  • Tree stands for stable anchoring of trees, especially Christmas and Christmas trees, are known in different designs. Simpler variants have a base plate and an associated receiving area, into which the lower trunk section of the tree to be anchored can be inserted and clamped using three or four toggle screws. To securely anchor the tree, the toggle screws must be tightened with considerable effort.

  • This relatively large holding force is a passive counter-holding force that prevents the tree from falling over.

  • the traction means need not necessarily be designed for very high tensile loads, since the clamping forces of the stand according to the invention are very much lower than in the known tree stands. Therefore, the traction means can also be a relatively simple plastic rope, which can consist, for example, of a plastic such as polyamide, nylon or the like.
  • a preferred embodiment of the invention provides that a fixing device for the lower trunk section is arranged on the bottom of the receiving area.

  • a metal insert with a plurality of tips or individual tips can be formed in each case on the free ends of the holding claws, which enables a tree to be anchored more stably with lower holding or tensioning forces.

  • the large wrap angle or the multiple wrap lead to a relatively low rope force, so that the tensioning device can be operated with significantly less effort. At the same time, however, this creates a large blocking force for the tree. Nevertheless, component stability can be reduced without any problems, which enables more cost-effective production.
  • the rope tensioning system also works without teeth. Instead of a stable steel cable, a lighter and cheaper plastic cable can also be used without any problems. Because of the translation, the tensioning device has a significantly better meterability. If a steel cable is used, it can have a very small diameter of less than 1 mm.
  • the clamping force essentially acts within the rope loop of the traction means, while in the previously known tree stands the entire claw system is pulled to one side of the tree stand, the stand being exposed to considerable forces and deformations.
  • the large wrap angle leads to friction effects between the
  • the result of the pull rope is the possibility of the single-shell or one-piece construction of the base and the inner part, and the possibility of forming the receiving area as a shell which is closed at the bottom and on all sides.
