FIGS. 3 to 5 are exploded perspective views illustrating a shock absorber of a functional stool table according to a preferred embodiment of the present invention. The shock absorber serves as a cylinder and a cylinder rod using a support shaft and a second housing.

The shock absorber 50 is interposed between the second housing 32 and the chair 1 according to another aspect of the present invention to completely absorb or control the amount of impact due to the up-and-down motion.

In order to achieve this, the buffering means 50 of the present invention fills oil and gas in the internal space of the second housing 32 to pressurize the oil and gas during rocking of the chair 1 to generate oil pressure and air pressure, The shock is absorbed.

The upper shock absorber 50 includes a support shaft 51 which vertically moves into the inner space of the second housing 32 and is fixed to the bottom surface of the second housing, A plurality of ball bearings 43 interposed in a space between the planar bearings and a cylinder inner skin 52 provided with a hollow portion so as to be slidable upward and downward from the upper portion of the second housing to receive the support shaft, And a cylinder shell 53 which is provided to be coupled with the chair and slid up and down from the upper portion of the second housing and has a hollow portion to accommodate the cylinder inner skin.

The upper support shaft 51 is provided with a support step 51a having a diameter that is able to cover the bottom surface of the second housing 32 and a support step 51a extending from the upper part of the support step and vertically installed in the inner space of the second housing A rod portion 51b and a pressing portion 51c which is formed on the end portion of the rod portion with an expanded diameter as compared with the rod portion and presses the oil and gas.

Particularly, the upper pressing portion 51c is formed with one or more through holes 51d to prevent the oil and gas from flowing up and down through the corresponding through holes, avoiding the region where the rod portion 51b is formed.

The ball bearings 43 in the buffering means 50 are disposed at least in a spaced relation to the inner space of the second housing 32 so that installation in the upward and downward movement range of the cylinder shell 53 It should be done.

The upper flat bearing 44 is installed at the upper end and the lower end of the second housing 32, like the rotation adjusting means 40, to prevent the flat friction between the parts when the chair and the second housing are rotated.

The upper cylinder inner skin 52 is disposed so as to be slidable upward and downward from the upper end of the second housing 32 and a hollow portion is further formed therein so that the rod portion 51b of the support shaft 51 and the pressing portion 51c To accept. The cylinder inner skin 52 in which the rod portion 51b and the pressurizing portion 51c are accommodated is filled with oil on the upper side and gas on the lower side with respect to the pressing portion.

The upper cylinder shell 53 is provided with a plate member for guiding the coupling of the chair 1 on the upper side thereof and has a shape having a cylindrical-shaped protruding portion formed on the lower side of the plate member. The upper cylinder shell 53 is arranged such that a cylindrical projection is slidable upward and downward from the upper end of the second housing 32 in a state where the chair is engaged and a ball bearing And the flat bearing are pierced so that they can be engaged with each other.

The shock absorber 50 having the above configuration is configured such that the shock and vibration generated when the user sits on the chair 1 are filled in the inner shell of the cylinder inner shell 53 and the cylinder inner skin 52, At this time, loads are generated in the oil and gas by the rod portion 51b and the pressing portion 51c accommodated in the inner wall of the cylinder, so that oil pressure and air pressure are formed, Thereby absorbing shock and vibration.

6 is a technique in which a step is formed in the inner diameter of the elastic body 42 and the first housing 31 provided in the rotation adjusting means 40 so that the step and the elastic body of the first housing are given a buffering force to the support by using the spring action .

The upper rotation adjusting means 40 may have a step 31a at the position corresponding to the upper end of the elastic body 42 in the inner diameter of the first housing 31 as described above so that a shock due to the load of the connecting rod 30, 10) were absorbed by the elastic body so that the buffering action was achieved.

As the rotation adjusting means 40 includes the buffering action, the rotation efficiency is maximized by blocking the shock, the abrasion, and the noise together with the stomach damping means 50 at least twice. As a result, the durability of the table is maintained for a long time Can be preserved.

10 to 11 show another embodiment of the functional stool table according to the present invention. The functional stool table includes a reinforcing support 21a welded to the bottom surface of the upper plate 10 while embracing the outer periphery of the first support 21, And the angle changing means 60 installed between the means 40. The rotation angle of the connecting rod 30 to which the chair 1 is coupled can be finely adjusted and the chair can be firmly fixed Position.

The angle changing means 60 includes an angle control member 61 provided on the upper end of the first housing 31 and having a plurality of teeth formed on the outer circumference thereof and a ring fixedly mountable on the inner diameter of the lower end of the reinforcing support 21a And an angle adjusting member 62 including at least one stopper 62a capable of engaging with the teeth of the angle control member at the inner periphery of the ring.

The angle changing means 60 having the above configuration is configured such that when the connecting rod 30 is rotated while pulling out the chair 1 from the table, the stopper (not shown) of the angle adjusting member 62 engaged with the empty space of the angle controlling member 61 62a are moved to another empty space of the angle control member and the position of the angle is fixed.

Here, it is preferable that the angle regulating member 62 and the stopper 62a are made of a very thin plate material and can move between the empty spaces by elasticity.

According to the present invention having the above-described configuration, not only can it be widely used in a table, a table, a desk, etc., but also vibration and noise are blocked due to the smooth rotation efficiency of the bearing.

In the functional stool table of the present invention, the second housing connected to the chair is provided with a buffer means filled with oil and gas, thereby absorbing the swinging motion of the chair generated when the user is seated.

In addition, the functional stool table according to the present invention has the effect of maximizing the usability because the chair can be independently rotated by the angle switching means provided in the first housing and the second housing and the chair can be freely arranged by the user.
