BE2017 / 5065

Damper to maintain the tension of a retractable sunshade fabric and sunshade equipped with it.

The present invention relates to a damper to maintain the tension of a retractable sunshade fabric.

More specifically, the invention relates to a type of awning with a roll-up cloth, the edges of which are slidably guided in a guide profile which is incorporated in a wall profile with which the guide profile can be fixed in a window opening or the like.

For guiding the edges of the fabric, the guide profile is provided with a slot through which the relevant edge of the fabric protrudes and wherein the edge is provided with a thickening that is wider than the width of the slot so that the fabric does not come out of the slot can be pulled, for example under the influence of the wind.

In order not to prevent sliding in the respective edge of the cloth, the guide profile is incorporated with a certain amount of play.

In case of wind gusts it can happen that the cloth starts to vibrate, which can cause noise and tear the cloth.

BE2017 / 5065

In known solutions, in known solutions, the guide profile is arranged in the wall profile with the use of dampers between the guide profile and the wall profile, which dampers are arranged on the guide profile and are provided with elastic lips on either side of the cloth that ensure that lateral tensile forces in the event of wind gusts or other forces exerted by the cloth on the guide profile, they are elastically absorbed by the dampers.

This prevents the cloth from tearing and the sound caused by vibrations or sudden blows from being muffled.

Such a solution is already known from WO2013 / 182956, in which the lips are provided with a clip-on foot with which they are clicked on either side of the guide profile onto the edges of the guide profile, which must also be provided with an adapted complementary click shape for this purpose.

A drawback of this is that the lips can detach from the guide profile and that the locking requires a lot of actions. In addition, the lips can be lost during assembly and the lips should be kept in stock as separate parts.

Solutions are also already known in which the dampers are made in one piece and are provided with a mounting body with two parallel hook-ribs facing each other with which the mounting body

B E2017 / 5065 in an assembled condition of the damper on the guide profile on both sides over the edges of the guide profile.

These dampers are pushed one after the other onto the guide profile and distributed over the length of the guide profile.

A drawback is that if a damper in the middle has to be replaced, all underlying or upper dampers must first be removed.

The present invention aims to solve the above and other disadvantages.

To this end, the invention relates to a damper to maintain the tension of the retractable fabric of a sunshade, the edges of the fabric of which are slidably guided in a guide profile with parallel edges, the damper comprising at least one elastic lip mounted on a mounting body with which the damper is the guide profile can be attached, the fixing body for this purpose being formed by two parallel inwardly directed hook-shaped ribs with which the fixing body can engage on both sides over the edges of the guide profile in an assembled state of the damper on the guide profile, the hook-shaped ribs mutually are connected by a connecting element, characterized in that the hook-shaped ribs are displaced in longitudinal direction relative to each other by a distance such that the

BE2017 / 5065 damper from the aforementioned mounted position on the guide profile can be turned away by a rotation through an angle about an axis transverse to the longitudinal direction of the aforementioned hook-shaped ribs.

An advantage of such a damper is that it can be loosened and replaced by a simple rotation.

This makes it possible to be able to replace an individual necessarily of several.

damper in the middle without the damper needing detachable parts

The damper is preferably made in one piece, so that fewer parts are required and the risk of loss of parts is smaller.

In this way, the damper is also stronger than in the case of a damper with lips that snap onto the guide profile.

To allow twisting, the distance by which the hook-shaped ribs have shifted relative to each other is such that, in at least one turned-away position, the distance between the hook-shaped ribs measured in a direction perpendicular to the longitudinal direction of the guide profile is equal to or greater then the width of the guide profile measured between the edges of the guide profile.

aforementioned

BE2017 / 5065

This makes it possible to easily pull the damper away from the guide profile from this turned away position because in that position the edges of the guide profile are completely removed from the hook-shaped ribs.

The connecting element is preferably simply designed as a substantially trapezoidal plate, the hook-shaped ribs being provided along two opposite edges of this plate.

