Description

Technical Field

[0001] The invention relates to the technical field of mattresses, and in particular to a partitioned spring mattress and a packaging method thereof. Background Art

[0002] An increasing share of retail mattress sales is being made online, with mattresses delivered to online customers by courier. Online sales grew when foam mattresses began to be compressed, folded and rolled into a size small enough to be handled by courier companies’ logistics networks. Couriers use trucks for delivery, and drivers work independently. Large packages cannot be shipped by courier and need to be shipped by freight forwarding companies, which require at least two people per truck, making the shipping cost too high for the low-priced mattresses that are typically sold online.

[0003] The pocket coil in a spring mattress is also called a Marshall spring or pocket spring. The packaging method of this mattress has been developed so that it can be compressed, folded and rolled. Therefore, compressed foam mattresses and compressed pocket coil mattresses are often sold online.

[0004] However, there are some types of spring mattresses that are not folded and rolled in any direction and are not usually sold online. For the larger Queen and King sizes of American mattresses, the combined length and circumference of the mattress after compression and rolling (unfolded) still exceeds the maximum size accepted by the courier. In addition, for these larger Queen and King sizes that cannot be folded and rolled in any direction, their packaging cartons cannot fit into the standard shelf space of large retailers, which are often the most popular sales channels for low-priced mattresses. Unlike pocket springs, these spring mattresses that cannot be folded and rolled in any direction have connected coils, which are connected in rows through parallel spiral wires to form a whole network of springs. Two common connected coils are Bonnell springs and continuous springs.

[0005] Figure 1 (Prior Art) shows the spring structure of a Bonnier spring. The Bonnier spring has individual hourglass-shaped spring coils 10 connected together by a helical wire 11. The helical wire 11 supports and connects each individual spring coil, usually arranged in rows laterally along the lower and upper sides of the spring coil. The spring structure also has a thick steel edge rod 12 forming a frame on the lower and upper sides of the spring. The steel edge rod 12 can also be eliminated, and when the mattress needs to be rolled and packaged for online sales, the steel edge rod 12 may not be required.

[0006] Figure 2 (Prior Art) shows two spring structures using wire-drawn springs, which use a steel wire woven into a mesh structure. Therefore, the wire-drawn spring does not have separate independent spring coils. However, the spring coils of the wire-drawn spring are also connected by a spiral wire 13 arranged in a horizontal row, and the spiral wire 13 is arranged along the top and bottom of the spring structure. Similarly, the steel wire edge rod 12 in the figure can also be eliminated. When the mattress needs to be rolled and packaged for online sales, the steel wire edge rod 12 may not be required.

[0007] Figure 3 (Prior Art) shows a mattress 14 having a Bonnier spring 15, wherein the individual Bonnier spring coils are connected one by one by parallel transversely arranged spiral wires 11. The mattress 14 also includes a thin foam layer 16 placed above the upper surface of the Bonnier spring 15. A mattress cover 17 encases the spring 15 and the foam layer 16. In this example, the mattress 14 is a Queen size mattress having a length of 80 inches and a width of 60 inches. Figure 3 The mattress 14 is shown to be able to be folded or rolled around any transverse axis A, while the spiral 11 itself is not folded or rolled. If the mattress 14 is compressed and rolled up from the bottom to the top, a 60-inch long mattress roll can keep each spiral 11 in a linear spiral shape. The mattress 14 cannot be folded or rolled around any longitudinal axis B because the spiral 11 itself cannot be folded or rolled, and if folded or rolled, it cannot rebound to a linear spiral after unfolding. For example, even if the 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 the spiral 11. Therefore, the longest dimension of the package is still 60 inches, so that the combined dimensions of the length and girth of the package exceed the maximum length and girth restrictions of some express companies. In addition, a 60-inch long mattress package cannot fit into the standard height shelves of large retailers. For a King size (W*L=76"*80") mattress with attached springs, the longest dimension of the package after compression and rolling will be very long, so that the combined length and girth of the package will exceed the length and girth restrictions of most express companies.

[0008] In addition, pocket springs are generally more expensive than linked springs, so a mattress and mattress packaging method that is lower in cost and smaller in package size, suitable for express parcel shipping systems and suitable for loading onto standard shelves of large retailers is sought. Summary of the invention

[0052] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0053] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0054] The transverse direction in the present invention is along the width direction of the mattress, the longitudinal direction is along the length direction of the mattress, and the center line is a line extending along the transverse direction of the mattress that can divide the mattress into two halves. The center line does not exist physically in the mattress.

