Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink applicator in which an ink storage unit for transferring and applying ink to a stamp such as a rubber stamp which is not a self-contained ink is arranged, and more particularly to a stamp table.

[0002]

2. Description of the Related Art A conventional stamp table can be roughly divided into four parts, a stamp body, a lid container, a bottom container and a frame. Among them, the stamp body has a surface such as felt capable of being impregnated with ink covered with fibers such as cotton cloth and a bottom surface covered with a heat-fusible substance such as sheet-shaped vinyl chloride / polypropylene. At this time, the cotton cloth is heat-bonded to the sheet-shaped vinyl chloride, polypropylene or the like while applying tension.
Then, the tension causes the stamp body to warp upward with its surroundings upward. When such a stamp body is assembled, when the periphery of the stamp body is pressed by the pressing piece of the frame body and sandwiched between the bottom container and the bottom cloth, tension is further applied to the cotton cloth to make it difficult to mount. (See FIG. 4 of the conventional example) In addition to such a stamp pad, a cotton cloth is attached to the frame part, and the stamp body is pressed from above by this to stretch the board surface to form the stamp pad. The stamp stand assembled in this way was made by applying tension to the cotton cloth at the time of making the stamp body during the first time, but at the stage of using it, the cotton cloth will grow naturally with time and with the ink. The tension applied to the initial cotton cloth cannot be maintained due to the elongation caused by using the stamp. Regarding the cotton cloth tension, the end of the inner plate is sandwiched between the frame body and the bottom container, and the center part of the inner plate is made to be a convex part or the peripheral part is a concave part, and the stamp body itself is intentionally curved when assembled. The cotton cloth on the surface is tensioned to prevent the cotton cloth from wrinkling. There is Japanese Utility Model Application No. 4-113970 (hereinafter referred to as (a)) as such an application. In (a), the sawtooth-shaped uneven edges provided on the ribs pull the front cotton cloth, and further, the ribs and the concave portions of the bottom container are clamped and fixed, thereby obtaining the above-described cotton cloth tension effect. However, since the cotton cloth is pulled by the serrated edges and further clamped and fixed, the tension applied in the initial stage of assembly causes the cotton cloth to stretch each time the stamp is used, causing wrinkles on the surface. When it is clamped and fixed during use, it decreases and is not effective. When rubbed, wrinkles and irregularities are generated on the surface of the cotton cloth, and it is not possible to apply the ink uniformly on the surface of the stamp face, and it is not possible to obtain a clear impression.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
As described above, the cotton cloth itself swells due to the impregnated ink, the cotton cloth itself expands over time, and the cotton cloth expands due to contact when the stamp is used, causing wrinkles on the cotton cloth.
Due to this wrinkle, it is not possible to apply the ink uniformly on the stamp surface,
The point is that a clear and uniform imprint cannot be obtained. Therefore, the cotton cloth itself is always tensioned so that the ink can be uniformly applied to the stamp, a clear imprint is obtained, and the stamp base is easy to mold and easy to assemble.

[0004]

[Means for Solving Problems] Lid container 1, bottom container 2,
In the stamp base composed of the frame body 14 and the stamp body 3, a space portion 8 is formed on each of four walls to form a curved portion 7, and a U-shaped collar portion 9 located above the bottom 10 is provided around the outer wall 11. The middle plate 4 is arranged, the inclined surface 21 is provided at the lower end of the pressing piece 15 that comes into contact with the return wall 9B of the collar portion 9, the ink storage part 5 is arranged inside the middle plate 4, and the cotton cloth 6 is placed on this surface. It is stretched, the ends of the collar portion 9 and the cotton cloth 6 are heat-sealed to form the impression body 3, and the space S is provided, and the collar portion 9 is pulled outward by the pressing piece 15 of the frame body 14, Further, the stamp base is characterized by being pressed and abutted so as to be vertically swingable.

