Description

DESCRIPTION

Door leaf with panel and panel kit for said door leaf

[0001] The present invention relates to a panel door leaf, more particularly to a door leaf intended to be hingedly mounted on a door frame.

[0002] In particular, the invention concerns a type of door leaf that includes a frame and a door panel with a front sheet and a back sheet and a possible intermediate sheet between both, where the frame is made of traditional profiles with a a front wall and a rear wall at the front and rear of the frame, respectively, an internal wall and an external wall at the internal margin and the external edge of the frame, respectively, and on the internal wall of the profiles an inwardly facing flange to form a recess.

[0003] Adhesion of the front sheet against the front of the frame is a known technique, with the front of the frame at least partially covered.

[0004] One disadvantage that occurs with bonded front sheets is the large temperature differences between the front sheet and the back sheet, for example, when the front sheet is exposed to full sunlight and the back sheet is at shadow.

[0005] In such a case, there is a risk that the front sheet will expand and bend outward, which is obviously not desirable for the appearance of the door.

[0006] In addition, this causes unwanted stresses on the door leaf and door frame, which can, for example, cause the lock built into the frame to stop working properly.

[0007] Another disadvantage is that the adhesion of the front sheet to the frame during assembly is relatively laborious and must be done under controlled conditions.

[0008] Still another disadvantage is that the lateral movement of the front sheet on the frame, for example to align the front sheet with the frame or the lock, becomes very difficult as the adhesive hardens.

[0009] An additional disadvantage is that a bonded front sheet can no longer be removed without damaging the outer door.

[0010] From WO 2016/112437, from the same applicant, another technique is known for fastening the front sheet to the frame using fastening means formed by one or more clamps along the perimeter of the frame with a base element that it is attached to the front sheet with a clamping arm at the top which hooks behind the aforementioned flange and which can be adjusted on the base member towards the front sheet by screws.

Although this technique offers indisputable advantages, in this case there is a problem that, with extreme temperature differences, the front sheet can be deformed, although to a lesser extent than in the case of bonded front sheets.

[0012] The screwing of the fastening means during assembly is relatively laborious, since the screws must also be precisely fixed with a tightening that is not too weak to achieve sufficient permanent fixation, but is not too strong either. Avoid damages.

[0013] The purpose of the present invention is to provide a solution to one or more of the above mentioned disadvantages and other disadvantages.

To this end, the invention relates to a door leaf of the type described above, but in which the front sheet is attached to the frame by means of at least one or more first coupling parts which are attached to the sheet. front, and by one or more cooperating second coupling parts fixed in the rear sheet or in the intermediate sheet, where the first coupling parts and the second coupling parts magnetically attract each other, in such a way that the magnetic cooperation of the Coupling parts causes the backsheet or intermediate sheet to catch behind the aforementioned flange and be attracted against it such that movement between the coupling parts is allowed in a direction parallel to the surface of the front sheet.

[0015] An advantage is that the fixing of the front sheet is very simple and can be carried out very quickly by simply doing the following, for example:

- either by first placing and fixing the rear sheet, or the intermediate sheet if there is one, in the recess of the frame, for example by means of a reed as is already known, and then placing the front sheet against the front wall of the frame to magnetically couple the front sheet with the back sheet or the intermediate sheet;

- or by first placing the frame with its front wall on the front sheet and then placing the back sheet or the intermediate sheet, if any, in the frame recess to magnetically couple the coupling parts together with the aforementioned flange clamping above the frame between the front sheet and the back sheet or intermediate sheet.

[0016] Then, at this assembly stage, the front sheet can, if necessary, be moved additionally for its correct alignment with the frame.

[0017] This is possible because the magnets have a significant attractive force to each other in a direction perpendicular to their contact surface, but only offer a small resistance against lateral movement in the direction of the contact surface.

[0018] For the same reason, the magnetic coupling will offer little resistance to the lateral expansion of the front sheet, for example, because sunlight falls on it.

[0019] As a result, the front sheet, frame or frame profiles will not deform due to expansion, nor will the complex door lock system.

[0020] Another advantage of the invention is that, in addition to the magnetically cooperating coupling parts, no other means is required to hold the front sheet against the frame.

[0021] Because most of the existing doors consist of the traditional flanged profiles mentioned above, the invention is also suitable for the reform of existing doors.

[0022] In this case, it is useful for the front sheet to completely cover the front of the frame, so that the entire door appears to be new. This can also come in handy for new doors to give them a clean, modern look.

[0023] Preferably, the first and second coupling parts are applied behind the front sheet so that they are not visible on a finished door.

