DESCRIPTION

Foldable sleeping basket

Technical field

This application pertains to the technical field of folding baskets, and in particular refers to a folding sleeping basket.

Background of the technique

The bassinet (carrying basket) attached to a baby stroller makes it convenient for people to take the baby out. For greater travel convenience, most modern baby strollers and bassinets are designed to be foldable, making them easier to transport or carry outdoors. Conventional baby bassinets typically fold up and down to flatten, which facilitates packing or loading into a vehicle for transport. However, this folding method only changes the dimensions from top to bottom; it doesn't change the length from left to right. Even when folded, a conventional bassinet remains quite long and takes up a lot of space, making it difficult to carry or transport later. Furthermore, the folding mechanism is controlled by buttons on two sides, which is inconvenient to operate.

Therefore, the problem that an expert in the field must urgently solve is how to change the existing up-and-down folding procedure and provide a foldable sleeping basket that has a new folding procedure, easy operation, and a small footprint after folding.

Compendium

In view of this, the present application provides a collapsible sleeping basket, which changes the traditional up-and-down folding procedure of the sleeping basket and uses a left-to-right folding procedure to reduce the overall length and dimensions of the folded sleeping basket, making it easier to pack it away or transport it outdoors.

In order to achieve the aforementioned objective, the present application adopts the following technical solution: a foldable sleeping basket, which includes:

two groups of support rod seats, arranged at an interval, wherein a plurality of transverse support rods are fixedly connected between the two groups of support rod seats, and two end sides of the two groups of support rod seats are each hinged to a bent lower rod;

inclined support rods, grouped in pairs and symmetrically hinged to the support rod seats, wherein a connecting rod is hinged between each inclined support rod and the corresponding lower rod on the same end side of the support rod seat, and the support rod seat and the inclined support rod, the connecting rod and the lower rod on the same end side form a first four-rod connecting mechanism;

two groups of surrounding rods, both rods being bent, wherein the two groups of surrounding rods are in one-to-one correspondence with and arranged above the two lower groups of rods, the ends of the two groups of surrounding rods being hinged, the upper ends of the inclined support rods being hinged to the surrounding rods on the corresponding sides, the two groups of inclined support rods in the same support rod seat and the surrounding rods forming a second four-rod connecting mechanism, and the second four-rod connecting mechanism being a control end and configured to change in an interconnected manner the deformation state of the first four-rod connecting mechanism; and

a handle, articulated at the joints of the two surrounding rod groups.

The technical effects of this application include the following: the product performs the folding deformation of the sleeping basket based on the cooperation of two basic four-rod articulation mechanisms. The second four-rod connecting mechanism controls the folding and unfolding of the first four-rod connecting mechanism, and the inclined support rods provide a deformation base for folding the second four-rod connecting mechanism on two sides. The product allows for changing the overall length of the sleeping basket, facilitating subsequent packing or transport. It should be noted that this product is a connecting mechanism, and the deformation of the second four-rod connecting mechanism controls the deformation of the first four-rod connecting mechanism in an interlocking manner. Therefore, when in use, it is only necessary to monitor the deformation state of the second four-rod connecting mechanism, allowing for convenient operation and use.

Preferably, the outer side of each support rod seat away from the cross support rods is hinged to an interface seat configured to connect a baby stroller frame, and the interface seat is configured to rotate a certain angle with respect to the support rod seat.

The resulting technical effect is that the interface seat can connect the bassinet to the stroller frame, facilitating its subsequent use. Meanwhile, the interface seat can rotate at a certain angle relative to the support rod seat, adjusting the bassinet's position on the stroller frame to meet the baby's varying needs.

Preferably, the support rod seat is provided with a vertical plate, and the hinge joints of the two groups of inclined support rods are located on the vertical plate.

The resulting technical effect is that the vertical plate serves as both the mounting base for the interface seat and the articulated base for the inclined support rods. Due to the design of the vertical plate, the support rod seat can also be used as a connecting rod, thus forming a first-of-its-kind deformable four-rod connection mechanism.

Preferably, the first four-rod connecting mechanism and the second four-rod connecting mechanism each have an extended and a folded state. In the extended state, the second four-rod connecting mechanism is a horizontally inverted triangle, and the deformation joint of the second four-rod connecting mechanism is located at the center of the base of the inverted triangle. In the folded state, the included angle of the two inclined support rods of the second four-rod connecting mechanism is reduced, and simultaneously, the first four-rod connecting mechanism retracts and deforms in an interlocking manner.

The resulting technical effect is that in the deployed state, the second four-rod connecting mechanism is a horizontally inverted triangle, with the deformation joint at the midpoint of the base, allowing the two lateral ends of the second four-rod connecting mechanism to fold upwards and be stored, completing the folding and storage on both sides, thus reducing the length of the sleeping basket after folding.

