Description

Technical Field

[0001] This invention relates to a bed structure, and more particularly to a fixed structure that allows for quick and stable installation and fixation of the bed board and bed frame. Prior Technology

[0002] The bed is an indispensable piece of furniture in our lives, but it is large and heavy. Manufacturers need to disassemble the bed board, bed frame, and related products into smaller parts (assemblies) that can be reassembled after delivery to the consumer. Therefore, the connection structure between the various components is crucial. Products with easy-to-implement and sturdy connections are more favored by users.

[0003] In existing technologies, two common connection structures are used between the bed slats and side panels. The first uses corner connectors for assembly, requiring multiple screws for tightening, resulting in a cumbersome, labor-intensive, and inefficient assembly process. The second is a snap-fit ​​connection, which is relatively convenient for assembling the bed slats and side panels. However, this connection method concentrates the effective connection points at the snap-fit ​​points, reducing structural strength. Furthermore, the snap-fit ​​points represent a rigid connection between the bed slats and side panels, which can easily generate noise, especially during bed frame swaying.

[0004] To address the aforementioned problems in existing technologies, Mr. Fujin filed U.S. Patent No. 2024 / 0341490A1, abandoning the spiral locking element and replacing it with a detachable interlocking method, which installs multiple bed slats between two bed side beams, enabling rapid assembly of a stable bed frame. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention employs an interlocking structure design, which reduces the number of screw locking components while achieving rapid assembly and stable positioning between the bed board and the bed frame.

[0006] To achieve the above objectives, the bed of the present invention includes: a bed frame; multiple side rods disposed on the bed frame; a bed board; multiple fixing components disposed on the back of the bed board, the fixing components having a U-shaped structure, which can cover the side rods and guide the bed board to slide along the length direction of the side rods to the installation position for interlocking; and a fastener for positioning the fixing components on the side rods, so that the bed board is installed on the bed frame.

[0007] In a preferred embodiment, the fixing component includes: a main fixing member, which is a U-shaped metal structure that can cover the side rod and guide the bed board to slide along the length direction of the side rod.

[0008] In a preferred embodiment, the fixing component further includes: a secondary fixing member, which is a U-shaped non-metallic structure and is attached to the inner side of the main fixing member. The secondary fixing member covers the side rod and can guide the bed board to slide along the length of the side rod, thereby reducing noise.

[0009] In a preferred embodiment, the side rod protrudes with a fixing pin; the main fixing member forms a positioning groove, and the positioning groove and the fixing pin are combined to form an interlocking structure, thereby terminating the travel of the bed board sliding on the side rod.

[0010] In a preferred embodiment, the secondary fastener forms a positioning groove to allow the retaining pin to pass through.

[0011] In a preferred embodiment, the main fixing member forms a fixing hole, through which the fastener passes and is fixed to the side rod.

[0012] In a preferred embodiment, the secondary fastener forms a notch to allow the fastener to pass through. Simple Explanation of the Diagram

[0014] In Figure 1, a preferred embodiment of the present invention shows a bed 10, the front end of which typically supports the user's head, also known as the head end; and the rear end of which typically supports the user's feet, also known as the foot end. Between the two ends of the bed 10, there are, but are not limited to, a bed frame 11 and multiple bed boards.

[0015] In this embodiment, the bed frame 11 includes a base (unnumbered) and two side rods. The base has four legs (unnumbered) located at the four corners of the base to contact a support surface resembling the ground or floor, and to stably support the load of the entire bed 10.

[0016] Depending on the size of the bed 10, a lifting unit (not labeled) or support rod (not shown) that can be interchanged is configured and installed between the base and the two side rods.

[0017] The lifting unit is a height adjustment function that converts electrical energy into potential energy for length extension, driving the side rod to rise or fall in the height of the base.

[0018] Each support rod is not height-adjustable, and the support rod maintains a single height on the base.

