Definitions

  • the invention relates to a locking device for gates, doors, leaves, drawers and the like, and of the kind disclosed in the preamble to claim 1.
  • Known closing elements for such applications are designed in such a manner that use must be made of tools or keys in order to close a leaf, or manual use must be made of thumbscrews or the like before the leaf can be closed.
  • the object of the invention is to present a locking device which is arranged in such a manner that when the leaf or the drawer is pushed in, an automatic closing and tensioning occurs during the last phase of the closing.
  • the locking .device according to the invention is characterized in claim 1.
  • a leaf or a drawer with a locking device ac ⁇ cording to the invention is closed, i.e. against the frame or post with retaining element according to the invention, the energy stored up in the mechanical energy store is released and the bolt enters into firm and solid engagement with the tracks in the re ⁇ taining element, and can only be led out of engage ⁇ ment herewit by turning the handle, but e.g. not by a strong compressive force, for instance from an ex- plosion or arc in the area enclosed by the leaf.
  • the energy store which will usually be a steel spring, will be automatically tensioned when the leaf or the drawer is opened in the correct manner by means of the handle.
  • the locking device according to the invention can be configured as characterized in claim 2, whereby a secure activation of the closing of the leaf is ach ⁇ ieved, in that the closing is not initiated until the leaf is almost completely in place against the frame or the doorpost.

  • the release element in the locking device according to the invention is preferably configured as char ⁇ acterized in claim 5, in that the release element is hereby given an additional function, namely to ensure that when the leaf is opened by means of the handle on the outside of the cabinet, one cannot avoid the spring being given sufficient tension, in that the leaf cannot be opened until the spring is tensioned and the release element is held in engagement with the edge of the opening in the lock housing.
  • the retaining element in the locking device is pref ⁇ erably configured as characterized in claim 6, in that it hereby supports the release element so that it has limited possibility of movement and cannot be ruined, not even by violent opening or closing of the leaf.
  • the release spring will remain unaffected when the leaf is cor ⁇ rectly closed, so the spring is not ruined or deform ⁇ ed by a constant influence.
  • the release spring is given an additional function, ,in that it contributes towards ensuring that the stag- gered part of the release mechanism enters into pos ⁇ itive engagement with the opening when the leaf is opened, because the release spring pulls and holds the release element against that part of the housing in which the opening is placed.
  • the locking device according to the invention is preferably configured as characterized in claim 9, in that this provides the possibility of assembling and holding the parts together in a simple and practical manner while providing a strong construc ⁇ tion which can enter into very solid engagement with the retaining element.
  • the locking device according to the in ⁇ vention can be used in many places, it has been de ⁇ veloped especially for use in connection with leaves, such as covers, doors, gates, drawers etc. in plate -enclosed electrical units for heavy current, as dis- closed in claim 10.
  • leaves such as covers, doors, gates, drawers etc. in plate -enclosed electrical units for heavy current, as dis- closed in claim 10.
  • Security is hereby provided that the closing of the leaves always takes place in such a manner that they cannot spring open, even though an arc should occur behind said leaves, but they can still be opened by means of the handle for repair work and inspection, possibly without the use of tools.
  • fig. 1 shows a smaller plate-enclosed electrical unit for heavy current
  • fig. 2 shows the locking device according to the invention, mounted on a door which is hinged on a post with a retaining element
