Description

The invention relates to a grate locking device for a grate of a drainage channel.

Drainage channels for terraces, balconies, flat roofs or facades are known from the prior art and are often used for roofs and balconies that are in use, in particular roof terraces. In contrast to conventional linear drainage, the water is not drained along the length of the channel, 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. Often these are 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 to compensate for local unevenness of the subsurface or to adjust the top of the drainage channel, in particular a grate on top, to be flush with the surrounding floor covering.

Known height-adjustable drainage channels have the disadvantage that they are complex to assemble and the height can only be adjusted with difficulty or inexactly. In addition, metal gutter systems are expensive to manufacture and limited in terms of design options.

It is advantageous to provide a height-adjustable drainage channel that is easy and quick to assemble and can be easily adjusted in height. In particular, the accuracy of the height adjustment should be improved.

• 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.Particularly advantageous is 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 mounted axially displaceably in the support body and has at least one bearing surface for a channel body of the drainage channel,
• a second adjustment element fixed relative to the support body in the adjustment direction,
• a coupling element that can be moved back and forth between a decoupling position in which the first adjustment element and the second adjustment element are not coupled to one another, and a coupling position in which the first adjustment element and the second adjustment element are coupled to one another,

wherein in the coupling position the first adjusting element and the second adjusting element interact via the coupling element as a gear, in particular as a helical gear, in particular for the axial fine adjustment of the first adjusting element.

One idea is to propose a height adjustment device for drainage channels that enables a coarse adjustment and a fine adjustment of the height of the drainage channel. If the coupling element is in a decoupling position, a rough height adjustment (rough adjustment) can take place and, if the coupling element is in a coupling position, a finer height adjustment (fine adjustment or readjustment) can be carried out. In particular, the Height adjustment device in a first step (manually) adjustable in height (can be lowered or raised) by (direct) force acting on the channel body, the first adjusting element being displaced axially. In a second step, a more precise (finer) height setting can be achieved by actuating the adjustment unit via a gear. The adjustment direction can be understood as a height direction of the drainage channel, that is to say in particular a direction (vertical) upwards or downwards.

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 transmission 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 located in the coupling position form, in particular, a screw drive. In particular, the transmission converts a rotational movement of one adjusting element into an (axial) linear movement of the other or the same adjusting element.

A height adjustment device 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 (coarse adjustment and fine adjustment).

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

In an advantageous development, the coupling element has first transmission means, in particular an internal thread, and the first adjustment element or the second adjustment element has second transmission means, in particular an external thread, wherein in the coupling position first transmission means and second Gear means engage in one another. In addition to threads, transmission means can also have gears.

In an advantageous development, the coupling element is designed in one piece with the first adjustment element or the second adjustment 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 designed in the form of a half nut or by any circumferential subsection 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 a movement (actuation), in particular a rotation, of the first or second adjusting element.

In an advantageous development, 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. In particular, the receiving structure forms a cylindrical cavity into which the first and second adjusting elements can be inserted (from above). A receiving structure can be molded onto a support body made of plastic, or fastened as a separate component to a base plate of the support body, in particular inserted into it.

In an advantageous development, 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 having a latching projection for engaging the first longitudinal groove or second longitudinal groove. 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 adjusting element is held in a defined decoupled (free) position during height adjustment and does not hinder the height adjustment process (rough adjustment). The second longitudinal groove has the advantage that the coupling element is held firmly in the coupling position in order to ensure that the transmission means work together. Longitudinal notes prevent unintentional twisting of the first adjustment element relative to the receiving structure. The locking projection can be designed as a rib, in particular as a bendable longitudinal rib.

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

In an advantageous development, 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 adjusting element can be rotated about the respective longitudinal axis, in particular from above, by means of the engagement profile, for example a transverse slot, hexagon socket, square or the like.

In an advantageous development, the support body has two opposing, in particular identically designed, receiving structures, in each of which an adjusting unit is received. 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, at least one spring, in particular a helical spring, acting in the adjustment direction is received in the support body, which is preferably connected to a base plate of the support body by means of locking lugs, in particular to support the channel body while the coupling element is in the decoupling position. A spring has the effect that the underside of the channel body can be supported by the spring force during the rough adjustment. When the coupling element is in the decoupling position or when the adjustment unit is set to a sufficiently low height, the channel body can be pressed against the spring force (manually) in the direction of the support body into a desired height position (rough adjustment). This enables a simplified assembly of the gutter system, since the fitter does not have to lift the entire gutter string (several interconnected gutter bodies) against gravity, especially when aligning the height of the entire gutter string, but only has to push the gutter string down slightly (manually) due to the spring forces must to the coarse adjustment to reach. 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 device (ruler, wooden slat, etc.) as a height stop for the rough adjustment of the channel run. The required height can be (finely) adjusted using the height adjustment device.

