Description

Self-inking stamp with removable turning axis

The invention relates to a self-inking stamp with a lower part, an actuating part and a stamp unit, wherein the actuating part is connected to the lower part and is displaceable relative to the lower part, wherein the stamp unit is arranged in the lower part and is pivotably coupled to the actuating part via a turning axis, wherein the turning axis is mounted in the stamp unit so as to be removable in the longitudinal direction of the axis, wherein a securing element is arranged in the lower part, wherein the securing element limits a displacement of the turning axis in the longitudinal direction of the axis.

The invention also relates to a method for removing a turning axis from such a self-inking stamp.

Self-inking stamps with a stamp unit in a stamp base that can be pivoted about a turning axis are known. The pivoting stamp unit can thus be transferred from an inking position, in which a cliché is inked to produce a stamp impression, to an impression position, in which the stamp impression is actually produced with the inked cliché. In order to be able to replace the stamp unit mounted on the turning axis, for example a type unit or a stamp plate, if necessary, it is also known to design the self-inking stamp so that the turning axis can be removed from the stamp unit.

AT 521730 A1 relates to a turning device for a self-inking stamp, into which a turning axis can be inserted from the outside in the longitudinal direction of the axis. The turning axis is secured against movement in the longitudinal direction of the turning axis by means of a locking or snap connection in conjunction with an annular groove provided on the turning axis.

WO 2006/079130 A1 relates to a device for securing a turning axis by means of a locking connection produced via a bushing body pushed onto the turning axis.

AT 517322 Al and WO 2016/ 197171 A2 disclose a hand- stamp with a removable impression unit. If a stamp component is positioned accordingly in a change position, a turning axis can be pushed in and out of the impression unit from the outside through an axis change opening. The axis change opening is closed with a closure cap. The disadvantage here is that the turning axis can get caught on the closure cap or on the edge of the axis change opening, which is closed by the closure cap.

The CN 108819514 shows a stamp with a memory chip that stores a cryptographic certificate.

The object of the invention is to create a self-inking stamp and a method for removing a turning axis from such a self-inking stamp of the type mentioned at the beginning, which avoid or at least reduce at least some of the disadvantages mentioned. In particular, the reliability of the self-inking stamp when producing a stamp impression should be increased and the stamp unit should be reliably accommodated in the lower part of the self-inking stamp. Any movement of the turning axis required during a stamping process should not cause any disturbing noises. In addition, the stamp unit should be easy to replace without special tools.

For this purpose, the invention provides a self-inking stamp as defined in claim 1 and a method as defined in claim 11. Advantageous embodiments and further developments are specified in the dependent claims.

The object is achieved according to the invention by a self-inking stamp, wherein the securing element forms a sliding surface for the turning axis, wherein the sliding surface extends over the entire working area of the turning axis. The self-inking stamp thus has a lower part, an actuating part, for example with a handle, and a stamping unit. The lower part has, for example, a base surface with which the lower part is placed on a substrate to be printed, or is connected to the base surface. The actuating part is connected to the lower part and slidable relative to the lower part. The stamp unit is arranged in the lower part and is pivotably coupled to the actuating part via a turning axis. The stamp unit has a cliché, i.e. a stamp plate or type assembly, with the information to be reproduced during stamping. Thus, by pressing the actuating part down in relation to the lower part placed on a substrate to be printed, in the direction of the substrate, the stamp unit can be pressed from a rest position against the substrate to be printed, thereby creating the stamp impression. For this purpose, the stamp unit is turned around the turning axis during the movement towards the substrate. In order to be able to easily remove the stamp unit from the self-inking stamp, in particular from the lower part, the turning axis is mounted in the stamp unit so that it can be removed along the axis. The turning axis can be mounted in the stamping unit with a slight amount of play so that the turning axis can slide out of the stamping unit when the stamping unit is dismantled, for example due to gravity, or it can be inserted into the stamping unit with friction. To securely hold the turning axis, a locking element is arranged in the lower part, which limits displacement of the turning axis relative to the lower part in the direction of the longitudinal axis of the turning axis, i.e. in the longitudinal direction of the axis. The locking element thus secures the turning axis against undesirable axial advance. The term "axial" in this disclosure refers to the longitudinal axis direction of the turning axis. So that the turning axis is always securely held and can be transferred between its end positions as quietly as possible during a stamping process, the securing element forms a sliding surface for the turning axis, with the sliding surface extending over the entire working area of the turning axis. The working area of the turning axis is the sum of all positions that one end of the turning axis covers between an inking position of the stamping unit and an impression position of the stamping unit. In the inking position, the stamping unit is arranged essentially in an upper position in the lower part, in particular the stamping unit rests against an ink pad and/or the turning axis is arranged in the highest position that can be occupied. In contrast, in the impression position, the stamping unit is arranged essentially in a lower position in the lower part. in particular, the stamp unit rests on a surface to be printed on and/or the turning axis is arranged in the lowest possible position. The sliding surface in particular forms a smooth abutment surface which is free of bumps or steps on which the turning axis could get caught or which could generate noise when the turning axis slides on the securing element, in particular on the sliding surface. It should be noted that, within the scope of the invention, the smooth abutment surface can have slight bumps to an extent which does not impair the function of the smooth abutment surface. The turning axis preferably rests on the sliding surface at least with one of its ends. Viewed from outside the self-inking stamp in the longitudinal direction of the axis, the securing element can thus cover the turning axis. The turning axis is preferably made of metal, in particular a steel axis. The securing element is preferably made of plastic.

