Abstract

The present disclosure provides an elastic assembly for an elastic pad, including a first elastic module extending in a height direction of the elastic pad and a holding module for holding the first elastic module. The holding module is formed with an upwardly open receiving space to allow the first elastic module to be inserted into the receiving space of the holding module from above downward and thereby hold the first elastic module. In a state in which the first elastic module has been inserted into and held by the accommodation space of the holding module, an upper end portion of the first elastic module extends upward out of the accommodation space and is higher than the holding module so that the pressure is first received by the first elastic module when the elastic assembly is subjected to downward pressure. The present disclosure also provides an elastic pad including the elastic assembly, and furniture including the elastic pad.

Description

Elastic pad and elastic assembly for elastic pad

Technical Field

The present disclosure relates to the field of furniture, and in particular to resilient pads and resilient assemblies thereof for use with furniture such as beds or sofas.

Background

Furniture such as beds or sofas often have resilient pads for improved sitting or lying comfort. Various resilient pads are known in the art, such as foam pads, spring pads, and the like. Conventional resilient pads are typically unitary and inconvenient to handle. Accordingly, it is desirable to have a resilient pad that is convenient for the user to assemble by himself.

As for spring mats, various proposals have been made in the prior art to improve the comfort thereof, such as spring mats made up of individual pocket springs, spring mats made up of individual spring modules, and the like. However, the resilient characteristics that these spring pads can provide remain limited. It is desirable to have more resilient pads with different resilient characteristics available.

Disclosure of Invention

The present disclosure at least partially addresses or alleviates the above-mentioned deficiencies in the prior art.

According to one aspect of the present disclosure, an elastic assembly for an elastic pad is provided. The elastic assembly comprises a first elastic module and a second elastic module which extend along the height direction of the elastic pad and can elastically deform along the height direction. In a transverse direction perpendicular to the height direction, one of the first and the 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 the circumferential direction thereof outside the inner elastic module. The upper end of the first elastic module is higher than the second elastic module along the height direction, so that when the elastic assembly is subjected to downward pressure, the first elastic module firstly 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 assembly, and furniture including the elastic pad.

According to yet another aspect of the present disclosure, an elastic assembly for an elastic pad is provided. The elastic assembly includes a first elastic module extending in a height direction of the elastic pad and a holding module for holding the first elastic module. The holding module is formed with an upwardly open receiving space to allow the first elastic module to be inserted into the receiving space of the holding module from above downward and thereby hold the first elastic module. In a state in which the first elastic module has been inserted into and held by the accommodation space of the holding module, an upper end portion of the first elastic module extends upward out of the accommodation space and is higher than the holding module so that the pressure is first received by the first elastic module when the elastic assembly is subjected to downward pressure. The present disclosure also provides an elastic pad including the elastic assembly, and furniture including the elastic pad.

According to yet another aspect of the present disclosure, an elastic pad is provided. The elastic pad includes a primary elastic layer that provides a primary source of elasticity. The main elastic layer includes a plurality of elastic members arranged in an array in an extension plane perpendicular to a height direction of the elastic pad. Each elastic assembly comprises a first elastic module and a second elastic module, wherein the first elastic module extends along the height direction of the elastic pad and can elastically deform along the height direction, and the second elastic module surrounds the first elastic module along the circumferential direction of the second elastic module outside the first elastic module. The upper end of the first elastic module is higher than the second elastic module in the height direction, so that when the elastic assembly receives downward pressure from the outside of the elastic pad, the pressure is directly received by the first elastic module first, and then the pressure is directly received by the second elastic module or the downward pressure transmitted by the first elastic module is indirectly received. The primary elastic layer further comprises an interconnecting elastic web. The interconnected elastic webs extend in a plane perpendicular to the height direction and are located between the upper and lower surfaces of the primary elastic layer. The interconnected elastic web is connected to the second elastic modules of at least a part of the plurality of elastic assemblies for transmitting the pressure and/or elastic deformation between the second elastic modules interconnected by the interconnected elastic web. When any one of the second elastic modules of the at least one part of elastic assembly is elastically deformed by the pressure, the pressure is transmitted to the other connected second elastic modules via the interconnection elastic net so as to be borne by the second elastic modules connected to each other together. The present disclosure also provides furniture including the resilient pad.

According to yet another aspect of the present disclosure, a holding module for an elastic pad is provided for holding a first elastic module and forming an elastic assembly extending in a height direction of the elastic pad together therewith. The holding module comprises a second elastic body capable of elastically deforming along the height direction; and a mounting cylinder supported by the second elastic body. The mounting cylinder is hollow, and an inner surface thereof defines a receiving space for receiving the first elastic module. The receiving space of the mounting cylinder extends in the height direction and is opened upward to allow the first elastic module to be inserted downward into the receiving space of the mounting cylinder from above and thereby hold the first elastic module. Downward or upward movement of the mounting cylinder can compress or release the second resilient body, respectively. The present disclosure also provides an elastic assembly including the retention module, an elastic pad including the elastic assembly, and furniture including the elastic pad.

According to yet 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 a height direction of the elastic pad and having opposite upper and lower ends, and elastically deformable in the height direction; a flat base surrounding the second elastic body and located between the upper end portion and the lower end portion 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 relatively move with respect to the base in the height direction. The present disclosure also provides an elastic assembly including the elastic module, an elastic pad including the elastic assembly, and furniture including the elastic pad.

According to yet 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 comprises a plurality of first elastic modules and a flat base layer in the extension plane. The base layer has an upper surface and a lower surface opposite the upper surface; and a plurality of retaining pockets distributed in an array at the upper surface, each of the retaining pockets recessed downwardly from the upper surface of the base layer. The plurality of first elastic modules extend in the height direction of the elastic pad and are elastically deformable in the height direction. The lower end of each of the first elastic modules is inserted into the recess so as to be held by the base layer. The upper end of each first elastic module extends upwards and exceeds the upper surface of the base layer. The present disclosure also provides furniture including the resilient pad.

The elastic assembly and the elastic pad formed by the elastic assembly are easy to assemble. Moreover, in some embodiments, since each elastic assembly is composed of two elastic modules, by adjusting the elastic coefficient of each elastic module, the respective structural changes of the elastic modules, and the connection and/or positional relationship between the elastic modules, respectively, a variety of different elastic characteristics may be exhibited.

Detailed Description

In order to better understand the technical solutions of the present disclosure, the following description will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. It will be apparent that the described embodiments are merely embodiments of a portion, but not all, of the present disclosure. All other embodiments, which can be made by one of ordinary skill in the art without inventive effort, based on the embodiments in this disclosure, shall fall within the scope of the present disclosure.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

First embodiment:

fig. 1 and 2 show an assembled resilient pad 1000 according to a first embodiment of the invention. As shown in fig. 1 and 2, the spring pad 1000 is substantially flat extending in the X-Y plane and has a height or thickness extending in the Z-direction. Typically, the resilient pad 1000 may be applied to a bed or sofa and provides a resilient support surface to provide a comfortable resilient support for a person sitting or lying on the support surface.

The resilient pad 1000 may include a primary resilient layer 1100 and a first cushion layer 1200 overlying the primary resilient layer. The primary elastic layer 1100 may be made of an elastic material and provides a primary source of elasticity for the elastic pad 1000. The first cushion layer 1200 may be positioned above the primary elastic layer 1100, closer to the human body than the primary elastic layer 1100 is in use. First cushion layer 1200 may generally have a substantially continuous and planar surface to provide resilient cushion 1000 with a surface that is more suitable for human contact. The first cushion 1200 may also have some degree of elasticity to provide an additional source of elasticity to the resilient cushion 1000. The first cushion 1200 may be made of, for example, sponge or silica gel, as is also applicable to the first cushion in other embodiments that follow.

The primary elastic layer 1100 may include a plurality of elastic members 1110 arranged in an array along an X-Y plane. The structure of the resilient pad 1000 and the resilient assembly 1110 can be seen more clearly in the exploded view of fig. 3. As shown in fig. 3, each elastic assembly 1110 in the main elastic layer 1100 may include a first elastic module 1120 and a second elastic module 1130 that extend in the height direction Z and are elastically deformable in the height direction Z. The first elastic modules 1120 can be inserted downward into and held by the corresponding second elastic modules 1130 in the height direction Z. That is, the second elastic module 1130 may 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 assembly 1110 may be independent of each other, while the second elastic modules 1130 of adjacent elastic assemblies 1110 may be connected to each other.

