Abstract
A hinge assembly (2800) for a wireless communication device (100) having a body (104), and a cover (102) including a barrel (216) integrally formed thereon. The hinge assembly (2800) includes a follower (2802), a cam (2804) coupled to the follower (2802) and a spring (2806) coupled to the cam (2804) and coiled around a segment of the follower (2802). The hinge components can be fully assembled and self contained apart from manufacture of the wireless communication device (100).
Claims14
A hinge assembly comprising:
- a follower having an integrally formed connector, a body, at least one tab and an elongated shaft, wherein the shaft comprises a solid portion and a hollow portion defining a plurality of spring retaining prongs;
- a cam rotatably and longitudinally slidably coupled to the shaft of the follower and comprising a cam surface cooperating with the at least one tab, and at least one externally projecting rib;
- and
- a spring coupled on one end to the cam and coiled around the elongated shaft of the follower between the cam and the spring retaining prongs.
In a wireless communication device having a body and a cover, a hinge assembly comprising:
- a follower having an integrally formed connector, a body, at least one tab and an elongated shaft, wherein the shaft comprises a solid portion and a hollow portion defining a plurality of spring retaining prongs;
- a cam having a flat ring surface and a surface shaped with a profile having peaks and valleys cooperating with the at least one tab, the cam rotatably and longitudinally slidably coupled to the shaft of the follower and having at least one externally projecting rib;
- and
- a spring coupled on one end to the cam and coiled around the elongated shaft of the follower between the cam and the spring retaining prongs.
A radiotelephone including a body, a cover and a hinge assembly coupled to the body and cover for joining the body and cover, the hinge assembly comprising:
- a follower having an integrally formed connector, a body, at least one tab and an elongated shaft, wherein the shaft comprises a solid portion and a hollow portion defining a plurality of spring retaining prongs;
- a cam having a flat ring surface, a surface shaped with a profile having peaks and valleys, for cooperating with the at least one tab, and having at least one externally projecting rib the cam rotatably and longitudinally slidably coupled to the shaft of the follower;
- and
- a spring coupled on one end to the cam and coiled around the elongated shaft of the follower between the cam and the plurality of spring retaining prongs.
A hinge assembly comprising:
- a follower having a connector, a body, at least one tab and an elongated shaft, wherein the shaft comprises a solid portion and a hollow portion defining a plurality of spring retaining prongs each forming a lip at an end of the prong:
- a cam rotatably and slidably coupled to the follower for cooperating with the at least one tab and having a radially extending rib;
- and
- a spring coupled on one end to the cam and coiled around a segment of the follower between the cam and the lip.
