Abstract
Abstract A comb and a method of making a comb having a handle including two main surfaces having a common edge and a plurality of substantially parallel, spaced apart, elongated teeth extending from the main edge. Each tooth comprises identical first and second sections, each including a planar base portion. All of the first sections are aligned and all of the second sections are aligned and the planar base portions of the first and second sections of each tooth abut and are transversely offset with respect to each other by a distance less than the distance between adjacent aligned sections. In this way the resulting spacing between adjacent teeth is less than the tooth sections spacing.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
A comb comprising: a handle having two main surfaces having a common main edge and a plurality of substantially parallel, spaced apart, elongated teeth extending from the main edge, each tooth comprising both a first and a second section each section including a planar base portion and a convex portion wherein all of the first sections are aligned and all of the second sections are aligned and the planar base portions of the first and second sections are aligned and the planar base portions of the first and second sections of each tooth abut to each other and are offset by a distance less than the distance between adjacent aligned sections, so that the teeth are not symmetrical with respect to the plane which includes the planar base portions.
Claim 2
Dependent Claim
129 words
A comb comprising: a handle having two main surfaces having a common main edge and a plurality of substantially parallel, spaced apart, elongated teeth extending from the main edge, each tooth comprising both a first and a second section each section including a planar base portion and a convex portion wherein all of the first sections are aligned and all of the second sections are aligned and the planar base portions of the first and second sections are aligned and the planar base portions of the first and second sections of each tooth abut to each other and are offset by a distance less than the distance between adjacent aligned sections, so that the teeth are not symmetrical with respect to the plane which includes the planar base portions.
Claim 3
Dependent Claim
21 words
The comb according to claim 1, wherein the amount of offset is less than half the maximum width of each section.
Claim 4
Dependent Claim
24 words
The comb according to claim 1, wherein the handle has a planar portion having an aperture therein and a magnifying lens in the aperture.
Claim 5
Dependent Claim
35 words
The comb according to claim 1, wherein the tooth sections are equally spaced apart and the distance between the edges of adjacent first and second tooth sections at the main edge is about 0.10 mm.
Claim 6
Dependent Claim
33 words
The comb according to claim 1, wherein the width of each tooth section gradually tapers toward the outermost end and the height of each tooth section tapers gradually towards the outermost end thereof.
Claim 7
Dependent Claim
48 words
The comb according to claim 1, wherein the handle comprises two half sections each comprising one main surface and an opposing planar surface and bearing an aligned set of tooth sections with the planar bases thereof in the same plane as the planar surface of the half section.
Claim 8
Dependent Claim
22 words
the comb according to claim 6, wherein each half section with the borne set of tooth sections comprises an integral plastic member.
Claim 9
Dependent Claim
23 words
The comb according to claim 7, produced by permanently affixing the two half sections together with the offset first and second tooth sections.
Claim 10
Dependent Claim
29 words
The comb according to claim 7 wherein one half section is pivotally mounted so that the abutting tooth sections may be spaced apart to facilitate cleaning of the comb.
Claim 11
Dependent Claim
99 words
A comb comprising a plurlity of substantially parallel closely spaced elongated teeth, each tooth having a sharp edge and a rounded edge and having a cross section such that the cross section of each adjacent pair of teeth is substantially symmetric about a point midway between the adjacent pair of teeth but not symmetric about any plane, whereby a hair passing between the adjacent pair of teeth is scraped on one side by the sharp edge of one tooth of the pair and pressed on an opposite side by the rounded edge of the other tooth of the pair.
Claim 12
Dependent Claim
99 words
A comb comprising a plurlity of substantially parallel closely spaced elongated teeth, each tooth having a sharp edge and a rounded edge and having a cross section such that the cross section of each adjacent pair of teeth is substantially symmetric about a point midway between the adjacent pair of teeth but not symmetric about any plane, whereby a hair passing between the adjacent pair of teeth is scraped on one side by the sharp edge of one tooth of the pair and pressed on an opposite side by the rounded edge of the other tooth of the pair.
Claim 13
Dependent Claim
38 words
The comb of claim 10 in which the teeth are joined to a main edge, whereby the hair passing between the adjacent pair of teeth is scraped on a third side of the hair by said main edge.
