Description

The present invention relates to the amounts for closure frames, in particular for doors, windows, French windows or the like, separating a sheltered environment from the sun, such as the interior of a dwelling, an outside environment subjected to the rays of the sun, and in particular the constituent amounts of frames which consist of profiles generally aluminum, plastic or the like which are known to have a relatively large coefficient of expansion. By "frame" in the sense of the present invention is meant both a closing frame of a bay itself, a sliding frame opening and / or sleeping according to the terminology of the skilled person.

In the traditional solutions amounts known at present, a section constituting an amount for the so-called "opening" part of a window, French window or the like consists of two half profiles assembled by means of two insulated crimped bars. Under the effect of a significant difference in temperature between the inside and the outside, ie on both sides of the closure, and especially the sunshine, the outer half-profile expands much more that the half inner profile and, as the two elements are secured by the crimped bars, the two half profiles bend over their length. The bending of these half profiles has the effect of several disadvantages, the most troublesome is to prevent the closing of the window.

To solve this problem, achievements have been made, such as those described in FR-A-2,861,764 , 2,862,695 and 2,863,299 .

If these solutions give good results, they result particularly in practice respectively on a specific section thermal break designed to address the problem of differential expansion by a solution in the section itself and for it.

Also, the main object of the present invention is to overcome this disadvantage and to offer a closure frame amount, in particular for a door, window, French window or the like, which has the advantages of the amounts described in the documents identified. above, while proposing a global solution with a very simple structure and therefore inexpensive.

More specifically, the subject of the present invention is an amount for a closure frame, in particular for a door, window, French window or the like, characterized in that it comprises:

• a spar having a longitudinal axis substantially parallel to a first given direction,
• a shield plate defined by an oblong body whose width of a relatively small value is much smaller than the length,

• one of the first or second connecting means has a degree of freedom in translation along said first given direction and is substantially blocked in a second direction substantially perpendicular to the first given direction.

The structure defined above makes it possible to obtain a thermal break amount comprising a device for greatly reducing or even eliminating the effects of the difference in longitudinal expansion between the outer portion of the amount constituted by the shield plate subjected for example to the sunshine and the inner portion of the amount consisting of the spar which, for its part, is not, and comprising a means constituted by a portion of the shield plate forming the outer lateral edge of a groove defined by the shaped upright H, able to protect from solar radiation an associated profile, for example a complementary profile intended to be placed in said groove, avoiding the latter to be subjected to solar radiation and therefore to differential expansions between the outside and the outside. inside of it. By way of example, the amount according to the invention may comprise a lateral amount frame sliding frame and the amount of a sliding leaf, or two amounts of sliding sashes able to come into contact with one another.

According to an advantageous characteristic, said spacer is constituted by a substantially U-shaped part.

• les seconds moyens de liaison entre l'entretoise et la plaque bouclier présentent un degré de liberté en translation suivant ladite première direction donnée et sont sensiblement bloqués suivant une deuxième direction sensiblement perpendiculaire à la première direction donnée, et
• les seconds moyens de liaison étant constitués par des moyens de glissière agencés pour un glissement suivant ladite première direction donnée.

According to an advantageous characteristic:

• the second connecting means between the spacer and the shield plate have a degree of freedom in translation along said first given direction and are substantially locked in a second direction substantially perpendicular to the first given direction, and
• the second connecting means being constituted by slide means arranged for sliding along said first given direction.

It is preferable that the link with a degree of freedom in translation is made between the shield and the spacer in order to obtain maximum efficiency of the amount according to the invention with regard to the effects of the differential expansion.

According to an advantageous characteristic, the slideway means are constituted by two complementary elements able to fit slidingly into each other along said first given direction.

According to an advantageous characteristic, the slideway means consist of two hermaphrodite complementary elements.

According to an advantageous characteristic, the amount according to the invention comprises means for applying an elastic force between the two said slide elements in a third direction substantially perpendicular to the first and second directions.

This feature makes it possible to catch up with assembly games.

According to an advantageous characteristic, when the base of the U-shaped part defines the second side of the spacer, the spacer comprises at least one wall offset from said base, said wall offset along the portion of the shield plate defining the edge side of one of the grooves.

According to an advantageous characteristic, said spacer further comprises a connecting membrane connecting the two side walls of the U-shaped piece, said connecting membrane having at least one fold to give it an elastic deformation.

This feature facilitates assembly by crimping the spacer on the spar, and / or reduce the accuracy of certain assembly dimensions of these elements, and therefore the cost.

This characteristic proposes a global solution to the problem of differential expansion for an amount comprising two associated elements.

According to an advantageous characteristic, said complementary profile consists of an insulating material.

The shield plate protects the complementary profile when it is placed in the groove of the H-pillar, solar radiation, and further hides the profile complementary to the external view. Therefore, this complementary profile may advantageously consist solely of an insulating material to ensure a thermal insulation function of the profile relative to the external environment, regardless of aesthetic constraints since it is invisible from the outside when he is in the groove. The shield plate provides a protective role of the complementary profile with respect to UV. The shield plate makes it possible to prevent the associated complementary profile from being subjected to the differential expansion and its consequences; thus, the complementary profile must primarily provide the function of thermal insulation and of course mechanical strength.

