Definitions

  • the invention relates to a retractable closure for control cabinet doors or the like, with a locking part which has a sash for central locking and / or rods extending upwards or downwards from the locking part for upper or lower locking of the door, the locking part being a through the door leaf leading to the outside actuating shaft, to which a handle in the form of a handle lever is attached, which is pivoted at one end to the actuating shaft about an axis perpendicular to the actuating shaft axis, and at the other end in the closed state in the direction of
  • a receptacle for a lock such as a cylinder lock or the like.
  • Provided projection, and wherein a plate-like attachment or plate is provided on the door leaf, which has a recess corresponding to the projection for the lockable receiving of the projection, which the door leaf plane inwards pierces.
  • Locks for control cabinet doors or the like are already known in many variants, see for example the German utility model 7 621 270.
  • Such closures are usually provided with a toggle handle, which can also be removable to prevent unauthorized opening.
  • a disadvantage of such a door lock is that replacement handles can be obtained fairly easily and the cabinet can then be opened by an unauthorized person, so that the actual security purpose is missed.
  • the handle has been given the shape of a handle lever, which at one end on the actuating shaft is perpendicular to the shaft axis Axis is pivotally articulated and has at its other end a in the closed state in the direction of the door leaf, provided with a receptacle for a cylinder lock or the like.
  • Projection is provided on the door leaf, which has a recess that fits the projection to the closable Receiving the projection has, as described in a similar manner from DE-GM-7 014 950.
  • the lock can be secured by means of a regular lock, such as a cylinder lock, so that the lock has the same level of security against unauthorized opening as other doors which can be locked by means of cylinder locks or the like.
  • the object of the invention is to provide a retractable closure for control cabinet doors or the like.
  • the type described above which avoids these disadvantages.
  • the depression of the plate-like attachment has a substantially circular outer cross section and has a circumferential thread; the plate-like attachment is formed in one piece with the bearing housing of the actuating shaft, and the bearing housing of the actuating shaft has a part penetrating the door leaf plane inwards, which has a circular, if necessary provided with constrictions, external cross-section and an external thread, so that the plate-like attachment is screwed on at two points Fastening nuts can be fastened.
  • a circular opening is provided in the door leaf for the bearing of the actuating shafts and for the projection receiving the cylinder lock or the like, and bearings or inwards penetrating projection can be provided with an external thread, on which a correspondingly suitable screw nut is placed, in order in this way to fix the closure on the door leaf.
  • this results in a particularly secure and simple attachment on the other hand, it can also be carried out in a very simple manner, for example, to make the area on one side of the door leaf watertight, dustproof and airtight in that the projection penetrating through the door leaf plane is fastened with the aid of an internally threaded cup.
  • this cup consists of insulating material, for example of insulating plastic, at the same time a further protection against the spread of voltage on the mostly metallic cylinder lock is achieved in a simple manner.
  • the tightness can be improved by using seals such as O-ring seals or sealing sheets in the form of the contact surface for the outer parts of the closure.
  • the closure is to be used for walk-in cells, it is expedient, according to yet another embodiment of the invention, the closure with a panic lock device in the form of a freewheel provided, for example, between the closure part and the actuating shaft. B. 90 °, such that the closure can be opened from the inside even when the outer handle is locked.
  • closure according to the invention can also be used to fasten a rod lock, provided that it is provided with a lining that rests on the inner surface of the door leaf, because then with the help of the screw nut fastening the lock, the rod closure relining could be held.
  • FIG. 1 shows a rod lock 10 which locks the door 16 to the door frame 36 with the aid of rods 28, 30, the rods being guided near the ends in a suitable manner, for example by means of rod guides 40 on the door 16.
  • FIGS. 2 and 3 are a front view and a view play from above on the closure of FIG. 1.
