Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
291 words
A collapsible wind and/or sunshade screen comprising: a cover, a stand supporting said cover including two outer ribs mounted for movement to an opened up position in which said outer ribs are located in a common plane which is at least substantially perpendicular to said cover, at least one intermediary rib positioned between said outer ribs, said ribs being secured to said cover for positioning the same in a collapsed condition and in stretched condition forming a screen, said ribs having axles at their one end, a hub receiving said axles for holding said ribs together at said one end thereof to extend radially from said hub, said axles being approximately perpendicular to the portion of said cover near said hub, said ribs being pivotally movable about said axles received in said hub for movement relative to one another for moving said cover from the collapsed condition to the stretched condition, means interconnected between said outer ribs and said intermediary rib for moving said ribs to a separated position to maintain said cover in said stretched condition, and an elongated screen support for holding the screen in an upright position on a foundation and to counteract the upsetting thereof, said screen support being arranged to penetrate into said hub and to extend on an axis approximately perpendicular to the portion of said cover near said hub, said screen support penetrating said hub at approximately the same level as the axles of said outer ribs, said screen support having portions extending a substantial distance on both sides of said cover, said screen support comprising two portions pivotally connected with the hub, the pivoting axles of said portions being at least approximately parallel inter se and perpendicular to said axles of the ribs.
Claim 2
Dependent Claim
291 words
A collapsible wind and/or sunshade screen comprising: a cover, a stand supporting said cover including two outer ribs mounted for movement to an opened up position in which said outer ribs are located in a common plane which is at least substantially perpendicular to said cover, at least one intermediary rib positioned between said outer ribs, said ribs being secured to said cover for positioning the same in a collapsed condition and in stretched condition forming a screen, said ribs having axles at their one end, a hub receiving said axles for holding said ribs together at said one end thereof to extend radially from said hub, said axles being approximately perpendicular to the portion of said cover near said hub, said ribs being pivotally movable about said axles received in said hub for movement relative to one another for moving said cover from the collapsed condition to the stretched condition, means interconnected between said outer ribs and said intermediary rib for moving said ribs to a separated position to maintain said cover in said stretched condition, and an elongated screen support for holding the screen in an upright position on a foundation and to counteract the upsetting thereof, said screen support being arranged to penetrate into said hub and to extend on an axis approximately perpendicular to the portion of said cover near said hub, said screen support penetrating said hub at approximately the same level as the axles of said outer ribs, said screen support having portions extending a substantial distance on both sides of said cover, said screen support comprising two portions pivotally connected with the hub, the pivoting axles of said portions being at least approximately parallel inter se and perpendicular to said axles of the ribs.
Claim 3
Dependent Claim
42 words
A collapsible wind and/or sunshade screen according to claim 1, in which said rib interconnecting means comprises two bracing rods each of which is pivotally and displaceably connected at its ends to the intermediary rib and to one of the outer ribs.
Claim 4
Dependent Claim
60 words
A collapsible wind and/or sunshade screen according to claim 1, in which said rib interconnecting means comprises two bracing rods, each of which is formed by two articulated rods acting like joint levers, one of said bracing rods being articulated to the intermediary rib and the other one of said bracing rods being articulated to one of the outer ribs.
Claim 5
Dependent Claim
48 words
A collapsible wind and/or sunshade screen according to claim 1, in which said ribs are bent at least along part of their length and said cover is formed in such a way that the screen obtains one concave and one convex face when moved to said stretched condition.
Claim 6
Dependent Claim
46 words
A collapsible wind and/or sunshade screen according to claim 1, wherein said two screen support portions are arranged in their opened up position to be essentially on either side of said cover and in this position to be blocked by projections provided at said outer ribs.
Claim 7
Dependent Claim
41 words
A collapsible wind and/or sunshade screen according to claim 1, wherein each rib comprises two members articulated inter se and provided with a releasable catch, the articular axle of said members being at least approximately perpendicular to the rib hub axle.
Claim 8
Dependent Claim
36 words
A collapsible wind and/or sunshade screen according to claim 1, wherein each rib consists of two members insertable longitudinally inter se and including a releasable locking device for holding said members in a pulled out position.
