Description

Title of the invention: FRAME FOR JOINERY TECHNICAL FIELD AND PREVIOUS ART

[0001] The present invention relates to a joinery frame comprising a frame and a glazing bead between which a panel, for example a glazed panel, is arranged, and to joinery comprising such a frame.

[0002] Building entrances include a door assembly generally comprising a glazed door and one or more fixed sections designated as frames. The frames are also often glazed. A transom forming the upper part of the door assembly may also be provided.

[0003] The glazing is fixed to the frame by means of a glazing bead which is attached to the frame and which holds the glazing in its rebate. Generally, one or more gaskets are provided to ensure a seal between the glazing, the frame, and the glazing bead.

[0004] The fixing of the glazing bead to the frame is achieved by means of screws which cooperate with nuts crimped onto the frame.

[0005] The position of the nuts on the frame is fixed to the construction according to the thickness of the glazing.

[0006] It may be desirable to replace the glazing with glazing of a different thickness than that originally fitted to the frame. Most often, thicker glazing is preferred, particularly to improve the sound and / or thermal insulation of the door unit. However, with existing systems, it is not easy to replace glazing with glazing of a different thickness. This requires drilling new holes in the frame and crimping nuts. Such operations are not easily performed without removing the door unit. Description of the invention

[0007] It is therefore an object of the present invention to offer joinery which makes it possible to replace the shutter panel, for example the glazed panel, with glazing of a different thickness relatively easily.

[0008] The stated purpose above is achieved by a joinery comprising a frame and a glazing bead and means for fixing the glazing bead to the frame comprising at least one set of screws, and a first set of nuts, the nuts being fixed to the frame so as to be able to fix a glazing of a first thickness between the frame and the glazing bead, the joinery comprising at least a second set of nuts fixed to the frame so as to be able to fix a glazing of a second thickness between the frame and the glazing bead or another glazing bead, the second thickness being different from the first thickness.

[0009] Thus, when it is desired to replace the first pane of glass with a second pane, the installer removes the screws mounted in the first set of nuts, removes the glazing bead, and then the glass. The installer then installs the second pane of glass, replaces the glazing bead or another glazing bead, and screws the screws into the second set of nuts, the positions of which allow the screws to be directly screwed into the nuts of the second set.

[0010] Replacing the glazing is therefore significantly simplified.

[0011] The chassis may include more than two sets of nuts in different positions.

[0012] For example, a nut of one set is aligned with the nuts of the other sets in a direction perpendicular to the joinery.

[0013] The present invention relates to a frame for a window or door unit comprising at least one frame, at least one glazing bead, and at least one shutter panel mounted tightly between the frame and the glazing bead. The glazing bead is fixed to the frame by means of screws cooperating with nuts fixed to the frame. The frame comprises at least one set of nuts fixed to the frame for mounting a first shutter panel having a first thickness, and a second set of nuts fixed to the frame for mounting a second shutter panel having a second thickness different from the first.

[0014] In one embodiment, a nut from the first set and a nut from the second set are aligned in a direction orthogonal to a plane of the joinery.

[0015] The chassis is preferably made of metal and the nuts are welded to the chassis, crimped to the chassis or made directly into the chassis.

[0016] The chassis may include a rebate comprising a cheek and a bottom of rebate, the distance between the nuts of the first set and the cheek is smaller than the distance between the nuts of the second set and the cheek.

[0017] According to an additional feature, the bottom of the rebate is provided with holes, the nuts being mounted in the holes.

[0018] The present invention also relates to a joinery comprising a frame according to the invention, a glazing bead and a closing element between the frame and the glazing bead, the glazing bead being fixed to the frame by means of screws cooperating with the first set of nuts or the second set of nuts, the closing panel being for example a glazed panel.

[0019] The glazing bead is advantageously in one piece.

[0020] The present invention also relates to a door block comprising at least one joinery according to the invention.

[0021] The present invention also relates to a method for replacing a first shutter panel of a first thickness with a second shutter panel of a second thickness in a joinery according to the invention or the door block according to the invention, comprising the steps: - Removal of the screws cooperating with the nuts of the first set, - Removal of the glazing bead, - Removal of the first closing panel, - Installation of the second shutter panel, - Installation of a glazing bead adapted to the second shutter panel, - Mounting the screws into the nuts of the second set.

[0022] The glazing bead adapted to the second shutter panel may be different from the glazing bead adapted to the first shutter panel. Brief description of the drawings

DETAILED DESCRIPTION OF IMPLEMENTATION METHODS

[0024] In the following description, "joinery" means an assembly comprising a frame, at least one panel closing the frame, generally formed by glazing, and at least one glazing bead. The joinery may be movable, forming a door, or fixed. The door may be sliding or hinged for rotation.

[0025] In [Fig.1], we can see an example of a door block intended to close the entrance of a building lobby and to which the present invention can be applied.

