Definitions

  • the invention relates to a plastic cone with a porous and / or cellular nucleus, which is of a tough and hard Coat is enclosed, the cone with one of its Footprint forming, opposite the mantle of the Provide cone with different base material which is perforated in the middle and one with a perforated edge has outgoing sleeve, which is in the core of the Cone stretches.
  • Plastic cones for bowling alleys in the sense of this application also include so-called bowling pins.
  • the invention has for its object a good or an improved connection between the floor on the one hand and the overlying part of the cone shell on the other hand.
  • the Sleeves with advantage circumferential ribs preferably have a sawtooth-like cross section.
  • This anchoring can be done easily due to the invention will be realized. That is because the inside of the cone protruding sleeve with said projections is provided and the cellular and / or porous Plastic core forming material at the Cone production from below through the sleeve in the Cone cavity inserted, so the material penetrates down to the inside of the floor in front, where the material encloses the sleeve on all sides while doing so the form closure. To the material flow not to bother, it is advantageous to cover the floor with a or several fine ventilation holes.
  • the cone has one in the usual way in the foot area Bottom 1, above a belly 2 that narrowed into one Neck 3 merges, and a head 4, which compared to the Belly 2 has a smaller outside diameter.
  • the Components 2, 3 and 4 form the jacket 5 of the cone.
  • the cone also preferably has an outside adhered core 6, which consists of a cellular and / or porous plastic and by inserting a expand material after completion of the Outer shell (bottom 1 and jacket 5) inside this envelope through the central hole 7 in the bottom 1 in the inside is initiated.
  • the bottom 1 is made of a mostly harder plastic based on polyamide manufactured. Although these materials are suitable, go however not always a sufficiently strong bond with each other.
  • the core 6 Material As already mentioned, it becomes the core 6 Material is introduced, it not only gets into the Belly 2, neck 3 and head 4, but also in the sense the arrows 10 in the area of the bottom 1, the trapped air through small holes 11 in the bottom 1 can drain off.
  • the sleeve 8 is enclosed the solidification and stiffening of the core material there is a positive connection between the core 6 and the Sleeve 8 or the bottom 1. This means that the bottom 1 is firmly connected to the jacket 5.
  • the bottom 1 has an upward widening sleeve 8, so the outside essentially conical sleeve 8 on (D greater than d), which also results in a form fit Forms an undercut for the core material.
  • Projections 9 may also pimples or warts or projections that are only part of the Extend sleeve circumference. But it is tick-like in any case, for sufficiently large undercuts to care. That is why saw teeth are very appropriate. Also can be a different instead of the hook connection executed tongue and groove connection.
