BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding screen door which is used by being attached to a window or an entrance of a building, and more particularly to a folding screen door which opens and closes by accordion-type expansion and contraction of a net. is there.

[0002]

2. Description of the Related Art The inventor of the present invention has previously disclosed Japanese Utility Model Application No. 4-45820.
The foldable screen door was proposed by the number. This screen door can be opened and closed in a laterally open manner in a rectangular screen door frame composed of an upper frame member, a lower frame member, and right and left vertical frame members by applying a pleat to the accordion-type telescopic net. It is arranged, and one end of the net is attached to one vertical frame member, and an operation frame for opening and closing operation is attached to the other end of the net, and inside the frame members of the operation frame and the screen door frame, when opening and closing the net. A tension cord that regulates the inclination of the operation frame in the moving direction is stretched.

[0003] As a method of attaching such a screen door to a building opening such as a window or an entrance, there are a method of fixing upper and lower and left and right frame members of a screen door frame to a front surface of a building opening frame such as a sash with screws. There is a method of fixing the inner peripheral surface of the frame with screws. When the latter method is used, a screw is screwed into each frame member from the inside of the screen door frame, but inside the upper and lower horizontal frame members, guide members at the upper and lower ends of the operation frame are provided. The upper frame member is formed with a guide groove in which the upper frame member is fitted, a rail on which the rolling wheel at the lower end of the operation frame rolls, and the end of the net is attached to one vertical frame member. The lower frame member and one of the vertical frame members cannot be fixed to the inner peripheral surface of the building opening frame by directly screwing a screw from the inside of the screen door frame with the above-described guide groove, rail, net or the like as an obstacle. For this reason, these three frame members are
The fixing base member is configured to be detachably provided, and the base member is fixed to the building opening frame by screws, and then connected to the base member. It is conceivable to fix the frame member directly to the inner peripheral surface of the building opening frame with screws.

However, inside the vertical frame member, one or two tension cords pass through the space behind the inner wall where the screws are screwed, so that the screws are screwed through the space. When worn, the tension string comes into contact with the screw, and each time the net is opened and closed, the tension string rubs against the sharp thread tip of the screw. For this reason, it is easy to cause inconvenience such that the tension cord is worn to break the wire or the opening / closing operation is not smooth due to frictional resistance at the time of rubbing. In addition, when the inner wall is deformed due to the tightening of the screw, the direction of the deflector for winding the tension string attached in the insertion space of the tension string changes, and a support may be provided for guiding the tension string. Conceivable.

[0005]

The technical problem of the present invention is that the screw fixing the vertical frame member and the tension string do not come into contact with each other and rub against each other, and the vertical frame member is deformed by tightening the screw. An object of the present invention is to provide a foldable screen door that does not need to be performed.

[0006]

In order to solve the above problems, the present invention provides an accordion-type stretchable net by pleating an upper frame member, a lower frame member, and left and right vertical frame members. It is disposed in a rectangular screen frame so as to be openable and closable in a horizontal manner, and one end of the net is attached to one vertical frame member, and an operation frame for opening and closing is attached to the other end of the net. A tension cord that regulates the inclination of the operation frame when opening and closing the net is stretched inside each frame member of the frame and the screen door frame, and each frame member of the screen door frame is fixed to the building opening frame with screws. In the folding screen door, the vertical frame member of the two vertical frame members in the screen frame, which is located on the open end side of the net, is formed of a single H-shaped cross section having an intermediate wall in the middle. Formed on the vertical frame member A configuration in which a spacer having a hollow and smooth outer surface interposed between the middle wall and the building opening frame is attached through a space portion where the tension cord is inserted, and a fixing screw is screwed through the interior of the spacer. It is characterized by having done.

[0007]

In the foldable screen door having the above-mentioned structure, since the screw for fixing the vertical frame member is screwed through the hollow spacer, the tension cord inserted into the vertical frame member is directly applied to the screw. No contact. Even when the strap comes in contact with and rubs against the spacer, the outer surface of the spacer is formed smoothly, so that the opening and closing operation of the net is not performed due to the abrasion of the strap and resistance to rubbing. There is no trouble such as smoothing. Further, since the inner wall is supported from the inside by the spacer, there is no possibility that the inner wall is deformed by tightening the screws.

The operation frame 3 is made of a synthetic resin or a metal such as aluminum. The operation frame 3 has the pair of rollers 14 at its lower end and the anti-sway member 10 at both upper and lower ends. The anti-sway member 10 regulates the lateral vibration of the operation frame 3 during the opening and closing operation of the net 2, that is, the inclination in the lateral direction (the direction of the front and back of the screen door) and the rotation around the axis, and the opening and closing operation is smooth. Is to be performed. The portion of the operation frame 3 to which the net 2 is fixed is a concave groove-shaped net accommodating portion 3b, and when the screen door is opened to the maximum, the folded net 2 is connected to the net accommodating portion 3b and the vertical frame member 1d. The operation frame 3 is formed with a groove 28 in the vertical direction on both outer side surfaces of the operation frame 3 so that a hand can be used for opening / closing operation.

