Description

A type of children's sleeping basket Technical Field

[0001] This invention relates to a children's sleeping basket. Background Technology

[0002] Existing child bassinets include a bassinet frame, a cloth cover for the bassinet frame, and a handle installed on the frame of the bassinet frame. In order to facilitate the assembly and disassembly of the child bassinet and child equipment (such as a stroller frame), existing stroller bassinets are often detachably installed by interlocking a mounting bracket on the bassinet frame with a fixing bracket on the child equipment (such as a stroller frame).

[0003] For ease of carrying and transportation, baby bassinets are typically designed with a foldable structure. However, current foldable baby bassinets have complex structures and are cumbersome to fold and unfold, making them inconvenient to use. Furthermore, most existing baby bassinets fold vertically, meaning their length cannot be shortened. This means that even when folded, the bassinets still take up considerable space, making them difficult to carry and store.

[0004] Summary of the Invention

[0005] The purpose of this invention is to provide a children's sleeping basket that has a novel structure, is easy to operate, and has a compact structure and small size when folded.

[0006] The technical solution of the present invention is: a child's bassinet, comprising a bassinet frame having an unfolded state and a folded state, and a handle provided on the bassinet frame. The bassinet frame includes a two-section upper frame assembly that can be folded upwards, a two-section lower frame assembly located below the upper frame assembly and also folded upwards, a two-section V-shaped support frame assembly rotatably installed between the upper and lower frame assemblies and folded up, which drives the lower frame assembly to fold upwards or unfold when the upper frame assembly is folded upwards, and a mounting seat for detachable assembly and installation with other children's products and mounted on the lower frame assembly; a locking mechanism is provided at the folding joint of the upper frame assembly to lock it in place when unfolded.

[0007] When the child bassinet is unfolded, the upper frame assembly and the lower frame assembly are unfolded and in a flat state, and the support frame assembly is unfolded into a V shape and supported between the upper frame assembly and the lower frame assembly. At this time, the locking mechanism locks the upper frame assembly in place, thereby keeping the entire child bassinet in the unfolded state.

[0008] When the child bassinet is folded, the locking mechanism is released, and the upper frame assembly is folded upwards and retracted. The lower frame assembly is then folded upwards and retracted in conjunction with the support frame assembly, thus completing the folding and retraction of the entire child bassinet.

[0009] As a preferred technical solution of this application, the upper frame assembly includes a first upper frame and a second upper frame arranged on the left and right sides and rotatably connected, and the locking mechanism is disposed at the rotatable connection between the first upper frame and the second upper frame.

[0010] The lower frame assembly includes a first lower frame and a second lower frame arranged on the left and right sides and rotatably connected. The mounting base is disposed at the rotatable connection between the first upper frame and the second upper frame, and the three are coaxially connected.

[0011] The support frame assembly includes a first support frame and a second support frame arranged on the left and right sides and rotatably connected at their lower ends. The upper end of the first support frame is rotatably connected to the first upper frame and the lower part is rotatably connected to the first lower frame. The upper end of the second support frame is rotatably connected to the second upper frame and the lower part is rotatably connected to the second lower frame.

[0012] The first upper frame and the second upper frame are U-shaped with their openings facing each other; the first lower frame and the second lower frame are U-shaped with their openings facing each other.

[0013] As a preferred technical solution of this application, the outer end of the first upper frame or the second upper frame is provided with an unlocking component for releasing the locking mechanism.

[0014] As a preferred technical solution of this application, the locking mechanism includes a first toothed groove formed at the inner end of the first upper frame, a second toothed groove formed at the inner end of the second upper frame and corresponding to the first toothed groove, a gear disposed between the first toothed groove and the second toothed groove and capable of simultaneously locking the first toothed groove and the second toothed groove, an unlocking block disposed between the gear and the first toothed groove and capable of radial movement, and a linkage disposed between the unlocking block and the gear. The linkage engages with the unlocking block on an inclined surface, and the unlocking block is connected to the unlocking assembly via a traction cable. When unlocking, the unlocking assembly drives the unlocking block to move radially and, through the inclined surface engagement, drives the linkage to move axially, thereby pushing the gear out of the first toothed groove and fully retracting into the second toothed groove to achieve unlocking.

