Description

The present invention relates to a dust protection door for temporary insertion into a door frame or a wall opening of a building, which dust protection door comprises a door frame and a door leaf pivotably mounted on the door frame about a pivot axis.

Dust protection doors of the type described above are used in particular during renovation work, to prevent emerging dust from the room in which worked, can escape. In particular, the dust-proof door allows people to enter the room easily and quickly and to seal it again by closing the dust-proof door.

A dust protection door of the type described above is for example from the DE 20 2014 001 202 U1 known. As explained in this utility model, such dust protection doors may have dimensions of the order of 1.9 m in height and 0.7 m in width. Since they are only used temporarily, they have to be transported to a construction site and also transported away again. Dust protection doors of the specified size are therefore extremely cumbersome to handle.

It is therefore an object of the present invention to improve a dust door of the type described above in their handling.

This object is achieved with a dust door of the type described above according to the invention that the door leaf and the door frame are each formed in several parts and that the door leaf comprises a plurality of door leaf parts, that the door frame comprises a plurality of coupled together in a working position door frame parts and that the plurality of door frame parts in one Transport position completely separated or pivoted by a folding angle against each other.

The inventively proposed further development of a dust door of the type described above has the particular advantage that the dust cover door can be transferred to a total of compact size for a transport. The door leaf may in particular comprise a plurality of door leaf parts, which are optionally pivoted against each other and so can be folded. Alternatively, they can be completely separated from each other to disassemble the door leaf into several door leaf parts for transport. Likewise, the door frame, which includes a plurality of coupled door frame parts in the working position, are completely disassembled into the individual door frame parts, so that they are separated from each other. Alternatively, the door frame parts can also be pivotally coupled to each other to fold them from the working position to the transport position by being pivoted about a folding angle against each other. Optionally, the plurality of door leaf parts can also be separated from the several door frame parts, so that the dust protection door can be formed essentially completely dismantled. Such a further developed dust protection door can therefore be reduced, for example, to half their height in the working position for transport. If more than two door leaf and door frame parts are provided, the height of the dust protection door, which has these in the working position, can be further reduced for transport. For example, two, three, four or even more door leaf and door frame parts can be provided.

The dust protection door can be designed to be particularly easy to handle if the door leaf is formed in two parts and comprises an upper door leaf part and a lower door leaf part if the door frame is in two parts and comprises an upper door frame part and a lower door frame part, when the upper door leaf part is pivotably mounted on the upper door frame part is and when the lower door leaf part is pivotally mounted on the lower door frame part. Above and below in this context refers to the direction of gravity. Such a two-part design of the door leaf and door frame of the dust door makes it possible, in particular, to quickly halve by simply disassembling the door frame and the door leaf, for example by completely separating the parts from each other or folding them together, a height of the dust door, which occupies it in the working position , To transfer the dust door from the transport position to the working position, only the two door frame parts must be coupled together or folded or pivoted from the transport position to the working position and the two door leaf parts are also pivoted against each other or connected.

If the door frame is designed in particular not hinged, it is advantageous if the dust protection door comprises a coupling device for coupling the plurality of door frame parts, which are separated from each other in the transport position, in the working position. The coupling device thus serves in particular to couple or connect the several door frame parts in the working position.

The coupling device can be formed in a simple manner if it is designed in the form of a plug connection device.

It is favorable if the coupling device has at least one first coupling element and comprises at least one second coupling element, which are arranged on one side of one of the plurality of door frame parts and on the other on another of the plurality of door frame parts and which are non-positively and / or positively engaged in the working position and which are disengaged in the transport position. With such a coupling device, the plurality of door frame parts can be easily coupled with each other, when the first and second coupling elements, which are disengaged in the transport position, are brought into engagement. This can be done in particular non-positive and / or positive.

The coupling device can be formed in a simple manner when the at least one first coupling element is in the form of a coupling projection and when the at least one second coupling element is designed in the form of a coupling receptacle for frictionally and / or positively locking the at least one coupling projection. For example, one or two coupling projections or one or two coupling receptacles may be formed on a frame part in order to couple the one frame part to the other frame part. It is also conceivable to provide a coupling projection and a coupling receptacle on a door frame part. In particular, only coupling receptacles may be provided on the plurality of door frame parts, which are coupled to one another via a coupling member which simultaneously serves as a coupling projection for both door frame parts.

It is favorable if the door frame is formed from a plurality of frame sections and if the at least one coupling receptacle defines a longitudinal axis which runs parallel to one of the several frame sections of the door frame on which it is arranged or formed. In this way, the door frame can be assembled simply by plugging together.

The dust protection door can be designed to be particularly simple and compact if the at least one coupling receptacle is formed by a cavity defined on one of the several frame sections. For example, the one of the several frame sections or also all the frame sections may be formed from a hollow profile, so that then each frame section comprises an elongated cavity.

The door frame can be simply and safely coupled in the working position if the at least one coupling projection is designed in the form of a coupling pin corresponding to the cavity. In particular, a cross-section of the coupling pin can be adapted to a cross-section of the cavity so that it can be inserted in a positive-locking and / or non-positive manner into it.

