Description

[Detailed description of the invention] (Subject of the invention) The present invention is a table tennis table that can be used as an assembly type table tennis table, especially as a general ping pong table, but especially for practicing shots, smashes, or stop balls even in a small room. Regarding the table tennis table that can be used.

(Background) Table tennis is a widely popular indoor ball game, and it is suitable for the petite Japanese people's physique, and it is not expensive or space-consuming like tennis, so it is popular among enthusiasts, including players. The number is extremely large. However, in order to play or practice real ball games in earnest, a certain amount of space is still required.
However, on average, Japanese homes are so small that they are criticized by Westerners as rabbit hutches, and it is almost impossible to hold a table tennis match or even practice in a normal home, especially in a condominium or apartment. .

(Purpose) The present invention is an assembly type table tennis table, which allows basic practice such as shots, smashes, and stop balls, especially in a small room such as a condominium or apartment, and is easy to assemble. To provide a table tennis table that does not take up much space for storage and can also be used for games if necessary.

(Structure) In order to achieve the above object, the present invention provides a table tennis table with a pair of beams that can be folded or divided, a pair of joists that can be folded or divided, and between the beams and between the joists. A set of a plurality of girders that maintain the beams at a constant interval in the horizontal plane, an upper frame-like frame made up of each beam material and girder material, and a lower frame-like frame made up of each joist material and girder materials. It consists of a plurality of pairs of pillars that hold the frame at a constant vertical distance, and each girder and each pillar are fitted into brackets attached to the connecting beams and joists, respectively. In addition, a top plate is placed on one half of the upper frame, and a ball catching net is attached to the remaining half. That is, the table tennis table according to the present invention is specifically constructed by combining the following members and parts.

A pair of beams that can be folded or split; A pair of joists that cannot be folded or split; A plurality of girder members that maintain a constant distance between the beams and joists; Each beam formed by each beam and joist A plurality of pairs of columns that hold a set of frames at a constant vertical spacing Brackets for inserting girders and columns installed at corresponding positions on each beam and joist One half of the upper frame A top plate for forming a coat surface that is placed on the upper frame; A removable frame for laying a net that is placed on the remaining half of the upper frame; As explained in the examples below, each of the above The member is constructed by connecting the upper frame and lower frame, which are obtained by connecting beams and joists with girder materials, respectively, using pillar materials, but as a practical matter, it is necessary to insert girder materials and pillar materials into the brackets. Since it is difficult to obtain a tight connection by simply using the above methods, it is desirable to use known tightening means in combination to secure the connection between each member.
As a means for this, it is certain that each member is connected through a tightening means such as a bracing wire and a turnbuckle. The dimensions of each member in this invention are:
The size of a regular ping pong table is determined as standard as shown below.

Total length of beam material: 274cm Total length of joist material: Approximately 200cm Total length of upper girder material: 152.5cm - (width of beam material x 2) cm ~
70cm Total length of lower girder material: 152.5cm - (Width of joist material x 2) cm
~70cm Total length of pillar material: 76cm - (thickness of top plate + thickness of upper spar material + thickness of lower spar material) cm This stand is preferable for personal practice.

(Function) Since the assembly type table tennis table according to the present invention has the above configuration, it can be easily disassembled or assembled. In particular, the length of the beam material is shortened to about 1/2 of the regular length, which is not only suitable for practicing returning balls in a small room, but also faster than the regular one because the area of the opponent's court is smaller. You can learn accurate typing techniques. By configuring the opponent's court surface with a net stretched over a frame, it is possible to judge the quality of serves and hits, and to collect served and hit balls in one place. By configuring the opponent's court surface with a net stretched over a frame, it is possible to judge the quality of serves and hits, and to collect served and hit balls in one place. In addition, when using the main table for personal practice, it is preferable to automatically throw the ball using a simple ball throwing device.

(Example) Hereinafter, an example will be given to illustrate the mode of implementing the invention, but of course, this is merely an illustration and is not intended to limit the spirit of the invention.

Figure 1 is an overhead perspective view showing the main parts of the proposed device assembled in use, Figure 2 is its right side view, and Figure 3 is
The figure is a partially enlarged perspective view showing the relationship between the net mounting bracket and the proposed table tennis table.

The whole consists of a pair of beams 3, 3 that can be folded into two by hinges 4, 4 in the center, and four girder members that connect the beams at both ends and in the center (however, in Fig. , the girder material on the back side is not shown) 5,
5,... an upper frame 1 consisting of a pair of non-foldable joists 6, 6, and four girder members 7 that connect both joists at both ends and intermediate portions;
A lower frame 2 consisting of 7,... and four pairs of pillar members (8, 8; 8, 8...,
However, in Fig. 1, the pair on the back side is not shown), and each beam member 3 and 6, each girder member, and each column member are connected to brackets 9, 9 attached to the front two...
This is done by fitting both ends of each beam member and each column member into each other. The frames and the joists are further diagonally diagonally fixed by retaining wires 11, 11, . . . with turnbuckles 10.

When the proposed table tennis table is used for personal practice, a ball catching net with an asymmetric trapezoidal cross section is attached in place of the front top plate. This net 12 has a frame material 13 with four pins 14 attached to each peripheral edge thereof = 13a, 13b, 13c
and 13d and mounted on the front part of the stand (the pin 14 fits into the pin hole 15 on the corresponding beam member 3). The net 16 is fixed by a pair of net fittings 17, which sandwich both ends of the central frame member 13a and the beam member 1 below.

Incidentally, an opening 18 is bored in the bottom of the upper net 12, and a ball catching basket 19 is placed directly under this opening to catch the ball B that has fallen into the main net (second (see also figure). In addition, when adopting this practice method, the top plate 2 placed on the platform on the practitioner's side
It is preferable to provide an automatic ball throwing device 21 that automatically throws the ball toward zero.

(Effects) Since the present invention has the above configuration, it is possible to provide a table tennis table that allows effective table tennis practice even in a small room, does not take up space for storage, and is easy to assemble and disassemble. Through this, they have made a great contribution to the lives of people not only by improving their skills but also by improving their physical education.
