Description

Technical Field

[0001] The present disclosure relates to a mattress support, and in particular to a folding mattress support. Background Art

[0002] Mattress supports can provide a firm and stable support for a mattress, and mattress supports include various structures that can provide support for a mattress, such as a bed, a bed frame, a bed box (box spring), etc. However, conventional mattress supports may require tools to assemble, and pre-assembled mattress supports take up valuable storage and transportation space. Therefore, there is a need for an improved structure and method to provide a mattress support that is easy to transport and store, and the mattress support is compact and easy to assemble or disassemble. Summary of the invention

[0003] The present disclosure provides a system and method that uses a double-folding mattress support to facilitate assembly and / or disassembly. In some cases, no tools are required for assembly or disassembly. The system and method provided by the present disclosure can also provide a mattress support with a compact configuration, which can save space during storage and / or transportation. For a foldable mattress support with an irregular shape, its structure may not be convenient for handling, storage and / or transportation. Therefore, the present disclosure provides a system and method that allows a foldable mattress support to have a more compact and / or more regular shape.

[0004] Conventional mattress supports have various limitations. Therefore, there is a need for a folding mattress support that has no protruding parts in the folded state and is easy to fold and unfold, making it more ideal for packaging, storage and transportation. The system and method provided by the present disclosure are intended to solve the unmet needs of current commercial mattress supports by providing a mattress support that can be folded multiple times. Among them, after the double-fold mattress support is folded, one frame is located on the inner side, and it can be further folded by adding a set of hinge brackets. Therefore, in the folded state, the edge of the inner frame optionally does not extend beyond the edge of the outer frame. This design structure is simple and can reduce the packaging volume. In addition, the system and method provided by the present disclosure can utilize strips on the cover body for grasping to allow folding and / or unfolding of the mattress support, as well as folding or unfolding of both ends of the cover body.

[0091] Although various embodiments of the present disclosure have been shown and described herein, these embodiments are provided as examples only for those skilled in the art. Those skilled in the art may make many changes, modifications and substitutions without departing from the present disclosure. It should be understood that various substitutions using the embodiments of the present disclosure are feasible.

[0092] The system and method provided by the present disclosure are applicable to a mattress support that can be folded multiple times, so that the mattress support occupies less space and is convenient for storage and / or transportation. The mattress support that can be folded multiple times described in the present disclosure can be used as a bed box (boxspring), which is simpler and easier to fold and / or unfold.

[0093] The present disclosure discloses various embodiments of a mattress support that can be folded multiple times, including a frame that can initially be folded in the middle to form two folds, and then can be further folded inward through a set of additional hinge brackets. This can prevent the edge of the inner frame from exceeding the edge of the outer frame when folded, and can advantageously reduce the packaging size through a simple structure.

[0094] The mattress support also includes a cover at least partially surrounding the frame, and the cover may include straps on an outer surface that can be used as handles to grasp the mattress support, making it easier to fold and / or unfold the mattress support. The cover also includes one or more inner connecting strips that can be connected to the lower frame of the mattress support to prevent the cover from sliding or loosening.

[0095] Whenever the term "at least", "greater than" or "greater than or equal to" appears before the first value in a sequence of two or more values, the term "at least", "greater than" or "greater than or equal to" applies to each value in the sequence of values. For example, greater than or equal to 1, 2 or 3 means greater than or equal to 1, greater than or equal to 2, greater than or equal to 3.

[0096] Whenever the term "not greater than", "less than", or "less than or equal to" precedes the first value in a sequence of two or more numerical values, the term "not greater than", "less than", or "less than or equal to" applies to each value in the sequence. For example, less than or equal to 3, 2, or 1 means less than or equal to 3, less than or equal to 2, or less than or equal to 1.

[0097] Whenever the terms "first", "second" or "third" etc. appear before one or more topics, they are not used to indicate the order, importance or quantity of the topics; they are only used to distinguish different topics.

[0098] A mattress support helps support or elevate a mattress. The mattress support can be a bed box, platform bed, slatted base, motorized bed frame, or solid base. The mattress support can be a bed box including a frame. The mattress supports of various embodiments of the present disclosure can be used to support a mattress, a futon, a mat, or any other flat surface for resting. The mattress supports described in the present disclosure include a bed box, and in some embodiments, the mattress support can be placed under the mattress for sleeping. The size of the mattress support can match the size of the mattress (e.g., a double, single, queen, or king size mattress support). The mattress support can include a frame and / or a cover, which can be detachable from the frame or not.

[0099] The frame provides structural support for the mattress support. The frame can be made of a rigid material. In some cases, the mattress support frame can be made of metal or metal alloys, composite materials, plastics, wood, or other materials. The mattress support frame can be formed from a plurality of interconnectable components. A foldable mattress support includes a foldable frame that can include one or more components that can pivot and / or slide relative to each other.

