Closing facility

The invention relates to a closure device for the lateral border of a usable area of a balcony or terrace that can be covered with a floor covering, wherein the closure device comprises a closure profile with an anchoring leg that can be placed on the usable area and with a drainage channel which is designed or can be fixed on the closure profile in such a way that the Usable area draining water can be collected in the drainage channel and drained away.

Numerous different closing devices are known from practice with which a floor covering laid on a terrace or on a balcony can be bordered laterally. Such a lateral border not only serves to reliably fix one edge of the floor covering, or one edge of it

Floor covering elements that are arranged on the edge of the usable area, but often also an aesthetically pleasing covering of an end face of the floor covering along an edge.

Many such closure devices have a closure profile that can be arranged along a side edge of the usable area. The end profile can be used to fix and glue an often waterproof film or drainage mat along the side edge. In many cases, a The end profile is also used to laterally border the floor covering on the usable area. Most of the end profiles known from practice have an anchoring leg that can be placed on the usable surface and, for example, can be glued to the usable surface or anchored on the usable surface together with the floor covering arranged thereon. With a downwardly protruding stop leg, which is formed on the end profile, a lateral stop for the end profile can be specified on the side edge of the usable area. In addition, an upstand can protrude upwards and often vertically upwards from an end of the anchoring leg that usually protrudes beyond the side edge of the usable surface, with which a side edge of a floor covering element resting on the anchoring leg is at least partially covered, thereby forming a form-fitting lateral border of the edge of the floor covering . The upstand also forms a lateral cover, which is often designed with a flat surface, of an end face of the floor covering resting on the usable surface and the anchoring leg. With a downwardly protruding cover limb, which is designed either as a separate cover limb in addition to an upwardly protruding edging or as a downwardly protruding area of an upwardly and downwardly protruding edging, a side edge of the floor covering of a balcony or a terrace. Such a closing profile is shown and described, for example, in DE 296 06 490 U1.

A downwardly protruding cover leg can also have a fold or formation directed away from the usable surface in order to flow down laterally on the cover leg To lead water away from a side edge of the floor covering of a balcony or terrace. For example, EP 0 882 856 A2 describes such a water-draining end profile.

There are also usable areas, or laying situations of a floor covering known from practice, in which larger amounts of precipitation can fall onto the floor covering and must be discharged laterally over the lateral border of the floor covering. In the case of a balcony in particular, it should be avoided that large amounts of precipitation run off in an uncontrolled manner over a balcony edge and either trickle down on an adjacent wall surface or drip down from a lower edge of the balcony. For this purpose it is known to provide a drainage channel arranged below the floor covering on an end profile laterally bordering the floor covering, in which the water flowing off from an upper side of the floor covering can be collected and discharged. In the case of some end profiles, such a drainage channel is designed in one piece and usually projects vertically downward from the anchoring leg which is arranged horizontally and rests on the usable surface.

On the other hand, in many of the closing devices known from practice, a drainage channel is made separately and can be connected to the closing profile on site if necessary. For example, in DE 10 2013 102 587 A1 or EP 0828 037, closure devices are shown and described in which a downwardly protruding leg of the closure profile has hooks or fastening means in order to separate it to be able to hang in or fix a drainage channel that can be produced.

In order to be able to ensure reliable discharge of the sewage taken up by the drainage channel, it is often necessary for the drainage channel to have a gradient to a water outlet leading away downwards. Such a gradient can often only be specified with difficulty and with increased effort using drainage channels that can be hung into a fastening leg of an end profile. Such an installation situation is described, for example, in DE 10 2013 102 587 A1. It is therefore also known from practice that a downwardly projecting fastening leg of an end profile has a flat guide surface on which the drainage channel can be placed and fastened to it. When the terminating device is installed as intended, the drainage channel and the guide surface have vertically aligned elongated holes and recesses adapted to them, so that the drainage channel can be displaced along the elongated holes and screwed to the guide surface with a laterally directed slope. Fixing a drainage channel in this way on such an end profile is comparatively complex and, in particular, requires a high level of assembly effort for specifying the desired lateral slope.