[0015] As a preferred embodiment of this application, the linkage has a convex tooth extending axially towards the unlocking block. The side of the unlocking block has a guide portion that engages with the inclined surface of the convex tooth. When the unlocking assembly drives the unlocking block to move radially, the guide portion engages with the inclined surface of the convex tooth to drive the linkage to move axially. The linkage also has a protrusion extending axially towards the gear. A limiting groove is formed on the side of the gear corresponding to the protrusion, allowing the protrusion to abut and move. The engagement of the limiting groove and the protrusion prevents the linkage from rotating relative to the unlocking block when the linkage is lifted by the unlocking block (when the linkage has moved to its furthest axial position relative to the unlocking block and is about to disengage).

[0016] Compared with the prior art, this application has the following advantages:

[0017] 1. The upper frame assembly and the lower frame assembly in this invention are both two-section structures that can be folded upwards. The two-section V-shaped support frame assembly between them drives the lower frame assembly to fold upwards or unfold when the upper frame assembly is folded upwards. The overall structure is simple and novel. It can not only realize the folding of the bassinet in the longitudinal direction, but also the folding of the bassinet in the length direction, making the folded children's bassinet smaller in size and easier to carry and store.

[0018] 2. The locking mechanism of the present invention is set at the rotation connection of the upper frame assembly, and an unlocking component for releasing the locking mechanism is set at one end of the upper frame assembly. Therefore, when folding the child bassinet, one-handed one-button unlocking operation can be achieved without bending over, which is very convenient. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0037] In the description of this application and the claims, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates not less than two.

[0038] In the description of this application and the claims, the terms "connection," "installation," "fixation," and "reception," unless otherwise specified, should be interpreted broadly. For example, "connection" can mean a separate connection or an integral connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean a non-detachable connection or a detachable connection. As another example, "reception" does not necessarily mean complete containment; this concept also includes the containment of a portion that protrudes externally. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application based on the specific circumstances.

[0039] In the description of this application and the claims, if terms such as "above," "below," or "horizontal" indicate orientation or positional relationships based on the orientation or positional relationships shown in the drawings, they are only for the purpose of clearly and simply describing this application, and do not indicate or imply that the elements referred to must have a specific orientation or be constructed and operated in a specific orientation. These directional terms are relative concepts used for relative description and clarification, and may change accordingly depending on the orientation of the components in the drawings. For example, if the device in the drawings is flipped, an element described as "below" other elements will be positioned "above" other elements.

[0040] In the description of this application specification and claims, the term "if" is generally interchangeable with "when," "at," "in response to determination," or "in response to detection," depending on the context.

[0041] In the description of this application and the claims, if there is a "direction" of motion, including motion with a directional component, the term "in direction" is not necessarily understood as motion only in that one direction. Those skilled in the art can understand the specific meaning of the aforementioned terms in this application according to the specific circumstances.

[0042] As shown in Figures 1 to 8, a child's bassinet includes a bassinet frame having an unfolded state and a folded state, and a handle provided on the bassinet frame. The bassinet frame includes a two-section upper frame assembly 1 that can be folded upwards, a two-section lower frame assembly 2 located below the upper frame assembly 1 and folded upwards, a two-section V-shaped support frame assembly 3 that is rotatably installed between the upper frame assembly 1 and the lower frame assembly 2 and can be folded up and retracted, and drives the lower frame assembly 2 to fold up and retract or unfold when the upper frame assembly 1 is folded up or unfolded, and a mounting base 4 for detachable assembly and assembly with other children's products (such as stroller frames).

[0043] The upper frame assembly 1 includes a first upper frame 101 and a second upper frame 102 arranged rotatably on the left and right sides. A locking mechanism 5 is provided at the rotatable connection between the first upper frame 101 and the second upper frame 102 to enable them to be unfolded and locked. The first upper frame 101 and the second upper frame 102 are U-shaped with their openings facing each other, so as to form a conventional square upper frame assembly 1.

[0044] The lower frame assembly 2 includes a first lower frame 201 and a second lower frame 202 arranged rotatably on the left and right sides. The mounting base 4 is located at the rotatable connection between the first upper frame 201 and the second upper frame 202, and the three are coaxially connected. This design allows the bassinet to be folded even without detaching from other children's equipment (such as a stroller frame). The first lower frame 201 and the second lower frame 202 are U-shaped with openings facing each other, so as to form a conventional U-shaped lower frame assembly 2.

