Description

 The present invention relates to a thermal break window with one or more sliding-lwun leaves in front of the other, the frame and the intermediate uprights are made of aluminum, and the framing of the insulating glazing of the plastic leaves. Electronic and electro-magnetic equipment ensures the prevention of any break-in with sound, light or other deterrence.

All aluminum sliding sash windows with thermal break on the market have the following disadvantages
10) The profiles used for their manufacture must include several thermal breaks.

 20) They are numerous and their interdependence requires constantly balanced storage in order to avoid any stoppage of production.

 30) The resins used in their manufacture are often very rigid and cannot be used in addition.

 40) The framing of the insulating glazing of the leaves is treated according to the same process and its execution according to the same solutions.

 50) The current building regulations stipulate that all dry rooms in an apartment must be self-ventilated.

However, no existing thermal break profile offers the possibility of creating ventilation in its section, without this ventilation being detrimental to its thermal insulation.

 60) Current joinery is rarely mixed and is never designed to use a combination of aluminum and a synthetic material.

 70) Likewise, they very often have a well-defined job, and can rarely, inexpensively, be used in both new buildings and renovations.

 9) Finally, they are never equipped with an inaccessible electronic and electromagnetic assembly, both internally and externally, ensuring the. prevention of any break-in.

The window which is the subject of the present invention overcomes these drawbacks and is presented in the following manner
The dormant frame of the entrance as well as the intermediate uprights are executed using aluminum profiles that do not have a thermal break. The sleeping frame is made up of two rectangular frames each assembled by miter cut with crimping angle.

 The lower cross member and the right and left uprights of each of the frames are executed with a rectangular tubular profile having on its largest dimension, two wings forming a U intended to receive the sliding leaves.

 The upper crossmember is made with an identical profile but amputated by a wing to allow the installation of the leaves. A square-shaped profile, having the same characteristics as the removed wing, comes after this installation, to be screwed onto the flat of the tubular part in order to close the profile. The tubular part also serves as a housing for the crimping bracket for the cross-sectional assembly of tabs of each of the frames.

The two manufactured frames are applied one against the other, identical face to identical face with the space necessary for the installation between them of a peripheral seal in flexible elastomer intended for the thermal insulation of the whole. This joint has the shape of a T
The vertical part is tubular and the full horizontal bass, is designed to hold in place, on the aluminum profiles to which it is glued, a brush type "Fin Seal", ensuring the watertightness of the leaves. outside the sleeping frame completes the sealing of the assembly.

 The final assembly is carried out by placing around the outer periphery of the sleeping frame, plastic parts sliding in ribs provided for this purpose in each of the profiles of the two frames.

 These parts can be consolidated in their final position by the use of blind rivets. If necessary, they can also, above the upper crossmember, be replaced by profiles of the same material, designed to ensure self-ventilation of the premises.

 In the upper and lower horizontal lengths, at the meeting point of the leaves in the closed position, the peripheral seal of thermal insulation in flexible elastomer is interrupted to be replaced by two plastic parts of rectangular section. These parts are designed to receive in the upper part and low, the buckets of the embedded rods of the intermediate uprights.

The part located in the upper part also serves as a housing for the electro-magnetic system for blocking the internal upright and for the electronic system for preventing the break-in of the glazing and of the two uprights.

 Finally, to facilitate the installation and the bonding between the two frames of this joint, the miter cut assembly of each angle is executed with the help of a plastic square fitting into the tubular part.

 The intermediate uprights in the form of angles with unequal wings ensuring the closing of the leaves, are mounted on the frame and form an integral part of it. They are fixed to the latter in t8te-spade-portion and projecting from its opposite faces, in the axis of closure of two leaves sliding one in front of the other.

 In the closed position, the small wings of the profile are parallel to these faces and the large ones are closed on the sliding leaves.

 In the open position, the large wings move apart from one another to free the leaves and allow lateral movement of these. However, the inner leaf can be operated independently of the outer one.

 The uprights are placed on the sleeping frame using four identical aluminum parts. These parts are made from scrap from the profile used for the manufacture of the uprights. They are fixed in the upper part on the angle-shaped profile screwed on the upper cross-member and in the lower part on the wing of the lower cross-member. These intermediate uprights are tubular aluminum profiles without thermal break. They have the shape of an angle bar with unequal wings with at the end of each of them, an open tube with close edges. In the tube of the smallest wing, is fixed at each high and low end, an axis in polished stainless steel secured to the profile using a screw of the same material. These are the pins which hold the uprights in the aluminum parts fixed to the sleeping frame and ensure their rotary movement allowing the release of the leaves. The tube of the largest wing serves as a housing for the rods of the closure system of each of them.