Preferably, an elastic lip is provided on each of the hook-shaped ribs of the damper, which are preferably staggered relative to each other by sliding in the spring direction of the hook-shaped parts.

As a result, when mounting the dampers on the guide profile, two elastic lips are provided with one movement, which automatically assume a staggered position on either side of the fabric.

The invention also relates to a sunshade with a roll-up cloth, the edges of which are slidably mounted in a guiding profile which is incorporated in a wall profile with a side wall facing the cloth with a cloth in which the groove along which the guiding profile is arranged is the edge of the guide profile is incorporated in the wall profile by means of one or more dampers according to one of the preceding claims, which are mounted on the guide profile in such a way that they

BE2017 / 5065 lip or lips are directed towards the aforementioned side wall of the wall profile.

In order to better demonstrate the features of the invention, hereinafter, by way of example, without any limitation, some preferred embodiments of a damper according to the invention and of a sunshade equipped with such dampers are described, with reference to the accompanying drawings, in which :

figure 1 shows schematically and in perspective a sunshade according to the invention;

figure 2 shows on a larger scale a section according to line II-II in figure 1;

figure 3 shows in perspective the part indicated by arrow F3 in figure 2;

figure 4 shows on a larger scale a section according to line IV-IV in figure 3;

figure 5 represents a loose damper according to the invention as indicated by arrow F5 in figure 3; figures 6 and 7 respectively show a top view and front view according to arrows F6 and F7 in figure 5;

Figure 8 is a front view of Figure 3 but with multiple dampers in the assembled condition except a center damper in a twisted position; figure 9 shows a variant embodiment of figure.

The sunshade 1 shown in figure 1 comprises a roller box containing a roll-up shaft 3 with a vertical winding and 7

BE2017 / 5065 roll-off 4 screen, which is provided with a bottom bar 5 at the bottom and whose edges 6, in particular the side edges, are slidably mounted in two guides which in the example shown extend parallel and vertically downwards from the roller box.

The guides 7 comprise a wall profile 8 with which they can be mounted against a window or the like in a window opening or the like to be shielded from the sun.

A groove 10 is provided in the side wall 9 of the wall profile 8, which divides the side wall into two parts 9a and 9b and is bounded by two inwardly projecting wall parts 11a and 11b of the side wall 9.

In this case, the wall profile 8 is composed of two profiles 8a and 8b.

The wall parts 9a and 11a are part of the profile 8a, while wall parts 9b and 11b are part of the profile 8b. Thus, the slot 10 can be opened by separating the two profiles 8a and 8b from each other.

In the wall profile 8 there is an intermediate wall 12 which, together with the side wall 9, defines a space 13 which communicates via the slot 10 with the outside of the wall profile 8.

In the space 13 a guide profile 14 of approximately the same length as the wall profile is included and provided

BE2017 / 5065 of two parallel laterally projecting free edges 15 on either side of the slot 10.

The guide profile 14 has a width A which is larger than the smallest width B of the slot 10.

Centrally on a side of the guide profile 14 directed towards the slot 10, a slot 17 is provided through which a aforementioned edge 6 of the cloth 4 extends.

Said edge is provided with a thickening 18, for example in the form of a strip which is slid into the stitched edge of the cloth 4, and which has a width which is greater than the width of the slit 17, so that the said thickened edge 6 is not laterally drawn out from the slot 17 by a tensile force C exerted on the cloth 4 as shown in figure 2.

Between the guide profile 14 and the wall profile 8, one or more dampers 19 are provided, as shown in Figures 5 to 7, which are mounted on the guide profile 14 as shown in Figure 3.

In the example shown, the damper 19 is constructed in one piece with a mounting body 20 for mounting the damper 19 on the guide profile 14 and two curved lips 21 arranged on the mounting body 20 of an elastic material which, as shown in the cross section of Figure 2, are slightly compressed in the direction of the tensile force C and are thereby elastic

BE2017 / 5065 exert force on the inside of the wall parts 9a and 9b of the side wall 9 and thereby push the guide profile 14 away from the side wall 9.

