FIELD OF THE DISCLOSURE

The present disclosure relates to the field of furniture, and in particular to a bed frame.

BACKGROUND OF THE DISCLOSURE

Beds are a common piece of furniture used for resting at home. The beds generally comprise a bed frame and a mattress. The mattress is laid on a support surface of the bed frame. In recent years, the development of assembled bed frames is getting faster and faster. Since the assembled bed frames can be disassembled into several parts for independent packaging and transportation, it can reduce a space occupied by the bed frame and facilitate transportation of the bed frame.

Each component of the existing assembled bed frame generally requires multiple screws to assemble, which is relatively cumbersome during assembly, and the assembly of the screws requires tools. At the same time, there are cases where screws are used incorrectly during assembly and need to be disassembled and re-screwed, resulting in inconvenient assembly. Moreover, the screws are easily lost, making installation difficult, time-consuming, and labor-intensive.

Therefore, there is a need to improve the assembly structure of the assembled bed frame so that the bed frame can be assembled without screws and is safe, strong, and reliable.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present disclosure will be further described below in combination with the accompanying drawings and embodiments.

Referring to FIGS. 1 to 12, this embodiment provides an assembled bed frame structure, which comprises a bed frame having a supporting rod 1, a lateral rod 2, a beam rod 3 for an inner supporting member, and a longitudinal rod 4 defining a bed support surface. The assembly connection between each component is as follows. The supporting rod 1 and the beam rod 3 are fixedly connected to each other by an inserting connection or a buckling connection, the beam rod 3 and the longitudinal rod 4 are fixedly connected to each other by an inserting connection or a buckling connection, and the lateral rod 2 and the longitudinal rod 4 are fixedly connected to each other by an inserting connection or a buckling connection. The supporting rod 1 defines a foldable structure at a middle hinge 11. The middle hinge 11 is disposed with a support leg 5. Each end of the supporting rod 1 is disposed with a bed leg 6 for support. Each end of the supporting rod 1 is disposed with a fixed seat 12, and the bed leg 6 is rotatably connected to the fixed seat 12. The fixed seat 12 comprises an insertion opening 121, which is configured for a connection with the lateral rod 2. The fixed seat 12 is disposed with a locking member, and the bed leg 6 is disposed with a first locking component and a second locking component.

When the bed leg 6 is rotated to a support state, the first locking component and the locking member are locked to each other so that the bed leg 6 is locked in the support state. In the support state, the second locking component enables an insertion end 24 of the lateral rod 2 to be locked in the insertion opening 121. The assembled bed frame assembled by this assembly connection method does not require screws for fixation, which is safe, strong, and reliable.

Steps to assemble the assembled bed frame are described below.

Step 1: an assembly of two of the supporting rods 1 on two sides of the bed frame is completed. In this embodiment, the supporting rod 1 is divided into a left supporting rod 1a and a right supporting rod 1b at the middle hinge 11. The left supporting rod 1a and the right supporting rod 1b are respectively pivotally connected to a left side and a right side of a connecting piece 51, and a support leg 5 is fixedly disposed at a middle position of the connecting piece 51. When one of the left supporting rod 1a or the right supporting rod 1b is unfolded relative to the other of the left supporting rod 1a or the right supporting rod 1b, the connecting piece 51 is relatively rotated and simultaneously achieves unfolding of the support legs 5 to define a middle support function.

Step 2: When the supporting rod 1 is in an unfolded state, an assembly of the bed leg 6 and the lateral rod 2 can be completed to define the bed frame. In this embodiment, the bed leg 6 is rotatably connected to an end portion of the supporting rod 1 through a rotating seat 7. Two of the bed legs 6 are respectively rotatably connected to two ends of the supporting rod 1. The rotating seat 7 is pivotally connected to the fixed seat 12 on the supporting rod 1 through a rivet 71. The first locking component is disposed on a side of the rotating seat 7 connected to the fixed seat 12, and the second locking component is disposed on a side of the rotating seat 7 connected to the bed leg 6. During assembly, the insertion end 24 of the lateral rod 2 is first inserted into the insertion opening 121 of the fixed seat 12. After insertion of the lateral rod 2 is completed, the bed leg 6 is rotated to be unfolded. When the bed leg 6 is rotated to be fully unfolded to define the support state relative to the supporting rod 1, the locking member and the first locking component are locked together so that the bed leg 6 no longer rotates. At the same time, when the bed leg 6 is in the support state, the insertion end 24 of the lateral rod 2 is locked in the insertion opening 121 through the second locking component to inhibit movement of the lateral rod 2 in a direction away from the insertion opening 121.