[0005]

The ink storage section 5 is arranged inside the inner plate 4, and while the cotton cloth 6 is stretched on the surface, the end of the cotton cloth 6 and the bottom 9A of the U-shaped collar portion 9 are heat-sealed. Then, the outer wall 11 and the inner wall 12
Is the middle plate 4 while expanding the space 8 and inclining the curved part 7 inward.
The collar portion 9 located above the bottom of the cartridge is lifted up more than when there is no load, and the ink storage portion 5 is pushed downward in the vicinity of the inner wall 12 so that cotton cloth can be laid on the stamp body 3 itself. Here, the inner plate 4 is provided with a taper portion 13 to absorb the tension when the cotton cloth is stretched, and to absorb the warp of the inner plate 4 due to the cotton cloth tension. Next, the stamp body 3 is housed in the bottom container 2, and the U-shaped brim portion 9 is pushed down by the pressing piece 15 having the inclined surface of the frame body 14 to be assembled. Then press piece 1
A space S is formed between the bottom container 5 and the bottom container 5 so that the collar part 9 can swing vertically and horizontally. At this time, the end of the return wall 9B is in contact with the inclined surface 21 provided on the pressing piece 15. In the assembled state of the frame body 14 and the stamp body 3, the outer wall 11 moves toward the inner wall 12 due to the downward pressing force of the pressing piece 15, and the strain (the tension for pulling the cotton cloth 6) increases. This is because if the collar portion 9 is located below the initial state in which the cotton cloth 6 is assembled and stretched, tension is applied to the cotton cloth 6. Here, the strain (tension for pulling the cotton cloth 6) is stored in the flange portion 9 from the taper portion 13, the inner wall 12 and the outer wall 11, and is described above with respect to the elongation of the cotton cloth 6 over time and the contact elongation due to the use of the stamp. Wrinkles of the cotton cloth 6 are prevented by releasing the stored tension by an amount corresponding to the extension. Further, when the cotton cloth 6 is wrinkled and the strain is reduced, the return wall 9B is in contact with the inclined surface 21 as described above, so that the U-shaped collar portion 9 and the outer wall 11 are provided along the inclined surface 21.
Is moved to the outside to expand the space 8. This operation is released only by the amount of extension, and when a stamp or the like is further used in the future, the outer wall 4 pulled into the inner wall 12 is returned outward, and the return wall 9B of the flange 9 and the pressing piece. Since the inclined surface 21 of 15 is in contact, the cotton cloth 6 can continue to be stretched by sliding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention will be described in detail with reference to FIGS. 1, 2, 3, 4, 5, and 6. Reference numeral 1 denotes a lid container, which is hinge-fitted to the bottom container 2. 3 is a stamp body, and its constituent parts are a middle plate 4, an ink occlusion part 5 and a cotton cloth 6.
It is composed of The reference numeral 4 is an inner plate, which is provided with curved portions 7 on the four sides by an inner wall 12 and an outer wall 11, and is further provided with a U-shaped collar portion 9 at the end portion. Outer wall 1 when no load
A collar portion 9 is located at an end of the upper portion of the inner plate 4 above the bottom 10 of the inner plate 4 and is parallel to the bottom 10. The collar portion 9 is provided around the entire circumference of the inner tray 12. At this time, the upper position is preferably 2 mm to 7 mm from the bottom 10. If the central portion of the bottom 10 is the convex portion 16, the surface of the cotton cloth 6 can be evenly curved when the cotton cloth 6 is stretched, and the surface of the cotton cloth 6 can be stretched uniformly by the stamp body 3 itself. . However, in the present application, the presence of the convex portion 16 does not matter. Because
If the thickness of the ink occluding portion 5 is made larger than the depth of the inner plate 4, the cotton cloth 6 can be stretched to make it evenly curved.
Reference numeral 5 denotes an ink storage section, which is made of a material such as felt, but may be made of any material as long as it can be impregnated with ink.