In addition, when the drainage channel is fastened in this way, the elongated holes and the clamping elements or screws used for the fastening are regularly visible. For an aesthetically pleasing overall impression of the

Closing device must then have a separate facing the fastening areas or the entire guide surface can be provided.

It is therefore regarded as an object of the present invention to design such a terminating device in such a way that the drainage channel can, if necessary, be fixed and aligned in a simple manner on the terminating profile in order to have a desired gradient. In addition, an aesthetically pleasing lateral edging of the usable area should optionally be made possible in a simple manner.

According to the invention, this object is achieved in that the drainage channel and the end profile are connected to one another via at least one rod-shaped fastening element, a fastening element seat and a receiving section being formed on the drainage channel and the closing profile in such a way that the positively fixed in the fastening element seat and in the receiving section positively fixed fastening element causes a height-adjustable fixing of the drainage channel on the end profile. The rod-shaped fastening element can, for example, be a rod with a corrugated or otherwise profiled outer surface, wherein the corrugated or profiled outer surface can come into positive engagement with an inner surface of the receiving section that is adapted to it. For a height adjustment, the receiving section can, for example, surround the lateral surface in different positions along the axial direction and be fixed in a latching manner. The positive engagement of the three-dimensionally structured jacket surface with the surrounding receiving section can advantageously be designed in such a way that an axial displacement of the Receiving section along the axial direction of the rod-shaped fastening element is possible manually and without a separate tool, but the drainage channel is fixed sufficiently firmly to the end profile at the desired height or at the desired distance from the anchoring leg.

In order to be able to arrange the drainage channel as close as possible to a side edge of a balcony or terrace, it is optionally provided that the screw thread section is arranged on the drainage channel in such a way that a fastening screw extending through the screw thread section protrudes into an interior of the drainage channel. In this case, the drainage channel expediently has a sufficiently large depth, which is measured from a bottom of the drainage channel to an upper edge of a side wall of the drainage channel, so that the fastening screw can essentially penetrate completely into the interior of the drainage channel and a maximum height adjustment of the drainage channel relative to the final profile is possible.

According to an advantageous embodiment of the

According to the invention, it is provided that the end profile has a guide leg protruding from the anchoring leg and parallel to the alignment of the fastening screw connecting the end profile with the drainage channel, on which the drainage channel rests and is guided. One side wall of the

The guide leg can form a contact surface for the drainage channel, so that the drainage channel is independent of a distance from the anchoring leg that is predetermined on site in each individual case and also independently of one individually specified slope rest on the guide leg and can thus be reliably fixed on the end profile. A flat design of the contact surface of the guide leg enables a simple and stepless height adjustment of the drainage channel relative to the end profile, which is independent of the design of an edge area of the subsurface on which the end profile rests. In addition, the guide leg can form an aesthetically pleasing veneer for a transition area between the end profile and the drainage channel.

With regard to an aesthetically particularly attractive design of the terminating device, it is optionally provided that the rod-shaped fastening element is arranged in a gap between the guide leg and a side wall of the drainage channel. The rod-shaped one

As a result, the fastening element can protrude into the interior of the drainage channel, invisible from the outside. In an assembled state of the terminating device, only one end face of the terminating profile and a downwardly protruding guide leg and the drainage channel fixed on the terminating profile are visible, while all the fastening elements provided and the respective

Fastening element seats and receiving sections, which are required for fastening the drainage channel to the end profile, are completely covered by the guide leg and can therefore be invisible to a viewer. The guide leg also does not hinder the insertion of the rod-shaped fastening element, which is aligned parallel to the guide leg and its Fastener seat is not covered by the guide leg.

It can expediently also be provided that the guide leg protrudes into an interior space of the drainage channel.

The rod-shaped fastening element can then be arranged in a narrow space between the guide leg and a side wall of the drainage channel facing the usable surface, with the guide leg also being able to cover the rod-shaped fastening element with such a configuration and thereby create a visually appealing overall impression.

