Description

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

A projector device, which is an optical device that projects various types of images, has been widely used as a means for inputting an image signal from the outside, enlarging the image, and projecting the image onto a panel, a wall surface, or the like, and is generally used. For example, an enlarged image is projected on a screen or a wall surface while being installed on a desk or the like. For example, in the following Patent Document 1, a projector which is a projection optical device is installed on a desk or hung from a ceiling to project an image on a screen or a wall surface, and in the following Patent Document 2, , A projection system in which a projector, which is a projection optical device, is suspended from a ceiling surface and projected onto a cylindrical screen (projection surface) surrounding the viewer is also already known.

In addition, according to the following Patent Document 3, a projector support device that can be mounted above a wall surface on which an image is projected and can adjust the posture (position and tilt angle) of the projector with high accuracy is already known.

In recent projection optical devices, in particular, various improvements in the projection lens system including a free-form surface mirror and a free-form surface lens have made it possible to obtain a projection image with reduced trapezoidal distortion despite a large inclination of the image light. An ultra-short type in which the distance from the projection optical device to the wall surface (screen) on which the image is projected is remarkably shortened is already known.

Therefore, instead of the support structure in which the projector known in Patent Documents 1 and 2 is suspended from the ceiling, the projection optical device as known in Patent Documents 3 and 4, that is, the wall surface on which the image is projected is directly projected.

However, in the above-mentioned prior art, in particular, the support structure on the projection surface (wall surface) of the projector device according to Patent Document 3 is a hanging member (string, wire, rope, etc.) fixed to the wall surface. Since the projector device is suspended and supported by wire rods, chains, or strips), the force (contact force) that presses the projector device against the wall surface separates the gravity on the device in the horizontal direction. The structure was not suitable for stably holding the device against the wall surface.

In particular, a so-called ultra-short projection type projector device having a very short projection distance is suitable for a wall-mounted type used by mounting it on a wall surface, but on the other hand, due to the short projection distance, the installation position of the device is Since the position and shape of the projected image on the wall surface will change even with a slight movement (deviation) or tilt, the mounting member that mounts the projector device on the wall surface can finely adjust the movement (deviation) and tilt. Is required to be.

Therefore, the present invention can be used by being directly and relatively easily attached to a wall surface such as an indoor room of an ordinary household, and even after the attachment work to the wall surface, the fine position of the projector device and the fine position of the projector device can be obtained.

A luminaire comprising a mounting member, the mounting member is provided by a luminaire capable of adjusting the luminaire body around three axes orthogonal to each other in a space in which the luminaire is held. Will be done.

Then, according to the present invention, it is a mounting member for installing a projector device main body or a lighting device that magnifies and projects an image or illumination light from a short distance onto a vertical surface with respect to the vertical surface which is a projection surface of the image.

In the following description, the same configuration requirements will be indicated with the same reference numbers, and duplicate explanations will be avoided.

First, FIG. 1 shows a wall-mounted projector device (main body) 1 according to the present invention together with a mounting member 50, and FIG. 2 shows a state in which the projector device is mounted on a wall surface 60 of a room in particular. In this figure, the projector device is arranged so as to surround the outer periphery thereof, and is arranged inside a decorative cover member 70 fixed to a wall surface. As is clear from these figures, the image light L projected from the projector device (main body) 1 is projected onto the wall surface 60 to which the device is attached, and the desired image screen IM is displayed on the surface. The Rukoto.

In the above example, the projector device (main body) 1 is arranged so as to project the image light downward, but the present invention is not limited to this, and the projector device (main body) is not limited to this. ) May be arranged so as to project the image light upward. Further, the cover member 70 arranged so as to surround the outer periphery of the projector device (main body) is, for example, a translucent synthetic resin member, an opaque synthetic resin member, glass, metal, or other material curved in an arc shape. A plurality of plate-shaped members formed in the above manner may be combined and attached to the projector device (main body), or individually attached to the wall surface 60.

Subsequently, as shown in FIG. 1, the wall-mounted projector device (main body) 1 is fixed at a predetermined position on the wall surface 60 in a state of being fixed by the mounting member 50 including the wall fixing bracket 510 and the projector fixing bracket 520. It is attached to and fixed to.

Here, an example of the wall-mounted projector device (main body) 1 will be described below prior to explaining the specific configuration of the mounting member 50 described above.

