A modular spring mattress

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority based on the Chinese patent application filed with the State Intellectual Property Office of China on December 14, 2023, with application number: 2023234259061, and the name of the invention: "A modular camping mattress". Part of the content of the Chinese patent application is hereby introduced into the text of this application. Technical Field

[0003] The present invention relates to a mattress, in particular to a spring mattress which is easy to assemble. Background Art

[0004] With the continuous progress of society and the continuous improvement of people's living standards, material needs have been greatly satisfied, but the quality of sleep has not improved at the same rate. How to get a good night's sleep is a common concern for people. To improve the comfort of the mattress, the springs in the mattress provide good elasticity. However, traditional spring mattresses connect the springs into one, forming a soft cushion with uniform elasticity. It cannot provide different elasticity according to the shape of the human body. At the same time, the structure is complex and cannot be assembled into parts, which is very inconvenient during transportation. Spring mattresses should not be used when camping outdoors.

[0005] In camping, "sleeping pad" refers to an item that acts as a mattress. The function of an outdoor sleeping pad is to provide warmth, comfort, and dehumidification. Comfort is an important factor in whether you can spend a good night outdoors. Even the most flat outdoor ground is inevitably uneven, with small stones, tree stumps, and other uneven surfaces. Sleeping directly on the ground will definitely be uncomfortable. In terms of sleeping pad comfort, the most common sleeping pad is the air mattress. Because it is inflatable, it is easy to carry. However, the hardness and elasticity of the air mattress are still not comparable to the spring mattress at home. The air mattress is compressed into a human body shape, which prevents the body from flattening and relaxing properly. Summary of the Invention

[0073] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0074] Referring to Figures 1 to 17, this embodiment provides an assembled spring mattress 6, including a bed frame 1 and multiple groups of spring modules 2 or several spring units 3. The multiple groups of spring modules 2 or several spring units 3 are assembled on the bed frame 1 in a detachable manner, and the disassembled multiple groups of spring modules 2 can be folded and stacked together, or several spring units 3 can be stacked together, which greatly saves storage space. In this embodiment, the spring module 2 is composed of several spring units 3.

[0075] The bed frame 1 provided in this embodiment is composed of multiple groups of frames, including two groups of different lengths, which are plugged into each other in pairs. The length of one group of frames just constitutes the long side of the bed frame 1, and the length of the other group of frames constitutes the short side of the bed frame 1. The long side array and the short side array are used. The frames of the long side and the frames of the short side are plugged into each other between the horizontal rows to form a supporting and stable structure of the bed frame 1. The plug-in between the frames is constructed to be detachable from each other, which facilitates the assembly and disassembly of the bed frame 1. When not in use, the bed frame 1 can be disassembled into a single frame for storage. Specifically, a positioning member 4 is set between the frame of one of the two groups of frames of different lengths and the spring module 2 or the spring unit 3 to form a detachable assembly.

[0076] To further reduce the storage space required for the frame, in this embodiment, the frame is configured with at least one folding structure 13 along its length, which can be used for folding and storage. This folding structure 13 can be folded according to the spring module, so that the folded and stored frame can be precisely fitted onto the stacked and stored spring units 3. Specifically, the frame has at least one mesh layer 14; each grid layer 14 is constructed so that it can fit onto at least one spring unit 3. The frame is constructed with the folding structure 13 so that, after folding, the number of grids in the frame matches the module of the spring units 3 of the spring module 2, or the module of the spring units 3 formed by stacking multiple spring units 3.

[0077] The grid layer 14 design of the frame includes that one of the groups of frames is set to include two or more grid layers 14; the other group of frames is set to include one or more grid layers 14; the number of grid layers 14 of one group of frames is greater than or equal to the number of grid layers 14 of the other group of frames.

[0078] In this embodiment, in order to be suitable for camping and easy to carry, the spring mattress 6 also includes a storage box 5. The storage box 5 has a box body and a box cover that can be opened and closed relative to each other. The box body is used to store the disassembled bed frame 1 and spring module 2.

[0079] First embodiment (see Figures 1-12)

[0080] In the first embodiment, the bed frame 1 is split into a long frame 11 and a short frame 12. The long frames 11 are arranged in vertical columns, and the short frames 12 are arranged in rows. The long frames 11 and the short frames 12 are plugged into each other. The plugging structure is provided with plugging slots 16 on the long frames 11 and the short frames 12. The plugging slots 16 are arranged at intervals of a single grid or two or more grids designed on the frame, and the depth of the plugging slots 16 is set to at least one-third of the height of the grid on the short side of the frame. The long frames 11 and the short frames 12 are plugged into each other using the plugging slots 16 to form the bed frame 1. After plugging, the sum of the depths of the corresponding plugging slots 16 on the long frames 11 and the short frames 12 is equal to the height of the grid.

