TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a structure that is installed indoors or outdoors for various uses.
[0002]
[Prior art]
An open structure was proposed in which the upper ends of the columns were connected with horizontal beams (cross beams) in order to provide spaces for various uses, such as a conversation space, a rest space, an office space, and a meeting space, both indoors and outdoors. ing.
[0003]
This type of structure includes mounting a table or planter on a column, installing a table or chair inside a column surrounded by columns, hanging a board on a horizontal beam, or mounting a panel on an adjacent column. Thus, it is used for various purposes by attaching and installing other furniture and articles.
[0004]
Patent Literature 1 describes a structure in which three columns are connected to each other by a horizontal beam to form a triangular shape in a plan view as a minimum unit, and a plurality of units are connected in various modes. .
[0005]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2000-138692
[Problems to be solved by the invention]
Since this type of structure is installed in an existing building by retrofitting, the height of the horizontal beam is necessarily lower than the ceiling.
[0007]
On the other hand, in Patent Literature 1, the horizontal beam in each unit has a loop shape in plan view. Therefore, the user always passes through the horizontal beam as if to pass through the gate, so as to go in and out of the inside surrounded by the column.
[0008]
And, as described above, since the height of the horizontal beam is lower than the ceiling, the configuration of Patent Literature 1 has a problem that the user is likely to feel oppression. In addition, since one unit has an isosceles triangular shape in plan view, there is a problem that it is difficult to freely set the interval between the columns and the arrangement of the columns. Further, there is a problem that the configuration is complicated due to the large number of horizontal beams.
[0009]
An object of the present invention is to provide a structure in which such a problem is improved.
[0010]
[Means for Solving the Problems]
According to the first aspect of the present invention, in the structure including three or more columns that are erected from each other and a horizontal beam group that connects upper ends of the columns, the column group includes a plurality of horizontal columns. It is composed of an intermediate column to which beams are connected and an end column to which one horizontal beam is connected.
[0011]
According to a second aspect of the present invention, in the first aspect, furniture with legs such as a table or a chair is fixed to at least an end column of the column group.
[0012]
According to a third aspect of the present invention, in the second aspect, the furniture legs fixed to the end support are arranged at least on both sides or one side of the horizontal beam in plan view.
[0013]
[Action and Effect of the Invention]
According to the present invention, even if the number of columns is the same as that of Patent Document 1, the number of horizontal beams is small, so that it is possible to significantly suppress the user from feeling oppressed. In addition, since the end support is merely connected to the intermediate support by one horizontal beam, it is easy to change the distance between the end support and the intermediate support and the position of the end support.
[0014]
According to the second aspect of the present invention, since the legs of the furniture perform the function of resisting the falling of the end support, the end support is connected to one horizontal beam. Sex can be significantly improved.
[0015]
Since the end support is weak against an external force such that the end support is tilted to both sides sandwiching the horizontal beam in a plan view, the configuration according to claim 3 is preferable because the stability can be particularly improved.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings.
[0017]
(1). First Embodiment (FIGS. 1 to 10)
First, a first embodiment will be described with reference to FIGS. 1A is a schematic perspective view, and FIG. 1B is a schematic plan view. As shown in FIG. 1, the structure includes a group of a plurality of (six) columns 1, 2 and a group of horizontal beams 3 connecting adjacent columns 1, 2 at an upper portion thereof. .
[0018]
There are two types of support columns: two intermediate supports 1 to which three horizontal beams 3 are connected, and end supports 2 to which only one horizontal beam 3 connected to the intermediate support 1 is connected. The table 4 is fixed to the end support 2.
[0019]
The three horizontal beams 3 extending from the intermediate support 1 extend at intervals of 120 degrees in plan view. A small shelf board 28 can be detachably attached to each of the columns 1 and 2 via a bracket (not shown). Next, details of each part will be described with reference to the drawings in FIG.

(B) is a bottom view as viewed from the line BB in (A).
