DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip for attracting plant stems such as tomatoes, eggplants, cucumbers, melons and sweet peppers by hanging them on strings suspended from above.

[0002]

2. Description of the Related Art Stalks of seedlings such as tomatoes, eggplants, cucumbers, melons and peppers grow upward as they grow. However, in order to save labor and removal, and to reduce costs, in recent years, a guide line has been dropped from above to stop the stem at the guide line. Various proposals have been made on how to stop it. There is a method in which the string for invitation is wound directly on the stem. However, if the string for invitation is wound on the stem, there is a problem that it takes time to unwind the string when disposing the stem at the time of harvesting.

In Japanese Patent Publication No. 5-15405, as shown in FIGS. 5 and 6, sandwiching pieces 10 and 20 each having a semicircular beak at one end and an operating portion at the other end are provided with a sandwiched bulging center.

A slit 25 for introducing the guide wire 4 into the front part of the middle abdomen 23, a concave part 26 in which the support groove 24 traversing the slit 25 is locally deepened from the inner wall surface of the slit 25,
A projection 14 provided on the holding piece 10 was provided so as to normally enter the recess 26 and hold the inducing line, and the two operating sections were brought together against the spring to enter the holding piece 20 side. Convex part 14 of sandwiching piece 10 and shielding plate 15
However, there is disclosed a tying device for an inducing line of a plant stem which turns around the eccentric fulcrum shaft 1 to create a gap for introducing the external inducing line 4 into the slit 25 (the reference symbol in the figure denotes a symbol). , The same as those described in the publication).

[0004] However, this tying member requires three parts, two sandwiching pieces and a spring, and the assembly cost of the product is also high. For general greenhouse horticulture farmers, 150,000 per house
Approximately 00 must be used, and the burden on farmers is large in terms of cost and labor, and it is not widely used. In addition, since the thickness of the string passing through the slit 25 is limited, when a thick string is used at the time of attraction, a gap is formed at the tip of the stem pinching portion and the string cannot be completely closed, or the string itself may be pinched. There are things you can't do. The same applies to the stem clip described in Japanese Unexamined Utility Model Registration No. 3018081.

When using this conventional clip, as shown in FIG. 8, the stem 39 and the attraction string 40 are simultaneously supported by one hand, and the clip is held by the fingers of the other hand on the first holding piece 31 and the second holding piece. When trying to approach the attraction string 40 while holding the holding piece 32 in an open state, the claw 38 is already closing the hinge portion 33 and the gap is narrow.
Great care must be taken to put it inside the 8. In particular, many farmers have elderly people and many have poor eyesight, and such tasks that require attention are burdensome. Since this work requires as many as 15,000 pieces per house, instruments that require such labor and attention are:
Not adopted at all.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below based on embodiments shown in the drawings. FIG. 1 is a plan view showing an embodiment of the present invention, FIG. 2 (a) is a front view, and FIG. 2 (b) is a sectional view taken along the line AA of FIG. In the figure, 1
Is a first holding piece having a stem supporting portion 1a, 2 is a stem supporting portion 2a
The second holding piece 3 having a thin hinge portion that connects the two holding pieces 1 and 2 flexibly. At the base of the first holding piece 1, an inner string holding portion 1b is formed.
At the base of the holding piece 2, an outer string holding portion 2b is formed. A flexible lock portion 1c having an engagement protrusion 1d is formed at a distal end portion of the first holding piece 1, and an opening 2c through which the lock portion 1c passes is formed at a distal end portion of the second holding piece 2. An engagement portion 2d with which the engagement protrusion 1d is engaged is formed. Claws 1e and 2e for protecting the hinge portion 3 so that the string does not enter further inside are formed on the base end sides of the inner string pinch portion 1b and the outer string clip portion 2b. The inner string pinching portion 1b and the outer string pinching portion 2b are each composed of two upper and lower plate-like components.
2f, the former can bend inward and the latter can bend outward, so that the string can be pinched whether the diameter of the string is small or large. It has become. In addition, 1g and 2g are knobs formed for the purpose of easy holding when the first holding piece 1 and the second holding piece 2 are bent. In addition, the outside of the outer string pinching portion 2b is provided with a non-slip to make it easier to hold when performing work. Further, the lock sloped portion 1h is recessed so that it is easy to press with a finger when releasing the lock.

When the lock is pushed and released, the stem support portions 1a,
The semicircular portion 2a can be removed only by bending the lock portion 1c without bending. Also, the stem support portions 1a, 2a
There is a tongue piece 1j so that the lock does not easily come off during work or the like due to deformation or displacement of the semicircular portion.

