Description

Technical Field

[0001] This invention relates to the field of electric bed technology, and more particularly to a mattress and an electric bed. Background Technology

[0002] An electric bed typically includes a bed frame, a bed board on the bed frame, and a mattress on the bed board. The bed frame is deformable and includes multiple support frames whose angles can be adjusted. The bed board is connected to the support frames, which can improve the flatness of the bed. The mattress is placed on the bed board, which can improve the comfort of lying down.

[0003] In related technologies, the bed board of an electric bed is typically flat and directly attached to the upper surface of the bed frame. Because the deformable bed frame structure is complex, potentially incorporating mechanical mechanisms such as linkages and gears, it poses a certain degree of danger. Even if the bed frame is subsequently covered with fabric, the fabric's flexibility means it may still extend into the bed frame.

[0004] In addition, the cotton pad is placed on the surface of the bed board. When the bed deforms or is used, the position of the cotton pad is prone to deviating, which affects the comfort of use. Furthermore, if the cotton pad shifts laterally, it may be clamped by the mechanical structure, affecting the normal operation of the electric bed.

[0005] Therefore, it is necessary to improve the relevant technology to overcome the aforementioned defects in the prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a mattress and an electric bed that offer improved safety.

[0007] To achieve the above-mentioned objectives, the present invention provides a mattress comprising:

[0008] Bed frame; and,

[0009] The bed board includes a base plate connected to the bed frame and two side plates respectively connected to both ends of the base plate, the side plates extending toward the side of the bed frame to the outside of the bed frame.

[0010] Furthermore, at least a portion of the side panels are fitted against the sides of the bed frame; or,

[0011] The side panel includes a suspended first end, and the bed board also includes an abutment member connected to the first end and abutting against the side of the bed frame.

[0012] Furthermore, both the substrate and the side plate are made of polyester fiberboard.

[0013] Furthermore, the mattress also includes a flexible pad disposed on the substrate, and the side plate extends toward the side where the flexible pad is located to the outside of the flexible pad.

[0014] Furthermore, the mattress also includes a covering layer that wraps around the bed frame, the bed board, and the flexible pad.

[0015] Furthermore, the bed frame includes a fixed base and a first support frame movably connected to the base. The base plate is connected to the first support frame, and the side plate extends to the outside of the fixed base. During the deformation of the bed frame, the first support frame moves relative to the fixed base along the length direction of the bed frame, and the height of the first support frame changes.

[0016] Furthermore, the side plate includes a first plate portion connected to the base plate, a second plate portion located on the side where the bed frame is located, and a connecting portion that is spaced apart from the first plate portion and the second plate portion, with a through hole formed between the first plate portion, the second plate portion, and two adjacent connecting portions.

[0017] Furthermore, the connecting part is rod-shaped, and when the bed frame is in a horizontal state, the connecting part is vertical or inclined.

[0018] Furthermore, the width of the connecting portion along the length of the bed frame is less than its thickness along the width of the bed frame.

[0019] Furthermore, the bed board also includes a plurality of spaced-apart support rods, one end of which is connected to the second plate portion and the other end of which is connected to the base plate;

[0020] The support rod is perpendicular to the length direction of the bed frame, or the support rod is inclined along the length direction of the bed frame and the inclination direction is consistent.

[0021] Furthermore, the bed board also includes a reinforcing rod connected to a first side and / or a second side of the connecting portion, the first side facing the bed frame and the second side facing away from the bed frame.

[0022] Furthermore, the Young's modulus of the material of the reinforcing rod is greater than that of the Young's modulus of the material of the connecting part.

[0023] On the other hand, the present invention proposes an electric bed, including a mattress as described in any of the preceding claims.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In this invention, side plates extending to the outside of the bed frame are provided on both sides of the base plate. By shielding the outside of the bed frame with the side plates, it can effectively prevent people or objects from accidentally touching the mechanical structure inside the bed frame, thus improving safety.

[0026] 2. As an improvement, the side plates extend to both sides of the flexible pad, which can effectively limit the flexible pad and prevent it from shifting, thus improving reliability.

[0027] 3. As an improvement, the flexible mattress, bed frame, and bed board are all covered with a covering layer, which further enhances the overall safety and makes them more aesthetically pleasing.

[0028] 4. As an improvement, the side panel is provided with multiple spaced connecting parts, forming through holes between adjacent connecting parts. On the one hand, this can reduce the overall weight, and on the other hand, it can facilitate the deformation of the side panel in the height and length directions, thus making it suitable for use in structures where the height and length of the bed frame may change.

