Description

Technical Field

[0001] The utility model relates to a folding bathtub for infants and young children, in particular to a folding bathtub with a sliding support structure. The sliding support structure is arranged on the basin edge of the bathtub to support and maintain the folding bathtub in an unfolded state. Background Art

[0002] A foldable infant bathtub is a bathtub specially designed for bathing infants. For example, the utility model patent with authorization announcement number CN219249993U discloses a bathtub in which a basin body and supporting legs can be synchronously extended and retracted, including a basin body that can be unfolded or folded in the height direction, and supporting legs on both sides of the basin body; the basin body includes a hard basin edge and a basin bottom, and a basin peripheral wall between the basin edge and the basin bottom; the basin peripheral wall is provided with a flexible first folding layer, a hard isolation layer and a flexible second folding layer from top to bottom; the first folding layer and the second folding layer can be independently folded or unfolded in the height direction; the upper ends of the supporting legs are connected to the basin edge and can be extended or shortened in the height direction.

[0003] Usually the hard part of a bathtub is made of PP, and the foldable flexible part is made of TPE. At least the edge and bottom of the basin must be made of hard plastic. When the bathtub is in an expanded shape, it can provide support to maintain its expanded shape and prevent partial collapse of the bathtub from affecting water storage and bathing.

[0004] The bathtub disclosed in the aforementioned patent document also has a storage state, that is, all the folding layers are folded, the entire bathtub body is compressed into a flat state, and the two supporting legs are folded and leaned against the back side of the bathtub edge for easy storage. However, in this case, although the bathtub is compressed in the height direction, it still has a large flattened area, which still causes inconvenience in packaging, transportation and storage.

[0005] The utility model patent with authorization announcement number CN217039897U discloses a folding bathtub, including a basin body; and a support ring, the support ring including: a left ring portion and a right ring portion, both of which are respectively arranged on both sides of the upper end of the basin body; and an upper folding portion, which is arranged between the left ring portion and the right ring portion; wherein the upper folding portion is made of soft material, and the support ring realizes rotational folding between the left ring portion and the right ring portion through deformation of the upper folding portion, and at the same time, the folding of the support ring drives the deformation and folding of the basin body.

[0006] The folding bathtub disclosed in the patent document is further folded left and right based on the compression in the height direction, so that the horizontal area of ​​the bathtub after folding and storage is reduced by half, which is more convenient for packaging, transportation and storage.

[0007] However, in order to ensure that it can maintain the unfolded shape after unfolding, the patent requires an independent stopper to be provided on the lower surface of the upper folding part, and the two ends of the stopper extend to the left ring part and the right ring part respectively, so as to limit the downward rotation of the left ring part and the right ring part after unfolding. The stopper is removed when storing, and the folding bathtub is packed and stored separately, which not only takes up extra packaging and storage space, but also is easy to be lost during transportation and multiple uses. Once lost, the folding bathtub cannot maintain the unfolded shape, and its use function is completely lost. Utility Model Content

When the foldable basin body 10 has more than two foldable layers 14, the support legs 20 can also be synchronously telescoped to adjust the length according to the different heights of the foldable basin body 10.

[0101] like Figure 1 , Figure 2 Recombination Figure 3 As shown, the foldable basin body 10 provided in this embodiment can be further folded in half to form a folded storage state based on the flat storage state. Specifically, the basin edge 11 includes a first hard edge 11a, a second hard edge 11b, and two first flexible portions 11c located between the first hard edge 11a and the second hard edge 11b. It should be understood that since the basin edge 11 is annular, there are two first flexible portions 11c between the first hard edge 11a and the second hard edge 11b, one on the front side and one on the rear side.

[0102] The basin bottom 13 includes a first hard bottom 13a, a second hard bottom 13b, and a second flexible portion 13c located between the first hard bottom 13a and the second hard bottom 13b. The foldable basin body 10 is divided into a first basin body 10a and a second basin body 10b by the first flexible portion 11c and the second flexible portion 13c. When the foldable basin body 10 is in a flat storage configuration, the first flexible portion 11c and the second flexible portion 13c are deformed to fold the first basin body 10a and the second basin body 10b relative to each other, so that the foldable basin body 10 is in a folded storage configuration.

[0103] It should be understood that, in order to support the formation of the folded storage form, not only the first flexible portion 11c and the second flexible portion 13c between the first basin body 10a and the second basin body 10b are flexible, but also the portion of the basin peripheral side wall 12 located on the fold crease with the first flexible portion 11c and the second flexible portion 13c needs to be flexible. For other embodiments with more than two foldable layers 14, the portion of the hard layer between two adjacent foldable layers 14 located on the fold crease should also be set to be partially flexible to support the formation of the folded storage form.

[0104] Therefore, when the foldable basin body 10 is in the unfolded form, the parts located on the folded crease are all made of flexible material, which will cause the foldable basin body 10 to collapse and deform and be unable to maintain the unfolded form. Especially when water is added to the inside of the foldable basin body 10, or an infant enters the basin and the basin body is subjected to gravity, the foldable basin body 10 will collapse, posing a safety risk.

