Description

  The present invention relates to an installation device and an installation method for installing an image display device on a wall surface.

  With the reduction in thickness and weight of image display devices, methods and devices for installing image display devices on wall surfaces have been put into practical use. Although methods and devices that are installed on the installation surface of a TV stand, etc., have been put into practical use, not on the wall surface, the attention to the installation on the wall surface is increasing from the viewpoint of earthquake resistance, design, freedom of installation, etc. .

  When installing the image display device on a wall surface, an installation device having a first fixing member fixed to the rear surface of the image display device that displays an image on the front surface and a second fixing member fixed to the wall surface is used. The worker who performs installation fits the fitting portion in the first fixing member into the fitting portion in the second fixing member, and installs the image display device on the wall surface. An operator who holds the image display device for fitting is difficult to see the rear side of the image display device. Therefore, it is not easy for the operator to install the image display device held on the wall by adjusting the vertical and horizontal directions.

  In Non-Patent Document 1, the four corner expected positions of the image display device after being installed on the wall surface are recorded in advance on the wall surface, and the image display device is adjusted so that the position of the image display device held in hand matches the four corner expected positions described. The method of installing the fitting part and the fitted part on the wall surface is proposed.

“Dimension drawing / Dimensions when wall mounting bracket is attached”, “When installing on a wall”, “How to install on a wall (example)” [online], [Search September 21, 2011] (http: / /www.sharp.co.jp/support/aquos/doc/size_lc80_70gl7.pdf)

  However, there is room for improvement in the conventional attempt to facilitate installation of the image display device on the wall surface. For example, it is necessary for the operator himself to write the expected four corner positions of the image display device on the wall surface in advance. If the expected four corner positions are inaccurate, it may be difficult to fit the fitting portion and the fitted portion. In addition, as the image display device held in the hand approaches the wall surface, it becomes difficult for the light to reach near the four corner expected positions on the wall surface, and the four corners of the image display device held in the hand and the four corner expected positions on the wall surface are matched. There is also a possibility that it is difficult to fit the fitting portion and the fitted portion.

  The present invention has been made in view of such circumstances, and an object thereof is to provide an installation device and an installation method that facilitate installation of an image display device on a wall surface.

  An installation apparatus according to the present invention includes a first fixing member that is fixed to a rear surface of an image display device that displays an image on a front surface, and a second fixing member that is fixed to a wall surface. In an installation apparatus in which a certain fitting portion is fitted to a fitted portion on the image display device side of the second fixing member and the image display device is installed on the wall surface, provided on the wall surface side of the first fixing member. A light emitting portion for emitting beam light on the image display device side of the second fixing member, and provided on the image display device side of the second fixing member, and the reflectance is different from that of the second fixing member, A reflecting member that reflects the beam light emitted from the light emitting portion, and a distance between the centers of the light emitting portion and the fitting portion is a distance between the centers of the reflecting member and the fitting portion. It is characterized by being substantially the same.

  In the above-described installation apparatus, the positional relationship between the light emitting portion that emits the beam light and the fitting portion that fits into the fitted portion is substantially the same as the positional relationship between the reflecting member and the fitted portion.

  The light beam has straightness. When the beam light is reflected by the reflecting member, the visibility of the reflected beam light is different from that when the second fixing member having no reflecting member is reflected by the image display device side. For example, when the reflectance of the reflecting member is extremely low, it becomes difficult to visually recognize the beam light reflected by the reflecting member. That is, in this example, when it is difficult to visually recognize the reflected light beam, it can be determined that the light emitting portion and the reflecting member are in a positional relationship that is connected on a straight line. In addition, when the reflection angle of the reflecting member is unusual, the trajectory of the beam light reflected by the reflecting member changes. In other words, in this example, when the trajectory of the reflected light beam becomes unusual, it can be determined that the light emitting portion and the reflecting member are in a positional relationship that is connected on a straight line. In the above-described installation apparatus, the positional relationship between the light emitting portion and the fitting portion is substantially the same as the positional relationship between the reflecting member and the fitted portion, and thus the reflected light of the beam light emitted from the light emitting portion is By considering the visual recognition mode, the positional relationship among the image display device, the first fixing member, the second fixing member, and the wall surface can be easily grasped.

