Protective housing for optical appliances

摘要

A protective housing for optical appliances, particularly for monitoring video cameras, has a tubular housing casing (1) which can be displaced telescopically relative to an appliance mounting (2) which can be mounted in a fixed position. The housing casing (1) and the appliance mounting (2) are connected to one another via a sliding guide element (4) which, at the end of the displacement movement, forms a pivoting bearing (S-S) for the housing casing (1) to pivot downwards about the end of the appliance mounting (2). In order to simplify the assembly (installation) and to avoid the viewing angle being masked during assembly and adjustment, both the housing casing (1) and the appliance mounting (2) are provided with guide grooves (11, 15), which are in each case arranged in pairs, and the sliding guide element (4) is displaceably guided by means of first and second projections (18, 19), relative to both the housing casing (1) and to the appliance mounting (2), in their guide grooves (11, 15). At the same time, at least one of the projections (18, 19) of the sliding guide element (4) forms the pivoting bearing (S-S) between the housing casing (1) and the appliance mounting (2). The sliding guide element can be designed either as a moulding or as a wire bracket. <IMAGE>