In assembly, the second elastic modules 1130 of the respective elastic assemblies 1110 may be first connected to each other to form an elastic base layer 1140 having elasticity in the height direction Z, as shown in fig. 4. The elastic base layer 1140 may lie in the plane of extension of the elastic pad (i.e., the X-Y plane). The resilient base layer 1140 is flat and has an upper surface 1141 and a lower surface 1142 opposite the upper surface 1141. The resilient base layer 1140 may have a plurality of retaining pockets 1143 at an upper surface thereof in an array, each retaining pocket 1143 being recessed downwardly from an upper surface 1411 of the resilient base layer 1140. As will be apparent hereinafter, the holding recess 1143 may be formed by the receiving space 1135 of the second elastic module 1130 for holding the corresponding first elastic module 1120. Then, as shown in fig. 5 and 6, the lower end portion of the first elastic module 1120 of each elastic assembly 1110 may be inserted into the corresponding second elastic module 1130 from above downward, that is, into the holding 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 may extend upward beyond the second elastic module 1130, or beyond the upper surface 1141 of the elastic base layer 1140. For clarity of illustration, only a portion of the elastic base layer 1140 is shown in fig. 5, and a number of first elastic modules 1120 to be inserted into corresponding second elastic modules 1130 are illustratively shown. It is to be understood that each first elastic module 1120 and its corresponding second elastic module 1130 constitute the aforementioned elastic assembly 1110 (this is schematically represented by a rectangular dashed box 1110 in fig. 5). After all the first elastic modules 1120 are inserted into the respective corresponding second elastic modules 1130, a main elastic layer 1100 shown in fig. 6, which is composed of a plurality of elastic members 1110 arranged in an array, may be formed.

Finally, as shown in fig. 7, a first cushion layer 1200 may be laid over the primary elastic layer 1100 comprised of the assembled elastic components 1110 to form the assembled elastic cushion 1000 shown in fig. 1 and 2.

Fig. 8 and 9 more clearly show the assembly process of the elastic pad 1000 in a partially enlarged manner. Fig. 8 is an enlarged view of a region B in a side view seen in the X direction in the exploded view of fig. 3, wherein the internal structure of the first elastic module 1120 is additionally shown with a dotted line. Again, it is to be understood that each first elastic module 1120 and its corresponding second elastic module 1130 constitute the aforementioned elastic assembly 1110 (this is schematically represented by the rectangular dashed box 1110 in fig. 8). As shown in fig. 8, after the second elastic module 1130 of each elastic assembly 1110 is connected into the elastic base layer 1140 as shown in fig. 4, the first elastic module 1120 of each elastic assembly 1110 may be inserted downward into the second elastic module 1130 in the direction indicated by the arrow a (i.e., the height direction Z as described above) to form the main elastic layer 1100 shown in fig. 1, 2, 6, and 7. Finally, a first cushion layer 1200 is laid down over the primary elastic layer 1100 of the plurality of elastic members 1110 in the direction indicated by arrow a, forming an assembled elastic cushion 1000 as shown in fig. 9.

To define the position of the first cushion layer 1200 in the horizontal direction (in the plane of the X and Y directions) relative to the underlying primary elastic layer 1100, the first cushion layer 1200 may have a number of stop protrusions 1210. Referring to fig. 8, during assembly, each of the limiting protrusions 1210 may extend downward into the interior of a corresponding one of the first elastic modules 1120 in the direction of arrow a, so that the first cushion 1200 may be limited from moving in a horizontal direction with respect to the main elastic layer 1100. After assembly, as shown in fig. 9, the first elastic module 1120 of each elastic assembly 1110 may be held in place by a corresponding second elastic module 1130, and the first cushion 1200 may be laid over each elastic assembly 1110. In particular, fig. 9 also illustrates, by way of example, the internal structure of the resilient assembly 1110 on the far right side in phantom, it being seen that the stop projection 1210 of the first cushion 1200 extends into the interior of the first resilient module 1120, thereby defining the relative position of the first cushion 1200 with respect to the resilient assembly 1110 thereunder.

To more clearly illustrate the first cushion 1200 with the spacing protrusions 1210, the lower surface 1211 of the first cushion 1200 is shown facing upward in fig. 10. Referring to fig. 10, the first pad layer 1200 may include a flat-shaped main body 1220. The main body 1220 has a lower surface 1221 facing downwards in the assembled state. Adjacent the edge of the main body 1220, a number of stop bumps 1210 extend outwardly from the lower surface 1221 of the main body 1220.

Fig. 11 is an enlarged view of the area C of fig. 5, which more clearly shows the first elastic module 1120 and the second elastic module 1130 of each elastic assembly 1110. The first elastic module 1120 may be made of an elastic material so as to be able to provide elastic deformation occurring in the height direction Z. The first elastic module 1120 may be tapered or frustoconical in shape as a whole. In the assembled state, the lateral dimension of the first elastic module 1120 tapers in the height direction Z from an upper or enlarged end 1121 to a lower or reduced end 1122, assuming an inverted conical or frustoconical shape. The first elastic module 1120 may be hollow and open outwardly at its enlarged end 1121, forming an opening 1123. Such a hollow and conical or frustoconical first elastic module 1120 can, on the one hand, provide varying elastic characteristics due to the different dimensions along the height direction Z and, on the other hand, can facilitate storage and transport in the unassembled state. As shown in fig. 12, one first elastic module 1120 may be inserted into the inside of another first elastic module 1120 through the opening 1123 of the enlarged end 1122 of the first elastic module 1120, so that a plurality of first elastic modules 1120 may be stacked on each other to reduce a storage space.

Referring back to fig. 8 and 9, the first elastic module 1120 may be in the form of a pocket spring of conical coil spring wrapped with a flexible material, as best seen in fig. 13. The internal structure of the first elastic module 1120 is more clearly shown in fig. 13. As shown in fig. 13, the coil spring 1124 as an elastic body may 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 may be formed of an outer flexible material layer 1125 and an inner flexible material layer 1126, respectively, and the coil spring 1124 may extend between the outer flexible material layer 1125 and the inner flexible material layer 1126. The outer and inner flexible material layers 1125, 1126 are interconnected to form a flexible sleeve. The coil spring 1124 may be encapsulated within the flexible sleeve in a pre-compressed state (not fully free state) such that the resulting first elastic module 1120 is elastically deformable while having a stiffness. The stiffness of the first elastic module may facilitate shape retention of the first elastic module 1120 in a resting state and may help provide the elastic pad 1000 with a suitable initial stiffness or initial support force. In other embodiments, the flexible sleeve encasing the coil spring 1124 may also be a single layer of flexible material covering the outer surface of the coil spring 1124. In other embodiments, the coil spring 1124 may also be pre-compressed in other ways, such as in the manner of a flexible strap for the second elastic module 1130 described below. In some embodiments, the elastic body of the first elastic module may also take other forms or materials than the coil spring 1124, such as a sponge or a plurality of vertically extending elongated leaf springs arranged in a circumferential direction, or the like.

Fig. 14 schematically illustrates a second elastic module 1130 that can be adapted for use with the elastic assembly 1110. As shown in fig. 14, the second elastic module 1130 may include a coil spring 1133 capable of elastic deformation. The coil spring 1133 may serve as an elastic body of the second elastic module 1130, and is hollow. The coil spring 1133 may be mounted and constrained between the base 1131 and the end cap 1132. A flat base 1131 may be located at an upper end of the second elastic module 1130, and an end cap 1132 may be located at a lower end of the second elastic module 1130. Specifically, the coil spring 1133 may abut against the base 1131 at one end (upper end in fig. 14) thereof, and may abut against the end cap 1132 at the other end (lower end in fig. 14). The coil spring 1133 may also be connected to the base 1131 at its upper end, for example, by snap-fitting. 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 in the height direction Z may be synchronized.

