Abstract
Abstract A magnetic actuating mechanism for a pivotal venetian blind assembly. The mechanism includes a linear movable operating element in the form of a split housing operatively connected by connection means to a hanger pivot member supporting a plurality of slats. The split housing forms two housing sections each having a magnet therein. The hanger pivot member has a body portion the length of which is equal to a slat width and a bearing section spaced from an end slat.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
140 words
A magnetic actuating mechanism for a pivotal venetian blind assembly having a plurality of adjacent slats including an end slat at each end thereof, at least one tape cable forming a part of a supporting means supporting said slats, a hanger pivot member adapted to be pivotally mounted with respect to a frame member positioned adjacent each end slat of said plurality of slats supporting a tape cable therebetween, a linearly movable operating element, connecting means operably connecting said operating element with each hanger pivot member, a linearly movable operatable element and magnet means operatively connecting said operable element with said operating element, characterized in that said operating element comprises a split housing forming two similar housing sections, in that each housing section has a magnet therein and in that said housing is connected betwen said sections to connecting means.
Claim 2
Dependent Claim
140 words
A magnetic actuating mechanism for a pivotal venetian blind assembly having a plurality of adjacent slats including an end slat at each end thereof, at least one tape cable forming a part of a supporting means supporting said slats, a hanger pivot member adapted to be pivotally mounted with respect to a frame member positioned adjacent each end slat of said plurality of slats supporting a tape cable therebetween, a linearly movable operating element, connecting means operably connecting said operating element with each hanger pivot member, a linearly movable operatable element and magnet means operatively connecting said operable element with said operating element, characterized in that said operating element comprises a split housing forming two similar housing sections, in that each housing section has a magnet therein and in that said housing is connected betwen said sections to connecting means.
Claim 3
Dependent Claim
30 words
A magnetic acutating mechanism according to claim 1 further characterized in that said split housing is formed by a notch in said housing on a side thereof facing said slats.
Claim 4
Dependent Claim
28 words
A magnetic actuating mechanism according to claim 2 further characterized in that a plurality of slats adjacent said housing each have two cutouts therein to accommodate said sections.
Claim 5
Dependent Claim
19 words
A magnetic actuating mechanism according to claim 3 further characterized in that said connecting means comprises a tape cable.
Claim 6
Dependent Claim
36 words
A magnetic actuating mechanism according to claim 3 further characterized in that said slats adjacent said housing having said cutouts therein are connected to said cable at the widest part of said slats between said cutouts.
Claim 7
Dependent Claim
43 words
A magnetic actuating mechanism according to claim 1 further characterized in that said hanger pivot member comprises a body portion spaced from an end slat and in that the length of the body portion is substantially equal to the width of a slat.
Claim 8
Dependent Claim
57 words
A magnetic actuating mechanism according to claim 6 further characterized in that a tape cable extends over each longitudinal end of said body portion whereby when said hanger pivot member is pivoted with respect to a frame member, said slats will be tilted by a cable without lateral forces being exerted on said slats by the cable.
Claim 9
Dependent Claim
46 words
A magnetic actuating mechanism according to claim 7 further characterized in that a side of said body portion facing outwardly on an end slat has a plurality of slots therein through which tape cables may be threaded to fasten the same to said hanger pivot member.
Claim 10
Dependent Claim
131 words
A venetian blind hanger pivot member for a venetian blind having a plurality of adjacent slats including an end slat at one end thereof wherein said hanger pivot member is adapted to be pivotally mounted with respect to a frame member and tape cables forming part of a slat supporting means, characterized in that said hanger pivot member comprises a body portion spaced from said end slat, in that the length of said body portion is substantially equal to the width of said slats and in that said tape cables extend over the length of said body portion whereby when said hanger pivot member is pivoted with respect to a frame member, said slats will be tilted by said cables without lateral forces being exerted on said slats by said cables.
Claim 11
Dependent Claim
131 words
A venetian blind hanger pivot member for a venetian blind having a plurality of adjacent slats including an end slat at one end thereof wherein said hanger pivot member is adapted to be pivotally mounted with respect to a frame member and tape cables forming part of a slat supporting means, characterized in that said hanger pivot member comprises a body portion spaced from said end slat, in that the length of said body portion is substantially equal to the width of said slats and in that said tape cables extend over the length of said body portion whereby when said hanger pivot member is pivoted with respect to a frame member, said slats will be tilted by said cables without lateral forces being exerted on said slats by said cables.
Claim 12
Dependent Claim
48 words
A venetian blind hanger pivot member according to claim 9 further characterized in that a side of said body portion facing outwardly on said end slat has a plurality of slots therein through which tape cables may be threaded to fasten the same to said hanger pivot member.
Claim 13
Dependent Claim
40 words
A venetian blind hanger pivot member according to claim 9 further characterized in that said body portion has a bearing section on the side opposite thereof from said slots adapted to engage a suspension bracket connected to a frame member.
Claim 14
Dependent Claim
32 words
A venetian blind hanger pivot member according to claim 11 wherein said bearing section is spaced from an end slat a distance equal to substantially one-half the width of said end slat.
