Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a table leg assembly, and more particularly to a variable shape table leg assembly whose shape can be appropriately changed according to the planar shape of a table top plate.
[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 various events, events, meetings, etc. in hotels, banquet halls, conference halls, etc. In addition, a table with a different shape may be required in terms of the atmosphere of the place of use. .
[0003]
In response to such demands, usually, a table having a fixed shape, each having a different shape, is prepared, and measures are taken to use these 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 vast space for storing unnecessary tables, and a storage room away from the place of use, such as a basement or a separate warehouse, is required. It was uneconomical.
[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 foldable table has various difficulties 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 is not easy to get.
[0005]
In addition, even if it is a foldable type, storage is somewhat advantageous, but the shape of the table top is fixed, and it is difficult to select and use a table of any shape that suits the atmosphere and application. is there.
[0006]
[Problems to be solved by the invention]
The present invention has been made in consideration of the above circumstances, and various types of table tops are prepared and adapted to the table tops of arbitrary shapes as necessary, so that they can be adapted to applications and atmospheres. It is an object of the present invention to provide a variable shape table leg assembly capable of forming tables having different shapes.
[0007]
[Means for Solving the Problems]
As shown in FIG. 3, the above-described problem of the present invention is that the angle of N table legs 10 having an equal length (here, an even number of N ≧ 4) and these adjacent table legs can be changed. The table is formed by appropriately changing the included angle formed by the horizontal bars 18 located at the left and right of the table legs 10 with the table legs 10 as apexes. In the variable shape table leg assembly in which the top shape of the top plate can be changed, the table leg 10 includes a screw hole for receiving the adjuster 10C downward and a screw for receiving the rotation center body 12 at an upper end thereof. A lower assembly 10B, each having a hole 14 and having a first crosspiece 18 secured between corresponding portions of adjacent table legs, and the rotating center body 12 are received. And an upper assembly 10A to which a second crosspiece 18 connected to a corresponding portion of an adjacent table leg is fixed, and a rotation center body 12 extends downwardly. This is solved by a variable shape table leg assembly having a body with a top member 16 that connects the upper and lower assemblies through a through-hole formed in the upper assembly.
[0008]
The table legs 10 constituting the variable shape table leg assembly according to the present invention may be any one of a polygonal column such as a hexagonal column and an octagonal column as well as a cylinder and a quadrangular column. Also, the material can be appropriately selected as metal, plastic, wood, a combination thereof, or the like. However, as will be described later, the table top plate disposed 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 plywood, and the like. Depending on the size of the table, it can be quite heavy. Therefore, the table leg should be selected to maintain the appropriate strength.
[0009]
The cross rail 18 has a function of preventing a situation in which a torsional moment is generated by an imbalance acting force applied to the table leg 10 and the whole table leg assembly is distorted and falls down in the case of a fragile material. These horizontal rails should be firmly attached to the table legs by welding or the like. Further, these horizontal rails can be formed so as to be connected by a pair of upper and lower horizontal rails so that the upper and lower portions of the table legs are connected to each other. In this way, a plurality of horizontal rails can be attached to the table legs.
[0010]
The number of table legs and the number of horizontal bars N are an even number of 4 or more. In the case of 4, the shape of the table top is limited to a square and a diamond. Therefore, by setting N to 6 and using the horizontal rail as an isometric member, a table having a regular triangle, a rectangle having an aspect ratio of 1: 2, a regular hexagon, and a regular octagon can be easily formed. 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
[0011]
In the structure that is placed on the upper end surface of the table leg 10, the table top plate has a larger area than the projected area formed by the entire table leg assembly, or an area substantially equal to the table leg assembly. Can be. Further, although the structure is slightly complicated, the number of legs N can be 8 or more.
[0012]
Further, as shown in FIG. 4, the object of the present invention is to change the angles of N table legs 10 having an equal length (here, N ≧ 4 even number) and the adjacent table legs. By appropriately changing the included angle formed by the horizontal bars 18 located on the left and right of the table legs 10 as apexes, In the variable shape table leg assembly in which the planar shape of the table top plate can be changed, the table leg 10 has a screw hole for receiving the adjuster 10C on the lower side, and a bolt head constituting the rotary center body 12 on the upper side. 24, and a lower assembly 10B to which the first crosspiece 18 connected to the corresponding portion of the adjacent table leg is fixed, and a through hole for receiving the rotating center body 12 are formed. And an upper assembly 10A to which the second crosspiece 18 connected between the corresponding portions of the adjacent table legs is fixed, and a nut 25 having a screw hole for receiving the end of the rotation center body below, A variable shape table leg assembly comprising: a leg top member 16 that connects the upper assembly and the lower assembly via a through-hole formed in the upper assembly by tightening the nut. Solved.
[0014]
Further, the table leg top member 16 according to the present invention is provided with a dowel 19 for rotatably disposing a support bracket 17 for placing the table top plate and locking the table top plate on the upper end surface. It is characterized by that.
[0015]
A coil spring 11 is disposed around the rotation center body 12 according to the present invention and inside the through hole of the upper assembly 10A so as to separate the lower assembly and the lower assembly from each other. Further, when the leg top member 16 is loosened, it is easy to change the included angle formed by the cross rails 18 connected to the two assemblies. In the present invention, display means for indicating a relatively narrow angle between the horizontal bars can be provided at appropriate portions of the horizontal bars, the lower assembly, and the upper assembly. This facilitates the positioning of the cross rails 18 for configuring a desired table plane shape.
[0016]
According to the table leg 10 having such a configuration, the planar shape of the table top plate placed on the variable shape table leg assembly according to the present invention can be changed as appropriate, and both side rails 18 stabilize the leg assembly. At the same time, it is possible to easily position the both cross beams by determining the relative included angle between the cross beams required for each target shape, and to form a desired planar shape.
[0017]
By arranging various tabletops such as equilateral triangle, circle, ellipse, rectangle, rhombus, etc. for one table leg assembly having such a configuration, the purpose, application, and installation location of the table can be determined. The effect that the table shape suitable for a floor area, the number of users, 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.
