DOOR LEAF AND METHOD FOR INSTALLING AND REMOVING A

PANEL MOUNTED IN SUCH A DOOR LEAF

1. Field of the invention

The invention relates to the field of door leaves incorporating a panel. It relates more particularly to a door leaf as well as a method of fitting and removing a panel mounted in such a door leaf.

. Prior art

For practical or aesthetic reasons, some door leaves incorporate a panel, for example glazing, a mirror or a full decorative panel. As shown in Figures 1 to 3B of the prior art, the panel is conventionally mounted in an opening of the leaf and held in place in the opening by at least one glazing bead. The glazing bead is conventionally a wooden, plastic, steel or aluminum frame.

In the case of wooden glazing beads, several fixing means are possible.

First, there is a fixing by points or screws where each glazing bead is fixed in the filling of the leaf using points or screws if the material constituting the filling of the leaf is sufficiently rigid. This case is illustrated by FIG. 1 which represents a panel C held in a leaf opening B by two glazing beads DI and D2 placed on either side of panel C and fixed to leaf A by points F.

Second, there is a pinch attachment where the panel is supported on a leaf rebate and where the panel pinch between the leaf and a glazing bead

allows keep in place the breakdown at. The figure 2A represented a fixation through pinch in which the glazing beads flower on one side leaf and the figure 2B represented a fixation through pinch in which the

glazing bead flush. Thus, in FIGS. 2A and 2B, the glazing beads DI 'and DI' 'are fixed respectively to the leaves A' and A '' by points F 'and F' '. A panel is intended to be placed in the opening B 'or B' 'to be clamped between the glazing bead DI' or DI '' and a rebate H 'or H' 'of the leaf. Thus, the rebate allows the reception and the maintenance of the panel. In FIG. 2A, the glazing bead DI 'is integrally mounted in the opening B' so as to be flush with the face 1 'while in FIG. 2B, the glazing bead DI' 'is flush, that is to say that it is mounted so as to have a rebate of the glazing bead DI '' resting on a side I '' side of the leaf. However, this fixing by pointing or screwing degrades the aesthetics of the leaves, in particular on lacquered leaves. In addition, the installation time of the panel includes the penalizing durations of the pre-drilling and pointing or screwing stages.

Thirdly, there is a fixing by gluing where the glazing beads are glued on the leaf. The panel is then hardly removable. In addition, this solution adds an industrial constraint linked to the waiting time for setting the glue.

In the case of steel or aluminum glazing beads, there is the means of fixing by screws. The screws are then binding screws which make it possible to fix together two glazing beads placed on either side of the panel so as to take the panel in a vice. This case is illustrated in FIG. 3A in which a panel C '' 'is placed in the opening B' '' of the leaf A '' 'and the glazing beads Dl' '' and D2 '' 'are placed respectively on a first side II '' 'side and on a second side 12' '' side of the leaf Ά '' 'so as to grip the panel C' ''. The glazing beads DI '' 'and 02' '' are fixed to each other by screws E '' '. The glazing beads Dl '' 'and D2' '' are mounted so as to have a rebate of the glazing bead pressing respectively on the first side II '' 'side and on the second side 12' '' side of leaf A '' ' . A disadvantage of this solution lies in the fact that the screws are visible.

As regards the plastic glazing beads, they may have clips made integrally with the glazing beads and used for fixing as shown in Figure 3B. A fixing by clip has the advantage of taking the panel in a vice without the need for fixing in the filling of the leaf. This case is represented in FIG. 3B in which a panel C '' '' is placed in an opening B '' '' of a leaf A '' '' and in which the panel C '' '' is held in place by two glazing beads Dl '' '' and D2 '' '' clipped together. Each clip includes a lug J '' '' secured to a glazing bead and a housing K '' '' intended to receive the lug in another glazing bead. However, clip glazing beads are difficult to dismantle, in particular because of the risk of clips breaking, and have a large size on the face of the leaf.

6. Detailed description

Figures 4 to 8A relate to a door leaf 1 according to a first embodiment of the invention.

They are oriented along a longitudinal axis X parallel to the width of the leaf and pointing to the right, a transverse axis Y parallel to the depth or the thickness of the leaf pointing backwards and a vertical Z axis parallel to the height of the leaf and pointing up.

The door leaf 1 comprises a leaf frame 2 and a panel 3. The panel 3 is integrated into the leaf 1 for aesthetic or practical questions. For example, panel 3 is a glazing allowing light to pass through and to see through the leaf. The panel can also be a mirror in order to produce an impression of depth or luminosity in the room where the leaf 1 is located. According to another example, the panel is a panel full of decoration.

The leaf frame 2 has a first face 21 in the XZ plane and a second face 22 in the XZ plane, opposite the first face 21. The frame 2 gives its structure to the leaf and has a first covering facing 201 on the first face 21, a second covering facing 202 on the second face 22, a frame 203 on the periphery of the leaf, a filling 204 in the space delimited by the facing and the frame as well as an opening 5 defining the location from panel 3.

The opening 5 is either non-through, for example when it is formed only in the first face 21, or through when it crosses from the first face 21 to the second face 22. The opening has dimensions in the XZ plane very slightly larger than the dimensions of the panel 3 in this same plane so that the panel can be mounted in the opening 5.

