Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 135 words
In a transport apparatus for vertical venetian blinds or drapes, having one or more sections, which comprises in combination, a horizontal support, movable carriers which move along the support and carry vertical vanes or drapes and moving means which engage the movable carriers and move the movable carriers along the support the improvement which comprises; providing a vertical venetian blind or drape which can be opened in either direction across a section without rearrangement of the apparatus by releaseably engaging at least the end movable carriers, in each section, with the moving means and providing stops, disposed at the limits of travel in the section to engage a movable carrier, releaseably engaged with the moving means, to release the engagement with the moving means as the movable carrier is moved into engagement with a stop.
Claim 2
Dependent Claim 135 words
In a transport apparatus for vertical venetian blinds or drapes, having one or more sections, which comprises in combination, a horizontal support, movable carriers which move along the support and carry vertical vanes or drapes and moving means which engage the movable carriers and move the movable carriers along the support the improvement which comprises; providing a vertical venetian blind or drape which can be opened in either direction across a section without rearrangement of the apparatus by releaseably engaging at least the end movable carriers, in each section, with the moving means and providing stops, disposed at the limits of travel in the section to engage a movable carrier, releaseably engaged with the moving means, to release the engagement with the moving means as the movable carrier is moved into engagement with a stop.
Claim 3
Dependent Claim 42 words
In the apparatus of claim 1 the improvement which comprises; releaseably engaging each movable carrier with an indexing means disposed on the moving means, whereby a fixed relation is maintained between the movable carriers as the carriers are moved along the support.
Claim 4
Dependent Claim 51 words
In the apparatus of claim 1, wherein the movable carriers have vertical vanes rotatably mounted thereon, the improvement which comprises; providing the movable carriers with rotatable vane supports having a helical guide mounted thereon and providing means which engage and apply force to said helical guide whereby the vanes are rotated.
Claim 5
Dependent Claim 18 words
The apparatus of claim 3 wherein the helical guide is a helical slot in said rotatable vane support.
Claim 6
Dependent Claim 63 words
The apparatus of claim 4 wherein the movable carrier having mounted thereon the rotatable vane support is provided with a pin guide which accepts a pin one end of which engages the helical slot in the rotatable vane support and the opposite end engages a means which moves the pin along the pin guide in the movable carrier whereby the vanes are rotated.
Claim 7
Dependent Claim 46 words
In the apparatus of claim 2 adapted for vertical venetian blinds, the improvement which comprises; providing the movable carriers with rotatable vane supports having a helical guide mounted thereon and providing means which engage and apply force to said helical guide whereby the vanes are rotated.
Claim 8
Dependent Claim 64 words
In the apparatus of claim 6 wherein the movable carrier having mounted thereon the rotatable vane support is provided with a pin guide which accepts a pin one end of which engages the helical slot in the rotatable vane support and the opposite end engages a means which moves the pin along the pin guide in the movable carrier whereby the vanes are rotated.
Claim 9
Dependent Claim 98 words
The apparatus of claim 1 wherein the releaseably engaged movable carriers and moving means for moving the carriers along the support comprise a moving means, which is moved parallel to the movement of the movable carriers, having disposed thereon indexing means which releaseably engage the movable carrier, the movable carrier having a passage whereby the indexing means can pass the carrier and a blocking means to block said passage to engage the indexing means whereby the carrier is moved along the support, said blocking means releasing the engagement with the indexing means when the carrier engages the stop.
Claim 10
Dependent Claim 22 words
The carrier of claim 8 wherein the blocking means is positioned to block said passage by a magnet positioned in the carrier.
Claim 11
Dependent Claim 18 words
The carrier of claim 8 wherein the blocking means is positioned to block said passage by a spring.
Claim 12
Dependent Claim 117 words
The apparatus of claim 2 wherein the movable carriers and moving means for moving the carriers along the support comprises; a moving means, which is moved parallel to the movement to the movable carriers, having disposed thereon indexing means which releaseably engage the movable carriers, the movable carriers havIng a passage whereby the indexing means can pass the carriers, and a blocking means to block said passage to engage the indexing means whereby the carrier is moved along the support, said blocking means adapted to release the engagement with the indexing means when the carrier engages the stop and when the carrier is moved adjacent to a carrier which has released the engagement with the indexing means.
Claim 13
Dependent Claim 99 words
The apparatus of claim 3 wherein the movable carriers and moving means for moving the carriers along the support comprise; a moving means, which is moved parallel to the movement of the movable carriers, having disposed thereon indexing means which releasably engage the movable carriers, the movable carriers having a passage, whereby the indexing means can pass the carrier and a blocking means to block said passage to engage the indexing means whereby the carrier is moved along the support, said blocking means releasing the engagement of the carrier with the indexing means when the carrier engages the stop.
Claim 14
Dependent Claim 105 words
The apparatus of claim 6 which comprises; a moving means, which is moved parallel to the movement of the movable carriers, having disposed thereon indexing means which releaseably engage the movable carriers, the movable carriers having a passage whereby the indexing means can pass the carriers, and a blocking means to block said passage to engage the indexing means whereby the carrier is moved along the support, said blocking means releasing the engagement of the carrier with the indexing means when the carrier engages the stop and when the carrier is moved adjacent to a carrier which has released the engagement with the indexing means.
