Definitions

a safety device for a drainage channel is known for example from DE 42 41 707 A1.
a cover that can be fitted is attached to the upper edge of a channel body.
recesses are arranged essentially opposite one another.
a traverse engages in the recesses and is positioned transversely to the longitudinal axis of the gutter in the interior of the gutter.
the attachable cover is fastened without screws using a fastening device or by means of a screw connection on the crossmember against removal.
the crossbeam itself is provided with a clamping device at at least one end, so that the crossbeam is fixed in the recesses in the side inner walls.
a surface drainage device in particular a drainage channel, is known from DE 42 41 705 A1, which has a cover, which in turn can be attached to the channel body with attachment devices.
the fastening devices comprise a latch which is mounted on the cover and which can be moved into a locking position in the direction of a longitudinal edge of the cover. The bolt can still be moved from the locked position into an open position.
a screwless fastening of the cover can be carried out by means of the bolt described.
the fact that the bolt has latching devices which are in resilient engagement with the cover ensures that the bolt is fixed in the corresponding position at least in the locking position. This should make it impossible to open or remove the cover accidentally.
the rust protection systems described in the beginning in screwless or screwed form can only absorb low axial thrust forces.
a first basic idea of the invention is to propose a securing device for a drainage channel, which starts from a channel body which has a substantially U-shaped cross section and has opposite side walls.
An attachable cover grate lies on the side walls or the upper edge of the channel body. If necessary, the upper edge of the channel body is surrounded by a frame, the cover grille resting on the frame. The cover grille is guided or fixed laterally by the frame or the design of the upper edge of the channel body.
the cover grating is additionally fixed in the longitudinal direction by forces acting along the course of the drainage channel via a positive connection which is formed on at least one of the side walls.
This form-fitting connection can comprise a pin, which in at least one of the side walls of the channel body is hammered in, pressed in or inserted.
the pin itself protrudes upward and has a free section.
This free portion of the pin engages in an associated recess or hole in the grate, so that the aforementioned axial displacement, i.e. H. moving in the longitudinal direction of the channel is excluded.
the positive connection according to the first basic idea of the invention, i. H. the pin thus takes over the axial securing and the introduction of the thrust forces into the channel body when the cover grille is put on or put on.
a pin fixedly attached to the cover grille can engage in a cast-in hole or hole in the corresponding side wall of the channel or in a recess in a firmly cast-in sheet metal frame.
the shear forces are either indirectly or directly introduced into the channel body via the frame.
the positive connection comprises at least one cam formed on the frame or a protruding projection formed in the upper region of the side walls, which can also be an extension of the sheet metal frame itself, the cam or the Engage the extension in an associated recess in the cover grate, so that there is axial securing.
the pin and cam lock can be combined with one another.
the corresponding cover grille can be manufactured as a standard part, which has recesses corresponding to a pin and a sheet metal cam lock. This ensures that one and the same cover grating can be used with different drainage channels or different channel bodies, which either Pin lock, especially in the case of the frame-less embodiment, or a sheet metal cam lock, ie have a cam protruding upwards on the frame.
the cover grate used in this embodiment is further developed such that at least sections of existing support webs which run transversely to the channel have at least sections such a length that they positively surround the cross member on both sides after the cover grate has been put on.
This crossbeam also locking plate, is thus positively enclosed on both sides by the supporting webs, so that on the one hand by screwing or form-fitting connection using the crossbeam and on the other hand by the above-mentioned enclosing of the crossbeam, the system both without removing the cover grate and against axial displacement without additional measures are secured.
adequately dimensioned cover gratings, trusses and channel bodies are used.
the advantage according to the second basic idea of the invention consists in an axial self-locking by the support webs which are at least partially extended.
first and the second embodiment can be combined in accordance with the second basic concept of the invention in such a way that the edge profile of the cover grate is specially designed and at least two support rods are extended such that they can grip around the crossbar when the grate is in place.
