Abstract: The invention refers to a door frame produced from sheet metal profiles of mainly U-shaped cross section, which profiles form the top and side pieces of the frame. The purpose is to provide a simple and inexpensive door frame, which can be attached to partition walls of different types independent of their design and which frame by some simple manipulations is mounted and finished to a complete unit with architrave fillets. These tasks have been solved in that the side pieces are laterally cross-cut, that the sheet metal profile is designed and arranged between side shanks (16) of the profile to receive the wall portions (17) bordering a door opening (18), and that the top piece (11) and the side pieces (12) of the frame (10) within the corner portions on one hand are arranged to overlap each other and on the other hand are provided with means (20,21) for mutual interconnection by means of hooking into each other.

Abstract: A stop end piece for closing particularly gutters, comprises a plate having a peripheral channel which is formed by the bent peripheral edge of the plate and a portion extending along said edge, which portion protrudes from the plane of the plate in the same direction as said peripheral edge. The peripheral edge has teeth which extend across the channel obliquely towards said portion and bear against or terminate at a small distance from the boundary surface of said portion, which faces said peripheral edge. The end of the gutter to be closed can be pressed into the channel, the teeth urging the inner side of the gutter wall into snug engagement with said boundary surface and simultaneously preventing withdrawal of the gutter end from the channel by their engagement in the outer side of the end of the gutter.
