Definitions

  • the invention relates to a grate, in particular a bar grate for the formation of running mats or wipers using at least one grate field formed in one piece from plastic or metal, in which at least the longitudinal bars held at a predetermined distance from one another by transverse webs have a U-shaped or H-shaped cross section, in the longitudinally open grooves on the top of the insert strips made of deformable material, for example made of felt, rubber, bristle material or textile covering, can be attached.
  • Gratings of the generic type are already known, for example from DE-OS 26 43 315.
  • insert strips made of deformable material e.g. made of felt, rubber, bristle material or textile covering, then their attachment in the upwardly open grooves of the longitudinal rods is regularly effected by gluing.
  • Either the insert strips are provided with a self-adhesive coating on their underside from the outset, or the adhesive is applied to them or into the grooves of the longitudinal bars in a special operation.
  • the grate, in particular bar grate, according to DE-OS 26 43 315 is already designed so that it can be composed of several grate fields of a certain size, each formed integrally from plastic or metal. So that the individual grate fields can be coupled to be displaceable relative to one another, at least the outer flanges of the two outer longitudinal bars of the grate fields are provided with openings at predetermined grid intervals, in each of which an approximately push-button-like locking bolt can be inserted. Adjacent grate fields are connected to each other via the locking bolts with the interposition of spacers.
  • the purpose of the invention is to eliminate all the shortcomings of the known grate designs shown above.
  • the invention is therefore based on the object of creating a grate, in particular a grate, of the type explained in more detail at the outset, which enables simple use of a secure and, if necessary, easily detachable fixing of the insert strips in the longitudinal bars, but which is also usable without using insert strips - So a multi-purpose use allowed - and which can be connected in the desired size by simply combining a larger number of the same grate fields.
  • the flange inner longitudinal rod profile at equal intervals and are provided near the free flange ends with querroughsverengenden latching webs for positional fixing of the insert strip, respectively. It is also important that the longitudinal bar profiles on their side faces of the profile webs opposite the grooves are provided with corrugations or serrations running in the longitudinal direction and that the grate field can be turned through 180 ° in its support plane. It is also important to solve the problem at hand that at least two relatively long longitudinal bar profiles of the grate field are seated on their profile webs have extension tongues that can be inserted to secure the position between the flanges of two longitudinal bars of an adjacent grate field.
  • At least two relatively far apart transverse webs of the grate field are equipped with extension tongues projecting over both ends of the outer longitudinal bars, one extension tongue each lying on the level of the transverse webs, while the other is formed offset by the material thickness of the transverse webs in the vertical direction relative to these.
  • the width of the insert strips which are matched to the opening width of the channels in the longitudinal bar profiles, are made of elastically deformable material, they can simply be pressed into the channels of the longitudinal bar profiles from above, only being elastically deformed in those areas and under tension be set in which the locking bars act on them. Because of the inherent elasticity inherent in the insert strips, a clamping on the longitudinal bar profiles occurs automatically in the area of the latching webs. As a result, the insert strips are held securely when walking on them; however, if necessary, they can still be detached from the longitudinal bar profiles with little effort.
  • the locking webs have a sawtooth profile widening downwards and inwards in a wedge shape from the free flange ends of the longitudinal bar profiles. This not only makes it easier to press the insert strips into the longitudinal bar profiles, but also ensures that they are securely seated during use.
  • Gratings according to the invention can be easily produced as one-piece molded parts, for example by injection molding or die-casting, if the locking webs are formed at a distance from slot-like openings provided in the profile web of the longitudinal bar profiles.
  • tongue-like shoulders can namely be formed in the injection mold, which enables an optimal shaping of the locking webs on the inside of the flange of the longitudinal bar profiles.
  • the rod grate At the place of use it can be decided at any time in which position the rod grate should be used, because on the inside of the flanges of the longitudinal rod profiles that delimit the troughs, the cross-sectional locking webs with which the cross-section narrowing are provided at regular intervals and close to the free flange ends Have insert strips easily and safely brought into and out of hold. So if the rod grate is to be used at the place of use with insert strips protruding over its surface, these simply need to be pressed into the grooves of the profile rods from above, only elastically deforming and coming under tension in the area in which the Act on locking bars. Because of the inherent inherent elasticity, the clamping on the longitudinal bar profiles then occurs automatically in the area of the latching webs. As a result, the insert strips are held securely when walking on them; however, they can be removed from the profile bars with little effort if required.
  • Grate fields with these characteristics can be arranged in parallel with the direction of their crossbars as well as parallel to the direction of their longitudinal bar profiles so that they can be shifted together with simple grips to form grates of different sizes.