Because of the securing element, no annular groove in the turning axis and no locking or snap connection engaging therein, by means of which the turning axis is secured against undesired displacement in the longitudinal direction of the axis, is required. The turning axis is therefore preferably free of an annular groove and a locking or snap connection engaging therein. In addition, no closure cap is required for an axis change opening on which the turning axis could get caught.

When reference is made in this description to location and direction information, these details are to be understood in a position of use in which the stamp is placed on a horizontally arranged base to be printed on. In particular, the term "top" refers to a position close to an actuating part, for example close to a handle of the stamp, and "bottom" refers to a position close to a floor contact surface of the stamp. The term "vertical" means in the direction of gravity. Of course, the stamp can also be used in other positions, in which case the location and direction information must be transferred accordingly.

According to a preferred embodiment of the invention, the securing element is a one-piece, relative to the base lower part movable sliding element. The one-piece design of the sliding element facilitates the production of a smooth sliding surface on which the turning axis can glide as quietly as possible and does not get stuck. The mobility of the sliding element relative to the lower part and thus relative to the turning axis when the latter is stationary, enables the sliding element to be brought into a position in which it no longer covers the turning axis when viewed in the longitudinal direction of the axis. The mobility of the sliding element relative to the lower part thus enables access to the turning axis and therefore release of the turning axis.

If the sliding element is mounted so that it can move in the lower part, in particular so that it can move parallel to the direction in which the operating part is actuated, the sliding element designed as a slider element can enable access to the turning axis, in particular to a now exposed end of the turning axis, from outside the self-inking stamp by moving the sliding element, in particular parallel to the direction in which the operating part is actuated. In particular, the turning axis can be pulled out of or pushed out of the stamp unit. Such a movable arrangement of the sliding element in the lower part also enables the sliding element to be accommodated in the lower part in a space-saving manner. For example, the sliding element can be mounted so that it can move upwards in the lower part, i.e. away from the substrate to be printed on. For the displaceable mounting of the sliding element, the lower part or a component of the self-inking stamp connected to the lower part, in particular inserted into the lower part, can have a guide in which the sliding element is displaceably received.

If the sliding element is pivotably mounted in the lower part, the sliding element can, by pivoting about a pivot axis relative to the lower part, enable access from outside the self-inking stamp to the turning axis, in particular to a now exposed end of the turning axis. Such a pivotable arrangement of the sliding element in the lower part is advantageous, for example, if there is not enough space available for moving the sliding element in the lower part. There is also the possibility of a pivotable mounting of the sliding element. elements, there is a slightly lower risk of the sliding element jamming compared to a sliding bearing. The pivot axis can be mounted on the lower part or on a component of the self-inking stamp that is connected to the lower part, in particular one that is inserted into the lower part.

Advantageously, the securing element, in particular the movable sliding element, can be arranged between an outer covering of one side of the lower part and the stamping unit. It is advantageous if the outer covering has a recess or a through opening for access to the sliding element.

