Definitions

  • the invention relates to a plastic light well with cover according to the preamble of claim 1.
  • Plastic light wells are known in various designs and are usually covered by a cover to prevent objects from falling into the light well and to make the light well accessible if necessary.
  • the cover should be translucent. If the light well is to be covered so that it can be walked on, the cover must of course have a suitable load capacity. In most cases, steel grates or steel grids are used for walk-on covers.
  • Bearing sections correspondingly stable, i.e. be designed with correspondingly large wall thicknesses.
  • Bearing section occurs, which leads to abrasion of the plastic in the area of the bearing sections.
  • the plastic used and the construction of the bearing sections are therefore subject to a number of requirements.
  • the plastic or the bearing sections made of this plastic should withstand the pressure or surface pressure that occurs and the construction should be as rigid as possible and resistant to abrasion.
  • the plastic used should not be too hard, as otherwise particularly stressed sections can break out relatively easily and the risk of damage during transport or handling of the light well on the construction site increases.
  • the desired properties of the plastic should be maintained for as long a period as possible, since replacing the light wells is associated with high costs. Since light wells are mostly installed outdoors, the plastic must not become excessively brittle under the sun's rays and environmental influences. In addition, it should of course be possible to manufacture the plastic light well as cheaply as possible.
  • FIG. 5 shows a typical plastic light well according to the prior art.
  • This light well has a side wall 1, which is designed as a bearing section 2 in its upper region.
  • An outer part 5 of the cover 4 rests on the bearing section 2.
  • the cover 4 shown is formed by a grating which has on its circumference a sheet metal strip which is U-shaped in cross section and which represents the outer part 5 which rests on the bearing section 2.
  • an edge section 3 which still protrudes from the bearing section at a right angle is provided.
  • the object of the invention is to provide a plastic light well that is inexpensive to manufacture and is still suitable for high loads on the cover.
  • the object is achieved by the features of patent claim 1.
  • the plastic light well according to the invention can be covered with a cover which, however, is not received directly by a bearing section of the plastic light well, but by a special insert which is provided between the cover and the bearing section of the light well.
  • the insert is made of a resistant material and is therefore very resistant to abrasion and can also withstand high forces.
  • the absorbed load is distributed by the insert part, so that the surface pressures acting on the bearing section of the light well are relatively low.
  • the plastic light well is stiffened by the insert.
  • the insert part creates a very robust and long-lasting support for the cover. It is therefore possible to make the plastic light well much easier and to use a plastic that is inexpensive and easy to process.
  • the light well according to the invention also has the advantage that the resulting end height of the cover can be varied simply by using insert parts of different strengths. Different covers are often offered for a specific plastic light well, which have different thicknesses, so that depending on the cover used different end heights result, which is undesirable. In the light well according to the invention, this can be compensated for by insert parts of different thicknesses.
  • the insert part is preferably produced from a metallic material, such as steel.
  • a metallic material such as steel.
  • Appropriate insert parts are simple and cheap to manufacture and very resistant. To protect the insert against rust, it can be galvanized or made of stainless steel.
  • a design of the insert part with an L-shaped cross section has proven to be advantageous, with one leg being arranged between the cover and the bearing section. Since the cover that is put on must also be secured against slipping, conventional light wells have a circumferential edge section which projects at a right angle with respect to the bearing section and thus prevents the cover from slipping. Due to the L-shaped design of the insert part, this edge section can be omitted and its function can be taken over by the insert part, which further simplifies the construction and manufacture of the plastic light well.
  • a section of the insert part has an L-shaped cross section; so that the entire insert does not have to be L-shaped.
  • the L-shaped cross section also has the advantage that the height of the edge section can be easily varied by different insert parts and can therefore also be adapted to the cover used in order to enable the cover to be flush and the edge section enclosing it.
  • the insert part can advantageously be fastened to the plastic light well by means of a holding element, wherein the holding element can encompass at least part of the bearing section or can be connectable to the bearing section by means of a simple fastening means such as a screw.
