Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure having a column and a bar supported by the column.

[0002]

2. Description of the Related Art With the recent promotion of OA, many wirings are overflowing in offices. In particular, wiring routed from under the floor or pulled down from the ceiling to the room tends to be exposed in an unsightly manner in the office space, and if the wiring crosses the passage or hangs from the ceiling, the function of the office will be degraded And may cause accidents.

[0003] On the other hand, recently, a structure has been known in which a specific work space is formed by a structure formed by supporting a bar on a support standing upright on an office floor surface. Work spaces with such a configuration have attracted attention because they allow flexible office layouts, but by providing a wiring guide function to the structure that constructs the work space, a clean office space that does not expose wiring It is also contemplated to form

[0004] In addition, for example, a computer, a lighting fixture, and the like, which require a large amount of wiring, are arranged on a desk, so that a leg structure consisting of a column and a bar supporting a top plate of the desk is installed from under the floor. It is also conceived to guide the established wiring.

[0005]

By the way, in a structure having such a structure (including a leg structure), members each having a different shape are generally applied to a column and a crosspiece. However, in such a structure, in order to form a continuous wiring guide path by the strut and the crosspiece so that the wirings are not exposed as much as possible, a recess formed by a groove, a notch, or the like is connected to each of the strut and the crossbeam after the connection. Such a structure has been devised from the design stage. In addition, regardless of the wiring guide function, in order to suitably connect columns and bars having different shapes, connecting members corresponding to those shapes are necessary, and the structure of the connecting members becomes complicated and Costs will also increase.

In order to solve such a problem, the present invention has a good wiring guide function while simplifying the structure by making the cross-sections of the support post and the crosspiece common, and has a good connection between the support post and the crosspiece. An object of the present invention is to provide a structure that can be easily connected.

[0007]

That is, a structure according to the present invention comprises a column and a bar supported by the column, and each of the column and the column has a recess extending in the longitudinal direction. Or, forming a ridge, and assuming that the cross-sectional shape in the direction orthogonal to the longitudinal direction of each of the strut and the crosspiece has the same shape, the strut and the crosspiece are connected in a state where the concave portion or the ridge is continuous. It is characterized by having.

With such a configuration, the columns and the crosspieces have a common cross-sectional shape, and the concave portions are formed in each of them, so that the concave portions can be connected to each other without special efforts from the design stage. Can be easily communicated with each other, so that the structure can easily have a wiring guiding function. In addition, when such concave portions or ridges are continuous, even when connecting the support and the beam using the connecting member, a member having a simple shape can be applied to the connecting member itself, and the structure can be simplified easily. It can also be planned.

In order to easily obtain such a structure,
It is preferable that the strut and the crosspiece have a cross-sectional shape such as each part along the longitudinal direction. In particular, if the strut and the crosspiece are made of the same material, for example, the extruded member is cut at an applicable location. Therefore, they can be used as columns and crosspieces, respectively, which can contribute to cost reduction.

Further, in order to connect the support and the beam using a connection member having a simple structure, the recess is formed in each of the support and the beam, and the vertical portion and the vertical portion of the L-shaped connection member are formed in these recesses. In a state where the horizontal portion is inserted, it is desirable that the column and the crosspiece are connected via the connecting member.

In this case, in order to easily improve the strength of the connection between the support and the crosspiece via the connecting member, the concave portions should each have a V-shaped cross-sectional shape, and the cross-sectional shapes of the vertical portion and the horizontal portion of the connecting member should be changed. It is effective to form a V-shape corresponding to each of the recesses to be inserted.

Further, in order to easily fix the connecting member to the column and the bar without forming unsightly screw holes or the like in the column and the bar, the connecting member is interposed between the column and the bar and the connecting member. It is only necessary to form auxiliary recesses into which nut members that can be screwed can be inserted so that they can be inserted and removed.

[0013] As a concretely preferable configuration of the strut and the crosspiece, a central body forming each core and at least a pair of arms protruding outward from the central body are provided. And the arm formed with the concave portion.

[0014] Further, when the connecting member is screwed to the auxiliary connecting member, a preferable configuration of the post and the crosspiece is a central body that forms the core of each, and at least a pair of arms that protrude outward from the central body. And a projection protruding from the center body and each arm so as to be opposed to each other. A portion outside the projection is a recess, and a space surrounded by the projection, the center body, and the arm is an auxiliary recess. And those that have been mentioned.

