Description

Technical Field

[0001] The present invention relates to a piece of furniture, in particular to a bed frame structure and a three-dimensional soft bed with a backrest having the bed frame structure. Background Art

[0002] The frame structure of a soft bed is typically constructed from spliced ​​wood, with soft packaging material covering the timber frame. Curved shapes are often created by cutting a single piece of wood, or by forming it through collision and bending to create the desired frame structure.

[0003] In traditional bed frames, adjacent side panels are connected and secured using angle brackets, typically located on the inner perimeter of the bed frame. This means that by installing a right-angled angle bracket between the inner sides of two adjacent side panels, the two panels can be joined and secured. However, when the side panels are wide, the joining of the two side panels creates a large seam between them. Fixing only along the inner perimeter of the bed frame is insufficient to maintain structural stability.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0008] The present invention is further configured such that the end surface portion is provided with a groove, the fixing piece is embedded in and fixed in the groove, and the groove is passed through toward the inner circumference of the bed frame and forms a through opening.

[0009] The present invention is further configured such that the fixing member is fixedly connected to a hook, and bayonet holes are respectively provided on both sides of the connecting member. The bayonet holes and the bayonet hooks are arranged in a one-to-one correspondence and can be locked to each other.

[0010] The present invention is further configured such that the end of the hook away from the fixing member is inclined toward the outer periphery of the bed frame; the connecting member has an end facing the through-opening, and a support portion is fixedly installed at the inner side corner of the adjacent side enclosure, and the support portion and the end of the connecting member are fixed by bolts.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] This embodiment discloses a bed frame structure, referring to Figure 1-Figure 7 As shown, the bed frame 100 includes four side panels 1, which together form a frame-shaped structure. A bed backrest 2 is fixedly mounted on the side panels 1 facing the head of the bed, serving as the headboard structure. In this embodiment, the bed backrest 2 is an arc-shaped structure, with its edges forming a roughly elliptical shape.

[0034] The four side panels 1 are fixedly connected to form a roughly quadrilateral structure. An inclined end surface portion 15 is provided at each end of the side panel 1. When installed, the end surfaces 15 of adjacent side panels 1 abut against each other, allowing the two side panels 1 to be spliced ​​perpendicularly to each other.

[0035] In a conventional bed frame 100, adjacent side panels 1 are connected and secured using angle brackets. These brackets are typically installed on the inner periphery of the bed frame 100. Specifically, a right-angled angle bracket is installed between the inner surfaces 13 of two adjacent side panels 1 to secure them together. However, when the side panels 1 are wide (i.e., the end surfaces 15 of the side panels 1 are large), a large seam forms between the adjacent side panels 1 when they are joined. Fixing the bed frame 100 only along its inner periphery is insufficient to maintain structural stability.

[0036] Reference Figure 1-Figure 3As shown, in this embodiment, the side panels 1 are made of wood and are covered with soft packing material. The side panels 1 have a certain width, so that the area of ​​the end surface 15 at the connection between the two side panels 1 will also be increased accordingly.

[0037] In this embodiment, the side panel 1 has an upper side 11, a lower side 12, an inner side 13, and an outer side 14. Adjacent side panels 1 are fixedly connected by a first connecting frame 3 and a second connecting frame 4. The first connecting frame 3 and the second connecting frame 4 form two connecting structures, which are respectively installed on the upper and lower sides of the inner circumference of the bed frame 100 to form a fixed connection.

[0038] Reference Figure 3 、 Figure 4 As shown, the connecting frame 1 3 includes an upper connecting piece 31 and a side connecting piece 1 32, which are integrally connected. The upper connecting piece 31 is arranged along the seam between the upper sides 11 of adjacent side panels 1 and is fixedly connected to the upper sides 11 of the two side panels 1.

[0039] Two rows of upper connecting holes 311 are provided on the upper connecting plate 31 , and the two rows of upper connecting holes 311 correspond to two adjacent side panels 1 respectively. The upper connecting plate 31 and the side panels 1 can be connected and fixed by bolts, thereby connecting and fixing the upper side surfaces 11 of the two side panels 1 .

