This application is based upon and claims priority to Chinese Patent Application No. 202420043528.6, filed on Jan. 8, 2024, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the technical field of sofas, and in particular to a packaging-optimized detachable sofa.
Sofas are a common and essential type of seat for home life. At present, sofas on the market usually include an integrated backrest and seat body that are not detachable and have a large volume and weight, making them inconvenient to transport and load and resulting in high transportation costs.
Chinese patent application CN216059924U provides a leisure sofa with detachable sofa legs, and relates to the technical field of furniture. The leisure sofa includes a sofa body, support legs, and a connecting mechanism. The sofa body includes a seat plate and a backrest. The support legs are arranged below four corners at a bottom end of the seat plate and connected to the seat plate through the connecting mechanism. The connecting mechanism includes mounting boxes, fixing grooves, and fixing elements. The mounting boxes are provided at the four corners at the bottom end of the seat plate. The bottom ends of the mounting boxes are provided with the fixing grooves. The top ends of the support legs are provided with the fixing elements that are matched with the fixing grooves. One end of the mounting box is provided with a locking mechanism for fixing the fixing element. The fixing elements and the fixing grooves are matched to quickly disassemble the support legs, avoiding damage on the support legs caused by collision during transportation. However, the detachable design of the leisure sofa is limited to the connection between the sofa body and the support legs, but the sofa itself is not detachable, resulting in the need for a large space for transportation and the failure of volume minimization.
In view of the defects in the prior art, an objective of the present disclosure is to provide a packaging-optimized detachable sofa.
The packaging-optimized detachable sofa includes a backrest support, two armrest frames, two armrest connecting rods, a seat cushion frame, a footrest, and a folding mechanism, where the folding mechanism includes two link assemblies; the two link assemblies are respectively detachably provided at inner sides of the two armrest frames; and the two armrest frames are connected at front and rear ends thereof through the two armrest connecting rods;
Preferably, the backrest support is a U-shaped wooden board structure; and a front side of the backrest support is provided with multiple backrest webbings arranged in parallel; and
Preferably, an opening is provided at a bottom of the backrest skin; and the backrest support enters the backrest skin through the opening at the bottom of the backrest skin.
Preferably, a middle of the link assembly is provided with a seat cushion mounting crossbar and an armrest mounting crossbar; and the seat cushion mounting crossbar is located above the armrest mounting crossbar.
Preferably, the armrest frames each include a wooden frame structure and a wooden board structure located at an inner side of the wooden frame structure; the wooden frame structure and the wooden board structure form the accommodating space at an outer side of the armrest frame; and the accommodating space is matched with the folding mechanism in terms of size; and
Preferably, the seat cushion frame includes a spring layer, a connecting piece, a first seat cushion frame, and a second seat cushion frame; and the spring layer includes multiple springs arranged in parallel; and
Preferably, an outer side of the second seat cushion frame and the seat cushion mounting crossbar are provided with corresponding threaded holes; the second seat cushion frame is detachably connected to the seat cushion mounting crossbar through a second screw; and the second screw passes through the threaded hole of the seat cushion mounting crossbar and is threaded to the threaded hole of the second seat cushion frame; and
Preferably, two ends of the armrest connecting rod are detachably connected to bottoms of the wooden frame structures or wooden board structures of the two armrest frames through third screws; and
Preferably, the armrest connecting rods are matched with the accommodating spaces at the outer sides of the armrest frames in terms of size; and
Preferably, the other end of each of the link assemblies is detachably connected to the footrest through a second screw.
Compared with the prior art, the present disclosure has the following beneficial effects:
The present disclosure features a simple structure and convenient operation. The backrest, the armrests, and the seat cushion of the sofa are detachably connected to the folding mechanism, making the sofa body detachable. The armrests and the folding mechanism are stored together in the armrest skin, and the components are properly stored. The design achieves volume minimization, saves transportation space, and avoids damage of sofa components caused by collision during transportation.
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. The following embodiments will be conducive to further understanding of the present disclosure by a person of ordinary skill in the art, but does not limit the present disclosure in any form. It should be noted that several variations and improvements can also be made by a person of ordinary skill in the art without departing from the conception of the present disclosure. These variations and improvements shall fall within the protection scope of the present disclosure.
The present disclosure provides a packaging-optimized detachable sofa. The sofa includes a backrest, armrests, and a seat cushion, which are detachably connected to a folding mechanism, making the sofa body detachable and the components properly stored. The design achieves volume minimization, saves transportation space, and avoids damage of sofa components caused by collision during transportation.
In the present disclosure, as shown in
The seat cushion frame 3 is detachably provided at middle inner sides of the two link assemblies. The two link assemblies each include one end detachably connected to a bottom end of the backrest support 1 and the other end detachably connected to the footrest 4. As shown in
The packaging-optimized detachable sofa is provided with a storage state. When the packaging-optimized detachable sofa is in the storage state, the backrest support 1, the armrest frames 2, the seat cushion frame 3, and the footrest 4 are disassembled from the folding mechanism 5. The folding mechanism 5 each are placed in accommodating spaces covered by the armrest skins at sides of the armrest frames 2. The solution achieves reasonable storage and a detachable structure, greatly saving transportation space and reducing the risk of damage caused by collision during transportation.
This embodiment is a preferred embodiment of the above basic embodiment, and provides a packaging-optimized detachable sofa.
As shown in
This embodiment mainly relates to an improvement in the storage state of the packaging-optimized detachable sofa. As shown in
In the description of the present application, it needs to be understood the orientation or positional relationships indicated by terms, such as “up”, “down”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, and “outside”, are based on the orientation or positional relationship shown in the accompanying drawings, are merely for facilitating the description of the present application and simplifying the description, rather than indicating or implying that an apparatus or element referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore shall not be interpreted as limiting the present application.
The particular embodiments of the present disclosure are described as above. It should be understood that the present disclosure is not limited to the above specific embodiments. Those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present disclosure.
