Description

office lounge chair

technical field

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

Background technique

Modern people's demand for office chairs is not only limited to sitting comfortably and healthily, but also hopes that office chairs can be a place to rest between work. Therefore, there are also many products that combine office chairs and leisure chairs on the market. However, these office leisure chairs are often just the back of the chair that can be turned back to relax people's backs, but ignore the parts of people's legs and feet, so they can't really relax the whole body.

Based on the above reasons, the prior art such as the Chinese utility model patent with the publication number "CN203000027U" discloses a back-linked office leisure chair, which includes a seat cushion, a bracket installed at the bottom of the seat cushion, an armrest and a chair foot with rollers, so The lifting device is installed on the bracket, the chair foot is installed at the bottom of the bracket, the armrest is fixed on both sides of the seat cushion, and also includes a seat back, a linkage device and a foot pad. The seat back is connected with the seat cushion through a seat back tilting mechanism, and the linkage device includes a seat back support frame, a first linkage rod and a second linkage rod, the seat back support frame, the The first linkage rod and the second linkage rod are hinged in sequence, and the foot pad is installed at the end of the second linkage rod. The beneficial effects of the scheme are: changing the state of the office leisure chair according to the different postures of the human body, maximizing the comfort of the human body for relaxation and work through the retractable foot pad and the chair back, and the operation is simple. Although the above-mentioned existing office leisure chairs provide foot pads for footrest when lying down, such office leisure chairs have some shortcomings:

1. The foot pads are either linked with the back of the chair, or can only be positioned when the foot pads are fully retracted and fully withdrawn; thus, such foot pads cannot be used by people with different heights or leg lengths. If the above-mentioned users who are not fully applicable can only make the foot pads in an active state and cannot be positioned, this sense of instability cannot make the user relax and affect rest;

2. The foot pads are exposed on the outside when they are stored, which affects the appearance and use.

The Chinese patent with the authorization announcement number CN208725230U discloses a sliding mechanism for opening the foot pad. The foot pad on the chair can be hidden in the seat when it is stored. However, the structure of the sliding mechanism of the foot pad is relatively complicated. Assembly is cumbersome.

SUMMARY OF THE INVENTION

Aiming at the deficiencies of the prior art, the present invention provides an office leisure chair. The footrest adjusting mechanism of the foot pad body has a simple structure, is convenient and quick to assemble, and has a non-linked relationship with the chair back.

In order to achieve the above purpose, the present invention provides the following technical solutions: an office leisure chair, including a chair foot, a seat and a chair back arranged above the chair foot; The front end of the mechanism is provided with a foot pad body; it is characterized in that: the footrest adjustment mechanism includes at least two telescopic rods fixed in the seat, the front end of the telescopic rods extends into the foot pad body and is fixedly connected with the foot pad body, The telescopic rod expands and contracts and drives the foot pad body to unfold or store. The footrest adjusting mechanism of the foot pad body has a simple structure and is convenient and quick to assemble.

Preferably, a lumbar support is provided under the seat back, and the lumbar support protrudes forward relative to the seat back. When the back of the human body rests on the lumbar backrest, the lumbar backrest protrudes out of the chair back, so as to be closer to the waist of the human body, providing a support force for the waist of the human body, and greatly improving the comfort of the waist.
