EP1932997A2 - Upper closure of a threshold, closure system and threshold - Google Patents

Abstract

The upper end (44) of a sill has a locking device which consists either of a locking leg (50) arranged on the end facing away from the door stop side and lockable in a locking slot (54) arranged in the weather strip (12) or in a hollow profile (14), or between the weather strip and hollow profile, or consists of a locking device (52) which in use is located against the door stop wall of the hollow profile, or consists of both the locking leg and the locking device. An independent claim is included for a locking system for a sill in which a section of a locking component is brought to bear at least partially on the end of the weather strip pointing towards the door side and aligning with the outside contours of a locking strip.

Description

The invention relates to a top of a threshold, which threshold of a metal or made of plastic weathershaft and thus latched in use on the door side, forming a thermal break hollow profile, the conclusion as Arretierungsleiste in use on a door stop side of the hollow section and at least partially attachable to a door-side end of the weatherboard and connectable by means of at least one latching device with the hollow profile.

Such a degree is for example from the EP 1 270 861 A2 known. The disclosed there threshold of a door has a so-called abutment element free lid, which rests on both the abutment wall of the thermal separation producing plastic hollow profile, as well as a portion of the door to the door stop wall facing edge of the weatherboard edge rests.

This cover has a problem in that it essentially bridges a large, deep and wide groove in the hollow profile. Due to the two outboard supports but he can yield in the direction of this cavity, which is not always desirable. On the other hand, this cover leads to the problem of being able to bring closure elements for Türverriegelungspilzapfen only with great difficulty. In this prior art, the space for the closure elements on the hollow profile area must be milled out.

The invention is therefore based on the object of specifying an upper termination or a locking strip of the aforementioned type, which eliminates the problems arising from the prior art, thus allowing greater stability and at the same time substantially simplifies the introduction of closure elements and thus made more cost-effective.

This object is achieved with a locking bar of the type mentioned in the present invention that the locking device consists either of a detent web, which is disposed on the end remote from the door stop side and latched into a arranged in the weatherboard or the hollow profile or between the weatherboard and the hollow profile locking groove is, or consists of a latching device which is arranged in the use of the Türanschlagswand of the hollow profile, or consists of the latching web and the latching device, and by a wall portion which forms a part of the Türanschlagswand in use, and by at least one hollow chamber between the support points ,

The essence of the invention is to increase by the additional detent web the supporting area for the locking bar and thus the force transmitted thereby. A further increase in the absorbable deflection load is further increased by the additionally arranged at least one hollow chamber, since thereby the cross-sectional area of the locking strip is increased. Finally, the wall section also ensures that a locking element, if necessary, can have such a height and thickness that ensures a firm and burglar-proof locking of the door or window sash.

According to one embodiment of the invention, it is provided that the latching device consists of a web or two opposing webs, which are each provided with hook-shaped tips.

Thus, a better seal between locking bar and the other threshold elements in the transition area between the hollow profile and weatherboard is facilitated, it is advantageous if in use the partial support is formed at the door-side end of the weatherboard by a section of the part of the weatherboard Forming a water rupture edge is continued.

This can be ensured even easier if, in use, the complete support at the door-side end of the weatherboard is formed by an edge whose free end forms a broken edge of water.

In addition, however, it can also be advantageously provided that the section has a seal on at least one area which can be brought into contact with the weatherboard.

There are certainly a variety of possible connections of the locking bar with the locking groove. However, it is particularly advantageous if the latching web can be fastened in the latching groove via a hook-shaped end or via a plurality of teeth, wherein the majority of the teeth are arranged either on the latching web or in the latching groove.

Thus, the locking strip according to the invention does not cancel the thermal separation, it should consist of an at least difficult heat conductive material. It is particularly advantageous if the locking strip is made of plastic.

According to one embodiment of the invention, it is provided that the locking bar in the use state to the door facing end of the weatherboard has a transverse direction to the weatherboard and the hollow profile projection.

It is particularly advantageous if the locking strip forms a locking system with a locking part. This locking system consists advantageously of a locking strip, as well as a locking part, which is used in a rebate of the threshold so that at least a portion of the locking part in use on the door facing the end of the weatherboard at least partially be brought to rest and essentially with the outer contours of Arretierungsleise aligned.

The advantage consists in providing on the locking part a projection which rests in use on the weatherboard at least partially. Thus, it is usually unnecessary, between the weather leg around the Locking provided at this point an additional seal.

