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 two 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

[0004] To solve at least one of the above technical problems, the present application provides a spring soft cushion and a soft cushion product, which can limit the size of the spring soft cushion, so that the spring soft cushion is not easy to deform, and the production process is simplified. The technical solutions adopted are as follows.

[0005] The spring soft cushion provided in the first aspect of the present application comprises a first encapsulation layer, a second encapsulation layer, a separation structure, a surface layer and a plurality of springs. The first encapsulation layer and the second encapsulation layer mutually enclose to form an accommodation space. The separation structure is used to separate the accommodation space into a plurality of subspaces. A part of the first encapsulation layer and a part of the second encapsulation layer are close to each other and connected to form the separation structure. Each of the subspaces accommodates one of the springs and forms an elastic unit. The surface layer is connected to one side of the first encapsulation layer away from the accommodation space through a connecting structure. The surface layer is used to limit the relative movement between the plurality of elastic units.

[0006] In some embodiments of the first aspect of the present application, the connecting structure comprises a contour connecting point or a contour connecting line for fixing the contour of the surface layer. The contour connecting point or the contour connecting line is arranged along the contour of the surface layer.

[0007] In some embodiments of the first aspect of the present application, the connecting structure comprises an abdominal connecting point or an abdominal connecting line for fixing the abdominal part of the surface layer.

[0008] In some embodiments of the first aspect of the present application, the partition structures are arranged in an array on the first encapsulation layer, and the belly connecting points are arranged to overlap part of the partition structures.

[0009] In some embodiments of the first aspect of the present application, the distance between two adjacent belly connecting points is greater than or equal to the space required to accommodate two springs.

[0010] In some embodiments of the first aspect of the present application, the face layer is provided in two, one of which is arranged on the side of the first encapsulation layer away from the accommodation space, and the other is arranged on the side of the second encapsulation layer away from the accommodation space.

[0011] In some embodiments of the first aspect of the present application, the connecting structure includes at least a connecting point or a connecting line, which is arranged at least on the contour or the belly of the face layer, and the connecting point or the connecting line penetrates both face layers.

[0012] In some embodiments of the first aspect of the present application, the connecting structure is formed by at least one of ultrasonic welding, sewing, heat welding, and snap fastening.

[0013] In some embodiments of the first aspect of the present application, the side of the face layer facing the accommodation space is further provided with an interlayer or a buffer layer.

[0014] In some embodiments of the first aspect of the present application, the elastic stretchability of the spring cushion in the flat state is less than 5%.

[0015] In a second aspect, the present application also provides a cushion product, which includes the spring cushion provided in the first aspect, and the cushion product includes one of a mattress, a sofa cushion, and a seat cushion.

[0016] The embodiments of the present application have at least the following beneficial effects: by providing a face layer and connecting the fabric layer to the first encapsulation layer through the connecting structure, and controlling the deformability of the face layer, the relative movement range between the elastic units can be limited by the face layer, i.e., the multiple freely movable elastic units are “tied up” by the face layer, which plays a role in restricting the elastic units, thereby reducing the deformability of the entire spring cushion and reducing the deformation range of the size of the spring cushion. 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 in application and improving the assembly efficiency.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0033] 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 partition structure 30, a plurality of springs 40 and a surface layer 50. The first packaging layer 10 and the second packaging layer 20 are mutually closed to form a containing space, the partition structure 30 is used for separating the containing space into a plurality of subspaces 111, a part of the first packaging layer 10 and the second packaging layer 20 are close to each other and connected to form the partition structure 30, one spring 40 is contained in each subspace 111 and forms an elastic unit 41, and the surface layer 50 is connected to one side of the first packaging layer 10 away from the containing space through a connecting structure 51, and the surface layer 50 is used for limiting the relative movement between the plurality of elastic units 41.

[0034] After the first packaging layer 10 and the second packaging layer 20 are connected, the plurality of springs 40 can be packaged in the containing space, in order to avoid the mutual entanglement and collision between the plurality of springs 40, therefore, the containing space as a whole is separated into a plurality of independent subspaces 111 by the partition structure 30, one spring 40 is placed in one subspace 111, the mutual interference between the springs 40 can be avoided, and the independence of each spring 40 is ensured. The first packaging layer 10 and the second packaging layer 20 are separated from each other by the elasticity of the spring 40, and each spring 40 and the packaging layer fabric around the spring 40 constitute a relatively independent elastic unit 41. The adjacent two elastic units 41 are connected to each other in dependence on the partition structure 30, therefore, 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 adjacent two elastic units 41 can also move close to or away from each other.

