Abstract
Abstract A closet accessory in the form of a hat, coat and shoe rack of the type transportable in a disassembled condition, including a number of hollow tubing structural members and with T-joints, between base members and upright members for example, of particularly simple and rugged construction formed by flattening an end portion of a hollow tube, curving it to conform to the curve of a tube to which it is to be joined, bending off the partially flattened and unflattened portions of the first tube at approximately right-angles to the round flat portion, and providing in the bend ridges with a curvature opposite to the bend. The flattened and formed tubing section described above is fastened, by spot welding for example, to the second piece of tubing which it is shaped to conform with to form a strong Tshaped tubing structure.

Claim 1
Independent Claim
290 words
A closet accessory comprising, a pair of inverted U-shaped metal tubular elements of circular cross section, said U-shaped tubular elements each having joined thereto an upwardly extending tubular section, a pair of upright tubular elements engaging respectively said upright tubular sections, a top tubular crosspiece joining said upright tubular sections and a bottom crosspiece joining said inverted U-shaped tubular elements, the joinder of each said U-shaped tubular element and the corresponding upwardly extending tubular section Consisting of a T-shaped junction constructed at the center of said U-shaped metal tubular elements between a first and a second of such tubular elements, the first of said tubular elements being substantially undeformed in the area of the junction and the second of such tubular elements being flattened at its end, the flattened portion thereof being bent in the shape of a sector of a cylinder subtending at least 50* and not more than about 200* to conform to the cross-sectional shape of said first tubular element, there being a partially flattened portion of said second tubular element adjacent said flattened portion and a bend of approximately 90* between said flattened portion and said partially flattened portion portion, the bend line of said bend being along a line approximately parallel to the axis of said cylinder, there further being at least one ridge bent in said second tubular element across said bend line, said ridge having a curvature opposite to that of the bend at said bend line, and a total length substantially less than the length of said flattened portion, the flattened portion of said upwardly extending tubular section being secured to the wall of said U-shaped tubular element near the center thereof and said T-shaped junction substantially supporting said closet accessory structure.

A closet accessory comprising, a pair of inverted U-shaped metal tubular elements of circular cross section, said U-shaped tubular elements each having joined thereto an upwardly extending tubular section, a pair of upright tubular elements engaging respectively said upright tubular sections, a top tubular crosspiece joining said upright tubular sections and a bottom crosspiece joining said inverted U-shaped tubular elements, the joinder of each said U-shaped tubular element and the corresponding upwardly extending tubular section Consisting of a T-shaped junction constructed at the center of said U-shaped metal tubular elements between a first and a second of such tubular elements, the first of said tubular elements being substantially undeformed in the area of the junction and the second of such tubular elements being flattened at its end, the flattened portion thereof being bent in the shape of a sector of a cylinder subtending at least 50* and not more than about 200* to conform to the cross-sectional shape of said first tubular element, there being a partially flattened portion of said second tubular element adjacent said flattened portion and a bend of approximately 90* between said flattened portion and said partially flattened portion portion, the bend line of said bend being along a line approximately parallel to the axis of said cylinder, there further being at least one ridge bent in said second tubular element across said bend line, said ridge having a curvature opposite to that of the bend at said bend line, and a total length substantially less than the length of said flattened portion, the flattened portion of said upwardly extending tubular section being secured to the wall of said U-shaped tubular element near the center thereof and said T-shaped junction substantially supporting said closet accessory structure.
