Definitions

  • the invention relates to a device for positioning markings according to the preamble of claim 1.
  • Devices for positioning markings or for leveling markings, starting from a first reference marking are particularly common in the construction laser sector.
  • a typical task is to create two drill holes at a given distance at a given level. Assuming that a first mark corresponds to a later, first borehole, it is helpful for many users to know exactly where to start and drill the second borehole. After marking or drilling the first hole, this includes determining the distance and the position of the second or all further holes.
  • Construction lasers are available on the market and are available in different versions. There are, for example, rotating lasers that span a plane in space using a rotating, visible laser beam. Devices with manual leveling are available, for example via adjusting screws or vials, semi-automatic or fully automatic leveling. Due to this leveling, it is possible with the appropriate devices to generate an exactly horizontal or vertical alignment of the light signal.
  • line lasers that use a laser beam that clearly diverges in one plane, which, when it intersects the plane of a reference surface, projects a line on this reference surface, for example a wall, a floor or a ceiling, without the need to rotate the laser signal ,
  • Water trolleys with built-in laser function are known which, like the devices already described, can either be applied directly to a building site, or can be attached to rotatable auxiliary brackets and / or on tripods.
  • Line lasers are also known, which can be attached to a wall with the aid of a tool, such as a nail, a screw or a drill hole insert, and which can either be leveled manually using a built-in level or are self-leveling in the manner of a laser pendulum.
  • Such devices make it possible, for example, to project a laser beam in the previously leveled plane onto a wall in order to be able to position corresponding markings.
  • a laser beam leveling device is known from EP 1367364 ⁇ 2, which can be arranged with its housing on a reference surface, wherein a pendulum is arranged in the housing, which is pivotally coupled to the housing and carries at least one light source.
  • the pendulum which is subject to gravity, aligns the at least one light source horizontally, so that a light signal emitted by the light source generates an exactly horizontal line.
  • the device according to the invention for positioning marking hereinafter also called marking device for short, has a first device unit serving as a base part with means for arranging this first device unit at a predeterminable first position of a reference surface. Furthermore, this first device unit has optical signaling means for generating directional information.
  • a second device unit which serves as a running unit and can be positioned relative to the first device unit, and which has means which make it possible to determine the distance of this second device unit from the first device unit, and in particular from the predeterminable first position, it is possible to mark exactly in one predeterminable distance and to put on a predeterminable straight line.
  • a user starting from a first reference mark, for example a first borehole, to quickly and exactly make further markings, for example for further holes at a defined distance and in a defined horizontal or vertical position, without, for example, another person or another aid , such as a meter stick to help.
  • a first reference mark for example a first borehole
  • the means for determining the distance of the second device unit from the first device unit are designed as an optical measuring system. This can be done, for example, in the form of an optical distance measurement.
  • the distance measurement can take place, for example, according to the principle of a transit time measurement, a phase measurement, or else according to the triangulation principle.
  • the optical signal means of the first device unit which generate directional information for the second device unit, are used to determine the optical distance of the second device unit relative to the first device unit. This can be done, for example, by an under one
  • the second device unit advantageously has a light-sensitive sensor, for example a linear or two-dimensional one
  • Diode line which makes it possible to determine the relative distance of the second via the point of impact of the optical signal means emitted by the first device unit
  • Device unit from the first device unit and in particular from the first
  • the optical signaling means of the first device unit are advantageously visible from at least one laser, in particular a laser diode with emission
  • the optical signaling means of the first device unit are advantageously designed to be self-leveling. This is achieved, for example, in that the laser forming the optical signaling means is designed as a so-called pendulum laser in the housing of the first device unit and is therefore self-leveling in the gravitational field in such a way that the light emitted by the first device unit runs exactly horizontally.
  • the first device unit has means which make it possible to manually level the optical signal means for generating the directional information.
  • the first device unit can be provided, for example, with one or more vials, which allow the user to adjust the first device unit attached to the first reference surface.
  • the means for determining the distance of the second device unit relative to the first can be provided
  • the second device unit can have wheels, rollers or rolling elements, for example, which are designed as displacement transducers and detect the travel distance traveled by the second device unit.
  • the path for the second device unit can also be designed optomechanically, analogously, for example, to a scroll wheel in a computer mouse.
  • the second device unit can essentially be realized by a measuring tape in the first device unit, which can be pulled out of the first device unit along the direction specified by the optical signaling means and thus enables the desired distance and to determine the position of the second marking position.
  • a measuring tape or a measuring cord performing the same function can, for example, also be present in the second device unit and have means that allow this measuring tape or this measuring cord to be used with a
  • the device according to the invention has, in the first device unit and / or in the second device unit, display means which allow the distance value of the second device unit to be reproduced from the first device unit, and in particular from the first predetermined position on the reference surface.
  • display means which allow the distance value of the second device unit to be reproduced from the first device unit, and in particular from the first predetermined position on the reference surface.
  • Such a display should advantageously be embodied in the second device unit, since this is the active unit, ie the unit moved by the user, and is therefore directly visible to a user.
  • the device, in particular the second device unit advantageously has marking means which make it possible to mark a second position on the reference surface. This second position corresponds to the determined distance from the predeterminable first position along the direction specified by the first device unit by means of the optical signaling means.
  • Such a marking device can be designed, for example, as a stamp integrated in the device, in particular in the second device unit of the device, as an integrated ink spatter, which can, for example, mechanically, electronically, thermally, pneumatically or piezoceramically produce an ink blob on the reference surface.
  • a marking device can, for example, also be integrated through an integrated bore in the second device unit, which allows the exact position of the second marking to be marked or marked by means of a pen.
