[0001] The present invention relates to a screening arrangement having a supply condition
and a condition of use, comprising a top element extending in a first longitudinal
direction defining, in the condition of use, a width direction, said first longitudinal
direction being substantially perpendicular to a second longitudinal direction, two
side rails, each extending, in the condition of use, in the second longitudinal direction,
a screening device with a cord system, said screening device has a first end edge
and a second opposite end edge connected to a bottom element extending in the first
longitudinal direction, each end of the bottom element is provided with a side guidance
element having a cord protection section with a backside and a front side protecting,
in said supply condition, a cord of the cord system.
[0002] It is well known that in such screening arrangements the cords of the cord system
must be protected from the side rails as the side rails may have relatively sharp
end edges. Therefore, when the side rails are mounted on the top rail by a customer
or artisan at the customer's premises it is of high importance that the cords are
not exposed so that they come in contact with the end edges of the side rails.
[0003] A known solution to this problem is found in
WO2009/052822, which discloses a screening arrangement with a parallel guidance cord system wherein
the cords of the cord system is guided in openings positioned in an outer portion
of side guidance elements mounted on respective ends of a bottom element. In a supply
condition a cord of the cord system is guided and releasably fixed in an upstanding
wall portion protruding on the backside of a cord protection section, which is positioned
in a lower portion of the respective side guidance elements, and the cord is guided
from the backside of the cord protection section to a cord supply fitting.
[0004] With this in mind it is the object of the present invention to provide a screening
arrangement having a mechanically more simple construction that still allows the cord
system to be protected during installation of the side rails.
[0005] This and further objects are achieved by means of a screening arrangement of the
kind mentioned in the introduction, which is furthermore characterized in that in
said supply condition, the cord is guided from an outer portion of the side guidance
element along the backside of the cord protection section to an opening at an inner
portion of the side guidance element facing the bottom element.
[0006] In the supply condition, the cord protection section protects the cord from the side
rail so that an edge of the respective side rails does not come into contact with
the cords when they are guided by the respective side guidance elements. By guiding
the cord from an outer portion of the side guidance elements to an opening in the
inner portion of the side guidance element, which opening is positioned at the portion
of the side guidance elements facing the bottom element, a mechanically simple and
advantageous solution of guiding the cord along the side guidance elements is provided.
Hence the material consumption is reduced and the part of the side guidance element
guiding the cord and consequently the portion of the cord guided therein is less prone
to be damaged by the side rails during installation thereof on the top element.
[0007] In a preferred embodiment, in said supply condition, the cord is released from the
inner portion of the side guidance element at a distance d in the second longitudinal
direction from a lower edge of the bottom element or from a lower edge of the side
guidance element.
[0008] This ensures that the lower edge of the bottom element is position below the opening
at the inner portion of the side guidance element so that the blind properties are
not impaired, i.e. if the lower edges of the side guidance elements are flush with
the lower edge of the bottom element, the side guidance elements and the bottom element
will screen the full width between the side rails.
[0009] In a further developed embodiment of the invention, the side guidance element comprises
a further lower portion comprising a cord guide positioned at the outer portion of
the side guidance element and guiding, in the condition of use, the cord in the second
longitudinal direction.
[0010] Thereby the cords guided along the side guidance elements are even further protected
during installation of the side rails, and the further lower portion of the side guidance
elements may further serve to guide the cord in the condition of use. Especially the
outer portion of the side guidance elements at which the cords are likely to be exposed
during installation of the side rails is protected by the further lower portion, but
the provision of a further cord guide is also advantageously as it may provide more
guide friction between the side guidance elements and the cords of the cord system,
which is desirable in order to obtain a proper functioning of different type of cord
systems so that the bottom element may be moved to and kept at different positions
along the longitudinal direction of the screening arrangement. Moreover, the further
lower portion of the side guidance element may be configured with respect to a main
body portion of the side guidance element so that when the cord is guided from the
outer portion to the inner portion of the side guidance element, the cord is also
protected on the backside of the side guidance element. Hence even if the side guidance
element is guided in a guide means such as a track of the side rails before the cords
are released form the supply condition, the cords are duly protected from the side
rails.
[0011] Additionally, the mechanically more simple solution according to the invention also
allows the user to see how the cords are guided along the side guidance elements in
the supply condition so that it is readily understood how the cords should be released
from the cord protection section during installation.
