[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wire bending tool used for a so-called wire craft, which creates a wire model as a modified product expressing a motif or a pattern using a wire such as a wire.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a so-called wire craft that creates a wire model representing a motif, a pattern, or the like using a wire such as a wire has been performed. In wire craft, various tools such as pliers and metal scissors are used to bend, cut, or fix a wire.

[0003] Among the above-mentioned tools, there is a wire bending tool which can form various patterns by standing a pin on a table and bending a wire along the standing pin. FIG. 7 and FIG. 8 are a perspective view and a sectional view showing an example of the wire bending tool. As shown in the figure, the wire bending tool is provided with a fixed base 32 having a plurality of insertion holes 31 formed on the surface thereof, and is selectively inserted into each of the insertion holes 31 of the fixed base 32 to stand upright. And a pin 33.

[0004] The fixing base 32 is made of, for example, transparent acrylic, and is formed in a flat plate shape having a predetermined thickness. The insertion holes 31 are formed on the upper surface of the fixed base 32 so as to be arranged vertically and horizontally and regularly. The bottom of the insertion hole 31 is closed so that the pin 33 does not penetrate the fixing base 32. On the other hand, the pin 33 is formed in a round bar shape having a diameter slightly smaller than the inner diameter of the insertion hole 31, and an appropriate number of pins having the same size are prepared.

In order to create a wire model using this wire bending tool, first, as shown in FIG. 7, a paper P on which a design is drawn is laid under a fixing table 32. Next, the pin 33 is selectively inserted into an arbitrary insertion hole 31 to bend the wire W according to the design. Accordingly, the plurality of pins 33 are erected, and the wire W is continuously bent along the plurality of pins 33, whereby a wire model having a desired pattern can be created.

[0006]

[Problems to be solved by the invention]

 However, in the above-mentioned wire bending tool, the paper P on which the design is drawn is laid under the transparent fixed base 32. Therefore, there is a distance between the paper P on which the design is drawn and the upper surface of the fixed base 32 into which the pins 33 are actually inserted, by the thickness of the fixed base 32. Therefore, in order to insert the pin 33 accurately in accordance with the design, the design must be viewed from directly above the fixed base 32 and the design must match the insertion insertion hole 31 of the pin 33. Also, when bending the wire W, it may be necessary to look into the design from directly above the fixing base 32 in the same manner as described above, in order to confirm whether the bending state of the wire W matches the design. Therefore, it was difficult to say that this wire bending tool had good workability.

[0007]

[Disclosure of Invention]

 The present invention was devised in view of the above circumstances, and has as its object to provide a wire bending tool that can further improve the workability when creating a wire modeled object. .

In order to solve the above problems, the present invention takes the following technical measures.

A wire bending tool provided by the first aspect of the present invention has a fixed base having a plurality of insertion holes formed on an upper surface, and is selectively inserted into the insertion holes and erected on the fixed base. A wire bending tool for forming a wire object by bending a wire along the pins, the wire bending tool comprising one or more pins, and one end of the pin is formed in a pointed shape. Things.

[0010] Here, in the conventional configuration, the paper is laid under the fixed base and the pins are inserted. Therefore, there is a space between the paper on which the design is drawn and the upper surface of the fixed base where the pins are actually inserted. Due to the distance, it was difficult to insert the pins correctly according to the design and to check the bending of the wire according to the design. However, according to the configuration of the present invention, one end of the pin inserted into the insertion hole of the fixing base is formed in a pointed shape. Therefore, for example, if the paper with the design is placed on the surface of the fixed base, the pin can be inserted directly into the paper on which the design is drawn, and the actual insertion position of the pin and the position to be inserted according to the design are determined. Can be matched exactly. In addition, when bending a wire, it is possible to directly match the degree of bending of the wire with the design drawn on the paper. Therefore, the wire can be reliably bent according to the design. Therefore, according to the invention of the present application, it is possible to further improve the workability when creating a wire structure, and to accurately create the wire structure as illustrated.

According to a preferred embodiment of the present invention, a stepped head is formed at the other end of the pin. According to this, when the pin is inserted into the insertion hole of the fixing base, the stepped head of the pin abuts and locks near the periphery of the insertion hole of the fixing base. For example, when the paper is placed on the fixed base, when inserting the pins into the insertion holes, the pin body penetrates the paper, but the stepped head comes into contact with the surface of the paper. At this time, even if the insertion hole penetrates the fixed base, the pin is supported by the fixed base without penetrating by the stepped head. Therefore, the paper can be securely fixed on the fixed base.

In addition, as described above, if the pin is locked to the fixed base by the stepped head of the pin, after the wire bending operation is completed, the paper is inserted by lifting the paper upward. The plurality of pins can be removed from the insertion hole of the fixed base at a time while being locked on the paper. Therefore, it is possible to save the trouble of removing the pins one by one from the insertion holes one by one, and it is possible to further improve the workability.

