Description

Technical Field

[0001] This disclosure relates to the furniture industry, and in particular to resilient pads and their resilient modules and components used in furniture such as beds or sofas. Background Technology

[0002] To improve sitting or lying comfort, furniture such as beds and sofas often incorporate resilient cushions. Various types of resilient cushions, such as foam cushions and spring cushions, are already available in the technology. Traditional resilient cushions are usually one-piece units, making them inconvenient to move. Therefore, there is a demand for resilient cushions that are easy for users to assemble themselves.

[0003] For spring pads, various solutions have been proposed in the existing technology to improve their comfort, such as spring pads composed of individually pocketed springs and spring pads composed of individual spring modules. However, the elastic characteristics that these spring pads can provide are still limited. There is a desire for more elastic pads with different elastic characteristics to choose from. Summary of the Invention

[0004] This disclosure at least partially addresses or mitigates the aforementioned deficiencies in the prior art.

[0005] According to one aspect of this disclosure, an elastic component for an elastic pad is provided. The elastic component includes a first elastic module and a second elastic module extending along the height direction of the elastic pad and capable of elastic deformation along the height direction. In a transverse direction perpendicular to the height direction, one of the first and second elastic modules is an outer elastic module, and the other is an inner elastic module, the outer elastic module surrounding the inner elastic module circumferentially outside the inner elastic module. Along the height direction, the upper end of the first elastic module is higher than the second elastic module, such that when the elastic component is subjected to downward pressure, the first elastic module first directly receives the pressure, and then the second elastic module directly receives the pressure or indirectly receives the downward pressure transmitted by the first elastic module. This disclosure also provides an elastic pad including this elastic component, and furniture including the elastic pad.

[0006] According to another aspect of this disclosure, an elastic component for an elastic pad is provided. The elastic component includes a first elastic module extending along the height direction of the elastic pad and a retaining module for retaining the first elastic module. The retaining module has an upwardly opening receiving space to allow the first elastic module to be inserted downwardly into the receiving space of the retaining module, thereby retaining the first elastic module. With the first elastic module inserted into and held by the receiving space of the retaining module, the upper end of the first elastic module extends upward beyond the receiving space and is higher than the retaining module, such that when the elastic component is subjected to downward pressure, the first elastic module receives the pressure first. This disclosure also provides an elastic pad including this elastic component, and furniture including the elastic pad.

[0007] According to another aspect of this disclosure, an elastic pad is provided. The elastic pad includes a main elastic layer providing a primary source of elasticity. The main elastic layer includes a plurality of elastic components arranged in an array in an extending plane perpendicular to the height direction of the elastic pad. Each elastic component includes a first elastic module and a second elastic module extending along the height direction of the elastic pad and capable of elastic deformation along the height direction, the second elastic module surrounding the first elastic module circumferentially outside the first elastic module. Along the height direction, the upper end of the first elastic module is higher than the second elastic module, such that when the elastic component is subjected to downward pressure from outside the elastic pad, the first elastic module first directly receives the pressure, and then the second elastic module directly receives the pressure or indirectly receives the downward pressure transmitted by the first elastic module. The main elastic layer also includes an interconnected elastic network. The interconnected elastic network extends in a plane perpendicular to the height direction and is located between the upper and lower surfaces of the main elastic layer. The interconnected elastic network is connected to the second elastic modules of at least a portion of the plurality of elastic components for transmitting the pressure and / or elastic deformation between the second elastic modules interconnected by the interconnected elastic network. When any one of the second elastic modules of the at least portion of the elastic components undergoes elastic deformation due to the pressure, the pressure is transmitted via the interconnected elastic network to the other connected second elastic modules so that the pressure is borne collectively by the interconnected second elastic modules. This disclosure also provides furniture including the elastic pad.

[0008] According to another aspect of this disclosure, a retaining module for an elastic pad is provided for retaining a first elastic module and forming therewith an elastic component extending along the height direction of the elastic pad. The retaining module includes a second elastic body capable of elastic deformation along the height direction; and a mounting cylinder supported by the second elastic body. The mounting cylinder is hollow, and its inner surface defines a receiving space for receiving the first elastic module. The receiving space of the mounting cylinder extends along the height direction and opens upward to allow the first elastic module to be inserted downward from above into the receiving space of the mounting cylinder, thereby retaining the first elastic module. Downward or upward movement of the mounting cylinder can correspondingly compress or release the second elastic body. This disclosure also provides an elastic component including the retaining module, an elastic pad including the elastic component, and furniture including the elastic pad.

[0009] According to another aspect of this disclosure, an elastic module for an elastic pad is provided. The elastic module includes: a second elastic body extending along the height direction of the elastic pad and having opposite upper and lower ends, and capable of elastic deformation in the height direction; a flat base surrounding the second elastic body and located between the upper and lower ends in the height direction; and at least one flexible member connected between the second elastic body and the base to allow relative movement of the second elastic body relative to the base along the height direction. This disclosure also provides an elastic assembly including the elastic module, an elastic pad including the elastic assembly, and furniture including the elastic pad.

[0010] According to another aspect of this disclosure, an elastic pad is provided. The elastic pad has an extending plane and a height direction perpendicular to the extending plane. The elastic pad includes a plurality of first elastic modules and a flat base layer within the extending plane. The base layer has an upper surface and a lower surface opposite to the upper surface; and a plurality of retaining recesses arranged in an array on the upper surface, each of the retaining recesses being recessed downward from the upper surface of the base layer. The plurality of first elastic modules extend along the height direction of the elastic pad and are capable of elastic deformation along the height direction. The lower end of each first elastic module is inserted into the recess to be retained by the base layer. The upper end of each first elastic module extends upward and beyond the upper surface of the base layer. This disclosure also provides furniture including this elastic pad.

[0011] The elastic component and the elastic pad formed by the elastic component disclosed herein are easy to assemble. Moreover, in some embodiments, since each elastic component is composed of two elastic modules, a variety of different elastic properties can be exhibited by adjusting the elastic coefficient of each elastic module, the structural changes of each elastic module, and the connection and / or positional relationship between the elastic modules respectively.

[0055] First embodiment:

[0056] Figure 1 and Figure 2 An assembled elastic pad 1000 according to a first embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, the elastic pad 1000 is essentially a flat shape extending in the XY plane and has a height or thickness extending along the Z direction. Typically, the elastic pad 1000 can be applied to a bed or sofa to provide a resilient support surface, so as to provide a comfortable and resilient support for a person sitting or lying on the support surface.

[0057] The elastic pad 1000 may include a primary elastic layer 1100 and a first pad layer 1200 covering the primary elastic layer. The primary elastic layer 1100 may be made of an elastic material and provides the primary source of elasticity for the elastic pad 1000. The first pad layer 1200 may be located above the primary elastic layer 1100 and is closer to the human body than the primary elastic layer 1100 during use. The first pad layer 1200 may generally have a substantially continuous and flat surface to provide a more human-friendly surface for the elastic pad 1000. The first pad layer 1200 may also have a degree of elasticity to provide a secondary source of elasticity for the elastic pad 1000. The first pad layer 1200 may be made of, for example, sponge or silicone, and this also applies to the first pads in subsequent embodiments.

[0058] The main elastic layer 1100 may include a plurality of elastic components 1110 arranged in an array along the XY plane. The structure of the elastic pad 1000 and the elastic components 1110 is as follows: Figure 3 The exploded view shows it more clearly. For example... Figure 3 As shown, each elastic component 1110 in the main elastic layer 1100 may include a first elastic module 1120 and a second elastic module 1130 extending along the height direction Z and capable of elastic deformation along the height direction Z. The first elastic module 1120 can be inserted downward along the height direction Z into and held by the corresponding second elastic module 1130. That is, the second elastic module 1130 can be both an elastic module and a holding module for holding the first elastic module 1120. In the assembled state, the first elastic modules 1120 of each elastic component 1110 can be independent of each other, while the second elastic modules 1130 of adjacent elastic components 1110 can be connected to each other.