It is particularly advantageous if the sliding element has a first locking position in the lower part, wherein in the first locking position the turning axis is released for removal from the stamp unit. This makes it easy to access the turning axis, in particular an exposed end of the turning axis, from outside the self-inking stamp when the sliding element is arranged in the first locking position in the lower part. The first locking position is therefore a release position for the sliding element or the securing element. This means that in the first locking position the turning axis can be pulled or pushed out of the stamp unit easily and without special tools. The design as a locking position enables the sliding element or the securing element to be reliably locked into this locking position and thus held firmly, and to avoid undesired, in particular automatic, exit from this locking position, for example caused by impacts or vibrations.

It is also advantageous if the sliding element has a second locking position in the lower part, whereby the turning axis is secured in the lower part in the second locking position. The turning axis is thus secured in the second locking position against being pulled out or pushed out of the stamp unit from outside the self-inking stamp and against undesirable axial displacement in the longitudinal direction of the axis. The second locking position is thus a securing position for the sliding element or the securing element. The design as a locking position enables light, to reliably engage the sliding element or the securing element in this locking position and thus hold it firmly, and to avoid undesirable, in particular automatic, exit from this locking position, for example caused by impacts or vibrations.

To form the first locking position and/or the second locking position, the sliding element or the securing element can preferably have first locking elements which can interact with complementary second locking elements in or on the lower part or a component of the self-inking stamp connected thereto. For this purpose, at least one of the first or second locking elements is preferably arranged resiliently. For example, the sliding element can have at least one locking recess, such as a locking notch, as the first locking element, into which locking recess at least one locking projection can engage as the second locking element. Likewise, the sliding element can have at least one locking projection as the first locking element, which locking projection can engage in at least one locking recess as the second locking element.

In order to be able to produce the sliding element or the securing element simply and inexpensively, it is advantageous if the at least one second locking element is spring-loaded on the lower part or spring-loaded to the lower part. For example, the at least one second locking element is arranged on a spring-loaded arm of an insert part, which insert part can be inserted into the lower part of the self-inking stamp and forms, for example, a circumferential frame on the bottom of the self-inking stamp. Preferably, two spring-loaded arms can be provided for locking the sliding element, one on each side of the sliding element, which are in particular tongue-shaped insertion elements protruding upwards from the bottom frame, with which the frame is positioned in the lower part.

The securing element, in particular the sliding element, can preferably be transferred between a release position and a securing position. The release position can be a first locking position in the lower part and/or the securing position sition can be a second locking position in the lower part. In the release position, access from outside the self-inking stamp to at least one end of the turning axis can be enabled and in the securing position, access from outside the self-inking stamp to at least one end of the turning axis can be prevented or at least made more difficult. In particular, the end of the turning axis facing the securing element or sliding element is covered by the securing element or sliding element in the securing position and can rest against it.

Furthermore, it can be provided that the sliding element has a stop for actuating the sliding element, in particular a depression or notch accessible from outside the lower part. In order to actuate the sliding element, the stop can thus be engaged from outside the self-inking stamp or the stop can generally be grasped. The stop is preferably indented or curved inwards with respect to an outer surface of the sliding element, i.e. in the direction of the interior of the self-inking stamp, in order not to hinder movement of the sliding element relative to the lower part by an outwardly projecting stop. It is particularly advantageous if the stop has a sufficiently large engagement surface to be able to engage with a paper clip or the tip of a ballpoint pen and therefore to be able to actuate the sliding element.

If the security element is designed as a removable cover, access to the turning axis, in particular to one end of the turning axis, can be made possible from outside the self-inking stamp by removing the cover. In addition, the cover can be easily replaced in the event of damage. If, however, the removable cover is connected to the self-inking stamp, in particular to the lower part, via a connecting element, for example a band, even when removed, the cover cannot be accidentally lost. The cover can, for example, be plugged onto the lower part or onto a component of the self-inking stamp inserted into the lower part, or pushed into it. The cover can also be designed as a covering element for a side surface of the lower part. The removable cover can therefore protect the functionality. function of a closure cap, however, in contrast to the closure cap according to the document AT 517322 A1 cited at the beginning, it extends over the entire working area of the turning axis and, for example, over the entire height of the side surface of the lower part.

