Abstract
Abstract A clothes hanger particularly for skirts or trousers embodies a cross member provided near its center with a suspension hook. Near opposite ends, the cross member carries two articulated clamps for gripping suspended clothes. The gripping action of each clamp, on the clothes, is developed in a gradual way by rotating a cam-shaped spreading element lodged within the upper extensions of the clamps. Simplicity and economy of manufacturing are featured.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
159 words
A clothes hanger comprising a cross member having a central suspension hook, a pair of clamps carried by the opposite ends of the cross member and each having a pair of opposing substantially rigid claws in articulated relationship with arm extensions of the claws projecting above the points of articulation of the claws, and a pair of cam-shaped rotatable spreading elements one for each clamp lodged between said arm extensions of the clamps to thereby spread the arm extensions apart and draw said claws of the clamps together in gripping engagement on an article of clothing inserted between said claws, and each spreading element comprising an inside hollow portion formed of resilient material positioned perpendicular to the arm extensions of each clamp, an operating arm on said inside hollow portion, and two pegs eccentrically positioned on said inside hollow portion protruding perpendicularly from the plane of said portion and acting simultaneously on the internal surfaces of both arm extensions.
Claim 2
Dependent Claim
159 words
A clothes hanger comprising a cross member having a central suspension hook, a pair of clamps carried by the opposite ends of the cross member and each having a pair of opposing substantially rigid claws in articulated relationship with arm extensions of the claws projecting above the points of articulation of the claws, and a pair of cam-shaped rotatable spreading elements one for each clamp lodged between said arm extensions of the clamps to thereby spread the arm extensions apart and draw said claws of the clamps together in gripping engagement on an article of clothing inserted between said claws, and each spreading element comprising an inside hollow portion formed of resilient material positioned perpendicular to the arm extensions of each clamp, an operating arm on said inside hollow portion, and two pegs eccentrically positioned on said inside hollow portion protruding perpendicularly from the plane of said portion and acting simultaneously on the internal surfaces of both arm extensions.
Claim 3
Dependent Claim
58 words
A clothes hanger as defined in claim 1, wherein one of the arm extensions of each clamp is provided with a longitudinal open slit to lodge and guide the operating arm of the spreading element, and the other arm extension is provided with a longitudinal closed slot to partially lodge the disc rim of the inside hollow portion.
Claim 4
Dependent Claim
25 words
A clothes hanger as defined in claim 2, wherein the length of the slit is greater than the length of the disc portion lodged therein.
Claim 5
Dependent Claim
23 words
A clothes hanger as defined in claim 3, wherein the inside hollow portion is formed as a ring elongated toward said operating arm.
Claim 6
Dependent Claim
116 words
A clothes hanger comprising a cross member of injected plastics material having a central suspension hook, a pair of clamps integral with the opposite ends of the cross member, each clamp having a pair of opposing substantially rigid claws held in articulated relationship by a web of the same plastics material and biasing the clamp open when the web is in a relaxed condition, said claws having arm extensions above said web, and a pair of cam-shaped rotatable spreading elements one for each clamp lodged between said arm extensions of the claws to thereby spread the arm extensions apart and draw said claws together in gripping engagement on an article of clothing inserted between said claws.
Claim 7
Dependent Claim
116 words
A clothes hanger comprising a cross member of injected plastics material having a central suspension hook, a pair of clamps integral with the opposite ends of the cross member, each clamp having a pair of opposing substantially rigid claws held in articulated relationship by a web of the same plastics material and biasing the clamp open when the web is in a relaxed condition, said claws having arm extensions above said web, and a pair of cam-shaped rotatable spreading elements one for each clamp lodged between said arm extensions of the claws to thereby spread the arm extensions apart and draw said claws together in gripping engagement on an article of clothing inserted between said claws.
Claim 8
Dependent Claim
52 words
A clothes hanger as defined in claim 5, wherein each spreading element comprises a disc portion perpendicular to the arm extensions of each clamp, an operating arm for said disc portion, and at least a cam element attached to the disc portion and operating on the internal surfaces of both arm extensions.
