Description

Technical area

The invention relates to a device according to the preamble of claim 1.

State of the art

Such devices are already known and used in a wide variety of forms and designs. For example, in the DE 7315419 U discloses a portable separating stand, which is used to separate and cut to length closed profiles, in particular pipes, by means of cutting electric motor-driven or pressure-medium-operated hand tools, preferably angle grinders. Furthermore, in the DE 20 2011 110 548 U1 discloses a guide carriage for an implement, in particular a power cutter. From the DE 1 857 844 U an attachment device for an angle grinder is known with which the hands-free handling of the angle grinder, in particular for cutting purposes, is improved.

With a cutting stand such as the one mentioned above, handling and work safety when operating an angle grinder or angle cutter or separator can be improved. A separating stand makes such separating tools a stationary device, which is therefore not suitable for variable work, such as. B. for those that are suitable for the processing of tiles, tiles, or other objects to be cut on site such as profiles or pipes of any type and material. In addition, a lot of dirt or dust is created by the chips and falling products when cutting and separating materials. This is a problem in particular in the case of mobile processing on site, since it is mostly households that are to be contaminated as little as possible with dust or the like.

Object of the invention

The object of the present invention is to overcome the disadvantages of the prior art. In particular, a device is to be provided which enables a work device that can be operated by hand, such as For example, to guide an angle grinder, an angle cutter or another cutting or drilling device in such a way that, on the one hand, work safety not only guarantees but also increases and, on the other hand, mobile, precise and clean on-site handling of the material to be processed and built with the work devices is essential improved. The aim is to ensure that only the material to be processed is processed and that no processing marks and / or processing damage to other objects, for example a floor or a table, arise. Furthermore, it should be ensured that the environment is exposed to as little damage as possible with chips or dusts that arise from the processing of the materials.

Solution of the task

The features of claim 1 lead to the solution of the problem.

Advantageous embodiments are described in the subclaims.

The device according to the invention is a work pad for a work device that can be operated by hand. A work device that can be operated by hand means in particular angle grinders, angle cutters, cutting devices, saws, drills or similar devices with an electric motor or pressure medium-operated drive or hand tools operated with muscle power, such as hand saws or hand drills.

The work pad has a first support surface and a second support surface on an upper side. The top is the side of the work surface that faces away from a floor, table top or the like when used properly. These bearing surfaces also have a profile surface that prevents or significantly minimizes slipping of the materials to be processed. Furthermore is on one of the support surfaces a measuring mark is preferably arranged with a centimeter unit, so that the materials to be processed can easily be measured or measured on site. Of course, the specified units can also be changed, for example in inches. The materials to be processed are placed on the support surfaces.

A cutting trough is arranged between the two support surfaces. The cutting trough forms a channel-shaped formation between the two bearing surfaces, which runs parallel to a first longitudinal side or parallel to a second longitudinal side of the work surface. If a material is to be cut through or drilled, for example, it is positioned over the cutting trough by placing it on one or both support surfaces so that after the material has penetrated with the cutting or drilling element of the tool, it can dip into the cutting trough. This ensures that the work surface, but in particular not an existing work surface, such as a table or a floor, is damaged. In addition, the working document allows simplified and safe handling of the tools.

The cutting trough consists of a first cutting trough wall that runs orthogonally to the top or the first support surface and an opposing second cutting trough wall, which in turn runs orthogonally to the top or the second bearing surface, and a cutting trough bottom that connects the two cutting trough walls.

One of the two cutting recess walls has a suction opening. This suction opening represents a passage from the cutting trough to the underside of the work surface and enables a vacuum cleaner hose or a suction device to be connected there, which is used for suctioning off sawdust or drilling chips and dust. The suction opening has exchangeable adapter elements, which allow it to be easily Way to connect different suction devices or their hoses to the suction opening.

