Description

  The present invention relates to a binding tool that easily binds and fixes a plurality of objects to be locked with a string, and more specifically, restricts the pulling direction of a binding string-like member to only one direction and in a direction opposite to the pulling direction. The present invention relates to a string-type binding tool that is difficult to loosen and can maintain the towing state, and that is particularly suitable for use in a crop cultivation process, such as binding of a plurality of stems.

  When growing a crop, if the crop is a vine plant or the crop may fall down due to wind and rain, etc., place a stick in the vicinity of the crop and tie the crop and the rod with a string to position the crop In general, it is necessary to adjust or prevent the body from falling over. However, when tying a crop and a holding rod with a string, there are some aspects that are difficult to tie, such as different sizes of crops. For this reason, the method of binding is likely to be insufficient, and the string may gradually loosen and the crop may fall down. On the other hand, if the method of tying the string is too tight, the stalks of the crops may be pressed unnecessarily, resulting in damage to the crops. Furthermore, the work of tying up with a string seems easy at first glance, but working on each crop has a heavy labor burden.

In addition, as a method of fixing a crop and a holding rod instead of a string, there are a fixing tool imitating clothespins and a hook-shaped fixing tool. However, such a fixture has a drawback that it is difficult to fix the crop and the holding rod in a flexible and reliable manner. Therefore, there is a need for a technique relating to a tying tool that can be flexibly fixed using a string and can be reliably and quickly operated, can reduce costs, and can be provided to consumers at a lower price than conventional products. I can say that.

Conventionally, various technical proposals have been made to solve the above problems. For example, as an invention for fixing a crop with a string and a fixture, an invention that facilitates fixing when hanging a crop by providing two string holes in a plate and passing the string through the string hole is a known technique. (See Patent Document 1). However, this technique is a technique for suspending crops, and is different from the present invention in structure and effect such as a structure and effect for preventing loosening.

In addition, as in the above-described technique, as an invention for fixing a crop with a string and a fixture, an invention is also disclosed in which two holes through which a string-like body passes are provided in an instrument to fix a crop stem (see Patent Document 2). ). However, in such a technique, in the method for fixing the string, the configuration and the like are different from those of the present invention in that a knot of the string or a dedicated fixing tool is used.

JP-A-10-178923 6-45431

  In view of the above problems, the present invention can easily bind and fix a plurality of objects to be locked simply by pulling the string-like member, and restricts the pulling direction of the string-like member for binding to only one direction. The present invention aims to provide a technique for a string-type binding tool that is difficult to loosen in a direction opposite to the direction and can maintain the towing state, and is particularly suitable for binding a plurality of stems or the like in growing a crop.

  In order to solve the problems of the conventional string-type tying tool as described above, the present applicant is based on the idea that it can be solved by using the elastic force of the plate-like member and further multiplexing the elastic force. The technical proposal of the “string-type binding tool” according to the present invention has been made.

  The present invention relates to a binding tool comprising one string-like member, two or more plate-like holding members, and one or more spacer members, wherein the string-like member is a string-like string formed by bundling fibers. In the plate-like holding member, a string-like member insertion slit portion that is cut in order to allow the string-like member to be inserted from an outer peripheral edge portion, and a radial shape centering on the tip of the string-like member insertion slit. A string-like member holding slit part to be cut is provided, and the string-like member holding slit part restricts the pulling direction of the string-like member inserted from the string-like member insertion slit part to only one direction, In order to maintain the traction state, the spacer member is formed to be bent or curved toward the tip and protrude in the traction direction, and the spacer member is provided to ensure a bending or bending depth region of the string-like member holding slit. The space area required for It has a structure of the cord-type closure is a spacer for providing between Jo holding member.

Moreover, this invention can also be set as the said string type binding tool of the structure which uses the biodegradable resin for the raw material in any of the said plate-shaped holding member and the said spacer member.

