes the firing motor 42 to rotate at full speed only at the moment of firing the ball.

The launch device is composed of a pair of rollers 41 and a pair of motors 42 for rotating the rollers, a pedestal 45 for supporting the motors, and a foldable spin control rod 43. The ball conveyed from the conveying apparatus is fired by a pair of rotary rollers 41 which rotate at high speed in opposite directions by a pair of motors 42 and spin is generated by the spin control rod 43, or spin control is performed. When the rod 44 is folded, it has a structure that is fired without a spin. In consideration of the fact that the motor 42 is used for squash balls and has a large space constraint, it is preferable to use a small DC motor when carrying out the present invention. The rotating roller 41 may change the material at the discretion of the practitioner, but it may be preferable to use a rubber material similar to that of the squash ball as the outer surface contacting the ball. The spin control device 43 may also be embodied in a plate or other material with wheels that can be rotated at the discretion of one of ordinary skill in the art. The roller gap adjusting device 44 for adjusting the gap between the firing motors 42 is composed of a bolt and a nut, and is attached to the support 45 of one motor of the pair of motors. Referring to Fig. 7, the tightening of the bolts increases the spacing between the motors and the loosening of the bolts reduces the spacing between the motors. This allows you to maintain the proper firing interval depending on the type of squash ball.

The storage device, the input device, the transport device, the launch device is fixed by a box 71 of a rectangular parallelepiped and a support 72 inside the box.

Action of Example

First, the ball stored in the storage device enters the input unit 22 of the input device. The ball is conveyed to the conveying apparatus by the vertical inlet tube 23 and the horizontal inlet tube 24 connected to the inlet unit 22. When one ball is being transferred, the end of the horizontal feed tube 24 is blocked by the transfer rod 36, and a hinge 39 is provided at the place where the inlet of the feed device and the feed device is connected so that one or more balls are fed into the feed device. If the feeder feeds the ball and returns, it will be put back into the feeder again. Due to this principle, when several balls are stored in the storage device, the balls wait to be introduced into the transfer device from the storage device, the vertical injection pipe 23 and the horizontal injection pipe 24. This process is illustrated in figure 6.

One ball introduced into the conveying device is moved toward the firing portion by the crank operated by the motor 34. As the motor 34 for operating the crank, it is preferable to use a geared motor having an RPM of 5 to 10 equipped with a reduction gear.

The conveyed ball is to be launched by the rotary roller 41 of the launching device is to perform a different movement depending on whether the spin control device 43 is operated. The spin control device 43 causes the ball fired by the roller 41 to bounce the spin control device 43 and then fire so that the spin of the ball is counterclockwise as shown in FIG. 1 so that the ball bounces back against the wall. It is designed for the purpose of adjusting the orbit to be a convex parabolic shape. This track is suitable for squash beginners. If you do not use the spin adjuster 43, the ball will be fried to the wall after the ball comes back to the height of the exerciser's knee will be a suitable practice for the skilled person.

The firing motor 42 operates only while the switches 37 and 38 connected to the feeder are in contact. Even with a long operation, the motor can turn the motor only at the moment of firing the ball. do. This ensures the stability of small motors and the efficient use of batteries. Therefore, it is preferable that the firing motor 42 uses a small high speed DC motor having a shortest maximum speed arrival time.

As described above, the squash automatic ball firing device according to the present invention is to enable continuous and efficient squash practice, exercise, and enjoy individual and beginners efficiently by firing the ball uniformly without disturbing the movement. To provide an environment.
