  • Publication number: 20020079277
    Abstract: A hanger for displaying clothing includes two lateral rods, a connecting bar, two side support tubes and a hang bar. The side support tubes together with the sleeves of the connecting bar are tightly screwed with the lateral rods at the same time, and the combination of the hang bar and the inner tubes in the side support tubes is effected by mutual engagement of insert button and insert hole, easy to be detached for packing or storing. Besides, the U-shaped plate under the side support tube forms a gap of a certain height for the friction wheels to expand outward to rest against the bottom side of the inner tube to stabilize the whole structure, when the inner tube is pressed down Thus the hanger for displaying clothing needs only a small space and stands very stably.
