  An object of the present invention is to provide a cushion and a bed with a projector screen that allow a user lying in a prone state to view a projector image on a large screen.

Projectors have the advantage of being able to view large-size images (moving images and still images) at a low cost compared to direct-view displays, and there has been a system for users lying on their bed in a supine posture. ing.
For example, Patent Document 1 discloses a technique in which light is projected onto a ceiling from a projector placed at the foot of a bed and the ceiling itself is used as a large screen.
Patent Document 2 discloses a technique in which a screen that can stand upright is provided on the foot side of the bed, and light is projected onto the screen from a projector placed on the head side of the bed.

Special Table 2004-516521 Japanese Utility Model Publication No. 5-60353

  However, the above-described conventional technology is a system that allows a user lying on the bed in a posture lying on his back to watch on a large screen, and is not a system intended for a user lying on the bed lying down.

  In view of the above problems, it is an object of the present invention to provide a cushion with a projector screen and a bed using the cushion, in which a user who is lying down can view an image of the projector on a large screen.

The cushion with a projector screen of the present invention is a cushion body part that is hollow and filled with air or light-transmitting fluid inside, a first transmission type screen layer disposed on the cushion body part, and A first reflecting mirror disposed inside the cushion main body and below the first transmission screen layer and reflecting the light projected from the first projector and projecting the light onto the first transmission screen layer; The cushion body portion includes a transparent portion that transmits the light of the first projector, and the user lies face down on the cushion body portion, with the face facing down. is intended to view images projected on the first transmissive screen layer through said cushion main body portion has a shrinkage and flexible, said first Over type screen layer and the first reflecting mirror has flexibility,
It can be rolled or folded .
In addition, an angle adjustment mechanism that changes an inclination angle of the first reflecting mirror with respect to a horizontal plane is provided.

In addition, a portion other than the transparent portion of the cushion main body portion does not transmit light.
Further, the first reflecting mirror can be taken out from the inside of the cushion main body.
Further, the present invention is characterized by further comprising wrinkle prevention means for preventing wrinkles from forming on the first transmissive screen layer.

Moreover, the exoskeleton part surrounding the circumference | surroundings of the said cushion main-body part is provided, It is characterized by the above-mentioned.
Further, the second reflection is disposed inside the cushion main body portion and below the first transmission type screen layer, and reflects light projected from the second projector and projects it onto the first transmission type screen layer. A mirror is provided.
The bed of the present invention includes an opening into which the above-mentioned cushion with a projector screen can be fitted.

In the present invention, the light of the first projector is projected onto the first transmissive screen layer from below and the image is viewed by the user, so that the user lying on his face can view the image of the projector on a large screen. it can.
If the projector is installed on the ceiling so that the optical axis of the projector faces vertically downwards and the surface of the mattress is used as a screen, part of the image may be blocked by the user or a comforter, or the user's shadow may appear in the image. There is a problem of being reflected. There is also a safety problem that the light from the projector directly enters the eyes when the user lies on his back.
In the present invention, this problem is solved by projecting light from the projector from below to above on a transmission screen.

In addition, when projecting light from the first projector from below to above, a method of installing the projector so that the optical axis of the projector is vertically upward in the space under the bed is conceivable. However, in order to display an image on a large screen, it is necessary to increase the distance from the screen to the projector to some extent. When the projector is installed vertically under the bed, there is a problem that the distance cannot be sufficiently secured. In addition, it is necessary to prepare a projector that supports such vertical installation, and there is a problem that the degree of freedom in selecting a projector is limited.
In the present invention, this problem is solved by using the first reflecting mirror to reflect the light of the first projector from the horizontal direction upward in the vertical direction. Further, since the size of the image can be controlled by changing the distance from the first reflecting mirror to the first projector, the image can be adjusted to the size of the first transmissive screen layer.
In addition, the large screen image projected on the first transmissive screen layer will be viewed through the air, water, gel, etc. in the cushion body, and the user will be able to experience a unique feeling of floating and presence, so that it can be used for games. Is suitable.
In addition, due to Pascal's principle, the pressure generated by the user's body weight is distributed and applied to each surface constituting the outer shell of the cushion body through fluid such as air and water in the cushion body (FIG. 1). (Refer to the arrow inside the cushion body 10 in (a)). Thereby, the flatness of each surface constituting the cushion main body portion is maintained, and wrinkles are less likely to occur in the first transmission type screen layer.
In addition, since it can be viewed while lying on the bed, it is also suitable for nursing care for patients who have difficulty lying on their back due to back pain or the like.

