Description

The invention relates to a height adjustment device for a drainage channel, in particular for the drainage of facades or patios, a drainage channel with a height adjustment device, a method for adjusting the height of a drainage channel and a grate locking device for a grate of a drainage channel.

Drainage channels for patios, balconies, flat roofs or facades are known from the prior art and are frequently used for roofs and balconies, in particular roof terraces. In contrast to conventional linear drainage, the water is not discharged along the channel run in the longitudinal direction, but through drainage slots across the channel onto the roof surface. The water is fed to a drain via the closed roof seal.

Height-adjustable drainage channels are also known in principle. These are often made of metal. The height adjustments of conventional drainage channels often use adjustable feet, the length or height of which can be adjusted via interlocking threaded rods and threaded receptacles. The height adjustment of a drainage channel may be necessary in order to compensate for local unevenness in the subsurface or to adjust the top of the drainage channel, in particular an overlying grate, flush with the surrounding floor covering.

Known height-adjustable drainage channels have the disadvantage that they are complex to install and the height is difficult or inaccurate to adjust. In addition, gutter systems made of metal are expensive to manufacture and are limited in terms of design options.

The object of the present invention is therefore to provide a height-adjustable drainage channel which is simple and quick to assemble and which is easily adjustable in height. In particular, the accuracy of the height adjustment is to be improved.

This object is achieved in each case by a height adjustment device according to claim 1 (aspect 1), a drainage channel according to claim 15 (aspect 15) and by a method for adjusting the height of a drainage channel according to claim 24 (aspect 24).

• ein sich entlang einer Verstellrichtung erstreckendes erstes Verstellelement, das im Stützkörper axial verschieblich gelagert ist und mindestens eine Auflagefläche für einen Rinnenkörper der Entwässerungsrinne aufweist,
• ein relativ zum Stützkörper in der Verstellrichtung festgelegtes zweites Verstellelement,
• ein Koppelelement, das zwischen einer Entkopplungsstellung, in der das erste Verstellelement und das zweite Verstellelement nicht miteinander gekoppelt sind, und einer Kopplungsstellung, in der das erste Verstellelement und das zweite Verstellelement miteinander gekoppelt sind, hin und her beweglich ist,
  wobei in der Koppelstellung das erste Verstellelement und das zweite Verstellelement über das Kopplungselement als Getriebe, insbesondere als Schraubgetriebe, zusammenwirken, insbesondere zur axialen Feinverstellung des ersten Verstellelements.

In particular, the object is achieved by a height adjustment device for a drainage channel, in particular for the drainage of facades or terraces, comprising a support body, in particular made of plastic, and at least one adjustment unit, the adjustment unit comprising:

• a first adjustment element extending along an adjustment direction, which is axially displaceably mounted in the support body and has at least one contact surface for a channel body of the drainage channel,
• a second adjustment element fixed in the adjustment direction relative to the support body,
• a coupling element which can be moved back and forth between a decoupling position in which the first adjusting element and the second adjusting element are not coupled to one another and a coupling position in which the first adjusting element and the second adjusting element are coupled to one another,
  wherein in the coupling position the first adjustment element and the second adjustment element interact via the coupling element as a gear, in particular as a screw gear, in particular for the axial fine adjustment of the first adjustment element.

An idea of the invention is to propose a height adjustment device for drainage channels, a rough adjustment and a

Fine adjustment of the height of the drainage channel allows. According to the invention, when the coupling element is in a decoupling position, a rough height adjustment (rough adjustment) takes place and, when the coupling element is in a coupling position, a finer height adjustment (fine adjustment or readjustment) can be carried out. In particular, in a first step, the height adjustment device is (manually) height-adjustable (can be lowered or raised) by (direct) force acting on the channel body, the first adjustment element being axially displaced. In a second step, a more precise (finer) height adjustment can be achieved by actuating the adjustment unit via a gear. The direction of adjustment can be understood as a height direction of the drainage channel, in particular a direction (vertical) up or down.

