CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a National Stage application of PCT/EP2023/053921, filed on Feb. 16, 2023, which claims the benefit of Chinese Application No. 202210140894.9, filed on Feb. 16, 2022 and Chinese Application No. 202211346936.0, filed on Oct. 31, 2022, all of which are incorporated herein by reference in their entirety.
TECHNICAL FIELD
The present disclosure relates to the technical field of buckles, in particular to a buckle assembly with adjustable position and a baby carrier including the buckle assembly.
BACKGROUND
A baby carrier, such as a baby carriage, is a tool for carrying babies (including infants, toddlers, children, etc.). The baby carriage usually has wheels and a seat. The seat may include a cushion and a backrest. The cushion is used to bear legs and hips of a baby, and the backrest is used to support the back and head of the baby. The wheels can enable the baby carriage to be conveniently pushed. The seat is usually provided with a safety belt to restrain the baby when the baby carriage is pushed, thereby ensuring his/her safety. The safety belt may include a shoulder belt, a waist belt, an abdominal belt, and the like to restrain different parts of the baby's body.
The baby carriage in the prior art may have an adjustable shoulder belt. An upper end of the shoulder belt may be connected to an adjusting buckle which is slidably arranged on an adjusting belt. Both ends of the adjusting belt are connected to the backrest. As the adjusting buckle may slide on the adjusting belt, a position of the upper end of the shoulder belt is adjustable to adapt to babies of different sizes. The backrest of the baby carriage is usually provided with a back cushion, so as to provide a softer touch. The back cushion may be provided with a slit to allow one end of the shoulder belt and the adjusting buckle to pass through.
However, in the prior art, when the shoulder belt passes through the slit, it tends to spread the slit, so that the slit becomes unsightly in appearance, and even the backrest may be partially exposed, resulting in bad touch at the slit. After a small cushion is installed, the shoulder belt is difficult to fit the small cushion, which makes the appearance of the baby carriage messy. Moreover, the shoulder belt of the existing baby carriage is very inconvenient to use, for example, the shoulder belt needs to be removed together with the buckle. This operation is inconvenient, and the height adjustment of the shoulder belt cannot be quickly realized.
SUMMARY
The present disclosure provides a buckle assembly including a sliding element and a guiding element, wherein the sliding element includes a first fitting part and the guiding element includes a second fitting part, and wherein one of the first fitting part and the second fitting part receives the other, so that the sliding element is connected to the guiding element and may slide linearly on the guiding element.
The present disclosure provides a baby carrier including a frame; a backrest connected to the frame; a back cushion having a slit and at least partially covering the backrest; a belt having an end attached to the frame; and the buckle assembly as described above, wherein the buckle assembly connects the other end of the belt to the backrest. The buckle assembly passes through the slit of the back cushion, and connects the other end of the belt to the backrest to adjust a height of the other end of the belt.
The present disclosure provides a sliding element. The sliding element includes a first fitting part, and the first fitting part further includes a connecting buckle and a neck, wherein the neck connects the connecting buckle to the first fitting part, and a width of the neck is smaller than a width of either of the connecting buckle and the first fitting part.

Referring to FIGS. 1 and 9-11, the buckle assembly may include a sliding element 10 and a guiding element 20. The sliding element 10 may include a first fitting part 130. The guiding element 20 may include a second fitting part 210. One of the first fitting part 130 and the second fitting part 210 may be formed as a tubular element, while the other of the first fitting part 130 and the second fitting part 210 may be formed as an annular element. In the first embodiment, the first fitting part 130 may be formed as an annular element, while the second fitting part 210 may be formed as a tubular element. As shown in FIG. 2, the first fitting part 130 formed as an annular element may have a substantially C-shaped cross-section and may be formed with an opening 131. The annular element may have a large width so that it is formed in a shape of a sleeve. The annular element may also have a smaller width, so that it is formed into a C-shaped ring. The tubular element may have a generally cylindrical shape, and may be solid or hollow. An inner shape of the first fitting part 130 formed as an annular element may correspond to an outer shape of the second fitting part 210 formed as a tubular element, thereby forming a snap fit. That is, the second fitting part 210 may be accommodated in the first fitting part 130 to form connection between the sliding element 10 and the guiding element 20. Optionally, the tubular element may be formed with an outer contour of other shapes, such as a regular hexagon, so that the first fitting part 130 can be prevented from pivoting with respect to the second fitting part 210 to some extent.