[0100] According to one or more embodiments of the present disclosure, Figure 1A-1B An embodiment of a multi-fold mattress support in an unfolded state is disclosed. The mattress support is in the unfolded state when the mattress support is used to support a mattress or other resting surface. The mattress support is in the unfolded state when the mattress support is in use.

[0101] like Figure 1AAs shown, the foldable mattress support 100 of this embodiment includes a plurality of ends, such as a first end 110 and a second end 120, each of which is connected to a folding portion 130, and the folding portion 130 is optionally located at the center of the mattress support. In the present disclosure, the portion close to the folding portion 130 is the proximal end, and the portion away from the folding portion 130 is the distal end. The distal distance of the folding portion 130 from the first end 110 is the same as the distal distance of the folding portion 130 from the second end 120. The first end 110 and the second end 120 optionally have the same length, width and / or height. The mattress support is substantially symmetrical along the folding portion 130. The folding portion may be a plate unit as shown in this embodiment, and in other embodiments, the folding portion may also include a plurality of support sheets.

[0102] The first end of the mattress support may be connected to the fold with the second end. The first end of the mattress support may be movable relative to the second end. The first end of the mattress support may pivot relative to the second end of the mattress support at the fold.

[0103] In some cases, the mattress support has two ends, and the two ends can be connected to a single folded portion. In some cases, the mattress support can also have three, four, five, six or more sections, which can be connected to one or more folded portions.

[0104] The mattress support may include an upper frame 140 and a lower frame 150, and each end may include an upper frame and a lower frame. For example, the first end 110 may include a first upper frame 141 and a first lower frame 151. The second end 120 may include a second upper frame 142 and a second lower frame 152. The upper frame 140 of the mattress support may include one or more upper frame sections, such as a first upper frame 141 and a second upper frame 142. The lower frame 150 of the mattress support includes one or more lower frame sections, such as a first lower frame 151 and a second lower frame 152.

[0105] When the mattress support is in the expanded state, the upper frame is substantially parallel to the lower frame. When the mattress support is in the folded state or in the folded state, the upper frame and the lower frame also remain substantially parallel. There is a space between the upper frame and the lower frame. In some cases, the distance between the upper frame and the lower frame can be set up with one or more vertical brackets 170. The vertical brackets can optionally be composed of one or more vertical rods. The vertical rods can be pivoted relative to the upper frame and / or the lower frame so that the distance between the upper and lower frames changes during the process of folding and / or expanding the mattress support. When the mattress support is in the expanded state, the vertical rods can be substantially perpendicular to the upper frame and / or the lower frame.

[0106] Any description of the upper frame and the lower frame herein may apply to any first frame and second frame of a mattress support that may be provided, regardless of the orientation of the mattress support. Any description of the upper frame may apply to the mattress support surface that contacts the mattress when the mattress support is in use. When the mattress support is in use, the lower frame is closer to the ground relative to the upper frame. The lower frame is located on a side of the mattress support opposite the upper frame, on a side facing away from the mattress contacting surface. In some cases, the upper frame and the lower frame may be substantially identical or mirror images.

[0107] Alternatively, there may be one or more differences between the upper frame and the lower frame. For example, the upper frame may optionally include one or more support structures 180, such as rods, bands, grids, coils, slats, or other types of support structures. These support structures allow a mattress or other resting surface placed thereon to have an adequate support surface. The support structures may enhance user comfort. The lower frame may also optionally include support structures, or the lower frame may include less support structures than the upper frame, which may result in a lighter mattress support weight.

[0108] Optionally, other differences are also included. The lower frame includes one or more end rods 161, 162, which can be pivoted relative to the rest of the lower frame. The first end 110 includes a first lower frame 151 having a first end rod 161, and the second end 120 may include a first lower frame 152 having a second end rod 162. In some embodiments, the upper frame does not include end rods that can be moved relative to the rest. In some cases, the movable end rods are preferably located in the lower frame because there are fewer interfering support structures on the lower frame compared to the upper frame. In alternative embodiments, one or more end rods may also be alternatively set on the upper frame, or in addition to the end rods of the lower frame. Any description herein of the movable end rods of the lower frame may also apply to embodiments of movable end rods set on the upper frame.

[0109] like Figure 1B As shown, the mattress support can also be relative to Figure 1A The mattress support can be inverted as shown, with the upper frame on the ground. In some cases, the mattress support is configured so that when the mattress is placed on the mattress support, the mattress support has the upper frame at the top. The mattress support is optionally configured so that when the mattress support is not in use, the upper frame is flipped to the bottom, ready for storage. For example, the mattress support is configured so that when the mattress support is assembled and / or disassembled, the lower frame is at the top. As further described below, the mattress support can be configured so that the lower frame folds upon itself in the folding portion, so that the first lower frame 151 folds toward the second lower frame 152.

