Description

System for fixing a pipe

The invention relates to a system for fastening and for covering at least one line with at least one fastened to a building wall holding element. Furthermore, the invention relates to a ventilation and / or air conditioning device in a building with such a system.

For the ventilation of rooms of a building and for air conditioning, it is sometimes necessary to introduce later ventilation ducts in a building or its rooms. For this purpose, it is known to lay round tubes in a suspended ceiling or a wall cladding or to bring such pipes obscured by slitting walls and floors. However, these known solutions are on the one hand associated with a lot of effort and on the other hand, if necessary, require the presence of a suspended ceiling or wall paneling. In contrast, a surface mounting of ventilation ducts or the like. By means of clamps or the like. Holding elements for visual reasons, at best, in basements perceived as acceptable.

Object of the present invention is in contrast to provide a system for attaching at least one line and a ventilation and / or air conditioning device, which is particularly suitable for retrofitting in existing buildings and allows for low installation effort visually appealing cladding of the lines.

This object is achieved with a system for attaching at least one line substantially in that at least one fastened to a building wall holding element, which has means for releasably fixing at least one line in the holding element, and a the holding element and / or the at least one line at least partially covering the cover element is provided, which is releasably fastened to at least one hinge member on the holding element. In other words, the system according to the invention is designed so that it allows both a fixation and a cover of at least one line, for example an air duct for the supply and / or exhaust air in inhabited rooms.

The holding element provided according to the invention can be designed as an angle or the like, which is preferably fastened to a building wall in wall and / or ceiling corners by means of screws or the like. In addition, means are provided on the holding element, which allow releasably to secure at least one line. The cover member additionally provided according to the invention makes it possible to cover both the holding element and the at least one line, wherein the cover can be designed by an attractive design so that this is not bothersome.

By the hinge member on the one hand, the attachment of the at least one line is facilitated, since the cover is pivotable from a holding element and the at least one line covering position in an open mounting position. On the other hand, the line and the retaining element can be closed and covered particularly quickly by simply closing the cover element.

The holding element has according to a preferred embodiment, at least one, in particular two, approximately U-shaped receptacles each having at least one latching or retaining projection as a means for releasably fixing. In this way it is possible to insert a line, in particular a, for example, oval air duct, in the U-shaped receptacle, wherein the line is releasably fixed by a rear engagement by one or more latching projections.

In a further development of this inventive idea, it is provided that the means for releasably fixing at least one line have an inner contour adapted at least in sections to the outer contour of the line to be fastened. Thus, it is preferred if the lines are formed, for example, as oval air channels and the means for releasably fixing the conduit by more than 270 °.

For this purpose, the means for releasably fixing the at least one line are preferably formed as an elastically resilient plastic and / or metal elements, for example, clasp-like. In this way, the means for releasably fixing at least one line can form a clamping, latching, snap-in or plug-in connection, which enables rapid assembly and disassembly of lines.

The joint member is preferably arranged and formed in the system according to the invention such that the cover element is pivotable relative to the retaining element about an axis which extends at least approximately parallel to the main extension direction of the line to be fastened. The main extension direction is understood to be the longitudinal direction of the line to be fastened, in which a fluid can flow through the line. This embodiment of the hinge member makes it easy to open and close the cover in the manner of a flap to make the holding element and / or the at least one line accessible or cover.

In this case, it is preferred according to the invention if each cover element is assigned at least two retaining elements, each of which has a hinge member. The size of the holding elements in the main direction of extension of the - A -

fixing line is preferably small compared to the size of the cover and / or the line to be fastened in the main extension direction.

The cover itself can also be fastened detachably to the hinge member in particular via a clamping, latching, snap or plug connection. This makes it possible to replace the cover or to remove for maintenance, without having to dismantle the line or the retaining element to be fastened.

If the cover is detachably fastened to the holding element via an additional clamping, latching, snap or plug connection, the cover can be quickly and safely locked in its position covering the holding element and the at least one line. It is particularly preferred if the cover is attached to the hinge member via a snap or snap connection and on the side facing away from the hinge member of the support member via a latching connection is releasably fixed. The locking connections makes it possible to allow an individual fine adjustment. Thus, the cover can be used in some areas more firmly to the holding element or the at least one line, for example, to cover unevenness or gaps in the building wall.

