Description

  The present invention relates to a projector device, and more particularly, to a mounting member for a wall-mounted projector device and a projector device using the same.

  Projector devices, which are projection optical devices that project various types of images, have been widely used as a means for inputting an external image signal and enlarging the image to project it onto a panel, wall surface, etc. Specifically, for example, an enlarged image is projected on a screen or a wall surface while being installed on a desk. However, as already known, for example, as disclosed in Patent Document 1 below, a projector ceiling device for projecting an image on a screen or a wall surface by hanging a projector, which is a projection optical device, on a ceiling is already known. Yes.

  According to Patent Document 2 below, a projection system is also known in which a projector, which is a projection optical device, is suspended from a ceiling and projected onto a cylindrical screen (projection surface).

  In addition, according to the following Patent Documents 3, 4, or 5, there is already known a projector support device that is attached above a wall surface that projects an image and that can adjust the attitude (position and tilt angle) of the projector with high accuracy. Yes.

The structure was not suitable for stably holding the wall.

  Furthermore, the projector support device known from the above-mentioned Patent Documents 4 and 5 has a relatively large structure, and is suitable for use by simply attaching to a wall surface of a general household, for example. However, it did not take into account the uncomfortable feeling and design when the projector device was installed.

  Therefore, the present invention has been achieved in view of the problems in the prior art described above, and in particular, it is relatively easy to attach and use directly on a wall surface for projecting an image, such as in a general household. Provided is a mounting member for a wall-hanging projector device that is possible and does not cause a sense of incongruity on the wall surface of the room even when it is mounted, that is, has an excellent design, and a projector device using the mounting member That is the purpose.

And a wall-mounted projector device having a cover member fixed to the vertical surface, the cover member having a height that covers the outer peripheral side surface of the projector device in the vertical direction. Both of them include exhaust means for releasing the exhaust from the projector apparatus to the outside and means for wiring a cable for supplying driving power and input signals to the projector apparatus. A wall-mounted projector device is provided.

  Further, according to the present invention, a wall-hanging projector main body that projects a part of the optical system from a part to the outside and enlarges and projects a projected image on a vertical surface from a short distance is provided with the vertical projection image projection surface. A mounting member for installation on a surface, the base member being attached to a part of the vertical surface on which the projected image is enlarged and projected, and planted from the base member, A holding member that is fixed to a part and has a leg portion that holds the projector device substantially horizontally; and is disposed so as to surround an outer peripheral side surface of the projector device that is held substantially horizontally by the holding member; and A cover member fixed to the vertical surface, the cover member having a height that covers the outer peripheral side surface of the projector device in the vertical direction, Mounting of a wall-mounted projector apparatus provided with exhaust means for releasing the exhaust from the projector apparatus to the outside and means for wiring a cable for supplying driving power and input signals to the projector apparatus.

It is a figure which compares and demonstrates each embodiment of the cover member of the wall-hanging type projector apparatus which becomes one embodiment of this invention.

  Hereinafter, a wall-hanging projector device and an attachment member using the same according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the same constituent elements are denoted by the same reference numerals, and redundant description is avoided.

  First, FIG. 1 and FIG. 2 are perspective views showing appearances from different angles of a video projection display device which is a main body of a wall-hanging projector device according to the present invention. The main body 1 is fixedly disposed on the upper surface of a lower case 2 (which will be described later in detail) having a substantially rectangular outer shape, in which a bottom surface and four surrounding side surfaces are integrally formed. The upper case 3 is formed.

  As is clear from these drawings, the substantially central portion of the upper case 3 that is the upper surface of the image projection display device is formed so as to rise in a so-called hill shape (convex portion), and a part thereof In other words, the openable mirror cover 31 is separated from other parts and attached to the outside so as to be rotatable by a predetermined angle. In addition, a reflection mirror (free curved mirror) 32 that is a part of the optical system and is formed in a rotationally asymmetric manner is attached to the inside of the openable mirror cover 31 (see FIG. 2). A lens optical system (not shown) is mainly disposed inside the convex portion of the cover portion 3 described above, and an opening 35 for guiding projection light to the outside is formed (FIG. (In FIG. 1, only the last part of the lens optical system is shown through the opening 35). Further, on the surface of the upper case 3, a rotary knob 33 for focus adjustment, a touch panel type operation unit 34 including various input push buttons, and the like are respectively attached.

