Claim 1
Independent Claim
230 words
A case for holding and displaying objects such as drill bits, the case comprising: an elongated and upwardly open box; an insert adapted to hold a plurality of the objects and pivotal in the box about an insert axis between a down position wholly contained therein and an up position projecting upward therefrom; a U-shaped link having a pair of legs pivoted on the insert and a straight bight portion extending substantially parallel to the axis, interconnecting the legs, and of a predetermined bight length between the legs; a lid pivotal on the box between a closed position engaging over and closing the box and an open position projecting upward therefrom, the lid being formed with a pivot loop through which the bight portion passes and which has a pair of outer edges spaced axially apart substantially by the bight length, whereby the bight portion cannot move axially relative to the lid, a window at the pivot link having a pair of outer edges spaced apart parallel to the axis by a distance greater than the bight length, and a strut bridging the window parallel to and between the window edges, whereby the bight portion engages against the strut on closing of the lid; and a cover plate having respective snap tabs spaced apart axially by a distance greater than the bight length and engaged snugly against the window edges.

Dependent Claim

A case for holding and displaying objects such as drill bits, the case comprising: an elongated and upwardly open box; an insert adapted to hold a plurality of the objects and pivotal in the box about an insert axis between a down position wholly contained therein and an up position projecting upward therefrom; a U-shaped link having a pair of legs pivoted on the insert and a straight bight portion extending substantially parallel to the axis, interconnecting the legs, and of a predetermined bight length between the legs; a lid pivotal on the box between a closed position engaging over and closing the box and an open position projecting upward therefrom, the lid being formed with a pivot loop through which the bight portion passes and which has a pair of outer edges spaced axially apart substantially by the bight length, whereby the bight portion cannot move axially relative to the lid, a window at the pivot link having a pair of outer edges spaced apart parallel to the axis by a distance greater than the bight length, and a strut bridging the window parallel to and between the window edges, whereby the bight portion engages against the strut on closing of the lid; and a cover plate having respective snap tabs spaced apart axially by a distance greater than the bight length and engaged snugly against the window edges.
Claim 3
Dependent Claim
15 words
The case defined in claim 1 wherein the lid and the strut are generally coplanar.
Claim 4
Dependent Claim
38 words

Claim 8
Dependent Claim
24 words
