[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of an ink brush used for a sanitizing work in woodworking or construction.
[0002]
[Prior art]
For example, as shown in FIG. 5, a typical conventional example of a sump used by a construction worker or the like is basically a reel 103 urged in a thread winding direction by a spiral spring (not shown) in a thread winding case 101. The outer periphery inking thread 104 is wound, and the inking thread 104 passes through the ink infiltrating member 105 accommodated in the main body case 102 and is fed out from the thread outlet 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 take-up direction, whereby the ink strike thread 104 is automatically taken up on the reel 103 until the karuko 106 is locked in the thread feeding hole of the main body case 102. It is done.
[0004]
[Problems to be solved by the invention]
According to the conventional ink brush, for example, the karuko 106 is inadvertently removed from the surface A to be inked in the process of inking, or by pulling the inking thread 104 after the inking operation is completed. When the ink is drawn out from the ink-printing target surface A, the longer the drawing-out length of the ink-making thread 104 is, the more the reel 103 rotates in the yarn winding direction. Therefore, in such a case, as shown by the one-dot chain line in FIG. 5, the karuko 106 will fly with the piercing needle 106a facing the ink bud side. There was a risk of piercing them.
[0005]
The present invention has been made under the circumstances as described above, and a technical problem thereof is to prevent the danger caused by the flying of the ink strike yarn when it is wound around the reel. .
[0006]
[Means for Solving the Problems]
As a means for effectively solving the technical problem described above, the ink brush according to the present invention has a center of gravity of a rotating portion including a reel body and a mass body provided at a part of the outer circumference of the reel body in the circumferential direction. Eccentric. Therefore, when the reel main body is rotated in the yarn winding direction by the spiral spring accumulated when the ink strikes the yarn, the rotating portion including the reel main body whose center of gravity is biased by the mass body generates radial vibration (backlash). Accordingly, the rotation speed is increased, that is, a part of the rotational motion is converted into the radial motion, thereby suppressing an increase in rotational speed. For this reason, the danger that the ink hammering yarn is wound up relatively slowly and the leading edge karuko flies toward the ink brush side is effectively prevented.
[0007]
More preferably, in the present invention, the mass body for biasing the center of gravity of the reel body is pivotally supported at one end on the outer periphery of the reel body so that the reel body can swing in the radial direction. By swinging, it is possible to contact the inner peripheral surface of the bobbin winding case. In this configuration, more preferably, a sliding portion of the mass body that can come into contact with the inner peripheral surface of the bobbin winding case is formed to be unevenly distributed on one end side of the mass body. That is, according to this configuration, when the reel body rotates in the yarn winding direction, the reel body whose center of gravity is biased by the mass body is rotated with radial vibration as described above, thereby suppressing an increase in rotational speed. In addition, the free end of the mass body is swung to the outer peripheral side due to centrifugal force, so that one side surface is in contact with the inner peripheral surface of the bobbin case, and the frictional resistance generated thereby acts as a restraint force on the increase in rotational speed. To do. In addition, when the sliding portion of the mass body is formed to be unevenly distributed on one end side of the mass body, a large frictional resistance is generated by the action of the lever with one end of the mass body as a fulcrum, and rotation As the speed increases, the frictional resistance between the mass body and the inner peripheral surface of the thread winding case due to the centrifugal force becomes larger, so that an increase in the speed of the reel winding rotation of the reel body can be effectively suppressed.
[0008]

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.
[0009]
In the main body case 10, a black chamber 10 </ b> S filled with a sponge 12 as a ink penetrating member is formed. The black chamber 10 </ b> S is a normal case in the main body case 10 in order to refill the sponge 12 with ink. It can be opened and closed by a cover 13 detachably fitted to the upper portion. A thread insertion 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 spool case 20, and the end opposite to the spool case 20 is directed toward the interior of the ink chamber 10S. A funnel-shaped yarn feeding port 15 is provided.
[0010]
The reel 30 in the bobbin winding case 20 has a reel main body 31, and the ink strike thread 1 wound around the reel main body 31 contacts the sponge 12 soaked with ink through the thread insertion tube 14 and the ink chamber 10S. Then, it is led out of the main body case 10 from the yarn delivery port 15. Further, a thread presser lever 16 is rotatably attached to the cover 13 via a shaft 17. When the outer end portion 16a is pushed with a finger, the lever 16 pushes the shaft 17 as shown by a broken line in FIG. The ink drum 1 is rotated about the center and the ink end yarn 16 passing through the ink chamber 10S and the sponge 12 in which the ink ink penetrates are forcibly pressed to sufficiently adhere the ink ink to the ink strike yarn 1. Note that reference numeral 13 a in FIG. 2 is a seal for preventing ink leakage provided on the cover 13.
[0011]
A karuko 2 for sticking the ink-striking material 1 and fixing the ink-striking thread 1 is connected to the feeding end of the ink-striking thread 1 led out of the main body case 10 from the thread-feeding port 15. ing. The spar 2 is engaged with the thread delivery port 15 in a semi-contained state as indicated by a two-dot chain line in FIG.
[0012]
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 25 made of rubber into a base portion 24 having a large diameter and binding the same.
[0013]
The reel 30 has a spring core 32 incorporated in a substantially concentric and relatively rotatable state on the inner periphery of the reel body 31, and one end fixed to the reel body 31 and the other end fixed to the spring core 32. A spiral spring 33 that urges the main body 31 in the winding direction of the black ink thread 1 is provided. 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.
