Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing elderly chair sofas, in particular to a multifunctional elderly chair sofa with a simple base. Background Art

[0002] A multifunctional elderly chair refers to an elderly sofa with multiple functions. The most common elderly sofas are divided into two types. One is manually extended, and the manual function can also be equipped with shaking and rotating functions. Another is electrically extended, and the electric function can also have the two functions of shaking and rotating. According to current market demand, electric function frames are more common and popular among consumers. The base frame at the bottom of the electric function frame of the elderly chair is also particularly important. It is the main part that supports the entire electric function frame and plays a decisive role in the daily sitting and getting up of the middle-aged and elderly. To this end, we need to design innovations on the base of the elderly chair, that is, practical and low-cost to meet customer needs.

[0003] The utility model disclosed in application number CN201922021783.2 particularly relates to a base for an elderly chair. It includes two parallel side rods and a rear connecting rod and a front connecting rod connected to the front and rear ends of the two side rods in parallel, and mounting holes are provided on the rear connecting rod and the front connecting rod for the subsequent installation of the sofa seat; the two side rods are provided with an extended bending portion at the end of the front connecting rod, and the bending portion is formed by bending the end of the side rod, and the two ends of the rear connecting rod are provided with an extended portion, which is integrally formed with the rear connecting rod, and a side plate is fixed to the middle of each of the two side rods. The base of the elderly chair of the utility model has a widened portion on the base, which can increase stability, but the special shape of the bending portion requires a special mold, which is costly.

[0004] The utility model disclosed in application number CN201821701369.5 particularly relates to a rotatable sofa chassis. The sofa chassis includes an outer frame mounted on a supporting foot, a fixed mounting plate mounted inside the outer frame, a strip hole arranged along the length direction is opened in the middle of the fixed mounting plate; a rotating mounting plate is arranged above the fixed mounting plate, a connecting column is vertically arranged on the lower surface of the middle part of the rotating mounting plate, the connecting column passes through the strip hole downward and is connected to a lower limit seat, a swing arm is connected to one end of the rotating mounting plate, a connecting fulcrum passing through the fixed mounting plate downward is arranged on the lower surface of the middle section of the swing arm, a gas spring is installed on the lower surface of the fixed mounting plate, and the movable end of the gas spring is connected to the connecting fulcrum. Through the above-mentioned sofa chassis, the sofa cushion body mounted on the rotating mounting plate can be rotatable, although the sofa cushion body and the sofa back cushion present sofa shapes of different modeling proportions, and the operation of changing angles and shapes is simple and convenient, but this functionality is not suitable for elderly chair sofas.

[0005] The utility model disclosed in application number CN201920446547.2 refers in particular to a sofa bottom frame assembly, including at least one sofa bottom frame, the sofa bottom frame including two parallel mounting plates and at least two connectors, the mounting plates are symmetrically arranged on the left and right sides of the connector, at least one connecting plug is arranged on the outer side of the mounting plate, the two ends of the connector are respectively provided with connecting parts, the mounting plate is provided with mounting parts matching the connecting parts, the mounting parts can fix the connecting parts at different heights, and the connectors are used to adjust the height of the sofa feet. Although the height of the sofa feet and the depth of the sofa backrest can be adjusted in this utility model, and it is suitable for a variety of sofa sizes, the sofa bottom frame assembly is complex in structure, and the cost and labor cost are high under the premise of equivalent functions.
