Partitioned spring mattress and packaging method thereof

Abstract

The invention provides a foldable and rolled partitioned spring mattress which comprises a partitioned spring layer; the partitioned spring layer is provided with a first transverse area, a second transverse area and a third transverse area; the center line of the mattress penetrates through the second transverse area, the first transverse area is arranged between the second transverse area and the top of the mattress, the third transverse area is arranged between the second transverse area and the bottom of the mattress, and the second lateral region contains a bag spring with separate metal coils, each wrapped within a cloth bag. The first transverse area and the third transverse area comprise coils which are connected one by one through parallel spiral lines in rows, and the spiral lines extend in the direction perpendicular to the center line. After the mattress is compressed, the mattress is folded along the center line of the bag spring located in the second transverse area, then the compressed and folded mattress is rolled, and the spiral lines are not folded or bent. The packaging size of the partitioned spring mattress is smaller, and the partitioned spring mattress is more suitable for standard goods shelf spaces of express parcel transportation systems and retailers.

Description

technical field [0001] The invention relates to a mattress, in particular to a partition spring mattress. Background technique [0002] In the retail sales of mattresses, more and more sales are realized through online sales, and mattresses are delivered to online customers by express delivery. When foam mattresses began to be compressed, folded and rolled into sizes small enough to be handled through courier companies' logistics networks, online sales grew. Express companies use trucks for delivery, and drivers work independently. If it is a large-sized package, it cannot be transported by express. It needs to be transported by a freight forwarder. Each truck requires at least two people. For the low-priced mattresses that are usually sold online, the cost of mattress transportation is too high. [0003] The independent pocket spring (Pocket coil) in the spring mattress, also known as Marshall spring or pocket spring, the packaging method of this mattress can also be comp...

AI Technical Summary

Problems solved by technology

Mattress 14 cannot be folded or rolled about either longitudinal axis B because the helix 11 itself cannot be folded or rolled and if folded or rolled it will not spring back into a linear helix

For example, even though mattress 14 can be folded at its central transverse axis after compression, the folded mattress cannot then be rolled around a longitudinal axis perpendicular to helix 11

Therefore, the longest dimension of the package is still 60 inches, making the combined length and girth of the package exceed the maximum length, girth limit of some courier companies

Plus, the 60-inch length of the mattress package won't fit in the standard-height shelves of a major retailer

For a King size (W*L=76”*80”) mattress with interlocking springs, the longest dimension of the package after compression and rolling will be very long, so that the combined dimensions of the package’s length and girth will be Exceeds the length and girth limits of most couriers
