Description

Technical Field

[0001] The present disclosure relates to the field of furniture, and in particular to a resilient pad used for furniture such as a bed or a sofa. Background Art

[0002] To improve sitting or lying comfort, furniture such as beds and sofas often have elastic pads. Various elastic pads are available in the prior art, such as sponge pads and spring pads. Traditional elastic pads are typically integrated, making them inconvenient to carry. Therefore, a user-friendly elastic pad is desired.

[0003] Various solutions have been proposed in the prior art to improve the comfort of spring mattresses, such as those made of independent pocket springs and independent spring modules. However, the elasticity characteristics that these mattresses can provide are still limited. People desire a wider range of options for elastic mattresses with different elasticity characteristics. Summary of the Invention

[0004] The present disclosure at least partially solves or alleviates the above-mentioned deficiencies in the prior art.

[0005] According to one aspect of the present 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 undergoing elastic deformation along the height direction. In the lateral 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, and the outer elastic module surrounds the inner elastic module along its circumference on the outside of the inner elastic module. Along the height direction, the upper end of the first elastic module is higher than the second elastic module, so 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. The present disclosure also provides an elastic pad including the elastic component, and furniture including the elastic pad.

[0006] According to another aspect of the present disclosure, an elastic component for an elastic pad is provided. The elastic component includes a first elastic module extending in the height direction of the elastic pad and a retaining module for retaining the first elastic module. The retaining module is formed with an upwardly open accommodating space to allow the first elastic module to be inserted from above downward into the accommodating space of the retaining module, thereby retaining the first elastic module. In a state where the first elastic module has been inserted into and retained by the accommodating space of the retaining module, the upper end portion of the first elastic module extends upward out of the accommodating space and is higher than the retaining module, so that when the elastic component is subjected to downward pressure, the pressure is first received by the first elastic module. The present disclosure also provides an elastic pad including the elastic component, and furniture including the elastic pad.

[0007] According to another aspect of the present disclosure, an elastic pad is provided. The elastic pad includes a primary elastic layer that provides the primary source of elasticity. The primary elastic layer includes a plurality of elastic components arranged in an array within a plane extending perpendicular to the height direction of the elastic pad. Each elastic component includes a first elastic module extending along the height direction of the elastic pad and capable of elastic deformation along the height direction, and a second elastic module, the second elastic module surrounding the first elastic module along its circumference. Along the height direction, the upper end of the first elastic module is higher than the second elastic module, so that when the elastic pad 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 primary elastic layer also includes an interconnected elastic network. The interconnected elastic network extends within a plane perpendicular to the height direction and is located between the upper and lower surfaces of the primary elastic layer. The interconnected elastic network is connected to the second elastic modules of at least some of the plurality of elastic components, and is used to transmit 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 at least a portion of the elastic assembly undergoes elastic deformation due to the pressure, the pressure is transmitted to the other connected second elastic modules via the interconnected elastic network, so that the interconnected second elastic modules jointly bear the pressure. The present disclosure also provides furniture including the elastic pad.

[0008] According to another aspect of the present disclosure, a retaining module for an elastic pad is provided, which is used to retain a first elastic module and form an elastic component extending along the height direction of the elastic pad together with the first elastic module. 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 is open upward to allow the first elastic module to be inserted from above into the receiving space of the mounting cylinder, thereby retaining the first elastic module. The downward or upward movement of the mounting cylinder can compress or release the second elastic body accordingly. The present 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 the present disclosure, an elastic module for an elastic pad is provided. The elastic module includes: a second elastic body extending in 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 the second elastic body to move relative to the base in the height direction. The present disclosure also provides an elastic component including the elastic module, an elastic pad including the elastic component, and furniture including the elastic pad.

[0010] According to another aspect of the present disclosure, an elastic pad is provided. The elastic pad has an extension plane and a height direction perpendicular to the extension plane. The elastic pad includes a plurality of first elastic modules and a flat base layer within the extension plane. The base layer has an upper surface and a lower surface opposite to the upper surface; and a plurality of retaining pits distributed in an array on the upper surface, each of the retaining pits 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 portion of each first elastic module is inserted into the pit so as to be retained by the base layer. The upper end portion of each first elastic module extends upward and exceeds the upper surface of the base layer. The present disclosure also provides furniture including the elastic pad.

[0011] The elastic assembly and elastic pad formed from the elastic assembly of the present disclosure are easy to assemble. Moreover, in some embodiments, since each elastic assembly is composed of two elastic modules, a variety of different elastic properties can be exhibited by adjusting the elastic coefficient of each elastic module, changing the structure of each elastic module, and the connection and / or positional relationship between the elastic modules.

It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0055] First embodiment:

[0056] Figure 1 and Figure 2 FIG. 1 shows an assembled elastic pad 1000 according to a first embodiment of the present invention. Figure 1 and Figure 2 As shown, the elastic pad 1000 is substantially flat 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 a sofa and provide an elastic support surface to provide a person sitting or lying on the support surface with a comfortable elastic support.

[0057] The elastic pad 1000 may include a main elastic layer 1100 and a first cushion layer 1200 covering the main elastic layer. The main elastic layer 1100 may be made of an elastic material and provide the main source of elasticity for the elastic pad 1000. The first cushion layer 1200 may be located above the main elastic layer 1100 and, during use, be closer to the human body than the main elastic layer 1100. The first cushion layer 1200 may generally have a substantially continuous and flat surface to provide the elastic pad 1000 with a surface more suitable for human contact. The first cushion layer 1200 may also have a certain degree of elasticity to provide an auxiliary source of elasticity for the elastic pad 1000. The first cushion layer 1200 may, for example, be made of sponge or silicone, which also applies to the first cushion layer in other subsequent embodiments.

[0058] The main elastic layer 1100 may include a plurality of elastic components 1110 arranged in an array along the XY plane. Figure 3 The exploded view can be seen more clearly. Figure 3 As shown, each elastic component 1110 in the main elastic layer 1100 may include a first elastic module 1120 extending along the height direction Z and capable of elastically deforming along the height direction Z, and a second elastic module 1130. The first elastic module 1120 can be inserted downwardly along the height direction Z into the corresponding second elastic module 1130 and retained thereby. In other words, the second elastic module 1130 can be both an elastic module and a retaining module for retaining 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 the elastic components 1110 may be connected together to form an elastic base layer 1140 having elasticity along the height direction Z. Figure 4 As shown. The elastic base layer 1140 can be located in the extension plane of the elastic pad (i.e., the XY plane). 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 can have a plurality of retaining pits 1143 distributed in an array on its upper surface, and each retaining pit 1143 is recessed downward from the upper surface 1411 of the elastic base layer 1140. It will be clear below that the retaining pit 1143 can be formed by the accommodating 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 assembly 1110 can be inserted downward from above into the corresponding second elastic module 1130, that is, inserted into the retaining pit 1143 of the elastic base layer 1140, so as to be retained 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 the diagram, Figure 5 Only a portion of the elastic base layer 1140 is shown, and a plurality of first elastic modules 1120 to be inserted into the corresponding second elastic modules 1130 are exemplarily shown. It should be understood that each first elastic module 1120 and its corresponding second elastic module 1130 constitute the aforementioned elastic assembly 1110 (this is in FIG. Figure 5 After all the first elastic modules 1120 are inserted into their corresponding second elastic modules 1130, a Figure 6 The main elastic layer 1100 is shown as being composed of a plurality of elastic components 1110 arranged in an array.