[0019] As shown in Figures 14 and 15, in this embodiment, the side rod 22 consists of a joint unit 50, a baffle 51, a first tube 52, and a second tube 53. The joint unit 50 is disposed at the opposite ends of the first tube 52 and the second tube 53, supporting the side rod 22 to move back and forth between an extended position and a folded position.

[0020] In the unfolded position, the first tube 52 and the second tube 53 extend in a straight line, so that the side rod 22 maintains its full length.

[0021] In the folded position, the first tube 52 is placed side by side with the second tube 53, reducing the length of the side rod 22.

[0022] Furthermore, the baffle 51 is partially welded to the first tube 52, with the remaining portion extending beyond the first tube 52, thus limiting the second tube 53 to be an extension of the first tube 52. Therefore, the baffle 51 becomes the endpoint of the side rod 22 in its unfolded state. If necessary, the baffle 51 can be locked together with the second tube 53 (see Figure 10).

[0023] In some embodiments, there are neither joint units nor baffles. The side rod 22 is a one-piece straight tube, which is also within the scope of this invention.

[0024] As can be easily understood from Figures 7, 10, 12, 14, and 15, two fixing pins 60 are provided on the side rod 22 and located on both sides of the joint unit 50. In other words, the first tube 52 and the second tube 53 each have one fixing pin 60, and the two ends of the fixing pin 60 protrude from both sides of the first tube 52 or the second tube 53.

[0025] Looking back at Figure 1, the bed frame 11 connects to each of the bed boards, and its height can be raised or lowered to change the height of each bed board on the bed frame 11. To describe the connection relationship in detail, each of the bed boards is defined as: front bed board 12, rear bed board 13, and middle bed board 14.

[0026] As shown in Figure 2, the front bed board 12 stands vertically on the bed frame 11 and is adjacent to the front end (i.e., the head end) of the bed. The side facing the left side of Figure 2 is the front of the front bed board 12, and the other side is defined as the back side 20 of the front bed board 12, which faces the bed frame 11 and is connected to a bed board frame 27.

[0027] Two connecting rods 26 are located above and below the bed frame 27. The connecting rod 26 below the bed frame 27 faces the back 20 of the front bed board 12. The connecting rod 26 above the bed frame 27 extends beyond the perimeter edge of the front bed board 12. The two connecting rods 26 are parallel, and each connecting rod 26 intersects with the side rod 22.

[0028] Each connecting rod 26 has a fixing component 21 at both ends. The two fixing components 21 of the lower connecting rod 26 are each close to a hole (unlabeled) on the side rod 22. The two fixing components 21 of the upper connecting rod 26 are away from the side rod 22. Therefore, each fixing component 21 is located at one of the four corners of the bed frame 27.

[0029] Referring to Figure 6, the front bed board 12 rotates clockwise toward the bed frame 11. At this moment, the bed board frame 27 also moves in the same direction, causing the connecting rod 26 below it to guide the fixing assembly 21 into the side rod 22. Simultaneously, the connecting rod 26 above the bed board frame 27 rotates toward the bed frame 11.

[0030] In Figure 7, the upper and lower connecting rods 26 intersect the side rods 22, causing the front bed board 12 to lie flat on the bed frame 11. At the same time, the fixing assembly 21 spans the side rods 22. As indicated by arrow 15, force is applied to the front bed board 12, causing the bed board frame 27 to slide along the direction of the bed frame 11 to the installation position.

[0031] As shown in Figure 3, the fixing component 21 has a U-shaped structure design, which is detachable and spans the side bar. In this embodiment, the fixing component 21 uses a fastener 25 to connect a main fixing member 23 and a secondary fixing member 24 together.

[0032] As can be clearly seen from Figures 4 and 8, the main fastener 23 includes: a metal plate 30, two side plates 31, two outward expansions 32, two positioning grooves 33, and a connecting hole 34.

