Abstract

Abstract A device is disclosed for providing a non-resettable visual indication of a shock above a predetermined value which is sustained by an object carrying the device, comprising a dome-like housing, at least part of which is transparent; a flange means secured to and extending radially outward from the dome-like housing; a plate-like biasing means secured to the dome-like housing, the plate-like biasing means and the interior surface of the top portion of the dome-like housing being spaced apart and defining a chamber therein; and an indicating body within the chamber positioned between the biasing means and the interior surface of the top portion of the housing. Prior to being subjected to a force above the predetermined value, the indicating body is maintained in a first position and when subjected to a force above the predetermined value is irreversibly released to a second position.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 200 words
A device for providing a non-resettable, visual indication of a shock above a predetermined value sustained by an object carrying the device, comprising: a housing means at least part of which is transparent including: a dome-like portion having a central axis, a top portion, at least part of which is transparent, and a peripheral side wall portion; a flange means extending radially outward from said side wall portion; a plate-like biasing means fixedly secured to said housing and extending inwardly from said peripheral side wall portion and substantially perpendicular to said axis, said biasing means and the top portion of said dome-like portion spaced apart and defining a chamber; and an indicating body within said chamber positioned between said biasing means and the top portion of said dome-like portion, said body being normally pressed by said biasing means in a first position in contact with the transparent part of said top portion with a force sufficient to maintain said body in said first position when subjected to a force below said predetermined value but said biasing means irreversibly releasing said body from said first position to a second position spaced therefrom upon being subjected to a shock exceeding said value.
Claim 2
Independent Claim 200 words
A device for providing a non-resettable, visual indication of a shock above a predetermined value sustained by an object carrying the device, comprising: a housing means at least part of which is transparent including: a dome-like portion having a central axis, a top portion, at least part of which is transparent, and a peripheral side wall portion; a flange means extending radially outward from said side wall portion; a plate-like biasing means fixedly secured to said housing and extending inwardly from said peripheral side wall portion and substantially perpendicular to said axis, said biasing means and the top portion of said dome-like portion spaced apart and defining a chamber; and an indicating body within said chamber positioned between said biasing means and the top portion of said dome-like portion, said body being normally pressed by said biasing means in a first position in contact with the transparent part of said top portion with a force sufficient to maintain said body in said first position when subjected to a force below said predetermined value but said biasing means irreversibly releasing said body from said first position to a second position spaced therefrom upon being subjected to a shock exceeding said value.
Claim 3
Dependent Claim 29 words
A device according to claim 1, wherein said indicating body is a ball and said biasing means includes a support column with a cupular support surface for said ball.
Claim 4
Dependent Claim 48 words
A device according to claim 2, wherein said biasing means consists in one piece of an annular plate element, said support column for said ball arranged centrally within said plate element and extending perpendicular to said plate element, and spoke-like arms connecting said plate element to said column.
Claim 5
Dependent Claim 72 words
A device according to claim 3, including a bottom plate fixedly secured and in spaced relationship to said flange means, said bottom plate and said flange means defining an aperture therebetween, and a locking means removeably positioned in said aperture and pressing against the surface of said column opposite the cupular support surface, said locking means preventing movement of said column toward said bottom plate before the device is placed in use.
Claim 6
Dependent Claim 19 words
A device according to claim 4, including a means for hindering reinsertion of said locking means in said aperture.
Claim 7
Dependent Claim 62 words
A package for holding shock indicating devices, said package comprising: a closed receptacle containing a plurality of the devices of claim 1, said indicating devices being placed in contact with one another within said package such that said dome-like portion of one device presses against said biasing means of an adjacent device such that irreversible release of said indicating body is avoided.
Claim 8
Dependent Claim 72 words
A package defining a container for an article subject to shock, said package comprising a wall portion including at least one aperture defined therein and at least one indicating device according to claim 1, said flange means of said at least one indicating device being secured to an interior surfaceof said wall portion of said package and said transparent part of said top portion being viewable through said at least one aperture.
