Shaping jig for fixing wire for drainage holes in pots.

Abstract

This invention provides a wire bending jig for securing mesh, which, despite its simple structure, can easily perform a series of operations from measuring the size of the drainage holes in pots, to cutting wire to the precise length corresponding to that measurement, and then bending it into a uniform and highly accurate spectacle shape. [Solution] The device comprises a reference body 1, a slider 2 that is movable back and forth relative to the body, and a locking mechanism for fixing the slider's position. The body and slider are provided with a pair of semi-cylindrical bars, each consisting of a hole measuring bar 5, which protrudes downward. The hole measuring bar measures the diameter of the hole in the pot as the slider moves. In the measurement state using the hole measuring bar, the overall length of the jig structure corresponds to the required length of wire. Furthermore, the body and slider are provided with two wire-wound support columns 4 that protrude upward, serving as a reference for bending the wire into a spectacle shape.

Description

Technical Field

[0006] , , , ,

[0001] The present invention relates to a jig for bending a wire (wire rod) for fixing a net laid in a bottom hole of a flower pot or the like into a desired shape.

Background Art

[0002] In the flower pot industry, as a means of fixing a pot net (bottom net of the pot) laid on the bottom of the pot to the bottom hole of the pot, it is common to fix it using a wire (wire rod). Conventionally, when fixing this pot net, a fixing wire bent into a U-shape or glasses shape by handwork or using pliers has been widely used.

[0003] However, in the case of bending by handwork, it is necessary to cut out an appropriate length of wire depending on the size of the pot hole by relying on intuition, and it is easy to generate waste of excess wire and it is not economical.

[0004] Also, in handwork, it is difficult to uniformly align the bending size (fitting the hole diameter) and shape of the wire, and there is a problem that the forming work requires time and skill.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention has been made to solve the above-described conventional problems, and while having a simple structure, it can perform a series of operations from measuring the size of the pot hole to cutting out a wire of an accurate length corresponding thereto and bending it into a uniform and highly accurate glasses shape in a simple manner. The purpose is to provide a net retaining wire bending jig.

Means for Solving the Problems

[0006] The net retaining wire bending jig of the present invention includes a reference prismatic body, a hollow prismatic slider provided so as to be able to advance and retreat with respect to the body, and a locking mechanism. The locking mechanism is for fixing the moving position of the slider with respect to the body.

[0007] On the bottom of the body and the bottom of the slider, there are two semi-cylindrical bars that protrude downwards, forming a pair of measuring bars for measuring the diameter of the pot hole. By sliding the slider, the distance between the pair of semi-cylindrical bars is widened, and they come into contact with the inner wall of the pot hole. This makes it possible to directly measure the diameter of the pot hole.

[0008] In the measurement state using the pot hole measuring bar, the overall structural length of the jig is configured to correspond to the required wire length.

[0009] Furthermore, two wire-wrapped support columns are provided protruding upward from the upper surface of the body and the upper surface of the slider. These two wire-wrapped support columns serve as a reference for bending the wire into a spectacle shape.

[0010] The locking mechanism is not limited to the lever structure shown in the drawing. Various known mechanisms, such as screw-type or clamp-type mechanisms, can be used as long as they can fix and hold the slider's position. [Effects of the Invention]

[0011] According to this invention, by simply sliding the lower pot hole measuring bar to fit the actual pot hole diameter and operating the locking mechanism (lever) to fix the sliding mechanism, the overall length of the jig structure automatically matches the required wire length. Therefore, by simply cutting the wire along the total length of the jig, no unnecessary excess material is produced.

[0012] Furthermore, by simply placing the cut wire along the two upper wire winding supports and bending it in sequence while holding it down with your fingers, anyone can easily and uniformly form a stable, three-dimensional spectacle-shaped wire for securing the mesh, without requiring any special skills. [Brief explanation of the drawing]

[Figure 8] This is a perspective view showing a fixing wire that has been formed into a three-dimensional shape by bending a pair of loop sections downwards at a 90-degree angle relative to its base. [Figure 9] This is a schematic cross-sectional diagram showing the state in which the molded fixing wire is inserted into the drainage holes of the pot from above the pot bottom net and secured. [Modes for carrying out the invention]

[0014] Figures 1 and 3 are perspective views showing a wire bending jig for securing mesh according to one embodiment of the present invention. The jig comprises a standard rectangular prism-shaped body 1. A hollow rectangular prism-shaped slider 2 is fitted to the outer circumference of the body 1 so as to be able to move smoothly back and forth. A fixing lever 3 is provided on the side of the slider 2.

