Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a large-screen display system for a home theater or the like, and more particularly to improvement in space saving, effective use of indoor space, ease of use, and comfort.
[0002]
[Prior art]
Conventionally, this type of “storage type home theater system” uses a front projection type projector with a screen size of 60 inches or more when enjoying a home theater on a large screen in a general home. Up to about 50 inches, a plasma display or a rear projection type projector can be used. However, if it exceeds 60 inches, the price increases significantly, and the weight and volume of the display device itself is large, and the indoor space is compressed. It is rarely used in ordinary households. Further, when the size is 70 inches or more, options for the front projection type projector are limited.
[0003]
The present invention has been mainly devised for improving the environment of a home theater system in the front projection type projector. FIG. 20 shows an environment in which a home theater is used by a general front projection type projector. In FIG. 20, the indoor configuration of a conventional front projection type projector is shown by solid lines. There is a screen screen 3 on the wall surface, and video equipment and audio equipment constituting a home theater system are placed on storage furniture 4 below the screen. The illustrated room has a space of 6 tatami mats and shows a state when an 80-inch screen is projected.
[0004]
The projector 31 having the shortest projection distance on the market is installed on a table 33 in the center of the room. On the other hand, the projector 32 has a general projection distance and is placed at the rear end of the room. The current projection distance is the shortest model, and the distance between the screen and the lens is about 1.6 m for an 80-inch screen, and a projection distance of about 2 m is necessary including the projector body. In general models, a distance of about 3 m is required.
[0005]
When enjoying the home theater in this environment, the observer 34 will sit at a position avoiding the optical path of the projector. Alternatively, if the function of correcting the geometric distortion with respect to the oblique projection of the projector is used, the projector can be placed beside the observer, and the observer can sit down and view the image from the front without much concern about the interference with the optical path. You can see. However, in this case, since the image signal processing such as pixel conversion is electrically performed by the geometric distortion correction function, the image projected on the screen surface has a deteriorated resolution. As a method of not deteriorating the resolution and not having to worry about the interference between the optical path and the observer, the projector is installed on the ceiling. However, troublesome work such as the necessity of construction is required. Also, regardless of whether the projector is installed on a table or a ceiling, the projector is connected to a device that is a video signal source by a long cable.
[0006]
On the other hand, in spite of being a front projection type projector, development of a projector using an aspherical mirror has been advanced in order to significantly reduce the projection distance. One example of a system using an aspherical mirror is described in JP-A-2002-82387. In this system example, furniture having a structure capable of storing video equipment and audio equipment constituting a home theater is configured as a cabinet of a projection apparatus provided with an optical system having an aspherical mirror. In addition, the cabinet and screen are integrated, making it a system that can be moved as one set. It is described that when a 16: 9 70-inch screen is mounted, the depth and height of the cabinet size are 36 cm and 42 cm, respectively. As shown in this example, if the projector is of a system that enlarges and projects an image using an aspherical mirror instead of an enlarged projection through a lens as in a conventional front projection type projector, the projection distance is increased while being a front projection type. Extremely short is feasible.

[Problems to be solved by the invention]
There are several problems with a large screen display system such as a home theater constituted by the above-described conventional techniques, methods, and systems. First, a home theater system using a conventional front projection type projector represented by FIG. 20 has the following problems.
(1) Since the projection distance of the projector is long, a large space is required.
(2) Interference between the observer and the optical path is likely to occur, and the viewing position is limited.
(3) When the viewing position is prioritized, image quality deterioration, ceiling installation work, and the like occur.
(4) The cable for signal wiring to the projector is long and obstructive.
(5) Since the projector is installed near the center of the room, the projector cannot be installed, and it takes time to install and clear the projector each time. In addition, in order to make an installation place, it is necessary to remove or bring things in, and in addition, a storage space for the projector is required.
(6) When the projector is installed, it is necessary to adjust the position, size, focus, etc. of the screen every time.
(7) If the projector is installed on the ceiling, it cannot be removed and cannot be moved. Construction and costly.
