Description

  The present invention relates to a turning device for a thin display and a display support device.

  Japanese Patent Application Laid-Open No. 8-314386 introduces a display stand provided with a turning mechanism for adjusting the horizontal rotation angle of a thin display screen. According to the publication, the stand portion of the thin display device includes an elastic friction member disposed between the rotating portion at the lower end of the support arm and the pedestal, and a lock lever including a braking member that pressurizes and holds the elastic friction member. The elastic friction member can be released and rotated by operating the lock lever.

  It is also known to facilitate the turning / resting operation of the turning portion by applying an appropriate braking force to the turning portion of the equipment. For example, in Japanese Patent Laid-Open No. 11-166346, instead of a conventional turning restraining mechanism using a coil spring, a turning restraining mechanism using a combination of a ring with a hub and a brake cylinder that closely fits the ring with the hub is provided. It has been introduced.

JP-A-8-314386 Japanese Patent Laid-Open No. 11-166346

  As described above, it is thought that by providing various types of turning suppression mechanisms to the thin display, the usability of the stand for the thin display is improved, but it is possible to withstand a large force acting on the horizontal rotation shaft. Must be configured. In particular, large and heavy liquid crystal displays and plasma displays for TV use add weight to speakers and various interfaces in addition to the weight of the panel itself and substrate, making it more difficult to adjust the orientation of the panel surface. When rotating, a large force acts on the rotation shaft in the left-right direction.

  Further, the above-described turning suppression mechanism should not impair the space saving property of the thin display, and is preferably lightweight. Therefore, it is difficult to employ a large swivel or the like found on a pan head or the like of an existing camera.

The friction plate has the main shaft hole and a turning restriction shaft hole, and is fixed to the bracket member side. The spring member presses against the friction plate on the base member side to suppress a sudden turning.

  According to the second aspect of the present invention, the bracket member of the turning device for the thin display described above has an arcuate turning restriction for restricting a movable range of the turning hole for inserting the main spindle and the turning restriction shaft inserted. And the base member has the main shaft hole and the turning restriction shaft hole, and the friction plate has the main shaft hole and the turning restriction shaft hole, and is fixed to the base member side. It can be replaced with a configuration. That is, it is possible to adopt a configuration in which the bracket member and the base member of the above-described thin display turning device are vertically displaced.

  According to a third aspect of the present invention, there is provided a thin display support device including the thin display turning device described above. The thin display support device includes a turning device for the thin display described above, a mounting bracket for the thin display fixed to the bracket member side, a support member for supporting the thin display, and at least a central portion and screw holes on the outside thereof. And an intermediate plate member disposed between the base member and the support member. Further, the thin display support device is configured such that the intermediate plate-like member is screwed to the upper end of the support member from above with a screw hole in the central portion of the intermediate plate-like member, and a screw in the central portion of the intermediate plate-like member is provided. The turning device of the thin display can be screwed from below with a screw hole outside the hole, and can be assembled.
