Abstract

An axial securing device (19) for an end of a pivot axle (6) of a hand stamp (1) comprising a self-inking device, wherein the pivot axle (6) extends through a character unit (3) accommodated in a stamp housing (2) as well as through guiding slots (12) in side walls (7, 8) of the stamp housing (2), the ends of the pivot axle being held in openings (15) in legs (13, 14) of an actuating bow (5), which actuating bow is movable relative to the stamp housing (2), the axial securing device (19) comprising an annular member (17) capable of being snapped onto the end of the pivot axle (6), which annular member comprises at least one radially inward snap projection (20) for snapping engagementin a peripheral groove (21) adjacent the outer end of the pivot axle (6); to facilitate its manufacture, the annular member (17) is formed to be integral with a bearing sleeve (16) which, with the axial securing device (19) mounted, extends through the actuating bow leg (13) as well as through the longitudinal slot (12) in the side wall (7) of the stamp housing (2).

Claims

1. An axial securing device (19) for an end of a pivot axle (6) of a hand stamp (1) comprising a self-inking device, wherein the pivot axle (6) extends through a character unit (3) accommodated in a stamp housing (2) as well as through guiding slots (12) in the side walls (7, 8) of the stamp housing (2), the ends of the pivot axle being held in openings (15) in legs (13, 14) of an actuating bow (5), which actuating bow is movable relative to the stamp housing (2), the axial securing device (19) comprising an annular member (17) capable of being snapped onto the end of the pivot axle (6), which annular member comprises at least one radially inward snap projection (20) for snapping engagement in a peripheral groove (21) adjacent the outer end of the pivot axle (6), characterized in that the annular member (17) is formed to be integral with a bearing sleeve (16) which, with the axial securing device (19) mounted, extends through the actuating bow leg (13) as well as through the longitudinal slot (12) in the side wall (7) of the stamp housing (2).

2. An axial securing device according to claim 1, characterized in that the annular member (17) is formed by several annular segments (17a-17d) projecting from the front end of the bearing sleeve (16) and separated from each other by slots (18a-18d).

3. An axial securing device according to claim 2, characterized in that four annular segments—

(—

17a-17d) are provided, each corresponding approximately to a quarter circular arc seen in front end view, separated from each other by slots (18a-18d) extending perpendicular relative to each other.

4. An axial securing device according to claim 1, characterized in that the annular member (17) and the bearing sleeve (16) together are injection-molded of plastics.

5. A hand stamp (1) comprising at least one axial securing device (19) according to claim 1, characterized in that on a guiding part (24) guiding the legs (13, 14) of the actuating bow (5) and attached on the stamp housing (2), at least one lug plate (26, 27) is molded which extends as a spacer element into the gap between the stamp housing (2) and the respective actuating bow leg (13).
