Description

SPECIFICATION Prefabricated thermal or phonic, insulating glazed panel having an incorporated ventilation opening and shaped section for the construction of such a panel The invention relates to a prefabricated thermal and/or phonic, insulating glazed panel having an incorporated ventilation opening.

In operations for the reinforcement of the thermal and/or phonic insulation of glazed bays it is indispensable to have complete weatherproofing between the casing and opening frames to prevent the passage of noise and the entry of draughts. Measurements carried out in a specialized laboratory have shown that there is a gain of 7 dB(A) on a "road noise spectrum" and 10 dB(A) on a "rose noise spectrum" by merely placing silicone-moulded weatherproofing joints between the casing and the opening. Numerous processes already exist for performing this weatherproofing.

When in the case of existing closures the single sheet of glass is replaced by double or multiple insulating glazing using adaptation members like those described in French Patent Application 2 329 837 weatherproofing is systematically brought about between the casing and the opening. As a result objects equipped in this way become unhealthy because there is an inadequate air replacement.

The object of the invention is to obviate this problem by providing a novel prefabricated glazed panel, which is as simple to use as the known insulating glazed panels, but which permits a perfectly controlled ventilation. Moreover, the invention makes it possible to produce such panels in an extremely simple manner and therefore inexpensively.

The invention therefore relates to a prefabricated thermal and/or phonic, insulating glazed panel comprising a single or preferably multiple glazing, but with significant insulation properties. The entire periphery of the panel is surrounded by an adaptation member having means permitting the fixing of the panel to a conventional opening from which the previously provided glazing has been removed. According to the invention on one of its edges the panel has a shaped air replacement assembly comprising on the one hand means for receiving the corresponding edge of the glazing and on the other adaptation means on the opening.

According to a first embodiment the air replacement assembly mainly comprises a shaped section, whose thickness and width are sufficient to make it possible to position in a central cutout controlled air replacement means, the shaped section being cut to the desired length.

According to a special embodiment of the invention the shaped assembly comprising the said air replacement means has on the glazing side the same section as the glazing side section of the peripheral adaptation members and on the opening side the same section as the latter.

In this embodiment the shaped assembly consequently has on its two edges the same configuration as the adaptation members but, with respect to the latter, has a width increase making it possible to receive and house the air replacement means.

According to another embodiment of the invention the member has on its two edges a random section designed so as to receive on the glazing side a first member bordering the glazing and on the opening side a second member which can be adapted to the opening.

In this embodiment the first member has on the glazing side a section which is identical to that of the adaptation member and the second member has on the opening side a section identical to that of the adaptation member. Advantageously the first and second members can be identical to the adaptation members.

Obviously and as a variant the replacement member can be designed in accordance with one embodiment for one of its sides and according to the other embodiment for the other side. For example it can itself have the section necessary for receiving the glazing and on the opposite side can cooperate with a second member which is to be connected to the opening.

Preferably means are provided for sealing the two ends of the replacement member which can either be fixed in or onto extensions of the two lateral adaptation members which are then extended beyond the glazing, or have themselves shapes making it possible to directly or indirectly, via a short member portion, adapt them to the opening.

Thus, for example, the thickness of the replacement member can be made such that it penetrates by its ends into the extended perpendicular adaptation members or, provided that it has an adequate thickness, can receive said extensions of the adaptation members.

If applicable the panel may comprise means for the positive joining of the different members to one another, but the invention makes it possible to advantageously assemble the different parts of the panel by fitting together without positive connection means being provided. The exception being those such as glue or mastic, which join the single or multiple glazing to the members which border it.

The replacement member comprising the air replacement means can either receive conventional ventilation boxes in cutouts or can itself be shaped so as to form a ventilation box.

The replacement member is preferably made from a synthetic material and is advantageously partitioned so as to obtain a better insulation, particularly phonic insulation.

According to a second embodiment of the invention the assembly can be formed in a complex manner, e.g. using four members arranged like a frame, leaving at the centre an empty portion in which can be mounted the air replacement means, and, if necessary, means for closing the empty space.

The ventilation means may consist of known self-regulatable openings, comprising for example a flexible sheet which progressively deforms under the action of the differential pressure between the two faces of the panel and calibrating the passage of air. However, according to another embodiment these ventilation means may comprise controlled mechanical ventilation means using, for example, motors. The electrical power for the motors may either come from the outside or may be supplied by solar cells.

