A screen system for deployment over a surface is disclosed herein. The screen system comprises a first screen structure (550) and a second screen structure (553). Each screen structure comprises a panel element (544a,554b) attached to at least one support element (501a,501b,503a,503b), wherein the at least one support element and the panel element are attached to and configured to be rollable about a rotor (516a,516b) configured to rotate about a longitudinal axis to provide for extension and retraction thereof along a direction generally perpendicular to the longitudinal axis. The rotor of the second screen structure is configured to be moveable relative to the rotor of the first screen structure.

A robot can include a partition wound about a partition rotation axis extending in a first direction, a plurality of body parts surrounding an accommodation space in which the partition is accommodated, and a roller part having a plurality of rollers rotatably mounted on at least some of the plurality of body parts.

A child safety gate with a flexible retractable barrier part (3) wound on a rotatable roller (R) includes a locking device (10) connected to the rotatable roller (R). In an unlocked position, the locking device (10) allows extraction of the barrier part (3) in an unwinding direction of the roller (R). In a locked position, the locking device (10) prevents further extraction of the barrier part (3) in the unwinding direction. The locking device (10) includes an actuator (11) movable between a first position corresponding to the unlocked position, and a second position corresponding to the locked position. Upon actuating the actuator (11) in the closed gate position, the barrier part (3) is reversed in a direction opposite the pull-out direction to provide extra tensioning of the barrier part (3).

A magnetic track assembly including an elongate channel having an open side, an end wall, and two parallel side walls; a first magnet disposed within the elongate channel near an interior side of the end wall; a compartment defined within the elongate channel spaced from the first magnet; and a screen receiver disposed within the compartment and including a second magnet arranged facing the first magnet. In the magnetic track assembly, the first and second magnets are of opposite polarity and the screen receiver is loosely disposed within the compartment such that a magnetic bond is intact between the first and second magnets when the first and second magnets are close together and the magnetic bond is broken when the first and second magnets are pulled apart.

The disclosure belongs to the field of gates and discloses a retractable baby gate. The retractable baby gate includes at least a piece of gate fabric; a roller, mounted on one side of the gate fabric, wherein a rolling shaft is coaxially arranged in the roller, one end of the gate fabric is fixed to the rolling shaft and winds the periphery of the rolling shaft, a longitudinal opening through which the gate fabric comes in and goes out is formed in the peripheral surface of the roller, a shell is fixedly connected to the upper end of the roller, and a base fixedly connected to a mounting fixed surface is connected to the lower end of the shell; and a control portion, arranged in the shell to control rotation and locking of the rolling shaft, wherein the control portion includes a gear coaxially connected to the rolling shaft.