Further, the system described in JP-A-2002-82387 has the following problems.
(8) The image size is fixed because the projection device itself has an integral structure with a cabinet that is storage furniture and a screen.
(9) If an attempt is made to increase the screen size by removing the integrated screen, the space between the cabinet and the screen increases, which is inconvenient. Alternatively, if the screen size is increased while the screen is integrated, the cabinet size increases.
(10) Since the projection distance is fixed, when the surroundings are bright, the screen size cannot be reduced to increase the luminance.
(11) It cannot be moved to another room due to the large cabinet and integral structure. Thus, the present invention has been conceived to solve these problems. The object of the present invention is to eliminate the trouble of installation and clearing, or to easily view an image from a free position without worrying about interference of an optical path, not to disturb the cable wiring and to change the screen size. An object of the present invention is to provide a large screen home theater system that is extremely space saving. Another object of the present invention is to realize a home theater without oppressing the indoor space, and to provide a comfortable indoor space and environment.
[0009]

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an example of the first embodiment of the present invention. In FIG. 1, a front projection type projector 1 having an aspherical mirror 10 is placed in a drawer portion 2 which is a part of the storage furniture 4, and is stored in a central portion of the storage furniture 4.
[0011]
Here, the projector 1 is a front projection type projector that projects an image enlarged by an aspherical mirror, and has a projection characteristic shown in FIG. FIG. 9 shows the relationship between the distance from the rear end of the projector to the screen surface and the screen size, and the projection angle. The characteristics shown in FIG. 9 are one design example of the optical characteristics of the projector 1, and the specifications of the characteristics can be changed. Therefore, the characteristics of the projector in the present invention are not limited to the characteristics shown in FIG.
[0012]
The size and weight of the projector are about 30 cm in height, 30 cm in depth, less than 40 cm in width, and about 5 kg in weight with the mirror standing up, and the size and weight can be further reduced. In the present embodiment, the storage furniture 4 is fixed and installed in advance on the wall 23, but need not necessarily be mounted on the wall. A screen surface having a space in which an image projected from the projector 1 can be displayed without a break is secured in an upper portion of the storage furniture 4. In the present embodiment, the surface of the wall 23 is used directly as a screen. Here, it is assumed that the surface of the wall as the screen satisfies conditions suitable for projecting an image. The condition of the wall surface required for the screen is that it is white and solid, that it has high diffusivity and that there is little reflection, and that there is no large unevenness on the surface and that there is no warpage or step. Further, storage furniture 5 is disposed on both sides of the screen, and storage furniture 6 is disposed above the screen up to the ceiling surface.
[0013]
In the present embodiment, the home theater system is described using the entire surface of the wall as described above, but it is not always necessary to use the entire wall. However, by using the entire wall to surround the screen surface with storage furniture, if there is external light, the external light can be prevented from entering the screen surface at all to improve the image contrast. Can be.
[0014]
Further, as shown in FIG. 6, the provision of the light-shielding plates 12 and 13 in the storage furniture on the upper and both sides can further improve the contrast. The storage furniture 4 and 5 store therein a video playback device, an audio amplifier, a speaker, and the like necessary for realizing a home theater, and constitute a home theater system.
[0015]
In the home theater system according to the present embodiment, when the home theater is not used, the projector 1 is stored in the furniture 4 as shown in FIGS. The height of the projector 1 is designed such that it can be stored even when the mirror of the projector 1 is open. Next, when using the home theater, the drawer 2 of the storage furniture 4 on which the projector 1 is placed is pulled out. The drawer 2 has a structure that stops at a certain drawer position and does not fall off.
