Description

The present invention relates to a trough system for discharging water in road construction, yard drainage and the like, having a gutter body having a bottom portion and side walls and forming an upwardly open U-profile, and at least one cover unit to the top cover of the gutter body wherein the cover unit has a cover element. Known tray systems are used to remove water or other liquids and can be found in road construction and road construction, but also for yard drainage and similar applications. The well systems are mostly constructed of a plurality of individual gutter bodies which are longitudinally adjacent to one another to provide a continuous gutter for discharging water. The gutter bodies have a substantially U-shaped form and have two opposite, substantially vertically extending side walls and a bottom portion.
In order to cover the gutter body to form the trough system, cover units are provided, which are placed on the upper side of the gutter body. It is known to form the cover units in two parts, and there may be frames be provided, on which the cover elements are placed. The cover units may also be arranged adjacent to each other to provide a continuous cover of the channel body along the trough system.
The cover units are often either placed only on the gutter body or screwed with this with the aid of screw, whereby on the one hand the assembly cost is increased, and on the other hand, the temporary cleaning of the trough system is difficult. To clean the tray system, the cover must be opened, and if the cover units are arranged resting only on the gutter body, without fixing them in the longitudinal direction of the gutter body, disadvantages may arise in the repeated closing of the gutter body by the cover units.
Out DE 202 00 509 U1 a device for locking a covering grate on drainage or drainage inside (in particular concrete or plastic concrete) is described. The channels have longitudinal head profiles made of formed sheet metal, into which a grate can be inserted. On the grid are on each longitudinal side downwardly facing, the edge contour of the grate in the position of use downwardly projecting pin formed. On the opposite side, the free legs of the channel have niche-shaped inwardly open recess for receiving the pins. The recesses are thereby released from the edge profiles that they are equipped in the recesses with notches.

From the DE197 31 585 is a gutter known with rust. It has on its side walls frames, which are fixed by means of locking pins in the side walls.

It is therefore the object of the present invention to provide a tray system which has a simplified structure and which enables an improved arrangement of the cover units on the channel body.
This object is achieved on the basis of a trough system according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

The invention includes the technical teaching that a frame is present, which has encircling, with which the frame is placed on the side walls of the gutter body and which enclose the side walls at least on the upper side and wherein the frame arranged in the Umgriff pins, which in pin receptacles can be used, which are introduced on the upper side in the side walls, wherein the frame with the pin and the Embraces is integrally formed.

The invention is based on the idea to position the cover units in a simple manner on the gutter body by the frame having geometrically advantageous means which can be brought into coincidence with corresponding means on the gutter body to both a lateral and a longitudinal acting Positioning of the cover to create on the gutter body. Advantageously, the grips and the pins are integrally formed with the frame, and without the use of additional means, for example, without the use of screw, the cover units can be arranged and positioned in an adjacent manner on the upper side of the gutter body. In this case, the positioning of the cover unit takes place transversely to the longitudinal extension of the channel body through the enclosures, and the positioning of the cover unit in the longitudinal direction of the channel body is made possible by the pins on the frame, which engage in the pin receptacles in the side walls of the channel body.

With the solution according to the invention for the positionally accurate arrangement of the covering units on the channel body, rapid assembly of the covering units on the channel body is possible; in particular, the position of the covering units on the channel body can be determined geometrically in a simple manner. This also ensures that the number of cover units, which is arranged above each of the channel body, remains constant.

Due to the positionally accurate arrangement of the cover units on the channel body, the covering units can be arranged in the transition between two channel bodies such that they can cover a first channel body with a first section and a second section with a second channel body. Consequently, if two channel bodies border each other in the longitudinal direction, a cover unit may extend beyond the abutment region of the channel body. If the pins arranged on the frame of the covering units now engage in the pin receptacles in the channel bodies, positioning of mutually adjacent channel bodies takes place at the same time.

For example, two cover units can be arranged on a gutter body, which cover the gutter body in the full length, and on the respective end sides of the gutter body two further covering units are placed, each cover, for example, half adjacent gutter body. Consequently, not only the cover units are positioned to each other on the gutter body, but the gutter bodies are also positioned by the cover units to each other.

