Definitions

  • the present invention relates to an adapter for a locking device having a first bolt operated by rotation of a first shaft and also having a second bolt, the adapter comprising
  • a first connector configured to be connected to a first shaft of a first handle unit such that a rotation of the first shaft causes a rotation of the first connector
  • a second connector configured to be connected to a second shaft of a second handle unit such that a rotation of the second shaft causes a rotation of the second connector
  • 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 an inside of a building while at the same time preventing undesired entrance from outside.
  • a problem with existing solutions within this field is that evacuation is sometimes hindered when a person using the door also pushes on the door, causing a load on the locking device.
  • 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 desired functions can be achieved simply by using the adapter so that both unlocking and opening of the door may be caused by a single action of a user.
  • There is also a need for an emergency exit device that is always able to unlock and open a door when needed and that still prevents unauthorized access from an outside of the door.
  • the object of the present invention is to eliminate or at least to minimize the problems discussed above. This is achieved by an adapter and a locking device comprising such an adapter according to the appended independent claims.
  • An adapter according to the invention is suitable for a locking device having a first bolt operated by rotation of a first shaft and also having a second bolt.
  • the adapter comprises
  • a first connector configured to be connected to a first shaft of a first handle unit such that a rotation of the first shaft causes a rotation of the first connector
  • a second connector configured to be connected to a second shaft of a second handle unit such that a rotation of the second shaft causes a rotation of the second connector
  • the coupler comprises a first engaging member arranged on the first connector and a second engaging member arranged on the second connector, said first engaging member and second engaging member being arranged in the coupler so that a rotation in a first direction of the second engaging member is transferred to the first engaging member to cause a rotation of the first connector, whereas a rotation in the first direction of the first engaging member is not transferred to the second engaging member, and wherein the coupler further comprises an activation unit for operating the second bolt, wherein the activation unit is arranged in the coupler so that a rotation of the second engaging member in the first direction causes an activation of the activation unit.
  • the locking device is modified through the adapter so that a handle on one side of the locking device (corresponding to an inner side of a door) can be used both for unlocking the door through the activation unit operating the second bolt and for opening the door through the first shaft operating the first bolt.
  • a handle on the other side of the locking device (corresponding to an outer side of the door) can be used only for operating the first bolt to open the door but cannot operate the second bolt for unlocking.
  • the present invention provides an adapter that modifies a conventional locking device so that different functions on different sides of the door are achieved.
  • a significant benefit of the present invention is that both unlocking and opening of the door is made through one action only (namely pivoting the second shaft by operating a handle on the inner side of the door) which enables emergency exit from the inside in a secure and reliable way.
  • the rotation in the first direction is transferred in the coupler to the first engaging member by a leading surface of the coupler engaging a first contact surface on the first engaging member.
  • a secure transfer of rotational force from the coupler to the first engaging member is achieved.
  • the second engaging member may suitably comprise the leading surface so that the second engaging member contacts the first engaging member directly.
  • the number of components can be kept low while at the same time achieving a stable and secure transfer of rotational force from the second shaft and the second engaging member to the first engaging member and the first shaft.
  • the coupler may comprise a coupling element that comprises the leading surface
  • the second engaging member may comprise a second contact surface that engages with a meeting surface of the coupling element so that a rotation in the first direction of the second engaging member is coupled to the first engaging member via the coupling element.
  • the rotational force is coupled from the second engaging member to the first engaging member by a coupling element that is also rotated.
  • the rotational force can thus be coupled to the coupling element that may in turn have additional functions where the rotation is used to operate the second bolt, among others.
  • the first engaging member may also comprise a leading edge and the coupler may be configured with a play that allows the first engaging member to rotate in the first direction without the leading edge contacting a meeting surface in the coupler.
  • the coupler may be configured with a play that allows the first engaging member to rotate in the first direction without the leading edge contacting a meeting surface in the coupler.
  • one of the first engaging member and the second engaging member could alternatively comprise the play so that the first engaging member is able to rotate freely in the first direction without the leading surface contacting a meeting surface of the second engaging member. This is suitable where it is desired to keep the number of components low while at the same time achieving a stable and reliable adapter.
  • the coupler comprises a coupling element that comprises the play so that the first engaging member is able to rotate freely in the first direction without the leading surface contacting a meeting surface of the coupling element. This is suitable where a coupler is used to couple rotation from the second engaging member and still achieves the stable and reliable operation of the adapter.