It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0050] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] like Figures 1 to 19 As shown, the present invention proposes a mattress, which includes a bed frame 1 and a bed board 2 mounted on the bed frame 1.

[0052] The bed frame 1 includes a fixed base 10 and multiple adjustable support frames 11. The support frames 11 support different parts of the human body, allowing the bed frame 1 to change the person's posture when deformed. (Refer to Figures 1 to 10) Figure 3 , Figure 1 The diagram shows the structure of the bed frame 1 in a horizontal state (initial state). Figure 2 The front view of bed frame 1 when it is in a zero-gravity state is shown. Figure 3 The front view of bed frame 1 in a relaxed state is shown. Figures 1 to 3 In the illustrated embodiment of the bed frame 1, the bed frame 1 includes four support frames 11, namely a first support frame 110, a second support frame 111, a third support frame 112, and a fourth support frame 113. The first support frame 110 supports the buttocks, the second support frame 111 supports the back, the third support frame 112 supports the thighs, and the fourth support frame 113 supports the lower legs. When one of the support frames 11 is driven by a drive device, all support frames 11 move synchronously under the action of a linkage mechanism 15, such as an electric push rod 12. A fixed base 10 is located below the first support frame 110 and is connected to it.

[0053] like Figure 4 As shown, the bed board 2 includes a base plate 20 connected to the bed frame 1 and two side plates 21 respectively connected to both ends of the base plate 20. The side plates 21 extend towards the side of the bed frame 1 to the outside of the bed frame 1. Specifically, each support frame 11 includes two crossbars 114 spaced apart along the transverse direction of the bed frame 1 (i.e., the direction indicated by arrow Y in the figure). The base plate 20 is connected to the upper surface of the crossbars 114, and the base plate 20 can be connected to the crossbars 114, for example, by bolts. The side plates 21 extend downward and cover the outside of the bed frame 1 (for example, they can block the linkage mechanism 15), which can effectively prevent external objects from accidentally entering the bed frame 1 from the side, thus improving safety.

[0054] To improve the stability of the side panel 21, in a first preferred embodiment, at least a portion of the side panel 21 is configured to fit against the side surface 1a of the bed frame 1. In this case, the side panel 21 is less prone to bending or deformation due to lateral forces because it is supported laterally by the bed frame 1. The side panel 21 has a suspended first end 210, which is the end of the side panel 21 located below the base plate 20. Preferably, the first end 210 of the side panel 21 is configured to fit against the side surface 1a of the bed frame 1, in which case the lateral support effect of the bed frame 1 on the side panel 21 is better. Referring to Figure 5, Figure 5 A side view showing the bed board 2, the fixing seat 10, and the first support frame 110 connected together is shown. In the figure, the outer surfaces of the first support frame 110 and the fixing seat 10 are flush, together forming the side surface 1a of the bed frame 1. The side plate 21 is fitted to both the first support frame 110 and the fixing seat 10. In the second preferred embodiment, refer to... Figure 6 The first end 210 of the side plate 21 is suspended and there is a certain gap between it and the side 1a of the bed frame 1. The bed plate 2 also includes an abutment 3 connected to the first end 210. The abutment 3 abuts against the side 1a of the bed frame 1 (the abutment 3 abuts against the fixed seat 10 in the figure), which can improve the strength of the side plate 21. Even if the first end 210 of the side plate 21 is subjected to a lateral force, it will not deform.

[0055] It is understandable that the two implementation methods described above can limit the lateral position of the bed board 2, preventing the bed board 2 from shifting laterally relative to the bed frame 1 during use. At the same time, it can reduce the deformation of the side panel 21 under lateral force, preventing cracking at the connection between the side panel 21 and the base plate 20, and also preventing the side panel 21 from deforming under force after the mattress is covered with fabric, resulting in a flatter mattress side and a more aesthetically pleasing overall appearance.

[0056] In a preferred embodiment, both the substrate 20 and the side plate 21 are made of polyester fiberboard. Polyester fiberboard is produced by thermally processing and pressing polyester fibers, for example, by a series of processes including opening and carding, web laying, needle punching, pressing, and heat setting of the raw material (PET fiber). This purely physical production process ensures that it is non-toxic and harmless. Polyester fiberboard has a porous structure and possesses many advantages such as good toughness, lightweight, minimal susceptibility to temperature and humidity changes, and low noise.

[0057] To improve mattress comfort, refer to Figure 7 The mattress also includes a flexible pad 4 disposed on the upper surface of the base plate 20. The flexible pad 4 can be, for example, a sponge pad or a latex pad. The upper end of the side plate 21 also extends out of the base plate 20. Specifically, the side plate 21 extends toward the side where the flexible pad 4 is located and covers the outside of the flexible pad 4. In this way, the lateral position of the flexible pad 4 can be limited by the side plate 21, preventing the flexible pad 4 from detaching from the base plate 1 during the deformation of the bed frame 1, making its use more reliable.