 These rods are in two parts for the external upright and in three parts for the internal upright. They are separated in their center by one or two compression springs, which keep them pushed back in the cups of the plastic parts described above. They block the uprights in the closed position.

 The third part, independent and above the rod of the interior upright, prevents, on command by electromagnetic contact, any opening operation of the interior upright. The goal is the total internal and external immobilization of all the leaves protected by the system. To release the uprights and clear the leaves, the rods must be released from the buckets in which they are pushed back. This maneuver is carried out for the internal upright, by bringing the two buttons attached to these rods and accessible from the inside and can the external upright by the hook and the part fixed to one and the ##### of the rods and accessible only after the release of the internal upright.

 At the opening, the hook and the part attached to the rods of the external upright meet to keep them outside the buckets, which facilitates the rotation of the latter and allows the sliding leaf to be released externally.

The opening of the sliding leaf internally is carried out by bringing together the accessible buttons fixed to the rods in order to obtain the identical result described above. The release of said leaf is done after rotation of the internal upright released. The intermediate uprights have yet another function, which is that of pressing the leaves against the central seal of thermal insulation so that the tightening obtained increases the tightness of the window. For easy release and maneuvering of the leaves, reverse pressure is exerted by a fine brush seal
Seal placed directly under the wing of the central seal and held in place by it. The vertical seal at closing is obtained by a self-adhesive closed cell foam seal, placed in the rebate provided for this purpose on the uprights.

 The position and the number of intermediate uprights in a sleeping frame, are a function of the number and the position of the sliding leaves. This choice is only limited by architectural requirements and necessities.

 In the case of two sliding leaves on the same rail, the vertical central junction of these is provided by a plastic profile in which is incorporated, to increase its resistance, an aluminum or steel plate as necessary.

The cross-shaped profile is composed of a vertical central tube, rectangular in shape with, on each side, horizontally back to back, two ribs taking the shape of a U.

 The profile is fixed to one of the leaves by embedding on one side of this leaf in one of the ribs of the profile. It is held in place by screwing in the upper and lower brackets for assembling this frame. The second leaf in the closed position is fitted for sealing, in the second rib of the profile fixed to the first leaf.

 The sliding leaves are designed to offer good thermal insulation at a lower price. It is to obtain this result that the unique framing profile of the insulating glazing is made of plastic, PVC type. It has the shape of a U with a tubular part receiving the accessories intended to make it autonomous.

The miter cut assembly is carried out with aluminum screw-on brackets, fitting at each angle into the tubular part. It fits directly on the insulating glass.

Before or after mounting, around the glazing, each profiled element of the frame receives the following accessories
In the lower cross member, install stainless steel carriages each comprising two plastic rollers mounted on needle bearings and stainless steel pins.

 In the upper cross member, installation of a micro burglar-resistant disc for the glazing, with contact piece for signal transmission to the receiver.

 On one of the vertical uprights, installation of a retractable aluminum pull handle also serving as a relay for the transmission of the neutral contact to the micro pellet.

 On the other vertical upright, installation of spring-mounted plastic stops for absorbing di latation differences between the materials used.

In the closed position, the action of the intermediate uprights has the effect of pressing the sliding leaves on the central thermal insulation joint. For this effect to be effective, on all of the leaves, the following arrangements are made
In the upper and lower cross member, installation of plastic rollers mounted on stainless steel screws.

 In the closed position, these rollers contribute by pressing on pressed stainless steel sheet parts, placed facing each other on the standing frame, to press the leaf on the central thermal insulation joint and on the brush located below.

 Finally, on the right and left uprights of the sleeping frame are press-fitted on stamped parts made of polished stainless steel sheet. These parts are intended to ensure by friction the plating of the leaf on the vertical parts of the central thermal insulation joint and on the brush located below.

 In addition to these provisions concerning the leaves, the central water and air tightness between the two large wings in the closed position is ensured at the top and bottom by plastic partitions fixed to the plastic parts incorporated in the joint. central thermal insulation.

 On these partitions are stuck closed cell seals to form a stop at the closing of the uprights and further increasing the seal.

The burglar prevention system incorporated in the window acts on the following data
When the intermediate uprights are in the closed position, each of them, after connection of the system, is in contact with the receiver located in the upper cross member of the window. It is the same for the micro pellet placed in the frame of the sliding leaves and for the electromagnet located above the interior upright. The system used uses the built-in electrical circuit to convey information. However, it can be provided with an independent circuit.

