MENIJ-SEPIE STRUCTURE ELEMENTS TRIM SYSTEM

BUILDING.

  The present invention relates to the window or window-door frames or any other structural element conventionally considered to be part of the

  field of building joinery.

  In the field of exterior joinery for the building, the frames (frames of frame or of vancouver were traditionally made out of wood or metal, until appearing the chassis in master niastique or composite, in particular in PVC, each of these

  M materials with its advantages and disadvantages.

  For aesthetic reasons, it is known to provide metal structures of light alloy such as aluminum, or plastics, with a bowl decoration on the inside. In particular, a solution of this type is known from EP-B-0454806. The frames consist of light alloy profiles assembled under the form of frames. Each profile has on the underside of the frame a longitudinal groove in oestinee to receive rotating elements. These rotating members have a disc-shaped flange which inserts and slides in the T-groove without the rotating member being able to leave the groove. It is extended by a rotation drive square, then a disk forming: laette having two parallel flats and

  symmetrical to the axis of the rotating element.

  A wooden section having a groove whose flanks are recessed is held on the frame by the rotating elements. The flats of the disk allow the key disk to fit into the groove of the wood profile. During rotation of the rotating element, the clavetle disc comes into contact with the hollow of the flanks of the groove, until a blockage of the rotary element is achieved. clamping between the flanks of the groove. The profile ern bowls once in place acts as a bead to maintain the

window in place.

  A disadvantage of this solution is that it is necessary that the metal profile has a T-slot. Such a solution is not applicable to the renovation of existing chassis. Indeed, it is hardly possible to make a T-slot on joinery already mounted. Moreover, in case of replacement of the wood profile, for a repair-tion for example, the window is no longer maintained, which makes

the delicate intervention.

  When mounting this system, the rotating elements are maintained only when they have undergone a quarter turn of blocking. Before this operation, they can slide freely in the T-slot of the metal profile. In addition, due to the serraoe between the flanks of the groove of the wooden profile, is induces in it a stress which can result in a 2 () deformation of the wooden profile or promote the appearance

of slits.

  The present invention aims to overcome these drawbacks and aims in particular to provide a building joinery frame that: * provides a connection allowing differential expansion between the frame profiles and the trim profiles, and without inducing stress in the dressing profile, * allows the easy change of this dressing and without 3 (risk of deterioration of the joinery, * allows easy adaptation on existing joinery, * ensures an aesthetic appearance, in accordance with the environment of the carpentry by the fixing of an interior lining, without apparent fastening element, * ensures a thermal insulation by the absence of these bridges -hermiques.With these objectives in view, the invention has pur ojet a system of elements dressing of carpentry of building, having habillace ents consisting of profiles of hai le, 1

  inside the building. According to the invention, it is characterized in that the form-fitting profiles consist of a T-shaped groove, the opposite flanks of the T-shaped flange comprising two tongues directed towards one another and separated. by a neck, the profiles of ethaniage etail maintained on the elements of structure because the Oots your ix: atLon distributed on the length of proi s d 'dressing, spaced one of the other, the: -its ps ti ixation including a polygonal base, a central part and a pin head, the front head a largeur less than the width of the neck, ergcts tnt engn nra: with the tabs to maintain- gold trim, said studs Fixing bolts pivoting on pivots fixed on 'C lemen- s: -I structure. The system according to the invention makes it possible to reach

  all of the above stated goals.

  Rec. Indeed, the trim profiles are min-, on the chassis of the joinery by olos iaton olos are not apparent, since they recnteats rec rears r orofilés dressing. This method allows the possibility of designing the shape, the dimensions and the appearance of the independent trim profiles and the production of the frames, depending on the desired aesthetic appearance. The materials can be chosen ecologically, for example, from wood, aluminum, or the use of T-blocks, preferably in the field of synthesizing, to imitate any effect of thermal bridge between the surface and the surface.

dressing and structure.

  Maintaining the cladding profile on the struclure by said pads does not prevent relative sliding of the profile on the pads, allowing onc free deformation of longitudinal expansion of the profes with respect to the structure. It does not induce any constraint

in the trim profile.

  The studs according to the invention allow, as will be seen later, an easy mounting of I0 profiled on the structure and allow the same a subsequent removal of the profile without deterioration of the structure. The replacement of the profiles is greatly facilitated, whether for a repair of damaged elements, or for a modification of the appearance

aesthetics of carpentry.

  Another advantage of the cladding system is that it applies even to structures to be renovated in place. Indeed, the establishment of fixing studs does not require any particular form of carpentry, and the trim profile can be adapted to the dimensions and the :. forms

chassis in place.

