Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a binding device that can be attached with one touch to a guide line hanging from above midway through the stems of long seedlings such as cucumbers, tomatoes, melons, etc.

<Conventional technology> The stems of cucumber, tomato, and melon seedlings grow upward as they grow. This stem is dead weight,
In order to prevent the seedlings from becoming unable to bear the weight of the fruit and falling down mid-way, conventional methods have been to hang an attracting line from above along the seedling, tie the stem to the attracting line with a string, or tie the stem to the attracting line. The wires are tied together by wrapping them with adhesive tape.

<Problem to be solved by the invention> This tying operation must be performed every time the seedling grows and the stem extends upward to a certain extent. Moreover, as the stems grow, they become thicker, so if the string or tape that was previously bound gets stuck in the thicker growing stems, the tubes running inside the stems are tightened, which impedes the growth of seedlings and fruits. To prevent the fruit from slowing down or becoming stressed, it is necessary to remove all previously tied strings and tape and tie them again to accommodate the growing and thickened stem.
Binding work is very time consuming.

<Means for Solving the Problems> Therefore, the present invention is a tying tool that can be tied with one touch and does not need to be tied again even when the stem grows and thickens. scissor pieces 10, 20 having a beak and an operating part at the other end;
A binding tool that fits the middle part of the scissor piece 10 into the internal support groove 24 of the intermediate abdomen 23 of the scissor piece 20 that bulges out to the center, combines it into a symmetrical clothespin, and attaches it to a hanging soft pull line. A fulcrum shaft 1 for opening and closing both scissors pieces provided near the back of the middle part of the scissors piece 10, a spring that passes through a long hole in the operation part of both scissors pieces and presses the back side of both beaks, A beak matching step provided on the distal end surface of the beak, a flexible shielding plate 15 extending from the beak base of the scissor piece 10 so as to touch and follow the inner surface of the beak of the scissor piece 20, and an inner peripheral surface of the beak of the scissor piece 20. A slit 25 for introducing the guiding wire 4 into the front part of the intermediate abdomen 23 from the rear end, and a slit 2
A slit 25 is formed locally in the support groove 24 that crosses the
The scissor piece 10 is provided with a concave portion 26 deepened deeper than the inner wall surface thereof, and a convex portion 14 provided on the scissor piece 10 so as to enter into the concave portion 26 and hold the guide line 4 in its mouth during normal operation. By bringing them together, the protrusion 1 of the scissor piece 10 that had entered the scissor piece 20 side can be removed.
4 and the shielding plate 15 rotate around the eccentric fulcrum shaft 1 to create a gap for introducing the external guide line 4 into the slit 25.

(Example) In the illustrated example, 10 is a movable scissor piece;
20 is a fixed scissor piece, and both pieces 10, 20 are molded from plastic.

The movable scissor piece and the fixed scissor piece each have semicircular arc-shaped beaks 11 and 21 at one end, and operating parts 12 and 2 at the other end.
It has 2. The fixed scissor piece 20 has a bulging abdomen 23 in the middle, and a support groove 24 into which the middle part 13 of the movable scissor piece 10 fits is provided in the abdomen.

The middle part 1 of the movable scissor piece 10 is inserted into this support groove 24.
3 is fitted, and the upper wall 23a and lower wall 23b of the abdomen, and the intermediate portion 13 of the movable scissor piece located therebetween, are pivoted in a clothespin type with a series of fulcrum shafts 1. In this embodiment, there are elongated holes 12' at the bases of the operating parts 12 and 22 of the movable scissor piece and the fixed scissor piece.
A C-shaped biasing spring 2 is passed through 22', one end of the spring 2 is connected to the back of the beak 11 of the movable scissor piece, and the other end is connected to the back of the beak 21 of the fixed scissor piece. The beaks 11 and 21 at one end of the movable scissor piece and the fixed scissor piece are closed in an annular manner, and the operating parts 12 and 22 at the other ends of both pieces 10 and 20 are opened in a V-shape (Figs. 1 and 2). (see figure). In this state, when the operating part 12 of the movable scissor piece is brought close to the operating part 22 of the fixed scissor piece with a finger against the elasticity of the biasing spring 2 (arrow in FIG. 3), the movable scissor piece 10 moves around the fulcrum shaft 1. rotates, and the biasing spring 2
The movable scissor piece beak 1 moves through the long hole at the base of 2.
1 opens apart from the beak 21 of the fixed scissor piece.

Upper wall 23a and lower wall 2 of the abdomen of the fixed scissor piece 20
3b is provided with a series of slits 25 that extend halfway from the beak 21 along the bottom 24' of the support groove 24 toward the operating section 22, and at the same time, the bottom 24' of the support groove 24
4', a recess 26 that opens toward the intermediate portion 13 of the movable piece is located at the back of the slit 25.
is provided. Correspondingly, the intermediate portion 13 of the movable piece 10 is provided with a convex portion 14 that fits into the concave portion 26.
will be established.

