DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a pivotable balcony glazing structure or a similar wall-like covering formed by sheet-like sections, wherein each sheet is suspended by its top or bottom edge, preferably at two points, to a bearing rail secured to a balcony structure or a like and the opposite edge of a sheet is supported by one point on a second bearing rail secured to a balcony structure or a like, whereby the sheets can be carried one by one upon their points of support to the edge of an opening covered by the sheets and pivoted there upon the sheet hinge pins fitted in the points of support aligned with each other at the top and bottom edge of a sheet for example through 90.degree. so as to expose the outward-facing surface of a sheet.
The glazings for apartment house balconies have become more and more popular over the recent years. The traditional glazing type is such that the open side of a balcony is covered with sashed glass panes sliding upon rails mounted on the top and bottom edge, said panes overlapping in lateral direction. A drawback in this solution is that the glazing cannot be fully opened, which would be desirable e.g. on a hot day. Secondly, washing of their outward-facing surfaces is difficult and dangerous. In addition, the sash-fitted panes impair the appearance of a facade. Due to the above drawbacks, such glazings have not been accepted in quite a few cities.
Another prior known glazing type is the one wherein the panes can be pivoted adjacent to the side wall of a balcony about a vertical axis to lie inside a balcony. This is accomplished by means of a double-rail, the inner one turning at the edge of a balcony to form a special pivoting rail which is mounted on the ceiling of a balcony. The panes are sliding upon two trolleys which are mounted on the top edge and journalled upon vertical axles in the top pane corners. When the trolley running on the inner rail reaches the pivoting rail, the corresponding edge of a pane swings inside a balcony. Thus, the pivoting occurs on three points, i.e. upon trolleys on the top edge and a single slider on the bottom edge.
The main drawbacks in this type of glazing are as follows:
due to the constructional reasons, a 1-wheel trolley pivotable on a vertical axle produces friction between the wheel and the rail which may lead to excessive wear.
Mounting of the pivoting rail requires exact precision since even a slight deviation of height can cause friction between the wheels and the rail, thus hampering the pivoting movement of the panes.
A pivoting rail fitted to the ceiling of a balcony is aesthetically undesirable.
The pivoting-railed structure restricts the width of a pane to circa 650 mm since the handling of wider panes becomes inconvenient.
In an effort to eliminate these drawbacks a structure of the invention is designed in a manner that one of the hinge pins of a sheet, preferably the top edge hinge pin, is fitted with a latch which immobilizes the hinge pin when the sheet is pivoted on the hinge pins.
In one preferred embodiment of the invention, the latch preferably comprises a bracket-like member which is made of a flexible material, preferably spring steel, and which is adapted to engage with a toothed portion mounted on the bearing rail or formed integrally therewith.
Another preferred embodiment of the invention is designed in a manner that the latch is adapted to rotate relative to the hinge pin through the intermediary of a spring to a latch locking position when a sheet is pivoted on the hinge pins.
A solution of the invention offers the following benefits over the prior art:
In a sliding position the carrier wheel is propped to extend parallel to the rail to thus eliminate the friction between wheel and rail.
The 90.degree. rotation of a pane is effected upon two points, i.e. upon axle stubs fitted to the top and bottom corner of a pane the same way as hinges, so a possible inexact fitting does not affect the pivoting movement.
A structure of the invention does not require aesthetically undesired parts jutting out of the side
