Description

The invention relates to a stand for anchoring a rod-shaped object, in particular for anchoring a tree, with a base region and with an integrated receiving region arranged therein for a lower trunk portion of a tree or other rod-shaped body to be anchored, for example a flagpole or the like.

Tree stands for the stable anchoring of trees, especially of Christmas or Christmas trees, are known in different designs. Simpler variants have a bottom plate and an associated receiving area, in which the lower trunk portion of the tree to be anchored inserted and clamped by means of three or four thumbscrews. For secure anchoring of the tree, the toggle screws must be tightened with considerable force.

In addition, tree stands are known, which are provided with a pulling device, by means of which a series of pivotable holding elements can be pressed against the stem portion of the tree, so that it is anchored stable. These traction devices typically include a cocking lever with a ratcheting and locking device that can normally be operated by foot power. The locking device typically has a locking device that can be opened for quick release of the tree.

Christmas tree stand with cable and pivotally mounted pivoting levers, in which a Christmas tree is held with claws, which are pulled together with a rope, are, for example, from the DE 39 32 473 A1 , from the DE 297 07 643 U1 , from the US 6419202 B1 as well as from the DE 201 05 005 U1 known.

A pivotable retaining element with a return spring, which is part of a Christmas tree stand, is further from the DE 102 02 891 A1 known. The DE 203 09 947 U1 further relates to a tensioning device in the manner of a ratchet for tensioning a rope. The clamping device is also part of a Christmas tree stand.

A disadvantage of many known systems is the relatively complex production of the tree stand and the lack of leakage safety of water.

An object of the present invention is to provide a tree stand which has a simple and inexpensive to produce design and also allows easy handling.

This object of the invention is achieved with the subject matter of the independent claim. Features of advantageous developments of the invention will become apparent from the dependent claims.

An inventive stand for the stable anchoring of a rod-shaped object, in particular a tree, Christmas tree o. The like., Includes a base portion and a receiving portion arranged therein for a lower portion of the object to be anchored. The stand has at least three holding elements which are arranged concentrically around the receiving region and are pivotable about a horizontal axis in a plane perpendicular to the longitudinal axis of the rod-shaped article or tree, preferably by means of a single traction element guided in each case in the holding elements is operatively connected, are clamped against the circumference of the rod-shaped object or the trunk portion of the tree. One end of the traction means can be clamped in the clamping device, while the other end can be fixed or countered in one of the holding elements or in the tree stand. The traction means is mounted in the form of a rope loop in the holding elements. Such a stand has the advantage of a secure and stable anchoring possibility of a tree to be anchored, with only very low clamping forces are necessary. The relatively high self-locking force of the tree almost around its entire circumference or possibly also several times looping traction means within the guides of the holding elements also provides over the known tree stands for a significant improvement in the holding properties of the tree stand according to the invention. In the form of a lasso loop or rope loop (or in the form of a tie knot) or in several loops in the Guided holding elements and these pulling together pulling means is subject to relatively low tensile forces, but can exert a relatively large holding force on the holding elements. This relatively large holding force is a passive holding force that prevents the tree from falling over. This counter-holding force forms a blocking force against displacement, pushing away or joint displacement of the retaining claws. The arrangement of the traction means and the holding elements causes very high blocking holding forces to be achieved by means of a relatively small required clamping force.

In the case of a traction device that is looped around the tree several times, there is the additional advantage that due to the transmission ratio, the tensioning forces become very small, so that the tree can also be easily fastened and anchored by children. In a multiple times wrapped around the tree traction means this can each extend in the same guides of the holding elements. Alternatively, in each case a plurality of guides may be provided, in each of which a portion of the traction means is guided.

By means of a test set-up the superiority of this clamping system could be checked and proven. With the system according to the invention, for example, a tree of three meters in height can be easily anchored by means of a steel cable of 0.4 millimeter diameter and secured against falling over. In contrast, in known tree stands steel cables of about 3 mm thickness are necessary, which have the disadvantage of a very low flexibility, so that the cable guide would be relatively stiff in the holding elements.

For secure anchoring of a tree at least three pivotable retaining elements are necessary. Optionally, four or five holding elements may be provided, which are expediently arranged uniformly over the circumference of the receiving area. The traction means is displaceably guided in each case in receptacles of the at least three holding elements. Preferably, the traction means is guided in each case in a receptacle of the at least three holding elements, which is arranged between a pivot axis and an upper free end of the holding element. In this way, favorable leverage conditions are given, which can achieve a good clamping effect for the tree to be anchored with relatively little force, without the traction means would deflect inadmissible, which due to Leadership properties of ropes would lead to relatively high friction losses and thus to an increase in the necessary clamping force.

According to a variant of the invention, a free end of the traction means is countered with a stop against a guide of the holding elements. This holding element is preferably the same, in which the traction means is passed from the holding elements to the clamping device. For this purpose, the holding element, in which the free end of the traction means is countered, a further guide for the traction means. According to an alternative embodiment of the invention, the free end of the traction means is countered in the tree stand itself, for example. In the base area. In principle, the same effects and effects can be achieved as with a traction mechanism end countered in a holding element.

The guides in the at least three holding elements are each arranged horizontally. The further guide for the traction means can be arranged horizontally or arranged slightly inclined, so that a favorable deflection of the traction means between the clamping device and the holding element is made possible. Optionally, the traction means may also have a curved or curved course.

Between the tensioning device and the receiving area, a further guide for the traction means can be provided, which ensures a favorable deflection and the traction means.