[0110] According to one or more embodiments of the present disclosure, Figure 2A-2CSchematic diagrams of a multi-fold mattress support in the folding process and in a folded state are schematically shown. The multi-fold mattress support may include one or more folding portions. For example, the mattress support 200 includes a middle folding portion 230, which may substantially bisect the mattress support along the length of the mattress support. The first end 210 and the second end 220 of the mattress support may be movable relative to each other, and the first end 210 and the second end 220 may meet at the middle folding portion 230. When the mattress support is folded, the first lower frame 251 may fold toward the second lower frame 252.

[0111] The multi-fold mattress support may also include one or more other folds in place of the middle fold 230, or in addition to the middle fold 230. For example, the mattress support may include one or more end rods 261, 262 movable relative to the lower frame 250. The end rods may be folded at one or more distal folds 271, 272. For example, when the mattress support is folded, the first end rod 261 may pivot relative to the first lower frame 251 about the first distal fold 271, and the second end rod 262 may pivot relative to the second lower frame 252 about the second distal fold 272.

[0112] Furthermore, although a middle fold 230 and distal folds 271, 272 are shown and described, additional middle folds may be present. For example, one or more folds may be included between the middle fold and the distal fold of the lower frame, or one or more folds may be included between the middle fold and the distal fold of the upper frame. Other embodiments may include three, four, five, six, seven, eight, nine, ten or more folds.

[0113] As mentioned above, although the end bars are described as being supported by the lower frame, alternative embodiments may also allow the end bars to be supported by the upper frames 240 (the first upper frame 241 and the second upper frame 242) to be folded relative to each other.

[0114] like Figure 2A As shown, the two end portions can be folded along the middle folding portion 230, and the middle folding portion is roughly located in the middle of the mattress support. In the folded state, the first lower frame 251 and the second lower frame 252 can be folded with each other, so that the lower frame is located on the inner side and the upper frame (the first upper frame 241 and the second upper frame 242) is located on the outer side, and the inner frames are closer to each other than the outer frames.

[0115] During the folding process, the distal end of the lower frame will protrude from the distal end of the upper frame, and the end rods 261 and 262 will protrude from the distal end of the upper frame. During the folding process, the first lower frame 251 of the first end portion 210 can be substantially parallel to the first upper frame 241 of the first end portion 210, and the second lower frame 252 of the second end portion 220 can be substantially parallel to the second upper frame 242 of the second end portion 220. During the folding process, the side surface of the first end rod 261 remains substantially flush with the side surface of the remaining portion of the first lower frame 251, and the side surface of the second end rod 262 remains substantially flush with the side surface of the remaining portion of the second lower frame 252.

[0116] like Figure 2B As shown, the end rods of the lower frame can be connected to the corresponding lower frame by connecting the distal folding parts 271, 272. The end rods can move relative to the lower frame, and the end rods can move in a rotational manner around a pivot point set at the distal folding part. In some cases, the distal folding part may include a hinge bracket, which will be described in detail later. In this embodiment, the end rods cannot move parallel to the lower frame, but in some alternative embodiments, one or more grooves can be provided to allow the end rods to move parallel.

[0117] Each end bar 261, 262 can be folded independently, and the end bar can be folded by rotating about the distal fold. In some cases, the distal fold 271, 272 can cause the end bar to fold inward. When folding inward, when the first end and the second end of the mattress support are folded together, the end bar can fold inward. When folding inward, the end bar can fold toward the middle fold and away from the upper frame. When folding inward, the end bars can fold toward each other, rather than away from each other. The end bars can fold in the same direction as the lower frame folds, for example, if the portions of the lower frame are folded toward each other, the end bars can fold toward the adjacent portions of the lower frame.

[0118] In some cases, the user may select the order in which to fold the mattress support. For example, the user may select to fold along the middle fold first, and then fold the distal folds. Alternatively, the user may select to fold one or more distal folds first, and then fold the middle folds. In some cases, the middle folds may be partially folded before the distal folds are folded, and then the middle folds may be fully folded.

[0119] Figure 2CAn example of a mattress support in a folded state is shown. The mattress support can be folded around its middle fold 230 and two or more distal folds 271, 272. The first lower frame 251 and the second lower frame 252 located on the inner side can be folded towards each other around the middle fold. The inner frame can be a lower frame or an upper frame of the mattress support. The first upper frame 241 and the second upper frame 242 located on the outer side can be folded to be substantially outside the inner frame. When the mattress support is in the folded state, the inner frame can be located between the outer frames.

[0120] The end bars 261, 262 can be folded around the distal folding portions 271, 272 toward the inner frame. When the mattress support is in the folded state, the end bars can be located between the inner frames. When in the folded state, the end bars can be in contact with each other or not. When in the folded state, the side surfaces of the end bars can be substantially parallel to the side surfaces of the inner frames. The end bars can be folded inwardly toward the inner frames.