[0081] Specifically, along the plug-in direction, the plug-in slots 16 on the long frame 11 are set in the lower half of a single grid, and the plug-in slots 16 on the short frame 12 are set in the upper half of a single grid. When the long frame 11 is plugged downward onto the short frame 12, the corresponding plug-in slots 16 set in the lower half are plugged into and adapted to the portion of the short frame 12 where no plug-in slots 16 are set, and the plug-in slots 16 in the upper half of the short frame 12 are just plugged into the portion of the long frame 11 where no plug-in slots 16 are set. The plug-in slots 16 are plugged into and matched with the portion where no plug-in slots 16 are set, so that the bed frame 1 can form a stable connection structure during plug-in assembly, thereby ensuring the stability of the bed frame 1 during use.

[0082] In the first embodiment, a spring module 2 is provided for assembly with the bed frame 1. The spring module 2 comprises a connecting base 21 and a plurality of spring units 3 assembled thereon. The positioning member 4 includes a groove 41 provided on the short frame 12 and a protrusion 42 provided on the connecting base 21 of the spring module 2. A set of short frames 12 is assembled into a set of spring modules 2.

[0083] Specifically, the intervals between the grooves 41 provided on the short frame 12 are equal to the base width of a single spring unit 3 provided on the spring module 2. The protrusions 42 are provided on the bottom of the low abutting sides of two adjacent spring units 3 on the spring module 2. The spring module 2 is installed and fixed on the bed frame 1 by the engagement between the grooves 41 and the protrusions 42. The adjacent grooves 41 correspondingly engage a spring unit 3 to ensure that the position of the single spring units 3 is stable and not easy to move when the mattress is under force. In this embodiment, the grooves 41 and the protrusions 42 serve as limits for the spring module 2 in the row and column directions.

[0084] Furthermore, the spring module 2 is limited in the vertical direction. The limiting setting is that a bending portion 15 is provided on both ends of the long frame 11. When the spring module 2 covers the bed frame 1, the bent end of the bending portion 15 and the base of the spring module 2 located at the outermost side form a limit. The bending portion 15 is provided at both ends of the long frame 11. On the one hand, it serves to limit the assembled spring module 2 to avoid the movement of the spring module 2 during use. On the other hand, it simplifies the limiting of the spring module 2 in the vertical column, and makes way for the assembly of the spring module 2 with grooves 41 and protrusions 42 in the row, avoiding the setting of a complex limiting structure on the long frame 11, thereby affecting the assembly efficiency of the spring module 2.

[0085] In the first embodiment, the folding and storing structure of the spring module 2 and the long frame 11 and the short frame 12 is configured such that, in the spring module 2 , the connecting base 21 is constructed such that one side of its long side has a rotating folding structure.

[0086] Specifically, the connecting base 21 includes a first base and a second base, and the first base and the second base are hinged at one side of their ends with a rotation, and the first base and the second base are arranged relative to each other at the end where the hinge is set relative to the side of the hinge to form a first clamping piece for engagement; the first base and the second base are arranged relative to each other on the sides where they are spliced ​​by rotation and on the sides where they are rotated away from each other to form a second clamping piece for engagement; the connecting base 21 is constructed with the rotation hinge so that the first base and the second base can be releasably engaged with the second clamping piece on the splicing side; or the connecting base 21 is constructed with the rotation hinge so that the first base and the second base can be releasably engaged with the first clamping piece on the rotating end.

[0087] When the first and second bases are connected using the first connectors on the rotating ends, a spring module 2 is formed for assembly to the bed frame 1. When the first and second bases are connected using the second connectors on the connecting sides, a spring module 2 is formed for folding and storage. In this embodiment, the first and second bases are each used to assemble four spring units 3, with the conical springs 33 positioned with their tapered ends facing upward.

[0088] In the first embodiment, the folding structure 13 of the split long frame 11 and the short frame 12 is set as a hinge structure. After the frame is folded with the folding structure 13, it can be mounted on the spring module 2 folded in half with the connecting base 21. It should be noted that the folding structure 13 is not limited to the hinge structure mentioned in this embodiment. Other folding structures 13 including hinge structures, latch structures, etc. are all equivalent substitutes for the hinge structure in this embodiment.

[0089] Specifically, the design of the short frame 12 is to provide a grid layer 14 including an upper and lower layers corresponding to the two layers of spring units 3 on the first base and the second base after folding, wherein the size of a single grid can be correspondingly fitted on the two spring units 3, so the short frame 12 corresponding to the connecting base 21 is set to be folded once, and the folded short frame 12 is divided into two upper and lower layers, two grids each, which are correspondingly fitted on the four spring units 3 corresponding to the first base and the second base to form storage.

