Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a ball recovery device for table tennis.

(Prior art and its problems) Conventionally, when collecting table tennis balls scattered on the floor or the ground, the balls were discarded one by one by hand and placed in a basket.

With such a method, the worker is forced to bend his/her back in an unreasonable posture, which causes pain during long hours of work, and the work efficiency is also poor.

Therefore, a method of using a scoop-like tool may be considered, but even such a method only slightly overcomes the disadvantages of the manual method described above.
The ball that was scooped up by the scoop would often fall out before entering the basket, which did not solve the problem.

(Problem to be solved by the invention) The present invention was made in view of the conventional circumstances as described above, and its purpose is to simply apply a slight pressing force from above the ball. To surely and efficiently collect table tennis balls scattered on a floor surface.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the ball collector of the present invention has an elastic material between the edges of each collection port in a collection frame body having collection ports on the bottom and the front surface. A large number of wire rods having a diameter of It is characterized by having a handle for working.

(Function) According to the above configuration, when you hold the work handle and press the bottom recovery port of the recovery frame against the balls on the floor, the balls on the floor are aligned next to each other at the bottom recovery port. It expands the gap between the wire rods and enters the collection frame. After entering, the gap between the wires returns to its original size, preventing the ball from falling off. The collected balls are sequentially moved to a storage body attached above the collection frame, and after the work is completed, they are taken out from the takeout port.

In addition, since the collection port is provided on the front side of the collection frame, balls on the floor near the chamber wall can be easily collected by pressing the front collection port against the chamber wall. It becomes like this.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with

The communication port 7a is an open port at the bottom of the cylindrical storage body 7, and the opening portion is attached to the collection string 2 using an appropriate string material or the like.
It is tied to the upper opening of and connected in communication with the bottom recovery port 1. The communication port 7a is connected to the recovered ball B.
This is the entrance to the storage body 7.

Note that the communication port 7a may be directly connected to the upper opening edge of the collection frame 2, but in this embodiment,
A storage body attachment frame 13 is attached to the recovery frame 2, and the communication port 7a is tied to the attachment frame 13.

The storage body attachment frame 13 has rising frame members 13a and 13a' raised at both ends of the frame member 9a of the collection frame member 2 with a height corresponding to a plurality of balls B.
A horizontal frame member 13b is horizontally suspended between the upper ends of 3a and 13a' to form a front gate-shaped front frame 13c, and from the left and right corners of the front frame 13c, the frame member 9a and the frame member 9a of the recovery frame body 2 are Connecting frame members 13d and 13d' are constructed in an inclined manner toward the opposing corners.

Each frame member 13a, 13 in the front frame 13c
A front collection port 1' is formed in the front portion surrounded by a' and 13b. Further, a collection section 10 is formed in a space surrounded by the storage body attachment frame 13 and the collection frame 2.

The front collection port 1' has the frame material 9a and the front frame 13c.
The above-mentioned wire rod 4 is stretched between the left and right edges of the opening surrounded by , and has the same width as the distance 5 between the upper and lower edges. This creates a gap through which ball B can pass while expanding the gap 5.
They are formed above and below the wire rod 4.

According to the above-mentioned front collection port 1', when the front collection port 1' is pressed against the chamber wall W, the bottom collection port 1
Ball B', which is difficult to collect, that is on the floor F near the chamber wall W, expands the gap (that is, the gap 5) and enters the recovery frame 2. After entering, the gap width returns to its original value, making it impossible for ball B to pass through (drop out).

The recovery unit 10 communicates with the communication port 7a at the top, the bottom recovery port 1 at the bottom, and the front recovery port 1' at the front, and the other surfaces are communication frames 13d, 13d' provided at an angle. This makes it impossible for balls B and B' to pass through, and the bottom collection port 1 and the front collection port 1'
