Description

The present invention relates to a blade roofing device comprising a chassis receiving a lower series of slatted blades and at least one support superimposed on the frame receiving a higher series of blades mounted to louvre, the support being movable transversely to the long direction of the blades on the chassis to change the lateral position of the blades of the upper series relatively to those of the lower series, the blades passing from a position of full recovery when the roof is open to a recovery position partial when the roof is closed.

This device will particularly find its application in the field of balcony or terrace cover or to constitute a roof element for verandahs or other types of buildings.

At present, a roofing device is known for modulating and sunshine distribution of the document FR-A-2747707.

According to this document, a device is proposed to obtain a device for blade roof with ventilation.

Such a device is satisfactory in the distribution of the shadows and Sun. However, when total shade is desired, the roof is totally closed. This means that no air passage is allowed between the blades for ventilate the roof.

This is a limitation of the possibilities of use of such a roof: the user can not be totally sheltered from the sun or the rain while maintaining aeration through the roof.

The object of the invention is to remedy this drawback and proposes for this purpose make a roofing device where the blades have a traveling ability increased compared to current techniques.

In particular, beyond a transverse displacement, the blades can be movable in order to ensure the level shift and allow an air passage in the interstitial space.

Other purposes and advantages will become apparent from the following description.

The present invention relates to a blade roofing device, comprising a chassis receiving a lower series of slatted blades and at least a support superimposed on the chassis receiving an upper series of blades mounted to louvre, the support being movable transversely to the long direction of the blades on the chassis to change the lateral position of the blades of the upper series relatively to those of the lower series, the blades passing from a position of full recovery when the roof is open to a recovery position partial when the roof is closed, characterized in that it comprises means elevation of the support relative to the frame to allow air passage to through the roof even when the upper and lower blade series cover the entire surface of the roof.

The attached drawings are given as an indicative and non-limiting example. They represent an embodiment according to the invention. They will make it easy to understand the invention.

Figure 1 is a general view from above of a roofing device in a particular embodiment.

Figure 2 is a longitudinal sectional view of such a device.

Figures 3 and 4 illustrate a particular embodiment of the elevation means.

Figures 5 to 7 show schematic different configurations of opening or closing of the device shown here.

Figure 1 generally illustrates an embodiment of the roofing device shown here.

This device comprises a frame 1 on which are mounted various blades constituting a series of lower blades 2 visible in Figure 2. On the chassis 1 is mounted in a transverse direction corresponding to the perpendicular to the long direction of the blades, at least one support 3 adapted to receive a plurality of blades constituting an upper series 4 also visible in Figure 2.

Means of training, which can be manual or be constituted by a motor 17 according to the example of Figure 1 for one of supports 3, provide transverse mobility of the support 3 relative to the chassis 1.

Current guiding means will ensure the displacement of the support 3 by compared to chassis 1.

In particular, a support structure as presented in the document FR-A 2747707 may be suitable and applied in the present invention.

Due to the mobility of the upper blade series 4, it is possible to make to vary in a specific way or continuously the state of recovery of the series of blades lower 2 and higher 4. The shaded areas and the sun zones are thus modified at will according to the wish of the user.

In addition to this possibility, the present invention has the advantage of allowing the roof to be ventilated while maintaining complete protection from the sun or rainfall.

For this purpose, the device comprises means for raising the support 3 by relative to the frame 1. In doing so, the upper blade series 4 is raised by compared to the lower blade series 2 which allows the creation of a space interstitial between their respective levels.

According to a preferred embodiment, the elevation means comprise several carriages 5, for example four, distributed on the transverse edges of the support 3 to drive it in an upward movement relative to the chassis 1.

To do this the carriages 5 comprise at least one wheel 6 suitable for move transversely on a running surface secured to the frame 1.

To achieve the elevation, the running surface has two flat areas 7a for the lower level zone and 7b for an area at a higher level. Between these two zones 7a 7b, part of the rolling surface consists of a ramp 8 connection.

As is apparent from FIGS. 3 and 4, the wheel 6 of the carriage 5 is suitable for traveling the running surface from the lower flat area 7a to the zone upper plane 7b and this by a transition zone constituted by the ramp 8.

We understand that this design combines the movement transversal support 4 with that of the elevation.

To allow an air passage through the roof while maintaining complete protection from the sun and rainfall, it is important to adjust the measuring the displacement of the support 3 according to the size of the blades and their covering.

More precisely, the amplitude of the transverse displacement of the support 3 up to the foot of ramp 8 will be less than or equal to the recovery width of two superimposed blades.

By this particular choice of dimension and amplitude of displacement one can obtain a relative position of the blades of the lower series 2 and higher 4 such as shown in Figure 6.

It can be seen that no area of the roof is exposed to the outside and while that aeration is allowed.

Preferably, the support 3 comprises two longitudinal members on either side ends of the blades, the spars extending transversely and receiving each half of the carriages 5.

As shown in FIGS. 3 and 4, the rolling surface for the wheel 6 may include a shim 9 capable of constituting the upper level plane zone 7b and the ramp 8.

This shim 9 is positioned on a wing 12 mounted on the frame 1. way, it achieves very efficiently and cheaply the running surface.

Moreover, it will be advantageous to constitute stops 11a 11b to limit the amplitude of the movement of the carriage 5. For this purpose, a stop 11a such that represented in FIG. 4 makes it possible to limit the movement of the carriage when the support is in the lower position and an abutment 11b makes it possible to limit the movement of the carriage when the support 3 is in the raised position.

Figures 5 to 7 illustrate different relative positions of the series of blades lower 2 and upper 4.

FIG. 5 partially shows the roofing device in position totally closed. Figure 6 shows an intermediate position where aeration is allowed while protection from the sun and bad weather is preserved. Figure 7 shows a large overlap position between the blades of the upper series 4 and lower 2 allowing a wide opening of the roof device according to the invention to outside.

As shown in FIGS. 5 to 7, one of the series of blades and preferentially the two series 2, 4 or blades of triangular section.

In particular, an isosceles triangular section is preferred with a base 13 constituting the width of the blade and the isometric sides 14 constituting the two other sides.

It is advantageous for the blades to bear sealing means 16. These can be constituted by a seal mounted in a housing formed on one blades and applying by its other edge on a blade of the opposite series.

Figures 5 to 7 also illustrate a possibility for this purpose.

To carry the sealing means 16, the base 13 of the blades comprises a blade 15a 15b.

Moreover, the base 13 of the blades of the lower series 2 will be preferentially curved towards the interior of the roof to create a canal evacuation of water.

The roofing device thus presented is used in a very practical way.

It is sufficient for the user to operate manually or by a motor (by example an electric geared motor or a hydraulic system) the movement transverse support 3 relative to the frame 1.

According to the preferred embodiment of the invention, the transverse movement thus produced generates an elevation movement through the design particular of the running surface on which the wheels 6 of the carriages 5 are posed.

According to the state of progress of the transverse displacement of the support 3 on the frame 1, it is possible to modify at will the overlapping surface of the blades as well as the relative position of the upper blade series 4 with respect to the blade series lower 2.
