Technical Field
[0001] The utility model relates to the technical field of children's products, in particular to a foldable climbing ladder. Background Art
[0002] Children are often unable to reach the table or countertop due to their height limitations, making it inconvenient for them to play with toys on the table or countertop. In this case, a ladder can generally be used. After the child climbs up the ladder and stands on the steps of the ladder, they can play with toys on the table or countertop, which also makes it convenient for the child to interact with the standing adult.
[0003] In order to facilitate storage and storage, the climbing ladder is generally configured to be foldable. When it is needed, the climbing ladder is unfolded; when it is not needed, the climbing ladder is folded to reduce the space it occupies. The existing foldable climbing ladder has a complex structure and is troublesome to fold and unfold. Utility Model Content

[0039] like Figure 1-Figure 6 As shown, a climbing ladder mainly includes: a front leg 1, a rear leg 2, a first pedal 3, a connecting piece 4, an upper frame 5 and a second pedal 12.
[0040] One end of the front leg 1 and the rear leg 2 are both configured as support ends, specifically, the lower ends of the front leg 1 and the rear leg 2 are both support ends. When in use, the climbing ladder is supported on the ground by the support ends of the front leg 1 and the rear leg 2. One end of the rear leg 2 away from its own support end is rotatably connected to the front leg 1. Specifically, the front leg 1 includes a bottom support frame 10 and an upper telescopic frame 11, and the upper telescopic frame 11 is telescopically arranged on the bottom support frame 10, and the front leg 1 and the rear leg 2 each include two support rods 101 arranged at intervals and a bottom rod 102 connected between the two support rods 101. The two bottom rods 102 of the front leg 1 and the rear leg 2 are respectively configured as the support ends of the front leg 1 and the rear leg 2. When in use, the ground is supported by the two bottom rods 102 to ensure the support stability of the climbing ladder. The two support rods 101 of the rear support leg 2 are rotatably connected to the two support rods 101 of the front support leg 1 respectively.
[0041] Among them, an upper frame 5 is provided on the upper telescopic frame 11, the upper frame 5 protrudes on the side away from the rear leg 2, and the upper frame 5 is above the first pedal 3. The two ends of the upper frame 5 are rotatably connected to the front leg 1, so that the upper frame 5 can be unfolded relative to the front leg 1 or folded onto the front leg 1. After folding, the upper frame 5 is attached to the front leg 1, and occupies a small space. The upper frame 5 plays a role in protecting children, and prevents children from falling when they stand on the first pedal 3 to play. The telescopic adjustment of the upper telescopic frame 11 realizes the height adjustment of the upper frame 5, so that the upper frame 5 can be suitable for children of different heights.
[0042] The first pedal 3 (i.e., the upper pedal) is rotatably connected to the front leg 1, one end of the connecting member 4 is rotatably connected to the first pedal 3, and the other end of the connecting member 4 is rotatably connected to the rear leg 2. During use, when the first pedal 3 flips forward relative to the front leg 1, the first pedal 3 can drive the rear leg 2 to rotate relative to the front supporting leg through the connecting member 4, and the supporting end of the rear leg 2 moves closer to the supporting end of the front leg 1.
[0043] In this embodiment, the first pedal 3 is rotatably connected to the front leg 1, one end of the connecting member 4 is rotatably connected to the first pedal 3, and the other end of the connecting member 4 is rotatably connected to the rear leg 2. When the climbing ladder needs to be folded, the first pedal 3 can be flipped forward, and the first pedal 3 drives the rear leg 2 to move closer to the front leg 1 through the connecting member 4, so that the folding is convenient.
[0044] Specifically, Figure 1-Figure 3 as well as Figure 6 As shown, the climbing ladder of this embodiment has an unfolded state and a folded state, and a limiter 20 is provided on the rear leg 2, and the limiter 20 is a limiter bracket, and the two ends of the limiter 20 are respectively fixedly connected to the rear leg 2. When the climbing ladder is in the unfolded state, the first pedal 3 abuts against the limiter 20 to prevent the first pedal 3 from continuing to move downward; when the climbing ladder is in the folded state, the first pedal 3 is detached from the limiter 20. More specifically, when the supporting ends of both the front leg 1 and the rear leg 2 are supported on a horizontal plane, and when the climbing ladder is in the unfolded state, the first pedal 3 is horizontally arranged, and the connecting member 4 at this time is also horizontally arranged. The connecting member 4 of this embodiment can be, but is not limited to, a connecting iron sheet. Among them, when the climbing ladder is switched to the folded state, the first pedal 3 flips forward to be parallel to the front leg 1, and the rear leg 2 is attached to the front leg 1, and the overall space occupied is small. A second pedal 12 (i.e., a lower pedal) is also provided on the bottom support frame 10 on the front leg 1 . The second pedal 12 is located below the first pedal 3 , and a child can climb onto the first pedal 3 via the second pedal 12 .
[0045] After the climbing ladder of this embodiment is folded, the rear leg 2 is close to the front leg 1, the front leg 1, the rear leg 2 and the first pedal 3 are all parallel, the upper telescopic frame 11 of the front leg 1 can be retracted into the bottom support frame 10, and the upper frame 5 can be rotated and folded onto the front leg 1. After folding, the volume is small and the space occupied is small.
[0046] During use, when the climbing ladder needs to be folded, the first pedal 3 is first flipped forward, and the first pedal 3 drives the rear legs 2 through the connecting member 4, and the rear legs 2 rotate and move closer relative to the front legs 1 until the rear legs 2 are attached to the front legs 1, and the rear legs 2 and the first pedal 3 are folded. Then, the upper frame 5 is flipped downward so that the upper frame 5 is folded onto the front legs 1; finally, the upper telescopic rod is retracted downward relative to the bottom support frame 10, so that the upper telescopic rod and the upper frame 5 move downward as a whole, and the overall folding of the climbing ladder is completed.
[0047] In this solution, the overall structure of the climbing ladder is simple, and it is convenient to fold and unfold. After folding, the ladder is compact and occupies little space.
