Description

tree stand

The present invention relates to a tree stand, in particular a Christmas tree stand according to the preamble of claim 1.

A Christmas tree stand has become known, for example, from DE 39324-73 C2. It comprises a receptacle on which several lying in the circumferential direction are arranged each pivotable about a horizontal axis levers. The levers are over an encircling

Tensioning cable connected to each other, which leads to a tensioning device. By operating the tensioning device, the levers are moved about their respective horizontal axis to an inserted in the middle trunk of a tree, the levers are arranged and aligned so that the levers are each moved more or less on the vertical axis of symmetry of a tribe to be adjusted.

A corresponding Christmas tree stand is also from the DE 202 18 172 Ul became known. It comprises a housing cover and a housing bottom with a seam, which are connected together inextricably by welding. As a result, the chamber should be sealed in liquid-tight manner against the areas of the stator adjacent to it in order to create a large space for receiving water. This is intended to ensure freshness, for example, of a Christmas tree used in the stand and to be fixed over as long a period as possible.

Another stand for vertical fixation rod-shaped objects has become known with DE 38 24 675 Al. It comprises a cup-shaped foot part with a positive lid part with a plurality of through openings around an eccentrically arranged passage opening around, which is designed as a guide bearing for a setting, which is placed on the stump of the Einstellgutes, such as a Christmas tree. This embodiment requires a precise adjustment of the Einstellgutes to the adjusting.

There are also Christmas tree stands are known that dispense with techniques such as cable with ratchet, with a setting around which a plurality of wing screws with normal pitch are arranged. If anything, these types of stands have only small irrigation devices or are designed to be used in separate vessels that have a small footprint and therefore can only securely fix trees of limited height.

A disadvantage of all known so-called Functional tree stands is, however, that the assembly work of the entire Christmas tree stand including the assembly of the holding device with the associated pivot axes, clamping device ect. quite labor-and thus time-consuming and expensive.

The conventional stands have to provide the tree trunk sufficient stability, a relatively high construction and thereby cause high transport costs.

Object of the present invention is to provide a so far improved tree stand, especially Christmas tree stand, which has a simple structure, which optimally accommodates the appropriate holding and clamping forces despite simple design and while doing a large receptacle for holding water to keep fresh a to be fixed Tree has.

The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

The present invention provides a significant improvement over conventional solutions in a surprisingly simple manner.

The Christmas tree stand according to the invention preferably comprises a circular shell with a peripheral mortar arranged on the upper edge, which on the one hand serves for the dimensional stability of the shell and on the other hand allows the attachment of a plurality of stand feet arranged at a distance from one another. In the central interior The shell is preferably a cylindrical container having an insertion opening provided in a first embodiment in its upper edge region a plurality of approximately equally spaced through threads for receiving threaded bolts at the outwardly facing ends each have a gag attached oa and pointing to the central axis ends with a circumferential notch or a groove are provided.

On the one hand to ensure high stability of the tree by as far as possible on the stump lying attack zone of the holding elements, and on the other hand to achieve the lowest possible design of the stand because of transport costs, easily releasable holding elements can be provided, which protrude into the stand, this project ,

Within the cylindrical container, in the vertical axis, below the through threads, are provided as close to the bottom, preferably on its inner wall, cams, which can accommodate a holding element in a vertical position together with the notches on the threaded bolt. The holding elements are in its axis preferably provided with a slot or a plurality of slots so that they engage behind the cams and engage in the notches on the threaded bolt and thereby causes, when screwing the threaded bolt in the passage provided therefor, the holding elements with their remain pointing towards the bottom ends approximately in the region of the outer wall of the Einstellbehälters, while the investment areas are pressed to the central axis, ie to the parent plant, out. The cylindrical container should have a plurality of passage openings for the purpose of fluid exchange to the shell out and on the ground is provided for fixing the trunk one or more mandrels.

According to the invention, it is provided that the passages in the edge of the adjusting container preferably have no thread, so that instead of threaded bolts preferably thrust bolts are provided with spaced circumferential Aufwerfungen (ribs, springs, etc.) to form grooves therebetween, preferably at their outward pointing ends serve guides for receiving a preferably guided around the Einstellbehälter around tension spring. The retaining elements may be provided with vertically extending slots for the purpose of rapid assembly or removal, but extended beyond their abutment region, wherein the extensions may be bent outwards (towards the edge of the frame) at an approximately 70 ° angle.

