Field of the invention
[0001] The invention relates to a slat control system. The invention further relates to
a slat frame with the slat control system and to a structure with the slat frame.
Background
[0002] Slats are typically used for protecting an area against weather and wind, for instance
for protecting a terrace against the sun. The slats are attached at each outer end
to a first profile of a slat guide. A second profile of the slat guide is then mounted
in a frame and allows a relative movement of the first and the second profile in order
to tilt the slats synchronously.
[0003] A drawback of these slat guides is that they are complex in respect of installation,
are aesthetically less attractive, and are difficult to repair when damaged.
Summary of the invention
[0004] Embodiments of the invention have the object of providing a slat control system which
can be installed in simple manner, can be easily operated and can be repaired in simple
manner.
[0005] According to a first aspect, the invention provides for this purpose a slat control
system which is configured to control the tilting of two or more slats which are mounted
tiltably in an opening of a slat frame. The slat control system comprises at least
two coupling pieces and an operating means, wherein each of the at least two coupling
pieces is couplable at a first outer end to a lateral side of one of the two or more
slats and is couplable at a second outer end to the operating means. The operating
means extends along the two or more slats in this way. The operating means is configured
to tilt the two or more slats substantially synchronously between a first tilting
position and a second tilting position when the operating means moves, wherein in
the first tilting position the slats close the opening of the slat frame and in the
second tilting position the slats leave the opening of the slat frame at least partially
open.
[0006] This has multiple advantages. A first advantage of the slat control system is the
accessibility thereof. Because the operating means extends along the lateral side
of the two or more slats and couples them to each other via the at least two coupling
pieces, the tilting position of the slats is controllable in operationally very simple
manner. This is because the movement of the operating means results in tilting of
the slats in the slat frame. The operating means is moreover easily reachable. A second
advantage hereof is based on the insight that, in the case of a slat guide as known
in the prior art, the person must use his or her hand on the slats themselves in order
to tilt them. This entails the risk of the hand or fingers becoming trapped between
slats due to a gust of wind or inattentiveness, resulting in physical injury. Use
of the operating means thus also avoids physical injuries. A further advantage is
based on the insight that, because the operating means couples the two or more slats
to each other via the coupling pieces, the slats are easier to install. This is because
these slats can be mounted rotatably in the frame in simple manner and individually,
for instance with a bearing in the frame which receives a shaft of the slat. Placing
of the operating means can furthermore be carried out independently of mounting of
the slats on the slat frame. On one hand, this simplifies assembly of the slat frame,
and on the other it also simplifies repairs thereto. Each component of the slat control
system and the slats themselves can thus be repaired or replaced separately in simple
manner.
[0007] Each coupling piece preferably comprises a first coupling piece part and a second
coupling piece part, wherein the first and the second coupling piece part are connectable
for relative rotation about a shaft and are each provided with a mounting means which
is configured to mount the first coupling piece part and the second coupling piece
part on respectively the operating means and one of the two or more slats. In this
way the operation of the locking system is improved further. More specifically, this
allows the changing orientation of the operating means relative to the two or more
slats to be accommodated with the first and the second coupling piece part when the
slats tilt. In other words, the coupling piece functions as a hinge between the two
or more slats and the operating means. This further has the advantage that both the
operating means and the coupling pieces are adaptable to almost any situation of the
slat frame in very simple and modular manner. The coupling pieces can for instance
be supplied in bulk, and the operating means can also be supplied in bulk in generic
manner. A number of coupling pieces corresponding with the number of slats to be coupled
can then be arranged in the slats. The operating means can then be cut to size and
be connected to the coupling pieces, more specifically the second coupling piece part.
Because the first and second coupling piece part are mutually connectable and rotatable,
the slat control system therefore allows highly modular operation, the slat frame
can thus for instance comprise a plurality of sections, wherein each section of slats
is individually controllable by a control system.
[0008] The mounting means is preferably provided with one or more protrusions which extend
from the mounting means in a direction radially of an outer surface of the mounting
means. More preferably, each protrusion comprises an insertion surface and a stop
surface, wherein the stop surface lies at right angles to the outer surface of the
mounting means and the insertion surface has an oblique angle with the stop surface
and the outer surface, wherein the insertion surface is directed toward the first
outer end. This allows the coupling piece to be used in combination with a plurality
of different types of material. More specifically, the protrusions anchor the mounting
means, and consequently the first and the second coupling piece, in an opening in
both the slats and the operating means in simple manner. More preferably provided
are a plurality of protrusions, which are arranged distributed over the outer surface
of the mounting means. This further improves the mounting of the coupling piece part
in one of the operating means and the slat. According to a further preferred embodiment,
wherein the operating means is a hollow profile with two or more mounting openings
which are provided for mounting a mounting means in, the stop surface also engages
a surface of the hollow profile when it is arranged through an opening in the hollow
profile. This allows the first coupling piece part to be mounted on the operating
means in rapid and simple manner. The two or more mounting openings are more preferably
placed at a regular pitch distance from each other. This simplifies placing of the
operating means further and increases the modularity of the control system further.
