DETAILED DESCRIPTION OF EMBODIMENTS

(10) FIGS. 1 to 6 show a stamp 1, in particular a so-called self-inking stamp 1, comprising at least a stamping component, in particular a top part 2 and a bottom part 3, and a stamping insert 4, wherein in the bottom part 3 a cushion-receiving element 5 to accommodate an ink cartridge 6 is formed. The stamping insert 4 is connected via a reversing mechanism 7, which preferably comprises a slide track 8, in the bottom part 3 with the top part 4 so as to move synchronously. Here the stamping insert 3 is mounted via an axle 9 extending through the stamping insert 4. For the sake of completeness, it is mentioned that trunnions or two axle elements can alternatively be used if the stamping insert 4 is suitably designed. It is essential that the axle 10 or the trunnions or axle elements must protrude from the stamping insert 4 through the slide track 8 into the top part 2 in order to be coupled to the top part 2 there.

(11) In a resting position 10 according to FIG. 1, a text plate and/or an MB unit (mounted band unit) (not shown) mounted on the stamping insert 3 butts against the ink cartridge with ink pad (6) soaked with stamping ink in the cushion-receiving element 5, so that in this position ink is absorbed from the ink cartridge 6. In a stamping process for producing a stamp impression, in a stamp position the stamping insert 3 with the text plate and/or the MB unit is moved into a stamping position via the reversing mechanism 7, whereby to this end the top part 2 is pushed over the bottom part 3 and the stamping insert 4 is rotated so that a spring element (not shown) arranged between the two elements is compressed, whereby subsequent automatic return to the resting position 10 is ensured. A detailed description of the reversing mechanism 7 and the combination of the stamp components, in particular the top part 2 over the bottom part 3, is omitted, as this has been disclosed innumerable times in so-called self-inking stamps 1 from the prior art. Also, a different type of reversing mechanism 7 than shown can be used, or alternatively a moving slide track 8 can be used to create a stamp impression.

(12) Furthermore, it is pointed out that the solution according to the disclosed embodiments is not limited to the stamp shape shownrectangularbut can also be applied to other shapes of stamp 1, such as, for example, square, elliptical, trapezoidal.

(13) The present disclosure now envisions that an axle bearing element 11 is inserted or positioned, respectively, to couple the stamping insert 4 to the top part 2. This has the advantage that the axle bearing element for mounting and guidance is made of a material adapted for this purpose, in particular plastic, which may differ from the material of the top part 2 and/or bottom part 3.

(14) Advantageously, a material having good sliding properties is used, so that a stamping operation can be carried out with low friction losses on the axle bearing. The adaptation of the material to the required properties will also increase the stamping comfort.

(15) Here, the axle bearing element 11 has a base body 12 in which an elongated hole 13 or an elongated hole recess 13 is arranged for receiving and guiding the axle 10: the elongated hole 13 or the elongated hole recess 13 extends horizontally in the slide track 8 in order to support the movement of the axle 10 during a stamping operation. Furthermore, at least one but preferably two latching elements 14 are arranged on the base body 12, which have a latching hook 15. In the exemplary embodiment shown, the latching elements 14 are concomitantly designed as guide elements 16 for introduction in guide webs 17 in the top part 2.

(16) Furthermore, the axle bearing element 11 has an angularly extending insertion surface 18 which supports insertion of the axle 10 into the elongated hole 13 or elongated hole recess 13, respectively, i.e. the angular course is designed in such a way that it extends from the elongated hole 13 or elongated hole recess 13, respectively, in the direction of the lower edge 19 of the base body 12, so that in the region of the lower edge 19 there is a smaller material thickness than in the region of the elongated hole 13 or elongated hole recess 13. The insertion surface 18 is this arranged at the opposite side of the base body 12 with the integrally formed latching elements 14.

(17) Furthermore, on the side opposite of the insertion surface 18, a locking head 21 formed via an elastically deformable connecting web 20 is connected to the base body 12. Here, the connecting web 20 between the two guide elements 16 of the latching elements 14 is integrally formed on the base body 12, resulting in a one-piece component that can be installed in the top part 2 in one working step. Here the locking head 21 can have an actuating element 22 that projects through a locking head opening 23 in the top part 2.

(18) In order for the axle bearing element 11 to be mounted in the top part 2, the top part 2 has corresponding guide webs 17 into which the guide elements 16 of the latching elements 14 are inserted. Furthermore, guide webs 17 are provided with corresponding latching elements, in particular a latching edge 24, on which the latching hook 15 can engage, as can be seen in FIGS. 5 and 6; the guide webs 17 are arranged on the side faces 25 of the top part 2 on the side associated with the inner space 26. The axle bearing element 11 is inserted from below into the guide webs 17 and latches with the latching edge 24 on the guide web 17 so that it can no longer be separated from the top part 2 without applying appropriate force. Then the top part 2 is positioned over the bottom part 3, and the stamping insert 3 with the inserted axle 9 or trunnions is pushed through the slide track 8, whereupon the axle 9 is positioned at the insertion surface 18. By applying appropriate pressure to the stamping insert 3, the axle 9 is pressed onto the insertion surface 18, whereupon the side faces 25 are pressed slightly outwards until the axle 9 snaps or engages, respectively, into the elongated hole 13 or the elongated hole recess 13, so that the side surfaces 25 in turn return to their original position and the stamping insert 3 is mounted.

(19) Concomitantly, when the axle bearing element 11 is inserted, the locking head 21 is slightly deformed, so that when during pushing in it is pushed along the inner surface of the side faces 25 until it engages or snaps, respectively, into the locking head opening 23, i.e. during assembly the locking head 21 is pressed slightly backwards by the flexible connecting web 20, whereby upon reaching the end position of the axle bearing element 11, in particular when the locking head 21 or the actuating element 22 of the locking head 21 coincides with the locking head opening 23, the latter pivots back into the original position and thus projects outwards through the locking head opening 23.

(20) In addition, individual features or feature combinations from the various exemplary embodiments shown and described can inherently form independent inventive solutions or solutions according to the present disclosure.