The prestressed spring pushes the thrust bolts through the through holes provided in the adjusting container and with them releasably coupled to them holding elements towards the central axis, resulting in a now within the obliquely upwardly and outwardly facing ends of the holding elements.

Now, if the tree stump is set in the funnel-shaped opening, the tree stump, driven by the dead weight of the tree, slides along the inner sides of the holding elements, pushes them and the coupled with them thrust bolts against the spring tension gradually from its rest position to its final Stand on the fixing pin, which penetrates completely or partially into the underside of the tree stump. The stump is now fixed on its underside and prefixed in the area of the holding element system, whereby an alignment of the tree is possible.

For the final fixation of the tree stump on the holding elements and the thrust bolts coupled with them, a fixing ring is provided, which preferably comprises the upper edge of the Einstellbehälters and in the region of the passage openings preferably horizontally extending slots, which can be brought in an overlapping position to the passage openings on the adjustment , Here, the thrust bolts can pass through the openings in the fixing and / or locking ring so that the congruent passage openings in the adjustment. By turning the fixing and / or locking ring then ultimately the thrust bolts can be jammed so that they no longer release a jammed stump. Preference is given to this in the fixing and / or locking ring extending in the circumferential direction, tapering in the closing direction slit-shaped passage opening introduced, the edge can then engage in the groove-shaped recesses between two bulges in the thrust bolt, whereby the thrust pin against an expulsion of a tree trunk to be fixed is secured away. It is also possible jamming of the thrust bolt in such a way that the bulges and the grooves located therebetween with edges or edges in the region of the passage openings on the adjusting container tilt etc. Any deviations are possible here. As has already been mentioned above in connection with a preferred embodiment, when the fixing ring is rotated around the setting container, the limitation of the tapering slots between the bulges (ie the projections, ribs, webs, springs, etc.) is forced in, in other words, the edge of the tapered slots moves in the grooves between the bulges, whereby the thrust bolts are fixed in position.

According to one embodiment of the invention, several feet are provided for particular stability of the stand, which are preferably each equally spaced on the outside, from the stand pointing away, for which a circumferential cranked edge on the stand shell particularly suitable that an incision in the stand base , is pushed from the top down from the bottom of the bent edge.

The preferably releasably arranged feet can be designed in various designs. The simplest embodiment is a flat, preferably made of plastic base. In order to achieve a greater balance weight, hollow, be filled with Beschwerniesmaterialien, such as sand or water feet can be provided.

According to a further exemplary embodiment, recesses can be used on the preferred lower sides of the feet for accommodating rechargeable batteries for the power supply of LED luminaires or lighting fixtures in the peripheral edge of the stator shell. Another execution Example, which could serve the increased stability, is an additional container that can be partially filled with Beschwernismaterialien, or itself is made of a material with high weight, has a wide smooth bottom and applied with its edge the cranked edge of the stator shell.

Due to the simple final assembly of the bulky elements, such as holding elements and feet by the consumer, also a considerably smaller packaging size is preferably achieved, thereby significantly lower storage and transport costs are achieved. Another saving results from the fact that the entire stand, apart from the spring accumulator, can be made of plastic.

In FIGS. 1 to 3, a basic structure of a stator is shown, which already includes preferred variants of the invention with regard to some features, the embodiment of the stator according to the invention being explained in more detail with reference to the further examples according to FIG. FIG. 1 shows a stator shell 1 which is open towards the top and has an adjustment element arranged inside the stator shell 1. container 2, which is arranged approximately centrally and upwardly open or better formed, and from which the several, approximately equally spaced and preferably releasably arranged holding elements 3, 3 a, 3 b, are provided, which by means of their respective associated screws 4, 4a, 4b are pressed into the holding position by screwing into the threaded bores 5, 5a provided for this in the adjusting container, towards the central axis. Furthermore, two different feet 6, 7 are shown in the embodiment. The base 6 may be hollow and fillable with complaining materials (such as water or sand). The base 7 is simple and flat. For stable attachment of the feet 6, 7 slots 8 are provided in the feet 6, 7, which include the cranked, downwardly facing edge 9 of the stator shell 1. In order to restrict their freedom of movement towards the sides, stiffening walls 10, 10a are provided, which are mounted inside the cranked edge 9. In addition, the cranked edge 9 of the stator shell is ideal for accommodating lighting fixtures such as LED lamps eleventh

Figure 2 shows in section mainly the operation of the easily and quickly used and again removable designed retaining elements 3, 3a, 3b, which are inserted by means of a slot 12 in its vertical axis first in a groove on the screws 4, 4a, 4b and with their after bottom facing end behind cam 13 or preferably connected to the bottom of the stator shell 1 associated pockets 14 for pivotal mounting. For the purpose of water exchange between the stator shell 1 and the setting container 2 through holes 15 are provided. To increase the stability, without the use of feet 6, 7, an upwardly open shell 16 according to FIG. 3 can be used, which either brings itself a high own weight or is partially filled with complaint materials and with its upper peripheral edge into the cranked one Edge 9 of the stator shell 1 is releasably placed under it releasably.

