Description

Technical Field

[0001] This utility model relates to the field of electric bed technology, and in particular to a mattress limiting device and an electric bed. Background Technology

[0002] Electric beds are bed frames with adjustable headboard or footboard height and freely adjustable bed board curvature. They are divided into two main categories: slatted bed frames and flat bed frames, and are commonly used in homes or medical settings. For all electric beds currently available, the problem of the mattress slipping off when the bed is raised needs to be addressed.

[0003] When an electric bed is folded up, its surface area decreases, causing the mattress placed on it to fold, especially if the mattress is thick or has internal edge protection. The mattress cannot fit snugly when the bed is raised and is difficult to return to its original position automatically when lowered, severely impacting the user experience. Existing solutions mostly limit mattress movement by adding fixed barriers at the head or foot of the bed, but this often causes excessive pressure on the mattress, resulting in deformation or damage.

[0004] Therefore, there is an urgent need for mattress limiting devices and electric beds to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mattress limiting device to ensure that the mattress always maintains a good fit with the bed frame during the lifting and lowering process, and to prevent the mattress from being deformed or damaged due to excessive compression.

[0006] To address the aforementioned problems in the existing technology, this utility model adopts the following technical solution:

[0007] A mattress limiting device, installed on a bed frame, the bed frame having connecting holes, the mattress limiting device comprising:

[0008] A stop bar, which passes through the connecting hole and is used to block the mattress on the bed frame, and the stop bar can slide relative to the bed frame along the length of the bed frame;

[0009] An elastic element is disposed between the stop bar and the bed frame, and the elastic element is configured to provide a spring force that causes the stop bar to slide in a direction closer to the bed frame when the stop bar slides in a direction away from the bed frame.

[0010] Preferably, the mattress limiting device further includes an adjusting member, which is rotatably mounted on the stop bar. One end of the elastic member is connected to the bed frame, and the other end of the elastic member is connected to the adjusting member. When the adjusting member rotates, it slides along the stop bar.

[0011] Preferably, the adjusting member is provided with a screw hole, and the stop rod is provided with an external thread that mates with the screw hole; or,

[0012] The stop bar is provided with a screw hole, and the adjusting component is rotatably connected to the screw hole.

[0013] Preferably, the stop bar includes a blocking part and a connecting part, the connecting part is connected to the blocking part and the connecting part is slidably inserted through the connecting hole, the connecting part is fitted with the elastic member, the height of the blocking part is higher than the mattress surface of the bed frame along the height direction of the bed frame, and the adjusting member is rotatably disposed at the end of the connecting part away from the blocking part.

[0014] Preferably, the blocking part is configured as an inverted U-shaped, rectangular, triangular, or circular structure.

[0015] Preferably, there are two adjusting members and two connecting parts, with the two connecting parts respectively connected to both ends of the blocking part, and the two adjusting members respectively disposed on the corresponding connecting parts.

[0016] Preferably, the axial direction of the connecting part and the movement direction of the adjusting member are both perpendicular to the length direction of the blocking part.

[0017] Preferably, the mattress limiting device further includes a limiting member, which is sleeved on the connecting portion, and the length of the limiting member is less than the length of the connecting portion.

[0018] Preferably, the elastic element is a return spring.

[0019] To achieve the above objectives, this utility model also provides an electric bed, including a bed frame and the aforementioned mattress limiting device, wherein the mattress limiting device is disposed on the bed frame.

[0020] The beneficial effects of this utility model are as follows:

[0021] The mattress limiting device provided by this utility model has a stop bar inserted through a connecting hole, which can slide relative to the bed frame along its length. An elastic element is disposed between the stop bar and the bed frame, and is configured to provide elastic force to make the stop bar slide closer to the bed frame when it slides away from the bed frame. When the bed frame is in a flat position, the stop bar blocks the mattress on the bed frame. During the lifting process, the mattress compresses the stop bar, causing it to move away from the bed frame. Under the elastic action of the elastic element, the stop bar clamps the mattress. Because the stop bar can extend and adjust along the length of the bed frame, it provides a certain cushioning effect, effectively protecting the internal materials and structure of the mattress and ensuring that the mattress always maintains a good fit with the bed frame, preventing the mattress from deforming or being damaged due to excessive compression. When the bed frame returns to a flat position, under the elastic action of the elastic element, the stop bar retracts along the length of the bed frame. At the same time, the stop bar pushes the mattress, ensuring that the edges of the mattress can smoothly return to their original position, achieving a perfect fit between the mattress and the bed frame.

