DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a housing 4 having both front and rear plates 1 and 1, an upper bridge plate 2, and a lower bridge plate 3 is opened at the front and rear. Therefore, the dashed line and the thickness are omitted) is prepared,
Two rows of front and rear guide rails 5 and 6 are formed on both side plates 1 and 1. The rear guide rails 6, 6 have a blade member extending / contracting device including the first blind device 10 and a second blind device.
The blade member expansion and contraction device including the blind device 12 is disposed in a vertical positional relationship. Front guide rails 5, 5
Is disposed with an insect net device 8 described later. The distance between the front rail 5 and the rear rail 6 is determined by any of a later-described blade member of the insect repelling net device 8, a later-described blade member of the first blind device 10, and a later-described blade member of the second blind device 12. The blades have a minimum length that does not interfere with each other in a contracted state with the blade member having a wide front and rear width. Further, the opening width of the guide rail (the inside of a recessed and returnable member described later) is such a width that a finger of an infant cannot easily enter, for example, 4
mm.

Insect netting device 8, first blind device 10
In each of the second blind device 12 and the second blind device 12, the cross-section in the width direction of each blade member is supported or integrated by the link 16 of the pantograph mechanism 14, and the interval between the respective blade members expands and contracts due to expansion and contraction of the pantograph mechanism, and the pantograph mechanism Are guided by the rails (described later), and only the form of the blade member is different. The applicant has already described the above-described configuration in the second embodiment (FIG. 1 (b), FIGS. 4 to 4) of the patent application “louver type blind” (reference number BLIND-1) filed on May 6, 1998. 9).

The blade member 18 of the insect net device 8 is constituted by an insect net member comprising a frame 20 forming a frame of the blade member and an insect net 22 stretched over the frame 20. The blade member 24 of the first blind device 10 is formed of a translucent blind member in which a surface of a plastic material such as polypropylene is processed into a ground glass surface. Blade member 2 of second blind device 12
Reference numeral 6 denotes an opaque blind member formed of a frame made of, for example, a plastic material or a metal material, and an opaque material such as a galvanized sheet stretched over the frame. A predetermined light reflection film such as a metal film that sufficiently reflects light is formed on the back surface of the blade member 26 of the second blind device by a predetermined means.

When the wing member 18 is completely extended, the upper end of the uppermost wing member 18 is positioned on the upper bridge plate 2.
So that the lower end of the lowermost blade member 18 is in contact with the lower bridge plate 3 and the overlapping portions of the adjacent blade members 18 are in contact with each other, and the outer link 31 constituting the pantograph mechanism is a side plate. 1 so that the housing 4
The length relationship is defined. The thickness of the outer link 31 constituting the pantograph mechanism is sufficiently small to prevent mosquito invasion. Therefore, when the wing member 18 is completely extended, mosquitoes are prevented from entering through the inside of the housing 4.

The first blind device 10 and the second blind device 12 are completely contracted in a state where one of them is brought close to the upper bridge 2 or the lower bridge 3, and the other is completely blind. When extended, the upper end of the uppermost blade member and the lower end of the lowermost blade member of the other blind device are connected to the lowermost blade member or the uppermost blade member of one blind device,
And abuts on the lower bridge 3 or the upper bridge 2 of the housing 4,
The length relationship with the housing 4 is determined so that the overlapping portions of the adjacent blade members are in contact with each other and the outer link 31 constituting the pantograph mechanism is in contact with the side plate 1. Further, the thickness of the outer link 31 constituting the pantograph mechanism is small. Therefore, when one blind device is completely contracted and the other blind device is fully extended, the ingress and egress of air are sufficiently prevented.

Next, at the fulcrum of the center fulcrum row of the three fulcrum rows of the pantograph mechanism 14 of each apparatus, a fulcrum is extended outward. 6 is fitted.

Recessed members 34 such as rubber and sponge are fixed to the guide surfaces of the guide rails 5 and 6, and both side surfaces of the extended portion 32 are recessed and returned. Is pressed against.

Accordingly, by sliding the extended portion 32 along the guide rail against the frictional force from the concave and returnable member 34, each device 8, 10, 12 can be moved to an arbitrary position. The device can be moved and the distance between the blade members can be expanded and contracted, and each device maintains the state after the movement and the expansion and contraction at an arbitrary position.

The housing 1 is constructed as described above, and the insect repelling net device 8 side faces the front side (outward), and the housing 1 is attached to each of two rails provided in the horizontal direction. A glass plate sash of half the size in the left-right direction of the part is arranged, and the glass plate sash can be moved along the rail, so that the maximum opening is obtained when two glass plate sashes are superimposed. ) Can be mounted without any gap inside or outside the entire surface of the mounting opening. Since the width of the housing 1 in the front-rear direction is equivalent to two blade member expansion / contraction devices,
The case 1 is narrower than the case, and therefore, the case 1 is prevented from largely protruding inward or outward.

