BACKGROUND OF THE INVENTION
The present invention relates to a hand tool and an auxiliary tool for a hand tool for creating a handicraft with a spiral wound by winding an elongated strip of paper around the tip.
[0002]
[Prior art]
For example, there is a handicraft called “Quilling”, and a long strip of paper called “quilling paper” is spirally wound using a hand tool 1 called a needle tool as shown in FIG. Creating a component.
The hand tool 1 has a thin cylindrical needle 3 fixed to the tip of a long and thin main body 2 having a cylindrical shape. A split groove 3a is formed at the tip of the needle 3, and the split groove 3a is formed in the split groove 3a. A part 5 is created by sandwiching one end of the belt 4 and winding it around the needle 3 (see FIG. 9).
The part 5 created in this manner is fixed by placing it on a mount or the like by adjusting the outer shape by holding the winding end part with an adhesive and pressing it with a finger or the like. A work is produced by creating a large number of parts 5 and arranging them appropriately on the mount.
[0003]
[Problems to be solved by the invention]
However, the conventional apparatus as described above has the following problems. That is, first, since the hand tool 1 has a relatively thick needle 3 (for example, a diameter of about 1.3 to 5 mm), the work to be manufactured is as shown in FIG. In addition, since a portion 5a larger than the diameter of the needle 3 is formed in the central portion, it is impossible to make a beautiful ideal part 6 (see FIG. 5B) that is packed up to the central portion 6a at the beginning of winding.
[0004]
This first problem can be solved by simply making the needle 3 thinner, but if the needle 3 is made thinner, another technical problem will occur. That is, when the diameter of the needle 3 is reduced, the insertion dimension of the belt-like paper 4 is reduced when the needle 3 is inserted into the dividing groove 3a, and thus it is easy to come off at the start of winding. For this reason, it is conceivable that the width dimension of the dividing groove 3a is also narrowed to make it difficult to remove the belt-like paper 4. This makes it difficult to insert the strip 4 into the split groove 3a. As a result, it takes time and labor to manufacture one component, and the efficiency is lowered.
[0005]
Secondly, with the hand tool 1 having the conventional configuration, as shown in FIG. 9, even when there is no problem for an experienced worker, the belt 4 is wound around the tip of the needle 3. It is necessary to roll the paper 4 while holding it with a finger so that it does not come off, and this is an operation that requires advanced techniques for those who are not used to it, such as beginners, and those who are not dexterous.
[0006]
The handicraft called quilling is not yet well known in Japan. In other words, there are many beginners who use this hand tool 1, and in that sense, handling of the hand tool 1 requires high technology. For this reason, they sometimes quit before learning advanced techniques to finish their work, which is a factor that hinders their spread.
Even beginners can easily handle it, and if they can finish beautiful works, the interest of many people will increase, so it will be possible to contribute to the spread. Even in that case, it is necessary to avoid that the hand tool 1 itself has a complicated configuration or becomes expensive. In addition, when the wrapping operation of the belt 4 is used, it is possible that the operator will not be disturbed even by the method shown in FIG. 9, and it is desirable that this point be taken into consideration. Is.
[0007]
The present invention has been made in view of the above circumstances. The purpose of the present invention is to enable easy loading of a band-shaped paper even when the needle portion has a small diameter, without being detached at the beginning of winding, and to quickly perform the work. It is an object of the present invention to provide a hand tool and an auxiliary tool that can make a beautiful part full of parts and that can be handled easily even by beginners at low cost.
[0008]
[Means for Solving the Problems]
According to the first aspect of the present invention, the winding body is fixed to the distal end portion of the main body having an elongated cylindrical shape, the front end of the elongated strip-shaped paper is sandwiched between the slits formed in the winding body, and the main body portion is rotated. By doing so, you can wind the belt. At this time, since the split groove of the wound body is formed so as to be wide at the tip and narrow at the bottom of the groove, in addition to being easy to put when sandwiching the strip paper in the split groove, The paper is less likely to come off, improving the efficiency of workability, and even a beginner can easily perform the work of winding a belt. In addition, when used in a state where the winding body is inserted through the through hole of the auxiliary tool, the main body can be rotated with the tip side of the hand tool held by the fingertip, so that stable winding work is performed. Will be able to. Especially for beginners, it is easy to use because the belt-like paper wrapped around can be held flat.
