Description

Multi-Functional Variable Partition

The present invention relates to a multifunctional variable partition, and to a partition capable of variably performing functions of not only partitioning a space, but also a blackboard capable of writing, a screen demonstrating an image, and a transparent window.

In more detail, the multifunctional variable partition of the present invention is composed of a plate-shaped upper partition and a lower partition connected up and down, and the upper partition is a back film glass, a variable panel, and a front film, respectively, on both sides of the color board for blackboard use. Glasses are closely adhered in order to form an overlapping shape, the edges are combined with a frame, and the variable panel is made of polymer dispersed liquid crystal (PDLC) that can be converted to a transparent state when power is supplied and to an opaque state when power is turned off. By connecting the power supply and the control unit, and supplying power to the variable panel configured on one side or the other side to make the variable panel on one side or the other side transparent, it can be used as a blackboard, or by turning off the power to the variable panel to make the variable panel opaque A bar that can be used as a screen using the diffuse reflection function from the front film glass The blackboard use and the screen use can be applied separately from both sides, and the color board is moved to the inside of the lower partition to accommodate it, and the upper partition has a color board By supplying power to the variable panels provided on both sides in the state in which is removed, the variable panel can be converted into a partition with a window-like view, and a lighting member is installed in the frame constituting the rim of the upper partition. It relates to a multi-functional variable partition with very high utility because it can be converted into various functions, such as being able to be used as lighting by applying power.

Partitions are mainly used to block the view to the outside to increase the concentration of work or to block the view to the inside for privacy in work spaces such as offices, and are produced in various patterns and shapes because the effect of the interior is emphasized. .

However, as described above, the purpose of the partition is to protect privacy by limiting the view of one side and the other side of the partition, but sometimes an outside view is necessary, and visual blocking is always preferable for interior effect or aesthetic function. It is a reality that is not accepted, and there is also a desire to remove partitions and create an open space.

In addition, since the partition itself occupies a predetermined space and causes a significant visual blockage, inconvenience due to the occupying of space is inevitable to install only as a space partition for privacy.

For example, if a new installation of a blackboard or screen board is required in a space where work, meetings, and work are performed, there is no suitable space and if a partition is installed, the existence of the partition will not only lower the utility value but also interfere with the use of the space.

However, in removing the partition to secure space, it is too much for the partition to be recognized only as useless, considering the improved concentration, privacy protection, and interior effect provided by the partition.

Therefore, at present, partitions for privacy protection, blackboards for meetings, and screen boards for video demonstrations must be separately provided, and operations such as movement, installation, separation, and storage must be carried out individually, and space occupation will increase. As a result, the space utilization is very low.

The lower partition 200 serves to partition a space and block the view between both sides, and may be made of an opaque material such as metal, wood, or plastic.

The upper partition 100 is located above the lower partition 200 and has a shape corresponding to the lower partition 200 and is configured with a width and thickness similar to that of the lower partition 200 so that the lower partition 200 extends upward. can be configured as

The upper partition 100 and the lower partition 200 have a wide shape viewed from the front and rear and a narrow thickness viewed from the side, and the upper partition 100 may have a frame formed on the edge and the lower partition 200 ) may be a single plate or may be constructed by a frame.

Unlike the lower partition 200 , the upper partition 100 may be converted and used as various functions such as a blackboard, a screen, and a window according to the purpose of the present invention.

To this end, the upper partition 100 may include a first frame 110 , a second frame 120 , and a board frame 130 , and the first frame 110 includes a first variable part 111 . , the second frame 120 may include the second variable portion 121 , and the board frame 130 may include a color board 131 .

The first frame 110 is a frame configured on one edge of the upper partition 100 , and the first variable part 111 may be mounted on the inside in the form of a panel.

In addition, the second frame 120 is a frame configured on the other edge of the upper partition 100 , and the second variable part 121 may be mounted on the inside in the form of a panel.

The board frame 130 is a frame provided between the first frame 110 and the second frame 120 , and the color board 131 may be mounted therein.

The first variable part 111 and the second variable part 121 are opaque when power is not normally applied, and may be utilized as a shape and function of a general partition.

When the shape of the upper partition 100 is viewed in a vertical section from one side, the first variable part 111 , the color board 131 , and the second variable part 121 are arranged in the order or vice versa. can

The first variable part 111 and the second variable part 121 have a shape in which a film-type glass and a panel are layered and overlapped, and can be switched to a transparent or opaque state by supplying or blocking power, respectively. do.

That is, the first variable portion 111 and the second variable portion 121 have the same characteristics. When power is supplied, they are converted to be transparent and formed like a glass window, and when the power is turned off, they are converted to opaque and combined with a white screen board. transformed into the same shape.

