Description

office lounge chair

technical field

The utility model relates to an office leisure chair.

Background technique

At present, the backrest of office chairs on the market can only be properly bent, and cannot achieve the effect of reclining. In addition, most of the current products do not have a support mechanism for the feet, and the comfort is not very ideal.

Contents of the invention

In order to overcome the disadvantage of poor reclining effect existing in existing office chairs, the utility model provides an office leisure chair which is easy to install, easy to use, takes up less space, and is suitable for office places.

The technical scheme that the utility model adopts is:

An office leisure chair, including a backrest, armrests, a seat plate, a footrest mechanism and a base, is characterized in that: the base is provided with a gas spring, the upper end of the gas spring is provided with a support plate, and the support plate There are inclined support rods on the left and right sides of the front end;

The seat plate is installed above the support plate, and the bottoms of the front and rear ends of the seat plate are respectively fixed with front support rods and rear end support rods, and the inclined support rods are connected with the front end support rods ; The two sides of the front end of the seat plate are provided with the footrest mechanism in parallel;

The armrest is arranged above the base, and the rear end of the armrest is hinged with the backrest;

The lower end of the backrest is connected to one end of a linkage mechanism through a connecting block, and the other end of the linkage mechanism is connected to the footrest mechanism.

Further, the linkage mechanism includes a slider, a guide rod, a first push rod and a second push rod, the top of the slider is fixedly connected to the connecting block, and the slider is arranged on the on the guide rod and can move forward and backward along the guide rod, the bottom end of the slider is connected with one end of the first push rod, and the other end of the first push rod is connected with the second push rod The middle part is connected, the two ends of the second push rod are respectively connected with the footrest mechanisms on both sides, and one end of the guide rod is fixed on the rear end support rod.

Further, the foot rest mechanism is a quadrilateral mechanism, and the quadrilateral mechanism includes a first rod, a second rod, a third rod and a fourth rod, and one end of the first rod is connected to the second push rod Hinged, the other end of the first rod is hinged in the middle of the second rod, the upper end of the second rod is hinged on the seat plate, and the lower end of the second rod is hinged with one end of the third rod , the other end of the third rod is hinged to the middle part of the fourth rod, and the upper end of the fourth rod is hinged to the front end support rod.

Further, it also includes an unlocker arranged on the backrest.

Working principle of the utility model:

Tilting of the backrest: After unlocking the backrest unlocker, the backrest can be tilted backwards with the help of human pressure, and then drive the slider to move forward on the guide rod, and the movement of the slider pushes the first push rod to move forward , the first push rod pushes the second push rod, causing the forward extension of the footrest mechanism, and finally reaches the limit position.

Lifting of the seat plate: when the slider moves forward on the guide rod, it will give an upward force to the guide rod. Since the guide rod is fixedly installed on the boss of the rear end support rod, the rear end support rod is welded to the seat plate together. In this way, the seat board can rise upwards under the action of the slide block.

The recovery process of the footrest mechanism: the user sits up and leaves the backrest first. At the same time, the user can use the legs to apply force to the footrest mechanism. The footrest mechanism is recovered, and the linkage mechanism is pushed, causing the slider to move backward. Return to the initial position.

Under normal conditions, the office leisure chair of the utility model does not open the backrest unlocker, the backrest will not tilt, and the footrest mechanism will not stretch forward, which is the same as a normal office chair. When the user needs to rest, the backrest unlocker is unlocked, and the person leans back hard, and the backrest will slowly topple over. Through the linkage mechanism in the middle, the footrest mechanism is pushed to move to a horizontal position to support the legs.

The beneficial effects of the utility model are embodied in: simple structure, more functions, convenient use and high cost performance.
