Abstract

The horizontal frame for a building facade comprises top (2) and bottom (1) rails. Fixed frames (3) applied on the internal face of the rail flanges located on the internal side of the faade delimit opening bays. Movable frames (4) which cover these bays are opened consecutively by projecting outwards and then translating laterally. The flange of the U section rails located inside the faade is higher than the height of the fixed frames. This enables the housing and free translation in the longitudinal direction of the faade of lower and upper springers, the height of which is inscribed in the height of the channel constituted by the rails' U section. The frame takes advantage of the size of modern architectural designs to house opening windows integral with the covered bays.

Description

 Joinery in horizontal strip comprising opening parts by projection towards the outside of the facade of the building then by translation in front of the adjacent fixed parts controlled remotely.

 The invention relates to devices for opening by projection towards the outside of the building and then by translation in a plane parallel to the facade, of a glazed frame to be included in a horizontal strip alternately comprising glazed or opaque fixed frames and movable glazed frames when the architecture implies that these frames are established in the same plane on either side of a hollow and narrow vertical joint and that the opening parts release the entire bay for a direct view of the outside.

We already know - request FR 95 02079 from two of the same inventors - a frame opening by projection towards the outside then translation in a plane parallel to the facade intended to equip smooth facades, but the operating mode of this chassis n 'authorizes only a partial opening of the bay.

Contemporary architecture frequently uses joinery in horizontal bands, the modenature of which is marked on the one hand by vertical and narrow hollow joints to be discreet, and on the other hand by the relief, on the contrary, marked by horizontal structures.

The object of the present invention is to exploit the volume of the horizontal structures of such an architecture in order to accommodate there an opening device different from that which makes the essential of the aforementioned request, in order to offer the user the possibility an integral opening of the bay controlled remotely in addition to all the previously exposed advantages of the exterior sliding projecting chassis.

The invention is explained below in detail using drawings showing the operating principle and showing only one embodiment.

Figures 16 and 7 are respectively a vertical section and a horizontal section on the lower base of the movable glass frame directly above the projection device when the latter is formed from a toothed belt.

In accordance with the present invention, the dormant part of the window strip is constituted by a bottom rail, the section of which has the shape of a U, the wings of which are directed upwards and the wing of which is situated towards the inside of the facade is higher than The other. by a top rail 2 of the same section, the wings of which are directed downwards. and by glazed or opaque frames 3 delimiting the bays to be opened and fixed as a wall mounted on the internal face of the wings located towards the inside of the heddle building 1 and 2.

The height of the fixed frames 3 is determined in order to provide a free space between their high and low edges and the bottom of the U-profile of the heddles 1 and 2 to make room respectively for the movable bed bases 5 and 6.

According to the present invention, the movable parts of the glazed strip consist of glazed frames 4, of the same height and thickness as the fixed frames 3, supported and guided in the lower part by a bed base 5 of length equal to the length of the frame mobile 4 which fits inside the heald 1 and whose section has the shape of a U whose wings are directed downwards, and guided in the upper part by a bed base 6 arranged symmetrically to the lower bed base 5 to inside the arm 2.

In order to support the movable glazed frame, the lower bed 5 of the same length as the movable glazed frame 4 is equipped at each of its ends with two rollers 7, located between the wings thereof on the same perpendicular horizontal axis at its length, which rest on the bottom of the rail 1.

In order to ensure the stability of the assembly, the position of the bed base and the spacing of the rollers are such that the vertical plane in which the center of gravity of the movable glass frame 4 is located remains inscribed between the rollers facing screw 7, whether the frame is closed or projected.

 The longitudinal displacement of one or other of the bed bases 5 and 6 which controls the translation of the movable glass frame 4 is guided, at each end of the bed base by rollers 8 located opposite each on a vertical and projecting axis of the wings of the bed base to rest on the internal face of the wings of the beams 1 and 2.

The upper box spring 6 is held inside the heddle 2 at each of its ends by two rollers 9 located on the same horizontal axis outside the wings of the box spring to bear on the lower part of a continuous channel 10 O fitted on the inside of each wing of the heald 2.

The same provisions applied to the lower base 5 and to the heald 1 prevent the lifting of the base 5.

 In accordance with the present invention, the lower bed base 5 has on its upper face in line with the rollers 7 a transverse sliding or rolling plate 11 on which a pad or a roller 12 rests secured to the movable glass frame 4 which allows its displacement in projection.

