As in the screen device shown in FIG. 21, an upper rail (3) can be provided at the upper end of the screen mounting frame (1), and stable sliding movement of the screen mounting frame (1) can be realized. (2) Opening and closing can be made smooth.

Further, in the screen device shown in FIGS. 23 and 24 (for example, JP-A-2000-145314), the slide guide frame (5) in the screen device shown in FIG. The slide guide frame (5) is replaced with a rigid guide unit (6) that is formed continuously with a rigid unit (6).

As shown in FIG. 24, the rigid unit (6) can be provided with a pair of side walls (6a) arranged opposite to each other and a bridging portion (6b) connecting them. As shown in FIG. 23, the side wall (6a) has a projection (7) projecting outward at one end thereof, and a through hole (8) with which the projection (7) can engage at the other end. Can be prepared,
Between the adjacent rigid units (6), the projections (7) are fitted into the through holes (8) from the back side of the side wall (6a), so that a plurality of rigid units (6) are continuously provided, and a slide guide frame is provided. The part (5) can be formed.

[0012]

However, the above-mentioned screen device proposed and provided by the applicant of the present application must be improved in order to further improve its performance and make it more versatile. Subsequent considerations have clarified that there are several issues that need to be addressed.

One of them is a sealing panel (4) and a slide guide frame (5), which are provided inside an upper rail (3), and are arranged at positions higher than the upper edge of the screen (2). It is about the mounting material.

The sealing panel (4) is, as described above,
Due to its own weight, the upper end of the screen (2) is abutted. However, since the screen (2) is opened and closed laterally, the sealing panel (4) is arranged in the longitudinal direction of the upper rail (3). It will be installed over the entire length or almost the entire length. Therefore, the sealing panel (4)
When the screen (2) is opened, the ceiling panel (4) is bent by its own weight depending on the size of the opened portion, and is exposed downward from the upper rail (3),
Not only does the appearance deteriorate, but it also hinders the sliding movement of the screen mounting frame (1), hindering a smooth opening and closing operation of the screen (2). In order to prevent bending, for example, a support portion which does not hinder the sliding movement of the screen mounting frame portion (1) is protruded inward at the lower edge of the upper rail (3), and the ceiling panel (4) is provided. However, the formation of the support portion leads to an increase in the width of the upper rail (3), and the support portion restricts the mounting space of the upper rail (3). The support of the sealing panel (4) is not sufficient.

For this reason, the sealing panel (4) is detached from the supporting portion by the positive pressure when the wind blows or the like, falls downward from the upper rail (3), and is lowered by the negative pressure. Floating upward inside, screen (2)
From the upper edge of the seal, and the original improvement of the sealing performance cannot be achieved.

In the screen device shown in FIG. 22, the slide guide frame portion (5) has flexibility and elasticity, so that when the screen (2) is closed, the slide guide frame portion (5) is pulled out from the inside of the screen mounting frame portion (1). Becomes longer. Therefore, vertical bending occurs at a portion where the linearity should be maintained, and this bending hinders the sliding movement of the screen mounting frame (1) and hinders the smooth opening / closing operation of the screen (2).

Also, in the case of the slide guide frame portion (5), the slide guide frame portion (5) swings up and down inside the upper rail (3) due to positive pressure or negative pressure such as when wind blows, and is displaced from a predetermined position. There is.

In the screen device shown in FIGS. 23 and 24, as described above, the slide guide frame (5) is
2 is easier to maintain linearity than the slide guide frame (5) in the screen device shown in FIG. As a result, the dimensions change, the slide guide frame (5) is deformed, and the linearity cannot be maintained. As a result, the sliding movement of the screen mounting frame (1) and the screen (2)
Hinders the smooth opening and closing operations of

The above problems are caused by an increase in the size of the screen device,
That is, the longer the width is, the more obvious it becomes, and the solution is urgently needed.

