Abstract: The invention relates to an enclosure, having openable and closeable lateral walls and roof surfaces, as well as a sliding door therefor, comprising frontwalls (14A, 14B), at least partially-openable and closeable lateral walls (16A, 16B) and roof surfaces (18A, 18B). According to said invention, at least one of the lateral walls is embodied as a curtain (20A, 20B) which can be wound up at the lower end thereof, which is kept ready by means of an end strip (22A, 22B), guided on both sides thereof, and which can be raised or lowered. When closed, the at least one guided end strip (22A, 22B) is embodied as a profile (P), at least partially forming roof surfaces and having a boundary area, oriented towards at least one lateral wall (16A, 16B), from which the curtain (20A, 20B) is hung in a substantially perpendicular manner.

Abstract: A sectional gate assembly to move a sectional gate between an open position and a closed position by an upper and lower closing element. The upper closing element is flexibly connected with the lower closing element, and both the upper and lower closing elements each have a first and a second opposite side and one or more guides which are arranged on each of the first and second opposite sides of the closing elements. The sectional gate assembly includes a first and a second single track guide rail. The first and second guide rails each have a vertical section and a horizontal section connected with a curved portion. One or more of the guides on the upper and lower closing elements are adapted to move within the guide rail. A weight-counterbalancer is included in the sectional gate assembly.
