Mattress

Abstract

A mattress includes a plurality of springs, each having two and more attachment fittings for releasably attaching adjacent springs together to form the springs into a spring array, and a top cushion covering the top ends of the springs. By removing the top pad and separating the spring assemblies from each other, the pad can be quickly detached and stored in a compact space.

Description

[0001] This application is a divisional application of the application with application number 201780044305.4, application date June 5, 2017, and invention name “Furniture structure with elastic module or spring module”. Technical Field

[0002] The field of the invention is furniture and mattresses and modules which can be assembled to form furniture cushions or furniture cushions. Background Art

[0003] As cities grow, population mobility accelerates and becomes more frequent. During a move, disassembling and moving large furniture (such as sofas and beds) can be difficult. Large, still usable furniture is sometimes discarded to ease the burden of relocation. Therefore, designing furniture for easy disassembly and / or assembly (e.g., with or without tools) can significantly reduce the energy, time, and financial costs of moving furniture.

[0004] A sofa or bed typically consists of a frame (bedstead or sofa frame), a spring pad (sofa cushion or mattress), and a cover (cloth or leather, etc.). Most spring pads have a traditional, monolithic structure, with multiple overlapping layers and springs forming a single unit. This unitary pad typically includes multiple elastic elements (such as springs) arranged in a generally flat surface, along with various sponge or gel layers that cover the springs to provide comfortable support. Typically, spring pads are non-detachable, monolithic structures.

[0005] So-called "pocket spring" mattresses are designed to prevent two or more people from interfering with each other while lying on the bed (for example, if there is a relatively large difference in weight between the individuals, one person's rolling or shifting would inevitably affect the others). In this type of mattress, each spring is individually packaged in a bag or sleeve made of non-woven fabric or other material. The spring pockets are arranged in a pattern, and then the outer side of the arranged spring pocket group is covered with a single piece of foam rubber by adhesion, gluing, etc. to form the desired spring pad in the form of a furniture pad or furniture cushion. However, the finished spring pad remains a single-piece product. Because the individually packaged spring pockets cannot be separated or removed from the mattress, the mattress remains excessively large, making it difficult to move or store.

[0006] Therefore, there is a need for improved furniture designs, and designs that can be more easily disassembled, moved and reassembled, and more easily stored. Summary of the Invention

[0007] In one aspect, the elastic or spring module comprises at least one spring and an outer covering, and the outer covering is formed by a foam or sponge-type material surrounding the spring. The elastic module can also have an end piece, which is located on the bottom or end surface of the outer covering. If used, the end piece includes a module connection structure for attaching the elastic module to another optional identical elastic module. The end piece can also include a frame connection element for attaching the elastic module to a support frame, for example, a bed frame or sofa frame. The module connection structure and the frame connection element (if used) can preferably be manually attached and removed without using tools. If necessary, or if no end piece is used, the module connection structure and the frame connection element can optionally be attached to the outer covering.

[0008] In a spring module, springs and an outer covering (e.g., outer foam rubber or a similar covering made of, for example, polyurethane) provide comfortable support for the user. A spring pad or mattress constructed from a spring module can be quickly assembled and disassembled, thereby providing furniture that can be more easily moved and stored.

[0009] The outer end surface of the elastic module may have a curvature that conforms to ergonomics, so that when a plurality of elastic modules are assembled into, for example, a sofa, the structure may conform to the back of the human body.

[0010] The module connection structure can be provided on the end member. In one form, it includes a groove in the side wall of the plate of the end member of the first elastic module and a protrusion on the side wall of the plate of the module connection structure of the adjacent second elastic module, wherein the protrusion is configured to engage with the groove. As another example, the module connection structure includes a groove on the outer surface of the end member of the first elastic module and a protrusion on the outer surface of the end member of the adjacent second elastic module, wherein the protrusion is configured to have a shape complementary to the groove. By snapping the groove of the end member of one elastic module into engagement with the complementary protrusion of the end member of the other elastic module, the two elastic modules can be mounted horizontally or vertically. Alternatively, the module connection structure can include mounting holes formed in the body or plate of the end member, which receive separate locking members, thereby allowing multiple elastic modules to be detachably connected together. The end member can be made of metal, plastic, or sponge material.

[0011] On the other hand, the spring can be a coil spring, specifically a cylindrical coil spring, a conical coil spring, a coil spring with a convex or concave center portion, or a coil spring formed by nesting a left-handed spring and a right-handed spring. The outer covering and the spring can be integrally foam-molded within a mold. That is, the spring can be a metal spring, or the spring can be a non-metallic plastic or molded material. Prior to molding, at least one spring can be nested on a core located in the center of the mold. The outer covering can be foam-molded independently of the spring, wherein the center portion is removed to arrange the spring. The outer covering can partially surround the spring. By molding the spring and outer covering together, the spring and outer covering are configured as an integral unit, wherein the spring is made of the molded material.

[0012] In a separate aspect, a mattress includes a plurality of individual spring assemblies, each of which includes at least one conical spring and a spring cap. Each spring cap has at least one first attachment fitting and at least one second attachment fitting, wherein each first attachment fitting can be engaged in or on a second attachment fitting of an adjacent spring cap and can be removed from the second attachment fitting. The spring assemblies can be identical to each other. The spring assemblies are attached to each other via first and second attachment fittings to form the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. Side pads can be positioned around the perimeter of the top pad and / or spring core. By removing the top pad and separating the spring assemblies from each other, the mattress can be quickly and easily assembled and disassembled without tools and stored in a compact space. The springs and spring caps can then form a nested stacked column, wherein the spring column is contained within the spring cap column. Spring clips can be used in place of the spring caps.

[0013] In another aspect, a mattress includes a flat webbing and a plurality of spring caps attachable to the flat webbing. A plurality of springs are provided, each of which is attachable to a spring cap. A top cushion is positioned on top of the springs. The flat webbing may be flexible to allow it to be rolled into a tube or folded, and may be perforated or have a grid pattern of through-holes.

