Simple Shoe-Drying Machine

The horizontal bars are usually firmly placed in the playground or park and the lowest height is about 155 cm (5.1 ft.). For kids, it is difficult and insecure to use it themselves. Once when I was exercising in the park, I saw the parents holding and raising the kids up to reach the horizontal bar, the distance from the ground is at least 30 cm, it could cause a danger if the parents carelessly loose the hands or the kids jump down accidently. For protecting kids’ safety and using it fewer limitations, I invent The Simple Horizontal Bar which is adjustable, moveable and storable.