[0009] The first coupling piece part is preferably provided at a proximal outer end with
a shaft and the second coupling piece part is provided at a distal outer end with
a shaft engaging means which is configured to engage the shaft of the first coupling
piece part. Because the shaft is provided at the proximal outer end of the first coupling
piece part and the shaft engaging means is provided at the distal outer end, the first
and second coupling piece parts are mutually connectable in simple manner.
[0010] The first coupling piece part is preferably provided at a proximal outer end with
a recess comprising two opposite inner walls, wherein the shaft has two shaft segments,
each extending partially into the recess from a respective inner wall, and the shaft
engaging means is provided to extend between the two shaft segments and comprises
on either side two cavities which are each configured to receive one of the two shaft
segments. In this way the shaft segments are directed inward. The space between the
two shaft segments allows the shaft engaging means to be aligned and arranged therebetween
in simple manner. The cavities then allow the two shaft segments of the first coupling
piece part to be coupled to the second coupling piece part in efficient manner.
[0011] More preferably, each shaft segment comprises an outer surface having an at least
partially circular cross-section, wherein the two cavities comprise an inner wall
which is shape-compatible with the outer surface of the shaft segment. In this way
the shaft segments and cavities facilitate a rotating movement of the first coupling
piece part relative to the second coupling piece part, and vice versa. The outer surface
of each shaft segment more preferably comprises at least one cut-out portion which
forms a stop surface extending along a longitudinal axis of the shaft segment, wherein
the inner wall has a flat portion compatible with the stop surface. This allows the
first coupling piece part and the second coupling piece part to be temporarily locked
in the position in which the stop surface coincides with the flat portion.
[0012] Each shaft segment preferably comprises at a distal outer end a first surface which
is oriented transversely of a longitudinal direction of the shaft segment and comprises
a second surface which lies at an angle to the first surface so that the second surface
is directed outward relative to the recess. The first surface, which is oriented transversely,
has the advantage that a clearance between the shaft segment and the cavities is substantially
constant. This therefore limits the freedom of movement of the second coupling piece
part in the longitudinal direction of the shaft segment. The second surface, which
lies at an angle, allows for the second coupling piece part to be guided to a position
in which the coupling piece part is connected to the two shaft segments. The resistance
while arranging the second coupling piece part on the first coupling piece part is
moreover limited so that the shaft segments are less inclined to break off, or tend
not to do so at all.
[0013] The two cavities are preferably bounded at least partially by a rib, wherein the
rib is configured to extend over an edge of the inner walls. The rib functions on
one hand as a stop, so that the second coupling piece part is prevented from being
arranged too far into the recess of the first coupling piece part. On the other hand,
the rib also functions as rotation limiting means.
[0014] The slat control system preferably further comprises a damping means which is mountable
on the slat frame and is connectable to one of the two or more slats, wherein the
damping means is configured to damp a tilting movement of the slat. The damping means
is more preferably connected to the slat via a gear transmission.
[0015] According to a second aspect, the invention provides a slat frame comprising a plurality
of slats which are mounted tiltably in an opening of a slat frame, wherein two or
more slats are connected for mutual control via a slat control system as described
above.
[0016] According to a third aspect, the invention provides a structure, preferably a terrace
covering, comprising a slat frame, preferably a slidable slat frame with said slat
control system.
[0017] The advantages stated in respect of the slat control system apply
mutatis mutandis for the slat frame and a structure comprising the slat frame.

references, unless clearly indicated otherwise by the context.
[0022] The terms "comprising", "comprises" and "composed of" as used here are synonymous

[0023] The terms first, second, third and so on are further used in the description and

than described or illustrated here.
[0024] Reference in this specification to "one embodiment", "an embodiment", "some aspects",
"an aspect" or "one aspect" means that a determined feature, structure or characteristic
described with reference to the embodiment or aspect is included in at least one embodiment
of the present invention. The manifestations of the sentences "in one embodiment",
"in an embodiment", "some aspects", "an aspect" or "one aspect" in different places
in this specification thus do not necessarily all refer to the same embodiment or
aspects. As will be apparent to a skilled person in this field, the specific features,

or more embodiments or aspects. Although some embodiments or aspects described here

combinations of features of different embodiments or aspects are further intended
to fall within the context of the invention and to form different embodiments or aspects,
as would be apparent to the skilled person. In the appended claims all features of
the claimed embodiments or aspects can for instance be used in any combination.
[0025] The same or similar elements are designated in the drawing with the same reference
numeral.
