Definitions

  • the invention relates to a frame and a cover or grate supported in the same with at least one locking device according to the preamble of claim 1.
  • Such frames with lids or grates are used to close manholes and floor openings.
  • GB-A-257 318 shows a generic frame and cover, in which the arms of the locking device, of which only one is used for locking, but the other serves to facilitate the removal of the cover, are rigid and straight. They are apparently held in the same by friction, which, however, only occurs in a very narrow area in the vicinity of the locking position, so that unintentional unlocking can occur relatively easily.
  • the object of the invention is to design generic devices such that the arms of a closed locking device are each pressed under elastic deformation against the guide links and are therefore in at least frictional contact with the latter, so that the locking cannot be released without considerable effort.
  • the winding or arch-shaped design of the arms means that their length and thus their elastic flexibility is increased while maintaining a relatively large cross-section and thus without impairing the robustness of the locking device. This enables a relatively large deformation path for the arm ends, so that they can be in frictional contact with the guide link over a longer distance. This reduces the risk of unintentional unlocking.
  • the invention is based on the consideration that the locking device should be designed such that an elastic deformation and thus a pretensioning force can be generated on it, so that the part to be held is not only held positively in its storage but also with a pretensioning force its storage can be pressed.
  • 1 shows a first embodiment of a locking device.
  • a frame 1, in which a cover 2 is inserted, is arranged as an end of the opening above an opening (not shown).
  • the cover 2 is supported on an inner flange 3 of the frame 1.
  • the frame 1 and the cover 2 are aligned on the upper side 4, which also usually forms the level of a floor (not shown) in which the frame 1 with the cover 2 is installed.
  • a bore 5 is arranged, which merges into an enlarged bore section 6 on the top of the cover, an annular shoulder 7 being formed between the bore 5 and the enlarged bore section 6.
  • a locking device 10 is used to hold the cover 2 in the frame 1.
  • the locking device 10 has a closing member 11, which is composed of two arms 12. It is also possible to use more than two arms 12, for example three or four, which collide with one end at a connection point and firmly with one another are connected.
  • a support rod 14 is fixedly connected to the arms 12, which runs essentially perpendicular to the arms 12.
  • a storage and actuation device 15 is arranged, which is designed as a head 16.
  • the head 16 has, for example, a hexagon shape on which a hexagon key can be placed, with which the locking device 10 can be rotated.
  • the head 16 is formed on its underside as a bearing surface 17, which is located on the shoulder 7 between the bore 5 and the enlarged bore portion 6.
  • the arms 12 have the shape of a turn, their ends are guided on the guide link 20 of the inner flange 3.
  • the guide link 20 is designed as an inner circumferential ring surface with a decreasing diameter. This means that when the locking device 10 is rotated into its closed position, the arms 12 of the closing member 11 are compressed and thereby elastically deformed. A preload is created in the locking device 10, with which the cover 2 is held in the frame 1. In the end position, i.e. in the closed position of the locking device, the arms 12 snap into a latching recess 22, see the secondary figure b) of FIG. 1.
  • FIG. 3 A second embodiment 35 of a locking device is shown in FIG. 3. Your arms 34 are in contrast to the arms 12 1 arcuate and are guided on a guide link 40.
  • the guide link 40 is designed such that, on the one hand, the arms 34 are pressed together as in the embodiment according to FIG. 1 and, on the other hand, there is an elastic bending deformation.
  • Such a locking recess 38 is also provided in the embodiment according to FIG. 3, see the secondary figure c) of FIG. 3.
  • the locking recesses 22, 38 of the locking devices according to FIGS. 1 and 3 have the purpose, the arms 12, and 34 not only to hold in a frictional engagement, but also in a positive engagement, so that the removal of the locking device from the closed position requires a certain amount of effort.
  • the cover 2 shows an arrangement of two locking devices 35 corresponding to FIG. 3.
  • the cover 2 is of such a size that the use of a single locking device, as in the case of smaller openings according to FIGS. 1 and 3, would be unsuitable, since it would have to be made more solid and would therefore require a greater amount of material.
  • locking devices 12 can also be used.
  • the corresponding guide link 20 must then also be used instead of the guide link 40.
  • the storage rod 14 has been shown with the storage and actuation device 15. This is not necessary, but different heads 16 could be used, for example, which could have an internal hexagon, a cross-slot, a simple screwdriver slot or a square instead of the external hexagon, see secondary figure d) of FIG. 4.
  • the winding or curved arms 12 and 34 could also be placed in a horizontal plane without the function of the locking device 35 changing as a result.