According to a further preferred embodiment of the invention can be provided that the coupling pin engages in each case partially in each case a cavity of two of the plurality of frame sections and in particular on one of these two frame sections, which it connects in the working position, is attached. The coupling pin can thus optionally be completely separated from the plurality of frame sections and connect two frame sections in the working position with each other. Optionally, it can be attached to a frame section so that it can not be lost when transporting the dust protection door.

The handling of the dust door is particularly simple when the coupling pin is fixed to the frame section force, shape and / or cohesively. In particular, it may be fixed to a frame section by gluing, clamping and / or screwing. A projecting from this frame portion of the coupling pin can then engage in a coupling receptacle of the other frame portion in the working position.

It is advantageous if each of the plurality of door frame parts comprises two legs running parallel to one another and if one of the several door leaf parts is pivotably mounted on one of these two legs. This makes it easy to form a door frame for the dust door.

Conveniently, the upper door frame part is substantially U-shaped and comprises a lintel interconnecting the two legs. In this way, the two legs can be kept at a desired distance from each other. The lintel then defines the width of the dust protection door.

A particularly stable in the working position dust protection door can be formed in particular by the fact that the lower door frame part is substantially U-shaped and comprises a crosspiece connecting the two legs together. Thus, similar to the lintel on the upper door frame part of the cross bar connect the legs of the lower door frame part with each other. If both a door lintel and a cross bar are provided on the door frame, a circumferential door frame can be formed.

The dust protection door can be designed to be particularly lightweight and stable when the door frame is formed from a hollow profile. In addition, it allows the formation of the door frame of a hollow profile, that in the door frame parts by the Hollow profile defined cavities can be used as coupling receptacles for the coupling device.

The dust protection door can be designed simply and inexpensively if the hollow profile has a polygonal cross section. In particular, the cross section may be rectangular or square. Optionally, a multi-chamber hollow profile can be used to form the door frame.

It is advantageous if the door frame defines a door opening which is closed in a closed position by the door leaf, and if a door leaf stop is formed protruding on the door frame, which reduces a free cross section of the door opening. Such a door leaf stop can thus pretend a defined closure of the dust protection door. Optionally, closure elements can be provided which hold the door leaf in the closed position. In particular, magnetic closure elements can be provided here which are optionally arranged or formed on the door frame and / or on the door leaf and hold the dust protection door in the closed position. Optionally, of course, can be dispensed with the door leaf stop, so that the dust protection door can be designed in the form of a swing door.

In order to be able to achieve in particular optimal dustproofness, it is advantageous if the door leaf stopper is formed circumferentially on the door frame.

Conveniently, the dust protection door comprises a securing device for securing the coupling device in the working position. The safety device thus serves in particular to secure the dust protection door in the working position in which the plurality of door frame parts are coupled together by the coupling device against accidental disconnection or disassembly.

It is advantageous if the securing device comprises at least one first and at least one second securing element, which are arranged or formed on one side of the plurality of door frame parts and on another of the plurality of door frame parts and which engage positively and / or positively in a locking position and which are disengaged in a Entsicherungsstellung. The fuse elements are therefore not formed in particular identical to the coupling elements. They serve rather to secure the coupling device in the working position. This is the case when the cooperating securing elements occupy the securing position. To disassemble the dust door, the mutually engaged locking elements must first be disengaged so that they take the armed position. Only then can the several door frame parts be transferred from the working position into the transport position.

The dust protection door can be embodied particularly simply if the securing device comprises at least one tension lock with a first securing element in the form of a retaining projection and a second securing element in the form of a tensioning bow, which at least partially engages behind or engages in the retaining projection in the working position. In particular, a plurality of tension locks may be provided. For example, a clamping closure can be provided for each coupling point of the coupling device on which a first and a second coupling element engage in the working position.

Further, it is advantageous if the at least one first securing element in the form of a securing projection and if the at least one second securing element in the form of a securing receptacle for non-positive and / or positive receiving the at least one securing projection is formed. In particular, a longitudinal axis of the securing receptacle can run transversely to a longitudinal axis of the coupling receptacle. In particular, transverse here does not mean parallel. Cross may mean in particular perpendicular.

In a simple way, the securing device, if the at least one fuse holder is formed in the form of an opening which passes through a frame portion and engaging in this in the working position coupling projection transversely to its longitudinal axis and if the securing projection in the form of a in the working position in the Opening engaging safety pin is formed. The aperture may be formed for ease of manufacture, in particular in the form of a bore. Its longitudinal axis can in particular pass through the coupling projection perpendicular to its longitudinal axis. It is advantageous if the at least one door leaf part comprises a rectangular door leaf frame part. In this way, the at least one door leaf part can be particularly light and stable at the same time. Furthermore, the opening defined by the rectangular door leaf subframe can be closed in any manner, for example by a plate or a foil.

Preferably, the door leaf part frame defines an opening which is closed by a flat closure element. In this way, dust is prevented from escaping through the opening defined by the door leaf subframe.

The dust protection door can be designed simply and cost-effectively if the closure element is designed in the form of a plate or a foil. In particular, the closure element may be provided with an opening through which, for example, a Zuluft- or exhaust air hose of an air filter device can be performed dustproof.

