Abstract
Abstract A swingable bracket assembly for removably holding in operative position the louver or panel of a jalousie window, door or the like having a swingably mounted main bracket member and a louverengaging spring which is quick-detachably interfitted with the bracket member to permit rectilinear insertion of the louver and removal thereof from and into the bracket assembly. The louverengaging spring, which serves to positionably lock the louver in its bracket, is normally provided at its upper end with a lip for engaging the upper edge of a standard size of louver to prevent any upward displacement thereof from the supporting bracket. The locking spring is so designed that its said upper end portion may be cut-off to adapt the bracket for support of a louver which is of a narrower width than the standard size louver normally accomodated in the bracket.

Total Claims: 17
Claim 1
Independent Claim
270 words
A bracket assembly for quick-detachably engaging and supporting one end of a louver in a jalousie frame comprising a. a swingably mounted main bracket member having 1. a mounting flange disposed in a plane extending orthogonally with respect to the plane of the louver for limiting endwise movement thereof, 2. an elongated base flange integral with and right angularly related to said mounting flange adapted to overlie and engage the outside surface of the louver when the same is in substantial engagement with said mounting flange, 3. a louver abutting stop at the bottom end of said base flange, and 4. a pair of vertically spaced parallel lugs extending from said mounting flange crosswise of and at right angles to said base flange with corresponding edges thereof spaced from said base flange a distance greater than the thickness of the jalousie louver, said lugs being respectively provided with vertically registering openings each in the form of an openended slot for permitting edgewise insertion thereinto of a flat leaf spring member, and b. an elongated spring metal member extending through said openings in said lugs in overlying relation to said base flange of said main bracket member, said spring member having spaced portions thereof resiliently biased to engage the inside surface of the jalousie louver when its aforesaid end is disposed in position between said base flange and said spring member, said spring member including means which coact with at least one of said slotted lugs to preclude shifting movement of said spring member longitudinally with respect to said bracket member when said spring member is interfitted in said lug openings.
Claim 2
Dependent Claim
270 words
A bracket assembly for quick-detachably engaging and supporting one end of a louver in a jalousie frame comprising a. a swingably mounted main bracket member having 1. a mounting flange disposed in a plane extending orthogonally with respect to the plane of the louver for limiting endwise movement thereof, 2. an elongated base flange integral with and right angularly related to said mounting flange adapted to overlie and engage the outside surface of the louver when the same is in substantial engagement with said mounting flange, 3. a louver abutting stop at the bottom end of said base flange, and 4. a pair of vertically spaced parallel lugs extending from said mounting flange crosswise of and at right angles to said base flange with corresponding edges thereof spaced from said base flange a distance greater than the thickness of the jalousie louver, said lugs being respectively provided with vertically registering openings each in the form of an openended slot for permitting edgewise insertion thereinto of a flat leaf spring member, and b. an elongated spring metal member extending through said openings in said lugs in overlying relation to said base flange of said main bracket member, said spring member having spaced portions thereof resiliently biased to engage the inside surface of the jalousie louver when its aforesaid end is disposed in position between said base flange and said spring member, said spring member including means which coact with at least one of said slotted lugs to preclude shifting movement of said spring member longitudinally with respect to said bracket member when said spring member is interfitted in said lug openings.
Claim 3
Dependent Claim
36 words
an elongated base flange integral with and right angularly related to said mounting flange adapted to overlie and engage the outside surface of the louver when the same is in substantial engagement with said mounting flange,
Claim 4
Dependent Claim
36 words
an elongated base flange integral with and right angularly related to said mounting flange adapted to overlie and engage the outside surface of the louver when the same is in substantial engagement with said mounting flange,
Claim 5
Dependent Claim
43 words
A bracket assembly as defined in claim 1 wherein the elements set forth in paragraphs a-1 to a-4 thereof constitute integral parts of said bracket member and wherein the element set forth in paragraph (b) thereof is separably interfitted with said bracket member
Claim 6
Dependent Claim
55 words
A bracket assembly as defined in claim 1 wherein said vertically spaced lugs are respectively disposed in substantially parallel planes perpendicular to the plane of said elongated base flange to thereby provide a two-point interlock between said mounting flange and said spring member when the latter is nested in said open-ended slots of said lugs.
Claim 7
Dependent Claim
13 words
a louver abutting stop at the bottom end of said base flange, and
Claim 8
Dependent Claim
13 words
a louver abutting stop at the bottom end of said base flange, and
Claim 9
Dependent Claim
169 words
a pair of vertically spaced parallel lugs extending from said mounting flange crosswise of and at right angles to said base flange with corresponding edges thereof spaced from said base flange a distance greater than the thickness of the jalousie louver, said lugs being respectively provided with vertically registering openings each in the form of an open-ended slot for permitting edgewise insertion thereinto of a flat leaf spring member, and b. an elongated spring metal member extending through said openings in said lugs in overlying relation to said base flange of said main bracket member, said spring member having spaced portions thereof resiliently biased to engage the inside surface of the jalousie louver when its aforesaid end is disposed in position between said base flange and said spring member, said spring member including means which coact with at least one of said slotted lugs to preclude shifting movement of said spring member longitudinally with respect to said bracket member when said spring member is interfitted in said lug openings.
Claim 10
Dependent Claim

a pair of vertically spaced parallel lugs extending from said mounting flange crosswise of and at right angles to said base flange with corresponding edges thereof spaced from said base flange a distance greater than the thickness of the jalousie louver, said lugs being respectively provided with vertically registering openings each in the form of an open-ended slot for permitting edgewise insertion thereinto of a flat leaf spring member, and b. an elongated spring metal member extending through said openings in said lugs in overlying relation to said base flange of said main bracket member, said spring member having spaced portions thereof resiliently biased to engage the inside surface of the jalousie louver when its aforesaid end is disposed in position between said base flange and said spring member, said spring member including means which coact with at least one of said slotted lugs to preclude shifting movement of said spring member longitudinally with respect to said bracket member when said spring member is interfitted in said lug openings.
Claim 11
Dependent Claim