  In particular, as is apparent from FIG. 2 described above, the image projection display device has one side surface of the lower case 2 having a substantially rectangular outer shape (on the side opposite to the side on which the openable mirror cover 31 is provided). A pair of stand legs 5 and 5 formed integrally with the main body are attached to the side surface so that they can be installed corresponding to the usage pattern of the image projection display device. Further, on the other side surface of the lower case 2, as will be described later, the power supply inlet portion 6 into which the power cable is inserted, for example, when supplying AC power from a commercial power supply to the device, Intake / exhaust port 7 which is an opening for sucking / exhausting air to the outside, and further, although not shown here, for inputting an image projected and displayed by the image projection display device from the outside A terminal board is attached. Also, although not shown, a cooling air intake / exhaust port, and an inclination adjusting leg 8 for adjusting the installation angle of the device are also attached to the bottom surface of the lower case 2.

  In addition, as an example, the external dimensions of the above-described image projection display device are W = 265 mm, D = 200 mm, and H = width = W, depth = D, and height = H indicated by arrows in FIG. It is set to 70 mm and has a dimension corresponding to a so-called A4 size. The weight of the entire apparatus is set to be relatively light, about 1.2 kg. That is, it is designed so that it can be easily installed and projected. Although not shown here, together with a power source and a light source, a modulation unit (for example, a video display element such as a liquid crystal panel) that modulates light from the light source into video light based on a video signal from the outside, and the video Including so-called free-form surface mirrors and free-form surface lenses that can project light with a reduced trapezoidal distortion even from a very short distance (large tilt angle) with respect to the wall surface. A projection optical system is provided.

  Next, FIG. 3 shows a state in which the apparatus is directly attached to a vertical surface (wall surface) that is a surface on which an image is projected using the wall-mounting attachment member according to the present invention. That is, as shown in FIG. 3, in the present invention, the upper and lower main surfaces of the main body 100 of the projector device that is a video projection display device are reversed (that is, the bottom surface 101 is up), and a free-form surface mirror is provided. Installed with the attached windows open (open after installation is complete). More specifically, on the bottom surface 101 of the main body portion 100 of the projector device, a base member 200 constituting the holding means 20 that is a mounting auxiliary member (auxiliary tool) has, for example, a plurality of (four in this example) screws. It is attached by so-called fixing means such as 201.

  In this embodiment, the base member 200 is, for example, a plate-shaped member whose outer shape is formed into a substantially “day” shape by cutting aluminum or punching an iron plate. A plurality of screw holes 202 (four in this example) are formed through and screwed into the screws 201 and the like, and one end (for example, the bottom side) is also made of aluminum or cut or an iron plate. A wall-hanging leg portion 400 having a substantially triangular outer shape cut out by punching is integrally formed. More specifically, the base member 200 has a structure that is planted horizontally from a substantially central portion in the height direction of the leg portion 400. The wall hanging leg 400 uses, for example, screws or the like, although not shown here, with respect to a general wall (that is, a wall surface (vertical surface) 300 on which an image is projected by the projection light from the projector device 100). Accordingly, the projector device 100 is structured to be planted with respect to the wall surface (vertical surface) 300) at a predetermined angle by being attached at a predetermined position. In the figure, through holes 403 through which screws are used are formed in the vicinity of each corner of the triangular member.

  In addition to the holding means 20 including the base member 200 and the legs 400 described above, the mounting member according to the present invention is arranged so as to surround the outer peripheral side surface of the projector device and is fixed to the vertical surface. have. More specifically, in this embodiment, the cover member 50 includes, for example, two plate-like members 51 and 52 in which a semitransparent synthetic resin member is formed in an arc shape, and the two plate-like members. It is composed of a total of three plate-like members, which are plate-like members 53 formed by bending an opaque synthetic resin member arranged in an arc shape. As apparent from FIG. 3, among these three plate-like members, the plate-like member 53 at the center is an arc having a certain distance (curvature radius) from the center assumed to be located inside the wall surface. On the other hand, the two plate-like members 51 and 52 arranged above and below the plate-like member 53 are from the center position, but along an arc having a radius of curvature slightly shorter than the above distance. The three plate-like members 51, 52, 53 are joined to each other by a connecting portion 54. Further, both end portions 55 of these three plate-like members 51, 52, 53 are integrally bent into a “V” shape inside, and a part of the wall portions (screws) are used to make a wall ( When fixing to the (vertical surface) 300, the through-hole 56 for letting the said screw pass is formed.

  Subsequently, FIG. 4 shows a state in which the projector device 100 is directly attached to the holding unit 20 including the base member 200 and the leg 400 described above, and the cover member 50 to the wall surface 300 on which the image is projected. Show. The projector device 100 is arranged so as to stand substantially vertically by the holding means 20, but more strictly, in this example, θ = 91.33 degrees in the figure. That is, the cover member 50 is attached so as to be inclined downward by a slight angle (1.33 degrees) with respect to the leg portion 400.

