Description

Drilling dust collector to collect the dirt generated during the drilling process.

The drilling dust catcher is a utility item that should be used sensibly and in a variety of ways both in domestic use and in the professional sector.

Drilling dust collection devices of the usual type are

1. Electrically operated "mini vacuum cleaners" (see publication DE 40 30 A1 dated 26.03.1992) attached to professional drills and hammer drills which always require an electrical connection and work according to the suction principle.

2. Complex technical devices for collecting drilling dust, especially during rock drilling in mining (see publication 2330128 of 03.01.1974; file number 7846-72).

In addition, they are expensive to purchase and it is not possible to connect them to every drill.

Drilling always causes annoying dirt by dislodging puddles of material from the wall in question. This is particularly the case with non-load-bearing walls, which are generally made of soft, porous, relatively loose and therefore very dusty material.

When loose material particles fall down, the dust particles are stirred up by the concentrated air coming out of the drill's air outlet and are sometimes whirled several meters across the room. This is very unpleasant in private areas.

In commercial work areas, the uncontrolled distribution of dust and material particles can lead to the destruction of unrelated objects and machines. For example, falling material particles that are whirled through the air can be sucked in through ventilation slots on computer devices (always present to ensure ventilation of the computer) and then cause potentially irreparable damage to magnetic hard drives and similar sensitive objects.

In the medical field, an increased concentration of dust in the air, such as that which sometimes prevails several days after drilling operations, can potentially slow down the healing process. To prevent this, the rooms in question in hospitals are left empty for days. The result is a financial loss due to non-use.

The invention specified in claim 1 is based on the problem of creating an inexpensive and at the same time effective way of collecting drilling dust. This possibility must also work without the need for a power connection in order to be easy to transport, i.e. without additional effort.

The problem is solved with the features listed in claims 1 to 6:

1. Fastening directly below the drilling point.

2. Easy and quick installation.

3. Remove from the wall without leaving any residue.

4. Can be folded flat for storage and transport.

5. Can be reused by removing again.

The invention achieves that:

1. The effort required to avoid dirt is significantly reduced.

2. That the annoying removal of drilling dust, e.g. from behind radiators and furniture, is no longer necessary.

3. In the medical sector, ventilation is no longer necessary for days.

4. The use of electrical energy for removing dust becomes completely unnecessary.

5. Since the drilling dust collector can be made from 100% recycled material, it is also environmentally friendly.

6. Since one hand always had to be available to hold the auxiliary equipment when handling various makeshift tools (in the case of one-man operation), this has previously led to inaccuracies during the drilling process at best and accidents at worst. Now the drill operator can devote his undivided attention to the actual drilling process. Accidents resulting from the above reasons can be a thing of the past in the future. This results in a significant increase in occupational safety.

7. Efficient advertising medium due to the possibility of placing different advertising messages directly in front of the user’s eyes.

It is made from inexpensive paper. It remains to be seen whether the drilling dust collector can be made from cuttings that inevitably arise during the manufacture of other paper products. In any case, the drilling dust collector will not place any additional burden on the environment, despite the fact that it is a disposable item. It should be made from a material that decomposes without leaving any residue.

The shape of the drilling dust collector can be varied within certain limits. However, it is important that a sufficiently large recess (approx. 5 cm diameter) is provided for the drill (see Fig. 1 and Fig. 2, item 1). The side parts of the drilling dust collector that provide protection against swirling dust (see Fig. 1, item 5) must be higher than the recess for the drill hole (see Fig. 1, items 1 and item 5). In addition, it is important that the front of the drilling dust collector has a large recess.

(see Fig. 1 and Fig. 2, item 2). This is necessary to ensure that the drill chuck runs freely.

The front side can be used in many ways. The available space can be used as advertising space (see Fig. 1, item 6). However, it is also possible to print operating instructions for the use of, for example, dowels, drills, special screws, etc.

An exemplary embodiment of the subject matter of the invention will be explained below with reference to Figures 1 and 2

The drawings show in:

Fig. 1 An isometric view of the drilling dust collector Fig. 2 The rear view

Fig. 3 The rear view with a variant

Figure 1 shows the drilling dust collector in a ready-to-use state, i.e. unfolded and already attached to the wall, during use. The drilling dust collector has a round hole (item 1) for different drill diameters on the back (i.e. facing the wall). In addition, the drilling dust collector has a circular recess (item 2) for different drill chuck diameters on the front (facing the user).

Furthermore, it is clear that the drilling dust collector has a variable internal volume, which is achieved thanks to a fold according to the accordion principle (point 5) in order to ensure an optimal ratio between minimum transport volume and maximum dirt absorption.

The drilling dust collector is temporarily attached to the wall using a removable adhesive surface (Fig. 2, item 4).

The protective paper layer can be removed very easily using a grip tab (point 3). The protective paper layer consists of just one continuous piece of paper or film (see Fig. 2, points 3+4). This also makes it much easier to apply the adhesive when making the drilling dust collector.

An embodiment variant for the subject matter of the invention will be explained below with reference to Figure 3

Figure 3 shows another possible manufacturing variant in which the hole (point 1) on the back of the drilling dust collector can be manufactured as a semicircle.

Claims (4)

1. Drilling dust collector made of suitable material such as paper, characterized in that it is attached to the wall below a drill hole in order to collect as much of the dirt inevitably generated during the drilling process as possible. 2. Drilling dust catcher according to claim 1, characterized in that the drilling dust catcher is folded flat before use for easier storage and better transport and only has to be unfolded for the purpose of use. 3. Drilling dust collector according to claims 1 and 2, characterized in that it can be removably attached to the wall using a single or multi-layer adhesive surface (attached to the back of the drilling dust collector; see ( Fig. 2, item 4)). This adhesive connection is intended for temporary use so that it can be removed again without leaving any residue of the adhesive on the wall. Before use, the adhesive surface is protected against drying out with a protective paper. This protective paper is easily removed using a grip tab (see Fig. 1 and Fig. 2, item 3). 4. Drilling dust collector according to claims 1, 2 and 3, characterized in that it has a round recess of about 5 cm on the back for variable drill bits (see Fig. 1 and Fig. 2, item 1). A recess is provided on the front to give the drill chuck of a drill sufficient space for free rotation (see Fig. 1 and Fig. 2, item 2).
