Description

Technical Field

[0001] This utility model relates to beds, and more particularly to a sleeping bed with alternating sinking of the bed board. Background Technology

[0002] As we all know, prolonged bed rest can cause soreness, swelling, and pain in areas of the body that are in contact with the bed, especially the neck, shoulders, back, waist, buttocks, and thighs. Before falling asleep, people may try to relieve these symptoms by turning over or adjusting their posture. After falling asleep, these discomforts can disrupt deep sleep and lead to light sleep, causing people to unconsciously turn over or adjust their posture to alleviate the discomfort, thus affecting sleep quality. Patients, disabled individuals, and overweight people often experience bedsores and organ failure due to difficulty turning over in such beds. This demonstrates the significant harm that prolonged pressure on the same body position can cause. To address this issue, many nursing beds or massage beds on the market offer position-changing features, allowing for different areas of contact between the body and the bed to avoid prolonged pressure on specific parts of the body that can cause soreness, swelling, and pain. However, these are primarily nursing or massage beds designed for patients and do not consider the sleep needs of healthy individuals. They also suffer from complex structures and high manufacturing and operating costs. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a sleeping bed with alternating sinking of the bed board to solve the technical problems mentioned in the background art.

[0004] The objective of this utility model is achieved through the following technical solution: A type of alternating sinking bed includes a bed frame with bed boards mounted on it. Each bed board is composed of a movable bed board mechanism or a combination of a fixed bed board and a movable bed board mechanism. The movable bed board mechanism includes three or more sinking boards and a drive mechanism. The sinking boards are all arranged along the length of the bed. The drive mechanism includes a linear motion mechanism and a slider located below the sinking boards. The linear motion mechanism drives the slider to move along the width of the bed. The contact surface between the slider and the sinking boards is provided with an arc-shaped curved surface. The arc-shaped curved surface must ensure that at least two of the sinking boards in contact with it are not sinking.

[0005] Furthermore, rollers are provided on the sunken plate, and the rollers are in contact with the slider.

[0006] Furthermore, two rollers are installed on the sunken plate, and the two rollers are connected in series by a rotating shaft.

[0007] Furthermore, it also includes crossbeams located at both ends of the sunken plate, with the same number of grooves as the rotating shafts on the crossbeams, and each end of the rotating shaft has a moving block, which is located in the groove.

[0008] Furthermore, it also includes a slide rail, with both ends of the slide rail mounted on the bed frame, and the slider positioned above the slide rail.

[0009] Furthermore, in the configuration where the bed board is composed of a combination of a fixed bed board and a movable bed board mechanism, the sunken plate is located in the cuboid region where the human body contacts the bed board.

[0010] Furthermore, in the configuration where the bed board is composed of a combination of a fixed bed board and a movable bed board mechanism, the length of the sunken board is the length from the neck to the knee of the human body, and the width of three or more sunken boards is not less than the width of the human body.

[0011] The beneficial effects of this utility model are: The alternating sinking type sleeping bed proposed in this utility model includes a movable bed board mechanism. The linear motion mechanism of the movable bed board mechanism drives the slider to move along the width of the bed. Under the guidance of the arc-shaped curved surface of the slider, three or more sinking boards alternately sink, ultimately realizing the change of the contact area between the human body and the bed board, thereby greatly reducing the problems of soreness, swelling and pain caused by prolonged pressure on local parts of the body.

[0012] The drive mechanism of this sleeping bed consists of only a linear motion mechanism and a slider, which is simple to control and has low manufacturing and operating costs.

[0013] The sunken panel of this sleeping bed is set along the length of the bed, conforming to the natural flow of blood in the human body, which can more efficiently help blood circulation and improve sleep comfort.

[0014] The sinking plate contacts the slider through rollers, resulting in low friction and smooth operation. When there are two rollers, the support stability of the sinking plate is good and the structure is simple.

[0015] The groove on the crossbeam limits the rotation shaft, so that the sinking plate can only move up and down.

[0016] The track supports the slider.

[0017] The length of the sunken board is the same as the length from the neck to the knee of a human body, which simplifies the bed board structure to the greatest extent.

[0018] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0028] Example 1 like Figure 1-6 The bed shown is a sleeping bed with alternating sinking bed boards. It includes a bed frame 1, on which a bed board 2 is provided. The bed board 2 is composed of a movable bed board mechanism or a combination of a fixed bed board 3 and a movable bed board mechanism. If the bed surface is narrow, it is recommended that the bed board 2 be directly built by the movable bed board mechanism. If the bed surface is wide, it is recommended that the bed board 2 be a combination of a fixed bed board 3 and a movable bed board mechanism.