The first variable portion 111 and the second variable portion 121 may be configured to be in contact with one side and the other side of the color board 131, respectively, and control of the transparent and opaque state by supplying and blocking power may be performed individually. can

The first variable portion 111 and the second variable portion 121 have the same configuration, respectively, from the outer tip toward the center, front film glass 111a, 121a, variable panels 111b, 121b, and rear film glass, respectively. It may be configured in the order of (111c, 121c).

That is, if the first variable portion 111, the color board 131, and the second variable portion 121 are sequentially configured from the tip of one side to the tip of the other side when viewed in a vertical section from the side of the upper partition 100, the The detailed configuration is sequentially the front film glass (111a), the variable panel (111b), the rear film glass (111c), the color board 131, the rear film glass (121c), the variable panel (121b), the front film glass (121a). can be configured as

The front film glass (111a, 121a) is a film-type glass that covers the entire surface of the glass by chemical etching directly on the surface of the glass to prevent glare (anti-glare) to have a diffuse reflection function, and increase the clarity when used as an image screen. It can be applied to have a light transmittance of 80% or more.

The rear film glasses 111c and 121c are film-type glasses disposed on the rear surfaces of the variable panels 111b and 121b, and may be provided as backboard glass having high light transmittance.

The variable panels 111b and 121b may be configured in close contact between the front film glasses 111a and 121a and the rear film glasses 111c and 121c, and the power supply device 211 receiving power control from the control unit 212 and It can be connected to supply and cut off power.

The variable panels 111b and 121b may be composed of a polymer dispersed liquid crystal (PDLC), and when power is supplied according to the material characteristics, the variable panels 111b and 121b are converted to transparent, and thus the opposite side The view becomes possible, and when the power is cut off, the variable panels 111b and 121b are converted to opaque so that the opposite view can be blocked.

Therefore, the configuration of the front film glass (111a, 121a), the variable panels (111b, 121b), and the rear film glass (111c, 121c) constituting the first variable part 111 and the second variable part 121, respectively, is a variable panel. According to the physical properties of (111b, 121b), it can be converted and used for various purposes, and the conversion, which is the main feature of the multifunctional variable partition 10 of the present invention, will be described in detail as follows.

First, when power is supplied to the variable panels 111b and 121b, the polymer dispersed liquid crystals are arranged in a uniform arrangement in the direction of the electric field, thereby transmitting light, and the variable panels 111b and 121b are converted to a transparent state. is done

Here, the physical properties of the polymer dispersed liquid crystal and the transparent and opaque conversion through it utilize a known technique commonly used in the art, and thus a detailed description thereof will be omitted.

On the other hand, when power is supplied to the variable panels (111b, 121b) and becomes transparent, the light passes through the front film glass (111a, 121a), the variable panel (111b, 121b), and passes to the rear film glass (111c, 121c). and eventually reaches the color board 131 and is reflected.

The color board 131 may be provided as a colored panel provided inside the board frame 130 by being painted with a color such as green or black used for a blackboard, and may be of a film glass type.

When the variable panels 111b and 121b become transparent, the first variable portion 111 or the second variable portion 121 is shown in the form of a color board 131 on which film glass is mounted, and the user can use water chalk, board The first variable part 111 or the second variable part 121 may be used as a blackboard by using a writing implement such as a marker.

Since the first variable unit 111 and the second variable unit 121 may be configured to separately supply power, the first variable unit 111 and the second variable unit 121 may be configured to supply power and supply power to the first variable unit 111 and the second variable unit 121 . Transparency or opacity conversion by blocking can be performed separately.

That is, power is supplied to the first variable part 111 to make the variable panels 111b and 121b transparent, and then used as a blackboard in the first frame 110 , but power is supplied to the second variable part 121 located on the opposite side. Blocking means that it can be used for other purposes.

When the power to the variable panels 111b and 121b is cut off, the polymer dispersed liquid crystal has no electrical direction, so the liquid crystal molecules are arranged irregularly and randomly, causing light scattering to prevent light from passing through the variable panels 111b and 121b. do.

Therefore, the variable panels 111b and 121b with power cut off are converted to an opaque state. Since the light passing through the front film glass 111a and 121a is reflected from the variable panels 111b and 121b, it is opaque to our eyes. It is visible as a glass panel shape with a white background.

In this state, the first variable part 111 or the second variable part 121 may function as a screen board for demonstrating an image.

That is, when power is cut off to the first variable unit 111 or the second variable unit 121, a white screen board is formed, and the screen board can be used for image reproduction through image projection using beam projection. there will be

This may also be used for separate purposes in the first variable portion 111 and the second variable portion 121 .