[0060] Finally, if Figure 7 As shown, the first cushion layer 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 resilient pad 1000 is shown.

[0061] Figure 8 and Figure 9 The assembly process of the elastic pad 1000 is more clearly shown in a partially enlarged view. Figure 8 yes Figure 3 The exploded view of FIG. 1 is an enlarged view of area B in the side view along the X direction, wherein the internal structure of the first elastic module 1120 is additionally shown with dotted lines. Once again, it should be understood that each first elastic module 1120 and its corresponding second elastic module 1130 constitute the aforementioned elastic assembly 1110 (this is in FIG. Figure 8 Schematically represented by a rectangular dotted frame 1110). Figure 8 As shown, the second elastic module 1130 of each elastic component 1110 is as shown in FIG. Figure 4 After being connected to form the elastic base layer 1140 as shown, the first elastic module 1120 of each elastic component 1110 can be inserted downwardly 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 7Finally, the first cushion layer 1200 is laid downwardly along the direction indicated by the arrow A on the main elastic layer 1100 composed of the plurality of elastic components 1110 to form a main elastic layer 1100 as shown in FIG. Figure 9 The assembled resilient pad 1000 is shown.

[0062] In order to limit the position of the first cushion layer 1200 relative to the primary elastic layer 1100 thereunder in the horizontal direction (in the plane where the X and Y directions are located), the first cushion layer 1200 may have a plurality of limiting protrusions 1210. Figure 8 During the assembly process, each limiting protrusion 1210 can extend downward along the direction of arrow A into the interior of a corresponding first elastic module 1120, thereby limiting the horizontal movement of the first cushion layer 1200 relative to the main elastic layer 1100. After the assembly is completed, Figure 9 As shown, the first elastic module 1120 of each elastic component 1110 can be held in place by the corresponding second elastic module 1130, and the first cushion layer 1200 can be laid on each elastic component 1110. In particular, Figure 9 The internal structure of the elastic component 1110 located on the far right is also shown by way of example with dotted lines. It can be seen that the limiting protrusion 1210 of the first cushion layer 1200 extends into the interior of the first elastic module 1120, thereby limiting the relative position of the first cushion layer 1200 relative to the elastic component 1110 thereunder.

[0063] In order to more clearly illustrate the first pad layer 1200 with the limiting protrusion 1210, Figure 10 The lower surface 1211 of the first pad 1200 is shown facing upward. Figure 10 The first cushion layer 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 area C of the figure shows more clearly the first elastic module 1120 and the second elastic module 1130 of each elastic component 1110. The first elastic module 1120 can be made of an elastic material so as to be able to provide elastic deformation along the height direction Z. The first elastic module 1120 can be conical or truncated cone in shape as a whole. In the assembled state, the lateral dimension of the first elastic module 1120 gradually decreases from the upper end or the increasing end 1121 to the lower end or the reducing end 1122 along the height direction Z, presenting an inverted cone or truncated cone. The first elastic module 1120 can be hollow and open outward at its increasing end 1121 to form an opening 1123. This hollow and conical or truncated cone-shaped first elastic module 1120 can, on the one hand, provide elastic characteristics that vary due to different sizes along the height direction Z, and on the other hand, can be conducive to storage and transportation in a non-assembled state. As shown in FIG. Figure 12 As shown, one first elastic module 1120 can be inserted into another first elastic module 1120 through the opening 1123 of the enlarged end 1122 of the first elastic module 1120, so that multiple first elastic modules 1120 can be stacked together to reduce storage space.

[0065] Return to see Figure 8 and Figure 9 The first elastic module 1120 may be a bag spring in the form of a conical coil spring wrapped by a flexible material. Figure 13 See more clearly. Figure 13 The internal structure of the first elastic module 1120 is more clearly shown. Figure 13As shown, the coil spring 1124, serving as the elastic body, can taper 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 coil spring 1124 can extend between the outer and inner flexible material layers 1125, 1126. The outer and inner flexible material layers 1125, 1126 are interconnected to form a flexible sheath. The coil spring 1124 can be encapsulated within the flexible sheath in a pre-compressed state (not a completely free state), thereby enabling the resulting first elastic module 1120 to undergo elastic deformation while also maintaining a certain degree of stiffness. This stiffness of the first elastic module can help maintain the shape of the first elastic module 1120 when at rest and help provide a suitable initial hardness or initial support force for the elastic pad 1000. In other embodiments, the flexible sheath encapsulating the coil spring 1124 may be a single layer of flexible material covering the outer surface of the coil spring 1124. In other embodiments, the coil spring 1124 may be pre-compressed in other ways, such as the flexible band used in the second elastic module 1130 described below. In some embodiments, the elastic body of the first elastic module may also be formed in a form or material other than the coil spring 1124, such as a sponge or a plurality of vertically extending leaf springs arranged circumferentially.

[0066] Figure 14 Schematically shows a second elastic module 1130 that can be applied to the elastic component 1110. Figure 14 As shown, the second elastic module 1130 may include a coil spring 1133 capable of elastic deformation. The coil spring 1133 may serve as the elastic body of the second elastic module 1130 and is hollow. The coil spring 1133 may be installed and constrained between the base 1131 and the end cover 1132. The flat base 1131 may be located at the upper end of the second elastic module 1130, and the end cover 1132 may be located at the lower end of the second elastic module 1130. Specifically, the coil spring 1133 may be provided at one end (at Figure 14 The upper end of the middle one abuts against the base 1131, and the other end (the Figure 14 The coil spring 1133 may abut against the end cap 1132 at its upper end, for example, by snap-fitting the coil spring 1133. The abutment or connection between the coil spring 1133 and the base 1131 may be substantially rigid, that is, the movement of the base 1131 and the upper end of the coil spring 1133 along the height direction Z may be synchronized.

[0067] On the outside of the coil spring 1133, a plurality of flexible straps 1134 extend between the base 1131 and the end cover 1132. In this way, by predetermining the length of the flexible strap 1134, the distance between the base 1131 and the end cover 1132 can be limited, thereby constraining the distance between the upper end and the lower end of the coil spring 1133, so that the coil spring 1134 can be constrained between the base 1131 and the end cover 1132 in a pre-compressed state (not a completely free state). With the help of the pre-compressed coil spring 1134, the second elastic module 1130 formed can undergo elastic deformation while having a certain rigidity. The rigidity of the second elastic module 1130 can be beneficial to the shape maintenance of the second elastic module 1130 in a static state, and can provide a suitable initial hardness or initial support force when it is compressed and deformed. In other embodiments, the coil spring 1133 of the second elastic module 1130 can also adopt a similar Figure 13 The bag spring of the first elastic module 1120 is packaged and pre-compressed, and then its upper end is mounted on the base 1131 described above. In appropriate circumstances, the second elastic module 1130 can also adopt an elastic body other than a coil spring, such as a sponge or a leaf spring.

