Description

Sofa and packing and transporting method thereof

Technical Field

The invention relates to the field of furniture, in particular to a sofa and a packaging and transporting method thereof.

Background

At present, most of sofas sold in the market are integrated, and the design meets the requirements of people on the sofas to a certain extent, but has some defects. For example, when the integrated sofa is disassembled and washed, more strength is needed, and the integrated sofa is easy to wash and is not clean; in addition, the sofa with the integrated design has the advantages of large volume, difficult transportation, high transportation cost, complex production and processing technology and high production cost. Nowadays, network sales are more and more developed, furniture can be sold to all over the world through network sales channels and can be delivered to various places in a logistics transportation mode, and the existing integrated sofa is large and inconvenient for logistics transportation; meanwhile, some online shopping malls also have requirements on the size of goods delivered, for example, amazon shopping malls have corresponding warehousing standards for the size, weight and package of warehoused goods, so that in order to meet the special requirements of network sales, sofas need to be split into a plurality of module assemblies and then transported. The soft package of sofa is the corollary articles for use of sofa, including cushion, sofa pad etc. at the in-process of sofa packing transportation, because the soft package of sofa has certain elasticity, leads to the operator to pack comparatively hard, and the soft package of sofa if not compress, and the volume is great, and the cost of transportation is higher.

In this embodiment, the seat frame 11, the back frame 51, and the armrest box 7 are all rigid frames made of wood or metal, and the rigid frames may be fixed-shape frames or frames with a shape that can deform to some extent. For example, the seat frame 11 may be a functional frame capable of tilting disclosed in patent documents such as CN110604408A and CN104799597A, or an iron frame having a movable leg rest, and the functional frame or the iron frame may be passively tilted or driven by an electric cylinder to tilt.

In a preferred embodiment, the rigid frame is wrapped with a layer of upholstery wrap for enhanced aesthetics. The lining cloth wrapping article can be made of cheap or wear-resistant cloth such as cotton cloth, non-woven fabric and the like. In order to make full use of the internal space of the rigid frames, the upholstery covers have an opening into which the seat cushion 15, the backrest cushion 3 or the arm rest cushion 2 can be inserted, which opening can be either always open or covered with a cover.

In this embodiment, the seat frame 11 has a functional frame capable of being tilted as shown in patent documents CN110604408A and CN104799597A, and the like, a connecting member a12 is provided on the functional frame, a leg rest plate 81 capable of being raised movably is provided on the front side of the functional frame, side plates are provided on the left and right sides of the functional frame, a seat plate is provided above the functional frame, and the seat plate is fixedly connected to the side plates on both sides. The connector a12 is a cone and the connector C54 is a cone sleeve that mates with the cone. When the sofa functional frame is driven by an electric cylinder or an air rod to lie down, the back frame 51 connected with the connecting piece A12 tilts backwards, and the leg placing plate 81 is lifted upwards. The connecting piece B13 is a T-shaped plug sleeve fixed on the left and right side plates of the seat frame 11, and the connecting piece D73 is a T-shaped plug fixed on the side plates of the armrest box 7.

The back cushion 3, the seat cushion 15 and the armrest cushion 2 comprise inner fillers and outer wrapping sleeves, the inner fillers can be elastic soft bodies such as sponge, cotton, down feather or artificial cotton, and the outer wrapping sleeves can be made of materials such as cloth, real leather, leather and reticular cloth.

In this embodiment, downwardly extending forms shirt rim 16 around the bottom of the outside parcel cover of cushion 15, and this shirt rim 16 cover is pasted A14, connector link or zip fastener and is realized dismantling the connection with the seat frame 11 curb plate through the magic on the seat frame 11, like this, realizes dismantling through shirt rim 16 between cushion 15 and the seat frame 11 and dismantle connection and location, easy dismounting and cushion 15 is difficult for removing. As shown in fig. 2 and 3, a leg rest board soft body 82 is installed at the front part of the outer wrapping sleeve of the seat cushion 15, the joint of the leg rest board soft body 82 and the outer wrapping sleeve of the seat cushion 15 is located at a position on the upper surface of the outer wrapping sleeve of the seat cushion 15 close to the middle of the seat cushion 15, the upper part of the leg rest board soft body 82 covers the front part of the outer wrapping sleeve of the seat cushion 15, the lower part of the leg rest board soft body 82 covers the leg rest board body 81, the bottom wrapping 83 of the leg rest board soft body 82 is wrapped to the inner side of the bottom edge of the leg rest board body 81 and is detachably connected with the leg rest board body 81 through a magic tape D84, a connecting buckle or a zipper, so that the leg rest board soft body 82 is convenient to disassemble and assemble, and when the leg rest board body 81 is lifted and retracted, the leg rest board soft body 82 is not pulled and influenced by. Similarly, in this embodiment, the leg rest board soft body 82 also includes an inner filler and an outer wrapping sleeve, the inner filler may be a soft body with elasticity such as sponge, cotton, down feather or artificial cotton, and the outer wrapping sleeve may be made of a material such as cloth, genuine leather, and mesh cloth. The leg rest board soft body 82 has less inner filler and is thinner as a whole. Like this with cushion 15 and leg rest board software 82 fixed connection as an organic whole, can reduce its whole volume through the mode of vacuum compression, make things convenient for the packing transportation, avoid outside wrapping up the cover and cause the damage, it can use to fluffy recovering again when the equipment.

In this embodiment, the back frame 51 is formed by fixing a front side plate, a rear side plate, and left and right side plates, the left and right side plates extend downward beyond the front side plate to form an opening at the lower portion of the back frame 51, and two connecting members C54 are respectively disposed on the inner side walls of the left and right side plates. Thus, when the sofa is assembled, the seat cushion 15 is positioned between the two connectors A12 to cover the inner sides of the connectors A12 and C54, and the left and right side plates of the back frame 51 cover the outer sides of the connectors A12 and C54 to prevent the connectors from being exposed to the outside and affecting the appearance.

In this embodiment, the external wrapping cover of the back frame 51 includes the back frame cover 52, the back cover cloth 53 of the back frame cover 52 extends downwards to cover the back side of the seat frame 11, and the bottom of the back cover cloth 53 is detachably connected with the seat frame 11 through a hook and loop fastener, a connecting buckle or a zipper.
