A roll screen door as disclosed in Japanese Patent No. 44380/44 has been proposed. The roll screen door will be described with reference to FIGS.

[0003] Inside a window frame 4 composed of an upper frame 1, a lower frame 2, and left and right vertical frames 3a and 3b, a pair of inner and outer window shojis 5a and 5b are provided.
b is built in the pull-down formula. Each window shoji 5a, 5
b are glass panels 10a and 10b, respectively, by upper frames 6a and 6b and lower frames 7a and 7b extending in the horizontal direction, and door frames 8a and 8b and combining frames 9a and 9b extending in the vertical direction.
0b.

[0004] Cases 11a and 11b are provided on the inner surfaces of the vertical frames 3a and 3b, respectively, at portions facing the mating frames 9a and 9b, respectively. Each case 11a, 11
b, roaming drums 12a and 12b are provided rotatably about vertical axes 13a and 13b, respectively, and nets 14a and 1b are respectively provided on the winding drums 12a and 12b.
4b supports one end in the length direction. Also, each net 14a,
14b, drawer frames 15a, 15b
I support. Each winding drum 12a, 12b
A torsion coil spring (not shown) is provided between the winding drums 12a and 12b.
a, 14b.

[0005] A through hole 16b is formed in the outdoor side (upper side in Fig. 2) of the door frame 8b constituting the window shoji 5b on the indoor side (lower side in Fig. 2). 1
7b is allowed to enter and exit from the outdoor side surface. That is,
The drawer piece 17b rotates or moves in parallel in the indoor and outdoor directions based on the operation of the knob 18b provided on the indoor side surface of the door frame 8b, and the hook portion 19b formed on the outdoor side edge is Allow to enter and exit from the outdoor side.

When closing the window shoji 5b on the indoor side,
Drawer frame 15b facing the outdoor side surface of door frame 8b
A hook portion 20b is formed on the indoor side edge portion of the hook portion 20b so as to be freely engageable with the hook portion 19b. Further, a suspending roller 46 that rotates about a horizontal axis 45 is provided at the upper end of the drawer frame 15b, and the suspending roller 46 is mounted on the upper surface of the guide rail 47 on the lower surface of the upper frame 1. I have. Therefore, the weight of the drawer frame 15b is supported by the guide rail 47.

On the other hand, the window shoji 5a on the outdoor side (upper side in FIG. 2)
A through hole 16a is formed in the indoor side surface (lower side surface in FIG. 2) of the door frame 8a, and a pull-out piece 17a is provided on the indoor side surface of the door frame 8a through the through hole 16a. Based on the above operation, the user can freely enter and exit from the indoor side surface. Further, when the window shoji 5a on the indoor side is closed,
Drawer frame 15a facing the indoor side surface of the door frame 8a
A hook portion 20a is formed at the outdoor side edge of the hook portion 20a so as to be freely engageable with the hook portion 19a having the same configuration as the hook portion 19b.

In a sliding window provided with a roll-type screen as described above, when the screen is required, such as in summer,
Based on the operation of the knobs 18a and 18b, the hook portions 19a and 19b of the drawer pieces 17a and 17b are made to protrude from the indoor side surface of the door frame 8a and the outdoor surface of the door frame 8b.

In this manner, when the window shoji 5a on the outdoor side is moved in the opening direction (rightward in FIG. 2) in a state where the hooks 19a and 19b are projected, the hooks 19a
Engages with the hook 20a of the drawer frame 15a, and pulls the drawer frame 15a with the movement of the window shoji 5a. Then, the winding drum 12 supported by the vertical frame 3a
a is rotated against the elasticity of the torsion coil spring, and the net 14a wound around the winding drum 12a is pulled out. The net 14a is stretched between the vertical frame 3a and the door frame 8a. I do.

When the window sash 5a is moved in the closing direction, the winding drum 12a is rotated by the elastic force of the torsion coil spring and winds the net 14a. Indoor window shoji 5
b, the net 14b is similarly connected to the vertical frame 3b.
And the door frame 8b.

When the screen is not required in winter or when objects and people enter and exit through the window and the screen is obstructed, the knobs 18a and 18b are operated to pull out the drawer pieces. The hooks 19a, 19b of 17a, 17b
Retract from the indoor side surface of the door frame 8a and the outdoor surface of the door frame 8b. As a result, each hook 19a, 19b
And the hooks 20a and 20b no longer engage with each other.
The window sashes 5a and 5b can be opened without pulling out the windows 4a and 14b.