The traction means preferably runs, in this order, between the tensioning device, the guide in the receiving area, the further guide in the first holding element and the horizontal guide in the further holding elements. As a pulling means in particular a rope, such as a steel wire rope or a plastic rope o. The like. In question. The traction means need not necessarily be designed for very high tensile loads, since the clamping forces of the stator according to the invention are much lower than in the known tree stands. Therefore, the traction means may also be a relatively simple plastic rope, for example, from a plastic such as polyamide, nylon o. The like. May exist.

A preferred embodiment of the invention provides that a fixing device for the lower trunk section is arranged at the bottom of the receiving area. This fixing device, which with a lower end face of the trunk portion can interact, for example, be a centering or holding mandrel. Optionally, the fixing device may also be a ring, a receiving trough or another suitable device which secures the lower end face of the tree to be anchored against slipping.

The holding elements are preferably designed in each case as pivotable holding claws or the like. The holding elements may each be associated with a spring tensioning device, which pivots the holding elements with unloaded traction means from the tree. The spring tensioning device can in each case ensure that when the tensioning device is released the tree is released. At the free ends of the retaining claws in each case a metal insert with a plurality of tips or individual tips may be formed, whereby a more stable anchoring of a tree with lower holding or clamping forces is possible.

The receiving area may in particular be designed as a cup-shaped container, which is closed laterally and towards the bottom, so that, for example, a water filling up to an upper edge of the receiving area is possible without the water running out laterally.

The invention provides for a one-piece design of the pot-like receiving area for the tree with the base area, which can be produced, for example, by means of an injection molding process. Within the base region stiffening ribs can be provided, which allow a very light and at the same time stable embodiment. Even with relatively small wall thicknesses of the plastic stand or pedestal area that can be produced, a high level of stability and flexural rigidity is ensured.

The guide in the receiving area for the traction means is preferably arranged on the upper edge of the receiving area. The pivot bearings for the retaining elements are preferably arranged in each case at the upper peripheral edges of the receiving area.

The holding elements, the cup-shaped container of the receiving area and an outer housing shell or the base area can optionally be made of plastic or metal. Optionally, the container and the outer Housing shell and / or the base area also be made as glass, ceramic, clay, wood or concrete.

The base area may optionally be provided with one or more ballast pieces, which improve the stability of the tree stand. If necessary, these ballast pieces can be integrated into the base area, which can be done, for example, by means of the injection molding process. However, they can also be retrofitted, for example by screwing or gluing from below. One or more ballast devices can be arranged between the base, the housing shell and the receptacle, for example in the form of concrete weights or the like. It is also possible to pour ribs with different casting compounds.

Furthermore, the clamping device preferably has a ratchet function with release device, so that a simple attachment of the tree is possible and that this clamping device can be easily solved again.

The particular advantage of the stator according to the invention lies in the very simple handling and in a very simple structure. The only traction means, in particular a traction cable made of steel wire or plastic or the like, wraps around the tree at an angle of at least 300 or approximately 360 degrees. Optionally, the traction means may also multiply, i. wrap around a wrap angle of, for example, 720 degrees or more. In this case, only locally limited forces occur, which do not lead to any appreciable material loads or twisting phenomena in the upright area and / or in the case of the holding elements or their anchoring in the base region of the upright. The largest rope forces act between the tensioning device and the next this arranged gripping arm, in which the traction means is guided. For the technical function of the tree stand, it is thus sufficient if only this relatively small area is sufficiently stable.

The reduced strength requirements allow a weaker dimensioned clamping device than in the known tree stands. The stator construction can also be made more economical and simpler in terms of material properties and manufacturing outlay than known constructions.

The large wrap angle or the multiple convolutions lead to a relatively low cable force, so that the clamping device can be operated with significantly less effort. At the same time, however, it creates a great blocking power for the tree. Nevertheless, the component stability can be reduced without problems, which allows a more cost-effective production. The rope tensioning system works optionally without toothing. Instead of a stable steel cable, a lighter and less expensive plastic cable can be used without any problem. The jig has because of the translation on a much better dosing. If a steel cable is used, it may have a very small diameter of less than 1 mm.

The clamping force acts essentially within the cable loop of the traction device, while in the previously known tree stands the entire claw system is pulled onto one side of the tree stand, wherein the stand is exposed to considerable forces and deformations.

The large wrap angle leads to frictional effects between the cable guides and the traction means, so that the cable force is substantially reduced at the rope end anchored in a tensioning element. As a result, the free end of the rope can be secured and countered much easier, for example by simply hooking in the claw. This does not necessarily have to be reinforced, but can be made entirely of plastic. The self-locking of the rope leads to a secure anchoring of the tree in the stand, at the same time the rope forces are significantly reduced. Moving or moving the entire clamping unit is very effectively prevented. That is, the retaining claws are better blocked or secured against displacement.

Another advantage resulting from the clamping technique described with only one pull rope, is the possibility of single-shell or one-piece design of the base and the inner part and the ability to form the receiving area as down and closed on all sides shell. The one-piece design of the tree stand allows a particularly cost-effective manufacturability, for example. By means of an injection molding process. In the same way, the clamping elements and their brackets can be made in one piece from plastic injection molding. The entire building stand can thus be modular and be mounted within a short time, without the need special tools are necessary. If no plastic is to be used for the tree stand, so the shell can be easily made of glass, ceramic, clay, wood, concrete or metal or other suitable material.

The one-piece construction has the additional advantage that the base area can be freely designed within wide limits. The base region may, for example, have a star-shaped contour, which is particularly advantageous for a Christmas tree stand. The corners of this star-shaped floor plan can additionally serve to improve the stability of the stand, so that its total volume is less than a cup-shaped stand, which has the same stability and stability.

