Description

The invention relates to a built-in part for receiving and / or mounting a poppet valve, ventilation grille or similar ventilation equipment in a recess of a wall or Deckenleichtbauplatte, wherein the mounting part an at least partially outer circumferential flange frame and an outgoing from the flange frame, in the installed state into the recess Having extending frame body, and furthermore the circumferential flange frame in the installed state in the recess area rests against the wall or Deckenleichtbauplatte, according to claim 1.

Poppet valves, which are used in conjunction with ventilation systems of buildings to metered supply air to the room or to remove exhaust air from the room, need for their attachment in drywall ceiling panels a mounting frame in the form of a built-in part. The prior art with respect to such peg valves to be mounted on the DE 81 02 933 U1 or regarding a fire damper on the DE 80 22 390 U1 made aware.

Details of a mounting flange for poppet valves shows the DE 79 01 560 U1 , There, the mounting flange consists of a metallic stamped and bent part, which can be anchored by means of special tabs in a ceiling recess. The tabs are in the teaching DE 79 01 560 U1 attached to this in the longitudinal direction of the mounting flange.

In the DE 195 25 560 C2 is assumed by a receiving frame for installing an inlet or outlet valve in a plate-shaped structure such as a wall or ceiling plate, wherein the receiving frame is formed substantially cylindrical and at the front edge has a perpendicular to the axis of the cylinder edge flange.

In the plate, an opening is present, which corresponds in size and shape of the receiving frame substantially. The receiving frame is fixed in this recess such that the edge flange comes to rest on the underside of the plate.

To fix the mounting frame on the wall or ceiling plate suggests the DE 195 25 560 C2 to form special cutting teeth on the edge flange substantially in the direction of the cylinder axis, which penetrate into the plate volume during installation of the mounting frame. Specifically, the prongs are formed from the edge flange, by each one beginning at the periphery of the edge flange, obliquely to the cylinder radius incision is introduced, the resulting tooth is to bend in a direction perpendicular to the edge flange position.

In one embodiment, the prongs are plate-shaped and provided in the direction perpendicular to the edge flange and facing away from this, provided with an arcuate taper. In an education of z. B. four prongs, which are provided at substantially equal intervals on the periphery of the edge flange, and the impressions in a ceiling or wallboard in lightweight construction there is a risk that with the penetration of the prongs in the plate material destruction occurs by the self-adjusting cutting action , In addition, there is the danger that a longer use, a loosening of the mounting frame is possible with all the resulting disadvantages.

For the above reasons, it helps at present in the assembly of built-in parts characterized by fixing on front frame holes by means of self-tapping screws fixing to the respective structural elements such. B. false ceilings or lightweight partitions. In many cases, underlay materials are still used for this purpose. In one alternative, the fixtures are wedged by driving side screws against the ceiling or partition wall material.

Fastening via front frame drillings by means of self-tapping screws on the construction elements causes problems in terms of strength and long-term stability with correspondingly porous building materials.

As is known, air intake and exhaust outlets have to be maintained and cleaned at regular intervals. These activities require partly dismantling work on the respective air intake and exhaust. In such assembly work, in particular the unscrewing a poppet valve fasteners between the mounting element and the wall or ceiling construction are exposed to high loads. This leads to less mechanically resistant in particular porous building materials to their damage and thus the failure of the compound. Incidentally, the known components require a very high installation costs.

In the generic AT 500 632 B1 the flanged ring has a plurality of fastening tabs which project outward from the connecting piece and which are anchored with screws.

From the foregoing, it is therefore an object of the invention, an advanced built-in part for receiving and / or attachment of a poppet valve, ventilation grille or similar ventilation Specify equipment that allows a tool-free pre-assembly on the corresponding wall or ceiling lightweight panel element and this can be done in a short time.

The object of the invention is achieved by a built-in part according to the combination of features according to claim 1 and the specific embodiments according to claim 2 and 5, wherein the further subclaims include at least expedient refinements and developments.

It is therefore assumed that a built-in part for receiving and / or mounting a poppet valve, ventilation grille or similar ventilation equipment, wherein the mounting part is to be introduced in a recess of a wall or ceiling lightweight board. The built-in part has an at least partially outer circumferential flange frame and an outgoing from the flange frame, in the installed state in the recess extending into the frame body. Furthermore, the circumferential flange frame is in the installed state in the recess area on the wall or ceiling lightweight board, in particular on the underside.