The displacement in projection of the movable glass frame 4 is controlled. in the vicinity of each of its four angles, by a lug 13 moving transversely in a light provided in the horizontal face of each of the bed bases 5 and 6 which it overflows to be engaged in a longitu-dinal fork 14 integral with the frame movable glass 4.

The displacement in translation of the movable glazed frame 4 is controlled by the longitudinal displacement of one of the bed bases 5 or 6 comprising, at any point along its length, on its horizontal face directed towards the movable glazed frame 4 a transverse bar 15 engaged in a transverse fork 16 secured to the glazed frame 4. The length of the drive bar 15 is such that it remains engaged in the fork 16 over the entire projection stroke of the movable glazed frame 4.

It can be seen from the above that all the operating members of the movable glass frame both in projection and in translation can be controlled by electro-mechanical means housed in each of the bed bases 5 and 6.

According to the invention, the projection pins 13 are controlled by a transverse endless screw 17 secured to the bed base 5 or 6 and engaged in a tapped hole in the part of the pin 13 located inside the bed base 5 or 6.

The two endless screws 17 contained in the same bed 5 or 6 are each actuated by an electric gear motor 18 comprising at its output a toothed wheel 19 engaged on a toothed wheel 20 secured to one of the ends of the endless screw. Depending on the weight of the movable glass frame, these two endless screws can be actuated by a single geared motor. To this end, the worms 17 will have at their end opposite to the gear 20 a gear 21 controlling a longitudinal toothed belt 22 ensuring the rich transmission between the worm 17 actuated by the single gear motor 18 and the other worm end 17 without engine.

In accordance with the invention, the control of the projection lug 13 may as well be provided by a toothed belt 23 with which it will be secured.

The toothed belt 23 housed transversely in the bed base 5 or 6 between two toothed wheels 24 whose axes are horizontal, located in the same horizontal plane and parallel to the length of the bed base. will be actuated by a geared motor 25 directly attacking one of the toothed wheels 24. Depending on the weight of the movable glass frame. the two notched belts 23 contained in the same bed base 5 or 6 can be actuated by a single geared motor. To this end, the two toothed wheels 24 situated on the same longitudinal axis and not subject to the geared motor will be coupled by a transmission shaft 26 ensuring the synchronous operation of the two lugs 13.

According to the invention, the translation of the bed base 5 or 6 controlling the translation of the movable glazed frame 4 is actuated by a geared motor 27 comprising at its output a toothed wheel 28 engaged on a longitudinal rack 29 secured to the heald 1 or 2.

In the case where the presence of the drive shaft 26 would not allow to have the geared motor 27 on an axis perpendicular to the length of the box spring 5 or 6, a bevel gear will be inserted between the geared motor then located on a longitudinal axis and the toothed wheel 28 engaged on the rack 29.

Finally, in accordance with the invention, the electrical supply to the command and control members contained in the box springs is ensured by an electric cable 30 secured to one of its ends of the rail 1 or 2 at the bottom of the channel 10 to the right of one of the sides of the opening bay, then passing over a pulley 31 whose axis is horizontal and which moves freely along the rail 1 or 2 at the bottom of the same channel 10 to return to the connector 32 located at one of the ends of the bed 5 or 6. In order to keep the electric cable 30 in tension, a non-electric cable 33 is arranged symmetrically to the previous one and the pulleys 31 mounted on the same slide 34.

It can be seen from this latter arrangement that the travel of the slide 34 is equal to half of the travel in translation of the movable frame 4 and allows, from an adequate adjustment of the initial position of the first, to have: in a direction of translation of a stroke of the movable frame 4 such that it comes exactly in alignment with the fixed frame 3 adjacent if the latter is of the same length. and in another direction of translation of a stroke of the mobile frame 4 close to its length.

The example given of an realization in aluminum joinery shows the different specific qualities of this product: the functioning of the opening is not dependent on the size of the lit room, and therefore a remote and centralized control is possible for the complete closing of the unoccupied building, for the opening in the event of smoke detection, for the closing of the bays when the air conditioning is put into service, etc. in addition to an individual order.

the translation of the bays can be done in both directions in order to facilitate cleaning of the external faces of both mobile frames and adjacent fixed frames, the box springs containing almost all of the bodies subject to maintenance can be removed without opening the bays, the movable frames can from the interior of the building be provisionally subject to the frame in the same way as the fixed frames and the box springs extracted after removing the external covers, by shifting the bed base 5 or 6 after removing the drive bar 15.
