Definitions

  • the invention relates to a tree stand, consisting of a housing and clamping means arranged therein for a tree trunk.
  • a tree stand (DE-U 7 533 510) which consists of a threaded lower housing part and a sliding cone which can be screwed therein.
  • radially displaceable clamping claws are arranged in the lower housing part, which have a bevel on their outward-pointing upper edge, on which the sliding cone acts.
  • the sliding cone By turning the sliding cone, the clamps are moved towards the center of the lower part of the housing until the tree trunk is firmly clamped.
  • This tree stand can only cover a small range of tree trunk diameters, since the slope at the rear end of the clamps must not exceed a certain angle, since otherwise the clamps can no longer be moved horizontally.
  • the invention is therefore based on the object of providing a tree stand with which the largest possible trunk diameter range can be covered.
  • the inner wall of the housing has a plurality of spirally curved surfaces which are arranged in the housing in such a way that one end is closer to the center of the housing than the other, in that a guide part with a plurality of guide curves is arranged in the center of the housing base is, the curvature of the curved surface corresponds to that between the guide part and curved surface, for example Clamping means designed as tensioning rollers are arranged for the tree trunk, and that actuating elements which are rotatable relative to the housing are provided for the tensioning means.
  • a cover that can be rotated relative to the housing is provided, which has the actuating elements for the clamping means on the inside.
  • the guide curves of the guide part have end stops for the tensioning rollers, which ensure that the tensioning rollers only move in an area assigned to them in the housing, which is approximately 120 degrees when three tensioning rollers are used.
  • Each actuating element is designed in the manner of a cap, which grips the tensioning roller, so that play-free guidance of the tensioning rollers through the cover in the housing is ensured.
  • This tree stand design covers a tree diameter range of 50 to approximately 100 mm.
  • the curved surfaces on the inner wall of the housing and, corresponding to this, the tensioning rollers have a toothing, as a result of which a positive connection is ensured, which brings about a secure clamping of the tree trunk in the tree stand.
  • Guide grooves for guiding the cover are provided on the top of the housing, the cover having guide pins which protrude into the guide grooves.
  • the lid can be fixed on the housing, for example by means of a tensioning lever, so that the tree trunk cannot come loose from the tree stand.
  • the tensioning rollers have sliding shoes on their lower side in order to thereby facilitate the sliding of the tensioning rollers on the housing base.
  • the housing is designated 1.
  • Three spirally curved surfaces 2a, 2b and 2c are arranged on the housing inner wall 1a, so that one end 19 of the surface lies closer to the center of the housing than the other end 20.
  • These surfaces 2a, 2b, 2c each have a toothing 3 which interacts with the toothing 5 of the tensioning rollers 4a, 4b, 4c.
  • a guide part 6 is arranged in a fixed manner on the housing base 17 and has the guide curves 7a, 7b, 7c, the curvature of which is designed in accordance with the curved surface 2a, 2b, 2c.
  • the distance between the guide curves 7a, 7b, 7c and the spirally curved surfaces 2a, 2b, 2c corresponds in each case to the lower diameter 18 of the tensioning rollers 4a, 4b, 4c.
  • Each guide curve 7a, 7b, 7c is formed at its end so that it forms a stop 8a, 8b, 8c. In this position of the tensioning rollers, the distance to the center of the housing is the smallest (Fig. 2).
  • tensioning rollers are on the shoulder 9, then they are at the greatest distance from the center of the housing (Fig. 1).
  • Guide grooves 10 are arranged on the upper housing part 23, into which the guide pins 11 (FIG. 3) of the cover 12 extend.
  • the cover is held by a tension pin 21 which is also guided in a guide groove and is connected via an axis 13 to a tensioning lever 14 which is located in a recess 22 in the cover 12 which is adapted to the upper housing part (FIG. 4).
  • a tensioning lever 14 which is located in a recess 22 in the cover 12 which is adapted to the upper housing part (FIG. 4).
  • the tensioning rollers 4a, 4b, 4c each have sliding shoes 15a, 15b, 15c on their underside, which facilitates the sliding of the tensioning rollers on the housing base 17 (FIG. 3).
  • Fig. 3 and Fig. 5 it can be seen that the tensioning rollers 4a, 4b, 4c by actuating elements 16a, 16b, 16c arranged in the cover 12, which are designed in the manner of a semicircular cap, are detected, whereby when the cover rotates on the Upper part of the housing causes the movement of the tensioning rollers along the curved surfaces 2a, 2b, 2c in the direction of arrow 25.
  • the tensioning rollers in particular the sliding shoes 15a, 15b, 15c, move in the path which is formed on the housing base 17 by the spiral surface 2a, 2b, 2c and the guide curves 7a, 7b, 7c. During this movement, the distance between the tensioning rollers and the center of the housing decreases continuously, so that the tree trunk can be clamped.
  • recessed handles 24 are provided in the lid.
  • the lid 12 has an opening 25 in the center so that the tree trunk can be used.
