Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a small portable golf practice net for personal use, and particularly to a portable golf practice net that can be disassembled and assembled. It is about improvement.

[Prior art and its problems] Conventionally, a portable net for golf practice is shown in FIG.
No. 2832, Registered Design No. 360639, etc.), steel pipes are assembled into a substantially rectangular solid, and the sides of the pipes are assembled.
Or put a net on the top.

However, this type of portable golf net is made by assembling steel pipes, and connects two approximately rectangular supporting frames rotatably on one side, and between them is a banner with a target marked on it, and a banner with a target marked on it, and a frame with a target attached to it. It is equipped with a net to catch the hit ball. Therefore, when the banner or net is hit by a ball, the support frames on both sides are pulled together, resulting in a narrowing of the gap between the support frames and the problem that the banner or net becomes loose.

In addition, in recent years, such problems have been solved in order to improve portability.
This became apparent because the material and dimensions of the support frame were devised to reduce its weight.

(Objective of the invention, outline of structure) The present invention eliminates the above-mentioned problems, does not impair the conventional features of easy assembly and light weight, and does not change the original assembled state once assembled. The purpose of this project is to obtain a portable net assembly structure with a simple structure, in which a plurality of substantially rectangular supporting frames made by bending pipe materials are connected to the vertical axis on their negative sides. It is characterized in that it is connected rotatably around the frame, a net is stretched between adjacent support frames, and a holding rod is provided between adjacent support frames to maintain a constant distance between them.

[Function] After the support frame 2 is assembled, the portable net 1 is attached to the holding rod 5.
Since the space between the adjacent support frames 2 is fixed by , even when the banner 7 or the net 4 having the target is hit by a strong ball, the support frame will maintain its original assembled shape, and the banner or net will loosen. Problems can be prevented before they occur.

[Example] Hereinafter, the present invention will be explained with reference to the illustrated example. A portable golf practice net 1 has four supporting frames 2 each having a substantially C shape.
and a strut 3 that rotatably connects these, a net 4 stretched between at least two adjacent support frames 2 connected to each other, and a holding rod 5 that maintains a constant spacing between them. .

The support frame 2 includes a vertical steel pipe 2a and upper and lower horizontal pipes 2b, 2b.
, and upper and lower shaft tubes 2c, 2c coaxially mounted opposite to one end of the horizontal tubes 2b, 2b, forming a substantially C-shape. The space between the upper and lower shaft tubes 2c, 2c is complemented by two main pillars of a strut 3, which will be described later, so that the assembled structure has a substantially rectangular shape. 2d is a plurality of hooks for fixing the net 4, and the upper horizontal pipe 2b and the vertical pipe 2
It is fixed to the upper part of a by welding or brazing. 2e is vertical pipe 2a and horizontal pipe 2b, 2b or axial pipe 2c
, 2c, but this does not necessarily have to be provided independently, and can be replaced by bending the end of either the vertical pipe 2a, the horizontal pipe 2b, or the axial pipe 2c. Sometimes. Note that the support frame 2 is attached to the upper horizontal pipe 2.
It has a rectangular shape that has been deformed so that the vertical pipe 2a side of b is higher, and the length of the vertical pipe 2a is longer than the length of the upper and lower shaft pipes 2c, 2c plus the length of the support described later. It is made.

The pillar 3 has a slight protrusion 3a on the upper and lower parts of the two main pillars.
, 3a are connected by a figure-8-shaped connector made of synthetic resin or clamping tools 3b, 3b made of metal, and on one side of the figure-8-shaped connector or clamping tool 3b made of metal, there are two Two auxiliary protrusions 3c, 3C having approximately the same height and the same outer diameter as the protrusions 3a, 3a are provided, and the supporting frame 2 is rotatably fitted into each of the upper and lower shaft tubes 2C12C, respectively. be done.

As shown in FIGS. 2 and 3, the holding rod 5 has a substantially U-shape with both ends of a steel pipe bent to one side, and is connected to the upper and lower horizontal pipes 2b.
, 2b, upwardly directed protrusions 2f, 2
f, and maintains the distance or opening angle α between adjacent support frames 2 constant. A plurality of the protrusions 2f, 2f are provided, and by selecting one with which the holding rod 5 fits, the distance or the opening of the adjacent support frames 2 can be adjusted as shown by the two-dot chain line in FIG. This is done so that the angle α can be adjusted to some extent. Further, the relationship between the holding rod 5 and the protrusions 2f, 2f is not necessarily limited to this embodiment.
Instead of f and 2f, small holes may be formed and the holding rod 5 may be fitted into the small holes. In this case, it is preferable to provide a seal to prevent rainwater from entering the small hole.

Thus, the substantially C-shaped support frame 2 is constructed such that the shaft tubes 2c, 2c fit into the outer surfaces of the protrusions 3a, 3a or the auxiliary protrusions 3c, 3c, and are rotatable relative to the support column 3. .

Note that the support column 3 is not essential, and instead of the axial tube 2c of the support frame 2, a vertical tube 2a is used, and the entire frame is approximately rectangular.
It is also possible to omit it by connecting with a letter-shaped connector. In addition, the dimensions of the vertical tube 2a and horizontal tube 2b vary depending on the use, but when used as a golf practice net, the length of the vertical tube 2a is shortened to about 2.5 m, and when used as a sun drying net, the vertical tube 2a is shortened to about 1.5 m. use something The tube diameter is about 25 to 35 mm.

Generally, the net 4 is tied to the pipe material constituting the support frame 2 described above with a thin row 16, but a hook is provided in advance to engage the net 4, and the hook 2d is engaged with the net 4. It is also possible to In addition, the net 4 is used for each support frame 2 as shown in FIG. 1 in a golf net.
Each frame is stretched in a rectangular shape, and further stretched between the upper surfaces of adjacent support frames 2, and the hook 2d is used to suspend a hanging membrane 7 that receives a golf ball. 8 is a stand on which the golf ball is placed.

According to this embodiment, in order to install the portable net, first, each support frame 2 is assembled, the net 4 is stretched thereon, and the support frame 3 is fixed to the shaft. This allows the whole to be constructed three-dimensionally. Next, open each support frame 2 slightly narrowly and open the adjacent support frame 2.
A net 4 is stretched over the top of the screen, and a banner 7 is further hung. After that, each support frame 2 is expanded around the support 3 to remove slack in the net 4 or hanging curtain 7, and in this state, both ends of the holding rod 5 are fitted to the protrusions 2f, 2f to adjust the distance between the support frames 2, Alternatively, the opening angle α is fixed and the assembly is completed.

This assembly method is not limited to this method, but each net 4 or banner 7 is installed between each support frame 2 in advance, then stood up, and after each support frame 2 is expanded, the slack is removed, and the holding rod 5 is It may be fixed.

〔Effect of the invention〕

As described above, in the assembly structure of the portable net according to the present invention, a plurality of substantially rectangular support frames 2 made by bending pipe materials are attached to the vertical axis (the protrusion 3a) on their negative side. ,
3a or auxiliary projections 3c, 3c), a net is stretched between adjacent support frames, and a holding rod is provided to maintain a constant distance between adjacent support frames. Therefore, after assembling the portable net 1, the slack in the net can be relatively easily removed by unfolding the adjacent support frames 2 to the left and right, and the slack in the net can be removed relatively easily. Since it is fixed by the holding rod 5,
Even if the banner 7 having a target is hit by a ball and a strong tension is temporarily generated therein, the left and right support frames 2 will not come close to each other, thereby achieving the effect of achieving the object of the present invention.
