Description

[0001] The invention relates to a frame for a door with extruded frame profiles with a threshold, a door with such a frame and a method for manufacturing the same. Technical field

[0002] Plastic has become established as a material for frame profiles in the manufacture of windows and doors in many markets due to its efficient processing and the durability of the products. Plastic profiles are generally cut at a miter and welded together at the miter joint to form a frame. At least in larger manufacturing operations, the production of frame and sash profiles from plastic profiles typically takes place on complex production lines where the individual work steps are carried out sequentially in a timed sequence. To enable efficient production, no single work step may take significantly longer than others, as otherwise the entire production line would have to be operated at a correspondingly slower speed.

[0003] Many doors have a frame with the same profile on all sides. This has the advantage that the frame can be welded at the four corners, improving both airtightness and strength. However, this creates the problem that the frame protrudes above the floor, posing a tripping hazard. To avoid this, especially in public buildings and accessible housing, thresholds are installed at floor level instead of the frame profile used on the other sides. These thresholds are usually screwed to the rest of the frame. Ensuring proper sealing and drainage in this case is relatively complex.

[0004] In the case of sliding doors, such as those known from DE 202007015160 U1, the threshold must be formed from different profiles than the other three sides in order to accommodate the running track. State of the art

[0005] German patent DE 4441289 A1 discloses a balcony or patio door with a threshold profile rail that can be mounted on the frame. To prevent water from entering the building, the profile rail has a water collection channel at the transition to the frame profile. The water that collects in this channel is drained away to the sides, necessitating a corresponding drainage system.

[0006] DE 102004016079 A1 discloses a door in which both the sash frame and the frame are manufactured entirely from identical profiles. In the frame, the overlap at the threshold is filled by the use of a threshold profile. This makes the frame slightly higher at the threshold than the frame alone.

[0007] DE 102017103254 shows a threshold profile of a frame in which the outer profile flange of the lower profile is interrupted. A threshold profile is inserted into this area. Drainage occurs through the threshold. The threshold must be sealed watertight to the frame profile, which requires considerable effort at the transition points. This is particularly important because dynamic forces are introduced via the tread surface when walking on it, resulting in dynamic stress on the connection to be sealed. Task

[0008] The object of the present invention is therefore to provide a generic frame for a door with a threshold, which can be easily combined with a welded frame and allows for simple drainage. Description of the invention

[0009] The invention solves this problem by providing a frame for a door, preferably a balcony or patio door, in conjunction with at least one threshold. The frame consists of extruded frame profiles that are joined together at the miter joints. This joint is typically made by welding. The frame profile has at least one base section with several hollow chambers, a rebate section, and a frame overlap, which in turn has at least one overlap hollow chamber. Each overlap hollow chamber has at least one frame overlap wall that delimits the overlap hollow chamber. Typically, the frame profile, when installed, forms part of the floor structure.

[0010] According to the invention, at least one of the frame profiles is reduced by at least a portion of the frame overlap, such that the frame overlap walls of the original frame profile are severed and at least one overlap cavity is open on the side facing away from the foot area. The at least one threshold is interlocked with at least one frame overlap wall and at least one open overlap cavity.

[0011] Since the threshold is only used in a portion of a frame profile, the advantage is that the typically welded corners remain untouched, allowing for the same building waterproofing as with a conventional frame. Because the threshold does not extend continuously from the inside to the outside, the on-site waterproofing can be applied as required, without a step or weak points, horizontally at the bottom and laterally upwards. Furthermore, all lateral details (waterproofing, sun protection, etc.) can be implemented as usual.

[0012] Advantageous configurations result from the characteristics of the dependent claims.

[0013] According to a preferred embodiment of the invention, the threshold has at least one groove suitable for locking into a frame overlap. This is achieved, for example, by making the threshold thin-walled to allow for limited elastic deformation. The groove preferably has a width that, at its narrowest point, is slightly less than the wall thickness of the frame overlap. Thus, when the frame overlap is pressed in, the groove widens slightly, allowing the frame overlap to be inserted into the groove; the groove then presses against the frame overlap due to elastic deformation and holds it securely.

[0014] It is advantageous if the threshold is supported on the outer side of the building frame profile. This creates an additional connection between the threshold and the frame profile, in which the threshold presses against the frame profile.

[0015] The threshold can also be supported in the overlap of the frame profile.

[0016] To enable drainage, drainage openings can optionally be provided from the fold area, penetrating at least one overlapping hollow chamber.