Preferably, the lower rods and surrounding rods are all U-shaped, and two ends of each lower rod are hinged respectively to the end sides of the two groups of support rod seats, and the close end sides of the two groups of surrounding rods are connected with hinge assemblies respectively, the hinge assemblies serve as the hinge joints of the two groups of surrounding rods and control the folding angles of the two groups of surrounding rods, the handle is a U-shaped member, and two ends of the handle are hinged respectively to the hinge assemblies on the corresponding sides.

The resulting technical effect is that the hinge assembly is the basis for controlling the deformation of the second four-rod connecting mechanism and the first four-rod connecting mechanism, and the arrangement of the hinge assemblies can adjust and control the folding angles of the two surrounding rods.

Preferably, one of the surrounding rods is a hollow rod, and a middle section of the surrounding rod is movably connected to an operating member. The operating member is connected to a pull cord. The pull cord passes through the hollow rod and is connected to hinge assemblies at two ends of the surrounding rods. Rotation of the operating member causes the pull cord to shift and change the rotation lock states of the hinge assemblies.

The resulting technical effect is that the deformation state of the entire sleeping basket is controlled by an operating member, allowing for convenient operation and easy control.

Preferably, the hinge assembly includes a first hinge seat, a second hinge seat, a gear plate, and a swivel plate that are coaxially connected, wherein the first hinge seat and the second hinge seat are respectively fixed to one end of the two surrounding rod groups, one side, close to each other, of the first hinge seat and the second hinge seat are provided with a mounting groove, and the groove walls corresponding to the mounting grooves of the first hinge seat and the second hinge seat are provided with a tooth structure, the gear plate is arranged close to and within the mounting groove of the second hinge seat, a spring is arranged between the gear plate and the bottom of the mounting groove of the second hinge seat, and the gear plate can slide axially in the mounting groove of the first hinge seat; and

When the gear plate is engaged with the tooth structures of the first and second hinge seats, the rotation angles of the first and second hinge seats are locked. When the gear plate is positioned in the mounting groove of the second hinge seat, the first and second hinge seats rotate relative to each other. The swivel plate is rotatably positioned in the mounting groove of the first hinge seat and connected to the pull cord. The lower wall of the mounting groove of the first hinge seat is fitted with a wedge block configured to be driven by the rotation of the swivel plate, causing it to be axially displaced. The axial movement of the swivel plate pushes the gear plate to be axially displaced.

The resulting technical effect is that the rotation of the hinge assemblies can change the folding angles of the two surrounding rods, and the locking and adjustment of the rotation angles of the two hinge seats can be achieved according to the cooperation of the swivel plate and the gear plate.

Preferably, the first hinge seat is provided with a circumferentially annular wavy groove structure, each end of the handle is provided with a connecting seat, the connecting seat is rotatably connected to the outer side of the corresponding first hinge seat, and the connecting seat is provided with a damping protrusion that matches the wavy groove structure.

The resulting technical effect is that the rotation position and angle of the handle with respect to the two surrounding rods can be fixed, making it easier to use.

The technical solutions in the embodiments of this application will be clearly and completely described below, along with the drawings in the application. The embodiments described herein are only some, not all, of those in this application. Based on the embodiments in this application, all other embodiments obtained by a person skilled in the art without paying for creative work fall within the scope of protection of this application.

With reference to FIGS. 1-8 of this application, a collapsible sleeping basket according to embodiments of this application includes:

two groups of support rod seats 1 arranged at an interval, wherein two transverse support rods 2 are fixedly connected between the two groups of support rod seats 1, and the two end sides of the two groups of support rod seats 1 are each hinged to a bent lower rod 3;

the inclined support rods 4 grouped in pairs and symmetrically hinged to the support rod seats 1, wherein a connecting rod is hinged between each inclined support rod 4 and the corresponding lower rod 3 on the same end side of the support rod seat 1, and the support rod seat 1 and the inclined support rod 4, the connecting rod and the lower rod 3 on the same end side form a first four-rod connecting mechanism;

two groups of surrounding rods 5, both rods being bent, wherein the two groups of surrounding rods 5 are in one-to-one correspondence with and arranged above the two lower groups of rods 3, the ends of the two groups of surrounding rods 5 being hinged, the upper ends of the inclined support rods 4 being hinged to the surrounding rods 5 on the corresponding sides, the two groups of inclined support rods 4 on the same support rod seat 1 and the surrounding rods 5 forming a second four-rod connecting mechanism, and the second four-rod connecting mechanism is a control end and changes in an interconnected manner the deformation state of the first four-rod connecting mechanism; and

a handle 6, wherein the handle 6 is hinged at the joints of the two surrounding rod groups 5.

This product includes 4 inclined support rods and 4 connecting rods.