[0016]
The structure of the drawer itself is similar to the structure used for general office desks and furniture. However, a certain degree of high precision is required for the dimensions, processing, etc., so that the left and right hand shake and the up and down hand shake at the time of drawing are minimized. Although it has a certain holding function so that it does not easily move from the position where it has been pulled out and stopped, these methods can be realized by a known method and will not be described. Then, an image is projected on the screen surface 3 by the pulled-out projector. Here, the storage furniture 4 is designed to have a structure and dimensions that do not interfere with the optical path of the projector. In the embodiment of FIG. 1, the screen size is about 85 inches, but the dimensions of the storage furniture 4 are extremely small, about 45 cm in depth and about 45 cm in height. The amount of pulling out of the projector portion is about 40 cm in the depth direction.
[0017]
In the embodiment shown in FIG. 1, the drawer 2 is pulled out, and the image is projected onto the screen surface 3 without being cut off when the drawer 2 is pulled out most, and the lower side of the image is blocked by the storage furniture 4 in the middle position. . Therefore, in the embodiment of FIG. 1, if the projector mirror is stored upright and the drawer 2 is pulled out to the front in use, the focal length, the screen size, and the position are constant, and no adjustment is required in use.
[0018]
Further, since the embodiment uses a screen having an aspect ratio of 4: 3, if the projector is set so that an image of 16: 9 specification is displayed at an upper position on the 4: 3 screen, the 16: 9 screen is displayed. The screen size can be changed by setting the position of the drawer 2.
[0019]
The embodiment of FIG. 1 is characterized in that the depth of the storage furniture can be reduced. However, the screen size cannot be varied structurally as described above. Accordingly, FIGS. 2 and 3 show an embodiment in which the screen size has a degree of freedom. In the embodiment of FIGS. 2 and 3, the height of the storage furniture 4 is reduced and the depth is increased compared to the embodiment of FIG. The structure of the top plate of the storage furniture 4 and the structure of the drawer 2 are changed. The central part of the top surface of the storage furniture 4 is cut out in a rectangular shape as shown in FIGS. 2 and 3, and has a structure in which the slide plate 15 is stored inside. In addition, a rotating plate 16 is provided above the back plate of the drawer 2, and the rotating plate 16 has a mechanism and a structure for rotating 270 degrees. In the embodiment of FIGS. 2 and 3, the projector 1 is stored in the storage furniture 4 even when the mirror 10 is upright. In particular, the slide plate 15 provided on the top plate of the storage furniture 4 is stored in the top plate or on the back surface.
[0020]
The rotating plate 16 provided in the drawer 2 is in an open state, and is placed in a positional relationship parallel to the rear plate of the drawer 2. In this state, since the top plate of the storage furniture 4 is partially open as shown in FIGS. 2C and 3C, the projector 1 is stored without being hit by a mirror. Further, the storage furniture 4 has a cutout structure in which the optical path 7 of the projector 1 projected in the stored state does not interfere with the storage furniture 4.
[0021]
With such a structure, an image is always projected without interruption when the projector 1 moves from the state where the drawer 2 is stored to the state where the drawer 2 is pulled out to the maximum. In the embodiment of FIGS. 2 and 3, the screen size can be varied from about 55 inches to 85 inches or about 100 inches. Further, in a state where the projector 1 is stored with the mirror upright, even if the slide plate 15 is closed, the slide plate 15 does not reach the mirror and the mirror is not damaged. When the mirror 10 is closed and stored, the notch structure portion of the top plate of the storage furniture 4 is closed by closing the rotary plate 16 together with the slide plate 15. Here, the rotating plate 16 has a structure that stops rotating at a horizontal position, and does not drop more than horizontally to the projector side. The size of the storage furniture 2 according to the second embodiment is about 55 cm in depth and about 40 cm in height.
[0022]
Next, the embodiment of FIG. 4 will be described. In the embodiment according to FIG. 4, a drawer 2b is provided in the storage furniture 6 on the ceiling side, and the projector 1 is arranged above. In this case, there is no need to cover the projector as in the case of the storage furniture 4 in the embodiment of FIG. 1, so that the positional relationship in the height direction of the projector can be changed. It can be as short as 40 cm. Since the position of the drawer is high, the drawer 2b is provided with a handle so that the drawer 2b does not become difficult. Further, in the embodiment of FIG. 4, since the optical path 7 of the projector is on the upper side, even if an object is placed in the space on the storage furniture 4 as compared with the embodiments of FIGS. There are benefits too.
