  As described above, the structure and installation work of the wall hanging device in the market have the following problems.

  Since the wall-mounted unit (wall-mounted device) is designed to require strength for safety, it often has a mass exceeding 10 kg, so it is difficult to hold it with one hand when fixing it to the wall with screws. Two or more workers are required. Also, since the TV has a screen size of 40 inches and is generally 30-40 kg, it cannot be lifted by one person, requiring two or more workers, and sliding the hand down to drop the TV. It is a work that involves failure to break.

  In the prior application Japanese Patent Application Laid-Open No. 2001-282131, installation work of a thin image display device can be easily performed by one or two people, but no method or structure for installing on a wall surface has been proposed. It is difficult to apply to means for rotating around the fixing part or fixing it to the wall surface when moving up.

  In other words, even though various installation environments can be selected due to the widespread use of liquid crystal panels and plasma display panels, if a user wants to install on a wall, he or she must ask a serviceman or a specialist. The cost burden became a problem, and there was anxiety that the equipment was damaged during the work.

  The present invention makes it possible to install a thin image display device having a mass exceeding 40 inches on the wall surface by a small number of workers or the user himself / herself relatively safely, improving the convenience of the user and reducing the economic burden. The purpose is to reduce.

  In order to solve the above-described problems, the wall hanging device of the present invention is configured by a wall hanging device movable portion that is fixed to the back surface of the thin display device and a wall hanging device fixing portion that is slidably fixed to the wall surface.

  Furthermore, both provided the positioning mechanism by the fitting part and guide rail at the time of raising along a wall surface, and the fall prevention mechanism which combined the nail | claw and the fitting part.

  In addition, in order to assist the ascending operation of the thin display device, the ascending guide having a continuous locking hole and the ascending device using the lever principle by lever operation are combined.

  In addition, by connecting an installation device having two guide rails and telescopic legs to a wall hanging device, a thin display device lying on the floor surface is lifted to the wall surface by the principle of leverage.

  Further, when the wall-hanging device fixing portion is fixed to the wall surface, the installation device supports the weight of the device.

With the above configuration,
1. The burden of positioning the thin display device with respect to the wall hanging device is reduced.
2. It also has an effect of preventing scratches on the thin display device and the wall surface during installation work.
3. The effort to lift the thin display device to a desired height is reduced.
4). It also has the effect of preventing the thin display device from falling during installation work.
5. The thin display device can be lifted from the floor surface to the wall surface with a smaller force.
6). Screwing to fix the wall hanging device to the wall surface enables one person to work.
It has the effect.

Therefore, as the nut 16-b is tightened, the taper surface is gradually reduced by applying pressure to the threaded portion 16-a of the guide rail 12, and the outer peripheral portion of the telescopic leg 17 is within the threaded portion 16-a. The two parts (the outer peripheral part of the telescopic leg 17 and the inner peripheral part of the screw part 16-a) are fastened by the peripheral part. Further, when the nut 16-b is turned in the loosening direction from the tightening direction, the inner peripheral tapered surface of the nut 16-b is gradually retracted to remove the pressure on the screw portion 16-a. When the elastic deformation of -a is restored, the previously fixed state (the outer peripheral portion of the elastic leg 17 and the inner peripheral portion of the screw portion 16-a) is released, and the elastic leg 17 can move freely.

  FIG. 5 is an enlarged view showing a state in which the fitting portion 6 of the wall hanging device movable portion 1 of the present invention is fitted to the guide rail 8 of the wall hanging device fixing portion 7 and the guide rail 12 of the installation device 11. Here, the function of the guide rail claws 8-a and 12-a will be described. In the wall surface installation state, the left direction in the figure is up. The fitting portion 6 slidably fitted to the guide rails 8 and 12 pushes and extends the slopes of the guide rail claws 8-a and 12-a when ascending, and loosens the lifting force when descending. In this case, the fitting part 6 comes into contact with and stops at the position shown in the figure, exactly at the tips of the guide rail claws 8-a and 12-a.

  In the present invention, the guide rail claw and the cylindrical fitting portion are employed as the structure related to the above-described raising operation of the fitting portion 6 and the stopping operation at the time of lowering. Other configurations may be used as long as the structure is “Yes”.

  This is the end of the description of the structure of the present invention. Next, the installation method of the thin display device 2 using the installation device 11 and the characteristics of the wall hanging device will be described.

