ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to improvements to housings for telephone sets. More particularly, the invention relates to an improved reversible base which can be easily removed and reversed for selection of desk or wall mounting of a telephone set.
BACKGROUND OF THE INVENTION
In order to provide greater versatility for a user, it is advantageous to design a telephone set with a base which can be removed and reversed in order to adapt the set for desk-mounting or wall-mounting, at the option of the user. Typical reversible bases of the prior art require the customer to release one or more snaps for removal and then to reapply the snaps for reinstallation. The need to release and reapply the snaps constitutes an inconvenience for the user which it would be desirable to avoid.
There exists, therefore a need in the art for a reversible telephone base in which the removal and reinstallation can be accomplished with a minimum of difficulty, without a need to release or reapply fasteners.
SUMMARY OF THE INVENTION
A telephone set according to the present invention includes a reversible base having alignment tabs for insertion into a pair of matching slots on a housing. The housing includes first and second pairs of matching slots. The pairs of matching slots have opposite orientations to one another. The first pair of matching slots is adapted for installation of the reversible base in a desk mounting orientation. The second pair of matching slots is adapted for installation of the reversible base in a wall mounting orientation. The reversible base is preferably provided with arrows indicating directions of motion for insertion and removal. When the reversible base is oriented to a pair of slots and pushed in the direction indicated for installation, a positive lock occurs. The locking action is provided by pushing each tab over an internal ramp and over a molded protrusion. Removal of the base is accomplished by sliding the base in the opposite direction and removing the tabs from the slots.
A more complete understanding of the present invention, as well as further features and advantages of the invention, will be apparent from the following Detailed Description and the accompanying drawings.