The fine adjustment takes place in particular via a transmission in which the first and the second adjustment element are kinematically coupled to one another via the coupling element. The first and the second adjusting element as well as the coupling element can have gear means such as threads or toothings which in particular mesh with one another. In particular, the first and the second adjustment element are supported against one another via the coupling element in the coupling position in the adjustment direction (axially). The first and the second adjusting element together with the coupling element in the coupling position form in particular a screw drive. In particular, the transmission converts a rotational movement of an adjusting element into an (axial) linear movement of the other or the same adjusting element.

A height adjustment device according to the invention has the advantage that it can be easily connected to a channel body, in particular by placing the channel body on the height adjustment device (from above). In addition, a simple and precise height adjustment is possible in a two-stage adjustment process (rough adjustment and fine adjustment).

In an advantageous development of the invention, the first adjustment element and / or the second adjustment element, in particular about longitudinal axes running in the adjustment direction, are rotatably mounted in the support body. As a result, the adjusting unit can be actuated via a rotary movement of the first and / or second adjusting element, for example by means of a screwdriver by the fitter.

In an advantageous development of the invention, the coupling element has first gear means, in particular an internal thread, and the first adjusting element or the second adjusting element has second gear means, in particular an external thread, wherein in the coupling position, first gear means and second gear means mesh with one another. In addition to threads, gear means can also use gears.

In an advantageous development of the invention, the coupling element is made in one piece with the first adjusting element or the second adjusting element, in particular as a radial projection which has an internal thread at least in sections on a threaded surface. The thread surface can be in the form of a half nut or by any peripheral section of a thread. In a one-piece design, the coupling element can be moved from the coupling position into the decoupling position and vice versa by movement (actuation), in particular twisting, of the first or second adjustment element.

In an advantageous development of the invention, the support body forms a receiving structure which extends in the adjustment direction and in which the adjusting unit is received, the receiving structure in particular forming a longitudinal guide for the first adjusting element. The receiving structure in particular forms a cylindrical cavity into which the first and the second adjusting element (from above) can be inserted. A receiving structure can be molded onto a support body made of plastic, or it can be attached as a separate component to a base plate of the support body, in particular inserted therein.

In an advantageous development of the invention, the first adjusting element has a first longitudinal groove for locking the coupling element in the coupling position and preferably a second longitudinal groove for locking the coupling element in the decoupling position, the receiving structure in particular a locking projection for engaging in the first longitudinal groove or second longitudinal groove having. A lock can be understood to mean an anti-twist device that can be released against a resistance that can be overcome (by rotating the adjusting element). The first longitudinal groove has the advantage that the first adjustment element is held in a defined decoupled (free) position during the height adjustment and does not hinder the height adjustment process (rough adjustment). Second Longitudinal groove has the advantage that the coupling element is held firmly in the coupling position in order to ensure that the gear means interact. Longitudinal notes prevent the first adjustment element from being inadvertently rotated relative to the receiving structure. The locking projection can be designed as a rib, in particular as a bendable longitudinal rib.

In an advantageous development of the invention, the second adjusting element has a circumferential groove, in which an at least partially circumferential collar section formed by the receiving structure engages in particular. The second adjusting element is axially fixed via a circumferential groove, but is rotatably mounted in the receiving structure about its longitudinal axis. The collar section is in particular an inwardly projecting edge of the receiving structure.

In an advantageous development of the invention, the first adjusting element and / or the second adjusting element has an engagement profile at the end for rotating the first or second adjusting element, in particular from the side of the channel body. The first and / or second adjustment element can be rotated through the engagement profile, for example a transverse slot, hexagon socket, square or the like, in particular from above about the respective longitudinal axis.

In an advantageous development of the invention, the support body has two opposing, in particular identically designed, receiving structures, in each of which an adjusting unit is accommodated. In particular, the height adjustment device is constructed point-symmetrically to a center point of the support element, the adjustment units in particular being constructed identically. As a result, a height adjustment device can be mounted on a channel body in both possible transverse orientations.

