Definitions
- the invention relates to a drainage device for surface drainage, in particular drainage channel, with a, preferably elongated, base body, a cover covering an opening of the base body, preferably a cover grate, and with at least one latching locking device for latching locking of the lid on the base body, the locking device being at least one has a first latching element on the base body and at least one second latching element which can be brought into direct engagement with the first latching element and is formed in one piece with the cover.
- Drainage devices of the generic type are used in particular in traffic areas for vehicles, cyclists or pedestrians and are designed, for example, as drainage channels.
- cover grids For the purpose of simple assembly, maintenance and cleaning, it is necessary that the cover grids can be easily removed from the drainage device and put back on again.
- the demand for the easiest possible usability of the cover grids on the other hand, there is the need to secure the anchoring of the cover grids to ban the risk of accidents from unintentional loosening. Frequent actuation or permanent mechanical stress, for example due to vehicle traffic, should not loosen the anchoring of the cover grate if possible.
- Elastic in one direction at an angle to the plane of the cover means that when force is exerted, the section carrying the second latching element and / or the section carrying the first latching element is subjected to a pivoting movement in a direction angular to the plane of the lid due to the elasticity caused by the elasticity, whereby a resetting moment arises in exactly the opposite direction due to the elasticity.
- a large number of fastening devices are known from the prior art which are intended to effect such anchoring of the cover grate on the drainage device.
- a cover grate is known, for example, from EP 0 811 732, in which the cover grate is to be fixed laterally by clamping by means of specially designed, longitudinally elastic webs. In the locked state, cams arranged on movable ends of the longitudinal webs engage in corresponding laterally arranged cutouts on the base body.
- a disadvantage of the known drainage devices is that they often require special tools for locking the grating on the base body. Furthermore, the sometimes very complex locking devices allow the grating to rest securely on the channel body, but they can only be solved with considerable effort during maintenance. Due to the intended purpose alone, sediments from earth, sand and organic material are deposited in every recess of the drainage device accessible from the surface. It is precisely in these areas that, in the case of conventional drainage devices, the actuating and latching elements for locking the cover grids are mostly on the base body of the drainage device.
- the object of the present invention is therefore to provide a drainage device for surface drainage of the generic type, in which the cover grate can be locked to the base body in a particularly simple but also secure manner. In particular, the use of special tools for the assembly or subsequent maintenance of the drainage device should be avoided. Furthermore, the locking device should be designed in such a way that it is still easily detachable and easy to clean, even if sediments are introduced considerably.
- the drainage device for surface drainage in particular drainage channel, comprises a base body, a cover covering an opening of the base body and at least one latching locking device for latching locking of the cover on the base body.
- the locking device has at least one first latching element on the base body and at least one second latching element which can be brought into direct engagement with the first latching element and is formed integrally with the cover.
- the generic dewatering device is developed in such a way that at least one projection, which projects in the direction of the base of the base body, is essentially rigidly anchored, preferably integrally formed, which carries the second latching element. Due to the special location and design of the locking device, the cover grate can also be actuated when there is considerable entry of soil, sand or organic material.
- the locking elements of the locking device are integral components of the cover or the base body; Accordingly, no further locking elements, such as screws, clamps and the like, are necessary for the locking.
- At least one section of the projection that carries the second latching element and / or at least one section of the base body that supports the first latching element is designed to be elastic, preferably in one direction at an angle to the plane of the cover. hereby can be easily supported a snap-in of the two locking elements and the placement of the lid on the base body can be facilitated.
- the sections carrying the first latching element and / or the second latching element are designed to be elastically pivotable about an imaginary pivot axis, which preferably runs parallel to or lies in the plane of the cover.
- the sections carrying the first and / or second latching element each span a plane that runs at an angle, preferably transversely, to the longitudinal extent of the base body. It is thereby achieved that unlocking of the locking device in the case of forces acting in the longitudinal direction on the cover of the drainage device is made more difficult or is completely prevented.
- the cover preferably has ribs, in particular for stiffening, the projection being formed by a rib or arranged on a rib, preferably molded on.
- the ribs are at least partially designed as transverse ribs extending between the longitudinal sides of the cover and the projection is located on these transverse ribs.
- the first and second locking elements comprise complementary cutouts and thickenings. These can preferably be configured such that the first locking element on the base body has a comb and the second locking element has a complementary groove.
- the designs of the latching elements which are in principle very easy to manufacture and are therefore associated with low manufacturing costs, have proven to be very robust against environmental influences and mechanical stress. If soiling or sediment is introduced in the area of the locking elements, cleaning of the locking elements, for example by means of high-pressure water cleaning, is special easily possible because all components of the locking device are easily accessible.
- first and second locking elements can alternatively have locking lugs that can be brought into engagement with one another.
