Definitions
- the present invention relates to a sunshade for covering a terrace or the like in order to protect it from sunlight and rain.
- the invention relates to a sunshade comprising slats which are rotatable about their longitudinal axis between a horizontal position in order to provide maximum shading from the sun and a tilted position in order to allow the maximum amount of sunlight through and the ends of which are displaceably held between two parallel guiding beams in order to move the slats in the tilted position towards one end of the guiding beams in order to provide the largest possible opening between the guiding beams and to allow the maximum amount of light through when this is desired.
- sunshades are relatively complex and as a result relatively expensive and are additionally easily susceptible to wear and obstructions owing to the complexity.
- a further drawback is that the system for rotating and displacing the slats is relatively large and is therefore difficult to integrate into the guiding beams, as a result of which a considerable portion of the system is visible or the guiding beams are unnecessarily large, which mars the aesthetic appearance of the sunshade.
- a sunshade according to the preamble of claim 1 is disclosed by GB 2 480 141 A .
- the invention relates to a sunshade comprising slats, wherein each slat is rotatably arranged in a sliding element at each of its two ends, which sliding element is displaceable in or on a guiding beam and at least one of the two sliding elements of each slat being provided with a transmission between a drive shaft for the rotation of the slat and the relevant end of the slat and wherein each guiding beam is provided with a drive for displacing at least one of the sliding elements which pushes and/or pulls at least some of the other sliding elements during the displacement, for which purpose a carrier mechanism is provided between each of the sliding elements.
- An advantage of a sunshade according to the invention is that, in addition to the advantage that the opening can be cleared completely or virtually completely, the transmission and the carrier mechanism can be embodied in a simple and compact manner.
- An additional advantage in the case of a sunshade comprising slats is that the drive for displacing the sliding element does not have to be coupled to the transmission for the rotational movement of the slats and the rotational movement may preferably be carried out independently of the movement of the sliding elements, which entails a greater flexibility of possible positions and intermediate positions when using the sunshade.
- the guiding beams are formed by a profile having a chamber in which the sliding elements, the transmission and optionally the carrier mechanism and/or the drive are held or arranged so as to be concealed, possibly with the exclusion of a groove in the wall facing the slats in order to allow the ends of the slats to move.

Description
- The present invention relates to a sunshade for covering a terrace or the like in order to protect it from sunlight and rain.
- More specifically, the invention relates to a sunshade comprising slats which are rotatable about their longitudinal axis between a horizontal position in order to provide maximum shading from the sun and a tilted position in order to allow the maximum amount of sunlight through and the ends of which are displaceably held between two parallel guiding beams in order to move the slats in the tilted position towards one end of the guiding beams in order to provide the largest possible opening between the guiding beams and to allow the maximum amount of light through when this is desired.
- A significant drawback is that such sunshades are relatively complex and as a result relatively expensive and are additionally easily susceptible to wear and obstructions owing to the complexity.
- A further drawback is that the system for rotating and displacing the slats is relatively large and is therefore difficult to integrate into the guiding beams, as a result of which a considerable portion of the system is visible or the guiding beams are unnecessarily large, which mars the aesthetic appearance of the sunshade.
- An additional drawback of the known sunshades comprising slats is that the rotational movement and the sliding movement of the slats are not always independent of one another and that the rotation angle of the slats is relatively limited. A sunshade according to the preamble of claim 1 is disclosed by
GB 2 480 141 A - It is an object of the present invention to provide a solution to at least one of the aforesaid drawbacks and to other drawbacks.
- To this end the invention relates to a sunshade comprising slats, wherein each slat is rotatably arranged in a sliding element at each of its two ends, which sliding element is displaceable in or on a guiding beam and at least one of the two sliding elements of each slat being provided with a transmission between a drive shaft for the rotation of the slat and the relevant end of the slat and wherein each guiding beam is provided with a drive for displacing at least one of the sliding elements which pushes and/or pulls at least some of the other sliding elements during the displacement, for which purpose a carrier mechanism is provided between each of the sliding elements.
- An advantage of a sunshade according to the invention is that, in addition to the advantage that the opening can be cleared completely or virtually completely, the transmission and the carrier mechanism can be embodied in a simple and compact manner.
- An additional advantage in the case of a sunshade comprising slats is that the drive for displacing the sliding element does not have to be coupled to the transmission for the rotational movement of the slats and the rotational movement may preferably be carried out independently of the movement of the sliding elements, which entails a greater flexibility of possible positions and intermediate positions when using the sunshade.
- In a preferred embodiment, the guiding beams are formed by a profile having a chamber in which the sliding elements, the transmission and optionally the carrier mechanism and/or the drive are held or arranged so as to be concealed, possibly with the exclusion of a groove in the wall facing the slats in order to allow the ends of the slats to move.
- This has the advantage that the sunshade can be embodied in an even more compact and less fragile manner, with all of the associated advantages.
- According to a preferred feature of the invention, the ends of the slats at the location of one guiding beam are lower than the other end of the slats in order for rainwater to be able to flow away towards said guiding beam.