In an advantageous development of the invention, at least one spring acting in the adjustment direction, in particular helical spring, is accommodated in the support body, which is preferably connected to a base plate of the support body by means of latching lugs, in particular for supporting the channel body while the coupling element is in the decoupling position. A spring causes the underside of the channel body to be supported by the spring force during the rough adjustment. When the coupling element is in the decoupling position or when the adjusting unit is set to a sufficiently low height, the channel body can (manually) counter to the spring force Press the direction of the support body into a desired height position (rough adjustment). This enables a simplified installation of the gutter system, since the fitter, especially when aligning the entire gutter strand, does not have to lift the entire gutter strand (several interconnected gutter bodies) against gravity, but only slightly (manually) push the gutter strand down due to the spring forces to achieve the rough adjustment. This is a significant relief for the fitter on the construction site. The fitter can use an adjacent floor covering (e.g. slabs or tiles) by placing an alignment tool (ruler, wooden slat, etc.) as a height stop for the rough adjustment of the channel run. The required height (fine) can be set using the height adjustment device.

In an advantageous development of the invention, the first adjusting element has at least one fastening element, in particular latching elements, for detachable, preferably non-rotating connection to the channel body, in particular the edge of a through opening of the receiving dome of the channel body, at an upper end. Fastening elements are preferably provided on both sides, which are in particular in the form of clip connectors (beveled at the top).

In an advantageous development of the invention, the support body has lateral guide columns for receiving in corresponding guide receptacles of the channel body, the guide columns in particular having latching lugs for releasable latching with corresponding openings (latching openings) in the channel body. The locking lugs allow the height adjustment device to be fixed to the channel body despite the spring force acting, for example for transport.

In an advantageous development of the invention, a base plate of the support body has receiving openings for coupling, preferably latching, of elevation elements on the underside of the support body. Additional elevation elements achieve height adjustability by defined height levels that exceed the adjustment range of the height adjustment device.

In an advantageous development of the invention, at least one elevation element, optionally a plurality of elevation elements, is / are stacked one above the other connected together, coupled to the underside of the support body. Such an embodiment enables a large height adjustment of a drainage channel. In particular, one elevation element each has at least one, preferably conically shaped, support element. In addition, at least one latching element can be provided that can be connected in one piece to a support element. (Vertical) forces acting on the support body in the subsurface can be dissipated via support elements, while latching elements prevent the elevation element or the support body above it from being lifted off. The crash elements have the function of spacers that specify a defined height difference.

The stated object is also achieved in particular by a drainage channel, in particular for the drainage of facades or terraces, comprising a channel body, in particular made of plastic, which forms at least one receiving dome open towards the underside of the channel body, and a height adjustment device according to the invention, the adjustment unit of the height adjustment device, in particular a receiving structure of the support body, in which the receiving dome is received and the channel body can be supported on the at least one bearing surface of the first adjusting element.

A receiving dome can be understood to mean a cavity that is open on one side. Recording domes can be integrated, preferably molded, in a predetermined grid, in particular on both sides of the channel. The channel body of a drainage channel according to the invention, in particular a facade channel, can either be used with a fixed overall height, or can be made height-adjustable (in sections) by (locally) attaching height-adjusting devices according to the invention. In particular, a height adjustment device does not have to be accommodated in every receiving dome or in each pair of opposing receiving domes.

In an advantageous development of the invention, the receiving dome has a through opening for actuating the adjustment unit, in particular by rotating the first adjustment element and / or the second adjustment element. The through opening in particular enables access (from above) to the Engagement profiles of the first and / or second adjustment elements, in particular in order to actuate them by means of a screwdriver.

In an advantageous development of the invention, the channel body has guide receptacles on the underside for receiving corresponding guide columns of the support body of the height adjustment device. In particular, the channel body has openings for immersing corresponding locking lugs of the guide columns. In addition, the openings can be used to increase the adjustment path and / or to avoid collisions between the channel body and the height adjustment device.

In an advantageous development of the invention, the channel body has spring receptacles on the underside for receiving upper ends of the springs accommodated in the support body. As a result, springs are loaded as axially as possible during the rough adjustment.

In an advantageous development of the invention, the channel body has a plurality of drain slots, in particular running in a transverse direction of the channel body, which are separated from one another via breakable material webs of the channel body, the material webs in particular having material thinnings at the web ends. Material thinning can be designed as tapers or local cross-section thinning and serve to form predetermined breaking points (separable material webs). By breaking out material webs, several drainage slots can be connected to a (larger) opening, for example to enable the connection of a (lateral) puncture channel to the channel body.

