Description

TECHNICAL AREA

[0001] The present application relates to the technical field of children's reclining shells, in particular a foldable children's reclining shell. STATE OF THE ART

[0002] Existing infant car seats typically comprise an upper frame and a lower frame. For example, Chinese patent document CN218164724U discloses a rocking car seat in which support components and flexible textiles, such as covers, are connected between the upper and lower frames.

[0003] During disassembly, the support components must be removed to allow the upper and lower frames to fold. When folded, the upper and lower frames shift relative to each other, resulting in uneven stacking of the fabric cover and an increased length of the baby carrier, which complicates storage and packaging.

The term "and / or" used in this application includes any one or more and any combinations of the related elements listed therein.

[0032] In this application, the terms “first”, “second”, etc., are used for descriptive purposes only and are not intended to indicate or imply relative importance or to implicitly define the number or order of the specified technical features. Therefore, features defined as “first”, “second”, etc., may expressly or implicitly include one or more of these features. In the description of this application, “several” means at least two, for example, two, three, etc., unless expressly defined otherwise.

[0033] With reference to Fig. 1 to Fig. 3. The present application provides a child lying tray 1000 comprising two frames arranged opposite each other along the vertical direction, and a side frame 130 connected between the two frames. The two frames and the side frame form a receiving area for carrying an infant or toddler. The child lying tray 1000 further comprises a flexible fabric cover 140 (shown as a dashed line in the figures) connected between the two frames. The child lying tray 1000 can be mounted on a support frame to form a bedside crib or installed on a stroller, etc.

[0034] For clarity, the figures show only one side of the child's reclining shell 1000. The vertical direction runs along the Z-direction shown in the figures (also referred to as the vertical direction), the first direction is the X-direction shown in the figures (also referred to as the longitudinal direction), and the second direction, Y, runs perpendicular to the XZ-plane. Accordingly, "top," "bottom," "above," and "below" refer to the vertical direction. There are two sets of side frames 130 arranged side by side along the second direction, Y. Each set of side frames is arranged on a common reference plane (i.e., the XZ-plane), with the reference plane running parallel to the first direction.

[0035] The two frames comprise a first frame 110 and a second frame 120. The side frames 130 comprise two groups of elements, namely a first group 131 and a second group 132. The first group 131 comprises at least two rods, each rod of the first group 131 being slidably mounted on the first frame 110 and hinged at its other end to the second frame 120. All rods of the first group 131, together with the two frames, form a deformable structure with an unfolded state and a folded state. The unfolded state, in which the two frames move apart, is used to carry an infant or small child and can also be referred to as the operating state. In the folded state, the two frames lie close together. The second group 132 comprises at least one rod that is hinged to a rod of the first group 131 and to one of the frames.

[0036] Using the folding process as an example, the two frames are brought closer together using the rods of the first group. During this process, the movement of the two frames is limited by the action of the rods of the second group, ensuring that the two frames move along the vertical axis without any displacement. This means that the folded state has the same longitudinal dimensions as the unfolded state, which facilitates storage and packaging. Furthermore, the fabric cover is stacked more evenly and neatly when folded.

[0037] In one embodiment, as in Fig. As shown in Figure 1, when the child's reclining shell is in use, the first frame 110 is located on the underside and the second frame 120 on the top side. One end of each rod of the second group 132 is pivotally connected to a rod of the first group 131, and the other end is pivotally connected to the first frame 110. In another embodiment, the first frame 110 is located on the top side and the second frame 120 on the underside. One end of each rod of the second group 132 is pivotally connected to a rod of the first group 131, and the other end is pivotally connected to the second frame 120. For clarity, the following embodiments and figures are based on the structure of the first embodiment.

[0038] All the bars in the first group 131 are inclined in the same direction. "Inclined in the same direction" means that the direction in which each bar extends from its lower end to its upper end lies on the same side relative to the vertical. Preferably, for example, the bars in the first group 131 are parallel to each other.

[0039] The ends of all rods of the first group 131 that interact with the first frame 110 move synchronously in the same direction. In a preferred embodiment, the reclining shell further comprises a connecting seat 133, which is slidably mounted on the first frame 110. All rods of the first group 131 are pivotally connected to the connecting seat 133 and slide over it relative to the first frame 110. In the unfolded state, all rods of the first group 131 are arranged obliquely to the vertical direction, which allows the rods of the first group 131 to slide more quickly during unfolding and folding.

[0040] In one embodiment, the length of each rod of the second group 132 is less than or equal to half the length of each rod of the first group 131. Likewise, in the unfolded state, all rods of the second group 132 are arranged obliquely to the vertical direction, with each rod forming a triangular support structure with a rod of the first group. The direction of inclination of the rods of the second group 132 is opposite to that of the first group 131. In particular, both the first group 131 and the second group 132 are connected to the first frame 110. The first frame 110 is considered a plane, and the following angles α and β refer to the first frame 110. In the figures, the angle of inclination of all rods of the first group 131 is α and that of the second group 132 is β, where α < 90° and β > 90°. Preferably, α < 60° and β > 110°, for example α = 50° and β = 116°.

[0041] In one embodiment, the first group 131 comprises two or more support rods 151, wherein each pair of support rods 151 forms a deformable parallelogram structure with the two frames. This means that the second frame 120 runs parallel to the first frame 110, so that the two frames are as close as possible to each other when folded. The second group 132 comprises one or more stabilizing rods 161, wherein one end of each stabilizing rod 161 is pivotally connected to the first frame 110 and the other end is pivotally connected to the center of one of the support rods 151.

