Description

  The present invention relates to an ink brush that stretches a thread to which a colored liquid such as ink is attached in a woodwork or a construction work, and transfers a line using the thread.

  Traditionally, ink brushes used to draw ink lines in woodwork and construction work have been basically provided with a spool and a ink penetrating member in the case, and the yarn wound around the spool swallows the ink in the case. While being in contact with the inked ink penetrating member, the yarn is fed out from the yarn feeding port formed at one end of the case, and a calco for fixing the yarn to the starting point of the ink at the tip of the yarn. The structure is connected.

  In this type of sumi-fied work, first, when the case is moved after the calco is fixed to the starting point of the other material, the thread drawn from the spool is connected to the ink penetrating member. Since the ink sticks due to contact, the fingers should be repelled toward the ink-printed surface of the mating material with appropriate tension applied between the end on the calco side and the end on the case side. Thus, a straight black line can be transferred to the counterpart material.

  In general, this type of ink brush is generally used in a case in which a pincushion storage portion of a case in which a pincushion is rotatably stored is opened and closed by an annular lid at one outer periphery of a rotation axis of the pincushion, and a case in which a ink penetrating member is stored The penetrating member storage portion is opened and closed by a cover that swings via a hinge that is substantially parallel to the thread passing through the ink penetrating member storage portion on the same side as the cover that opens and closes the pincushion storage portion on one side in the axial direction of the pincushion. In order to press the yarn drawn out from the yarn feeding port against one starting point of the black ink on the counterpart material, a yarn presser portion formed at the end of the case opposite to the spool portion (on the yarn feeding port side) Of the outer periphery of the feeding opening, it is provided on the same side as the cover for opening and closing the bobbin storage part and the cover for opening and closing the ink penetrating member storage part (see, for example, Patent Document 1 below).

  Further, it is also known that the thread holding portion is provided on the outer periphery of the yarn feeding port on a side that is approximately 90 degrees different from the cover that opens and closes the bobbin storage portion and the cover that opens and closes the ink penetrating member storage portion (for example, See Patent Document 2 below).

Japanese Patent No. 2727285 JP 2009-95927 A

  In the case of the above-described conventional ink brushes, the case's pincushion storage part is opened and closed on one side in the axial direction of the pincushion. When the bobbin is set again in the bobbin storage part after it is taken out, the bobbin winder is usually turned up with the opening of the bobbin storage part from which the cover is removed facing upward, and the axis of rotation is directed vertically. Insert into the storage unit from above and set. For this reason, a part of the yarn wound around the outermost part of the yarn wound around the bobbin is scattered in the process of putting the bobbin into the bobbin storage unit, and between the side surface of the bobbin winding and the side surface of the bobbin storage unit There is a problem that it is easy to fall off and be bitten. Therefore, a knack is required for the operation of setting the bobbin into the bobbin storage part while preventing the thread from falling off, which is troublesome.

  Also, when removing the bobbin from the bobbin storage part to the outside of the case, the cover that opens and closes the bobbin storage part is completely removed from the case, so before setting the bobbin into the bobbin storage part again, There is a risk of losing the cover.

  The present invention has been made in view of the above points, and its technical problem is that when a bobbin is set in the bobbin storage part of the case, a part of the yarn wound on the bobbin is scattered. It is an object of the present invention to provide an easy-to-use ink brush that does not easily fall between the side surface of the bobbin and the side surface of the bobbin storage part.

  As a means for effectively solving the above technical problem, the ink cartridge according to the invention of claim 1 is wound around a case, a bobbin housed in a bobbin housing portion formed in the case, and the bobbin winder. And a yarn that is pulled out through a yarn feed opening provided at one end of the case and attached with a fastening device at the tip, and is formed in the case between the bobbin winding portion and the yarn payout port. In the ink fountain, which is stored in the ink chamber and is provided with an ink stick adhering means for adhering the ink to the yarn, the pincushion storing part engages the pincushion rotatably on one side in the axial direction, and the pincushion A bobbin cover capable of opening and closing substantially half the circumference of the storage unit is provided, and the state of engagement of the bobbin with the bearing unit is maintained by the bobbin cover.

  In addition, the “ink ink” here is not limited to the original ink ink but refers to all colored liquids that can be used for marking.