[0068] The base 1131 of the second elastic module 1130 may have a connecting portion 1136 for connecting with the base 1131 of the second elastic module 1130 of another adjacent elastic assembly 1110 during assembly to form, for example, Figure 4 The elastic base layer 1140 shown in FIG. For the convenience of assembly, the bases 1131 of several second elastic modules 1130 can be integrally formed to form a module containing multiple second elastic modules. In this way, during assembly, there is no need to splice the second elastic modules one by one, but only to splice together a smaller number of modules. In fact, Figure 4 The second elastic modules 1130 in each row along the X direction are such a module.

[0069] The second elastic module 1130 and its coil spring 1133 may be tapered or truncated in a direction from the base 1131 to the end cap 1132, and, in the assembled state, the tapered or truncated cone may be inverted. The second elastic module 1130 may be hollow, and its base 1131 may have an opening 1137, so that the second elastic module 1130 has an upwardly open accommodation space 1135. The accommodation space 1135 may be defined by the inner side of the coil spring 1133 and the upper surface of the end cap. Thus, referring to the previous drawings, especially Figures 8-10, it allows the first elastic module 1120 to be inserted from the top downward into the accommodating space 1135 of the second elastic module 1130, so that the first elastic module 1120 can be held by the second elastic module 1130, forming an assembled elastic assembly 1110. The accommodating space 1135 can also be an inverted cone or truncated cone that tapers from the base 1131 to the end cover 1132, so that it can basically form a conical surface with the inverted cone or truncated cone of the first elastic module 1120, so that the second elastic module 1130 can more firmly hold the first elastic module 1120. This can be seen in the following figure. Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 9 .

[0070] As can be seen, this tapered fit between the first elastic module 1120 and the receiving space 1135 of the second elastic module 1130 is particularly convenient for assembly. A simple insertion of the first elastic module 1120 downwardly into the receiving space 1135 of the second elastic module 1130 allows the second elastic module 1130 to retain the first elastic module 1120, thereby assembling the two into the desired elastic assembly 1110 without requiring complex alignment and / or connection operations. This tapered fit also facilitates disassembly of the elastic assembly 1110, wherein the first elastic module 1120 can be separated from the second elastic module 1120 by a single pulling action: pulling the first elastic module 1110 out of the receiving space 1135 of the second elastic module 1120. In other embodiments, the first elastic module 1120 may have an outer surface of other shapes, and the accommodating 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 and at the same time having the aforementioned advantages of easy assembly and disassembly.

[0071] Moreover, since the second elastic module 1130 has a hollow conical or truncated cone shape and the base 1131 at its upper end has an opening 1137, this allows another second elastic module 1130 to be inserted into the accommodation space 1135 in the current second elastic module 1130 through the opening 1137, thereby enabling multiple second elastic modules 1130 to be stacked together in an unassembled state, as shown in FIG. Figure 15 As shown, this facilitates storage and transportation of the second elastic module 1130 in a compact volume in an unassembled state.

[0072] It is also important to note that see Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 9When the first elastic module 1120 is inserted into the second elastic module 1130 and assembled, along the height direction Z, the upper end of the first elastic module 1120 extends outside the accommodation space 1135 of the second elastic module 1130, causing the upper end of the first elastic module 1120 to be higher than the second elastic module 1130. Simultaneously, in a transverse direction perpendicular to the height direction Z, the second elastic module 1130 circumferentially surrounds and holds the first elastic module 1120 on the outside of the first elastic module 1120. Thus, when the elastic pad 1000, particularly the elastic components 1110 in its main elastic layer 1100, is subjected to downward pressure, the first elastic module 1120 directly receives the 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 is shown below. Figure 16 To describe the elastic characteristics of the main elastic layer 1100. Figure 16 As shown, the main elastic layer 1100 may include a plurality of elastic components 1110 arranged in an array in an XY plane. When an elastic component 1110a among the plurality of elastic components 1110 is subjected to a downward pressure F, or when the elastic component 1110a is located at a concentrated point of the pressure F, the elastic component 1110a may undergo a first compression process and optionally a second compression process.

[0074] In the first compression process, the first elastic module 1120a in the elastic assembly 1110a first directly receives the downward pressure F and is significantly compressed downward by it, while the second elastic module 1130a is not compressed downward or is not significantly compressed downward. Specifically, for the first elastic module 1120a having an inverted conical or truncated conical coil spring, see Figure 13 , its upper portion has a relatively small elastic modulus (i.e., is relatively soft) due to its larger diameter, while its lower portion has a relatively large elastic modulus (i.e., is relatively hard) due to its smaller diameter. Thus, under the action of pressure F, the upper portion of the first elastic module 1120a is first significantly compressed. During the first compression process, although the second elastic module 1130a receives pressure transmitted from the first elastic module 1120a due to contact with the first elastic module 1120a, the transmitted pressure is essentially dispersed and acts on the bottom surface and tapered side surfaces of the second elastic module 1130a. The upper end of the second elastic module 1130a does not receive a significant concentrated downward pressure, and thus the second elastic module 1130a is not significantly compressed.

[0075] Also, 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 makes the second elastic modules 1130 not independent, but rather mutually influenced. In this way, when the second elastic module 1130a receives downward pressure, the pressure will be transmitted to the multiple second elastic modules 1130 in the surrounding area through the base 1131, and they will share the pressure. This also ensures that the second elastic module 1130a will not undergo significant deformation during the first compression process. Figure 16 The interconnected bases 1131 of each second elastic module 1130 can actually form an interconnected elastic network (such as the portion surrounded by the dashed box 1150) extending in the XY plane. This interconnected elastic network 1150 is used to interconnect or link the second elastic modules 1130 of each elastic component 1110 in the main elastic layer 1100, 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 elastically deform, the 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 the other elastic components 1110 (especially the second elastic modules 1130) can jointly bear the pressure. In this embodiment, since the base 1131 is located at the upper end of the second elastic module 1130 or the coil spring 1133, relative to the assembled elastic assembly 1110, the base 1131 is located between the upper and lower ends thereof. This also allows the interconnected elastic network 1150 to be located between the upper and lower surfaces of the entire primary elastic layer 1100. In other embodiments, the bases 1131 of only a portion of the second elastic modules 1130 in the primary elastic layer 1100 may be interconnected. The interconnected elastic network 1150 formed in this manner can transmit pressure and / or elastic deformation only between the interconnected second elastic modules 1130, thereby contributing different elastic properties to the primary elastic layer 2100.

[0076] Finally, alternatively or additionally, the second elastic module 1130a itself may have a larger elastic coefficient, such as a harder coil spring 1133, so that the second elastic module 1130a will not be significantly deformed during the first compression process.

[0077] It should be noted that during the first compression process, the elastic deformation of the main elastic layer 1100 is primarily provided by the elastic deformation of the first elastic modules 1120 of the elastic components 1110. Furthermore, the first elastic modules 1120 of each elastic component 1110 are independent of each other, thus exhibiting the distinct elastic characteristics of an independent spring pad.

