Description

[Technical Field]

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

[0002] Currently, with the improvement of people's living standards, more and more bed rails are being used in the lives of infants and young children. Bed rails are installed on the bed frame to prevent children from rolling over and falling off the bed while sleeping, thus protecting them.

[0003] Chinese Patent Publication No. (CN213345024U) discloses a splicing structure for a bed rail. This splicing structure uses splicing parts to abut against the inner sides of two adjacent uprights, and then bolts are inserted to connect the adjacent uprights. In this splicing structure, the splicing parts only contact the inner sides of the uprights, resulting in a small contact area and low connection strength.

Detailed Implementation Methods

[0046] The present invention will be further described below with reference to the accompanying drawings:

[0047] like Figure 1 , Figure 5 and Figure 21 As shown, a bed rail includes a first frame 1 and a second frame 2 and a third frame 3 perpendicular to the first frame 1. A cover 4 is attached to each of the first frame 1, second frame 2, and third frame 3. The first frame 1, second frame 2, and third frame 3 extend along the edge of the bed frame 100 to form a protective space 200. Support members 5 for fixing the three frames to the bed frame 100 are attached to the first frame 1, second frame 2, and third frame 3. When the bed rail is installed and fixed to the bed frame 100, the cover 4 blocks the sides of the bed frame 100, preventing infants and toddlers in the protective space 200 from falling off the bed while rolling over, ensuring safety. Since the first frame 1, the second frame 2, and the third frame 3 extend along different edges of the bed frame 100, a first connector 61 must be provided between the first frame 1 and the second frame 2 to fix them together, and a second connector 62 must also be provided between the first frame 1 and the third frame 3 to fix them together. This ensures that the first frame 1, the second frame 2, and the third frame 3 form a whole after being connected to the bed frame 100, thereby enhancing the stability of the bed rails on the bed frame 100 and ensuring safety.

[0048] In this embodiment, as Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9As shown, the first connector 61 includes a first connecting sleeve 611 that can be fitted onto the upper ends of the first frame 1 and the second frame 2. The first connecting sleeve 611 can wrap around the corresponding parts of the upper ends of the first frame 1 and the second frame 2, increasing the connection contact area. At the same time, the first connecting sleeve 611 is provided with a plurality of downwardly extending first insertion posts 612. One end of the first frame 1 and the second frame 2 are provided with first insertion grooves 613. When the first connecting sleeve 611 is fitted onto the upper ends of the first frame 1 and the second frame 2, the first insertion posts 612 are also inserted into the first insertion grooves 613, further increasing the connection contact area and firmly connecting the upper parts of the first frame 1 and the second frame 2 together. In this embodiment, the second connector 62 also includes a second connecting sleeve 621 that can be fitted onto the first frame 1 and the third frame 3. The second connecting sleeve 621 is provided with a plurality of downwardly extending second insertion posts 622. The other end of the first frame 1 and the third frame 3 are provided with second insertion grooves 623 that can be inserted and cooperate with the second insertion posts 622. The second connecting sleeve 621 is inserted into the second insertion slot 623 through the second insertion post 622, and at the same time, it wraps around the corresponding upper parts of the first frame 1 and the third frame 3 through the sleeve method, so that the first frame 1 and the third frame 3 are also connected very firmly.

[0049] like Figure 1 , Figure 5 and Figure 7 As shown, the first frame 1 includes a front vertical bar 11 and a rear vertical bar 12 spaced apart from each other. The upper ends of the front vertical bar 11 and the rear vertical bar 12 are connected to a first horizontal stop 13 that can be raised and lowered relative to them. The lower ends of the front vertical bar 11 and the rear vertical bar 12 are fixedly provided with a first lower horizontal bar 14 connecting the two. The second frame 2 includes a second left vertical bar 21 and a second right vertical bar 22 spaced apart from each other. The upper ends of the second left vertical bar 21 and the second right vertical bar 22 are connected to a second horizontal stop 23 that can be raised and lowered relative to them. The lower ends of the second left vertical bar 21 and the second right vertical bar 22 are fixedly provided with a second lower horizontal bar 24 connecting the two. The third frame 3 includes a third left vertical bar 31 and a third right vertical bar 32 spaced apart from each other. The upper ends of the third left vertical bar 31 and the third right vertical bar 32 are connected to a third horizontal stop 33 that can be raised and lowered relative to them. The lower ends of the third left vertical bar 31 and the third right vertical bar 32 are fixedly provided with a third lower horizontal bar 34 connecting the two. The first horizontal stop 13, the second horizontal stop 23 and the third horizontal stop 33 can be raised and lowered, making it convenient for users to take infants out of or into the bed.

