Abstract

<P>PROBLEM TO BE SOLVED: To prevent a printing element from being damaged by stationery or the like entered from the opening of a seal or being stained by ink. <P>SOLUTION: A side plate part 71d is folded and erected through a folding part 71e on both sides of a shielding plate 71 comprising a shutter that shields the printing face of a printing element, with rigidity thereby improved against an external pressure. As a result, even if strongly pressed to the printing face side, the shutter member withstands an external pressure without bending to the printing face, eliminating problems in which the printing face is brought into contact with the shielding plate 71 and stained with the ink and in which a locked state is released by the bending, with evaporation of the ink accelerated to give rise to a sealing defect. In addition, since no warping is generated when the shutter is opened/closed for approximately 100,000 times, the locked state is free from loosening, which eliminates tendency of sealing defect through the acceleration of the ink evaporation or a problem of a printing face stained with the ink by stationery or the like entering from a lock-loosened place and coming into contact with the printing face. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a stamp provided with a porous printed body having countless continuous pores.

A stamp main body provided with a porous printed body having countless continuous pores, and the tip is always positioned ahead of the printing surface of the printed body due to the elastic force of the resilient member that is fitted in the front part of this stamp main body. The leg frame body is provided in the leg frame body, and the tips are normally in contact with each other so as to conceal the print body. A stamp comprising a shutter member made of a pair of shielding plates is already known (see, for example, Patent Documents 1 and 2).
However, in such a conventional stamp, since the shutter member shields the tip of a pair of shielding plates against each other, a mechanical pencil, a ballpoint pen, a pencil, a thousand sheets, etc. are used in a drawer pen case or a carrying pencil case. When storing stamps together, if a stationery such as a mechanical pencil, ballpoint pen, pencil, or a thousand sheets enters through the stamp opening of the stamp due to opening / closing operation of the drawer or vibration during carrying, it is easily inserted from the butt edge. There is a problem that the ink is released and the evaporation of the ink is promoted to easily cause a defective printing, and the stationery comes into contact with the printing surface and is soiled by the ink.
In order to solve such a problem, the applicant of the present invention previously disclosed, as disclosed in Japanese Patent Application Laid-Open No. 2006-205440, the engaging protrusion of one shielding plate is the other shielding plate as a shutter that conceals the printing surface of the printing body. Proposed a seal that engages the engagement receiving edge of the other shield plate and the engagement edge of the other shielding plate engages with the engagement projection piece so that the leading edges of both shielding plates are held in a locked state did.
However, in this stamp, when the shutter member is pressed strongly and pushed into the marking surface, the shielding plate itself is originally designed as a deformable flat plate, so it can not withstand external pressure and bends toward the marking surface. There is a problem in that the locked state is released when the stamping surface comes into contact with the ink or is bent or bent, and the evaporation of the ink is promoted to easily cause imprinting failure. Also, stationery stored in the same place. There is a problem that the ink comes into contact with the printing surface and is soiled by ink. Furthermore, there is a problem that when the pointed stationery is inserted from the part where the locked state is released, the stamp face is damaged and the imprint is lost. This problem is also clear from the fact that a lower-pointed auxiliary protrusion is provided as needed to prevent the shutter member from being pushed in even if it is pressed more strongly (described in paragraph number 0011 of Patent Document 3). It is.
In addition, when the shutter is opened and closed repeatedly about 100,000 times, warpage occurs and the locked state is loosened. There was a problem that stationery invaded from the loosened part of the paper and contacted the stamped surface and was soiled by ink. Even if the shielding plate is designed with a curved surface instead of a flat plate, if the thickness is reduced to reduce the weight, the rigidity will decrease, and if it is strongly pressed from the outside and pushed into the marking side as described above, There was a possibility that it could not withstand the external pressure and was bent toward the marking surface.
No. 7-26127 Japanese Patent Publication No. 7-90871 JP 2006-205440 A

  The present invention solves the above-described problems and provides a stamp with improved shielding plate rigidity. Even if the shielding plate is designed to be thin, rigidity is maintained against the force from the outside, and no warping occurs even if the shutter is opened and closed repeatedly about 100,000 times. This prevents the shutter from being opened except during the stamping operation, so that the printed material is not damaged by the stationery that has entered through the opening, or the stationery that has entered does not come into contact with the printing surface and become soiled by ink. It is intended to provide.

