Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A portable knife, comprising: a plurality of elongated plates extending in a longitudinal direction; means for joining the plurality of elongated plates together into a layered assembly in which the individual plates are co-extensive, at least one of said plates including a pair of elongated, parallel legs extending in the longitudinal direction which define a pocket between them open at one end, one of said legs being displaceable transversely to the longitudinal direction; a knife pivotably mounted at one end of the assembly; and a utensile including an elongated portion which is received through the open end of said pocket, longitudinally into said pocket and retained therein, said displaceable leg being displaceable transversely outwardly from the assembly to receive said elongated portion.
Claim 2
Dependent Claim
122 words
A portable knife, comprising: a plurality of elongated plates extending in a longitudinal direction; means for joining the plurality of elongated plates together into a layered assembly in which the individual plates are co-extensive, at least one of said plates including a pair of elongated, parallel legs extending in the longitudinal direction which define a pocket between them open at one end, one of said legs being displaceable transversely to the longitudinal direction; a knife pivotably mounted at one end of the assembly; and a utensile including an elongated portion which is received through the open end of said pocket, longitudinally into said pocket and retained therein, said displaceable leg being displaceable transversely outwardly from the assembly to receive said elongated portion.
Claim 3
Dependent Claim
41 words
The portable knife as defined in claim 1, wherein the transversely displaceable leg includes a projection at the open end which projects into the pocket, and wherein the elongated portion of the utensile includes a groove dimensioned to receive said projection.
Claim 4
Dependent Claim
39 words
The portable knife as defined in claim 2, wherein the transversely displaceable leg further includes a hole adjacent to the projection for receiving the joining means with play to thereby permit the transverse displacement of said transversely displaceable leg.
Claim 5
Dependent Claim
77 words
The portable knife as defined in claim 3, wherein two of said plates include a pair of elongated, parallel legs extending in the longitudinal direction each of which defines a pocket between them open at one end, one of said legs of each plate being displaceable transversely to the longitudinal direction, and wherein two utensiles are provided each with an elongated portion received in a respective one of the pockets, said utensiles comprising a spoon and fork.
Claim 6
Dependent Claim
38 words
The portable knife as defined in claim 4, wherein the plates are provided with holes which are aligned and define a bore in assembly, and wherein the means for joining the plates comprises rivets received within said bores.
Claim 7
Dependent Claim
