Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mattress technology, specifically relating to a sponge support layer, a mattress core, and an electric mattress. Background Technology
[0002] Electric mattresses are generally similar to regular mattresses. However, electric mattresses require bending, while regular mattresses are relatively difficult to bend and their lifespan is affected by repeated bending. Specifically, firstly, the core of a regular mattress with a built-in spring core cannot be used on an electric mattress, as it is difficult to bend and is very easy to damage; secondly, mattresses with a single piece of support foam usually lack grooves, making it easy to tear the foam or create irreversible wrinkles when bent.
[0003] Therefore, it is necessary to improve existing mattresses to meet the specific usage requirements of electric mattresses. Furthermore, electric mattresses have both large and small bends during use, requiring appropriate design for areas with varying degrees of curvature. Summary of the Invention
[0004] This invention addresses the shortcomings of existing electric mattresses, which are not designed to accommodate bending requirements, leading to difficulties in bending or easy damage. It provides a foam support layer for electric mattresses that makes bending much easier. This invention also provides a mattress core and an electric mattress using this foam support layer.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sponge support layer for an electric mattress, wherein the sponge support layer comprises:
[0006] The support layer itself is rectangular in shape.
[0007] Among them, the support layer body has several sets of holes and slots that run through the width direction, one of which is the main hole and slot, which is directly opposite the waist and hip bend of the electric mattress.
[0008] The support layer body also has multiple sets of auxiliary holes and slots that extend through the width direction, and the cross-sectional dimensions of the auxiliary holes and slots are smaller than those of the main holes and slots.
[0009] The sponge support layer of this utility model has at least one set of main slots extending through the width of the electric mattress at the waist and hip bend. The main slots make it easier to bend the sponge support layer at the waist and hip bend, thus extending the service life of the sponge support layer. At the same time, the waist and hip bend is the part where bending is greatest, so the main slots at this part are of the greatest significance. The auxiliary slots have a similar function to the main slots. The cross-sectional dimensions of the auxiliary slots are smaller than those of the main slots, so that the bent sponge support layer can better fit the electric bed frame.
[0010] As an improvement, the support layer body has three sets of main slots, and the other two sets of main slots are located on both sides of the length direction of the knee bend of the electric mattress.
[0011] As an improvement, the three sets of main hole grooves include upper main hole grooves and lower main hole grooves distributed vertically.
[0012] As an improvement, the upper main hole groove includes an upper circular section and an upper open section; and / or,
[0013] The lower main hole groove includes a lower circular section and a lower open section.
[0014] As an improvement, the upper opening of the main channel at the lumbar bend is flared, wider on the outside and narrower on the inside; and / or,
[0015] The lower main opening at the lumbar-hip bend is flared at the bottom and wide at the top and bottom; and / or,
[0016] The upper openings of the main slots on both sides of the knee bend are of equal width; and / or,
[0017] The lower openings of the main grooves on both sides of the knee bend are wide at the bottom and wide at the top and bottom.
[0018] As an improvement, multiple sets of auxiliary slots are located at at least two locations: between the head end and the head bend, between the head bend and the middle bend, between the middle bend and the tail bend, and between the tail bend and the tail end.
[0019] As an improvement, the cross-sectional dimensions of each auxiliary hole and groove are smaller than those of the hole and groove.
[0020] As an improvement, each set of auxiliary holes and slots includes upper auxiliary holes and slots distributed vertically. The upper auxiliary holes and slots include an upper auxiliary circular section and an upper auxiliary open section, and are flared in shape with the outer side being larger than the inner side. The lower auxiliary holes and slots include a lower auxiliary circular section and a lower auxiliary open section.
[0021] As an improvement, several upper auxiliary opening sections adjacent to the main opening groove at the waist-hip bend are flared outwards, wider at the outside and narrower at the inside, while other upper auxiliary opening sections are of equal width; and / or,
[0022] The lower auxiliary holes and grooves are all flared, with the outer opening being larger than the inner opening.
[0023] Bed core, the bed core comprising:
[0024] Top comfort layer;
[0025] Sponge support layer;
[0026] Bottom comfort layer;
[0027] The sponge support layer is the aforementioned sponge support layer.
[0028] As an improvement to the mattress core, the top comfort layer and the bottom comfort layer have different firmness; and / or,
[0029] The thickness of the foam support layer is greater than that of the top comfort layer and the bottom comfort layer; and / or,
[0030] The top comfort layer and / or bottom comfort layer are in contact with the sponge support layer through a smooth fabric.
[0031] Electric mattress, the electric mattress comprising:
[0032] Bed core;
[0033] Outer fabric cover;
[0034] The bed core is the aforementioned bed core.
[0035] As an improvement on electric mattresses, the outer cover consists of two parts, upper and lower, connected by a zipper.
