Definitions

  • the invention relates to a cam lock for a Door or flap, especially of control cabinets or the like, with one on the door leaf or the flap fixed housing and rotatable with one in the housing arranged actuation shaft, the confirmation shaft on the outside of the door with a locking mechanism such as a handle, Cylinder lock or the like can be coupled and inside the door is rigidly connected to a sash tongue, by rotating the actuating shaft between one Unlocking position and a locking position for the door or flap is movable.
  • a cam lock for a Door or flap especially of control cabinets or the like
  • Cam lock with the aforementioned features is described in EP 0 504 144 B1.
  • Cam lock is one on the outside of the door free end with a toggle handle as actuation provided actuating shaft rotatably mounted; on her the other, inside the door carries the actuating shaft a serrated tongue connected to it by turning Rotation of the toggle handle between one Unlocking position and a locking position for the door is movable.
  • the sash tongue lies down for example behind a bend in the cabinet body and this keeps the door closed.
  • the known Cam lock is based on the material thicknesses and Form relationships of cabinet body and door leaf like this adjusted that with the door closed and in the Locked position of the turned cam tongue a fixed and permanent closure of the cabinet is guaranteed.
  • Control cabinets determine what after an explosion occurring inside the control cabinet with corresponding pressure development the door temporarily should stand out from the cabinet body in order to over a so resulting gap to relax the explosion pressure without for example, people standing in front of the closet endanger violent full door opening. To Relief of the explosion pressure is said to be in the door must be essentially unlockable normally.
  • the invention is therefore the task of one under the Control cabinet prevailing internal pressure a gap Door lock that allows the door to be opened to deliver.
  • the basic idea of the invention provides that due to a longitudinally displaceable arrangement of the Actuating shaft in the housing a relative displacement of the housing in the locked position Sash tongue fixed actuation shaft is enabled and that in mutual support between Actuating shaft and housing a relative displacement yielding element is arranged. If so on that Door leaf with attached housing, for example an explosion occurs an outward pressure is exercised, the housing can oppose the through the one in the locked position Locking tongue held actuating shaft relatively move so that the distance between the housing and Enlargement tongue and enlarge the door despite locked sash tongue around a constructive set displacement corresponding dimension of the Cabinet body can lift off. Let him on the door pressure after, the sash lock is through Turn the actuating shaft to the unlocked position bring the sash tongue so that the door is normal can be opened.
  • the compliant element from one material deforming under load; the deformation the yielding element must be the required Displacement of the housing in relation to the actuating shaft provide.
  • the compliant element is a material that can be destroyed under load required displacement due to the disappearance of the yielding element easily adjustable.
  • the compliant element is designed as a resilient component. This is the Advantage associated that after the acting Pressure the tensioned spring relaxes again while doing so leads to the door being closed again by the The sash lock can also be easily opened and closed is because the resilient element itself under the built-in cam lock no preload unfolded. It may be appropriate that the yielding element as on the actuating shaft plugged spring sleeve is formed.
  • the inside of the door of the actuating shaft 13 has a square neck 14 on which a sash tongue 15th is plugged with a square recess 16 so that there is a torsionally rigid connection between the actuating shaft 13 and sash tongue 15 results.
  • the sash tongue 15 is on the actuating shaft 13 by means of an axial screwed fastening screw 17 connected, the has a locking toothing 18 on the end face, so that a Self-loosening of the fastening screw 17 is avoided.
  • On the sash tongue 15 is formed a projection 26 which into a groove 27 of the housing 10 which extends over 90 ° intervenes, thus limiting the turn of the sash tongue 15 compared to the housing 10 is realized.
  • the Element 20 On the actuating shaft 13 is a sleeve-like element 20 attached, which is at one end against the Actuating approach 12 supports the actuating shaft 13 and with its other end against a spacer 19 of the Housing 10 is supported, so that from a destructible material existing element 20 between the Housing 10 and the actuating shaft 13 is clamped.
  • the Element 20 consists of a destructible under load Material, for example a suitable ceramic material.
