Pendulum laser device

State of the art

The invention relates to a pendulum laser device comprising: a housing having at least one outer surface; a pendulum arrangement arranged in the housing and a laser unit attached to the pendulum arrangement, wherein the laser unit is freely self-alignable by means of the pendulum arrangement independently of a housing orientation on the solder and is designed to generate a laser beam oriented perpendicular to the solder.

In order to carry out leveling and / or marking tasks in the field of craftsmanship, for example interior finishing, laser products have been used for some time which, depending on the application, produce laser markings in order to realize a reference independent of the orientation of floors, ceilings or walls. A distinction is made between so-called rotary lasers, in which a laser signal is fanned out by rotation of the light source or a beam deflecting device in a plane to be adjusted and thus defines a reference surface and so-called line lasers, which allow projection of the laser signal to a reference surface that a predetermined direction visible will and can be respected. For example, EP 0 785 412 A2 discloses a laser leveling device with an elongated housing and dragonflies, which can be used as a laser spirit level with the housing in one levels and sends a laser beam for marking purposes. From DE 295 11 266 Ul a marking laser is known in which a laser unit is not movable, that is permanently installed in a housing and wherein the housing forms an automatically perpendicular aligning pendulum. From DE 29511266 a marking laser is known in which a laser unit is not movable, that is fixedly mounted in a housing and wherein the housing forms an automatically perpendicular aligning pendulum. From DE 29716316 Ul a pendulum laser for leveling and / or attaching markings on walls is known which has a housing with a suspension device, wherein the housing has an opening for a laser beam of a freely suspended from a pendulum axis laser beam generator.

An aforementioned known per se Pendellaser- device is used for leveling and / or marking using the laser beam generated by the laser unit on objects, for example, to display horizontal lines on surfaces, such a line is independent of a housing orientation of the pendulum laser device perpendicular to the Lot is. Such a line is independent of the orientation of the outer contact surface of the pendulum laser device and the usable for leveling and / or marking line is generated by the laser unit, which is free self-aligning as such independently of a housing orientation on the solder. The pendulum mode described forms the basic function of an aforementioned self-leveling or marking pendulum laser device.

It is known to push a mounted on a pendulum assembly laser unit in pendulum mode to the side and there determine. This additional function serves to set the laser unit for protection and transportation. The laser unit is thereby detected at an inappropriate for leveling and / or marking position - in the worst case, a laser beam in this position can not penetrate out of the housing to the outside.

It is desirable to make a pendulum laser device versatile usable.

The invention is based on the consideration that in practice there are many applications requiring leveling and / or marking by lines relative to an existing reference surface. For this purpose, a corresponding marking line regularly does not necessarily have to be oriented perpendicular to a perpendicular. The invention has recognized that it is possible for such use, in addition to the pendulum mode of the pendulum laser device, to provide another mode - a set mode - in which, according to the concept of the invention, the laser unit is aligned in a geometrically predefined manner relative to the contact surface by a fixing means can be fixed - according to the concept of the invention for generating a relative to the contact surface fixed laser beam at a fixing position. As a result, according to the concept of the invention, the laser beam is fixed at a fixing position suitable for leveling and / or marking relative to the contact surface.

As a result, the above-mentioned cases of marking necessity relative to a reference surface which frequently occur in practice, in addition to those cases where horizontal marking is required independently of the reference surface, can equally be handled by a pendulum laser device.

Advantageous developments of the invention can be found in the dependent claims and give in particular advantageous ways to realize the above-described concept within the scope of the task, as well as with regard to further advantages. In particular, the laser unit for generating a fixed at a predefined angle to the contact surface, in particular perpendicular and / or parallel to the outer plant surface laser beam can be fixed - in principle, a non-right angle is possible. The Pendellaser- device can thus outside of the pendulum mode as an angle, in particular parallel and / or perpendicular, to a reference, for example, a surface of an object, using the laser beam for marking, if necessary. Additional leveling in the event that the angle relative to the Außenanlageflache coincides with a measure relative to the Lot, to serve on other objects. Preferably, the laser unit is formed in the form of a line laser and / or a cross-line laser.

Preferably, the fixing means acts directly on the pendulum assembly and / or the laser unit. Particularly suitable is an associated with the laser unit and / or the pendulum assembly adjustment has proven, for example, a "male" part. In a particularly preferred embodiment, it has been found to be advantageous for the fixing means to comprise a male part and a female part associated with the male part It has been found that a male part and a female part The said parts can preferably be guided relative to each other for fixing the laser unit to one another, that is, during the transition from the pendulum mode to the fixing mode of the pendulum laser device, the male part and the female part are guided towards one another and fixed to one another. Further, alternatively or additionally, most preferably, the male part and the female part led apart to transfer the pendulum laser device from the set mode to the pendulum mode, that is, to allow a free self-alignment of the laser unit.

It has been shown that it is particularly advantageous, especially for constructive reasons, to arrange the male part on the laser unit and to arrange the female part on the housing. The female part is preferably arranged on an inner surface of a wall of the housing which has the outer contact surface. The male part is particularly easy to attach to a housing of the laser unit.

Basically, there are different ways to make the male part and the female parts to each other feasible. In a first variant of this development, it has proven to be particularly advantageous to make the male part, in particular the laser unit, and / or the female part, adjustable in height and / or apart from one another. In a further preferred, second variant of this development, it has proved to be advantageous to make the male part, in particular the laser unit, and / or the female part to be mutually and / or apart laterally adjustable.

The above-mentioned arrangement of the male part on the laser unit and the female part on the housing and the different types of movement of the male part and / or the female part can also vary and combine with each other. For example, the male part can also be arranged on the housing and the female parts on the laser unit. Next, only the male parts and / or only the female part movable, that is in particular height adjustable or laterally adjustable to be. The type of variation and / or combination of the above developments can be made depending on the preferred use of the pendulum laser device and the structural requirements in the housing.

In principle, various embodiments of a female part and / or a male part are possible. It has proven to be particularly preferred that the female part is formed in the form of a receptacle and / or the male part is formed in the form of a lug. A border of the receptacle and / or heel can be straight or curved perform in all cases with or without a waist. Preferably, the female part is formed in the form of a funnel-like receptacle and / or the male part is formed in the form of a tapered neck. This development has proven to be particularly advantageous because it acts practically self-adjusting when the male part and female part to each other.

The laser unit preferably has a line laser and / or a wreath line laser and / or a rotation laser.
