Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to an ink penetrating member that is housed in an ink fountain used for ink making work in woodworking or construction, and adheres ink ink to ink printing thread.
[0002]
[Prior art]
For example, as shown in FIG. 5, the ink brush used by a construction worker or the like is basically an outer periphery inking thread 104 of a reel 103 urged in a thread winding direction by a spiral spring (not shown) in a thread winding case 101. The ink strike thread 104 passes through the ink penetrating member 105 accommodated in the main body case 102 and is fed out from the thread feeding port 102a of the main body case 102 to the outside. A sword 106 for attaching to the surface A to be inked, such as wood, is attached to the tip of the inked yarn 104 fed out from the yarn feeding port 102a.
[0003]
The inking operation using the ink brush is performed by first fixing the main body case 102 to a predetermined position after the karuko 106 is fixed at the starting point of the inking by sticking the piercing needle 106a into the inking target surface A. By moving it, the ink strike yarn 104 wound around the reel 103 in the spool case 101 is fed out by the moving distance of the main body case 102, and in the drawing process, the ink sump held by the ink penetrating member 105 in the main body case 102. A black line is transferred by sticking the black line 104 between the karuko 106 and the main body case 102 toward the surface A to be printed with a finger. It is performed by the procedure of Further, after completion of the inking operation, if the ink 106 is pulled out from the inking target surface A by forcibly pulling the inking thread 104 or the like, the spiral spring accumulated when the inking thread 104 is fed out. The urging force of the reel 103 causes the reel 103 to rotate in the winding direction, so that the ink strike thread 104 is automatically wound around the reel 103 until the karuko 106 is locked to the thread feeding port 102a of the main body case 102. Taken.
[0004]
The ink penetrating member 105 is made of, for example, a sponge or the like, and is formed with a single slit 105 a corresponding to the movement path of the ink strike thread 104 in the main body case 102. The inner end of the yarn guide tube 102b formed at the end of the main body case 102 on the yarn winding case 101 side and the inner end of the yarn feeding port 102a on the opposite side are sandwiched between both ends of the slit 105a, The ink hitting thread 104 passes through the slit 105a of the ink penetrating member 105 between the yarn guide tube 102b and the yarn feeding port 102a.
[0005]
[Problems to be solved by the invention]
According to the conventional ink penetrating member 105, the slit 105a through which the ink hitting thread 104 passes is opened as shown in FIG. 6 due to the thread feeding port 102a and the thread guide tube 102b being sandwiched between both ends thereof. There is a problem that the ink printing thread 104 does not easily come into contact with the ink ink penetrating member 105, and the ink ink does not adhere sufficiently during the yarn feeding process. Such a problem can be easily solved by making the ink penetrating member 105 small so that the ink penetrating member 105 is not sandwiched between the yarn feeding port 102a and the yarn guide tube 102b. Will decrease.
[0006]
The present invention has been made under the circumstances as described above, and the technical problem thereof is to ensure that the ink is sufficiently attached to the ink thread fed through the ink penetrating member. It is in.
[0007]
[Means for Solving the Problems]
As a first means for effectively solving the above technical problem, the ink brush penetrating member of the present invention is a first slit corresponding to the movement path of the ink brush thread in the main body case of the ink brush, Second and third slits intersecting the vicinity of both ends of the first slit are formed, and a yarn guide tube and a yarn feeding port formed at both ends of the main body case toward the inside of the main body case, respectively, It is sandwiched between both ends of the first slit separated by the second and third slits.
[0008]
According to the present invention, the ink penetrating member is deformed so as to open when both ends of the first slit are sandwiched between the yarn guide tubes formed at both ends of the main body case and the inner ends of the yarn feeding ports. Since the transmission of the deformation force is blocked by the second slit and the third slit, the first slit is not opened between the second slit and the third slit. Therefore, the ink strike yarn moving between the yarn guide tube and the yarn delivery port reliably contacts the substantially closed inner surface of the first slit between the second slit and the third slit, and the ink is Adhere well. Needless to say, the ink penetrating member is able to retain the ink ink in a portion outside the second and third slits, so that a sufficient amount of ink ink can be retained.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a plan view showing a partially broken ink brush using the ink penetrating member for ink brush according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line II-II ′ of FIG. In the ink brushes shown in these drawings, reference numeral 10 is a main body case, 20 is a thread winding case, and 30 is a reel that is rotatably accommodated in the thread winding case 20. A cylindrical outer joint 11 protrudes from one end of the main body case 10, and a cylindrical inner joint that can be inserted into the inner periphery of the outer joint 11 at a part of the outer periphery of the bobbin case 20 in the circumferential direction. The main body case 10 and the bobbin case 20 are detachable from each other and inserted into the outer joint portion 11 by rotating the inner joint portion 21 in a predetermined direction. It is connected with the state which can be rotated around.