On the outside of the coil spring 1133, a plurality of flexible straps 1134 extend between the base 1131 and the end cap 1132. In this way, by predetermining the length of the flexible strap 1134, the distance between the base 1131 and the end cap 1132 may be limited, thereby constraining the distance between the upper and lower ends of the coil spring 1133 such that the coil spring 1134 may be constrained between the base 1131 and the end cap 1132 in a pre-compressed state (not fully free state). The second elastic module 1130 is formed to be elastically deformed while having a certain rigidity by means of the pre-compressed coil spring 1134. The stiffness of the second resilient module 1130 may facilitate shape retention of the second resilient module 1130 in a resting state and may provide a suitable initial stiffness or initial support force when it is compressively deformed. In other embodiments, the coil spring 1133 of the second elastic module 1130 may be packaged and precompressed in a manner similar to the bag spring of the first elastic module 1120 shown in fig. 13, and then the upper end portion thereof is mounted to the base 1131 as described above. The second elastic module 1130 may also employ an elastic body of a non-coil spring, such as a sponge, a plate spring, etc., where appropriate.

The base 1131 of the second elastic module 1130 may have a connection 1136 for interconnecting with the base 1131 of the second elastic module 1130 of an adjacent other elastic assembly 1110 during assembly to form an elastic base layer 1140 such as shown in fig. 4. For convenience of assembly, the bases 1131 of the plurality of second elastic modules 1130 may be integrally formed to form a module including the plurality of second elastic modules. Thus, when assembling, the second elastic modules are not required to be spliced one by one, but only a smaller number of modules are required to be spliced together. In fact, the second elastic module 1130 of each row in the X direction in fig. 4 is one such module.

The second resilient module 1130 and its coil spring 1133 may be tapered conical or frustoconical in the direction from the base 1131 to the end cap 1132, and in the assembled state, may be inverted. The second elastic module 1130 may be hollow, and the base 1131 thereof may have an opening 1137 such that the second elastic module 1130 has an upwardly open receiving space 1135. The receiving space 1135 may be defined by an inner side of the coil spring 1133 and an upper surface of the end cap. Thus, referring to the previous figures, and in particular to fig. 8-10, the first elastic module 1120 is allowed to be inserted into the receiving space 1135 of the second elastic module 1130 from the top downward, so that the first elastic module 1120 can be held by the second elastic module 1130, forming an assembled elastic assembly 1110. The receiving space 1135 may also be an inverted cone or truncated cone tapered in a direction from the base 1131 to the end cap 1132, and thus may be formed substantially in conical fit with the first elastic module 1120 of the inverted cone or truncated cone, so that the second elastic module 1130 may more firmly hold the first elastic module 1120, which may be seen in fig. 1, 2, 6, 7 and 9.

It can be seen that this tapered fit between the receiving space 1135 of the first resilient module 1120 and the second resilient module 1130 is particularly convenient for assembly. A simple single insertion action, with the first elastic module 1120 inserted from above down into the receiving space 1135 of the second elastic module 1130, is required to retain the second elastic module 1130 in the first elastic module 1120, thereby assembling them into the desired elastic assembly 1110 without complicated alignment and/or connection operations. This taper fit also facilitates removal of the elastic assembly 1110, wherein the first elastic module 1120 is disengaged from the second elastic module 1120 using a single pulling action of 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 other shaped outer surfaces, 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-tapered surface fits, while having the aforementioned advantages of easy assembly and disassembly.

Moreover, since the second elastic module 1130 has a hollow tapered or truncated cone shape and the base 1131 at the upper end thereof has an opening 1137, this allows another second elastic module 1130 to be inserted into the receiving space 1135 in the current second elastic module 1130 through the opening 1137, so that the plurality of second elastic modules 1130 can be stacked on each other in the unassembled state, as shown in fig. 15, which facilitates storage and transportation of the second elastic modules 1130 in a compact volume in the unassembled state.

It should be further noted that, referring to fig. 1, 2, 6, 7 and 9, in an assembled state in which the first elastic module 1120 is inserted into the second elastic module 1130, an upper end portion of the first elastic module 1120 is protruded out of the receiving space 1135 of the second elastic module 1130 in the height direction Z such that the upper end portion of the first elastic module 1120 is higher than the second elastic module 1130. Meanwhile, in the lateral direction perpendicular to the height direction Z, the second elastic module 1130 circumferentially surrounds and holds the first elastic module 1120 outside the first elastic module 1120. Thus, when the resilient pad 1000, and in particular each resilient member 1110 in its primary resilient layer 1100, is subjected to downward pressure, the pressure is received directly by the first resilient module 1120 and the downward pressure transmitted by the first resilient module 1120 is received indirectly by the second resilient module 1130.

Fig. 16 is a side view of the primary elastic layer 1100 of fig. 6, and the elastic characteristics of the primary elastic layer 1100 will be described below with reference to fig. 16. As shown in fig. 16, the primary elastic layer 1100 may include a plurality of elastic members 1110 arrayed in an X-Y plane. In the case where one elastic member 1110a of the plurality of elastic members 1110 is subjected to a downward pressure F, or the elastic member 1110a is located at a concentration point of the pressure F, the elastic member 1110a may perform a first compression process and optionally a second compression process.

In the first compression process, the first elastic module 1120a in the elastic assembly 1110a first directly receives the downward pressure F and is compressed significantly downward by it, while the second elastic module 1130a is not or not compressed significantly downward. Specifically, for the first elastic module 1120a having an inverted cone or truncated cone coil spring, see fig. 13, an upper portion thereof has a relatively small elastic coefficient (i.e., relatively soft) due to a large diameter, and a lower portion thereof has a relatively large elastic coefficient (i.e., relatively hard) due to a small diameter. In this way, the upper portion of the first elastic module 1120a is first significantly compressed by the pressure F. During the first compression, although the second elastic module 1130a receives the pressure transferred from the first elastic module 1120a due to the contact with the first elastic module 1120a, the transferred pressure acts substantially dispersedly on the bottom surface and the tapered side surface of the second elastic module 1130a, and the upper end portion of the second elastic module 1130a does not receive the significantly concentrated downward pressure, whereby the second elastic module 1130a is not significantly compressed.

Furthermore, referring to FIG. 4, the second elastic modules 1130 of each elastic assembly 1110 form an elastic base layer 1140 by interconnecting at the base 1131, which allows for the second elastic modules 1130 to be not independent of each other, but rather have a interrelated effect. Thus, when the second elastic module 1130a receives downward pressure, the pressure is transferred to the plurality of second elastic modules 1130 of the surrounding area via the base 1131 and bears the pressure together with them. This also allows the second resilient module 1130a to not deform significantly during the first compression process. Returning to fig. 16, the interconnected bases 1131 of the respective second elastic modules 1130 may actually form an interconnected elastic web (e.g., the portion surrounded by the dashed box 1150) extending in the X-Y plane. The interconnecting elastic web 1150 is used to interconnect or link the second elastic modules 1130 of each elastic assembly 1110 in the primary elastic layer 1100 to transfer pressure and/or elastic deformation between the interconnected second elastic modules 1130 to form the aforementioned interaction. In this way, when the elastic component 1110a is compressed to such an extent that its second elastic module 1130a begins to elastically deform, pressure can be transferred to the second elastic modules 1130 of the other elastic components 1110 (particularly adjacent elastic components) via the interconnecting elastic web 1150, so that the other elastic components 1110 (particularly the second elastic modules 1130) can bear the pressure together. In the present embodiment, since the base 1131 is located at the upper end of the second elastic module 1130 or the coil spring 1133, the base 1131 is located between the upper end and the lower end thereof with respect to the assembled elastic assembly 1110, which also enables the interconnection elastic web 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 primary elastic layer 1100 may be interconnected, and the thus-formed interconnected elastic web 1150 may 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.

Finally, alternatively or additionally, the second resilient module 1130a may also be made to not deform significantly during the first compression process by having the second resilient module 1130a itself have a greater spring rate, such as a stiffer coil spring 1133.

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 alone. Moreover, the first elastic modules 1120 of each elastic assembly 1110 are independent of each other, thus exhibiting distinct independent spring pad elastic characteristics.

