Two further door panels each includes a post coupled to the respective posts of the door panel with a flexible hinge member. The flexible hinge member may be solidly secured between the posts of the door panels with such as mold injection processes, to prevent the flexible hinge member from being moved relative to the posts of the door panels. One or more boards may further be secured between the posts with catches and secured to the plate with couplers.

Abstract: A screen door includes two stiles and two beams secured together to form a rectangular frame, and to define an opening within the frame, and a screen received in the opening of the frame. The stiles and the beams each may include one or more longitudinal groove to receive a spline which may force and engage the screen into the longitudinal groove of the stiles and the beams. The stiles and the beams each may include one or more longitudinal flanges extended into the longitudinal grooves and to retain the spline and the screen within the longitudinal grooves of the stiles and the beams, and to solidly secure the screen to the frame.

Abstract: A shutter device includes a frame having two stiles and two beams secured together, the stiles each has a groove to receive a rail, the rails each includes a number of orifices, and a number of blades having end projections engaged into the orifices of the rails, to rotatably secure the blades between the rails and the stiles. A control device may be coupled to the blades to move or to open and close the blades relative to the frame. The orifices may be quickly and precisely formed in the rails, with such as molding or punching processes, for allowing the blades to be quickly manufactured and assembled to the stiles with the rails.

Abstract: A sliding door includes two or more door panels, and one or more resilient couplings having the side stops slidably engaged in the side channels of the door panels for resiliently coupling the door panels together and for allowing the door panels to be adjusted relative to each other. The door panels each includes less than 78% by weight of a foamable material, and more than 20% by weight of wood chips or particles mixed within the foamable material, and less than 2% by weight of a vulcanizing agent, for allowing the door panels to be adjusted to different weights.

Abstract: A foldable door assembly includes a frame member and a jamb member, a latch slidably received in the jamb member and coupled to the jamb member with a spring member. An end beam is engageable into the frame member, and another end beam is coupled to the latch, and a number of door panels are coupled between the end beams. The spring member may resiliently and flexibly couple the latch and thus the other end beam to the jamb member for allowing the foldable door assembly to be adjusted to various lengths and to be attached to the door frames of different sizes or widths.

Abstract: A sliding door assembly includes a number of door panels slidably engaged with a track and a leader end secured to one end of the door panels. A retaining device forms a channel for receiving the leader end and has a pair of opposite resilient stops trapezoidal in cross-section and extended inwardly into the channel for engaging with the leader end and for retaining the leader end within the retaining device. The retaining device may be secured to a supporting abutment, usually a wall member, or may be secured to and moved in concert with the leader member of another sliding door subassembly for coupling the sliding door subassemblies together.

Abstract: A shower screen includes a guide rod and a guide bar secured between the top and the bottom portions of the posts. A screen member has an upper portion slidably secured to the guide rod and has two sides secured to two beams. The guide bar includes a wall extended upward from a base. The beams each has a retaining member secured to the bottom for slidably engaging with the wall of the guide bar and for preventing the screen member from being disengaged from the guide bar. The base includes an upper tapered surface for guiding water into a bath tub.

The safety member may enclose the gap for preventing a user from being hurt between the door panels.

Abstract: A improved folding shower door assembly and related method of manufacture therefor are disclosed in which rigid panels with living hinges therebetween are supported by a horizontal track, with the shower door assembly mating at both sides thereof by removably inserting plastic closure channels at the sides of the shower door into retaining members mounted on opposing walls. The shower door assembly consists essentially of a plurality of semi-rigid panels which may be molded together in a single molding operation or by assembling panels together, with living hinges being located intermediate each adjacent pair of semi-rigid panels. A bathtub trim member located on top of the outer lip of the bathtub functions to retain the bottom edge of the shower door assembly, thereby preventing it from moving out over the edge of the bathtub and retaining water within the bathtub.

The assembly also includes a folding door formed of an array of interconnected, parallel, vertically extending polyvinyl chloride slats arranged in side by side relation. The slats have small staple fibers substantially uniformly distributed throughout the body thereof to give the slats a translucent sandy appearance and feel. Each slat in the arry preferably is corrugated to provide a number of integral parallel segments. Each slat has an integral side folding hinge extending along the length of one side thereof and a hinge-receiving slot or groove along the length of the opposite side of the slat. The slats are interconnected through the side hinges and grooves.

Abstract: A polyvinyl chloride venetian blind is provided which has a number of corrugated, translucent slats. The slats have staple fibers in their composition that gives them a sand or granite textured appearance and feel, so that the venetian blind has more natural and aesthetic appeal. The slats are formed by an extrusion process utilizing a mixture of polyvinyl chloride, titanium dioxide, plasticizer, tribasic lead sulfate, stearic acid and dyed staple fibers having a length of less than about 2 mm.

Abstract: A door includes two door panels pivotally coupled together so that the door panels are rotatable relative to each other. A roller is disposed on an upper end of two distal posts and is guided to slide along a guide rail. A cylinder is fixed on each end of one of the distal posts. A rod is fixed to the roller and extends through an upper cylinder. The lower portion of lower cylinder is rotatably received in a hole and can be easily disengaged from the hole when the distal post is pulled upward.
