Description

Technical Field

[0001] This utility model belongs to the field of mattress technology, specifically relating to a folding mattress adapted to an electric bed and an electric bed using the same. Background Technology

[0002] Existing electric folding mattresses have internal materials that need to be adapted to bending, but lack strong support materials at the edges. This results in a lack of support points when moving the mattress. Furthermore, because they need to be adapted to the bending of electric beds, holes need to be made in the edge support foam, which may lead to poor edge support and a risk of the mattress edges collapsing.

[0003] Generally, pocket spring mattress cores require a layer of non-woven fabric to be glued to both the top and bottom surfaces; this gluing process is called lamination. However, to accommodate the bending of electric mattresses, the lamination process is often omitted on the reverse side of the mattress core. Therefore, when the mattress core is rolled up, the front and back sides may be different sizes. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a folding mattress adapted to an electric bed and an electric bed using the same. The mattress core has a composite elastic fabric on its lower surface, and a folding section is provided on the edge protection structure. While ensuring the edge support of the mattress, it allows the mattress to better cooperate with the electric bed to fold, and keeps the bottom of the mattress in close contact with the electric bed during the folding process.

[0005] This utility model provides a folding mattress adapted to an electric bed, including a core, an edge protection structure disposed around the core, and an outer cover covering the core and the edge protection structure. The core is characterized in that it is composed of a plurality of pocket springs. The lower surface of the core is covered with a composite elastic fabric, which is elastic along the length of the core. The edge protection structure, which is arranged along the length of the core, has multiple bends corresponding to the bends of the electric bed.

[0006] Compared to conventional composite nonwoven fabrics, composite elastic fabrics offer superior stretchability, allowing the fabric to deform synchronously with the mattress core when the electric mattress is bent. The composite elastic fabric covering the lower surface of the core provides excellent stretchability, elasticity, and tensile strength, enabling the mattress to adapt to roll-up packaging and the bending requirements of electric mattresses. Furthermore, the mattress effectively returns to its original shape after rolling and bending. Simultaneously, the bends in the edge protection structure ensure both the mattress's ability to flex with the electric mattress and adequate edge support.

[0007] In a preferred embodiment, the upper surface of the core is covered with a composite elastic fabric.

[0008] Composite elastic fabric is applied to both the upper and lower surfaces of the core. This effectively reduces wrinkles and stacking of the material on the upper surface of the core when it is rolled up for packaging or bent in conjunction with an electric bed. At the same time, the composite elastic fabric on the upper surface can use its own elasticity to tighten the upper end of the spring in the core to a certain extent, thereby constraining the position of the spring.

[0009] In a preferred embodiment, each of the bending portions includes a plurality of opening slots disposed on the upper and lower surfaces of the edge protection structure, and the spacing between each opening slot is equal.

[0010] The slotted openings provide bending and deformation space for the edge protection structure, preventing tearing when the mattress is bent to fit an electric mattress. The equal spacing between the slots at each bend ensures that stress is evenly distributed across all slots during bending, preventing stress concentration in any single slot from causing structural deformation.

[0011] In a preferred embodiment, the cross-section of the opening groove is a V-shape with the bottom connected to a circle, wherein the V-shaped opening is disposed on the surface of the edge protection structure.

[0012] The V-shaped opening of the groove allows the edge protection structure to be bent in conjunction with the electric bed, and the circular structure at the bottom eliminates stress concentration points at the bottom of the V-shaped groove, preventing tearing at the bottom of the groove after long-term bending, thereby effectively improving the durability of the edge protection structure.

[0013] In a preferred embodiment, the V-shaped opening width of the opening groove is 1cm to 5cm, and the depth of the opening groove is less than 1 / 3 of the height of the edge protection structure.

[0014] The width of the V-shaped opening of the groove is limited to ensure sufficient space for bending deformation while preventing the opening from being too wide, which would result in insufficient support area for the edge support structure and thus affect the support of the mattress edge. The depth of the groove is also limited to prevent the groove from being too deep and affecting the support performance of the edge support structure.

