Description
Technical Field
[0001] This invention relates to the field of bedding, specifically to a mattress and its processing method. Background Technology
[0002] Existing mattresses typically consist of multiple layers, including a support layer and a comfort layer. Each layer can be processed using different elastic materials as needed. Foam, due to its ease of processing, is often used as the comfort layer. During processing, the foam can be processed to achieve the desired firmness, and then cut into a flat mattress shape. Because the foam is cut from a large block of raw material with uniform firmness, the comfort layer has a flat top and bottom surface, and all areas have the same firmness, failing to provide differentiated support for different body sections. To address this, modular strips with varying firmness are incorporated into the mattress. These strips are fixed to the mattress at the bottom and flush at the top, forming a support surface for the user. The modular strips are detachably attached to the mattress, allowing the user to adjust the placement of the strips to their preferred firmness, creating a zoned structure that meets individual user needs. However, this type of structure has the following drawbacks: On the one hand, in order to obtain differentiated support, it is necessary to provide modular strips with differentiated hardness for the pad. The modular strips are formed by processing raw materials with different hardness. Different raw materials need to be cut separately to obtain the pad and the modular strips with different hardness. This not only makes the processing steps cumbersome and the processing efficiency low, but also generates a lot of waste during cutting due to the irregular surface contours of the pad and the modular strip, which increases the raw material cost.
[0003] On the other hand, in order to facilitate disassembly and maintenance, an assembly gap is reserved between adjacent module strips. This can cause the module strips to wobble and slip when subjected to external forces, which may lead to disengagement and affect the reliability of the connection. It can also cause uneven textures to form on the support surface due to the assembly gap, which may cause a foreign object sensation to the user. Furthermore, the module strips may affect the vertical support due to lateral deformation, which may affect the user experience. Summary of the Invention To address the shortcomings of existing technologies, this invention provides a double-layer self-locking mattress and its processing method. The mattress comprises a hard pad and a soft pad with varying degrees of firmness. While cutting to form their respective irregularly shaped self-locking zones, hard strips and soft strips are simultaneously cut. This allows for the creation of partitions with varying sizes and quantities within the irregularly shaped self-locking zones of the hard and soft pads by combining the hard and soft strips, meeting the diverse support needs of different users and enhancing the user experience. Furthermore, a single cut simultaneously yields a mattress body and modular strips with preset contours, effectively reducing waste and improving processing efficiency.
[0004] This invention is achieved through the following method: a double-panel self-locking mattress, comprising two independently set and combinable mattress bodies, each mattress body including a hard mattress and a soft mattress. A recessed, irregularly shaped self-locking area is provided in the center of the top surface of each mattress body. Several wide, parallel self-locking grooves are provided on the bottom surface of the irregularly shaped self-locking area. Modular strips with differentiated firmness can be selectively fastened to the self-locking grooves. The modular strips include hard strips and soft strips. The bottom of each modular strip has a fastening part that can be tightly locked into the corresponding self-locking groove. The hard and soft strips are freely matched and fixed to the self-locking grooves of each mattress body, and are flush with the top surface of the mattress body to form zones with differentiated firmness. The system incorporates hard and soft pads with varying degrees of hardness. When cutting to form hard pads, hard strips of the same hardness are simultaneously obtained; similarly, when cutting to form soft pads, soft strips of the same hardness are simultaneously obtained. The modular strips and pads are cut in a single operation to create a matching, locking structure. This allows for the creation of varying sizes and quantities of hard and soft partitions within the irregularly shaped self-locking areas of the hard and soft pads through the mixed use of hard and soft strips, meeting the diverse support needs of different users and enhancing the user experience. Furthermore, a single cut simultaneously yields pads and modular strips with preset contours, effectively reducing waste and improving processing efficiency.
[0005] Preferably, the rigid pad and rigid strip have the same hardness and are formed from the same material, and the soft strip and soft pad have the same hardness and are formed from the same material. The rigid strip is formed from waste material generated when cutting to form the irregular self-locking area of the rigid pad, and the soft strip is formed from waste material generated when cutting to form the irregular self-locking area of the soft pad. By cutting once, a pad and a module strip with the same hardness can be obtained simultaneously, and the module strip has a structure that can match and lock with the irregular self-locking area, which effectively simplifies the processing steps, reduces the number of cuts, and improves processing convenience.