[0012] In a preferred embodiment which provides for a flush surface for abutting against
a guide track of the side rails and which still allows the cord to be protected, the
cord protecting section forms part of a front side of the side guidance element and
the cord is guided, in the supply condition, on the backside of the side guidance
element and released from an opening in the inner portion of the front side of the
side guidance element. The opening may be positioned at a distance d from the lower
edge of the bottom element or from the lower edge of the side guidance element.
[0013] Such configuration of the cord protection section and the front surface of the side
guidance element also provide a mechanically simple construction protecting the cord
both during installation and in the condition of use.
[0014] More specifically it is advantageous if, in the condition of use, an edge of the
side rails extending in the second longitudinal direction and being adapted to guide
the side guidance element extend across the front side the cord protection section.
[0015] Then the cord is protected during installation from any possible sharp edge of for
instance a guide track of the side rails adapted to guide the side guidance elements
in the condition of use.
[0016] In a further developed embodiment, the side guidance element comprises a first rib
section extending away from the bottom element in the first longitudinal direction,
said first rib section has a free distal end and a proximal end connected to the outer
section of the side guidance element, and the side guidance element comprises a second
rib section extending away from the bottom element in the first longitudinal direction,
said second rib section has a free distal end and a proximal end connected to the
outer section of the side guidance element.
[0017] This makes is easier to mount the cords of the cord system on the side guidance elements
and guide them along or in the bottom element to and from the respective ends of the
top element so that they can be stored and guided by a cord supply fitting in the
supply condition or mounted at a lower corner of a sash in the condition of use, respectively.
Moreover, the rib section provides and increased friction between the cords of the
cord system and the side guidance elements so that the bottom element may be moved
to and kept in a position along a longitudinal direction of the side rails.
[0018] In a further development which is especially useful for a parallel guidance cord
system, the first rib section guides a cord received from the corresponding end of
the top element, and the second rib section guides a cord received from the opposite
end of the top element.
[0019] In an even further development of the invention, the side guidance element comprises
an intermediate rib section extending away from the side guidance element in the first
longitudinal direction between the first and second rib sections, said intermediate
rib section has a free distal end and a proximal end connected to the outer section
of the side guidance element.
[0020] A further rib section provides more friction between the cord and the side guidance
elements, while the cord is guided from an upper part of the side guidance element
to a lower part of the side guidance element where the cord, in the supply condition
and partly during installation, may be guided to and stored in a cord supply fitting.
[0021] In an embodiment which is especially suitable for a parallel guidance cord system,
the intermediate rib section guides a cord received from the opposite end of the top
element.
[0022] In the following the invention will be described in further detail by means of examples
of embodiments with reference to the schematic drawings, in which
Fig. 1 is a perspective view of a screening arrangement in an embodiment of the invention,

of the screening arrangement shown in Fig. 1,
Fig. 3 shows, on a larger scale, a partial perspective view of an embodiment according
to the invention,
Fig. 4 shows, on a larger scale, a partial perspective view of another embodiment
according to the invention,
Fig. 5 shows a different perspective view of the embodiment shown in Fig. 4.
[0023] Fig. 1 shows an embodiment of a screening arrangement 1 according to the invention.
The screening arrangement 1 is adapted to be mounted on a frame or a sash representing
a window. It is noted that the terms "sash" or "frame" is to be understood as incorporating
any substantially rectangular structure positioned in any opening in a building, whether
in a wall or the roof, and surrounding an aperture to be screened. In the embodiment
shown, the screening arrangement 1 comprises a top element 4 adapted to be positioned
at the top of a sash or a frame, a screening body 6 and a bottom element 7. At an
upper end edge, the screening body 6 is accommodated in the top element 4 and an opposed,
lower end edge is fastened to the bottom element 7. In the embodiment shown, the bottom
element 7 is adapted to act as a handle during operation of the screening arrangement
1, i.e. when moving the bottom element 7 and hence the screening body 6 between a
non-screening position and a screening position, in which the screening body 6 covers
the sash or frame aperture partly or fully. However, instead of being manually operated,
the screening arrangement may be operated by other means, e.g. by electrical operating
means.
[0024] Furthermore, the screening arrangement 1 comprises two side rails 8, 9 adapted to
be connected to respective side pieces of a sash or frame with fastening means such
as screws and by means of a bracket 490 adapted to receive a cord end and a portion
of a side rail, and to the top element 4. In the mounted position of the screening
arrangement 1, opposite ends of the bottom element 7 and opposite side edges of the
screening body 6 are guided along these side rails 8, 9. In the embodiment shown,
the screening arrangement 1 comprises a roller blind having as its screening body
6 a cloth or fabric, and of which the top element 4 includes a spring-biased roller
bar. However, other screening arrangements having other kinds of screening bodies
and other configurations of the top element are conceivable as well.