  FIG. 6A to FIG. 6D show an installation procedure of the thin display device 2 using the installation device 11. The description will be added in order, but the component names and numbers described in FIGS. 1 to 5 are used as they are.

  In FIG. 6A, first, the back of the thin display device 2 opposite to the image display surface is placed on the floor, and the wall hanging device movable portion 1 is then placed on the thin display device 2. Thereafter, four fixing screws are inserted into the reinforcing plate screw portion and fixed. The installation device 11 is placed on the wall hanging device movable portion 1. At that time, the four fitting portions 6 of the wall hanging device movable portion 1 pass through the guide rail cutout 12-b of the installation device 11 and are inserted into the substantially U-shaped cross section of the guide rail 12. And confirm that they are mated.

  6B, first, the installation device 11 is moved in the wall direction (the fitting portion 6 slides inside the guide rail 12) so that the telescopic tip 18 is in contact with the wall surface. At this time, the length of the telescopic leg 17 may be adjusted by loosening the nut 16-b of the telescopic structure section 16.

  Next, the lower end 8-c of the guide rail of the wall-hanging device fixing portion 7 is inserted almost simultaneously to the wall-hanging device connecting portion 14 of the installation device 11. After visually confirming that the guide rails 8 and 12 of both apparatuses are connected, the connecting portion screw 15 is firmly tightened. The fastening of the installation apparatus 11 and the wall hanging apparatus fixing | fixed part 7 was completed by the above.

  In FIG. 6C, the thin display device 2 is slowly lifted by grasping the guide rail 8 near the upper end of the wall-hanging device fixing portion 7. At this time, it is raised while confirming that the telescopic tip 18 of the installation device 11 is in contact with the corner of the floor and wall shown in the figure. Due to the lever principle, it can be lifted with a force lighter than the mass of the thin display device 2. That is, the guide rail 8 near the upper end of the wall-hanging device fixing portion 7 is a force point, the telescopic tip portion 18 of the installation device 11 is a fulcrum, and the attachment portion of the thin display device 2 is an action point.

  FIG. 6-d shows a position where the wall-hanging device fixing portion 7 has come into close contact with the wall surface to be installed. Thereafter, the four wall screws fixed to the wall surface are inserted into the wall surface fixing holes 9-a of the rail coupling plate and tightened firmly, whereby the wall surface fixing of the wall hanging device fixing portion 7 is completed.

  In FIG. 6-e, it is safe even if the operator removes his / her hand from the wall-hanging device fixing portion 7 or the installation device 11. The hand is put on the bottom of the thin display device 2 and slowly lifted. At this time, the thin display device 2 is slidable on the back side so that the fitting portion 6 of the wall-hanging device movable portion 2 can slide on the guide rail 12 of the installation device 11 and the guide rail 8 of the wall-hanging device fixing portion 7 as it rises. Since it is fitted, it can be lifted without shifting or tilting left and right, and the guide rails 8 and 12 are formed with claws 8-a and 12-a at equal intervals. When the force to lift the thin display device 2 is removed, the fitting portion 6 is caught by the nearest nail 8-a or 12-a and stops. Therefore, the operator does not have to lift the thin display device 2 to a desired height at a time, and can work while taking a break.

  6F, after the thin display device 2 reaches a desired height, the female screw 6-a formed in the fitting portion 6 is looked into the opening of the long hole 8-b formed in the guide rail 8. Since it is in the position, the fitting portion 6 is fixed to the guide rail 8 by screwing the two fixing screws 10 on the left and right. That is, the thin display device 2 is fixed to the wall hanging device fixing portion 7 through the wall hanging device moving portion 1. Thereafter, the nut 16-b of the expansion / contraction structure 16 at the upper end of the installation device 11 is loosened, the expansion / contraction leg 17 is contracted, and the installation device 11 is removed from the wall hanging device fixing unit 7 to complete the operation.

  Next, the features of the wall hanging apparatus will be described. There are four major differences from the structure of the conventional wall hanging device. The first effect is due to the fitting between the fitting portion 6 and the guide rail 8, and it has a structure that does not tilt or rotate when the thin display device 2 is lifted, and maintains the guide toward a desired height. is there. In conventional wall-mounted devices, it is very difficult to lift a thin display device with a mass to a desired height, and more precisely align the hook to the locked portion of the wall-mounted device. There was also a risk of damaging the equipment and walls.