  The ink brush having the structure of claim 1 is arranged such that the yarn wound around the bobbin is fed out of the case from the yarn feeding port while the ink is attached inside the case by the ink stick attaching means. A straight ink line is created by stretching between a fastening tool that has been fixed to the starting point of ink and a thread presser protrusion that is pressed to the other starting point of ink, and then flicking this thread toward the surface of the mating material with your fingers. Is to be transferred. Since the bobbin cover provided in the bobbin storage unit opens and closes approximately half the circumference of the bobbin storage unit, when setting the bobbin in the bobbin storage unit, the bobbin is inserted into the bobbin storage unit with the bobbin cover open. Since it is inserted in a direction crossing the shaft center and one side in the axial direction is engaged with the bearing portion, the yarn wound around the bobbin is scattered at that time and between the side surface of the bobbin winding and the side surface of the bobbin winding unit. It is difficult to drop off, and the axial displacement of the bobbin is restricted by closing the bobbin cover, and the engaged state with the bearing portion is maintained, and smooth rotation is compensated.

  According to a second aspect of the present invention, in the ink brush according to the first aspect of the present invention, the end of the pincushion cover opposite to the ink chamber portion in the pincushion storage portion via a hinge that is substantially parallel to the rotational axis of the pincushion. Are combined.

  According to the configuration of the second aspect, the bobbin cover opens and closes substantially half the circumference of the bobbin storage part via the hinge, and is not completely removed when the bobbin storage part is opened. Absent.

  According to a third aspect of the present invention, the ink brush according to the invention of the third aspect is arranged such that the ink chamber side cover for opening and closing the ink chamber portion and the thread feeding port is connected to the swinging end portion of the spool cover, The thread path from the spool through the ink chamber and the thread delivery port is opened by opening the spool cover and the ink chamber side cover that are connected to each other.

  According to the configuration of the third aspect, the thread path from the spool through the ink chamber and the thread feeding opening is opened by opening the thread winding cover and the ink chamber side cover which are connected to each other. In such a case, it is possible to easily perform a repair operation such as drawing out the yarn wound around the spool, passing it through the ink chamber portion and the yarn feeding port, and attaching a fastening tool to the tip of the yarn chamber.

  According to a fourth aspect of the present invention, in the configuration described in any one of the first to third aspects, the pincushion cover is opened on the inner peripheral edge of the side wall opposite to the bearing portion in the pincushion storage portion. An inclined surface is formed to allow the pincushion to be tilted when the pin is engaged with or released from the part.

  According to the configuration of the fourth aspect, for example, for the purpose of repairing the yarn, it is possible to easily take out the pincushion from the pincushion storage part to the outside of the case and then set the pincushion into the pincushion storage part again.

  According to the ink brush according to the present invention, when the bobbin is set in the bobbin storage part, a part of the thread wound on the bobbin is not easily dropped between the side surface of the bobbin and the side surface of the bobbin storage part, thereby improving workability. Can be improved.

  Hereinafter, preferred embodiments of the ink brush according to the present invention will be described in detail with reference to the drawings.

  In each figure, reference numeral 1 is a case formed of a synthetic resin material. The case 1 includes a case main body 11, a pincushion cover 12, and an ink chamber side cover 13. The case main body 11 includes a bobbin storage portion 11A having a substantially semicircular projected shape in the axial direction, a black chamber portion 11B in front thereof (right side in FIGS. 1 and 2, etc.), and a yarn feeding port 11D in front thereof. Have. As a whole, the case 1 has a portion composed of the ink chamber portion 11B of the case main body 11 and the ink chamber portion side cover 13 that opens and closes the case, and a portion composed of the bobbin storage portion 11A of the case main body 11 and the bobbin cover 12 that opens and closes the case. Since a finger-hanging recess 11C is formed between the bottom of the spool housing 11A and the bottom of the ink chamber 11B, the shape can be held with one hand as if holding a handgun grip. It has become.

  The bobbin cover 12 has a hinge 121 whose axial center is substantially parallel to the rotational axis of the bobbin 2 described later at the rear end (end opposite to the ink chamber portion 11B side) of the upper opening of the bobbin storage portion 11A in the case body 11. The projected shape in the axial direction is substantially semicircular, and defines a space for rotatably holding the bobbin 2 between the bobbin storage part 11A.

  As shown in FIGS. 4 and 5, the ink chamber side cover 13 can swing on the outer surface of the ink chamber portion 11 </ b> B of the case body 11 via a hinge 131 whose axis is substantially parallel to the direction in which the thread 3 is pulled out. The upper part of the ink chamber 11B and the thread delivery port 11D is opened and closed. The rear end portion 13a of the ink chamber side cover 13 is connected to the swing end portion (end portion opposite to the hinge 121) 12a of the spool cover 12, and the swing end portion 12a of the spool cover 12 is connected to the swing end portion 12a. The pincushion storage portion 11A is locked in a closed state by fitting with the rear end 13a of the ink chamber side cover 13, that is, the pincushion cover 12 is also opened by opening the ink chamber side cover 13. Be able to.

