Description

[Technical Field]

[0001] The present invention relates to the field of furniture, and in particular to resilient padding, additional resilient padding layers and furniture. [Background technology]

[0002] As people's material wealth continues to increase, the demand for interior goods is also gradually changing. In particular, the needs of users for products that are used for long periods of time, such as bed pads and sofa pads, are becoming more diverse and diverse.

[0003] Incidentally, in the current marketing of interior products, bed pads are clearly divided into high-end and low-end. Low-end bed pads are generally thin and easy to transport and store, but they do not fully satisfy the user's need for comfort. On the other hand, high-end bed pads generally have complex internal structures, exquisite finishes, and are relatively thick, providing excellent comfort when users sit or lie on them. However, due to their complex internal structures, high-end bed pads are often non-removable, and the only forms available to users are one-piece non-removable bed pads, which causes inconvenience when transporting and storing the bed pads. Furthermore, when some of the components of high-end products deteriorate, users are unable to perform purposeful maintenance and must simply discard the entire pad, resulting in waste.

[0004] Furthermore, current high-end mattress pads are all one-piece structures, and users cannot adjust the softness or hardness of the mattress pads. To obtain different experiences, users must purchase multiple high-end mattress pads. Currently, there are no high-end mattress pads that users can customize.

[0005] Furthermore, even if there are proposals for high-quality bed pads that can be detached and customized, it is still worth researching how to simplify the customization process and make the operation more convenient.

[0006] Therefore, there is a need to provide resilient pads, additional resilient padding layers, and furniture that address at least some of the above problems. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0037] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described here are only preferred embodiments of the present invention, and other forms that can realize the present invention that can be conceived by those skilled in the art based on the preferred embodiments also fall within the scope of the present invention.

[0038] The present invention provides an elastic pad for use in interior products and furniture including the elastic pad, such as a bed pad, sofa pad, or other pad for users to sit or lie on. The elastic pad allows users to customize, assemble, remove, and store the pad themselves. Figures 1 to 27 show some preferred embodiments of the present invention.

[0039] It should be explained from the outset that the directional and positional terms described in the present invention should be understood with reference to the embodiments shown in Figures 1 to 27. The directional and positional terms described in the present invention all indicate relative directions and relative positions between components, and do not indicate absolute directions or absolute positions.

[0040] First, referring to FIG. 1, the elastic pad in one preferred embodiment of the present invention has a rectangular parallelepiped structure, and the terms "vertical direction," "lateral direction," and "height direction" described below should be understood with reference to the rectangular parallelepiped structure shown in FIG. 1. For example, in each preferred embodiment of the present invention, the track rails extend in the horizontal direction and are arranged at intervals in the vertical direction. The "left and right sides" of a component refer to both sides of the component in the horizontal direction. Furthermore, although the present invention further describes the "circumferential direction," this does not necessarily apply only to circular structures. In the structure shown in FIG. 1, the circumferential direction also refers to the direction in which a plane defined by the horizontal and vertical directions surrounds the four periphery of the elastic pad 100.

[0041] Referring to FIG. 1, an elastic pad 100 includes an elastic pad main body 101 and at least one additional elastic pad layer 102. The at least one additional elastic pad layer 102 is independent of each other and is also independent of the elastic pad main body 101, and the at least one additional elastic pad layer 102 may be attached to the top outer surface of the entire elastic pad main body 101 in a stacked manner. Although three additional elastic pad layers 102 are schematically shown in FIG. 1, the example is not limited to the example shown in FIG. 1, and a user may select the required type and / or number of additional elastic pad layers 102 according to their needs. An exemplary explanation of the term "user's needs" will be provided below.

[0042] 2 to 6 show the attachment form between the additional elastic pad layer 102 and the elastic pad body 101 in this embodiment. Generally speaking, a first connecting structure is fixedly installed on each side of each of the additional elastic pad layers 102, and a second connecting structure is fixedly installed correspondingly on the elastic pad body 101, and the second connecting structure is configured to be connectable to the first connecting structure of the additional elastic pad layer 102 stacked on top of the elastic pad body 101.

