Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
Fig. 4 and 5 illustrate a specific coupling structure between the stool 3, the fixed frame 1 and the rotating frame 2. The rotating frame 2 is provided with a connecting hole I21 and a connecting hole II 22. In this case, a fixing member such as a pin is used as the rotation shaft 11 and the sliding shaft 12 to be coupled to the fixing frame 1 through the coupling hole one 21 and the coupling hole two 22. The rotating shaft 11 is installed at a high position, the sliding shaft 12 is installed at a low position, an arc-shaped sliding groove 13 is formed in the fixed frame 1, and the sliding shaft 12 can slide in the sliding groove 13.
An elastic member such as a spring may be integrated into the fixed frame 1, and the elastic member may be abutted against the rotating frame 2 to provide an elastic force required for returning when the rotating frame 2 rotates.
When the human body leans backward, the entire rotating frame 2 rotates relative to the fixed frame 1 about the rotating shaft 11. The sliding shaft 12 slides in the sliding slot 13, and the length of the sliding slot 13 provides a limit for the rotation angle of the rotating frame 2.
In the scheme, in order to further improve the comfort, the stool 3 is designed to be driven and rotated at a small angle. Two connecting pieces 33 are arranged in front of and behind the lower surface of the stool 3, a rotary front seat 14 is arranged on the fixed frame 1, a rotary rear seat 23 is arranged on the rotary frame 2, and the two connecting pieces 33 are respectively hinged with the rotary front seat 14 and the rotary rear seat 23. This allows the stool 3 to rotate by a small angle when the rotating frame 2 rotates.
As shown in fig. 1 and 2, the stool 3 is divided into an upper portion and a lower portion, the lower portion is a base 31, and the upper portion is a sliding plate 32, and the sliding plate 32 can slide in a front-rear direction, i.e., a left-right direction in fig. 2, with respect to the base 31. A plurality of guide grooves 34 extending in the front-rear direction are formed in the slide plate 32, and a positioning shaft 35 is fixed to the base 31, so that when a user slides the slide plate 32, the positioning shaft 35 slides in the guide grooves 34. The opening of the guide slot 34 not only defines the direction for the sliding direction of the slide plate 32, but also defines the maximum stroke of the sliding movement. The sliding design of the sliding plate 32 allows users of different sizes to obtain different extension lengths of the stools, further increasing comfort.
In the scheme, handrails 4 are respectively arranged on two sides of the rotating frame 2, and waist supports 5 are respectively arranged on two sides. The waist support 5 comprises a support body 51 for supporting the waist of a human body, and a rotating arm 52 is connected to the lower part of the support body 51. A driving member 54, which may be a gas spring, is installed on the lower surface of the stool 3, and its pushing-out direction is also the front-rear direction. The output position of the gas spring is connected with a pushing frame 53, the tail end of the pushing frame 53 is hinged with the rotating arm 52, and when the gas spring is pushed out and contracted, the pushing frame 53 moves forwards or backwards along with the gas spring, so that the rotating arm 52 is driven to rotate in the horizontal direction, and the support body 51 also rotates along with the gas spring.
The rotation of the support body 51 is to fit the waist of the human body in real time, and the output of the gas spring is uniform and stable, thereby improving the comfort of supporting the waist of the human body.
As shown in fig. 1, a headrest 8 is connected above the backrest 7, an adjusting bar 81 is provided at the lower portion of the headrest 8, the adjusting bar extends in the vertical direction, a plurality of positioning holes 82 are provided at different height positions, and the height of the headrest 8 is adjusted by connecting the adjusting bar with the different positioning holes 82 through a connecting member.