[0025] In a preferred embodiment the screening body is a roller blind and the top element
440 comprises a roller shaft which is integral with one of the end pieces 410, 420.
The integral connection between the roller shaft and the end piece is obtained by
moulding the end piece 410, 420 and the roller shaft in one piece, i.e. without subsequent
joining of any part, to form the one piece unit comprising the end piece and the roller
shaft.
[0026] From Figs. 1 and 2 it is understood that the top element 4 has a left-hand end piece
420 and a right-hand end piece 410. The terms "left-hand" and "right-hand" refer to
the orientation shown in for instance Fig. 1 and are utilized for reasons of convenience
only. Similarly, the terms "front" and "black" are utilized to denote the sides of
the screening arrangement 1, "front" being the side intended to face inwards into
the interior of a building, and "black" the outwards facing side. The terms "upper"
and "lower" refer to the orientation of the screening arrangement installed in a frame,
where "upper" refers to the top piece of the frame and "lower" refers to the bottom
piece of the frame.
[0027] In the mounted position of the screening arrangement 1, the top rail 440 is joined
to side rails 8, 9 in mitred joints by means of angular brackets 20. To that end the
top rails 440 has two mitred ends 432, 433, of which one mitred end 432 is shown in
Fig. 2 to be joined to a respective mitred end of the left-hand side rail 9.
[0028] The top rail 440 has a predetermined height and each side rail 8, 9 has a predetermined
width, and in the embodiment shown the predetermined height is substantially the same
as the predetermined width. The mitre joint is preferably a 45° mitre joint, but other
angles are conceivable.
[0029] The side edges of the screening body 6 are guided by the side rails 8, 9 in a manner
known per se, for instance by means of a number of guide beads mounted at a distance
from each other along each side edge. Hence, the side rails 8, 9 serve the purpose
of improving the light-proofing properties of the screening arrangement, as they overlap
the side edges of the screening body in the mounted position of the screening arrangement.
Eventually, depending on the type of screening body and the installation situation,
the side rails may contribute to holding the screening body in position. The bottom
edge of the screening body 6 is connected with the bottom element 7 in any suitable
manner, and the ends of the bottom element are advantageously guided by the side rails
as well.
[0030] In a preferred embodiment of the invention, the screening arrangement comprises a
parallel guidance cord system comprising two cords (not shown), one cord being adapted
to extend from the left-hand lower corner of the sash, up through or along the bottom
element 8 and further up to the top element 4. The other cord is routed in a mirror-inverted
manner. At the top element 4, each cord is connected with a respective pre-tensioning
device adapted to be connected with the top element 4. The pre-tensioning devices
entail that the cords are held at a suitable tension all the time during use, thereby
ensuring that the bottom element 7 at all times is kept substantially in parallel
with the top and bottom pieces of the sash or frame. The invention may be envisaged
with other types of cord systems wherein a portion of the cords are to be guided by
side guidance elements during installation and operation.
[0031] In Fig. 2 a part of a screening arrangement 1 is shown in the supply condition. From
each end of the top element 4 a cord is guided to an upper portion of side guidance
elements 700 and along a backside 706 (cf. Fig. 5) of the side guidance elements 700
to the bottom element 7, along or trough the bottom element to the side guidance element
700 in the respective opposite side. At the side guidance element 700 of the respective
opposite site the cords are guided adjacent to each other on the backside 706 of the
respective side guidance elements and guided to a lower portion where the cords are
guided on the backside 751 of respective cord protection sections 750 to a cord supply
fitting 10. In the embodiment of Fig. 2 the cord protection sections 750 are configured
so that the cords are released from an opening in the front surface of the side guidance
elements 700, said opening is positioned at an inner portion of the side guidance
element facing the bottom element. The opening is positioned at a distance d from
a lower edge of the side guidance element 700.
[0032] Each end of the top element 4 is provided with a coupling means 410, 420, which are
adapted to be mounted on respective brackets positioned on the upper portion side
pieces of a sash. Hence during installation of the screening arrangement 1, the coupling
means 410, 420 are mounted on the brackets and then a further bracket 490 (cf. Fig.
