[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen device. More specifically, the invention of this application is useful for opening and closing indoor window openings, partitions, screen doors, etc., and even outdoors, has a high degree of freedom of installation, and is excellent in shape stability, The present invention relates to a new screen device which is easy to operate and has good appearance.

[0002]

2. Description of the Related Art Conventionally, in a house or an office building, a screen device having various structures is used as a device for opening and closing a window opening or a partition.
Typical examples thereof include curtains, blinds, movable partitions, and partitions. However, these are installed as materials having various structures and various structures according to the purpose of use and purpose of use. An integral or independent fixed upper and lower and left and right fixed frame portions were indispensable requirements. Therefore, there is a problem that the design and installation of the screen device are naturally restricted by the presence of the fixed frame.

[0003] Although such restrictions are relatively inconspicuous as a problem in the installation of a screen device in an opening of a window or a wall, when the screen device is used as a partition, a partition, or the like, its design and visual appearance are poor. This is a major problem in installation and operation. That is,
For example, as illustrated in FIG. 7, when a screen device is configured by a screen member that can be freely folded and unfolded, the screen member (1) needs to have a screen member ( A first fixed frame (3) also having a screen member (1) mounted thereon, together with a movable frame portion (2) having mounted and supported 1);
A second fixing frame (4) opposed thereto, and upper and lower third fixing frames for fixing the first and second fixing frames (3) and (4).
The fixed frame (5) and the fourth fixed frame (6) are indispensable.

When the partition shown in FIG. 7 is used as a partition,
Even though the screen member (1) can be opened and closed, the first to fourth fixed frames (3), (4), (5), and (6) are very eye-opening, which hinders movement of people and installation of furniture and the like. May occur. Further, as shown in FIG. 8, when the bar member or the like of the wire member (7) is provided in the means for preventing the screen member (1) from bending or the like and imparting its independence, these problems occur. Will be more serious.

[0005] For this reason, the conventional screen devices of various types remain as a problem that the restriction due to the existence of the fixed frame portion is not solved even if the device is used as a window opening / closing device or as a partition. Was. Accordingly, the inventors of the present application have solved the above-mentioned drawbacks of the conventional screen device, greatly improved the design and installation restrictions due to the presence of the fixed frame portion, and have improved the installation and operability as well as the design flexibility. We proposed a new screen device that is good and has excellent appearance.

In this newly proposed screen device (Japanese Patent Application No. 8-181926: Japanese Patent Application Laid-Open No. 9-88456), for example, as exemplified in FIG. As a frame part, a pair of screen mounting frame parts (12) and (13) for mounting and supporting a screen member (11) that can be freely folded and unfolded, and another pair of slide guide frame parts (14) and (1).
5).

With respect to the screen mounting frames (12) and (13), one of them, for example, the screen mounting frame (12) is fixed to, for example, a wall surface, a window opening end, or a column, and the other screen mounting frame. The part (13) is movable or vice versa. Further, both are movable, and one of them is temporarily fixed and the other is moved so that the screen member (11) is folded and contracted or pulled out and deployed.

[0008] A pair of slide guide frames (14) (1)
Regarding 5), each of them has bending elasticity,
For example, in the example of FIG. 9, one end of each is fixed at the fixing portion (131) of the screen mounting frame portion (13), and the other end is formed by folding and contracting and expanding the screen member (11). Bends and slides along the screen mounting frame (12). More specifically,
When the screen member (11) is folded and contracted, it is bent and inserted into the hollow portion (121) of the screen mounting frame (12). And the slide guide frame portions (14) (15)
Is the elastic repulsive force due to this bending, and the screen member (1
When the action force for contraction in 1) is released, the bending slide is stopped. By this stop, the interval between the screen mounting frame portions (12) and (13) is maintained at a predetermined value.

FIG. 10 and FIG. 11 show that one of the screen mounting frames (12) and (13) is fixed to a wall opening end (16) as a fixed frame and the other is a movable frame and the ceiling surface (1).
This shows an example in which a partition is formed between 7) and the floor (18). That is, in the screen device proposed by the inventors, unlike the related art, the fixed frame portions on the four sides are not necessary, and one fixed frame portion is sufficient.

