Abstract: A telephone handset mounting cradle includes a housing provided along its lower edge with opposed oppositely opening grooves. The bottom of the housing includes a relief. A bracket includes opposed, facing slides for engaging the grooves and a spring clip for engaging the relief to lock the cradle to the bracket. A screw pivotally couples the bracket to a first plate about a first axis. Additional screws pivotally couple the first plate to a second plate about a second axis perpendicular to the first. The second plate includes provisions for fixed mounting to a surface.

Abstract: A combination charging unit and portable, hand-held transceiver which includes a latch mechanism operable to effect an electrical connection between the charging circuit in the charging unit and the rechargeable power supply in the transceiver automatically upon insertion of the transceiver into the charging unit. The latch mechanism causes insertion of plug connectors on the charging unit into mating connectors in the transceiver in a direction which is perpendicular to the axis of insertion of the transceiver into the charging unit. The latch mechanism prevents damage to the plug connectors by exerting a predetermined constant insertion force, independent of the force employed to seat the transceiver into the charging unit, in mating the plug connectors. The latch mechanism includes a release lever which provides a mechanical advantage to the operator during the initial portion of its release movement thus compensating for the gripping effect of the plugs with their mating connectors.

Abstract: Improved ringer signal circuitry in a telephone handset modifies the leading edge of the ringer signal envelope causing ringer volume to gradually increase, over a period of time, to its maximum value.
