Description

Technical Field

[0004]

[0001] The present invention relates to the field of furniture, and specifically, to a spring package, a spring pad, furniture, and a method for manufacturing a spring package.

Background Art

[0002] Current furniture such as beds and sofas usually includes an elastic pad, and the elastic pad is generally formed by a number of stacked layers and springs, providing a comfortable use experience.

[0003] Spring pads that fit into independent backs are known, where each spring is independently packaged in a back or sleeve, and the spring backs are arranged to form spring back units according to a predetermined form. Next, the outside of the arranged spring back units is covered with a one-piece sponge rubber by pasting or adhering, etc., thereby forming a furniture pad or a spring pad like a furniture pad. In such a form, the springs can bend independently so as not to affect the surrounding springs, and the weight of the user can be more evenly distributed. At the same time, two or more people sitting or lying on the spring pad can reduce the interference with each other (for example, when the weight difference between individuals is relatively large, when one person turns over or moves the body, it is impossible to avoid affecting others), so the comfort of the user is improved.

[0004] Currently, the design of springback springs requires the installation of numerous assembly parts with different dimensions or structures. These assembly parts are then integrated to form the springback, and the spring package is then placed inside. This manufacturing method involves too many processing steps and is inefficient. Furthermore, because each part is manufactured independently through different processes, excessive errors in dimensions or structure can easily lead to mismatches between parts, making installation impossible. This negatively impacts the yield rate of the product and results in wasted raw materials and labor costs.

The sheet materials for manufacturing the flexible cover are manufactured by the same process, and even if there are errors in dimensions or structure compared to normal dimensions, the two sheet materials are exactly the same, so they can match each other, overlap smoothly, and connect to each other, contributing to reducing the impact of manufacturing errors and improving the yield rate of the product.

[Modes for carrying out the invention]

[0022] In the following, specific embodiments of the present application will be described in detail with reference to the drawings. Only preferred embodiments of the present application will be described herein, and other forms of the present application that can be realized by those skilled in the art based on the preferred embodiments will also be included in the scope of the present application.

[0023] The present invention provides a spring package, which is used to manufacture elastic pads for furniture such as beds and sofas.

[0024] Figures 1 and 2 show a spring package 100 according to a first embodiment, which includes a cone-shaped spring 110 and a flexible cover 120. In the embodiment shown in the drawings, the cone-shaped spring 100 is configured in a conical cross-section and has a large diameter end 111 and a small diameter end 112 opposite the large diameter end 111. It should be understood that cone-shaped springs configured in other shapes, such as a quadrilateral or polygonal cross-section, may also be used in the spring package according to the present invention. The flexible cover 120 is used to enclose the cone-shaped spring 110. The flexible cover 120 has a two-layer structure and includes an outer layer cover 121 that encloses the cone-shaped spring 110 from the outside, and an inner layer cover 122 that is located inside the cone-shaped spring 110 and encloses the cone-shaped spring 110 from the inside. The outer cover 121 and the inner cover 122 are connected at the large diameter end 111 and small diameter end 112, respectively, of a cone-shaped spring 110, so as to form an integrated flexible cover 120, thereby packaging the cone-shaped spring 110 inside the flexible cover 120.

[0025] In the spring package according to the present invention, the flexible cover is formed by overlapping two identical flexible sheet materials and connecting their corresponding edges. These two flexible covers may be referred to as the first flexible sheet material and the second flexible sheet material. Since the flexible sheet material for manufacturing the flexible cover only needs to have a single dimension and structure, in the actual manufacturing process, only one process for manufacturing the flexible cover is required, simplifying the processing process and improving manufacturing efficiency. Furthermore, since the flexible sheet materials are manufactured using the same process, all flexible sheet materials have substantially the same processing tolerances. As a result, even with tolerances, the flexible sheet materials can be overlapped and their corresponding edges can be connected, avoiding situations where different parts for manufacturing the flexible cover cannot be matched due to processing tolerances, and significantly improving the yield rate of the product.

[0026] Next, the manufacturing process of the spring package according to the present invention will be described in detail with reference to Figures 3 to 8.

[0027] As shown in Figure 7, in the first embodiment, the first flexible sheet material 123 and the second flexible sheet material 124 for making the flexible cover 120 are both circular or similar in shape, and their specific material may be nonwoven fabric.

[0028] When manufacturing the spring package, first, the first flexible sheet material 123, the cone-shaped spring 110, and the second flexible sheet material 124 are arranged along the axial direction of the cone-shaped spring 110 according to the configuration shown in Figure 3. Of these, the first flexible sheet material 123 corresponds to the small diameter end 112 of the cone-shaped spring 110, and the second flexible sheet material 124 corresponds to the large diameter end 111 of the cone-shaped spring 110. When viewed from the direction along the axial direction, the first flexible sheet material 123 and the second flexible sheet material 124 overlap.

[0029] Next, as shown in Figure 4, an axial pressure F is applied to the cone-shaped spring 110 so that it is compressed along the axial direction until it becomes flat. At the same time, the first flexible sheet material 123 and the second flexible sheet material 124 are attached at least at the edges.