An increase in this above-mentioned simple sealing effect is advantageously given by the fact that the portion is formed as an edge for breaking water; that the end of the corresponding edge projects beyond the weatherboard.

If the edge is made of plastic and forms an overlapping sealing lip, can be dispensed with the additional introduction of a seal in this area.

There are various ways to design a locking part. It is particularly advantageous if the closing part consists of a box-shaped body which receives a metal or / and resistant material existing plate having at least one recess which is capable of receiving a locking element of a door or window in use.

It is then of particular advantage if the body made of plastic coated with metal and the plate made of steel, stainless steel, glass fiber reinforced plastic or the like.

A reduction in the manufacturing cost of the locking member is possible when the body is designed to accommodate commercially available plates.

According to one embodiment of the invention, it is provided that the plate is riveted to the box-shaped body, screwed, clipped or glued.

An aesthetically pleasing design is possible if the plate is the top or the top and covering the side facing away from the weatherboard in use state. The second alternative also has the advantage that a slip of a role is supported at this point. For example, a wheel or a wheel has wheelchairs.

If the box-shaped body is made of metal, it is possible to design the plastic that surrounds it made of hard or soft plastic. While the hard plastic is used for the thermal separation, it is particularly advantageous in the second alternative, the use of soft plastic as a cladding material, to use this soft plastic at the same time as a seal against the other parts.

According to a development of the invention, it is advantageously provided that sealing devices are arranged on the end faces and / or on the side facing the weathershank in the use state.

There are a variety of ways to enter the locking part in the rebate of the threshold. But it is particularly advantageous if the locking part can be clamped in the rebate, clipped, screwed.

In many cases, a seal is not necessary. However, if a seal is necessary, it is particularly advantageous if formations for receiving sealing devices are formed on the side surfaces.

A particularly adaptable form of a sealing device is given if it is designed as a sealing star.

Of course, it is possible if the door or the window is open, which can enter into the region of the locking part moisture, through the recesses for receiving the mushroom pin. But then it is particularly advantageous if venting channels are formed on the side facing the hollow profile in use.

So that the threshold on the outside door can better prevent the water from entering when it rains, it is advantageous if, in use, the surface or tread surface is at least partially inclined to the weatherboard.

Against ingress of water due to so-called driving rain, it is particularly advantageous when in use on the top at the transition to the weatherboard at least one sealing element is present, which extends in the longitudinal direction.

A further embodiment provides that a web or detent web pointing in the vicinity of the section in use to the threshold is arranged, which can be connected or latched to one of the two or both threshold elements. This embodiment increases the fastening force and coincides with the locking web of the locking strip according to the invention.

However, the above object is also achieved according to the invention by a threshold system consisting of a closing part for a made of a metallic weather struts and thus latched in use on the door side, forming a thermal break forming hollow profile threshold, with a locking strip and a locking part according to one of corresponding subclaims.

Further features and advantages of the invention will become apparent from the following description of a plurality of embodiments and from the figures, to which reference is made.

Based on FIGS. 1 to 36 Now several embodiments of a locking strip of a locking system and a threshold with the locking elements according to the invention are described in more detail.

First, based on the FIGS. 32a-i to 36 refer to various embodiments of a locking bar 44 reference. It should be noted that in all described Arretierungsleisten 44 a locking device for connection to a hollow section 14 of a latching web 50 and a latching device 52, both of which are described below. However, this latching device can also consist of the latching web 50 or the latching device 52. This is not shown in the drawings.

The FIGS. 32 a to i show six different locking strips 44 and a locking part 10. While at all FIGS. 32a to i an identically formed hollow section 14 is used, while the associated metal or plastic weatherboard 12 are substantially identical, but with the exception of the transition between the locking bar 44 and the weatherboard 12th

Both FIGS. 32b, c, e and f the resting on the corresponding part of the weatherboard 12 part of the locking bar 44 is formed by a portion 20 '. This portion 20 'is continued by a portion of the weatherboard 12 to form a broken edge of water.

In contrast, in the FIGS. 32a and b the transition from an edge 20 a formed, the free end itself forms the water break edge.

Each of the in the FIGS. 32a to f Locking strips shown has two hollow chambers 64 which are closed. In this case, a hollow chamber 64 in the vicinity of the door stop wall of the hollow profile 12 and is bounded on this side by a wall portion 56. This wall section 56 extends the door stop side of the entire threshold profile.

