DETAILED DESCRIPTION

[0023] To enhance the clarity and specificity of the technical solution of the present invention for those skilled in the art, the following detailed description is given in conjunction with the embodiments and accompanying drawings. However, it should be understood that the embodiments of the present invention are not limited thereto.

[0024] As illustrated in FIGS. 1-6, a cross-elastic director's chair comprises frame 1 and elastic base feet. The elastic base feet comprise two sets of crossbar 1 2, crossbar 2 3, cross frame 4 and elastic support arranged at the bottom of frame 1. Cross frame 4 is movably installed between crossbar 1 2 and said crossbar 2 3. By incorporating crossbar 1 2, crossbar 2 3, cross frame 4, and elastic support 5, the present invention enables the support of frame 1 during use through the coordination of the cross frame 4 and elastic support 5 with crossbar 1 2 and crossbar 2 3. When a user is seated in the frame 1, the cross frame 4 and the elastic support allow for a slight rocking motion of frame 1, enhancing comfort while seated.

[0025] Cross frame 4 comprises main connecting rod 401 that is rotatably mounted between cross bar 1 2 and cross bar 2 3; on either side of main connecting rod 401 is secondary connecting rod 1 402 arranged on frame 1 and secondary connecting rod 2 403 arranged on crossbar 1 2; cross frame 4 is an X-shaped frame; when the chair is being used, main connecting rod 401, secondary connecting rod 1 402, and secondary connecting rod 2 403 ensure the strength of the connection between frame 1 and crossbar 1 2; additionally, the frame can deform depending on the deformation of frame 1 and crossbar 1 2.

[0026] Crossbar 1 2 comprises bar 1 201; the bottom of bar 1 201 is fitted with mount 1 202 accommodating main connecting rod 401; mount 1 202 internally accommodates mounting shaft 1 203 for connecting main connecting rod 401; crossbar 3 comprises bar 2 301; the top of bar 2 301 is fitted with mount 2 302 for installation of secondary connecting rod 1 402; mount 2 302 internally accommodates mounting shaft 3 303 for connecting main connecting rod 401; main connecting rod 401 is designed with through-hole 1 that fits with mounting shaft 1 203 and mounting shaft 3 303. By setting up mount 1 202 and mount 2 302, main connecting rod 401 can be rotatably arranged between bar 1 201 and bar 2 301, in coordination with mounting shaft 1 203, mounting shaft 3 303, and through-hole 1.

[0027] On one side of mount 1 202 is a mounting shaft 2 204 that is installed through bar 1 201; on one side of mount 2 302 is a mounting shaft 4 304 that is installed through bar 2 301; secondary connecting rod 1 402 and secondary connecting rod 2 403 are provided with through-holes designed to fit and cooperate with mounting shaft 2 204 and mounting shaft 4 304. By setting up mounting shaft 2 204 and mounting shaft 4 304, secondary connecting rod 1 402 and secondary connecting rod 2 403 can be rotatably arranged on both sides of bar 1 201 and bar 2 301, through coordination with through-hole 2.

[0028] The elastic support is spring 5 arranged between crossbar 1 2 and said crossbar 2 3, and the bottom end of spring 5 is securely attached to the top of crossbar 2 3. Spring 5, when subjected to compression or tension from crossbar 1 2, will support crossbar 1 2 to rebound under its own elasticity.

[0029] Located on the left side of cross frame 4, spring 5 is subjected to compression by the user sitting on the director's chair through crossbar 1 2 and crossbar 2 3; in response, spring 5 provides support.

[0030] Positioned on the right side of cross frame 4, spring 5 is stretched by the user sitting in the director's chair through crossbar 1 2 and crossbar 2 3. In response, spring 5 exerts its own elastic force to pull back crossbar 1 2 and crossbar 2 3.

[0031] The elastic support is curved elastic tube 6; one end of elastic tube 6 is connected to crossbar 3 3 while the other end of elastic tube 6 is connected to frame 1; elastic tube 6 passes through a channel opened in crossbar 1 2 and is connected to crossbar 2 movably. Incorporated elastic tube 6 provides support and rebound between frame 1 and crossbar 2 3 through its inherent elasticity.

[0032] In this particular embodiment, as depicted in FIGS. 1-6, the operational process of the cross-elastic director's chair presented is outlined as follows:

[0033] When sitting on frame 1 and leaning back, the user's body weight compresses the elastic support. As a result, the elastic support undergoes a buffered rebound due to its inherent elasticity. While frame 1 shakes, crossbar 4 deforms in response to the changes in distance between crossbar 1 2 and crossbar 2 3.

[0034] The aforementioned description is merely an additional embodiment of the present invention, and the scope of protection of the present invention is not limited thereto. Any skilled person in the field of this technology, within the scope disclosed in the present invention, can make equivalent substitutions or modifications based on the technical solution and concept of the present invention. All such substitutions or modifications are within the scope of protection of the present invention.
