Description

The present invention relates to a stamp that can prevent the occurrence of warpage of a printed body and obtain a clear imprint.

Conventionally, a stamp in a form in which a stamp is stamped by exposing a printed body when the holder is pushed down is known, and is widely used in company-related, school-related, hospital-related, and the like. Such a stamp has a structure having a printed body at the bottom, a main body that freely moves up and down in the cover member, and a cylindrical ink cartridge that is detachably set in the main body. It is possible to stamp for a long period of time by exchanging.
As the ink cartridge, a storage type ink cartridge in which a storage body is filled is generally used.

In such a stamp, the main body is usually made of synthetic resin. For this reason, when used for a long time, there is a phenomenon that only the central part where the stamping load is applied is deformed so as to bend downward, or the resin is deformed over time and warps inward or outward. As a result, there was a problem that the imprint was chipped.

On the other hand, as shown in Patent Document 1, the applicant works by suspending a cylindrical portion from the ceiling of the holder and supporting the outer peripheral wall of the tubular replenishment port of the main body with the inner peripheral wall of the cylindrical portion. The structure that prevents the warp to the outside is disclosed earlier. However, in the stamp described in Patent Document 1, although the warp to the outside of the replenishment port can be prevented, the warp to the inside cannot be prevented, and as a result, the main body is curved and the imprint is chipped. There was a problem that it could not be completely prevented.

Japanese Unexamined Patent Publication No. 8-300788

An object of the present invention is to solve the above-mentioned conventional problems and to provide a stamp capable of preventing the occurrence of warpage of a printed body and obtaining a clear imprint. Further, it is an object of the present invention to provide a stamp capable of appropriately supplying ink not only as an ink cartridge but also as a direct liquid type ink cartridge.

The stamp of the present invention made to solve the above problems has a main body having an occlusion body and a printing body at the lower part, and a cover member for accommodating the main body so as to be able to move up and down.
A pair of left and right struts are projected from the upper surface of the main body, and an elastic member that always urges the main body upward against the cover member is attached to the struts.

The figure which shows the state, (d) is the figure which shows the state which the engagement is completed.

Hereinafter, preferred embodiments of the present invention will be shown with reference to the drawings.
1 is a front view showing a stamp according to the present invention, FIG. 2 is a perspective view, FIG. 3 is a sectional view taken along the line AA of FIG. 2, and FIG. 4 is a sectional view taken along the line BB of FIG.
In the figure, reference numeral 1 is a main body, which has a printing body 2a and a storage body 2b at the lower part. The main body 1 is configured to freely move up and down in the cover member 3. Reference numeral 3a is a pair of doors that open and close in a wing manner, and reference numeral 4 is a holder that covers the main body 1, and a cylindrical ink cartridge 5 is detachably set in the main body 1. The above configuration is basically the same as that of the conventional type of elevating type stamp. Further, the ink cartridge 5 includes both an occlusion type and a direct liquid type.

A pair of left and right columns 6 and 6 are projected from the upper surface of the main body, and the elastic body 7 urges the cover member 3 so that the main body 1 is always pulled upward. (Coil spring in the figure) is attached. The columns 6 are provided opposite to each other on the left and right sides of the top plate 1a of the main body 1, and the columns 6 penetrate the holes 3c of the horizontal partition plate 3b of the cover member 3 and project upward. Further, a bridging member 8 for keeping a constant distance between the pair of columns is attached to the tip of the column. The bridging member 8 will be described later.
Further, an elastic body 7 is mounted on the support column 6, and an elastic force acts so as to constantly widen the space between the horizontal partition plate 3b and the bridging member 8, and as a result, the main body 1 is always pulled up. The printed body 2a is housed in the cover member 3.

The bridging member 8 is attached to the tips of the left and right columns 6 and 6 to maintain a constant distance between the columns. That is, even if a stamping load is applied to the main body 1 or the resin is deformed over time, the columns 6 are prevented from bending either inside or outside by keeping the distance between the columns constant. As a result, the main body 1 is prevented from being deformed in an arc shape.

As shown in FIGS. 5 and 6, the bridging member 8 has an insertion hole 8a for the ink cartridge 5 formed in the center, and the left and right ends are engaged for engaging with the tip of the support column 6. The hole 8b is formed. Further, on the side facing the engaging hole 8b, a claw piece 8c for preventing the support column 6 from being disengaged is formed. The engagement operation between the bridging member 8 and the support column 6 is as follows.

As shown in FIG. 7A, the engaging hole 8b of the bridging member 8 is lowered so as to be close to the tip end portion of the support column 6. Next, when the bridging member 8 is further lowered even after the lower corner portion of the engaging hole 8b comes into contact with the tip end portion of the support column 6, the lower corner portion of the engagement hole 8b becomes the inclined surface 6a of the support column 6. It descends smoothly along (see FIG. 7 (b)). After that, the engaging hole 8b is lowered to a position corresponding to the groove portion 6b of the support column 6. At this time, the claw piece 8c of the bridging member 8 that was pushed by the tip of the support column 6 and was plastically deformed presses the support column 6 (see FIG. 7 (c)). Next, as shown in FIG. 7 (d), the plate portion forming the engaging hole 8b fits into the groove portion 6b of the support column 6, and the claw piece 8c returns to the linear shape. By returning the shape of the claw piece 8c, the fitting between the plate portion forming the engaging hole 8b and the groove portion 6b of the support column 6 is in a fitted and killed state, and the fitting does not come off naturally.

The bridging member 8 also serves as a fixing portion for fixing the upper end of the elastic body 7 mounted on the support column 6. That is, the main body 1 has a structure that freely moves up and down in the cover member 3, and the main body 1 having the printed body 2a is always urged by the elastic body 7 and pulled up, which is contrary to the elasticity at the time of stamping. , The structure is such that the printed body 2a is pushed down. Therefore, although the elastic body 7 for imparting elasticity is attached to the support column 6, the number of parts is increased by allowing the bridging member 8 to also serve as a fixing portion for fixing the upper end of the elastic body 7. It has a simple structure with few and easy assembly procedures. Further, since the support column 6 and the bridging member 8 have a structure of fitting and killing, it is possible to prevent the elastic body 7 from being inadvertently detached from the support column 6.

Further, a hole 8a for inserting an ink cartridge is formed in the central portion of the bridging member 8, and the ink cartridge 5 can be easily attached / detached by simply inserting the ink cartridge 5 into the hole 8a. The set ink cartridge 8 is supported by the hole 8a and does not cause glaring, and has a structure in which a stable mounting state is maintained.
The ink cartridge of the present invention includes both a suction type and a direct liquid type, but since the ink supply port is in close contact with the storage body 2b, stable ink supply is provided for the direct liquid type. It has the advantage of being able to do it.

In the stamp configured as described above, a pair of left and right columns are projected on the upper surface of the main body, and an elastic member that always urges the main body upward is attached to the columns, and a pair of columns are attached to the tip of the columns. Since the structure is equipped with a bridging member to maintain a constant distance between the struts, even if a load is applied to the main body at the time of stamping or the struts try to deform inward or outward due to changes over time, etc. Since the distance between the two is kept constant, the main body is prevented from being deformed and the imprint is not chipped. In addition, the structure is simple, the number of parts is small, the assembly work can be simplified, the ink cartridge can be easily attached and detached, and the ink cartridge can be prevented from glaring. There is also.
