Definitions
- the inventive concept described herein generally relates to coupling arrangements, and in particular to a coupling arrangement for selectively engaging and disengaging a first and a second shaft.
- Coupling mechanisms for selectively coupling shafts are known in the art. Such coupling mechanisms may be used to provide access to closed and/or secured areas or rooms via e.g. locks in doors, windows, containers, or the like. Some coupling mechanisms physically prevent e.g. a handle of a door to be turned while in the locked state. These are often possible to force open simply by applying enough force to break the mechanism preventing rotation.
- a coupling arrangement for selectively engaging and disengaging a first and a second shaft extending coaxially along an axis A
- the coupling arrangement comprises: a first coupling member configured to be secured to the first shaft, wherein the first coupling member has a circular cross-sectional shape transverse to the axis A and an outer surface comprising at least one groove; a second coupling member configured to be secured to the second shaft, wherein the second coupling member comprises a sleeve shaped element coaxial with axis A and at least one through hole arranged in the sleeve shaped element radially to the axis A, wherein the first coupling member is configured to be rotatably housed within the sleeve shaped element; a selecting element; and at least one locking element; wherein the coupling arrangement is configured to assume an engaged configuration, in which the selecting element is arranged in an engaged position such that the
- the coupling arrangement according to the inventive concept provides for that the first and second shaft may be disengaged such that no force is transmitted from the first axis to the second axis. Further, the disengaged configuration allows the first shaft and the first coupling member to rotate freely with respect to the second coupling member and the second shaft. Hence, the coupling arrangement is less susceptible to break through attempts or failure by merely applying high torque via the first shaft.
- An outer radius of the first coupling member may correspond to an inner radius of the sleeve shaped element, thus allowing the first coupling member to be rotatably housed within the sleeve shaped element.
- the at least one groove may extend parallel to the axis A.
- the at least one groove may be configured to be in contact with two or more locking elements.
- the first coupling member may comprise one groove corresponding to each locking element comprised in the coupling arrangement, and/or the at least one groove may be extended such that one or more locking elements fit in the at least one groove side by side along the axis A.
- the at least one groove may be open ended, preferably at an end proximal to the second shaft.
- disassembly of the coupling arrangement may be facilitated, e.g. the first coupling member may be moved in a direction parallel to the axis A even if the selecting element is in the engaged position, i.e. even if the locking elements are in contact with the at least one groove.
- the selecting element may comprise at least one magnetic element arranged on the selecting element.
- the coupling arrangement may further comprise a magnetic sensor arrangement configured to determine a position of the selecting element relative the second coupling member based on the at least one magnetic element.
- the magnetic sensor arrangement may be arranged on a circuit board positioned in proximity of the coupling arrangement.
- the at least one groove may be arranged to align with the at least one through hole when the coupling arrangement is in the engaged configuration.
- the at least one locking element may be in contact with the inner surface of the at least one through-hole and with the at least one groove.
- the at least one locking element may be spherically shaped.
- the at least one locking element may withstand high loads e.g. when the coupling arrangement is in the engaged configuration and torque is applied to the first shaft.
- a spherically shaped element may also provide for that forces are evenly distributed over the at least one locking element. Further, a spherically shaped locking element may be easily moved into and out of the at least one groove.
- the at least one groove may comprise inclined side walls configured to bias the at least one locking element to move out of the at least one groove.
- the at least one locking element may easily move out of the at least one groove, assisted by gravity, when the selecting element is in the disengaged position.
- the inclined side walls may create a better force transmission from the first shaft to the second shaft via the first and second coupling member.
- the inclined side walls may be inclined with respect to a radial direction.
- the inclined side walls may be inclined by at least 10 degrees, such as by at least 20 degrees, with respect to the radial direction.
- the inclined side walls may be inclined with respect to a bottom surface of the at least one groove.
- the inclined side walls may be inclined by more than 90 degrees, such as between 100 and 110 degrees with respect to the bottom surface of the at least one groove.
- the coupling arrangement may further comprise a driving unit configured to move the selecting element between the engaged position and the disengaged position.
- the driving unit may be e.g. a step motor, and/or a mechanical
- the selecting element may be configured to rotatably encase an outer surface of the second coupling member about the axis A, wherein the selecting element comprises at least one recess defining a cavity between the selecting element and the outer surface of the second coupling member, wherein the cavity is arranged to at least partly receive the at least one locking element when the selecting element is in the disengaged position.
- the at least one locking element may be at least partly arranged within said cavity when the selecting element is in the disengaged position.
- the at least one locking element may be held at least partly within the at least one through-hole, while not being in contact with the at least one groove, thus allowing the first coupling member to rotate freely about the axis A with respect to the second coupling member.
- the first coupling member, second coupling member, and selecting element may be configured such that when the coupling arrangement is in the engaged configuration, the first and second coupling member may rotate freely with respect to the selecting element.
- the selecting element may be configured to be held in place, e.g. by the driving unit, when the first and/or second coupling member is rotated.
- the range of motion about the axis A may be defined by an extension of the cavity around a circumference of the first coupling member. This will be further discussed in the detailed description of the present disclosure.
- the at least one cavity may extend within a sector of the circular
- the sector may have an angle being equal to or less than 50 degrees, such as equal to or less than 45 degrees.
- the first and second coupling member may be rotated a maximum of e.g. 50 or 45 degrees with respect to the selecting member.
- arrangement may allow e.g. a handle being connected to either of the first and second shaft to be rotated a maximum of e.g. 50 or 45 degrees.
- the selecting element may comprise gear teeth configured to engage with a force feed element of the driving unit.
- the recess may comprise inclined side walls configured to facilitate movement of the at least one locking element into contact with the at least one groove upon rotating the selecting element about the axis A to the engaged position.

- Either of the first and second shaft may be connected to a handle and the other to a locking case.
- a simple coupling arrangement for managing access via a door may be provided.
- a feature described in relation to one aspect may also be incorporated in other aspects, and the advantage of the feature is applicable to all aspects in which it is incorporated.
