Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priorities to Chinese Application No. 202411142686.8, entitled “connecting device for a child carrier and child carrier” and filed on Aug. 19, 2024; and Chinese Application No. 202411216333.8, entitled “child crib” and filed on Aug. 30, 2024, which are all incorporated herein by reference in their entireties.

TECHNICAL FIELD

The present disclosure relates to a connecting device for a child carrier and a child carrier, and the present disclosure further relates to a child crib, and particularly to a child crib with anti-pinch device.

BACKGROUND

Child carriers, such as baby cribs and child cribs, provide a space for babies to sleep and play. To enhance functional versatility, these cribs may be detachably connected to various accessories (e.g., changing tables, bassinets, or bouncer seats). However, existing accessory connection mechanisms often employ rotary-operated components. When the accessory is unlocked, a direction of force applied to the operating member is different from a direction where the accessory is detached, which makes the operation laborious and inconvenient to use.

In addition, to facilitate storage and transportation, the child cribs are usually designed to be foldable. In this way, the child crib may be folded when it is not in use temporarily and when it is being transported, in order to save space.

A foldable child crib may generally include upright posts, bottom tubes, and handrail tubes. The handrail tubes and bottom tubes may be folded relative to the upright posts. The child crib also includes a seat cloth surrounding the upright posts, bottom tubes, and handrail tubes. Therefore, when the child crib is folded, the seat cloth is prone to getting caught in a gap between the handrail tube and the upright post, and the gap between the handrail tube and the upright post is also likely to pinch an operator's fingers, which affects the folding of the child crib and causes safety accidents.

FIGS. 1 to 4 show a child carrier according to one embodiment and a perspective view of the carrier body A10 and an accessory A20 of the child carrier, respectively.

FIG. 1 shows a perspective view of the child carrier according to one embodiment. The child carrier, for example, is a baby crib A1, which provides a space for a baby to sleep and play. The child carrier mainly includes a carrier body A10. For ease of disassembly and storage, the carrier body A10 may be assembled through a plurality of rods and connected through a plurality of joints A130. The rods include, for example, a plurality of first rods A100 that form a rectangular frame. The first rods A100 form an upper part of the carrier body A10 to serve as an upper frame onto which a child may hold. At the joints A130 located at the four corners of the upper frame formed by the first rods A100, four legs A110 in the form of rods are inserted and connected. The legs A110 are configured to support the child carrier on the ground. To make the four legs A110 stand more stably, rods in the form of supporting members A120 may be provided between the four legs A110 to form a bottom frame of the baby crib A1. According to this embodiment, one end of each of the plurality of supporting members A120 is inserted into a joint A130, and the other end of each of the plurality of supporting members A120 is, for example, fixed to a lower end of the leg A110 by a bolt. According to the present disclosure, a seat cloth may be encased around the baby crib A1 to form a space for infants and young children to play and rest, and also to serve aesthetic purposes.

According to the present disclosure, the joint A130 may take various forms to enable the rods to be assembled into a detachable child carrier. With respect to the specific form of the joint A130, the present disclosure is not limited to the drawings.

According to FIG. 1, in the case that the baby crib A1 is not used for a baby to sleep, in order to increase versatility of the baby crib A1, a plurality of accessories A20, such as a changing table, a bassinet, and a bouncer, are detachably connected to the baby crib A1. A bouncer is schematically shown on a left side of FIG. 1. It may be formed by a plurality of second rods A200 that form a supporting part, with cantilevers extending downward from the supporting part. The cantilevers of the bouncer may be placed on the ground or a platform for a child to bounce therein. A changing table is schematically shown on a right side of FIG. 1. It may be formed by a plurality of second rods A200 that form a supporting part for supporting and fixing the main body of the changing table that carries a child, such as a panel and a cushion. The second rods A200 forming the bouncer may be of the same form as those forming the changing table in order to be easily manufactured.

According to the present disclosure, the bouncer and the changing table are mounted side by side on the carrier body A10. The changing table has a length L1 and a width W1, and the bouncer has a length L2 and a width W2. The length L1 is substantially equal to the length L2. Since the rods are substantially of the same form, this allows the bouncer and the changing table to be detachably fixed, for example, engaged to the first rods A100 of the carrier body A10 using the same connecting device A30. According to this embodiment, one connecting device A30 is provided on each of the two sides of the bouncer and the changing table in a direction of the lengths L1 and L2. An internal structure of the connecting device A30 is described in detail in FIGS. 8 to 10 according to the section lines I-I, II-II, III-III, and IV-IV of the local part A in FIG. 1.

Optionally, the width W1 of the changing table may be equal to the width W2 of the bouncer so that each accessory A20 has substantially the same profile dimensions.

FIG. 2 shows a perspective view of the carrier body A10 of a child carrier according to one embodiment. With the changing table and bouncer (jump chair) removed in FIG. 2, a shape of the carrier body A10 can be better seen. The upper frame, for example, is composed of eight first rods A100, with a joint A130 provided between every two first rods A100. The connection between the joint A130 and the first rod A100 may be in the form of insertion, hinging, pivoting, etc., thereby forming a rectangular upper frame. The legs A110 may be pivotally connected to the supporting members A120 via a bolted connection part, so that the legs A110 and the supporting members A120 may be folded together when not in use.