In an advantageous further development, the first adjustment element has at least one fastening element, in particular latching elements, at an upper end for the releasable, preferably rotation-free connection to the channel body, in particular the edge of a through opening of the receiving dome of the channel body. Fastening elements are preferably provided on both sides, which are designed in particular as clip connectors (beveled at the top).

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

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

In an advantageous development, at least one elevation element, optionally a plurality of elevation elements stacked on top of one another, is / are coupled to the underside of the support body. Such an embodiment enables a large height adjustment of a drainage channel. In particular, each elevation element 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 can be diverted into the subsurface via support elements are, while locking elements prevents lifting of the overlying elevation element or the support body. The fall elements have the function of spacers that provide a defined difference in height.

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 to the underside of the channel body, and a height adjustment device, 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 support surface of the first adjusting element.

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

In an advantageous development, 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 enables in particular access (from above) to the engagement profiles of the first and / or second adjusting elements, in particular in order to actuate them by means of a screwdriver.

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

In an advantageous further development, the channel body has several drainage slots, in particular running in a transverse direction of the channel body, which are separated from one another by 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 tapering or local cross-sectional thinning and serve to form predetermined breaking points (severable material webs). By breaking out material webs, several drainage slots can be connected to form a (larger) opening, for example to enable a (lateral) branch channel to be connected to the channel body.

In addition, break-out areas can be provided in the channel bottom, which enable the channel to be connected to local drainage pipes. Such breakout areas can also be provided by material thinning or severable material webs. For example, an eccentric plug-in socket can be used to connect a pipe to the channel body in order to connect a pipe to the channel body.

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

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 with the screws.

In an advantageous development, a height-adjustable end wall is attached to one end face of the channel body, the end wall being designed in particular in two parts, with a first end wall part in particular being connectable to the first end wall part in a height-adjustable manner via elongated holes. A first end wall part can be connected to the channel body in particular via clamping elements or a clamping connection. A height-adjustable front wall can have a supporting effect in order to ensure the load-bearing capacity of the channel body at the channel end, especially when the channel is cut to length at any point. A height-adjustable end wall can preferably be slipped onto one end of the channel, in particular via (lateral) clamping elements. In the case of a (continuous) channel run, a height-adjustable end wall is provided in particular only at one or both ends of the channel run. The end wall can function as a support foot at any position, especially after the channel body has been shortened (cut to length).

In an advantageous further development, the channel body forms opposing channel frames which each form spring elements extending towards the interior of the channel body. The grate can be centered by such spring elements, in particular an approximately equal gap size being achieved on both sides of the channel. In this respect, the spring elements can act as a grate centering.

In an advantageous development, a channel frame has a locking recess which is designed for engagement of a blocking section of a grate locking device inserted into a grate. in the In the area of the channel bottom, additional receiving devices for receiving a grate lock can be provided, 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 soffit drain element. This connection adapter is attached to the channel body in particular via a form-fitting connection.

4. d) Feinverstellung der Höhe des Rinnenkörpers während sich ein Koppelelement in der Kopplungsstellung befindet durch Betätigen der Verstelleinheit, insbesondere durch Drehen des ersten Verstellelements oder des zweiten Verstellelements.

1. a) placing a channel body on a height adjustment device, in particular a height adjustment device,
   wherein the height adjustment device has a support body and at least one adjustment unit with a first adjustment element extending along an adjustment direction, which is mounted axially displaceably in the support body, and a second adjustment element fixed relative to the support body in the adjustment direction;

3. c) moving the coupling element from the decoupling position into a coupling position in which the first adjusting element and the second adjusting element interact via the coupling element as a gear, in particular as a helical gear, in particular by rotating the first adjusting element or the second adjusting element;
4. d) Fine adjustment of the height of the channel body while a coupling element is in the coupling position by pressing 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 and the drainage channel. The method can implement some or all of the procedural features described in connection with the height adjustment device and the drainage channel.

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

This object is achieved by a grate locking device according to claim 1 (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,
  wobei der Druckabschnitt an einer Unterseite einen Abstützhebel zum Abstützen der Betätigungswippe gegen einen Rinnenkörper ausbildet und der Zugabschnitt an einer Unterseite einen Entriegelungsabschnitt und einen Verriegelungsabschnitt aufweist;

In particular, the object is achieved by a grate locking device for a grate comprising a drainage channel

• a housing for insertion into at least one mesh of the grate, the housing having a side recess;
• an actuating rocker mounted in the housing so as to be pivotable about a transverse axis, which has a pressure section on one side and a pulling section on the other side,
  wherein the pressure section on an underside forms a support lever for supporting the actuating rocker against a channel body and the pulling section has an unlocking section and a locking section on an underside;
• a locking rocker mounted pivotably about a vertical axis in the housing, which has a locking section and an unlocking section which, when the actuating rocker is pivoted, interact with the locking section or the unlocking section of the actuating rocker in such a way that a blocking section of the locking rocker for locking the grate to the channel body through through the side recess for engagement with a Locking recess of the channel body can be pivoted into or out of the locking recess to unlock the grate.

