Further, the coupling recess 45 is elongated in a circumferential direction of the first actuation member 41.
  • the coupling member 60 is in a position where it does not couple with the actuation mechanism coupling portion; rather, it is rotated so that a curved inner side faces toward the first rotational axis R1.
  • the first actuation member 41 can be rotate without the coupling member 60 preventing it from doing so.
  • the inner handle 20 may be rotated about the second rotational axis R2 from the first position 20P1 to a second position 20P2 as indicated by the direction of the arrow in Fig. 4 .
  • This rotation of the inner handle 20 consequently causes the second actuation member 42 to rotatably interact with the cam unit via the second set of cam unit cogs 34, thereby causing the cam unit 30 to rotate about the cam unit axis C from the locking position 30P1 to an open position.
  • the coupling member 60 since the coupling member 60 is not coupled with the first actuation member 41, the outer handle 10 remains in the first position 10P1 despite the first actuation member 41 being forced to rotate due to cog interaction with the cam unit 30.
  • the coupling member 60 resides outside the actuation mechanism coupling portion 46.
  • FIG. 10 the coupling member 60 is rotated away from a coupling position so that the curved inner side faces the first and second rotational axis R1, R2.
  • Fig. 11 the coupling member 60 is rotated about the axis X so that it is in a position to couple with the actuation mechanism coupling portion 46.
  • the coupling member 60 slides along the coupling recess 45 until it abuts the actuation mechanism coupling portion 46, see Fig. 12 .
  • the outer handle 10 causes the first actuation member 41 to rotate about the first rotational axis R1, thereby causing the cam unit 30 to rotate away from the locking position 30P1 toward the open position 30P2.
  • the coupling member 60 is configured to reside in a housing recess 72 when the outer handle lock 50 is in a locking position. By this, operation of the outer handle 10 is prevented as the coupling member 60 rotationally fixes the outer handle 10 with the housing 70.
  • the door handle arrangement 1 may comprise attachment means for attaching the housing 70 to a door 100, and the cam unit receiver 75 to a door frame 110 as shown in Fig. 14 .
  • the handle arrangement 1 When the handle arrangement 1 is in a closed position, i.e. the cam unit 30 couples with the cam unit receiver 75, thereby holding the door 100 hinged to the door frame 110 by means of the hinges 120 in a shut state.
  • the door 100 may be correspondingly opened.
  • the door 100 may be opened using the inner door handle 20, thereby ensuring that the door handle arrangement 1 only provides locking functionality in one opening direction.
  • Figs. 15 and 16 illustrate one embodiment of the present invention.
  • the first actuation member 41 and the second actuation member 42 of the actuation mechanism 40 engages with only a single set of cam unit cogs 33 of the cam unit 30.
  • the cogs 43, 44 of the first and second actuation member 41, 42 may be identical in shape. They may have a different thickness along the rotational axis.
  • the coupling member 60 and the actuation mechanism coupling portion are each provided with an inclined interface with respect to the rotational axis of the coupling member by which they interact when the coupling member 60 rotates about the cylinder lock axis X into a coupling position.
  • the inclined interface of the actuation mechanism coupling portion is provided in a coupling recess 45 configured to receive the coupling member 60.
  • the door handle arrangement 1 comprises at least one coupling member blocker 65.
  • the purpose of the coupling member blocker 65 is to provide a two-step unlocking process of the door handle arrangement 1 and the door 100 to which the door handle arrangement 1 is arranged.
  • the first step involves unlocking the outer handle lock 50 to an unlocking state, which moves the coupling member into a position for coupling with the actuation mechanism 40.
  • the second step includes moving the coupling member 60, by means of the outer handle 10, to operate the actuation mechanism 40 such that the cam unit 30 is moved towards the open position.
  • the coupling member 60, and thereby also the outer handle 10 is only moveable a part of the distance towards the open position 10P2.
  • the coupling member blocker 65 prevents the coupling member 60 from further rotation at an intermediate position.
  • the cam unit 30 has moved from the locking position 30P1 towards the open position 30P2 but stopped at an intermediate position.
  • the cam unit 30 may still be engage with the cam unit receiver 75 such that full opening of the door 100 relative to the door frame 110 may be prevented.
  • the cam unit 30 may be in a position where the compression between the door 100 and the door frame 110 has decreased.
  • a sliding of the coupling member blocker 65 may be provided a distance d from a retracted position to an extended position in a sliding direction L1 so as remove a blocking edge 653 of the coupling member blocker 65 which is configured to block the coupling member 60 from moving the full distance towards the open position 30P2 of the cam unit 30.
