Description

  The present invention relates to a pseudo window device, and more particularly to a pseudo window device capable of reproducing and displaying an outdoor sign.

As a conventional pseudo window device, for example, those described in Patent Literature 1 and Patent Literature 2 are known.
In the former, an opening is formed in a wall of a windowless space as a multipurpose window, a screen is installed in the opening, and video equipment is arranged on the back of the screen.
The project aims to create a natural space by projecting an image on a screen using image equipment. In addition, by providing air-conditioning equipment, scent generators, lighting equipment, and sound equipment, we are trying to create a space that is generally close to the natural environment.
The latter relates to an Akari Shoji lighting fixture, in which a heat source is arranged in a lighting fixture storage room, and a projection body that sways by a hot air flow is arranged close to the Akari Shoji.

  However, in the conventional pseudo window device, the former uses an artificial video projected on a screen and artificially adds environmental sounds and the like thereto, and requires a complicated device configuration, and However, as a result of being recognized as an artificial thing such as video and audio, it was easily found and recognized that a pseudo window was present in the space. In other words, the scenery and sound reproduced by artificial means cannot be emphasized and the user cannot forget that it is a pseudo window. In the latter, the use of a heat source raises concerns about safety, and it is difficult to control the movement of the projection body, which is insufficient to convey an outdoor sign.

Therefore, as a result of earnest research, the inventor did not project an electronically created image on the screen, but simply projected the plant-like object set behind the screen, and performed a predetermined movement with respect to this object (its shadow). It has been found that the above-mentioned problems can be all solved by the application, and the present invention has been completed.
That is, the pseudo window device according to the present invention is an outdoor sign, that is, as if it were a real window (a window facing the outside), with an extremely simple device configuration and by reflecting natural movement in the shadow of an object. A feeling like that can be given.

That is, an object of the present invention is to provide a pseudo window device having a simple configuration.
Further, the present invention provides a pseudo window device which can faithfully reproduce the outdoor natural situation by moving the shade of a plant-like object to give a sense of the outdoor atmosphere, and obtain the recognition of a normal window facing the outside. It is intended to provide.

  The invention according to claim 1 includes a window frame, a screen supported by the window frame, a plant-like object arranged to be swingable behind the screen, and a light source that projects the plant-like object onto the screen. This is a pseudo window device provided with driving means for swinging a plant-like object.

Window frames include triangles, squares, and circles. Further, in addition to the window frame installed on the vertical wall, the case where it is installed on the ceiling and the case where it is installed on the floor surface are included. Further, in addition to installation on the wall of a building, the invention can be applied to vehicles such as rockets, aircraft, submarines, and large steamships. Further, the window frame may be of a built-in type to a building wall or a wall-mounted type. The window frame can be made of metal, wood, plastic, or the like.
The screen uses, for example, a translucent or white polycarbonate diffuser plate. In addition, a plastic film or a light shoji such as Japanese paper can be used. In order to be able to project the shading shadow of the plant-like object, the material of the screen and the intensity of the light from the light source are determined and controlled as appropriate. As a light source, an LED light, a halogen lamp, a fluorescent lamp, or the like is used. The screen may be configured to cover the whole or a part of the opening formed by the window frame. The screen may be detachable from the window frame. It is convenient when changing every season. For example, a screen material is detachably attached to the window frame with a planar fastener or the like.

  As the plant-like object, one bamboo bamboo, one or more branches and leaves of other plants, and flowers are suitable. The proportion of the branches and leaves with respect to the entire screen is set as appropriate, but is set to a size and length that can reflect the slight movement. It is also possible to set a plurality of branches and leaves and set a movement with a time difference between them and a movement in a different direction. The plant-like object in this case can include a house eave (eave shadow), a wind chime suspended on the eave, and a cloud, a bird, an insect, etc. existing in a natural scenery.

The arrangement of the plant-like object in the window frame can be performed at any position, for example, from the side of the vertically arranged window frame, from below, from above, etc., and either near or away from the screen. For example, the setting can be changed according to the season or the like to change or create an outdoor sign.
The size of the plant-like object is arbitrary. Usually, it is formed of a plate material, but may be formed of a three-dimensional model. The plant-like object is swingably supported directly or indirectly on the window frame. The swing in this case is a concept that also includes vibration in which the position periodically fluctuates around one point.
As for the driving means, when the object is directly driven, there is a case where the object is indirectly driven. In the former case, the tip of the rotating shaft of the motor may be connected to another part using a part of the object as a fulcrum. In the latter case, there is a case where an object which can be swung about the base portion as a fulcrum is pulled by a string, a string or the like to be swung. When an electric fan is used as the driving means, the air flow from the fan can be swung by directly blowing a part or all of the object.
The driving means is not limited to an electric driving means, for example, a motor, a solenoid, a fan, etc., but may be constituted by a mechanical driving means. Examples include mechanical metronomes