  • the closing part 12 of the closure 10 is of relatively simple construction and essentially consists of an actuating shaft 14 leading through the door leaf 16, which is rotatably mounted in a bearing housing 18 through at least 90 °, wherein the rotation angle limitation is effected, for example, by means of a nose (not shown in more detail) at the inner end of the actuating shaft 14, which strikes against stop surfaces 20, 22 of the bearing housing 18.
  • This inner end of the actuating shaft 14 also carries a double-armed lever 24, at the free ends of which an actuating rod 28 or 30 is articulated.
  • the lever 24 can merge into the cam 32 in one piece.
  • the housing 18 has an external thread 26 for a fastening nut 27 for screwing the housing 18 after the housing 18 has been pushed through a corresponding opening in the door leaf 16.
  • a handle 38 in the form of a handle lever is articulated at the outward end of the actuating shaft 14 by means of a pin 34 in such a way that the handle lever 38 can be pivoted to an axis perpendicular to the shaft axis.
  • the bearing housing 18 also has an outwardly opening trough 42 with an approximately hemispherical profile, in which the appropriately hemispherical end surface of the handle 38 is suitably inserted. In this way, the handle 38 can be pivoted both about the axis of the pin 34 and rotated about the axis of the actuating shaft 14.
  • a projection 44 which, in the closed position of the handle 38 shown in FIG. 1, points in the direction of the door leaf 16 and is received by an attachment 46 which extends inwards through a corresponding opening in the door leaf 16.
  • This inwardly extending part of the attachment 46 forms a depression 45 with a circular outer cross-section and an external thread 48, onto which a nut similar to the nut 27 or, as shown, an internally threaded cup-like nut 50 can be screwed on, so that an under Circumstances gas, dust or moisture-tight closure of the opening in the door leaf 16 results.
  • the height of this cup nut 50 should not be greater than the distance of the rod 28 from the door leaf 16, otherwise the Attachment 46 could not be mounted in the area of the rod 28, as is the case with the embodiment according to FIGS. 1 to 3.
  • Other types of attachment of the cup to the depression would be equivalent to screwing the cup 50 on, but these are less convenient to handle.
  • the lower end of the handle 38 also has a receptacle 52 for a cylinder lock 54 or the like, the locking finger 56 of which, when closed by means of a cylinder key, comes into a path with a stop surface 58, which pulls the projection 44 out of the attachment 46 in a known manner prevented.
  • a plate 60 which can be placed on the door leaf 16 and which at its one end, as shown in FIG. 1, into the bearing housing 18 and at its top other, lower end in one piece in the attachment 46.
  • the plate 60 could be screwed onto the door leaf 16 by means of a countersunk screw or the like, not shown here, or else welded or glued on.
  • the attachment of the plate 60 is effected in that on the one hand the bearing housing 18 is fixed by means of a nut 27 and on the other hand the depression 49 penetrating the door leaf plane inwards is fixed by means of the cup nut 50.
  • cup nut 50 forms a tight seal with the door leaf 16, because this prevents the passage of harmful gases, moisture and dust through the opening formed in the door leaf 16 for the depression 45, specifically that for both directions.
  • This tight seal could be achieved, for example, by producing the cup nut from a plastic material which is somewhat flexible at least in the edge area, the edge of the cup nut 50 resting on the door leaf 16 also having a flexible lip (not shown) for additional sealing.
  • FIG. 4 Another possibility would be the interposition of a sealing sheet 47, see FIG. 4, between the outer surface of the door sheet 16 and the contact surface of the plate 60 or the plate-like attachment 46, the sealing sheet 47 having the same hole pattern as the door sheet.
  • the handle 38 and the plate-like attachment 46 are made of plastic material, because for reasons of stability the actuating shaft 14 and the cam tongue 32 attached to it (as well as the double-armed lever 24 with the rods 28 attached to it) 30) is made of metal and therefore, if the handle 38 were also made of (electrically conductive) metal, a carry-over path would again be available for dangerous electrical voltages to the outside.