According to this embodiment, at a position of the first rod A100 for connecting the accessory A20 shown in FIG. 1, that is, at a position of the connecting device A30, an engaging part A101 for positioning and engaging the connecting device A30 of the accessory A20 is provided. According to this embodiment, the engaging part A101 is provided outwardly on the first rod A100, providing a positioning and engaging location for the connecting device A30 of the bouncer and the changing table. Certainly, the engaging part A101 may also be provided inwardly on the first rod A100, the present disclosure is not limited thereto. According to this embodiment, the engaging part A101, for example, is an engaging recess, and the number thereof is two, to provide more stable positioning and engaging. Certainly, the form and number of the engaging part A101 are not limited thereto. For example, the engaging part A101 may be in the form of an engaging protrusion, and the number of the engaging part A101 may be three, four, or more. On the first rod A100 on the other side of the carrier body A10, the engaging part A101 is provided in a symmetrical manner. The engaging part A101 is capable of being cooperated with the corresponding engaging structure provided on the connecting device A30 (to be described later) to position and engage the connecting device A30 to the first rod A100. Thus, when the accessory A20 is mounted on the carrier body A10, the corresponding engaging structure on the connecting device A30 may be only engaged with the carrier body A10 when aligned with the engaging part A101, thereby providing a stable and distinct mounting part for the accessory A20.

FIG. 3 shows a top perspective view of the accessory A20 according to one embodiment, taking the changing table as an example. The main body of the accessory A20 is a supporting part, which includes a plurality of second rods A200, and may also be formed by bending a single second rod A200. The supporting part forms a rectangular frame structure. A connecting device A30 is provided on each of the two opposite sides of the accessory A20, so as to be engaged and mounted to the first rod A100 of the carrier body A10 (see FIGS. 1 and 2). According to this embodiment, the connecting device A30 is provided on the second rod A200, for example, the second rod A200 passes through the connecting device A30 and is connected thereto, and optionally is fixedly connected to the connecting device A30.

According to this embodiment, the connecting device A30 includes a fixing base A310 and a cover part A300. The cover part A300 is cooperated with the fixing base A310 so that the second rod A200 passes through and is connected to the connecting device A30. The fixing base A310 and the cover part A300 may be fitted, adhesively bonded, bolted, etc. As can be seen from FIG. 3, in order to better hold the second rod A200, the fixing base A310 and the cover part A300 together form a receiving part corresponding to the cross-sectional shape of the second rod A200, that is, for example, the fixing base A310 and the cover part A300 may each have a semi-circular structure. In other embodiments, the fixing base A310 and the cover part A300 may be integrally formed.

According to this embodiment, an engaging groove A320 is provided on a side of the fixing base A310 away from the second rod A200. The engaging groove A320 is open in a vertical direction and extends in the extension direction of the second rod A200. Thus, when the connecting device A30 is engaged to the carrier body A10, the engaging groove A320 may be seated on the first rod A100 of the carrier body A10, in other words, a part of segment of the first rod A100 may be accommodated in the engaging groove A320. In the state where the accessory A20 and the carrier body A10 are assembled, the first rod A100 and the second rod A200 are parallel to each other (see FIG. 1). Certainly, the first rod A100 and the second rod A200 may not be parallel to each other, for example, the second rod A200 may be wing-shaped on both sides of the connecting device A30.

The connecting device A30 also includes an accommodating part A330, which is provided on the fixing base A310 to accommodate the operating member A340. The operating member A340 is configured to unlock locking between the accessory A20 and the carrier body A10. The structure and operation of the operating member A340 will be described in detail later with reference to FIGS. 5 to 15.

FIG. 4 shows a bottom perspective view of the accessory A20 according to one embodiment. From the connecting device A30 at a lower left, the accommodating part A330 can be seen, which is in the form of a recess in the fixing base A310. The main portion of the operating member A340 is accommodated in the accommodating part A330 and may slide within the accommodating part A330 relative to the fixing base A310. The operating member A340 is partially exposed from the accommodating part A330 when not operated. Optionally, the operating member A340 is shaped to match the accommodating part A330.

A connecting hole may be provided inside the engaging groove A320, for passing through an additional fixing device, such as a screw, rivet, etc., to additionally fix the fixing base A310 to the second rod A200 or the cover part A300.

From the connecting device A30 at an upper right of FIG. 4, the engaging rib A321 provided in the engaging groove A320 can be schematically seen. According to this embodiment, two engaging ribs A321 are laterally arranged in the engaging groove A320. The width of the engaging rib A321 corresponds to the width of the engaging part A101 shown in FIG. 2, so as to preliminarily position and engage the connecting device A30.

FIGS. 5 to 15 show a sectional view and a perspective view of the connecting device A30 according to one embodiment, respectively.

