Description

  The present invention relates to a fastener for a post used as a support material for a plant in agriculture and horticulture, and more particularly, to a fastener for an agricultural and horticultural support for connecting and fixing an intersection of two posts at a predetermined angle.

  In recent years, agricultural and horticultural props made of metal poles covered with synthetic resin and made light and durable have become widespread. Used for shelves. Since such assemblages often cultivate different plants depending on the time, the frequency of assembly and disassembly is relatively high, and there are many intersections of struts. The effort was a heavy burden for growers.

  In response to this problem, Japanese Utility Model No. 3047160 proposes a fastener that combines two synthetic resin arms that are inserted and held in a cross in a cross shape to connect the portions where the columns cross at a right angle. . This fastener is assembled and cultivated on a cultivation shelf etc. by connecting and fixing the strut crossing simply by fitting it to the arm and tying and unraveling the string at the crossing strut in its assembly and disassembly It is characterized by the fact that it can reduce the labor of growers greatly.

  However, since this fastener is an integrally molded product of synthetic resin, it has a drawback that it has a relatively short service life because it deteriorates in a relatively short period of time and loses its elasticity when used outdoors. Therefore, as shown in FIG. 5, the central portion of the stainless steel wire, which is elastic and resistant to corrosion, is bent into a U-shape to form a column support portion 14, and the straight portions of the steel wires that are extended and arranged in parallel are shown in the figure. The support column 15 is bent in a direction perpendicular to the bending direction of the support column holding unit 14 to form a support column holding unit 15 in which arcs 150a and 150b are arranged in parallel, and both end sides thereof are further rounded to form pressing units 151 and 152. 1D of the support pillar for use came to spread.

  The fastener 1D can be easily fixed in a state where the struts 41, 41 intersect with each other at a right angle so as to be pressed against each other by the elastic restoring force of the steel wire, and the material is stainless steel. Because it is resistant to corrosion, it can be used for a long time.

  However, in common with the steel wire fastener 1D and the above-mentioned synthetic resin fastener, the thickness of the struts to be applied is limited by the configuration, so the sizes of the struts having different thicknesses are matched. The difficulty is that it is necessary to create fasteners. In addition, these fasteners are assumed to connect struts having the same thickness, and a dedicated one must be created in order to connect struts having different thicknesses.

Further, these fasteners are prepared assuming that the support columns are fixed at a right-angled portion, and when the support columns cross each other at an acute angle of more than 90 degrees, as shown in FIG. It becomes necessary to fix the two vertical (oblique) support columns 41 and 41 to the fastener 41 with the fasteners 1D and 1D, respectively, which increases the number of fasteners and requires labor.

  The present invention is intended to solve the above-mentioned problems. Regarding the connection of agricultural and horticultural supports, the present invention can be used in various situations with fewer types of fasteners while ensuring the ease of connection and opening work. The challenge is to be able to respond.

  Therefore, in the present invention, the steel wire is formed in a substantially oval shape in plan view and is bent in a substantially chevron shape in side view around the center portion where the steel wires are arranged in parallel, and the arcs at both ends form the first support column. Each is inserted and abutted and held on the same side of the outer periphery of the first strut on its inner peripheral surface, and bent by inserting a second strut that intersects the first strut in the inner space by the bent portion of the central portion This is an agricultural and horticultural support brace that connects and fixes two struts at the intersection, and is further bent by elastic deformation around the bent part. In this state, the two struts are connected to each other, and the struts are urged in the direction of pressing at the crossing portions by the elastic repulsive force of the steel wire to fix the connected state.

  In this way, a steel pole is formed into an oval shape and bent into a mountain shape when viewed from the side, and this is a crossing by two columns in a state where it is further bent by elastic deformation around the bent portion. Even if the inner diameter of the arc on both ends does not match the outer diameter of the first strut to be inserted and is larger than this, the steel wire centered on the bent portion With the elastic repulsive force, the two struts can be pressed against each other and the connected state can be firmly fixed.

  In addition, both ends of this steel wire are substantially overlapped while being curved in a U-shape in a symmetrical direction to form one arc, and both ends of this curved steel wire are opened in a direction separating them from each other, so that the struts are If the opening part to be introduced is formed, the connecting / fixing operation becomes easier.

  Further, if both ends of the steel wire forming the open part are formed in a state twisted at a predetermined angle so as to lift the end side when the inner space by the bent part is directed downward, the struts are connected.・ When fixed, the end side elastic repulsive force makes the fixed state more firm, and furthermore, the steel wire is bent at the ends of both ends of the steel wire in a direction opposite to the bending direction to make it circular. If the part is provided, the attachment / detachment work is further facilitated by picking it by hand.

  In addition, if the bent part of the central part is formed in an arc having a larger diameter than the arcs on both ends, the insertion and fixing work becomes easier. If the two struts are formed to be shifted by a predetermined distance near different ends on the line and connected and fixed in a state where they intersect with each other at a predetermined angle, the connecting / fixing of the inclined strut intersections is one. Even with fasteners.

  And if the fastener of the above-mentioned agricultural and horticultural support is made of stainless steel wire, it is easy to realize an appropriate elastic repulsive force and is resistant to corrosion, and has a long service life. it can.