[0010]
In the main body case 10 is formed a black chamber 10S in which the sponge 12 which is the ink penetrating member of the present embodiment is accommodated. In order to replenish the sponge 12 with the ink, An opening 10a that can be opened and closed by the cover 13 is formed in the portion. A thread guide tube 14 projecting into the ink chamber 10S is provided on the inner periphery of the end of the main body case 10 on the side of the thread winding case 20, and the end opposite to the thread winding case 20 is directed toward the interior of the ink chamber 10S. A funnel-shaped yarn feeding port 15 is provided.
[0011]
The bobbin winding case 20 and the inner joint portion 21 integrated therewith are divided into two parts, that is, an upper half case member 20A and a lower half case member 20B. The upper half case member 20A and the lower half case member 20B engage the engaging protrusions 22 and 23 that protrude from the inner joint portion 21 at symmetrical positions in the circumferential direction of 180 °, respectively, and the inner portion divided vertically. The joint portion 21 is assembled into a shape as a bobbin case 20 by fitting an O-ring 24 made of rubber into a base portion having a large diameter and binding it.
[0012]
The reel 30 accommodated in the bobbin winding case 20 includes a reel body 31, a spring core 32 incorporated in a substantially concentric and relatively rotatable state on the inner periphery thereof, one end fixed to the reel body 31 and the other end. Is provided with a spiral spring 33 that is fixed to the spring core 32 and urges the reel body 31 in the winding direction of the ink strike thread 1. The ink drum 1 is wound around the outer periphery of the reel body 31, and the ink yarn 1 passes through the yarn guide tube 14 and the sponge 12 in the ink chamber 10S, and is led out of the main body case 10 from the yarn feed port 15. Has been. In addition, a sword 2 for sticking the ink-striking partner material 1 to the ink-striking partner 1 is attached to the feeding end of the ink-striking thread 1 led out of the main body case 10. This spar 2 can be engaged with the thread delivery port 15 in a semi-contained state as indicated by a two-dot chain line in FIG.
[0013]
The reel body 31 has a circular window formed on the inner peripheral portion of the upper half case member 20 </ b> A with a winding handle 34 formed on the inner peripheral portion on one side in the axial direction for winding the black ink thread 1 by manual rotation. A charge handle 35 is formed at the end of the spring core 32 facing away from the take-up handle 34 and is formed on the inner peripheral portion of the lower half case member 20B. Is exposed to the outside. The charge handle 35 is engaged with an annular ratchet member 36 disposed on the outer periphery of the charge handle 35, whereby the spring core 32 can rotate only in the direction in which the spiral spring 33 is stored with respect to the ratchet member 36. It is like that. Further, an abutting protrusion 36a is formed at one place in the circumferential direction of the ratchet member 36, and this abutting protrusion 36a is provided at an impacted position projecting at a 180 ° symmetrical position in the circumferential direction of the annular clutch member 37. It is adapted to be brought into contact with one of the mating protrusions 37a and 37b. The clutch member 37 is pressed in one direction by a coil spring 38. Therefore, normally, the abutting protrusion 36a of the ratchet member 36 is prevented from rotating by abutting with one of the abutting protrusions 37a of the clutch member 37. ing.
[0014]
Therefore, when the reel body 31 is rotated in the feeding direction of the ink strike thread 1, the charge handle 35 is engaged with the ratchet member 36 that is prevented from rotating around the clutch member 37, thereby causing the spring core 32 in the feeding direction. Therefore, the spiral spring 33 is wound around the spring core 32 and gradually accumulated. Further, when the charge handle 35 is rotated in the same direction as the yarn winding direction in a state in which the ink hammering yarn 1 is completely wound up until the karuko 2 is locked to the yarn feeding port 15, the reel body 31 is rotated. Since the rotation of the winding handle 15 and the rotation of the charge handle 35 in the opposite direction are prevented because the karuko 2 is locked to the yarn feeding port 15, the spiral spring 33 can be arbitrarily set. Can be stored.