[0024] Preferably, of each pair of first and second coupling parts, at least one coupling part is in the form of a permanent magnet, while the other coupling part is made of a material that is attracted or repelled by a magnet eg in the form of a second magnet or a steel plate.

[0025] If an intermediate sheet is not provided, the dimensions of the rear sheet are slightly smaller than the dimensions of the frame recess, and in that case the space between the rear sheet and the rear of the frame is covered by panel slats or decorative slats.

[0026] If there is an intermediate sheet, the dimensions of the rear sheet are preferably larger than the dimensions of the frame recess and the dimensions of the intermediate sheet are slightly smaller than these dimensions of the recess, whereby the intermediate sheet is is attracted to the flange by magnetic cooperation between the first and second coupling parts, and the backsheet is attracted to the rear of the frame due to magnetic cooperation between the third and fourth coupling parts that are attached to the intermediate sheet and back sheet, respectively.

[0027] The advantages of the described magnetic holding means for holding the front sheet in the frame obviously apply also to the magnetic fixing of the back sheet in the frame.

[0028] Also in that case, the third and fourth coupling parts are invisibly applied between the backsheet and the intermediate sheet.

[0029] Preferably, the backsheet covers the entire back wall of the frame and the backsheet is provided with folded edges that hook along the outer perimeter of the back wall of the frame, for example completely around or only along its length. from the vertical edges.

[0030] The invention also relates to a panel kit for assembling a door leaf as described, starting with a frame made of traditional profiles with a flange to form a recess, where this panel kit contains at least one of the following elements or a combination of one or more of these elements:

- a front sheet with one or more first coupling parts attached to it at a certain distance from the perimeter that form part of the fastening means to be able to hold the front sheet on the frame; - second coupling parts for fixing on a backsheet or on an intermediate sheet, where the second coupling parts can magnetically cooperate with the first coupling parts;

- a backsheet and / or a loose intermediate sheet that may or may not be provided with the second coupling parts.

[0031] With the intention of better showing the characteristics of the invention, some preferred embodiments of a door leaf according to the invention are described below by way of example, without limitation, and of a panel kit for said door leaf, with reference to the attached drawings, where: figure 1 schematically shows an external door with PVC profiles according to the invention seen from the front;

figure 2 shows a cross section according to line II-II of figure 1;

Figure 3 shows the cross section as shown in Figure 3, but with the door leaf in the unassembled state;

figure 4 shows a rear view according to arrow F4 of figure 3;

Figure 5 shows a variant of a door leaf according to the invention for an external door with PVC profiles;

Figures 6 to 8 show other variants of a door leaf according to the invention, however, in this case for an external door with aluminum profiles.

[0032] The outer door 1 shown in Figure 1 includes a fixed door frame 2 intended to be fixed in a wall hole and a door leaf 3 hinged inside.

[0033] The door leaf 3 is formed by a frame 4 and a door panel 5 applied thereto which is in the form of a sandwich panel with a front sheet 6 in the front part of the door, more particularly in the outside of door 1, and a rear foil 7 at the rear, more particularly inside door 1.

[0034] The front sheet 6 is made, for example, of an aluminum plate and the rear sheet 7 is made, for example, of an XPS plate covered on the visible side with an aluminum or PVC 8 coating.

[0035] The frame 4 of the door leaf 3 is a traditional frame 4 that is made up of traditional profiles 9, for example of a synthetic material reinforced with an internal metal profile as shown in Figures 2 to 5.

[0036] The profiles 9 have a front wall 10 and a rear wall 11, at the front and rear of the frame 4 respectively, an inner wall 12 and an outer wall 13, at the inner edge and at the outer edge of the frame 4 respectively, and on the inner wall 12 of the profiles 9, a rim 14 oriented inwards to form a recess 15, where the rim 14 in the example shown is provided with a weatherstrip 16 along its entire profile.

[0037] The front sheet 6 in the example shown covers the entire front wall of the frame 4, while the back sheet 7 has dimensions greater than the dimensions A of the frame 4 along the inner perimeter of the rim 14, but smaller that the dimensions of the recess B along the inner wall 12.

[0038] The backsheet 7 is attracted to these weatherstripping 16 by means of coupling means 17 which are formed by the first coupling parts 18a fixed to the rear of the front sheet 6 and which cooperate with the second coupling parts 18b affixed to the side of the backsheet facing the front sheet 6.

[0039] The first and second coupling parts18a and 18b are designed to magnetically attract each other in the X-X 'direction perpendicular to the surface of the front sheet 6.

[0040] In the example shown, the second coupling parts 18b are provided as permanent magnets held by plywood spacers 19 against the backsheet, for example by means of screws 20.