In case the deformation of the first elastic module 1120a during the first compression process is not yet sufficient to completely resist the pressure F, the second compression process may be performed after the first compression process. During the second compression process, the entire elastic assembly 1110a continues to be compressed downward by the pressure F, at which time the first elastic module 1120a and the second elastic module 1130a are compressed downward substantially simultaneously. Moreover, 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 the adjacent other elastic assemblies 1110, such that the adjacent second elastic modules 1130 are involved together to oppose the pressure force F. From the perspective of the interconnected elastic web 1150 formed by the interconnected bases 1131, once the second elastic module 1130a is compressed, the compression set of the second elastic module 1130a is transferred directly to the second elastic module 1130 of the adjacent other elastic assembly 1120 via the interconnected elastic web 1150 connected thereto, so that the pressure is borne by the second elastic module 1130 of the adjacent other elastic assembly 1120 receiving the set together with the current elastic assembly 1120 a. In this way, the second compression process may exhibit a higher spring rate than the first compression process. In other words, one would feel that the second compression process of the primary elastic layer 1100 appears to be more "stiff" than the first compression process.

As can be seen from a combination of the first and second compression processes, the main elastic layer 1100 and the elastic pad 1000 having the same have the following elastic characteristics: 1) Exhibiting a distinct two-stage elastic character from "soft" to "hard"; and 2) exhibit distinct independent elastic pad characteristics in the first phase, which is characterized as "soft", i.e., the compression states of the different regions of the elastic pad 1000 are independent and do not affect each other.

Second embodiment:

fig. 17 and 18 show an assembled resilient pad 2000 according to a second embodiment of the present invention. As shown in fig. 17 and 18, the spring pad 2000 is substantially flat and extends in the X-Y plane and has a height or thickness extending in the Z-direction. The elastic pad 2000 may include a main elastic layer 2100 and a first cushion layer 2200 covering the main elastic layer. The primary elastomeric layer 2100 may be made of an elastomeric material and provides a primary source of elasticity for the elastomeric pad 2000. The first cushion layer 2200 may be located above the main elastic layer 2100, closer to the human body than the main elastic layer 1100 in use. The first pad layer 2200 may generally have a substantially continuous and planar surface to provide a more human-contacting surface for the resilient pad 2000. The first cushion layer 2200 may also have a degree of elasticity to provide an additional source of elasticity to the cushion 2000.

The primary elastic layer 2100 may include a plurality of elastic components 2110 arranged in an array along the X-Y plane. The structure of the spring pad 2000 and the spring assembly 2110 can be seen more clearly in the exploded view of fig. 19. As shown in fig. 19, each elastic assembly 2110 in the main elastic layer 2100 may include a first elastic module 2120 and a second elastic module 2130 extending in the height direction Z and capable of being elastically deformed in the height direction Z. The first elastic module 2120 can be inserted downward into and held by a corresponding second elastic module 2130 along the height direction Z. That is, the second elastic module 2130 may be both an elastic module and a holding module for holding the first elastic module 2120. In an assembled state in which the first elastic module 2120 is inserted into the second elastic module 2130, an upper end portion of the first elastic module 2120 is protruded out of a receiving space 2135 (see fig. 20) of the second elastic module 2130 in a height direction Z such that the upper end portion of the first elastic module 2120 is higher than the second elastic module 2130. Meanwhile, in the lateral direction perpendicular to the height direction Z, the second elastic module 2130 circumferentially surrounds and holds the first elastic module 2120 outside the first elastic module 2120. Thus, when the resilient pad 2000, and in particular each of the resilient members 2110 in its primary resilient layer 2100, is subjected to a downward pressure, the pressure is received directly by the first resilient module 2120 and the downward pressure transmitted by the first resilient module 2120 is received indirectly by the second resilient module 2130.

It should be noted that in this assembled state, the first elastic modules 2120 of each elastic assembly 2110 may be independent of each other, while the second elastic modules 2130 of adjacent elastic assemblies 2110 may be connected to each other.

The first elastic module 2120 of each elastic assembly 2110 in the elastic pad 2000 may take a shape and structure similar to those of the first elastic module 1120 in the elastic pad 1000 of the first embodiment, as shown in fig. 13. The assembly process of the spring pad 2000 is also similar to the spring pad 1000 of the first embodiment. The main difference between the elastic pad 2000 and the elastic pad 1000 is the structure of the second elastic module 2130, and in addition, the foregoing description of the elastic pad 1000 basically applies to the elastic pad 2000.

Fig. 20 schematically illustrates a second elastic module 2130 that can be adapted for use in an elastic assembly 2110. As shown in fig. 20, the second elastic module 2130 may include a coil spring 2133 capable of elastic deformation. The coil spring 2133 may serve as an elastic body of the second elastic module 2130 and is hollow. The coil spring 2133 may be mounted and constrained between an annular seat ring 2139 and an end cap 2132. In particular, the coil spring 2133 may abut and be retained by the seat ring 2139 at one end (upper end in fig. 20) thereof and may abut the end cap 2132 at the other end (lower end in fig. 20). On the outside of the coil spring 2133, a plurality of flexible straps 2134 extend between the seat ring 2139 and the end cap 2132. Thus, by predetermining the length of the flexible strap 2134, the distance between the seat ring 2139 and the end cap 1132 may be limited, thereby enabling the coil spring 2134 to be constrained between the seat ring 2139 and the end cap 2132 in a pre-compressed state (not a fully free state). The second elastic module 2130 is formed to be elastically deformed while having a certain rigidity by means of the pre-compressed coil springs 2134. The stiffness of the second elastic module 2130 may facilitate shape retention of the second elastic module 2130 in a resting state and may provide suitable initial stiffness or initial support force when it is compressively deformed. In other embodiments, the coil springs 2133 of the second elastic module 2130 may be packaged and precompressed in a manner similar to the bag springs of the first elastic module 1120 shown in fig. 13, and then the upper ends thereof may be mounted to the seat ring 2139. The second elastic module 1130 may also employ an elastic body of a non-coil spring, such as a sponge, a plate spring, etc., where appropriate.

Returning to fig. 20, the flat base 2131 may surround the coil spring 2134 and be positioned lower than the upper end of the coil spring 2133, or lower than the seat 2139, so as to be located vertically (height Z) between the seat 2139 and the end cap 2132. In other words, the base 2131 may be lower than the upper end of the second elastic module 2130 and between the upper end and the lower end of the second elastic module 2130. Generally, in the height direction Z, the base 2131 may be located between half the height of the coil spring 2133 and the upper end. Base 2131 may be connected via flexible piece 2138 with a seat ring 2139 located at an upper end of coil spring 2134. This allows for 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 may be resilient so as to be elastically deformable for force transfer between the seat ring 2139 and the base 2131 and to be self-returning to an original relative position upon relative movement of the seat ring 2139 and the base 2131. The end cap 2132, flexible strap 2134 and flexible piece 2138 may be made of the same material and may be integrally formed. In other embodiments, the flexible member 2138 may be directly to the upper ends of the base 2131 and the coil spring 2133, respectively, when the seat ring 2139 is omitted.

The base 2131 of the second elastic module 2130 may have a connection 2136 for interconnecting with the base 2131 of the second elastic module 2130 of an adjacent other elastic assembly 2110 during assembly to form an elastic base layer 2140, such as shown in fig. 22. The description of the elastic base layer 2140 may refer to the description of the elastic base layer 1140 in the first embodiment with reference to fig. 4, which is not repeated herein. Similarly to the first embodiment, for convenience of assembly, the bases 2131 of the plurality of second elastic modules 2130 may be integrally formed to form a module including the plurality of second elastic modules. As shown in fig. 20, the connection portions 2136 may include connection portions 2136a and 2136b of a concave-convex structure, the protrusion 2136a may be inserted into a recess 2136b of the base 2131 of the adjacent another second elastic module 2130, and the recess 2136b may receive the protrusion 2136a of the base 2131 of the another second elastic module 2130. These connection portions 2136 may also include "rail-to-chute" type connection portions 2136c and 2136d, the rail 2136c may be inserted into a chute 2136d of the base 2131 of the adjacent another second resilient module 2130, and the chute 2136d may receive the rail 2136c of the base 2131 of the other second resilient module 2130.