The end surface (front end surface) of the operation frame 3 opposite to the side on which the net 2 is attached is a ridge 3a, and when the net 2 is closed, the ridge 3a becomes a vertical frame. Folded edges 22b, 2 at the ends of the side walls 22, 22 in the member 1c

At the time of opening / closing operation of the net 2 by the operation frame 3, it is possible to prevent the operation frame 3 from tilting in the moving direction, thereby preventing the opening / closing operation from becoming unsmooth. A parallel movement mechanism is provided in order to perform an open / close operation. This parallel movement mechanism connects both ends of two tension cords 30a and 30b to the upper half and the lower half of the operation frame 3 from opposite directions, respectively, and places these tension cords in the screen door frame 1. It is stretched by appropriately wrapping it around a deflecting device such as a pulley or a fixed guide. Even when the user moves the upper and lower halves of the operation frame 3, the lower half of the operation frame 3 is moved through these tension cords. The same magnitude of force is applied to the part or upper half in the moving direction, whereby the attitude of the operation frame 3 is held vertically and the upper and lower ends can be moved horizontally. is there.

There are various ways of tensioning the tension string in the parallel moving mechanism, and any of the tensioning methods may be selected. In the illustrated embodiment, the following configuration is adopted. That is,
One end of two tension cords 30a, 30b is fixed to the upper half of the operation frame 3, and one of the tension cords 30a extends upward in the operation frame 3 and then swings upward. It is inserted into the stop member 10 and changes its direction in the horizontal direction, passes through the upper horizontal frame member 1a, is guided to one vertical frame member 1c, and is wound around the upper diverter 31 to be turned into the vertical frame member 1c. After being guided to the lower end of the lower diverter 32, the diverter 32 is horizontally diverted by the lower diverter 32, guided in the lower horizontal frame member 1 b to the opposite vertical frame member 1 d, and wound around the lower diverter 33. After turning upward, it is wrapped around the intermediate turning element 34 and turns sideways, penetrating the lower part of the net 2 horizontally, and
Is guided to the operation frame 3 from a direction opposite to the opposite end of the tension cord 30a fixed to the upper half of the operation frame 3, and is fixed to the lower half of the operation frame 3.

The other tension cord 30b extends from the upper half of the operation frame 3 in the opposite direction to the tension cord 30a and penetrates the net 2, and then reaches the vertical frame member 1d.
To the lower frame member 1b.
Is guided to the vertical frame member 1c on the opposite side, is wound around the deflecting element 32, and is folded back, thereby being opposite to the opposite end of the tension cord 30b fixed to the upper half of the operation frame 3. , Is guided into the operation frame 3, is inserted into the steady rest member 10 below the operation frame 3, turns upward, and is fixed to the lower half of the operation frame 3.

Thus, when the operation frame 3 is opened and closed, even if the user moves the upper frame or the lower half by holding the upper half or the lower half, the lower half of the operation frame 3 is passed through the tension cords 30a and 30b. Alternatively, since the same magnitude of force is applied to the upper half in the moving direction, the operation frame 3 moves horizontally at both upper and lower ends while reliably maintaining the vertical position. The net 2 can be opened and closed very stably by the synergistic effect with the anti-lateral shake effect. The ends of the tension cords 30a and 30b are all fixed to the operation frame 3 with nuts 36 and screws 37, and the fixing position can be adjusted along the longitudinal long groove 38.

When the screen door is used, the net 2 is bent by the action of wind pressure or the like to prevent the upper and lower ends from being disengaged from the upper frame member 1a and the lower frame member 1b to form a gap.
At each of the upper and lower ends of the net 2, at least one support member 40 which is directly fixed to the net 2 or locked by a cable is provided, and these support members 40 are formed by an upper frame member. The guide groove 1a and the guide groove 12 of the lower frame member 1b are movably engaged with each other.

In the screen door having the above structure, the frame members 1a to 1d of the screen door frame 1 are connected to a frame 5 such as a window or an entrance.
Is fixed to the inner surface of the building with screws 4, thereby being attached to the building opening frame 5. In this case, a hollow spacer 24 is attached to the vertical frame member 1c located on the open end side of the net 2, and the screw 4 is screwed through the inside of the spacer 24. Does not directly contact the tension string 30a and rub against each other. Further, even if the tension cord 30a comes into contact with and rubs against the spacer 24,
Since the outer surface is smoothly formed, there is no problem that the opening / closing operation is supported due to abrasion, disconnection, or frictional resistance when rubbing each other. In addition, the above spacer 2
Since the middle wall 23 is supported from the inside by the interposition of the screw 4, the middle wall 23 is not deformed by the tightening of the screw 4, so that the turning elements 31, 32 attached to the vertical frame member 1 c are not deformed. The direction is changed, and no support is provided for guiding the upholstery string 30a.

[0026]

As described in detail above, according to the screen door of the present invention, a hollow spacer is attached to the vertical frame member located on the open end side of the net, and the screw is screwed through the interior of the spacer. Since the screw and the tension string are brought into contact with each other, it is possible to reliably prevent the screw and the tension cord from coming into contact with each other and rub against each other, and also prevent the inner wall of the vertical frame member from being deformed by tightening the screw. it can.
