Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to the improvement of a stamp using a stamp 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,
The adjustment member rotates little by little due to repeated stamping operations. There was a problem that the upper limit position of the slide member could not be maintained at a predetermined 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 sliding member is provided with a sliding member, a female screw portion and an annular inner eaves are formed on the inner circumferential surface of a decorative cylinder portion surrounding the outside of the shaft portion, and a large number of locking recesses are arranged on one end surface of the annular inner eaves. a stop ring that is fitted into an intermediate portion of the shaft portion so as to allow only vertical sliding and that engages and disengages the locking convex portion in the locking recess; and a stop ring that is surrounded by the shaft portion; a spring that springs the locking convex portion of the stop ring toward the locking recess; and a gripping cap that is fitted onto the tip of the shaft portion with a connecting cylinder portion at the lower end; A male threaded portion formed on the outer circumferential surface of the rising portion of the sliding member or the outer circumferential surface of the connecting cylinder portion of the gripping cap is screwed into the female threaded portion of the adjustment member and engaged by the elastic force of the spring. The present invention is characterized in that the upper limit position of the slide member is finely adjusted by forcibly rotating the adjusting member whose rotation is restricted by the locking recess and the locking convex portion.

(Function) This kind of stamp is normally made by holding the gripping cap and bringing the leg end of the outer mantle 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., rotate the adjustment member to finely adjust the upper limit position of the slide member, and then 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 countless continuous pores made of porous rubber or the like is attached with an ink absorbing plate 4a attached to the upper side thereof.
Further, a key groove 5 is provided in the outer surface of the shaft portion 3 in the axial direction. Reference numeral 6 denotes a slide member 6, and the slide member 6 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 portion 3 is inserted and a short cylindrical rising portion 9 surrounding the hole 8.
It is assumed that 10 is the rising part 9
The adjusting member 10 has a female threaded portion 12 formed in about half of the inner peripheral surface of the decorative cylinder portion 11 surrounding the shaft portion 3 and the rising portion 9, and has an annular threaded portion formed in the remaining portion. It is made of synthetic resin and has an inner eave part 13 formed therein, and a large number of arcuate locking recesses 14 are arranged on one end surface of the annular inner eave part 13. 15 has the locking convex portion 1 on one end surface.
The stop ring is made of synthetic resin and has a plurality of locking convex portions 17 that can be freely engaged and detached from the stop ring 4, and a key 16 that is engaged with the key groove 5 on the inner peripheral surface. is housed in the adjusting member 10 in a state in which it is fitted into the intermediate portion of the shaft portion 3 so that it can only be slid vertically but not rotated. Reference numeral 18 denotes a coil-shaped spring that is surrounded by the shaft portion 3 and springs the stop ring 15 toward the annular inner eaves portion 13, and the locking convex portion 17 is normally locked by the elastic force of the spring 18. It is engaged with the recess 14 for use. Reference numeral 19 denotes a gripping cap that is fitted onto the tip of the shaft portion 3 with the connecting cylinder portion 20 at the lower end, and its hem end covers the upper portion of the adjustment member 10 from the outside. In addition, 21 is the adjustment member 1
In the first embodiment shown in FIGS. 1 and 2, the adjusting member 10 has the male threaded portion 12 on the lower side and the shaft portion 3 and the rising portion 9. and a locking recess 1
4 is disposed on the upper end surface of the annular inner eaves portion 13, since the stop ring 15 is located above the annular inner eave portion 13.
Although the male screw portion 21 is interposed between the slide member 18 and the stop ring 15 and the receiving portion 22 of the gripping cap 19, as in the second embodiment shown in FIGS. 10 surrounds the shaft 3 and the rising portion 9 with the female threaded portion 12 on the upper side, and the stop ring 15 is located below the annular inner eaves portion 13 which has the locking recess 14 on the lower end surface. A male threaded portion 21 is formed on the outer peripheral surface of the connecting cylinder portion 20 of the gripping cap 19, and the spring 18 is interposed between the annular inner eaves portion 13 of the stop ring 15 and the upper surface of the outer mantle portion 7. In the first embodiment, the distance S between the upper end of the adjusting member 10 and the stopper 23 in the gripping cap 19 is
In addition, in the second embodiment, the distance S between the lower end of the adjustment member 10 and the upper surface of the outer mantle 7 of the slide member 6 is finely adjusted by forced rotation of the adjustment member 10, and the upper limit position of the slide member 6 is set. is regulated.

In both embodiments, when the gripping cap 19 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. Furthermore, the locking convex portion 17 of the stop ring 15, which is only allowed to slide up and down relative to the shaft portion 3 and is prevented from rotating, is located in the locking recess 14 provided in the annular inner eaves portion 13 of the adjustment member 10. Since the adjusting member 10 is engaged under the elastic force of the spring 18, the adjusting member 10 will not be rotated unless it is forcibly rotated against the elastic force of the spring 18. There is no possibility that the upper limit position of the slide member 6 will change due to rotation of the adjustment member 10.

(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.
