A stand for holding a rod-shaped unit, particularly a Christmas tree, comprises a foot part, a seating region for the tree trunk, said seating region being located on the foot part, several holding elements, which are supported around an axis of symmetry of the stand and which are pivotable against spring force out of an open position into a holding position, their pivoting planes intersecting approximately in the axis of symmetry, and at least one flexible force transfer element, particularly a steel cable, which can be actuated by means of a tensioning device and which can be loaded in tension and which engages around the holding elements and which, when tightened, causes the holding elements to pivot towards the axis of symmetry into the holding position. The holding elements comprise an upper dimensionally rigid holding region for transferring the tension and holding forces and a resilient element, which is fixed or is molded on below said holding region and by means of which the respective holding element is held in a receptacle, the holding element and its receptacle being designed such that the holding element is pivotable out of the open position into the holding position, that it is guided in its receptacle in this pivoting movement and that it simultaneously provides the spring force counteracting the pivoting movement.

The invention claimed is: 1. A stand for holding a rod-shaped unit, particularly a Christmas tree, said stand comprising a foot part, a seating region for the fixing end of the rod-shaped unit, said seating region being located on the foot part, with several holding elements, arranged in bearing blocks located around an axis of symmetry of the stand and which are each pivotable against spring force in a pivoting plane out of an open position into a holding position, said pivoting planes intersecting approximately in the axis of symmetry and with at least one flexible force transfer element, which can be loaded in tension and can be actuated by means of a tensioning device and which engages around the holding elements by being guided in a sliding manner above their pivot axes in guide openings of the holding elements and which when tightened causes the holding elements to pivot towards the axis of symmetry, where the holding elements include a resilient portion positioned below a dimensionally rigid holding region, each holding element being supported in a respective bearing block by the resilient portion, wherein the resilient portion is designed in such a way in the bearing block that the holding element is pivotable out of the open position into the holding position, and is guided in this pivoting movement in the bearing block while pivoting about a pivot axis and simultaneously providing a spring force counteracting the pivoting movement. 2. The stand according to claim 1, wherein the resilient portion is designed and supported in the bearing block in such a way that the holding element is pivotable about a moving pivot axis during its pivoting movement. 3. The stand according to claim 1, wherein in the resilient elements are designed as a V-shaped upwardly opening leaf spring, having one leg attached to the dimensionally rigid holding region. 4. The stand according to claim 1, wherein the resilient portion and the dimensionally rigid holding regions comprise a one piece structure. 5. The stand according to claim 1, wherein the resilient element is designed as a carrier of substantially constant bending stress. 6. The stand according to claim 1, wherein the holding elements are designed such that they can be locked into position in the respective bearing block by means of catch elements. 7. The stand according to claim 6, wherein the catch elements are located on the free end of the resilient portion. 8. The stand according to claim 6, wherein the catch elements are each designed as trailing cams on a free end of a free leg of a V-shaped resilient element (15). 9. The stand according to claim 1, further including guidance surfaces, for guiding the pivoting movement of the holding element, are provided on the holding elements and on the bearing blocks, said guidance surfaces corresponding to one another and being parallel to the pivoting plane of the respective holding element. 10. The stand according to claim 1, wherein the bearing blocks are molded on to the foot part of the stand or a surface-mounted part connected to the foot part, thus forming a single piece with said foot part or surface-mounted part. 11. The stand according to claim 1, wherein the holding elements comprise, above the dimensionally rigid holding regions, guidance surfaces inclined downwardly towards the axis of symmetry of the stand for facilitating the introduction of the rod-shaped unit. 12. The stand according to claim 1, wherein at least one force transfer element can be tightened by means of a foot operable tensioning device.