As the wall-mounted projector device (main body) 1, in this example, a relatively small and lightweight projector device that can be used even when placed on a desk is used, and an example thereof is shown below.

<Projector device (main unit)>
As shown in FIGS. 3A and 3B, the projector device (main body) 1 of this example has a bottom surface and four peripheral side surfaces integrally formed, and has a substantially rectangular outer shape. It is configured to be housed inside a space formed by a side case 2 and an upper case 3 arranged and fixed on the upper surface thereof. It should be noted that these figures are perspective views showing the appearance of the device as viewed from different angles.

Further, as is clear from these figures, the substantially central portion of the upper case 3, which is the upper surface of the projector device, is formed in a so-called hilly shape (convex portion), and a part thereof, that is, The openable / closable mirror cover 31 is separated from other parts and is rotatably attached to the outside by a predetermined angle. A reflective mirror (free-form surface mirror) 32, which is a part of the optical system and is formed in a convex shape and rotationally asymmetrically, is attached to the inside of the openable / closable mirror cover 31. Further, inside the convex portion of the cover portion 3 described above, a lens optical system (not shown here) is mainly arranged, and an opening 35 for guiding the projected light to the outside is formed. Further, on the surface of the upper case 3, a rotary knob 33 for adjusting the focus, a touch panel type operation unit 34, and the like are provided, respectively.

Further, a pair of stand legs 5 and 5 integrally formed with the main body are attached to one side surface of the lower case 2 of the projector device so that the projector device can be installed vertically according to the usage pattern of the device. ing. Further, as will be described later, on the other side surface of the lower case 2, the power inlet portion 6 into which the power cable is inserted, such as when supplying AC power from a commercial power source to the device, and the internal cooling are further provided. An intake / exhaust port 7 which is an opening for sucking / exhausting air to the outside, and a terminal plate for inputting an image projected and displayed by the device from the outside, which is not shown here. Is installed. Further, although not shown, an intake / exhaust port for cooling air 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, mounting means (screw holes 36 in this example) for mounting the projector fixing bracket 520 of the mounting member 50 described below is formed on one side surface of the lower case 2 (see FIG. 5). ).

In addition, as an example of the external dimensions of the projector device described above, the width = W, depth = D, and height = H indicated by the arrows in FIG. 3 are W = 265 mm, D = 200 mm, and H = 70 mm, respectively. It is set and has dimensions corresponding to the so-called A4 size. The weight of the device as a whole 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, a modulation unit (for example, a video display element such as a liquid crystal panel) that modulates the light from the light source into video light based on a video signal from the outside, and the video, together with a power supply and a light source. Includes so-called free-curved mirrors and free-curved lenses that can project light onto a wall surface with reduced trapezoidal distortion even from a very short distance (large tilt angle), thus providing excellent projected images. It is equipped with a projection optical system.

Further, FIG. 4 is a cross-sectional view showing an example of the configuration of the above-mentioned optical system. For example, light from a light source made of a semiconductor laser or the like (not shown here) is, for example, DLP (Digital Light Processing) (registered) according to an external video signal (for example, a video signal from a mobile terminal, tablet, or PC). Modulation is performed by a reflection type optical modulator 100 including a micromirror or a reflective liquid crystal panel (LCOS (registered trademark): Liquid crystal on silicon) such as the device 1 or a transmission type optical modulator 100 composed of a liquid crystal panel or the like. The image obtained thereby is synthesized by the prism 101, projected onto the reflection mirror 32 via the projection lens system 102 composed of a plurality of lenses, reflected on the surface thereof, and magnified and projected. The projection lens system 102 composed of the plurality of lenses described above is a free-form surface that is not rotationally symmetric and is necessary for correcting various distortions associated with magnified projection of an image, such as distortion due to oblique incidence and trapezoidal distortion. It includes various lenses including shape lenses and the like. Further, the projection lens system 102 is movably mounted on the projection lens base 103, and by the action of the lens adjustment mechanism 104 in the figure, a part of the lenses or lens groups of the projection lens is moved in the vertical direction in the figure. The focus can be adjusted.

Further, in this figure, the light is magnified by the above-mentioned optical system and projected onto the reflection mirror 32 (see the broken line in the figure), and then reflected on the surface thereof, for example, a screen, a wall surface, a desk, a table, or the like. The upper limit light LU and the lower limit light LD of the image light projected on the surface to be projected are indicated by arrows in the figure.