Referring to FIGS. 1 and 8, the first fitting part 130 formed as an annular element may receive the second fitting part 210 formed as a tubular element, so that the sliding element 10 is connected to the guiding element 20 and the sliding element 10 may slide linearly on the guiding element 20.
Referring to FIGS. 1-7, the sliding element 10 may further include a connecting buckle 110 and a neck 120. The neck 120 may connect the connecting buckle 110 with the first fitting part 130. The sliding element 10 may be integrally formed. A width of the neck 120 may be smaller than a width of any one of the connecting buckle 110 and the first fitting part 130. The above width may refer to a dimension in a left-right direction as shown in FIG. 2.
Referring to FIG. 8, the guiding element 20 may further include a connecting part 230. A width of the connecting part 230 may be smaller than a width of the second fitting part 210. The above width may refer to a dimension in the left-right direction as shown in FIG. 8.
Referring to FIG. 9, the baby carrier of the present disclosure may include a backrest 80. The backrest 80 shown in FIG. 9 is rectangular, but the present disclosure is not limited thereto. The guiding element 20 may be formed in an elongated shape. Two guiding elements 20 may be symmetrically provided to the backrest 80 (for example, by sewing, adhering, etc.). The guiding element 20 may be arranged substantially vertically or slightly obliquely. The connecting buckle 110 of the sliding element 10 may be slidably connected to the belt 30. The belt 30 may be a shoulder belt of the baby carrier for restraining a shoulder of an occupant, thereby protecting the safety of the occupant. The belt 30 may be a woven belt. The buckle assembly may further include an adjusting buckle 40. The connecting buckle 110 may include a through hole 111. One end of the belt 30 may pass through the adjusting buckle 40, then through the through hole 111, and finally through the adjusting buckle 40 again. The adjusting buckle 40 may exert a certain clamping force on the belt 30 passing therethrough, thereby maintaining a distance of the belt 30 located between the adjusting buckle 40 and the guiding element 20. In other words, the adjusting buckle 40 may be used to adjust a position of the belt 30 passing through the through hole, and therefore, the adjusting buckle 40 may be used to adjust the tightness of the belt 30 with respect to a baby carried on the baby carrier. The adjusting buckle 40 may be, for example, a common “![custom-character]()
”-shaped (two-hole shaped) or “![custom-character]()
”-shaped (three-hole shaped) buckle. The other end of the belt 30 may be connected to a frame or cushion of the baby carrier. In this way, one end of the belt 30 may move on the backrest 80 through the buckle assembly, while the other end of the belt 30 is fixedly connected to the baby carrier, so that the belt 30 can be adapted to babies or children with different shoulder heights.
Although only one adjusting buckle 40 and one belt 30 are shown in FIG. 9, it is only intended to better show the sliding element 10. In actual use, the sliding element 10 at a right side is also connected to a belt 30 and an adjusting buckle 40.
Referring to FIG. 10, the baby carrier includes a back cushion 90 provided at a side of the backrest 80. The back cushion 90 shown in FIG. 10 is rectangular, but the present disclosure is not limited thereto. The back cushion 90 may have a size that completely covers the backrest 80 and may have a shape corresponding to the backrest 80. The back cushion 90 may be located between the back of the occupant and the backrest 80. The back cushion 90 may be flexible to provide a comfortable feeling. A slit 910 may be formed on the back cushion 90. The number of slits 910 may correspond to the number of buckle assemblies, for example, two, but the present disclosure is not limited thereto. In this embodiment, two slits 910 are symmetrically arranged on the backrest 90. The slit 910 may be elongated and may extend in a direction substantially consistent with the guiding element 20. A length of the slit 91 may be equal to or less than a length of the guiding element 20. The slit 910 shown in FIG. 10 may have a certain width, and alternatively, parts of the slit 910 on both sides may overlap with each other, so that objects behind the slit 910 cannot be seen visually, thereby improving the aesthetics of the baby carrier.