[0059] During assembly, the second elastic modules 1130 of each elastic component 1110 can be connected together to form an elastic base layer 1140 that is elastic along the height direction Z, such as... Figure 4 As shown. The elastic base layer 1140 can be located within the extended plane (i.e., the XY plane) of the elastic pad. The elastic base layer 1140 is flat and has an upper surface 1141 and a lower surface 1142 opposite to the upper surface 1141. The elastic base layer 1140 may have a plurality of retaining recesses 1143 arranged in an array on its upper surface, each retaining recess 1143 being recessed downward from the upper surface 1411 of the elastic base layer 1140. As will be clear below, the retaining recesses 1143 can be formed by the receiving space 1135 of the second elastic module 1130 for retaining the corresponding first elastic module 1120. Then, as Figure 5 and Figure 6As shown, the lower end of the first elastic module 1120 of each elastic component 1110 can be inserted from top to bottom into the corresponding second elastic module 1130, that is, into the retaining recess 1143 of the elastic base layer 1140, so as to be held by the second elastic module 1130 or the entire elastic base layer 1140. The upper end of the first elastic module 1120 can extend upward beyond the second elastic module 1130, or beyond the upper surface 1141 of the elastic base layer 1140. For clarity of illustration, Figure 5 The image shows only a portion of the elastic base layer 1140, and exemplarily illustrates several first elastic modules 1120 to be inserted into the corresponding second elastic module 1130. It should be understood that each first elastic module 1120 and its corresponding second elastic module 1130 constitute the aforementioned elastic component 1110 (this is in...). Figure 5 (Schematic representation using a rectangular dashed box 1110). After inserting all the first elastic modules 1120 into their respective second elastic modules 1130, a structure can be formed. Figure 6 The main elastic layer 1100 shown is composed of multiple elastic components 1110 arranged in an array.

[0060] Finally, as Figure 7 As shown, the first pad 1200 can be laid on the main elastic layer 1100 composed of the assembled elastic components 1110 to form... Figure 1 and Figure 2 The assembled elastic pad 1000 is shown.

[0061] Figure 8 and Figure 9 The assembly process of the elastic pad 1000 is shown more clearly in a magnified view. Figure 8 yes Figure 3 The exploded view shows an enlarged view of region B in the side view along the X direction, where the internal structure of the first elastic module 1120 is additionally shown in dashed lines. Again, it needs to be understood that each first elastic module 1120 and its corresponding second elastic module 1130 constitute the aforementioned elastic component 1110 (this is in...). Figure 8 (Illustrated schematically using a rectangular dashed box 1110). For example... Figure 8 As shown, the second elastic module 1130 of each elastic component 1110 is as follows: Figure 4 After connecting them into the elastic base layer 1140 as shown, the first elastic module 1120 of each elastic component 1110 can be inserted downwards into the second elastic module 1130 along the direction indicated by arrow A (that is, the height direction Z mentioned above) to form Figure 1 , Figure 2 , Figure 6 and Figure 7The main elastic layer 1100 is shown in the diagram. Finally, the first pad layer 1200 is laid downwards along the direction indicated by arrow A on top of the main elastic layer 1100, which is composed of multiple elastic components 1110, to form a structure as shown in the diagram. Figure 9 The assembled elastic pad 1000 is shown.

[0062] To define the position of the first pad 1200 relative to the underlying main elastic layer 1100 in the horizontal direction (in the plane containing the X and Y directions), the first pad 1200 may have a plurality of limiting protrusions 1210. See also Figure 8 During assembly, each limiting protrusion 1210 can extend downwards along the direction of arrow A into the interior of a corresponding first elastic module 1120, thereby restricting the horizontal movement of the first pad layer 1200 relative to the main elastic layer 1100. After assembly, as... Figure 9 As shown, the first elastic module 1120 of each elastic component 1110 can be held in place by a corresponding second elastic module 1130, while the first padding layer 1200 can be laid on each elastic component 1110. Specifically, Figure 9 The internal structure of the rightmost elastic component 1110 is also shown by dashed lines. It can be seen that the limiting protrusion 1210 of the first pad 1200 extends into the interior of the first elastic module 1120, thereby defining the relative position of the first pad 1200 with respect to the elastic component 1110 below it.

[0063] To more clearly illustrate the first pad 1200 with the limiting protrusion 1210 Figure 10 The lower surface 1211 of the first padding layer 1200 is shown facing upwards. See also Figure 10 The first pad 1200 may include a flat body 1220. The body 1220 has a lower surface 1221 facing downward in the assembled state. Adjacent to the edge of the body 1220, a plurality of limiting protrusions 1210 extend outward from the lower surface 1221 of the body 1220.

[0064] Figure 11 yes Figure 5An enlarged view of region C more clearly shows the first elastic module 1120 and the second elastic module 1130 of each elastic component 1110. The first elastic module 1120 may be made of an elastic material to provide elastic deformation along the height direction Z. The first elastic module 1120 may generally be conical or frustoconical in shape. In the assembled state, the lateral dimension of the first elastic module 1120 gradually tapers along the height direction Z from the upper end, or enlarging end 1121, to the lower end, or shrinking end 1122, presenting an inverted conical or frustoconical shape. The first elastic module 1120 may be hollow and open outward at its enlarging end 1121, forming an opening 1123. This hollow and conical or frustoconical first elastic module 1120, on the one hand, can provide elastic characteristics that vary with size along the height direction Z, and on the other hand, can facilitate storage and transportation in the unassembled state. Figure 12 As shown, through the opening 1123 of the enlarged end 1122 of the first elastic module 1120, one first elastic module 1120 can be inserted into the interior of another first elastic module 1120, thereby allowing multiple first elastic modules 1120 to be stacked together to reduce storage space.

[0065] See back Figure 8 and Figure 9 The first elastic module 1120 can be in the form of a pocket spring, which is a conical helical spring wrapped in flexible material. Figure 13 It's clearer in the middle. Figure 13 The internal structure of the first elastic module 1120 is shown more clearly. For example... Figure 13As shown, the helical spring 1124, serving as the elastic body, gradually narrows from the enlarged end 1121 to the reduced end 1122 of the first elastic module 1120. The outer and inner surfaces of the first elastic module 1120 can be formed by an outer flexible material layer 1125 and an inner flexible material layer 1126, respectively, and the helical spring 1124 can extend between the outer flexible material layer 1125 and the inner flexible material layer 1126. The outer flexible material layer 1125 and the inner flexible material layer 1126 are interconnected to form a flexible sleeve. The helical spring 1124 can be encapsulated in this flexible sleeve in a certain pre-compressed state (not a completely free state), so that the formed first elastic module 1120 can undergo elastic deformation while also having a certain stiffness. This stiffness of the first elastic module can help maintain the shape of the first elastic module 1120 in a static state and help provide a suitable initial hardness or initial support force for the elastic pad 1000. In other embodiments, the flexible sleeve encapsulating the helical spring 1124 may also be a single layer of flexible material covering the outer surface of the helical spring 1124. In other embodiments, the helical spring 1124 may also be pre-compressed in other ways, such as the flexible strap used in the second elastic module 1130 described below. In some embodiments, the elastic body of the first elastic module may also take the form or material of a different form than the helical spring 1124, such as a sponge or a plurality of vertically extending strip leaf springs arranged circumferentially.

[0066] Figure 14 A second elastic module 1130, which can be applied to the elastic component 1110, is schematically shown. For example... Figure 14 As shown, the second elastic module 1130 may include a helical spring 1133 capable of elastic deformation. The helical spring 1133 can serve as the elastic body of the second elastic module 1130 and is hollow. The helical spring 1133 can be mounted and constrained between the base 1131 and the end cap 1132. The flat base 1131 can be located at the upper end of the second elastic module 1130, and the end cap 1132 can be located at the lower end of the second elastic module 1130. Specifically, the helical spring 1133 may have a helical spring at one end (at... Figure 14 The upper end of the middle section abuts against the base 1131, while the other end (at the upper end) abuts against the base 1131. Figure 14 The lower end of the coil spring 1133 can abut against the end cap 1132. The upper end of the coil spring 1133 can also be connected to the base 1131 by means of, for example, a snap-fit. The abutment or connection between the coil spring 1133 and the base 1131 can be substantially rigid, that is, the movement of the upper end of the base 1131 and the coil spring 1133 in the height direction Z can be synchronous.

[0067] On the outside of the helical spring 1133, multiple flexible straps 1134 extend between the base 1131 and the end cap 1132. By pre-determining the length of the flexible straps 1134, the distance between the base 1131 and the end cap 1132 can be limited, thereby constraining the distance between the upper and lower ends of the helical spring 1133, allowing the helical spring 1134 to be constrained between the base 1131 and the end cap 1132 in a pre-compressed state (not a completely free state). With the aid of the pre-compressed helical spring 1134, the resulting second elastic module 1130 can undergo elastic deformation while also possessing a certain stiffness. This stiffness of the second elastic module 1130 can help maintain its shape in a static state and provide suitable initial stiffness or initial support force when compressed and deformed. In other embodiments, the helical spring 1133 of the second elastic module 1130 may also employ a similar design. Figure 13 The first elastic module 1120 shown is encapsulated and pre-compressed using a pocket spring, and its upper end is then mounted to the base 1131 described above. In appropriate cases, the second elastic module 1130 can also use a non-coil spring elastic body, such as a sponge or leaf spring.

