It will be described in detail by the drawings as follows.

The conversion part support (80, 810) is usually composed of the legs of the desk. When it is fastened to the legs of the desk, it is also possible to separately configure the converting part support next to the legs of the desk for convenience of work.

The switching units 40 and 400 configured in the switching unit supporters 80 and 810 are configured to raise and lower the chair. It is to raise and lower automatically or semi-automatically.

If the chair is pushed into the lower part of the desk, it will move to the upper part when there is a constant rotation.

Also, when the chair is pulled from the lower part of the desk to the outside of the desk, it moves to the lower part.

When the chair comes down to some extent, it comes down by the weight of the chair.

When the chair comes down to some extent, the force pushed by the gas spring stops working.

When the floor is cleaned in this way, the chair can be put on the top of the desk or moved to clean the floor, and then moved again to save the effort and time to move the chair and to use the narrow space efficiently.

It is configured on the upper and lower portions of the switching unit (40, 400) to configure the rotation unit (30, 300) configured to rotate with the switching unit support (80, 810). The rotating parts 30 and 300 are for rotating the connection support 200 connecting the chairs.

Of course, it is also possible to configure the rotating parts (30, 300) on one side of the switching parts (40, 400).

The connection bars 33 and 330 configured in the rotating parts 30 and 300 are connected to the connection support 200.

In order to connect to one end of the connection support 200, first to third holes 34, 35, 36, 332, 334, 336 are formed in the connection bars 33 and 330. The first holes 34 and 332 are coupled with one end 212 of the connection upper support, and the third holes 36 and 336 are connected with one end 222 of the connection lower support.

That is, one end portion 212 of the connection upper support, which is connected so as to be rotated with the connection bars 33 and 330, is connected to one end 222 of the connection lower support.

It constitutes a fixing part 500 connected to the other ends (214,224) of the connection support,

The fixing part 500 is connected to the chair support 710.

The fixing part may have the same shape as the connecting bars 33 and 330 of the rotating parts 30 and 300, and may have different configurations. Since rotation according to the movement of the chair is not required, it may be configured integrally with the chair support 710.

A 2-1 hole 134 is formed in the center of the direction changing rod unit 130 that is hinged with the second holes 35 and 334 formed in the connection bars 33 and 330.

One end portion 132 of the direction changing rod portion is inserted into the conversion grooves 42, 420 of the conversion portions 40, 400, and the conversion grooves 42, 420 when the connection support 200; 210, 220 rotates. Configure it to move along.

The other end portion 133 of the direction changing rod portion is coupled to the elastic portion 100, but the other end portion 110 of the elastic portion is hinged.

Therefore, when the direction changing rod part 130 and the elastic part 100 composed of the shock absorber form an angle, the pushing force acts greatly to push up the other direction of the elastic part on the connection upper support, and the chair attached thereto Is configured to move upwards.

When the elastic portion 100 composed of the direction changing rod unit 130 and the shock absorber is in a straight line, the additional force to be expanded is insufficient or configured to be insufficient so that the chair cannot be pushed upward.

Accordingly, the degree of elasticity of the elastic portion is appropriately determined.

The sixth hole 139 formed in the one end 120 of the elastic part is pin-coupled so as to be rotated by the fifth hole 217 and the fifth pin part 219 which are pinholes in the upper part of the connection upper support 210.

Where the fifth hole 217 is formed on the upper support is determined by the length of the force and the rising force.

The connection support 200 is composed of a connection upper support 210 and a connection lower support 220,

One end 120 of the elastic part 100 is hinge-coupled with the connection upper support 210 of the connection support 200 so that one end 132 of the direction changeable rod part is formed into the conversion grooves 42 and 420 While moving, it constitutes a chair elevating device for elevating the chair support 710 due to the elasticity of the elastic portion 100.

The conversion grooves 42 and 420 are composed of a horizontal groove 422 and an inclined groove 424, and when the one end 132 of the direction change rod part passes through the horizontal groove 422, the chair support 710 When the lifting of the inclined groove 424 is stopped and the inclined groove 424 is called, the lifting and descending of the chair support 710 is made.

When passing through the horizontal groove part 422, the gas spring 100 and the direction change rod part 130, which are the elastic parts 100, are configured to be generally horizontal, so that the fifth pin part configured by pin coupling to the connection upper support 210 ( 219) was configured so that no force was applied to it so that the chair was not moved upward.

The connection lower support 220 is configured to be inserted into the side portion of the connection upper support 210.

This configuration can prevent dust or foreign substances from being inserted into the connection support.

Even if it is configured in the form of a simple bar, the chair rotates, so there is no problem with the movement of the upper and lower parts.

A first hole (34, 332) is formed in the upper portion of the connection bar (33, 330) and is configured to rotate by combining one end of the connection upper support (210) with a first pin (932),

A second hole (35, 334) is formed in the middle portion of the connection bar (33, 330) so that it is coupled to the second hole (134) and the second pin (934) of the central portion of the direction change rod to rotate. Constituting,

Third holes 36 and 336 are formed in the lower portions of the connection bars 33 and 330, and are coupled to one end of the connection lower support 220 and the third pin 936 to rotate.

The connection upper support 210 and one end portions 212 and 222 of the connection lower support 220 and the other ends 214 and 224 of the connection upper support 210 and the connection lower support 220 each constitute a hole.

The fixing part 500 has a configuration corresponding to the connection bars 33 and 330, but is configured to fix the chair support 710 through a configuration corresponding to the connection bars 33 and 330.

It is okay to just configure pinholes in the upper and lower portions without having a corresponding configuration.

The cover part 600 is formed in the rotating parts 30 and 300 and the fixing part 500 to prevent dust or foreign matter from being inserted.

For the rotating part to rotate around the switching part support, a normal bearing may be used, or a material with little wear during rotation may be used.

6A to 6D are views showing the second embodiment.

1A to 5 are views showing the first embodiment.

The difference between the second embodiment and the first embodiment is that the connecting bar 33, the upper rotating part 31, and the lower rotating part 32 are separated from each other.

Fig. 6A is an overall view of the second embodiment.

The configuration diagram of the conversion part is an overall configuration diagram showing the minimum configuration that can function.

Fig. 6b is a view showing a switching unit 40 and a rotating unit 30 (a configuration including an upper rotating unit, a lower rotating unit, and a connecting bar) different from the first embodiment.

The switching part shows a configuration equivalent to 1/2 of the configuration of the first embodiment. The remaining 1/2 part is made of an appropriate cover configuration to maintain aesthetics.