The cutting trough forms a first cutting trough recess or an opposite second cutting trough recess on the head or the opposite foot side, that is to say a first transverse side and an opposite, second transverse side of the work surface. These identical cutting recess recesses have approximately 50 percent of a cutting recess depth, preferably 30 to 70 percent. The cutting recess depth means the distance that extends from the top or the support surfaces to the cutting recess bottom. The advantage of these cutting recess recesses is that, in particular during a cutting or sawing process, the material does not first have to be cut from above in order to carry out the desired separation, but can be driven into the material from the side by sawing or cutting, with the material positioned in this way that this process takes place exactly at one of the cutting recess recesses. In addition to the work safety, this increases the precision in particular, since it is easier to adhere to the correspondingly specified cutting and / or sawing dimensions.

A cover recess runs around the entire cutting trough on the upper side or the support surfaces and the transverse sides along the cutting trough recesses. This cover recess forms a degree which is exactly as deep as the thickness of a first, second, third or fourth cover to be arranged there. The cover recess comprises a first and second cover recess groove on both sides of the cutting trough, in each case parallel to the bearing surfaces or the two longitudinal sides.

The cover recess and cover recess groove each form a receptacle for two covers, namely a first, a second, a third and / or a fourth cover.

On the underside, in each case at the corners between the respective long side and the respective transverse side, the work mat has corner feet. These corner feet have reinforcements in the form of corner foot lamellas, which are arranged bisecting the angle of the respective corner feet. This significantly increases the resilience of the work surface and prevents the corner feet from buckling, even under the heaviest loads.

In addition to the corner feet, the work mat has cross-bases on its underside, which are arranged on the underside of the cutting recess floor. The star bases further increase the support or standing area of the work surface and, thanks to the cross-shaped shape, prevent the work surface from slipping unintentionally during use.

Furthermore, on the underside of the work surface, stability lamellae are arranged orthogonally to the cutting cavity, which increase the stiffening and torsional strength so that the bearing surfaces can withstand the highest loads.

Each of the covers already mentioned has two cover springs running parallel to one another on the side which, when used properly, is directed towards the cutting trough. These cover springs have clamping beads arranged at regular intervals on the side.

The lid springs with the clamping beads allow the respective lid to be connected to the work surface via a clamp and plug connection. The cover springs on the underside of the cover engage in the cover recess grooves of the cover recesses. As a result, the cover thus received closes with its cover plate at the same height as the From the top of the work surface or the support surfaces and closes the cutting trough to 50 percent, as the lids close exactly half of the cutting trough due to their size. Another lid is then used to close the remaining 50 percent of the cutting cavity.

The different lids fulfill many tasks and lead to several significant advantages in connection with the work sheet. For example, the lid can be used to reduce the size of the cutting cavity and adapt it to the respective work with the hand-held device or the material. The individual covering of the cutting trough with the different lids serves the following purposes: a simple transport of the work document even after the dust has been picked up, a collection and storage of the dust created by the drilling and cutting work if no suction device is connected, an increased and especially more targeted one Suction performance if a suction device is connected and an individual adaptation of the work surface to the material and hand tools to be processed.

The differently designed covers belonging to the work sheet according to the invention enable the cutting trough to be closed or partially closed, which is particularly useful for collecting and sucking off the dust produced by sawing or drilling the materials to be processed.

The basic shape of the lid is L-shaped. All covers have the cover springs already described with the clamping beads. In addition, the lids all have a handle, which is arranged on a side plate of the lid. If the cover is used properly, the side plates of the respective cover close the area of the cutting recess.

The first cover has a closed cover plate and is used to completely close the cutting trough, with the complete Closing two first lids are needed. This is particularly advantageous for transporting the work document before and after use. In particular after use and if no suction device could be connected, the collected dust in the cutting trough can easily be transported away and disposed of at a suitable location.

Of course, it is also possible to use a one-piece cover to cover the cutting trough, which cover has the shape of two covers that are joined together and required for covering. This also applies to all other cover designs.

The second cover has a non-continuous saw slot in the cover plate. This significantly reduces the size of the cutting trough, so that a large part of the dust or sawdust fall into the cutting trough and can be collected or vacuumed there. This second cover is particularly suitable for sawing and cutting work, since it enables the tool to intervene when the material to be processed penetrates through the saw slot into the cutting cavity.