According to the invention circumferentially spaced incisions or stampings are provided in the frame body, which bent after penetration of the frame body in the respective recess in Flanschrahmenrichtung tongue-like outward fix the fixture in the wall or Deckenleichtbauplatte.

In a first embodiment of the invention, the recesses or stampings for bending out tongues can be formed such that the respective bending line runs essentially parallel to the plane of the flange frame.

The bending line has a distance from the flange frame plane equal to or greater than the thickness of the wall or ceiling board.

To further improve the hold of the fixture in the respective wall or Deckenleichtbauplatte in this embodiment of the invention, the possibility in the tongues an opening, in particular formed as a slot to form the thread of a fastening screw.

In this case, tongue-related complementary openings are present in the flange frame.

In a second embodiment of the invention, the cuts or stampings for bending out of tongues are formed so that the respective bending line extends substantially perpendicular to the plane of the flange frame.

In this case, the respective flange frame-next incision may have a skew to form a conical tongue portion. In this way, tolerances in the thickness of the wall or ceiling lightweight board can be compensated in the region of the recess and a secure fixing of the insert can be effected.

In this embodiment of the invention, the respective tongue may be formed as a triangular surface, a trapezoidal surface or a rectangular surface with a one-sided conical shape.

For both embodiments of the invention is that the respective tongue in the outwardly bent state has a longitudinal extent which is equal to or greater than the width of the respective flange frame. This also contributes to a significant improvement in the attachment of the fixture in the recess in the respective wall or ceiling plate.

The remaining after the bending out of the tongues openings can be closed to prevent erroneous air flows.

In this case, such a closure can be formed by a rubber-like strip which is attached to the installation part on the production side. About an actuating slot in the rubber-like strip in the region of the respective tongue herauszuschiegenden a tool, for. B. a screwdriver are introduced to perform the bending movement. With the removal of the screwdriver, the corresponding gap closes by the rubber-elastic properties of the closure material.

Alternatively, however, a subsequent bonding with an adhesive tape, which is resistant to cleaning and abrasion, be made.

Due to the above-mentioned tongues, which act as a sort of setting-up or deployment angle, results in a very fast and non-positive mounting of the corresponding mounting parts. On the respective frame body hoses can be easily mounted in a professional manner. Leakage rates at the connections are reduced to a minimum, as well as an unintentional loosening of corresponding connection hoses when z. B. a poppet valve on classic threaded or bayonet locks must be removed from the mounting part to allow for cleaning.

Another advantage of the solution according to the invention is that an accurate alignment of the mounting parts can be done on the respective wall and ceiling materials.

For the following explanation of the invention with reference to the embodiments, the same reference numerals are used for the same means.

In the first embodiment of the invention according to the explanations with reference to FIG 1a to 1d such as 2a to 2d is assumed by incisions or stampings in the fitting for bending out tongues such that the respective bending line is oriented substantially parallel to the plane of the respective flange frame.

In the respective wall or ceiling light component 1 there is a recess (see 1a and 2a ), on the respective dimensions of the insert, in particular the frame body 2 , is turned off.

In the built-in part with a cylindrical frame body 2 according to the 1a to 1d U-shaped punches are introduced to a Nachaußenbiegen to obtain a tongue 3 to enable.

After the tongue 3 has been bent out, leaving an opening 4 in the frame body.

On the mounting side, first the frame body without bent out tongues 3 introduced into the recess in the wall or Deckenleichtbauplattenteil and it can be attached to a not shown in the figures ventilation hose.

After that, by means of a simple tool, a bending out of the respective tongues 3 in the direction of the surrounding wall or Deckenleichtbauplatte done.

If, as in the 1a to 1d shown the respective tongues 3 another opening, z. B. formed as a slot 6 own, can a fixing screw 5 from the bottom of the wall or ceiling lightweight board 1 be screwed. For this purpose are in the outer circumferential flange frame 7 positionally complementary bores or openings 8th available.

The formation of the openings as a slot 6 in the respective tongue 3 leads to a further assembly facilitation.

Like from the 1a to 1d can be seen, the cuts or stampings for bending out the tongues 3 designed so that the respective bending line 9 substantially parallel to the plane of the flange frame 7 is located or runs accordingly.

