Abstract
TYhe curtain drawing device providing either manual or automatic drawing of a curtain comprises an electric motor, a curtain rod which is driven rotatably by the motor, an exteriorly-protruding longitudinally-extending spiral element attached to the outer circumference of the curtain rod and a plurality of rings through which the curtain rod passes, each of which have a diameter larger than the diameter of the curtain rod, so that the curtain which is suspended from the rings can be drawn manually or by rotation of the curtain rod. An automatically-releasing tassel holder which can be operated by remote control may be provided.
Claims4
A curtain drawing device for a curtain providing either manual or automatic drawing of said curtain comprising:
- an electric motor;
- a curtain rod, which is rotatably mounted and connected to said electric motor so that said electric motor can drive said curtain rod rotatably;
- an exteriorly-protruding longitudinally-extending spiral element attached to an outer circumference of said curtain rod, said spiral element encircling said curtain rod;
- a plurality of rings, through which said curtain rod passes, each of said rings having a larger diameter than a diameter of said curtain rod including said spiral element, said curtain being attachable to said rings for suspension from said curtain rod, and
- a tassel band and a solenoid-actuated tassel holder, which holds one end of said tassel band and which is structured to release said tassel band when said solenoid-actuated tassel holder receives an external electrical signal.
A curtain drawing device for a curtain providing either manual or automatic drawing of said curtain comprising:
- an electric motor;
- a curtain rod, which is rotatably mounted and connected to said electric motor so that said electric motor can drive said curtain rod rotatably;
- an exteriorly-protruding longitudinally-extending spiral element attached to an outer circumference of said curtain rod, said spiral element encircling said curtain rod;
- a plurality of rings, through which said curtain rod passes, each of said rings having a larger diameter than a diameter of said curtain rod including said spiral element, said curtain being attachable to said rings for suspension from said curtain rod, and
- a tassel band having a first and a second hook at each end of said tassel band and a tassel holder comprising a receptacle and a retaining pin on which said second hook is caught, a fixing pin with a connected ring on which said first hook is engagable, said fixing pin being securable but slidable in said receptacle of said tassel holder, and an exteriorly-actuated solenoid surrounding a movable shaft extending in a hole provided in said tassel holder;
- said movable shaft being engageable in said fixing pin to secure said fixing pin to hold said fixing pin in said receptacle, said movable shaft being biased downwardly to engage said fixing pin by a spring and being biased upwardly to release said fixing pin and said curtain on energizing said solenoid.
