Description
CROSS-REFERENCE TO RELATED APPLICATIONS
This application corresponds to and claims priority to European Application Nos. 98203694.9, filed Nov. 3, 1998; 98200368.1, filed Feb. 11, 1999; and 99202210.3, filed Jul. 7, 1999. These European applications are hereby incorporated by reference as though fully set forth herein.
BACKGROUND OF THE INVENTION
a. Field of the Invention
This invention relates to a holder for a vertical section of an architectural covering, such as a drape or a vaned fabric for covering an architectural opening, like a window or door. This invention particularly relates to a holder for vertically arranged louvers of a louvered Venetian blind.
b. Background Art
Vertical Venetian blinds have generally been provided with a horizontally-extending head rail, in which there have been several carriers that can be moved along the length of the head rail. Each carrier has typically supported a vertically-extending louver in such a manner that the consumer of the Venetian blind could move the louver along the length of the head rail and also could rotate the louver about its vertical axis. For example, carriers have each included a drive hub of a gear wheel driven by a worm gear, and the drive hub has supported a depending louver holder that has been adapted to support securely the top portions of a louver while the carrier has been moving and turning the louver holder and the louver. See U.S. Pat. No. 4,335,775.
Different types of louver holders have been provided in carriers for vertical Venetian blinds. For example, louver holders have held upper marginal portions of louvers between their pairs of downwardly-extending pinching fingers. See German Gebrauchsmuster 85 23 104, German Offenlegungschrift 27 15 018 and U.S. Pat. No. 4,869,309. Louver holders have also held upper marginal portions of louvers on hooks that are provided on their downwardly-extending fingers and that extend through apertures in the upper marginal portions of the louvers. See U.S. Pat. No. 4,335,775. However, the grip of each of such louver holders on the upper marginal portions of the louvers has not always been sufficiently secure to suit the consumer. This has been a particular problem when louvers of different thicknesses of material have been used with the same holder and after louvers have had to be removed and replaced on the same holders.
There has continued to exist, therefore, a need for a holder which (i) is simple to make and install on a head rail, (ii) is simple to affix to a vertical section of an architectural covering and subsequently to detach from the vertical section, and (iii) securely affixes the vertical section to the head rail when the holder is used to move the vertical section along the length of the head rail or to rotate the section about its vertical axis.
BRIEF SUMMARY OF THE INVENTION
In accordance with this invention, a holder is provided for suspending a vertical section of an architectural covering from a carrier of a horizontally-extending head rail; the holder comprising:
a downwardly-extending first leg;
a generally downwardly-extending second leg that is pivotally connected to the first leg for movement between a first position, in which it extends substantially parallel to the first leg, and a second position, in which it is at an acute angle to the first leg;
the first leg having a first longitudinal side facing the second leg and the second leg having a second longitudinal side facing the first leg;
one of the first and second longitudinal sides, having a longitudinally extending first notch and the other of the first and second longitudinal sides having a first shoulder projecting generally perpendicularly therefrom so as to be received in the first notch when the second leg is in the first position;
the pivotal connection of the first and second legs extending laterally and being located above the first notch and the first shoulder; and
means on the first leg, above the pivotal connection, for attaching the first leg to the carrier.
In accordance with an advantageous aspect of the holder of the invention, the first leg has a longitudinally-elongate intermediate portion that is above the first notch and the first shoulder and that has a pair of laterally opposite sides, through which the pivotal connection (A) passes; and the second leg has two parallel arms which are above the first notch and the first shoulder and which extend longitudinally at least to the pivotal connection. It is especially advantageous that one of: i) the pair of laterally opposite sides of the intermediate portion and ii) facing lateral side portions of the two parallel arms have a pair of recesses about the pivotal connection; and the other one of: i) the pair of laterally opposite sides of the intermediate portion and ii) facing lateral side portions of the two parallel arms have a pair of laterally-extending pivots along the pivotal connection; each pivot being laterally inserted in one of the recesses.
It is particularly advantageous that each parallel arm carries one of the pivots and has a longitudinal end with a polygonal, particularly rectangular, longitudinal profile, and each recess is vertically elongated whereby the pivots can be moved to vertical extremities of the recesses, so as to move the second leg downwardly relative to the first leg when the first shoulder is in the first notch. It is quite particularly advantageous that the longitudinal side of each recess, remote from the second leg, is open and wherein longitudinally adjacent the open longitudinal sides of the pair of recesses are means for resiliently abutting against the longitudinal ends of the arms when the pivots are inserted in the recesses, advantageously an upwardly-extending spring, so that the pivots are prevented from moving longitudinally outwardly of the recesses through their open longitudinal sides. It is more quite particularly advantageous that a vertically-extending second notch is in the bottom of one of the first notch and the first shoulder and a vertically-extending second shoulder is on the bottom of the other of the first notch and the first shoulder; the second shoulder being adapted to be inserted vertically into the second notch, when the second leg is in the first position, by moving the second leg downwardly relative to the first leg, whereby the second leg is prevented from moving from the first position to the second position.
