Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a clip that attracts plant stems such as tomatoes, eggplants, cucumbers, melons, and peppers by holding them on a string suspended from above.
[0002]
[Prior art]
The stems of seedlings such as tomatoes, eggplants, cucumbers, melons and bell peppers grow upward as they grow, so traditionally they set up splints to prevent the stems from falling down due to their own weight or fruit weight. In order to save costs and the cost of removal, in recent years we have drawn down an attracting line from above and stopped the stem at the attracting line. Various proposals have been made on how to stop it.
Although there is a method of winding the invitation string directly around the stem, there is a problem that when the invitation string is wrapped around the stem, it takes time and effort to dispose of the string when the stem is disposed at the time of harvest.
[0003]
In Japanese Patent Publication No. 5-15405, as shown in FIG. 5 and FIG. 6, pinch pieces 10 and 20 having a semi-arc-shaped hook at one end and an operation part at the other end are provided. A binding tool that fits the middle part of the clip piece 10 into the inner support groove 24 of the intermediate abdomen 23, is combined in a symmetrical clothespin shape, and is attached to a soft attracting wire that hangs down. From the springs that push the back of both scissors through the long holes of both scissor piece operation parts provided near the back, the mating step provided on both scissors tip surfaces, and the scissors base of the scissors 10 A flexible shielding plate 15 extending so as to be in contact with the inner surface of the heel of the piece 20, and a slit 25 for introducing the guide wire 4 that has entered the front portion of the intermediate abdomen 23 from the rear end of the inner peripheral surface of the ridge of the sandwich piece 20. The support groove 24 across the slit 25 is locally located behind the inner wall surface of the slit 25. A deepened concave portion 26 and a convex portion 14 provided on the pinching piece 10 so as to be inserted into the concave portion 26 and sandwich an attracting line at all times, and the two operating portions are brought together against the spring to thereby hold the pinching piece The stalk of the plant in which the convex part 14 and the shielding plate 15 of the pinch piece 10 that has entered the 20 side turn around the eccentric fulcrum shaft 1 to create a gap for introducing the external attracting line 4 into the slit 25. A binding tool for the attraction line is disclosed (the reference numerals in the figure are the same as those described in the publication).
[0004]
However, this binding tool requires three parts, two pinching pieces and a spring, and the assembly cost of the product is also high. A general facility horticultural farmer has to use about 15,000 pieces per house, and the farmer's burden is large in terms of cost and labor, and is not widespread. In addition, since the thickness of the string passed through the slit 25 is limited, when using a string with a large diameter at the time of attraction, a gap may be formed at the tip of the stalk pinching portion, and the string itself may not be closed. There are things that cannot be done. The same applies to the stem clip described in the actual registration No. 3018081.
[0005]
FIG. 7 shows the only known example of a conventional monolithic citation clip. FIG. 7A is a plan view, and FIG. 7B is a front view. In this conventional example, a semi-circular first sandwiching piece 31 and a second sandwiching piece 32 are coupled by a strip-shaped thin-walled hinge portion 33, and the second sandwiching piece 32 has an engaging projection 35. A flexible lock portion 34 is formed, and an engagement portion 37 in which an opening 36 through which the lock portion 34 penetrates and an engagement projection 35 are engaged is formed at the distal end portion of the first clamping piece 31. . And the nail | claw 38 for pushing an attracting string into the hinge part 33 is formed.
[0006]
When the clip of this conventional example is used, as shown in FIG. 8, the stem 39 and the attracting string 40 are simultaneously supported with one hand, and the clip is held with the fingers of the other hand, the first holding piece 31 and the second holding piece 32. The nail 38 is already trying to close the hinge portion 33 when it tries to approach the attracting string 40 while holding it in an open state, and since the gap is narrow, it is difficult to insert the string 40 inside the nail 38. Caution must be taken. In particular, the farmer has many elderly people and many have poor vision. Therefore, work requiring such attention is burdensome. Since this work requires 15,000 pieces per house, such an instrument that requires labor and attention is hardly adopted.
[0007]
[Problems to be solved by the invention]
The problem to be solved by the present invention is to provide a plant stem invitation clip that is an integral clip and that is very easy to attach to the stem and the invitation string.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the plant stem citation clip of the present invention connects a first sandwiching piece and a second sandwiching piece, each having a semicircular stem support part for supporting a stem, by a hinge part, and In a plant stem invitation clip in which a lock portion for holding the holding pieces in a closed state is formed at the tips of the holding pieces and the second holding pieces, an attracting cord is connected to the base portions of the first holding pieces and the second holding pieces. An inner string pinching portion and an outer string pinching portion that are tightened in a bent state are formed respectively.
In this plant stem citation clip, the lengths of the inner and outer string holding portions are approximately the same as the lengths of the stem support portions of the first holding piece and the second holding piece.
A knob portion is formed on the outside of the stem support portion of the first sandwiching piece and the second sandwiching piece for preventing the finger from slipping.
Anti-slip is formed on the surface of the outer string pinching portion.
The inner string pinching portion and the outer string pinching portion can be formed by two upper and lower plate-shaped components, and a gap is provided in the upper and lower plate-shaped components to bend in the thickness direction of each plate. Like that.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described based on examples shown in the drawings.