It has proven to be particularly advantageous if the cover element can first be preassembled in a first position on the hinge member, this position allows pivoting of the cover and a good accessibility of the holding element and the line (s). The actual fixing of the cover can then take place in that the cover is moved, for example, parallel to one of the walls (or ceiling or floor) in a second position, in which the cover as possible close to the wall or the like. Is applied and preferably also can not be pivoted.

In principle, it is preferred if the system according to the invention is laid in a corner between two walls or a wall and a ceiling (or the floor). For this purpose, the holding element can have two mutually perpendicular legs or sections which can be connected to a wall, ceiling or floor surface, for example via a screw connection. These legs or sections need not completely abut the respective wall or the like, but it may be sufficient if only in the region of the U-shaped receptacles only a small contact surface is provided on the wall.

In this case, the cover element is preferably designed such that the holding element and the at least one line can be grasped concealingly by the cover element at least from two mutually perpendicular directions. In other words, the cover conceals the holding element from the directions not applied to a wall, ceiling or bottom surface. For this purpose, the cover may also consist of two, for example, right-angled legs or rounded. Furthermore, it is also possible for the cover element to extend substantially in a plane which adjoins the two mutually perpendicular legs or sections of the holding element, i. The cover extends partially in diagonal to the legs or portions of the support member.

Alternatively, however, it is also possible that the cover member surrounds the holding element and the at least one line concealing from three directions, for example by the cover is designed semicircular or U-shaped. The disassembly of the cover can be facilitated by having at least one recess for the attack of a tool between the support member or a building wall adjacent thereto and the cover. This recess may for example be formed as a groove or a depression, for example in the manner of a shadow gap. Of course, it is also possible to solve the cover without the use of a tool by manually intervening with the fingers in the recess of the cover.

In addition to the attachment of conduits, such as air ducts, the inventive system is also suitable for the simple and concealed installation of cables or the like .. For this purpose, the holding element and / or the cover is in addition to the means for releasably fixing at least one line preferably at least a cable holder equipped on which cable or the like. Can be placed or fixed on this. This holder offers the possibility to carry cables or install concealed afterwards. These may be telephone, multimedia or power cables.

Furthermore, it is provided according to a preferred embodiment of the invention that the cover element has at least one air inlet or outlet, which is preferably integrated in the cover element. Such exhaust and air inlets can be in direct flow communication with the system fixed lines, so that the system is not only the attachment of lines, but can also be used as Luftein- or outlet.

Alternatively or additionally, at least one lighting element can be integrated into the cover element. The system according to the invention can thus additionally fulfill the function of direct or indirect lighting of the building or room in which the system is installed. It is particularly preferred if the system according to the invention is constructed as a modular system in which several different types of holding elements are provided. For example, holding elements for receiving a single line as well as holding elements for receiving two or more lines can be provided. According to the invention, different covering elements are provided for each type of holding element, each of which is compatible with at least one of the holding elements, but differing, for example, in design. This makes it possible to first attach the lines to the holding elements and then subsequently to attach a design element and / or functionally individually selected cover element to the holding elements.

The invention further relates to a ventilation and / or air conditioning device in a building with at least one ventilation duct, which is releasably secured in a corner of the building with a system of the type described above and at least partially covered. The corner can be a horizontal or vertical corner of the building.

For the ventilation and the air conditioning of a building, it is particularly preferred if the device according to the invention is equipped with a fresh air line and an exhaust air line, at least partially adjacent to each other, in particular parallel to each other. In this case, the fresh air line and the exhaust air line are preferably fastened together in a system of the abovementioned type and are jointly covered by the cover element.

A particularly space-saving and visually appealing arrangement of the ventilation and / or air conditioning device can be achieved in that the at least one ventilation duct has a substantially oval cross-section. The system according to the invention or the ventilation and / or air conditioning device according to the invention is particularly suitable for use in a ventilation system or in a method for equipping a building with a ventilation system according to DE 10 2008 011 348, to which reference is made in its entirety.

The invention will be explained in more detail by means of embodiments and with reference to the drawings.

14 and 15, the disassembly of the system of FIG. 1st

The system for fastening lines shown in FIGS. 1 and 5 to 15 essentially has a retaining element 1 and a cover element 2. As can be seen particularly clearly from the view of FIG. 6, the holding element 1 is designed so that it can be mounted with two legs or sections in a corner between two schematically indicated walls of a room via screws 3. For this purpose, 1 recesses in the holding element. 4 formed, in which the head of mounting screws 3 can be accommodated.