  As shown in FIGS. 2 and 3, the bobbin 2 is attached between a bobbin main body 21 that winds the bobbin 3 around its outer periphery and a spring core 23 that is concentrically and relatively rotatably disposed on its inner periphery. And a spiral spring 22 that urges the bobbin main body 21 in the winding and rotating direction of the yarn 3, and is prevented from being removed from the bobbin storage portion 11A of the case main body 11 by the bobbin cover 12, and held in a rotatable state. ing.

  As shown in FIG. 1, one end 21a in the axial direction of the bobbin main body 21 has an inner periphery that extends outward from a circular opening 1a formed by a bobbin storage part 11A of the case main body 11 and a bobbin cover 12 that is closed. A large number of friction members 24 made of rubber-like elastic material (rubber material or synthetic resin material having rubber-like elasticity) are attached to the exposed surface at equal intervals in the circumferential direction. On the other hand, the flange portion 23a of the spring core 23 positioned at the other axial end (inner end) of the bobbin main body 21 is formed on an annular bearing portion 111 formed on the inner surface of the bobbin storage portion 11A as shown in FIG. It is rotatably supported and is detachably engaged with a spring charger 5 described later.

  As shown in FIG. 1, a hooked nail 132 and a finger hook 133 are formed at the swing end of the ink chamber side cover 13 (the end opposite to the hinge 131). The hooking claws 132 are engaged with the hooking claws 112 formed on the outer surface of the ink chamber portion 11B of the case body 11 to fix the ink chamber portion side cover 13 in the closed state.

  As shown in FIGS. 2, 4, and 5, a packing 134 made of a rubber-like elastic material is provided on the inner surface of the ink chamber side cover 13, and closely contacts the upper opening edge of the ink chamber portion 11 </ b> B in the case body 11. It is possible. In the ink chamber 11B, an ink penetrating member 4 made of cellulose, made of sponge, absorbent cotton, felt, or the like, and preferably made of cellulose fibers excellent in ink penetrating and retaining action, is detachably housed. The ink infiltration penetrating member 4 corresponds to the ink ink adhering means described in claim 1, and as shown in FIG. 5, a slit 4 a for passing the thread 3 is formed therein.

  A thread insertion part 11E is formed between the bobbin storage part 11A and the ink chamber part 11B in the case main body 11, and a thread insertion part 11F is formed between the ink chamber part 11B and the thread feeding port 11D. A thread feeding port 11D having a funnel shape projecting into the ink chamber portion 11B and a thread insertion portion 11F located at the protruding end are formed between the case body 11 and the ink chamber side cover 13 fitted thereto. The yarn 3 wound around the bobbin main body 21 of the bobbin 2 passes through the slit 4a and the thread insertion part 11F of the ink penetrating member 4 in the ink chamber part 11B from the thread insertion part 11E, and the thread feeding port 11D. To the outside of the case 1.

  As shown in FIG. 2, a metal guide pin 122 that is substantially parallel to the rotational axis of the bobbin 2 is attached to the swinging end (end opposite to the hinge 121) 12 a of the bobbin cover 12. The guide pin 122 defines the path of the thread 3 between the spool 2 and the ink penetrating member 4. Specifically, in a state in which the bobbin cover 12 is closed, the yarn 3 wound around the bobbin main body 21 passes through a position in sliding contact with the guide pin 122 in the process from the inner peripheral side of the bobbin cover 12 to the ink penetrating member 4. Thus, the thread 3 is guided so as to pass through the slit 4 a of the ink penetrating member 4.

  In the illustrated example, the thread 3 wound clockwise around the spool 2 in the cross section shown in FIG. 2 extends from the upper half of the spool 2 through the lower side of the guide pin 122 and into the ink penetrating member 4. Since the direction of the yarn 3 is not bent at a large angle with the guide pin 122 as a boundary, a large load is not applied in the process of drawing or winding the yarn 3.

  A circular hole is formed in the ink chamber side cover 13, and a push button 135 continuous with the packing 134 is closely fitted in the circular hole, and a pressing member 136 is formed on the inner surface of the push button 135. The pressure member 136 is pushed down by pressing the push button 135 with a finger from the outside, and the ink penetrating member 4 is compressed and deformed.

  The end portion of the ink chamber side cover 13 opposite to the bobbin winding portion 11A, that is, the portion located on the outer periphery of the yarn feeding port 11D is inclined outward with respect to the direction parallel to the central axis of the yarn feeding port 11D. A thread presser protrusion 137 extending in a united manner is formed integrally, and its tip 137a is located outside the extended surface of the outer surface of the case 1 (ink chamber side cover 13). The thread presser protrusion 137 has a tapered shape whose width decreases toward the tip 137a, and a plurality of thread hooking grooves 137b are formed on the tip 137a.