[0006] Preferably, the number of rigid strips corresponds to the number of self-locking grooves on the rigid pad, and the number of soft strips corresponds to the number of self-locking grooves on the soft pad. Modular strips are formed simultaneously during the processing of the pad body. Waste material generated when cutting the pad body to form irregularly shaped self-locking areas can be used to form modular strips. Each modular strip has a fastening part formed when cutting the self-locking grooves. The number of modular strips that can be formed from the waste material is determined based on the number of fastening parts. This ensures that the number of modular strips corresponds to the number of self-locking grooves in the self-locking areas, ensuring that the processed rigid and soft strips can be installed into the respective locking grooves of the rigid and soft pads through a mixed-match method. This results in a multi-zone mattress that meets support requirements, avoids the generation of loose parts, prevents loss, and improves ease of use.
[0007] Preferably, the self-locking groove has a small opening and a large cavity, and the fastening part has the same cross-sectional profile as the self-locking groove. The fastening part is inserted into the self-locking groove and fits snugly. The fastening part and the self-locking groove are formed simultaneously through a single cut, which facilitates processing and ensures that their surface profiles are the same, thereby improving the reliability of locking by eliminating gaps.
[0008] Preferably, the modular strip includes a support portion exposed in the self-locking groove. Adjacent modular strips are fastened and locked to the corresponding self-locking groove via a fastening portion and are tightly fitted to the corresponding wall surface of the support portion, thereby ensuring a tight connection between the modular strips. The fastening and locking of the modular strips to the self-locking groove allows the support portions of adjacent modular strips to fit tightly together and form a flat support surface, effectively preventing mutual displacement or wobbling between adjacent modular strips.
[0009] Preferably, the top edges of the two side walls of the support portion are rounded, and the corresponding side walls of adjacent support portions are tightly fitted together at the top to form a movable space. The bottom of the corresponding walls of adjacent support portions are tightly fitted to improve positioning reliability. The rounded top edges provide deformation space for the support portion when the pad body bends, ensuring that the relative position of adjacent modules remains unchanged during the bending and resetting process of the pad body, and improving the fastening reliability between the module strip and the self-locking groove.
[0010] Preferably, the width of the support portion is the same as the distance between the centerlines of adjacent self-locking grooves, so that adjacent module strips can fit tightly against the corresponding sidewalls of the support portion after installation. When adjacent module strips are engaged with their corresponding self-locking grooves, the corresponding sidewalls of the support portion can fit tightly, effectively eliminating assembly gaps between adjacent module strips, improving the reliability of positioning and self-locking, and offsetting the horizontal force of the module strips through tight fitting, thereby ensuring that the module strips can transmit vertical force to the pad body and improving support comfort.
[0011] Preferably, the self-locking groove is provided through the width of the top surface of the pad. The self-locking groove includes an upward-facing exposed top slot and a side slot on the side wall of the pad. The edge of the top slot of the self-locking groove extends towards each other to form a locking part, and the bottom edge of the fastening part extends backward to form a locking protrusion that engages with the side of the self-locking groove cavity. The fastening part is inserted into the self-locking groove and is limited by the locking protrusion against the locking part. The self-locking groove includes side slots on both side walls of the pad and a top slot on the top surface of the pad. The side slots are used for assembling and disassembling the module strips, and the top slots are used to expose the support part. The module strips are assembled and disassembled through the side slots, which effectively reduces the deformation of the locking part and the locking protrusion. This prevents the locking part and the locking protrusion from reducing structural strength due to frequent compression deformation, thus affecting the fastening reliability, and also protects the locking part and the locking protrusion. The fastening part has locking protrusions extending in opposite directions on both sides. These protrusions abut against the locking part of the self-locking groove, preventing the fastening part from disengaging from the self-locking groove. The self-locking groove and the fastening part have the same cross-sectional profile, allowing the surface of the fastening part to fit tightly against the wall of the self-locking groove, thereby improving the reliability of the fastening by eliminating gaps.