[0012]

The roll type screen door constructed and operated as described above is different from a normal screen door in which a net is stretched inside the upper, lower, left and right frames.
a and 14b are simply pulled in the longitudinal direction based on the elasticity of the torsion coil springs attached to the winding drums 12a and 12b. Further, in order to prevent the force required to open the window shojis 5a and 5b from becoming unnecessarily large, the mesh 14
a, 14b is subjected to excessive pulling force, and this net 1
In order to prevent the torsions 4a and 14b from being broken at an early stage, the elasticity of the torsion coil spring cannot be so large. Therefore, the extension force of the nets 14a and 14b when the screen is used is not so large.

Therefore, when the screen door is used, the screens 14a, 14b
When the wind blows toward the nets, the nets 14a and 14b fluctuate even if the wind is a little wind, and the nets 14a and 14b
A gap is formed between the upper and lower edges of the upper frame 4b and the lower surface of the upper frame 1 and the upper surface of the lower frame 2 to allow insects to enter.

In the case of a roll screen door which is constituted by a winding drum which rotates around a horizontal axis and moves the screen vertically, the left and right edges of the screen door are guided by a pair of right and left vertical frames, as described above. A structure for preventing the fluctuation is realized. However, if such a structure for a vertical frame is applied to the lower frame as it is, dust tends to collect in the guide groove portion that guides the lower edge of the net, and if the dust accumulates, the net cannot be pulled out. I will. The roll screen door of the present invention
It was devised in view of such circumstances.

[0015]

The roll type screen door of the present invention comprises a window frame, a window shoji moving horizontally along the window frame, and a window frame, like the conventional roll type screen door. A take-up drum that is provided inside a vertical frame and rotates around a vertical axis, a net whose one end in the longitudinal direction is supported on the outer peripheral surface of the take-up drum, and a drawer frame that is supported at the other end of the net And a drawer piece that is provided on the door frame of the window shoji and moves in the opening direction of the window shoji and engages with the drawer frame and the winding drum. A spring for applying a rotational force.

Further, in the roll type screen door of the present invention,
On the upper surface of the lower frame constituting the window frame, there is a vertical wall portion that connects the lower portion on the outdoor side and the higher portion on the indoor side, and a part of the lower portion, which is separated from the vertical wall portion. , A brush formed by bundling a number of flexible wires is implanted, and the lower edge of the mesh penetrates between the vertical wall and the brush with the opening of the window shoji. It is characterized by being free.

[0017]

When using the roll screen door of the present invention constructed as described above, the lower edge of the net pulled out from the winding drum with the opening of the window shoji is formed by the vertical wall on the upper surface of the lower frame. Enter between the part and the brush. The distance between the vertical wall and the brush is small, and the lower edge of the net that has entered between the vertical wall and the brush does not easily fall out from between the vertical wall and the brush.
As a result, a gap that allows the insects to enter is not easily formed. In addition, dust does not easily accumulate in the structure for preventing the lower edge of the net from coming off.

[0018]

1 to 11 show an embodiment of the present invention.
For example, when the window 14b on the indoor side is opened, the net 14b is divided on the left and right by the door frame 8b and the vertical frame 3b constituting the window shoji 5b, and the upper frame 1 and the lower frame 2 vertically separate. It has a length dimension L and a height (width) dimension H enough to cover the opening to be partitioned.

The length direction of this net 14b (FIGS. 2, 9, 10)
At left and right ends of the cylindrical portions 21 and 21 formed as shown in detail in FIG. 11, rods 22 and 22 having an outer diameter of about 1 to 2 mm, such as a thick piano wire, 14b is inserted over the entire width (total height).

Further, on the outer peripheral surface of the winding drum 12b,
A recess 23 having a depth slightly larger than the outer diameter of the bar 22 is formed. When the end of the net 14b is connected and fixed to the outer peripheral surface of the winding drum 12b,
With the cylindrical portion 21 positioned at one corner of the concave portion 23, a cover member 24 is placed over the concave portion 23, and a fixing screw 25 inserted through the through hole of the lid member 24 is screwed into a screw hole formed in the winding drum 12 b. 26 is screwed tight.

