Definitions

  • the present disclosure generally relates to lock devices.
  • a blocker for a lock device an arrangement for a lock device, and a lock device, are provided.
  • a lock device in a door leaf may comprise a manually operated handle and a bolt movable by the handle between an extended position and a retracted position. In the extended position, the bolt may engage a strike in a frame such that the door leaf cannot be opened. In the retracted position, the bolt does not engage the strike and the door leaf can be opened.
  • Such lock device may comprise a blocking member movable between a blocked position and an unblocked position. In the blocked position, the blocking member blocks movements of the handle such that the handle cannot be rotated. In the unblocked position, the handle can be rotated to retract the bolt.
  • One object of the invention is to provide an improved blocker for a lock device.
  • a further object of the invention is to provide an improved arrangement for a lock device.
  • a further object of the invention is to provide an improved lock device.
  • the blocker according to appended claim i the arrangement according to appended claim io and the lock device according to appended claim 14.
  • the invention is based on the realization that by providing a rotatable blocking member driven between a blocking position and an unblocking position by an actuator via a resilient device, the blocker can be made very durable with a low-complex design, and can operate with extremely low power consumption.
  • a blocker for a lock device comprising a blocking member rotatable about a blocker axis between a blocking position and an unblocking position; a resilient device movable between a blocking forcing state where the resilient device forces the blocking member towards the blocking position, and an unblocking forcing state in which the resilient device forces the blocking member towards the unblocking position; and an actuator arranged to move the resilient device between the blocking forcing state and the unblocking forcing state.
  • the actuator can move the resilient device to the unblocking forcing state against the resiliency of the resilient device if the blocking member is blocked from being moved from the blocking position to the unblocking position. The actuator may then be stopped. Once the blocking member is unblocked, the resilient device will force the blocking member to move to the unblocking position.
  • the blocker thus provides a mechanical memory enabling the actuator to only be driven for short periods of time. Thus, energy consumption is reduced.
  • the blocking member Due to the blocking member being rotatable about the blocker axis, the blocking member can have a low mass and the blocking member can be moved a relatively short angular distance between the blocking position and the unblocking position. These effects enable a low energy consumption and more cost-efficient design.
  • the blocker can perform a very reliable selective blocking and unblocking of an external member, such as a rotatable member, and has a low-complex yet durable design. For example, if a handle of the lock device is depressed such that the blocking member becomes blocked and the actuator is commanded to move the blocking member by moving the resilient device from the blocking forcing state to the unblocking forcing state, the energy from the actuator will be temporarily stored in the resilient device as potential energy and will be released to drive the blocking member when the handle is released.
  • the solution enables a low power consumption and requires very few parts.
  • the blocker efficiently solves the problem that the blocking member can be blocked by manually pressing the handle when the actuator is actuated.
  • the blocking member may be rigid.
  • the blocking member may be a blocking lever.
  • the blocking member may rotate less than 45 degrees, such as 30 degrees, between the blocking position and the unblocking position.
  • the blocking member may comprise a blocking surface for being contacted by the rotatable member.
  • the resilient device may be configured to be resiliently deformed when the resilient device is moved from the blocking forcing state to the unblocking forcing state if the blocking member is held in the blocking position.
  • the blocking member may be elongated along a longitudinal axis substantially perpendicular to, or perpendicular to, the blocker axis.
  • the blocking surface may be substantially perpendicular to, or perpendicular to, the longitudinal axis.
  • the resilient device may comprise a spring.
  • the resilient device may comprise one or more magnets to force the blocking member with magnetic force.
  • the spring maybe a torsion spring arranged around the blocker axis.
  • the spring may for example be wound around a shaft concentric with the blocker axis.
  • the spring may comprise a driven leg for being moved by the actuator to thereby move the resilient device between the blocking forcing state and the unblocking forcing state.
  • the driven leg may extend in a plane substantially parallel with, or parallel with, the blocker axis in each of the blocking forcing state and the unblocking forcing state.
  • the actuator may comprise a screw having a thread.
  • the screw may be a worm.
  • the screw may be rotatable about a screw axis.
  • the longitudinal axis may be substantially perpendicular to, or perpendicular to, the screw axis when the blocking member adopts the blocking position.
  • the driven leg maybe arranged to engage the thread during movement of the resilient device between the blocking forcing state and the unblocking forcing state. In this way, the resilient device cooperates with both the screw and the blocking member.
  • the screw may comprise two non-threaded sections.
  • each nonthreaded section may be configured to receive the driven leg and the thread may be arranged between the non-threaded sections.
  • the provision of the non-threaded sections enables the actuator to drive the driven leg without position control. A cheaper actuator can thereby be used.
  • the screw and the resilient device may be configured such that the driven leg is preloaded when positioned in each of the non-threaded sections. When the driven leg is positioned in a first non-threaded section among the non-threaded sections and the screw rotates in a first direction, the driven leg will remain disengaged from the thread.
  • the preload of the resilient device When the screw rotates in a second direction, opposite to the first direction, the preload of the resilient device will cause the driven leg to immediately start engaging the thread. Conversely, when the driven leg is positioned in a second non-threaded section among the nonthreaded sections and the screw rotates the second direction, the driven leg will remain disengaged from the thread. When the screw rotates in the first direction, the preload of the resilient device will cause the driven leg to immediately start engaging the thread.
  • the resilient device may be undeformed in the blocking forcing state when the blocking member adopts the blocking position, and may be undeformed in the unblocking forcing state when the blocking member adopts the unblocking position.
  • the actuator may comprise an electric motor arranged to rotate the screw.
  • an arrangement for a lock device comprising a blocker according to the first aspect and a rotatable member rotatable about a rotatable member axis and arranged to be blocked by the blocker.
  • the rotatable member may be a spindle.
  • the blocking member may be arranged to be clamped between the rotatable member and the blocker axis when the blocking member is in the blocking position. In this way, the blocking member can take forces from the rotatable member without imparting loads on the resilient device or on the actuator.
  • the rotatable member may be capable of contacting and holding the blocking member in the blocking position against the force from the resilient device when the resilient device is in the unblocking forcing state.
  • the rotatable member may comprise an arm.
  • the rotatable member surface may be provided at the arm, such as at a distal end of the arm. By increasing a length of the arm, the forces acting on the blocking member can be reduced. By clamping the blocking member in this way, the blocking member can provide a high blocking force even with a relatively small and weak design.
  • a distance between the rotatable member surface and the rotatable member axis may be longer than a distance between the blocking surface and the blocker axis.
  • the rotatable member surface may be substantially perpendicular to, or perpendicular to, the longitudinal axis in at least one rotational position about the rotatable member axis when the blocking member is in the blocking position.
  • the rotatable member surface may be arranged to be brought into contact with the blocking surface.
