[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and redundant explanations will be omitted.

[0009] Fig. 1 is an overall view of a display stand 100 as a display support device of this embodiment, Fig. 1(a) is a front view, and Fig. 1(b) is a side view. As shown in Figure 1, the display stand 100 comprises a base member 30 and support columns 20 serving as support members extending upward from the left and right ends of the base member. Canisters 31 are attached to the four corners of the underside of the base member. The display stand 100 also has a mounting plate 10 serving as a mounting member to which the display 1 is attached, and the mounting plate 10 is attached to a pair of support columns 20.

[0010] Examples of the display 1 include analog boards such as whiteboards, blackboards, and canvases, as well as input-capable display devices such as interactive whiteboards, interactive flat panel displays, and electronic panels such as touch panels. The display 1 may also be a passive display device such as a monitor or television.

[0011] FIG. 2 is a perspective view showing a portion of the mounting plate 10 and the support column 20, and FIG. 3 is a top view and a front view showing the mounting plate 10 and the support column. The mounting plate 10 is made of sheet metal and has mounting portions 11 extending rearward from both left and right ends. These mounting portions 11 are attached to side surfaces 21 of the support columns 20. By attaching the mounting portions 11 to the pair of support columns 20, the mounting plate 10 is supported in a manner that it is suspended from the pair of support columns.

[0012] 4(a) is a diagram showing the mounting portion 11 of the mounting plate 10, and FIG. 4(b) is a diagram showing the side portion 21 of the support column 20. As shown in FIG. As shown in FIG. 4(a), the mounting plate 10 has a hook portion 12 at the top of the mounting portion 11, and a screw through hole 13 as a fixing portion through which a screw serving as a fastening member passes at the bottom.

[0013] 4(b), three hooking screw holes 22a, 22b, and 22c are formed at predetermined intervals in the vertical direction on side surface 21 of support 20. These hooking screw holes 22a, 22b, and 22c serve as hooking portions for hooking hook portion 12 and as fastening portions for fastening screws serving as fastening members. Three fixing screw holes 23a, 23b, and 23c are also formed at predetermined intervals in the vertical direction on side surface 21 and as fastening portions for fastening screws for fastening the lower part of mounting plate 10. A rotation prevention pin 24, which functions as a rotation prevention portion and a protrusion and is provided so as to protrude from side surface 21, is provided between bottom hooking screw hole 22c and top fixing screw hole 23a.

[0014] Next, changing the height of the display 1 will be described. FIG. 5 is a diagram illustrating how the height of the display 1 is changed. 5(a), the hook portion 12 of the mounting portion 11 of the mounting plate 10 is fastened to the side surface portion 21 in a state where it is hooked onto the body of a screw 56 screwed into the hooking screw hole 22b. In addition, the lower portion of the mounting plate 10 is fastened to the side surface portion 21 by a screw 57 screwed into the fixing screw hole 23b. In this way, the upper and lower parts of the mounting portion 11 of the mounting plate 10 are fastened to the side portion 21 of the support column 20 with screws, so that the display 1 can be attached to the display stand 100 without rattle. Furthermore, the display 1 will not come off the display stand 100, which prevents the display 1 from falling off the display stand 100 and reduces damage to the display 1.

[0015] When changing the height of the display 1, as shown in Fig. 5(b), the screw 57 used as the fastening member for fixing is removed from the fixing screw hole 23b, and the screw 57 is screwed into the hooking screw hole corresponding to the changed height. In the example of Fig. 5, the screw 57 is screwed into the uppermost hooking screw hole 22a. At this time, the screw 57 is screwed into the hooking screw hole 22a so that there is a predetermined gap between the head of the screw 57 and the side surface portion 21 so that the hook portion 12 can be hooked onto the body of the screw 57.

[0016] Next, the screw 56 used as a fastening member for hanging is loosened. When the screw 56 is loosened, the weight of the display 1 attached to the mounting plate 10 causes the mounting plate 10 to rotate together with the display 1 in the direction of the arrow in FIG. 5(b) (counterclockwise in the figure) with the screw 56 as the fulcrum. At this time, the anti-rotation pin 24 abuts against the mounting portion 11, restricting the rotation of the mounting plate 10 together with the display 1 in the direction of the arrow in FIG. 5(b) (counterclockwise in the figure). This eliminates the need for the worker to support the display 1 while loosening the screw 56 to prevent it from rotating. This makes it easy to change the height of the display.

[0017] After loosening the screw 56, the worker lifts up the display 1 as shown in Fig. 5(c), and then hooks the hook portion 12 onto the body of the screw 57 as shown in Fig. 5(d).

[0018] Next, the worker removes the screw 56 from the hooking screw hole 22b. If the worker releases the display 1 while removing the screw 56 from the hooking screw hole 22b, the weight of the display 1 will cause the mounting plate 10 to rotate together with the display 1 in the direction of the arrow in FIG. 5(d) (counterclockwise in the figure), with the screw 57 as the fulcrum. At this time, the anti-rotation pin 24 also hits the mounting portion 11, restricting the mounting plate 10 from rotating together with the display 1 in the direction of the arrow in FIG. 5(b) (counterclockwise in the figure). This means that the worker does not need to support the display 1 to prevent it from rotating when removing the screw 56. This makes it easy to change the height of the display.

