Description

[Technical Field]

[0001] The present invention relates to a sports protection net, and more particularly to a connecting member for deforming the frame of a sports protection net. [Background technology]

[0002] Protective netting (ball netting) is installed in sports fields to protect pitchers from being accidentally hit by high-speed balls (e.g., baseballs, softballs, etc.), thereby achieving the goals of public safety and maintaining order within the field. Taking baseball or softball fields as an example, protective netting is typically placed in front of the practicing pitcher, and most structures consist of a frame made of metal rods, with a high-strength netting surface stretched over it. Such netting must have a certain rigidity and stability to withstand the impact of high-speed balls, and must also have a certain height and width to cover the protective area. Most common protective netting is based on steel or aluminum alloy rods, which are connected by welding, screwing, or other methods to form a frame structure of the desired shape. Summary of the Invention [Problem to be solved by the invention]

[0003] However, existing commercially available protective netting (ball-proof netting) suffers from problems such as a lack of flexibility and limited assembly. Most netting is constructed by welding fixed-size rods of specific angles together to form a single unit. Once manufactured, the netting cannot be adjusted or modified to suit the needs and usage of the stadium, limiting its application within the stadium. While modularized designs have been adopted for partially disassembled or assembleable protective netting, most of the conversion joints are welded or connected by one-way screws, lacking the ability to adjust to multiple angles or directions, preventing users from quickly changing the frame angle or adapting to changes in the terrain. Furthermore, the partial conversion joint structures are simplified in design and do not take into account the need to assemble rods of different lengths and directions. This limits the joint angles between the frames, making it difficult to flexibly combine them to create various net structures, reducing the flexibility and efficiency of the overall protective system. Therefore, there has been a need in the industry for a convertible joint structure for a protective frame that can be converted in multiple directions, provides rod members that meet different specifications, and is easy to assemble and disassemble, thereby improving the flexibility of application of protective equipment and the convenience of on-site assembly.

[0004] Therefore, the inventors of the present invention believed that the above drawbacks could be improved, and after extensive research, they came up with the present invention, which effectively improves the above issues through rational design.

[0005] The present invention was made in consideration of the above circumstances, and aims to solve the above problems. That is, the purpose of the present invention is to provide a connecting member having multi-directional joints that improves the convenience and flexibility of assembling a protective net. [Means for solving the problem]

[0006] To achieve the above object, a joining member according to one aspect of the present invention includes a first frame, a second frame, a third frame, and a vertical connection portion. The first frame extends in a first direction and has a first connection portion at one end. The second frame extends in the second direction, is connected to the first frame, and has a second connection portion at one end. The third frame extends along the third direction, is connected to the first frame and the second frame, and has a third connection portion at one end. The vertical connection portion is provided between the first frame and the second frame, and extends along a direction perpendicular to the first direction, the second direction, and the third direction.

[0012] The joint member according to the first preferred embodiment of the present invention includes a first frame 10, a second frame 20, a third frame 30, and a vertical connection portion 40.

[0013] The first frame 10 is a member extending along a first direction. The first frame 10 has a first connecting portion 11 for connecting to one end of a frame portion. In this embodiment, the first connecting portion 11 has a first insertion hole 110 and at least one first positioning hole 111. The first insertion hole 110 penetrates the inside of the first frame 10 in the axial direction. The first positioning hole 111 is located on one side of the first frame 10 and is in communication with the first insertion hole 110. In this embodiment, the outer peripheral surface of the first frame 10 is approximately square.

[0014] The second frame 20 is a member extending along the second direction. The second direction and the first direction are located in opposite directions on the same axial direction, and the second frame 20 and the first frame 10 extend in directions away from each other. The second frame 20 has a second connection portion 21 for connecting to one end of another frame portion. In this embodiment, the second connection portion 21 has a second insertion hole 210 and at least one second positioning hole 211. The second insertion hole 210 penetrates the inside of the second frame 20 in the axial direction. The second positioning hole 211 is located on one side of the second frame 20 and is connected to the second insertion hole 210. In this embodiment, the outer peripheral surface of the second frame 20 is approximately square.

