The aluminum section is composed of two sections (2,4) connected along their length by a thermal insulating material. There is a pair of runners (11,12) for receiving anchoring parts of different widths (L1,L2). One runner receives the anchoring part of a split hinge and the other a fastening bolt. The two sections comprise a pair of closed web grooves (8) which receive a semi rigid material insulating strip (6,7).

Description

their. The present invention is in the field of building finishing,

  more particularly doorframes, and its object is an element

  composite profile for window frames, of the aluminum joinery type.

  We recall that we tried, in the "aluminum" joinery and because of the high thermal conductivity of this material, to avoid thermal poets between the external and internal faces of the frame, made up of two parts, one external the other internal, the profiles which constitute the frames of the openings as well as those of the frames, and to connect these two parts together over their entire length, by a third part made of a material with low thermal conductivity, and constitute thus a composite profile but

  monobloc suitable for insulating the interior from the exterior.

  It is to this kind of elements for frames that the present invention is intended which aims to further improve the insulating properties. It should however be noted that cores and already that the material "aluminum" is not determining of the kind but only serves to locate it in a crate of products or

  of semi-finished products rather characterized by their method of implementation.

  A first drawback of the prior art referred to lies in the fact that the profiles of the genre, currently available on the market, do not allow the use of standardized accessories such as handles and their o hooks and hinges for articulation. opening it on the frame; in other words, and due to the symmetry of the accessory engagement grooves, one is forced to use special accessories. Another disadvantage of the precise prior art lies in the fact that it no longer meets the high requirements of current standards in terms of insulation, due to the z thermal transfers by convection authorized by the uniqueness of the space, in low space. but real, between the frame of the frame and that of the sash in position

closing.

  A global object of the invention is to provide an element for aluminum door frames which can enter into the constitution o of the two leaves of the frame, if it is a frame with two leaves, as well that in the constitution of the frame of the frame, while allowing the use of standardized accessories of the trade and while ensuring to the door frame its compatibility with the current standards disolation. A difficulty that had to overcome the invention in the design of such an element, was to satisfy both all

these requirements.

  According to the present invention, a composite element intended to constitute window frames of the "aluminum" joinery type, composed of two aluminum profiles connected to each other over their length by a rigid non-metallic insulating material forming a thermal barrier, the frame of the opening at least comprising ie along its periphery, a pair of slides for anchoring accessories, is mainly characterized in that the slide rails intended to receive the wind anchoring members of different widths (L1 and L2), I 'one of a standard width suitable for receiving a standard hinge anchor hinge anchoring member, the other a standard locking latch anchoring member, from which it follows that the same element can be used to constitute, by inversion , a second sash frame, in the case of a frame with two sashes, According to secondary characteristics of the invention, the first and the second component profile, along faces perpendicular to the face supporting the slides and intended to be opposite one another on either side of the median plane of the frame, each a padre of throats with "closed" wings intended to receive in correspondence a bar of said rigid material , the padre of the bars connecting the first and the second profile to form the said composite element; advantageously, in the pad of bars, the bar adjacent to the faces supporting the slides, comprises a protruding lip with a bulged edge intended according to the use case either to support a flexible and elastic seal, or to serve as a seat for a stop analogous joint of the opposing frame. It follows from these provisions that the space between the frames when the door is closed on the frame, is compartmentalized by the second seal, in two parts, one internal the other external, and it ultimately results that the temperature of one of the frames cannot be transmitted to the other frame through the air present between the two frames The present invention will be better understood and

  details will appear in the description which will be made of the profile property

  composite, but which can be defined as a composite profile, in a preferred embodiment, in relation to the figures of the appended plates, in which: fig.1 is a schematic section of a composite profile typical of the prior art ; fig. 2 is a cross section of a composite profile element according to the invention; fig.3 is a sectional illustration of the profile of the previous figure, used to form a simple opening frame, fig.4 is a section similar to that of the previous figure o in which the profile of the invention also the frame of the frame, and figs.5a, 5b, 5c and 5d, illustrate the use of such

  profile in a frame with two doors.

  In fig.1 a composite profile element of the prior art intended to constitute frames of frames, as well as frames and doors, is made up of two elementary profiles a and b and a bar 1'c made of a rigid insulating material such as PVC connecting to each other the two elementary profiles to form the one-piece composite profile; each of the profiles 1'a, 1'b comprises a slide 1'd identical to that of the elementary profile o neighbor; the two elementary profiles would be identical if one of them (1'b) was not extended by a glazing bead 1'f. This composite profile is reversible in the sense that it can be used for each of the openings in the case of a frame with two openings, in this case the glazing bead is located on the outside on one of the openings, and on the side inside on the other; note that the composite profile can also 2 constitute a frame, with glazing bead on the outside; we also note that the width of the profile, of the grip l of its wings determining for example

  the spacing of a double glazing, is determined by the width of the strip.