[0050] like Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9As shown, the first connecting sleeve 611 is fitted onto the upper ends of the second left vertical rod 21 and the front vertical rod 11 to wrap around the upper ends of the second left vertical rod 21 and the front vertical rod 11. The first insertion slots 613 are provided on the upper ends of the second left vertical rod 21 and the front vertical rod 11. There are two first insertion slots 613 on the upper end of the second left vertical rod 21, and a first connecting hole 614 is provided between the two first insertion slots 613. There are also two first insertion slots 613 on the upper end of the front vertical rod 11, and a second connecting hole 615 is provided between the two first insertion slots 613. The first connecting sleeve 611 has a third connecting hole 616 opposite to the first connecting hole 614 and a fourth connecting hole 617 opposite to the second connecting hole 615. When the first insertion post 612 is inserted into the corresponding first insertion slot 613, a first screw 618 is provided between the first connecting hole 614 and the third connecting hole 616, and between the second connecting hole 615 and the fourth connecting hole 617. Therefore, the first connecting sleeve 611 not only wraps around the upper ends of the second left vertical rod 21 and the front vertical rod 11 from all sides, but also inserts into the upper ends of the second left vertical rod 21 and the front vertical rod 11 through multiple first insertion pins 612. Furthermore, the first connecting sleeve 611 is locked to the upper ends of the second left vertical rod 21 and the front vertical rod 11 by first screws 618, further ensuring the stability of the connection between the first frame 1 and the second frame 2. In addition, in order to ensure a very stable connection between the first frame 1 and the third frame 3, the second connecting sleeve 621 is fitted onto the upper ends of the third left vertical rod 31 and the rear vertical rod 12 to wrap around the upper ends of the third left vertical rod 31 and the rear vertical rod 12. The second insertion slot 623 is provided at the upper end of the third left vertical rod 31 and the upper end of the rear vertical rod 12. There are two second insertion slots 623 at the upper end of the third left vertical rod 31, and a fifth connecting hole 624 is provided between the two second insertion slots 623. There are two second insertion slots 623 at the upper end of the rear vertical rod 12, and a sixth connecting hole 625 is provided between the two second insertion slots 623. The second connecting sleeve 621 is provided with a seventh connecting hole 626 opposite to the fifth connecting hole 624 and an eighth connecting hole 627 opposite to the sixth connecting hole 625. When the second insertion post 622 is inserted into the corresponding second insertion slot 623, a second screw 628 is provided between the fifth connecting hole 624 and the seventh connecting hole 626, and between the sixth connecting hole 625 and the eighth connecting hole 627. Similarly, the second connecting sleeve 621 not only wraps around the upper ends of the third left vertical rod 31 and the rear vertical rod 12 from all sides, but also inserts into the depths of the upper ends of the third left vertical rod 31 and the rear vertical rod 12 through multiple second plug-in pins 622, and further secures the second connecting sleeve 621 to the upper ends of the third left vertical rod 31 and the rear vertical rod 12 through the second screws 628, thereby further ensuring the stability of the connection between the first frame 1 and the third frame 3.

