Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a bed frame. Background Technology

[0002] Existing bed frames include a frame and a support plate assembly mounted on the frame. The top surface of the support plate assembly forms a support surface for supporting the mattress. The support plate assembly includes a fixed part that is fixed to the frame and a movable part that can move relative to the fixed part. The movable part can move relative to the fixed part, making the contour of the support surface variable, thereby changing the shape of the mattress to meet the user's needs in different scenarios. A stop bar is set at the rear edge of the support plate assembly, and a backrest is set at the front edge of the frame. The stop bar and the backrest are used to limit the mattress in the front and back directions, ensuring that the mattress is always above the support surface and deforms synchronously with the support surface. The existing stop bar is formed by bending a rod-like member, including a fixed part formed at the end and assembled with the rear edge of the support plate assembly, and a limiting part set in the middle section. Because the limiting part is rod-shaped, the contact area between the stop bar and the back wall of the mattress is small. This makes the back wall of the bed frame prone to local compression deformation, affecting the service life of the mattress, and also causing wear and tear on the back wall of the mattress, affecting its aesthetics. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a bed frame with a vertical board. A vertical board is provided at the rear edge of the support board assembly to limit the mattress from shifting backward. This effectively increases the contact area between the vertical board and the back wall of the mattress, improving the reliability of the limiting mechanism, protecting the back wall of the mattress, preventing wear, extending the mattress's lifespan, and enhancing its aesthetics.

[0004] This utility model is achieved through the following method: a bed frame with vertical plates, including a frame body and a support plate assembly disposed on the frame body. The support plate assembly includes a fixed part fixedly connected to the frame body and a movable part movable relative to the fixed part. A vertical plate is provided at the rear edge of the support plate assembly, arranged along its width direction. The front wall of the vertical plate forms a limiting surface that allows the back wall of the mattress to abut against it, thereby preventing wear on the back wall of the mattress. Providing a vertical plate at the rear edge of the support plate assembly effectively increases the contact area between the vertical plate and the back wall of the mattress. By using the vertical plate to abut against the back wall of the mattress and restrict the mattress from shifting backward, it improves the reliability of the limiting mechanism, protects the back wall of the mattress, prevents wear, extends the service life of the mattress, and enhances its aesthetics.

[0005] Preferably, the vertical plate is detachably mounted on the rear edge of the support plate assembly via a connector, allowing the vertical plate to move synchronously with the support plate assembly and limit the mattress position. The connector connects the vertical plate and the support plate assembly, facilitating the disassembly and maintenance of the vertical plate and improving assembly efficiency. It also secures the vertical plate, ensuring it effectively prevents the mattress from shifting backward and effectively limits its position, allowing it to deform synchronously with the support surface.

[0006] Preferably, the rear edge of the support plate assembly has a vertically opened mounting hole. The bottom of the connector is inserted into the mounting hole, and the top is fixed to the vertical plate, so that the vertical plate is linked with the rear edge of the support plate assembly. The vertically opened axis of the mounting hole not only facilitates the vertical insertion of the bottom of the connector for easy assembly and disassembly, but also uses the weight of the connector and the vertical plate to limit the connector from disengaging upward from the mounting hole, ensuring connection reliability. It can also effectively resist the horizontal force generated by the mattress shifting backward, effectively improving the limiting reliability.

[0007] Preferably, a sleeve is inserted into the mounting hole. The upper end of the sleeve is folded outward to form a limiting ring. The sleeve is inserted into the mounting hole and overlaps the periphery of the mounting hole through the limiting ring. The bottom of the connector is detachably inserted into the sleeve. With the sleeve and the bottom of the connector inserted into the sleeve, the force on the connector can be distributed to various areas of the inner wall of the mounting hole through the sleeve, preventing deformation due to concentrated force at the periphery of the mounting hole. This ensures that the bottom of the connector always remains vertical, thereby ensuring that the vertical plate can be reliably positioned at the preset work position and limiting the mattress from shifting backward. The limiting ring can overlap the periphery of the upper end of the mounting hole, providing vertical restraint for the sleeve and preventing it from detaching downward from the mounting hole. The support plate assembly is usually made of wood, which has low hardness and is prone to deformation due to localized force. The sleeve is used to distribute the force and ensure that the mounting hole does not deform.

