Description

The present invention relates to a device for simultaneously measuring distances and generating a marking line, in particular an angular marking line.

It is known from the prior art and very popular with craftsmen to determine distances with a laser distance meter. These are usually handy devices that emit a laser beam, and the time it takes for the laser beam to hit an object and be reflected by it can be used to determine the distance of the object from the device. Such laser distance meters are used, among other things, in dry construction to measure distances.

In dry construction, it is also often necessary to cut larger panels, such as plasterboard, for example, have a format of 2.00 mx 1.25 m to smaller panels. Of course, high accuracy is essential here so that the cut panels are exactly the right size for the desired application. The cut panels often have to be rectangular in shape, i.e. the edges of the panels must be exactly at right angles to each other. However, absolute accuracy is not only required when cutting plasterboard, but also for any flat cuts, e.g. tiles, stones, OSB panels and chipboard.

In the prior art, for the precise cutting of such panels etc., markings are therefore first made on the panel to be cut or the planar element to be cut, along which markings are then cut. The markings are usually applied after measuring the distance with a ruler and with the help of a spirit level. A conventional laser distance meter is not used.

In order to be able to carry out the aforementioned work, you therefore need both a laser distance meter to determine the exact distance of an object and a folding rule and a spirit level to attach markings. Since this work in dry construction has to be carried out very frequently, it is also necessary to switch between these three auxiliary tools correspondingly frequently, which costs valuable time. Moreover, it is impractical for the worker to always carry all three auxiliary tools with him.

the CN 101799289A describes a laser measuring device that has a line laser arranged at a 90° angle to a distance measuring laser. The device also has two integrated spirit levels for a straight arrangement. This device is not suitable as an auxiliary tool for attaching markings at a 90° angle to a measured distance, as it only has two spirit levels, which do not offer the possibility of exactly aligning the device on an object. The device can therefore only be arranged with one long side approximately parallel to an edge of an object, which is why the marking emanating from the line laser can only run approximately at right angles to this edge. Since the device also has to be held by hand, especially when it is placed on objects that are not arranged horizontally, and it easily slips in the process, this makes it even more difficult to apply precise markings.

object of the invention

It is therefore the object of the present invention to provide an alternative device that overcomes the aforementioned disadvantages known from the prior art and is characterized in particular by a compact design and the fact that it can be used both for measuring distances and as an auxiliary tool when attaching markings is appropriate.

General Description of the Invention

The invention solves this problem with the features of the claims and in particular with a device for simultaneously measuring distances and generating a marking line, the device comprising a front side and a rear side, two opposite front sides and two opposite longitudinal sides, with one front side or a point laser is arranged on one long side of the device, and a line laser is arranged on a front side or on a long side of the device that is adjacent to the front side or long side on which the point laser is arranged, and wherein a contact surface in a Angle of 90 ° to the back of the device is attached to this.

The device according to the invention is in particular cuboid. The contact surface arranged on the underside of the device is in particular rectangular and extends in particular over a large part, for example over at least 60%, at least 70%, at least 80%, at least 90% of the length of the device and particularly preferably over the entire length of the device.

In the device according to the invention, the point laser is preferably arranged on an end face and the line laser is arranged on a longitudinal side adjoining this end face.

For the purposes of the invention, an arrangement of the point laser or line laser on a front side or a longitudinal side also includes an arrangement of the respective laser inside the (preferably cuboid) body of the device, with the light emitted by the respective laser being emitted on the front side or Long side emerges from the device, in particular at right angles to the respective front side or long side.

According to a preferred embodiment, an angle element, for example made of plastic, metal, steel or stainless steel, is arranged on the back of the device according to the invention, which has two surfaces arranged at right angles to one another or consists of them, one of the surfaces being the aforementioned contact surface, which in a Angle of 90 ° to the back of the device is attached to the device or the back. The angle element serves to place the device according to the invention flush against the edge of a flat object, for example a plate to be cut, so that a distance can be determined by the point laser along a longitudinal side or front side of the plate, while a laser light beam can be measured perpendicularly to this direction by the line laser. mark is created on the disk. In combination with the system described below, which, in addition to the device according to the invention, also includes two auxiliary tools for making markings, namely one for longitudinal markings and one for transverse markings, this has great practical value, particularly when cutting flat objects such as boards, wood and stones, etc., since the desired side length can be easily determined with the point laser, while the line laser generates a laser light marking perpendicular to this side, which can either be cut directly, or with the help of suitable drawing tools, for example A physical mark can be made with a ruler and pen, as well as a spirit level, which can then be used for cutting.

The device according to the invention can be obtained, for example, by converting a conventional commercially available laser distance measuring device. This device, which can be purchased commercially, has an integrated point laser whose light usually exits at one end of the device. In order to convert such a conventional laser distance measuring device into a device according to the invention, a line laser is mounted on a longitudinal side of the device that adjoins the end face on which the point laser is arranged or on which the light emitted by it exits. Furthermore, a bearing surface is mounted on the appliance perpendicular to the underside of the appliance, preferably in the form of an angle comprising two mutually perpendicular surfaces, one surface being the bearing surface and the other surface being substantially coextensive with the bottom of the appliance.

Since it is not necessary to remove the point laser from the device again, it is preferable for it to be cohesively connected to the device according to the invention, i.e. in particular to be cohesively connected to a front side or more preferably a longitudinal side of the device.

The angle element, on the other hand, is preferably detachably connected to the device. In particular, the angle element can be attached to the underside of the device with a screw connection which can be loosened without any problems, for example to replace the battery located in the body of the device.

