Building panel positioner

A building panel positioner for use in applying ceiling or wall board or panel to a framework in building construction comprising:

• a. a base having wheels to facilitate positionment thereof;
• b. an elongated hollow upright bottom section secured at one end thereof to said base;
• c. an elongated tubular intermediate section mounted for telescopic movement inside said base section;
• d. an elongated inner top section mounted for telescopic movement inside said intermediate section;
• e. support means secured to said top section for containing thereon the board or panel during positionment relative to the framework, said support means including four substantially equally spaced support arms extending outwardly from said top section to define a planar support surface;
• f. retaining means for preventing lateral movement of the board or panel relative to said support means in a given direction, said retaining means including a vertically extending finger associated with at least two of said adjacent support arms at substantially one end thereof positioned above the support plane, such that lateral movement of the board or panel on the support plane in the direction of said retaining means is prevented;
• g. means for vertically adjusting said sections relative to each other for raising or lowering a wall board or panel positioned on said support means in place for securment to the framework;
• h. said vertically adjusting means includes a compressor, an electric motor for powering said compressor, and a switch electrically connected to said electric motor, such that when said motor is energized the compressor is actuated to raise and lower said sections;
• i. locking means in operative relation with said retaining means on two of said adjacent support arms to be adjusted to a position in spaced relation to said support arm and in partially overlapping relation to the board or panel, such that outward movement of the board or panel from the support plane is prevented;
• and
• j. said locking means includes:
• i. a locking member pivotally secured at one end to the upper end of said finger,
• ii. means for securing said locking member in releasably fixed position and in overlapping relation to the board or panel,
• iii. mating surfaces on said locking member and said finger for engagement with each other, and
• iv. said securing means includes a fastener extending between said locking member and said finger which when tightened will retain said mating surfaces in fixed position.