[0043] 4 and 5, in this embodiment, a snap ring 1021a is provided on the side of the first additional elastic pad layer 1021 as a first connecting structure, a snap ring 1022a is provided on the side of the second additional elastic pad layer 1022 as a first connecting structure, and a snap ring 1023a is provided on the side of the third additional elastic pad layer 1023 as a first connecting structure. The snap rings of the first additional elastic pad layer 1021, the second additional elastic pad layer 1022, and the third additional elastic pad layer 1023 are aligned in the height direction of the elastic pads. At the same time, only one second connecting structure 1015 is provided on the elastic pad body 101, and the one second connecting structure 1015 is configured to be connectable to the first connecting structures of all the additional elastic pad layers 102. The second joining structure 1015 includes a webbing 1015a and an engaging upper member 1015b and an engaging lower member 1015c located on both ends of the webbing 1015a, and the first joining structure and the second joining structure are configured so that the webbing can be fastened by the engaging upper member 1015b and the engaging lower member 1015c after it has passed through all of the snap rings of the additional elastic pad layer 102.

[0044] In other embodiments not shown, the first and second connecting structures are zippers, Velcro, or push buttons. For example, the first connecting structures may be structures such as multiple magnets, push buttons, or Velcro that are aligned in the height direction, and the second connecting structures may be structures that can be connected to only one but all of the first connecting structures at the same time.

[0045] 10A to 10C, some exemplary additional elastic pad layers will be described in detail. In Fig. 10A to 10C, the additional elastic pad layers include a first additional elastic pad 1021, a second additional elastic pad 1022, and a third additional elastic pad 1023, which are independent of each other. The third additional elastic pad layer 1023 has a higher hardness than the second additional elastic pad layer 1022, and the second additional elastic pad layer 1022 has a higher hardness than the first additional elastic pad layer 1021.

[0046] In the combination of additional elastic pad layers shown in FIG. 10A, the first additional elastic pad layer 1021 is closest to the user, the third additional elastic pad layer 1023 is farthest from the user, and the second additional elastic pad layer 1022 is sandwiched between the first additional elastic pad layer 1021 and the second additional elastic pad layer 1022.

[0047] In the combination of additional elastic pad layers shown in Figure 10B, the second additional elastic pad layer 1022 is closest to the user, the first additional elastic pad layer 1021 is furthest from the user, and the third additional elastic pad layer 1023 is sandwiched between the first additional elastic pad layer 1021 and the second additional elastic pad layer 1022. The first additional elastic pad layer 1021 and the second additional elastic pad layer 1022 in Figure 10B may be swapped in position.

[0048] In the combination of additional elastic pad layers shown in FIG. 10C, the third additional elastic pad layer 1023 is closest to the user, the first additional elastic pad layer 1021 is farthest from the user, and the second additional elastic pad layer 1022 is sandwiched between the first additional elastic pad layer 1021 and the second additional elastic pad layer 1022.

[0049] Alternatively, in other embodiments, the first additional elastic pad layer may be positioned in the middle, and the second and third additional elastic pad layers may be positioned on the top and bottom sides of the first additional elastic pad layer, respectively. In the embodiments shown in Figures 10A to 10C and various other combinations of additional elastic pad layers, each additional elastic pad layer can be selected from the following set of additional elastic pad layers. The set of additional elastic pad layers includes an additional elastic pad layer made of eiderdown, an additional elastic pad layer made of goose down, an additional elastic pad layer made of memory sponge, an additional elastic pad layer made of regular sponge, an additional elastic pad layer made of latex, and an additional elastic pad layer made of coconut fiber. Users can then select the type, number, and stacking arrangement of the additional elastic pad layers they need based on their needs. The user's needs include softness needs (for example, some users tend to place an additional elastic padding layer made of a relatively hard coconut fiber closer to the user), tactile needs (users generally tend to place an additional elastic padding layer made of a skin-friendly material such as cashmere closer to the user, and an additional elastic padding layer made of elastic latex closer to the user), auditory needs (it can be understood that some materials produce low noise when compressed. Users tend to place such materials farther from the user), olfactory needs (some users like natural scents such as cashmere and goose down, and these users tend to place them closer to the user), and allergy needs (users tend to place an additional elastic padding layer made of a material that may cause an allergy farther from the user). Thus, in the present invention, the "user's needs" have been fully described in detail.

