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.

A disadvantage of many known systems is the relatively complex handling, which makes the anchoring of a tree tedious and time consuming. In the known systems with traction device considerable forces are necessary for tensioning the traction device, since otherwise the tree is not securely anchored.

An object of the present invention is to provide a tree stand which enables safe and fast anchoring of a tree with little effort.

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 area and can be pivoted about a horizontal axis in a plane perpendicular to the longitudinal axis of the rod-shaped object or tree, said holding elements being pivotable by means of a single traction means guided in the holding elements Active connection is against the circumference of the rod-shaped object or the trunk portion of the tree are clamped. According to the present invention, one end of the traction means is clamped in the tensioning device; while the other end is fixed or countered in one of the holding elements. The traction means is mounted in the form of a rope loop in the holding elements.

The stand according to the invention with the features of claim 1 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 retention properties of the tree stand according to the invention. The pulling means guided in the form of a lasso loop or rope loop (or in the form of a tie knot) or in several loops in the holding elements and pulling them together 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 retaining elements according to the invention means that very high blocking holding forces can 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 setup the superiority of this new clamping system could be checked and proved. 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 between a pivot axis and an upper free end of the holding element is arranged. 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 unduly high, resulting in relatively high friction losses due to the leadership properties of ropes and thus to increase the necessary Clamping force would result.

According to an embodiment 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 a non-inventive embodiment, 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 does not necessarily need very high Tensile loads be designed because 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 can cooperate with a lower end face of the stem portion, may 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.

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. A particularly advantageous variant of the tree stand according to the invention provides a one-piece design of the cup-shaped receiving area for the tree with the base area, which can be produced, for example, by means of an injection molding process.

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-like container of the receiving area and an outer housing shell or the base area can optionally made of plastic or be made of metal. Optionally, the container and the outer shell and / or the base portion may also be made of 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. These ballast pieces may possibly be integrated in 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. Also, the stator construction can with regard to the material properties and in terms of Manufacturing effort to be carried out more economical and easier 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 Construction of the tree stand allows a particularly cost manufacturability, eg. 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 construction site can thus be modular and assembled in a short time, without the need for 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 area 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 FIG. 1 shows a preferred embodiment of a tree stand 10 according to the invention, which has 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 be produced in a hot embossing. 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 gripping arms 18 are each pivotable in a plane perpendicular to the pivot axes 20 and parallel to a Longitudinal axis of a tree are arranged. 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 (cf. FIGS. 21 and 22 ) or corrugated structures may be provided, each allowing 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 exemplary embodiment shown, the clamping device 32 may, for example, be coupled to a corner of the star-shaped base region 12, so that they are in FIG. 1 indicated corner can act 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 traction cable 30 is thus stretched 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 in close proximity to one of Holding elements 16, and that with the two guide channels, be arranged, as in FIG. 1 is indicated. 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 shown in FIG FIG. 1 additionally indicated. Thus, this can also be arranged in a region between two adjacent holding elements 16.

FIG. 1 also illustrates a preferred embodiment of the tree stand 10, wherein the base portion 12 and the receiving area are formed as a common, closed component. The receiving area 14 forms an upwardly open, but too old sides and closed down pot that 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 arranged at the upper edge 141 of the receiving area 14 water level indicator 142 is on hand of the FIGS. 26 to 28 explained in more detail.

The FIG. 2 illustrates in a further schematic perspective view of a slightly modified variant of the tree stand 10 according to the invention, in which the foot lever 321 of the clamping device 32 between two corners 122 of the base portion 12 is arranged. 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 Again, the base portion 12 and the receiving portion 14 are formed as a common, downwardly closed shell, so that the tree stand 10 forms a watertight pot. The rest of the construction is the same as in FIG. 1 shown variant of the tree stand.

The sectional view of the FIG. 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.

Centrally in the flat bottom portion 143 of the receiving area 14, a centering device for a tree to be clamped in the form of a centering tip 50 is 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 advantageously in the injection molding of the Base and receiving area 12, 14 are attached, 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 the FIG. 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 is on hand of FIGS. 29 to 35 explained in more detail.