The schematic perspective view of Figure 1 shows a preferred embodiment of a tree stand 10 according to the invention having a base portion 12 and a centrally disposed therein, hollow cylindrical receiving portion 14 for a lower trunk portion of a tree to be fastened (not shown) or another rod-shaped body. The base portion 12 has in the embodiment shown a hexagonal contour, which is reminiscent of a poinsettia. However, this contour is only to be understood as an example. Basically, the base portion 12 may have almost any contours and floor plans, as long as the desired function is achieved. On the surfaces 121 of the corners 122 of this star contour decorative elements 123 are arranged in the form of small, raised stars, which may be painted or colored with yellow or golden color or with another color, if necessary. These Decorative elements 123 can optionally also be produced in a hot embossing print. Metal effects can be produced by metallized printing foils. Even mother-of-pearl effects or special structures (eg holograms) are made possible by this. When coloring the tree stand 10 in green color, the decorative elements 123 can offer an attractive visual contrast.

At an upper peripheral edge 141 of the receiving area 14 four retaining elements 16 in the form of claw-like, pivotable gripping arms 18 are arranged, with the aid of a tree to be anchored firmly in the tree stand 10 can be clamped. The gripper arms 18 are each pivotable about a horizontal pivot axis 20, which are arranged approximately tangentially to the upper cylindrical edge 141 of the receiving area 14. The gripper arms 18 are each pivotable in a plane which are arranged perpendicular to the pivot axes 20 and parallel to a longitudinal axis of a tree. The pivot planes of the four gripper arms 18 each meet in the center of an imaginary central axis through the receiving area 14. This imaginary central axis can coincide with optimally centered tree with its longitudinal central axis.

The gripping arms 18 have in the illustrated embodiment, in each case at their free ends 24 a tip 26, which penetrate into the trunk of the tree when pressing against the tree gripping arms 18 and can dig there firm. Optionally, instead of just one tip 26, jagged contours (compare FIGS. 21 and 22) or corrugated structures may also be provided, which each allow a stable non-positive connection with the tree to be anchored.

The four pivotable gripping arms 18 each have, in an area slightly above their center, an approximately horizontally extending guide channel 28 for a pull cable 30, which can be put under tension with a tensioning device 32 and caught up. In the embodiment shown, the clamping device 32 may, for example, be coupled to a corner of the star-shaped base region 12, so that this corner indicated in FIG. 1 can function as a retractable lever. For tensioning the traction cable 30, the lever can, for example, be operated with the foot and act together with a ratchet device or the like, which ensures tensioning of the traction cable 30.

When recovering or tensioning the traction cable 30 by means of the tensioning device 32, the gripper arms 18 are moved in the direction of the vertical center axis, since a free end of the traction cable 30 is locked in one of the gripping arms 18. In the same gripping arm 18 is another guide channel below the first guide channel 28, from which a connection to the clamping device 32 is made. The pull cable 30 is thus tensioned between the tensioning device 32, a deflection 124 in the base region 12, the gripping arm 18 with the two guides and the other three gripping arms 18.

The clamping device 32 is indicated in the embodiment shown as a foot lever 321, which may be formed in one of the six corners 122 of the base portion 12. Optionally, the foot lever 321 may be arranged in the immediate vicinity of one of the holding elements 16, namely with the two guide channels, as indicated in FIG. The foot lever 321 is assigned in this case, the deflection 124 in the base region 12. An alternative arrangement of the foot lever 321 is additionally indicated in FIG. Thus, this can also be arranged in a region between two adjacent holding elements 16.

FIG. 1 additionally illustrates a preferred embodiment of the tree stand 10, in which the base region 12 and the receiving region are formed as a common, closed component. The receiving area 14 forms an upwardly open, but closed to all sides and down pot, which is waterproof and thus can be filled to the top with water. This comes with neither the pull cable 30 nor with parts of the clamping device 32 into contact.

The function of a water level indicator 142 arranged at the upper edge 141 of the receiving region 14 will be explained in more detail with reference to FIGS. 30 to 33.

FIG. 2 illustrates in a further schematic perspective illustration a slightly modified variant of the tree stand 10 according to the invention, in which the foot lever 321 of the tensioning device 32 is arranged between two corners 122 of the base region 12. The deflection 124 for the pull cable 30 is in this case arranged to the right of the corresponding holding element 16, which is equipped with two guides.

The openings 181 between the rear sides 182 of the gripper arms 18 and the surface 121 of the base portion 12 are designed so narrow that thus each an anti-trap is formed. Preferably, the front sides 183 of the gripping arms 18, which are directed towards the receiving region 14, are also designed so that in each case an anti-pinch protection is formed.

Also in the variant according to FIG. 2, the base region 12 and the receiving region 14 are formed again as a common, closed-down shell, so that the tree stand 10 forms a watertight pot. The rest of the construction corresponds to the variant of the tree stand shown in FIG.

The sectional view of Figure 3 illustrates in a schematic manner the arrangement of the holding elements 16 formed by the gripping arms 18, which are each pivotally mounted on the edge 141 of the receiving area 14. Based on this figure, the closed design of the receiving area 14 is clearly visible. The holding elements 16 are each mounted in inserts 34, which are inserted in the vertical direction from above into matching receiving pockets 36 and there by means of latching spring tongues 40 there can be largely locked without play. Alternatively, the inserts 34 may be glued or pressed in the receiving pockets 36. If required, these snap connections shown can be released again by pressing in the spring tongues 40 through the latching openings 361, so that the inserts 34 together with the gripper arms 18 mounted pivotably therein can be removed upwards.

