  • the insert is made of one resistant material made and therefore very resistant to abrasion and is also with high forces resilient.
  • the insert is by means of a holding element attachable to the plastic light well, which Holding element at least part of the bearing section embraces.
  • the holding element and a leg of the L-shaped cross section are bracket-like trained so that the insert part easily on a part of the bearing section can be clamped.
  • the load is distributed through the insert, so that those acting on the storage section of the light well Surface pressures are relatively low.
  • the Plastic light well stiffened by the insert. With the insert part becomes a very resistant and durable support for the cover created. It will thus possible, the plastic light well essential easier to design and use a plastic that is inexpensive and easy to process.
  • the light well according to the invention also has the Advantage that the resulting final height of the cover is simple through the use of differently strong insert parts can vary. Frequently, for a specific Plastic light well, different covers offered that have different strengths, so that different final heights depending on the cover used reveal what is undesirable. This can be done with the light shaft according to the invention by different thickness Compensate insert parts.
  • the insert part is preferably made of a metallic Material made like steel.
  • Appropriate insert parts are simple and cheap to manufacture and very tough. To protect the insert against rust, it can be galvanized or made of stainless steel getting produced.
  • a section of the Insert part has an L-shaped cross section; so that not the entire insert must be L-shaped.
  • the L-shaped cross section also has the advantage that the height of the edge section simply by different Insert parts can be varied and therefore also to the used cover can be adjusted to a Flush cover and this bordering edge section to enable.
  • the insert part can have a holding element, which on a inner edge of the light well so that the Insert part is secured against displacement to the outside.
  • the insert part can also have a section which in an area of the bearing section, such as a hole or a Depression intervenes.
  • the insert can be constructed in several pieces or in one piece his. In order to achieve a secure covering of the cover, should the insert at least on two sides of the Cover may be provided. Of course you can too there are several insert parts on one side of the cover his.
  • insert parts can cover the scope be provided. But it can also be on two opposite An insert part can be provided on each side of the cover, that extends the entire length of the page. One or Several insert parts can also be provided so that the Full coverage on one or more Insert parts rests.
  • Figure 1 shows a first embodiment of a plastic light well according to the invention with cover in Cross-section.
  • Figure 2 shows a second embodiment of a plastic light well according to the invention with cover in Cross-section.
