Electronic device having a cam assembly functioning as a depressible hinge

A housing assembly, comprising:

• a first housing portion having a cavity;
• a second housing portion rotationally coupled to the first housing portion;
• and
• cam assembly means contained by the cavity of the first housing portion, the cam assembly means coupled to the first and second housing portions, the cam assembly means consisting of:
• cam means,
• cam follower means, and
• resiliently biasing means for biasing the cam means and the cam follower means into engagement,
• wherein at least one of the cam means and cam follower means is depressible within the cavity of the first housing portion for permitting assembly with the second housing portion, and wherein one of the cam means and cam follower means is keyed to the cavity.

A housing assembly, comprising:

• a first housing portion having a cavity;
• a second housing portion having a keyed portion coupled to the first housing portion;
• and
• a cam assembly contained by the cavity of the first housing portion, the cam assembly coupled to the first and second housing portions, the cam assembly consisting of:
• a cam,
• a cam follower,
• a spring resiliently biasing the cam and the cam follower into engagement, and
• a cap holding,
• the cam, the cam follower and the spring in place on the first housing portion,
• one of the cam and cam follower has a keyed portion for engaging the keyed portion included in the second housing portion,
• wherein one of the cam and cam follower is keyed to the cavity, and
• at least one of the cam and cam follower is depressible within the cavity of the first housing portion for permitting interlocking assembly of the first and second housing portions, and for rotational coupling at the first and second housing portions.
