The following relates to outdoor products, and especially relates to a frame for a shading product and a beach umbrella having the same.
Outdoor shading products, typically beach umbrellas, are widely used in outdoor activities for sunshading or sheltering from rain. The beach umbrella usually uses a foldable frame, which can unfold or fold the sunshade umbrella, and can also be easily transported or stored. One type of beach umbrella adopts a foldable frame, which comprises a central rod located in the center and a plurality of top frame units that can be folded and unfolded, the central rod stands vertically on the ground (such as a beach), and inner end portions of the respective top frame units are connected to the upper end portion of the support rod and the respective top frame units extend radially outward along a radial direction of the central rod. Each top frame unit comprises three elongated rods, an inner end portion of a first elongated rod is hinged to an upper fixed block, an inner end portion of a second elongated rod is hinged to a lower fixed block, the upper fixed block is fixed to an upper end portion of the central rod, and the lower fixed block is fixed to the central rod and located at a distance below the upper fixed block; outer end portions of the first elongated rod and the second elongated rod are respectively hinged to different positions of a third elongated rod, and each top frame unit and the central rod form a four-bar linkage mechanism, so that each top frame unit can be folded and unfolded. However, this type of beach umbrella has the following defects: if the beach umbrella overturns on its side due to strong lateral winds or other reasons, the third elongated rod will be directly impacted. Although the third elongated rod may flip upwards to avoid direct impact, when the third elongated rod flips upwards, it will inevitably cause the first elongated rod and the second elongated rod to flip, posing a high risk of deformation or even breakage of the rods.

Each top frame unit 2 can be unfolded and folded, so that the entire frame for a shading product 100 can be folded, as shown in
In combination with the above FIGS. and as shown in
Furthermore, in this embodiment, each top frame unit 2 comprises two second top rods 22, which are connected in parallel between the same joint 25 and first slider 4 to enhance the strength of the top frame unit 2. There is a gap between the two second top rods 22, and the slant support rod 24 passes between the two second top rods 22 and is respectively connected to the first top rod 21 and the second slider 5. The length of the slant support rod 24 is less than that of the first top rod 21 and the second top rod 22, and the distance between the connection of the slant support rod 24 and the first top rod 21 and the outer end portion of the first top rod 21 shall be less than half of the length of the first top rod 21, and the sum of this distance and the length of the slant support rod 24 shall be less than or equal to the length of the second top rod 22. In addition, the difference in length between the first top rod 21 and the second top rod 22 is less than one tenth of the length of the second top rod 22; the length of the first top rod 21 is less than the length of the second top rod 22. When the frame for a shading product 100 is in the folded state, the upper end portion of the first top rod 21 and the upper end portion of the second top rod 22 are close to each other (the two are basically at the same level, or the height difference is much less than 1/10 of the length of the first top rod 21), and the lower end portion of the first top rod 21 is higher than the upper end portion of the second top rod 22. When the frame for a shading product 100 is in the folded state, in each top frame unit 2, the slant support rod 24 is accommodated between the two second top rods 22 to make full use of the internal space and avoid the excessive overall volume after folding.

As shown in
The joint 25 has an impact cushion portion 253 that lands on the ground when the frame for a shading product 100 overturns on its side, when the frame for a shading product 100 overturns on its side to the ground or is placed tilted to the ground, the impact cushion portion 253 of the joint 25 lands on the ground to support the entire frame; at this time, the impact cushion portion 253 protrudes outward relative to the first pivot a1, the second pivot a2, the inner end portion of the extension rod 23 and the outer end portion of the second top rod 22, which effectively avoids the end portions of the rods (especially the outer end portion of the second top rod 22) from directly touching the ground, thereby reducing the risk of bending, deformation, or breakage of the rods.
The joint 25 comprises a body 251 and a metal reinforcement sheet 252 fixedly connected to the body 251, and the body 251 is a plastic member that can be processed using an integral injection molding process. The metal reinforcement sheet 252 can be made of alloy sheets with better strength such as steel sheets. Further, the metal reinforcement sheet 252 extends from the first pivot a1 to the second pivot a2, and the two end portions of the metal reinforcement sheet 252 are respectively provided with pivot holes for the first pivot a1 and the second pivot a2 to pass through. The first pivot a1 passes through upper end portions of the body 251 and the metal reinforcement sheet 252, the second pivot a2 passes through lower end portions of the body 251 and the metal reinforcement sheet 252, and the metal reinforcement sheet 252 can be connected to the body 251 via the first pivot a1 and the second pivot a2, effectively strengthening the connection strength between the first top rod 21, the second top rod 22, and the extension rod 23. In this embodiment, each top frame unit 2 comprises two second top rods 22, which are connected in parallel to the joint 25, and accordingly there are two metal reinforcement sheets 252 respectively arranged on two opposite sides of the body 251. The body 251 of joint 25 further has a pipe plug 251a, the pipe plug 251a is inserted into the outer end portion of the first top rod 21 and fixed to the first top rod 21 through a fastener such as a screw or a rivet.

