Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to the improvement of a stamp using a printing body made of a porous stamp material having numerous continuous pores.

(Prior art) A stamp is made of a porous stamp material such as sponge rubber that has countless continuous pores so that it can absorb ink, so that there is no need to apply ink each time it is used. Because it is flexible, depending on the amount of ink stored in it, excessive ink may seep out onto the printing surface, making it difficult to print clearly. In order to eliminate such defects, a system in which an adjustment member is screwed in to adjust the lifting limit position of the slide member whose leg end is always located below the printing surface of the porous stamp material was proposed in Japanese Utility Model Publication No. 53-44486, etc. has been done.

(Problem to be solved by the invention) However, since the adjustment member for conventional stamps of this type cannot be equipped with a stop mechanism,
There was a problem in that the adjustment member rotated little by little due to repeated stamping operations, and the slide member could not be maintained at a predetermined ascending limit position.

(Means for Solving the Problems) The present invention relates to a stamp that solves the above-mentioned problems, and uses a porous stamp material having countless continuous pores on the bottom surface of a stamp material holding frame with a shaft portion on the top surface. The attached stamp main body, a hole through which the shaft is inserted into the upper surface of a mantle frame that covers the stamp material holding frame so that the leg end is located below the printing surface of the porous stamp material, and a rising portion surrounding the hole. A gripping cap is fitted with a connecting cylinder portion at the lower end having a male threaded portion formed in the lower half thereof, and a female threaded portion is formed on the inner peripheral surface to be screwed into the male threaded portion. The adjustment member includes an annular inner eaves portion formed below the adjusting member, and a spring interposed between the annular inner eaves portion and the upper surface of the slide member. An elastic pawl piece with a removable locking convex portion is provided in a locking recess formed on the inner circumferential surface of the rising portion of the slide member or on the outer circumferential surface of the connecting cylinder portion of the gripping cap. The upper limit position of the slide member is finely adjusted by forced rotation of the adjusting member whose rotation is limited by the locking recess and the locking protrusion engaged by the elastic force of the slide member. It is characterized by this.

(Function) This kind of stamp is normally made by holding the gripping cap and bringing the leg end of the outer frame of the slide member into contact with the surface to be stamped, and then applying a pressing force, the slide member resists the spring force. As with conventional stamps of this type, the porous stamp material's printed surface comes into contact with the surface to be stamped and is stamped. If the amount of ink leaking onto the printing surface is too large or too small depending on the amount of ink occlusion, etc., the adjustment member is rotated to finely adjust the upper limit position of the slide member, and the printing surface is The pressing force on the surface to be stamped may be set to the optimum condition for clearly stamping.

(Embodiment) Next, the present invention will be explained in detail with reference to the illustrated embodiment. 1 is a stamp main body;
A cylindrical shaft portion 3 is integrally molded at the center of the upper surface of a square stamp material holding frame 2 made of a synthetic resin material with plate-like legs integrally molded from both sides of a square top plate portion, and further, the stamp material holding frame 2 A porous stamp material 4 having numerous continuous pores made of porous rubber or the like is mounted on the top thereof with an ink absorbing plate 4a attached thereto. Reference numeral 6 denotes a slide member, and the slide member 6 has the shaft portion on the upper surface of the outer mantle frame 7, which has a top plate portion and plate-like leg portions that are slightly larger than the top plate portion and plate-like leg portions of the stamp material holding frame 2. A hole 8 through which the hole 3 is inserted and a short cylindrical rising portion 9 surrounding the hole 8 are provided. Reference numeral 10 denotes an adjustment member provided on the outside of the rising portion 9, and the adjustment member 10 includes a decorative cylindrical portion 11 surrounding the shaft portion 3 and the rising portion 9.
It is made of synthetic resin and has a female threaded portion 12 formed in the upper half of the inner peripheral surface thereof and an annular inner eaves portion 13 formed below the female threaded portion 12. Reference numeral 15 denotes a gripping cap that is fitted onto the tip of the shaft portion 3 with a connecting cylinder portion 16 at the lower end, the hem end of which covers the upper part of the adjustment member 10 from the outside, and the connecting cylinder A male threaded portion 17 is formed in the lower half of the outer peripheral surface of the portion 16,
18 is a coil-shaped spring surrounded by the shaft portion 3 and interposed between the annular inner eaves portion 13 and the upper surface of the slide member 6; 19 is a locking convex provided at the end of the adjustment member 10; The locking protrusion 20 of the elastic claw piece 19 is formed vertically on the inner peripheral surface of the short cylindrical rising part 9 of the slide member 6 and has an arc-shaped cross section. The elastic claws are attached to a large number of locking recesses 14 having an arcuate cross section formed vertically in the upper half of the outer peripheral surface of the connecting cylinder portion 16 of the gripping cap 15. It is said that it can be freely engaged and detached by the elastic force of the piece 19.
That is, in the first embodiment shown in FIGS. 1 and 2, the elastic claw piece 19 is provided at the upper end of the adjustment member 10, while the locking recess 14 is provided on the connecting cylinder portion 16 side. In the second embodiment shown in FIGS. 3 and 4, an elastic claw piece 19 is provided at the lower end of the adjustment member 10, while a locking recess 14 is provided on the inner peripheral surface of the rising portion 9 of the slide member 6. I take it as a thing. In both embodiments, the adjusting member 10 finely adjusts the distance S between the lower end and the upper surface of the mantle frame 7 of the sliding member 6 by forced rotation of the adjusting member 10.
The upper limit position of the rise is regulated.

In both embodiments, when the gripping cap 15 is gripped and the stamp is stamped, if the amount of ink seeping into the printing surface is too large, the adjusting member 10 If the space S is reduced by forcibly rotating, the portion of the printed surface of the porous stamp material 4 that protrudes from the leg end of the slide member 6 during the stamping operation will be reduced, so that excessive pressing force will not be applied to the stamped surface. A clear stamp can be made without adding anything. On the other hand, if the amount of ink leaching onto the printing surface is small, by forcibly rotating the adjustment member 10 in the opposite direction to increase the distance S, the printing surface of the porous stamp material 4 can be moved closer to the slide member 6 during the stamping operation. Since the portion protruding from the leg end is large, a large pressing force is applied to the surface to be stamped, resulting in a clear stamp. Moreover, the locking convex portion 20 provided on the elastic claw piece 19 at the end of the adjusting member 10 is located on the inner surface of the rising portion 9 of the slide member 6 or on the upper half of the outer circumferential surface of the connecting cylinder portion 16 of the gripping cap 15. The adjustment member 10 can be freely engaged with and detached from a large number of locking recesses 14 having an arcuate cross section formed in the vertical direction by the elastic force of the elastic claw pieces 19.
is not rotated unless it is forcibly rotated against the elastic force of the elastic claw piece 19. Therefore, during the stamping operation, the adjustment member 10 is automatically rotated to bring the slide member 6 to its upper limit position. There is nothing that will change anything.

(Effects of the invention) As is clear from the above description, the present invention adjusts the raising limit position of the slide member by rotating the adjustment member so that a pressing force corresponding to the amount of ink stored in the porous stamp material is applied to the printing surface during the stamping operation. Since it can be finely adjusted by moving the slider, it is possible to always make clear stamps, and since the adjustment member is not rotated unless necessary, the upper limit position of the slide member can be maintained at a predetermined position. It is of great practical value as it solves the problems of conventional seals of this type.