[0026] Figure 1 shows a slat frame 200 in which a plurality of slats 210 are arranged. The
slat frame 200 can be used as a wall in an outdoor structure, for instance for protecting
a terrace against wind and sun. The slat frame 200 can also be used as a ceiling for
the outdoor structure. Slat frame 200 can be arranged both statically and displaceably
in the outdoor structure. Slat frame 200 can thus be suspended from a guide in order
to displace slat frame 200 along the guide. In order to compensate for a height difference
between two outer ends of the outdoor structure a height control means as shown in
figure 6 can be provided.
[0027] Slat frame 200 comprises a plurality of slats 210. A slat 210 is typically strip-like
with a substantially elongate primary dimension, as seen in the longitudinal direction,
and a secondary dimension which is significantly smaller than the primary dimension.
The slats 210 can be manufactured from various materials such as aluminium, wood or
plastic, which are arranged tiltably on frame 200.
[0028] Slats 210 are arranged tiltably in an opening O of slat frame 200. In the context
of this application the tilting of slats is defined as rotating the slat 200 around
a longitudinal axis of the slat. More specifically, slats 200 are mounted tiltably
in an opening O defined by the slat frame 200, so that they are tiltable between a
first tilting position and a second tilting position. In the first tilting position
slats 210 close the opening O of slat frame 200. In this position mutually adjacent
slats 210 connect closely to each other by lying with their mutually adjacent lateral
sides against or substantially against each other. In other words, an opening between
adjacent slats is minimized. This substantially prevents incidence of light, so that
the area behind slat frame 200 is shaded. It will be apparent that, in this position,
wind is also partially blocked. In the second tilting position slats 210 leave the
opening of slat frame 200 at least partially open. This means that the slats still
lie in the field of vision of the opening O, but are positioned such that the opening
between adjacent slats 210 is considerably greater than in the first tilting position.
[0029] In order to control the tilting of slats 210 a slat control system 100 according
to a preferred embodiment is provided. As shown in figure 1, it is not essential for
all slats 210 in slat frame 200 to be controlled with the same slat control system
100. A plurality of zones, three zones O1, O2, O3 are shown in the figure, can thus
be realized in slat frame 200 using the slat control system 100. Each of the slats
210 in each zone can be controlled by a respective slat control system 100. It is
further also possible to adapt a slat zone, for instance zone O3, into a full zone,
wherein the zone is covered fully by a plate. Alternatively or in combination, a zone
can also comprise no slats. The proposed slat control system 100 allows slat frames
to be constructed and controlled in highly creative, aesthetically attractive and
modular manner.
[0030] Figure 2 shows an exploded view of a portion of the slat frame shown in figure 1.
Figure 2 shows in more detail that the slat control system 100 comprises at least
two coupling pieces 110 and an operating means 150. Figure 2 shows six coupling pieces
110. It will however be apparent that only some of the coupling pieces comprised in
figure 1 are shown, and that more than or less than six coupling pieces can also be
provided.
[0031] Each of the at least two coupling pieces 110 is couplable at the position of a first
outer end to a lateral side of a slat 210. The lateral side is a side of the slat
210 which extends in the longitudinal direction of the slat and is situated at a distance
from an axis of the slat. The lateral side is distinguishable from the end surface
of the slat. This end surface is particularly connected rotatably to the slat frame
(not shown). Each of the at least two coupling pieces 110 is further couplable at
a second outer end to the operating means 150. Operating means 150 extends in this
way along the two or more slats 210. In the figure the operating means 150 extends
along six slats 210. A first advantage van het slat control system 100 is the accessibility
thereof. Because operating means 150 extends along the lateral side of the two or
more slats 210 and couples them to each other via the at least two coupling pieces
110, the tilting position of the slats is controllable in operationally very simple
manner. This is because the movement of the operating means results in tilting of
the slats in the slat frame, as will be further elucidated below. Operating means
150 moreover also lies at a distance from the slats 210. This improves the accessibility
and reachability of operating means 150 and moreover reduces the risks of fingers
or hands becoming jammed between the slats. Operating means 150 is configured to tilt
the two or more slats 210 substantially synchronously between the first tilting position
and the second tilting position when operating means 150 moves. Synchronous tilting
is understood to mean that the different slats 210 which are coupled via coupling
pieces 110 to operating means 150 take up substantially the same orientation relative
to the slat frame at the same time. According to the embodiment shown in figure 2,
slats 210 have a lying orientation, whereby a person can see substantially through
the openings between slats 210. In this orientation the lateral side of slat 210 is
directed substantially transversely of the plane formed by the opening of slat frame
200. When operating means 150 is operated, slats 210 can have an angle to the plane
of slat frame 200, the mutual connections between the slats and the operating means
ensuring that all slats connected to the operating means 150 will have a similar angle.