FIG. 5 shows a bottom partial sectional view of a child carrier according to one embodiment along the section line I-I of FIG. 1, cut parallel to the ground in FIG. 1 at the first rod A100. The first rod A100 is positioned between the fixing base A310 and the cover part A300 of the connecting device A30. The first rod A100 is provided with two engaging parts A101 (in the form of engaging recesses), each of which is aligned with and engaged with the engaging rib A321 (illustratively shown) that is provided in the engaging groove A320. If the engaging parts A101 and the engaging ribs A321 are not aligned when the accessory A20 is assembled, or if an incompatible accessory A20 is used, the accessory A20 cannot be stably mounted on the first rod A100. The present disclosure avoids a risk of children being injured due to being in an unstable accessory A20 by the cooperation of the engaging ribs A321 and the engaging parts A101.

As shown in FIG. 5, the fixing base A310 also includes a sliding rail A350, which extends perpendicular to a plane of a paper in the drawing. In a use state of the child carrier, the sliding rail A350 optionally extends in the vertical direction. Optionally, the sliding rail A350 is formed on the inner edge A331 of the accommodating part A330, protruding inward from the inner edge A331 of the accommodating part A330. The operating member A340 may be provided with a sliding groove A348 that corresponds in shape to the sliding rail A350. The sliding rail A350 is slidably accommodated in the sliding groove A348 (for example, forming a dovetail joint), thereby allowing the operating member A340 to slide in a direction perpendicular to the plane of the paper along the sliding rail A350 without disengaging or deviating from the accommodating part A330. Certainly, it is also possible that the fixing base A310 is provided with a sliding groove, and the operating member A340 is provided with a sliding rail, which can also achieve the technical effect of the operating member A340 sliding relative to the fixing base A310.

According to this embodiment, the operating member A340 includes a mounting groove A342 for mounting and fixing the driving member A370. The mounting groove A342 is provided in a direction perpendicular to the plane of the paper in FIG. 5 and will be described in detail later with reference to FIG. 13.

The two ends of the driving member A370 are respectively connected to the engaging member A380 and the operating member A340. The driving member A370 includes a driving member body A371. The both sides of the ends of the driving member body A371 are provided with connecting protrusions A373. The connecting protrusions A373 are configured in a cylindrical shape to facilitate insertion into the engaging member A380 or the operating member A340 and to pivot therein, thereby allowing the driving member A370 to rotate relative to the engaging member A380 and/or the operating member A340. Optionally, in this embodiment, the structure and shape of the two ends of the driving member body A371 are the same, and corresponding connection structures are provided on the engaging member A380 and the operating member A340. In other embodiments, the structure and shape of the ends of the driving member body A371 may not be the same. For example, the connecting protrusion A373 described above is provided at one end configured to connect to one of the engaging members A380 and the operating member A340, and the other end is constructed as another connection structure.

Optionally, two opposed branching parts A372 are provided at the end of the driving member body A371. The connecting protrusion A373 is provided outside each branching part A372. The opposed branching parts A372 are spaced apart to form a deformation space A374. When the driving member A370 is connected to the engaging member A380 and/or the operating member A340, the two opposed branching parts A372 are pressed towards each other to be deformed. After the two ends of the driving member A370 are inserted into the engaging member A380 and/or the operating member A340 and the connecting protrusion A373 is located in the connection structure inside the engaging member A380 and/or the operating member A340, the branching parts A372 move away from each other and return from the deformed state to the original state, thereby completing the assembly of the driving member A370 with the engaging member A380 and/or the operating member A340.

As shown in FIG. 7, the assembly state of the driving member A370 and the engaging member A380 is illustrated as an example of the assembly of the driving member A370 and the engaging member A380. The engaging member A380 is configured to be elongated. One end of the driving member A370 is inserted into the engaging member A380 through the connecting protrusion A373, so that when the driving member body A371 of the driving member A370 needs to pivot relative to the engaging member A380, the connecting protrusion A373 of the driving member A370 may serve as a pivoting point in the connecting hole A384. The assembly structure of the driving member A370 and the engaging member A380 is similar to the assembly structure of the operating member A340 and the driving member A370, which will be described later with reference to FIG. 13.

The engaging member A380 is provided with a pivoting shaft A381 and a limiting protrusion A382 on each of its two end sides. The pivoting shaft A381 and the limiting protrusion A382 are cooperated with the fixing base A310, which will be described in detail later with reference to FIGS. 14 and 15.

FIG. 8 shows a top partial sectional view of a child carrier according to one embodiment along the section line II-II of FIG. 1, with the section taken between the engaging groove A320 and the second rod A200. The main body of the engaging member A380 is located in the moving chamber A311. The end of the driving member A370 away from the engaging member A380 is inserted into the mounting groove A342 of the operating member A340. The protrusion A355 at this end is located and pivotable in the connecting hole A343 of the operating member A340. As shown in FIGS. 9 and 11, the engaging member A380 is movably disposed within the moving chamber A311. Specifically, the engaging member A380 is rotatably disposed in the moving chamber A311 to enable the conversion of the engaging member A380 between the locked position and the unlocked position.

FIG. 8 also shows a limiting block A344, which is connected to the operating member A340 or formed as a part of the operating member A340 and is located in a gap between the two sliding rails A350. Referring to FIG. 10, when the operating member A340 slides downward, the limiting block A344 is capable of abutting against the abutting part A334 of the accommodating part A330 to restrict the operating member A340 from continuing to move downward and prevent the operating member A340 from disengaging from the fixing base A310.

