Definitions

  • the invention relates to a locking device for covers of shafts and other floor openings, which are covered with a cover or a grate, which cover or grate is used in a frame and its lifting or opening is only possible after removal of the locking device.
  • the invention relates to covers of different shapes and dimensions, such as those used for shafts laid in the ground and other openings in floors.
  • the latter are primarily understood to mean floors with which rooms in buildings and outdoors are covered and which need openings and serve as entry and exit, or to take goods out of the covered rooms or to bring them into them.
  • it is desirable that the covers or grids covering these openings are secured, i.e. cannot be lifted or removed or only with considerable effort.
  • an arm or arms is or are provided on the locking device, which or which to insert in the lid or the grate and with the production of an elastic deformation in the arm or in the arms with the The frame is intended to be in operative connection.
  • the invention also includes a cover of a shaft or of an opening provided in a floor, consisting of a frame and a cover or grate inserted therein, the cover or grate being equipped with a locking device according to the invention, and is characterized in that for receiving the Arms or the arms a channel is provided in the cover or in the grate and / or in the frame, the shape of which has or have a shape deviating from the outer shape of the arm or the arms, such that the arm or the arms during assembly an elastic deformation is forced on the locking device.
  • the locking device 1 shown in FIGS. 1 and 2 has a holding head 2, on which two arms 3, 4 protrude.
  • the arms 3, 4 have a circularly curved shape. In their position relative to one another, the two arms 3, 4 do not run parallel, but are directed apart. At their free end, the arms 3, 4 have a projecting surface 5 on the surfaces of the arms 3, 4 facing away from one another, the function of which will be explained below.
  • the holding head 2 is essentially cuboid, but can also be of a different shape and has an opening 6 of any shape in the center, which is used for inserting a tool when the locking device 1 is to be opened.
  • FIG. 3 and 4 the installation of the locking device according to FIG. 1 in a cover 7 of a shaft or another opening is shown.
  • the cover has a frame 8 with an inner flange 9, on which a cover 10 is supported.
  • a grate with the same circumferential shape can also be used.
  • a passage 12 is provided in the cover 10, which has an enlarged recess 13 on the upper side 11 of the cover, which serves to accommodate the holding head 2.
  • a widening channel 14 in the side walls 15 of which a curved, channel-shaped recess 16 is recessed.
  • the depressions 16 extend parallel to one another.
  • the arms 3, 4 are inserted, which must be compressed because of their diverging direction. This compression is greatest in the area of the projecting surface 5, since there the distance between the two arms 3, 4 is greatest and decreases the further the arms 3, 4 the recesses 16 are inserted.
  • the projecting surface 5 is located below the cover 10 and serves as a retainer so that when the cover is removed, the locking device 1 does not leave the passage 12 can fall.
  • a collar 17 is formed on the underside of the cover 10 and is interrupted in the region of the two arms 3, 4, so that the Passage of arms 3, 4 is not hindered. The collar 17 prevents the arms 3, 4 from being damaged when the cover 10 is removed.
  • the locking device 1 is held in the recesses 16 by a compression of the arms 3, 4 with a frictional connection.
  • reaching under the arms 3, 4 under the inner flange 9 results in a positive connection between the cover 10 and the frame 8.
  • the locking device 1 and the passage 12 do not have to be machined. This applies to all locking devices described here and the corresponding parts in the frame 9 or in the cover 10. Furthermore, the parallelism of the depressions 16 is not important. It is important that the arms 3, 4 experience a compression and are thus held in the cover 10 by a frictional connection.
  • the cross-sectional profile of the arms 3, 4 is expediently rectangular here. When disassembling the locking device 1, it is necessary to compress the arms 3, 4 to such an extent that the projecting surface 5 does not abut the bottom of the recess 16.
  • FIGS. 5 and 6 show an arrangement similar to that in FIGS. 3 and 4.
  • the arms 3, 4 of the locking device 1 run approximately parallel to one another in the unmounted state, but are spread apart during assembly, see FIG 6.
  • closed bores 18 are provided instead of the depressions 16.
  • the projecting surfaces 5 are now arranged on the mutually facing sides of the arms 3, 4.
  • the opening 6 in the holding head 2 has a stepped portion 19, under which the tool for opening the locking device 1 can be attached.
  • the same reference numerals are used in FIGS. 5 and 6 insofar as they designate identical parts from FIGS. 3 and 4.
  • a second locking device 20 is shown. It differs from the locking device 1 in that it has only a single curved arm 21, of which some cross-sectional profiles are shown in FIG. 9. Another difference is that two openings 6 are arranged on both sides of the arm 21, which also serve to disassemble the locking device 20.
  • Fig. 12 the same locking device 20 as shown in Figs. 10 and 11 is shown, but the channel 22 is designed with a larger radius of curvature than the radius of curvature of the arm 21. There is also an elastic deformation of the arm 21 and thus the formation of a frictional connection between the arm 21 and the bore 22. The free end of the arm 21 protrudes like the previous locking devices under the frame 8 and forms a positive connection.
  • a third locking device 25 which has two essentially straight arms 26 is executed. Bores 27 are machined in the cover 10, while recesses 28 are recessed in the frame, which have a direction deviating from the direction of the bores 27. As can be seen from FIG. 14, the depressions 28 are inclined towards one another. If the locking device 25 is now used, a frictional connection between the arms 26 and the walls of the recesses 28 is created in the recesses 28. The cover 10 is thus held in the frame 8 by a frictional connection. So that the depressions 28 can be provided in the frame 8, the inner flange 9 of the frame 8 is formed at this point in a different way, so that an interrupted part 29 is formed which interact with interrupted parts 30, 31 of the cover or grate.
  • FIG. 16 the difference compared to FIGS. 13 to 15 is that the depressions 28 diverge.
  • the frictional connection between the arms 26 and the depressions 28 is created by the elastic deformation of the arms 26.
  • a fourth locking device 35 is shown on the Haitekopf 2 .
  • a straight arm 36 is attached, which has a curved portion 37.
  • the fourth locking device 35 is shown in the assembled state.
  • a bore 38 is provided in the lid 10, to which a recess 39 in the frame 8 connects, which is substantially aligned with the bore 38.
  • the frictional connection is produced by the curved section 37 and the side walls of the depressions 39.
  • a fifth locking device 40 is shown. It also has a single arm 41, which has a curved portion 42.
  • the difference from the fourth locking device 35 is that the arm 41 is firmly connected to the cover 10. It can even be an integral part of the cover 10. The frictional engagement occurs between the walls of the recess 43 in the frame 8 and the curved part 42 of the arm 41 arranged in the cover 10.
  • the arm 41 can be longer, as in FIG. 21, and protrude from the recess 43 below.
  • the locking devices 1, 20, 25, 35, 40 described can be made of steel, ductile cast iron and plastic.
  • the same materials can also be used for the production of the parts of the cover 7, i. H. the lid 10 or the grate and the frame 8 can be used.
  • the materials must be capable of being deformed elastically to such an extent that they can withstand the deformations during assembly and when installed.