[0051] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 18 and Figure 19 As shown, the support member 5 includes a first support frame 51 connected to the front vertical bar 11 and the second left vertical bar 21, and a second support frame 52 connected to the rear vertical bar 12 and the third left vertical bar 31. The first support frame 51 includes a first column 511 that can be inserted into the second left vertical bar 21 and a front column 512 that can be inserted into the front vertical bar 11. The lower end of the first column 511 is welded to a first base plate 513 that can be pressed down by the mattress 300. The lower end of the front column 512 is welded to a front base plate 514 that can be pressed down by the mattress 300. A first connecting plate 515 that forms a triangle with the first base plate 513 is welded between the front base plate 514 and the first base plate 513. The first base plate 513 and the front base plate 514 are perpendicular to each other and welded together. The second support frame 52 includes a second upright 521 that can be inserted into the third left vertical bar 31 and a rear upright 522 that can be inserted into the rear vertical bar 12. The lower end of the second upright 521 is welded to a second base plate 523 that can be pressed down by the mattress 300. The lower end of the rear upright 522 is welded to a rear base plate 524 that can be pressed down by the mattress 300. A second connecting plate 525 that forms a triangle with the second base plate 523 is welded between the rear base plate 524 and the second base plate 523. The second base plate 523 and the rear base plate 524 are perpendicular to each other and welded together. Therefore, the first support frame 51 and the second support frame 52 are both integral structures. The front base plate 514, the first base plate 513 and the first connecting plate 515 form a triangle that can be pressed down by the mattress 300. The rear base plate 524, the second base plate 523 and the second connecting plate 525 also form a triangle that can be pressed down by the mattress 300, thereby allowing the bed rail to be stably installed on the bed frame 100. Furthermore, the first upright post 511 and the front upright post 512 are fixedly connected together by welding the first base plate 513 and the front base plate 514. Simultaneously, the first upright post 511 is inserted into the second left vertical rod 21, and the front upright post 512 is inserted into the front vertical rod 11. This structure ensures a very secure connection between the lower parts of the front vertical rod 11 and the second left vertical rod 21. Similarly, the lower parts of the rear vertical rod 12 and the third left vertical rod 31 are also very securely connected, ensuring the stability of the entire bed rail structure and preventing it from wobbling.

[0052] In this embodiment, the first upright post 511 can also be inserted into the rear vertical rod 12. When the first upright post 511 is inserted into the rear vertical rod 12, the front upright post 512 is inserted into the third left vertical rod 31. Furthermore, the second upright post 521 can also be inserted into the front vertical rod 11. When the second upright post 521 is inserted into the front vertical rod 11, the rear upright post 522 is inserted into the second left vertical rod 21. Therefore, when installing and assembling the bed rail, the first support frame 51 can be connected to the lower part of the first frame 1 and the second frame 2, or to the lower part of the first frame 1 and the third frame 3. Similarly, the second support frame 52 can be connected to the lower part of the first frame 1 and the third frame 3, or to the lower part of the first frame 1 and the second frame 2. Users do not need to distinguish between the first support frame 51 and the second support frame 52 when installing them; they can directly perform the insertion and assembly operation, making the bed rail assembly convenient and quick.

[0053] like Figure 5 , Figure 18 and Figure 19 As shown, the first base plate 513, the second base plate 523, the front base plate 514 and the rear base plate 524 are provided with arched ribs 55 along their length to enhance the structural strength of the first base plate 513, the second base plate 523, the front base plate 514 and the rear base plate 524 and prevent deformation caused by children frequently shaking the bed rails.

[0054] like Figure 5 and Figure 7 As shown, the first upright post 511 is slidably connected to the second left vertical rod 21, and a first adjustment mechanism 71 for adjusting their relative height is provided between them. The front upright post 512 is slidably connected to the front vertical rod 11, and a second adjustment mechanism 72 for adjusting their relative height is provided between them. The second upright post 521 is slidably connected to the third left vertical rod 31, and a third adjustment mechanism 73 for adjusting their relative height is provided between them. The rear upright post 522 is slidably connected to the rear vertical rod 12, and a fourth adjustment mechanism 74 for adjusting their relative height is provided between them. By adjusting the corresponding height, it can accommodate mattresses of different thicknesses, making the bed rail suitable for a wide range of applications. The specific structure of the first adjustment mechanism 71 will be described in detail in the following section.

