Description

A screw joint arrangement and a device comprising at least one screw joint arrangement The present invention relates to a screw joint configuration and an apparatus comprising at least one such screw joint configuration. More specifically, the present invention relates to a screw joint configuration for fixing a first member and a second member to each other. Screw joint configurations are commonly used to fasten two members together using screws. A common problem associated with screw joint configurations is the risk of the screws coming loose during handling. It is known that a screw joint configuration having a retainer function is provided to secure a screw to one of the members. One such solution is disclosed in DE4243097A1. A specific type of screw joint configuration may allow the relative position of two members to be adjusted by loosening and then retightening the screw joint configuration. A problem associated with this type of screw joint configuration is the risk of the screw coming loose during the adjustment process, which can be cumbersome, particularly when the screw joint is used in applications located in hard-to-reach places. An example of this could be a surveillance camera mounted on an indoor ceiling equipped with such a screw joint configuration. Therefore, there is a need for an improved screw joint configuration that enables relative positional adjustment of two members while providing a retention function for the screw. In addition to the matters set forth above, further objects, features, and advantages of the present invention may be more clearly understood through the following exemplary and non-limiting detailed description of preferred embodiments of the present invention with reference to the accompanying drawings, wherein the same reference numerals denote similar elements, and in the drawings, FIG. 1a is a cross-sectional view of a first member of a screw joint configuration according to a first embodiment.
