In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

Referring to fig. 1 to 5, the present application provides a carrying device 1000, which has an accommodating space 190 with an open top, wherein the accommodating space 190 is different according to requirements, for example, the accommodating space 190 accommodates children, the carrying device 1000 is a child basket, or the accommodating space 190 accommodates pets, and the carrying device 1000 is a pet basket.

The carrying device 1000 further comprises a supporting skeleton 100, and two adapters 180 arranged on both sides of the supporting skeleton 100, respectively. In the drawings, the supporting frame 100 has a length direction in which X is located and a width direction in which Y is located, two adapters 180 are disposed at both sides of the supporting frame 100 in the width direction, the adapters 180 are used for connecting the supporting device 4000, and the adapters 180 may be fixedly connected to the supporting device 4000 or detachably connected. Wherein, the supporting framework 100 rotates relative to the adapter 180 and has a storage state (for example, shown in fig. 3) close to the supporting device 4000, and a unfolded use state (for example, shown in fig. 2) far away from the supporting device 4000.

The support frame 100 includes a top frame 110, a bottom frame 120, side frames 140, and linkages 148. The top frame 110 defines an opening at the top of the receiving space 190 for children or articles to enter and exit the receiving space 190, and the structure of the top frame 110 includes, but is not limited to, a closed ring frame. The bottom frame 120 provides a bottom support for the receiving space 190 and is disposed opposite to the top frame 110 up and down, wherein the adapter 180 is rotatably connected to the bottom frame 120 or the top frame 110. The side frames 140 are two and arranged in pairs in the width direction, the side frames 140 are disposed between the top frame 110 and the bottom frame 120 in a foldable manner, when the side frames 140 are folded, the top frame 110 and the bottom frame 120 are closed, and when the side frames 140 are unfolded, the top frame 110 and the bottom frame 120 are separated to form the receiving space 190, and in a preferred embodiment, the top frame 110 and the bottom frame 120 are closed and separated in alignment.

The link 148 is disposed between the side frame 140 and the corresponding adapter 180, and when the support frame 100 rotates relative to the adapter 180, the link 148 allows the side frame 140 to be synchronously switched between the folded state and the unfolded state. Wherein rotation of the support frame 100 relative to the adapter 180 occurs simultaneously with folding and unfolding of the side frames 140, and there is no strict active or passive relationship between the two. That is, for example, folding and unfolding of the side frames 140 may be performed to drive rotation of the support frame 100 relative to the adapter 180, and for example, rotation of the support frame 100 relative to the adapter 180 may be performed to drive folding and unfolding of the side frames 140.

The following description is made in connection with a method of using one of the carrying devices:

Referring to fig. 2 to 4, in fig. 2, the support frame 100 is in a unfolded use state, the bottom frame 120 is in a horizontal state, and the adapter 180 is rotatably connected to the bottom frame 120. The folding process includes driving the support frame 100 to rotate relative to the adapter 180 in a second direction indicated by the arrow while the support frame 100 is folded, and eventually the bottom frame 120 is tilted relative to a horizontal position, in which the support frame 100 is drawn closer to the support device 4000 (shown in phantom). The external force applied to the supporting frame 100 may be manually applied, or provided when the top frame 110 falls under the action of gravity;

The deployment process includes driving the support frame 100 to rotate in a first direction (opposite the second direction) relative to the adapter 180 while the support frame 100 is deployed until the bottom frame 120 is in a horizontal state and the support frame 100 is in a deployed state. Wherein the external force applied to the supporting frame 100 is artificially provided to move upward away from the bottom frame 120 against the gravity applied to the top frame 110.

In another embodiment, the adapter 180 is rotatably coupled to the top frame 110. Folding and unfolding processes refer to the previous embodiments, except that during folding, it is necessary to manually apply rotation of the support frame 100 relative to the adapter 180 so that the bottom frame 120 moves up against gravity to close to the top frame 110, and conversely, during unfolding, the external force required to rotate the support frame 100 may be provided entirely by the bottom frame 120 falling under the force of gravity, or by a person, or both.

The bearing device is connected to the supporting device, the supporting framework is folded and unfolded, the supporting framework and the supporting framework rotate relative to the adapter at the same time and are related to each other, for example, when the bearing device is stored, the supporting framework is rotated along the second direction, the supporting framework is folded at the same time, and when the bearing device is unfolded and used, the supporting framework is rotated along the first direction, and the bearing device is unfolded at the same time.

For other structures of the carrying device 1000, in an embodiment, the support frame 100 is in a horizontal state in the unfolded state, and the bottom frame 120 is in a horizontal state. In the folded state of the support frame 100, the bottom frame 120 is inclined with respect to the horizontal state, and in particular, the bottom frame 120 is inclined to be close to the support device 4000, so as to be convenient for storage.