By adopting an optical system including a projection lens system 102 including a free-curved lens as the reflection mirror 32, a sufficiently enlarged image is projected and displayed even if the distance from the device to the image projection surface is short. It ensures the excellent projection performance possible (so-called ultra-short projection type projector device). Specifically, when the image is projected in a state where the tip of the device is in contact with the image projection surface, the screen size is 30.5 inches x 19.1 inches (36 inches diagonal screen size 16:). I was able to obtain the screen of 10).

<Mounting member with 3-axis adjustment function>
FIG. 5 is a perspective view showing the wall fixing bracket 510 for fixing the above-mentioned mounting member 50 and the projector fixing bracket 520 in an exploded manner. As is clear from the figure, the wall fixing bracket 510 is easily formed by machining a metal plate such as iron or aluminum by machining such as pressing. Further, the rigidity is increased by providing a flange portion or the like around the wall fixing bracket 510, and the outer shape is formed into a substantially triangular shape. Further, wall surface fixing portions 511 (including, for example, screw holes for fixing) are formed on both sides of the triangular side, and a three-axis adjusting mechanism described in detail below is formed near the top thereof. The hemispherical shaft 512 is fixed.

On the other hand, the projector fixing bracket 520 extends along one side of the substantially rectangular outer shape of the projector fixing portion 521, which is attached to the bottom surface of the projector device (main body) 1 by a metal plate or the like together with the flange portion or the like. It is composed of an extension portion 522 formed of the above and connected to the fixing member 521. Further, at a position close to the substantially central portion of the side of the projector fixing portion 520 opposite to the extension portion 522, an elastic member is used together with a spherical bearing 523 that receives the hemispherical shaft 512 on the wall fixing bracket 510 side. A certain adjusting spring 551 is provided in parallel in the vicinity of the hemispherical shaft 512. In addition, the extension portion 522 is provided with adjusting springs, which are elastic members, at a central portion thereof and at positions close to both end portions thereof. Here, these adjusting springs are indicated by different reference numerals 551, 552, 554, and 554 corresponding to their positions, respectively.

More specifically, as shown by the alternate long and short dash line in the figure, the projector fixing portion 521 is fixed to the bottom surface of the projector device (main body) 1 by fixing members 560 such as four screws. Further, the projector fixing portion 521 is attached to the lower surface of the wall fixing bracket 51 by the plurality of (four in this example) adjusting springs 551 to 554 described above (specifically, the hooks at both ends of the spring 550 are attached to each of them. It is hooked on slits, fixing bolts, pins, etc. formed in the fixing brackets 510 and 520).

In addition, in the figure, three adjustment dials (adjustment dial 1, adjustment dial 2, adjustment dial 3) are shown by reference numerals 70, 80, 90, and these adjustment dials are as is clear from the figure. , Each of the wall fixing metal fittings 510 is movably attached along a predetermined direction (specifically, the wall fixing metal fittings 510 are screwed into a screw groove formed in advance and inserted). The adjustment dials 70 and 80 and the adjustment springs 552 and 535 are attached to the vicinity of the apex on the bottom side of the triangle facing the hemispherical shaft 512 attached to the apex of the wall fixing bracket 510 in the shape of a substantially triangular shape. .. The adjustment dial 90 is attached in a direction orthogonal to the vicinity of the adjustment dial 70 (80). The adjusting spring 554 is attached in the direction orthogonal to the same straight line of the adjusting springs 552 and 535.

With the above configuration, the projector fixing bracket 520 and the projector main body 1 are always pulled by the wall fixing bracket 520 due to the tension (contraction force) of the adjusting spring. The adjustment dials 70, 80, and 90 ensure a certain distance from the wall fixing bracket 520 and maintain a stable posture.

According to the structure of the mounting member 50 described above, the wall fixing bracket 510 and the projector fixing bracket 520 are separated by a predetermined distance by the hemispherical shaft 511 and the hemispherical bearing 523, and a plurality of adjusting springs 551 to 554 which are elastic members are separated from each other by a predetermined distance. They are rotatably connected to each other using the tension (contraction force) of. From this, by applying a force against the contraction force, the positions of each other are changed, that is, the projector device (main body) 1 is fixed to the wall fixing bracket 510 fixed to the wall surface 60. The projector fixing bracket 520 can be freely adjusted in the three-axis directions as described below. Here, the mounting member 50 realizes a three-axis adjustment function by using the three adjustment dials (adjustment dial 1, adjustment dial 2, and adjustment dial 3) described above. The details will be described below.

