Description

"Protective device"

The present invention relates to a protective device for use in construction work, renovation or repair work, in particular on a building, with a covering device and with a connecting means, wherein the connecting means with a building part or an object is releasably connectable.

When construction work, renovation work or repair work is carried out by painters, electricians or drywall workers on a building, a high level of dirt, dust or paint mist is generated. The removal of a wall, the slitting of channels in the wall plaster for laying new pipes, the sanding of parquet or the application of paint are examples of the work associated with the development of dirt, dust or paint mist in connection with buildings. The aforementioned work can also be outside of buildings occurrence, for example, in relation to motor vehicles or outdoor objects, such as garden furniture, event modules, are applied. In this context too, the protective device is relevant.

Parts of the building that are not involved in the work or objects in the building or outside a building must be protected from dust and dirt or from paint mist. Adjoining rooms must, if necessary, be sealed in a dust-tight manner, for which wall openings are covered with a film, which is cut from the roll on site and which is glued to the frame surrounding the wall opening with adhesive strips that have also been cut on site. Building surfaces, such as floors or doors and windows are also taped with foil. Even in the rooms or outside buildings located objects are covered with films and the

confirmation copy Foil is fixed to the suitable substrate by means of adhesive tape. In addition to foils can also be used Malervlies.

A considerable proportion of the work of the corresponding specialist personnel is therefore no longer necessary for the protective measures and requires a great deal of personnel and time. In addition, the protective measures are labor-intensive and are part of the preparation area, which the customer has to pay dearly, while the actual paint, electrical installation or drywall construction has not even begun. The relationship between preparatory work and actual construction work can be improved in terms of time and costs. In addition, results in the removal of the known protection device, a high waste volume, which pollutes the environment. In addition, the adhesive strips known from practice often leave behind adhesive traces which are difficult to remove and which must be removed in a complicated manner and can damage the surface of an object or parts of buildings.

The invention has for its object to provide a protective device of the type in question, which reduces the cost and time of construction, renovation or repair work and protects the environment.

The above object is solved by the features of claim 1. According to claim 1, a protective device of the type in question is designed and developed such that the connecting means is magnetic and that the building part or the object is at least temporarily - during interaction with the magnetic connecting means - ferromagnetic. First of all, it has been recognized that the protective device known from practice is carried out manually by skilled personnel manually by cutting film and adhesive tape from rolls, removing the adhesive protective film and attaching the film with the adhesive tape to the building part or object is and thus time consuming and costly. Furthermore, it was recognized that after the removal of the protective device mountains of garbage arise. According to the invention, it has been recognized in a first step that the connection means are to be changed if the basic properties of covering devices are to be maintained. According to the invention, it has also been recognized instead of using a known adhesive tape as a connecting means to use a magnetic connecting means. The magnetic connection means can interact with ferromagnetic building parts or objects per se. For example, ferromagnetic frames for doors, radiators or electrical boxes are used in most public buildings, where the protective device according to the invention can be magnetically fixed. Likewise, reinforcement elements within drywall, elevators, metal doors, distribution cabinets, hydrant boxes are ferromagnetic. In addition, mobile metallic office furniture or metallic storage units that have the required ferromagnetic properties.

Furthermore, it has been recognized according to the invention that building parts or objects without ferromagnetic properties can be temporarily equipped with ferromagnetic properties, namely for the period in which the covering device and its magnetic attachment has to be effective. For example, ferromagnetic aids, such as strips or angles, can be applied and removed again after completion of the work. Finally, it has been recognized according to the invention that the protection device according to the invention in question is then environmentally friendly, if a multiple applicability is made possible. This is achieved precisely by the magnetic connecting means according to the invention. The entire covering device, including the connecting means, can be brought to the next place of use after use and can be fastened easily and at high speed to the building part or to the object. Another advantage of the magnetic connection can be seen in the fact that no adhesive residues remain as in the prior art and therefore no post-processing effort arises and surface damage can largely be ruled out.

Depending on the shape of the building part or of the object, the covering device of the protective device according to the invention could comprise a flexible material, in particular a foil, or a rigid plate or a three-dimensional, rigid component. Especially with wall openings that are to be closed, could be used with a polyethylene film or with fleece. Wells could be filled with moldings made of foam. Plate material or hood-like or U-shaped constructs can also be used to form covering devices. Another alternative provides for the use of self-stiffening material which is space-saving in the idle state and stiffenes itself in the operating state, for example via spring steel strips. The flexible material could be surrounded by a rigid frame or by a frame of self-stiffening material, the latter protection device could be rolled up in an advantageous manner. What is common to all capping devices is that they have the magnetic connection means. If the protection of the adjacent room is desired, the covering device of the protective device according to the invention could cover the frame and the wall opening. The magnetic connecting means could be arranged circumferentially or on the longitudinal sides on the covering device and approximately correspond in terms of dimensions to the wall opening to be closed. According to a particularly preferred embodiment, in the case of a rectangular covering device on the longitudinal sides and on the upper transverse side of the magnetic connection means may be arranged, while at the bottom an adhesive could be provided, which enters into an autostatic connection with the ground, thereby forming a slightly adhesive seal to the ground.

With a covering device of the protective device according to the invention formed in a U-shaped manner, at least in the operating position, for example, a ferromagnetic steel sheet frame could be covered and effectively protected on its visible three sides. A frame usually includes a wall opening in the form of a door. The U-shaped covering device could have flat magnetic connecting means on the inner sides or have at the free ends of the U-legs angled regions whose depth corresponds to the depth of the wall projecting from the frame.