On the other hand, the inside of the bent portion of the drawer frame 15b, which has a substantially L-shaped cross section, has a width dimension and a depth dimension capable of accommodating the cylindrical portion 21 into which the bar member 22 is inserted. A groove-shaped recess 27 is formed. Bar 22
When the end of the net 14b having the tubular portion 21 through which the wire is inserted is supported by the drawer frame 15b as described above,
1 is inserted into the recess 27, and the curved portion 2 of the lid 28 is
9 is fitted around the edge of the drawer frame 15b, and the opening of the recess 27 is covered by the holding portion 30 of the lid member 28. Then, the lid member 28 is attached to the drawer frame 15b.
Is fixed by a fixing screw 31. The upper and lower ends of the net 14b and the bar 22 are slightly protruded from the upper and lower ends of the drawer frame 15b, and the protrusions are connected to brushes 36 and 39, which will be described later, and the vertical wall portion 34 and the hanging plate 43. You can freely enter between.

As described above, the net 14b whose both ends are supported by the take-up drum 12b and the drawer frame 15b is incorporated into a sliding window as shown in FIGS. Configure. As shown in FIGS. 1 and 2, the operation of the roll-type screen door in which the net 14b supporting the take-up drum 12b and the draw-out frame 15b at both ends is incorporated in a sliding window is as described above. , Overlapping description will be omitted.

In particular, in the case of the roll type screen door of the present invention, the window frame 4
On the upper surface of the lower frame 2 that constitutes a vertical wall portion 34 that connects the low portion 32 on the outdoor side and the high portion 33 on the indoor side, there is a part of the low portion 32, A brush 36 formed by bundling a large number of flexible wires 35 is planted at a portion separated from the brush.

The brushes 36 are provided at predetermined intervals (for example, 300 mm) on the upper surface of the lower frame 2 as shown in the X section of FIG. Each of the brushes 36 is formed by injection-molding a synthetic resin such as nylon to form the mounting block 3 as shown in FIG.
The bases of the wires 35, 35 also made of an elastic synthetic resin or the like are pushed into the mounting holes 38, 38 of the seventh.

The brush 36 thus manufactured is engaged with the groove on the upper surface of the lower frame 2 and fixed with an adhesive or the like, as shown in FIGS. Then, the window shoji 5b is opened with the brush 36 fixed to the upper surface of the lower frame 2 in this manner, and the net 1
When the wire 4b is pulled out, the lower edge of the net 14b enters between the vertical wall portion 34 and the brush 36. Since the space between the vertical wall portion 34 and the brush 36 is small, the lower edge of the mesh 14b that has entered the space between the vertical wall portion 34 and the brush 36
You won't get out of between easily.

As a result, even when a little wind is blowing, a gap is formed between the lower end edge of the net 14b and the upper surface of the lower frame 2 to allow insects to enter. or,
If a strong wind blows or a part of a person or an object pushes the net 14b, the lower end edge of the net 14b is
Even if the brush comes out of the gap between the
b is wound on the winding drum 12b, so that the net 14
b can be returned to the original state. And then the network 14b
Is pulled out, the lower edge of the net 14b enters between the vertical wall portion 34 and the brush 36.

Since there is no possibility that dust will accumulate on the lower surface of the upper frame 1, the structure for preventing a gap from being formed between the lower surface of the upper frame 1 and the upper edge of the net 14b has a groove shape. For example, a conventionally known structure such as providing a guide rail may be used. However, in the case of the illustrated embodiment, a structure for preventing the mesh 14b from falling off by the brush 39 is also provided on the lower surface of the upper frame 1.

That is, the mounting block 40 as shown in FIG.
The brush 39 constituted by pushing the base ends of the wires 44, 44 in a bundled state into the mounting holes 41, 41 is inserted into the mounting holes 41, 41, for example, at the position Y in FIG. 8, as shown in FIGS. To
It is fixed to the lower surface of the upper frame 1 by screws 42. And
On the lower surface of the upper frame 1, near the brush 39,
The hanging plate 43 is fixed. The hanging plate 43 can be provided over the entire length of the upper frame 1. In this case, the mounting block 40 is fixed by cutting off a part of the hanging plate 43.

When the network 14b is pulled out, this network 1
The upper edge of 4b enters between the hanging plate 43 and the brush 39 to prevent a gap from being formed between the upper edge and the lower surface of the upper frame 1 by a little wind.

Although the above description has been made with respect to the screen door which is moved in and out with the opening and closing of the window shoji 5b on the indoor side, the screen door which is moved in and out with the opening and closing of the window shoji 5a on the outdoor side is described. The case is similarly configured.

[0031]

[Effects of the Invention] The roll screen door of the present invention is constructed and operated as described above, so that the lower edge of the net and the lower frame upper surface are blown by the wind without complicating the cleaning of the lower frame upper surface. It is possible to prevent the formation of gaps that allow insects to enter.
