Description

  The present invention relates to a plant stem invitation clip for fruit vegetables such as tomato, eggplant, pepper, cucumber and melon.

  Fruit vegetables such as tomatoes, eggplants, peppers, cucumbers and melons cannot stand by their own weight when the stems grow. Therefore, in vinyl house cultivation (facility horticulture), as shown in FIG. 10, an invitation string 101 for lifting a stem was attached to an induction line 100 stretched horizontally on the ceiling of the vinyl house, and was suspended. As shown in FIG. 11, the attracting string 101 is sandwiched by the attracting string sandwiching portion 52 near the fulcrum 51 of the attracting clip 50 as shown in FIG. And an upright attraction method for lifting the stem S.

  As another method, as shown in FIG. 12, the pillars 102 are set up at regular intervals on the ridges in the vinyl house, and several stages are attached in the horizontal direction while the attraction string 103 is wound around the pillars 102. As shown in FIG. 13, the attracting cord 103 laid horizontally by the attracting cord sandwiching portion 52 near the fulcrum portion 51 of the inviting clip 50 is sandwiched between the cord 103 and at the same time, the tomato is held in the stem holding portion 53 of the inviting clip 50. A horizontal attraction method in which a stem S such as the above is sandwiched and the stem S is slanted is also widely used. In addition, as shown in FIG. 16, the invitation clip 50 is an integrally formed product in which the left and right knobs 54 and 55 and the middle portions of the sandwiching pieces 56 and 57 are flexibly connected by the fulcrum 51, and the left and right sandwiching clips A C-shaped metal wire spring 58 is attached from the outside between the pieces 56 and 57, and an elastic force is applied in a direction in which the holding pieces 56 and 57 are closed.

  As another invitation clip using a metal wire spring, those described in Patent Documents 1 to 3 have been proposed.

  In addition, as in the case of the cited clip 70 shown in FIG. 19 and FIG. 21, the sandwiching clip-type sandwiching pieces 71 and 72 are combined by the hinge projection 74 and the hinge recess 75 so as to be freely opened and closed, and the sandwiching piece by the C-shaped metal wire spring 76. In some cases, 71 and 72 are sandwiched and a string sandwiching portion 73 is provided in front of the hinge portions of the sandwiching pieces 71 and 72.

The following describes the case of tomato horticulture.
In greenhouse horticultural cultivation (vinyl house cultivation), in particular, long-term cultivation of tomatoes is carried out for almost a year.
Harvest from the part close to the root of the stem and shift the harvested stem part downward. At the same time, the growing portion extends upward, so that the stem is not broken, and as shown in FIG. 14 and FIG.
The inside of the vinyl house is faster than the one used outside the vinyl house due to spraying of chemicals or ultraviolet rays, etc., and the use of the clip is repeated every year. More damage.

In the case of tomato, it is attracted by using 2 to 3 citation clips on one stalk, and 2000-2100 stalks are planted in one (about 990 m ² ) vinyl house. In order to reduce the amount of work and the work, it is necessary to provide a citation clip with good workability, which does not deteriorate even when used for many years at a low price.

As shown in FIGS. 17 and 18, the clip 60 described in Patent Document 2 includes a fulcrum shaft of another part serving as a fulcrum in the holes 63 and 64 of the sandwiching pieces obtained by combining the two sandwiching pieces 61 and 62. 65, and then a metal spring 66 is attached to make a product, which is a clip having a mechanism for sandwiching a stem and a string, and a separate part to be a fulcrum shaft 65 is required, so the cost is high and the producer purchase price is also high Get higher.
In addition, when repeatedly engaged and attracted for many years, the fulcrum shaft 65 is removed or the vicinity of the holes 63 and 64 through which the fulcrum shaft 65 is passed is thinned. It may break or break from the central part of the clamping pieces 61, 62 near 64.

  Since the clip described in Patent Document 3 does not use a fulcrum shaft, there is no hole through which the fulcrum shaft passes, and even if it is used repeatedly for many years, it does not break from the center part of the sandwiching piece due to deterioration. The hinge part of the thin part is deteriorated when used repeatedly for many years. It may break from the hinge.

A conventional clip 70 shown in FIG. 19 combines two holding pieces 71 and 72 without incorporating a fulcrum shaft, and presses the stem holding portion 77 only by the pressing force of the spring 76. As shown in FIG. When the attracting cord 101 is sandwiched between the attracting cord sandwiching portion 73 near the hinge portion serving as a fulcrum, the attracting cord 101 sandwiched by the force of the spring 76 holding the stem holding portion 77 serves as a fulcrum, and the clamping pieces 71 and 72 The combination part of the hinge convex part 74 and the hinge concave part 75 which become a fulcrum is lifted. Therefore, the force which pinches the attracting string 101 becomes weak, and when used in the upright attracting method, the invitation clip 70 is shifted downward by the weight of the stem, and the stem cannot be firmly fixed.
Among them, there is an invitation clip in which an undercut 78 (see FIG. 21) is provided on the inner side of the combination part so that it does not float even if the induction string is sandwiched between the induction string sandwiching parts in the combination part of the two holding pieces. Because it is a slight undercut, the undercut 78 is crushed when the attracting cord is repeatedly pinched and opened and closed, and when the attracting cord 101 is pinched, the combination part of the holding pieces rises, and the force that pinches the attracting cord 101 The reference clip 70 is shifted downward due to the weight of the stem, and the stem cannot be firmly fixed.