FIG. 1 is a plan view showing an embodiment of the present invention, FIG. 2A is a front view, and FIG. 1B is a cross-sectional view taken along line AA of FIG. In the figure, 1 is a first holding piece having a stem support portion 1a, 2 is a second holding piece having a stem support portion 2a, and 3 is a thin-walled hinge portion connecting both the holding pieces 1 and 2 so as to be bent. is there. An inner string pinching portion 1 b is formed at the base of the first holding piece 1, and an outer string pinching portion 2 b is formed at the base of the second holding piece 2. A flexible lock portion 1c having an engaging projection 1d is formed at the distal end portion of the first sandwiching piece 1, and an opening 2c through which the lock portion 1c passes is formed at the distal end portion of the second sandwiching piece 2. An engaging portion 2d that engages with the engaging protrusion 1d is formed. Also, claws 1e and 2e are formed on the base end side of the inner string holding portion 1b and the outer string holding portion 2b to protect the hinge portion 3 so that the string does not enter further inside. In addition, the inner string pinching part 1b and the outer string pinching part 2b are each composed of two upper and lower plate-shaped components, each having gaps 1f and 2f, and the former can be bent inward. The latter can be bent outward, so that the string can be clamped regardless of whether the string is thin or thick. In addition, 1g and 2g are knobs formed for ease of holding when the first sandwiching piece 1 and the second sandwiching piece 2 are bent. Further, the outer side of the outer cord pinching portion 2b is provided with a slip stopper so that it can be easily held when working. Further, the lock portion gradient portion 1h is recessed so that it can be easily pressed with a finger when the lock is released.
[0010]
When the lock is pushed and removed, the semicircular portions of the stem support portions 1a and 2a are not bent and can be removed only by bending the lock portion 1c. In addition, 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 portions of the stem support portions 1a, 2a.
[0011]
The claws 1e and 2e protect the hinge portion so that when the stem is attracted by holding the string, the hinge portion protects the hinge portion so that the string is hooked on the hinge portion and the hinge portion is not overloaded. This is also a positioning mechanism for ensuring that the hinge portion is bent from the center and the lock portion is securely locked when the hinge portion is bent.
[0012]
Furthermore, it is rounded so that the attracted stem may not be damaged inside the stem support portions 1a and 1b of the clip.
[0013]
FIG. 3 is a process diagram showing a state in which the work is performed using the string invitation clip of the present embodiment. (A) is a state in which the string 4 and the stem 5 are about to be sandwiched by folding the present string invitation clip from the state shown in FIG. Since the string invitation clip has a restoring force to open in a natural state, it can be operated with one hand by sandwiching the knobs 1g and 2g with a finger of one hand at an appropriate angle. With the other hand, the stem 5 and the string 4 are supported so that the stem 5 is positioned between the stem support parts 1a and 2a, and the string 4 is between the inner string holding part 1b and the outer string holding part 2b. When the knobs 1g and 2g are sandwiched so as to be located somewhere, the stem 5 is sandwiched between the stem support portions 1a and 2a as shown in FIG. 3 (b), and the string 4 is outside the inner string sandwiching part 1b. It is pinched between the string pinching portions 2b. When the knobs 1g and 2g are further sandwiched, the lock portion 1c enters the opening 2c, and finally the engagement protrusion 1d engages with the engagement portion 2d, and the engagement state is maintained even when the finger is released. The When removing the string citation clip, the first holding piece 1 and the second holding pin 1 are held by the restoring force of the hinge portion 3 by pushing the tip of the lock portion 1c so that the engaging protrusion 1d is separated from the engaging portion 2d. The piece 2 opens and the stem 5 and the string 4 can be removed.
[0014]
When the string 4 is pulled strongly, the string 4 moves to some extent in the lateral direction between the inner string holding part 1b and the outer string holding part 2b. However, as shown in FIG. 3 (d), the string 4 is moved to the hinge part 3 by the claws 1e and 2e. Since it is prevented from reaching, it is possible to protect the thin hinge portion 3 from being pulled by the string 4 and being cut.
[0015]
FIG. 4 is a sectional view taken along line BB in FIG. As shown in the figure, the inner string pinching portion 1b and the outer string pinching portion 2b are each composed of two upper and lower plate-shaped components, each having a gap portion 1f, 2f. Can be bent inward, and the latter can be bent outward so that the string can be clamped regardless of whether the string is thin or thick.
[0016]
【The invention's effect】
As described above, the present invention has the following effects.
(1) Significant cost reduction can be achieved.
5 and FIG. 6 is a product that assembles a plurality of parts into one product and is expensive. However, since the clip of the present invention is integrally molded, the parts and the assembly are completely free of cost. It is unnecessary.
[0017]
(2) Even if the diameter (thickness) of the string varies, it can be surely attracted.
The conventional clip shown in FIG. 5 and FIG. 6 is sold by specifying a string. When a string with a large diameter is used at the time of attraction, there may be a gap at the end of the stalk pinching part, which may not close completely, or the string itself may not be clamped.
Since the clip of the present invention is configured to give elasticity to the string pinching portion even if the diameter of the invitation string varies, the string is surely bitten. Further, since the lock portion is located at the tip of the stem pinching portion and locks, even if the diameter of the invitation string increases, the stem pinching portion remains open as in the conventional product and no gap is formed.
[0018]
(3) It can also deal with attracting methods other than general string attraction.
Since the length of the cord pinching portion is long, the product of the present invention can be attracted by sandwiching the horizontal cord and the stem at a place where the horizontal cord and the stem cross, in addition to a general string attraction method. The conventional clip cannot handle a wide string or the like.
[0019]
(4) Does not damage the stem.
In the conventional product, the stem grew thick during the attraction, and when the clip was removed, the opening portion of the stem pinching portion was not fully opened. In some cases, when removing the clip from the stem, the stem or the branch was folded and removed from the narrow portion 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 are fully opened, so that the stem is not damaged when the clip is removed from the diameter.
[0020]
(5) In the integrated clip shown in FIGS. 7 and 8, since the claw is trying to block the hinge part and the gap is narrow, it is necessary to pay close attention to putting the string inside the claw. Although there is a lot of burden on the person, since the string pinching portion of the present invention is sufficiently long, the operation of pinching the string can be easily performed, and the work can be easily performed in a short time.
