Abstract
An adjustable curtain rod assembly includes a rod member and an adjustment mechanism coupled to an end of the rod member. The adjustment mechanism is operable to adjust a length of the rod assembly and has a clutch mechanism that prevents over-extension of the rod assembly during mounting.
Claims17
An adjustable curtain rod assembly comprising:
- a rod member;
- and
- an adjustment mechanism coupled to an end of the rod member, the adjustment mechanism operable to adjust a length of the rod assembly and having a clutch mechanism that prevents over-extension of the rod assembly during mounting;
- wherein the clutch mechanism includes first and second clutch plates, the clutch plates being operable to transmit torque therebetween and extend the rod assembly when a first torque is applied to one of the clutch plates, and to prevent transmission of torque therebetween when a second torque of the same direction as the first torque, but of greater magnitude than the first torque, is applied to one of the clutch plates, thereby preventing extension of the rod assembly.

An adjustable curtain rod assembly comprising:
- a rod member;
- and
- an adjustment mechanism coupled to an end of the rod member, the adjustment mechanism operable to adjust a length of the rod assembly and having a clutch mechanism that prevents over-extension of the rod assembly during mounting;
- wherein the rod member is curved, and wherein the adjustment mechanism is operated by applying torque to a handle rotatable relative to the rod member;
- wherein the adjustment mechanism includes a mounting shaft operable to engage a mounting plate abutting a support structure, the mounting shaft being extendable and retractable relative to the rod member;
- and
- wherein the adjustment mechanism further includes a rod insert positioned in the end of the curved rod member and receiving the mounting shaft such that the mounting shaft cannot rotate relative to the curved rod member.

An adjustable curtain rod assembly comprising:
- a rod member;
- and
- an adjustment mechanism coupled to an end of the rod member, the adjustment mechanism operable to adjust a length of the rod assembly and having an overrunning clutch mechanism operable to permit extension of the rod assembly to a first length that creates a first compressive force on a support surface to which the rod assembly is being coupled, and that prevents extension of the rod assembly to a second length longer than the first length and that would create a second compressive force greater than the first compressive force on the support surface;
- wherein the clutch mechanism includes first and second clutch plates, the clutch plates being operable to transmit torque therebetween and extend the rod assembly when a first torque is applied to one of the clutch plates, and to prevent transmission of torque therebetween when a second torque of the same direction as the first torque, but of greater magnitude than the first torque, is applied to one of the clutch plates, thereby preventing extension of the rod assembly.