In the in the FIGS. 32a to d shown locking bars 44, the wall portion 56 goes over in a rounded shape to the upper side of the locking bar 44 via. In contrast, the Arretierungsleisten 44 according to the FIGS. 32e and f formed so that the wall portions 56 is aligned substantially transverse to the top of the Arretierungsleisten 44.

Below each arranged at the wall portion 56 hollow chamber 64, a latching device 52 is formed on the locking bar 44, which then engages in a corresponding receiving groove, which is not specified.

These locking devices 52 may consist of either a web with a hook-shaped tip or two opposing webs with corresponding hook tips.

Between the hollow chamber 64 at the wall section 56 and the area resting on the weatherboard 12, a further hollow chamber 64 is arranged in all the locking strips 44 described herein. Both hollow chambers 64 increase not only the thermal separation, but also the cross-sectional area of the locking bar 44 and thus offer greater resistance to forces from above.

In the in the FIGS. 32a to i Arretierungsleisten shown 44 and Arretierungsteil 10 are at the transition region between the hollow section 14 and the weatherboard 12 in use state facing these locking webs 50 available. These have in the too Figure 32 af all the same cross-sectional shape and engage, as shown, in this case in a locking groove 54 which is formed on the hollow profile 14 facing the end of the weatherboard 12. The in the FIGS. 32a to f shown locking grooves 54 are provided with teeth 62, which serve a better clamping action for the locking bar 50. But it is also possible, which is not shown in the figures, to provide these teeth also on the locking webs 50. Although only in the FIGS. 32e and f between the sections 20 'and the weatherboard 12 seals 58 are shown, it is of course possible, these seals 58 with the rest in FIG. 32 applied embodiments shown.

Both Fig. 32a-f and i the locking grooves 54 are formed by corresponding parts of the weather strip 12. But it is also possible, as in the Fig. 32g and h to see the locking groove 54 provided between corresponding walls of the weatherboard 12 and the hollow section 14 in the region of the transition between the two profiles. Otherwise apply to the embodiments according to the Figures 32g and h the same explanations as they have already been given above and will follow in the following.

Regarding the Fig. 32i is to say that here the locking bar 44 have a special feature to the effect that in the region of the transition from the weatherboard to the hollow profile 14 is a transverse thereto and away from it bead or a projection 44a is present. This projection 44a serves primarily as a stop for an unspecified in Figure 32i illustrated door.

For easier understanding of the corresponding arrangements according to the FIGS. 32a to f is in the FIG. 33 the embodiment according to Fig.32a shown in individual parts.

Based on Fig.34 is recognizable as, in this case, the embodiment according to Fig.32a , the locking bar 44 is positioned in the installed state with the door closed.

It is off Fig.34 also still be removed that the entire threshold 16 can still be placed on a distance profile 66 for height compensation. Of course, this spacer profile 66 could also have such a width that even in the state of use down facing hollow chambers of the weatherboard 12 could also be locked with connecting parts with the spacer profile 66.

The Fig.35 shows the cross section through a threshold with a locking bar 44, which is substantially similar to that according to FIG Fig.32b is.

The only difference here is that the latching web 50 still has a hook-shaped end which can be taken with a corresponding projection within the locking groove 54, which is in this case in the weatherboard 12.

Finally shows the Fig.36 a possibility of locking the locking bar 44 with the threshold elements, in which case the locking groove 54 is formed in the hollow section 14. Otherwise, this locking bar 44 shows the edge 20'a according to Fig.32a , Also, the locking bar 50 according to Fig.36 has a hook-shaped end, but in this case one of the embodiment according to Fig.35 has opposite direction.

With reference to the FIGS. 1 to 31 Now, various embodiments of a closing part or a locking part 10 will be described in more detail.

All closing parts or locking parts 10 are intended for a made of a metallic or plastic weathershed 12 and thus latched in use on the door side, forming a thermal separation hollow section 14 existing threshold 16. Such thresholds are in the FIGS. 8 . 9 . 14 . 15 . 17 . 18 . 20 . 21 and 22 at least partially shown.

In this case, the locking part 10 in a rebate 18 of the threshold 16 can be used such that at least one portion 20 can be brought to rest on the door facing the end of the weatherboard 12. This section 20 is several times in the Fig.23 to 31 represented, in which case a water break edge of the weatherboard 12 must be formed. This will be further described below. An even simpler way of producing the desired seal described above is given when this section 20 is completely formed as an edge 20a for breaking water. This is in all FIGS. 1 to 22 as shown.

