Definitions
- the invention relates to a safety device for a drainage channel according to the preamble of claim 1 and a cross member and a locking bracket for such a safety device.
- a securing device for a drainage channel is known from DE 42 41 707, in which a crossbeam with its ends can be inserted into recesses which are located in the inner side walls of a channel.
- the crossmember runs transversely to the longitudinal axis of the gutter in the interior of the gutter and comprises fastening devices for fastening a cover to the crossmember and thereby to the gutter.
- the crossbar described in DE 42 41 707 has a clamping device which is elastically deformable in such a way that it is deformed when inserted into the recesses in the channel by the movement of the crossbar in use.
- the clamping device consists of a clamping spring, which is either made of plastic or a stainless steel band.
- the geometry of the fastening device described in the publication requires a considerable amount of material, and in addition the flow cross section in flat channel systems is reduced.
- spring pressure is exerted on the side walls of the channel, which can impair its stability, in particular in the case of small sizes of the channel.
- an exact positioning of the traverse is difficult since, when inserting it, work must be carried out against the increasing spring force of the fastening device. If the position of the crossmember needs to be corrected, the force required to remove the crossmember from the recesses in the channel is even substantially higher than the force required to insert the crossmember.
- the object of the present invention is to provide a further developed safety device for a drainage channel in which, on the one hand, the material requirement is reduced and, on the other hand, a less expensive material can be used, the flow cross section in channel systems also not being significantly reduced.
- a further essential aspect of the present invention consists in the design of the blocking element as an exchangeable wedge-shaped blocking clip or spreading slide which is movably attached to the cross member or bracket. is that a change in position between an assembly and locking position is possible. Depending on the location - assembly or Locking state - the tab and the locking clip act here in a latching and / or clamping manner such that the locking clip has no activities for an intended one
- the tab can be manufactured inexpensively from stainless steel with a lower material use due to the advantageous geometry of the tab.
- the tab can also be made from another material that is inert to the flowing medium in the channel.
- This material can be, for example, a simple or passivated metal, wood or plastic, in particular hardened plastic.
- the blocking clip itself is preferably made of plastic.
- the tab can be made in one piece from a single material due to its simple geometry as a simple pressed part. The connection of several components or materials is not necessary.
- a recess is preferably provided in the tab, which is located essentially in the middle at the top of the tab in the installed state.
- the cover is preferably attached to the crossmember using the methods described in DE 42 41 706 and DE 42 41 707. These methods are a preferred embodiment, but other types of attachment, such as e.g. a lateral clasping of the traverse or tab are conceivable.
- Figure 1 is a plan view of a tab inserted and locked in a channel.
- Fig. 2 is a cross section of the built-in tab shown in Fig. 1 along the line II-II;
- FIG. 3 shows a cross section of the bracket installed in FIG. 1 along the line III-III;
- Fig. 4 is a side view of a locking clip
- FIG. 5 shows a plan view of a tab with a blocking clip in the mounting position and a counter-bearing cam
- Fig. 6 is another plan view of a tab
- Fig. 7 is a side view of the tab of Fig. 6 along the line VII-VII.
- FIG. 1 shows a section of a channel body which has recesses 12 in side inner walls, into which a tab 13 is inserted with its ends 14.
- the tab 13 is of elongated profiling and is locked at its opposite ends in each case with the aid of a blocking clip 15 on the side inner wall 11 of the channel body 10.
- the tab 13 has a fastening recess 16 which is arranged essentially in the middle of the top of the tab 13.
- the two locking clips 15 are each in their locking position.
- a wedge leg 17, which has a contact surface 18 and a bead 19, is arranged such that the contact surface 18 is in clamping contact with the side inner wall 11 of the channel body 10.
- the wedge leg 17 is here with the bead 19 and a wedge leg end portion 20 strongly tensioned against a locking leg 21, so that a clamping effect Kung between the contact surface 18 and the side inner wall 11 of the channel body 10 results.
- the blocking clip 15 it is guided through an opening which is located in the opposite longitudinal sides 23 of the profile 24, as can be seen in FIG. 2 and in FIG. 7.
- the opening 22 has a cross-sectional shape that essentially corresponds to the cross-sectional shape of the blocking clip 15.
- the clear width of the opening 22 essentially corresponds to the cross-sectional dimension of the tensioned or compressed blocking clamp 15.
