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 by a height adjustment device according to claim 1, a drainage channel according to claim 15 and by a method for adjusting the height of a drainage channel according to claim 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 is movable 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, 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 screw gear, in particular for the axial fine adjustment of the first adjusting element.

An idea of the invention is to propose a height adjustment device for drainage channels, which enables a coarse adjustment and a fine adjustment of the height of the drainage channel. 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 uses one 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). The 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 uncoupling position or when the adjustment unit is set to a sufficiently low height, the channel body can (manually) be pressed against the spring force in 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, particularly when aligning the entire gutter strand, does not have to lift the entire gutter strand (several gutter bodies connected to each other) 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 stacked one above the other, is / are 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 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 sliding / latching devices on the end face for connection to an adjacent channel body, in particular latching lugs oriented downwards or in the longitudinal direction of the channel body for engaging in corresponding recesses in the channel body arranged adjacent. 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 opposite channel frames, each of which forms spring elements that extend toward the interior of the channel body. 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 floor, additional holding devices can be used to hold a grate lock 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 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.

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. There is also when lifting one through dirt or otherwise with the Channel body jammed grate the danger of also lifting the channel body, since the channel body is typically not fixed on the surface. This can be prevented by automatically lifting the grate during unlocking by means of a grate locking device according to the invention.

In an advantageous development of the invention, the unlocking section and the locking section each have oppositely aligned beveled contact surfaces. In particular, the contact surfaces slide along the locking or unlocking sections of the actuating rocker when locking and unlocking.

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.

The first adjustment element 21 , the second adjustment element 22 and the coupling element 23 act as a transmission 20th for fine adjustment, the function of which is described below.

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

The adjustment element 21 is rotatable between a coupling and a decoupling position, which in the 2A respectively. 2 B are posed. The adjustment element 21 has two longitudinally parallel grooves, namely the first longitudinal groove 211 and the second longitudinal groove 212 on. The reception structure 12th forms a corresponding locking projection 122 from, here designed as a longitudinal rib, at least partially in the first longitudinal groove 211 or the second longitudinal groove 212 can intervene. This intervention does not achieve a fixed fixation, but only creates a resistance that can be overcome. By engaging the second longitudinal groove 212 becomes the first adjustment element 21 when adjusting the height of the channel body 2nd held in a defined decoupling position and does not interfere with the height adjustment process (rough adjustment). By engaging the first longitudinal groove 211 becomes an adjusting element 21 when turning the second adjustment element 22 (Screw for fine adjustment) held securely in position during fine height adjustment. The fine adjustment of the height level of the channel body 2nd takes place via the rotation of the second adjusting element 22 , which is an axial fine displacement of the first adjusting element 21 causes. The gutter body 2nd lies with the underside on the support surface 210 on. The first adjustment element 21 and the second adjustment element 22 are positively coupled to each other 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 respectively. 22 get lost during transportation.

The feathers 14 are over latches 19th with the base plate 11 connected and lift the gutter body 2nd in the decoupling position of the coupling element 23 to a maximum height position. Pressing down the channel body 2nd takes place, for example, through the muscle strength of the mechanic. This rough positioning (rough adjustment) is achieved by locking the first locking element 21 by rotating the coupling element 23 secured in the coupling position. Then the fine adjustment is made to the desired height level at least to the millimeter. The first adjustment element 21 has fasteners in its upper area 213 for connection to the channel body 2nd on. This connection hinders a rotation of the first adjusting element 21 Not.

The connection adapter 71 has an adapter opening 74 on and is via a positive connection, namely on the gutter body 2nd molded support pins 72 and guide tabs 73 , on the channel body 2nd attached.

In the 8th to 13 is a grate locking device according to the invention 3rd made of plastic for a grate 4th a drainage channel 100 provided, the functioning of which is described below. The rust locking device 3rd is from above in the grate between two meshes of a grate 4th made of steel. The grate locking device is activated by locking hooks 3rd form-fitting on a support rod 90 and / or filler rod of the grate 4th fixed. The grate locking device does not protrude up or down from the grate when closed 4th forth.