[0058] Further reference Figure 7 The mattress also includes a covering layer 5 that wraps around the bed frame 1, bed board 2, and flexible mattress 4. The covering layer 5 is made of fabric, such as cotton, linen, nylon, or polyester. Of course, besides fabric, the covering layer 5 can also be made of other materials suitable for covering and contact with the human body. The covering layer 5 covers the bed frame 1, bed board 2, and flexible mattress 4 to form the mattress. Because the bed frame 1 has side panels 21 on its outer side, the sides of the mattress are flatter. In a horizontal position, the entire mattress is roughly rectangular, consistent with the appearance of a traditional mattress, and more aesthetically pleasing.

[0059] During the deformation of the bed frame 1, the fixed seat 10 remains stationary. The first support frame 110, used to support the buttocks, is movably connected to the fixed seat 10 and can change position relative to the fixed seat 10. In some embodiments, the first support frame 110 can move relative to the fixed seat 10 along the length direction of the bed frame 1 (i.e., the direction indicated by arrow X in the figure) during the deformation of the bed frame 1, and its position in the height direction (i.e., the direction indicated by arrow Z in the figure) changes, preferably by decreasing in height. In this way, the height of the first support frame 110 decreases during the deformation of the bed frame 1, which can reduce the magnitude of the change in the center of gravity of the human body, making it more energy-efficient and comfortable.

[0060] For example, refer to Figure 8 Two connecting rods 150 connect the two ends of the first support frame 110 to the fixed base 10, forming a parallelogram mechanism. As the first support frame 110 moves to the left or right, the distance between it and the fixed base 10 gradually decreases. For example, see reference... Figure 9 , Figure 9 It shows Figures 1 to 3 The structure of the connection between the fixed seat 10 and the first support frame 110 of the middle bed frame 1: the left side of the first support frame 110 is connected to the fixed seat 10 via a connecting rod 150, and the right side is fitted into the arc-shaped hole 100 of the fixed seat 10 via a rotating shaft 151. The arc-shaped hole 100 is higher at both ends and lower in the middle. During the process of switching the bed frame 1 from a horizontal state to a leisure state, the first support frame 110 moves towards the side where the second support frame 111 is located. During the movement, the left end of the first support frame 110 always moves closer to the fixed seat 10, while the right end first moves closer to the fixed seat 10 and then moves away from the fixed seat 10. Thus, in the leisure state (refer to...), the first support frame 110... Figure 3 Its right end is higher than its left end, so it is not easy for a person to slide down when resting against the second support frame 111, and in zero-gravity sleeping mode (see reference). Figure 2 The left end of the first support frame 110 is higher than the right end, making it more relaxed.

[0061] Understandably, the side plate 21 of the bed board 2 located on the first support frame 110 preferably extends to the outside of the fixed seat 10 so that it can more comprehensively cover the gap between the first support frame 110 and the fixed seat 10. However, since there will be relative displacement between the first support frame 110 and the fixed seat 10, the side plate 21 extending to the outside of the fixed seat 10 will affect the displacement of the first support frame 110. For example, after the covering layer 5 is wrapped, the lower end of the side plate 21 is close to the fixed seat 10, and it is easy to bulge outward or inward due to compression during the movement of the first support frame 110, which may even cause it to break in severe cases; or the lower end of the side plate 21 may come into contact with the bed frame or other fixed objects and cannot move downward, thus bulging outward or inward.

[0062] To solve this problem, refer to Figure 10 and Figure 11 The side plate 21 includes a first plate portion 211 connected to the base plate 20, a second plate portion 212 located on the side where the bed frame 1 is located, and a plurality of connecting portions 213 spaced apart between the first plate portion 211 and the second plate portion 212. A through hole 214 is formed between the first plate portion 211, the second plate portion 212, and two adjacent connecting portions 213. Because the width of the connecting portion 213 is relatively small, it is more prone to deformation. When the first plate portion 211 and the second plate portion 212 undergo relative displacement, the connecting portion 213 can tilt. Figure 12 (As shown in the tilted case) or bent and deformed towards the through hole 214, the distance between the first plate portion 211 and the second plate portion 212 is reduced. Since the side plate 21 is made of a flexible material such as polyester fiber, it will not be damaged even if the connecting portion 213 undergoes significant deformation. Thus, the side plate 21 improves safety while not affecting the deformation of the first support frame 110. Furthermore, the second plate portion 212 of the side plate 21 can be fixed relative to the fixing base 10, preventing friction noise and making it quieter.

