DESCRIPTION:
BRIEF SUMMARY
The invention relates to a stand for securing Christmas trees and similar objects, e.g. sunshades, fence posts, flagpoles, partitions and the like, it being the intention for said objects to be centered in a clamping-type mount of this stand.
A stand of this type has been disclosed, for example, by the subject matter of German Utility Model 94 03 811.
By way of this known arrangement, a description is given of a Christmas-tree stand on whose cross-shaped foot there are arranged inwardly directed resilient elements whose radially inwardly bent ends are bent radially outward again in the form of an arc, so as to provide a clamping-type mount for an approximately cylindrical object, it being the case that said resilient elements are positioned, against said object which is to be retained, merely by spring force and frictional locking, but without wedging into the object.
This has the disadvantage that said springs are only positioned by friction locking against the outer circumference of the object which is to be retained, e.g. the Christmas-tree trunk, which results in the latter being unstable.
Moreover, it is not possible to compensate for a crooked trunk by introducing the latter obliquely into the retaining means, because the resilient elements always act on the outer circumference of the trunk with the same spring force from all sides.
Moreover, it is further disadvantageous that the resilient elements are positioned against the trunk in a frictionally locking manner relatively close to the ground, and this gives a poor retaining action. The actual retaining action is effected, for the most part, by a relatively large, approximately star-shaped resilient element which, at the same time, forms the cross-shaped foot and a top, narrowed section into which it is intended to introduce the trunk which is to be retained.
In addition to the high outlay in terms of materials, and the associated high production costs, this solution has the disadvantage that the trunk, in turn, is only retained in a frictionally locking manner by the top, central resilient element, which forms the cross-shaped foot, and, in turn, said resilient element merely butts against the trunk in a frictionally locking manner.
This means, however, that the stability of the entire trunk in this stand is brought into question.
The object of the invention is further to develop a stand of the type mentioned in the introduction such that, along with considerably lower production outlay, more stable fastening of the object is ensured.
In order to achieve the set object, the invention is defined by the technical teaching of claim 1.
The essential feature of the invention is that one or more mutually opposite resilient elements are provided on the inner circumference of the retaining element, each resilient element comprising a resilient clasp which is fastened on the inner circumference of the retaining element so as to run obliquely downwards and, at its respective end, has one or more tips, it being the case that at least the tips are directed radially inwards.
The given technical teaching gives rise to the considerable advantage that, upon introduction of an object which is to be retained, preferably a Christmas-tree trunk or another type of object which is to be retained, the tips of the resilient elements dig into the object, preferably into the trunk, and this results in the tips being locked in the object with a positive and frictional fit, so that it is no longer possible for the latter to be released from the stand without outside intervention.
For the sake of simplicity, the following description will take as its departure point the task of securing a Christmas tree in a Christmas-tree stand, but the invention is not restricted to this, as has been emphasized a number of times above.
If, therefore, a Christmas tree is introduced into the retaining means from above, then the introduction operation takes place in a particularly straightforward manner because a wide variety of diameters can be introduced into the stand, ensuring great variab
