Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stand with a tilt function, and more particularly to a stand with a tilt function that is optimal for a flat display (hereinafter abbreviated as FD).
[0002]
[Prior art]
In recent years, personal computers (hereinafter abbreviated as “PCs”) have become very popular in offices, and recently, have also become popular in homes.
[0003]
However, CRTs are generally used for PC displays. According to this, the desk top surface often occupies a large area, and there is a disadvantage that work other than the PC cannot be performed. The FD that can be used is frequently used instead of the CRT.
[0004]
[Problems to be solved by the invention]
Since this FD is thin and lightweight, it can be used on the desk top surface in various ways. The FD is used while being frequently operated from a vertical state to a horizontal state depending on the situation. Yes.
[0005]
This new product, FD, has few peripheral devices according to the application, for example, a device that operates the display screen from vertical to nearly horizontal and fixes it in an appropriate position. It is becoming.
[0006]
[Means for Solving the Problems]
The present invention has been made to provide a stand with an FD tilt function in order to meet these demands, and can change the FD from a substantially vertical screen position to a screen position at an angle close to horizontal with one touch. In other words, many people can see the same screen at the same time when necessary.

[0008]
According to a second aspect of the present invention, in the first aspect of the present invention, the bracket is supported by a rotation support means that is rotatable in a horizontal plane on a base plate that can be placed on a table surface. .
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to the embodiments shown in FIGS.
[0010]
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 1a and 1a are formed on the upper portion of a bracket 1 which is erected and spaced apart on the left and right. These support portions 1a are each provided with support holes 2 and 2 on the same axis. The first shaft 3 is inserted through the support holes 2 and 2 so as not to rotate. In this case, the structure that is inserted in a non-rotatable manner is such that the first shaft 3 has a flat surface portion 3a in which a part of a circular shape is cut off in the longitudinal direction, and the support hole 2 is not a perfect circle but the first shaft 3 This is because the hole shape matches the cross-sectional shape.
[0011]
The first shaft 3 between the support holes 2 and 2 of the bracket 1 is rotatably fitted with a first bearing portion 4a serving as a base end of an arm 4 having a flat plate-like length.
[0012]
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, 6a formed on the left and right sides, and these support portions 6a. Are provided with support holes 7 on the same axis.
[0013]
The second shaft 8 is inserted through the support holes 7 and 7 so as not to rotate. This non-rotatable structure has a flat surface portion 8a in which a part of a circular shape is cut off in the longitudinal direction of the second shaft 8 in the same manner as the relationship between the first shaft 3 and the support hole 2. The support hole 7 is not a perfect circle, but has a hole shape that matches the cross-sectional shape of the second shaft 8.
[0014]
A second bearing portion 4b serving as a tip of the arm 4 is rotatably fitted to the second shaft 8 between the support holes 7 of the mounting bracket 6.
[0015]
The first shaft 3 has a large gear 9 having an appropriate number of teeth at the outer position of the bracket 1, and the second shaft 8 has a larger number of teeth at the outer position of the support hole 7 of the mounting bracket 6 than the large gear 9. The small gears 10 having a small number are fitted and fixed, and an endless toothed belt 11 that meshes with the teeth of both gears is wound between the large gear 9 and the small gear 10.
[0016]
The first shaft 3 and the large gear 9 are fixed to each other by screwing a screw 12 from the outside of the boss portion of the large gear 9 into the flat portion 3a formed on the first shaft 3 and abutting the tip thereof. The two shafts 8 and the small gears 9 are similarly fixed by screwing screws 13 from the outside of the bosses of the small gears 10 into the flat portion formed on the second shaft 8 and abutting the tips thereof.
[0017]
In addition, torsion springs 14 and 14 are attached to the first bearing portion 4a to lift the arm 4 lightly. One end of the spring 14 is on the inner side of the bracket 1 and the other end is on the arm 4. Each is locked.
[0018]
The mounting bracket 6 is provided with a brake cover 15 that covers the second bearing portion 4b at the tip of the arm 4. The cover 15 controls the weight when the arm 4 is operated from the outside. A brake screw 16 is screwed. The brake screw 16 has a knob 16b at the outer end of the screw rod 16a, and the rotation of the arm 4 is braked by turning the knob 16b and pressing the tip of the screw rod 16a against the outer periphery of the second bearing portion 4b. Has been made.
[0019]
In the figure, reference numeral 5 a is a display surface of the display 5, 17 is a cover of the bracket 1, and 18 is an arm cover including the toothed belt 11.
[0020]
2, the bracket 1 is placed on the table surface 19 so that the upper surface of the base plate 21 placed at the corners via the rubber legs 20 and the center of the bracket 1 are in a horizontal plane. Is supported by a rotation support means 22 using a rotor such as a ball or a roller provided between the bracket 1 and the bottom plate 1b of the bracket 1. The bracket 1 and the base plate 21 are integrated by a fastening means 23 such as a bolt serving as a rotation shaft at a vertical rotation center.
[0021]
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 into a horizontal state from this state, when the operation is performed to gradually lower the tip of the arm 4, the arm 4 is rotated downward about the first bearing portion 4a by this operation. The bearing portion 4b is lowered.
[0022]
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, but the small gear 10 is integrated with the display 5 via the mounting bracket 6. 4 can rotate freely.
[0023]
This means that when the arm 4 is lowered, the endless toothed belt 11 that meshes 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. become. If the number of teeth of the large gear 9 is twice 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. 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 when the display 5 is in a horizontal state.
[0024]
FIG. 3 shows the change in the position of the second shaft 8 of the mounting bracket 6 with respect to the lowering of the arm 4 at a certain angle, in order, and in the final stage, matches the position shown in FIG. In the case of the embodiment, it is shown that if the arm 4 is rotated by 67 °, the display 5 can be rotated by 75 ° from the vertical state and can be tilted close to the horizontal state. If the orientation of the display 5 is to be changed, the orientation can be set by changing the rotation support means 22. Furthermore, the present invention is not limited to a display as an object, and can be used even for other objects.
[0025]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
1) In the case of a display, the surface can be set at an arbitrary angle from a vertical position to an almost horizontal position. Therefore, especially in a meeting where many people gather, the display surface can be viewed by a person on the back side in a vertical posture. Although it is not possible, it is very convenient that almost everyone can look in at the same time by using the horizontal posture.
[0026]
2) The arm angle can be set appropriately according to the angle of the surface of the object such as a display.
[0027]
3) According to claim 2, the bracket can be rotated with respect to the base surface, so that the surface of the object such as a display can be set in a desired direction.