[0015]
Normally, one of the collision protrusions 37a of the clutch member 37 that is abutting with the abutting protrusion 36a of the ratchet member 36 causes the clutch member 37 to protrude from a small hole on the lower surface of the lower half case member 20B. By manually operating 37c and displacing the coil spring 38 in the compression direction (right direction in FIG. 2), the ratchet member 36 is detached from the abutting protrusion 36a, and the ratchet member 36 is engaged with the charge handle 35 (spring core). 32) and the urging direction by the spiral spring 33, and when it rotates 180 °, it collides with the other abutting projection 37b of the clutch member 37 and stops. Next, when the clutch member 37 is returned to the normal position by the urging force of the coil spring 38, the other collision projection 37b is disengaged from the collision projection 36a, and the ratchet member 36 has the charge handle 35 (spring core 32). At the same time, it rotates again in the urging direction by the spiral spring 33, and when it rotates 180 °, it stops when the abutting projection 36a reengages with the one of the abutting projections 37a. That is, by repeatedly repeating the operation of the clutch member 37 through the clutch lever 37c, the spring core 32 rotates intermittently by 180 ° in a direction to reduce the urging force of the spiral spring 33. The biasing force of the spring 33 can be arbitrarily reduced or completely released.
[0016]
The sponge 12 that is the ink infiltration member of the present embodiment housed in the ink chamber 10S of the main body case 10 has a substantially rectangular parallelepiped shape as shown in a perspective view in FIG. A first slit 121 corresponding to the path of the black ink thread 1 in the chamber 10 </ b> S, and second and third slits 122 and 123 orthogonal to the vicinity of both ends of the first slit 121 are formed. Then, the yarn guide tube 14 at both ends of the main body case 10 and the inner end portions 14a, 15a of the yarn feeding port 15 are separated by the second and third slits 122, 123 as shown in the perspective view of FIG. The first slit 121 is sandwiched between both end portions 121a and 121b. The depths d ₂ and d ₃ (d ₂ = d ₃ ) of the second and third slits 122 and 123 are formed deeper than the depth d ₁ of the first slit 121.
[0017]
A thread presser lever 16 is rotatably attached to the cover 13 of the main body case 10 via a shaft 17. The lever 16 rotates around the shaft 17 as shown by a broken line in FIG. 2 by pushing the outer end portion 16a with a finger, and the inner end portion 16b passes through the inside of the ink chamber 10S. This is forcibly pressed against the sponge 12 that has penetrated. Note that reference numeral 13 a in FIG. 2 is a seal for preventing ink leakage provided on the cover 13.
[0018]
As in the conventional case, the ink brush is pierced by the karuko 2 at the starting point of the inking, and then moved to a predetermined position, so that the inking thread 1 is fed out by the moving distance of the inking, and in the process ink ink adheres. The inking operation is performed by flicking the inked thread 1 with a finger toward the inking target surface. After completion of the inking operation, if the karuko 2 is pulled out of the surface to be inked (not shown) by forcibly pulling the inked yarn 1 or the like, the spiral spring accumulated when the inked yarn 1 is fed out. The reel main body 31 is rotated in the yarn winding direction by the urging force of 33, so that the black ink thread 1 is placed on the reel main body 31 until the karuko 2 is locked to the yarn feeding port 15 of the main body case 10. It is automatically wound up.
[0019]
As shown in FIG. 4, the first slit 121 of the sponge 12 is deformed so that both ends 121a and 121b sandwiching the yarn guide tube 14 and the yarn feeding port 15 are wide open. Since the light is not transmitted to the portion between the second slit 122 and the third slit 123, the intermediate portion 121c in the first slit 121 is not opened. Accordingly, the ink strike yarn 1 that moves in the middle portion 121c of the first slit 121 from the yarn guide tube 14 toward the yarn delivery port 15 when the yarn is delivered is the substantially closed inner surface of the first slit 121. The ink which is infiltrated and held in the sponge 12 is sufficiently adhered. For this reason, a clear black line can be transferred to the surface to be marked. In addition, when the amount of ink held in the sponge 12 decreases and it becomes difficult for the ink to adhere to the ink printing thread 1, the ink ink is surely pressed by pressing the ink printing thread 1 and the sponge 12 with the lever 16. Can be attached.
[0020]
The depths of the first to third slits 121 to 123 may be equal to each other, and the depth is preferably 70% or more of the thickness of the sponge 12.
[0021]
In the above-described embodiment, the ink penetrating member has been described as the sponge 12, but the present invention can also be applied to those made of other porous materials or fiber materials such as urethane.
[0022]
【The invention's effect】
As described above, according to the ink penetrating member for ink brush of the present invention, since the slit through which the ink strike thread does not open, the ink strike thread reliably contacts the inner surface of the slit during the thread feeding process during the ink making operation. It is possible to draw a clear ink line by allowing the ink ink to adhere sufficiently.