[0040] The side connecting piece 32 is bent into a right-angle structure, and the upper edge of the side connecting piece 32 is welded and fixed to the upper connecting piece 31 to form an integrated structure; during installation, the side connecting piece 32 is installed at the inner corners of the two side enclosures 1, and is respectively fitted and fixed to the inner side surfaces 13 of the two side enclosures 1.

[0041] Side connecting holes 321 are provided on both sides of the bending portion of the side connecting piece 32, and the side connecting piece 32 can be connected and fixed to the side enclosure 1 by bolts, thereby connecting and fixing the upper side surfaces 11 of the two side enclosures 1.

[0042] Reference Figure 3 、 Figure 4As shown, the second connecting frame 4 includes a lower connecting piece 41 and a second side connecting piece 42, which form an integrally connected structure. The lower connecting piece 41 follows the corner contour of the adjacent side panel 1, forming a flat plate-like structure. The lower connecting piece 41 is supported by the lower side surface 12 of the side panel 1. The second side connecting piece 42 is bent at a right angle, and the lower edge of the second side connecting piece 42 is welded to the lower connecting piece 41 to form an integral structure. Furthermore, a portion of the lower connecting piece 41 extends to the inner periphery of the bed frame 100, forming a reinforced connection 43 between the bent edges of the second side connecting piece 42. The second side connecting piece 42 can form a support structure within the inner periphery of the bed frame 100, providing support for the mattress or other components within the inner periphery of the bed frame 100.

[0043] The lower connecting piece 41 has several lower connecting holes 411 aligning with the lower sides 12 of two adjacent side panels 1, allowing bolts to securely connect the lower sides 12 of the two side panels 1. A second side connecting piece 42 is securely connected to the inner sides 13 of the two side panels 1. Second side connecting holes 421 are defined on both sides of the bent portion of the second side connecting piece 42, allowing bolts to securely connect the second side connecting piece 42 to the side panels 1, thereby securing the upper sides 11 of the two side panels 1.

[0044] In addition, a foot frame is fixedly connected to the lower side of the lower connecting piece 41 of the connecting frame 2 4, which can serve as a support for the entire bed frame and can stably place the bed frame on the ground.

[0045] In this embodiment, the outer side surface 14 of the side connecting piece 1 32 is a three-dimensional, arc-like structure, forming an arc-shaped transition from top to bottom. Because the outer side surface 14 is directly exposed to the outside of the bed frame, it is impossible to directly install a corner bracket structure on the outer side surface 14. As a result, the connection between two adjacent side panels 1 cannot be connected and fixed in all four directions. Furthermore, due to the large inner and outer widths of the side panels 1, the end surfaces 15 of the side panels 1 have a large contact area and a long seam length, which can easily lead to instability at the seam of the side panels 1.

[0046] Furthermore, in this embodiment, the end face portions 15 of adjacent side panels 1 are connected and fixed by a connecting mechanism, and a plurality of connecting and fixing points can be formed between the end face portions 15 by the connecting mechanism, thereby avoiding the undesirable situation of seam expansion on the outer sides of the two side panels 1, and further maintaining the structural stability of the bed frame 100.

[0047] Reference Figure 4-Figure 6As shown, the connection mechanism includes a connector 6 and two fixing members 5. The two fixing members 5 are respectively fixedly mounted on the end surfaces 15 of adjacent side panels 1, with the connector 6 positioned between the two fixing members 5. The connector 6 cooperates with the two fixing members 5 to form multiple connection points, enabling the two fixing members 5 to be connected and fixed, thereby connecting and fixing the end surfaces 15 of the two side panels 1 together. Furthermore, the connection points between the connector 6 and the fixing members 5 are arranged along the inner and outer width of the bed frame 100, with the outermost connection point located near the outer side surface 14. This creates multiple connection points between the end surfaces 15 to maintain the stability of the connection structure.

[0048] Furthermore, a groove 16 is provided on the end surface portion 15, and the fixing member 5 is a sheet-like structure, which can be embedded in and fixed in the groove 16, and can give way to each other between the two end surface portions 15, so that the two end surface portions 15 can be pressed and fitted flatly; and the grooves 16 of the two end surface portions 15 are positioned relative to each other, and the connecting member 6 can also be embedded in the grooves 16 on both sides when installed, and the connecting member 6 can also give way to allow the connecting mechanism to be basically embedded.