The stamp of the first invention completed in order to solve the above problems is a stamp main body provided with a porous print body having countless continuous pores, and is normally fitted to the front part of this stamp main body. A leg frame whose tip is positioned ahead of the printing surface of the printing body due to the resilient force of the bullet member, and a tip which is provided in the leg frame and is always in contact with each other so as to conceal the printing body. In a stamp comprising a shutter member made up of a pair of shielding plates that are opened in a printable state in conjunction with the lowering of the stamp main body accompanying the stamping operation, the side plate portions are disposed on both sides of the both shielding plates via bent portions. It is characterized by bending up.
According to a second aspect of the present invention, the tip of one shielding plate of the shutter member is an uneven edge composed of an engagement protrusion and an engagement receiving edge having a width equal to or larger than the base width thereof, and the other shielding plate has The front end is formed on the engaging projection piece of the above-described one shielding plate, the engagement receiving edge corresponding to the engagement receiving edge, and the concavo-convex edge composed of the engaging projection piece. The stamp according to the first aspect of the invention is characterized in that it is held in a locked state as a latching set portion in which the uneven edges are engaged with each other.

  Such a stamp is the same as this type of conventional stamp that the printed surface of the printed body is concealed by the shutter at all times except during the stamping operation. However, the shutter of the present invention uses the printed surface of the printed body. Since the side plate portion is bent upright on both sides of the shielding plate constituting the concealed shutter via the bent portion, the rigidity against the external pressure is improved. Here, “improvement” means that the degree of resistance to bending by the force from the outside is stronger than the case of the same material and the same thickness. In the case of reducing the thickness, the one in which the side plate portion is bent up via the bent portion has high rigidity even at the same thickness. Therefore, even if the shutter member is strongly pressed to the marking surface side, it cannot withstand the external pressure and does not bend toward the marking surface side. The problem that the ink evaporation is promoted and the printing failure is likely to occur is not caused. Further, since the shutter is not opened except during the stamping operation, the printed material is not damaged by the stationery that has entered from the opening, and the stationery that has entered does not touch the printing surface and become soiled by ink. In addition, since the warpage does not occur even if the shutter is opened and closed repeatedly about 100,000 times, the lock state does not loosen, the evaporation of the ink is promoted, and a printing defect is likely to occur. There is no problem that stationery enters from a place where the state is loose, contacts the stamp surface and is soiled by ink.

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.
The leg frame body 1 is a plastic hollow cylindrical shape whose upper and lower end surfaces are open, and a mounting cylinder 2 described later is detachably attached to the lower end. A ring-shaped flange portion 11 extending inward is extended from the upper end portion of the leg frame body 1, and a plurality of locking ribs 12 are provided on the lower inner peripheral surface of the leg frame body 1.

  The interior body 3 is inserted into the leg frame body 1 so as to be movable up and down. The interior body 3 is a plastic hollow body having upper and lower end surfaces opened, and includes a columnar large-diameter portion 31 having a predetermined diameter, and a columnar small-diameter portion 32 having a smaller diameter than the large-diameter portion 31 and a cylindrical shape. It has a shape. The outer diameter of the small diameter portion 32 is approximately the same as the inner diameter of the flange portion 11. The inner body 3 stops at a position where a step portion 33 formed on the connecting surface of the large diameter portion 31 and the small diameter portion 32 abuts on the locking rib 12 of the leg frame body 1 inside the leg frame body 1. It cannot move any further. A stamp main body 5 is detachably fitted in the large diameter portion 31, and a locking claw 34 is provided on the inner wall surface of the interior body 3 to be fitted to an outer frame body 4 described later.