  • annular groove 62 for receiving a sealing ring and also within the bearing housing 18 could have a corresponding groove for receiving an O-ring seal 64 may be provided.
  • FIG. 4 shows, in a view similar to FIG. 1, another embodiment of the control cabinet door lock according to the invention, the lock 10 here having a somewhat more complicated shape with removable bars 28, 30, a bar lock relining 66 and a panic device 78.
  • the relining 66 ensures secure storage of the closure 10 even in this heavier embodiment, while at the same time providing a sufficient distance for the closure 10 and thus the rod 28, 30 from the door leaf 16, which in view of the inwardly projecting parts of the plate-like attachment 46 is appropriate.
  • a similar relining is also shown in the embodiment shown in FIG. 5, however the relining 66 there is not fastened to the door leaf, for example, by means of special screws (not shown) or welded, but is held by the nut 27, which also supports the bearing housing 18 and thus holding the plate-like attachment 46 of the closure according to the invention.
  • the relining 66 is provided with a bracket plate 68 spanning the area of the bearing housing 18, which has a breakthrough similar to that of the door leaf 16 for the bearing housing 18, so that after the nut 27 is screwed on, the bracket plate 68 comes to rest firmly on the door leaf 16 .
  • this can be bent perpendicularly away from the door leaf plane 16 on one side, see reference number 70.
  • this fastening hole for a conventional sash lock was already provided in the manufacture of the door leaf.
  • this fastening hole is provided with at least one, usually four tendon-like constrictions, to which the outer circumference of the push-through part of the closure is adapted.
  • FIGS. 4 and 5 show very clearly the panic device which serves to be able to open the closure 10 from the inside even when the closure is locked from the outside by inserting the projection 44 into the attachment 46, so that someone accidentally locked in a walk-in control cabinet can free himself again. He can do this by actuating a lever 72, which is mounted on a square actuating shaft 74 projecting from the closure part 10 in a rotationally rigid manner.
  • This actuating shaft 74 directly actuates the rod lock 10 with the rods 28, 30 and the sash and exits again on the other side of the lock box 10 in order to open there in a freewheel device 80, consisting, for example, of a first one with the square Actuating shaft 74 torsionally rigid coupling disc 82 and a second with the actuating shaft 14 for the handle 38 torsionally rigidly connected second coupling disc 84.
  • one coupling disc 80 is provided with one or two projections which engage in corresponding guide grooves in the other coupling disc with limited angular extent, can achieve that the two disks 80, 84 are mutually displaceable by, for example, about 90 °, such that the rod lock 10 can be opened and closed by means of the lever 72 without the actuating shaft 14 of the handle 38 having to rotate.
  • the closure 10 can also be closed and opened by rotating the handle 38 by, for example, 180 ° (with a free-running angle of 90 °).
  • a normal metal nut similar to the nut 27 can also be used for fastening the depression 45, provided that the projection 44 locks the cylinder lock 54 cup-shaped shape.
  • a lateral slit-shaped opening in the cup-like projection 44 would then have to be provided, so that the thumb 49 can pass through and swivel into the closure track 58 (FIG. 1) of the attachment 49 and lock the lever 38.
  • the (metallic) thumb 49 is insulated from the depression 45 of the plate-like attachment 46. However, the slot causes a leak.
  • the retractable closure described above is particularly advantageous for sheet metal doors when it comes down to the cheap two-hole fastening and the tightness. It is of secondary importance whether a cylinder key is used for locking (as shown) or the square, triangular and similar keys that are also used with the normal cam locks.
  • the lock In the case of plastic cupboards for electrical systems, the lock should be insulated in the manner described, since it is not possible to ground the lock via the door leaf, which is made of insulating material, and a special grounding device is too expensive.
  • the closure of the invention thus allows not only a stable and rotatable two-hole fastening in a simple manner, but also a seal without expensive additives and also a protective insulation of the closure against z. B. loosened, live wires inside the cabinet.