[0015] In a preferred embodiment, the number of opening slots provided on the lower surface of the edge protection structure is greater than the number of opening slots provided on the upper surface of the edge protection structure.

[0016] When bending, the lower surface is mainly subjected to expansion force. More openings on the lower surface can provide more deformation space for the expansion force, preventing the edge protection structure from being damaged by tensile force due to excessive expansion force. The upper surface is mainly subjected to contraction force. While meeting the deformation requirements of the upper surface contraction force, in order to maintain the support performance of the edge protection structure, the number of openings on the upper surface should be reduced to prevent the support performance of the edge protection structure from decreasing due to too many openings on the upper surface.

[0017] In a preferred embodiment, the edge protection structure is made of high-density, high-hardness sponge, wherein the density of the sponge is greater than or equal to 30 kg / m3, and the hardness of the sponge is obtained by indentation test, with an indentation hardness greater than or equal to 200 N.

[0018] The edge support structure enhances the support strength of the mattress edge, preventing significant sagging when the body leans against or sits on the edge. At the same time, the high-density, high-hardness foam has stronger tear resistance and can be combined with the grooved openings to allow for long-term bending without easily breaking, thus extending the service life of the edge support structure.

[0019] In a preferred embodiment, padding layers are provided between the upper part of the core and the outer sleeve, and between the lower part of the core and the outer sleeve; the padding layers are made of sponge with high tensile and high resilience properties; wherein the sponge has a minimum resilience greater than 50%, a minimum tensile strength greater than or equal to 80 kPa, and a minimum elongation at break of 100%.

[0020] The padding layer further enhances the comfort of the mattress. Its high tensile and high resilience properties allow it to bend with electric beds and be packaged in mattress rolls, while also maintaining the stability of the overall mattress structure.

[0021] In a preferred embodiment, each of the bag springs includes a bag body and a spring inserted into the bag body. The spring is in the shape of a drum, which is wider in the middle and narrower at both ends. The inner cavity shape of the bag body matches the shape of the spring.

[0022] Compared to traditional cylindrical springs, drum-shaped springs have better bending adaptability. The narrow sections at both ends of the drum-shaped springs provide more deformation space, which can better adapt to the bending of electric beds. It can also reduce the risk of two adjacent independent springs getting stuck in each other through the spring pocket, and reduce the noise generated by mattress deformation when bending.

[0023] On the other hand, this utility model also provides an electric bed, including a bendable and adjustable electric bed frame, on which the aforementioned bendable mattress adapted to the electric bed is provided.

[0024] When the electric bed frame is bent and adjusted, the mattress also bends. Using the above-mentioned bendable mattress that is compatible with electric beds can better cooperate with the bending of the electric bed. When bending, the mattress and the electric bed frame fit well together and there is no suspension, which effectively improves the user experience.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared to conventional composite nonwoven fabrics, composite elastic fabrics offer superior extensibility. When the mattress is bent in an electric bed, the fabric deforms synchronously with the core. Therefore, incorporating composite elastic fabric on the lower surface of the core provides excellent extensibility, elasticity, and tensile properties, allowing the mattress to adapt to roll-up packaging and the bending requirements of electric beds. Furthermore, the mattress retains its original shape well after rolling and bending. Simultaneously, the bends in the edge protection structure ensure both the mattress's ability to flex with the electric bed and adequate edge support.

[0026] A further optimization solution involves setting composite elastic fabric on both the upper and lower surfaces of the core. This effectively reduces wrinkles and stacking of the material on the upper surface of the core during roll packaging and bending with an electric bed. At the same time, the composite elastic fabric on the upper surface can use its own elasticity to tighten the upper end of the spring in the core to a certain extent, thereby constraining the position of the spring.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1: like Figure 1 As shown, this embodiment provides a folding mattress adapted to an electric bed, including a core 1, an edge protection structure 2 disposed around the core 1, and an outer cover 3 covering the core 1 and the edge protection structure 2.

