Abstract
Description
Technical Field
[0001] This utility model relates to the field of bathtub technology, and more specifically to a folding bathtub. Background Technology
[0002] Traditional bathtubs are mostly made of rigid materials (such as ceramic, acrylic, or engineering plastics). Although structurally stable, they are bulky and non-deformable, making transportation, storage, and movement extremely inconvenient, especially for small apartments or outdoor use. In recent years, flexible bathtubs have gradually entered the market, using soft materials (such as rubber, PVC, or waterproof fabric) to replace the rigid structure, thus solving the portability problem of traditional bathtubs to some extent.
[0003] However, existing flexible bathtubs can only reduce their size by simply rolling or flattening them, which is cumbersome to operate. Furthermore, they still have an irregular shape after folding, making it impossible to achieve true flat storage and difficult to adapt to standard storage spaces. Utility Model Content

The peripheral side walls include two opposing first side walls and two opposing second side walls. The first side walls and / or the second side walls are provided with deformation creases. The bottom wall is provided with a fold crease in the middle. The peripheral side walls are folded through the deformation creases to form a semi-folded shape. The semi-folded shape and the bottom wall are folded downwards along the fold crease to form a fully folded shape.

[0030] First embodiment:
[0031] A type of folding bathtub, such as Figure 1 and Figure 3 As shown, the bathtub includes a flexible bottom wall 1 and peripheral side walls. Connecting creases 4 are provided at the joints between the peripheral side walls and the bottom wall 1, as well as at the joints between adjacent peripheral side walls. The peripheral side walls include two opposing first side walls 2 and two opposing second side walls 3. The peripheral side walls and the bottom wall 1 form a bathtub with an open top and a closed bottom. Deformation creases 6 are provided on the first side walls 2 and / or the second side walls 3. A fold 5 is provided in the middle of the bottom wall 1. The peripheral side walls are folded through the deformation creases 6 to form a semi-folded shape. The semi-folded shape and the bottom wall 1 are folded downwards along the fold 5 to form a fully folded shape.
[0032] The connecting crease 4, deformation crease 6, and bifold crease 5 are all flexible and bendable, allowing the bottom wall 1 and the peripheral sidewalls to be folded along the creases. The deformation creases 6 between the two first sidewalls 2 are symmetrical, and the deformation creases 6 between the two second sidewalls 3 are symmetrical (the deformation creases 6 on the two first sidewalls 2 are the same, and the deformation creases 6 on the two second sidewalls 3 are the same; the folding operation is also synchronous, which will not be described further below).
[0033] In this embodiment, the bottom wall 1 is rectangular. The fold 5 extends from one end to the other along the length of the bottom wall 1, allowing the bottom wall 1 to be folded into two identical halves through the fold 5. The first side wall 2 and the second side wall 3 are rectangular or slightly inclined trapezoidal shapes, wherein the first side wall 2 is located on the wide side of the bottom wall 1, and the second side wall 3 is located on the long side of the bottom wall 1, with the length of the second side wall 3 being greater than that of the first side wall 2.
[0034] In this embodiment, the deformation crease 6 includes a first crease 601 disposed in the middle of the first sidewall 2. The first crease 601 extends vertically from the bottom to the top of the first sidewall 2. It also includes a second crease 602 symmetrically disposed at both ends of the first sidewall 2. The second crease 602 extends obliquely upward from the bottom of one end of the first sidewall 2 to the middle of the top. The second crease 602 and the first crease 601 intersect at the middle of the top of the first sidewall 2.
[0035] When folding the bathtub in this embodiment: first, fold the second crease 602 inward, so that both first sidewalls 2 and both second sidewalls 3 are folded inward to a horizontal state. The first sidewall 2 deforms after folding while the second sidewall 3 remains intact. The second sidewall 3 covers the first sidewall 2, forming a semi-folded shape. Then, fold the perimeter wall and bottom wall 1 of the semi-folded shape together. The first crease 601 and the fold line 5 are located on the same vertical plane. The semi-folded shape is folded downward through the first crease 601, and the bottom wall 1 is folded downward through the fold line 5, so that the bathtub is folded into a sheet-like fully folded shape.
