Abstract
A frameless housing composed of plates forming housing walls. Each plate is inwardly bent a number of times towards the inside of the housing along its side edges, possesses bevel-cut corners and the multiple angled or bent edges are each provided with a hollow channel-shaped section formed by bending, said section adjoining the associated plate side edge. A connection section bounds at the channel-shaped section and extends at an angle of approximately 45.degree. towards the inside of the plate. Upon interconnecting each two plates which abut one another at right angles at their connection sections a sealing member can be clampingly held between the channel-shaped sections which confront one another.
