DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a pivotable glazing for a balcony.
The protecting of balcony spaces with glass is becoming more common. In the northern climate, effective use of an open-air balcony is limited to a rather short summer season. By installing glass panes on the open side of the balcony it is possible to multiply the usability of the balcony. By means of glass panes which cover the open wall opening, the air temperature on the balcony can be increased, and at the same time the penetration of wind, noise and dust into the balcony can be prevented. On the other hand, sunshine may also cause excessive heat in summertime on a balcony facing south or southwest and may thus hamper the use of the balcony, in which case it is advantageous to prevent sun rays from entering the balcony.
In present-day constructions, the glazing of a balcony is made up of four or more panes which slide in an overlapping manner, on two tracks, at the head and the base. Such a construction has several deficiencies:
The front wall of the balcony can be opened at most 50%, in which case excessive heat will constitute a problem in summertime;
the washing of the outside surface of the panes is difficult. The panes must be lifted out of place, which constitutes a risk, or the panes must be washed from the outside, which is also dangerous;
the sealing of overlapping glass surfaces imposes its own requirements, the panes must be equipped with a sturdy frame, in which case the glazing will substantially change the appearance of the facade of the building.
The construction according to the present invention eliminates the above-mentioned disadvantages, and it is characterized primarily by providing panes and side panes which are rotatable about 180.degree. such that the face of the pane can be changed from having been turned outside, and vice-versa.
The construction according to the invention thus has as its starting point a pivotable glazing, which comprises two or more movable panes, preferably covering the entire width of the balcony; these panes slide on upper and lower tracks secured to the ceiling structures and respectively to the balustrade structures of the balcony. At the upper edge of each pane there is a profile having at least two slides at a distance from each other and rotating about their vertical axes; one of these slides runs on the straight outer rail of the upper track and the other one runs on the inner rail, which turns inwards and to the side. At the lower edge of each pane there is a profile having slides rotating about their vertical axes, these slides moving on the lower track of the balcony.
According to the invention, the inner rail of the upper track is curved in shape so that in the main it has approximately the shape of a circle arc the center point of which is close to the corner of the balcony balustrade and the side wall and the radius of which is at maximum equal to the pane width. By means of this arrangement, a pane to be moved can be guided within the curved portion of the inner rail in such a way that the pane surface facing inwards will lead the movement and will settle against the side wall, and further back to the initial position or to a 180.degree. pivoted position, in which the side which originally faced inwards will face outwards. The slide which is at the lower edge of the pane in the turning part of the pane is fitted so as to separate from the lower track when the pane turns inwards from the upper inner rail.
According to a preferred embodiment, the curved rail portion of the inner rail forms a gently curving inverted S-shape. Thus the pivoting movement will consist of a slow, flexible initial turning, an even middle movement which follows the arc of a circle, and finally a slow, turning and pushing movement.
The curved portion of the inner rail is preferably spaced apart from the side wall in such a manner that, when necessary, the panes can be removed.
In a preferred embodiment of the invention, of the slides at the upper edge the one which moves on the outer rail is located at th