It is also particularly advantageous that each parallel arm carries one of the pivots, each recess is generally round and advantageously, on the bottom of the intermediate member of the first leg, adjacent an opposite longitudinal side of the second leg, are means for resiliently abutting against the opposite longitudinal side of the second leg when the pivots are in the recesses, especially a downwardly-extending leaf spring, so that the second leg is resiliently held in the first position. It is quite particularly advantageous that the spring extends downwardly to about the first notch and is longitudinally biased towards the first notch to keep the first shoulder of the second leg biased towards the first notch.
It is further particularly advantageous that each parallel arm carries one of the pivots, each recess is generally round and advantageously, on the arms and especially also between the arms, are means for resiliently abutting against a laterally-extending upper stop on the first leg, above the recesses, especially a cantilever spring that extends longitudinally and upwardly away from the first leg, so that the second leg is resiliently held in the first position. It is quite particularly advantageous that a lower portion of the spring separates and reinforces a laterally bifurcated, upper portion of the second leg, on which are the arms. It is more quite particularly advantageous that the spring is a laterally bifurcated, cantilever spring, each tine of which is upwardly biased towards one of a pair of the upper stops on laterally opposite sides of the first leg.
It is still further particularly advantageous that each parallel arm carries one of the pivots, each recess is generally round and advantageously a sloped surface on the first leg above its recesses, especially on each of its laterally opposite sides, particularly at least directly above each recess, is inclined upwardly and laterally outwardly between the arms, and a collar, especially with a generally semi-circular configuration, is on the second leg and has an interior surface, particularly on each of its laterally opposite sides, quite particularly at least directly above its pivots, which closely surrounds the sloped surface, so that the second leg is resiliently held in the first position. It is quite particularly advantageous that the sloped surface urges the interior surface of the collar and the arms to move laterally apart as the arms and the collar are pivoted about the recesses and pivots towards the second position.
In accordance with other aspects of the invention, a head rail for an architectural covering, such as a vertical blind, and an architectural covering are provided, comprising the holder, just described.
Further aspects of the invention will be apparent from the detailed description below of particular embodiments and the drawings thereof, in which:

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIGS. 1 and 2
show a vertical blind
1
having a plurality of vertical louvers
3
suspended from its horizontally-extending head rail
5
. The louvers
3
, shown in
FIGS. 1 and 2
, are conventional metal, plastic or fabric slats, each having an aperture
7
, which may be reinforced against tearing, in its upper marginal portion
9
. As described in detail below, each louver
3
is securely suspended vertically from one of a plurality of carriers, generally
11
, of the head rail
5
by means of a vertically-extending holder, generally
13
, of this invention. The holder
13
, which is preferably made of plastic, is attached to the carrier
11
and to the aperture
7
of the louver
3
as shown in FIG.
2
.
The head rail
5
, shown in
FIGS. 1 and 2
, is generally described in U.S. Pat. No. 4,335,775 and provides controlled longitudinal movement of the carriers
11
and the vertical louvers
3
along the length of the head rail and controlled rotation of the vertical louvers
3
about their vertical axes. In this regard, one longitudinal side of the head rail is provided with a conventional pull cord
15
that is connected to the carriers
11
for moving them longitudinally along the length of the headrail
5
. The one longitudinal side of the head rail
5
is also provided with a conventional bead chain
17
for rotating a longitudinally-extending drive shaft (not shown) of the head rail which can rotate a worm gear and its worm (not shown) within each carrier
11
so as to rotate the louvers
3
. The carriers
11
, as shown in
FIG. 2
, each have a pair of rollers
19
on opposite lateral sides of its housing
21
, so that the carriers can roll on longitudinally-extending tracks (not shown) on laterally opposite sides of the interior of the head rail
5
, along its length, in response to movement of the pull cord
15
. The housing
21
of each carrier
11
has a pair of openings
23
on its longitudinally opposite sides, through which the drive shaft (not shown) of the head rail
5
passes to frictionally engage the worm gear (not shown) within the housing
21
, so that rotation of the drive shaft causes rotation of the worm gear and thereby rotation of a drive gear
25
within the housing. A lower portion of the drive gear
25
includes a hollow vertically-extending hub (not shown), into which a vertically-extending upper part, generally
27
, of the holder
13
of this invention, as shown in
FIGS. 3-8
, can be inserted, so that the carrier
11
supports the holder
13
.