[0068] The base 1131 of the second elastic module 1130 may have a connecting portion 1136 for interconnecting with the base 1131 of other adjacent elastic components 1110 during assembly, to form, for example... Figure 4 The elastic base layer 1140 is shown. For ease of assembly, the bases 1131 of several second elastic modules 1130 can be integrally formed to create a module containing multiple second elastic modules. This way, during assembly, it is not necessary to assemble the second elastic modules one by one; instead, a smaller number of modules can be assembled together. In fact, Figure 4 The second elastic module 1130 in each row along the X direction is such a module.

[0069] The second elastic module 1130 and its helical spring 1133 may be tapered or frustoconical in shape, tapering from the base 1131 to the end cap 1132, and in the assembled state, the tapered or frustoconical shape may be inverted. The second elastic module 1130 may be hollow, and its base 1131 may have an opening 1137, thereby allowing the second elastic module 1130 to have an upwardly opening receiving space 1135. This receiving space 1135 may be defined by the inner surface of the helical spring 1133 and the upper surface of the end cap. Thus, referring to the previous figures, in particular... Figures 8-10This allows the first elastic module 1120 to be inserted from top to bottom into the receiving space 1135 of the second elastic module 1130, thereby allowing the second elastic module 1130 to hold the first elastic module 1120, forming an assembled elastic assembly 1110. The receiving space 1135 can also be an inverted cone or frustoconical shape that tapers from the base 1131 to the end cap 1132, thus forming a substantially conical surface fit with the inverted cone or frustoconical first elastic module 1120, allowing the second elastic module 1130 to more securely hold the first elastic module 1120. See [reference needed]. Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 9 .

[0070] As can be seen, the conical fit between the receiving space 1135 of the first elastic module 1120 and the second elastic module 1130 is particularly convenient for assembly. A simple single insertion action—inserting the first elastic module 1120 from top to bottom into the receiving space 1135 of the second elastic module 1130—is sufficient to hold the first elastic module 1120 in place, thus assembling them into the desired elastic component 1110 without complex alignment and / or connection operations. This conical fit also facilitates the disassembly of the elastic component 1110, where a single pull-out action—pulling the first elastic module 1110 out of the receiving space 1135 of the second elastic module 1120—is sufficient to detach the first elastic module 1120 from the second elastic module 1120. In other embodiments, the first elastic module 1120 may have an outer surface of other shapes, and the receiving space 1135 of the second elastic module 1130 may also have a shape that matches the outer surface of the first elastic module 1120, thereby forming other non-conical surface fits, while having the aforementioned advantages of easy assembly and disassembly.

[0071] Furthermore, since the second elastic module 1130 has a hollow conical or truncated conical shape, and its base 1131 at its upper end has an opening 1137, this allows another second elastic module 1130 to be inserted into the receiving space 1135 within the current second elastic module 1130 via the opening 1137. This enables multiple second elastic modules 1130 to be stacked together in an unassembled state, such as... Figure 15 As shown, this facilitates the storage and transport of the second flexible module 1130 in a compact volume in its unassembled state.

[0072] It should also be noted that, see Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 9In the assembled state where the first elastic module 1120 is inserted into the second elastic module 1130, along the height direction Z, the upper end of the first elastic module 1120 extends beyond the receiving space 1135 of the second elastic module 1130, making the upper end of the first elastic module 1120 higher than the second elastic module 1130. Simultaneously, in the lateral direction perpendicular to the height direction Z, the second elastic module 1130 circumferentially surrounds and holds the first elastic module 1120. Thus, when the elastic pad 1000, particularly its main elastic layer 1100, experiences downward pressure, the first elastic module 1120 directly receives this pressure, while the second elastic module 1130 indirectly receives the downward pressure transmitted by the first elastic module 1120.

[0073] Figure 16 yes Figure 6 The side view of the main elastic layer 1100 shown below will be referenced below. Figure 16 To describe the elastic characteristics of the main elastic layer 1100. For example... Figure 16 As shown, the main elastic layer 1100 may include a plurality of elastic components 1110 arranged in an array in the XY plane. When one of the elastic components 1110a is subjected to a downward pressure F, or when the elastic component 1110a is located at the point of concentration of the pressure F, the elastic component 1110a may undergo a first compression process and selectively undergo a second compression process.

[0074] During the first compression process, the first elastic module 1120a in the elastic component 1110a first directly receives the downward pressure F and is significantly compressed downwards, while the second elastic module 1130a is not compressed downwards or is not significantly compressed downwards. Specifically, for the first elastic module 1120a having an inverted conical or truncated conical helical spring, see [reference needed]. Figure 13 The upper part of the first elastic module 1120a has a relatively small elastic coefficient (i.e., relatively soft) due to its larger diameter, while the lower part has a relatively large elastic coefficient (i.e., relatively hard) due to its smaller diameter. Thus, under pressure F, the upper part of the first elastic module 1120a will be significantly compressed first. During this first compression, although the second elastic module 1130a receives pressure from the first elastic module 1120a due to contact with it, the transmitted pressure is essentially distributed across the bottom and conical sides of the second elastic module 1130a. The upper end of the second elastic module 1130a does not receive a concentrated downward pressure, and therefore, the second elastic module 1130a is not significantly compressed.

[0075] Moreover, see Figure 4The second elastic modules 1130 of each elastic component 1110 are interconnected at the base 1131 to form an elastic base layer 1140. This means that the second elastic modules 1130 are not independent but have mutual influence. Thus, when a second elastic module 1130a receives downward pressure, this pressure is transmitted via the base 1131 to multiple second elastic modules 1130 in the surrounding area, and they collectively bear the pressure. This also prevents the second elastic module 1130a from undergoing significant deformation during the first compression process. Figure 16 The interconnected bases 1131 of each of the second elastic modules 1130 can actually form an interconnected elastic network extending in the XY plane (such as the portion enclosed by the dashed frame 1150). This interconnected elastic network 1150 is used to connect or link the second elastic modules 1130 of each elastic component 1110 in the main elastic layer 1100 to each other, so as to transmit pressure and / or elastic deformation between the interconnected second elastic modules 1130, thereby forming the aforementioned mutual entanglement. In this way, when the elastic component 1110a is compressed to a certain extent so that its second elastic module 1130a begins to undergo elastic deformation, pressure can be transmitted to the second elastic modules 1130 of other elastic components 1110 (especially adjacent elastic components) via the interconnected elastic network 1150, so that other elastic components 1110 (especially the second elastic modules 1130) can share the pressure together. In this embodiment, since the base 1131 is located at the upper end of the second elastic module 1130, or the helical spring 1133, it is positioned between the upper and lower ends of the assembled elastic component 1110. This also allows the interconnected elastic network 1150 to be located between the upper and lower surfaces of the entire main elastic layer 1100. In other embodiments, only a portion of the bases 1131 of the second elastic modules 1130 in the main elastic layer 1100 can be interconnected. The resulting interconnected elastic network 1150 can transmit pressure and / or elastic deformation only between the interconnected second elastic modules 1130, thereby contributing different elastic properties to the main elastic layer 2100.

[0076] Finally, alternatively or additionally, the second elastic module 1130a may be made to have a larger elastic coefficient, such as a stiffer helical spring 1133, so that the second elastic module 1130a will not deform significantly during the first compression.

[0077] It should be noted that during the first compression process, the elastic deformation of the main elastic layer 1100 is mainly provided by the elastic deformation of the first elastic module 1120 of the elastic component 1110. Moreover, the first elastic modules 1120 of each elastic component 1110 are independent of each other, thus exhibiting obvious elastic characteristics of independent spring pads.

