For example, the screw 19 is inserted into the mounting hole 49a via the mounting hole 47a. Screw in and tighten. Thereby, the display 11 can be attached to the wall surface 12 via the display support mechanism 1 according to the present invention so as to be movable in the tilt direction.

  In this way, the display 11 can be attached to the wall surface 12 by engaging the engagement hole 46a of the attachment plate 4 with the engagement convex piece 48 of the second tilting bracket 33 and then screwing it. Can be easily attached to the wall 12. That is, when the engagement hole 46a of the attachment plate 4 is engaged with the engagement convex piece 48 of the second tilting bracket 33, the display 11 is suspended and supported via the attachment plate 4, and thus the attachment hole 47a and the attachment hole 47a are attached. Since the hole alignment with the hole 49a and the screwing operation can be easily performed, the display 11 can be easily attached to the wall surface 12. Further, the engagement between the attachment portion 47 of the attachment plate 4 and the attachment portion 49 of the second tilt bracket 33 is engaged with the engagement between the first engagement portion and the second engagement portion instead of using screws, or by a lock mechanism. If this is performed, the attachment plate 4 and the second tilt bracket 33 can be attached and detached more easily.

  When the angle of the tilt direction of the display 11 is to be changed, a force is applied to the display 11 so that the second tilt bracket 33 rotates with respect to the first tilt bracket 32 about the shaft 31. That is, a force larger than the friction generated between the first tilt bracket 32 and the second tilt bracket 33 is applied to the display 11. Thereby, the 2nd tilt bracket 33 rotates with respect to the 1st tilt bracket 32, and the rotation angle of the tilt direction of the display 11 changes in the range of -15 degrees-2 degrees, for example. When the movement of the display 11 is stopped when the angle of the display 11 reaches a desired angle, the display 11 is stopped and held in that position by the friction generated between the first tilt bracket 32 and the second tilt bracket 33.

  When the angle of the display 11 is changed in this way, since the drop moment canceling means 6 is provided, the display 11 can be moved with a small force. That is, the force that the display 11 falls to the front side with the shaft 31 as an axis is canceled by the urging force of the compression spring 63, so that the display 11 does not fall to the front side. For this reason, since the position of the tilt direction of the display 11 can be stopped and held at a desired position with a small friction torque, it is sufficient to apply a small force when moving the display 11, and the display 11 can be easily and smoothly moved. It can be rotated.

  For example, if the display 11 is a liquid crystal television, the position of the center of gravity is in front of the liquid crystal television, so the liquid crystal television tends to fall to the front side. The force that the liquid crystal television falls to the front side is canceled out by the urging force of the compression spring 63. As a result, when no friction is generated between the first tilt bracket 32 and the second tilt bracket 33, if the liquid crystal television is subjected to a force in the direction of rotation about the shaft 31, the liquid crystal television is It pivots back and forth so as to swing around the shaft 31. For this reason, a small friction torque is sufficient to stop and hold the position in the tilt direction of the liquid crystal television at a desired position. Therefore, a small force may be applied to move the display 11, and the liquid crystal television can be rotated. It can be done smoothly.

  Accordingly, the wall-mounted display support mechanism 1 according to the present invention includes the drop moment canceling means 6 that cancels the force that the display 11 tilts to the front side about the shaft 31, so that the display 11 can be moved to a desired position with a small friction torque. The display 11 can be easily and smoothly rotated. Moreover, since the number of parts is small, cost reduction and space saving can be achieved. As a result, the display support mechanism 1 according to the present invention is particularly suitable for holding a stationary display 11 such as a large monitor or a liquid crystal television.

  In addition, since the compression spring 63 is provided so as to extend in parallel to the base plate 2, the distance between the first tilt bracket 32 and the second tilt bracket 33, that is, the distance between the base plate 2 and the mounting plate 4 is reduced. Can do. As a result, the thickness can be reduced. Furthermore, since the first connection bracket 75 for applying the urging force of the compression spring 63 is provided at a position separated from the shaft 31, the compression spring 63 can be reduced in size. That is, since the shaft 31 is supported below the first tilt bracket 32 and the first connection bracket 75 is provided above the first tilt bracket 32, the shaft and the connection member are close to each other. In comparison, the compression spring 63 may have a small torque, so that the compression spring 63 can be downsized. As a result, the thickness can be further reduced.

  In the embodiment of the present invention, the tilt mechanism is provided on one of the two tilt brackets, but the tilt mechanism may be provided on both of the two tilt brackets. The dropping moment canceling means 6 may be provided with a biasing force adjusting means for adjusting the biasing force of the compression spring 63. Further, although the friction generating means 5 and the drop moment canceling means 6 are provided in the first tilt bracket, they may be provided in the second tilt bracket.

  As described above, the display support mechanism according to the present invention includes the base plate, the tilt bracket, the tilt mechanism, and the mounting plate, and the tilt bracket includes the shaft, the first tilt bracket, and the second tilt bracket, and the link mechanism is configured. Since the tilt mechanism is composed of a friction generating means and a drop moment canceling means, the display can be stopped and held at a desired position with a small friction torque, and the display can be smoothly rotated. In addition, since it can be thinned, it is particularly suitable for holding a wall-mounted display such as a large monitor or a liquid crystal television.
