Definitions

  • the invention relates to a drainage channel according to the preamble of patent claim 1, as well as a mounting device according to the preamble of patent claim 15.
  • a surface cover is used in the gutter body, are formed in the locking openings for locking elements of the cover grate.
  • These locking elements are latching tongues which engage in the latching openings and connect the cover grid with the surface cover.
  • the invention has for its object to provide a drainage channel of the type mentioned above and a mounting device for the cover of a drainage drainage, in which a solid and durable durable seat of the specified Abdeckrosts is guaranteed, and yet the cover grille when needed conveniently removed without damage and again can be determined.
  • the holding device is a cost-effective and reliable component that can be mounted on the cover grate or incorporate into this, is able to produce a high holding power for the cover grate, and above all ensures a comfortable handling when removing the cover grate. It only needs the flexible connecting element to be displaced relative to the cover grid, so that it releases the hook from its holding engagement. This is done conveniently with both hooks at the same time.
  • the connecting element is expediently tensile strength, but flexible enough to be able to be displaced with little effort.
  • a simple, introduced by a breakthrough of the cover grate hook can be used, with which the connecting element is attracted locally to the cover, until the hooks are released from their holding engagement and the cover grille yields.
  • a simple rod could be pressed onto the connecting element until the hooks are released and the cover grate can be removed.
  • Even a lateral displacement of the connecting element by means of a rod-shaped or pin-shaped tool, for example is sufficient to release the hooks from the holding engagement. Due to the local displacement of the connecting element or of a partial section of the connecting element, namely, the distance between the ends of the connecting element which are coupled to the hooks is shortened so that the hooks are automatically lifted out of the depressions.
  • the engagement force of the hook can be chosen to be relatively high, as well as over the connecting element with a translation effect and high hook engagement forces are easily overcome.
  • the connecting element is a flexible tension element, for example a plastic cord, a rope or a wire, which is flexible but nevertheless tensile.
  • the tension member may be fixed to the hook in any manner.
  • the connecting element is a bending spring with a certain flexural rigidity.
  • the hook and the connecting element are integrally formed. This ensures, for example, that the coupling does not come off automatically even after a long period of use of the drainage channel.
  • the hooks with the connecting element and a spaced apart from the connecting member Montiersteg which is mounted on the cover grid or incorporated into this form a one-piece mounting frame.
  • the support frame is conveniently mountable at suitable positions of the cover grate. There may be incorporated along the cover grate a plurality of such support frame (corresponding to the positions of the recesses in the channel body).
  • the support frame is a cost-producible one-piece plastic molded part, preferably an injection molded part.
  • plastic material all types of plastics commonly used in drainage technology are suitable.
  • the support frame could also be wholly or partially made of metal.
  • the spiral spring has an approximately rectangular cross-section, wherein the longer sides of the rectangle are substantially parallel to the cover grating.
  • the spiral spring can be easily displaced by pressure from above or by train up or bend to release the hook from the retaining engagement.
  • the spiral spring offers the advantage of exerting on the hooks additional acting in the direction of engagement symmetrical forces, which reinforces the holding engagement and thus the fixing force of the cover grating.
  • the bending spring bent under a prestress when the hook is in the retaining engagement preferably with a curvature pointing to the convex bend side for the cover grid. Thanks to the bias of the spiral spring pushes both hooks evenly in addition to the wells, so that the legs of the hooks are not solely responsible for the holding effect. Furthermore, the bending of the spiral spring also indicates to unskilled persons in which direction the spiral spring is to be displaced in order to release the holding engagement of the hooks. The curvature also facilitates the insertion of the hooks into the recesses.
  • To release the hook is attacked at the desired bending section, in the displacement of both hooks are uniformly pulled out of the wells.
  • Each hook has, in an expedient embodiment, a leg and an outwardly facing nose, which can be introduced into the recess.
  • the connecting element is connected to the side facing away from the nose on the leg, suitably in the region of a transition from the leg into the nose connected.
  • the connecting element could also be coupled directly to the nose ends in order to have an optimal lever arm with respect to the leg for releasing the retaining engagement.
  • the spiral spring and the legs are at least approximately the same width.
  • an engagement structure may be provided on the mounting bar, which enables a clean positioning of the support frame on the underside of the cover grate, or even cooperates with engaging elements provided there.
  • At least one hole in the mounting bar allows the attachment of the support frame to the underside of the cover grate, for example by means of a fastening screw which may be accessible at the top of the cover grate or hidden there.
