Abstract

The sunshade has a series of strips (300), each comprising a set of slots extending on its entire length. Two of the slots receive threaded rod that serves to fix the strip to a receiving wall (110) of a vertical post (100). Ends of the two rods are fixed to a plate (400) that forms intermediate unit between the strip and the post. The plate extends transversal to the direction of the strip for covering its end.

Description

The invention relates to sunscreen arrangements based on earth cooked, that is to say the arrangements positioned for the recovery of windows of buildings, to stop or filter the sun's rays, and to presenting in the form of a series of terracotta blades.

So far, terracotta blades, also very resistant natural shocks and aggression (wind, snow and other inclement weather) have been considered as a material fulfilling the safety criteria due.

On this theme, efforts have been focused on the choice of particularly robust materials.

However, it remains desirable to further improve the safety of the use of such sunscreens.

In particular, it is necessary to foresee an extreme case where despite the high resistance of the blades, one of them should collapse accidentally, especially in extreme weather conditions or of choc.

It is the object of the invention to provide a solution to this problem specific.

US Pat. No. 5,490,353 discloses a sun visor consisting of wooden blades traversed from one side by a stem. It can not to provide a solution to the problem of the constitution of sun visors ceramic, because wooden boards may be splitting; But in no way break as is likely to do a blade in ceramic.

In US Pat. No. 6,014,839, a sun visor consisting of ceramic blades; but which have no internal armature and are fixed only by fastening means at their ends. It is obvious that if such blades break, their pieces will fall and risk of seriously injuring persons below, and this especially for tall buildings.

It is physically impossible to arrange a rod such as of the wooden blade of US Pat. No. 5,490,353 to the interior of the blade ceramic of US Patent 6,014,839.

According to the present application the solution lies in the fact of propose, a sunshade consisting of a series of superimposed each having the shape of a terracotta blade, these floors being arranged parallel to each other so as to form a barrier stopping a portion of the light rays arriving on such a solar shading, also comprising means for maintaining this series of stages in this superimposed configuration, each stage being constituted by a blade unique from the same block of matter, and in that this blade is traveled by at least two internal frames on all of his length.

For this, each blade must not be full, but, so similar to a hollow brick, be provided throughout its length with several reservations or parallel cells; so that it is possible to put the reinforcements or rods into these reservations or cells.

In the examples that will be described below, only two rods are threaded into two cells; but it is possible to have more two.

The sunshade here proposed consists essentially of a series of blades 300 superimposed on each other in parallel manner with each other and slightly oblique towards the plane of the window covered. This series of blades 300 is coupled to two uprights Vertical 100 and 200 receiving and maintaining this series of blades.

Maintaining the blades 300 is therefore performed by each of the two ends of each blade concerned.

The blades 300 are made here of terracotta (or ceramic) on an extension of 1.20 meters in one piece. However an extent superior, for example 2.80 meters will be considered here too as widely acceptable.

These blades are similar to hollow bricks, that is to say that they comprise hollow volumes, called reservations or cells, which extend over their entire length.

This type of sunshade, certainly suitable for any type of window, is however adapted mainly on the facades of strong buildings height.

This sunshade is configured for room-by-room mounting on the facade for which it is intended. Also the installation is carried out first by fixing the two vertical uprights 100 and 200 on the facade, then by engagement of the blades on these amounts.

For this purpose, each blade is equipped with means of engagement and locking of the latter on the amounts.

These means, shown in more detail in FIGS. 3 and 4 (first variant), consist essentially of a plate 400 forming an organ intermediate between the blade 300 considered and a vertical upright 100. This plate 400 extends transversely to the direction of the blade 300 to cover the end of the latter.

Of substantially square configuration and the same width as that of the amount 100, the plate 400 is traversed by a blade end on a diagonal of this square.

In the external face, that is to say facing the vertical amount, the plate 400 has a central appendage 410 forming an extension of the blade end through the vertical upright 100. This appendix 410 therefore forms a gripping element of the blade 300, transmitting the weight of this one on the vertical amount 100.

This appendix 410 here consists of a pair of metal blades 412, 416. Each pair of metal blades 412, 416, integral with the platinum 400 by welding, forms two parallel portions, then departs at its ends, thus forming an enlarged area.

