Device for turnable and slidable suspension of plates

A device for turnable and slidable suspension of a sheet element, said element being slidably supported by at least one rail and turnable about a pivot axis which is fixed relative to the sheet element, comprising a coupling member supported by said at least one rail and having an elongate groove extending in essentially a same direction as the at least one rail, and a coupling pin non-rotationally arranged on the sheet element so as to coincide with the pivot axis of said element and which is slidable in the groove of the coupling member, the coupling pin and the coupling member being constructed and arranged to engage each other when the sheet element is turned relative to the at least one rail, wherein

• the groove of the coupling member has an inclined, lateral cam surface,
• the coupling member has at least one essentially part-circular recess in the inclined lateral cam surface, the recess having a center axis which is essentially parallel to the pivot axis of the sheet element,
• the coupling pin has a cylindrical surface with a center axis which is essentially parallel to the pivot axis of the sheet element,
• the cylindrical surface of the coupling pin has a beveled portion having a shape which is essentially the same as a cam shape of the lateral cam surface in the groove of the coupling member, and
• the coupling member and the coupling pin being arranged to be displaceable when the coupling pin is turned in such a manner that the inclined lateral surface in the groove and the beveled portion of the coupling pin abut against each other, and to engage each other when the cylindrical surface of the coupling pin, during turning of the sheet element, engages the part-circular recess of the coupling member.
