TECHNICAL FIELD
The invention relates to a device for securing a camera to a carrier.
BACKGROUND OF THE INVENTION
Known from DE 10 2004 032 749 B3 is a device for fastening a rain sensor to a carrier, having a base part and a securing part that can be joined with the base part. The rain sensor is arranged between the base part and the securing part.
SUMMARY OF THE INVENTION
The invention is based on the problem of providing a device, relatively inexpensive to manufacture, that can be used to secure a camera to a carrier and to position the camera very easily and nevertheless precisely.
This problem is solved with a device for securing a camera to a carrier.
As a result of the fact that the inventive device exhibits a base part that is embodied in one piece from sheet metal as a punched and bent part, and has guide webs that extend in a longitudinal direction, the securing part, which has a web receptacle for each guide web, can be slipped onto the base part very easily. Through the interaction of the spring tongues and tongue receptacles, the securing part and thus a camera joined with the securing part can be positioned precisely in the securing position.
Although the invention has been described with a certain degree of particularity, it should be understood that those skilled in the art can make various changes to it without departing from the spirit or scope of the invention as hereinafter claimed.

DETAILED DESCRIPTION
FIG. 1 shows a perspective view of an embodiment of an inventive device for securing a camera 1 to a carrier that is not depicted in FIG. 1 and that is embodied in particular in the form of a window of a motor vehicle. The embodiment according to FIG. 1 has a base part 2 that is embodied in one piece from sheet metal as a punched and bent part. The base part 2 has a flat base plate 3 that is embodied at one end with edge tongues 4, 5 that extend in a longitudinal direction of the base part 2. The edge tongues 4, 5 extend from their joining ends in dovetail fashion with a distance between them that increases in the direction of the free ends, so that a V-shaped lens coverage recess is formed.
Furthermore, it can be seen from FIG. 1 that the embodiment of an inventive device depicted in FIG. 1 has a securing part 6 that is manufactured from plastic, is joined with the base part 2, and is set up to secure the camera 1 in a manner that is explained in more detail below. It can be recognized from FIG. 1 that the securing part 6 has a protective cover 7 that covers the lens coverage recess formed between the edge tongues 4, 5, extends beyond the base part 2 in a prolongation of the diverging inner edges of the edge tongues 4, 5, and decreases in its overall height in the direction pointing away from the camera 1. The protective cover 7 has lateral edge walls 8, 9 that also laterally delimit the lens coverage of a lens 10 of the camera 1, which lens is arranged in the region of the ends of the edge tongues 4, 5 that run towards each other.
Finally, FIG. 1 depicts that in this embodiment a sensor arrangement 11 is attached to the base part 2.
FIG. 2 shows a perspective view of an embodiment according to FIG. 1, looking towards the top that faces away from the carrier, which is not depicted in FIG. 2 as well. It can be seen from FIG. 2 that the base part 2 is embodied with a number of edge webs that extend parallel to the longitudinal direction, namely, on a longitudinal side with an inner edge web 12, with an outer edge web 13 that is offset laterally outward relative to the inner edge web 12 and is embodied with a continuous long edge web 14, all of which extend in the longitudinal direction of the base part 2 and are aligned at a right angle to the base plate 3. Placed in the transition region between the base plate 3 and the outer edge web 13 and the long edge web 14 are engagement recesses 15, 16, in which a system cover not depicted in FIG. 2 can latch and which can serve for gripping during transport of the base part 2.
Punched into the base plate 3 in the form of bridge-like raised areas are a number of guide webs 17, 18, 19 that extend in the longitudinal direction of the base part 2 in order to guide the securing part 6, which is equipped with web receptacles that are embodied complementarily to the guide webs 17, 18, 19, when it is slipped onto the base part 2. As can be seen from FIG. 2, a web receptacle is embodied in the form of a web receptacle socket 20 that extends outward from a face wall 21 of a receiving retainer 22 of the securing part 6.
Furthermore, the receiving retainer 22 has two side walls 23, 24 that are aligned essentially at a right angle to the face wall 21 and extend in the direction of the protective cover 7 on the side of the face wall 21 that faces away from the web receptacle socket 22. Made in each of the side walls 23, 24 is a round latching recess 25, 26, into which latching heads 27, 28, chamfered onto both sides of a central diagonal, of a camera housing 29 of the camera 1 can latch. As a result, the essentially L-shaped camera housing 29 is clasped by one leg of the receiving retainer 22 and mounted on the securing part 6 in pivoting fashion, whereby the other leg is latched with a latching web 30 formed on the protective cover 7.
Finally, it can be seen from FIG. 2 that one spring tongue 31, 32 each is formed on the inner edge web 12 on the top facing away from the base plate 3 as well as on the top of the long edge web 14 facing away for the base plate 3 in order to engage, in the securing position depicted in FIG. 2, with one of the tongue receptacles 33, 34 as soon as a limit stop lug 35 comes into contact with the face side, which faces away from the edge tongues 4, 5, of the inner edge web 12. As a result, both the securing part 6 and, accordingly, the camera 1, are securely and reliably positioned precisely.
FIG. 3 shows a perspective view of the base part 2 according to the embodiment of FIG. 1 and FIG. 2, looking towards the side that faces the securing part 6. It can be seen from FIG. 3 that the three guide webs 17, 18, 19 in this embodiment extend in the longitudinal direction of the base part 2 and are arranged offset transversely to this longitudinal direction in order to achieve the best possible guiding behavior. Furthermore, it can be seen from FIG. 3 that the spring tongues 31, 32 extend with a tongue segment 36 to the inside of the inner edge web 12 and the long edge web 14 respectively, and due to a cutout, are embodied in springy elastic fashion relative to the inner edge web 12 and the long edge web 14 respectively. Embodied on each of the free ends of the tongue segments 36 that face away from the free ends of the edge tongues 4, 5 is an engagement raised area 37, which is embodied by means of an angled chamfering and which extends in the direction of the base plate 3.
Finally, it should be noted that in order to increase the torsional stiffness of the base plate 3, a face web 38 is embodied at its edge side opposite the edge tongues 4, 5. Longitudinal recesses 39, 40 are embodied in the transition region between the inner edge web 12 and the long edge web 14 and the base plate 3 in order to create a mounting region for the sensor arrangement 11, for example.
FIG. 4 shows the securing part 6 according to the embodiment explained with the aid of FIG. 1 and FIG. 2, looking towards the side-that faces away from the base part 2. It can be seen from FIG. 4 that for securing the camera housing 29, the latching web 30 is embodied with a web lug 41, which extends in the direction of the receiving retainer 22 and with which the corresponding leg of the camera housing 29 can be latched.
Furthermore, it can be seen from FIG. 4 that placed on the side of the receiving retainer 22 that faces the protective cover 7 are tongue receptacles 33, 34 that are equipped on their side that faces away from the base part 2 with engagement recesses 44 that are embodied complimentarily to the engagement raised areas 37. Web receiving slots 47, 48, which engage with the guide webs 18, 19 that are arranged at the edges, are embodied as additional web receptacles between the tongue receptacles 33, 34 and the protective cover 7 with the joining webs 45, 46 that join the receiving retainer 22.
Although the invention has been described with a certain degree of particularity, it should be understood that those skilled in the art can make various changes to it without departing from the spirit or scope of the invention as hereinafter claimed.
