The present invention relates to infant care products, in particular to, a skeleton assembly of an umbrella-shaped canopy.
As a common infant care product, baby playpens can separate out a specific play region to ensure the safety of infants, and therefore are widely used.
For infant playpens, there is currently a market demand: The playpen purchasers hope to additionally mount a canopy on top of the playpen, so as to provide mosquito protection, warming, shading, and other effects. However, for ease of storage, conventional infant playpens are generally foldable, and canopies are retractable as well. If the skeletons of the canopies and those of the playpens are assembled together, conflicts are likely to occur during folding, resulting in a difficult design process. As a result, the currently available infant care products in the market either consist of a single canopy or a single playpen, and there has not been a solution to well integrate the two.
Therefore, to resolve the foregoing problems, the present invention provides a skeleton assembly of an umbrella-shaped canopy on top of a playpen, which can be quickly mounted with or disassembled from an infant playpen.
The present invention is implemented using the following technical solutions.
The present invention provides a skeleton assembly of an umbrella-shaped canopy on top of a playpen, including a skeleton and a connection base, where the skeleton is an umbrella-style skeleton including a notch and multiple first support frames, where a first end of each first support frame is hinged to the notch, such that the multiple first support frames are extendable or retractable with respect to each other; and the connection base is provided in plurality to correspond to the quantity of the first support frames, a second end of each first support frame is fixedly connected to one of the connection bases, the connection base is configured to be fixedly clamped with a corner portion at the top of the playpen, the corner portion of the playpen includes a vertical rod, a first horizontal rod, and a second horizontal rod that are connected at an intersection point, and the connection base is provided with a first notch, a second notch, and a third notch that are used to be respectively clamped with the vertical rod, the first horizontal rod, and the second horizontal rod of the corner portion.
In an embodiment, preferably, the first support frame is foldable, folding the first support frames allows the connection bases with the skeleton in a retracted state to contract around the notch, and with the skeleton in the retracted state, a top end of the notch is flush with a top end of the connection base, or the top end of the connection base is slightly higher than the top end of the notch.
In an embodiment, preferably, the first support frame includes a first folded section, a second folded section, and a folding joint connected between the first folded section and the second folded section, the connection base is connected to the second folded section, and a stopper is fixedly to an inner side of the folding joint and configured to stop the second folded section from flipping towards an inner side of the first support frame.
In an embodiment, preferably, the connection base includes a vertical extension portion, a first horizontal extension portion, and a second horizontal extension portion that intersect and are fixedly connected to each other, any two of extension directions of the vertical extension portion, the first horizontal extension portion, and the second horizontal extension portion are perpendicular to each other, and the first notch, the second notch, and the third notch are respectively provided in the vertical extension portion, the first horizontal extension portion, and the second horizontal extension portion.
In an embodiment, preferably, the first horizontal extension portion and the second horizontal extension portion both have an inverted “U”-shaped cross section, so as to respectively form the second notch and the third notch, and inverted “U”-shaped reinforcement ribs are provided on inner walls of the first horizontal extension portion and the second horizontal extension portion.
In an embodiment, preferably, the vertical extension portion is provided with an insertion hole extending vertically, the insertion hole is in insertion fit with the second end of the first support frame, an elastic buckle is fixed to the second end of the first support frame, and at least one slot used to be in clamping fit with the elastic buckle is provided in an external side surface of the vertical extension portion corresponding to the insertion hole.
In an embodiment, preferably, the vertical extension portion includes a first protection plate and a second protection plate disposed vertically and intersecting each other, an inner corner between the first protection plate and the second protection plate is fixedly provided with a pillar extending vertically, the insertion hole is disposed in the pillar, and an inner side of the pillar is fixedly provided with the first notch.
In an embodiment, preferably, external edges of an intersection part between the vertical extension portion, the first horizontal extension portion, and the second horizontal extension portion are rounded.