[0035] At this time, by arranging the surface layer 50, the fabric layer is connected to the first packaging layer 10 through the connecting structure 51, and the deformability of the surface layer 50 is controlled, so that the relative movement amplitude between the elastic units 41 can be limited by the surface layer 50, that is, the plurality of freely movable elastic units 41 are “tied up” by the surface layer 50, and the constraint effect on the elastic units 41 is achieved, so that the deformability of the entire spring cushion 100 is reduced, and the deformation amplitude of the size of the spring cushion 100 is reduced. When the spring cushion 100 is applied to manufacture a mattress 200 and a sofa cushion, other components do not need to be additionally arranged to assist in fixing the size of the spring cushion 100, the spring cushion 100 can directly perform a process of coating an external fabric and a decorative layer and the like, so that the production and assembly process of the spring cushion 100 in application is simplified, and the assembly efficiency is improved.

[0036] Optionally, when the entire spring cushion 100 is dimensionally limited by the surface layer 50, the spring cushion 100 can have an elastic stretchability in the laying direction of less than 5%, that is, under the constraint of the surface layer 50, the entire spring cushion 100 hardly deforms or only slightly deforms under the action of an external force (when the spring cushion 100 is laid flat), so that the spring cushion 100 can maintain its original size.

[0037] Optionally, the relative movement of the elastic unit 41 can be limited by the surface layer 50 in the following different ways. For example, in the first example, the surface layer 50 can have a smaller area, for example, the area of the surface layer 50 is smaller than the area of the first packaging layer 10, so that the deformability of the surface layer 50 is reduced, and the surface layer 50 can fix or constrain the movement of the elastic unit 41. In the second example, the surface layer 50 can be made of a material with lower ductility, that is, the surface layer 50 has lower ductility than the first packaging layer 10, for example, a low-elastic fabric is used, so that the deformability of the surface layer 50 is reduced. Of course, in the third example, the two examples above can be combined, that is, a low-elastic fabric is used and the area of the surface layer 50 is reduced, so that the elastic unit 41 is limited.

[0038] Optionally, the connection structure 51 can be formed by at least one of the following methods: ultrasonic welding, sewing, heat welding, and snap fastening. The above implementation methods have mature processes in the manufacturing process of the soft cushion furniture, so that the connection structure 51 is easy to implement.

[0039] Optionally, the partition structure 30 can also be implemented by ultrasonic welding, sewing, heat welding, etc., and the specific forming process can refer to the connection structure 51, which will not be described here.

[0040] In some embodiments, referring to Figures 3 to 5 , the connection structure 51 includes a contour connecting point 511 or a contour connecting line 512 for fixing the contour of the surface layer 50, and the contour connecting point 511 or the contour connecting line 512 is arranged along the contour of the surface layer 50. By arranging the connection structure 51 along the contour of the surface layer 50, the surface layer 50 can be first attached to the first packaging layer 10, and second, the movement of the elastic unit 41 in the peripheral direction can be constrained. The connection structure 51 can be arranged by connection points, connection lines, etc., so that the connection structure 51 is easy to implement. It can be understood that the contour connecting point 511 is arranged dispersedly along the contour direction of the surface layer 50, and the contour connecting line 512 is arranged continuously along the contour direction of the surface layer 50. Taking ultrasonic welding as an example, the contour connecting point 511 can be implemented by discontinuous spot welding, and the contour connecting line 512 can be implemented by continuous welding.

[0041] In some embodiments, the connecting structure 51 comprises an abdominal connecting point 513 or an abdominal connecting line 514 for fixing the abdominal part of the surface layer 50. By providing the abdominal connecting point 513 or the abdominal connecting line 514, the connecting position between the surface layer 50 and the elastic unit 41 can be increased while the periphery of the spring mattress 100 is constrained, and the constraint effect of the surface layer 50 on the elastic unit 41 in the abdominal area of the spring mattress 100 can be further improved. It can be understood that the abdominal part of the surface layer 50 refers to the area of the surface layer 50 other than the outer contour, and therefore the provision of the abdominal connecting point 513 or the abdominal connecting line 514 also helps to improve the stability of the connection between the surface layer and the first packaging layer 10.

