Description

  TECHNICAL FIELD The present invention relates to an ink brush that draws lines for construction and various operations with a thread to which ink is attached in woodwork or construction work.

  2. Description of the Related Art Ink brushes are widely known as tools for drawing a straight line on the surface of a construction target material such as wood in woodworking or construction work. This ink brush has a built-in ink penetrating member that attaches the ink wound to the spool and the thread drawn from the spool, and a chalcone that attaches to the tip of the thread by sticking it to any part of the construction target material. It is what was done.

  In other words, in order to draw a black line using this ink brush, first, the charco is fixed to an arbitrary ink starting point of the construction target material, and then the main body of the ink brush is moved, whereby the yarn is pulled out from the spool and this yarn is drawn. In addition, since the ink sticks due to contact with the ink penetrating member, with a suitable tension applied to the thread, the thread is brought into contact with the surface of the construction target material with a finger to bring the thread into contact. Ink lines can be transferred. A typical prior art of this type of ink candy is disclosed in the following patent document.

  However, as disclosed in the patent document, the conventional ink brush is designed to press the yarn drawn from the spool against the ink penetrating member with the press rod, so that the ink contacts the ink penetrating member over a long range. For this reason, if the amount of ink impregnation of the ink penetrating member is reduced to some extent by repeating the ink line drawing operation, it is difficult for the ink to adhere to the thread and it may be difficult to draw a clear ink line.

  Further, since the ink penetrating member is compressed as the thread is pressed against the ink penetrating member by the pressing rod, if the ink penetrating member is impregnated with a sufficient amount of ink, a large amount of ink is oozed out by the compression. As a result, there is a possibility that a part of the ink juice leaks out from the threading hole of the ink jet main body.

JP 2004-25390 A JP 2009-83067 A

  The present invention has been made in view of the above points, and the technical problem is that even if the amount of ink impregnation of the ink infiltration member is reduced, the ink is sufficiently adhered to the yarn and is clear. The purpose of the present invention is to make it possible to draw a black line and to prevent as much as possible leakage of the ink that has oozed out when the yarn is brought into contact with the ink penetrating member.

  As a means for effectively solving the technical problem described above, the ink brush according to the invention of claim 1 is formed with an ink chamber in which the ink penetrating member is accommodated in the ink brush main body in which the spool is built. A pressing member capable of advancing and retreating in the ink chamber is provided, and a slit through which the thread drawn from the spool is passed is formed in the ink penetrating member, and the pressing member has a portion that presses only the thread, The yarn in the slit is displaced in the depth direction of the slit.

  According to a second aspect of the present invention, there is provided an ink brewery according to the first aspect of the invention, wherein the pressing member has an ink penetrating member pressing portion that presses the ink penetrating member.

  According to a third aspect of the present invention, there is provided the ink jet according to the second aspect, wherein the ink jet main body is provided with a braking means for limiting a pressing amount of the ink penetrating member pressing portion against the ink penetrating member.

  According to a fourth aspect of the present invention, there is provided a ink brush body in which a ink penetrating member is accommodated in the ink brush main body in which a spool is incorporated, and thread insertion portions on both sides of the ink chamber in the yarn moving direction are the ink brushes. The ink infusion penetrating member is protruded toward the chamber, and is separated from the thread insertion portion.

  According to the ink brush of the first aspect of the invention, by pushing the pressing member, the portion of the pressing member that presses only the yarn displaces the yarn in the slit toward the depth direction of the slit. For this reason, even if the amount of the ink infiltrated and retained in the ink penetrating member is reduced to some extent, the ink ink can be sufficiently adhered to the thread to draw a clear ink line.

  According to the ink brush of the second aspect of the invention, by pushing the pressing member, the ink penetrating member pressing portion of the pressing member presses the ink penetrating member, and at the same time, the thread is formed on the ink penetrating member. Since the yarn is displaced in the depth direction in the slit, in addition to the effect of the first aspect, the ink can be sufficiently adhered to the yarn in the slit in which the ink in the ink penetrating member is oozed out by pressing.

  According to the ink brush according to the invention of claim 3, since the pressing amount of the ink penetrating member pressing portion with respect to the ink penetrating member is limited, in addition to the effect according to claim 2, the ink infusion due to excessive pressing of the ink penetrating member pressing portion Leakage can be prevented as much as possible.

  According to the ink brush according to the invention of claim 4, since the thread insertion portion protrudes toward the ink chamber, the relative expansion space around the ink chamber becomes the ink reservoir, and the ink penetrating member in the ink chamber is the thread. Since it is separated from the insertion part, leakage of the ink from the thread insertion part can be prevented as much as possible.

