Description

Technical Field

[0001] This utility model relates to the technical field of accessories for outdoor seating such as hanging chairs and portable chairs, and in particular to a detachable sunshade and its frame. Background Technology

[0002] Traditional awnings on the market mostly use rigid I-beam or umbrella-shaped structures with tubing and other connections. These structures involve numerous metal pipes, are complex, inconvenient to store, have poor adjustment flexibility, and are costly. Furthermore, they are bulky and heavy when folded, have poor versatility, and are difficult to integrate with different products.

[0003] Especially in detachable scenarios, existing structures still occupy a significant amount of space when folded and lack sufficient stability when unfolded, making them unsuitable for installation needs in different environments. Furthermore, the simple connector structure of traditional frames easily leads to loosening after folding or insufficient support when unfolded. For awnings requiring frequent disassembly and angle adjustments (such as temporary outdoor sunshades, portable outdoor tables and chairs), existing technologies struggle to simultaneously meet the combined requirements of lightweight design, rapid storage, and stable support. Utility Model Content

[0004] To solve the above-mentioned technical problems, the first objective of this utility model is to provide a detachable sunshade frame that is easy to fold and has a small storage volume. The second objective of this utility model is to provide a detachable sunshade.

[0005] To achieve the first objective of the above-mentioned utility model, the present utility model adopts the following technical solution:

[0006] A detachable sunshade frame includes multiple sets of flexible support rods and rotating components. The two ends of the flexible support rods are respectively connected to the corresponding rotating components. The rotating components cause the multiple sets of flexible support rods to at least partially overlap or be distributed at intervals. Each set of flexible support rods includes multiple short support rods and at least one flipping component. The two ends of the flipping component are respectively connected to a short support rod. The flipping component causes two short support rods to be side by side or extend in a straight line.

[0007] As a preferred embodiment, the flipping component includes a first flipping block and a second flipping block. One end of the first flipping block is provided with a connecting arm, and one end of the second flipping block is provided with a connecting notch. The connecting arm is inserted into the connecting notch, and the first flipping block and the second flipping block are rotatably connected by a hinge post passing through the connecting arm and the connecting notch. The other ends of the first flipping block and the second flipping block are respectively provided with a socket A and a socket B.

[0008] As a preferred embodiment, the edge of the connecting recess of the second flip block is also provided with a locking boss. When the first and second flip blocks are opened and straightened, one side of the connecting arm abuts against the side wall of the connecting recess, and the other side abuts against the locking boss. This structural design enhances the stability of the connection, while ensuring smooth flipping. The locking boss provides a lock when unfolded to prevent accidental folding.

[0009] As a preferred embodiment, locking protrusions are provided on both sides of the opening of the connecting notch, and the distance between the two locking protrusions is less than or equal to the thickness of the connecting arm. When the first flip block and the second flip block are folded together, the locking protrusions are located on the outside of the connecting arm.

[0010] The above structure ensures that the flip-up component remains stable and does not bend when straight. When folding, manual pressing causes the inner side of the connecting arm to push the two locking protrusions outward, and the connecting arm to rotate inward. The two locking protrusions press against the upper and lower end faces of the connecting arm respectively until the connecting arm rotates inward to its final position. At this point, the locking protrusions are located on the outer side of the connecting arm, restricting the opening of the flip-up component and ensuring that the flip-up component will not easily open after folding.

[0011] As a preferred embodiment, the short support rod is a flat fiber rod, and the cross-sectional shapes of the sockets A and B are the same as those of the short support rod. The flat fiber rod is lightweight and flexible, and the matching design between the flat fiber rod and the socket ensures that the end of the flat fiber rod is completely wrapped by the socket, which helps to enhance the connection strength.

[0012] As a preferred embodiment, the rotating component is further provided with a mounting clip, the mounting clip is provided with a dovetail groove connector, and the dovetail groove connector has locking edges on both sides; as long as a matching dovetail groove connector is attached to any product, the sunshade can be adapted, so the sunshade of this application has obvious advantages in terms of compatibility.