[0021]
As shown in FIG. 2, the columns 1 and 2 each include a hollow inner member 5 having a substantially triangular shape in plan view and three outer members 6 arranged outside the inner member 5. A dovetail-shaped engaging portion 7 is formed in a portion of the inner member 5 that forms the base of the triangle in plan view.
[0022]
On the other hand, the outer member 6 has a hollow shape as a whole, and has a shape in which the outer portion of the radius is wide, and the inner portion of the inner member 5 is provided with a dovetail-shaped engaging portion 7 And a convex engagement portion 8 which engages with and disengages from the main body. In the outer peripheral portion of the outer member 6, first vertically extending dovetail grooves 9 are formed symmetrically on both sides of the center line.
[0023]
A wiring space 11 opened outward is provided between the adjacent outer members 6, and the wiring space 11 is removably closed by a cover 10 having an arc shape in plan view. On both longitudinal side surfaces of the cover 10, engagement claws 10 a engaging and disengaging from the step portions 6 a of the outer member 6 are provided.
[0024]
In the inner member 5, a first arc groove 13 is provided in a portion near the vertex of the triangle in a plan view, and a second arc groove 14 and a third arc groove 15 are provided in a radially intermediate portion of the outer member 6. The inner member 5 and the outer member 6 are fixed to the support plate 18 of the adjuster receiver 17 by screws 16 formed respectively and screwed into the first circular groove 13 and the second circular groove 14.

As shown in FIG. 5, a downward cylindrical portion 19 and an adjuster bolt 20 are fixed to a support plate 18 of an adjuster receiver 17, and the adjuster bolt 20 is screwed into a nut plate 22 of an adjuster 21. A cylindrical portion 23 is integrally fixed to a nut plate 22 of the adjuster 21, and the cylindrical portion 23 is fixed to a base plate 24.
[0026]
Therefore, the height of the columns 1 and 2 can be adjusted by rotating the adjuster 21 horizontally. Note that the base plate 24 can be fixed to the floor with an anchor. In addition, the stability of the columns 1 and 2 may be improved by making the base plate 24 have a large area.
[0027]
For example, as clearly shown in FIG. 3, a wiring path 25 communicating with the wiring space 11 is formed in the support plate 18 of the adjuster receiver 17 by opening. Since cables 26 for power supply, communication, etc. are often pulled out onto the floor from a duct buried in the floor, the cables 26 pulled out (or crawled) on the floor are connected to the wiring passage 25 and the wiring space 11. And can be pulled out on the table through. The wiring work can be easily performed by removing the cover 10.
[0028]
The inner member 5 and the outer member 6 are extruded products made of a light alloy such as aluminum, but may be made of sheet metal. In addition, although the cover 10 employs an extruded product of a synthetic resin, it can also be made of sheet metal.
[0029]
▲ 2 ▼. Table The table 4 includes three top plates 39 and legs 30 that support them. The top plate 28 extends at an angle of 120 degrees in plan view, and has a circular shape as a whole. There is a certain space between the top plate 28 and the columns 1 and 2 so that the cables 26 can be pulled out.
[0030]
On the other hand, the leg 30 includes a horizontal portion 30 a extending along the lower surface of the top plate 28, a support foot 30 b fixed to the tip thereof, and a vertical mounting portion 30 c overlapping the outer surface of the outer member 6 in the columns 1 and 2. And a reinforcing rod 38d for connecting the mounting portion 30c and the support foot portion 38b, and the horizontal portion 38a of one leg 30 is disposed so as to straddle the two top plates 39.
[0031]
The bracket plate 31 fixed to the horizontal portion 30a is fixed to the top plate 39 with screws. Therefore, the three top plates 28 are connected as a single plate as a whole, and are supported by three legs 30. The mounting portion 28c has a width that closes the first dovetail groove 9 of the outer member 6 in the columns 1 and 2, and the screw 32 penetrating the mounting portion 38c is screwed into the plate nut 33 fitted in the first dovetail groove 9. Thereby, the leg 30 is fixed to the end support 2.
[0032]
One of the three legs 30 extends so as to overlap the horizontal beam 3 in plan view, and the other two legs 30 extend so as to extend outside the horizontal beam 3 in plan view. I have.
