Description

Technical Field

[0001] This utility model belongs to the field of sofa technology, and specifically relates to a wooden sofa. Background Technology

[0002] A sofa is a multi-seat chair with cushions. It has a backrest with springs or thick foam, and armrests on both sides; it is a type of upholstered furniture. Sofas can be classified by function into functional sofas, fixed-back sofas, infinitely adjustable sofas, pneumatic sofas, electric sofas, and sofas with built-in TVs. Sofas can also be classified by materials into four main categories: leather sofas, upholstered sofas, bentwood sofas, and rattan sofas.

[0003] A search revealed that Chinese patent CN208274421U discloses a multifunctional wooden sofa. Its structure includes a cover, placement holes, armrests, backrest, throw pillows, a base, a storage cabinet, seat cushions, a frame, and a moving device. The bottom of the cover is nested with the inner surface of the armrest; the placement holes are embedded in the inner side of the armrest; the back of the backrest is against the front surface of the backrest; the throw pillows are placed above the seat cushions; the bottom of the base is nested with the moving device; the top edge of the storage cabinet is against the inner upper surface of the frame; the moving device includes an outer shell, a brake plate, nuts, bolts, a support, and casters; the two sides of the outer shell are nested with the casters; the brake plate is interference-fitted with the outer shell; the outer surface of the bolt is connected to the nut via external threads; and the support and bolt are located on the same axis.

[0004] The aforementioned existing technology, by installing lockable casters at the bottom of the sofa, can basically meet the needs of moving and fixing the sofa. However, in actual use, it has been found that even after the casters are braked, the sofa still wobbles to some extent, resulting in poor stability. Moreover, the casters are mainly supported by axles, which can easily damage the axles when the sofa is occupied by multiple people. Furthermore, these casters are mainly installed at the bottom of the sofa legs through perforated wheel seats or studs with nuts, making it very inconvenient to disassemble and replace the casters later.