[0008] Preferably, the length of the sleeve is greater than the depth of the mounting hole to increase the contact area between the sleeve and the bottom of the connector. The outer wall of the sleeve can completely cover the inner wall of the mounting hole. By increasing the contact area between the two, the force is dispersed, thereby maintaining the outline of the mounting hole and preventing local deformation of the mounting hole.

[0009] Preferably, the outer wall diameter of the sleeve matches the diameter of the mounting hole. By reducing the gap between the two, the fit and matching are improved, thereby enhancing the force diffusion effect.

[0010] Preferably, the bottom of the connector is tightly inserted into the sleeve to reduce connector wobbling and prevent the vertical board from shifting, which not only provides precise positioning for the mattress but also effectively reduces noise.

[0011] Preferably, the connector is a Z-shaped tube, comprising an integrally bent upper vertical section, a middle horizontal section, and a lower vertical section. The upper vertical section is fixed to the vertical plate by fasteners, and the lower vertical section is detachably inserted into the mounting hole. The connector uses the middle horizontal section to connect the upper and lower vertical sections, ensuring good structural strength and effectively reducing the likelihood of backward deflection due to top force, thus improving positioning reliability. The middle horizontal section is pressed under the mattress, using the mattress's weight to vertically position the connector and ensure that the lower vertical section remains inserted within the sleeve.

[0012] Preferably, the top of the upper vertical part is provided with an L-shaped connecting piece. The connecting piece is attached to the front edge of the bottom of the vertical plate and fixed by fasteners. The connecting piece is tightly attached to the side wall and bottom wall of the bottom of the vertical plate, which not only provides vertical support for the vertical plate, but also provides front and rear limiting function for the vertical plate, ensuring that the force on the vertical plate can be transmitted to the connector through the connecting piece and then borne by the support plate assembly.

[0013] Preferably, the front-to-back distance between the vertical plate and the mounting hole is the same as the length of the middle horizontal section, so that the vertical plate is positioned at the rear edge of the support plate assembly. The middle horizontal section moves the mounting hole forward, ensuring that the periphery of the mounting hole has sufficient thickness to meet usage requirements, thereby improving the structural strength of the periphery of the mounting hole and ensuring that the lower vertical part of the connector can be effectively positioned and maintained in an upright position.

[0014] Preferably, the vertical plate is elongated, and there are three connectors, which are evenly spaced along the bottom edge of the vertical plate. This not only disperses the force from the vertical plate by increasing the number of connectors, but also effectively simplifies the structure and facilitates assembly.

[0015] Preferably, the height of the vertical board is matched with the thickness of the mattress, which increases the contact area between the limiting surface and the back wall of the mattress, effectively disperses the force, prevents the back wall of the mattress from being worn due to localized concentrated force, and also ensures that the top edge of the vertical board is not exposed on the top surface of the mattress, so that the mattress can be used to hide the vertical board.

[0016] Preferably, the fixed part includes a lumbar support plate and a hip support plate fixedly connected front to back, and the movable part includes a back support plate, a thigh plate, and a calf plate, with the vertical plate installed on the rear edge of the calf plate. The back support plate, lumbar support plate, hip support plate, thigh plate, and calf plate are arranged sequentially from front to back to form a support surface for supporting the mattress. The vertical plate is installed on the rear edge of the calf plate, which not only reserves space for the mattress but also restricts the mattress from shifting backward.

[0017] Preferably, the back support plate is pivotally connected to the front edge of the lumbar support plate, the thigh plate is pivotally connected to the rear edge of the hip support plate, and the calf plate is pivotally mounted on the rear edge of the thigh plate. The vertical plate and the calf plate are perpendicularly connected and remain linked. The linkage between the vertical plate and the calf plate, and their constant perpendicularity, ensures that the calf plate and the vertical plate can respectively abut against the rear of the bottom wall and the rear wall of the mattress, effectively improving the positioning effect on the mattress.

[0018] The beneficial effects of this utility model are as follows: A vertical plate is set at the rear edge of the support plate assembly, which effectively increases the contact area between the vertical plate and the back wall of the mattress. The vertical plate abuts against the back wall of the mattress and restricts the mattress from shifting backward, which not only improves the reliability of the limiting position, but also protects the back wall of the mattress, prevents wear and tear, extends the service life of the mattress, and improves its aesthetics.

