The fastening devices comprise, on the one hand, fastening pieces on the covering and, on the other hand, fastening counterpieces on the gutter body. It is proposed to equip the gutter body with receiving devices into which various fastening counterpieces can be installed before or after installation into the ground. In this manner, the production costs and the operating costs of the surface drainage device can be reduced, in particular in the case of necessary structural alterations. <IMAGE>

Description

The invention relates to a surface drainage device according to the preamble of claim 1.

In particular, the invention is a drainage channel, which one is built into the floor Channel body a cover or a grate put on and with the gutter is connected.

From EP 81 762 C1 there is a drainage channel at the beginning known type, in which frames on the upper edges are made of cast metal, which have a mounting frame for to form a cover.

To attach the cover to the drainage channel Fastening devices provided, which on the one hand with the cover attachable fasteners and the other include fastening counterparts that can be connected to the channel body.

These fasteners can now be used in different ways Be trained. If the surface drainage facilities must meet particularly high requirements, so are generally used as bolts used in threaded holes (as fastening counterparts) are screwed in, which are attached to the frames are. The manufacture of such an arrangement is relative expensive because the threads are cut on the finished channel Need to become.

Furthermore, there are various fastening devices Principles known that work without screws. Examples of this are EP 204 278 A2 and EP 476 672 A1 and DE 31 33 658 A1 can be removed. These known arrangements are relatively expensive to manufacture.

From EP 81 741 B1 it is known that as a fastening piece can use a traverse, the one in the middle Has attached threaded hole in which a screw bolt is screwed through a hole in the cover is led. In the channel body are as fastening counterparts recesses substantially opposite one another provided that are designed such that the Traverse swung into the recesses when screwing down and is held there. This embodiment is particular used when medium to low strength requirements be put.

For example, DE-U-88 02 530 also discloses a drainage channel a floor and two parallel side walls having channel body, in which on the bearing surfaces Side walls provided a releasably fixed cover is, with a molded part made of plastic in each side wall is embedded, an insertion groove open to the gutter and receiving chambers for a crossbar Receiving chambers of both side walls are aligned opposite, the cross bar with its ends in the engages both receiving chambers. The cross bar is with a threaded hole for a fastening screw equipped with its shaft through a hole the cover extends and with her head on the cover supports.

All systems have in common that to a certain Training the body to be built into the ground certain training of the fasteners or Cover heard. On the one hand, this makes it impossible the surface drainage system to changed Adjust requirements, so that one particularly at completely new systems got to. The operating costs of the known surface drainage systems are therefore high. On the other hand the known systems require relatively high manufacturing costs, because different product lines are less Utilization of the machines and increased storage costs entail.

The invention has for its object a surface drainage device of the type mentioned at the beginning simple way to train that the total cost can be lowered.

This object is achieved by the specified in claim 1 Features resolved.

fertigen" Befestigungsgegenstücke aufweist, sondern lediglich Aufnahmeeinrichtungen vorgesehen sind, in welchen verschiedenartige Befestigungsgegenstücke einbaubar sind. Auf diese Weise kann eine Sorte" von Rinnenkörpern hergestellt werden, was die Herstellungs- und Lagerhaltungskosten erheblich senkt. Die Herstellung der Befestigungsgegenstücke, die in jedem Fall leichter handhabbar sind als die kompletten Rinnenkörper, ist einfach. Die Lagerhaltungskosten sind selbst bei sehr vielen verschiedenartigen Befestigungsgegenstücken gering.An essential idea of the invention is that the body does not

finished "counterparts, but only receptacles are provided, in which different counterparts can be installed. In this way, a Variety "of gutter bodies, which significantly reduces the manufacturing and storage costs. The manufacture of the fastening counterparts, which are easier to handle in any case than the complete gutter bodies, is simple. The storage costs are low even with a very large number of different fastening counterparts.

In addition to the receiving devices for different types, it is preferred Fastening counterparts with the channel body the recesses mentioned at the beginning for inserting a traverse fitted.

In a preferred embodiment of the invention the receiving devices are designed such that the fastening counterparts are removable after installation. This makes retrofitting very easy.

A plurality of receiving devices is preferably seen before and forms them in such a way that either fastening counterparts or damping elements for damping a vertical movement between cover and body can be used are. Such damping elements are known per se. This can further reduce costs, because for damping elements, that are only needed in special cases, none special training of the channel or its frames necessary is.

The mounting counterparts can be made with threaded holes equip so that screws can be used as fasteners are. This will create a screw connection much simplified. In particular, you do not have to thread cut the frame of an otherwise finished gutter.

