Description

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 producing the same.

Technical area

Plastic has become established as a material for frame profiles for the production of windows and doors in many markets due to the efficient processing and longevity of the products. Plastic profiles are generally cut with a miter and welded together in the miter area to form a frame. At least for larger processors, the production of window frames and sash frames from plastic profiles is usually carried out on complex production lines in which the individual work steps are carried out one after the other. In order to enable efficient production, none of the individual work steps must last significantly longer than other work steps, otherwise the entire production line would have to be operated correspondingly slower.

For many doors, the frame has the same profile on all sides. The advantage here is that the frame can be welded in the four corners, which improves both sealing and strength. However, the problem here is that the frame at the bottom protrudes above the ground and thus creates a tripping hazard. To avoid this, door thresholds are installed on the floor instead of the frame profile installed on the other sides, especially in public buildings and in disabled-accessible living. These thresholds are usually included with the rest of the frame screwed. The tightness and drainage are relatively complex.

For sliding doors, such as those from DE 202007015160 U1 are known, the threshold must therefore be formed from different profiles than the other three sides in order to be able to accommodate the running rail.

State of the art

Out of DE 4441289 A1 A balcony or terrace door with a threshold profile rail that can be placed on the frame is known. To prevent water from entering the building, the profile rail has a water collecting channel at the transition to the frame profile. The water that collects in this gutter is drained over the sides, which requires appropriate water flow there.

DE 102004016079 A1 discloses a door in which both the sash frame and the frame are made entirely of the same profiles. In the case of a frame, the frame overlap in the threshold area is filled up by using a threshold profile. As a result, the frame in the threshold area is slightly higher than the frame alone due to the additional threshold profile.

Task

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 enables simple drainage.

Presentation of the invention

The invention solves this problem by means of a frame for a door, which is preferably a balcony or patio door, in conjunction with at least one threshold. The frame is made of extruded Frame profiles, which are connected to each other in the miter area. The connection is usually made by welding. The frame profile has at least a foot area with several hollow chambers, a rebate area and a frame overlap, which in turn has at least one overlap hollow chamber. A rollover hollow chamber has at least one frame rollover wall, which delimits the rollover hollow chamber. When assembled, a frame profile is usually part of the floor structure.

According to the invention, at least one of the frame profiles is reduced by at least a part of the frame overlap, so that the frame overlap walls of the original frame profile are severed and at least one overlap hollow chamber is open on the side facing away from the foot area. The at least one threshold is locked with at least one frame overlap wall at least one open overlap hollow chamber.

Since the threshold is only used in a partial area of a frame profile, the advantage is that the mostly welded corners remain untouched and the building can therefore be sealed in the same way as with a conventional frame. Since the threshold is not routed continuously from the inside to the outside, the on-site sealing can be routed horizontally at the bottom and upwards to the sides as required, without a step and without weak points. There is also the advantage that all side details (sealing, sun protection, etc.) can be implemented as usual.

Advantageous refinements result from the features of the dependent claims.

According to a preferred embodiment of the invention, the threshold has at least one groove which is used for locking a frame overlap wall is suitable. This is achieved, for example, by the threshold being thin-walled in order to be able to deform elastically to a limited extent. The groove preferably has a width which is slightly smaller at the narrowest point than the wall thickness of the frame overlap wall. This means that the groove is widened slightly when the frame overlap wall is pressed in, so that the frame overlap wall can be inserted into the groove; Due to the elastic deformation, the groove then presses on the frame overlap wall and holds it in place.

It is advantageous if the threshold is supported on the outside of the building by the frame profile. This creates a further connection between the threshold and the frame profile, in which the threshold presses against the frame profile.

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

In order to enable drainage, drainage openings can optionally penetrate the at least one overlap hollow chamber from the fold area.

If the threshold has continuous threshold openings in the area which covers at least one overlap hollow chamber and/or the rebate area, water can flow through these threshold openings into the overlap hollow chamber and/or the fold area and then flow into the environment via drainage openings.

If the threshold covers the drainage openings on the outside of the building of the frame profile at a distance, this results in a beautiful external appearance and the drainage is protected from environmental influences.

The invention further provides a door which is 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 connected to each other in the miter area.

The sash frame profiles preferably have, among other things, a rebate area which is intended to accommodate glazing or panels and a sash frame overlap. When the door is closed, the sash frame overlap vertically covers at least part of the frame.

The sash frame flap has at least one hollow chamber with at least one sash frame flap wall enclosing it on the side facing away from the rebate area.

By optionally removing at least one of these sash overlapping walls, at least one hollow chamber in the area which adjoins 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 closed with a lid. This allows the door leaf to protrude further down towards the threshold, so that the gap between the threshold and the door leaf can be made smaller. In this case, the door leaf height must be adjusted accordingly if necessary. This option is only suitable if the seal between the sash and frame is not attached in the remote area.

In the method according to the invention for producing a frame for a door, preferably a balcony or patio door, with at least one threshold, the frame consisting of extruded frame profiles which are connected to one another in the miter area, the frame profile having several hollow chambers at least over a foot area, a fold area and a frame overlap with at least one overlap hollow chamber, at least one of the frame profiles is reduced, preferably by sawing or milling, by at least a part of the frame overlap, so that frame overlap walls of the original frame profile are severed and at least one overlap hollow chamber is open on the side facing away from the foot area. At least one threshold is then locked with at least one frame overlap wall at least one open overlap hollow chamber.