The rust locking device 3rd consists of a housing 30th with two identical housing halves, the operating rocker 31 and the locking rocker 35 . The housing 30th has a side recess 301 on, by the blocking section in the locked state 36 protrudes sideways and into a locking recess 70 in the channel frame 57 dips or engages in them. The shape of the operating rocker 31 prevents the locking rocker 35 twisted and the blocking section 36 in the rust 4th emotional. Per meter of rust 4th are typically one-sided two grate locking device 3rd installed. On the opposite side of the grate, immovable locking hooks or locking lugs protrude from the grate, which in corresponding locking recesses 70 of the gutter body 2nd protrude into it. This is the rust 4th secured against unintentional lifting.

The operating rocker 31 is about a transverse axis Q in the housing 30th pivotally mounted and has a pressure section on one side 32 and on the other side a train section 33 on. The printing section 32 has a support lever on the underside 34 on to stand against the gutter body 2nd to be able to support when the operating rocker 31 to pry the Rust 4th from the gutter body 2nd is operated. The train section 33 forms an unlocking section on the underside 33a and a locking section 33b out. The locking rocker 35 is about the height axis H in the housing 30th pivoted and has a locking portion 35b and an unlocking section 35a on. When the operating rocker is swiveled 31 the locking section acts to lock 33b the operating rocker 31 with the locking section 35b the locking rocker 35 together. When the operating rocker is swiveled 31 the unlocking section acts to unlock 33a the operating rocker 31 with the unlocking section 35a the locking rocker 35 together. The locking section engages in the locked state 36 the locking rocker 35 through the side recess 301 and the side recess 91 of rust 4th through into a locking recess 70 of the gutter body 2nd and prevents the grate from lifting out 4th from the gutter body 2nd . The bevelled and oppositely aligned contact surfaces 37a and 37b the locking rocker 35 act smoothly at the contact points with the unlocking section 33a or the locking section 33b the operating rocker 31 together, each around an opposite pivoting direction of the locking rocker 35 to create.

The housing 30th has a receiving slot that is open at the bottom 38 to hold a support rod 90 of rust 4th on. The support lever 34 forms a grate lifting surface 39a off when the rocker is swiveled 31 through the slot 38 pivoted and the in the slot 38 recorded support rod 90 in this way engages under or encloses. In this way, the rust can be unlocked 4th via the grate locking device 3rd from the gutter body 2nd be excavated.

If the operating rocker 31 by pressing the print section 32 and then pulling on the train section 33 the locking rocker turns, which is only possible in one direction 35 so that the blocking section 36 in the rust 4th emotional. As in the 12A turned off, the blocking locking section 33b moved away and the unlocking section 33a the operating rocker 31 presses against the obliquely shaped contact surface 37a of the unlocking section 35a the locking rocker 35 what to the in 12A shown pivotal movement leads. This becomes the blocking section 36 from the locking recess 70 moved out, causing the rust 4th is no longer secured against lifting.

If the operating rocker 31 by pulling on the train section 33 the support lever is pressed 34 with the arched support surface 39b against the grate contact surface 75 of the gutter body 2nd and lifts the grate 4th out of the gutter on one side, as in 13 shown. The open or unlocked position of the grate locking device 3rd is in the 10A and 10B shown. An advantage of lifting the grate on one side 4th is that the rust 4th can also be found at installation locations where, for example, the facade partially protrudes from the inside of a gutter. The rust 4th can be done by pulling the rocker switch 31 , more precisely at the train section 33 , from the gutter body 2nd be lifted. The grate lifting surface engages 39a a rib of the operating rocker 31 under the support rod 90 , thereby releasing the grate locking device 3rd from the rust 4th is prevented by the force of the lifting process.

If the rust 4th with the grate locking device 3rd in the channel body 2nd is inserted and the operating 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 gutter body 2nd . The rocker switch presses 31 at the end of the rotation on an inclined contact surface 37b the locking rocker 35 , causing the locking rocker 35 moved back to the locking position. The blocking section engages at the end of the rotational movement 36 in the locking recess 70 the gutter frame 57 and secures the rust 4th against digging.

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

In the 14A and 14B is the underside of the channel body 2nd shown. They are spring recordings 78 for receiving upper ends of the in the support body 10th recorded feathers 14 as well as receiving openings 77 shown for threaded nuts. In the opening 77 screws can be inserted around the grate 4th with the gutter body 2nd to screw. On gutter body 2nd are sliding / locking devices at the ends 76 for connecting adjacent channel bodies 2nd for a channel run and for length compensation of temperature-related changes in length.