[0078] If the deformation of the first elastic module 1120a during the first compression process is not sufficient to fully counteract the pressure F, a second compression process may be performed after the first compression process. During the second compression process, the entire elastic assembly 1110a is further compressed downward by the pressure F. At this time, the first elastic module 1120a and the second elastic module 1130a are compressed downward substantially synchronously. Furthermore, as the second elastic module 1130a is compressed downward, its base 1131 immediately transmits the deformation of the second elastic module 1130a directly to the second elastic modules 1130 of other adjacent elastic assemblies 1110, thereby drawing the adjacent second elastic modules 1130 into the fight against 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 to the second elastic module 1130 of the adjacent elastic component 1120 via the interconnected elastic network 1150. The second elastic module 1130 of the adjacent elastic component 1120, which has received the compression deformation, shares the pressure with the current elastic component 1120a. As a result, the second compression process exhibits a higher elastic modulus than the first compression process. In other words, the second compression process of the main elastic layer 1100 feels "harder" than the first compression process.

[0079] Combining the first and second compression processes, it can be seen that the main elastic layer 1100 and the elastic pad 1000 having the same have the following elastic characteristics: 1) showing obvious two-stage elastic characteristics from "soft" to "hard"; and 2) showing obvious independent elastic pad characteristics in the first stage which is "soft", that is, the compression states of different areas of the elastic pad 1000 are independent and do not affect each other.

[0080] Second embodiment:

[0081] Figure 17 and Figure 18 FIG. 2 shows an assembled elastic pad 2000 according to a second embodiment of the present invention. Figure 17 and Figure 18As shown, the elastic pad 2000 is substantially flat, extending in the XY plane, and has a height or thickness extending in the Z direction. The elastic pad 2000 may include a primary elastic layer 2100 and a first cushion layer 2200 covering the primary elastic layer. The primary elastic layer 2100 may be made of an elastic material and provide the primary source of elasticity for the elastic pad 2000. The first cushion layer 2200 may be located above the primary elastic layer 2100, and during use, may be closer to the human body than the primary elastic layer 1100. The first cushion layer 2200 may generally have a substantially continuous and flat surface to provide the elastic pad 2000 with a surface more suitable for human contact. The first cushion layer 2200 may also have a certain degree of elasticity to provide an auxiliary 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. Figure 19 The exploded view can be seen more clearly. 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 undergoing elastic deformation along the height direction Z. The first elastic module 2120 can be inserted downwardly into the corresponding second elastic module 2130 along the height direction Z and be retained thereby. In other words, the second elastic module 2130 can be both an elastic module and a retaining module for retaining 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 portion of the first elastic module 2120 extends into the accommodating space 2135 of the second elastic module 2130 (see FIG. 2 ). Figure 20 ), so that the upper end of the first elastic module 2120 is higher than the second elastic module 2130. Simultaneously, in a lateral direction perpendicular to the height direction Z, the second elastic module 2130 circumferentially surrounds and holds the first elastic module 2120 on the outside of the first elastic module 2120. Thus, when the elastic pad 2000, particularly the elastic components 2110 in its main elastic layer 2100, is subjected to 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 may adopt a shape and structure similar to the first elastic module 1120 in the elastic pad 1000 of the first embodiment, such as Figure 13 The assembly process of the elastic pad 2000 is similar to that of the elastic pad 1000 of the first embodiment. The main difference between the elastic pad 2000 and the elastic pad 1000 lies in the structure of the second elastic module 2130. Apart from this, the above description of the elastic pad 1000 is also basically applicable to the elastic pad 2000.

[0085] Figure 20 Schematically shows a second elastic module 2130 that can be applied to the elastic component 2110. Figure 20 As shown, the second elastic module 2130 may include a coil spring 2133 that can be elastically deformed. The coil spring 2133 may serve as the elastic body of the second elastic module 2130 and is hollow. The coil spring 2133 may be installed and constrained between the annular seat ring 2139 and the end cap 2132. Specifically, the coil spring 2133 may be provided at one end (at Figure 20 The upper end of the center abuts against the seat ring 2139 and is held by it, while the other end (the Figure 20 The lower end portion in the middle) can abut against the end cover 2132. On the outside of the coil spring 2133, a plurality of flexible straps 2134 extend between the seat ring 2139 and the end cover 2132. In this way, by predetermining the length of the flexible strap 2134, the distance between the seat ring 2139 and the end cover 1132 can be limited, so that the coil spring 2134 can be constrained between the seat ring 2139 and the end cover 2132 in a pre-compressed state (not a completely free state). With the help of the pre-compressed coil spring 2134, the second elastic module 2130 formed can undergo elastic deformation while having a certain rigidity. The rigidity of the second elastic module 2130 can be beneficial to the shape maintenance of the second elastic module 2130 in a static state, and can provide a suitable initial hardness 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 method similar to Figure 13 The bag spring of the first elastic module 1120 is packaged and pre-compressed, and then its upper end is mounted on the seat ring 2139. Under appropriate circumstances, the second elastic module 1130 can also adopt an elastic body other than a coil spring, such as a sponge, a leaf spring, etc.

[0086] return Figure 20The flat base 2131 can surround the coil spring 2134 and be positioned below the upper end of the coil spring 2133, or below the seat ring 2139, thus being located vertically (in the height direction Z) between the seat ring 2139 and the end cap 2132. In other words, the base 2131 can be lower than 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 halfway the height of the coil spring 2133 and the upper end. The base 2131 can be connected to the seat ring 2139 located at the upper end of the coil spring 2134 via a flexible member 2138. This allows relative movement between the upper end of the coil spring 2134, or the seat ring 2139, and the base 2131 in the height direction Z. The flexible member 2138 can be elastic, allowing for elastic deformation to transfer force between the seat ring 2139 and the base 2131, 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 member 2138 can be made of the same material and can be integrally formed. In other embodiments, when the seat ring 2139 is omitted, the flexible member 2138 can be directly attached to the base 2131 and the upper end of the coil spring 2133, respectively.

[0087] The base 2131 of the second elastic module 2130 may have a connecting portion 2136 for connecting with the base 2131 of the second elastic module 2130 of another adjacent elastic assembly 2110 during assembly to form, for example, Figure 22 The elastic base layer 2140 shown in FIG. The description of the elastic base layer 2140 can refer to the first embodiment. Figure 4 The description of the elastic base layer 1140 is omitted here. Similar to the first embodiment, for the convenience of assembly, the bases 2131 of the plurality of second elastic modules 2130 can be integrally formed to form a module including a plurality of second elastic modules. Figure 20 As shown, these connecting parts 2136 may include connecting parts 2136a and 2136b with a concave-convex structure, wherein the protrusion 2136a can be inserted into the recess 2136b of the base 2131 of another adjacent second elastic module 2130, and the recess 2136b can receive the protrusion 2136a of the base 2131 of another second elastic module 2130. These connecting parts 2136 may also include "slide rail-slide groove" type connecting parts 2136c and 2136d, wherein the slide rail 2136c can be inserted into the slide groove 2136d of the base 2131 of another adjacent second elastic module 2130, and the slide groove 2136d can receive the slide rail 2136c of the base 2131 of another second elastic module 2130.