The base portion 12 is provided in the illustrated embodiment with additional stiffening ribs 125, which can increase the stability and torsional rigidity of the tree stand 10. The entire base portion 12 with the stiffening ribs 125 and the receiving portion 14 together with the receiving pockets 36 for the inserts 34 consists of one piece. The tree stand 10 may in particular be made of injection-molded plastic, which can be produced easily and inexpensively in the desired shape.

Centered in the flat bottom region 143 of the receiving region 14 is a centering device for a tree to be clamped in the form of a centering tip 50 arranged. This may, for example, consist of metal and is cast to prevent leaks in the plastic of the bottom portion 143.

For fixing the clamping device 32 (not shown) serve Befestigungsdome 126, where the clamping device 32 anchored, in particular can be screwed.

On the underside of the tree stand 10 can be provided 127, which can, for example, by foaming by means of polyurethane o. The like. Can be provided. These stand surfaces 127 can be advantageously mounted during the injection molding process of the base and receiving area 12, 14, for example by means of a two-stage injection molding process. Due to the footprints 127 can be dispensed with a separate floor, which would have to be added later after the clamping device 32 and optional ballast elements (not shown) were mounted and mounted.

The further sectional view of Figure 4 illustrates the tree stand 10 with mounted clamping device 32, which is formed from a mounting plate 322 and pivotally mounted thereon the foot lever 321. The mounting plate 322 is screwed from below to the Befestigungsdome 126. A ratchet device 323 has a gear 324 and a latch lever 325 engaged therewith, which is displaceable against spring force and due to the beveled tooth flanks of the gear 324 at a defined load for slippage of the foot lever 321 provides, without the pull cable 30 further wound and so that it is more tense. The function of the ratchet device 323 will be explained in more detail with reference to FIGS 29 to 44.

The schematic representation of Figure 5 illustrates one of the gripper arms 18 which is pivotally mounted in the insert 34. After connecting the insert 34 and the gripping arm 18, the insert 34 can be anchored in the receiving pocket 36 provided thereon on the cylindrical inner lateral surface of the receiving region 14 (compare FIGS. 3 and 4). The gripper arm 18 is biased about a leg spring 38 in approximately vertical position, so that when set under tension pull cable 30 is a movement towards the tree out is possible. Once the tensioning device 32 is released and the tension of the pull cable 30 is released, the gripping arm 18 is through the restoring force of the leg spring 38 is returned to its initial position corresponding to FIG.

In addition, the arrangement of the spring tongue 40, which is resiliently arranged on a flat side of the parallelepiped-shaped insert 34, is illustrated with reference to FIG. At the free end of the spring tongue 40, a latching lug 401 is arranged, which projects beyond the outline of the insert 34 in the relaxed state of the spring tongue and which is snapped into the latching opening 361 in the fully inserted in the receiving pocket 36 state of the insert 34. According to an alternative, not shown here, however, two identical spring tongues 40 may optionally be arranged parallel to each other, whereby the basically same function is fulfilled. In such an arrangement, two juxtaposed detent openings 361 must be provided in the receiving pocket 36, in which the detents 401 of the spring tongues 40 can engage. With such a variant, the reliability of the locking connection against falling out of the inserts due to the double latching of the two spring tongues 40 can be easily increased.

Furthermore, Figure 5 illustrates the finger or Einklemmschutz, which is formed by a Abdecknase 341, which rests on the outer periphery of the leg spring 38 and this partially covers. The Abdecknase 341 protrudes from the upper edge of the inner flat side of the insert 34, on which the spring tongue 40 is fixed, in the direction of the gripper arm 18 upwards and thus forms during pivoting of the gripping arm 18 a reliable anti-trap, since the resulting gap between Abdecknase 341 and thigh spring 38 is so narrow that no finger fits between them. Optionally, this Abdecknase 341 instead of the insert 34 may be formed on the shell 14.

Cover discs 184 on the gripper arm 18 act as a lateral anti-trap as they cover the axial sides of the leg spring 38. A pivot stop 342 on the inner frame of the insert 34 provides for limiting the maximum pivot angle of the gripper arm 18 in its pivotal movement about the pivot axis 20th

The gripper arm 18 is slightly curved inwardly towards its upper tip 26 at the free end 24, which offers advantages in terms of increased clearance for the tree to be clamped. This can be astrests or adhesions in the Have lower clamping range, without thereby the function of the tree stand 10 is significantly limited. In addition, the inward-pointing tip 26 improves the leverage ratios for relatively thin trunks, since the pull rope 30 is located relatively high up when gripping arms 18 are fully clamped against the tree. The pull cable 30 can thus exert a sufficient clamping force even with relatively close together pulled gripping arms 18.

The schematic representations of Figures 6 and 7 each show a preferred embodiment of the insert 34, on the pivot axis 20 of the gripper arm (not shown) is mounted. The leg spring 38 is coaxially disposed about the axis 20 so that it can provide the desired bias of the gripper arm.

FIG. 8 shows a view corresponding to FIG. 6 without the leg spring. FIG. 9 shows a view corresponding to FIG. 7, likewise without the leg spring.

The gripper arm 18 is mounted in an axis 41 which is anchored to the two narrow sides of the insert 34. The axis 41 can be inserted as soon as the gripper arm 18 and the leg spring 38 are positioned at their intended installation location. The side view of Figure 6 illustrates the previously mentioned pivot stops 342, which are each arranged below the axle stub 42 and limit the maximum pivoting range of the gripping arms 18 in their pivotal movement in the direction of the clamped stem section.