In order to facilitate the most reliable installation of the drainage channel on the end profile, one embodiment of the inventive concept provides that a stop for the drainage channel guided on the guide leg is formed at an end of the guide leg protruding from the anchoring leg. The drainage channel can therefore only be arranged in a height-adjustable manner in an area specified by the guide leg, this area being specified at one end by a stop of the drainage channel on the anchoring leg of the end profile and limited at the end of the guide leg protruding from the anchoring leg by the stop formed there will. In this way, it can be avoided that an excessively large distance between the drainage channel and the anchoring leg of the end profile can inadvertently be specified during assembly or during a height adjustment process and the drainage channel can be moved by further displacement of the receiving section along the rod-shaped fastening element detaches from the end profile and could fall down.

According to a particularly advantageous embodiment of the inventive concept, it is provided that the rod-shaped fastening element is a fastening screw, and that the receiving section has a screw thread section adapted to the fastening screw. The drainage channel and the end profile are connected to one another via at least one fastening screw, a screw seat and a screw thread section being formed on the drainage channel and the end profile in such a way that the fastening screw fixed in the screw seat and screwed into the screw thread section provides a height-adjustable attachment of the drainage channel to the end profile causes. The fastening screw is expediently aligned vertically and in any case not parallel to the anchoring leg, so that by turning the fastening screw fixed in the screw seat, the screw thread section engaged with the fastening screw changes its distance from the anchoring leg and thereby changes the distance between the drainage channel and the anchoring leg accordingly can be. The drainage channel is expediently fixed to the end profile with two fastening screws, the two fastening screws being spaced apart from one another along the end profile. In the case of long drainage channels in particular, the drainage channel can also be fixed to the end profile with more than two fastening screws. For each fastening screw, the distance between the screw seat and that along the fastening screw can then be used displaceable screw thread section can be specified individually. By specifying this distance differently for the two fastening screws, a different distance between the drainage channel and the anchoring leg of the end profile can be set for two areas that are spaced apart from one another, and thereby a slope of the drainage channel can be specified.

It is conceivable that a drainage channel is composed of several rigid drainage channel segments along a larger balcony or terrace. Appropriately, each individual gutter segment is then fixed to the end profile with two fastening elements or fixing screws, so that an individual height-adjustable fixation on the end profile and an individually predeterminable gradient can be set for each gutter segment.

For the height-adjustable fixing of the drainage channel on the end profile, it is only necessary that the receiving section can be displaced along a longitudinal axis of a rod-shaped fastening element or along an alignment of the fastening screw relative to the fastening element seat or screw seat. It is basically possible either to arrange the fastening element seat on the end profile and to provide the drainage channel with a receiving section and to be able to move it relative to the end profile via the fastening element fixed in the fastening element seat of the end profile, or to form the fastener seat on the drainage channel and the receiving section to train on the final profile, so that by shifting the fastening element relative to the receiving section along the longitudinal axis of the fastening element, the fastening element fixed in the fastening element seat on the drainage channel can be shifted together with the drainage channel relative to the end profile.

With the conventional adjustment options, in which the drainage channel and the end profile are fixed to one another via clamping screws or clamp fastenings, which are guided through elongated holes, a complex manual alignment of the drainage channel relative to the end profile is necessary before a clamping fixation. In contrast to this, with the connection according to the invention of the drainage channel to the end profile by the fastening elements arranged according to the invention, a simple height adjustment of the drainage channel already connected to the end profile can be carried out by either shifting the rod-shaped fastening element relative to the receiving section or rotating the fastening screw in the screw thread section. Manual alignment and holding the drainage channel in the desired alignment is not required. As a result, the on-site installation effort can be considerably reduced and a reliable specification of a desired slope for the drainage channel can be made easier.

According to an advantageous embodiment of the

According to the invention, it is provided that the drainage channel has a screw thread section in an upper edge area and a recess for receiving the fastening screw in the anchoring leg of the end profile is designed so that the fastening screw extends through the recess in the end profile into the screw thread section of the drainage channel and the fastening screw is accessible and can be rotated from a side of the end profile opposite the drainage channel. With such an arrangement of the fastening screw, it is easily accessible from an upper side of the end profile. The drainage channel can be fixed in a simple manner to the end profile and then aligned by suitable and individual rotation of the individual fastening screws, or provided with the desired slope. The desired floor covering can then be laid on the top of the end profile. The fastening screw can be covered by an overlying floor covering element in order to enable an aesthetically particularly appealing overall impression of the end profile, in which no fastening screws are visible.