[0050] In this embodiment, various preferred configurations are also provided for the elastic pad body. Referring to Figures 1, 3, 7A, and 7B, the elastic pad body includes an outer cover 1011, an elastic module layer, and an elastic balance net layer 104. The outer cover 1011 defines a closed storage space, and the outer cover further includes a top cover 1012, a bottom cover 1013, and side enclosures 1011, with a fastener 1014 installed between the side enclosures 1011 and the bottom cover 1013. The elastic module layer is installed in the storage space, and includes a number of elastic modules 106 arranged in an array. Each elastic module 106 is installed with a cone-shaped spring that is compressed along the height direction of the elastic pad. Further, referring to FIG. 11, the elastic balance net layer 104 has a number of openings, the dimensions of which correspond to the outer diameter of the elastic modules 106 at a predetermined height, so that the elastic balance net layer 104 can associate all of the elastic modules 106 by respectively installing the elastic modules 106 within the openings.

[0051] In addition, the phrase "the additional elastic pad layer can be stacked and attached to the entire top outer surface of the elastic pad body" in the present invention means that the additional elastic pad layer 102 is necessarily located above the top cover 1012. Compared to a technical configuration in which the additional elastic pad layer is installed inside the outer cover, this installation makes it easier for users to assemble and replace the additional elastic pad layer. In the present invention, users do not need to frequently remove the elastic pad body, and the cover for the elastic pad body can be made of a material that is resistant to abrasion and dirt.

[0052] Furthermore, the elastic pad is configured to allow the user to select the required type and / or required number of elastic module layers, select side enclosing members of a height that matches the total thickness of the elastic module layers, and attach the top cover, bottom cover, selected side enclosing members, and selected additional elastic pad layers together to obtain the elastic pad.

[0053] The elastic pad of the present invention allows the user to select the type and number of elastic module layers by themselves, so the total stack height of the elastic module layers is not a fixed height. For this reason, the elastic pad is provided with outer cover side enclosing members 1011 having multiple height dimensions, allowing the user to freely select. Based on this, referring to another embodiment shown in Figure 27, it is more preferable that the present invention provides fasteners between both the top cover 1012 and the side enclosing member 1011 and between the bottom cover 1013 and the side enclosing member 1011.

[0054] Incidentally, the installation of a zipper between the top cover and the side enclosing members is not a common practice in this field. Even if a zipper is installed on the outer cover of a typical bed pad, it typically requires only one zipper, which saves time during production and prevents loss of components when the outer cover is disassembled into multiple parts. Therefore, while a configuration without a zipper or a configuration with only one zipper is preferable for elastic pads such as typical bed pads, installing two zippers to divide the outer cover into three parts is clearly a worse configuration. Therefore, there is no motivation for those skilled in the art to modify a typical bed pad outer cover to one with zippers installed between the top cover and the side enclosing members and between the bottom cover and the side enclosing members.

[0055] 12 shows an example of the elastic module layer in FIGS. 7A and 7B. In the elastic pad main body 101, the elastic module layer is formed by arranging a number of elastic modules 106 on the base layer 105 of the elastic module layer so as to form an array along a plane perpendicular to the height direction. The springs in each elastic module are compressed in the height direction. In this embodiment, the base layer 105 of the elastic module layer is integrated on the bottom cover 1013. However, in other embodiments, the elastic module layer may be installed independently of the outer cover 110, so that the entire elastic module layer can be placed in or removed from the outer cover 110.

[0056] 8A-8B show an alternative embodiment to the embodiment shown in FIGS. 7A-7B.

[0057] 8A and 8B, the elastic pad main body includes two elastic module layers, the two elastic module layers including a first elastic module layer 101a and a second elastic module layer 101b located on top of the first elastic module layer 101a, and the first elastic module layer 101a and the second elastic module layer 101b are stacked such that the minor diameter axial ends of the elastic modules of the first elastic module layer 101a and the minor diameter axial ends of the elastic modules of the second elastic module layer 101b face each other. In this embodiment, the outer contour of each elastic module 106 has a conical cross section, and therefore the "major diameter axial end" and the "minor diameter axial end" can be understood to be both axial ends of the elastic module itself and have the maximum radial dimension and the minimum radial dimension of the elastic module, respectively.

[0058] More preferably, the elastic pad includes two balance net layers 104, and the two balance net layers 104 correspond one-to-one to the two elastic module layers. The size of each of the apertures corresponds to the outer diameter of the small-diameter axial end of the elastic module.