FIG. 4 shows an inventive development of the tree stand shown in FIG. 1, which differs from the previously described embodiment by further features. The tree stand according to the invention comprises a foot part 1, which is also referred to below as a stand shell 1 due to its design. This foot part or this stator shell 1 have in the central central region on a receiving space Ia, in which the other means for fixing a tree trunk are provided. The holding elements 17, 17a, 17b are bent outwardly above their intended area for the main area approximately at a 70 ° angle, so that results in their rest position, near the central axis, a Einstelltrichter. As described in connection with Figure 2, the plurality, preferably three, four or more approximately equally spaced support members 17, 17a, 17b with its approximately extending in the vertical axis slot 12 in designated grooves 19 are pushed to shear pin 18 to them then with their downwardly facing ends behind preferably cam 13 comprehensive stops pivotally mounted. An essential component of this embodiment are the thrust bolts 18, 18a, 18b, which are movable in thrust-through openings 20 in the edge region of the Einstellbehälters 2 are mounted and starting from their facing the central axis ends, a groove 19, according to Figures 5 and 6, a plurality of circumferentially spaced apart rings 21 and at their protruding from the Einstellbehälter 2 ends for guiding a spring memory 23 suitable receptacle 22.

Since the adjustment container 2 can have any shape, that is to say can consist of any desired construction, so far in the following, at least in part, is also spoken by a setting support device 2.

The aforementioned holding elements 17, 17 a, 17 b can also be fastened or formed in a fixed and non-detachable manner at a suitable location in the inside of the stator shell 1. Basically, even the use of holding elements would be possible, which are connected to the thrust pins 18, 18a and 18b and acted upon by these, in order to pressurize a tree trunk to be used in the center under pressure. In extreme cases, even the inwardly projecting end-side end of the bolt can serve as retaining elements 17, 17a, 17b, which rest in the outer circumference of a tree trunk to be fixed and are pressed into it.

The holding elements shown with their funnel-shaped training upwards but offer improved comfort during insertion of a tree trunk to be fixed, as will be described below. The mentioned opening angle of 70 ° is mentioned only as an example. Any angle is suitable that facilitates the insertion of a tree trunk. Therefore, the angles can be up to 80 ° or 85 °, forming a relative narrow, pointed funnel or else be even smaller, for example, be 65 ° or 60 °.

When inserting a tree stump in the funnel-shaped opening of the holding elements 17, 17a, 17b they are pushed through the stump end and the weight of the tree to the outside (ie away from the central axis), whereby the coupled with them thrust bolts 18, 18a, 18b against the Spring tension of the guided them spring accumulator 23 are moved. As a result of this and by placing the tree stump on a centering mandrel 24, the tree is prefixed and can be aligned in its final position. For steady fixation of the tree is a fixing ring 25, as shown in FIG 7, which is attached peripherally at the top of the Einstellbehälters 2, the slot in the number of thrust bolts 18, 18 a, 18 b, tapering towards a common side, the thrust pin 18th , 18a, 18b has comprehensive passages 26, 26a, 26b and a movement handle 27. If now the fixing ring 25 is moved around the central axis, the tapered passage openings 26, 26a, 26b (ie the edge 126 or certain portions of the edge 126 of the tapered passage opening) engage in the space between two rings 21 on the push pins 18, 18a, 18b, block them and with them the coupled to them holding elements 17, 17a, 17b. The slot-like through holes 26, 26a, 26b are thus divided into a tapered portion 26 'and an enlarged portion 26 ".

