A window covering can be configured to facilitate height adjustment of window covering material. In some embodiments, a handle or clips may be utilized to help maintain the position of the window covering material so that the use of an operator cord and/or exposed lift cords can be avoided or minimized.

The invention relates to a door opening and closing structure including a door plate, a transverse bar, a zipper and a pulling string. When a tension is applied on the pulling string and the tension is greater than a gravity of the transverse bar and at least a portion of the door plate, and the at least a portion of the door plate is driven by the transverse bar to move along the extension direction to form an opening. When the tension is less than the gravity of the transverse bar and the at least a portion of the door plate, the door plate is driven by the transverse bar to move along the gravity direction to reduce the opening.

A coilable shade includes a shade having a head end and a tail end. The head end includes a hanger portion. A shaft is fixed to the tail end of the shade. A shade holding device includes two pivotal portions opposite to each other. The shaft is coupled to the two pivotal portions. A portion of the shade coiled around the shaft is received in the shade holding device and is held by an elastic enveloping strap. The disadvantage of failure in retaining in a desired length in the conventional shade device that can only provide a fully extended state or a fully coiled state is, thus, solved.
