Description

Technical Field

[0001] The present invention relates to the field of bedding, in particular to a bed frame. Background Art

[0002] The existing bed frame includes a frame body and a support plate assembly disposed on the frame body. The top surface of the support plate assembly forms a support surface for supporting a mattress. The support plate assembly includes a fixed portion fixed to the frame body and a movable portion movable relative to the fixed portion. The movable portion can be movable relative to the fixed portion, so that the contour of the support surface is variable, thereby changing the mattress shape to meet the user's usage needs in different scenarios. A stop bar is provided at the rear edge of the support plate assembly, and a backrest is provided at the front edge of the frame body. The stop bar and the backrest are used to limit the mattress in the front and rear directions, ensuring that the mattress is always located above the support surface and deforms synchronously with the support surface. The existing stop bar is formed by bending a rod-shaped member, including a fixed portion formed by the end and assembled with the rear edge of the support plate assembly, and a limiting portion provided in the middle section. Since the limiting portion is rod-shaped, the contact area between the stop bar and the rear wall of the mattress is small, which not only makes the rear wall of the bed frame prone to local extrusion deformation, affecting the service life of the mattress, but also causes wear on the rear wall of the mattress, affecting the aesthetics. Summary of the Invention

[0003] In order to address the shortcomings of the prior art, the present invention provides a bed frame with a vertical board, in which a vertical board for limiting the backward deviation of the mattress is arranged at the rear edge of the support plate group, effectively increasing the contact area between the vertical board and the rear wall of the mattress, thereby improving the limiting reliability, protecting the rear wall of the mattress, preventing wear, extending the service life of the mattress, and improving the aesthetics.

[0004] The present invention is achieved through the following method: a bed frame with risers, comprising a frame body and a support plate assembly mounted on the frame body, the support plate assembly comprising a fixed portion fixed to the frame body and a movable portion movable relative to the fixed portion, a riser disposed along the width of the support plate assembly at the rear edge thereof, the front wall of the riser forming a stopper surface against which the rear wall of the mattress abuts, thereby preventing wear of the rear wall of the mattress. The riser disposed at the rear edge of the support plate assembly effectively increases the contact area between the riser and the rear wall of the mattress, utilizing the riser to abut against the rear wall of the mattress and limit rearward displacement of the mattress, thereby improving the reliability of the stopper and protecting the rear wall of the mattress from wear, thereby extending the life of the mattress and enhancing its aesthetics.

[0005] Preferably, the riser is removably mounted to the rear edge of the support plate assembly via a connector, allowing the riser to move synchronously with the support plate assembly and restrain the mattress. The connector connects the riser to the support plate assembly, facilitating assembly and disassembly of the riser, improving assembly efficiency, and securing the riser, ensuring it effectively prevents the mattress from shifting backwards and remains in place, deforming synchronously with the support surface.

[0006] Preferably, a vertical mounting hole is provided at the rear edge of the support plate assembly. The bottom of the connector is inserted into the mounting hole, and the top is fixedly connected to the riser, thereby aligning the riser with the rear edge of the support plate assembly. The vertical axis of the mounting hole facilitates vertical insertion of the bottom of the connector and facilitates assembly and disassembly. The weight of the connector and riser is also used to prevent the connector from upwardly dislodging from the mounting hole, ensuring a secure connection. The connector also effectively resists the horizontal force generated by the rearward displacement of the mattress, effectively improving the reliability of the position limit.

[0007] Preferably, a sleeve is inserted into the mounting hole. The upper edge of the sleeve is folded outward to form a retaining ring. The sleeve is inserted into the mounting hole and overlaps the edge of the mounting hole through the retaining ring. The bottom of the connector is removably inserted into the sleeve. The sleeve is inserted into the mounting hole, and the bottom of the connector is inserted into the sleeve. The sleeve disperses the forces acting on the connector to various areas of the inner wall of the mounting hole, preventing deformation of the mounting hole edge due to concentrated force. This ensures that the bottom of the connector always maintains an upright position, thereby ensuring that the riser can be reliably positioned at the preset position and limiting the backward displacement of the mattress. The retaining ring can overlap the upper edge of the mounting hole to vertically limit the sleeve and prevent it from falling out of the mounting hole. The support plate assembly is typically made of wood, which has a low hardness and is easily deformed by localized force. The sleeve is provided to distribute the forces 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, thereby dispersing the force by increasing the contact area between the two, thereby maintaining the contour 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, and the fit is improved by reducing the gap between the two, thereby improving the force diffusion effect.

[0010] Preferably, the bottom of the connector is tightly inserted into the sleeve to reduce shaking of the connector, thereby preventing the vertical plate from shifting, which not only plays a role in accurately positioning the mattress, but also effectively reduces noise.