As shown in
FIGS. 3-8
, the upper part, generally
27
, of the holder
13
has a pair of spaced vertically-extending upper arms
29
on longitudinally opposite sides. The arms
29
are joined at the top by a generally rounded bracket
31
and are separated, beneath the bracket
31
, by an elongated laterally-extending slot
33
. At the upper ends of the upper arms
29
, below the bracket
31
, are a pair of wedge-like projections
35
, extending longitudinally in opposite directions. As in the vertical blind of U.S. Pat. No. 4,335,775, the upper part
27
of the holder
13
can be inserted into the hub of the drive gear
25
of each carrier
11
of the headrail
5
, so that the holder is securely attached to, and suspended vertically from, the headrail
5
and can move with longitudinal movement of the carrier and rotate with rotation of the drive gear.
As also shown in
FIGS. 3-8
, a vertically-extending lower part, generally
40
, of the holder
13
has a downwardly-extending first leg
42
and a generally downwardly-extending second leg
44
. An upper portion
45
of the first leg
42
of the lower part
40
of the holder
13
is rigidly fixed to the bottom of the upper part
27
of the holder, and the first leg
42
and the upper part
27
of the holder preferably comprise one piece. The first and second legs
42
and
44
are separate pieces that are pivotally connected, so that the second leg
44
can move relative to the first leg
42
between: a first or closed position shown in
FIGS. 3-5
, in which the second leg extends downwardly, substantially parallel to the first leg; and a second or open position, shown in
FIG. 6
, in which the second leg is at an acute angle to the first leg. The first and second legs
42
and
44
have first and second, longitudinal sides
46
and
48
, respectively, facing each other. A first, vertically elongate, longitudinally-extending notch
50
is provided in the first longitudinal side
46
of a lower portion
47
of the first leg
42
, and a first longitudinally-extending shoulder
52
projects generally perpendicularly from the second longitudinal side
48
of a lower portion
51
of the second leg
44
. Preferably, the upper portion
53
of the second leg
44
, above its longitudinally-extending shoulder
52
, is laterally bifurcated as seen in FIG.
8
. The longitudinally-extending shoulder
52
is adapted to be received in the longitudinally-extending notch
50
when the second leg
44
is in its closed position, substantially parallel to the first leg
42
and downwardly extending as shown in
FIGS. 2
,
3
-
5
and
7
. In this regard, the longitudinally-extending shoulder
52
of the second leg
44
of the carrier
13
can be inserted through the aperture
7
in the upper marginal portion
9
of a vertical louver
3
, before being received and held in the longitudinally-extending notch
50
in the first leg
42
of the carrier
13
, to securely support vertically the louver
3
from the headrail
5
of the vertical blind
1
.
The pivotal connection, generally A, of the second leg
44
to the first leg
42
of the lower part
40
of the holder
13
is best seen from FIG.
8
. This pivotal connection A extends laterally and is above the longitudinally-extending notch
50
and longitudinally-extending shoulder
52
of the first and second legs
42
,
44
. The pivotal connection A is provided by a pair of laterally spaced, parallel, lower arms
54
which are upper extensions of the laterally bifurcated, upper portion
53
of the second leg
44
, which are above the longitudinally-extending shoulder
52
of the second leg, and which extend generally longitudinally to a pair of elongate vertically-extending recesses
56
. The vertically-extending recesses
56
are located adjacent an opposite longitudinal side
46
A of the first leg
42
and in laterally opposite sides of a longitudinally-elongate intermediate portion
57
of the first leg
42
. The intermediate portion
57
is located above the longitudinally-extending notch
50
of the lower portion
47
of the first leg
42
and below its upper portion
45
. The longitudinal side of each vertically-extending recess
56
, along the opposite longitudinal side
46
A of the first leg
42
, remote from the second leg
44
, is preferably open. Upper portions of each vertically-extending recess
56
, on its other longitudinal side, closer to the second leg
44
, communicate with one of a pair of grooves
58
that are provided in the laterally opposite sides of the intermediate portion
57
of the first leg
42
, above its longitudinally-extending notch
50
, and that extend longitudinally along the entire length of the intermediate portion
57
. Facing lateral side portions
60
of the lower arms
54
of the second leg
44
face the vertically-extending recesses
56
and longitudinally-extending grooves
58
of the intermediate portion
57
of the first leg
42
and carry a pair of confronting, laterally-extending pivots
62
which are preferably round. The pivot
62
of each lower arm
54
is laterally inserted in one of the vertically-extending grooves
56
, so that the pivots
62
and the second leg
44
can freely rotate about the pivotal connection A when the pivots
62
are positioned in the upper portions of the vertically-extending recesses
56
of the first leg
42
as shown in
FIGS. 5 and 6
. Because the pair of vertically-extending recesses
56
of the first leg
42
are vertically elongated, the pivots
62
of the second leg
44
can be moved downwardly in these recesses, so as to move the second leg downwardly relative to the first leg
42
.
As also seen from
FIGS. 7 and 8
, the lateral side portions
60
and the pivots
62
of the second leg
44
are preferably adjacent to the longitudinal ends
64
of its lower arms
54
, remote from its second longitudinal side
48
. Each of the longitudinal ends
64
of the lower arms
54
preferably has a polygonal, especially a rectangular, longitudinal profile.
