The rotary bar may have a ring-like groove shape that surrounds the rotary bar so as to be inclined with respect to a vertical plane of the rotary bar. The other side of the moving body is inserted, A guide groove formed at the lower end of the guide groove and having a height adjusted by the rotation of the support portion, and an engagement groove connected to the lowest position of the guide groove to receive a portion of the other end of the movement member, The other side of the moving body which is hooked to the engaging groove is moved to the guide groove to be unlocked as the rotating bar is turned to the left or right side by the user and when the user is raised from the rotating chair, The bar rotates and the other side of the moving body moves to the lowest position of the guide groove And a lock groove which is moved to be caught by the latching groove and fixed to the rotation bar, wherein the moving body is formed of any one of a sphere type, a rod type, and a bearing.

Further, the support portion is one of a fixed type that supports the rotation portion from the ground, or a movable type that supports the rotation portion from the ground and is movable in combination with a plurality of wheels.

With such a configuration, the automatic return type rotary chair of the present invention rotates through a portion of the rotary bar inserted into the fixed bar of the rotary bar, adjusts the height of the support portion, and seats the rotary chair. The rotation bar is rotated due to the inclination of the guide groove, so that the moving body is positioned at the lowest position of the guide groove, and the support body is returned to the original height and direction by engaging with the lock groove.

The automatic return type rotary chair of the present invention as described above has the following effects.

First, it is convenient to use and organize because it automatically returns to its original height and direction without having to use a hand separately for organizing at a branch office or a home, by the automatic return type by the guide groove and moving body configuration of the rotary bar.

Second, the time and cost required for manufacturing the lift mechanism by a simple structure formed by rotating the rotary bar and the fixed bar at the connected portion are reduced, and the assembly is not difficult and practical.

Third, since there is no height control section for raising and lowering, it is possible to prevent a child safety accident that may occur due to excessive raising and lowering repetition through the height control section, and a rotating bar that rotates substantially is inserted into the stationary bar, It is possible to prevent a jamming phenomenon.

Fourthly, since the conventional rotating chair was only capable of moving up and down, it was necessary to adjust the direction of the chair by holding and rotating the backrest every time when the used chair was arranged. Because of the characteristics of the rotating chair, it is possible to rotate the seat, However, in contrast to the case where the seat does not rotate in the adjusted direction, the automatic return type rotary chair of the present invention is a combination of the guide groove and the lock groove and the moving body so that the rotary bar rotates about the moving body, The lowest position of the guide groove is rotated by the moving body so that the moving body is caught in the locking groove so that the rotating chair can not rotate unless the user sits on the chair so that the height and direction of the receiving portion automatically return to the original position .

2 is a view showing the principle of lifting and lowering the rotary bar of the automatic return type rotary chair according to the embodiment of the present invention.
Fig. 3 is a view showing Fig. 3 of Patent Document 1. Fig.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings, and the inventor may appropriately design the concept of the term appropriately to describe its own design in the best way possible. It must be interpreted in terms of meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined.

Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

The rotation chair includes a support portion 40 for supporting a seat portion that supports the user's buttocks and a rotation portion for supporting the support portion 40 and for adjusting the height of the rotation seat by rotating the support portion 40, And a supporting portion for supporting from the ground.

At this time, the rotary part has a rotary bar 10 positioned at the upper end of the rotary part and one end fixed to the receiving part 40, a rotary bar 10 positioned at the lower end of the rotary part and having the other end of the rotary bar 10 inserted therein, And is fixed to the inner wall of the fixing bar 20 to guide the rotation of the rotary part. When the user rotates the rotary bar, the rotary bar 10 And returning the receiving portion 40 to the original position, i.e., the original position and direction.

As described above, the time and cost required for manufacturing the lift mechanism with a simple structure formed by rotating the rotary bar 10 and the fixed bar 20 are reduced, and assembly is not difficult and practical.

In addition, since there is no height control portion for ascending and descending, it is possible to prevent a child safety accident that may occur due to an excessive upward / downward repetition through the height control portion, and a rotating bar 10 which rotates substantially is inserted into the fixing bar 20 So that it is possible to prevent the finger or the like from being caught by the rotation.

