Description

[Technical field]

[0001] TECHNICAL FIELD The present disclosure relates to the technical field of buckles, and more particularly to an adjustable position buckle assembly and a baby carrier including the same. [Background technology]

[0002] A baby carrier, such as a stroller, is a device for carrying a baby (including infants, toddlers, children, etc.). A baby carrier is usually provided with wheels and a seat. The seat may include a cushion and a backrest. The cushion is used to support the baby's legs and hips, and the backrest is used to support the baby's back and head. The wheels allow the baby carrier to be pushed conveniently. The seat is usually equipped with a safety belt to restrain the baby and ensure its safety when pushing the baby carrier. The safety belt may be a shoulder belt, a waist belt, a stomach belt, etc., and it restrains various parts of the baby's body.

[0003] Prior art baby carriers may have adjustable shoulder belts. An upper end of the shoulder belt may be connected to an adjustment buckle slidably disposed on the adjustment belt. Both ends of the adjustment belt are connected to a backrest. Because the adjustment buckle is slidable on the adjustment belt, the position of the upper end of the shoulder belt is adjustable to accommodate different sized babies. The backrest of the baby carrier is usually provided with a back cushion to provide a softer feel. The back cushion may have a slit for one end of the shoulder belt and the adjustment buckle to pass through. Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional technology, when the shoulder belt passes through the slit, the slit will come apart, making the slit hard to see, and the backrest may be partially exposed, which often causes poor contact at the slit. If a small cushion is attached, the shoulder belt will not fit the small cushion well, which will mess up the appearance of the baby carrier. In addition, the shoulder belt of the existing baby carrier needs to be removed together with the buckle, which is very inconvenient to use. This operation is inconvenient and does not allow the height of the shoulder belt to be adjusted quickly. [Means for solving the problem]

[0005] The present disclosure provides a buckle assembly including a slide element and a guide element, the slide element including a first fitting portion and the guide element including a second fitting portion, one of the first fitting portion and the second fitting portion receiving the other, such that the slide element is connected to the guide element and the slide element is linearly slidable on the guide element.

[0006] The present disclosure provides a baby carrier including a frame, a backrest, a back cushion, a belt, and the buckle assembly, wherein the backrest is connected to the frame, the back cushion has a slit and at least partially covers the backrest, the belt has an end attached to the frame, and the buckle assembly connects the other end of the belt to the backrest, passes through the slit in the back cushion, connects the other end of the belt to the backrest, and adjusts the height of the other end of the belt.

[0007] The present disclosure provides a slide element including a first fitting portion, the first fitting portion further including a connecting buckle and a neck, the neck connecting the connecting buckle to the first fitting portion, and a width of the neck being smaller than a width of either the connecting buckle or the first fitting portion.

[0008] Various objects, features and advantages of the present disclosure will become more apparent from the following detailed description of preferred embodiments thereof, taken in conjunction with the accompanying drawings, which are merely exemplary illustrations of the present disclosure and are not necessarily drawn to scale, in which the same reference numbers always refer to the same or similar parts.

[0018] 1 and 9-11, the buckle assembly may include a slide element 10 and a guide element 20. The slide element 10 may include a first fitting portion 130. The guide element 20 may include a second fitting portion 210. One of the first fitting portion 130 and the second fitting portion 210 may be formed as a tubular element, while the other of the first fitting portion 130 and the second fitting portion 210 may be formed as an annular element. In the first embodiment, the first fitting portion 130 may be formed as an annular element, and the second fitting portion 210 may be formed as a tubular element. As shown in FIG. 2, the first fitting portion 130 formed as an annular element may have a substantially C-shaped cross section and may have an opening 131 formed therein. The annular element may have a large width so as to be formed in the shape of a sleeve. The annular element may also have a small width to form a C-ring. The tubular element may have a substantially cylindrical shape and may be solid or hollow. The internal shape of the first fitting part 130 formed as an annular element can correspond to the external shape of the second fitting part 210 formed as a tubular element to form a snap engagement, i.e. the second fitting part 210 can be received in the first fitting part 130 to form a connection between the slide element 10 and the guide element 20. Optionally, the tubular element can form an external shape of another shape, such as a regular hexagon, which can to some extent prevent the first fitting part 130 from rotating relative to the second fitting part 210.

[0019] 1 and 8, the first fitting part 130 formed as an annular element can accommodate the second fitting part 210 formed as a tubular element such that the slide element 10 is connected to the guide element 20 and can slide linearly on the guide element 20.

[0020] 1 to 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 to the first fitting portion 130. The sliding element 10 may be integrally formed. The width of the neck 120 may be smaller than the width of either the connecting buckle 110 or the first fitting portion 130. The width may refer to the size in the left-right direction as shown in FIG. 2.