[0078] If the deformation of the first elastic module 1120a during the first compression process is insufficient to completely resist the pressure F, a second compression process can be performed after the first compression process. During the second compression process, the entire elastic component 1110a continues to be compressed downwards by the pressure F. At this time, the first elastic module 1120a and the second elastic module 1130a are compressed downwards substantially synchronously. Moreover, as the second elastic module 1130a is compressed downwards, its base 1131 immediately transmits the deformation of the second elastic module 1130a directly to the second elastic modules 1130 of other adjacent elastic components 1110, thereby involving the adjacent second elastic modules 1130 in resisting the pressure F. From the perspective of the interconnected elastic network 1150 formed by the interconnected bases 1131, once the second elastic module 1130a is compressed, the compression deformation of the second elastic module 1130a is directly transmitted via the interconnected elastic network 1150 to the second elastic modules 1130 of other adjacent elastic components 1120, so that the second elastic modules 1130 of the other adjacent elastic components 1120 that receive the deformation can share the pressure with the current elastic component 1120a. Thus, the second compression process exhibits a higher elastic coefficient than the first compression process. In other words, one would perceive the second compression process of the main elastic layer 1100 as being "stiffer" than the first compression process.

[0079] Based on the combined first and second compression processes, the main elastic layer 1100 and the elastic pad 1000 having it have the following elastic characteristics: 1) They exhibit obvious two-stage elastic characteristics from "soft" to "hard"; and 2) They exhibit obvious independent elastic pad characteristics in the first stage, which is "soft", that is, the compression states of different regions of the elastic pad 1000 are independent and do not affect each other.

[0080] Second embodiment:

[0081] Figure 17 and Figure 18 An assembled elastic pad 2000 according to a second embodiment of the present invention is shown. Figure 17 and Figure 18As shown, the elastic pad 2000 is essentially a flat shape extending in the XY plane and has a height or thickness extending along the Z direction. The elastic pad 2000 may include a main elastic layer 2100 and a first pad layer 2200 covering the main elastic layer. The main elastic layer 2100 may be made of an elastic material and provides the primary source of elasticity for the elastic pad 2000. The first pad layer 2200 may be located above the main elastic layer 2100 and is closer to the human body than the main elastic layer 2100 during use. The first pad layer 2200 typically has a substantially continuous and flat surface to provide a more human-friendly surface for the elastic pad 2000. The first pad layer 2200 may also have a degree of elasticity to provide a secondary source of elasticity for the elastic pad 2000.

[0082] The main elastic layer 2100 may include a plurality of elastic components 2110 arranged in an array along the XY plane. The structure of the elastic pad 2000 and the elastic components 2110 is as follows: Figure 19 The exploded view shows it more clearly. For example... Figure 19 As shown, each elastic component 2110 in the main elastic layer 2100 may include a first elastic module 2120 and a second elastic module 2130 extending along the height direction Z and capable of elastic deformation along the height direction Z. The first elastic module 2120 can be inserted downward along the height direction Z into the corresponding second elastic module 2130 and held therein. That is, the second elastic module 2130 can be both an elastic module and a holding module for holding the first elastic module 2120. In the assembled state where the first elastic module 2120 is inserted into the second elastic module 2130, along the height direction Z, the upper end of the first elastic module 2120 extends into the receiving space 2135 of the second elastic module 2130 (see Figure 20 In addition to the above, the upper end of the first elastic module 2120 is higher than the second elastic module 2130. Simultaneously, in the lateral direction perpendicular to the height direction Z, the second elastic module 2130 circumferentially surrounds and holds the first elastic module 2120. Thus, when the elastic pad 2000, particularly its main elastic layer 2100, experiences downward pressure, the first elastic module 2120 directly receives the pressure, while the second elastic module 2130 indirectly receives the downward pressure transmitted by the first elastic module 2120.

[0083] It should be noted that in this assembled state, the first elastic modules 2120 of each elastic component 2110 can be independent of each other, while the second elastic modules 2130 of adjacent elastic components 2110 can be connected to each other.

[0084] The first elastic module 2120 of each elastic component 2110 in the elastic pad 2000 can adopt a similar shape and structure to the first elastic module 1120 in the elastic pad 1000 of the first embodiment, such as... Figure 13 As shown. The assembly process of elastic pad 2000 is also similar to that of elastic pad 1000 in the first embodiment. The main difference between elastic pad 2000 and elastic pad 1000 is the structure of the second elastic module 2130. Apart from that, the description of elastic pad 1000 above is also basically applicable to elastic pad 2000.

[0085] Figure 20 A second elastic module 2130, which can be applied to the elastic component 2110, is schematically shown. For example... Figure 20 As shown, the second elastic module 2130 may include a helical spring 2133 capable of elastic deformation. The helical spring 2133 can serve as the elastic body of the second elastic module 2130 and is hollow. The helical spring 2133 can be mounted and constrained between an annular seat 2139 and an end cap 2132. Specifically, the helical spring 2133 may have a hollow end (at...) Figure 20 The upper end of the middle section abuts against and is held by the seat ring 2139, while the other end (at the upper end) Figure 20 The lower end of the coil spring 2133 can abut against the end cap 2132. On the outside of the coil spring 2133, multiple flexible straps 2134 extend between the seat ring 2139 and the end cap 2132. Thus, by pre-determining the length of the flexible straps 2134, the distance between the seat ring 2139 and the end cap 2132 can be limited, allowing the coil spring 2134 to be constrained between the seat ring 2139 and the end cap 2132 in a pre-compressed state (not a completely free state). With the aid of the pre-compressed coil spring 2134, the resulting second elastic module 2130 can undergo elastic deformation while also possessing a certain stiffness. This stiffness of the second elastic module 2130 can help maintain its shape in a static state and provide suitable initial stiffness or initial support force when it is compressed and deformed. In other embodiments, the coil spring 2133 of the second elastic module 2130 can also adopt a similar design. Figure 13 The first elastic module 1120 shown is encapsulated and pre-compressed using a pocket spring, and then its upper end is mounted to the seat ring 2139. In appropriate cases, the second elastic module 1130 can also use a non-coil spring elastic body, such as a sponge or leaf spring.

[0086] return Figure 20A flat base 2131 can surround the helical spring 2134 and be positioned below the upper end of the helical spring 2133, or below the seat ring 2139, thus located between the seat ring 2139 and the end cap 2132 in the vertical direction (height direction Z). In other words, the base 2131 can be below the upper end of the second elastic module 2130 and located between the upper and lower ends of the second elastic module 2130. Typically, in the height direction Z, the base 2131 can be located between half the height of the helical spring 2133 and its upper end. The base 2131 can be connected to the seat ring 2139 located at the upper end of the helical spring 2134 via a flexible member 2138. This allows relative movement in the height direction Z between the upper end of the helical spring 2134, or the seat ring 2139, and the base 2131. The flexible element 2138 can be elastic, allowing force to be transmitted between the seat ring 2139 and the base 2131 in an elastic deformation manner, and can self-restore to its initial relative position after relative movement between the seat ring 2139 and the base 2131. The end cap 2132, the flexible strap 2134, and the flexible element 2138 can be made of the same material and can be integrally molded. In other embodiments, when the seat ring 2139 is omitted, the flexible element 2138 can also be directly attached to the upper ends of the base 2131 and the helical spring 2133, respectively.

[0087] The base 2131 of the second elastic module 2130 may have a connecting portion 2136 for interconnecting with the base 2131 of other adjacent elastic components 2110 during assembly, to form, for example... Figure 22 The elastic base layer 2140 shown is described in the first embodiment. A description of this elastic base layer 2140 can be found in the reference section of the first embodiment. Figure 4 The description of the elastic base layer 1140 will not be repeated here. Similar to the first embodiment, for ease of assembly, the bases 2131 of several second elastic modules 2130 can be integrally formed to create a module containing multiple second elastic modules. Figure 20 As shown, these connecting portions 2136 may include connecting portions 2136a and 2136b with concave and convex structures. The protrusion 2136a can be inserted into the recess 2136b of the base 2131 of an adjacent second elastic module 2130, and the recess 2136b can receive the protrusion 2136a of the base 2131 of the other second elastic module 2130. These connecting portions 2136 may also include connecting portions 2136c and 2136d of the "slide rail-groove" type. The slide rail 2136c can be inserted into the groove 2136d of the base 2131 of an adjacent second elastic module 2130, and the groove 2136d can receive the slide rail 2136c of the base 2131 of the other second elastic module 2130.