  According to a preferred arrangement, the system comprises first and second bearing means of the covering profile against the structural element, located longitudinally respectively on either side of the fixing studs. Thus, the profile is more stable and

  is more resistant to the various manipulations of the window.

  The first support means are preferentieilemel constituted by a heel of the structural element and go GO second support means by a sealing joint. Once in place, this seal closes the fixing holes, which further improves the aesthetic appearance of the system. The shutter seal on the leaf can be extended along the trim profile by means of an ern P shape made of elastic material. This shape is inserted between the covering profile of the leaf and the frame and constitutes a seal. If stresses appear, the casing profile when compressing the elastic gap of the seal, when the leaf is closed, ls

  All these structural elements are made of PVC, profiled and assembled in a manner known per se. As seen in Figure 1, they comprise a central reinforcement 3, in a resistant material which gives a better riuidil &

to profiles.

  A window 5, which is preferably a painter, is included in the frame of the leaf. The tae = outside 6 of the glazing is in abutment against a jrr of Jitre 7 supported by a return 8 PV profiles, and chants 9 of the glazing are wedged inside the frame against the PVC profiles. A bead C10 is inserted into a glazing groove 11 of the profiles PV: Y and maintains the glazing of the opposite side 12 to the seal of T-re 7. One of the flanks 13 of the bead groove includes a groove 14. The The bead includes a tongue 15 of the width of the groove 11 for insertion into the groove 11. The tongue 15 is extended by a virula shape 16 to fit into the groove 14 of the groove and

  to make a locking of the baffle 10 in the groove 1 !.

  Wooden cladding profiles are curved on the inner face of the structural elements of the wood. The covering profile 20 covers the bead: and the PVC profile 2, and extends beyond the periphery of the frame of the leaf by a flap plate 21. A seal 22 foam is inserted between

  glazing 5 and the trim profile 20, Jo

  above the bead 10. In this way, the bony is no longer visible. Vis-à-vis the face 2 - t profiles 2 PVC of the door leaf, the profile of habilla-e has a T-slot 26, with a collar site t two tabs 24, 25 near the surface, and a wide bead in the heart of the profile. Between the T-slot and the bead 10, the covering profile 20 is in use

  on a heel 27 of the PVC profile 2.

  Fastening studs 30, preferably of polyamide, comprise a polygonal base - on which are fixed in superposition a part

  narrowed then a head 33. The dimension of the emos <-

  is greater than the space between the two _ancquettes "," 5, while that of the central portion 32 st is less than this distance. The head is a rectangular or oblong head, having an inside larvae of the neck between the two tabs, and the length thereof greater than that, but smaller than the wide portion of the groove, thus forming problems _4,

diametrically opposed.

  Each stud is fixed on the teachers in Pt? by I () a screw 36, for example self-drilling, [: ssanr- Jabns: 'n 37 axial drilling of the stud, slightly sere allow me to allow a rotation of the stud 30 around -a vi s ... L profile in PVC may have a small V-groove

  is one of the objectives of the invention.

  Once the fixation thus achieved, a sealing gasket 40 can be placed between the PVC profile and the covering profile 20. This sealing joint masks the studs 30, which further improves the aesthetic appearance. Preferably, the gasket is made of a rigid material, such as P 1, C 2, and thus constitutes a support for the cladding orofile 20, which ensures good stability to the l () trim profile 20 in addition resting on the heel 27 of the PVC profile 2. The sealing joint 40 is extended by a softer P-shaped portion 41 on the flap plate 21. The material of this portion 41 of the seal 40 is, for example, soft PVC, or TPE (thermoplastic elastomer). The seal 40 is obtained by coextruding the two different materials that the opart

  If one wishes to replace a trim section, scit because it is damaged, or to change the aesthetic appearance of the window on the inside, it is easy to remove the seal 40, e- to maneuver the studs 30 fastening to the mounting position to release the trim profile. Replacing

is therefore very easy.

  The described system also fits on existing joinery. Indeed, only the studs 30, fixing must be fixed on the structural elements of the joinery. The C0 esc dressing profile possibly adapted to the shape and dimensions of the carpentry, which is particularly easy with

Orofilated wooden.

  The inner face 50 of the frame 1 also receives a casing orofile 52. This profile engages in a groove 51 of the PVC profile and is retained by an ergct 3 of the PVC profile which snaps into a first groove 54 on the edge 55 of the trim profile 51.
