Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of soft cushion furniture, in particular to a spring soft cushion and a soft cushion product. BACKGROUND
[0002] The spring soft cushion has certain flexibility and elasticity, and can be used in various furniture products, for example, for making a mattress or a sofa cushion. The spring soft cushion generally comprises upper and lower layers of cloth, and a plurality of springs are wrapped in an array between the two layers of cloth. Each spring is independently encapsulated in a certain area by setting a sewing line, a welding point or a welding line around the spring, so as to form the spring soft cushion.
[0003] However, since the spring can stretch the cloth by its elasticity, the cloth between adjacent springs has a large wrinkle and a relatively large activity range, which causes the entire spring soft cushion to have a large ductility, thereby causing the size of the spring soft cushion to be unstable. When the spring soft cushion is used as a component to make a mattress or a sofa cushion product, it needs to be fixedly connected with other components such as a sponge pad, a bed net and the like in advance, so as to fix the size of the spring soft cushion, and then to coat an external fabric and a decorative layer. This causes problems such as complex production process and low assembly efficiency. CONTENT OF THE UTILITY MODEL

[0011] In some embodiments of the first aspect of the present application, the side wall portion is provided with a vertical partition structure for separating adjacent accommodation cavities in the same row from each other.
[0012] In some embodiments of the first aspect of the present application, the side wall portion of adjacent elastic units is provided with the vertical partition structure along the first direction.

When the spring cushion is used to manufacture a mattress or a sofa cushion, there is no need to additionally provide other components to assist in fixing the size of the spring cushion, and the spring cushion can be directly subjected to processes such as coating of an external fabric and a decorative layer, thereby simplifying the production and assembly process of the spring cushion when applied, and improving the assembly efficiency.

Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.
[0034] First aspect, see Figures 1 to 3The application provides a spring cushion 100, which comprises a first packaging layer 10, a second packaging layer 20, a separation structure 30 and a plurality of springs 40. The first packaging layer 10 is arranged in a flat manner, the second packaging layer 20 is arranged in a bent manner on one side of the first packaging layer 10, and a plurality of accommodation cavities 111 for accommodating the springs 40 are formed in the second packaging layer 20. The separation structure 30 is arranged around the accommodation cavities 111 and is used for separating two adjacent accommodation cavities 111, each of the accommodation cavities 111 accommodates one spring 40 and forms an elastic unit 41. The first packaging layer 10 is used for limiting the relative movement between two adjacent elastic units 41.
[0035] After the first packaging layer 10 and the second packaging layer 20 are connected, the plurality of springs 40 can be packaged in the accommodation cavities 111. In order to avoid the mutual entanglement and collision between the plurality of springs 40, the separation structure 30 is used to separate the adjacent accommodation cavities 111, one spring 40 is arranged in one accommodation cavity 111, and the mutual interference between the springs 40 can be avoided, so that the independence of each spring 40 is ensured. The spring 40 can separate the second packaging layer 20 by using the elasticity of the spring 40, and each spring 40 and the packaging layer cloth around the spring 40 form a relatively independent elastic unit 41. The two adjacent elastic units 41 are connected by the separation structure 30, so that the relative movement amplitude between the elastic units 41 is large. For example, the elastic unit 41 can swing and bend around the axis of the spring 40, and the two adjacent elastic units 41 can also move close to or away from each other.
[0036] At this time, the first packaging layer 10 is arranged in a flat manner, and the deformability of the first packaging layer 10 is controlled, so that the first packaging layer 10 can be used to limit the relative movement amplitude between the elastic units 41, that is, the first packaging layer 10 is used to “tie” the plurality of freely movable elastic units 41, so as to constrain the elastic units 41, thereby reducing the deformability of the entire spring cushion 100 and reducing the deformation amplitude of the size of the spring cushion 100. When the spring cushion 100 is used to manufacture a mattress 200 or a sofa cushion, it is not necessary to additionally arrange other components to assist in fixing the size of the spring cushion 100, and the spring cushion 100 can be directly subjected to a process of coating an external fabric and a decorative layer, so as to simplify the production and assembly process of the spring cushion 100 in application and improve the assembly efficiency. Compared with additionally arranging other packaging structures outside the first packaging layer 10 or the second packaging layer 20 to limit the movement of the elastic units 41, the first packaging layer 10 is directly used to constrain the elastic units 41 in the application, so that the number of components constituting the spring cushion 100 can be reduced, and the number of structure layers can be reduced, thereby simplifying the structure of the entire spring cushion 100.