As shown in fig. 20, the second resilient module 2130 and its coil springs 2133 may be tapered or truncated cone shaped in a direction from the seat ring 2139 to the end cap 2132, and in an assembled state, may be inverted. The second elastic module 2130 may be hollow and its seat ring 2139 may have an opening 2137 such that the second elastic module 1130 has an upwardly open receiving space 2135. The accommodation space 2135 may be defined by an inner side surface of the coil spring 2133 and an upper surface of the end cap 2132. This allows the first elastic module 2120 to be inserted into the receiving space 2135 of the second elastic module 2130 from above downward, so that the first elastic module 2120 can be held by the second elastic module 2130, resulting in an assembled elastic assembly 2110. The receiving space 2135 may also be an inverted cone or truncated cone tapered in a direction from the seat ring 2139 to the end cap 2132, and thus may be formed to substantially taper fit with the inverted cone or truncated cone shaped first resilient module 2120, such that the second resilient module 2130 more firmly retains the first resilient module 2120. It can be seen that this tapered fit between the first resilient module 2120 and the receiving space 2135 of the second resilient module 2130 is particularly convenient for assembling and disassembling the resilient assembly 2110, which is not described in detail herein with reference to the description of the resilient assembly 1110 of the first embodiment. In other embodiments, other shaped surface fits between the first resilient module 2120 and the receiving space 2135 of the second resilient module 2130 that facilitate assembly and disassembly are also possible. Moreover, the conical or frustoconical shape of the second elastic module 2130 and its upwardly open accommodation space 2135 also allow for a plurality of second elastic modules 2130 to be nested one on top of the other, as shown in fig. 21, which facilitates storage and transportation of the second elastic modules 2130 in a compact volume in the unassembled state. It is noted that, for ease of nesting, the flexible member 2138 may extend obliquely outward and downward from the upper end of the coil spring 2133.

Fig. 23 is a side view of the primary elastic layer 2100 in fig. 17 and 18, and the elastic characteristics of the primary elastic layer 2100 will be described below with reference to fig. 23. As shown in FIG. 23, the primary elastic layer 2100 may include a plurality of elastic members 2110 arrayed in the X-Y plane. In the event that one of the plurality of elastic members 2110a is subjected to a downward pressure F, or the elastic member 2110a is located at a concentrated point of pressure F, the elastic member 2110a will be able to undergo a first compression process and optionally second and third compression processes.

During the first compression process, the first elastic module 2120a in the elastic assembly 2110a first receives the downward pressure F directly and is compressed significantly downward by it, while the second elastic module 2130a is not or not compressed significantly downward. In particular, for the first elastic module 2120a having an inverted conical or truncated conical coil spring, an upper portion thereof has a relatively small elastic coefficient (i.e., relatively soft) due to a large diameter, and a lower portion thereof has a relatively large elastic coefficient (i.e., relatively hard) due to a small diameter. In this way, the upper portion of the first elastic module 2120a is first significantly compressed by the pressure F. During the first compression, although the second elastic module 2130a may receive the pressure transferred from the first elastic module 2120a due to the contact with the first elastic module 2120a, the transferred pressure acts substantially dispersedly on the bottom surface and the tapered side surface of the second elastic module 2130a, and the upper end portion of the second elastic module 2130a does not receive a significantly concentrated downward pressure, and thus the second elastic module 1130 is not significantly compressed.

Furthermore, referring to fig. 22, the second elastic modules 2130 of each elastic assembly 2110 form an elastic base layer 2140 by interconnecting at the base 2131, which allows for the influence of the interaction rather than independence between each second elastic module 2130. Thus, in the case where 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 plurality of second elastic modules 2130 of the surrounding area via the flexible member 2138 and the base 2131 and bears the pressure together therewith. This also allows the second elastic module 2130a to not deform significantly during the first compression process.

Finally, alternatively or additionally, the second elastic module 2130a may also be made to not deform significantly during the first compression process by having the second elastic module 2130a itself have a greater spring coefficient, such as a stiffer coil spring 2133.

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 assembly 2110 alone. Moreover, the first spring modules 2120 of each spring assembly 2110 are independent of each other, thus exhibiting distinct independent spring pad spring characteristics.

In case the deformation of the first elastic module 2120a during the first compression is not yet sufficient to completely resist 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 continues to compress downwardly by the pressure F, at which point the first elastic module 2120a and the second elastic module 2130a are compressed downwardly substantially simultaneously.

The upper end of the second elastic module 2130a or its seat ring 2139 is connected to the base 2131 via a flexible piece 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 may be substantially absorbed by the flexible member 2138 and not substantially transferred to the second elastic module 2130 of the adjacent other elastic assembly 2110. That is, during the second compression process, the compressive force F is primarily resisted by the deformation of the first and second elastic modules 2120a, 2130a, and the interconnecting elastic web 2150 and other adjacent elastic components 2110 do not participate significantly. The main elastic layer 2110 of the second embodiment may exhibit a higher elastic coefficient during the second compression process than during the first compression process. In other words, one would feel that the second compression process of the primary elastic layer 2100 appears to be more "stiff" than the first compression process.

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

During the third compression, as the flexible member 2138 fails to continue to absorb the deformation of the second elastic module 2130a, or as 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 significantly withstand the pressure F and transfer the deformation of the second elastic module 2130a directly to the second elastic module 2130 of the adjacent other elastic assembly 2110 such that the adjacent second elastic module 2130 will be involved together to oppose the pressure F. From the perspective of the interconnected elastic web 2150 formed by the interconnected bases 2131, when the bases 2131 begin to significantly withstand the pressure F, i.e., the interconnected elastic web 2150 begins to significantly withstand the pressure F. At this point, the interconnected elastomeric web 2150 will be substantially involved in the compression process and will transmit the pressure F to the second elastomeric module 2130 of the adjacent other elastomeric assembly 2120 so that the pressure is borne by the second elastomeric module 2130 of the adjacent other elastomeric assembly 2120 along with the current elastomeric assembly 2120 a. In this way, the third compression process may exhibit a higher spring rate than the second compression process. In other words, one would feel that the third compression process of the primary elastic layer 2100 appears to be more "stiff" than the second compression process.

Referring to fig. 23, it should be noted that the interconnected bases 2131 of the respective second elastic modules 2130 may actually form an interconnected elastic web (as enclosed by the dashed box 2150) extending in the X-Y plane. The interconnected elastic web 2150 is used to interconnect or link the second elastic modules 2130 of each elastic component 2110 in the primary elastic layer 2100 to transfer pressure and/or elastic deformation between the interconnected second elastic modules 2130 to form the aforementioned interaction. Thus, when the elastic component 2110a is compressed to such an extent that its second elastic module 2130a begins to elastically deform, pressure can be transferred via the interconnected elastic web 2150 to the adjacent other elastic component 2110 (particularly the adjacent elastic component) so that the other elastic components 2110 (particularly the second elastic module 2130) can bear together against the pressure. In the present embodiment, since the base 2131 is located at the upper end of the second elastic module 2130 or the coil spring 2133, the base 2131 is located between the upper end and the lower end thereof with respect to the assembled elastic assembly 2110, which also allows the internet elastic web 2150 to be located between the upper surface and the lower surface 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 primary elastic layer 2100 may be interconnected, such that the interconnected elastic web 2150 formed may transfer pressure and/or elastic deformation only between the interconnected second elastic modules 2130, thereby contributing different elastic properties to the primary elastic layer 2100.

As can be seen from the combination of the first to third compression processes, the main elastic layer 2100 and the elastic pad 2000 having the same have the following elastic characteristics: 1) Exhibits a distinct three-stage elastic characteristic from "soft" to "hard" to "harder", unlike the two-stage elastic characteristic of the elastic pad 1000; and 2) exhibit distinct independent resilient pad characteristics in both the first and second phases, i.e., the compression states of the different regions of the resilient pad 2000 are independent and do not affect each other.

