Abstract

During the renovation of part of a building, those rooms nor affected are sealed off by a dust seal panel placed over a link-door. The temporary hinged panel (20) is placed in front of the existing door and attached to the door frame (R).

Description

The invention relates to a mobile dust protection device according to claim 1.

For renovation or renovation work, but also for alterations, carpentry, grinding and the like. regularly accumulate large amounts of dust and dirt. This is distributed evenly in the room; even through closed doors.

Therefore, if an apartment or a building area partially renovated or -renoviert, for example, in the bathroom or toilet area, not affected by the work, mostly used or inhabited spaces are also heavily burdened. Repeated cleaning is the result, which is not only time consuming, but also causes high costs. The health and nervous stress is very high.

Dust-tight masking of the doors usually does not help much because the space in which the work is to be carried out is no longer accessible. The use of pre-hung foils is also ineffective, because it either narrows the passage too much or makes it permanently open again because craftsmen have to enter or leave the room with bulky tools or materials.

To counter this, dust protection devices have been developed, which are installed in the door or window frames instead of the existing doors or windows. DE-U1-200 21 929 discloses a flexible closure element made of dust-tight textile fabric for door or window openings, the edges in a door or Window reveal or in a door or window frame are fastened and can be separated by means of a zipper.

Although such a closure element clamped in the door frame and fixed with adhesive strips seals the door passage almost completely. The disadvantage, however, is that to open the passage is only partially released, which is often a hindrance to the transport of bulky material or larger tools. If you hang on the textile fabric, this can easily tear out of the door frame on which - even after regular disassembly - often remain adhesive residues that are consuming to remove. Another problem is that dust and dirt particles get stuck in the zipper. The opening and closing of the closure element is thereby hindered, so that the door is left open at the end again and again.

The aim of the invention is to overcome these and other disadvantages of the prior art and to develop a mobile dust protection device that prevents the discharge of dust and dirt from rooms as far as possible and easy to open and close in construction site operation. At the same time, almost the entire opening cross-section of a door or window should be available as a passageway. The aim is also a cost-effective design that is easy to assemble and disassemble and easy to transport.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 17.

The object is achieved in that a dust protection device for passages or openings in walls, in particular for doors, a surface element which is pivotally mounted in front of a door frame and rests in the closed position sealingly on the door frame.

In this way, the discharge of dust and dirt from the space to be closed is largely prevented, because the surface element always closes the passage sealingly. The opening of the device is particularly simple because the surface element is pivotally mounted. You only have to swing it up and you can use the entire passage almost completely. The annoying opening and closing of zippers is therefore not necessary. On the contrary: the surface element can be opened in doubt even without hands. Another Advantage is that the dust protection device can be attached in front of the door frame. It can therefore be installed at any time without much effort.

Suitably, the surface element is a door leaf and larger than the breakthrough to be closed, in particular larger than the door frame. This reliably prevents dust and dirt from being able to escape. Furthermore, you can use the dust protection device almost universally for breakthroughs of different sizes.

Another aspect of the invention provides that the surface element is pivotally mounted in hinges, each hinge having a sleeve into which the surface element is suspended. The dust protection device can thus be quickly set up and removed at any time. The handling is extremely simple.

Advantageously, the hinges before and / or next to the door frame attachable. In particular, each hinge is arranged on a bracket which can be fixed on or in the door frame. Such a construction can be realized inexpensively by simple means.

Another important embodiment provides that the hinges and / or the brackets by means of a support in front of and / or adjacent to the door frame are attachable, the hinges and / or the brackets are fastened to the support. This allows a mounting of the dust protection device without that the breakthrough or the door frame are damaged. After dismantling the device only the previous door must be hung again. The assembly effort is therefore extremely low.

This also contributes, if the support is non-positively and positively fixed between the door frame and the floor, especially if the support is a telescopic support. As a result, not only the door frame during installation of the dust protection device is not damaged. The assembly can be carried out in no time without any tools, which has a favorable overall effect on the cost.

Structurally, it is advantageous if at least one compression spring is provided within the support.

The invention further provides that the surface element is acted upon by a permanent closing force. This ensures that the dust protection device is constantly closed. The closing force is preferably generated by a tension spring, which pulls the surface element against the door frame.