[0037] Optionally, the first encapsulation layer 10 can limit the relative movement of the elastic unit 41 in several different ways. For example, in a first example, the area of the first encapsulation layer 10 can be set to be smaller, such as the area of the first encapsulation layer 10 being smaller than the area of the second encapsulation layer 20. This reduces the deformability of the first encapsulation layer 10, allowing it to fix or constrain the movement of the elastic unit 41. In a second example, a material with lower ductility can be used for the first encapsulation layer 10, i.e., the ductility of the first encapsulation layer 10 is less than that of the second encapsulation layer 20, such as a low-elasticity fabric, thereby reducing the deformability of the first encapsulation layer 10. Of course, in a third example, the methods of the above two examples can be combined, i.e., both a low-elasticity fabric and a reduced area of the first encapsulation layer 10 can be used to limit the movement of the elastic unit 41.
[0038] In some embodiments, the partition structure 30 is formed by at least one of the following methods: ultrasonic welding, thermal welding, and sewing. These methods are well-established processes in the manufacture of upholstered furniture, making the partition structure 30 easy to implement.
[0039] In some embodiments, the partition structure 30 may be configured in at least one of the following ways: discrete joint points, continuous joint segments, or discrete joint segments or joint curves. Using joint points, joint lines, or other methods to configure the connection structure makes the partition structure 30 easy to implement. Taking ultrasonic welding as an example, discrete joint points can be achieved through discontinuous spot welding, continuous joint segments can be achieved through continuous welding, and discrete joint segments can be achieved through multiple short-distance continuous welds. The specific configuration of the partition structure 30 can be flexibly selected according to the size of the spring pad 100 and design requirements.
[0040] In some embodiments, the elastic element 41 is along a first direction (e.g. Figure 4 (as shown in the x-direction) and the second direction ... Figure 4 The flexible units are arranged in a matrix or staggered array (as shown in the y-direction), with the first and second directions perpendicular to each other, and the plane containing the first and second directions parallel to the first encapsulation layer 10. This helps to make the arrangement of the flexible units more orderly and reasonable, and the array arrangement also makes the partition structure 30 more compact.
[0041] Of course, in other examples, the arrangement of springs 40 can be in addition to array arrangement, such as along the ring direction, or other irregular arrangement. The specific arrangement can be based on the overall outline shape of the spring pad 100, and is not limited here.
[0042] In some embodiments, the spring cushion 100 has an elastic elongation of less than 5% in the first direction and the second direction. When the entire spring cushion 100 is size-limited by the first packaging layer 10, the spring cushion 100 can have an elastic elongation of less than 5% in the laying direction, that is, the entire spring cushion 100 does not have a large deformation or only has a small deformation under the constraint of the first packaging layer 10 when the spring cushion 100 is not subjected to external force (in the laying state), so that the spring cushion 100 can maintain the size substantially unchanged.
[0043] In some embodiments, the side wall part 22 of the adjacent elastic unit 41 is provided with the separation structure 30 along the first direction, and the plurality of separation structures 30 on the side wall part 22 are arranged in line along the first direction. By arranging the separation structures 30 on the side wall part 22 in line, the processing operation of the separation structures 30 on the side wall part 22 can be simplified, for example, the ultrasonic welding can be performed along the first direction, and the arrangement of the separation structures 30 in the spring cushion 100 can be more orderly and reasonable.
[0044] In some embodiments, the second packaging layer 20 is bent to form the side wall part 22 and the top part 23 connected to each other, the side wall part 22 and the top part 23 are connected to the first packaging layer 10 to form the accommodation cavity 111, and the bottom of the side wall part 22 is connected to the first packaging layer 10 to form the separation structure 30. By using the bending shape of the second packaging layer 20 itself, the accommodation cavity 111 can be constructed, and by connecting the bottom of the side wall part 22 to the first packaging layer 10, the connection distance between the second packaging layer 20 and the first packaging layer 10 can be shortened, so that the structure of the spring cushion 100 is more simple.
[0045] In some embodiments, referring to Figures 4 to 8 , the side wall part 22 is provided with a vertical separation structure 31 for separating the adjacent accommodation cavities 111 in the same row from each other.