[0014] It will be apparent that elements described in one embodiment may be used alone or in combination in other embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Figure 1a and Figure 1b The figures are a perspective view and a cross-sectional view, respectively, schematically illustrating an elastic module 100. The elastic module 100 includes a spring 5 and an outer cover 1, which is formed of, for example, polyurethane sponge and completely or partially surrounds the spring. The spring 5 is disposed within the outer cover 1 in such a manner that the spring 5 can remain substantially stationary relative to the outer cover 1, thereby allowing the spring and outer cover 1 to move together. The elastic module 100 can be manufactured in at least two ways.

[0070] The first method primarily utilizes the foaming process, where the spring 5 and outer cover 1 are simultaneously and integrally formed. The specific steps are similar to the foaming process for vehicle seats. In short, the spring 5 is nested within a core molded in a mold, such as a foaming box. Because the elastic deformation of the foamed polyurethane sponge is difficult to recover, the elastic force of the spring 5 could be adversely affected. Nesting the spring 5 within the core mold avoids this undesirable possibility. In the first method, the spring 5 and outer cover 1 are integrally formed after the foaming or molding process is complete.

[0071] In the second approach, an outer cover 1 is first manufactured from a polyurethane foam material using a foaming process. The center portion of the foamed outer cover is then hollowed out. The volume of the hollow region can be adjusted based on the number of springs 5 to be included in the elastic module. Next, the springs 5 are placed in the hollow region. To achieve a tight fit between the springs 5 and the outer cover 1, the hollow region should be smaller than the space occupied by the springs 5. In this embodiment, the springs can be attached to the outer cover 1 or simply incorporated into the outer cover 1.

[0072] like Figures 9a-9b As shown, four springs 5 are provided in one outer covering 1, and each spring 5 is preferably separated by a portion of the outer covering 1. In other words, in the first mode of the overall foaming process, the number of cores is preferably equal to the number of springs 5, and in the second mode of forming hollow portions by removing a portion of the foamed body, a portion of the polyurethane foam is preferably retained between each hollow portion, thereby providing a partition wall between adjacent springs.

[0073] In either case, the spring 5 should have a certain preload or pretension after installation or assembly to better achieve a relative static relationship between the spring and the outer cover 1.

[0074] To removably assemble the elastic modules 100, a user can purchase a specific number of elastic modules 100 that fit the desired furniture size, along with a fabric covering, such as a sofa cover or bedspread, that is sized to fit the volume of the specific number of elastic modules 100. The user can then place the elastic modules 100 into the covering, arrange them in a specific pattern, and finally close the covering (via a zipper, snaps, hook-and-loop ties, etc.) to provide a one-piece removable mattress. Ideally, the elastic modules 100 should not move horizontally after being placed into the covering; in other words, the elastic modules 100 should remain in place relative to the covering.

[0075] In order to more firmly combine the multiple elastic modules 100 into a whole, the surface of the outer cover 1 can be provided with a non-permanent connection structure, such as a rope, a snap button, a hook 20, etc., which is, for example, sewn onto the outer cover 1. In this way, a tighter connection is formed between the elastic modules 100, making the sofa, mattress, etc. more comfortable.

[0076] Figures 10a-10d Another example of a plurality of springs being simultaneously arranged within one elastic module 100 is shown. Figure 10a is a top view of the elastic module 10 (or could be a bottom view, depending on how the end piece 2 is arranged relative to the outer cover 1). Figures 10a-10d In the embodiment, six springs 5 of the same size are installed as described above. The size or structure of these six springs can be different. Figure 10b is a side view of an elastic module 100 comprising six springs 5 . Figure 10c and 10d They are respectively a side view and a top view of a spring pad assembled from elastic modules 100 .

[0077] Installing multiple springs 5 within a single elastic module 100 has the following advantages: Compared to a smaller elastic module 100 (e.g., an elastic module 100 having only one spring 5 of the same or similar size), when a user needs to assemble a larger spring mattress, such as a double mattress, this relatively larger multi-spring elastic module 100 facilitates assembly or disassembly, while also saving time. This is because, when spring mattresses have the same or similar volume, the number of elastic modules 100 required is reduced, and the number of assembly or disassembly steps required is also reduced accordingly. Depending on the desired size and characteristics, the elastic module 100 can be provided with, for example, two, four, six, eight, or even more springs.

[0078] Although the elastic module 100 is shown in the figure as a cube or a cuboid, the elastic module 100 can be in a shape such as a triangle or a pyramid, etc. In this case, the number of the springs 5 can be one, three, five, etc.

[0079] Preferably, the spring 5 is a coil spring. Figure 4a The spring 5 shown is a centrally protruding coil spring, as shown in FIG. Figure 4b The spring shown is a concave coil spring, while Figure 4c The spring shown is a truncated conical coil spring. Spring 5 can preferably be any of a cylindrical coil spring, a conical coil spring, a coil spring with a convex or concave center, or a coil spring formed by nesting a left-handed spring and a right-handed spring. In a coil spring formed by nesting a left-handed spring and a right-handed spring, the double spring structure avoids the drawback of a single spring being prone to breakage and can provide improved elastic properties. In practice, any type of spring that can solve this technical problem can be used.

[0080] like Figure 3 As shown, the elastic module 100 can have an end member 2 attached to the lower end of the outer cover 1, wherein the end member 2 is formed with a module connection structure, which can allow multiple elastic modules 100 to be detachably connected to each other. Here, the "upper end face" and the "lower end face" are oriented relative to the longitudinal (vertical) axis of the spring 5.

[0081] In this embodiment, the spring 5 and the outer cover 1 are formed as a single piece as described above. After forming the elastic module 100, the end parts are provided. The bottom end of the spring 5 can be abutted against or attached to the end part 2, i.e., the end part 2 can be used as a support for the spring, such as Figures 4a-4c The end member 2 may be a rigid disc, ring or plate, although in some designs described below, the end member 2 is somewhat flexible.

[0082] exist Figures 7a-7d In the illustrated embodiment, the module connection structure can include a groove 2a formed in one of at least one pair of side walls of the main body of the end member 2, and a protrusion 2b formed on the opposite side wall. The protrusion 2b is adapted to engage the groove 2a of the end member 2 of an adjacent elastic module. The groove 2a and protrusion 2b are attached to each other using a snap fit or a form fit, such as a dovetail fit. Both the groove 2a and protrusion 2b extend horizontally, perpendicular to the longitudinal (vertical) axis of the spring 5. This module connection structure facilitates assembling the elastic modules 100 horizontally, side by side, on a floor or frame.