[0011] Preferably, the connector is a Z-shaped tubular fitting, comprising an upper vertical portion, a middle horizontal portion, and a lower vertical portion formed by integral bending. The upper vertical portion is fixed to the vertical plate via fasteners, and the lower vertical portion is removably inserted into the mounting hole. The connector utilizes the middle horizontal portion to connect the upper and lower vertical portions, which not only ensures the connector has good structural strength, but also utilizes the middle horizontal portion to mate with the top surface of the support plate assembly, effectively reducing the possibility of the connector deflecting backward due to top force, thereby improving positioning reliability. The middle horizontal portion is pressed under the mattress, and the weight of the mattress is used to vertically position the connector, ensuring that the lower vertical portion is always inserted into the sleeve.

[0012] Preferably, an L-shaped connecting piece is provided at the top of the upper vertical portion, and the connecting piece is in contact with the front edge of the bottom of the vertical plate and fixed by fasteners. The connecting piece is tightly fitted with 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 limits the vertical plate in the front and rear directions, ensuring that the force acting on the vertical plate can be transmitted to the connecting piece through the connecting piece, and then borne by the supporting plate group.

[0013] Preferably, the distance between the vertical plate and the mounting hole in the fore-aft direction is the same as the length of the middle transverse portion, so that the vertical plate is positioned at the rear edge of the support plate assembly. The middle transverse portion is used to shift the mounting hole forward, ensuring that the perimeter of the mounting hole has a thickness that meets usage requirements, thereby increasing the structural strength of the perimeter of the mounting hole and ensuring that the lower vertical portion of the connector can be effectively positioned and maintained in an upright position.

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

[0015] Preferably, the height of the vertical board matches the thickness of the mattress, which not only increases the area of ​​contact between the limiting surface and the back wall of the mattress, effectively disperses the force, and prevents the back wall of the mattress from being worn due to local concentrated force, but also ensures that the top edge of the vertical board is not exposed on the top surface of the mattress, and uses the mattress to hide the vertical board.

[0016] Preferably, the fixed portion includes a lumbar support plate and a hip support plate fixedly connected in a front-to-back direction, and the movable portion includes a back support plate, a thigh support plate, and a calf support plate, with the vertical plate mounted on the rear edge of the calf support plate. The back support plate, lumbar support plate, hip support plate, thigh support plate, and calf support plate are arranged in sequence from front to back and form a support surface for supporting the mattress. The vertical plate is mounted on the rear edge of the calf support plate, which not only reserves space for the mattress but also serves to limit the mattress from deflecting 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 maintain a linkage. The vertical plate and the calf plate are linked and always maintain a perpendicular relationship, ensuring that the calf plate and the vertical plate can respectively contact the rear portion of the bottom wall and the rear wall of the mattress, effectively improving the positioning effect of the mattress.

[0018] The beneficial effects of the present invention are as follows: a vertical plate is arranged at the rear edge of the support plate group, which effectively increases the contact area between the vertical plate and the rear wall of the mattress. The vertical plate is used to contact the rear wall of the mattress and limit the backward deviation of the mattress, which not only improves the limiting reliability, but also protects the rear wall of the mattress, prevents wear, extends the service life of the mattress, and improves the aesthetics.

DETAILED DESCRIPTION

[0025] The essential features of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0026] like Figure 1 and 2The bed frame with risers shown includes a frame 1 and a support plate assembly mounted on the frame 1. The support plate assembly includes a fixed portion fixed to the frame 1 and a movable portion movable relative to the fixed portion. A riser 2 is provided at the rear edge of the support plate assembly along its width. The front wall of the riser 2 forms a limiting surface against which the rear wall of the mattress 16 contacts, thereby preventing wear on the rear wall of the mattress 16. Providing the riser 2 at the rear edge of the support plate assembly effectively increases the contact area between the riser 2 and the rear wall of the mattress 16. The riser 2 contacts the rear wall of the mattress 16 and limits the rearward displacement of the mattress 16, thereby improving the reliability of the limit and protecting the rear wall of the mattress 16 from wear, extending the service life of the mattress 16, and enhancing its aesthetics.

[0027] In actual operation, the fixed part includes a lumbar support plate 11 and a hip support plate 12 fixed in the front-to-back direction, 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 swingably connected to the front edge of the lumbar support plate 11, and the thigh plate 14 is swingably connected to the rear edge of the hip support plate 12. The back support plate 13, the lumbar support plate 11, the hip support plate 12, the thigh plate 14 and the calf plate 15 are arranged in sequence from front to back and form a supporting surface for supporting the mattress 16 (such as Figure 5 As shown), the back support plate 13, thigh plate 14 and calf plate 15 can swing, so that the supporting surface can drive the mattress 16 above it to deform synchronously by changing its contour, thereby ensuring that the mattress 16 can be deformed into various postures to meet the user's usage needs in different scenarios.

[0028] In actual operation, the calf board 15 is swingably mounted on the rear edge of the thigh board 14. The vertical board 2 and the calf board 15 are perpendicularly connected and maintain a coordinated motion. The mattress 16 is placed on the support board assembly, with the bottom surface of the mattress 16 in contact with the support board assembly and the rear wall of the mattress 16 in contact with the vertical board 2 mounted on the rear edge of the calf board 15. This not only reserves space for the mattress 16 but also limits its rearward displacement, ensuring that the vertical projection of the mattress 16 coincides with the support board assembly, ensuring the coordinated synchronization between the two.

