Ways to carry out the invention

In Figures 1 and 2a, an inventive drainage channel from above or a part of it from the side shown. The drainage channel has a gutter body 1 of a casting material, in particular of polyester concrete, on. The gutter body 1 is open at the top. Its cross section is usually u- or v-shaped. At the upper longitudinal edges of the channel body 1 is a top frame or as shown here, a gutter frame 2 attached. This gutter frame 2 is preferably made of metal and is used in the manufacture of the gutter with the gutter body 1 shed.

FIG. 2b shows a cross section through such a gutter frame 2. she consists in this example from a main carrier 20, to which one to the gutter inside directed towards spring lug 21 is formed. At appropriate places are recesses 22 in the spring lugs 21 available.

In these recesses 22 can each be a latching element 3 latch and resilient hold. This latching element 3 has the shape of pockets, whose opening for Gutter inside is directed. Preferably, the latch member 3 is additional shed with the frame 2. A cross bar 4, also called Traverse, can be fixed in hold two opposing latching elements 3. For this he will be one vertical pivot axis A is rotated until it locks in its final position. In Figure 1 is the crosspiece 4 shown during insertion into the latching elements 3, before reaching its end position has reached. In its final position, it runs approximately perpendicular to the longitudinal axis L the gutter.

For easier insertion of the cross bar 4, the latching elements 3 corresponding Guides on which only one screwing in a particular direction of rotation enable. This direction of rotation is shown in Figure 1 with an arrow D. The crossbar 4 is, when it is locked in its final position, in the reverse direction fixed and can not be destroyed or without suitable tool from its anchorage be solved.

In FIGS. 3a to 3d, the transverse web 4 according to the invention is shown in detail. He has a first and a second head part 40, 41 which, via a bridge 42 connected to each other. At the outer end-side end faces 40 ', 41' of the Headboards 40, 41 each have a tongue 43, 44 arranged. Preferably, the transverse web 4 formed in one piece and consists as well as the latching elements 3 made of a plastic. In this case, the tongues 43, 44 are integrally formed on the head parts 40, 41. in the Example shown here is only one tongue 43, 44 arranged on each side. It however, they can be several. The tongues 43, 44 extend approximately half the height of the head portion 40, 41, preferably with the lower edge the head parts 40, 41 are aligned.

The tongues 43, 44 are arranged at an angle α to the respective end face 40, 41 ', this angle α lies in a horizontal plane. The tongues are 43, 44 viewed in the longitudinal direction of the channel on diagonally opposite ends of the head parts 40, 41 arranged. As a result, when turning the crosspiece in the direction of rotation D the closed part of the tongue 43, 44, i. its junction with the headboard 40, 41, in advance, as shown in Figure 1. Otherwise, the cross bar 4 is symmetrical educated. He thus has a 180 ° rotational symmetry.

In the head parts 40, 41 each have a slot 45, 46 is present, which in horizontal Direction extends from the end-side end faces 40 ', 41' approximately in the Center of the head portion 40, 41 extends and adjacent to the tongues 43, 44 and above this is arranged. The slots 45, 46 extend approximately to the middle of the head part 40, 41. These slots 45, 46 thus divide the head parts 40, 41 into one each upper and lower part, which are formed slightly resilient thanks to the subdivision.

The bridge 42 is, as seen in Figure 3c, formed bent, the upper Edge straight and the lower edge forms the bow. From Figure 3b is based on the dashed Lines can be seen that the bridge 42 is triangular from top to bottom extended.

The head parts 40, 41 are formed substantially cuboid, wherein they each have a through opening 47 extending from top to bottom. These Through opening 47 is in the direction parallel to the longitudinal axis L of the channel with vertical Walls 48 and in the direction transverse to the longitudinal axis L with them from top to bottom first tapered and then widening walls 49 limited. This opening forms a receptacle for splayed legs 71 of a spreader clip shown in FIG. 8e, by means of which a cover, not shown screwless on the gutter body 1 attached and can be fixed in this position passable and accessible. Such Spreizklammern 7 and the associated receiving opening 47 with the oblique Walls 49 are described in detail in EP-A-0'931'885. In contrast to EP'885, however, the receiving opening 47 is not centrally located in the transverse web 4, but in the head parts 40, 41.