For the production of a screwless fastening device are suitable counterparts, one on the body attached clamp spring and as attachments one at the Cover attached peg with a thickened when in use include leading front end formed in such a way are that the spigot in one to the plane in which the cover extends in a substantially vertical direction in a receiving opening of the clamping spring or its elastic Deformation can be used and is held during insertion. Such a snap fit ensures adequate attachment, where the assembly, i.e. the placement of the cover on the gutter is very simple.

The thickened section is preferably at the front end conical and at its end facing the cover frustoconical. This makes them ready for assembly forces required to lower the cover.

The receiving opening of the clamping spring is preferably elongated educated. This allows the pin on any Places used along the longitudinal axis of the receiving opening be so that the manufacturing tolerances of gutter and cover can be relatively high.

The clamping spring can be attached with play such that the pin, when inserted into the receiving opening, the clamping spring can move. This also serves large tolerances allow in the manufacture of gutter and cover.

The embodiment already indicated above is preferably in which the receiving opening is elongated is used and at the same time the clamping spring Play in only one direction, namely perpendicular to the longitudinal axis the receiving opening attached so that it from the pin at Insert in the receiving opening in the to the longitudinal axis of the Recording opening can be moved in the vertical direction. The two degrees of freedom are therefore different Way ensured what a very stable structure with it brings.

In a preferred embodiment, the clamping spring is in the essentially band-shaped and has a lower, essentially U- or V-shaped spring section and two adjacent U-shaped holding sections, each with one leg end in one leg of the spring section pass over and their open sides protrude outwards. The Clamp spring is then in a (preferably) rectangular Opening of a flat part arranged so that it with the legs of the holding sections two opposite one another Reaches over the edges of the opening of the flat part. On on the one hand, this is the assembly of the arrangement very much easy, on the other hand, the displacement of the clamping spring guaranteed.

As indicated at the beginning, the detachable one is generally sufficient Clamping seat, in which the force when assembling is greater than the force when lifting the cover. If you have bigger ones Wants to ensure holding forces, an embodiment is suitable in which the pin is rotatable about its longitudinal axis (in the cover) and its thickened end has two mutually opposite spreading surfaces, so that the pin for a parallel position of the spreading surfaces Spreads the clamping spring along the longitudinal axis of the receiving opening and removable from the receiving opening and into the receiving opening can be used. With a suitable dimensioning both the cone angle of the frusto-conical pin section as well as the opening in which the clamping spring sits thus ensuring that the connection is unsolvable. The cover can only be lifted off the gutter when you turn the pin.

A flat piece serves as the attachment point for the clamping spring, that can be inserted into a side open pocket in the frame is. It is also advantageous if the cover is a Holding nose, which then the flat piece against slipping out backs out of your pocket when the cover is on the gutter or body sits.

Not only one in can be used as the attachment point for the clamping spring the receiving devices can be used part. Much more can also use the traverse mentioned at the beginning (possibly also additionally) can be used.

Also suitable as a fastening device for screwless Fastening one that is characterized by that the fasteners at least one bolt, the stored in the cover and towards a longitudinal edge the cover in a locking position and out of this in an open position is displaceable, and that the fastening counterparts include a body counterpart that when moving the bolt in the locking position engages with the latch that the cover on the body is held. Such a bar is relatively simple manufacture and captively connect to the cover. The cover is preferably a cast grate.

The bolt preferably has latching devices which e.g. can be designed as a detent spring and with the cover are in elastic engagement. The locking device arrives engages with a counter-catch in the cover in such a way that the bolt in the locked position (preferably also in the open position) with the bolt piece in this position is fixed. This is an unintentional one Unable to open or remove the cover.

The latch is preferably in one of the recesses in the Cover attached, which as inflow openings for to be discharged Serve water. As a result, no additional occurs Weakening of the cover.

Here, the bolt preferably has an opening, which in the locking position together with the recess, in which the bolt is attached, forms an overall opening, which is essentially that of the other recesses corresponds in the cover. On the one hand, it will aesthetic requirements met, on the other hand a reduction in the inflow cross section Avoid absorption of water.

The recess in which the latch is attached is preferably as a slot open to the longitudinal edge of the cover educated. This allows the bolt to enter the opening from the outside be inserted.

The latch preferably includes a cover portion which is in the locking position the slot in its open Area closed up to the longitudinal edge. This is ensures that the surface of the cover is even runs without depressions and therefore no dirt accumulates can.

The surface of the bar is preferably over that the cover sunk so far that when driving over the Cover the latch remains unloaded. This is usually sufficient Fractions of millimeters. This ensures that the guides in which the bolt can be moved, permanently stay common.