[0025] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 and 2The illustrated bed frame with vertical panels includes a frame body 1 and a support plate assembly mounted on the frame body 1. The support plate assembly includes a fixed part fixed to the frame body 1 and a movable part movable relative to the fixed part. A vertical plate 2 is provided at the rear edge of the support plate assembly, extending along its width. The front wall of the vertical plate 2 forms a limiting surface that allows the rear wall of the mattress 16 to abut against it, preventing wear on the rear wall of the mattress 16. The vertical plate 2 at the rear edge of the support plate assembly effectively increases the contact area between the vertical plate 2 and the rear wall of the mattress 16. By using the vertical plate 2 to abut against the rear wall of the mattress 16 and restrict the mattress 16 from shifting backward, the reliability of the limiting mechanism is improved, the rear wall of the mattress 16 is protected from wear, the lifespan of the mattress 16 is extended, and the aesthetics are enhanced.

[0027] In actual operation, the fixed part includes a lumbar support plate 11 and a hip support plate 12 fixedly connected front to back, and the movable part includes a back support plate 13, a thigh plate 14, and a calf plate 15. The vertical plate 2 is installed on the rear edge of the calf plate 15. The back support plate 13 is swayably connected to the front edge of the lumbar support plate 11, and the thigh plate 14 is swayably connected to the rear edge of the hip support plate 12. The back support plate 13, lumbar support plate 11, hip support plate 12, thigh plate 14, and calf plate 15 are arranged sequentially from front to back to form a support surface for supporting the mattress 16 (e.g., Figure 5 As shown, the back support 13, thigh support 14, and calf support 15 can swing, so that the support surface can change its contour to drive the mattress 16 above it to deform synchronously, thereby ensuring that the mattress 16 can be transformed into various postures to meet the user's needs in different scenarios.

[0028] In actual operation, the calf plate 15 is swayably mounted on the rear edge of the thigh plate 14, and the vertical plate 2 is perpendicularly connected to the calf plate 15 and maintains linkage. The mattress 16 is placed on the support plate assembly, with the bottom surface of the mattress 16 in contact with the support plate assembly, and the rear wall of the mattress 16 in contact with the vertical plate 2 mounted on the rear edge of the calf plate 15. This not only provides space for the mattress 16 but also restricts its backward displacement, ensuring that the vertical projection of the mattress 16 coincides with the support plate assembly and guaranteeing the synchronization of the two.

[0029] In actual operation, the vertical plate 2 is detachably installed on the rear edge of the support plate assembly via the connector 3, so that the vertical plate 2 can move synchronously with the support plate assembly and limit the mattress 16. During installation, firstly, the top of the connector 3 is attached and fixed to the vertical plate 2 via the connecting piece 10 to fix the relative position between the vertical plate 2 and the connector 3; then, the sleeve 5 is inserted into the mounting hole 4 from top to bottom, and overlapped at the periphery of the upper port of the mounting hole 4 by the limiting ring 6 to ensure that the inner wall of the mounting hole 4 is covered by the sleeve 5; finally, the vertical plate 2 is installed from top to bottom to the rear edge of the leg plate 15, and the bottom of the connector 3 is vertically inserted into the corresponding sleeve 5.

[0030] After installation, the vertical plate 2 is located above the rear edge of the lower leg plate 15, the middle horizontal part 8 of the connector 3 is horizontally positioned and overlaps the lower leg plate 15, and the lower vertical part 9 of the connector 3 is inserted into the sleeve 5 (e.g., Figure 4 As shown, the connection between the middle horizontal part 8 and the lower leg plate 15 restricts the front-to-back rotation of the top of the connector 3, and the insertion of the lower vertical part 9 into the sleeve 5 further restricts the front-to-back offset of the connector 3. This positions the vertical plate 2, ensuring that it is always vertically positioned above the rear edge of the lower leg plate 15. When the vertical plate 2 is subjected to a horizontal rearward force, a lever arm is formed due to the height difference between the vertical plate 2 and the sleeve 5, resulting in a torsional force acting on the lower vertical part 9. The contact between the middle horizontal part 8 and the lower leg plate 15 effectively counteracts this torsional force, thus protecting the mounting hole 4 and preventing deformation due to localized stress.

