Definitions

  • the invention relates to a locking device which is intended to hold a lid or grate in a frame in a form-fitting manner.
  • a cover which essentially consists of a cover or grate which is mounted in a frame.
  • the term "frame” is not only understood to mean frame-like supports for the cover or the grate, but also all designs of edges which serve to support the cover or the grate.
  • one or more lids or grids are placed in a frame, generally no device for holding the lid in the frame is provided. Since the lids and grids have been made relatively heavy, there is no particular need to hold them in the frame.
  • lids and gratings have been improved in design and / or made of a more resilient material, e.g. B. made of ductile cast iron instead of ordinary cast iron, which led to a lighter design. Because such lids or grids have greater elasticity have the need to provide brackets with which the lid or the grids are held in the frame.
  • a locking device which can be used in the lid or in the grate is used, parts of which interact with parts of the frame in such a way that a positive or frictional connection, possibly connected with a blocking possibility, is formed with these parts and parts , which creates a reliable mounting of the lid or the grate, albeit with some play.
  • this older locking device cannot hold the lid or the grate in the frame with a pretensioning force.
  • a locking device with a locking member which is provided with at least two interconnected arms, at the connection point of which a support rod projecting from the arms is arranged with a storage and actuating device and is firmly connected to the arms. This ensures that the arms can be used to pretension the cover in the frame.
  • the invention therefore also includes a cover or grate and a frame, the task of which is to enable the locking device according to the invention to be pretensioned.
  • the invention is based on the consideration that the locking device should be designed in such a way 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 2.
  • 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 13 and firmly with one another are connected.
  • a support rod 14 is firmly 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.
  • two guide links 20 are arranged which, as can be seen from the secondary figure a), have an inclined flank 21. At the end of the inclined flank 21, a latching recess 22 is provided, into which the arm 12 engages when the locking device 10 is in the closed position.
  • the arms 12 are elastically bent during their rotational movement along the inclined flank 21, and thus exert a prestressing force on the cover 2; the cover 2 is thereby immovably pressed onto the inner flange 3, so that it is not moved out of its position even when loaded by strongly changing loads.
  • the number of guide links 20 also increases; a guide link 20 is to be provided for each arm 12.
  • the cover formed from the frame 1 and the cover 2 has a relatively small diameter. For this reason, the pressing of the cover 2 onto the inner flange 3 can be achieved with a single locking device 10.
  • a cover 2 is shown with a relatively large area, as is necessary for shafts and for entry and exit openings.
  • three, four or more locking devices 10 are provided. Two of these locking devices 10 are shown in FIG. 2. They are designed exactly the same as the locking device 10 according to FIG. 1, which is why they are no longer described in detail.
  • the arms 12 of the closing member 11 are also elastically bent in the guide slots 20.
  • a difference in this embodiment is that not all of the arms 12 are supported on the inner flange 3, as is the case in the embodiment according to FIG. 1, but a part of the arms is supported on guide links 20 which are on the inside of the cover 2 are molded. But even in this case, the pressing of the lid on the inner flange 3 is reliably achieved.
  • FIG. 3 shows a second embodiment 25 of a locking device.
  • arms 24 are provided in the form of a turn, the ends of which are guided on a guide link 30 of the inner flange 3.
  • the guide link 30 is designed as an inner circumferential ring surface with a decreasing diameter. This means that when the locking device 25 is rotated into its closed position, the arms 24 of the locking member 26 are compressed and thereby elastically deformed. In this case too, a preload is created in the locking device 25, with which the cover 2 is held in the frame 1. In the end position, i.e. H. in the closed position of the locking device, the arms 24 also snap into a locking recess 32, see the secondary figure b) of FIG. 3.
  • FIG. 5 A third embodiment 35 of a locking device is shown in FIG. 5.
  • Your arms 34 are in contrast to the arms 12 and 24 in Fig. 1 and 3 bent 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. 3 and, on the other hand, an elastic bending deformation corresponding to the embodiment according to FIG. 1 takes place.
  • Such a latching recess 38 is also provided in the embodiment according to FIG. 5, see the secondary figure c) of FIG. 5.
  • the latching recesses 22, 32, 38 of the locking devices according to FIGS. 1, 3 and 5 have the purpose of the arms 12, 24, 34 not only to be held in a frictional engagement, but also in a positive engagement, so that removing the locking device from the closed position requires a certain amount of force.
  • FIG. 4 shows a similar arrangement of locking devices 35 as shown in FIG. 2.
  • 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, 3 and 5 would be unsuitable, since it would have to be made more solid and would therefore require a greater expenditure of material.
  • locking devices 24 could also be used.
  • the corresponding guide link 30 would then also have to 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. 6.
  • the arms 12 are designed as straight rods. However, instead of straight bars, curved bars 12 could also be used, the bending of which, however, lies in a horizontal plane, see FIG. 6. The function of the locking device remains the same as in FIG. 1.
  • the winding or curved arms 34 could also be placed in a horizontal plane without the function of the locking device 35 changing as a result.