As further seen from
FIGS. 7 and 8
, an upwardly-extending leaf spring
66
is provided on top of the opposite longitudinal side
46
A of the first leg
42
, above its longitudinally-extending notch
50
. The spring
66
is longitudinally adjacent the open longitudinal sides of the vertically-extending recesses
56
and is longitudinally biased towards the vertically-extending recesses, so that the spring resiliently abuts against the longitudinal ends
64
of the lower arms
54
. As a result, the spring
66
keeps the pivots
62
on the lower arms
54
from moving longitudinally out of the vertically-extending recesses
56
, through their open longitudinal sides, particularly when the longitudinal ends
64
of the lower arms are moved longitudinally along the longitudinally-extending grooves
58
, towards the spring
66
, to insert their pivots
62
in the upper portions of the vertically-extending recesses
56
.
FIGS. 7 and 8
also show a pair of laterally-extending upper stops
68
and a pair of laterally-extending lower stops
70
, provided on laterally opposite sides of the first leg
42
, above and below its pairs of vertically-extending recesses
56
and longitudinally-extending grooves
58
. The lower stops
70
are adapted to abut against the bottom surfaces of the lower arms
54
to limit the downward movement of the pivots
62
of the lower arms in the vertically-extending recesses
56
as shown in FIG.
3
. The upper and lower stops
68
and
70
are also adapted to abut against the top and bottom surfaces respectively of the lower arms
54
to limit the upward pivoting of the lower arms
54
about their pivots
62
when the pivots are in the upper portions of the vertically-extending recesses
56
as shown in
FIGS. 5-6
. The lower stops
70
and the spring
66
are also adapted to abut against the bottom surfaces of the lower arms
54
and the longitudinal surfaces of their longitudinal ends
64
respectively to hinder upward pivoting of the lower arms
54
about their pivots
62
when the pivots are in the lower portions of the vertically-extending recesses
56
as shown in
FIGS. 3-4
.
As best seen from
FIG. 8
, a second vertically-extending notch
72
is provided in the bottom of the first longitudinally-extending shoulder
52
at about its lateral middle and preferably at about its longitudinal middle. As best seen from
FIG. 6
, a second vertically-extending shoulder
74
is provided on the bottom of the first longitudinally-extending notch
50
at about its lateral middle, preferably adjacent the first longitudinal side
46
of the first leg
42
. The vertically-extending shoulder
74
is adapted to be inserted vertically into the vertically-extending notch
72
when the longitudinally-extending shoulder
52
is in the longitudinally-extending notch
50
and the first and second legs
42
and
44
are closed as shown in
FIGS. 3-5
and
7
. Inserting the vertically-extending shoulder
74
vertically into the vertically-extending notch
72
can be accomplished simply by moving the second leg
44
downwardly relative to the first leg
42
as shown starting in FIG.
5
and ending in FIG.
3
. This can be easily done because the pivots
62
of the lower arms
54
of the second leg
44
can be moved downwardly in the vertically-extending recesses
56
of the first leg
42
, so as to move the second leg downwardly relative to the first leg, when the longitudinally-extending a shoulder
52
is in the longitudinally-extending notch
50
and the first and second legs
42
and
44
are closed.
Inserting the vertically-extending shoulder
74
vertically into the vertically-extending notch
72
serves to lock the longitudinally-extending shoulder
52
in the longitudinally-extending notch
50
and thereby to lock the first and second legs
42
and
44
of the holder
13
in the closed position shown in FIG.
3
. In this regard, the lower stops
70
and the spring
66
of the first leg
42
of the holder abut against the bottom surfaces of the lower arms
54
and the longitudinal surfaces of their longitudinal ends
64
to hinder upward pivoting of the lower arms
54
about their pivots
62
in the closed position of the holder. As a result, the holder
13
, in its closed position, can securely hold the louver
3
in a vertically extended position from the carrier
11
of the head rail
5
, with the longitudinally-extending shoulder
52
of the holders second leg
44
being inserted into the aperture
7
in the upper marginal portion
9
of the louver and then into the longitudinally-extending notch
50
of the first leg
42
.
As also best seen from
FIG. 8
, a guide member
76
extends downwardly from the longitudinal end of the intermediate member
57
of the first leg
42
, remote from the vertically-extending recesses
56
. The guide member
76
fits closely between the two parts of the laterally bifurcated, upper portion
53
of the second leg
44
and serves to maintain their separation when the second leg pivots relative to the first leg
42
from its open position to its closed position.
FIGS. 9-16
show a second embodiment of a holder
113
of the invention, which is similar to the holder
13
of
FIGS. 1-8
and for which corresponding reference numerals (greater by 100) are used below for describing the corresponding parts.
