Description

Technical Field

[0001] This utility model relates to a folding bed frame. Background Technology

[0002] With increasingly sophisticated family childcare needs, co-sleeping with parents is becoming common. However, the width of existing adult beds is limited. To prevent children from being squeezed by adults during sleep, modular beds specifically designed for children have emerged on the market. These modular beds typically connect to the side of an adult bed, effectively expanding the sleeping space and improving the safety and comfort of children's sleep.

[0003] Most modular beds on the market currently use a fixed structure. While this can meet basic usage needs, their rigid, non-foldable design results in a large space occupation and makes storage and transportation extremely inconvenient when children grow to the stage where they can sleep independently or when they are no longer needed for daily use.

[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a folding bed frame that is simple in structure, easy to fold, and occupies little space when folded.

[0006] This utility model is achieved through the following technical solution:

[0007] A folding bed frame includes a vertical left support frame and a vertical right support frame. A side rail connects the left and right support frames. The left support frame is rotatably connected to a left rail that can be unfolded or folded relative to the side rail, about a first vertical axis. The right support frame is rotatably connected to a right rail that can be unfolded or folded relative to the side rail, about a second vertical axis. A bed frame is also provided between the left and right support frames, rotatably connected to both about a third horizontal axis, and can be unfolded or folded relative to the side rail when rotated. The left rail has a left positioning part for supporting and positioning the bed frame when the side rail is unfolded, and the right rail has a right positioning part for supporting and positioning the bed frame when the side rail is unfolded.

[0008] The left support frame includes a left leg supported on the ground. A left vertical rod is fixed to the upper end of the left leg.

The open end of the left guardrail frame is rotatably connected to the left upper rod and the left middle rod around the first axis, allowing it to rotate relative to the side guardrail frame and the left support frame. A left locking device is provided between the left guardrail frame and the left support frame to lock them together.

[0009] The right support frame includes a right leg supported on the ground. A right vertical rod is fixed to the upper end of the right leg. A right upper rod, a right middle rod, and a right lower rod are fixedly connected from top to bottom on one side of the right vertical rod, which are spaced apart from each other and protrude to one side of the right vertical rod. The right guardrail frame includes a right support frame. The right support frame includes a right support rod at one end, which is rotatably connected to the right lower rod around the second axis. The other end of the right support rod is fixedly connected to a right support leg that can be supported on the ground. The right guardrail frame also includes a U-shaped right guardrail frame. The open end of the right guardrail frame is rotatably connected to the right upper rod and the right middle rod around the second axis, allowing it to rotate relative to the side guardrail frame and the right support frame. A right locking device is provided between the right guardrail frame and the right support frame to lock the two together.

[0010] The right locking device includes a side opening on the side of the right support frame, a locking block at the lower end of the right guardrail frame that can engage with the side opening when it rotates, a locking groove vertically connected to the side opening on the right support frame, a locking pin on the right guardrail frame that can move up and down relative to it and can be inserted downward into the locking groove when the locking block engages with the side opening, an exposed push button on the right guardrail frame that can push the locking pin upward, and a return spring inside the right guardrail frame that can push the locking pin downward to reset.

[0011] The longitudinal section of the card block is inverted T-shaped, and the side opening is adapted to the shape of the card block.

[0012] The left positioning part includes a left positioning block located at the junction of the left support leg and the left support rod. The left positioning block has a left positioning groove that allows the bed frame to be inserted when the bed frame is unfolded. The right positioning part includes a right positioning block located at the junction of the right support leg and the right support rod. The right positioning block has a right positioning groove that allows the bed frame to be inserted when the bed frame is unfolded.

[0013] The left and right positioning parts are integral structures formed by bending metal sheets. The bottom surfaces of both sides of the bed frame are provided with rubber pads, which abut against the bottom of the left and right positioning grooves when the bed frame is unfolded.

[0014] One end of the bed frame is rotatably connected to the middle of the lower left rod, and the other end is rotatably connected to the middle of the lower right rod.

