Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
156 words
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.
Claim 2
Dependent Claim
156 words
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.
Claim 3
Dependent Claim
29 words
Christmas-tree stand in accordance with claim 1, wherein said fastening components are swingable on pivot axles which all lie in the same plane, perpendicular to the axis of symmetry.
Claim 4
Dependent Claim
28 words
Chistmas-tree stand in accordance with claim 1, wherein the power transmission component is applicable upon each fastening component in an area between the butt-ends and the pivot axle.
Claim 5
Dependent Claim
23 words
Christmas-tree stand in accordance with claim 1, wherein the fact that the power transmission component is made of a tensile and flexible material.
Claim 6
Dependent Claim
15 words
Christmas-tree stand in accordance with claim 1, wherein the flexible material is a steel cable.
Claim 7
Dependent Claim
16 words
Christmas-tree stand in accordance with claim 1, wherein the clamping device is a locking ratchet mechanism.
Claim 8
Dependent Claim
28 words
Christmas-tree stand in accordance with claim 1, wherein the power transmission component is a pressure line having a pressure cylinder attachable thereto which act upon the fastening components.
Claim 9
Dependent Claim
15 words
Christmas-tree stand in accordance with claim 7, wherein the clamping device is a pressure pump.
Claim 10
Dependent Claim
33 words
Christmas-tree stand in accordance with claim 7, wherein the said pressure cylinders are attached to the said fastening components in an area on the side of the pivot axles distal from the butt-ends.
Claim 11
Dependent Claim
38 words
Christmas-tree stand in accordance with claim 1, wherein the said butt-ends are of claw shape, the trunk of the tree being penetrable by said claws by the force exerted by the clamping device through the power transmission component.
Claim 12
Dependent Claim
40 words
Christmas-tree stand in accordance with claim 10, wherein the gripping force of the said claws is exerted on the trunk in such a way as to have a component of force in the direction of the foot-piece of the stand.
Claim 13
Dependent Claim
20 words
Christmas-tree stand in accordance with claim 1, wherein the said fastening components and the holder are formed of one piece.
Claim 14
Dependent Claim
22 words
Christmas-tree stand in accordance with claim 12, wherein the fastening components and the holder are manufactured out of a pilable elastic material.
Claim 15
Dependent Claim
14 words
Christmas-tree stand in accordance with claim 13, wherein the elastic material is spring steel.
Claim 16
Dependent Claim
21 words
Christmas-tree stand in accordance with claim 13, having a transitional area between the fastening components and the holder of increased elasticity.
Claim 17
Dependent Claim
24 words
Christmas-tree stand accordance with claim 15, wherein said increased elasticity is achieved by means of a deliberate weakening of the material in that area.
