Abstract: A position-fixing system for a window covering, which has a roller tube, includes a variable diameter screw, a guiding portion, and an elastic member. The variable diameter screw has a working section gradually broadening in a radial direction thereof. The guiding portion extends along an inner wall of the roller tube in an axial direction thereof. The elastic member fits around the variable diameter screw, and is movable along the guiding portion. The elastic member has a meshing portion provided on an inner side thereof to mesh with the working section, and a guided portion provided on an outer side thereof to slide along the guiding portion. When the roller tube rotates in a direction, the elastic member moves along the working section and deforms, whereby to exert a gradually increasing unit tightening force to the variable diameter screw in the radial direction, dampening its rotation.

Abstract: The gym locker attached privacy cover creates a privacy area behind an arched privacy screen where a user may change clothing without being seen. The gym locker attached privacy cover attaches to gym lockers at a first support column and a second support column. An opaque screen stored without the support columns is deployed from around spindles within each support column and wires in the opaque screen cause the opaque screen to form an arch that projects away from the lockers. The user may stand within the space defined between the lockers and the arch. The first support column and the second support column may each be held in place by a set of magnets. In some embodiments, the privacy screen may be retracted by a spring-loaded ratchet and pawl arrangement or by a manually operated knob attached to the spindle.

Abstract: A door curtain assembly having a variable screening rate structure may include an internal curtain provided to be wound in a door trim and having patterns; an external curtain provided to be wound in the door trim and having a plurality of patterns; a control knob to which an upper edge portion of the internal curtain and an upper edge portion of the external curtain are fixed, and which is configured to adjust the positions of the internal and external curtains so that a rate at which the patterns of the internal curtain and the patterns of the external curtain overlap with each other may be changed, whereby the screening rate may be adjusted; and a curtain hook disposed on an upper end portion of a door frame so that the control knob may be locked to the curtain hook.

Abstract: A safety gate has a main frame, two wall-mounted assemblies, and two connecting assemblies. The two connecting assemblies are respectively and movably mounted on two opposite sides of the main frame. Each connecting assembly has a first connecting part and a second connecting part. Each wall-mounted assembly has a first pivot base and a second pivot base. Each first connecting part is rotatably and detachably connected to a corresponding first pivot base. Each second connecting part is rotatably and detachably connected to a corresponding second pivot base. By detaching and rotating one connecting assembly from the corresponding wall-mounted assembly, the main frame can be closed and opened as a gate. By detaching all the connecting parts from the corresponding bases, the main frame can be easily installed on and disassembled from a place.