[0015] The bed frame includes a front crossbar and a rear crossbar. Multiple spaced grid bars are provided between the front and rear crossbars. Connecting posts are provided on the two outermost grid bars.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 7 As shown, this utility model provides a folding bed frame, mainly including a left support frame 1, a right support frame 2, a side guardrail frame 3 connecting the two, a left guardrail frame 4 rotatably mounted on the left support frame 1, a right guardrail frame 5 rotatably mounted on the right support frame 2, and a bed frame 6 rotatably mounted between the left and right support frames 1 and 2. A folding bed is formed by covering the left guardrail frame 4, right guardrail frame 5, and side guardrail frame 3 with fabric covers and placing a mattress on the bed frame 6. Furthermore, this folding bed frame can switch between an unfolded state and a folded state. In the unfolded state, the folding bed can be placed to the side of an adult bed, expanding the width of the adult bed, allowing children to sleep inside, preventing them from being squeezed when sleeping with their parents, ensuring safety. When the folding bed is not in use, the mattress is removed from the bed frame 6, and the bed frame 6, left guardrail frame 4, and right guardrail frame 5 can be rotated to fold it. After folding, it occupies little space and is easy to move.

[0030] Specifically, such as Figures 1 to 7 As shown, the left support frame 1 includes a left leg 11 supported on the ground, with a left vertical rod 12 fixed to its upper end. A left upper rod 13, a left middle rod 14, and a left lower rod 15, spaced apart and protruding towards the left vertical rod 12, are fixedly connected from top to bottom to one side of the left vertical rod 12. Similarly, the right support frame 2 includes a right leg 21, with a right vertical rod 22 fixed to its upper end. A right upper rod 23, a right middle rod 24, and a right lower rod 25, spaced apart and protruding towards the right vertical rod 22, are fixedly connected from top to bottom to one side of the right vertical rod 22. The side guardrail frame 3 connects the left support frame 1 and the right support frame 2, and includes two vertical rods 31. The lower ends of the two vertical rods 31 are connected by a lower connecting rod 32, and their upper ends are connected by an upper connecting rod 33. The left vertical rod 12 is fixedly connected to the adjacent vertical rod 31, and the right vertical rod 22 is fixedly connected to the adjacent vertical rod 31, thus forming a stable frame structure.

[0031] like Figure 1 , Figure 2 and Figure 7 As shown, the left guardrail frame 4 is connected to the left support frame 1 by rotating around a vertical first axis A, allowing it to unfold or fold inward relative to the side guardrail frame 3. The left guardrail frame 4 mainly includes a left support frame 41 and a left guardrail frame 42. The left support frame 41 consists of a left support rod 411 and a left support leg 412. One end of the left support rod 411 is rotatably connected to the lower left rod 15 around the first axis A, and the other end is fixedly connected to the left support leg 412, which can be supported on the ground. The left guardrail frame 42 is U-shaped, and its open end is rotatably connected to the upper left rod 13 and the middle left rod 14 around the first axis A, respectively, so that the left guardrail frame 42 can rotate together with the side guardrail frame 3 and the left support frame 41. A left locking device 43 is provided between the left guardrail frame 42 and the left support frame 41 to lock them together. The structure of the right guardrail frame 5 is symmetrical to that of the left guardrail frame 4. The right guardrail frame 5 is rotatably connected to the right support frame 2 via a second vertical axis B. It includes a right support frame 51 and a right guardrail frame 52. The right support frame 51 consists of a right support rod 511 and a right support leg 512. One end of the right support rod 511 is rotatably connected to the lower right rod 25 around the second axis B, and the other end is fixedly connected to the right support leg 512, which can be supported on the ground. The right guardrail frame 52 is U-shaped, and its open end is rotatably connected to the upper right rod 23 and the middle right rod 24 around the second axis B, so that the right guardrail frame 52 can rotate together with the side guardrail frame 3 and the right support frame 51. A right locking device 53 is provided between the right guardrail frame 52 and the right support frame 51 to lock them together. When the folding bed is attached to the adult bed, the left guardrail frame 42 and the left support frame 41 are locked together, as are the right guardrail frame 52 and the right support frame 51, to protect the child and prevent falls. For easy loading or unloading of the child, the left guardrail frame 42 can be opened by unlocking the left locking device 43, or the right guardrail frame 52 can be opened by unlocking the right locking device 53, thus facilitating use.

