The present invention relates to a director's chair, particularly a cross-elastic director's chair, which falls within the technical realm of director's chair.
Director's chair is a collapsible chair that is commonly referred to as a director's chair because of its regular utilization in film production sets. The primary components of a director's chair are frame and surface, and its foldability and portability make it a popular choice for outdoor sports and outdoor operations. Existing director's chairs are designed with fixed base feet, which restrict any rocking movement, thus leading to overall poor comfort. This invention presents a novel solution to tackle the aforementioned problems.
The present invention aims to overcome the deficiencies of existing art by introducing a new cross-elastic director's chair.
The objective of this invention can be accomplished by implementing the following technical solutions:
A cross-elastic director's chair comprising frame and elastic base feet; said elastic base feet comprise two sets of crossbar 1, crossbar 2, cross frame and elastic support arranged at the bottom of said frame. Said cross frame is movably installed between said crossbar 1 and said crossbar 2.
Preferably, said cross frame comprises a main connecting rod rotatably installed between said crossbar 1 and said crossbar 2.
Preferably, said main connecting rod is flanked by secondary connecting rod 1 and secondary connecting rod 2, which are pivotally mounted on said frame and said crossbar 1, respectively.
Preferably, said crossbar 1 comprises bar 1. The bottom of said bar 1 is fitted with mount 1 accommodating said main connecting rod. The interior of said mount 1 is furnished with mounting shaft 1 used to connect said main connecting rod.
Preferably, said crossbar 2 comprises bar 2. The top of said bar 2 is fitted with mount 2 accommodating said secondary connecting rod 1. The interior of said mount 2 is furnished with mounting shaft 3 used to connect said main connecting rod.
Preferably, said main connecting rod is provided with through-hole 1 that matches with said mounting shaft 1 and said mounting shaft 3.
Preferably, one side of said mount 1 is provided with mounting shaft 2 installed through bar 1, and that one side of said mount 2 is furnished with mounting shaft 4 installed through said bar 2.
Preferably, said secondary connecting rod 1 and said secondary connecting rod 2 are provided with through-hole 2 matching with said mounting shaft 2 and said mounting shaft 4.
Preferably, said elastic support is spring arranged between said crossbar 1 and said crossbar 2, and that the bottom end of said spring is securely attached to the top of said crossbar 2.
Preferably, said elastic support is curved elastic tube; one end of said elastic tube is connected to crossbar 3 while the other end of said elastic tube is connected to said frame.
Beneficial technological effect of the prevent invention: By incorporating crossbar 1, crossbar 2, cross frame, and elastic support, the cross-elastic director's chair of the present invention enables the support of the frame during use through the coordination of the cross frame and elastic support with crossbar 1 and crossbar 2. When a user is seated in the frame, the cross frame and the elastic support allow for a slight rocking motion of the frame, enhancing comfort while seated.

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.
As illustrated in
Cross frame 4 comprises main connecting rod 401 that is rotatably mounted between cross bar 12 and cross bar 23; on either side of main connecting rod 401 is secondary connecting rod 1402 arranged on frame 1 and secondary connecting rod 2403 arranged on crossbar 12; cross frame 4 is an X-shaped frame; when the chair is being used, main connecting rod 401, secondary connecting rod 1402, and secondary connecting rod 2403 ensure the strength of the connection between frame 1 and crossbar 12; additionally, the frame can deform depending on the deformation of frame 1 and crossbar 12.
Crossbar 12 comprises bar 1201; the bottom of bar 1201 is fitted with mount 1202 accommodating main connecting rod 401; mount 1202 internally accommodates mounting shaft 1203 for connecting main connecting rod 401; crossbar 3 comprises bar 2301; the top of bar 2301 is fitted with mount 2302 for installation of secondary connecting rod 1402; mount 2302 internally accommodates mounting shaft 3303 for connecting main connecting rod 401; main connecting rod 401 is designed with through-hole 1 that fits with mounting shaft 1203 and mounting shaft 3303. By setting up mount 1202 and mount 2302, main connecting rod 401 can be rotatably arranged between bar 1201 and bar 2301, in coordination with mounting shaft 1203, mounting shaft 3303, and through-hole 1.
On one side of mount 1202 is a mounting shaft 2204 that is installed through bar 1201; on one side of mount 2302 is a mounting shaft 4304 that is installed through bar 2301; secondary connecting rod 1402 and secondary connecting rod 2403 are provided with through-holes designed to fit and cooperate with mounting shaft 2204 and mounting shaft 4304. By setting up mounting shaft 2204 and mounting shaft 4304, secondary connecting rod 1402 and secondary connecting rod 2403 can be rotatably arranged on both sides of bar 1201 and bar 2301, through coordination with through-hole 2.
The elastic support is spring 5 arranged between crossbar 12 and said crossbar 23, and the bottom end of spring 5 is securely attached to the top of crossbar 23. Spring 5, when subjected to compression or tension from crossbar 12, will support crossbar 12 to rebound under its own elasticity.
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 12 and crossbar 23; in response, spring 5 provides support.
Positioned on the right side of cross frame 4, spring 5 is stretched by the user sitting in the director's chair through crossbar 12 and crossbar 23. In response, spring 5 exerts its own elastic force to pull back crossbar 12 and crossbar 23.
The elastic support is curved elastic tube 6; one end of elastic tube 6 is connected to crossbar 33 while the other end of elastic tube 6 is connected to frame 1; elastic tube 6 passes through a channel opened in crossbar 12 and is connected to crossbar 2 movably. Incorporated elastic tube 6 provides support and rebound between frame 1 and crossbar 23 through its inherent elasticity.
In this particular embodiment, as depicted in
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 12 and crossbar 23.
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.