FIG. 6A shows a hemispherical shaft 511 fixed near the triangular top of the wall fixing bracket 510 and one side of the projector fixing bracket 520 (extension portion 522) among the mounting members 50 described above. FIG. 5 is an enlarged cross-sectional view showing a hemispherical bearing 523 fixed to a substantially central portion of (opposite side) as a center. As is clear from this figure, the projector fixing bracket 520 is in contact with the wall fixing bracket 510 at a predetermined distance due to the contraction force of the adjusting spring 551 and the hemispherical shaft 512 and the hemispherical bearing 523. It is connected while maintaining the above, and by the action of the spherical shaft 512 and the spherical bearing 523, it is rotatable with respect to the wall fixing bracket 510.

Further, as shown in FIG. 6B, the upper surface portion of the hemispherical bearing 523 is lower than the hemispherical shaft and the spherical center of the hemispherical bearing by h, and as shown in FIG. 6C, Even if the projector fixing bracket 520 is tilted α with respect to the wall fixing bracket 510, the cylindrical portion of the hemispherical shaft and the hemispherical bearing do not interfere with each other.

FIG. 7 is an enlarged cross-sectional view centering on the adjustment dial 1-70 or the adjustment dial 2-80 among the three adjustment dials described above. As is clear from this figure, as the adjustment spring 550 contracts, the tip of the adjustment dial 1-70 and / and the adjustment dial 2-80 are pressed against the surface of the projector fixing bracket 520. On the other hand, the projector fixing bracket 520 is connected to the wall fixing bracket 510 while maintaining a predetermined distance, but the adjustment dial 1-70 and / and the adjusting dial 2-80 attached to the wall fixing bracket 510 are connected. By rotating, it moves in the vertical direction in FIG. 7. As a result, the inclination of the projector fixing bracket 520 can be adjusted with respect to the wall fixing bracket 510 with the hemispherical shaft / bearing as a fulcrum.

FIG. 8 is an enlarged cross-sectional view centered on the adjustment dial 3-90. As is clear from this figure, the adjustment dial 3-90 is a flange portion extending in the vertical direction from the inclined portion (specifically, the side extending along the slope of the triangle) of the wall fixing bracket 510 having a substantially triangular shape. ), And its tip is tilted and in contact with a part of the projector fixing bracket 520. As a result, the adjustment dial 3-90 is rotated to move in the direction indicated by the arrow, and the projector fixing bracket 520 rotates in the direction indicated by the broken line arrow with the hemispherical shaft / bearing as the fulcrum with respect to the wall fixing bracket 510. It becomes possible to move.

Note that FIG. 9 typically shows the adjustment dial 1-70 among the above-mentioned adjustment dials, and as is clear from the figure, has a shaft-shaped threaded portion 71 at one end thereof. Formed / fixed the hemispherical portion 72, and at the other end, a disk-shaped operating portion 73 having a plurality of grooves formed in the axial direction was integrally attached to the peripheral surface thereof in order to perform a rotation operation. Has been done.

Subsequently, the adjustment on the three axes (X-axis, Y-axis, Z-axis) of the projection screen by the above-mentioned three adjustment dials will be described in detail below.

10 (a) and 10 (b) show the direction of rotation about the X-axis in the figure by rotating the adjustment dial-1 and the adjustment dial-2 among the three adjustment dials described above (FIG. 10 (a) and (b)). The adjustment in (indicated by the arrow) is shown. That is, by rotating the adjustment dial 1-70 and the adjustment dial 2-80 shown in FIG. 10 (a), the projector device (main body) 1 fixed to the projector fixing bracket 520 is moved as shown in FIG. 10 (b). By moving within the range, it is possible to adjust the rotation direction centered on the X axis in the figure.

11 (a) and 11 (b) show adjustment in the rotation direction (indicated by an arrow in the figure) about the Y axis in the figure, in particular, by rotating the adjustment dial 3-90. That is, by rotating the adjustment dial 3-90 shown in FIG. 11 (a), the projector device (main body) 1 is moved within the moving range shown in FIG. 11 (b), that is, centered on the Y axis in the figure. It is possible to make adjustments in the direction of rotation. In particular, since the hemispherical bearing 523 is located near the emission from the projector device, the positional deviation of the projected image can be suppressed to be small when adjusting around the X-axis and the Y-axis. Further, since the change in the projection distance can be minimized at the time of adjustment, the change in the projection size can be minimized.

