Definitions

• the invention relates to a device and method for the temporary attachment of holding or fastening means to a surface which can have unevenness, use being made of the vacuum principle used in suction attachments.
• suction attachments are known which have a suction attachment connected to a vacuum pump which is placed on workpieces in order to be used as a load hook. Furthermore, suction attachments are known in connection with drilling devices, these suction attachments serving as device holders (DE 35 01 753, DOS 27 44 463). Out
• REPLACEMENT LEAF FR-PS 1595 727 a suction cup with a compressible cushion is known, which consists of porous rubber.
• vacuum holding devices which work with plate-shaped or cup-shaped suction elements which are provided with sealing lips or a sealing ring on their side opposite the workpiece to be picked up, the latter consisting of very soft, elastically deformable material and as a special, separate part formed and connected to the suction element (DE-AS 27 23 16).
• the object of these known devices is to hold or transport loads and to hold drilling devices.
• the prerequisite for the correct operation of these devices is that the surface of the loads to be transported is essentially flat, smooth, dense and homogeneous.
• the suction elements known from DE-AS 27 23 616 and FR-PS 1595.727 can also be used with a not completely flat base, but presuppose that a predetermined vacuum is always maintained.
• the invention has for its object to provide a vacuum working device for the temporary attachment of holding or fastening means, which can be attached to a surface, which may have unevenness and / or which is inclined, this device even after reduction or elimination of the negative pressure should have a sufficient holding force for a certain time.
• Such tasks occur continuously in industry, in crafts, but also in the private sector.
• it is a matter of creating a support for concrete formwork, fixing scaffolding, attaching it to a sloping roof tile or simply holding a freely laid cable at several places at the appropriate height.
• a device known from FR-PS 15 95 727 which consists of a fitting provided with a vacuum bushing, one side of which carries the holding or fastening means and the other side of which serves for sealing a closed bead made of compressible material is provided.
• the fitting is designed as a plane-parallel and rigid mounting plate, on the sealing side of which the bead is applied as a plastically deformable sealing compound.
• This holding plate can have one or more vacuum connections, which are in the plate plane or perpendicular to
• one or more limiters as spacers in the sealing side of the holding plate, the length of which should expediently be adjustable.
• existing internal threads made of metal parts can be used in the holding plate. B. serve the inclusion of these spacers.
• Such internal threads can also be provided on the outside of the holding plate in order to be able to fasten the holding members therein if necessary.
• sealing side of the holding plate can be provided with a surface structure which leads to an increase in the adhesive forces.
• This surface can be provided with milled ribs or simply sandblasted.
• Handle strips should be provided, which make it easier to attach or remove them from a surface. These grip strips or, if necessary, additional cutouts can be used to attach a corresponding tool when dismantling such a holding plate.
• the plastic polyisobutylene is expediently used as the plastically deformable sealing compound for the holding plate, the properties of which are ideal for the present purpose. This plastic, which is applied, for example, in the form of a bead as a border on the holding plate, can be easily removed from both the uneven surface and the holding plate without leaving any residue. This material is therefore easily reusable and can therefore be used for any number of times
• Holding plate can be used.
• it has the property that when the vacuum is created between the holding plate and the surface to which the holding plate is to be attached, the unevenness adjusts itself vacuum-tight.
• the unevenness adjusts itself vacuum-tight.
• Adhesion property results from the surprising effect that even after the vacuum existing between it and the uneven surface has been released, the holding plate is retained for a longer period of time, possibly several weeks, even under load. This holding effect can even be permanent.
• This surprising effect represents a significant advantage both over the known suction attachments mentioned at the outset, which work with sealing lips made of rubber or a rubber-like material, and also over those which, in accordance with FR-PS 15 95 727, are provided with a bead made of compressible, elastic material. If the vacuum is released in these known suction attachments, the object carried by the suction plate suddenly falls off.
• the invention is also not suggested by DE-OS 3425 853, which is to produce brackets or hooks on a flat wall by creating a vacuum between the bracket and the wall and then injecting sealant.
• This known holder can only be loaded after the sealing compound has hardened and therefore does not achieve the object on which the invention is based.
• the plastically deformable sealing compound can be preformed in its profile before it is applied to the holding plate, for which purpose an extruder can be used, for example.
• This profile can be designed similar to a sealing lip in order to achieve a quick seal.
• the application of the extruded profile to the holding plate is facilitated by using a guide body which is guided along a groove in the holding plate.
• the sealing compound is also applied as a closed border in the shape desired in each case to the holding plate. This shape can be chosen so that leaky areas of the substrate are excluded.
• the amount and cross section of the sealing compound can be adapted to the respective application in order to achieve the desired adhesive force.
• the sealing compound can be a so-called polar compound (use from -30 * to + 5 * C), standard compound (use from 0 * to + 40 * C) and tropical compound (use from + 15 * to +70 * C) choose.
• a combination of these masses is for certain uses possible.
• pressure or suction With the help of pressure or suction, the introduction of liquids or gases of different temperatures is advantageous for the purpose of easier assembly or disassembly.
• An essential advantage of the device according to the invention resulting from the use of a plastically deformable sealing compound is that it can be attached to an uneven surface in a self-retaining manner - by mechanical pressure - prior to the generation of the vacuum, because a toothing between the sealing compound and the uneven surface occurs.
• sealing compound which can be deformed on the table also offers the advantage that the vacuum seal of the holding plate can be improved at any time by additional sealing compound if there are still leaks.
• the use of diluted glue or paste can help to make the surface airtight without having to change the surface.
• the device consists in providing an additional vacuum container with a sufficient vacuum space between the required vacuum pump and the vacuum line penetrating the holding plate is switched on.
• This vacuum container which can be cylindrical and can be provided with one or more perforated partitions or circumferential outer ribs in order to maintain its rigidity, maintains the vacuum over a longer period of time even after the vacuum pump has been switched off.
• This vacuum container should be equipped with a liquid indicator and a drain valve for aspirated liquid.

Because the individual, made of airtight material through Air-permeable joints are limited, several closed beads lc made of plastically deformable sealing compound are first applied to the sealing side of the holding plate 1 in order to be able to produce a corresponding number of vacuum spaces after the holding plate 1 has been attached to the masonry 7.