Each metal blade 412, 416 is thus extended to its free end by a wall portion directed in lateral spacing, for with respect to an accidental longitudinal exit of this appendix 410 out of the amount 100.

Attachment Appendix 410 has a longitudinal extent greater than the thickness of the receiving wall 110 on the vertical upright 100.

Thus a possible difference in positioning vertical uprights is compensated by a corresponding offset of the wall point on this external appendix 410. The extent of the end appendix 410 forms therefore a range of cooperation sufficiently wide to compensate the uncertainty of positioning of the uprights 100, 200 encountered in the practice of facade work.

In other words, the blade 300 is put in place by one and same movement of applying the latter laterally on its two uprights 100 and 200, having the effect of sliding the longitudinal extensions 410, present at both ends, towards inside each vertical upright 100, 200.

Such a plate 400, previously secured to the blade 300 considered, is therefore put in place on the amount 100 per displacement of this longitudinal appendage 410 according to a lateral movement of the blade 300 and its extensions 410, making each extension 410 move within a lateral cutout of the vertical upright 100.

The cutting extends for this, first horizontally (section 112), and further has an inner termination in the form of a portion 114 extending vertically to a bottom 116 below, forming the final receiving well of this extension 410.

This vertical termination 114, at bottom 116, presents a width of circulation substantially equal to the width of the appendix 410.

Once thus put in place, the plate 400 is secured to the side considered the amount 100 by screwing, here by two bolts and two corresponding nuts.

The preliminary assembly between each plate 400 and its blade 300 corresponds to two internal appendices 440, 450, extending from the platen inside the blade 300.

These two internal appendices 440, 450 are configured under the form of sleeves each having a length of a few centimeters. At the blade shaping stage, two reservations are arranged within the area of one end of the blade 300, under the form of two corresponding cylinders.

In addition to the pair of sleeves 440, 450 introduced into the housing end of the terracotta blades, a series of reservations longitudinal or alveolus traversing the entire length of this 300 blade.

These reservations or alveoli extending transversely, are planned to reduce the weight of the blade and allow for drying as well that a cooking without appearance of cracks. But in the case of the present invention, these cells will, above all, make it possible to introduce supports 500.

Two of these reservations or alveoli spanning the entire length of blade 300 receive a threaded rod 500 (type "M10 by example. In addition to its path inside the blade 300, each rod threaded 500 is further introduced within each inner sleeve 440, 450 platinum to engage it by a cooperation type screw nut.

To allow this platinum / rod cooperation, each sleeve 440, 450 has a diameter slightly greater than that of a threaded rod 500. Beyond the sleeve, the plate has a housing for the receiving a nut 470 which engages the threaded rod.

This nut 470 thus tends to push the plate 400 against the end of the blade.

Screwing the two nuts placed at the ends of each rod threaded thus tends to secure the two plates 400 against the ends of the blade.

The stems 500, here two in number, have for essential role to ensure the safety of persons and equipment in below such a sunshade.

Indeed, these threaded rods 500 fulfill their safety role during accidental damage to a blade.

Such damage, although very rare, may indeed appear during unforeseen weather conditions, such as wind or snow out of the ordinary, or projectile shock.

The blade 300, when broken, remains retained by the rods 500. stems retain broken elements, preventing them from coming hitting equipment or people below.

In addition to this role of restraint following damage, the rods 500 also produce a maintenance of the whole in a form that is ready for implementation in a monobloc way, since the turntables are held together with the blade.

It would not be possible to set up the blade 300 by means of of a single threaded rod, because it does not have the same dimensions, nor the same shape as the cell in which it would be inserted, the blade 300 would turn around the stem 500. However, it is necessary that its angular position is immovably determined, which can only be done by employing minus two stems 500.

In addition, the 500 rods also have the role of facilitating the implementation of place of the blade, maintaining the elements of grip in situation operational.

There is shown a more elaborate variant of platinum in FIGS. to 8, in which the association between the threaded rods 500 and the plate 400 is provided with means of damping possible constraints due to differential thermal expansions or inaccuracies dimensions between assembled parts.