  The second is that when the thin display device 2 is lifted, the fitting portion 6 and the claw 8-a of the guide rail are caught and do not fall even if the hand is released. In the conventional wall-mounted device, a thin display device having a large mass is lifted to a desired height, and further, it is necessary to have physical strength or an operator's hand to continue lifting for a long time until the fixing is completed. In addition, since the said nail | claw of this invention has moderate elasticity with the characteristic of a material and a shape, when the said fitting part 6 raises, since the nail | claw 8-a bends, the said raising operation | movement is not prevented.

  The third point is that the thin display device 2 hung down on the floor surface can be lifted up to the wall surface with a light force based on the lever principle by the installation device 11 connected to the wall hanging device fixing portion 7. Conventionally, in order to lift the thin display device taken out from the packing material to the wall surface, it was based on human hands without using a tool for reducing the work load.

  The fourth is a structure in which the installation device 11 supports the mass of the device fixing portion 7 together with the thin display device 2 when the wall hanging device fixing portion 7 is fixed to the wall surface. The screw can be fixed to the wall while supporting it with one hand so that it does not fall down. Conventionally, an operator who supports the wall hanging device and another worker who screws the wall hanging device to the wall surface are required.

As described above, if the wall hanging device of the present invention is used when fixing the thin display device to the wall surface,
7). The burden of positioning the thin display device with respect to the wall hanging device is reduced.
8). At the same time, it has an effect of preventing scratches on the thin display device and the wall surface.
9. The effort to lift the thin display device to a desired height is reduced.
10. At the same time, it also has the effect of preventing the thin display device from falling.
11. The force for lifting the thin display device from the floor surface to the wall surface may be less than the mass of the thin display device.
12 When fixing the wall hanging device to the wall surface, it is possible to perform the screwing operation while holding it with one hand alone.

  The above effects can be obtained.

  In the present invention, the thin display device is taken as an example of the object fixed to the wall surface. However, the present invention is not limited to this. For example, the present invention can be applied to air conditioners, furniture, signboards, and other shaped objects installed on the wall surface.

(Example 2)
FIG. 7 is a plan view of the installation device that represents the feature of the second aspect of the present invention, showing a state of a horizontal posture for preparing to install a thin display device, and the left direction of the drawing is in a vertical posture along the wall surface. Above. The same parts as those in the first embodiment are shown with the same numbers added or omitted.

  Reference numeral 20 denotes an installation apparatus of the present invention. Unlike the installation apparatus 11 according to the first embodiment, the rail coupling plate 13 is increased in two places at the top and bottom, and a new guide rail 22 having a different shape from the rising guide 21 is provided. The ascending guide 21 is located at the center of the left and right sides of the thin display device 2, exactly in the center of the two guide rails 22, and the upper and lower portions are fixed to the rail coupling plate 13 by welding or screwing (not shown). A steel material is formed by pressing. Reference numeral 21-a denotes a plurality of locking holes formed in the center of the plate width of the ascending guide 21 by the same press work, which are arranged in the same shape and at almost equal intervals. Details of the guide rail 22 will be described later with reference to FIG.

  FIG. 8 is an enlarged view of the central section standing section of the installation apparatus representing the feature of the second aspect of the present invention. The bottom of the thin display device is just shown, and the guide rail 22 is omitted from the drawing. Reference numeral 23 denotes a lifting device, which is a device for lifting the thin display device 2. Reference numeral 24 denotes a lever as a main component part of the ascending device 23 formed by pressing a steel plate, and a rotatable long hole is formed near the center. Reference numeral 24-a denotes a locking portion formed at the tip of the lever 24 and has a hook shape. Reference numeral 24-b denotes a handle of the lever 24, which is a part to be grasped and operated by a person, so that the surface is smoothly finished. Reference numeral 25 denotes a receiving portion which is located near the center of the lever 24 and has a relatively rotatable structure, and an upper portion is made of aluminum and is formed by a smooth flat portion for receiving the thin display device 2. This is a cast product. Reference numeral 26 denotes a rotating shaft for relatively rotating the lever 24 and the receiving portion 25. The receiving portion 25 supports both ends of the rotating shaft, and the lever 24 is rotatably fitted near the center. Match.