FIGS. 4a to 4c show a latching element 3. It essentially has one rectangular base body 30, which open towards the gutter inside and this opening is provided with a circumferential collar 31. The collar 31 serves as Stop when clicking the latching element 3 in the frame 2.

The latching element 3 has a bottom 32, a ceiling 33 extending parallel thereto, a rear wall 34 and two side walls 35, 36. A first side wall 35 extends perpendicular to the rear wall 34, the second side wall 36 extends in an acute Angle thereto, however, like the first side wall 35 is vertically aligned. The floor 32 runs over the width of the rear wall 34 flat and horizontal. About the width of the second Side wall 36, however, he is inclined, with his lowest point P on his front, the gutter inside facing, corner of the side wall 36 has. This is best seen in Figure 4b. This second oblique side wall 36 and the inclined Section of the bottom 32 serve as a guide for facilitated introduction of the crosspiece 4 in the latching element 3rd

Looking again at Figure 1, it can be seen how the inventive Cross bar 4 can be mounted in a simple manner. He is turning D is screwed into two opposing latching elements 3, wherein the tongues 43, 44 while the front side 40 ', 41' of the head parts 40, 41 are pressed, but no resistance Afford. When screwing into the latching elements 3 and the headboards 40, 41 compressed, which is made possible by the slots 45, 46. The final position is reached when the head parts 40, 41 on the horizontal areas of the floor 32 are located. In this position, the crossbar is spring-loaded in the vertical direction thanks to the compressed slots 45, 46 fixed by being form-fitting between the ceiling 33 and bottom 32 of the latching elements 3 is held. The first Side wall 36 prevents further rotation of the cross bar 4 beyond this position. Turning back in the opposite direction is prevented by the tongues 43, 44, so that the crossbar 4 is fixed against rotation. In this position, the cover grille can now be Place on the gutter and by means of the expansion clamps described above screwless in the crossbar. The chosen type of fixation is also relative Insensitive to manufacturing tolerances, so that wider or narrower Gullies can be provided with the same parts.

Instead of this embodiment, an embodiment according to the Use figures 5-7. In this case, the spring element is not on the cross bar. 4 but arranged in the latching element 3. The crossbar 4 itself preferably has a rounded end face 40 ', 41' on which a facilitated introduction into the latching elements 3 allows. As can be seen in Figures 5 and 6a, but also has this cross bar 4 via the through holes 47 in the head parts 40, 41 to the To accommodate expansion clips for attaching the cover.

FIGS. 8a to 8e show yet another embodiment. Here is the crosspiece 4 is not screwed but before the casting of the frame 2 in horizontal Direction inserted into the insert element 3. The latching element 3 and the head part 40, 41 of the cross bar 4 have teeth 37, 5, which is a horizontal displacement within the latch member 3, but allow a vertical displacement of the crosspiece 4 prevent. This embodiment has the advantage that manufacturing tolerances thanks to the horizontal shift can be optimally compensated. The cross bar 4 itself in turn has in its head parts 40, 41 passage openings 40 ', 41' to receive expansion clips 7. The head part 40, 41 can, but must not be closed to the bridge 42 out. This also applies to the other examples above. The expansion clamp 7 is in this embodiment formed as a bracket 70 with it on both sides arranged Spreizbeinen 71. These Spreizklammer 7 is placed over the cover. However, it is also possible on everyone Side of the gutter to use separate expansion clips 7, which has a head and thereon having arranged legs, as described in EP-A-0'931'885.

The drainage channel according to the invention thus has a securing device for Securing a cover on a gutter body, which is simple and inexpensive can be produced and which compensates for manufacturing tolerances.