- This has the advantage that the rainwater effectively drains away and prevents rainwater from remaining on the surface of the slats when they are in the horizontal position and from undesirably falling through the slats when they are tilted upwards.
- With a view to giving a more detailed description of the features of the invention, a number of preferred embodiments of a sunshade according to the invention are described below by way of non-limiting example with reference to the attached drawings, in which:
-
Figure 1 diagrammatically shows a perspective view of a sunshade according to the invention; -

Figure 9 shows a cross section such as the one from -
Figure 6 , but for the embodiment ofFigure 8 ; -
Figure 10 shows a cross section ofFigure 9 , but for another position of the slats. -
Figure 11 shows another particular embodiment of the present invention in which a tube motor is used. - The sunshade 1 diagrammatically illustrated in
Figures 1 to 4 comprises a construction having aframe 3 which is arranged onposts 2 and comprises two guidingbeams 4, 5 which are connected to one another by two transverse beams 6, 7. - In this case, the sunshade 1 is embodied as a shelter or awning, with
slats 8 being arranged between the guidingbeams 4 and 5 for this purpose, which slats extend parallel to one another and at right angles to the guidingbeams 4 and 5 and with theslats 8 being rotatable about their longitudinal axis X-X' and displaceable in a direction parallel to the guidingbeams 4 and 5, as illustrated by the arrows P and P' inFigure 1 . - The guiding
beams 4 and 5 are embodied as a profile having aninternal chamber 9 and in this case also having agroove 10 in the side 11 facing theslats 8. - In the example illustrated in
Figure 1 , theslats 8 are distributed proportionally over a certain length A of the guidingbeams 4, 5, with theslats 8 being rotated so that sunlight can pass between theslats 8. - One guiding beam 5 is higher than the other guiding
beam 4, as a result of which theslats 8 are oriented obliquely downwards and oneend 12a of theslats 8 is lower than theother end 12b. - The guiding
beam 4 on the side of the lowest end is provided with adrainage gutter 13 which extends underneath theend 12a of theslats 8. -
Figure 2 illustrates in more detail a part of a guidingbeam 4, with part cut away so that the mechanisms for moving and rotating theslats 8 are clearly visible. - The slats are provided with a
shaft 14 at the twoends elements 15. - The
sliding elements 15 are situated in thechamber 9 of the guidingbeam 4 and are in this exampleprovided witha a guide 16 e.g. a wheel or a sliding piece by means of which they are guided in a guidinggroove 17 of the guiding beam which extends over the entire length of the guidingbeam 4. - In this case, two successive
sliding elements 15 are connected to one another by means of acarrier mechanism rods end 21 to one of the two slidingelements 15 in such a way that it can rotate freely about apivot pin 22. - The two
rods other end 23 by means of alink 24 which is rotatably connected to each of theseends 23 via apivot pin 25. - In this case the
rods ends end 21 and a toothing 27 at theother end 23. - As can be seen in
Figure 4 , the toothings 27 of, for example, therods toothings 26 at theother end 21 of therods rods adjacent carrier mechanisms Other carrier mechanisms 18 comprisingrods - The
chamber 9 also contains abelt drive 28 which is composed of abelt 29, preferably a toothed belt, which is connected to one singlesliding element 15, for example the first slidingelement 15a inFigure 4 which is the furthest away from the transverse beam 7, with the connection being diagrammatically illustrated by crosses. - The
belt 29 is guided over adrive wheel 30, preferably a toothed drive wheel which can interact with the toothed belt, at one end of the guidingbeam 4 and is guided over a reversingwheel 31 at the other end of the guidingbeam 4. - The
drive wheel 30 is coupled to a drive mechanism, for example in the form of amotor 32 having ashaft 33 on which thedrive wheel 30 is fastened or in the form of a manually driven winding mechanism. - A
transmission 34, which is illustrated inFigures 3 and4 , is provided in eachsliding element 15 of the illustrated guidingbeam 4, whichtransmission 34 is driven by means of acommon drive shaft 35 for alltransmissions 34 and which transmissions are in this case embodied in such a way that they allow theslats 8 to rotate through a large angle, preferably through a complete revolution of 360°. - The
transmissions 34 are composed of aworm mechanism 34 comprising aworm wheel 36 which is displaceable over the abovementionedcommon drive shaft 35 and which engages with agear wheel 37 which is mounted in the slidingelement 15 and is coupled to an end of aslat 8 to be driven. - The
gear wheel 37 is provided with a non-circular cutout in which theshaft 14 of theend 12a of aslat 8 is held such that it cannot rotate, whichshaft 14 is provided with a suitable corresponding cross-section for this purpose. - According to the embodiment shown in
Figure 2 , thedrive shaft 35 is provided with alongitudinal slot 38 and worm wheel itself is provided with acarrier 39 in the form of a pin which engages with theslot 38. This arrangement allows to transmit the rotational movement of thedrive shaft 35 to thewormwheel 36. But other mechanical solutions may be envisaged in which the drive shaft has a non-circular cross-section. - A
motor 40 which is coupled to thedrive shaft 35 provides a common drive for theslats 8 or at least some of them. - The fact that all of the components are arranged in the guiding
beam 4 ensures that they are hidden from view and that they are protected from potential damage caused by, for example, the influence of the weather or by vandalism. - The operation of the sunshade 1 is very simple and is described below and illustrated with reference to