The third cover also has a non-continuous saw and drill slot, which, however, is additionally characterized in that a circular recess is arranged on the saw slot. For sawing materials, this circular recess also enables holes to be drilled that extend beyond the width of the saw slot.

The fourth cover has a continuous saw opening on its cover plate which, when properly inserted into the work surface, widens or expands in the direction of the respective transverse sides of the work surface or the side plate of the cover to the full width of the cutting trough or the cutting trough recesses. This means that the saw opening also broadens the cutting recess recesses on the transverse side of the work surface, which are otherwise covered by the side plate Share freely there. This shape is particularly advantageous when using cut-offs or jigsaws for cutting curves or non-straight cutting and separating lines and for laterally cutting into the materials to be processed without having to cut / drill into the material from above.

Of course, it is provided that the different covers can be combined on the working document depending on the requirements at hand. For example, it is quite advantageous to combine the first cover with the fourth cover, or the second cover with the third cover, so that the cutting trough can be adapted to the present requirements, to the tool and the material to be processed. Of course, any combination of the covers mentioned is possible with one another, even in a one-piece variant. It can also be provided that only a cover or no cover is arranged on the work surface. Of course, the working document according to the invention also includes further cover shapes, it being possible for example to change the width, length and shape of the saw slots or saw openings.

Furthermore, it is provided in preferred exemplary embodiments that the work pad according to the invention has a swivel arm recess on its second longitudinal side. A movable swivel arm is positioned in this swivel arm recess, which is connected to the second support surface via a swivel arm joint in the area of a corner foot. The swivel arm also has a swivel arm base which, when used properly, is in contact with a floor or a worktop or the like. In the unfolded position, the swivel arm is used to enlarge the second support surface for the material to be processed, so that when processing larger materials, there is no tilting and therefore inaccurate walking as a result of insufficient support surface or support points. The swivel arm can be spread out in the shape of a circular arc from the second long side, as with a compass and positioned at any position during this movement. After use, the swivel arm can be swiveled back into the swivel arm recess provided for this purpose and can be clipped or locked there or on the swivel arm joint via a clip connection or the like.

Of course, the pivot arm can also be arranged on the opposite first longitudinal side of the first support surface. It is also possible to arrange two corresponding swivel arms with two corresponding swivel arm recesses both on the first longitudinal side and on the opposite second longitudinal side. In addition, the pivot arm can have an additional joint in its center, which lies between the pivot arm joint and the pivot arm base, which further increases the mobility of the pivot arm. This has the further advantage that the additional support points that are formed by the swivel arm can be precisely adapted to the material to be processed and its size.

Embodiment

In Figure 1 a work pad 1 according to the invention is shown in a plan view of an upper side 2. On its upper side 2, the work pad 1 has a first support surface 4 and a second support surface 5, which are separated from one another by a cutting trough 6.

The two support surfaces 4 and 5 also have a profile surface 21 which prevents the materials to be processed from slipping. The profile surface 21 in the present case has a box pattern. Of course, other patterns are also provided for such a profile surface 21 and possible. Furthermore, a measuring mark 22, preferably with a centimeter unit, is arranged on the second support surface 5.

The cutting trough 6 is arranged between the first support surface 4 and the second support surface 5. The cutting trough 6 forms a channel-shaped formation between the two support surfaces 4, 5, which runs parallel to a first longitudinal side 7 or parallel to a second longitudinal side 8 of the work surface 1.

The cutting trough 6 consists of a first cutting trough wall 16 which runs orthogonally to the top 3 or the first support surface 4 and an opposite second cutting trough wall 17, which in turn runs orthogonally to the top 2 or the second bearing surface 5, as well as a cutting trough bottom 23, which the two Cutting recess walls 16, 17 connects to one another.

