Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a partition unit.

[Prior art and problems to be solved by the invention] Conventionally, a partition unit consists of a partition wall and a pile or board inside the partition. It was necessary to install a drafting table. Therefore, the drafting compartment and other office compartments have completely different configurations, and it has been difficult in the past to make them serve both purposes. In addition, the above drafting table has supporting legs for the floor-mounted base,
There was also the problem that the legs got in the way when drawing. Furthermore, in a small office or the like, separate space for drafting and other office space are required, which increases the overall required floor space.

[Means to solve the problem]

In order to solve these problems, the present invention is provided with a partition wall structure having at least left and right partition side walls as a partition unit, and a drafting base to which a drawing board and a drafting instrument are attached can be raised and lowered to the partition wall structure. The partition wall structure is provided with an elastic means inside the walls or pillars, and the elastic means and the drawing base are interlocked and connected via a pulley mechanism, and the drawing board and the drawing board are connected to each other through a pulley mechanism. The weight of the instrument and the drafting base is reduced by the above-mentioned elastic means, and an electric motor is attached to the pulley mechanism in an interlocking manner.

Further, the pulley mechanism is provided with a synchronous shaft for synchronizing the raising and lowering operations of the left and right edges of the drafting base, and is connected to the electric motor via a drive transmission mechanism that transmits rotational driving force to the synchronous shaft. Interlocked with the shaft.

Further, the resilient means is configured by connecting two or more gas springs in series.

The pulley mechanism was formed so that the ratio of the vertical stroke of the firing means to the vertical stroke of the drafting base was (1:2'') (where n is a natural number).

[For production]

The drafting base to which the drafting board and drafting equipment are attached is supported and attached to the partition wall structure by a pulley mechanism (without using the supporting legs of a conventional drafting table). The firing means reduces (balances) the weight of the drawing board, drawing equipment, and drawing base, and the electric motor can be sufficiently raised and lowered even if it is small and has low horsepower. Along with this,
The electric motor and its drive transmission mechanism can be easily built into the wall or ceiling of the partition structure (so that they are not visible from the outside).

Since the supporting legs of the conventional drafting table are eliminated, the space below can be freely used for various purposes, and it does not get in the way of the worker's legs.

In addition, the synchronous shaft synchronizes the left and right lifting strokes, allowing the drafting board to be raised and lowered while always keeping it horizontal. By interlocking and connecting an electric motor to this synchronous shaft, it is easy to maintain balance between the left and right layers.

In addition, by using an elastic means in which two or more gas springs are connected in series, it can be easily stored inside a partition side wall, etc., and by using a gas spring with a standard stroke, a sufficient drafting base can be obtained. A vertical stroke can be obtained. Furthermore, by setting the ratio of the vertical stroke of the resilient means to the vertical stroke of the drafting base to be (1:2'') (where n is a natural number), the necessary stroke of the resilient means can be reduced to 1/2R.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

In FIGS. 1 to 6, 1 is a drafting base, and 2 is a partition wall structure comprising left and right partition side walls 3.3 and a rear partition rear wall 4. A drawing board 5 is attached to the drawing board 5, and a drawing instrument 6 (shown in FIGS. 4 and 5) is attached to the drawing board 5.

As shown by the imaginary line in FIG. 7, the rear wall 4 can be omitted in the present invention. That is, it is sufficient to have at least left and right side walls 3.3. However, a ceiling part 7 and a connecting rod (girder) near the rear wall are required to connect the left and right side walls 3.3.

The drafting base l includes a main body part 8 which is always horizontal, a drawing board mounting member 10 pivotably supported on a shaft 9 near the front edge of the main body part 8, and a tilting drive means A (a ninth (see Figure 1 and Figure 10).

Therefore, this drafting base 1 is provided in the internal cavity 11 of the partition wall structure 2 so as to be movable up and down, and the drafting base 1 is placed in the upper storage state U near the ceiling 7 of the internal cavity 11 (in the third (see Figures 1 and 5) and drafting usage state B (see Figures 1 and 4,
or (see Fig. 2)). In Fig. 1, the illustration is based on the two sides of the drawing board 5 in a horizontal state. ing.

As shown in FIG. 9, the drawing board 5 is tilted back and forth within a predetermined angle range θ by the tilt drive means A.

For example, the forward tilt angle θ is set at a maximum of about 75° from the horizontal state. In FIG. 1, the drafting base 1 (therefore, the drafting board 5) is lowered to the lowest limit and is used for drafting work within an angular range θ from the solid line to the imaginary line.

As is clear from FIGS. 1, 3, and 8, the front edge 5a of the drawing board 5 and the front edge 1a of the drafting base 1 are located further back than the front edges 3a3a of the partition side walls 3, 3, respectively. The relative dimensions and relative positions of the drawing board 5 and the side walls 3, 3 are set so that the drawing board 5 and the side walls 3, 3 are positioned.