FIG. 9 shows a sectional view of the connecting device A30 in the locked position according to one embodiment along the section line III-III of FIG. 1, which is located at the mounting groove A342 in FIG. 8. FIG. 10 shows a sectional view of the connecting device A30 in the locked position along the section line IV-IV of FIG. 1, with the first rod A100 and the joint A130 of the carrier body A10 removed. FIG. 11 shows a sectional view of the connecting device A30 in the unlocked position according to one embodiment along the section line III-III of FIG. 1. FIG. 12 shows a sectional view of the connecting device A30 according to yet another embodiment.

The first rod A100 is slidably received in the upper part of the engaging groove A320 of the connecting device A30. The second rod A200 is fixedly held by the cover part A300 and the fixing base A310. Optionally, the first rod A100 and the second rod A200 are located on the same vertical plane, and the first rod A100 may slide up and down along the vertical plane relative to the engaging groove A320 to be disengaged from the engaging groove A320. In other embodiments, the first rod A100 and the second rod A200 may not be located on the same vertical plane.

The accommodating part A330 of the connecting device A30, which is configured to accommodate the operating member A340, is located on a side of the fixing base A310 away from the first rod A100 and the second rod A200. The operating member A340 may slide up and down within the accommodating part A330 along the sliding rail A350 formed by the inner edge A331 of the accommodating part A330, as shown in FIGS. 5 and 8. A direction of the up-and-down sliding is parallel to the vertical plane in which the first rod A100 and the second rod A200 are located. In other embodiments, the sliding direction of the operating member A340 may not be along the vertical direction but be inclined relative to the vertical direction.

According to this embodiment, one end of the driving member A370 is pivotally connected to the mounting groove A342 of the operating member A340. The driving member body A371 of the driving member A370 passes through the opening A332 shown in FIGS. 5 and 6. The other end of the driving member A370 is pivotally connected to the engaging member A380. The engaging member A380 is rotatable in the moving chamber A311 of the fixing base A310.

FIGS. 9 and 10 show the locked position of the connecting device A30. When the operating member A340 slides downward, the operating member A340 causes one end of the driving member A370 to pivot and slide downward. The driving member body A371 rotates clockwise to cause the other end of the driving member A370 to pivot relative to the engaging member A380 and to push the end of the engaging member A380 out of the moving chamber A311 into the engaging groove A320, to abut against the lower side of the first rod A100. This can prevent the first rod A100 from sliding relative to the engaging groove A320 and disengaging from the fixing base A310, that is, the first rod A100 is locked within the engaging groove A320.

FIG. 11 shows the unlocked position of the connecting device A30. When the user presses the operating member A340 upward to cause the upper end of the operating member A340 to approach the upper edge A333 of the accommodating part A330, the operating member A340 causes one end of the driving member A370 to pivot and slide upward. The driving member body A371 rotates counterclockwise to cause the other end of the driving member A370 to pivot relative to the engaging member A380 and to pull the end of the engaging member A380 back into the moving chamber A311 of the fixing base A310 from the locked position shown in FIG. 9. The first rod A100 may slide downward along the engaging groove A320 relative to the fixing base A310 to be disengaged from the fixing base A310.

As shown in FIGS. 9 and 10, the upper end of the operating member A340 is provided with a cushion resetting member A341, which may be, for example, a leaf spring. One end of the leaf spring abuts against the upper end of the operating member A340, and the other end of the leaf spring, for example, is wound around the second rod A200. Alternatively, referring to FIG. 12, the cushion resetting member A341 may also be configured as a helical spring, which is provided in a recess A349 formed at the upper end of the operating member A340, and the upper end is limited by the protrusion A335 provided at the upper edge A333 of the accommodating part A330.

The lower end of the operating member A340 is provided with a limiting block A344. The limiting block abuts against the abutting part A334 formed by the inner edge A331 of the accommodating part A330 to restrict the downward sliding movement of the operating member A340 relative to the fixing base A310 and prevent the operating member A340 from disengaging from the fixing base A310.

When the user presses the operating member A340 to slide upward, the cushion resetting member A341 acts as a cushion to prevent the operating member A340 from rigidly abutting against the upper edge A333 of the accommodating part. When the user releases the operating member A340 or no external force is applied to the operating member A340, the cushion resetting member A341 biases the operating member A340 to cause the engaging member A380 to have a tendency to move toward the locked position. In this case, the operating member A340 is reset downward by the elastic force of the cushion resetting member A341 until the limiting block A344 abuts against the abutting part A334.

FIG. 13 shows a sectional view of the connecting device A30 according to the section line V-V of FIG. 10. The operating member A340 includes a sliding groove A348, in which the sliding rail A350 of the connecting device A30 is located, such that the operating member A340 may slide up and down along the sliding rail A350. Optionally, the sliding groove A348 is provided in two, but may also be provided in one or more than two.