[0013] As a preferred embodiment, the rotating component includes multiple sets of rotating blocks, and the rotating blocks and the mounting clips form an infinitely adjustable angle through a toothed structure. This allows users to adjust the angle of the sunshade as needed to adapt to different installation environments.

[0014] As a preferred embodiment, the number of rotating blocks is the same as the number of flexible support rods.

[0015] As a preferred embodiment, a support bar assembly is further provided between two adjacent sets of flexible support rods. The support bar assembly includes two support bars hinged together, one end of which is hinged to one of the two adjacent sets of flexible support rods. The other end of each support bar has an annular guide groove, and a limiting block is fixed within the annular guide groove. The limiting block of one support bar moves within the annular guide groove of the other support bar as the support bar moves. When the two support bars are extended and folded together, the two limiting blocks are in a resisting state. The hinged design of the support bar assembly, combined with the horizontal limiting structure, improves the lateral stability in the extended state and prevents the frame from deforming or collapsing.

[0016] To achieve the second objective of the above-mentioned utility model, the present utility model adopts the following technical solution:

[0017] A detachable sunshade includes a detachable sunshade frame as described in any of the above claims, wherein the detachable sunshade frame is further provided with fabric.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The sunshade frame of this utility model combines short support rods with flip-up components. The flexible support rods can be folded in sections or unfolded in a straight line. After multiple sections are folded, they can be bundled together. The structure is simple, the packaging volume is small, and it is convenient for transportation and storage.

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0038] like Figures 1 to 3 As shown, a detachable sunshade frame includes multiple sets of flexible support rods 100 and rotating parts 3. Each rotating part 3 is also equipped with mounting clips 5. The two ends of each flexible support rod 100 are connected to a corresponding rotating part 3. The rotating parts 3 cause the multiple sets of flexible support rods 100 to at least partially overlap or be spaced apart. Each set of flexible support rods 100 includes multiple short support rods 1 and at least one flipping part 2. Each end of the flipping part 2 is connected to a short support rod 1, and the flipping part 2 causes two short support rods 1 to be placed side-by-side (e.g.,...). Figure 4 (As shown) or it extends in a straight line.

[0039] The sunshade frame of this utility model consists of multiple sets of continuous flexible support rods 100, each set of flexible support rods 100 being composed of multiple short support rods 1, which reduces the volume when folded. The sunshade frame is equipped with mounting clips 5 at both ends for fixing to the hanging chair bracket 6 (e.g., Figure 9 and Figure 10 As shown), the mounting clip 5 is provided with a dovetail groove connector 51, and the dovetail groove connector 51 is provided with a retaining edge 52 on both sides. The dovetail groove connector 51 is also provided with two protruding ridges 53 at intervals.

[0040] The dovetail joint 51 and the dovetail interface 60 form a concave-convex mating plug-in structure, making installation simple and convenient. Simultaneously, the retaining edge 52 engages with the elongated groove 61 on the dovetail interface 60, making the sunshade structure more stable after installation and preventing wobbling. Furthermore, the sunshade can be adapted to any other product as long as it is fitted with a matching dovetail interface. Therefore, the sunshade of this invention has a significant advantage in terms of compatibility. Moreover, changing the size of the sunshade can be achieved simply by modifying the length of each short support rod 1, greatly reducing development difficulty.

[0041] The specific structure of the flipping component 2 of this utility model is as follows: Figure 5 and Figure 6 As shown, the device includes a first flipping block 21 and a second flipping block 22. One end of the first flipping block 21 has a connecting arm 210, and one end of the second flipping block 22 has a connecting recess 220. The connecting arm 210 is inserted into the connecting recess 220, and a hinge pin 23 passes through the connecting arm 210 and the connecting recess 220, allowing the first flipping block 21 and the second flipping block 22 to be rotatably connected. The other ends of the first flipping block 21 and the second flipping block 22 are respectively provided with insertion ports A211 and B222. The short support rod 1 can be a flat fiber rod, or other flexible material rods are also applicable. The cross-sectional shapes of insertion ports A211 and B222 are the same as the cross-sectional shape of the short support rod 1.

