Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sponge mattresses, in particular to a sponge mattress adapted to an electric bed. Background Art
[0002] With the development of social economy and the improvement of people's living standards, people have higher and higher requirements for sleeping comfort, and the demand for electric beds has also risen. Electric beds can not only meet the needs of lying down sleeping, but also bend at various angles to help patients sit up and lie down, and adjust to help improve back and lumbar problems, help quickly enter deep sleep, and help improve respiratory diseases. In order to improve the comfort of electric beds, electric beds are generally equipped with mattresses. Sponge mattresses have good elasticity, can adapt to the shape of the human body, and make people sleep more comfortably. At the same time, sponge mattresses also have good air permeability. Compared with spring mattresses, sponge mattresses have no springs and will not squeak when used, making sleep quieter. Therefore, sponge mattresses are favored by some consumers.
[0003] When the electric bed frame is bent, the cotton mattress will also bend with it. However, the mattress is not fixed to the bed frame. In addition, due to the structure and hardness of the mattress itself, the mattress cannot fit completely with the bed frame when the bed frame is bent, resulting in the mattress hanging in the air and the piercing point being displaced. In addition, the inner side of the bent part of the mattress will be squeezed to a certain extent, and the outer side of the bent part will be stretched to a certain extent, generating stress that affects the service life of the mattress.

[0006] Preferably, in order to reduce the risk of breakage of the mattress sponge material after multiple bending, thereby increasing the service life of the mattress, the tops of the bending notch 2, the bending notch 3 and the bending notch 1 are all arc-shaped.
[0007] Preferably, in order to improve the comfort of the mattress, the comfort layer is made of slow-rebound sponge.

[0010] Preferably, in order for the bottom of the buffer layer to fit more closely to the bed frame when the bed frame is deformed, cutting notches are respectively provided at the bottom of the buffer layer.

[0019] The utility model is further described below in conjunction with the accompanying drawings:
[0020] like Figure 1-6 As shown, the present embodiment provides a sponge mattress adapted to an electric bed, comprising a buffer layer 2, a support layer 3 is installed on the top outer wall of the buffer layer 2, a comfort layer 1 is installed on the top outer wall of the support layer 3, a bending slot 1 4, a bending slot 2 5 and a bending slot 3 6 are respectively provided on the buffer layer 2, the bending slot 3 6 is located on the right side of the bending slot 2 5, and the bending slot 1 4 is located on the right side of the bending slot 3 6. There are three areas where the electric bed frame will bend when in use, which are the first bending point, the second bending point and the third bending point from left to right, and the first bending point is set from the back to the buttocks, the second bending point from the buttocks to the thighs, and the third bending point from the thighs to the calves (i.e., the knees). At the first bending point and the second bending point, one of the plates of the electric bed frame is tilted upward. At this time, the corresponding area of the buffer layer 2 is in a stretched state, and the spacing between the corresponding bending slot 2 5 and the bending slot 3 6 will be enlarged, as shown in FIG. Figure 4 As shown, the buffer layer 2 can adapt to the tensile deformation well, so that the mattress can fit the electric bed frame at the first bend and the second bend. When one of the plates of the electric bed frame is tilted downward at the third bend, the corresponding area of the buffer layer 2 is squeezed, and the corresponding bending notch 4 is reduced in spacing, as shown in FIG. Figure 5 As shown, the mattress can better adapt to extrusion deformation, and the mattress can reduce the impact of extrusion and stretching on the mattress when the mattress is bent, so that the mattress has a longer life. At the same time, the mattress fits the electric bed frame more closely at the bending part, and can effectively reduce the gap between the mattress and the bed frame, thereby increasing the fit between the mattress and the bed frame. Because the larger the contact area between the mattress and the electric bed frame, the stronger the friction, the mattress has strong stability and can effectively reduce displacement. The shape of the bending groove 4 is not limited, and other shapes of grooving can also be achieved.
[0021] The comfort layer 1 is connected to the support layer 3 by glue, and the support layer 3 is connected to the buffer layer 2 by glue, and the comfort layer 1, the support layer 3 and the buffer layer 2 can be effectively connected by glue. Grooves 7 are provided on the comfort layer 1, the buffer layer 2 and the support layer 3, and the grooves 7 are distributed at the head and the bed of the mattress. The number of grooves 7 provided at each part is 10-15. The grooves 7 make the mattress at this part easier to bend, which helps the sponge mattress to fit the electric bed frame better.
[0022] The tops of the bending slot 2 5, the bending slot 3 6 and the bending slot 1 4 are all arc-shaped. The arc-shaped treatment can effectively reduce the stretching and expansion forces on the mattress structure during bending, reduce the risk of breakage of the mattress sponge material after multiple bending of the electric bed, ensure the normal use of the electric bed, and extend the service life of the mattress.
[0023] The material of the comfort layer 1 is slow-rebound sponge, which is commonly known as memory foam. It is a polyurethane polymer with an open cell structure. The material has significant viscoelastic properties, reflects very soft material properties, and has strong impact energy absorption capacity. The viscoelastic property means that the product sinks under pressure, but does not show strong rebound force (such as clay sinking under pressure). When the pressure is removed, the product will gradually return to its original shape. Therefore, the comfort layer 1 can effectively improve the comfort of the mattress.
[0024] The cushioning layer 2 and the supporting layer 3 are both made of dynamic support cotton, which is located between the softer comfort layer sponge and the harder support layer sponge, so the cushioning layer 2 and the supporting layer 3 can play a role in easing the transition. The comfort layer 1, the cushioning layer 2 and the supporting layer 3 are respectively provided with two grooves 8, which are located in the middle of the mattress and are 2-3 in number. The deformation in the middle of the mattress is small, so there is no need to provide too many grooves 8. A small number of grooves 8 can ensure that the mattress in that part can produce micro-deformation better and ensure the support of the mattress in that part.
[0025] The bottom of the buffer layer 2 is respectively provided with cutting notches 9 , which can make the buffer layer 2 fit the bed frame more closely when the buffer layer 2 is slightly deformed.
[0026] When the utility model is in use, the bed frame is bent from left to right, and there are first bends, second bends and third bends in sequence. At the first bend and the second bend of the electric bed frame, one of the plates is tilted upward, that is, the effect on the corresponding area of the buffer layer 2 is stretching, and the corresponding spacing between the bending notch 2 5 and the bending notch 3 6 is enlarged, such as Figure 4 As shown, the buffer layer 2 can better adapt to the tensile deformation, so that the mattress fits the electric bed frame more closely at the first bend and the second bend, effectively reducing the gap. At the third bend, one of the plates of the electric bed frame is tilted downward, that is, the corresponding area of the buffer layer 2 is squeezed, and the corresponding bending notch 4 spacing is reduced. Figure 5As shown, the mattress fits the electric bed frame more closely at the bend, effectively reducing the gap, reducing the overhang, and increasing the fit between the mattress and the bed frame. The larger the contact area between the mattress and the electric bed frame, the stronger the friction between the two. Therefore, the mattress is more stable, can reduce displacement, avoid safety hazards, and the mattress can reduce the impact of squeezing and stretching on the mattress when the mattress is bent, so that the mattress has a longer life.