Moreover, this invention can also be the said string type binding tool of the structure in which the shape in the said spacer member is formed in the substantially H shape so that the space area | region between the said string-shaped member holding | maintenance slit part may be interrupted | blocked.

Further, in the present invention, the shape of the spacer member is separated so as to be along the two sides of the plate-like holding member so as not to block the space region between the string-like member holding slit portions. It can also be set as a string-type binding tool.

Further, the present invention can also be the string-type binding device in which the material of the plate-shaped holding member and the spacer member is the same, and the joining method is based on welding.

  According to the string type binding tool of the present invention, since the notch of the string member holding slit portion is bent or curved toward the tip, the sharp tip bites into the twisted string, and the string member is pulled. The direction can be limited to only one direction, and further, by multiplexing this, a higher locking effect is obtained, so that an excellent effect that this traction state can be maintained for a long time is exhibited.

In addition, the conventional clip-type binding tool has an advantage that it is convenient and has good workability, but there are many components and there is a problem of the cost. Furthermore, there is also a problem that when a soft plant stem or the like is bound, it is easily damaged. On the other hand, in the present invention, since the traction force of the string-like member can be freely adjusted, the excellent effect of being able to adjust to the binding force corresponding to the strength and weight of the object to be bound is low-cost. Demonstrate.

Further, with a conventional tying tool for tying a string, the tying work is complicated and time-consuming, and the working time becomes long and the working efficiency is poor. Also, the knot may loosen or break. Furthermore, if the string stretches over time, the knot must be unwound and tied again. On the other hand, in this invention, since it is not necessary to tie a string-like member, workability | operativity is good and the problem of loosening and the unraveling by presence of a knot does not arise. Moreover, even when the string-like member has been stretched, an appropriate binding force can be maintained by appropriately re-drawing.

Further, according to the string-type binding device according to the present invention, it is necessary to continuously and repeatedly perform binding in which the outer diameters of the objects to be bound are greatly different, such as binding of a plurality of stems or the like. Even in such a case, it is not necessary to adjust the length of the string-like member or the knot position, the operation is extremely easy, and the working time can be shortened.

Moreover, according to the string type binding tool according to claim 2, since the biodegradable resin is used as the material for both the plate-like holding member and the spacer member, the string-like member is made of hemp string or the like. If natural materials are used, even if they are dumped in landfills, microorganisms will eat and decompose them, so it can be returned to the soil as it is, and it will not take time to remove and dispose of it and will not accumulate as garbage. Exhibits excellent effects.

Moreover, according to the string type binding tool according to claim 3, since the shape of the spacer member is formed in a substantially H shape so as to block the space region between the string member holding slit portions, Since the entire binding tool can be made rigid, if the object to be bound is hard, the string-like member can be pulled strongly, and it exhibits an excellent effect that it is suitable for use in which a strong binding force is required. To do.

Moreover, according to the string type binding tool according to claim 4, the shape of the spacer member is along the two sides of the plate-shaped holding member so as not to block the space region between the string-shaped member holding slit portions. Because they are separated from each other, the entire string-type binding tool is flexible, and even if the object to be bound is soft, such as a plant stem, damage to the object to be bound such as scratches or deformation It exhibits an excellent effect that it is suitable for use modes that do not want to be given. Pear missing

Further, according to the string-type binding device according to claim 5, since the raw material of the plate-like holding member and the spacer member is the same, bonding by welding is possible, no adhesive is required, and the resin material Since it can be reused, it has an excellent effect of contributing to effective use of resources.

  The string type binding tool 10 according to the present invention has a string-like member 70 inserted through a notch from the outer peripheral edge of the plate-like holding member 20 and is formed by a string-like member holding slit part 60 by a radial notch formed at the tip thereof. A space necessary for securing the bent or curved depth region, in which the string-like member holding slit 60 is bent or curved toward the radial center tip and protrudes in the pulling direction. In order to secure the region 40, the greatest feature is that a configuration using the spacer member 30 is employed. Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In addition, a dimension and a shape are not specifically limited to the Example described below, It can change arbitrarily in the range of the creation included as a technical idea which concerns on this invention.