[0019] After removing the screw 56 from the hooking screw hole 22b, the screw 56 is screwed into the uppermost fixing screw hole 23a to be used as a fastening member for fixing. At this time, rotation is restricted by the anti-rotation pin 24, and the mounting plate 10 is in a posture substantially similar to that when fixed, and as shown in FIG. 5(d), the uppermost fixing screw hole 23a into which the screw 56 is screwed is positioned within the screw through hole 13. Therefore, the screw 56 can be passed through the screw through hole 13 and screwed into the uppermost fixing screw hole 23a without adjusting the position of the mounting plate 10.

[0020] Screw 56 is screwed into fixing screw hole 23a at the top to fasten the lower part of mounting part 11 to side part 21, and then screw 57 is tightened to fasten the upper part of mounting part 11 to side part 21. As a result, the height of display 1 is changed to a one-step higher position, and display 1 is attached to display stand 100.

[0021] In this embodiment, even when the screw fastening the lower part of the mounting part 11 is removed and the restriction on rotation by the screw is released, the display 1 can be supported on the support column in a posture substantially equivalent to that when fixed (in use) by the hook part 12 and the anti-rotation pin 24. This eliminates the need for an operator to support the display 1 while attaching / detaching the display 1 to / from the display stand 100 to change the display height. This makes it easy to change the display height. Furthermore, although the display height change operation has been described above, the display 1 can also be easily attached / detached to / from the display stand 100.

[0022] In this embodiment, the part for hooking the hook portion 12 and the part for fixing the lower part of the mounting portion 11 are made of a common screw, and are interchangeable. For example, if the screw for hooking the hook portion 12 and the screw for fixing the lower part of the mounting portion 11 are not common and the screw for fixing the lower part of the mounting portion 11 cannot be screwed into the hooking screw holes 22a to 22c, the height can be changed by the following procedure. That is, after removing the screw for fixing the lower part of the mounting portion 11, the display is temporarily lowered and the screw for hooking the hook portion 12 is replaced with the screw for hooking the hook portion 12 into the hooking screw hole 22a that corresponds to the changed height. The display is then lifted up and the hook portion is hooked onto the shaft of the screw. In this way, if the screw for hooking the hook portion 12 and the screw for fixing the lower part of the mounting portion 11 are not common, it is necessary to temporarily lower the display 1.

[0023] In contrast, in this embodiment, the part for hooking the hook portion 12 and the part for fixing the lower part of the mounting portion 11 are made to be the same screw, and are interchangeable. This allows the height to be changed without having to take the display 1 down, as explained with reference to Fig. 5, and improves the workability of changing the height. Furthermore, the height of the display 1 can be changed using two screws, which reduces the number of parts and prevents the cost of the device from increasing.

[0024] The configuration described in Patent Document 1, in which hook portions are provided at the top and bottom of the mounting portion 11, also allows for height adjustment without first lowering the display. However, in Patent Document 1, the hook portions at the top and bottom are simply hooked onto horizontal members attached to the support. This raises the risk of the display 1 rattling or coming off the display stand 100. Furthermore, to adjust the height in one step, at least three horizontal members are required, and to adjust the height in two steps, at least four horizontal members are required. This increases the number of components, potentially increasing the cost of the device. Furthermore, in Patent Document 1, the upper and lower hook portions must be hooked onto the horizontal members simultaneously. This requires the display to be lowered slowly while checking the relative positions of the upper and lower hook portions and the horizontal members, making installation and height adjustment difficult.

[0025] In contrast, in this embodiment, the upper and lower parts of the mounting part 11 are fastened to the side part 21 of the support by screws 56 and 57, so the display 1 does not rattle or come off the display stand 100. Also, the height can be changed in multiple stages using only the two common screws 56 and 57, which reduces the number of parts and the cost of the device compared to the configuration described in Patent Document 1. Also, during the installation work, only the upper hook part needs to be hooked onto the hook part on the side part 21, so the hook part can be easily hooked and the installation work can be done easily.

[0026] Next, a modification of this embodiment will be described. FIG. 6 is a diagram illustrating the process of changing the display height in a modified example of this embodiment. In this modification, an elongated hole 14 extending in the vertical direction is provided in the mounting portion 11 of the mounting plate 10, and into which a locking pin 24 is inserted. The rest of the configuration is the same as that of the embodiment. 6(b), in this modified example, even when the screw 57 fastening the lower part of the mounting part 11 is removed and the restriction on rotation by the screw 57 is released, the anti-rotation pin 24 abuts against the side surface of the elongated hole 14 on the display side, restricting rotation due to the display's own weight. As a result, when the screw 57 is removed, the worker does not need to support the display 1 to prevent it from rotating due to its own weight, and the height adjustment work can be performed easily.