In order to further increase the sealing effect of the dust protection device according to the invention, a circumferential seal is provided between the surface element and the door frame.

For transport and storage, it is advantageous if the surface element is foldable or can be disassembled into at least two partial surfaces.

Further advantages are obtained if the hinges can be attached in front of and / or next to the door frame, in particular if each hinge is arranged on a bracket which can be fixed to or in the door frame. The entire device is thus easy to handle.

An important embodiment of the invention provides that the hinges and / or the brackets by means of a support in front of and / or adjacent to the door frame are attachable. For this purpose, the hinges and / or the brackets are preferably attachable to the support, the latter being non-positively and positively lockable between the door frame and the floor. This not only achieves an extremely cost-effective design that can be quickly assembled and disassembled. The dust protection device can also be easily handled and transported. In particular, the dust protection device can be mounted quickly even by inexperienced craftsmen.

A development of the invention provides that the surface element is acted upon by a permanent closing force. This has the advantage that the surface element is immediately returned to its closed position after each pivoting. The breakthrough can never be open.

The dust protection device generally designated 10 in FIG. 1 is designed as a dust protection door, which in its closed position closes a passage D in a wall W in a dust-tight manner. The passage D is for example a door T with a door frame R and a (not shown) door leaf.

The dust protection door 10 has a rigid surface element 20 in the form of a door leaf 20, which is pivotally mounted in front of the door frame R. For this purpose, two hinges 30 are arranged laterally next to the door leaf 20, which are each attached to a console 40. The latter are supported by a tubular support 50 which is positively and positively fixed between the door frame R and the floor B.

As shown in FIG. 2, the bracket 40 is formed by an angle 42 which rests flat with two legs 43, 44 on the front and side surfaces of the door frame R. Between this and the angle 42 are pad 45 made of plastic, foam or the like. arranged so that the door frame R is not damaged. The support pads 45 are preferably glued to the angle 42.

The resting on the wall side (front) surface of the door frame R leg 43 of the angle 42 carries the end of the hinge 30, which is essentially formed by a sleeve 32. This has centrally a through hole 33 for receiving an L-shaped bolt 24. This has a first leg 25 which is anchored in the side edge 22 of the door leaf 20. A second leg 26 extends parallel to the side edge 22. It is - as shown in Fig. 3 - inserted as a journal from above rotatably in the bore 33 of the sleeve 32. The bolt 24 and the sleeve 32 form the hinge 30, wherein the door leaf 20 with the axle journal 26 can be switched on and off at any time.

In order to obtain a height adjustment for the door leaf 20, one can either from below into the through hole 33 of the sleeve 32 a (not shown) screw support screw, so that the axle journal 26 is supported on the support screw. Or you bring on the with an (unspecified) external thread provided axle journal 26, a nut 28 which is supported from above on the sleeve 32 (see Fig. 3).

At the resting on the side surface of the door frame R leg 44 of the angle 42, a tube sleeve 46 is fixed, whose inner diameter is slightly larger than the outer diameter of the tubular support 50. The console 40 is pushed with the tube sleeve 46 on the support 50 and by means of a locking bolt 48 fixed at a predetermined height above the ground B. For receiving the locking bolt 48 50 holes 58 are introduced both in the tube sleeve 46 and in the support.

The support 50 can - as indicated in Fig. 1 - sections be provided with a plurality of holes 58 which lie vertically at equal intervals. In this way, one can set the console 40 - depending on the structural conditions on site - quickly and easily at different heights. However, it is also possible to provide only the tubular sleeve 46 with a bore 58 and execute it as a threaded bore. The locking pin 48 is then a clamping screw which is screwed into the threaded bore 58, so that the support 50 is clamped in the tube sleeve 46. A nut (not shown) welded over the bore 48 on the tube sleeve 46 stabilizes the guidance of the clamping screw 48, so that the bracket 40 can always be fixedly mounted on the support 50.

The angle 42, the sleeve 32 and the tube sleeve 46 are preferably made of metal and firmly welded together. But you can also form the parts 32, 42, 46 in one piece and made of metal, plastic or a composite material. The door leaf 20 is preferably made of a lightweight, transparent plastic material.