[0032] It will further be apparent on the basis of figure 2 that the operating means 150
couples the two or more slats 210 to each other via the coupling pieces. Slats 210
are thus easier to install. These slats 210 can be mounted rotatably in slat frame
200 in simple manner and individually, for instance with a bearing in the frame which
receives a shaft of the slat. The placing of operating means 150 can furthermore be
carried out independently of the slats 210 being mounted on the slat frame. On one
hand, this simplifies assembly of the slat frame, and on the other it also simplifies
repairs thereto. Each component of the slat control system 100 and the slats themselves
can thus be repaired or replaced separately in simple manner.
[0033] Figure 3 shows a perspective view of a portion of the slat control system 100 shown
in figure 2, in which operating means 150, coupling piece 110 and slat 210 are shown
in more detail. Figure 3 more specifically shows that each coupling piece 110 preferably
comprises a first coupling piece part 120 and a second coupling piece part 130, wherein
the first coupling piece part 120 and the second coupling piece part 130 are connectable
for relative rotation about an axis. Each coupling piece part is furthermore provided
with a mounting means 121, 131 which is configured to mount respectively the first
coupling piece part 120 and the second coupling piece part 130 on respectively the
operating means 150 and the slat 210. This further improves the operation of the slat
control system 100. More specifically, this allows the changing orientation of the
operating means relative to the two or more slats to be accommodated with the first
and the second coupling piece part when the slats tilt. In other words, coupling piece
110 functions as a hinge between the two or more slats and the operating means. This
further has the advantage that both operating means 150 and coupling pieces 110 are
adaptable to almost any situation of the slat frame in very simple and modular manner.
The coupling pieces 110 can for instance be supplied in bulk, and the operating means
can also be supplied in bulk in generic manner. A number of coupling pieces 110 corresponding
to the number of slats to be coupled can then be arranged in the slats. In the embodiment
of figure 3 this would thus be six slats that must be coupled correspondingly to a
coupling piece. In this situation, six coupling pieces would thus have to be provided.
Depending on the number of slats and the distance therebetween, operating means 150
can be cut to size and then be connected to the coupling pieces, more specifically
the second coupling piece part 130. Because the first and second coupling piece parts
120, 130 are mutually connectable and rotatable, the slat control system 100 therefore
allows highly modular operation, the slat frame can thus for instance comprise a plurality
of sections, wherein each section of slats is individually controllable by a slat
control system, as was elucidated with reference to figure 1.
[0034] Figure 4 shows a perspective exploded view of a coupling piece 110 comprising a first
and a second coupling piece part 120, 130 according to a preferred embodiment.
[0035] As described above, coupling piece 110 preferably comprises a first coupling piece
part 120 and a second coupling piece part 130 which are connected for relative rotation
about an axis. Each coupling piece part 120, 130 is moreover provided with a mounting
means 121, 131 which is configured to mount respectively the first coupling piece
part 120 and the second coupling piece part 130 on respectively operating means 150
and slat 210.
[0036] Mounting means 121, 131 can be provided with one or more protrusions 121a, 121b,
121c, 121d, 121e, 131a, 131b, 131c which extend from mounting means 121, 131 in a
direction radially of an outer surface of mounting means 121, 131. The protrusions
preferably have an insertion surface and a stop surface, wherein the stop surface
lies at right angles to the outer surface of the mounting means and the insertion
surface lies at an oblique angle to the stop surface and the outer surface, wherein
the insertion surface is directed toward the outer end of the respective coupling
piece part. In this way the mounting means can be arranged in a recess arranged in
the operating means or slat in relatively simple manner. The combination of stop surface
and insertion surface form a barb whereby the mounting means 121, 131 is also mountable
in said recess in simple and robust manner. More preferably provided are a plurality
of protrusions, which are arranged distributed over the outer surface of the mounting
means. The distribution can be seen both along the periphery of the mounting means
and in the length direction thereof, or a combination. The mounting means 121 of the
first coupling piece part 120 is thus shown with two (visible rows of) protrusions,
the first row of which is designated with reference numerals 121a, 121b, 121c, 121d,
121e. This row is formed by a plurality of protrusions 121a, 121b, 121c, 121d, 121e,
which lie adjacently of each other as seen in a length direction of the mounting means
121. Further arranged at a distance from the first row is a second row (and third
and fourth row, although not visible in the figure). This further improves the mounting
of the coupling piece part in one of the mounting means 150 and the slat 210. The
mounting means 121 of the first coupling piece part 120 need not necessarily be identical
to the mounting means 131 of the second coupling piece part 130, as shown in figure
4. The mounting means 131 of the second coupling piece part 130 thus comprises four
protrusions (three of which are shown) 131a, 131b, 131c, which are distributed along
the periphery. Such protrusions are advantageous in a further preferred embodiment
wherein the operating means 150 is a hollow profile with two or more mounting openings
(not shown) which are provided for mounting a mounting means 131 in, and the stop
surface also engages a surface of the hollow profile when it is arranged through an
opening in the hollow profile. This allows the first coupling piece part to be mounted
on the operating means in rapid and simple manner. The two or more mounting openings
are preferably placed at a regular pitch distance from each other, the openings for
instance being placed at a mutual distance corresponding to the distance between the
slats. This simplifies placing of the operating means further and increases the modularity
of the control system further. The operating means can moreover be cut to size depending
on the zone O1, O2 or O3 to be controlled.