  • the extension tongues are only located at one end of the longitudinal bar profiles. It is then possible either to provide all extension tongues on the same transverse edge of a grate field, or alternately on the two crosses to arrange the edges of a rust field. In the former case, the extension tongues should either only sit on even-numbered or only on odd-numbered longitudinal bar profiles of the grate field. In the second case, on the other hand, it would make sense to assign the extension tongues on one transverse edge of the grate field only to the odd-numbered longitudinal bar profiles and on its other transverse edge only to the even-numbered longitudinal bar profiles.
  • extension tongues are formed offset relative to the webs of the longitudinal bar profiles by their material thickness in the height direction.
  • extension tongues provided in the area of the transverse webs, it can also prove to be advantageous in some cases if a group of these has a U-shaped cross section into which the other group of extension tongues can be suitably inserted.
  • a relatively small section of a bar grate 1 is shown.
  • This has longitudinal rod profiles 2 and crosspieces 3 connecting them in one piece and is produced as a one-piece molded part made of plastic or metal, for example by injection molding or die casting.
  • the longitudinal bar profiles 2 have a substantially H-shaped cross section. However, they can also have a U cross section that is open at the top.
  • the crossbars 3 have a flat rectangular cross section.
  • Insert strips 5 made of elastic material, for example made of felt, rubber, bristle material or also textile covering, which are supported on the profile web 6 of the longitudinal rod profiles 2 can be pressed between the upwardly directed flanges 4 of the longitudinal rod profiles 2.
  • the longitudinal bar profiles 2 are each provided on the inside of their two flanges 4 at regular intervals and near the free flange ends with cross-sectional narrowing edge webs 7.
  • These edge webs 7 preferably have a sawtooth profile widening from the free flange ends downwards and inwards in a wedge shape, so that they facilitate the insertion of the insert strips 5 from above, but fix them securely in their pressed-in position by barbing them into the material with elastic material displacement Penetrate the side surfaces of the insert strips 5.
  • the shape of the locking webs on the inner flange sides of the longitudinal bar profiles 2 is facilitated if the locking webs 6 are spaced above slot-like openings 8 provided in the profile web 6 of the longitudinal bar profiles 2. In the area of these openings 8 there may be shoulders formed in the mold, which enable the sawtooth profile to be shaped for the latching webs 7.
  • openings 8 in the profile webs 6 of the longitudinal bar profiles 2 can prove particularly useful to have the openings 8 in the profile webs 6 of the longitudinal bar profiles 2 to be provided in each case where these are integrally connected to one another by the transverse webs 3.
  • the drawing figures 3 to 5 show a relatively small section of a modified bar grate 11. This also consists of a plurality of longitudinal bar profiles 12 running parallel to one another and crosspieces 13 connecting them integrally with one another.
  • the rod grate 11 is also produced as a one-piece molded part made of plastic - but possibly also made of metal - for example by injection molding or die casting.
  • the longitudinal bar profiles 12 have an essentially U-shaped cross section
  • the transverse webs 13 have a flat, rectangular cross section.
  • the transverse webs 13 are expediently arranged between adjacent longitudinal bar profiles 12 in such a way that they limit an H-shaped cross section with their flanges 14, which are oriented essentially normal to the bar grating plane.
  • the flanges 14 of the individual longitudinal bar profiles 12 integrally interconnecting profile webs 15 have a much greater material thickness than the flanges 14 and also as the transverse webs 13 and are on their side surface facing away from the flanges 14 with corrugations in the longitudinal direction of the longitudinal bar profiles 12 or Toothings 16 provided.
  • each longitudinal bar profile 2 each delimit a groove 17, in which, as can be seen in FIG. 4, insert strips 18 made of elastic material, for example as made of felt, rubber, bristle material or textile covering can be used, which are supported on the profile web 15 of the longitudinal bar profiles 12.
  • the cross-sectional narrowing webs 19 are formed on the inside of their two flanges 14.
  • These latching webs 19 in turn have the sawtooth profile widening from the free flange ends downwards and inwards in a wedge shape, so that they facilitate the pressing in of the insert strips 18 from above, but fix them securely in their pressed-in position by barbing them with elastic material displacement penetrate into the side surfaces of the insert strips 18.
  • the shape of the latching webs 19 on the inside of the flange of the longitudinal bar profiles 12 is facilitated if they are spaced above slot-like openings 20 provided in the profile web 15 of the longitudinal bar profiles 12. In the area of these breakthroughs 20 there may also be shoulders formed in the molding tool, which enable the sawtooth profile to be shaped for the latching webs 19.