Referring to FIG. 11, the neck 120 of the sliding element 10 may pass through the slit 910, so that the connecting buckle 110 is located below the backrest 90 (according to a perspective shown in FIG. 11), and the first fitting part 130 is located above the backrest 90 (according to a perspective shown in FIG. 11). Since the neck 120 is thinner than the connecting buckle 110 and the first fitting part 130, the slit 910 will not be greatly deformed due to the neck 120 penetrating therethrough. In this way, the appearance of the back cushion 90 at the slit 910 can be kept beautiful. The connecting buckle 110 may be formed as a rectangular sheet. The connecting buckle 110 may cover a position where the neck 120 passes through the slit 910. Therefore, even if the slit 910 is slightly deformed by the neck 120 penetrating therethrough, the deformed part will be covered by the connecting buckle 110 without affecting the appearance of the baby carrier. A thickness of the connecting buckle 110 may be formed to facilitate grasping and moving by fingers.
Referring to FIG. 11, an opening 131 may be formed at a side of the first fitting part 130 away from the neck 120. A size of the opening 131 may correspond to a size of the connecting part 230. An inner space of the first fitting part 130 may match with an outer contour of the second fitting part 210. In this way, the sliding element 10 may smoothly slide on the guiding element 20. The size of the opening 131 is less than that of the second fitting part 210, so that the first fitting part 130 and the second fitting part 210 will not be disengaged from each other.
A second embodiment of the present disclosure will be described below.
FIG. 12 is a perspective view of a sliding element of a buckle assembly according to a second embodiment of the present disclosure, FIG. 13 is a top view of the sliding element of the buckle assembly according to the second embodiment of the present disclosure, FIG. 14 is a side view of the sliding element of the buckle assembly according to the second embodiment of the present disclosure, and FIG. 15 is a front view of the sliding element of the buckle assembly according to the second embodiment of the present disclosure.
Referring to FIGS. 12-15, the second embodiment of the present disclosure is mainly different from the first embodiment in that, the connecting buckle 110 further includes a locking part 112. The locking part 112 may be a rod provided in the through hole 111. The belt 30 passes through the through hole 111 in a first direction from one side of the locking part 112, and passes through the through hole 111 again in a second direction opposite to the first direction from the other side of the locking part 112. In other words, with the locking part 112, the connecting buckle 110 may simultaneously have a function of the adjusting buckle 40. In this way, the buckle assembly of the second embodiment of the present disclosure may not include the adjusting buckle 40.
The locking part 112 may be alternately formed with a plurality of protrusions and a plurality of depressions. In other words, the locking part 112 may be formed in an uneven shape to increase a friction force. It can be understood that other ways can also be used to increase the friction force, such as bumps and stripes, or other materials with higher friction force (for example, rubber) can be used to form the locking portion 112.
The connecting buckle 110 further includes an operating part 114. The operation part 114 may be formed as a lug protruding from one side (for example, a lower side in FIGS. 12, 15 and 24) of the connection buckle 110. The operating part 114 may be grasped by the user's fingers to move the sliding element conveniently.
A third embodiment of the present disclosure will be described below.
FIG. 16 is a perspective view of a sliding element of a buckle assembly according to a third embodiment of the present disclosure, FIG. 17 is a top view of the sliding element of the buckle assembly according to the third embodiment of the present disclosure, FIG. 18 is a side view of the sliding element of the buckle assembly according to the third embodiment of the present disclosure, FIG. 19 is a front view of the sliding element of the buckle assembly according to the third embodiment of the present disclosure, FIG. 20 is a rear view of the sliding element of the buckle assembly according to the third embodiment of the present disclosure, FIG. 24 is an exploded perspective view of the sliding element of the buckle assembly according to the third embodiment of the present disclosure, and FIG. 25 is a schematic perspective view of the sliding element of the buckle assembly according to the third embodiment of the present disclosure.
