Description

METALLIC CHASSIS SUCH AS ALUMINUM CHASSIS,
FOR OPENINGS, LEAVES EQUIPPED WITH SUCH CHASSIS
AND PROFILE USED FOR THE REALIZATION OF THESE LEAVES.

 The invention relates to a metal frame, such as an aluminum frame, for openings. It extends to the leaves fitted to such frames and to the profiles used for the production of these leaves.

 At present, there are mainly two families of aluminum chassis.

 The first family consists of frames comprising on the one hand a frame of a standing frame, and on the other hand a leaf frame composed of sections assembled at an angle, by means of pawl or crimped brackets, and glazing beads coming s snap onto said profiles. In addition, the leaves are sealed by means of a heel joint immobilized in a groove of the profiles and a stuffing joint interposed between the glazing and the glazing beads. The disadvantage of this type of frame lies in the fact that, by design, it does not allow the use of glazing bordered by a wallet seal which has the advantage of being able to be fitted into the sleepers and uprights simultaneously to the assembly of these. Therefore, the time required to produce a leaf is very long because it requires assembling the uprights and crosspieces, putting in place the heel joint, positioning the glazing, cutting the glazing beads, snapping them together on the profiles, and finally to set up the joint to be stuffed. Given the number of stages necessary for the manufacture of the leaves, and the impossibility of industrializing this manufacture, the major drawback of such frames thus lies in their relatively high cost price.

 The second family of frames comprises a frame of a standing frame, and a leaf composed of profiles provided with a U-shaped rebate in which is fitted a glazing bordered by a wall joint.

The major advantage of this type of chassis compared to those of the aforementioned type lies in the fact that the manufacturing time is significantly reduced (replacement of the heel seal and the seal to be stuffed with a simple wallet seal, removal of glazing beads. .). However, it has a disadvantage compared to the frames of the first family when it comes to replacing the glazing of a frame in place. This operation poses, in fact, no difficulty for the chassis of the first family because it suffices to remove the glazing beads, install new glazing, re-snap the glazing beads and install a new seal to stuff. On the other hand, the replacement of a glazing is made difficult, even impossible, for the frames of the second family. Indeed, this replacement requires disassembling the uprights and cross members of the leaves. However, if this operation is possible when the latter are assembled by means of dismountable brackets (with pins, pins, etc.), it remains uncertain as to the tightness of the reconstructed leaf because the reassembly operations on site are carried out so less precise and meticulous than in the factory. In addition, this operation becomes impossible when the uprights and crosspieces are assembled with crimping brackets. However, it should be noted that such crimping brackets have a significant advantage over dismountable brackets during the manufacture of the chassis because they reduce the number of steps required for this manufacture (elimination of the need to drill the profiles , the pawns engagement operation ...).

 Consequently, such frames either make it possible to optimize the manufacturing time but then prohibit any replacement of glazing, or allow the glazing to be replaced, under however difficult conditions and without any guarantee on the quality of the seal obtained, but at detriment of the cost price during manufacture.

 The present invention aims to overcome these drawbacks and proposes to provide a metal frame, on the one hand, the cost price can be optimized thanks to reduced manufacturing times and the possibility of industrialized manufacturing, and other part, allowing an easy and safe change of glazing.

 Another object of the invention is to provide a chassis with thermal break when the latter is of the "hidden leaf" type.

 Another objective of the invention is to provide a frame whose wallet seal is reusable during a change of glazing.

 Another objective of the invention is to provide a frame making it possible to modify the thickness of the glazing when replacing the latter.

 To this end, the invention relates to a metal frame, such as an aluminum frame, for openings, comprising a standing frame composed of uprights and crosspieces assembled at an angle, and at least one leaf composed of uprights and crosspieces assembled at an angle, and a glazing bordered peripherally by a wallet seal between said glazing and said uprights and crosspieces.

According to the invention, this frame is characterized in that the crosspieces and uprights of each leaf comprise
a profile comprising a longitudinal rebate having the shape of a square having a so-called vertical wing arranged to extend parallel to the plane of the glazing and a so-called horizontal wing arranged to extend orthogonally to said plane of glazing,
a glazing bead comprising a wing arranged to extend parallel with respect to the plane of the glazing so as to form a groove of width suitable for sealingly housing the wallet seal, with the rebate of the profile,
said profile and glazing bead having
- complementary nesting structures arranged towards the end of the horizontal wing of the profile and towards one of the ends of the wing of the glazing bead, and arranged to cooperate in order to allow the said glazing bead to be brought into a position called d '' assembly where the wing thereof extends parallel to the vertical wing of the profile and forms with the latter the housing groove of the portfolio seal,
- Snap-fastening means capable of removably locking the profile and the glazing bead in the aforementioned assembly position where the latter form a housing for the wallet seal.

 The frame of each leaf of a frame according to the invention therefore consists of uprights and crosspieces composed of a profile and a glazing bead which, once assembled, on the one hand, give these uprights and crosspieces the rigidity profile in one piece, and secondly, allow disassembly by simple release.

