Drain trench body and center plate
View Patent ↗The invention relates to a drain trench body having base plates ( 11, 12 ), between which columns ( 13 ) are arranged vertically. The drain trench body comprises side walls ( 14 ) which are connected to the base plates ( 11, 12 ). The side walls ( 14 ) and the base plates ( 11, 12 ) have first and second locking elements ( 15, 16 ) which are in engagement with each other. The locking elements ( 15, 16 ) are movable relative to one another in the height direction along the longitudinal axis of the columns ( 13 ). The invention further relates to a center plate ( 20 ) for a drain trench body.
1. A drain trench body comprising base plates ( 11 , 12 ) between columns ( 13 ) that are vertically arranged, and side walls ( 14 ) to which the base plates ( 11 , 12 ) are connected,
the side walls ( 14 ) and the base plates ( 11 , 12 ) comprise first and second locking elements ( 15 , 16 ) which are engaged with one another and can move relative to each other in the direction of height along the longitudinal axis of the columns ( 13 )
wherein the base plates ( 11 , 12 ) comprise outer surfaces ( 17 ) which extend in the direction of height, and the side walls ( 14 ) rest on the outer surfaces ( 17 ) and can move relative to the outer surfaces ( 17 ),
wherein the outer surfaces ( 17 ) comprise edges ( 18 ) and the side walls ( 14 ) comprise projections ( 19 ) which extend inward and cooperate with the edges ( 18 ) as stops for limiting the relative motion of the side walls ( 14 ) in the direction of height.
2. The drain trench body of claim 1 , wherein the first locking elements ( 15 ) are designed as catch elements of the side walls ( 14 ), and the second locking elements ( 16 ) are designed as holding edges of the base plates ( 11 , 12 ) that extend in the direction of the height.
3. The drain trench body of claim 1 , wherein at least one center plate ( 20 ) is arranged parallel to the base plates ( 11 , 12 ) between the columns ( 13 ).
4. The drain trench body of claim 3 , wherein the center plate ( 20 ) rests on at least one of the side walls ( 14 ).
5. The drain trench body of claim 3 , wherein the side walls ( 14 ) and the center plate ( 20 ) comprise third and fourth locking elements ( 21 , 22 ) which engage with each other and can move relative to each other along the longitudinal axis of the columns ( 13 ) in the direction of height.
6. The drain trench body of claim 5 , wherein at least one of the side walls ( 14 ) can be divided along a virtual dividing plane running parallel to the base plates ( 11 , 12 ).
7. The drain trench body of claim 6 , wherein the third locking elements ( 21 ) of the side walls ( 14 ) are arranged on both sides of the dividing plane running parallel to the base plates ( 11 , 12 ).
8. The drain trench body of claim 7 , wherein the side walls ( 14 ) and the base plates ( 11 , 12 ) or the central plate ( 20 ) are produced from different materials.
9. A center plate ( 20 ) with at least one base plate ( 11 , 12 ) connected to vertically arranged columns ( 13 ) and side walls ( 14 ), wherein the center plate ( 20 ) comprises recesses for the columns ( 13 ) for arranging the center plate ( 20 ) parallel to the at least one base plate ( 11 , 12 ), and locking elements ( 22 ) configured to engage with corresponding flexible locking elements ( 21 ) of the side walls ( 14 )
wherein the locking elements ( 21 ) are projections on the side walls, and the locking elements ( 22 ) are designed as holding edges of the center plate ( 20 ) that extend in the direction of the height.
10. The center plate ( 20 ) of claim 9 , wherein the locking elements ( 21 , 22 ) are engaged with one another and can move relative to each other in the direction of height along the longitudinal axis of the columns ( 13 ).
11. The center plate ( 20 ) of claim 9 , wherein each locking element ( 22 ) engages with two locking elements ( 21 ) disposed on opposing edges of the locking element ( 22 ).