[0009]
According to the invention of claim 2, since the split groove of the winding body is formed so as to be narrow at the mounting portion where the winding work is widely performed at the insertion portion, and the groove width changes stepwise or continuously, It is easy to insert paper, and in a state where it is mounted at the mounting portion, it is possible to make it difficult to come off when winding, so that the usability can be improved. In this case, whether to change it stepwise or continuously may be appropriately selected according to the ease of processing, the quality and thickness of the belt-like paper used, or the user's preference.
[0010]
According to the invention of claim 3 , since the support portion is provided to be rotatable at the base end portion of the main body portion, when the winding operation is performed, the support portion is applied to the palm of the hand to rotate the main body portion. Since the support portion can rotate only the main body portion while being fixed by the palm, the winding operation can be performed in a stable state.
[0011]
According to the invention of claim 4, since the main body portion has a chuck portion that detachably holds the wound body at the tip portion, various wound bodies are prepared and used for replacement. As a result, it is not necessary to have a structure in which the wound body and the main body are integrally formed to make a work, so that a plurality of types of wound bodies can be used at a low cost. .
[0012]
According to invention of Claim 6, when using the hand tool of Claims 1 thru | or 5, the front end side of the hand tool was fixed with the fingertip by using the wound body inserted through the through hole. Since the main body can be rotated in a state, a stable winding operation can be performed. Especially for beginners, it is easy to use because the belt-like paper wrapped around can be held flat.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. ◎
As shown in FIG. 1, a needle tool 11 that is a hand tool for quilling includes a main body portion 12 and a needle 13 that is a wound body. The main body portion 12 has a configuration having a chuck portion 14 so that the needle 13 can be fixed to the distal end portion, and has a configuration such as a so-called precision screwdriver or a small pin vise.
[0014]
In other words, it has a generally cylindrical shape, and the chuck portion 14 is a screw type, and can be fixed by the chuck when the needle 13 is inserted and rotated. A large number of grooves 12a along the axial direction are formed in the grip portion of the main body portion 12, and are configured not to slip when rotated by hand.
As described above, the needle 13 is detachably fixed to the main body portion 12 by the chuck portion 14, so that it can be replaced with various needles 13 as necessary. By changing the diameter of the needle 13 in this way, it is possible to enrich the variations of the work.
[0015]
A holding portion 15 attached to the base end portion (end portion) of the main body portion 12 so as to be rotatable around an axis is provided. The holding portion 15 is formed in a shape that does not feel pain or pain to the palm even when a long-distance operation is performed so that it can be easily received and held by the palm when held by hand. Moreover, the groove part 15a is formed radially so that it may not slip when it is received by the palm.
[0016]
FIG. 2 shows an enlarged view of the needle 13 having a diameter of, for example, 1.0 mm, 0.8 mm or less. The needle 13 is made of a hard metal, has a flat shape at the tip end side, and is formed with a split groove 16 so as to divide it into two, and a base end portion side is formed in a cylindrical shape. The split groove 16 is formed to be wide on the distal end portion 16a side and narrow on the proximal end portion side. In this case, a portion where the split groove 16 at the front end is wide is set so that a quilling paper 17 (see FIG. 4) which is a strip-shaped paper can be easily attached as will be described later. The paper 17 is set so as to be difficult to come off during the winding work.
[0017]
FIG. 3 shows, for example, three types of auxiliary tools 18, 19, and 20 that are used by being attached to the needle 13. The auxiliary tool 18 has a cylindrical shape as shown in FIG. 1A, and a through hole 18a is formed in the center so that the needle 13 can be inserted. Similarly, the auxiliary tool 19 is formed in a disk shape as shown in FIG. 2B, and is formed with a through hole 19a. As shown in FIG. 2C, the auxiliary tool 20 has a composite shape in which a disk-shaped member 20a and a cylindrical member 20b are combined, and a through hole 20c is formed.
[0018]
Next, how to use the needle tool 11 and the auxiliary tools 18 to 20 will be described. Here, the case where the auxiliary tools 18-20 used as a means effective for the beginner and the unfamiliar person about quilling is demonstrated centering on.
First, the through hole 18 a of the auxiliary tool 18 (or the auxiliary tools 19 and 20) is inserted into the needle 13 portion of the needle tool 11. In this state, the split groove 16 portion which is the tip portion of the needle 13 is in a state of protruding to the outside through the through hole 18a.