It can also be seen from the drawings and the described structure that the slot-shaped passage openings 26, 26a, 26b do not have to be primarily tapered in order to prevent the Fix bolt 18. For these passage openings 26, 26a, 26b in the fixing and / or locking ring 25 are at least partially congruent with the passage openings 20 in the edge region of the Einstellbehälters 2, wherein the slot-shaped passage openings 26, 26a, 26b only have to be formed and / or arranged in that the overlapping or overlapping portion of the respective through-opening 26 with the container opening 20 becomes smaller in cross-section such that, for example, an edge portion 126 of the slot-shaped through-openings 26, 26a or 26b between two spaced elevations 21 (bulges 21), ie in one therebetween lying groove 28 engages, whereby the thrust bolts 18, 18a, 18b are blocked against axial displacement and locked.

FIG. 6 shows a particularly advantageous arrangement of the spaced-apart rings 21 or of the grooves 28 on the push pins 18, 18 a, 18 b. Due to the inclination of the rings 21 (ie the protruding bulges, rib-like or spring-like projections, etc.) or the corresponding inclined position of the grooves 28, the thrust pins 18, 18 a, 18 b and with them the attached holding elements 17, 17 a, 17 b not only blocked, but urged by the angle of inclination of the fixing ring 25 to the central axis, ie Thus, in addition to the central axis, additional force is applied, whereby a tree stump is held even better and fixed.

The above-mentioned bulges 21, which are sometimes referred to as rings 21, so represent projections 21 or elevations 21, for example, as web, rib, tooth or annular elevations 21 can be designated, which are provided at a distance from each other several times, and between each of which a deeper groove 28 is formed. This results in a rack-like, rib-like or thread-like structure with successive elevations 21 and groove-shaped depressions 28. These are provided in the longitudinal direction of the push pin 18 offset from each other or formed on this and as mentioned preferred to a vertical plane with respect to the longitudinal axis of the bolt and Thus, the longitudinal adjustability of the bolts 18, 18 a, 18 b slightly angled (obliquely) aligned, so that in conjunction with the fixing axial thrust movement in the direction of the tree stump to be fixed, ie at least approximately in the direction of the central and not shown in detail central or vertical axis when adjusting the fixing in fixation takes place. The central or vertical axis rises through the centering pin 24 (perpendicular to the bottom surface) of the stator shell 1 extending.

In principle, the thrust bolts 18, 18a, 18b can be designed as desired. Optionally, even as mentioned, the use of bolts is suitable because they have thread-projecting teeth, springs and the like which may be referred to as spaced arches or spaced projections 21 between which are formed grooves into which an edge 126 is formed an overall tapered passage opening between two such tooth-shaped or spring-shaped bulges formed groove can intervene.

FIG. 8 shows a conventional and normal stand base 6 shown how it can be used in connection with the tree stand according to the invention.

9 shows an embodiment of a stand base 6a, the cavity of which can not only be filled with distress materials, such as sand or water, but can receive an energy store 30 by means of a recess 29, preferably on the underside.

A modification is shown with reference to FIG. 10 in that here the sliding ring 25 can not be adjusted as in FIG. 7 with a manually operable handle 27 (ie in a direction of rotation in the blocking direction and in the opposite release direction running around the central axis), but a rotary lever device 127 having. For this purpose, the fixing and locking ring 25 in a peripheral portion 128 a tooth engagement 129, in which a gear 130 engages. The gear 130 is seated on a shaft 131 which is supported in a corresponding, not shown in detail bore or a journal bearing in the Einstellbehälter 2 (ie in the Einstelltrageinrichtung 2) and beyond in a guide 132 at least indirectly on the stator shell 1, here at the top Edge 1 'of the stator shell. About an outer rotary handle 135 can be adjusted by turning the fixing and locking ring either in the fixing direction or in the opposite release direction.

The fixing and locking ring 25 does not need separate guide means to be held on the outer circumference of the Einstell- container 2. Because by the push pins 18, which pass through the corresponding openings in the fixing ring and in the upper edge region of the Einstellbehälters 2, it is ensured that the fixing and locking ring 25 does not fall down or can be pulled off to the top. Incidentally, it is noted here that a corresponding fixing ring, in principle, if corresponding provisions for adjusting are concerned, can also be arranged inside the setting container 2, with otherwise identical or comparable functioning.

Slight modifications are shown with reference to FIGS. 11 to 13:

In the variant according to FIG. 11, the tooth engagement 128 is designed as a separate component 128a, which is fastened on the fixing and locking ring 25.