[0121] In some cases, when the mattress support is folded, the distal folds 271, 272 of the inner frame may be located at or near the distal ends 291, 292 of the outer frame. The end bars may be folded so that the end bars do not extend beyond the distal ends of the outer frames. When the mattress support is in a folded state, the end bars may be folded so that the distal ends of the end bars point toward the middle fold and the end bars do not extend beyond the length of the outer frames of the mattress support. In alternative embodiments, the end bars may or may not fold outwardly but do not extend beyond the length of the outer frames. Such a mattress support may advantageously provide a more compact structure relative to having only a single middle fold. Such a multiple fold mattress support is more compact in structure than a simple double fold mattress support.

[0122] Furthermore, by allowing the end bars to fold inward, the end bars can be prevented from hitting the outer frame and can be folded more easily. The configuration can be simplified by allowing the end bars to fold in the same direction as the inner frame, and only the end bars on the inner frame need to be folded, without any folding of the outer frame. This makes it easier to simplify the configuration and is not prone to damage or other related situations. The mattress support as described above can provide a multi-fold mattress support, including a first frame and a second frame, wherein only the first frame is further folded inward without folding the second frame. The end of the first frame optionally does not exceed the length of the second frame.

[0123] Such a multiple fold mattress support can advantageously achieve a compact configuration, wherein the length and / or width of the mattress support in the folded state is less than the length and / or width of the mattress support in the unfolded state or the double folded state. As previously described, any number of folds can be performed. In some cases, three folds can be performed with one middle fold and two distal folds, which can produce a four-fold folded mattress support, or can be otherwise referred to as a four-fold mattress support. In some cases, the number of folds can be 1+2N, where N is one of 1, 2, 3, 4, or a greater integer.

[0124] According to one or more embodiments of the present disclosure, FIGS. 3A-3C show side views of a multi-fold mattress support. Such a multi-fold mattress support may include a first lower frame and a second lower frame, a first upper frame and a second upper frame. The lower frame includes a first lower frame and a second lower frame, and the lower frame may include one or more folds. The upper frame includes a first upper frame and a second upper frame, and the upper frame may include one or more folds. For example, the lower frame 300 includes a first lower frame 310 and a second lower frame 320, and the first lower frame 310 and the second lower frame 320 may be folded along a middle fold 330. The middle fold may roughly bisect the mattress support along the length of the mattress support. The lower frame may also include one or more other folds that replace the middle fold 330, or include other folds in addition to the middle fold 230. For example, the lower frame may include one or more end rods 361, 362, and the end rods may be movable relative to the lower frame 300. The end rods may be folded at one or more distal folds 371, 372. For example, when the mattress support is folded, the first end rod 361 may rotate relative to the first lower frame 310 around the first distal folded portion 371 , and the second end rod 362 may rotate relative to the second lower frame 320 around the second distal folded portion 372 .

[0125] In some embodiments, the end bars may fold inwardly toward each other. In alternative embodiments, the end bars may fold outwardly away from each other. In some cases, the distal folding portion may be configured so that the end bars can fold in either direction (inwardly or outwardly). In some cases, the distal folding portion may be configured so that the end bars fold only in a single direction (e.g., only inwardly or only outwardly). The angle and / or direction of the folding may be controlled by the configuration of the hinge, as will be further described in other subsequent sections of this disclosure.

[0126] 3A , the lower frame 300 includes a first lower frame 310 and a second lower frame 320 , and the lower frame 300 is folded along a middle folding portion 330 . In some embodiments, the upper frame includes a first upper frame and a second upper frame, and the upper frame can be folded along the middle folding portion 330 .

[0127] As shown in FIG. 3B , when the mattress support is folded, the first end bar 361 can rotate relative to the first lower frame 310 about the first distal fold 371, the second end bar 362 can rotate relative to the second lower frame 320 about the second distal fold 372, and the end bars 361 and 362 can be folded inwardly toward the inner frame. Therefore, in the folded state, the edge of the inner frame can optionally not exceed the edge of the outer frame. The multi-fold mattress support of the present disclosure provides a compact configuration, so that space can be saved during storage and / or transportation. Since a mattress support with an irregular shape when folded is not convenient to handle, store and / or transport, the multi-fold mattress support of the present disclosure allows for a more compact and / or more regular shape in a foldable mattress support. In some embodiments, the upper frame does not include an end bar that is movable relative to the rest of the upper frame. In some cases, it is preferred that the movable end bar is located on the lower frame, and there may be less interfering support structure on the lower frame than on the upper frame. In an alternative embodiment, one or more end bars may be pivotally connected to the upper frame instead of the lower frame. Or in addition to the end rods being pivotally connected to the lower frame, one or more end rods are also pivotally connected to the upper frame. Any description of the movable end rods on the lower frame in the present disclosure can also be applied to the embodiments of the movable end rods on the upper frame.