[0029] The movable bed board mechanism includes three or more sunken plates 4 and a drive mechanism. Preferably, there are five or more sunken plates 4. All sunken plates 4 are arranged along the length of the bed. The drive mechanism includes a linear motion mechanism 5 and a slider 6 located below the sunken plates 4. The linear motion mechanism 5 drives the slider 6 to run along the width of the bed. An arc-shaped curved surface 7 is provided on the contact surface between the slider 6 and the sunken plates 4. The arc-shaped curved surface 7 must ensure that at least two of the sunken plates 4 in contact with it are not sunken.

[0030] The arc-shaped surface 7 can be as follows: Figure 6 The arc-shaped surface 7 with multiple concave surfaces 20 can also be as follows: Figure 7 The single concave arc-shaped surface 7 is shown.

[0031] The proposed sleep bed with alternating sinking of the bed board includes a movable bed board mechanism. The linear motion mechanism 5 of the movable bed board mechanism drives the slider 6 to move along the width of the bed. Guided by the arc-shaped curved surface 7 of the slider 6, three or more sinking boards 4 alternately or sequentially sink, ultimately changing the contact area between the human body and the bed board 2. This avoids or reduces the occurrence of soreness, swelling, and pain caused by prolonged pressure on certain parts of the body. The drive mechanism of this sleep bed only includes the linear motion mechanism 5 and the slider 6, making it simple to control and inexpensive to manufacture and use. The sinking boards 4 of this sleep bed are set along the length of the bed, conforming to the natural flow trajectory of blood in the human body, which can more efficiently promote blood circulation and improve sleep comfort.

[0032] Example 2 like Figure 1-5The illustrated alternating sunken bed includes a standard bed frame 1, on which bed boards 2 are mounted. Each bed board is composed of a fixed bed board 3 and a movable bed board mechanism. The fixed bed board 3 is a standard bed board, while the movable bed board mechanism includes three or more sunken boards 4 and a drive mechanism. The sunken boards 4 are all positioned along the length of the bed, with a length equal to the distance from the neck to the knee. The width of the three or more sunken boards 4 is not less than the width of the human body. Connecting blocks 8 are attached to both ends of the bottom surface of each sunken board 4, and rotating shafts 9 are connected to the lower ends of two connecting blocks 8. Rollers 10 are fitted onto both ends of the rotating shafts 9. The drive mechanism includes a linear motion mechanism 5 and two sliders 6 located below the sunken plate 4. The two sliders 6 are connected by a connecting plate 11. The linear motion mechanism 5 drives the sliders 6 to move along the width of the bed through the connecting plate 11. The linear motion mechanism 5 can be an electric telescopic rod, a hydraulic cylinder, a pneumatic cylinder, or a conventional mechanical structure. The upper surface of the slider 6 is composed of alternating planes 12 and concave arc-shaped curved surfaces 7. Two sets of rollers 10 on adjacent sunken plates 4 are located, one set on the plane 12 of the slider 6 and the other set within the arc-shaped curved surface 7. The sleeping bed also includes crossbeams 13 located at both ends of the sunken plate 4. The two ends of the crossbeams 13 are connected to the bed frame 1. The crossbeams 13 have the same number of grooves 14 as the number of rotating shafts. Movable blocks 15 are provided at both ends of the rotating shafts 9. The movable blocks 15 at both ends of the rotating shafts 9 slide within the grooves 14. The sleeping bed also includes a slide rail 16, with both ends of the slide rail 16 mounted on the bed frame 1. Two sliders 6 are set on the slide rail 16. The slide rail 16 is a U-shaped plate. The U-shaped plate and two crossbeams 13 form a pod 17 with an opening at the top. The fixed end of the linear motion mechanism 5 is fixed to the inner wall of the pod 17.

[0033] Three or more sunken slabs 4 Figure 2 As shown, the slides are numbered sequentially from left to right. Initially, the odd-numbered slide plate 4 rollers 10 are in contact with the plane 12 of the slider 6, and the even-numbered slide plate 4 rollers 10 are in contact with the curved surface 7 of the slider 6. After the linear motion mechanism 5 drives the slider 6 to the left, the odd-numbered slide plate 4 rollers 10 are in contact with the curved surface 7 of the slider 6, and the even-numbered slide plate 4 rollers are in contact with the plane of the slider 6. Then the linear motion mechanism 5 drives the slider 6 to the right, and so on, so that more than three slide plates 4 alternately sink.

