A method for levelling an anchoring system for a dropped ceiling, a floating floor, a pipe or a cable tray, having at least one support bracket for the pipe or a section bar of a support frame of a dropped ceiling, a floating floor or a cable tray, and an adjustment screw to adjust the distance of the section bar from a reference surface, wherein a laser receiver is placed in contact with the section bar or the support bracket, has an optical window to receive a laser beam emitted by a laser level, assumes two height states indicating the receiving position of the laser beam relative to a reference position, and transmits, in a wireless manner, two control signals corresponding to the two height states, and wherein an electric screwdriver receives, in a wireless manner, the control signals and switches the rotation of the adjustment screw between one direction and the opposite direction based on the control signal received.

A reliable swiveling fastening mechanism that allows a plate to be horizontally, obliquely and vertically fastened comprises, in the position of use: a vertical supporting profile to be arranged at the top of the mast, coaxially to the mast; two parallel backing plates mounted so as to swivel on the supporting profile and interconnected on one side by a plate carrier fastening component and on the other side by a U-shaped vertical position stop attached to the backing plates and arranged in such a way that the plate carrier fastening component is parallel to the supporting profile when the supporting profile is in contact with the vertical position stop; and a retractable stop supported by at least one backing plate so that the plate carrier fastening component forms an angle between 10° and 80° with the supporting profile when the supporting profile is in contact with the retractable stop.

A sheetrock lifting device including a base with a protrusion centrally disposed on a front side of the base. A plurality of locking caster wheels is disposed on the base and on the protrusion. A pair of stanchions is used to house a battery and a manual wench. A pair of support rods supports the device by connecting the stanchions to the protrusion. A pair of stabilizing beams further supports the stanchions. A pulley device containing a pulley arm, pulley, and pulley cable is disposed on the stabilizing beams. An electric wench is disposed between the stabilizing beams and is in operational communication the battery. The electric wench raises and lowers a telescoping tube to which is attached a drywall frame. A manual wench alternately raises and lowers the telescoping tube with a cable hook connected to a ring on the telescoping tube.

A photovoltaic (PV) panel mounting system for a vehicle includes: a PV panel movably mounted on a vehicle panel; a first electrode electrically connected to the PV panel; a second electrode attached to the vehicle panel and electrically connected to the first electrode; and a damping mechanism elastically supporting the PV panel with respect to the vehicle panel. The damping mechanism allows the PV panel to move between a first position and a second position. The first position refers to a position in which an outer surface of the PV panel is flush with an outer surface of the vehicle panel and the second position refers to a position in which the outer surface of the PV panel is recessed from the outer surface of the vehicle panel.

A multi-use support stand used for holding various types of building materials and used in other types of construction projects. The support stand includes a horizontal foot brace and a horizontal cross brace attached to a bottom of a vertical support post. An oblique support post is attached to a top portion of the vertical support post and a portion of the foot brace. One end of a horizontal extension arm is attached to a sliding “U” shaped channel. The channel is received around a portion of the oblique support post. A pin is received in a selected pin hole in the side of the support post for securing the sliding channel to the oblique support post. When a first and second support stands are placed next to each other, the horizontal extension arms are used for holding loads of sheet rock, plywood, bench table top, working platform, shelving, footbridge sections, dimensional lumber, and other application specific items needing to be supported horizontally or an elevated obtuse angle.

An end effector including: a supporter configured to support a plate member; a support table provided at an end portion of the supporter via an universal joint and configured to support the plate member by making surface contact with the plate member; holding unit including a pair of holders configured to move linearly in a planar direction while the support table is interposed between the pair of holders in the planar direction, the holding unit being fixed to a base portion of the support table; and electric cylinders configured to change an inclination angle of the support table with respect to the supporter.

A method for levelling an anchoring system for a dropped ceiling, a floating floor, a pipe or a cable tray, having at least one support bracket for the pipe or a section bar of a support frame of a dropped ceiling, a floating floor or a cable tray, and an adjustment screw to adjust the distance of the section bar from a reference surface, wherein a laser receiver is placed in contact with the section bar or the support bracket, has an optical window to receive a laser beam emitted by a laser level, assumes two height states indicating the receiving position of the laser beam relative to a reference position, and transmits, in a wireless manner, two control signals corresponding to the two height states, and wherein an electric screwdriver receives, in a wireless manner, the control signals and switches the rotation of the adjustment screw between one direction and the opposite direction based on the control signal received.

A user attachable overhead panel support device for positioning a panel for attachment to an overhead substrate includes a harness that is configured to position on and to couple to a torso of a user. Each of a pair of shoulder straps of the harness is positioned over a respective shoulder of the user. A pair of posts is coupled singly to the pair of shoulder straps. The posts are substantially parallel and substantially vertically positioned when the user is uprightly positioned. Each of a pair of plates is coupled to an upper end of a respective one of the pair of posts. The pair of plates is configured to support the panel overhead, enabling the user to position the panel in abutment to the overhead substrate. Hands of the user remain free for fastening the panel to the substrate.

A drywall installation support apparatus for one man ceiling drywall installation includes a main panel having a main top side, a main bottom side, a main front edge, a main back edge, a main left edge, and a main right edge. The main left edge and the main right edge has a channel extending therethrough. The main top side has a pole aperture extending through the main bottom side. The pole aperture is configured to receive a tip of a paint pole. A pair of wing panels is slidably coupled within the channel of the main left edge and the main right edge. A distance between an outer edge of each wing panel defines an adjustable length of the apparatus.