[0083] In another embodiment, the module connection structure may include a mounting hole 4 formed on the main body of the end member 2, and the mounting hole 4 can cooperate with a separate locking member 3 ( Figure 3 and Figures 7a-7d ), so that multiple elastic modules 100 can be detachably connected together.

[0084] In this case, the mounting holes 4 may be preferably symmetrically distributed on the four corners of the end member 2, as shown in FIG. Figure 3 When two elastic modules 100 are assembled side by side, as shown in FIG. Figure 3 As shown, the locking member 3 is fixed or snapped into the mounting hole 4 using a pin, a screw, etc. or simply by using the locking member 3 itself, thereby connecting the two elastic modules 100. Any number of elastic modules 100 can be assembled horizontally side by side to form a pad or mattress, such as Figure 6 As shown below. Figure 17 The locking member 3 will be described in detail.

[0085] The end piece 2 may have a Figure 2 、 Figure 3 、 Figure 4a-4b The end member 2 can directly contact the ground or the frame, that is, the assembled spring pad can be placed directly on the horizontal contact surface with the end member 2.

[0086] The end member 2 shown in the figure is generally flat or planar, but it can also be in the form of a frame or any other suitable shape, as long as it can perform the function of connecting to another elastic module. In order to be used on the frame, the end member 2 can have a certain flexibility to allow the spring pads 100a, 100b (for example, Figures 15a-15b Mattress and Figures 16a-16b The bottom coil 18 of the spring 5 can rest on or be attached to the end piece 2.

[0087] like Figure 8a and 9b As shown, in addition to the horizontal (or horizontal) components, the elastic modules 100 can also be stacked or assembled vertically. For example, small elastic modules 100 can be constructed horizontally and vertically to provide a cushion or mattress with a desired height.

[0088] The end members 2 may be provided on the top and bottom surfaces of the outer covering. In this case, the module connection structure may include an outer end surface 1a ( Figures 4a-4c ) and the groove formed on the outer end face 1b ( Figure 3), wherein both the groove and the protrusion extend substantially vertically. By engaging the groove on the outer end face of the end member 2 of one elastic module 100 with the corresponding protrusion on the outer end face of the end member of another elastic module, the two elastic modules can be vertically mounted or stacked. In this embodiment, the groove and protrusion used to form the module connection structure are similar to those shown in FIG. Figures 7a-7d The grooves 2a and protrusions 2b shown are similar.

[0089] End pieces 2 can be made of polyurethane sponge, or metal or plastic. Preferably, if used, the sponge used to make end pieces 2 is denser and harder than outer cover 1, so that the end pieces form a sufficiently strong and rigid connection to allow the end pieces of adjacent resilient modules to securely form a spring pad or mattress. In this case, the grooves 2a and protrusions 2b of the module connection structure are formed of polyurethane sponge.

[0090] Now go to Figures 11a-11b , Figures 12a-12b and Figures 13a-13b , the surface of the outer cover 1 can be formed with uniformly distributed concave holes 6. Figures 11a-11b Elongated rectangular holes 6 are shown extending vertically on the side of the elastic module. Figures 12a-12b Horizontally oriented recesses 6 are shown on the side of the elastic module. Figures 13a-13b The honeycomb-shaped recessed holes 6, which are optionally located on all sides of the elastic module, are shown. If used, the recessed holes 6 will reduce the restriction of the outer cover 1 on the movement of the spring 5 in each direction, thereby optimizing the elastic performance of the spring 5 and providing better comfort for the user.

[0091] See also Figure 14 , which shows the storage state of the elastic modules 100, which are not assembled or disassembled. The figure shows the individual elastic modules 100 in a compressed state within the storage space or container 8, significantly reducing the storage space occupied by the elastic modules. When the consumer purchases the elastic modules 100, they can be packaged in a compressed state. This makes it easy to load them into a vehicle and transport them to the consumer's residence. When removed from the container 8, the elastic modules 100 expand. They can then be assembled together without tools. Similarly, following the reverse process, the elastic modules can be temporarily disassembled and stored, or moved from one location to another. Each elastic module 100 can be separated from adjacent elastic modules, compressed, and stored in the container 8. Compared to traditional furniture, the volume of the compressed elastic modules can be advantageously reduced by 40-90%, thereby reducing transportation costs and storage space requirements.

[0092] Also provided are spring pads or mattresses 100a, 100b formed from elastic modules 100. The elastic module 100 may include an elastic outer cover 1 formed from polyurethane sofa foam, at least one spring 5 disposed in the center of the outer cover 1, an end member 2 attached to at least one end surface of the outer cover 1, and mounting holes 4 formed in the body of the end member 2. Preferably, the spring pad further includes a separate locking member 3, which may be connected to the mounting hole 4 via, for example, a screw, or may engage the mounting hole 4 in any suitable manner, allowing multiple elastic modules 100 to be detachably connected to one another.

[0093] A cloth, fabric or leather covering may be provided around the outer cover 1 .

[0094] See also Figures 15a-15d and 16a-16b, which illustrate specific applications of the spring pads 100a, 100b.

[0095] Figures 15a-15d A furniture pad 100a formed from a resilient module 100 is schematically shown. The resilient module 100 can be placed directly flat on, for example, the floor, with the end member 2 located at the bottom of the resilient module 100 on the floor, or it can be attached to a bed frame 100a1 using frame connection elements 100a2, such as clips, paper clips, straps, etc. The dimensions of the assembled resilient module 100 are adapted to match the bed frame 100a1. Figure 15a The assembly process of the spring pad 100a and the bed frame 100a1 is schematically shown. Figure 15b The spring washer 100a is shown after assembly, and Figure 15c and 15d 1 and 2 are side and top views of the spring washer 100a, respectively.

