Definitions

  • the invention relates to a cover according to the preamble of claim 1.
  • Covers for a bottom-mountable open-topped hollow body e.g. a shaft or a drain body, in particular for a drainage channel
  • a bottom-mountable open-topped hollow body e.g. a shaft or a drain body, in particular for a drainage channel
  • Important in such covers is a secure hold of the cover against the hollow body, even if the cover is run over at a higher speed, which brings a pulse-shaped dynamic load with it. By such loads namely deform the covers and "jump" so to speak upwards.
  • loads namely deform the covers and "jump" so to speak upwards.
  • how laborious is the method of manufacture of the cover. Namely, such covers are installed in a wide variety, so that the manufacturing costs and also the installation costs are quite a noteworthy factor.
  • the previously known simple locking elements are often connected in a complex manner with side walls of the cover and formed as a resilient body which press against inner surfaces of the hollow body and engage in there provided recesses.
  • the known arrangements are too complicated to manufacture.
  • the invention is based on the object to develop a cover of the type mentioned in that in a simple manner a permanently functional safety, in particular a satisfactory contact pressure with little effort is achieved.
  • this object is achieved by a cover for a built-in a bottom, open-topped hollow body, namely a shaft or drain body, in particular for a drainage channel, comprising side walls on which locking elements are protruding from the side cheeks mounted such that the locking elements resiliently on inner surfaces of Hollow body can be pressed, achieved in that the side cheeks adjacent to the locking elements have spring portions such that the locking elements are easier to move toward each other than the side cheeks.
  • the locking elements are arranged between the upper edges and lower edges of the side cheeks, so stand out not further.
  • increased security against injury of the locking elements is guaranteed.
  • the lower edges of the side cheeks are smooth throughout.
  • the side cheeks are inventively designed to form the spring sections diluted. It can therefore be ensured by simply reducing the material thickness in sections, an increased spring action.
  • the side cheeks are designed to form the spring sections with wave-shaped sections. This results in areas which are variable in length, so that the adjacent, non-curved (and thicker) portions of the side cheeks do not have to yield when bending the locking elements.
  • the side cheeks are formed with the exception of the spring portions with a substantially constant thickness, so that a high stability can be ensured.
  • the cover is preferably formed from plastic, but in particular formed as an injection molded part. Thus, the cover can be produced in a simple manner.
  • a cover 10 is provided, the support edges 13, 14 which are connected by transverse webs 15 (with drainage slots lying therebetween).
  • Locking elements 30, 30 ' are provided, which either in recesses 3, 3' of the hollow body 1 advertise (see Fig. 1 ) or on inner surfaces 2, 2 'of the hollow body 1 (see Fig. 2 ) are pressed. These locking elements 30, 30 'each have a nose 33, which include a steep upper inclined surface 31 and a less steep lower inclined surface 32.
  • the locking elements 30, 30 'in the region of side cheeks 20, 20' are provided, the Go over the upper edges 23 in the support edges 13, 14. Bottom edges 24 of the side cheeks 20, 20 'are smooth continuous, formed substantially without protruding parts.
  • spring sections 21, 22 are provided in the side cheeks 20, 20'. These spring sections are formed in this embodiment of the invention as a simple material dilutions of the side cheeks 20, 20 'such that a waveform is formed.

Claims (4)

  1. Recouvrement pour un corps creux (10) intégrable dans un sol et ouvert vers le haut, à savoir pour un puits ou un corps d'évacuation, en particulier pour une rigole d'évacuation d'eaux, comprenant des parois latérales (20, 20') sur lesquelles des éléments de verrouillage (30, 30') sont montés en faisant saillie des parois latérales (20, 20') de telle sorte que les éléments de verrouillage (30, 30') sont susceptibles d'être pressés élastiquement contre des surfaces intérieures (2, 2') du corps creux (1) ou d'être pressés dans des évidements (3, 3') du corps creux (1),
    dans lequel
    les éléments de verrouillage (30, 30') sont agencés entre des bords supérieurs (23) et des bords inférieurs (24) des parois latérales (20, 20'), les parois latérales (20, 20') présentant des portions élastiques (21, 22) au voisinage des éléments de verrouillage (30, 30') de telle sorte que les éléments de verrouillage (30, 30') sont plus faciles à déplacer les uns vers les autres que ne le sont les parois latérales (20, 20'),
    les parois latérales (20, 20') sont réalisées amincies pour former les portions élastiques (21, 22) et présentent des portions incurvées en forme ondulée, et des portions voisines non incurvées des parois latérales (20, 20') sont réalisées plus épaisses que les portions élastiques (21, 22) et de manière à ne pas céder,
    caractérisé en ce que
    deux évidements de matériau en forme de portions cylindriques sont ménagés sur les faces extérieures des parois latérales (20, 20') et un évidement en forme de portion cylindrique est ménagé sur la face intérieure des parois latérales (20, 20') entre ces derniers, de sorte qu'en vue de dessus il en résulte une forme ondulée pour former les portions élastiques (21, 22).
  2. Recouvrement selon la revendication 1,
    caractérisé en ce que
    des bords inférieurs (24) des parois latérales (20, 20') sont réalisés lisses en continu.
  3. Recouvrement selon l'une des revendications précédentes,
    caractérisé en ce que
    les parois latérales (20, 20') sont réalisées avec une épaisseur constante, exception faite des portions élastiques (21, 22).
  4. Recouvrement selon l'une des revendications précédentes,
    caractérisé en ce que
    le recouvrement est moulé en matière plastique, en particulier sous forme de pièce coulée par injection.