[0030] Next, as shown in Figures 5 and 8, the edges of both the first flexible sheet material 123 and the second flexible sheet material 124 are connected to form a first connection portion 101. This first connection portion 101 is formed radially outward from the large diameter end 111 of the conical spring 110. Then, positions close to the center of both the first flexible sheet material 123 and the second flexible sheet material 124 are connected to form a second connection portion 102. This second connection portion 102 is formed radially inward from the small diameter end 112 of the conical spring 110. It is preferable that the second connection portion 102 is configured as an annular connection portion extending along the circumferential direction of the small diameter end 112. In this way, the connection formed on the small diameter end 112 is as close as possible to the conical spring 110, which is advantageous for the flexible cover 120 to stably hold the conical spring 110. It is preferable that the connection between the first flexible sheet material 123 and the second flexible sheet material 124 is achieved by sewing or ultrasonic welding.

[0031] Furthermore, as shown in Figure 6, after completing the connection, the axial pressure F biasing the cone-shaped spring 110 is released, the cone-shaped spring 110 is returned to its original shape, and the manufacturing of the spring package 100 is completed. In the first embodiment, the flexible sheet material corresponding to the small diameter end 112 of the cone-shaped spring 110 is formed independently on the outer layer cover 121 of the flexible cover 120, enclosing the outside of the cone-shaped spring 110 after the manufacturing is completed. After the cone-shaped spring 110 is returned to its original shape, the flexible sheet material corresponding to the large diameter end 111 of the cone-shaped spring 110 enters the inside of the cone-shaped spring 110 through the guiding function of the second connection part 102, enclosing the cone-shaped spring 110 from the inside, and is formed independently on the inner layer cover 122 of the flexible cover 120. As shown in Figures 1, 2, and 6, since the flexible sheet material is circular, after the cone-shaped spring 110 returns to its original shape, wrinkles are formed on both the outer cover 121 and the inner cover 122 that extend roughly along the generatrix of the cone-shaped spring 110.

[0032] Figures 9 to 17 illustrate the spring package 200 and its manufacturing process according to the second embodiment. The spring package 200 according to the second embodiment has substantially the same structure as the spring package 100 according to the first embodiment, but differs in the structure and manufacturing method of the flexible cover. This will now be explained in detail with reference to the drawings.

[0033] As shown in Figure 16, according to the second embodiment, the flexible sheet material for making the flexible cover (i.e., the first flexible sheet material 223 and the second flexible sheet material 224) is configured in a substantially convex hexagon, the convex hexagon comprising at least one pair of opposing and parallel first sides 225 and second sides 226, and two first adjacent sides 227 adjacent to the first side 225 and two second adjacent sides 228 adjacent to the second side 226.

[0034] Preferably, the first flexible sheet material 223 and the second flexible sheet material 224 are configured in a symmetrical shape, for example, symmetrical with respect to a line connecting the intersection points of the first adjacent side 227 and the second adjacent side 228 (i.e., dotted line AX1 in Figure 16), and symmetrical with respect to a line passing through the center points of both the first side 225 and the second side 226 and perpendicular to both (i.e., dotted line AX2 in Figure 16). In this case, the first side 225 and the second side 226 are practically the same side and can be interchanged with each other, and similarly, the first adjacent side 227 and the second adjacent side 228 are also the same side and can be interchanged with each other. For this reason, there is not just one opposing angle at which the two flexible sheet materials overlap. In the embodiment shown in the drawings, there are two opposing angles at which they overlap. Furthermore, if the structure of the flexible sheet material becomes a regular hexagon, the number of such opposing angles increases to six. This type of installation makes it easier to overlap the two flexible sheet materials, thus making them easier to process.

[0035] Preferably, the two first adjacent sides 227 are each formed at an obtuse angle with the first side 225. The angles α and β between each of the two first adjacent sides 227 and the first side 225 are the same, and the sum of the two angles α and β is equal to the sum of half the central angle of the sector (or a sector-like shape corresponding to a quadrilateral or polygonal cross-section) formed when the side surface of the conical spring 210 is unfolded, plus one flat angle. This is advantageous because, when the flexible sheet material constitutes the flexible cover 220, the generatrix of the first adjacent sides 227 and the conical spring 210 overlap, allowing the flexible cover 220 to be successfully attached to the conical spring 210.

[0036] When manufacturing the spring package according to the second embodiment, first, the first flexible sheet material 223 and the second flexible sheet material 224 are arranged overlapping, as shown in Figure 10.

[0037] Next, as shown in Figure 11, the corresponding first edges 225 and first adjacent edges 227 of both the first flexible sheet material 223 and the second flexible sheet material 224 are connected. At the same time, the second edge 226 is left unconnected. For the second adjacent edge 228, connection, non-connection, or partial connection can be selectively performed. Those skilled in the art can flexibly select according to the practical process. In the embodiment shown in the drawings, a portion of the second adjacent edge 228 near the first adjacent edge 227 is connected, while the portion of the second adjacent edge 228 near the second edge 226 is left unconnected. The process shown in Figure 11 configures the first flexible sheet material 223 and the second flexible sheet material 224 into a substantially drawstring structure.

