Definitions

  • a securing device for securing a cover grate on a drainage channel is known from EP patent 112 287.
  • the channel has recesses on opposite side walls into which a bolt (locking bracket) can be swiveled in by turning.
  • the bolt is loosely connected to the grate by a screw. If the screw is tightened, the bolt is first pivoted into the recesses as far as it will go and then clamped against the cover so that the cover is held securely on the channel.
  • This device has proven very successful. However, the work involved in locking and releasing the cover grids is considerable.
  • the present invention has for its object to design a device of the type mentioned in such a way that the work involved in locking and releasing the cover is reduced. Furthermore, tolerances of the gutter, cover and locking should not have any influence on the functionality.
  • FIG. 1 of a drainage channel 1 only the upper part of the two side walls 2 is shown. These have integrally formed longitudinally extending recesses 3, or the recesses 3 are formed with metal or plastic profiles, in which a cover, e.g. a grate 4 is inserted.
  • the grate 4 has two longitudinal ribs 5 on the side, which rest on the bottom of the recess 3.
  • the two longitudinal ribs 5 are connected to one another by transverse ribs 6. At least two of the transverse ribs 6 are thickened in the middle or are designed such that a passage with countersink 7 for receiving a bolt head 8 of a bolt 9 is created.
  • a bolt holding box 10 made of plastic is formed or inserted in the side walls 2 at the same height (as, for example, in EP-B 112 287) with internal recesses 11. This is turned by turning the bolt 9 clockwise into 2, a bolt 12 is retracted and then clamped against the grate 4 by turning the bolt 9 further.
  • the latch 12 is preferably made of rust-resistant spring steel. It has two webs 13 pointing downwards in the middle. The two webs 13 form the bolt in the region of their length a as a U-profile which is open at the bottom. The bar 12 thus becomes rigid in the region of this length a.
  • a clamping element 14 is clipped on from below in the middle of the latch 12.
  • the clamping element 14 has on the underside a cylindrical projection 15 with two centrally symmetrical clamping surfaces 17 rising helically to the axis 16 of the bolt 9.
  • the clamping surfaces 17 can be designed in one or more stages.
  • the clamping element 14 is equipped with two holding cams 18 on the upper side. It is pressed with these into transverse slots 19 'of the bolt 12.
  • the bolt 12 is thus connected to the tensioning element 14.
  • This two-part bolt has the advantage that the individual parts can be produced in completely different materials, such as the bolt 12 made of spring steel and the tensioning element 14 made of abrasion-resistant plastic.
  • a helically rising clamping surface 17 is followed in each case by a step 20 with a possibly lower, opposite slope.
  • the bottom step is delimited by a stop surface 21 and the top step by a stop surface 22.
  • the cross pin 24 is inserted during assembly together with the shaft 23 through a through hole 25 with two longitudinal grooves 26 in the bolt 12 and in the clamping element 14.
  • the longitudinal grooves 26 are provided at the locations of greatest axial thickness of the tensioning element 14. This prevents the latch 12 from falling off.
  • holding knobs 27 can be attached to the shaft 23 of the bolt 9, as shown in FIGS. 14 and 15, which likewise prevent the bolt 12 from falling off the bolt 9. This means that the complete quick lock can be completely pre-assembled with the grate like a conventional grate lock and can also be "blind" tightened.
  • the second embodiment according to FIGS. 7-13 differs from the first in that the bolt 28 is not or only partially resilient.
  • the spring 29 is latched as a separate element into the rectangular opening 30 of the latch 28 provided for this purpose.
  • the tensioning element 31 is designed in the upper area such that it can be snapped in laterally by means of the spring 29 with the holding webs 32.
  • the narrowing 33 on the side of the spring 29 prevents displacement of the latched clamping element 31.
  • the bolt 12, 28 with the bolt 9 with the grate 4 is loosely preassembled.
  • the cross pin 24 rests in the lowest position or hangs on the holding cams 27.
  • the bolt 12, 28 is first brought into engagement with the bolt holding box 10 until the surfaces 33 of the bolt 12, 28 on the stop surfaces 34 the bolt holding box 10 concerns.
  • the transverse pin 24 slides on one or the first clamping surface 17 until it engages on the notch 35 caused by the counter pitch 20.
  • the bolt 9 in the multi-stage clamping element 14 can be rotated one or two stages further. In the case of the single-stage tensioning element 14, the entire pitch b is bridged by this one stage and the tolerances are all taken up and compensated for by the spring element 19 on the bolt 12 or by the spring 29.
  • the bolt 9 When the fuse is released, the bolt 9 is rotated in the opposite direction until the transverse pin 24 abuts the stop surface 21, whereupon the bolt 12, 28 is also rotated by the now positive connection.
  • the bolt 12, 28 is thus unscrewed again from the bolt holding box and the grate 4 can be lifted off. Due to the retaining knobs 27 on the shaft 23 of the bolt 9, the fuse on the grate 4 remains preassembled.
  • the bolt 9 only needs 1/4 to 1/2 turns to tighten and loosen. As a result, the assembly and disassembly of the grate 4 is particularly time-saving compared to other conventional systems. Due to the forced entrainment of the bolt 12, 28, the loosening and tensioning is very reliable. In order to ensure that the bolt 12, 28 is securely retracted into the bolt holding box 10, the bolt 12, 28 can also have end curves 36 and inclined surfaces 37 on the upper side.
  • the longitudinal grooves 26 in the bolt 12 and in the clamping element 14, 31 can also be omitted if the cross pin 24 is inserted into corresponding through holes in the shaft 23 of the bolt 9. In this case, a washer 38 can be pushed over the shaft 23. If the cross pins 24 are firmly cast on, the washer 38 must also be cast on the bolt head 8.
  • the latch 12 is made of plastic.
  • the projection 15 of the clamping element 14 is integrally cast onto the bolt 12.
  • the latch 12 is flat and has a rectangular recess 45 on each side of the projection 15.
  • resilient rods 46 are preferably cast from spring steel, which are bent at right angles at the ends.
  • the two rods 46 can also be formed in one piece as a U-shaped rod with bent ends.
  • the bent portions 47 prevent the rods 46 from being displaced longitudinally in the plastic body.
  • the bars 46 can have a rectangular or round cross section.
  • the anchoring in the longitudinal direction can also be achieved by anchoring means other than the elbows 47, for example by transverse bores.
  • the resilient reinforcement can also be designed as a flat or curved plate.