In Fig. 1 an embodiment of the locking part 10 is shown, which consists of a box-shaped body 22, the upwardly facing opening is covered by the plate 24. This plate 24 has at least one recess 26, which receives a locking element 28 of a door or window 30 in use. In Fig.1 an existing plastic edge 20a is shown, which overlaps in the use state for this locking part 10 facing end portion of the weatherboard 12.

The Fig.2 shows essentially the embodiment according to Fig. 1 However, although there the plate 24 is made of a hard material core, such as metal or glass fiber reinforced plastic, and is coated with a plastic. Furthermore, the in use state from above to be seen end edges of the locking part 10 are provided with a sealing device 32 which seals the transition to a locking bar 44, which will be described later.

In Figure 3 is in addition to the embodiment of Fig.2 also shown a sealing star 36, which rests in use on the weatherboard 12. This increases the seal between weatherboard 12 and locking part 10th

While the embodiments according to the FIGS. 1 to 3 has a rounded in use state to the door side facing area is in Figure 4 an embodiment shown in which the box-shaped body 22 also indicates a wall in the door region and therefore also supports the plate 24 there.

The Figure 5 shows the embodiment according to Figure 4 only with a sealing star 36 already described above.

In both embodiments according to Figure 4 and 5 sealing devices 32a are still provided on the end faces, which can be used instead of the sealing strip 32 already described above or in addition thereto.

In Figure 6 is a combination of the embodiments according to the 2 to 5 shown. Here, in addition to the sealing device 32a, the linear sealing device 32 is also added.

The Fig. 7 shows a locking member 10, wherein the box-shaped body 22 is formed substantially as a plate portion and the plate 24 engages the body 22 in such a bridge-shaped that seen in the longitudinal direction, the two ends of the locking member 10 are not covered by the plate 24. In addition, this embodiment also has two recesses 26 for receiving a locking element 28, which are formed opposite one another, starting from the free ends of the plate 24 to the center of the plate 24.

In Figure 8 two views of a threshold 16 are shown, namely with weatherboard 12, hollow section 14, the locking member 10 according to Fig.1 and a subsequent locking bar 44th

The Figure 9 shows in a similar way as the Figure 8 the embodiment of the locking bar 44 according to Figure 4 in the installed state as part of the threshold 16.

The Figure 10 is a cross-sectional view of the threshold 16 in the mounted state with a closed door or on a closed window 30. It is clear to see how the locking element 28 engages in the there unspecified recess 26.

The Figure 11 shows two ways to attach the locking part 10 and the locking bar 44, once with a pin not specified, which engages in an upwardly open cavity of the hollow section 14. The other possibility consists of a locking clip 46, which engages latching in the above-described hollow profile. Of course, the locking parts 10 can also be connected in other ways with the threshold elements. For example, the locking part 10 also be clamped or screwed into the rebate 18.

In Figure 12 is clearly shown that in the use state to the hollow profile 14 facing side of the box-shaped body 22 extending in the longitudinal direction venting channels 38 are formed. These Figure 12 shows the embodiment according to Fig.1 in which the sealing edge 20a is not yet formed.

The same applies to the Fig. 13 that the embodiment according to Figure 4 represents, in contrast to the embodiment according to Figure 12 the box-shaped body 22 has only one venting channel 38.

At the in Figure 14 In the embodiment shown, the box-shaped body 22 provided with the plate 24 is open at the end sides in the longitudinal direction. In order for this arrangement, in use, to have a sufficient seal after insertion into the sill 16 and also to contain the edge 20a, the abovementioned arrangement is received in a pocket 42 made of soft plastic. Of course, this bag 42 may also consist of a hard plastic, in which case, however, the end faces are provided with corresponding sealing devices.

While in Figure 14 this arrangement is shown in exploded view, is from the Figure 15 this arrangement recognizable in the installed state. It is also particularly clear that in use, the outer contour of the locking member 10 is substantially flush with the outer contours of the locking bar 44. This applies, moreover, for all embodiments.

The Figure 16 shows an embodiment according to Fig.2 similar embodiment. In contrast to this is above the edge 20a still provided an additional sealing element 40. For the embodiment shown, the sealing element 40 is formed in the form of a half shell and extends in the longitudinal direction over the entire length of the locking part 10.