The invention of this application has been made in view of the circumstances described above, and a horizontal member disposed at a position equal to or higher than the upper edge of the screen may be bent or deformed. Can not maintain the linearity, can prevent the smooth opening and closing operation of the screen is obstructed, and the horizontal member is displaced from the predetermined position due to positive pressure or negative pressure such as when wind blows, It is an object of the present invention to provide a screen device that can prevent the screen device from falling.

[0034]

FIG. 1 is a longitudinal sectional view showing one embodiment of the vicinity of an upper rail in a screen device of the present invention.

The screen device according to the invention of this application follows the screen device proposed and provided so far shown in FIGS. 21 to 23 described above.

That is, like the screen device shown in FIGS. 21 to 23, the screen device of the invention of this application has a pair of screen mounting frames which are arranged to face each other in the horizontal direction and at least one of which is slidable. Department (1)
Between (1), the screen (2) is arranged so as to be contractable and expandable by pleating or the like, so that the screen (2) can be opened and closed horizontally.

The screen device according to the invention of the present application is provided with an upper rail (3) for guiding the sliding movement of the screen mounting frame (1) at its upper end, and as shown in FIG. A horizontal member (11) is provided inside the rail (3) at a position equal to or higher than the upper edge of the screen (2). This horizontal member (11) is shown in FIG.
In the screen device shown in (1), the sealing panel (4)
In the screen device shown in FIGS. 22 and 23, it corresponds to the slide guide frame (5).

The screen device of the invention of this application has a support portion (12a) that protrudes toward the inside of the lower end of the upper rail (3) and can support one side of the horizontal member (11). The cantilever (12) is shown in FIGS.
3 are disposed on both sides (3a) (3a) of the upper rail (3) with the sliding position of the screen mounting frame (1) shown in FIG.

The cantilever (12) can be, for example, in the form of small pieces, and as shown in the back view near the upper rail (3) in FIG. Can be installed side by side. The disposition portion may be only a part of the entire length of the upper rail (3) or a portion where the horizontal member (11) is easily bent or deformed. Further, as shown in FIGS. 1 and 2, the cantilever (12) can be arranged to face both sides (3a) (3a) of the upper rail (3).

The support (12a) of the cantilever (12)
It is not limited to the horizontal shape as shown in FIG.
The overhanging end can be bent upward as shown in FIG. By this bent portion (13), the horizontal member (1)
1) One side portion is supported at a position slightly higher than the support portion (12a), making the horizontal member (11) more invisible, and the horizontal member (11) is shown in FIGS. 23 and 24. In the case of the slide guide frame (5) formed by connecting the rigid units (6) as shown in the drawing, the left and right displacement can be suppressed, and the slide guide frame (5) from the support (12a) can be suppressed.
This is effective in preventing derailment of the vehicle. The horizontal member (11)
In the case of the sealing panel (4) shown in FIG. 21, one side of the horizontal supporting portion (12a) as shown in FIG. 1 can be sufficiently supported.

Both sides (3a) of the upper rail (3) (3a)
The mounting height of the cantilever (12) to the support (12
There is no particular limitation as long as a) protrudes toward the inside of the lower end of the upper rail (3), and as shown in FIG. 4 including the lowermost end of the side portion (3a) as shown in FIGS. Alternatively, it may be located slightly above the lowermost end of the side portion (3a). In the case of mounting the cantilever (12) as shown in FIG. 4, the lower edges of both sides (3a) and (3a) of the upper rail (3) are supported by the support (12a) of the cantilever (12). Since it is located lower than that, not only the horizontal member (11) but also the cantilever (12) itself becomes difficult to see, and the external appearance is further improved.

Further, as the cantilever (12), a beam corresponding to the type of the horizontal member (11) can be adopted.

