Description

The present invention belongs to the field of sports equipment and specifically relates to a spherical chair.

Many conventional spherical chairs have two parts, a sphere and a seat. In addition, the sheet is generally made of plastic and integrally molded or metal parts assembled with screws. For example, there is a spherical chair provided with a device for retaining a spherical body, which is disclosed in a patent document having a Chinese application number "2004202001.51.5". In this spherical chair, the metal-made stopper rod is fixed to the seat with a nut, so the structure is unstable, it becomes loose and easy to come off during use, it is necessary to tighten the nut well, Inconvenient. In addition, the structure of the seat is complicated, and it is inconvenient to attach and detach and transport.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a spherical chair having a stable structure and convenient for attachment and detachment and transportation.

The configuration of the present invention is as follows.
In a spherical chair including an elastic ball and a support frame, the support frame includes: a plurality of support tubes that are curved tubes having a curved portion; and a plurality of connection tubes that are curved tubes having a curved portion. The open end of the connecting pipe faces upward, the open end of the connecting pipe faces downward, and the angle formed by the plane where each support pipe is located and the plane where the adjacent connecting pipe is located is the same. A three-dimensional closed curve structure is formed so that the support pipe and the connection pipe are connected end-to-end so that the elastic ball is set in the closed curve structure and supported by the closed curve structure. Characterized spherical chair.
Further, both ends of the support pipe are inserted into both adjacent connection pipes, and the support pipe and the connection pipe are positioned and fixed by pins.
In addition, projecting pins perpendicular to the pipe axis are mounted on both ends of the support pipe, and pin holes perpendicular to the pipe axis are provided at corresponding positions on both ends of the connecting pipe.
In addition, a non-slip is mounted at the center of the bottom of each of the support tubes.
Furthermore, a cover is further provided, wherein the cover has a spherical bottom and covers the curved portion of the support tube.

According to the above configuration, a stable support frame mechanism is configured by assembling several curved tubes, so that the yoga ball can be stably supported, and it is convenient for attaching and detaching and transporting. When used together, the aesthetic effect is improved and the advantageous effects of preventing wear and dirt on the yoga ball are obtained.

It is a perspective view of a support frame. It is a schematic diagram of the structure of a support tube. It is a schematic diagram of the structure of a connection pipe.

DESCRIPTION OF SYMBOLS 1 Elastic ball 2 Support frame 3 Support tube 4 Connection tube

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
As shown in the drawings, the spherical chair includes an elastic ball 1 and a support frame 2. The elastic ball 1 is an inflatable yoga ball. The support frame includes four identical support tubes 3 and four identical connection tubes 4. Both the support pipe 3 and the connection pipe 4 are curved pipes. The support pipe 3 and the connection pipe 4 are connected in order with the open end of the support pipe 3 facing upward and the opening end of the connection pipe 4 facing downward. Both ends of the support tube 3 are inserted into both adjacent connection tubes. The support pipes 3 and the connection pipes 4 are connected end-to-end so that the plane formed by the support pipes 3 and the plane where the connection pipes 4 adjacent to the support pipes 3 are positioned are the same. Is formed. At both ends of the support tube 3, protruding pins 5 orthogonal to the tube axis are mounted, while at corresponding positions on both ends of the connection tube 4, pin holes 6 perpendicular to the tube axis are provided. The support pipe 3 and the connection pipe 4 are positioned and fixed by the protruding pin 5. The yoga ball 1 is set in a support frame 2 having a closed curve structure and is supported by the support frame 2. In the support frame 2 having the closed curve structure, the four support legs of the support frame 2 are respectively formed by the curved portions of the four support tubes 3, and the lower half of the sphere of the yoga ball 1 is formed by the curved portions of the four connection tubes 4. Supported from all sides.

In order to prevent slippage, a rubber-based non-slip 7 is mounted at the center of the bottom of each support tube 3. The non-slip 7 may be connected to the support tube 3 with a screw. A cover 8 may be placed on the surface of the spherical chair to prevent dust, slippage and wear. The cover 8 has a spherical bottom so as to cover the yoga ball, and has four legs extending downward so as to cover the curved portions of the four support tubes. The cover 8 may be provided with a beautiful pattern so as to improve aesthetics.

This spherical chair is used as follows. Fill the yoga ball 1 with air. The support pipe 3 and the connection pipe 4 are connected end-to-end to assemble to form the support frame 2. The support pipe 3 is inserted into the connection pipe 4, and the angle between the plane on which the support pipe 3 is located and the plane on which the connection pipe 4 is located is defined by a projecting pin 5 in the support pipe and a pin hole 6 in the connection pipe. Is guaranteed by its position. When the support pipe 3 is inserted into the connection pipe 4, the protruding pin 5 sinks into the support pipe 3,
When it reaches the position of the pin hole 6, it protrudes and can be positioned and fixed. When the yoga ball 1 is set in the support frame 2 and covered with the cover 8, the yoga ball 1 can be used.

When trying to disassemble to carry, yoga ball 1 can be folded and stored by removing cover 8 and bleeding air from yoga ball 1. When the protruding pin 5 in the support pipe 3 and the connection pipe 4 is pressed, the support pipe 3 can be pulled out of the connection pipe 4, and the support frame 2 is connected to the four support pipes 3 and the four connection pipes 4. Can be decomposed into The disassembled yoga spherical chair occupies a small space and is portable.
