MOVING BOTTOM FOR POOLS OR RECESSES Russian patent published in 2019 - IPC E04H4/06 E04B1/24 

FIELD: satisfaction of human vital requirements.

SUBSTANCE: invention relates to a movable bottom for a pool or recess, intended for installation in this recess and moving parallel to its main plane. In the method, the movable bottom device for pools or recesses comprises a frame attached to a trellis framework comprising first profiles extending in a first direction and belonging to at least one first plane P1, called the top plane, and the second profiles, overlapping with the first profiles and extending in the second direction, preferably perpendicular to the first direction, and belonging to second plane P2, called the lower plane, different from said first plane P1, as well as devices for raising and lowering the frame and framework and driving means of the devices for raising and lowering, characterized in that the said first and second profiles have a U-shaped cross section having a first side and a second side parallel to each other and connected by a third side having a height H, moreover, the first side and the second side contain holes, grouped in a sequence along the length L of the profile, each of the sequences contains the first row of N1 holes aligned and equidistant from each other at distance d1, this row is followed by the second row of N2 holes aligned and equidistant from each other by distance d2 exceeding said distance d1, and the third side contains two rows of holes N1, aligned and equidistant by distance d1, located opposite the holes of the first and second sides, and a hole extended along the height H and surrounded by at least four holes aligned with two rows of holes; each of the edges of the profile contains holes on each side, with these profiles are bolted together.

EFFECT: technical result is the provision of a device made with the possibility of quick assembly and commissioning, which can be easily adapted for pools or recesses of different shapes and sizes.
