Abstract

A belt clip for attaching a device to a user includes a back plate having first and second wing portions which include flanges for engaging with the exterior surface of an electronic device. The first and second wing portions are coupled together by an integrated biasing portion that allows the first and second wing portions to be forced together when the flanges are gripping the electronic device and apart when it is desired to remove the electronic device from the belt clip. The wing portions each include integrally formed cam members that engage with a cam hole formed in a clip member. As the clip member is rotated relative to the back plate, the cam members and thus the wing portions are brought together to grasp the electronic device. The clip member is then retained relative to the back plate with a locking feature.

7. The belt clip of claim 6, wherein said right and left wing members depend from one another by said biasing member, said biasing member forming an arched-shaped portion defining a round aperture between said right and left wing portions.

8. The belt clip of claim 2, wherein said right wing member defines a first transversely extending recess along a portion of an inner edge thereof on a first side of the back member, and said left wing member defines a second transversely extending recess along an inner edge thereof on a second side of the back member, said first and second transversely extending recesses configured to overlap one another when the right wing member is forced toward said left wing member.

9. The belt clip of claim 8, further including a laterally extending post extending from said right wing member for engaging with a top surface of said left wing member, said post and said overlapping recesses preventing relative movement of said right and left wing members in a direction substantially perpendicular to a plane defined by said top surface.

10. The belt clip of claim 2, further including a locking member coupled to said right wing member for engaging with said clip member when said clip member is in a closed position.

11. The belt clip of claim 10, wherein said locking member comprises a cantilevered member integrally formed with said right wing member and having a raised locking portion integrally formed therewith, said raised locking portion configured to engage with said clip member, and said cantilevered member being flexible for selective disengagement of said raised locking portion from said clip member when pressed.

12. The belt clip of claim 11, wherein said clip member defines a recess in a side facing said cantilevered member for receiving said raised locking portion when said clip member is rotated to a closed position relative to said back member.

13. The belt clip of claim 1, wherein each of said cam members further include a cam stop for engaging with cam stop abutments on said clip member to prevent over rotation of said clip member relative to said cam members.

14. The belt clip of claim 13, wherein said cam stop members and said cam stop abutments allow said clip member to rotate approximately ninety degrees relative to said cam members between an open position and a closed position.

15. The belt clip of claim 14, wherein said gripping members are closer together when said clip member is in a closed position and further apart when said clip member is in an open position.

16. The belt clip of claim 15, wherein said biasing member forces said cam members against said cam hole.

17. The belt clip of claim 13, wherein said clip member defines first and second open position cam stop abutments for abutting against said cam stops and preventing over rotation of said clip member in a first direction and first and second closed position cam stop abutments for abutting against said cam stops and preventing over rotation of said clip member in second direction.

18. The belt clip of claim 17, wherein said clip member comprises an integrally formed cam portion defining said cam hole and including said cam abutment surfaces and a belt loop portion for receiving and holding an article of clothing of a user.

19. A belt clip for securing a device to a user, comprising:

a clamping member having integrally formed first and second wing portions interconnected by an arch-shaped portion;

a first grasping flange integrally formed with said first wing portion on a first side thereof and a second grasping flange integrally formed with said second wing portion;