[0096] Figures 16a-16b A spring pad 100b formed from an elastic module 100 is schematically shown, serving as a sofa cushion. As described above, the elastic module 100 can be placed directly flat on, for example, a floor, via the end member 2 at the bottom of the elastic module 100, or it can be attached to a sofa frame 100b1 using a frame connecting element 100b2. Here, the dimensions of the assembled spring pad 100b are adaptively matched to the sofa frame 100b1. Figure 16a Schematically illustrates the assembly process of an exemplary sofa cushion 100b and a sofa frame 100b1, and Figure 16b A perspective view schematically shows a sofa assembled from spring mattresses 100b.

[0097] In order to provide furniture with a slightly curved backrest, such as a sofa, the end member 2 may preferably be made of an elastic material such as rubber, so that it has a certain flexibility. Preferably, the end member 2 may be a relatively thin plastic sheet. Figure 16bIn this case, spring pad 100b uses flexible end pieces 2. The elastic outer cover 1 can be assembled almost seamlessly with the backrest portion of frame 100b1, providing a more comfortable sitting and lying experience for the user. In other embodiments, end pieces 2 are rigid.

[0098] The elastic modules 100 may have the same or different sizes and shapes. The elastic modules 100 do not need to be identical to each other, as long as they can be assembled together as described above.

[0099] like Figure 17 As shown, the spring pad assembled from the elastic modules 100 can be folded to form a Figure 17 The sofa structure shown. In order to allow folding, first, the elastic modules 100 are connected into a row with the desired width of the spring pad 100c. Then, based on the desired length or height, multiple rows are assembled and attached together to form, for example, a backrest portion and a seat cushion portion. In this example where the backrest portion has four rows and the seat cushion portion also has four rows, the four rows of elastic modules on the back are connected to each other via the module connection structure as described above, and the four rows of elastic modules on the seat cushion are also connected to each other via the module connection structure as described above. Finally, it is preferred to use a hinged connection between the elastic modules to join the backrest portion and the seat cushion portion, or any other connection that allows the backrest portion and the seat cushion portion to pivot relative to each other can be used. Of course, other folding connections can also be used.

[0100] Now go to Figure 18 , multiple elastic modules 100 are connected by clips 100b2 or similar frame connecting elements 100a2 ( Figures 15a-15b and Figure 16a ) is mounted to the support frame 7, so that the elastic module 100 is detachably connected to the support frame 7 and remains relatively fixed in place on the support frame. Alternatively, the clip can be arranged in the center or edge of the end member 2, or a plurality of clips can be symmetrically arranged at the four corners of the end member 2. When the elastic module 100 is to be mounted on the support frame 7, the user only needs to, for example, snap or attach the clip to the frame rod of the support frame 7 (for example, Figure 19 7c in, and Figure 15a The frame bars 100a3 and Figure 16a Frame rod 100b3) in to complete the connection.

[0101] exist Figure 18As described above, the elastic modules 100 may include a module connection structure for detachably connecting the elastic modules. In this way, each elastic module 100 can be mounted on the support frame 7 and also connected to an adjacent elastic module. Alternatively, the connection between adjacent elastic modules 100 can be omitted, and each elastic module can be directly mounted on the support frame 7 via the clips 2 c without connecting the modules 100 to each other.

[0102] Figure 19 An example of a clip 2c and a locking member 3 is shown schematically. The frame rod 7c is part of the support frame 7. The clip 2c in the example shown has a semi-cylindrical hollow portion forming opposing flexure arms to clamp or clip onto the frame rod or tube 7c. The clip 2c also has a sheet or plate portion connected to the semi-cylindrical hollow portion for engaging with the locking member 3. The semi-cylindrical hollow portion has an opening adapted to clamp onto the frame rod 7c. The sheet portion may have four protrusions. The locking member 3 may have a plurality of protrusions along the longitudinal axis. Figure 19 The dotted line in FIG. 1 is a blind hole protruding upward, and each locking piece 3 is formed with two such parts.

[0103] During assembly, each of the two blind holes of the locking element 3 is aligned with and engaged with a protrusion on the tab portion of the clip 2 c, for example, using a removable interference fit. The tab portion can be connected to two locking elements 3 at the same time, and the blind hole-shaped portion of the locking element 3 can be inserted into the mounting hole 4 in the end piece 2 to allow the two elastic modules to be engaged with each other.

[0104] also, Figures 15a-15b The frame connecting element 100a2 and Figure 16a The frame connecting element 100b2 in can have the same or similar construction as the clip 2c.

[0105] exist Figure 18 In the case where the elastic module 100 has the end part 2 only on one end face thereof, the other end face of the elastic module 100 opposite to the end face provided with the end part 2 may have a curvature 100d1 determined based on ergonomics, such as Figure 18 This ergonomic curvature enables a contact surface matching the back structure of the human body to be formed immediately after the multiple elastic modules 100 are assembled, thereby making the user feel comfortable.

[0106] Figures 20a-20c is a schematic diagram of another embodiment, which shows that the spring 5 is partially covered by the outer cover 1, and the elastic module 100 is assembled by the groove 2a and the protrusion 2b to form an integral spring pad.

[0107] Figures 21a-21dis a schematic diagram of another embodiment showing that the spring 5 is partially covered by the outer cover 1 and the elastic module 100 is assembled by the module connection structure shown herein to form a furniture pad or mattress. Figures 20a-20c The difference is that the modular connection structure includes protruding ridges or hooks 3a, 3b formed on opposite edges of the end member 2. In this embodiment, one outer layer covers a plurality of springs at the same time, for example, four springs 5 as shown in the drawings.

[0108] Decorative or protective fabric covers or the like may be used on the exterior surface covering of a sofa or bed assembled from the elastic modules 100 .

[0109] The elastic modules enable independent configurations tailored to the user's needs. The modules can be assembled to form furniture, where the vertical deflection of one module has little or no effect on the other modules of the box spring or mattress. The independent configuration also facilitates cleaning and replacement of the modules. Specifically, if a box spring module becomes soiled or damaged, it can be easily replaced without replacing the entire box spring.

