Title:
DEPTH ADJUSTING POOL EQUIPMENT
Document Type and Number:
Japanese Patent JP3917802
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide depth adjusting pool equipment capable of quickly, simply and easily adjusting the depth of a pool by reducing a dead space under a variable floor.
SOLUTION: The depth adjusting pool equipment includes the variable floor provided so as to make it possible to rise and fall in the pool and a buoyant tank provided inside of a variable floor frame as the lower part of the variable floor in the lower surface of the variable floor, the variable floor is raised and lowered by varying buoyancy of the buoyant tank, the variable floor is locked to constitute the depth from the water surface of the pool to the upper surface of the variable floor in an optionally set manner, the rising and falling itself of the variable floor is made by the variation of the buoyancy of the buoyant tank inside of the variable floor frame, the variable floor is locked at the position to simplify the rising and falling mechanism of the variable floor, and the dead space under the variable floor is reduced to the minimum. The depth adjustment of the pool is quickly and easily made, and operating and utility costs are reduced.
