Drainage channel with a drainage body and a cover

Abstract

A stable and variable design of a drainage structure includes a drainage body (11) and a cover (20). The cover (20) has engagement devices (13, 13′; 14, 14′; 23, 23′) when seen in a longitudinal direction of the drainage body (11), whereby the cover connects upper edges (12, 12′) of the drainage body (11) to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers (20) for different loads, for example while using the same drainage body (11), two types of engagement devices (13, 13′; 14, 14′) are provided on the drainage body.

Claims

1. A drainage channel having a drainage body (11) and a cover (20), wherein, when viewed in a longitudinal direction of the drainage body (11), the drainage body (11) and the cover (20) have continuous first engagement devices (12, 12′; 13, 13′) comprising a continuous row of upper teeth on the upper edge of the drainage body and a row of lower teeth (14, 14′) on the drainage body (11), the row of lower teeth disposed at a different height than the continuous row of upper teeth, and second engagement devices (23, 24) comprising longitudinal supports (22, 22′) on the cover (20), wherein the upper teeth engage with the second engagement devices such that the cover is secured to the drainage body and the cover connects upper edges (12, 12′) of the drainage body (11) to one another, transverse to the longitudinal direction, in a high tensile manner over the entire length of the drainage body, and wherein the row of lower teeth (14, 14′) engage a lower edge of the longitudinal supports (22, 22′) of the cover (20) to support the cover on the drainage body.

2. The drainage channel according to claim 1, characterized in that the second engagement devices comprise guide rails (23, 24) on the cover (20).

3. The drainage channel according to claim 1, characterized in that the upper teeth are disposed vertically above the lower teeth of the first engagement devices (12, 12′, 13, 13′, 14, 14′) of the drainage body (11).

4. The drainage channel according to claim 1, characterized in that the second engagement devices (24) are mounted on the cover (20) on a lower surface of peripheral groove supports (21).

5. The drainage channel according to claim 4, characterized in that the second engagement devices are formed as lower surfaces (23, 23′) of the peripheral longitudinal supports (22, 22′) of the cover (20).

6. The drainage channel according to claim 5, characterized in that stopper devices (15, 15′; 25, 25′) are provided, which limit a displacement range of the cover (20) relative to the drainage body (11) in the longitudinal direction thereof.

7. The drainage channel according to claim 1, characterized in that stopper devices (15, 15′; 25, 25′) are provided, which limit a displacement range of the cover (20) relative to the drainage body (11) in the longitudinal direction thereof.

8. The drainage channel according to claim 1, characterized in that the continuous row of upper teeth (13, 13′) are designed to interact with the second engagement devices (24) such that they limit a displacement range of the cover (20) relative to the drainage body (11) in the longitudinal direction thereof.

9. The drainage channel according to claim 1, characterized in that the drainage body (11) and/or the cover (20) are designed as plastic injection molded parts.

Description

(1) Preferred embodiments of the invention will be described in detail below on the basis of the Figures. Shown are:

(2) FIG. 1 a perspective partial view of a drainage body,

(3) FIG. 2 a perspective partial view (from below) of a cover,

(4) FIG. 3 a perspective partial view of the drainage body according to FIG. 1 having a cover that has been modified vis-a-vis the embodiment according to FIG. 2 and

(5) FIG. 4 a perspective partial view from another view angle of the object according to FIG. 3.

(6) In the following description, the same reference characters are used for identical or identically functioning parts.

(7) The drainage channel shown in FIGS. 1 and 2 comprises a drainage body 11 and a cover 20. Both parts are designed as plastic injection molded parts.

(8) Upper teeth 13, 13′ are provided on upper edges 12, 12′ of the drainage body 11, which upper teeth form a continuous row of teeth over the entire length of the drainage body. These teeth 13, 13′ engage with guide rails 24, which are provided on the lower surface of a groove support 21, 21′ of the cover 20 and which stabilize this groove support. The groove supports 21, 21′ project outwardly from longitudinal supports 22, 22′. When the cover 20, which is shown in FIG. 2, is fitted on the drainage body 11, the guide rails 24 engage with the upper teeth 13, 13′, so that a high tensile connection between the upper edges 12, 12′ of the drainage body (and at the same time, a shear-resistant connection) is formed. Then when in an assembled state, the drainage channel has a completely closed box profile, which has a high degree of stability.

(9) The engagement of the guide rails 24, which are shown in FIG. 2, with the upper teeth 13, 13′ of the drainage body 11 not only creates the above described high tensile connection, rather, the cover 20 is secured on the drainage body 11, likewise when viewed in the longitudinal direction of the drainage channel 10. This securing also occurs over the entire length of the drainage channel 10, so that a very high degree of stability is ensured.

(10) In addition, FIG. 1 also shows that a second row of teeth, namely the lower teeth 14, 14′, is provided on the drainage body 11. These lower teeth 14, 14′ come into contact with lower edges 23, 23′ of longitudinal supports 22, 22′ of a cover 20 having a different form, as is shown in FIGS. 3 and 4. The cover 20 shown thereon is formed out of sheet steel. Groove supports 21, 21′ of the cover 20 according to FIGS. 3 and 4 rest on the upper teeth 13, 13′, wherein here again, the continuous mounting of rows of teeth 13, 13′ ensures adequate stability in the case of vertical load. In addition, the cover 20 is resting such that it is supported twice; once with the groove supports 21, 21′ thereof on the upper teeth 13, 13′ and once with the longitudinal supports 22, 22′ thereof in the region of the lower teeth 14, 14′, so that increased stability with respect to vertical loads is ensured. In order to prevent a displacement of the cover according to FIGS. 3/4 in the longitudinal direction of the drainage channel 10, stopper projections 15 are provided at the ends of the drainage body 11, 15′, which projections engage with end edges 25, 25′ of the cover 20 (see in particular FIG. 4), when the cover 20 is displaced in the longitudinal direction of the drainage channel 10, for example by a braking or accelerating vehicle.

(11) From the above, it is clear that the above mentioned high tensile connection between the upper edges 12, 12′ is also ensured when a cover 20 having a different shape (as shown in FIGS. 3 and 4) is used together with the drainage body 11.