One end of the direction is exposed from the inner periphery of the bobbin cover 12 to the outside. These members are formed of a synthetic resin material, and the bobbin 2 can be taken out from the bobbin winding chamber 1A by removing the bobbin cover 12 from the bobbin storage portion 11A of the case 11.

  As shown in FIG. 5, a hooking claw 132 is formed on the inner side surface of the swinging end portion (end portion opposite to the hinge 131) 13 a of the ink chamber cover 13. The engaging claws 132 are snappedly engaged with engaging recesses 11b formed on the outer surface of the ink chamber forming portion 11B in the case 11 to fix the ink chamber cover 13 in a closed state.

  A packing 133 made of a rubber-like elastic material is provided on the inner surface of the ink chamber cover 13, and can be in close contact with the upper surface of the ink chamber forming portion 11 </ b> B in the case 11. The ink chamber 1B defined by the ink chamber forming portion 11B and the ink chamber cover 13 is made of sponge, absorbent cotton, felt, or the like, and preferably ink ink made of cellulose fibers excellent in penetrating and retaining action of ink. The penetrating member 4 is detachably accommodated.

  A thread insertion part 14 having a threading groove 14a is formed between the spool chamber 1A and the ink chamber 1B, and a thread insertion part 15 having a threading groove 15a is also formed between the ink chamber 1B and the thread outlet part 11C. Is provided. The thread insertion portions 14 and 15 facing each other are formed so as to protrude into the ink chamber 1B. In other words, the ink chamber 1B is formed on both sides of the thread insertion portions 14 and 15 as indicated by broken lines in FIG. The ink reservoir 16 extends toward both ends of the ink chamber forming portion 11B at (four locations).

  The ink penetrating member 4 is formed with a slit 4a having an appropriate depth from the upper surface, and the planar shape is substantially H-shaped as shown in FIG. 6, that is, a pair of recesses 4b are formed at both ends of the slit 4a. The both sides (four places) are the relative convex portions 4c. The ink infiltrating member 4 is positioned by loosely fitting the concave portions 4b on both sides with the guide protrusions 17 protruding from the bottom of the ink chamber forming portion 11B in the state of being accommodated in the ink chamber 1B. The concave portion 4b is spaced apart from the thread insertion portions 14, 15, and each convex portion 4c is filled in a state of being fitted into each ink reservoir portion 16 of the ink chamber 1B.

  A circular hole is formed in the ink chamber cover 13 in the ink fountain body 1, and a push button 134 made of a rubber material is closely fitted in the circular hole, and an inner surface of the push button 134 is made of a synthetic resin material. A pressing member 135 is attached. The pressing member 135 includes a pressing plate 135a extending in a direction corresponding to the moving path of the thread 3 in the ink chamber 1B, and a pair of pressing protrusions 135b protruding from both ends of the pressing plate 135a. Each pressing projection 135b is formed with a groove 135c at a position corresponding to the movement path of the yarn 3. The pressing plate 135a corresponds to the ink penetrating member pressing portion described in claim 2, and the pressing protrusion 135b corresponds to the “part that presses only the yarn” described in claim 1.

  When the ink chamber cover 13 is closed, the pressing member 135 is pushed down in the ink chamber 1B by pressing the push button 134 with a finger so as to be depressed, and the pressing plate 135a is moved to the ink penetrating member as shown in FIG. The upper surface of the portion where the slit 4 a is formed (hereinafter referred to as the intermediate portion 4 d) between the four recesses 4 b is pressed and compressed, and the pair of pressing protrusions 135 b enters the pair of recesses 4 b of the ink penetrating member 4. The thread 3 can be pushed toward both sides of the slit 4a in the depth direction of the slit 4a. Further, if the pressing with the finger is released, the pressing member 135 is returned by the restoring force of the push button 134.

  A guide protrusion 17 that protrudes from the bottom of the ink chamber forming portion 11B and fits into the recess 4b of the ink penetrating member 4 faces the pressing protrusion 135b of the pressing member 135 and is pressed by pressing the push button 134. When the member 135 is pushed down, it also serves as a braking means for limiting the amount of compression of the ink penetrating member 4 by the pressing plate 135a by contacting the pressing protrusion 135b.