  The string type binding tool 10 according to the present invention is composed of a single string-like member 70, two or more plate-like holding members 20, and one or more spacer members 30, and FIG. FIG. 1 (a) shows an overall configuration as viewed from the object to be bound, and FIG. 1 (b) shows a component configuration of the string type binding device 10 according to FIG. It shows. FIG. 2 is an explanatory view of the binding state of the string type binding device 10 according to the present invention, and FIG. 2 (a) is a binding object side plate-shaped holding member that becomes the plate-shaped holding member 20 on the binding side of the binding object 80. FIG. 2B shows a state in which the member 22 is arranged on the front side in the drawing, and FIG. 2B shows the string-like member pulling side plate-like holding member 21 serving as the plate-like holding member 20 on the side pulling the string-like member 70 on the front side. It shows the state of being placed in.

The string-like member 70 is a cocoon string body in which fibers are bundled as shown in the enlarged views of FIGS. 3B and 3C, and may be a knitted string structurally. As for the shape, a substantially circular shape is desirable in a sectional view, but even a flat shape can be used. If a general chemical fiber such as polyester, polyethylene, polypropylene, or nylon is used as the material, it is strong and can be manufactured at low cost. In addition, if the object to be bound is a heavy object that floats, an extremely strong aramid fiber or Kevlar (registered trademark) may be considered. On the other hand, when natural fibers such as cotton, hemp, manila, and jute are used, although they are inferior to chemical fibers in terms of cost and strength, they can be buried directly in the soil when used for crop binding, etc. In the string type binding device 10 according to claim 2, since the two or more plate-like holding members 20 and the spacer member 30 are made of biodegradable resin, they can be discarded such as being buried in the soil while being bound together. It is. Note that the reason why the braided cord or the braided cord is used is that, as shown in FIG.

FIG. 3 is an explanatory view of the plate-like holding member 20 according to the present invention. FIG. 3A shows the overall shape, the arrangement relationship of the string-like member holding slit portion 60, and the string-like member insertion slit portion 50, and shows the string-like member holding slit portion 60 in an enlarged manner. 3 (b) and 3 (c) are formed so that the distal end cut radially from the distal end of the string-like member insertion slit 50 is bent or curved and protrudes in the pulling direction. In addition to exemplifying the projected shape, each enlarged view is shown. Specifically, FIG. 3B shows a shape when a side near the radial outer edge is folded and protruded in a dogleg shape, and FIG. 3C shows a gently curved protruding shape, Each enlarged view is shown in a dashed line circle. When the tip of each string-like member holding slit portion 60 is compared between FIG. 3B and FIG. 3C, the reaction force with respect to the loosening direction of the string-like member 70 is better when the shape shown in FIG. Although the direction is the same as that shown in FIG. 3B, the binding force and the effect of preventing loosening are great. However, when the string-like member holding slit portion 60 is formed by the curve of FIG. 3C, the hole through which the string-like member 70 is inserted has a larger diameter than the bend of FIG. The shaped member 70 uses a thick string correspondingly.

The plate-like holding member 20 is composed of at least two pieces of a string-like member pulling-side plate-like holding member 21 and a bound object-side plate-like holding member 22 through a spacer portion 30. In the case where the plate-shaped holding member 20 is composed of three or more plates, the intermediate plate-shaped holding member 23 and the spacer member 30 are further added.

The plate-like holding member 20 is provided with a string-like member insertion slit portion 50, and the string-like member insertion slit portion 50 removes the string-like member 70 from the outer peripheral edge portion of the plate-like holding member 20. It is a cut for insertion, and the cut at the outer peripheral edge of the plate is large, narrows toward the center of the plate, and is narrow from the middle of the cut to the tip. By adopting such a shape, the string-like member 70 can be easily inserted from the side surface, and the string-like member 70 inserted to the tip of the notch is prevented from being easily removed.