In Figure 2 it can be seen that the second cutting recess wall 17 has a suction opening 37. This suction opening 37 is circular and represents a passage from the cutting trough 6 to an underside 3 of the work surface 1. A suction device can be connected to the suction opening on the underside 3.

A first transverse side 9 and an opposite, second transverse side 10 of the work surface 1 run orthogonally to the two longitudinal sides 7 and 8 out.

These identical cutting recess recesses 12, 13 have approximately 50 percent, preferably 30 to 70 percent, of a cutting recess depth 38. The cutting recess depth 38 means the distance which extends from the top or the support surfaces to the cutting recess base 23.

A cover recess 14 runs around the entire cutting trough 6 on the upper side 2 or the bearing surfaces 4, 5, the transverse sides 9, 10 and along the two cutting trough recesses 12, 13. This cover recess 14 forms a circumferential degree 40 which is exactly as deep as the thickness 39 of a first cover 24, second cover 25, third cover 26 or fourth cover 27 to be arranged there. The covers 24, 25, 26, 27 are in the Figures 6 to 13 shown and described.

The cover recess 14 comprises a first cover recess groove 15.1 and a second cover recess groove 15.2 on both sides of the cutting trough 6 in each case parallel to the support surfaces 4, 5 or the two longitudinal sides 7, 8. The cover recess 14 with the first and second cover recess grooves 15.1, 15.2 form a receptacle for two covers 24, 25, 26, 27 in each case.

In Figure 3 a side view of the second longitudinal side 8 of the work pad 1 according to the invention is shown. Stability lamellae 18 can be seen, which are connected to the cutting trough 3 on the underside 3 and contribute to reinforcement of stability.

In the Figure 4 a side view of the second transverse side 10 of the work sheet 1 according to the invention is shown. The cutting trough 6 and the second cutting trough recess 13 can be seen. Furthermore, the cover recess 14, which forms the degree 40 and runs around the cutting trough 6, can also be seen here. Stability lamellae 18 are partially visible on the underside 3.

In Figure 5 the work pad 1 according to the invention is shown in a perspective view of the underside 3. On the underside 3, in each case at the corners between the respective long sides 7, 8 and the respective transverse side 9, 10, the work base has corner feet 11.1, 11.2, 11.3, 11.4. These corner feet 11.1, 11.2, 11.3, 11.4 have corner foot lamellae 19.11, 19.2, 19.3, 19.4 which are arranged bisecting the angle as reinforcements in the form of triangular struts in the respective right-angled corner of the respective corner feet 11.1, 11.2, 11.3, 11.4.

In addition to the corner feet 11.1, 11.2, 11.3, 11.4, the work pad 1 has cross-bases 20.1, 20.2 on its underside 3, which are arranged on the underside of the cutting recess base 23. The underside of the cutting recess base 23 means the side that lies on the underside 3 and, when the work surface 1 is used properly, is in contact with a base, for example a floor or a table top. The star bases 20.1, 20.2 increase the support or standing surface of the work surface 1 and, due to the cross-shaped shape, prevent the work surface 1 from slipping unintentionally during use.

Furthermore, the stability lamellae 18 are arranged on the cutting trough 6 on the underside 3 of the work surface 1, which increase the stiffening and torsional strength so that the bearing surfaces 4, 5 or the work surface 1 withstand or withstand the highest loads.

In Figures 6 and 7 the first cover 24 can be seen. The first cover 24 consists of a closed cover plate 32 and a closed side plate 33 adjoining it at right angles. The basic shape of the first cover 24 is therefore L-shaped. A handle 30 is also arranged on the side plate 33.

On the underside of the first cover 24, two cover springs 28 are arranged longitudinally and parallel to one another. Clamping beads are arranged on the cover springs, which enable the clamping or plug-in connection with the cover recess grooves 15. In the case of the first cover 24, as well as the other covers 25, 26, 27, are on a cover spring on both sides five clamping beads 31 each arranged at regular intervals. Of course, the number can be changed in other versions.