In this variant, the threaded rod 500 is not secured directly to the turntable, but is linked to it via of a member 460 forming an expansion joint, and comprising for this a longitudinal section of elastomer material accepting offsets lengths between the actual length of the rod 500 and the actual spacing between plates 400.

In other words, the threaded rod 500 has an end coming to become solid with this elastomer piece 460, and this elastomer piece 460 itself extends the threaded rod 500 to connect it to the plate 400.

For this the elastomer piece 460 which has the shape of a stud cylindrical is equipped at both ends with threaded rod portions 462 and 464. One of these threaded rods, referenced 462, is screwed through the platen wall to a corresponding nut 470. The opposite threaded rod 464 is screwed into a sleeve 480 which also receives the threaded rod longitudinal 500.

This coupling sleeve 480 therefore has two threads internals extending to each other, the first thread being selected for the screwing with the extension 464 of elastomer piece and the second thread, of wider diameter, is provided for receiving the threaded rod longitudinal 500.

Thus, a difference in length between the threaded rod 500 and the earthen blade 300 is translated either by stretching the elastomer piece 460 or by a contraction of it, according to the direction of the thermal gap encountered between these two pieces.

This piece 460 also fulfills the role of compensating for possible dimensional differences in mounting, and dampen any vibrations mechanical between blade and post, including acoustic vibrations. This piece 460 thus participates in producing a sound insulation effect of the solar shading as a whole.

Note that in this configuration, the sleeve 440, 450 intended to be introduced into the blade 300, is equipped with an outer sheath 490 made of flexible plastic material, typically rubber.

This sheath 490 has an inner shape complementary to the sleeve it surrounds, ie a main part 492 of shape cylindrical, extended by a second part 494, shorter length and wider diameter for receiving an enlarged base 445 of the muff.

This enlarged base 445, which is therefore surrounded by rubber, stays out of the terracotta blade, and forming a stop longitudinal blade.

Between its two portions 492 and 494, the sleeve 490 therefore covers, by its transverse portion 495, the base 445, that is to say the stop longitudinal blade.

The sheath thus also forms, by this transverse portion 495, a longitudinal damping joint that absorbs these possible expansions differential between blade 300 and rod 500. The mechanical absorption produced by this portion 495 is also intended to dampen mechanical vibrations likely to appear between the blade and the post, and in particular acoustic vibrations, this portion 495 participating in the isolation function sound of the sunshade.

The attachment appendix 430 this time presents a configuration in cylinder, in the form of two half-cylinder walls 434, 436. Each wall in half cylinder 434, 436 is seen, here also, extended to its free end by a wall portion 435, 437 directed in spacing side for restraint with respect to an accidental longitudinal exit of this Appendix 430 out of the amount under consideration.

Note that this type of placement of the blades 300 by a Lateral movement of these towards the front facilitates highly installing the blade. This arrangement is therefore advantageous in itself, regardless of any consideration of internal reinforcement.

It will also be noted that in this embodiment (FIGS. 7, 8), the attachment appendix 410 presents, here again, an extension longitudinal greater than the thickness of the receiving wall 110 of the upright amount 100. Preferably, the same configuration is adopted at the opposite end of the blade.

The uprights 100 and 200 are mounted in front with a spacing that corresponds to a positioning of their receiving wall lateral 110 specifically centered in the middle of the appendages 430.

A possible difference in the positioning of the vertical uprights is then offset by a corresponding shift in the fulcrum of this wall 110 and / or its corresponding wall at the opposite end.

The extent of the end appendix 430 forms a range of sufficiently extensive cooperation for the associated support wall in order to compensate for the positioning uncertainty of the uprights 100, 200. The inaccuracies typically encountered in the work of facade, in spacing or approximation of vertical uprights, are compensated by such a tolerance range of the support of a few centimeters at each end.

Finally, after placing the blade 300, screwing the plates 400 on the uprights 100, 200 ensures the final positioning to against longitudinal movements that would otherwise be permitted by this longitudinal positioning range.

In addition, in an embodiment for avoiding an offset final unwanted by this screwing, we adopt a platinum and at least one both of which cooperate with the thread of the screw, so that the pre-existing gap before screwing is not modified by the clamping operation of the screw.
