Definitions

  • the present invention relates to an adapter for a lock case for opening a locked door without a key or a locking knob.
  • the present invention relates to an adapter to be connected to a lock case for always allowing a person to open a door from the inside without a key, a knob or a handle, even if said door is locked.
  • split spindle system which is arranged to disengage the inner handle from the outer handle in such way the door may be opened from the inside even though it is locked from the outside.
  • split spindle solution may be utilized such that the inner door handle always is connected to the lock bolt, whereby the outer door handle is disconnected from the lock bolt.
  • One disadvantage is that the installation of the split spindle system usually is made in extremely small or narrow areas or surfaces inside the lock case, which areas and/or surfaces may get worn out if the door is constantly used; doors in schools are one example. When the split spindle gets worn out the entire system may stop working and the door may not be opened. Such damage will result in the inner door handle to always be disengaged from the lock bolt which means that if the door is locked, a person entrapped inside the door will have no possibility to exit.
  • split-spindle system operates on small and narrow surfaces it may be complicated to install the system, for new installations as well as when it needs to be replaced or maintained.
  • An object of the present invention is to provide a new adapter for a lock case, which is improved over prior art. This object is achieved be a technique defined in the appended independent claims; certain embodiment being set forth in the related dependent claims.
  • an adapter for a lock case including a handle unit to be connected to a door handle and arranged to be rotated about a first axis when the door handle is pushed down or pulled up for moving a latch bolt in and out from said lock case.
  • the adapter further includes a lock unit to be connected to a lock follower extending through said lock case and arranged to rotate about a second axis for moving a lock bolt in and out from said lock case.
  • the handle unit comprises an end portion and the lock unit comprises an end portion which are engaged with each other in such a way that when the handle unit starts to rotate about the first axis the lock unit starts to rotate about the second axis.
  • the adapter includes a first cover portion and a second cover portion, where the first and second cover portion in an assembled state are configured to enclose the handle unit and the lock unit.
  • the adapter further has a lock washer connected to the outside surface of at least one of the first and second cover portions opposite the connection between said handle unit and the door handle.
  • the adapter is adapted to be arranged on one side of a door, between a door leaf and the door handle. This is advantageous when the adapter is used on a door which is used as e.g. an emergency door or a hotel door where it is necessary and desired to be able to open the locked door and get out.
  • the adapter is adapted to be detachable from said door which is advantageous since it is possible to then post-install the adapter to a door which is already installed.
  • end portions of the handle unit and the lock unit are in constant contact with each other. Since the lock unit always is in contact with the handle unit the adapter never has to be switch on to function.
  • the handle unit is biased such that it automatically returns to an idle state, corresponding to a horizontally aligned position of the door handle, when a force pushing down or pulling up the door handle has been released. This is as above also an assurance that the door is always locked except for when the handle is pushed down, which is advantageous for e.g. emergency doors.
  • the adapter further comprises an indicator configured to indicate an active and/or inactive state of said adapter, which is advantageous since it provides a clear indication whether the adapter is able to accomplish its function.
  • a door lock assembly for mounting to a door leaf, comprising a lock case including a latch bolt to be operated by at least one door handle connected to a door handle follower of said lock case, a lock bolt in connection with a lock follower of said lock case, and an adapter as described above, connected to said lock case.

  • An advantage with the present adapter is that it may be used on existing lock cases with no split spindle functionality.
  • the present adapter may, together with such lock case without split spindle, replace spilt spindle lock cases for improving the reliability of the door lock thus always allowing persons on the inside of the locked door to exit the door.
  • the adapter may include an indicator (not shown) which is configured to indicate an active and/or inactive state of the adapter.
  • the active state is when the components of the adapter are able to interact with each other so that locked door opens if the handle on one side is pressed down.
  • the indicator is preferably an electrical indicator which indicates the active and/or inactive state with light, sound or movement. In an alternative embodiment it could be a mechanical indicator.