Next, as a second embodiment of the inner tray 4, the inner tray 4A is provided with a slit 20 so that it is more easily distorted so that the tension for stretching the cotton cloth 6 can be stored (FIG. 7). . The slit 20 extends from the apex of the curved portion 7 to the outer wall 1
1 and further extending to the collar portion 9, the four sides are separated and independent from the apex of the curved portion 7. Although the middle plate is illustrated in the drawing for a rectangular stamp stand, it may be a circular plate, and at this time, several slits 20 can be provided at equal intervals. Reference numeral 14 denotes a frame-shaped frame body, which is fitted and fixed to the end portion of the bottom container 2 and is provided with a pressing piece 15 on the inside of the bottom container 2 for swingably abutting the collar portion 9. The lower end surface of the pressing piece 15 is an inclined surface 21, and since the inclined surface 21 and the return wall 9B of the collar portion 9 are in contact with each other, the collar portion 9 can be smoothly slid to the outside. There is. Regarding the material, the ink storage section 5 is a synthetic fiber such as polyester, nylon, felt or a natural fiber, and is easily impregnated with ink. Further, the ink storage section 5 may be made of various kinds of synthetic fibers or natural fibers in multiple layers, and the thickness thereof is preferably larger than the depth of the middle plate 4. The cotton cloth 6 is a natural fiber or a synthetic fiber. The lid container 1 and the bottom container 2 are metal forged products and synthetic resin molded products. Also, the frame 1
4 is a synthetic resin molded product. Finally, the inner plate 4 is a hard or soft synthetic resin molded product with a plate thickness of 0.2 mm to 2.0 mm.
mm is preferred.

Next, the assembly of the stamp body 3 and the stamp base will be described in detail. Ink storage part 5 in the inner plate 4
And the cotton cloth 6 is placed so as to cover the surface thereof, and the ends of the cotton cloth 6 and the bottom 9A of the collar portion 9 provided around the inner plate 4 are stretched with the cotton cloth 6 while heat-melting them. I'm wearing it. The heat-sealed portion extends over the entire bottom 9A of the collar 9. At this time, the curved portion 7 formed by the outer wall 11 and the inner wall 12 and the space portion 8 is tilted inward, and the outer wall 11 is expanded outward. In this way, the assembled stamp body 3 is stored in the bottom container 2, and the frame body 14 is fitted and fixed to the end portion of the bottom container 2 from above, and the frame body 14
The pressing piece 15 of (1) presses the return wall 9B of the collar portion 9 downward. Then, the curved portion 7 is set in a distorted state as shown in FIG. 2, and since the cotton cloth 6 is heat-sealed to the bottom 9A and the inclined surface 21 is flat, it is not caught by the cotton cloth 6. . Further, the flange 9 and the bottom container 2 are provided with a free space S that can be moved downward and outward.
Next, when the ink storage part 5 is impregnated with ink and a stamp or the like is used, if the cotton cloth 6 is pressed to apply the ink, the cotton cloth 6 will be stretched due to the settling. With respect to such elongation, the above-mentioned distorted force of the curved portion 7 acts to restore the original force, and absorbs the elongation of the cotton cloth. At this time, the collar portion 9 smoothly moves outward while being pressed against the inclined surface of the pressing piece 15. With such a configuration and the assembling method, the cotton cloth 6 can always be continuously tensioned.

[0009]

[Effects] The present invention having the above-described structure produces the following effects. In the assembled stamp body 3, the end portion of the cotton cloth 6 is heat-sealed to the collar portion 9, and the return wall 9B of the collar portion 9 and the inclined surface of the pressing piece 15 are brought into contact with each other to attach the collar portion 9 to each other. Since it can be swung vertically and horizontally, tension can always be applied to the cotton cloth 6. , It is possible to always apply tension, so that when the ink is impregnated, the wrinkles due to the elongation of the cotton cloth 6 over time and the wrinkles caused by the settling of the cotton cloth 6 due to the use of the stamp are extended, and a uniform ink application is always applied. A clear impression can be obtained. The ink storage part 5 is arranged inside the inner plate 4, and a cotton cloth 6 is stretched so as to cover the surface of the ink storage part 5. While the curved part 7 is distorted, the bottom 9A of the collar part 9 is covered with the cotton cloth. Even if the cotton cloth 6 is stretched by impregnating it with ink because the end portion of 6 is heat-sealed to form the stamp body 3, the stretch is absorbed by the restoring force of the strain. Further, since the stamp body 3 is an integrated product as described above, it is easy to handle and assemble. Since the shape and configuration of parts are simple, the mold is cheap,
The assembling cost can be reduced, and the target cotton cloth 6 can be stretched.
