DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS.

FIG. 1 is an exploded perspective view of components of a stand with a tilt function according to the present invention. A pair of support portions formed at right and left intervals on an upper portion of a bracket 1 that is erected. 1a, 1a, and these support portions 1a are provided with support holes 2, 2 respectively on the same axis. The first shaft 3 is inserted through the two support holes 2 and 2 so as not to rotate. In this case, the structure in which the first shaft 3 is non-rotatably inserted has a flat portion 3a in which a part of a circular shape is cut off in the longitudinal direction.
This is because the hole shape matches the cross-sectional shape of the shaft 3.

A first bearing 4a, which is the base end of a flat arm 4 having a predetermined length, is rotatably fitted to the first shaft 3 between the support holes 2 and 2 of the bracket 1. .

On the other hand, a mounting bracket 6 is fixed to the back surface of the display 5 as an object, and the mounting bracket 6 has a pair of support portions 6a, 6 formed at right and left intervals.
The support portions 6a have support holes 7, 7 respectively.
Are provided on the same axis.

A second shaft 8 is inserted through the support holes 7, 7 so as not to rotate. The structure that cannot be rotated is
Similarly to the relationship between the first shaft 3 and the support hole 2, the second shaft 8
Has a flat portion 8a in which a part of a circle is cut off in the longitudinal direction, and the support hole 7 is not a perfect circle but a hole shape that matches the cross-sectional shape of the second shaft 8.

A second space between the support holes 7, 7 of the mounting bracket 6 is provided.
A second bearing 4b, which is the tip of the arm 4, is rotatably fitted to the shaft 8.

A large gear 9 having an appropriate number of teeth is provided on the first shaft 3 outside the bracket 1, and the large gear 9 is provided on the second shaft 8 outside the support hole 7 of the mounting bracket 6. Small gears 10 having a small number of teeth are fitted and fixed respectively, and an endless toothed belt 11 meshing with the teeth of both gears is wound between the large gear 9 and the small gear 10.

The first shaft 3 and the large gear 9 are fixed to each other by screwing a screw 12 into the flat portion 3a formed on the first shaft 3 from outside the boss portion of the large gear 9 and abutting the tip thereof. The second shaft 8 is fixed to the small gear 9 similarly.
The screw 13 is screwed into the flat portion formed from the outside of the boss portion of the small gear 10 and the tip thereof is abutted.

The first bearing 4a is fitted with torsion springs 14, 14 for lightly lifting the arm 4, one end of which is inside the bracket 1 and the other end. Each is locked to the arm 4.

The mounting bracket 6 is provided with a brake cover 15 for covering the second bearing portion 4b at the tip of the arm 4. The cover 15 controls the weight of the arm 4 when the arm 4 is operated from the outside. Screw 16 is screwed into the brake. The brake screw 16 has a knob 16b at the outer end of a screw rod 16a.
The rotation of the arm 4 is braked by pressing the tip of the threaded rod 16a against the outer periphery of the second bearing portion 4b by turning 6b.

In the figure, reference numeral 5a denotes a display surface of the display 5, 17 denotes a cover of the bracket 1, and 18 denotes an arm cover including the toothed belt 11.

The bracket 1 is mounted on a table surface 19 as shown in FIG. 2 so that the upper surface of a base plate 21 mounted on a corner via rubber feet 20 and the center of the bracket 1 can be installed. Are supported by a rotation support means 22 of a rotor such as a ball and a roller provided between the bracket 1 and the bottom plate 1b so as to be rotatable in a horizontal plane.
The bracket 1 and the base plate 21 are integrated by a fastening means 23 such as a bolt serving as a rotation axis at a vertical rotation center.

Next, the operation of the above embodiment will be described. As shown in FIG. 2, the display 5 is normally supported in a vertical state. In order to bring the display 5 to the horizontal state from this state, the tip of the arm 4 must be gradually lowered, and this operation causes the arm 4 to move to the first bearing portion 4a.
And the first bearing portion 4b
Descends.

At this time, the large gear 9 is fixed to the bracket 1 and the small gear 10 is fixed to the mounting bracket 6 so as not to rotate, and does not move, but the small gear 10 is integral with the display 5 via the mounting bracket 6. Therefore, it can freely rotate with respect to the arm 4.

This means that when the arm 4 is lowered, the endless toothed belt 11 meshing with the teeth of the two gears 9 and 10 slightly rotates to rotate the small gear 10 around the second shaft 8 of the mounting bracket 6. Will be moved. Here, if the number of teeth of the large gear 9 is twice as large as the number of teeth of the small gear 10, the rotation angle of the second shaft 8 is twice the rotation angle of the first shaft 3, thereby causing the display 5 to rotate. The speed of transition from the vertical state to the horizontal state is accelerated as compared with the case where the toothed belt 11 is not used. Reference numeral 5 'indicates that the display 5 is in a horizontal state.

FIG. 3 sequentially shows a change in the position of the second shaft 8 of the mounting bracket 6 with respect to the descent of the arm 4 at certain equal angles. In the final stage, the position coincides with the position shown in FIG. In the case of this embodiment, if the arm 4 is rotated by 67 °, the display 5 can be rotated by 75 ° from the vertical state and tilted to be almost horizontal. When it is desired to change the direction of the display 5, the direction can be changed by the rotation support means 22 and set to an arbitrary direction. Further, the present invention is not limited to a display as an object, and can be used for other objects.

[0025]

As described above, the present invention has the following advantages. 1) In the case of a display, its surface can be set at an arbitrary angle from a vertical position to a substantially horizontal position. Therefore, especially in a meeting where many people gather, a person on the back side can see the display surface in a vertical position. Although it is not possible, it is extremely convenient that almost all people can look in at the same time by adopting the horizontal posture.

2) The arm angle can be set to an appropriate angle according to the angle of the surface of an object such as a display.

3) According to the second aspect, since the bracket can be rotated with respect to the base surface, the surface of the object such as the display can be set in a desired direction.
