Technical Field

[0001] This utility model belongs to the field of bed frame technology, specifically relating to bed frame connectors, bed frame connecting components, and bed frames. Background Technology

[0002] In one type of bed frame, the foot and side panels are joined at an angle and fastened together. When the joint length is large (e.g., the width of the foot and side panels is ≥10cm when spliced ​​at 45°), the connection between the foot and side panels is not tight enough, that is, there are gaps or unevenness between the foot and side panels. Summary of the Invention

[0003] This invention addresses the shortcomings of existing bed frames with angled joints between the foot and side panels, providing a bed frame connector for this purpose. This connector ensures a tight, seamless, and flush connection between the foot and side panels. The invention also provides a bed frame connecting assembly and a bed frame using this connector. Furthermore, this bed frame connector can also be used to connect the headboard and side panels (when there is no headboard or the headboard is installed later).

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a bed frame connector, wherein the bed frame connector comprises:

[0005] The upper fitting part has two mounting holes;

[0006] The two sides of the mating part are located below the upper mating part and have side mounting holes respectively;

[0007] Both mounting holes have rectangular segments, and the distance between the two mounting holes gradually increases from the side closer to ...

[0008] This utility model discloses a bed frame connector, comprising an upper fitting part and two side fitting parts. The upper fitting part has two upper mounting holes, and the two side fitting parts each have side mounting holes. The distance between the two upper mounting holes gradually increases from the side fitting parts towards the side fitting parts. During bed frame assembly, the side fitting parts are typically first brought close to the side of the bed frame's foot or side. Then, fasteners such as screws are used to pre-tighten the upper fitting parts to the upper surface of the bed frame's foot or side. The side fitting parts are then locked to the bed frame using fasteners such as screws. Simultaneously, the position of the screws in the upper mounting holes changes, guiding the bed side and foot towards each other, ensuring the bed frame's foot and side are tightly fitted. Finally, the fasteners connecting the upper fitting parts to the bed frame's foot or side are tightened. Both upper mounting holes are elongated, thus having rectangular sections. These holes can be oval holes with semicircular ends and a rectangular middle section, or they can be rectangular holes.

[0009] As an improvement, the two upper mounting holes are symmetrical left and right, and the two side mounting holes are symmetrical left and right.

[0010] As an improvement, the side bonding portion is perpendicular to the upper bonding portion.

[0011] As an improvement, both upper mounting holes are oblong holes; the side mounting holes are also oblong holes. An oblong hole, also known as a long hole, has semicircles at both ends and a rectangle in the middle with a width equal to the diameter of the semicircles. Machining oblong holes is relatively easy.

[0012] The improved bed frame connector is an integral piece; the bed frame connector is a hardware component.

[0013] The offset angle of the mounting hole is 10° to 20° as an improvement.

[0014] The bed frame connection assembly includes a bed frame connector, pre-embedded nuts and screws, wherein the bed frame connector is the aforementioned bed frame connector.

[0015] Bed frame, including:

[0016] foot of the bed;

[0017] Both sides of the bed;

[0018] At least two bed frame connecting assemblies, the bed frame connecting assemblies being the aforementioned bed frame connecting assemblies, with pre-embedded nuts located on the inner and upper surfaces of the foot and side of the bed, and screws being divided into side screws and top screws, the side screws passing through the side mounting holes and then being screwed into the pre-embedded nuts on the side, and the top screws passing through the top mounting holes and then being screwed into the pre-embedded nuts on the upper surface.

[0019] As an improvement to the bed frame, the foot and sides of the bed are fitted together at a 45° angle; the width of both the sides and foot is greater than the length of the upper fitted part; and the height of both the sides and foot is greater than the height of the side fitted part.

[0020] As an improvement to the bed frame, the width of both the sides and the foot of the bed is ≥10cm; the length of the upper fitting part is 200mm to 300mm.

[0021] The beneficial effects of the bed frame connector of this utility model are as follows: two upper mounting holes are opened on the upper fitting part, and side mounting holes are opened on the two side fitting parts respectively. The distance between the two upper mounting holes gradually increases along the direction from approaching to moving away from the side fitting part. When assembling the bed frame, the side fitting part is usually first brought close to the side of the bed frame foot or side. Then, the upper fitting part is pre-tightened to the upper surface of the bed frame foot or side by fasteners such as screws. The side fitting part is then locked to the bed frame by fasteners such as screws. At the same time as the side fitting part is locked to the bed frame, the position of the screw in the upper mounting hole changes. The upper mounting hole guides the bed side and bed foot to gradually approach each other, eliminating or reducing the gap between the bed side and bed foot, so that the bed foot and bed side of the bed frame are tightly attached. Finally, the fasteners connecting the upper fitting part to the bed foot or bed side of the bed frame are tightened.

[0022] The bed frame connecting assembly and bed frame of this utility model, using the bed frame connector of this utility model, have all the beneficial effects of the bed frame connector of this utility model. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be explained and described below. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0040] See Figures 1 to 10 The bed frame connector of this utility model embodiment includes:

[0041] The upper fitting part has two mounting holes;

[0042] The two sides of the mating part are located below the upper mating part and have side mounting holes respectively;

[0043] Both mounting holes have rectangular segments, and the distance between the two mounting holes gradually increases from the side closer to ...

[0044] The bed frame connector of this utility model has two upper mounting holes on the upper fitting part and side mounting holes on the two side fitting parts. The distance between the two upper mounting holes gradually increases from the side fitting part to the side fitting part. When assembling the bed frame, the side fitting part is usually first brought close to the side of the bed frame foot or side. Then, the upper fitting part is pre-tightened to the upper surface of the bed frame foot or side using fasteners such as screws. The side fitting part is then locked to the bed frame again using fasteners such as screws. At the same time as the side fitting part is locked to the bed frame, the position of the screw in the upper mounting hole changes. The upper mounting hole guides the bed side and foot gradually closer, eliminating or reducing the gap between the bed side and foot, so that the bed frame foot and side are tightly fitted. Finally, the fasteners connecting the upper fitting part to the bed frame foot or side are tightened.