- the locking lugs of the first and second locking elements are usually directed towards one another and engage behind one another in the locking position and thus in the closed state of the locking device.
- the base body has at least one support surface for the cover, a recess is formed in the region of the support surface and the first latching element is arranged within the recess. If the base body has a frame that serves to receive the cover, then the first latching element is preferably integrated in the frame. With the measures mentioned it can be achieved that the cover grate is prevented from moving in the longitudinal direction due to mechanical stress. Furthermore, the assembly and repositioning of the cover grille after maintenance on the base body is facilitated, because the design of the locking elements supports the pre-positioning of the cover grate on the base body. In the assembled state of the drainage device, the second latching element protrudes into the recess of the base body and engages with the first latching element.
- the second latching element is arranged on the portion of the projection which is removed from the cover.
- the section of the projection which is removed from the cover can expediently be wider than the remaining section of the projection and preferably have the shape of a rod lying approximately parallel to the plane of the cover.
- a device for displaceably arranging the cover on the base body is provided.
- the lid is fixed to the base body so that it cannot be moved relative to the base body if forces are introduced into the cover in the direction of its extension due to external influences.
- forces acting in the longitudinal and / or transverse direction mainly occur when the cover is run over by vehicles.
- Particularly high forces of this type are generated in particular when braking or accelerating. Because of such forces, the cover tends to shift relative to the base body.
- the locking device is subjected to an increased load and there is a risk of faster wear or even damage.
- a movement lock is created which prevents unintentional movement by absorbing the forces introduced into the plane of the cover and thereby relieving the locking device.
- the device for displaceably arranging the cover has at least one pair of engagement means which can be brought into engagement with one another, of which the first engagement means is arranged on the cover and the second engagement means is arranged on the base body.
- the first engagement means can have at least one nose and the second engagement means can have at least one recess for receiving at least one nose; a reverse training is also conceivable.
- the base body is provided with at least one support surface for the cover, the first engagement means can expediently be formed on the underside of the cover and the second engagement means on the support surface of the base body.
- the nose rises from the support surface and the recess on the underside of the cover forms a corresponding recess, into which the nose engages in order to fix the cover against the support surface on the base body so as to be displaceable.
- the cover has ribs, with the edge sections of which the cover rests on the support surface on the base body, at least one recess can preferably be formed by the gap between two adjacent edge sections of the ribs.
- the base body usually has at least one side wall section; in this case, the device for the displaceable arrangement of the cover can alternatively or in addition to the previously described embodiment have at least one stop for abutment against the side wall section in order to form a further displaceable locking device. If the base body has at least one support surface for the cover, below which the side wall section is located, the stop can form an extension arranged on the underside of the cover.
- the base body has a frame which serves to receive the cover, it is finally expedient to design the second engagement means on the frame.
- Figure 1 is a plan view of a drainage channel for surface drainage according to a first embodiment.
- FIG. 2 shows a sectional view along the line II-II through the drainage channel according to FIG. 1;
- FIG. 3 shows a sectional view along the line III-III through the drainage channel according to FIG. 1;
- FIG. 4 shows an enlarged detail from the drainage channel according to FIG. 1 in the area of the locking elements of a locking device along the line IV-IV;
- FIG. 5 shows a cover grating for a drainage channel according to a second exemplary embodiment in a side view cut in half on one side;
- FIG. 6 shows a cross section through the cover grate according to FIG. 5; 7 shows a perspective bottom view of the cover grate according to FIG. 5; and
- FIG. 8 shows a section of a frame of a base body of the drainage channel according to FIG. 1 in a fragmentary perspective view.
- FIG. 1 schematically shows a top view of a drainage channel 10 for surface drainage according to a first exemplary embodiment, as is typically used in traffic areas.
- the drainage device 10 is composed of a cover grate 22 and a base body 12. From the base body 12, only a frame 14 running in the longitudinal direction of the drainage device 10 can be seen from the perspective of FIG.
- the tops of the grating 22 and the frame 14 form a plane which serves as a traffic area.
- FIGS. 2 and 3 show sectional views along the lines II-II and III-III of FIG. 1.
- the base body 12 has an elongated opening 16 lying in the plane of the traffic area, which opens into a channel body 17 and is covered by the cover grate 22 in the assembled state of the drainage channel 10. Water penetrating through the opening 16 is collected at the bottom 18 of the channel body 17 and discharged.
- the base body 12 has a frame 19 placed on the channel body 17.
- An enlarged section of the frame 19 is also shown in FIG. 8.
- the frame 19 forms, as can be seen in FIGS. 3 and 8, on its sides directed towards the inside of the base body 12 in each case a shoulder 20 spaced downwards from the plane of the traffic area.
- This paragraph 20 has a flat, horizontally oriented top, which serves as a support surface 21 for the cover grate 22.
- An elastic plastic insert 24 protruding from the top of the shoulder is usually provided for sound absorption.