[0110] like Figure 22 and 23 As shown, the mattress 130 has a spring core 132, which is composed of individual spring assemblies 145 attached to each other. Each spring assembly includes at least one spring 134 and a spring cap 144. A top pad 136 is placed on top of the spring core 132. Side pads 138 are provided around the perimeter of the spring core. The top pad 136 and side pads 138 can be a foam material, typically 2-8 cm thick. In the example shown, four individual side pads 138 are used. However, a single side pad 138 wrapped around the corners of the spring core 132 and / or top pad 136 can also be used. The side pads 138 on one or more sides of the mattress can optionally be omitted depending on its intended use. As shown in FIG. Figure 22 and 23 As shown, mattress 130 has no rigid frame or side pieces, each spring assembly can be individually attached to an adjacent spring assembly, and the springs themselves are attached to the spring caps rather than being connected to each other. Similarly, the mattress does not require internal ribs, straps or other structures to attach the springs.

[0111] The side pads 138 may be provided by adhesives, fasteners, Hook and loop straps or their equivalent are attached to the top pad 136. A cloth or fabric cover 140 is generally provided over the top pad 136 and the side pads 138. The cover 140 may also optionally cover the bottom of the mattress. Figure 23 As shown, a zipper 142 may be provided on the cover 140 at the periphery of the top cushion 136 to better facilitate installation and removal of the cover. Figure 23 As shown, the spring cap can rest on the floor.

[0112] The spring 134 can be metal, for example, a steel coil spring typically having a single helix, although multiple helices may be used in some embodiments. The spring 134 is conical, tapering from a larger diameter bottom coil 160 to a smaller diameter top coil 58. The bottom coil can have a diameter of 5-15 cm, with the top coil typically having a diameter of 30-90% or 45-70% of the bottom coil. In most designs, the spring 134 tapers uniformly and all springs are identical.

[0113] See also for now Figure 28 and 29 The number of spring assemblies 145 used will vary depending on the size and firmness of the mattress. The mattress shown may have 11 rows and 6 columns of spring assemblies 145. The spring assemblies may be as follows: Figure 28 A rectangular array as shown, or Figure 29 The spring assemblies are shown in a tighter diamond pattern. Any of the types of spring assemblies or elastic modules shown in Figures 1-21 can also be arranged in a triangular pattern, a rectangular pattern, or a hexagonal pattern.

[0114] like Figure 28 As shown, each inner spring assembly 145 (excluding the corners) is attached to four other adjacent spring assemblies, and in Figure 29 In , each inner spring assembly is attached to six other adjacent spring assemblies. Accordingly, in Figure 28 Each outer or peripheral spring assembly 145 is attached to three other adjacent spring assemblies, and in Figure 29 In the embodiment of the present invention, each peripheral spring assembly is attached to four other adjacent spring assemblies. While a standard conventional mattress may have approximately 300 springs, the number of springs in the mattress of the present invention is reduced according to other design features.

[0115] Go to Figure 24A , the bottom coil of the spring 134 is sized to fit within the spring cap 144. The top section 159 of the spring 134 extends through the top coil of the spring, forming the diameter or chord length of the top coil. Each spring cap 144 is generally annular, with a large circular central opening in the body 149 of the spring cap. Figure 25 A portion of the spring core 132 is shown formed by attaching the spring caps 144 to one another.

[0116] Figure 24BAn alternative design is shown in which a spring clip 146 is used in place of the spring cap 144 to attach the springs together to form the spring core 132. The spring clip 146 can be provided as a metal or plastic block having a first slot 147 and a second slot 148. The bottom coil 160 of the spring 134 is placed in the first slot 147, and the bottom coil of the adjacent spring is placed in the second slot 148. The bottom coil 160 can optionally snap into the slot. In some designs, one or more spring clips 146 can be permanently attached to the spring 134. Alternatively, the spring clip 146 can be provided and installed separately as needed. Figure 26 and 28 As shown, if spring clips 146 are used, four spring clips 146 are generally used to attach each spring 134 to four adjacent springs. Of course, various other forms of spring clips 146 may also be used, as any device that can secure the springs together may be used as a spring clip 146.

[0117] See also Figure 27A , the mattress 130 may use a spring cap 150 attached to a webbing or backing sheet 154. Figure 27A In the example of , the webbing is provided as a grid having equally spaced through holes. The webbing 154 may be a thin, flexible material so that it can be rolled up or folded when the mattress is not in use. Alternatively, the webbing 154 may be a rigid sheet. Figure 27A In the illustrated embodiment, spring cap 150 is permanently attached to webbing 154, though in other designs, the cap is removable from webbing 154. Spring cap 150 has an elongated, flat base 152 with first and second curved portions 151 and 155 protruding from base 152. Curved portions 151 and 155 can each have an inward-facing slot 153, or each have an outward-facing slot 157. The slots are adapted to receive and retain the bottom coil of spring 134. If the slots are all inward-facing, the bottom coil of the spring is first compressed and pushed into the slots, then released to expand radially outward into the inward-facing slots. If the slots are all outward-facing, the bottom coil of the spring is first expanded, resting on the curved portions, then released to compress inward into the outward-facing slots. In the illustrated design, all spring caps 150 are aligned parallel to one another and at an acute angle (e.g., 35-55°) relative to the rows and columns of webbing 154.

[0118] Figure 27B A similar design is shown using solid webbing 56 without through holes. Figure 27B The spring cap 161 has spaced apart lugs 162 on the flat base 152, each lug having an outwardly facing slot 163 thereon. Figure 27B The design can be used with Figure 27A The components are assembled and used in the same manner as described above. When the spring caps 150 and 161 are attached (removably or permanently) to the Figure 27A and 27BWhen the webbing 154 and 156 are shown, the spring caps are not attached to each other, as shown. Figure 22-29 shown.

[0119] Figure 27C An alternative design for webbing 60 is shown, including a pattern of pockets or channels 61. The diameter of pocket 61 matches the diameter of the bottom coil of spring 134. Pocket 61 forms an arc of approximately 220-330 degrees. Pocket 61 has an open end 62 and a closed end 63, though in some embodiments, pocket 61 may have two open ends 63. Pocket 61 may be sewn together using two layers of webbing material. Spring 134 is installed on webbing 60 by inserting the free front end 64 of the bottom coil of the spring into the open end 62 of the pocket and rotating the spring 134 clockwise, typically about ¾ of a turn, until it is fully installed, optionally resting against the closed end 63 of the pocket 61. The spring 134 is then attached to webbing 60. Removing the spring 134 in the reverse order provides a quick and easy method for assembling the spring core. With the spring removed, webbing 60 can be rolled up or folded into a compact form. Figure 27D Several springs are shown for use with webbing 60, including Figure 27C The pattern of pockets or channels 61 shown are stacked together.