[0037] Figure 4 further shows that the first coupling piece part 120 can be provided at
a proximal outer end P1 with a shaft 122a, 122b and the second coupling piece part
130 can be provided at a distal outer end D2 with a shaft engaging means 132 which
is configured to engage the shaft of the first coupling piece part. Because the shaft
122a, 122b is provided at the proximal outer end P1 of the first coupling piece part
120 and the shaft engaging means 132 is provided at the distal outer end D1, the first
and second coupling piece parts 120, 130 are mutually connectable in simple manner.
[0038] The first coupling piece part 120 is more preferably provided at a proximal outer
end P1, provided with a recess which comprises two opposite inner walls 123. These
inner walls 123 can lie adjacently of the drilled hole formed in the slat, see figure
3. The shaft further has two shaft segments 122a, 122b, each extending partially into
the recess from a respective inner wall. In this way a space is created between the
outer ends of the two shaft segments 122a, 122b. The shaft engaging means 132 can
further be provided to extend between the two shaft segments 122a, 122b, i.e. in the
space, and the shaft engaging means 132 further comprises on either side two cavities
133 (the second cavity is not visible due to the perspective view) which are each
configured to receive one of the two shaft segments 122a, 122b. The space between
the two shaft segments 122a, 122b allows the shaft engaging means 132 to be aligned
and arranged therebetween in simple manner. The cavities 133 then allow the two shaft
segments of the first coupling piece part 120 to be coupled movably to the second
coupling piece part 130 in efficient manner. The cavities 133 and the shaft segments
122a, 122b co-act correspondingly and in this way form components of a snap-fit connection.
[0039] In order to facilitate a rotating movement of the first coupling piece part 120 relative
to the second coupling piece part 130 and vice versa, each shaft segment 122a, 122b
preferably comprises an outer surface having an at least partially circular cross-section.
The two cavities 133 moreover have an inner wall which is shape-compatible with the
outer surface of the shaft segment 122a, 122b. The outer surface of each shaft segment
122a, 122b more preferably comprises at least one cut-out portion which forms a stop
surface 124 extending along a longitudinal axis of the shaft segment. The stop surface
124 is directed outward in a direction of the second coupling piece part. In other
words, the stop surface 124 lies substantially vertically and is oriented in a direction
away from the distal outer end D1 of the first coupling piece part 120. In combination
herewith, the inner wall of the shaft engaging means has a flat portion 136 compatible
with the stop surface. This allows the first coupling piece part and the second coupling
piece part to be temporarily locked in the position in which the stop surface coincides
with the flat portion.
[0040] Figure 4 further shows that each shaft segment 122a, 122b can comprise at a distal
outer end thereof a first surface 125 which is oriented transversely of a longitudinal
direction of the shaft segment 122a and comprises a second surface 126 which lies
at an angle to the first surface so that the second surface is directed outward relative
to the recess. The first surface 125, which is oriented transversely, has the advantage
that a clearance between the shaft segment and the cavities is substantially constant.
This therefore limits the freedom of movement of the second coupling piece part 120
in the longitudinal direction of the shaft segment 122a. The second surface 126, which
lies at an angle, allows for the second coupling piece part to be guided to a position
in which the second coupling piece part 130 is connected to the two shaft segments.
The resistance while arranging the second coupling piece part on the first coupling
piece part is moreover limited so that the shaft segments are less inclined to break
off, or tend not to do so at all. This resistance can be altered by adjusting the
angle between the first surface 125 and the second surface 126.
[0041] The two cavities 133 are preferably bounded at least partially by a rib 134, wherein
the rib is configured to extend over an edge 127 of the inner walls. The rib 134 functions
on one hand as a stop so that the second coupling piece part 130 is prevented from
being arranged too far into the recess of the first coupling piece part 120. On the
other hand, the rib also functions as rotation limiting means. The rotation of the
first coupling piece part 120 relative to the second coupling piece part 130 can be
partially limited by adjusting the arc length through which the rib 134 extends. By
increasing the arc length of rib 134 the edge of the wall of the first coupling piece
part 120 will hit the rib sooner and will prevent a further rotation from taking place
in this same direction.
[0042] Figure 5 shows a damping means for use with the slat control system. The damping
means 140 is mountable on the slat frame 200 and is connectable to one of the two
or more slats 210. Damping means 140 is configured to damp a tilting movement of slat
210. Because the two or more slats are connected by the operating means, these slats
are therefore also indirectly connected to the damping means 140. The damping means
can be connected to any of the slats connected to the operating means and need only
be fixed to the frame. The figure shows that the damping means is fixed in a profile
of the frame using a bracket 170 which can be clamped between two legs of the profile.