FIG. 9
shows a vertical louver, generally
103
, of a vertical blind
101
(not shown). The louver
103
is securely suspended from a carrier, generally
111
, of a head rail
105
(not shown) by means of a vertically-extending holder
113
which is attached to the carrier
111
and to an aperture
107
in the upper marginal portion
109
of the louver.
FIGS. 10-16
show an upper part
127
of the holder
113
and a vertically-extending lower part
140
of the holder, holding the louver
103
. The lower part
140
of the holder
113
has pivotally-connected, first and second legs
142
,
144
which, as shown in
FIGS. 10 and 11
, can accommodate and securely hold a relatively thin louver
103
A or a relatively thick louver
103
B between them. An upper portion
145
of the first leg
142
is rigidly fixed to the bottom of the upper part
127
of the holder, and the first leg
142
and the upper part
127
of the holder preferably are one piece. A first vertically-elongate longitudinally-extending notch
150
is provided in a first longitudinal side
146
of a lower portion
147
of the first leg
142
, and a first longitudinally-extending shoulder
152
projects generally perpendicularly from a second longitudinal side
148
of a lower portion
149
of the second leg
144
. The first shoulder
152
is adapted to be received in the first notch
150
when the second leg
144
is in its closed position, substantially parallel to the first leg
142
and downwardly-extending as shown in
FIGS. 9
,
10
,
13
and
14
.
The pivotal connection, generally A, of the first and second legs
142
,
144
of the holder
113
is best seen from
FIGS. 15 and 16
. This pivotal connection A is provided by a pair of parallel lower arms
154
which are upper extensions of a laterally bifurcated, upper portion
153
of the second leg
144
, which are above its first shoulder
152
and which extend generally longitudinally to a pair of round or circular recesses
156
. The round recesses
156
are in laterally opposite sides of a longitudinally-elongate intermediate portion
157
of the first leg
142
, above its first notch
150
, and are adjacent an opposite longitudinal side
146
A of the first leg. The longitudinal side of each round recess
156
, along the opposite longitudinal side
146
A of the first leg
142
, remote from the second leg
144
, is closed. Each recess
156
, on its other longitudinal side, closer to the second leg
144
, communicates with one of a pair of longitudinally-extending grooves
158
in laterally opposite sides of the intermediate portion
157
of the first leg
142
. A laterally-extending, preferably round pivot
162
of each lower arm
154
is laterally inserted in one of the recesses
156
, so that the pivots
162
and the second leg
144
can freely rotate about the pivotal connection A and relative to the first leg
142
as shown in
FIGS. 10-12
.
As also seen from FIGS.
10
and
14
-
16
, a leaf spring
166
extends downwardly from the longitudinal end of the intermediate portion
157
of the first leg
142
, remote from the round recesses
156
and adjacent an opposite longitudinal side
148
A of the second leg
144
. The spring
166
is parallel to the first longitudinal side
146
of the first leg and extends downwardly to about the first notch
150
. The spring
166
is longitudinally biased towards the first notch
150
, so that the spring resiliently abuts against the opposite longitudinal side
148
A of the second leg
144
. As a result, the spring
166
keeps the first shoulder
152
of the second leg
144
biased longitudinally towards the first notch
150
of the first leg
142
, thereby keeping the second leg
144
biased longitudinally towards the first leg
142
and biased towards the closed position of the holder
113
. In this regard, the spring
166
can serve to keep different thicknesses of louver
103
clamped securely between the legs
142
,
144
(see
FIGS. 10-12
) and also to restrain swivelling of the louver about its vertical axis.
Preferably, the longitudinally-extending first shoulder
152
extends upwardly somewhat towards the first leg
142
in a closed position of the holder
113
as shown in
FIGS. 10-11
. Thereby, once the upper marginal portion
109
of the louver
103
is inserted between the legs
142
,
144
and the first shoulder
152
is inserted through the aperture
107
in the upper marginal portion of the louver, the weight of the louver on the first shoulder will cause the second leg
144
to be biased towards the first leg
142
. This will cause the first shoulder to be urged inwardly of the longitudinally-extending first notch
150
and will further bias the second leg
144
towards the closed position of the holder
113
.
As further seen from FIGS.
12
and
14
-
16
, a guide member
176
extends downwardly from the intermediate portion
157
of the first leg
142
, between the recesses
156
and the spring
166
. The guide member
176
fits closely between the two parts of the laterally bifurcated, upper portion
153
of the second leg
144
and serves to maintain their separation when the second leg pivots relative to the first leg
142
from its open position to its closed position.
As still further seen from
FIGS. 10-16
, a pair of laterally-extending upper stops
168
are provided on laterally opposite sides of the upper portion
145
of the first leg
142
, above its pairs of recesses
156
and grooves
158
. The upper stops
168
are adapted to abut against the top surfaces of the lower arms
154
to limit their upward pivoting about the pivots
162
as shown in FIG.