  Note that the thread bottoms of the threading grooves 14a and 15a formed in the thread insertion portions 14 and 15 on both sides of the ink chamber 1B do not interfere strongly with the thread 3 pushed down by the pressing protrusion 135b of the pressing member 135. Furthermore, it is formed in an inclined shape that is deeper than the position where the thread 3 is pressed down and deeper on the ink chamber 1B side. Further, the slit 4 a of the ink penetrating member 4 is formed deeper than the maximum pressing position of the yarn 3 by the pressing member 135.

  The yarn lead-out portion 11C in the case 11 is formed so as to surround the funnel-shaped yarn lead-out hole 1C continuous from the threading groove 15a of the yarn insertion portion 15, and the edge of the yarn lead-out portion 11C is the yarn 3 drawn out from the yarn lead-out hole 1C. An annular thread retainer 18 for pressing the thread against the mating member. As shown in FIGS. 4 and 5, the yarn outlet hole 1C is formed by being shared by the fitting portion 13b between the yarn outlet portion 11C and the yarn outlet portion 11C of the ink chamber cover 13. ing.

  The yarn 3 wound around the bobbin main body 21 of the bobbin 2 passes through the slit 4a of the ink infiltrating member 4 in the ink chamber 1B from the threading groove 14a formed in the yarn insertion portion 14 between the bobbin chamber 1A and the ink chamber 1B. In addition, the yarn is guided out of the case 11 from the yarn outlet hole 1C through the thread passage groove 15a formed in the yarn insertion portion 15 between the ink chamber 1B and the yarn outlet portion 11C.

  Reference numeral 5 is a spring charger. The spring charger 5 is concentrically disposed on the inner periphery of the bobbin 2 so as to be concentrically and relatively rotatable, and on the outside of the bottom wall of the bobbin storage portion 11A in the case 11. A disc-shaped charge handle 52, a clutch member 53 fixed to the central axis of the charge handle 52 inserted through the shaft hole formed in the bottom wall, and a lever 54 provided on the charge handle 52. The urging force of the spiral spring 22 incorporated in the bobbin 2 is arbitrarily adjusted.

  As shown in FIG. 4, a chalcone 6 is connected to the tip of the yarn 3 led out of the case 1. The calco 6 basically includes a hollow handle 61 made of a synthetic resin and a metal fastening needle 62 attached to the handle 61 integrally or detachably. In order to enhance safety, the chalcone 6 normally has a fastening needle 62 housed in the handle 61 by a spring (not shown). In use, the pressing piece 63 is pushed to resist the urging force of the spring. Thus, it can be protruded from the handle 61. The tip 61a of the handle 61 is formed in a shape that can be held in the fitted state in the yarn outlet hole 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 13 and injecting the ink into the ink chamber 1B.

  In the inking (drawing) operation by the ink brush, first, the calco 6 is fixed by inserting the fixing needle 62 into one of the starting points of the ink marking on the surface of the other material (not shown), and then fixing the ink brush main body 1. When moving toward the other starting point of the ink brush, the thread 3 is pulled out by the moving distance of the ink brush main body 1 while the spool 2 is rotated. This thread 3 is drawn out through the slit 4a of the ink penetrating member 4 in the ink chamber 1B, and the ink ink adheres by sliding on the ink penetrating member 4. Further, the spiral spring 22 incorporated in the bobbin 2 is wound around the spring core 51 as the bobbin main body 21 rotates, and stored.

  When the ink penetrating member 4 is impregnated with a sufficient amount of ink, since the ink is held to the upper part of the ink penetrating member 4 by capillary action, the thread 3 is pressed by the pressing member 135 as shown in FIG. Even when the ink is not pushed down, the ink 3 necessary and sufficient for transferring the black line can be adhered to the thread 3 passing through the slit 4a.

  After moving the ink brush body 1 to the other starting point of the ink brush body, the thread 3 is pressed against the surface of the mating material with the thread presser 18 at the tip of the ink brush body 1, so that the thread 3 is properly placed between the calco 6 Tension with appropriate tension. If the thread 3 is hit with a finger toward the surface of the counterpart material, a linear ink line can be transferred by the ink sticking to the thread 3.

  After the completion of the inking operation, when the ink jet main body 1 is moved toward the calco 6 that is fixed to the counterpart material, the bobbin 2 is wound in the winding direction due to the loosening operation of the spiral spring 22 accumulated in the process of drawing out the yarn 3. Therefore, the yarn 3 is automatically wound around the bobbin main body 21. Finally, when the chalcone 6 is pulled out of the mating member, the yarn 3 is further wound up and the chalcone 6 is locked in the yarn outlet hole 1C in a semi-contained state.