  FIG. 4 shows a state in which an image is projected from the projector device 100. As apparent from FIG. 4, the image light from the projector device 100 with the mirror cover 31 opened has the projector device 100 on the wall surface 300 and downward from the top to the wall surface (screen). Is remarkably short, in other words, projected at a wide angle and with a predetermined screen size S.

  Further, as is apparent from FIG. 4, the cover member 50 arranged so as to surround the outer peripheral side surface of the projector device has a height “h”) (more strictly, three plate-like members. More preferably, in the present example, the projector device 100 attaches the mirror cover 31 so that the total height of 51, 52, 53 is substantially equal to or greater than the height “H” of the projector device 100. The height is set to be larger than the height in the opened state (that is, the cover member 50 surrounds the outer periphery of the projector device). That is, according to the above-described configuration, the projector device 100 mounted on the wall surface 300 is covered with the cover member 50 in the horizontal direction, so that it can be installed and fixed without causing an uncomfortable feeling on the indoor wall surface. It becomes.

  Further, as indicated by arrows in FIG. 4, the air cooled inside the projector device 100 during operation is discharged from the exhaust port 7, and then the three plate-like members 51 and 52 having different curvature radii from each other. , 53 is exhausted to the outside through the gap. On the other hand, air introduced into the apparatus from the outside is also sucked into the inside through the gap between the three plate-like members 51, 52, 53. That is, the mounting member according to the present invention does not adversely affect the projector device 100 in operation, and moreover, the projector device 100, in particular, a reflection mirror (free-form surface mirror) that reflects image light finally toward the wall surface. ) Since the mirror cover 31 that houses 32 inside is protected from external contact or the like, it is possible to provide a stable operation of the image projection display device.

  Subsequently, further details and modifications of the mounting member according to the present invention described in detail above, in particular, the cover member 50 arranged so as to surround the outer peripheral side surface of the projector device will be described below.

  First, in FIG. 5, a power cable 60 for supplying power from a commercial power source to the projector apparatus 100 and a video signal input cable (for example, a VGA, HDMI (registered trademark) cable, etc.) inside the cover member 50 described above. In this example, so-called cable tables 57 are provided so as to be adjacent to both sides of the projector device. The table 57 is integrally formed on the inner wall surface of one of the two plate-like members 51 and 53 in the upper side and the central portion among the three plate-like members constituting the cover member 50. Or attached. In this example, the upper plate member 51 is integrally formed on the inner wall surface. By utilizing the cover member 50 provided with such a cable table 57, it is possible not only to be conscious of mounting on the wall surface, but also to install a projector device with excellent designability in the room, Further, when the projector device 100 is mounted on the wall surface 300, it is simply placed in the formed wiring space and is not easily recognized from the outside, and a necessary cable (especially when a video signal is transmitted wirelessly). It is possible to wire a power supply cable), and a simple mounting structure is possible.

  FIG. 6 shows a screen size projected onto the wall surface (vertical surface) 300 from the projector device 100 housed therein by attaching the cover member 50 and the base member 200 to the wall surface (vertical surface) 300. It is a figure for demonstrating the relationship with S. FIG. That is, in this embodiment, as is apparent from FIG. 6, the image light (directly projected downward) directly below the reflection mirror (free-form curved mirror) 32 of the above-described mirror cover 31 constituting the projector device 100. 6B and FIG. 6C, a projected image having a screen size S of a substantially square shape (a horizontally long rectangle in this example) with reduced trapezoidal distortion is obtained. In this example, the width of the screen size S obtained by the projection from the projector device is set so as to substantially coincide with the width of the cover member 50 (in this example, slightly larger).

  According to this setting, since the cover member 50 and the projected image are integrally recognized, the design is excellent, and the wall surface (vertical surface) is used with the cover member 50 as a reference when the apparatus is mounted. ) Since the screen size S projected onto 300 can be assumed, the mounting operation is easy.

  6A and 6D, the lower plate-like member 52 of the three plate-like members constituting the lower portion of the cover member 50, for example, the cover member 50 is used. You may form the half-moon shaped collar part 80 in the inner wall surface. That is, when the cover member 50 described above is looked up from below, the collar portion 80 is for hiding the projector device 100 stored therein from the view, and is formed of an opaque or translucent member. It is preferable. However, since the collar 80 may block light projected downward from the projector device 100, it needs to be formed so as not to block the projection light.

