Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hinge apparatus for a table,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table hinge apparatus and a table having the same, and more particularly, to a table hinge apparatus capable of performing a folding and rotating operation of a member for performing a folding operation, And more particularly, to a table hinge apparatus capable of preventing deformation or damage in a process and improving durability and a table having the table hinge apparatus.

In general, a table can be divided into a general desk used in the home or office, and a seminar table used in a classroom or a conference room.

The table for seminar is easily folded when not in use and stored in corner or warehouse of the lecture room, and the structure is relatively simplified by eliminating the drawer or the side plate so that it can be installed and used promptly during use.

As a table for such a seminar, a height adjusting and folding table disclosed in Korean Patent Registration No. 10-1068110 has been proposed.

1A, a plurality of legs 120a and 120b are mounted on a lower portion of a top plate 110 and a front plate 130 is installed on a front surface of the top plate 110 And a height adjusting unit 200 is provided in the middle of each of the legs 120a and 120b to adjust the height of the legs 120a and 120b.

The front shielding plate 130 is foldably connected to the front side of the upper plate 110 so that the front shielding plate 130 is spaced apart from the plurality of fixing plates 410 fixedly attached to the lower surface of the upper plate 110 A plurality of second fixing bars 412 extending from the upper edge of the front shielding plate 130 and positioned inside the first fixing bars 412, respectively, And the fixing bars 422 are rotatably mounted through the respective rotating pins.

As shown in FIG. 1B, the front shielding plate 130 is formed by punching convex hemispherical steps 426a and 426b inside the flanges 414a and 414b of the first fixing bar 412 And prevents the second fixing bars 422, which are formed opposite to each other and located inside the first fixing bars 412, from being separated from the outside.

When the user pushes the second fixing bar 422 from the first fixing bar 412 and folds or unfolds around the rotating pin 424, the hemispherical steps 426a and 426b are moved The flanges 414a and 414b on both sides of the bar 412 are configured such that the second fixing bar 422 can be folded or unfolded outwardly of the first fixing bar 412 while being elastically stretched therebetween.

Since the conventional height adjusting and folding table can fold the front covering plate, it is advantageous that the front covering plate can be easily folded and stored at the time of storage. However, there is a disadvantage accompanying the following problems.

First, the height adjusting and folding table must open both flanges 414a and 414b of the first fixing bar 412 in order to fold or unfold the front shielding plate 130, so that the second fixing bar 422 is strongly pulled or pushed out There is a disadvantage that it is very strong and inconvenient because it requires operation.

When the front cover plate 130 is repeatedly folded or unfolded, the height adjustment and folding table is deformed so that the flanges 414a and 414b on both sides of the first fixing bar 412 are permanently opened, There is a disadvantage that the unfolded state of the plate 130 can not be stably maintained.

In addition, when the height adjusting and folding table can perform an operation of repeatedly folding or unfolding the front shielding plate 130, the paint is peeled off from the contact portions of the first fixing bar 412 and the second fixing bar 422, Or the folding operation can not be stably performed due to the damage.