[0055] like Figure 15 , Figure 18 and Figure 19As shown, the first adjustment mechanism 71 includes a plurality of adjustment holes 711 vertically spaced on the first column 511. An adjustment column 712 is slidably disposed inside the second lower crossbar 24, passing through the side wall of the second left vertical bar 21 and capable of engaging or disengaging with the adjustment holes 711. A sliding seat 713 is disposed inside the second lower crossbar 24. The adjustment column 712 is fixedly connected to the sliding seat 713. A toggle button 714 is provided on the sliding seat 713 and exposed on the second lower crossbar 24. A first return spring 715 is also provided inside the second lower crossbar 24 to push the sliding seat 713 and the adjustment column 712 to slide back to their original positions. When it is necessary to adjust the relative height between the first column 511 and the second left vertical rod 21, push the toggle button 714 to disengage the adjusting column 712 from the adjusting hole 711. Once disengaged, the second left vertical rod 21 can be slid upwards. When the desired position is reached, release the toggle button 714, and the first return spring 715 will push the sliding seat 713 to return to its original position, thereby causing the adjusting column 712 to re-engage with the other adjusting hole 711. The entire adjustment process is very convenient and quick. In this embodiment, the second adjusting mechanism 72, the third adjusting mechanism 73, and the fourth adjusting mechanism 74 adopt the same structure as the first adjusting mechanism 71, and will not be described again in this document.

[0056] like Figure 15 As shown, the sliding seat 713 has a recess 713a, and the bottom of the recess 713a has a through hole 713b. The head of the adjusting column 712 passes through the through hole 713b. The adjusting column 712 has a contact surface 712a that abuts against the bottom of the recess 713a after it passes through the through hole 713b. A screw 713c is fixedly connected to the sliding seat 713, which abuts against the tail of the adjusting column 712 and fixes the adjusting column 712 in the sliding seat 713. This structure allows the adjusting column 712 to be made of metal to fit the first column 511, which uses metal tubing, thereby increasing wear resistance. The sliding seat 713 can be injection molded, reducing costs. During assembly, simply insert the adjusting column 712 into the sink 713a. The front end of the adjusting column 712 extends out and the abutting surface 712 abuts against the bottom of the sink 713a. The tail end of the adjusting column 712 is then sealed with screws 713c, thus positioning the adjusting column 712. The assembly is very convenient and quick.

[0057] like Figure 7 , Figures 11 to 14As shown, the second horizontal stop 23 includes a second upper horizontal bar 231. One end of the second upper horizontal bar 231 is connected to a left connecting seat 232. A left sliding sleeve 233 that can slide on the second left vertical bar 21 is connected to the left connecting seat 232. The other end of the second upper horizontal bar 231 is connected to a right connecting seat 234. A right sliding sleeve 235 that can slide on the second right vertical bar 22 is connected to the right connecting seat 234. A left locking structure 236 for locking the position of the left sliding sleeve 233 is provided between the left connecting seat 232 and the second left vertical bar 21. A right locking structure 237 for locking the position of the right sliding sleeve 235 is provided between the right connecting seat 234 and the second right vertical bar 22. When it is necessary to take the baby out of or into the bed, first unlock the left locking structure 236 and the right locking structure 237. Then, slide the left sliding sleeve 233 downward on the second left vertical bar 21 and the right sliding sleeve 235 downward on the second right vertical bar 22. This lowers the height of the second upper horizontal bar 231, making it easier for the user to get into the bed. The left locking structure 236 will be described in detail in the following section. The right locking structure 237 can adopt the same structure as the left locking structure 236, and will not be described again in this article. At the same time, the first horizontal stop 13 and the third horizontal stop 33 can also adopt the same structure as the second horizontal stop 23, and will not be described again in this article.