  If the amount of the ink impregnated in the ink penetrating member 4 in the ink chamber 1B is reduced to some extent due to the repetition of the ink-making operation, etc., the amount of ink retained on the upper portion of the ink penetrating member 4 decreases, and the ink penetrating member 4 (ink ink) Since the ink ink is unevenly distributed in the lower part of the chamber 1B), the ink ink does not easily adhere to the thread 3 passing through the slit 4a.

  Therefore, in such a case, as shown in FIG. 7, when the push button 134 is pressed and depressed, the pressing member 135 is pushed downward via the push button 134, and the pressing member 135 The plate 135a presses and compresses the upper surface of the intermediate portion 4d of the ink penetrating member 4, and a pair of pressing projections 135b located in the pair of recesses 4b of the ink penetrating member 4 causes the thread 3 in the slit 4a to be slit. Push down on both sides of 4a in the depth direction. At this time, the thread 3 passes through the grooves 135c and 135c in the pressing protrusions 135b and 135b.

  For this reason, the ink which is unevenly distributed and impregnated in the lower part of the ink penetrating member 4 oozes upward due to the compression of the ink penetrating member 4, and the thread 3 is pushed down. Can do. In addition, the pressing member 135 compresses the intermediate portion 4d of the ink penetrating member 4 and pushes the thread 3 to an appropriate depth in the slit 4a as described above, and the thread 3 is forced to the ink penetrating member 4. Therefore, it is possible to prevent the ink infiltration member 4 from being worn.

  At this time, the thread 3 is slanted between the pressing protrusions 135b and 135b of the pressing member 135 and the threading grooves 14a and 15a of the thread insertion portions 14 and 15, but the threading groove 14a. , 15a is deeper than the position of the thread 3 at this time and is inclined so that the ink chamber 1B side is deeper, so that it is possible to prevent the thread 3 from being strongly hit and worn out as much as possible.

  In addition, when a large amount of ink is impregnated in the ink penetrating member 4 in the ink chamber 1B, if the push button 134 is pressed with fingers, the ink leakage from the thread outlet hole 1C occurs in the conventional ink brush. However, according to the ink brush of the present invention, such a problem can be effectively prevented.

  That is, when the intermediate portion 4d of the ink penetrating member 4 is compressed by the pressing plate 135a of the pressing member 135, a portion of the ink impregnated and held therein is uncompressed 4 of the ink penetrating member 4 by capillary action. It moves to the convex part 4c of the location, in other words, it moves to the 4 ink reservoirs 16 in the ink chamber 1B. Further, the amount of compression of the intermediate portion 4 d of the ink penetrating member 4 by the pressing plate 135 a is limited by the pressing protrusion 135 b coming into contact with the guide protrusion 17. For this reason, the exudation of the ink from the intermediate part 4d to the concave parts 4b, 4b facing the thread insertion parts 14, 15 is suppressed.

  Moreover, since the recesses 4b and 4b of the ink penetrating member 4 are separated from the thread insertion portions 14 and 15, even if the ink oozes out from both ends into the recesses 4b and 4b due to the compression of the intermediate portion 4d, the ink is inserted into the thread. It cannot move directly to the threading grooves 14a and 15a of the parts 14 and 15. For this reason, ink leakage is effectively suppressed.

  If the ink ink does not sufficiently adhere to the thread 3 even when the push button 134 is pressed, the ink chamber cover 13 may be opened as described above to replenish the ink chamber 1B with the ink ink.

  The pressing member 135 pushes down the thread 3 in the slit 4a toward the depth direction of the slit 4a, so that the thread 3 is displaced to the lower part of the ink penetrating member 4 in which the ink is unevenly distributed and impregnated. Even if the pressure plate 135a that presses the ink penetrating member 4 is not provided, it is possible to improve the ink sticking. Further, the shape of the pressing member 135 is not limited to the shape in which the pressing protrusion 135b is provided, and it is sufficient that there is a portion that can press only the thread 3, and various shapes such as an arc shape are conceivable. Further, the portion that presses only the thread, such as the pressing protrusion 135b, may be only one (one side) or may be three or more, and the shape is not limited to a concave shape, and various shapes can be considered. 135c is not necessarily formed.

  Moreover, the shape of the ink penetrating member 4 is not limited to the shape as shown in FIG. 6, and the planar shape may be a rectangle or a circle as long as it is separated from the thread insertion portions 14 and 15, and various shapes are conceivable. Further, a plurality of ink infiltration penetrating members 4 may be accommodated in the ink chamber 1B.
