Description

[Detailed explanation of the invention] This invention relates to a batting practice machine that lightly throws the ball just in front of the batter in order to practice like throwing up a ball and hitting it yourself.

Conventional batting practice machines that shoot the ball at a considerable speed from a distance and hit it at the batter have been known in many different formats, but the main idea is to throw the ball up yourself. The purpose is to provide a ball throwing machine for practicing things like hitting.

The present invention will be explained with reference to the embodiment shown in the drawings.
Reference numeral 1 is an underframe, and a bearing frame 2 is erected at a predetermined location, a predetermined portion of an operating rod 3 is pivotally supported on this bearing frame, and a lever 4 of the operating rod provided below the pivot support is attached to the lower end of the lever 4. The rear end of a tension spring 6, which is adjustable in tension and relaxation, is hooked to a latch 5 whose front end is provided at the front of the underframe.
The operating lever 3, which is raised by the tension spring, is restrained from rising to a fixed position by a stopper 7 whose lower end is attached to the underframe 1, and on the front side of the lever 4,
An engagement pin 10 fixedly planted on the upper end side surface of the T-shaped lever 9 whose lower end is pivotally supported 8 on the bearing frame 2 is brought into contact with the engagement pin 10, and a return plate whose front end is hooked to the stopper 7 is attached to the upper end of the lever. The rear ends of the springs 11 are connected, a pusher ring 12 is provided at the rear end of the lever 9, and an engagement claw 13 is formed at the rear end of the operating rod 3, and the underframe is placed on the path through which this goes up and down. A movable latch 16 is installed on the side surface of the support frame 14, which is erected with the lower end attached to the support frame 14, and is pivoted at a suitable intermediate position 15, and a claw 17 with which the engaging claw 13 engages and disengages is formed on the front side of the movable latch. A recess 18 is provided, the front end of a wire 19 is connected to the upper end of the movable latch, an expansion spring 21 is arranged on the wire between the movable latch 16 and the wire support 20, and the rear end of the wire is connected to the front end of the wire 19. is connected to a support 24 of a petal 23 of the foot operation device 22, and when the pedal 23 is stepped on, the support slides a little backward on the seat plate 25 of the foot operation device and locks the movable latch 16. When the engaging pawl 13 provided at the rear end of the operating rod 3 is deeply engaged and the foot is removed from the pressed petal, the wire 19 returns to the front, that is, the old position, by the expansion spring 21, and at the same time the movable latch 3 16 stands up, and the rear end of the actuating rod 3 that is locked to the edge of the notch 18 is released from the instantaneous engagement part, and the actuating rod 3 is moved by the tension spring 6.
The spring lever 26, which is connected to the front end of the spring lever 26, strongly returns to its old position at the stopper 7 and is stopped at the stopper 7.
Ball 28 on ball support ring 27 provided at the tip of
It is designed so that it curves upward and bounces away.

Next, to explain the operation of the present invention configured as described above, the batter stands with the putt near the foot control device 22 located at the rear of the underframe 1, and when making a batting action, Push down the lever ring 12 from above with the tip of the foot or butt to push down the lever 9, and at the same time step on the pedal 23 with your foot to move the movable latch 16 connected to the front end via the wire 19 to the position shown by the solid line in Figure 1. On the other hand, when the lever rod is pushed down and the front end rotates about the shaft support 8, the engagement pin 10 fixed on the front end is rotated by the lever 4 of the operating rod 3.
, the engagement pin 10 pushes the lever 4 and moves the operating rod 3 from the position shown by the solid line in FIG. When it is pushed down, the tension spring 6 is extended, and the movable latch 16 has previously been moved to the position shown by the solid line in FIG. The operating rod 3 is latched to the claw 17, and regardless of the action of the tension spring 6, the operating rod 3 is latched to the movable latch 16 and cannot return to its normal state, and stops at the position shown by the chain line.Thus, when the preparation is completed, Place the ball on the support ring 27, hold the butt and prepare to hit the ball, and at the same time take your foot off the petal 23, and the support ring 2
4 slides on the seat plate 25 by the release action of the stretched expansion spring 21, the petal returns to its normal state, and the movable latch 16 also rotates from the position shown by the solid line in FIG. 1 to the position shown by the chain line. Because it moves, the momentary actuation rod 3 of this rotation
The engaging pawl 13 disengages from the recess 18 of the movable latch, and the operating rod 3 momentarily rises due to the elasticity of the extended tension spring 6.
The ball is stopped by the stopper 7, and the ball flies toward the batter due to the action of the spring lever 26, which acts simultaneously with the sudden stop of the operating lever, so the batter hits the ball without missing a beat.

If you want to continue batting practice, you can repeat the above operations.

Since the present invention has the above-mentioned effects, the batter can practice hitting the ball freely at any time, and if the net is placed in front of the ball, it does not require a large space.
It is possible to practice freely even in a small space, and since the pitching device has an extremely simple structure as described above, breakdowns are rare, making this invention an extremely effective tool for physical education. It is something.
