2. Description of the Related Art A foldable type mesh door in which an accordion-type elastic net by pleating is attached to a mesh door frame and the net is expanded and contracted in the lateral direction to open and close has been well known. By the way. When applying such a folding screen door to a screen door of a type in which a frame inner surface in a building opening is directly attached to a wooden frame or the like, an upper frame member and a lower frame forming the screen frame are used. In the member, it is necessary to guide the upper and lower ends of the net and the upper and lower ends of the operating frame attached to the tip of the net.

However, the above-mentioned building openings have various sizes, and it is necessary to adjust the size of the screen frame in accordance with the size of each opening.
Therefore, the upper and lower end guides of the operating frame by the upper and lower frame members also need to be able to be smoothly guided despite a slight change for adjusting the height of the screen frame. On the other hand, especially with regard to the lower frame member, if the height of the lower frame member is increased due to the operation frame, the guide of the net, or some other reason,
There is a risk that a person passing there may trip, and therefore it is required to make the lower frame member as low as possible. Therefore, the guide wall for preventing the net and the operating frame from coming off the lower frame member is also made as low as possible.

As described above, in order to smoothly guide the upper and lower ends of the operating frame by the upper and lower frame members of the screen frame even if the height of the screen frame is slightly changed, the operating frame is moved up and down by the screen frame. It is necessary to allow a slight allowance in the direction for guiding, and the guide wall for preventing the net and the operating frame from separating from the lower frame member should be made as low as possible. At some times, the lower end of the frame is likely to cross over the guide wall and come off the guide groove of the lower frame member.

[0005]

As described above, the technical problem of the present invention is to guide the upper and lower ends of the accordion type net and the operating frame attached to the ends thereof by the guide grooves of the upper and lower frame members. In a folding mesh door for directly attaching to the opening of a building where the net is opened and closed by the operating frame, the operating frame is guided by the screen frame with a slight margin in the vertical direction, and the lower end of the net and the operating frame are also guided. Another object of the present invention is to obtain a foldable screen door which can prevent the lower end of the operating frame from coming off the guide groove of the lower frame member even if the guide wall of the lower frame member that guides the lower frame member is made as low as possible.

Another technical problem of the present invention is to prevent the operation frame from being separated from the guide groove of the lower frame member by easily adjusting the structure even after the folding screen door is constructed. Is to get. Another technical problem of the present invention is to regulate vertical movement of an operating frame in a folding screen door of a type in which a frame inner surface such as a wooden frame of a building opening is directly attached to a flat portion. Thus, the folding screen door is provided in which the guide wall provided on the lower frame member for guiding the net and the lower end of the operating frame can be made as low as possible in order to prevent tripping.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the folding screen door of the present invention comprises an accordion-type telescopic net by pleating the upper frame member, the lower frame member and the left and right sides. It is installed in a screen door frame made of a frame member so that it can be opened and closed in a laterally openable manner. In a folding screen door for directly attaching to the opening of a building that opens and closes the net, the distance between the upper frame member and the lower frame member is set within a range in which the operating frame can be guided in the guide grooves of the upper and lower frame members. It is configured to be adjustable, and a stopper for abutting against the upper frame member and restraining the upward movement of the operating frame is attached to the upper part of the operating frame so that the vertical position can be adjusted.

[0008]

In the screen door, since the distance between the upper frame member and the lower frame member can be adjusted within a range in which the operating frame can be guided by the guide grooves of the upper and lower frame members, the operating frame can be vertically moved by the screen frame. The screen frame is guided with a slight margin in the direction, and the screen frame can be adapted to the size of the building opening within the range. Further, a stopper for hitting the upper frame member to restrain the upward movement of the operating frame is attached to the upper portion of the operating frame so that the vertical position can be adjusted, so that the vertical movement of the operating frame can be restricted. Even if the guide wall of the lower frame member that guides the lower end of the operating frame is lowered, it is possible to prevent the lower end of the operating frame from coming off the guide groove of the lower frame member.
Moreover, in order to prevent tripping, the height of the guide wall of the lower frame member can be reduced to the maximum.

Further, as can be seen from FIG. 5, the upper and lower ends of the net 2 can be fitted into the guide grooves 4 and 5 of the upper frame member 1a and the lower frame member 1b of the screen frame 1, respectively.

The operating frame 3 has a net accommodating portion 3a in the form of a groove formed in the mounting portion of the net 2.
When the screen door is fully opened, the folded net 2
Is housed between the net housing portion 3a of the operating frame 3 and the side frame member 1c. This operation frame 3 is manually operated, as shown in FIG. 2, with its upper and lower ends being the upper frame member 1a and the lower frame member 1.
Although it is not shown in the drawing, it is provided with a pair of rolling wheels 6 and 6 at the lower end of the operating frame 3 because it is opened and closed by being guided by the guide grooves 4 and 5 of b. Further, the lower frame member 1b is provided with guide walls 7a, 7b for guiding the lower end of the net 2 and the lower end of the operating frame 3 along both front and rear sides thereof, and the rolling wheel 6 is formed in the guide groove 5 formed by them. The guide surfaces 7c are formed, and the pair of rolling wheels 6 are configured to roll on these guide surfaces 7c.

On the other hand, inside the upper frame member 1a, as clearly shown in FIGS. 2 and 3, an inner guide member 8 which is guided for vertical movement along the inner side surface of the upper frame member 1a is fitted. A protrusion 9 projecting from the upper end of the operating frame 3 is fitted into the slit 8a provided in the inner guide member 8 to guide the sliding. The inner guide member 8 is simply fitted in the upper frame member 1a, and therefore, is placed on the operating frame 3 and movable up and down in the upper frame member 1a. The member 1a may be fixed to the member 1a with screws or the like so that its position can be adjusted.

According to this structure, the length of the side frame member 1c is adjusted according to the vertical dimension of the building opening (the side frame member 1c
Even if the adjustment is performed by cutting or adjusting the connection position with the upper and lower frame members), the upper end of the operating frame 3 deeply enters the upper frame member 1a as shown in FIG. 2 or shallowly as shown in FIG. However, it does not hinder the function of the screen door. However, the distance between the upper frame member 1a and the lower frame member 1b can be adjusted within a range in which the operating frame 3 can be guided in the guide grooves 4 and 5 of the upper and lower frame members.

In order to prevent the net 2 from being bent by the action of wind pressure or the like, as shown in FIG. 5, the upper end and the lower end of the net 2 are directly engaged with a part of the net 2, respectively. A plurality of retainers 10 and 20 are engaged and fixed at appropriate intervals, and these retainers 10 and 20 are connected to the upper frame member 1 of the screen door frame 1.
a and a guide engaging groove provided in the lower frame member 1b are slidably engaged with each other, whereby the net 2 is held in an appropriate tension state.

The retainer 1 attached to the upper portion of the net 2
