SELF-INKING STAMP

摘要

A self-inking stamp is configured such that, in a marking preparation state, a marking member is maintained in a state in which it is oriented upwardly within a stamp body of the self-inking stamp and pressed against an ink pad to supply ink thereto, and, during a marking operation, after the inner frame is moved downwardly while being reversingly rotated and oriented downwardly, the downwardly-oriented marking member is exposed from the stamp body and enabled to make a mark. The self-inking stamp is also configured to lock the marking member in a state in which it is exposed from the stamp body, for replacement and cleaning of the marking member.

主权项

1. A self-inking stamp having a marking state in which it can carry out a marking operation, a marking preparation state, and a locked state, and comprising:
an elastic member having a stretched state when the stamp is in the marking preparation state and a compressed state when the stamp is in the marking state and the locked state; an outer frame movable in a downward direction during a marking operation and movable in an upward direction on completion of a marking operation, wherein the outer frame is normally biased in the upward direction by the elastic member; a guide element extending in an upward-downward direction; an inner frame movable inside the outer frame in an upward-downward direction of the outer frame with respect to the outer frame under a bias of the elastic member, while being guided by the guide element, and being pushed out from the outer frame when the stamp is in the marking preparation state, the inner frame having an upper portion fixedly provided with an ink pad oriented downwardly and a lower end formed with a marking opening wherein the elastic member is disposed between an upper portion of the outer frame and the upper portion of the lower frame to bias the inner frame downwardly with respect to the outer frame; a marking member pivotally attached to a lower portion of the outer frame and configured to flip in conjunction with the upward-downward movement of the inner frame with respect to the outer frame wherein the marking member protrudes downwardly from the marking opening of the inner frame when the stamp is in the marking state and is pressed against the ink pad provided on the upper portion of the inner frame when the stamp is in the marking preparation state; locking means for locking a positional relationship between the outer frame and the inner frame, when the stamp is in a locked state in which the inner frame is pushed inside the outer frame against a bias force of the elastic member and the elastic member is compressed, and the marking member is exposed and protrudes downwardly from the marking opening, and for releasing the outer frame and the inner frame from the locked positional relationship to place the stamp in a marking preparation state in which the inner frame is pushed out from the outer frame, the elastic member is stretched, and the marking member is pressed against the ink pad; and an inner-frame cap configured to be detachably attached to the inner frame while capping the marking opening, and pushing the inner frame upwardly with respect to the outer frame to a position where the locking means becomes operative.
