Description

Sunshade

Technical field

The present invention relates to sunshade or ante-venna, it can be installed to any proper supporting part (for example, the exterior wall of building or separate frame or pillar) and it can stretch out to provide cool place or withdrawal in order to deposit.

Background technology

In whole manual, do not represent for any discussion of prior art and admit that the prior art is known or forms the part of common sense in this area.

Building or other structures can be provided with the permanent or semipermanent sunshade of rigidity; It is the little local roof of top, crested zone effectively, though they are firm, has significant disadvantages, and namely when not needing to cover, they can not be removed.

For removable sunshade, it must be designed to can to remove fully when not required (this generally is inconvenient and labour-intensive) or whole or part sunshade must be designed to withdrawing when not required or folding up.

The regracting sunshade of conventional design comprises along an end and (for example is fixed to braced structures, the wall of building) support frame is so that it is protruding from building, and it is supporting the covering of flexible material, covering can stretch out to cover desired zone in part or the whole length of framework, perhaps withdraws backward towards the end that is fixed to braced structures of covering when not in use.

One of the simplest design of the type is improved roller blind in essence :-the flexible material that forms covering is wound on the spring-loaded roller, roller is installed near the described edge of framework, when needs cover, with flexible material from the roller around down, spring load by roller keeps tension, and is fixed on the frame edge opposite with a described edge.This design is simple and is cheap for manufacturing, and the advantage that has is when flexible material is wound on the roller, flexible material only is exposed to weather in minimum level ground, but its major defect is that flexible material is not supported well when flexible material reaches hidden position, and suffers windburn easily and damage.The deficiency of flexible material support member means that also this design only is suitable for little sunshade.

Above-mentioned shortcoming can be overcome; For example, described in patent NZ336577, it has disclosed a kind of sunshade design, and wherein by the rib support flexible material, rib extends across frame width ground with the spacing that separates along the length of flexible material.The engaged at end of these ribs is along the track at frame side edge, so that sunshade is supported well in extended position and is not easy to suffer windburn very much and damages.The support that gives flexible material by rib means that also this design can be used for big sunshade.Yet the shortcoming of this design is that flexible material is suspended between the rib as ring when sunshade is withdrawn, and is adjacent with the bearing edge of framework, and the ring of flexible material has the trend of the dust of collecting rainwater and being blown up, and flexible material itself is exposed in the weather.