That is, power may be supplied to the first variable unit 111 to be used as a blackboard, and power to the second variable unit 121 may be cut off from the opposite side to be used as a video screen or used as a partition function.

Meanwhile, the power supply device 211 for supplying power to the first variable unit 111 and the second variable unit 121 and the control unit 212 for controlling the supply of power may be provided inside the lower partition 200 . .

And it may be configured to supply power to the variable panels 111b and 121b provided in the second variable part 121, respectively.

In addition, the central portion of the receiving space 210 of the lower partition 200 may be provided with a space in which the color board 131 is inserted and accommodated.

The color board 131 may be accommodated by moving downward into the inner space of the lower partition 200 by an electric moving member in a state located in the center of the upper partition 100 .

To this end, a rail may be configured for smooth movement of the color board 131 on the inside of both side edges of the board frame 130 , and a plurality of rotating rollers moving along the rails on both sides are located on both sides of the color board 131 . It can be made to reciprocate between the color board 131 and the upper partition 100 and the lower partition 200 while rotating by electrical control and power supply while being coupled to each other.

To this end, the power supply unit 211 and the control unit 212 provided on one side of the lower partition 200 may be configured to be connected to the movable member mounted on the color board 131 as well as the variable panels 111b and 121b. .

As the color board 131 moves into the lower partition 200, the multifunctional variable partition 10 of the present invention can also function as a window.

That is, when power is supplied to the variable panels 111b and 121b respectively provided in the first variable part 111 and the second variable part 121 in a state in which the color board 131 is removed from the upper partition 100, the The first variable portion 111 and the second variable portion 121 may be converted to a transparent state.

In this state, since the color board 131 does not exist between the first deformable part 111 and the second deformable part 121 , the upper partition 100 may be formed as a window having a double-glazed window.

Therefore, the user can use the multifunctional variable partition 10 of the present invention as a partition to partition a space and protect privacy, and when necessary, supply power to one side and use it as a blackboard, and cut the power to the other side to use it as a video screen. Not only that, after moving the color board 131 from the upper partition 100 to the lower partition 200, by supplying power to both the variable panels 111b and 121b on both sides, it can be used by converting it to an outside view through a window. have.

At this time, the moving member of the color board 131 may be configured to include a manual moving member that can be moved by manual operation as well as an automatic moving member by an electric device.

The detailed configuration and conversion function of the upper partition 100 applied to the multifunctional variable partition 10 of the present invention described above is not limited to only the partition, and is not applied to office glass walls, building exterior windows, advertisement bulletin boards, educational blackboards, etc. It can be expanded and used in various cases.

On the other hand, the multi-function variable partition 10 of the present invention may be used as a lighting device.

To this end, at least one or more lighting members 112 and 122 may be mounted on the surface of the first frame 110 or the second frame 120, and as an embodiment of the present invention, a plurality of lighting members 112 and 122 are provided. The first frame 110 or the second frame 120 may be configured to be sequentially mounted at predetermined intervals along the edge of the frame.

The lighting members 112 and 122 may be operated to assist the demonstration effect of an image in a state in which power is turned off to the first variable part 111 or the second variable part 121 and configured in a screen state, and the first variable part 121 may be operated. Power is supplied to the 111 or the second variable unit 121 and converted to a blackboard use, which may be used to increase the educational effect, which may be selectively applied according to the purpose of use of the lighting members 112 and 122 .

In addition, the lighting members 112 and 122 may be used simply as a lighting function or may be used for interior effects.

When the lighting members 112 and 122 are used as a pure lighting function or an interior effect, they may be used after being moved to a desired position through a moving means provided in the support member 220 .

The lighting members 112 and 122 may also be driven separately in the first frame 110 and the second frame 120 , and thus supply and cut off power to the first variable unit 111 and the second variable unit 121 . can be selectively combined with the lighting members 112 and 122 in a state in which each is applied.

In addition, even in a state in which the color board 131 is moved to the lower partition 200, the lighting members 112 and 122 and the first variable part 111 or the second variable part 121 according to the purpose of use of the multi-function variable partition 10 are installed. It can be used individually or in combination.

On the other hand, the multifunctional variable partition 10 of the present invention may be configured in such a way that the upper partition 100 is provided with a single variable panel (111b or 121b).

That is, the upper partition 100 may have a structure including only the first frame 110 and the board frame 130 or only the second frame 120 and the board frame 130 .

Even in this case, the functions and operations of the above-described first variable unit 111 or second variable unit 121 may be identically performed, and thus all functions as partitions, blackboards, screens, windows, and lighting devices may be used. .

