Description

  The present invention relates to an improvement in a method for discharging a collected ball of a ball collecting tool for table tennis practice using a large number of balls, in particular, a ball collecting tool formed by stretching a linear object on the collected spherical surface.

As a method for collecting a large number of balls scattered on the floor during table tennis practice, a scooping method using a net for catching insects as shown in FIG. 7 is often used at present. Furthermore, methods such as Patent Documents 1 to 4 have been proposed. These are not skimmed, but the linear object 7 is stretched in an opening surrounded by the frame 2 of the skimming-type ball collecting tool of FIG. 7 at intervals smaller than the diameter of the ball, and the linear object 7 is stretched. This is a method of collecting the balls passing between the linear objects 7 by covering and holding the exposed surface from above the balls.

In the case of this method, when the collected balls are used or transferred to another container, it is necessary to take them out from the holding unit that collects and holds the balls. In Patent Documents 1 to 4, each device is devised. The present invention takes out the method of the ball, i.e., opening and closing process of the ball release portion during Haikyu, Atsumaridama portion and Haikyu part on the particular patent document 4 shown enclosed by it are frame 2 opening amount of the flush It is related with the improvement of the opening and closing method of what provided.

Collecting balls instrument present invention is an improvement subject on surrounded by the opening amount of the flush in the frame is provided with a a Atsumaridama portion and Haikyu section are those easy to use if well. However, this is because the Atsumaridama portion and Haikyu portion on the opening portion of the same plane in the same frame is provided, resulting in spilled moved towards Haikyu portion the ball Atsumaridama secondary in Atsumaridama portion There is a thing. Therefore, as a method for preventing this, Patent Document 4 has devised measures such as setting the size (width) of the ball throwing portion to be 1.5 times or more of the great circle of the ball or using a fall prevention tool.

  However, further improvement is considered necessary in order to reliably collect and discharge balls with practical smoothness. For example, in order to smoothly and quickly discharge the collected balls, it is desirable to ensure the size (width) of the ball discharge portion as it is. However, simply increasing the size of the ball will cause the collected ball to move toward the ball exit and fall. Therefore, means for preventing the fall such as a fall prevention tool is required.

  Patent Document 4 proposes a cylindrical object, a sheet-like object, a plate-like object, a massive object, or the like as a fall prevention tool. If these methods are used, it is surely effective in preventing unexpected spillage from the ball discharge part. However, there are times when it is difficult to open and close cylinders and sheets, and for plates, etc., balls may spill out during collection or carrying, and improvements are desired. ing. Therefore, the present invention aims to solve this problem during ball discharge.

The present invention has solved the above problem by the following method. That is, the ball collecting portion 5 and the ball discharging portion 6 are arranged on the same plane of the opening portion surrounded by the frame 2, the boundary portion 4 is provided between the ball collecting portion 5 and the ball discharging portion 6, and the holding portion is further provided on the upper surface portion thereof. In the table tennis ball collecting tool provided with 3, in order to control the movement of the ball 12 collected in the ball collecting unit 5 to the ball discharging unit 6, the elastic holding member 9 is held on the upper surface portion of the boundary 4. The problem was solved by a method of controlling the distance ( space for moving the ball 12 ) between the holding part 3 and the boundary part 4 by mounting the part 3 and expanding and contracting the presser 9 .

  The collected ball is temporarily held between the ball collecting portion and the holding portion, and then moved and discharged over the boundary between the ball collecting portion and the ball discharging portion. The above-mentioned problems were solved by the method of freely controlling the opening and closing of the space by expanding or narrowing, and the following effects were obtained.