[0036] Second embodiment:
[0037] A type of folding bathtub, such as Figure 4 and Figure 5 As shown, the difference between this embodiment and the first embodiment is that the deformation crease 6 includes a first crease 601 disposed in the middle of the first sidewall 2, the first crease 601 extending vertically from the bottom to the top of the first sidewall 2, and also includes a second crease 602 symmetrically disposed at both ends of the second sidewall 3, the second crease 602 extending obliquely upward from the bottom of one end of the second sidewall 3 toward the middle to the top.
[0038] When folding the bathtub in this embodiment: first, fold the second crease 602 inward, so that both first sidewalls 2 and both second sidewalls 3 are folded inward to a horizontal state. The second sidewall 3 deforms after folding while the first sidewall 2 remains intact. The first sidewall 2 covers the second sidewall 3, forming a semi-folded shape. Then, fold the peripheral sidewalls and bottom wall 1 of the semi-folded shape together. The semi-folded shape is folded downward through the first crease 601, and the bottom wall 1 is folded downward through the crease 5, so that the bathtub is folded into a sheet-like fully folded shape.
[0039] Third embodiment:
[0040] A type of folding bathtub, such as Figure 6 and Figure 7 As shown, the difference between this embodiment and the first embodiment is that the deformation crease 6 includes a first crease 601 disposed in the middle of the first sidewall 2, which extends vertically from the bottom to the top of the first sidewall 2. It also includes second creases 602 symmetrically disposed at both ends of the first sidewall 2, which extend obliquely upwards from the bottom of one end of the first sidewall 2 to connect with the first crease 601 and form an intersection point located below the middle of the top of the first sidewall 2. The first crease 601 includes an upper part 6011 and a lower part 6012 located above and below the intersection point.
[0041] When folding the bathtub in this embodiment: first, fold the second crease 602 and the upper part 6011 together inward, so that the two second side walls 3 are folded inward until they fit together at the top. The second side walls 3 remain intact after folding. The triangular part of the first side wall 2 located at the bottom edge and the two second creases 602 remains intact after folding, while the upper part is deformed to form a semi-folded shape. Then, fold the peripheral side wall of the semi-folded shape together with the bottom wall 1. The semi-folded shape is folded downward through the lower part 6012 of the first crease 601, and the bottom wall 1 is folded downward through the fold 5, so that the bathtub is folded into a sheet-like fully folded shape.
[0042] Fourth embodiment:
[0043] A type of folding bathtub, such as Figure 8 and Figure 9 As shown, the difference between this embodiment and the first embodiment is that the deformation crease 6 includes a first crease 601 disposed in the middle of the first sidewall 2, the first crease 601 extending vertically from the bottom to the top of the first sidewall 2. It also includes second creases 602 symmetrically disposed at both ends of the first sidewall 2, the second creases 602 extending obliquely upward from the bottom of one end of the first sidewall 2 to connect with the first crease 601 and form an intersection point. The intersection point is located below the middle of the top of the first sidewall 2. Furthermore, it includes a third crease 603 horizontally disposed around the perimeter of the sidewall, the third crease 603 connected to the intersection point, and the third crease 603 and the intersection point are at the same height. The first crease 601 includes an upper part 6011 and a lower part 6012 located above and below the intersection point.
[0044] When folding the bathtub in this embodiment: First, fold the second crease 602, the upper part 6011, and the third crease 603 together inward, so that the two first side walls 2 and the two second side walls 3 are folded inward. The parts of the first side walls 2 and the second side walls 3 below the third crease 603 are in a horizontal state, and the parts above the third crease 603 are in a vertical state, forming a half-folded shape. Then, fold the peripheral side walls and the bottom wall 1 of the half-folded shape together. The half-folded shape is folded downward through the lower part 6012 of the first crease 601, and the bottom wall 1 is folded downward through the crease 5, so that the bathtub is folded into a sheet-like fully folded shape.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