[0049] The groove 16 extends through the inner circumference of the bed frame 100 and has a through hole 161. The adjusting bolt 7 can partially pass through the through hole 161 and can form a linkage with the connecting member 6 in the groove 16 to lock and adjust the connection member 6 and the fixing member 5.

[0050] Reference Figure 4-Figure 6 As shown, a hook 51 is fixedly connected to the opposite side of the fixing member 5, and both sides of the connecting member 6 face the two fixing members 5 and are provided with a bayonet 61. The bayonet 61 is arranged one-to-one with the hook 51, and can be locked with each other to clamp the connecting member 6 and the fixing member 5 together.

[0051] Reference Figure 7 As shown, in this embodiment, one end of the hook 51 is fixed to the fixing member 5, while the other end extends obliquely toward the connecting member 6 and is tilted toward the outer periphery of the bed frame 100. During connection, the hook 51 can be inserted into the notch 61, forming a mutually locking structure. Furthermore, the hook 51 forms an arc-shaped tilt, and as the hook 51 and notch 61 move toward the interlocking direction, they gradually form a tightening effect.

[0052] In this embodiment, the connecting member 6 has an end head 62 facing the through-hole 161 , and a threaded hole is provided at the end head 62 , and the threaded hole is threadably matched with the corresponding bolt 7 .

[0053] A support portion 8 is fixedly installed at the corner of the inner side surface 13 of the adjacent side enclosure 1 , and the support portion 8 and the end 62 of the connecting member 6 are locked and fixed by bolts 7 .

[0054] During installation, bolt 7 is inserted from the inner circumference of bed frame 100 through the through hole of support portion 8 and is threadedly connected to end 62 of connector 6. By tightening bolt 7, connector 6 can be adjusted relative to fixing member 5, and the connecting member 6 and fixing member 5 can have a certain adjustment range, and the hook 51 and the latch 61 are locked and fixed together.

[0055] Reference Figure 6 、 Figure 7 As shown, in this embodiment, when the bolt 7 is locked and adjusted, it will drive the connecting member 6 to move toward the inner circumference of the bed frame 100, so that the bayonet 61 on both sides of the connecting member 6 can be clamped and fixed with the hook 51 of the fixing member 5 on both sides, and exert a force on the end surface portions 15 on both sides in the direction of closing each other, so as to improve the connection stability and tightness between the side panels 1.

[0056] Furthermore, in this embodiment, two sets of connecting mechanisms are provided between adjacent side panels 1, distributed vertically. Furthermore, the fixing members 5 and connectors 6 are strip-shaped and arranged horizontally, forming multiple connection points between adjacent end panels 15. Several sets of hooks 51 and latches 61 are arranged along the length of the fixing members 5 and connectors 6, forming multiple connection points along the inner and outer circumference of the bed frame 100 to maintain the stability of the connection between the two end panels 15.

[0057] Two sets of support sections 8 are also provided relative to the ground. The upper support section 8 is integrally connected to the connecting frame 1 3, while the lower support section 8 is integrally connected to the connecting frame 2 4. The side connecting piece 1 32 is a right-angled structure, with support sections 1 33 formed at the corners. This support section 1 33 has a through-hole 1 331, meaning that the middle bend of the side connecting piece 1 32 serves as support section 1 33. The side connecting piece 2 42 is a right-angled structure, with support sections 2 44 formed at the corners. This support section 2 44 has a through-hole 2 441, meaning that the middle bend of the side connecting piece 2 42 serves as support section 2 44.

[0058] Two sets of bolts 7 connect the first and second connecting frames 3 and 4 to the connecting mechanism. During assembly, the locking structure of the end face 15 is connected to the first and second connecting frames 3 and 4 to form a single unit, thereby enhancing the stability of the overlapped end face 15. During the tightening of the two sets of bolts 7, the two side panels 1 are overlapped and fixed, stably connecting and fixing the two side panels 1 to form a more stable, integrated structure.