[0041] The first coupling parts 18a in this case are in the form of steel plates which can be attracted by the magnets of the second coupling parts. Alternatively, these first coupling parts 18a can also be in the form of permanent magnets.

[0042] The first coupling parts 18a adhere, for example, to the rear of the front sheet 6, but can also be welded thereon.

[0043] As shown in figure 4, the first coupling parts 18a are limited to a distance from the internal perimeter of the frame 4 by the internal edges of the flanges 14 of the profiles 9.

[0044] The second coupling parts are applied in the corresponding positions on the back sheet 7.

[0045] Instead of using separate coupling parts 18 as in Figure 4, coupling parts in the form of continuous magnetic strips or tapes can also be used.

[0046] The coupling parts 18a and 18b are assembled such that, in the assembled state, movement between the coupling parts 18a and 18b is possible in a direction YY 'parallel to the surface of the front sheet 6 orthogonally with respect to the direction XX 'mentioned above.

[0047] For this purpose, the coupling parts are assembled so that their contact surface 21 is parallel to the surface of the front sheet 6. A characteristic of the magnetic coupling parts 18a and 18b is that they strongly attract each other in the XX 'direction corresponding to the NS direction of the magnets and only offer little or no resistance against movement in the Y-Y direction'.

[0048] The magnetic attraction force between the coupling parts 18a and 18b firmly holds the flange 14 of the frame between the front sheet 6 and the back sheet 7 as shown in figure 2.

However, movement of the front sheet 6 with respect to the back sheet 7 and the frame is still possible in this assembled state.

This allows the possible lateral expansion of the front sheet 6 with respect to the frame without the deformation of the front sheet 6 and without causing great internal stresses.

[0051] Once the front sheet and the back sheet are assembled, the recess 15 between the perimeter of the back sheet 7 and the inner wall 12 of the frame 4 is covered by means of a panel slat 22 which is fastened around the side rear on frame 4 and which is provided with a second weatherstrip 13 which presses on the back of the door panel as clearly shown in figure 2, so that the door panel 5 is fastened along its edges between weatherstripping 16 and 23, flange 14 and panel slat 22 respectively.

[0052] FIG. 5 shows a variant embodiment of a door leaf 3 according to the invention, in which, in this case, a backsheet 7 is applied together with an intermediate sheet 24.

[0053] In this case, the dimensions of the intermediate sheet 24 are greater than the dimensions A of the frame 4 along the inner perimeter of the rim 14, but smaller than the dimensions of the recess B along the inner wall 12 and the intermediate sheet is attracted by the magnetic coupling parts 18a and 18b against the weatherstrip 16 of the flange 14.

[0054] In this case, the backsheet 7 covers the entire back wall 11 of the frame and is fitted with a folded edge on the perimeter of the outer wall 13 of the frame 4.

[0055] This rear sheet 7 is drawn against the rear wall 11 of the frame 4 by the magnetic cooperation between the third coupling parts 26a and the fourth coupling parts 26b which are attached to the intermediate sheet 24 and to the rear sheet 7, respectively .

[0056] It is clear that, instead of a magnetic coupling, the backsheet can also be fastened in another mechanical way or by adhesion, in combination with a magnetic coupling of the front sheet.

[0057] The intermediate sheet 24 can be optionally fastened to the frame 4 by means of a panel slat 22 mentioned above or by means of an additional profile 27 which rests against the rear of the intermediate sheet 24 and is fixed on the inner wall 12 of frame 4, for example with a screw 28.

[0058] Figures 6 and 7 show variant embodiments of a door leaf 3 according to the invention which are analogous to the embodiments of Figures 2 and 5 but with the difference that in this case the frame 4 is made of traditional 9 aluminum profiles instead of PVC

[0059] The same characteristics as in Figures 2 and 5 are present.

[0060] Figure 8 shows a variant of Figure 2 in which the first and second coupling parts 18a and 18b are in the form of magnets assembled in such a way that they repel each other in the XX 'direction and are assembled on the front sheet 6 and on the backsheet 7 with the repellent forces oriented in such a way that they push the front sheet 6 and the backsheet 7 towards each other.

[0061] In this case, the magnets 26a and 26b do not necessarily have to be in contact with each other as shown in figure 8.

[0062] More generally, the coupling parts 18a and 18b and the coupling parts 26a and 26b do not necessarily have to be in contact with each other, nor if they attract each other. This means that the surface of Contact 21 in that case does not necessarily have to be parallel to the surface of the front sheet 6 to allow lateral movement of the coupling parts to each other.

[0063] The present invention is by no means limited to the embodiment as described by way of example and as shown in the drawings, but a door leaf and panel kit according to the invention can be made in all kinds of variants and dimensions, without departing from the scope of the invention.
