An access door for installation in a rough opening formed in a building ceiling or wall including an outer framework having an opening adapted to be fitted in the rough opening and secured to the ceiling or wall, a cover for opening and closing the opening in the outer framework, and link hinges for pivotally connecting the cover to the outer framework, whereby when the cover is released, the cover has imparted a vertical descent movement thereto. Rapid opening and closing pivotal movement of the cover by gravity is controlled, and the opening angle of the cover can be made great.
A cremorne lock mounting device for a window is capable of reducing width dimension of a frame of a window door and thus provide greater lighting area. A hollow portion extending over a frame body of the frame of the window door and a panel support portion is defined. A lock body of the cremorne lock is mounted within the hollow portion. Thus, the frame body is required smaller width dimension than a width dimension of the lock body.
An access door to be installed on the ceiling or the like of a building which essentially comprises an outer square frame adapted to be installed in an opening formed at said installation area; an inner square frame pivotally connected to said outer frame for movement between open and closed positions; a pair of link hinge means provided on each of two selected sides of said outer frame to pivotally connect said frame to said outer frame; and a lock means for locking said inner frame to said outer frame as the inner frame is in its closed position. The inner frame has a joint finishing flange at the peripheral edge thereof to conceal the peripheral edge of said outer frame as the inner frame is in its closed position. Also, each of the link hinge means essentially comprises a pair of parallel long links in which the leading end of the lower link has a swing control arm, a short follower link for pivotally connecting the leading ends of the long links, a link guide upwardly pushing the swing control arm as the inner frame is closed, and a bracket connecting the long links together and securing the link hinge means to the outer frame.
In a window for installation in an inclined roof (1) the main frame (2; 3) includes a top-hinged upper window frame (12) and a bottom-hinged lower window frame (4) to be opened outwards into horizontal and vertical positions to form a shedroof above and a breast wall of a balcony-like enlargement. The lower frame (4) is hinged to the main frame (2; 3) in such a manner that its bottom section (4') in the open position is displaced downwards from the bottom section (2 ) of the main frame to reduce the height of the top edge of the frame above the latter bottom section.
A method for making an articulatable window assembly suitable for use as a side window or a rear lift gate window of a vehicle includes providing a curved tempered glass sheet and at least one mounting member for attachment to the glass sheet. At least one layer of primer is applied to a portion of the inner surface of the glass sheet. A flange of an attachment portion of the mounting member is maintained positioned offset from the primed portion of the inner surface of the tempered glass sheet and with a viscous adhesive disposed therebetween for at least a time period sufficient for the viscous adhesive to achieve an at least partial cure. The offset distance between the flange of the attachment portion of the mounting member and the primed portion of the inner surface of the glass sheet is greater than 0.1 mm and less than 3 mm.
