Definitions

  • the present invention relates to an adapter for a locking device having a first handle configured to operate a first bolt operating mechanism of a locking device and a second handle configured to operate a second bolt operating mechanism of the locking device.
  • the invention also relates to a locking assembly comprising a locking device and such an adapter.
  • adapters may be used as separate components that are added to an existing locking device in order to alter functions of the locking device with only minimal modifications to the locking device itself.
  • One type of such adapters is used as emergency exit devices and are mounted on the locking device on the inside of a door to enable evacuation. Often, it is desirable to allow evacuation from inside of a building while at the same time preventing undesired entrance from outside.
  • This type of adapter has two separate handles, one that is used in normal operation for operating one bolt of the locking device for opening a door that is not locked. Unlocking the door can take place by using a key or an electromechanical activation such as a keycard or tag that activates a motor for unlocking another bolt. However, for evacuation purposes another handle is sometimes provided that is able to operate both of the bolts.
  • a problem with existing solutions within this field is that evacuation may be hindered when a person using the door also pushes on the door, causing a load on the locking device, or when one of the handles is blocked.
  • the transfer of forces from the adapter to the locking device may in such cases jam the locking bolt so that retracting the bolt is rendered difficult or even impossible.
  • the object of the present invention is to eliminate or at least to minimize the problems discussed above. This is achieved by an adapter, an adapter assembly and a locking assembly according to the appended independent claims.
  • an adapter for use with a locking device has a first bolt with a first bolt operating mechanism and a second bolt with a second bolt operating mechanism.
  • the adapter comprises an adapter body, a first handle mounted in a first part of the adapter body and arranged to operate the first bolt operating mechanism of the locking device, and a second handle mounted in a second part of the adapter body and arranged to operate the second bolt operating mechanism of the locking device.
  • the adapter further comprises a transmission mechanism for transmitting a rotational movement from the first handle to the first bolt operating mechanism.
  • the transmission mechanism comprises a first coupling member rotationally fixed to the first handle and provided with a first engaging member, and a second coupling member arranged to be rotationally fixed to the first bolt operating mechanism and provided with a second engaging member and an override member.
  • the first engaging member is arranged in relation to the second engaging member so that the first engaging member rotating in a first rotational direction will engage with the second engaging member and bring the second coupling member into rotation.
  • the second coupling member rotating in the first rotational direction will however not bring the first coupling member into rotation.
  • the adapter further comprises an override mechanism connected to the second handle and arranged to be activated by the rotational movement of the second handle and upon activation engage with the override member of the second coupling member and bring the second coupling member into rotation in the first rotational direction.
  • the adapter has the main advantage that the first handle can be operated to control both the first bolt operating mechanism and the second bolt operating mechanism of a locking device with an efficient transfer of forces and while preventing any blockage of the second handle from hindering this operation. Due to the clearance provided in the transmission mechanism, the first bolt causes a smooth transfer of force to the second bolt operating mechanism of the locking device regardless of a position or state of the second handle so that evacuation is always possible using only one single action. This in turn renders the adapter both safer and more stable than existing solutions within this field.
  • the override mechanism comprises a first transfer element fixed to the second handle and at least a second transfer element connected to the first transfer element and arranged to engage with the override member.
  • the second transfer element is arranged to upon activation by the first transfer element move a first distance without engaging with the override member and after moving the first distance arranged to engage with the override member to bring the second coupling member into rotation.

  • the second handle may be arranged to engage directly with the second transfer element instead of with the first transfer element. This provides for an flexibility in the design of the adapter.
  • the adapter may also be used in situations where a push bar is considered more appropriate than a handle, and by the push bar also being rotatably arranged the operation of the adapter may be realized without requiring substantial structural modifications.
  • the override member of the second coupling member is arranged in relation with the second transfer element so that second coupling member may rotate at least a distance in the first rotational direction without the override member engaging with the second transfer element.