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

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

In an advantageous development of the invention, the unlocking section and the locking section each have beveled contact surfaces that are oriented opposite one another. In particular, the contact surfaces slide along the locking and unlocking sections of the actuating rocker during locking and unlocking.

In an advantageous development of the invention, the housing has a receiving slot open towards the underside for a support rod of the grate. The grate locking device is held (in the vertical direction) by the support rod (lattice spar) received in the receiving slot.

In an advantageous development of the invention, the support lever forms a grate lifting surface which is designed to reach under a support rod received in the receiving slot when the actuating rocker is pivoted to unlock the grate. In this way, the support rod is at least partially enclosed by the grate locking device. At the Lifting the grate by pulling on the pulling section of the rocker switch (in the fully unlocked state) also lifts the grate.

In an advantageous development of the invention, an upper side of the pressure section and the tension section does not protrude beyond the upper side of the grate in a locked state, and in particular ends 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 supporting against the channel body. This results in a steady or even levering movement of the grate.

The unlocking and locking sections are designed in particular as projections or as pins. The unlocking and locking sections of the actuating rocker are preferably formed in one plane, in particular oriented essentially perpendicular to one another. In particular, the rocker switch is 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, with at least one grate locking device according to the invention being used on one side of the grate, and on the other side of the grate in particular at least one locking hook of the grate engages in a locking recess of the channel body. By installing grate locking devices according to the invention on only one side, one-sided automatic lifting of the grate can be achieved.

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

The Figure 1A , 1B , 2A and 2B show a height adjustment device 1, 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 e.g. Fig. 4 ). Each adjustment unit 80 is received in a receiving structure 12 of the support body 10 and has a first adjustment element 21, a second adjustment element 22 and a coupling element 23. The first adjusting element 21 has two bearing 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 helical 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), allowing a certain amount of play. 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 via latching lugs 16 engaging in openings 56 in 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 successively in two steps by the height adjustment device 1, a coarse 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 work together as a gear 20 for fine adjustment, the function of which is described below.

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

The adjusting element 21 can be rotated back and forth between a coupling and a decoupling position, which in the Figure 2A or. 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, designed here 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 firm fixation, but only creates a resistance that can be overcome. By engaging the second longitudinal groove 212, the first Adjusting element 21 is held in a defined decoupling position when adjusting the height of the channel body 2 and does not interfere with the height adjustment process (rough adjustment). As a result of the engagement in the first longitudinal groove 211, the adjustment element 21 is securely held in position when the second adjustment element 22 (screw for fine adjustment) is turned during the fine adjustment of the height. The fine adjustment of the height level of the channel body 2 takes place via the rotation of the second adjusting element 22, which effects an axial fine displacement of the first adjusting element 21. The channel body 2 rests 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 work together as a gear (screw drive). In the coupling position, the form fit 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 uncoupling position of the coupling element 23 into a maximum height position. The channel body 2 is pressed down, for example, by the fitter's muscular 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 takes place with at least millimeter precision to the desired height level. The first adjustment element 21 has fastening elements 213 in its upper area for connection to the channel body 2. This connection does not hinder a rotation of the first adjusting element of FIG.

In order to be able to expand a drainage channel 100 in its total height 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 for coupling of crash elements 41. In addition, latching elements 42 are provided which engage in lateral recesses of the receiving openings 17. Elevation elements 40 have four conical support elements 41, which transfer the loads absorbed by the channel body 2 directly to the subsurface. In the embodiment according to Figure 3A and 3B two elevation elements 40 stacked on top of one another are connected to the support body 10.

Fig. 4 shows a drainage channel 100 with a channel body 2 made of plastic, in which several in connection with the Figures 1A to 2B Height adjustment devices 1 described are included. The channel body 2 forms a plurality of receiving domes 53 which are arranged spaced apart from one another in a grid and which are open to the underside of the channel body 2. The receiving domes 53 are provided for receiving an adjustment unit 80 or a receiving structure 12. Guide receptacles 55 for receiving the guide columns 13 of the height adjustment device 1 are provided below the channel frames 57. 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 in a prefabricated mounting dome 53 on site. Alternatively, the drainage channel 100 can be delivered to the construction site completely pre-assembled. This makes it possible to provide a corresponding number of height adjustment devices in FIG. 1 for different loads in order 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 enables the drainage channel 100 to be cut to length on the construction site in order to adapt it to the local conditions.