[0059] This embodiment also discloses a three-dimensional backrest, including the above-mentioned bed frame structure. In the bed frame structure, the bed frame 100 also includes a bed backrest 2, which is fixedly installed on the upper part of one of the side panels 1 and serves as the rear backrest of the bed frame 100.

[0060] Reference Figure 8 、 Figure 9 In this embodiment, the bed backrest 2 includes a connecting base 21 and a grid-like frame 22. The connecting base 21 is located at the bottom of the bed backrest 2 and is directly fixed to the upper side of the side panel 1. The grid-like frame 22 is fixed to the upper side of the connecting base 21. The grid-like frame 22 is formed by a plurality of crisscrossing wooden rods, which are spliced ​​together to form a grid-like structure. The overall outline of the grid-like frame 22 is similar to an elliptical structure.

[0061] An upper curved rod 23 is fixedly mounted on the upper side of the grid-like frame 22. The upper curved rod 23 is bent into an arc-shaped structure. On either side of the grid-like frame 22 are elliptical side curved portions 24. A transition portion 25 is formed between the side curved portions 24 and the ends of the upper curved rod 23. The transition portion 25 comprises a plurality of transition blocks 251. These transition blocks 251 have a matching block-like structure, which can be wedge-shaped. Multiple transition blocks 251 are sequentially spliced ​​to form an arc-shaped structure that adapts to the angle. This allows for a smooth, continuous arc to form between the upper curved rod 23 and the side curved portions 24, creating a curved structure for the entire bed backrest 2.

[0062] Furthermore, to enhance the structural stability of the side edges of the bed backrest 2, a plurality of back support plates 26 can be fixedly mounted on the back of the side curved portions 24. The back support plates 26 are in the form of horizontal strips, and are arranged in sequence to support the rear side of the bed backrest 2, thereby enhancing the overall strength and stability of the bed backrest 2.

[0063] Further, based on the above embodiment, referring to Figure 10 、 Figure 11 , further optimizing the locking structure between the fixing member 5 and the connecting member 6. In this embodiment, several sets of limiting sleeves 9 are installed inside the connecting member 6. The limiting sleeves 9 are installed at both ends of the bayonet 61 and extend the bolt 7. The bolt 7 can extend to the limiting sleeves 9, which can further limit the hook 51 at the bayonet 61.

[0064] Specifically, the limiting sleeve 9 includes a fixed section 1 91, a fixed section 2 92 and two elastic limiting plates 93. The fixed section 1 91 and the fixed section 2 92 are installed along the length direction of the bolt 7 and are fixedly installed on both sides of the bayonet 61 of the connecting member 6. The two ends of the elastic limiting plate 93 are respectively connected to the fixed section 1 91 and the fixed section 2 92, and the two limiting plates 93 are respectively opposite to the bayonet 61 on both sides.

[0065] The elastic limiting piece 93 can be made of an elastic metal sheet or plastic sheet, and has an outer side surface 932 facing the outside of the bayonet 61 and an inner side surface 931 facing the inside. The inner side surface 931 is an arc-shaped raised structure, and the minimum distance between the two inner side surfaces 931 is smaller than the outer diameter of the bolt 7. When the bolt 7 is installed, it can extend between the two inner side surfaces 931, exerting outward pressure on the two inner side surfaces 931, so that the elastic limiting piece 93 can be elastically deformed toward the outer bayonet 61. The outer side surface 932 of the elastic limiting piece 93 can counteract the hook 51 that is inserted into the bayonet 61, thereby generating a mutual extrusion force between the limiting sleeve 9 and the hook 51, and exerting a small elastic pressure on the hook 51. The hook 51 is embedded between the elastic limiting piece 93 and the inner side wall of the connector 6 to squeeze and limit the hook 51, thereby improving the clamping stability between the hook 51 and the bayonet 61.

[0066] By forming a mutually clamping and limiting structure between the bolts 7 and the limiting sleeves 9, the stability of the locking state of the two can be further improved, and the stable connection structure of the bed frame 100 can be maintained.

[0067] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