By changing the tilt angle of the first reflector using the angle adjustment mechanism, the degree of freedom of the installation position of the first projector can be increased, and the position of the image on the first transmission type screen layer can be changed. .
By providing the cushion body with shrinkage and flexibility, and providing flexibility to the first transmissive screen layer and the first reflector, the cushion with the projector screen can be rolled or folded and easily carried. It becomes like this. It can also contribute to weight reduction of the projector screen cushion.

If the cushion body does not transmit any light other than the transparent part, the light reflected by the first reflector will not leak to the outside of the cushion body, causing inconvenience to surrounding third parties. Disappears. In addition, since light other than the light projected from the first projector does not enter the first reflecting mirror, the user can see a clear image.
If the first reflecting mirror can be taken out from the inside of the cushion main body, the cushion main body with the first reflecting mirror extracted can be contracted and easily carried. Also, it is excellent in maintainability when the first reflecting mirror is dirty or damaged.
By providing wrinkle prevention means for preventing wrinkles from forming on the first transmissive screen layer, the user can see a clear image.

By providing an exoskeleton that surrounds the periphery of the cushion body, the amount of deflection of the cushion body can be suppressed, the posture of the prone user can be stabilized, and the first transmission type screen layer is generated. Can suppress wrinkles.
By providing a second reflecting mirror that reflects the light projected from the second projector and projects it onto the first transmissive screen layer, the user can view both the image of the first projector and the image of the second projector. it can. When adjusting the image of the first projector and the image of the second projector to be one large image, the distance from the floor surface to the first transmissive screen layer can be shortened, so a cushion with a projector screen Can be suppressed.
By providing an opening in which a cushion with a projector screen can be fitted in the bed, the user can view a large screen image while lying on the bed, and can also sleep as it is when not in use.

[First embodiment]
Hereinafter, a first embodiment of a cushion with a projector screen of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the user U lies on the cushion 1 with the projector screen in a face-down state with the face facing down, and the light projected from the first projector P1 is reflected by the first reflecting mirror 30 to be the first A large screen image is viewed by copying it on the transmissive screen layer 20.

The projector screen-equipped cushion 1 is generally composed of a cushion main body 10, a first transmission screen layer 20, a first reflecting mirror 30, and an angle adjusting mechanism 40.
The cushion body 10 is hollow and is filled with air or light-transmitting fluid 11 inside. As a material of the cushion portion, for example, a material having transparency and flexibility such as soft vinyl chloride is preferable, but not necessarily limited thereto.
Air or light permeable fluid 11 is filled into the cushion body 10 through the inlet 12. Examples of the light-transmitting fluid 11 include, but are not limited to, a transparent liquid such as water and a substance such as a gel having transparency.
In the present embodiment, the shape of the cushion main body 10 is a rectangular parallelepiped, but other shapes such as a columnar shape, a cross-section kamaboko shape, a cross-sectional meniscus shape, and the like may also be used. The size of the cushion body 10 is preferably provided with a length and a width so that the user U can lie down on the top.

The first transmission type screen layer 20 is disposed on the upper part of the cushion body 10, and the light of the first projector P1 is projected. Since the first transmissive screen layer 20 may be a known transmissive screen, description of the material and properties thereof is omitted.
As a method of fixing the first transmission type screen layer 20, for example, as shown in FIG. 2, a method of inserting the end of the first transmission type screen layer 20 into a pocket 21 disposed outside the upper surface of the cushion body 10, Examples thereof include a method of detachably fixing by a known means such as a fastener, a fastener and a hook, and a method of fixing with an adhesive. As shown in FIG. 3, the first transmission type screen layer 20 may be fixed inside the upper surface of the cushion body 10.
Further, as shown in FIG. 4 (a), a transparent plate 51 may be interposed between the lower surface (or the upper surface) of the first transmission type screen layer 20 as the wrinkle prevention means 50. The transparent plate 51 may be made of a transparent material such as tempered glass, transmissive plastic, and acrylic. Furthermore, as shown in FIG. 4B, by attaching the transparent plate 51 to the side surface of the cushion main body portion 10 where light from the first projector P1 passes, it is possible to prevent wrinkles from occurring at the location. As shown in FIG. 5, the transparent plate 51 may be inserted into the pocket 52, fixed detachably by a known means such as a hook-and-loop fastener, or fixed with an adhesive.