Various control and regulation means can then be provided for controlling the ventilation and which are constituted, for example, by presence sensors and/or carbon dioxide sensors, as well as optionally a programmable microprocessor and an associated memory store.

Reference will firstly be made to Figs. 1 to 4.

The panel comprises insulating double glazing constituted by panes 1 and 2, separated from one another in per se known manner by a spacing and sealing member 3. The lateral and lower edges of the double glazing are respectively received in vertical adaptation member 4 and horizontal adaptation member 5, having an identical crosssection. These adaptation members are described in French Patent Application 2 329 837 and have a web or base 5a with on one side two lateral wings or arms Sb, 5c and on the other side a linear extension 5d at right angles from base 5a.

Extension 5d is applied to the fillister of an opening 6 and is fixed against said fillister by fixing means such as nails or screws, the remainder of the fillister then being masticated (cf. Fig. 1). Arm 5b (cf. Fig. 4) has two pins or ribs, namely 5e at its free end and 5f closer to the base. At a certain distance from its free end arm 5c has a pin or rib Sg oriented towards pins Se, 5f, Sg projecting over arm 5b between pins 5e and 5f. At 5h it is possible to see the mastic occupying the gap between the free end of pin Sg and the glazing.

The ventilation system mainly comprises a ventilation member 7 made from a plastics material and having an internally partitioned construction. Member 7 has a substantially rectangular peripheral shape. On its upper edge it has a base 7a with a perpendicular extension 7d so that said upper side, which is oriented towards opening 6, is shaped in the same way as the opening side shape of member 5, thus permitting its adaptation to opening 6. On the other side, i.e.

on the glazing side member 7 has two wings or arms 7b, 7c, which are in all respects identical to wings or arms 5b, 5c having the same pins and receiving the glazing in the same way.

As can be seen from Fig. 2 in the intermediate partitioned part of member 7 there is a passage perpendicular to the plane of the panel in which is located a controlled ventilation box 8, whose grating 8a can be seen. In per se known manner this ventilation box 8 may have a flexible air calibration sheet which progressively deforms under the differential pressure between the two faces of the panel or can be of any other known type.

As can be seen in Fig. 2 the two vertical adaptation members 4, having the same crosssection as member 5, are extended beyond the upper end of the glazing up to the upper part of the ventilation member 7, where they end with a bevel 4a. It is also possible to see that the ventilation member 7 has been sectioned at a certain distance from each of the extensions of adaptation members 4. In order to laterally seal the two open ends of ventilation member 7 and ensure the sealing thereof two moulded connecting pieces or end fittings 9 are provided having on their face oriented towards the end of ventilation member 7 grooves 9a which cover the ends of the ribs or partitions 7e of member 7. On the other side piece 9 has a much narrower portion 9b which is able to penetrate the adaptation member 4 in which has been placed an appropriate quantity of mastic or glue.

Thus, the panel formed by glazing 1, 2, the lateral adaptation members 4, adaptation member 5, ventilation member 7 and the two end fittings 9 constitutes a one-piece rigid panel which can be manufactured in the factory, then fitted as it is to an opening 6 from which the previously existing single pane of glass has been removed.

Fig. 5 shows a ventilation member 11 replacing the ventilation member 7 of the previous drawings. Member 11 having a substantially rectangular cross-section internally has a partition identical to that of member 7. On its lower edge on the glazing side member 1 1 has two parallel wings or arms 1 a, 1 1 b, thus forming a channel with a rectangular cross-section for receiving the double glazing 1, 2 with the interposing of an appropriate quantity of mastic.

At its end and set back from the horizontal base 1 c formed by said end member 1 1 has a horizontal wing or tongue 1 d to be applied to the edge of opening 6, whilst the right angled wedge adjacent to the end of the profile is placed in the fillister of opening 6, with the interposing of an appropriate joint. Moreover, in this case members 4 and 5 of the panel are replaced by adaptation members of the type described e.g. in French Patent 2 293 561. These adaptation members generally have the shape of a U-channel with two parallel arms and, at an adequate distance from the web or base joining the two arms, an extension or tongue like 1 d. They receive the double glazing like member 11 and are fixed to opening 6 in the same way as the member.

