Description

Technical Field

[0001] The utility model relates to the technical field of furniture, and more particularly to an easy-to-assemble bed frame. Background Art

[0002] A bed frame is a common piece of furniture used to hold a mattress. Its primary function is to provide a stable support structure upon which a mattress can be placed, forming a bed for rest and sleep. With the rapid development of logistics and online shopping, many consumers are purchasing furniture, such as bed frames, on their own. Due to their large size, traditional one-piece bed frame designs take up a significant amount of space during transportation and storage. To facilitate transport, bed frames are often assembled. By breaking down the bed frame into multiple components, such as the frame and legs, which can be folded or plugged together for assembly, the space required for packaging can be significantly reduced, lowering shipping costs.

[0003] However, existing assembled bed frames are either disassembled in relatively small pieces, which makes packaging and transportation easier but also makes it difficult for consumers to sort out the pieces and troublesome to install; or they are disassembled in a relatively small number of pieces, which is convenient for installation but not conducive to packaging and transportation. This is especially true for solid wood bed frames, which are usually composed of multiple parts and require tools such as screwdrivers and wrenches to fix. During the assembly process, solid wood bed frames require precise alignment of each component and ensure that all screws are tightened in place. However, due to the thermal expansion and contraction characteristics of solid wood materials, it is difficult to achieve completely accurate dimensional matching, which makes detailed adjustments complicated and prone to errors. In addition, solid wood bed frames are heavy, making them difficult to handle and move, which increases the difficulty of assembly. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the present invention provides an easy-to-assemble bed frame, which can simplify the assembly steps and easily complete the assembly of the bed frame without complicated tools, thereby reducing the difficulty of assembling the bed frame.

Detailed implementation manners

[0027] The following further describes the implementation manners of the present utility model in detail in conjunction with the drawings and embodiments. The following detailed description of the embodiments and the drawings are used to exemplarily illustrate the principle of the present utility model, but cannot be used to limit the scope of the present utility model, that is, the present utility model is not limited to the described embodiments.

[0028] For a better understanding of the present utility model, the following further describes the present utility model in conjunction with the drawings and implementation manners:

[0029] Refer to Figure 1 and Figure 2As shown in the figure, a kind of easily assembled bed frame provided by the utility model includes two cross beams 1 arranged parallel to each other front and back, and two longitudinal beams 2 arranged parallel to each other left and right. The two cross beams 1 and the two longitudinal beams 2 are sequentially connected end to end to form a rectangular frame structure. The cross beam 1 and the longitudinal beam 2 are connected through a first connecting component 3. The first connecting component 3 includes a first connecting piece 31 and a second connecting piece 32. The first connecting piece 31 is installed on the cross beam 1, and the second connecting piece 32 is installed on the longitudinal beam 2. The first connecting piece 31 is provided with a slot 311, and at least a part of the second connecting piece 32 is inserted into the slot 311 so that the cross beam 1 and the longitudinal beam 2 are connected. With such a design, the quick connection between the cross beam 1 and the longitudinal beam 2 is realized. This plug-in design greatly simplifies the assembly steps. Without complex tools, the assembly work of the bed frame can be easily completed, reducing the assembly difficulty of the bed frame. Secondly, due to the plug-in connection, the bed frame can be easily disassembled and reassembled when needed, which is convenient for transportation or storage, thus reducing the transportation cost.

[0030] See Figure 3 and Figure 4 As shown in the figure, the first connecting piece 31 includes a first base part 312, a first extension part 313 and two first bending parts 314. The two first bending parts 314 are formed by bending the front and rear ends of the first base part 312 towards the same side and inclining towards each other. The first base part 312 and the two first bending parts 314 cooperate to define the slot 311. The first extension part 313 is formed by protruding outward along the horizontal direction from the bottom of the first base part 312. The second connecting piece 32 includes a second base part 321, a second extension part 322 and two second bending parts 323. The two second bending parts 323 are formed by bending the front and rear ends of the second base part 321 towards the same side and inclining away from each other. The second extension part 322 is formed by protruding outward along the horizontal direction from the bottom of the second base part 321. When the second connecting piece 32 is inserted into the slot 311 of the first connecting piece 31 from top to bottom, the two second bending parts 323 are in contact with the two first bending parts 314, and the second extension part 322 overlaps on the first extension part 313. With such a design, the connection firmness between the first connecting piece 31 and the second connecting piece 32 is enhanced, so that the deformation or loosening of the bed frame can be prevented.