The operating member A340 also includes a mounting groove A342 and a connecting hole A343 for mounting and positioning the driving member A370. The mounting groove A342 is provided along the vertical direction, and the connecting hole A343 is provided in a horizontal direction and intersects with the mounting groove A342. Referring to FIG. 5, the mounting groove A342 is substantially aligned with the opening A332 provided in the inner edge A331 of the accommodating part A330. The opening A332 and the mounting groove A342 together form a passage for passing through the driving member A370. The main body A371 of the driving member A370 spans across the opening A332 and the mounting groove A342, so that one end of the driving member A370 is pivotally connected to the operating member A340, and the other end of the driving member A370 is pivotally connected to the engaging member A380. The mounting groove A342 is provided with a reduced-diameter portion close to the lower part close to the connecting hole A343, that is, at least a part of the mounting groove A342 converges in the vertical direction towards the direction close to the connecting hole A343. The connecting hole A343 is perpendicular to the mounting groove A342. Optionally, for ease of tool processing, the connecting hole A343 passes through the operating member A340 from one side, that is, taking the connecting hole A343 on the left side in FIG. 13 as an example, one end thereof passes through the left side of the operating member A340.

When the driving member A370 and the operating member A340 are assembled, the branching part A372 of the driving member A370, together with the connecting protrusion A373, is placed into the mounting groove A342 from above. When reaching the reduced-diameter part, under the action of an external force (pushing or pulling the driving member A370 downward), the two connecting protrusions A373 are subjected to compressive force, such that the two branching parts A372 may compress the deformation space A374, after the connecting protrusion A373 is inserted into the connecting hole A343, the branching part A372 returns to its original state under its own elasticity, such that the end of the driving member A370 is firmly engaged with the connecting hole A343 of the operating member A340. As described above with reference to FIG. 7, the assembly structure of the driving member A370 and the engaging member A380 is similar to the assembly structure of the operating member A340 and the driving member A370.

As shown in FIGS. 14 and 15, according to this embodiment, the driving member A370 is pivotally connected to the operating member A340 at the pivoting point A345. Optionally, the pivoting point A345 may be formed by the connecting protrusion A373 of the driving member A370 shown in FIGS. 6, 7, and 13 and the connecting hole A343 shown in FIG. 13.

The engaging member A380 may rotate within the moving chamber A311 of the fixing base A310. A guiding part A347 is vertically provided from the bottom of the moving chamber A311, and the guiding part A347 divides the lower part of the moving chamber A311 into a storage part A346. The pivoting shaft A381 of the engaging member A380 is located in the storage part A346, for example, at the bottom of the storage part A346, so that the engaging member A380 may pivot around the pivoting shaft A381. The moving chamber A311 includes limiting walls A312, which are disposed opposite to each other and preferably extend in the vertical direction. When the engaging member A380 is in the locked position, the limiting protrusion A382 abuts against one of the limiting walls A312 of the moving chamber A311, and a part of the engaging member A380 protrudes out of the moving chamber A311 into the engaging groove A320. When the engaging member A380 is in the unlocked position, the engaging member A380 is completely retracted into the moving chamber A311, and the limiting protrusion A382 is rotated to the other side of the moving chamber A311 and abuts against another limiting wall A312 of the moving chamber A311. The cooperation of the limiting protrusion A382 and the pivoting shaft A381 with the fixing base A310 provides more stable controlled movement of the engaging member A380.

Optionally, the child carrier of the present disclosure may also include a carrying part A140. FIG. 16 shows a child carrier including the carrying part A140 according to one embodiment. Unlike FIG. 1, the carrying part A140 for carrying, such as children to sleep or play, is provided on the carrier body A10. The carrying part A140 may be fixedly connected to, for example, the carrier body A10, such as the legs A110, in any manner.

Referring to FIG. 17, the carrying part A140 is formed of a plurality of panels A141. Optionally, the panels A141 are four in number and in the same form. Connecting holes A142 are provided at the edges of each panel A141 for connecting the panels A141 together. The positions of the connecting holes A142 may be adjusted as needed.

FIG. 18 shows a connecting member A143 in the form of a hinge, which is fixedly connected to the panel A141 via the connecting hole A142. FIG. 19 shows a structure of a half of the connecting member A143, which includes a latching part A144. Each connecting member A143 is composed of two halves, and the latching parts A144 of each half are aligned with each other and traversed by a pivoting shaft (not shown), such that the two halves may be pivoted relative to each other to allow the carrying part A140 to be foldable.

The operating member A340 for unlocking the accessory A20 of the baby crib A1 is configured to be slidably connected to the accessory A20, and when the accessory A20 is required to be unlocked, the direction of the force applied to the operating member A340 is consistent with or substantially consistent with the direction of the force used by the user to remove the accessory A20 from the baby crib A1, in this way, the user can more effortlessly and conveniently detach the accessory A20, and the operation is more convenient. Simultaneously, the operating member A340 may cause the engaging member A380 to pivot via the driving member A370, the sliding motion of the operating member A340 is converted to the pivoting motion of the engaging member A380 through the driving member A370. Such structure is simple.