The schematic representation of FIG. 5 illustrates one of the gripper arms 18 which is pivotally mounted in the insert 34. After joining 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 circumferential surface of the receiving region 14 (cf. Figures 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 gripper arm 18 is returned by the restoring force of the leg spring 38 back to its original position FIG. 5 brought.

Based on FIG. 5 is also again the arrangement of the spring tongue 40 illustrates that is resiliently disposed on a flat side of the cuboid insert 34. 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, Here, however, not shown variant, 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 clarifies the FIG. 5 the finger or Einklemmschutz, which is formed by a Abdecknase 341 which rests on the outer periphery of the leg spring 38 and this covers partially. 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 may have astrests or adhesions in the 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 FIGS. 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.

The FIG. 8 shows one of the FIG. 6 corresponding view without the leg spring. The FIG. 9 shows one of the FIG. 7 corresponding view, also 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 FIG. 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.

Based on the schematic representation of FIGS. 6 to 9 is again the design of Abdecknase 341 illustrates, 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, in an injection molding process for the preparation of the base portion 12 of the tree stand 10 are taken into account, without elaborate reworking are necessary. 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 may be applied in other ways, for example. By a tension spring 44 or by a compression spring 45, as on hand the FIG. 10 is clarified. 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 FIG. 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 FIG. 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 an additional channel 46 for cable management, at least partially in vertical or sloping downwards Direction runs like this in FIG. 12 is indicated. 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 is again on the basis of FIGS. 16 to 20 clarified. A portion of the channel wall may bulge out of the backside 182 of the gripper arm 18 as shown in FIG FIG. 12 is indicated. 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 gripping arm 18 is in the FIGS. 13 to 15 shown.
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 in the FIG. 2 is shown. Here, the deflection 124 is arranged for the pull cable 30 adjacent to one of the gripping arms 18, so that the clamping device 32 is positioned next to the gripping arm 18. The traction cable 30 runs here between the tensioning device 32, the deflection 124, the curved channel 46 of the deflection 124 closest to the gripper arm 18 and the horizontal guide channels 28 of the remaining gripper arms 18, as shown in FIG. 2 is shown. 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. Not according to the invention, the free end of the pull rope can also be fixed to the stand.

The schematic representations of Figures 12 and 16 to 20 illustrate in each case the curved course of the channel 46 which extends 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 obliquely downwardly inclined 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 ( FIG. 12 ). Optionally, the guide 28 at that gripping arm 18, which is provided with the additional channel 46, also be formed as a blind hole, since this section of the guide 28 serves for anchoring a free end of the traction cable 30, which is countered in the gripping arm 18 ( FIGS. 16 to 18 ).

The schematic representations of FIGS. 16 to 18 illustrate an embodiment of the gripper 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. The FIG. 18 illustrates the trained as a blind hole guide channel 28 of the gripping arm 18, which thus does not extend from one narrow side to the other, but only to a narrow side is open. 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 the FIG. 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 arranged in the gripping arm 18 opening 461, which serves to carry the pull cable 30, this not according to the invention in the stand to anchor or hang in the jig.

The FIG. 19 also illustrates the course of another channel 462, the first of the upper side of the gripper arm 18 describes a downwardly curved course and finally opens in a vertical section on the inside of the gripper 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 dashed in FIG. 19 and in a solid line in FIG. 20 located.

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.

The FIGS. 21 and 22 illustrate another 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.

The FIGS. 23 to 25 show a sleeve 301, which can serve to counter 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 passageway 306 is widened in diameter in the area of the shoulder 303 so that a nipple 307 fastened to the cable end 302 can fit into it, as shown in FIG FIG. 25 is clarified.

The FIGS. 26 to 28 show a possible embodiment of a water level indicator 142 (see. FIGS. 1 and 2 ), which is formed from 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 (cf. FIG. 26 ). 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 in a slot-like opening directed towards the receiving area 147 (see. FIGS. 1 to 4 and FIG. 26 ) is movable up and down. The opening 147 simultaneously forms an open connection for receiving the water level indicator 142, which thus moves up and down together with the water level in the receiving area 14. The reservoir in which the water level indicator 142 moves, however, is closed to the outside, so 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.

An additional leakage protection for emerging from the receiving area 14 water can be found on the basis of FIGS. 1 and 2 be clarified. 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 in a trough-like manner, so that the water initially collects in this area before it passes over the edge and can moisten the floor. Especially with wooden floors otherwise unnoticed overflow of the water reservoir in the tree stand 1 0 could lead to water damage.