[0055] Embodiment 1

[0056] like Figure 4As shown, a partitioned spring mattress of the first embodiment of the present invention comprises a partitioned spring layer 20, and the spring layer 20 comprises at least a first transverse zone 21, a second transverse zone 22 and a third transverse zone 23 arranged adjacent to each other in sequence. The second transverse zone 22 is located between the first transverse zone 21 and the third transverse zone 23. The second transverse zone 22 comprises a spiral wire and a coil, and the spiral wire extends longitudinally along the mattress and connects the adjacent coils in the second transverse zone one by one. The coil is a wire drawing spring or a Bonnier spring, and it has no separate, independent spring coils. The elasticity of the spiral wire is not as good as that of the coil. If it is folded or bent beyond a certain angle, the spiral wire cannot return to its original shape. In other embodiments, the spiral wire can also be replaced by a connecting steel wire of other similar structures that connects adjacent coils and cannot be folded or wound by itself. The first transverse zone 21 and the third transverse zone 23 each comprise independent coils wrapped in independent cloth bags, that is, the first transverse zone 21 and the third transverse zone 23 comprise pocket springs. The mattress has a first folding line 24 and a second folding line 25 extending in the transverse direction of the mattress. The first folding line 24 and the second folding line 25 pass through the first transverse zone 21 and the third transverse zone 23 respectively, so that the upper part of the spring layer 20 can be folded toward the second transverse zone 22 along the first folding line 24, and the lower part of the spring layer 20 can be folded toward the second transverse zone 22 along the second folding line 25. The lower part of the spring layer 20 and the upper part of the spring layer 20 can be stacked on the second transverse zone 22, or the lower part of the spring layer 20 and the upper part of the spring layer 20 can be folded on two opposite surfaces of the second transverse zone respectively, so that after folding, a three-layer mattress stacked on each other is formed.

[0057] The mattress has a centerline 26 extending in the transverse direction of the mattress, and the centerline 26 passes through the second transverse region 22. The distance between the second fold line 25 and the centerline 26 is approximately equal to the distance between the first fold line 24 and the centerline 26. The centerline of the second transverse region 22 coincides with the centerline 26 of the mattress. The distance between the first fold line 24 and the top of the mattress, the distance between the first fold line 24 and the second fold line 25, and the distance between the second fold line 25 and the bottom of the mattress are approximately equal, forming a tri-fold mattress.

[0058] The wire diameter of the independent coil in the first transverse zone 21 is smaller than that of the coil in the second transverse zone 22; the wire diameter of the independent coil in the third transverse zone 23 is smaller than that of the coil in the second transverse zone 22. When the wire diameter of the pocket spring is smaller than that of the brushed wire spring or the Bonnier spring, the support capacity of the pocket spring is still better than that of the brushed wire spring or the Bonnier spring, so it can provide better support to the user.

[0059] A partitioned spring mattress of the present embodiment adopts a segmented structure for the spring layer of the mattress, wherein the first and tail sections adopt pocket springs, and the middle section adopts ordinary springs such as brushed springs or Bonnier springs. The ordinary springs and the pocket springs are connected by a connecting piece, the center line 26 of the mattress passes through the ordinary springs, and the first folding line 24 and the second folding line 25 pass through the pocket springs. The spiral line of the ordinary spring is arranged along the length direction of the mattress, that is, it extends longitudinally along the mattress, and the pocket spring can be folded; when the mattress is packaged, the mattress can be compressed and folded at the first folding line 24 and the second folding line 25 of the mattress, the upper part of the spring layer 20 is folded toward the second transverse area 22 along the first folding line 24, and the lower part of the spring layer 20 is folded toward the second transverse area 22 along the second folding line 25. The lower part of the spring layer 20 can be overlapped with the upper part of the spring layer 20, or the lower part of the spring layer 20 and the upper part of the spring layer 20 can be folded on two opposite surfaces of the second transverse area 22 respectively. The folded mattress can be wound around a winding axis perpendicular to the first folding line 24 and the second folding line 25, thereby achieving lower cost, better supporting capacity and smaller packaging size that is more suitable for transportation purposes.