[0128] Figure 3C A foldable mattress support is shown in an unfolded state with the lower frame at the top. The systems and methods provided by the present disclosure describe a multi-fold mattress support that may include one or more folding portions so that a user can fold and / or unfold the mattress support without using tools. By eliminating the need for tools, the assembly process becomes simpler and more convenient for the user. The user can easily assemble the mattress support without having to find or use additional tools, thereby saving time and effort.

[0129] According to one or more embodiments of the present disclosure, Figure 4A An example of an end bar 400 is shown. The end bar may be supported by a frame portion of a mattress support, the end bar being movable relative to the mattress support frame portion. The end bar may be rotated relative to the mattress support frame at a distal fold. The end bar may be pivotally connected to the frame portion by means of a hinge bracket. Further details and examples of hinge brackets are provided in greater detail elsewhere herein.

[0130] The end bar 400 may include one or more side portions 421, 422 connected by a transverse connector 410. The one or more side portions are generally perpendicular to the transverse connector, and the side portions are substantially parallel to each other. In some cases, when the mattress support is in the expanded state, the side portions remain substantially flush with the corresponding support frame portion. Alternatively, the side portions may be at a specific angle relative to the support frame. The end bar includes one or more pivot points 431, 432, allowing the end bar to rotate at the distal fold portion about the one or more pivot points.

[0131] In some embodiments, the end of the end rod connected to the distal folding portion (or referred to as the connecting end) can be designed to be more easily folded. For example, the connecting end includes a vertical cut 442 that is substantially perpendicular to the length direction of the side portion 422. Optionally, the connecting end also includes an oblique cut 441 that is inclined relative to the vertical cut. Further details about the shape and configuration of the connecting end will be provided in more detail elsewhere in this article.

[0132] The end rod 400 may be connected to the support frame portion by a hinge bracket that allows the end rod to rotate relative to the support frame portion. The connecting end of the end rod and the support frame portion may be pivotally connected to the hinge bracket by one or more bolts or other mechanisms that allow rotation.

[0133] According to one or more embodiments of the present disclosure, Figure 4B Stereoscopic views of various embodiments of hinge brackets 450a, 450b, and 450c are shown. The hinge bracket can be formed by a single integral piece 450a, or it can be formed by multiple pieces connected together to form 450b. The hinge bracket optionally has a cross-sectional shape that is generally "H" or "I". The hinge bracket includes a first side portion 461, a second side portion 462, and an intermediate connecting portion 463, wherein the first side portion 461 and the second side portion 462 each include two generally parallel protruding surfaces, and the protruding surfaces are generally perpendicular to the intermediate connecting portion. The protruding surfaces optionally have rounded outer edges, and the protruding surfaces may also have angular edges (e.g., vertical straight edges).

[0134] In some embodiments, the connection portion can be formed by a single integral piece 450a. In some examples, the connection portion can also be formed by two attachment surfaces, such as 450b, and the connection portion can be attached by bonding, fusion, welding, brazing, mechanical fasteners or any other technology. The attachment surfaces of the connection portion can be directly in contact with each other without a gap, or optionally there can be gaps between multiple surfaces, such as 450c.

[0135] The hinge bracket includes a plurality of bolt holes. For example, the hinge bracket is provided with a first bolt hole 471 and a second bolt hole 472, and the bolt holes can be positioned so that there is at least one bolt hole on each side of the hinge bracket. The bolt holes are provided on respective protruding surfaces, each protruding surface can include a bolt hole, and the bolt holes on parallel surfaces can be aligned.

[0136] The hinge bracket may optionally include a gap groove 480. The gap groove is located in the middle of the hinge bracket, between the bolt holes, and the gap groove 480 may extend through the connecting portion 463. The gap groove may have any shape and size. In some cases, the gap groove may have a larger diameter and / or circumference than the bolt hole. The gap groove is along a plane direction that is approximately perpendicular to the plane direction of the bolt hole. The gap groove has an axis perpendicular to the plane of the gap groove, and the axis extends along the longitudinal direction of the hinge bracket. The gap groove is located between the two protruding surfaces, and the edge of the connecting portion may surround the outside of the gap groove. The hinge bracket may optionally include a side opening 490, which provides a passage for the gap groove 480, and the side opening is substantially coplanar with the bolt hole, and the plane of the side opening is substantially perpendicular to the plane direction of the gap groove.

