Abstract

The beam has an interface provided connection of an extension (3) for increasing total width of the beam, where the interface faces an outer area. A seal and/or a seal arrangement i.e. seal cushion, seals an intermediate space between a lower edge of a wing of a window or a door and the beam in a closed condition of the window or door. An adapter (2) is connectable to the interface. The adapter is designed as a separate connecting unit, which detachably/fixedly interconnects the beam and the extension, where the beam, the adapter and the extension are formed from aluminum.

Description

The invention relates to a threshold for a window or a door, wherein the threshold separates an interior of a building from an exterior or two spaces and the threshold the gap between the lower edge of the wing of the window or the door and the threshold in the closed state of the window or the door seals in cooperation with at least one seal or seal assembly.

Such thresholds are known. They become, for example in the manufacture of window or door elements on the frame or frame of the window or door already factory mounted. In contrast to conventional windows, where the frame is made four-sided closed and the lower part is installed in the installation direction in the ground, now reinforced sleepers are used, which are designed as barrier-free thresholds. This means that these thresholds no longer have a substantial increase over the finished floor in the final state. The proposed by the applicant for this threshold extends a maximum of up to 3 mm on the finished floor in a slightly curved arc, so that even wheelchairs, walkers or hospital beds can drive over it easily, without being hindered. The Applicant has already submitted a number of corresponding pre-applications, which describe the subject of such a threshold in cooperation with the frame of a window or with the door leaf of a door. These pre-registrations are explicitly referred to. In particular, the applicant has filed for barrier-free transitions thresholds that meet all requirements for such barrier-free transitions and also have a tested tightness against wind pressure and driving rain.

In modern buildings, such as residential buildings or commercial buildings in the low energy sector, it has recently been noted that the existing insulation in the ground, which extends below the threshold, according to the latest calculations must be further improved to even here the heat transfer even further minimize. The heat transfer is meant, for example, from the outside inwards. For this there is no technical solution that ensures in particular the secure placement of such insulation outdoors in the floor or soil. Here is, for example, the possible crushing or deformation meant the Dämmmaterials by too high loads.

Often it is nowadays also the case that on the outwardly facing sides of the threshold, for example on balconies or terraces, a splash or rainwater drainage channel is provided, which must be covered with appropriate grates. Auch.hier it is necessary, in addition to the insulating properties of the threshold to the outside area, also to take into account that a tight connection to such a channel must be guaranteed. For this reason, a solution is often required that allows a dense, but easy connection to the threshold, so no complex sealing work on site must be performed on site.

Based on the above-described prior art, it is an object of the invention to develop a threshold, which makes it possible on the outwardly facing side of the threshold at least one supplementary element, for example, a secure cover another, additional Dämmmaterialschicht or a locking receptacle before To exclude ground threshold.

The object of the invention is achieved by a threshold for a window or a door, wherein the threshold separates an interior of a building from an exterior or two rooms and the floor threshold the space between the lower edge of the wing of the window or the door and the threshold in the closed state of the window or the door in cooperation with at least one seal or sealing arrangement seals, which is characterized in that at the bottom threshold facing at least to the outside an interface for connection of a supplementary element is provided. By such a supplementary element, it is now possible to connect, for example, an extension to increase the overall width of the threshold, in order to arrange an additional layer of insulating material in front of the threshold, that is to say towards the outer area, and to arrange such that it is not crushed by the pressure of the overlying floor or by corresponding loads. The extension is to be understood that this increases the total depth of the threshold in the direction of the building or away from the building. In this case, such an extension may be provided with corresponding support means which prevent crushing of the insulating layer to the substructure. The solution according to the invention, it is of course now possible to provide as a supplementary element, for example, a grate holder, which is provided as an insert in a splash or rainwater drainage channel on terraces, balconies or the like. The provision of the interface for the connection of this grate holder makes it possible to attach or clasp them in a simple manner, for example to the threshold. A seal is then only necessary in the form of the introduction of sealing material or adhesive in or on the interface. This will be described later. This ensures a safe drainage of rainwater or spray water, which drips off the door or window element, into the rainwater or spray water drainage channel.