The fastening body 20 is formed by two parallel inwardly directed hook-shaped ribs 22 arranged along two opposite edges of a connecting element 23 which in the example is mainly formed by a trapezoidal plate.

The distance I between the ribs 22 measured in a lateral direction perpendicular to the longitudinal direction X-X 'of the ribs 22 is smaller than the width A of the guide profile · 14.

The hook-shaped ribs 22 extend the full length of the aforementioned edges 24 of the trapezoidal connecting element 23 and are displaced relative to each other by a distance D as shown in Figure 7 to their positions longitudinally XX 'to positions staggered relative to from each other, the ribs 22 not overlapping in the lateral direction perpendicular to the direction X-X '. In other words, the distance D over which the ribs are displaced relative to each other is greater than the length E of the ribs 22.

The longitudinal ends X-X 'facing each other of the hook-shaped ribs 22 are pointed with a chamfered end 25 which encloses an acute angle F with the longitudinal X-X' of the hook-shaped ribs 22, the chamfered ends 25 being parallel to each other.

BE2017 / 5065

The distance G between the chamfered ends 25 measured in a direction perpendicular to the chamfer of these ends 25 is preferably equal to or greater than the width A of the guide profile 14.

An elastic lip 21 is provided on each of the hook-shaped ribs 22, which is fastened with a foot 26 to an upper end of the rib 22 and extends from this foot 26 over the length of the rib 22 away from the relevant rib.

Likewise, the lips 21 are displaced by a distance D relative to each other along the longitudinal direction X-X '.

In the assembled state of the dampers 19, the hook-shaped ribs 22 are preferably fixed to the guide profile 14 with a slight clamping.

The operation of a damper 19 is simple and as follows.

For example, when a tensile force C is exerted on the cloth 4 by a wind gust, the cloth 4 pulls the guide profile 14 along in the direction of the side wall 9, whereby the lips 21 are compressed between the guide profile 14 and the side wall 9, so that the tensile force C is elastically absorbed by these elastic lips, so that the cloth 4 will not tear.

BE2017 / 5065

In case a damper 19 should break and needs to be replaced, for example the middle damper 19 of figure 8, it is sufficient to rotate this damper 19 from its mounted position of figure 3 through an angle H around a geometric axis transverse to the longitudinal direction XX 'of the aforementioned hook-shaped ribs 22 up to the position shown in figure 8, wherein the sloping ends 25 are more or less aligned with the edges 15 of the guide profile 14.

The damper 19 of the guide profile 14 can then be removed from this rotated position in the direction Y-Y '.

It goes without saying that the guide profile 14 must first be removed from the wall profile 8, for which purpose, for example, the part 8b of the wall profile 8 must first be removed.

It is clear that the shape of the fastening body can be different and that the shape of the connecting element 23 can also deviate from a trapezium as illustrated in figure 9.

With respect to the shown embodiment of dampers of figure 7, the ribs 22 can be shifted even more than the distance D shown with respect to each other, so that when the dampers 19 are rotated, even more space is released between the ribs 22 and the ends 25 of these ribs may no longer have to be chamfered but can be finished straight. This is illustrated in Figure 9 where the distance D

BE2017 / 5065 is approximately equal to width A of the guide profile.

In more general terms, it can be stated that the distance D must be such that in at least one turned-away position the distance between the hook-shaped ribs 22 measured in a direction perpendicular to the longitudinal direction of the guide profile 14 is equal to or greater than the width A of the guide profile 14.

Although an elastic lip 21 is preferred on either side of the cloth 4 per damper 19, it is not excluded that one or more dampers can be provided with only a single lip 21.

The present invention is by no means limited to the exemplary embodiment shown in the figures, but a damper and a sunshield according to the invention can be realized in all kinds of shapes and sizes without departing from the scope of the invention.
