Description

Description: TECHNICAL FIELD The present invention relates to a table used as an OA table or the like on which an OA device such as a word processor and a personal computer is mounted.

[Conventional technology]

Conventionally, like an OA table, it has a front top plate and a rear top plate,
Equipment on both tops (eg keyboard on front top,
A display device) is placed on each rear top plate, and a left and right side support structure that supports the top plate load on both left and right sides as a table top support structure for a user who sits in a chair and operates this equipment Is common.

[Problems to be Solved by the Invention]

However, according to this conventional structure, since the user puts both legs between the left and right columns to face the table, the columns limit the position of the legs and the movement and opening of the legs.

In particular, in the case of an OA table, the width is smaller than that of a general desk, and the spacing between columns is therefore small, so that the legs are fixed between the columns. For this reason, the lower half of the body becomes extremely cramped, and the movement of the upper body is also restrained accordingly, which tends to make the posture rigid, which adversely affects the operation of the keyboard and the like and causes severe fatigue. It was

On the other hand, as a top plate support structure that can eliminate this drawback, as shown in No. 61-33127, the rear top plate is attached to the upper end of one column, and the bracket is attached to this column forward. A single column structure in which a front top plate is attached to the bracket is known.

However, according to this configuration, since the front top plate is deviated forward with respect to the support column for supporting the load, the weight of the devices placed on the front top plate causes the forward tilting moment to act on the entire mounting table. However, stability becomes poor.

Therefore, in order to increase the supporting moment against the overturning moment, it is necessary to increase the forward protrusion amount of the leg body that supports the support column.

As a result, the legs protruding largely forward penetrate deeply between the legs of the user, so that the position and movement of the legs are restricted.

Moreover, since the legs are radially attached to the columns, the positions of the legs are increasingly restricted by the legs.

Therefore, the present invention provides a table that allows keyboard operation and the like in a comfortable and comfortable posture without any restrictions on the position, movement, or opening of the legs.

[Means for Solving the Problems]

According to a first aspect of the present invention, in a table provided with a front top plate and a rear top plate, a front pillar to which the front top plate is attached, a rear pillar to which the rear top plate is attached, and the front pillar and the rear pillar are integrally formed in a state in which a front and rear space is provided therebetween. A pillar having a front-rear two-pillar structure is configured with a connecting member that connects, and at the lower part of this pillar, one front leg extending in front of the front pillar and two rear portions extending on both left and right rear sides of the rear pillar. It is made by attaching the legs.

According to a second aspect of the present invention, in a table including a front top plate and a rear top plate, a front pillar to which the front top plate is attached and a rear pillar to which the rear top plate is attached are provided, and one of the front pillar and the rear pillar is provided. The lower part of the column is bent and the bent ends are connected to the other to form a column with a front and rear two-pillar structure. At the bottom of this column, one front leg extending forward of the front column and a rear column are formed. And two rear legs that extend to the left and right sides of the rear.

According to the invention of claim 3 in the configuration of claim 1 or 2,
The front leg is attached to the lower surface of the portion of the support pillar that integrally connects the front pillar and the rear pillar, facing forward.

According to a fourth aspect of the present invention, in the structure according to any one of the first to third aspects, a notch is provided in a lower end surface of the column, and the leg body is attached to the lower end of the column while being engaged with the notch.

The invention of claim 5 is the configuration according to any one of claims 1 to 4, wherein the front protrusion amount l ₁ of the front leg body from the center of the front column and the rear protrusion amount l ₂ of the rear leg body from the center of the rear column. Relationship with l ₁ <l ₂
Is set to.

[Action]

According to the above configuration, the user places both legs on the left and right sides of the front column and front leg of the column, and is in a posture toward the table. Disappears.

In addition, since the load-supporting shaft is distributed to the front and back by the front and rear columns, the stability of the entire table is better and the load-bearing axis is better than that of the single-column structure shown in Japanese Utility Model Publication No. 61-33127. The performance is remarkably high.

This makes it possible to reduce the amount of forward protrusion of the front leg, and in combination with the fact that there is only one leg,
There is no risk that the front legs will hinder the position or movement of the legs.

