Description

  The present invention relates to a wire drawing tool for performing wire drawing with a colored liquid or powder adhered to a thread in woodworking or construction.

  As drawing tools used in woodworking and construction, traditionally, ink brushes that draw with colored ink such as sumi ink, and choke lines that draw with yarn that adheres powder such as chalk powder, etc. What is called is known.

  For example, the ink brush has a built-in ink penetrating member that attaches ink to the bobbin and the thread drawn from the bobbin, and a chalcone that attaches to the tip of the thread by sticking it to any part of the construction target material. It is a thing. In order to draw a black line using this ink brush, first, the calco is fixed to one drawing reference point of the construction target material, and then the body is moved toward the other drawing reference point. At this time, since the ink sticks to the thread drawn from the spool by contact with the ink penetrating member, the thread pressing surface formed on the thread drawing portion of the body is pressed against the other drawing reference point on the surface of the construction target material. Thus, in a state where an appropriate tension is applied to the yarn between the calco and the body, the linear ink line can be transferred by flicking the yarn toward the surface of the construction target material with fingers.

The body 1 includes a circular bobbin storage portion 11, a front ink chamber forming portion 12, a front thread outlet portion 13, and a bobbin cover 14 detachably provided at an upper opening of the bobbin storage portion 11. And an ink chamber cover 15 provided at the upper opening of the ink chamber forming portion 12 through a hinge 151 so as to be swingable.

  As shown in FIG. 3, the bobbin cover 14 is detachably fixed to the opening edge of the bobbin storage unit 11, so that a bobbin winding chamber 1 </ b> A that rotatably holds the bobbin 2 is interposed between the bobbin storage unit 11. It is what defines. The bobbin 2 includes a bobbin body 21 that winds the thread 3 around the outer periphery, and a spiral spring 22 that is attached to the inner periphery of the bobbin body 2 and biases the bobbin body 21 in the winding direction of the thread 3. One end of the direction is exposed from the inner periphery of the bobbin cover 14 to the outside. The bobbin 2 can be taken out of the bobbin winding chamber 1A by removing the bobbin cover 14 from the bobbin storage part 11.

  The ink chamber cover 15 has an engagement hook 152 (see FIG. 1) formed on the outer surface of the ink chamber forming portion 12 with an engagement hole 152 (see FIG. 1) formed at the swing end portion (the end opposite to the hinge 151). By being engaged with 121, the upper opening of the ink chamber forming portion 12 can be fixed in a closed state.

  The ink chamber cover 15 is provided with a packing 153 made of a rubber-like elastic material (rubber material or synthetic resin material having rubber-like elasticity), and can be in close contact with the upper surface of the ink chamber forming portion 12. The ink chamber 1B defined by the ink chamber forming portion 12 and the ink chamber cover 15 is made of sponge, absorbent cotton, felt, or the like, and preferably ink ink made of cellulose fibers having an excellent ink penetrating and retaining action. The penetrating member 4 is detachably accommodated. Further, a push button 154 is formed on the packing 153 of the ink chamber cover 15, and a press member 155 made of a synthetic resin material is attached to the inner surface of the push button 154. The ink is equivalent to the coloring material described in claim 1, and the ink infiltration member 4 and the ink chamber 1B are equivalent to the coloring material holding part described in claim 1.

  In the state where the ink chamber cover 15 is closed, the pressing member 155 is pushed down by pushing the push button 154 with a finger to be depressed, and the upper surface of the ink penetrating member 4 is pressed and compressed. The thread 3 is pushed down at both ends. Further, when the pressing of the push button 154 by the finger is released, the pressing member 155 is restored by the restoring force of the push button 154 having rubber elasticity.

  The yarn lead-out portion 13 is formed so as to surround the funnel-shaped lead-out port 1 </ b> C continuous from the yarn insertion portion, and its end surface 13 a is relative to a plane orthogonal to the central axis of the ink chamber forming portion 12 and the yarn lead-out portion 13. The upper half of the end surface 13a is a semicircular thread pressing surface 131 for pressing the thread 3 pulled out from the outlet 1C against the mating member. An anti-slip member 5 is provided at the bottom position of the end face 13a, that is, the end edge opposite to the direction in which the yarn 3 is stretched from the outlet 1C. In addition, a plurality of guide grooves 131a are formed in the thread holding surface 131 at appropriate intervals.

  The anti-slip member 5 is made of a rubber-like elastic material (rubber material or a synthetic resin material having rubber-like elasticity), and easily slips into the mounting recess 132 formed at the bottom position of the end surface 13a of the yarn lead-out portion 13. The outer surface is slightly raised from the end surface 13 a of the yarn lead-out portion 13.

  The yarn 3 wound around the bobbin main body 21 of the bobbin 2 is pulled out from the thread insertion portion between the bobbin chamber 1A and the ink chamber 1B, the slit formed in the ink infiltration member 4 in the ink chamber 1B, and the ink chamber 1B. The yarn is led out from the outlet 1C to the outside of the body 1 through a thread insertion portion between the mouth 1C.