The form in which a single variable part is formed can be applied for the purpose of increasing space utilization or reducing unnecessary configuration when it is used only on one side and is not used on the other side when it is located in close contact with the office wall, or office glass in contact with the hallway It may be applied, installed and used when the variable part cannot be configured on the other side, such as inside a wall.

The configuration in which a single variable part is formed may also be used mounted in the form of a movable partition, and it may be fixedly installed on the wall without the support member 220 and used, and the purpose is to use the multifunctional variable partition 10 of the present invention. and may be selectively determined depending on the location.

An example of use of the multifunctional variable partition 10 according to a preferred embodiment of the present invention based on the above description is as follows.

For example, it is assumed that the user on one side of the multifunctional variable partition 10 installed uses the configuration of the first frame 110 and the user of the other side uses the configuration of the second frame 120 .

Both the user on one side and the user on the other side are currently using the multi-function variable partition 10 as a pure partition function.

Now, the user on one side wants to conduct a meeting, and the user on the other side decides to proceed with the training by demonstrating the video.

The user on one side operates the control unit 212 to turn on the power supply device 211 connected to the first variable unit 111 to supply power, thereby making the variable panel 111b transparent.

Accordingly, the first variable part 111 is transparent, and the color board 131 is converted into a blackboard provided as a white board, and a user on one side can conduct a meeting while writing using a writing instrument such as water chalk or a board marker. .

At this time, if the indoor lighting of the first variable part 111 is dark and the screen is not easily seen, the user on one side supplies power to the lighting member 112 mounted on the edge of the first frame 110 to activate the lighting function. can brighten

Accordingly, the user on one side can use the functions of the blackboard and the lighting member 112 at the same time.

On the other hand, the user on the other side turns off the power supply connected to the second variable unit 121 to view the video and turns off the power, thereby making the variable panel 121b opaque.

Now, the second variable part 121 has a shape of a white screen board, and the user demonstrates an image on the second variable part 121 using an image projection device such as a beam projection.

Likewise at this time, the user may selectively operate or not operate the lighting member 122 mounted on the edge of the second frame 120 .

If both users of one side and the other side can view both sides after the meeting and training are finished and light can pass through, supply power to both the first variable unit 111 and the second variable unit 121. do.

And at the same time, the color board 131 is moved to the receiving space 210 of the lower partition 200 .

Since the first variable part 111 and the second variable part 121 are converted to a transparent state and the color board 131 does not exist in the middle part, users of one side and the other side can use the first variable part 111 . It is possible to share a view and light with each other through the transparent window composed of the second variable part 121 and the second variable part 121 .

On the other hand, as an additional embodiment of the multi-function variable partition 10 of the present invention, the supply or cut-off of power to the first variable part 111 and the second variable part 121 can be adjusted through a screen touch.

The first variable part 111 and the second variable part 121 are equipped with a touch screen panel to which an infrared sensor is attached between the front film glass 111a and 121a and the variable panels 111b and 121b in an infrared manner. It may be configured to recognize a screen touch.

Therefore, unlike the control unit 212 controlling the supply and cut-off of power to adjust the transparency of the variable panels 111b and 121b, in the infrared screen touch method, the front film glass 111a, 121a is touched by the infrared sensor. It can be detected and switched on and off, so that it can be easily converted to the use of a blackboard and a screen.

In addition, as another additional embodiment of the multifunctional variable partition 10 of the present invention, the transparency of the variable panels 111b and 121b may be configured to be adjusted according to a predetermined step ratio.

That is, by electrically adjusting the light transmittance level of the polymer dispersed liquid crystal, it is possible to adjust the transparency to be differentially converted in stages from the highest transparent state to the lowest opaque state.

This adjusts the frequency and phase of the AC power supplied to the variable panels 111b and 121b, and adjusts the duty cycle, which is the ratio of the high-state and low-state waveforms of the pulse waveform to the frequency pulse. By supplying different power in a manner of modulating the width, it is possible to mount a function to control the light transmittance of 90% or more in stages, starting with the opaque of the variable panels 111b and 121b.

This can provide a basis for greatly expanding the use of the variable panels (111b, 121b) compared to the use of a blackboard or screen while adjusting the variable panel (111b, 121b) to be transparent or opaque according to the supply and cut off of power.

However, since the method of modulating by adjusting the duty cycle of the pulse waveform according to the magnitude of the AC voltage signal is a technique commonly used in the art, a detailed description thereof will be omitted.

The embodiments of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains will appreciate that various modifications and equivalent other embodiments are possible therefrom.

Therefore, it will be well understood that the present invention is not limited to the form mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.

It is also to be understood that the present invention includes all modifications, equivalents and substitutions falling within the spirit and scope of the invention as defined by the appended claims.