For example, when the horizontal member (11) is the slide guide frame (5) having flexibility and elasticity in the screen device shown in FIG. 22, the bending that easily occurs in the slide guide frame (5) is as follows. As described above, since the direction is both up and down, as shown in FIG.
The slide guide frame (5) can be supported by sandwiching one side of the slide guide frame (5).
Considering the degree of flexing up and down, two
Can be juxtaposed. The two cantilevers (12) and (12) vertically arranged in parallel can adopt the same configuration, and as shown in FIG. 5, cantilever (12).
Upper cantilever (12) to facilitate mounting
With respect to (1), an upright portion (12b) may be provided, and a support portion (12a) may be provided and integrated at the lower end thereof.

By vertically arranging the two cantilever beams (12) vertically at a predetermined distance in this manner, the downward bending of the slide guide frame (5) is prevented by the lower cantilever beam (12).
Of the upper cantilever (12) is prevented by the support portion (12a) of the upper cantilever (12). Also, the upper and lower cantilever beams (12) (upward and downward) that the slide guide frame (5) swings up and down inside the upper rail (3) due to positive pressure or negative pressure such as when wind blows. 12) is prevented by the support portions (12a) and (12a).

The sandwiching support of the horizontal member (11) by the two cantilever beams (12) vertically arranged at predetermined intervals as described above is applied to the sealing panel (4) in the screen device shown in FIG. Is also effective. That is, the ceiling panel (4) rises inside the upper rail (3) due to the negative pressure when the wind blows, and comes off the upper end edge of the screen (2) because of the support of the upper cantilever (12). Part (12a).

The horizontal member (11) is the same as that shown in FIGS.
Rigid unit (6) in the screen device shown in FIG.
In the case of the slide guide frame portion (5) formed by the continuous arrangement of the above, a cantilever (12) having a substantially L-shaped cross section as shown in FIG. That is, as in the case of the upper cantilever (12) shown in FIG. 5, an upright portion (12b) is provided, and a support portion (12a) is provided at the lower end thereof to form an integrated cantilever (12). Can be.

As described above, when supporting one side of the slide guide frame (5) formed by the continuous connection of the rigid units (6), it is folded upward at the projecting end of the support (12a). It is preferable to provide a bent portion (13). That is to say, the bent portion (13) can prevent the slide guide frame (5) formed by the continuous connection of the rigid unit (6) from moving left and right, and the slide guide frame (5) This is because derailment from the support portion (12a) can be prevented. Of course, the cantilever (12) having the L-shaped cross section shown in FIG. 6 can also be used to support the sealing panel (4) in the screen device shown in FIG.

For example, the cantilever (1
As shown in FIG. 7, 2) is displaced by the sliding movement of the screen mounting frame (1), and does not hinder the sliding movement and the opening and closing of the screen (2). In order to enable such displacement, the cantilever (12)
Is preferably formed of a material having elastic recovery properties against bending and torsion. In this case, when the screen mounting frame (1) slides at the upper end by being guided by the upper rail (3), the cantilever (12)
Contacting the supporting portion (12a) of the supporting portion (12a)
As shown in FIG. 8, is subjected to bending stress in the direction of arrow A in FIG. 8, and is bent, twisted and pushed away by the torsional moment in the direction of arrow M generated by this, and the screen mounting frame (1) Slide movement and opening and closing of the screen (2). And cantilever (12)
Has an elastic recovery property against the above-mentioned bending and twisting, so that it returns to the initial state when the screen (2) is opened, does not remain bent, and does not break.

More preferably, the torsion when the screen mounting frame (1) slides is controlled as shown in FIGS.
At the upright portion (12b) of the cantilever (12). As described above, when the torsion is received by the upright portion (12b) rather than the horizontal support portion (12a), bending and breakage of the cantilever (12) can be more effectively prevented. .

As described above, the portion where the cantilever (12) is disposed may extend over the entire length of the upper rail (3) or the horizontal member (1).
Although only one part where bending or deformation is likely to occur in 1) can be used, mounting to the upper rail (3) can adopt, for example, the following structure.