Furthermore, the first cover 24 has three cover lamellae 29 on the underside. These cover lamellae 29 connect the cover plate 32 to the side plate 33 and increase the torsional stiffness of the first cover 24. With the underside of the first cover 24 and all other covers 25, 26 described below , 27 the side is meant which, when used properly, that is to say when it is inserted into the work surface 1, faces the cutting recess 6 due to the interlocking of cover recess grooves 15 and cover springs 28.

In the Figures 8 and 9 the second cover 25, also with a view of an upper side and a lower side, is shown. An essential feature that separates the second cover 25 from the first cover 24 Figures 6 and 7 A distinction is made that the second cover 25 has a cover plate 32 which is partially split by a saw slot 34. The saw slot runs in the middle of the cover plate parallel to the two cover springs 28 and ends in front of the cover slats 29 and the side plate 33. By inserting the second cover 25 with the saw slot 34 into the work surface 1, the cutting trough 6 is significantly reduced in size or in this area . constricted.

In the Figures 10 and 11 the third cover 26 can also be seen from an upper side and a lower side. In contrast to the second cover 25, the third cover 26 does not have a saw slot 34, but a saw and drill slot 35. This differs in that it has a circular recess in the area that faces the side plate 33. This recess makes it possible to saw a curve during a sawing process or, in particular, to drill materials with a stronger drill. Apart from the sawing and drilling slot 35, the third cover 26 corresponds to the first cover 24 or the second cover 26.

In the Figures 12 and 13 the fourth cover 27 can also be seen from two perspectives, namely from an upper and a lower side. The fourth cover 27 has a saw opening 36. This saw opening 36 divides the cover plate 32 completely. The saw opening 32 widens in the region in which the cover plate 32 is connected to the side plate 33 in a funnel-shaped manner. After it has enlarged in the shape of a funnel, the saw opening also extends to the side plate 33. For this reason, the fourth cover 27 has no cover lamellas 29 on its underside.

Furthermore, for this reason, too, the handle 30 is no longer arranged centrally on the side plate as in the other covers 24, 25 and 26, but in a lower area of the side plate 33, the lower area being the area that extends from the cover plate is turned away. The saw opening 36 of the fourth cover 27 enables, for example, a saw to move laterally into the materials to be processed via the first or second cutting recess 12, 13 of the cutting recess 6. Of course, the fourth cover 27 also has corresponding cover springs 28, just like the first, second and third lids 24, 25 and 26.

In the Figure 14 the working document 1 according to the invention is shown. The cutting trough 6 is covered by two second covers 25. The two saw slots 32 of the two second covers 25 merge into one another with an exact fit. Of course, the illustrated second covers 25 can also be replaced by other covers 24, 26 and 27.

In the Figure 15 the working document 1 according to the invention is also shown. Only one cover 25 is arranged in the cover recess 14, so that half of the cutting trough 6 is exposed and uncovered. Of course, any of the mentioned covers 24, 25, 26, 27 can be used here.

In Figure 16 a further exemplary embodiment of the work sheet 1 according to the invention with two second covers 25 is shown. This embodiment has a swivel arm recess 44 on its second longitudinal side 8. A movable swivel arm 41 can be positioned or folded in and out in this swivel arm recess 44, which is connected to the second support surface 5 via a swivel arm joint 43 in the area of a corner foot 11.4. The swivel arm 41 has a swivel arm foot 42 which, when used properly, is in contact with a floor or a worktop or the like.

The pivot arm 41 is used in the unfolded position, that is, in a position in which it is not hidden in the pivot arm recess, to enlarge the second support surface 5 for the material to be processed. The swivel arm 42 can be spread or positioned in the form of a circular arc from the second longitudinal side 8, as in the case of a compass. This is shown by both arrows 45.1 and 45.1. After use, the swivel arm 42 can be swiveled back into the swivel arm recess 44 provided for this purpose and can be clipped or latched there or on the swivel arm joint 43 via a clip connection or the like, not shown.