In order to facilitate a reliable arrangement of the end profile along the side edge of the usable area, it is optionally provided that the end profile has a stop leg protruding from the anchoring leg at an angle, which forms a lateral stop for a peripheral edge of a substrate. Furthermore, it can also optionally be provided that the end profile at one end of the anchoring leg has an upstand which protrudes at an angle from the anchoring leg and with which an end face of a floor covering element resting on the anchoring leg can be at least partially bordered. In terms of the most beneficial

Drainage properties, it is provided according to an advantageous embodiment of the inventive concept that passage openings are formed in the anchoring leg adjacent to the edging through which water or moisture can pass into the drainage channel arranged below. The anchoring leg can optionally have a slope that slopes down towards the upstand in a section adjoining the upwardly projecting upstand, in which the passage openings are arranged. As a result, between an area of the anchoring leg resting on the usable area of the balcony or terrace on the one hand and the upstand on the other hand, a somewhat deeper drainage channel is formed in which rainwater hitting the usable area from above or moisture emerging from the floor covering collects and passes through the passage openings can flow into the drainage channel. The passage openings can, however, also be formed exclusively or additionally in the upstand, or can extend into the upstand.

According to an optional embodiment, it can be expedient that the passage openings are arranged adjacent to the guide leg in the anchoring leg and water passing through the passage openings can flow down the side of the guide leg and get into the drainage channel. In this way it can be avoided that the water passing through the passage openings first collects at a lower region of an opening edge of a passage opening and then has to drip down. The arrangement of the Through openings adjoining the guide leg, the water passing through can flow down the side of the guide leg, which promotes reliable drainage and prevents otherwise forced dripping. In this way, especially in the case of larger amounts of water, which for example hit the usable area due to precipitation and have to be drained, or in strong winds, the drops forming at the passage openings can drip down in an uncontrolled manner and possibly cannot be caught by the drainage channel.

Furthermore, according to an advantageous embodiment of the inventive concept, it is possible that a receiving opening of the drainage channel is covered with a water-permeable cover. The drainage channel can be designed, for example, as a beveled or continuously curved U-profile. A receiving opening of the drainage channel delimited by the leg ends of the profile can be covered by a perforated plate or an attachable attachment, the attachment having a frame and a water-permeable cover element arranged in the frame. The frame can be clipped or clipped onto one leg end or both leg ends. It is also conceivable that one leg end of the U-profile-shaped drainage channel is bevelled and bent over in such a way that the receiving opening of the drainage channel is partially or essentially completely covered with the bent section. This folded area can have water-permeable recesses, holes or slots, which can expediently be introduced into the subsequently folded section of the leg end before a deformation process.

FIG. 6 shows a sectional view of a receiving section with a screw thread section and part of a fastening screw, and FIG

FIG. 7 shows a sectional view of a receiving section with part of a rod-shaped fastening element with a corrugated, profiled outer surface. In FIGS. 1 to 5, various configurations of a terminating device 1 according to the invention for the lateral border of a usable area 2 of a balcony or terrace are shown schematically by way of example. The terminating device 1 has a terminating profile 3 with an anchoring leg 4 which, when the terminating profile 3 is arranged as intended on an edge region of a subsurface 5 of the usable area 2, rests horizontally on the subsurface 5 and extends from an edge 6 of the subsurface 5 into the usable area 2 extends. The anchoring leg 4 serves to anchor the end profile 3 on the edge area of the subsurface 5. A floor covering is laid on the usable surface 2, which is composed of individual floor covering elements 7. In the edge area, the floor covering elements 7 also rest on the anchoring leg 4 resting on the substrate 5 and cover it.

At one end of the anchoring leg 4 protruding beyond the edge region of the substrate 5, the end profile 3 has an upwardly protruding edge 8. The upstand 8 is expediently dimensioned in such a way that an end face 9 of the adjoining floor covering elements 7 is covered by the upstand 8. The upstand 8 forms a form-fitting delimitation and border of the floor covering elements 7 and thus for the floor covering 6 laid on the subsurface 5 of the usable area 2.