[0026] The door assembly comprises a door P forming the opening and cooperating with a frame, two fixed parts on either side of the door Fl, F2 and a transom I at the top. The fixed parts Fl and F2 are also commonly referred to as "fixed frames".

[0027] In this example, each of the elements of the door block includes at least one glazed part.

[0028] The door comprises a single pane of glass, as well as the transom and fixed parts. It will be understood that this configuration is only an example of an embodiment and is in no way limiting.

[0029] Figures 2 to 7 show views of the fixed part Fl of the door block of [Fig.1].

[0030] The fixed part Fl comprises a frame 2, a glazing (not shown) and a glazing bead 4. Preferably, the glazing bead 4 is mounted on the face of the frame 2 intended to be inside the building.

[0031] In the example shown, the frame 2 has a rectangular shape and the glazing bead 4 also has a corresponding rectangular shape, comprising a bearing portion 4.1 intended to bear against one face of the frame 2 and a fixing edge 4.2 intended to penetrate the frame and secure the glazing bead to the frame. The external dimensions of the fixing edge 4.2 are such that it penetrates the frame 2 with a mounting clearance. It will be understood that the frame and the glazing bead can have any other shape, for example, any polygonal shape, or even a circular shape.

[0032] The frame has a rebate 6 which houses the edge of the glazing. The rebate 6 is delimited by a cheek 8 and a rebate bottom 10. The edge of the glazing is then pinched between the cheek 8 and the glazing bead 4.

[0033] The joinery includes means for fixing 12 of the glazing bead 4 onto the frame 2.

[0034] The fixing means comprise nuts fixed to the frame and accessible through the bottom of the rebate and screws cooperating with the nuts, the screws passing through the fixing edge 4.2 of the glazing bead.

[0035] In the example shown, the chassis includes two sets of nuts El, E2

[0036] The first set of nuts E1 is fixed to the frame at a distance d1 from the side panel, and the second set of nuts E2 is fixed to the frame at a distance d2 from the side panel. The distances d1 and d2 are considered in a direction orthogonal to the plane of the joinery.

[0037] The nuts are distributed around the circumference of the chassis.

[0038] In [Fig. 2], it can be seen that the fastening means 12 comprise one nut across the width of the chassis and two nuts along the length of the chassis. In this example, the chassis therefore has six fastening areas.

[0039] In this example, each fixing area includes a nut from the first set and a nut from the second set.

[0040] The rebate base 10 has two holes 16, 18 at each fixing point, in each of which a nut from each set is fixed. The nuts are, for example, welded to the frame. Alternatively, the nuts are crimped onto the frame. Again, the nuts are made directly in the chassis; for this, the chassis is tapped at the location of the holes.

[0041] The glazing bead 4 has holes 22 arranged so as to be aligned with the nuts.

[0042] It is conceivable that the glazing bead is configured for a specific thickness of glazed panel and has its own arrangement of nuts, thus forming a means of error-proofing the choice of the glazing bead.

[0043] An example of a method for replacing the glazed panel of a fixed frame will now be described.

[0044] The glazed panel of a first thickness is initially mounted between the frame 2 and the glazing bead 4, and the screws are screwed into the nuts of the EL set

[0045] We wish to replace the glass panel with a second panel of greater thickness than the first thickness.

[0046] The assembler then removes the screws screwed into the first set of nuts, removes the glazing bead 4 and removes the glazed panel.

[0047] He then places the second-thickness glass panel into the frame 2, replaces the glazing bead 4 if it is suitable, or uses a thinner glazing bead to compensate for the increased thickness of the glass panel. The holes in the glazing bead 4 are directly aligned with the nuts of the second set; the installer then screws the screws into the nuts of the second set.

[0048] The assembly is complete. Replacement is then quick and does not require drilling the chassis.

[0049] In the example shown, the nuts of the two sets of nuts are grouped in each fixing zone ZI.

[0050] Alternatively, as shown in [Fig. 8], the nuts in one set have their fixing area Z1 and the nuts in another set have their fixing area Z2. Alternatively still, some nuts in both sets have the same fixing areas and the nuts in both sets have different fixing areas.

[0051] It may be envisaged that the two sets of nuts do not have the same number of nuts.

[0052] Furthermore, it is possible that the nuts in the two sets may be different, for example, have different diameters. In this case, the screws used to fix the first-layer glass panel are different from those used to fix the second-layer glass panel.

[0053] It will be understood that each frame may include more than two sets of nuts, for example three, allowing a panel of a third thickness to be fixed.

[0054] In the example shown, the glazing bead is a single piece. Alternatively, the glazing bead may be in several parts.

[0055] In this example, the glazing bead has a cheek that rests against one face of the frame. Alternatively, the glazing bead does not have such a cheek and is entirely housed within the frame.

[0056] As explained above, the glazed panel can be replaced by an opaque panel.

[0057] Thanks to the invention, the replacement of a panel, in particular a glazed panel, by a panel with a greater thickness, in a joinery is considerably simplified and does not require the use of a specific tool.