When the strut and the crosspiece are provided with the central body and the arm as described above, they can be arranged regardless of the direction around the vertical axis of the strut and the direction around the horizontal axis of the crosspiece. As a specific example that can be achieved, a plurality of arms each having the same shape protrude at equal intervals around a central body. By doing in this way, it becomes possible to attach a plurality of bars around one pillar at equal intervals or to arrange a plurality of pillars around the pillar.

In the above-described structure, when the recesses are formed in the columns and the crosspieces, even if the recesses are used as the wiring guide paths, the wirings are not unsightly exposed, and the recesses are formed even after the structure is constructed. In order to allow the wirings to be easily put in and taken out, it is preferable that a cover capable of concealing the concave portion be detachably attached to the support and the crosspiece. In this way, if the cover is attached and detached, maintenance of the wirings becomes easy.

It is designed to communicate with a drawer hole (not shown).

As described above, in the structure 1 of the present embodiment, since the cross section of the support 2 and the crosspiece 3 are made the same and the recesses S extending in the longitudinal direction are formed respectively, for example, FIG.
Also, as shown by imaginary lines in FIG. 4, if the wirings H drawn from the floor F or the ceiling are passed through the recesses S, the recesses S can be used as suitable wiring guide paths. In particular, the support 2 and the cross 3
Are connected to each other, the wirings H can be routed over both the column 2 and the bar 3 through a continuous space formed from the column 2 to the bar 3 by the concave portions S.
In particular, as shown in FIG. 1, when the structure 1 is to form a work space of an office, the structure 1 is pulled out from the floor surface F or the ceiling (not shown) with respect to the concave portion S of a certain column 2. Since the wirings can be guided to another support 2 by passing through the concave portion S of the crosspiece 3, the wirings do not appear unnaturally, which is useful for preventing accidents.

Further, since the strut 2 and the crosspiece 3 have the same cross-sectional shape along the longitudinal direction by extruding the same material, the strut 2 can be formed by cutting one material to an appropriate length. Since the bar 3 can be used, the manufacturing cost can be reduced.

Further, the connection can be made by inserting a connection member 7 having a simple L-shaped structure into the recess S communicating with the column 2 and the bar 3. Especially the cross section V of the concave portion S
Since the vertical portion 71 and the horizontal portion 72 of the connecting member 7 also have a V-shaped cross section corresponding to the concave portion S, the connecting member 7 is
In addition, the two portions of the horizontal portion 72 are brought into contact with each other to improve the connection strength. Further, since the concave portion S and the connecting member 7 are formed in such a shape, even if the connecting member 7 is inserted into the concave portion S, the concave portion S connected to the support 2 and the bar 3 is closed by the connecting member 7. Therefore, the function of guiding the wiring of the recess S communicating as described above is not impaired.

Further, when the connecting member 7 is fixed to the support 2 and the crosspiece 3, respectively, the support recess 2
Is formed, and the nut member 8 inserted into the auxiliary concave portion T,
9 is interposed between the connecting member 7 and the column 2 and the bar 3, and is fixed to the nut members 8 and 9 by the bolts B from the connecting member 7 side, so that the column 2 and the bar 3 are unsightly. The two can be easily connected without processing the screw holes and the like, and the wiring guide function by the concave portion S of the column 2 and the bar 3 is not adversely affected.

As a specific configuration of the column 2 and the bar 3, four centrally-arranged arms 5, each of which has a square cross section as a main body, are provided at equal intervals from the central body 4 outward. The recess S is formed between the center body 4 and a pair of adjacent arms 5, and the center body 4
And a projection 4 projecting from each arm 5 so as to face each other.
Since the space surrounded by 2, 53, the center body 4, and the arm 5 and closer to the center body 4 than the recess S is the auxiliary recess T, the connecting member 7 and the nut members 8, 9 are used with a very simple configuration. In addition to connecting the support 2 and the crossbar 3 with each other, the support 2 and the crossbar 3 can be arranged irrespective of the direction around the axis passing through the center thereof, so that the construction is simplified and Up to four crossbars 3 around column 2
Can be connected at equal intervals.