[0063] The shape of the through hole 214 is not limited, and can be, for example, rectangular, rhomboid, parallelogram, elliptical, etc. In a preferred embodiment, the connecting part 213 is rod-shaped. When the first support frame 110 moves horizontally relative to the fixed base 10, the rod-shaped connecting part 213 can deform more easily, reducing obstruction to the movement of the first support frame 110. In this case, the shape of the through hole 214 can be rectangular, rhomboid, or parallelogram, etc., to form the rod-shaped connecting part 213.

[0064] Furthermore, in the first embodiment, reference is made to... Figure 10 and Figure 13The connecting portion 213 is configured such that its width B along the length direction of the bed frame 1 is smaller than its thickness D along the width direction of the bed frame 1 (i.e., the transverse direction mentioned above). This results in the rod-shaped connecting portion 213 having less stiffness along its length than in its transverse direction, making it easier to tilt and bend along its length but less likely to tilt and bend along its transverse direction, thus reducing obstruction to the movement of the first support frame 110. In the second embodiment, as... Figure 14 and Figure 15 As shown, the bed board 2 also includes a plurality of parallel support rods 6. One end of the support rod 6 is connected to the second plate part 212, and the other end is connected to the base plate 20. The support rods 6 strengthen the lateral strength of the side plate 21, so that the connecting part 213 is more likely to undergo tilting or bending deformation in the length direction during deformation, and is less likely to undergo lateral deformation.

[0065] In some embodiments (e.g.) Figures 1 to 3 As shown in the bed frame diagram, during the transition of the bed frame 1 from a horizontal state to other states, the first support frame 110 moves only relative to the fixed base 10 towards the direction of the second support frame 111. In a preferred embodiment, the through hole 214 is parallelogram-shaped, such as... Figure 16 As shown, the connecting part 213 is in the shape of a rod inclined to the same side, with its upper end closer to the second support frame 111. This makes it easier for the connecting part 213 to tilt and deform when moving in the direction of the second support frame 111 (arrow A direction). In other embodiments, such as... Figure 17 As shown, the bed board 2 includes the support rod 6 mentioned above. The support rod 6 is inclined along the length of the bed frame 1, and its lower end is closer to the second support frame 111 than its upper end. In this way, in the initial state, the first support frame 110 is more likely to move toward the side where the second support frame 111 is located, and is less likely to move in the opposite direction.

[0066] Understandably, when the first support frame 110 needs to move bidirectionally relative to its initial position, the rod-shaped connecting portion 213 is preferably vertical in the initial state, and the first support rod 110 is preferably perpendicular to its length direction in the initial state, so that the movement of the first support frame 110 towards the bed frame 1 in both the front and rear directions is smoother. Furthermore, when the first support frame 110 needs to be raised when moving from its initial position, the through hole 214 can be set as a parallelogram, for example... Figure 16 In the middle, when the first plate part 211 moves in the opposite direction of arrow A, it has a tendency to rise.

[0067] like Figure 18 and Figure 19As shown, the mattress may further include a reinforcing rod 7 connected to a first side 2130 and / or a second side 2131 of the connecting portion 213, wherein the first side 2130 is the surface of the connecting portion 213 facing the bed frame 1, and the second side 2131 is the surface of the connecting portion 213 facing away from the bed frame 1. Because of the reinforcing rod 7, the support performance of the connecting portion 213 is enhanced without affecting the tilting deformation of the connecting portion 213. Preferably, the Young's modulus of the reinforcing rod 7 is greater than that of the connecting portion 213, and it is made of materials such as iron, aluminum, or plastic, which are less prone to bending and deformation, thus improving the support performance of the connecting portion 213. The reinforcing rod 7 is preferably disposed on the first side 2130, with its upper end extending to the first plate portion 211.

[0068] This invention also proposes an electric bed, which includes the mattress described above. The electric bed also includes a bed frame placed on a fixed surface such as the ground, with the mattress placed on the bed frame. The fixing seats 10 of the bed frame 1 can be fixed to the bed frame, or they can be placed on the bed frame without being connected to each other. When the fixing seats 10 are not connected to the bed frame, the mattress has higher safety, as no shearing structure is formed between the mattress's support frames 11 and the bed frame, making it less likely to pinch or injure a person or object located between the mattress and the bed frame.

[0069] The above are merely specific embodiments of the present invention, and any improvements made based on the concept of the present invention shall be considered within the scope of protection of the present invention.