Further, the movable body 30 is formed of any one of spherical, rod-shaped, or bearing, and the support portion is a stationary type that supports the rotary portion from the ground, or supports the rotary portion from the ground, It is one of the movable types that can move in combination.

FIG. 1 is a view showing an embodiment of a rotating bar 10 of an automatic return type rotating chair according to an embodiment of the present invention.

1, the rotating bar 10 of the automatic return type rotary chair includes a guide groove 11 and a lock groove 12. As shown in Fig.

The guide groove 11 is formed in an annular groove shape which surrounds the periphery of the rotary bar 10 obliquely with respect to the vertical plane of the rotary bar 10. The other side of the moving member 30 is inserted, The height adjusted due to the rotation of the receiving portion 40 is changed.

At this time, the inclination of the guide groove 11 is preferably 30 to 70, more preferably 40 to 55.

Here, when the inclination angle is less than 30 degrees, there is little difference in height adjustment, which is undesirable. When the inclination angle exceeds 70 degrees, the height change is excessively excessive, which is inconvenient for use.

The locking groove 12 is formed as a locking groove connected to the lowest position of the guide groove 11 so that the other side of the moving body 30 is caught.

The locking groove 12 serves to restrict rotation when the rotating chair is not in use to prevent damage to the surroundings due to unnecessary rotation.

Specifically, when the user sits on a rotating chair, the rotary bar 10 is turned to the left or right by the user, and the other side of the moving body 30, which is hooked to the lock groove 12, (11) and released.

The rotation bar 10 is rotated by the inclination of the guide groove 11 and the other side of the moving body 30 is moved to the lowest position of the guide groove 11 to be caught in the lock groove 12 The rotation of the rotary bar 10 is restricted.

The movable body 30 is moved to the lowest position along the guide groove 11 and is moved to and inserted into the latching groove to thereby fix the receiving portion 40. [

As described above, since the automatic return type according to the configuration of the guide groove 11 and the movable body 30 of the rotary bar 10 can automatically return to the original height and direction, This is convenient.

2 is a view showing the principle of lifting and lowering the rotating bar 10 of the automatic return type rotating chair according to the embodiment of the present invention.

2 (a) is a state in which the height of the receiving unit 40 is raised by the rotation of the rotating bar 10, (b) is a state in which the rotating bar 10 is automatically rotated and lowered (C) shows a state in which the movable body 30 is caught by the lock groove 12, and the rotation is restricted.

At this time, the height of the receiving portion 40 varies according to the position where the moving body 30 of the guide groove 11 is caught, and if the moving body 30 is not located in the locking groove 12, The rising and falling of the portion 40 can be continuously repeated at the same time as the rotation.

With such a configuration, the automatic return type rotary chair of the present invention is a non-powered system, and the rotating chair is lifted and lowered, so that the height can be manipulated without much effort.

Further, although not shown, the guide grooves 11 can be formed on the inner wall of the fixed bar 20 rather than the rotary bar 10, and the lock grooves 12 can be formed on the inner wall of the fixed bar 20 as shown in Figs. 1 and 2 Likewise, a sharp shape or a round shape can be used, but the moving body 30 can not be fully inserted, and the moving body 30 can be caught without rocking during the locking or unlocking process.

With this configuration, since the conventional rotary chair can be moved only up and down, the orientation of the chair has to be adjusted by holding and rotating the backrest every time the used chair is arranged. Because of the characteristics of the rotating chair, the seat can be rotated, The seat of the automatic return type of the present invention is formed by the combination of the guide groove 11 and the lock groove 12 and the moving body 30 as compared with the case where the seat is not rotated in the adjusted direction, The rotary bar 10 rotates about the movable body 30 along the inclination of the guide groove 11 so that the lowest position of the guide groove 11 comes to the movable body 30 and the movable body 30 30 so that the user can not rotate the chair so long as the user does not sit on the chair, and the height and direction of the receiving portion 40 automatically return to the original position.

As described above, although the present invention has been described with reference to specific embodiments and drawings, it is to be understood that the present invention is not limited thereto and that various changes and modifications may be made without departing from the spirit and scope of the present invention by those skilled in the art. It is to be understood that various modifications and changes may be made without departing from the scope of the appended claims.
