Abstract
Abstract A hinge adjustment tool for use on self-closing hinges for kitchen cabinets has the form of a bar of hot rolled steel in which end portions of the bar are displaced out of the plane of the intermediate portion of the bar in opposite directions at an angle of about 45° by a cold bending operation, the end portions each having a slot opening to one of its longitudinal edges and facing in opposite directions, and with the end portions of the tool being hardened by heat treatment.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
89 words
A hinge adjustment tool comprising: a hot rolled steel bar having heat treatment hardened, opposite end portions projecting out of the plane of the intermediate portion in opposite directions and at an angle between 45° and 75°, said end portions being displaced to the angularly projecting positions by a cold bending operation, each end portion having a slot in one of its longitudinal edges, the slot in one end portion being open to one edge and the slot in the other end portion being open to the other edge.
Claim 2
Dependent Claim
89 words
A hinge adjustment tool comprising: a hot rolled steel bar having heat treatment hardened, opposite end portions projecting out of the plane of the intermediate portion in opposite directions and at an angle between 45° and 75°, said end portions being displaced to the angularly projecting positions by a cold bending operation, each end portion having a slot in one of its longitudinal edges, the slot in one end portion being open to one edge and the slot in the other end portion being open to the other edge.
Claim 3
Dependent Claim
139 words
A hinge adjustment tool comprising: a bar of hot rolled steel having at each end an end portion projecting out of the plane of the intermediate section at an acute angle sufficiently small that said end portion can be bent to said angles by a cold bending said bar and without the application of heat, said end portions projecting out of said plane in opposite directions, one end portion having an upwardly-open slot, and the other end portion having a downwardly-open slot, both slots being generally parallel to the ends of said end portions and each slot being spaced from the end edge of its respective end portion a distance that the material between the slot and the end edge is accommodated between the frame wing and door wing support section of the hinge when the hinge is closed.
Claim 4
Dependent Claim
