Abstract

A device for securing a turning axle (9) of a type unit (3) to an actuating bow (5) of a self-inking stamp (1) having a turning mechanism (2), with at least one bushing-shaped axle-securing member (12) which, in the mounted position, is slid onto an end region of the turning axle (9) with a bushing body (95) and externally contacts the actuating bow (5) with a radial projection (96), wherein the bushing body (95) includes at least one tongue-like, resiliently radially deflectable snap-in element (98) with a radially inwardly oriented snap-in projection (99) which, in the mounted position, engages in a snap-in depression (101) provided as corresponding snap-in element in the turning axle (9) in the end region of the latter.

Claims

1. A device for securing a turning axle (9) of a type unit (3) to an actuating bow (5) of a self-inking stamp (1) having a turning mechanism (2), with at least one bushing-shaped axle-securing member (12) which, in a mounted position, is slid onto an end region of the turning axle (9) with a bushing body (95) and externally contacts the actuating bow (5) with a radial projection (96), wherein the bushing body (95) includes at least one tongue-like, resiliently radially deflectable snap-in element (98) with a radially inwardly oriented snap-in projection (99) which, in the mounted position, engages in a snap-in depression (101) provided as a corresponding snap-in element in the turning axle (9) in the end region of the latter.

2. The device according to claim 1, wherein the tongue-like snap-in element (98) is provided in a window (100) of the bushing body (95) and, at one end thereof, integrally follows upon the bushing body (95).

3. The device according to claim 2, wherein the snap-in projection (99) is provided on a freely cantilevering end of the tongue-like snap-in element (98).

4. The device according to claim 1, wherein the snap-in depression (101) in the turning axle (9) is formed by an annular groove.

5. The device according to claim 1, wherein the turning axle (9) is made of metal, in particular steel.

6. The device according to claim 1, wherein the bushing body (95) has two diametrically oppositely arranged tongue-like snap-in elements (98).

7. The device according to claim 1, wherein the bushing body (95) is integrally formed.

8. The device according to claim 7, wherein the bushing body (95) with the radial projection (96) and the, or each, snap-in element (98) is an injection-molded member.

9. The device according to claim 1, wherein the axle securing member (12) has an opening (97) extending therethrough for its slipping onto the turning axle (9).

10. The device according to claim 1, wherein the actuating bow (5) has two bow parts (5A, 5B) pushed one into the other, the leg ends of which each having passage openings (94A, 94B) for the turning axle (9), wherein the axle securing member(s) slid onto the turning axle (9) simultaneously hold the legs (13) of the bow parts (5A, 5B) against each other.

11. The device according to claim 1, wherein a freely cantilevering end of the tongue-like snap-in elements (98) in the operating position is the outer end of the snap-in element, whereas the tongue-like snap-in element at the further inwardly located end merges integrally with the remaining bushing body (95).
