Description

Torsion structure of the seat

The invention relates to a chair structure, in particular to a torsion structure of a seat which can improve the torsion smoothness.

According to the conventional swing chair structure, the structure shown in FIG. 16 is mainly composed of a base 60, a support rod 70 and a seat cushion 80, which is provided by the bottom leg 61. The support is positioned, and a sleeve portion 62 is erected at the center of the top side, and the end shaft 71 of the inclined support rod 70 is inserted and locked by the sleeve portion 62, and the sleeve 70 is provided with a sleeve at the other end. 72, the sleeve 72 is fitted with a rod portion 81 at the bottom of the seat cushion 80, so that the user can ride on the seat cushion 80 and apply the force to the seat cushion 80 to interlock the support rod 70, thereby providing the seat cushion 80 to rotate and The rotation of the bottom of the support rod 70 is the axis, but it is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reasons are as follows: (1) The rod portion 81 of the bottom surface of the seat cushion 80 is inserted. The sleeve 72 disposed on the support rod 70 causes the user's weight to concentrate on one point of the rod portion 81, and the weight is unbalanced, and there must be a gap between the rod portion 81 and the sleeve 72. The seat cushion 80 is easily inclined in one direction, so that the shaft portion 81 and the sleeve 72 are obliquely clamped, so that the seat cushion 80 is not easily pushed, and When the seat cushion 80 is initially pushed to rotate, the seat cushion 80 will generate a lateral thrust to the support rod 70, so that it is difficult to push the seat cushion 80 to perform a swing motion when stationary, and the above-mentioned use situation can be clearly understood. The conventional chair has not only the lack of smooth rotation, but also the possibility of inclined wear; (2) the rod portion 81 of the seat cushion 80 is inserted into the sleeve 72 in a straight tubular shape, and the support rod 70 The end shaft 71 is inserted into the sleeve portion 62 in a straight tubular shape. If the connection gap is too small, there is a problem that it is difficult to insert and assemble. If the connection gap is too large, there is a problem that it is easy to shake and loose. There is a lack of combined stability; (3) The axial area of the sleeve 72 is one tenth of the seating area of the small seat cushion 80, so that the user's weight is concentrated on a single point of the sleeve 72, and the sleeve portion The axial length of 62 is only six-sixth of the straight length of the support rod 70. First, the support rod 70 and the sleeve portion 62 cannot withstand a large lateral thrust, and sufficient balance support cannot be formed, so that the inclined deformation is easy to occur, and the torsion radius of the seat cushion 80 is larger than the sleeve 72. More than three times the diameter will further increase the oblique thrust generated when the seat cushion 80 is twisted, making the torsional action more laborious, resulting in relative oblique deformation between the seat cushion 80 and the support rod 70, thereby improving wear between each other. And reduce its torsion smoothness; the above is the technical problem that the creative is intended to solve.