In addition, knock-out areas can be provided in the channel bottom, which enable the channel to be connected to local drainage pipes. Such stripping areas can also be provided by material thinning or separable material webs. For example, an eccentric plug-in connector can be used to connect a tube to the channel body in order to connect a tube to the channel body.

In an advantageous development of the invention, the channel body has end-side sliding / latching devices for connection to an adjacent channel body, in particular downwards or in the longitudinal direction of the channel body aligned locking lugs for engaging in corresponding recesses of the adjacent channel body. Such sliding / locking devices serve to compensate for temperature and material-related linear expansion of channels. In this way, stresses between two channel bodies of a channel strand can be absorbed or avoided. In particular in the case of a large number of channel bodies arranged one behind the other (channel run), the temperature-related linear expansions add up and can lead to faults in the channel run. This can lead to failure of the entire gutter system. A sliding / latching device enables a defined zero position, from which movements in both directions are possible. A channel body can be locked from above and / or in the longitudinal direction with an adjacent channel body.

A plurality of receptacles for threaded nuts can be arranged on the underside of the channel body. The recordings have an opening through which screws can be inserted. A grate can be screwed to the channel body using the screws.

In an advantageous development of the invention, a height-adjustable end wall is attached to an end face of the channel body, the end wall being in particular made in two parts, in particular a first end wall part being firmly connected to the channel body and a second end wall part adjustable in height via elongated holes to the first end wall part. A first end wall part can be connected to the channel body in particular via clamping elements or a clamping connection. A height-adjustable end wall can have a supporting effect in order to ensure the load-bearing capacity of the channel body at the channel end, in particular when the channel is cut to any desired length. A height-adjustable end wall can preferably be plugged onto a channel end, in particular via (lateral) clamping elements. A height-adjustable end wall is provided in a (continuous) channel run, in particular only at one or both ends of the channel run. The front wall can act as a support foot at any position, especially after shortening (cutting) the channel body.

In an advantageous development of the invention, the channel body forms opposing channel frames, each of which faces the interior of the Form gutter body extending spring elements. The grate can be centered by such spring elements, wherein in particular an approximately the same gap dimension is achieved on both sides of the gutter. In this respect, the spring elements can act as grate centering.

In an advantageous development of the invention, a channel frame has a locking recess, which is designed for an engagement of a blocking section of a grate locking device inserted into a grate. In the area of the channel bottom, additional receiving devices can be provided for receiving a grate lock, in particular receiving openings for threaded nuts, via which a grate can be screwed to the channel body.

A connection adapter, preferably made of sheet metal, can be fixed to the channel body for the connection of further accessories, such as a reveal drainage element. This connection adapter is attached to the channel body in particular via a positive connection.

4. d) Fine adjustment of the height of the channel body while a coupling element is in the coupling position by actuating the adjusting unit, in particular by rotating the first adjusting element or the second adjusting element.

The method has advantages similar to those already described in connection with the height adjustment device according to the invention and the drainage channel. The method can implement some or all of the procedural features that have been described in connection with the height adjustment device and the drainage channel.

Another object of the invention is to provide a grate locking device which on the one hand prevents the grate from being inadvertently lifted out of the channel body and on the other hand enables the grate to be lifted out easily if this is intended.

This object is achieved by a grate locking device according to claim 25 (aspect 25).

• ein Gehäuse zum Einsetzen in mindestens eine Masche des Rosts, wobei das Gehäuse eine Seitenausnehmung aufweist;
• eine in dem Gehäuse um eine Querachse schwenkbar gelagerte Betätigungswippe, die auf einer Seite einen Druckabschnitt und auf der anderen Seite einen Zugabschnitt aufweist,

In particular, the object is achieved by a grate locking device for a grate of a drainage channel, in particular a drainage channel according to the invention, comprising

• a housing for insertion into at least one mesh of the grate, the housing having a side recess;
• an actuating rocker pivotally mounted in the housing about a transverse axis, which has a pressure section on one side and a pull section on the other side,
  wherein the pressure section on a bottom forms a support lever for supporting the actuating rocker against a channel body and the Pull section on an underside has an unlocking section and a locking section;
• a locking rocker pivotally mounted in the housing about a vertical axis, which has a locking section and an unlocking section which, when the operating rocker is pivoted, cooperate with the locking section or the unlocking section of the operating rocker in such a way that a blocking section of the locking rocker for locking the grate with the channel body the side recess can be pivoted through for engaging in a locking recess of the channel body or for unlocking the grate from the locking recess.