  Reference numeral 6 is a spring charger. The spring charger 6 is provided with a one-way clutch means and a releasing means for adjusting the biasing force of the spiral spring 22 built in the bobbin 2 as desired.

  A chalcone 7 is connected to the tip of the thread 3 led out of the body 1 from the outlet 1C. As shown in FIG. 4, the chalcone 7 includes a synthetic resin hollow handle 71 and a metal fastening needle 72 detachably attached to the handle 71. The fastening needle 72 is housed in the handle 71 by a spring (not shown), and can be pushed out of the handle 71 against the urging force of the spring by pressing the pressing piece 73 in use. ing. Further, the tip 71a of the handle 71 is formed in a shape that can be held in a fitted state in the drawer port 1C.

  The ink fountain configured as described above is sufficiently impregnated with ink in the ink infiltration member 4 in the ink chamber 1B in advance. The ink infusion penetrating member 4 can be impregnated with the ink by opening the ink chamber cover 15 and injecting the ink into the ink chamber 1B.

  In the inking (drawing) operation by the ink brush, as shown in FIG. 4, the chalcone 7 is pressed by the pressing piece 73, and the fastening needle 72 is pressed by one of the inking marks on the surface of the construction target material W made of wood or the like. When the body 1 is moved toward the other reference point P2 for inking after the puncture at the reference point P1, the thread 3 is pulled out by the moving distance of the body 1 while the spool 2 is rotated. Go. Ink sticks to the thread 3 by slidingly contacting the ink penetrating member 4 in the process of being pulled out. Further, the spiral spring 22 incorporated in the bobbin 2 is wound and stored with the rotation of the bobbin main body 21.

  When the body 1 is moved to the other reference point P2 for blacking, the thread 3 is held at the reference point P2 on the surface of the construction target material W by the thread retainer 131 at the tip of the thread lead-out portion 13 of the body 1. Then, the yarn 3 drawn out from the draw-out port 1C is appropriately stretched between the chalcone 7 which is stuck to the reference point P1 through an arbitrary guide groove 131a in the yarn presser 131 of the yarn lead-out portion 13.

  At this time, although the tension of the yarn 3 acts on the yarn lead-out portion 13 of the body 1, the anti-slip member 5 made of a rubber-like elastic material provided at the bottom position of the end surface 13a of the yarn lead-out portion 13 is attached to the construction target material W. By pressing against the surface, sliding of the yarn lead-out portion 13 due to the tension is suppressed. Further, since the anti-slip member 5 slightly protrudes from the end surface 13a of the yarn lead-out portion 13, the guide in the yarn presser 131 of the yarn lead-out portion 13 with the anti-slip member 5 pressed against the surface of the construction target material W as a fulcrum. The position of the groove 131a can be finely adjusted to the left and right, and is prevented from slipping at a position close to the outlet 1C, so that the operation of positioning and fixing the drawer end of the yarn 3 to the reference point P2 can be easily performed.

  Next, by pulling the thread 3 once with a finger so that it floats from the surface of the construction target material W and then releasing the finger, the thread 3 adheres to the thread 3 if it is struck against the surface of the construction target material W by tension. A straight ink line can be transferred by the ink. Then, in the process of pulling the thread 3 once with the fingers so as to float from the surface of the construction target material W, the tension of the thread 3 increases. Again, the anti-slip member 5 is pressed against the surface of the construction target material W. Therefore, it is possible to prevent the leading end portion of the yarn 3 from deviating from the reference point P2 and to draw an accurate black line.

  After completion of the inking operation, when the body 1 is moved toward the calco 7 fixed at the reference point P1, the bobbin 2 is rotated in the winding direction by the spiral spring 22 accumulated in the process of pulling out the yarn 3. Therefore, the yarn 3 is automatically wound around the bobbin main body 21. Finally, when the chalcone 7 is pulled out from the construction target material W, the yarn 3 is further wound up, and the chalcone 7 is locked to the drawer port 1C in a semi-contained state.

  Since the anti-slip member 5 is detachable, if there is wear or material deterioration due to repeated use of the ink brush, it can be replaced with a new one.

  In the above-described embodiment, the anti-slip member 5 is provided at the bottom position of the end surface 13a of the yarn lead-out portion 13, that is, at the position opposite to the tensioning direction of the yarn 3 from the outlet 1C. Of the end face 13a, a semi-circular thread pressing surface 131, that is, located at the edge of the thread 3 extending direction from the outlet 1C, and the thread pressing surface 131 is directly prevented from slipping, or It is conceivable that the anti-slip member 5 is provided at both positions, or that the entire end surface 13a is made of an anti-slip member.

  Further, the anti-slip member 5 is not limited to one made of a rubber-like elastic material, and may be one whose friction coefficient is increased by roughening, for example.

  Further, in the above-described embodiment, the case where the drawing tool is the ink brush has been described. However, the drawing tool is called a choke line that draws a line with a powder, such as chalk powder, attached thereto, and draws the yarn from the body. The same applies to some cases.
