Description

Office leisure chair

Technical Field

The present invention relates to the field of chairs, and more particularly, it relates to office lounge chairs.

Background

Modern requirements for office chairs have not been limited to comfortable and healthy sitting, but also hope that office chairs will become a place to rest for a nap between work hours. Therefore, a plurality of products combining office chairs and leisure chairs are also available on the market. However, these office and leisure chairs usually have the backrest capable of being turned backwards to relax the waist and back of people, but neglect the legs and feet of people, so that the effect of relaxing the whole body cannot be really achieved.

Based on above-mentioned reason, prior art discloses back of the chair interlock formula official working leisure chaise longue in the chinese utility model patent that publication number is "CN 203000027U", including the cushion, install support, handrail and the chair foot that has the gyro wheel in the cushion bottom, the support on install elevating gear, the chair foot install the bottom of support, the handrail fix the both sides of cushion still include the back of the chair, interlock and callus on the sole, the back of the chair incline through the back of the chair incline the mechanism with the cushion connect, interlock include back of the chair support frame, first interlock and second interlock, back of the chair support frame first interlock the second interlock articulate in proper order, the callus on the sole install the end of second interlock. The beneficial effects of the scheme are as follows: the state of the office leisure chair is changed according to different postures of a human body, the comfort of relaxing and working of the human body is met through the telescopic foot pad and the chair back to the maximum degree, and the operation is simple. Above-mentioned current office leisure chair provides the callus on the sole and supplies to be used for carrying out the bracket when lying, but, this type of office leisure chair has some weak points:

1. the foot pad is linked with the chair back, or can be positioned only in the completely-stored and completely-extracted states of the foot pad; thus, such foot pads are not suitable for use by persons of different heights or leg lengths. When the foot pad is used by a user who is not completely suitable, the foot pad can only be in an active state and cannot be positioned, so that the unstable feeling cannot relax the whole body and mind of the user and influence rest;

2. the foot pad is exposed outside when being stored, which influences the beauty and the use.

Chinese patent No. CN208725230U discloses a sliding mechanism for opening a foot pad, which can be hidden in a seat when the chair is stored, but the sliding mechanism for the foot pad is complicated in structure and complicated in assembly.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides an office leisure chair, wherein a footrest adjusting mechanism of a footrest body is simple in structure, convenient and quick to assemble and is in non-linkage relation with a chair back.

In order to achieve the purpose, the invention provides the following technical scheme: an office leisure chair comprises chair legs, a chair seat and a chair back, wherein the chair seat and the chair back are arranged above the chair legs; a foot rest adjusting mechanism is arranged on the chair seat, and a foot pad body is arranged at the front end of the foot rest adjusting mechanism; the method is characterized in that: bracket adjustment mechanism is including fixing two at least telescopic links in the seat support, and the front end of telescopic link stretches into this internal and with callus on the sole body fixed connection of callus on the sole, and the telescopic link is stretched and is driven the callus on the sole body and expand or accomodate.
