Disclosure of the invention

One object of the invention is to reduce the effort involved in cutting panels.

This task is solved by the independent patent claims. Advantageous embodiments are shown in the dependent patent claims, the following description and the figures, whereby these embodiments, taken alone or a combination of at least two of these embodiments with one another, can represent an advantageous and/or further developing aspect of the invention.

A device according to the invention for cutting panels has at least one holding unit for holding a cutting tool for marking and / or cutting the panels, at least one straight profile, at least one adjustment unit which can be temporarily fixed to the profile in different positions relative to the profile, and at least one along one A first length measuring scale arranged on the profile extends along the longitudinal extent of the profile, wherein the holding unit is fixed to an end section of the profile and the first length measuring scale is arranged on the profile in such a way that an amount of main scale numbers of the first length measuring scale decreases starting from the holding unit in the direction of the setting unit and a cutting tool arranged on the holding unit is arranged at a first maximum dimension of panels to be cut, which is coordinated with the first length measuring scale.

If the length of a plate with a standardized maximum dimension of, for example, 200 cm is to be reduced to 180 cm in the length direction of the plate by cutting, for example, the device according to the invention can be used with the first length measuring scale, which can start, for example, at 130 cm, 140 cm or 150 cm . In order to be able to carry out a cutting and/or marking process with a cutting tool arranged on the holding unit with the device arranged on the plate to be cut, the first length measuring scale ends at its other end in front of the location at which the cutting tool can be arranged. Therefore, the first length measuring scale is arranged on the profile in such a way that the first maximum dimension of the panel to be cut is coordinated with the first length measuring scale, but is not physically given by the first length measuring scale or cannot be read from it. Instead, the first length measuring scale and the holding unit are arranged relative to one another on the profile in such a way that a cutting tool arranged on the holding unit is located exactly at the first maximum dimension of the panel to be cut, which is coordinated with the first length measuring scale.

In order to be able to carry out the desired cutting and/or marking process in accordance with the above-mentioned example with the device according to the invention, the adjustment unit is first displaced relative to the profile until a guide surface of the adjustment unit facing the holding unit is arranged at the value 180 cm of the first length measuring scale . In this state, the setting unit is then mechanically fixed to the profile. The guide surface of the adjustment unit is inevitably arranged exactly 20 cm away from the location at which a cutting tool arranged on the holding unit can be arranged. After arranging the cutting tool on the holding unit, the guide surface of the adjusting unit can be placed flat against an edge of the panel to be cut, so that the device for cutting and/or marking the panel can be guided along the panel by moving the guide surface of the adjusting unit along the edge the plate is guided. In the example mentioned above, the plate is cut and/or torn at a distance of 20 cm from the edge of the plate, so that the plate is or can be cut to the desired maximum dimension of 180 cm in the length direction of the plate. To do this, the user does not have to determine an amount of the length of the plate using mental calculations, but can directly set the desired width of the plate on the device and then Carry out cutting and/or marking. This prevents processing errors caused by calculation errors in particular, which reduces material waste.

In order to be able to carry out the desired cutting and/or marking process, a user does not need any other tool apart from the device according to the invention and the cutting tool arranged thereon, which greatly simplifies the implementation of the cutting and/or marking process for the user, which also increases the accuracy of the Process is increased and its repeatability is improved.

The first length measuring scale is preferably linearly divided. The first length measuring scale can be metric or, for example, an inch scale. The first length measuring scale can, for example, be glued or laminated onto the profile or engraved or embossed into the profile. The first length measuring scale can be formed, for example, by a tape measure connected to the profile. The first length measuring scale can in particular extend over most of the length of the profile.

The profile can be solid or designed as a hollow profile. The profile can be made partially or completely from a metal, for example aluminum, a metal alloy, or a composite material.

The holding unit can be partially or completely connected to the end section of the profile, for example in a materially bonded manner, in particular welded to the end section, and thereby fixed to the profile.

The adjustment unit is used to adjust the device according to the invention to the desired cutting and/or marking length. For this purpose, the adjustment unit can be positioned in different positions relative to the profile. Preferably, the adjustment unit is guided on the profile so that it can be moved continuously. To temporarily fix the setting unit in the respective setting position on the profile, the setting unit can have, for example, a clamping mechanism. Alternatively, the profile can have a clamping mechanism for temporarily fixing the adjustment unit to the profile.

The device according to the invention can be used for cutting panels in the form of plasterboard, tiles and the like. The respective plate cutting itself can be done directly by cutting using a cutting tool arranged on the device or indirectly only after the respective plate has been torn with the cutting tool.

