[0005] In the past, golfers had to repeatedly bend over and bend their knees to catch balls scattered on the ground. The more balls they had to catch, the greater the burden on golfers, so a way to reduce the amount of work was needed. In response to this, the above-mentioned prior art can reduce the effort required to bend over, etc. However, on the other hand, the prior art (Patent Document 3 and Non-Patent Document 7) that is assumed to be similar to the present invention has issues remaining, such as reducing abrasions caused when balls are collected by a machine and the ease of use when removing balls from a basket.

[0006] (1) The number of springs and the gap size were adjusted. The spring attached to the bottom opening of the cage must press the cage down on the balls, which are about 42.67 mm in diameter, and smoothly take the balls into the cage through the gap in the spring. At the same time, it must also have the function of holding the balls without letting them fall. In order to ensure that these functions are realized, the inventor carefully adjusted the number of springs and the gap between the springs as variables. As a result, it was found that the optimal combination of five springs and a gap between the springs of 40 mm (claim 1) is when the cage has a ball storage capacity of 30 balls and the bottom opening is 130 mm high and 185 mm wide. (2) It is now easier to take out the ball In the above prior art survey, golfers had to grab the balls one by one when they wanted to remove them from the basket. If there are a large number of balls to be collected, this leads to a waste of time and effort. The inventor has devised a structure in which the top of the basket is made an opening, and the balls can be removed by tilting a stick attached to the basket. In addition, one of the four side panels of the basket is inclined outward at 23 degrees (claim 2). There is no problem if this angle of inclination is slightly different, but if the inclination is too large, the balls may roll out of the opening on the top of the basket when the collector is transported. On the other hand, if the angle of inclination is smaller than this, the basket needs to be tilted significantly to remove the balls. The inclination angle of 23 degrees is the result of finding a combination of these advantages and disadvantages. Effect of the Invention

[0007] In this invention, by placing a spring of the dimensions specified in claim 1 at the bottom opening of the basket, the balls can be collected smoothly without being scratched, and a maximum of 30 balls can be securely accommodated in the basket. In addition, by adding an inclination to the side of the basket as in claim 2, it became possible to take out the ball by just tilting the stick slightly. These inventions further reduced the effort required by golfers and improved the efficiency of play. [Brief description of the drawings]

[0009] The components of this device are the basket part and the cane part. A commercially available walking stick was used for the cane part. The basket has six sides, with the top (130mm long x 310mm wide) and bottom (130mm long x 185mm wide) open. A piece of wood is attached to the top for attaching the cane. Five springs are attached to the bottom, in parallel and at equal intervals, at the opening. Claim 1 specifies that the gap between the springs is 40 mm, with the ball having a diameter of approximately 42.67 mm. In claim 2, one of the cage bottom surfaces is specified to be angled 23 degrees outward from the cage. EXAMPLES

[0010] The embodiment will be described with reference to the attached drawings. 1 to 4 are the four sides of the cage. The materials and dimensions of 1 to 4 are as follows: 1 Right horizontal board: Cedar board (top 310mm, bottom 185mm, height 125mm, thickness 12mm) 2 Left horizontal board: Cedar board (top 310mm, bottom 185mm, height 125mm, thickness 12mm) 3 Front panel: Galvanized steel plate (180 mm long, 130 mm wide, 0.4 mm thick) 4 Rear panel: Galvanized steel plate (145 mm long, 130 mm wide, 0.4 mm thick)

[0011] The cane 5 is fixed to the center of the opening on the top of the cage by the top plate 6. The materials and dimensions of 5 and 6 are as follows: 5. Stick: Carbon steel pipe (length 740 mm, outer diameter 16 mm) 6 Top panel: Cedar board (15mm long, 45mm wide, 12mm thick) Incidentally, number 5 uses a commercially available walking stick with a handle attached to a round bar, but it is not necessary to have a handle.

[0012] Five springs 7 are attached in parallel to the opening at the bottom of the cage. The gap between each of the five springs 7 is 40 mm. The material, dimensions and specifications of 7 are as follows: 7 Spring: Stainless steel (wire diameter 1.4 mm, outer diameter 10 mm, spring length 104 mm), equivalent to Yawata Screw Co., Ltd. pull spring (product number E672, maximum load 5.5 kg, maximum extension length 151 mm) [Industrial Applicability]