The protective device according to the invention, which is present as a frame protector, allows for various advantageous designs. Thus, the U-shaped component could be rigid, but at the angle ranges between U-leg and U-base have flexible areas, so that the jaw width of the frame protector to the actual and depending on the construction site repeatedly varying dimension of approximately the wall thickness corresponding Zargentiefe can be adjusted. With regard to a particularly preferred embodiment of the frame protection, which allows the maximum freedom of the foot protection variability, this could by a Foil or a fleece are formed, which is simply wrapped around the frame and adapts to each Zargentiefe. In operation, the frame protection film also assumes a U-shape, due to the frame shape. With regard to transport or storage, both frame protection variants have their advantages - on the one hand, the upright, stackable rigid U-shape with a long service life, on the other hand, the foldable or rollable film.

On parts of buildings or objects, for example, consist of wood and have no metallic components with ferromagnetic properties, ferromagnetic aids could be arranged, which then interact with the magnetic connection means of the cover. As an aid, for example, bracket-like components are considered, which are attached to the object or the building part and thereby, for example, the residual stress comes into play. Furthermore, it is also possible to apply planar or angular ferromagnetic aids. The tools could also be magnetically independent, in which case the correct polarity with regard to the magnetic connection means of the covering device should be taken into account.

The magnetic connection means of the protective device according to the invention could preferably be a magnetic strip. Flexible magnetic strips could, for example, be attached to the covering device on the covering device on site. For example, the magnetic strip could have an adhesive surface and a magnetic surface, wherein the adhesive surface is brought into connection with the covering device, in order then to connect the covering device to the ferromagnetic, metallic building part, object or ferromagnetic aid via the magnetic surface.

As an alternative to a flexible, flat or slightly curved in cross-section magnetic strip as a connecting means on the cover could also rigid, magnetic connection means are used, which could be advantageous in terms of an upright and space-saving storage. But also covering devices in the form of foils equipped with flexible magnetic strips can be accommodated in a space-saving manner when rolled up. Here it depends on the demand of the consumer. The storage plays a role in terms of reuse of the inventive protection device to the benefit of the environment.

A preferred embodiment of the protective device according to the invention provides that the magnetic connection means have at its contact surface to the building part or to the object a protective layer for protecting the surface of the building part or the object. This means that particularly fragile, finished building parts and particularly sensitive, finished objects located in or outside the building remain undamaged. Even when using a ferromagnetic aid, the advantageous protective layer has a positive effect on its longevity and aesthetics.

According to a particularly preferred embodiment of the protective device according to the invention, the magnetic connecting means could be an integral part of the covering device.

On the one hand, this could be realized by prefabricating the covering device and the magnetic connecting means in the preparation of the protective device in advance, outside the construction site. The prefastening could involve making a material bond between the capping means and the magnetic bonding means. In addition to adhering a magnetic strip, magnetic connecting means could also be sewn into the covering device, welded, inserted or clipped onto it. There are many possibilities These include, for example, the incorporation of depressions, compartments or pockets into the covering device, into which magnets or magnetic connecting means are preferably inserted in a captive manner.

On the other hand, the use of magnetized materials, such as magnetized foils or plates, could make the magnetic connection means an integral part of the covering device. Although the initial investment cost of magnetized materials is comparatively high, it can pay for itself through the number of reuses, particularly in the commercial aspect of leasing such high-quality guards to various construction companies.

With regard to a frequently required embodiment of the protective device according to the invention, which is suitable for closing wall openings and covering the frame surrounding the wall opening, a preferred embodiment provides that the covering device and the connecting means are prefabricated and more customary in different standard sizes Frame dimensions for wall openings are available. Such dimensions could correspond to the specifications of DIN standards for frames, door leaves, clearance dimensions, nominal dimensions or structural dimensions, which result, for example, from DIN 18100, DIN 18111, DIN 18101. The protections to be provided could be such as to cover wall openings and frames with the following frequently used dimensions:

Nominal wall opening (single-leaf door) External frame dimensions

Width x height width x height

[mm] [mm]

750x 2005 776x2043

760 x 2130 776 x 2168

885 x 2005 901 x 2043

885 x 2130 901 x 2168 1010 x 2005 1026 x 2043

1010 x 2130 1026 x 2168.

Corresponding to the standard sizes reproduced above, protective devices could be offered in the hardware store which are magnetically adhered to the ferromagnetic frame in the simplest manner during construction activities and thus achieve the desired protective effect in the shortest possible time and without great effort. The protective devices described above could, with regard to the cover device, consist of a flexible sheet material and the magnetic connection means could be flexible or rigid. It could circulate like a frame continuously or discontinuously at the edge region of the covering device. In any case, the protective device in question could be brought into a folded or rolled or folded storage or transport position.

In addition to protective devices for wall openings and frames, such protective devices could also be displaceable into space-saving storage or transport positions which deviate from flat or U-shaped operating positions depending on the different types of covering device for a wide variety of objects or building parts. Also conceivable are kits for multi-unit protective devices or small transport and storage formats of self-stiffening cover devices, which are offered as a sales format and can be used in use on an operating position of the desired size. The protective device according to the invention could be further adjusted in size to be covered building part or object or tool or wall opening to be closed. In other words, the protective device according to the invention could be further developed so that both in the transport and storage position and in the operating position desired dimensions can be set defined by folding, Teleskopierbar- and other measures. There are now various possibilities for designing and developing the teaching of the present invention in an advantageous manner.