Further, since the cover 6 capable of concealing the concave portion S is detachably mounted on the column 2 and the crosspiece 3, respectively, even if the wirings H are guided to the concave portion S, they are covered with the cover 6. By doing so, it is possible to keep the appearance good and hardly to expose the wiring H. Also, if the cover is attached and detached, the wirings H can be easily taken in and out of the recess S even after the construction of the structure 1 and maintenance can be performed. Can be.

The present invention is applied not only to the structure for constructing the work space module described above, but also to a leg structure for supporting a top plate such as a desk or a table. Is what you can do. In addition, when a ridge extending along the pillar or the bar is formed in addition to forming the recess, the L-shaped bracket or the like having a flat plate shape is applied to the ridge to improve the appearance of the pillar. And the crosspiece can be easily connected. In addition, the specific configuration of each unit is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0036]

That is, the structure of the present invention has the same cross-sectional shape in the direction perpendicular to the longitudinal direction of the strut and the crosspiece, and forms a concave portion or a ridge extending in the longitudinal direction, respectively. In this state, the support and the crosspiece are connected. For this reason, compared with the case where the support and the crosspiece have different cross-sectional shapes, for example, when the support and the crosspiece are connected using the connection member, the connecting member having a simple configuration can be applied. In addition, it is possible to effectively reduce the labor and cost of design and construction, and if the structure has a function to guide the wiring drawn from the floor or ceiling,
By forming the recesses of the same shape on the support and the crosspiece, it is possible to form a space continuous with the support and the crosspiece,
It is possible to easily form a suitable wiring guide path.

In such a structure, as long as both the support and the crosspiece have the same cross-sectional shape along the longitudinal direction, the above-described effects can be obtained easily and various sizes can be easily obtained. In particular, if the support and the crosspiece are extruded materials of the same material, the same member can be applied to the support and the crosspiece, so that the cost can be effectively reduced.

Further, if the recesses are formed in the columns and the bars, respectively, and the connection is made in a state where the L-shaped connecting member is inserted into these recesses, the shape of the connecting member can be made extremely simple.

In particular, if the cross-sectional shape of the concave portion of the support and the crosspiece is V-shaped and the cross-sectional shape of the portion of the connecting member inserted into the concave portion is also the V-shape corresponding to the concave portion, the connecting member has two surfaces on the support and the crosspiece, respectively. As a result, the connecting strength can be improved, and the concave portion functioning as a wiring guide path can be connected to the support and the bar without being interrupted by the connecting member.

Further, an auxiliary recess is formed in the support and the crosspiece, and a nut member is inserted into the auxiliary recess so that the nut member is interposed between the support and the crosspiece and the connection member, and the connection member is screwed to the nut member. If it stops, a support | pillar and a cross | pipe can be easily connected using a connection member, without having to process unsightly screw holes etc. in a support | pillar and a pavement.

More specifically, the column and the crosspiece are each formed by projecting at least a pair of arms outwardly from the center body with the center body as a main body, thereby allowing the center body and the adjacent pair of arms to protrude. The recess can be easily formed in the recess. Further, in such a configuration of the strut and the crosspiece, when the strut and the crosspiece are connected by screwing the connecting member to the nut member as described above, the protrusions protruding from the center body and the respective arms so as to face each other. Is formed, and the space outside the protrusion, the central body, and the arm is set as the auxiliary recess, so that the connecting member and the nut member can be easily inserted into the column and the crosspiece. Can be.

In such a case, if a plurality of arms each having the same shape are protruded at equal intervals around the center body, the struts and the crosspieces are arranged regardless of the direction around the axis passing through their centers. Therefore, the construction can be simplified, and furthermore, a plurality of bars can be attached around one pillar at equal intervals, or a plurality of pillars can be arranged around the pillar.

In the above-described structure, if the support and the crosspiece are formed with recesses, respectively, and a cover capable of concealing the recesses is detachably attached to the support and the crosspiece, the wirings are accommodated in the recesses. Even if the cover is attached and detached, maintenance and replacement can be easily performed after installation of the structure, such as putting in and out wiring in the recess, even if the cover is attached and detached. It is possible.
