[0001] The invention relates to a fastening system for fastening an optoelectronic measuring device, in particular a light barrier, in an operating position.

[0002] In today's era, more and more industrial applications are automated, so optoelectronic measuring devices, especially light barriers, are mainly used, for example, to detect areas or objects and transmit corresponding signals to the control system. For this purpose, it is usually necessary to install the optoelectronic measuring device in a specific operating position, where the optoelectronic measuring device is precisely aligned with the area to be detected or the object to be detected.

[0003] Known fastening systems are designed to be space-consuming and can therefore lead to so-called blind zones of the optoelectronic measuring device when the optoelectronic measuring device is mounted in its operating position. A blind zone is here understood to mean an area which cannot be detected by the optoelectronic measuring device due to the known fastening systems.

[0004] Furthermore, the known fastening systems may result in the optoelectronic measuring device being spaced a great distance from the fixed structure to which the known fastening system is fastened, so that in certain applications the optoelectronic measuring device with the associated fastening system cannot be used due to lack of space.

[0005] Furthermore, in order to mount the known fastening systems on the optoelectronic measuring device and to place them in the operating position, it is necessary to have the necessary tools at hand, which makes the mounting of the known fastening systems and optoelectronic measuring devices difficult or even impossible in certain applications.

[0006] The object of the present invention is to provide a fastening system for fastening an optoelectronic measuring device, in particular a light barrier, in an operating position, by means of which fastening system a simple mounting and alignment of the measuring device can be achieved.

[0008] Advantageously, the fastening part is arranged on the end cap or the rear wall of the housing, which makes the structure of the entire fastening system very compact. The technical advantage obtained thereby is that when the optoelectronic measuring device is mounted in the operating position by means of the fastening system, a blind area of ​​the optoelectronic measuring device can be avoided.

[0009] According to a preferred embodiment, the fastening part comprises four platforms, wherein every two platforms form a groove, and the middle area between the two platforms forming the groove forms a stop recess. The fastening part can be easily manufactured by injection molding the end cap or the housing of the optoelectronic measuring device. In addition, by engaging the stop protrusion into the stop recess, the fastening system can also be mounted on the optoelectronic measuring device without using tools.

[0010] Furthermore, according to a preferred embodiment, the adjustment adapter has a second element.

[0011] In particular, the second element is advantageously connected to the first element at an angle, in particular at an angle of 90°. Furthermore, the second element advantageously has a round plug that can be inserted into the holder, whereby the optoelectronic measuring device can be rotated. Advantageously, the holder can be mounted on a fixed structure, for example on a wall or a bracket. Since the fastening device can be mounted on the fixed structure via the second element or the holder, different mounting possibilities are provided for the optoelectronic measuring device.

[0012] Furthermore, in particular, the second element surrounds the first element so that the first element is pivotably mounted in the second element. As a result, the fastening system enables a pivoting of the optoelectronic measuring device despite a more compact construction. Advantageously, the second element can be mounted on a fixed structure or can be inserted into a holder which can be mounted on the fixed structure. As a result, further different mounting possibilities are provided for the optoelectronic measuring device. BRIEF DESCRIPTION OF THE DRAWINGS
