A handle support mechanism is designed for attachment to a door lock, preferably the exterior of a mortise lock, that has two handles driven back to an initial position with a common return spring after either handle is used. The support mechanism prevents the unused handle from drooping or rotating when the common return spring is compressed as the opposite handle is turned. The support mechanism includes first and second friction discs trapped between the exterior of the mortise lock and the legs of a U-shaped spring bracket. The spring bracket applies an inward spring pressure to prevent a friction disc and its corresponding handle from turning when the other handle is in use. The handle support mechanism improves visual appearance and is particularly suitable for retrofit installations, lever handle designs and mortise locks with independent switch sensors on the two handles that notify a monitoring system as to which handle was turned to open a monitored door.

The unit according to claim 1, wherein the batteries are rechargeable. 6. The unit according to claim 1, wherein the seat consists of an annular cylindrical appendage projecting from a riser, projecting in turn orthogonally from an end of the electronic control unit housing, said housing having a generally flattened rectangular shape. 7. An integrated bicycle control and power unit comprising: a housing for an electronic control unit; a battery holder that includes a cylindrical end portion having at least one ring of electrical conductive material forming an external electrical contact for connection with a battery contained in the holder; a circular seat attached to the housing, having at least one internal electrical contact that includes an elastically biased contact pin for connection with the electronic control unit, which receives the cylindrical end portion to quickly couple the holder to the housing and provide an electrical connection between the internal and external contacts. 8. The unit of claim 7 wherein the ring has an external surface defining a circumferential groove for receiving and axially retaining the contact pin.
