Definitions

  • the invention relates to a cover for a manhole in a floor or for a shaft, which consists of an outer frame and a cover resting therein.
  • the invention is seen in that the frame and the lid are hinged together along one side, and that one and more of the gas springs are attached to the lid and the frame to the other end, the two end points of which are closer together when the lid is closed than with the lid open.
  • the invention addresses the difficulties previously encountered in two ways.
  • Two gas springs, the individual force of which is approximately 600 N, are usually sufficient.
  • the articulated fastening of the cover to the frame there are several options for the articulated fastening of the cover to the frame.
  • there are at least two hinges the common axis of rotation of which lies at the upper outer edge of the cover of the relevant side.
  • a strong hinge band can also be present, which then extends across the entire width of the lid.
  • the articulated connection is to be invisible from above, it is possible to use at least two stirrup joints, the common axis of rotation of which lies outside the seat between the cover and the frame; all contact surfaces between the cover and the frame are to be regarded as seats.
  • the latter option may require recesses within the floor or within the shaft wall underneath in order to make room for the stirrups in the rest position.
  • FIG. 1 shows a schematic sectional view of the cover according to the invention as an example of installation in a floor 1.
  • a Z-shaped frame 2 is let into a prepared hole within the floor 1 and secured in the floor 1 in the usual way by anchors or the like.
  • the frame 2 offers both a border and a support for a lid 3, which is shown in the set position in extended and in the rest position in dashed lines.
  • the lid 3 carries on its top the same ornaments or the same floor material as is laid on the floor 1 adjacent to the frame 2. For the rest, it is filled with concrete as a relining; however, these details are not essential to the invention, only the resulting weight is important.
  • the cover 3 is articulated to the frame 2 with the aid of at least two hinges, each hinge being formed by a perforated tab 6 and correspondingly aligned bores within the cover 3.
  • the common axis of the hinges runs approximately along the upper outer edge of this cover side, so that a pivoting movement approximately into the vertical is possible without hindrance.
  • At least two tabs 7 are attached to the lower leg of the same side of the Z-frame 2, each forming one end point of one of two gas springs 8.
  • the other end point consists of an eye 9 arranged on the underside of the cover 3 on each side, to which the piston rod of the gas spring 8 is articulated.
  • the lid 3 To close the lid, the latter is pivoted horizontally against the action of the gas springs 8, the gas springs 8 being almost completely compressed. Approximately halfway through the pivoting movement, the dead weight of the cover 3 gains the upper hand over the spring forces, so that from there on the cover must be supported if it is not to hit its seat in the frame 2.
  • the opening takes place in reverse order. First of all, the lid on the side facing away from the hinges must be raised so far - of course, the gas springs 8 have a supporting effect - until the balance in favor of the gas springs 8 has been exceeded. From this swivel position, the cover 3 is automatically erected into its installation position.
  • the cover according to the invention is shown in connection with a shaft.
  • a simpler angle frame 14 is provided in this exemplary embodiment, in which the cover 3 rests in the usual way.
  • the tab 7 is attached to an angle piece, which in turn is attached to the lower leg of the angle frame 14. Otherwise, the attachment of the gas spring 8 and the eye 9 to the cover 3 on each side does not differ from the exemplary embodiment according to FIG. 1.
  • the main difference lies in the articulated attachment between the cover 3 and the angle frame 14.
  • a bracket 16 With the help of one on the outside of the angle Frame 14 attached tab 18, a bracket 16 is mounted, the other end is fixed immovably, optionally adjustable on the underside of the lid 3 on each side of the lid.
  • the bracket 16 dips into a recess 15 in the underlying wall, which only needs to be recessed in the width of the bracket 16.
  • the embodiment according to FIG. 2 has the advantage that no hinge can be seen from the floor side, so there is the impression that it is a cover inserted in the usual way into a frame.
  • the edge of the cover 3 facing the two tabs 18 is slightly chamfered so that the lower edge of the cover does not collide with the upper edge of the angle frame 14 or with the top of the floor in the installation position.
  • the tabs 7 are each attached directly or indirectly to the frame 2 or 14. Particularly in the case of very small frames and also when retrofitting existing covers for embodiments according to the invention, it may be expedient to attach the tabs 7 directly in the masonry and not at one point on the frame. Here it depends on the local conditions, but this separate attachment of the tabs 7 does not change the effect of the invention.
  • the cover 3 lies directly on the corresponding frame parts. Seals can be provided here in a conventional manner, but this is irrelevant to the invention.
  • the lid 3 also has closures, openings or other fittings on its upper side, with the aid of which the lid can be positively closed or opened more easily.