The bolt is preferably in a direction of displacement vertical plane essentially double T-shaped or as Dovetail guide trained. The recess in the Cover is designed accordingly, so it has rails which are gripped by the bolt.

The latch is preferably on the longitudinal edge of the cover end facing away from a clearing device, the when opening and moving from the locked position Cleans dirt from the transfer track. This is a easy opening possible even after long use. Especially the clearing facilities are simple to design if they have sloping surfaces for lifting dirt when moving include. So the dirt is not compacted, but actually cleared.

Preferably, the locking counterpart comprises a nose, which in a holding recess of the cover in the area of the latch protrudes, the bolt a holding portion reaching under the nose having. Such a nose is very easy with the Pour the frame together on this. The holding recess in the cover is shaped to correspond to the nose, that moving the cover in the direction of its longitudinal edges, thus in the longitudinal direction of a drainage channel prevented becomes. The fastening device for fastening the Cover on the drainage channel thus forms at the same time a safeguard against the cover moving the gutter.

Preferably, a or are on a longitudinal edge of the cover several, in particular two bars and on the other, opposite Longitudinal edge, hook openings provided with hook elements on the body when putting the cover on the Body can be brought into positive engagement. For sure Keeping the cover on the channel body only has to a reduced number of bars can be provided.

The bolts and the bolt counterparts and, if applicable, the hooking elements and hooking openings are preferably symmetrical in this way arranged on the body and on the cover that the Longitudinal edges of the cover are interchangeable. This will make it It is easier to put the cover on the body.

Preferred embodiments of the invention result from the subclaims.

In the following description, the same or the same parts with the same reference numbers.

In Fig. 1, a drainage channel is shown in cross section, which has a channel body 1 with upwardly projecting side walls 2, 2 'and a bottom 5 and reinforcing ribs 4. On the upper edges 3, 3 'of the channel 1 are frames 10, 10 'in the material (polymer concrete) of the rest of the gutter body poured. The frames 10, 10 'have supports 6, 6' for Place a cover 30 on (in Fig. 1 with openwork Lines indicated).

There are recesses in the inner surfaces of the side walls 2, 2 ' 7, 7 'provided for the insertion of a crossbar.

Below is the design of the frames 10, 10 ' both are identical, explained in more detail.

The frames 10, 10 'are mirror-symmetrical to their normal perpendicular corresponding to the section line IV-IV from FIG. 2 built up. First pockets 11, 11 'are located near the edges and a second pocket 12 is provided in the middle. The Pockets 11, 11 'and 12 are designed so that fastening counterparts 20 can be used. These are below described in more detail.

Furthermore, hooking elements 13 are provided on the frames 10, 10 ′, which in corresponding recesses of the cover 30 can be used so that on the cover 30 to the outside projecting holding pieces 29 lie under the hooking elements 13 and so the cover 30 against the corresponding edge Secure lifting upwards. This will be further below explained in more detail.

The pockets 11, 11 'are designed so that cover elements 50 can be used instead of fastening counterparts 20. The damping elements 50 are made in a manner known per se formed of an elastic plastic and dimensioned so that they have a sufficient amount above the requirements 6, 6 'protrude so that when the cover is in place 30 somewhat compressed.

Furthermore, lugs 26 are provided on the frames 10, 10 ', which can cooperate with bars 60, which in one Cover 30 can be arranged. The way it works described in more detail below.

In Figures 2-4 and 7 are mounting counterparts 20 'and 20 '' shown, which have threaded holes 21, so that a cover 30 by means of screws (as fastening pieces) can secure on the gutter.

In Fig. 3, a mounting counterpart 20 is shown, which has a rectangular opening 25. This is for recording a clamping spring described in more detail below.

The pockets 11, 11 'and 12 are on the inside (in Fig. 3 to above) is slightly tapered. To this It is possible to design appropriately sized fasteners 20 drive in with light hammer blows that they sit securely in pockets 11, 11 'or 12. Means a screwdriver, the fasteners 20 nevertheless get them out of pockets 11, 11 'or 12.

A fastening device based on the Figures 9-18 explained in more detail, either that in the figures 2 and 3 shown mounting piece 20 (with a rectangular opening 25) or can be used directly in the frames. At direct insertion into the frame 10, 10 'becomes the opening above the central pocket 12 corresponding to the opening 25 educated.

The clamping spring shown in Fig. 9 has a lower one Spring section 22, which is substantially V-shaped is. Of course, it can also be U-shaped or Execute semicircular.