That is, there is nothing that limits the position, movement, or opening of the legs. Therefore, the keyboard or the like can be operated in a comfortable and comfortable posture.

Moreover, as a general load distribution of this kind of table,
Since the front load is smaller than the rear load, one front leg can sufficiently support the front load.

In this case, since the front pillar and the rear pillar are formed as separate members, and these are connected by the connecting member to form the support pillar, it is relatively troublesome as compared with the case where the U-shaped support pillar is composed of, for example, one tubular body. Bending (bendering) is not required, resulting in high productivity.

Further, by forming the front pillar and the rear pillar as separate members, it is possible to make the diameters of these pillars different from each other in accordance with the loads applied to them and to use different materials for both pillars. In particular, if square pipes are used for both columns, curved surface processing of the end surface of the leg, which is required when using a round pipe, is not required, so that the leg can be easily processed.

Furthermore, as a means for attaching the leg to the column, the method according to claim 3
Alternatively, by adopting the configuration of 4, it is possible to obtain the same effect as described above.

Further, in the case of an OA table or the like, considering that the front load is generally smaller than the rear load, the relationship between the front protrusion amount l ₁ of the front leg body and the rear protrusion amount l ₂ of the rear leg body is set to l ₁ <l ₂ By setting to 1, the leg structure becomes compact, and the front leg is not obstructed more and more, and it becomes easier to use.

〔Example〕

 An embodiment of the present invention will be described with reference to the drawings.

First Embodiment (see FIGS. 1 to 4) In this embodiment, the OA table is used as an example of application.

A is a pillar, A ₁ is a front pillar that constitutes this pillar A, and A ₂ is a rear pillar.

The front pillar A ₁ and the rear pillar A ₂ are provided with lower fixed pipes (hereinafter, referred to as front pipe and rear pipe) 1 and 2 each made of a round pipe material, and gas springs S ₁ and S with a lock mechanism known as a lifting mechanism. _It is configured to be able to expand and contract continuously (height adjustment) by attaching ₂ to the upper edge of the front gas spring S _{1 and} the front top panel U ₁ on which the keyboard B is placed, and the upper edge of the rear gas spring S ₂ to the CR
Rear top plates U _{2 on} which the display devices C such as T are mounted are attached.

A connecting pipe 3 made of a round pipe material is attached between the lower portions of the front pipe 1 and the rear pipe 2 by welding or the like.
The pillar A is formed by integrally connecting A ₁ and A ₂ in a parallel state with a front and rear space.

The gas springs S ₁ and S ₂ have their rod ends fixed to the lower portions of the front pipe 1 and the rear pipe 2, and are attached to both pipes 1 and 2 so that the cylinder moves up and down during expansion and contraction operation. 2 to 4, 4 and 4 are operating levers of the gas springs S ₁ and S ₂ .

The front top plate U ₁ and the rear top plate U ₂ respectively include a Morse taper shaft 5 on the gas spring side and a Morse taper on the top plate side on which the Morse taper shaft 5 is fitted, on the upper ends of the cylinders of the gas springs S ₁ and S _2. It is attached via the pipe 6, and can be set at arbitrary height positions by adjusting the expansion and contraction of the gas springs S ₁ and S ₂ .

A valve (not shown) that controls pressurization (extension) and pressure release (reduction) of the gas springs S ₁ and S ₂ is provided at the upper end of the cylinder. The operation levers 4, 4 for operating the valves are arranged such that the lever ends thereof are located below and near the widthwise ends of the top plates U ₁ , U ₂ so that the upper end portions of the cylinders of the gas springs S ₁ , S ₂ are positioned. It is installed sideways along the bottom of the top plate.

In this way, when lowering the heights of the top plates U ₁ and U ₂ by holding them in the width direction, the operation lever 4 can be simultaneously grasped and pulled up (pressure release operation). . Therefore, even one person can easily perform the operation of lowering the top plate.

On the other hand, on the front pillar A ₁ of the pillar A, _one front leg body (hereinafter, simply referred to as front leg) 7 extending forward on the lower front surface of the front tube 1 is provided.
The rear pillar A ₂ is provided with a pair of rear leg bodies 8 (hereinafter, simply referred to as rear legs) 8 extending to the rear left and right sides on the lower left and right sides of the rear tube 2, and these three legs 7, 8, 8 Is configured to support the load at three points.

