Problems solved by technology

[0010] The sit-stand combined chair realizes the conversion of sitting and standing by adjusting the telescopic mechanism to control the tilt of the chair surface 30 or restore the level, but the chair cannot be installed with a chair back, so that the user cannot lean on the back, which has certain limitations, and It is also difficult to meet the requirements of office standing in practical applications
[0011] U.S. Patent US5536067 provides a kind of seat, and this seat is respectively through three gas rods: the gas rod 46 that is connected with the middle part of the seat frame 32, the gas rod 52 that is connected with the middle part of the support rod 32 that supports the seat frame and 54 to achieve the transition between sitting and standing, the cost is high, and the air rods are exposed under the seat, which affects the appearance

Embodiment 1

[0107] Embodiment 1: first define the reference orientation of each part of the present invention, the present invention is when the seat is normally installed and used, the front of the seat is the front end and the front side, and the rear of the seat including the position of the seat back is the rear end, rear side.

[0108] This embodiment firstly provides a seat conversion mechanism, such as Figure 1-7 , as shown in 20-22, including:

[0109] Seat support assembly 1, said seat support assembly 1 includes lift air rod 2, and the lower end of lift air rod 2 is plugged with support foot 3 with roller 4 at the bottom.

[0110] The base 5 above the ground is supported by the seat support assembly 1, and the base 5 is plugged with the upper end of the lifting air rod 2, and the height of the base 5 from the ground can be controlled by the lifting air rod 2. In this embodiment The height is set to 360-550cm; 400cm is the suitable height for most people.

[0111] The slide r...

Embodiment 2

[0123] Embodiment 2: as Figure 8-19 , as shown in 20-22, the difference from Embodiment 1 is that the first seat 10 of this embodiment is a frame structure, and an avoidance space 20 is opened in the middle of the first seat 10; and the second seat 11 is selectively embedded To the avoidance space 20 and surrounded by the first seat 10 in the circumferential direction, the first seat 10 is hinged relative to the moving rail 7; a bracket 21 extending forward is fixedly arranged on the moving rail 7, and the second The seat 11 is connected to the bracket 21 , and the second seat 11 moves up and down with the moving rail 7 . The rear side of the first seat 10 is hinged with the bracket 21. When the second seat 11 is embedded in the avoidance space 20, the second seat 11 and the first seat 10 are on the same plane that is conducive to sitting flat, and the two are completed. The seat support 9. In the flat sitting state, the two fit together to form a flat seating surface, whic...

Embodiment 3

[0129] Embodiment 3: as Figure 25 As shown, the difference from Embodiment 1 is that the driving assembly 15 of the multipurpose seat adopts a motor 40, and the motor 40 is a linear motor, and the sliding block 42 provided on the sliding rail 41 of the motor 40 is connected to the moving rail 7 , the motor seat 43 is connected to the base 5, and the movement of the sliding block 42 is controlled by controlling the switch of the motor 40, thereby controlling the moving rail 7 to move up and down along the static rail 8.

[0130] In this embodiment, the motor 40 is used to control the lifting of the moving rail 7, the movement is smooth and reliable, and it can be conveniently controlled to stay in any desired position.

[0131] It is easy for those skilled in the art to think that the motor 40 can also be a push rod motor.

Abstract

The invention discloses a seat conversion mechanism and a multi-purpose seat. The seat conversion mechanism comprises a base, a slide rail assembly arranged on the base and provided with a movable rail and a fixed rail, and a seat support part divided into a first seat and a second seat; the second seat is configured to be connected with the movable rail and is always kept in a generally horizontal state; the first seat is hinged relative to the second seat; and the seat conversion mechanism further comprises a back support part and a connecting rod. The invention firstly provides the seat conversion mechanism which has two states including (1) a flat sitting state which is like a common seat and is used for people to sit for work, and (2) a standing posture state; the rear end of the first seat is lifted, the front end of the first seat is folded downwards to keep drooping, and at the moment, only the second seat has a state of supporting the hip of a human body; and a user can lean on or straddle the uppermost part of the seat in the standing state, so that the physiological health requirements of people are met. The invention further provides the multi-purpose seat, which is used in cooperation with the seat conversion mechanism and is convenient and rapid in sitting and standing conversion.

Description

technical field [0001] The invention relates to the field of seats, in particular to a seat conversion mechanism and a multipurpose seat. Background technique [0002] Seats are widely used in modern people's study and work. For most office chairs or study chairs, they only have the function of sitting; from a physiological point of view, if a person stands for a long time, his legs are overloaded and he is prone to fatigue.