Further, the plate-like holding member 20 is provided with a string-like member holding slit portion 60, and the string-like member holding slit portion 60 is formed by cutting radially from the tip of the string-like member insertion slit portion 50. Is a set of multiple intercepts. Although the number of segments of the string-like member holding slit part 60 shown in FIGS. 1 to 3 is eight pieces, FIG. 4 shows another embodiment of the string-like member holding slit part 60 shown in FIG. 4 pieces or 3 pieces may be sufficient as shown in FIG.4 (b) and FIG.4 (c). However, since it is desirable that an equal force acts on each piece on the string-like member 70, it is desirable that the string-like member is radially isotropically divided from the tip of the string-like member insertion slit portion 50.

The section of the string-like member holding slit portion 60 protrudes in the pulling direction of the string-like member 70 as shown in FIGS. 3 (b), 3 (c), 6, 7, and 8. The slice has a shape in which the central portion of the radiation protrudes most. 3 (b) and 3 (c) are formed so that the distal end cut radially from the distal end of the string-like member insertion slit 50 is bent or curved and protrudes in the pulling direction. The protrusion shape is illustrated and each enlarged view is shown. Specifically, FIG. 3B shows a shape in which a side near the radial outer edge is folded and protruded in a dogleg shape, and FIG. 3C shows a gently curved protruding shape. Yes.

In addition, about the whole shape of the plate-shaped holding member 20, it does not limit to the elliptical shape as shown in each figure, A rectangular shape like a rectangle may be sufficient. However, in the case of using in dense crops, the shape having no corners is desirable from the viewpoint of damage due to contact.

Moreover, as for the material of the plate-like holding member 20, a general synthetic resin or the like can be considered. For example, polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyvinyl acetate. Common materials such as (PVAc), Teflon (registered trademark) (polytetrafluoroethylene, PTFE) ABS resin (acrylonitrile butadiene styrene resin), AS resin, acrylic resin (PMMA) may be used. If engineering plastics such as polycarbonate (PP) are used, they have a tensile strength of 49 MPa or more and a flexural modulus of 2.5 GPa or more. Therefore, even if the plate-like holding member 20 is thin, it is firmly bound by a large traction force. It is also possible to cope with a usage mode in which the above is required.

However, in the string type tying tool 10 according to claim 2, it is specified that a biodegradable resin is used as the material for both the plate-like holding member 20 and the spacer member 30, and thereby the soil The plate-like holding member 20 according to claim 5 is welded to these joints by using the same material as that of the spacer member 30. Identifies what can be adopted

FIG. 5 is an explanatory view of a spacer member 30 according to the present invention. FIG. 5 (a1) shows the configuration of the spacer member 30 according to claim 3, and FIG. Each form of the spacer member 30 is shown. Corresponding to these, changes in shape in use are shown in FIGS. 5 (a2) and (b2), respectively.

In the spacer member 30 according to the third aspect, the shape of the spacer member 30 is formed in a substantially H shape so as to block the space region 40 between the string-like member holding slit portions 60. This is because the shape of the spacer member 30 blocks the space region 40 between the string-like member holding slit portions 60, thereby increasing the rigidity of the string-type binding device 10 as a whole. Even if it is pulled with a strong traction force, as shown in FIG. 5 (a2), the entire deflection amount is suppressed. Therefore, when the object to be bound for binding is a hard object or a heavy object, for example, the string-like member 70 is pulled by nylon-based chemical fiber or polyamide-based Kevlar (registered trademark). A strong material is used, and an engineering plastic such as polycarbonate (PP) is used for the plate-like holding member 20, which is suitable for a usage mode in which a strong binding is obtained by applying a large traction force.

