DESCRIPTION:
BRIEF SUMMARY
The invention relates to a terrace glass enclosure, which is formed essentially by a roof, which extends between a wall of the house and a terrace floor adjoining this wall. Such terrace enclosures, prefabricated from individual elements, easily installable and adaptable with respect to height and depth to the particular circumstances, have not previously been known.
In accordance with the inventive proposal, a terrace glass enclosure, which satisfies these concepts, has the characteristics (a) to (c) of claim 1.
According to these, the terrace glass enclosure comprises essentially a roof between arch elements forming wall and floor; depending on the length of the terrace glass enclosure, a convenient number of such arch elements can be positioned together, and connected with one another to form a seal at their lateral frame parts. The lateral frame parts advisably are one-piece, arch-shaped supports, for example, in the nature of so-called laminates.
The lateral frame parts are connected at their ends by appropriate cross frames into a closed frame. Profiled parts, which form the guides for the glass panes, are provided in or on this frame, each arch element having two glass panes, which mutually overlap, namely an outer glass pane, which is movably held in an outer guide, and an inner glass pane, which is somewhat shorter than the outer glass pane and which is held in an inner guide. To be able to use plane glass panes, these panes must not exceed a certain thickness, about 4 mm, as otherwise they cannot be shaped to correspond to the curvature of the arch elements.
Like the roof, the gable parts, that is, the walls of the terrace glass enclosure that close off the roof at the front, are assembled from prefabricated, individual gable elements. These comprise a square, basic element, which is set up on the terrace floor adjoining the existing wall of the building and the free corner of which supports the arch element assigned to it. The openings, which remain free between the square, basic element and the associated arch element, are closed off by two connecting elements in accordance with characteristic c) of claim 1.
Accordingly, the two connecting elements each have a frame arch; both frame arches together form an arch, which corresponds to the arch elements; the frame arches can form similar or dissimilar arch sections. In the event that the arch sections are similar, the two connecting elements are identical. In the event that the arch elements are dissimilar, the dimensions of the terrace glass enclosure differ in height and depth. Obviously, in the last mentioned case, the two dissimilar elements can be exchanged arbitrarily, so that a lesser depth corresponds to a greater height of the terrace glass enclosure or, conversely, that a greater depth corresponds to a lesser height of the terrace glass enclosure. Using three different connecting elements, it is thus possible to build terrace glass enclosure in three different heights or depths.
In order to brace this construction against lateral shear forces, that is, shear forces acting in the longitudinal direction of the terrace glass enclosure, provisions are made in a refinement of the invention so that transverse and/or diagonal struts are provided between the lateral frame parts of the arch elements in the region of their upper end sections.
These struts can function at the same time as support buffers or rollers, which are disposed closely below the outer pane for support, when this outer pane sags under the load of snow. Such support is advisable since, for reasons already given above, relatively thin glass panes must be used, which cannot withstand heavy loads of snow.
To simplify the manufacture especially of the arch elements, provisions are furthermore made so that the lateral frame parts are constructed linearly in each case in the region of their upper and lower end sections. Accordingly, from geometric considerations, it is advisable to have the lateral frame parts describe an arc of a circle in each case in the region between their uppe