[0088] like Figure 20 As shown, the second elastic module 2130 and its helical spring 2133 can be tapered or truncated cone-shaped, tapering from the seat ring 2139 to the end cap 2132, and in the assembled state, the tapered or truncated cone shape can be inverted. The second elastic module 2130 can be hollow, and its seat ring 2139 can have an opening 2137, thereby allowing the second elastic module 2130 to have an upwardly opening receiving space 2135. The receiving space 2135 can be defined by the inner side of the helical spring 2133 and the upper surface of the end cap 2132. In this way, the first elastic module 2120 can be inserted from above into the receiving space 2135 of the second elastic module 2130, thereby allowing the second elastic module 2130 to hold the first elastic module 2120, forming the assembled elastic assembly 2110. The receiving space 2135 can also be an inverted cone or frustoconical shape that tapers gradually from the seat ring 2139 to the end cap 2132. Therefore, it can substantially form a conical surface fit with the inverted cone or frustoconical first elastic module 2120, thereby allowing the second elastic module 2130 to more securely hold the first elastic module 2120. It can be seen that this conical surface fit between the receiving space 2135 of the first elastic module 2120 and the second elastic module 2130 is particularly convenient for assembling and disassembling the elastic component 2110, as can be seen in the preceding description of the elastic component 1110 in the first embodiment, which will not be repeated here. In other embodiments, other shaped surface fits between the receiving space 2135 of the first elastic module 2120 and the second elastic module 2130 that facilitate assembly and disassembly are also feasible. Moreover, the cone or frustoconical shape of the second elastic module 2130 and its upwardly opening receiving space 2135 also allow multiple second elastic modules 2130 to be stacked together, such as... Figure 21 As shown, this facilitates the storage and transport of the second elastic module 2130 in a compact volume when unassembled. It should be noted that, for ease of stacking, the flexible element 2138 may extend outward and downward from the upper end of the helical spring 2133.

[0089] Figure 23 yes Figure 17 and Figure 18 A side view of the main elastic layer 2100, which will be referred to below. Figure 23 To describe the elastic characteristics of the main elastic layer 2100. For example... Figure 23As shown, the main elastic layer 2100 may include a plurality of elastic components 2110 arranged in an array in the XY plane. When one of the elastic components 2110a is subjected to a downward pressure F, or when the elastic component 2110a is located at the point of concentration of the pressure F, the elastic component 2110a can undergo a first compression process and selectively undergo a second and third compression process.

[0090] During the first compression process, the first elastic module 2120a in the elastic component 2110a first directly receives the downward pressure F and is significantly compressed downwards, while the second elastic module 2130a is not compressed downwards or is not significantly compressed downwards. Specifically, for the first elastic module 2120a with an inverted conical or frustoconical helical spring, its upper part has a relatively small elastic coefficient (i.e., relatively soft) due to its larger diameter, while its lower part has a relatively large elastic coefficient (i.e., relatively stiff) due to its smaller diameter. Thus, under the action of pressure F, the upper part of the first elastic module 2120a will be significantly compressed first. During the first compression process, although the second elastic module 2130a receives pressure from the first elastic module 2120a due to contact with it, the pressure is basically distributed on the bottom surface and conical side surface of the second elastic module 2130a. The upper end of the second elastic module 2130a does not receive a significant concentrated downward pressure, so the second elastic module 2130a is not significantly compressed.

[0091] Moreover, see Figure 22 The second elastic modules 2130 of each elastic component 2110 form an elastic base layer 2140 through their interconnection at the base 2131. This means that the second elastic modules 2130 are not independent but have mutual influence. Thus, when the flexible member 2138 is a force-transmitting elastic member, when the second elastic module 2130a receives downward pressure, this pressure is transmitted via the flexible member 2138 and the base 2131 to multiple second elastic modules 2130 in the surrounding area, and together they bear the pressure. This also ensures that the second elastic module 2130a does not undergo significant deformation during the first compression process.

[0092] Finally, alternatively or additionally, the second elastic module 2130a may be made to have a larger elastic coefficient, such as a stiffer coil spring 2133, so that the second elastic module 2130a does not deform significantly during the first compression.

[0093] It should be noted that during the first compression process, the elastic deformation of the main elastic layer 2100 is mainly provided by the elastic deformation of the first elastic module 2120 of the elastic component 2110. Moreover, the first elastic modules 2120 of each elastic component 2110 are independent of each other, thus exhibiting obvious elastic characteristics of independent spring pads.

[0094] If the deformation of the first elastic module 2120a during the first compression process is insufficient to completely resist the pressure F, a second compression process can be performed after the first compression process. During the second compression process, the entire elastic component 2110a continues to be compressed downward by the pressure F. At this time, the first elastic module 2120a and the second elastic module 2130a are compressed downward in a substantially synchronous manner.

[0095] The upper end of the second elastic module 2130a, or its seat ring 2139, is connected to the base 2131 via a flexible member 2138. When the flexible member 2138 is elastic, at the beginning of the second compression process, as the second elastic module 2130a is compressed downwards, the downward displacement of the seat ring 2139 caused by the deformation of the second elastic module 2130a can be significantly absorbed by the flexible member 2138 and will not be significantly transmitted to the second elastic modules 2130 of other adjacent elastic components 2110. That is, in the second compression process, the pressure F is mainly resisted by the deformation of the first elastic module 2120a and the second elastic module 2130a, and the interconnecting elastic network 2150 and other adjacent elastic components 2110 do not participate significantly. The main elastic layer 2110 of the second embodiment exhibits a higher elastic coefficient in the second compression process than in the first compression process. In other words, people will feel that the second compression process of the main elastic layer 2100 is "harder" than the first compression process.

[0096] If the deformation of the first elastic module 2120a and the second elastic module 2130a during the second compression process is insufficient to completely resist the pressure F, then a third compression process can be performed after the second compression process.

[0097] During the third compression process, because the flexible element 2138 can no longer absorb the deformation of the second elastic module 2130a, or because the seat ring 2139 of the second elastic module 2130a has moved downward to a position substantially flush with the base 2131, the base 2131 will begin to bear the pressure F significantly, and will directly transfer the deformation of the second elastic module 2130a to the second elastic modules 2130 of other adjacent elastic components 2110, thereby causing the adjacent second elastic modules 2130 to be involved in resisting the pressure F. From the perspective of the interconnected elastic network 2150 formed by the interconnected bases 2131, when the base 2131 begins to bear the pressure F significantly, that is, when the interconnected elastic network 2150 begins to bear the pressure F significantly. At this point, the interconnected elastic network 2150 will significantly participate in the compression process and transmit the pressure F to the second elastic modules 2130 of the adjacent elastic components 2120, so that the second elastic modules 2130 of the adjacent elastic components 2120 will bear the pressure together with the current elastic component 2120a. Thus, the third compression process will exhibit a higher elasticity coefficient than the second compression process. In other words, one will perceive the third compression process of the main elastic layer 2100 as being "stiff" than the second compression process.

[0098] See Figure 23 It should be noted that the interconnected bases 2131 of each second elastic module 2130 can actually form an interconnected elastic network extending in the XY plane (such as the portion enclosed by the dashed frame 2150). This interconnected elastic network 2150 is used to connect or link the second elastic modules 2130 of each elastic component 2110 in the main elastic layer 2100 to each other, so as to transmit pressure and / or elastic deformation between the interconnected second elastic modules 2130, thereby forming the aforementioned mutual entanglement. In this way, when the elastic component 2110a is compressed to a certain extent so that its second elastic module 2130a begins to undergo elastic deformation, pressure can be transmitted to other adjacent elastic components 2110 (especially adjacent elastic components) via the interconnected elastic network 2150, so that other elastic components 2110 (especially second elastic modules 2130) can share the pressure together. In this embodiment, since the base 2131 is located at the upper end of the second elastic module 2130, or the helical spring 2133, it is positioned between the upper and lower ends of the assembled elastic component 2110. This also allows the interconnected elastic network 2150 to be located between the upper and lower surfaces of the entire main elastic layer 2100. In other embodiments, only a portion of the bases 2131 of the second elastic modules 2130 in the main elastic layer 2100 can be interconnected. The resulting interconnected elastic network 2150 can transmit pressure and / or elastic deformation only between the interconnected second elastic modules 2130, thereby contributing different elastic properties to the main elastic layer 2100.

[0099] Based on the first to third compression processes, the main elastic layer 2100 and the elastic pad 2000 having it have the following elastic characteristics: 1) They exhibit obvious three-stage elastic characteristics from "soft" to "hard" to "harder", which is different from the two-stage elastic characteristics of the elastic pad 1000; and 2) They exhibit obvious independent elastic pad characteristics in both the first and second stages, that is, the compression states of different regions of the elastic pad 2000 are independent and do not affect each other.