[0045] The support frame assembly 3 includes a first support frame 301 and a second support frame 302 arranged on the left and right sides and rotatably connected at their lower ends. The upper end of the first support frame 301 is rotatably connected to the first upper frame 101 and the lower part is rotatably connected to the first lower frame 201. The upper end of the second support frame 302 is rotatably connected to the second upper frame 102 and the lower part is rotatably connected to the second lower frame 202.

[0046] The rotation points at the lower ends of the first support frame 301 and the second support frame 302 are located below the rotation point between the mounting base 4, the first lower frame 201, and the second lower frame 202. The rotation points between the first support frame 301 and the first lower frame 201, and between the second support frame 302 and the second lower frame 202, are located on the left and right sides of the rotation point between the mounting base 4, the first lower frame 201, and the second lower frame 202, respectively.

[0047] In this embodiment, the outer end of the first upper frame 101 or the second upper frame 102 is provided with an unlocking component 6 for releasing the locking mechanism 5.

[0048] In this embodiment, as shown in Figures 7 and 8, the locking mechanism 5 includes a first toothed groove 501 formed at the inner end of the first upper frame 101, a second toothed groove 502 formed at the inner end of the second upper frame 102 and corresponding to the first toothed groove 501, a gear 503 disposed between the first toothed groove 501 and the second toothed groove 502 and capable of simultaneously locking the first toothed groove 501 and the second toothed groove 502, an unlocking block 504 disposed between the gear 503 and the first toothed groove 501 and capable of radial movement, and a linkage member 505 disposed between the unlocking block 504 and the gear 503. The linkage member 505 is inclined to engage with the unlocking block 504, and the unlocking block 504 is connected to the unlocking assembly 6 via a traction cable 7. When unlocking, the unlocking assembly 6 drives the unlocking block 504 to move radially and, through the inclined engagement, drives the linkage member 505 to move axially, thereby pushing the gear 503 out of the first toothed groove 501 and completely retracting into the second toothed groove 502 to achieve unlocking. Since there are many different locking mechanisms between two rotating parts in this technical field, no specific limitation is made here. The above is just a specific implementation of one locking mechanism, and the structure of other locking mechanisms will not be described in detail.

[0049] In this embodiment, the linkage 505 has a convex tooth 5051 extending axially toward the unlocking block 504. The unlocking block 504 has a guide portion 5041 on its side that engages with the inclined surface of the convex tooth 5051. When the unlocking assembly 6 drives the unlocking block 504 to move radially, the guide portion 5041 engages with the inclined surface of the convex tooth 5051 to drive the linkage 505 to move axially. The linkage 505 also has a protrusion 5052 extending axially toward the gear 503. The gear 503 has a limiting groove 5031 on its side corresponding to the protrusion 5052, allowing the protrusion 5052 to abut and move. The engagement of the limiting groove 5031 with the protrusion 5052 prevents the linkage 505 from rotating relative to the unlocking block 504 when the linkage 505 is lifted by the unlocking block 504 (when the linkage 505 has moved to its furthest axial position relative to the unlocking block 504 and is about to disengage).

[0050] The working principle of this invention is as follows:

[0051] When the child bassinet is unfolded, the upper frame assembly 1 and the lower frame assembly 2 are unfolded and placed flat. The support frame assembly 3 unfolds into a V-shape and is supported between the upper frame assembly 1 and the lower frame assembly 2. At this time, the locking mechanism 5 locks the upper frame assembly 1 in place, thereby keeping the entire child bassinet in the unfolded state.

[0052] When the child bassinet is folded, the locking mechanism 5 is unlocked by the unlocking component 6, and the upper frame component 1 is folded upward and retracted. The lower frame component 2 is folded upward and retracted under the linkage of the first support frame 301 and the second support frame 302, thereby completing the folding and retraction of the entire child bassinet.

[0053] The upper frame assembly 1 and the lower frame assembly 2 in this invention are both two-section structures that can be folded upwards. The two-section V-shaped support frame assembly 3 between them drives the lower frame assembly 2 to fold upwards or unfold when the upper frame assembly 1 is folded upwards or unfolded. The overall structure is simple and novel. It can not only realize the folding of the bassinet in the longitudinal direction, but also realize the folding of the bassinet in the length direction, making the folded children's bassinet smaller in size and easier to carry and store.

[0054] The locking mechanism of the present invention is set at the rotatable connection of the upper frame assembly 1, and an unlocking component 6 for unlocking the locking mechanism 5 is set at one end of the upper frame assembly 1. Therefore, when folding the child bassinet, one-handed one-button unlocking operation can be achieved without bending over, which is very convenient.
