A telephone subset with a desk and wall mount capability employs an east-to-west oriented handset. The subset base has a bearing at a first axis on which the subset housing pivots. The base has slots for the tabs of a bracket to engage and hold the subset in the desk or wall positions. The housing provides a cylindrical well in which a spring loaded pin is mounted, and also provides surfaces on which the subset handset cradle, which houses the hookswitch, rests in the desk and wall configurations. To prevent the bracket from translating, the spring loaded pin engages a hole in the bracket. As the pin is depressed, it disengages the hole and allows the smaller diameter section of the pin to enter the slot so the bracket can translate. The bracket provides an axle on which the cradle mounts, forming a pivot at a second axis, for pivoting from a desk position to a wall position. |

DETAILED DESCRIPTION A telephone subset embodying the invention has a desk and wall mount capability and employs an east-to-west oriented handset. The subset base has a bearing at a first axis on which the subset housing pivots. The base has slots for the tabs of a bracket to engage and hold the subset in the desk or wall positions. The housing provides a cylindrical well in which a spring loaded pin is mounted, and also provides surfaces on which the subset handset cradle, which houses the hookswitch, rests in the desk and wall configurations. To prevent the bracket from translating, the spring loaded pin engages a hole in the bracket. As the pin is depressed, it disengages the hole and allows the smaller diameter section of the pin to enter the slot so the bracket can translate. The bracket provides an axle on which the cradle mounts, forming a pivot at a second axis, for pivoting from a desk position to a wall position. The invention provides an east-to-west handset position for both desk and wall configurations, which provides different styling opportunities, as shown in FIGS. 3 and 4. No additional parts are required with the invention for the user to purchase or store, and no tools are required to convert from desk to wall mount configuration. The user of the invention can easily and quickly convert from desk-to-wall or wall-to-desk configurations as the user's needs change.
