Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a television lifting device for a conference desk that raises and lowers a retractable television set installed on the conference desk.

[Conventional technology]

Some conference desks have televisions built into them, which are stored inside the desk when not in use and raised above the desk when in use to display materials, etc. on the screen.
In this case, the television is generally raised in a straight line until the screen is completely above the desk surface.

[Problem that the invention aims to solve] However, if the screen is completely exposed above the desk surface in this way, the height of the top edge of the TV above the desk surface will be high, and the faces of the participants facing each other will be hidden. So,
This becomes a factor that hinders the progress of discussion.

[Means for solving problems]

This invention consists of a TV mount rotatably supported around a hinge in the TV storage part of a conference desk, a motor with a reducer as a drive source, and a first TV mount provided between the TV mount and the motor. a crank mechanism, a front lid and a rear lid that are divided into two parts, each having a hinge on the front and back edges, and are disposed in the upper opening of the TV housing so as to be openable and closable; the motor and the front lid. and a second crank mechanism that is interlocked with the rotation of the TV mount and provided so that the rotation direction of the front cover is opposite to that of the TV mount, and the crank mechanism is mounted on the TV mount. This device is characterized in that the television is raised until about half of its screen is above the desk surface, the rear lid is pushed up at the upper end of the television, and at the same time the front lid is opened downward.

〔Example〕

This invention will be explained in detail below based on illustrated embodiments.

FIGS. 1 and 2 show an embodiment of this invention, in which the lid of the television storage section 11 of the conference table 10 is divided into two parts in the front and back to form a front lid 12 and a rear lid 13.
2 is provided with a hinge on its front side edge, and the rear cover 13 is provided with a hinge on its rear side edge so that they can be opened and closed freely. A stand 14 is installed on the bottom surface of the storage section 11, and a support 15 is erected on the stand and reinforced with a reinforcing material 16. A television mount 17 is connected to the support 15 via a hinge 18, and a television 19 is placed on the mount 17 and its rear surface is supported by a holding member 20.

A motor 21 with a speed reducer as a drive source is installed on the table 14, and a disc 22 as a connecting arm is fixed to the rotating shaft of the motor 21. A predetermined point on the peripheral edge of the disc 22 and a predetermined point on the television mount 17 are connected by a rod 23. Both connection points are designed to be rotatable. That is, the rotational motion of the motor 21 is converted into a substantially linear motion by a crank mechanism consisting of a disc 22 and a rod 23, and is transmitted to the mounting base 17, and the mounting base 17 is rotated about the hinge 18. There is. As a result, TV 1
9 will stand up at the required angle or fall backwards. In this case, even if the TV 19 is raised at the required angle (in use position), the screen should not be raised completely above the desk surface, but should be raised to about half of the height, and the angle etc. should be adjusted so that sufficient visibility can be obtained. It is set. Further, the rear lid 13 is pushed up by the upper end of the television 19 and opens upward. In that case, the height of the tip of the lid 13 (height from the desk top surface)
is approximately 150mm.

On the other hand, a rod 24 connects a predetermined point of the disc 22 to a substantially central portion of the back surface of the front cover 12. In this case as well, the two connecting points have a rotatable connection structure, and the rotational force of the motor 21 is used to open and close the front cover 12. The opening and closing of this front cover 12 is linked to the raising and lowering of the television 17.

In addition, limit switches 25 and 26 are installed to set the rotation angle of the disc 22, that is, the start and end points of the rotation angle of the television 19, and a protrusion 27 that engages with these limit switches is attached to the disc 22. It is set up in

Next, the operation will be described. 1st in use condition
As shown in the figure, the connection point of the rod 23 on the disc 22 is located close to the television mount 17, and the television 19 is in an elevated state.

At this time, the connecting point of the rod 24 on the disc 22 is at a lower position, and the front cover 12 is rotated downward so that its tip is located near the hinge 18. Further, the rear cover 13 contacts the upper end of the television 19, is pushed up, and is rotated upward. As a result,
The screen of the television 19 appears within the field of view. Even in this state, the height from the desk surface is approximately 150 mm, so the faces of the participants facing each other will not be hidden.

On the other hand, in order to store it when not in use, when an operating switch installed on a desk or the like is pressed, the motor 21 is operated and the disc 22 is rotated. Along with this, the mounting base 17
rotates clockwise about the hinge 18, and the front cover 12 rotates counterclockwise. Then, when the motor 21 is rotated by a predetermined angle, the rotation of the motor 21 is stopped. At this time, as shown in FIG. 2, the television 19 is in the storage section, and the front lid 12 and the rear lid 13 are in a state where their ends are joined, that is, the lids are in a closed state.

In addition to being able to operate it at hand, it can also be operated remotely.

[Effect of idea]

As described above, according to this invention, the lid of the TV storage compartment is divided into front and rear parts, with the front lid opening downward and the rear lid opening upward, increasing the open area and allowing approximately half of the TV screen to be opened. Since the TV was raised to a position above the desk surface, the height of the TV above the desk surface could be approximately 150 mm, which is a height that does not cover the faces of the participants facing each other. Furthermore, since the opening and closing of the lid is linked to the raising and lowering movement of the television and is performed by the same driving source, the mechanism is simplified. Moreover, since the upper and lower positions are determined using the top dead center and bottom dead center of the crank operation, there are advantages in that starting and stopping can be performed smoothly and positional accuracy can be ensured.