Referring to the Figures 1 to 16 the mode of operation of the working document 1 according to the invention is explained as follows:
In particular with tiles, but also with other materials to be processed that require individual cutting or drilling, there is the problem that a work sheet or a work area for the manually operable tool is usually not on site, i.e. not at the place where the materials are processed Need to become. A constant change of position is therefore necessary, namely from the point at which the material to be installed is measured and later installed and the point at which it can be processed.

When cutting, drilling or other processing of, for example, tiles or other materials such as drainage pipes or the like on site, there is often a lack of a suitable base which prevents accidental cutting or drilling into the ground or into another unsuitable base. Injuries are also often caused by the fact that work is carried out in an improper manner, i.e. without a suitable surface on site, for example on a bathroom floor when cutting tiles. This increases the risk of injuries through improper work enormously, because the working person is focused on not damaging the floor or the otherwise unusable surface during a cutting or drilling process. Furthermore, the chips and dusts produced during drilling, cutting or sawing are not collected, but are distributed on site, which leads to considerable contamination of the work site and not least to contamination of the breathing air.

If a material to be processed is positioned on one or both of the support surfaces 4 and 5 of the work surface 1, it spans the cutting trough 6. The cutting trough 6 can be used for the desired operation and that by means of the different covers 24, 25, 26 and 27 and their combination with one another the tool to be used. If, for example, saw widths are necessary that provide for frequent changes of direction, it is advisable to insert the fourth cover 27 in connection with, for example, the first cover 24 in the cover recess 14. If primarily drilling is necessary, it is advisable to use the third cover 26, which has the sawing and drilling slot 35.

The dust and chips that are produced are suctioned off via the suction opening with a suction device to be connected there from the underside 3, for example a conventional vacuum cleaner with a corresponding suction hose. It is provided here that different and exchangeable plug and click connections are arranged on the work surface 1 or the suction opening 37, so that different Suction device can be connected. This relates in particular to different diameters and the shape of the end pieces of the suction hoses, so that the usual sizes and shapes can be connected here.

In order to enable a particularly good suction result, especially of heavier chips, for example made of metal, it is advantageous if the cutting trough 6 is covered, if possible, by two covers 24, 25, 26, 27 so that the suction power can be optimally used.

Furthermore, the work pad 1 according to the invention can also be used without a suction device. The chips and dust are then collected in the cutting trough 6, which can later be emptied. If no suction device is connected, a simple plug (not shown) or a flap closes the suction opening 37.

At the measurement marking 22, measurements can be taken in a simple manner by placing the materials to be processed.

Furthermore, the swivel arm 41 which can be swiveled out of the swivel arm recess 44 serves to create additional and flexibly positionable support points for larger materials.

Although only a few preferred exemplary embodiments of the invention have been described and illustrated, it is obvious that numerous modifications can be added by those skilled in the art without departing from the spirit and scope of the invention. In particular, further and one-piece cover designs are conceivable and provided. However, changes which affect the profile surface 21 and its shape or design are also included. Of course, the covers 24, 25, 26, 27 can also have a corresponding profile surface. <b> List of reference symbols </b> 1 Working document 34 Saw slot 2 Top 35 Saw and drill slot 3 bottom 36 Saw opening 4th first contact surface 37 Suction opening 5 second support surface 38 Recess depth 6 Cutting trough 39 Lid thickness 7th first long side 40 Degree 8th second long side 41 Swivel arm 9 first transverse page 42 Swivel arm base 10 second transverse page 43 Swivel arm joint 11 Corner foot 44 Swivel arm recess 12 first cutting recess 45 Arrows swivel directions 13 second cutting recess 46 14th Cover recess 47 15th Lid recess groove 48 16 first cutting recess wall 49 17th second cutting recess wall 50 18th Stability slats 51 19th Corner foot slats 52 20th Base 53 21st Profile surface 54 22nd Measurement marking 55 23 Cutting recess bottom 56 24 first lid 57 25th second lid 58 26th third lid 59 27 fourth lid 60 28 Lid spring 61 29 Lid slats 62 30th Grab handle 63 31 Clamping bead 64 32 Cover plate 65 33 Side plate 66
