Description

[Detailed description of the invention] In the present application, two desk boards are arranged, which are separated into the front and back, and a keyboard, for example, is placed on the front table board, and a television monitor, for example, is placed on the rear table board. This is a device table used for equipment, which improves the operability of the equipment by preventing the image surface of a monitor TV etc. from becoming difficult to see due to external light, etc. An example of this is shown in the drawings below. To be more specific, as is clear from FIG. 1, this table has left and right side plates 3a and 3b which are formed by integrally providing an upper frame 1 and horizontal legs 2 that extend horizontally, and these left and right side plates 3a. ,
Between the upper frames 1 and 1 of 3b, two table boards 4 and 5 are arranged front and rear.

Further, below the table plate between the left and right side plates 3aw3b,
A wall body 6 is provided which connects these and is equipped with an elevating mechanism for individually elevating and lowering the two table plates 4 and 5, respectively.

That is, inside the wall body 6, a pair of upper and lower mounting plates 7.8 whose ends are supported by the left and right side plates 3a and 3b, respectively, are provided horizontally at a required interval. ，
8, there are first threaded shafts 10a to led whose upper and lower ends are rotatably supported by the mounting plates 7 and 8 via bearings 9, respectively, and the lower ends of the threaded shafts lea to 10d, respectively. As shown in FIGS. 5 and 6, the first chain wheels 12a to 12d are fixed to each other, and have a disk shape and have a threaded hole 13 in the diameter direction.
A first elevating body is disposed facing each other in the front and rear.

And screw shafts 10a, 10b and 10c located in the front and rear
The pieces 14.14 which are screwed together with 10d are fitted in the front and rear positions of the first connecting rods 15 and 16, respectively, which are connected from the square pipe. A screw shaft is passed through each through a long hole P in the longitudinal direction.

Of the pair of front and rear pieces 14 and 14 fitted into the connecting rods 15 and 16 respectively in the above, one is movable within the connecting rod 15 and the other is rotatable via the central shaft 14'. Therefore, the connecting rod 15 and the screw shafts 10a and 10 are fitted together.
The relationship between b and b is that when the screw shafts 10a and 10b both rotate in the same direction, the connecting rod 15 moves up and down in a horizontal state, and when the screw 10b screwed with the piece 14 that does not have the center shaft 14' rotates. In this case, the connecting rod 15 tilts vertically about the central axis 14'.

This relationship also applies to the relationship between the connecting rod 16 and the screw shafts 10c and 10d.

At the tips of the connecting rods 15 and 16, inverted-shaped support rods 15' and 16' that rise vertically and then bend further forward are integrally connected. The front table board 4 is attached between ' and 16'.

Further, within the wall body 6, there are support shafts 11a to 11d erected on the lower mounting plate 8, and each of the support shafts 11a to 11d is rotatably attached to the upper end and has a screw hole in the center. A second elevating body consisting of chain wheels J7a to 17 and second screw shafts 18a to 18b that are screwed into threaded holes of the chain wheels to ascend and descend, corresponds to each of the first elevating bodies, respectively. It is arranged as follows.

Of these screw shafts, the screw shafts located in front and behind each other have their upper ends attached to a second connecting rod 19 made of a square pipe.
0, and one of the pivot shafts 20' is movably engaged with a long hole P provided in the longitudinal direction of the second connecting rod 19, so that it can be positioned forward and backward. The relationship between the screw shafts 18a, 18b and one connecting rod 19 is that when the front and rear chain wheels 17a, 17b rotate in the same direction, the connecting rod 19 moves up and down in a horizontal state, and the pivot 20
When the chain wheel 17a screwed into the screw shaft 18 engaged with the elongated hole P is rotated, the connecting rod 19 tilts vertically about the other pivot 20. The same holds true for the relationship between the second connecting rod 19 and the other second connecting rod 19.

The rear table board described above is attached between the left and right connecting rods 19, 19.

