Definitions
- the invention relates to a cover for a drainage device, in particular a drainage channel, with a channel body, the cover which can be placed on an upper edge of the channel body and which has locking webs projecting into the channel body and with at least one fastening element for securing the cover on the channel body, or on a frame lying on the channel body to reinforce the upper edge, according to the preamble of claim 1.
- Drainage arrangements in particular drainage channels or the like, in which the cover can be fastened on the channel body with the aid of fastening elements, are known.
- a drainage channel with cover grate that can be attached to a channel body is known.
- the locking of the cover grate is achieved by means of a leaf-shaped cover grate locking spring which has oppositely formed projections which engage in recesses in the side walls of the channel body. After engagement or engagement of the projections, the grating locking spring assumes an essentially tension-free position in the interior of the channel body.
- Through locking brackets with angled legs attached to the cover grille When the cover grille is inserted into the channel body, the cover grate is locked while overcoming the spring force.
- This known drainage device with a grating locking spring has the disadvantage that the locking spring is arranged inside the channel body, namely transversely to the longitudinal axis. This means that the channel cross-section is not clear, which can lead to blockages or make cleaning work much more difficult.
- Another disadvantage is that the walls of the channel body have recesses - which serve to engage the locking spring. The recesses are arranged essentially halfway up the channel body. The stability and the service life of the channel body are impaired in view of the high surface loads.
- the invention is therefore based on the object of developing a cover for a drainage device with a fastening arrangement of the type mentioned in such a way that on the one hand a durable fastening of the cover on the gutter body is ensured with simple manufacture and assembly of the fastening arrangement and on the other hand enables a free gutter cross section becomes.
- a basic idea of the invention is that the fastening element is guided through the recess.
- the stability of the fastening does not depend solely on the fastening element and its stability.
- the connection is a snap-in connection. Since the locking takes place in the upper area of the channel body, a free channel cross-section is available after the cover has been placed on the channel body. This ensures optimized hydraulic performance.
- the recess preferably has a lower edge, so that the fastening element is inserted between this lower edge and a locking surface of the recess in the locked state.
- the fastening element can then be made very simple and light, since it acts like a door latch snapped into a lock latch.
- the fastening element which protrudes from the recesses, engages below the frame in the recesses in the body walls, the frame serving as a holding element for the locking.
- the locking takes place in the upper area of the channel body immediately below the cover.
- the fastening element is preferably designed as a locking spring.
- the fastening element preferably has a central section, at the ends of which projections are provided, through which the cover is locked with the channel body.
- the projections protrude from the recesses in the locking bars.
- the middle section extends immediately below the cover and is preferably attachable to a lower surface of the cover. This ensures a better hold of the fastener and increases the security of the lock.
- the projections have a first and a second angled sections.
- the second angled section is nose-shaped and engages in the recess of the locking web in order to connect the fastening element to the cover.
- the free ends of the fastening element extend in the direction of the interior of the channel.
- the frame is preferably angled in the direction of the channel bottom and forms a locking surface for engagement with the fastening element.
- the angled frame section and the locking webs also projecting downward in the direction of the channel bottom run next to one another when the cover is in place on the channel body.
- the fixing core elements are preferably formed such that while placing the cover on the channel body which projects out of the recesses of the cover retaining lugs of the fixing elements of the channel body or the frame ent slide ⁇ long.
- the fastening elements can be elastically deformed in the direction of the interior of the channel by exerting a compressive force. In a final resting position of the cover on the channel body, the retaining lugs snap into the cutouts. This latching connection on the one hand achieves a permanent locking of the cover and on the other hand ensures adequate security against undesired lifting of the cover.
- the cover is preferably stretched on the body or on the frame by the fastening element in the locked state of the cover. The cover is thus fixed in the channel body without play.
- the fastening element is preferably designed in such a way that the force required to deform the fastening element is lower than the force required to release the locking device and to lift off the cover.
- the cover is rather attached to the channel body and only removed when necessary repair or cleaning work is required.
- the recesses in the channel walls, in which the retaining lugs of the fastening element are attached in the locking position, are preferably designed to be closed in the outer surface area. Soiling is avoided on the one hand and on the other hand the mechanical stability of the channel body, which is stressed with high loads, is increased.
- the width of the fastening element preferably corresponds essentially to the width of the cutouts in the channel walls. In addition to locking, an additional horizontal securing of the cover against the channel body can thus be achieved. Therefore, additional anti-displacement devices are unnecessary.