[0045] Example 1

[0046] See Figures 1 to 7 The bed frame of Embodiment 1 of this utility model includes:

[0047] 5 at the foot of the bed;

[0048] 4 on each side of the bed;

[0049] At least two bed frame connecting assemblies, each bed frame connecting assembly includes a bed frame connector 1, a pre-embedded nut 2 and a screw 3. The bed frame connector 1 includes an upper fitting part 11 with two upper mounting holes 111 and two side fitting parts 12 located below the upper fitting part 11. The two side fitting parts 12 are respectively provided with side mounting holes 121. The two upper mounting holes 111 are symmetrical from left to right, and the two side mounting holes 121 are symmetrical from left to right. The angle between the two side fitting parts 12 is 90°.

[0050] The pre-embedded nut 2 is located on the inner and upper surfaces of the bed end 5 and bed side 4. The screw 3 is divided into a side screw 3 and an upper screw 3. The side screw 3 passes through the side mounting hole 121 and is screwed into the pre-embedded nut 2 on the side. The upper screw 3 passes through the upper mounting hole 111 and is screwed into the pre-embedded nut 2 on the upper surface.

[0051] In this embodiment, each bed frame connection assembly includes a bed frame connector 1, four pre-embedded nuts 2, and four screws 3.

[0052] In this embodiment, the pre-embedded nut 2 is pre-embedded before the bed tail 5 or bed side 4 is formed and becomes integral with the bed tail 5 or bed side 4 after forming. The pre-embedded nut 2 has internal and external threads. The internal thread is used for threaded connection with the screw 3, and the external thread is used to improve the connection strength between the pre-embedded nut 2 and the bed side 4.

[0053] In this embodiment, the side fitting portion 12 is perpendicular to the upper fitting portion 11.

[0054] In this embodiment, the upper mounting hole 111 is an oblong hole, thus accommodating machining and assembly errors of the bed side 4 or bed tail 5. The two ends of the oblong hole are semicircles, and the middle is a rectangle (rectangular segment) with a width equal to the diameter of the semicircles. The oblong hole is relatively easy to machine.

[0055] In this embodiment, the side mounting hole 121 is an oval hole, which can accommodate the machining and assembly errors of the bed side 4 or the bed tail 5.

[0056] In this embodiment, the bed frame connector 1 is a single piece.

[0057] In this embodiment, the bed frame connector 1 is a hardware component.

[0058] In this embodiment, the distance between the two upper mounting holes gradually increases along the direction from the closer side to the farther side of the mating portion. The offset angle of the upper mounting hole 111 is 10° to 20°. Figure 6 As shown, the offset angle of the upper mounting hole 111 is 15°. The offset angle of the upper mounting hole 111 is its angle relative to the center line of the connector.

[0059] In this embodiment, the foot of the bed 5 and the side of the bed 4 are fitted together at a 45° angle. In other embodiments, the foot of the bed 5 and the side of the bed 4 may be fitted together at other angles such as 30° or 60°.

[0060] In this embodiment, the width of the foot of the bed 5 and the side of the bed 4 is ≥10cm.

[0061] In this embodiment, the widths of both the bed side 4 and the bed foot 5 are greater than the length of the upper fitting portion 11.

[0062] In this embodiment, the heights of the bed side 4 and the bed foot 5 are both greater than the height of the side fitting part 12.

[0063] In this embodiment, the width of both the bed side 4 and the bed foot 5 is ≥10cm; the length of the upper fitting part 11 is 200mm to 300mm.

[0064] In this embodiment, the headboard 6 has a headboard. In other embodiments, when the headboard 6 does not have a headboard, the bed side 4 can be connected to the headboard 6 using a connecting component.

[0065] See Figure 7 The principle of the connecting component in this embodiment that makes the bed side and the bed foot fit together is as follows: During assembly, the bed side 4 and the bed foot 5 are first roughly attached together. The bed frame connector 1 is placed at the connection between the bed side 4 and the bed foot 5. Then, the upper screw 3 is screwed into the upper mounting hole 111. At this time, the upper screw 3 is not tightened. Then, the side screw 3 is screwed into the side mounting hole 121 and tightened. Finally, the upper screw 3 is tightened. When tightening the side screw 3, the gap between the side fitting part 12 and the bed side 4 or the bed foot 5 gradually decreases. During the process of the side fitting part 12 fitting with the bed side 4 or the bed foot 5, the bed side 4 or the bed foot 5 gradually moves closer under the guidance of the upper mounting hole 111 of the bed frame connector 1, thereby eliminating or reducing the gap between the bed side 4 and the bed foot 5.

[0066] The beneficial effects of the bed frame in Embodiment 1 of this utility model are as follows: When assembling the bed frame, the upper screw is first pre-tightened (not fully tightened) to the foot 5 or side 4 of the bed. Then, the side fitting part 12 is tightly attached to the side of the foot 5 or side 4 of the bed frame using the side screw 3. Finally, the upper fitting part 11 is tightly attached to the upper surface of the foot 5 or side 4 of the bed frame using the upper screw 3. When tightening the side screw 3, the side 4 or foot 5 of the bed gradually moves closer under the guidance of the upper mounting hole 111 of the bed frame connector 1, thereby ensuring that the foot 5 and side 4 are tightly fitted without gaps; there is also no height difference between the foot 5 and side 4.