[0031] When a person turns over in bed, especially a person with a larger body size or a larger movement amplitude, a relatively large lateral force and torsional force will be generated on the bed frame. Traditional connection methods (such as screw fixation) may become loose or produce friction sounds when subjected to the turning force, affecting the sleep quality. In the embodiment of the present utility model, the two first bending portions 314 of the easily assembled bed frame are formed by bending the front and rear ends of the first base portion 312 toward the same side and inclining toward each other. The first base portion 312 and the two first bending portions 314 cooperate to define a slot 311. The two second bending portions 323 are formed by bending the front and rear ends of the second base portion 321 toward the same side and inclining away from each other. When the second connector 32 is inserted into the slot 311 of the first connector 31 from top to bottom, the two second bending portions 323 and the two first bending portions 314 are in contact, and the second extension portion 322 overlaps on the first extension portion 313. With such a design, the first bending portion 314 and the second bending portion 323 are in close contact through the plug-in structure, which can not only effectively resist the thrust generated when a person turns over, prevent the bed frame from deforming or loosening, but also reduce the noise generated due to loosening, ensuring a quiet sleep environment.

[0032] See Figures 2 to 4 As shown, the easily assembled bed frame provided by the embodiment of the present utility model further includes a support foot 4. A first mounting hole 3131 penetrating the thickness of the first extension portion 313 is provided on the first extension portion 313, and a second mounting hole 3221 penetrating the thickness of the second extension portion 322 is provided on the second extension portion 322. At least a part of the mounting post at the upper end of the support foot 4 is inserted into the first mounting hole 3131 and the second mounting hole 3221. With such a design, the support foot 4 can not only be used to support components such as the cross beam 1 and the longitudinal beam 2, but also fix the first connector 31 and the second connector 32, enhancing the connection firmness between the first connector 31 and the second connector 32, thereby preventing the bed frame from becoming loose.

[0033] See Figures 2 to 4 As shown, a fixing piece 324 is provided on one side of the second base portion 321. The fixing piece 324 includes an integrally formed first metal piece 3241, a second metal piece 3242, and a third metal piece 3243. The first metal piece 3241 and the third metal piece 3243 are arranged along the vertical direction, and the first metal piece 3241 and the third metal piece 3243 are parallel to each other. The first metal piece 3241 and the third metal piece 3243 are connected by the second metal piece 3242, and the second metal piece 3242 is arranged horizontally. With such a design, the integrally formed first metal piece 3241, second metal piece 3242, and third metal piece 3243 form a stable support frame, providing stable support for the longitudinal beam 2.

[0034] When a person lies on the bed, the bed frame will be subjected to a vertically downward pressure. With the above design, the fixing piece 324 can effectively disperse and transfer these pressures, avoiding structural damage or deformation caused by excessive stress on a single point.

[0035] See Figure 7 As shown, the longitudinal beam 2 includes a beam main body 21 and a protruding portion 22 integrally formed with the beam main body 21. The protruding portion 22 extends along the length direction of the beam main body 21. The protruding portion 22 is placed on the second metal piece 3242 and is arranged in parallel left and right. A plurality of slats 9 are provided on two longitudinally arranged beams 2. Both ends of the plurality of slats 9 are fixedly installed on two parallel protruding portions 22 through Christmas tree fasteners. In this embodiment, there is a height difference between the upper end surface of the protruding portion 22 and the upper end surface of the beam main body 21. The horizontal height of the upper end surface of the protruding portion 22 is lower than the horizontal height of the upper end surface of the beam main body 21. When the slat 9 is fixed on the protruding portion 22, the horizontal height of the upper end surface of the slat 9 is lower than or equal to the horizontal height of the upper end surface of the beam main body 21, which not only makes the overall structure of the bed frame compact but also optimizes the space utilization rate.

[0036] Secondly, the bed frame often comes into contact with the human body, so it is crucial to avoid sharp or protruding edges. As an important part of the bed frame, if the two ends of the slat 9 are not properly designed and protrude too much, it may cause injuries such as scratches and collisions to the user inadvertently. With the above structural design of the present application, by fixing the slat 9 on the protruding portion 22 lower than the upper end surface of the beam main body 21, the safety risk of the user being injured due to the excessive protrusion of the slat 9 is greatly reduced.