[0100] In the preceding description, the base 2131 is lower than the upper end of the second elastic module 2130 and is located between the upper and lower ends of the second elastic module 2130. In another embodiment not shown, the base 2131 may be positioned higher than the upper end of the coil spring 2133, or higher than the seat ring 2139. That is, the base 2131 forms the upper end of the entire second elastic module 2130 and is located between the upper and lower ends of the entire elastic component 2100. Thus, after only the first elastic module 2120 is compressed, and before the first and second elastic modules 2120 and 2130 are compressed simultaneously, the interconnected elastic network 2150 formed by the interconnected bases 2131 will participate, involving other adjacent elastic components 2110 to resist the pressure F together. That is, the interconnected elastic network 2150 will be more effective than the first elastic module 2120. Figure 23 The situation shown engages earlier, thus the elastic pad and main elastic layer exhibit different elastic characteristics than in the second embodiment.

[0101] In yet another embodiment (not shown), the position of the base 2131 within the second elastic module 2130 can be further lowered, such that the base 2131 is located at the lower end of the second elastic module 2130, and thus also at the lower end of the entire elastic component 2110. In this way, the interconnected structure formed by the interconnected bases 2131 will not participate in any compression process, thereby causing the elastic pad and main elastic layer to exhibit elastic characteristics different from those in the second embodiment.

[0102] Third embodiment:

[0103] Figure 24 and Figure 25 An assembled elastic pad 3000 according to a third embodiment of the present invention is shown. Figure 24 and Figure 25As shown, the elastic pad 3000 is essentially a flat shape extending in the XY plane and has a height or thickness extending along the Z direction. The elastic pad 3000 may include a main elastic layer 3100 and a first pad layer 3200 covering the main elastic layer. The main elastic layer 3100 may be made of an elastic material and provides the primary source of elasticity for the elastic pad 3000. The first pad layer 3200 may be located above the main elastic layer 3100 and is closer to the human body during use than the main elastic layer 3100. The first pad layer 3200 typically has a substantially continuous and flat surface to provide a more human-friendly surface for the elastic pad 3000. The first pad layer 3200 may also have a degree of elasticity to provide a secondary source of elasticity for the elastic pad 3000.

[0104] It should be noted that although the first pad 3200 is generally flat, this does not preclude the possibility that the upper surface of the first pad 3200 may have concave and / or convex structures 3220 that do not affect the comfort of human contact, and such structures are preferably elastic.

[0105] The main elastic layer 3100 may include a plurality of elastic components 3110 arranged in an array along the XY plane. The structure of the elastic pad 3000 and the elastic components 3110 is as follows: Figure 26 The exploded view shows it more clearly. For example... Figure 26 As shown, each elastic component 3110 in the main elastic layer 3100 may include a first elastic module 3120 and a second elastic module 3130 extending along the height direction Z and capable of elastic deformation along the height direction Z. The first elastic module 3120 can be inserted downward along the height direction Z into the corresponding second elastic module 3130 and held therein. That is, the second elastic module 3130 can be both an elastic module and a holding module for holding the first elastic module 3120. In the assembled state where the first elastic module 3120 is inserted into the second elastic module 3130, along the height direction Z, the upper end of the first elastic module 3120 extends into the receiving space 3135 of the second elastic module 3130 (see...). Figure 27 In addition to the above, the upper end of the first elastic module 3120 is higher than the second elastic module 3130. Simultaneously, in the lateral direction perpendicular to the height direction Z, the second elastic module 3130 can circumferentially surround and hold the first elastic module 3120. Thus, when the elastic pad 3000, particularly its main elastic layer 3100, experiences downward pressure, the first elastic module 3120 directly receives the pressure, while the second elastic module 3130 indirectly receives the downward pressure transmitted by the first elastic module 3120.

[0106] It should be noted that in this assembled state, the first elastic modules 3120 of each elastic component 3110 can be independent of each other, while the second elastic modules 3130 of adjacent elastic components 3110 can be connected to each other.

[0107] The first elastic module 3120 of each elastic component 3110 in the elastic pad 3000 can adopt a shape and structure similar to the first elastic module 1120 in the elastic pad 1000 of the first embodiment or the first elastic module 2120 in the elastic pad 2000 of the second embodiment, such as... Figure 13 As shown. The assembly process of elastic pad 3000 is also similar to that of elastic pads 1000 and 2000 in the first and second embodiments. The main difference between elastic pad 3000 and elastic pads 1000 and 2000 is the structure of the second elastic module 3130. Apart from that, the description of elastic pads 1000 and 2000 above also applies to elastic pad 3000.

[0108] Figure 27 and Figure 28 A second elastic module 3130, which can be applied to the elastic component 3110, is schematically shown. For example... Figure 27 and Figure 28 As shown, the second elastic module 3130 may include a helical spring 3133 capable of elastic deformation. The helical spring 3133 serves as the elastic body of the second elastic module 3130 and is hollow. Along the height direction Z, the helical spring 3133 can be mounted and constrained between a mounting cylinder 3132 and a flat base 3131. The base 3131 may be located at the lower end of the elastic component 3110. The mounting cylinder 3132 may be made of a non-deformable, inelastic material and may have a laterally outwardly extending flange 3139 at its upper end. Thus, the helical spring 3133 can abut against the lower surface of the flange 3139 of the mounting cylinder 3132 at its upper end to support the mounting cylinder, and abut against the base 3132 at its lower end. The mounting cylinder 3132 extends downward from its flange 3139 inside the helical spring 3133, thus extending substantially inside the helical spring 3133. The downward or upward movement of the mounting cylinder 3132 can correspondingly compress or release the coil spring 3133. In other embodiments, the mounting cylinder 3132 may also be connected to the upper end of the coil spring 3133 in other suitable ways.

[0109] To securely hold the helical spring 3133, the base 3131 may have an annular groove 3131a, allowing the lower end of the helical spring 3133 to be detachably fitted into the annular groove 3131a. On the outside of the helical spring 3133, a plurality of flexible straps 3134 extend between the mounting cylinder 3132 and the base 3131. Thus, by pre-determining the length of the flexible straps 3134, the distance between the mounting cylinder 3132 and the base 3131 can be limited, allowing the helical spring 3134 to be constrained between the mounting cylinder 3132 and the base 3131 in a pre-compressed state (not a completely free state). With the aid of the pre-compressed helical spring 3134, the resulting second elastic module 3130 can undergo elastic deformation while also possessing a certain stiffness. This stiffness of the second elastic module 3130 helps maintain its shape in a static state and provides suitable initial stiffness or initial support force when it is compressed and deformed. The flexible strap 3134 and the mounting cylinder 3132 can be made of the same material and are integrally formed.

[0110] The base 3131 of the second elastic module 3130 may have a connecting portion 3136 for interconnecting with the base 3131 of the second elastic module 3130 of other adjacent elastic components 3110 during assembly, to form, for example... Figure 30 The elastic base layer 3140 shown is described in the first embodiment. A description of this elastic base layer 3140 can be found in the reference section of the first embodiment. Figure 4 The description of the elastic base layer 1140 will not be repeated here. Similar to the first embodiment, for ease of assembly, the bases 2131 of several second elastic modules 2130 can be integrally formed to create a module containing multiple second elastic modules. Figure 27 As shown, these connecting parts 3136 may include "slide rail-groove" type connecting parts 3136c and 3136d. The slide rail 3136c can be inserted into the groove 3136d of the base 2131 of another adjacent second elastic module 3130, and the groove 3136d can receive the slide rail 3136c of the base 3131 of the other second elastic module 3130.

[0111] like Figure 27As shown, the helical spring 3133 of the second elastic module 3130 can be a tapered or frustoconical shape that tapers from the upper end to the lower end along the vertical direction or the height direction Z. Furthermore, in the assembled state, this tapered or frustoconical shape can be upright, unlike the inverted tapered or frustoconical helical springs 1133 and 2133 in the first and second embodiments. In this case, the mounting cylinder 3132 can provide the necessary receiving space 3135 to receive the inverted tapered or frustoconical first elastic module 3120. The mounting cylinder 3132 can be hollow, and its upper end can have an opening 3137U, so that the mounting space 3135 of the mounting cylinder 3132 is open upwards. This allows the first elastic module 3120 to be inserted from above into the receiving space 3135 of the second elastic module 3130, thereby holding the first elastic module 3120 in place by the second elastic module 3130, forming the assembled elastic assembly 3110. The receiving space 3135, defined by the inner surface of the hollow mounting cylinder 3132, can also be an inverted cone or frustoconical shape that tapers from the upper end to the lower end in the assembled state. Therefore, it can substantially form a conical surface fit with the inverted cone or frustoconical first elastic module 3120 in the assembled state, thereby allowing the second elastic module 3130 to more securely hold the first elastic module 3120. The mounting cylinder 3132 can securely hold the first elastic module 3120 solely by this surface fit with the first elastic module 3130, without requiring any other connection or fixing operations.