In the variant according to FIG. 12, an eccentric 137 has been used, which engages in a corresponding eccentric recess 139 on the edge of the fixing and locking ring. By rotating the rotary lever 135 of the eccentric or the nose 137 is pivoted depending on the direction of rotation to the left or right, which is rotated by the driving engagement between the eccentric 137 and recess 139 of the fixing ring to the left or right to release the bolt for adjustment or to lock.

The variant according to FIG. 13 shows only a slight modification, in which not a downwardly free recess 139, but a hole recess 139 'is shown, with a corresponding extension into which in turn the eccentric 137 or the nose 137 engages, in order to effect the rotational movement for the fixing and / or locking sleeve 25 perform. Reference will next be made to a modification according to FIGS. 14 to 17, in which slightly modified thrust bolts 18 are used.

In this exemplary embodiment, on the one hand, the passage openings 20 in the upper edge region of the adjustment container 2, ie in the upper edge region of the adjustment support 2, are dimensioned significantly larger than the cross-sectional dimension of a push bolt 18 engaging here. Likewise, the slot-shaped or slot-like passage opening 26 in the fixing and / or locking ring 25 at least in the release position larger dimensions than the cross section of the thrust bolt 18, which in this embodiment has a rectangular or square cross-section and only two opposite, here on the upper and lower side 118a, 118b, with the corresponding rib-like projections , Bulges 21, so elevations 21 and the grooves 28 formed therebetween is provided. In FIG. 14, the starting situation is shown in a schematic, partial vertical sectional view, in which a corresponding push bolt engages in a corresponding rearward groove only by an outer spring force storage device (not shown in FIG. 4), and the push bolt otherwise pressurized only inwardly under the force of the spring accumulator 23 in the direction of the central axis, so that therefore the retaining elements 17 pivot inward. The fixing and locking ring 25 is thus in the representation of Figure 14 in its release position, in which the push pin 18 in the representation of Figure 15 in the left side of the slot-like passage opening 26 extends through, here So game up and down to the edges 126 has. In this situation, now a tree stump can be used, which runs on the oblique, upwardly funnel-shaped extended portions of the holding lever, the holding lever shown are now pivoted outwardly, the pintle 18 are also pivoted outwards, against the force of Spring accumulator, which is not shown in Figure 14, but is shown in Figure 4. Then the inserted tree stump can then be firmly fixed.

For this purpose, the aforementioned adjusting ring 25 is rotated in the closed position, wherein the push pin 18 is moved from its release position according to Figure 14 in its blocking position shown in FIG 17. In this position, the rear end of the thrust pin 18 comes to rest in the slot-like through hole 26 in the narrower from its height, ie smaller dimensioned portions 26 '. Due to the curved shape of the lower edge 26 'of the slot-like design of the through hole 26 so the rear end of the thrust bolt 18 is raised and by the interaction with the edges of the passage opening 20 - as shown in Figure 17 - slightly inclined, so that the respective thrust pin 18, for example, by an upper edge 102a and a lower edge 102b once more lying outside, once more lying inside, on a reinforced portion 102c of the one te 11 t rageinrichtung 2 (ie the Einstellbehälters 2) is tilted, which he does not can be further adjusted to the outside.

By the tilting movement generated during the locking process when turning the fixing and locking ring 25 the respective thrust pin 25 whose acting on the holding elements 17 leading end is pivoted downwards, where the holding elements are aligned obliquely outward to its underlying fixing position (anchoring), whereby an additional small pivotal movement and pivoting force exerted on the retaining lever 17 in the direction of the central axis becomes. This leads to a force increasing fixation of a tree trunk, when the fixing ring is adjusted in the closed position.

With reference to the figures 18 to 20 is shown only schematically that the feet 6, 7 can also consist of pivoting feet, which are pivotable about a preferred vertical axis 106 between a restricted transport position and a radially outwardly pivoted functional position. In this case, the respective pivot lever in the adjacent region to its pivot axis 106, for example, with a first and second preferably straight or flat Anschlagskante- or surface 107, 108 may be provided. These abutment surfaces 107, 108 can each interact with an elastically deformable fixing stop 110, which is formed, for example, elastically deformable on the stator shell 1. When pivoting from the retracted to the extended position of the foot or vice versa, as shown in Figure 17, thereby by the radially extending from the axis 106 further transition or corner region 111 between the two mutually perpendicular stop surfaces 107, 108 of the Fixieranschlags 110th pivoted slightly outwards, wherein the fixing stop abuts again on the respectively other abutment surface 107, 108 when the foot has its radially outwardly extending functional surface. Position or its folded by 90 ° transport position has reached.