Hereinafter, a child carrier in the form of a child crib is taken as an example to illustrate an anti-pinch device according to the present disclosure. Certainly, the anti-pinch device according to the present disclosure may also be applied to other products that need to be folded.

First, reference is made to FIG. 20, a structural schematic view of a child crib B1′ according to the prior art is shown. As shown in FIG. 20, the child crib B1′ includes four upright posts B12′, upper ends of which are respectively connected to four top corner members B16′. a handrail assembly B18′ is connected between pairs of top corner members B16′ (since the handrail assemblies B18′ are wrapped by the seat cloth, only schematically shown in FIG. 20). When the crib frame is folded, relative motion occurs between the handrail assembly B18′ and the top corner member B16′, and thus a gap between the handrail assembly B18′ and the top corner member B16′ (as indicated by a dashed circle in FIG. 20) presents a risk of pinching the operator's fingers.

To address the aforementioned issues, the structure of the child crib B1 according to the present disclosure is now described in detail with reference to FIGS. 21 and 22. FIG. 21 is a schematic view showing a main structure of the crib frame, while FIG. 22 is a schematic view showing an overall structure of the child crib according to the present disclosure. The child crib B1 mainly includes a crib frame B10 (shown in FIG. 21) and a seat cloth B20 (shown in FIG. 22). The crib frame B10 typically includes four upright posts B12, the upper ends of which are respectively fixedly connected to four top corner members B16. The lower ends of the four upright posts B12 are pivotally connected to the bottom tube B14. In addition, a handrail assembly B18 is connected between pairs of top corner members B16. The upright posts B12, the bottom tubes B14, the top corner members B16, and the handrail assemblies B18 form a generally rectangular crib frame B10. The upright posts B12 are pivotally foldable relative to the top corner members B16 and the bottom tubes B14, such that the crib frame B10 may be folded and facilitate the folding of the child crib B1 for temporary storage or transportation.

The handrail assembly B18 further includes a handrail tube B181 and a handrail seat B182. As shown in FIG. 21, taking one side of the crib frame B10 as an example, the handrail seat B182 is located between two adjacent top corner members B16, and the inner ends of the handrail tube B181 are pivotally connected to the handrail seat B182, while the outer ends of the handrail tube B181 are respectively pivotally connected to the two adjacent top corner members B16. In this way, the handrail tube B181 may be further folded relative to the handrail seat B182, thereby further reducing the size of the crib frame B10 after being folded.

Referring to FIG. 22, the entire crib frame B10 is encased by the seat cloth B20 of the child crib B1 according to the present disclosure. Specifically, the seat cloth B20 includes a side wall seat cloth B22 surrounding the four upright posts B12. Optionally, the seat cloth B20 also includes a bottom wall seat cloth B24 surrounding the bottom tube B14. The side wall seat cloth B22 includes an upper sheath part B223 and a side fence part B221. The upper sheath part B223 is formed by folding the side wall seat cloth B22 outward after passing across the handrail assembly B18 and the top corner members B16. The upper sheath part B223 may be formed by folding outward after passing across the handrail assembly B18 and the top corner members B16 from the inner side thereof, or by folding inward after passing across the handrail assembly B18 and the top corner members B16 from the outer side thereof. The upper sheath part B223 may also be an independent component separate from the side wall seat cloth B22, with the upper sheath part B223 separately encasing the handrail assembly B18. That is, the lower edge B2231a of the inner side part B2231 of the upper sheath part B223 may be fixedly connected to the upper edge of the side fence part B221. The upper sheath part B223 and the side fence part B221 may be made of different materials. For example, the side fence part B221 may be made of mesh to make the child crib B1 more ventilated and comfortable, while the upper sheath part B223 may be made of fabric and may be filled with filling materials. As shown in FIG. 22, the upper sheath part B223 formed by being folded encases both the handrail assembly B18 and the top corner members B16. When the child crib B1 is folded, the upper sheath part B223 may also cover the gap between the top corner members B16 and the handrail assembly B18, thereby avoiding the risk of pinching the operator's fingers in the gap between the handrail assembly B18 and the top corner members B16.

Preferably, the lower edge B2231a of the inner side part B2231 (indicated in FIG. 23) of the upper sheath part B223, which is formed by folding the side wall seat cloth B22 after passing across the handrail assembly B18 and the top corner member B16, is located below the lower edge B182a (indicated in FIG. 21) of the handrail seat B182. This arrangement ensures that the inner side part of the upper sheath part B223 appears neat and aesthetically pleasing. The lower edge B2232a of the outer side part B2232 (indicated in FIG. 23) of the upper sheath part B223 is connected to the side fence part B221 close to the positions connected to the top corner member B16 on both sides. Referring to FIG. 23 (only exemplarily shows one side of the sheath part B223), the lower edge B2232a of the outer side part B2232 of the upper sheath part B223 is connected to the side fence part B221 through two connection structures B40. The remaining parts (i.e., the parts corresponding to the handrail seat B182 and the parts corresponding to the top corner member B16) are not connected to the side fence part B221. In other words, a first opening B42 is formed between the two connection structures B40, and a second opening B44 is formed at the position corresponding to the top corner member B16, as shown in FIG. 23. In this way, as shown in FIG. 25, in the folding process of the child crib B1, the handrail seat B182 moves downward relative to the side wall seat cloth B22 and is exposed from the first opening B42 mentioned above. That is, the first opening B42 allows the handrail seat B182 to move downward relative to the upper sheath part B223 in the folding process of the child crib B1, making the folding of the child crib B1 smoother. The second opening B44 is provided for the convenience of mounting the upright post B12 and the handrail assembly B18 on the seat cloth B20. In addition, for aesthetic consideration, preferably, when the child crib B1 is in the unfolded state, the upper sheath part B223 completely shields the handrail seat B182, that is, the lower edge B2232a of the outer side part B2232 of the upper sheath part B223 (shown in FIG. 24) extends downward beyond the lower edge B182a of the handrail seat B182 (shown in FIG. 21). In some embodiments, the connection structure B40 is a sewing line, but it can also be other connection structures, such as Velcro, etc.