[0060] like Figure 4 As shown, a partitioned spring mattress packaging method according to a first embodiment of the present invention includes:

[0061] A compressed mattress includes a partitioned spring layer 20, and the spring layer 20 includes at least a first transverse zone 21, a second transverse zone 22, and a third transverse zone 23, which are arranged adjacent to each other in sequence. The second transverse zone 22 is located between the first transverse zone 21 and the third transverse zone 23. The second transverse zone 22 includes a spiral line and a coil, and the spiral line extends longitudinally along the mattress and connects adjacent coils in the second transverse zone one by one. The coil is a wire drawing spring or a Bonnier spring, and it has no separate, independent spring coils. The elasticity of the spiral line is not as good as that of the coil. If it is folded or bent beyond a certain angle, the spiral line cannot return to its original shape. In other embodiments, the spiral line can also be replaced by a connecting steel wire with other similar structures that connects adjacent coils and cannot be folded or wound by itself. The first transverse zone 21 and the third transverse zone 23 each include independent coils wrapped in independent cloth bags, that is, the first transverse zone 21 and the third transverse zone 23 include pocket springs. The mattress has a first folding line 24 and a second folding line 25 extending transversely along the mattress, and the first folding line 24 and the second folding line 25 pass through the first transverse zone 21 and the third transverse zone 23 respectively.

[0062] After the mattress is compressed, the upper part of the spring layer 20 is folded along the first folding line 24 toward the second transverse region 22, and the lower part of the spring layer 20 is folded along the second folding line 25 toward the second transverse region 22. The lower part of the spring layer 20 can be stacked with the upper part of the spring layer 20, or the lower part of the spring layer 20 and the upper part of the spring layer 20 can be folded on two opposite surfaces of the second transverse region 22 respectively, so that a three-layer mattress stacked on each other is formed after folding.

[0063] The compressed and folded mattress is rolled up around a rolling axis perpendicular to the first folding line 24 and the second folding line 25, with the spiral line parallel to the rolling axis.

[0064] A method for packaging a partitioned spring mattress according to an embodiment of the present invention, when packaging the mattress, the mattress can be compressed and then folded at the first folding line 24 and the second folding line 25 of the mattress, the upper part of the spring layer 20 is folded along the first folding line 24 to the second lateral zone 22, the lower part of the spring layer 20 is folded along the second folding line 25 to the second lateral zone 22, and the lower part of the spring layer 20 and the upper part of the spring layer 20 are stacked on each other, and the folded mattress can be wound around a winding axis perpendicular to the first folding line 24 and the second folding line 25, thereby achieving lower cost, better supporting capacity and smaller packaging size that is more suitable for transportation purposes.

[0065] The mattress has a centerline 26 extending in the transverse direction of the mattress, and the centerline 26 passes through the second transverse region 22. The distance of the second fold line 25 from the centerline 26 is approximately equal to the distance of the first fold line 24 from the centerline 26. The centerline of the second transverse region 22 coincides with the centerline 26 of the mattress. The distance of the first fold line 24 from the top of the mattress, the distance of the first fold line 24 from the second fold line 25, and the distance of the second fold line 25 from the top of the mattress are approximately equal, forming a tri-fold mattress.

[0066] The wire diameter of the independent coil in the first transverse zone 21 is smaller than that of the coil in the second transverse zone 22; the wire diameter of the independent coil in the third transverse zone 23 is smaller than that of the coil in the second transverse zone 22. When the wire diameter of the pocket spring is smaller than that of the brushed wire spring or the Bonnier spring, the support capacity of the pocket spring is still better than that of the brushed wire spring or the Bonnier spring, so it can provide better support to the user.

[0067] Embodiment 2

[0068] like Figure 5 As shown, a partitioned spring mattress according to the second embodiment of the present invention includes a partitioned spring layer 20, wherein the spring layer 20 includes a first transverse zone 21, a second transverse zone 22 and a third transverse zone 23 which are arranged adjacent to each other in sequence; the spring layer 20 also includes a fourth transverse zone 27 and a fifth transverse zone 28.

[0069] The second transverse zone 22 is located between the first transverse zone 21 and the third transverse zone 23. The second transverse zone 22 includes a spiral wire and a coil. The spiral wire extends longitudinally along the mattress and connects adjacent coils in the second transverse zone one by one. The coil is a wire drawing spring or a Bonnier spring, and it does not have a separate, independent spring coil. The elasticity of the spiral wire is not as good as the elasticity of the coil. If it is folded or bent beyond a certain angle, the spiral wire cannot return to its original shape. In other embodiments, the spiral wire can also be replaced by a connecting steel wire with other similar structures that connects adjacent coils and cannot be folded or wound by itself. The first transverse zone 21 and the third transverse zone 23 each include independent coils wrapped in independent cloth bags, that is, the first transverse zone 21 and the third transverse zone 23 include pocket springs.