[0012] A processing method for manufacturing the mattress involves preparing two raw material boards, including a hard board and a soft board. Each raw material board is cut once to simultaneously obtain a mattress body with irregularly shaped self-locking areas and self-locking grooves, as well as a semi-finished part formed from the cut portion. During the first cut, a snap-fit portion with the same cross-sectional profile as the self-locking groove is formed on the bottom surface of the semi-finished part. The semi-finished part is then further divided to form functional strips with the same firmness as the corresponding mattress body. The hard board is processed to form a hard mattress and hard strips, and the soft board is processed to form a soft mattress and soft strips. The hard and soft strips can be used alternately on either the soft or hard mattress to create zones with differentiated firmness on both types of mattresses. The two raw material boards have different hardness levels. The hard board is cut to form hard pads and hard strips, while the soft board is cut to form soft pads and soft strips. The waste generated during the processing of the irregular self-locking area of the pad is used as a semi-finished product for processing the modular strips. This process can simultaneously form the self-locking grooves in the irregular self-locking area and the fastening parts on the modular strips in a single cutting operation, effectively simplifying the processing steps, improving processing efficiency, and ensuring that the fastening parts can be precisely engaged with the self-locking grooves. Furthermore, the waste generated during the cutting of the irregular self-locking area can be cut a second time to form modular strips corresponding to the number of self-locking grooves, effectively improving the utilization efficiency of raw materials. By processing the hard board and the soft board separately, hard strips and soft strips with different hardness levels can be obtained. Through mixing and matching, different partition structures can be formed in the irregular self-locking areas of the hard pads and soft pads to meet the differentiated usage needs of different users.
[0013] Preferably, the hard pad and the soft pad are joined together to form a double pad for two people to use. The hard pad and the soft pad are joined left and right to ensure that the pad can independently support the user.
[0014] Preferably, during the secondary division, the semi-finished part is cut through the connecting area between adjacent fastening parts to form functional strips with the same contour. The semi-finished part contains modular strips corresponding to the number of self-locking grooves in the irregular self-locking area. Each independently set modular strip is obtained by secondary cutting of the semi-finished part. During the cutting, only the cutting operation of adjacent modules and the rounded edge cutting operation of the supporting part are required. The fastening parts formed simultaneously when cutting the self-locking grooves are used, eliminating the need for a special cutting operation to obtain the fastening parts, effectively simplifying the processing steps and improving the material utilization efficiency.
[0015] The beneficial effects of this invention are as follows: By setting up hard and soft pads with different hardness levels, a hard strip with the same hardness can be simultaneously obtained when cutting to form the hard pad, and a soft strip with the same hardness can be simultaneously obtained when cutting to form the soft pad. The modular strips and pad body achieve a matching and locking structure through a single cut. This allows for the formation of soft and hard partitions with different sizes and quantities by mixing and matching hard and soft strips within the irregularly shaped self-locking areas of the hard and soft pads, meeting the diverse support needs of different users and improving the user experience. Furthermore, a single cut can simultaneously obtain pad bodies and modular strips with preset contours, effectively reducing waste and improving processing efficiency. Attached Figure Description

[0017] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] Example 1: This embodiment provides a mattress.
[0019] like Figure 1 and 2 The mattress shown includes two independently set and combinable mattress bodies 1. Each mattress body 1 includes a firm mattress 12 and a soft mattress 13. The top surface of each mattress body 1 has a recessed, irregularly shaped self-locking area 3 in the center. The bottom surface of the irregularly shaped self-locking area 3 has several wide-through and parallel self-locking grooves 4. Modular strips 2 with different firmness can be selectively fastened to the self-locking grooves 4. Each modular strip 2 includes a firm strip 10 and a soft strip 11. The bottom of each modular strip 2 has a fastening part 6 that can be tightly locked into the corresponding self-locking groove 4. The firm strips 10 and soft strips 11 are freely matched and locked into the self-locking grooves 4 of each mattress body 1 and are flush with the top surface of the mattress body 1 to form a partition with different firmness. The system is equipped with hard pads 12 and soft pads 13 with different hardness levels. When the hard pad 12 is cut, a hard strip 10 with the same hardness can be obtained simultaneously. When the soft pad 13 is cut, a soft strip 11 with the same hardness can be obtained simultaneously. The module strip 2 and the pad body 1 are obtained through a single cut to obtain a matching and locking structure. This allows for the formation of soft and hard partitions with different sizes and quantities by mixing and matching hard strips 10 and soft strips 11 in the irregular self-locking area 3 of the hard pad 12 and soft pad 13, meeting the different support needs of different users and improving the user experience. Furthermore, the system can obtain the pad body 1 and module strip 2 with preset contours through a single cut, effectively reducing waste and improving processing efficiency.
