The mounting frame of the present invention is constructed for being easily installed in the wall of a building from the exterior side of the wall using only a simple hand tool, such as a screwdriver, and for slidingly receiving a ventilator in a quick and simple installation procedure. The mounting frame has an outwardly extending peripheral flange on the front thereof which is adapted to engage the exterior face of the wall, and includes clamping means extending rearwardly of the peripheral front flange for engaging the interior face of the wall and clamping the frame in place in the wall. Inwardly extending flanges on the top and bottom walls of the frame are provided for engaging the rear of the ventilator to limit rearward movement of the ventilator. The ventilator may be slidingly positioned in the opening formed by the frame and held in place with the rear of the ventilator engaging the inwardly extending flanges and with opposite ends of the ventilator being slidingly positioned behind the side walls of the frame to limit forward movement of the ventilator and thus hold the ventilator in place in the opening.
A ventilator and mounting frame assembly constructed for quick and simple installation in a wall of a building and comprising a frame adapted to be mounted in the building wall from the exterior side of the wall, said frame comprising respective opposing pairs of interconnected generally horizontal and generally vertical walls defining an opening of predetermined size, and said frame having an outwardly extending peripheral flange at the front thereof adapted to engage the exterior face of the wall and having clamping means extending rearwardly of said peripheral flange for engaging the interior face of the wall and clamping the frame in place in the wall, a ventilator positioned in the opening of said frame, respective abutment means carried by one of said pairs of walls and extending inwardly into said opening and engaging the rear of said ventilator to limit rearward movement of the ventilator, said abutment means being located rearwardly of the other of said pair of walls and said ventilator being slidingly positioned in the opening with opposite ends of the ventilator located behind said other walls for engaging and limiting forward movement of the ventilator and thus holding the ventilator in place in the opening.
A ventilator and mounting frame assembly constructed for quick and simple installation in a wall of a building and comprising a frame adapted to be mounted in the building wall from the exterior side of the wall, said frame comprising interconnected generally horizontal top and bottom walls and generally vertical side walls defining a rectangular opening of predetermined height and width, said frame having an outwardly extending peripheral flange at the front thereof adapted to engage the exterior face of the building wall and including clamping means extending rearwardly of said peripheral flange for engaging the interior face of the building wall and securing the frame in place in the wall, a pair of opposing inwardly extending flanges carried respectively by said top and bottom walls and located rearwardly of said side walls and extending inwardly into the opening of said frame, and a ventilator having a rectangular grille of a height corresponding to the height dimension of said opening and of a width greater than the width dimension of said opening, the rear surface of said grille engaging said inwardly extending flanges for limiting rearward movement of the ventilator, and opposite end portions of said grille being slidingly positioned behind said side walls for engaging and limiting forward movement of the ventilator and thus holding the ventilator in place in the opening.
A mounting frame for a ventilator constructed for quick and simple installation of the ventilator in a wall of a building from the exterior side of the wall, said frame comprising respective opposing pairs of interconnected generally horizontal and generally vertical walls defining an opening of predetermined size, said frame having an outwardly extending peripheral flange at the front thereof adapted to engage the exterior face of the building wall and having clamping means extending rearwardly of said peripheral flange for engaging the interior face of the wall and clamping the frame in place in the wall, respective abutment means carried by one of said pairs of walls and extending inwardly into said opening and adapted for engaging the rear of a ventilator positioned in the opening to limit rearward movement of the ventilator, and said abutment means being located rearwardly of the other of said pairs of side walls a sufficient distance to permit the ventilator to be slidingly positioned in the opening with the rear of the ventilator engaging said abutment means and with opposite ends of the ventilator located behind said other walls to limit forward movement of the ventilator and thus hold the ventilator in place in the opening.
A mounting frame for a ventilator constructed for quick and simple installation of the ventilator in a wall of a building from the exterior side of the wall, said frame comprising interconnected generally horizontal top and bottom walls and generally vertical side walls defining a rectangular opening of predetermined height and width, said frame having an outwardly extending peripheral flange at the front thereof adapted to engage the exterior face of the building wall and including adjustable clamping means extending rearwardly of said peripheral flange for engaging the interior face of the building wall and securing the frame in place in the wall, a pair of opposing inwardly extending flanges carried respectively by said top and bottom walls and located rearwardly of said side walls a sufficient distance to permit a ventilator to be slidingly positioned in the opening with the rear of the ventilator engaging said opposing inwardly extending flanges and with opposite end portions of the ventilator located behind said walls to thus hold the ventilator in place in the opening.