[0088] like Figure 20 As shown, the second elastic module 2130 and its coil spring 2133 may have a tapered or truncated cone shape that tapers from the seat ring 2139 to the end cap 2132. In the assembled state, this tapered or truncated cone shape may be inverted. The second elastic module 2130 may be hollow, and its seat ring 2139 may have an opening 2137, thereby providing the second elastic module 1130 with an upwardly open receiving space 2135. This receiving space 2135 may be defined by the inner side of the coil spring 2133 and the upper surface of the end cap 2132. This allows the first elastic module 2120 to be inserted downward from above into the receiving space 2135 of the second elastic module 2130, allowing the second elastic module 2130 to retain the first elastic module 2120, thus forming the assembled elastic assembly 2110. The accommodating space 2135 may also be an inverted cone or truncated cone that tapers in the direction from the seat ring 2139 to the end cover 2132, so that it can basically form a conical surface fit with the inverted cone or truncated cone-shaped first elastic module 2120, so that the second elastic module 2130 can more firmly hold the first elastic module 2120. It can be seen that this conical surface fit between the first elastic module 2120 and the accommodating space 2135 of the second elastic module 2130 is particularly convenient for assembling and disassembling the elastic component 2110. This can be referred to the relevant description of the elastic component 1110 of the first embodiment above and will not be repeated here. In other embodiments, surface fits of other shapes that facilitate assembly and disassembly between the first elastic module 2120 and the accommodating space 2135 of the second elastic module 2130 are also feasible. Moreover, the conical or truncated cone shape of the second elastic module 2130 and its upwardly open accommodating space 2135 also allow multiple second elastic modules 2130 to be stacked on each other, such as Figure 21 As shown, this facilitates storage and transportation of the second elastic module 2130 in a compact volume in an unassembled state. It should be noted that, in order to facilitate stacking, the flexible member 2138 can be extended outward and downward from the upper end of the coil spring 2133.

[0089] Figure 23 yes Figure 17 and Figure 18 The side view of the main elastic layer 2100 in FIG. Figure 23 To describe the elastic characteristics of the main elastic layer 2100. 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 an elastic component 2110a among the plurality of elastic components 2110 is subjected to a downward pressure F, or when the elastic component 2110a is located at a concentrated point of the pressure F, the elastic component 2110a may undergo a first compression process and optionally a second and third compression process.

[0090] During the first compression process, the first elastic module 2120a in the elastic assembly 2110a directly receives the downward pressure F and is significantly compressed downward by it, while the second elastic module 2130a is not compressed downward or is not significantly compressed downward. Specifically, for the first elastic module 2120a having an inverted conical or truncated conical coil spring, its upper portion has a relatively small elastic coefficient (i.e., is relatively soft) due to its larger diameter, while its lower portion has a relatively large elastic coefficient (i.e., is relatively hard) due to its smaller diameter. Thus, under the action of the pressure F, the upper portion of the first elastic module 2120a is significantly compressed first. During the first compression process, although the second elastic module 2130a receives pressure transmitted from the first elastic module 2120a due to contact with the first elastic module 2120a, the transmitted pressure basically acts in a dispersed manner on the bottom surface and conical side surface of the second elastic module 2130a, and the upper end portion of the second elastic module 2130a does not receive obvious concentrated downward pressure, so the second elastic module 1130 will not be significantly compressed.

[0091] Also, see Figure 22 The second elastic modules 2130 of each elastic component 2110 are interconnected at the base 2131 to form an elastic base layer 2140. This means that the second elastic modules 2130 are not independent, but rather have a pulling effect on each other. Thus, if the flexible member 2138 is an elastic member capable of transmitting force, when the second elastic module 2130a receives downward pressure, the pressure is transmitted to the multiple second elastic modules 2130 in the surrounding area via the flexible member 2138 and the base 2131, and the second elastic modules 2130a share 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 itself may have a larger elastic coefficient, such as a harder coil spring 2133, so that the second elastic module 2130a will not be significantly deformed during the first compression process.

[0093] It should be noted that during the first compression process, the elastic deformation of the main elastic layer 2100 is primarily provided by the elastic deformation of the first elastic modules 2120 of the elastic components 2110. Furthermore, the first elastic modules 2120 of each elastic component 2110 are independent of each other, thus exhibiting the distinct elastic characteristics of an independent spring pad.

[0094] If the deformation of the first elastic module 2120a during the first compression process is not sufficient to completely counteract the pressure F, a second compression process may be performed after the first compression process. During the second compression process, the entire elastic assembly 2110a is further compressed downward by the pressure F, and the first elastic module 2120a and the second elastic module 2130a are compressed downward substantially synchronously.

[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 an elastic member, at the beginning of the second compression process, as the second elastic module 2130a is compressed downward, the downward displacement of the seat ring 2139 caused by the deformation of the second elastic module 2130a is significantly absorbed by the flexible member 2138 and is not significantly transmitted to the second elastic modules 2130 of the adjacent elastic components 2110. In other words, during the second compression process, the pressure F is primarily resisted by the deformation of the first elastic module 2120a and the second elastic module 2130a, while the interconnected elastic network 2150 and the adjacent elastic components 2110 do not significantly participate. The primary elastic layer 2110 of the second embodiment exhibits a higher elastic modulus during the second compression process than during the first compression process. In other words, the primary elastic layer 2110 feels "harder" during the second compression process than during the first compression process.

[0096] When the deformation of the first elastic module 2120a and the second elastic module 2130a during the second compression process is not sufficient to completely resist the pressure F, a third compression process may be performed after the second compression process.

[0097] During the third compression process, because the flexible member 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 begins to significantly bear the pressure F and directly transmits the deformation of the second elastic module 2130a to the second elastic modules 2130 of other adjacent elastic assemblies 2110, thereby drawing the adjacent second elastic modules 2130 into the resistance to the pressure F. From the perspective of the interconnected elastic network 2150 formed by the interconnected bases 2131, when the bases 2131 begin to significantly bear the pressure F, the interconnected elastic network 2150 also begins to significantly bear the pressure F. At this point, the interconnected elastic network 2150 significantly participates in the compression process and transmits the pressure F to the second elastic modules 2130 of the adjacent elastic components 2120. These second elastic modules 2130 of the adjacent elastic components 2120, along with the current elastic component 2120a, bear the pressure. As a result, the third compression process exhibits a higher elastic modulus than the second compression process. In other words, the third compression process of the primary elastic layer 2100 feels "harder" than the second compression process.

[0098] See also Figure 23 It should be noted that the interconnected bases 2131 of the second elastic modules 2130 can actually form an interconnected elastic network extending within the XY plane (e.g., the portion surrounded by the dashed box 2150). This interconnected elastic network 2150 is used to interconnect or link the second elastic modules 2130 of the elastic components 2110 in the main elastic layer 2100, 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, causing its second elastic module 2130a to begin to elastically deform, the pressure can be transmitted to other adjacent elastic components 2110 (particularly adjacent elastic components) via the interconnected elastic network 2150, so that the other elastic components 2110 (particularly the second elastic modules 2130) can share the pressure. In this embodiment, since the base 2131 is located at the upper end of the second elastic module 2130 or the coil spring 2133, relative to the assembled elastic assembly 2110, the base 2131 is located between the upper and lower ends thereof. This also allows the interconnected elastic network 2150 to be located between the upper and lower surfaces of the entire primary elastic layer 2100. In other embodiments, the bases 2131 of only a portion of the second elastic modules 2130 in the primary elastic layer 2100 may be interconnected. The interconnected elastic network 2150 formed in this manner can transmit pressure and / or elastic deformation only between the interconnected second elastic modules 2130, thereby contributing different elastic properties to the primary elastic layer 2100.

