Braceable, unsupported arch arrangement and protective roof comprising it
First Claim
1. A braceable, unsupported arch arrangement comprising:
- at least one elongated, bendable arch portion providing a restoring force when bent;
at least one longitudinal bracing portion for bending and bracing at least one bendable arch portion;
at least one sheet-like connecting portion for holding said at least one bracing portion and said at least one arch portion curved to the same side, said bracing portion and said arch portion being in adjacent relationship at opposite sides of said connection portion, wherein said arch portion has a greater overall curvature than said bracing portion; and
at least one pair of end connections for interconnecting said arch portion and said bracing portion in braced condition at respective end regions thereof;
wherein said arch arrangement is to be set up by bracing said at least one arch portion by said at least one bracing portion; and
said arch arrangement being tensioned by the restoring force of said at least one arch portion, and being form-stabilized by said connecting portion, thereby being stable in unsupported conditions.

Abstract
An arch element (1") for protecting roofs has at least one tubular arch (2) held in the curved state by at least one brace (4). The ends of arch and brace (2, 4) are interconnected by end connectors (3). In order to keep the brace (2) out of the direct connection between both end connectors (3) and to guide it along the arch (2) at a certain distance thereof, a flat connecting part (5) is arranged between and joined to arch and brace (2, 4). By using three arches (2), two braces (4) designed as bracing booms, four fabric or plastic connecting surfaces (5) that join the braces (4) to the arches (2), and three spacers (10) that keep the outer arches (2) apart, an unsupported, dimensionally stable three-dimensional arch element (1") is obtained that may be used directly as a shade or associated to other arch elements to carry roof surfaces. By using arches (2), spacers (10) and end connectors (3) that can be plugged into each other, the arch element (1") may be dismounted.

31. A protective roof comprising a roof surface and at least one arch arrangement supporting said roof surface, wherein said at least one arch arrangement comprises:
-
at least one elongated, bendable arch portion providing a restoring force when bent; at least one longitudinal bracing portion for bending and bracing said at least one arch portion; at least one sheet-like connecting portion for holding said at least one bracing portion and said at least one arch portion curved to the same side, said bracing portion and said arch portion being in adjacent relationship at opposite sides of said connection portion, wherein said arch portion has a greater overall curvature than said bracing portion; and at least one pair of end connections for interconnecting said arch portion and said bracing portion in braced condition at respective end regions thereof; wherein said arch arrangement is set up by bracing said at least one arch portion by said at least one bracing portion; and
said arch arrangement being tensioned by said restoring force of at least one of said arch portions, and being form-stabilized by said connecting portion, thereby being stable in unsupported conditions. - View Dependent Claims (32, 33, 34, 35)