- the base body 12 can for example consist of concrete and the frame 19 made of a corrosion-resistant metal or plastic.
- the plane 15 of the traffic surface of the cover grating 22 is formed in the exemplary embodiment shown by an outer circumferential web 26, five longitudinal openings 27 and four parallel longitudinal webs 28 spaced apart from one another.
- the circulation web 26 is somewhat widened on its two longitudinal sides and, when the drainage device 10 is assembled, lies, as can be seen in the cross section of FIG. 3, with its underside on the contact surface 21 of the elongated projections 20 or on their elastic plastic inserts 24.
- transverse ribs 32 extend between the longitudinal sides of the cover grate 22 (only partially visible in FIG. 1).
- the transverse ribs 32 are connected in one piece to the other elements of the cover grate 22, in particular the circumferential and longitudinal webs 26, 28, and essentially serve to stiffen the cover grate 22.
- a relative position of the individual transverse ribs 32 in the cover grate 22 can be seen from the section shown in FIG. 2 along the line II-II in FIG.
- Two of the transverse ribs 32 shown in cross section in FIG. 2 are provided with tabs or projections 34, 36 pointing in the direction of the bottom 18 of the base body 12, on which locking devices 38, 40 are arranged.
- 32 locking devices can also be provided on further transverse ribs.
- FIG. 4 shows, by way of example, an enlarged partial section of the drainage device 10 in the area of the locking device 40, specifically along the line IV-IV of FIG. 1.
- the locking device 40 comprises a first locking element 42 on the base body 12 and a second locking element 44 on the grating 22 that can be brought into direct engagement with the first locking element 42.
- the first latching element 42 is designed as a comb extending transversely to the longitudinal extent of the base body 12 and is seated approximately in the middle on a side wall 50 of a downward-facing U-shaped section 50 provided on the inside of the frame 19, which is shown in paragraph 20 forms a depression or a type of bead.
- the side wall 50 carrying the first latching element 42 spans a plane that extends transversely to the longitudinal extent of the base body 12.
- the second latching element 44 is designed as a groove which runs transversely to the longitudinal extent of the base body 12 and is complementary to the ridge of the first latching element 42 and is arranged on a side wall 56 of the projection 36 of the transverse rib 32.
- the projection 36 carrying the second latching element 44 spans a plane that extends transversely to the longitudinal extent of the base body 12.
- the second latching element 44 is connected in one piece to the cover grate 22.
- the second locking element 44 provided as a groove is formed on both side ends 54a of a lower end portion 54 of the projection 36. As can be seen in FIG. 3, the lower end section 54 extends with its two side ends 54a approximately over the entire width of the cover 22, while the remaining projection 36 has a smaller width.
- the individual latching elements 42, 44 are each arranged on side walls of the projections 34, 36 that bear them and are formed on a transverse rib 32.
- the projections 34, 36 are essentially rigidly formed on the cover grille 22 via the respective transverse rib 32, they nevertheless have a certain elasticity, so that after the cover grate 22 has snapped in, they are under slight tension and thus the necessary holding force of the locking devices 38, 40 and thus the locking is realized.
- the cover grate 22 is placed on the base body 12, the locking devices 38, 40 facilitating exact positioning. After the covering grille 22 has been placed on it, it is pressed vertically downward, the first locking elements 42 designed as combs slide over the side walls 56 of the transverse ribs 32 until they engage in the groove-shaped second locking elements 44.
- the projection 36 of the associated transverse rib 32 carrying the second locking element 44 and / or the side wall 50 of the U-shaped section 52 on the frame 19 which supports the first locking element 42 are in this case to facilitate assembly and to achieve the locking effect in one direction formed at an angle to level 15 of the cover grate 22 elastically yielding.
- the two locking devices 38, 40 in the exemplary embodiment shown are mirror-symmetrical to one another, in that the first locking elements 42 designed as a comb are directed towards one another and the second locking elements 44 designed as a groove are directed away from one another.
- the transverse ribs 32 provided with the second latching element 44 are subjected to a tilting movement directed towards one another, which in turn causes a torque acting in the opposite direction to achieve an engagement of the second latching element 44 arises with the first locking element 42.
- one of the locking devices 38, 40 forms an abutment with respect to the other locking device.
- the locking devices 38, 40 can also be mirror-symmetrical to each other in the opposite direction.
- means for latching the cover grille 22 onto the base body 12 can also be provided, for example, which include complementary recesses and thickened areas on the transverse ribs 32 or on the base body 12.
- Several locking elements of this type can also be arranged on a transverse rib 32 and accordingly in the region of the base body 12. So at the arrangement shown in Figure 4, for example, the left side wall of the transverse rib 32 and the recess 52 seen from the viewer each carry a locking element.
