ABSTRACT:
BACKGROUND OF THE INVENTION
(1) Field of the Invention
The present invention relates to a stamping implement including a stamping element made up of a porous stamp compound having continuous pores and an ink retainer for supplying the stamping element with ink.
(2) Description of the Prior Art
Conventionally, a stamping implement called an impregnation stamp which uses a porous stamp compound having continuous pores capable of retaining ink such as sponge rubber etc., and hence does not need application of ink when stamped has been well known.
A stamping implement of this type has a detachable cap for protection of stamping face, hence the operator needs tedious handling of removal and attachment of the cap for every stamping and suffers the problem of their hands being smudged with ink from unintentional touch when the cap is removed and attached and also the losing of the removed cap.
In order to eliminate these problems, a stamping implement with an incorporated lid has been disclosed in the registered publication of Japanese Utility Model No. 2519833, devised by the present applicant. However, this configuration still needs a tedious operation of opening and closing the lid and also may have drawback of the material of the lid being damaged because the lid deforms every time it is opened. There also exists a stamping implement having a rotary lid in order to allow for smooth lid opening and closing. However, this configuration suffers from complicated lid assembly. Further, when the stamping implement is hand-carried, the lid may be opened unintentionally leading to ink smudge or leading to the drawback of the stamping face being damaged or dirtied with dust. Moreover, when the stamping element needs to be replenished with ink or the stamping unit as a whole needs to be replaced, the lid may be the obstacle that makes these operations difficult.
Stamping implements of this type may need the ink retainer to be replenished with ink. Further, the stamping element needs to be exchanged with another one having a different stamping face of characters. However, conventional stamping implements have needed the tedious work of removing the stamping element and/or ink retainer from the barrel body and hence there has been discontent because of the difficulties in performing these tasks.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to solve the above problems or to provide a stamping implement which offers advantage of allowing its lid to be automatically opened or closed by only vertical movement of the outer cylinder relative to the inner cylinder when stamping, which is free from the problem of the lid being deformed and damaged when it is opened, and which disallows the lid to be unintentionally opened when it is hand-carried and hence prevents ink smudging and the stamping face from being damaged or dirtied due to the unintentional lid opening.
It is another object of the present invention to provide a stamping implement which allows the lid to be locked in the opened state so that the operator can easily refill the stamping element with ink and replace the stamp unit as a whole with another unit.
It is a further object of the present invention to provide a stamping implement with an openable/closable lid in which the thin-walled, delicate shield portion can be reinforced and shaped so as not to be damaged while it still has a good appearance and offers easy lid assembly.
It is still another object of the present invention to provide a stamping implement with an automatic openable/closable lid which has a rotary configuration in order to allow smooth opening and closing and still offers easy lid assembly.
It is a still further object of the present invention to provide a stamping implement which allows the stamping unit to be easily removed from the barrel body in order to facilitate easy ink refill to the ink retainer and easy replacement of a stamping element.
In order to achieve the above object, the present invention is configured as follows:
In accordance with the first aspect of the present invention, a stamping implement includes:
a stamp unit having a stamping element made up of a porous stamp compound having continuous pores at the lower end thereof;
an outer cylinder having an opening at the lower end thereof, a cutout portion on the side thereof and the stamp unit fixed therein;
an inner cylinder having an opening at the lower end thereof a window hole on the side thereof and being arranged outside the stamp unit and inside the outer cylinder with the lower end thereof projected out below the lower end of the outer cylinder so as to be slidable in the vertical direction relative to the outer cylinder; and
a lid configured of an arm portion pivoted at an axial support near the upper end thereof and a shield portion at the lower end of the arm portion, and is characterized in that the axial support of the lid is axially supported so as to be rotatable by a frame of the window hole of the inner cylinder, and the lid rotates in linkage with the vertical movement of the inner cylinder relative to the outer cylinder, whereby the lower face of the stamping element is shielded when the lid is closed while the lower face of the stamping element is capable of being released when the lid is open.
In accordance with the second aspect of the present invention, the stamping implement having the above first feature further comprises: a supporting cylinder opening at both upper and lower ends disposed inside the outer cylinder; a middle cylinder for a stamp unit removably fitted through the supporting cylinder, the upper end of the middle cylinder being projected above the upper end of the supporting cylinder; and a removable cap attached to the upper end of the outer cylinder.
In accordance with the third aspect of the present invention, the stamping implement having the above first feature further comprises: a U-shaped groove for receiving the axial support of the lid, formed in the frame of the window hole of the inner cylinder; and a cover portion disposed over the frame of the cutout portion of the outer cylinder so as to cover the outside of the U-shaped groove for preventing the axial support from coming off.
In accordance with the fourth aspect of the present invention, the stamping implement having the above first feature is characterized in that a presser portion which abuts and presses the foot piece of the lid in the lid's opening direction when the outer cylinder moves down is provided on the side surface of the supporting cylinder.
In accordance with the fifth aspect of the present invention, the stamping implement having the above first feature is characterized in that side-walls having a projected ridgeline portion are formed around the connection between the shield portion and arm portion of the lid; and the inner cylinder is formed with a depressed ridgeline portion which mates in substantially tight contact with the projected ridgeline portion formed on the lid.
In accordance with the sixth aspect of the present invention, the stamping implement having the above first feature further comprises a locking mechanism between the inner cylinder and outer cylinder for stopping the vertical movement of the inner cylinder relative to the outer cylinder when the lid is open and when the lid is closed.
In accordance with the seventh aspect of the present invention, the stamping implement having the above sixth feature is characterized in that the locking mechanism comprises: a partitioning wall formed on the inner periphery of the inner cylinder; and a locking cylinder disposed in the upper part of the outer cylinder so as to be rotatable within an appropriate range relative to the outer cylinder, and the partitioning wall becomes engaged with the locking cylinder when the locking cylinder is rotated in the lid open or closed state, so that the vertical movement of the inner cylinder relative to the outer cylinder is prohibited.
According to the present invention thus configured, it is possible to provide a stamping implement having a sta