Figures 4 and5 , in whichFigure 4 illustrates a position similar to that ofFigure 1 , with thesliding elements 15 being pushed away from one another and theslats 8 being tilted into an open position allowing light to shine between theslats 8. - Starting from this position in
Figure 4 , theslats 8 can be rotated in the direction of arrow R illustrated inFigure 5 into a horizontal position by driving thedrive shaft 35 in a certain direction of rotation of the arrow Q, more specifically into a position in which the slats come to rest against one another and form, as it were, a closed roof without the displacement of the sliding elements. - As one
end 12a of theslats 8 is lower than theother end 12b, the rainwater which falls on theslats 8 will run off in the direction of the guidingbeam 4 and thus into thedrainage gutter 13. - It will be clear that the
slats 8 may be tilted upwards again out of the position inFigure 5 into a position illustrated inFigure 4 by activating themotor 40 in the opposite direction of the arrow Q. - In order to open the space between the guiding beams to the greatest possible extent starting from the situation in
Figure 4 , theslats 8 can be displaced to one end of the guidingbeams 4 and 5 in the direction of arrow P towards the transverse beam 7 by using thebelt drive 28. - For this purpose, the
belt 29 is driven in a direction in which the firstsliding element 15a is moved in the abovementioned direction of the arrow P towards said transverse beam 7. - This causes the first sliding
element 15a to be displaced towards the second slidingelement 15b, as a result of which therods carrier mechanism 18a between the first and the second slidingelement - The rotational movement of the
toothing 26 on the end of therod 20a of thiscarrier mechanism 18a also causes thecarrier mechanism 18b between the second and the third slidingelement toothings 26 of therods element 15b. - In this way, each
carrier mechanism following carrier mechanism sliding elements 15 moving towards one another in a synchronous and proportional manner until the moment when either theslats 8 or thesliding elements 15 come to rest against one another as illustrated inFigure 6 , in which the space between the guidingbeams 4 and 5 is open to the greatest possible extent in order to let the maximum amount of light through. - When the
belt 29 is driven in the opposite direction thesliding elements 15 are moved apart from one another in an analogous manner, with the slats moving simultaneously and synchronously. - In each intermediate position, the
slats 8 may be rotated into a position in which they are more closed, for example into a position where they rest on one another in the manner of roof tiles, both during the movement of thesliding elements 15 and when thesliding elements 15 are in a stationary position. - It will be clear that it is not necessary for all
slats 8 to be displaced to one single end of the guidingbeams 4 and 5 in order to open the blind. It is thus possible, for example, to divide theslats 8 into two series, with one series ofslats 8 being displaced to one end and the other series being displaced to the other end of the guidingbeams 4 and 5. In this case, it is obviously necessary to provide twobelt drives 28, one for each series ofslats 8, with in that case the two central slidingelements 15 being attached to thebelt 29. - The two
belt drives 28 could then preferably be driven independently of one another, as a result of which the sunshade could be used in two separate parts, as it were. - In that case, it is preferable to carry out the rotation of the two series of
slats 8 separately by means of acommon drive shaft 35 for each series ofslats 8, although the use of onesingle drive shaft 35 for both series of slats is not precluded. -
Figure 7 illustrates a cross section of a variant embodiment, wherein in this case thecarrier mechanisms 18 are arranged on the other side of the slidingelements 15 and the figure also shows that in this case the illustratedslat 8 is driven in rotation by atransmission 34 in the sliding element on the left, while on the other side the end of theslat 8 is mounted in a slidingelement 15 withouttransmission 34 such that it can freely rotate. - In this case, all sliding
elements 15 in the left-hand guiding beam 4 are provided with atransmission 34 on acommon drive shaft 35, whereas the slidingelements 15 in the right-hand beam 5 have no transmission so that a drive shaft is not needed in this beam. - Each
beam 4 and 5 is provided with abelt drive 28 for the sliding movement of the slidingelements 15. -
Figures 8 to 10 illustrate a variant of a sunshade according to the invention which is substantially analogous to the embodiment described above but with the difference that thecarrier mechanisms 18 between the slidingelements 15 are composed of acable 41, the ends 42 of which are fastened between each pair of successive slidingelements 15 and which is long enough to be able to move the sliding elements apart from one another over a distance. - The operation of this sunshade 1 is analogous to that of the previously described sunshade of
Figure 2 , with the difference that theslats 8 will not move simultaneously and synchronously when one of theslats 8 is displaced, but that when the first slidingelement 15a is displaced in the direction of the arrow P it will push the other sliding elements together in sequence one after the other until all of the slidingelements 15 have been pushed together in the position ofFigure 9 . - When the first sliding
element 15a is displaced in the opposite direction P', first of all the second slidingelement 15b, then the third slidingelement 15c and the following sliding element will be pulled along like carriages in a train until the first slidingelement 15a reaches the transverse beam 6 at the other end of the guidingbeams 4 and 5. -
