Adjuster for frame of doorway during installation

摘要

The adjuster has a firm-standing rectangular frame (13) which is composed of vertical profiles (2) similar to but shorter than the vertical parts of the door's frame. They are combined with horizontal profiles at the top and bottom (5,7), also similar to but shorter than those of the door's frame, or are else are extensible, specifically by being telescopic, and additionally fitted out with frame wall or floor fixers such as height adjustable feet (18). The door's frame is held in place by releasably or adjustably fitted holders (46) and adjustment end stops (45) assisted by a spirit level (27). The adjuster frame can be adjusted over its depth parallel to the wall thickness, and be constructed from two exactly registered rectangular frames (10,11) joined in parallel planes by spacers (12) of equal length. These spacers can be telescopically extended at right angles to the frame using infinitely arrestable adjuster parts (5,7,14,16). The frame is located by a lintel-level clamp (29) which swings round within the opening (39) produced by the completed adjuster frame, using a self-arresting contact plate (30) working at right angles to the main plane of the frame. The frame is preferably made of steel or stable plastics.