The claws 1e and 2e protect the hinges so that the strings do not hang on the hinges due to the weight of the stems when the stems are pulled and the stems are attracted. It is also a positioning mechanism for bending the hinge part from the center when bending the hinge part with the string in between, so that the lock part is securely locked.

Further, a radius is provided so that the attracted stem does not damage the inside of the stem supporting portions 1a and 1b of the clip.

FIG. 3 is a process diagram showing a state in which work is performed using the string invitation clip of this embodiment. (A) is a state in which the string inviting clip is bent from the state of FIG. 1 with the thumb and the index finger or the middle finger, holding the knobs 1g and 2g, and the string 4 and the stem 5 are to be sandwiched. Since the string inviting clip exerts a restoring force to open in a natural state, the clip can be operated with one hand by pinching the knobs 1g and 2g at an appropriate angle with the fingers of one hand. The other hand supports the stem 5 and the string 4 so that the stem 5 is positioned between the stem supporting portions 1a and 2a, and the string 4 is connected to the inner string pinching section 1b and the outer string pinching section 2b.
When the knobs 1g and 2g are sandwiched so as to be located somewhere in between, the stem 5 becomes the stem support 1 as shown in FIG.
a, 2a, the string 4 is sandwiched between the inner string sandwiching portion 1b and the outer string sandwiching portion 2b. In addition, 1g, 2g of knobs
, The lock portion 1c enters the inside of the opening 2c, and finally the engagement protrusion 1d engages with the engagement portion 2d, and the engaged state is maintained even when the finger is released. When removing the cord inviting clip, the distal end portion of the lock portion 1c is pushed so that the engagement protrusion 1d is separated from the engagement portion 2d.
The first holding piece 1 and the second holding piece 2 are opened by the restoring force, and the stem 5 and the string 4 can be removed.

When the string 4 is pulled strongly, the string 4 moves to some extent in the lateral direction between the inner string pinching portion 1b and the outer string pinching portion 2b. However, as shown in FIG. Since it is prevented from reaching the portion 3, it is possible to protect the thin hinge portion 3 from being pulled and cut by the string 4.

FIG. 4 is a sectional view taken along line BB of FIG. 3C.
As shown in the figure, the inner string pinching portion 1b and the outer string pinching portion 2b are each composed of upper and lower two plate-shaped components, and have gap portions 1f and 2f, respectively. Can be bent inward, and the latter can be bent outward, so that the string can be pinched whether the diameter of the string is small or large.

[0016]

As described above, according to the present invention, the following effects can be obtained. (1) Significant cost reduction can be achieved. The conventional cord-inducing clip shown in FIGS. 5 and 6 is composed of a single product by assembling a plurality of parts, and is expensive. However, since the clip of the present invention is integrally molded, no parts and assembly are required. Not required.

(2) Even if the diameter (thickness) of the string varies, the string can be reliably attracted. The conventional clips shown in FIGS. 5 and 6 are sold by specifying a string. When a string having a large diameter is used at the time of attraction, a gap may be formed at the tip of the stem pinching portion and the string may not be completely closed, or the string itself may not be pinched. Since the clip of the present invention has a structure in which the string clipping portion has elasticity even when the diameter of the invitation string is varied, the string is securely bitten. Also, the lock part is at the tip of the stem pinching part,
Since the lock is locked, even if the diameter of the invitation string becomes large, there is no gap formed with the stem pinching portion open as in the conventional product.

(3) It is possible to cope with an attraction method other than the general string attraction. The product of the present invention can be attracted by sandwiching the horizontal string and the stem at a place where the horizontal string and the stem intersect, in addition to the general string inducing method because the length of the string sandwiching portion is long. The conventional clip cannot cope with a wide string or the like.

(4) No damage to the stem. In the conventional product, the stem grew thick during the attraction, and when the clip was removed, the opening of the stem pinching portion was not fully opened. Sometimes, when the clip was removed from the stem, the stem or the branch was broken, and the clip was removed from the narrow part of the stem. In the clip of the present invention, the first and second holding pieces are wider than the inner diameter of the stem pinching portion, and the stem is not damaged when the clip is removed from the diameter because the clip is fully opened.

(5) In the one-piece clip shown in FIGS. 7 and 8, the nail is trying to close the hinge portion, and the gap is narrow. Therefore, it is necessary to pay close attention to inserting the string inside the nail. Although the burden is particularly large for the elderly, the string-holding portion of the present invention is sufficiently long, so that the operation of holding the string can be easily performed, and the work can be performed easily and quickly.