[0031] like Figure 2 and Figure 5 As shown, the core 1 is composed of several pocket springs 101, each pocket spring 101 including a bag body and a spring 1011 inserted into the bag body. The spring 1011 is in the shape of a drum, which is wider in the middle and narrower at both ends. The inner cavity shape of the bag body matches the shape of the spring 1011 to accurately fix the spring 1011 in the bag body and prevent the spring 1011 from shifting during use or transportation.

[0032] Compared to traditional cylindrical springs, drum-shaped springs offer better flexibility in bending. The openings on the top and bottom sides of adjacent drum-shaped springs provide greater deformation space for mattress bending, making them better suited for electric mattresses. They also reduce the risk of two adjacent independent springs getting stuck on each other through the spring pockets, and reduce the noise generated by mattress deformation during bending.

[0033] During production, several springs 1011 are inserted into a bag made of non-woven fabric. The length of the bag is the same as the length of the core 1, and the height of the bag is the same as the height of the springs 1011. The non-woven fabric between two adjacent springs 1011 is fused together using a welding knife to form a bag-packed spring string. Then, several bag-packed spring strings are connected together according to the width of the core 1 to form the core 1.

[0034] Furthermore, such as Figure 5 and Figure 6 As shown, in order to better adapt the core 1 to the bending of the electric bed, an opening structure 103 is provided between two adjacent pocket springs 101 in the pocket spring string. The structure of the pocket spring string without the opening structure 103 is as follows. Figure 7 As shown.

[0035] The opening structure 103 is disposed between the lower ends and / or upper ends of two adjacent pocket springs 101. In this embodiment, it is preferable that the opening structure 103 is disposed between both the upper and lower ends, and the ratio of the height of the opening structure 103 to the height of the bed core is between 10% and 40%.

[0036] The opening structure 103 includes linear and non-linear openings. Specifically, a linear opening is formed by cutting inward from the outer edge of the connecting fabric between two adjacent pocket springs 101. The structure of the linear opening is as follows: Figure 5As shown; a non-linear opening is formed by partially removing material from the outer edge of the connecting fabric between two adjacent pocket springs 101, thus creating a non-linear opening structure as follows. Figure 6 As shown. For the specific structure of the opening structure 103, please refer to Chinese patent document with application number 2023234899176.

[0037] To accommodate the bending of the electric bed, a composite elastic fabric 4 is applied to the lower surface of the core 1. The composite elastic fabric 4 is elastic along the length of the core 1. Since the core 1 only needs to accommodate bending and rolling in the length direction, the elasticity of the composite elastic fabric 4 in the width direction is not required.

[0038] Compared to conventional composite nonwoven fabrics, composite elastic fabrics have better extensibility, allowing the fabric to deform synchronously with the core when the electric mattress is bent. Therefore, covering the lower surface of the core with composite elastic fabric gives the lower surface of the core good extensibility, elasticity, and tensile properties, enabling the mattress to adapt to the needs of roll packaging and bending in electric mattresses, and the mattress can also well restore its original shape after being rolled and bent.

[0039] A further optimization involves covering both the upper and lower surfaces of the core with a composite elastic fabric. This effectively reduces wrinkles and stacking of the material on the upper surface of the core during roll packaging and bending with an electric bed. Simultaneously, the composite elastic fabric on the upper surface can use its own elasticity to tighten the upper end of the spring inside the core to a certain extent, thus constraining the spring's position. The composite elastic fabric 4 is adhered to the core 1 via an adhesive bonding structure. For details on the adhesive bonding method, please refer to Chinese patent document application number 2024229828870.

[0040] To ensure the support of the mattress edge, a protective edge structure 2 is provided around the core 1. In order to enable the protective edge structure 2 to also bend with the electric bed, multiple bending parts 201 corresponding to the bending points of the electric bed are provided on the protective edge structure 2 which is set along the length of the core 1.

