Abstract

A hinge for pivot roof windows, according to the present invention, comprises two hinge parts, one hinge part (A) secured to a window frame, and the other hinge part (B) secured to the side member of a sash frame. Each hinge part has a base plate (1A, 1B) fitted with securing means (2) and with means (4, 6) for performing pivoting of the base plates (1A, 1B) relative to each other, at the same time a hinge is equipped with at least one fastening unit comprising an arm (9), being an extension of the base plate and a slidable fastener (11) with a hole (13) perpendicular to the fastener slide direction secured to the arm (9) and a securing member (14) secured in parallel to the fastener slide direction. If a hinge has only one fastening unit (9, 10), which constitutes a part of one base plate (1A, 1B), the other base plate is equipped with the known fixed fastener.

Description

The present invention concerns a hinge for a roof window with a pivot sash, equipped with a slidable fastener for screw fastening an external covering member to a side window member.
On the external side the roof windows are equipped with covering members, usually made of metal, which protect a window frame and a sash against unfavourable influence of atmospheric conditions. In the case of windows with a pivot sash which have the rotation axis between the top and the bottom window frame member two covering members are used, which are secured to the window side members, one of them is above and the other one below the rotation axis of the sash.
Side covering members are most often screw fastened and have holes for securing screws at both ends, at the same time the hole spacing is constant. In the side members of a roof window the holes for securing screws which are located near the top member of a window frame and the bottom member of a sash are usually made in securing sockets provided at both ends of the side members of a window whereas near the rotating axis of the sash, the holes for securing screws are located in fasteners constituting a part of the pivot hinge.
A hinge for a roof pivot window is known ( WO/0131155 ), which comprises a hinge part secured to a window frame and a hinge part secured to a sash of a window. Each hinge part has a base plate for securement by fastening screws through screw holes. One side of the base plate has additional means for securing the plate to a window frame or a sash and the other side of the base plate has members enabling pivoting of the base plates relative to each other. Additionally each base plate has at one end a fastener with a screw hole for securing side covering members near the rotation axis of a sash. The fastener constitutes a monolithic element of the base plate of a fixed position.
A hinge for a roof window with a pivot sash ( WO/2006002633 ), equipped with two fasteners with screw holes is known. One fastener is snap fastened in a holder constituting a monolithic member of the base plate secured to a sash and the other one constitutes a monolithic part of the hinge intermediate member, which is riveted to the base plate secured to the side member of a window frame. The position of the both fasteners with screw holes is fixed relative to the base plates of the pivot hinge.
A hinge used in roof windows with a pivot sash (VELUX), the base plates of which have a single holder each at the opposite ends for snapping of fasteners with a screw hole is known. Each holder is a monolithic member of the base plate. Position of the holders and thus of the fasteners seated in the holders is fixed relative to the base plates of the pivot hinge.
Even though the technological regime is followed, often the hole spacing in the side member of a window is not the same as the screw hole spacing in the cover member. If the corresponding pairs of holes in window members and cover members connected together are not coaxial as required, a fastening screw is screwed in at an angle other than 90°. This hinders assembly work and affects the aesthetic qualities of connection of the cover members to the side members of a window.
As follows from experience, securing cover members to side members of a window with fastening screws put into fixed holes causes assembly problems.
An object of the present invention is to eliminate this inconvenience by equipping a pivot roof window with hinges having fasteners slidable lengthwise to the side member of a window, which always enable coaxial setting of the hole in the fastener relative to the hole in the cover member during securing these members with a screw.
A hinge for pivot roof windows, according to the present invention comprises two hinge parts, one hinge part secured to a window frame, and the other one secured to the side member of a sash. Each hinge part has a base plate fitted on one side with securing means and on the other side with means performing pivoting of the base plates relative to each other, at the same time a hinge is equipped with at least one fastening unit comprising an arm, being an extension of a base plate and a slide fastener with a hole perpendicular to the fastener slide direction secured to this arm. If a hinge has only one fastening unit which constitutes a part of one base plate, the other base plate is equipped with the known fixed fastener.
A hinge for roof windows according to the present invention is presented in examples of the embodiment on the drawing where fig. 1 and 2 show two side views of a hinge part mounted to a window frame, fig. 3 and 4 show two side views of a hinge part mounted to a sash of a window, in the first embodiment example; in the second embodiment example fig. 5 and 6 show two side views of a hinge part mounted to a window frame, fig. 7 and 8 show two side views of a hinge part mounted to a sash of a window; in the third embodiment example fig. 9 and 10 show two side views of a hinge part mounted to a window frame, fig. 11 and 12 show two side views of the hinge part mounted to a sash of a window whereas fig. 13 and 14 show two side views of a hinge part mounted to a window frame and fig. 15 and 16 show two side views of a hinge part mounted to a sash of a window in the fourth embodiment example.

Both hinge parts have base plates 1A and 1B with screw holes 2 for fastening screws with additional fastening members 3 on one surface. On the other surface, the base plate 1A has a multi-member arched guide 4 with a guide member 5 and the base plate 1B has a pivoting hook 6, the arch bent arm of which mates the guide 4, and a guide pin 7 and a bumper 8, which limits the range of the hook 6 pivoting.
At one end the base plates 1A and 1 B have cubicoidal arms 9, constituting their extension, at the same time the plate 1A with the arm 9 and the plate 1 B with the arm 9 have Z-shaped longitudinal section. The arms 9 are located relative to the base plates so that after securing the plate 1A to the side member of a window frame, the arm 9 is above the rotation axis of the sash, whereas after securing the plate 1 B to the side member of a sash, the arm 9 is below the rotation axis of the sash. A slidable fastener, comprising an elongated cylinder 10 and an elongated cubicoidal plate 11, interpenetrating with their elongated surfaces at one side of the plate 11, is slid over the arm 9. The fastener is topped with a flat plate 12 at one end. In the cylindrical part 10 of the fastener a circular coaxial hole 13 is made, perpendicular to the fastener slide direction and in the cubicoidal plate 11 in parallel to the fastener slide direction a channel 14 is made, which constitutes a securing member of the fastener. The channel 14 does not cross the hole 13 and has a shape of a rectangle, whose dimensions map the dimensions of the cross-section of the arms 9 the fastener will be slid over. The base plates 1A and 1 B are made of metal and the fasteners of plastics material.