[0036] The beneficial effects of the sponge support layer of this utility model are as follows: its cuboid support layer body has at least one set of main holes and grooves that extend through the width direction at the waist and hip bend of the electric mattress. The setting of the main holes and grooves makes it easier for the sponge support layer to bend at the waist and hip bend, thus extending the service life of the sponge support layer. At the same time, the waist and hip bend is the part with the greatest bending, so the setting of the main holes and grooves at this part is of the greatest significance. The auxiliary holes and grooves have a similar function to the main holes and grooves. The cross-sectional dimensions of the auxiliary holes and grooves are smaller than those of the main holes and grooves, so that the bent sponge support layer can better fit the electric bed frame.
[0037] The bed core and electric mattress of this utility model adopt the sponge support layer of this utility model and have all the beneficial effects of the sponge support layer of this utility model. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be explained and described below. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.
[0049] See Figures 1 to 7 The sponge support layer of this utility model embodiment is used in an electric mattress, and the sponge support layer includes:
[0050] The support layer itself is rectangular in shape.
[0051] Among them, the support layer body has several sets of holes and slots that run through the width direction, one of which is the main hole and slot, which is directly opposite the waist and hip bend of the electric mattress.
[0052] The support layer body also has multiple sets of auxiliary holes and slots that extend through the width direction, and the cross-sectional dimensions of the auxiliary holes and slots are smaller than those of the main holes and slots.
[0053] Existing electric mattresses mostly lack multiple sets of slots running through their core foam support layer, making bending difficult. Furthermore, the upper surface is compressed and the lower surface stretched at the hip and lumbar bends, and the upper surface is stretched and the lower surface compressed at the knee bends, leading to fatigue after a period of use and a shorter lifespan. The foam support layer of this invention features at least one set of main slots running through the width of the electric mattress at the hip and lumbar bends. These main slots facilitate bending at these points, extending the lifespan of the foam support layer. Since the hip and lumbar bends are the areas of greatest bending, the main slots at this location are most significant. Auxiliary slots serve a similar function to the main slots; however, the cross-sectional dimensions of the auxiliary slots are smaller than those of the main slots, allowing the bent foam support layer to better conform to the electric bed frame.
[0054] Example 1
[0055] See Figures 1 to 6 The electric mattress of this utility model embodiment 1 includes a mattress core 02 and an outer fabric cover 01. The mattress core 02 includes a top comfort layer 1, a sponge support layer 2 and a bottom comfort layer 3. The sponge support layer 2 includes a cuboid support layer body 21. The support layer body 21 has three sets of main holes that run through the width direction. One set of main holes is directly opposite the waist and hip bend of the electric bed frame (which is also an electric mattress), and the other two sets of main holes correspond to the two sides of the knee bend in the length direction.
[0056] In this embodiment, the three sets of main hole grooves include an upper main hole groove 22 and a lower main hole groove 23 distributed vertically.
[0057] In this embodiment, the upper main hole groove 22 includes an upper circular section 221 and an upper open section 222. The upper open section 222 is located at the outer end of the upper circular section 221.
[0058] In this embodiment, the lower main hole groove 23 includes a lower circular section 231 and a lower opening section 232. The lower opening section 232 is located at the outer end of the lower circular section 231.
[0059] In this embodiment, the upper opening section 222 of the upper main groove 22 at the waist-hip bend is flared outwards, wider at the outside and narrower at the inside. Since the waist-hip bend is subject to compression, designing the upper opening section 222 at this location as flared outwards makes it flatter after compression and less prone to protrusion.
[0060] In this embodiment, the upper opening sections 222 of the upper main hole groove 22 on both sides of the knee bend along the length direction are of equal width. In other embodiments, the upper opening sections 222 of the upper main hole groove 22 on both sides of the knee bend along the length direction may also be constricted in shape, with the outer opening being smaller and the inner opening being larger.
[0061] In this embodiment, the three lower main hole grooves 23 are all flared at the bottom and top, making it easy for the sponge support layer 2 to bend.
[0062] In this embodiment, the cross-sectional dimensions of the auxiliary slots are all smaller than those of the main slots.
[0063] In this embodiment, each set of auxiliary holes and slots includes an upper auxiliary hole and slot 24 and a lower auxiliary hole and slot 25 distributed vertically. The upper auxiliary hole and slot 24 includes an upper auxiliary circular segment 241 and an upper auxiliary open segment 242, and the lower auxiliary hole and slot 25 includes a lower auxiliary circular segment 251 and a lower auxiliary open segment 252.
[0064] In this embodiment, in the upper auxiliary slot 24, several upper auxiliary opening segments 242 adjacent to the upper main slot 22 at the waist-hip bend are flared outwards, wider at the outside and narrower at the inside, while the other upper auxiliary opening segments 242 are of equal width. Specifically, as shown... Figure 4As shown, the upper auxiliary opening section 242, which is flared outwards and narrower inwards, includes several (one) on the head side and several (four) on the foot side of the upper main hole groove 22.
[0065] In this embodiment, the thickness of the sponge support layer 2 is greater than that of the top comfort layer 1 and the bottom comfort layer 3.
[0066] In this embodiment, the hardness of both the top comfort layer 1 and the bottom comfort layer 3 is less than that of the sponge support layer 2.