Otherwise the arrangement can be the same as for the panels of the previous drawings. Thus, the ventilation member 1 1 conveniently provided with end parts is inserted between extensions of two vertical adaptation members or conversely the vertical adaptation members are not extended beyond the upper edge of the double glazing, so that then the end parts have a tongue such as lid.

Reference will now be made to Fig. 6. The ventilation member 12 which, in this drawing, replaces member 11 or member 7 also has a partitioned structure with wings or arms 1 2a, 1 2b identical to wings or arms 1 a, 1 b for receiving the double glazing. At its upper end the ventilation member 12 has a base 1 2c followed by a detachment 1 2d which together form a right angle fitted into fillister of opening 6. Following detachment 1 2d member 12 is continued by a further horizontal surface 1 2e which can be applied to the edge of opening 6 via e.g. a mastic layer. Studded clips may optionally be provided for cooperating with notching on the upper face of surface 1 2e. The ventilation member 12 then has an inclined upper elastic sealing arm 12f which can be fixed by nails or screws to the outside of opening 6 for sealing purposes.

Preferably the adaptation members such as 4 and 5 of the panel are then replaced by adaptation members having on one side the shape of a channel with arms such as 1 2a and 1 2b and on the other side the shape of the upper part with three surfaces such as 1 2c, 1 2d and 1 2e, as well as a sealing arm 1 2f.

Although less satisfactory it is to be understood that it is also possible to use adaptation members such as 4 and 5 with ventilation members such as 11 or 12.

According to another constructional variant of the invention shown in Figs. 7 and 8 the ventilation member 13 (Fig. 7) has a cross-section which is the same as that of member 7 (Fig. 1) and the same as the latter with respect to the upper edge on the upper opening side. However, on the glazing side 1, 2, 3 member 13 does not have arms such as 7c, 7b. Instead it has a horizontal planar base 1 3a followed by a narrow, deep groove 1 3b. This groove permits the force fitting of extension 1 4a of an adaptation member 14, whose cross-section is in all points identical to that of members 4, 5. Thus, adaptation member 14 is fixed against base 1 3a of ventilation member 13 and receives the double glazing 1, 2.

On referring to Fig. 8 it is possible to see that the adaptation members 4 are not extended on either side of ventilation member 1 3, but in fact terminate as a bevel 4b fitting exactly to the corresponding 45C bevel of the adaptation member 14. The open ends of ventilation member 13 are sealed by end pieces 10, whose portion oriented towards ventilation member 13 is identical to the corresponding portion of piece 9 with grooves 9a (cf. Fig. 3) but which, instead of having a reduced thickness portion such as 9b has an extension in the form of an arm 1 Oa with the same thickness and size as extensions 5d, 7d (cf.

Figs. 1, 2 and 4) and which is therefore arranged in the extension of the corresponding arms of adaptation members 4 and of the upper arm 1 3c of ventilation member 1 3.

Fig. 9 shows a ventilation member 15 identical to ventilation member 13 with regards to its lower edge on the glazing side and which cooperates with an adaptation member 14. However, the upper edge of ventilation member 15 on the opening side is received in an adaptation member 16 fixed to opening 6 and having exactly the same cross-section as member 14 and members 4 and 5. To this end the ventilation member 15 has a groove 1 5a receiving the pin 1 6a of adaptation member 16 and on the other side a flexible tongue 1 5b which engages on pin 1 6b of the arm of member 16, said pin 1 6b projecting over the opposite arm between pins 1 6a and 1 6c.

At its two ends ventilation member 15 can be provided with end pieces identical to pieces 9 or 10.

Reference will now be made to Figs. 10 and 1 1.

Fig. 10 shows a construction in which ventilation member 17, whose cross-section is shown at the same level as a controlled ventilation device 8 of a conventional type, has a generally rectangular shape with, in its central part, a passage permitting the fitting of the ventilation device 8'.

As shown in the drawing the width of ventilation member 17 is less than the width of adaptation member 16 located in the upper part in such a way that member 17 is accurately adjusted by its upper end to the inside of adaptation member 16 where it is held in place.