In the case of a season such as summer when insects such as mosquitoes enter the room, the insect net member 18 of the insect net device 8 is completely extended, and the overlapping portions of the adjacent blade members abut each other. Let it. Then, there is no gap in the insect repellent net device 8 for insects such as mosquitoes, so that insects such as mosquitoes cannot enter. If the blind device is not used in this state, the first blind device and the second blind device are completely contracted, and the glass window is opened and the two glass plate sashes are overlapped. Are opened, but insects such as mosquitoes do not invade due to the insect repellent net 8.

Next, when it is desired to avoid see-through and allow a certain amount of light and wind to enter the room, the translucent blind member 24 of the first blind device is extended by a desired amount to be in the louver state. The opaque blind member 26 of the blind device is contracted. The first blind device 1
When it is desired to prevent the generation of a gap between the zero and the second blind device 12, the second blind device is extended by the gap. Thus, even if the wind is a little strong, the wind and a predetermined amount of light can be received in the room, and the see-through of the room can be prevented.

Next, when it is desired to blow a predetermined amount of wind but the room becomes brighter at night or the like and it is not desired to transmit the light inside the room to the outside, the second blind device is extended by a predetermined amount, Therefore, the first blind device is contracted. As a result, the light in the room does not escape to the outside and the light is sufficiently reflected into the room by the light reflecting film on the back surface of the blade member 26, so that the light in the room can be efficiently used and the predetermined wind can be received in the room. Can be.

When it is desired to eliminate the ventilation, the window may be closed, but the first blind device or the second blind device 12 may be completely extended. That is, also in this case, the blade members come into contact with each other, so that there is no gap for the air to flow in and out, and the ventilation is blocked.

Next, in a season such as winter when insects such as mosquitoes do not enter the room, all the insect repelling members 18 of the insect repelling device 8 are moved upward or downward to contract. When the blind is not used, both the first blind device 10 and the second blind device 12 are contracted.
Accordingly, light that is not blocked by the insect net device 8, the first blind device 10, and the second blind device 12 and that passes through the sliding glass window can be introduced into the room.

When the insect net device 8, the first blind device 10 and the second blind device 12 are operated, the outer link of the pantograph mechanism 14 is connected to the side plate 1 of the housing.
Therefore, since the rhombic hole 35 of the pantograph mechanism 14 faces the guide rail 5 or 6 and the side plate 1 (the mounting plate for the guide rail), the fingers of the slits 5 and 6 of the guide rail do not enter. Because of the width, the finger can be inserted only into the rhombus hole 35 of the pantograph mechanism 14 from the blade member side. However, since the inserted finger cannot advance beyond the side plate 1, the fingertip should have a diamond shape. Even if the blade member expands and contracts while located in the hole, the fingertip can easily escape from the diamond-shaped hole, and the finger base and the palm are first pinched between the blade members, so that the finger is pinched between the links of the pantograph mechanism. Injury is greatly prevented.

In the above embodiment, the first and second blind devices 10 and 12 have one of them completely contracted,
Although it is assumed that the blade members can be extended until they come into contact with each other, when not used as a ventilation opening / closing device, one is completely contracted while the other is extended to the maximum, and the blade members are separated by a predetermined amount. It may be. Thus, when only one of the blind devices is used, no gap is formed above or below the blind device.

In the above embodiment, the insect repelling net is provided, but the insect repelling net is not necessarily required. Also, instead of the insect net device, an insect net may be directly spread over the entire surface of the housing 1.

In the above-described embodiment, the frame 4 is attached to the entire surface of the opening for attaching the sliding glass window. You may make it attach to a half part.
Further, the frame 4 may be directly attached to the entire surface of the opening having no ventilation opening / closing means such as a sliding glass window (that is, even in this case, the ventilation opening / closing is performed by completely extending the first blind device or the second blind device). Means).

In the above embodiment, the front and / or rear positions of the insect repelling device 8 at the upper or lower part of the housing 4 are
A blindfold member of the contracted insect net device may be provided. Similarly, the blindfold members of the contracted first blind device and second blind device are located at the front and / or rear positions of the first blind device and the second blind device in the upper and lower portions of the housing 4. May be provided.

