DESCRIPTION OF EMBODIMENTS

To further described the embodiments, the present invention provides accompanying drawings. 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 FIGS. 2 and 3, in a preferable embodiment of the present invention, a skeleton assembly of an umbrella-shaped canopy on top of a playpen is provided, including: a skeleton 1 and a connection base 2, where the skeleton 1 is an umbrella-style skeleton including a notch 11 and multiple first support frames 12, where a first end of each first support frame 12 is hinged to the notch 11, such that the multiple first support frames 12 are extendable or retractable with respect to each other. The skeleton 1 further includes a runner 14 and multiple second support frames 13 corresponding to the quantity of the first support frames 12, the runner 14 is relatively disposed below the notch 11, a first end of the second support frame 13 is hinged to the runner 14, and a second end of the second support frame 13 is hinged to the first support frame 12, such that the runner 14 relatively approaches the notch 11, so as to extend the skeleton 1, or the runner 14 relatively leaves the notch 11, so as to retract the skeleton 1. A lower end of the notch 11 is provided with a locked shaft 110 extending downwards, and the runner 14 is correspondingly provided with a locking hole 140 for the locked shaft 110 to insert; the runner 14 is further provided with an elastic locking mechanism 140 configured to lock the locked shaft 110 in the locking hole 140 or unlock the locked shaft 110 from the locking hole 140. For example, the elastic locking mechanism 140 may be constructed using a spring and a slide clamping block, where the slide clamping block may be partially and externally exposed to the runner 14, to form an unlock key for a user to press.


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 FIGS. 4 to 6, the connection base 2 includes a vertical extension portion 23, a first horizontal extension portion 21, and a second horizontal extension portion 22 that intersect and are fixedly connected to each other. The vertical extension portion 23 is provided with an insertion hole 230 extending vertically, the insertion hole 230 is in insertion fit with the second end of the first support frame 12, an elastic buckle 125 is fixed to the second end of the first support frame 12, and a slot 231 used to be in clamping fit with the elastic buckle 125 is provided in an external side surface of the vertical extension portion 23 corresponding to the insertion hole 230. When the second end of the first support frame 12 is inserted in to the insertion hole 230, the elastic buckle 125 is in clamping fit with the slot 231, so as to detachably connect the connection base 2 to the first support frame 12. In another embodiment, a plurality of slots 231 may be provided at different heights, such that the elastic buckles 125 are clamped into the slots 231 at different heights to adjust the height of the skeleton 1. As shown in FIGS. 7 and 8, the connection base 2 is configured to be fixedly clamped with the corner portion 30 at the top of the playpen 3. The corner portion 30 of the playpen 3 includes a vertical rod 303, a first horizontal rod 301, and a second horizontal rod 302 that are connected at an intersection point. The vertical extension portion 23, the first horizontal extension portion 21, and the second horizontal extension portion 22 are respectively provided with a first notch 203, a second notch 201, and a third notch 202 that are used to be respectively clamped with the vertical rod 303, the first horizontal rod 301, and the second horizontal rod 302 of the corner portion 30. In this embodiment, on the premise of not changing any existing structure of the playpen 3, the connection base 2 being provided allows the skeleton 1 to be quickly mounted with or disassembled from the playpen 3. The skeleton assembly formed by the skeleton 1 and the connection base 2 can be used as an independent assembly to fit with the existing playpen 3 for use, and thus has wide application. In a more detailed embodiment, the first support frame 12 is further retractable to adjust its length, thus the skeleton assembly is suitable for playpens 3 in different sizes. After disassembled, the skeleton assembly can be retracted alone, occupying a small space. It is additionally mounted on the playpen 3 when needed again, making the use process convenient and flexible. In addition, if the connection base 2 is disassembled from the skeleton 1, the skeleton 1 can be used alone as a skeleton for a freestanding tent. In the actual use of the product in this embodiment, a tent fabric is laid on top of the skeleton 1.


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 FIGS. 9 and 10, in this embodiment, the first support frame 12 is foldable, including a first folded section 121, a second folded section 122, and a folding joint 123 connected between the first folded section 121 and the second folded section 122, with the connection base 2 connected to the second folded section 122. Folding the first support frames 12 allows the connection bases 2 with the skeleton in a retracted state to contract around the notch 11, and with the skeleton in the retracted state, the top end of the connection base 2 is slightly higher than the top end of the notch 11 (in other embodiments, the top end of the notch 11 may also be flush with a top end of the connection base 2 as the skeleton is in the retracted state). In this case, used as the support feet distributed around the notch 11, the connection bases 2 are placed towards the ground, such that the skeleton assembly in the retracted state can be placed on the ground vertically and more stably, which is further conducive to storing the skeleton assembly.


Referring to FIGS. 2 and 9, in this embodiment, a stopper 124 is fixedly to an inner side of the folding joint 123 and configured to stop the second folded section 122 from flipping towards an inner side of the first support frame 12. Because the first support frame 12 in this embodiment is connected to the connection base 2, and the skeleton assembly in the retracted state shows the smallest volume only when the second folded section 122 flips towards the external side of the first support frame 12, the stopper 124 is provided to prevent user misuse.


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.


As shown in FIG. 7, the first horizontal extension portion 21 and the second horizontal extension portion 22 both have an inverted “U”-shaped cross section, so as to respectively form the second notch 201 and the third notch 202, and inverted “U”-shaped reinforcement ribs 24 are provided on inner walls of the first horizontal extension portion 21 and the second horizontal extension portion 22, so as to improve the structural strength of the first horizontal extension portion 21 and the second horizontal extension portion 22, and to enhance the effect of the second notch 201 and the third notch 202 being respectively clamped with the first horizontal rod 301 and the second horizontal rod 302. The vertical extension portion 23 includes a first protection plate 232 and a second protection plate 234 disposed vertically and intersecting each other, an inner corner between the first protection plate 232 and the second protection plate 234 is fixedly provided with a pillar 233 extending vertically, the insertion hole 230 is disposed in the pillar 233, and an inner side of the pillar 233 is fixedly provided with the first notch 203. The first protection plate 232 and the second protection plate 234 are used as protection surfaces outside the vertical extension portion 23 for user to grasp, to prevent the hand from being pinched when the user mounts the connection base 2 on the playpen 4. The pillar 233 is provided to enhance the structural strength of the vertical extension portion 23.


As shown in FIG. 11, in this embodiment, external edges of an intersection part between the vertical extension portion 23, the first horizontal extension portion 21, and the second horizontal extension portion 22 are rounded. The round angle 26 is disposed to make go away the sharp shape at the intersection of the vertical extension portion 23, the first horizontal extension portion 21, and the second horizontal extension portion 22 to prevent accidental injury to infants.


Although the present invention is specifically illustrated and described with reference to preferred implementations, those skilled in the art should understand that without departing from the spirit and scope of the present invention as defined in the appended claims, various changes made to the present invention in form and details fall within the protection scope of the present invention.