Figure 5 further shows that the damping means is preferably connected via a gear transmission
160 to the slat. This allows the damping force to be controlled depending on the intended
purpose.
[0043] Figure 6 shows a height control means 180 according to a preferred embodiment. The
height control means 180 is configured to guide the slat frame along a T-shaped guide
(not shown). The advantage thereof is based on the insight that outdoor structures,
such as a terrace, typically have an oblique ground surface in order to realize drainage.
The T-shaped guide thus lies higher on one side than on the other. In other words,
the one outer end of the T-guide lies higher than the other outer end. In order to
compensate for the difference in height caused thereby, the slat control system can
further comprise a height control means 180 with a slot 181 which is intended to surround
the upward directed leg of the T-shaped guide. The height control means 180 further
comprises a mounting means 183 which is configured to mount the height control means
on the slat frame. The mounting means is mounted on an underside of the slat frame.
The height control means is arranged for rotation relative to mounting means 183 so
that, when the slat frame moves along the T-guide, the height control means 180 is
held on the T-guide gravitationally and the slot limits the lateral movement of the
slat frame relative to the guide. In order to hold the height control means on the
T-guide the height control means can be disposed elastically. For this purpose a resilient
element 182 is provided, which drives the height control means 180 toward the T-guide.
[0044] In this way the height control means 180 is held on the T-guide in a robust manner,
irrespective of the position of the slat frame.
[0045] Figure 7 shows a perspective view of a locking system 300 according to a preferred
embodiment. The locking system 300 is configured to be mounted on a structure, for
instance a terrace covering, in a profile of a sliding frame. The sliding frame can
be a frame as shown in figure 1. The locking system 300 is configured to lock the
sliding frame relative to the structure. For this purpose the locking system 300 is
provided with a locking means 310 which is coupled displaceably to a base 320. The
base 320 is configured to be mounted in the profile, see figures 8A, 8B and 9.
[0046] The locking means 310, illustrated as a pin, is displaceable between a releasing
position and a locking position. The locking means 310 is provided to lock the location
of the sliding frame relative to the structure in the locking position.
[0047] Figure 7 further shows that locking system 300 can be connectable to an actuator
330. The actuator 330 is coupled to the locking means 310. Actuator 330 is movable
between a first and a second position such that a movement from the first to the second
position displaces locking means 310 from the releasing position to the locking position
and vice versa. Although not shown, actuator 330 extends at least partially through
the profile. For this purpose the profile can be provided with an opening so that
the actuator is freely accessible from the outside. Because the position of the actuator
is correlated to the position of the locking means, a user can thus operate the locking
system in very simple manner via the actuator. Actuator 330 further comprises a connecting
means 331 which extends between the actuator 330 and the locking means 310. Further
features of the connecting means will be elucidated with reference to figures 8A and
8B.
[0048] Figure 8A shows a cross-section of the locking system in a locking position. Figure
8B shows a cross-section of the locking system in a releasing position. For the sake
of further clarity, figure 9 shows a perspective view of the locking system in a releasing
position as according to figure 8B.
[0049] Figures 8A, 8B and 9 thus show a transverse beam 1000 of a structure, for instance
a transverse beam of a terrace covering. Provided on an underside of transverse beam
1000 is a rail 1100. In this embodiment the sliding frame is arranged slidably in
the rail 1100. This allows the sliding frame to slide along the length of the transverse
beam, this length typically corresponding with the length or at least a part of the
length of the terrace covering.
[0050] More specifically, figures 8A and 8B show that locking system 300 further comprises
a lock 350 which is fixed to the structure 1000 and comprises at least one locking
provision 351. The at least one locking provision 351 is visible in figure 9. Figure
8A shows that the locking provision 351 is configured to receive locking means 310
when the locking means 310 is in the locking position. The lock 350 limits the freedom
of movement of locking means 310 in a direction of movement of rail 1100. Because
locking means 310 is connected to the sliding frame, the locking means 310 in the
locking position thus also limits the freedom of movement of the sliding frame in
the direction of movement of rail 1100. Figure 8 further shows that locking system
300 is arranged in the profile 200a, 200b in compact manner, i.e. on an inner side
of the profile. In this way only an outer side of the profiles is visible from the
outside, and a neatly finished and aesthetically modern appearance is realized. Locking
system 300 is further robust in that the base 320 is enclosed almost wholly by the
profile. In order to connect locking means 310 to the locking provision 351 the locking
means 310 extends through profile 200b. Locking means 310 can extend through the profile
both in the locking position and in the releasing position. It is thus only essential
for the locking means 310 to be surrounded by the locking provision 351 of lock 350
in the locking position.