On the basis of the schematic representation of Figures 6 to 9, the design of the Abdecknase 341 is again illustrated, which forms the anti-trap. Furthermore, there is an additional length stop clarifies that defines the exact insertion position of the insert 34 in the receiving pocket 36. For this purpose, on the one hand the Abdecknase 341 has a raised lower edge, which projects beyond the flat side of the insert 34 and which rests at fully inserted insert 34 at an upper edge of the receiving pocket 36 and the upper edge 141 of the receiving area 14. The same function is formed by latching projections 343, which are located at the lower edges of the two narrow sides of the insert 34, which carry the axis 41.

The spring tongue 40 with the locking projection 401 arranged thereon protrudes from the flat side of the cuboid insert 34. The insert 34 can be pushed in a vertical direction from above into the slot 36 in the receiving region 14. By means of the spring tongue 40, the insert 34 can be locked in the respective receiving pocket 36 and secured against withdrawal. The receiving pocket 36 can thus be taken into account in an injection molding process for the production of the base region 12 of the tree stand 10, without the need for time-consuming reworking. A particular advantage of such receiving pockets 36 is the possibility of up to the edge 141 towards closed, trough-like design of the receiving area 14, which allows filling with water to the upper edge.

Instead of the leg spring 38, the bias of the gripping arms 18 can be applied in other ways, for example. By a tension spring 44 or by a compression spring 45, as illustrated with reference to FIG. Both springs 44, 45 can be used simultaneously. Alternatively, it may also be sufficient to use either only one tension spring 44 or only one compression spring 45.

The perspective view of Figure 11 illustrates an alternative embodiment of an insert 34, in which instead of an axis for supporting the gripping arm 18, two short shaft shoulders 42 are provided, which are each mounted in the insert 34. The round shaft shoulders 42 engage in each case in corresponding round receptacles 344 of the same diameter. To insert the gripper arm 18 in the receptacles 344, the flat sides of the insert 34 are slightly bent apart. Optionally, in this embodiment, a leg spring 38 or a tension spring 44 and / or a compression spring 45 may be provided. The bias for the gripper arm 18 may be selectively applied by a leg spring, a tension spring, a compression spring mounted on the other side of the insert 34, or any combination of these springs.

The mutually corresponding pivot stops 185 and 342 on the gripper arm 18 and on the insert 34 respectively limit the maximum pivoting angle of the gripping arm 18 in both directions.

The schematic representation of Figure 12 illustrates a variant of a cable guide within one of the gripping arms 18. In addition to the horizontally extending guide channel 28 for the pull cable 30 near the upper free end 24 of the gripping arm 18, at least one of the gripping arms 18 has an additional channel 46 for cable guidance, the at least partially extends in a vertical or obliquely downwardly inclined direction, as indicated in Figure 12. There, the additional channel 46 has a curved course. The channel on the claw inside serves for anchoring and / or for the implementation of the rope, for example. When attaching the rope end in the stand. The channel on the outside of the claw serves to carry the rope.

A possible course of the channel 46 and its arrangement with respect to the horizontal guide channel 28 will be clarified again with reference to FIGS 16 to 20. A part of the channel wall can bulge out of the rear side 182 of the gripping arm 18, as indicated in FIG. The gripper arm 18 according to the illustrated design is suitable for use in a variant of the tree stand 10, in which the clamping device 32 is approximately aligned with the gripping arm 18, which has the double cable guide.

An alternative variant of the gripper arm 18 is shown in Figures 13 to 15. The additional channel 46 here has a uniformly curved and symmetrical to the pitch longitudinal plane of the gripping arm 18 course. This variant of the gripping arm 18 is suitable, for example, for use in a tree stand 10, as shown in FIG. Here, the deflection 124 is arranged for the pull cable 30 adjacent to one of the gripper arms 18, so that the clamping device 32 is positioned next to the gripping arm 18. The traction cable 30 extends here between the tensioning device 32, the deflection 124, the curved channel 46 of the deflection 124 nearest gripper arm 18 and the horizontal guide channels 28 of the remaining gripper arms 18, as shown in Figure 2. The free end of the traction cable 30 is anchored in the gripping arm 18, which is arranged next to the deflection 124. This gripper arm 18 thus has a double cable guide. Optionally, the free end of the pull rope can also be fixed to the stand.

The schematic representations of Figures 12 and 16 to 20 respectively illustrate the curved course of the channel 46, on the narrow side of the gripping arm 18 in the horizontal direction and in the direction of the pivot axis 20 in a vertical or inclined obliquely downward direction. The horizontal guide channel 28 may be formed continuously from one narrow side to the other, so that the channel 46 branches off from the guide 28 (Figure 12). Alternatively, the guide 28 may be formed in the gripper arm 18 which is provided with the additional channel 46, as a blind hole, since this portion of the guide 28 is used to anchor a free end of the traction cable 30, which is countered in the gripper arm 18 (FIGS 16 to 18).

The schematic representations of Figures 16 to 18 illustrate an embodiment of the gripping arm 18, in which the horizontal guide channel 28 has a slot-like opening 48, which can serve, for example, for locking the free end of the traction cable 30. In the opening 48 can, for example, a suitably slotted ring (not shown) are inserted, with the aid of the pull cable 30 can be fixed in the gripping arm 18. FIG. 18 illustrates the guide channel 28 of the gripper arm 18, which is embodied as a blind hole and thus does not extend from one narrow side to the other, but is open only to a narrow side. To the opposite narrow side of the curved channel 46 opens, which does not cross in this variant with the guide channel 28 or cuts. The rear view of Figure 18 further illustrates a possible course of the channel 46 which extends from a narrow side of the gripping arm 18 in a curved course vertically downwards and can open in a rear side disposed in the gripping arm 18 opening 461, which serves to carry the pull cable 30 to to anchor it in the stand or to mount it in the tensioning device.