12
. In this regard, an upstanding laterally-extending ridge
167
is provided on top of each lower arm
154
. The ridges
167
are adapted to abut against the upper stops
168
, so as to limit further the upward pivoting of the lower arms about the pivots
162
.
In addition, the spring
166
of the first leg
142
also abuts against the opposite longitudinal side
148
A of the second leg
144
to hinder its upward pivoting by continuously urging it longitudinally towards the first leg. As a result, the second leg
144
is continuously biased downwardly to the closed position of the holder
113
where it can securely hold the louver
103
in a vertically extended position from the carrier
111
of the head rail
105
, with the first shoulder
152
of the holders second leg
144
being inserted longitudinally into the aperture
107
in the upper marginal portion
109
of the louver and then into the first notch of the first leg
142
.
FIGS. 17-24
show a third embodiment of a holder
213
of the invention, which is similar to the holder
13
of
FIGS. 1-8
and for which corresponding reference numerals (greater by 200) are used below for describing the corresponding parts.
FIG. 17
shows a vertical louver, generally
203
, of a vertical blind
201
(not shown). The louver
203
is securely suspended from a carrier, generally
211
, of a head rail
205
(not shown) by means of the vertically-extending holder
213
which is attached to the carrier
211
and to an aperture
207
in the upper marginal portion
209
of the louver.
FIGS. 18-24
show an upper part
227
of the holder
213
, held by the carrier
211
, and a vertically-extending lower part
240
of the holder
213
, holding the louver
203
. The lower part
240
has pivotally-connected, first and second legs
242
,
244
which, as shown in
FIGS. 18 and 19
, can accommodate and securely hold a relatively thin louver
203
A or a relatively thick louver
203
B between them. An upper portion
245
of the first leg
242
of the holder
213
is rigidly fixed to the bottom of the upper part
227
of the holder, and the first leg
242
and the upper part
227
of the holder preferably comprise one piece. A first vertically-elongate longitudinally-extending notch
250
is provided in a first longitudinal side
246
of a lower portion
247
of the first leg
242
, and a first longitudinally-extending shoulder
252
projects generally perpendicularly from a second longitudinal side
248
of a lower portion
249
of the second leg
244
. The first shoulder
252
is adapted to be received in the first notch
250
when the second leg
244
is in its closed position, substantially parallel to the first leg
242
and downwardly-extending as shown in
FIGS. 17
,
18
,
21
and
23
.
The pivotal connection, generally A, of the first and second legs
242
,
244
of the holder
213
is best seen from
FIGS. 21-24
. This pivotal connection A is provided by a pair of parallel lower arms
254
which are upper extensions of a laterally bifurcated, upper portion
253
of the second leg
244
, which are above the first shoulder
252
, and which extend generally longitudinally to a pair of round or circular recesses
256
. The round recesses
256
are in laterally opposite sides of a longitudinally-elongate intermediate portion
257
of the first leg
242
, above its first notch
250
, and are adjacent an opposite longitudinal side
246
A of the first leg. The longitudinal side of each recess
256
, along the opposite longitudinal side
246
A of the first leg
242
, remote from the second leg
244
, is closed. Each recess
256
, on its other longitudinal side, closer to the second leg
244
, communicates with one of a pair of longitudinally-extending grooves
258
in laterally opposite sides of the intermediate portion
257
of the first leg
242
. A laterally-extending, preferably round pivot
262
of each lower arm
254
is laterally inserted in one of the recesses
256
, so that the pivots
262
and the second leg
244
can freely rotate about the pivotal connection A and relative to the first leg
242
as shown in
FIGS. 18-20
.
As also seen from
FIGS. 18-20
,
21
and
23
, a laterally bifurcated, cantilever spring
266
is provided on, and preferably between, the lower arms
254
on the laterally bifurcated, upper portion
253
of the second leg
244
. The spring
266
extends longitudinally and upwardly away from the first leg
242
. In this regard, a lower or base portion
267
of the spring
266
separates and reinforces the upper portion
253
of the second leg
244
. As seen from
FIGS. 23 and 24
, the base portion
267
of the spring preferably has a generally semi-circular configuration in horizontal cross-section, forming a collar that surrounds the upper portion
245
of the first leg
242
, directly above its recesses
256
and grooves
258
. The top of the spring
266
is adjacent to a pair of laterally-extending upper stops
268
on laterally opposite sides of a the upper portion
245
of the first leg
242
, above its recesses
256
and grooves
258
. Each tine of the bifurcated spring
266
is upwardly biased towards one of the upper stops
268
, so that the spring urges the second leg
244
towards the first leg
242
. As a result, the spring
266
keeps the first shoulder
252
of the second leg
244
biased longitudinally towards the first notch
250
of the first leg
242
, thereby keeping the second leg biased towards the closed position of the holder
213
. In this regard, the spring
266
can serve to keep different thicknesses of louver
203
clamped securely between the legs
242
,
244
(see
FIGS. 18-20
) and also to restrain swivelling of the louver about its vertical axis.