  In the embodiment described above, of the three plate-like members constituting the cover member 50, the upper and lower two plate-like members 51 and 52 are formed of a translucent synthetic resin member, and the remaining central portion 1 is formed. Although the sheet-like member 53 is described as being formed of a translucent synthetic resin member, the present invention is not limited to the above-described embodiments, and all of these plate-like members are opaque or semi-transparent. A transparent member may be used, or an opaque and translucent member may be used in appropriate combination.

  Further, as shown in FIG. 7, two plate-like members 51 at the upper part and the center part of the above-described cover member 50, that is, among the three plate-like members constituting the cover member 50, for example. , 53 may be attached to a part of one of the inner wall surfaces as a light emitting means, for example, a plurality of lamps 90 formed of light emitting diodes or the like so as to irradiate illumination light upward. In this example, the lamp 90 as the light emitting means is attached to the upper plate-like member 51. According to such a configuration, when the illumination light from the lamp 80 irradiates the upper part of the cover member 50 softly and softly (see FIGS. 6B and 6C above), the design thereof. It is possible to improve the properties.

  Next, another embodiment of the cover member will be described with reference to FIGS. FIG. 8 is a diagram for explaining another embodiment of the cover member 50a, and FIG. 9 is a diagram for explaining still another embodiment of the cover member 50b. 8 and 9 are the same as FIG. FIG. 10 is a diagram showing an example in which the cover member 50b of still another embodiment shown in FIG. 9 is attached to the kitchen. FIG. 11 is a diagram for comparing the shapes and sizes of the respective embodiments of the cover members 50 to 50b. In the (I) column of the figure, the cover member 50 shown in FIG. 6 is described as a reference. By attaching the cover member 50a and the base member 200 to the wall surface (vertical surface) 300, the screen size S is projected on the wall surface (vertical surface) 300 from the projector device 100 attached to the base member 200 with the bottom surface 101 facing upward. Is projected.

  8A is a top view when the projector device 100 is fixed to the wall surface 300 via the base member 200, FIG. 8B is a front view thereof, and FIG. 8C is a side view thereof. FIG. 8D is a bottom view thereof. Since the projector apparatus 100 is arranged upside down as in FIG. 3, the image light (FIG. 8B) from the reflection mirror (free curved surface mirror) 32 of the mirror cover 31 constituting the projector apparatus 100 obliquely downward. A one-dot chain line in (C) is projected. The positions of the mirror cover 31 and the base member 200 are set so that the projected image light is produced as a projected image having a substantially horizontally long rectangular screen size S with reduced trapezoidal distortion. One of the reasons for providing the cover member 50a is to prevent the projection image light from changing during use of the projector device 100. In addition, the code | symbol 22 in a figure has shown illumination.

  Here, the cover member 50a shown in FIG. 8 is reduced to the minimum size that covers the width in the width direction and the vertical width of the main body of the projector device 100 from the cover member 50 shown in the embodiment of FIG. Are different. The cover member 50 shown in FIG. 6 is suitable for use mainly as a substitute for an exhibition panel or the like for business use. For home use, it is suitable for video display means instead of a large screen television in a relatively wide space such as a living room. In such a case, it is possible to concentrate the line of sight on the projection screen without causing the viewer to feel uncomfortable as the interior of the cover member 50. On the other hand, for example, when the projector device 100 described in this embodiment is attached to a bedroom that is a relatively small space for use at home, the presence of the projector device 100 affects the viewing of the viewer. Therefore, when mounting in a narrow space, it is desirable to reduce the size of the cover member 50a.

  If the cover member 50a is made small, the projection light from the reflection mirror 32 may be partially blocked by the cover member 50a. Therefore, in the present embodiment, the cover member 50a has a shape as shown in the (II) column of FIG. That is, the front side is formed in an arc shape with a small curvature, and both sides are formed so as to be perpendicular to the wall surface 300. The plate-like part 50a1 having a width in the vertical direction is continuous to the upper side of the plate-like part 50a1, and The cover member 50a is composed of a plate-like portion 50a2 having a narrow vertical width formed in an inclined manner and a flange portion 80a that is connected to the lower end of the wide plate-like portion 50a1 and forms a bottom surface portion. On the open end side of the plate-like portion 50 a 1, portions (both end portions) 55 a bent at 90 ° C. are formed, and through holes 56 (not shown) are formed in both end portions 55 a as in the case of the cover member 50. ing. The collar member 80a is formed with a U-shaped notch 80a1 so that the projection light from the reflection mirror 32 is not blocked and the mirror cover is not hindered. A portion other than the U-shaped notch 80a1 of the flange member 80a and close to the plate-like portions 50a1 and 50a2 is provided with the power cable 60 and the video signal input cable 70 as in the embodiment shown in FIG. It is used to hold. In the cover member 50a, the plate-like portions 50a1 and 50a2, the flange member 80a, and both end portions 55a are formed by resin integral molding.

