In general, various tables are manufactured in various sizes and shapes according to their use. Such a table is small and light in the case of a baby table, and a home or office desk is made large and heavy because of convenience in use.

In addition, lecture desks used in places such as lecture rooms and conference rooms are required to be lightweight and easy to move and store as compared with general household or business desks.

The conventional desk used in a classroom or a conference room usually has a structure in which the top plate can not be folded. Therefore, not only the table occupies a large area, but also requires a large space for storage and is not easy to move.

In order to solve such a problem, Korean Patent Registration No. 0774107 'folding table' (registered on Oct. 31, 2007) has been proposed.

Korean Patent Registration No. 10-0774107 " folding table " has a structure in which a latch mechanism for fixing a state in which the upper plate is unfolded is provided on both lower sides of the upper plate. It is essential that the upper plate is provided with two locking members, that is, the above-described latch mechanism, in order to stably fix the position of the upper plate when the size of the upper plate is large.

However, according to the above-described prior art, the conventional locking mechanism, that is, the latch mechanism, has a separate operation handle portion, and each of the lock mechanisms has to be unlocked by operating each lock mechanism. So that the user can not perform the folding work by himself.

The leg portion 200 includes a first leg connecting frame 212 connecting the first legs 211 separated from each other and the first legs 211 and having the first locking recess 110a formed on the inner side thereof, A second leg connecting frame 222 connecting the second legs 221 and the second legs 221 with the second locking legs formed on the inner side of the first leg leg 210, And a second leg portion 220 provided with the second leg portion 220.

The leg portion 200 may further include a rotation support frame 230 connecting the first leg portion 210 and the second leg portion 220. The top plate portion 100 may include a rotation support frame 230 As shown in Fig. A hinge member 130 is provided between the rotary support frame and the upper plate 100 to rotatably mount the upper plate 100 on the rotary support frame.

The folding table according to the present invention further includes a gas cylinder 140 rotatably coupled to a lower surface of the upper plate 100 and the rotary support frame to support the upper plate 100, When the upper plate 100 is lifted and rotated, the upper plate 140 is fixed to the upper plate 100 so that the upper plate 100 can be fixed in a raised state.

The rod portion of the gas cylinder 140 is rotatably mounted on the lower surface of the upper plate portion 100 and the cylinder portion of the gas cylinder 140 is rotatably mounted on the rotary support frame 230 .

The gas cylinder 140 is a known gas cylinder 140 in which a predetermined pressure of gas is filled in the cylinder.

Since the gas cylinder 140 helps the gas in the cylinder part to push up the gas cylinder 140, the upper plate 100 can be easily rotated, and the rotated upper plate 100 can be rotated So that the angle of rotation of the upper plate portion 100 can be fixed without rotating by the gas pressure of the upper plate portion 140.

The embodiment of the first locking member 10, the second locking member 20 and the locking connector 30 in the above embodiment is such that the locking member is attached to the upper plate portion 100, The second leg connecting frame 222 and the first leg connecting frame 212 are the same except that the first leg connecting frame 212 and the second leg connecting frame 222 are omitted.

That is, the first leg connecting frame 212 is disposed between the first locking supporting protrusion part 11b and the first locking latch part, and between the second locking supporting protrusion part 21b and the second locking latch part The first and second locking protrusions 12b and 22b are inserted into the first and second locking grooves 110a and 110b, respectively, The upper plate portion 100 is locked on the leg portion 200 in a state where the upper plate portion 100 is lifted.

When the first lock release lever member 13 is rotated to lift the upper plate 100, the first rotation link portion 13b pushes the first operation slope portion 12c to rotate the first lock projection 12b The first lock latch body 12a is pushed to move away from the first locking groove 110a of the first leg link frame 212. [

At this time, the first actuating connecting member 40 moves together with the first lock latch body 12a so that the first actuating projection 31a pushes one end side of the rotary actuating member 33, The operation member 33 is rotated, and the rotation operation member 33 is rotated to pull the second operation connection member 41.

The second actuating link member 41 is pulled and pulled out of the second lock latch body 22a so that the second locking protrusion 22b of the second leg connecting frame 222, The second lock latch body portion 22a is moved in a direction in which the second lock latch body portion 22a is released.

When the second lock release lever member 23 is rotated, the second rotation link portion 23b pushes the second operation slope portion 22c, so that the second engagement projection 22b is engaged with the second leg connection The second lock latch body portion 22a is pushed to move away from the second locking groove of the frame 222. [

At this time, the second actuating connection member 41 moves together with the second lock latch body 22a so that the second actuating projection 32a pushes one end side of the rotary actuating member 33, The operation member 33 is rotated and the first operation connection member 40 is pulled while the rotation operation member 33 is rotated.

The first actuating coupling member 40 is pulled and pulled out of the first lock latch body portion 12a so that the first locking concave groove 110a of the first leg connecting frame 212 is pulled out The first lock latch body portion 12a is moved in a direction in which the first lock latch body portion 12b is disengaged.

That is, when either one of the first lock release lever member 13 and the second lock release lever member 23 is rotated to release the locking state of either one of the first and second lock release lever members 23 and 23, The upper plate portion 100 can be lifted and folded.

The present invention can stably fix the position of the top plate 100 with two locking legs in the folding table to improve the stability in use and simultaneously release the two locking legs by a single operation so that the user can easily fold them alone, There is an effect of greatly improving.

As described above, an optimal embodiment has been disclosed in the drawings and specification. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention, The scope should be determined by the technical idea of the appended claims.
