Abstract:
An openable roof window includes: a window panel configured to be slidable along a guide rail to selectively open and close an opening in a roof and tiltable relative to a base frame; a slider having a pin and driven by a drive device to slide along the guide rail; an engagement structure that selectively engages the slider with the window panel such that they are unmovable relative to each other in a direction along the guide rail; and a stay fixedly secured to the window panel and having a cam groove formed therein, the cam groove engaging the pin of the slider and having a shape defined such that, when the engagement structure does not engage the slider with the window panel, the window panel is caused to tilt as the slider moves relative to the stay as a result of sliding of the slider along the guide rail.
Abstract:
An electronically-activated roof access hatch is described that allows an operator to unlock the roof access hatch safely from the ground before ascending to the roof access hatch. The opening of the roof access hatch is controlled by a control panel that unlocks the roof access hatch and causes the roof access hatch to open.
Abstract:
A metal fitting for an all-glass plate member for use as a door, window or the like and including a pair of clamping plates positioned on the opposite face surfaces of the plate member and covering a recess through the plate member. Each clamping plate has an elongated recess aligned with the recess in the plate member. The recess in the plate member and the recesses in the clamping plates define a receiving space for a hinge member. The hinge member is formed of at least two hinge member parts each associated with a different clamping plate with the hinge member plates located within the receseses in the clamping plates. The clamping plate recesses have a pair of shoulders each located at an opposite end of the recess. The hinge member parts bear against the shoulders. The hinge member includes an intermediate part located within the recess in the plate member. On one side the intermediate part has a projecting region in contact with one of the hinge member parts. Bolts interconnect the hinge member parts including the intermediate part.
Abstract:
A skylight and roof assembly with at least a portion of the skylight adapted to be pivoted by a drive mechanism between open and closed positions with respect to an opening in the roof. At least one hinge is connected to the movable portion of the skylight and the fixed portion of the assembly to permit the pivotal movement. The hinge includes a first leg adapted to be mounted on the movble portion of the skylight in fixed position. The hinge includes a second leg adapted to be mounted on the non-movable portion of the skylight and roof assembly. A flange extends from the second leg and mating surfaces are on the first leg and the flange adapted to receive a coupling pin for pivotally interengaging the first and second leg with the first leg spaced from the second leg by the flange therebetween so that the movable portion of the skylight can be pivoted in a desired manner between the open and closed position. An actuator pole is provided for removably engaging and activating the drive mechanism to pivot the skylight portion. The pole is formed of two separable sections, an upper section and a lower section. A spline interconnects the two sections. A handle is removably connected to the lower section and a connector is removably connected to the upper section and is designed for removable engagement with the drive mechanism so that when the handle is shifted the connector activates the drive mechanism and pivots the skylight.
Abstract:
A chain operator for a window, and particularly a skylight window, having a casing with a chain storage area from which a chain can be advanced for opening of the window. The casing is constructed for mounting of different types of drive mechanism for a chain drive sprocket within the casing. A unitary liner is fitted within the casing to provide a reduced friction mounting for the drive sprocket and a reduced friction guide for the chain, with the liner being positioned in high load and high wear areas to result in smooth and quiet long-life operation. The chain operator has a chain composed of solid links pivotally interconnected by U-shaped links and interrelated in a manner to readily move between straight and curved configurations and operate under relatively heavy load.
Abstract:
The novel arrangement relates to a skylight with a case and a wing mounted thereon for pivoting about a horizontal axis and swinging about a further horizontal axis, the swinging axis being partially constituted by axial pins at the sides of the wing which are displaceable while supported on the case, with a cover partially overlapping the wing and case, the cover being pivotally linked at one end to the case and at the other end at the wing, the axial pins being arranged between the linkages and the wing having a guard for covering the case at least in the range not overlapped by the cover, with at least one weight balancing device arranged on one of the longitudinal struts of the wing whose two-armed support lever pivotal about a bearing pin consists of a support arm carrying a roller and a tension arm to which a tension spring is linked which is adjustable by means of a tensioning device affixed to the wing.
Abstract:
A drive system for a movable closure member movable along rail sets carried on opposed sides of the frame of a structure includes a rail set on each side of at least one pair of opposed sides of the frame. Each rail set includes first and second laterally offset toothed sections. Each first section includes a horizontal segment and an inclined segment whereas each second segment includes a vertical segment and an inclined segment which has at least a portion thereof in juxtaposed side-by-side relation with the inclined segment of the first section. An electric motor has a drive shaft that extends transversely of the rail sets and carries a first gear wheel coaxially therewith at each end. Each first gear wheel carries a second and smaller gear wheel eccentrically thereon. The first and second gear wheels have a common point of tangency. The first gear wheels are cooperable with the first sections of the respective rail sets and the second gear wheels are cooperable with the second sections of the respective rail sets. The respective rail sections and gear wheels are dimensioned to provide for transfer of driving force between the first and second gear wheels when the common point of tangency therebetween falls within the juxtaposed side-by-side portions of the respective inclined segments of the rail sets.