[0032] like Figure 4 and Figure 5As shown, in a preferred embodiment, the specific structure of the right locking device 53 is as follows: It includes a side opening 531 on the side of the right support frame 51, and a locking block 532 fixed at the lower end of the right guardrail frame 52. When the right guardrail frame 52 rotates, the locking block 532 can be engaged into the side opening 531. The right support frame 51 is also vertically provided with a locking groove 533 communicating with the side opening 531. A locking pin 534 that can move up and down relative to the right guardrail frame 52 is installed. After the locking block 532 is engaged into the side opening 531, pressing down on the locking pin 534 will insert it into the locking groove 533, thereby achieving a secure lock. The right guardrail frame 52 is provided with an exposed push button 535, which is used to push the locking pin 534 upward to disengage from the locking groove 533, at which point the right guardrail frame 52 can be rotated and opened. The right guardrail frame 52 is also equipped with a return spring 536, which can push the locking pin 534 to automatically return downward after unlocking. When the right guardrail frame 52 is locked to the right support 51, the return spring 536 applies a downward pushing force to the locking pin 534 to maintain the locked state. To further enhance stability, the longitudinal section of the locking block 532 is preferably inverted T-shaped, and the shape of the side opening 531 is adapted to it. In this embodiment, the left locking device 43 can adopt the same or similar structure as the right locking device 53, which will not be described in detail here.

[0033] like Figure 1 , Figure 2 and Figure 7 As shown, the bed frame 6 is connected between the left support frame 1 and the right support frame 2 by rotating around a third transverse axis C. Specifically, one end of the bed frame 6 is rotatably connected to the middle of the lower left rod 15, and the other end is rotatably connected to the middle of the lower right rod 25. The bed frame 6 can be flipped up and folded or unfolded down to a horizontal state. The bed frame 6 specifically includes a front crossbar 61, a rear crossbar 62, and multiple spaced grid bars 63 connecting the two. Connecting posts 64 are provided on the two outermost grid bars 63, and the bed frame 6 is rotatably connected to the lower left rod 15 and the lower right rod 25 through these two connecting posts 64.

[0034] like Figure 1 , Figure 2 and Figure 6As shown, to achieve support and positioning of the bed frame 6 when unfolded, a left positioning part 7 is provided on the left guardrail 4, and a right positioning part 8 is provided on the right guardrail 5. Specifically, the left positioning part 7 includes a left positioning block 71 fixed at the junction of the left support leg 412 and the left support rod 411, and a left positioning groove 72 is formed on the left positioning block 71. Similarly, the right positioning part 8 includes a right positioning block 81 fixed at the junction of the right support leg 512 and the right support rod 511, and a right positioning groove 82 is formed on the right positioning block 81. When the bed frame 6 unfolds downward to the horizontal position, the two outermost grid rods 63 on the bed frame 6 will be inserted into and supported in the left positioning groove 72 and the right positioning groove 82. Preferably, the left positioning part 7 and the right positioning part 8 are integral structures formed by bending a metal sheet, which are high in strength and durable. Meanwhile, rubber pads (not shown in the figure) are provided on the bottom surfaces of both sides of the bed frame 6. When the bed frame 6 is unfolded, the rubber pads press against the bottom of the left positioning groove 72 and the right positioning groove 82, which can not only buffer and dampen the shock, but also increase the friction, prevent the bed frame 6 from sliding, and reduce noise.

[0035] When the folding bed frame of this utility model is unfolded, as follows: Figure 1 As shown, both the left and right guardrails 4 and 5 extend outwards, roughly perpendicular to the side guardrail 3. The bed frame 6 rotates downwards to a horizontal position, with the left and right positioning parts 7 and 8 providing stable support on both sides, forming a complete sleeping surface. At this point, because the bed frame 6 is horizontal and its sides are positioned within the left and right positioning slots 72 and 82, it prevents the left and right guardrails 4 and 5 from rotating and folding relative to the side guardrail 3, keeping the folding bed frame in its unfolded state. The horizontal position of the bed frame 6 also helps to lock the unfolded state of the folding bed frame. When folding is required, first, lift the bed frame 6 upwards, allowing it to rotate around the third axis C until it is vertically close to the side guardrail 3. At this point, the bed frame 6 no longer obstructs the left and right guardrails 4 and 5, and the user can then pull the left and right guardrails 4 and 5 inwards until they are close to the bed frame 6. Thus, the volume of the entire folding bed frame is greatly reduced, making it easier to store and transport. Moreover, the folding operation is very convenient and quick; simply lift the bed frame 6 and rotate the left guardrail 4 and right guardrail 5 inward.

[0036] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