The interface allows a connection of an extension in different widths, each resulting from the calculation of the necessary Dämmmaterialdicke and / or - width or layer. Now it is possible to provide a neat and clean finish, and in particular a conclusion that avoids deformations or destruction of the insulating material layer and continue to provide in particular a barrier-free transition from an indoor area to an outdoor area of a building or between two rooms. Such a solution could For example, be used in a door that separates a cold room or cooled or air conditioning room, for example, from a normal temperature room. Here, too, higher insulation values for the heat transfer between indoor and outdoor areas must be taken into account. The invention is also suitable for this purpose in an excellent manner.

As already mentioned above, the interface also makes it possible, of course, to connect a grate holder in different widths instead of the extension in different widths. It will be based on the system widths of the manufacturer of such Spritzwasserbeziehungsweise rainwater drainage channels, as these are usually provided on prefabricated concrete elements. Of course, such a grate holder can also be inserted into a splash or rainwater drainage channel, which was made on site so to speak in monolithic process or masonry. The connection is made to the already mentioned interface, which allows a releasably fixed connection. Thus, a later replacement, in the case of damage, for example, is possible.

Advantageously, the invention proposes in a refinement that an adapter is provided at the interface and / or the adapter can be connected to the interface. Included in this is also an embodiment in which the adapter forms the interface. This means that a total of three technical options are described in this embodiment: on the one hand, that an adapter is provided at the interface, that is at the threshold or at the connection point of the extension or the grate receptacle to the threshold. The adapter can be provided either on the extension or the grate holder and / or be formed; he can also provided according to the invention at the threshold and / or be molded. Furthermore, it is possible to form an adapter as an independent connection means, which, so to speak, as an intermediate piece, the ground sill and the extension or the grate receptacle releasably connected together. Thus, the threshold according to the invention is universally applicable and in particular so variable that can cover very different Dämmmaterialbreiten with an extension accordingly. In particular, the accessibility is still ensured, since both adapter and extension or grate receptacle are connected to the threshold so that a transition is created, which provides no resistance for rolling objects, such as wheelchairs, rollators or hospital beds.

According to a development of the invention and a corresponding variant of the solutions described above, it is possible that the extension at least with the insertion position of the ground sill side facing in the adapter insertion or can be inserted. This is meant for the case that no adapter is arranged on the extension itself, so that the solution now described is adapted to an adapter which is located directly on the ground sill, or in an adapter, as an intermediate piece or as independent connection means is designed to be used.

For this purpose, the adapter according to the invention also has a preferably U-shaped receptacle. The recording is designed so that the extension is inserted there easily. The opening of the U then corresponds to the material thickness of the extension. Here, a small game is certainly complied with, but in such a way that after installation or after the attachment of the threshold no movement is possible here. Optionally, a sealing seam with silicone at the end of the U can be provided, or you can add Put some silicone or sealant in the U before inserting the extension. Here, the invention is not limited to a particular embodiment, but includes several of the previously described options.

A threshold, as previously described, is characterized according to an advantageous embodiment in that the receptacle is formed by an upper leg and a lower leg. It is advantageously provided so that the lower leg is shorter than the upper leg and in the direction of the opening of the U has a taper or bevel. As a result, the insertion of the extension into the U is greatly improved. Thus, it is achieved by the taper or bevel that you can easily insert this by slightly Ankanten extension in the U, even if this is designed to be very narrow to prevent the previously described unwanted rattling or moving within the U-shaped receptacle. It is also advantageous if the upper leg and the lower leg are connected to each other by a web to form or complete the U-shaped receptacle.

It is further advantageous if, facing the threshold, a nose is formed or provided on the upper leg of the U-shaped receptacle in the installation direction, which preferably has a shape corresponding to the threshold on the connection in order to ensure a seamless transition. This is done in particular in order to avoid a paragraph even at the connection point of the extension at the threshold. This is achieved by providing the described nose. At the junction between the threshold and adapter or extension with adapter a sealant is inserted according to the installation guidelines of the Applicant to the ingress of moisture from Exclude in the first place. Already the mutually corresponding shape of bottom sill and adapter or extension to the connection of the two to each other, ensures a moisture-repellent solution. The introduction of sealant completes this result only.

The threshold is further characterized in that it is provided in an advantageous variant that, starting from the web in the installed position of the threshold facing, angled connection is provided. This connection is particularly suitable for receiving certain connection or fastening means that allow a simple and fast connection between the adapter and the threshold or extension of the threshold. Thus, a further aspect is specified by the fact that the connecting element is arranged at an angle of approximately 90 ° to the connection, so possibly even by this configuration, a strip-like configuration is formed, whereby it is possible, this "bar" in corresponding grooves in to let the threshold intervene, for example.