  The stamp main body 5 holds a printing body 51 made of porous rubber having continuous pores by a metal receiver 53 below the main cylinder portion 52, and the marking surface of the printing body 51 is exposed at the lower end. In the stamp main body 5, the flange face 54 provided at the upper peripheral edge of the main cylinder portion 52 and the fitting rib provided in the large-diameter portion 31 of the interior body 3 are press-fitted with the marking surface facing downward. Can be attached detachably.

  The outer frame body 4 is a plastic double cylinder body integrally formed by hanging an inner cylinder 42 coaxial with the outer cylinder 41 downward from the top surface inside the outer cylinder 41 whose lower end is open. Is done. The outer diameter of the inner cylinder 42 is substantially the same as the inner diameter of the small-diameter portion 32 of the interior body 3, and the lower outer peripheral surface of the inner cylinder 42 faces the locking claw 34 of the interior body 3. A fitting recess 43 is provided at the position. The outer frame body 4 is assembled in a state where the elastic member 6 is disposed on the upper end surface of the flange portion 11 of the leg frame body 1 in which the interior body 3 is housed, and the lower end of the inner cylinder 42 is placed on the elastic body. The engaging claw 34 provided on the inner wall surface of the interior body 3 is fitted into the fitting recess 43 through the emitting member 6 and the upper end opening of the small diameter portion 32 protruding from the upper end opening of the leg frame body 1. As a result, the outer frame body 4 is attached to the interior body 3. Thereby, the outer frame body 4 is connected and integrated with the interior body 3 in a state of covering the upper outer periphery of the leg frame body 1, and the elastic member 6 is connected to the lower end of the top surface of the outer frame body 4. And the flange 11 of the leg frame body 1 are sandwiched between the upper end surface of the leg frame body 1, and by the action of the elastic member 6, the interior body 3 together with the outer frame body 4 is always upward with respect to the leg frame body 1. It is energized. Here, cooperation means that two objects move together, and in this embodiment, a coil spring is used as the resilient member 6.

  The leg frame 1 is always in contact with the tips so as to conceal the printing body 51, but a pair of left and right that are opened in a stampable state in conjunction with the lowering of the interior body 3 accompanying the stamping operation. A mounting cylinder 2 having a shutter member 7 composed of shielding plates 71 and 71 mounted therein is detachably connected. The mounting cylinder 2 has an upper cylinder 21 formed in the middle with an outer collar 21a that is locked at the lower edge of the leg frame 1, and an inner flange 22a that is locked at the lower edge of the upper cylinder 21 substantially upward. The formed lower cylinder 22 is fitted. The shielding plate 71 has a mounting piece 71g inserted into a pocket portion 23 provided in the lower cylinder 22, and a notch 24 provided at a position opposite to the pocket portion 23 at the lower end of the upper cylinder 21. Is attached between the upper cylinder 21 and the lower cylinder 22 in a retaining shape. In the illustrated example, the attachment piece 71g is inserted and attached to the pocket portion 23 formed between the upper cylinder 21 and the lower cylinder 22, but the attachment piece 71g is not attached to such a double cylinder but inside the single cylinder. May be attached. It should be noted that the replacement of the stamp main body 5 is performed by removing the mounting cylinder 2 from the leg frame 1.

