DESCRIPTION:

BRIEF SUMMARY
The invention relates to a Christmas-tree stand as described in the preamble of claim 1.
With respect to Christmas-tree stands, it is generally a problem to securely fasten the Christmas-tree to be erected in such a way that the fastened Christmas-tree is essentially vertical, with the clamping procedure being as simple as possible and requiring little effort. A plurality of Christmas-tree stands are known which deal with the problem of making the fastening of a Christmas-tree in an essentially vertical position as efficient and simple as possible.
Christmas-tree stands are known in which the trunk end of the Christmas tree to be fixed and/or fastened can be fixed by a plurality of clamp screws radially arranged in the peripheral direction of the trunk. For this, the trunk end of the Christmas tree to be fastened is inserted in a sheath or pipe which is horizontally penetrated by clamp screws. By individually tightening the screws, the free ends of the screws may in part also penetrate into the material of the Christmas-tree, the Christmas-tree then being fixed in the sheath. The sheath is connected to the base or stand portion to ensure the necessary stability. The disadvantage with these known Christmas-tree stands, which are known in a plurality of variations and modifications, is the fact that a plurality of clamp screws, as a rule three or four of such clamp screws, has to be tightened individually in order to ensure a fastening as exact, i.e. as vertical as possible of the Christmas-tree trunk. Especially in the case of relatively large Christmas-tree and, thus, with large branches at the base, the individual tightening and, if necessary, again loosening of the clamp screws can only be accomplished in an awkward and complicated way.
A further category of Christmas-tree stands uses movable clamping arms or clamping bars which are forcibly engaged with a fixed support and thus fasten the trunk of the Christmas-tree to be fixed between each other. Examples of such Christmas-tree stands are known are publications DE-A 35 24 588 and DE-A 37 02 773. In these Christmas-tree stands, the trunk or the free trunk end to be fixed or fastened is fastened in the manner of a vise between a fixed or stationary support and a clamping arm or bar movable in relation thereto. The movement of the clamping arm and the application of the necessary clamping and retaining forces is caused by threaded spindles which have to be manipulated by hand. The plane of attack, i.e. the point on the free end of the Christmas-tree to be clamped between the fixed support and the movable clamping arm, is at a certain height and the lowest free end of the Christmas-tree trunk is fixed by a centering spike, which is vertically pointing and fixed to the Christmas-tree stand, so that, after fastening, the Christmas-tree trunk is fixed in the way of a three-point-support.
The disadvantage of Christmas-tree stands using a fixed support and a clamping arm movable in relation thereto, as described in DE-A 35 24 588 and DE-A 37 02 773, is the fact that tree trunks whose clamping region is not round or which considerably deviate from the round contour due to stumps of branches or the like can only with difficulty be fastened in a vertical position, if the lowest free trunk end has already been fixed by the centering spike. During the clamping of a tree trunk with such a non-circular or irregular contour by the movable clamping arm, which presses the trunk against the fixed support, said trunk with a non-circular or irregular contour can be pressed out of its vertical position, i.e. it may be fastened slantingly or askew during the clamping procedure.
In order to better meet the problem of tree trunks with non-circular or irregular contours, a Christmas-tree stand is known from DE-C 517 609 in which the Christmas-tree trunk can be fastened between clamping bars which are movable in relation to each other. For this, two separate clamping units are provided in the stand of DE-C 517 609, which are arranged horizontally one over the other at a distance