Referring to FIGS. 16-20 and 24-25, the third embodiment of the present disclosure is different from the second embodiment in that, a pivot shaft 121 may be formed on the neck 120 of the sliding element 10. A pivot hole 113 may be formed on the connecting buckle 110. The pivot shaft 121 may be positioned in the pivot hole 113 so that the connecting buckle 110 may pivot with respect to the neck 120. Since the connecting buckle 110 may pivot with respect to the neck 120, it can be operated more conveniently, for example, the connecting buckle 110 may be rotated to an appropriate angle (as shown in FIG. 25), and the operator may pinch/hold a lower part of the connecting buckle 110 with his thumb and forefinger to move the sliding element 10 or adjust the belt 30 more conveniently. Furthermore, since the connecting buckle 110 may pivot with respect to the neck 120, the connecting buckle 110 can better adapt to the movement of the belt 30. As shown in FIG. 25, the connecting buckle 110 may pivot in an arrow direction with respect to the neck 120.
A fourth embodiment of the present disclosure will be described below.
FIG. 21 is a schematic view of a buckle assembly according to a fourth embodiment of the present disclosure.
Referring to FIG. 21, the fourth embodiment of the present disclosure is different from the first embodiment in that, the guiding element 20 may further include a wing 220. The wing 220 may be formed on a side of the connecting part 230 opposite to the second fitting part 210, and the wing 220 may be formed as a sheet perpendicular to the connecting part 230. That is, as shown in FIG. 21, the wing 220 is formed as a horizontal sheet. The connecting part 230 extends upward perpendicular to the wing 220. The second fitting part 210 is located at an upper end of the connecting part 230. The wing 220 may be formed as a square, a rectangle or a circle, for example, but the shape of the wing 220 is not limited in the present disclosure. The wing 220 may keep the second fitting part 210 in an upright state more stably, so that the second fitting part 210 is not easily moved by an external force to skew and contact with the backrest 80, thereby prevent from affecting the connection between the second fitting part 210 and the first fitting part 130.
A fifth embodiment of the present disclosure will be described below.
FIG. 22 is a schematic view of a buckle assembly according to a fifth embodiment of the present disclosure.

The two first fitting parts 130 may be connected to the two second fitting parts 210, respectively. The wing 220 may connect two connecting parts 230. In this embodiment, since there are more connecting positions between the sliding element 10 and the guiding element 20 than in other embodiments, the connection between the sliding element 10 and the guiding element 20 is more stable. Optionally, the sliding element 10 may include more than two first fitting parts 130 and more than two necks 120, and the guiding element 20 may include more than two second fitting parts 210 and more than two connecting parts 230.
A sixth embodiment of the present disclosure will be described below.
FIG. 23 is a schematic view of a buckle assembly according to a sixth embodiment of the present disclosure.
Referring to FIG. 23, the sixth embodiment of the present disclosure is different from the fourth embodiment in that, the first fitting part 130 may be formed as a tubular element, while the second fitting part 210 may be formed as an annular element. The second fitting part 210 formed as an annular element may be formed with an opening at the upper side, and the wing 220 extends horizontally from both sides of the opening to left and right sides thereof. That is, the guiding element 20 may have only the second fitting part 210 and the wing 220, and may not have the connecting part 230. The first fitting part 130 formed as a tubular element is formed at a lower end of the neck 120. The first fitting part 130 is received by the second fitting part 210, thereby forming the connection between the sliding element 10 and the guiding element 20. The buckle assembly of this embodiment may have a smaller thickness. With the wing 220, the buckle assembly of this embodiment still has good stability.