The device according to the invention can preferably be arranged on a plate by placing the angle element with one of its two mutually perpendicular surfaces on a plate, in that the device rests with one of the two mutually perpendicular surfaces of the angular element on a front or longitudinal side of the plate, while the the other of the two surfaces of the angle element arranged at right angles to one another is arranged parallel to and rests on the front or rear side of the plate.

For the purposes of the invention, a panel is understood to be any flat object, which can be in particular a chipboard, an OSB panel or a gypsum plasterboard, but also, for example, a tile, a stone or another flat floor covering.

The invention also relates to a system for simultaneously measuring distances and generating a marking line, which comprises a device according to the invention and a first auxiliary tool for making transverse markings and a second auxiliary tool for making longitudinal markings, with both the first auxiliary tool and the second auxiliary tool each have two surfaces arranged at right angles to one another.

the 1 shows in the 1a) and 1b) schematically shows a device 1 according to the invention for simultaneously measuring distances and generating a marking line. The device 1 comprises a front side 2 and a rear side 3, two opposite end faces 4 and two opposite longitudinal sides 5, with a point laser 6 being arranged on one end face 4 and a line laser 7 being arranged on a longitudinal side 5 adjoining this end face 4. An angle element 9 is arranged on the rear side 3 of the device 1 . This consists of two surfaces arranged at right angles to one another, one of the surfaces running parallel to the rear side 3 of the device 1 and the other surface being arranged at an angle of 90° to the rear side 3 . This surface, which is arranged at an angle of 90° to the rear side 3, acts as a contact surface 8, by means of which the device 1 can be arranged flush on a plate, for example.

the 2 shows in the 2a) schematically a first auxiliary tool 10 for making transverse markings, for example on a panel to be cut. The first auxiliary tool 10 has two surfaces arranged at right angles to one another, one of the two surfaces comprising or consisting of a side surface of a wedge-shaped element 12 .

In the 2 B) is shown schematically how the interaction of the device 1 according to the invention with the first auxiliary tool 10 can simultaneously determine a distance and make a transverse marking. To do this, the first auxiliary tool 10 is placed in the top left-hand corner of an object to be cut or marked, for example a slab or a tile, so that one of the two mutually perpendicular surfaces of the first auxiliary tool 10 rests on the back of the object to be cut or marked and the other of the two mutually perpendicular surfaces is perpendicular to the front of the object to be cut or marked. In this way, the laser light point generated by the point laser 6 of the device 1 according to the invention when the device 1 is arranged as shown on the front side of the object to be cut or marked so that the contact surface 8 rests on a longitudinal side of the object to be cut or marked impinge on one of the two surfaces of the first auxiliary tool 10 arranged at right angles to one another. In this way, the exact distance from the device 1 to the front side of the object to be cut or marked, on which the first auxiliary tool 10 is arranged, can be determined. The dotted line in 2 B) is intended to indicate the course of the light beam generated by the point laser, which is not actually visible. However, the dotted line makes it clear at which point of the first auxiliary tool 10 the beam strikes and the actually visible laser point is generated.

On the other hand, the line laser 7 arranged on the longitudinal side 5 of the device generates a laser line which runs perpendicularly to the light beam generated by the point laser and parallel to the end face of the object to be cut or marked. In this way, with the help of the device 1 according to the invention and the first auxiliary tool 10, a distance can be measured and a transverse marking made at the same time. Although the laser line is shown as a dashed line, it is actually a solid line.

If the object to be cut or marked is, for example, a plasterboard to be cut, with a bit of practice it can be cut directly on the laser light marking generated by the line laser 7 at the desired distance. In the case of objects that are difficult to cut, such as tiles, a marking can first be made with a pen on the laser light marking generated by the line laser 7, on which cutting is then carried out.

the 3 shows in the 3a) schematically a second auxiliary tool 11 for making transverse markings, for example on a panel to be cut. The second auxiliary tool 11 has two surfaces arranged at right angles to one another, one of the two surfaces comprising or consisting of a side surface of a wedge-shaped element 13 .

In the 3b) is shown schematically how the interaction of the device 1 according to the invention with the second auxiliary tool 11 can simultaneously determine a distance and make a longitudinal marking. For this purpose, the second auxiliary tool 11 is positioned at the upper right corner of an object to be cut or marked, for example a slab or a tile, so that one of the two mutually perpendicular surfaces of the second auxiliary tool 11 rests on the back of the object to be cut or marked and the other of the two mutually perpendicular surfaces is perpendicular to the front of the object to be cut or marked. In this way, the laser light point generated by the point laser 6 of the device 1 according to the invention when the device 1 is arranged as shown on the front side of the object to be cut or marked so that the contact surface 8 rests on a front side of the object to be cut or marked impinge on one of the two mutually perpendicular surfaces of the second auxiliary tool 10. In this way, the distance between the device 1 and the long side of the object to be cut or marked, on which the second auxiliary tool 11 is arranged, can be determined exactly. The dotted line in 3b) is intended to indicate the course of the light beam generated by the point laser, which is not actually visible. However, the dotted line makes it clear at which point of the second auxiliary tool 11 the beam strikes and the actually visible laser point is generated.

On the other hand, the line laser 7 arranged on the long side 5 of the device generates a laser line (shown in dashed lines) which is perpendicular to the light beam generated by the point laser and parallel to the long side of the object to be cut or marked. In this way, with the help of the device 1 according to the invention and the second auxiliary tool 11, a distance can be measured and a longitudinal marking made at the same time.

The features of the invention disclosed in the above description, in the claims and in the figures can be essential both individually and in any combination for the implementation of the invention in its various embodiments.