 Consequently, the manufacturing times can be optimized because all the operations are carried out once the profiles and glazing beads are assembled, that is to say as if the sleepers and uprights were in one piece (cuts to the desired length, drilling drainage holes ...). In addition, the glazing with its portfolio seal fits into the uprights and crosspieces simultaneously with the assembly of the latter, and this assembly can be carried out with crimping brackets.

 In addition, any glazing changes simply require unlocking the latching means and removing the glazing beads, the replacement then being carried out conventionally.

 Furthermore, when the standing frame is of a shape suitable for hiding the uprights and leaf crosspieces and comprises at least one thermal cut-off element, the glazing beads can advantageously be made of a material capable of ensuring a heat shield, thus providing a frame for thermal break.

 According to another characteristic of the invention, the interlocking structures form a ball joint arranged to allow relative pivoting of the profile and glazing bead around a longitudinal axis, the latching means being arranged to be stressed when said profile and glazing bead are brought by pivoting in their assembly position.

 The assembly is thus carried out by presenting the glazing bead in an inclined manner and by pivoting it by cooperation of the interlocking structures until the locking means are locked.

 In addition, according to a preferred embodiment, the interlocking structures include a longitudinal groove formed laterally below the horizontal wing of the profile, and a blocking head of rounded shape adapted to be housed and able to pivot in the groove. , arranged towards the end of a fin extending orthogonally relative to the wing of the glazing bead.

 Such an arrangement makes it possible to produce in a simple manner a chute for recovering the infiltration water constituted by the fin of the glazing bead, which is offset downward relative to the horizontal wing of the profile.

According to another characteristic of the invention, the latching means comprise
a locking heel having a concave upper face, formed towards the end of a fin extending orthogonally relative to the fin of the glazing bead, substantially set back from the locking head, and giving said glazing bead the general shape one hour,
a longitudinal groove of convex shape conjugated with the shape of the upper face of the locking heel, formed below the end of an L-shaped fin, extending orthogonally under the horizontal aid of the profile, substantially in removal of the lateral end of the latter.

 In addition, the fin of the glazing bead carrying the locking heel advantageously comprises two longitudinal bosses of rounded shape offset so as to form two steps, the boss closest to the locking heel being disposed at a distance from the latter adapted to allow pinching the end of the profile fin between said boss and heel.

 The presence of these bosses on the one hand makes it possible to perfect the locking by pinching of the end of the fin of the profile, and on the other hand, thanks to their rounded shape, facilitates the escape of the glazing bead when this- this is requested with a view to its withdrawal.

 Furthermore, the portfolio seal advantageously comprises lines of least resistance at the connection between the core and each wing of said seal, capable of making it possible to separate each of said wings from said core. Such a seal offers the advantage of being able to be reused after being cut during a change of glazing, each of the wings then being arranged opposite one face of said glazing.

 In addition, according to an advantageous embodiment, the vertical wing of the profile and the wing of the glazing bead are provided with seal carrier grooves formed towards the free end of said wings. Such grooves make it possible to replace glazing with glazing of different thickness, a situation in which the cut wallet seal cannot be reused.

 The invention extends to a leaf for a metal frame whose uprights and crosspieces combine the abovementioned characteristics as well as to a profile fitted to such a leaf.

Other characteristics, objects and advantages of the invention will emerge from the detailed description which follows, with reference to the appended drawings which represent, by way of non-limiting example, a preferred embodiment. On these drawings which form an integral part of the present description
FIG. 1 is a cross-sectional view of a chassis according to the invention,
FIG. 2 is a cross-sectional view, on an enlarged scale, of the constituent elements of a frame leaf according to the invention,
FIGS. 3a to 3c are diagrams, in cross section, illustrating the assembly of a glazing bead and a leaf profile,
- And Figures 3d to 3f are diagrams, in cross section, illustrating the steps necessary for a change of glazing.

 (For the sake of simplification, the chassis will be described by considering the elements as constituting the lower cross member of the fixed frame and the leaf, the terms vertical, horizontal, upper, lower, lower, upper, etc. referring to such a cross member. low, it being understood that the high uprights and crosspieces of a chassis according to the invention consist of similar elements).

 The chassis element shown in FIG. 1 is of the thermal break type known as a "hidden opening", that is to say that, seen from the outside, the sleepers and uprights of the standing frame mask the sleepers and uprights of each leaf.

 This chassis element comprises a profile 1 of a standing frame, a leaf element consisting of a profile 2, a glazing bead 3, and a glazing bordered by a wallet seal 5, and "Neoprene" seals 6, 7, 8 interposed between said profiles 1 of the frame and leaf element.

 Firstly, the section 1 of the standing frame is a conventional section for chassis of the so-called "hidden sash" type. It has a section with the general shape of an L (shown inverted in Figure 1).

 The horizontal wing of this profile 1 is divided into two tubular profiles 9, 10 connected by two horizontal bars 11, 12 of thermal break, the profile 10 adjoining the vertical wing 13 being surmounted by an inclined fin 14 of stop of one of the "Neoprene" seals 7 mounted on the leaf.

The vertical wing 13, for its part, mainly consists of a tubular profile in the form of
V with a vertical lower section and an upper section inclined towards the leaf.