In the foregoing description, the base 2131 is lower than the upper end of the second elastic module 2130 and is between the upper end and the lower end 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 is formed as an upper end portion of the entire second elastic module 2130 and is positioned between upper and lower end portions of the entire elastic assembly 2100. Thus, after only the first elastic module 2120 is compressed, the interconnected elastic web 2150 of interconnected bases 2131 participates in opposing the pressure F by involving adjacent other elastic components 2110 before the first and second elastic modules 2120, 2130 are synchronously compressed. That is, the interconnecting elastic web 2150 will participate earlier than in the situation shown in fig. 23, so that the elastic pad and the primary elastic layer exhibit different elastic characteristics than the second embodiment.

In yet another embodiment, not shown, the position of the base 2131 in the second elastic module 2130 may be further lowered such that the base 2131 is at the lower end of the second elastic module 2130 and such that the base 2131 is also at the lower end of the entire elastic assembly 2110. In this way, the interconnection structure formed by the interconnected bases 2131 will not participate in any compression process, such that the elastic pad and the primary elastic layer exhibit different elastic characteristics than the second embodiment.

Third embodiment:

fig. 24 and 25 show an assembled resilient pad 3000 according to a third embodiment of the present invention. As shown in fig. 24 and 25, the elastic pad 3000 is substantially flat and extends in the X-Y 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 provides a primary source of elasticity for the elastic pad 3000. The first cushion layer 3200 may be positioned above the main elastic layer 3100, closer to the human body than the main elastic layer 3100 in use. The first cushion layer 3200 may generally have a substantially continuous and planar surface to provide a surface of the resilient cushion 3000 that is more suitable for human contact. The first cushion layer 3200 may also have a degree of elasticity to provide an auxiliary source of elasticity for the resilient cushion 3000.

It should be noted that although first cushion layer 3200 is generally planar in overall, this does not preclude that the upper surface of first cushion layer 3200 may have concave and/or convex structures 3220 that do not interfere with human contact comfort, and preferably are resilient.

The primary elastic layer 3100 can include a plurality of elastic members 3110 arranged in an array along an X-Y plane. The structure of the resilient pad 3000 and the resilient assembly 3110 can be seen more clearly in the exploded view of fig. 26. As shown in fig. 26, each elastic assembly 3110 in the main elastic layer 3100 may include a first elastic module 3120 and a second elastic module 3130 extending in the height direction Z and capable of being elastically deformed in the height direction Z. The first elastic modules 3120 can be inserted downward into and held by the corresponding second elastic modules 3130 along the height direction Z. That is, the second elastic module 3130 may be both an elastic module and a holding module for holding the first elastic module 3120. In an assembled state in which the first elastic module 3120 is inserted into the second elastic module 3130, an upper end portion of the first elastic module 3120 is protruded out of the accommodation space 3135 (see fig. 27) of the second elastic module 3130 in the height direction Z such that the upper end portion of the first elastic module 3120 is higher than the second elastic module 3130. Meanwhile, in the lateral direction perpendicular to the height direction Z, the second elastic module 3130 may circumferentially surround and hold the first elastic module 3120 at the outside of the first elastic module 3120. Thus, when the resilient pad 3000, and in particular each resilient element 3110 in its main resilient layer 3100, is subjected to a downward pressure, the pressure is received directly by the first resilient module 3120 and the downward pressure transmitted by the first resilient module 3120 is received indirectly by the second resilient module 3130.

It should be noted that, in the assembled state, the first elastic modules 3120 of each elastic assembly 3110 may be independent from each other, and the second elastic modules 3130 of adjacent elastic assemblies 3110 may be connected to each other.

The first elastic module 3120 of each elastic assembly 3110 in the elastic pad 3000 may take 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, as shown in fig. 13. The assembly process of the elastic pad 3000 is also similar to the elastic pads 1000 and 2000 of the first and second embodiments. The main difference between the resilient pad 3000 and the resilient pads 1000 and 2000 is the structure of the second resilient module 3130, and in addition, the foregoing description of the resilient pads 1000 and 2000 also applies substantially to the resilient pad 3000.

Fig. 27 and 28 schematically illustrate a second spring module 3130 that can be adapted for use with the spring assembly 3110. As shown in fig. 27 and 28, the second elastic module 3130 may include a coil spring 3133 capable of elastic deformation. The coil spring 3133 may serve as an elastic body of the second elastic module 3130, and is hollow. The coil spring 3133 may be installed and restrained between the installation cylinder 3132 and the flat base 3131 in the height direction Z. A base 3131 may be located at a lower end of the elastic member 3110. The mounting cylinder 3132 may be made of a non-deformable, non-elastic material and may have a flange 3139 at its upper end extending laterally outward. 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 portion to support the mounting cylinder, and may abut against the base 3132 at the lower end portion. The mounting cylinder 3132 extends downward from its flange 3139 on the inside of the coil spring 3133 so as to extend substantially inside the coil spring 3133. Downward or upward movement of the mounting cylinder 3132 can compress or release the coil spring 3133, respectively. In other embodiments, the mounting cylinder 3132 may be connected to the upper end of the coil spring 3133 in other suitable manners.

In order to firmly hold the coil spring 3133, the base 3131 may have an annular groove 3131a so that a lower end portion of the coil spring 3133 may be detachably fitted into the annular groove 3131 a. On the outside of the coil spring 3133, a plurality of flexible straps 3134 extend between the mounting cylinder 3132 and the base 3131. In this way, by determining the length of the flexible band 3134 in advance, the distance between the mounting cylinder 3132 and the base 3131 can be limited, thereby enabling the coil spring 3134 to be restrained between the mounting cylinder 3132 and the base 3131 in a pre-compressed state (not a fully free state). The second elastic module 3130 is formed to be elastically deformed while having a certain rigidity by means of the pre-compressed coil spring 3134. The stiffness of the second elastic module 3130 may facilitate shape retention of the second elastic module 3130 in a stationary state, and may provide a suitable initial stiffness or initial supporting force when it is compressively deformed. The flexible strap 3134 and the mounting cylinder 3132 may be made of the same material and integrally formed.

The base 3131 of the second elastic module 3130 may have a connection portion 3136 for interconnecting with the base 3131 of the second elastic module 3130 of the adjacent other elastic assembly 3110 during assembly to form an elastic base layer 3140 as shown, for example, in fig. 30. The elastic base layer 3140 may be described with reference to fig. 4 and the elastic base layer 1140 in the first embodiment, which will not be described herein. Similarly to the first embodiment, for convenience of assembly, the bases 2131 of the plurality of second elastic modules 2130 may be integrally formed to form a module including the plurality of second elastic modules. As shown in fig. 27, these connecting portions 3136 may include "rail-to-chute" type connecting portions 3136c and 3136d, the rail 3136c may be inserted into a chute 3136d of the base 2131 of the adjacent another second elastic module 3130, and the chute 3136d may receive the rail 3136c of the base 3131 of the another second elastic module 3130.

As shown in fig. 27, the coil spring 3133 of the second elastic module 3130 may be a cone or truncated cone tapered from the upper end to the lower end in the vertical direction or the height direction Z, and in the assembled state, may be a positive one, unlike the inverted cone or truncated cone coil springs 1133 and 2133 of the first and second embodiments. In this case, the receiving space 3135 required to receive the first elastic module 3120 of an inverted cone shape or a truncated cone shape may be provided by the mounting cylinder 3132. The mounting cylinder 3132 may be hollow, and an upper end portion thereof may have an opening 3137U such that a mounting space 3135 of the mounting cylinder 3132 is upwardly opened. In this way, the first elastic module 3120 is allowed to be inserted into the accommodating space 3135 of the second elastic module 3130 from the upper direction, so that the first elastic module 3120 can be held by the second elastic module 3130, forming an assembled elastic assembly 3110. The receiving space 3135 defined by the inner side surface of the hollow mounting cylinder 3132 may also be an inverted cone or truncated cone tapered from the upper end portion to the lower end portion in the assembled state, and thus may be formed substantially in conical surface engagement with the first elastic module 3120 which is inverted cone or truncated cone in the assembled state, so that the second elastic module 3130 more firmly holds the first elastic module 3120. The mounting cylinder 3132 can firmly hold the first elastic module 3120 only with such surface engagement with the first elastic module 3130 without other connection and fixing operations.

