Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support device pivot for supporting a thin display such as a supporting arm or a stand on a supporting device such as a supporting arm or a stand so that the supporting device can be tilted vertically. Bearing structure

[0002]

2. Description of the Related Art As a supporting arm or a stand for supporting a thin display, a flat display device disclosed in Japanese Patent Laid-Open No. 4-15680 and an information monitor device described in Japanese Patent Laid-Open No. 9-326980 are proposed. Has been done.

The former flat display device is a device for supporting the flat display on the tip of a bendable arm portion, and the arm portion can be bent to adjust the position of the flat display supported on the tip portion. It is the one.

The latter information monitor device is a device in which both ends of a column are brought into contact with and fixed to a ceiling and a floor, and a thin plate-shaped information display unit is held on the column so that the vertical position can be adjusted.
In addition to supporting the information monitor using an articulated arm, this device can also directly connect the thin monitor to the column via a joint that bends vertically and horizontally.

[0005]

In order to fix a thin display or the like at a constant angle with a supporting arm, an articulated arm, or the like used in a conventional supporting device, a bending portion for adjusting the angle is used. Corresponding support strength is required. However, when the strength of the bent portion is increased, it is difficult to adjust the angle of a thin display or the like.

That is, when the vertical angle is adjusted by operating a thin display or the like, if the bending portion is weakened to facilitate the angle adjustment, the thin display or the like may face downward due to its own weight. On the other hand, if the support strength of the bent part is increased to withstand the weight of the thin display etc., the angle adjustment operation becomes heavy, and once the fixing screw etc. that fixes the angle of the bent part is released, it can be adjusted to any angle. After that, it might be necessary to tighten the fixing screw again.
As described above, heretofore, there has not been proposed a device capable of easily adjusting the vertical angle while supporting a large-sized thin display or the like on a supporting device such as a supporting arm or a stand.

Therefore, the present invention was created to solve the above-mentioned problems, and facilitates the vertical angle adjustment operation of a thin display or the like supported by a supporting device, and particularly supports a supported object such as a large thin display. Even in such a case, it is an object of the present invention to provide a pivot bearing structure for a supporting device in which the supported body does not face downward due to its own weight and the operation does not become heavy.

[0008]

In order to achieve the above-mentioned object, the first means of the present invention is mounted on a supporting device having a rod-shaped supporting arm P, and connects a supported object Q at a vertical angle. In the support device pivot bearing structure, a large pressure bonding plate 1 for sandwiching the end P1 of the support arm P from the left and right and a fixture 4 for connecting the supported object Q are provided, and the end of the support arm P is subjected to large pressure bonding. A pair of support pieces 3 sandwiched from the outside of the plate 1
A small crimping plate 2 arranged inside each of the
With the latch mechanism 10 provided via the large-sized crimping plate 1 and the large-sized crimping plate 1, the support piece 3 and the small-sized crimping plate 2 are in sliding contact when the supported body Q is adjusted upward, and the supported body Q is adjusted downward. This is because the large pressure plate 1 and the end P1 of the support arm P are sometimes provided in sliding contact with each other.

In the second means, the latch mechanism 10 is
Disc-shaped latch claws 11 fixed between the large-sized crimping plate 1 and the small-sized crimping plate 2 so as to project in the outer peripheral direction of the large-sized crimping plate 1 are provided on the fixture 4. The locking plate 12 is engaged with the latch claw 11 when the supported body Q is adjusted downward.

The large pressure bonding plate 1 and the small pressure bonding plate 2 in the third means are made of a synthetic resin material. And
In order to solve the problem, the large-sized crimping plate 1 and the small crimping plate 2 are crimped between the supporting piece 3 and the supporting arm end portion P1 by the bolt-shaped tightening shaft 5 penetrating the supporting pieces 3 with each other. Use it as a means.

According to the present invention, the downward load due to the weight of the supported body Q such as a thin display is held by the large pressure plate 1 and the small pressure plate 2 via the latch mechanism 10. On the other hand, when the supported body Q is lifted upward, the latch mechanism 10 is released and the support piece 3 and the small crimping plate 2 only come into sliding contact, so that the angle can be adjusted with a slight force. .