Each of these legs 7, 8 and 8 is formed of a round pipe material, and one end thereof is welded and fixed to the front pipe 1 and the rear pipe 2.

The length of each leg 7, 8 and 8 is such that each leg end does not crawl out of the top plates U ₁ and U _{2 in} plan view, or is very small even if it crawls out. Is set to. In this way, consideration is given so that the front leg 7 does not interfere with the use and the rear legs 8 and 8 do not interfere with the installation of the table on the wall. Denoted at 9 are casters for moving the table, which are provided at the tips of the legs 7, 8, 8.

In this OA table, the front pillar A ₁ and the rear pillar as described above
A ₂ and A ₂ are connected to each other with a space left and right to form a strut A, and this strut A is configured to be supported at three points by one front leg 7 and two rear legs 8 and 8. Both the column A and the front leg 7, which cause a problem of interference with both legs of the person, are located at the center of the table when viewed from the front. That is, the user puts his / her both legs on the left and right sides of the front leg 7 and the pillar A, and goes to the table.

Therefore, the position of both legs, the movement and opening of both legs are
And because it is not limited by the front legs 7,
The keyboard B can be operated in a comfortable and comfortable posture according to the user's physique and taste.

Moreover, as for the load distribution, the front side supporting the keyboard B has a much smaller load than the rear side supporting the heavy display device C, so that the one front leg 7 can sufficiently support the load. .

Second Embodiment (see FIG. 5) Only the differences from the first embodiment will be described.

In the case of the first embodiment, since the front leg 7 is welded to the lower front surface of the front pipe 1, it is necessary to perform a troublesome curved surface processing on the leg end surface as a common case when welding the pipe materials to each other.

Therefore, in the second embodiment, notches 10 and 11 are provided on the lower end surfaces of the front pipe 1 and the rear pipe 2, and the engaging portions are welded and coupled with each leg end engaged with the notches 10 and 11. I am taking means. This eliminates the need for curved surface processing of the leg end faces, thus simplifying the processing of the legs 7,8,8.

The notches 10 of the front pipe 1 are provided on both front and rear sides of the lower end face of the front pipe, and the notches 11 of the rear pipe 2 are provided on both left and right sides of the lower end face of the rear pipe.

Further, in this case, the notches 10 and 11 may be semi-circular as shown in the drawing, and the upper half in the radial direction of the leg ends may be welded in a semi-submerged state in which the notches 10 and 11 are engaged, The notches 10 and 11 may be extended upward and the leg ends may be welded in a completely submerged state.

Third and Fourth Embodiments (Refer to FIG. 6) As the pillar structure, in each of the above-mentioned embodiments, the front pipe 1 and the rear pipe 2 are connected to each other by the connecting pipes 3 at their lower portions, but in the fourth embodiment, both are connected. The pipes 1 and 2 are connected to each other by a connecting pipe 3 at substantially central portions thereof, so that the pillar A is formed in an H shape when viewed from the side.

On the other hand, in the fourth embodiment, as shown by the phantom line in FIG. 6, both pipes 1 and 2 are connected at their lower ends. Further, when the strut structure of the fourth embodiment is adopted, the front leg 7 is welded and fixed to the lower surface of the connecting pipe 3. In this way, connect the front leg end to the connecting pipe 3
The front leg 7 need not be machined or is simple because it can be welded directly to the lower surface of the front end or the peripheral wall of the same end can be flatly crushed and welded along the lower surface of the connecting portion.

Fifth Embodiment (Refer to FIG. 7) Similarly, in the above-mentioned respective embodiments, the front pillar A ₁ and the rear pillar are used as the pillar structure.
While the pillar A is constituted by A ₂ and the connecting pipe 3, in the fifth embodiment, the front pipe 1 of the front pillar A ₁ is bent into an L-shape to form the connecting portion 1a at the lower portion. The front end of 1a is connected to the rear tube 2 to form a column A.

Other Examples (a) The front pipe 1 and the rear pipe 2 have the same diameter in principle, but in the case of the OA table, the front load is generally smaller than the rear load, so the front pipe 1 is larger than the rear pipe 2. May have a smaller diameter.