The state of use of the embodiment according to Figure 16 is in the Figure 17 shown. It should also be noted that the locking bar 44 is also provided with a corresponding sealing element 40. In the embodiment shown, the sealing element 40 of the locking bar 44 is received in an unspecified groove. This unspecified groove serves to absorb a part of the material there under load of the sealing element 40, so that, for example, no greater resistance is exerted on a wheelchair.

Various forms of sealing elements 40 are in the Figure 18 shown. Thus, for example, in addition to the half-shell-shaped sealing element 40, it is possible to form this as a brush or a tube.

The cross-sectional view according to Figure 19 shows the embodiment according to Figure 17 when completely installed with closed door or window 30th

In the Figure 21 It is shown that the upwardly-facing surface of the locking part 10 in use may at least partially be inclined in the direction of the edge 20a. This slope helps drain rainwater or condensation. The appropriately trained locking bar 44 is in fig.20 shown.

Although the Figure 22 FIG. 3 illustrates various cross-sectional views of the locking bar 44, are the different shapes of the water-breaking edge 20a but also provided for the locking bar 44. In this case, the three enlargements of the region of the water-breaking edge 20a once show a sharp bevel, on the other hand a wedge-shaped groove and, for the third, a tooth-like closure shape in cross-section.

The FIGS. 23 to 31 describe in essence embodiments of locking members 10, partially in connection with Arretierungsleisten 44, all of which have the above-mentioned section 20 which can be brought to rest on the end of the weatherboard 12. In this case, only the lengths of the sections 20 are partially different, which, for example, from a comparison of Figures 23 and 25 is recognizable.

The particular difference to all embodiments already described, however, is that in the vicinity of the section 20 in the use state in the direction of threshold 16 facing web 50 is present. This web 50 is connected to one of the two threshold elements or even with both connectable or even latched. This leads to a substantial increase in the strength of the locking part 10 in the installed state, since an additional support in the region of the transition between the hollow section 14 and weather strip 12 is given.

Otherwise, the embodiment corresponds to Figure 23 essentially that of the Fig.1 , the embodiment according to Figure 24 essentially that of the Figure 4 , the embodiment according to Figure 25 essentially that of the Figure 13 , the embodiment according to Figure 26 essentially according to the locking part Figure 15 and the same applies to the embodiment according to Fig.27 ,

The Figure 28 shows four views of a further embodiment, although the web 50 and the section 20 shows in a somewhat elongated manner, but has a completely different shaped body 20 at least on the bottom. The downwards in use state and connectable to the hollow section 14 underside is significantly enhanced compared to the other embodiments. This is intended to be able to use this locking part 10 for higher thresholds 16.

This in Figure 29 Embodiment shown with three views is substantially in accordance with that Figure 23 match. However, the end faces on sealing elements 40, which ensure a seal against the Arretierungsleisten 44 or the frame.

Finally, the show Figures 30 and 31 the embodiments according to Figure 23 and 29 in the installed state.

Although not shown in detail in the figures, it is possible to form the body 22 in such a way that it can also serve for accommodating commercially available plates 24. Further, although not shown, it is possible to fasten, screw, clasp or glue the plate 24 to the box-shaped body.

In the invention, therefore, it is a locking part 10 which is inserted and fixed in the rebate 18 of the threshold 16.

If the locking part 10 is inserted into the threshold 16, it is flush with its upper side. Thus, when the door is closed, the door 30 results in a lesser amount of folding, see Figure 19 As a result, the sealing against driving rain is difficult, but this can be eliminated by means of the sealing elements 40.

A threshold 16 should have a maximum height of 20 mm according to DIN 18025 "Barrier-free apartments". So that this height is not exceeded with the sealing element 40, this is folded away when driving over, for example, with a wheelchair or pressed. This is already above with reference to Figure 18 been mentioned.

The sealing element 40 of the locking strip 44 can, as in Figure 17 to see, to the sealing element 40 of the locking part 10 projecting on the sides and slightly offset from the position of the sealing element 40 of the locking bar 44. As a result, both sealing element 40 can overlap in the installed state. In particular, in the case of double-leaf doors, a very good seal is achieved, which according to the current state of the art has always proved to be very problematic in conventional systems.

The threshold system according to the invention is particularly clear from the 8 to 10 . 14 . 15 . 17 and 31 , Not only with reference to these figures, the threshold system, in particular the corresponding threshold elements has been clearly described, so that a renewed description is omitted here.

It goes without saying that the individual inventive features desired in a meaningful way, can be combined with each other.
