Abstract: A device, for supporting a heavyweight panel in a curtain wall unit or partition having a rectangular frame, comprises a horizontal support plate adapted to support the panel at its lower edge thereof, and a vertical plate extending downwardly and centrally from the horizontal support plate. At least one projection is disposed on the underside or upper side of the horizontal support plate adjacent to an interior edge thereof for being fitted in at least one opening in an interior part of a lower horizontal frame member. The device also may have a plurality of parallel first reinforcing ribs on an interior face of the vertical plate and a plurality of parallel second reinforcing ribs on an exterior face of the vertical plate.

Abstract: A modular mezzanine structure for ready attachment to preexisting storage cabinet structure is disclosed. Angle brackets attached to supporting feet are provided. The feet are inserted into apertures conventionally formed in the cabinets. Platforms may then be assembled upon the angle brackets. A stairway and landing may similarly be attached to the cabinet structure for providing ready access to the platform thereof.

Abstract: A collapsible building which is mounted on the platform of a conveyance has a first elongated unit which is mounted on the platform, and a pair of collapsible elongated units which flank the first unit when the building is fully erected. Each collapsible unit has a base portion including a floor and sidewalls, and a separable roof. The roof is connected to the respective base portion by two pairs of links at the front and rear ends of the respective collapsible unit and each base portion is pivotable relative to the first unit about a horizontal axis extending along the respective side adjacent to the bottom of the first unit. The links compel the roofs to move relative to the respective base portions when the base portions are pivoted by hydraulic motors between upright positions adjacent to the respective sides of the first unit and second positions in which they confine of the first unit.

Abstract: An insert retainer for securing a door insert such as a window or screen unit within the door frame and comprising a one-piece flexible strip having a generally flat first web portion, a second web portion which extends from one end of the first web portion perpendicular thereto, a third web portion forming a channel with the first and second web portions, an arcuate integral hinge forming an extension of the second web portion, and an end portion extending outwardly from the integral hinge at an acute angle to the second web portion. The angularly extending end portion is arranged to be tightly received within a channel formed in the storm door and thereby compress the integral hinge about a bead forming a part of the channel construction. The invention also deals with an improved storm door including the new insert retainer.

Abstract: A platform trestle adapted for assembly or disassembly with similar platform trestles to form stages for public events is provided with an upper platform, an upper and a lower frame, and four scissor members, the platform trestle being manually adjustable as to height. All of the scissors are arranged side by side and respectively two of the scissors by pairs of respectively an outer and an inner scissor member at the longitudinal sides of the platform. Moreover the legs and the arms of the outer and of the inner scissors are strutted by cross bracings so that the platform trestle is very stable, but still portable by two persons and is adjustable at a maximum height just under the length of its platform.

Abstract: A plate-like ground or earth anchor has a scoop-like channel formed in the leading end thereof, and an open topped socket formed in the trailing end thereof, laterally extending wings along the length thereof, and a raised cable anchor ridge directing dirt from the channel so that a cable or rod secured therein will be free to swing when it is tensioned to pull the plate from an upright driving position to a transverse horizontal locking position. The leading ends of the wings are beveled toward the channel to cooperate therewith for forming a chisel-like leading edge on the plate. The open top of the socket is inclined to provide an apex beyond the wings and a cutting edge merging into the rear ends of the wings which are also beveled to provide cutting edges. The plate is driven upright into the ground by an impact rod loosely fitted in the socket and as it cuts into the ground, it leaves a channel or groove for a cable or tension rod.

Abstract: A slotted standard adapted to receive a shelf bracket or the like is fastened to a metal stud having a longitudinal channel defined by the fingers of a furcated extension of the sutd's web. The walls of the channel are either threaded or threadable to receive a screw which passes through the standard and fastens the standard to ledges on both sides of the channel opening. When placed in a partition, the stud serves as an anchor for the standard so that a bracket may be attached to the standard in order to support a shelf, a piece of furniture or the like.

Abstract: An improved arrangement of so-called upper and lower curbs with interposed springs having an interconnected condition allowing for their delivery to an installation site as a single unit, and at said site being readily released from each other to then allow vibratory movement in said upper curb relative to said lower curb on said interposed springs, and wherein the release is produced by the force urgency in the springs which dampen the vibration of the air handling unit which is mounted on the curbs.
