Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television stand device for business use or home use which can change the direction of a screen in the direction of a viewer's line of sight by electric motor, and more particularly, realizes a vertical movement in a large range. The technical feature of the present invention is that not only an independent television stand but also that the housing forms a wall panel or a decoration pillar of a building.

[0002]

2. Description of the Related Art Ideally, an image forming apparatus such as a television is installed with its screen directed in the line of sight of a viewer. In particular, since the liquid crystal type, which has become widespread recently, cannot have a large viewing angle due to the principle of image formation, there is a great demand to make the screen direction coincide with the line of sight. Such a request is more remarkable in a patient who is prohibited from moving and who cannot move freely than in a healthy person.

[0003] In response to such demands, many proposals have been made for television stand devices that are devised so that the direction of the screen can be easily turned to the direction of the line of sight manually or electrically. In general, in order to turn a screen of a television or the like in the direction of the line of sight, it is generally necessary to swing the head vertically and horizontally, and as a representative example of such an operation, for example, a television receiver (See Japanese Utility Model Laid-Open No. 33275/1988).

The gist of the technical contents disclosed in this publication is that a vertical axis and a horizontal axis each having a worm wheel are combined, and each axis is driven by an independent motor which is controlled by a remote controller, so that the vertical axis and the horizontal axis can be adjusted. The point is that the swing motion is realized. The worm gear can rotate the worm wheel with the worm. It is a suitable gear mechanism.

[0005]

The nature of the worm gear, in which the worm is not turned by the worm wheel, does not only act as an advantage, but has the following problems. That is, when the motor stops, a very strong braking force is momentarily applied to the driven object. As a result, there is a danger that the television will slide sideways in the front-rear or left-right direction when the television is operated to be tilted greatly.

This problem is caused by an object moving about a vertical axis or a horizontal axis, specifically, a moving inertial force of a television or the like. One is a method of fixing a leg of a television or the like on a base plate on which the leg is placed. Although this method is effective, it is surprisingly complicated considering the versatility that can be applied to televisions of various sizes. The second is to control the tilt operation of a television or the like at a very low speed. However, this method cannot eliminate so-called frustration complaints. The third is a method of lowering the moving speed of a television or the like required to change the angle of the television or the like in order to lower the moving inertia force since the inertial force of the object is proportional to the square of the speed. This method can be realized by moving the moving object as close as possible to the center of the vertical or horizontal axis. This is because, when the moving object is located at the center of the axis of motion, the action of rotating in place is realized, while the further away from the center of the axis of motion, the closer to the action of swinging at a high peripheral speed. Because it becomes.

[0007] In the control device for a stand for a television receiver disclosed in the above-mentioned publication, there is a concern about a problem due to this phenomenon in the horizontal axis. Although this is not limited to the worm gear, in general, when using a full-shaped gear and trying to drive an object around the shaft of the gear in the circumferential direction of the shaft, the gear itself becomes an obstacle. This is because the moving object cannot be mounted closer to the axial side than the radius of the gear.

[0008] In addition, in the conventional technical range, the television cannot be moved up and down. For example,
The natural line of sight of a patient who can raise the upper body only slightly is obliquely upward.In such a case, it is ideal to move the TV etc. to a considerable height and install the screen diagonally downward. However, such an operation cannot be performed.

[0009] Further, in addition to the ones described in the above-mentioned publications, in a conventional TV stand apparatus, with a large screen of a television,
There is also a problem that the TV stand itself occupies a considerable space in the installation room.

Under such circumstances, the present invention realizes a large range of up / down motion in addition to up / down / left / right swing motions in a TV stand apparatus, and performs a swing motion by moving a heavy object such as a television. By installing it in close proximity to the axis that is the center of the swing motion, dangerous movement due to kinetic inertia other than screen angle change is suppressed, and the TV stand housing is not only an independent TV stand as before but also It is an object of the present invention to be able to take in as a substantial or decorative part of a building component from the viewpoint of space saving.

[0011]

The present invention employs the following structure as means for achieving the object.

[0012] The configuration of the television stand apparatus according to the present invention comprises at least a fixed housing to be installed on the floor, a slider mounted on the fixed housing via a lifting mechanism so as to be vertically movable, a horizontal swing mechanism and a vertical swing mechanism. And a television clamp table to be attached to the slider via the.

[0013] In the television stand apparatus having this configuration,
The television clamp table attached to the slider grips the mounted television and the like, and the television clamp table is moved horizontally and vertically by a horizontal swing mechanism and a vertical swing mechanism interposed between the slider and the slider. The head can be swung. Further, the slider is vertically movable. As a result, the viewer can position the television or the like at an arbitrary height and turn the screen in his or her own direction.

The elevating mechanism in the above-mentioned television stand device includes a feed screw driven by a motor, and a screw bracket screwed to the feed screw and moving up and down with a slider. A swinging shaft, a swinging base attached to the swinging shaft, and a hydraulic swinging cylinder. The vertical swinging mechanism includes a horizontal swinging shaft attached to the swinging base, and the swinging shaft. A vertical swing base attached to the shaft and a hydraulic vertical swing cylinder are provided.The vertical swing cylinder is interposed between the horizontal swing base and the vertical swing base, and the horizontal swing cylinder is between the slider and the horizontal swing base. Can be interposed.

[0015] In the television stand apparatus having this structure, the slider is moved up and down by the feed screw of the elevating mechanism driven by the motor, and the oscillating base is moved by the retreating operation of the rod of the oscillating cylinder of the oscillating mechanism. Can be swung in the horizontal direction around the center. Further, the vertical swing base can swing vertically about the vertical swing axis by the retreating operation of the rod of the vertical cylinder of the vertical swing mechanism. Therefore, the television or the like gripped by the television clamp table can swing up, down, left, and right at any height position.

The raising and lowering mechanism in the above-mentioned television stand device includes a feed screw driven by a motor, and a screw bracket screwed to the feed screw and moving up and down with a slider. A oscillating shaft, a oscillating base attached to the oscillating shaft, and a worm-type sector gear for driving the oscillating shaft. And a vertical swing base attached to the vertical swing shaft, and a worm-type sector gear for driving the vertical swing shaft.

[0017] In the television stand apparatus having this configuration, the oscillating base can oscillate in the horizontal direction by driving the sector gear of the oscillating mechanism attached to the oscillating shaft. The vertical swing base can perform a vertical swing operation by driving a sector gear of a vertical swing mechanism attached to the vertical swing shaft. At this time, a worm-type sector gear that can secure a space on one side of the horizontal or vertical swing axis was used for the horizontal and vertical swing mechanisms. It can be mounted close to the shaft.

The fixed housing of the television stand apparatus of the present invention has a movable housing which is fitted over the top surface of the fixed housing via an extruding mechanism. Can be reached.

In the television stand device having this configuration, the fixed housing is placed on the floor, and the movable housing, which is overlapped, is pressed into contact with the ceiling surface via an extrusion mechanism, so that the movable housing is stretched between the floor and the ceiling. Therefore, even when the housing has a Tallboy design and the range of vertical movement is set to be large, a television or the like can be stably supported.

Further, the fixed casing and the movable casing can form a wall panel as they are.

[0021] The TV stand device of this configuration realizes a wall surface on which a television can be mounted by being incorporated as a wall member when building a building or by using it as a partition member of an existing building. Can be.

Further, the fixed housing and the movable housing may form a decorative column.

The television stand device having this configuration is incorporated as a pillar member when building a building, or
By adding it to an arbitrary location in an existing building, a decorative pillar on which a television can be mounted can be realized.