[0105] For this reason, Figures 2 to 7 As shown, the folding bathtub 100 with a sliding support structure also includes two sliding support structures 30 arranged on the edge of the basin, and each sliding support structure 30 includes a first support arm 31, a second support arm 32 and a sliding member 33. The first support arm 31 is connected to the first hard edge 11a, and the second support arm 32 is connected to the second hard edge 11b on the same side. The sliding member 33 is connected to the first support arm 31 and can slide along the first support arm 31.

[0106] It should be noted that in other embodiments, the first support arm 31 may be connected to the second hard edge 11b, and the second support arm 32 may be connected to the first hard edge 11a on the same side. In addition, the installation directions of the front and rear sliding support structures 30 may be consistent or opposite. Of course, this embodiment adopts a consistent design, and the user can slide in the same direction when operating the front and rear sliding members 33, which is more in line with operating habits.

[0107] When the sliding member 33 slides to Figure 4 and Figure 5 In the first position v1 shown in FIG. 1 , the first support arm 31 is separated from the second support arm 33 so that the foldable basin body 10 is switched to the folded storage state. Figure 6 and Figure 7In the second position v2 shown in FIG. 1 , the sliding member 33 is connected to the first support arm 31 and the second support arm 32 at the same time, and the sliding support structure 30 spans the first flexible portion 11c on the same side, and the first flexible portion 11c on the same side is reinforced and supported by the hard sliding support structure 30. When the sliding support structures 30 on both the front and rear sides slide the sliding member 33 to the second position v2 shown in FIG. *, the basin edge 11 is supported and maintained in the unfolded state of the basin edge 11. When the basin edge 11 is maintained in the unfolded state, the entire unfolded foldable basin body 10 is supported and maintained in the unfolded state, and will not collapse, and can store water normally and be used for bathing infants and young children.

[0108] It can be seen that the folding bathtub 100 with a sliding support structure provided by the utility model has at least the following three technical effects: First, by arranging a sliding support structure 30 between the first hard edge 11a and the second hard edge 11b of the basin edge 11, the first flexible portion 11c of the basin edge 11 is reinforced and supported, so that the basin edge 11 and even the foldable basin body 10 are supported and maintained in the expanded state.

[0109] Second, the sliding support structure 30 is connected to the first hard edge 11a and the second hard edge 11b with its first support arm 31 and the second support arm 32 respectively. The sliding support structure 30 is installed on the basin edge 11. Compared with the limiting parts independent of the basin body in the prior art, it overcomes the problems of needing to be packaged and stored separately and easy to lose, and realizes the integrated packaging, transportation and storage of the sliding support structure 30 and the foldable basin body 10.

[0110] Third, by sliding the sliding member 33, the first support arm 31 and the second support arm 32 are controlled to be separated or connected as a whole spanning the first flexible portion 11c. This is not only convenient and quick to operate, but also achieves the effect of no assembly and quick molding, compared with the prior art in which an independent limiting member needs to be installed on the edge of the basin, which causes inconvenience and easy displacement in positioning.

[0111] like Figure 5 , Figure 7 and Figure 8 As shown, the sliding member 33 is slidably mounted on the first support arm 31. Of course, in other embodiments, the sliding member 33 may be half-covered on the first support arm 31, and slide grooves may be provided on both sides of the first support arm 31 and the second support arm 32, and plugs inserted into the slide grooves may be provided on both sides of the sliding member 33; or the slide grooves may be provided on the outer sides of the first support arm 31 and the second support arm 32, and the sliding member 33 may be provided as a sliding block embedded in the slide grooves, etc.

[0112] The first support arm 31 includes a first limiting portion 31a and a first sleeve portion 31b, the sliding member 33 is slidably sleeved on the outer periphery of the first sleeve portion 31b, and the size of the first limiting portion 31a is larger than the inner diameter of the sliding member 33. The second support arm 32 includes a second limiting portion 32a and a second sleeve portion 32b, the length of the second sleeve portion 32b is smaller than the length of the sliding member 33, and the size of the second limiting portion 32a is larger than the inner diameter of the sliding member 33.

[0113] When the sliding member 33 slides to the first position v1, the sliding member 33 is located at the first sleeve portion 31b, so that the first support arm 31 and the second support arm 32 are separated, and the first limit portion 31a is used to limit the sliding member 33 from sliding further away from the second support arm 32. When the sliding member 33 slides to the second position v2, the first connection portion 33a of the sliding member 33 is connected to the first sleeve portion 31b, and the second connection portion 33b of the sliding member 33 is connected to the second sleeve portion 32b, so that the sliding member 33 is connected to the first support arm 31 and the second support arm 32 at the same time, so that the sliding support structure 30 forms a whole across the first flexible portion 11c, and the second limit portion 32a is used to limit the sliding member 33 from sliding further away from the first support arm 31.

