  • Patent number: 9540870
    Abstract: There is provided a window screen configured in such a manner that first and second screens are wound around a winding shaft together with a number of dimming slats attached therebetween in which bottom bars of lower ends of both screens come into stable contact with a lower frame of a screen frame. The first and second screens and the slats attached therebetween at regular intervals so as to be freely tiltable are wound around the winding shaft, both side ends of the first screen engage guide rails so as to be freely slidable, and bottom bars guided individually by side frames are attached to lower ends of both screens. Both screens are set so that either one of the bottom bars at the lower ends thereof comes into contact with the lower frame of the screen frame in an arbitrary inclined orientation that the above-described slats may have in a state in which both screens are extended in the screen frame in a tensed manner.

  • Patent number: 7669634
    Abstract: A horizontal-pulling roll screen door for which the right/left hand can be set or changed easily and safely even by a layman and in a screen door in which a net wound up by a winding shaft of a movable stile is made capable of opening/closing by horizontal pulling. First and second caps rotatably supporting the winding shaft are mounted at the both ends of the movable stile capable of replacement by each other. A lock mechanism which can hold a locked state as necessary is provided between a connecting cylindrical shaft connected to the winding shaft and an intermediate support member connected to the first or the second cap unrotatably and removably. Rotation of the winding shaft by an urging force of a winding spring is prevented by this lock mechanism even when the both caps are removed for assembling or change of the right/left hand.

  • Patent number: 6978820
    Abstract: The invention provides a sliding screen door having a net guide that moves in association with the opening and closing movement of a net, wherein the opening and closing operation of the screen door can be performed smoothly while providing a buffering effect with an adequate resistance, without hindering the opening and closing operability of a movable edge member, by enabling a reaction force, which is required for its bending, to be used as a buffering force against the operating force of the movable edge member, the net guide being formed by connecting guide pieces. In order to do so, a net guide 12 fed out from and drawn into the lower end of the vertical frame member 6 in association with the opening and closing operation of the net 4, is provided for guiding the lower end of the net 4. The net guide 12 is formed by connecting with a tape member 16 a number of guide pieces 14 formed substantially into a U-shape with a bottom portion 14a and a stabilizing portion 14b.

  • Patent number: 6938667
    Abstract: An automatic winding screen device has a coil spring fixed to a bracket at one end of a winding box, the other end of the coil spring being fixed to a winding shaft, and a damper for alleviating impact and collision noise. Between the damper on a shaft fixed to the winding box and the winding shaft, a one-way clutch mechanism is interposed such that, when the winding shaft is rotated in a screen deploying direction, the connection between the damper and the winding shaft is cancelled while when the winding shaft rotates in a screen winding direction the damper is connected to the winding shaft.