According to an alternative to the preceding feature, said complementary profile consists of an insulating material associated with a metallic material, said metal material being disposed on the inside of the closure, and said insulating material being disposed on the outside of the closure.

Such a characteristic makes it possible to propose an interior aesthetic of metal profile, while offering good thermal insulation. The insulating material and the metal material constituting the complementary profile can be assembled rigidly by crimping for example, because this complementary profile is not subjected to a differential expansion between its outer portion and its inner portion when in position in the amount according to the invention.

Other characteristics and advantages of the invention will appear in the course of the following description given with reference to the accompanying drawings for illustrative but not limiting purposes, in which:

• The figure 1 represents a block diagram of the amount according to the invention,
• The figure 2 represents a first example of an industrial embodiment of the amount according to the invention in accordance with the representation according to the figure 1 , and
• The figure 3 represents a second example of an industrial embodiment of the amount according to the invention, also in agreement with the representation according to the figure 1 .

It is first of all specified that, in the figures, the same references designate the same elements, whatever the figure on which they appear and whatever the form of representation of these elements. Similarly, if elements are not specifically referenced in one of the figures, their references can be easily found by referring to the other figure.

It is also stated that the figures, and more particularly the figures 2 and 3 , represent essentially two embodiments of the object according to the invention, but that there may exist other embodiments that meet the definition of this invention.

It is furthermore specified that, when, according to the definition of the invention, the object of the invention comprises "at least one" element having a given function, the embodiment described may comprise several of these elements. Conversely, if the embodiment of the object according to the invention as illustrated has several elements of identical function and if, in the description, it is not specified that the object according to this invention must obligatorily comprise a number particular of these elements, the object of the invention may be defined as comprising "at least one" of these elements.

Finally, it is clarified that where, in the present description, an expression alone defines, without any particular specific reference to it, a set of structural characteristics, these characteristics may be taken for the definition. the object of the protection requested, when technically possible, either separately or in full and / or partial combination.

By reference more particularly to the figure 1 , the amount according to the invention may constitute one of the sides of a closure frame for a door, window, French window or the like.

This amount comprises a spar 1 having a longitudinal axis 2 substantially parallel to a first given direction 3, a shield plate 4 defined by an oblong body whose width 5 is of a relatively small value and significantly smaller than the length 6, a spacer 7, first means 8 for binding a first side 9 of the spacer and the spar 1, and second means 10 for linking a second side 11 of the spacer opposite the first 9 and the shield plate 4.

These first and second connecting means 8, 10 are respectively arranged with the spar 1 and the shield plate 4 so that the length 6 of the shield plate 4 is substantially parallel to the longitudinal axis 2 of the spar 1 and that, when they are connected, the three elements, "spar, spacer and shield plate" form a substantially H-shaped assembly defining two opposite grooves 12, 13 whose bottoms 14, 15 are essentially defined by the spacer 7 and the internal lateral edges respectively by parts of the spar 1 and the shield plate 4.

According to a preferred feature of the invention, the second connecting means 10 between the spacer 7 and the shield plate 4 have a degree of freedom in translation along the first given direction 3 and are substantially locked in a second direction 23 substantially perpendicular to this first direction given 3.

It should be assumed that the amount according to the invention is mounted so that the shield plate 4 is located in the external ambient environment. It is therefore able to receive solar radiation and likely to expand.

Due to its structure, in particular because the shield plate 4 has a large length that can reach for example three meters and a relatively small width, for example of the order of four to fifteen centimeters, the linear expansion of this shield plate is going to essentially on its length, the dilation along the width, even if it exists, may be neglected or negligible and is largely offset by the inevitable mechanical games that exist, in particular, in the slides as will be described below in a preferred embodiment of the second connecting means 10 defined above.

Under these conditions, when the shield plate receives solar radiation, it will heat shield and prevent this radiation falls on the spacer and the spar. This shield plate 4 will therefore warm up and expand essentially along its length.

But, by its mounting, the linear expansion of the shield plate 4 along its length 6 parallel to the first direction 3 will easily be absorbed by its connecting means 10 with the spacer 7, which are able to translate according to this first direction 3. The expansion of the shield plate 4 does not exert, on the spacer, deformation efforts. In addition, since the spacer is protected from radiation, it will not undergo significant heating and will not deform significantly, avoiding the drawback mentioned in the preamble of this description.

In this way, the shield plate 4 can be made of a material having a high coefficient of expansion, and thus be a good radiator to evacuate the calories it has captured under the effect of solar radiation.

The structure of the amount according to the invention described above has the result of avoiding the thermal bending of the profiles, mainly but not only the amounts of the opening of sliding or the like, due to a differential expansion between the inner portion of the amount and the external part of the amount subject to a temperature difference sometimes significant, especially during sunshine.

It is specified that an amount according to the invention preferably constitutes a vertical amount of a sliding leaf, in particular that which comprises lock means or the like, but that it can also constitute any other amount, even of a frame, whether vertical or not.