[0015] On the upper surface of the body 1 and the upper surface of the slider 2, there are projecting upwardly upright cylindrical wire winding struts 4 respectively. Also, on the bottom surface side of the body 1 and the tip bottom surface side of the slider 2, there are projecting downwardly upright pot hole measuring bars 5 each consisting of a pair of semi-cylindrical bars so as to face each other. These pair of semi-cylindrical bars 5 are designed such that in the state where the slider 2 is closed most, the flat surfaces thereof are joined together to form a single cylindrical form as a whole.

[0016] Figure 2 is a cross-sectional view of the locking mechanism as seen from the direction of arrow A in Figure 1. In the present embodiment, the lever 3 has an eccentric cam structure. By rotating the lever 3, the cam surface (blackened portion) clamps the internal member. Thereby, the moving position of the slider 2 is firmly locked and fixed with respect to the body 1.

[0017] The operation process when forming a wire for net pressing using this jig will be described. First, the pot hole measuring bar 5 located on the lower side is inserted into the pot hole of a potted plant pot or the like. The slider 2 is slid and widened, and the pot hole measuring bars 5 are brought into contact with the inner walls of the pot hole respectively. Thereby, the diameter of the pot hole is physically measured. At the position where the diameter of the pot hole is determined, the lever 3 on the side is operated to fix the moving position of the slider 2.

[0018] At this determined position, the overall structural length from end to end of the jig matches the exact length of the wire required to fit the pot hole. Therefore, a straight wire is aligned along the entire length of the jig and cut to match the length.

[0019] Next, as shown in Figure 4, the cut straight wire is placed through between the two wire winding struts 4 on the upper surface of the jig. One finger firmly holds and fixes the wire and the body (body 1 or slider 2) at the central portion.

[0020] As shown in Fig. 5, use the fingers of the other hand to bend it forward 180 degrees so that the wire runs along the outer periphery of one of the wire winding posts 4. Subsequently, as shown in Fig. 6, similarly bend the other side forward 180 degrees so that it runs along the outer periphery of the other wire winding post 4.

[0021] From the state where both sides are bent 180 degrees, further bend both ends of the thread one by one outward along the outer periphery of each wire winding post 4. As a result, as shown in Fig. 7, a pair of loops (ring-shaped parts) that go around the outer periphery of each wire winding post 4 are formed, and it becomes a planar glasses-like shape. In this state, pull out the wire above the jig and take it out.

[0022] Subsequently, as shown in Fig. 8, by bending the pair of loop portions 90 degrees downward (vertically downward) with respect to the central base, a three-dimensional fixed wire shape for holding the net is completed. At the time of manually bending 90 degrees, the width (interval) of the two parallel wires standing upright downward appropriately conforms to the inner diameter of the pot hole measured by sampling in advance.

[0023] Describe the final fixing process (laying method). As shown in Fig. 9, insert the formed fixed wire from above the net (bottom net of the pot) laid on the bottom of the pot so that a pair of legs straddle the pot holes. Then, at the opposite side of the pot hole (the back side of the bottom of the pot), bend and fix both ends (legs) of the wire so as to sandwich the net and the edge of the pot hole. As a result, the net is firmly crimped to the bottom of the pot and the fixing is completed.

[0024] In addition, in the above-described embodiment (drawing), a tightening structure using the lever 3 as a locking mechanism is exemplified, but the locking mechanism of the present invention is not limited to this. For example, various known locking mechanisms and fixing means that can reliably hold the moving position of the slider 2 with respect to the body 1, such as a truss screw or knob bolt method fixed by tightening a screw, a clamp lever method that can be engaged and disengaged with one touch, and a method of locking in multiple stages by irregularities (ratchet structure and pin insertion holes) provided on the slider and the body, can be widely adopted. [Industrial applicability]

[0025] This invention can be widely used as a tool for making fixing wires for the bottom net of pots in gardening, particularly in bonsai. [Explanation of Symbols]
