Pivot hinge and pivotal door leaf

A pivot hinge having a pivot pin member for pivotally connecting a pivotal door leaf with a structural element, the door leaf having an upper edge, lower edge, an inner side edge, and an outer side edge, and the pivot pin member defining a vertical pivot axis for the door leaf,

• wherein the pivot pin member has a cam, the pivot hinge comprising a first cam follower on a first side of the pivot pin member and a second cam follower on a second side of the pivot pin member opposite the first side, the first and second cam followers both being movable in a radial direction relative to the cam,
• wherein the pivot hinge further comprises a casing configured to be mounted to either the door leaf or the structural element, the pivot pin member being configured to be fixed to the other of the door leaf or the structural element,
• wherein a slidable reciprocating member is arranged within the casing and is movably mounted therein, wherein the slidable reciprocating member has a first end part at the first side of the pivot pin member and has a second end part at the second side of the pivot pin member, wherein the first and second end parts are rigidly connected to one another, wherein the first end part is coupled with the first cam follower,
• wherein the cam comprises at least one pair of recesses, each recess configured to receive a respective one of the first and second cam followers, wherein the pair of recesses is provided such that both first and second cam followers are simultaneously retained in the respective recess to form at least one holding position for the door leaf,
• wherein a spring arrangement is arranged between the second cam follower and the second end part and urges both first and second cam followers against the cam as the force exerted by the spring arrangement on the second end part is transferred by the rigid connection to the first end part of the slidable reciprocating member, the first and second cam followers being urged into the respective recess by the spring arrangement arranged between the second cam follower and the second end part to provide a holding moment to retain the door leaf in said holding position for the door leaf.