[0058] like Figures 11 to 14 As shown, the left locking structure 236 includes a locking hole 2361 on the left sliding sleeve 233, a V-shaped spring piece 2362 inside the second left vertical rod 21, a locking pin 2363 on the spring piece 2362 that passes through the side wall of the second left vertical rod 21 and engages with the locking hole 2361, a sliding seat 2364 slidably disposed inside the left connecting seat 232, and a pushing pin 2365 on the sliding seat 2364 that can push the locking pin 2363 out of the locking hole 2361 when it slides to one side of the second left vertical rod 21. The base 232 has an operating block 2366 exposed on its lower side and slidable relative to it. The operating block 2366 has an inclined groove 2367, and the sliding base 2364 has a protrusion 2368 inserted into the inclined groove 2367. When the operating block 2366 slides relative to the left connecting base 232, the groove wall of the inclined groove 2367 pushes the protrusion 2368, causing the sliding base 2364 to slide. A second return spring 2369 is provided between the left connecting base 232 and the operating block 2366 to push the operating block 2366 back to its original position. During unlocking, pushing the operating block 2366 to slide causes the groove wall of the inclined groove 2367 to push the protrusion 2368, causing the sliding base 2364 to slide towards the second left vertical rod 21. The pushing post 2365 on the sliding base 2364 then pushes the locking post 2363 out of the locking hole 2361 on the left sliding sleeve 233, thus unlocking the left locking structure 236. Figures 11 to 14As shown, to avoid misoperation, the upper side of the left connecting seat 232 is provided with an exposed pressing block 236a. The pressing block 236a is provided with a downwardly extending extension post 236b. The extension post 236b is provided with a protruding blocking block 236c on one side. A relief groove 236d is formed between the blocking block 236c and the pressing block 236a. The sliding seat 2364 is provided with a protrusion 236e that can be opposite to the blocking block 236c or the relief groove 236d. A third return spring 236f is provided between the left connecting seat 232 and the pressing block 236a, which can push the pressing block 236a to return to its original position. When the pressing block 236a is not pressed, the protrusion 236e is opposite to the blocking block 236c. Even if the operating block 2366 is pressed, the blocking block 236c can abut against the protrusion 236e, thus preventing the sliding seat 2364 from sliding towards the second left vertical rod 21 and preventing unlocking. However, when the pressing block 236a is pressed, causing the clearance groove 236d to be opposite the protrusion 236e, the protrusion 236e can enter the clearance groove 236d. Therefore, pressing the operating block 2366 simultaneously allows the sliding seat 2364 to slide towards the second left vertical rod 21, thereby pushing the locking pin 2363 out of the locking hole 2361 and completing the unlocking. Therefore, both the pressing block 236a and the operating block 2366 must be pressed simultaneously during unlocking. This prevents accidental unlocking by infants or young children due to accidental contact with either component, ensuring safety. To make the upward sliding and locking operation of the second horizontal stop 23 simpler and faster, the upper end of the inner wall of the left sliding sleeve 233 is provided with an inclined surface 233a that can squeeze the locking post 2363 into the second left vertical rod 21 when it slides upward. Specifically, when the left sliding sleeve 233 slides upward, the inclined surface 233a will touch and push the locking post 2363 to move, and the spring piece 2362 will deform. When the sliding sleeve 233 slides to the locking hole 2361 on it and aligns with the locking post 2363, the spring piece 2362 will elastically return and push the locking post 2363 into the locking hole 2361 to complete the locking. Therefore, when raising the second horizontal stop 23, the second horizontal stop 23 can be lifted directly without operating the pressing block 236a and the operating block 2366, making the raising and locking operation of the second horizontal stop 23 simpler.

[0059] like Figure 13 , Figure 16 and Figure 17As shown, the left connecting seat 232 is provided with a protruding fixing post 238, and the end of the fixing post 238 is provided with a protruding cap 239 protruding from its outer circumference. The second upper crossbar 231 is provided with a locking groove 230 that can be engaged from top to bottom with the protruding cap 239 and the fixing post 238, which facilitates the disassembly of the second upper crossbar 231. At the same time, when the locking groove 230 is engaged with the protruding cap 239 and the fixing post 238, the second upper crossbar 231 can rotate relative to the protruding cap 239 and the fixing post 238. This means that when lowering the second crossbar 23, it is not necessary to unlock the left locking structure 236 and the right locking structure 237 at the same time. For example, after unlocking the left locking structure 236, the left sliding sleeve 233 and the left connecting seat 232 can be slid directly. At this time, the second upper crossbar 231 and the left connecting seat 232 rotate relative to each other at the fixing post 238, avoiding interference and making the operation of lowering the second crossbar 23 more convenient and quick.