[0017] If the threshold has continuous threshold openings in the area that covers at least one overlapping hollow chamber and / or the fold area, water can flow through these threshold openings into the overlapping hollow chamber and / or the fold area and then flow into the surroundings via drainage openings.

[0018] If the threshold covers the drainage openings on the outside of the building's frame profile with a gap, the result is a pleasing exterior appearance and the drainage is protected from environmental influences.

[0019] The invention further provides a door created with a frame according to the invention in combination with a correspondingly adapted door leaf. The door leaf consists of extruded sash frame profiles which – like the frame profiles – are joined together at the miter joint.

[0020] The sash frame profiles preferably include, among other things, a rebate area designed to accommodate glazing or a panel, and a sash frame overlap. When the door is closed, the sash frame overlap vertically at least part of the frame.

[0021] The sash frame overlap has at least one hollow chamber with at least one enclosing sash frame overlap wall on the side facing away from the rebate area.

[0022] By optionally removing at least one of these sash frame overlap walls, or at least one hollow chamber in the area adjacent to the threshold when the door is closed, a hollow chamber is completely or partially removed. If the hollow chamber is only partially removed, the remaining partial hollow chamber can optionally be sealed with a cover. This allows the door leaf to extend further down towards the threshold, thus reducing the gap between the threshold and the door leaf. The door leaf height must be adjusted accordingly in this case. This option is preferably only suitable if the seal between the sash and frame is not attached in the removed area.

[0023] In the inventive method for manufacturing a frame for a door, preferably a balcony or patio door, with at least one threshold, wherein the frame consists of extruded frame profiles which are joined together in the mitered area, wherein the frame profile has at least a foot area with several hollow chambers, a rebate area and a frame overlap with at least one overlap hollow chamber, at least one of the frame profiles is reduced by at least a portion of the frame overlap, preferably by sawing or milling, so that the frame overlap walls of the original frame profile are cut and at least one overlap hollow chamber is open on the side facing away from the foot area. At least one threshold is then interlocked with at least one frame overlap wall and at least one open overlap hollow chamber. Brief description of the drawing

[0025] The same reference symbols in different figures have the same meaning. Not all reference symbols are shown in all figures.

[0026] Figure 1 Figure 1 shows a section of a door 2, which is usually a balcony or patio door. The door 2 has a frame 1 and a door leaf 9. The frame 1 consists of extruded PVC frame profiles 4, which are joined together at the miter joint 8. However, the invention is also applicable to aluminum frame profiles. A threshold 3 is connected to the bottommost frame profile 4.

[0027] Figure 2Figure 1 shows the structure of the frame profile 4. This has a base area 5 with several hollow chambers 10, 11, a rebate area 6 and a frame overlap 7 with an overlap hollow chamber 11. The overlap hollow chamber 11 has frame overlap walls 12. A metallic reinforcing profile 25 is arranged in a central, large hollow chamber 10.

[0028] Figure 3 The frame profile 4 shows Figure 2 with a reduced overlap cavity 11, for which the two frame overlap walls 12 are cut through at the same height level. The overlap cavity 11 is thus open on the side facing away from the foot area 5.

[0029] Figure 4 shows threshold 3 in a three-dimensional view; Figure 5 The same threshold 3 in side view. Threshold 3 is usually an extruded aluminum part; Figure 5Figure 1 shows the view in the extrusion direction. The threshold 3 has grooves 15 which can be locked into the reduced frame overlap walls 12. The threshold 3 has grooves 18 and subsequently milled continuous threshold openings 17 in these grooves 18 on the upper surface in the area which, in the assembled state shown in the following figures, covers the overlap cavity 11 and the rebate area 6 up to the center seal. A side surface 19 is arranged perpendicular to the area with the grooves 18.

