PROBLEM TO BE SOLVED: To provide a sand pool leveler which properly bites into a sand pool during leveling work on sand, which makes a useful life long, and which facilitates replacement.SOLUTION: A sand pool leveler body 1 has upper and lower ends of the rectangular body 1 formed in an uneven shape 2. A longitudinal section is subjected to bending 3 in a "dog-leg shape" in the center. Each plane subjected to bending 3 is provided with attachment holes 4, 4, 4 and 4. Additionally, the uneven shape 2 assumes a saw blade shape, and its tip is sharp. A cut of a saw blade becomes gradually shallow near both the ends, and the upper and lower ends are notched to a bent central side.SELECTED DRAWING: Figure 7
【課題】本発明は砂上の均し時の砂場への食い込みを良好にすると共に、使用寿命を長くし、交換も容易とした砂場の均し具を提供せんとする。【解決手段】砂場の均し具の本体１は、矩形の本体１の上下端部が凹凸形状２に形成され、縦断面が「く字状」に中央で折曲３している、当該折曲３した各平面に取付用孔４、４、４、４を設けてある。また、凹凸形状２は鋸刃形状で先端が尖っており、両端近傍では鋸刃の切り込みが徐々に浅くなって、上下端部が折曲した中央側に切欠いてあるように成っている。【選択図】 図７