  The installation apparatus according to the present invention is characterized in that the reflection member is a specular reflection member or a light absorption member.

  In the installation apparatus described above, a specular reflection member or a light absorption member is used as the reflection member. Like the mirror, the specular reflection member is a member that reflects light incident on its surface to the opposite side at the same angle, and the light absorption member is a member that absorbs incident light. By taking into consideration the visual aspect of the reflected light of the beam light emitted from the light emitting portion, the positional relationship among the image display device, the first fixing member, the second fixing member, and the wall surface can be easily grasped.

  The installation apparatus according to the present invention is characterized in that an irregular reflection member is provided around the reflection member.

  In the above installation apparatus, the irregular reflection member is provided around the reflection member. The irregular reflection member is a member that diffuses and reflects light. By using the reflected light of the beam light emitted from the light emitting part as a mark, it can be understood that the light emitting part and the reflecting member are connected in a straight line by a slight correction.

  Further, in the installation device according to the present invention, the fitted portion has a frame shape, and has a notch portion on an outer surface, and the distance between the notch portion and the center of the fitted portion is the light emitting portion and the The distance between the centers of the fitting portions is substantially the same.

  In the above-described installation device, the center distance from the fitted part includes a notch part that is substantially the same as the distance between the center of the light emitting part and the fitting part. By visually recognizing the positional relationship between the trajectory of the beam light having a straight advance and the notch, the positional relationship among the image display device, the first fixing member, the second fixing member, and the wall surface can be easily grasped.

  An installation method according to the present invention uses an installation device having a first fixing member fixed to the rear surface of an image display device that displays an image on the front surface and a second fixing member fixed to a wall surface, and the wall surface of the first fixing member In the installation method in which the fitting portion on the side is fitted to the fitted portion on the image display device side of the second fixing member and the image display device is installed on the wall surface, the first fixing member is the image. Fixing to the rear surface of the display device, fixing the second fixing member to the wall surface, preparing a light emitting portion for emitting beam light on the wall surface side of the first fixing member, and the light A step of emitting beam light from the emitting portion to the image display device side of the second fixing member, and a step of preparing a reflecting member having a reflectance different from that of the second fixing member on the image display device side of the second fixing member And the light emitting part and Adjusting the position of the second fixing member so that the distance between the centers of the fitting portions is substantially the same as the distance between the centers of the reflecting member and the fitted portion; Fitting the fitting portion of the fixing member to the fitting portion of the second fixing member that is reflected by the reflecting member that has adjusted the emitted light beam.

  In the above-described installation method, the positional relationship between the light emitting portion that emits the beam light and the fitting portion that fits into the fitted portion is substantially the same as the positional relationship between the reflecting member and the fitted portion. By considering the visual aspect of the reflected light of the beam light emitted from the light emitting portion, the positional relationship among the image display device, the first fixing member, the second fixing member, and the wall surface is grasped, and the fitting portion is fitted. Fits into the joint.

  In the present invention, the positional relationship between the light emitting portion that emits the beam light and the fitting portion that fits into the fitted portion is substantially the same as the positional relationship between the reflecting member and the fitted portion. By taking into account the visual aspect of the straight beam light and its reflected light, the positional relationship among the image display device, the first fixing member, the second fixing member, and the wall surface can be grasped. Therefore, the operation of installing the image display device on the wall surface is facilitated by the fitting of the fitting portion and the fitted portion.

(Embodiment 1)
Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.

  FIG. 1 is a schematic explanatory view for explaining the appearance of the installation apparatus 2. FIG. 2 is an explanatory diagram for explaining a method of installing the image display device 1 on a wall surface using the installation device 2. The image display device 1 includes a liquid crystal panel, an EL (electroluminescence) panel, and the like, and is a device that displays an image. The image display device 1 is installed on a wall surface via the installation device 2.