It is advantageous in this case if the connecting element preferably has differently shaped ends on both sides, which in the mounted state engages in grooves provided correspondingly at the bottom sleeper. For a very simple connection of adapter with threshold or extension with the threshold is readily possible. It is also advantageous if the variant described above is distinguished by the fact that the end or the ends are designed for a clip connection. Thus, both sides can be designed for a typical clip connection, which are seen in cross section by a knob-like design. Of course, it is also possible according to the invention that only the side facing the ground or to the ground threshold (ie in the installed position upwards) facing Side have such a configuration. This makes it possible to connect the extension with a very convenient way of connection, namely by clipping together.

In order to enable such a clip connection, it is provided in one embodiment of the invention to provide at the threshold, at least on the side facing the interface, a clip into which engage the ends of the adapter in the connected state of bottom sleeper and adapter. Of course, another embodiment is included as a bracket-like embodiment of the invention with. However, this is preferred because of the elegant and material-saving design.

According to the invention it has also been found that it is advantageous if the supplementary element for connection to the ground threshold for connection to the interface in installation direction from above obliquely or angled with the connecting element to the groove can be applied and by pivoting in the direction of the bottom of the connecting element with the groove detachable / firmly connectable. It is particularly focused on the clip connection described above, since the threshold according to the invention is characterized in that when the interface is designed as a clip connection, namely the extension element, the extension or the grate mount obliquely applied to the outer side and with the connecting element the interface is created. By pressing down, that is, by pivoting in the direction of the bottom of the clip connection is then clipped. Such a compound is particularly advantageous because it is not only easy to produce, but it is also easily solvable. This means that in case of repair work on the insulating material layer, the extension can easily be lifted out again. The same is to be recorded for the Rostaufnahme, the can also be removed again for maintenance and / or repair work from the threshold, without material destruction occurs here.

The invention is further characterized by the fact that on the outwardly facing side of the extension, a further interface is provided on either a further extension designed as a broadening, for example as Überbückungsprofil or the grate holder is releasably firmly connected. This makes it possible to arrange in the low-energy house area an additional insulating layer in front of the threshold in the ground, cover it with an extension according to the system, as described, and then connect a grate receptacle, which is able to absorb the spray or rainwater. Thus, a clever system is available to provide even in low energy house appealing solutions, especially barrier-free.

The further interface is particularly preferably designed analogously to the first interface. Thus, the individual elements for extension or completion of the threshold are universally interchangeable. It is clear that the previously described advantages of using different widths of the extension or the grate holder can also be used in this embodiment.

The threshold of the applicant is already characterized in previous solutions of the prior art without a connection possibility of an extension in that it has at least one Höhenverstell- or Höheneinstellvorrichtung. The invention now proposes in a development that a Höhenverstell- or Höheneinstellvorrichtung is provided both at the threshold and in particular on the extension. That's it now possible to adjust both the threshold in their setting to the desired finished size before completing the floor and then fix with the frame in the building, as well as the extension. The extension will be adjusted in particular to a slight slope, starting from the junction at the threshold, in order to avoid drainage of rainwater or moisture here as well.

The invention also includes a solution in which the extension is cut to the desired width by conventional means, for example by a circular saw with a metal circular saw blade. This can be done with millimeter accuracy.

In order to facilitate the placement of an extension, it is provided according to the invention that a receiving channel formed from struts is provided for receiving the height adjustment device. This is preferably U-shaped with a groove and can therefore easily accommodate, for example, a suitably trained nut receiving a set screw or a screw, which can be secured with a locknut, if necessary, after setting. It is of advantage, of course, if this height adjustment device is likewise formed from a material which conducts the heat poorly, for example plastic or a plastic composite material.

As already mentioned, the threshold is particularly suitable for producing barrier-free transitions between the interior and the exterior of a building or between two rooms.

According to the invention, it has also been found that it is advantageous if the grate receptacle is U-shaped in the installed position as an upwardly open U. Thus, a gutter is provided in addition, so to speak, which take up the rust can. It is of course also possible that the grate receiving downwards at least partially has openings through which incoming moisture or water can be dissipated in the on-site drainage channel. If you do not want this in particular to avoid the moisture in the soil in this area, you can of course form the grate recording closed and then equip them with appropriate processes or lines that can be initiated in a drainage or in a sewer system. Such an embodiment is also included in the invention.