According to another preferred embodiment of the present invention, the stepped head is formed in a substantially cylindrical shape, and a plurality of types of pins are prepared depending on the diameter of the stepped head. Thus, if the wire is bent using stepped heads having different diameters, various bent portions having different radii of curvature can be created. Therefore, it is possible to create wire shaped objects of various shapes.

The stepped head may be formed in a substantially polygonal column shape. Thus, if the wire is bent using the stepped head having a substantially polygonal prism shape, a wire model having a bent portion having a different shape can be created.

According to another preferred embodiment of the present invention, the fixing base comprises a frame member having a hollow portion, and a panel member provided on an upper surface thereof and having an insertion hole formed therein. As described above, if the hollow portion is formed in the frame-shaped member, the material of the fixing base can be reduced, and the weight can be further reduced. Therefore, it is possible to provide a wire bending tool which can reduce the cost of parts and is easy to handle.

According to another preferred embodiment of the present invention, the surface of the fixing base is white or a light color close to white. Thus, if the surface of the fixing base is white or a light color close to white, when paper is placed on the fixing base, an insertion hole is formed when the fixing base is visually recognized from above. The part that is present and the part that is not formed become clearer. Therefore, for example, when the operator inserts the pin from above the paper, the position of the insertion hole can be immediately recognized through the paper, so that the work can be performed efficiently.

According to another preferred embodiment of the present invention, the frame-shaped member is formed such that an intermediate portion of each side is depressed inward and curved in a plan view. In this way, if the middle part of each side of the frame-shaped member is depressed inward and curved, it is easy for the operator to hold the wire bending tool when moving the wire bending tool, and the wire bending tool is easy to use.

[0018] Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

[0019]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a fixing base of the wire bending tool according to the present invention. FIG. 2 is a sectional view showing the fixing base shown in FIG. FIG. 3 is a perspective view showing a pin of the wire bending tool. This wire bending tool is used for a so-called wire craft, in which a wire model is formed as a modified product by bending a wire into a desired shape. That is, as shown in FIGS. 1 to 3, the wire bending tool is provided with a fixed base 12 having a plurality of insertion holes 11 formed therein, and selectively inserted into the insertion holes 11 to stand on the fixed base 12. It is composed of a plurality of pins 13 and bends the wire along the pins 13 to create a wire model.

The fixed base 12 is formed in a substantially square shape in plan view, and includes a frame-shaped member 15 having a hollow portion 14 and a flat panel member 16 integrally formed on the upper surface thereof. The frame member 15 and the panel member 16 are made of a resin such as plastic. The frame member 15 is formed such that each side is smoothly curved in a cross-sectional view, and an intermediate portion 15a of each side is formed in a plan view. It is formed so as to be depressed inward and curved.

As described above, if the intermediate portion 15a of each side of the frame-shaped member 15 is depressed inward and curved, the operator can easily hold the wire bending tool when moving it. In addition, since the hollow portion 14 is formed in the frame member 15, the material of the fixing base 12 can be reduced, and the weight can be further reduced. Therefore, there is an advantage that parts cost can be reduced and the parts can be easily moved. A pedestal made of rubber or the like may be provided at the bottom of the frame-shaped member 15 so that the wire is not easily shifted when a wire is processed by an operator. Further, the frame-shaped member 15 is not limited to the above configuration, and the hollow portion 14 may not be formed.

The panel member 16 is formed in a substantially square shape slightly smaller than the outer shape of the frame-shaped member 15 and has a predetermined plate thickness. A plurality of insertion holes 11 penetrating in the thickness direction are formed in the panel member 16 so as to be regularly and vertically arranged. The inner diameter of the insertion hole 11 is slightly larger than the outer diameter of the pin 13, that is, the insertion hole 11 is formed in such a size that the pin 13 can be smoothly inserted into and removed from the insertion hole 11. As described above, since the insertion hole 11 is formed so as to penetrate the panel member 16, it can be easily formed by injection molding.

The surface of the panel member 16 is white. As described above, if the surface of the panel member 16 is made white, the insertion hole 11 of the panel member 16 is formed even when the paper on which the design is drawn is placed on the upper surface of the panel member 16, for example. The portions that are not formed and the portions that are not formed are visually recognized so as to be clearer. Therefore, for example, when the operator inserts the pin 13 from above the sheet, the position of the insertion hole 11 can be immediately recognized, and the operation can be performed efficiently. The color of the surface of the panel member 16 is not limited to the white color described above, but may be any bright color close to white, and is not particularly limited as long as the position of the insertion hole 11 becomes clear.

The panel member 16 may be formed separately from the frame member 15, and may be detachable from the frame member 15. By making the panel member 16 detachable in this manner, for example, another panel member having an insertion hole with a small diameter or an insertion hole with a smaller pitch between adjacent insertion holes can be attached. Therefore, if the other panel member is used, a wire model having a finer pattern can be produced. Further, the panel member 16 in the present embodiment does not need to be made transparent as in the conventional configuration.

