A doorknob assemblage comprises a rose plate (2), a hub section (3), a torsion spring (5), a locking device (6), and a dogging component (4). The dogging component is intended to co-act with the hub section (3) on one side of the rose (2) and is provided with an axially extending abutment member (4a) which passes through a slot (2c) in the rose in a manner to co-act supportingly with the spring on the other side of the rose. The two ends of the slot determine respective terminal positions of the doorknob or like latch release device. The doorknob assemblage is fitted onto a spindle or pin (11) of square cross-section which extends from a lock housing (10). The hub section (3) and the dogging component (4) may optionally comprise a single piece structure. |