[0021] 8, the guide element 20 may further include a connecting portion 230. The width of the connecting portion 230 may be smaller than the width of the second fitting portion 210. The width may refer to the size in the left-right direction as shown in FIG.

[0022] 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 guide element 20 may be formed in an elongated shape. The two guide elements 20 may be symmetrically arranged on the backrest 80 (e.g., by wings, adhesive, etc.). The guide elements 20 may be arranged substantially vertically or slightly inclined. The connecting buckle 110 of the sliding element 10 is slidably connected to the belt 30. The belt 30 may be a shoulder belt of the baby carrier for restraining the shoulders of a passenger and protecting the safety of the passenger. The belt 30 may be a braided belt. The buckle assembly may also include an adjustment buckle 40. The connecting buckle 110 may include a through hole 111. One end of the belt 30 may pass through the adjustment buckle 40, then pass through the through hole 111, and finally pass through the adjustment buckle 40 again. The adjustment buckle 40 can apply a certain clamping force to the belt 30 so that the belt 30 keeps a distance located between the adjustment buckle 40 and the guide element 20. In other words, the adjustment buckle 40 can be used to adjust the position of the belt 30 passing through the through hole, and thus the adjustment buckle 40 can be used to adjust the looseness of the belt 30 with respect to the baby carried on the baby carrier. The adjustment buckle 40 can be, for example, a common "day" type (two holes) or "eye" type (three holes) buckle. The other end of the belt 30 can be connected to the frame or cushion of the baby carrier. In this way, one end of the belt 30 can move on the backrest 80 through the buckle assembly, and the other end of the belt 30 is fixedly connected to the baby strap, allowing the belt 30 to adapt to babies or children with different shoulder heights.

[0023] 9 shows only one adjustment buckle 40 and belt 30, this is simply to better illustrate the sliding element 10. In actual use, the right-hand sliding element 10 is also connected to a belt 30 and an adjustment buckle 40.

[0024] Referring to FIG. 10, the baby carrier includes a back cushion 90 provided on one 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 can have a size that completely covers the backrest 80 and can have a shape corresponding to the backrest 80. The back cushion 90 can be located between the passenger's back and the backrest 80. The back cushion 90 can be flexible to provide a comfortable feeling. A slit 910 can be formed on the back cushion 90. The number of the slits 910 can correspond to the number of buckle assemblies, for example, two, but the present disclosure is not limited thereto. In this embodiment, the two slits 910 are symmetrically arranged on the backrest 90. The slits 910 can be elongated and can extend in a direction that substantially coincides with the guide element 20. The length of the slits 91 can be equal to or less than the length of the guide element 20. The slits 910 shown in FIG. 10 may have a fixed width, or portions on either side of the slits 910 may overlap each other to visually prevent objects behind the slits 910 from being seen, improving the aesthetics of the baby carrier.

[0025] Referring to FIG. 11, the neck 120 of the sliding element 10 can pass through the slit 910 so that the connecting buckle 110 is located below the backrest 90 (according to the perspective view shown in FIG. 11) and the first fitting portion 130 is located above the backrest 90 (according to the perspective view shown in FIG. 11). The neck 120 is thinner than the connecting buckle 110 and the first fitting portion 130, so that the slit 910 is not significantly deformed by the neck 120 passing through it. This allows the appearance of the back cushion 90 at the slit 910 to be kept beautiful. The connecting buckle 110 can be formed as a rectangular sheet. The connecting buckle 110 can cover the position where the neck 120 passes through the slit 910. Therefore, even if the slit 910 is slightly deformed by the neck 120 passing through it, the deformed portion is covered by the connecting buckle 110 without affecting the appearance of the baby carrier. The thickness of the connecting buckle 110 can be formed to facilitate finger gripping and movement.

[0026] 11, the opening 131 may be formed on the side of the first fitting portion 130 farther from the neck 120. The size of the opening 131 may correspond to the size of the connecting portion 230. The internal space of the first fitting portion 130 may match the external contour of the second fitting portion 210. This allows the sliding element 10 to slide smoothly on the guide element 20. The size of the opening 131 is smaller than the size of the second fitting portion 210 so that the first fitting portion 130 and the second fitting portion do not come off from each other.

[0027] The second embodiment of the present disclosure will now be described.

[0028] FIG. 12 is an oblique view of a slide element of a buckle assembly according to a second embodiment of the present disclosure, FIG. 13 is a plan view of the slide element of a buckle assembly according to the second embodiment of the present disclosure, FIG. 14 is a side view of the slide element of a buckle assembly according to the second embodiment of the present disclosure, and FIG. 15 is a front view of the slide element of a buckle assembly according to the second embodiment of the present disclosure.

