Definitions

• the present invention relates to a channel element with a channel body, on the side walls of which locking means are provided, and a cover which is held lockably on the channel body.
• a drainage channel in which a grating can be pivoted into a supporting frame and is provided with securing means on the side opposite the pivot axis.
• the securing means comprise an external thickening which engages in a pocket on the support frame.
• Other means of security can also be provided.
• This channel element is easy to assemble, but the grate and the support frame can never be manufactured so precisely that the grate is held in the support frame without play. This causes rattling noises and increased wear and tear when the grate is passed over.
• the type of locking provides a positive and non-positive connection so that the cover forms a unit with the channel body and annoying rattling noises are avoided when the cover is passed over.
• the guide surface and a surface on a side wall against which the locking slide rests are inclined to one another.
• the surfaces of the locking slide, which bear against the cover and the side wall can be inclined to one another.
• the locking slide In the open position, the locking slide preferably protrudes at least partially over the cover of the channel body. This makes it easy to see during assembly whether the locking means are already in engagement with the channel body or whether locking still needs to be carried out.
• the locking means Preferably, the locking means must be pressed down during the locking process so that the locking can also take place automatically, for example when the cover is run over and the locking means is thereby pressed down.
• At least one spring-loaded locking slide is provided for the positive locking.
• This locking slide forms a movable link between the cover to be fixed and the fixed channel body.
• Each locking slide is preferably from an open, projecting position can be snapped into the closed position by loading from above, for example by running over the cover. This allows the locking slide to be closed without tools.
• Each locking slide is preferably biased towards the side wall in the closed position by means of a spring and lies against a clamping point on the cover and engages with a retaining lug in the side wall.
• the cover is held on the side wall by means of clamping forces, the locking slide being clamped on the one hand to the side wall and, on the other hand, resting on the cover at a clergy point.
• the latching slide comprises a retaining lug which bears against an insertion slope of the side wall which is inclined horizontally.
• the insertion bevel is expediently curved downward from the inside of the channel body, so that the adjustment path of the locking slide from the open position into a closed non-positive Position reduced.
• the maximum adjustment path of the locking slide to compensate for manufacturing tolerances would have to be greater than if the insertion slope were curved.
• the area on the cover is preferably formed essentially perpendicular to the insertion slope in the area of the clamping point between the locking slide and cover.
• the cover For simple assembly of the cover, it can preferably be pivoted onto the side walls of the channel body.
• the channel body can be mirror-symmetrical, so that the cover can be mounted from both sides.
• a nose is formed on the cover on the side opposite the latching slides and is at least partially encompassed by a holding part connected to the side wall.

• a channel element 1 comprises a channel body 2 made of a concrete material, which has a U-shaped inner section and a rectangular outer cross section.
• the channel body 2 is formed integrally with a side wall 3 and a side wall 4.
• a holding part 5 made of metal is provided, which is firmly connected to the side wall 3.
• a holding part 6 is provided, which is constructed identically to the holding part 5.
• the sectional view through the channel body 2 in FIG. 1 runs as shown in FIG. 5 with the line x-x.
• the channel body 2 is closed with a cover 8, which has at least one nose 7, which is partially encompassed by the holding part 5.
• two locking slides 9 are provided over the length and are pressed by means of a leaf spring 10 in the direction of the side wall 4 (to the left in FIG. 1).
• the latching slide 9 lies with its widened head 16 in the closed position on lateral guide surfaces. Chen 20 at a terminal point 12 on the cover 8. Furthermore, the locking slide 9 is provided in the lower region with a holding lug 13 which engages in a pocket 18 in the holding part 6. In the pocket 18, an insertion bevel 14 is formed, which is curved slightly downward. The holding nose 13 lies with the tip on the insertion slope 14. The locking slide 9 thus presses the cover 8 against the holding part 6.
• the locking slide 9 is also provided with a projection 15 which bears against a stop 17 on the cover 8 when the locking slide 9 is in the open position.
