Description

Armrest base forward-moving reclining office chair

Technical Fields

The utility model relates to an armrest-type base forward-moving tiltable office chair, which belongs to the field of office furniture, and particularly relates to a novel office chair which is designed according to ergonomics and can simultaneously realize the forward movement of the base when the back of the chair is tilted.

Background technique

Generally, the existing office chairs with reclining design mainly connect the back of the chair to the base through a reclining adjuster, so as to realize reclining at a certain angle. This kind of tilting simply takes the connector as the axis, and the object of tilting is the back of the chair. Therefore, it can be said that the angle adjustment of the back of the chair is simply performed. Generally, for the adjustment of the reclining angle of this kind of chair back, many people are used to sitting on this kind of chair, leaning their back against the back of the chair, and then pressing the back of the chair back with force, so that the back of the chair is tilted backward, but If you are careful, you will notice that after reclining, the back does not stick to the original position of relying on the back of the chair, but moves slightly downward. In fact, there is a certain amount of sliding friction. Therefore, such a tilting manner is not the most ergonomic design.

Utility model content

The purpose of the utility model is to avoid the deficiencies of the prior art, and provide a new type of office chair which has a simple structure and can simultaneously realize the forward movement of the seat when the back of the chair is tilted.

The purpose of this utility model is achieved by the following measures. The forward-moving armrest-type base seat is pushed by the seat back, 7-type armrest support frame, fixed shaft, seat, chute, base, and half-moon-shaped seat. Composed of arms, movable wheels, armrests and springs, the upper top of the 7-type armrest support frame is connected to the middle of the chair back through a fixed shaft, the vertical direction of the 7-type armrest support frame is designed as a hollow tube to cover the armrest, and the bottom of the 7-type armrest support frame It is connected and fixed with the base. The back of the chair can be rotated with the fixed axis as the axis. The bottom of the back of the chair is connected to the rear end of the seat through the push arm of the half-moon seat and the movable wheel. The back of the chair, the push arm of the half-moon seat and the seat can be Rotation is realized by movable wheels, and a chute is provided under the seat seat, the chute is a slope design with a high front and a low rear, the seat is connected to the base through the chute, and the inside of the seat and the base are respectively connected to two ends of the spring.

The utility model has a simple structure, can simultaneously realize the forward movement of the seat when the back of the chair is tilted, and conforms to the ergonomic design.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

Among the figure: chair back 1, type 7 armrest support frame 2, fixed shaft 3, seat seat 4, chute 5, base 6, half-moon seat push arm 7, movable wheel 8, armrest 9, spring 10.

As shown in the accompanying drawing 1, the armrest type base of the utility model can move forward and tilt the office chair seat by the back 1, 7 type armrest support frame 2, fixed shaft 3, seat seat 4, chute 5, base 6, half moon Shaped seat push arm 7, movable wheel 8, armrest 9, spring 10 are formed, and the upper top of 7 type armrest support frame 2 connects the middle part of chair back 1 through fixed shaft 3, and the vertical direction of 7 type armrest support frame 2 is a hollow tube Designed so that the armrest 9 is caught, the bottom of the 7-type armrest support frame 2 is connected and fixed with the base 6, the seat back 1 can be rotated with the fixed axis 3 as the axis, and the bottom of the seat back 1 is connected with the movable wheel 8 through the half-moon seat push arm 7 The rear end of the seat 4, the seat back 1, the half-moon-shaped seat push arm 7 and the seat 4 can be rotated through the movable wheel 8, and the seat 4 is provided with a chute 5, and the chute is front high and rear Low slope design, the seat 4 is connected to the base 6 through the chute 5, and the inner sides of the seat 4 and the base 6 are respectively connected to two ends of the spring 10.

When the utility model works normally, the user first applies pressure to the back of the chair to tilt backwards. At this time, since the back of the chair can be fixed at a fixed axis as the axis to achieve a certain angle of tilting, the upper end of the back of the chair is tilted backwards, and at the same time The lower end of the seat back moves forward, when the lower end of the seat back moves forward, the half-moon-shaped seat push arm connected to the lower end of the seat back moves forward, and then pushes the seat forward along the chute until it moves to the end of the stroke , stop moving forward, and stop tilting at the same time, realizing the linkage between the tilting of the back of the chair and the forward movement of the seat, and vice versa, when the pressure of tilting back is stopped, the tension of the spring will push the seat back It is closer to the base, and at the same time, the chute is designed as a slope with a high front and a low back. Due to the pressure of the occupant's own weight, even if the seat moves backward along the backward slope of the chute, the seat is connected to the half moon. The push arm of the shaped seat will drive the push arm of the half-moon seat to move backward, and the push arm of the half-moon seat will push the back of the chair to move forward, stop leaning forward, and realize the control of the tilt angle.