[0015] The third frame 30 is a member extending along a third direction. The third direction is orthogonal to the first and second directions, and the third frame 30 is perpendicular to the extension direction of the first frame 10 and the second frame 20. The third frame 30 has a third connection portion 31 for connecting to one end of another frame portion. In this embodiment, the third connection portion 31 has a third insertion hole 310 and at least one third positioning hole 311. The third insertion hole 310 penetrates the inside of the third frame 30 in the axial direction. The third positioning hole 311 is located on one side of the third frame 30 and is connected to the third insertion hole 310. In this embodiment, the outer peripheral surface of the third frame 30 is approximately square.

[0016] The vertical connection portion 40 is disposed between the first frame 10, the second frame 20, and the third frame 30, and extends along the vertical direction. The vertical direction is perpendicular to the first direction, the second direction, and the third direction. In this embodiment, the vertical connection portion 40 is a threaded hole, and a plurality of female threads 41 are provided on the inner wall surface.

[0017] The first frame 10, the second frame 20, the third frame 30, and the vertical connection portion 40 are integrally molded members.

[0018] The structure of the first frame 10, the second frame 20, and the third frame 30 forms the joint member 1 as a T-shaped member.

[0019] According to the above-described structural configuration, the connecting member 1 of the present invention is used to assemble a protective net 300 by combining and joining multiple frame members 100 and / or connecting members 200 (see FIGS. 3 to 5). When assembling, the multiple frame members 100 and multiple connecting members 1 are joined together and then assembled to form a protective net 300 with a predetermined area. Specifically, when two frame members 100 and one connecting member 1 are joined, one end of each of the two frame members 100 is connected to the first connecting portion 11 of the first frame 10 and the second connecting portion 21 of the second frame 20 via the connecting member 200, respectively, to form a continuous long side. The connecting member 200 has two positioning members 201 extending from both sides and engaging with the first positioning hole 111 of the first frame 10 or the second positioning hole 211 of the second frame 20, thereby achieving positioning. Alternatively, one of the two frame portions 100 is connected to the first connection portion 11 of the first frame 10 and the second connection portion 21 of the second frame 20, and the other is connected to the third connection portion 31 of the third frame 30, forming a 90° rotation angle.

[0020] Furthermore, at least one frame portion 100 having a male thread portion 101 at one end may be screwed into the vertical connection portion 40 to form a three-dimensional protection net 300 other than a flat one.

[0021] (Second Example) FIG. 6 is an oblique view of a connecting member 2 according to a second preferred embodiment of the present invention. Its structure is similar to that of the first preferred embodiment. However, in this embodiment, the connecting member 2 further includes a fourth frame 50 in addition to the first frame 10, the second frame 20, the third frame 30, and the vertical connecting portion 40. The fourth frame 50 is a member extending along the fourth direction. The fourth direction and the third direction are located in opposite directions along the same axis, and the fourth frame 50 and the third frame 30 extend in directions away from each other. The fourth direction is perpendicular to the first and second directions, so that the fourth frame 50 extends in a direction perpendicular to the first and second frames 10 and 20. The fourth frame 50 has a fourth connecting portion 51 for connecting to one end of another frame portion. In this embodiment, the fourth connecting portion 51 includes a fourth insertion hole 510 and at least one fourth positioning hole 511. The fourth insertion hole 510 penetrates the axial interior of the fourth frame 50. The fourth positioning hole 511 is located on one side of the fourth frame 50 and communicates with the fourth insertion hole 510. In this embodiment, the outer peripheral surface of the fourth frame 50 is substantially square.

[0022] The joint member 2 is formed as a cross-shaped member by the structure of the first frame 10, the second frame 20, the third frame 30, and the fourth frame.

[0023] In this way, compared to the connecting member 1 of the preferred first embodiment, the connecting member 2 of this embodiment can provide connection portions for the frame portion in at least four directions (five directions if the vertical connection portion 40 is included), further improving the flexibility and convenience of assembling the protective net.

[0024] To summarize the above, the connecting member of the present invention has a structure consisting of a first frame, a second frame, a third frame, an upper and lower connecting portion, and / or a fourth frame, which allows users to freely connect these frame portions, allowing users to configure sports protective frames of any shape and area as needed, and providing great convenience in assembling, disassembling, storing, and transporting the protective net.
