Definitions

  • the invention relates to a street cap according to the preamble of patent claim 1.
  • Such street caps are known (DE-A-2910598). They are used to accommodate the linkage of sliders of lines laid under the floor to enable appropriate access to the lines if necessary.
  • a slide sleeve is received in a longitudinally displaceable manner in a supporting frame and countered by a pressure screw with respect to the supporting frame. This makes it possible to move the slider sleeve relative to the support frame to the road cap setting movements of the road and the like. to be able to adapt.
  • Practice has shown, however, that such a road cap can still be improved in several respects despite the advantages achieved thereby.
  • a street cap which does not have a slide sleeve which is height-adjustable via a pressure screw, but in which the actual cap body is adapted to the respective street level by means of annular attachments.
  • the lid of the street cap is provided with a hollow cylindrical guide extension which is held in the cap body without tilting by means of longitudinal ribs, however the lid is not arranged in the cap body in a rotationally fixed manner.
  • the present invention has for its object to further develop a road cap of the type under consideration so that the traffic loads can be absorbed and derived into the foundation without danger to the slide linkage included in the cap and without damaging the road cap itself, the road cap being simple Way should be adjustable to the road level.
  • the slide sleeve according to the invention is arranged in a rotationally fixed manner within the support frame, for which purpose the slide sleeve has a flattening on its outer circumferential surface which extends at least over the displacement region and the inside of the support frame is designed with a complementary flattening.
  • the slide sleeve is mounted tilt-free in the support frame. Due to the rotationally fixed mounting of the slider sleeve with simultaneous displaceability in the longitudinal direction of the support frame, it is ensured that the slider sleeve together with the pressure screw maintains a predetermined position in the circumferential direction, regardless of the level setting, so that damage to the slider linkage is reliably excluded.
  • the support frame is expediently embedded within the frost protection layer, specifically in a rotationally fixed manner, for which purpose a flattening is preferably provided on the outer circumference of the support frame. This means that there are no voids around the supporting frame.
  • the support frame serves as a stabilizer for the pressure screw and slide linkage, whereby tilting of the pressure plate is excluded due to the expediently one-piece design of the pressure plate and support frame.
  • the arrangement of the pressure screw as close as possible to the longitudinal axis of the support frame is particularly advantageous for the introduction of the received traffic loads.
  • a migration of the pressure screw under load is expediently prevented in that the pressure screw with a corresponding recess sits loosely on a centering lug provided on the base of the support frame.
  • the inner surfaces of the guide webs are expediently flush with the guide surface of the guide flange, so that they also serve as guide surfaces for the slide sleeve and thus facilitate level control, which is caused by the rotation of the slide sleeve due to the fixing of the slide sleeve Pressure screw can be made simply by turning the pressure screw.
  • the cover is also expediently arranged in a rotationally fixed manner within the slide sleeve, so that it is secured against being unscrewed due to rolling traffic loads. There, too, the cover is expediently fixed via a flattening. It is also expedient for the cover to engage with a pin in a corresponding bore in an inner flange on the slide sleeve.
  • a road cap generally designated by the reference number 1, comprises a support frame 2, a slide sleeve 3, which is guided in a longitudinally displaceable manner therein and is supported on the support frame 2 by a pressure screw 4, and a dowel 5 seated on the slide sleeve 3.
  • the support frame 2 has a bottom or pressure plate 6 at the bottom and a support frame flange 7 projecting beyond the outer circumference.
  • the pressure plate 6 of the support frame 2 is provided with an opening 8 for the passage of a slide linkage 9.
  • the opening 8 has a comparatively large diameter compared to the slide linkage 9 and is located eccentrically to the longitudinal axis of the support frame, as shown in FIG. 1.
  • the support frame 2 is firmly embedded in the frost protection layer, for which purpose the outer circumferential surface 10 of the support frame 2 is designed to be non-circular, for example as a polygon.
  • the circumferential surface 10 is preferably provided with a flattening 11, which ensures that the support frame 2 is firmly seated within the frost protection layer even when exposed to external loads. Only this rotationally secure seat prevents the formation of cavities and prevents any damage to the slide linkage 9 which is introduced into the interior of the supporting frame via the opening 8 in the pressure plate 6.