The components of the grate locking device, in particular the housing, the operating rocker and the locking rocker, can be made of plastic. The grate locking device is particularly suitable for use in stainless steel or galvanized steel mesh gratings.

A grate locking device according to the invention has the advantage that the grate lifts up automatically (automatically) from the channel body when it is unlocked, in particular by means of a support via the support lever. If grate locking devices according to the invention (only) are provided on one side of a drainage channel, the grate automatically rises on this side when unlocked and can be easily removed from the channel body. In addition, when a grate is gripped by dirt or is otherwise jammed with the channel body, there is also the risk of also lifting the channel body, since the channel body is typically not fixed on the substrate. This can be prevented by automatically lifting the grate during unlocking by means of a grate locking device according to the invention.

In this way, the support rod is at least partially enclosed by the grate locking device. When the grate is raised by pulling on the pull section of the operating rocker (in the fully unlocked state), the grate is also lifted.

In an advantageous development of the invention, an upper side of the pressure section and the pull section does not protrude beyond the upper side of the grate in a locked state, and in particular is flush with the upper side of the grate.

In an advantageous development of the invention, the support lever forms a curved, in particular convex, support surface for support against the channel body. This results in a steady or even lever movement of the grate.

The unlocking and locking sections are in particular designed as projections or as pins. The unlocking and the locking section of the actuating rocker are preferably formed in one plane, in particular essentially oriented perpendicular to one another. The actuating rocker is in particular rotatably mounted on both sides in, preferably identically designed, housing halves. The locking rocker is preferably clipped onto a strut running in the vertical direction, which in particular delimits or divides the side recess.

In an advantageous development of a drainage channel according to the invention, a grate is inserted into the channel body, at least one grate locking device according to the invention being inserted on one grate side, and in particular at least one locking hook of the grate in a locking recess of the grate side on the other grate side Channel body engages. By installing the grate locking devices according to the invention on only one side, the grate can be automatically lifted on one side.

In the following description of the invention, the same reference numerals are used for identical and identically acting elements.

The Fig. 1A , 1B , 2A and 2B show a height adjustment device 1 according to the invention, which has a support body 10 made of plastic and two adjustment units 80 arranged on both sides. The adjustment direction V runs in the height direction of the height adjustment device 1 or a drainage channel 100 (see, for example Fig. 4 ). Each adjusting unit 80 is accommodated in a receiving structure 12 of the support body 10 and has a first adjusting element 21, a second adjusting element 22 and a coupling element 23. The first adjusting element 21 has two contact surfaces 210 for a channel body 2 on an upper side. In a base plate 11 of the support body 10 springs 14 are received, which are designed here as coil springs. At the corners of the base plate 11, four guide columns 13 are provided, which guide a channel body 2 placed on the height adjustment device 1 in the longitudinal and transverse directions (column guide), a certain clearance being permitted. The guide columns 13 have curved stop surfaces 18, the shape of which is adapted to the underside of the channel body 2. The channel body 2 can be detachably connected to the support body 10 against the spring force of the springs 14 by means of latching lugs 16 engaging in openings 56 of the channel body 2. In the base plate 11 there are receiving openings 17 for coupling additional elevation elements 40 (see Figure 3A and 3B ) intended.

A height adjustment of a channel body 2 of a drainage channel 100 is possible in succession in two steps using the height adjustment device 1 according to the invention, a rough adjustment being possible in a first step and a fine adjustment being possible in a second step. The first adjusting element 21, the second adjusting element 22 and the coupling element 23 act together as a gear 20 for fine adjustment, the function of which will be described below.

