Description

  The present invention relates to a stem when a tomato, cucumber, eggplant, melon, flower, fruit tree, etc., a plant stem, seedling, vine, stem, etc. (hereinafter sometimes abbreviated as “stem etc.”) grows. The present invention relates to a support such as a stalk for fruit trees that supports the weight so that it does not hang down to the ground due to its own weight.

The stems, seedlings, vines, and trunks of plants such as tomatoes, cucumbers, melons, eggplants, flowers, fruit trees, etc. try to grow as they grow. Then there are insects that can be eaten or sick. Therefore, to prevent the stems and seedlings from falling or breaking, wrap an attracting string around the stems, hang the braces and stems with adhesive tape, tie them with strings, fasten them with plastic clips, etc. .
With the method of fastening with adhesive tape or the method of tying with a string, you have to wrap and tie them using both hands, and it takes time to remove them. For this purpose, various plastic clips have been proposed (for example, see Patent Documents 1 to 5).

  The stem, stem, and vine invitation clip disclosed in Patent Document 1 is provided with a synthetic resin support grip ring having an inner diameter corresponding to an iron wire as a support, and arc-shaped locking at both ends of the support grip ring. A body and an operating rod are provided, and the support gripping ring is fitted and engaged with the iron wire by utilizing the spring elasticity with the operating rod sandwiched with one hand, and the vine is attracted and fixed in the attracting space.

  The binding tool for an attracting line of a plant stem disclosed in Patent Document 2 includes a pair of pinching pieces having a semicircular ridge at one end and an operation portion at the other end, and the inside of the middle abdominal portion of the pinching piece that bulges to the center. The intermediate portion of the clip piece is fitted in the support groove, combined in a symmetrical clothespin shape, and attached to the hanging soft attracting string.

  In the plant stem clip disclosed in Patent Document 3, a pair of clamping members coupled to each other at a fulcrum has a stem holding piece bent forward from the fulcrum and a grip piece projecting rearward from the fulcrum. In the clip for plant stem holding, provided with a plurality of teeth that mesh with each other at the base part of the stem holding piece and hold the string, and the holding member is elastically closed by the elastic member on both holding members. The height of the tooth part located inside is higher than the tooth part located outside in the state in which the provided tooth parts mesh with each other.

  The plant stem invitation clip disclosed in Patent Document 4 has a pair of first and second sandwiching pieces formed by connecting a semicircular stem support portion and a knob portion supporting the stem in the middle portion. An end portion of a C-shaped spring which is integrally formed so as to be freely opened and closed by a hinge portion, and gives elastic force in a closing direction to the stem support portion on the waste portion of the semicircular stem support portion of the first and second clamping pieces. A string locking protrusion and a rectangular opening that are engaged with each other when both the holding pieces are closed are provided on the opposing surfaces closer to the stem support part than the hinge parts of the first and second holding pieces. Formed.

  The clip disclosed in Patent Document 5 has spherical sphere ends at both ends, a circle with a radius r1 having a center at the center A at the center, and a center B near the sphere ends at both ends.

  However, the appliances disclosed in Patent Documents 1 to 4 have a clothespin-shaped knob, and when used, the knob is pressed with a force larger than the spring force to open the front clip and open. There is a problem that hands are tired when attracting a large number of fruit trees.

  In addition, in the device disclosed in Patent Document 5, when removing the stem, stem, vine or support, twist the sphere entangled with the tip of the clip to release the entanglement and hold the knob to hold the stem, vine, seedling holding container. It is necessary to open and remove the mouth, and there is a need to change it, which takes time to install and remove.

  Moreover, since the apparatus described in patent documents 2-4 requires the operation | work which assembles both using a plastic main body and a metal spring, parts cost and manufacturing cost are high, and it provides to a producer at low price. I can't.

  The device of Patent Document 1 that is lightweight and integrally molded without using a metal spring is molded using a POM (polyacetal resin) raw material in order to increase the strength and elasticity of the clip. Therefore, after harvesting of tomatoes, cucumbers, eggplants, melons, etc., and after the stems of the flowers withered, they may be incinerated, but when the stems and vines are incinerated, the clips formed with POM are mixed and incomplete When burning, a strong irritating odor and harmful formaldehyde gas (formalin) may be generated, which is bad for the environment.

  The present invention does not require a separate part such as a metal spring, and has a stable state holding function in both the opened state and the closed state, and a fruit tree stem support that can be integrally molded with plastic. The purpose is to provide.

  In order to solve the above-described problems, the support for a fruit tree stalk of the present invention is such that the middle part of the first gripping part and the second gripping part are coupled to be openable and closable by the first hinge part, and the tip of the first gripping part A small column is connected between the arm part connected to the part and the tip of the second gripping part so as to be able to be bent with the second hinge part and the third hinge part as fulcrums, respectively, With the third hinge portion on the straight line connecting the second hinge portions as a boundary, the third hinge portion is on the first gripping portion side and the second gripping portion side with respect to the straight line In some cases, the base end portions of the first gripping portion and the second gripping portion are stably held in an open state and a closed state.