It can be seen that this tapered 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, which is described above with reference to the elastic assembly 1110 of the first embodiment, and will not be repeated here. In other embodiments, other shaped surface fits between the first resilient module 3120 and the receiving space 3135 of the second resilient module 3130 that facilitate assembly and disassembly are also possible.

The second elastic module 3130 exhibits a substantially M-shaped cross-sectional shape as a whole. The coil spring 3122 of the second elastic module 3130 forms an outer profile of a substantially right-hand cone or truncated cone shape, and the mounting cylinder 3132 forms an inner profile of an inverted cone or truncated cone shape, which is more clearly seen in the sectional view shown in fig. 27. Further, the base 3131 of the second elastic module 3130 may have an opening 3131b, and the opening 3131b may have a size larger than that of the upper end of the second elastic module 3130, for example, 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 the lower end thereof has an opening 3131b, this allows another second elastic module 3130 to be inserted into the current second elastic module 3130 via the opening 3131b, so that a plurality of second elastic modules 3130 can be stacked on each other in a non-assembled state, as shown in fig. 29, which facilitates storage and transportation of the second elastic modules 3130 in a compact volume in the non-assembled state.

Referring to fig. 28, a dotted line D in the drawing indicates a plane in which the bottom surface of the second elastic module 3130 is located at the lowest position of the second elastic module 3130. It will be appreciated that the plane shown by the dashed line D is also the plane in which the bottom surface of the elastic assembly 3110 and the bottom surface of the main elastic layer 3100 sit, as shown in fig. 25 and 37. Returning to fig. 28, it can be seen that the vertical position of the lower end of the mounting cylinder 3132 can be significantly higher than the bottom surface of the second elastic module 3130. In this way, when the mounting cylinder 3132 receives a downward pressure, it can be moved downward by compressing the coil spring 3133. The mounting cylinder 3132 may also have an opening 3137L at its lower end portion. Thus, as shown in fig. 31, when the first elastic module 3120 is inserted into the second elastic module 3130 to form the elastic assembly 3110, the lower end portion of the first elastic module 3120 may first pass through the upper opening 3137U of the mounting cylinder 3132 and then pass through the lower opening 3137L of the mounting cylinder 3132 until the first elastic module 3120 is stably held by the mounting cylinder 3132. By predetermining the taper of the first spring module 3120 and the mounting cylinder 3132 and the length of the first spring module 3120, the lower end of the first spring module 3120 may be higher than or suspended above the bottom surface of the second spring module 3130 or the spring assembly 3110 as shown by the dashed line D in the assembled state.

Thus, referring to fig. 31, when the elastic assembly 3110 is subjected to a downward pressure F, the pressure F is first directly received by the first elastic module 3120 and is significantly compressed downward. During the compression of the first elastic module 3120, the pressure is rapidly transmitted to the tapered side of the mounting cylinder 3132 due to the contact with the mounting cylinder 3132 of the second elastic module 3130. Since the mounting cylinder 3132 and the lower end portion of the first elastic module 3120 are suspended, the pressure applied to the tapered side surface of the mounting cylinder 3132 is concentrated at the flange 3139 thereof to the upper end portion of the coil spring 3133, so that the second elastic module 3130 is also subjected to a significant downward pressure and opposes the pressure F together with the first elastic module 3120. In other words, with the elastic assembly 3110 of the present embodiment, the first elastic module 3120 and the second elastic module 3130 basically work together to resist the pressure F at the beginning. This differs from the elastic assemblies 1110 and 2110 of the first and second embodiments in that the pressure F is primarily opposed by the first elastic modules 1120 and 2120 during the first compression thereof, and the second elastic modules 1130 and 2130 do not participate significantly.

Since the coil spring 3133 of the second elastic module 3130 has a normal conical or truncated conical shape, and the coil spring (not shown) of the first elastic module 3130 has an inverted conical or truncated conical shape and works together when the elastic member 3110 is subjected to the downward pressure F, the overall elastic performance of the elastic member 3110 is similar to that of the concave coil spring shown in fig. 32. The elastomeric assembly 3110 of this embodiment initially exhibits a softer elastomeric character than the first and second embodiments, which operate primarily during the first compression by the inverted cone coil spring 1124 shown in fig. 13.

Further, in this third embodiment, the base 3131 of the second elastic module 3130 is located at the bottom surface (broken line D) of the entire elastic assembly 3110. Therefore, the connection point of the adjacent second elastic module 3130 is also at the bottom surface of the elastic assembly 3110. In this way, no additional spring assemblies 3110 are involved in the overall compression of the spring assemblies 3110, thereby exhibiting better spring characteristics of the individual spring pads than the spring assemblies 1110 and 2110 of the first and second embodiments.

The elastic assembly 3110 may be combined by two independent conical coil springs of the first and second elastic modules 3120 and 3130, as compared to an integral concave coil spring. In this way, a greater variety of different elastic properties can be combined by adjusting the elastic characteristics of the two coil springs separately. Moreover, the first and second elastic modules 3120 and 3130 each have a tapered shape to facilitate storage of the stacks, respectively. Finally, the assembly of the first and second elastic modules 3120 and 3130 is simple, and only the first elastic module 3120 needs to be inserted into the second elastic module 3130 from above.

Other embodiments:

fig. 33 schematically illustrates another embodiment of a resilient assembly 4110. As shown in fig. 33, the elastic member 4110 may include a first elastic module 4120 and a second elastic module 4130 capable of being elastically deformed in the height direction Z of the elastic pad, similar to the elastic members 1110, 2110 and 3110 in the first to third embodiments. The upper end of the first elastic module may be higher than the second elastic module in the height direction Z. Meanwhile, in the lateral direction perpendicular to the height direction Z, the second elastic module 4130 may surround the first elastic module 4130 along the circumference thereof outside the first elastic module 4120. That is, the tall first resilient module 4120 is an inner resilient module and the short second resilient module 4130 is an outer resilient module.

Unlike the elastic members 1110, 2110 and 3110 of the first to third embodiments, the first and second elastic modules 4130 and 4130 of the elastic member 4110 may not have a fitting relationship held by one another. In this way, when the resilient assembly 4110 is subjected to downward pressure, the pressure is first received directly by the first resilient module 4120, but the first resilient module 4120 does not significantly transfer the pressure to the second resilient module 4130. Accordingly, during the first compression process, the first elastic module 4120 is significantly compressed downward, and the second elastic module 4130 is not compressed downward. In other words, during the first compression, the deformation of the elastic member 4110 in the height direction Z is entirely provided by the deformation of the first elastic module. The second compression process will begin until the first resilient module 4120 is significantly compressed a distance, such as when its upper end is substantially flush with the upper end of the second resilient module 4130. During the second compression process, the second elastic module 4130 may directly receive the pressure together with the first elastic module 4120 and be simultaneously compressed downward. In other words, during the second compression, the deformation of the elastic member 4110 in the height direction Z is provided by the deformation of the first and second elastic modules 4120 and 4130 together.

It should be noted that the first and second elastic modules 4120 and 4130 cooperate to oppose the pressure in the second compression process, as opposed to merely the first elastic module 4120. Thus, the resilient member 4110 as a whole exhibits a greater spring rate during the second compression than during the first compression, and one would feel that the resilient member 4110 and the resilient pad formed therefrom exhibit a more "stiff" during the second compression. Thus, the resilient member 4110 may also provide a two-stage resilient feature from "soft" to "hard".

Fig. 34 schematically illustrates another embodiment of an elastic assembly 5110. The difference from the elastic assembly 4110 is that in the elastic assembly 5110, the tall first elastic module 5120 is an outer elastic module and the short second elastic module 5130 is an inner elastic module. The compression process and spring characteristics of spring assembly 5110 are similar to spring assembly 4110.