Further, a stopper (19) for fixing a stop state at a required position is provided on the movable frame portion, and the stopper (19) is attached to a floor surface (18) or a ceiling surface (17). You may make it contact and fix. Of course, this stopper is not always necessary. The screen device can be installed in a window opening or the like.

Further, a caster having a stopper device may be provided at a lower end portion of the screen mounting frames (12) and (13) to constitute a movable partition or the like. As a result, for example, the caster of the screen mounting frame (12) is fixed, the screen mounting frame (13) is operated as a movable frame, and the screen member (11) is folded and contracted or pulled out and developed to obtain a required screen. Screen mounting frame (13) as a movable frame with a partition having an area
Can be stopped and fixed. of course,
Conversely, the screen mounting frame (12) may be a movable frame. In this case, as is clearer, there is no fixed frame of the surrounding four sides in the conventional screen device, and the degree of freedom of design and installation as a partition or the like is large and the appearance is excellent.

Further, a wire member can be used to give the screen member (11) self-sustainability. For example, as shown in FIG. 12, a pair of screen mounting frames (12) facing each other in the upper, lower, left and right directions.
(13) and slide guide frame portions (14) and (15) are provided, and the screen mounting frame portions (12) and (13) have a pleated screen member (1) having a plurality of pleat portions.
1) are attached and supported so as to be foldable and expandable in the opening and closing direction, and wire members (21) and (22) for supporting the pleated screen member (11) in the opening and closing direction are stretched.

Then, the pleated screen member (1)
(1) A pair of screen mounting frames (12) (1)
3) One screen mounting frame portion (12) is a direction changing means (23a) for the wire members (21) and (22).
(23b), (24a) and (24b). On the other hand, a pair of upper and lower slide guide frames (14, 15) that do not support the pleated screen member (11) are fixed to the screen mounting frame (13).

The upper and lower slide guide frames (14) (1)
5), one end is fixed to the screen mounting frame portion (13), and is bent and slid along the other screen mounting frame portion (12) together with folding and unfolding of the pleated screen member (11). At the slide stop position of the pair of screen mounting frames (12) (1).
Keep the interval of 3) at a specific interval.

In this case, the wire member (21)
(22) connects the bent ends of the slide guide frames (14) and (15) to the screen mounting frame via the direction changing means (23a) (23b) (24a) (24b) of the screen mounting frame (12). Fixing points (2
5) It is stretched between (26), (27) and (28), and is a screen mounting frame (12) and a screen mounting frame (13).
Pleated screen member (11) is supported in the opening and closing direction.

In this structure, the screen mounting frames (12) and (13) are independently slidable, but when used, one is fixed and the other is movable. In this example, it is assumed that the bending slide guide frame portions (14) and (15) have strength enough not to buckle against the tension of the wire members (21) and (22). Of course, the support of the pleated screen member (11) and the like by the wire member is not limited to the example of FIG.

That is, for example, as described above, the new screen device already proposed has two pairs of frame portions facing each other in the upper, lower, left and right directions, and one pair of the opposite frame portions is the screen mounting frame portion. As, a screen member is attached and supported so as to be able to contract and expand freely between each other, and the other pair of opposing frame portions are screen devices each constituting a slide guide frame portion, and the pair of screen mounting frame portions are Either one or each is movable in the direction of contraction and expansion of the screen member, and the pair of slide guide frames has bending elasticity, and each of them has a screen mounting frame at one end. The other end is bent along the other screen mounting frame as the screen member contracts or expands. And it is characterized by keeping between said screen mounting frame portion a pair of opposed at a predetermined bending slide position to a required spacing.

In this screen device,
The slide guide frame portion (14) having the bending elasticity.
As (15), a belt-shaped spring material commonly called a convex, a combined body of a belt-shaped spring material and a block connected body such as plastic, a combined body of belt-shaped materials having different flexural moduli, or a flexural elasticity of a fiber-reinforced plastic belt-like material. Are appropriately used.

With the above-described configuration, a disadvantage of the conventional screen device due to the presence of the fixed frame portion is eliminated, and a new screen device having a large degree of freedom in design and installation, and excellent operability and appearance is realized. It can be installed in various indoor and outdoor areas, including window opening / closing devices, partitions, and screen doors. However, on the other hand, a detailed examination of the inventors of the present application has revealed that further improvement is required with respect to the newly proposed screen device. This is because, for the slide guide frame portion having bending elasticity in the screen device, adjusting the characteristic balance between rigidity and flexibility to stably and independently hold the screen member, particularly, the screen member It is not always easy to adjust this balance when using a wire member to give independence to the screen member. When the slide guide frame is shrunk in the screen member, slid in the storage direction, or stopped at a predetermined position In this case, due to the elasticity of the slide frame portion, there is a problem that the curved portion may be bent at a portion where the linearity should be originally maintained, and that the shape stability of the screen member and a favorable opening / closing operation may be difficult. is there.