Step 3: an assembly of the beam rod 3 is completed on the bed frame. A connection structure between the supporting rod 1 and the beam rod 3 comprises a slot 13 located on a rod body of the supporting rod 1 and a buckle sheet 31 located on an end portion of the beam rod 3. The slot 13 and the buckle sheet 31 define a snap connection.

Step 4: After an assembly of the beam rod 3 on the bed frame is completed, an assembly of the longitudinal rod 4 is completed. A connection structure between the beam rod 3 and the longitudinal rod 4 or the lateral rod 2 and the longitudinal rod 4 comprises a buckle opening 23 with an elastic clamping member 231 located on a rod body of the beam rod 3 or the lateral rod 2 and a buckle portion 41 having a clamping hole 411 located on an end portion of the longitudinal rod 4. The buckle portion 41 is inserted into the buckle opening 23 along an insertion direction to define a snap connection with the elastic clamping member 231.

Described as above, the overall assembly of the bed frame is completed.

In step 2, a locking and matching structure of the supporting rod 1 and the bed leg 6 is described as follows. The locking member comprises a locking core 122 disposed in the fixed seat 12 and an unlocking member. The first locking component is a locking hole 72 located on the rotating seat 7. The locking core 122 has a certain amount of deformation, and the certain amount of deformation enables the locking core 122 to be locked to or unlocked from the locking hole 72. The unlocking member is a button 123. The button 123 is disposed on an outside of the fixed seat 12, and the outside of the fixed seat 12 is opposite to the locking core 122.

Specifically, an inside of the fixed seat 12 comprises a gap 124. The side of the rotating seat 7 connected to the fixed seat 12 is disposed in the gap 124 and has a certain amount of rotation in the gap 124. The outside of the fixed seat 12 corresponding to the locking core 122 comprises a position-providing hole 1221 in communication with the gap 124. The position-providing hole 1221 is used to provide a space for being pressed by the button 123. In the support state, the locking core 122, the locking hole 72 and the position-providing hole 1221 are coaxially arranged. The locking core 122 penetrates through the locking hole 72 and the position-providing hole 1221 to abut the button 123.

In this embodiment, the locking core 122 comprises an elastic member 1222 and a spherical head 1223, and the spherical head 1223 can reciprocate due to the elastic member 1222. When the rotating seat 7 is rotated with the bed leg 6 until the bed leg 6 is in the support state, the locking hole 72 on the rotating seat 7 corresponds to the locking core 122, and the locking hole 72 provides a space for the locking core 122 to pop out to enable the spherical head 1223 to pop out due to the elastic member 1222 so that the spherical head 1223 is locked to the locking hole 72 to define a locking connection, thereby preventing the bed leg 6 from rotating backward.

Through the gap 124, a rotational connection between the rotating seat 7 and the fixed seat 12 is hidden in the fixed seat 12, thereby achieving overall aesthetics and protecting the rotating seat 7. In order to realize an unlocking function of the button 123, the position-providing hole 1221 is provided on the fixed seat 12. When the locking hole 72 corresponds to the locking core 122, the locking core 122 pops out of the position-providing hole 1221 to abut the button 123. In order to better achieve retraction of the locking core 122 when the locking core 122 is pressed by the button 123 to unlock, the button 123 comprises a pressing protrusion 125 corresponding to the position-providing hole 1221. When the button 123 is pressed, the pressing protrusion 125 is further pressed on the locking core 122 to ensure that the locking core 122 is retracted to be separated from the locking hole 72. When folding the bed leg 6, the button 123 is first pressed, the spherical head 1223 is pressed in to be unlocked from the locking hole 72, and then the bed leg 6 can be rotated for folding.