[0137] The clearance groove advantageously provides sufficient space for the connecting end to rotate freely within the hinge bracket, ensuring that there is no interference or binding between the hinge bracket and the connecting end, so that the hinge bracket and the connecting end can move and operate smoothly. The clearance groove can accommodate slight misalignment between the hinge components. If the bolt is not perfectly aligned with the hinge bracket, the clearance groove allows some lateral movement, reduces the risk of binding or excessive friction, and also serves as a channel for applying lubrication to the hinge mechanism.

[0138] The hinge bracket can be formed by processing a single piece. In some cases, the hinge bracket can also be formed by connecting two U-shaped units to each other. In some embodiments, the hinge bracket can be formed by welding two units. The hinge bracket units can be connected by welding, fusing, brazing, bonding, mechanical fasteners or any other technology. In some embodiments, the hinge bracket can be made by a stamping process. In some embodiments, the hinge bracket can be made by riveting, bolting, bonding or snap-fitting. In some embodiments, the hinge bracket can be made of steel, iron, aluminum, brass, steel alloy, brass alloy, aluminum alloy, zinc alloy, bronze alloy, nickel alloy, titanium alloy. The hinge bracket can be made of a different or the same material as the mattress support. The hinge bracket can be made of a material with sufficient strength and load-bearing capacity to support the mattress support and allow the mattress to be used comfortably. The hinge bracket can be made of a durable and long-lasting material to ensure the life of the mattress support. The hinge bracket can be made of a material that minimizes friction and ensures smooth movement to reduce the noise generated by the mattress support during folding and unfolding.

[0139] According to one or more embodiments of the present disclosure, Figure 5A-5B Further examples of hinges and hinge brackets are shown. In some cases, the first hinge bracket is used to connect the end rod and the lower frame. The connecting end of the end rod and the lower frame is pivotally connected to the hinge bracket by a bolt. The connecting end of the end rod and the lower frame, the hinge bracket, and the bolt together form a hinge. Two bolt holes are located on each side of the hinge bracket, with a gap groove in the middle. Figure 5A Various embodiments of hinge brackets are shown. Figure 5A The first embodiment shown shows a hinge bracket formed by connecting two U-shaped units. In some embodiments, the hinge bracket can be made of the same material as the lower frame of the mattress support. Figure 5B The state of the connecting end of the end rod and the lower frame in the hinge bracket when in the unfolded state is shown. In some embodiments, the connecting end is pivotally connected to the hinge bracket by a hexagonal bolt, a hexagonal bolt, a round head square neck bolt, a shoulder bolt, a countersunk bolt, a flange bolt, a stud bolt, etc. In some embodiments, the connecting end and the hinge bracket are pivotally connected by a detachable pin, a fixed pin, a knurled pin, a tapered pin, a U-shaped clip pin, a shoulder bolt, a hollow pin or other mechanism that allows pivoting. In some embodiments, the connecting end and the hinge bracket are pivotally connected by a fixed shaft, an adjustable shaft, a threaded shaft, a split shaft, a hollow shaft, a tapered shaft or a key shaft. In some embodiments, the connecting end and the hinge bracket are pivotally connected by a solid rod, a threaded rod, a hollow rod, a tapered rod, a split rod, an adjustable rod, a key rod, a knurled rod, a piston rod or an adjustable length rod. In some embodiments, the pivoting bolts, pins, rods and shafts can be made of steel, iron, aluminum, brass, steel alloys, brass alloys, aluminum alloys, brass alloys, zinc alloys, bronze alloys, nickel alloys, titanium alloys.

[0140] As previously described, one or more clearance slots 580 may be provided on the hinge bracket. The clearance slot may form one or more openings that may provide access to the middle portion of the hinge bracket. The clearance slot may be a hole formed in a single integral piece, may be formed by openings in two or more pieces connected to each other, or may pass through multiple pieces connected together. A side opening 590 may optionally provide access to the clearance slot, the side opening being substantially coplanar with the bolt hole, and the plane of the side opening being substantially perpendicular to the plane of the clearance slot.

[0141] As previously described, the end bar 550 may optionally include a vertical cutout 555 and / or an oblique cutout 557. The end bar may be pivotally connected to the hinge bracket at the first bolt hole. The oblique cutout is at a non-perpendicular and / or non-parallel angle relative to the vertical cutout. Optionally, the vertical cutout is substantially parallel to the middle portion of the hinge bracket when the end bar is deployed (e.g., the mattress support is in a fully deployed position).

[0142] In some embodiments, a portion 530 of the support frame is connected to the hinge bracket. The support frame is capable of bearing the weight of the end rod, and the support frame portion 530 includes a vertical cutout 535 and / or an oblique cutout 537. The support frame portion can be pivotally connected to the hinge bracket at the second bolt hole. The second bolt hole and the first bolt hole are respectively located at different ends of the hinge bracket, and the oblique cutout is at a non-vertical and / or non-parallel angle relative to the vertical cutout. Optionally, when the end rod is opened (for example, the mattress support is in a fully extended position), the vertical cutout of the support frame portion is substantially parallel to the middle portion of the hinge bracket, and the vertical cutout of the support frame portion is substantially parallel to the vertical cutout of the end rod.