[0027] In this modification, as shown in Fig. 6(c), with the mounting plate 10 (display 1) restricted in its position in the front-to-rear direction by the anti-rotation pin 24 and the elongated hole 14, the hook portion 12 is re-hooked onto the screw 57 fastened to the hooking screw hole corresponding to the changed height (the uppermost hooking screw hole 22a in Fig. 6). This prevents the display from shifting significantly forward or backward, and makes it easy to re-hook the hook portion 12.

[0028] Furthermore, although the above description has been given of an example in which the present invention is applied to a display stand in which the mounting plate 10 is attached to a pair of support columns 20, the present invention can also be applied to a display stand in which the mounting plate 10 is attached to a single support column 20, as shown in FIG. 7. As shown in the top view, the display stand shown in FIG. 7 has a predetermined gap between the mounting plate 10 and the support column 20 in the front-to-rear direction. Therefore, when the screw 57 fastening the lower part of the mounting portion 11 is removed and the restriction on rotation by the screw 57 is released, the display will rotate due to its own weight, with the hook portion hooked on the screw as a fulcrum. Therefore, the display support device shown in FIG. 7 also has a rotation prevention pin 24 to restrict the rotation of the display when the screw fastening the lower part of the mounting portion 11 is removed, thereby facilitating height adjustment and installation / removal operations, as described above.

[0029] In this embodiment, an example has been described in which the present invention is applied to a display stand as a display support device, but the present invention can also be applied to a suspension device for suspending a display on a wall surface of a room, etc., as a display support device.

[0030] The above description is merely an example, and each of the following aspects provides unique effects. (Aspect 1) In a display support device such as a display stand 100 that has an attachment member such as a mounting plate 10 to which a display 1 is attached, and a support member such as a support post 20 that supports the attachment member, the attachment member has a hook portion 12 that is hooked onto a hook portion such as a screw 56 provided on the support member, and a fixing portion such as a screw through hole 13 that is provided below the hook portion 12 and fixed to the support member by a fixing fastening member such as a screw 57, and has a rotation prevention portion such as a rotation prevention pin 24 that prevents the display from rotating due to its own weight with the hook portion as a fulcrum when the fixing fastening member is removed. In Patent Document 1, when attaching the mounting base serving as a mounting member to which the display is attached to a support pole serving as a support member, it is necessary to simultaneously hook the upper and lower hook portions onto the horizontal member serving as the hooking portion. Therefore, while checking the positions of the upper and lower hook portions, the mounting base to which the display is attached must be slowly lowered and the upper and lower hook portions must be hooked onto the horizontal member, which is not an easy task to attach the mounting member to the support member. On the other hand, in the first aspect, the attachment member is attached to the lower support member by fastening with a fixing fastener. This allows only the upper hook portion to be hooked onto the hook portion, which makes the hooking operation easier than with a configuration having multiple hook portions in the vertical direction. Furthermore, by providing the anti-rotation portion, even if the user releases the mounting member after hooking the hook portion onto the catch portion, the mounting member will not rotate around the hook portion as a fulcrum due to the weight of the display, and the fixing portion can be positioned approximately at the fixing position on the support member. As a result, when fixing the fixing portion to the support member with the fixing fastening member, there is no need for the worker to support the display or the mounting member to which the display is attached so that the fixing portion is positioned at the fixing position on the support member, and the fixing portion can be easily fixed to the support member with the fixing fastening member.

[0031] (Aspect 2) In aspect 1, the hook portion is a hooking fastening member such as a screw 56 that is fastened to the support member, and the support member is provided with a plurality of fastening points in the vertical direction, such as fixing screw holes 23a to 23c into which fixing fastening members such as a screw 57 are fastened, and a plurality of fastening points such as hooking screw holes 22a to 22c into which hooking fastening members are fastened. This allows changing the fastening points of the hooking fastening members and the fastening points of the fixing fastening members to change the height of the display 1. Also, it is possible to change the height of the display 1 using two fastening members, which reduces the number of parts and cuts down on the cost of the device.

[0032] (Aspect 3) In the second aspect, the fixing fastening member and the hooking fastening member are formed from a common part. According to this, the fixing fastening members can be removed and used as hanging fastening members by fastening them to fastening locations such as the hooking screw holes 22a to 22c to which the hanging fastening members are fastened, and the hooking fastening members can be used as fixing fastening members by fastening them to fastening locations such as the fixing screw holes 23a to 23c. This allows the height of the display to be changed without having to first lower the display, as described in the embodiment.

[0033] (Aspect 4) In any of the first to third aspects, the anti-rotation portion is provided on a support member such as the support column 20, and has a protrusion such as an anti-rotation pin 24 against which the mounting member abuts. With this, when the fastening member for fixing is removed, if the display tries to rotate due to its own weight with the hook portion as a fulcrum, the mounting member will hit the protrusion, and the rotation will be restricted.

[0034] (Aspect 5) In the fourth aspect, the attachment member has a vertically long slot through which the protrusion passes. As a result, as explained in the modified example, when changing the height, the protrusion and the long hole can regulate the front-to-rear position of the display relative to the support member, making it easier to change the height.