[0033] The metal sheet 30 is the middle part of the metal material. Both the metal sheet and the connecting rod 26 are rectangular metal structures. They are welded together in an interlaced manner along their long sides, so that the main fixing part 23 is firmly attached to the connecting rod 26.

[0034] The mating hole 34 is formed in the center of the metal sheet 30 for the fastener 25 to pass through, such as a rivet, bolt, or rivet. A notch (unnumbered) of the connecting rod 26 is opposite the mating hole 34, passing over the portion of the fastener 25 that protrudes from the mating hole 34.

[0035] The two side panels 31 are made of metal and are bent and stand on both sides of the metal sheet 30, giving the main fixing member 23 a U-shaped structure. The main fixing member 23 is made of metal and provides rigid support, realizing the guiding function of covering the side rod 22. When the main fixing member 23 spans the outside of the side rod 22, the two side panels 31 are located on both sides of the side rod 22, guiding the bed board frame 27 to slide along the direction of the bed frame 11.

[0036] The outward expansion 32 is located at the end of the side plate 31 and extends outward at an angle. The distance between the two outward expansions 32 becomes narrower as they approach the metal plate 30, easily guiding the side rod 22 between the two side plates 31.

[0037] The positioning groove 33 is formed on the edge of the side piece 31. In response to the displacement of the main fixing member 23, it can receive the two ends of the fixing pin 60 extending from the side rod 22, forming an interlocking structure. Because the interlocking structure prevents the side piece 31 from continuing to move, the fixing pin 60 becomes the end point of the sliding stroke, which can be defined as the installation position, allowing the front bed plate 12 to remain stationary on the bed frame 11.

[0038] In addition, the main fastener 23 also has a fixing hole 35, which is pre-set between the short side of the metal sheet 30 and the connecting hole 34.

[0039] As shown in Figures 7 and 9, the fixing hole 35 is aligned with the hole of the side rod 22 (see Figure 2). Other fasteners 29 pass through the fixing assembly 21 to lock the front bed plate 12 onto the bed frame 11. The interlocking structure design requires only two (or even a single) fasteners 29 to allow the front bed plate 12 to be quickly assembled onto the bed frame 11 and achieve a stable positioning effect.

[0040] As can be clearly seen from Figures 3, 5, and 7, the fastener 24 includes: a non-metallic piece 40, two side pieces 41, two outward expansions 42, four positioning grooves 43, and a connecting hole 44.

[0041] The non-metallic sheet 40 is the middle part of the non-metallic material, and both it and the metallic sheet 30 are rectangular in structure. Two notches 45 are formed on the two short sides of the non-metallic sheet 40.

[0042] The connecting hole 44 is a fisheye hole, which forms the non-metallic sheet 40 and is located between the two notches 45. The fastener 25 passes through the connecting hole 44 and is fixed to the metal sheet 30, so that the non-metallic sheet 40 is attached to the inner surface (or bottom surface) of the metal sheet 30. At the same time, the notch 45 does not prevent other fasteners 29 from passing through the fixing hole 35.

[0043] The two side plates 41 are made of non-metallic material and stand side by side of the non-metallic plate 40 to form a single unit, giving the secondary fastener 24 a U-shaped structure design. When the non-metallic plate 40 is attached to the metal plate 30, the side plates 41 are located inside the main fastener 23, achieving the connection where the secondary fastener 24 covers the side rod 22, guiding the front bed plate 12 to slide along the length of the side rod 22. The secondary fastener 24 is made of non-metallic material, which can absorb vibration and reduce noise.

[0044] The outward extension 42 is the end of the side plate 41 that extends outward, separating the metal outward extension 32 from the side rod 22. It can guide the side rod 22 between the two side plates 41, and also has the functions of absorbing vibration and reducing noise.

[0045] The two positioning grooves 43 are formed on both sides of the side piece 41. The positioning grooves 43 do not affect the interlocking action between the fixing pin 60 and the main fixing member 23.