(B) Conventionally, it was necessary to reduce the width of the discharge part or use a fall prevention tool, etc., but the ball movement from the ball collecting part to the ball discharging part can be controlled at the boundary part. As a result, there was no unexpected spilling of the ball, and the size of the ball-departing part could be set large enough, and the ball could be discharged very smoothly and quickly. The fall prevention tool used in Patent Document 4 is no longer necessary.
(B) Since the elasticity of the rubber-like material is used, the opening and closing of the space on the boundary for ball throwing can be done by pulling the holding part etc. upward or by hand in the same posture as when collecting balls. It can be done with one-touch operation and is easy to use and easy to use.
(C) Since the opening and closing of the space on the boundary can be controlled, the ball cannot move freely from the collecting part to the discharging part, and the ball rolls down during collecting, carrying or storing. There is no worry and it can be used with confidence.
(2) When you want to move the collected ball from the collecting tool to a container, etc., bring the draining part over the opening part of the container and pull the holding part above the boundary part upward by hand. The ball moves from the ball collecting unit to the ball discharging unit, is discharged, and is dropped and accommodated in a container or the like. If you release your hand, the space on the border will close and you can collect and carry again. Even when the hand is released in the middle of discharging and the ball remains in the holding portion, there is no hindrance to collecting and carrying the ball and it is very easy to use.

An original ball-collecting tool that divides the opening in the frame into a ball-collecting part and a ball-collecting part. The front view of a ball-collecting tool equipped with the presser having elasticity according to the present invention. The top view of a ball collecting tool same as the above. X-X 'visual field sectional drawing of a ball collecting tool same as the above. A figure (front view) of collecting balls with the same ball collecting tool. The figure (front view) which is discharging the balls collected by the same ball collecting tool. A commercially available scooping-type ball collecting tool.

In this type of the ball collecting tool 1, that is, the ball collecting tool 1 in which the ball collecting portion 5 and the ball discharging portion 6 are provided on the same plane of the opening portion surrounded by the frame 2, and the holding portion 3 is provided on the upper surface portion thereof. The ball 12 collected by the ball collecting unit 5 is once held between the ball collecting unit 5 and the holding unit 3, and always passes through the upper part of the boundary 4 between the ball collecting unit 5 and the ball discharging unit 6 at the time of ball discharging. It moves and is discharged from the ball discharging unit 6. Therefore, if the space for movement, that is, the distance between the holding portion 3 and the boundary portion 4 (opening portion for moving the ball 12) is opened or closed, the ball discharge can be controlled.

  Therefore, as a result of various investigations on the control method, a flexible net-like material or cloth-like material is used as the holding portion 3, and the flexibility is utilized by using a material having elastic properties of rubber-like material. It has been solved by widening or narrowing the characteristic holding part 3.

As the rubber-like material, a presser 9 having elasticity such as a string-like, belt-like, rod-like, cloth-like, net-like or a combination of those having rubber-like elasticity or a composite material thereof is used. Then, it is attached to the holding portion 3 on the upper surface portion of the boundary portion 4 . At that time, the distance ( space ) between the holding part 3 and the boundary part 4 is made smaller (narrower) than the diameter of the ball 12. Further, examples of the presser 9, the distance between the holding portion 3 and the boundary portion 4 (space) to use those having stretchability that a rather larger than the diameter of the ball 12 (broad rather) by pulling it .

If attached in this manner, the collected balls will not spill out toward the ball-departing part even when the ball is being collected or carried as long as the hand is released from the presser 9. Further, when it is desired to drain the ball, if the presser 9 is pulled away from the boundary portion 4, a space is formed between the holding portion 3 and the boundary portion 4 so that the ball 12 can pass therethrough. It moves toward 6 and is discharged.
The present invention will be further described below with reference to examples.

  The present embodiment is an embodiment using a presser 9 having elasticity. FIG. 2 to FIG. 6 show examples of the embodiment. 2 is a front view of the ball collecting tool, FIG. 3 is a plan view, FIG. 4 is a cross-sectional view taken along the line XX ′ shown in FIG. 3, and FIGS. Figure).

  As the ball collecting tool before mounting the presser 9, the ball collecting tool shown in FIG. 1, that is, the opening part surrounded by the frame 2 is divided into the ball collecting part 5 and the ball discharging part 6 at the boundary part 4, In addition, a ball collecting tool (hereinafter referred to as “original ball collecting tool”) in which the ball 12 can smoothly pass through the size (width) of the opening of the ball discharging unit 6 was used. FIG. 1 shows a perspective view (A), a front view (B), a plan view (C), and a bottom view (D) of the prototype ball collecting tool 11. Note that the prototype ball collecting tool 11 is not limited to FIG. 1 but is shown as one of the embodiments.

