[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding screen door having a net folded in a bellows shape so as to be openable and closable in a screen frame. The present invention relates to an improvement in a mechanism for locking an operation frame for operation.

[0002]

2. Description of the Related Art As a screen door in which a net can be freely opened and closed,
2. Description of the Related Art Conventionally, a folding screen door, which is formed in a bellows-like shape and has a stretchable net that can be freely opened and closed within a screen frame,
It is well known.

In such a folding screen door, it is necessary to lock both ends of the net to a screen frame and an operation frame for opening / closing operation. For this purpose, a conventional structure is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 5-179875. As disclosed, a plate-shaped locking member (support member) is provided at the end of the net.
The locking member is inserted into a locking groove provided in a screen frame and an operation frame (slide bar) to be locked. However, since the above-mentioned conventional locking member is composed of a single plate, it is very troublesome to bond a coarse material such as a net to one surface with an adhesive, and the bonding strength is relatively low. Due to the small size, there is also a disadvantage that the net is easily peeled off when a tensile force acts on the net when opening and closing the net. In addition, when the bellows-like net opens and closes while expanding and contracting, the locking member swings in the locking groove and collides with the groove wall, so that there is a problem that noise is easily generated.

[0004]

SUMMARY OF THE INVENTION A main object of the present invention is to simply and firmly fix a locking member for locking the end to a screen frame or operation frame at an end of a net in a folding screen door. To be able to do it. Another object of the present invention is to prevent the locking member from colliding with the locking groove wall when opening and closing the net to generate noise.

[0005]

In order to solve the above problems, a folding screen door according to the present invention is provided on an end of a net folded in a bellows shape, and the end is provided on a screen frame or an operation frame for opening and closing operation. A locking member for locking is attached, and the locking member includes a pair of left and right holding portions made of a hard synthetic resin, and a bent portion made of a soft synthetic resin interconnecting the holding portions. At the position of the bent part, the locking member is bent into two parts, the end of the net is held between the two holding parts, and the two holding pieces are mutually connected via the net. Is fixed to the end of the net by bonding to the end of the net. According to a specific configuration of the present invention, a locking groove is formed in the screen door frame or the operation frame, and the locking member is inserted and locked in the locking groove. In the above case, it is desirable that the bent bent piece of the locking member also serves as a buffer member for buffering the locking member against the groove wall of the locking groove. According to a preferred configuration of the present invention, the bent part of the locking member is formed to be thinner than the pair of holding parts, and is provided at a position deviated to the outer surface side of the two holding parts. I have.

[0006]

The above-mentioned locking member is bent into two at the position of the soft bent part to hold the end of the net between the two hard holding parts and to bond these two holding parts to each other. Thus, since the fixing member is fixed to the end of the net, the locking member can be easily and firmly fixed to the net which is a coarse material. By inserting the locking member into the locking groove, the end of the net to which the locking member is fixed,
It is locked to the screen frame or operation frame. At the time of opening and closing the net, even if the locking member swings in the locking groove due to the expansion and contraction of the bellows-like net, the collision with the groove wall is avoided by the buffering action of the soft bending piece, There is no noise.
Further, since the bent portion piece of the locking member is formed to be thinner than the holding portion piece and is provided at a position deviated to the outer surface side of both the holding portion pieces, the locking member is bent into two. Sometimes, the bent piece is bent into a gently curved state, and can sufficiently fulfill the cushioning function.

[0007]

The embodiment shown in FIGS. 1 and 2 shows a case where the folding screen door of the present invention is configured as a horizontally opening screen door which can be attached to a sash in a building opening.
In the figure, reference numeral 1 denotes a screen frame having a rectangular shape, reference numeral 2 denotes a net attached to the door frame 1 so as to be openable and closable, and reference numeral 3 denotes an operation frame attached to an end of the net 2 for opening and closing operations.

The screen door frame 1 is formed by connecting the upper frame member 1a and the lower frame member 1b to the left and right side frame members 1c and 1d with screws by a screw. It can be fixed.

The net 2 is made to be able to expand and contract in a bellows-type by applying a large number of pleats, and is arranged in the screen door frame 1 so as to be openable and closable by expanding and contracting in the lateral direction.
Plate-shaped locking members 5 are respectively attached to the left and right end portions over substantially the entire length, and these locking members 5 are provided on one side frame member 1d of the screen door frame 1 and the operation frame 3, respectively. By being inserted and locked in the locking grooves 6, 7, both ends of the net 2 are locked to the side frame member 1 d and the operation frame 3, respectively. The upper and lower ends of the net 2 are respectively fitted into recesses of the upper frame member 1a and the lower frame member 1b of the screen door frame 1.

As shown in FIG. 3, the locking member 5 has a pair of left and right plate-like holding members 10 and 10 made of a hard synthetic resin, and connects the holding members 10 and 10 to each other. The bending member 11 is made of a soft synthetic resin and is formed by extruding them integrally. As shown in FIG. 4, the locking member 5 is divided into two at the position of the bending member 11. It bends so that the end of the net 2 is held between the two holding pieces 10, 10, and the two holding pieces 1 are inserted through the net 2.
The wires 0 and 10 are fixed to the end of the net 2 by bonding them to each other.