[0023]
Next, the embodiment of FIG. 5 will be described. In the embodiment according to FIG. 5, the system is configured as one independent device with minimum dimensions, whereas the system is configured using the entire wall in the previous embodiment, and the system is installed. It is characterized by a very high degree of freedom. The basic structure is such that the portion of the storage furniture 4 in the above-described embodiments of FIGS. 1, 2 and 3 is made independent, but the size of the storage furniture 4 is reduced and the convenience is improved. . Specifically, the height dimension is reduced while keeping the depth dimension of the storage furniture 4 short. The storage furniture 4 is provided with a notch and the drawer 2 is provided with a rotating plate in the same manner as in the embodiment of FIGS. 2 and 3, except that the embodiment of FIGS. In contrast to the structure in which the projector can be projected as it is, the embodiment shown in FIG. 5 aims at the notch only for protecting the mirror when the projector is housed with the mirror upright. Therefore, the user can easily pull out and store the projector, so that it is easy to use.
[0024]
In the embodiment of FIG. 8, the storage furniture 6 on the ceiling side in the embodiment of FIG. 1 is provided with a roll screen and configured to project onto the roll screen. This corresponds to a case where an object is placed on the storage furniture 4 or an object is hung on the wall and cannot be projected on the wall. Since the screen size is reduced because the projection surface is in front, the depth dimension of the lower storage furniture 4 is increased in the embodiment of FIG.
[0025]
As described above, in the example according to the first embodiment, the front projection type projector in which the projection distance is extremely short and the projection angle is high inside the drawer of the storage furniture having the drawer structure in which the video / audio equipment constituting the home theater is stored. The projector is designed so that the projector can be used just by pulling out the drawer, so that the cables connected to each device are not exposed to the outside, and the shadow of the observer does not appear on the screen. The installation is very simple, no installation adjustment is required, and an extremely convenient home theater system can be realized.
[0026]
Further, since the drawer structure is integrated with the projector, the depth of the stored furniture can be reduced, and a very small space-saving home theater system can be realized. For example, a home theater with a screen size of 90 inches (in the case of a 4: 3 aspect ratio) in a space of only three tatami mats can be enjoyed while sitting comfortably.
[0027]
Also, if the storage furniture is separated as one device as in the embodiment of FIG. 5, a home theater system with a high degree of freedom in installation can be realized. Also, as in the embodiment of FIG. 6, by surrounding the screen with storage furniture and providing the storage furniture with a light-shielding plate, the effect of improving the contrast on the screen in an environment where external light is incident on the screen surface can be obtained. Can be
[0028]
Next, an example of the second embodiment of the present invention will be described. FIG. 10 shows a basic structure according to the second embodiment. In FIG. 10, a front projection type projector 1 having an aspherical mirror 10 is installed on a table 51, and the table moves on the floor 8 in a direction perpendicular to the wall 23 of the room. . The projector 1 is stored in the storage section 40 provided on the wall 23 together with the table 51. In the storage state, the opening of the storage section 40 of the wall 23 is covered by the plate provided on the back surface of the placing table 51. A similar flat state results. In the embodiment shown in FIG. 10, when the projector 1 is used, the projector 1 is manually pulled out by a handle structure provided on the rear plate 52 of the stand 51 of the projector. Here, the placing table 51 has a mechanism or a structure that is pulled out perpendicular to the wall surface, and functions in combination with the structure provided in the storage section 40 and the floor 8. This is shown in FIGS.
[0029]
The structural example shown in FIG. 14 is one in which storage and extraction are performed using a telescopic cylindrical shaft 53 used for an antenna or the like. The shaft 53 is housed inside the table 51, and is fixed between the back plate 52 of the table and the inner wall of the storage section 40 of the wall 23 via an appropriate member. In addition, a spherical or wheel-shaped rotating movement assisting mechanism is provided on the bottom surface of the placing table 40 for smooth movement.