[0120] like Figure 30B As shown, the alternative spring cap 164 has a generally hexagonal shape, wherein a coil base plate 165 abuts a coil wall 166 on the top side of the spring cap. Inward tabs 167 extend radially inward on the coil base plate 165 to help retain the bottom coil 160 of the spring 134 on the spring cap 164. The diameter of the coil wall 166 and the circular opening through the spring cap 164 defined by the coil base plate 165 will vary depending on the specific spring being used, with typical diameters ranging from 5 to 15 cm. The inward tabs 167 can be provided on only one side of the coil base plate 165 to allow the spring 134 to be more easily installed on the spring cap 164. Side tabs 168 and side slots 169 can be alternately provided on the sides of the spring cap 164. Each side tab 168 is sized to fit into a side slot 169 of an adjacent or adjacent spring cap 164.

[0121] The spring cap 164 may also have side posts 178 that project radially outward from a vertex or corner between two sides of the spring cap 164. Corresponding side sockets or grooves 180 are disposed opposite the side posts 178. The side posts 178 are sized to fit within grooves in adjacent or abutting spring caps 164. The spring cap 164 is flat, approximately 3-15 mm in height, and is made of metal or plastic. Figure 30A The spring core 132 is shown formed of a spring assembly 145 having a Figure 30BThe spring cap 164 is shown. The side posts 178 (if used) help to keep the spring cap 164 in a flat plane when assembled into the spring core 132. Except for the side tabs 168 and the side slots 169, the six sides are flat and smooth to allow adjacent spring caps 164 to be assembled tightly to each other, such as Figure 30A shown.

[0122] Go to Figure 31 、 32A and 30B, another spring cap 171 having a hexagonal body, a coil base 165, a coil wall 166, and a tab 167, and is similar in other respects except that it lacks any side posts 178 and includes the features described below. Figure 30B The spring cap 164 is shown. The spring cap 171 has side plates 172 that extend radially outward from adjacent sides of the spring cap 171. A plate hook 173 protrudes upward from the top side of each side plate 172. The height and curvature of the plate hook 173 are selected to correspond to the inner diameter of the bottom coil 160 of the spring 134. Figure 39 As shown and discussed below, alignment holes 177 can be provided through each side plate 172 to better allow alignment of the spring caps 171 into stacked columns. A pair of hooks 174 are provided at the bottom of the spring caps, on the sides of the spring caps 171 opposite the side plates, adjacent the corners of the spring caps 171. A pair of notches 176 are provided on opposite sides of each side plate 172, wherein the notches 176 are configured to engage with the hooks 174 of the adjacent spring caps 171.

[0123] Figure 31 166 . The spring cap 171 is a bottom view of the spring core 32 formed by the spring 134 and the spring cap 171. The bottom coil 160 of the spring 134 is retained in the spring cap 171 between the coil tabs 167 and the coil base plate 165. If the spring 134 is rotated slightly when pressed onto the spring cap 171, the bottom coil 160 may temporarily shrink slightly during installation and then return to its original diameter. In this case, friction may also help to hold the bottom coil 160 in place by the radially outward spring force holding the bottom coil 160 against the coil wall 166. The plate hooks 173 engage the inner surface of the corresponding section of the opening of the spring cap adjacent the spring assembly, for example, at Figure 32B The hook 174 engages with the notch 176 of the adjacent spring cap 171. Figure 32B As shown, a bevel 175 on the top of the spring cap 171 that is aligned with the notch 176 can be used to guide the loop hook 174 into the notch 176. Due to their design and size, the loop hook 174 and the plate hook 173 have a limited amount of elasticity or flexibility, and are also optionally caused by the elastic properties of the material (such as plastic material) used to make the spring cap 171. During the assembly process of the spring core, the plate hook 173 and the loop hook 174 can snap into place.

[0124] See also Figure 33B , the other spring cap 184B has the coil base 165, coil wall 166, and coil tab 167 as described above. The spring cap 184B may also have a spring end socket 185 to hold the end of the wire of the spring 134. A pair of cotter pins 186 protrude outwardly from a boss 188 on a first side of the spring cap 184B. A corresponding pair of pin holes 187 extend through the boss 188 on a second side of the spring cap 184B opposite the first side, wherein the pin holes 187 are aligned with the cotter pins 186. The outer end of each cotter pin 186 may be tapered or angled. Figure 33A A portion of the spring core 132 formed by the spring 134 and the spring cap 184A is shown. The spring cap 184A is identical to the spring cap 184B but further includes corner tabs 190. The corner tabs 190, if used, can help the spring cap 184A rest flat on the base plate. As described below, the corner tabs 190 can also strengthen the spring cap 184A to prevent twisting and bending, and also help keep the spring cap 184A aligned when stacked into a column for storage.

[0125] like Figure 33A and 33B As shown, the spring core 132 is formed by installing a spring 134 in each spring cap 184A (or 184B). Then, the spring caps 184A are attached to each other by pushing the cotter pin 86 into the pin hole 187 of the adjacent spring cap 184A. Each cotter pin 86 can have a plurality of flexible arms 191, which bend inwardly as the cotter pin enters the pin hole 187 and then returns to the initial position, thereby tending to firmly hold the adjacent spring caps 184A together. In an alternative method, the spring caps 184A can first be attached to each other, and then the spring 134 is subsequently installed in each spring cap 184A.

[0126] Return to see Figure 24B , the ends of most springs 134 terminate in end windings 135 where the wire forming the spring is wound around itself. When the spring is installed in the spring cap, the spring can be rotated until the bottom end winding 135 abuts against a stop surface, such as boss 188. In this way, all springs 134 in the spring core 132 will have the same orientation, e.g., Figure 33A As shown, all top sections 159 of the springs 134 are parallel to each other, and the mattress 130 can have a more consistent firmness. For springs without bottom windings 135, the bottom ends of the spring wires can be bent into vertical sections and inserted into the spring end sockets 185 (if used).

