Abstract

A belt clip assembly clamps a device (30) onto thin material. The device has a backcover (31) which includes a first set of ears (32) with a first set of pin holes. The belt clip assembly comprises a belt clip (44), a pin (130), and a spring (100). The belt clip (44) has a second set of ears (24,26) with a second set of pin holes (20,22); the pin (130) passes through the first set of pin holes and the second set of pin holes (20,22) for establishing an axis of rotation (56); and the spring (100) is formed to apply force to maintain the belt clip (44) in a closed position against the back cover (31). The spring (100) has a retaining ring (120) formed integrally therewith. The retaining ring (120) couples to the pin (130) for retaining the pin (130) within the first and second set of pin holes (20,22).

Claims

1. A belt clip assembly for clamping a device onto thin material, the device having a backcover including a first set of ears with a first set of pin holes therein, the belt clip assembly comprising:

a belt clip having a second set of ears with a second set of pin holes therein;

a pin for establishing an axis of rotation, the pin passing through said first set of pin holes and said second set of pin holes; and

a spring formed to apply force to maintain said belt clip in a closed position against said back cover, said spring having a retaining ring formed integrally therewith, the retaining ring coupling to said pin for retaining said pin within said first and second set of pin holes.

2. The belt clip assembly of claim 1 wherein the spring comprises:

a first portion having a first end for connecting to the backcover and for exerting force thereagainst and a second end located opposite from said first end;

a second portion having a first end for connecting to the belt clip and for exerting force thereagainst and a second end located opposite from said first end, wherein said second end of said first portion is coupled to said second end of said second portion, of said second portion, and wherein said retaining ring is coupled between said first portion and said second portion.

3. The belt clip assembly of claim 2 wherein said retaining ring is formed to couple said first portion to said second portion at a fractional portion of the distance between said first end and said second end of said first and second portions.

4. The belt clip assembly of claim 3 wherein said first portion and said second portion respectively have a first side and a second side running opposite thereto along the length of said first and second portions, and wherein said retaining ring is formed to couple said first side of said first portion to said first side of said second portion.

5. The belt clip assembly of claim 3 wherein said first portion and said second portion respectively have a first side and a second side running opposite thereto along the length of said first and second portions, and wherein said retaining ring comprises:

a first coupling ring formed to couple said first side of said first portion to said first side of said second portion; and

a second coupling ring formed to couple said second side of said first portion to said second side of said second portion.

6. The belt clip assembly of claim 5 wherein the pin has a first pin retaining groove and a second pin retaining groove formed therein, and wherein the first coupling ring of said spring couples with said pin so that a portion of said first coupling ring fits within said first pin retaining groove, and wherein the second coupling ring of said spring couples with said pin so that a portion of said second coupling ring fits within said second pin retaining groove.

7. The belt clip assembly of claim 2 wherein the belt clip has a spring retaining groove formed therein and wherein the second portion of said spring has a protrusion formed at said first end for fitting into said spring retaining groove.

8. The belt clip assembly of claim 2 wherein the back cover has a spring retaining groove formed therein and wherein the first portion of said spring has a protrusion formed at said first end for fitting into said spring retaining groove.

9. The belt clip assembly of claim 1 wherein the pin has a pin retaining groove formed therein and wherein the retaining ring of said spring couples with said pin so that a portion of said retaining ring fits within said pin retaining groove.

10. A selective call receiver with belt clip assembly comprising:

selective call receiver circuitry for receiving and decoding selective call messages;

a housing for housing the selective call receiver circuitry, the housing having a back cover, the back cover having a set of ears formed thereon, the set of ears including a first set of pin holes therein;

a belt clip having a set of ears formed thereon, the set of belt clip ears including a second set of pin holes therein;

a pin for establishing an axis of rotation, the pin passing through said first set of pin holes and said second set of pin holes; and

a spring formed to apply force to maintain said belt clip in a closed position against said back cover, said spring having a retaining ring formed integrally therewith, the retaining ring coupling to said pin for retaining said pin within said first and second set of pin holes.