  The installation device 2 includes a first fixing member 21 that is fixed to the rear surface of the image display device 1 that displays an image on a rectangular front surface that is longer in the horizontal direction than the vertical direction, and a second fixing member 22 that is fixed to the wall surface. In the installation apparatus 2, the following description will be given with the image display apparatus 1 side as the front side and the wall surface side as the rear side. Moreover, the following description is given as a configuration in which the front side of the first fixing member 21 is fixed to the rear surface of the image display device 1 and the rear side of the second fixing member 22 is fixed to the wall surface. Further, the following description will be given as a configuration in which the image display device 1 is fixed to the wall surface by fitting the rear side of the first fixing member 21 and the front side of the second fixing member 22.

  The first fixing member 21 is composed of two columnar fittings arranged in the left-right direction on the rear surface of the image display device 1. Two protrusion-like fitting portions 211 are provided on each side surface of each columnar bracket so as to be spaced apart in the vertical direction. A light emission hole 212 for emitting beam light is provided on the front surface of each columnar bracket fixed to the image display device 1. When beam light is emitted from the rear surface side of the image display device 1, the beam light can be emitted to the second fixing member 22 through the light emission hole 212.

  The second fixing member 22 is formed into a frame shape by combining two groove-shaped angle-shaped vertical metal fittings and two plate-like horizontal metal fittings. On each side surface of each vertical bracket, two fitted portions 221 cut into a hook shape composed of a front-rear direction and an up-down direction are provided separately in the up-down direction. Each fitted portion 221 includes a front-rear direction portion 222 extending in the front-rear direction of the hook shape and a vertical direction portion 223 extending in the vertical direction of the hook shape. By fitting each fitting portion 211 of the first fixing member 21 to a hook-shaped front-rear direction portion 222 in the corresponding fitted portion 221 of the second fixing member 22, the first fixing member 21 is fixed to the second fixing member 21. The member 22 is fitted. After the fitting, the first fixing member 21 is further fitted and pushed downward, so that each fitting portion 211 comes into contact with the lower end of the vertical portion 223 in the fitted portion 221. Therefore, the first fixing member 21 can be prevented from separating from the second fixing member 22.

  The second fixing member 22 has a mirror reflection sheet 23 on the front side of each vertical bracket. Like the mirror, the mirror reflection sheet 23 is a sheet that reflects light incident on its surface to the opposite side at the same angle. The distance between the center of the mirror reflection sheet 23 and the center of the front-rear direction portion 222 of the fitted portion 221 located above is substantially equal to the distance between the center of the light emission hole 212 and the upper fitting portion 211. Further, the distance between the centers of the mirror reflection sheet 23 and the front-rear direction portion 222 of the fitted portion 221 below is substantially equal to the distance between the centers of the light emission holes 212 and the lower fitting portion 211. That is, the mirror reflection sheet 23 is disposed at a position facing the light emission hole 212 when the fitting portion 211 is fitted to the fitted portion 221.

  A cutout portion 224 cut out in the front-rear direction is provided on each side surface of each vertical bracket in the second fixing member 22. The cutout portion 224 is perpendicular to the surface of the second fixing member 22 and is arranged so as to be collinear with the mirror reflection sheet 23 in a side view. Therefore, the notch portion 224 is disposed at a position that is collinear with the light emitting hole 212 and the mirror reflection sheet 23 when the fitting portion 211 is fitted to the fitting portion 221.

