DESCRIPTION:
BRIEF SUMMARY
This invention relates to a window sash consisting of a glass-supporting frame adapted to be hinged in a casing and provided with an operating handle to hold the sash at least in one position in relation to the casing. The handle may thus solely serve as a closure-means, but it may as well be a setting rod or a socalled casement stay.
Windows, including also window sashes separately, are increasingly manufactured by series or mass production in a relatively small number of sizes and frequently in such a manner that uniform window sashes may be used in connection with different types of casings. The purpose is obviously to entail a reduction of the cost price of the windows and of the required artisan's work at the site of installation. Window sashes may accordingly be completely finished in factory (i.e. glass and required frame fixture mounted), but it is then a demand that the factory also cares to deliver the windows in a perfect state to the purchaser, and this implies a compact and safe packaging of the window sashes either separately, e.g. as spare parts or exchange parts, or in an adequate, generally small number. In this respect the operating handle may be disadvantageous, firstly because it requires extra space with a view to packaging, secondly because it involves a certain risk of crushing the glass when handling the packed article.
It is the purpose of the invention to eliminate said inconveniences, i.e. so as to allow a space-saving and safe shipping of the window sashes to the site of use, and this is according to the invention obtained in that a holder is fixed between the frame and the glass, the handle being mountable on said holder by deformation of a securing spring attached to the holder and which when unloaded prevents the handle from being dismounted from the holder.
The mounting of the holder and of the spring may without noticeably complicating the work be effected in connection with the mounting of the glass, and the parts concerned generally lie within the frame thickness reckoned perpendicularly to the plane of the window sash so that they will not impede the packaging. A handle delivered along with the window sash or a handle already available at the site of use can easily and quickly be mounted or stuck on by overcoming the resiliency of the spring, following which said spring will protect the handle from falling off or being unintentionally released. On the other hand, an adequate manipulation of the spring makes it possible to detach the handle, for instance with respect to be re-used with an exchange window after glass crushing or if it is desired to mount a handle of another type or different look.
Further characteristic features of the window sash according to the invention will appear from the following description of an embodiment with reference to the drawing, in which
FIG. 1 is a horizontal sectional view of the portion of a window sash opposite its hinge edge and with an operating handle and an adjacent casing portion,
FIG. 2 is a plane view of a handle holder,
FIG. 3 is a corresponding edge picture, and
FIG. 4 is a plane view of the one end portion of the operating handle.
The window sash 1 fragmentarily illustrated in FIG. 1 includes a frame 2, e.g. of extruded or laminated aluminium, and an insulating pane 3 with two layers of glass mounted in said frame. The sash is supposed to be provided with hinges in its left side, not shown, allowing it to be swung open outwardly in relation to an associated casing 4.
When mounting the pane 3 a holder 5 is inserted between the pane and the inwards facing flange of the frame 2, see also FIGS. 2 and 3, said holder consisting of a piece of sheet metal bent into Z-shape and locally covering the edge of the pane and extending inwards along its inner surface to a point slightly beyond the inner edge of the frame, and an L-shaped leaf spring 6 is held between the frame and the holder and terminates in a tongue 7 bent outwards relative to the holder and pointing to a ledge 8 provided in an end portion 10 of the holder 5 presenting a
