Description

DETAILED DESCRIPTION OF THE INVENTION

[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 prevents the screen member from being bent, and a new fixed or movable bar-like rigid body as a frame or the like to which the screen member is attached is easily kept parallel to each other. It relates to a screen device.

[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. And these are installed as what has various materials and various structures according to the use purpose and the use.

[0003] As one kind of such a screen device,
Make the screen members themselves as independent as possible,
In addition, a device as shown in FIG. 7 is known as a device that can easily adjust the degree of opening and closing by the screen. The screen member (1), which is formed into a pleated shape so that it can be freely folded and unfolded, has a relatively good self-sustainability, is opened by sliding a movable frame (2) to which the screen member (1) is attached. Are opened and closed.

In such an apparatus, the pleated screen member (1) and the movable frame part (2) are characterized by their design and operability, but the screen member (1) is sufficiently independent. Rather, the left and right fixed frames (3) and (4) and the upper and lower fixed frames (5) serve as means for guiding the movement of the movable frame (2) while maintaining the movable frame (2) at a predetermined position.
Although provided with (6), it is difficult to keep the movable frame part (2) parallel to the left and right fixed frame parts (3) and (4) in its operation, and it is inevitably tilted, resulting in a pleated screen. There was a problem that it was difficult to maintain the member (1) independently.

As a means for solving such a problem, as shown in FIG. 8, a rigid bar (7) or a wire member is stretched to keep the movable frame (2) parallel, and a screen is provided. Means for increasing the independence of the member (1) are also known. However, in the example as shown in FIG. 8, the wire member of the rigid bar (7) is also exposed to the opening (8), so that the screen device is used very satisfactorily for partitioning the room. If this is attempted, entry and exit at the opening and movement will be hindered, and the installation of furniture and the like will also be restricted.

Therefore, the inventors of the present application have proposed a device as shown in FIG. 8 in which the rigid rod (7) and the wire member enter and exit through the opening (8) without being exposed at the opening (8). We have already proposed a pleated screen opening / closing device using a flexible member such as a thread or a wire and adding tension as a device that does not hinder movement at all. The screen device based on this completely new system has been put to practical use as a screen door or partition, and has attracted attention in terms of design, structure, and operation.

However, in the screen device according to the new system, the members corresponding to the movable frame (2) in FIGS. 7 and 8 are maintained and maintained in parallel with the left and right fixed frames (3) and (4). In order to slide, the yarn or wire is flexible and easily buckled, so that it is indispensable to use another structural member.

For this reason, the pleated screen member is supported with a simpler structure, and can be freely contracted and expanded, its independence can be enhanced, and it is easy to keep parallel with the fixed frame portion. New means were also desired.

[0009]

In order to solve the above-mentioned problems, the invention of the present application has a pair of bar-shaped rigid bodies opposed to each other on the left and right, and the opposed rod-shaped rigid bodies are used as a screen mounting frame portion. A screen member is attached and supported so as to be able to contract and expand between each other, and furthermore, each of a plurality of bar-shaped members arranged in parallel in the upper and lower directions between the opposing bar-shaped rigid bodies has a bar-shaped rigid body opposed to the left and right at one end. It is fixed to one, the other end is connected to each other as a free end via the other rod-shaped rigid body, and at least one of the plurality of rod-shaped bodies is provided by a bending contact guide part provided on the other rod-shaped rigid body. The rod-shaped rigid body is guided to be bent in the axial direction, and furthermore, the rod-shaped rigid body is guided to be bent and guided in a direction perpendicular to the axis by a bending-contact guide part provided at another position, and a plurality of rod-shaped bodies are connected to each other. To provide that screen device.

Further, according to the invention of the present application, in the above-described screen device, one end is fixed to one rod-shaped rigid body and the other end is fixed to the other rod-shaped rigid body at an intermediate position between the vertically arranged rods. At least one intermediate wire member connected to the free end portion of the rod-like body at the outside thereof is stretched, and this intermediate wire member is attached to and supports the screen portion in a contractible and deployable manner. A screen device characterized by the above is also provided.

The rigid body (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) can be folded and contracted or pulled out and deployed.

As for the screen member (11), the rods (14) and (15) penetrate the plane portions forming the respective pleat portions of the screen member (11), or the peaks (valleys) of the pleat portions. In the above, sliding contact is made via a ring fitting or the like. As a result, the independence of the pleated screen member (11) is better maintained.

Each of the pair of rods (14) and (15) is made of a material that does not easily buckle when a compressive force is applied in the axial direction and has a low axial Young's modulus. Then, using a fixture (17) or the like at their free ends,
Or it is connected and fixed without using it. For example, according to the above configuration, by moving the free end as the position of the fixture (17) left and right, the rod-shaped rigid body (1) is moved.
2) It can be moved while maintaining the parallelism of (13). Screen member attached to and supported by these (11)
Can also be folded and unfolded with independence.

6A), the rod-shaped rigid body (12) is bent and guided in the axial direction, and is further bent and guided in a direction perpendicular to the axis by a bending-contact guide part (16B) provided at another portion of the rod-shaped rigid body (12). The lower bar (15) is guided in a direction perpendicular to its axis via a rigid bar (12).

The rod-shaped body (14) and the rod-shaped body (15) are connected and fixed to each other at their free ends by a fixture (17) or the like. As described above, the rod-like members (14) and (15) are made of a material that is not easily buckled when a compressive force is applied in the axial direction and has a low Young's modulus in the axial direction. ), The rods (14) and (15) above and below are locked by the bending contact guide part (16A) so that they are always in a state of tension and kept at an equal distance therebetween, and the rod-like rigid bodies (12) ( 13) will always be kept parallel.

The rod state (1
4) As (15), a low-combustion steel rope or the like is exemplified. The bending contact guide parts (16A) (16B) may be, for example, a plurality of rotating pulley-shaped parts, or may be fixed as a curved body. The free end is
It may be made to move as it is, or it may be put in a space between wall surfaces or the like so that it cannot be seen from the outside.

FIG. 3 shows an example in which the free ends of the connected and fixed rods (14) and (15) as the fixture (17) are fixed to the guide surface (18). . FIG. 4 shows an example in which a plurality of three rods are further disposed, and FIG. 5 further shows an intermediate wire (19).