That is, as shown in FIG. 1 and FIGS. 3 to 7, the cantilever (12) has a fixing projection (14) at a position opposite to the projecting end of the support portion (12a). On the other hand, on both sides (3a) and (3a) of the upper rail (3), a projection (14) is fitted, and a groove (15) for fixing the cantilever (12) is formed in the upper rail (3). (3) It can be formed in the length direction. When the cantilever (12) is attached to the upper rail (3), the projection (14) is formed of an elastic material, and is fitted into the groove (15) by elastic deformation to be fixed at a predetermined position, or the projection (14). Can be inserted into the groove (15) from its longitudinal end and slidable, and can be fixed at a predetermined position. FIG.
As shown in (1), when a plurality of cantilever beams (12) are arranged side by side at predetermined intervals on the upper rail (3), the cantilever beams (1)
Preferably, a spacer is interposed between 2). The spacer may have the same configuration as the protrusion (14) that can be provided on the cantilever (12).

In order to more easily arrange a plurality of cantilever beams (12) at predetermined intervals, as shown in FIG. 9, a plurality of cantilever beams (12) are formed in a rod-shaped projection (14). They can be connected and integrated laterally at a predetermined interval.
Projections (1) of the plurality of cantilevers (12) spaced at a predetermined interval.
By the integration in the lateral direction in 4), the trouble of interposing the spacer can be omitted, and the cantilever (12) can be easily attached to the upper rail (3). FIG. 9 illustrates a cantilever (12) having an upright portion (12b). The lateral connection and integration of the plurality of cantilevers (12) as described above is described in FIGS. The present invention can be equally applied to the cantilever (12) having no upright portion (12b) shown in FIGS.

Further, as shown in FIG. 10, the cantilever (12) has a seat (16) below the fixing projection (14).
Can be provided. The cantilever (12) has a projection (1
4) is fixed by the frictional force at the contact surface between the groove (15) and the groove (15). By further providing the seat (16),
As shown in FIG. 10, the seat portion (16) has the groove portion (15).
The upper rail (3), which forms the upper rail (3), comes into contact with the lower side from below, and a frictional force is obtained also at this contact surface, so that the cantilever (12) is more firmly fixed.

The seat (16) is a cantilever (12)
In the case of laterally connecting and integrating a plurality of cantilevers (12) shown in FIG. 9 at predetermined intervals, they are provided for each cantilever (12). Can be. If a stronger fixation is required, the seat (16) is not individually provided for each cantilever (12), but is a projection (14) for connecting and integrating a plurality of cantilevers (12). ) Can be provided over the entire length thereof.

FIG. 11 is a longitudinal sectional view showing an embodiment of the screen device of the present invention.

The screen device shown in FIG. 11 corresponds to the screen device shown in FIG. 21, and has a ceiling panel which contacts the upper edge of the screen (2) by its own weight inside the upper rail (3). Both sides of (4) can be supported by support portions (3a) of the cantilever (3) projecting toward the inside of the lower end of the upper rail (3). Therefore, even if the screen (2) is opened and the sealing panel (4) bends due to its own weight due to the size of the opened portion, the bent portion remains at the support portion (3) of the cantilever (3). 3a), the sealing panel (4) does not expose downward from the upper rail (3) and does not drop due to a positive pressure such as when wind blows. Will be retained. The bent portion generated in the sealing panel (4) does not hinder the sliding movement of the screen mounting frame (1), and a smooth opening / closing operation of the screen (2) is realized.

FIG. 12 is a longitudinal sectional view showing an embodiment of the screen device of the present application.