The second adjustment element 22 and the first adjustment element 21, in particular their engagement profiles 26 formed at the ends, 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 rotating 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 is blocked or released for coarse height adjustment or presetting. By turning the second adjusting element 22, a fine height adjustment or readjustment can be achieved.

In Figure 5A a section of the channel body 2 is shown with transversely running drainage slots 51, which are connected via break-out material webs 52 are separated from each other. The material webs 52 have thinned material 50 at the web ends which define predetermined breaking points. By breaking out individual material webs 52, an enlarged opening can be created in the channel body 2 for the connection of further components. Additional circular break-out aids for connecting the channel body 2 to local drainage pipes are provided in the channel bottom 58.

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

In the Figures 6A and 6B shows a drainage channel 100 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 manufactured 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 2 is cut to length at any point, the height-adjustable end wall 60 can be attached with a supporting effect. The end wall part 61 is fixed at the cut-to-length point of the channel by means of clamping elements 65. 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 continuously changed 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. If elevation elements 40 are used, the shown second end wall part 62 can be replaced by a longer L-shaped plate in order to ensure a supporting effect for the channel body 2.

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

In the Figures 8 to 13 is an inventive grate locking device 3 made of plastic for a grate 4 of a drainage channel 100, whose Function 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 fixed positively to a support rod 90 and / or filler rod of the grate 4 by means of latching hooks. In the closed state, the grate locking device does not protrude upwards or downwards from the grate 4.

The grate locking device 3 consists of a housing 30 with two identical housing halves, the actuating 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 gutter frame 57 or intervenes in them. The shape of the actuating 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 latching lugs protrude from the grate, which 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 mounted pivotably about a transverse axis Q in the housing 30 and has a pressure section 32 on one side and a pulling section 33 on the other side. The pressure section 32 has a support lever 34 on the underside in order to be able to support itself against the channel body 2 when the actuating rocker 31 is actuated to lever the grate 4 out of the channel body 2. The pulling section 33 forms an unlocking section 33a and a locking section 33b on the underside. The locking rocker 35 is mounted pivotably about the vertical axis H in the housing 30 and has a locking section 35b and an unlocking section 35a. When the actuating rocker 31 is pivoted for locking, the locking section 33b of the actuating rocker 31 interacts with the locking section 35b of the locking rocker 35. When the actuating rocker 31 is pivoted for unlocking, the unlocking section 33a of the actuating 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 grate 4 from lifting out of the channel body 2. The beveled and oppositely aligned contact surfaces 37a and 37b of the locking rocker 35 act in a sliding manner at contact points the unlocking section 33a and the locking section 33b of the actuating rocker 31 together in order to generate an opposite pivoting direction of the locking rocker 35 in each case.

The housing 30 has a downwardly open receiving slot 38 for receiving a support rod 90 of the grate 4. The support lever 34 forms a grate lifting surface 39a which, when the actuating rocker 31 is pivoted, pivots over the receiving slot 38 and in this way engages under or encloses the support rod 90 received in the receiving slot 38. In this way, in the unlocked state, the grate 4 can be lifted out of the channel body 2 via the grate locking device 3.

If the actuating rocker 31 is rotated by pressing on the pressure section 32 and then pulling on the pulling section 33, which is only possible in one direction, the locking rocker 35 rotates so that the blocking section 36 moves into the grate 4. As in the Figure 12A 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 the in Figure 12A pivotal movement shown leads. As a result, the blocking section 36 is moved out of the locking recess 70, whereby the grate 4 is no longer secured against being lifted out.

When the rocker switch 31 is rotated further by pulling on the pulling 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 on one side out of the channel, as in FIG Fig. 13 shown. The open or unlocked position of the grate locking device 3 is in the Figures 10A and 10B shown. One advantage of lifting out the grate 4 on one side is that the grate 4 can also be removed from installation locations in which, for example, the facade partially protrudes beyond the inside of a channel. The grate 4 can be pulled out of the channel body 2 by pulling on the actuating rocker 31, more precisely on the pulling section 33 be lifted. The grate lifting surface 39a of a rib of the actuating rocker 31 engages under the support rod 90, which prevents the grate locking device 3 from being released from the grate 4 by the force of the lifting process.

When the grate 4 with the grate locking device 3 is inserted into the channel body 2 and the rocker switch 31 is rotated in the opposite direction to the previously described rotational movement, the grate automatically lowers onto the grate support surface 75 of the channel body 2 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 being lifted 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 Figures 14A and 14B the underside of the channel body 2 is shown. Spring receptacles 78 for receiving upper ends of the springs 14 received 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. At the end of the channel body 2, sliding / locking devices 76 are provided for connecting adjacent channel bodies 2 to form a channel run and for length compensation of temperature-related changes in length.