[0059] In this embodiment, a single layer structure may be installed between the first elastic module layer 101a and the second elastic module layer 101b, and the elastic module layer base layers 105 of these two elastic module layers are installed on the top and bottom surfaces of the layer structure, respectively.

[0060] 9A and 9B, the elastic pad main body includes two elastic module layers, including a first elastic module layer 101a and a second elastic module layer 101b located on top of the first elastic module layer 101a, and the first elastic module layer 101a and the second elastic module layer 101b are stacked such that the small diameter axial ends of the elastic modules 106 of the first elastic module layer 101a and the large diameter axial ends of the elastic modules 106 of the second elastic module layer 101b face each other. In this embodiment, the outer contour of each elastic module 106 has a conical cross section, so the "large diameter axial end" and the "small diameter axial end" can be understood to be both axial ends of the elastic module itself and have the maximum and minimum radial dimensions of the elastic module, respectively.

[0061] More preferably, the elastic pad includes two balance net layers 104, and the two balance net layers 104 correspond one-to-one to the two elastic module layers. The size of each of the apertures corresponds to the outer diameter of the small-diameter axial end of the elastic module.

[0062] The specific installation of the elastic module layer in each of the above several embodiments is similar, and it should be understood that all statements regarding the elastic module layer described in this invention apply to each of the elastic module layer embodiments in the embodiments shown in Figures 7A-9B.

[0063] Taking the installation of one elastic module layer as an example, the elastic modules 106 can be slid into position by track rails 108 installed on the base layer 105 of the elastic module layer (i.e., installed on the bottom cover 1013), and each track rail 108 extends along the horizontal direction. Figures 13 to 18 show a specific embodiment.

[0064] 13, each track rail 108 is removably mounted to the base layer 105 of the elastic module layer by a set of track rail mounting fixtures 107, and each set of track rail mounting fixtures 107 is installed at intervals along the extension direction of the corresponding track rail 108. There are three track rail mounting fixtures 107 in each set, and they are installed at both ends and the middle position of the track rail 108, respectively.

[0065] 14A shows the structure of each track rail mounting device 107. Each track rail mounting device 107 has a mounting device protrusion located at its top and protruding in a direction perpendicular to the extension direction of the track rail 108 and parallel to the base layer 105 of the elastic module layer, and a vertically recessed portion 1073 is formed below the protrusion. In other words, each track rail 108 includes an upper structure 1071 and a lower structure 1072, and the vertical dimension of the upper structure 1071 is larger than the vertical dimension of the lower structure 1072, so that both vertical ends of the upper structure 1071 form mounting device protrusions relative to the lower structure 1072. The mounting device protrusions and the recessed portions 1073 below them are used for coupling with the track rail 108.

[0066] Continuing to refer to FIG. 14A, the bottom of the mounting protrusion is provided with an array of fixing protrusions 1074, which are used to ultrasonically weld the mounting protrusion to the base layer 105 of the elastic module layer.

[0067] 15 to 16B are schematic diagrams showing the track rail 108 slid laterally to a predetermined position relative to the track rail mounting fixture 107. Referring to Fig. 15 to 16B, a mounting receptacle 1081 corresponding to the mounting fixture protrusion is provided at the bottom of the track rail 108, and the mounting fixture protrusion can cooperate with the mounting receptacle 1081 so that the track rail 108 can slide along its extension direction relative to the track rail mounting fixture 107 and be mounted to a predetermined position. The mounting receptacle 1081 actually forms one engaging hook 1086, which is engaged with the recess 1073 of the track rail mounting fixture 107.

[0068] 16A and 16B also show the main body structure of the track rail 108 (i.e., the structure for cooperating with the elastic module 106). Each track rail 108 includes a support wall 1082 extending from the top side to the bottom side of the track rail 108, a top joint 1083, and a bottom joint 1085. The top joint 1083 is connected to the top side of the support wall 1082 and extends toward both the left and right sides of the support wall 1082 and bends downward so that two top storage sections 1084 that open downward are formed at the top of the track rail 108. The bottom joint 1085 is connected to the bottom side of the support wall 1082 and extends toward both the left and right sides of the support wall 1082 and bends upward so that two bottom storage sections 1084 that open upward are formed at the bottom of the track rail 108.

