Abstract
Abstract Awning with a canopy consisting of several strips (18) extending in the direction of extension which are rolled up on one and the same canopy roller. The longitudinal edges of the strips (418, 518, 618) can overlap one another, and the strips (418, 518) can be attached on the canopy roller (13, 113), offset with respect to one another in the circumferential direction thereof, while being connectible to one another along their longitudinal edges by the use of a fastening device such as a bristle trim or the like (23, 24), or with the edges adjacent each other without overlapping, whereby the edges can be released or separated by the application of wind pressure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
238 words
In an awning construction which blocks light and wind, while permitting passage therethrough of wind pressure above a predetermined level to prevent damage to said awning; canopy means having a first end and a second end; roller means for coiling-up said canopy means; the first end of said canopy means being connected to said roller means; spanning means connected to said second end of said canopy means and movable relative to said roller means; said canopy means including a plurality of strip means forming a canopy and extending parallel to each other and substantially retained in a single plane between said roller means and said spanning means; each of said strip means being substantially impervious to air; said strip means each having lateral edges extending in a longitudinal direction of said strip means, said lateral edges of adjacent ones of said strip means being near enough to one another, while substantially not overlapping each other, to form a substantially continuous appearance for said canopy; said strip means having sufficient flexibility, when subjected to said wind pressure, to be deflected by said wind pressure above a predetermined level to individually form an arch to create a space between adjacent said lateral edges to permit the wind to pass through said canopy means; and further comprising releasable fastening means on said lateral edges of said strip means for interconnecting the latter and for being automatically released under a predetermined tension.
Claim 2
Dependent Claim

Claim 8
Dependent Claim
316 words
In an awning construction which blocks light and wind, while permitting passage therethrough of wind pressure above a predetermined level to prevent damage to said awning; first canopy means having a first end and a second end; second canopy means having a first end and a second end; roller means for coiling-up said first and second canopy means in two parallel layers, said first ends of both said canopy means being connected to said roller means; first spanning means connected to the second end of said first canopy means and movable in a first direction relative to said roller means; second spanning means connected to the second end of said second canopy means and movable in a second direction relative to said roller means; first guide means for guiding said first canopy means in said first direction; and second guide means for guiding said second canopy means in said second direction; each said canopy means including a plurality of strip means forming a canopy and extending parallel to each other and substantially retained in a single plane between said roller means and said spanning means; each of said strip means being substantially impervious to air; said strip means each having lateral edges extending in a longitudinal direction of said strip means, said lateral edges of adjacent ones of said strip means being near enough to one another, while substantially not overlapping each other, to form a substantially continuous appearance for said canopy; said strip means having sufficient flexibility, when subjected to said wind pressure, to be deflected by said wind pressure above a predetermined level to individually form an arch to create a space between adjacent said lateral edges to permit the wind to pass through said canopy means; and further comprising releasable fastening means on said lateral edges of said strip means for interconnecting the latter and for being automatically released under a predetermined tension.
Claim 9
Dependent Claim
316 words
In an awning construction which blocks light and wind, while permitting passage therethrough of wind pressure above a predetermined level to prevent damage to said awning; first canopy means having a first end and a second end; second canopy means having a first end and a second end; roller means for coiling-up said first and second canopy means in two parallel layers, said first ends of both said canopy means being connected to said roller means; first spanning means connected to the second end of said first canopy means and movable in a first direction relative to said roller means; second spanning means connected to the second end of said second canopy means and movable in a second direction relative to said roller means; first guide means for guiding said first canopy means in said first direction; and second guide means for guiding said second canopy means in said second direction; each said canopy means including a plurality of strip means forming a canopy and extending parallel to each other and substantially retained in a single plane between said roller means and said spanning means; each of said strip means being substantially impervious to air; said strip means each having lateral edges extending in a longitudinal direction of said strip means, said lateral edges of adjacent ones of said strip means being near enough to one another, while substantially not overlapping each other, to form a substantially continuous appearance for said canopy; said strip means having sufficient flexibility, when subjected to said wind pressure, to be deflected by said wind pressure above a predetermined level to individually form an arch to create a space between adjacent said lateral edges to permit the wind to pass through said canopy means; and further comprising releasable fastening means on said lateral edges of said strip means for interconnecting the latter and for being automatically released under a predetermined tension.
Claim 10
Dependent Claim
