Description

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 typically include a door unit consisting of a glazed door and one or more fixed sections called frames. The frames are also often glazed. A transom window forming the upper part of the door unit may also be included.

[0003] The glazing is secured to the frame using a glazing bead, which is fixed to the frame and holds the glazing in its rebate. Generally, one or more gaskets are used to ensure a watertight seal between the glazing, the frame, and the glazing bead.

[0004] The glazing bead is fixed to the frame 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 a pane of glass of a different thickness than the one 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 glass 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.

[0007] US documents 2013 / 047524 A1 and US 2023 / 272666 A1 show joinery frames comprising a frame, a glazing bead and a shutter panel. DESCRIPTION OF THE INVENTION

[0008] It is therefore one aim of the present invention to provide joinery which makes it relatively easy to replace the shutter panel, for example the glazed panel, with glazing of a different thickness.

[0009] The objective stated above is achieved by a window assembly comprising a frame and a glazing bead, and means for fixing the glazing bead to the frame, including at least one set of screws and a first set of nuts. The nuts are fixed to the frame in such a way as to allow for fixing a first pane of glazing between the frame and the glazing bead. The assembly also includes at least a second set of nuts fixed to the frame in such a way as to allow for fixing a second pane of glazing between the frame and the glazing bead, or a different glazing bead, the second pane being different from the first. The first and second sets are located in two different planes, parallel to the frame.

[0010] Therefore, when replacing the first pane of glass with a second pane, the installer removes the screws from the first set of nuts, then removes the glazing bead and the glass itself. They then install the second pane of glass, replace the glazing bead (or a different one), and screw the screws into the second set of nuts, which are positioned to allow direct screwing into the nuts of the second set.

[0011] Replacing the glazing is therefore significantly simplified.

[0012] The chassis may have more than two sets of nuts in different positions.

[0013] For example, a nut in one set is aligned with the nuts in other sets in a direction perpendicular to the woodwork.

[0014] 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 includes at least one set of nuts fixed to the frame for mounting a first shutter panel of a first thickness and a second set of nuts fixed to the frame for mounting a second shutter panel of a different thickness than the first.

[0015] The first set and the second set are located in two different planes, parallel to the chassis.

[0016] In one example of implementation, 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.

[0017] The chassis is preferably made of metal and the nuts are welded to the chassis, crimped onto the chassis or made directly into the chassis.

[0018] The frame may include a rebate comprising a cheek and a bottom of the 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.

[0019] According to an additional feature, the bottom of the rebate is provided with holes, the nuts being mounted in the holes.

[0020] 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.

[0021] The glazing bead is advantageously made of a single piece.

[0022] The present invention also relates to a door block comprising at least one piece of joinery according to the invention.

[0023] 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 unit according to the invention, comprising the following 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 closing panel, Installation of a glazing bead adapted to the second closing panel, Mounting of the screws in the nuts of the second set.

[0024] The glazing bead suitable for the second shutter panel may be different from the glazing bead suitable for the first shutter panel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF IMPLEMENTATION METHODS

[0026] In the following description, "joinery" refers to an assembly comprising a frame, at least one panel covering the frame (generally a pane of glass), and at least one glazing bead. Joinery can be movable, forming a door, or fixed. The door can be sliding or hinged.

[0027] On the figure 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.

[0028] The door assembly comprises a door P forming the opening and cooperating with a frame, two fixed parts on either side of the door F1, F2 and a transom I at the top. The fixed parts F1 and F2 are also commonly referred to as "fixed frames".

[0029] In this example, each of the elements of the door block includes at least one glazed part.

[0030] The door includes a single pane of glass, a transom, and fixed panels. It should be understood that this configuration is merely an example and is in no way exhaustive.

[0031] On the figures 2 to 7 We can see views of the fixed part F1 of the door block of the figure 1 .

[0032] The fixed part F1 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.

[0033] In the example shown, the frame 2 is rectangular, and the glazing bead 4 is also rectangular, comprising a bearing portion 4.1 designed to rest against one face of the frame 2 and a fixing edge 4.2 designed to penetrate the frame and secure the glazing bead to it. The external dimensions of the fixing edge 4.2 are such that it penetrates the frame 2 with a mounting clearance. It should be understood that the frame and the glazing bead can have any other shape, for example, any polygonal shape, or even a circle.

[0034] 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.

[0035] The joinery includes means of fixing 12 of the glazing bead 4 onto the frame 2.

[0036] The fixing means include 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.

[0037] In the example shown, the chassis has two sets of nuts E1, E2. The first set and the second set are in two different planes, parallel to the chassis.

[0038] 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.

[0039] The nuts are distributed around the circumference of the chassis.

[0040] On the figure 2As can be seen, the fastening means 12 include one nut across the width of the chassis and two nuts along its length. In this example, the chassis therefore has six fastening points.

[0041] In this example, each fixing area has one nut from the first set and one nut from the second set.

[0042] The rebate base 10 has two holes 16 and 18 at each fixing point, into 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. As a further alternative, the nuts are machined directly into the frame; for this purpose, the frame is tapped at the locations of the holes.

[0043] The glazing bead 4 has 22 holes arranged so as to be aligned with the nuts.

[0044] It is conceivable that the glazing bead could be configured for a specific glass panel thickness and have its own nut arrangement, thus providing a means of error-proofing the choice of glazing bead.

[0045] An example of a method for replacing the glass panel of a fixed frame will now be described.

[0046] The first layer of glass is initially mounted between the frame 2 and the glazing bead 4, and the screws are screwed into the nuts of the E1 set.

[0047] We want to replace the glass panel with a second layer of glass that is thicker than the first layer.

[0048] The installer then removes the screws screwed into the first set of nuts, removes the glazing bead 4 and removes the glass panel.

[0049] He then places the second-layer glass panel into frame 2, replaces the glazing bead 4 if it is suitable, or uses a thinner one 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.

[0050] The assembly is complete. Replacement is then quick and does not require drilling into the chassis.

[0051] In the example shown, the nuts from both sets of nuts are grouped in each fixing zone Z1.

[0052] Alternatively, as shown on the figure 8 The nuts in one set have their fixing zone Z1 and the nuts in another set have their fixing zone Z2. Alternatively, some nuts in both sets have the same fixing zones and nuts in both sets have different fixing zones.

[0053] It is possible that the two sets of nuts may not have the same number of nuts.

[0054] Furthermore, it is possible that the nuts in the two sets are different, for example, they may have different diameters. In this case, the screws used to fix the first layer of glass are different from those used to fix the second layer of glass.

[0055] 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.

[0056] In the example shown, the glazing bead is a single piece. Alternatively, the glazing bead can be made of several parts.

[0057] 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.

[0058] As explained above, the glazed panel can be replaced by an opaque panel. Thanks to the invention, replacing a panel, particularly a glazed panel, with a thicker panel in a window or door frame is significantly simplified and does not require the use of any special tools.