[0046] Optionally, the vertical separation structure 31 can be arranged linearly in the vertical direction, as shown in Figure 4 and Figure 5 , the spring 40 is selected to have a constant diameter in the axial direction, so that the side wall part 22 of the accommodation cavity 111 is linearly arranged. Of course, in other examples, as shown in Figure 8 , the spring 40 can be selected to have a variable diameter, that is, the diameter of the middle part of the spring is large, and the diameter of one or both ends is small. At this time, the accommodation cavity 111 can be arranged in a drum shape, and therefore the vertical separation structure 31 can be arranged in a curved shape.
[0047] In some embodiments, the side wall portion 22 of the adjacent elastic unit 41 is provided with the vertical partition structure 31 in the first direction, and the projection of the vertical partition structure 31 on the first packaging layer 10 falls on the partition structure 30 in the first direction or falls on the extension line of the partition structure 30 in the first direction. With this arrangement, on the one hand, the arrangement of the vertical partition structure 31 is more orderly, and on the other hand, the projection of the vertical partition structure 31 and the partition structure 30 is overlapped, which can make the fiber direction of the second packaging layer 20 more orderly, and the structure of the spring cushion 100 more regular.
[0048] In some embodiments, the vertical partition structure 31 is used to limit the relative movement between the two elastic units 41. With the vertical partition structure 31, in addition to being able to separate the two adjacent accommodation cavities 111, the vertical partition structure 31 itself can also be used to connect and constrain the two adjacent elastic units 41, so that the two elastic units 41 on both sides of the vertical partition structure 31 are difficult to move relatively (such as twisting, moving closer or moving away, etc.), thereby reducing the degree of freedom of the elastic unit 41, further reducing the deformability of the spring cushion 100, and reducing the amplitude of the size change of the spring cushion 100.
[0049] In some embodiments, the vertical partition structure 31 is also used to limit the bending deformation of the elastic unit 41 in the axial direction. By providing the vertical partition structure 31, the elastic unit 41 between the two adjacent vertical partition structures 31 can obtain the effect of being "clamped". When the length of the spring 40 arranged in the accommodation cavity 111 is large, the spring 40 has the ability to bend in the axial direction. At this time, the vertical partition structure 31 can be used to support the elastic unit 41 to some extent, so that the elastic unit 41 is more upright, which helps to prevent the elastic unit 41 from bending in the axial direction.
[0050] Of course, in other examples, the vertical partition structure 31 can also have no ductility (or have very low ductility), which can obtain better constraint effect.
[0051] For example, the vertical partition structure 31 can also be formed by ultrasonic welding, heat welding or sewing. After the fabric of the side wall portion 22 is subjected to ultrasonic welding, heat welding or sewing operation to obtain the vertical partition structure 31, it is helpful to reduce the ductility or increase the hardness of the fabric at the position of the side wall portion 22 (for example, the fabric is melted and denatured after welding, or a high-density sewing can provide a certain supporting force, etc.), thereby achieving the constraint effect on the deformation of the elastic unit 41.
[0052] Please refer to Figure 9, the assembly of the spring cushion 100 can be carried out in the following manner: when the spring 40 selected by the spring cushion 100 is large (i.e. the spring 40 has a large size in the axial direction), the spring 40 has a large elasticity, and it is difficult to directly sew the first packaging layer 10 and the second packaging layer by compressing the spring 40. Therefore, the second packaging layer 20 can be welded or sewn first, for example, the second packaging layer 20 is first bent to form a receiving cavity, and the side wall part 22 of the receiving cavity is welded to form a vertical partition structure 31, at this time, the second packaging layer 20 can form a plurality of independent receiving cavities 111. Then, the spring 40 is correspondingly placed in the receiving cavity 111, and finally, the first packaging layer 10 and the second packaging layer 20 are fixedly connected (sewing or welding, etc.), see Figure 9 the dashed arrow direction in FIG. 13, the dashed arrow is a combination of the first packaging layer 10 and the second packaging layer 20, thereby obtaining a finished product of the spring cushion 100.
[0053] In the second aspect, please refer to Figure 10 The application also provides a cushion product, which comprises the spring cushion 100 provided in the first aspect, and the cushion product comprises one of a mattress 200, a sofa cushion, and a seat cushion. The spring cushion 100 can be applied to the fields of the mattress 200, the sofa cushion, and the seat cushion, and is assembled and processed in cooperation with other support structures (such as a bed frame, a sofa support), and external fabrics, decorative layers, and the like, thereby obtaining corresponding furniture containing the spring cushion 100.
[0054] The embodiments of the application are described in detail above with reference to the drawings, but the application is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the application. In addition, the embodiments of the application and the features in the embodiments can be combined with each other without conflict.