[0114] It can be seen that in this embodiment, the sliding member 33 is slidably mounted on the first support arm 31, which not only makes the sliding operation more convenient, but also the sleeve-jointed structure can enhance the structural strength of the sliding support structure 30 when forming a supporting whole, making its supporting effect more stable and reliable.

[0115] like Figure 5 , Figure 7 and Figure 8 As shown, the sliding member 33 includes a first connecting portion 33a and a second connecting portion 33b. When the sliding member 33 slides to the second position v2, the first connecting portion 33a is connected to the first support arm 31, and the second connecting portion 33b is connected to the second support arm 32. A first window c1 is formed on the first connecting portion 33a, and a second window c2 is formed on the second connecting portion 33b. A telescopic positioning member 40 is provided on the first support arm 31, and the telescopic positioning member 40 is elastically provided on the first support arm 31.

[0116] When the sliding member 33 slides to the first position v1, the telescopic positioning member 40 extends from the second window c2 to position the sliding member 33 at the first position v1, and the sliding member 33 is not easy to fall off from the first support arm 31. When the sliding member 33 slides to the second position v2, the telescopic positioning member 40 extends from the first window c1 to position the sliding member 33 at the second position v2, so as to avoid the sliding member 33 accidentally moving when using the bathtub and causing the first support arm 31 to separate from the second support arm 32.

[0117] It can be seen that in this embodiment, the size of the sliding member 33, the position of the first window c1, the second window c2 and the telescopic positioning member 40, and the length of the first limiting portion 31a, the first sleeve portion 31b and the second limiting portion 32a, the second sleeve portion 32b cooperate with each other and support each other in terms of function, so as to form an overall design scheme with superimposed effects. When the sliding member 33 slides to the first position v1, the telescopic positioning member 40 just extends out of the second window c2, and the sliding member 33 just abuts against the first limiting portion 31a; when the sliding member 33 slides to the second position v2, the telescopic positioning member 40 just extends out of the first window c1, and the sliding member 33 just abuts against the second limiting portion 31b. The coordination relationship formed between the multiple components makes it more convenient for users to operate, and the user experience is greatly improved in one step.

[0118] Preferably, if Figure 8 As shown, the telescopic positioning member 40 is elastically arranged on the first support arm 31 through a spring s. An installation cavity 41 is arranged in the first support arm 31, and a spring positioning column 42 and a plurality of telescopic positioning columns 43 are arranged in the installation cavity 41. In this embodiment, there are four telescopic positioning columns 43. The spring s is sleeved on the spring positioning column 42 to limit the spring s to expand and contract in its height direction to prevent it from deflecting and bending.

[0119] The telescopic positioning member 40 is provided with a plurality of positioning notches 44, and in this embodiment, there are four corresponding notches. The telescopic positioning member 40 is placed in the mounting cavity 41, and the positioning notches 44 are clamped on the telescopic positioning column 43. The telescopic positioning member 40 extends out from the first window c1 or the second window c2 under the elastic action of the spring s. When the sliding member 33 slides, the spring s is compressed by squeezing the telescopic positioning member 40. The positioning notches 44 cooperate with the telescopic positioning column 43 to stabilize the telescopic movement of the telescopic positioning member 40. The mounting cavity 41 is closed by a mounting plate 45, and a third window c3 is opened on the mounting plate 45 for the telescopic positioning member 40 to be telescoped.

[0120] Of course, in other embodiments, the telescopic positioning member 40 can also be elastically arranged on the first support arm 31 in other ways. Typically, the spring s is replaced with other elastic members, or the telescopic positioning member 40 itself is arranged as an elastic sheet, an elastic buckle structure, etc. The telescopic positioning member 40 elastically arranged with the spring s is more smooth in telescoping and the forces on both sides are more balanced.

[0121] like Figures 2 to 7 As shown, the cross-section of the basin edge 11 is arc-shaped, and its back side is recessed to form a basin edge groove 15. The sliding support structure 30 is arranged in the basin edge groove 15 on the back side of the basin edge 11, thereby preventing infants and young children from accidentally touching and getting injured during bathing, or accidentally separating the first support arm 31 from the second support arm 32.

[0122] The first support arm 31 of the sliding support structure 30 is rotatably hinged at the end of the first rigid edge 11a, and the second support arm 32 is rotatably hinged at the end of the second rigid edge 11b on the same side. In other embodiments, the first support arm 31 of the sliding support structure 30 may be rotatably hinged at the end of the second rigid edge 11b, and the second support arm 32 may be rotatably hinged at the end of the first rigid edge 11a on the same side. When the first support arm 31 is separated from the second support arm 32, the first support arm 31 and the second support arm 32 may be rotated relative to the first rigid edge 11a and the second rigid edge 11b, respectively, so as to be conveniently stored together with the foldable basin body 10 in a folded storage form.

[0123] like Figure 5 , Figure 7 and Figure 8 As shown, the sliding member 33 is provided with an arc-shaped protrusion piece p for facilitating the sliding operation thereof. In this embodiment, the arc-shaped protrusion piece p is arranged between the first connecting portion 33a and the second connecting portion 33b, which is more in line with the user's operating habits.