Advantageously, for the connection between the frame and the channel body clip elements may be provided by which the holding arrangement of the frame on the channel body is further improved, and when the clip elements are used to connect the frame with the channel body, a lifting of the cover unit from the channel body is effective prevented. The clip elements can advantageously be arranged on frame and channel body in such a way that the clip elements surround both a part of the frame and a part of the channel body. If the frame is placed on the side walls of the channel body, and the clip elements are arranged on frame and channel body, the arrangement of the encircling around the top of the side walls and the engaging arrangement of the pins in the pin receptacles is secured by the use of the clip elements.

Advantageously, the frame has window-like recesses, through which and / or into which the clip elements can be inserted, in particular can be fed and inserted laterally. The frame of the cover unit may have a support portion, and side portions adjoin the support portion laterally. In this case, the window-like recesses may be introduced in the side sections, so that the clamping elements can be pushed by a lateral feeding through the window-like recesses in the side sections on the support portion of the frame and on the side wall of the channel body.

The side walls may have an upper-side collar portion, wherein the frame with the support portion on the collar portion can be placed, so that the clamping elements can enclose both sections by the C-shaped basic shape. Due to the C-shaped basic shape, the clamping elements form the effect of a clasp, through which the support portion of the frame is pressed onto the collar portion of the gutter body. In particular, so that the pins are secured in the pin receptacles, as a lifting of the frame from the channel body is prevented by the clip elements.

Due to the design of the clip elements made of a spring steel, these have a resilient compliance, and the C-shaped basic shape can be under elastic deformation open to be passed over the collar portion and the support portion. If the clamp elements are arranged on the frame and the channel body, they remain under elastic deformation on the frame and channel body, and a release of the cover unit from the channel body is effectively prevented even in the case of mechanical action, for example by driving over the cover units with a car.

The frame may be rectangular in shape and have four pins and four recesses, the pins and the recesses preferably being introduced in the corners or adjacent to the corners of the rectangular frame. In particular, the frame can be made square or have a rectangular shape with a longitudinal side, wherein the frame can be placed on the gutter body such that the longitudinal side of the frame corresponds to the extension direction of the gutter body. The pins on the underside of the frame can be arranged in the region of the corners, and furthermore the recesses for arranging the clip elements can also be introduced in the regions of the corners of the frame. If the clip elements are inserted into the recesses, they are in the mounted state in adjacent arrangement with the pins.

The cover unit can preferably be further developed in such a way that the cover element is rotatably arranged on the frame in an articulated arrangement. Thus, the advantage is achieved that the cover can be opened, while the frame remains in mounted arrangement on the gutter body. In order to form the articulated arrangement of the cover on the frame, the frame may have a receiving link, in which the cover element arranged Gelenkanformungen can be used. In this case, the receiving link and / or Gelenkanformung may be formed such that the cover is removable from the frame, in particular, the cover in a self-holding open arrangement on the frame can be brought. This advantages are achieved when cleaning the trough system, and the cover can be opened in the frame and can remain self-holding in the open arrangement on the frame, for example, while the gutter body is cleaned.

The receiving frame on the frame may have an opening side into which the Gelenkanformungen can be introduced on the cover, so that no further mounting means are necessary to form the hinged arrangement of the cover on the frame. Are the Gelenkanformungen in the Receiving frames on the frame, so the rotatable arrangement of the cover is already formed on the frame, and the Gelenkanformungen and / or the Aufnahmekulisse are geometrically designed so that the cover in the latching open arrangement on the frame can be brought. The cover element is rotatable by the articulated arrangement on the frame in an axis of rotation, and the axis of rotation preferably extends transversely to the longitudinal extent of the channel body.

With further advantage, a closure means can be arranged between the frame and the cover element, and the closure means is preferably located on the side opposite the articulated arrangement. The closure means may be formed by a spring element, which is arranged holding the cover member. In particular, the closure means may form a latching hook which can be locked in a latching recess on the frame. The latching hook can be made of a spring steel as well as the clip elements and this can be mounted self-holding on the cover.

If the cover is brought into the closed position by rotation in the articulated arrangement in the frame, then the latching hook can latch in the latching recess on the frame. The latching of the latching hook in the latching recess on the frame can be designed such that a lever tool may be necessary, which must be guided along the closure means in the direction of the latching recess, and the closure means can be pushed back by the lever tool from the latched arrangement in the latching recess of the frame be used to open the cover in the frame. To introduce the lever tool on the cover over in the direction of the closure means, a recess may be provided on the cover.
