Patent number: 5010942Abstract: This invention relates to a retaining bracket for a window/bathroom curtain which has a base body and a pushing member. The pushing member has projecting tabs located in each of its two lateral sides. By urging the pushing member against the base body, a clamping force will be produced to clamp a fixed edge of the curtain. The pushing member can also be moved downwardly and, by inserting the tabs into corresponding holes in the base body exert a clamping force in this position. In both upper and the lower positions the pushing member can exert a clamping force on the curtain. In addition, a hook, which is attached to a side of the base body, will retain the curtain in a folded position and will also prevent the window or bathroom curtain from being pulled excessively.Type: GrantFiled: January 30, 1990Date of Patent: April 30, 1991Inventor: Wu-Hu Hung