[0127] Now see Figure 34BAnother spring cap 194 may be identical to spring cap 184A, except that corner tabs 190 are located at the top of the spring cap rather than the bottom, and the corner tabs 190 are provided as part of a side frame 195 on opposite sides of the spring cap 194. In addition, the spring cap 194 has a modified cotter pin 196 and a pin hole 199 extending through a boss 197. A flexible tab 198 is pivotally attached to each boss 197. The flexible tab has a collar 201 adapted to surround the cotter pin 196 adjacent the spring cap 194. When the flexible tab 198 is pivoted downward to the closed position, a latch hook 202 on the bottom surface of the flexible tab 198 engages a lip 203 on the boss 197.

[0128] like Figure 34A and 34B As shown, the spring core 132 is formed by installing the spring 134 in the spring cap 194. The spring caps 194 are then connected to each other by inserting the cotter pin 196 of the first spring cap 194 into the pin hole 199 of the second adjacent spring cap 194, wherein the flexible tab 198 is in the Figure 34A and 34B 197 . The spring cap 194 is then pulled upwardly and into the open position as shown. The flexible tab 198 is then pivoted to the downward or closed position. The latch hook 202 engages in or on a lip that holds the flexible tab 198 in the downward position. The collar 201 prevents the cotter pin 196 from being withdrawn from the pin hole 199. Thus, the spring cap 194 cannot be accidentally detached when the mattress is in use. To disassemble the mattress 130, the flexible tab 198 is pulled upwardly and into the open position. This allows the cotter pin to move out of the pin hole 199, thereby allowing the spring cap 194 to be detached. If the spring cap 194 is molded from a plastic material, the flexible tab 198 can be attached to the boss 197 by a so-called living hinge. Of course, a solid pin could be used in place of the cotter pin.

[0129] like Figure 34B As shown, the cotter pin 196 is aligned with the pin hole 199, that is, on each side of the spring cap, a single centerline on the chord 193 of the circular opening of the spring cap passes through both the cotter pin and the pin hole at the center. In addition, the chord 193 is located at a distance D2 from the center line 192 of the spring cap, where D2 is equal to one-quarter of the width D1 of the spring cap. Therefore, when assembled as shown Figure 33A 、 34A 35A, each row of spring assemblies 145 is offset from the adjacent row by half the width of the spring cap.

[0130] Now see Figure 35A 、 35B and 35C, another spring cap 204 can be connected with Figure 33BThe illustrated spring cap 184B is identical but further includes a corner frame 207 adjacent to each boss having a cotter pin 196. On the opposite side, a pin hole 187 extends through the cotter boss 206. A release tab 205 is attached to the outer half of each cotter boss 206. A spring core 132 using spring caps 204 can be assembled by installing the springs 134 in the spring caps 204 and then connecting the spring caps 204 to each other by inserting the cotter pins 196 into the pin holes 187. The cotter bosses 206 can be resiliently and momentarily moved apart to allow the heads of the cotter pins 196 to pass through the pin holes 187. The cotter pins 196 cannot then be withdrawn without pressing the release tabs 205. This prevents the spring caps 204 from accidentally detaching while the mattress is in use. In some cases, it may be easier to assemble the spring caps 204 before installing the springs.

[0131] like Figure 36A and 36B As shown, a protrusion or boss 220 can be provided on the bottom surface of the top mattress 136, wherein the top coil of each spring surrounds the boss. This can help keep the springs 134 aligned and upright when the mattress 130 is in use. The boss 220 can be D-shaped to better secure the top ends of the springs 134, wherein the top sections 159 of the springs 134 rest against the straight sides of the boss.

[0132] like Figure 37A and 37B As shown, each boss 220 can be disposed within a recess 222 in the bottom surface of the top pad 136 to further prevent accidental displacement of the top end 158 of the spring 134. The bosses 220, if used, can be the same material as the top pad 136 or can be a separate component adhered to the top pad.

[0133] like Figure 38 、 39 As shown in FIG40, because the spring caps can be separated from each other and from the spring 134, and because the spring has a taper, the spring 134 and the spring caps can be stacked into a compact column for easy storage and transportation. Figure 38 As shown, the springs 134 can be nested within each other to form a compact spring column 232. The spring cap can then be formed into a spring cap column 234 that is placed above or around the spring column 232, as shown. Figure 39 As shown. Cup 230 can be placed on the top of spring column 232. Spring cap column 234 including spring column 232 can be placed in a compact container 236 for easy transportation or storage. Top cushion 136 and side cushion 138 can be stored as is, or can be rolled, folded or compressed. Thus, mattress 130 can be transported and stored with minimal space. If spring cap is provided as shown Figure 32A The alignment hole 177 is shown, and a rod can be inserted through the alignment hole to help keep the spring cap aligned into the column.

[0134] In this design, when a mattress is used, each spring in the spring core is independently stressed, allowing it to deflect significantly independently of adjacent springs. The springs can expand and contract individually according to the body's contours. As a result, the mattress can evenly and appropriately support the varying weights of people in different positions. This helps keep the sleeper's spine straight and flat, providing a more comfortable night's sleep. When force is applied to one area, other areas remain stationary. If one sleeper tosses and twists, another sleeper on the mattress remains unaffected. Conical springs with smaller-diameter top coils and larger-diameter bottom coils stabilize spring deformation when force is applied diagonally, reducing or preventing side-to-side wiggling or noise caused by spring friction.

[0135] The springs can be arranged in a rectangular shape, e.g. Figure 26 and 28 As shown, or arranged in a diamond shape, such as Figure 29 shown. Figure 29 The diamond arrangement can effectively improve the spring coverage, reduce the spring gap, and enhance the comfort of the mattress.

[0136] The mattress of the present invention has a simple structure that allows quick and easy assembly and disassembly of the mattress. The mattress can be easily cleaned and washed, not only the cover 140 but also the springs 134 can be cleaned, and the mattress can be regularly hung in the sun for cleaning and ventilation.

[0137] During transport and storage, the springs can be stacked on top of each other for efficient packaging, and soft structures such as the top and side cushions can be compressed, folded, or packed, significantly reducing storage space requirements. The mattress can be loaded in a vehicle, allowing people to enjoy a home-style spring mattress outdoors.