Of course, the rear edge 5b of the drawing board 5 and the rear edge 1b of the drafting base 1 are set to be located forward of the rear edges 3b, 3b of the side walls 3.3, respectively.

Note that in the case where the side wall 3 has a column member, the front edge 3a and the rear edge 3b are defined to include this column member.

Next, reference numeral 12 is a first lighting light provided on the ceiling 7 of the partition wall structure 2, and on the ward side, three fluorescent lights are installed on the ceiling 7.
It is attached along the leading edge of the In addition, a second illumination light 13 that illuminates the lower part of the drafting board 1 is installed (as shown in Figures 1 to 3).
It is provided on the drafting base 1.

On the ward side, a pair of two fluorescent light groups are attached on the left and right to form the second illumination light 13.

Therefore, in FIGS. 6 and 7, the partition wall structure 2
The above-mentioned drafting base l provided therein can be suspended and displayed via a pulley mechanism 14. Here, the pulley mechanism 14 includes a plurality of rotors 18, 19, 20° 21, 22, 23
, a flexible suspension member 15.15 that engages with the rotor 21, 20, 19, 23, and a synchronous shaft 16 that connects the opposing rotor 19.19.

That is, the rotor 18.18 is the leading edge 3a of the side walls 3,3.

3a, the rotors 19.22 are pivoted on the trailing edges 3b, 3b in close proximity to each other, and both rotors 19.22
rotates as one. Further, the rotor 20 is disposed above the rotor 19 in front, and the rotor 21 is disposed above the rotor 19 in the rear.

The rotor 20 applies tension to another flexible suspension member 24 (described later).

25 is two or more gas springs 26°26
are connected in series coaxially, and the pair of left and right resilient means 25.25 are connected to the rotor 1.
9.19, and the thickness of the side wall 3.3 is increased as shown by the imaginary line E in FIG. It is desirable that the resilient means 25 be contained inside the column defined as being included in the section and not exposed to the outside. This explosive means 25
A rotor 23 as a movable pulley is pivotally attached to the lower end of the gas spring 26, 26 as a movable pulley.

The flexible hanging member 24.24 has one end 24a, 24a
At the front ends of the left and right front extension parts 27 and 27 of the drafting base 1,
It is fixed via the connecting piece 28.28. In addition, each of the flexible hanging members 24, 24 reaches the rotor 23 via the rotor 18, 22, where it is reversed 3606, and the other end 24.
b is fixed to a part of the side wall 3. Further, each of the other flexible hanging members 15.15 has one end 15a fixed to the rear edge of the drafting base 1, passes through the rotor 21.20.19, and reaches the rotor 23 as a movable pulley. Here, 360a is reversed and the other end 15b is fixed to a part of the side wall 3.

The rotors 18 to 23 are composed of chain wheels, pulleys, etc., and the flexible hanging members 15, 24 are composed of belt-shaped bodies having uneven meshing parts, such as chains or toothed belts.

As a result, the symmetrical rotors 18 to 23, the flexible suspension members 15 and 24, etc., which are disposed within the left and right side walls 3.3, are connected to the synchronous shaft 16 which is disposed within the rear edge of the ceiling portion 7. , the drafting base 1 can be raised and lowered while maintaining the horizontal position without tilting to the left or right. Then, the total dead weight of the drawing board 5, the drawing instrument 6, and the drawing base l is reduced by the elastic means 25.

An electric motor 29 is interlocked and connected to the synchronous shaft 16, which forms part of the pulley mechanism 14, via a drive transmission mechanism 33.

On the district side, a rotating drive wheel 30 such as a chain wheel or a pulley is fixed to a part of the synchronous shirt 6, and a chain, toothed belt, etc. A drive transmission mechanism 33 for transmitting drive rotational force to the synchronous shaft 16 was constructed by suspending an endless flexible member 32 .

Therefore, as is clear from FIG. 6, the ratio of the vertical stroke S' of the springing means 25 to the vertical stroke S of the drafting base 1 is 1:2. Of course, if the number of movable pulleys and fixed pulleys (corresponding rotors) of the pulley mechanism 14 is increased, (S':S
) can be set to (1:4), (1:8), etc.

In other words, it is set as S':S=1:2'' (where n is a natural number).

Next, in FIGS. 7 and 11, 34 is a detector such as an encoder that detects the vertical position of the drafting base 1 as the rotational position (number) of the synchronous shaft 16. An illumination control device 35 is provided which turns on the first illumination light 12 and the second illumination light 13 according to the signal p from the detector 34. In FIG. 11, the signal p is once manually input to the lighting control device 35 via the comparison means 36.

As shown in FIG. 1, when the vertical position of the drafting base 11 is indicated by the vertical position of the upper surface of the (horizontal) drafting board 5 attached to it, the first illumination light 12 is The second illumination light 13 is turned on only in the range of the first stroke F upwards from the lower limit of the height, and the second illumination light 13 is turned on only in the range of the second stroke G downward from the upper limit T of the total raising stroke S. Set the lights so that F>(1/2)・S G>(1/2)・S, and be sure to set the first and second illumination lights at 12°13
@ control so that both have an overlapping area W that lights up.