  • the coupling member blocker 65 is in the retracted position, the coupling member 60 is only enabled to move a certain distance along with the actuation mechanism 40 before being blocked by the blocking edge 653 of the coupling member blocker 65.
  • the outer handle 10 when the outer handle 10 is operated to open the door 100 and move the cam unit 30 to the open position 30P2, the outer handle 10 is rotated towards the open position 10P2, thereby moving the coupling member 60 to act on the actuation mechanism 40. At an intermediate position, the coupling member 60 is prevented from further movement by the coupling member blocker 65, leaving the cam unit 30 at an intermediate position.
  • the coupling member blocker 65 is moved to the extended position such that the coupling member 60 is enabled to move further.
  • the outer handle 10, the coupling member 60 and the cam unit 30 can thereby move to the open position 30P2 of the cam unit 30 to open the door 100.
  • the coupling member blocker 65 may comprise a coupling member blocker grip 651 for facilitated gripping of the coupling member blocker 65 when moving the coupling member blocker between the retracted position and the extended position.
  • the coupling member blocker 65 may provide a housing part 652 sized and shaped so as to conform with the housing 70.
  • the coupling member blocker 65 may be biased toward the retracted position. By this, the coupling member blocker 65 may return to the retracted position from an extended position.
  • the coupling member blocker 65 may be biased toward the retracted position by means of a coupling member blocker spring 654, see Fig. 18 .
  • the coupling member blocker spring 654 may be arranged so that one longitudinal end abuts the coupling member blocker spring 654 and an opposite longitudinal end abuts an interior part of the housing 70, for instance an inside wall of the housing 70.
  • the coupling member blocker 65 may provide a spring recess for housing at least a portion of the coupling portion blocker spring 654 so as to keep it aligned accordingly.
  • the housing 70 may be sized and shaped so as to enable the coupling member blocker 65 to linearly move in a controlled manner.
  • the door handle arrangement 1 may provide fail-safe closing functionality as shown in Figs. 18 - 22 .
  • This is enabled by means of a pre-biased slider unit 74 configured to move relative the housing 70 along a second sliding axis L2 under influence of one or more slider unit springs 744 towards an extended position at which the slider unit 74 extends out of the housing 70.
  • the slider unit 74 is configured so that it, when the cam unit 30 is in a locking position, extends into the cam unit receiver 75.
  • the slider unit 74 may in the extended position abut an interior of the cam unit receiver 75 through the opening 76.
  • the door handle arrangement 1 When the cam unit 30 is moved from the locking position to the open position, the door handle arrangement 1 is configured so that the cam unit coupling member 31 engages with the slider unit 74, thereby causing the slider unit 74 to move toward a retracted position, in which position the slider unit 74 is retracted at least partly into the housing 70.
  • the cam unit 30 moves to the fully open position 30P2
  • the slider unit 74 is fully retracted out of the cam unit receiver opening 76, thereby allowing the cam unit receiver 75 to disengage from the rest of the door handle arrangement 1, which consequently allows a door 100 to be opened.
  • the one or more slider unit springs 744 may push the slider unit 74 into the extended position, thereby preventing accidental closing of the door 100 in the door frame 110. Further, if the door is closed, the slider unit 74 may facilitate the cam unit 30 to move from the fully open position 30P2 towards the locking position 30P1.
  • the door handle arrangement 1 comprises an inner housing member 73 and the slider unit 74 is configured to engage with the inner housing member 73 as shown in Figs. 21 - 22 .
  • the inner housing member 73 is sized and shaped so as to define two slider unit recesses 731 by which corresponding portions of the slider unit 74 interacts in a sliding manner.
  • the sliding unit 74 comprises a set of first slider unit stops 741 for abutting an interior of the cam unit receiver 75 in the fully extended position.
  • the sliding unit 74 comprises a set of second slider unit stops 742 for abutting with the inner housing member 73 in the fully retracted position.
  • the door handle arrangement 1 further comprises a set of slider unit springs 744 arranged to extend along a slider unit recess 731 and a slider unit spring recess 745, and further configured to bias the slider unit 74 into the extended position.
  • the sliding unit 74 comprises a cam unit axle opening 746 through which an axle of the cam unit 30 axle extends, which rotatably couples the cam unit 30 to the housing 70.
  • the opening 746 is elongated so as to enable the sliding 74 unit to slide along the second sliding axis L2.
  • the sliding unit 74 comprises a set of cam unit recesses sized and shape so as to allow the cam unit coupling member 31 to be rotated there into and also securely receive the cam unit 30 in the fully open position 30P2.
