Abstract

An I-beam having a web curved in two dimensions is used to provide an enhanced stiffness to weight ratio for molded plastic hangers. The I-beam includes first and second generally parallel flanges which extend in a longitudinal direction. The flanges are joined by a curved web, which is defined in part by first and second radii of curvature, wherein the radii are nominally orthogonal to each other.

Claims (21)

1. An improved hanger, said hanger comprising;

(a) a hanger hook for suspending the hanger from a support, said hook defining a center axis for said hanger;

(b) a support bar suspended from said hook, said support bar having first and second ends and first and second longitudinally extending flanges spaced from one another and extending outwardly from said hook, said flanges joined by a curved web member having a first axis of curvature; said curved web member extending from one side of said center axis at said first and second ends to an opposite side of said center axis, said curved web having a second axis of curvature orthogonal to said first axis curvature to provide enhanced resistance to flexure;

(c) means for engaging a garment mounted on said support bar.

2. An improved hanger as claimed in claim 1 , wherein said hanger is integrally formed of plastic with said first and second flanges of said support bar being generally parallel to each other.

3. An improved hanger as claimed in claim 1 , wherein said first axis of curvature of said curved web of said hanger defines a constant radius along the length of the curved web.

4. An improved hanger as claimed in claim 1 , wherein said second axis of curvature of said curved web is constant along the length of said curved web.

5. An improved hanger as claimed in claim 1 , wherein said first and said second axes of curvature define a constant radii along the length of the curved web.

6. An improved hanger as claimed in claim 5 , wherein said second axis of curvature defines a curved cylindrical axis, with the curvature of the cylindrical axis defined by said first axis of curvature.

7. An improved pinch grip hanger, said hanger comprising;

(a) a hanger hook, said hook defining a center axis for said hanger;

(b) a support bar suspended from said hook, said support bar having first and second ends and first and second longitudinally extending flanges spaced from one another and extending outwardly from said hook, said flanges joined by an curved web member; said curved web member extending from one side of said center axis at said first and second ends to an opposite side of said center axis, said curved web providing enhanced resistance to flexure; and

(c) a pinch grip mounted on said support bar at each thereof, said pinch grip having first and second pinch jaws to suspend a garment between said first and second pinch grip jaws in normal use.

8. An improved pinch grip hanger as claimed in claim 7 , wherein said curved web member hanger is integrally formed of plastic with said first and second longitudinally extending flange members, said curved web defining a second curvature orthogonal to said first curvature to provide enhanced strength and stiffness for said support bar.

9. An improved pinch grip hanger as claimed in claim 8 , wherein said hanger is integrally formed of plastic with said first and second flanges of said support bar being generally parallel to each other.

10. An improved pinch grip hanger as claimed in claim 8 , wherein said hanger is integrally formed of plastic with said first and second flanges of said support bar being generally parallel to each other, with said first pinch grip jaw integrally molded with said support bar at a first end of said curved web, and said second pinch grip jaw secured thereto by a resilient spring along said pivot axis.

11. An improved pinch grip hanger as claimed in claim 9 , wherein said curved web member hanger extends from the first jaw member on one side of said center axis to an opposite side of said center axis at said hook member.

12. An improved pinch grip hanger as claimed in claim 11 , wherein said curved web member and said flanges support an offset mounting of said guard member and said pinch grip to said support bar, such that said first pinch grip jaw is offset from the center axis of the hanger by approximately one half the depth of the arc of said curved web to thereby reduce the depth of the hanger in normal use.

13. An improved pinch grip hanger as claimed in claim 8 , wherein said hanger is nestable with a second improved pinch grip hanger.

14. An improved pinch grip hanger as claimed in claim 13 , wherein said pinch grips include a user actuation portions and garment engagement ends, with said garment engagement portions of a first of said improved pinch grip hangers receivable in said user actuation portions of a second of said pinch grip hangers to nest the hangers.

15. An improved pinch grip hanger as claimed in claim 7 , further comprising a guard means extending from one side of said center axis to a position on the opposite side of said center axis, such that when two or more improved pinch grip hangers are suspended from their respective hooks with garments clamped in their respective pinch grips, the guard means preventing accidental actuation of the pinch grips and release of the garments hangers when two of said hangers are pressed together.