The first reflecting mirror 30 is disposed inside the cushion body 10 and below the first transmissive screen layer 20, and reflects the light from the first projector P1 and projects it onto the first transmissive screen layer 20. Provided for. In the present embodiment, a general mirror that is flat and has little flexibility is used as the first reflecting mirror 30.
The angle adjusting mechanism 40 is provided to change the inclination angle of the first reflecting mirror 30 with respect to the horizontal plane, and is attached to the lower part of the first reflecting mirror 30 in the present embodiment. Specifically, the angle adjustment mechanism includes a connecting portion 41 and a leg portion 42, and has a structure that is rotatable about a pivot support location by pivotally supporting the connecting portion 41 on the leg portion 42. By fixing the connecting part 41 to the lower part of the first reflecting mirror 30 and fixing the leg part 42 to the bottom surface of the cushion main body part 10, the first reflecting mirror 30 can be rotated in the vertical plane, thereby the first reflecting mirror. The inclination angle with respect to 30 horizontal planes can be changed.
When projecting light in a state where the optical axis of the first projector P1 is parallel to the horizontal plane, the inclination angle of the first reflecting mirror 30 with respect to the horizontal plane is preferably 45 degrees. By setting the inclination angle to 45 degrees, the light reflected by the first reflecting mirror 30 can be made to enter the first transmissive screen layer 20 perpendicularly, and distortion of the projected image can be suppressed as much as possible. In addition, instead of adjusting the tilt angle, the keystone correction function (which is installed in almost all projectors on the market) that suppresses the distortion mounted on the first projector P1 reduces distortion. May be. Note that the light of the first projector P1 needs to be inverted and projected as necessary.

The angle adjusting mechanism 40 may employ any of the configurations shown in FIGS.
The angle adjustment mechanism shown in FIG. 6 includes a flexible backing material 43 to be attached to the back surface of the first reflecting mirror 30 (the surface without the reflecting surface), a chain 44 attached to the lower portion of the first reflecting mirror 30, and a cushion body. The hook 45 is attached to a part of the inner surface of the portion 10. The upper side of the backing material 43 is fixed inside the upper surface of the cushion body 10 (a portion surrounded by a broken circle in the figure), and the first reflector 30 is vertically centered around the fixed portion. It is supported so that it can rotate in the plane. The user U grasps the chain 44 from the outside of the cushion main body 10 and hooks it on the hook 45 in a state where the cushion main body 10 is slightly contracted by slightly removing air or the like inside the cushion main body 10. The inclination angle of the first reflecting mirror 30 can be changed depending on the position at which the hook 45 is hooked on the chain 44.
The angle adjusting mechanism of FIG. 7 differs from the angle adjusting mechanism of FIG. 6 in that a string 46 and a plug 47 are used instead of the chain 44 and the hook 45. Specifically, one end of the string 46 is attached to the lower part of the first reflecting mirror 30, and the other end is attached to the periphery of the shaft portion 47a of the plug 47. A head 47b of the plug 47 is exposed to the outside through an opening 13 provided on the side surface of the cushion body 10. The opening 13 is tightened from above the shaft 47a with an O-ring, rubber packing 48, or the like, so that air inside the cushion body 10 does not leak out. When the user U turns the head 47b around the axis and wraps the string 46 around the shaft 47a, the lower part of the first reflecting mirror 30 is pulled in the direction of the shaft 47a, thereby tilting the first reflecting mirror 30. You can change the corner.
The angle adjustment mechanism in FIG. 8 differs from the angle adjustment mechanism in FIG. 7 in that an expansion portion 49 is used instead of the stopper 47. Specifically, the other end of the string 46 is attached to the upper end of the inflating portion 49. When the user U introduces air or the like into the inflating part 49 through the inlet 49a, the volume of the inflating part 49 increases, and the lower part of the first reflecting mirror 30 is pulled upward along with this. 1 The inclination angle of the reflecting mirror 30 can be changed.
The cushion 1 with a projector screen may be configured not to include the angle adjustment mechanism 40.