 Therefore, it has the possibility to send orders from anywhere in the building, as long as there is a power outlet allowing the use of the transmitter.

The actions are multiple and are as follows
1) - bright window closing control.

20) - Signal triggering a sound or light deterrent
when there is an attempt to break in the two panes
insulators.

30) - same signal for any attempt to break into
two intermediate amounts.

40) - Locking of the internal intermediate upright by contact
electro-magnetic, before or during the operation of this
him
The peripheral ribs of the two frames of the sleeping frame are designed to allow the adaptation of all the profiles either as standard, or obtained by folding necessary for the installation of joinery, both on new buildings and in renovations.

 The window shown from the front is made up of a sleeping frame consisting of two frames separated by a thermal insulation profile "M".

 The frames are executed with, for the lower cross member and the right and left uprights, a single profile A and for the upper cross member with a profile W supplemented by a removable "B" bead for the passage of the leaves. In the lower cross member, the elongated holes (3) are intended to evacuate the water from the outer frame and the holes (4) with backflow prevention the water from the inner frame. The miter cutting of each of the frames is carried out with crimping (14) and alignment (15) sheet metal brackets. They are joined one in front of the other by extruded plastic parts (6) fitting into the ribs provided on the external face of the profiles "A" "W" of the sleeping frame. These parts are replaced at the top cross member W by profiles for "X" self-ventilation. The thermal insulation joint M is glued between the two frames and the external seal is produced by a joint S applied with a spray gun. Before its installation, the insulation joint is assembled by gluing using the parts (54) located in the top and bottom crosspieces and with the help of the brackets (35) of the tab cuts.

 The assembly thus constructed is fixed to one of the frames by means of the screws (65) for mounting the high and low parts (54). A sealing brush "P" is placed on each side between the profile "N" of thermal insulation and the profiles A W # of the sleeping frame.

 The internal and external intermediate uprights "B" fixed to the sleeping frame by aluminum parts (5), held in place by T-screws pivot on top and bottom steel axes (2) to allow the leaves to be released. They are isolated from the frame by plastic washers (27). Each of them is equipped with rods, each element of which is a tube (55) with a nozzle at each end. These rods are placed one below the other with a central compression spring (56) for the internal upright and two compression springs (56) separated by a screw (57) for the external upright. The maneuver for releasing the internal upright is facilitated by the two buttons (1) mounted on the end pieces. The maneuver for releasing the external upright is facilitated by the hook <59) provided between the upper (56) and lower (58) parts of the rod ends of this upright. A piece (64) limits the travel of the bottom element. The upper rod of the internal upright comprises a part (55) independent of the rod itself. This part (55) can be maintained in the closed position by the electromagnet (52) located above it in order to block the opening of this amount.

The parts (54) incorporated in the thermal insulation joint are equipped as follows
- The lower part (54) receives the buckets (22), the sealing partition "R" and the self-adhesive seals (67). These buckets are fixed with sheet metal screws (23) and are intended to receive the rods of the intermediate "B" uprights. The upper part (54) also receives cups (22). The electromagnet (52) held in place by the bracket (53) and the screw of the external upright. The metal contact parts (60) of the microphones are under constant pressure from a compression spring (62). Their installation is facilitated by parts (61) slid in the ribs of the profile "W" of the sleeping frame. These parts (61) are made of plastic. They slide freely in a metal ring (63) forcibly mounted in the upper plastic part (54).

 The earth connection "G" also ensuring neutral contact is fixed to the standing frame by a blind rivet or a screw. The wires "H" I for supplying the electromagnet, the contact wire "J" for the micro pellets (38) of the glazings and the wire "K" for controlling the opening of the interior and exterior uprights, are connected to a receiver powered by the building's electrical circuit.

 The sliding leaves are identical. They include a frame with a single "F" profile made of plastic material equipped with two folded sheet metal carriages (49) with two plastic rollers (28) mounted on needle bearings (48) and pins, at the bottom cross member. ( 47) fixed by riveting in the carriages.

 In the upper crossmember, the micro chip (38) is placed in the housing with cover provided in the tubular part of the profile. Above this crosspiece, a metal part (34> is provided for the transmission of the signal to the receiver.

 In the uprights in contact with the intermediate uprights, the pull handle (39) is mounted on the axis (46) which is fixed to the plates (44) held in place by the screws (45).

By this handle, the neutral contact is conveyed to the micro pellet (38). The uprights fitting into the sleeping frame, are fitted with stops (8) mounted on a spring (9) and put in place using the cages (10) screwed into the profile "F"
The rollers (53) mounted on the axes (51) are placed in the top and bottom crosspieces at regular intervals.