As mentioned above, when the beaks 11 and 21 of the movable scissor piece and the fixed scissor piece close in an annular shape due to the elasticity of the biasing spring 2, the convex portion 1 provided on the intermediate portion 13 of the movable scissor piece closes.
4 enters the recess 26 of the fixed scissor piece, and the abdomen 13
A series of slits 25 in the upper wall 13a and lower wall 13b are cut off (see FIG. 4). Also, biasing spring 2
When the movable scissor piece is rotated against the elastic force of the movable scissor piece and the beak 11 of the movable scissor piece is separated from the beak 21 of the fixed scissor piece and opened, the protrusion 14 escapes from the recess 26 (see FIG. 3).

To use, as described above, rotate the movable scissors piece with your fingers against the elasticity of the biasing spring 2 to bring it into the state shown in FIG.
The stem 3 is placed between the beaks 11 and 21, and the attracting line 4 is placed in the slit 25 and positioned deep therein (see the broken line in Figure 3), and then the stem 3 is placed between the beaks 11 and 21 (see the broken line in Figure 3). release the power. As a result, the movable scissor piece 10 is rotated in the opposite direction by the elasticity of the biasing spring 2, and the beaks 11 of both scissor pieces 10 and 20 are rotated in the opposite direction.
and 21 close in an annular shape, confining the stem 3 in the annular space, and the convex part 14 of the movable scissor piece enters the concave part 26 of the fixed scissor piece, and the fourth
As shown in the figure, bend it into a crank shape and sandwich the guide line between it and the bottom of the recess 26. Therefore, the stem 3 can be attached at a predetermined height level of the guide line 4 to support the middle of the stem 3 against the guide line, and since the guide line 4 bends like a crank, it does not move along the guide line.

When opening the beaks 11 and 21 and guiding the stem 3 and attraction wire 4 between them, and inserting the attraction wire 4 into the slit 25,
Shielding plate 1 to prevent stems from entering the slits
5 is provided on the movable scissor piece 10. Also, beak 11
and 21 are provided with interlocking step portions 11' and 21', and when the beaks 11 and 21 are closed annularly, the interlocking step portions 11' and 21' fit into each other. The thickness of the attraction line 4 sandwiched as shown in the figure,
Even if the tips of the beaks 11 and 21 are slightly separated depending on the degree of pinching, the mouth will not open.

Note that the beaks 11 and 21 need only be able to confine the stems 3 in the space with ample space between them, so they do not need to be semicircular in the precise sense, and may be semielliptical or U-shaped. But that's fine.

<Effects of the Invention> The binding device of the present invention guides the stem 3 and the attraction line 4 between the beaks 11 and 21 that open against the biasing spring, inserts the attraction line deep into the slit 25, and connects the movable scissors piece. 10
By simply releasing the force applied to the stem, it can be attached to the attraction line and the stem can be supported along the attraction line. Therefore, the tying work can be done with one touch, and you are freed from the trouble of tying with string or wrapping with tape.

Furthermore, since the stem 3 is confined in the space formed between the beaks 11 and 21 which are closed while facing each other,
You can freely grow the seedlings until there is no space left, and once the seedlings have grown to the point where there is no space left, you can simply reattach the thin part of the stem a little higher to support it, and then cut the string or tape and retie it. This eliminates the hassle and waste of wrapping and re-wrapping. The binding tool of the present invention has the following appearance:
Although it is bilaterally symmetrical, its fulcrum axis 1 is at an eccentric position away from the axis of symmetry, so when holding the stem 3 and attraction line 4 in your mouth, when you open both beaks 11 and 21 as shown in Figure 3, the inner surface of beak 21 The shielding plate 15 that was along the line lifts up and separates to open an introduction path for the guide line 4. Furthermore, if the tip of the shielding plate 15 is inserted between the stem 3 and the guide wire 4 in this state, even if the two are entangled, they can be easily separated and only the guide wire 4 can be introduced into the slit. . In addition, if both scissor pieces are left half-open, they can move up and down along the attraction line and adjust the binding position of the stems up and down, and at the same time, the attraction line is blocked by the shielding plate and comes out of the slit. This makes adjustment work easier.

Since the tying tool of the present invention holds the attracting line in its mouth at a position close to its center of gravity, even if the attracting line is a string with no rigidity, it will hang horizontally and there is no risk of damaging the stem.

Furthermore, since the tow line is bent into a crank shape as shown in Fig. 4, there is no fear that the binding tool will slide along the tow line in a rainstorm.