The configuration of the grate holder may be different according to the invention. Thus, on the one hand, it can be pulled as a single profile piece, which has the connection means for connection to the interface. However, the grate receptacle can also be formed from individual elements, which is formed for example by a bottom plate and two lateral end elements. In this case, the bottom plate is inserted into the lateral end elements, such that, for example, corresponding receptacles for the bottom plate are present in the Abschlußaselementen. Of course, it is also provided according to the invention that in the grate holder a corresponding grate can be inserted. These grates are already manufactured by different system suppliers and are therefore available on the market. The grate holder according to the invention is accordingly made so that the grates there are easily and in particular ropeless, that is barrier-free, can be inserted.

Also on the grate mount according to the invention corresponding connection connections are provided to connect at least one further height adjustment device, but preferably also two or more height adjustment devices. About the width of the grate mount these Höhenverstelleinrichtungen be arranged both parallel to each other and each with offset from each other. This offset can be chosen so that tilting or tilting the grate holder is no longer possible.

A further embodiment of the invention is characterized in that at least the closing element facing the ground sill or the widening itself is designed as a connection adapter. The broadening according to the invention may also be designed as a bridging profile. This is a preferred embodiment, which is offered in particular by the Applicant. The Anschussadapter can now be used in place of a firmly provided on the grate support connection connection by fulfilling two tasks, namely on the one hand the completion of the locking receptacle and on the other the connection with the possibility of connecting the interface to the threshold or at the widening.

As already mentioned, a receptacle or a gap is provided on the connecting element or on the connecting element designed as a connecting element, which is formed by two legs. In this space, the bottom plate of the grate holder can be inserted, in particular fastened. For this example, the gap may be slightly conical, so that you can attach the bottom plate with light pressure. You can of course also gluing or sealing.

It is also advantageous if provided on the connecting element as a connection element connecting element to the one or more interfaces of corresponding connecting elements, which are in particular formed analogous to that provided on the adapter described earlier adapter. This creates the opportunity to make a system provision, the system will be described later becomes.

The speed bump according to the invention is characterized in a further development by the fact that at the outwardly facing in the installed position connecting element at least one bend as a support on the floor and / or at least one downward pointing to Spritzwasser- or rainwater drainage extension legs, the attachment in or on the ground serves. A further embodiment of the invention proposes an end angle, which is provided as an end angle for the splash water or rainwater drainage channel cover.

It is also advantageous if the threshold has at least one magnetic seal, at least as part of a sealing arrangement with further seals that seal the gap between the lower sash of the sash and the sill in the closed state of the door or the window. Of course, the threshold according to the invention is not limited to the presence of a magnetic seal. Rather, a refinement with sealing cushions, sealing lips or the like arranged on the lower frame parts of the window sash or of the door leaf is also encompassed by the invention.

The threshold or the supplementary element (s), the adapter and the extension and grate holder are advantageously made of light metal, preferably made of aluminum. In this case, at least one thermal separation, preferably at least in the threshold, preferably 2 to 3 thermal separations provided in order to hinder or prevent the heat transfer through the threshold.

The invention also provides a supplemental element for connection to a bump as previously described. This is this Supplementary element designed as an extension or as a bridging profile or as a grate holder. Of course, both supplementary elements can be produced in different widths and / or can be adapted accordingly to different widths in the on-site preparation.

The invention also provides a widening and / or insulating system with at least one threshold of a grate receptacle and an extension as previously described, comprising at least two insulating material layers provided below the threshold and the extension, in particular for window and door elements of a low energy building, wherein the Insulation system seals the area in the ground between a window or door element to the outside and at least one each Höheneinstell- or - adjusting the threshold and extension. In order for a total of a very universal system is provided, the insulation of the critical area of the connection of the building to a door or a French window now better than in the prior art known.

The invention also provides a broadening and / or insulating system, which is designed as a modular system. This modular system consists of at least one threshold, at least one extension or a bridging profile, a grate holder, wherein extension and grate receiving are provided as supplementary elements for the threshold. Furthermore, the widening and / or insulating system comprises at least one height adjustment device, preferably one height adjustment device on one of the supplementary elements, at least one adapter or a termination element designed as a connection adapter and at least one in particular prefabricated substructure insulation with molded-in receivers for the height adjustment device. Such a broadening and / or insulating system allows a wide variety of Requirement to be provided by the customer. This will be further clarified in the embodiments.

In the drawing, the invention is shown schematically in particular in an embodiment example.

