Abstract
Trench drains are hollow or grid-like bodies which can be installed in the ground and are intended to receive precipitated surface water and slowly dissipate it into the ground or to store the water. These hollow or grid-like bodies are constructed from individual drainage bodies which must be firmly connected together. Drainage body connecting elements are proposed for connecting drainage bodies, which comprise two pegs which are connected via a web and can each be inserted in a receiving orifice of a drainage body so the two drainage bodies can be connected together via the web.
Claims16
A drainage body system comprising:
- a plurality of drainage bodies, each drainage body including a plurality of receiving orifices;
- and
- a plurality of connecting elements each comprising:
- two pegs, each of the pegs having an opening at an upper end, and a lower end configured for insertion into a receiving orifice of one of the drainage bodies;
- a web connecting the two pegs;
- and
- a first locking device;
- wherein:
- insertion of each of the pegs of one of the connecting elements into the receiving orifices of a pair of the drainage bodies connects the pair of drainage bodies together, when the pair of drainage bodies are arranged side by side;
- the upper end of one of the pegs of a first of the connecting elements is configured to sit flush or countersunk to a surface of a first of the drainage bodies when inserted in a receiving orifice of the first drainage body, the pegs of a second of the connecting elements are configured to protrude above the surface when mounted on the first connecting element;
- the lower ends of the pegs of the second of the connecting elements are configured for insertion into the openings of the pegs of the first of the connecting elements, a peg of the second of the connecting elements being received in a receiving orifice of a third of the drainage bodies when arranged above the first of the drainage bodies to thereby connect the third of the drainage bodies to the first of the drainage bodies;
- the first locking device is a snap-lock locking device which locks each of the pegs of the connecting elements vertically in relation to the drainage bodies when inserted into the receiving orifices of a pair of drainage bodies;
- and
- the first locking device locks two connecting elements together vertically, when the pegs of one of the connecting elements are inserted into the openings of the pegs of the other connecting elements.

A drainage body system comprising:
- a plurality of drainage bodies including at least a first drainage body, a second drainage body, and a third drainage body, each drainage body including a receiving orifice;
- and
- a plurality of connecting elements including at least a first connecting element and a second connecting element, each connecting element comprising:
- two pegs, each of the pegs having a first end and a second end opposite the first end;
- and
- a web connecting the two pegs;
- wherein:
- the pegs of the first connecting element are inserted into the receiving orifices of the first and second drainage bodies thereby connecting the first and second drainage bodies together, when said first and second drainage bodies are arranged side by side;
- the first end of the peg of the first connecting element that is inserted into the receiving orifice of the first drainage body is flush or countersunk to a surface of the first drainage body;
- a slit connecting the receiving orifices of the first and second drainage bodies arranged side by side, the slit receiving the web connecting the pegs of the first connecting element;
- and
- a peg of the second connecting element is received in a peg of the first connecting element and the receiving orifice of the third drainage body, and protrudes above the surface of the first drainage body to thereby connect the first and third drainage bodies together, when the third drainage body is arranged above the first drainage body.