FIG. 19 additionally illustrates the course of a further channel 462, which initially describes a downward curved course from the upper side of the gripping arm 18 and finally opens into a vertical section on the inside of the gripping arm 18. This vertical section is used for hooking and countering a free rope end of the pull rope, which thus can be clamped there. The rear opening 461 for taking out the other end of the rope, which is guided to the tensioning device is shown in dashed lines in Figure 19 and in solid line in Figure 20.

The course of the pull cable 30 shown makes possible a countersunk and almost invisible arrangement of the pull cable 30 in the area between the deflection within the gripper arm and the tensioning device arranged closest to the clamping device.

Figures 21 and 22 illustrate a further alternative variant of the gripper arm 18, which may have a plurality of tips 26 at its free end 24. The juxtaposed tips 26 can provide an even more reliable anchoring of a rod-shaped object or tree, since it can also slip and yet be held securely.

Further embodiments of gripper arms 18 are illustrated with reference to FIGS 23 to 26. In this case, FIGS. 23 and 24 each show a gripping arm 18 which, for example, can consist of injection-molded plastic or the like, and which has tips 261 formed on the free end 24. The molded-in tips 261 each have an approximately cylindrical, but preferably slightly conical portion and a conical, more or less rounded, pointed portion which protrudes from the gripping arm 18 at the free end 24 and ensures a better fixation of the object to be anchored. The molded-in tips 261 may consist in particular of metal, for example of stainless steel or brass or the like, so that not only a better fixation of the object to be anchored can be ensured thereby. In addition, the molded-in tips 261 made of metal provide an advantageous appearance, which suggests the user a high quality and solidity. The molded-in tips 261 can claw in a tree to be anchored in an advantageous manner in the bark and thus ensure a secure anchorage even at relatively low clamping forces. Optionally, two, three or more similar or slightly different from each other in shape or size molded tips 261 may be disposed at the free end 24 of the gripping arm 18.

Figures 25 and 26 show an alternative embodiment of a gripping arm 18 with a molded metal or plastic insert 262 having two, three or more outwardly facing tips 263 which dig into the outer circumferential surface of the article to be anchored as soon as the gripper arms 18 of the pull cable 30 are braced against each other. Figure 26 illustrates a possible embodiment of the insert 262 before its installation and its arrangement in the installed state, just as shown in Figure 25. In this variant too, the tips 263 of the molded insert 262 made of metal provide an advantageous appearance, which suggests a high value and solidity to the user. The outwardly projecting tips 263 can claw in a tree to be anchored in an advantageous manner in the bark and thus ensure a secure anchorage even at relatively low clamping forces. Optionally, the insert 262 may have two, three, or more like or slightly divergent tips 263 in shape or size.

FIGS. 27 to 29 show a sleeve 301 which can serve for locking a free cable end 302 in a gripping arm 18. The sleeve 301 has an annular shoulder 303 and a slightly tapered shank 304. A longitudinal slot 305 extends over the entire length of the sleeve 301. The longitudinal slot 305 opens into a central passage 306, in which the pull cable 30 comes to rest. The passage 306 is widened in the region of the paragraph 303 in diameter, so that a nipple 307 attached to the cable end 302 can be accommodated therein, as illustrated in FIG.

Figures 26 to 28 show a possible embodiment of a water level indicator 142 (see Figures 1 and 2), which is formed of a hollow cylindrical and closed at the upper end 143 143 float body. The elongated float body 144 can be displaced in the vertical direction in a corresponding receptacle on the edge of the receiving region 14 (see FIG. The volume of air trapped within the float body 144, which is open at the bottom, provides buoyancy as soon as the receiving area 14 is filled with water. A flattening 145 on the outer circumference of the float body 144 forms an anti-rotation device with the correspondingly shaped receptacle.

The vertical stroke of the float body 144 is limited by a stop web 146, which is movable up and down in a slit-like opening 147 directed towards the receiving region (see FIGS. 1 to 4 and FIG. The opening 147 simultaneously forms an open connection for receiving the water level indicator 142, which thus together with the water level in Pick-up area 14 moves up or down. The reservoir in which the water level indicator 142 moves, however, is closed to the outside, so that no water can escape.

Optionally, the float body 144 may also have a closed volume, which, however, must have a lower density than water so that the float body 144 floats on the water. The float body 144 may, for example, consist of a suitable plastic, for example. Foamed polyurethane.

The float body 144 may optionally have on its outer circumferential surface varying colors or markings, which are arranged, for example, halfway up and thus facilitate the exact reading of the respective water level.

An additional leakage protection for emerging from the receiving area 14 water can be illustrated with reference to Figures 1 and 2. In order to prevent overflow of water when the receiving area 14 is too full, the inner area of the upper side 121 of the tree stand 10 is recessed, so that the water first collects in this trough-like area 148 before it passes over the edge and can moisten the floor , In the case of wooden floors, an unnoticed overflow of the water reservoir in the tree stand 10 could otherwise lead to water damage.

The filling with water is typically carried out by first filling so much water in the receiving area 14 until the water level indicator 142 responds. Subsequently, water can be replenished until the upper flooding surface of the trough-like region 148 is flooded.