In a region 10 adjoining the upstand 8, the anchoring leg 4 has a downward gradient towards the upstand 8. This is along the The strip-shaped area 10 extending upwardly forms a channel which is lower relative to the anchoring leg 4. This channel can also be formed by a groove-shaped depression. In this area 10, a number of passage openings 11 are arranged along the upstand 8 at a distance from one another. Rainwater that hits a surface of the floor covering and flows down over the end face 9 as well as any moisture drops that collect below the floor covering elements 7 and emerge laterally on the end face 9 are first collected in the channel and can then flow down through the passage openings 11. This promotes drainage and dehumidification of the floor covering on the usable area 2.

The end profile 3 shown in FIG. 1 has, at a distance from the edge 6 of the substrate 5, a guide leg 12 extending downward from the horizontally extending anchoring leg 4. A screw seat 14 is formed between a stop leg 13 which projects downward from the anchoring leg 4 and rests on the edge 6 of the substrate 5, and the guide leg 12. A fastening screw 15 is rotatably mounted in this screw seat 14. A drainage channel 16 is fixed to the fastening screw 15 and is fastened to the end profile 3 below the anchoring leg 4 and thus also below the floor covering and the passage openings 11. With the drainage channel 16, a controlled lateral discharge of the water flowing down or dripping down through the passage openings 11 is effected. The drainage channel 16 has an essentially U-shaped collecting profile with a drainage channel bottom 17 and two side legs 18, 19 which are arranged opposite one another and project upwards from the drainage channel bottom 17 and which form two side walls of the drainage channel 16.

On the side of the drainage channel 16 facing the subsurface 5, a screw thread section 20 is fastened or formed on the side leg 19. The fastening screw 15 is screwed into the screw thread section 20 and is in engagement with the screw thread section 20. By turning the fastening screw 15, the fastening screw 15 mounted in the screw seat 14 is not displaced along the axial direction predetermined by its axis of rotation. However, when the fastening screw 15 is rotated, the screw thread section 20 of the screw thread section 20, which is in engagement therewith, of the drainage channel 16, which is mounted on the end profile 3 in a rotationally fixed manner via two or more spaced apart from one another, shifts in the axial direction, so that the distance between the drainage channel 16 and the horizontally extending anchoring leg is shifted 4 changed accordingly. In this way, by turning the fastening screw 15, the distance between the drainage channel 16 relative to the floor covering and the cover leg 8 can be adjusted and specified within a range predetermined by a usable thread length of the fastening screw 15.

The one arranged on the drainage channel 16

Screw thread section 20 has a flat guide surface 21 which, when the drainage channel 16 is properly installed, rests on a contact surface 22 of guide leg 12 facing screw thread section 20. The guide leg 12 thereby forms a forced guidance for the screw thread section 20, which can be displaced in the axial direction along the fastening screw 15, and consequently also for the drainage channel 16. The guide leg 12 has at its lower end protruding from the anchoring leg 4 a laterally protruding stop 23 which an axial displacement of the screw thread section 20 and thus the drainage channel 16 beyond the area delimited by this stop 23 is prevented.

The guide leg 12 protrudes into an interior space 24 of the drainage channel 16. The fastening screw 15 is arranged in a narrow area between the guide leg 12 and the side leg 19 facing the substrate 5 and is covered by the guide leg 12 from an outside observer.

An end region 25 of the side leg 18 facing away from the substrate 5 of the balcony or terrace is beveled such that the end region 25 forms a water-permeable cover 26 that largely covers the interior space 24 of the drainage channel 16. Numerous openings 27 are formed in this cover 26, through which the water dripping down through the passage openings 11 can penetrate into the interior 24 of the drainage channel 16 and can be discharged therein. Undesired soiling of the drainage channel 16 by larger dirt particles or by, for example, leaves falling onto the drainage channel 16 can be prevented with the water-permeable cover 26. In the embodiment of a closing device 1 according to the invention shown in FIG. 2, the downwardly protruding guide leg 12 simultaneously forms a lateral stop for the edge 6 of the substrate 5, which is why no additional stop leg 13 is formed protruding from the anchoring leg 4. On the guide leg 12 is on which of the