[0069] 17 and 18, each elastic module 106 includes a cone-shaped spring and a spring bracket 106 that houses and holds the cone-shaped spring, and each of the left and right sides of the spring bracket 106 is provided with a connecting protrusion 1061, which protrudes upward from the top surface of the bottom body of the spring bracket 106 and protrudes downward from the bottom surface of the bottom body of the spring bracket 106, so that the connecting protrusion 1061 is simultaneously received by the top receiving portion 1084 and the bottom receiving portion 1084 of the track rails 108 on both the left and right sides of the elastic module 106. That is, each of the track rails 108 is provided with a structure on both the left and right sides that can be connected to the elastic modules 106 located on the left and right sides, so that the two elastic modules 106 on both sides of the track rail 108 can slide along their respective rails independently.

[0070] 14B and 14C illustrate other embodiments as an alternative to ultrasonic welding. Referring to Fig. 14B, the track rail mounting fixture may be adhered to the base layer 105 of the elastic module layer with an adhesive, and similarly includes an upper structure 1071 and a lower structure 1072, each having a recess 1073 formed therein. Referring to Fig. 14C, the track rail mounting fixture 107 is riveted to the base layer 105 of the elastic module layer with a rivet 1075, and similarly includes a mounting protrusion and a recess.

[0071] 20A to 22 show another alternative embodiment. In this embodiment, each elastic module 125 has a connecting protrusion 1251 on both the left and right sides of the spring bracket. The connecting protrusion 1251 protrudes upward from the top surface of the spring bracket body and downward from the bottom surface of the spring bracket body, so that the connecting protrusion 1251 is simultaneously received in the top and bottom receiving portions 1212 (which have receiving grooves 123 as shown in FIGS. 20A and 20B ) of the track rails 121 on both the left and right sides of the elastic module. Each track rail 121 has a structure on both the left and right sides that can be connected to the elastic modules 125 located on either side, allowing the two elastic modules on both sides of the track rail 121 to slide independently along their respective rails.

[0072] However, unlike the above-described embodiment, the track rail in this embodiment is directly fixed to the bottom cover 122 by ultrasonic welding (as shown in FIG. 20A), adhesive, or caulking with rivets 124 (as shown in FIG. 20B). In this embodiment, the installation of a track rail mounting fixture is omitted.

[0073] Another embodiment is shown in Figures 23 to 26. First, referring to Figure 24, each track rail includes a number of track rail segments, which are connected in sequence in the vertical direction. Each track rail segment has a forward-facing protrusion at its front end and a forward-facing recess at its rear end, and the protrusions and recesses of adjacent track rail segments are matched to each other, thereby connecting the adjacent track rail segments together. For example, in the adjacent track rails shown in Figure 24, the front protrusion 1312a of the first track rail 1312 extends into the forward-facing recess 1311a at the rear end of the second track rail 1312.

[0074] Referring to Figure 26, each track rail includes a base 131, a pair of connecting walls extending upward from the left and right sides of the base 131, and a pair of end walls extending opposite each other from the top ends of the pair of walls. A gap exists between each pair of end walls, and the base 131, together with the pair of connecting walls and the pair of end walls, defines a pair of receiving sections 1313 with openings facing each other, and the receiving sections 1313 are formed with receiving grooves 1314. Correspondingly, the left and right sides of the spring bracket of each elastic module are each provided with a connecting leg extending downward and a connecting protrusion 1321 extending in opposite directions from the connecting legs on the left and right sides of the spring bracket. The receiving grooves 1314 of the pair of receiving sections 1313 of each track rail can be respectively connected to the connecting protrusions 1321 of the elastic modules located on the left and right sides of the track rail. Preferably, a separation wall 1315 is installed between the two connecting walls of the base 131, and the height of the separation wall 131 is smaller than that of the connecting walls.

[0075] As can be seen by observing Figure 23 in more detail, the connecting walls installed on the left side of the base 131 are installed intermittently in the vertical direction, and the connecting walls installed on the right side of the base 131 are installed intermittently in the vertical direction, and further, the connecting walls installed on the left side of the base 131 and the connecting walls installed on the right side of the base are arranged alternately in the horizontal direction.

[0076] The above-mentioned connection forms between the elastic module and the bottom cover are all applicable to elastic pads that allow users to customize the pad according to their hardness needs.

