Claims

[Scope of utility model registration request]

The door stop body is equipped with two hydraulically actuated cylinders that communicate through an orifice at the cylinder end, and one of the cylinders has a piston front face protruding outside the door stop body to accommodate immovable parts such as the vertical frame of the opening frame. A working fluid is sealed between the cylinder chambers on the front surface of the piston in the other cylinder, which communicates with the cylinder chamber on the front surface of the piston in the other cylinder through the orifice. The piston of the cylinder is equipped with a compression spring on the back so as to bias the piston in the direction of pressing the working fluid, and the door stop main body is fixed to the shoji.