Preferably, the closure element is transparent or translucent. This allows in particular that you can see through the dust door.

Furthermore, it may be advantageous if the dust protection door comprises a connecting device for connecting the plurality of door leaf parts in the working position. Thus, in particular the multiple door leaf parts, for example two or three door leaf parts, can be connected to one another with the connection device so that together they form the door leaf, which can then be pivoted overall relative to the door frame in the working position.

The dust protection door can be formed in a simple manner when the connection device comprises at least one first and at least one second connection element which are arranged or formed on one of the plurality of door leaf parts and on another of the several door leaf parts and / or force and / or in the working position. or positively engage and are in the transport position disengaged. For connecting two door leaf parts, therefore, only the first and second connecting elements arranged or formed thereon must be brought into frictional engagement with one another and / or with a form fit.

The connecting device can be formed in a simple manner if it comprises at least one tightening fastener with a first connecting element in the form of a retaining projection and a second connecting element in the form of a tensioning bow, which at least partially engages behind or engages in the retaining projection in the working position. With such a connecting device, the door leaf parts can be coupled to one another in a simple manner. Furthermore, the securing device of the coupling device of the door frame can be dispensed with if the several door leaf parts are secured with the connecting device in the working position. At the same time, they also secure the interlocked door frame parts in the working position.

The connecting device can be formed in a simple manner if the at least one first connecting element in the form of a connecting projection and if the at least one second connecting element in the form of a connecting receptacle for positively and / or positively receiving the at least one connecting projection.

It is advantageous if the at least one connection receptacle is designed in the form of an opening, which in the working position interconnected door leaf parts or formed on these projections aligned and when the connection projection is formed in the form of engaging in the working position in the aperture connecting pin. In particular, the opening may be formed in the form of a bore. The apertures may also be in the form of eyelets, which are arranged with mutually aligned longitudinal axes of the door leaf parts to be joined together. The connecting pin may for example be fixed to a chain on one of the two door leaf parts, so that it can not be lost during transport or when it is pulled out of the connection receptacle.

In a simple manner, the dust protection door can be opened or closed in the working position, if at least one pivot bearing is provided for the pivotable storage of each of the plurality of door leaf parts. In particular, two pivot bearings may be provided for each of the plurality of door leaf parts. The pivot bearings may in particular be arranged and designed in such a way that the door leaf part pivotably mounted on a door frame part can not be separated from it as intended. Alternatively, the pivot bearing can also be designed separable to separate the at least one door leaf part of the at least one door frame part, with which it is pivotally coupled in the working position, in the transport position.

The door can be formed in a simple manner if the at least one pivot bearing is designed in the form of a hinge joint or a door hinge. The at least one pivot bearing may be formed in two parts and separable or two-part and not dismountable. Not separable means in particular that the pivot bearing is separable only by destroying a cooperating pivot bearing parts coupling pivot bearing connection device.

In order to form a sufficiently stable dust protection door, it is advantageous if the door frame and / or the door leaf are at least partially formed of metal and / or plastic.

The dust protection door can be designed cost-effectively, in particular if the metal is steel or aluminum.

Preferably, the plastic is a thermoset or thermoset. In particular, the plastic may be polypropylene or hard polyvinyl chloride. The closure element may in particular be made of polyethylene, for example in the form of a polyethylene film.

So that the dust protection door can be easily positioned and mounted, it is advantageous if it comprises a clamping device for clamping the door frame in the working position in the door frame or in the wall opening of the building. With the clamping device, the dust protection door can in particular be positioned and secured in a desired position in the door frame or in the wall opening. An opening remaining between the dust protection door and the door frame or the wall opening can then be closed in a dust-tight manner, for example, by a covering film. The cover film can be glued in particular on the door frame and the door frame or the wall opening with tape.

It is advantageous if the clamping device comprises at least one movable clamping element which is mounted on the door frame extendable from a basic position in a clamping position and which comprises a clamping surface facing away from the door frame for applying to the door frame or the wall opening of the building. Thus, the door frame between a floor of the building, so in particular a section against a lintel of the door frame or a fall of the wall opening, and the lintel or the fall of the wall opening clamp.

Preferably, at least one clamping element receptacle for movably supporting and guiding the at least one clamping element is arranged or formed on the door frame. In particular, the at least one clamping element can be inserted into the clamping element receptacle and partially moved out of this, in order to clamp the door frame in the door frame or the wall opening. In particular, the clamping element receptacle can define a stop for the at least one clamping element on which the clamping element can be supported. The stop can act in particular in the same direction in which the clamping surface of the at least one clamping element has.

For transport, it is advantageous if the dust protection door comprises a transport container for transporting the disassembled in the transport position into its multiple door leaf and door frame parts or folded dust cover door. In the transport container, the dust protection door can be transported easily and safely. In addition, it is also protected against damage in the transport container.

Simple and inexpensive, the transport container can be in the form of a bag. The bag is preferably dimensioned so large that the dust protection door can be completely absorbed in the transport position in this. Optionally, individual pockets for individual door frame or door leaf parts of the dust protection door can be provided.