[0020] In this embodiment, the mattress includes a hard mattress 12 and a soft mattress 13 of the same size and arranged symmetrically on the left and right. The mattress body 1 is joined together in the left and right directions to form a double mattress, and lying positions for different users are formed on the left and right sides of the top surface of the mattress.
[0021] In this embodiment, a recessed, irregularly shaped self-locking area 3 is provided in the center of the top surface of both the hard mattress 12 and the soft mattress 13. The mattress includes a modular strip 2 that can be installed in the irregularly shaped self-locking area 3. The modular strip 2 includes a soft strip 11 and a hard strip 10. The soft strip 11 and the hard strip 10 are mixed and matched to form multiple zones with different firmness in the irregularly shaped self-locking area 3, so that each lying position can meet the usage needs of the corresponding user.
[0022] In this embodiment, the hard pad 12 and the hard strip 10 have the same hardness and are formed from the same material. The soft strip 11 and the soft pad 13 have the same hardness and are formed from the same material. The number of hard strips 10 corresponds to the number of self-locking grooves 4 on the hard pad 12, and the number of soft strips 11 corresponds to the number of self-locking grooves 4 on the soft pad 13. The irregular self-locking areas 3 of the hard pad 12 and the soft pad 13 have the same number of self-locking grooves 4. The mattress is equipped with the same number of soft strips 11 and hard strips 10. The irregular self-locking areas 3 of the hard pad 12 and the soft pad 13 have the same number of self-locking grooves 4. The hard strips 10, soft strips 11, and the self-locking grooves 4 in each irregular self-locking area 3 have the same number, so that the configured hard strips 10 and soft strips 11 can be locked and fixed with the self-locking grooves 4 and effectively fill each irregular self-locking groove 4.
[0023] In this embodiment, the coverage area of the irregular self-locking area 3 of the pad 1 and the number of self-locking grooves 4 therein can be adjusted according to usage requirements, and all of these should be considered as specific implementations of this embodiment. There are at least six self-locking grooves 4 arranged closely in the middle of the top surface of the pad, so that the corresponding module strips 2 can be spliced to form at least two partitions. The self-locking grooves 4 within the irregular self-locking area 3 are continuous and equidistantly spaced, facilitating the insertion and assembly of the module strips 2. Preferably, the irregular self-locking area 3 is located in the middle section of the pad 1, and eleven self-locking grooves 4 are provided within the irregular self-locking area 3. This not only enhances the diversity of the partition structure but also improves processing efficiency by limiting the number of grooves, facilitating disassembly and assembly. All self-locking grooves 4 have the same cross-sectional profile, and the rigid strips 10 and soft strips 11 have the same cross-sectional profile, so that the rigid strips 10 and soft strips 11 can be used interchangeably by the user in the irregular self-locking area 3 of the rigid pad 12 or the soft pad 13, so that the pad body 1 can obtain a partition structure with differentiated hardness by setting the rigid strips 10 and soft strips 11 with differentiated hardness.
[0024] In this embodiment, taking the preferred solution described above as an example, the mattress includes a firm mattress 12, a soft mattress 13, eleven firm strips 10, and eleven soft strips 11, which can be used by two users. In use, firstly, each user selects either the firm mattress 12 or the soft mattress 13 according to their preference and assembles them to their corresponding lying position according to their sleeping habits. Then, each user selects a total of eleven firm strips 10 and soft strips 11 according to the support needs of their various body segments. Finally, each user mixes and assembles their assigned soft strips 11 and firm strips 10 (e.g., ...). Figure 6 As shown), the modular strips 2 are arranged within the irregularly shaped self-locking area 3 of the corresponding pad 1 to form a partitioned structure that meets the usage requirements. The total number of rigid strips 10 and the total number of flexible strips 11 are the same and fixed. Users can group the modular strips 2 according to their needs to ensure that the self-locking grooves 4 on each pad 1 can be filled by the modular strips 2 to form a flat supporting surface (as shown). Figure 3 (As shown).