[0138] Because the springs have a very long life, they can be reused when the cover 140 needs to be replaced. Alternatively, one set of springs can be matched with multiple sets of cover materials in use. When the mattress is damaged and needs to be disposed of or recycled, the process is simple and inexpensive due to the removable structure of the mattress.

[0139] like Figures 41-44 As shown, an upper annular plastic part 302 and a lower annular plastic part 303 are provided, wherein a positioning shaft 304 is provided on the upper end face and the lower end face of the upper annular part and can be engaged with a positioning hole 307 formed on the lower annular part. After the spring 305 is installed in the lower annular plastic part, the upper ring is locked with the lower annular part by the positioning shaft 304, and then the spring is as shown in FIG. Figure 42 After each set of plastic parts and springs are assembled together, they can be reliably stacked on top of each other through the positioning shaft and positioning hole, as shown. Figure 43As shown, to provide a conical spring stack, wherein D1 is greater than or equal to D0+2*n*d, wherein D1 represents the larger diameter of the spring, D0 represents the smaller diameter of the spring, n represents the number of coils of the spring, and d represents the wire diameter of the spring. The connection design is as follows Figure 44 As shown. Figures 41-44 The design shown may be used in a resilient module or spring assembly to provide the pads and mattresses described above with respect to Figures 1-40.

[0140] Go to Figures 45-49 , the spring mattress is divided into a plurality of independent rising and falling parts or blocks 306, such as Figure 48 As shown in Sections 1-9 of FIG. Each block can be driven by a motion mechanism 308 to rise and fall independently, or connected together for controlled movement. This spring mattress can be used in functional beds, functional sofas, health beds, functional mattresses, and the like. The rising and falling blocks can be used to achieve the desired functions of a functional bed, etc., and can achieve purposes such as improving human comfort, stopping snoring, providing zero gravity, stretching, and pressing. Simple massage can also be provided by rapidly moving the lifting mechanism via electronic control.

[0141] Each group includes at least one spring, which can be a conical coil spring, a cylindrical coil spring, a convex coil spring or a concave coil spring. A sponge structure 310 is attached to the top of the spring, and a mounting base 312 is provided at the bottom of the spring. Figures 45-47 As shown, the base can be driven by at least one drive mechanism 308 (such as a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder) to achieve the raising and lowering of the spring group. Alternatively, the raising and lowering of the spring group can be achieved by the cooperation of a motor and a cam or an eccentric bearing, or by the inflation and deflation of an air bag installed below the spring base.

[0142] like Figure 48 and 49 As shown, the sections 1-9 can be regularly or irregularly distributed, and each block can be moved vertically independently of the other blocks. Figure 51 As shown, different masses may have different numbers of spring assemblies and actuators.

[0143] exist Figure 52 and 54 In the embodiment of the invention, the cover 311 of the entire spring mattress can be made of a flat and smooth fabric or material, or the cover material can be formed into a block-like protrusion, and the sponge on top of the springs can be partially recessed, so that when the individual spring groups rise and fall, the entire mattress looks natural and attractive. The fabric can be elastic. The fabric can be pre-formed with pleats 313, which are configured to fit between adjacent parts, such as Figure 50 As shown. Figure 53 As shown, a foam or quilted top layer 314 may be provided on top of sections 1-9.

[0144] exist Figures 52-54 In the mattress, gaps can be provided between adjacent blocks so that proper lifting of the blocks can maximize the contact area of the human body lying on the mattress, and the mattress keeps the spine in a horizontal state, thereby achieving the best sleeping experience.

[0145] The movement and positioning of the spring block can be controlled by electrical signal control or APP application control. If the lifting frequency of the block is increased, a vibration or impact massage effect can be achieved.

[0146] like Figure 54 As shown, by controlling each spring block to rise and fall appropriately, the zero gravity function of the mattress can be achieved, wherein the user's legs are raised to a position above the heart level, and the back and legs form an angle of 126±7 degrees. Additionally, the circulation and repeated lifting of the blocks enable the mattress to press and stretch the human body, thereby relaxing the user and reducing fatigue. Appropriate sensors and control systems can be used in conjunction. When a sleeper snores during sleep, the spring blocks near the neck and head are lifted to an inclined angle (about 15 degrees) to reduce or stop snoring. Similarly, Figure 54 As shown, the actuator is pivotally attached to portion 1-9.

[0147] The control system can store the lifting position of each spring block in a memory, thereby realizing multiple memory modes. When each spring block is adjusted to the appropriate position for the first time, it can be quickly adjusted to the most comfortable position from this point on.

[0148] The structure in which the spring group is raised and lowered in blocks can also be applied to medical beds and sofas or benches for daily use, and can be coordinated with an intelligent control system to realize functional and intelligent medical beds and sofas.

[0149] In each of the above-described embodiments, the elastic modules or spring assemblies can be attached to one another using only the described modular connection structure, eliminating the need for separate transverse or longitudinal sofa or bed frame slats or structural elements or connecting strips. A perimeter frame surrounding the perimeter of the box spring or mattress constructed from the elastic modules or spring assemblies can optionally be used to provide an improved appearance and further secure these components in place. No base or tray is required beneath the elastic modules or spring assemblies to support or secure them in place.

[0150] Typically, a spring pad or mattress can be assembled with end pieces 2 or spring caps placed edge to edge, touching each other with no spaces or gaps in between. Each end piece or spring cap is generally directly attached to four adjacent end pieces or spring caps, except at corners and edges, where each end piece or spring cap is attached to two or three other end pieces or spring caps. The described spring pads and mattresses typically have no rigid or hard elements on the top, thus providing a comfortable support surface for the user. Specifically, the top of the elastic module may consist solely of an outer covering made of a soft foam material, which may have low thermal conductivity to act as an insulator.

[0151] As described above, the elastic module and the spring assembly can be assembled without any intermediate elements, such as any walls or partitions. The elastic module and the spring assembly can be configured as substantially simple mechanical elements without any electrical components or wiring.

[0152] Of course, various changes and substitutions can be made without departing from the spirit and scope of the present invention. This description and examples are to be considered illustrative, and the true scope of the present invention is defined by the appended claims and their equivalents. Therefore, the present invention should not be limited except in accordance with the claims and their equivalents.