Therefore, in FIG.
7, and storage means 3 for storing future setting input values.
8, inputs the signal a from the storage means 38 to the above-mentioned comparison means 36, compares it with the signal p from the detector 34, and then sends the signal to the lighting control device 35. From here, signals c and d are sent to the first and second illumination lights 12.1, respectively.
3, and as shown in the explanatory graph in Figure 1, turn on the light.
Control smoke elimination.

In other words, when the drafting base 1 is in the upper stowed state U shown in FIG.
Only 3 lights up. Furthermore, when the drafting base 1 is in the intermediate height drafting use state B shown in FIG. 2 or the lower drafting use state B shown in FIG. The illumination light 12 is turned on.

In addition, in Figure 1, drafting work is generally performed while sitting on a chair (not shown), and in Figure 2, drafting work is generally performed while standing (or a tall person is sitting on a chair) as shown in the imaginary line. (Drawing work) and Figure 3 (or Figure 5)
Now, the desk (table) 3 installed at the bottom of the internal empty space 11.
9 to do desk work (general office work),
Because it is used, each lighting effect is efficient and effective.

Furthermore, the above-mentioned first and second illumination lights 12.13 are both turned on when switching up and down between FIG. 2 and FIG.
This is in the transition area (overlapping area W) in the figure. By having such an overlapping area W, even if the entire room is dark,
Brightness can always be maintained inside the partition unit of the present invention.

In the rotation shown in FIGS. 1 to 3, the synchronized shirt eye 6, the electric motor 29, the drive transmission mechanism 33, etc. are housed in a hollow box 40 made of sheet metal and having a substantially rectangular cross section. This hollow box 40 corresponds to a crossbeam forming a part of the ceiling section 7. Furthermore, the partition side wall 3 is composed of pillars 4142 made of metal shapes with hollow chambers at the front edge 3a and rear edge 3b, and includes the resilient means 25, the rotor 23, the flexible suspension member 15. 24, etc. are housed within the pillars 41 and 42 and are not exposed to the outside, improving safety and aesthetics. 43... is this pillar material 4
1.42 is a longitudinal slit opening on the inner surface of the slit 43, and the connecting piece 2 shown in FIGS. 7 and 4 moves up and down along this slit 43.

In addition, in the upper stowed state U shown in FIGS. 3 and 5, the drawing board 5 is automatically controlled to be always in a horizontal state, and is raised as close to the ceiling 7 as possible to cover the space below. It is designed to be spacious. However, Figures 1 to 2
In the current drafting use case jliB, the drafting board 5 can be tilted to a desired angle by the tilting drive means A.

In addition, in the case of turning the table 39 shown in FIGS. 1 to 5, the desk 39 is fixed to the partition wall structure 2, and in addition to this, an arrangement part such as a drawer may be attached. On the other hand, it is preferable that such a desk 39 or the like is not provided in the lower part of the internal space 11, and that a separate desk, organizing box, OA equipment, etc. can be installed freely (not shown).

In addition, an operation panel 44 equipped with various switches etc. in FIG.
is provided in a part of the drafting base 1, as shown in FIG.
In addition, some of the switches are provided within the operation panel 45 on the lower inner surface of the side wall 3 in FIGS. 1 to 3.

As shown in FIG. 6, two or more gas springs 26.26 are connected in series, and the total stroke of the gas springs 26.26 is (1/21') using the pulley mechanism 14 (where n is a natural number). Therefore, by using a short gas spring 26 that is easily available, a sufficiently large lifting stroke S can be achieved.
(See Figures 1, 2, and 4).

In FIGS. 6 and 7, it has already been mentioned that the synchronous shaft 16 is attached to synchronize the left and right vertical movement. It is reasonable to drive it in such a way that synchronization between the left and right sides is not impaired and an average force is applied to the left and right flexible hanging members 15, 24... Further, it has the advantage that it can be easily stored in the ceiling part 7, and parts of the side walls 3 do not protrude.

' is the maximum inclination angle θ.

Conversely, if the electric motor 48 is reversed, it returns to the horizontal state. Note that, except for the upper half of the push-up arm 52, the tilting drive means A is housed in a flat box-shaped main body 8 made of hollow sheet metal.

In FIG. 11, the shaft 9 is fixed to a clevis 54 and tilts together with the drawing board 5. A rotor 55 is fixed to this shaft 9, and a rotation angle detector 56 such as an encoder is connected to the shaft 9.

It is possible to set the user's preferred drafting posture in advance according to the user's preferences and body size. These will eventually be stored in the storage means 38.

Further, command signals from various operation command switches 64, 65, 66, 67 are connected to storage means 38 for manual input, and signal a from storage means 38 is sent to comparison means 36. Feedback signals p and e from a detector 34.56 such as a pulse oscillator such as an encoder are input to this comparison means 36. Then, the comparison means 36