Preferably, the tines of the bifurcated spring
266
are upwardly biased against the upper stops
268
on the first leg
242
, even in the most closed position of the holder
213
, shown in FIG.
18
. Thereby, the spring
266
is always urging the second leg
244
towards the first leg
242
and towards the closed position of the holder
213
. As a result, the legs
242
,
244
have to be pried apart in order to insert the upper marginal portion
209
of the louver
203
between them and to hook the aperture
207
on the first shoulder
252
.
It is also preferred that the first shoulder
252
extend upwardly somewhat towards the first leg
242
in a closed position of the holder
213
as shown in
FIGS. 18-19
. Thereby, once the upper marginal portion
209
of the louver
203
is inserted between the legs
242
,
244
and the first shoulder
252
is inserted through the aperture
207
in the upper marginal portion of the louver, the weight of the louver on the first shoulder will cause the second leg
244
to be biased towards the first leg
242
. This will cause the first shoulder to be urged inwardly of the first notch
250
and will further bias the second leg
244
towards the closed position of the holder
213
.
As further seen from
FIGS. 23 and 24
, a guide member
276
extends downwardly from the intermediate portion
257
of the first leg
242
, between the round recesses
256
. The guide member
276
fits closely between the two parts of the laterally bifurcated, upper portion
253
of the second leg
244
and serves to maintain their separation when the second leg pivots relative to the first leg
242
from its open position to its closed position.
FIGS. 25-30
show a fourth embodiment of a holder
313
of the invention, which is similar to the holder
13
of
FIGS. 1-8
and for which corresponding reference numerals (greater by 300) are used below for describing the corresponding parts.
FIG. 25
shows a vertical louver, generally
303
, of a vertical blind
301
(not shown). The louver
303
is securely suspended from a carrier, generally
311
, of a head rail
305
(not shown) by means of the vertically-extending holder
313
which is attached to the carrier
311
and to an aperture
307
in the upper marginal portion
309
of the louver.
FIGS. 26-30
show an upper part
327
of the holder
313
, held by the carrier
311
, and a vertically-extending lower part
340
of the holder
313
, holding the louver
303
. The lower part
340
of the holder
313
has pivotally-connected, first and second legs
342
,
344
which, as shown in
FIGS. 26 and 27
, can accommodate and securely hold a relatively thin louver
303
A or a relatively thick louver
303
B between them. An upper portion
345
of the first leg
342
of the holder
313
is rigidly fixed to the bottom of the upper part
327
of the holder. A first vertically-elongate longitudinally-extending notch
350
is provided in a first longitudinal side
346
of a lower portion
347
of the first leg
342
, and a first longitudinally-extending shoulder
352
projects generally perpendicularly from a second longitudinal side
348
(not shown) of a lower portion
349
of the second leg
344
. The first shoulder
352
is adapted to be received in the first notch
350
when the second leg
344
is in its closed position, substantially parallel to the first leg
342
and downwardly-extending as shown in
FIGS. 25
,
26
and
29
.
The pivotal connection, generally A, of the first and second legs
342
,
344
of the holder
313
is best seen from
FIGS. 29-30
. This pivotal connection A is provided by a pair of parallel lower arms
354
which are upper extensions of a laterally bifurcated, upper portion
353
of the second leg
344
, which are above the first shoulder
352
of the second leg, and which extend generally longitudinally to a pair of round or circular recesses
356
. The round recesses
356
are in laterally opposite sides of a longitudinally-elongate intermediate portion
357
of the first leg
342
, above its first notch
350
, and are adjacent an opposite longitudinal side
346
A (not shown) of the first leg. The longitudinal side of each recess
356
, along the opposite longitudinal side
346
A of the first leg
342
, remote from the second leg
344
, is closed. Each recess
356
, its other longitudinal side, closer to the second leg
344
, communicates with one of a pair of longitudinally-extending grooves
358
in laterally opposite sides of the intermediate portion
357
of the first leg
342
. A laterally-extending, preferably round pivot
362
(not shown) of each lower arm
354
is laterally inserted in one of the recesses
356
, so that the pivots and the second leg
344
can freely rotate about the pivotal connection A and relative to the first leg
342
as shown in
FIGS. 26-28
.