The trough-like region 148, which surrounds the receiving region 14 at the upper edge 141, may optionally have a round or otherwise shaped diameter, which must be significantly larger than the diameter of the receiving region 14 in order to fulfill its intended function. However, the trough-like region 148 can also accommodate the outer contour of the tree stand 10 and be designed star-shaped, wherein preferably a parallel structure to the outer contour of the tree stand 10 is formed, as shown in the figures.

In order to reliably prevent up to the upper edge filled with water receiving area 14 that the water through the channel 124 to deflect the pull cable 30 and, for example, run down or can penetrate into the base portion 12 of the tree stand 10, which has in the Figures 34 to 37 shown embodiment of the tree stand 10 has a raised cable outlet 129, the opening 130 is arranged to the base region 12 above the upper edge of the trough-like region 148. In this way, can be prevented as far as possible that inadvertent filling with water can lead to an uncontrolled and unnoticed overflow and leakage of water down, which u.U. can lead to damage to the soil, for example, in a wooden floorboards or parquet.

A similar variant with an increased cable outlet 129 with an opening 130 for the pulling cable arranged above the trough-like region 148 is also shown in FIGS. 48 and 49. However, the cable exit 129 does not open here horizontally or flatly inclined, but approximately vertically. Due to the outwardly rounded opening 130, however, the traction cable 30 can slide along the edge of the opening 130 without significant friction, so that the opening 130 simultaneously acts as a deflection for the traction cable 30.

Figures 29 to 44 show possible embodiments of a clamping device 32, which serves to tension the pull cable 30 and thus for fixed clamping a tree to be fixed by means of the pivoted in the direction of the central axis of the tree stand support members 16 (Figures 1 to 4). FIGS. 29 to 32 show different views of a first variant of the tensioning device 32, in which the ratchet device 323 is formed from the foot lever 321, which is pivotably mounted and provided with a toothed wheel 324, and the displaceable pawl lever 325.

The foot lever 321 is mounted in a frame 326 which is formed by two plate cheeks connected to the mounting plate 322. The foot lever 321 is mounted on a shaft 327, the extension of which is designed as a cable drum 328, on which the tension cable 30 is wound upon actuation of the tensioning device 32. In FIGS. 29 to 32, only a short piece of the traction cable 30 is shown, which is guided by the receptacle 124 (FIGS. 1 to 4) in the upper side of the base region 12.

On the shaft 327, the gear 324 is further mounted rotatably, which is normally in engagement with the foot lever 321 via the pawl lever 325 (see Figure 42). When the foot lever 321 is tensioned in the direction of the arrow, the pawl lever 325 engaging in one of the tooth flanks of the toothed wheel 324 (see Figure 38) ensures a force transmission of the lever movement to a corresponding shaft rotation, whereby the pull cable 30 is wound onto the cable drum 328. A return movement of the lever 321 is easily possible due to the much flatter in this direction tooth flanks, whereby the Ratschweff is achieved. Once the cable tension exceeds a threshold, the slightly slanted tooth flanks, in cooperation with the tapered engagement portion of the pawl lever 325, provide movement toward the free end of the foot lever 321 against the force of a tension spring (not shown). This anti-skid device limits the maximum cable tension to a preset value at which the tree is securely anchored by means of the gripper arms.

This provides an overload protection for the entire system, which can protect the clamping system, the clamping claws and the shell construction from overloads and possible fractures. Due to the achieved limitation of the total forces occurring, the required wall thickness of the stand can be reduced. Overall, the cost of materials can be reduced or different materials can be used. Also, the manufacturing and material costs for the tree stand can be reduced.

Since the pawl lever 325 cooperates with a slide 329 on the frame 326 (see Figure 1), the maximum pivot angle of the foot lever 321 is limited in both directions. To release the pull cable 30, a lock 330 can be released, whereby the power transmission from the lever 321 is lifted onto the shaft 327. The traction cable 30 is unwound from the rope drum 328 by the gripping arms 18 moving back into their relaxed starting position.

FIG. 44 shows an alternative embodiment of the tensioning device 32, which has a modified ratchet device 323. The pull cable 30 is wound in the same way on a cable drum 328 connected to a shaft 327. The shaft 327 is mounted in the frame 326 which is connected to the mounting plate 322. The tensioning of the traction cable 30 takes place during pivoting of the lever 321 the tilting of the two resiliently mounted plates 331 against the circumference of a disc 332, which rotates with the shaft 327. The upper plate 331 mounted or clamped in the foot lever 321 serves to tension the pull cable 30 during the movement of the foot lever 321 downwards. For this plate 331 a fixed stop 333 is provided, which leads to the lifting of the sheet 331, as soon as the foot lever 321 is pivoted upwards. The clamped in the frame 326 bottom plate 331 forms a backstop, which prevents the shaft 327 from turning back. The foot lever 321 itself is pulled in each case with a return spring 334 in its upper position, as soon as it is released after a clamping operation.

The illustration of FIG. 45 shows a further alternative embodiment of the tensioning device 32, in which the locking mechanism 330 is actuated by a lever 335 which can be pivoted in two directions and which is arranged on the outside of the foot lever 321. The lever can be moved between two end positions marked "OPEN" and "SAFE". In the middle position, the foot lever 321 by pressing down the tension cable 30 stretch, since in this way the ratchet device 323 is actuated. As soon as the pull cable 30 is sufficiently tensioned, the lever 335 can be moved into the secured end position "SAVE", so that unlocking is not possible even if the lever 321 is actuated unintentionally. Only by pivoting the lever 335 in the end position "OPEN" can the foot lever 321 provide by pivoting upwards for a solution of the ratchet device 323 and for a relaxation of the hawser 30.