[0046] As shown in Figures 2 and 10, the volume of the rear bed board 13 is approximately the same as that of the front bed board 12, and the same number of fixing components 21 and bed board frame 27 with the same structure can be installed on its back.

[0047] The difference is that, in the pre-assembly process, the rear bed board 13 stands vertically on the bed frame 11 and is adjacent to the rear end (also known as the foot end) of the bed.

[0048] During assembly, the rear bed board 13 lies flat on the bed frame 11. Another force acts on the rear bed board 13 in the opposite direction of arrow 15 (see Figure 7), causing the bed board frame 27 to slide relative to the bed frame 11 to the installation position.

[0049] In the installation position, the positioning slot receives the retaining pin 60, together forming an interlocking structure. Then, the rear bed plate 13 can be quickly assembled on the bed frame 11 using two (or even one) fasteners 29.

[0050] It is worth noting that the assembly order of the rear bed board 13 and the front bed board 12 can be arbitrarily interchanged. Secondly, the rear bed board 13 and the front bed board 12 are spaced apart from each other, so that the two connecting rods 26 are placed side by side on the bed frame 11.

[0051] As shown in Figure 12, the connecting rod 26 of the middle bed board 14 and the rear bed board 13 are interlocked, and the connecting rod 26 of the front bed board 12 is then screwed together with a single fastener 48 to fix the middle bed board 14 to the bed frame 11.

[0052] As shown in Figures 11 and 13, the smallest bed board in terms of volume is the middle bed board 14. The side facing the upper right of Figure 11 is the front, and the other side is defined as the back 61 of the middle bed board 14. The middle bed board 14 is provided with two fasteners 62, a connecting piece 66, and a recess 67.

[0053] In this embodiment, the fastener 62 is a metal sheet that can be continuously bent into: a connecting part 63, a supporting part 64 and a fastening part 65.

[0054] The connecting part 63 is located at one end of the fastener 62 and is fixed to the back side 61 of the intermediate bed board 14 by screws, rivets or other fasteners, so that the fastener 62 is adjacent to one side of the intermediate bed board 14.

[0055] The support portion 64 is the middle section of the fastener 62, used to connect the connecting portion 63 and the buckle portion 65. The support portion 64 is bent relative to the connecting portion 63, and its length is equal to the distance from the connecting portion 63 to the buckle portion 65.

[0056] The buckle 65 is bent relative to the support 64, and its bending direction is opposite to that of the connecting part 63. When the connecting part 63 is fixed to the back surface 61, there is an opening between the buckle 65 and the back surface 61 of the intermediate bed board 14.

[0057] During assembly, the opening structure can receive the connecting rod 26 of the rear bed plate 13, so that the buckle 65 of the latch 62 and the connecting rod 26 form an interlocking structure.

[0058] In addition, the fastener 62 also has a cover (not labeled), made of plastic or other non-metallic materials. This cover covers the entire buckle portion 65 and a portion of the support portion 64, without affecting the fastening function of the fastener 62. In some embodiments, the cover is omitted, which is also within the scope of this invention.

[0059] The connecting piece 66 is located on the opposite side of the intermediate bed board 14 and is thinner than the intermediate bed board 14. The connecting piece 66 forms a hole 68, which corresponds to a positioning hole 28 of the connecting rod 26 of the front bed board 12. A single fastener 48 passes through the hole 68 and the positioning hole 28 to lock the connecting piece 66 to the connecting rod 26, so that the intermediate bed board 14 lies flat on the bed frame 11.

[0060] The recess 67 is recessed into the front of the intermediate bed plate 14, just above the connecting piece 66, to accommodate the head (not labeled) of the fastener 48, so that the front of the intermediate bed plate 14 maintains a flat structure.

[0061] In summary, the present invention, by using a fixing component and a fixing pin (as well as a snap-fit ​​component and a connecting rod) to form an interlocking structure, not only reduces the number of screw-like fasteners used, but also improves assembly efficiency and reduces noise, thus possessing industrial applicability.