[0051] Figures 8A and 8B show that the actuator comprises a connecting means 331 which extends
between the actuator and the locking means 310. This allows the actuator to be placed
at a distance from the locking means, for instance in an upright profile of the sliding
frame. The advantage hereof is based on the insight that the locking means 310 and
the lock are preferably provided at the position of an upper or lower segment of the
sliding frame. Connecting means 331 for instance allows operation of locking means
310 halfway along the sliding frame, where the actuator may be provided. Connecting
means 331 is more preferably strip-like, as shown in figure 7. As already described,
a strip-like connecting means is advantageous because a strip, as seen in a length
direction, is considerably longer than it is in the width direction thereof. The strip
has a thickness direction perpendicularly of the width direction. The strip-like connecting
means 331 is relatively stiff as seen in the width direction, but flexible in the
thickness direction. This allows a span between actuator and locking means to be accommodated
in relatively simple manner with the strip-like connecting means 331. This bridging
is shown visibly in figures 8A and 8B. The bridging is caused in that the sliding
frame is typically suspended displaceably in the rail 1100, which has a central guide
opening. In this configuration locking means 310 must thus also move through the central
guide opening of rail 1100, and is therefore situated at a bridgeable distance from
a side wall of the sliding frame on which actuator 330 can be provided in easily reachable
manner.
[0052] The strip-like connecting means 331 further has the advantage that the connecting
means can be partially received at the edges thereof in a slot 201a which can be formed
in the profile 200a. The slot 201a limits the freedom of movement of connecting means
331 in a width direction thereof so that only a movement in the longitudinal direction
of the slot and consequently connecting means 331 is possible. In order to realize
the connection between the slot and the connecting means a portion of the connecting
means can have a first part and a second part with different widths. At the position
of the first part the width of the connecting means 331 is smaller than the distance
between two opposite slots. This means that the connecting means 331 fits between
the slots but does not slide therein. At the position of the second part the width
of the connecting portion is such that the edges of the connecting means slide in
the slots. In this way a movement is thus allowed only in the longitudinal direction
of the slots. In the figure the longitudinal direction is the same as an upward direction
of the sliding frame.
[0053] Figures 8A and 8B show that, according to a preferred embodiment, the actuator is
connected via a force transmission structure to the locking means 310. The force transmission
structure has a lifting arm base 311 with a proximal outer end 311p and a distal outer
end 311d. At the proximal outer end 311p the lifting arm base 311 is connected via
a pivoting connection to actuator 331. At the distal outer end the lifting arm base
311 has a connecting piece 312 which is connected pivotally to the base 320. The lifting
arm base 311 is thus connected on one side to the actuator and on the other side to
the base 320. The lifting arm base 311 can also be directly pivotally connected to
the base 320. Figures 8A and 8B further show that the locking means 310 is connected
pivotally to the lifting arm base 311 between the proximal outer end 311p and the
distal outer end 311d. Because the lifting arm base is disposed pivotally in the base
and the locking means 310 is connected pivotally to the lifting arm base between the
proximal and distal outer end thereof, a rotation of the lifting arm base results
in an at least partial upward or downward movement of the locking means 310. The force
transmission structure has the advantage that the locking means is less inclined to
move out of lock 350, for instance due to wind rattling the sliding frame. The force
transmission structure further has the advantage that an equal or greater force on
the locking means 310 is realized with less force.
[0054] The connecting piece 312 also comprises a distal outer end 312d and a proximal outer
end 312p. It is preferred for the connecting piece to be connected pivotally to the
base 320 at the proximal outer end 312p. In order to control a distance over which
locking means 310 is displaceable the distance between pivoting connection 312p and
lifting arm base 311 can be adjusted. A greater distance results in a greater displacement
of locking means 310.
[0055] Base 320 can further comprise a guide which is configured to guide locking means
310 in substantially vertical direction. The lifting arm base can further also be
mounted rotatably in a guide in base 320. This guide can be directed substantially
vertically and allows the lifting arm base to be movable upward and downward in the
guide. Coupling the lifting arm base rotatably to the guide further provides a similar
force transmission structure as described above, with the additional advantage that
the upward and downward displacement of the locking means is also guided by the lifting
arm base in the guide. The connecting piece 312 can further be connected via a sliding
piece 313 which lies opposite pivoting connection 312p and is connected to the locking
means. Sliding piece 313 is connected slidably to locking means 310 and in this way
further improves the robustness of the locking system. More specifically, the degrees
of freedom of the connecting piece and the locking means are reduced further.
[0056] Figure 9 shows a perspective view of a front and upper segment of a sliding frame.
The figure more specifically shows that a portion of transverse beam 1000 has been
cut away in order to show the lock 350. Figure 9 further shows that the sliding frame
can be provided with a slat control system as elucidated with reference to figures
1-5.
[0057] According to the illustrated preferred embodiment, lock 350 comprises a plurality
of locking provisions 351 which are arranged distributed relative to the structure.
This allows the sliding frame to be locked at multiple locations along the rail 1100.
