Detailed implementation manners

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following is combined with the attached Figures 1 - 5The following will further describe the present utility model in detail with reference to the specific embodiments. The following embodiments are only examples for implementing the present utility model. It must be pointed out that the disclosed embodiments do not limit the scope of the present utility model. On the contrary, modifications and refinements made without departing from the scope of the present utility model fall within the scope of the patent protection of the present utility model.

[0025] A combined leisure chair includes a seat cushion 1 and an inner frame 5. The seat cushion 1 and the inner frame 5 are a combined structure of outer wrapping and filling molding. Vertical feet 2 are fixed to the end faces of each corner of the inner frame 5.

[0026] The vertical feet 2 are divided into two specifications, namely the front part and the rear part, according to the front-back distribution position. The front vertical feet 2 are of a ball-column structure, and the rear vertical feet 2 are of a column-bar structure. Moreover, the width spacing of the front vertical feet 2 is greater than that of the rear vertical feet 2.

[0027] A backrest plate 3 is arranged at the rear end of the inner frame 5, and back rods 10 are fixedly combined between the two ends of the backrest plate 3 and the inner frame 5.

[0028] A pair of fastening members 8 are symmetrically arranged on both sides of the rear end of the inner frame 5. An expansion shaft 12 axially extends from the fastening member 8. A side brace 9 is sleeved on the expansion shaft 12, and the side brace 9 is fixedly clamped with the back rod 10.

[0029] In the structure of this leisure chair, mainly the seat cushion 1 and the inner frame 5 structure formed by filling and combining are used to facilitate the external connection structure of the inner frame 5 while improving the sitting experience of the seat cushion 1 with the filling material. At the same time, compared with the traditional vertical foot support method, this leisure chair adjusts the vertical feet according to the sitting posture of the leisure chair through the front and rear vertical foot structures with relative differences. Its relative outward expansion and the support of the spherical column surface of the front vertical feet 2 can effectively improve the horizontal reverse stability of the seat surface, and at the same time avoid the problem of too hard sitting three-dimensional feeling caused by the perpendicular force direction before and after sitting in the vertical structure.

[0030] Considering the oblique support requirements of the backrest plate 3, the rear vertical feet 2 adopt relatively small spacing and vertical angles to provide effective support for the back rods 10 at the extension part of the backrest plate 3. Cooperating with the distribution of the front vertical feet 2, the stability and use experience of this leisure chair structure are improved.

[0031] As Figure 4 、 5 shown, the structure of this leisure chair further uses the fastening member 8 buckled between the inner frame 5 and the back rod 10 to utilize the expansion shaft 1 and the side brace 9 structures therein. Through lateral lapping, the connection structure between the back rod 10 and the inner frame 5 is further strengthened to serially combine the inner frame 5, the vertical feet 2, and the back rod 10, further improving the stability of this leisure chair.

[0032] Furthermore, a handrail 4 parallel to each other is provided between the inner frame 5 and the back rod 10, and a vertical rod 11 is inserted between one end of the handrail 4 relative to the back rod 10 and the inner frame 5. The extended handrail 4 structure forms a unified whole with the inner frame 5 through the erected vertical rod 11 to improve the integrity of the folding chair structure.

[0033] Furthermore, the fastening member 8 is a concave structure of a bottom buckle combination. The expansion shaft 12 passes through the fastening member 8 and the buckling end of the inner frame 5, and further fits and buckles with the edge of the inner frame 5 through the concave surface of the fastening member 8, and the connection strength between the inner frame 5 and the fastening member 8 is improved by means of the penetrated expansion shaft 12.

[0034] Furthermore, a shaft kit 13 is penetrated between the expansion shaft 12 and the fastening member 8, and the connection end of the expansion shaft 12 and the fastening member 8 is limited by the shaft kit 13 to fix the penetrated position of the expansion shaft 12 and improve the axial structure strength.

[0035] Furthermore, a toothed support ring 14 is sleeved on the side end face of the expansion shaft 12, and a damping ring is filled between the toothed support ring 14 and the side end face of the expansion shaft 12. The side face of the combined end of the expansion shaft 12 and the fastening member 8 is further limited and reinforced by the toothed support ring 14, and the filled damping ring provides damping support for the horizontal structure of the expansion shaft 12.

[0036] Furthermore, the side brace 9 is an L-shaped metal kit, and a holding member 15 is arranged on the side supporting surface of the side brace 9 and the back rod 10 in a matching manner. The fitting holding member 15 further increases the effective contact area between the side brace 9 and the back rod 10, that is, ensures the effective oblique direction support of the side brace 9 structure on the back rod 10.

[0037] Furthermore, an inner lining plate 6 and an outer lining plate 7 are respectively arranged at the front and rear ends of the inner frame 5, and the outer lining plate 7 overlaps with the outer end of the fastening member 8. The inner lining plate 6 and the outer lining plate 7 arranged inside and outside serve as the encapsulation surfaces of the inner frame 5 and the seat cushion 1, and the inner frame 5 is encapsulated by means of overlapping with the fastening member 8.