[0029] 12 to 15, the main difference between the second embodiment and the first embodiment of the present disclosure is that the connection buckle 110 further includes a lock portion 112. The lock portion 112 may be a rod provided in the through hole 111. The belt 30 penetrates the through hole 111 from one side of the lock portion 112 in a first direction, and further penetrates the through hole from the other side of the lock portion 112 in a second direction opposite to the first direction. In other words, the connection buckle 110 can simultaneously have the function of adjusting the adjustment buckle 40 via the lock portion 112. In this way, the buckle assembly of the second embodiment of the present disclosure does not need to include the adjustment buckle 40.

[0030] The locking portion 112 can be formed with a plurality of protrusions and a plurality of recesses alternately. In other words, the locking portion 112 can be formed with an uneven shape to increase the friction force. Other methods can be used to increase the friction force, such as protrusions or stripes, to form the locking portion 112, or other materials with higher friction force, such as rubber, can be used to form the locking portion 112.

[0031] The connecting buckle 110 further includes an operating portion 114. The operating portion 114 can be formed as a lug protruding from one side (e.g., the lower side in Figs. 12, 15, 24) of the connecting buckle 110. The operating portion 114 can be grasped by the user's fingers to easily move the sliding element.

[0032] The third embodiment of the present disclosure will now be described.

[0033] FIG. 16 is an oblique view of a slide element of a buckle assembly according to a third embodiment of the present disclosure, FIG. 17 is a top view of a slide element of a buckle assembly according to a third embodiment of the present disclosure, FIG. 18 is a side view of a slide element of a buckle assembly according to a third embodiment of the present disclosure, FIG. 19 is a front view of a slide element of a buckle assembly according to a third embodiment of the present disclosure, FIG. 24 is an exploded oblique view of a slide element of a buckle assembly according to a third embodiment of the present disclosure, and FIG. 25 is a schematic oblique view of a slide element of a buckle assembly according to the third embodiment of the present disclosure.

[0034] 16-20 and 24-25, the third embodiment of the present disclosure differs from the second embodiment in that a pivot shaft 121 can be formed in the neck 120 of the sliding element 10. A pivot hole 113 can be formed in the connecting buckle 110. The pivot shaft 121 can be positioned in the pivot hole 113 so that the connecting buckle 110 can rotate relative to the neck 120. Since the connecting buckle 110 is rotatable relative to the neck 120, for example, the connecting buckle 110 can be rotated to a suitable angle (as shown in FIG. 25), and an operator can grasp / hold the lower part of the connecting buckle 110 with the thumb and index finger to move the sliding element 10 more conveniently or adjust the seat belt 30. Also, since the connecting buckle 110 is rotatable relative 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 is rotatable relative to the neck 120 in the direction of the arrow.

[0035] The fourth embodiment of the present disclosure will be described below.

[0036] FIG. 21 is a schematic diagram of a buckle assembly according to a fourth embodiment of the present disclosure.

[0037] Referring to FIG. 21, the fourth embodiment of the present disclosure differs from the first embodiment in that the guide element 20 may also include a wing 220. The wing 220 may be formed on the opposite side of the connecting portion 230 to the second fitting portion 210, and the wing 220 may be formed as a sheet perpendicular to the connecting portion 230. That is, as shown in FIG. 21, the wing 220 is formed as a horizontal sheet. The connecting portion 230 extends upward perpendicularly to the wing 220. The second fitting portion 210 is located at the upper end of the connecting portion 230. The wing 220 may be formed, for example, in a square, rectangular, or circular shape, but the shape of the wing 220 is not limited in the present disclosure. The wing 220 can hold the second fitting portion 210 in a more stable upright position to prevent the second fitting portion 210 from being moved and tilted by external force and coming into contact with the backrest 80, and can prevent any effect on the connection between the second fitting portion 210 and the first fitting portion 130.

[0038] Next, a fifth embodiment of the present disclosure will be described.

[0039] FIG. 22 is a schematic diagram of a buckle assembly according to a fifth embodiment of the present disclosure.

[0040] 22, the fifth embodiment of the present disclosure differs from the fourth embodiment in that the slide element 10 can include two first fitting parts 130 and two necks 120, and the guide element 20 can include two second fitting parts 210 and two connecting parts 230. The two first fitting parts 130 can be connected to the two second fitting parts 210, respectively. The wing 220 can connect the two connecting parts 230. In this embodiment, the connection positions between the slide element 10 and the guide element 20 are more than other embodiments, so that the connection between the slide element 10 and the guide element 20 is more stable. Optionally, the slide element 10 can include more than two first fitting parts 130 and more than two necks 120, and the guide element 20 can include more than two second fitting parts 210 and more than two connecting parts 230.