In the figures, the same or corresponding elements are each denoted by the same reference numerals and will therefore not be described again, if not appropriate.

The Fig. 1a and 1b show a first embodiment of the inventive threshold 1. In Fig. 1a is the threshold 1 in the installed state with extension 30 as supplementary element 3 and corresponding insulation layers 6, 7, 8, 10 shown. Above the threshold 1, the wing 11 of a window or door element is shown. It is only the lower wing frame, in cooperation with a seal assembly 12, consisting of a sliding seal 13, two magnetic seals 12/1, 12/2 and an additional inner seal 14, the space between the lower sash and the bottom sill. 1 seals. Below the threshold 1 here several insulation layers 7, 10 are designated. Immediately below the threshold 1 is the insulating layer 7. This may for example be designed as a prefabricated substructure insulation according to the system of the applicant, described in an earlier application. Facing the interior area II, a further insulation layer 8 is provided below a screed layer 9. At the conclusion of the threshold 1 to the interior II, there is another continuous insulation layer 10. The Höhenverstell- or -einstellvorrichtung 4, by means of which the threshold 1 can be fixed in its final height before it is fixed together with the window frame in the building, is shown here as an adjusting screw with a nut guided in a groove. A lock nut serves to fix the height once set.

In the direction of the outside area I is below the extension 30, the additional insulation layer 6, which is particularly necessary for buildings in the low energy range. In order to connect the extension 30 to the threshold 1, an interface A according to the invention is provided. At the Interface A is in accordance with the variant shown Fig. 1a and 1b an adapter 2 is provided. The adapter 2 is once connected to the ground sill 1 and has on the other to the extension 30 side facing a U-shaped receptacle 20. The U-shaped receptacle 20 is formed by an upper leg 22, a lower leg 21 and a web 26th The extension 30 can be inserted into the U-shaped receptacle 20. On the side facing the threshold 1, the adapter 2, starting from the web 26, has a connection 23 which, at its end facing the bottom sleeper 1, carries a connecting element 24 which is like a bar or in section, like a pin or bolt. The connecting element 24 is arranged at an angle of approximately 90 ° to the connection 23. On both sides, that is towards the threshold 1 pointing upwards or pointing to the ground downwards, differently shaped ends 24/1, 24/2 are provided, which engage in the assembled state in correspondingly provided on the ground sill 1 grooves. The ground sill 1 has, as can be seen, a bracket 15, in which the ends 24/1, 24/2 of the adapter 2 in the connected state of the bottom sill 1 and adapter 2 in there existing, unspecified grooves intervene. The bracket 15 is also preferably formed over the entire width of the bottom sill 1. At the interface A or at the junction of the adapter 2 with the bottom sill 1, a sealant B is introduced. These may be commonly used sealants for sealing in structures such as silicone or the like. Also in the groove 20 formed as a receptacle 20 of the adapter 2 is inventively provided to introduce a sealant to prevent ingress of moisture.

The adapter 2 has formed on its side facing the ground sill 1 side a nose 25, which has a corresponding to the bottom sill 1 at the port shape to an ansatzlosen Ensure transition. Furthermore, the adapter 2 has at its side facing the extension 30 a chamfer, which also ensure a nearly hitchless transition to the extension in the installed state. Advantageously, the extension 30 also has a height adjustment or - setting device 5. This serves to fix the end of the extension 30 in the intended installation state and support. As a result, for example, the additional insulating layer 6 can no longer be deformed, since 5 such loads can be absorbed by the Höheneinstell- or -verstelleinrichtung. Preferably, of course, the Höheneinstellvorrichtungen 4 and 5 are formed from a poor thermal conductivity material.

In the Fig. 1b the extension 30 is shown in a slightly larger representation. It can be seen that a receiving channel 500 formed by struts 33, 34 is provided for receiving the height adjustment or adjusting device 5.

This has a groove-like recess, so that there, for example, as in Fig. 1a it can be seen, a nut can be inserted, whereby the screw of the height adjustment 5 can then be adjusted accordingly. Below can then be secured with a locknut as usual. The invention provides for adaptation to different widths of the extension that they are provided in sufficient width and the extensions 30 are adjustable by means of normal mechanical processing, such as sawing to the desired width.

