As a result, the tilting top plate 2 pivotally supported on the base 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 5 and the panel 8 are attached to the base 1 and the wiring duct 7 is attached to the connecting beam 6, the heights of the fixed shelf 5, the panel 8 and the wiring duct 7 are 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 and the tilt top plate 2 is lowered to the sitting position D, and FIGS. is raised to the standing position U.

Further, by operating an operation body 42 provided at the center of the tilt top plate 2 in the left-right direction, the left and right gas springs 41 can be unlocked, 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 operating lever 422 of the operating body 42 is rotated from the locked position indicated by the solid line to the unlocked position indicated by the imaginary line, the operating 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 pulled forward and rotated from the locked position indicated by the solid line in FIG. rotates from the non-operating end pressing position indicated by the solid line to the operating end pressing position indicated by the imaginary line, and the gas spring 41 is brought into the unlocked state. In this state, as shown in FIG. 23, the operation lever 422 can be held at the unlocked position while the use end 2b of the tilt top plate 2 is gripped from above and below. Therefore, by pushing down the use end 2b of the tilt top plate 2 in this holding state, the tilt top plate 2 can be tilted from the horizontal posture h toward the tilt posture s. This tilting operation is performed while resisting 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 pushing down the tilt top plate 2 is relaxed in this holding state, 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 inclination 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. FIG. Then, when the tilt top plate 2 reaches a desired tilting position, when the finger is released from the operation lever 422, the operation lever 422 self-returns to the original locking position, the gas spring 41 is locked, and the tilt top plate 2 tilt operation is prohibited. 5, 6, 9 and 10 show the state in which the tilt top plate 2 is tilted to the extreme tilt position s and locked.

<Action and effect of the present embodiment>
With such a configuration, the tilting top plate 2 can be used by freely changing the height position and the tilting position. In addition to being able to freely select the mode of use at the standing position U, it is also possible to arbitrarily change the inclination angle of the tilt top plate 2 at each height position. That is, according to this table T, the height and inclination of the tilt top plate 2 can be freely set according to the user's physical characteristics, work content, etc., and the setting can be freely changed. can be done. Therefore, it is possible to effectively prevent or suppress the situation where the user is forced to work with the back or waist bent, or the document or screen on the tabletop surface becomes difficult to see. It is possible to continue healthy office work and the like.

Moreover, in this table T, the electric lifting mechanism 3 supports the total weight of the base 1, the connecting beam 6, the tilting top plate 2, the fixed shelf plate 5, the panel 8, etc., and lifts it up, so that a large force is not required. However, 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, degree of fatigue, or change in work content. The effects described above can be obtained without complicating the mechanism or making the setting difficult. That is, in this table T, only the lifting and lowering of the tilting top plate 2 is performed by electric power, so that the structure is simplified compared to a table in which the lifting and tilting operations of the top plate are performed by independent electric mechanisms. In addition, the difficulty of actuating a single article with multiple motorized mechanisms can be eliminated. Specifically, when a single tabletop is operated by multiple types of electric mechanisms, an interlock control circuit that governs the order of operation among electric mechanisms and a safety circuit for emergency stop that integrates multiple electric mechanisms. etc. may be required to be incorporated, but in the present table T, such consideration is not required at all, and the implementation can be facilitated. In other words, since the electric lifting mechanism 3 of the table T is completely electrically separated from the manual tilting mechanism 4, it is the same as the electric lifting mechanism used for a table that can only raise and lower the top board. It is also possible to use a motorized lifting mechanism with its own mechanism and control circuitry.

In addition, since the tilt position can be changed by adjusting the force for pushing down the use end 2b side of the tilt top plate 2, it is possible to finely adjust according to one's preference. Particularly, with the table T of this embodiment, it is possible to operate the operation body 42 while holding the use end 2b of the tilt top plate 2, so that the tilt top plate 2 can be easily set at a desired tilt angle position. Furthermore, since the gas spring 41 can be compressed using the user's weight to accumulate a repulsive force, it is possible to prevent a large burden from being applied to the tilting operation.

<Other embodiments>
The present invention is not limited to the embodiments described above, and various modifications are possible without departing from the scope of the invention.

For example, the inventions of claims 1 and 2 include those using a single base or three or more bases or legs, and the structure of the legs as a whole is also expandable. Not limited.

Also, the electric lifting mechanism may be of any type as long as it lifts and lowers the base using electric power. Various things can be adopted. However, if the structure is such that the base is supported by the legs and the base is moved up and down by the expansion and contraction of the legs using electric power, the base is supported by the legs regardless of the height position of the base and the tilt top plate. And the tilt top plate can be stably supported.

Further, the manual tilt mechanism may be of any type as long as the lock state of the gas spring can be changed by manipulating the operation body. For example, the gas spring does not have to be provided outside the center of the leg, and the arrangement position of the operation body is not limited to the center in the left-right direction near the use end on the lower surface of the tilt top plate. However, for example, as in the above-described embodiment, the repulsive force is accumulated in the gas spring by manually tilting the tilt top plate in the opposite direction with the gas spring unlocked. For example, as described above, the user's weight is used to compress the gas spring to accumulate the repulsive force, thereby realizing a configuration capable of preventing a large burden from being applied to the tilting operation. Also, if the operating body is provided near the use end on the lower surface of the tilt top plate, the operating body (operating lever) is held at the unlocked position while gripping the use end of the tilt top plate from above and below. Therefore, by pushing down the use end portion of the tilting top plate in this holding state, the tilting top plate can be tilted from the horizontal posture toward the inclined posture. Furthermore, if the operation body is arranged in the center of the tilting top plate in the left-right direction, the distance from the left and right gas springs to the operation body can be made equal. It is possible to easily realize a configuration that evenly transmits the operating force.

Depending on the use of the table, it is not always necessary to provide the fixed shelf board as in the above-described embodiment, and it is of course possible to omit the fixed shelf board.

In addition, various modifications may be made without departing from the gist of the present invention.