- the fastening element can preferably be formed in one piece, a partially one-piece design also being possible.
- the fastening element can be formed both from metal and as a plastic part, in particular as an injection molded part.
- the cover can be formed from sheet steel, stainless steel sheet or cast iron as well as from plastic.
- the cover is preferably designed as a web grate.
- the fastening element can be dimensioned such that the central section of the fastening element can be arranged under a web of the web grate. The fastening element is thus inaccessible from the surface and vandalism protection is ensured.
- Figure 1 shows a cross section through a drainage channel with a locking spring
- Figure 2 is a perspective view of the locking spring
- Figure 3 is a perspective view of a cover with an inserted locking spring.
- FIG. 1 shows a cross section through a drainage channel with a locking spring 30.
- the drainage channel has a channel body 10 that can be installed in the floor and a cover 20 that can be placed on the channel body 10.
- the locking spring 30 is used to attach the cover 20 to the channel body 10.
- the channel body 10 is essentially V-shaped, but another configuration, for example a U-shaped one, is also possible.
- the channel body 10 is made of polymer concrete and consists of a lower body with side walls 11 and a frame 14.
- the frame 14 serves on the one hand to reinforce the upper edge 12 of the channel walls 11 and to support the cover 20 and on the other hand as a holding element for locking the Cover 20.
- the frame 14 is made of metal.
- the cover 20 is bent as a web grating made of sheet metal, a different design, for example as a mesh grating, is also possible.
- the cover 20 has a curved double surface 24 for the respective longitudinal edges.
- the double surface 24 integrally merges into locking webs 21, which are bent downward in the direction of the channel bottom.
- the locking webs 21 which are bent downward have ends 26 which tilt upwards in the surface direction by punching out.
- the ends 26 of the locking webs 21 serve as a support for the cover 20, in the area which is farthest from them. This increases the bending strength of the cover 20 considerably.
- the double surface 24 lies on the frame 14.
- the frame 14 is angled in the direction of the channel interior.
- the frame 14 also has a projection 16 which is dimensioned such that its height corresponds to the height of the double surface 24 and thus the edges of the cover 20 are encompassed by the frame 14 in the longitudinal direction of the channel.
- the locking webs 21 cover the cutouts 13, which are provided in the channel walls 11 for locking.
- the locking webs 21 are provided with recesses 22 see.
- the recesses 22 correspond to the recesses 13 and 17 in the channel walls 11 and frames 14.
- the recesses 22 are dimensioned such that the locking spring 30 is guided into the recesses 22.
- the recesses 13 in the channel walls 11 are designed such that they are partially covered by an angled frame section 15.
- the frame section 15 has a locking surface 17.
- the frame 14 thus serves not only to protect the upper edges 12 of the channel walls 11, but also as a locking means.
- the recesses 22 have a lower edge 36.
- the lower edge 36 is designed such that in the locked state, the fastening element 30 is inserted between the lower edge 36 and the locking surface 17 of the recess and a shear force is applied when the cover 20 is lifted off.
- the locking spring 30 is of sheet-like design and, as can also be seen from FIG. 2, has a central section 31 and two projections 32 designed in mirror symmetry.
- the projections 32 are designed to taper conically and have a first curved section 33 and a second curved section 34.
- the second section 34 is nose-shaped and serves to fasten the locking spring 30 on the one hand with the cover 20 and on the other hand to fasten the cover 20 with the inserted locking spring 30 on the channel body 10.
- the free ends 35 of the locking spring 30 project in the direction of the channel interior.
- Figure 3 shows a perspective view of the cover 20 with inserted locking spring 30.
- the recesses 22 in the locking webs 21 are arranged such that the inserted locking spring 30 is attached with its central portion 31 on the underside of a web 25.
- the central section 31, which is substantially longer than the projections 32 is dimensioned such that its length corresponds essentially to the width of the cover.
- the width of the middle section 31 corresponds essentially to the web width.
- the retaining lugs 34 engage in the recesses 22 of the cover 20 and protrude from them.
- the retaining lugs 34 slide along the angled frame section 15 while exerting a compressive force.
- the first angled sections 33 of the projections 32 are moved in the direction of the interior of the channel until the area of the recesses 13 of the channel walls 11 is reached and the retaining lugs 34 snap under the frame section 15. As a result, the cover 20 is locked on the channel body 10.