Anchoring leg 4 protruding end of the screw seat 14 is formed. The fastening screw 15 is fixed to the screw seat 14 so that it cannot be displaced in the axial direction by a lock nut 27 that is fastened non-rotatably to the fastening screw 15, but is rotatable. On the side leg 19 facing the substrate 5, the screw thread section 20 is arranged on an outside facing the balcony or terrace. By turning the fastening screw 15 accessible from below, the screw thread section 20 engaged therewith and thus the drainage channel 16 can be adjusted relative to the end profile 3 in height or in the distance to the anchoring leg 4. In this exemplary embodiment, too, the planar contact surface 22 of the guide leg 12 forms a positive guide for the guide surface 21 of the screw thread section 20.

In the exemplary embodiment shown in FIG. 3, the fastening screw 15, which can be inserted into a screw seat 14, has a slot 29 at an opposite screw end 28 so that the fastening screw 15 can be rotated with a suitable tool brought in from below, which is brought into engagement with the slot 29 is. The side leg 19 facing the substrate 5 lies flat on the flat contact surface 22 of the guide leg 12, so that the drainage channel 16 is positively guided in a height adjustment on the contact surface 22 of the guide leg 12. A cover 26 is clipped onto a leg end 30 of the side leg 18 facing away from the substrate 5. The cover 26 has a water-permeable network 32 braced in a circumferential frame 31 of the cover, with which undesired contamination of the interior 24 of the drainage channel 16 can be prevented.

In FIG. 4, a side view of a terminating device 1 according to the invention is shown merely by way of example and schematically, which is arranged along a peripheral edge 6 of a substrate 5 of a usable area 2 of a balcony or terrace, which is concealed by the terminating device 1 in this view. From this side, when the terminating device 1 is installed, only the upwardly protruding edging 8, the downwardly protruding guide leg 12 and the drainage channel 16 attached to the terminating profile 3 or the side leg 18 of the drainage channel 16 facing the viewer are visible.

The fastening screws 15, shown in dashed lines for clarification, are arranged on a rear side of the guide leg 12 facing away from the viewer and are covered by the guide leg 12. The drainage channel 16 is composed, merely as an example, of two drainage channel segments 33 merging into one another and has a gradient that slopes down to the right in the illustration according to FIG. 4 along the edge 6.

In the exemplary embodiment shown in FIG. 5, the end profile 3 has none upstand protruding from the top. On such an end profile 3, floor covering edge elements 34 with a downwardly curved edge area can be laid along a side edge of the usable area. Such a closing profile 3 regularly serves to glue and thereby fix a film-like seal 35 arranged between the substrate 5 and the floor covering elements 7 and 34 on an upper side of the anchoring leg 4 or below it.

The downwardly protruding stop leg 13 is arranged directly next to the fastening screw 15 and forms a lateral forced guidance for the fastening screw 15, whereby the stability of the terminating device 1 is additionally increased and improved during assembly.

At a distance from the leg end 30 of the side leg 18 facing away from the substrate 5, the drainage channel 16 has two inwardly directed formations 36 on opposite inner side regions of the side legs 18, 19. These formations 36 form a support for a strip-shaped, water-permeable cover 26, which can optionally be inserted into the drainage channel 16.

In FIG. 6, a lower end 37 of a self-tapping fastening screw 15 and a receiving section 20 adapted to it with undulating inner surfaces 38 are shown by way of example. The self-tapping fastening screw 15 can penetrate a connection area 39 while it is being screwed into the receiving section 20. In FIG. 7, as an example of a fastening element 40 that is not a fastening screw, a rod-shaped fastening element 40 with a corrugated outer surface 41 is shown. The receiving section 42 adapted to it likewise has undulating inner surfaces 43. The rod-shaped fastening element 40 can be fixed in various positions along the longitudinal direction of the rod-shaped fastening element 40 in the receiving section 42, the corrugated lateral surface 41 engaging with the corrugated inner surfaces 43 of the receiving section 42 in a form-fitting manner. The receiving section 42 is deformable so that the rod-shaped fastening element 40 can be displaced in the receiving section 42 along the longitudinal direction, but is reliably fixed and fixed in the desired position.