Referring to fig. 6, a first hinge point 181 is formed between the adapter 180 and the bottom frame 120 or the top frame 110, a second hinge point 182 is formed between the adapter 180 and the link 148, a third hinge point 183 is formed between the link 148 and the side frame 140, a fourth hinge point 184 is formed between the side frame 140 and the bottom frame 120 or the top frame 110, and sequential connection lines of the first hinge point 181, the second hinge point 182, the third hinge point 183 and the fourth hinge point 184 form a foldable four-bar mechanism.

In one embodiment, the carrier 1000 includes a locking device that locks the support frame 100 such that the support frame 100 remains in the deployed state. When the carrying device 1000 is kept in the unfolded state, the supporting framework 100 is relatively fixed relative to the adapter 180, that is, the carrying device 1000 is kept in the unfolded use state, and accordingly, the unlocking operation and the unlocking piece only need to be specific to the locking device, so that the cost is saved. Wherein, the locking device can adopt the prior art or the following embodiments.

Referring to fig. 1, 6 and 7, in one embodiment, the support frame 100 further includes a connection base 130 and a driving member connecting the two side frames 140, the connection base 130 being for connecting the two side frames 140, and being slidably mounted on the bottom frame 120 and having a first position and a second position on a sliding path, the respective side frames being switched between a folded state and an unfolded state when the connection base 130 is slid between the two positions. The driving member is used for driving the connecting seat 130 to slide from the first position to the second position to unfold the side frame 140.

The structure of the side frame 140 includes, but is not limited to, the structure provided by the present application, and the side frame 140 includes a plurality of first side bars 141, and each first side bar 141 is inclined in the same direction, for example, an angle is formed between the top frame 110 and the bottom frame 120. For example, in the illustration, the top frame 110 and the bottom frame 120 are parallel to each other, and then the first side bars 141 are also parallel to each other, and the connection base 130 is connected to all the first side bars 141 to realize synchronous movement of the first side bars 141, so as to ensure that the side frames 140 on two sides can be folded or unfolded synchronously. Further, the side frame 140 further includes a second side bar 142, one end of the second side bar 142 is hinged to the first side bar 141, the other end is hinged to the bottom frame 120, and the inclination directions of the second side bar 142 and the first side bar 141 are opposite, so as to improve the structural stability of the support frame 100 in the unfolded state. Wherein, one end of the linkage 148 is hinged to the second side bar 142, and the other end is hinged to the adapter 180, and the linkage 148 is a rod.

In actual operation, when the supporting frame 100 is in the folded state, the operation driving member drives the connecting seat 130 to move along the third direction, the upper portion of the first side bar 141 moves upwards to drive the top frame 110 away from the bottom frame 120 until the supporting frame 100 is in the unfolded state, and when the supporting frame 100 is folded, the top frame 110 is pressed downwards to enable the connecting seat 130 to slide along the fourth direction until the supporting frame 100 is in the folded state. Compared with the prior art, the unfolding operation is more convenient.

Referring to fig. 8 with emphasis, the carrying device 1000 further includes a flexible crotch 200 connected between the top frame 110 and the bottom frame 120 and wrapping the side frames 140, and in the unfolded state, the flexible crotch 200 pulls the top frame 110 and the bottom frame 120 so that the supporting framework 100 is unfolded to the maximum height, thereby indirectly limiting the connection seat 130 to continue moving along the pulling direction.

The connection base 130 may be a frame formed by a cross bar or a plurality of rods, or a member slidably sleeved on the bottom frame, etc. For example, as shown in fig. 7, in one embodiment, the connecting seat 130 is a frame structure, and includes two cross bars 131 corresponding to a pair of first side bars 141, and at least one longitudinal bar 132 connected between the two cross bars 131, two ends of the cross bars 131 are slidably engaged with the bottom frame 120, and the two side frames 140 are hinged to the connecting seat 130, for example, one pair of first side bars 141 symmetrically arranged in the two side frames 140 is hinged to one of the cross bars 131, and the other pair of first side bars 141 is hinged to the other cross bar 131. For another example, the connection base 130 includes a slider slidably engaged with the bottom frame 120 and a cross member connecting the two sliders, and the first side bar 141 on the same side is hinged to the slider.

Further, the carrying device 1000 further comprises a locking device 160 for locking the supporting framework 100 in the unfolded state, wherein the locking can be arranged between the connection seat 130 and the bottom frame 120, i.e. locking the connection seat 130.