  FIG. 3 is an explanatory diagram for explaining a method of emitting beam light through the light emission hole 212. Hereinafter, an example in which laser light, which is a bundle of light with the same wavelength and phase, is used as the beam light. FIG. 3A shows an image display device 1 including a laser light generator 3 that generates laser light. The laser light generated by the laser light generator 3 is forwarded to the front side of the second fixing member 22 through a light emission hole 212. An example of release is shown. FIG. 3B shows an inserted laser beam using an image display device 1 that includes an insertion port of a laser beam generator 3 that generates a laser beam and a reflecting mirror 4 that reflects the laser beam generated by the inserted laser beam generator 3. The laser light generated by the generator 3 is reflected in the direction of the light emission hole 212 by the reflecting mirror 4 built in the image display device 1, and the reflected laser light is forwarded to the front side of the second fixing member 22 through the light emission hole 212. An example of release is shown. FIG. 3C shows an externally attached laser beam generation using an image display device 1 that can be externally attached to a laser light generator 3 that generates laser light and a reflecting mirror 4 that reflects the laser light generated by the laser light generator 3. An example in which the laser beam generated by the machine 3 is reflected in the direction of the light emission hole 212 by the reflecting mirror 4 attached to the outside, and the reflected laser beam is emitted to the front side of the second fixing member 22 through the light emission hole 212 is shown. It is. With these configurations, laser light can be emitted from the light emission hole 212. Although FIG. 3 shows an example in which the laser light generator 3 is attached to the image display device 1, the laser light generator 3 may be attached to the installation device 2 itself. For example, a configuration in which the small laser light generator 3 is attached to the light emission hole 212 by preparation at the shipping stage may be adopted.

  FIG. 4 is a flowchart showing a procedure for installing the image display device 1 on the wall surface using the installation device 2. The operator fixes the front side of the first fixing member 21 to the rear surface of the image display device 1 that displays an image on the front surface (S11), and fixes the rear side of the second fixing member 22 to a desired installation position on the wall surface ( S12). The operator emits the laser beam generated by the laser beam generator 3 from the light emission hole 212 (S13), and holds it in his / her hand so that the emitted laser beam is collinear with the cutout portion 224 in a side view. The angle of the image display apparatus 1 is adjusted (S14). Even in a situation where the light is difficult to reach when the image display device 1 approaches the wall surface, the operator grasps the relationship between the image display device 1 and a desired installation position on the wall surface by the light of the emitted laser light itself. It becomes easy. In addition, when the emitted laser light is applied to the mirror reflection sheet 23, the fitting portion 211 of the first fixing member 21 is made to move to the second fixing member 22 by visually recognizing the trajectory of the mirror-reflected reflected light. It becomes easy for the operator to grasp whether or not the positional relationship that can be fitted to the fitted portion 221 is approached.

  FIG. 5 is another explanatory diagram for explaining a method of installing the image display device 1 on a wall surface using the installation device 2. When the fitting portion 211 of the first fixing member 21 is close to the positional relationship in which the fitting portion 211 of the second fixing member 22 can be fitted, but the angle of the image display device 1 held by the hand is not appropriate, The laser light emitted from the emission hole 212 and the laser light reflected by the mirror reflection sheet 23 are not on the same straight line (FIG. 5A). On the other hand, when the fitting portion 211 of the first fixing member 21 is close to the positional relationship where the fitting portion 211 of the second fixing member 22 can be fitted, and the angle of the image display device 1 held in the hand is also appropriate. In FIG. 5B, the laser light emitted from the light emission hole 212 and the laser light reflected by the mirror reflection sheet 23 are on the same straight line (FIG. 5B). Therefore, it is easy to adjust the angle of the image display device 1 held in the hand by visually recognizing the laser beam.

  The operator further adjusts the angle of the image display device 1 held in the hand with reference to the reflection state of the laser beam (S14), and the fitting portion 211 of the first fixing member 21 is moved to the second fixing member 22. It fits into the fitted part 221 (S15). The operator further fits the first fixing member 21 and pushes it down, brings the fitting portion 211 into contact with the lower end of the vertical portion 223 in the fitted portion 221 and ends the procedure.

