Abstract
A Christmas-tree stand (2) features a foot-piece (4) with a connected holder (6) to which fastening components (14, 16, 18 and 20) are attached. In the example case, these components are swinging clamps which are pressed against the outer surface of the tree trunk by a clamping device (46). The pressure of the clamping device (46) is applied to the fastening components (14, 16, 18 and 20) via a steel cable (66), for example, which encircles them and is attached to the clamping device (46). The cable (66) moves the fastening components (14, 16, 18 and 20) toward the trunk with adjustable and evenly distributed force.
Claims16
Christmas-tree stand comprising:
- one foot-piece;
- a plurality of fastening components mounted on said foot-piece, said fastening components having a butt end and a pivotal end arranged symmetrically around a central axis, said components being swingable about a pivot axis proximal to said pivotal end, between an open and a fastening position in planes approximately intersecting at the central axis of symmetry, wherein the butt ends of the fastening components are pressable against a trunk of a tree;
- and
- a single clamping device acting on all of said fastening components simultaneously, said single clamping device including:
- a power transmission component mounted on said foot-piece for moving the fastening components into their fastening position with adjustable gripping force, wherein said fastening components are initially applicable to the trunk by said power transmission component basically without force and independently of each other, whereby said gripping force does not act on the trunk until all fastening components have made contact.