[0034] In this embodiment, the sunken plate 4 contacts the slider 6 via two rollers 10, resulting in low friction, smooth operation, good support stability, and a simple structure. The groove 14 on the crossbeam 13 limits the rotation shaft 9, allowing the sunken plate 4 to move only up and down. The track 16 supports the slider 6. The length of the sunken plate 4 is the same as the length from the human neck to the knee, allowing for changes in the contact area between the human neck, shoulders, back, waist, hips, and thighs and the bed board, while maximizing the simplification of the bed board 2 structure.

[0035] Example 3 The difference from Embodiment 2 is that the sunken plate 4 is located in the cuboid area where the human body contacts the bed board, thereby changing the contact area between the entire human body and the bed board 2.

[0036] Example 4 The difference from Embodiment 2 is that the bed board 2 is composed of a movable bed board mechanism, and the length of the sunken plate 4 is the length of the bed board.

[0037] Example 5 like Figure 6 The bed shown is a type of alternating sinking bed, which includes a regular bed frame 1, and a bed board 2 on the bed frame 2. The bed board 2 is composed of a combination of a fixed bed board 3 and a movable bed board mechanism. The fixed bed board is a regular bed board, and the movable bed board mechanism includes three or more sinking boards 4 and a drive mechanism. All the sunken plates 4 are set along the length of the bed. The length of the sunken plate 4 is the length from the neck to the knee of the human body. The thickness of the sunken plate 4 is greater than its width. The lower two sides of the sunken plate 4 are rounded. Three or more sunken plates 4 are attached to each other. The width of the three or more sunken plates 4 is not less than the width of the human body. Limiting blocks 18 are attached to both sides of the three or more sunken plates 4. The two ends of the limiting blocks 18 are fixed to the bed frame 1. The driving mechanism includes a linear motion mechanism 5 and two sliders 6 located below the sunken plates 4. The two sliders 6 are connected by a connecting plate 11. The linear motion mechanism 5 drives the sliders 6 to run along the width of the bed through the connecting plate 11. The fixed end of the linear motion mechanism 5 is fixed to the bed frame 1. The linear motion mechanism 5 is an electric telescopic rod, hydraulic cylinder, pneumatic cylinder or conventional mechanical structure. The contact surface between the slider 6 and the sunken plate 4 is an arc-shaped curved surface 7. The arc-shaped curved surface 7 is a continuous S-shape in the longitudinal section in the width of the bed. One of the two adjacent sunken plates 4 is located on the convex surface 19 of the slider 6, and the other is located in the concave surface 20 of the slider 6. The sleeping bed also includes a slide rail 16, with both ends of the slide rail 16 mounted on the bed frame 1, and two sliders 6 mounted on the slide rail 19.

[0038] Three or more sunken slabs, such as Figure 6 As shown, the plates are numbered sequentially from left to right. Initially, the odd-numbered sinker plate 4 contacts the concave surface 20 of the slider 6, and the even-numbered sinker plate 4 contacts the convex surface 19 of the slider. After the linear motion mechanism 5 drives the slider 6 to move to the left, the odd-numbered sinker plate 4 contacts the convex surface 19 of the slider 6, and the even-numbered sinker plate 4 contacts the concave surface 20 of the slider 6. Then, the linear motion mechanism 5 drives the slider 6 to move to the right. This process is repeated to achieve the alternating sinking of more than three sinker plates 4.

[0039] In this embodiment, three or more sunken plates 4 are limited by two limiting blocks 18 on each side, and the three or more sunken plates 4 are mutually limited to prevent the sunken plates 4 from moving along the width of the bed. When the linear motion mechanism 5 drives the slider 6 to move along the width of the bed, the three or more sunken plates 4 can only move in the height of the bed. Such a movable bed board mechanism structure for a sleeping bed is simpler.

[0040] Example 6 The difference from Example 5 is that, as Figure 7 As shown, the contact surface between the slider 6 and the sinking plate 4 is composed of a plane and a single concave arc-shaped surface 7. Under the guidance of the arc-shaped surface 7 of the slider 6, three or more sinking plates 4 sink one by one.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