  • the bar grate 11 can also be used without the insert strips 18.
  • These corrugations or serrations 16 then form the accessible area of the individual profile bars of the bar grate 11, which has practically the same width as the accessible area on the insert strips 18th
  • the described design of the bar grate 11 makes it possible to use it in two different positions of use, the walkable surfaces having a relatively soft and elastic effect in the use position according to FIG. 4, while the walkable surfaces are effective in the use position according to FIG. 5 Surfaces have a relatively high hardness.
  • a bar grating 21 is also shown in detail in FIG. 6 of the drawing. This can be composed of several, preferably structurally identical rust fields 21 ', 21 ", 21"'.
  • Each of the grate fields 21 ', 21 "and 21"' is formed with a predetermined length 22 and a likewise predetermined width 23 in one piece from plastic or metal and has a larger number of longitudinal bar profiles 24, which are connected to one another by transverse webs 25 and spaced apart are held.
  • the distance between the individual longitudinal bar profiles 24 corresponds to a predetermined grid dimension and also the distance Adjacent crosspieces 25 from one another are set to a certain grid dimension.
  • extension tongues 27 8 and 10 can be seen particularly clearly relative to the profile webs 26 of the longitudinal bar profiles 24 offset by their material thickness in the vertical direction.
  • the extension tongues 27 are arranged only at one end of the longitudinal bar profiles 24.
  • extension tongues 27 can be assigned to the same transverse edge of a grate field, as can be seen from a comparison of the upper section of the grate field 21 'with the grate field 21 ".
  • the arrangement can also be made in such a way that the extension tongues 27 alternately on the two transverse edges of a grate field, as indicated by the grate field 21 'In the latter case, it can prove to be advantageous if the extension tongues 27 on the two transverse edges of the grate fields 21' are offset from one another to have.
  • the extension tongues 27 are expediently provided only on the even-numbered longitudinal bar profiles 24, while on the opposite transverse edge they are assigned to the odd-numbered longitudinal bar profiles 24.
  • each grate field 21 ', 21 ", 21"' have extension tongues 28 'and 28 "protruding from both ends of the outer longitudinal bar profiles 24.
  • the extension tongues 28' are located in each case on the level of the crosspieces 25, while the other extension tongues 28 "are formed offset in relation to the material thickness of the crosspieces 5 in the height direction, as can be clearly seen from FIG. 8.
  • a grate field for example grate field 21 ', is placed on the surface to be covered with it. Further grate fields 21 "and / or 21" 'of the same design are then connected to this in the longitudinal direction and / or in the transverse direction. In order to achieve this, the further grate fields 21 "and 21" 'only need to be pushed sideways on their support surface to the transverse edges and / or longitudinal edges of the grate fields that have already been laid.
  • the extension tongues 27 of one grate field each enter the open ends of the longitudinal profile bars 24 of the adjacent grate field and act in the direction transverse to the longitudinal direction of the longitudinal bar profiles 24 to secure the position with the two profile flanges 29 of the respective longitudinal bar profiles 24.
  • Locking lugs 30 move into associated locking openings 31, which can be located in the profile web 26 of the longitudinal bar profiles 24 of the subsequent grate field 21 'or 21 ".
  • extension tongues 28 In order to obtain a shift-proof coupling between the grate fields 21 'and 21 "' via the extension tongues 28 'and 28", it has proven to be expedient, for example, to design the extension tongues 28 "as a U-profile which is open at the bottom, as that of FIG 11.
  • the extension tongues 28 ′ of the adjacent grate field which are flat in cross-section, engage in this U-profile and act together with the U-flanges 32 as a means of securing against displacement in the longitudinal direction of the longitudinal bar profiles 24.
  • extension tongues 28 'on their upper side with a latching lug 33 which engages with a matching latching opening 34 in the profile web of the extension tongue 28 " occurs.
  • the extension tongues 27 are arranged at the ends of the longitudinal bar profiles 24 such that they overlap the profile web 26 of the longitudinal bar profiles 24 when the grate fields 21 'and 21 "are pushed together, they have an arrangement according to FIG. 10, in which they engage under the profile web 26 of the longitudinal bar profiles 24. While the arrangement of the extension tongues 27 according to FIG. 8 can also be used if the longitudinal bar profiles 24 are designed as a U-profile open at the top, the arrangement according to FIG. 10 can only be used in conjunction with longitudinal bar profiles 24 with an H-shaped cross-section.
