Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ball collector for collecting table tennis balls scattered on the floor of a table tennis hall or the like.

(Prior technology) Conventionally, this type of ball recovery device was developed using the Utility Model 63-43565.
There is one disclosed in the publication No.

This ball collector is a cylindrical storage body with a take-out port on the top surface and a collection port on the bottom surface, and a large number of elastic wire rods are stretched in parallel to the collection port. Then, when the storage body is lifted and the collection port is positioned directly above the balls, and the storage body is pressed against the floor surface, the balls are pushed apart between the wire rods by the pressing force and enter the storage body.

(Problems to be Solved by the Invention) According to the conventional ball recovery device, as described above, it is necessary to move the storage body up and down every time a ball is to be recovered. Furthermore, when taking out the ball, the storage body is placed upside down directly above the collection basket and the ball is dropped into the collection basket.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to make it possible to collect balls with a simpler operation without having to move the collecting device up and down one by one, and to also make it possible to retrieve the balls. Another object of the present invention is to provide a ball retrieval device that is easy to use.

(Means for Solving the Problems) In order to achieve the above object, the ball collector of the present invention includes a collection tube portion having a collection space inside, a support member rotatably supporting the collection tube portion, and a support member rotatably supporting the collection tube portion. The collection cylinder part consists of a working handle fixed to a supporting member, and the collecting cylinder part has side plates fixed to both ends of the connecting rod, and elastic wire rods are arranged along the entire outer periphery of both plates at intervals slightly smaller than the ball diameter. It is characterized in that a large number of wire rods are stretched, and at least one of the wire rods is connected to a desired tightening means so that the wire rods can be relaxed.

(Function) According to the above means, when the collecting cylinder placed on the floor is pushed in the direction of the ball to be collected by holding the working handle, the collecting cylinder is pushed by its own weight to the lower end of the circumferential surface. It rolls on the floor while sequentially pressing the wire rods on the floor. The pressing force causes the balls on the floor to spread out between the wire rods and enter the collection space.

Furthermore, when the latching means is operated to loosen the tension of any wire, the distance between this wire and an adjacent wire increases, making it possible to take out the ball in the collection space.

(Example) One embodiment of the present invention will now be described with reference to the drawings. In Figures 1 and 2, reference numeral 1 denotes a recovery tube portion having a recovery space 1a therein, which is rotatably supported by a support member 2, and a working handle 3 is fixed to the support member 2.

The collection cylinder 1 has disk-shaped side plates 12, 12' fixed to both ends of a cylindrical connecting rod 11 having a desired length, and holes 13 facing each other in the outer edge portions of the respective side plates 12, 12'. , 13' are drilled in large numbers around the entire circumference at intervals slightly smaller than the ball diameter,
A wire rod 14 is stretched between the holes 13 and 13'.
A recovery space 1a is formed in a portion surrounded by the side plates 12, 12' and the wire rod 14.

In addition, the recovery cylinder part 1 has a through hole 15 in the center of the side plates 12, 12' that communicates with the hollow interior of the connecting rod 11, and a support shaft 16 is formed in the through hole 15 and inside the connecting rod 11.
, and both ends of the shaft 16 are inserted into the respective side plates 12,
12' is projected outwardly. Male screws 16a are cut into both ends of the support shaft 16.

The wire rod 14 is a string body made of synthetic resin, wire, etc. and has a desired elasticity, and forms an interval between adjacent wire rods 14 for collecting balls.

Further, one end of an arbitrary wire 14' in the collecting cylinder 1 is connected to the fastener 4 and is stretched so as to be relaxed.

The fastener 4 is attached to one side plate 1 as shown in FIG.
2' is provided with a claw metal fitting 41 attached to the outer surface so as to be freely raised and lowered, and a ring 43 that engages with the hook 42 when the claw metal fitting 41 is raised to prevent the claw metal fitting 41 from falling down. Then, one end of the wire 14' is connected to the claw metal fitting 41, the wire rod 14' is stretched with the claw metal fitting 41 folded down, and the tension of the wire rod 14' is loosened with the claw metal fitting 41 raised. It's getting old.

The support member 2 is attached to both side plates 12 and 12' of the collection cylinder section 1.
The side ends of the upper side part 21 parallel to the wire rod 14 are bent to the center of the side plates 12, 12' to form side parts 22, 22. At the tip of 22, there is an opening 23 that loosely fits into the support shaft 16.
is provided. And the male screw 16 of the support shaft 16
side part 22 by nuts 5, 5' screwed into a.
The recovery cylinder part 1 is rotatably supported with the two sides in between.

Further, the support member 2 is provided with a protruding rod 24 on the upper side 21 that protrudes in a direction facing the side portion 22, and the tip of the handle 3 is connected to this protruding rod 24. The handle 3 has a desired length and has a grip portion 31 formed at its base end.

Further, a guide member 6 is attached to the outside of one side portion 22 of the support member 2.

The guide member 6 extends from the end of the support shaft 16 to the side plate 1.
It consists of a support rod 61 extending to the outside of the outer edge of the cylinder 2, and a guide roller 62 attached to the tip of the support rod 61 parallel to the support shaft 16. The circumferential surface is formed into a tapered shape.

In addition, 7 in the figure is a resin cover attached to the outer edge of the side plates 12, 12', which covers the holes 13, 13' and protects the ends of the wire rod 14.
It covers the circumferential surface of 2' and acts as a cushion between it and the floor.

According to the above configuration, when the collecting cylinder part 1 placed on the floor surface F is pushed in the direction of the ball B to be collected by holding the handle 3, the collecting cylinder part 1 is moved by its own weight to the wire rod at the lower end of the circumferential surface. Roll on the floor F while sequentially pressing 14 onto the floor F. Then, due to the pressing force, the ball B on the floor F expands the gap between the wire rods 14 and enters the collection space 1a, and then the wire rods 1
Due to the restoring force of 4, the interval returns to its original width and prevents the recovered ball B from falling. At the same time, the guide roller 62 rolls on the floor surface F, and due to its peripheral surface,
The ball B located at the edge of the floor F is moved toward the center of the floor F (FIGS. 3 to 5).

After collecting the ball B, the claw metal fitting 41 is raised to loosen the tension on the wire rod 14', and the distance between the wire rod 14' and the adjacent wire rod 14 is widened, and the ball B in the collection space 1a is taken out. At that time, hook the ring 43 on the hook 42 to prevent the claw metal fitting 41 from falling down,
By keeping the wire rod 14' in a loosened state, there is no possibility that the taking out of the ball B will be interrupted due to the claw metal fitting 41 being accidentally knocked down during the work of taking out the ball B (FIG. 6).

In this embodiment, by providing the guide roller 62, it became possible to easily collect the ball B located at the edge of the floor surface F.

(Effects of the Invention) The present invention has the following effects due to the above-mentioned configuration.

A large number of balls can be successively collected by a simple operation of rolling a collecting tube part on the floor without lifting the collecting device one by one or pressing it against the floor. Furthermore, the collected balls can be taken out simply by loosening the tension on the wire without turning the collecting device upside down.

Therefore, it is possible to provide a ball recovery device that can perform ball recovery work more efficiently.