At the upper end of the clamping spring are holding sections 23, 23 ' provided which has a substantially U-shaped cross section have and each with one leg in one leg of the lower spring section 22. The holding sections 23, 23 'point outwards with their openings and form between them an elongated receiving opening 24. This clamping spring can be made of a band-shaped metal strip or be made of plastic.

This clamping spring is now either in a mounting counterpart 20 (Fig. 2) or directly into the frame 10, 10 '(as in 13-18 shown) used. Here is the arrangement dimensioned such that the clamping spring in Fig. 13 after can be moved left and right so that the edges the opening 25 more or less deep in the holding sections 23, 23 'intervene.

On the cover 30 is a pin 40 as a fastening piece attached, which, as shown in Fig. 11, has a tip 41, which sits at the end of a conical surface 42. The cone surface 42 goes into an oppositely inclined holding surface 43 above, the angle of the holding surface 43 is steeper than that Angle of the conical surface 42. The holding surface 43 in turn goes at its tapered end into a shaft 44, at the End of a head 45 sits.

In the cover 30 there is a receiving opening 29 (FIGS. 13, 14) is provided, through which a fastening piece 40 according to FIGS. 10-12 can be inserted into the opening 24, until it with its widened head 45 on a support surface 19 of the receiving opening 29 rests. This position is in Fig. 15 shown. Here, the holding sections 23, 23 ' such on the steeply shaped support surface 43 that a Pulling the fastening piece 40 out of the clamping spring 20 is practically not possible.

The fastening piece 40 can have a symmetrical shape, then the holding surface 43 is formed such that lifting the cover 30 with appropriate effort is possible.

In the embodiment shown in the accompanying drawings of the invention, the attachment piece 40, such as shown in Figures 10-12, no axisymmetric shape on. Rather, it has two spreading surfaces 47, 47 ', which have essentially the same diameter as the conical surface 42 at its thick end. These spreading surfaces 47, 47 'lie directly opposite each other. At a 90 ° angle to this are the Holding surfaces 43 and the shaft 44 are molded so that the in The configuration shown in Figures 10-12 arises.

Furthermore, the fastening piece has retaining lugs 46, 46 ', which at the rotational position of the fastener shown in Fig. 17 40 this in the receiving opening 29 by engagement under the bearing surfaces 19, 19 'against falling out to back up. In the rotational position shown in FIGS. 15 and 16 are the retaining tabs 46 and 46 'no longer under the bearing surfaces 19, 19 '(Fig. 14), but in the Receiving opening 29. In this way, the fasteners 40 put in a cover 30 and there hold captive.

Of course, it is also possible to replace the spreading surfaces 47, 47 'according to FIGS. 10 and 12 to provide sections, in which the holding surface 43 and corresponding Parts of the conical surface 42 by continuing the shaft 44 (as plane-parallel surfaces). The one in the figures 10-12 shown variant is preferred, however, in that an unwanted rotation of the fastening piece 40 in the opening direction by the necessary spreading of the Clamp spring is prevented.

When the cover 30 is placed on the channel 1 or its Frames 10, 10 'are the fastening piece 40 with its Tip 41 inserted into the receiving opening 24 and moves here - if the insertion does not happen in the middle - the Clamp spring to the right or left (in Fig. 13) so that the receiving opening 24 symmetrical to the longitudinal axis of the fastening piece 40 runs. Through the elongated training it is essentially indifferent to the receiving opening 24, at which end of the receiving opening 24 the fastening piece 40 is used. When pushing in the lower spring section 22 spread so that the holding sections 23, 23 'move outwards and the receiving opening 24 is widened until the conical surface 42 completely in the Receiving opening 24 is inserted. With further impressions (In the rotational position of the fastening piece shown in FIG. 15 40) the lower spring section 22 comes together again, so that the receiving opening 24 slides along the holding surface 23, until the cover 30 is firmly seated on the supports 6, 6 '. The dimensioning is chosen so that in the fixed State of the cover 30 that shown in FIG. 15 Position of the holding sections 23, 23 'relative to the holding surface 43 is guaranteed.

If you now the fastening piece 40 from his, in the Figures 15 and 16 shown, position rotates out 90 °, so the position shown in FIGS. 17 and 18 is reached. In this position, the spreading surfaces 47, 47 'press the Clamp spring apart so that the cover 30 is lifted off can be. In principle, it is indifferent to insert, in which rotational position the fastening piece 40 is. 17 is preferred, however, so that the final securing of the cover 30 on the gutter 1 or the frames 10, 10 'by turning the fastening pieces 40 reached by 90 °.

Another preferred embodiment of FIG Fastening devices with reference to Figures 19-27 closer explained.