[0042] In some embodiments, the partition structure 30 is arranged in an array on the first packaging layer 10, and the abdominal connecting point 513 is arranged to overlap part of the partition structure 30. The array arrangement of the partition structure 30 helps to make the arrangement of the sub-space 111 more orderly and reasonable, and the array arrangement also makes the partition structure 30 more compact. On this basis, the abdominal connecting point 513 is arranged to overlap part of the partition structure 30, which can reduce the area occupied by the first packaging layer 10, and make the connecting structure 51 more compact.

[0043] Of course, in other examples, the arrangement of the spring 40 can be in a circular direction or other special-shaped arrangement, which can be arranged according to the overall contour shape of the spring mattress 100, which is not limited here.

[0044] In some embodiments, the distance between two adjacent abdominal connecting points 513 is greater than or equal to the space required to accommodate two springs 40. The abdominal connecting point 513 can realize the connection between the surface layer 50 and the first packaging layer 10, and therefore the more dense the abdominal connecting point 513 is arranged, the more firmly the surface layer is connected to the first packaging layer 10. However, when the abdominal connecting point 513 is arranged too much, for example, the abdominal connecting point 513 is too dense so that the position between two adjacent elastic units 41 is also provided with the abdominal connecting point 513, which on the one hand will cause the surface layer 50 to be stretched too much, resulting in a decrease in the constraint effect of the surface layer 50 on the elastic unit 41, and on the other hand will also cause the processing time to increase, which is not conducive to efficiency. Therefore, the density of the abdominal connecting point 513 needs to be controlled within a reasonable range to avoid too dense arrangement of the abdominal connecting point 513. The space between two adjacent abdominal connecting points 513 is left for two or more springs 40, which can not only ensure sufficient connection strength between the surface layer 50 and the first packaging layer 10, but also ensure that the surface layer 50 maintains good constraint effect.

[0045] In some embodiments, please refer to Figures 6 to 8The two surface layers 50 are arranged on the surfaces of the first and second packaging layers 10 and 20, respectively, away from the accommodating space. The two surface layers 50 are arranged on the surfaces of the first and second packaging layers 10 and 20, respectively, away from the accommodating space. By arranging the two surface layers 50, the two sides of the elastic unit 41 can be constrained and positioned, thereby further improving the fixing effect of the surface layer 50 on the elastic unit 41 and further reducing the size deformation of the spring cushion 100.

[0046] In some embodiments, the connecting structure 51 at least includes a connecting point or a connecting line arranged at least on the contour or the abdomen of the surface layer 50, and the connecting point or the connecting line is arranged through the two surface layers 50. When the two surface layers 50 are arranged, the connecting point or the connecting line arranged through the two surface layers 50 can be used to fix the two surface layers 50 on the surfaces of the first and second packaging layers 10 and 20 at one time. On the one hand, the connecting stability of the two surface layers 50 can be improved, and the two surface layers 50 share one connecting structure 51, which can save the number of connecting structures 51 and simplify the structure of the spring cushion 100. On the other hand, the processing steps of the connecting structure 51 can be reduced, and the processing efficiency can be improved. For example, when the surface layer 50 is fixed by ultrasonic welding, the two surface layers 50 can be fixed on the two surfaces of the elastic unit 41 at one time, thereby shortening the processing time.

[0047] As an alternative embodiment, in addition to using the connecting structure 51 to fix the surface layer 50, the surface layer 50 can also be adhered to the surface of the first or second packaging layer 10 or 20 by using the gluing method.

[0048] In some embodiments, the surface layer 50 further comprises a cladding layer or a buffer layer (not shown) on the surface facing the accommodating space. By arranging the cladding layer or the buffer layer, the spring cushion 100 can have more functions to meet the needs of users, such as shock absorption, warmth, improved touch, etc., thereby further improving the use effect of the spring cushion 100.

[0049] In a second aspect, referring to Figure 9 The application also provides a cushion product comprising the spring cushion 100 provided in the first aspect. The spring cushion 100 can be applied to the fields of mattress 200, sofa cushion (not shown), seat cushion (not shown), etc., and is assembled and processed with other support structures (such as bed frame, sofa support), external fabric, decorative layer, etc., thereby obtaining corresponding furniture containing the spring cushion 100.

[0050] The embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made by those skilled in the art within the scope of knowledge of the technical field without departing from the spirit of the present application. Furthermore, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