  FIG. 9 is an enlarged view of a longitudinal section of the guide rail 22 of the installation device 20 representing the characteristics of the second aspect of the present invention, and shows a fitting state of the wall hanging device movable portion 1 and the installation device 20. In the vertical posture when the apparatus is installed on the wall surface, the left direction in the figure is up. Reference numeral 27 denotes a fitting portion formed at a total of four locations on both ends of the support shaft 5 of the wall-hanging device movable portion. Inside the cylindrical shape is a compression spring, a fixing member for the spring, and a guide for an elastic claw 28 described later (whichever Are also not shown). The elastic claw 28 is disposed so as to protrude in two directions from the cylindrical surface 27-a of the fitting portion 27. However, when a force against the internal compression spring is applied, the elastic claw 28 is stored in the cylindrical surface 27-a.

  The above will be described in combination with the guide rail 22. When the wall-hanging device movable portion 1 is raised (the thin display device 2 is raised), the fitting portion 27 slides inside the guide rail 22. In the portion where the hole 22-a of the guide rail does not exist, the elastic claw 28 is housed inside the cylindrical surface 27-a of the fitting portion, and in the portion passing through the hole 22-a of the guide rail, 28 is in a protruding state shown in FIG. Next, when approaching the end of passing through the hole 22-a of the guide rail, the upper end of the hole 22-a of the guide rail comes into contact with the inclined surface of the elastic claw 28, and the elastic claw 28 gradually starts moving in the storing direction. The fitting portion is stored in the cylindrical surface 27-a.

  If the operator relaxes the lifting force of the apparatus and starts to descend, the elastic claw 28 is housed inside the cylindrical surface 27-a of the fitting portion in the portion where the hole 22-a of the guide rail does not exist. In this state, the elastic claw 28 is in a protruding state shown in FIG. 9 at a portion passing through the hole 22-a of the guide rail. However, the lowering state stops when the lower portion of the elastic claw 28 (opposite side of the slope 28-a) and the right end of the drawing contact the lower end of the hole 22-a of the guide rail. That is, the elastic claw 28 is caught in the hole 22-a of the guide rail, and the lowering of the thin display device can be stopped.

Next, the operation of the lifting device 23 will be described with reference to FIG. For the thin display device 2 that is stopped at an arbitrary position of the installation device 20 in the vertical posture, first, the locking portion 24-a of the lifting device 23 is inserted into the locking hole 21-a of the lifting guide 21 to the illustrated position. It will be in the state hooked by. Next, the lever 24 is slowly lifted in the upward direction by holding the handle 24-b, and the center of rotation at this time is the locking portion 24-a. The upper flat portion of the receiving portion 25 is brought into contact with the bottom portion of the thin display device 2 with the other hand. From here, the thin display device 2 starts to be massed. When the handle 24-b is lifted, the thin display device 2 starts to rise in conjunction with it. At this time, the mass applied to the handle 24-b is about half of the total sum of the thin display device 2 and the wall hanging device movable portion 1, and the burden is reduced as it is lifted alone by a 40-inch class television. After raising the locking holes 21-a by two to three and then releasing the force applied to the handle 24-b, the thin display device 2 stops rising and gradually begins to descend. However, as described above, the elastic claw 28 is caught in the hole 22-a of the guide rail and stops the lowering of the thin display device.

  Thereafter, the lifting device 23 is removed from the lifting guide 21 (the locking portion 24-a is removed from the locking hole 21-a and the contact of the receiving portion 25 is released from the thin display device 2), and the next lifting is performed. In order to prepare for the operation, the latching portion 24-a of the lever 24 is replaced with the latching hole 21-a of the ascending guide 21 positioned two or three more. By continuing the operation of the raising device 23 described above, the thin display device 2 can be raised to a desired height. Although not shown in the drawing, as in the first embodiment, the installation device 20 is possible because the wall-hanging device fixing portion 7, the guide rail 22, and the ascending guide 21 are continuous.

To summarize the features of the wall hanging device described above,
The fitting portion 27 and the guide rail 22 of the installation device 20 are configured as a positioning structure when the wall hanging device movable portion 1 is raised (the thin display device 2 is raised). Further, the wall-hanging device movable portion 1 slides so as to be able to rise, but a structure that restricts the descent is realized by the following combination.