The first adjusting element 21 is inserted into the receiving structure 12 of the support body 10 and is axially displaceably mounted in the receiving structure 12 along the adjusting direction V. A coupling element 23 in the form of a radial projection is connected in one piece to the first adjusting element 21. The coupling element 23 has an internal thread on a threaded surface 231, which represents the first gear means 24. The second adjusting element 22 is designed here as a screw with an external thread, which represents the second gear means 25. The second adjustment element 22 is inserted into the correspondingly shaped receiving structure 12. In its upper region, the first adjusting element 21 has a circumferential circumferential groove 221 which is in a engages corresponding collar section 121 of the receiving structure 12. In this way, the second adjusting element 22 (screw) is axially fixed but rotatably mounted, ie the screw does not turn up or down (adjustment direction V) despite rotation, despite its thread pitch, but remains axially stationary. The first and the second adjustment element 21 and 22 can be brought into engagement with one another via the coupling element 23, so that the adjustment elements 21, 22 are supported against each other in the adjustment direction V (axially) and are kinematically coupled to one another via the screw drive formed. A rotation of the second adjustment element in the coupling position causes a translatory axial displacement of the first adjustment element 21 in the adjustment direction V.

The adjusting element 21 can be rotated back and forth between a coupling and a decoupling position Figure 2A respectively. Figure 2B are posed. The adjusting element 21 has two grooves running parallel in the longitudinal direction, namely the first longitudinal groove 211 and the second longitudinal groove 212. The receiving structure 12 forms a corresponding latching projection 122, here embodied as a longitudinal rib, which can at least partially engage in the first longitudinal groove 211 or the second longitudinal groove 212. This intervention does not achieve a fixed fixation, but only creates a resistance that can be overcome. By engaging in the second longitudinal groove 212, the first adjustment element 21 is held in a defined decoupling position when the channel body 2 is adjusted in height and does not interfere with the height adjustment process (rough adjustment). By engaging in the first longitudinal groove 211, the adjusting element 21 is held securely in position when the second adjusting element 22 is rotated (screw for fine adjustment) during fine height adjustment. The fine adjustment of the height level of the channel body 2 takes place via the rotation of the second adjusting element 22, which brings about an axial fine displacement of the first adjusting element 21. The channel body 2 lies with the underside on the support surface 210. The first adjusting element 21 and the second adjusting element 22 are positively coupled to one another in the coupling position and act together as a gear (screw drive). In the coupling position, positive locking also prevents the first and / or second adjusting element 21 or 22 from being lost during transport.

The springs 14 are connected to the base plate 11 via locking lugs 19 and raise the channel body 2 in the decoupling position of the coupling element 23 to a maximum height position. The channel body 2 is pressed down for example, by the mechanic's strength. This rough positioning (rough adjustment) is secured by locking the first locking element 21 by rotating the coupling element 23 into the coupling position. Then the fine adjustment is made to the desired height level at least to the millimeter. The first adjusting element 21 has fastening elements 213 in its upper region for connection to the channel body 2. This connection does not hinder rotation of the first adjusting element of FIG. 21.

In order to be able to extend the entire height of a drainage channel 100 by the adjustment range of the adjustment unit 80, one or more elevation elements 40 can be locked under the base plate 11 of the height adjustment device 1, as in FIG Figure 3A and 3B posed. The base plate 11 of the support body 10 has receiving openings 17 coupling of crash elements 41. In addition, latching elements 42 are provided which engage in lateral recesses in the receiving openings 17. Raising elements 40 have four conical support elements 41 which transmit the loads absorbed by the channel body 2 directly to the ground. In the embodiment according to Figure 3A and 3B two elevation elements 40 stacked one above the other are connected to the support body 10.

Fig. 4 shows a drainage channel 100 according to the invention with a channel body 2 made of plastic, in which several in connection with the Figures 1A to 2B described height adjustment devices 1 are included. The channel body 2 forms a plurality of receiving domes 53 which are spaced apart from one another in a grid and which are open towards the underside of the channel body 2. The holding domes 53 are provided for holding an adjusting unit 80 or a holding structure 12. Below the channel frames 57, guide receptacles 55 are provided for receiving the guide columns 13 of the height adjustment device 1. In addition, 2 receptacles for the springs 14 are provided on the underside of the channel body. Spring elements 59 in the form of inwardly projecting plastic leaf springs for centering an insertable grate 4 are arranged in the channel frames 57 on both sides.