[0022] The electric bed provided by this utility model includes a bed frame and a mattress limiting device, with the mattress limiting device mounted on the bed frame. During the lifting process, the mattress presses against the retaining bar, and under the elastic action of the elastic element, the retaining bar extends along the length of the bed frame, providing a certain cushioning effect and effectively protecting the internal materials and structure of the mattress. This ensures that the mattress always maintains a good fit with the bed frame, preventing deformation or damage due to compression. When the bed frame returns to the flat position, under the elastic action of the elastic element, the retaining bar retracts along the length of the bed frame. Simultaneously, the retaining bar pushes the mattress, ensuring that the edges of the mattress can smoothly return to their original position, achieving a perfect fit between the mattress and the bed frame.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] like Figures 1-3 As shown, in this embodiment, a mattress limiting device is installed on the bed frame 100, which has a connecting hole. The limiting device includes a stop bar 1 and an elastic member 2. The stop bar 1 passes through the connecting hole and is used to block the mattress on the bed frame 100. Along the length of the bed frame 100, the stop bar 1 can slide relative to the bed frame 100. The elastic member 2 is disposed between the stop bar 1 and the bed frame 100. The elastic member 2 is configured to provide a spring force that causes the stop bar 1 to slide in a direction closer to the bed frame 100 when the stop bar 1 slides in a direction away from the bed frame 100.

[0036] Specifically, the mattress limiting device is installed at the head or tail of the bed frame 100. The edge of the bed frame 100 has connecting holes, and the stop bar 1 is installed on the edge of the bed frame 100 through the connecting holes. The stop bar 1 slides through the connecting holes so that it can slide relative to the bed frame 100 along its length. The elastic element 2 can be located on the inner side of the bed frame (e.g., Figure 1 and Figure 2 As shown in the figure, the elastic element 2 can also be located on the outside of the bed frame (not shown in the figure). When the elastic element 2 is located on the inside of the bed frame, the elastic element 2 is in a compressed state when the stop bar 1 slides outward along the length of the bed frame 100. The elastic element 2 provides a spring force that causes the stop bar 1 to slide in a direction close to the bed frame 100 (i.e., drives the stop bar 1 to slide inward toward the bed frame 100). When the elastic element 2 is located on the outside of the bed frame, the elastic element 2 is in a stretched state when the stop bar 1 slides inward along the length of the bed frame 100. The elastic element 2 provides a spring force that causes the stop bar 1 to slide in a direction close to the bed frame 100 (i.e., drives the stop bar 1 to slide inward toward the bed frame 100). For ease of explanation, the following example uses the elastic element 2 located on the inside of the bed frame.

[0037] When the bed frame 100 is in a flat position, the stop bar 1 blocks the mattress on the bed frame 100 (not shown). During the lifting process, the mattress presses against the stop bar 1, causing the stop bar to move away from the bed frame. Under the elastic action of the elastic element 2, the stop bar 1 clamps the mattress. Because the stop bar 1 extends and adjusts along the length of the bed frame 100, it provides a certain cushioning effect, effectively protecting the internal materials and structure of the mattress and ensuring that the mattress always maintains a good fit with the bed frame 100, preventing the mattress from being deformed or damaged by compression. When the bed frame 100 returns to a flat position, under the elastic action of the elastic element 2, the stop bar 1 retracts along the length of the bed frame 100. At the same time, the stop bar 1 pushes the mattress, ensuring that the edges of the mattress can smoothly return to their original position, achieving a perfect fit between the mattress and the bed frame 100.

[0038] Furthermore, continue to refer to Figures 1-3 The mattress limiting device also includes an adjusting member 3, which is rotatably mounted on the stop bar 1. One end of the elastic member 2 is connected to the bed frame 100, and the other end is connected to the adjusting member 3. When the adjusting member 3 rotates, it slides along the stop bar 1. Specifically, the elastic member 2 is sleeved on the stop bar 1, and the adjusting member 3 can rotate relative to the stop bar 1 to adjust the degree of compression of the elastic member 2, thereby adjusting the maximum outward extension of the stop bar 1 relative to the bed frame 100 to accommodate different mattress sizes and mattress stretchability, while meeting the needs of different users. It can be understood that the higher the degree of compression of the elastic member 2, the shorter the outward extension length of the stop bar 1; conversely, the lower the degree of compression of the elastic member 2, the longer the outward extension length of the stop bar 1.