  Since the cover member 50a is reduced in size, the distance between the projector device 100 and the cover member 50a approaches. For this reason, the heat generated in the projector device 100 cannot flow out smoothly from the intake / exhaust port 7 of the projector device 100, and there is a risk that the heat will be trapped. In the projector device 100, since the suction / exhaust ports 7 are provided on the front side and both side surfaces, the U-shaped notch 80a1 formed in the flange member 80a of the cover member 50a is used for exhaust from the front side. Further, an exhaust means (not shown) is provided on the side surface of the plate-like portion 50a1 for intake and exhaust from both sides. Since the cover member 50a of the present embodiment is intended for miniaturization, the length in the left-right direction is shortened, and the power cable 60 and the video signal input cable 70 are attached with the cover member 50a attached. It is difficult to remove. Therefore, it is preferable to form the exhaust means so as to be detachable. As a result, when the cables 60 and 70 are attached or removed, the workability can be improved by removing the exhaust means and working. Further, in the cover member 50a of the present embodiment, a part of the mirror cover 31 protrudes downward in order to reduce the size when the projector device is in use. However, when used in a bedroom or the like, since the viewer is away from the projector device 100, there is little possibility of touching the projector device 100, and the position of the reflection mirror 32 will not be shifted. Moreover, since the intimidation of the projector device 100 is reduced due to the downsizing, the viewer can enjoy comfortable viewing.

  9 and 10 are diagrams illustrating still another embodiment of the cover member 50b. In the present embodiment, unlike the above-described embodiment, an object is placed close to the upper side of the projector device 100 (the projector device 100 itself is placed upside down as described above, so that it is close to the bottom surface 101 side of the projector device). Therefore, it cannot be accessed from the upper surface side. FIG. 10 is an example of a cup board 71 and a sink arranged in a kitchen, for example, and is an example in which the cup board 71 is also arranged on the upper surface side. FIG. 10A is a front view and FIG. 10B is a side view. The wall surface 300 that forms the space in the middle in the vertical direction of the cup board 71 is used as a screen for displaying a cooking recipe or monitoring an image of a security camera attached to the house.

  As shown in the column (III) of FIG. 11, the cover member 50b is connected to the plate-like portion 50b1 whose front side is formed in an arc shape with a small curvature, and the lower end side of the plate-like portion 50b1, and is inclined to the inside. The arc-shaped plate-like portion 50b2, the flange portion 80b having one end connected to the lower end portion of the plate-like portion 50b2 and extending in the lateral direction, the side surface portion 50b4 connected to both side ends of the flange portion 80b, and the side surface portion 50b4 It has both ends 55b bent 90 degrees. The plate-like portions 50b1 and 50b2, the flange portion 80b, the both end portions 55b, and a part of the side surface portion 50b4 are integrally molded with resin. An opening 80b1 is formed at the center of the flange 80b for preventing the projection light of the reflection mirror 32 from being blocked and for operating the mirror cover 31. The vicinity of the side surface portion 50b4 of the flange portion 80b is used for placing and holding the cables 60 and 70.

  Since the cover member 50b shown in the present embodiment can completely cover the projector device 100 in the vertical direction and the horizontal direction, compared to the other embodiments of the cover member 50a shown in FIG. There is room in the width of the left and right and the height in the vertical direction. However, since the upper side of the projector device 100 cannot be used as a work space, the side surface portion of the cover member 50b must be used when the cables 60 and 70 are attached to or removed from the projector device 100. Therefore, a part of the side surface portion 50b4 of the cover member 50b is detachably formed. Here, exhaust means 50b3 is formed in a part of the side surface portion 50b4 that is detachably formed. A number of rectangular holes are formed in the exhaust means 50b3. In order to prevent dust and the like from entering the inside, a hole with a louver may be used instead of the rectangular hole. Removal of the exhaust means 50b3 facilitates the work of the cables 60 and 70.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments are described in detail for the entire apparatus in order to easily understand the present invention, and are not necessarily limited to those having all the configurations described. The apparatus may be installed vertically, and an image may be projected on the information of the apparatus. However, when an image is projected upward, dust or the like is present on the mirror cover 31, the reflection mirror 32, or the like. It is necessary to cover so as not to apply.