  • the holding element and a leg of the L-shaped cross section is in the form of a clamp formed so that the insert part can be easily clamped onto part of the bearing section.
  • the insert part can have a holding element which rests on an inner edge of the light well, so that the insert part is secured against displacement outwards.
  • the insert part can also have a section which engages in an area of the bearing section, such as a hole or a depression.
  • the insert can be constructed in several pieces or in one piece.
  • the insert part should be provided on at least two sides of the cover.
  • insert parts can be provided over the circumference of the cover.
  • an insert part can also be provided on two opposite sides of the cover, which extends over the entire length of the side.
  • One or more insert parts can also be provided so that the cover rests over the entire circumference on one or more insert parts.
  • 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.
  • Figure 3 shows a third embodiment of a plastic light shaft according to the invention with cover in cross section.
  • Figure 4 shows a fourth embodiment of a plastic light barrier according to the invention with cover in cross section.
  • Figure 5 shows a plastic light well according to the prior art with cover in cross section.
  • Figure 1 shows a first embodiment of the invention.
  • a side wall 11 of the plastic light well merges into a bearing section 12 in its upper region, which is provided with a hole 18 approximately in the middle.
  • the cover 14 rests with its outer part 15 not directly on the bearing section 12, but on an insert part 16 which is provided between the bearing section 12 and the cover 14.
  • the insert part 16 has an essentially L-shaped cross section, a lying leg being arranged between the cover 14 and the bearing section 12 and the other leg being directed upwards and forming an edge section 13 which prevents the cover 14 from slipping and thus laterally specifies.
  • the illustration shown is a sketch in which only the most important features of the invention are shown schematically. In practice, the hole 18 will have a smaller diameter in order to keep the play of the insert part 16 small compared to the bearing section 12.
  • Figure 2 shows a further embodiment.
  • the side wall 21 merges into a bearing section 22, which is also provided with a hole 28.
  • the insert part 26 is screwed to the bearing section 22.
  • the exemplary embodiment shown in FIG. 2 can also be used with insert parts which, according to FIG Holding element can be positioned in the hole of the bearing section.
  • the insert part 26 is also provided with an L-shaped cross section, the lying leg, which is arranged between the cover 24 and the bearing section 22, at the same time being designed as a holding element 27.
  • the leg is provided with a conical bore in which the head of a countersunk screw 29 can be received flush.
  • the screw 29 is inserted through this hole and the hole 28 of the bearing section 22 and secured on the other side of the bearing section 22 by means of a nut 30. In this way, a firm and very reliable connection of the insert part 26 to the bearing section 22 of the plastic light well is achieved.
  • the L-shaped insert part 33 is provided on the leg arranged between the cover 34 and the bearing section 32 of the side wall 31 with a welded-on fixing pin 37 which engages in a hole 38 in the bearing section 32.
  • a wide variety of insert parts can therefore be used for these.
  • the insert part is fastened to the bearing section in the manner of a clip.
  • corresponding insert parts can also be used on bearing sections which are provided with a hole or a depression.
  • the insert part 46 of this exemplary embodiment consists of two parts which are connected to one another and each have an L-shaped cross section and are thus connected to one another are that the standing legs are in contact and the lying legs are at a certain distance from each other.
  • this insert 46 could also be formed in one piece.
  • the distance between the lying legs is dimensioned such that it is at least at one point smaller than the thickness of the bearing section 42.
  • the lower leg, which acts as a holding element 47, is provided with a downwardly bent end 50 in order to facilitate the insertion of the insert part 46 onto the bearing section 42.
  • the insert part 46 is simply plugged onto the bearing section 42 so that the lower leg lies below the bearing section 42, the upper leg lying above the bearing section 42 and thus being arranged between the latter and the bearing section 42 after the cover has been placed on it. In this way, the bearing portion 42 is protected from excessive stress by the cover 24.