  This prototype ball collecting tool 11 has a rigid frame 2 and a holding part 3 for holding the collected ball (using a flexible net that can follow the expansion and contraction of the presser 9) and handling operation. It is configured with a handle 8 for use. The opening surrounded by the frame 2 is composed of a ball collecting portion 5 for collecting the balls and a ball discharging portion 6 for discharging the collected balls (both formed so that the balls 12 can pass smoothly). In the opening, the linear object 7 is stretched at a distance narrower than the diameter of the ball 12 to form the ball collecting portion 5, and the ball discharging portion 6 is left in an open state. This is an example in which a partition plate is provided to form the boundary portion 4.

  As shown in FIGS. 2 to 4, the first embodiment of the ball collecting tool 11 is provided with a holding tool 9 to form the ball collecting tool 1 according to the first embodiment. As the presser 9, a presser 9 having various shapes can be used. In this embodiment, a flat strip having elastic rubber elasticity is used, and this is used as a holding portion 3 on the upper surface portion of the boundary portion 4. Attach outside (upper side in the figure).

Since when wearing a contracted state pressers 9, the holding unit 3 fitted with a retainer 9 is pressed towards the boundary 4, the distance between the holding portion 3 and the boundary portion 4 becomes smaller. At this time, the distance is adjusted to be smaller than the diameter of the ball 12. Pulling the holding member 9 but this distance ing larger, at this time the distance is kept by adjusting the elasticity of the size and retainer 9 of the holder 3 as greater than the diameter of the ball 12.

  A thread was used for attachment, and both ends 10A of the presser 9 were sewn and attached to the frame 2, and two places (10B) near the center were attached to the net of the holding part 3. There is no problem even if it is attached by a method other than sewing, for example, a method such as adhesion. Moreover, even if it is the partial mounting | wearing which mounts the place of 10A and 10B like a present Example, the method of mounting | wearing entirely may be sufficient.

In this embodiment, the presser 9 is mounted on the outer side (upper side in the drawing), but may be mounted on the inner side (lower side in the drawing) or may be mounted so as to be sandwiched by the holding unit 3. Good. As the mounting portion, the holding portion 3 on the upper surface portion of the boundary portion 4 is suitable .

However, when mounting or using them, the distance between the boundary portion 4 and the holding portion 3 is larger than the diameter of the ball 12 during collecting or carrying (that is, when the presser 9 is not pulled). The distance is adjusted so that the distance becomes larger than the diameter of the ball 12 so that the distance becomes smaller. Of course, the holding portion 3 on the upper surface portion of the ball collecting portion 5 is sized so that an appropriate amount of balls can be collected and held there.

  Hereinafter, the usage method of the ball-collecting tool 1 of a present Example is demonstrated.

At the time of collecting the ball, the handle 8 is held, and as shown in FIG. 5, if the ball collecting portion 5 is put on and pressed from the ball 12 on the floor, the ball passes between the linear objects 7. The ball is moved from the floor surface toward the holding unit 3 and collected. At that time, the presser 9 is not pulled and is kept as it is. In that state, as shown in FIGS. 2 and 4, the presser 9 presses the holding portion 3 so that the distance ( space ) to the boundary portion 4 is smaller than the diameter of the ball 12. The balls 12 in the holding unit 3 are reliably collected and held without fear of spilling out toward the ball discharging unit 6.

  At the time of ball discharge, for example, when it is desired to move the ball 12 to the container 13, as shown in FIG. 6, the tip 9 (left end in FIG. 6) of the ball collector 1 is slightly raised upward to hold the presser 9. Is pulled upward (in the direction of arrow G in FIG. 6), a space is formed between the boundary portion 4 and the holding portion 3 so that the ball 12 can pass, and the ball 12 moves toward the ball discharging portion 6 through the space. Drop into the container 13. In order to create a space through which the ball 12 can pass, a retainer 3 having a predetermined stretchability is used, and the holding portion 3 has a size capable of forming such a space.

  As described above, the presser 9 that expands and contracts is attached to the holding portion 3 on the upper surface portion of the boundary portion 4. As a result, the ball 12 is smoothly held without being spilled toward the draining portion 6 during the ball collection. I can do it now. There is no spillage when carrying. Further, when the ball 12 is to be discharged, it is discharged by a simple operation by simply pulling the presser 9 upward, and it is a very easy to use ball collecting tool.