The screen device shown in FIG. 12 corresponds to the screen device shown in FIG. 22, and is provided above the upper edge of the screen (2) inside the upper rail (3). As shown in FIG. 5, the slide guide frame portion (5) having both elasticity and elasticity has upper and lower cantilever beams (12) and (12) which are vertically arranged at predetermined intervals as shown in FIG. The rail (3) is sandwiched and supported by support portions (12a) (12a) projecting toward the lower end inside. Therefore, as the length of the slide guide frame (5) pulled out from the inside of one screen mounting frame (1) as the screen (2) is closed becomes longer, the portion which should be kept linear in nature. In this case, even if the slide guide frame (5) is bent vertically, the downward bending of the slide guide frame (5) is prevented by the support portion (12a) of the lower cantilever (12). Also, upward bending is prevented by the support (12a) of the upper cantilever (12). For this reason, the linearity of the slide guide frame portion (5) inside the upper frame (3) is maintained even when receiving a positive pressure or a negative pressure such as when a wind blows, and does not shift from a predetermined position. A smooth opening and closing operation of the screen (2) is realized without hindering the screen mounting frame (1) from sliding.

FIG. 13 is a longitudinal sectional view showing an embodiment of the screen device of the present invention.

The screen device shown in FIG. 13 corresponds to the screen device shown in FIGS. 23 and 24, and is provided inside the upper rail (3) above the upper edge of the screen (2). The slide guide frame (5) formed by the continuous connection of the rigid units (6) has a substantially L-shaped cross section having upright portions (12b) on both sides, as shown in FIG. The support part (12a) projecting toward the inside of the lower end of the upper rail (3) of the support beam (12) can be supported. The upwardly bent portion (13) provided at the projecting end of the support portion (12a) can prevent the slide guide frame portion (5) from moving left and right. For this reason, for example, when the rigid unit (6) is made of an integrally molded resin in order to reduce the product cost, the dimensions change with the change of the external temperature, and the slide guide frame (5) is deformed. Even if the linearity cannot be maintained, the support portion (12a) of the cantilever (12) can support both sides of the portion where the linearity is lost, and does not bend. Therefore, the slide guide frame (5) does not hinder the sliding movement of the screen mounting frame (1), and a smooth opening and closing operation of the screen (2) is realized.

In the above embodiment, the cantilever (1)
2) is exemplarily arranged and fixed to the lower edge or the inner side surface of both sides (3a) and (3a) of the upper rail (3). The position of the cantilever (12) is not limited to the above, and the disposition portion of the cantilever (12) is the outer surface of both sides (3a) and (3a) of the upper rail (3). It is also possible.

For example, as shown in FIG. 14, the upper rail (3) has a cylindrical portion (3b),
When the sliding movement of the screen mounting frame (1) is guided along the lower end thereof, the cantilever (12) is connected to both sides (3) of the upper rail (3) due to the structure of the upper rail (3).
It becomes impossible to dispose and fix it on the inner side of a). Therefore, when the upper rail (3) is provided with such a tubular portion (3b), the cantilever (12) is provided on the outer side surfaces of both side portions (3a) and (3a) as shown in FIG. In this case, by providing the upright portion (12b), the support portion (12a) can be protruded toward the inside of the lower end portion of the upper rail (3).

As described above, the portion of the cantilever (12) provided on the upper rail (3) is located on both sides (3) of the upper rail (3).
a) As long as it is (3a), it may be any of the lower edge, the inner surface, or the outer surface, and is not particularly specified.

As shown in FIGS. 11 to 13, the screen device of the present invention may include a lower rail (17) opposed to the upper rail (3). The lower rail (17) can be disposed, for example, on a floor (18), a lower frame of a sash, or the like, and a lower end of the screen mounting frame (1), a lower edge of the screen (2) or a lower edge thereof. It guides the movement of the slide guide frame (5) arranged below. As the configuration of the lower rail (17), an appropriate one can be adopted according to the function required in each screen device.

Further, in the screen device of the invention of the present application, even in the case of the upper rail (3) having no cylindrical portion (3b), that is, the general upper rail shown in FIG. 1 and FIGS. Also in the case of the rail (1), the cantilever (12) can be arranged and fixed on the outer side surfaces of both sides (3a) (3a) of the upper rail (3). The cantilever (12) in this case is
It can be a cantilever (12) as shown in FIGS.