The bend line 9 here has a distance from the flange frame plane, in a measure equal to or greater than the thickness of the wall or ceiling panel 1 , This ensures that the simple bending out of the respective tongues 3 already a montageerleichternde Fixage of the insert is given.

The education of the tongues 3 according to the representations after the 2a to 2d take place in an analogous manner as to the 1a to 1d explained.

With reference to the embodiment according to the 2a to 2d It will be apparent that the fitting completely different geometric shapes, eg. B. may have formed as a grid with rectangular cross-section, without leaving the principle of the invention attachment.

The installation of the insert according to the representations of the 1a to 1d and 2a to 2d takes place as explained below.

First, the built-in part is introduced after connection to the air duct system in the wall or ceiling construction. For this purpose, the mentioned recess is required as a corresponding opening in the wall or ceiling lightweight panel part.

After inserting the fixture in the wall or ceiling construction, the tongues are pressed outwards in the direction of the flange frame, which can be done manually. This results in a loose attachment, for further assembly, d. H. the insertion of the screws is sufficient.

The respective screwed screws capture the tongues through the slot or slot and pull the corresponding tongue over the entire surface on the back or top of the wall or ceiling construction. Thus, the respective structural element is non-positively encompassed with the result of a secure and long-term stable attachment of the insert.

After the work has been completed, the openings formed by bending out the tongues are sealed airtight by a stopper or by means of adhesive tape or suitable adhesive materials.

In an alternative embodiment, on the inside in the region of the frame body, at least where the bending out of the tongues is to take place, a rubber-elastic closure in the form of a thin rubber strip is provided, which has a slot. By inserting a tool can then be made the bending out of the tongues. The rubber-elastic properties cause in this case that sets an independent closing after pulling out the tool.

According to the second embodiment of the 3a to 3d and 4a to 4d is in turn of a built-in part as poppet valve mounting ring ( 3a to 3d ) or as a grommet ( 4a to 4d ) went out.

In contrast to the first embodiment of the invention, however, here the notches or punches for bending out the tongues are designed such that the resulting respective bending line is substantially perpendicular to the plane of the flange frame 7 extends.

The bending line is here also with the reference numeral 9 Mistake.

In the example shown, the tongues are 3 circumferentially equally spaced formed. For a corresponding attachment of the insert with frame body 2 and flange frame 7 suffice three out-turned tongues 3 ,

In the second embodiment of the invention is the respective flange frame 7 next cut in the material of the frame body 2 with a skew to form a conical tongue portion 10 executed. Due to the taper, tolerances in the thickness in the region of the section of the wall or ceiling lightweight board 1 balanced and a further improvement in fixing the respective fixture be effected.

In principle, there is the possibility that the respective tongues in the bent-out state have a triangular surface, a trapezoidal surface or a rectangular surface with a one-sided conical profile.

As in particular from the 3b and 3c or 4b and 4c can be seen, the respective tongue 3 in the outwardly bent state, a longitudinal extent equal to or greater than the width of the respective flange frame 7 is.

In the formation of a ventilation passage in the form of a box-shaped housing with a side annular nozzle 11 is again assumed by a fastening method and a solution according to the first embodiment of the invention, wherein the cuts or stampings for bending out the tongues 3 are formed so that the respective bending line 5 substantially parallel to the plane of the flange frame 7 runs.

In the second embodiment of the invention, with recesses or punches for bending out tongues, which are designed such that the respective bending line extends substantially perpendicular to the plane of the flange frame, the preparation of the assembly, as explained for the first embodiment of the invention, takes place. After inserting the fixture in the corresponding recess in the wall or ceiling construction, the tongues are pressed outwards, which can be done without tools or with the help of a screwdriver. The top of the wall or Deckenleichtbauplatte in the region of the recess is covered by the lower edge of the tongue, so that the fixture is fixed. The formation of the conical tongue section 10 with additional cutting edge effect improves the hold of the insert.

In one embodiment of this embodiment of the invention, it is possible to make the bending out of the tongues alternately in the rotational and counter-rotation direction of a later to be screwed poppet valve. This ensures a secure hold of the insert both when screwing the poppet valve in the frame body as well as the removal of the same for cleaning purposes.