  • At least one of the first connector and the second connector is/ are configured to be connected to a first or second shaft by the first connector and / or the second connector comprising an indentation into which an end of a first or second shaft can be inserted.
  • shafts can be connected to the connectors in a simple and advantageous way so that rotation can be transferred from the shafts to the respective connectors in an easy and reliable way.
  • the activation unit may in a mechanical connection to the operation of the second bolt comprise a first activation arm that is integrated with the coupler and a second activation arm for operating the second bolt, said first activation arm being configured to move the second activation arm in response to a rotation of the second engaging member.
  • rotation of the second shaft and second engaging member may be reliably transferred by means of the first and second activation arm so that the second bolt may be operated in response thereto.
  • the second activation arm comprises a first portion for interaction with the first activation arm
  • first activation arm is configured to rotate the second activation arm by contacting and moving the first portion to achieve a corresponding rotary movement of the second portion for operating the second bolt.
  • first portion of the second activation arm may have a first length and the second portion of the second activation arm may have a second length, wherein the second length is larger than the first length, preferably at least twice as large, more preferably at least five times as large and even more preferably at least ten times as large.
  • the activation unit comprises a non-mechanical activation unit for operating the second bolt
  • the coupler also comprises an actuator portion such that a rotation of the second engaging member in the first direction causes the actuator portion of the coupler to contact and thereby activate the activation unit.
  • a mechanical activation of the adapter through a rotation of the second shaft and the second engaging member also achieves a non-mechanical activation of the second bolt so that it is unlocked.
  • Such non-mechanical activation may thus be an electrical activation by operation of an electrical motor or may alternatively be a magnetic or electromagnetic activation.
  • the activation unit is a microswitch.
  • the non-mechanical activation also comprises a second bolt operator that is configured to extend and / or retract the second bolt in response to an activation signal, and the activation unit is also configured to generate and send such an activation signal when the activation unit is activated by the actuator portion.
  • the unlocking of the second bolt through non-mechanical activation is achieved through the single mechanical action of rotating the second shaft, making the configuration of the locking device even more versatile since any kind of second bolt operator may be used with the adapter of the present invention. It is also compact and space-saving so that the adapter may be used with smaller locking devices or with locking devices that already have many additional components inside.
  • the second bolt operator may be arranged in a locking device and the adapter may be mounted in connection with said locking device.
  • the second bolt operator may be arranged in connection with a strike plate that is arranged for receiving the second bolt.
  • the non-mechanical activation unit is also configured to operate a remote mechanism.
  • the remote mechanism can be a locking device that is separate from the locking device on which the adapter is mounted or a strike plate configured to cooperate with such a separate locking device.
  • the remote mechanism can be a mechanism that is not connected to or configured to cooperate with a locking device, such as a fan or a light source.
  • the non-mechanical activation unit can act to operate the second bolt and at the same time to also operate another locking device or a light source or fan that are in a vicinity of the adapter.
  • the present invention also comprises a locking device that in turn comprises an adapter according to the invention.

  • a rotary movement of the first shaft 110 is transmitted into the locking device 1000 by the first shaft 110 causing a rotation of a handle receiving portion arranged inside the locking device 1000 in connection with the through hole 1004 as is well known within the art.
  • a rotary movement of the second shaft 120 is transmitted into the locking device 1000 by being coupled inside the adapter 100 to the first shaft 110, as will be discussed in detail below with reference to Fig. 2a-2f.
  • the adapter 100 is mounted on a second side B of a locking device 1000 and when the locking device 1000 is mounted in a door this means that the adapter 100 is on a second side of the door.
  • the locking device 1000 also has a first side A that is on a first side of the door when the locking device 1000 is mounted in the door.
  • a second side B of the locking device thus corresponds to the second side of the door and that this is the side on which the adapter 100 is mounted when in use.
  • the first side A of the locking device corresponds to the first side of the door.
  • the locking device should have a first bolt 1001 that is operated by a first bolt mechanism 1003 that is accessed by insertion of a shaft into a through hole 1004 in the locking device 1000.
  • a second bolt 1002 operable by a second bolt mechanism 1005 that may be accessible by a cylinder 1006 or in any other suitable way.
