Abstract:
An extruded aluminum window is provided with outer frame members for fastening to the building and inner frame members for fastening and holding one or more glass panes. The frames are provided with a sealing system which while allowing pressure equalization prevents air and moisture from passing into the interior of the structure when the window is closed. The sealing system includes an external water deterrent and a pair of internal sealing members with the frame between the external deterrent and the internal sealing members having a water barrier formed with a plurality of serrations each in a plane parallel to the frames. The sill of the outer window frame is provided with internal and external upwardly extending legs, and a raised central portion which joins the external leg in a recessed gutter to drain water out through slots in the external leg. In one embodiment the window can pivot a full 180.degree. with seals being provided to prevent air from leaking through the pivot connections when the window is closed. A glazing bead is provided with legs which can snap into the outer window frame offset from the plane of the glass and at its other end forms a snap-in seal as part of the internal sealing means. In one embodiment the internal frame can be pivoted 180.degree. with a self-latching lock holding the movable frame in an open cleaning position.
Abstract:
The invention concerns a window specially designed for emergency use. The window comprises a fixed outer frame (1) and a sash (2) mounted for normal horizontal pivoting movement between open and closed positions about axis Y--Y. Two arms (3) extend in the respective side rebates between the frame (1) and sash (2), and opposed horizontal pivots (6) are secured to the sash (2) and the arms (3) for such normal pivoting movement of the sash (2). Each arm (3) is connected to the top (1a) of the frame (1) by a hinge (4) and each arm is acted on by a respective telescopic gas spring (5) confined within the rebate but acting on the associated arm (3) to urge it outwardly of the frame (1). For normal opening and closing movement of the sash (2) for which a casement fastener (7) is fitted, the arms (3) are retained secured to the frame (1) by a catch arrangement that is operable manually by a control handle (8) separate to the fastener (7). For emergency opening of the window, the control handle (8) is actuated and the catch means is released to disengage the lower ends of the arms (3) so that the forces applied by the gas springs (5) act on the arms (3) causing the arms to move outwardly of the frame (1) about the hinge axis Z--Z carrying the sash (2) outwardly clear of the opening of the frame (1) for emergency access. Special features for automatic re-engagement of the catch means and control of the system are described in detail. The invention has particular application for roof windows.
Abstract:
A hinge primarily for a roof window with a pivotally opening sash comprises a body to be fixed to the frame of the window, a support member pivoted to the body and arranged to be secured to the sash, a stay member pivoted to the support member spaced from its connection to the body, and constraining mechanism comprising a frictional assembly and positive catch mechanism to hold at least one position of the sash. As the sash is pivoted, the stay member has one end moved in an arc by the support member while its other end is constrained to reciprocation within the body. The catch mechanism may be operable from a remote position on the frame.
Abstract:
Each of paired pivot mechanisms pivotally holding a window sash within a supporting frame comprises a stationary base screwed to one of the constituent members of the supporting frame and a pivot-carrying movable base fitted over the stationary base. By manipulation of a pair of adjusting screws the movable base can be adjustably moved relatively to the stationary base in the longitudinal direction of the supporting frame member and, if desired, away from or back toward the same. The movable base is screwed to the supporting frame member via the stationary base in a desired position. The mechanism is equally applicable to either vertically or horizontally pivoted windows.
Abstract:
The hinge (10) is intended for a roof window having a frame and a sash, and has a frame hinge part (100) and a sash hinge part (200) configured to assume an angle relative to the frame hinge part (100). Each hinge part (100, 200) has a base plate (110, 210) with a guide track (112, 212) and a link (120, 220), the links (120, 220) being connected to each other at a bearing axle (123). Each link (120, 220) has a first hinged joint (121, 221) to the respective base plate (110, 210) and a sliding joint (122, 222) slidably received in the guide track (212, 112) in the base plate (210, 110) of the other hinge part (200, 100). A pick-up element (130, 230) is connected to the base plate (110, 210) in a second hinged joint (131, 231) and is biased by a spring (140, 240) to act on the sliding joint (222, 122) in the guide track (112, 212), for instance within a predefined angle interval.
Abstract:
The present invention relates to a door hinge system which can be mounted readily on a door body in a short time and which comprises a hinge member to be fixedly secured to a stile member of the door body, and a support member for supporting the hinge member from under or from above. The hinge member has a mounting surface portion which is formed on one side surface thereof and which has mounting screw-threaded holes perforated therein. This mounting surface portion is fixedly secured by means of fasteners through a seating plate to one side wall of the stile member of the door body. The portion of the side wall to be fitted with the hinge system is positioned relative to the mounting surface portion by insert portion(s) and engaging portions located at predetermined positions on the mounting surface portion.
