BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention will also be explained in the following with respect to further advantages and features with reference to the enclosed drawing and to embodiments. The Figures of the drawing show in:

(2) FIG. 1 a schematic rear view of an optoelectronic measuring device having a preferred embodiment of a fastening system in accordance with the invention;

(3) FIG. 2 a schematic perspective view of an embodiment of a fastening section;

(4) FIG. 3 a perspective exploded view of a preferred embodiment of the fastening system in accordance with the invention; and

(5) FIG. 4 a perspective exploded view of a further preferred embodiment of the fastening system in accordance with the invention.

DETAILED DESCRIPTION

(6) FIG. 1 schematically shows a rear view of an optoelectronic measuring device M to be mounted at a stationary construction K having a preferred embodiment of a fastening system 1 in accordance with the invention. In the embodiment shown, the optoelectronic measuring device M represents a light grid that is to be mounted at a wall piece as the stationary construction K in accordance with the direction of the white arrow.

(7) The fastening system 1 comprises a fastening section 2 that is provided at a surface of a housing 3 of the optoelectronic measuring device M. In this respect, the fastening section 2 rises from the surface of the housing 3 and forms a platform 2a shown in more detail in FIG. 2. In accordance with the invention, the platform 2a has a groove 2b and a latch cutout 2c at at least one side located perpendicular to the surface of the housing 3.

(8) The fastening system 1 further comprises an adjustment adapter 4 that has a first element 4a for connection to the fastening section 2 and that is provided for the alignment of the measuring device M in the operating position. The first element 4a of the adjustment adapter has a tongue element 4b that, as shown in FIG. 3, is configured with shape matching to the groove 2b of the platform 2a of the fastening section 2. The first element 4a of the adjustment adapter 4 furthermore has a latching protrusion 4c that, likewise as shown in FIG. 3, is configured with shape matching to the latch cutout 3c of the platform 2a of the fastening section 2, whereby the fastening section 2 and the adjustment adapter 4 are latchingly connectable to one another without tools.

(9) In the shown embodiment in FIG. 1, the first element 4a of the adjustment adapter 4 makes possible a linear alignment of the optoelectronic measuring device M along its longitudinal axis.

(10) A schematic perspective view of an embodiment of the fastening section 2 is shown in FIG. 2, with the fastening section 2 in this embodiment being provided at an end cap 3a of the housing 3 of the optoelectronic measuring device M. The fastening section 2 shown in particular comprises four platforms 2a of which two respective ones 2b form a groove 2b and an intermediate space between the two platforms 2a forming a groove 2b forms the latch cutout 2c.

(11) The groove 2b serves to guide the adjustment adapter 4 during the placing onto the fastening section 2 so that the adjustment adapter 4 cannot cant with the fastening section 2. A placing together of the fastening system 1 can hereby be carried out simply.

(12) FIG. 3 shows a perspective exploded view of a preferred embodiment of the fastening system 1 in accordance with the invention in which the non-visible fastening section 2 is provided at the end cap 3a of the housing 3. From the perspective shown, the tongue elements 4b and the latching protrusions 4c of the first element 4a of the adjustment adapter 4 can be clearly recognized that ensure an exact guidance of the adjustment adapter 4 on the placing onto the fastening section 2 and a firm latching of the latching protrusions 4c into the latch cutouts 2c of the fastening section 2.

(13) The embodiment of the adjustment adapter 4 shown has a second element 4d that is preferably connected to the first element 4a at an angle, in particular of 90°, to one another. The second element 4d has a round spigot 4e that can be placed into a holder 5, whereby a rotation of the optoelectronic measuring device M about its longitudinal axis can be carried out in its operating position.

(14) The holder 5 can be mounted at a stationary construction K or at the wall piece so that the fastening system 1 is fixedly mounted together with the optoelectronic measuring device M or the light grid in the operating position of the optoelectronic measuring device M. In this respect, the round spigot 4e enables an exact alignment of the optoelectronic measuring device M to a zone to be detected.

(15) In accordance with FIG. 4, a perspective exploded view of a further preferred embodiment of the fastening system 1 in accordance with the invention is shown in which the non-visible fastening section 2 is likewise provided at the end cap 3a of the housing 3 of the optoelectronic measuring device M.

(16) Unlike the embodiment of the fastening system 1 shown in FIG. 3, the first element 4a of the adjustment adapter 4 can be placed on transversely to the longitudinal axis of the optoelectronic measuring device M. The second element 4d furthermore engages around the first element 4a such that the first element 4a is pivotably supported in the second element 4d.

(17) The first element 4a in this embodiment also has the tongue elements 4b by which the adjustment adapter 4 can be exactly placed onto the fastening section 2. The latching protrusion 4 is configured in the form of a tongue arm that engages into the corresponding latch cutout 2c of the fastening section 2 and fixes the first element 4a in the platform 2a of the fastening section 2.

(18) The second element 4d has guide grooves 4f at its inner side so that side edges 4g of the first element 4a can be guided in these guiding grooves 4f, whereby the first element 4a is pivotably supported with respect to the second element 4d. The optoelectronic measuring device M placed onto the first element 4a can hereby be pivoted with respect to the second element 4d so that the optoelectronic measuring device M can be aligned in its operating position when the fastening system 1 is mounted above the second element 4d at the stationary construction K.

(19) In this embodiment, the holder 5 can be dispensed with so that the total fastening system 1 is very narrow and compact, whereby the fastening system 1 together with the optoelectronic measuring device M hardly requires any space to be mounted in the operating position.
