Abstract: An adjustable foot of a piece of furniture or support, having an adjusting arrangement formed from an internal adjusting part and a sleeve element displaceably mounted on the internal adjusting part. With a simple structure, a multiple variability of the foot of a piece of furniture or support is possible when the sleeve element is configured as a connector element, the outer surface of which is adapted to the internal diameter of an external profile for insertion into the external profile and has an abutment, on which the external profile is supported in the inserted position.

Abstract: An adjustable furniture device having at least one adjustable longitudinal support element including a female section and a male section in telescoping engagement, with positionally-adjustable devices interposed between the male and female members to permit longitudinal adjustment of the support element, and thereby adjustment, for example, of height.

Abstract: A sleeve for flowerpots which is folded in zig-zag manner along convex outer and convex inner fold lines at least over a major part of a height thereof. Concave connecting fold lines are provided at a distance from a marginal edge, with the concave connecting fold lines connecting adjacent outer and inner main fold lines. Between the connecting fold lines and the marginal edge, the arrangement and folding direction of fold lines continuing the main fold lines are interchanged as compared with the main fold lines of the sleeve material.
