A type of seating with foldable and expandable armrests

Abstract

This utility model belongs to the technical field of foldable and expandable armrest seating, specifically a foldable and expandable armrest seating system. It includes a sofa seat body with foldable armrest fabric fixedly installed on both sides. When space is limited and movement is inconvenient, the foldable armrests can be folded using a control zipper. Pulling the zipper opens the foldable armrest fabric. A user can then operate the control handles by pressing them with one hand, causing the handles to lower a sliding rod. The sliding rod moves a slider and several connecting rockers above it. These rockers move a folding and expanding swing arm around a rotating groove above a guide frame, allowing the swing arm to move a push plate. The push plate then pushes the expanding side panel, allowing the foldable armrest fabric to expand or contract.

Description

Technical Field

[0001] This utility model relates to the field of foldable and extendable armrest seating technology, and in particular to a seating with foldable and extendable armrests. Background Technology

[0002] Seating is an indispensable piece of furniture in homes, offices, and public spaces, with diverse usage scenarios and an increasing demand for spatial adaptability and functional practicality. However, traditional seating has many limitations, making it difficult to meet the needs of flexible use and space saving in modern life, which has become a key factor restricting the practicality of seating. Therefore, there is an urgent need to design a type of seating with foldable and expandable armrests. Traditional seating typically features fixed armrests that occupy space on both sides regardless of whether they are in use. In small apartments, compact offices, or temporary event spaces, fixed armrests result in a large overall footprint, making flexible placement difficult and even obstructing passage, leading to a waste of resources and space. Therefore, we have proposed a seating design with foldable and expandable armrests. During ocean container shipping, the folded armrests reduce the packaging size, increasing container capacity and significantly lowering product transportation costs. Utility Model Content

Felt is fixedly installed on the top inner wall and front inner side of the foldable and detachable armrest. The Velcro is attached to the felt. A control zipper is provided at the connection between the foldable and detachable armrest and the sofa seat body. The foldable and detachable armrest can be folded by controlling the zipper.

[0005] Preferably, two detachable backrests are fixedly installed on the back of the sofa seat body by Velcro, and flexible sponge is provided inside the detachable backrests, the sofa seat body and the foldable armrests.

[0006] Preferably, mounting partitions are fixedly installed on the left and right inner sides of the main body of the sofa seat, and a guide groove is provided on the top of the mounting partition. A slide rod is slidably installed on the inner side of the guide groove, and a control handle is fixedly installed on the top of the slide rod.

[0007] Preferably, two guide frames are fixedly installed at the bottom of the mounting partition. A rotating mounting groove is provided at the bottom of the guide frame. A folding extension swing arm is rotatably installed on the inner side of the rotating mounting groove. A push plate is fixedly installed on one side of the folding extension swing arm, and the push plate abuts against the main body of the sofa seat on one side.

[0008] Preferably, an extension side plate is also fixedly installed on one side of the push plate. The extension side plate is slidably installed on one side of the sofa seat body and is used to support the foldable and detachable armrests.

[0009] Preferably, a slider is fixedly installed at the bottom of the slide bar, and multiple connecting rockers are rotatably installed on the outside of the slider, with one end of each connecting rocker rotatably connected to the folding extended swing arm.

At this time, the operator can operate the control handles. The operator can press the control handles on both sides with one hand to lower the control handles, which in turn drive the slide bar to move. The slide bar can drive the slider and multiple connecting rockers above it to move. The connecting rockers can drive the folding and expanding swing arm to move around the rotating groove above the guide frame, allowing the folding and expanding swing arm to drive the push plate to swing. After the push plate moves, it can push the expanding side plate, which can expand or contract the position of the foldable armrest fabric. This utility model discloses a seat with foldable and expandable armrests. After adjustment, the control zipper can be pulled up and closed, and the foldable and detachable armrests can be placed back on top of the foldable armrest fabric. The expanded side panels can change the width of the foldable armrest fabric after movement, which facilitates the transportation of the main body of the sofa seat and prevents collisions with structures such as door frames during transportation. Moreover, the width of the foldable armrest fabric can be expanded, which greatly improves the comfort of the main body of the sofa seat. Attached Figure Description