 The profile 2 defines, for its part, the rabbet for receiving the glazing 4. This profile 2 comprises, first of all, a tubular core 15, one of the vertical sides 16 of which defines the vertical wing of the rabbet.

This vertical wing 16 is, moreover, provided, towards its upper end, with a groove 17 in the heel seal holder, and has, over a portion of its height, horizontal grooves 18 for blocking the wallet seal 5.

 The side of the tubular core 15 opposite the vertical wing 16, is, in turn, extended downwards from a vertical wing 19 provided at its lower end with a groove 20 seal carrier housing the heel of one of the "Neoprene" seals 8 arranged to abut against the tubular profile 9 of the profile 1.

 The second wing of the rebate is, for its part, constituted by a horizontal wing 21 extending orthogonally relative to the vertical wing 16, at a distance from the lower end of the latter. This horizontal wing 21 is further extended, at its free end, with a vertical flange 22 oriented downwards.

 The profile 2 further comprises an L-shaped fin 23 whose vertical branch 23a extends orthogonally under the horizontal wing 21 at a distance from the flange 22 adapted to form a groove with the latter. The horizontal branch 23b of this fin 23 has, for its part, a groove 24 of rounded shape formed under the face of the end of said branch.

 In addition, this fin 23 is connected to the tubular core 15, at the lower end of its vertical branch 23a, by means of a horizontal branch 25 delimiting with said vertical branch, the tubular core 15, and the horizontal wing 21 of the rebate, a profile of rectangular section.

 Finally, the fin 23 carries a groove 26 seal carrier extending under its horizontal branch 23b and housing one of the "Neoprene" seals 7 arranged to come into abutment against the fin 14 of the profile 1.

 The glazing bead 3 has, in turn, the shape of an h (shown inverted in the figures), and consists of a vertical wing 27, and a foot 28 in the form of a square.

 The horizontal fin 28a of this foot 28 is extended by a blocking head 29 of generally rounded shape capable of being received in the groove delimited by the rim 22 and the vertical branch 23a of the fin 23, and pivoting in the latter. This locking head 29 has, in addition, opposite the wing 27 of the glazing bead 3, a flat 29a adapted to come to press against the internal face of the rim 22 in the position of said glazing bead where the latter is locked with profile 1.

 The second fin 28b of the foot 28 of the glazing bead comprises, for its part, at its lower end, a locking heel 30 of section conjugate with that of the groove 24 adapted to snap into place in said groove.

 This second fin 28b also has two longitudinal bosses 31, 32 of rounded shape, offset with respect to each other so as to form two steps between the locking head 29 and the locking heel 30. In addition , the lower boss 32 is disposed at a distance from the locking heel adapted to pinch the end of the fin 23 between said boss and heel when the latter is housed in the groove 24.

 Finally, the wing 27 of the glazing bead 3 has a groove 33 in the form of a notch formed towards its upper end, and intended to maintain a seal to be stuffed. In addition, this wing 27 has, over a portion of its height, horizontal grooves 34 for blocking the wallet seal 5.

 This wallet seal 5 has, in turn, in a conventional manner, a U-shaped section adapted to come over the edge of the glazing 4. This seal 5 further comprises, at the end of each of its wings 5a , a support lip 35 on the glazing. It also has longitudinal ridges 36 formed over a portion of the height of the wings 5a and adapted to cooperate with the ridges 18, 34 of the profile 2 and the glazing bead 3.

 This wallet seal 5 finally comprises lines 37 of least resistance at the junction between the core 5b and each of the wings 5a.

 As shown in Figures 3a to 3c, the assembly of the profile 2 and the glazing bead 3 is produced by presenting said glazing bead inclined relative to said profile, so as to bring in cooperation the interlocking structures that constitute the blocking head 29 and the groove delimited by the rim 22 and the fin 23.

 The glazing bead 3 is then pivoted until it brings the locking heel 30 inside the groove 24 and thus rigidly assemble the profile 2 and the glazing bead, this rigid support being provided both at the level of the locking head 29 and at the locking heel 30.

 Once this assembly has been carried out, all of the machining operations can be carried out as if the profile 2 / glazing bead assembly 3 was made up of a profile in one piece, and in particular the glazing 4 bordered by its portfolio seal can be fitted in force in the groove delimited by the wings 16, 27 of the profile 2 and the glazing bead 3.

 When it is necessary to change the glazing 4, disassembly of the glazing bead 3 is carried out by causing it to pivot in the opposite direction from its direction of installation, by means of a tool blade inserted between the wing 28b of the foot 28 and the wing 27.

 This pivoting causes the locking heel 30 to be withdrawn from the groove 24, the escape from the glazing bead 3 making it possible to separate it from the profile 2 then being facilitated by the presence of the bosses 31, 32.

 Once the disassembly has been carried out, the wallet seal 5 is recovered and then cut along its lines 37 of least resistance.

 The two wings 5a of the portfolio seal can then be reused as illustrated in FIGS. 3d to 3f to ensure the maintenance of the new glazing between the profile 2 and the glazing bead 3.