According to an advantageous embodiment, at least one guide surface facing the holding unit and oriented transversely to the longitudinal extent of the profile is arranged on the setting unit for guiding the setting unit along an edge of a plate to be cut. The guide surface can be brought into flat contact with the edge of the plate, which can largely prevent the profile from moving out of its relative position perpendicular to the edge when the guide surface is moved along the edge of the plate, which affects the accuracy of the cutting and /or tearing would affect.

According to a further advantageous embodiment, at least one second length measuring scale is arranged on the profile, running along the longitudinal extent of the profile and circumferentially offset from the first length measuring scale with respect to the longitudinal extent of the profile, the second length measuring scale being arranged on the profile in such a way that an amount of main scale numbers of the second length measuring scale decreases starting from the holding unit in the direction of the setting unit and a cutting tool arranged on the holding unit is arranged at a second maximum dimension, which is coordinated with the second length measuring scale and which deviates from the first maximum dimension, of panels to be cut. This means that the same device can be used to cut two different sized standardized types of panels. The second length measuring scale is preferably divided linearly. The second length measuring scale can be metric or, for example, an inch scale. The second length measuring scale can, for example, be glued or laminated onto the profile or engraved or embossed into the profile. The second length measuring scale can be formed, for example, by a tape measure connected to the profile. The second length measuring scale can in particular extend over most of the length of the profile.

According to a further advantageous embodiment, at least one third length measuring scale is arranged on the profile, running along the longitudinal extent of the profile and circumferentially offset from the first length measuring scale with respect to the longitudinal extent of the profile, the third length measuring scale being arranged on the profile in such a way that an amount of main scale numbers of the third length measuring scale starting from the holding unit in the direction of the setting unit and a cutting tool arranged on the holding unit on one to the third length measuring scale coordinated zero point of the third length measuring scale is arranged. This means that the device can also be used according to a conventional folding rule in order to be able to cut a strip of a certain width from a plate. For example, the setting unit is set at 20 cm on the third length measuring scale if a 20 cm wide strip is to be cut from the plate. The third length measuring scale is preferably divided linearly. The third length measuring scale can be metric or, for example, an inch scale. The third length measuring scale can, for example, be glued or laminated onto the profile or engraved or embossed into the profile. The third length measuring scale can be formed, for example, by a tape measure connected to the profile. The third length measurement scale can extend in particular over most of the length of the profile.

According to a further advantageous embodiment, the profile has a polygonal cross-sectional area. For example, the profile can have a triangular or square cross-sectional area, in particular an equilateral cross-sectional area. The respective length measuring scale can be arranged on a respective flat outside of the profile. The polygonal cross-sectional area of the profile can also prevent the adjustment unit from rotating relative to the profile during movement along the plate with respect to the longitudinal extent of the profile, which would also affect the accuracy of the cutting and/or marking.

According to a further advantageous embodiment, the adjustment unit has at least one sleeve that at least partially encloses the profile radially on the outside with respect to its longitudinal extent and at least one clamping screw screwed into a radially extending threaded bore of the sleeve. The shape of a cross-sectional area of the sleeve can be adapted to a shape of a cross-sectional area of the profile in order to keep play between the sleeve and the profile low. By screwing the clamping screw into the threaded hole of the sleeve, the clamping screw comes into contact with the profile running through the sleeve, so that the profile can be clamped between the clamping screw and a section of the sleeve opposite the clamping screw. The clamping screw can be actuated by means of a tool or preferably by means of a handle connected to it.

According to a further advantageous embodiment, the adjustment unit has at least one handle connected to the clamping screw in a rotationally fixed manner. The handle is preferably designed so large that it forms a handle, a knob or the like. As a result, the device can be safely guided over the handle with one hand during a cutting and/or marking process, while the other hand can attack the holding unit or the cutting tool.

According to a further advantageous embodiment, the holding unit has at least one guide unit with an elongated recess for laterally guiding the cutting tool and at least one fastening element for fastening the cutting tool to the holding unit. As a result, transverse forces acting on the cutting tool during cutting and/or scribing can be absorbed by the guide unit, so that the cutting tool is not displaced laterally, which would impair the accuracy of the cutting and/or scribing. The guide unit can be designed in such a way that it can be placed flat on the plate and guided along it.

According to a further advantageous embodiment, the device has at least one cutting tool arranged on the holding unit in the form of a Stanley knife, the cutting tool being arranged on the holding unit so as to be pivotable between a cutting position and a rest position by means of the fastening element about a pivot axis arranged parallel to the longitudinal extent of the profile . The device can be designed in such a way that the Stanley knife automatically moves into its rest position due to the weight acting on it and can be manually pivoted out of this into the cutting position. The fastening element can, for example, have a threaded bolt guided through a section of the Stanley knife, which forms the pivot axis and onto which a nut can be screwed to secure the Stanley knife, for which purpose the threaded bolt can have an external thread at least on its free end section.