On the upper surface of the lower mounting plate 8, there are provided a drive mechanism 21 for rotating one screw shaft 10a and 10c facing each other in the left and right positions, and a drive mechanism for rotating the other screw shaft 10b and 10d. 22, and on the lower surface of the upper mounting plate 7, there is one chain wheel 1 facing left and right.
A drive mechanism 23 for rotating the chain wheels 7a and 17c and a drive mechanism 24 for rotating the other chain wheels 17b and 17d are respectively provided.

As is clear from FIG. 4, the hook drive mechanisms 21 to 24 each include an endless chain 25 stretched between chain wheels, an intermediate wheel 26, a reversible electric motor 27, and this electric motor. a drive wheel 28 that is driven by a motor 27 to provide running motion to the endless chain 25; a base plate 29 that includes the electric motor 27 and the drive wheel 28 and is movably supported with respect to the mounting plate; It is composed of a spring 30 that biases the base plate 29 and keeps the endless chain 25 in a tensioned state at all times.

A switch hook 31 is provided with switches for driving the hook drive mechanisms 21 to 24, respectively.

Reference numeral 32 indicates a keyboard, and reference numeral 33 indicates a monitor television. Although the monitor television 33 may be installed directly on the rear table board 5, as shown in FIG.
The table board 5 has a horizontally elongated slit 34 at the center thereof, and a mounting plate having a size necessary for installing, for example, a television monitor placed on the table board 5, as shown in FIG. Place plate 3
A vertically long slit 36 is formed in each of the slits 36, and a cylindrical shaft 37 having a center hole 37' is passed through the cylindrical shaft 37 at the intersection of the slits 34 and 36, and a nut 38 is screwed into the lower end of the cylindrical shaft 37. By doing so, the mounting plate 35 is attached to the table board 5, and the monitor TV 33 is mounted on the mounting plate 35 in this state.
Set up.

When using this configuration, the mounting plate 35 can be rotated relative to the table plate 5 by loosening the nut 38.
It can also be moved forward and backward as well as in the left and right side plate directions along the slits 34 and 36, thereby allowing the orientation and position of the monitor television 33 on the mounting plate 35 to be changed arbitrarily on the table board 5.

Moreover, the center hole 37' is used for inserting an electric wire cable or the like.

When the front table board 4 is raised or lowered, the drive mechanisms 21 and 2 mounted on the lower mounting plate 8 are operated by operating a switch.
2.

Then, each of the chain wheels 12a to 12d rotates in the same direction, and the connecting rods 15 and 16 at the left and right positions simultaneously move up and down in a horizontal state via the pieces 14, and the front table board 4 moves up and down accordingly.

Furthermore, when one of the drive mechanisms 22 is driven in this state, the left and right connecting rods 15 and 16 tilt vertically about the support shaft 14', thereby adjusting the inclination of the front table board 4. can.

Furthermore, in the above, when the drive mechanism 23.24 installed on the lower surface of the upper mounting plate 7 is driven by a switch operation, each of the chain wheels 17a to 17d rotates in the same direction. The connecting rods 19 and 19 at the left and right positions move up and down simultaneously in a horizontal state via 18d, thereby raising and lowering the table board 5 at the rear.

Furthermore, when one of the drive mechanisms 23 is driven in this state, the left and right connecting rods 19, 19 tilt in the vertical direction about the pivot 20, thereby adjusting the inclination of the rear table board 5.

Furthermore, when the mounting plate 35 attached to the upper surface of the rear table plate 5 via the cylindrical shaft 37 is moved or rotated in the front and back or left and right directions with respect to the table plate 5, It is possible to arbitrarily adjust the front/rear, left/right position, or direction of the monitor television installed in the TV.

Since the present application is configured as described above, by adjusting the rear table board to tilt forward or backward and change its tilting state, light from sunlight or a lighting lamp can be used to illuminate a TV monitor, for example. This prevents the image from entering the screen of the monitor and making it difficult to see the image, and the height position of the rear desk board relative to the front desk board can be adjusted arbitrarily, making it easy to adjust the height of the monitor TV, for example. It is extremely convenient to use because it can be set at a position that is most easily visible to the user, and has the advantage of improving the operability of the equipment.
