This application is based upon and claims priority to Chinese Patent Application No. 202321024630.3, filed on Apr. 28, 2023, the entire contents of which are incorporated herein by reference.
The present disclosure specifically relates to a freely combined cube sofa and a combination sofa.
As a type of upholstered furniture, the sofa is an upholstered seat, formed with springs or thick foam paddings, and offers a backrest and armrests on two sides. There are various combinations of sofas, including single sofas, single couches, two-seat sofas, three-seat sofas, multi-seat sofas, corner sofas, and curved sofas. Combination sofas are loved by people due to their high flexibility and freedom of combination.
Chinese patent application CN106308198A provides a combination sofa, including a backrest, a sofa seat, and movable bases. A left side of a top surface of the sofa seat is provided with a rectangular groove. A protruding element of the backrest is provided in a fitted manner in the rectangular groove of the sofa seat. Four corners of a bottom surface of the sofa seat are provided with movable bases. The movable bases each include a hollow shell, a sliding frame, a pulley, and a step beam. An inner wall at a right side of the hollow shell is vertically provided with an L-shaped guide rail. A sliding element at a rear side of the sliding frame is provided in a fitted manner in a sliding groove. A right end of the sliding frame runs through and extends out of the inner wall at the right side of the hollow shell. A bottom surface at a left end of the sliding frame is vertically connected to two plates. A rotating shaft is vertically connected between the two plates. The pulley is rotationally provided on the rotating shaft. A bottom position of the hollow shell relative to the pulley is provided with a hole.
Due to the fixed structure, a sofa purchased by a customer is usually assembled by the manufacturer in the factory. After assembly, the sofa is transported as a whole to the customer's location. The sofa occupies a large space during transportation, greatly reducing transportation efficiency. Alternatively, the manufacturer may also send staff to the customer's location to assemble the sofa because assembly is quite difficult for the customer.
Therefore, it is necessary to provide a cube sofa that can be freely combined. Various components of the cube sofa can be disassembled and laid flat, making it easy to disassemble and assemble, reducing the packaging volume, increasing the loading capacity, and improving transportation efficiency.
In view of the defects in the prior art, an objective of the present disclosure is to provide a freely combined cube sofa and a combination sofa.
The present disclosure provides a freely combined cube sofa. The freely combined cube sofa includes: a seat cushion frame, a seat cushion, two armrest frames, a backrest frame, and a backrest cushion, where the backrest frame is detachably provided at a back of the seat cushion frame; the two armrest frames are respectively detachably provided at two sides of the seat cushion frame; the seat cushion is detachably provided on a top of the seat cushion frame; the backrest cushion is detachably provided at a front side of the backrest frame; the seat cushion frame is a detachable space frame; and outer surfaces of the seat cushion frame, the armrest frames, and the backrest frame each are covered with a detachable skin.
Preferably, the seat cushion frame includes a top frame, a bottom frame, and four connecting rods; and four corners of the top frame and four corners of the bottom frame are securely connected in one-to-one correspondence by the four connecting rods.
Preferably, the two sides of the seat cushion frame are provided with pins, and middles of the armrest frames are correspondingly provided with pin holes; the back of the seat cushion frame is provided with a pin, and a middle of the backrest frame is correspondingly provided with a pin hole; and the pin extends vertically upwards from the top of the seat cushion frame, and is inserted in a fitted manner into the pin hole.
Preferably, a bottom of the seat cushion is securely provided on the skin of the seat cushion frame through a Velcro; and a back of the backrest cushion is securely provided on the skin of the backrest frame through a Velcro.
Preferably, a bottom of the armrest frame is provided with a limit post; and the limit post includes a rubber limit post with an adjustable height.
Preferably, the skin is provided therein with a sponge.
Preferably, the seat cushion frame is provided therein with a seat cushion base plate.
Preferably, bottoms of the seat cushion frame, the armrest frame, and the backrest frame are located at a same height.
Preferably, four bottom corners of the seat cushion frame are securely provided with sofa legs.
The present disclosure provides a combination sofa, including multiple freely combined cube sofas, where multiple seat cushion frames fit together to form a combined seat cushion frame; and each two adjacent seat cushion frames are securely connected through a connecting piece; the combined seat cushion frame is strip-shaped, L-shaped, or C-shaped; and the combined seat cushion frame is correspondingly provided with one or more armrest frames, one or more backrest frames, one or more seat cushions, and one or more backrest cushions.
Compared with the prior art, the present disclosure has the following beneficial effects:
1. In the present disclosure, the sofa is composed of frames and cushions, which can be disassembled and laid flat. The seat cushion and the backrest cushion can be vacuumed and compressed to reduce the packaging volume and increase the loading capacity. The outer surface of the frame is covered with the skin, which is provided therein with the sponge to increase comfort and facilitate cleaning and maintenance. All the components have a unified specification, which facilitates replacement and maintenance, facilitates stable and unified quality control, and improves the efficiency of assembly, disassembly, and maintenance.
2. In the present disclosure, the seat cushion frame is a detachable space frame fixedly connected by the connecting rods, effectively reducing the packaging volume. The seat cushion frame is provided therein with the seat cushion base plate, and the seat cushion frame is provided with an internal chamber structure that can be used for storing items, improving space utilization.
3. In the present disclosure, the pin holes at a side of the armrest and a side of the backrest are fitted with the pins at a side of the seat cushion to achieve rapid disassembly and assembly.
Other features, objectives, and advantages of the present disclosure will become more apparent by reading the detailed description of non-limiting embodiments with reference to the following drawings.
The following describes the present disclosure in detail in conjunction with particular embodiments.
