This motorized carriage for opening/closing a curtain is able to move along a rail thanks to a friction wheel driven by an electric motor and pivot mounted in a casing containing this electric motor. The casing is provided with at least two members for suspending it from the rail or from the rod, which include a support and/or a base element and at least one pivoting roller. The casing is equipped with at least one housing for partially accommodating and reversibly immobilizing each suspension member, so that the pivoting rollers or the shoes of the suspension members are mounted removably on the casing. The support is mounted, removably and via a rotational movement (F4), in the housing. Elements allow the support to be immobilized about its axis of rotation. The movement assembly (E) includes a casing and at least two sets of two suspension members.

The present invention relates to a curtain control system and a curtain control method. When a controller receives a curtain-releasing signal, a braking module releases a curtain so as to lower it, a current position detecting module detects an absolute position of the curtain, and the controller calculates a current velocity and a current acceleration of the curtain according to a variation per unit time of the absolute position. When the current velocity is equal to zero or the current acceleration is smaller than zero, the controller controls a motor to lift the curtain or controls the braking module to hold the curtain at a current position. Accordingly, the present invention uses the absolute position to calculate the current velocity and the current acceleration of the curtain so as to determine whether the curtain has encountered an obstacle.

A system for opening and closing a curtain on a rod or rail, includes a driven wheel coupled to a motor within a housing and protruding from the housing in frictional engagement with the rod or rail and a suspension system including a plurality of support members, each of the plurality of support members configured for sliding or rolling contact with the rod or rail and a linkage extending along a suspension axis and connecting a support member of the plurality of support members to the housing to suspend the housing from the support member. During installation, the system is configured for the user to select the support member from the plurality of support members and to couple the support member to the housing, and the driven wheel is rotated by the motor to advance the housing along the rod or rail with the housing suspended from the support member.

A curtain control system, installed in a curtain, comprises a sensing module, a processing module, and a motor control module. When a processing unit of the processing module determines that a rotation angle common to a plurality of panel holders falls within a specific range or that a change in the rotation angle reaches a specific value, and the rotation angle is not equal to a preset angle, the motor control module drives a travel motor and a tilt motor to operate simultaneously. In this manner, the waiting time for curtain adjustment during user operation can be reduced.

A shower curtain closure device for automatically closing a shower curtain includes a housing having a front side, a back side, and a peripheral wall extending therebetween, defining an interior space. The front side has a shower rod recess therein that is configured to receive a portion of a shower curtain rod. A spool is positioned within the interior space. A cord having a spool end and a clip end is coupled to the housing. The spool end is attached to the spool and the cord is wrapped around the spool. The spool rotates to wrap and unwrap the cord, such that the cord retracts into and extends from the housing. A curtain clip is attached to the clip end that can removably engage a shower curtain ring. A motor is positioned within the interior space. The motor is coupled to the spool, rotating the spool to retract the cord.