[0090] The design of the long frame 11 is provided with a grid layer 14, and a single grid is correspondingly mounted on a single spring unit 3. Two folds are set on its length corresponding to the four spring units 3 on the first base or the second base after folding. After folding, it can be correspondingly mounted on the four spring units 3 on the first base or the second base to form storage.

[0091] With regard to the different designs of the grids on the long frame 11 and the short frame 12 and the different settings of the folding times, the space after folding and storage is taken into consideration. After the long frame 11 and the short frame 12 are folded and stored and put on the spring unit 3, when all the frames are stacked, the stacked height just adapts to the height of the spring unit 3 when it is initially pre-tightened. When storing, the frame is perfectly integrated with the spring unit 3, so that when storing, only the space occupied by the folded spring module 2 is left, which can better accommodate the storage box 5 and perfectly utilize the space at the height of the spring unit 3.

[0092] Regarding the design of the number of grid layers 14 on the long frame 11 and the short frame 12, in addition to utilizing the space when stored, if space permits, two or more layers of short frames 12 can be provided to increase the supporting height of the bed frame 1 when in use.

[0093] In the first embodiment, as shown in FIG9 , a spring mattress 6 is provided which is composed of a bed frame 1 and a spring module 2. The spring mattress 6 can be used by simply laying a sheet or a face cover on the mattress. The spring mattress 6 can provide the same softness and comfort as a furniture mattress, so that the mattress with springs as the mattress module can be used for camping, thereby improving the comfort of the spring mattress 6 and satisfying the convenience of the spring mattress 6. When not in use, the spring mattress 6 can be folded and stored in a storage box 5 (as shown in FIG10-13 ), which effectively saves space and is also very convenient to carry.

[0094] Second embodiment (see Figures 14-17)

[0095] The difference in the structural design of the bed frame 1 in the first embodiment compared to the first embodiment lies in the design of the assembly structure between the spring module 2 or the spring unit 3 and the frame to form the bed frame 1 .

[0096] In the second embodiment, a spring unit 3 structure is provided for assembly with the bed frame 1. The spring unit 3 includes a spring fixing seat 31 and a spring sleeve 32, which are engaged with each other, and a spring end cover 5. The spring sleeve 32 is configured to accommodate a conical spring 33 therein; the spring sleeve 32 has a cavity for stacking another spring sleeve 32, and the spring fixing seat 31 corresponds to the cavity opening to make way for stacking another spring sleeve 32.

[0097] The positioning member 4 includes a plurality of protrusions 42 provided on the short frame 12 and a groove 41 provided on the end cover 5 of the spring unit 3 , and one protrusion 42 is correspondingly inserted into one groove 41 .

[0098] Specifically, the groove 41 is provided on the end cover 5 of the spring sleeve 32 away from the spring base; the end cover is provided at the top of the conical surface of the conical spring 33. When a plurality of spring units 3 are assembled, the spring mattress 6 is formed with the spring base on the spring unit 3 forming a support area. The inverted structure of the spring unit 3 is mainly used to increase the support of the spring mattress 6 when it is used outdoors. While achieving the convenience of assembling the spring unit 3, the convenience of using the spring mattress 6 is increased. The support area is formed with the spring base facing the support area, so that a thin camping mat can be laid on the support surface to form a mattress, and the support area is large, and the stability of the mattress is better.

[0099] To ensure a stable connection between the individual spring bases within the support surface when inverted, the second embodiment provides a spring base with a plurality of connectors 34 spaced evenly along its edges. These connectors 34 connect the two spring bases, preventing the spring units 3 (wide at the top and narrow at the bottom) from unstable wobbling when subjected to force when inverted, thereby increasing the stability of the connection between the two spring units 3. For spring mattresses with a spring height of less than 15 cm, or with larger spring diameters, such as 5 or 6 cm or more, connectors 34 are not required. Such individual springs can be secured to the base plate or bed frame via positioning members. The spring shape is preferably waisted, meaning that the diameters at both ends of the spring are larger than the waist diameter.

[0100] The structure of the connecting member 34 is specifically designed as follows: the connecting member 34 includes a clamping point 341 and a clamping slot 342; a plurality of the spring units 3 are clamped with the clamping point 341 on one spring base and the clamping slot 342 on another spring base, and the spring base is constructed by clamping the clamping point 341 and the clamping slot 342 to form a support surface of the mattress.

[0101] At the same time, in order to increase its stability when used as a supporting surface, the connecting member 34 is provided with two protrusions 343 between its clamping point 341 and the clamping groove 342, and one of the two protrusions 343 is provided with a concave cavity 344 for inserting the other protrusion 343; the other protrusion 343 of one spring base is inserted into the concave cavity 344 of the other spring base.