[0025] In this embodiment, the irregular self-locking area 3 is provided in the middle of the top surface of the pad, which not only ensures that the irregular self-locking area 3 can correspond to the middle of the user's torso and ensures that the partition setting range meets the usage requirements, but also supports the user's head and feet by retaining the flat front and rear parts, effectively reducing the setting range of the irregular self-locking area 3. The modular strip 2 is flatly spliced with the front and rear of the top surface of the pad, reducing the amount of disassembly and assembly of the modular strip 2 and making it convenient for disassembly and assembly.
[0026] In this embodiment, the self-locking groove 4 is provided through the width of the top surface of the pad. The self-locking groove 4 includes a side groove exposed on the side edge of the pad and a top groove exposed on the top surface of the pad. The top groove cavity is small at the opening and large in the cavity (e.g., Figure 5 As shown), the module strip 2 includes a support portion 5 exposed in the self-locking groove 4 and a fastening portion 6 disposed below the support portion 5 (as shown). Figure 4 As shown, adjacent module strips 2 are fastened and locked to the corresponding self-locking grooves 4 via the fastening part 6 and are tightly fitted to the corresponding wall surface of the supporting part 5, so that the module strips 2 are tightly connected. The self-locking groove 4 includes an upward-facing exposed top groove and a side groove opened on the side wall of the pad. The fastening part 6 is inserted into the self-locking groove 4 through the side groove, so that the module strips 2 are exposed through the top groove and are joined together to form corresponding sections. During installation, the end of the module strip 2 is inserted through the side groove of the self-locking groove 4, so that the fastening part 6 slides along the self-locking groove 4 and fastens and locks, preventing the top groove of the self-locking groove 4 from being squeezed, deformed and damaged. After installation, the supporting part 5 is exposed through the top groove, and the top surfaces of adjacent module strips 2 and the area of the top surface of the pad that avoids the irregular self-locking area 3 can be joined to form a flat and continuous supporting surface.
[0027] In this embodiment, the width of the support portion 5 is the same as the distance between the centerlines of adjacent self-locking grooves 4, so that after the adjacent module strips 2 are installed, they fit tightly against the corresponding side walls of the support portion 5. When the module strip 2 is fastened to the corresponding self-locking groove 4, the corresponding side walls of the adjacent module strips 2 can fit tightly, effectively eliminating the assembly gap between them, which not only improves the connection reliability, but also prevents the module strips 2 from shaking under force, thereby ensuring the reliability of the support. In addition, the top edges of the two side walls of the support portion 5 are rounded, and the corresponding side walls of the adjacent support portions 5 fit tightly against each other and form an active space 7 at the top. This provides the active space 7 required for the deformation of the module strips 2 when the pad body 1 bends, thereby reducing the displacement of the module strips 2 by reducing the deformation, making it easier for the module strips 2 to reset, and also effectively reducing external forces in other directions except for vertical forces, thereby preventing the module strips 2 from detaching from the self-locking groove 4. Furthermore, the tight fit of the bottom of the corresponding side walls of the adjacent module strips 22 improves the reliability of the limiting.
[0028] In this embodiment, the fastening part 6 and the self-locking groove 4 have the same cross-sectional profile. The fastening part 6 is inserted into the self-locking groove 4 and locked in place. The top edge of the self-locking groove 4 extends towards each other to form a locking part 8. The bottom edge of the fastening part 6 extends backward to form a locking protrusion 9 that engages with the side of the self-locking groove 4. The fastening part 6 is inserted into the self-locking groove 4 and is limited by contact with the locking part 8 through the locking protrusion 9. The width of the top opening of the self-locking groove 4 is reduced by providing the locking part 8, and the locking part 8 and the locking protrusion 9 are in close contact, which prevents the fastening part 6 from vertically detaching from the self-locking groove 4 through the top opening, thereby ensuring that the top surfaces of adjacent module strips 2 can be connected smoothly.
