Abstract

A method for manufacturing a plate support for a self-inking stamp and plate support with a print side for attaching a text plate to the plate support, with two journals defining a swiveling axis of the plate support about which swiveling axis the plate support is mounted to swivel when used in a self-inking stamp, and with a reinforcing axle at least partially penetrating the two journals, integrally forms the journals with the plate support.

Claims

1. A plate support for a self-inking stamp comprising:

(a) a plate support body having a print side for attaching a text plate on the plate support body;

(b) first and second journals integrally formed with the plate support body and defining a swiveling axis; and

(c) a reinforcing axle at least partially penetrating the first and second journals;

wherein the plate support body is mounted to swivel about the swiveling axis when used in the self-inking stamp.

2. The plate support according to claim 1, wherein the reinforcing axle completely penetrates the journals.

3. The plate support according to claim 2, wherein the reinforcing axle has ends flush with ends of the first and second journals, respectively.

4. The plate support according to claim 1, wherein a central part of the reinforcing axle between the first and second journals is accessible from a back side of the plate support body, the back side being opposite the print side.

5. The plate support according to claim 4, wherein the central part is visible from the back side.

6. The plate support according to claim 1, wherein the reinforcing axle is made of metal.

7. The plate support according to claim 6, wherein the reinforcing axle is made of steel.

8. A self-inking stamp comprising:

(a) a housing;

(b) an actuating part shiftable with respect to the housing along an axis of translation; and

(c) a plate support coupled with the actuating part;

wherein the plate support comprises a plate support body having a print side for attaching a text plate on the plate support body, first and second journals integrally formed with the plate support body and defining a swiveling axis, and a reinforcing axle at least partially penetrating the first and second journals;

wherein the plate support body is mounted to swivel about the swiveling axis;

wherein the housing comprises one guiding slot each in opposite first and second side walls, respectively, for receiving the first and second journals of the plate support;

wherein at least one guide rail is provided at at least one of the first and second side walls for guiding the actuating part along the axis of translation;

wherein at least one profile section of the at least one guide rail and a bearing bush corresponding to the at least one profile section at the actuating part are formed such that the bearing bush is engaged with the at least one guide rail in the at least one profile section in a blocking position such that the bearing bush is blocked against a movement parallel to the swiveling axis of the plate support.

9. The self-inking stamp according to claim 8, wherein the at least one guide rail comprises, in a region of the at least one profile section, an oblong indentation formed in a direction transverse to the swiveling axis of the plate support, and wherein the bearing bush comprises a bush profile corresponding to the indentation.

10. The self-inking stamp according to claim 9, wherein the oblong indentation comprises a groove.

11. Self-inking stamp according to claim 9, wherein the at least one guide rail in the at least one profile section has a guide rail profile comprising first and second guide rail legs, wherein the bearing bush has a bearing bush profile corresponding to the guide rail profile comprising first and second bearing bush legs, wherein the first guide rail leg and the first bearing bush leg are parallel to the swiveling axis of the plate support, and wherein the second guide rail leg and the second bearing bush leg are transverse to the swiveling axis of the plate support and are engaged in the blocking position.

12. The self-inking stamp according to claim 8, wherein the at least one guide rail has a first half facing the actuating part and a second half and wherein the at least one profile section of the at least one guide rail extends only in the first half of the at least one guide rail.

13. A method for manufacturing a plate support for a self-inking stamp, the method comprising:

(a) designing a cavity of a mold for integral manufacture of first and second journals with a plate support body of the plate support; and

(b) manufacturing the plate support by an injection molding process in the mold;

wherein the mold comprises a core in a region of the first and second journals.

14. The method according to claim 13, wherein the core is removed after the injection molding process and replaced by a reinforcing axle.

15. The method according to claim 13, wherein the core is formed by a reinforcing axle and wherein the reinforcing axle remains in the plate support after the injection molding process.
