Abstract

The invention relates to a collapsible umbrella having at least one pair ofanopy rod parts (1,2), which extend alongside one another and are guided so as to be displaceable on one another, within each linkage of the canopy-supporting linkage frame. One of the canopy rod parts (2) is composed of wire, and guided on the other rod part (1) by means of a bight (2e) of the wire which embraces the other rod part and is formed with hooks (2f,2g) which can be spread to allow the bight to be fitted transversely on the other rod.

Claims

1. In a folding umbrella comprising a canopy-supporting framework with a plurality of linkages each including a pair of rod parts which extend alongside one another and are guided for relative longitudinal displacement by an integral bent portion of one of said pair of rod parts, which one rod part is made of wire and engages around the other rod part;

characterized in the bent portion in the one rod part made of wire is a bight which embraces the other rod part and terminates in opposed hooks which secure the bight on the other rod part and which can be spread apart to enable the other rod part to pass transversely between the hooks for assembling and disassembling the pair of rod parts, said bight being constructed of spring wire and comprising opposed portions defining jaws;

said jaws being disposed in a flanking relation to the other rod part from opposite sides, said jaws being resiliently spreadable apart for removably clipping the bight onto the other rod part.

2. A folding umbrella according to claim 1, wherein said bight is bent so that the parts of the wire rod part on each side of the bight lead from a mid part of the bight between the jaws.

3. A folding umbrella according to claim 1, wherein said second rod part has a channel-shaped cross section into which the hooks engage.

4. A folding umbrella according to claim 1, wherein said hooks engage around one another.

5. A folding umbrella according to claim 1, wherein said bight is constructed as a double ring interconnected by a straight bridge.

6. A folding umbrella having a canopy supported by a frame according to claim 1.