In its lower part ventilation member 17, which retains the same width, is fixed to an adaptation member 18, which is essentially identical to member 1 6, except that on the side of the base opposite to the two arms it does not have an extension like extension 1 6d. The connection between adaptation member 18 and ventilation member 17 can be brought about in any appropriate manner, e.g. by welding or glueing, or member 18 can be fixed to member 17 during manufacture in order to form therewith a single adaptation and ventilation member.

Due to the fact that ventilation member 17, which, in the longitudinal direction is extended beyond the two ends of device 8a, has a width which enables it to be introduced into an adaptation member such as 4, 5 or 1 6, its two ends can be received in members 4, provided that the latter are extended up to the level of adaptation member 16 to which they are connected by a 450 bevel.

In this construction there is no longer any need to provide end pieces such as 9 or 10, because the ventilation members 17 are sealed at their ends by the introduction of the vertical adaptation members 4 into the rectangular channels.

Reference will now be made to Figs. 11 to 13.

In this constructional embodiment the double glazing comprises two vertical adaptation members 4. In its upper part the double glazing is received in a member 19 made from a plastics material and having two arms 19a, 19b, whereof one carries a pin and the other two pins so as to form a cross-section identical to that of members 4 or member 18 at this level. Member 19 continues with a widened base 19c, provided with two borders 19d.

The ventilation system has two lateral members 20 and an upper member 21 in addition to member 19. The lateral members 20 and upper member 21 have the same cross-section shown in Fig. 12. These members comprise a base such as 20a with two borders 20b, identical respectively to base 1 9c and the two borders 19d, whilst on the other side member 20 has a base 20c, laterally provided with an extension 20d giving that part of the member a cross-section identical to that of member 4 or member 1 6.

The two members 20, member 21 and member 19 are assembled in the manner shown in Fig.11, level with their 450 part ends, by welding or any other assembly procedure, so as to form a frame having in its lower part a space 22 to be occupied by a suitable ventilation device.

The thus formed complete panel has on its periphery, including at members 20 and 21, means permitting its adaptation and fitting to an opening.

Reference will now be made to Figs. 14 and 15.

According to this presently preferred embodiment the ventilation device 23 is heightwise fitted between a horizontal adaptation member 25, identical to member 5 of Fig. 4 and constituting the top of the air replacement panel according to the invention, and a horizontal interposed member 26 at H. Adaptation member 25 has a web 25a, two arms 25b, 25c and an extension 25d, respectively identical to parts Sa, Sb, Sc and 5d of Fig. 4. Interposed member 26 comprises on either side of a web 26a two opposite arms 26b identical in each case to arm 5b or 25b and two opposite arms 26c identical in each case to arm 5c or 26c.Laterally the ventilation device 23 is fitted between two vertical members 24, identical to horizontal member 25 and connected thereto in each case by a bevel 27.

Double glazing 1, 2, 3 is surrounded by the lower channel of the interposed member 26, by most of the lateral members 24 and by a not shown lower member, identical to member 25, but reversed relative thereto. Member 26 stops against the free edge of the arms of vertical members 24. The ventilation device 23, which is not shown in detail in Figs. 1 4 and 1 S, comprises a panel 28 made from a generally opaque material (wood, veneer, plastics) or translucent material (non-transparent glass), provided with d rectangular opening 29 whose free section can be regulated by a ventilation box of the same type as box 8 in Fig. 2. The intermediate member 26 thus divides the frame formed by the two horizontal members 25 and the two vertical members 24 into an upper subframe for device 23 and a lower subframe for double glazing 1, 2, 3.

In general terms the assembly comprising the ventilation means, no matter whether it is formed by a single member or by a number of members or in the manner of a frame, can advantageously have a height of about 10 centimetres. This enables it to easily receive the ventilation means, generally constituted by a strip of height of 7.5 cm, length 25 to 50 cm and thickness generally 3.5 cm.

Although the invention has been described relative to specific embodiments it is in no way limited thereto and various modifications of shape and material can be made thereto.

Thus, it is in particular possible to modify the cross-section of the adaptation members, as well as the corresponding parts of the ventilation system section. Thus, other adaptation member sections can be used, both with regards to the reception and maintenance of the glazing and with regards to the adaptation or fitting to the opening.

It is also possible to fit the panel according to the invention to the opening by clipping to an auxiliary member previously nailed to the bottom of the fillister, as described e.g. in French Patent 2 293 562.