[0143] According to one or more embodiments of the present disclosure, Figure 6 FIG. 6 shows an example of a hinge bracket 600 including a gap slot 630 in an unfolded state. Figure 6 As shown, the gap groove is located in the middle part of the hinge bracket, and the plane where the gap groove is located is substantially perpendicular to the plane where the bolt holes and / or the protruding surface are located. The gap groove is located between the bolt holes on both sides of the length direction of the hinge bracket. The gap groove is optionally not coplanar with the bolt holes. The hinge bracket has a middle part 635, and the middle part forms a plane, and the gap groove is arranged on the plane. The middle part can be connected to the protruding surface, and the gap groove is formed as an opening in the middle part. Optionally, the side opening 690 can provide a passage to the gap groove 630.

[0144] The end bar 610 is connected to the hinge bracket 600. The end bar can rotate relative to the hinge bracket about a pivot axis, and the pivot axis is at the same position as the center of the bolt hole. In some cases, in the unfolded state, the end bar can only fold in a single direction (e.g., only inward or only outward). In some alternative embodiments, starting from the unfolded state, the end bar can fold in either direction (e.g., inward or outward).

[0145] The end bar has an end portion, and the end portion includes a vertical cutout 611 and an oblique cutout 612. The vertical cutout may be perpendicular to the length direction of the end bar extending toward the hinge bracket. The oblique cutout is at a non-vertical and / or non-parallel angle relative to the length direction of the end bar extending toward the hinge bracket.

[0146] A portion 620 of the support frame (optionally a lower frame) is capable of bearing the weight of the end rod, and the support frame 620 includes an end portion having a vertical cutout 621 and an oblique cutout 622. The vertical cutout may be perpendicular to the length direction of the support frame extending toward the hinge bracket. The oblique cutout is at a non-perpendicular and / or non-parallel angle relative to the length direction of the support frame extending toward the hinge bracket.

[0147] The vertical cutout 611 of the end bar is substantially parallel to the vertical cutout 621 of the support frame portion. There is a gap between the vertical cutout 611 of the end bar and the vertical cutout 621 of the support frame portion, and the distance between the vertical cutout 611 of the end bar and the vertical cutout 621 of the support frame portion is substantially equal to the thickness of the middle portion 635, which is also substantially equal to the thickness of the gap slot. When the mattress support is in the unfolded state, the vertical cutout substantially abuts against the middle portion of the hinge bracket. The gap slot provides space to prevent the two vertical cutouts from contacting and interfering with each other when the end bar and / or the support frame portion rotates around the hinge bracket.

[0148] The purpose of the gap groove is to avoid interference between the end rods and the connecting ends of the support frame (such as the lower frame) when folded. In some embodiments, the width of the gap groove is at least about 0.5 mm, at least about 1 mm, at least about 2 mm, at least about 3 mm, at least about 4 mm, at least about 5 mm, at least about 6 mm, at least about 7 mm, at least about 8 mm, at least about 9 mm, at least about 10 mm, at least about 11 mm, at least about 12 mm, at least about 13 mm, at least about 14 mm, at least about 15 mm, at least about 16 mm, at least about 18 mm, or at least about 20 mm or more. The width of the gap groove can be less than any value provided herein, or within a range between any values ​​provided herein. In some embodiments, the gap groove is omitted. Figure 6 As shown, an opening 690 is provided on the side of the hinge bracket. In some embodiments, the shape of the opening can be rectangular, square, pentagonal, hexagonal, octagonal, dodecagonal, circular, semicircular, elliptical or curved.

[0149] like Figure 6 As shown, the connecting end of the end rod and the lower frame is pivoted to the hinge bracket by a bolt or other mechanism that allows pivoting through the bolt hole. In some embodiments, the connecting end includes a vertical cut, and in some embodiments, the connecting end also includes an oblique cut. The purpose of the oblique cut is to avoid interference between the connecting ends of the end rod and the lower frame when folded. The vertical cut and the oblique cut meet at the center position of the connecting end, which is aligned with the center point of the bolt hole. In some embodiments, the oblique cut is not perpendicular to the vertical cut. In some embodiments, the inclination angle of the oblique cut relative to the vertical cut can be about 5°, about 10°, about 15°, about 20°, about 25°, about 30°, about 35°, about 40°, about 45°, about 50°, about 55°, about 60°, about 65°, about 70°, about 75°, about 80°, about 85°. The inclination angle can be greater than or less than any value provided herein, or within a range between any values ​​provided herein.