1) is mounted at each side of the lower portion of the sash, which further brackets
are adapted to receive a part of a side rail and a cord end of the cord system. Then
the side rails 8, 9 are mounted on the top element 4 by inserting one end of the angular
brackets 20 into a reception means on the backside of the respective side rails 8,
9. Therefore, a preferably mitred end of the side rails 8, 9 are moved in the longitudinal
direction towards a corresponding mitred end of the top rail 440 in which the angular
brackets 20 for receiving the side rails 8, 9 are mounted. While the side rails 8,
9 are moved towards the angular brackets, the respective side guidance elements 700
are positioned in a side guidance means (not shown) on the backside of the side rails
8,9, and then the side rails are mounted at the opposite end in the further reception
means. Finally, when the side rails 8, 9 have been mounted, the cord supply fittings
10 may be released and the cords may be released from their position on the backside
of the cord protection section 750 of each side guidance element 700 and mounted in
the respective further brackets at the lower portion of the sash. Since the side rails
8, 9 preferably are made of aluminium and therefore may have relatively sharp edges,
it is desirable that the cords are be protected in a simple manner in the supply condition
and during installation so that the cord system is not damaged during installation
of the side rails. When ends of the cords have been mounted in the further brackets
490, the bottom element 7 may be moved in the longitudinal defined by the length of
the side rails 8, 9 and the side guidance elements 700 are then preferably guided
in a track on the backside of the side rails 8, 9.
[0033] Fig. 3 shows a side guidance element 700 according to an embodiment of the invention
where the cord system is a parallel guidance cord system. In this and the following
Figs. only the a part of the cord system and the side guidance elements are shown
in order to explain the invention, however the orientations applied are to be understood
in relation to the remaining parts of the screening arrangements such as the side
rails and the bottom element 7. The side guidance element 700 shown in Fig. 3 is adapted
so that an inner edge 703 is to be mounted at the left-hand side of a bottom element
7 and in the following, this and further embodiments will be described with respect
to this particular left hand side guidance element 700. It is understood that a corresponding
side guidance element 700 and cords 91, 92 of the cord system is mounted and guided
in a mirror inverted manner on the right-hand side of bottom element 1. Hence, the
cords 91, 92 each have a first end 91a, 91b to be connected to the top element and
a second end 92a, 92b to be connected to a cord supply fitting 10 in the supply condition
and to a bottom bracket at a lower piece of a sash in a condition of use.
[0034] In Fig. 3 the cord system is only partly shown and the parts of the cords 91, 92
shown correspond to their position in the supply condition. A first cord 91 is received
from the top element 4 and is guided from an upper section 704 along an outer portion
760 of the side guidance element 700 to a first opening 755 in the left-hand side
outer portion 760 of the side guidance element 700. The first cord 91 is guided through
the first opening 755 and on the backside of the side guidance element in the longitudinal
direction of the bottom element. From the bottom element 7 a second cord 92 of the
cord system is received, which cord 92 is guided on the backside of the side guidance
element and through the first opening 755 to and along the outer portion 760 of the
side guidance element 700. From the outer portion 760 of the side guidance element
700 the cord is guided on the backside 751 of a cord protection section 750 to a second
opening 707 at an inner portion 770 of the side guidance element 700. Hence, the cord
92 is released from an opening in the front surface 705 next to the cord protection
section and guided to a cord supply fitting (cf. Fig. 2). In the embodiment of Fig.
3, the second opening 707 is a cut-out made in the front surface of the side guidance
element 700 so that the cut-out forms the cord protection section 752, which extends
from the front surface 705 of the side guidance element. Generally, this allows the
cord 92 to be guided on the backside 751 of the cord protection section 750 to an
opening positioned at a distance d from a lower edge of the side guidance element
707. The second opening 707 may be slightly tapered so that the cord 92 is releasably
fixed to the side guidance element 700 in the supply condition, but readily releasable
when the second cord 92 is to be mounted on a lower sash portion. As shown in Fig.
3 the side guidance elements are adapted to be mounted on an end of the bottom element
7 so that the inner edge 703 abuts the bottom element 7.