The operability of the lever 335 is the same as with firearms, so that the operating logic opens up directly and intuitively, without special considerations are necessary.

The partial sectional views of FIGS. 46, 47 and 48 again show the modular construction of the tensioning device 32, which as a whole can be connected to the base region 12 of the tree stand 10, for example by screwing.

The perspective cross-sectional view of Figure 50 illustrates the structure of the tree stand 10, which has a series of struts between the outer housing flanks and the inner receiving portion 14 (see Figures 1 to 4). These struts or stiffening ribs 125 serve to stabilize the structure and to support the forces when clamping a tree on the Holding elements 16 and on the restraints (insert 34, receptacle 36) act. The cavities 128 located between the stiffening ribs 125 can optionally be used for filling with ballast bodies (not shown) in order to give the tree stand 10 a greater weight and thus better stability.

FIG. 51 shows the tree stand 10 in a view from below with already mounted clamping device 32.

With reference to FIGS. 50 and 51, it is again made clear that the base region 12 of the tree stand 10 can be designed in an integrated construction with the receiving region 14 and the receiving pockets 36 for the stable anchoring of the holding elements 16. The tree stand 10 can be made very inexpensive thereby in one piece design. These parts can be made in a single operation of plastic, in particular by means of an injection molding. Likewise, the retaining elements 16, i.e., the gripping arms 18 and their inserts 34, can each be made of injection molded plastic. If this is necessary for reasons of higher strength, then some of these parts may possibly be provided with a fiber reinforcement.

Furthermore, FIGS. 52 to 58 show alternative embodiments of the base region 12, in which in each case more or fewer stiffening ribs 125 establish a radial connection between the receiving region 14 and the outer enveloping wall or outer wall 131 of the base region 12. The radial stiffening ribs 125 preferably each have a height that corresponds to the height of the base region 12. At their upper edge they are connected to the top of the base portion 12, so that a very rigid composite is formed.

The stiffening ribs 125 of the variant shown in FIG. 52 extend in each case in a straight line from the outer edge of the receiving region 14 to the tips of the star-shaped base region 12. The same applies to the embodiment variant according to FIG. 53, additional stiffening ribs 125 being provided here, each centered between the already existing stiffening ribs 125 are arranged and which in each case extend from the receiving region 14 to the inner edges between two adjacent teeth of the star-shaped outer wall 131 of the base region 12.

In the variant according to FIG. 54, serpentine connecting ribs 132 are provided, which produce a stiffening connection between respectively adjacent stiffening ribs 125. In the variant according to FIG. 55, grid-like connecting ribs 132 are provided, which are each arranged in a grid-like manner between adjacent, radially arranged reinforcing ribs 125. In the variant according to FIG. 56, in each case two parallel connecting ribs 132 are provided between respectively adjacent, radially outwardly pointing stiffening ribs 125. The view of Figure 57 illustrates that the height of the connecting ribs 132 may be less than that of the radial stiffening ribs 125. Like these, however, the connecting ribs 132 at the upper edge into the horizontal bottom of the base portion 12 and are formed there. The perspective partial sectional view of Figure 58 illustrates again an advantageous arrangement of stiffening ribs 125 and connecting ribs 132 which causes maximum stability and rigidity at very low weight of the base portion 12. The ribs 125, 132 allow the use of very small wall thicknesses without sacrificing stability.

The desired stability of the tree stand 10 can be made by appropriate ballast weights (not shown), by filling the cavities of the base portion 12 with water, sand or other suitable materials, wherein in liquid or free-flowing ballast elements or materials a closed bottom (not shown) is necessary, for example, screwed to the base portion 12, glued or otherwise connected. Optionally, the floor can be glued, welded, bolted, snapped or locked, pressed or riveted. Combinations of these types of attachment are possible.

Optionally, the bottom may have a central recess corresponding in size to the outer diameter of the receiving area 14 so that it can pass through the ground.

Figures 59 to 62 show different embodiments of a centering system for the tree. The centering ring 52 according to FIG. 59 has a circumferential tire 521, on which a plurality of webs 522 are arranged, which serve to guide differently contoured tree trunks. The webs 522 indicate their upper narrow sides in each case an inwardly inclined chamfer 523, which serves to better guide a tree to be used.

Figure 60 shows a closed centering ring 54 having an inwardly inclined upper end face 541, which serves to guide the tree.

The centering 56 according to the figures 61 and 62 also serves for centering and guiding a tree to be fixed. The centering shell has a flat bottom 561 and three inclined side surfaces 562, which merge upward into a cylindrical contour 563.

The centering rings 52, 54 and the centering 56 can be made in different dimensions and inserted as needed in the receiving area 14.

The shown centering arrangements according to FIGS. 59 to 62 show only exemplary embodiments. Alternatively or additionally, a centering mandrel may be provided, which is preferably arranged centrally in the vertical direction at the bottom of the receiving area 14. Optionally, several centering mandrels can be provided.

The illustration of Figure 1 illustrates the apparently within a closed ring (or more closed rings in multiple wrapping) between the gripping arms 18 and in their guides 28 extending traction cable 30, the course between this seemingly closed ring and the clamping device are designed almost invisible can. Also, the fixation of the free end of the hawser in the provided with the curved channel gripper arm 18 supports this hidden installation of the hawser. Of course, even with an anchoring of the free end of the pull rope in the stand area whose course be hidden or hidden.