At least one leg of the special edge profiling of the cover grate has a protruding pin-like extension which engages in an associated recess in the crossmember, as a result of which the amount of axial thrust forces that can be absorbed and dissipated increases.
the third basic idea of the invention is characterized by a combination of embodiments according to the second basic idea of the invention with a form-fitting pin or cam connection.
the cross member is largely freed of an axial force absorption by the additional pin or cam lock.
the trained overlapping side profiles of the grating or the special supporting webs explained above then take over the function of securing the crossbeam in position, so that the latter is prevented from sliding out of the cutouts in the side inner walls with repeated, changing loading of the channel body, in particular by driving over it.
a first embodiment of the safety device for a drainage channel is described with reference to FIGS. 1a and 1b.
a channel body 1, which forms a drainage channel, has opposite side walls 2. On the inside of the side walls 2 there are cutouts 3 for receiving a cross member 4.
the cross member 4 is introduced into the interior of the channel body 1 and fixed by twisting or pivoting in the recesses 3 such that it assumes a position transverse to the longitudinal axis of the channel body 1.
the cross member 4 is used to attach a cover grate 5.
the cover grate 5 is designed as a sheet metal grate.
the cover grating 5 is fastened to the cross member 4 by means of a screw connection 6 and rests on the upper edge 7 of a sheet metal frame 8.
the sheet metal part frame 8 accordingly forms a support for the cover grate 5 and at the same time serves to laterally fix the latter.
a bore 9 for receiving a pin 10 is made in at least one of the side walls 2.
the pin 10 can also be cast in during the casting of the channel body 1, so that the additional formation of a bore 9 can be omitted.
a second exemplary embodiment according to FIG. 1b shows a sheet metal cam lock.
the sheet metal part frame 8 is provided with an upwardly stamped and bent cam 20 which engages in an associated recess 21 on the cover grate 5.
the cam 20 of the sheet metal frame 8 is already formed during the manufacture of the sheet metal frame itself by a stamping and bending step, so that an axial locking can be formed in a simple manner without an additional locking pin.
1c shows an embodiment with a combined pin and sheet metal cam lock.
the cover grate 5 can be manufactured as a standardized component, which has the recesses 21 and 13 in the lower region 22 of its sheet metal profile, which have such a shape in diameter or in size that either the cam 20 or the free section 11 of the pin 10 can be included.
the cover grating can have a cam or extension directed towards the bearing surface of the frame or the side walls in its lower region of the profile, which cam in a corresponding hole or recess in the frame and / or in an upper section of the side walls of the channel body engages.
the vertical side locking surface 23 and in particular the horizontal contact surface 24 of the cover grate 5 in Connection with the pin 10 and / or the cam 20 assigned an additional function with regard to the absorption and the deflection of axially acting thrust forces.
a channel body 1 with side walls 2 and a crossbar 4 arranged in recesses 3 are again assumed.
the securing device according to FIGS. 1a-1d can be used advantageously in particular if sheet metal webs, meshes or cast gratings are to be fastened axially without a locking plate or crossbar.
a cast web grate 30 is present as a cover grate.
the cast web grate 30 has a multiplicity of support webs 31 which run essentially transversely to the channel body 1 and which, according to FIGS. 2a, 2b and 2d, are downward, ie. H. are tapered towards the bottom of the gutter.
Inlet openings 32 are present between the supporting webs 31.
at least two adjacent supporting webs 31, in accordance with FIGS. 2a and 2b, the supporting webs 310 and 320 are facing downwards, ie. H. extended towards the channel bottom that the opposite inner sides of the supporting webs 310 and 320 encompass at least a portion of the cross member 4 in a form-fitting manner.
FIG. 2c shows a variant of a cast web grate 30 which has shortened or shorter support webs 330.
the edge profile 34 of the cast web grate 30 is designed in such a way that the crossbar 4 is positively gripped in a section directed towards the side inner wall 2.
the special edge profile comprises two opposite legs 35, at least one of which has a U-shaped section for gripping the cross member 4.
the inner sides of the U-shaped cutout namely the sides which are in operative connection with the cross member 4, can have a wedge surface shape, so that there is a play-free locking of the cast web grating 30.
edge profile 34 can have a pin-like extension, not shown, which engages in an associated recess of the crossbar 4, not shown.
FIG. 2c is particularly advantageous when a grate is used, the supporting webs of which are short or with a grate, e.g. B. mesh, the supporting webs can not absorb axial forces.
the cast iron locking device on the basis of extended supporting webs can be combined with the edge profile locking device in a lateral section of the cross member.
the third exemplary embodiment there is a channel body 1 with side walls 2, a cross member 4 being arranged essentially transversely to the longitudinal direction of the channel body in a recess 3 in the side inner walls.
the cast web grate 30 of the third exemplary embodiment has a bore or recess 41 in an edge section 40 of the edge profile for receiving a free section 11 of a pin 10, which is fixed in the side wall 2 of the channel body 1.
the gripping of the crossbeam 4 with the supporting webs 310 and 320 then preferably serves to secure the position of the crossbeam itself, so that it does not turn out or pivot out of the recesses 3 in the event of dynamic and alternating loads and there is therefore a risk that the covering grate in question will be flung upwards .