To put it the other way around, by adopting the strut structure of each of the above-described embodiments in which the front pipe 1 and the rear pipe 2 which are separate members are connected to each other to form the strut A, for example, one pipe material is bent into a U-shape to be formed in front. As in the case where the pipe and the rear pipe are integrally formed, there is no restriction that the diameters of the pipes are uniformly specified, and it is possible to use the one having the optimum diameter according to the load applied to each. Of.

(B) For the same reason, as the material of the front pipe 1, the rear pipe 2, and the connecting pipe 3, it is not always necessary to unify them with the round pipe material as in the above embodiment, and all or some of them may be used. A square pipe or a pipe material having an oval cross section can be used. If square pipes are used for the front pipe 1 or the rear pipe 2 or both of them, the welding of the connecting pipe 3 to them can be simplified.

(C) In the above embodiment, gas springs S ₁ and S ₂ are attached to the front pipe 1 and the rear pipe 2 to form a front column A ₁ and a rear column A ₂ which are expandable and contractible, and the top plate height is adjusted by this. However, the height adjustment mechanism is omitted, and the front tube 1 and the rear tube 2 are
Alternatively, the top plates U ₁ and U ₂ may be directly attached to the upper ends of these as the front pillar A ₁ and the rear pillar A ₂ . In this case, the lengths of both tubes 1 and 2 (the heights of the top plates U ₁ and U ₂ ) may be different or the same.

(D) As the material of each leg 7, 8, 8, instead of the pipe material used in the above embodiment, a rod material, a shaped steel material or the like may be used. Also,
In order to make the leg structure as compact as possible, the relationship between the front and rear leg spans l ₁ and l ₂ is set to l ₁ <l _{2 as} in the above embodiment.
Although it is desirable to set to _1, it is possible to set to l ₁ > l ₂ if necessary.

〔The invention's effect〕

As described above, according to the present invention, the front pillar to which the front top plate is attached and the rear pillar to which the rear top plate is attached are integrally formed in a state in which there is a space in the front and rear to form a front and rear two-post structure strut. Since one front leg body extending forward and two rear leg bodies extending to the rear left and right sides are provided at the lower part of the column, the user can attach both legs to the front column and the front leg of the column. It is placed on both left and right sides toward the table, and there is no constraint on the position and movement of the legs from the left and right sides as in the case of the left and right side strut structure.

In addition, since the load-supporting shaft is distributed to the front and back by the front and rear columns, the stability of the entire table is better and the load-bearing axis is better than that of the single-column structure shown in Japanese Utility Model Publication No. 61-33127. The performance is high.

This makes it possible to reduce the amount of forward protrusion of the front leg, and in combination with the fact that there is only one leg,
There is no risk that the front legs will hinder the position or movement of the legs.

That is, there is nothing that limits the position, movement, or opening of the legs. Therefore, the keyboard or the like can be operated in a comfortable and comfortable posture.

Moreover, as a general load distribution of this kind of table,
Since the front load is smaller than the rear load, one front leg can sufficiently support the front load.

In this case, since the front pillar and the rear pillar are formed as separate members, and these are connected by the connecting member to form the support pillar, it is relatively troublesome as compared with the case where the U-shaped support pillar is composed of, for example, one tubular body. Bending (bendering) is not required, resulting in high productivity.

Further, by forming the front pillar and the rear pillar as separate members, it is possible to make the diameters of these pillars different from each other in accordance with the loads applied to them and to use different materials for both pillars. In particular, if square pipes are used for both columns, curved surface processing of the end surface of the leg, which is required when using a round pipe, is not required, so that the leg can be easily processed.

Furthermore, as a means for attaching the leg to the column, the method according to claim 3
Alternatively, by adopting the configuration of 4, it is possible to obtain the same effect as described above.

Further, in the case of an OA table or the like, considering that the front load is generally smaller than the rear load, the relationship between the front protrusion amount l ₁ of the front leg body and the rear protrusion amount l ₂ of the rear leg body is set to l ₁ <l ₂ By setting to 1, the leg structure becomes compact, and the front leg is not obstructed more and more, and it becomes easier to use.