  By the above-described procedure, it becomes easy to adjust the positional relationship between the first fixing member 21 fixed to the image display device 1 and the second fixing member 22 fixed to the wall surface, and the image display device 1 can be easily installed on the wall surface. .

(Embodiment 2)
The installation device 2 according to Embodiment 1 includes a mirror reflection sheet 23 on the front side of the second fixing member 22. The installation device 2 according to the second embodiment further includes an irregular reflection sheet 24 around the mirror reflection sheet 23 provided on the front side of the second fixing member 22. Since the other configuration is the same as that of the installation device 2 of Embodiment 1 except that the irregular reflection sheet 24 is further provided, a detailed description of the other configuration is omitted.

  FIG. 6 is a schematic diagram illustrating the irregular reflection sheet 24 provided on the second fixing member 22. 6A illustrates the front side of each vertical bracket on the second fixing member 22, and FIG. 6B illustrates the side surface side of each vertical bracket on the second fixing member 22. The second fixing member 22 whose rear side is fixed to the wall surface has an irregular reflection sheet 24 around a mirror reflection sheet 23 provided on the front side of each vertical bracket. The irregular reflection sheet 24 has a rough surface and is a sheet that reflects and diffuses incident light in multiple directions. When the laser light emitted from the light emission hole 212 is incident on the irregular reflection sheet 24, more diffused reflected light is generated as compared with the other front portion of the second fixing member 22.

  When the reflected light of the laser light emitted from the light emitting hole 212 is further diffused, it indicates that the irregularly reflecting sheet 24 is irradiated with the laser light emitted from the light emitting hole 212. Since the mirror reflection sheet 23 is arranged in the center of the irregular reflection sheet 24, when the reflected light is more diffused, the position and angle of the image display device 1 held in the hand are slightly modified. Thus, the user can grasp that the fitting portion 211 can be fitted into the fitted portion 221. That is, the positional relationship between the first fixing member 21 fixed to the image display device 1 and the second fixing member 22 fixed to the wall surface is further adjusted by adjusting the position and angle of the image display device 1 using irregular reflection as a mark. This facilitates the installation of the image display device 1 on the wall surface.

(Embodiment 3)
The installation device 2 according to Embodiment 1 includes a mirror reflection sheet 23 on the front side of the second fixing member 22. The installation device 2 according to the third embodiment is provided with a light absorbing sheet 25 (not shown) on the front side of the second fixing member 22 instead of the mirror reflecting sheet 23. Since the other configuration is the same as that of the installation device 2 of the first embodiment except that the light absorbing sheet 25 is provided instead of the mirror reflection sheet 23, detailed description of the other configuration is omitted.

  The light absorbing sheet 25 is a sheet whose surface is composed of a continuous fine porous layer and has high absorption efficiency for incident light. When the laser light emitted from the light emission hole 212 is incident on the light absorbing sheet 25, the generation of reflected light is further suppressed as compared with the other front portion of the second fixing member 22. The operator finds a position where the laser beam emitted from the light emission hole 212 is less likely to be reflected, whereby the position of the first fixing member 21 fixed to the image display device 1 and the second fixing member 22 fixed to the wall surface. It becomes easy to adjust the relationship, and the image display device 1 can be easily installed on the wall surface.

  In the above-described embodiment, two light emitting holes 212 for emitting laser light are provided in the first fixing member 21. However, one or three or more laser lights are used. Three or more light emission holes 212 may be provided.

  In the above-described embodiment, the specular reflection sheet or the light absorption sheet is used, but another member having a reflectance different from that of the front side of the second fixing member 22 may be used. It is good also as a structure which performs a coating and process in which a reflectance differs from the whole front side of the 2nd fixing member 22 partially.

  The embodiments disclosed herein are illustrative in all respects and should not be considered as restrictive. The technical features described in each embodiment can be combined with each other. The scope of the present invention is shown not only by the contents exemplified above but also by the scope of claims for patent, and it is intended to include all the updates within the meaning and scope equivalent to the scope of claims for patent.
