Fittings for receiving and / or fixing a poppet valve, ventilation grille or similar ventilation equipment

description

The invention relates to a built-in part for receiving and / or fixing a poppet valve, ventilation grille or similar ventilation equipment in a recess of a wall or ceiling lightweight board, wherein the

Built-in an at least partially outer circumferential flange and a flange frame outgoing, in the installed state in the

Having recess in extending frame body, and continue the circumferential flange frame in the installed state in the recess area on the wall or ceiling lightweight board rests, according to the preamble of 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 fastened attention is drawn to the DE 81 02933 Ul or with respect to a fire damper on the DE 8022390 Ul.

Details of a mounting flange for poppet valves is shown in DE 7901 560. There, the mounting flange of a metal stamped and bent part, which can be anchored with the help of special tabs in a ceiling recess. The tabs are in the teaching of DE 7901 560 in the longitudinal direction of

Mounting flange attached to this.

In the generic DE 19525560 C2 is of a receiving frame for installation of an inlet or outlet valve in a plate-shaped

Structure assumed as a wall or ceiling plate, the

Receiving frame is formed substantially cylindrical and on the

Front edge has a perpendicular to the axis of the cylinder oriented edge flange.

In the plate there is an opening that in size and shape the

Recording frame. The recording frame will be in this recess fixed in such a way that the edge flange comes to rest on the underside of the plate.

For fixing the mounting frame to the wall or ceiling plate, DE 19525560 C2 proposes to form special cutting teeth on the edge flange essentially in the direction of the cylinder axis, which in the installation of the

Receiving frame into the plate volume. Specifically, the prongs are formed from the edge flange, by one at the periphery of the

Randflansches incipient, obliquely to the cylinder radius oblique incision is introduced, the resulting spike in a for

Edge flange is to bend vertical 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 embodiment of e.g. four prongs, which are at substantially equal intervals on the circumference of the

Randflansches are provided, and the impressions in a ceiling or wall panel in lightweight construction there is a risk that with the

Penetration of the teeth in the plate material destruction occurs by the self-adjusting cutting action occurs. 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 is currently made in the assembly of built-in parts by fixing on front frame holes by means of self-tapping screws fixing to the respective structural elements such. False ceilings or lightweight partitions done. In many cases, underlay materials are still used for this purpose. In an alternative, the fixtures are wedged by driving side screws against the ceiling or partition wall material.

The attachment via front frame holes 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, the fasteners between the mounting element and the wall or

Ceiling construction exposed to high loads. This leads to less mechanically resistant in particular porous building materials to their

Damage and thus failure of the connection. Incidentally, the known components require a very high installation costs.

From the foregoing, it is therefore an object of the invention to provide an advanced built-in fixture for receiving and / or mounting a poppet valve, ventilation grille or similar ventilation equipment that allows safe long-term stable connection to the corresponding wall or ceiling lightweight panel element and the installation almost without tools in a short time can be done.

The object of the invention is achieved by a built-in part according to the feature combination according to claim 1 and the specific embodiments according to claim 2 and 6, wherein the beyond

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 one of

Flange frame outgoing, in the installed state in the recess extending into the frame body. Furthermore, the circumferential lies

Flange frame in the installed state in the recess on the wall or Deckenleichtbauplatte, especially at the bottom of.

According to the invention are peripherally spaced in the frame body

Incisions or punches provided, which after the penetration of the frame body in the respective recess in Flanschrahmenrichtung

tongue-like bent outward the built-in part in the wall or

Fix ceiling light board.

In a first embodiment of the invention, the recesses or punches for bending out tongues can be formed so that the respective bending line is substantially 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 ceiling lightweight board 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 insert in the

Recess in the respective wall or ceiling plate at.

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. Via an actuating slot in the rubber-like strip in the region of

respective tongue to be extracted can be a tool, e.g. a screwdriver are introduced to perform the bending movement. With the

Pulling out the screwdriver closes the corresponding gap 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

inadvertent release of corresponding connection hoses when e.g. a poppet valve on classic threaded or bayonet from the

Built-in must be removed 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.

The invention will be explained below with reference to exemplary embodiments and with the aid of figures.

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 FIGS. La to ld and 2a to 2d is of incisions or

Stampings in the insert for bending out tongues assumed 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 is a

Recess (see Fig. La and 2a), which is on the respective dimensions of the insert, here in particular the frame body 2, turned off. In the internals with a cylindrical frame body 2 as shown in FIGS. La to ld U-shaped stampings are introduced to allow Nachaußenbiegen to obtain a tongue 3.

After the tongue 3 has been bent out, an opening 4 remains in the

Frame body.

On the mounting side, the frame body is initially introduced without bent tongues 3 into the recess in the wall or ceiling lightweight panel part and it can be plugged into the figures not shown ventilation hose.

After that can be done by means of a simple tool bending out of the respective tongues 3 in the direction of the surrounding wall or ceiling lightweight board.

If, as shown in Figures la to ld, the respective tongues 3 still have an opening, e.g. formed as a slot 6, a fastening screw 5 can be screwed from the bottom of the wall or ceiling lightweight board 1. For this purpose, positionally complementary bores or openings 8 are present in the outer peripheral flange frame 7.

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

As can be seen from FIGS. 1 a to 1 d, the cuts or punches for bending out the tongues 3 are designed in such a way that the respective

Bending line 9 is substantially parallel to the plane of the flange frame 7 or runs accordingly.

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

The formation of the tongues 3 according to the illustrations according to FIGS. 2 a to 2 d take place in a manner analogous to that of FIGS. 1 a to 1 d. With reference to the embodiment according to FIGS. 2a to 2d, it can be seen that the installation part has completely different geometric shapes, eg

may have formed as a grid with rectangular cross-section, without departing from the principle of the invention fastening.

The assembly of the insert according to the representations according to FIGS. 1a to 1d and 2a to 2d is carried out 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 is the mentioned

Recess required as a corresponding opening in the wall or Deckenleichtbauplatten- 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, which is suitable for further assembly, i. 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 passed through a stopper or adhesive tape or

suitable adhesive materials hermetically sealed.

In an alternative embodiment, the inside is in the range of

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 attached, 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 according to FIGS. 3 a to 3 d and 4 a to 4 d, a built-in part is again assumed to be a poppet valve mounting ring (FIGS. 3 a to 3 d) or as a grid connection (FIGS. 4 a to 4 d).

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

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

In the example shown, the tongues 3 are circumferentially equally spaced. For a corresponding attachment of the insert with

Frame body 2 and flange frame 7 satisfy three outwardly bent tongues. 3

In the second embodiment of the invention is the respective

Flange frame 7 next incision in the material of the frame body 2 with a skew to form a conical tongue portion 10th

executed. Due to the conicity tolerances in the thickness in the region of the section of the wall or ceiling lightweight board 1 can be compensated and a further improvement in fixing the respective fixture can be effected.

Basically 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 unilateral conical shape.

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

In the formation of a ventilation passage in the form of a box-shaped housing with 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 the tongues 3 are formed so that the respective bending line 5 is substantially parallel to the plane of the flange frame 7. In the second embodiment of the invention with incisions or

Tongues for bending out tongues, which are executed so that the respective bending line is substantially perpendicular to the plane of the

Flange frame extends takes place, the preparation of the assembly, as explained for the first embodiment of the invention. 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 mounting part is fixed. The formation of the conical tongue portion 10 with additional cutting edge effect improves the hold of the insert.

In one embodiment of this embodiment of the invention, it is possible, the bending out of the tongues alternately in rotary and

Counter-rotation of a later to be screwed poppet valve make. 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.