[0112] As can be seen, the conical surface fit between the receiving space 3135 of the first elastic module 3120 and the second elastic module 3130 is particularly convenient for assembling and disassembling the elastic component 2110. This can be referred to the relevant description of the elastic component 1110 in the first embodiment above, and will not be repeated here. In other embodiments, other shaped surface fits between the receiving spaces 3135 of the first elastic module 3120 and the second elastic module 3130 that facilitate assembly and disassembly are also feasible.

[0113] The second elastic module 3130 generally has an M-shaped cross-section. The outer contour formed by the helical spring 3122 of the second elastic module 3130 is basically an upright cone or frustocone, while the inner contour formed by the mounting cylinder 3132 is an inverted cone or frustocone. Figure 27The cross-sectional view shown makes this clearer. Furthermore, the base 3131 of the second elastic module 3130 may have an opening 3131b, and the size of this opening 3131b may be larger than the size of the upper end of the second elastic module 3130, for example, larger than the diameter of the annular flange 3139. Because the second elastic module 3130 has a hollow M-shaped form, and its base 3131 at its lower end has an opening 3131b, this allows another second elastic module 3130 to be inserted into the current second elastic module 3130 through this opening 3131b, thereby enabling multiple second elastic modules 3130 to be stacked together in an unassembled state, such as... Figure 29 As shown, this facilitates the storage and transport of the second flexible module 3130 in a compact volume in its unassembled state.

[0114] See Figure 28 In this diagram, the dashed line D represents the plane containing the bottom surface of the second elastic module 3130, which is located at the lowest point of the second elastic module 3130. It can be understood that the plane shown by the dashed line D is also the plane on which the bottom surfaces of the elastic component 3110 and the main elastic layer 3100 rest, as shown below. Figure 25 and 37 As shown. Return Figure 28 As can be seen, the lower end of the mounting cylinder 3132 can be significantly higher than the bottom surface of the second elastic module 3130. Thus, when the mounting cylinder 3132 is subjected to downward pressure, it can move downward by compressing the coil spring 3133. The mounting cylinder 3132 may also have an opening 3137L at its lower end. Thus, as... Figure 31 As shown, when the first elastic module 3120 is inserted into the second elastic module 3130 to form the elastic component 3110, the lower end of the first elastic module 3120 first passes through the upper opening 3137U of the mounting cylinder 3132, and then through the lower opening 3137L of the mounting cylinder 3132, until the first elastic module 3120 is securely held by the mounting cylinder 3132. By pre-determining the taper of the first elastic module 3120 and the mounting cylinder 3132, as well as the length of the first elastic module 3120, it is possible to ensure that, in the assembled state, the lower end of the first elastic module 3120 is above the bottom surface of the second elastic module 3130 or the elastic component 3110 shown by the dashed line D, or in other words, suspended above the bottom surface.

[0115] Thus, see Figure 31When the elastic component 3110 is subjected to a downward pressure F, the first elastic module 3120 directly receives the pressure F and is significantly compressed downwards. During the compression of the first elastic module 3120, due to its contact with the mounting cylinder 3132 of the second elastic module 3130, the pressure is rapidly transmitted to the conical side of the mounting cylinder 3132. Since the lower ends of the mounting cylinder 3132 and the first elastic module 3120 are suspended, the pressure on the conical side of the mounting cylinder 3132 is concentrated at its flange 3139 and acts on the upper end of the coil spring 3133, thereby causing the second elastic module 3130 to also be subjected to a significant downward pressure, which, together with the first elastic module 3120, counteracts the pressure F. In other words, for the elastic component 3110 of this embodiment, the first elastic module 3120 and the second elastic module 3130 essentially work together from the beginning to counteract the pressure F. This differs from the elastic components 1110 and 2110 in the first and second embodiments, in which the first elastic modules 1120 and 2120 primarily resist the pressure F during the first compression process, while the second elastic modules 1130 and 2130 do not significantly participate.

[0116] Since the helical spring 3133 of the second elastic module 3130 is an upright cone or frustoconical shape, while the helical spring of the first elastic module 3130 (not shown in the figure) is an inverted cone or frustoconical shape, and they work together when the elastic component 3110 is subjected to a downward pressure F, the overall elastic performance of the elastic component 3110 is similar to... Figure 32 The concave helical spring shown. Compared to the first and second embodiments, during the first compression process, it is mainly composed of, for example... Figure 13 When the inverted conical helical spring 1124 shown is in operation, the elastic component 3110 of this embodiment will initially exhibit a "softer" elastic characteristic.

[0117] Furthermore, in this third embodiment, the base 3131 of the second elastic module 3130 is located on the bottom surface (dashed line D) of the entire elastic component 3110. Therefore, the connection point of adjacent second elastic modules 3130 is also located on the bottom surface of the elastic component 3110. In this way, other elastic components 3110 will not be involved during the entire compression process of the elastic component 3110, thus exhibiting better independent spring pad elastic characteristics compared to the elastic components 1110 and 2110 in the first and second embodiments.

[0118] Compared to a single concave helical spring, the elastic component 3110 can be composed of two independent conical helical springs, namely the first and second elastic modules 3120 and 3130. This allows for the creation of a wider variety of elastic properties by adjusting the elastic characteristics of each spring individually. Furthermore, the conical shape of each of the first and second elastic modules 3120 and 3130 facilitates their stacking and storage. Finally, assembling the first and second elastic modules 3120 and 3130 is simple; the first elastic module 3120 is simply inserted into the second elastic module 3130 from above.

[0119] Other embodiments:

[0120] Figure 33 A resilient component 4110 of another embodiment is schematically shown. (As...) Figure 33 As shown, similar to the elastic components 1110, 2110, and 3110 in the first to third embodiments, the elastic component 4110 may include a first elastic module 4120 and a second elastic module 4130 capable of elastic deformation along the height direction Z of the elastic pad. Along the height direction Z, the upper end of the first elastic module may be higher than the second elastic module. Simultaneously, in the lateral direction perpendicular to the height direction Z, the second elastic module 4130 may circumferentially surround the first elastic module 4120. That is, the taller first elastic module 4120 is the inner elastic module, and the shorter second elastic module 4130 is the outer elastic module.

[0121] Unlike the elastic components 1110, 2110, and 3110 in the first to third embodiments, the first elastic module 4110 and the second elastic module 4130 of elastic component 4110 may not have a mating relationship where one holds the other. Thus, when elastic component 4110 is subjected to downward pressure, the first elastic module 4120 directly receives the pressure first, but the first elastic module 4120 does not significantly transmit the pressure to the second elastic module 4130. Therefore, during the first compression process, the first elastic module 4120 is significantly compressed downwards, while the second elastic module 4130 is not compressed downwards. In other words, during the first compression process, the deformation of elastic component 4110 along the height direction Z is entirely provided by the deformation of the first elastic module. The second compression process begins after the first elastic module 4120 has been significantly compressed a certain distance, for example, when its upper end is substantially flush with the upper end of the second elastic module 4130. During the second compression process, the second elastic module 4130 can directly receive the pressure together with the first elastic module 4120 and be compressed downwards synchronously. In other words, during the second compression process, the deformation of the elastic component 4110 along the height direction Z is provided by the deformation of the first and second elastic modules 4120 and 4130.

[0122] It is important to note that, compared to the first elastic module 4120 alone resisting pressure during the first compression process, the first and second elastic modules 4120 and 4130 jointly resist pressure during the second compression process. Therefore, the elastic component 4110 as a whole exhibits a larger elastic coefficient during the second compression process than during the first compression process, and people will perceive the elastic component 4110 and the elastic pad it constitutes as being "harder" during the second compression process. Thus, the elastic component 4110 can also provide a two-stage elastic characteristic from "soft" to "hard".

[0123] Figure 34 Another embodiment of the elastic component 5110 is schematically illustrated. The difference from elastic component 4110 is that in elastic component 5110, the taller first elastic module 5120 is the outer elastic module, and the shorter second elastic module 5130 is the inner elastic module. The compression process and elastic characteristics of elastic component 5110 are similar to those of elastic component 4110.