The invention according to claim 2 is the pseudo window device according to claim 1, wherein the driving means includes a motor, a solenoid, or a fan for applying an external force to the plant-like object.
Examples of the motor include a pulse motor and a servo motor. The pulse motor (step motor) is driven by applying an external force to the plant-like object regularly, irregularly, or intermittently by a predetermined program stored in a microcomputer control device. Further, when the plant-like object is rocked, the amplitude of the rocking is also adjusted by adjusting the motor output. A pulse motor (stepping motor) can be connected to a part of a plant-like object via, for example, a spring, a string, or the like at an end of a rotating shaft thereof. Various known solenoids and fans can be applied to the solenoid and the fan.

According to a third aspect of the present invention, the driving means includes a string that is connected to the plant-like object at one end and the other end is connected to the window frame, and a vibration applying member that transmits vibration to the string. The pseudo window device according to claim 1, comprising:
As a plant-like object, a bamboo bamboo-like one with branches and leaves growing on the stem can be used. In this case, since the plant-like object was vibrated by giving vibration to the string connected to the stem, the members that give vibration (motor, solenoid, fan, pendulum of the metronome) were changed by changing the set position of the string. It can be arranged at any position. Also, by loosening or strengthening the string, the movement of this plant-like object can be made more or less slow. Therefore, the degree of the outdoor sign can be arbitrarily set. It is also easy to reproduce slight branch and leaf movements. The vibration imparted to the strings can be amplified and transmitted to the branches and leaves (part of the plant-like object).
As the vibration applying member, any of an electric type and a mechanical type can be used. The former includes a pulse motor, and the latter includes a mechanical metronome. Further, in the former, a fan, a solenoid, and the like are also suitable.

The invention according to claim 4 is the pseudo window device according to claim 3, wherein the vibration imparting member includes a mechanical metronome.
By using a solid pendulum, it is possible to give a swing to a plant-like object via a string. Connect or abut the string to the arm of the pendulum with weight. It is also possible to use a simple pendulum instead of the actual pendulum.

  In addition, the above-mentioned swinging includes not only swinging with one point as a fulcrum, but also simple oscillation, tilting and turning in a certain angle range.

  According to the first to fourth aspects of the present invention, the light source is turned on to project the shadow of the plant-like object on the screen. And the function as a pseudo window is exhibited by swinging the plant-like object by the driving means. That is, as a result of the shading of the screen shaking regularly or irregularly, a person staying in the pseudo window installation space can perceive as if it were a window facing the original external space. Therefore, the feeling of staying in the windowless space does not feel stress as a space having windows with external openings. The outside sign can be felt indoors. That is, the indoor atmosphere can be more naturally improved. Further, the connection with the outside world can be more naturally substituted.

  In particular, according to the third aspect of the present invention, the plant-like object is vibrated by applying vibration to a string stretched and connected to the plant-like object. Therefore, it is possible to faithfully reproduce a slight swing and small movement in the plant-like object. The sign of the outdoors (outside the window) can be transmitted well.

  Hereinafter, embodiments of the pseudo window device according to the present invention will be specifically described with reference to the drawings.

1 to 5 show a pseudo window device according to a first embodiment of the present invention. This pseudo window device is configured as a wall-mounted type.
In FIG. 1, reference numeral 1 denotes a picture frame formed of a square plate, and an opening 1A thereof is also rectangular. A rectangular quadrangular window frame 6 is fixed to the rear surface of the frame 1 so as to protrude rearward, and a back plate 7 fixed to the rear end of the window frame 6 forms a box-shaped rear side of the frame 1. Is formed.
The opening 1A of the frame 1 is sealed with a diffusion plate (screen) 2 made of white polycarbonate and having a predetermined thickness. The diffusion plate 2 is a rectangular plate material larger than the opening 1A, and the shadow of one artificial branch (plant-like object) 5 arranged in the box space is projected by the LED light 4 as a light source. The LED light 4 is fixedly arranged inside the back plate 7, and is formed in a single line and extends along the lateral direction of the screen 2.
The artificial branch 5 protrudes substantially horizontally from the side of the screen 2, and its tip extends to the center of the opening 1 </ b> A. The base end of the stem of the plant-like object which is the artificial branch 5 is fixed to a part of the window frame 6 in the space.