The support 50 is preferably a telescopic support with a lower tube portion 52 and an axially displaceably guided therein upper tube portion 53. The lower end of the lower tube portion 52 forms a rubber buffer 54, with which the support 50 is non-slip on the bottom B is supported. The upper end of the lower tube part 52 is open to receive the upper tube part 53. The upper end of the upper tube part 53 forms a rubber buffer 55, which comes to rest on the underside of the door frame R. The lower end of the upper tube part 53 is fired by a cap 56.

Within the lower tube portion 52, a spring 57 is arranged, which is supported on the lower rubber buffer 54 and the cap 56 of the upper tube portion 53, so that both tube portions 52, 53 are pressed apart when inserted into the door frame by the spring 57. The support is therefore frictionally clamped between the door frame R and the bottom B. A funnel-shaped plastic cap 59 encloses both the displaceably mounted tube part 53 and the upper end of the lower tube part 52, so that it is always sealed.

Between the door leaf 20 and the door frame R, a circumferential seal 60 is arranged, which is fixed, for example, on the door leaf 20. For this purpose it is expedient to use a double-sided adhesive tape (not shown) or the seal 60 is self-adhesive. The latter preferably consists of a relatively soft, elastically deformable material, which clings dust-tight to the door frame R.

Another embodiment of the dust door 10 according to the invention provides that the seal 70 is not applied to the door 20, but on the door frame R. This is always advantageous if the door frame R has projecting trim or edge strips. The seal 70 is glued circumferentially in this case on the highest elevation. In addition, the hinges 30 are - as indicated in Fig. 1 - outside the trim or edge strips so that the door 20 can be completely sealed on the highest elevation of the door frame R rest. Thus, the hinges 30 are laterally adjacent to the door frame R, the front leg 43 of the angle 42 is formed correspondingly long.

The cross section of the seal 60 may be rectangular. But man can also form the seal 60 prism-shaped or with a semi-circular cross-section. It is important that the sealing profile always dust-tight on the door frame R and in the region of the hinges 30 resting on the door frame R leg 43 of the angle 42 adapts.

So that the door 10 always reliably seals the space to be closed in its closed position, a tension spring 70 is arranged between the door leaf 20 and the support 50, permanently pulling the door leaf 20 and the seal 60 against the door frame R. In this way, the door 10 is not only permanently closed tight. It is, when it has been opened, immediately closed again, so that the discharge of dust and dirt from the room is largely prevented.

To fix the spring 70, a ring 72 is provided on the support 50, in which one end of the spring 70 can be suspended. The other end of the spring 70 is connected to the door leaf 20, for example with a hook 74th

It can be seen in Fig. 1, that the surface of the door leaf 20 is always so large that the door frame R is generously covered. The dust cover door 10 therefore fits almost all common door frames R and can be used universally.

To facilitate transport, you can form the door 20 20 two or more parts. The individual (not shown) wing parts can be hinged together, especially by large-scale (also not shown) film or film hinges, so that you can fold the door 10, the entire door surface, however, is always dustproof. The fixation of the wing parts is done by laterally attachable bars or U-profiles. Further, one can provide a hinge 30 in the region of each kink, so that the door 20 when hanging in the hinges 30 stabilizes itself.

The assembly of the dust door 10 according to the invention is extremely simple:

First, the telescopic support 50 is mounted by the upper tube part 53 is inserted into the lower tube part 52. Subsequently, a bracket 40 is placed on each tube part 52, 53, wherein the tube sleeves 46 are fixed with the locking pin 48 in the holes 58.

You so prepared support 50 - which may also be factory pre-assembled depending on the application - is now inserted laterally into the door frame R, wherein the lower tube part 52 on the floor and the upper tube part 53 are supported at the upper end of the door frame R. The integrated in the Stützte spring 57 presses the tube parts 52, 53 permanently apart, so that the support is positively and positively fixed. The end formed rubber buffers 54, 55 provide a firm grip, even on smooth surfaces.

When inserting the support 50 in the door frame R is merely to ensure that the angle 42 of the brackets 40 with the legs 43, 44 rest flat on the front and side surfaces of the door frame R.

Subsequently, the door 20 is mounted with its axle 26 in the sleeves 32 of the hinges 30 and provided with the seal 60, if this - for example, in standard door frame R - is not also already factory pre-assembled.
