JP3153301U - Table tennis practice tool - Google Patents

Abstract

An object of the present invention is to provide a table tennis training tool that can be practiced alone in a small place. A cam bar having a table tennis ball fixed on the distal end side and a cam structure on the proximal end side is pivotally supported on a base portion provided on a leg portion and is upright. The base is provided with a brake shoe that allows the cam bar to be hooked in an upright position with respect to the cam structure of the cam bar, and when the cam bar is downward from the horizontal on the side of the base, the cam bar is halfway. A rubber pad that abuts the position is provided. When a ping-pong ball is hit, the cam bar rotates around the base shaft and comes into contact with the rubber pad. The rebound force causes the cam bar to return to the upright position, and stops by friction between the brake shoe and the cam, allowing continuous ball practice. I can do it. [Selection] Figure 1

Description

      The invention relates to a table tennis training tool that is widely used for sports and recreation.

      Table tennis is a sport that is mainly performed indoors, so it is not affected by the weather and can be practiced and competed throughout the year. In recent years, several athletes who have been specially trained since childhood or naturalized athletes are approaching the international level of competition, but both men and women are moving away from the glory of the past years that conquered the world.

JP-A-7-574 JP 7-116292 A Utility Model Registration No. 3113707

    Under these circumstances, a simple and effective table tennis training machine is desired, and various proposals such as Japanese Patent Application Laid-Open No. 7-574, 7-116292, or Utility Model Registration No. 3113707 have been made. There are no useful instruments that can be practiced easily by one person.

      The present inventor has been engaged in the development of basic practice machines for many years of research and examination on tennis, baseball, etc., and it is inexpensive and can be practiced easily alone in a very small space on the floor or table. I came up with a practice tool. That is, a table tennis training tool (hereinafter referred to as this training tool) is provided with a table tennis ball at the tip of a cam bar bent at a substantially right angle and one end connected to a base having a brake shoe and a rubber pad via the cam. . The ping-pong ball at the tip of the cam bar is mounted with a hemispherical rubber or soft plastic having an inner diameter similar to the outer diameter of the table-tennis ball.

      Since the practice tool according to the present invention has a table tennis ball at the tip of a cam bar bent substantially at a right angle, a plurality of continuous and repetitive exercises are possible without requiring a plurality of balls for practice. In repeated practice with this training machine, by hitting a table tennis ball at the tip of the cam bar, after the cam bar is pushed forward, it strikes the base rubber and is immediately pushed back by the rebound, and it is returned to its original position by the brake shoe. Immediately after restoration, the next shot can be repeated. Furthermore, since this training machine is small and light and can be easily carried and installed, it is possible to practice alone or practice the correction of a form in a small place where a table tennis table or the like cannot be installed.

It is a general-view figure of the ping-pong practice equipment of an idea, and has a leg part for practice on the floor. It is an operation | movement figure of the cam stick at the time of hitting of the ping-pong practice tool of an idea. It is a general-view figure of the table tennis training tool which attached the clamp for tabletops of a device.

      The material of the cam bar used in the table tennis training device of the present invention is not particularly limited as long as it does not deform to withstand continuous hitting, but iron and steel bars are usually cheap and useful, and the thickness is about 3 to 6 mm. Is effective. The table tennis ball provided at the tip can be arbitrarily selected by the user for any practice competition. The material and color of the hemispherical rubber or soft plastic to which the ball is mounted are not particularly specified, but the mounting ball is pressed and mounted without using an adhesive or the like, so its inner diameter is almost the same as the outer diameter of the table tennis ball. Since it is desirable to approximate and have flexibility, it is desirable that the hardness is about 40 to 60 JISA hardness. The abutting rubber stretched on the base that is repelled by the impact of the cam rod needs to be strong enough not to be cut by repeated repulsion, and can be selected from natural rubber, nitrile rubber, and ethylene / propylene rubber. Further, it is also effective that the base of the training machine is provided with a table clamp for practicing on a leg or table whose height is adjustable for practicing on the floor.

Example 1
As shown in Figure 1, a table tennis ball for practice was set on the tip of a cam bar with a thickness of 4 mm, a horizontal part of 100 mm, and a vertical part of 200 mm via an ethylene-propylene rubber hemisphere with a JISA hardness of 50, an aluminum cam, and It was connected to a base with an aluminum rubber pad and high-density polyethylene brake shoes. A natural rubber pad rubber of width 12mm, thickness 2mm, and JISA hardness 45 was set on the pad rubber base, and a table tennis training tool with a height adjustable leg of 25mm was created.

(Example 2)
A steel clamp was attached to the base of the product having the same specifications as in Example 1 instead of the legs, to create a table tennis training machine for table mounting.

      The designed table tennis training machine is a small, lightweight and portable table tennis training device that can be practiced by one person on a small floor or table, and can be used widely from infants to old age.
