Abstract: A self-inking stamp with a stamp pad disposed in a container movably retained in a shaft in the frame of the stamp. To prevent the insertion into the shaft of non-genuine stamp pads the shaft and container are respectively provided with complementary keying features. In a preferred embodiment the keying feature consists of matching grooves and protrusions in the shaft and container, respectively.

Abstract: Top-dyeing self-inking stamp with a bottom section (1) to be placed on a surface to be stamped, an ink pad arranged in a container (3) insertable for replacement into a receiving shaft (8), a flipping mechanism for a stamp platen arranged in the bottom section for reciprocal pivoting movement between the ink pad and a support frame (5) and an actuator upper section (6), the ink pad container being provided at its upper surface with at least one groove (7) extending in the insertion direction for from-fitting engagement by a rib (9) arrange at the upper surface of the receiving shaft.

Abstract: A manually actuable stamp provided with first and second housing sections, one section being provided with stamping platen movable into engagement with a bulging surface and provided with a stamping surface conforming to the bulging surface when in engagement therewith, one of the first and second sections being provided with a continuous rib conforming to the contour of the bulging surface to prevent lateral slippage of the stamp thereon.

Abstract: A device for an holding office utensil, such as an ink stamp, a self-inking stamp or other office utensil, includes a base plate including an arrangement of through holes and a spacer for supporting the base plate in a tilted position on a surface. An attachment is removably insertable in at least one of the through holes and is adapted for holding the office utensil.

Abstract: A stamping device with top inking has a frame (6) that receives a stamp (3) guided in lateral parts (6') of the frame and capable of being moved by a pivoting mechanism (5,7,8) between an ink-receiving position in which the stamp is in contact with an inking pad (2) and a printing position by means of a U-shaped actuator bow (21) coupled to the stamp and capable of being moved by hand with respect to the frame against the force of a spring. The frame that contains the stamp and the reversing mechanism (4) is mounted in a substantially parallelepiped outer housing (1) made of plastic. Both lateral parts of the outer housing (1) have slots (24) for the legs (21') of the frame and cavities (15) for compression springs (16) or the legs (21') of the actuating bow that in turn is mounted in an outer frame (22) made of plastic and provided with lateral parts (22') that also extend into both compression spring-receiving cavities (15).
