Description

[Detailed description of the invention] This invention relates to an improvement of a net post for installing a sports net used for tennis, volleyball, badminton, half tennis, mini tennis, etc. , it is constructed so that it can be disassembled into a post-supporting connecting pipe member and a connecting fixing member, and can be assembled, so that it can be transported in a small volume and can be carried into a gymnasium through a narrow passage, and To provide a movable assembly net post for sports that can be assembled extremely easily and robustly, and the net post can be stably supported upright.

A conventional net post of this kind has a pair of posts 2, 2 fixedly supported by welding on a stable pipe 1, as shown in Fig. 10.
A post support connecting pipe 3 was passed between each of the stabilizing pipes of the above-mentioned pair of posts, and its both ends were welded and fixed to the inside of the stabilizing pipes 1, 1, so that it could not be disassembled. Yes, when transporting to the destination by vehicle, it is not possible to load a large number of net posts, the transport efficiency is poor, and if the passage leading to the gymnasium at the destination is narrow, it is impossible to transport it to the gymnasium. It became.

Furthermore, when stretching the net 4 over the conventional net posts 2, 2, as shown in FIG. However, due to the tension of this cable, the posts 2, 2 incline inward as shown by the chain line. This inclination action causes the stabilizing pipes 1, 1, and the post support connections fixed to the above-mentioned stabilizing pipes transmitted to pipe 3,
The connecting pipe 3 is bent as shown by the chain line.

The above-mentioned bending of the connecting pipe not only makes the upright state of the posts 2, 2 unstable, but also has drawbacks such as causing the stretched net 4 to become crooked.

This invention improves the above-mentioned drawbacks of known net posts.

This invention will be explained as follows with regard to the embodiment shown in the drawings.

The assembled net post for sports of this invention connects and fixes a pair of symmetrical post members A and B, a post-supporting connecting pipe member C, and post members A and B and a post-supporting connecting pipe member C. A pair of connecting and fixing members, E and E.

Example of post members A and B...The left and right pair of post members A and B are attached to the lower surface 11c of a stable pipe 11 made of a square pipe, as shown in FIGS. 2, 8, and 9. ,
The threaded rod portions 12a, 1 of each of the pair of height adjustment legs 12.12
Attach 2a so that it can be screwed in and unscrewed.

13 is the screw rod part 12a installed in the stabilizing pipe 11.
, 12a is a guide female screw member.

At the center of the upper surface 11b of the stable pipe 11, the lower part of a round or square pipe-shaped post 14 is welded and fixed to stand upright.

In addition, in the center of the inner surface 11a of the stable pipe 11, a connecting member 15a, 15b, each having a U-shaped or arc-shaped cross section, has its U-shaped or arc-shaped inner surfaces facing each other vertically, and the end surfaces of each are welded to form a connecting portion. 15.

Upper and lower connecting members 15a and 15b form a bolt insertion hole 16 penetrating from the inner surface 14a near the upper part of the pipe-shaped post 14 to the outer surface 14b, and constitute the connecting portion 15.
A bolt insertion hole 17 is formed therethrough.

Embodiment of the post-supporting connecting pipe member C...The post-supporting connecting pipe member C is, as shown in FIGS. It is formed as a single piece of square or round pipe that is tightly fitted into the respective connecting parts 15, 15 of B, or it is formed as a joint pipe that is used by connecting several pipes.

In any case, a bolt insertion hole 18 is provided in the portion to be inserted into the connection part 15.15 at a position corresponding to the position of the bolt insertion holes 17, 17 of the connection part 15.15.

In addition, when the post supporting connecting pipe member C is constructed by connecting joint pipes C□, C2, etc. as shown in Fig. 4, when the joint pipes C1, C2, etc. are square pipes, As shown in FIG.
The U-shaped inner surfaces of the connecting pipes C1 and C2 are covered from above and below the abutting portions S of the connecting pipes C1 and C2, with the U-shaped inner surfaces of the connecting pipes C1 and C2 facing each other vertically.
Bolts 20 passing through 9a, 19b and the U-shaped joint pipes C1, C2, . . . are inserted and fixed with nuts 21.

As shown in FIGS. 1 and 7, a center ring 22 is attached to the left and right center portions of the post support connecting pipe member C.

Connecting members 19a and 19b for connecting the connecting pipes C1, C2, . . . each having a round cross section are used having an arcuate cross section.

Connecting and fixing member, E... Connecting and fixing member, E is the post 14 of each of the post members A and B, as shown in FIG.
．． The inner surfaces 14a, 14 of 14 near the upper part of the bolt insertion hole 16 are connected to the portions of the post support connecting pipe member C on both sides that are inserted into the connecting portions 15, 15 of the post members A, B. The hanging post 23 made of a square pipe or a round pipe and its ends are cut off at 45 degrees, and a flat fixing plate 25. If the post is made of a round pipe, a fixing plate 25.25 having an arcuate cross section is welded to 25.

The bolt insertion hole 1 of the post 14 is provided in the upper fixing plate 25.
A bolt insertion hole 27 is formed at a position corresponding to 6, and a bolt insertion hole 26 is also provided in the lower fixing plate 25.

28 is the floor.

The above components are disassembled into a pair of boss 1 members A and B, a post-supporting connecting pipe member C, a pair of connecting fixing members, and E, and then transported and transported to a stadium such as a gymnasium. To assemble, as shown in FIG.
5. Each bolt insertion hole 17, 18 inserted in 15,
A bolt 30 is inserted into 17 and 18 and a nut 31 is fixed.

If the post support connecting pipe member C is several joint pipes C
1, C2..., the bolt 20 and nut 2 are connected by connecting members 19a and 19b.
1, and connect the post support connecting pipe member C.
Use as.

Next, the fixing plate 25 above each of the connecting fixing members E.
25 through the respective bolt insertion holes 27, 27 on the left and right posts 1.
4. Insert the bolt 30 so that it matches the bolt insertion holes 16, 16 of 14, and fix it with the nut 31.

A bolt 30 is also inserted into the bolt insertion hole 26 of the lower fixing plate 25, passes through the post support connecting pipe member C, and is fixed with a nut 31.

Next, the screw rods 12 of the adjusting legs 12.12 of post members A and B
a, 12a are screwed to form a gap 1 between the lower surface of the post support connecting pipe member C and the floor surface 28, and to hold and adjust the post support connecting pipe member C in a horizontal state.

Next, attach net F to posts A and B.

By tensioning the net and fixing the cable 32 at the top of the net to the tops of both posts A and B in a tensioned state, even if an acting force is applied that causes the tops of posts A and B to incline inward, Due to the existence of the connecting and fixing member E, the inward tilting is prevented, and even if a slight inclination occurs and the post supporting connecting pipe member C is slightly bent, the height adjusting legs will not be able to move. A gap 1 is formed between the contact part of the floor No. 12 and the post support connecting pipe member C, and as shown in FIG. Since the sports net is supported by the height-adjustable legs 12 without touching each other, the posts 14, 14 can be stably erected, and the net can be ideally stretched.

As mentioned above, this invention is constructed so that it can be disassembled and assembled into a pair of posts, a connecting pipe member for supporting the post, and a connecting fixing member, so it can be transported in a small volume and can be transported more efficiently. It is ideal because it has good stability and can be carried into the gymnasium through narrow passageways, is extremely easy to assemble, and is sturdy and allows the posts to stand up stably in a nearly parallel state. There are effects such as being able to set up a net.