A height adjustment device 1 can be installed on site in a prefabricated receiving dome 53. Alternatively, the drainage channel 100 can be delivered to the construction site fully pre-assembled. This makes it possible to have a corresponding number of different loads Height adjustment device to be provided in FIG. 1 in order to be able to meet the required load requirements or to be able to react to changed load requirements. By using latching or clip connections in the form of latching lugs 16, the height adjustment device 1 can be detached from the channel body 2 and inserted into another pair of receiving domes 53. This makes it possible to cut the drainage channel 100 to length on the construction site in order to adapt it to the local conditions.

The second adjusting element 22 and the first adjusting element 21, in particular their engagement profiles 26 formed at the end, are accessible by means of a screwdriver through the through openings 54 on the upper sides of the receiving domes 53 in a grate support surface 75 of the channel body 2. By turning the first adjustment element 21, the adjustment unit 80 can be switched back and forth between the coupling and the decoupling position, in which the axial mobility of the first adjustment element 21 for coarse height adjustment or presetting is blocked or released. A fine height adjustment or readjustment can be achieved by rotating the second adjustment element 22.

In Figure 5A a section of the channel body 2 is shown with transversely extending drain slots 51, which are separated from one another via breakable material webs 52. The material webs 52 have material thinnings 50 on the webs that define predetermined breaking points. By breaking out individual material webs 52, an enlarged opening in the channel body 2 can be created for connecting further components. Additional circular stripping aids are provided in the channel bottom 58 for connecting the channel body 2 to local drainage pipes.

Figure 5B illustrates the functioning of the height adjustment device 1 according to the invention already described in connection with a channel body 2 and a grate 4 inserted therein.

In the 6A and 6B a drainage channel 100 is shown with a height-adjustable end wall 60 made of sheet metal. The two-part end wall 60 has a first end wall part 61 and a second end wall part 62 with elongated holes 63, both end wall parts 61, 62 being produced as sheet metal parts and being connected to one another via screw connections 64. To ensure the load-bearing capacity at the end of the channel when the channel body is cut to length 2 at any point, the height-adjustable end wall 60 can be attached with a support effect. The end wall part 61 is fixed via clamping elements 65 at the cut-off point of the channel. The second end wall part 62 has an L shape and supports the first end wall part 61. The height of the end wall 60 can be changed continuously via the elongated holes 63 when the screw connections 64 are loosened. If the channel body 2 is used without a height adjustment device 1, only the first end wall part 61 is to be used. When using elevation elements 40, the second end wall part 62 shown can be replaced by a longer L-plate in order to ensure a supporting effect of the channel body 2.

In the 7A, 7B and 7C A connection adapter 71 made of sheet metal is shown, which is used to connect further accessories, such as a reveal drain element. The connection adapter 71 has an adapter opening 74 and is fastened to the channel body 2 via a positive connection, namely via support pins 72 and guide tabs 73 formed on the channel body 2.

In the 8 to 13 is a grate locking device 3 according to the invention made of plastic for a grate 4 of a drainage channel 100, the operation of which is described below. The grate locking device 3 is inserted from above into the grate between two meshes of a grate 4 made of steel. The grate locking device 3 is positively fixed to a support rod 90 and / or filler rod of the grate 4 by means of latching hooks. The grate locking device does not protrude up or down from the grate 4 in the closed state.

The grate locking device 3 consists of a housing 30 with two identical housing halves, the operating rocker 31 and the locking rocker 35. The housing 30 has a side recess 301 through which the blocking section 36 protrudes laterally in the locked state and dips into a locking recess 70 in the channel frame 57 or intervenes in this. The shape of the operating rocker 31 prevents the locking rocker 35 from rotating and the blocking section 36 from moving into the grate 4. Two grate locking devices 3 are typically installed on one side per meter of grate 4. On the opposite side of the grate, immovable locking hooks or latches protrude from the grate protrude into corresponding locking recesses 70 of the channel body 2. In this way, the grate 4 is secured against unintentional lifting.