[0037] The installation of the traditional support beam 7 requires precisely aligning the screw holes on the support beam 7 with the screw holes on the cross beam 1, and then screwing in the screws to fixedly connect the two to form an integral part. However, when installing the bed frame, holding one end of the support beam 7, since the center of gravity of the support beam 7 is usually located at or near its geometric center and not at the held end, the gravity of the support beam 7 will generate a moment around the holding point. This moment tends to make the support beam 7 rotate around the holding point until its center of gravity reaches the lowest point (i.e., the support beam 7 tilts and one end touches the ground). To resist this moment and keep the support beam 7 horizontal, a moment equal in magnitude and opposite in direction to the gravity moment needs to be applied. However, due to the fixed position and limited area of the hand support point, it is very difficult to apply such a moment, especially without additional support or auxiliary tools, it is difficult to ensure that the support beam 7 remains horizontal, thus making it difficult to align the screw holes of the support beam 7 with the screw holes on the cross beam 1. When the screw holes of the support beam do not align with the screw holes on the cross beam 1, it will cause the screws to be difficult to screw in or the screw-in depth to be insufficient, resulting in the problem of poor stability of the bed frame.

[0038] Based on this, the easy - assembled bed frame provided by the embodiment of the present utility model further includes a support beam 7. Refer to Figures 5 to 7 As shown, the support beam 7 is arranged along the length direction of the longitudinal beam 2 and is connected to the two cross beams 1 through a second connection assembly 8. The second connection assembly 8 includes a first clamping member 81 arranged at both ends of the support beam 7 and a second clamping member 82 arranged on the cross beam 1. The first clamping member 81 can be inserted into the second clamping member 82 from top to bottom. With such a design, not only can the firmness of the bed frame be enhanced, but also the assembly difficulty is reduced, enabling users to quickly assemble the support beam 7 to the cross beam 1. Preferably, a card slot 821 is provided in the second clamping member 82, and the slot width of the card slot 821 gradually decreases from top to bottom in the vertical direction. When the support beam 7 and the cross beam 1 are in the assembled state, the first clamping member 81 is embedded in the card slot 821 of the second clamping member 82, and the two side walls of the first clamping member 81 are in contact with the two side walls of the second clamping member 82. With such a design, the complex step of aligning the screw holes is eliminated, and the connection and fixation between the support beam 7 and the longitudinal beam 2 can be achieved only through the plug - in form, thus reducing the assembly difficulty.

[0039] In this embodiment, both the cross beam 1 and the longitudinal beam 2 are extrusion - molded parts. With such a design, the overall weight of the bed frame can be reduced, thereby reducing the transportation cost.

[0040] Refer to Figures 8 to 9 As shown, first end caps 5 are provided at both ends of the cross beam 1, and at least a part of the first end caps 5 is inserted into the cross beam 1. Second end caps 6 are provided at both ends of the longitudinal beam 2, and at least a part of the second end caps 6 is inserted into the longitudinal beam 2. Specifically, the first end cap 5 is provided with a plurality of first connection holes 51, and the second end cap 6 is provided with a plurality of second connection holes 61. The plurality of first connection holes 51 correspond one - to - one with the plurality of first through - holes 3121 on the first base 312 for fasteners to pass through, and the plurality of second connection holes 61 correspond one - to - one with the plurality of second through - holes 3244 on the fixing piece 324 for fasteners to pass through.

[0041] For further explanation, the embodiment of the present utility model also provides an assembly method for the easy - assembled bed frame, which is as follows:

[0042] Step 1: Insert the two first end caps 5 into the front and rear end parts of the cross beam 1 respectively, fixedly install the first connecting member 31 on both ends of the cross beam 1 with screws, and fixedly install the second clamping member 82 in the middle of the cross beam 1 with screws, thereby obtaining the bed tail plate assembly;

[0043] Step 2: Insert the two second end caps 6 into the front and rear end parts of the longitudinal beam 2 respectively, fixedly install the second connecting member 32 on both ends of the longitudinal beam 2 with screws, thereby obtaining the side plate assembly;

[0044] Step 3: Insert the side plate assembly into the two parallel headboard assemblies from top to bottom. Repeat this operation to insert the other side plate assembly into the two parallel headboard assemblies from top to bottom. Then insert the support beam 7 into the two parallel headboard assemblies from top to bottom to assemble the bed frame main body.

[0045] Step 4: Lift the bed frame main body in Step 3, screw the corresponding support feet 4 into the middle of the four corners of the bed frame main body and the support beam 7, then place it horizontally, and finally place the slat 9. The slat 9 is fixed to the corresponding holes on the longitudinal beam 2 through Christmas tree fasteners to complete the assembly.

[0046] It is worth mentioning that the above Step 1 and Step 2 can be completed at the factory end, and the above Step 3 and Step 4 are completed at the user end, thus reducing the assembly difficulty at the user end.