Japanese Patent Publication No. 5-15405 Utility Model Registration No. 3018081 Design Registration No. 1397460

The cited clip described in the above-mentioned Patent Document 2 is a combination of two clamping pieces, using a separate fulcrum shaft, and assembling with a metal spring, the labor to assemble increases, and the fulcrum shaft is manufactured separately. The cost of the product increases and the purchase price of the producer also increases.
In addition, since it is necessary to form a hole for passing the fulcrum shaft through the sandwiching piece, if it is used for many years, if the knob is picked to open the stem holding part, a force is applied to the outside of the fulcrum part of the sandwiching piece. For this reason, the holding piece may be broken from the combination part of the holding piece near the fulcrum part.

  In the cited clip described in Patent Document 3, two holding pieces are integrally formed with a hinge part, and the stem holding part is opened and closed with the hinge part as a fulcrum, so that a separate fulcrum shaft is unnecessary. Since the hole for passing the fulcrum shaft is not necessary, the strength of the clamping piece body is increased and the cost is reduced, but the thin hinge part is pulled and the burden is heavy and deteriorated by pinching the attracting string repeatedly for many years. May crack.

  Since the conventional product shown in FIG. 19 is an invitation clip that combines two clamping pieces without using a fulcrum shaft or a thin hinge, an attracting string is placed near the combination of the hinge convex part and hinge concave part serving as a fulcrum. When pinched, the pulling cord becomes a fulcrum by the force of the spring holding the stem holding part, the combination part of the hinge convex part and hinge concave part that becomes the fulcrum opens, and the force to pinch the attracting string becomes weak, When used, the invitation clip holding the attracting string with its own weight slides downward and cannot be firmly fixed.

  Therefore, the present invention is a facility horticulture (vinyl house cultivation), always depending on the growth and harvest of the stem, in the environment such as stem replacement, movement, chemical spraying, UV irradiation, etc. The purpose of the present invention is to provide an invitation clip with good workability, which is low in price and does not deviate from the attraction string due to the weight of the stem.

  In order to solve the above-described problems, the plant stem citation clip of the present invention has a pair of sandwiching pieces each having a knob and a stem holding part, a shaft part in one sandwiching piece, and a sandwiching piece in the other sandwiching piece. Is provided with a hook portion that is open on the side of the knob portion that engages with the shaft portion, and a cord pinching portion that engages with an attracting cord is formed on the stem portion and the stem holding portion side of the hook portion. The pair of holding pieces is provided with a protrusion that prevents the hook portion from being detached toward the stem holding portion when the stem holding portions of the pair of holding pieces are closed to each other. It is characterized by providing a C-shaped spring that presses so that the stem holding part side of the stalk is closed.

  In the present invention, by combining the clamping piece provided with the hook portion and the clamping piece provided with the shaft portion which is engaged with the inner portion of the hook portion and serves as a rotating shaft, a fulcrum shaft as a separate part becomes unnecessary, and the cost is reduced. Since the hole for passing the fulcrum shaft through the clamping piece is not necessary, the strength of the clamping piece body is improved.

  In addition, since the two clamping pieces are not integrally connected with the thin hinge portion as a fulcrum, even if the attracting operation is repeated for many years, the damage due to deterioration is less than that of the conventional cited clip.

  Furthermore, when the stem holding part is opened, even if the force of the metal spring holding the pair of holding pieces is strong, the picking part is picked, the stem holding part is opened widely, the outside of the holding piece main body, Even if a large force is applied near the combination part, the holding piece main body does not have a hole for passing the fulcrum shaft, so even if it is used for many years, it does not break due to deterioration from the vicinity of the combination part of the holding piece serving as a fulcrum.

  By forming a notch that engages with a predetermined overlap margin at the tip of both stem holding portions of the pair of sandwiching pieces, even if the tip holding portion tip is slightly opened due to a thick attracting string, etc. It is not opened, the stem is not damaged at the tip of the stem holding part, and the stem is not detached.

  According to the present invention, in the middle part of the pair of holding pieces each having a knob part and a stem holding part, one holding piece has a shaft part open, and the other holding piece engages with the shaft part. Each of the hook portions is provided, and a string holding portion is formed on the stem holding portion side of the shaft portion and the hook portion to engage with the attracting string, and a pair of holding pieces is provided on one of the pair of holding pieces. Protruding portions that prevent the hook portions from detaching to the stem holding portion side when the stem holding portions of each pair are closed are provided, and a C-shaped spring that presses the stem holding portions of the pair of sandwiching pieces is closed. By the facility horticulture (vinyl house cultivation), depending on the growth and harvesting of the stem, always in the environment of stem replacement, movement, chemical spraying, UV irradiation, etc. Invitation with good workability that does not deviate from the drawstring due to the weight of the stem at a low price Lip is obtained.
