DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(10) FIGS. 1 to 3 show a plate support 1 according to the invention for a self-inking stamp 2 (cf. FIG. 4). The plate support 1 has a print side 3 for attaching a text plate (not shown) to the plate support 1. The plate support 1 has two journals 5, 6 defining a swiveling axis 7 of the plate support 1. The journals 5, 6 are integrally formed with the plate support 1. When used in a self-inking stamp 2, the plate support 1 is mounted to swivel about the swiveling axis 7 (cf. FIG. 6).

(11) The plate support 1 furthermore comprises a reinforcing axle 8. In the represented embodiment, the reinforcing axle 8 penetrates the two journals 5, 6 completely and flushes at both ends with the ends of the respective journals 5, 6. A central part 9 of the reinforcing axle 8 is accessible and visible between the journals 5, 6 from a back side 10 of the plate support 1, the back side 10 being opposite the print side 3 (cf. FIG. 2). The reinforcing axle 8 in this example consists of steel, and the rest of the plate support of POM. The shape of the reinforcing axle 8 essentially corresponds to a cylindrical bar. The journals 5, 6 enclose the ends of the reinforcing axle 8 like cylindrical tubes.

(12) For better distributing the force transmitted during the printing of the stamp, the plate support 1 has a frame 11 surrounding the circumference, and longitudinal bracings 12 and transverse bracings 13 at the back side 10.

(13) FIGS. 5 to 8 show a self-inking stamp 2 according to the invention with a housing 14 and an actuating part 15 in the form of an actuating bow. The actuating part 15 is shiftable with respect to the housing 14 along an axis of translation 16 (cf. FIG. 6). A plate support 1 according to FIG. 1 is coupled with the actuating part 15 by the journals 5, 6 being received in corresponding bearing recesses at the inner side of the actuating part 15 (cf. FIG. 4).

(14) The housing 14 comprises, in two opposite side walls 17, 18, one guiding slot 19 each for receiving the journals 5, 6 of the plate support 1. At the outer side of the two side walls 17, 18, two guide rails 20 each for guiding the actuating part 15 are provided. The guide rails 20 are arranged along or in parallel with the axis of translation 16.

(15) Each one of the four guide rails 20 comprises a profile section 21 in an upper region of a half of the guide rail 20, the half facing the actuating part 15. In the region of this profile section 21, the guide rail 20 has an L-shaped profile in a plane transverse to the direction of translation 16 (cf. FIGS. 7 and 8). The L-shaped profile forms a groove between a first leg 22 and a second leg 23, the first leg 22 being arranged in parallel to the swiveling axis 7 of the plate support 1, and the second leg 23 being arranged transverse to the swiveling axis 7 of the plate support 1. Between the legs 22, 23, a groove is formed which is arranged in the direction transverse to the swiveling axis 7 of the plate support 1.

(16) The actuating part 15 comprises, at its inner side, four bearing bushes 24 each corresponding to the profile section 21 of a guide rail 20. Each one of the bearing bushes 24 also has an L-shaped bush profile in a plane transverse to the direction of translation 16 which profile corresponds to the assigned groove (cf. FIGS. 7 and 8). The bush profile comprises, just as the groove, a first leg 25 and a second leg 26 which are arranged in parallel or transverse to the swiveling axis 7 of the plate support 1.

(17) In the rest position of the self-inking stamp represented in FIGS. 4 to 8, the bearing bushes 24 of the actuating part 15 are each engaged with a profile section 21 of the guide rails 20 at the housing 14. To be more precise, the second legs 23, 26 of the L-shaped profiles are engaged in this position (cf. FIG. 8). This position corresponds to a blocking position, i.e. the side walls of the actuating part 15 are blocked with respect to the side walls 17, 18 of the housing 14 against a movement parallel to the swiveling axis 7 of the plate support 1. The self-inking stamp 2 cannot be bent open in this position.
