Description

[Detailed explanation of the invention] [Industrial application field] This invention is a CRT installed at reception counters, etc.
This invention relates to a mounting device for a display monitor.

[Conventional technology]

CRTs traditionally installed at reception counters, etc.
Various moving mechanisms for moving a display monitor back and forth or left and right, and elevating mechanisms for raising and lowering the monitor have been proposed, and some are in practical use.

Most of the moving mechanisms are, for example, ones that attach wheels to the mounting base of the display monitor, and the wheels are supported and guided by rails, etc., and the elevating mechanism is such that the mounting base is connected to a pantograph-like link, etc. There is one that is supported by a drive cylinder or a feed screw, and is moved up and down by the action of a drive cylinder or feed screw.

[The problem that the idea attempts to solve]

However, since the above-mentioned moving mechanism and elevating mechanism are provided with a display monitor such as a CRT fully exposed on a top plate, it is sufficient that their operating accuracy is quite rough; Maintenance can be easily performed by removing the CRT etc. from its mounting stand, but if the CRT is installed on the bottom side of the top plate so that the display surface of the display monitor matches the surface of the top plate. In some cases, the mounting platform for CRTs, etc. can be simply raised and lowered,
Alternatively, there is a problem that simply being able to move is insufficient.

In other words, it is necessary to raise and position the display surface of the CRT in a symmetrical direction with respect to the surface of the top plate, or to perform maintenance by pulling out the CRT body provided on the bottom surface of the top plate. This is because in some cases, conventional lifting/lowering and moving mechanisms may not be able to handle the situation.

In consideration of these points, the present invention has been developed with additional features such as the ability to finely adjust the orientation of the CRT display in the vertical direction, and the ability to pull out the CRT outside for maintenance even if it is located on the underside of the top plate. The object of the present invention is to provide a mounting device for a display monitor such as a CRT that is equipped with functions.

[Means to solve the problem]

The structure of the present invention for solving the above problem is that a lower board 2 is disposed on a side plate or the like provided on a counter etc. via a suspension member 1 so as to be able to move forward and backward.
An upper board 4 is mounted on this board 2 via an extendable link mechanism 3 such as a pantograph.
, an expansion/contraction drive section 5 of the link mechanism, which is attached to the link mechanism 3 and is made up of a screw member and a nut member that expands and contracts the mechanism; It consists of a support plate 6, and a display monitor mounting stand 7 which is mounted on the upper surface of the support plate 6 through adjusters at its four corners and is equipped with means for fixing the main body of the display monitor such as a CRT. The mounting platform 7 can move up and down and back and forth integrally with the upper and lower substrates 2 and 4 by the action of the upper and lower substrates 2 and 4, and can also move slightly above the upper substrate 4 in the left-right and front-back directions as well as in the height direction of the four corners. It is characterized by the following.

[Effect]

The suspension member moves the display mount forward and backward, and the link mechanism and the telescopic drive section move the display mount up and down.

The height of the above-described pedestal frame can be finely adjusted by an adjuster on a support plate provided on an upper substrate that moves forward and backward, and can be moved up and down, and its front and rear and left and right positions can also be finely adjusted by fixing means.

A through hole for the bolt 7a was formed in the upper surface of the
A CRT mounting stand 7 is mounted thereon, and this stand 7 is formed to be clamped and fixed to the seat 7b by a fixing nut 7c screwed onto the bolt 7a.

That is, the CRT mounting stand 7 is formed so that the degree of inclination on the plane can be finely adjusted by adjusting the upper and lower positions of each seat 7b with each stud bolt 7a.

The above forms an example of the device of the present invention,
This device is provided as a CRT mounting device for a display monitor disposed at a reception counter, etc., as shown in FIG. 4, for example.

In FIG. 4, reference numeral 11 denotes a top plate of the counter, and a display window 11a to which a display screen 10a of a CRT 10 is adapted is formed on this top plate. 11b is a decorative frame for this hole 11a, and 11c is an anti-glare screen.

Reference numeral 12 denotes a side panel that supports the top plate of the counter and functions as a leg.In the device of the present invention, by attaching the suspension member 1 to this panel 12, the suspension member 1 is attached to the bottom side of the top plate 11 of the counter. It will be installed.

The wiring duct 13b provided on the back of the front panel is a front baseboard member provided below the front panel.

The CRT 10 is placed on the CRT mounting stand 7 with its screen 10a facing upward, and this placement is carried out in the following manner.

That is, when the handle 5f is rotated, the mounting platform 7 is positioned at the lowered position by the action of the link mechanism 3 and its elevating mechanism 5, and the device of the present invention moves the suspension member 1 together with the upper and lower substrates 2 and 4. The action causes it to be pulled out to the front of the counter.

Here, the CRT 10 is placed on the mounting stand 7 in the above-mentioned position, and the device of the present invention is pushed directly under the bottom surface of the top plate.

Next, the CRT 10 is raised by rotating the handle 5f, and the fit between the screen 10a and the decorative frame 11b is checked. At this time, the screen 10a and the frame 11
If the asymmetrical contact with the frame 11b is asymmetrical, if the content of the asymmetry, that is, the degree of inclination between the screen 10a and the frame 11b is inconsistent, loosen the fixing nut 7c and adjust which of the four seats 7b. The degree of inclination of the screen 10a can be adjusted to match the frame 11b by changing the direction forward or backward.
1b, the mounting table 7 can be adjusted to the frame 11b by loosening the fixing knob 4b or 64b and slightly moving the mounting table 7 back and forth or left and right. When these fine adjustments are completed, each fixing nut 7c and knobs 4b, 64b are tightened, the handle 5f is removed from its mounting portion 5e, and the handle 5f is reversed and mounted on the mounting portion 5e.

At this time, by supporting the handle of the handle 5f which has been turned in the opposite direction on the handle receiver 14 in which the fitting portion 14a is formed, the screw member 5c is locked so that it cannot be rotated without permission (fifth
(see figure). Although the locking mechanism of the screw member 5c is here attached to the lower substrate 2, its attachment position is not limited to this example. For example, as shown in FIG. 6, the lower substrate 2 is extended toward the front (right side in the figure) to form a lock bar receiver 14', and a lock bar 5f' insertion hole 14 provided therein is formed.
Rotation of the screw member 5c may be prevented by inserting a lock bar 5f' into a'. 6th
In the figure, 5g is a retaining screw for lock bar 5f'.

[Effect of idea]

In this way, the device of the present invention can tightly fit the display screen of the CRT 10 into its display window 11a, so it can be deployed as if the CRT was fixedly mounted on a counter, and Even if there is some roughness in the assembly accuracy or installation accuracy of the invented device, this does not pose a problem and is extremely useful in manufacturing or assembling the device.

Moreover, when the CRT itself needs maintenance, it can be easily pulled out of the counter, even though it appears to be integrated with the counter, making it extremely convenient in this respect as well.