[0070] The fourth transverse zone 27 is arranged adjacent to the third transverse zone 23. The fourth transverse zone 27 includes a spiral wire and a coil. The spiral wire extends along the longitudinal direction of the mattress and connects the adjacent coils in the fourth transverse zone 27 one by one. The coil is a wire drawing spring or a Bonnier spring, which has no separate, independent spring coils. The elasticity of the spiral wire is not as good as the elasticity of the coil. If it is folded or bent beyond a certain angle, the spiral wire cannot be restored to its original shape. In other embodiments, the spiral wire can also be replaced by a connecting steel wire with other similar structures that connects adjacent coils and cannot be folded or wound by itself. The fifth transverse zone 28 is arranged adjacent to the first transverse zone 21. The fifth transverse zone 28 includes a spiral wire and a coil. The spiral wire extends along the longitudinal direction of the mattress and connects the adjacent coils in the fifth transverse zone 28 one by one. The coil is a wire drawing spring or a Bonnier spring, which has no separate, independent spring coils. The elasticity of the spiral wire is not as good as the elasticity of the coil. If it is folded or bent beyond a certain angle, the spiral wire cannot be restored to its original shape. In other embodiments, the spiral wire can also be replaced by a connecting steel wire with other similar structures that connects adjacent coils and cannot be folded or wound by itself.

[0071] The mattress has a first folding line 24 and a second folding line 25 extending in the transverse direction of the mattress. The first folding line 24 and the second folding line 25 pass through the first transverse zone 21 and the third transverse zone 23 respectively, so that the upper part of the spring layer 20 can be folded toward the second transverse zone 22 along the first folding line 24, and the lower part of the spring layer 20 can be folded toward the second transverse zone 22 along the second folding line 25. The lower part of the spring layer 20 can be stacked with the upper part of the spring layer 20, or the lower part of the spring layer 20 and the upper part of the spring layer 20 can be folded on two opposite surfaces of the second transverse zone 22 respectively, so that a three-layer mattress stacked on each other is formed after folding.

[0072] The mattress has a centerline 26 extending in the transverse direction of the mattress, and the centerline 26 passes through the second transverse region 22. The distance between the second fold line 25 and the centerline 26 is approximately equal to the distance between the first fold line 24 and the centerline 26. The centerline of the second transverse region 22 coincides with the centerline 26 of the mattress. The distance between the first fold line 24 and the top of the mattress, the distance between the first fold line 24 and the second fold line 25, and the distance between the second fold line 25 and the bottom of the mattress are approximately equal, forming a tri-fold mattress.

[0073] The wire diameter of the independent coil in the first transverse zone 21 is smaller than the wire diameter of the coil in the second transverse zone 22, the fourth transverse zone 27 and the fifth transverse zone 28; the wire diameter of the independent coil in the third transverse zone 23 is smaller than the wire diameter of the coil in the second transverse zone 22, the fourth transverse zone 27 and the fifth transverse zone 28. When the wire diameter of the pocket spring is smaller than that of the wire drawing spring or the Bonnier spring, the support capacity of the pocket spring is still better than that of the wire drawing spring or the Bonnier spring, so it can provide better support for the user.

[0074] The coil is a brushed wire spring or a Bonnier spring, which has no separate, independent spring coils. Due to the different production processes, the production cost of the brushed wire spring or the Bonnier spring is lower than that of the pocket spring. Therefore, the partitioned spring layer of the present invention includes pocket springs and brushed wire springs or Bonnier springs, and the production cost is lower than that of a spring mattress that is entirely pocket springs.

[0075] The zoned spring mattress further comprises a mattress cover which completely encloses the first lateral zone 21 , the second lateral zone 22 , the third lateral zone 23 , the fourth lateral zone 27 and the fifth lateral zone 28 .

The center line 26 of the mattress passes through the second transverse zone 22; the first folding line 24 passes through the first transverse zone 21; and the second folding line 25 passes through the third transverse zone 23. The compressed fifth transverse zone 28 is folded toward the second transverse zone 22 along the first folding line 24, and the fourth transverse zone 27 is folded toward the second transverse zone 22 along the second folding line 25. The fourth transverse zone 27 can be stacked on the fifth transverse zone 28, that is, the lower part of the spring layer 20 and the upper part of the spring layer 20 are stacked on each other, or the fourth transverse zone 27 and the fifth transverse zone 28 can be folded on two opposite surfaces of the second transverse zone 22, respectively, to form a three-layer mattress stacked on each other after folding. The compressed and folded mattress is wound around a winding axis approximately perpendicular to the first folding line 24 and the second folding line 25, and the spiral line is parallel to the winding axis. When the mattress is rolled, the spiral line is parallel to the rolling axis and remains straight, and the spiral line is not folded or bent after the mattress is folded.