As can be seen from these figures, the cover 30 Openings 31, 31 ', which are separated by ribs 37 are separated. The longitudinal edges 32, 32 'of the cover 30 have the hooking openings mentioned at the beginning on a longitudinal edge 32 ' 39 only in the surface of the cover 30 are sunk in, so that the holding pieces under the hook openings 29 lie.

The frames 10, 10 'are with the hooking elements mentioned at the beginning 13 equipped, which in the hook openings 39 advertise and thus lie on the holding pieces 29 come. At the other longitudinal edge 32 is the cover 30 with openings 39 'which pass through the entire cover 30, so that no holding pieces 29 on the other longitudinal edge 32 lie.

In the embodiment shown in Fig. 19, two are from each other spaced recesses 31 in the cover 30 carried out via a slot 33 to the longitudinal edge 32. This slot 33 has on its edge 32 facing End a holding recess 38 which is shaped so that the nose 26 formed on the groove is essentially form-fitting fits in. This is a shift in Cover 30 effectively prevented in the longitudinal direction of the channel.

The nose 26 has, as shown in Fig. 20, over and under free space.

The slot 33 or the associated opening 31 is with guide rails 36, 36 'provided inwardly in the slot 33 or the opening 31 protrude. The rails 36, 36 'are with Notches 68 fitted.

In each of the openings 31 provided with slots 33 a latch 60 is used, which has a double-T-shaped cross section has, as shown in Figures 21 and 25 is. In particular, the latch 60 comprises an upper cover plate 64 and a base plate 65, which with the cover plate 64 over an intermediate piece 66 of smaller width (in the longitudinal direction of the channel) connected is.

At its end facing the longitudinal edge 32 is the intermediate piece 66 so far on the base plate 65 and the cover plate 64 reset that a holding section 71 is formed, who can reach under the nose 26. The cover plate 64 is pulled as far out towards the longitudinal edge 32, that when the latch 60 is in its closed position (according to FIG. 19) with the longitudinal edge 32 essentially flush.

At its end facing away from the longitudinal edge 32 is the cover plate 64 provided with inclined surfaces 67 so that when moving the Riegel 60 (in Fig. 19 to the right) dirt that on the Rails 36, 36 'lies, can be lifted off.

To hold the latch 60 in its locked position a detent spring serves as well as in its open position 61, which the intermediate piece 66 with a holding portion 62nd (Fig. 27). At its end, the detent spring 61 is with outwardly bent latching sections 63, which then, when the latch 60 is in its locked position, snap into notches 68.

The bolt 60 is also provided with an opening 69, so that its ends (between the inclined surfaces 67) fork-shaped are designed. The opening 69 is designed in such a way that from opening 69 and the remainder of the opening 31 with slot 33 composed opening area of a corresponds to those in which the other recesses 31 in of the cover 30. This is clearly evident in Fig. 19 see.

The height of the surface 70 of the cover plate 64 (see Fig. 26) is slightly less than that of the cover 30, so that no force on the bolt when driving over the cover 30 60 or its surface 70 acts. They are also on the cover 30 over its surface 34 excellent Knobs 35 provided, on the one hand, the slip resistance increased, on the other hand, a load on the bolt 60 reduced when driving over.

The latch 60 is preferably made of high strength metal (e.g. made of a die-cast aluminum alloy), where its surface is passivated to avoid corrosion.

As can be seen from the pictures, the frames 10, 10 ' formed symmetrically with respect to the lugs 26. As a result are on the longitudinal edge 32 'opposite the longitudinal edge 32, on which there are the latches 60, recesses 47 (FIG. 20) are provided, in which those on the longitudinal edge 32 'are not required per se Find noses 26 place. This ensures that the cover 30 in any orientation on the Trough 1 can put on.

When putting on a cover 30 according to Figures 19-27 goes one now so that one tilts the cover 30 first and hooks with the holding pieces 29 under the hooking elements 13. Thereafter, the cover 30 with the latch 60 pushed back (pushed to the right in Fig. 19) completely placed. Then the latches 60 are closed (to the left in FIG. 19) pushed) until the locking sections 63 of the locking spring 61 in the Engage notches 68. The holding sections sit in this position 67 the latch 60 under the lugs 26, so that a Lifting the cover 30 from the channel 1 or the frames 10, 10 'is effectively prevented. To open it is the reverse Order.

On the cover 30 are preferably in the pockets 11, 12 downwardly projecting holding pieces 14 are provided, which close the pockets 11, 12 towards the inside of the gutter. This allows a fastening piece seated in a pocket 11 or 12 don't slip out.