[0102] Third embodiment

[0103] On the basis of the second embodiment, the assembly of a single spring unit 3 can be replaced by the assembly of a spring module 2. The positioning member 4 includes a plurality of protrusions 42 provided on the short frame 12 and a plurality of grooves 41 provided on the end surface of the spring unit 3 in the spring module 2. One protrusion 42 is correspondingly inserted into one groove 41. A group of the short frames 12 is assembled into a group of the spring modules 2.

[0104] Specifically, the spring module 2 consists of a connecting base 21 and a plurality of spring units 3 assembled on the connecting base 21. The grooves 41 are provided on the end surfaces of the spring units 3 facing away from the connecting base 21. When the spring module 2 is assembled with the grooves 41 and the protrusions 42, the connecting base 21 serves as the support surface for the mattress.

[0105] Similarly, in the third embodiment, the connecting base 21 is constructed so that one side of its long side has a rotating folding structure; after the frame is folded with the folding structure 13, it can be mounted on the spring module 2 folded with the connecting base 21, which is convenient for storage and carrying.

[0106] The fourth embodiment is shown in Figures 18-23.

[0107] Based on the second embodiment, a design for the assembly structure between the spring module 2 or the spring unit 3 and the bed frame 1 is proposed.

[0108] In order to increase the stable connection between the various spring bases in the support surface during inversion, in the fourth embodiment, the spring base provided includes a plurality of connecting members 34 arranged at equal intervals along its edge. The connecting members 34 serve to connect the two spring bases, thereby preventing the spring units 3, which are wider at the top and narrower at the bottom, from shaking unstably when subjected to force during inversion, and increasing the connection stability between the two spring units 3.

[0109] The structure of the connecting member 34 is specifically designed as follows: the connecting member 34 includes an elastic sheet 345 provided with a clamping block 346 and a clamping hole 347. Several of the spring units 3 are clamped with the clamping block 346 on one spring base and the clamping hole 347 on another spring base. The spring base is constructed by clamping the clamping block 346 and the clamping hole 347 to form a support surface of the mattress.

[0110] At the same time, in order to increase its stability when used as a supporting surface, the connecting member 34 is provided with two protrusions 343 between its locking block 346 and the locking hole 347, and one of the two protrusions 343 is provided with a concave cavity 344 for inserting the other protrusion 343; the other protrusion 343 of one spring base is inserted into the concave cavity 344 of the other spring base.

[0111] In the fourth embodiment, a cushioning layer 7 is provided for placement on the spring mattress 6. The cushioning layer 7 is provided with a plurality of drawstring strips 71 along its four edges. The drawstring strips 71 are detachably connected to the connector 34 of the spring unit 3. The spring unit 3 is positioned on the periphery of the spring mattress 6. The cushioning layer 7 is placed on top of the spring mattress 6 to form a semi-enclosed structure.

[0112] In the fourth embodiment, the structure of the corresponding snap strip on the cushion layer 7 and the connecting member 34 for forming a detachable connection is consistent with the connecting member 34 provided on the spring unit 3, forming a matching snap-fit ​​structure.

[0113] The fifth embodiment is shown in Figures 24-26.

[0114] In the fifth embodiment, a bed frame 1 structure is provided, which is composed of multiple sets of identical frames spliced ​​together in pairs. The frame structure is constructed as a bottom plate 17 with a grid structure 18, and the grid structure 18 has a single grid that can be used to be mounted on a single spring unit 3.

[0115] The bottom plate 17 has a splicing structure, and the bottom plates 17 are spliced ​​in pairs or with a third piece using the splicing structure. The bottom plates 17 have a detachable function and can be stacked in pairs for folding and storage, further facilitating the reduction of the storage space of the frame. In this embodiment, in order to be suitable for camping and easy to carry, the camping mat also includes a storage box, which has a box body and a box lid that can be opened and closed relative to each other, and the box body is used to store the disassembled bottom plate 17 and spring unit 3.

[0116] In the fifth embodiment, the spring mattress 6 can be assembled in conjunction with the spring unit 3 structure provided in the fourth embodiment. The positioning structure includes a protrusion 42 provided on the base plate 17 and a groove 41 provided on the end surface of the spring unit 3, with one protrusion 42 correspondingly inserted into one groove 41. This assembly structure is similar to the design of the assembly structure between the spring module 2 or spring unit 3 and the frame to form the bed frame 1 in the second embodiment.

[0117] Specifically, in the fifth embodiment, the protrusion 42 and the groove 41 are configured as a conical protrusion 42 and a conical groove 41. When the spring module 2 or the spring unit 3 is subjected to pressure, the conical downward fit is pressed tighter and tighter to form a tapered interference fit, making the insertion more stable.

[0118] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with this technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the scope of protection of the present invention.