• the locking slide 9 closes at the top with a rounded surface 16, which protrudes beyond the cover 8 in the open position.
• the spring 10 is designed as a leaf spring and bears against the locking slide 9 with a rounding 11.
• the locking slide 9 is provided with a projection 22 so that the spring 10 is captively received between the cover 8 and the locking slide 9.
• the side walls 3 and 4 are mirror-symmetrical, so that the cover 8 can be mounted on the channel body 2 from both sides.
• the assembly of the cover 8 and the opening of the cover 8 is described below.
• Fig.l the channel element 1 is shown with the cover 8 and the locking slide 9 in the closed position.
• the spring 10 presses the locking slide 9 against the clamping point 12 and in the region of the retaining lug 13 against the insertion bevel 14, so that the cover 8 is held on the channel body 2 in a force-locking manner. Due to the inclined insertion bevel 14, the locking slide 9 is pressed obliquely downward, so that a vertical force component is generated at the clamping point 12 in addition to the horizontal force component. As a result, the cover 8 is clamped onto the channel body 2.
• a tool engages in a gap 23 between the cover 8 and the locking slide 9 and lever the locking slide 9 obliquely upwards (angle arrow 26 in FIG. 1).
• the projection 15 on the locking slide 9 comes into contact with the stop 17 of the cover 8, so that the locking slide 9 of the open position is fixed by means of the clamping force of the spring 10.
• a projection 24 rests on the holding lug 13 on a section of the cover 8, so that the locking slide 9 cannot pivot.
• the cover 8 can be removed from the channel body 2 by pivoting the cover upwards (FIG. 3).
• the holding part 5 and the nose 7 specify the pivot axis.
• the locking slide 9 can be arranged in the open position (FIG. 2) and the cover 8 can be pivoted onto the channel body 2. Subsequently, the locking slide 9 only needs to be pushed down until the projection 24 on the retaining lug 13 comes out of the center of engagement of the cover and the locking slide 9 swings into the pocket 18 due to the spring force 10. As soon as the retaining lug 13 abuts the insertion bevel 14, clamping forces are formed due to the spring force, which hold the cover 8 non-positively on the channel body 2.
• the cover 8 can also be locked with the locking slide 9 in the closed position. Then the retaining lug 13 slides on an insertion oblique 19 of the holding part 6 and is brought into engagement with the pocket 18 in the manner of a snap connection. As a result, the cover 8 engages with the locking slide 9 in the closed position.
• the holding element 5 has three lugs 25 distributed over the length of the channel body 2, which hold the cover 8 on the side wall 3 on the side opposite the locking slide 9.
• a gap between the nose 7 and the holding member 5 is shown in FIGS. To 4 shown, but in most cases the finished from a Gußrost gebil- • cover 8 is formed slightly curved, so that the cover 8 in the central region of the nose 25 abuts while the cover 8 is seated on the holding part 5 in the lateral area below.
• the cover is only inserted into the holding element 5 on one side and then swiveled in. It is also possible to provide locking slides 9 on both sides of the cover.
• the cover 8 is preferably made of cast iron. However, it is also possible to design the cover 8 as a pressed sheet metal grate or a differently designed cover. In the The exemplary embodiment is the locking slide 9 made of metal and the spring 10 made of stainless steel. However, it is also possible to use other materials and to design the spring 10 as a plate or spiral spring.
• FIGS. 1 to 4 consists essentially of the design of the spring designated 10a, which is clamped here with its smooth leg 27 on the back of the locking slide between its head surface 16 and the rear lower projection 22, while the angled spring arch piece , in Fig. La designated 28, lies on a casting 29 of the cover 8a.
• This design has the advantage that any contamination occurring from above, the gap is designated 30 in the figures, between the spring 10a and the web 29 of the cover 8a does not lead to a functional impairment of the spring, but rather results from the movement over time the spring moved down.