[0099] From the first to third compression processes, it can be seen that 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 areas of the elastic pad 2000 are independent and do not affect each other.

[0100] In the foregoing 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 can 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. In this way, after only the first elastic module 2120 is compressed, before the first and second elastic modules 2120 and 2130 are synchronously compressed, the interconnected elastic network 2150 composed of the interconnected bases 2131 will get involved, involving other adjacent elastic components 2110 to jointly resist the pressure F. In other words, the interconnected elastic network 2150 will be more Figure 23 The illustrated embodiment operates earlier, so that the elastic pad and the main elastic layer exhibit elastic characteristics different from those of the second embodiment.

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

[0102] Third embodiment:

[0103] Figure 24 and Figure 25 FIG. 3 shows an assembled elastic pad 3000 according to a third embodiment of the present invention. Figure 24 and Figure 25As shown, the elastic pad 3000 is substantially flat, extending in the XY plane, and has a height or thickness extending in the Z direction. The elastic pad 3000 may include a primary elastic layer 3100 and a first cushion layer 3200 covering the primary elastic layer. The primary elastic layer 3100 may be made of an elastic material and provide the primary source of elasticity for the elastic pad 3000. The first cushion layer 3200 may be located above the primary elastic layer 3100 and, during use, be closer to the human body than the primary elastic layer 3100. The first cushion layer 3200 may generally have a substantially continuous and flat surface to provide the elastic pad 3000 with a surface more suitable for human contact. The first cushion layer 3200 may also have a certain degree of elasticity to provide an auxiliary source of elasticity for the elastic pad 3000.

[0104] It should be noted that although the first cushion layer 3200 is basically flat as a whole, this does not exclude the possibility that the upper surface of the first cushion layer 3200 may have concave and / or convex structures 3220 that do not affect the comfort of human contact, and the structure is preferably elastic.

[0105] The main elastic layer 3100 may include a plurality of elastic components 3110 arranged in an array along the XY plane. Figure 26 The exploded view can be seen more clearly. 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 undergoing elastic deformation along the height direction Z. The first elastic module 3120 can be inserted downwardly into the corresponding second elastic module 3130 along the height direction Z and be retained thereby. In other words, the second elastic module 3130 can be both an elastic module and a retaining module for retaining 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 portion of the first elastic module 3120 extends into the accommodating space 3135 of the second elastic module 3130 (see FIG. 3 ). Figure 27 ), so that the upper end of the first elastic module 3120 is higher than the second elastic module 3130. At the same time, in a lateral direction perpendicular to the height direction Z, the second elastic module 3130 can circumferentially surround and retain the first elastic module 3120 on the outside of the first elastic module 3120. In this way, when the elastic pad 3000, particularly the elastic components 3110 in its main elastic layer 3100, is subjected to 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 The assembly process of the elastic pad 3000 is similar to that of the elastic pads 1000 and 2000 of the first and second embodiments. The main difference between the elastic pad 3000 and the elastic pads 1000 and 2000 lies in the structure of the second elastic module 3130. Apart from this, the above description of the elastic pads 1000 and 2000 also generally applies to the elastic pad 3000.

[0108] Figure 27 and Figure 28 Schematically shows a second elastic module 3130 that can be applied to the elastic component 3110. Figure 27 and Figure 28 As shown, the second elastic module 3130 may include a coil spring 3133 capable of elastic deformation. The coil spring 3133 may serve as the elastic body of the second elastic module 3130 and is hollow. Along the height direction Z, the coil spring 3133 may be installed and constrained between the mounting cylinder 3132 and the flat base 3131. The base 3131 may be located at the lower end of the elastic assembly 3110. The mounting cylinder 3132 may be made of a non-elastic material that is not easily deformed and may have a flange 3139 extending laterally outward at its upper end. In this way, the coil spring 3133 may abut against the lower surface of the flange 3139 of the mounting cylinder 3132 at the upper end to support the mounting cylinder, while abutting against the base 3132 at the lower end. The mounting cylinder 3132 extends downward from its flange 3139 inside the coil spring 3133, thereby substantially extending inside the coil 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 can also be connected to the upper end of the coil spring 3133 in other suitable ways.

[0109] To securely hold the coil spring 3133, the base 3131 may have an annular groove 3131a so that the lower end of the coil spring 3133 can be removably inserted into the groove. Outside the coil spring 3133, multiple flexible straps 3134 extend between the mounting tube 3132 and the base 3131. By predetermining the length of the flexible straps 3134, the distance between the mounting tube 3132 and the base 3131 can be limited, allowing the coil spring 3134 to be constrained between the mounting tube 3132 and the base 3131 in a pre-compressed state (not a completely free state). The pre-compressed coil spring 3134 allows the second elastic module 3130 to undergo elastic deformation while maintaining a certain degree of rigidity. This rigidity helps maintain the shape of the second elastic module 3130 when stationary and provides a suitable initial hardness or initial support force when compressed and deformed. The flexible strap 3134 and the mounting barrel 3132 may be made of the same material and may be integrally formed.

[0110] The base 3131 of the second elastic module 3130 may have a connecting portion 3136 for connecting with the base 3131 of the second elastic module 3130 of another adjacent elastic assembly 3110 during assembly to form, for example, Figure 30 The elastic base layer 3140 shown in FIG. The description of the elastic base layer 3140 can refer to the first embodiment. Figure 4 The description of the elastic base layer 1140 is omitted here. Similar to the first embodiment, for the convenience of assembly, the bases 2131 of the plurality of second elastic modules 2130 can be integrally formed to form a module including a plurality of second elastic modules. Figure 27 As shown, these connecting parts 3136 may include "slide rail-slide groove" type connecting parts 3136c and 3136d, wherein the slide rail 3136c can be inserted into the slide groove 3136d of the base 2131 of another adjacent second elastic module 3130, and the slide groove 3136d can receive the slide rail 3136c of the base 3131 of another second elastic module 3130.

[0111] like Figure 27As shown, the coil spring 3133 of the second elastic module 3130 can be tapered or truncated-conical, tapering from the upper end to the lower end along the vertical direction or height direction Z. In the assembled state, this tapered or truncated-conical shape can be upright, unlike the inverted tapered or truncated-conical coil springs 1133 and 2133 in the first and second embodiments. In this case, the mounting cylinder 3132 can provide the required accommodation space 3135 to accommodate the inverted tapered or truncated-conical 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 upward. This allows the first elastic module 3120 to be inserted downward from above into the accommodation space 3135 of the second elastic module 3130, so that the second elastic module 3130 can retain the first elastic module 3120, forming the assembled elastic assembly 3110. The accommodating space 3135 defined by the inner side surface of the hollow mounting cylinder 3132 may also be in the shape of an inverted cone or truncated cone that tapers from the upper end to the lower end in the assembled state. Thus, it can substantially form a conical surface with the inverted cone or truncated cone-shaped first elastic module 3120 in the assembled state, thereby allowing the second elastic module 3130 to more firmly hold the first elastic module 3120. The mounting cylinder 3132 can firmly hold the first elastic module 3120 solely by utilizing this surface engagement with the first elastic module 3130, without requiring any other connection or fixing operations.

