Abstract
Abstract A vertical louver system comprising a vertical louver support system and a plurality of vertical louvers mounted on the vertical louver support system. Each of the louvers includes a channel having first and second in-turned flanges and a web joining the flanges. An insert is received within the flanges and has reusable adhesive on its outer face to permit a decorative sheet to be attached to the insert. The insert and channel are resiliently bendable but are constructed to provide a strong composite structure which resists warping due to thermal conditions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
A vertical louver system comprising: a plurality of vertical louvers; means for mounting said vertical louvers on said vertical louver supporting system; at least one of said vertical louvers including a channel and a panel-like insert; said channel including first and second flanges and a web joining said flanges, said first flange and said web defining a first elongated receiving zone and said second flange and said web defining a second elongated receiving zone; said insert being curved in transverse cross section when the insert is in an unrestrained condition; said insert being resilient and having sufficient rigidity such that it has a tendency to bend into a relatively sharp curve about a transverse axis with snap action in response to bending loads about such axis and said channel tending to bend about a tranverse axis into a more gradual curve in response to bending loads about such axis whereby said insert and said channel have different bending characteristics when bent separately about a transverse axis; said insert being received in said first and second receiving zones; and means for attaching said insert to said channel.
Claim 2
Dependent Claim
186 words
A vertical louver system comprising: a plurality of vertical louvers; means for mounting said vertical louvers on said vertical louver supporting system; at least one of said vertical louvers including a channel and a panel-like insert; said channel including first and second flanges and a web joining said flanges, said first flange and said web defining a first elongated receiving zone and said second flange and said web defining a second elongated receiving zone; said insert being curved in transverse cross section when the insert is in an unrestrained condition; said insert being resilient and having sufficient rigidity such that it has a tendency to bend into a relatively sharp curve about a transverse axis with snap action in response to bending loads about such axis and said channel tending to bend about a tranverse axis into a more gradual curve in response to bending loads about such axis whereby said insert and said channel have different bending characteristics when bent separately about a transverse axis; said insert being received in said first and second receiving zones; and means for attaching said insert to said channel.
Claim 3
Dependent Claim
37 words
A vertical louver system as defined in claim 1 wherein said insert has an outer face and reusable adhesive on said outer face whereby a decorative sheet can be attached to and removed from said outer face.
Claim 4
Dependent Claim
33 words
A vertical louver system as defined in claim 1 wherein said attaching means includes said insert and said receiving zones cooperating to frictionally at least assist in attaching the insert to the channel.
Claim 5
Dependent Claim
54 words
A vertical louver system as defined in claim 1 wherein said attaching means includes an aperture in said insert, an opening in said channel and a mounting member, said mounting member extends through said aperture and said opening, said mounting member also at least assisting in mounting said one louver on a support system.
Claim 6
Dependent Claim
32 words
A vertical louver system as defined in claim 1 wherein said attaching means includes means adjacent the lower ends of the insert and the channel for attaching the insert to the channel.
Claim 7
Dependent Claim
28 words
A vertical louver system as defined in claim 1 wherein said channel is constructed of a plastic material, said insert is constructed of tempered aluminum or rolled steel.
Claim 8
Dependent Claim
93 words
A vertical louver system as defined in claim 6 wherein said insert has an outer face and reusable adhesive on said outer face whereby a decorative sheet can be attached to and removed from said outer face, said attaching means including said insert having a transverse dimension in its unrestrained condition which exceeds the transverse distance provided by the receiving zones of the channel, said insert being resiliently deflected about said longitudinal axis when it is received by said receiving zones whereby to at least assist in attaching the insert to the channel.
Claim 9
Dependent Claim
24 words
A vertical louver system as defined in claim 1 wherein said insert is spaced from said channel in a region intermediate said receiving zones.
Claim 10
Dependent Claim
46 words
A vertical louver system as defined in claim 1 wherein said channel is curved in transverse section with the curvatures of the insert and channel being convex in the same direction such as to space the channel and the insert in a region intermediate said zones.