The figure 2 represents an industrial embodiment of an amount in accordance with the scheme according to the figure 1 .

According to this embodiment, the spacer 7 is constituted, to obtain a better rigidity of the upright in its entirety, by a substantially U-shaped part or the like.

According to a preferred embodiment, the second connecting means 10 defined above are constituted by slide means 30 arranged for sliding in the first given direction 3. These slide means 30 are advantageously constituted by two complementary elements capable of slidingly fitting one into the other in the first given direction and for good cooperation between the two elements in order to avoid vibrations as much as possible and to minimize the mechanical clearance between it is preferable that the slide means 30 consist of two complementary hermaphrodite elements.

Such a slide is well known in itself to those skilled in the art. It will not be more fully described here for the sole purpose of simplifying the present description. It will be simply stated that, despite many possibilities of realization, it will be advantageously realized as illustrated on the figure 2 .

For the same purpose as mentioned above to reduce vibrations or the like which are due to the inevitable mechanical play that exists in such a slide 30, it is advantageous that the amount further comprises means 50 schematically illustrated on the figure 1 , for applying an elastic force between the two slide elements in a third direction substantially perpendicular to the first and second directions 3, 23.

As illustrated on the figure 2 these elastic means 50 are constituted by a pair of opposite tongues 51, 52, having a spring effect, which are advantageously made in one piece with one of the two elements of the slide.

In addition, according to the industrial realization illustrated on the figure 2 when the base 60 of the U-shaped part defines the second side 11 of the spacer 7, the spacer 7 further comprises at least one wall 61 offset from this base. This offset wall 61 runs at least partially, and advantageously in all, the part of the shield plate 4 defining the lateral edge of one of the grooves 12 and separates the inside of this groove and the slide element integral with the shield plate.

As illustrated on the figure 2 this offset wall 61 may be integrated to form one piece with the other slide element which is secured to the second side 11 of the spacer 7.

The first means 8 for binding a first side 9 of the spacer 7 and the spar 1 are preferably constituted by crimping means.

In order to promote crimping 8 between the first side 9 of the spacer 7 and the spar 1, it is preferable that, when it consists of a U-shaped part, the spacer 7 also comprises at least one connecting membrane 40 that connects the two side walls 41, 42 of the U-shaped part are solidly integral, this connecting membrane 40 having at least one fold 43 to advantageously give it an elastic deformation, which allows the two lateral walls 41, 42 of the U-shaped piece to be perfectly pressed against a wall of the necessary orifices in the spar 1 to perform crimping 8.

It is emphasized that it is advantageous to provide stop means at both ends of the slideway means to prevent the shield plate from being detached from the spacer 7 and that, when in the vertical position, it does not fall down. On the ground.

Preferably, the spacer 7 is made of a profile made of an insulating material.

To obtain a good rigidity of the upright, it is furthermore preferable for the spar 1 to be of cylindrical tubular shape, as shown in FIG. figure 2 .

In a manner known per se, the groove 12 limited by the offset wall 61 constitutes the rabbet required for the assembly of a glazing 18 via a seal 19, the glazing resting on the offset wall 61 via the seal 19, which prevents it is in contact with the slide element secured to the shield plate.

As for the groove 13, it is adapted to receive a complementary amount 100 which is associated for example a glazing 20 mounted by means of a seal 21, this complementary amount 100 being arranged so that, when introduced into the groove 13, it is not in contact with the shield plate portion 4 delimiting this groove 13.

This complementary amount 100 may be that of another sliding or that of a frame. It will therefore also be protected from solar radiation by the shield plate 4 and hidden from an outside view by the latter, and will not undergo deformation by significant thermal expansion. As shown on the figure 2 the complementary profile 100 consists of a single material, a material advantageously insulating to impart a thermal insulation function to this profile, for example in a known manner a polyamide, preferably loaded with fibers, in particular fiberglass, or again a PVC in this case of a profile integrally made of insulating material.

The spacer 7 and the complementary amount 100 facing each other not undergoing deformation by thermal expansion, the lock means (not shown) respectively integrated in these last two elements will be able to cooperate perfectly.

• un profilé intérieur 201 en matériau métallique,
• un profilé extérieur 202 en matériau isolant, avantageusement serti sur le profilé intérieur 201. Le matériau isolant du profilé extérieur 202 sera de préférence un polyamide chargé en fibres, notamment en fibres de verre.

The example of figure 3 differs from the example of the figure 2 only with regard to the complementary section 100 which is replaced in the example of the figure 3 by a complementary profile 200, which can in particular adopt the same transverse outer section but consisting of two different materials, namely as shown in FIG. figure 3 :

• an inner profile 201 made of metallic material,
• an outer profile 202 of insulating material, advantageously crimped onto the inner profile 201. The insulating material of the outer profile 202 is preferably a polyamide filled with fibers, especially fiberglass.

The profiles 201 and 202 can adopt any suitable shapes as needed, and as shown in the figure 3 , the portion of the outer profile 202 crimped on the inner profile 201 may be made similarly to the portion of the spacer 7 described above, crimped on the spar 1, or having a connecting membrane 40 having at least one fold 43 .