On the other hand, in the spacer member 30 according to claim 4 having the shape shown in FIG. 5 (b 1), the two sides of the plate-like holding member 20 so as not to block the space region 40 between the string-like member holding slit portions 60. Are separated from each other. This is because the shape of the spacer member 30 does not block the space region 40 between the string-like member holding slit portions 60, thereby suppressing the rigidity of the string-type binding device 10 as a whole and strengthening the string-like member 70. Even if it is pulled by traction force, as shown in FIG. 5 (b2), it is suitable for bundling such as crops that are easily damaged or stress deformed by being bent by the overall elasticity. . In addition, about the dimension of each part of the string-like member 70, when the concentrated load acts between both ends support from the allowable amount of deflection, the pulling force that pulls the string-like member 70, the sectional second moment or the section modulus due to the sectional shape, etc. By calculation, the finally required cross-sectional area is calculated, and the thickness and width are determined as appropriate.

The space region 40 provided in the spacer member 30 is a spatial region necessary for securing a bending or bending depth region of the string-like member holding slit, and the string-like member holding slit portion 60. It is necessary to secure a thickness that is equal to or greater than the protruding amount of the section.

  FIG. 6 is an explanatory diagram of a multilayer structure of the string type binding device 10 according to the present invention. FIG. 6A shows the configuration after assembly, and FIG. 6B shows the configuration before assembly. FIG. 6 shows a configuration example of three plates as another embodiment, but it is possible to increase the number of layers as necessary. Between the string-like member pulling side plate-like holding member 21 and the object-to-be-bound side plate-like holding member 22, an intermediate plate-like holding member 23 is provided in the middle via spacer members 30 on both sides.

FIG. 7 is an explanatory view of the holding state of the string-like member 70 according to the present invention. The effect of using two or more plate-like holding members 20 will be described with reference to FIG. (A), (b), (c) is a schematic diagram which shows the relationship between a plate, the string-like member holding | maintenance slit part 60, and the string-like member 70. FIG. The string-like member holding slit portion 60 formed in each plate-like holding member 20 protrudes leftward in the drawing, and holds the string-like member 70 by elastic force. When the string-like member 70 is pulled out in the left direction, the segment of the string-like member holding slit portion 60 protrudes in the left direction, and the string-like member 70 is pulled out without any problem. On the contrary, if the string-like member 70 is pulled rightward, the protrusion of the section of the string-like member holding slit portion 60 is lowered, and the string-like member 70 is held by a stronger force, resulting in the string-like member. The return to the right of 70 is restricted. 7A illustrates the case where the tip of the section of the string-like member holding slit portion 60 is curved and protrudes, and in FIG. 7B and FIG. 7C, the string-like member holding slit portion. The cases where the tips of 60 sections protrude by bending are illustrated.

  The regulating force is generated at the tip of the section of the string-like member holding slit portion 60 and the constricted portion of the string-like member 70. Therefore, in (a), the regulating force is generated at the sections of the string-like member holding slit portion 60 of the string-like member pulling-side plate-like holding member 21 and the object-to-be-bound-side plate-like holding member 22, so Occur. (B) is a case where three plates are used. Since the regulating force is generated at the sections of the string-like member pulling side plate-like holding member 21, the intermediate partial plate 10, and the bound object side plate-like holding member 22, the regulating force is generated at each of the three plates. Thus, the more the plate, the greater the regulation force, and the effect of the string type binding tool 10 can be increased. However, (c) is a case of two plates without the space region 40, but the regulating force generated at the tip of the section of the string-like member holding slit portion 60 and the neck portion of the string is the string-like member. It occurs only in the string-like member holding slit part 60 of the pulling-side plate-like holding member 21 and does not occur in the string-like member holding slit part 60 of the bound object-side plate-like holding member 22. Therefore, although the number of the plate-like holding members 20 is two, the increase in regulation force cannot be expected. Thus, in order to increase the force that regulates the return of the string-like member 70, the space region 40 is necessary.