  In the present invention, the first gripping part and the second gripping part are opened and closed using the elasticity of plastic, which is the material of the support such as a fruit tree stalk, without requiring separate parts such as a metal spring. A stable state maintaining function is provided in both states. That is, for example, when manufacturing a support for stems and the like for the fruit tree in a shape in which the first gripping portion and the second gripping portion are open, by injection molding or the like, with respect to a straight line connecting the first hinge portion and the second hinge portion The product is molded in such a state that the third hinge part is on the first gripping part side (first stable state). When the first gripping part and the second gripping part are closed in a state where a stem, a support column, an attracting string, etc. are mounted in the space between the first gripping part and the second gripping part in use, the length of the trabeculae Therefore, the arm portion and the distal end portion of the second gripping portion are elastically deformed, and a force is applied to open the first gripping portion and the second gripping portion. When the first gripping part and the second gripping part are further closed against the force, the third hinge part is located on the straight line connecting the first hinge part and the second hinge part (dead point). The third hinge part is positioned on the second gripping part side with respect to the straight line. If it does so, the force holding a closed state will become stronger than the elasticity which tries to open a 1st holding part and a 2nd holding part, and the state is hold | maintained (2nd stable state). In this way, the support such as a fruit tree stalk can be held in both the open state and the closed state. Using this, the stem and the like can be supported by bundling the stem and the like with the attracting string and the support in the space part sandwiched between the first gripping part and the second gripping part. When the first gripping portion and the second gripping portion are opened again, the first gripping portion and the second gripping portion are supported by using the first hinge portion as a fulcrum if the distal ends of the first gripping portion and the second gripping portion are pressed with a finger or the like. Will open and return to the first stable state.

By forming a hook portion to be fixed to a support column or string at the tip of the first grip unit, a stem or the like is supported between the first grip unit and the second grip unit through the support column or string. be able to.
By forming a clamping part at the base end part of the first gripping part and the second gripping part, it is possible to stop the struts and the string at the clamping part.
By forming an anti-slip part for finger grip when opening and closing the first grip part and the second grip part on the outer side of the base end part and the outer side of the tip part of the first grip part and the second grip part, respectively. The opening / closing operation can be performed smoothly, and it can be estimated that the opening / closing operation can be performed by holding the place.
By using weather-resistant polypropylene as the material, it is possible to slow down the deterioration of the material due to sunlight, and to prevent the generation of harmful substances when supporting uncollected fruit tree stalks and other support materials at the time of harvest. Can do.

  According to the present invention, the middle part of the first gripping part and the second gripping part are coupled so as to be openable and closable by the first hinge part, and the arm part and the second gripping part connected to the tip part of the first gripping part are connected. The small column is connected between the tip and the second hinge part and the third hinge part so as to be bendable, and the third hinge part is on a straight line connecting the first hinge part and the second hinge part. The base end of the first gripping part and the second gripping part is opened when the third hinge part is on the first gripping part side and the second gripping part side with respect to the straight line. By holding the closed state and the closed state stably, it is possible to obtain a support such as a stem for fruit trees that can be integrally molded with plastic without requiring separate parts such as a metal spring.

Producers such as fruit trees usually have to save thousands of tens of thousands of stalks, seedlings, vines, and so on, and only need to skip one of the many attracting steps to perform the attracting work. Leads to saving tens of thousands of operations.
When attracting and holding stems, seedlings, vines, etc. on a support post or an attracting string, the gripping part is fully open from the beginning, so there is no need to open the gripping part, cut the tape, or tie it with a string. Moreover, it is not necessary to tie the grip portion with a string from the beginning. If a stem, a seedling, a vine or the like is passed through the gripping portion as it is and the outside of the gripping portion is pressed to some extent, the gripping portion is automatically closed by a spring force, and the stem, the seedling, the vine and the like can be held.

When removing stems, seedlings, and vines from the gripping part, if you hold the tip side of both gripping parts and hold them to a certain extent, the base end of the gripping part is automatically opened fully open by the force of the spring, and the next When it is in a state where it can be attracted and held, and when it is attracted and held to the next location, it is possible to omit the step of opening the proximal end portion of the grip portion again.
The gripping part opens and closes automatically by applying a certain amount of force with the integrally formed spring, so there is no need to keep pressing down to the end, so it is possible to reduce the attracting and holding work process of stems, seedlings, vines, etc. The burden on the finger can be reduced.

  The support for stems and the like for fruit trees can be opened and closed with a single touch, so that the workability is good, and since it has an integrally formed spring mechanism, it can be securely locked without incorporating a metal spring or spring component. Moreover, since it is integrally formed with PP (polypropylene resin), which is an olefin-based general-purpose resin, it can be produced at low cost and can be provided to producers at low cost. Moreover, since it can be used repeatedly, the burden of attracting material costs can be reduced.

  In addition, since there is a spring function using a hinge part that mechanically locks, there is no need to mold with POM (polyacetal resin), and when harvesting stems, vines, etc. after harvesting, clips are accidentally mixed in. However, no harmful gas is generated.

In addition, by forming a hook part to be fastened to the column or string at the tip of the first holding part, a stem or the like is supported between the first holding part and the second holding part through the column or string to the hook part. can do.
By forming the clamping portion at the base end portions of the first gripping portion and the second gripping portion, the support column and the string can be stopped by the clamping portion.
Opening and closing operations are formed by forming anti-slip portions for finger grip when opening and closing the first gripping portion and the second gripping portion on the outer side of the proximal end and the outer side of the distal end of the first gripping portion and the second gripping portion, respectively. Can be performed smoothly, and it can be inferred that the opening / closing operation can be performed by holding the place.