However, due to the provision of the upper sheath part B223, in the folding of the child crib B1, as the handrail seat B182 moves downward, the lower edge B2231a of the inner side B2231 (shown in FIG. 23) of the upper sheath part B223 is prone to catching or enveloping the lower edge B182a (shown in FIG. 21) of the handrail seat B182. This can hinder the downward movement of the handrail seat B182, to impede the folding of the handrail assembly B18 and consequently prevent the crib frame B10 from folding. In particular, in some embodiments, the lower edge B2231a of the inner side part B2231 of the upper sheath part B223 (i.e., the side facing the interior of the child crib B1) may also be provided with an engaging member B50 (shown in FIG. 23), such as a zipper, to connect other accessory devices (e.g., a hammock) of the child crib B1. The presence of this engaging member B50 makes it even more likely for the lower edge B2231a of the inner side part of the upper sheath part B223 to be caught with the lower edge B182a of the handrail seat B182.

Therefore, according to one embodiment of the present disclosure, the child crib B1 of the present disclosure further includes an anti-pinch device B30, which is a guiding element B32 in this embodiment. Specifically, as shown in FIGS. 23 to 27, which are schematic views of the child crib B1 provided with the guiding element B32 according to the present disclosure, since the upper sheath part B223 is formed by folding the side wall seat cloth B22 after passing across the handrail assembly B18 and the top corner member B16, the upper sheath part B223 is actually a double-layer structure. According to this embodiment, the guiding element B32 may be located inside the double-layer structure of the upper sheath part B223 and connected to the upper sheath part B223 at a position corresponding to the inner side of the handrail seat B182, that is, the guiding element B32 is connected to the inner side part of the upper sheath part B223. The connection method may be sewing, but not limited thereto. Preferably, the guiding element B32 is sewn at both ends in a transverse direction to the upper sheath part B223, specifically, the guiding element B32 is fully sewn to the upper sheath part B223 in a height direction at both ends in the transverse direction. Preferably, the guiding element B32 has a certain degree of elasticity, for example, it is made of a PE plate. In the folding process of the child crib B1, the two handrail tubes B181 of each side of the handrail assembly B18 are pivoted relative to each other in opposite directions, causing the corresponding upper sheath part B223 to be wrinkled. The guiding element B32, which is fixed at both ends inside the upper sheath part B223, may be deformed and arched inward to some extent, thereby pushing the inner side part of the upper sheath part B223 outward relative to the handrail seat B182 into the interior of the child crib B1. This prevents the lower edge of the upper sheath part B223 from obstructing the downward movement of the handrail seat B182, and make the folding of the child crib B1 smoother.

FIG. 24 shows a partial view of an inside of the child crib B1 corresponding to the position of the handrail seat B182, where the child crib B1 is in the process of being folded. FIG. 25 shows a partial view of an outside of the child crib B1 corresponding to the position of the handrail seat B182, where the child crib B1 is in a fully folded state or close to a fully folded state. As shown in FIGS. 24 and 25, in the folding of the child crib B1, as the handrail seat B182 moves downward relative to the handrail tube B181, due to the provision of the guiding element B32, the guiding element B32 continuously pushes and expands the upper sheath part B223 during the folding process. Therefore, it can prevent the lower edge B2231a of the inner side part B2231 of the upper sheath part B223 from catching on the lower edge B182a of the handrail seat B182, to allow the handrail seat B182 to smoothly slide out from the first opening B42 at the lower edge B2232a of the outer side part B2232 of the upper sheath part B223. The right side of FIG. 24 shows the guiding element B32 when the child crib B1 is not folded, which has an overall rectangular plate structure. The left side of FIG. 24 shows the guiding element B32 during the folding of the child crib B1 in a dashed line. In the folding process of the child crib B1, the guiding element B32 is also gradually deformed and arched inward. In addition, as shown in FIG. 25, the handrail seat B182 may also be encased with a fabric cover B182b.