As shown in
Hooking holes 263 are provided on the wings 262 to facilitate the connection of the enclosing cloths. In this embodiment, the hooking holes 263 run through the wings 262 in the up-down direction. The hooking holes 263 has clamping groove portions 263a, and the clamping groove portions 263a has openings facing the outer or lower sides of the umbrella frame. The hooking holes 263 further have guide groove portions 263b, which are connected to the clamping groove portions 263a through the above openings; the hole diameter or width of the guide groove portion 263b is greater than that of the clamping groove portions 263a, and the overall hooking hole 263 is in the shape of a gourd; further, the guide groove portions 263b are circular holes, and the clamping groove portions 263a are U-shaped holes. In some other embodiments, the hooking holes 263 are only composed of clamping groove portions 263a, and the openings are opened on the outer edge of the connecting sheet 26, that is, the clamping groove portions 263a extend inward from the edge of the connecting sheet 26, thereby facilitating the connection pieces on the enclosing cloths to slide in.
The enclosing cloths of the outdoor shading product mentioned above is connected with several connecting pieces, which comprise connecting pins, and side walls of the connecting pins have recessed portions (such as circular grooves). When mounting the enclosing cloths, the connecting pins are inserted into the guide groove portions 263b and slided into the clamping groove portions 263a from the openings or are directly slided into the clamping groove portions 263a from the openings, and the recessed portions are stuck on the wings 262 to prevent the connecting pins from sliding out of the clamping groove portions 263a. This embodiment is different from the conventional connection method between the cloth cover and the frame, and has good connection strength. Not only is the connection of the cloth cover convenient, but also the connection is reliable, reducing the risk of tearing or damage to the connections between the cloth cover and the rods during the folding or unfolding process of the rods. After the umbrella frame is unfolded, under the tension of the umbrella cloth itself, the connecting pins remain in a state of mutual clamping with the connecting sheet 26, without sliding out from the openings.
The frame for a shading product 100 is provided with a locking mechanism. When the frame for a shading product 100 is in the unfolded state, the locking mechanism is in a locked state, and the first slider 4 and the second slider 5 are locked to each other.

Both the first top rod 21 and the second top rods 22 are tilted, and their inner end portions are higher than their outer end portions. The slant support rod 24 is also arranged obliquely, and the outer end portion is higher than the inner end thereof.
When the frame for a shading product 100 is in a folded state, each top frame unit 2 is close to the central rod 1. Specifically, the joint 25 of each top frame unit 2 and the central rod 1 (specifically the lower end portion of the uppermost sub rod 11) are close to each other, that is, the outer end portion of the first top rod 21, the outer end portion of the second top rod 22, the slant support rod 24 and the extension rod 23 are close to the central rod 1; the first slider 4 and the second slider 5 are detached from each other and slide upwards until they are close to the top cap 3, and the spring 6 is compressed; the inner end portion of the second top rod 22 and the inner end portion of the first top rod 21 are close to each other.
When the frame for a shading product 100 is folded, the lugs 411 on the two locking members 41 are pressed inwards, the second slide 5 is moved downwards and is detached from the first slide 4, driving the slant support rod 24 to close to the central rod 1, so that the first top rod 21 and the second top rod 22 are then close to the central rod 1, and at the same time, the first slide 4 is pushed upward to close to the top cap 3; finally, the extension rod 23 is flipped upwards and close to the first top rod 21 to complete the folding of the frame. When the above shading product is unfolded, the extension rod 23 is flipped downwards to unfold, pushing the second slider 5 upwards, at the same time, with the assistance of the reset force of the spring 6, the first slider 4 is slided downwards until the locking members 41 are inserted into the second slider 5, each top frame unit 2 is fully unfolded, and the entire frame is directly locked in the unfolded state.
The frame for a shading product 100 of this embodiment can be applied to outdoor shading products such as beach umbrellas, and when the shading product falls to the ground, the extension rod 23 flips upwards to cushion the impact force and improve the strength of the frame, meanwhile the top frame unit 2 does not need to be deformed or folded. The frame for a shading product 100 can be unfolded and folded, and the folded volume is small. Wherein, two second top rods 22 of each top frame unit 2 are provided, improving the overall strength of the top frame units, while the size of the frame for a shading product 100 after being folded will not increase. In addition, the spring 6 between the top cap 3 and the first slider 4 provides assistance when unfolding the frame for a shading product 100, which is more labor-saving when unfolding the product. Except for the extension rod 23, the entire top frame unit 2 is linked with the first slider 4 and the second slider 5, making it easier to unfold and fold; while the extension rod 23 is pivotally connected to the joint 25, when the product falls to the ground, the extension rod 23 will flip upwards to cushion the impact, avoiding direct impact on the end portion of the extension rod 23 and reducing the risk of breakage or deformation of the extension rod 23.