[0014]
A ratchet gear (not shown) is formed on the outer peripheral surface of the portion of the charge handle 35 inserted into the spool case 20, and the ratchet pawl is formed on the inner peripheral surface of the annular ratchet member 36 disposed on the outer periphery. (Not shown) is formed, and when the ratchet pawl is engaged with the ratchet gear, the spring core 32 (charge handle 35) rotates only in the direction of accumulating the spiral spring 33 with respect to the ratchet member 36. Can be done. 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.
[0015]
Therefore, when the reel body 31 is rotated in the feeding direction of the ink strike thread 1, the ratchet gear on the outer peripheral surface of the charge handle 35 is engaged with the ratchet pawl of the ratchet member 36 that is prevented from rotating around the clutch member 37. Since the rotation of the spring core 32 in the feeding direction is prevented, 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.
[0016]
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 displacing the coil spring 38 in the compression direction (rightward direction in FIG. 2) by manual operation of 37c, the collision protrusion 36a is disengaged. For this reason, the ratchet member 36 rotates together with the charge handle 35 (spring core 32) engaged with the ratchet member 36 in the biasing direction by the spiral spring 33, and when the ratchet member 36 rotates 180 °, Stops by colliding with the mating protrusion 37b. 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, so that the ratchet member 36 has the charge handle 35 (spring core). 32) together with the spiral spring 33, the rotation is again performed, and when the rotation is rotated 180 °, the abutting protrusion 36a is engaged with the one of the abutting protrusions 37a again to stop. 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.
[0017]
A mass body 40 made of an elongated metal piece is provided on a part of the outer circumference of the reel body 31 in the circumferential direction. The mass body 40 has a small hole formed at one end 41 inserted into a shaft 31a formed on one side plate of the reel body 31, whereby the reel body 31 swings in the radial direction about the shaft 31a. The edge of the reel body 31 facing the outer peripheral side has a shape in which a portion that is unevenly distributed toward the one end 41 protrudes, so that this portion is the lower half of the bobbin winding case 20. The sliding part 42 is slidable with the inner peripheral surface 26 of the case member 20B, and the free end 43 side is formed in an arc shape that is curved in the circumferential direction of the reel body 31 substantially.
[0018]
That is, the rotating part including the reel body 31 is located at a position where the center of gravity is slightly shifted from the axial position to the mass body 40 side by providing the mass body 40 at a part in the circumferential direction on the outer peripheral portion thereof. For this reason, radial vibration is generated during rotation. Further, when the reel body 31 is rotated, as shown in FIG. 4, the mass body 40 is swung toward the outer periphery around the shaft 31 a by centrifugal force, and the sliding portion 42 is the lower half case member 20 </ b> B in the bobbin winding case 20. It slides on the inner peripheral surface 26 of the.
[0019]
The ink brush having the above-described configuration, like the prior art, pierces Karuko 2 at the starting point of inking, and then moves the inking ink to a predetermined position to feed out the inking thread 1 by the moving distance of the inking ink. The inking process is performed by flicking the inking thread 1 to which the inking ink has adhered in the process with a finger toward the surface to be inked. 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.
[0020]
In the above-described yarn winding process, when the rotation of the reel body 31 that rotates in the yarn winding direction is accelerated , the center of gravity of the rotating unit including the reel body 31 is biased by the mass body 40. And a part of the rotational force is converted into a radial motion, so that an increase in rotational speed can be suppressed. And the deceleration action by this becomes so remarkable that the eccentric amount of the gravity center of the rotation part by the mass of the mass body 40 is large.
[0021]
Further, the mass body 40 is swung toward the outer periphery around the shaft 31a by the centrifugal force, and the sliding portion 42 slides with the inner peripheral surface 26 of the lower half case member 20A of the bobbin winding case 20. The frictional resistance generated by the above also suppresses the increase in rotational speed. Moreover, the sliding portion 42 is formed at a position from the shaft 31a that is a fulcrum, and generates a large frictional resistance due to the action of the lever. The frictional resistance increases as the mass of the mass body 40 increases. It increases as the speed increases. Therefore, even when the ink-dried yarn 1 is drawn out long to strike a long ink line, the acceleration of the rotation of the reel body 31 is limited when the ink-made yarn 1 is wound, and the karuko 2 moves toward the ink-jet side. The danger of flying inward is effectively prevented.
[0022]
In addition, this invention is not limitedly interpreted by embodiment of illustration. For example, the mass body 40 is provided integrally with a part of the reel body 31 in the circumferential direction so that the center of gravity of the rotating portion including the reel body 31 is decentered to generate radial vibration during rotation. Even so, it is possible to effectively limit the rotation or the increase in the rotation speed when winding the yarn. In the above-described embodiment, the mass body 40 is made of a metal piece. However, for example, a high specific gravity material such as lead may be integrated in the vicinity of the free end of the swing piece made of synthetic resin.
[0023]
【The invention's effect】
As described above, according to the ink brush of the present invention, since the acceleration of the reel rotation is limited during the automatic winding of the ink drum by the urging force of the spiral spring, Can be prevented from flying toward the ink jet side, or the flying speed can be remarkably reduced to improve work safety.
