Abstract
According to the present invention, there is provided a rotary chair comprising: a support portion for supporting a seat portion that supports a user's buttocks; a rotation portion for supporting the support portion and adjusting the height of the rotation chair by rotating the support portion; The present invention relates to an automatic return type swivel chair including a support portion, wherein the conventional swivel chair requires a separate control portion and power for adjusting the height of the chair, and when the user wakes up from the chair, In order to solve the problem that the additional operation is required to adjust the height and the direction, it is very inconvenient and inefficient. In order to solve the problem, And returning to the height and direction of the automatic return type rotary chair .
Description
The present invention relates to an automatic return type rotary chair, and more particularly, to an automatic return type rotary chair that automatically returns to its home position, that is, its original height and direction when a user does not use the chair.
Conventional swivel chairs require a separate control unit and power to adjust the height of the chair and require extra work to adjust the height to the original height for the user to take care of when the chair wakes up and is very inconvenient and inefficient .
On the other hand, as a related art relating to a rotating chair, there is a Korean Registered Utility Model No. 20-0204775 (registered on September 18, 2000, guide sleeves of gas cylinders for adjusting the height of a rotating chair).
This Patent Document discloses a technique of "intervening between a
However, the conventional rotating chair such as the patent document can not solve the above-mentioned problems at all, and there is a problem that the time and material cost required for manufacturing the chair are wasted due to the complexity of the structure.
The present invention has been made in order to solve the above-described problems, and it is an object of the present invention to provide an apparatus and a method for adjusting a rotation angle of a rotary bar, And an automatic return type rotary chair which is returned to the direction of rotation.
It is another object of the present invention to provide an automatic return type rotating chair of a non-powered system not including a power source.
In order to achieve the above object, the automatic return type rotary chair according to the present invention is characterized in that, in the configuration of a rotating chair, a rotating chair has a support portion for supporting a seat portion that supports a user's buttocks, a support portion for supporting the support portion, And a support portion for supporting the rotation portion from the ground.
The rotary bar may include a rotary bar positioned at an upper end of the rotary part and having one end fixed to the support part, a stationary bar positioned at a lower end of the rotary part and inserted in the other end of the rotary bar, Wherein the rotary bar is positioned between the rotary bar and the fixed bar, and the rotary bar is positioned between the rotary bar and the fixed bar, one side of which is fixed to the inner wall of the fixed bar to induce the rotation of the rotary part, And automatically returns the height of the receiving portion to its original position and direction when it occurs.
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 .