The conventional method of bonding the net 2 to one side of the locking member composed of a single plate by forming the locking member 5 to be freely bent as described above and sandwiching the locking member 5 at the end of the net 2 The fixing to the net 2 can be performed easily and firmly as compared with the case of FIG. The holding pieces 10 may be adhered by applying an adhesive, but the double-sided adhesive tapes 12 may be applied to the inner surfaces of the holding pieces 10.
Can be adhered and bonded with the adhesive tapes 12 and 12.

The bent piece 1 of the locking member 5
1 also includes a cushioning member for preventing the locking member 5 from swinging in the locking groove and colliding with the groove wall as the bellows-like net 2 opens and closes while expanding and contracting when the net 2 is opened and closed. It is also a thing. Therefore, in order to enhance the cushioning property, the bent piece 11 is desirably bent so as to be curved in an arc shape using elasticity without being bent sharply. In this case, as shown in the figure, the bent piece 11 is made thinner than the pair of holding pieces 10, 10 and the bent piece 11 is shifted to the outer surface 10 a side of the both holding pieces 10, 10. It is desirable to provide it, whereby it becomes easy to bend the bent piece 11 into a curved state, and its elasticity is increased to improve the cushioning function.

The operation frame 3 is made of a synthetic resin or a metal such as aluminum, and has a pair of wheels 1 at its lower end.
, And a pair of rails 15, 15 opposed to the lower frame member 1 b at intervals.
It is placed so that it can roll freely. In addition, anti-sway members 16 and 1 are provided at both upper and lower ends of the operation frame 3.
7 are provided, and these anti-sway members 16 and 17 are formed by slits 1 formed in the upper frame member 1a and the lower frame member 1b.
8 and 19, the horizontal swing of the operation frame 3 during the opening / 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), the rotation around the axis, and the like are regulated. The operation can be performed smoothly.

On the side surfaces of the operation frame 3 and the side frame member 1d on the net mounting side, projecting walls 20 and 21 having substantially the same length are respectively formed at positions opposite to each other with the net 2 interposed therebetween. When the screen door is opened to the maximum, the folded net 2 is accommodated in a state of being covered and hidden inside the overhanging walls 20 and 21.

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 to prevent the opening / closing operation from becoming unsmooth, and to maintain the posture of the operation frame 3 vertically and smoothly. A parallel movement mechanism is provided in order to perform an open / close operation. This parallel movement mechanism connects both ends of the two tension cords 23a and 23b between the upper right half and the lower left half and between the upper left half and the lower right half of the operation frame 3, respectively. , These straps, the screen door 1
It is stretched by appropriately winding it around a diverter 25 such as a pulley or a fixed guide. Even when the operation frame 3 is moved by holding the upper half or the lower half thereof, the operation frame 3 is moved through these tension cords. So that a force of the same magnitude is applied to the lower half or the upper half in the moving direction, whereby the posture of the operation frame 3 is held vertically and the upper and lower ends thereof can be horizontally moved. It was done. In addition, the said parallel movement mechanism
The configuration is not limited to the illustrated configuration, and any other configuration can be used.

In the above embodiment, both ends of the net 2 are locked by the locking members 5 to the side frame member 1d of the screen door frame 1 and the operation frame 3 respectively.
However, depending on the structure of the screen door, only one end of the net 2 is attached to the side frame member 1d or the operation frame 3 by the locking member 5, and the other end of the net 2 is directly or by other means. It may be attached to the other operation frame 3 or the side frame member 1d. Alternatively, the operation frame 3 is attached to each side end of the net 2 so that the net 2
In some cases, both ends or any one end of the net 2 can be connected to the operation frame 3 by the locking member 5. To stop.

In the above-described embodiment, the locking member 5 is loosely inserted into the locking grooves 6 and 7 provided in the side frame member 1d or the operation frame 3, thereby forming the grooves of the locking grooves 6 and 7. Although it is locked inside the edge, the locking member 5 can be
Alternatively, it can be fixed to the operation frame 3 with screws or the like. In addition,
It goes without saying that the above-mentioned folding screen door can be installed not only in a case where it is attached to an existing sash but also in an arbitrary mode such as being directly attached to an opening of a building.

[0018]

As described in detail above, according to the folding screen door of the present invention, the locking member for locking the end of the net to the screen frame or operation frame is a pair of left and right hard synthetic resin. And a bent portion made of a soft synthetic resin for interconnecting these sandwiched portions, which is bent into two at the position of the soft bent portion. ,
Since the ends of the net are clamped between the hard clamping parts and the two clamping parts are adhered to each other, they are fixed to the ends of the net. Even so, the locking member can be easily and firmly fixed. In addition, by making the bent bent piece function as a cushioning member, during opening and closing operation of the net, the locking member swings in the locking groove as the bellows-like net opens and closes while expanding and contracting. Thus, it is possible to reliably prevent an abnormal sound from colliding with the groove wall. Further, the bent portion of the locking member is made thinner than the pair of sandwiching portions, and the bent portion is provided at a position deviated to the outer surface side of both the sandwiching portions. The bent piece can be easily bent into a curved state, and as a result, the elasticity can be increased to provide a superior cushioning function.