  In fig.2, the composite profile 1 of the invention is made up of two profiles 2 and 4 assembled together by a pair of bars 6,7, and forms a monobloc profile. In the current state of the art, the advantageous material constituting the profiles 2 and 4 is aluminum, and the material constituting the bars is PVC or better still a hard structural polyurethane; but it should be understood that the scope of the invention is not limited to such materials; One 4

  of the two profiles is extended in the usual way by a glazing bead 5.

  Each of the two profiles 2 and 4 comprises on a peripheral cited side a slide, respectively 11, 12 of different respective width L1 and L2; the slide 12 is the widest and is supported by the profile

4 which includes the glazing bead 5.

  In the preferred embodiment, the widths of the runners wind L1 = 18 mm and L2 = 20 mm, which have standardized widths

  for accessories anchors such as hinges and closures.

  Each of the profiles 2 and 4 comprises, along an inner side face such as 10, a pad of grooves such as 8 with closed wings intended to receive a bulged edge of a bar. These grooves house the enlarged edges of the bars 6 and 7 respectively. Advantageously, the bars 6,7 of the couple have a roughly V-shaped profile giving the space between them and the two profiles a substantially hexagonal section capable of withstanding well the deformation forces. It is also noted in the figure that the longitudinal median planes of the slides 11 and 12, respectively median planes P1 and P2, wind parallel, offset and distant from each other by a distance D. this

  distance is about half the average width of the slides, 9-10 mm.

  The purpose of the offset is to allow the pivoting in opening or closing of the frame, as well opening frame as frame of frame when it moves from a

casement frames.

  It is further noted in this same figure that one (7) of the bars, namely that close to the faces supporting the slides, includes a protuberance, or lip, 14 provided with a bulged edge, which is intended either to support a seal not visible in the figure, either to serve as a stop seat for a

  similar joint of an opposing frame (see following figure).

  Finally, we note in fig.2 that each of the profiles 2 and 4 includes a rectangular space 13 intended to receive a "square" of assembly (see fig.3d), including two adjacent dimensions 13a, 13b wind opposite the

  slides 11 and 12 respectively, and grooves 8.

  In fig.3, a sash frame 20 is shown closed in a frame 21 frame, one and the other window for example. The frame 20 consists of a composite element as shown in the previous figure, and of components which are assigned the same reference numbers. The frame 21 is a frame which does not come from the invention, but which calls upon elements which come under it, namely a bar 23 provided with a prominent lip 24, and, supported by the lip, a flexible and elastic joint 25 having an enlarged base including a groove intended to be taken on the lip 24 of

  one of the bars, giving it a characteristic "giraffe" shape.

  o This joint follows the internal periphery of the frame, and it appears well how it rests on the opposing lip 24 ′ arranged in a similar fashion along the internal periphery of the opening. We find these provisions on the figure of the following plates. Finally, in FIG. 3, the anchoring members 30 and 31 of a hinge 32, as well as the locking member 33 of a

  handle closure mechanism 34.

  In fig.4 we find the same arrangement as in the previous figure except that the profiles of the frame frame (21, fig.3, not within the invention) have been replaced by profiles 42 and 44 identical to the profiles 2 and 4 constituting the opening and pertaining to the invention. A flexible joint 25 ′ with an enlarged base, similar to the joint 25 of the preceding figure, is taken on and is supported by the protruding lip of the bar 7 connecting the profiles 42, 44. Finally we can imagine that a partition element could be housed in the socket 46 of the

  wings of these two profiles forming the frame of the frame.

  In fig. 5a to 5d which respectively show a partial plan view z of the adjacent corners of the frames of two leaves, and the sectional and end views of the frames, we first notice the compartmentalization in two spaces 25 and 26 of the peripheral space between the frame frame, similar to the frame 21 of fig.3, and the frames of the opening, and in two spaces 25 'and 26' of the space between the uprights of the opening frames. This compartmentalization helps to avoid heat transfers between the exterior and the interior. Secondly, we also notice in fig.5d that if the frame 41a is. as represents that of an opening one can imagine that the frame 41b could just as easily be that of a frame, which would extend to the top of the opening to be extended, by a miter cut, above, at below and all around the frame of the opening 41a. Finally, we notice in fig.5a squares such as 45 logGes in the rectangular spaces 13 of the profiles. The drawings of the figures can be used for the execution and thus provide the person skilled in the art with all the technology useful for implementing the invention. It should however be understood that the scope of the invention is not limited to this form of execution, but that it extends to any mono-material or composite profile, comprising general or particular characteristics, whatever the nature of the materials known in the art

or which would come to be created.