[0031] In actual operation, the connector 3 is a Z-shaped tube, including an upper vertical part 7, a middle horizontal part 8, and a lower vertical part 9 formed by integral bending. The upper vertical part 7 is fixed to the vertical plate 2 by fasteners, and the lower vertical part 9 is detachably inserted into the mounting hole 4. When the mattress 16 is installed in place, it presses down on the middle horizontal part 8, so that the lower vertical part 9 is always inserted into the sleeve 5, preventing the connector 3 from detaching upward from the sleeve 5 and ensuring the reliability of the connection between the connector 3 and the leg plate 15. In addition, the front-to-back distance between the vertical plate 2 and the mounting hole 4 is the same as the length of the middle horizontal part 8, so that the vertical plate 2 is located at the rear edge of the support plate assembly. By setting the middle horizontal part 8, a front-to-back positional difference can exist between the upper vertical part 7 and the lower vertical part 9, so that the mounting hole 4 can be opened in the middle of the leg plate 15, ensuring that each section around the mounting hole 4 has a large radial dimension, effectively improving the structural strength of the periphery of the mounting hole 4.

[0032] In actual operation, the rear edge of the support plate assembly has a vertically opened mounting hole 4. The bottom of the connector 3 is inserted into the mounting hole 4, and the top is fixed to the vertical plate 2, so that the vertical plate 2 and the rear edge of the support plate assembly are linked. A sleeve 5 is inserted into the mounting hole 4. The upper end of the sleeve 5 is folded outward to form a limiting ring 6. The sleeve 5 is inserted into the mounting hole 4 and overlaps the periphery of the mounting hole 4 through the limiting ring 6. The bottom of the connector 3 is detachably inserted into the sleeve 5. The length of the sleeve 5 is greater than the depth of the mounting hole 4 to increase the contact area between the sleeve 5 and the bottom of the connector 3. The lower leg plate 15 is usually made of wood and has low hardness, while the sleeve 5 is made of metal and has high hardness. The sleeve 5 receives the force from the connector 3 and distributes it to the periphery of the mounting hole 4 and various areas of the inner wall, thus protecting the mounting hole 4. The force from the connector 3 includes deflection force and horizontal offset force.

[0033] In actual operation, the outer diameter of the sleeve 5 matches the diameter of the mounting hole 4, and the bottom of the connector 3 is tightly inserted into the sleeve 5, which effectively reduces the gap between the outer wall of the sleeve 5 and the inner wall of the mounting hole 4, and between the inner wall of the sleeve 5 and the outer wall of the lower vertical part 9. This can reduce the shaking amplitude of the connector 3 and the vertical plate 2, and also effectively reduce the noise generated by the impact, thus improving the user experience.

[0034] In actual operation, the top of the upper vertical part 7 is provided with an L-shaped connecting piece 10 (such as...). Figure 3 As shown, the connecting piece 10 is attached to the bottom front edge of the vertical plate 2 and is fixedly connected to the bottom rear wall and bottom wall of the vertical plate 2 by fasteners. This provides both vertical support for the vertical plate 2 and front-back limiting, ensuring that the vertical plate 2 remains in an upright position. The connecting piece 10 is fixed to the vertical plate 2 by fasteners.

[0035] In actual operation, the vertical plate 2 is elongated, and there are three connectors 3, which are evenly spaced along the bottom edge of the vertical plate 2. The connectors 3 are located in the middle and on both sides of the bottom edge of the vertical plate 2, which effectively improves the positioning performance of the vertical plate 2 and thus effectively limits the mattress 16 from shifting backward.

[0036] In actual operation, the height of the vertical plate 2 matches the thickness of the mattress 16. This increases the contact area between the limiting surface and the back wall of the mattress 16, effectively dispersing the force and preventing wear on the back wall of the mattress 16 due to localized concentrated force. It also ensures that the top edge of the vertical plate 2 does not protrude from the top surface of the mattress 16, allowing the mattress 16 to conceal the vertical plate 2. The length of the lower vertical section 9 is reduced to provide installation space for the vertical plate 2, and the height of the vertical plate 2 is increased to increase the contact area with the back wall of the mattress 16.
