发明名称 Level indicator for a wall-mounted fixture
摘要 A device is provided for leveling a wall-mounted fixture such as a picture frame. The device has a mounting element, which can be fastened to a back surface of the fixture at a suitable location, such as a corner. A retractable level formed of multiple telescoping cylinders is mounted with the mounting element. The level is movable between a hidden position and a viewing position. In the hidden position the level is retracted into a recess in the mounting element so that the level is substantially hidden from an observer viewing the fixture. In the viewing position the level is extended outwardly from the mounting element for use in leveling the fixture.