Furthermore, the holding element 1 has means for releasably fixing two lines 5A and 5B, which in the illustrated embodiment are designed as air channels, for example a supply air channel and an exhaust air channel, with a substantially oval cross section. The means for releasably fixing the lines 5A and 5B are designed as U-shaped receptacles 6A and 6B, which are formed integrally with the holding element 1.

The receptacles 6A and 6B of the retaining element 1 have an inner contour which is adapted to the oval outer contour of the lines 5A and 5B. In this case, latching projections 7A, 7B and 7C are provided which engage behind the lines 5A and 5B in order to fix them in the holding element. The leads 5A and 5B are thus fixed in the manner of a snap connection in the U-shaped receptacles 6A and 6B of the retaining element 1. In this case, the U-shaped receptacle 6A or 6B encloses the respective line 5A or 5B by more than 270 °.

On the retaining element 1, a hinge-like joint member 8 is further hen, which is pivotable about an axis parallel to the two wall surfaces on which the holding element 1 is fixed. In other words, the pivot axis of the joint member 8 runs approximately parallel to the main extension direction of the lines 5A and 5B. As can be seen from the enlarged illustration of FIG. 9, the articulated member has a mouth-like opening with latching teeth for connecting the cover element 2 on the side facing away from the retaining element 1.

For this purpose, the cover element 2, which in the illustrated embodiment is approximately configured as a quadrant, has a fastening tab 9 with a thickened end which adjoins the inner contour of the mouth-like opening. tion of the joint member 8 is adapted such that the cover 2 in the joint member 8 can be latched. As will be explained below, however, the cover element 2 can also be detached again from the joint member 8. On the upper right side in FIG. 6, the holding element 1 has a latching toothing 10, by way of which the cover element 2 can additionally be fastened to the holding element 1. For this purpose, the holding element 2 has a corresponding latching projection 11, which engages with the latching toothing 10 when the cover element 2, as indicated in Fig. 8 by the arrow, is pivoted upwards. The cover member 2 can then, as shown in Fig. 10 by the arrows, are moved in Fig. 10 to the left, wherein the locking projection 11 of the cover slides over the locking teeth 10 and the thickened end of the fastening tab 9 further into the mouth-like opening of the hinge member 8 is moved into it. In this way, the cover member 2 is fixed in a position concealing the holding member 1 and the lines 5A and 5B, as shown in FIG.

From Fig. 12 it is further apparent that on the cover 2 by a Randaufkantung a recess 12 is formed in the manner of a shadow gap. This recess 12 can be used for the disassembly of the cover element 2 by engaging the recess 12 manually or with a tool and, as shown in FIG. 14, the cover element 2 is displaced to the right in the figure until the Detent connection between the locking teeth 10 and the locking projection 11 dissolves and the thickened end of the fastening tab 9 has been moved to the open end of the mouth-like opening of the joint member 8. In this position, the cover 2, as indicated in Fig. 15 by the arrow, can be pivoted downwardly to allow access to the lines 5A and 5B.

In the embodiment according to FIGS. 1 and 5 to 15, the holding element 1 is additionally equipped with a holder 13, which, for example, for receiving of cables or the like can serve, which run parallel to the lines 5A and 5B and can be covered by the cover 2.

The embodiment shown in FIG. 2 differs from the embodiment according to FIGS. 1 and 5 to 15 in that the cover element 2 'is substantially rectangular, while the cover element 2 according to FIGS. 1 and 5 to 15 is rounded off is.

FIGS. 3 and 4 show a further embodiment, which is designed to receive only one line (not shown). The holding element 1 'has accordingly only a U-shaped receptacle 6. However, the assembly and disassembly of the cover 2 "takes place as described above.

In principle, the cover elements can have any shape that allows a transition between, for example, the ceiling and a wall. In particular, in terms of design, color, surface texture and / or profiling different cover elements may be provided which are suitable in the same way for mounting on the holding elements. In this case, the profiles, which are used as cover, can be produced as endless profiles or in any other suitable manufacturing process. Such covering profiles can preferably be mounted and dismounted in a particularly simple manner as described above by first connecting the covering elements to the joint members of preferably at least two retaining elements via a snap or latching connection and fastening them in the direction of a wall by lifting or pivoting and subsequent displacement become. The disassembly is then in reverse order by the cover initially pulled away from the wall and then folded down or can be rotated. LIST OF REFERENCE NUMBERS