  • inwardly offset offsets are provided between the mounting bar and the legs.
  • the offsets make it possible to avoid unwanted contact in the corner regions of the support frame with the cover grille, and to predict a desirable flexibility or a desired bending stiffness of the legs of the hooks.
  • the connecting element is conveniently pulled with simultaneous release of both hooks from their holding engagement by a introduced by a breakthrough of the cover grate tool either towards the cover or pushed down from the cover grate.
  • the tool may be a simple wire or plastic hook in the former case, and in the second case a pin or the like.
  • a drainage channel R points in Fig. 1 a channel body 1 with an approximately U-shaped cross-section.
  • the gutter body 1 can be made of any conventional material in this technology, for example, concrete, cast iron or a plastic-concrete composite material.
  • the open top of the channel body 1 is closed by a cover grate 2 with openings 3.
  • the cover grate 2 is releasably fixed on the gutter body 1, by means of a mounting device 4. Over the length of the cover grate 2, a plurality of such support devices are expediently provided.
  • a reinforcement 7 for example made of metal or plastic, which forms a fold 8 for receiving a Flanschse 9 of Abdeckrosts 2.
  • a fastener 11 is arranged, for example a screw which defines together with a nut 18 a transverse mounting web 12 of the mounting device 4 on the underside of the cover grate 2, for example in a corresponding groove.
  • the mounting bar 12 could be incorporated directly into the cover grate 2.
  • the Montierstegs 12 are inwardly offset offsets 13 are formed, which are continued by downward striving legs 15 resilient hooks 14.
  • the legs 15 extend in the in Fig. 1
  • a nose 16 is integrally formed on the outside, which engages in the recess 6 and sets the cover grate 2 on the gutter body 1.
  • the two hooks 14 are coupled together by a flexible connecting element 19, which are connected, for example in the region of transitions 21 in each case between the leg 15 and the nose 16 on the side facing away from the nose 16 of the leg 15.
  • the connecting element 19 can be fixed in any manner on the hook 14, and could also attack closer to the free end of the hook 14 as shown.
  • the connecting element 19 may be a flexible and tensile tension member, such as a plastic cord, a wire or the like (not shown), and in the illustrated embodiment, a bending spring having a rectangular cross section is approximately as wide as the legs 15.
  • the connecting element 19 designed as a bending spring has sections 20 of enlarged cross-section and higher bending stiffness adjacent to the hooks 14, and a predetermined bending section 22 of reduced cross-section and reduced bending stiffness between the sections 20.
  • the bending spring is biased in the engaged position shown the hook 14 with a bend so that it assists the legs 15 when depressing the lugs 16 in the wells 6 with compressive force components.
  • the convex curvature side of the spiral spring has z. B. to the underside of the Abdeckrosts. 2
  • the Montiersteg 12, the hook 14 and the connecting element 19 form, preferably, as a one-piece plastic molded part, preferably injection molded part, a holding device in the form of a support frame.
  • the Montiersteg 12 may have an engagement structure 17, for example, for cooperation with engagement elements 23 on the underside of the cover grate 2.
  • the mounting device designed as a support frame 4 is first mounted on the underside of the cover grate 2. Then the cover grille 2 is placed on the open side of the channel body 1 and pressurized from above until the lugs 16, thanks to their outer inclined surfaces 16a, are displaced inwardly and the inner walls 5 slide along into the recesses 6. In this case, the connecting element 19 is bent more than in Fig. 1 shown.
  • the connecting element 19 is pulled towards the cover grate 2 until the lugs 16 from the wells. 6 emerge and the cover grate 2 can be pulled upwards.
  • the connecting element 19 could also be pushed away downwards in order to release the lugs 16 from the retaining engagement.
  • Fig. 2 shows in a side view of the holder device 4 with the shape of a one-piece plastic support frame in the mounting bar 12 a through hole 25 for the fastener 11 of Fig. 1 ,
  • the through-bore 25 leads to a lower-side receptacle 24 of the Montierstegs 12, in which receptacle 24, for example, a nut rotatably and captively positioned.
  • the side view also clearly shows the sections 20 of the bending element formed as a bending element 19 with increased cross-section and thus higher bending stiffness and the intermediate bending bending section 22 with reduced cross-section and reduced bending stiffness.
  • the connecting element 19 could also be straight or bent downwards.
  • the curvature of the connecting element 19, if this is not a cord or a wire, is expedient in order to prevent the connecting element 19 from hindering the inward pivoting of the legs 15 during insertion of the lugs 16 into the channel body 1.
