Description

  The present invention relates to a screen door. More specifically, the present invention relates to a retractable screen door.

  Conventionally, a screen attached to an opening of a building is provided with a screen door to prevent a pest from entering the room when the shoji is opened. A screen door is generally a sliding door type in which a rectangular mesh material is attached to a rectangular frame and is housed in a frame.

  However, when the screen door is not used, it is preferable that the screen material is not exposed from the viewpoint of design and prevention of dirt, and in recent years, a retractable screen door that can expand and contract the screen material has been used in many cases. This storage type screen door can be stored compactly by folding the net material into a bellows shape or winding it into a roll shape.

  Incidentally, a wire is attached to the screen material of the retractable screen door so that the screen material can stand up stably. For example, a screen door is proposed that includes a guide member that guides a wire in a predetermined direction at an end portion of the mesh material, and a fixing member that is wound and slid by the wire guided by the guide member (for example, Patent Document 1). In this screen door, after the wire is wound around the fixing member, the wire returns to the guiding member again and is fixed to the guiding member. According to this screen door, the length of the wire can be adjusted by sliding the fixing member, and the tension can be adjusted.

A fixed rod (for example, a fixed rod 33 described later) fixed to the frame 13), and a movable rod (for example, a movable rod 34 described below) that can move between the door stop frame and the fixed rod in the direction of finding. A net member disposed between the fixed rod and the movable rod and having one end fixed to the fixed rod and the other end fixed to the movable rod and capable of expanding and contracting as the movable rod moves (for example, The net 4), which will be described later, and one end are fixed to the door stop frame, from the movable rod to the fixed rod A wire (e.g., wires 51, 52, and 53, which will be described later) that is stretched over the mesh material, and extends between the fixed rod and the mesh material along the fixed rod, and the wire is inserted therethrough. An attachment plate having an insertion hole (for example, a fixed-side attachment plate 6 described later) and the other end of the wire are fixed and attached to the attachment plate so as to be slidable in the extending direction thereof. There is provided a screen door comprising a fixed adjusting member (for example, a fixed adjusting member 8 described later) capable of adjusting the tension.

  The mounting plate has a long hole (for example, a long hole 62 to be described later) extending in the extending direction, and the fixing adjustment member is formed of a plate material (for example, a plate material 80 to be described later) and is screwed into the long hole. It is preferably stopped.
