There is disclosed a ventilator for use with windows, doors, or other building hardware. The ventilator includes an inner plate having air vents and an outer plate spaced apart from the inner plate in the transverse direction of the ventilator and providing an opening displaced from the air vents. Provided between the inner and outer plates are a filter and a partition extending from the inner plate toward the outer plate until it abuts against the filter. The partition is adapted to direct a flow of air from the opening to the air vents at least twice through the filter. The ventilator is prefabricated as a unit and is easily installed within the windows, doors and the like.

Ventilator

A ventilator, constructed to serve as a horizontal rail in a building component, includes a pair of spaced apertured plates, the aperture of one being an air inlet vertically spaced below that of the other which is an air outlet, and filter and baffle means disposed in the path between said apertures, and so arranged that an air current flows through the filter at least twice.

A post of uniform cross sectional shape for installation uprightly on the outside of a balustraded window or the like for use as one of the supports of the balustrade. The post includes a pair of opposite side walls each having an undercut groove formed lengthwise thereon. A pair of brackets of identical construction are provided separately, each comprising a mounting plate at one end and a pair of clamping jaws at the other end for engaging the post therebetween. The mounting plates of the brackets can be screwed to the window frame, and the post engaged between the clamping jaws of each bracket is connected thereto by a bolt inserted into and through a hole in each jaw and secured by a nut received in one of the undercut grooves of the post.

Adjustable-height post assembly for ready installation on a window frame

A balustrade having a series of balusters connected to both top and bottom rails or, if desired, to a top rail only is disclosed which can be completed by assembling standardized parts. The top and bottom rails each includes a horizontal baluster mounting plate facing inwardly, and this mounting plate has an aperture extending along one of the longitudinal edges thereof and a series of longitudinally spaced recesses open to the aperture. The end portions of the balusters are inserted into the respective recesses of the mounting plate, either directly or via the aperture. Means are provided in several forms of construction for locking the baluster end portions within the recesses. The aperture can be closed by a separate filler plate, which is adaptable either to snap into position in the aperture or to slide longitudinally therein.