[0150] The angle of inclination affects the distance between the edge of the bevel cut and the bolt hole, i.e. Figure 6As shown in W1, the distance W1 can be optimized by selecting the tilt angle. A shorter W1 can prevent the connection ends from contacting each other, allowing them to rotate freely in the hinge bracket without interference. However, shortening the distance W1 will reduce the connection strength of the hinge. W1 and the thickness of the gap groove can be selected to provide sufficient connection strength while allowing free rotation of each connection end. In some cases, the value of W1 can be approximately 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm or more. W1 can be less than or greater than any size provided herein, and / or be within a range between any values ​​provided herein.

[0151] When the mattress support is in the expanded state, the vertical cutouts 611 and 621 can be optionally abutted against the middle portion 635, which can stop the end rod in the fully expanded state to prevent excessive rotation. The end rod can stop at a position after the length direction of the side of the end rod is substantially in line with the connecting portion of the support frame.

[0152] In some cases, the width of the hinge bracket substantially matches the corresponding connecting end. Alternatively, the hinge bracket may also have a width that is greater than or less than the corresponding size of the connecting end.

[0153] According to one or more embodiments of the present disclosure, Figure 7 The hinge bracket 700 with the clearance slot 730 is shown in a folded state. Figure 7 As shown, the clearance slot is located in the middle portion 735 of the hinge bracket, and bolt holes 701 and 702 are respectively provided on both sides of the middle portion 735. The connecting end of the end rod and the lower frame is pivotally connected to the hinge bracket by bolts or other mechanisms that allow pivoting through the bolt holes. During the folding process, the bevel cut 712 shortens the bottom length of the connecting end, such as Figure 7 As shown, this bevel cut helps to avoid interference between the connecting ends. In some embodiments, the bevel cut can replace the clearance groove of the hinge bracket, or the clearance groove and the bevel cut can be used in combination.

[0154] like Figure 7 As shown, during the folding process of the mattress support, the connecting end can rotate around the bolt hole so that the end rod folds inward. When fully folded, the vertical cutout 711 of the connecting end forms a straight line horizontal at the top edge of the hinge bracket, and will also be flush with the end rod 291 of the upper frame in the folded state, as shown in FIG. Figure 2C When in the expanded state, Figure 6 As shown, the vertical cutout at the connecting end can abut against the inner side of the hinge bracket. The vertical cutout can prevent the end rod and the lower frame from rotating in opposite directions, thereby providing stable support in the unfolded state.

[0155] Due to the presence of the bevel cuts and / or clearance grooves, the connecting ends of the end bars and the support frame portion do not interfere with each other when the mattress support is folded and / or unfolded. Specifically, the intersection 750 of the vertical cut and the bevel cut between the two connecting ends does not contact each other regardless of how the end bars and / or the support frame portion rotates. Similarly, the intersection 760 of the bevel cut between the two connecting ends and the side of the connecting end does not contact each other regardless of how the end bars and / or the support frame portion rotates. This allows the end bars to rotate smoothly and freely during the folding and / or unfolding of the mattress support.

[0156] According to one or more embodiments of the present disclosure, Figures 8A-8B A schematic diagram of a mattress support 800 (including a cover) in an expanded state is shown. The mattress support includes a support frame and a cover, and the support frame provides a lower structure. The support frame is at least partially or completely covered by the cover. As shown in Figure 8A, the multi-fold mattress support in the expanded state is covered by the cover. The cover can be expanded around the entire body of the mattress support, covering the first end and the second end. The cover can be expanded around the entire body of the mattress support, covering the upper frame and the lower frame. In some embodiments, the cover can be made of fabric, leather, plastic, webbing, mesh material, rubber. In some embodiments, the cover can be made of cloth, cotton, linen, silk, wool, polyester, rayon, nylon, spandex, velvet, satin, denim, flannel, chiffon, taffeta, tweed, corduroy, wool, vinyl or any combination of materials. The cover can be made of a stretch material. In some cases, one or more portions of the cover can be substantially rigid. The cover can include a single layer structure. Alternatively, one or more portions of the cover can include a multilayer structure. In some cases, one or more portions of the cover may be cushioned and padded. Optionally, one or more portions of the cover may be reinforced in one or more areas for additional strength or durability. Different portions of the cover may be formed of different materials or combinations of materials, or the entire cover may be formed of the same material or combinations of materials. The cover may be sized to accommodate a mattress support of 825 in height.

[0157] As shown in Figure 8A, the upper frame faces upward, that is, the mattress support portion 810 that contacts the mattress faces upward. In some embodiments, the upper surface of the cover or the side of the cover that contacts the mattress may include one or more openings 815, which are closable and / or reopenable. The opening is used to remove the cover from the frame below. The opening can span a portion of the width or nearly the entire width of the mattress support. The opening includes one or more lateral portions that can extend along at least a portion of the length of the mattress support.
