<Operation of this embodiment>
The operation of the above-described table T will be described below.

  First, by operating the operation switch 33 on the right end portion 2a of the tilt top plate 2, the left and right legs 31 can be extended and contracted in synchronization with each other. When both legs 31 expand and contract, the left and right bases 1 supported by these legs 31 move up and down together with the connecting beam 6. As a result, the tilt top plate 2 pivotally supported by these bases 1 moves up and down. Therefore, the height position of the tilt top plate 2 can be freely changed by operating the operation switch 33. Since the fixed shelf board 5 and the panel 8 are attached to the base 1 and the wiring duct 7 is attached to the connecting beam 6, the height of the fixed shelf board 5, the panel 8 and the wiring duct 7 is high. The position can also be changed at the same time while maintaining the relative positional relationship with the tilt top plate 2. 1 to 6 show a state in which the legs 31 are shortened to lower the tilt top 2 to the sitting position D, and FIGS. 7 to 10 extend the legs 31 to tilt the top 2. It shows a state in which is raised to the standing position U.

  Further, the locked state of the left and right gas springs 41 can be released by operating the operation body 42 provided at the center of the tilt top plate 2 in the left-right direction, and the tilt position of the tilt top plate 2 can be changed. Becomes That is, as shown in FIGS. 22 and 23, when the operation lever 422 of the operation body 42 is rotated from the locked position shown by the solid line to the unlocked position shown by the imaginary line, the operation force is transmitted through the two wires w. Is transmitted to the left and right gas springs 41, and the locked state of the gas springs 41 is released. Specifically, the operating lever 422 of the operating body 42 is rotated by pulling it forward from the locked position shown by the solid line in FIG. 22 to the unlocked position shown by the imaginary line, whereby the pressing lever 418 on the gas spring 41 side is rotated. Will rotate from the non-operating end pressing position shown by the solid line to the operating end pressing position shown by the imaginary line, and the gas spring 41 will be in the unlocked state. In this state, as shown in FIG. 23, the operating lever 422 can be held in the unlocked position while the used end 2b of the tilt top plate 2 is gripped from above and below. Therefore, the tilted top plate 2 can be tilted from the horizontal position h to the tilted position s by pushing down the use end 2b portion of the tilted top plate 2 in this gripped state. This tilting operation is performed against the repulsive force of the gas spring 41, and the repulsive force is accumulated in the gas spring 41. On the other hand, when the force of pushing down the tilt top plate 2 in this gripping state is loosened, the tilt top plate 2 rotates in the direction of returning to the horizontal posture h by the repulsive force of the gas spring 41. Therefore, the tilt angle of the tilt top plate 2 can be freely changed by adjusting the pressing force while holding the use end 2b of the tilt top plate 2. Then, when the finger is released from the operation lever 422 when the tilt top 2 reaches the desired tilting position, the operation lever 422 self-returns to the original lock position and the gas spring 41 enters the locked state, and the tilt top 2 The tilt operation of is prohibited. 5, FIG. 6, FIG. 9 and FIG. 10 show a state in which the tilt top plate 2 is tilted and locked to the maximum tilt posture s.

<Operation and effect of this embodiment>
With such a configuration, since the height position and the tilt position of the tilt top plate 2 can be freely changed and used, the usage state and the standing position in the sitting position D performed by sitting on a chair can be used. It is possible not only to freely select the manner of use at the standing position U, but also to arbitrarily change the tilt angle of the tilt top 2 at each height position. That is, according to the table T, the height and inclination of the tilt top plate 2 can be freely set according to the physical characteristics of the user, the work content, and the like, and the setting can be freely changed. You can Therefore, it is possible to effectively prevent or suppress the work with the back or waist bent and the difficulty of seeing the documents and screens on the top plate, and to maintain the correct posture. It is possible to continue healthy office work.

  Moreover, in this table T, since a common operating body 42 for switching the locked state of the pair of left and right gas springs 41 is arranged in the center of the tilt top plate 2 in the left-right direction, it is added to this operating body 42. It is possible to make the pair of wires w that transmit the operating force to each of the gas springs 41 have the same length. Therefore, it is possible to easily lead the wire w to the left and right gas springs 41 with a good appearance, and it is possible to reduce the number of types of parts and reasonably reduce the man-hours required for manufacturing and assembling.

  Further, in the present embodiment, since the operating body 42 for switching the locked state of the gas spring 41 is provided in the center of the tilt top plate 2 in the left-right direction, the user seated on the side of the use end 2b of the tilt top plate 2 is seated. When performing an operation to change the tilt position of the tilt top plate 2, if the right hand is used, the body is moved slightly to the left from the center, and if the left hand is used, the body is moved from the center. By slightly moving to the right, the operation body 42 can be accessed and the operation can be easily performed. Therefore, such a configuration facilitates the operation of tilting the top plate regardless of the dominant hand.

  Further, the left and right bases 1 are connected by the connecting beam 6, and the two wires w extending from the operating body 42 are guided by the connecting beam 6 and guided to the respective gas springs 41. 6 can be stored. Therefore, it becomes easy to handle the wire w with good appearance.

  In addition, since the two wires w are branched to the left and right in the connecting beam 6, it is possible to bring the two wires w close to each other in the region from the operation body 42 to the connecting beam 6. It is possible to particularly effectively suppress the disorder of the wire w.

  In addition, in the table T, the electric lifting mechanism 3 performs the operation of lifting and lowering the entire weight of the base 1, the connecting beam 6, the tilt top plate 2, the fixed shelf plate 5, the panel 8 and the like, and a large force is not required. Since the manual tilt mechanism 4 is used to adjust the tilt position of the tilt top plate 2, which needs to be changed relatively frequently according to the user's preference, tiredness, or changes in work content. It is possible to obtain the above-mentioned effects without complicating the mechanism or making the setting difficult. That is, in this table T, since only the tilt table 2 is moved up and down by electric force, the structure is simplified as compared with the case where the table lifting and tilting operations are performed by independent electric mechanisms. In addition, it is possible to eliminate the difficulty in operating a single article by a plurality of electric mechanisms. Specifically, when a single top plate is operated by a plurality of types of electric mechanisms, an interlock control circuit that controls the operation priority among the electric mechanisms and a safety circuit for emergency stop that integrates a plurality of electric mechanisms. It may be necessary to incorporate the above, but in the table T, such consideration is not necessary at all, and the implementation can be facilitated. In other words, since the electric lift mechanism 3 of the table T is electrically completely separated from the manual tilt mechanism 4, for example, it is the same as the electric lift mechanism used for a table that can only lift the top plate. It is also possible to use an electric lifting mechanism with a mechanism and control circuit.

  Further, since the tilt position can be changed by adjusting the force of pushing down the use end 2b side of the tilt top plate 2, it is possible to make a delicate adjustment according to preference. In particular, in the table T of this embodiment, since the operating body 42 can be operated while holding the use end 2b of the tilt top plate 2, it is easy to set the tilt top plate 2 at a desired tilt angle position. Further, since the gas spring 41 can be compressed by utilizing the weight of the user to store the repulsive force, it is possible to prevent the tilt operation from being heavily burdened.