The shutter member 7 includes a first embodiment in which the marking surfaces are shielded by overlapping each other and a second embodiment in which the front ends of a pair of shielding plates are brought into contact with each other for shielding. First, the first embodiment. It explains from.
The shutter member 7 according to the first embodiment has a pair of left and right edges having concavo-convex edges composed of engagement protrusions 71a and engagement receiving edges 71b that are different in phase so as to be alternately overlapped and shield the marking surface. The shield plate 71 is made of a substantially semicircular shape. The locking assembly 72 is assembled at only one place between the engagement protrusion 71a and the engagement receiving edge 71b of the shielding plate 71, and the pointed stationery is one point where the pointed stationery easily enters. The effect of reducing the product cost by reducing the possibility of the intrusion and making the shape simple by using an inexpensive mold or press mold. A mounting piece 71g is formed on the base via a hinge 71f. The material of the shielding plate 71 is not limited as long as sufficient durability can be obtained with respect to repeated opening and closing operations. In the embodiment, however, the shielding plate 71 is made of a strong synthetic resin material such as polypropylene resin. It is supposed to be.
In addition, the left and right shielding plates 71 are engaged with each other when the concavo-convex edges formed by the engaging protrusions 71a and the engaging receiving edges 71b having different phases are alternately overlapped and engaged. The stopper assembly 72 is assembled, and thus the elastic force acting in the folding direction of the shielding plate 71 is received by the locking assembly portions 72 of the left and right shielding plates 71, 71. A strong space strong against tensile force and pressing force is formed between the lock and the marking surface.
Further, on both sides of the substrate portion 71c provided at the center of the shielding plate 71, the side plate portion 71d is bent up to the printing surface side via the bent portion 71e and is erected. In this embodiment, since the two bent portions 71e are formed symmetrically with respect to the substrate portion 71c, a part of the substantially circular circumference so that the cross-sectional shape of the shielding plate 71 is along the inner peripheral surface of the lower cylinder 22. (See FIG. 8). Thus, when the cross-sectional shape of the shielding plate 71 is made close to a circle, there is no obstacle when the stamp main body descends due to the stamping operation, and the outer periphery of the stamp main body 5 can be made as close as possible to the inner periphery of the lower cylinder 22. Can be efficient without waste. However, the number of the bent portions 71e may be singular or plural, and the number is not limited.
The shield plates 71 and 71 are automatically pushed and opened against the elastic force by contacting the receiving body 53 of the stamp main body 5 that is lowered during the stamping operation. Further, the engaging protrusion 71a of the shielding plate 71 has an arc shape with its protruding edge having no corners. By making the arc shape in this way, the engagement is smoothly performed when overlapping the other shielding plate 71. This is done so that no shielding failure occurs.
The interior body 3 and the outer frame body 4 are elastic springs such as coil springs whose front ends are brought into contact with the locking ribs 12 of the leg frame body 1 and whose rear ends are brought into contact with the inner upper ends of the outer frame body 4. It is energized by the emitting member 6 to raise the stamp main body 5 so as to be accommodated in the leg frame 1 and to release the shutter member 7 by being pressed by the receipt 53 of the stamp main body 5. By doing so, the shutter member 7 engages and locks the left and right shielding plates 71 and 71 by its elastic force to firmly shield the printing surface, so that even if another object enters, it is shielded. The plate 71 is not inadvertently opened, protects the marking surface accurately, and prevents other objects from touching the marking surface and causing contamination. When the stamping operation is performed, the lower end edge of the mounting cylinder 2 is brought into contact with the paper surface, and the outer frame body 4 is pressed to lower the stamp main body 5 against the urging force of the elastic member 6. Since the bases of the left and right shielding plates 71 and 71 attached to the mounting cylinder 2 are pressed by the receiver 53 of the main body 5, the shutter member 7 is opened, and the printing body 51 comes into contact with the paper surface and is stamped. It will be.

