Abstract
Abstract Belt clip assembly for use with a portable electronic apparatus includes a mounting bracket used to join a belt clip and a housing member. A mounting bracket is inserted through a pair of slots in a housing member and holds a belt clip in place by means of a pivot pin inserted through apertures in the mounting bracket and the belt clip. A pair of shear cuts adjacent the apertures in the mounting bracket allow the pivot pin to pull through the shear cuts in the event excess forces are applied to the belt clip, thereby destroying the mounting bracket. In this manner an inexpensive mounting bracket is sacrificed to avoid damage to the housing and the belt clip.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
A mounting clip assembly having a controlled mode of failure, comprising: a housing member including an inner surface and an outer surface; a mounting clip; a body member adjacent said inner surface of said housing member; a pair of tabs attached to said body member and projecting substantially perpendicular therefrom, each of said tabs including an outer edge and an aperature, said tabs projecting through slots in said housing member from said inner surface to said outer surface; pivot means attached to said mounting clip, for pivotably attaching said mounting clip to said body member; and said tabs include controlled failure means for allowing said mounting clip and said housing member to separate upon application of a predetermined force between said housing member and said clip thereby minimizing damage to said housing member and said mounting clip.
Claim 2
Dependent Claim
137 words
A mounting clip assembly having a controlled mode of failure, comprising: a housing member including an inner surface and an outer surface; a mounting clip; a body member adjacent said inner surface of said housing member; a pair of tabs attached to said body member and projecting substantially perpendicular therefrom, each of said tabs including an outer edge and an aperature, said tabs projecting through slots in said housing member from said inner surface to said outer surface; pivot means attached to said mounting clip, for pivotably attaching said mounting clip to said body member; and said tabs include controlled failure means for allowing said mounting clip and said housing member to separate upon application of a predetermined force between said housing member and said clip thereby minimizing damage to said housing member and said mounting clip.
Claim 3
Dependent Claim
47 words
The mounting clip assembly of claim 1, wherein said controlled failure means includes a slot in each of said tabs extending from said aperture to said outer edge of said tabs, whereby, said slot opens up to release said pivot means upon application of said predetermined force.
Claim 4
Dependent Claim
14 words
The mounting clip assembly of claim 2, wherein said slot is a shear cut.
Claim 5
Dependent Claim
36 words
The mounting clip assembly of claim 1, wherein said mounting clip is a belt clip and further including a spring positioned between said belt clip and said housing member for normally urging said belt clip closed.
Claim 6
Dependent Claim
41 words
The mounting clip assembly of claim 1, wherein said pivot means includes a pivot pin having two ends and having a threaded portion, and wherein said mounting clip has a passage with a threaded portion adapted to accept said pivot pin.
Claim 7
Dependent Claim
32 words
The mounting clip assembly of claim 5, wherein said pivot pin further includes a screw head at one of said ends and wherein said threaded portion is located adjacent said screw head.
Claim 8
Dependent Claim
161 words
A mounting clip assembly having a controlled mode of failure, comprising: a housing member having an inner and an outer surface and a pair of slots extending from said inner to said outer surface; a mounting clip; a sacrifical mounting bracket including a body member adjacent said inner surface of said housing member, and a pair of tabs attached to said body member and projecting substantially perpendicular therefrom, each of said tabs including an outer edge and an aperture with a shear cut connecting said outer edge and said aperture, said tabs positioned through said slots in said housing member and extending outward from said outer surface; and a pivot pin, attached to said mounting clip and passing through said apertures, for allowing said mounting clip to be pivotably attached to said housing; whereby, upon application of a predetermined force between said mounting clip and said housing member the shear line opens up to allow said pivot pin to pass through.
Claim 9
Dependent Claim
161 words
A mounting clip assembly having a controlled mode of failure, comprising: a housing member having an inner and an outer surface and a pair of slots extending from said inner to said outer surface; a mounting clip; a sacrifical mounting bracket including a body member adjacent said inner surface of said housing member, and a pair of tabs attached to said body member and projecting substantially perpendicular therefrom, each of said tabs including an outer edge and an aperture with a shear cut connecting said outer edge and said aperture, said tabs positioned through said slots in said housing member and extending outward from said outer surface; and a pivot pin, attached to said mounting clip and passing through said apertures, for allowing said mounting clip to be pivotably attached to said housing; whereby, upon application of a predetermined force between said mounting clip and said housing member the shear line opens up to allow said pivot pin to pass through.