[0030] In Figure 6The frame profile 4 has a reduced overlap cavity 11 and an attached sill 3. The sill 3 is interlocked with the right-hand frame overlap wall 12 of the open overlap cavity 11. For this purpose, the sill 3 has a groove 15. Since the sill 3 is made of thin-walled aluminum, it can deform elastically to a limited extent. The groove 15 has a width that, at its narrowest point, is slightly less than the wall thickness of the frame overlap wall 12. Thus, when the frame overlap wall 12 is pressed into the groove 15, it widens slightly, allowing the frame overlap wall 12 to be inserted into the groove 15. Due to the elastic deformation, the groove 15 then presses against the frame overlap wall 12 and holds it securely in place. The threshold 3 is supported on the outside of the building 16 on the frame profile 4 with a surface and in the frame overlap 7 with a spacer lug 20.This engages the threshold 3 with the frame profile 4. The threshold 3 extends over the frame overlap 7 to a central seal in the rebate area 6. The threshold 3 rests there with its spacer lug 20 in the area of ​​the frame overlap 7 on the frame profile 4 on the side facing away from the building exterior 16. This ensures that when the threshold 3 is stepped on, the force is predominantly transferred as pressure to the frame profile 4.

[0031] Between the frame overlap 7 and the overlap cavity 11, a drainage bore 24 is located in the frame overlap wall 12. A second drainage bore 24 is located in the second frame overlap wall 12 of the overlap cavity 11, allowing water flow W to drain into the surrounding area on the exterior of the building 16. The side surface 19 of the threshold 3 covers the drainage opening 24 on the exterior of the building 16 of the frame profile 4 by a distance, thus protecting the drainage opening 24 from environmental influences. Water that collects in the grooves 18 of the threshold 3 can therefore be directed from the grooves 18 of the threshold 3 through the threshold openings 17 into the frame overlap 7 and the overlap cavity 11, and subsequently discharged into the surrounding area via the drainage openings 24 of the overlap cavity 11. The drainage does not affect the tightness of the frame 1.The threshold 3 is firmly connected to the frame profile 4 via the connection with the spacer lug 20 on the side facing away from the building exterior 16 and the groove 15 with a frame overlap wall 12. Under normal load from footsteps on the threshold 3, it cannot come loose.

[0032] Figure 7 Figure 1 shows a cross-section through the lower area of ​​the door 2 with the frame 1 according to the invention, including the threshold 3, in conjunction with the door leaf 9; this has the usual construction familiar to those skilled in the art, which will not be discussed in detail here. The door leaf 9 has a sash profile 21 similar to the frame profile 4. When the door 2 is installed, a sash overlap 22 with sash overlap walls 23 is located at the horizontal height of the threshold 3.

[0033] Figure 8Figure 1 shows a section through a lower frame profile 4 of a frame 1 1 with a view to a frame profile 4 perpendicular to it. Behind the threshold 3 is a cover cap 13.

[0034] Figure 9 shows a 3-dimensional view of the frame 1 with threshold 3 with threshold openings 17 and cover cap 13 next to the threshold 3 near the miter area 8.

[0035] Figure 10 shows a 3-dimensional view of the frame 1 without threshold 3. Where at Figure 9 Where the cover cap 13 can be seen, a profile opening 26 is located through the cut in the frame profile 4. Figure 11 shows the section in the frame profile 4 with the cover cap 13, which conceals the profile opening 26.

[0036] To manufacture the frame 1, a conventional frame is first produced from four frame profiles 4. The frame profiles 4 are first cut at a miter and welded together in the mitered area 8.

[0037] Then, on the frame profile 4, which is intended for positioning on the floor, part of the frame overlap 7 is sawn or milled away. This leaves the overlap cavity 11 open on the side facing away from the base area 5. The two frame overlap walls 12 now project vertically upwards in parallel.

[0038] The threshold 3 is positioned against the frame profile 4 with the spacer lug 20 and then centrally engaged in the groove 15 in the right frame overlap wall 12. On both sides of the threshold 3, there is a profile opening 26 in the frame profile 4 leading to the surroundings; these two profile openings 26 are each closed with a cover flap 13.

[0039] One advantage of the invention is that the threshold 3 can also be easily retrofitted or replaced. While a conventional door threshold requires extensive disassembly, a threshold 3 according to the invention – for example, if it is damaged – can be removed from the frame profile 4 and replaced with a new threshold 3.

[0040] The invention is not limited to the exemplary embodiment shown.

[0041] In particular, the invention is not limited to the profile geometry shown, but can be applied to all hollow chamber geometries made of all possible materials.

[0042] The door can be combined wholly or partially with aluminum profiles or frames. The profile can also be colored foil-wrapped, coated, or painted.

[0043] The invention also facilitates building waterproofing, in which the part of the frame positioned at ground level and the lowest lateral decimeters are separately sealed from the environment to prevent moisture ingress. Since the weld in the miter area remains unaffected, the building waterproofing can be carried out on a flat, impermeable substrate. legend