The cushion body 10 includes a transparent portion 14 (see FIG. 1 (a)) at least partially. The light projected from the first projector P1 disposed outside the cushion main body 10 passes through the transparent portion 14 and is reflected by the first reflecting mirror 30 disposed in the cushion main body 10 to be reflected by the first transmission type screen layer 20. To. In other words, the surface constituting the outer shell of the cushion body 10 and the optical path from the first projector P1 to the first reflecting mirror 30 and the optical path from the first reflecting mirror 30 to the first transmission screen layer 20 The transparent portion 14 is provided at the overlapping portion.
The transparent portion 14 may be made of a transparent material such as a resin such as soft vinyl chloride or glass, but the transparent portion 14 is used when the cushion body portion 10 is made to have shrinkability and flexibility as described later. Is preferably made of a resin such as soft vinyl chloride.

As shown in FIG. 9, a portion other than the transparent portion 14 of the cushion main body 10 may be configured not to transmit light. Specifically, a light non-transparent film S is attached to a portion other than the transparent portion 14 of the cushion main body 10, or a light non-transparent material is applied, or the portion itself is made light non-transparent. What is necessary is just to manufacture with a material. Thereby, the diffusion of the light L1 directed from the inside to the outside of the cushion main body 10 can be suppressed, and the third person X other than the user U can be prevented from feeling unpleasant. Further, since the stray light L2 entering from the outside to the inside of the cushion main body 10 coming out of the first projector P1 or the like is reduced, the user U can clearly see the image of the first projector P1.
As shown in FIG. 10, an exoskeleton 60 surrounding the cushion body 10 may be provided. Specifically, the weight of the user U can be obtained by inserting a square frame-shaped member from the front and rear (FIGS. 10 (a) and (b)) or the left and right (FIGS. 10 (c) and (d)) of the cushion body 10. It is possible to prevent deformation of the cushion main body 10 due to the above, etc., to stabilize the posture of the user U in the prone state, and to prevent defects such as wrinkles in the first transmission type screen layer 20.

In addition, as shown in FIG. 11, the cushion main body 10 may be provided with contractility and flexibility, and the transmission screen layer and the first reflecting mirror 30 may be provided with flexibility. In this case, since the cushion 1 with a projector screen can be contracted and rolled or folded, the portability is improved (see FIGS. 1 (c), 11 (c) and 11 (d)).
Further, in the configuration of FIG. 11, as shown in FIG. 12, a slit 15 extending obliquely downward from the upper surface of the cushion body 10 may be provided. In this case, the first reflecting mirror 30 does not need to have flexibility, and a general mirror having a flat shape and hardly having flexibility can be used as the first reflecting mirror 30. The first reflecting mirror 30 can be held in an inclined state with respect to the horizontal plane by inserting the first reflecting mirror 30 into the slit 15 when in use, and the first reflecting mirror 30 is taken out from the slit 15 and cushioned when not in use. The main body 10 can be rolled or folded. Further, it is excellent in maintainability when the first reflecting mirror 30 is dirty or damaged. The inclination angle of the first reflecting mirror 30 can be adjusted by adjusting the amount of air or the like that fills the cushion body 10. Further, as shown in FIG. 13, the inside may be divided into two sections A and B by a slit 15a provided in the cushion body 10. In this case, the inclination angle of the first reflecting mirror 30 can be adjusted more accurately by adjusting the filling amount of air or the like in each of the sections A and B.

Specifically, the second reflecting mirror 31 is disposed inside the cushion main body 10 and below the first transmissive screen layer 20. Further, the second reflecting mirror 31 reflects the light of the second projector P2 disposed outside the cushion main body 10 and projects it onto the first transmissive screen layer 20. The optical axis of the first projector P1 and the optical axis of the second projector P2 are preferably arranged to face each other along the same straight line. Then, the image from the first projector P1 is, for example, the right half of the whole image, and the image from the second projector P2 is the left half of the whole image, so that the first transmissive screen layer is reflected by the first reflecting mirror 30. The image projected onto 20 and the image reflected on the second reflecting mirror 31 and projected onto the first transmissive screen layer 20 can be combined into a single large screen image.
With such a configuration, compared to the configuration of only the first reflecting mirror 30 shown in the first embodiment, the first reflecting mirror 30 and the second reflecting mirror 31 to the first transmission type screen layer 20 The distance can be shortened, and the height of the cushion 2 with the projector screen can be suppressed.
