Description

[Technical field]

[0001] The utility model relates to a foldable bed guardrail. [Background technology]

[0002] Bed guardrails are common products for infants and young children during their growth process, used to prevent infants and young children from falling off the bed. During installation, the lower support is pressed under the mattress, and the guardrail frame is erected on one side of the bed. After a cloth cover is put on the guardrail frame, it can prevent infants and young children from rolling off. In order to facilitate taking infants and young children off the bed, the guardrail frame generally includes a lower frame and an upper frame. The upper frame can be rotated relative to the lower frame to unfold or fold. Therefore, the guardrail frame is set as a foldable structure.

[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0029] like Figures 1 to 6 As shown, a foldable bed guardrail comprises a lower support member 1 which can be pressed by a mattress, a guardrail frame 2 being connected to the lower support member 1, the guardrail frame 2 comprising a lower frame body 21 connected to the lower support member 1 and an upper frame body 22 which can be rotated and unfolded or rotated and folded relative to the lower frame body 21, the lower frame body 21 comprises two lower vertical rods 211 spaced from each other, a lower cross rod 212 is disposed at the lower end of the lower vertical rod 211, the upper frame body 22 comprises upper vertical rods 221 spaced from each other, an upper cross rod 222 is disposed at the upper end of the upper vertical rod 221, the upper vertical rod 221 and the upper cross rod 222 are integrally bent and formed into a U-shaped integral structure with an opening downward, and can be formed by directly bending a pipe fitting. The lower end of the lower vertical rod 211 is provided with a lower joint seat 213, and the lower end of the upper vertical rod 221 is provided with an upper joint seat 223 rotatably connected to the lower joint seat 213. In this embodiment, the lower joint seat 213 includes an inner seat body 2131 and an outer seat body 2132 connected to the upper end of the lower vertical rod 211, and the upper joint seat 223 is arranged between the inner seat body 2131 and the outer seat body 2132. A locking structure 3 for locking the upper joint seat 223 and the lower joint seat 213 is provided between the upper joint seat 223 and the lower joint seat 213, and an unlocking holding component 4 is also provided between the upper joint seat 223 and the lower joint seat 213 to maintain the unlocking state of the upper joint seat 223 and the lower joint seat 213 when the locking structure 3 is unlocked. Therefore, when the locking structure 3 is unlocked, its unlocking state will be maintained by the unlocking holding component 4, and the user can free his hands to pull the upper frame 22, and there is no need to apply an unlocking force to the locking structure 3 all the time, so the folding of the bed guardrail is very convenient and quick.

[0030] like Figures 3 to 6As shown, the locking structure 3 includes a locking groove 31 arranged on the lower joint seat 213 along the radial direction, the upper joint seat 223 is provided with a sliding block 32 exposed and capable of sliding therein, the sliding block 32 is provided with a locking column 33 which can engage with or disengage from the locking groove 31 in the transverse direction, the lower joint seat 213 is provided with a first making way groove 34 which can make way for the locking column 33 when the locking column 33 is disengaged from the locking groove 31 and the upper joint seat 223 rotates relative to the lower joint seat 213, the lower end of the sliding block 32 is provided with a connecting portion 35 which can be connected to the unlocking retaining assembly 4 to prevent the sliding block 32 from sliding back to the original position when the locking column 33 is disengaged from the locking groove 31, and a first spring 36 which can push the sliding block 32 to slide back to the original position is provided between the sliding block 32 and the upper joint seat 223. When unlocking, the sliding block 32 is pressed, and the locking column 33 on the sliding block 32 is disengaged from the locking groove 31. Once the locking column 33 is disengaged from the locking groove 31, the connecting portion 35 at the lower end of the sliding block 32 is connected to the unlocking holding assembly 4, thereby preventing the sliding block 32 from being pushed back by the first spring 36. At this time, the user can release the sliding block 32, thereby freeing up his hands to turn the upper frame 22 to rotate and fold. When the upper joint seat 223 rotates, the locking column 33 moves in the first yielding groove 34 on the lower joint seat 213, so that the upper frame 22 can be folded smoothly. For bed guardrails that are long and cannot press the sliding block 32 of the locking structures 3 on both sides at the same time, the user can unlock the locking structure 3 on one side, free up his hands to unlock the locking structure 3 on the other side, and finally turn the upper frame 22 to fold.