[0112] It can be seen that the tapered surface fit between the first elastic module 3120 and the receiving space 3135 of the second elastic module 3130 is particularly convenient for assembling and disassembling the elastic assembly 2110. For details, please refer to the previous description of the elastic assembly 1110 of the first embodiment and will not be repeated here. In other embodiments, other surface shapes that facilitate assembly and disassembly between the first elastic module 3120 and the receiving space 3135 of the second elastic module 3130 are also feasible.

[0113] The second elastic module 3130 as a whole presents a substantially M-shaped cross-section. The outer contour formed by the coil spring 3122 of the second elastic module 3130 is basically a right-set cone or truncated cone, and the inner contour formed by the mounting cylinder 3132 is an inverted cone or truncated cone. Figure 27The cross-sectional view shown in FIG. 31 is more clearly visible. In addition, the base 3131 of the second elastic module 3130 may have an opening 3131b, and the size of the opening 3131b may be larger than the size of the upper end of the second elastic module 3130, for example, it may be larger than the diameter of the annular flange 3139. Since the second elastic module 3130 has a hollow M-shape and the 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 the opening 3131b, thereby enabling multiple second elastic modules 3130 to be stacked together in an unassembled state, as shown in FIG. Figure 29 As shown, this facilitates storage and transportation of the second elastic module 3130 in a compact volume in an unassembled state.

[0114] See also Figure 28 , the dotted line D in the figure represents the plane where the bottom surface of the second elastic module 3130 is located, which is located at the lowest position of the second elastic module 3130. It can be understood that the plane shown by the dotted line D is also the plane where the bottom surface of the elastic component 3110 and the bottom surface of the main elastic layer 3100 are located. Figure 25 and 37 As shown. Return Figure 28 , it can be seen that the vertical position of the lower end of the mounting tube 3132 can be significantly higher than the bottom surface of the second elastic module 3130. In this way, when the mounting tube 3132 is subjected to downward pressure, it can move downward by compressing the coil spring 3133. The mounting tube 3132 can also have an opening 3137L at its lower end. In this way, Figure 31 As shown, when the first elastic module 3120 is inserted into the second elastic module 3130 to form the elastic assembly 3110, the lower end of the first elastic module 3120 first passes through the upper opening 3137U of the mounting cylinder 3132, and then passes 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 predetermining the taper of the first elastic module 3120 and the mounting cylinder 3132, as well as the length of the first elastic module 3120, the lower end of the first elastic module 3120 can be higher than the bottom surface of the second elastic module 3130 or the elastic assembly 3110, as shown by the dotted line D, in the assembled state, or in other words, suspended above the bottom surface.

[0115] Thus, see Figure 31When the elastic assembly 3110 is subjected to a downward pressure F, the first elastic module 3120 directly receives this pressure F and is significantly compressed downward by it. During the compression of the first elastic module 3120, due to its contact with the mounting tube 3132 of the second elastic module 3130, this pressure is quickly transmitted to the tapered side of the mounting tube 3132. Because the mounting tube 3132 and the lower ends of the first elastic module 3120 are suspended in the air, the pressure on the tapered side of the mounting tube 3132 is concentrated at its flange 3139, acting on the upper end of the coil spring 3133. This also places significant downward pressure on the second elastic module 3130, which, together with the first elastic module 3120, counteracts the pressure F. In other words, in this embodiment of the elastic assembly 3110, the first elastic module 3120 and the second elastic module 3130 essentially work together from the outset to counteract the pressure F. This is different from the elastic components 1110 and 2110 in the first and second embodiments, in which during the first compression process, the first elastic modules 1120 and 2120 mainly resist the pressure F, and the second elastic modules 1130 and 2130 do not significantly participate.

[0116] Since the coil spring 3133 of the second elastic module 3130 is in the shape of a right cone or truncated cone, and the coil spring (not shown) of the first elastic module 3130 is in the shape of an inverted cone or truncated cone, and they work together when the elastic component 3110 is subjected to the downward pressure F, the overall elastic performance of the elastic component 3110 is similar to Figure 32 Compared with the first and second embodiments, the first compression process is mainly composed of the following Figure 13 When the inverted conical coil spring 1124 shown is working, the elastic component 3110 of this embodiment will show a softer elastic characteristic at the beginning.

[0117] Furthermore, in this third embodiment, the base 3131 of the second elastic module 3130 is located at the bottom surface (dashed line D) of the entire elastic assembly 3110. Therefore, the connection point between adjacent second elastic modules 3130 is also at the bottom surface of the elastic assembly 3110. This ensures that no other elastic components 3110 are affected during the entire compression process of an elastic component 3110, thereby exhibiting improved elastic characteristics of an independent spring pad compared to the elastic components 1110 and 2110 in the first and second embodiments.

[0118] Compared to a single, concave coil spring, the elastic assembly 3110 can be composed of two independent conical coil springs, namely the first and second elastic modules 3120 and 3130. This allows for a wider range of different elastic properties to be combined by adjusting the elastic characteristics of the two coil springs. Furthermore, the conical shape of the first and second elastic modules 3120 and 3130 facilitates storage of the components in a nested manner. Finally, assembly of the first and second elastic modules 3120 and 3130 is simple: simply insert the first elastic module 3120 into the second elastic module 3130 from above.

[0119] Other embodiments:

[0120] Figure 33 The elastic component 4110 of another embodiment is schematically shown. Figure 33 As shown, similar to the elastic assemblies 1110, 2110, and 3110 in the first to third embodiments, the elastic assembly 4110 may include a first elastic module 4120 and a second elastic module 4130 capable of elastically deforming 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 a transverse direction perpendicular to the height direction Z, the second elastic module 4130 may circumferentially surround the first elastic module 4130 on the outside of the first elastic module 4120. In other words, 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 assemblies 1110, 2110, and 3110 in the first to third embodiments, the first and second elastic modules 4130 and 4130 of the elastic assembly 4110 do not have a mutually retaining relationship. Thus, when the elastic assembly 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 downward, while the second elastic module 4130 is not. In other words, during the first compression process, the deformation of the elastic assembly 4110 in the height direction Z is entirely provided by the deformation of the first elastic module. Once the first elastic module 4120 has been significantly compressed for a certain distance, for example, when its upper end is substantially flush with the upper end of the second elastic module 4130, the second compression process begins. During the second compression process, the second elastic module 4130 and the first elastic module 4120 directly receive the pressure and are simultaneously compressed downward. 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's important to note that, whereas during the first compression process, only the first elastic module 4120 resisted pressure, during the second compression process, the first and second elastic modules 4120 and 4130 jointly resisted pressure. Therefore, the elastic assembly 4110 as a whole exhibits a higher elastic modulus during the second compression process than during the first compression process. This makes the elastic assembly 4110 and the elastic pad it forms feel "harder" during the second compression process. In this way, the elastic assembly 4110 can also provide a two-stage elastic characteristic, from "soft" to "hard."

[0123] Figure 34 Another embodiment of an elastic assembly 5110 is schematically shown. This differs from elastic assembly 4110 in that a taller first elastic module 5120 is an outer elastic module, and a shorter second elastic module 5130 is an inner elastic module. The compression process and elastic characteristics of elastic assembly 5110 are similar to those of elastic assembly 4110.