  Further, the bobbin 2 side of the case 1 (part consisting of the bobbin storage portion 11A and the bobbin cover 12) was gripped on the surface opposite to the yarn delivery port 11D of the yarn presser protrusion 137, that is, the surface adjacent to the push button 135. A finger contact recess 137c is formed that can be applied to the tip of a hand finger (for example, an index finger).

  As shown in FIG. 3, a spring charger 5 that can be engaged with the spring core 23 of the bobbin 2 is attached to one side of the bobbin storage portion 11 </ b> A in the case body 11. The spring charger 5 has a known structure including a one-way clutch mechanism and a release mechanism thereof, and arbitrarily adjusts the urging force of the spiral spring 22 incorporated in the bobbin 2.

  Further, the inner peripheral surface of the side wall 113 opposite to the bearing portion 111 in the bobbin storage portion 11A of the case body 11, that is, the inner peripheral surface of the bobbin storage portion 11A constituting the circular opening 1a of the case 1 is The inclined surface 113a is inclined so as to become deeper inward.

  As shown in FIG. 2, a chalcone 6 is connected to the tip of the yarn 3 led out of the case 1. The calco 6 corresponds to the fastening device described in claim 1, and includes a hollow handle 61 made of synthetic resin and a metal fastening needle 62. The needle 62 is housed in the handle 61 by a spring (not shown), and when used, the handle 61 is pinched with fingers and the pressing piece 63 is moved to a position indicated by a one-dot chain line against the urging force of the spring. By pushing, it can project from the handle 61. In addition, the tip 61a of the handle 61 is formed in a shape that can be held in a fitted state in the funnel-shaped yarn feeding port 11D in the case 1.

  When using the ink brush of the embodiment configured as described above, the ink ink penetrating member 4 in the ink chamber portion 11B is sufficiently impregnated with ink ink in advance. The ink infusion penetrating member 4 can be impregnated with the ink by opening the ink chamber side cover 13 and injecting the ink into the ink chamber 11B.

  In the inking (drawing) operation, for example, first, the calco 6 is fixed by inserting the fixing needle 62 into one of the starting points of inking on the surface of the counterpart material, and then fixing the case 1 to the other of the inking. When moved toward the starting point, the yarn 3 is pulled out by the moving distance of the case 1 with the rotation of the bobbin 2. The thread 3 adheres to the ink penetrating member 4 in a process of passing through the slit 4a of the ink penetrating member 4 in the ink chamber portion 11B, and the spiral spring 22 incorporated in the spool 2 is connected to the spool body. Accumulated with the rotation of 21. As shown in FIG. 6, the case 1 can be gripped with one hand so as to grip the handgun, and can be easily gripped by the presence of the finger-holding recess 11 </ b> C. It ’s easy to use.

  When the case 1 is moved to the other starting point of the inking, as shown in FIG. 7, the thread 3 is hung on the thread hooking groove 137b of the thread presser protrusion 137 and held on the surface of the mating member W to thereby stop the thread. 3 is stretched between the calco 6 and an 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.

  Here, since the thread presser protrusion 137 is formed in a tapered shape with a width decreasing toward the tip 137a side, the inking start point on the side opposite to the fixing portion by the calco 6 is narrow, for example, at the back of the corner of the entrance. Even in the place, the thread presser protrusion 137 can hold the thread 3. Moreover, the thread presser protrusion 137 extends while being inclined outward with respect to the direction parallel to the center axis of the thread delivery port 11D, and its tip 137a is outside the extended surface of the outer surface of the case 1 (ink chamber side cover 13). Therefore, it is difficult to see the position where the thread 3 is stopped. Therefore, it is possible to perform the inking by accurately pressing the yarn 3 even in a narrow place such as a corner.

  Since the thread presser protrusion 137 is formed at the end of the ink chamber side cover 13 constituting the case 1, the thread presser protrusion 137 is reduced in size as compared with a conventional thread presser member made of metal. It is possible to reduce the number of parts and the cost.

  Further, when the yarn 3 is held against the mating member by the yarn holding protrusion 137, as shown in FIG. 7, the hand holding the bobbin 2 side of the case 1 (portion comprising the bobbin storage portion 11A and the bobbin cover 12). By applying the tip of the finger (for example, the index finger) to the finger contact recess 137c formed on the thread presser protrusion 137, it is easy to press, and thus it is easy to use.