Figure 1 shows a portion 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 connected to one another in the miter area 8. However, the invention can also be used with aluminum frame profiles. A threshold 3 is connected to the lowest frame profile 4.

Figure 2 shows the structure of the frame profile 4. This has a foot area 5 with several hollow chambers 10, 11, a rebate area 6 and a frame overlap 7 with a overlap hollow chamber 11. The one overlap hollow chamber 11 has frame overlap walls 12. In a central, large hollow chamber 10 there is a metallic reinforcement profile 25 arranged.

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

Figure 4 shows the threshold 3 in a three-dimensional view; Figure 5 the same threshold 3 in the side view. Mostly it acts The threshold 3 is an aluminum extrusion; Figure 5 shows the view in the extrusion direction. The threshold 3 has grooves 15 which can be locked with 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 top in the area which, in the assembled state, which is shown in the following figures, covers the overlap hollow chamber 11 and the fold area 6 up to the center seal. A side surface 19 is arranged perpendicular to the area with the grooves 18.

In Figure 6 is a frame profile 4 with a reduced overlap hollow chamber 11 and an attached threshold 3. The threshold 3 is locked with the right frame overlap wall 12 of the open overlap hollow chamber 11. For this purpose, the threshold 3 has a groove 15. Since the threshold 3 is made of thin-walled aluminum, it can deform elastically to a limited extent. The groove 15 has a width which is slightly smaller at the narrowest point than the wall thickness of the frame overlap wall 12. The groove 15 is therefore slightly widened when the frame overlap wall 12 is pressed in, so that the frame overlap wall 12 can be inserted into the groove 15. Due to the elastic deformation, the groove 15 then presses on the frame overlap wall 12 and holds it firmly. The threshold 3 is supported at the same time on the outside of the building 16 on the frame profile 4 with a surface and in the frame overlap 7 with a spacer nose 20. As a result, the threshold 3 is locked with the frame profile 4. The threshold 3 leads over the frame overlap 7 to a center seal in the rebate area 6. The threshold 3 lies there with the spacer nose 20 in the area of the frame overlap 7 on the frame profile 4 on the side facing away from the outside of the building 16. As a result, when entering the threshold 3, the force is transmitted predominantly as pressure to the frame profile 4.

Between the frame overlap 7 and the overlap hollow chamber 11 there is a drainage hole 24 in the frame overlap wall 12, in the second frame overlap wall 12 of the overlap hollow chamber 11 there is a second drainage hole 24, so that a water flow W can flow into the environment on the outside of the building 16 for drainage. The side surface 19 of the threshold 3 covers the drainage opening 24 on the outside of the building 16 of the frame profile 4 at a distance, so that the drainage opening 24 is protected from environmental influences. Water that collects in the grooves 18 of the threshold 3 can thus pass specifically from the grooves 18 of the threshold 3 through the threshold openings 17 into the frame overlap 7 and the overlap hollow chamber 11 and then led into the environment via the drainage openings 24 of the overlap hollow chamber 11 become. 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 nose 20 on the side facing away from the outside of the building 16 and the groove 15 with a frame overlap wall 12. Under normal stress caused by steps on threshold 3, it cannot come loose.

Figure 7 shows a cross section through the lower area of the door 2 with the frame 1 according to the invention with threshold 3 in connection with the door leaf 9; This has the usual structure that is familiar to those skilled in the art and which will not be discussed in detail here. The door leaf 9 has a sash frame profile 21 similar to the frame profile 4. When the door 2 is assembled, there is a sash frame overlap 22 with sash frame overlap walls 23 at the horizontal height of the threshold 3.

Figure 8 shows a section through a lower frame profile 4 of a frame 1 1 with a view of a frame profile 4 perpendicular thereto. There is a cover cap 13 behind the threshold 3.

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.

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

To produce the frame 1, a conventional frame is first made from four frame profiles 4. The frame profiles 4 are first mitred and welded together in the miter area 8.

Then, in the case of the frame profile 4, which is intended for positioning on the floor, part of the frame overlap 7 is sawn or milled away. As a result, the rollover hollow chamber 11 is open on the side facing away from the foot area 5. The two frame overlap walls 12 now protrude parallel and vertically upwards.

The threshold 3 is placed on the frame profile 4 with the spacer lug 20 and then snapped centrally into the right frame overlap wall 12 using the groove 15. On both sides of the threshold 3 there is then a profile opening 26 in the frame profile 4 to the surroundings; These two profile openings 26 are each closed with a cover flap 13.

An advantage of the invention is that the threshold 3 can also easily be inserted or replaced subsequently. While a conventional door threshold requires complex dismantling work, a threshold 3 according to the invention can - for example if it is damaged - from Frame profile 4 can be removed again and replaced with a new threshold 3.

The invention is not limited to the exemplary embodiment.

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.

The door can be combined in whole or in part with aluminum profiles or frames. The profile can also be colored foiled or coated or painted.

The invention also promotes building sealing, in which the part of the frame positioned on the floor and the lowest lateral decimetres are separately sealed from the environment in order to avoid the ingress of moisture. Since the welding in the miter area remains untouched, the building can be sealed on a flat, dense surface.