[0060] like Figure 5 , Figure 7 and Figure 20 As shown, to ensure a more stable installation of the bed rails onto the bed frame 100, a third support frame 53 is connected to the second right vertical bar 22. The third support frame 53 includes a third column 531 slidably connected to the second right vertical bar 22. A third base plate 532, which can be pressed down by the mattress 300, is welded to the lower end of the third column 531. A fifth adjustment mechanism 75 is provided between the third column 531 and the second right vertical bar 22 to adjust their relative height. A fourth support frame 54 is also connected to the third right vertical bar 32. The fourth support frame 54 includes a fourth column 541 slidably connected to the third right vertical bar 32. A fourth base plate 542, which can be pressed down by the mattress 300, is welded to the lower end of the fourth column 541. A sixth adjustment mechanism 76 is provided between the fourth column 541 and the third right vertical bar 32 to adjust their relative height. The fifth adjustment mechanism 75 and the sixth adjustment mechanism 76 can also adopt the same structure as the first adjustment mechanism 71, which will not be described in detail here.

[0061] like Figure 7 and Figure 20 As shown, in order to enhance the structural strength of the third base plate 532 and the fourth base plate 542, arched ribs 55 are provided on the third base plate 532 and the fourth base plate 542.

[0062] like Figures 22 to 25Another embodiment of the structure is shown. The difference between this structure and the aforementioned bed rail structure is that: the inner sides of the front vertical bar 11, rear vertical bar 12, second left vertical bar 21, second right vertical bar 22, third left vertical bar 31 and third right vertical bar 32 are all provided with inner vertical bars 91 spaced apart from them; the first horizontal stop 13, second horizontal stop 23 and third horizontal stop 33 are respectively slidably connected to the corresponding inner vertical bars 91 and can move up and down; the first lower horizontal bar 14, second lower horizontal bar 24 and third lower horizontal bar 34 are fixedly connected to the lower end of the corresponding inner vertical bar 91. In this embodiment, the first column 511 is fixedly connected to a first plastic sleeve 516, and the first column 511 is slidably connected to the second left vertical rod 21 through the first plastic sleeve 516. The front column 512 is fixedly connected to a second plastic sleeve 517, and the front column 512 is slidably connected to the front vertical rod 11 through the second plastic sleeve 517. The first adjustment mechanism 71 includes a plurality of adjustment slots 7a vertically spaced on the first plastic sleeve 516. An adjustment rod 7b is slidably provided inside the second lower horizontal rod 24, passing through the side wall of the second left vertical rod 21 and capable of engaging or disengaging with the adjustment slots 7a. A toggle block 7c is slidably connected to the second lower horizontal rod 24, and the toggle block 7c is fixedly connected to the adjustment rod 7b. A fourth return spring 7d is also provided inside the second lower horizontal rod 24 to push the adjustment rod 7b to slide back to its original position. Since the adjustment slots 7a are located on the first plastic sleeve 516, the adjustment rod 7b can also be made of plastic and integrally injection molded with the toggle block 7c. In addition, a connecting rod 92, which can be pressed down by the mattress 300, is detachably connected between the fourth base plate 542 and the third base plate 532. One end of the connecting rod 92 is fitted onto the fourth base plate 542, and the other end is fitted onto the third base plate 532, making the bed rail more stable when installed on the bed frame 100. Furthermore, an upper connecting rod 93 is detachably connected between the upper ends of the second right vertical bar 22 and the third right vertical bar 32. When the upper connecting rod 93 is connected between the upper ends of the second right vertical bar 22 and the third right vertical bar 32, it can further reduce the swaying of the bed rail and ensure that the overall structure of the bed rail is more stable.