[0030]
FIG. 15 shows an example in which another drawer mechanism is used. In FIG. 15, a rail 54 is installed on the floor 8, and the table 51 is provided with wheels 55 for moving on the rail 54. With this structure, the placing table moves along the rail, so that it can always move on a fixed track. In FIG. 15, as an example, a structure of rails and wheels is used. However, the present invention is not limited to this structure, and some tracks installed on the floor in advance and mechanisms and structures that enable movement on the tracks are provided. What is necessary is just to be provided in the base 51.
[0031]
In addition, the drawer mechanism shown in FIGS. 14 and 15 is considered to be fixed at any drawer position and to move for the first time with a certain force or more to prevent the projector position from suddenly moving. It is. Since these mechanisms themselves can be easily realized by existing technology, detailed description will not be given.
[0032]
FIG. 11 shows a state when the projector is used and when the projector is stored. FIG. 11A also shows the use state as viewed from the front, and the relationship between the projected screen size and its position. In the present embodiment, in a room having a ceiling having a height of 2.4 m, a screen size up to about 100 inches can be projected in the case of a 4: 3 aspect ratio. FIG. 11 (B) shows the indoor scene at the time of storage. FIG. 11C shows a state change and a storage structure during use and storage, and the storage unit 40 is provided in a space on the adjacent room side across a wall. On the adjacent room side, a storage shelf 42 having the same depth as the storage section 40 protruding from the wall is installed on the wall, and the storage section 40 of the projector is incorporated in a part of the storage shelf 42. In this way, by integrating with the wall storage furniture and the like in the adjacent room, the portion of the storage section 40 of the projector is erased from the indoor space, and the projector is stored in a form in harmony with the indoor environment of the adjacent room without oppressing the indoor space. I can do it.
[0033]
FIG. 12 shows a specific example in which the projector storage unit 40 is included in the storage shelf in the adjacent room. It can be understood from FIG. 12 that the storage section 40 of the projector is integrated with a part of the storage shelf without any discomfort. The depth of the storage shelf is about 30 cm, which is the same as a normal storage shelf.
[0034]
FIG. 13A shows a structure in which a storage shelf which is opened and closed by a door is arranged in an adjacent room. FIG. 13B illustrates a case where the adjacent room is a mere table or a storage table. The above is the description regarding the basic structure of the second embodiment of the present invention.
[0035]
Next, an example of the home theater system according to the second embodiment will be described. 16 and 17 show an embodiment of a system in which everything can be stored in a wall. In FIGS. 16 and 17, in addition to the projector 1 being housed on the wall as in the embodiments of FIGS. 10 and 12, all the video and audio equipment constituting the home theater system are located in adjacent rooms across the wall. Is stored in a space 45 provided inside the storage shelf 42 of the first embodiment. The storage space 45 is provided at a position where the optical path of the projector 1 does not interfere. 16 and 17, the screen size is about 100 inches. FIG. 17A shows a specific example of the state of the adjacent room, which functions as a storage shelf without discomfort.
[0036]
Next, another embodiment will be described. FIGS. 18 and 19 show a structure and a configuration in which a home theater system can be realized with the same usability as two rooms by providing a storage space for a projector shared by two rooms adjacent to each other with a wall interposed therebetween. . 18 and 19, a common projector storage space 40 is provided between two rooms A and B adjacent to each other with a wall therebetween, and the storage space 40 is included in storage furniture 47 installed on the wall surface of the room B. Have been. Opening and closing doors are provided in both rooms in the storage section of the projector, and the door is opened and the projector is pulled out. The projector is installed on a stand 56, and is installed via a turntable 57 having a mechanism that rotates 180 degrees between them. The turntable 57 has a structure that can be locked at two positions of 0 degree and 180 degrees, respectively. The table has a mechanism or structure that moves along a rail 54 installed on the floor. The rail 54 installed on the floor is installed over two rooms. The storage furniture 47 has a height and a depth that do not block the optical path of the projector. With such a structure and configuration, a home theater can be realized in two rooms with similar convenience. FIGS. 19A and 19B show specific states in which adjacent rooms A and B constitute a home theater system in each room. As described above, in the example according to the second embodiment, the projector is housed inside the wall, and when the projector is pulled out from the wall during use, the projector has a structure that can be pulled out perpendicular to the wall surface. When the projector is not used, the space in the room can be fully utilized, and when the projector is used, the projector can be installed only by a very simple operation.