[0033]
When pulling out the cables 26 from the wiring space 11 onto the table, the cover 10 may be separated vertically and the cables 26 may be drawn out between the vertically separated covers, or the cover 10 may be partially cut out. The cables 26 may be pulled out from the notch.
[0034]
Note that various methods can be adopted for the form of the table 4 and the method of attaching the table 4 to the columns 1 and 2. For example, the top plate does not need to be a three-piece set, but may be a two-piece set or a donut-shaped single piece. Further, the shape need not be circular, but may be semicircular or fan-shaped. As in the present embodiment, when the table 4 in which the plurality of top plates 28 are connected is formed in a donut shape as a whole, the table 4 can be attached and detached in a state where the end support 2 is erected. It is.
[0035]
Further, the legs may be simply fixed to the lower surface of the top plate 28. Although it is possible to simply install the table 4 on the floor without fixing the table 4 to the end support 2, when the table 4 is fixed to the end support 2 as in the present embodiment, they reinforce each other and greatly improve the stability of both. Can be done.
[0036]
Further, the end support 2 is weak against an external force acting from a direction crossing the horizontal beam 3 in a plan view, but in the present embodiment, two legs 30 are arranged on both sides of the horizontal beam 3 in a plan view. Therefore, the stability can be significantly improved. When the table 4 is large, the number of the legs 30 may be increased.
[0037]
Although not described in detail, the above-described plate nut 33 or a hanging plate having a large number of engagement holes is fitted into the first dovetail groove 9 of the outer member 6, and a bracket is attached to the plate nut 33 or the hanging plate. The first dovetail groove 9 of the outer member 6 is used to fix or lock the small shelf board 28 with the bracket or to attach a monitor (display) such as a liquid crystal. Can be used for mounting.
[0038]
(3). Next, a connection structure between the columns 1 and 2 and the horizontal beam 3 will be described with reference to FIGS.
[0039]
6 is a plan view at the position of the intermediate support 1, FIG. 7 is a separated front view, FIG. 8A is a plan view taken along the line VIII-VIII in FIG. 7, and FIG. 8B is a bottom view taken along the line VIII-VIII in FIG. FIG. 9 (C) and FIG. 9 (D) are plan views of other connecting brackets, FIG. 9 (A) is a sectional view taken along IXA-IXA of FIG. 6, and FIG. 9 (B) is a sectional view taken along IXB-IXB of FIG. FIG. 4 is a perspective view of a reinforcing member.
[0040]
As shown in FIG. 9, the horizontal beam 3 is formed as a hollow substantially rectangular shape as a whole, and has a first upward opening groove 35 extending along the longitudinal center line and second upward openings formed on both sides thereof. It has a groove 36, a second dovetail groove 37 opened on both side surfaces, and a third dovetail groove 38 opened downward.
[0041]
The cables 26 can be routed in each of the upward opening grooves 35 and 36. In the second and third dovetail grooves 37 and 38, various articles and devices such as projection curtains, blindfold curtains, curtains, and white boards can be hung.
[0042]
In connecting the intermediate support 1 and the horizontal beam 3, an intermediate connection fitting 39 shown in FIGS. 6 to 9 is used. The connecting fitting 39 has a hexagonal foot 40 with a flat cross section that fits tightly into the columns 1 and 2 from above, and three horizontal tubular arms that fit into the ends of the horizontal beams 3. The horizontal beam 3 is fixed to the horizontal arm 41 with a screw 42.
[0043]
As shown in FIG. 9A, the end of the lower plate 38a constituting the third dovetail groove 38 in the horizontal beam 3 is cut out so that the horizontal arm 41 of the connecting fitting 39 is fitted. A downward opening 43 is formed at an end of the connection fitting 39. For this reason, the horizontal beam 3 can be attached with the columns 1 and 2 fixed at predetermined positions.
[0044]
The end connection fitting 39 ′ for connecting the end support 2 and the horizontal beam 3 has a shape having one horizontal arm 41 as shown in FIG. 8C. Also, in the case of a connecting bracket 39 ″ for attaching two horizontal beams 3 to one intermediate support in a V-shape in plan view, as shown in FIG. The shape has the portion 41.
