Definitions

  • the invention relates to a grate for the formation of running mats or wipers, consisting of a plurality of profiled bars, strips or the like, which are oriented parallel to one another with their longitudinal axes and provided with undercut grooves in the longitudinal direction thereof, and the profiled bars, strips or the like Spacing connecting elements, as well as flexible insert strips, for example Felt, brush material, rubber or textile covering, which by thin-walled rails made of spring-hard material, each with two flanges and a bridge connecting them, e.g.
  • the holding elements with undercut shaped head parts can each be inserted into an undercut groove on the underside of the profile bars, strips or the like, and on the other hand the rails made of spring-hard material into an undercut Engage the groove on the top of the profile bars, strips or the like.
  • a grate of this type is already known from DE-B 2 719 857.
  • the grate according to DE-B 2 719 857 also has the advantage that it can be assembled relatively easily and almost in any size from prefabricated individual parts. It is therefore possible to have grids of the type known from DE-B 2 719 857 and DE-C 2 412 151, which are used to form running mats or wipers, also produced to a large extent in workshops for the disabled.
  • the grates of the known type mentioned above still have certain shortcomings. They require - due to the system - a relatively large minimum height, which is due to the fact that the undercut grooves for the engagement of the holding elements and for the accommodation of the flexible insert strips in the profile bars, strips or the like lie on top of each other, but also results from the fact that the holding elements connecting the profiled bars, strips or the like at a distance from one another must be passed under the profiled bars, strips or the like, since they form the actual support supports for the grate.
  • the use of the holding elements as support supports for the gratings results in an impairment of the dimensional stability when walking on a comparatively large distance is provided between adjacent holding elements.
  • the profile bars, strips or the like can then bend elastically in their length region lying between two adjacent holding elements to a degree which is equal to the thickness of the regions of the holding elements which support the profile bars, strips or the like.
  • DE-A 3 124 529 has also already proposed a grate for the formation of running mats or wipers in which the undercut grooves for engaging the holding elements on the long sides of the profiled bars, strips or the like are formed in order to achieve a relatively low minimum height are.
  • the invention has for its object to provide a grate for the formation of mats or wipers of the type explained in more detail above, which can be created with a minimal overall height, ensures a large-area and thus dimensionally stable support in use, and a simple assembly of all individual parts, as it were the push button system - allows.
  • the individual elements of the grate should receive training that ensures their simple and inexpensive manufacture.
  • the main advantage of this configuration is that all of the individual elements of the grate to be coupled together can be coupled to one another on simple assembly tables by placing them on top of one another in a specific order and locking them together by pressure from above.
  • undercut, undercut longitudinal grooves are relatively narrow slots of shallow depth, which have upward, arrowhead-like undercuts.
  • the top-side, undercut longitudinal groove is relatively wide and deep and its undercuts are formed by an at least trapezoidal cross-sectional widening lying below a trapezoidal cross-sectional constriction.
  • the profile bars, strips or the like and also the holding elements each consist of an extruded plastic profile which has at least approximately the same wall thicknesses in all wall areas - that is, also adjacent to the undercuts.
  • the essential components for a grate according to the invention can be easily and inexpensively manufactured.
  • the profile bars, strips or the like have a substantially U-shaped cross section, which is provided on the outside on the flanges and in the vicinity of the web, each with a downwardly and outwardly molded hook profile , whose inward-facing hook approach lies with its underside at the same height as the top of the profile web.
  • the holding elements also have an essentially U-shaped cross-section and each of their flanges is formed by two mutually mirror-image hook webs projecting from the profile web, the mutually facing back surfaces of which are spaced apart from one another and which together limit an upwardly arrow-shaped cross-section.
  • a grate according to the invention by coupling a larger number of profile bars, strips or the like by means of holding profiles which have a length corresponding to the profile bars, strips or the like, it proves to be particularly advantageous according to claim 9 to form the holding elements by sections cut off from the extruded plastic profile, the length of which corresponds to only a fraction of the length of the profile bars, strips or the like.
  • the features indicated in claims 7 and 8 make it possible in a particularly simple manner to effect the assembly of grates in a kind of push-button-like assembly technique.
  • the profile bars, strips or the like and the holding elements are each held in coupling engagement with one another by their arrow-shaped undercut elements in such a way that their webs form the bearing surfaces of the grate lying approximately on a common plane.
  • the holding elements consist of a non-slip, soft material, preferably rubber free of plasticizer, and slightly with the underside of their web, e.g. project by 0.5 to 1 mm over the underside of the profile bars, strips or the like. It has been shown that this not only achieves a secure position for the gratings on smooth floor surfaces, in particular polished stone floors, but also counteracts scratching or other damage to the same.
  • a particularly advantageous design for a grate forming the subject of the invention is obtained according to claim 12 in that the profile bars, strips or the like each contain on their underside an undercut longitudinal groove lying close to one long side and a cantilever projecting sideways over the other long side, have a holding element provided with an upwardly directed head part.
  • an assembly simplification for the grate is achieved, because when assembling each profile bar or profile strip only needs to be connected to one holding element. It is therefore important in this case if, according to claim 13, each holding element is molded directly onto the profile bars, strips or the like. It has proven particularly useful if, according to claim 14, the profiled bars, strips or the like are made of hard plastic together with the holding element made of soft rubber by an extrusion process.
  • the holding element according to claim 15 is made of non-slip, soft material, preferably soft material cher-free rubber, and that according to claim 16 the laterally projecting section of the holding element - namely its web - projects slightly with its underside, for example by 0.5 to 1 mm, over the underside of the profiled bars, strips or the like.
  • the main rust support is also brought about by the holding elements, while their inherent elasticity prevents the supporting floor surface from being scratched or otherwise damaged by the profiled bars, strips or the like.
  • the holding rails for the resilient insert strips consist of plastic injection molded parts, the web of which is designed as a hollow body with a double trapezoidal cross-section, while their flanges are integrally formed and protruding groups of pins at predetermined intervals from one another or carry pens.
  • the web of the holding rails can be designed as a closed hollow body, while their flanges carry the pins or pins near their free longitudinal edges.
  • the web of the holding rails may be provided with openings at predetermined intervals from one another in the side walls containing the constrictions, while their flanges carry the pegs or pins approximately halfway up and below them to the wall of the web descending breakthroughs included.
  • the holding rails are manufactured within the predetermined and thus fixed amount and are coupled in different numbers with the resilient insert strips to be locked, depending on the length of the profile bars, strips or the like of the grate used to hold the resilient insert strips. Due to the double trapezoidal cross-section of the hollow body forming the web of the holding rails, the holding rails with the flexible insert strips carrying them can also be latched easily and without play by means of a push-button-like connection technology in the profiled bars, strips or the like of the gratings. The double trapezoidal cross-section of the web of the holding rails interacts automatically with the correspondingly adapted, profiled cross-sectional design of the longitudinal groove assigned to the upper side in the profiled bars, strips or the like.
  • a further development feature according to claim 20 also consists in the fact that the web of the holding rails designed as a hollow body has at least one stiffening transverse wall. This ensures stable but still elastic support of the resilient insert strips on the web of the holding rails.
  • the free longitudinal edges of the flanges on the holding rails have tooth-like projections projecting upwards at predetermined intervals.
  • the group of pins or pins it is possible for the group of pins or pins to be located on the inner sides of the projections projecting upwards. In many cases, however, it can also be useful if the groups of pins or pins and the perforations are each in the area of the protrusions projecting upwards.
  • the resilient insert strips are fixed in position in the holding rails by the pins or pins, and they are not only secured against lifting out, but also against longitudinal displacement.
  • the profile height of the support rails corresponds approximately to the clear height of the groove of the profile bars, strips or the like used to accommodate them, while the projections carrying the pins or pins on their flanges over the upper flange edges of the profile rails , strips or the like protrude.
  • a particularly important design feature of the invention also lies in the fact that the insert strips consist of three layers, namely a rot-resistant base or support layer, e.g. Made of polyurethane (PU) - or polyethylene (PE) plastic, a middle connection and impregnation layer as well as an upper needle fleece layer.
  • PU polyurethane
  • PE polyethylene
  • the insert strips have a high level of stability.
  • the base or support layer also has a positive moisture behavior, so that excessive moisture, even the complete wetting of the insert strips, does not cause any signs of rotting.
  • the middle impregnation layer of the insert strips lies within the holding rails at the engagement height of the pins or pins.
  • the penetration of the pins or pins into the impregnation layer ensures that the insert strips are held in a particularly robust manner, without impairing their good repetitive capacity.
  • a grate 1 In Fig. 1 of the drawing, only a portion of a grate 1 is shown, as it can be used to form running mats or wipers.
  • the grate 1 is formed from a multiplicity of profiled bars or strips 2 which are connected to one another at a distance from one another and with their longitudinal axes lying parallel to one another by holding elements 3 directed transversely to them and at the same time are kept at a distance from one another.

