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

[0088] 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.

[0089] This embodiment first provides a seat unit, such as Figure 1-17 shown, including:

[0090] 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.

[0091] 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.

[0092] The slide rail assembly 6 vertically arran...

Embodiment 2

[0110] Embodiment 2: as Figure 23 As shown, the difference from Embodiment 1 is that in this embodiment, in addition to the lifting air rod 2 and the supporting feet 3, the seat support assembly 1 also includes a chassis 30 in order to make the user sit in a flat state more comfortably. Chassis 30 can adopt tiltable chassis, and this chassis 30 can be purchased from the market, and is not the inventive point of the present invention; In the present embodiment, described chassis 30 has seat body 31 and pallet 32, and pallet 32 ​​is connected On the upper end of the seat body 31 and rotate backward around the seat body 31 through the rotating shaft 39 , the upper and lower ends of the lifting air rod 2 are plugged with the seat body 31 and the supporting legs 3 respectively, and the base 5 is connected to the supporting plate 32 . Therefore, not only the initial height of the base 5 can be adjusted normally, but also the reclining function is provided when sitting flat, making ...

Embodiment 3

[0114] Embodiment 3: as Figure 25 As shown, the difference from Embodiment 1 is that the driving assembly 15 of the 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 with the moving rail 7, and the motor 40 is connected to the moving rail 7. The seat 43 is connected with 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 .

[0115] 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.

[0116] 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 chair unit and a chair. The chair unit comprises a base, a slide rail assembly, a seat support element, a back support element, a first connecting rod and a second connectingrod, wherein the slide rail assembly is vertically put on the base and is provided with a movable rail and a still rail; the seat support element comprises an outer seat and an inner seat; the innerseat is configured to always maintain an approximately horizontal state or a state of forming an acute angle with a horizontal plane; an avoiding space is formed in the outer seat; the inner seat is selectively embedded into the avoiding space to be surrounded by the outer seat; the outer seat is hinged relative to the movable rail; and the first connecting rod, the second connecting rod, the inner seat and the base form a four-connecting-rod mechanism. The invention firstly provides the chair unit capable of being freely converted between two states including a flat sitting posture state anda standing posture state, and the conversion can be realized only through sliding matching of the slide rail assembly. Compared with the prior art, the chair unit has the advantages that the structureis simple; the operation is very simple and convenient; and the cost is low. The invention further provides a chair which is matched with the chair unit to be used and has the advantages that the operation is simple and convenient, and the sitting and standing conversion is convenient and fast.

Description

technical field [0001] The invention relates to the field of seats, in particular to a seat unit and a seat. Background technique [0002] Seats are widely used in modern people's study and work.