In an embodiment, preferably, the skeleton further includes a runner and multiple second support frames corresponding to the quantity of the first support frames, the runner is relatively disposed below the notch, a first end of the second support frame is hinged to the runner, and a second end of the second support frame is hinged to the first support frame, such that the runner relatively approaches the notch, so as to extend the skeleton, or the runner relatively leaves the notch, so as to retract the skeleton.
In an embodiment, preferably, a lower end of the notch is provided with a locked shaft extending downwards, and the runner is correspondingly provided with a locking hole for the locked shaft to insert; the runner is further provided with an elastic locking mechanism configured to lock the locked shaft in the locking hole or unlock the locked shaft from the locking hole.
The present invention has the following beneficial effects: In the present invention, on the premise of not changing any existing structure of the playpen, the connection base being provided allows the skeleton to be quickly mounted with or disassembled from the playpen. The skeleton assembly formed by the skeleton and the connection base can be used as an independent assembly to fit with the existing playpen for use, and thus has wide application. After disassembled, the skeleton assembly can be retracted alone, occupying a small space. It is additionally mounted on the playpen when needed again, making the use process convenient and flexible.

These drawings are part of the disclosure of the present invention and are primarily used to illustrate embodiments and can be used with reference to the relevant description in the specification to explain the operating principles of the embodiments. Referring to this content, ordinary skilled persons in this field should understand other possible implementations and the advantages of the present invention. The components in the figure are not drawn to scale, and similar component symbols are typically used to represent similar components.
The present invention is further described with reference to the accompanying drawings and specific implementations.
As shown in
The skeleton 1 in this embodiment is an umbrella-style skeleton without a central rod. In another embodiment, a central rod can extend downwards from the lower end of the notch 11, the runner 14 is slidably connected to the central rod, and forms a lockable fitting relationship with the central rod.
The connection bases 2 are correspondingly provided with multiple first support frames 12, where the second end of each first support frame 12 is fixedly connected to a connection base 2. As shown in
The skeleton 1 may be fixedly connected to the connection base 2 in another manner of, for example, bounding. In this embodiment, the connection base 2 is detachably connected to the first support frame 12. During actual assembly, the connection base 2 may be mounted on the playpen 3, and then the skeleton 1 is connected to the connection base 2. Because the skeleton 1 is relatively large when extended, if the connection base 2 is mounted on the playpen 3 in a case that the skeleton 1 has been already fixedly pre-connected to the connection base 2, the connection base 2 needs to be aligned with the corner portion 30 and overcome the tension of the skeleton 1, and so many parts of the connection base 2 and the corner portion 30 need to be positioned for alignment, making the alignment more difficult and the operation inconvenient. Under such arrangement of this embodiment, after the connection base 2 is mounted on the playpen 3, the first support frame 12 only needs to be aligned with the connection base 2. The skeleton 1 is clamped with the connection base 2 through insertion, such that the two are convenient to mount and position, which is greatly conducive to the assembly process. If the skeleton assembly needs to be disassembled, the skeleton 1 is disassembled off with the connection base 2. As shown in
Referring to
In this embodiment, four first support frames 12 and four connection bases 2 are correspondingly disposed at four corner portions 30 of the dimetric playpen 3. However, in other embodiments, if there are more or fewer corner portions 30 of the playpen 3 (for example, a pentagonal playpen or triangular playpen), the quantities of the first support frames 12 and the connection bases 2 may be also correspondingly increased or decreased. In this embodiment, any two of the vertical rod 303, the first horizontal rod 301, and the second horizontal rod 302 on the dimetric playpen 3 are perpendicular to each other, and therefore any two of the extension directions of the vertical extension portion 23, the first horizontal extension portion 21, and the second horizontal extension portion 22 of the connection base 2 are also perpendicular to each other, to be suitable for the vertical rod 303, the first horizontal rod 301, and the second horizontal rod 302. When an angle formed between any two of the vertical rod 303, the first horizontal rod 301, and the second horizontal rod 302 changes, a corresponding angle formed between any two of the vertical extension portion 23, the first horizontal extension portion 21, and the second horizontal extension portion 22 may be changed adaptively.
