Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen door which is opened and closed by expanding and contracting a bellows-shaped stretchable insect screen supported in an opening frame by horizontal movement of a movable frame parallel to a vertical frame.

[0002]

2. Description of the Related Art When a net is not used, a screen door has been proposed in which the expandable net is shortened to either the right or left side of the opening surface so that the entire opening surface can be opened. In this case, in order to expand and contract the net, as shown in FIG. 10, one of the vertical edges of the net 106 is moved along the upper frame 101 and the lower frame 102 of the opening frame 100 so that the movable frame 105 can be moved.
And the other vertical edge portion of the net 106 is fixed to one vertical frame 104 side of the opening frame 100, and the movable frame 105 is moved in parallel with the opening surface of the opening frame 100.

In order to smoothly open or close the net 106 in FIG. 10, it is necessary that the movable frame 105 always moves smoothly in a vertical state even if a force is applied at an arbitrary height thereof. . Further, in such an expandable screen door, regardless of the position of the movable frame, that is, regardless of the expansion / contraction length of the screen, it is necessary to hold the screen so that the screen is not bent by the wind. is there.

Therefore, in the conventional screen door, the string 107 penetrating in the horizontal direction in each pleat of the net 106 is moved to the movable frame 105.
The upper frame 101 or the lower frame 102 through the rollers 108 provided in the
It is constructed so that the length of the cord 107 can be kept constant regardless of the position of the movable frame 105 by being guided to the end of the movable frame 105 and fixed. By using such a net holding means, it is possible to use a string of a constant length and to always hold the net in a tensioned state no matter where the movable frame is moved. Further, in order to stop the movable frame 105 at the position where it contacts the other vertical frame 103, that is, at the mesh closed position, for example, a locking means such as a magnet and an iron plate attracting each other is provided on the opposing surface of the vertical frame 103 and the movable frame 105. It is equipped.

[0005]

However, the above-mentioned conventional screen door does not move unless the movable frame is touched with a hand to apply a force. Therefore, in particular, when opening the net, the movable frame must be moved in the opening direction in addition to unlocking the locking means by applying a force in the opening direction with a hand on the movable frame that is difficult to reach. However, there was a problem that it was not easy to open the net. Further, in the conventional screen door, a string, which is a tension means of the screen, extends from one vertical frame to the other vertical frame through the movable frame and the upper frame or the lower frame, and both ends are connected to each vertical frame. Therefore, there is a problem that the movable frame cannot be easily removed during maintenance.

The present invention has been made in view of the above points, and locks the locking means in a screen door that is opened and closed by expanding and contracting a telescopic net supported in an opening frame by the movement of a movable frame. It is an object of the present invention to provide a screen door that can be easily opened by simply removing it.

[0007]

In order to achieve the above object, according to the present invention, the upper and lower end portions of a movable frame are respectively engaged with upper and lower horizontal frames, and the movable frame is placed in parallel with the left and right vertical frames. While holding it, the left and right vertical frames are movably supported, one end of a telescopic mesh is connected to the movable frame, the other end of the mesh is connected to one vertical frame, and the movable frame is moved. In a screen door whose mesh is opened and closed by, by connecting one ends of a plurality of cords to the movable frame, each cord is horizontally penetrated in the width direction of the mesh,
In addition, a cord retracting device that constantly urges the cord in the direction in which the cord is retracted is installed in the one vertical frame, and the movable frame moved to a position in contact with the other vertical frame is the other of the other. It is characterized in that it is provided with a locking means for locking the vertical frame.

Further, the cord retracting device includes a cord winding means, an urging member for constantly urging the cord in the winding direction of the cord, and an attachment for attaching the cord winding means and the urging member. It is characterized in that it comprises a board and a plurality of cord retracting devices are mounted in the storage groove of the vertical frame at a required interval in the height direction.

[0009]

[Operation] A string whose one end is connected to the movable frame penetrates the net,
Since the other end of the cord is always urged in the pulling direction by the cord retracting device built in one of the vertical frames, the movable frame is urged in the net opening direction. Therefore, when the lock of the locking means is released, the movable frame moves lightly in the opening direction, so that the net can be easily opened. Further, since the string is always pulled, the mesh does not bend, so that the mesh door can be smoothly opened and closed without contacting the door even in the closed state.