In the above embodiment, the guide rails 5, 6
By pressing both sides of the extended portion 32 of the support shaft against a concave and returnable member 34 such as rubber or sponge fixed to the guide surface of the above, the movement and expansion and contraction of each device and the subsequent state thereof are maintained. However, along the guide rail extension direction (vertical direction) on the guide surface of the guide rail,
A plurality of retractable clicks are provided, and the clicks can be retracted by a predetermined force. When the force is removed, the clicks return to their original positions. By moving over with a predetermined force, the extension portion 32 may be moved along the guide rail and the position after the movement may be maintained. Further, the support shaft of the uppermost or lowermost blade member of the insect repellent net device is rotatably fixed to the upper or lower part of the side plates 1 and 1, and the position of the blade member of the insect repellent net device after expansion and contraction is maintained. (See, for example, the applicant has already filed a patent application “Louvre type blind” on May 6, 1998 (reference number BLIND-
[0036] to [0039] disclosed in 1)
(Mechanism of FIG. 7). Similarly, the support shaft of the uppermost blade member of the first blind device is rotatably fixed to the upper portion of the side plates 1 and 1, and is attached to the first blind device itself. The position of the blade member after expansion and contraction may be maintained by means (not shown) separately provided, and the pivot of the lowermost blade member of the second blind device can be rotated to the lower part of the side plates 1 and 1. , And the position of the blade member after expansion and contraction may be maintained by means (not shown) separately provided in the second blind device itself (the same mechanism is also attached to the uppermost blade member).

In the above-described embodiment, the pantograph mechanism is provided at both ends of the blade member. However, the pantograph mechanism may be disposed at an intermediate portion of the blade member, or may be provided in any number. Further, as shown in FIG.
A pantograph mechanism in which every other link 120 and 122 is arranged in one position (this is a pantograph mechanism composed of two rows of links separated from each other and connected at both fulcrums). (This configuration has already been disclosed by the applicant of the present invention on May 6, 1998 as a patent application “louver type blind” (reference number BLIND-
1) [0049] (disclosed in FIG. 9).
If the pantograph mechanism does not exist at the end of the blade member, a shaft that fits on the guide rail is attached to the blade member. In this case, the position of the shaft may be any position in the width direction of the blade member. If there is a portion where the blade member does not face the opening of the guide rail, brush bristles, etc.
An upright and flexible forest fibrous member may be provided at the opening of the guide rail so as to be movable by pushing the forest fibrous member of the extension member 32 apart. This prevents invasion of insects such as mosquitoes.

In the above embodiment, a combination of the translucent blind device and the opaque blind device is used. However, various other combinations can be considered. For example, the blade member is made transparent, and a ventilation opening / closing device using the transparent blade member (when the interval between the transparent blade members is extended and adjacent blade members are brought into contact with each other, the ventilation is shut off, the interval is reduced, and the blade member is reduced. Separating them allows ventilation.)
And a translucent or opaque blind device. Also, a combination of the same two blind devices in different directions in the above embodiment may be used (in the above embodiment, the blind blade members 24 and 26 are used).
Is a direction in which the sun is lowered outward, but in the case of a blind device in which the sun rises outward, sunlight can enter the room from between the blade members. In this case, when both blind devices are used at the same time, each blind device only needs to be about half as long, and the movement and extension / contraction operation of the blind device need only be operated by half, so that the blind device is operated with less force. Will be able to do it. In general, if two blind devices are arranged on the same guide rail and extended and used simultaneously,
Since the length of each blind device can be reduced by about half, each device can be moved and expanded and contracted with less force, which is also included in the scope of the present invention. is there.

Further, a combination of three or more devices may be used. For example, three devices such as a translucent blind device, an opaque blind device, and a ventilation opening / closing device using a transparent blade member may be opposed in the expansion and contraction direction, and two translucent blind devices having different blade member directions and different directions. A total of four devices of two opaque blind devices may be simultaneously opposed in the direction of expansion and contraction.

Next, in the above-described embodiment, the blade member extending / contracting device in which the cross section in the width direction of each blade member is supported or integrated with the link of the pantograph mechanism and the interval between the blade members expands / contracts due to the expansion / contraction of the pantograph mechanism. However, as shown in FIG. 3, for example, each blade member (slat)
However, at least a pair of pantograph mechanisms are pivotally supported at different positions in the longitudinal direction (both ends in FIG. 3) and different positions in the width direction (indicated by s in FIG. 3). The present invention is also applicable to a blade member expansion / contraction device (this configuration has already been filed by the present applicant on May 6, 1998 as a patent application “louver type blind” (reference number BLIND-
1) Third Embodiment (FIG. 1C, FIGS. 10 to 1)
2)). The shape of the blade member (slat) can be variously changed. In this configuration,
A shaft is provided at the center of the end surface of the blade member, and the shaft is fitted to the guide rail.
