As a means to do so, the prior art Act Publication No. 56-25586
In the publication, the back panel is configured to be double layered, upper and lower, the upper panel is fitted into the lower panel so as to be movable up and down, and the lower panel has a substantially vertical guide wall and faces the guide wall and tapers downward. A vertically movable cylindrical piece member is provided between the two guide walls, and a vertically movable cylindrical piece member is urged downward by a spring, and a vertically long piece member fixed to the upper panel is provided between the vertical guide wall and the piece member. We are proposing a configuration with guide strips.

According to this prior art, when the upper panel is lowered, its guide strip is pressed against the vertical guide wall and lowered by the downward wedge action of the inclined guide wall in the lower panel and the downwardly biased piece member. On the other hand, when the top panel is pulled upward, the bridge member moves slightly upward to release the wedge action and smoothly pull up the top panel.

Furthermore, as a means of locking the upper panel at a desired height position, the frictional force between the inclined guide wall of the lower panel and the bridge member is utilized, but as these members wear out, the frictional force decreases. If the upper panel is lowered, there is a risk that the upper panel may slide down unexpectedly, and the function to stop the upper panel at a predetermined height may not be complete.
Furthermore, the downward movement of the upper panel does not stop until the wedge action between the upper panel and the lower panel is exerted, making it difficult to finely adjust the height position of the upper panel.

In order to solve this problem, the present invention provides a back panel along the back of the desk so that it can move up and down, and a drive shaft that is rotatably driven by the handle operation is supported on the underside of the desk top. The rear panel is configured to move up and down as the shaft rotates, and the drive shaft is fitted into a lock member that is non-rotatably mounted on the desk, and an engaging portion provided on the outer periphery of the drive shaft locks the lock member. The drive shaft or the lock member is configured to be slidable in the axial direction of the drive shaft so as to be engaged with and disengaged from the member, and the drive shaft or the lock member is biased by a spring in the engagement direction, and is driven by pressure from the handle. The shaft or the lock member is configured to slide in the direction in which the engagement between the two is released.

In this configuration, by interlocking and connecting the drive shaft and the rear panel via a connecting means such as a chain or wire, the rear panel can be raised and lowered as the drive shaft rotates. Since the engaging portion provided on the front panel and the non-rotatable locking member are spring-biased to engage each other, under normal conditions, the drive shaft is locked unrotatably and the back panel is stopped without being able to move up or down. On the other hand, when the handle is engaged with the drive shaft and the handle is pressed against the drive shaft or the lock member in the axial direction, the drive shaft or the lock member moves in the disengagement direction against the spring force. The drive shaft is unlocked and can rotate freely.

Therefore, by pressing the handle and rotating the handle while the drive shaft is unlocked, the rear panel can be raised and lowered.
When the pressure with the handle is stopped when the rear panel reaches the desired height position, the drive shaft or locking member slides in the locking direction by the spring force, the drive shaft is locked so that it cannot rotate, and the rear panel remains at that height. It will stop at that position.

In this way, the present invention allows the back panel to be moved up and down by operating the handle from the front or side of the desk.
You can raise and lower the back panel in a very natural posture without having to take any forced postures, and you can raise and lower the back panel and lock/unlock it with one hand by operating the handle, which is necessary for adjusting the height of the back panel. It has the effect of reducing labor.
