Description

[Detailed Description of the Invention] This invention mainly involves the use of nets that are used to cover the entire fruit tree field from a high place so as to cover each tree so as to prevent the fruits and berries from being damaged by crows, insects, etc. The purpose is to provide an insect- and bird-proof net that is easy to attach, can be stretched under tension, and is easily removed when unnecessary, such as in winter.

Traditionally, pears and other fruits are covered with a paper bag from the time they ripen to prevent bird damage, but in recent years, as the fruit is required to have a high sugar content, more direct sunlight is required. However, paper bags could no longer be used, so instead of paper bags, entire fruit fields were covered with netting to protect the ripening fruit from bird damage.

However, fruit fields are generally wide, measuring between 30 and 50 are, and a frame with a height of 4 to 5 m is built and the ceiling and sides are covered with netting, but the netting on each side is very wide. Since the net is thick and needs to be removed during the winter, hooks used for curtains are installed on both sides of the net on each side, and the net is attached to each side by passing it through a wire stretched along the frame. However, not only is the operation cumbersome,
Because it loosens in the middle, the ceiling screen, the side screen, and the adjoining nets on both sides must be connected with string or tied at appropriate intervals, making attachment and removal extremely troublesome. It was something.

This invention eliminates these drawbacks, and embodiments thereof will be described with reference to the drawings.

FIG. 1 shows the insect and bird net of the present invention stretched over a frame 19 standing in a field. ．． 5, and as shown in FIG. Both side surfaces 3 and 5 are each composed of a pair of sub-nets 7 formed separately from a main net 6, and slide fasteners are provided at both ends of the main net 6, that is, along the entire length of both ends extending from the ceiling surface 1 to both sides 2 and 4. One fastener stringer 8, 9 is attached, and the other fastener stringer 10, 11 is attached to the outer periphery of each subnet 7, 7 except for the lower side, and both opposing fastener stringers 8, 10 and A pair of sliders 1 between each of 9 and 11
2, 13, 14, and 15 are inserted so that their rear parts face each other.

Note that there is no clasp at the end of each fastener stringer 8 to 11, and the sliders 12 to 15 can be freely inserted therein, for example, by attaching a draw pin or box pin 16, 16 of a fastener with a releasable fitting, or Alternatively, a synthetic resin film is attached to maintain rigidity.

Further, an entrance/exit 18 is provided on the side surface of the main and subnets 6, 7, which is opened and closed by a slide fastener 17.

3 and 4 show a state in which the net according to the present invention is stretched on a frame 19. At this time, a reel 20 is provided on the side of the frame 19, and a main net 6, a pair of sub-nets 7, 7 are arranged in a row and wound around each other, and each slider 12 to 15 is removed when not in use.

However, as shown in FIG. 5, the sliders 12 to 15 may be inserted and wound around the reel 20 by threading.

In the example shown in FIG. 6, several slide fasteners 21 to 25 are arranged in an H shape on the ceiling surface 1, and the ceiling surface 1 is formed to be openable.

In each of the illustrated embodiments, the slide fasteners connecting the main and subnets 6 and 7 are provided at the corners of the frame 19, but they may also be provided at positions close to the corners. I can do it.

This invention has the above structure, and when the main and subnets 6 and 7 wound around the reel 20 are stretched on the frame 19 as shown in FIG. First, the main net 6 and both sub nets 7, 7 are wound and twisted from the reel 20, and the opposing fastener stringers 8, 10, 9,
110 Align the tips and insert a pair of sliders 1 from the tips.
2, 13, 14, and 15 with their rear parts aligned, insert the following sliders 13, 15 by a length approximately equal to the height of the side surfaces 3, 4, and 5, and then insert them as shown in FIG. 《The main net 6 is guided to the ceiling surface of the frame 19, and then the sliders 13 and 15 inserted previously are fixed to the corners of the frame 19 by appropriate means, and the Σ main net 6 is moved to the position of the reel 20. When pulled from the opposite side, both fastener stringers 8, 10, 9,
11 are sequentially engaged and closed, the main and sub-nets 6 and 7 are integrated and placed over the frame 19, and when both the sub-nets 7 and 7 completely cover the sides of the frame 19, the ceiling surface of the main net 6 1 also covers the ceiling surface of the frame 19, by hanging down the sides 2 and 4 of the main net 6 and then sliding each slider 12 to 15 downward, the entire surface of the frame 19 can be covered with the net. It is something.

As shown in Fig. 5, if the sliders are installed in advance, insert the sliders 12 and 14 deeply as shown by the chain lines to open the sides 3, 4, and 5, and then cover them in the same manner as described above. It is.

In addition, when the insect/bird net is no longer needed, each slider 12 to 15 is moved to the upper corner of the frame 19 and the sides are divided, and then the sliders 13 and 15 near the reel 20 are temporarily fixed. When the main and subnets 6, 7, and 7 are wound onto the reel 20, the sliders 12 and 15 remain in the frame 19, and the main and subnets 6, 7 are separated and removed.

As shown in Fig. 6, slide fasteners 21~
25, each slide fastener 21
25 are opened, the ceiling surface 1 is removed and placed, and each slide fastener 21 to 25 is closed again when necessary.

As described above, the insect-proof and bird-proof net according to the present invention consists of main and sub-nets, which are connected by a slide fastener having a pair of sliders, so that the main and sub-nets can be connected as necessary. This can be done over a portion or the entire length, and since they are connected sequentially when pasting, it is very easy to do even if it is a wide piece.

In addition, since they are connected with slide fasteners, they are tensioned evenly over their entire length, so there is no risk of wrinkles forming in some areas and creating shadows, and there is no possibility of crows or insects getting in through the joints.

Furthermore, since it is made up of a main net and a sub-net, it is possible to partially replace a fallen net in the event of damage, and it can also be easily converted to a net with a different mesh if necessary. It is possible to do so, and of course it is easy to remove the whole thing.