In some embodiments, the locking device 160 is locked by limiting the movement of the driving member, and it should be emphasized that the object of the locking device 160 is the driving member. Specifically, the driving member is a flexible member 150, the flexible member 150 is used to extend the supporting frame 100 by pulling the connecting seat 130, and the flexible member 150 is a belt or a wire or a combination of two shapes, such as a nylon webbing or a steel wire, or a combination of two types, etc. When the carrying device of the present application is unfolded, the locking device 160 acts on the corresponding position of the flexible member 150 to keep the supporting framework 100 in the unfolded state all the time, so as to avoid the safety accident caused by folding due to the locked out position.

The flexible member 150 has a fixed end 151 and an operating end 152, the operating end 152 is exposed outside the supporting frame 100, and the length of the operating end 152 exposed outside the supporting frame 100 is increased during the stretching operation. The connection relationship between the flexible member 150 and the connection base 130 adopts at least one of the following:

a) The fixed end 151 is fixedly connected with the bottom frame 120, the operation end 152 bypasses the connecting seat 130 and is located at the same side of the connecting seat 130 as the fixed end 151 (for example, fig. 6), preferably, the operation end 152 bypasses one of the cross bars 131, and the outer contour of the contact part between the cross bar 131 and the flexible member 150 is circular, for example, a circular bar, so as to facilitate the movement of the flexible member 150;

b) The fixed end 151 is fixedly connected to the connection base 130 (e.g., fig. 9).

Wherein the locking device 160 allows the flexible member 150 to move in a pulling direction (corresponding to the movement of the connecting seat in the third direction), and prevents the flexible member 150 from moving in the opposite direction (i.e., the retraction direction described below) (corresponding to the movement of the connecting seat in the fourth direction). The lock device 160 includes:

a locked state allowing the flexible member 150 to move unidirectionally in the pulling direction, i.e., restricting the flexible member 150 from moving in the retracting direction;

the unlocked state allows the flexible member 150 to move bi-directionally.

As shown in fig. 10 to 12, the locking device 160 includes a lock base 161, a lock member 162, and an elastic member acting on the lock member 162, a channel 163 is formed between the lock member 162 and the lock base 161 for the flexible member 150 to pass through, and the lock member 162 and the lock base 161 hold the flexible member 150 in a locked state, and in this state, the lock member 162 is only rotatable in one direction. Specifically, the locking member 162 is rotatably mounted on the locking seat 161 with an elastic member (e.g., torsion spring) disposed therebetween, and the locking member 162 has locking teeth 164, the locking teeth 164 and the locking seat 161 to provide a clamping force.

The locking member 162 rotates relative to the locking base 161 and has an unlocking direction (shown by an arrow in fig. 12) and a locking direction, and when the operating end 152 of the flexible member 150 moves in the pulling direction, a force for rotating the locking member 162 in the unlocking direction is applied, so that a clamping force of the locking member 162 and the locking base 161 on the flexible member 150 is reduced or even eliminated, and when the operating end 152 of the flexible member 150 moves in the retracting direction, a force for rotating the locking member in the locking direction is applied, so that the clamping force of the locking member 162 and the locking base 161 on the flexible member 150 is gradually increased, similar to self-locking. This structure realizes the aforementioned operation that the flexible member 150 can move unidirectionally, and can allow the locking device 160 to act on any position of the flexible member 150, ensuring that the supporting frame is in the unfolded state, thereby disregarding the influence of errors caused by processing and assembly. Before the carrying device is folded, after the lock 162 is manually pressed to unlock the carrying device, the folding operation is performed by pressing the top frame 110.

Referring to fig. 2 to fig. 4, in the process of unfolding the support frame 100 from fig. 4 to fig. 2, specifically, the adapter 180 is rotatably connected to two sides of the bottom frame 120, and when the support frame is unfolded for use, the flexible member 150 is pulled, so as to drive the support frame 100 to rotate along the first direction relative to the adapter 180 until the bottom frame 120 is in a horizontal state. Wherein, the direction of pulling the flexible member 150 is the same as the direction of the first direction in the horizontal direction.

Wherein the locking device 160 is provided at an edge of the bottom frame 120, for example, at one side in the X direction in the drawing. In an embodiment, the lock member 162 is limited to further rotate in the locking direction in the locked state, where the lock base 161 is provided with a limiting portion, such as a boss on the lock base 161, that abuts against the lock member 162. In an embodiment, a connection structure for fixing the flexible member 150 is disposed between the flexible member 150 and the flexible crotch 200, and the connection structure is, for example, a magic buckle disposed between the flexible member 150 and the flexible crotch 200, so as to prevent the portion of the flexible member 150 exposed outside the flexible crotch 200 from shaking randomly.

Referring to fig. 13 to 15, the present application further provides a child carrier 5000, which includes a supporting device 4000 and a carrying device 1000, wherein the carrying device 1000 is connected to the supporting device 4000 through an adapter 180.
