The invention relates to a push-in mandrel for anchoring artificial flowers in wreaths, containers or the like, which has barbs that increase static friction.

In a known embodiment, the approaches of the pressing mandrel are sawtooth-like, d. H. the approaches are relatively small, so that they only give insufficient anchoring. if such a trained mandrel z. B. is pressed into a wreath of forest, can be the so attached Pull the flower out of it again without great effort; often the flowers also fall Transport of the wreath out of this again. Another disadvantage is that the Twist flowers slightly, which will lose their good looks. These deficiencies occur especially Strong when the flowers are in relatively weak or not very deep wreaths or bundles can be plugged in, regardless of whether they are with or without a substructure made of straw or foamed plastic exist. For this reason, wires have so far been used predominantly, i. i.e., the respective flowers are attached Pieces of wire or are provided with pieces of wire that pierced through the wreath or the container and bent at the free end. However, this type of anchoring is not appropriate since the user often injures his fingers when bending the usually pointed wires, quite apart from the fact that the processing of such is very time consuming and therefore high Labor costs lead to increases.

Furthermore, so-called moss-like are known, which consist of U-shaped wire brackets with equal or unequal exist long legs, which in turn have the static friction increasing barbs. These barbs but are, similar to the previously mentioned sawtooth-like approaches, relatively small, see above that their adhesive effect is not sufficient. In contrast, the mandrel according to the invention is without Difficulties, i.e. without any significant expenditure of time in wreaths, containers or the like, with and without The substructure can be pressed in and gives the material to be attached a secure hold.

This object is achieved according to the invention in that the barbs are finger-like and are arranged opposite to the direction of depression at an acute angle on the mandrel, the mandrel integrally or detachably into the flower or the like to be anchored. A mandrel designed in this way can be inserted easily and in a very short time without falling out of the mounting base, since the barbs can be pushed in for anchoring when a load is applied

of the dome against the direction of insertion spread further and further apart and thus become larger and larger find future abutments. The protruding barbs also provide an excellent anti-rotation device given so that the new mandrel meets the requirements of practice both in mechanical and

ao is fair in terms of taste. The production Such a dome with barbs is by no means expensive, since it can be easily made in one piece made of plastic, it does not matter whether the tip of the mandrel is in the Flower or the like penetrates or not. By appropriate selection of the plastic, the Conveniently affect the elasticity of the barbs.

According to a further feature of the invention, they are preferably made of plastic in one piece with the dome manufactured finger-like attachments arranged in pairs in a plane lying in the axis of the mandrel, in the case of two or more pairs, these can lie in planes at different angles. Usually you can one pair or two pairs in a single level are considered sufficient, whatever is favorable in terms of tool technology, since a two-part shape without undercuts is sufficient. With waiver Anchoring security can be added to this convenience by angular displacement of the barbs increase even further. With further abandonment of simple tools, it is according to the invention also conceivable that the barbs made in one piece with the mandrel evenly on the circumference to distribute the cathedral, so z. B. three pieces at different heights.

In the case of an arrangement of two or more pairs or in the case of triple arrangements or the like, the length the finger-like barbs may be different, which in turn improves the anchorage can be achieved in the various substructures of wreaths and containers. Also is it is useful if the barbs are at their free

In addition, the barbs 9 also the advantage that the device as such is sharpened, which also applies to FIGS. 2 and 3, Economical in large numbers and given.
