Abstract
Description
- The present invention relates to the technical field of sofa accessories, and in particular, to an iron frame for a stand-assisting recliner and an operating method therefor.
- Recliners are essential furniture in many homes. With the continuous improvement of people's living standards, electric sofa recliners gradually enter ordinary people's homes. An electric sofa recliner is an electric sofa with an automatically adjustable backrest. The covering is usually made of high-quality genuine cowhide. The padding is high-grade sponge. The body structure is supported by a retractable recliner iron frame. The electric sofa recliner is fashionable and beautiful and is widely applied to homes, companies, among other places. Electric sofa recliners are a new chapter in the leisure industry and furniture industry. An electric sofa recliner can ingeniously integrate the practicability of furniture, the leisure aspect, and a high-tech, automated design.
- An existing iron frame for a recliner usually has a lying-flat position, a crossed-leg position, an upright sitting position, and the like. Many iron frames for a recliner, for example, those disclosed in Chinese Patent (Granted) Publications No.
CN202892335U , No.CN203538831U , and No.CN203314481U have the foregoing functions. The iron frames for a recliner disclosed in the foregoing patent documents do not have a stand-assisting function. It is very inconvenient for some elderly and disabled people to use such iron frames for a recliner. To overcome the foregoing disadvantages, Chinese Patent (Granted) Publication No.CN203986974U discloses a dual-motor drive mechanism for a recliner, including a base, a first drive head, a second drive head, a tail adjustment support assembly, and a middle adjustment support assembly being disposed on the base. The first drive head drives the tail adjustment support assembly to enable the tail adjustment support assembly to enter an erect state, a lying-flat state or an inclined state. The middle adjustment support assembly is correspondingly connected to a front adjustment linkage portion. The second drive head drives the middle adjustment support assembly to raise or lower to enable the middle adjustment support assembly to enter an erect state or a lying-flat state, and drives the front adjustment linkage portion to enable the front adjustment linkage portion to enter an unfolded state or a retracted state. In the retracted state, the front adjustment linkage portion is locked by the tail adjustment support assembly, and in the unfolded state, the front adjustment linkage portion is released by the tail adjustment support assembly. The dual-motor drive mechanism for a recliner can implement various functions of extending and retracting a recliner footrest, raising and lowering the recliner frame, tilting and erecting a backrest, and the like. Some special users need to lie on a recliner with the feet higher than the head to enable blood in the feet to quickly flow to the head or achieve other corresponding objectives. Existing recliner structures cannot implement the foregoing functions. - The technical problem to be resolved in the present invention is to provide an iron frame for a stand-assisting recliner that has a simple structure and can implement the function of keeping the feet higher than the head and an operating method therefor.