In step 2, a locking and matching structure of the supporting rod 1 and the lateral rod 2 is described as follows. The insertion end 24 of the lateral rod 2 is disposed with two position-limiting members 22. The two position-limiting members 22 respectively abut two end surfaces of the fixed seat 12 to inhibit movement of the lateral rod 2 frontward and rearward. The second locking component is disposed on an end surface of the rotating seat 7, and when the rotating seat 7 is rotated to the support state, the end surface of the rotating seat 7 is connected to the fixed seat 12 to be configured to abut the supporting rod 1. The second locking component is one or more protrusions 73 having a certain inclination angle. The insertion end 24 of the lateral rod 2 comprises one or more grooves 21. The one or more grooves 21 are located on a lower side of the insertion end 24, and the one or more grooves 21 are matched with a position of the one or more protrusions 73 when the rotating seat 7 is in the support state.

When assembling the lateral rod 2, the insertion end 24 of the lateral rod 2 is first inserted into the insertion opening 121 of the fixed seat 12. A first of the two position-limiting members 22 adjacent to an end surface of the lateral rod 2 is pressed on an end surface of a first side of the fixed seat 12, and a second of the two position-limiting members 22 relatively abuts an end face of a second side of the fixed seat 12 to define a position-limiting connection, so as to inhibit frontward and rearward movement of the lateral rod 2 relative to the supporting rod 1 through the two position-limiting members 22. The two position-limiting members 22 have the following two functions. The two position-limiting members 22 are used to inhibit lateral movement of the lateral rod 2, and the two position-limiting members 22 are used for positioning the one or more grooves 21 so that the one or more grooves 21 on the lower side of the lateral rod 2 can be aligned with the one or more protrusions 73. When the insertion end 24 of the lateral rod 2 is inserted into the insertion opening, the bed leg 6 can be rotated for assembly, and the bed leg 6 is rotated to enable the rotating seat 7 to rotate so that the one or more protrusions 73 on the rotating seat 7 abut the lateral rod 2. The lateral rod 2 is first pushed upward so that the two position-limiting members 22 and an upper side of the lateral rod 2 tightly abut the fixed seat 12, and then the one or more protrusions 73 are inserted into the one or more grooves 21 to further inhibit the lateral rod 2 from moving frontward, rearward, upward, and downward. When the bed leg 6 is locked, the lateral rod 2 is locked and fixed at the same time.

Furthermore, the two position-limiting members 22 are made of plastic, which can play a buffering role. When the bed frame shakes, the two position-limiting members 22 can buffer a collision at a connection between the lateral rod 2 and the supporting rod 1 to avoid making noise due to the collision. The one or more grooves 21 are two square grooves 21, and the one or more protrusions 73 are two protrusions 73, which can play a better position-limiting and fixing role. The two protrusions 73 have a certain inclination angle. When the rotating seat 7 is rotated to enable the two protrusions 73 to be inserted into the two square grooves 21, the certain inclination angle can match a transition position of the two grooves 21. At the same time, the position of the lateral rod 2 can be finely adjusted so that the two protrusions 73 can be better inserted into the two square grooves 21.

In step 3, the connection structure of the beam rod 3 comprises the slot 13 and the buckle sheet 31. The slot 13 is welded to the supporting rod 1, and the buckle sheet 31 is welded to the beam rod 3. A buckle width of the slot 13 is in a trapezoidal shape along an insertion direction to define a slope 131, and a width of the trapezoidal shape gradually decreases along the insertion direction. When the beam rod 3 is pressed downward, the buckle sheet 31 is gradually tightly clamped with the slot 13 along the insertion direction. The slope 131 is inclined at a certain angle, and the buckle sheet 31 has certain elasticity, so that when the beam rod 3 is pressed down, the slot 13 will not be too tight to inhibit the beam rod 3 from being pressed down.

The assembly method of the assembled bed frame structure proposed in this embodiment does not involve a screw locking structure in an entire assembly process. No screw tools are required during assembly. The assembly is simple and fast, and there is no error in assembling parts. It can be achieved without the need for screws to achieve quick assembly and disassembly, while ensuring the safety, firmness, and reliability of the assembled bed frame structure.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto.