[0042] The edge of the connecting recess 220 of the second flip block 22 is also provided with a locking boss 221. When the first flip block 21 and the second flip block 22 are opened and straightened, one side of the connecting arm 210 abuts against the side wall of the connecting recess 220, and the other side abuts against the locking boss 221.

[0043] As a further preferred embodiment, locking protrusions 221 are provided on both sides of the opening of the connecting notch 220. The distance between the two locking protrusions 221 is less than or equal to the thickness of the connecting arm 210. When the first flip block 21 and the second flip block 22 are folded together, the locking protrusions 221 are located on the outside of the connecting arm 210. At the same time, the edges of the locking protrusions 221 are chamfered, that is, the contact surfaces between the inner and outer sides of the connecting arm 210 and the locking protrusions 221 are all arc surfaces. This allows the chamfered parts of the locking protrusions 221 to guide the connecting arm 210 when the user opens or folds the flipped part, making it easier and smoother for the connecting arm 210 to push open the locking protrusions 221.

[0044] The above structure ensures that the flip-up component remains stable and does not bend when straight. When folding, manual pressing causes the inner side of the connecting arm to push the two locking protrusions outward, and the connecting arm to rotate inward. The two locking protrusions press against the upper and lower end faces of the connecting arm respectively until the connecting arm rotates inward to its final position. At this point, the locking protrusions are located on the outer side of the connecting arm, restricting the opening of the flip-up component and ensuring that the flip-up component will not easily open after folding.

[0045] The folding direction of the flip-up piece 2 is horizontal, making the structure more streamlined and easier to fold. It also features a locking boss 221 structure. When the flip-up piece 2 is fully unfolded, there will be a crisp sound and damping feedback to inform the user that the sunshade frame has been fully unfolded and fixed.

[0046] The rotating component 3 includes multiple sets of rotating blocks, the number of which is the same as the number of flexible support rods. In this embodiment, there are two sets of flexible support rods, and correspondingly two rotating blocks, namely a first rotating block 31 and a second rotating block 32. One end of each set of flexible support rods is connected to the first rotating block 31 and the second rotating block 32, respectively. After the sunshade is fixed, the mounting clip 5 remains stationary, and the first rotating block 31 and the second rotating block 32 rotate back and forth through their internal toothed structure to achieve stepless adjustment of the sunshade angle.

[0047] like Figure 7 and Figure 8 As shown, a support strip assembly 4, made of plastic, is also provided between two adjacent sets of flexible support rods 100. The support strip assembly 4 is used to expand each set of flexible support rods, making the fabric set on the flexible support rods taut. The support strip assembly 4 includes two support strips 41 that are hinged to each other. One end of the two support strips 41 is respectively hinged to the two adjacent sets of flexible support rods 100. The other end of the support strip 41 is provided with an annular guide groove 42, and a limiting block 43 is fixed in the annular guide groove 42. The limiting block 43 of one support strip 41 moves within the annular guide groove 42 of the other support strip 41 as the support strip 41 moves. When the two support strips 41 are opened and straightened, and when they are folded and brought together, the two limiting blocks 43 are in a resisting state. The hinged design of the support strip assembly, combined with the horizontal limiting structure, improves the lateral stability in the unfolded state and prevents the frame from deforming or collapsing.

[0048] This embodiment also discloses a detachable sunshade, including a detachable sunshade frame 10 as described in any of the above, wherein the detachable sunshade frame 10 is further provided with fabric.

[0049] The flexible support rod of this utility model can be folded horizontally by 100 degrees, which can not only meet the requirements of normal folding but also save storage space, while making the appearance more concise. The dovetail tenon and mortise connection between the sunshade and the matching products makes this sunshade highly adaptable and can be developed in multiple product lines.

[0050] This invention solves the core problems of traditional sunshades, such as large storage volume, inflexible adjustment, and poor stability, by combining a split short rod, multi-directional rotating parts, a self-locking flip structure, and lightweight materials. It is especially suitable for outdoor sunshade needs that require frequent disassembly and adaptation to multiple scenarios.