The panel is held in the opening 5 by a first glazing bead 41 mounted on the first face 21 and a second glazing bead 42 mounted on the second face 22. The first glazing bead 41 and the second glazing bead 42 each have a profile comprising a retaining rabbet 410 and 420 mounted to bear on the first face 21 and the second face 22 respectively. The retaining rabbets 410 and 420 make it possible to prevent the assembly formed by the panel and the glazing beads from sliding in the opening 5 in the transverse direction. Optionally, the positioning of the panel in the opening can be adjusted using one or more shims 7.

Alternatively, the leaf has only one glazing bead, for example in the case where the opening is not through or in the case where the leaf frame has a rabbet for receiving and holding the panel as illustrated in the figures 2A and 2B.

The first glazing bead 41 is clipped by means of an elastically deformable fixing system 6 and comprising a lug 60 intended to cooperate with a housing 9 to form a stop. The fixing system is located between the two retaining rabbets 410 and 420.

In the example of the figures and with particular reference to FIG. 7, the fixing system 6 is integral with the second glazing bead 42 and the housing 9 is in the first glazing bead 41. In fact, the fixing system 6 is fixed by means a screw 10 in the second glazing bead 42 and the lug 60 is placed in the housing 9 formed in the first glazing bead 41. The housing 9 is for example formed by machining or molding in the first glazing bead 41. For the sake of standardization glazing beads and to avoid the creation of two geometries "male" and "female" glazing beads, the two glazing beads may have the same moldings or machining materializing the locations of screws and housings.

According to variants not shown:

the fixing system is secured to the first glazing bead and the housing is in the leaf frame, or - the fixing system is secured to the leaf chassis and the housing is in the first glazing bead.

In the example of the figures, the fixing system 6 is a separate part from the element of which it is intended to be integral, in this case, the second glazing bead 42. According to a variant embodiment not shown, the fixing system came integrally with the element of which it is intended to be integral.

With particular reference to FIGS. 7 and 8A, the fixing system 6 is produced in a plate. By way of illustration and in no way limitative, the fixing system is made of metal, for example steel, or plastic; the plate has a thickness of 0.4 to 10 millimeters.

The fixing system comprises a body 61 in the form of a blade representing the main part of the plate and a lug 60. The lug 60 is a strip connected to the body 61 of the fixing system by a junction 63. The entire system of fixing is elastically deformable. According to an exemplary embodiment, the strip projects from the body 61 of the fastening system in a rest position and is placed in a plane substantially tangent to the body 61 of the fastening system in a position under stress. The lamella has a rectangular shape. It can be obtained by cutting the plate along three sides of the rectangle, one side in the length and two sides in the width then by folding along the fourth side of the rectangle. The fourth side of the rectangle then forms the junction 63. The strip can also be obtained by stamping. The body 61 of the fastening system also includes a through hole 62 corresponding to the location of the screw 10.

The leaf also comprises an elastically deformable seal 8 placed in the opening 5 bearing on the panel 3. The seal 8 makes it possible to absorb the variations in thickness and the operating clearances generated by the manufacturing tolerances. Without a seal, the glass could hit the glazing bead, which would cause noise pollution. The seal is for example made of foam.

According to an alternative embodiment shown in FIG. 8B, the fixing system comprises a body 61 ′ in the form of a blade representing the main part of the plate and a lug 60 ′. The lug 60 'is a strip connected to the body 61' of the fixing system by a junction 63 '. The entire fixing system is elastically deformable. According to an exemplary embodiment, the strip protrudes from the body 61 'of the fixing system in a rest position and is placed in a plane substantially tangent to the body 61' of the fixing system in a position under stress. The strip has a rectangular shape extending over the entire width of the plate. It can be obtained by folding the plate at junction 63 '. The body 61 'of the fixing system also includes a through hole 62' corresponding to the location of the screw 10.

According to an alternative embodiment shown in FIG. 9, the housing 9 ′ comprises a succession of teeth 90 ′ arranged in a rack in the thickness of the glazing bead so that the glazing bead is clipped in an adjustable manner for different thicknesses of panel, the fixing system remaining identical to that previously described.

According to another alternative embodiment shown in FIG. 10, the 6 '' fastening system comprises a succession of lugs 64 '', 65 '', 66 '' arranged offset in the thickness of the leaf so that the first glazing bead is clipped in an adjustable manner for different thicknesses of panel, the housing remaining identical to that previously described in Figures 4 to 8A.

There are also provided a method of fitting and a method of removing a leaf panel according to the invention.

The installation process includes steps of:

- Installation of the panel in the opening of the leaf frame,

- Installation of the glazing bead on the first face so as to keep the panel in the opening,

- Clipping of the first glazing bead in place.

The removal process includes steps of:

- Insertion between the panel and the first glazing bead, for example at the joint, of a spacing means having an adapted shape,

- Spacing of the lug and the housing so as to remove the stop,

- Removal of the first glazing bead from the first side,

- Removal of the panel outside the opening.

The invention is described in the foregoing by way of example. It is understood that the person skilled in the art is able to carry out different variant embodiments of the invention, for example by combining the different characteristics above taken alone or in combination, without however departing from the scope of the invention claimed.