[0124] Figure 33 and Figure 34 The elastic modules of the elastic components 4110 and 5110 shown can be coil springs with equal diameters along the height direction Z, or can be bag springs made of flexible material coated on the outside of the coil springs. During assembly, the outer elastic modules 4130 and 5120 are simply placed on the outside of the inner elastic modules 4120 and 5130. Although not shown, the elastic components 4110 and 5110 can also have a base so that adjacent elastic components can be connected to each other when assembling 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. A first cushion layer such as that of the first to third embodiments is laid on top of the main elastic layer to assemble the desired elastic pad.

[0125] In the elastic components of the first to third embodiments, the first elastic module is generally conical or truncated-conical, and the second elastic module's accommodation space for holding the first elastic module is also generally conical or truncated-conical. In other embodiments, the accommodation space and the first elastic module may not be tapered as a whole, but may each have a tapered portion. The tapered portion of the accommodation space of the second elastic module holds the corresponding tapered portion of the first elastic module, essentially forming a conical surface fit. Having only localized tapered portions may hinder the compact storage and transportation of the first and second elastic modules in a nested manner, but it is still feasible for manufacturing and selling integrated elastic pads.

[0126] In one embodiment, the elastic component may include a first elastic module extending in the height direction of the elastic pad and a retaining module for retaining the first elastic module. The retaining module may be formed with an upwardly open accommodation space to allow the first elastic module to be inserted from above into the accommodation space and thereby retain the first elastic module. When the first elastic module has been inserted into the accommodation space of the retaining module and retained by it, the upper end of the first elastic module may extend upward out of the accommodation space and be higher than the retaining module, so that when the elastic component is subjected to downward pressure, the first elastic module first receives the pressure. The first elastic module may be selected from one of the first elastic modules described in the above embodiments. The retaining module may be elastic and may be selected from one of the second elastic modules described in the above embodiments that can be elastically deformed in the height direction of the elastic pad. The elastic component thus formed is as described in the first to third embodiments.

[0127] The retaining module may also be non-elastic. For example, the retaining module may have the characteristics of the retaining effect of the second elastic module (such as an accommodating space, etc.), while the elastic characteristics of the second elastic module (such as a coil spring, etc.) may be omitted. In some embodiments, the retaining module may be in the form of a retaining seat formed by a material that is not easily deformed, and has an accommodating space for retaining the first elastic module as described above. Such a retaining module is a basically rigid module, which does not basically deform along the height direction Z. It should be understood that the elastic component composed of such a retaining module also has the advantages of convenient assembly and disassembly of the elastic components described in the first and third embodiments, that is, the elastic component can be assembled and disassembled by a simple single insertion or pull-out action.

[0128] by Figure 31 Taking the elastic assembly 3110 shown as an example, in order to ensure that the retaining module (here, the second elastic module 3130) can firmly retain 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 is preferably no more than 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 assemblies in the first and second embodiments, as well as elastic assemblies 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 a first and a second elastic module. The elastic pad may be the elastic pad 1000, 2000 of the first and second embodiments, wherein the interconnected elastic network may be formed by interconnected bases 1131, 2131, such as Figure 16 and27 In other embodiments, the interconnected elastic network can be other structures that are independent of the base. For example, Figure 20 The base 2131 and the flexible member 2138 of the second elastic module 2130 shown in the figure are omitted, and the seat rings 2139 of the adjacent second elastic modules are connected to each other by connecting members during assembly, thereby forming an Internet. Figure 33 The elastic component 4110 shown, when a plurality of such elastic components 4110 are densely arranged in an array, can form a main elastic layer 4100, such as Figure 35 As shown. It is necessary to understand that for the clarity of the diagram, Figure 35 Only a small number of elastic components 4110 are shown. On the bottom surface of the primary elastic layer 4100, adjacent second elastic modules 4130 of elastic components 4110 in directions parallel to and perpendicular to the paper can be locally connected by bonding, welding, or other methods. Black dots are used in the figure to schematically indicate the connection locations. This connection method can also form the desired 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 within its extension 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 pits distributed in an array on its upper surface, each retaining pit being 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 may be elastically deformed along the height direction. The lower end of each first elastic module may be inserted into a pit of the base layer so as to be retained by the base layer. The upper end of each first elastic module may extend upward and extend beyond the upper surface of the base layer. The base layer may be elastic along the height direction Z, and such a base layer may be, for example, the elastic base layers 1140, 2140, 3140 in the first to third embodiments. Such an elastic base layer is formed by a plurality of second elastic modules 1130, 2130, 3130 extending in the height direction Z, connected to each other within the extension plane XY, and the accommodation space therein forms the retaining pit in this embodiment. For example, see Figure 4, the accommodation space 1135 of the second elastic module 1130 is also the retaining pit 1143 of the elastic base layer 1140. The specific structure of the second elastic module can be found in the description above and will not be repeated here. It should be understood that the second elastic body of the second elastic module 1130, 2130, 3130 constituting the elastic base layer 1140, 2140, 3140 can be a coil spring 1133, 2133, 3133 extending in the height direction, which makes the elastic base layer 1140, 2140, 3140 actually a spring net with a certain thickness. In other embodiments, the base layer can adopt other suitable forms of spring nets.

[0131] In another embodiment, the base layer can also be made of other elastic materials integrally formed, and the elastic material can be, for example, sponge, silicone, rubber, etc. Figure 36-Figure 39 shown. Figure 36 The base layer 6140 is shown in FIG. , and the base layer 6140 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 pits 6143 distributed in an array on its upper surface 6141, each retaining pit 6143 being recessed from the upper surface 6141 of the base layer 6140 toward the inside of the body 6144, that is, recessed downward toward the lower surface 6142. The retaining pit 6143 may have an inverted cone or truncated cone shape, that is, its lateral dimension gradually decreases along the direction from the upper surface 6141 to the lower surface 6142, which is Figure 37 This conical or truncated cone shape of the retaining recess 6143 is particularly suitable for retaining the inverted conical or truncated cone 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 can be elastically deformed along the height direction Z. Each first elastic module 6120 corresponds to a retaining pit 6143, and the lower end of the first elastic module 6120 can be inserted into the corresponding retaining pit 6143 in the base layer 6140 so as to be retained by the base layer 6140. Figure 39As shown, when the first elastic module 6120 has been inserted into the retaining recess 6143, the upper end of the first elastic module 6120 can extend upward to the outside of the retaining recess 6143, that is, extend beyond the upper surface 6143 of the base layer 6140. The first cushion layer 6200 is laid on the array of the first elastic modules 6120 to form the elastic pad 6000. The first elastic module 6120 can be similar to the first elastic module of the aforementioned embodiments, such as the 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 non-elastic, thereby 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 non-elastic material.

[0132] like Figure 40 As shown, the elastic pads of the aforementioned embodiments, after being wrapped in an outer cover, can be placed on a bed support frame to form a bed. In other embodiments, the elastic pads of the aforementioned embodiments can also be placed directly on the ground to serve as a bed under appropriate circumstances. In other embodiments, the elastic pads of the aforementioned embodiments can be placed on a sofa frame to form a desired sofa.

[0133] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