The FIGS. 29 to 35 show possible embodiments of a clamping device 32, the tension of the hauling rope 30 and thus for firmly 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 (FIGS. FIGS. 1 to 4 ) serves. The show FIGS. 29 to 32 different views of a first variant of the clamping device 32, in which the ratchet device 323 is formed from the pivotally mounted and provided with a gear 324 foot lever 321 and the movable latch 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 the FIGS. 29 to 32 is drawn only a short piece of the traction cable 30 through the receptacle 124 ( FIGS. 1 to 4 ) is guided in the top of the base portion 12.

On the shaft 327, the gear 324 is further rotatably mounted, which is normally with the foot lever 321 via the pawl lever 325 is engaged (see. FIG. 33 ). If the foot lever 321 is tensioned in the direction of the arrow, then the latch lever 325 engaging in one of the tooth flanks of the toothed wheel 324 (see FIG. FIG. 29 ) for 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 latch lever 325 at the same time with a gate 329 on the frame 326 cooperates (see. FIG. 1 ), the maximum swing 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 angled away from the cable drum 328 by the gripper arms 18 moving back into their relaxed starting position.

The FIG. 35 shows an alternative embodiment of the clamping 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 the pivoting of the lever 321 by tilting the two spring-mounted metal sheets 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 perspective cross-sectional view of FIG. 36 illustrates the structure of the tree stand 10, a series of struts between the outer housing flanks and the inner receiving portion 14 (see. FIGS. 1 to 4 ) having. These struts or stiffening ribs 125 serve to stabilize the structure and to support the forces acting on the holding elements 16 and their restraints (insert 34, receptacle 36) when clamping a tree. 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.

The FIG. 37 shows the tree stand 10 in a view from below with already mounted clamping device 32nd

Based on Figures 36 and 37 is again illustrated that the base area 12 of the tree stand 10 can be designed in an integrated design with the receiving area 14 and the receiving pockets 36 for 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. In the same way, the holding elements 16, ie, the gripping arms 18 and their inserts 34 can 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.

The FIGS. 38 to 41 show different embodiments of a centering system for the tree. The centering ring 52 accordingly Figure 38 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 have on their upper narrow sides in each case an inwardly inclined chamfer 523, which serves for better guidance of a tree to be used.

FIG. 39 shows a closed centering ring 54 having an inwardly inclined upper end face 541, which serves to guide the tree.

The centering 56 in accordance with FIGS. 40 and 41 also serves to center and guide 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 centering arrangements shown in accordance with FIGS. 38 to 41 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 presentation of the FIG. 1 illustrates the apparently within a closed ring (or more closed rings with multiple wrap) 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 can be made almost invisible. 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.

In a further preferred embodiment, the gripper arms 18 are each pivotally mounted in inserts 34, wherein the inserts in the vertical direction in receiving pockets 36 are inserted. Preferably, the inserts 34 are latched in the receiving pockets 36, in another preferred embodiment, the inserts 34 are glued or compressed in the receiving pockets 36.

The receiving pockets 36 are preferably arranged near the edge 141 of the receiving region 14. In a further preferred embodiment, the inserts 34 are made of plastic. In a further embodiment, the gripping arms 18 are each by means of an example in Fig. 5 prestressed torsion spring 38 shown.

Alternatively, it is also possible, such as in Fig. 10 shown to bias the gripping arms 18 by means of a tension spring 44 and / or a compression spring 45.

The inserts 34 and / or the gripping arms 18 preferably have mutually corresponding angle stops for limiting a pivot angle of the gripping arms.

Preferably, the inserts 34 and / or the gripper arms 18 each have a pinch protection. Particularly preferably, an anti-pinch protection is provided on the inner receptacle 14.

In a further preferred embodiment, the gripper arms 18 each have at least one tip 26 at a free upper end 24 for fixing the clamped object or tree. This is for example in Fig. 5 shown.

In a further preferred embodiment, the tensioning device 32 has a ratchet function with release device and in a further preferred embodiment, the tensioning device 32 has a foot lever 321, which is designed as a corner section of a polygonal base region 12. Furthermore, an overload protection is preferably provided for limiting a maximum tensile force acting on the pull cable 30.

