New description: [New technical field] This creation is about the improvement of the structure of the table and chair. It aims to provide a table and chair with the use of the desktop to improve, especially the table position that can be changed according to the user's writing habits. Structural improvement. • [Previous Technology] • ^ Press, currently widely used in auditoriums, lecture halls, classrooms and performance venues, etc., usually with a table design, providing users with the need to copy, record or view materials, while In order to take into account the convenience of people's access and travel, most of the table is connected to the armrest of the chair with appropriate joints, which can be deployed or retracted to the side of the armrest according to the needs of use. For the purpose of application, the above is the basic structure currently used. However, in the conventional structure, the table is located at the right side of the chair, and there is no call for the right-handed (right-handed) or left-handed (left-handed) user. [New content] In view of this, this creation is to provide a chair with a tabletop improvement, especially the table chair structure improvement that can change the position of the table according to the user's writing habits, and its main purpose. In order to achieve the above, the table and chair structure of the present invention includes at least: a seat, a table and a pivoting member, the seat body and the back body extending from the side of the body M421849 c upward The table is provided with a bracket and a table top extending from the bracket, the bracket is pivotally connected to the back of the backing body, and the bracket is slightly L-shaped, and the bracket is tied to the backing body Extending in a horizontal direction, and then extending toward the front of the backrest body and connected to the table top, is disposed between the table bracket and the backing body, so that the bracket and the table top can pivot the 180-degree pivoting member 'Let the tabletop change position according to the user's needs (for example, it can be located on the left or right side of the seat) to increase its practicality. [Embodiment] The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the embodiments. As shown in the first figure, the structure of the table and chair structure, and the second figure, the structure of the table and chair structure, the table and chair structure 1 includes: a seat 10, a table 20 and a pivot. a connector; wherein: the seat 10 is provided with at least three support rods 11 (four support rods as shown in the embodiment) and a seat body 12 mounted on each support rod , There is a backing body 13 extending from the seat body 12 to the side. The table 20 is provided with a bracket 21 and a table top 22 extending from the bracket 21, the bracket 21 is end-to-end connected to the back of the backrest body 13, and the bracket 21 is provided with a first rod portion 211 and a second portion. The rod portion 212 is slightly L-shaped, and the first rod portion 211 extends in the horizontal direction of the backrest body 13 to the frame, and the second rod portion 212 extends toward the front of the backrest body 13 Connecting to the table top 22; wherein the length of the first rod portion 211 is slightly larger than one-half of the width of the backrest body 13, and the first rod portion 211 of the bracket is pivotally disposed on the backrest body 4 13 near the horizontal center position. The pivoting member is disposed between the table bracket and the backrest body. Please refer to the third figure as shown in the third figure. The pivoting member may be a pivot 30' and the first pole portion 211 of the bracket and the back The body 13 is further provided with a corresponding pivot hole 31 through which the pivot 30 can be worn.