  A plant-like object (for example, a plastic branch rod) 5 swingably disposed behind the screen 2 is swingably supported in a vertical plane by a pendulum 3 similar to a metronome. That is, the string 8 having one end (upper end) fixed to the base end side of the stem of the artificial branch 4 is fixed to the tip of the swinging arm of the pendulum 3 at the other end (lower end). The pendulum device 3 constituting the driving means has a certain strength and stroke in the pulling direction with respect to a vertically stretched string 8 (preferably, a transparent and strong wire having a predetermined thickness such as Tegus). Apply external force or release it. As a result, the artificial branch 5 can repeatedly swing up and down with a predetermined amplitude via the string 8. The operation of the pendulum 3 is controlled by a microcomputer control device (not shown). When the CPU executes the program stored in the ROM, the drive control of the pendulum 3 is performed. In this case, the CPU of the microcomputer control device controls ON / OFF of the LED light source 4 and can arbitrarily control the intensity of light from the light source 4.

Next, the operation of the pseudo window device according to this embodiment will be described.
When the pseudo window device is arranged in a predetermined space, for example, on the wall surface of a basement of a building, for example, a hook or the like is attached to the back plate 7, and the pseudo window device such as a picture frame is vertically placed at a predetermined position on the wall surface by the hook. That is, it is fixed parallel to the wall surface. Then, the light source 4 is turned on. As a result, in the rectangular screen 2, one branch 5 (object) extending horizontally from the right side is arranged such that the tip is located at the center of the screen, and the light from the light source 4 The shadow of the object 5 is projected on the center of the screen 2.
When the control device is ON, the swing arm of the pendulum (metronome) 3 swings at a predetermined interval, a predetermined speed, and a predetermined swing width. As a result, the stem (pole) of the branch and leaf 5 is pulled through the string 8 and the branch and leaf fluctuate. The movement of the leaves is projected on the screen 2 as a shadow.
The shaking of the shadow creates an outdoor atmosphere and provides a comfortable space for the occupants.
The movement of the branch 5 is reproduced with respect to the movement of the shadow, but the direction and intensity of the light from the light source 4 can be changed by the control device, and various natural environments can be reproduced as a pseudo window device. It is.

This shows a wall-embedded type of the pseudo window device shown in the first embodiment.
In this configuration, the branch 5 is bent (bent) by the chord 8. The LED light sources 4 are arranged in a matrix. Other configurations are the same as those of the first embodiment, and reference can be made to those of the first embodiment.
In this embodiment, the simulated window device is a buried type with a built-in wall, and the simulated window can be designed in the same shape as a normal window. The control of the swing of the branches and leaves is the same as in the first embodiment.

FIG. 8 shows a driving means of the pseudo window device according to the third embodiment. In this embodiment, the structure of the plant-like object and the string portion, the window frame, the light source, and the screen excluding the driving means are the same as those of the above-described embodiment.
The driving means is configured such that the branch rod 13 is swung by the stepping motor 11 via the drawing wire 12. The branch rod 13 has its base end pivotally supported by a pin (fulcrum) 14 on a part of the window frame. At the base end side of the cantilever-like branch rod 13, a position separated by a predetermined length (a position not reaching the branch) is fixed to the output shaft 11 </ b> A of the stepping motor 11 via the spring 15 and the wire 12. It is connected to a pulley 16. The wire 12 is wound (wound) around the pulley 16 at the end of the motor rotation shaft. A pair of the wire 12 and the spring 15 is provided so as to be vertically symmetrical, and the branch rod 13 is connected between an upper member (part of the window frame) 17 and a pulley 16 so that the wire 12 and the spring 15 are vertically arranged (vertical plane). (Inside).
The microcomputer control device controls the number of rotations and the direction of rotation of the motor to swing the branch pole 13 via the wire 12 and the spring 15. That is, the amount of retraction of the rod 13 is determined in advance by programming in advance, and the number of pulses (the amount of pulses) corresponding to the amount of retraction is given to the driver of the stepping motor 11. As a result, the pulse motor 11 is driven to wind the wire 12 around the pulley 16 by a predetermined amount. The wire rod winds the branch rod 13 downward through the spring 15, and the rod 13 starts swinging. When the winding is completed, the motor 11 is reversed and the wire 12 is pulled out via the spring 15. By repetition of these, the branch rod 13 swings up and down by a predetermined amount at a predetermined speed (every predetermined time). The pair of springs 15 act as a cushion to give a certain time difference to the movement, and also have a pulling action to promote the return of the wire 15 (function as a return spring) when the pulley 16 rotates in the reverse direction.
In addition, the shaking of the branch rod 13 by controlling the light from the light source is the same as that of the above embodiment in that the shading is projected on the screen.