[0045]
For example, as shown in FIG. 7, a notch 5 a having an upward opening into which the arm 41 of the connection fitting 39 is fitted is formed in an upper portion of the inner member 5 in the columns 1 and 2. For this reason, the connection fitting 39 is precisely positioned.
[0046]
The horizontal beam 3 is arranged so as to abut the side surface of the inner member 5, and therefore, as shown in FIG. 7, the upper part of the inner member 5 projects upward from the outer member 6 and the cover 10. Therefore, if the state in which the horizontal beams 3 intersect is left exposed, the appearance is poor.
[0047]
Therefore, the base of each horizontal beam 3 is hidden by a cylindrical top cap 44 having the same radius of curvature as the outer member 6 and the cover 10. Therefore, a notch 45 having a downward opening that fits into the horizontal beam 3 is formed in the top cap 44. The top cap 44 may be opened vertically, or the top surface may be closed by a top plate.
[0048]
The horizontal beam 3 connected to the intermediate column 1 can be fixed and reinforced by a reinforcing member. One example is shown in FIGS. 6, 9, and 10. FIG. That is, the reinforcing member 46 is provided with a pair of fitting portions 46a that cover the second upward opening grooves 36 of the adjacent horizontal beams 3, and this fitting portion 46a is formed by the second upward opening of the horizontal beam 3. It is fixed with a screw 47 to a plate nut 48 fitted in a dovetail groove in the groove 35.
[0049]

10 to 11 show a second embodiment. In this embodiment, four horizontal beams 3 extend radially in a plan view from one intermediate support 1, and a table 4 is attached to each end support 2.
[0050]
In this embodiment, each of the columns 1 and 2 is the same as the first embodiment in that the columns 1 and 2 are composed of an inner member 5 and an outer member 6, but the inner member 5 is formed in a hollow square shape. Thus, there are four outer members 6 and four covers 10.
[0051]
The table 4 has a semicircular top plate 28 divided into two parts, and is supported by two legs 30. In this embodiment, the horizontal beams 3 can be freely combined based on a right-angled posture in plan view, such as a T-shape or L-shape in plan view.
[0052]
(3). Other Embodiments (FIGS. 12 to 13)
In the structure of the third embodiment shown in FIG. 12, a long table 4 is fixed to one end support 2 and an intermediate support 1, and a chair (sofa) 48 is fixed to the other supports 1 and 2. Although details are omitted, the chair 48 is fixed to the columns 1 and 2 via a bracket. The structures of the columns 1 and 2 are the same as those of the first embodiment (other structures may be used).
[0053]
The structure of the fourth embodiment shown in FIG. 13 is configured such that the horizontal beam 3 extends in a zigzag manner. In the fifth embodiment shown in FIG. 14, the four intermediate posts 1 are connected by the horizontal beam 3 so that the four horizontal beams 3 are connected in a loop shape. The end columns 2 are connected to each other via one horizontal beam 3, and a table 4 having a rectangular shape in a plan view is attached to both end columns 2.
[0054]
(4). Others The present invention can be embodied in various ways other than the above. For example, in each embodiment, the space below the horizontal beam is a space where people can walk freely, but it is also possible to attach a wall panel.
[0055]
Further, the cross-sectional shape of the horizontal beam, the connection structure with the columns, and the like can be variously embodied as necessary. In addition, a cabinet, a shelf, or the like can be fixed to the support column in addition to a desk or a chair.
[0056]
(5). Reference example (Fig. 15)
In the first embodiment, the two horizontal beams can be fixed to the intermediate support in a state of being widened by 120 degrees in plan view. As shown in Fig. 7, a hexagonal frame-like structure in a plan view can be constructed.
[0057]
Although there are various uses of this structure, in this drawing, one of the six surfaces is used as an entrance and the other surface is provided with a wall member 49. The wall material 49 may be an opaque panel, a transparent or translucent plate such as glass, a transparent or translucent screen, or a combination of these materials.