- the arrangement of the latching elements in the area of the walls perpendicular to the traffic area has proven to be particularly useful, since this can greatly reduce the deposit of sediments in the area of the locking devices 38, 40.
- FIGS. 5 to 7 show a cover grating 122 of a second exemplary embodiment of a drainage channel.
- This grating 122 is suitable for resting on a base body, as has already been described with reference to FIGS. 1 to 4.
- the base body 12 according to the first embodiment can also be used for the second embodiment described below without significant changes.
- the top of the cover grate 122 is configured in the same or similar manner as shown in FIG. 1 using the cover grate 22 of the first exemplary embodiment.
- FIG. 5 shows the cover grate 122 with a left half-sided longitudinal section along a line corresponding to the line II-II of FIG. 1
- FIG. 6 shows a cross section through the cover grate 122 along a line corresponding to the line III-III of FIG. 1.
- This cover grate 122 differs from the cover grate 22 according to the first exemplary embodiment in that the transverse ribs 132 extend over the entire width of the cover grate 122 and the cover grate 122 rests only with the lateral end sections 132a of the transverse ribs 132 on the contact surface 21 of the base body 12.
- the cover grate 122 when the cover grate 122 is supported on the support surface 21 of the base body 12, there are gaps between two adjacent transverse ribs 132 between the end sections 132a, where the cover grate 122 does not rest on the support surface 21 of the base body 12.
- the cover 122 differs from the first embodiment in that locking devices 138, 140 are designed differently.
- the locking devices 138, 140 also have a locking function; however, in the second embodiment, the second locking elements 144 are wedge-shaped Locking projections formed.
- the second locking elements 144 designed as wedge-shaped projections engage under the first locking elements formed on the base body 12, which are arranged in the same or similar manner as the first locking elements 42 in the first embodiment and are also designed in a similar manner as combs or projections.
- the second latching element 144 is also seated on a lower end section 154 of the projection 134 or 136 in the second embodiment.
- the second latching element 144 is designed as a rod in the second embodiment which is self-supporting extends parallel to the level of the grating 122 over the entire width of the grating 122, while the projection 134 and 136 carrying the second latching element 144 has a significantly smaller width, as can be seen in particular from FIGS. 6 and 7.
- the construction of the second exemplary embodiment essentially corresponds to that of the first exemplary embodiment, so that no further description is necessary here.
- a stainless steel spring for. B. by pouring to arrange, which is biased towards the first locking element on the base body and can be brought into engagement therewith.
- cutouts 60 and 160 are formed on the underside of the cover 22 and 122, respectively, into which lugs 62 arranged on the base body 12 engage.
- the cutouts 60 and the associated lugs 62 are shown in dashed lines in FIG. 2, while only the lugs 62 can be seen in a perspective view in FIG.
- two spaced-apart lugs 62 are arranged on the bearing surface 21 of the shoulder 20 formed on the frame 19, so that the lug 62 rises from the bearing surface 21 (cf. in particular Figure 5).
- the associated cutouts 60 are formed on the underside of the circumferential web 26 of the cover 22.
- At least one nose 62 is arranged on each long side of the base body 12 and engages in an associated recess 60 formed on the corresponding long side of the cover 22.
- the two recesses 160 are each formed by a gap on both longitudinal sides of the cover grate 122, which, when the cover 122 rests on the base body 12, between a lateral end section 133 of a central transverse rib 132 widened in the longitudinal direction of the cover grate 122 and the lateral end section 132a of the adjacent transverse ribs 132 arises.
- the noses 62 which project from the support surface 21 of the base body 12 (see FIG. 5) engage in these gaps which serve as the cutout 160.
- the width of the widened lateral end section 133 in the longitudinal direction of the cover grate 122 is dimensioned such that it essentially fits into the gap formed between the two noses 62 arranged in pairs, and thus both lugs 62 essentially abut this widened lateral end section 133 in order to achieve a locking with the smallest possible tolerance to achieve the desired securing against displacement.
- cutouts 60 or 160 and lugs 62 described above essentially serves for locking against displacement in the longitudinal direction of the cover grate 22 or 122.
- extensions 164 in the cover grate 122 are provided in the form of extensions 164 in the cover grate 122 according to the second exemplary embodiment. As can be seen in FIG. 7, these extensions 164 are formed on transverse ribs 132 and extend downward. Alternatively, however, it is also conceivable to arrange the extensions, for example, at a different location on the underside of the grating. The extensions 164 are positioned such that they form a stop for abutment against the respectively adjacent inner side wall section 19a of the frame 19 of the base body 12, which adjoins the support surface 21 below this (see FIGS. 3 and 8). However, it is also conceivable that the extensions serving as a stop are dimensioned in their length such that they can be brought into contact not only with the inside wall section 19a of the frame 19, but also with the inside wall section 17a of the channel body 17 adjoining it.