  After completion of the inking operation, if the case 1 is moved toward the calco 6 fixed to the counterpart material, the bobbin 2 is moved in the winding direction by the loosening action of the spiral spring 22 accumulated in the process of pulling out the yarn 3. Because of the rotation, the yarn 3 is automatically wound around the bobbin main body 21. Finally, when the chalcone 6 is pulled out from the mating member, the yarn 3 is further wound up, and the tip 61a of the handle 61 of the chalcone 6 is locked in a fitted state at the yarn feeding port 11D.

  In the state where the case 1 is gripped with a hand as shown in FIG. 6, a part of the palm (or a part of the finger) can be brought into contact with a number of friction members 24 shown in FIG. Depending on the friction, the automatic winding speed of the yarn 3 due to the urging force of the spiral spring 22 can be easily controlled, or the gripping action of the friction member 24 can be easily held by hand.

  Further, when the yarn 3 is broken due to repeated use, the yarn 3 is all wound around the spool body 21 of the spool 2 by the urging force of the spiral spring 22, so that it is wound up for reuse. The thread 3 needs to be pulled out of the case 1 through the thread insertion part 11E, the slit 4a of the ink penetrating member 4 and the thread insertion part 11F, and connected to the calco 6 again. In such a case, as shown in FIG. 4, when the ink chamber side cover 13 is opened and the pincushion cover 12 unlocked thereby is opened, the upper half circumference of the outer periphery of the pincushion 2 is opened. As shown in FIG. 5, the entire threading path from the bobbin 2 to the yarn unwinding port 11D is opened. Further, at this time, the pincushion cover 12 and the ink chamber side cover 13 are attached to the case body 11 via the hinges 121 and 131, so that they are not lost.

  Here, since the inner peripheral surface of the side wall 113 opposite to the bearing portion 111 in the bobbin storage portion 11A of the case body 11 is an inclined surface 113a, when the bobbin cover 12 is opened, as shown in FIG. The pincushion 2 can be tilted to the opposite side of the spring charger 5. And if it tilts in this way, the engagement between the spring charger 5 and the bearing portion 111 and the flange portion 23a of the spring core 23 of the bobbin 2 is released, and thereafter, from the opened upper half circumference of the bobbin storage portion 11A. The thread winding 2 can be taken out in the direction (upward) intersecting the axis thereof, the thread 3 can be pulled out, and the work of re-binding to the calco 6 can be performed.

  In order to set the bobbin 2 in the bobbin storage part 11A after the thread 3 is tied to the calco 6, the bobbin cover 12 is put into the bobbin storage part 11A with the cover 12 opened and the bobbin 2 is inserted in a direction intersecting the axis. From the inclined state as shown in FIG. 8, one axial side (the flange portion 23 a of the spring core 23) is engaged with the bearing portion 111 and the spring charger 5. In the course of this work, the axis O of the bobbin 2 is substantially horizontal although it is temporarily inclined, so that the thread 3 wound around the bobbin 2 is scattered from the outer periphery and the side surface of the bobbin 2 and the bobbin. It is difficult to drop off between the storage portion 11A and the side surface (bearing portion 111), so that the operation of setting the bobbin 2 in the bobbin storage portion 11A is facilitated.

  Further, as described above, since the entire threading path from the bobbin 2 to the yarn unwinding port 11D is open, as shown in FIG. It is also possible to easily perform the setting operation so as to lead out from the yarn feeding port 11D to the outside of the case 1 through the slit 4a of the ink penetrating member 4 in the chamber portion 11B and the thread insertion portion 11F.

  When the setting operation of the bobbin 2 and the bobbin 3 is finished, the bobbin cover 12 and the ink chamber side cover 13 are closed. At this time, the ink chamber portion side cover 13 is fixed in a closed state by snapping the hooking claws 132 of the swinging end portions thereof onto the hooking claws 112 formed on the outer surface of the case body 11. The pincushion cover 12 is fixed in a closed state by the ink chamber side cover 13. Then, the axial displacement of the bobbin 2 is restricted by the closure of the bobbin cover 12 so that the engagement state between the bearing 111 and the spring charger 5 is maintained, smooth rotation is compensated, and the swinging end of the bobbin cover 12 is maintained. The thread 3 is guided into the slit 4a of the ink penetrating member 4 by the guide pin 122 attached to 12a.

  In the above-described embodiment, the ink chamber side cover 13 is provided so as to be swingable through the hinge 131 that is substantially parallel to the direction in which the thread 3 is pulled out. Other forms such as one that slides in a direction perpendicular to the moving direction of the yarn and one that can rotate 90 degrees are also conceivable.