[0038] Furthermore, as shown in Figure 12, the drawstring bag formed in the process shown in Figure 11 is turned inside out so that the joint between the first flexible sheet material 223 and the second flexible sheet material 224 is located inside the drawstring bag. After turning it inside out, the cone-shaped spring 210 is inserted into the drawstring bag so that the small diameter end 212 faces the first side 225.

[0039] Next, as shown in Figure 13, the unconnected edges of the first flexible sheet material 223 and the second flexible sheet material 224, namely the portion of the second adjacent edge 228 near the second edge 226 and the second edge 226, are connected. This packages the cone-shaped spring 210 inside the drawstring bag. At this time, the portion that encloses the outside of the cone-shaped spring 210 appears to constitute the outer layer cover 221 of the flexible cover 220, and this portion practically corresponds to the area enclosed by the first edge 225, the two first adjacent edges 227, and the dotted line AX1 in Figure 16.

[0040] Furthermore, as shown in Figure 14, the second side 226 is inserted into the conical spring 210 from the outside, around the large diameter end 211, and into the inside of the conical spring 210. In addition, as shown in Figure 15, the first side 225 and the second side 226 are connected at the small diameter end 212 of the conical spring 210, thereby forming a second connection portion 202 located radially inward from the small diameter end 212. The portion that has entered the inside of the conical spring 210 along with the second side 226 appears to constitute the inner layer cover 222 of the flexible cover 220, and this portion practically corresponds to the area enclosed by the second side 226, the two second adjacent sides 228, and the dotted line AX1 in Figure 16.

[0041] In the second embodiment, unlike the spring package 100 according to the first embodiment, the outer cover 221 and inner cover 222 of the flexible cover 220 are both commonly composed of a first flexible sheet material 223 and a part of the second flexible sheet material 224, and a connecting portion 203 shown in Figure 16 is formed between the two flexible sheet materials. The outer cover 221 and the inner cover 222 are connected at the large diameter end 211 of the conical spring 210 by the material of the flexible sheet material itself, and at the small diameter end 212 by the second connecting portion 202. Of these, the second connecting portion 202 is formed as an annular connecting portion located radially inward of the small diameter end 212 and extending along the circumferential direction of the small diameter end 212. Furthermore, since the flexible cover 220 is always manufactured and molded with the cone-shaped spring 210 not compressed, the outer cover 221 and inner cover 222 of the flexible cover 220 are formed with wrinkle-free, smooth surfaces.

[0042] Figure 17 shows another configuration of the flexible sheet material for manufacturing the flexible cover in the second embodiment. Of these, the first side 225' and the first adjacent side 227' of the flexible sheet material 223'(224') are the same as the configuration shown in Figure 16. The difference is that the second adjacent side 228' and the second side 226' are approximately perpendicular. This configuration gives the second side 226' a larger dimension. Thus, in the process shown in Figure 12, the opening formed by the unconnected second side 226' in the drawstring bag becomes larger in dimension, making it easier to insert the conical spring 210 into the drawstring bag. However, in this configuration, the flexible sheet material 223'(224') is not symmetrical with respect to the line connecting the intersections of both the first adjacent side 227' and the second adjacent side 228'. Therefore, it can be understood that there is a unique positioning relationship between the first flexible sheet material 223' and the second flexible sheet material 224', and between the first side 225' and the second side 226' and the conical spring 210. Of course, other configurations are possible; for example, the angle formed by the second adjacent side and the second side may be obtuse or acute.

[0043] Those skilled in the art will understand that in the second embodiment, the material and connection configuration of the flexible cover are the same as those described in the first embodiment.

[0044] A second aspect of the present invention further provides an elastic pad for manufacturing furniture, the elastic pad comprising a number of stacked layers (which may include, for example, sponge) and a spring package as described above. For example, the spring package is mounted on an elastic module formed on a base structure, the number of elastic modules are fixed to a mounting frame according to a planned arrangement via a structure such as a slide rail, and furthermore, stacked layers including sponge are laid in the arrangement of elastic modules, and finally, an elastic pad is formed.

[0045] A third aspect of the present invention further provides furniture which may comprise the above-described elastic pad and / or spring package.

[0046] According to the elastic pad and furniture of the present invention, technical effects similar to those obtained by the spring package of the present invention can be obtained.

[0047] The above description relating to some embodiments of the present invention is provided for the purpose of explaining to a person of ordinary skill in the art. It is not intended to limit the present invention exclusively to one disclosed embodiment. As described above, those skilled in the art will be familiar with other alternatives and variations of the present invention. For this reason, although some alternative embodiments have been described in detail, those skilled in the art will be able to understand or relatively easily develop to other embodiments. The present invention includes all alternatives, improvements and variations of the present invention described herein and other embodiments that fall within the spirit and scope of the present invention as described above.