In this state, as shown in FIG. 4, a quilling paper 17 that is a belt-like paper is attached. First, as shown in FIG. 2A, the quilling paper 17 is inserted into the wide end portion 16a of the split groove 16. After that, the quilling paper 17 is inserted deeply into the base end portion 16b side where the width of the split groove 16 is narrow. At this time, the quilling paper 17 is mounted while being pulled slightly so that the tip of the quilling paper 17 is kept short so as not to come out of the split groove 16.
[0019]
Next, as shown in FIG. 5, the holding part 15 is pressed against the palm of the right hand RH, and the main body part 12 is held in a state where it can be turned with a finger. The left hand LH holds the tip of the needle 13 while pressing the quilling paper 17 with a fingertip so as not to loosen. In this state, when the main body 12 is rotated as indicated by the arrow P with the finger of the right hand RH, the quilling paper 17 attached to the tip of the needle 13 is wound. In this case, the winding direction can be performed in the direction opposite to the arrow P, or the winding may be performed in any convenient direction.
When it is wound for a predetermined length, a part with a curl (see FIG. 10B) is completed by extracting the needle 13. Since the needle 13 is thin, it is possible to obtain a finished part having a beautiful shape packed to the center.
[0020]
FIG. 6 shows a state where the winding operation is performed using the auxiliary tool 20 in the same manner. In this case, the way of holding the left hand LH is slightly changed, but the holding method of the needle 13 and the pressing method of the quilling paper 17 are substantially the same. These auxiliary tools 18 to 20 can be appropriately used depending on various conditions such as the convenience of the user, the size of the parts to be produced, the width of the quilling paper 17 to be used, and the paper quality.
[0021]
And by using the auxiliary tools 18-20 in this way, the holding of the quilling paper 17 attached to the tip of the thin needle 13 can be made simple and reliable, and even for beginners and unfamiliar people. The quilling paper 17 can be wound quickly.
Further, since the split groove 16 formed in the distal end portion of the needle 13 is set to have a stepwise changing width dimension between the wide distal end portion 16a and the narrow proximal end portion 16b, the needle 13 has a small diameter. Even when using the quilling paper 17, it is possible to easily attach the quilling paper 17, and it is possible to reliably perform the winding operation by sandwiching the quilling paper 17.
[0022]
FIGS. 7A, 7B, and 7C show another embodiment of the present invention. In FIG. 5A, the needle tool 21 uses the same main body 22 as that of the conventional type. The needle 23 fixed to the distal end portion has a split groove 24 formed with a constant width dimension, and only the distal end portion 24a is cut into a tapered shape. Even in the case where the needle 23 having such a shape is used, the quilling paper 17 can be easily and quickly attached as in the above-described embodiment.
[0023]
In FIG. 2B, the needle tool 25 has a needle 26 attached and fixed to the main body 22. The split groove 27 of the needle 26 is formed so that the width dimension changes stepwise. Moreover, in the same figure (c), the needle tool 28 mounts and fixes the needle 13 currently used by embodiment mentioned above to the main-body part 22. FIG. Also with these needle tools 25 and 28, the same operational effects as the needle tool 21 can be obtained.
[0024]
The present invention is not limited to the above embodiment, and can be modified or expanded as follows.
The split groove may be configured to have a stepwise change in width dimension of three or more stages.
The shape of the assisting tool is not limited to the shape of a cylinder, a disk, or a combination thereof, but may be a rectangular shape or a shape that follows the shape of the finger so that it can be easily held by the fingertip.
[0025]
The auxiliary tools 18, 19, and 20 can employ a configuration that can be fixed to the main body portion 12 so that the auxiliary tools 18, 19, and 20 can rotate integrally with the main body portion 12 of the needle tool 11 when mounted on the needle tool 11. As a result, the workability of winding the quilling paper 17 can be improved.
Contrary to the above, the auxiliary tools 18, 19, and 20 can be configured to be rotatably mounted on the main body portion 12 when mounted on the needle tool 11. Thereby, only the rotation can be freely performed without moving the auxiliary tools 18, 19, and 20 in the axial direction, so that the workability of winding can be improved. It should be noted that these detachable configurations can be adopted by appropriately selecting a user-friendly one. The cross section of the needle may be circular or elliptical, and an appropriate shape can be set.
