Abstract
Abstract A unitary, one-piece vane carrier for vertical blinds is disclosed. The unitary carrier includes a carrier body and an elongated spacer link extending from one end of the body, the spacer link and body forming a single, unitary piece. In a disclosed embodiment, a tab is disposed at the distal end of the spacer link and a slotted opening is located in the end of the carrier body opposed to the end from which the spacer link extends. In that embodiment, the tab of one carrier cooperates with the slotted opening of an adjacently positioned carrier to limit the maximum spacing between the two carriers. The spacer link extends from the top of one end of the carrier body while the slotted opening is oppositely located at the top of the other end such that the spacer link of one carrier is slidable through the slotted opening of the adjacent carrier. Also in that disclosed embodiment, the spacer link includes a section of reduced width to facilitate insertion and removal of the spacer link into and from the slotted opening of an adjacent carrier and a section of reduced thickness to permit flexing of the spacer link thereat to facilitate stacking of the spacer links when the carriers are bunched.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
214 words
A unitary, one-piece carrier for vertical blinds comprising: a carrier body having spaced ends and spaced sides which form an enclosure for housing means for rotatably supporting a blind vane; an elongated flexible spacer link extending outwardly of said carrier body from a first end thereof and having an enlarged portion at the distal end thereof, said body and said spacer link forming a single, homogeneous, unitary piece; a receptacle located in a second end of the body at a location approximately opposed and in line with the first end from which said spacer link extends, said receptacle being of a width adapted to receive the spacer link of a next adjacent carrier therein in a sliding relation and including retaining means for retaining the spacer link of the next adjacent carrier therein; first camming means disposed on said spacer link at the distal end thereof and second camming means cooperating therewith disposed on the first end of said carrier body adjacent said spacer link for camming the spacer link of the next adjacent carrier over said first end of said body; and stop means disposed adjacent said receptacle for engaging the enlarged portion of the spacer link of the next adjacent carrier to prevent the enlarged portion thereof from being axially withdrawn therethrough.
Claim 2
Dependent Claim
214 words
A unitary, one-piece carrier for vertical blinds comprising: a carrier body having spaced ends and spaced sides which form an enclosure for housing means for rotatably supporting a blind vane; an elongated flexible spacer link extending outwardly of said carrier body from a first end thereof and having an enlarged portion at the distal end thereof, said body and said spacer link forming a single, homogeneous, unitary piece; a receptacle located in a second end of the body at a location approximately opposed and in line with the first end from which said spacer link extends, said receptacle being of a width adapted to receive the spacer link of a next adjacent carrier therein in a sliding relation and including retaining means for retaining the spacer link of the next adjacent carrier therein; first camming means disposed on said spacer link at the distal end thereof and second camming means cooperating therewith disposed on the first end of said carrier body adjacent said spacer link for camming the spacer link of the next adjacent carrier over said first end of said body; and stop means disposed adjacent said receptacle for engaging the enlarged portion of the spacer link of the next adjacent carrier to prevent the enlarged portion thereof from being axially withdrawn therethrough.
Claim 3
Dependent Claim
16 words
The carrier recited in claim 1, wherein said unitary, one-piece carrier comprises a hollow molded member.
Claim 4
Dependent Claim
15 words
The carrier recited in claim 2, wherein said carrier is molded of a plastic material.
Claim 5
Dependent Claim
13 words
The carrier recited in claim 3 wherein said carrier is molded of Nylon.
Claim 6
Dependent Claim
41 words
The carrier recited in claim 1, wherein said enlarged portion of said spacer link is in the form of a tab which is larger than the width of said receptacle such that said tab cannot be axially withdrawn through said receptacle.
Claim 7
Dependent Claim
82 words
The carrier recited in claim 5, wherein: said spaced link is generally flat and of generally rectangular cross-section having a width substantially larger than its thickness; said tab exceeds the width of said spacer link; said receptacle is of generally rectangular cross-section having a width which is larger than the width of said spacer link but is smaller than that of said tab; and said retaining means overlaps said receptacle at least in part and comprises tab means extending above said receptacle.
Claim 8
Dependent Claim
97 words
The carrier recited in claim 6, wherein said tab means define an opening having a width that is less than the width of said receptacle, and wherein said spacer link includes a smoothly-contoured section having a reduced material content located proximate the first end of the carrier body from which it extends, said section being normally slightly greater in size than that of said opening, said section being reducible in cross-sectional size by the application of force to said spacer link, whereby said spacer link may be inserted in and removed from said receptacle through said opening.
Claim 9
Dependent Claim
46 words
The carrier recited in claim 7 wherein said reduced material section is a section of reduced width, said width being slightly greater than the width of said opening, whereby said spacer link may be inserted and removed from said receptacle through said opening by flexing thereof.
Claim 10
Dependent Claim
99 words
The carrier recited in claim 1, wherein said carrier body is generally hollow and has a bottom, communicating axial openings in said first and seconds ends of said carrier body, and another opening in the bottom of said carrier body, the hollow interior of said carrier body and the axial and other openings being adapted to house a worm, a meshing worm wheel and vane supporting means for rotatably supporting a blind vane, the axial openings being adapted to rotatably retain the worm, and the other opening being adapted to rotatably retain the worm wheel and vane supporting means.
Claim 11
Dependent Claim
23 words
The carrier recited in claim 9 and including means disposed along sides of said body for slidably mounting said body in track means.
Claim 12
Dependent Claim
50 words
The carrier recited in claim 1, wherein said spacer link includes at least one section of reduced material content located adjacent to the first end of said carrier body to permit said spacer link to be flexed transverse to the axis of the spacer link adjacent to the first end.
Claim 13
Dependent Claim
55 words
The carrier recited in claim 1 and including means disposed along the sides of said body proximate the bottom thereof for movably mounting said body in track means and securing means comprising a plurality of openings for securing a cord to said body whereby movement of said cord moves said carrier along said track means.
Claim 14
Dependent Claim
59 words
The carrier recited in claim 1, wherein said first and second camming means comprise cooperating inclined surfaces disposed on the distal end of said spacer link and on said first end, said inclined surfaces being cooperatively operative to cam the distal end of the spacer link of the next adjacent carrier over the first end of said carrier body.
Claim 15
Dependent Claim
71 words
The carrier recited in claim 13 and including another inclined surface disposed on the top of the second end of said carrier body for assisting the spacer link of the next adjacent carrier to be slid thereover, said other inclined surface operatively cooperating with the inclined surface on the distal end of the spacer link of the next adjacent carrier to cam it over the second end of the carrier body.
Claim 16
Dependent Claim
32 words
The carrier as recited in claim 1, wherein the width of said receptacle is sized to stablize and guide the spacer link of the next adjacent carrier as it is slid therein.