[0039] Furthermore, continue to refer to Figures 1-3 The adjusting element 3 has a screw hole, and the stop rod 1 has an external thread that mates with the screw hole; or, the stop rod 1 has a screw hole, and the adjusting element 3 is rotatably connected to the screw hole. Specifically, the adjusting element 3 can be configured as an adjustable screw, that is, the outer circumference of the adjusting element 3 has an external thread, and the adjusting element 3 is connected to the stop rod 1 through the screw hole; or, the stop rod 1 can be configured as an adjustable screw, that is, the outer circumference of the stop rod 1 has an external thread, and the stop rod 1 is connected to the adjusting element 3 through the screw hole. The adjusting element 3 can rotate relative to the stop rod 1, and the adjusting element 3 can gradually move away from or gradually move closer to the edge of the bed frame 100 to adjust the degree of compression of the elastic element 2 to accommodate different mattress sizes and mattress stretchability.

[0040] Furthermore, continue to refer to Figures 1-3 The stop bar 1 includes a blocking part 11 and a connecting part 12. The connecting part 12 is connected to the blocking part 11 and slides through the connecting hole. An elastic member 2 is sleeved on the connecting part 12. Along the height direction of the bed frame 100, the height of the blocking part 11 is higher than the mattress surface of the bed frame 100. An adjusting member 3 is rotatably disposed at the end of the connecting part 12 away from the blocking part 11. Specifically, the blocking part 11 is configured as an inverted U-shaped, rectangular, triangular, or circular structure. In this embodiment, the blocking part 11 is an inverted U-shaped structure, and the blocking part 11 is a U-shaped crossbar. The connecting part 12 is a connecting rod. There are two adjusting members 3 and two connecting parts 12. The two connecting parts 12 are respectively connected to the two ends of the blocking part 11, and the two adjusting members 3 are respectively disposed on the corresponding connecting parts 12. The axial direction of the connecting part 12 and the movement direction of the adjusting member 3 are both perpendicular to the length direction of the blocking part 11. During the lifting process of the bed frame 100, the mattress pushes the blocking part 11, the two elastic elements 2 are compressed, and the two connecting parts 12 slide and extend relative to the bed frame 100 to provide sufficient compression space for the mattress and avoid excessive pressure on the mattress. When the bed frame 100 returns to the flat position, under the action of the two elastic elements 2, the two connecting parts 12 retract, and the blocking part 11 pushes the mattress, allowing the edge of the mattress to return to its original position, achieving a perfect fit between the mattress and the bed frame 100.

[0041] Furthermore, continue to refer to Figures 1-3 The mattress limiting device also includes a limiting member (not shown in the figure), which is sleeved on the connecting part 12, and the length of the limiting member is less than the length of the connecting part 12. Specifically, the limiting member is a sleeve, which is sandwiched between the connecting part 12 and the elastic member 2 along the circumferential direction of the connecting part 12. During the lifting of the bed frame 100, the connecting part 12 slides relative to the bed frame 100 and is extended and adjusted until the blocking part 11 extends a certain length relative to the bed frame 100 and then remains stationary. The limiting member plays a limiting role, preventing the blocking rod 1 from moving excessively and ensuring the stability and safety of the mattress limiting device.

[0042] This embodiment also provides an electric bed, including a bed frame 100 and a mattress limiting device, which is mounted on the bed frame 100. Specifically, during the lifting process of the bed frame 100, the mattress presses against the stop bar 1, compressing the elastic element 2. Furthermore, under the elastic action of the elastic element 2, the stop bar 1 extends along the length of the bed frame 100, providing a certain cushioning effect and effectively protecting the internal materials and structure of the mattress. This ensures that the mattress always maintains a good fit with the bed frame 100, preventing deformation or damage due to compression. When the bed frame 100 returns to a flat position, under the elastic action of the elastic element 2, the stop bar 1 retracts along the length of the bed frame 100. Simultaneously, the stop bar 1 pushes the mattress, ensuring that the edges of the mattress can smoothly return to their original position, achieving a perfect fit between the mattress and the bed frame 100.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