  • the flattened portion 11 extends over the entire length of the supporting frame 2, is also formed in the support frame flange 7.
  • the slide sleeve 3 is guided by a guide flange 12 at the upper end of the support frame 2 with little play.
  • the guide flange 12 extends slightly into the interior of the support frame 2 and is preferably formed all around. Since the guide flange 12 with the outer circumferential surface 13 of the slide sleeve 3, which is otherwise smooth over the entire length, forms only a small ring slot 14 due to play, clogging of the area between the slide sleeve 3 and the support frame 2 is prevented by material from the road.
  • the slide sleeve 3 is supported in relation to the support frame 2 by the pressure screw 4, which is received eccentrically to the longitudinal axis of the support frame 2 in an inner flange 15 provided with a corresponding screw thread.
  • the pressure screw 4 is arranged overall eccentrically to the support frame 2, but as close as possible to the longitudinal axis of the support frame, so that there is a favorable introduction of forces from the slide sleeve 3 to the support frame 2.
  • the slide sleeve 3 is arranged in a rotationally fixed manner within the support frame 2, for which purpose, according to the embodiment according to FIG. 1, the outer peripheral surface 16 is provided with a flattened portion 17 which can be seen in more detail in FIG. 2. Accordingly, the support frame 2 is provided on the flange side at 12 with a corresponding flattening. Otherwise, the outer circumferential surface of the slide sleeve 3 continues on both sides of the edge of the flat 17 in a uniform cylindrical manner over the entire length of the sleeve.
  • the smooth outer circumferential surface of the slide sleeve 3 is essential because only in this way is it possible to lower the slide sleeve 3 accordingly despite the bituminous material being poured onto the side.
  • the cover 5 has two guides, for which purpose the cover 5 rests on the one hand with its ring shoulder 18 on a corresponding ring flange 19 of the slide sleeve 3 and engages with little play with a projection 20 into the opening delimited by the ring flange 19 of the slide sleeve 3.
  • a rotation lock is brought about in that the two inner circumferential surfaces 21 and 22 of the slide sleeve 3 opposite the cover 5 as well as the corresponding counter surfaces of the cover 5 are provided with a flattening 23 according to FIG. 2.
  • a rotary movement is therefore excluded, so that even one-sided loads on the cover 5 as a result of external loads cannot lead to the cover being unscrewed.
  • the ring flange can have a bore in which the cover can engage with a pin.
  • the pressure screw 4 rests on a centering nose 25, which is expediently conical.
  • the pressure screw 4 has a correspondingly conical recess at the bottom, as can clearly be seen in FIG. 3.
  • FIG. 3 The embodiment shown in FIG. 3 is basically similar to the embodiment shown only schematically in FIG. 1, but further details can be seen from this.
  • the support frame 2 has guide webs 26 on its inside, which extend to the base plate 6 and are expediently formed in one piece on the support frame 2.
  • the guide webs 26 run out in the guide flange 12, the guide surfaces of the guide webs 26 and the ring flange 12 being flush with one another.
  • the guide webs serve to prevent any tilting of the slide sleeve 3 relative to the support frame 2.
  • the guide webs 26 are arranged at a circumferential distance from one another, in the exemplary embodiment shown two guide webs 26 being arranged in the area of the flattening of the supporting frame and the two other guide webs 26 being arranged diagonally opposite to this. Furthermore, the rib-like guide webs 26 define hollow chambers between them and the upper guide flange, which collect dirt particles passing through the annular slot 12.
  • FIG. 4 shows quite clearly, the inner flange 15 receiving the pressure screw 4 delimits with the opposite inner wall of the slide sleeve 3 an opening with a comparatively large cross section for the passage of the slide rod 9.
  • the opening is therefore sufficiently large to to avoid any damage to the slider linkage by parts of the slider sleeve 3.
  • the passage opening 27 for the slide linkage 9 on the side of the inner flange 15 is delimited by a circular or elliptical arc 28 (FIGS. 2 and 4).
  • the slide sleeve 3 is provided at its lower end with an insertion bevel 29 in order to facilitate the insertion of the slide sleeve 3 into the support frame 2.
