Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a variable shape table leg assembly whose shape can be changed as appropriate according to the planar shape of a table top plate, and in particular, the leg body is configured as a connecting member of a plurality of members having strength. The present invention relates to a table leg assembly having a variable height.
[0002]
[Prior art]
As the planar shape of a normal table top plate, various shapes such as a square, a rectangle, a circle, an oval shape, an ellipse and the like are widely known, and are usually assembled in any specific shape. However, functional shapes differ depending on the use of various events, events, meetings, etc. in hotels, banquet halls, conference halls, etc. In addition, there are cases where tables with different shapes are also required in terms of the atmosphere of the place of use. is there.
[0003]
In response to such a demand, usually, various types of tables having different shapes have been prepared, and measures have been taken to use them as needed. However, a great deal of labor and time is required to replace such a fixed-shaped table each time. In addition, an ordinary fixed table requires a large space for storing unnecessary tables, and a storage location far away from the place of use, such as a basement or a warehouse, is uneconomical. there were.
[0004]
When used in a conference room, a meeting place, a lobby, etc., the table is often folded and cleared when not in use, and is unfolded and arranged when in use. However, this type of folding table has various weaknesses in the folding mechanism, is likely to cause rattling and abnormal noise, and has a high-class feeling suitable for use in banquet halls and hotels that emphasize the atmosphere. It's not easy to get.
[0005]
In consideration of such circumstances, the top plate and the table leg assembly are configured as separate bodies, and the shape and size of the top plate can be changed. However, the length of the table leg and therefore the height of the table is It was decided at the time of manufacturing the assembly, and it was difficult to change it arbitrarily after that.
[0006]
[Problems to be solved by the invention]
The present invention has been made in consideration of the above circumstances. By preparing a table top plate of various shapes and adapting it to a table top plate of an arbitrary shape as necessary, it can be adapted to the application and atmosphere. It is an object of the present invention to provide a table leg assembly capable of forming a table having a shape and a height, and having a table top plate shape and a table height variable.
[0007]
[Means for Solving the Problems]
The above-mentioned problem of the present invention is N (in this case, N ≧ 4) table leg bodies having equal lengths, each of the table leg bodies having a plurality of members 10U, 10M, 10D,. The table leg main body 10 that can be formed by connecting the two, and at least N horizontal rails 18 that connect these adjacent table legs to each other in a state in which the angle can be changed, are developed in an appropriate shape. In the table leg assembly on which the top plate corresponding to the upper part is placed, the intermediate connecting member 10M forming the table leg main body has a through bolt 20 penetrating through the center, and a space is formed on the outer periphery of the through bolt. This is solved by a table leg assembly of variable shape and height, in which a pipe 30 made of metal or reinforced plastic is penetrated and an exterior member 33 is formed outside the pipe.
[0008]
A table leg body 10 comprising a plurality of members connected to form a table leg assembly having a variable shape and height according to the present invention includes not only a cylinder or a quadrangular column, but also a polygonal column such as a hexagonal column and an octagonal column. It may be any, may have a different shape for each of the plurality of members, or may have a different color for each of the plurality of members.
[0009]
In addition, the constituent materials constituting the table leg assembly according to the present invention can be appropriately selected as metal, plastic, wood, a combination thereof, and the like. However, as will be described later, the table top plate placed on the upper portion of the table leg is composed of a heavy glass plate, a processed marble stone plate, a hardwood wood plate, a laminated wood plate, a plastic plate, a decorative plywood, and the like. Depending on the size of the table, it can be quite heavy. Therefore, the table leg main body 10 should be configured by selecting a plurality of members that retain appropriate strength.
[0010]
The crosspiece 18 is required to have a function of withstanding a torsional moment generated by an unbalanced force applied to the table leg body and preventing a situation where the entire table is toppled. It is necessary to firmly attach these horizontal rails to the table legs by welding or the like. Thus, a plurality of horizontal rails attached between the table legs, such as up and down or upper, middle, and lower, can be set to an integer (2 or 3) times N.
[0011]
The number of table legs and the number N of cross rails are integers of 4 or more, but in the case of 4, the shape of the table top plate is either square or rhombus. Therefore, by setting N to 6 and using the horizontal rail as an isometric member, it is possible to easily form a regular triangle, a rectangle having an aspect ratio of 1: 2, a regular hexagon, and a regular octagon. Furthermore, in order to support the table top plate, the structure is placed on the upper end surface of the table leg, the support bracket 17 is attached to the inner side surface slightly lower than the upper end of the table leg, and the upper surface of the table top plate is attached to the upper end surface of the table leg. It is possible to adopt a structure that fits the
[0012]
In the structure that is placed on the upper end surface of the table leg body, the table top plate has a larger area than the projected area formed by the developed table leg assembly as a whole, or has an approximately equal area. It is optional.
[0013]
Further, although the structure is slightly complicated, the number of legs N can be 8 or more. Such increase / decrease of the table leg and the horizontal beam N connect the upper assembly and the lower assembly, which are substantially U-shaped by connecting the two leg bodies divided vertically with one horizontal beam, respectively. In this case, it can be easily handled by increasing or decreasing one set at a time.
[0014]
Further, the table leg main body constituting the table leg assembly of variable shape and height according to the present invention is connected by interposing at least one connecting member having a length selected as required in the middle of the table leg main body. Thus, a favorable effect can be obtained by the table leg assembly having a variable shape and height. A plurality of such connecting members having different lengths are prepared, and one or a plurality of selected members are used in combination. However, there are many variations in colors, shapes, and the like. Depending on the customer's selection, it can be exchanged as appropriate.
[0015]
The intermediate connecting member 10M forming the table leg main body has a through bolt 20 penetrating in the center, a space is formed on the outer periphery of the through bolt, and a pipe 30 made of metal or reinforced plastic is passed through. It can be set as the structure which formed the exterior | packing material 33 in the outer side. Further, the through bolt 20 and the pipe 30 constituting the intermediate connecting member 10M can be configured to be supported and fixed by nuts 32 via washers 31 at the upper and lower ends of the intermediate connecting member. In addition to the nut 32, a nut for supporting and fixing the through bolt 20 can be further disposed outside the nut 32.
[0016]
By configuring the intermediate connecting member in such a configuration, the table leg main body 10 to which these are connected can maintain high strength, and the raw material of the exterior material 33 can be reduced, so that the cost can be reduced. In addition, the member of such a configuration can also be applied to simple pillars such as columnar ornaments, ornamental pillars, indoor partitioning pillars, and the like.
[0017]
Furthermore, it is desirable to provide an adjuster 10C for finely adjusting the height of the unevenness of the installation floor at the lower end of the table leg main body constituting the shape and height variable table leg assembly according to the present invention.
[0018]
According to the table leg assembly having such a configuration, the shape according to the present invention and the planar shape and / or height of the table top plate placed on the table leg assembly having a variable height can be appropriately changed. In addition, both crosspieces stabilize the leg assembly and determine the relative included angle between both crosspieces for each desired shape, making it easy to position both crosspieces in the desired planar shape. Can be formed.
[0019]
By arranging various top plates such as equilateral triangle, circle, ellipse, rectangle, rhombus, etc. for one table leg assembly having such a configuration, the purpose of use, application, floor area of installation location, The effect that the table shape suitable for the number of users, atmosphere, etc. can be selected suitably is acquired. In addition, the table leg assembly and the table top plate can be easily removed, the table leg assembly can be deformed into an elongated shape, and the table top plate is a flat plate. It can be stored on top of each other.