Therefore, in the invention of this application, the design and installation of the conventional screen device, which is a feature of the screen device already proposed by the present inventors, due to the existence of the conventional fixed frame portion is eliminated. It has the advantage of having a high degree of freedom and good operability and appearance.
In order to further develop this feature, as described above, an improved new screen excellent in shape stability and operability of the screen, which can solve the problem of the slide guide frame having bending elasticity. It is intended to provide a device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention of this application has the above-mentioned features, but the embodiments will be described below with reference to the drawings, and the embodiments will be described in more detail.

[0025]

FIG. 1 is a partially cutaway front view illustrating a screen device of the present invention installed in an opening such as a window. For example, as shown in FIG. 1, in the screen device of the present invention, the left and right screen mounting frames (12)
Between (13), a pleated screen member (11) is attached and supported so that it can be folded and contracted and deployed. In this device, the slide guide frame (14)
(15).

In this example, the screen mounting frame (13)
Are fixed to the frame of the opening with an anchor member (31), and the screen mounting member (12) is movable in the direction of contraction and expansion of the screen member (11) (arrows in the figure). . Slide guide frame (1

It slides along the frame portion (12), and a predetermined sliding device is used to maintain a predetermined interval between the screen mounting frame portions (12) and (13). More specifically, in this example, when the screen member (11) is folded and contracted, the slide guide frame (15) is attached to the screen mounting frame (12) as shown in FIG. ) Hollow part (1)
21). Conversely, the screen member (1
At the time of deployment of 1), the slide guide frame portion (15) is pulled out from the hollow portion (121) of the screen mounting frame portion (12). Slide guide frame at the top of the opening (1
The same applies to 4).

The hollow portion (121) may be a single space or a slide guide frame (1).
4) is directed downwards, and the slide guide frame (15) is inserted into the hollow portion (121) so that the slide guide frame (15) faces the interior upward and passes each other. 14) The space for each of (15) may be divided by a guide projection or a partition.
This division may be either left or right or front and back. When the space is divided as a space, the slide guide frame (1
4) It is possible to increase the storage length of the slide guide frame portions (14) and (15) even with a screen device having a long (15). That is, the screen device is suitable even when the width of the opening is large.

In the screen device of the present invention, the slide guide frame (15) is arranged in one direction, that is, along the screen mounting frame (12), so that the above-mentioned insertion and withdrawal can be freely performed. Can be bent upwards , but in the opposite direction, it cannot bend and keep it straight .
And a rigid body provided with a stopper mechanism. In the case of the slide guide frame portion (14), it can be bent downward, but cannot be bent in the opposite direction.

[0029] Then, the slide guide frame portion as such rigid (14), (15), for example as also illustrated in FIGS. 1 and 2, configured as a coupling-like rigid body of the rigid unit (32) Have been . FIG. 3A shows FIG.
FIG. 3B is a sectional view taken along line AA, FIG. 3B is a front view, and FIG.
3C shows a side view, and FIG. 3D shows a bottom view.

As for the slide guide frames (14) and (15) of the present invention which are constituted by a rigid body as a connected body of the rigid units (32) or an integral rigid body, for example, the rigid unit (32) shown in FIG. As shown as an example, the side wall portion (322) is provided opposite to the partition wall portion (321) as a bridge portion. In the case of the illustrated rigid unit (32) in FIG. 3, the partition (321) is connected to a connecting portion with an adjacent rigid unit.
It has steps (321A) and (321B), and these steps are part of the stopper mechanism.

In the step (321A), the upper surface of the end is notched, and in the step (321B), the lower surface of the end is notched. For this reason, at the connecting portion between the adjacent rigid units (32), the step (321B) is placed above the step (321A).
Are overlapped, and the rotation of the adjacent rigid unit (32) at the time of connection about the projection (323) as the rotation center at the time of interconnection can freely move upward of the arrow α in FIG. 3 (b). It is possible, but is prohibited below the arrow β.