[0041] like Figure 4 As shown, the bending section 201 has three regions: A, B, and C. Region A corresponds to the lower leg, region B corresponds to the thigh, and region C corresponds to the head, back, and waist. To reduce the bending stress between regions B and C, a buffer zone D that does not bend is added between B and C.

[0042] like Figure 3As shown, in order to provide space for bending deformation of each bending part 201, each bending part 201 includes multiple opening slots 202 provided on the upper and lower surfaces of the edge protection structure 2, and the spacing between each opening slot 202 is equal so that when the mattress is bent, the stress of each bending part 201 can be evenly distributed to each opening slot 202, avoiding local stress concentration in a certain opening slot 202 that could lead to structural deformation.

[0043] like Figure 3 As shown, in order to prevent stress concentration at the opening groove 202, which could lead to tearing of the groove bottom after long-term bending and thus affect the durability of the edge protection structure 2, the cross-section of the opening groove 202 is a V-shape with the bottom connected to a circle, wherein the V-shaped opening is set on the surface of the edge protection structure 2.

[0044] Furthermore, in order to ensure sufficient bending and deformation space while avoiding insufficient support area of ​​the edge support structure 2 due to excessively wide opening of the opening groove 202, thereby affecting the support of the mattress edge, the V-shaped opening width of the opening groove 202 is 1cm~5cm; in order to prevent the edge support structure 2 from being affected by excessively deep opening groove 202, the depth of the opening groove 202 should be less than 1 / 3 of the height of the edge support structure 2.

[0045] When the mattress is bent, the lower surface primarily experiences expansion force, while the upper surface primarily experiences contraction force. To meet the deformation requirements of the upper surface under contraction force, and to maintain the support performance of the edge support structure 2, the number of openings 202 on the upper surface should be reduced to prevent a decrease in support due to an excessive number of openings 202. The lower surface, however, requires more openings 202 to provide sufficient deformation space for expansion force, preventing tensile damage to the edge support structure 2 due to excessive expansion force. Therefore, at the same bend 201, the number of openings 202 on the lower surface of the edge support structure 2 is greater than the number on the upper surface.

[0046] Furthermore, in order to improve the support strength of the edge protection structure for the edge of the mattress, prevent significant collapse when the human body leans against or sits on the edge of the mattress, and extend the service life of the edge protection structure 2, the edge protection structure 2 is made of high-density, high-hardness sponge, wherein the density of the sponge is greater than or equal to 30kg / m3, and the hardness of the sponge is obtained by indentation test, with an indentation hardness greater than or equal to 200N.

[0047] To further enhance mattress comfort and maintain the stability of the overall mattress structure, padding layers 5 are provided between the top of the core 1 and the outer cover 3, and between the bottom of the core 1 and the outer cover 3. To accommodate the bending of the electric bed and the mattress roll packaging, padding layers 5 are made of foam with high tensile and high resilience properties; specifically, the foam has a minimum resilience rate greater than 50%, a minimum tensile strength greater than or equal to 80 kPa, and a minimum elongation at break of 100%.

[0048] In summary, the folding mattress adapted to electric beds provided in this embodiment can ensure the edge support performance of the mattress while being compatible with the bending and rolling packaging of electric beds. Furthermore, the mattress can still well restore its original shape after long-term bending use and after unpacking.

[0049] Example 2: This embodiment provides an electric bed, including a bendable and adjustable electric bed frame, on which a bendable mattress adapted to the electric bed as described in Embodiment 1 is provided.

[0050] When the electric bed frame is bent and adjusted, the mattress bends along with it. Using the bendable mattress provided in Example 1, which is compatible with the electric bed, the mattress edge support performance can be guaranteed while better cooperating with the bending of the electric bed. Moreover, when bending, the mattress and the electric bed frame fit well together and there is no suspension, which effectively improves the user experience.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