In other embodiments, the outer side of the support rod seat 1, furthest from the transverse support rods 2, is articulated to an interface seat 7 for connecting to a baby stroller frame. The interface seat 7 can rotate a certain angle relative to the support rod seat 1 to change the position of the sleeping basket on the stroller frame.

In other embodiments, the support rod seat 1 is provided with a vertical plate 11, and the hinge joints of the two groups of inclined support rods 4 are located on the vertical plate 11. It can be understood that the support rod seat with the vertical plate is used equivalently as a connecting rod in the first four-rod connecting mechanism.

In some other specific embodiments, the first four-rod connecting mechanism and the second four-rod connecting mechanism each have an extended and a folded state. In the extended state, the second four-rod connecting mechanism is a horizontally inverted triangle, and the deformation joint of the second four-rod connecting mechanism is located at the center of the base of the inverted triangle, allowing it to be folded from left to right and stored to reduce the length of the sleeping basket. In the folded state, the included angle of the two inclined support rods of the second four-rod connecting mechanism is reduced, and simultaneously, the first four-rod connecting mechanism retracts and deforms in an interlocking manner.

In some other embodiments, the lower rods 3 and the surrounding rods 5 are all U-shaped. The two ends of the lower rod 3 are hinged to the end sides of the two support rod seat groups 1. The close ends of the two surrounding rod groups 5 are connected to hinge assemblies 8. That is, there are two sets of hinge assemblies. The hinge assemblies 8 serve as hinge joints for the two surrounding rod groups 5 and control their folding angles. The handle 6 is a U-shaped member, and its two ends are hinged to the corresponding hinge assemblies 8.

In some other specific embodiments, one of the surrounding rods 5 is a hollow rod, and the mid-section of the surrounding rod is movably connected to an operating member 9. The operating member 9 is connected by a tension cord. The tension cord passes through the hollow rod and is connected to hinge assemblies 8 at the two ends of the surrounding rod 5. Rotation of the operating member 9 causes the tension cord to shift and change the rotational locking states of the hinge assemblies 8.

Specifically, the hinge assembly 8 includes a first hinge seat 81 (on the relatively outer side), a second hinge seat 82 (on the relatively inner side), a gear plate 83, and a swivel plate 84, all of which are coaxially connected. The first hinge seat 81 and the second hinge seat 82 are fixedly connected to one end of the two surrounding rod groups 5, respectively. Each side of the first hinge seat 81 and the second hinge seat 82, which are close to each other, is provided with a mounting groove. The groove walls corresponding to the mounting grooves of the first hinge seat 81 and the second hinge seat 82 are each provided with a tooth structure 85; the gear plate 83 is arranged close to and within the mounting groove of the second hinge seat 82; a spring is arranged between the gear plate and the bottom of the groove of the mounting groove of the second hinge seat 82; and the gear plate 83 can slide axially in the mounting groove of the first hinge seat 81; and

When the gear plate 83 is engaged with the tooth structures on the first hinge seat 81 and the second hinge seat 82, the rotation angles of the first hinge seat 81 and the second hinge seat 82 are locked. When the gear plate 83 is placed in the mounting groove of the second hinge seat 82, the first hinge seat 81 and the second hinge seat 82 rotate relative to each other, and the swivel plate 84 is rotatably positioned in the mounting groove of the first hinge seat 81 and connected to the pull cord. A wedge block 86, to be driven by the rotation of the axially displaced swivel plate, is provided on the lower wall of the mounting groove of the first hinge seat 81. A wedge-shaped groove is provided in a portion of the swivel plate 84 corresponding to the wedge block, and the axial movement of the swivel plate 84 pushes the gear plate 83 to axially displace it.

It should be noted that due to the spring action, under normal circumstances, the gear plate 83 meshes with the tooth structures 85 in the first hinge seat 81 and the second hinge seat 82 simultaneously. Only when the operating member 9 rotates the swivel plate 84 and the gear plate 83 is pressed into the second hinge seat 82 can the two hinge seats rotate relative to each other.

In other embodiments, the first hinge seat 81 is provided with a circumferentially annular wavy groove structure 811. Each end of the handle 6 is provided with a connecting seat 10. The connecting seat 10 is rotatably connected to the outer side of the first hinge seat 81, and the connecting seat 10 is provided with a damping protrusion 101 that matches the wavy groove structure.

It can be understood that, based on the cooperation between the wavy groove structure and the damping protrusion, the rotation angle of the handle can be relatively fixed (not easily rotated), making it easier for the user to use it later.

Regarding the device and the procedure for use described in the embodiments, since they correspond to the procedure described in the embodiments, the description is relatively simple, and the relevant parts can refer to the description of the part of the procedure.

The foregoing description of the embodiments described herein enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined in this invention can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application shall not be limited to the embodiments shown herein, but shall be adapted to the broader scope consistent with the principles and novel features described herein.