[0058] Figure 9 further shows that locking means 310 is preferably arranged at a front segment
of the sliding frame, preferably at the position of a corner of the sliding frame.
The advantage hereof is based on the insight that the profiles are preferably connected
to each other in mitred manner. This has an aesthetically attractive appearance and
can moreover be manufactured in relatively simple manner. At the position of the corner
of the sliding frame with profiles coupled in mitred manner, only profile 200a being
shown in the figure, the inner space of each of the profiles coincides. This space
can be utilized optimally by providing the locking means and the base at the position
of the corner. This further has the advantage that the actuator and the connecting
means are connectable directly to the base and the locking means, wherein the base
has an outer dimension adapted to fit in an opening of the profile.
[0059] The skilled person will appreciate on the basis of the above description that the
invention can be embodied in different ways and on the basis of different principles.
The invention is not limited here to the above described embodiments. The above described
embodiments and the figures are purely illustrative and serve only to increase understanding
of the invention. The invention is not therefore limited to the embodiments described
herein, but is defined in the claims.
[0060] The above described aspects and features of the slat control system can further be
combined with a locking system configured to be mounted in a profile of a sliding
frame on a structure, for instance a terrace covering, and to lock the sliding frame
relative to the structure. The locking system comprises a locking means which is coupled
displaceably to a base configured to be mounted in the profile, wherein the locking
means is displaceable between a releasing position and a locking position wherein
the locking means protrudes through the profile. The locking system further comprises
a lock which is configured to be fixed to the structure and which comprises at least
one locking provision configured to receive the locking means when the locking means
is in the locking position. Because the locking system is arranged in the profile
in compact manner, i.e. on an inner side of the profile, practically only the profiles
are visible from the outside. In this way a neatly finished and aesthetically modern
appearance is realized. The locking system is further robust in that the base is enclosed
almost wholly by the profile.
[0061] The locking system preferably comprises an actuator which extends at least partially
through the profile, wherein the actuator is coupled to the locking means and is movable
between a first and a second position such that a movement from the first to the second
position displaces the locking means from the releasing position to the locking position
and vice versa. Because the actuator extends at least partially through the profile,
the actuator is freely accessible from the outside. Because the position of the actuator
is correlated to the position of the locking means, a user can thus operate the locking
system in very simple manner via the actuator.
[0062] The actuator preferably comprises a connecting means which extends between the actuator
and the locking means. This allows the actuator to be placed at a distance from the
locking means. The advantage hereof is based on the insight that the locking means
and the lock are preferably provided at the position of an upper or lower segment
of the sliding frame. The connecting means for instance allows the locking means to
be operated halfway along the sliding frame, where the actuator may be provided. The
connecting means is more preferably strip-like. A strip-like connecting means is advantageous
because a strip is considerably longer as seen in a length direction than it is in
the width direction thereof. The strip has a thickness direction perpendicularly of
the width direction. The strip-like connecting means is relatively stiff as seen in
the width direction, but flexible in the thickness direction. This allows a span between
actuator and locking means to be accommodated in relatively simple manner with the
strip-like connecting means. The strip-like connecting means further has the advantage
that the connecting means can be partially received at the edges thereof in a slot
which can be formed in the profile. The slot limits the freedom of movement of the
connecting means in a width direction so that only a movement in the longitudinal
direction of the connecting means is possible. A length of the connecting means is
more preferably controllable.
[0063] The actuator is preferably connected via a force transmission structure to the locking
means, wherein the force transmission structure has a lifting arm base with a proximal
outer end and a distal outer end, wherein the lifting arm base is connected via a
pivoting connection to the actuator at the proximal outer end, and wherein the lifting
arm base comprises at the distal outer end a connecting piece which is connected pivotally
to the base, wherein the locking means is connected pivotally to the lifting arm base
between the proximal outer end and the distal outer end.
[0064] The base preferably comprises a guide which is configured to guide the locking means
in substantially vertical direction, and wherein the connecting piece is connected
to the locking means via a sliding piece lying opposite the pivoting connection. In
this way the robustness of the locking system is improved further. More specifically,
the degrees of freedom of the connecting piece and the locking means are reduced further.
[0065] The locking means is preferably arranged at a front segment of the sliding frame,
preferably at the position of a corner of the sliding frame. The advantage hereof
is based on the insight that the profiles are preferably connected to each other in
mitred manner. At the position of the corner of the sliding frame with profiles coupled
in mitred manner the inner space of each of the profiles coincides. This space can
be utilized optimally by providing the locking means and the base at the position
of the corner. This further has the advantage that the actuator and the connecting
means are connectable directly to the base and the locking means.
[0066] The lock preferably comprises a plurality of locking provisions which are arranged
distributed relative to the structure. This allows the sliding frame to be locked
at multiple locations.
[0067] The base preferably has an outer dimension adapted to fit in an opening of the profile.