[0077] The elastic pad in this embodiment can be removed and stored by the user himself / herself. The user can first remove the outer cover and then take out the elastic module 106 from the track rail.

[0078] Furthermore, the additional elastic pad layer 102, the top cover 102, and the side enclosing member 1011 can all be rolled up and stored. Furthermore, because the track rail or track rail mounting device is made of flexible plastic, the base layer 105 of the elastic module layer on which multiple track rails are aggregated can be rolled up and stored along a plane perpendicular to the extension direction of the track rail, and the soft track rail will not puncture and tear the bottom cover after being rolled up and stored. Although the track rail and track rail mounting device are both structures with a certain degree of stability, they are not necessarily very rigid, and it should be understood that the track rail and track rail mounting device will undergo a certain degree of deformation when subjected to a certain external force.

[0079] After the outer cover 110 of the elastic pad, the additional elastic pad layer 102, the elastic modules 106, and the elastic balance net layer 104 are separated from each other, they can be stored through the following steps: stacking the additional elastic pad layer 102 and the elastic balance net layer 104 and rolling them up together to store them to form a first storage roll, and separating the top cover 102, the side enclosing members 1011, and the base layer 105 of the elastic module layer from each other (it can be understood that fasteners are installed between the top cover 102 and the side enclosing members 1011 and between the side enclosing members 1011 and the base layer 105 of the elastic module layer), stacking them, and rolling them up together to store them to form a second storage roll.

[0080] Furthermore, each elastic module 106 is configured as a conical cross-section structure with an open bottom end and a hollow interior, and multiple elastic modules 106 are configured so that a user can remove each elastic module 106 from the track rail and then stack and store the elastic modules 106 in order along the height direction of the elastic modules to form an elastic module storage set. In the stacked state, the lower elastic module 106 of adjacent elastic modules 106 is inserted upward into the upper elastic module 106 through the lower end opening of the upper elastic module 106.

[0081] Furthermore, the user may place the first storage roll, the second storage roll, and the elastic module storage set together in a storage box. A storage box of corresponding dimensions may be provided as a product or service item in conjunction with the sale of the elastic pad, allowing the user to remove and store the elastic pad at home.

[0082] 28 shows another embodiment of an elastic pad layer, which includes an elastic pad main body 2002 and an additional elastic pad layer 2000. The elastic pad main body 2002 and the additional elastic pad layer 2000 are attached with a Velcro fastener. The elastic pad main body 2002 in this embodiment may be the same as or similar to the elastic pad main body in the other embodiments, and the additional elastic pad layer 2000 in this embodiment may be the same as or similar to the additional elastic pad layer in the other embodiments.

[0083] The present invention further provides furniture including the elastic pad of the above embodiment, and the furniture may be furniture on which a user can sit or lie down, such as a sofa, a bed, or a sofa bed.

[0084] The additional elastic pad layer of the present invention may have various structural configurations for user selection, and therefore each additional elastic pad layer is produced, manufactured, and sold as an independent product. The present invention further provides an embodiment of the additional elastic pad layer, in which the independent additional elastic pad layer includes the additional elastic pad layer in the elastic pad shown in Figures 1 to 27.

[0085] The elastic pad provided by the present invention is a high-quality elastic pad with good comfort. Compared with current similar elastic pads, the elastic pad of the present invention allows users to customize the elastic pad themselves. Compared with the technical configuration in which an additional elastic pad layer is installed inside the outer cover, this installation is more convenient for users to assemble and replace the additional elastic pad layer.

[0086] In a preferred embodiment of the present invention, the following advantages can be provided to the user: (1) The user can select corresponding accessories according to their needs to intentionally create an elastic pad that meets their intended use, and (2) when a part of the structure of the elastic pad becomes weak, the user can purchase the corresponding accessories themselves and continue to use the elastic pad by simply replacing the weakened structure.

[0087] The above description of several embodiments of the present invention is provided for the purpose of explanation to persons of ordinary skill in the relevant art. It is not intended to limit the present invention exclusively to one disclosed embodiment. As noted above, those skilled in the art will recognize other alternatives and modifications to the present invention. Thus, while several alternative embodiments have been described in detail, those skilled in the art will recognize or be relatively easy to develop other embodiments. The present invention includes all alternatives, modifications, and modifications of the present invention described herein, as well as other embodiments that fall within the spirit and scope of the invention as described above.