The actuating rocker 31 is pivotally mounted in the housing 30 about a transverse axis Q and has a pressure section 32 on one side and a pull section 33 on the other side. The pressure section 32 has a support lever 34 on the underside in order to be able to be supported against the channel body 2 when the actuating rocker 31 is actuated to lever out the grate 4 from the channel body 2. The pull section 33 forms an unlocking section 33a and a locking section 33b on the underside. The locking rocker 35 is pivotally mounted in the housing 30 about the height axis H and has a locking section 35b and an unlocking section 35a. When the operating rocker 31 is pivoted to lock, the locking section 33b of the operating rocker 31 interacts with the locking section 35b of the locking rocker 35. When the operating rocker 31 is pivoted for unlocking, the unlocking section 33a of the operating rocker 31 interacts with the unlocking section 35a of the locking rocker 35. In the locked state, the blocking section 36 of the locking rocker 35 engages through the side recess 301 and the side recess 91 of the grate 4 into a locking recess 70 of the channel body 2 and prevents the rack 4 from being lifted out of the channel body 2. The bevelled and oppositely aligned contact surfaces 37a and 37b of the locking rocker 35 slidably cooperate with the unlocking section 33a and the locking section 33b of the actuating rocker 31 at contact points in order to generate an opposite pivoting direction of the locking rocker 35.

The housing 30 has a receiving slot 38, which is open at the bottom, for receiving a supporting rod 90 of the grate 4. The support lever 34 forms a grate lifting surface 39a which pivots over the receiving slot 38 when the actuating rocker 31 is pivoted and in this way engages under or encloses the support rod 90 received in the receiving slot 38. In this way, the grate 4 can be lifted out of the channel body 2 via the grate locking device 3 in the unlocked state. If the actuating rocker 31 is rotated by pressing the pressure section 32 and then pulling the pull section 33, which is only possible in one direction, the locking rocker 35 rotates such that the blocking section 36 moves into the grate 4. As in the Figure 12A is turned off, the blocking locking section 33b is moved away for this purpose and the unlocking section 33a of the actuating rocker 31 presses against the obliquely shaped contact surface 37a of the unlocking section 35a of the locking rocker 35, which leads to that in FIG Figure 12A shown pivotal movement leads. As a result, the blocking section 36 is moved out of the locking recess 70, as a result of which the grate 4 is no longer secured against lifting out.

When the actuating rocker 31 is further rotated by pulling the pull section 33, the support lever 34 presses with the curved support surface 39b against the grate support surface 75 of the channel body 2 and lifts the grate 4 out of the channel on one side, as in FIG Fig. 13 shown. The open or unlocked position of the grate locking device 3 is in the 10A and 10B shown. One advantage of lifting the grate 4 on one side is that the grate 4 can also be removed at installation locations in which, for example, the facade partially projects beyond an inside of the gutter. The grate 4 can be lifted out of the channel body 2 by pulling on the actuating rocker 31, more precisely on the pull section 33. The grate lifting surface 39a of a rib of the actuating rocker 31 engages under the support rod 90, thereby preventing the grate locking device 3 from being released from the grate 4 by the force of the lifting process.

If the grate 4 with the grate locking device 3 is inserted into the channel body 2 and the actuating rocker 31 is rotated in the opposite direction to the previously described rotational movement, the grate automatically lowers on the grate support surface 75 of the channel body 2. The actuating rocker 31 presses one at the end of the rotational movement inclined contact surface 37b of the locking rocker 35, whereby the locking rocker 35 moves back into the locking position. At the end of the rotational movement, the blocking section 36 engages in the locking recess 70 of the channel frame 57 and secures the grate 4 against lifting out.

The rotational movements and the contact points (see circles) when unlocking ( Figure 12A ) and when locking ( Figure 12B ) are shown in the drawing.

In the 14A and 14B the underside of the channel body 2 is shown. Spring receptacles 78 for receiving upper ends of the springs 14 accommodated in the support body 10 and receiving openings 77 for threaded nuts are shown. Screws can be inserted into the receiving opening 77 in order to screw the grate 4 to the channel body 2. Sliding / locking devices 76 are provided at the end of the channel body 2 for connecting adjacent channel bodies 2 to form a channel line and for length compensation of temperature-related changes in length.