[0042] In the figures, the connecting seat 133 slides to one side in a first direction when folded. The first group 131 comprises two support rods 151, and the second group 132 comprises a stabilizing rod 161, which is arranged on the opposite side of the connected support rod 151. In the longitudinal direction, the articulated connection point of the stabilizing rod 161 with the first frame 110 is located near the end of the child's reclining shell 1000. During folding, the angle α gradually decreases, while the angle β increases.

[0043] In one embodiment, the end of a rod of the first group 131, which is articulated to the frame, is located longitudinally at the end of this frame. In another embodiment, the connecting seat 133, when folded, is located longitudinally near the end of the first frame.

[0044] In one embodiment, the articulated connection point of the stabilizing rod 161 with the support rod 151 deviates from the center 101 of the child's reclining shell 1000 along the first direction. The center 101 is the intersection of the vertical center line 102 and the horizontal center line 103 of the two frames.

[0045] With reference to Fig. 4 to Fig. Section 14 explains the specific structure of the connecting seat and the deformable structure with reference to the following embodiments and figures. The connecting seat 133 comprises several transverse connecting rods 1331 and longitudinal connecting rods 1332 that connect the respective transverse connecting rods 1331. The extension directions of the transverse connecting rods 1331 and the longitudinal connecting rods 1332 are the second direction and the first direction, respectively, and neither is limited to straight rods.

[0046] The two ends of the transverse connecting rods 1331 are each pivotally connected to the rods (symmetrically arranged support rods 151) of the first group of the two sets of side frames. In combination with the previous embodiments, there are two transverse connecting rods 1331 and two longitudinal connecting rods 1332, and they are arranged near the ends of the transverse connecting rods 1331 to increase the structural strength of the connecting seat 133 and thus prevent deformation, ensuring sliding stability. In the figures, the first frame 110 consists of hollow rods and has a first sliding groove and a second sliding groove. The support rod 151 projects partially into the first sliding groove, and the end of the transverse connecting rod 1331 projects into the second sliding groove and is pivotally connected to the support rod 151. The first frame 110 defines an interior space 134 in which the connecting seat 133 is located.The child lying shell 1000 further comprises a support plate 135 attached to the first frame 110 in the floor of the receiving area, the support plate 135 being firmly connected to the top of the first frame 110 and covering the connecting seat 133.

[0047] In one embodiment, the child's reclining shell further comprises a locking element that holds it in the unfolded position and a release element for unlocking the locking element. A locking mechanism can be located at any articulated position or between the connecting seat and the frame. For example, in Fig. 12 to Fig. 14 The locking element is a locking hook 210 rotatably attached to the first frame 110. The child's lying shell 1000 further comprises an elastic element (e.g., a spring) attached to the first frame 110, which acts on the locking hook 210. The locking hook 210 has a hook slot 211 that interacts with the cross-connecting rod 1331 and a chamfer 212 that adapts to the cross-connecting rod 1331. The unlocking element 230 is a wrench rotatably attached to the first frame 110, wherein the unlocking element 230 is arranged on one side of the first frame 110 in the first direction and is actuated via a transmission element 220 (e.g., a pull cord). Fig. 12) is connected to the locking hook 210. The specific unlocking and locking procedure is as follows: As in Fig. As shown in Figure 13, the release element 230 drives the locking hook 210 so that it rotates and compresses the elastic element. The locking hook 210 releases the locking mechanism of the cross-connecting rod 1331, and by pressing the second frame 120, the child's lying shell is folded. When locked, as shown in Fig. As shown in Figure 14, the connecting seat 133 moves until the cross-connecting rod 1331 abuts the inclined surface 212 and causes this locking hook 210 to rotate. As soon as the elastic element rebounds, it returns the locking hook 210 to its initial position to fix the cross-connecting rod 1331.

[0048] As in Fig.As shown in Figure 4, the child's reclining shell 1000 in one embodiment further comprises a drive element 240 that drives the connecting seat 133 to move it from the folded to the unfolded state. For example, the drive element 240 is a flexible band connected to the connecting seat 133. In combination with the previous embodiments, the flexible band is connected to a transverse connecting rod 1331. The flexible fabric cover 140 encloses the entire deformable structure, with the release element 230 and the drive element 240 being at least partially visible outside the flexible fabric cover 140.

[0049] In one embodiment, the child reclining tray 1000 comprises a handle 400, which is attached to the central section of the second frame 120. The handle 400 is rotatably connected to the central section of the second frame 120. Preferably, a flexible sunshade is attached between the handle 400 and the second frame 120. The child reclining tray 1000 also comprises an adapter 300, which is attached to the outer side of the central section of the first frame 110 or the second frame 120 for connection to an external support device (e.g., a support frame or a stroller frame). The aforementioned "central section" is not, strictly speaking, the exact center position, but rather an area near the center. Preferably, the adapter 300 is rotatable relative to the first frame 110 or the second frame 120 in order to adjust the angle of the child reclining tray on the support device.

[0050] In the child's reclining shell described in this application, the two frames move vertically towards each other in the vertical direction during folding, without shifting. This means that the folded state has the same longitudinal dimensions as the unfolded state, which facilitates storage and packaging. Furthermore, the fabric cover is stacked more evenly and neatly when folded.

[0051] The technical features of the aforementioned embodiments can be combined in any way desired. For clarity, not all possible combinations of the technical features in the aforementioned embodiments are described. However, as long as the combination of these technical features does not contradict each other, they are all considered to be disclosed in this description. If technical features of different embodiments are shown in the same figure, this figure can be considered a simultaneous disclosure of the combination examples of the respective embodiments.

[0052] The above-mentioned embodiments merely illustrate some embodiments of the present application. Their description is relatively concrete and detailed, but should not be interpreted as limiting the scope of protection of the patent application. It should be noted that a person skilled in the art can make several modifications and improvements without deviating from the invention concept of the present application, all of which fall within the scope of protection of the present application.