When stamping the printing body 51, the stamp configured as described above is an interior body that cooperates with the outer frame body 4 with the lower end edge of the mounting cylinder 2 abutting on the paper surface as shown in FIG. When 3 is pressed against the elastic force of the elastic member 6 and pressed down, the shutter member 7 is opened by the metal receiving 53 of the stamp main body 5 and the printed body 51 is exposed from the lower end opening of the mounting cylinder 2. 2 to reach the position shown in FIG. When the stamping is completed and the pressure on the outer frame body 4 is released, the interior body 3 that cooperates with the outer frame body 4 rises in the leg frame body 1 through a process opposite to that of the lowering, and the shutter The member 7 returns to the closed position.
One shielding plate 71 is provided as a shutter member 7 provided in the mounting cylinder 2 so as to conceal the printing body 51 at all times, but is opened in a state where the printing can be performed in conjunction with the lowering of the interior body 3 accompanying the marking operation. And a leading edge of the other shielding plate 71 is the leading edge of the other shielding plate 71. What is formed on the concavo-convex edge composed of the engagement receiving edge 71b and the engagement protrusion 71a whose phases are different from each other in correspondence with the engagement protrusion 71a and the engagement reception edge 71b is used. Is held in a locked state by a locking set 72 in which the concavo-convex edges at the front end of the shutter member 7 are engaged with each other. , The surrounding area may be soiled by the marking surface, or the marking surface may dry. Needless to say, there are no sharp pencils, ballpoint pens, sharp-pointed stationery, such as a thousand-thru holes, and even if the locking assembly 72, which is the contact portion of the shielding plates 71, 71, penetrates from the stamping opening, Since the shield plates 71 and 71 are alternately stacked, the printing surface is not opened from the contact portion. Therefore, the printing surface is accurately prevented so that the stationery is not inserted from the abutting surface and the printing surface is not damaged. Will be protected.
Moreover, since the uneven edges of the shielding plates 71 and 71 are elastically pressed against each other, the sealing performance is high, and evaporation of ink or the like can be prevented more reliably. Further, the shape of the engagement protrusions 71a, 71a of the shielding plates 71, 71 is not particularly limited. However, when the protrusions have an arc shape, the shielding plate is 71 in conjunction with the stamping operation. When 71 is closed and the locking assembly 72 is formed, the leading edges of the engaging projections 71a and 71a of the shielding plates 71 and 71 are smoothly moved to the engagement receiving edges 71b and 71b along the arc. Therefore, it is particularly preferable that the corner portion is caught and the shielding is not incomplete.

Furthermore, since the side plate portion 71d is bent and raised on both sides of the shielding plate via the bent portion 71e, the rigidity against external pressure is improved as compared with the case where the side plate portion 71d is not bent and raised. For this reason, even if the shutter member 7 is strongly pressed to the marking surface side, it does not endure the external pressure and does not bend toward the marking surface side, and the marking surface comes into contact with the shielding plate 71 and is damaged by ink or bent. There is no problem that the locked state is released and the evaporation of the ink is promoted so that a printing defect is likely to occur. Further, since the shutter is not opened except during the stamping operation, the printed material is not damaged by the stationery that has entered from the opening, and the stationery that has entered does not come into contact with the printing surface and is not soiled by ink.
Accordingly, it is possible to provide a stamp that eliminates the possibility of opening the shutter as much as possible except during the stamping operation.

Next, although the shutter member 7 of 2nd Embodiment is demonstrated, only a different point from above-described 1st Embodiment is demonstrated here.
The shutter member 7 of the second embodiment is the same as the shutter member of the first embodiment, except that there are no irregularities at the leading edges of both shielding plates, and shielding is performed by abutting the tips of a pair of shielding plates. It is. Although this embodiment is not illustrated, the configuration of the tip edge is substantially the same as that of FIG. 1 of Patent Document 2 except that the side plate portion is bent upright on both sides of the shielding plate via the bent portion.
Since the stamp configured in this manner has the side plate portions bent up on both sides of the shielding plate via the bent portions, the rigidity against external pressure is improved as compared with the case where the side plate portions are not bent up. For this reason, even if the shutter member 7 is strongly pressed to the marking surface side, it does not endure the external pressure and does not bend toward the marking surface side, and the marking surface comes into contact with the shielding plate 71 and is damaged by ink or bent. There is no problem that the butt is not aligned. Moreover, compared with the case of Patent Document 2 in which the shielding plate is designed with a curved surface, the rigidity is greatly improved against an external pressure that is strongly pressed from the outside.

  Although the present invention has been described with reference to the above embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the scope of the present invention. is there.