- the blocking clip 15 is shaped so that it can be easily pressed into the opening 22 of the tab 13 with little effort, the wedge leg 17 being pressed slightly against its locking leg 21, so that the bead 19 and the wedge leg end section 20 against the locking leg 21 in Plant come. In this way, a clamping effect of the blocking clip 15 in the opening 22 is ensured.
- Blocking clip is essentially H-shaped. It has an elastically resilient central web 25, through which the opposite legs of the H-shape can be moved in their relative position to one another, and a wedge leg 17 with a first contact surface 18 and a bead 19, which is supported on an opposite locking leg 21, the Locking leg 21 has a first positioning stop 26 at one end and a second positioning stop 27 at another end.
- the wedge leg 17 has a wedge leg end section 20 which extends in the direction of the locking leg 21.
- the area of the locking leg opposite the wedge leg end section 20 has a sliding chamfer 28 which, in cooperation with the wedge leg end section 20, facilitates the pressing of the blocking clip 15 into the opening 22.
- kidney stop 26 located first notch 29 against a first opening inner edge 31 and thus fixes the blocking bracket 15 in its mounting position.
- the locking clip 15 When the locking clip 15 is moved into the locking position, the locking clip 15 slides through the opening 22 until a second notch 30 snaps against a second opening inner edge 32. By snapping the second opening inner edge 32 into the second notch 30 it is ensured that the blocking clip 15 is securely and immovably fixed in its locked position.
- the tab 13 To assemble the tab 13, it is accordingly first inserted into the recesses 12 of the side inner wall 11 of the channel body 10, the locking clips 15 being in their assembly position. After the tab 13 is correctly positioned, a tool, e.g. a hammer, a light impact on the striking surface 34 of the blocking clip 15, whereby the first opening inside edge 31 is knocked out of the first notch 29 over the nose 33, and the blocking clip 15 slides through the opening 22 until the second opening inside edge 32 over the opposite nose 33 slips and snaps into the second notch 30. The blocking clip 15 is now in its locking position.
- a tool e.g. a hammer
- kidney stop 27 a leg which extends the wedge leg and which has a second contact surface 35.
- the leg 36 and the wedge leg 17 are arranged at a somewhat obtuse angle with respect to the central web 25 than 90 °, so that the two legs 36 and 17 move away from the locking leg. If the second inner edge 32 of the opening now engages in the second notch 30, a clamping effect of the blocking clip 15 within the opening 22 is simultaneously caused by the increased distance of the leg 36 from the locking leg 21. This clamping effect prevents together with the nose 33 and that caused by the contact of the bead 19 and the wedge leg end section 20 against the locking leg 21
- the tab 13 has an opening 22 on each of its opposite longitudinal sides of the profile for receiving the blocking clip 15, so that the tab 13 can be fastened in the channel body 10 by locking two blocking clips 15.
- the tab 13 only has an opening 22 on one of the long sides 23 of the profile 24, while on the opposite side there is a counter bearing cam 37.
- This counter bearing cam 37 supplemented on the force side, the blocking clip 15 located on the other side of the tab 13.
- a tongue is punched out on one side or preferably on both sides of the ends 14 of the tab and bent so that it comes into contact with the side inner wall 11, which is adjacent to the recess 12 of the channel body 10, when the tab 13 in the channel body 10 is used.
- the tongues 38 are arranged at the level of an opening outer edge 39, so that it is ensured that the contact surface 18 of the blocking clip 15 can come into clamping action with the side inner wall 11 of the channel body 10. This is particularly clear from FIGS. 1, 3, 6 and 7.
- Fig. 2 it is clearly shown again how the blocking clip 15 is arranged in its locking position in the tab 13 through the openings 22.
- the wedge leg 17 is provided with a bevel 40 in the direction of its wedge leg end section 20, so that the wedge leg end section 20 in cooperation with the sliding chamfer 28 represents an insertion aid.
- the tab 13 is preferably designed in such a way that, in cooperation with the blocking clip 15, a coaxial stiffening of the channel body 10 results in the assembled state.
- a locking clip of the type described above is preferably used to fasten the tab 13 in the channel body 10, but the locking clip can also be designed as a rotary bolt, expansion bolt, latch bolt or spring bar.
- the locking clip remains captively connected to the tab, even if the tabs are removed for cleaning purposes of the channel body.