[0031] like Figure 6 As shown, the upper joint seat 223 is rotatably connected to the lower joint seat 213 via a connecting shaft 5, the sliding block 32 is provided with a strip groove 37 for the connecting shaft 5 to pass through, the first spring 36 is located in the strip groove 37 with one end abutting against the groove wall of the strip groove 37 and the other end abutting against the connecting shaft 5.

[0032] like Figure 4 , Figures 6 to 8As shown, the connecting portion 35 includes a protruding block 351 provided at the lower end of the sliding block 32 and protruding on both sides, the upper surface of the protruding block 351 and the side surface of the sliding block 32 form a step 352, the unlocking and holding component 4 includes a sliding column 41 that can move laterally in the lower joint seat 213, the sliding column 41 is provided with an inclined surface 42 that can be pressed by the protruding block 351 when the sliding block 32 slides, so that the sliding column 41 slides relative to the lower joint seat 213, the protruding block 351 is provided with an inclined wall 353 that abuts against the inclined surface 42, and the sliding column 41 and the lower joint seat 213 are interlocked. A return spring 43 is also provided which can push the sliding column 41 to slide and return to its original position. The sliding column 41 is provided with a support surface 44 which can abut against the step 352 to prevent the sliding block 32 from sliding and returning to its original position after being pushed and returned to its original position by the return spring 43. The sliding column 41 is provided with an inclined surface 45 which can be pushed by the protruding block 351 when the upper joint seat 223 is rotated and unfolded relative to the lower joint seat 213, so that the sliding column 41 slides relative to the lower joint seat 213. The upper joint seat 223 is provided with a second making way groove 224 along the circumferential direction which can make way for the sliding column 41 when the upper joint seat 223 is rotated and folded relative to the lower joint seat 213. When the sliding block 32 is pressed and slides, the inclined wall 353 on the protruding block 351 pushes the inclined surface 42 on the sliding post 41, so that the sliding post 41 moves laterally and compresses the return spring 43. When the step 352 on the protruding block 351 moves to the lower side of the sliding post 41, the return spring 43 pushes the sliding post 41 to slide and return, and the abutting surface 44 on the sliding post 41 abuts against the step 352, thereby preventing the sliding block 32 from sliding and returning under the action of the first spring 36. At this time, the locking post 33 and the locking groove 31 are disengaged. The detached state is maintained, and the user can no longer press the sliding block 32, thereby freeing up a hand to operate the locking structure 3 on the other side to unlock or pull the upper frame 22 to rotate and fold. During the rotation and folding process, the second clearance groove 224 on the upper joint seat 223 makes way for the protruding sliding column 41 to avoid interference, and because the abutting surface 44 is disengaged from the step 352, the sliding block 32 will be slightly reset under the action of the first spring 36 until the locking column 33 on the sliding block 32 abuts against the outer side wall of the first clearance groove 34. When the upper frame 22 needs to be unfolded, the upper frame 22 is rotated in the opposite direction, and the side of the protruding block 351 will push the inclined surface 45 on the sliding column 41, thereby pushing the sliding column 41 to slide and compress the reset spring 43. When the locking column 33 is rotated to align with the locking groove 31, the first spring 36 pushes the sliding block 32 to completely reset, so that the locking column 33 is engaged with the locking groove 31 again, and the sliding column 41 is also completely reset under the action of the reset spring 43.

[0033] like Figures 3 to 6As shown, the upper joint seat 223 is provided with a guide hole 225 along the radial direction for the locking column 33 to slide inside, so that the sliding block 32 slides smoothly, and the lower joint seat 213 is detachably connected to the decorative cover 214, and one end of the return spring 43 rests on the decorative cover 214, and the other end rests on the sliding column 41.

[0034] like Figure 3 and Figure 5 As shown, the lower support member 1 comprises a U-shaped frame 11 that can be pressed by a mattress, an upwardly extending support rod 12 is provided at the opening of the U-shaped frame 11, the lower vertical rod 211 is sleeved on the support rod 12 and can slide up and down relative to the support rod 12, and a locking device 6 that can lock the relative position of the lower vertical rod 211 and the support rod 12 is provided on the lower cross bar 212. After unlocking the locking device 6, the user can adjust the height of the guardrail frame 2 to adapt to mattresses of different thicknesses. The locking device 6 can adopt a conventional structure of a bayonet pin and a bayonet hole, which will not be described in detail here.

[0035] The embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