According to a further advantageous embodiment, the device has at least one cutting tool arranged on the holding unit in the form of a cutting wheel rotatably arranged on the holding unit. This configuration particularly favors the use of the device for cutting and/or marking tiles.

The invention will be explained below by way of example with reference to the attached figures using a preferred embodiment, with the features explained below both taken individually and in different combinations with one another can represent an advantageous and/or further developing aspect of the invention.

Detailed description of the characters

In the figures, identical or functionally identical components are provided with the same reference numbers. A repeated description of such components may be omitted in detail to avoid unnecessary repetition.

1 shows a schematic representation of an exemplary embodiment of a device 1 according to the invention for cutting panels, not shown.

The device 1 has a holding unit 2 for holding a cutting tool 3 in the form of a Stanley knife for marking and/or cutting the panels. For this purpose, the holding unit 3 has an L-shaped body 4, which has a first leg 5 and a guide unit 6 aligned perpendicular to the leg 5. The guide unit 6 has an elongated, one-sided open recess 7 for lateral guidance of the cutting tool 3.

In addition, the holding unit 2 has a fastening element 8 in the form of a threaded bolt for fastening the cutting tool 3 to the holding unit 2. The fastening element 8 is passed through the cutting tool 3. An adjusting nut 9 is screwed onto the fastening element 8, with which a position of the cutting tool 3 can be adjusted relative to the fastening element 8 or relative to the longitudinal extent of the fastening element 8. In addition, a self-locking nut 10 is screwed onto the fastening element 8, whereby the cutting tool is secured between the adjusting nut 9 and the self-locking nut 10. The fastening element 8 is also screwed into a threaded hole, not shown, on the leg 5, which should be indicated by the dashed line.

The device 1 also has a straight profile 11 with a polygonal cross-sectional area. In particular, the profile 11 is made as a square hollow profile made of a light metal or a light metal alloy. In 1 a top side 12 of the profile 11 is shown. The holding unit 2 is attached to the in by means of the leg 5 1 shown end of the profile 11 attached, in particular welded to this end.

On the top 12 of the hollow profile 11 there is a threaded hole 13 arranged, into which a threaded bolt, not shown, of a guide handle, not shown, can be screwed, over which the device 1 can be guided during a cutting and / or marking process. The cutting tool 3 is by means of the fastening element 8 about a pivot axis 14 arranged parallel to the longitudinal extent of the profile 11 between a cutting position, not shown, and the one in 1 shown rest position pivotably arranged on the holding unit 2.

Furthermore, the device 1 has an adjustment unit 15 which can be temporarily fixed to the profile 11 in various positions relative to the profile 11. Arranged on the setting unit 15 is a guide surface 16 facing the holding unit 2 and oriented transversely to the longitudinal extent of the profile 11 for guiding the setting unit 15 along an edge, not shown, of a plate to be cut, which is at least partially formed by two lateral guide flanges 25 of the setting unit 15 .

The adjustment unit 15 has a sleeve 17 which at least partially encloses the profile 11 radially on the outside with respect to its longitudinal extent and a screwed into a radially extending threaded bore 18 of the sleeve 17 6 clamp screw shown. In addition, the adjustment unit 15 has a non-rotatably connected to the clamping screw 6 handle shown. The further structure of the setting unit 15 results from 6 . The guide flanges 25 are arranged on opposite sections of the sleeve 17.

2 shows a schematic representation of the in 1 shown device 1 with a cutting tool 18 arranged thereon in the form of a rotatably arranged on the holding unit 2 cutting wheel. This can be done as an alternative to the cutting tool 1 be provided.

3 shows a schematic side view of the in 1 shown device 1. On the shown side 19 of the profile 11 of the device 1, the device 1 has a first length measuring scale 20 arranged on the profile 11 and running along the longitudinal extent of the profile 11. The first length measuring scale 20 is arranged on the profile 11 in such a way that an amount of main scale numbers (here: 60 (hidden by the sleeve 17), 70, 80, 90, 100, 110, 120), which are each given in cm, the first length measuring scale 20 decreases starting from the holding unit 2 in the direction of the setting unit 15. One arranged on the holding unit 2, for example in the 1 or. 2 The cutting tool shown is arranged on a first maximum dimension of 125 cm of panels to be cut, which is coordinated with the first length measuring scale 20 and indicated by a dashed line. The first maximum dimension of 125 cm forms a theoretical or imaginary end of the first length measuring scale 20, which is in 3 exactly in the middle above the one in the 1 and 2 shown recess 7 of the guide unit 6 of the holding unit 2 lies.

