Hydraulic atuator device for raising and lowering a seat and lid
First Claim
1. A hydraulic drive device for raising and lowering the covering lid and seat of a toilet, comprising a left module and a right module, said modules attached together, where each said module has the same configuration, said module configuration characterized by:
- a casing;
a central transverse shaft contained within said casing, and the end of which protrudes from said case, and wherein each said casing is internally divided into three semicircular cavities;
said left shaft end is attached to the toilet lid and the right shaft end attached to the toilet seat, the opposite end being fixed to a drive plate for three flaps, with one of each said flap being housed in one of each said recess of said casing;
in each said recess is also housed a cylindrical diaphragm adjoining each of said flap,whereby when said diaphragms are filled with water, said diaphragms press said flaps simultaneously, thereby causing a partial rotation of said shaft, the left said shaft being coupled to the lid and the right said shaft being coupled to the seat lift the lid and seat together or separately,or said lid and seat together or separately are folded down when said water is discharged from said diaphragms through a check valve;
said diaphragms being connected and fed through a check valve adapted firstly to allow the supply water to fill the diaphragms when a respective floor valve located on the floor to the left or right side of the toilet is actuated by hand or foot, and each said check valve adapted secondly to discharge water and empty said diaphragms through a duct into the tank of the toilet when the toilet flush button is actuated for discharge thereof, said left and right valves being connected to a general water supply distributor and said supply distributor being connected to the water supply duct of the supply network that feeds the toilet tank.

Abstract
Improvements to a hydraulic drive device for raising and lowering the lid and seat of toilettes, characterized by a left and right modules comprising a casing with a central transverse shaft whose ends protrude, each said casing is divided into three recesses; the left shaft end is attached to the lid and the right shaft end to the seat, the opposite end of each shaft being fixed to a drive plate of three flaps, one of each flap housed in each recess of the casing, with each recess also housing a cylindrical diaphragm, which when filled with water press simultaneously against the flaps to cause a partial rotation of the shafts, to raise or lower the lid and seat together or separately by rotary displacement; said diaphragms are fed through a check valve that allows the passage of feed water to fill the diaphragms and to discharge the water from the diaphragms through a duct into the toilet tank when the toilet flush button is actuated; the left and right floor actuation valves are connected to a general water distributor element connected to the water supply duct.
