Description

Technical Field

[0001] The utility model relates to an improvement of an armrest structure of a seat, in particular to a lightweight armrest adapted to a swivel chair. Background Art

[0002] The armrest of a swivel chair is a side support structure for supporting the upper limbs of the human body. The armrest has a reliable support surface that can be used as a support surface other than a desktop to support the upper limbs. Therefore, it is suitable for use while working at a desk. The existing swivel chairs are relatively heavy in overall weight and all adopt relatively thick support surface structures, which will cause a stuffy feeling when used in summer. Thus, there has emerged a swivel chair structure with a mesh surface, which reduces the weight and provides comfort. In coordination with the lightweight of the chair, the armrest has also been correspondingly improved in terms of lightweight. Therefore, a lightweight armrest structure is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies existing in the prior art, and to provide a lightweight armrest adapted to a swivel chair.

[0004] The technical solution adopted by the utility model to solve the above problems is: The armrest includes a support frame and an armrest board. The bottom of the support frame is fixed to the bottom of the seat board. The support frame supports upward to form a vertical rod-shaped structure. The top of the support frame is fixedly connected with the armrest board. The upper surface of the armrest board is formed into a support surface, which supports the upper limbs. The armrest board is integrally formed into a flat support plate structure. The armrest board is formed with an arc-shaped handle, and the handle is bent downward based on the upper surface of the armrest board. The support frame is an upward upper limb support part based on the bottom of the seat board. The armrest board forms a support surface. The armrest board is a flat structure and is fixed to the support frame. The support structure is reliable. The armrest board also has a comfortable handle, which is convenient for getting up from the seat. The overall armrest board is simple and reliable, and the support is stable.

[0005] Further, the support frame has a fixed bottom plate, a support arm and a lifting seat. The fixed bottom plate is transversely arranged and fixed to the bottom of the seat board. The fixed bottom plate and the support arm are connected by an integrally extended arc-shaped body. The support arm is vertically arranged and integrally formed with a lifting seat at the top. The top of the lifting seat is fixedly connected with the armrest board. The lower surface of the fixed bottom plate is formed with weight-reducing empty grooves, and the weight-reducing empty grooves are formed with reinforcing ribs in a staggered manner. The fixed bottom plate is fixedly connected with the seat board. The support arm forms an upward lifting support structure. The lifting seat has a lifting support surface to support the armrest board. The whole is an integrally formed structure, and weight-reducing empty grooves are provided to reduce the structural weight, meeting the requirements of lightweight.

[0006] Further, the lifting seat is formed with a hollow structure from its top to the inside of the support arm. A vertical connecting column is formed on the lifting seat. The connecting column is connected to the armrest plate and fixed by inserting fixing nails. The inside of the support frame is arranged as a hollow structure, which reduces the usage amount of the overall material, optimizes the structural strength, and meets the requirement of lightweight design.

[0007] Further, the armrest plate includes an armrest panel and an armrest lower plate. The armrest panel and the armrest lower plate are fixed by snap-fitting. An installation groove is formed on the bottom surface of the armrest lower plate. The installation groove is arranged in alignment with the lifting seat. Screw holes are formed on the armrest lower plate. The screw holes correspond to the connecting columns and fixing nails are inserted through them. The armrest plate is structured as a top-bottom assembled structure, and the installation structure can be arranged between the two, keeping the external structure with a complete surface, improving the comfort of use. The provided installation groove and screw holes can facilitate alignment and improve the working efficiency of installation.

[0008] Further, the surface of the armrest panel is coated with a flexible material or formed into a skin-friendly surface. The flexible material can be wrapped on the armrest panel, and the edge of the flexible material is fixed after alignment. Additionally, the armrest panel can also be formed into a skin-friendly plastic material surface with a comfortable touch, which can prevent slipping and is more durable in use.

[0009] Compared with the prior art, the present utility model has the following advantages and effects: This design is an improvement in the armrest structure for the lightweight design of a swivel chair. The whole armrest is fixed to the basic structure of the seat. The armrest has good touch and support performance, provides good support function for the upper limbs, and improves the comfort of the seat. BRIEF DESCRIPTION OF THE DRAWINGS
