Ball chair improved structure

The invention relates to a ball chair structure, in particular to a ball chair improved structure which has quick assembly and has the same service life.

According to the advancement of manufacturing technology and the popularity of sports, the relevant industry and the creators of the case have successively developed the "Multi-function Rhythm Ball" No. 573542 and the certificate number M269929 "Multi-functional rhythm ball structure improvement". The patent case reveals a fitness rhythm ball product with a considerable size, and the patent case of the certificate number M250599 "ball seat with a ball anti-drop safety device" discloses a ball chair product with a large flexible sphere, among which, the certificate No. M250599 "A ball chair with a ball-proof anti-shedding safety device" patent case (please refer to the figures 7 and 8 at the same time), mainly to solve the problem that the ball chair may not be shaken or seated when riding. The ball is slid out of the seat, causing the user to fall, or even a dangerous accident; therefore, it is proposed to increase the stability of the ball of the ball chair, reduce the danger caused by the ball falling off, and can be transformed into a spherical shape. The ball chair of the sports equipment; the frame 30 is provided with a joint portion 32 on the top surface of the periphery of the through hole 31, and the positioning member 33 is provided to be assembled on the joint portion 32. Restrictions sphere 34, the sphere having doubts as to prevent slipping, falling at the time of travel, in order to increase their safety in use by the positioning member 33.

The details of the above-mentioned conventional structure are not difficult to detect, and the main reason is as follows: the joint portion 32 of the seat 30 is formed with a perforated shape, and the positioning member 33 is provided with a screw lock unit 331 corresponding to the joint portion 32. After passing through the joint portion 32, the lock is fixed by the nut 332, thereby The positional member 33 is stably assembled on the joint portion 32, but the inconvenience of structural assembly and assembly is also increased, and the ball 34 is also easily damaged by the sharp end of the screw lock unit 331 and friction, thereby reducing the service life of the ball chair without Practicality.

In addition, another type of ball chair structure on the market, please refer to FIG. 9 together, the ball chair 40 is integrally formed with a positioning member 41, so that the positioning member 41 cannot be removed by the ball chair 40, resulting in the overall volume of the ball chair 40. The increase, which in turn increases the packaging volume, significantly increases the packaging box and lacks environmental benefits, on the other hand increases the shipping costs and is not economically viable.

In view of this, the inventors have been engaged in the manufacturing development and design experience of related products for many years, and after detailed design and careful evaluation of the above objectives, the present invention has finally become practical.

The technical problem to be solved by the present invention is to provide a ball chair improved structure in view of the above-mentioned shortcomings existing in the prior art.

An improved structure of a ball chair, comprising: a seat and a limiting unit, wherein the seat has an arc-shaped receiving slot, and a joint portion is disposed on an inner side of the receiving slot, the joint portion At least two fastening holes are formed, and an opening-shaped fitting recess is formed on the joint portion. The limiting unit has an arc plate, and the engaging portion is provided with a latching protrusion at the joint portion, and the limiting unit is formed by an arc. The plate integral extending finite plate body is oppositely embedded in the fitting recessed portion, and the limiting plate body is protruded from the top end of the accommodating notch. With the above structure, the ball chair improved structure can be completed.

According to the effect of the prior art: (1), the seat of the seat is provided by the joint portion to provide the limitation unit, and the limitation of the sphere is achieved, and the assembly of the limit unit and the joint portion is fixed by the hooking method, and the assembly is fast. The effect of adding structural convenience, and also avoiding sharp objects such as the screw lock unit scratching and damaging the sphere, thereby improving the service life of the structural product. Practical.

(2) When the limiting unit is set in the seat, the arc plate is aligned with the inner wall of the receiving slot of the seat, thereby not only allowing the ball to be stable when the ball is placed in the receiving slot. It is attached to the inner wall of the accommodating notch, and can also use the ball to press the arc plate of the limiting unit, thereby effectively confining the limiting unit to the seat, greatly improving the structural stability between the seat and the ball, and adding sports use. Security.

(3) The limit unit and the seat frame are combined in a combination manner, so that when the structure is packaged, the structural volume can be greatly reduced by disassembly, thereby reducing the packaging volume to have environmental benefits, and the other convenience can also save transportation costs. To increase economic efficiency.
