Description

A WINDOW ASSEMBLY

FIELD

[0001] The present invention relates to windows and doors and more particularly but not exclusively to windows and doors that have a pivotally mounted panel.

BACKGROUND

[0002] Window assemblies available include windows in which there is a frame to be fixed to a supporting structure. Pivotally attached to the frame so as to be angularly movable about a generally upright axis or a generally horizontal axis is a panel. Typically the panel would include a glass sheet.

[0003] To secure the panel in a closed position the surrounding frame is provided with a plurality of spaced keepers. The pivoted panel has a plurality of lugs that are driven by a strip between a release position and a lock position. When the panel is in the closed position and the lugs are moved to the lock position, the panel is fixed to the frame and cannot be opened. However operation of the device to move the lugs from engagement with the keepers enables the panel to be opened. Mounted on the panel is a lever that is operated by a user to move the lugs between the release and lock positions.

[0004] A disadvantage of the above discussed construction is that the handle (and its mounting assembly) prohibit or at least hinder installation of a fly screen.

DESCRIPTION OF EMBODIMENTS

[0027] In the accompanying drawings there is schematically depicted an assembly 10. The assembly 10 may be a window assembly 10 or a door assembly 10. However in the following description, the assembly 10 will be considered to be a window assembly.

[0028] The window assembly 10 includes a window frame 11 that is to be fixed to a supporting structure. The frame 11 includes a sill 12, a head 13 and upwardly oriented jambs 14 extending between the sill 12 and head 13 so that the frame 11 is of a generally square or rectangular configuration. The frame 11 surrounds a window opening 15 that is closed by means of a panel 16.

[0029] Preferably, the panel 16 is pivotally mounted on the frame 11 for angular movement about a generally horizontal axis adjacent the head 13. Preferably, the panel 16 is of a square or rectangular configuration and includes a panel frame 17 including a bottom rail 18, a top rail 19 and a pair of upwardly oriented side rails 20. The rails 18, 19 and 20 surround an opening that receives a glass sheet to be supported by the frame 17.

[0030] Mounted on the sill 12 is a window chain winder 21. The winder 21 includes a chain (not illustrated) that extends from the window winder 21 to the bottom rail 18. Upon operation of the winder, the panel 16 is caused to move angularly between an open position and a closed position about the abovementioned horizontal axis. The closed position of the panel 16 is illustrated in Figure 9.

[0031] Fixed to the sill 12, head 13 and side jambs 14 is a plurality of keepers 22. Each of the keepers 22 is fixed to its associated sill 12, head 13 or jamb 14 so as to be adjustable in position. However once in the correct position, each keeper 12 is then fixed by means of threaded fasteners. Each keeper 22 includes a keeper projection 23.

[0032] The keepers 22 are located at spaced locations so that the sill 12, and/or head 13, and/or jambs 14 may have one or more keepers 22.

[0033] Mounted on the frame 17 is a plurality of lugs 24. Preferably for each keeper 22 there is an associated one of the lugs 24. The lugs 24 are movably mounted on the frame 17 and are coupled by means of a drive mechanism 25. The drive mechanism 25 includes a plurality of strips 26 that are coupled and extend around the entire periphery of the frame 17. The lugs 24 are fixed to the drive mechanism 25 so that the lugs 24 are moved in unison along generally linear paths.

[0034] The lugs 24 include a drive lug 33.

[0035] Mounted on the frame 11 is an actuator 27 that includes a body 28 that pivotally supports a lever 29 for angular movement about an axis 30. Preferably, the actuator 27 is mounted on one of the jambs 14. The lever 29 has an end extremity 31 engaged with an actuator part 32. The end extremity 31 has a projection engaged in a slot 35 of the part 32.

The part 32 has a pair of projections that engage a pair of recesses that restrain the part 32 to follow a generally linear path 36. The path 36 is generally perpendicular relative to the axis 30 but displaced therefrom. The path 36 is also generally parallel to the jamb 14. The actuator 27 and part 32 are portions of a locking mechanism that is operable to fix the panel 16 to the frame 11.

[0036] The part 32 has a pair of projections 37 between which there is located a recess 38.

[0037] The recess 38 is adapted to receive the drive lug 33.

[0038] Attached to the frame 17 are resilient locating members 39 that engage the drive mechanism 25 to define the two positions thereof, that is the lock position and the release position of the lugs 24 with respect to the keepers 22.

[0039] The frames 11 and 17 are formed of aluminum extrusions, with the rails 18, 19 and 20, each being provided with a longitudinally extending slot 39 within which the drive mechanism 25 is slidably located for longitudinal sliding movement therealong. The other preferred forms the frames 11 and 17 may be formed of timber or UPVC.

[0040] In operation of the above described window assembly 10, when the panel 16 is moved to the closed position the drive lug 33 enters the recess 38. Thereafter the lever 29 is moved angularly about the axis 30 to cause movement of the part 32 in the direction of the path 36. This in turn takes with it the drive lug 33. Movement of the drive lug 33 in turn causes movement of the drive mechanism 25. The lugs 24 are then moved behind the keeper projections 23 to prevent pivoting movement of the panel 16 away from the frame 11. When the handle 29 is pivoted in the reverse direction, the lugs 26 are moved from behind the projections 23 thereby releasing the panel 16 for pivoting movement.
