Technical Field

[0001] The present invention relates to the technical field of children's sanitary products, and in particular to a folding toilet ladder and a folding method thereof. Background Art

[0002] Most existing household toilets are generally designed to fit the size of adults. Their seat rings are too high and too large for children, making it inconvenient for children to use. Moreover, due to their short height, children cannot sit on the toilet by themselves and need the assistance of adults, so it is rather inconvenient. Therefore, some toilet ladders have emerged on the market. Generally, they include a seat cushion and a heightening ladder fixedly connected. The seat cushion is used to be placed on the toilet to fit the size of a two-way toilet. Children can sit on the seat cushion through the heightening ladder to use the toilet independently. The heightening ladder can also be used for children to step on to increase their height for washing on the washbasin.

[0003] However, generally, the pedal of the existing toilet ladder is connected to the support frame by a buckle. After being assembled, its shape is fixed and it cannot be folded, occupying a large space. During transportation, it is generally disassembled into multiple parts for storage.

[0034] The following further details the specific implementation manners of the present invention with reference to the drawings.

[0035] Embodiment 1:

[0036] A folding toilet ladder provided in this embodiment, as Figures 1 - 8 shown, includes a toilet seat 1, a ladder frame, and a pedal 4. The toilet seat 1 is rotatably connected to the top of the ladder frame. The toilet seat 1 is used to be placed on an adult toilet so that children can sit on it to use the toilet. The ladder frame is used to solve the problem of children climbing and independently getting on and off an adult flush toilet. By climbing on the ladder frame, children can easily sit on the toilet seat 1.

[0037] As Figure 1 and Figure 2As shown in the figure, the ladder rack includes a main connecting frame 2, a rear connecting frame 3 and a bottom connecting frame 5. The pedal 4 is rotatably connected to the top end of the rear connecting frame 3 and is detachably installed on the main connecting frame 2. Preferably, the middle parts on the left and right sides of the pedal 4 are connected to the middle part of the main connecting frame 2 in the vertical position. When the pedal 4 is installed on the main connecting frame 2, the pedal 4 is horizontally arranged to facilitate children to step on. The bottom end of the rear connecting frame 3 is rotatably connected to the rear side of the bottom connecting frame 5, and the front side of the bottom connecting frame 5 is rotatably connected to the bottom end of the main connecting frame 2. The above-mentioned rotatable connection can be connected through a hinge seat and a rotating shaft.

[0038] In the ladder rack of this embodiment, by including the main connecting frame 2, the rear connecting frame 3 and the bottom connecting frame 5, when the pedal 4 is installed on the main connecting frame 2, as Figure 2 shown, a trapezoidal support structure is formed among the pedal 4, the main connecting frame 2, the rear connecting frame 3 and the bottom connecting frame 5, and the structural stability is strong. Since the pedal 4 is rotatably connected to the top end of the rear connecting frame 3, the bottom end of the rear connecting frame 3 is rotatably connected to the rear side of the bottom connecting frame 5, and the front side of the bottom connecting frame 5 is rotatably connected to the bottom end of the main connecting frame 2, the pedal 4, the main connecting frame 2, the rear connecting frame 3 and the bottom connecting frame 5 can be relatively folded. And the toilet seat 1 is rotatably connected to the top end of the ladder rack, so that the toilet seat 1 can be folded relative to the ladder rack, further increasing the foldability of the folding toilet ladder, thereby reducing the occupied space of the ladder rack, and making the folding toilet ladder of this embodiment easy to fold and store when idle.

[0039] Compared with the existing assembled toilet ladder, the folding toilet ladder of this embodiment fixes the pedal through three connecting frames. The connecting frames are connected end to end and rotate in a staggered manner to achieve quick folding and volume minimization. It can be shipped after assembly, and the user can unpack and use it immediately after purchase, saving time, worry and effort. At the same time, because it can be folded, it is easy to store and does not take up space after use. It solves the problem of high freight caused by the large volume in the actual transportation process of the existing design.

[0040] As a preferred embodiment, as Figure 3 and Figure 4 shown, the main connecting frame 2 includes two columns 21, and on the side close to each other on the two columns 21, there are engaging columns 6 arranged facing each other. The engaging opening 41 is engaged with the engaging column 6. Preferably, the cross-section of the engaging column 6 is a trapezoidal structure. On the lower sides of the left and right sides of the pedal 4, there are engaging openings 41, and the shape of the engaging opening 41 is adapted to the engaging column 6, which is also a trapezoidal structure, so as to be easily engaged with the engaging column 6. The distance between the two columns 21 is greater than or equal to the width of the pedal 4, and the distance between the two engaging columns 6 is less than the width of the pedal 4, so that the pedal 4 can be firmly connected to the main connecting frame 2 through the engaging opening 41 and the engaging column 6.

[0041] Preferably, the support column 21 is a telescopic main body, which can be realized by a telescopic rod that can be extended and retracted up and down to adapt to the flush toilets of different heights.

[0042] As a preferred embodiment, as Figure 4 shown, limit pieces 42 are respectively arranged at positions corresponding to two clamping interfaces 41 on the lower side of the pedal 4. A through hole 421 is arranged on the limit piece 42. A limit block 61 is arranged on the clamping column. The clamping interface 41 and the limit piece 42 are respectively located on both sides of the limit block 61. The through hole 421 of the limit piece 42 is sleeved on the free end of the clamping column. Preferably, a connection hole 62 is arranged on the end surface of the free end of the clamping column, and the connection hole 62 can be connected with a connecting piece to limit the limit piece 42 on the clamping column.

[0043] The connection structure of the limit block 61 and the limit piece 42 in this embodiment can further enhance the stability of the connection of the pedal 4, making it safer and more reliable to use.