[0077] In the partitioned spring mattress of the present embodiment, the spring layer of the mattress adopts a segmented structure, the ordinary spring and the pocket spring are connected by a connector, the center line 26 of the mattress passes through the ordinary spring, and the first folding line 24 and the second folding line 25 pass through the pocket spring. The spiral line of the ordinary spring is arranged along the length direction of the mattress, that is, it extends along the longitudinal direction of the mattress, and the pocket spring can be folded; when the mattress is packaged, the mattress can be folded at the first folding line 24 and the second folding line 25 of the mattress after being compressed, the upper part of the spring layer 20 is folded along the first folding line 24 to the second transverse area 22, and the lower part of the spring layer 20 is folded along the second folding line 25 to the second transverse area 22, the lower part of the spring layer 20 can be overlapped with the upper part of the spring layer 20, or the lower part of the spring layer 20 and the upper part of the spring layer 20 can be folded on two opposite surfaces of the second transverse area 22, and the folded mattress can be wound around a winding axis perpendicular to the first folding line 24 and the second folding line 25, so as to achieve low cost, good support capacity and smaller packaging size for transportation purposes.

[0079] The compressed mattress comprises a partitioned spring layer 20 , wherein the spring layer 20 comprises a first transverse zone 21 , a second transverse zone 22 and a third transverse zone 23 which are arranged adjacent to each other in sequence; the spring layer 20 further comprises a fourth transverse zone 27 and a fifth transverse zone 28 .

[0080] The second transverse zone 22 is located between the first transverse zone 21 and the third transverse zone 23. The second transverse zone 22 includes a spiral wire and a coil. The spiral wire extends longitudinally along the mattress and connects adjacent coils in the second transverse zone one by one. The coil is a wire drawing spring or a Bonnier spring, and it does not have a separate, independent spring coil. The elasticity of the spiral wire is not as good as the elasticity of the coil. If it is folded or bent beyond a certain angle, the spiral wire cannot return to its original shape. In other embodiments, the spiral wire can also be replaced by a connecting steel wire with other similar structures that connects adjacent coils and cannot be folded or wound by itself. The first transverse zone 21 and the third transverse zone 23 each include independent coils wrapped in independent cloth bags, that is, the first transverse zone 21 and the third transverse zone 23 include pocket springs.

[0081] The fourth transverse zone 27 is arranged adjacent to the third transverse zone 23. The fourth transverse zone 27 includes a spiral wire and a coil. The spiral wire extends along the longitudinal direction of the mattress and connects the adjacent coils in the fourth transverse zone 27 one by one.

The fifth transverse zone 28 is arranged adjacent to the first transverse zone 21. The fifth transverse zone 28 includes a spiral wire and a coil.

The coil is a wire drawing spring or a Bonnier spring, which has no separate, independent spring coils. The elasticity of the spiral wire is not as good as the elasticity of the coil. If it is folded or bent beyond a certain angle, the spiral wire cannot be restored to its original shape.

[0083] After the mattress is compressed, the compressed fifth transverse zone 28 is folded along the first folding line 24 toward the second transverse zone 22, and at the same time, the fourth transverse zone 27 is folded along the second folding line 25 toward the second transverse zone 22. The fourth transverse zone 27 can be stacked on the fifth transverse zone 28, that is, the lower part of the spring layer 20 and the upper part of the spring layer 20 are stacked on each other, or the fourth transverse zone 27 and the fifth transverse zone 28 can be folded on two opposite surfaces of the second transverse zone 22 respectively, to form a three-layer mattress stacked on each other after folding.

[0084] The compressed and folded mattress is rolled around a winding axis perpendicular to the first folding line 24 and the second folding line 25, and the spiral line is parallel to the winding axis.

The distance of the second fold line 25 from the centerline 26 is approximately equal to the distance of the first fold line 24 from the centerline 26.

The distance of the first fold line 24 from the top of the mattress, the distance of the first fold line 24 from the second fold line 25, and the distance of the second fold line 25 from the top of the mattress are approximately equal, forming a tri-fold mattress.