[0124] Figure 33 and Figure 34 Each elastic module of the elastic components 4110 and 5110 shown can be a helical spring with a uniform diameter along the Z-direction of height, or a pocket spring made of flexible material wrapped around a helical spring. During assembly, the outer elastic modules 4130 and 5120 are simply fitted over the inner elastic modules 4120 and 5130. Although not shown, the elastic components 4110 and 5110 may also have a base to connect adjacent elastic components during the assembly of the main elastic layer. Arranging multiple elastic components 4110 and 5110 in an array along the XY plane can constitute the main elastic layer of the elastic pad. By laying a first pad layer, as in the first to third embodiments, on top of this main elastic layer, the desired elastic pad can be assembled.

[0125] In the elastic components of the first to third embodiments, the first elastic module is generally conical or frustoconical, and the second elastic module, used to hold the receiving space of the first elastic module, is also generally conical or frustoconical. In other embodiments, the receiving space and the first elastic module may not be generally tapered, but rather each have tapered portions. The corresponding tapered portion of the first elastic module is held by the tapered portion of the receiving space of the second elastic module, and is substantially formed as a conical fit. The tapered portions are only formed locally, which may be disadvantageous for the compact storage and transport of the first and second elastic modules in a stacked manner, but it is still feasible when manufacturing and selling integrated elastic pads.

[0126] In one embodiment, the elastic component may include a first elastic module extending along the height direction of the elastic pad and a retaining module for retaining the first elastic module. The retaining module may have an upwardly opening receiving space to allow the first elastic module to be inserted downwards into the receiving space and thereby retain it. With the first elastic module inserted into and held by the receiving space of the retaining module, the upper end of the first elastic module may extend upwards out of the receiving space and above the retaining module, so that when the elastic component is subjected to downward pressure, the first elastic module receives the pressure first. The first elastic module may be selected from one of the first elastic modules described in the foregoing embodiments. The retaining module may be elastic and may be selected from one of the second elastic modules described in the foregoing embodiments capable of elastic deformation along the height direction of the elastic pad, thus forming an elastic component as described in the first to third embodiments.

[0127] The retaining module can also be non-elastic. For example, the retaining module can have the retaining features of the second elastic module (such as a receiving space), while omitting the elastic features (such as a coil spring) of the second elastic module. In some embodiments, the retaining module can be in the form of a retaining seat formed of a non-deformable material, and has a receiving space for retaining the first elastic module as described above. Such a retaining module is a substantially rigid module that does not deform substantially along the height direction Z. It should be understood that the elastic component constructed with such a retaining module also has the advantages of easy assembly and disassembly of the elastic components described in the first and third embodiments, that is, the assembly and disassembly of the elastic component can be achieved with a simple single insertion or pull-out action.

[0128] by Figure 31 Taking the elastic component 3110 as an example, in order for the retaining module (here, the second elastic module 3130) to stably hold the first elastic module 3120, in the assembled state, the height H1 of the portion of the first elastic module 3120 located above the upper end of the retaining module 3130 preferably does not exceed 80% of the total height H2 of the first elastic module 3120. Typically, H1 can be between 30% and 70% of H2. This also applies to the elastic components in the first and second embodiments, as well as elastic components including other types of retaining modules.

[0129] In one embodiment, the elastic pad may include a main elastic layer, which may include a plurality of elastic components and an interconnected elastic network. Each elastic component may include first and second elastic modules. The elastic pad may be the elastic pad 1000 or 2000 of the first and second embodiments, wherein the interconnected elastic network may be formed by interconnected bases 1131 or 2131, such as... Figure 16 and27 The interconnecting resilient network 1150 and 2150 are shown. In other embodiments, the interconnecting resilient network can be other structures independent of the base. For example, it can be... Figure 20 The base 2131 and flexible element 2138 in the second elastic module 2130 shown are omitted, and the seat rings 2139 of adjacent second elastic modules are connected to each other with connectors during assembly, thereby forming an internet. For example, for... Figure 33 The elastic component 4110 shown can form a main elastic layer 4100 when multiple such elastic components 4110 are arranged in a dense array, such as... Figure 35 As shown. It's important to understand that, for clarity of illustration, Figure 35 Only a small number of elastic components 4110 are shown. On the bottom surface of the main elastic layer 4100, the second elastic modules 4130 of adjacent elastic components 4110 in directions parallel and perpendicular to the paper can be locally connected by means of bonding, welding, etc. The connection positions are schematically indicated by black dots in the figure. Such connection methods can also form the required interconnected elastic network 4150.

[0130] In one embodiment, an elastic pad may include a flat base layer and a plurality of first elastic modules located in its extending plane. The base layer may have an upper surface and a lower surface opposite to the upper surface. The base layer may have a plurality of retaining recesses arranged in an array on its upper surface, each retaining recess recessed downward from the upper surface of the base layer. Each first elastic module may extend along the height direction of the elastic pad and is capable of elastic deformation along the height direction. The lower end of each first elastic module may be inserted into a recess of the base layer for retention by the base layer. The upper end of each first elastic module may extend upward beyond the upper surface of the base layer. The base layer may be elastic along the height direction Z; such a base layer may be, for example, the elastic base layers 1140, 2140, and 3140 in the first to third embodiments. Such an elastic base layer is formed by multiple second elastic modules 1130, 2130, and 3130 extending in the height direction Z interconnected in the extending plane XY, and the receiving space therein forms the retaining recesses in this embodiment. See, for example, [reference needed]. Figure 4The accommodating space 1135 of the second elastic module 1130 also serves as the retaining recess 1143 of the elastic base layer 1140. The specific structure of the second elastic module can be found in the preceding description and will not be repeated here. It should be understood that the second elastic body of the second elastic modules 1130, 2130, and 3130 constituting the elastic base layers 1140, 2140, and 3140 can be helical springs 1133, 2133, and 3133 extending along the height direction, making the elastic base layers 1140, 2140, and 3140 essentially a spring mesh with a certain thickness. In other embodiments, the base layer can adopt other suitable forms of spring mesh.

[0131] In another embodiment, the base layer may also be integrally molded from other elastic materials, such as sponge, silicone, rubber, etc. Figures 36-39 As shown. Figure 36 The image shows a base layer 6140, which has a flat body 6144 made of an elastic material such as sponge, an upper surface 6141, and a lower surface 6142 opposite to the upper surface 6141. The base layer 6140 may also have a plurality of retaining recesses 6143 arranged in an array on its upper surface 6141, each retaining recess 6143 recessed from the upper surface 6141 into the body 6144, i.e., recessed downwards towards the lower surface 6142. The retaining recesses 6143 may have an inverted conical or truncated conical shape, i.e., their lateral dimensions taper along the direction from the upper surface 6141 to the lower surface 6142. Figure 37 The cross-sectional view makes it clearer. Maintaining this conical or truncated conical shape of the recess 6143 is particularly suitable for maintaining the inverted conical or truncated conical shape of the first elastic module 6120, such as... Figure 38 As shown. Each first elastic module 6120 can extend along the height direction Z of the elastic pad and is capable of elastic deformation along the height direction Z. Each first elastic module 6120 corresponds to a retaining recess 6143, and the lower end of the first elastic module 6120 can be inserted into the corresponding retaining recess 6143 in the base layer 6140 so as to be retained by the base layer 6140. Figure 39As shown, with the first elastic module 6120 inserted into the retaining recess 6143, the upper end of the first elastic module 6120 can extend upwards beyond the retaining recess 6143, that is, extend beyond the upper surface 6143 of the base layer 6140. A first pad layer 6200 is laid on the array of first elastic modules 6120 to form an elastic pad 6000. The first elastic module 6120 can be similar to the first elastic modules in the foregoing embodiments, such as first elastic modules 1120, 2120, and 3120, which will not be described in detail here. In other embodiments, the base layer 6140 can also be inelastic, thus not contributing elasticity to the elastic pad 6000, but only serving to retain the first elastic module 6120. In this case, the main body 6144 of the base layer 6140 can be made of a suitable inelastic material.

[0132] like Figure 40 As shown, the elastic pads of the aforementioned embodiments, after being wrapped with an outer cover, are placed on a supporting bed frame to form a bed. In other embodiments, the elastic pads of the aforementioned embodiments can also be placed directly on the ground for use as a bed, depending on the circumstances. In other embodiments, the elastic pads of the aforementioned embodiments can be arranged on a sofa frame to form the desired sofa.

[0133] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