If, for example, a standardized plate with a first maximum dimension of 125 cm is to be cut to length to a dimension of 70 cm using the device 1, the setting unit 15, as in 3 shown, arranged on the profile 11 and temporarily fixed on the profile 11 in this relative position. The device 1 can then be placed on the plate so that the guide surface 16 of the adjusting unit 15 rests on an edge of the plate. Thereafter, the device 1 is pushed over the plate while the guide surface 16 of the adjusting unit 15 is continuously in contact with the edge of the plate and while the cutting tool has been brought into contact with the plate. In order to carry out this cutting and/or marking process using the device 1, a user of the device 1 does not have to do any calculations, but rather he can set the desired size of the plate directly on the device 1.

4 shows another schematic side view of the in 1 shown device 1. On the side 21 of the profile 11 shown is a running along the longitudinal extent of the profile 11 on the profile 11 and with respect to the longitudinal extent of the profile 11 circumferentially offset from that in 3 shown first length measuring scale arranged second length measuring scale 22 arranged. The second length measuring scale 22 is arranged on the profile 11 in such a way that an amount of main scale numbers (here: 140, 150, 160, 170, 180, 190), each given in cm, is assigned to the second length measuring scale 22 starting from the holding unit 2 in Direction of the setting unit 15 decreases. One arranged on the holding unit 2, for example in the 1 or. 2 The cutting tool shown is arranged on a second maximum dimension of 200 cm, which is coordinated with the second length measuring scale 22 and indicated by a dashed line and which deviates from the first maximum dimension of 125 cm, of panels to be cut. The second maximum dimension of 200 cm forms a theoretical or imaginary end of the second length measuring scale 22, which is in 4 exactly in the middle under the one in the 1 and 2 shown recess 7 of the guide unit 6 of the holding unit 2 lies.

If, for example, a standardized plate with a first maximum dimension of 200 cm is to be cut to length to a dimension of 140 cm using the device 1, the setting unit 15, as in 4 shown, arranged on the profile 11 and temporarily fixed on the profile 11 in this relative position. The device 1 can then be placed on the plate so that the guide surface 16 of the adjusting unit 15 rests on an edge of the plate. Thereafter, the device 1 is pushed over the plate while the guide surface 16 of the adjusting unit 15 is continuously in contact with the edge of the plate and while the cutting tool has been brought into contact with the plate. In order to carry out this cutting and/or marking process using the device 1, a user of the device 1 does not have to do any calculations, but rather he can set the desired size of the plate directly on the device 1.

5 shows a schematic bottom view of the in 1 shown device 1. On the shown underside 23 of the profile 11 is a running along the longitudinal extent of the profile 11 on the profile 11 and with respect to the longitudinal extent of the profile 11 circumferentially offset from that in 3 first length measuring scale shown and to that in 4 shown second length measuring scale arranged third length measuring scale 24 arranged. The third length measuring scale 24 is arranged on the profile 11 in such a way that an amount of main scale numbers (here: 10, 20, 30, 40, 50, 60, 70), each given in cm, of the third length measuring scale 24 starting from the holding unit 2 increases in the direction of the setting unit 15. One arranged on the holding unit 2, for example in the 1 or. 2 Cutting tool shown is arranged at a zero point of the third length measuring scale 24 which is coordinated with the third length measuring scale 24 and indicated by a dashed line. The zero point forms a theoretical or imaginary end of the third length measuring scale 24, which is in 5 is arranged exactly in the middle of the recess 7 of the guide unit 6 of the holding unit 2.

If, for example, a standardized plate with a maximum dimension of > 70 cm is to be cut to length to a dimension of 60 cm using the device 1, the setting unit 15, as in 5 shown, arranged on the profile 11 and temporarily fixed on the profile 11 in this relative position. The device 1 can then be placed on the plate so that the guide surface 16 of the adjusting unit 15 rests on an edge of the plate. Thereafter, the device 1 is pushed over the plate while the guide surface 16 of the adjusting unit 15 is continuously in contact with the edge of the plate and while the cutting tool has been brought into contact with the plate. In order to carry out this cutting and/or marking process using the device 1, a user of the device 1 does not have to do any calculations, but rather he can set the desired size of the plate directly on the device 1.

6 shows a schematic representation of the setting unit 15 in FIG 1 device shown. The adjustment unit 15 has the sleeve 17, on which the two guide flanges 25 are arranged laterally, which form the guide surface 16 of the adjustment unit 15. The two guide flanges 25 are dimensioned so large that they extend beyond the in 5 shown underside of the in the 1 until 5 shown profile, so that the protruding sections of the guide flanges 25 can be placed on the edge of a panel to be cut when the profile rests with its underside on the panel, i.e. on a large side of the panel.

Furthermore, in 6 the clamping screw 26 and the handle 27 of the adjusting unit 15, which is non-rotatably connected to the clamping screw 26 and designed as a handle, are shown, the clamping screw 26 being inserted into the in 1 shown, radially extending threaded hole of the sleeve 17 is screwed.
