Description

[Detailed description of the invention] This invention relates to a structure for attaching a wire mesh to the side of a court for platform tennis, which is a short-handled racket called a padel and is played with a rubber sponge ball according to the same rules as tennis. .

Courts for platform tennis are made into a unit that includes wire mesh and a court stage, and can be installed on rough or sloping areas, and are 1/3 to 1/4 the size of a tennis court. The present invention relates to a structure in which a wire mesh is attached to repel a competition ball on a court for such a new sport, ie, platform tennis.

Embodiments will be described below with reference to the accompanying drawings. Play is played on the upper surface of the floor, with posts 1 and 1 erected in the center, and a net 2 stretched between them. Floor F is surrounded by wire mesh 3 on all sides. The wire mesh 3 includes an upper mesh frame 4, a lower mesh frame 5, and supports 6 bolted at regular intervals between these mesh frames.
...is obsessed with...

The floor F is constructed by welding a plurality of floor plates f... onto the upper beam 7. The upper beam 7 is fixed on the lower beam 8 by welding, and this lower beam 8 is fixed on the foundation 9 about 90 cm above the ground by, for example, a wire. Reference numeral 10 designates a snow gate which is pivotally attached to the lower part of the pillars 6, 6 with pins 11. Reference numeral 12 denotes a door provided at the center of the side, which is hinged to the support column 6. 13 is a staircase.

Referring to Figures 4 to 6, Snow Gate 1
0 is a gate plate mounting frame 10b made of lauan material 10a, etc.
It is attached with screws 10c. A support shaft 1 is attached to the upper part of the gate plate mounting frame 10b via a collar 12.
1 is inserted, and the support shaft 11 is rotatably supported by the support column 6.

13 is a door that is hinged to the post 6. 14 is a staircase, which you can go up and down and open and close the door to enter and exit the court. 15 (FIGS. 6 and 11) is a tensioner which applies tension to the wire mesh 3, and the tension can be adjusted by turning a nut 15a. 16 is the corner piece for the upper mesh frame,
This reinforces the corners of the upper mesh frame.

The present invention relates to a structure for installing side wire mesh in the above-mentioned platform tennis court. Conventionally, a flat bar 17 with holes 17a as shown in FIGS. 7 and 8 was used as a wire mesh 3.
The end mesh was sewn through and fixed to the upper and lower mesh frames 4 and 5 with tapping screws 18.
With this method, to attach it all around the court, it takes all
There were problems in terms of workability, as there were 1,000 locations and work was required at heights.

This invention is an improvement on the known mounting structure, and is
As shown in the figure, a round steel or pipe 19 is tied to the end of the wire mesh 3 with a wire 20, and this round steel or pipe 1
9 is hooked onto a plurality of hooks 21 attached to the upper and lower screen frames 4 and 5, and pulled from the bottom using a tensioner.

FIG. 11 shows details of the tensioner 15. 2
Reference numeral 2 denotes a spring case, which has a square cross section and has a top plate 23 at one end with an insertion hole 22a for a bolt 15b.
is fixed. A coil spring 24 is installed inside the spring case 22, and this coil spring is sandwiched between a top plate 23 and a reinforcing plate 25, and can be compressed by turning a nut 15a. Reference numeral 26 denotes a rectangular reinforcing plate, in which an insertion hole 26a for a bolt 15b is bored at an eccentric position.

As shown in FIG. 6, the tensioner 15 is attached by passing bolts 15b through the lower mesh frame 5 and then fixing the spring case 22 to the support by welding. Therefore, the nut 15a is inserted into the spring 2 from below.
4, the bolt 15b is pulled. Then, the tension of the net can be adjusted by pulling the lower net frame 5 through the square reinforcing plate 26.

According to the structure described above, 1) If the pipes and the net are connected at the factory, the net can be attached with one touch at the site, so the assembly work time can be greatly reduced. 2) Since no power tools are used, work can be done even in rainy weather. 3) Even if the wire mesh becomes rusty and you want to replace it, it is extremely easy to replace because you just hook it on. 4) After the wire mesh is attached, a tensioner is used to apply tension to the wire mesh from below through the lower mesh frame, but the mesh does not come off and tension adjustment is easy.