[0044] As a preferred embodiment, as Figure 2 shown, a rear accommodation groove 31 is arranged at the rear side of the rear connection frame 3. The pedal 4 can rotate backward and be embedded in the rear accommodation groove 31. The upper side surface of the pedal 4 is close to the bottom surface of the rear accommodation groove 31. Preferably, the rear connection frame 3 includes two rear side columns 32 and a rear connection plate 33. The rear connection plate 33 is connected between the two rear side columns 32. The rear side columns 32 and the rear connection plate 33 can be of an integral structure, making the rear connection frame 3 have stronger support strength.

[0045] In this embodiment, by arranging the rear accommodation groove 31 at the rear side of the rear connection frame 3, the pedal 4 can be folded relative to the rear connection frame 3 and embedded in the rear accommodation groove 31, so that the rear connection frame 3 is wrapped outside the pedal 4, thereby further reducing the occupied space after the folding toilet ladder is folded.

[0046] As a preferred embodiment, as Figure 2 and Figure 5 shown, the width of the rear connection frame 3 is less than or equal to the distance between the two support columns 21. The width of the rear connection frame 3 refers to its length in the left-right direction. As Figure 5 shown, the width of the rear connection frame 3 is less than or equal to the distance between the two support columns 21, so that after the pedal 4 is folded in the rear accommodation groove 31 of the rear connection frame 3, the rear connection frame 3 can be folded forward relative to the bottom connection frame 5, as Figure 6 shown, and the front side surface of the rear connection frame 3 is in relative contact with the upper side surface of the bottom connection frame 5.

[0047] As a preferred embodiment, as Figure 2As shown, the top end of the support column 21 extends backward to form a connecting portion 22, and the toilet seat 1 is rotatably connected to the rear ends of the two connecting portions 22. The connecting portion 22 enables the top end of the ladder frame to effectively extend towards the direction close to the toilet, making it more convenient to use.

[0048] As a preferred embodiment, as Figure 2 and Figure 7 shown, the length that the connecting portion 22 extends backward is greater than the thickness of the bottom connecting frame 5.

[0049] In this embodiment, by making the length that the connecting portion 22 extends backward greater than the thickness of the bottom connecting frame 5, as Figure 7 shown, the main connecting frame 2 can be folded backward relative to the bottom connecting frame 5, making the connecting portion 22 set downward. At this time, the toilet seat 1 can be rotated downward, and the toilet seat 1 can be rotated to the lower side of the bottom connecting frame 5, as Figure 8 shown, thereby realizing the minimum-volume folding of the folding toilet ladder. As a preferred embodiment, as Figure 1 shown, the bottom connecting frame 5 includes a bottom plate 52 and two bottom side columns 51. The bottom plate 52 is connected between the two bottom side columns 51 and the bottom plate 52 is arranged close to the front side of the bottom side columns 51. The bottom plate 52 can be used as the first-level pedal, and the pedal 4 is used as the second-level pedal to facilitate children's climbing. Preferably, in the state where the folding toilet ladder is unfolded and used, the front side of the bottom plate 52 extends to the front side of the pedal 4. Anti-slip pads or anti-slip patterns are provided on the bottom plate 52, and anti-slip pads or anti-slip patterns are provided on the pedal 4 to increase safety. Preferably, the bottom plate 52 and the two bottom side columns 51 are of an integral structure, having strong supporting strength.

[0050] As a preferred embodiment, as Figure 1 and Figure 6 shown, the length of the pedal 4 in the front-rear direction is less than the length of the bottom connecting frame 5 in the front-rear direction. The rear connecting frame 3 can be rotated to the upper side of the bottom connecting frame 5 and the front side surface of the rear connecting frame 3 is in relative contact with the upper side surface of the bottom connecting frame 5. The bottom surface of the pedal 4 is arranged upward. When the pedal 4, the rear connecting frame 3 and the bottom connecting frame 5 are folded relative to each other, the rear connecting frame 3 and the pedal 4 do not protrude from the front side of the bottom connecting frame 5.

[0051] As a preferred embodiment, as Figure 7 and Figure 8 shown, the length of the support column 21 is greater than the length of the bottom connecting frame 5 in the front-rear direction. The support column 21 can be folded backward relative to the bottom connecting frame 5, and the toilet seat 1 is rotated to the lower side of the bottom connecting frame 5, making the seat surface of the toilet seat 1 face downward.

[0052] The unfolded and used state of the folding toilet ladder in this embodiment is as Figures 1 - 3 shown.

[0053] The folding method of the folding toilet ladder in this embodiment is as follows Figures 5 - 8 shown. First, as Figure 5 shown, remove the pedal 4 from the clamping post 6 inside the main connecting frame 2 and rotate it backward, fold it relative to the rear connecting frame 3 and embed it into the rear receiving groove 61 of the rear connecting frame 3.

[0054] Then, as Figure 6 shown, rotate the rear connecting frame 3 forward relative to the bottom connecting frame 5 to fold it, so that the front side of the rear connecting frame 3 is in relative contact with the upper side of the bottom connecting frame 5.

[0055] As Figure 7 shown, then rotate the two struts 21 backward relative to the bottom connecting frame 5 to fold them, and the connecting part 22 connecting one end of the toilet seat 1 is arranged downward, so that the pedal 4 and the rear connecting frame 3 are located inside the main connecting frame and on the same parallel line, minimizing the volume.

[0056] As Figure 8 shown, then rotate the toilet seat 1 to the lower side of the bottom connecting frame 5, so that the seat surface of the toilet seat 1 faces downward, thereby completing the folding of the folding toilet ladder, reducing the occupied space and facilitating storage.

[0057] The above is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art of this technology can make several deformations and improvements without departing from the creative concept of the present invention, and all of them should be covered by the protection scope of the present invention.
