BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention concerns an improved window, the casement of which is pivot-hung in its associated frame.
Double glazing as well as triple glazing windows have been developed lately, in which the window panes are treated to prevent strong heat radiation from entering through the glazing. Instead, part of the heat radiation, it reflected back into the atmosphere. In this manner is has become possible to prevent powerful sunlight to heat the premises in a building excessively during the summer, with resulting economy of for instance the energy required to operate an air conditioning system. In many cases it has also become possible to do without Venitian blinds.
However, as summer progresses into autumn and winter, the conditions are the opposite ones. During this period it is desired to prevent heat from the heated premises from radiating through the windows and into the atmosphere.
SUMMARY OF THE INVENTION
The subject invention provides improvements whereby it becomes possible to make use of the advantages brought about by the kind of windows described above all the year around. This possibility is obtained by making the casement pivotable, from a closed position in the window frame, over half a turn to a closed, fully reversed position and, from the latter position, further pivotable in the same direction or pivotable reversely in the opposite direction. In this manner the improvements allow the user a choice of which side of the window he or she wishes to be directed outwards and which to be turned inwards during a certain period.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention should be described in closer detail in the following with reference to the accompanying drawings, wherein:
FIG. 1 is a cross-sectional view through a part of the casement and of the frame,
FIG. 2 is a schematical view of the frame and its associated casement, the latter assuming various pivotable positions,
FIG. 3 illustrates on an enlarged scale a cross-sectional view through the frame, including a casement locking means, and
FIG. 4 is a perspective view of said locking means.
FIG. 5 is an overall view of the casement and frame, showing the cutting planes on which the respective sectional views are taken.
DETAILED DESCRIPTION
The window to be described in the following consists of a casement 1 which is mounted on pivots in a window frame 2. Each side jamb of the casement 1 intermediate two corner portions consists of two structural profile sections 3, 4, and of a third profile section 5 serving as a glazing strip. The three profile sections 3, 4, 5 extend in mutual parallel relationship. The structural profile sections 3, 4 are interconnected by bridge members 6, 7 having poor heat-conductivity and thus serving to prevent thermal bridges from generating between the external face of the casement 1 to the left in FIG. 1 and its external face to the right in the same drawing figure. A guide bushing 8 is located between the structural profile sections 3 and 4.
The third profile section 5 serving as a glazing strip is formed with a longitudinal edge web 9 which extends past the structural profile section 4 and which together with a corresponding longitudinal edge web 10 on the structural profile section 3 defines a space for reception of an edge portion of the glazing unit 11 which, in accordance with the embodiment illustrated in FIG. 1, consists of three window panes. Screws 12, only one of which is shown in FIG. 1, are equally spaced along said side jamb of the casement 1 in order to secure the profile section 5 to the structure profile sections 3 and 4.
On the screw-insertion face of the casement side jamb, the latter is provided with a covering strip 13 enclosing the longitudinal edge web 9 of profile section 5 in the area adjacent the glazing unit 11. The strip is formed in the area of the opposite longitudinal edge of the profile section 5 with a transverse edge portion 14 which grippingly engages a correspondingly configured transverse edge portion 15 on the profile section 5.