As best seen from
FIGS. 29-31
, the upper portion
345
of the first leg
342
has a sloped surface
366
above its recesses
356
, preferably on each lateral side of the first leg, particularly at least directly above each recess
356
. Each sloped surface
366
is inclined upwardly and laterally outwardly, between the lower arms
354
on the laterally bifurcated, upper portion
353
of the second leg
344
. In addition, a collar
367
, preferably with a generally semi-circular configuration, is provided on the upper portion
353
of the second leg
344
to separate and reinforce the upper portion of the second leg. The interior surface
369
of the collar
367
closely surrounds each sloped surface
366
of the upper portion
345
of the first leg
342
. Preferably, at least laterally opposite sides of the interior surface
369
of the collar
367
closely surround a pair of sloped surfaces
366
on laterally opposite sides of the first leg
342
, particularly at least directly above the pivots
362
(not shown) of the second leg
344
. The interaction between each sloped surface
366
of the first leg
342
and the surround interior surface
369
of the collar
367
of the second leg
344
keeps the first shoulder
352
of the second leg biased longitudinally towards the first notch
350
of the first leg, thereby keeping the second leg biased towards the closed position of the holder
313
. In this regard, each sloped surface
366
of the first leg
342
urges i) the interior surface
369
of the collar
367
on the second leg
344
, preferably at least laterally opposite sides of the interior surface of the collar, particularly at least directly above the pivots
362
, and ii) also the lower arms
354
, attached to the collar, to move laterally apart as the lower arms and the collar are pivoted about the recesses
356
and pivots
362
towards the open position of the holder
313
—against the inherent resistance of the material to (preferably plastic), from which the second leg
344
is made. Such inherent resistance of the collar
367
and the lower arms
354
to being laterally spread apart, when the interior surface
369
of the collar is moved upwardly along each sloped surface
366
of the first leg to open the holder
313
, serves to keep the holder closed. Thereby, the closed holder
313
clamps different thicknesses of louver
303
securely between its legs
342
,
344
(see
FIGS. 26-28
) and keeps the louver from swivelling about its vertical axis.
Preferably, the interior surface
369
of the collar
367
on the second leg
344
is biased against each sloped surface
366
of the upper portion
345
of the first leg
342
, even in the most closed position of the holder
313
. Thereby, the collar
367
is always urging the second leg
344
towards the first leg
342
to keep the holder
313
closed. As a result, the legs
342
,
344
have to be pried apart in order to insert the upper marginal portion
309
of the louver
303
between them and to hook the aperture
307
on the longitudinally-extending shoulder
352
.
It is believed that the angle of the upward and laterally outward inclination of each sloped surface
366
and the separation of each sloped surface
366
from the surrounding interior surface
369
of the collar
367
, especially on laterally opposite sides of the collar, particularly directly above the recesses
356
and pivots
362
, are not critical and can be varied, so long as the collar
367
is always urging the second leg
344
towards the first leg
342
and the closed position of the holder
313
.
It is also preferred that the first shoulder
352
extend upwardly somewhat towards the first leg
342
in a closed position of the holder
313
as shown in
FIGS. 26
and
29
. Thereby, once the upper marginal portion
309
of the louver
303
is inserted between the legs
342
,
344
and the first shoulder
352
is inserted through the aperture
307
in the upper marginal portion of the louver, the weight of the louver on the first shoulder will cause the second leg
344
to be biased towards the first leg
342
. This will cause the first shoulder to be urged inwardly of the first notch
350
and will further bias the second leg
344
towards the closed position of the holder
313
.
As further seen from
FIGS. 29 and 30
, a guide member
376
extends downwardly from the intermediate portion
357
of the first leg
342
, between the recesses
356
. The guide member
376
fits closely between the two parts of the laterally bifurcated, upper portion
353
of the second leg
344
and serves to maintain their separation when the second leg pivots relative to the first leg from its open position to its closed position.
This invention is, of course, not limited to the above-described embodiments which may be modified without departing from the scope of the invention or sacrificing all of its advantages. In this regard, the terms in the foregoing description and the following claims, such as “longitudinal”, “lateral”, “above”, “below”, “top”, “bottom”, “vertical”, “horizontal”, “upwardly” and “downwardly”, have been used only as relative terms to describe the relationships of the various elements of the holder of the invention for vertical sections of architectural coverings. In this regard, the vertical louvers
3
,
103
,
203
,
303
of the vertical blinds
1
,
101
,
201
,
301
could be replaced by other vertical sections of an architectural covering, for example; i) by vertical sections of a conventional drapery fabric having apertures in its upper marginal portion, through which the longitudinally-extending shoulders
52
,
152
,
252
,
352
of the holders
13
,
113
,
213
,
313
can be inserted; or ii) by vertical sections of a vaned fabric as described in PCT publication WO 96/35854, each vertical section having an aperture in the upper marginal portion of the hanger plate in each vane, through which the longitudinally-extending shoulders
52
,
152
,
252
,
352
of the holders
13
,
113
,
213
,
313
can be inserted; or iii) by vertical vanes as described in PCT publication WO 96/35881, each vane having an aperture in the upper marginal portion of its hanger plate, through which the longitudinally-extending shoulders
52
,
152
,
252
,
352
of the holders
13
,
113
,
213
,
313
can be inserted.
Likewise, the head rail
5
,
105
,
205
,
305
could be replaced by a conventional head rail or by one especially adapted to provide improved control of movement of the vertical louvers
3