[0035] Fig. 4 shows a further developed embodiment of a side guidance element 700 according
to the invention. The view of the embodiment of Fig. 4 corresponds to the view of
Fig. 3 and hence the cords 91, 92 are guided in the same manner to from the top element
4 and to and from the bottom element 7. However, the further developed embodiment
of Fig. 4 comprises a further lower portion 702 comprising a cord guide 723 positioned
at the outer portion 760 of the side guidance element 700 and guiding, in the condition
of use, the cord 92 in the second longitudinal direction. The further lower portion
702 thus form the lower part of the side guidance element 700 and even further protects
the cord 92 during installation of the side rail 8, since at the left-hand outer portion
760 of the side guidance element 700 a rib section 740 with said cord guide 723 forms
a further protection of the cord 92 when it guided from the outer portion 760 of the
side guidance element 700 under the cord protection section 750 to the opening 707
at the right-hand side inner portion 770 of the side guidance element 700. Again the
cord 92 is guided on the backside 751 of the cord protection section 750 to an opening
positioned next to the cord protection section at a distance d from the lower edge
of the side guidance element 707. Alternatively, when a lower edge of the further
lower portion 702 is flush with a lower edge of the bottom element 7, the distance
d may be measured from the lower end edge 7a of the bottom element 7. The actual length
of the distance d depend on the height of the bottom element and the side guidance
element, but in a preferred embodiment the distance d correspond to about half or
a little less the height of the bottom element which in an exemplary embodiment measures
about 2.5 cm.
[0036] The cord protection section 750 is a tongue extending from the front side 705 of
the side guidance element 700 and the further lower portion 702 substantially extends
from the backside 706 of the side guidance element 700. Together they form a channel
in the main body of the side guidance element in which the cord 92 is guided from
the outer section 704 to the inner section 703 of the side guidance element 700. Hence
the cord 92 is guided in a plane extending between the front surface 705 and the backside
706 of the side guidance element 700. In order to ensure that the cord 92 is kept
in the supply condition during transport, the channel may for instance be tapered
so that the cord 92 is releasably fixed behind the cord protecting section, alternatively
between the cord protection section 750 and the further lower portion 702.
[0037] In order to provide a smooth surface adapted to be guided in a track of a side rail
8, the cord protecting section 750 is flush with the front side 705 of the side guidance
element 700 and the cord 92 is guided, in the supply condition, on the backside 751
of the cord protecting section 750 and released from an opening 707 in the inner portion
770 of the front side 705, which opening 707 is positioned at a distance d from the
lower edge of the bottom element 7 or an lower edge of the side guidance element 700.
This is especially advantageous in the condition of use, wherein an edge of the side
rails 8, 9 extending in the second longitudinal direction and being adapted to guide
the side guidance element 700 extend across the front side 752 the cord protection
section 750.
[0038] In the further developed embodiment of Fig. 4, which facilitates mounting and guiding
of the cords on the side guidance element 700, the side guidance element 700 comprises
a first rib section 710 extending away from the side guidance element 700 in the first
longitudinal direction, said first rib section has a free distal end 711 and a proximal
end 712 connected to the outer section 760 of the side guidance element 700, and the
side guidance element 700 comprises a second rib section 720 extending away from the
bottom element 7 in the first longitudinal direction, said second rib section has
a free distal end 721 and a proximal end 722 connected to the outer section 760 of
the side guidance element 700. In the embodiment of Fig. 4, the first rib section
710 guides a cord 91 received from the corresponding end of the top element 4, and
the second rib section 720 guides a cord 92 received from the opposite end of the
top element 4. In this way the outer section 760 is formed by the rib sections along
which the cords 91, 92 are guided.
[0039] Moreover, the side guidance element 700 comprises an intermediate rib section 730
extending away from the bottom element 7 in the first longitudinal direction between
the first and second rib sections 710, 720, said intermediate rib section has a free
distal end 721 and a proximal end 722 connected to the outer section 760 of the side
guidance element 700. The intermediate rib section 730 guides a cord 92 received from
the opposite end of the top element 4.
[0040] Fig. 5 is a perspective view from behind of the side guidance element 700 of Fig.
4. As shown the rib sections 710, 720, 730, 740 are separated by gaps 735 so that
the cords 91, 92 more easily may be guided along the outer section 760. Preferably,
each rib section 710, 720, 730, 740 is provided with a cord guide 723, which is a
recess provided on the front side or the backside of the individual rib sections 710,
720, 730, 740 so the that the cords 91, 92 are guided more secure along the side guidance
element. The first cord 91 received from the top element is guided along the first
rib section 710 and through a recess 724 formed by a portion of the first rib section
710 and the intermediate rib section 730 on the backside 706 of the side guidance
element. In the supply condition of Figs. 4 and 5, the second cord having one end
92a connected to the cord supply fitting (cf. Fig. 2) is guided below the cord protecting
section 750 to the backside of second rib section 720 along the front side of the
intermediate rib section 730 to the recess 724, where the cord 92 is guided adjacent
to the first cord 91. Hence the ends 91b, 92b of the cords are guided along or in
the bottom element 7.
[0041] The invention should not be regarded as being limited to the described embodiments.