Each of the elastic modules 4110 and 5110 shown in fig. 33 and 34 may be a coil spring having an equal diameter in the height direction Z, or may be a bag-type spring pack formed by wrapping a flexible material around the coil spring. In assembly, the outer resilient modules 4130, 5120 are simply sleeved outside the inner resilient modules 4120, 5130. Although not shown, the resilient members 4110, 5110 may also have bases to interconnect adjacent resilient members when the primary resilient layer is assembled. A plurality of elastic members 4110, 5110 are arranged in an array along the X-Y plane, and may constitute the main elastic layer of the elastic pad. The first cushion layer of the first to third embodiments is laid on top of the main elastic layer, and then the desired elastic cushion can be assembled.

In the elastic assembly of the first to third embodiments, the first elastic module is tapered or truncated cone shaped as a whole, and the accommodation space for holding the first elastic module is also tapered or truncated cone shaped as a whole. In other embodiments, the receiving space and the first elastic module may not be tapered as a whole, but have tapered portions, respectively. The corresponding taper of the first elastic module is held by the taper of the receiving space of the second elastic module and is formed substantially as a taper fit. The tapering is formed only locally, which may be detrimental for compact storage and transport of the first and second elastic modules in a nested manner, but is still possible when manufacturing and selling integrated elastic mats.

In one embodiment, the elastic assembly may include a first elastic module extending in a height direction of the elastic pad and a holding module for holding the first elastic module. The holding module may be formed with an upwardly open receiving space to allow the first elastic module to be inserted into the receiving space from above downward and thereby hold the first elastic module. In a state in which the first elastic module has been inserted into and held by the accommodation space of the holding module, an upper end portion of the first elastic module may extend upward out of the accommodation space and be higher than the holding module so that when the elastic assembly is subjected to downward pressure, the pressure is first received by the first elastic module. The first elastic module may be selected from one of the first elastic modules described in the above embodiments. The holding module may be elastic and may be selected from one of the second elastic modules described in the above embodiments, which is capable of being elastically deformed in the height direction of the elastic pad, and thus the elastic assembly is formed as described in the first to third embodiments.

The retention module may also be inelastic. For example, the holding module may have a feature (e.g., accommodation space, etc.) of the holding function of the second elastic module, while the elastic feature (e.g., coil spring, etc.) of the second elastic module may be omitted. In some embodiments, the holding module may be in the form of a holding seat formed of a non-deformable material and having a receiving space for holding the first elastic module as described previously. Such a holding module is a substantially rigid module which is substantially free from deformations in the height direction Z. It will be appreciated that the resilient assembly formed with such a retention module also has the advantage of facilitating assembly and disassembly of the resilient assembly described in the first and third embodiments, i.e. assembly and disassembly of the resilient assembly can be achieved with a simple single insertion or withdrawal action.

To illustrate the elastic assembly 3110 shown in fig. 31 as an example, in order to enable the holding module (here, the second elastic module 3130) to firmly hold the first elastic module 3120, in the assembled state, the height H1 of the portion of the first elastic module 3120 above the upper end of the holding module 3130 preferably does not exceed 80% of the total height H2 of the first elastic module 3120. Typically, H1 may be between 30% and 70% of H2. The same applies to the elastic assembly in the first and second embodiments, as well as to elastic assemblies comprising other types of retention modules.

In one embodiment, the elastic pad may include a primary elastic layer that may include a plurality of elastic components and an interconnected elastic web. Each elastic assembly may include first and second elastic modules. The elastic pad may be the elastic pad 1000, 2000 of the first and second embodiments, wherein the interconnected elastic web may be formed of interconnected bases 1131, 2131, such as the interconnected elastic webs 1150, 2150 shown in fig. 16 and 27. In other embodiments, the interconnected elastic web may be other structures unrelated to the base. For example, the base 2131 and the flexible pieces 2138 in the second elastic module 2130 shown in fig. 20 may be omitted and the seat rings 2139 of adjacent second elastic modules may be connected to each other with a connector at the time of assembly, thereby forming the internet. For another example, with respect to the elastic members 4110 shown in fig. 33, when a plurality of such elastic members 4110 are densely arranged in an array, a main elastic layer 4100 may be formed as shown in fig. 35. It is to be appreciated that for clarity of illustration, fig. 35 shows only a small number of resilient assemblies 4110. The second elastic modules 4130 of the elastic members 4110 adjacent to each other in the direction parallel to the paper surface and perpendicular to the paper surface may be bonded together at partial positions on the bottom surface of the main elastic layer 4100 by bonding, welding or the like, and the bonding positions are schematically indicated by black dots. Such attachment may also form the desired interconnected elastic web 4150.

In one embodiment, an elastic pad may include a flat base layer and a plurality of first elastic modules in an extended plane thereof. The base layer may have an upper surface and a lower surface opposite the upper surface. The base layer may have a plurality of retaining pockets distributed in an array at an upper surface thereof, each retaining pocket being recessed downwardly from the upper surface of the base layer. Each of the first elastic modules may extend in a height direction of the elastic pad and be elastically deformable in the height direction. The lower end of each first elastic module may be inserted into one of the recesses of the base layer so as to be held by the base layer. The upper end of each first elastic module may extend upward and beyond the upper surface of the base layer. The base layer may be elastic in the height direction Z, and such base layers 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 being interconnected in an extension plane X-Y, and the accommodation spaces therein form holding pockets in the present embodiment. For example, referring to fig. 4, the receiving space 1135 of the second resilient module 1130 is also a retaining pocket 1143 of the resilient base layer 1140. The specific structure of the second elastic module may be referred to the previous description, and will not be described herein. It is to be understood that the second elastic body of the second elastic modules 1130, 2130, 3130 constituting the elastic base layer 1140, 2140, 3140 may be helical springs 1133, 2133, 3133 extending in the height direction, which makes the elastic base layer 1140, 2140, 3140 in fact a spring net having a certain thickness. In other embodiments, the base layer may take other suitable forms of spring mesh.

In another embodiment, the base layer may also be integrally formed from other resilient materials, such as sponge, silicone, rubber, etc., as shown in fig. 36-39. The base layer 6140 is shown in fig. 36, the base layer 6140 having a flat body 6144 made of an elastic material such as sponge, an upper surface 6141, and a lower surface 6142 opposite the upper surface 6141. The base layer 6140 may also have a plurality of retaining pockets 6143 distributed in an array at its upper surface 6141, each retaining pocket 6143 recessed from the upper surface 6141 of the base layer 6140 toward the interior of the body 6144, i.e., recessed downward toward the lower surface 6142. The retaining pockets 6143 may be in the shape of an inverted cone or truncated cone, i.e., with a transverse dimension that tapers in a direction from the upper surface 6141 to the lower surface 6142, as seen more clearly in the cross-sectional view of fig. 37. Such a tapered or truncated cone shape of the retaining pockets 6143 is particularly suited for retaining the inverted tapered or truncated cone first resilient module 6120, as shown in fig. 38. Each of the first elastic modules 6120 may extend in the height direction Z of the elastic pad, and be elastically deformable in the height direction Z. Each first elastic module 6120 corresponds to one holding pocket 6143, and a lower end portion of the first elastic module 6120 may be inserted into the corresponding holding pocket 6143 in the base layer 6140 so as to be held by the base layer 6140. As shown in fig. 39, in a state in which the first elastic module 6120 has been inserted into the holding pocket 6143, an upper end portion of the first elastic module 6120 may extend upward outside the holding pocket 6143, that is, beyond the upper surface 6143 of the base layer 6140. The first cushion layer 6200 is laid over the array of first elastic modules 6120 to form an elastic cushion 6000. The first elastic module 6120 may employ first elastic modules similar to the previous embodiments, such as the first elastic modules 1120, 2120, and 3120, which will not be described in detail herein. In other embodiments, the base layer 6140 may also be inelastic, thereby not contributing elasticity to the elastic pad 6000, but rather merely serving to retain the first elastic module 6120. In this case, the body 6144 of the base layer 6140 may be made of a suitable inelastic material.

As shown in fig. 40, the elastic pad of each of the above embodiments is disposed on the supporting frame after wrapping the outer cover, so as to form a bed. In other embodiments, the resilient pad of each of the foregoing embodiments may also be used as a bed directly on the ground, where appropriate. In other embodiments, the resilient pads of the foregoing embodiments may be disposed onto a sofa frame to form a desired sofa.

The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
