[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a seal stamp using a printing body made of a porous stamp material having countless continuous pores.

[0002]

2. Description of the Related Art Conventionally, it is not necessary to use a printing material formed of a porous stamping material having an infinite number of continuous pores such as sponge rubber so as to absorb ink, and to attach it to vermilion every time it is used. Seals are known. However, in the case of this type of seal, if the print surface is exposed, problems such as scratching of the print surface, adhesion of dust, and drying of the ink occur, so the print surface is covered with a cap. Therefore, not only is it troublesome to attach and detach the cap, but also there are problems such as losing the cap and erroneously soiling the hands when attaching and detaching.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a convenient seal which can solve the above-mentioned problems.

[0004]

In order to achieve the above object, the opening and closing seal of the present invention has been developed to achieve the above object. A movable shaft with a seal attached to the tip at the inner hole of the cap is freely movable, and a knock mechanism that positions the seal at the advance / retract position by knocking in conjunction with the movable shaft is located behind the cap. When the seal is arranged and knocked and the seal is advanced, the seal is opened and the seal is exposed from the opening while the corner of the seal contacts the inner surface of the cover, and the seal is knocked again. Is configured to recede and close the lid.

[0005]

1 and 3 show an embodiment of the present invention. First, as shown in FIG. 1 and FIG. 2, the seal 25 is made up of a printing body 43 formed of a porous printing material having an infinite number of continuous air holes such as sponge rubber so as to absorb ink and a printing body which stores ink. An ink occluding body (not shown) for supplying ink to 43 is disposed on the distal end surface of the shaft 27 of the leg 26, and the cover 29 is fixed to the shaft 27. The printing surface is exposed. A circumferential groove 45 is provided in a rear end hole of the leg 26.

The cap 9 is formed by bulging a base 11 having a U-shaped cutout on the side surface at the front end of a cylindrical body having an opening 10, and has a side surface of the base 11 located at the cutout. A small hole 12 is formed in a direction substantially perpendicular to the axis, and a groove 13 is formed near the rear of the small hole 12. Also, cap 9
A step 14 having a circumferential shape is provided at a substantially center position of the inner hole of the step 1.
A rib 15 is formed at an appropriate position behind the 4, and a female screw 16 is provided in a rear end inner hole. Also, the lid 17
Has a shaft support 18 formed at one end and a small hole 19
The shaft support portion 18 is further provided with a U-shaped concave portion in cross section. The notch (not shown) has a small hole 46 at the center, and a shaft 20 is inserted into a cut window of the base 11 in a state in which a spring 20 having a rod 21 at one end and a rod 22 at the other end is inserted. The support 18 is fitted therein, and the small hole 46 of the spring 20 is provided.
The pin 23 is fixedly connected to the small hole 19 formed in the side surface of the shaft support 18 and the small hole 12 of the base 11. Also, the spring 20
The rod shaft portion 21 is fixed to a groove (not shown) provided in the lid portion 17, the rod shaft portion 22 is fixed to the groove 13 of the base portion 11, and the lid portion 17 is connected to the opening 10 of the cap 9. The cover 17 is provided so as to be openable and closable in a state provided with a spring property, and the cover 17 is configured to always shield the opening 10.

On the other hand, the movable shaft 1 has a shaft cylinder at the front, and a projection 3 having a slope on the front surface at two places on the side at substantially the center of the cylinder, and a side surface substantially perpendicular to the projection 3. Are provided with slits 4 (usually at two places) so that when the protrusion 3 is pressed on the inner diameter side, it is appropriately elastically displaced toward the reduced diameter side. Also, the leg portion 2 of the seal is provided on a side surface near the tip of the barrel.
6 is formed with a circumferential projection 2 which engages with a groove 45 provided in the rear end hole of the cylinder to enable the seal to be fixed. The flange portion 5 is formed, a shaft portion 7 is extended behind the flange portion 5, and has a small diameter projecting shaft portion 8 at the rearmost end.

As described above, the movable shaft 1 is inserted from the rear end hole of the cap 9 with the return spring 24 biased between the front surface of the flange portion 5 and the step portion 14 formed in the inner hole of the cap 9. The groove 6 formed in the flange portion 5 is fitted in the rib 15 of the cap, and the projection 3 is locked on the front surface of the step portion 14 while being elastically reduced in diameter by the inner hole of the step portion 14. In this state, the movable shaft 1 is fixed to the cap 9 so that only the axial movement is possible.

A cam groove 34 and a cam portion 35 formed on the circumference are formed in an inner hole of the cam cylinder 31 having a male screw 33 on an outer periphery and a flange 32 at a rear end. Cam groove 34
A cam surface 36 is provided on the front surface of the cam portion 35 in an inclined manner. A cam portion 38 which fits loosely into the cam groove forward.
And a knock bar 37 having a cam surface 39 on the front side
The rear end of the knock bar 37 is fitted to the inner hole of the cam cylinder 31 and appropriately protrudes from the rear end of the cam cylinder 31. Further, a cam portion 41 and a rotor 40 having a cam surface 42 at the rear end thereof are loosely fitted to the front surface of the knock bar 37 by bringing the cam surface 42 into contact with the cam surface 39 of the knock bar, and the movable shaft 1 is at the rear end. The protruding shaft portion 8 of the rotor 40
The cam cylinder 31 is in contact with the bottomed hole at the tip and the male screw 3
3 is fixed to the female screw 16 at the rear end hole of the cap 9.
In addition, the knocking mechanism section composed of the rotor 40, the knocking bar 37, and the cam cylinder 31 knocks the writing section in and out.
This is equivalent to the well-known knock-type knock mechanism used in the well-known knock-type ballpoint pen, etc.Each time the rear end of the knock bar is knocked, the rotor is indexed and the rotor is rotated by the angle to move the rotor forward and backward. Are alternately positioned. Further, the cover portion 17 is expanded, and the seal 25 is provided with a groove 45 provided in the rear end hole of the leg portion 26 at the forward portion of the movable shaft 1.
And is locked.

[0010]

The openable seal of the present invention is constructed as described above. When not used, the cover 17 covers the printed body 43 when not in use, as shown in FIG. When stamping, knock bar 3
When the rear end of the seal 7 is knocked (axis shift), the seal 25 moves forward in conjunction with the movable shaft 1, the corner portion 44 of the seal 25 expands while contacting the inner surface of the cover 17, and the seal 25 is closed. It is exposed from the opening 10 of 9 and positioned and fixed. (See FIG. 2) In order to store the seal 25 again and close the lid 17, the rear end of the knock bar 37 may be knocked.

[0011]

[Effects of the Invention] The structure and operation of the openable seal of the present invention are as described above. Like a product in which the printing surface is covered with a conventional detachable cap, the cap is attached and detached every time it is stamped and lost. It can be used without any problems such as accidentally getting your hands dirty when attaching or detaching the cap, and when not in use, the printing surface is covered with the lid, so you can scratch it, Since there is no problem such as adhesion of dust and drying of the ink, and the seal can appear and disappear only by knocking, it is possible to provide a seal that is easy to use.
