Abstract

A hermetic closing door, characterized in that it comprises a sliding panel that has coupled upper rollers that rotate on horizontal axes destined to slide along upper guides, which are provided with extreme ramps in the area corresponding to the opening itself, allowing the vertical descent of the sliding panel in said closing position to adjust at the edges of the frame, provided with sealing profiles and also having said sliding panel, an elastic profile at its lower edge intended to provide the necessary airtightness in correspondence with the edge smooth bottom of the opening. 2. A sealing door according to claim 1, characterized by having at the lower edge of the sliding panel, an oblique guide groove into which are fixed lower rollers also oblique, which are intended to guide inferiorly to the panel of closing of the door. 3. A sealing door, according to claim 1, characterized in that it is coupled on the vertical closing edge, a door opening lever provided with an extreme handle and coupled to a fixed bushing on the edge of the door, prolonging the lever in a fixed arm capable of acting against the edge of the door frame, producing the opening thereof. 4. A sealing door according to claim 1, characterized by the arrangement on the vertical edge of the frame on which the door is adapted, in the closed position, of a long lever coupled with rotational capacity to an intermediate bracket, rotating in turn on an axis perpendicular to the edge of the door frame, said lever being provided with an intermediate projection to exert the opening force from inside it.
