Abstract:
1. A sliding screen door comprising: a frame body; an operating doorframe mounted to the frame body for movement in a horizontal direction; a pleated screen having vertical pleats, wherein one end of the screen is fixed to an elongated endplate at a vertical frame member of the frame body and another end of the screen is attached to the operating doorframe, whereby the screen is freely movable in the frame body to be fully closed by movement of the operating doorframe away from the vertical frame member; a wire having one end fixed to a wire adjusting mechanism at the vertical frame member and being horizontally inserted into the screen, and wherein the wire extends into the operating doorframe and a guide member is provided in the operating doorframe to guide the wire downward therein; a sinker mounted to an end of the wire in the operating doorframe and freely vertically movable in the operating doorframe, whereby the weight of the sinker stretches the wire; and a spring member in the operating doorframe and surrounding the wire, the spring member being positioned between the sinker and a contacting portion of the operating doorframe, wherein the wire adjusting mechanism is adjustably mounted to the vertical frame member, and wherein the mounting position of the wire adjusting mechanism on the vertical frame member is adjusted such that the spring member is compressed between the sinker and the contacting portion when the screen is fully closed, whereby a resilient expansion force of the spring applies a stretching force to the wire, wherein the wire adjusting mechanism comprises a guide part having a first wire connection portion and attached to the vertical frame member, and an adjusting member having a second wire connection portion and capable of sliding along a longitudinal direction of the vertical frame member and being attached to the vertical frame member, wherein the first and second wire connecting portions are longitudinally bent in opposite directions to hook the wire, and wherein the wire is passed through the guide part, bent by the guide part to extend toward the adjusting member in the longitudinal direction of the vertical frame member, and fixed to the first or second wire connection portion of one of the guide part and the adjusting member, wherein the vertical frame member comprises a longitudinal sliding groove slidably housing the guide part and the adjusting member, and opening in a direction facing the screen, and wherein the elongated endplate of the screen is detachably mounted to the vertical frame member so as to cover the guide part and the adjusting member in the sliding groove.