Preferably, the stand is due to the rope guide to the top edge of the receiving area 14 filled with water and is made in a further preferred embodiment without a separate floor. Furthermore, the stand can be made without separate ballast be pressed on the stand, snapped, folded, bolted or welded.

In a further preferred embodiment, the cavities of the stator are filled with bulk material, preferably with bulk material of sand, gravel or granules. However, it is also possible to fill the cavities of the stand with water, mortar or liquid screed.

In a further preferred embodiment, stiffening ribs are cast with a potting compound and in a further preferred embodiment, the stiffening ribs are designed with ballast stones, wherein the ballast stones are particularly preferably glued to the stiffening ribs.

In a further embodiment (not shown), the traction cable is guided by more than 360 °. This means that the pull rope surrounds the tree to be held by more than a full turn. Thus, the rope can be guided partially overlapping within a holding element by suitable channels, so that in this way a loop or a loop is formed, with which the rope is guided in the corresponding holding element. By this embodiment, it is also possible to lead the rope in several turns, for example, three turns around the tree to be fastened. In this way, a significant increase in the massive holding power can be achieved.

Furthermore, it is by this embodiment, i. the multiple looping of the tree through the pull rope, it is possible to distribute the occurring forces over several wraps. As a result, the elastic elastic properties of plastic ropes (or similar elastic elements) can be used. The use of an elastic cable prestressing furthermore makes it possible to compensate for a tree shrinkage which occurs due to dehydration of the tree and in this way prevents the rope from having to be re-tensioned after some time of use. However, the use of stretchy ropes is also possible in the other embodiments described above and also when the rope is placed less than 360 ° around the tree. Depending on the material, these ropes to be used can be stretched by up to 100%, i. be biased.

In a further preferred embodiment, a two-level water level indicator is provided against flooding. In this embodiment, water is first filled, until the in the FIGS. 26-28 shown water level indicator 142, which is a float responds. In this case, the water itself is not visible from the outside. By further refilling with water, the upper flooding area is flooded and the water in the upper area becomes visible. This upper surface, which is set lower than the outer edge of the stand, can be completely flooded without water leaking out of the stand. In the known from the prior art systems, as soon as the water level is visible from the outside, already leaked water and therefore may already damage occurred by water, for example on parquet floors.

In the preferred embodiment, the stand can be kept watertight to the upper edge. In this case, this embodiment can be used independently of the respective cable tensioning system used and thus also in the known from the prior art tree stands. This upper flooding area is, for example, in FIG. 2 shown and provided with the reference numeral 148.

Figure 42 shows a side view of another embodiment of the stator according to the invention. It can be seen that a cable outlet 308 is increased and is arranged in this way above the upper edge of the stator. This increased cable outlet or cable exit channel can be used for all embodiments, ie both for those for whom the rope is laid more than 360 ° around the tree and for those cable systems where the rope is less than 360 ° around the tree is placed. Also for tree stand according to the prior art, the upper cable outlet can be used.

The upper rope exit, i. a rope outlet, which lies above the upper edge of the stand, has the advantage that in this way a complete filling of the stand with water has no influence on the cable outlet and thus no water can pass through the cable outlet.

The FIGS. 43 and 44 show further embodiments of a foot lever 321 for tensioning the hawser. This pedal also has a safety device or a safety lever 335, which can be moved between an open position 336 and a closed position 337. By using this safety lever, the Foot lever are locked in a predetermined clamping position and thus secured against accidental snap back and thus loosening the pull rope.

In FIG. 45 a further embodiment of a holding element for the stator according to the invention is shown. This retaining element additionally has retaining claws 162, which provide an even more secure hold for the tree held by these retaining claws 162. The retaining claws are provided at one end 26 of the retaining element 16.

At the in FIG. 46 shown embodiment of the holding element, a claw member 163 is provided, which has spikes or tips that.During the tensioning rope penetrate into the tree. The respective claws 162 or claw elements 163 can be used as independent elements in the holding element. Alternatively, however, it is also possible to integrate the claws or claw elements already during the production of the stator, for example by means of suitable injection molding or metal diecasting methods.