[0067] In this embodiment, the top comfort layer 1 and / or the bottom comfort layer 3 are in contact with the sponge support layer 2 via a smooth fabric. Specifically, a smooth fabric may be applied (e.g., by adhesive) to the top comfort layer 1 and / or the bottom comfort layer 3, or the top comfort layer 1 and / or the bottom comfort layer 3 may be included in a separate inner sleeve made of a low-friction fabric, or the side of the top comfort layer 1 and / or the bottom comfort layer 3 closest to the sponge support layer 2 may have an egg-shaped cut.
[0068] In this embodiment, the outer fabric cover 01 includes upper and lower parts connected by a zipper 03, facilitating cleaning and replacement. The zipper 03 is located in the middle of the thickness direction of the electric mattress.
[0069] In this embodiment, see Figure 4 Typically, electric bed frames have three points of movement, corresponding to the lumbar-hip bend, the middle bend, and the knee bend. The lumbar-hip bend has the largest bending amplitude (or angle), therefore the dimensions of the upper main slot 22 and lower main slot 23 at this point are larger than the auxiliary slots. The upper surface at the lumbar-hip bend is compressed, so the upper opening section 222 of the upper main slot 22 at this point is flared, wider on the outside and narrower on the inside. The upper auxiliary opening sections 242 of the adjacent auxiliary slots 24 are also flared, wider on the outside and narrower on the inside. The lower main slot 22 at this point is also designed to be flared, wider on the outside and narrower on the inside, further reducing the bending thickness at this point and facilitating bending. The upper surface at the knee bend is stretched, therefore the upper opening sections 222 of the two upper main slots 22 at the knee bend are of equal width. The lower surface at the knee bend is compressed, therefore the lower opening sections 232 of the two lower main slots 23 at the knee bend are flared, wider on the outside and narrower on the inside. Except for the upper auxiliary opening sections 242 of the upper auxiliary slots 24 adjacent to the waist-hip bend, which are flared outwards and narrowed inwards, the upper auxiliary opening sections 242 of the other upper auxiliary slots 24 are all of equal width to reduce surface gaps after bending.
[0070] The beneficial effects of the electric mattress in Embodiment 1 of this utility model are as follows: The cuboid-shaped support layer body 21 of the foam support layer 2 of the bed core 02 has multiple sets of main slots running through the width direction at the corresponding bends. The main slots make the thickness of the foam support layer 2 at the bends smaller, making the bends easier and extending the service life of the foam support layer 2. The circular section of the main slots avoids stress concentration and prevents tearing. The foam support layer 2 of the bed core 02 also has multiple sets of auxiliary slots running through the width direction, further facilitating the bends of the mattress. The main and auxiliary slots, with the cross-sectional dimensions of the auxiliary slots being smaller than those of the main slots, allow the bent foam support layer to better conform to the electric bed frame. The friction between the top comfort layer 1 and / or the bottom comfort layer 3 and the foam support layer 2 is small, reducing the restriction on the foam support layer 2 during deformation. The outer cover 01 is divided into upper and lower parts connected by a zipper, facilitating cleaning and replacement.
[0071] Example 2
[0072] See Figure 7 In this embodiment, to provide different firmness when the mattress is used on each side, the top comfort layer 1 and the bottom comfort layer 3 have different firmnesses. The top comfort layer 1 and the bottom comfort layer 3 are respectively set to a softer and a moderately firm sponge, so that the two sides of the mattress have different sleeping experiences.
[0073] In this embodiment, the sponge support layer 2 is symmetrical vertically. The upper openings 222 of all upper main slots 22 are flared, wider at the outside and narrower at the inside; the lower openings 232 of all lower main slots 23 are also flared, wider at the outside and narrower at the inside. Similarly, the upper auxiliary openings 242 of all upper auxiliary slots 24 are flared, wider at the outside and narrower at the inside; and the lower auxiliary openings 252 of all lower auxiliary slots 25 are flared, wider at the outside and narrower at the inside. This symmetrical design allows the mattress to be easily bent regardless of whether it is used from the front or back. The flared shapes are also isosceles trapezoidal.
[0074] In other embodiments, the upper opening section 222 of the upper main hole groove 22 at the waist-hip bend can be flared outwards, wider at the outside and narrower at the inside, while the upper opening sections 222 of the upper main hole groove 22 at the other two locations can be of equal width. The opening section can be designed as flared, narrowed, or of equal width as needed.
[0075] This utility model embodiment also discloses the aforementioned bed core 02, which includes a top comfort layer 1, a sponge support layer 2, and a bottom comfort layer 3. The sponge support layer 2 includes a cuboid support layer body 21, which has several sets of holes and slots extending through the width direction. The several sets of holes and slots correspond to at least one of the head bend, middle bend, and tail bend of the electric mattress.
[0076] This utility model embodiment also discloses the aforementioned sponge support layer 2, which includes a cuboid support layer body 21. The support layer body 21 has several sets of holes and slots extending through the width direction, and the several sets of holes and slots correspond to at least one of the head bend, middle bend, and tail bend of the electric mattress.
[0077] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