[0037]
Also, as in the embodiment of FIG. 16, a space for accommodating video and audio equipment is formed in a space of an adjacent room through a wall, and the space is combined with the storage furniture of the adjacent room, so that both indoor spaces are provided. A comfortable environment in which a home theater can be realized without impairment can be realized. Also, as in the embodiment of FIG. 18 and FIG. 19, by adopting a structure and configuration in which the storage space of the projector can be shared by two rooms adjacent to each other with a wall interposed therebetween, a comfortable home theater environment can be realized in two rooms. At the same time, the projector itself can be effectively used.
[0038]
Further, all the embodiments have been described based on the projection specifications of the projector shown in FIG. 9. However, since the design of the projection characteristics shown in FIG. 9 can be changed, the projection distance can be further reduced. By changing the projection angle or changing the projection angle, it is possible to make the home theater system more space-saving and easier to use. However, it should be noted that the shorter the projection distance, the more likely image distortion and resolution degradation depending on the state of the projected wall surface (unevenness, bumps, diffusivity, etc.).
[0039]
【The invention's effect】
As described above, the present invention has the following effects. The first effect is that, despite being a large-screen home theater system using a front-projection type projector that does not require installation work for the projector, there is no need to install and clear the projector, and from any position without worrying about optical path interference. It is possible to realize a home theater system with a large screen in a small space, in which images can be viewed and cable wiring is not in the way. The reason is that the home theater system has a front projection type projector that has an extremely short projection distance and a high projection angle due to an aspherical mirror, and a structure that can utilize the characteristics of this projector to project a large screen onto the screen surface with a minimum depth dimension. The home theater system consists of furniture that can store the necessary video and audio equipment. Another problem is that the projector is arranged in the drawer structure of the storage furniture so that the projector can be used only by pulling out the drawer, so that the optical path does not interfere.
[0040]
The second effect is that a home theater system that can be used as easily as a TV can be realized while having a large screen of 60 to 100 inches, but having a depth equivalent to that of a general audio system or AV system. The reason is that the system according to the present invention allows the front projection type projector to be used without being separated from the furniture in which the projector of the front projection type is stored together with the furniture storing the home theater system, and without having to perform focus adjustment, projection position adjustment, etc. every time. Due to having a structure that can be used. In particular, since the drawer structure allows the projector to appear only at the time of use, the depth of the entire system is extremely small even though the projector is integrated. In addition, the projection light can be enjoyed comfortably without blocking the light. In addition, since the projector has a structure in which the mirror can be stored with the mirror open, it can be used without worrying about the open / closed state of the mirror.
[0041]
A third effect is that a home theater system can be realized without impairing the indoor space at all. The reason is that, as shown in FIGS. 16 and 17, the projector and the video / audio equipment constituting the home theater are housed in the wall, and the projector appears only at the time of use, and the installation work is simplified. It depends on the configuration and structure. Further, since the space in the adjacent room used as a storage space for the projector and other devices is also in harmony with the storage furniture and the like in the adjacent room, the indoor space including the aesthetic appearance is not impaired.
[0042]
A fourth effect is that a home projector system of a stationary type can be realized in two rooms by one projector. The reason is that as shown in FIGS. 18 and 19, a storage space for a projector that can be shared by two rooms adjacent to each other with a wall interposed therebetween is provided, and the projector is moved on a rail set on the floor and both are moved. In each room, the projector can be pulled out from the wall or the furniture to easily enjoy the home theater.