The pin 13 has a main body 18 formed of, for example, a stainless steel bar. The length of the main body 18 is formed to be larger than the length of the insertion hole 11, and the diameter of the main body 18 is , Are slightly smaller than the diameter of the insertion hole 11. One end 18a of the main body 18 is formed in a pointed shape. Specifically, one end 18a of the main body 18 is formed in a sharp shape so that it can penetrate the paper on which the pattern of the wire model is drawn, and the hole of the penetrated paper does not greatly widen.

In the conventional configuration, the paper is laid under the fixed base and the pins are inserted. Therefore, a distance is generated between the paper on which the design is drawn and the position where the pins are to be inserted. It was difficult to insert the pin accurately. However, as described above, if one end of the pin 13 inserted into the insertion hole 11 of the fixing base 12 is formed in a pointed shape, for example, the paper on which the pattern is drawn is placed on the upper surface of the fixing base 12. Then, the pins 13 can be inserted directly into the paper on which the design is drawn. Therefore, the actual insertion position of the pin 13 and the position to be inserted according to the design can be accurately matched. Also, when bending the wire, the bending can be performed while directly checking the degree of bending of the wire and the design drawn on the paper P. Therefore, the workability when creating a wire object can be further improved, and the wire object can be created more accurately as designed.

On the other hand, the other end 18 b of the main body 18 is formed with a substantially cylindrical stepped head portion 20 having a diameter larger than the diameter thereof. That is, a plurality of pins 13 are prepared, and more specifically, a plurality of pins 13 are prepared depending on the diameter of the stepped head 20 formed at the other end 18b of the main body of the pin 13. For example, as shown in FIGS. 4A to 4C, the diameter of the stepped head 20 is divided into three types, large, medium, and small. Divided. The number of types of the pins 13 is not limited to the above three types.

As described above, if a plurality of types of pins 13 are prepared depending on the diameter of the stepped head 20, if the wire is bent using the stepped heads 20 having different diameters, the radius of curvature will be different. Various bent parts can be created. For this reason, the shape of the wire model becomes more versatile, and the variation of the wire model can be given a wide range. The stepped head 20 of the pin 13 is not limited to a substantially columnar shape, and may be formed in a substantially polygonal column shape, for example. This also makes the shape of the wire model more versatile.

Next, a wire processing method using the wire bending tool will be described. In this wire processing method, unlike the conventional bending method, a paper P on which a design is drawn is placed on the upper surface of the fixed base 12 as shown in FIGS. In this case, the end of the paper P may be fixed with an adhesive tape or the like so that the paper P does not slide down on the fixed base 12, or the pin 13 may be inserted through the insertion hole 11 at the peripheral edge of the paper. The paper P may be stopped by inserting it into the paper P.

The paper P is made of a material such that a plurality of insertion holes 11 formed on the upper surface of the fixed base 12 can be seen through to see the design, and a large hole is not formed even if the paper P is penetrated by the pin 13. It is sufficient if the sheet has the following properties: copy paper or the like generally used for general purposes. Preferably, a ruled line or the like according to the arrangement of the insertion holes 11 of the fixing base 12 may be drawn on the sheet. In this way, when inserting the pin 13, the position of the insertion hole 11 can be easily determined, and workability is further improved.

Next, the operator inserts the pins 13 into the paper P according to the design copied or printed on the paper P. At this time, the main body 18 of the pin 13 penetrates the paper P and is inserted into the insertion hole 11 of the fixing base 12. On the other hand, the stepped head 20 is in contact with the surface of the sheet P near the periphery of the insertion hole 11. That is, the pin 13 is supported by the stepped head 20 without penetrating the insertion hole 11, and the paper P can be fixed on the fixing base 12.

When the plurality of pins 13 are inserted into the insertion holes 11 of the fixing base 12 and erected as described above, next, along the erected pins 13, specifically, a stepped head The wire W is bent along the shape of the side surface 20a of 20 to create a wire model having a desired shape. In this embodiment, since a plurality of types of pins 13 having different diameters of the stepped head portion 20 are prepared, it is possible to create a wire model in which the bent portion is formed in various shapes.

After the wire model is formed into a desired shape, it is moved above the fixing base 12 and removed from the pin 13. Subsequently, the pins 13 are removed from the insertion holes 11. In this case, the pins 13 are not lifted one by one from the insertion holes 11, but are lifted upward while the paper P is kept parallel. To In this way, the inserted pins 13 are pulled out of the insertion holes 11 of the fixed base 12 at a time while being locked with the paper P. Therefore, it is possible to save the trouble of removing the pins 13 one by one from the insertion holes 11 one by one, and it is possible to further improve the workability.

Of course, the scope of the present invention is not limited to the embodiment described above. For example, the shape, the material, the number of the insertion holes, the size of the insertion holes, the arrangement of the insertion holes, and the like of the fixing table are not limited to the above-described embodiment. Further, the shape and material of the pin are not limited to the above-described embodiment.
