Benefits of technology

[0009] It is an object of the invention to provide a fixing device for a cover placed on an upper rim of a channel body, runoff box or similar structure that can be embedded in the ground, as part of a drainage channel, road or yard gully or similar surface drainage devices, that is developed further than the prior art in such a way that a secure locking of the cover is obtained by simple manipulation, while at the same time the cover is optimally seated.

Embodiment Construction

[0042] In the following description, the same reference numerals are used for identical parts or parts with identical actions.

[0043] The perspective drawings in FIG. 1 show a second fixing element 20a and a first fixing element 10a, which corresponds to the second element 20a and can be received therein; said first fixing element is disposed on a cover 7 that can be set onto an upper rim 6 of a body 2 embeddable in the ground. The fixing element 20a is fastened within a wall 3 of a channel body 2. It is advantageous that the element 20a is thereby protected and disposed in a space-saving manner, so that a free channel cross section is available for the materials that are to be guided away in the surface drainage device.

[0044] The second fixing element 20a has the overall shape of a parallelepiped and accordingly comprises two side walls 30, 30′ disposed opposite one another, a front wall 28, a back wall 29 opposite the front wall 28, an upper wall 31 and a lower wall opposite the ...

Abstract

The invention relates to a fixing device for a cover of a drainage channel, road or yard gully or similar surface drainage devices, said cover being placed on an upper rim of a channel body, runoff box or similar body that can be embedded in the ground, with first fixing elements on the cover and second fixing elements on the body embeddable in the ground, such that the first fixing elements and the second fixing elements in each case can be brought into snapping engagement with one another to retain the cover on the body. The fixing device achieves a secure locking of the cover by simple manipulation, while simultaneously optimizing the cover's seating. To accomplish this the first fixing elements and / or the second fixing elements each comprise at least one damping section with a contact surface between the cover and the body embeddable in the ground, so that when locked in position the cover is spaced apart from the upper rim of the body.

Description

RELATED U.S. APPLICATIONS [0001] Not applicable. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable. REFERENCE TO MICROFICHE APPENDIX [0003] Not applicable. FIELD OF THE INVENTION [0004] The present invention relates to a fixing device for a cover of a drainage channel, road or yard gully or similar surface drainage devices, said cover being placed on an upper rim of a channel body, runoff box or similar structure that can be embedded in the ground. BACKGROUND OF THE INVENTION [0005] For industrial purposes as well as in the public or private sectors surface drainage devices are employed to carry away rain or muddy water, water that has been used for cleaning, or environmentally hazardous liquids. When used to drain roadways, parking lots or pedestrian zones, for example, such devices must be able to withstand high static and dynamic loads. A crucial factor here is that the cover be seated and fixed on the body that can be embedded in the ground, s...