In Fig. 1c an embodiment of the invention the bottom sill 1 is shown in which the extension 30 of the adapter 2 is already formed. This adapter 2 engages provided in the bottom threshold 1 wells, which are formed for example in the manner of a clip connection. Between the Threshold 1 and the extension 30 is, as in the previously described embodiments, a sealant B, such as silicone, introduced. In the Fig. 1c Threshold 1 shown here is provided for an embodiment of a lifting / sliding door, which as a seal assembly 12 here, so-called sealing pad has. Below the threshold 1 here, for example, widening profiles 7/1, 7/2 clipped, which also represent an insulating layer due to their cavities. Furthermore, an insulating material layer 7 is also provided below the floor sill 1. All other reference numerals have already been presented and are used in the same way again. A renewed presentation is therefore omitted.

The Fig. 2a and 2b show in side view a threshold with extension and connection adapter according to the invention. The extension bears the reference numeral 30. This is clipped with an adapter 2 on the bottom sill 1. The extension 30 has on the side facing the outside also an interface C, which is here formed for example by a receiving groove 1/3 and on the closing element 50, which is designed here as a connection adapter, provided connection means, namely a strut 53, which is the connecting element 54 carries with the two ends 54/1 and 54/2. These engage in the receiving groove 1/3 or in there provided grooves, which were not specified. The end member 50 has two legs 51 and 52 which receive the bottom plate 43 of the grate holder 40. This is only shown in sections. In the Fig. 2b In a detail view, a part of the extension 30 is shown, on the receiving groove 1/3 here a closing element 50 is shown, which is formed, for example, as a rectilinear downwardly pointing legs, for example, hineinzuragen in a gutter receiving. The rust would then be placed in the rainwater drainage channel.

The Fig. 3 shows an embodiment of the inventive threshold with an extension 30 as a supplementary element 3 and a grate holder 40 as a supplementary element 3. In the grate holder 40 while a grate 46 is inserted. The interface on the extension 30 again bears the reference character C. A sealant B can of course also be introduced at this interface. However, this is not shown here. Below the extension 30 an unspecified further insulation layer is shown. Through this layer of insulation passes through the drainage line, which optionally derived incoming sweat and / or rainwater from the seal assembly of the threshold is derived. This can, as can be seen in the also unspecified rainwater drainage channel are performed.

The Fig. 4a to 4e show further embodiments of the invention threshold with different combination options. Thus, in this embodiment, at the threshold according to the invention and the interface A a grate holder 40 is arranged, which receives the grate 46. As can be seen, Höheneinstell- or -verstellvorrichtungen 4/1, 5/1 are also provided here, which wear the grate recording safe and shake-free. In the Fig. 4b and 4c It can be seen how the grate holder 40 is attached according to the invention at the interface A, for example. For this purpose, the grate holder 40 is made slightly at an angle and then stirred into the groove 1/2. After the engagement of the upper connecting element 54/2 then the grate holder 40 can be pivoted to the horizontal position. As a result, the lower connection element 54/1 also snaps into the groove 1/2 or the recesses or grooves present there, thereby forming a detachably fixed connection. This is the principle of a clip connection and has the advantage that in addition to a configuration such that a slight connection option is created, also a possibility exists, the grate holder quite easy to solve again from the threshold, for example for repair purposes. Also on the end element 50, a nose 50/1 is formed, which, as can be seen, in the connected state allows an abrupt transition to the threshold. If the grid is then inserted, a barrier-free transition, as generally produced by the applicant, is obtained. At the grate holder 40 more height adjustment 4/1 and 5/1 are arranged, which intervene in existing connection options 44, 45. The outer end forms the closing element 55th

In the Fig. 4d and 4e is shown in a plan view and a side view of the grate mount according to the invention. In this case, all reference numerals have already been presented, so that even here can be dispensed with a new idea. In Fig. 4e left end 56 is still shown, which is provided for the splashing or rainwater drainage channel cover. This end angle can be used together with the grate holder 40 or independently thereof as the end angle.

The Fig. 5a and 5b show a further embodiment of details of the grate holder. In the Fig. 5a Here, an angled 55/1 is shown as a support on the floor on the outer end member 55. This serves the safe and also barrier-free transition to the ground, for example to a terrace or a balcony. In the Fig. 5b is on the outer end member 55, an extension leg 55/2 shown, which serves the attachment in the relationship or at the bottom. For this purpose, for example, a bore provided provided relationship, then in the corresponding connecting means can be introduced into the soil. Advantageously, this is done by using, for example, through dowel and then screwing a screw.