Further, FIGS. 12 (a) and 12 (b) show, in particular, by rotating only one of the adjustment dials 1-70 and 2-80, or both of them in opposite directions. The adjustment in the rotation direction around the Z axis (indicated by the arrow in the figure) is shown. That is, by rotating the adjustment dial 1-70 and / and the adjustment dial 2-80 shown in FIG. 12 (a), the projector device (main body) 1 is moved within the movement range shown in FIG. 12 (b). That is, it is possible to adjust the rotation direction around the Z axis in the figure. Since the adjustment dials 70 and 80 are positioned substantially evenly on the left and right in the image projection direction with respect to the hemispherical bearing 523, it is possible and necessary to adjust the X-axis and the Y-axis with the two adjustment dials. It is easy to grasp the adjustment amount. In particular, the triangle composed of the bearing 523 and the dials 70 and 80 includes the center of gravity of the projector device inside, so that an excessive load is not applied to a part of the three locations, and the adjustment work is smooth. It's easy.

FIG. 13 shows the relationship between the rotation axis that can be adjusted by the above-mentioned three adjustment dials and the tendency of image distortion that accompanies it. In the above-mentioned three-axis adjustment mechanism, the three-axis adjustment is performed by appropriately rotating the adjustment dials 1, 2, 3-70, 80, 90 also shown in FIG. 9. The amount of movement in the axial direction of the screw groove depends on the pitch of the screw groove, and in order to perform finer position adjustment, the pitch of the screw (screw) groove formed on the surface of the adjustment dial may be made finer. For example, the pitch of the M3 coarse screw is 0.5 mm, but the pitch of the fine screw is 0.35 mm, which makes it possible to reduce the amount of movement per rotation. Further, by increasing the diameter of the adjustment dial operation unit (see reference numeral 73 in FIG. 9), the amount of movement of the operation unit per rotation can be increased. Therefore, for example, when the operation unit is turned by hand. The amount of movement in the axial direction becomes smaller than the amount of movement, making it easier to make fine adjustments.

As described in detail above, according to the mounting member 50 of the present invention, the projector fixing bracket 520 fixed to the projector device (main body) 1 has three axes using a hemispherical shaft 512 and a hemispherical bearing 523. By adopting a configuration that can be adjusted in the direction, the wall fixing bracket 510 attached to the wall surface 60 can be rotated and moved to be adjusted. Therefore, when the wall fixing bracket 510 to be attached to the wall surface 70 is attached, for example, out of the original attachment position (for example, slightly inclined with respect to the vertical direction or the horizontal direction of the wall surface), or further. When the projector device (main body) 1 is tilted due to an external force such as an earthquake or human contact and the projection screen is distorted, the projection screen can be easily distorted by adjusting it again in the three-axis directions with the above adjustment dial. It becomes possible to correct it.

In the above example, the three adjustment dials have been described as being attached to a part of the wall fixing bracket 510 attached to the wall surface 60, but the present invention is not limited to this, and the number of adjustment dials is not limited to this. To two (eg, adjustment dials 1-70 or 2-80 and adjustment dial 3-90), or attach those adjustment dials to the projector fixing bracket 520 side instead of the wall fixing bracket 510. However, it is natural for those skilled in the art to be able to obtain the same effect.

Further, in the above embodiment, a hemispherical shaft / bearing is used as a means for rotatably connecting the projector fixing bracket 520 to the wall fixing bracket 510. However, the present invention describes the present invention. The present invention is not limited to this embodiment, and for example, a spherical shaft / bearing or other mechanism may be used, as long as they can rotate freely with each other.

It becomes adjustable. Therefore, when the wall fixing bracket 510 to be attached to the wall surface 70 is attached, for example, out of the original attachment position (for example, slightly inclined with respect to the vertical direction or the horizontal direction of the wall surface), or further. When the lighting device (main body) is tilted due to an external force such as an earthquake or human contact and the projection screen is distorted, the projection screen can be easily distorted by adjusting it again in the three-axis directions with the above adjustment dial. It becomes possible to correct it.

Furthermore, the present invention is not limited to the above-described examples, and includes various modifications. For example, the above-described embodiment describes the entire apparatus in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the configurations described.