[0041] Next, a sixth embodiment of the present disclosure will be described.

[0042] FIG. 23 is a schematic diagram of a buckle assembly according to a sixth embodiment of the present disclosure.

[0043] With reference to FIG. 23, the sixth embodiment of the present disclosure differs from the fourth embodiment in that the first fitting portion 130 can be formed as a tubular element, and the second fitting portion 210 can be formed as an annular element. The second fitting portion 210 formed as an annular element can form an opening on the upper side, and the wings 220 can extend horizontally from both sides of the opening to the left and right sides thereof. That is, the guide element 20 may only have the second fitting portion 210 and the wings 220, and may not have the connection portion 230. The first fitting portion 130 formed as a tubular element is formed at the lower end of the neck 120. The first fitting portion 130 is received by the second fitting portion 210 and forms a connection between the slide element 10 and the guide element 20. The buckle assembly of this embodiment can have a smaller thickness. Due to the wings 220, the buckle assembly of this embodiment still has good stability.

[0044] 26 is a perspective view of an example of a carrier of the present disclosure.

[0046] Next, seventh to ninth embodiments of the present disclosure will be described.

[0047] 27A to 32 show the seventh embodiment of the present disclosure. Next, the differences between the seventh embodiment and the first embodiment will be described.

[0048] As shown in Figures 27A and 28D, the second fitting portion 210 can have a plurality of grooves 211 formed along its longitudinal direction. The plurality of grooves 211 may be provided on the side of the second fitting portion 210. The plurality of grooves 211 may be provided at equal intervals on the second fitting portion 210. Optionally, the plurality of grooves 211 may be provided at different intervals on the second fitting portion 210.

[0049] As shown in FIG. 30, the second fitting portion 210 may be formed on the upper side of the connection portion 230, and the wing 220 may be formed on the lower side of the connection portion 230. The wing 220 may be formed as a sheet perpendicular to the connection portion 230. As shown in FIG. 30, the wing 220 is formed in a horizontal sheet or flat plate shape. The connection portion 230 extends upward perpendicular to the wing 220. The second fitting portion 210 is located at the upper end of the connection portion 230. The wing 220 may be rigid and may be fixed to the backrest 80, thereby preventing the second fitting portion 210 from being moved and tilted by an external force and from contacting the backrest 80, thereby preventing the connection between the second fitting portion 210 and the first fitting portion 130 from being affected by the wing 220, by holding the second fitting portion 210 in an upright state more stably. 30, in the seventh embodiment, the wing 220 extends horizontally to the right from the lower end of the connecting portion 230. Optionally, the wing 220 extends horizontally to the left and right simultaneously from the lower end of the connecting portion 230.

[0050] 29 and 32, the finger portion 132 can be formed on the first fitting portion 130. The finger portion 132 can be located in the center in the longitudinal direction of the first fitting portion 130. The finger portion 132 may also be located on a side of the first fitting portion 130.

[0051] 28A to 28D, 29, and 30, the finger portion 132 extends from the neck 120 and has a free end separated from the other portion of the first fitting portion 130. Thus, the finger portion 132 has elasticity in the direction toward and away from the second fitting portion 210.

[0052] As shown in FIGS. 28A-28D and 29, the finger portion 132 may have a boss 1321 formed on the inner side thereof, protruding inward. When the slide element 10 slides on the guide element 20, the finger portion 132 of the slide element 10 may engage with one of the grooves 211. Specifically, the boss 1321 of the finger portion 132 may have an interference fit with the groove 211 to provide additional resistance to the sliding of the slide element 10 on the guide element 20. Here, a preferred interference amount of the interference fit is 0.7 mm, but the present disclosure is not limited thereto. An interference amount can be provided to make the clamp position tighter. When the force applied to the slide element 10 along the second fitting portion 210 exceeds a threshold value, the finger portion 132 is elastically deformed, and the boss 1321 is released from the groove 211.

[0053] Optionally, the fingers 132 are rotatably connected to the neck 120. The first fitting portion 130 may include an actuator (not shown). The actuator may be manipulated to rotate the fingers 132 away from the second fitting portion 210, actively moving the bosses 1321 of the fingers 132 away from the grooves 211.

[0054] In the seventh embodiment, the fixing force between the sliding element 10 and the guide element 20 can be increased by the joint between the finger portion 132 and the groove 211. The grooves 211 on the second fitting portion 210 allow the operator to feel the distance the sliding element 10 moves. The actuation portion can disengage the finger portion 132 from the groove 211 more easily.

[0055] In the seventh embodiment, a single adjustment buckle 40 (see FIG. 9) is required to adjust the length of the belt 30.

[0056] The buckle assembly of this embodiment has a simple appearance and is convenient to operate.