  • the shape and the weight of the profile bars or strips 2 that they are in all wall areas - ie also adjacent to the undercuts 9 ', 9 "and 13', 13" of the grooves 6 and 11 ', 11 "" - Have at least approximately the same wall thickness.
  • the underside longitudinal grooves 11 'and 11 "of the profiled bars or strips 2 with their arrow-tip-like extension areas 12' and 12" have a relatively small depth with a relatively small width
  • the groove on the top side, which has undercuts 9 'and 9 " is relatively wide and Their total depth is essentially determined by the respective length of the sections of the two flanges 4 'and 4 "which run parallel to one another.
  • the free ends of the two hook webs 16 'and 16 ", each belonging to one of the flanges 15' and 15", define an upward, approximately arrowhead-shaped cross section, which corresponds to the cross section of the arrowhead-shaped extensions 12 'and 12 "on the profile bars or - afford 2 is adjusted.
  • the profile web 17 of the holding elements 3 has a thickness which corresponds to the thickness of the web 5 on the profile bars or strips 2.

  • the cross-sectional shape of the profile bars or strips 2 according to FIGS. 4 and 5 essentially corresponds to the cross-sectional shape of the profile bars 2 shown in FIGS. 1 and 2. The only difference is that the profile bars and strips 2 according to FIGS 4 and 5, only a slot-like longitudinal groove 11 'and arrowhead-like extension 12' is formed.

  • This structure of the insert strips ensures good repetition capacity because the elasticity of the material accelerates the regression of the pressure points and at the same time guarantees good dimensional stability with excellent cutting edge strength.
  • a positive moisture behavior is also achieved, i.e. the insert strips can absorb excessive moisture without damage and tolerate complete soaking. Gratings with these insert strips are therefore suitable for wet rooms.
  • the web 22 having the double trapezoidal cross section is not designed as a closed hollow body. Rather, it has perforations 28 in the mutually mirror-image walls 24 'and 24 ", each provided with a constriction, which are located one after the other at predetermined intervals and are each above the height of the walls 24' and 23" delimited by the walls 23 'and 23 " 24 ".