In the case of the rigid unit (32) shown in FIG. 3, the protrusion (32) is provided on the side wall (322).
3) and the protrusion (32) of the adjacent rigid unit (32).

The angular pin structure in this case also constitutes the stopper mechanism in the present invention. That is, in FIG. 4, the adjacent rigid units (32A) (3
2B) and (32C) are shown as connected. For example, in the rigid unit (32A), the protrusion (323) and the small protrusion (325) provided on the side wall (322) are adjacent to the rigid unit (32B). By being inserted into the hole (324) and the curved slot (326). Rigid unit (32A) and rigid unit (32B)
The relationship is the same.

In this connection, the rigid unit (32
The small projection (325) of A) is connected to the adjacent rigid unit (3).
When the rigid unit (32B) is at the upper end of the curved elongated hole (326) of FIG. 2B, that is, at the position of FIG. 4, the rigid unit (32B) is rotatable about the protrusion (323) in the direction of the upper arrow α. It cannot rotate in the direction of the lower arrow β. This is because the small protrusion (325) and the curved elongated hole (326) constitute a stopper mechanism.

An angular pin structure or an angular key structure as a stopper mechanism is used as such a stopper mechanism in one direction of a slide guide frame portion as a connected body of the rigid unit (32), for example, the direction of FIG. : Bending is possible in direction α, but bending is prohibited in direction β, and as a result, the linearity of the slide guide frame is maintained. Needless to say, the stopper mechanism of the present invention includes the step (321A) provided in the partition (321).
(321B), and the present invention is not limited to the angular pin structure formed by the small projections (325) and the curved elongated holes (326). Consideration is given to providing a stopper mechanism by providing a step and a projection on the side wall.

Slides will be smoother.

Of course, the roller (12
2) and the guide rail (33) are not always necessary. Further, another means that performs the same function as this may be appropriately adopted. In the above examples including FIG. 1, as shown in FIG. 5, the height position of the upper slide guide frame (14) can be adjusted by the rail member (34). It has been.

The rail member (34) is not always necessary, and serves to make the slide guide frame (14) slide more smoothly. Also, as exemplified in FIGS. 1 and 2, the screen member (11)
It is composed of a pleated net made of resin,
The screen member is not limited to the net member, and may be various members such as a cloth member, a sheet member, and a connecting plate member. In the case of a pleated screen member, for example, as shown in FIG. 6, the pleated shape opening angle at the time of maximum deployment can be set to, for example, about 90 °. The pleated screen member (11) is folded, for example, as shown in FIG.
The screen member (11) can be housed in the space (13A) inside the 3), but the screen member (11) is replaced with such a pleated folding storage system, for example, a fixed screen mounting frame ( 13) The roller may be wound up and stored in a roller winding device provided therein, and may be drawn out and developed from the roller winding device. In the case of this roller winding device, the screen member (11)
The winding direction is urged by the rotation of the drawer
A spring mechanism for storing a force may be provided. Of course, a winding system using a small electric motor may be used.

Further, as shown in FIGS. 1 and 2 and FIG. 6, in the above example, the wire members (21) and (22) are passed through the pleated screen member (11). However, this wire member (21) (2)
2) is not essential. Screen member (11)
Plays an effective role in giving independence to Similarly, in the screen device exemplified above, as shown in FIGS. 1 and 6, even if a minute gap is formed between the movable screen mounting frame portion (12) and the opening frame portion, this can be shielded. The mohair (35) is arranged as described above. Various types of mohairs (35) or other elastic bodies in the form of fibers are used, but these are not indispensable for the screen device of the present invention.

For example, in the screen device of the present invention exemplified as described above, the slide guide frame (1)
4) (15) is a rigid body having a side wall portion opposed to a bridging portion, for example, the partition wall portion (321) as described above, and is bendable in one direction but in the other direction. Is provided with a stopper mechanism to stop the bending of the rigid body and keep the rigid body in a straight line.
(15) is excellent in shape retention of the screen member (11) because it has rigidity to maintain linearity, as is clear from the above example, and can be applied to the movable screen mounting frame (12). Bending operability associated with insertion and withdrawal of the same from there, and excellent stopping performance at a predetermined position.

Of course, the slide guide frame (14)
