They are integrated by connecting the guide pieces (11a) with a connecting frame (16) that faces in the left-right direction.

Therefore, the guide (15) and the connecting frame (16)
Is integrated with and fixed to the desk (1) through the bracket (11) and the panel mounting bracket (13),
The panel (2) moves up and down as the panel rail (14) slides on the fixed guide (15).

As shown in FIG. 4, a positioning mechanism (17) is provided between the guide piece (11a) and the vertical rod (3) so that the panel (2) can be adjusted to a desired height. I have.

Next, the configuration of the positioning mechanism will be described.

As shown in FIGS. 6 and 7, the positioning mechanism
(17) is a pair of upper and lower guide shafts (1) projecting from the guide piece (11a).
8) (18), and a slide body (20) having a U-shaped cross section which is guided by a pair of upper and lower guide holes (19) (19) and is provided so as to be vertically movable,
A lock member (21) that is stacked on the slide body (20) and rotatably provided on the lower guide shaft (18), and a lock member (2
A spring (22) for urging the 1) to rotate clockwise, and a locking hole (not shown) formed by cutting out a corner of a vertical rod (3) having a U-shaped cross section shown in FIGS. 6, 7 and 9. 23) and the vertical rod (3) as shown in FIG.
An L-shaped lower protruding piece (24) projecting below the lower end (20a) of the slide body (20) so as to be in contact with the lower body (20), and a vertical rod shown in FIGS.
An intermediate portion of (3) is provided with an L-shaped upper protruding piece (25) projecting from the upper end (20b) of the slide body (20).

As shown in FIGS. 7 and 8, the lock member (2
1) includes a locking piece (21a) that engages with the locking hole (23) and a locking piece.
(21a) formed at right angles to the side surface (3a) of the vertical rod (3).
Abutment piece (21b) that comes into contact with the inner wall (20c) of the slide body (20)
And a contact surface (21c) that is in contact with. As shown in FIG. 7, a locking piece (21) is provided on a side wall (20d) of the slide body (20).
A notch (20e) into which the a) and the contact piece (21b) enter is formed.

Next, the operation of the above-described positioning mechanism will be described.

As shown in FIGS. 4 and 10, the panel (2)
The locking piece (21a) of the lock member (21) is held at a predetermined height by engaging with the locking hole (23). That is, the lock member (2
In 1), a clockwise rotation force is applied due to the load of the panel (2), but the contact piece (21b) is
(3) is in contact with the side surface (3a), and the contact surface (21c) is on the inner wall (2).
0c), the lock member (21) supports the panel (2) with its rotation restricted.

As shown in FIG. 11, when the panel (2) is raised to increase the height of the panel (2), the panel (2)
The vertical rod (3), which is the frame of the upper part, rises and the lower edge (2) of the locking hole (23)
3a) rotates the lock member (21) counterclockwise against the elastic force of the spring (22) to release the engagement between the lock hole (23) and the lock member (21). Since the clockwise urging force of the spring (22) is acting on the lock member (21), when the panel (2) is pulled up, the locking piece (21a) moves to the next lower locking hole (23). ). As a result, the panel (2) is fixed to one of the locking holes (23).
It can be raised by the pitch.

If the height is to be further increased, the panel
Pull up the (2) and insert the locking piece (2) into the lower locking hole (23).
1a) is engaged.

As described above, the positioning mechanism (17) engages and disengages the locking member (21) with the locking hole (23) to thereby control the panel.
A ratchet mechanism that allows the height of (2) to be adjusted stepwise. FIG. 12 shows the lowermost locking hole (23)
This is a state in which the locking pieces (21a) are locked to hold the panel at the highest height.

After setting the panel (2) to the highest height,
Alternatively, when lowering the panel (2) after setting it at the medium height, raise the panel (2) once to the top, lower it to the bottom, and then raise it again. Thereby, the panel (2) can be set to a desired height.

That is, as shown in FIG.
(2) is raised to the highest position, and the lower projecting piece (24) projecting from the lower part of the vertical rod (3) is brought into contact with the lower surface of the slide body (20), and the slide body ( 20) Push up.

Then, the lower edge of the notch (20e) of the slide body (20) rotates the lock member (21) counterclockwise against the urging force of the spring (22), thereby causing the lock member (21) to rotate. Release from the locking hole (23). The lock member (21) is pressed against the side wall (20d) of the slide body (20) by the spring (22) and cannot be engaged with the locking hole (23).

In this state, as shown in FIG.
Lower (2). When the panel (2) is lowered, the lock member (21) is moved by the spring (22) to the side wall (2) of the slide body (20).
0d) is pressed to hold the slide body (20) at a higher position on the guide piece (11a).

As shown in FIG. 15, when the panel (2) is lowered to the lowest position, the upper protruding piece (25) protruding from the intermediate portion of the vertical rod (3) pushes down the slide body (20). Then, the locking piece (21a) of the lock member (21) protrudes from the notch (20e) of the slide body (20).

When the panel (2) is pulled up again and the locking member (21) is engaged with the locking hole (23) higher than the previous locking hole (23), the panel (2) can be moved to a desired position. It can be held at a low position.

The above-described panel (2) is provided with a constant load spring which assists the force for supporting the panel (2) when adjusting the height. As shown in FIGS. 4 and 16, the constant load spring (26) is provided with a connecting frame (16) and a lower horizontal rod (2) so that the panel (2) can be moved up and down with a small force. 4)
And is provided between them.

A constant load spring (26) is housed in the panel (2), and is provided on a bracket (27) on the horizontal rod (4) via a shaft (28). An elastic strip steel plate (30) wound around (29) and having an unwinding end (30a) attached to the connecting frame (16). The rear panel plate (6) has a projection (6b) for accommodating the drum (29).

The constant load spring (26) is such that an elastic strip steel plate (30) is wound around a drum (29). For this reason, when the elastic steel plate (30) is pulled out, a tension is generated against it. Moreover, this tension is substantially constant irrespective of the length of the drawn out elastic steel plate (30).

Therefore, when the panel (2) moves up and down, the drum
(29) also moves up and down integrally with the panel (2). However, since the connecting frame (16) is fixed to the desk (1) via the guide piece (11a), the bracket (27) and the panel mounting bracket (13), the fixed connecting frame (16) The unwinding end (30a) of the elastic strip steel plate (30) attached to the arm does not move up and down.

As described above, the constant load spring (26)
When lowering (2), the elastic strip steel plate (30)
When the panel (2) is pulled out from 9) and serves as a force to lift the panel (2) to support the panel (2) and raise the panel (2),
The elastic band steel plate (30) is wound around the drum (29) and the panel
Helps raise panel (2) by taking part of the power to raise (2). That is, the constant load spring (26)
(2) The weight balance can be obtained.

In addition, since the tension of the constant load spring (26) is substantially constant irrespective of the length of the elastic strip steel plate (30) drawn out, the tension is substantially constant irrespective of the height of the panel (2). As a result, the height of the panel (2) is assisted, and the height of the panel (2) can be easily adjusted by a single person even if the person is a weak person.

[0036]

According to the first aspect of the present invention, since the panel is provided with the positioning mechanism, the height of the panel can be easily adjusted by one person. Moreover, since the positioning mechanism is provided between the guide body and the vertical rod, the structure can be simplified.

Since the positioning mechanism is of a ratchet type comprising a lock member and a locking hole, the panel can be easily held at a desired height.

According to the third aspect of the present invention, when the release holding member is provided, even if the positioning mechanism is of a ratchet type, the panel can be brought to a desired height again after the panel is pulled up to the uppermost position.