[0029] In this embodiment, multiple irregularly shaped self-locking areas 3 can be provided on the pad body. Each irregularly shaped self-locking area 3 can be provided with different numbers of self-locking grooves 4 as needed to adjust the partition layout of the top surface of the pad body. All of these should be regarded as specific embodiments of the present invention.
[0030] In this embodiment, the top opening of the self-locking groove 4 is lower than the top surface of the pad. The module strip 2 is fastened and locked to the corresponding self-locking groove 4, so that the top surface of the module strip 2 is flush with the top surface of the pad. The self-locking groove 4 is located on the bottom surface of the irregular self-locking area 3. By reducing the height of the self-locking groove 4, installation space is provided for the module strip 2, thereby ensuring that the module strip 2 can be flush with the top surface of the pad, providing a flat and continuous support surface for the user.
[0031] Example 2: Compared to Embodiment 1, this embodiment provides a processing method.
[0032] like Figure 7 As shown, a processing method for processing the mattress includes the following steps: First, prepare two raw material boards, including a hard board and a soft board. The raw material boards are rectangular and have flat top and bottom surfaces. The hard board is cut from a harder raw material and the soft board is cut from a softer raw material. Secondly, each raw material plate is cut once to simultaneously obtain a pad 1 with an irregular self-locking area 3 and a self-locking groove 4, as well as a semi-finished part 14 formed by the cut-off portion (such as...). Figure 8 As shown), the pad 1 is cut to form an irregular self-locking area 3 with a preset number of self-locking grooves 4. At the same time, the waste material formed by the cutting forms a semi-finished part 14 that can be used to process and form a module strip 2. The bottom surface of the semi-finished part 14 forms a fastening part 6 with the same cross-sectional profile as the self-locking groove 4 during a single cut. Finally, the semi-finished part 14 is divided a second time to form functional strips with the same hardness as the corresponding pad 1 (such as...). Figure 9 As shown, the semi-finished part 14 formed by processing the hard plate is divided into a preset number of hard strips 10, and the semi-finished part 14 formed by processing the soft plate is divided into a preset number of soft strips 11.
[0033] The rigid pad 12 and the soft pad 13 are joined together to form a double pad for two people. When cutting the pad body 1 with the irregular self-locking area 3, the waste material generated during cutting can be used as a semi-finished part 14 for processing the module strip 2. This can effectively improve the utilization efficiency of raw materials by processing the rigid board and the soft board separately to obtain the hard strip 10 and the soft strip 11 that can be used together, thereby reducing the raw material cost by reducing waste. Furthermore, the waste material generated during the first cutting of the self-locking groove 4 can be used to form the fastening part 6 of the module strip 2, which can effectively reduce the difficulty of secondary division and thus reduce the processing cost.
[0034] In this embodiment, a rigid pad 12 and a rigid strip 10 are formed by processing a rigid board, and a soft pad 13 and a soft strip 11 are formed by processing a flexible board. The rigid strip 10 and the soft strip 11 can be used alternately on the soft pad 13 or the rigid pad 12 to form zones with different levels of hardness on the soft pad 13 and the rigid pad 12, respectively. Specifically, the rigid strip 10 and the soft strip 11 are arranged adjacently to form the boundaries of adjacent zones. The coverage area of a single zone is adjusted by continuously setting multiple modular strips 2 with the same hardness, thereby making the number of zones, the coverage area of each zone, and the hardness of each zone adjustable, providing users with diverse zone structures and providing comfortable support.
[0035] In this embodiment, during the secondary division, a through-cut is made along the connecting area between adjacent fastening parts 6 on the semi-finished part 14 to form functional strips with the same outline. This not only effectively utilizes the fastening parts 6 formed during the first cut, but also enables the independent division of the module strips 2 and the rounded corner cutting of the supporting part 5 during the secondary division, ensuring that each module strip 2 is located within the semi-finished part 14 without the need for additional raw materials.
[0036] The other structures and effects of the mattress described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