[0029] In practice, the riser 2 is detachably mounted to the rear edge of the support plate assembly via the connector 3, allowing it to move synchronously with the support plate assembly and limit the position of the mattress 16. During installation, the top of the connector 3 is first affixed to the riser 2 via the connecting piece 10, thereby fixing the relative position between the riser 2 and the connector 3. Next, the sleeve 5 is inserted from top to bottom into the mounting hole 4 and overlapped around the upper end of the mounting hole 4 via the retaining ring 6, ensuring that the inner wall of the mounting hole 4 is covered by the sleeve 5. Finally, the riser 2 is mounted from top to bottom to the rear edge of the calf plate 15, with the bottom of the connector 3 vertically inserted into the corresponding sleeve 5.

[0030] After installation, the vertical plate 2 is located above the rear edge of the calf plate 15, the middle transverse portion 8 of the connecting member 3 is horizontally arranged and overlapped on the calf plate 15, and the lower vertical portion 9 of the connecting member 3 is inserted into the sleeve 5 (such as Figure 4 As shown, the middle transverse portion 8 and the calf plate 15 interfere with each other to prevent the top of the connector 3 from deflecting forward and backward. Furthermore, the lower vertical portion 9 and the sleeve 5 engage to prevent the connector 3 from shifting forward and backward, thereby positioning the riser 2 and ensuring that it is always positioned vertically above the rear edge of the calf plate 15. When the riser 2 is subjected to a horizontal rearward force, a moment arm is formed due to the height difference between the riser 2 and the sleeve 5, which in turn generates a torsional force acting on the lower vertical portion 9. The interference between the middle transverse portion 8 and the calf plate 15 effectively counteracts this torsional force, thereby protecting the mounting hole 4 from deformation due to localized force.

[0031] In actual operation, the connector 3 is a Z-shaped tube, comprising an upper vertical portion 7, a middle horizontal portion 8, and a lower vertical portion 9 formed by integral bending. The upper vertical portion 7 is fixed to the vertical plate 2 by fasteners, and the lower vertical portion 9 is pluggable and inserted into the mounting hole 4. The mattress 16 is installed in place and presses the middle horizontal portion 8 downward, so that the lower vertical portion 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 calf 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 portion 8, so that the vertical plate 2 is set at the rear edge of the support plate group. By providing the middle horizontal portion 8, a front-to-back position difference between the upper vertical portion 7 and the lower vertical portion 9 can be achieved, so that the mounting hole 4 can be opened in the middle of the calf plate 15, ensuring that each section around the mounting hole 4 has a large radial dimension, effectively improving the structural strength of the mounting hole 4.

[0032] In actual operation, a vertical mounting hole 4 is provided at the rear edge of the support plate assembly. The bottom of the connector 3 is inserted into the mounting hole 4, and the top is fixedly connected to the riser 2, so that the riser 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 retaining ring 6. The sleeve 5 is inserted into the mounting hole 4 and overlaps the periphery of the mounting hole 4 through the retaining ring 6. The bottom of the connector 3 is pluggable and 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 calf plate 15 is typically made of wood and has a relatively low hardness. The sleeve 5 is made of metal and has a relatively high hardness. The sleeve 5 receives the force applied by the connector 3 and distributes it to the periphery of the end of the mounting hole 4 and various areas of the inner wall, thereby protecting the mounting hole 4. The force applied by the connector 3 includes deflection force and horizontal displacement force.

[0033] In actual operation, the outer wall diameter of the sleeve 5 matches the diameter of the mounting hole 4, and the bottom of the connector 3 is tightly inserted in the sleeve 5, effectively reducing 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. It can not only reduce the shaking amplitude of the connector 3 and the vertical plate 2, but also effectively reduce the noise generated by impact, thereby improving the user experience.

[0034] In actual operation, the top of the upper vertical portion 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 riser 2 and is fixed to the connecting piece 3 via fasteners. The connecting piece 3 is attached to the bottom rear wall and bottom wall of the riser 2, providing both vertical support for the riser 2 and limiting its forward and backward position, ensuring that the riser 2 remains upright. The connecting piece 10 is fixed to the riser 2 via fasteners.

[0035] In actual operation, the riser 2 is long and strip-shaped, and the number of connectors 3 is three, equidistantly spaced along the bottom edge of the riser 2. The connectors 3 are disposed in the middle and on both sides of the bottom edge of the riser 2, effectively improving the positioning of the riser 2 and thereby effectively limiting the backward displacement of the mattress 16.

[0036] In actual operation, the height of the riser 2 matches the thickness of the mattress 16. This not only increases the area of ​​contact between the limiting surface and the rear wall of the mattress 16, effectively dispersing the applied force and preventing wear of the rear wall of the mattress 16 due to localized concentrated force, but also ensures that the top edge of the riser 2 is not exposed above the top surface of the mattress 16, thereby utilizing the mattress 16 to conceal the riser 2. By reducing the length of the lower vertical portion 9, space is reserved for the installation of the riser 2, and by increasing the height of the riser 2, the contact area with the rear wall of the mattress 16 is increased.
