Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a flat type display support device, and more particularly to a display support device that enables use of a touch panel type flat display.
[0002]
[Prior art]
In recent years, the application range of personal computers has been dramatically expanded, and personal computers are being used for daily work on ordinary office desks.
[0003]
The above-mentioned personal computer display does not take up installation space on the desk and is often used for an operator's eyes. Since this type of thin liquid crystal display is not self-supporting, it can be attached to the tip of a support arm that is pivotally supported in a horizontal plane on a base fixed to the desk, and the liquid crystal display can be viewed in any position and orientation. A support device having a swivel arm structure that can be swung and stored in a position that does not interfere with other duties when not in use is used.
[0004]
[Problems to be solved by the invention]
However, recently, a display device using a liquid crystal display that is operated by directly touching the screen has been realized. When using such a touch panel type display supported by a support device using a conventional swivel arm, when touching the screen, The support arm swirled, so that it was not possible to perform touch operations to support it in an easy-to-read state, and there was no choice but to use it fixedly standing upright without stopping.
[0005]
According to the present invention, even when a touch panel type liquid crystal display is supported by a support device using a swing arm, the display does not move at the time of touch, and a reliable touch operation can be performed. An object of the present invention is to provide a touch panel type flat display supporting device.
[0006]
[Means for Solving the Problems]
As a means for solving the above-mentioned problems, the present invention is a display support device in which a plurality of arms are connected to a fixedly installed base so as to be able to bend and swivel in a horizontal plane, and the display is supported at the tip of the most advanced arm. In the connecting portion between the base and each arm, a shaft is provided on one side, and a bearing portion that is rotatably fitted to the shaft is provided on the other side, and a predetermined frictional force is applied between the shaft and the bearing portion. At least one of the upper and lower surfaces of the plate that is fitted to a small diameter portion of the shaft portion that is non-rotatably coupled to the upper end of the lower shaft in each of the coupling portions. And a friction unit, and the plate is constituted by a torque unit that is fixed to the bearing portion side of the connecting portion by screwing or the like . The above frictional force is such that the arm does not rotate during touch operation but can be rotated during use or storage, and actually withstands a pressing force of about 1.0 to 2.0 kg.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to embodiments shown in the drawings.
[0009]
FIG. 1 is a perspective view showing an example of a use form of the present invention, and FIG. 2 is a side view showing a plurality of bases 4 fixedly erected on a top plate 2 of a desk 1 via a clamp 3. Display arms that support a liquid crystal flat display 8 (hereinafter simply referred to as a display) including a touch panel type at the tip of the most advanced arm 7. Parts are provided.
[0010]
Since the configuration of the display support portion is the same as that of the prior art, the details thereof are omitted. However, the arm 7 has a substantially L-shaped display cradle 10 that is supported by a horizontal shaft 9 so as to be tiltable by a horizontal shaft 9. The back surface of the display 8 is fixed to the vertical surface portion 10a of the cradle 10 with screws or the like.
[0011]
A friction generating device 14 is provided at each of the connecting portions 11, 12, 13 of the base 4 and the arms 5, 6, 7 to give a predetermined friction when each arm is turned.
[0012]
As an example of the friction generator 14, the connecting portion 12 between the arms 5 and 6 is shown in an exploded perspective view in FIG. 3, and as shown in a sectional view in the assembled state in FIG. It is comprised by the torque unit 17 interposed between the shaft 15 protruding upwardly by the front-end | tip part of this, and the bearing part 16 formed in the base of the upper arm 6. As shown in FIG.
[0013]
As shown in FIG. 5, the torque unit 17 includes a shaft portion 20 having a flat engagement portion 19 at the lower end that fits into a slit 18 cut in the axial direction from the upper end of the shaft 15; Friction comprising a plate 23 fitted to the small diameter portion 21 at the upper portion of the shaft portion 20 and fixed to the step portion 16a of the bearing portion 16 by screws 22 and a corrugated washer attached to at least one surface of the play 23. A plate 24 and a head 25 fixed to the upper end of the shaft portion 20 by screwing or the like to set the friction force of the friction plate 24 are configured. This frictional force is set so that the pressing force required to turn the arm 6 is about 1.0 to 2.0 kg.
[0014]
A small-diameter portion 26 is formed in the middle of the shaft 15, and the tip of a set screw 27 screwed from the screw hole 16 b on the side portion of the bearing portion 16 of the upper arm 6 is fitted into the small-diameter portion 26. Thus, the upper arm 6 is prevented from coming off.
[0015]
In the figure, 28 is a cap that is screwed onto the upper end of the bearing portion 16 of the upper arm 6 and closes, and 29 is a washer interposed at the lower end of the bearing portion 16.
[0016]
The above-described configuration is the same for the connecting portion 11 between the base 4 and the arm 5 and the connecting portion 13 between the arms 6 and 7.
[0017]
Therefore, even if the touch panel type liquid crystal display 8 is attached to the cradle 10 of the state-of-the-art display support part and the screen is touch-operated, the brakes are applied by the torque units 17 of the connecting parts 11, 12, 13, so The arms 7, 6 and 5 are not swung when touched by the above, and the touch operation is made possible.
[0018]
When the display 5 is not used, the arms 5, 6 and 7 are rotated to change the position or to be in the retracted state. When the display 8 is pressed firmly, the connecting portions 11, 12, 13 of the arms 5, 6, 7 are pressed. Can be turned against the frictional force of the torque unit 17, and the display 8 can be moved to a desired position.
[0019]
When it is desired to increase or decrease the frictional force, a desired value can be selected according to the tightening amount of the head 25 of the torque unit 17. If a general display other than the touch panel type is attached, it can be used in the same manner as a conventional support arm.
[0020]
Further, when a general display is attached to form a normal light rotation operation, it can be achieved by removing the torque unit 17 by removing the screw 22 fixing the torque unit 17.
[0021]
From the viewpoint of usage and operation, some of the connecting portions 11, 12, and 13 can be configured not to rotate. In this case, the set screw 27 of the bearing portion 16 may be replaced with a long one, and the inside thereof may be pressed against the shaft 15.
[0022]
According to the combination of the above configurations, any of the configuration in which each of the connecting portions 11, 12, and 13 is rotated lightly according to the use of the display and the place where it is used, the configuration that rotates with a predetermined torque, and the configuration that does not rotate are easy. It can cope and can give mediocreity.
[0023]
【The invention's effect】
As described above, according to the present invention, the touch panel type liquid crystal display can be operated without touching the touch panel type liquid crystal display while being supported by the arm. Similar to the support arm, the display can be moved to any desired position.