  According to the present invention in which the two struts are connected and fixed in a state where they are pressed against each other with an elastic repulsive force centered on the bent part of the central part as a side view as a general mountain shape, while ensuring the ease of connection and release work It can handle various situations with fewer types of fasteners.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 (A) shows a plan view of a fastener 1A for agricultural / horticultural support that is the first embodiment of the present invention. The fastener 1A is formed of a steel wire having a predetermined thickness made of stainless steel or the like that is highly elastic and resistant to corrosion, bent in a substantially oval shape in plan view like an office clip, as shown in FIG. As shown in the side view of B), it is bent in a substantially chevron shape around the central portion.

  As for fastener 1A, the circular arc of the both ends forms the support | pillar holding | maintenance parts 11 and 12, respectively, and one support | pillar holding | maintenance part 12 curves the steel wire mutually in the symmetrical direction, and the steel wire end part made into the U shape 120a and 120b are configured to overlap with each other while slightly shifted in the length direction of the fastener 1A.

  And the steel wire end parts 120a and 120b which constitute this support pillar holding part 12 are formed in a state twisted at a predetermined angle so as to lift up the straight line portions which are the terminal sides of the steel wires upward, respectively, Furthermore, it is curved in the direction opposite to the bending direction to form circular knobs 121 and 122, respectively, and an open part for introducing the column to the inside by picking them by hand and pulling them up and down in the figure. Is supposed to form.

  With such a configuration, when the fastener 1A is mounted from the side of the support column, the opening portion can be easily opened, and as shown in FIG. Since the end sides of the portions 120a and 120b are pressed downward, the elastic repulsive force makes the struts connected and fixed more rigid.

  Further, as shown in FIGS. 1 (A) and 1 (B), the bent portion at the center portion of the fastener 1A has arcs 130a, It is formed to be curved so as to be 130b, and arc support portions 13A are constituted by arcs 130a and 130b.

  When using such a fastener 1A to connect and fix the intersections of the struts 40a, 40b, the U-shaped steel wire ends 120a, 120b of the strut holding part 12 are gripped by the knobs 121, 122 by hand. As shown in FIG. 1 (C), the crossing portion of the support columns 40a and 40b is introduced into the inside, and the inner peripheral surface of the support column holding portions 11 and 12 on the inner peripheral surface of the support column 40b. Both ends are further bent downward by elastic deformation so as to come into contact with two portions of the portion, and another support column 40a is perpendicular to the support column 40b in the inner space of the support column holding portion 13A forming the bent portion. Insert and hold so that they intersect.

  In this way, the crossing portion of the support columns 40a and 40b can be connected and fixed by the fastener 1A in an extremely simple procedure. By attaching the fastener 1A bent in a substantially chevron shape further, With the repulsive force, both struts 40a and 40b can be strongly urged in the direction of pressing each other at the intersection. Further, by pressing the columns 40a and 40b strongly against each other, the columns held in the column holding parts 11, 12, and 13A can be made by pressing force regardless of the diameter as long as the column is smaller than the diameter of the arc. Since it is firmly fixed by the frictional force of the abutting portion and there is no worry that the fastener 1A is displaced or dropped out, it is possible to cope with struts of various thicknesses with one fastener 1A. Economically superior

  Furthermore, the fastener 1A is a combination of struts 40a and 40b having different thicknesses as long as it can be accommodated in the strut holding portions 11, 12, and 13A as shown in FIGS. 2 (A) and 2 (B). However, the intersection can be easily connected and fixed. And by making this fastener 1A with a stainless steel wire that is resistant to rust, it is possible to use it again and again without worrying that it will hardly deteriorate even when used outdoors, and it will be more economical.

  FIG. 3 (A) shows a side view of the fastener 1B for agricultural and horticultural support according to the second embodiment of the present invention. The fastener 1B is formed in parallel in a state in which the central column support portions 13A in the fastener 1A of the first embodiment are aligned with arcs 130a and 130b formed by bending a steel wire as viewed from the side. On the other hand, the column holding part 13B is characterized in that it is constituted by arcs 131a and 131b formed to be shifted from each other by a predetermined width in the length direction of the fastener 1B as shown in the figure.

  By adopting such a configuration, the fastener 1B can be connected and fixed in a state where the columns 40c and 40d are inclined and crossed as shown in the plan view of FIG. Therefore, in the conventional fastener 1D provided that the strut crossing portion shown in FIG. 6 is a right angle, another strut is required in the lateral direction to connect the strut in an inclined state, and the clasp. Whereas two 1Ds are used, only one fastener 1B is sufficient, which is economical and requires less work. In the case where the diameter of the arcs 130a and 130b of the bent portion 1B is larger than the outer diameter of the support column 40d inserted through the fastener 1B as shown in FIG. 3B, the narrow angle at the support column intersection is 30 to 50 degrees. It can be handled within a range of degrees.

  And when assembling the cultivation shelf of a plant using two types of fasteners 1A and 1B mentioned above, it can assemble by the combination as shown, for example in FIG. In this case, the assembly can be performed in a relatively short time, and the labor of the operator is relatively small. When disassembling this, the disassembly can be easily performed in a relatively short time. Furthermore, when the fasteners 1A and 1B are made of a stainless steel wire that is resistant to rust and is rich in elasticity, there is almost no corrosion and deterioration, and it can be reused many times over many years.

  As described above, according to the present invention, the connection of the agricultural and horticultural support can be facilitated, and the connection / opening work can be facilitated. It became possible to respond to the situation.