In addition, as shown in FIG. 26A, the end of the upper sheath part B223 after being folded is not sewn to the side wall seat cloth B22 at the position corresponding to the top corner member B16. Therefore, in the folding of the child crib B1, the unsewn part forms a second opening B44, which facilitates the assembly operation of the crib frame B10 and the seat part B20. Moreover, as shown in FIG. 26A, a connecting member B60, such as a connecting hook, is provided on the upper sheath part B223 at the position corresponding to the top corner member B16. This connecting member B60 is configured to be connected with the top corner member B16 to prevent the upper sheath part B223 from accidentally disengaging from the top corner member B16 in the folding and unfolding process.

According to another embodiment, as shown in FIG. 26B, a shielding plate B70 may be provided at the aforementioned location of the opening. The shielding plate B70 may be a rectangular fabric material. According to the illustrated embodiment, both sides of the lower edge of the shielding plate (except for the part through which the upright post passes) and the two side edges are fixedly connected to the seat cloth B20. The fixing method may be sewing, but not limited thereto. The upper edge of the shielding plate B70 is not fixed. Referring to FIG. 22, in order to make the shielding plate B70 fit over the top corner member B16, an opening B72 through which the upright post B12 may pass is provided on the lower edge of the shielding plate B70 that is fixed to the seat part B22. In addition, in order to minimize the exposure of the top corner member B16, the two sides of the lower edge of the shielding plate B70 are fixedly connected to the seat part B22, to make the size of the opening on the lower edge of the shielding plate B70 roughly equivalent to a radial size of the upright post, that is, the size of the opening is slightly larger than the radial size of the upright post. FIG. 22 shows a schematic view of the shielding plate B70 in the unfolded state of the child crib B1. Since the shielding plate B70 is located inside the upper sheath part B223, which is schematically shown with dashed lines. As shown in FIG. 22, the two sides of the lower edge of the shielding plate B70 and its two side edges are sewn to the seat cloth B20. FIG. 22 also shows the sewing line B71 and the opening B72 through which the upright post B12 passes. Specifically, the shielding plate B70 is located inside the upper sheath part B223, at a position corresponding to the opening B72. The provision of the shielding plate B70 can prevent fingers from accidentally extending into the opening below the top corner member B16, thereby enhancing the safety of the folding operation of the child crib B1.

FIG. 27 shows another embodiment structure of the guiding element B32 provided in the child crib according to the present disclosure. According to this embodiment, the guiding element B32 is fixedly connected to the inner side of the handrail seat B182 or is integrally formed with the handrail seat B182 on its inner side. The lower edge of the guiding element B32 extends downward beyond the lower edge of the upper sheath part B223, that is, the lower edge of the guiding element B32 is exposed from the opening of the upper sheath part B223. This prevents the lower edge of the handrail seat B182 from being caught or enveloped by the lower edge of the upper sheath part B223, to make the folding of the child crib B1 smoother. The remaining configurations are the same as those in the embodiments shown in FIGS. 23 to 26B.

As described above, the guiding element B32 is provided on the inner side of the handrail seat B182 (i.e., the side facing a center of the child crib B1), or is fixed inside the upper sheath part B223 corresponding to the inner side of the handrail seat B182, but not limited thereto. Considering that the lower edge B2232a of the outer side part B2232 of the upper sheath part B223 also has the risk of being caught by the lower edge B182a of the handrail seat, the guiding element B32 may also be provided on (or corresponding to) the outer side of the handrail seat B182, or the guiding element B32 may be provided on (or corresponding to) both the inner and outer sides of the handrail seat B182 at the same time.

In some embodiments, referring to FIGS. 28 and 29, the child crib B1 according to the present disclosure may also be provided with an encasing element B34. The encasing element B34 is located inside the upper sheath part B223 and encases the handrail seat B182. As shown in FIGS. 28 and 29, the encasing element B34 is generally in the form of a sleeve structure, with openings at both ends for the handrail tube to pass through. This sleeve structure is larger in the middle and smaller at both ends, which can prevent the encasing element B34 from sliding relative to the handrail seat B182. The ends of the sleeve structure are sewn to the side of the upper sheath part B223 close to the handrail tube, to encase the handrail seat B182 and the handrail tube B181. This prevents the risk of pinching a user's fingers during the folding of the child crib B1 due to the exposure of the handrail seat B182 outside the upper sheath part B223 during downward movement. The sleeve structure may be elastic to facilitate the folding of the handrail seat B182 and the handrail tube B181, to avoid the sleeve structure from pulling the handrail seat B182 and the handrail tube B181 and affecting the folding of the entire crib frame. As shown in FIG. 29, an openable structure B341, such as Velcro, buttons, hooks, etc., may be provided at either end of the encasing element B34. In this way, when it is necessary to mount the sleeve structure, the Velcro, buttons, hooks, etc. may be opened first, and then the sleeve structure may be fitted over the handrail tube B181 from this end and moved to the handrail seat B182. After that, the Velcro, buttons, hooks, etc. are combined to complete the assembly of the sleeve structure.

According to this embodiment, the encasing element B34 completely encases the ends of the two handrail tubes B181 and the handrail seat B182. During the folding of the crib frame B10, the encasing element B34 always completely encases the handrail seat B182 and the connection between the handrail seat B182 and the handrail tube B181. This effectively prevents the risk of pinching the user's fingers during the folding process when the user's hand protrudes into the connection between the two, in order to make the use safer.