It is also advantageous if a securing element is provided on both sides of the lower part. The securing elements are preferably identical. In this way, after removing the securing elements from the ends of the turning axis, the turning axis is accessible from both sides of the lower part. The turning axis can then be removed particularly easily by pushing the turning axis from one side and pulling the turning axis from the other side of the lower part. For example, to push the turning axis, a pointed object can be pressed against one end of the turning axis and/or to pull and remove it, the turning axis can be grasped at the other end with a gripping tool such as tweezers, pliers or the user's fingers.

In the case of securing elements on both sides of the lower part, it is particularly advantageous if both securing elements are sliding elements according to the preceding description.

The object is also achieved according to the invention by a method for removing a turning axis from a self-inking stamp, which self-inking stamp is designed according to the above description, wherein the securing element is removed from the turning axis or a position in the extension of the turning axis and the turning axis is removed from the stamp unit in the longitudinal direction of the axis. In particular, the securing element is removed from at least one end of the turning axis, whereby one end of the turning axis is exposed and can be grasped, and the turning axis is removed in the longitudinal direction of the axis. After removing the turning axis, the stamp unit, which is now no longer supported in the lower part by the turning axis, can be removed from the lower part. To insert a stamp unit, i.e. the same or a different stamp unit, the stamp unit to be inserted is first inserted into the lower part and then the turning axis is inserted with the securing element still removed. inserted into the inserted stamp unit. The previously removed security element or possibly a new security element can then be placed over at least one accessible end of the turning axis. With regard to the features of the method, reference is also made to the preceding description of the self-inking stamp insofar as this is helpful for understanding the method and insofar as features of the method can be derived from this description of the self-inking stamp. Likewise, with regard to the features of the self-inking stamp, reference is also made to the description of the method.

The turning axis can be removed particularly easily if the securing element, in particular the sliding element, is moved away from the turning axis, in particular from at least one end of the turning axis. The removal of the securing element can therefore be a movement of the securing element. The securing element can be moved from a securing position to a release position. After replacing the turning axis, in particular the stamping unit, the securing element, in particular the sliding element, can be moved back into the securing position in order to cover at least one end of the turning axis and to secure the turning axis against axial advance.

It is particularly advantageous if the securing element, in particular the sliding element, is displaced in the lower part, in particular parallel to the actuation direction of the actuation part, or pivoted in the lower part, both for the release and removal of the turning axis and for any possible re-securing of a turning axis in the lower part. Removing the securing element can therefore be a displacement or pivoting of the securing element, in particular the sliding element. For example, the sliding element can be displaced upwards, i.e. in the direction away from a substrate to be printed on, or pivoted about a pivot axis in order to release the turning axis for removal.

For the movement of the securing element, in particular the sliding element, preferably through a recess or a through-opening in an outer panel of one side of the The securing element, in particular the sliding element, can be accessed through the lower part. To remove the turning axle, this can be brought into line with the recess or through-opening in the outer paneling by pressing down the actuating part and then removed through the recess or through-opening.

The removal of the turning axis can be carried out particularly easily if the securing element, in particular the sliding element, is moved from a second locking position in the lower part, in which the turning axis is secured in the lower part, to a first locking position in the lower part, in which the turning axis is released for removal from the stamping unit. The first and second locking positions define positions to which the securing element can be transferred and held by locking elements. Accordingly, the securing element can be moved by a user of the

Even the inking stamp can be moved between the first and second locking positions by overcoming the holding force of the locking elements.

It is particularly advantageous if the security element, in particular the sliding element, is moved by engaging in a stop for actuating the security element, in particular the sliding element, preferably in a recess or notch accessible from outside the lower part. A user of the self-inking stamp can thus move the security element by engaging in the stop using a simple tool that is generally available in a household or office, such as a paper clip or the tip of a ballpoint pen.

The turning axis can be removed from the self-inking stamp particularly easily by providing a securing element on both sides of the lower part and removing both securing elements from the turning axis or a position in extension of the turning axis, pushing the turning axis at least a little way out of the stamp unit from one of the two sides of the lower part and, if necessary, pulling it out completely from the other side.

Fig. 1 shows a self-inking stamp 1, in particular with over-stroke inking and with a turning mechanism W, which will not be discussed in detail below, in an inking position, standing on a base (not shown). The self-inking stamp 1 has a lower part 2, an actuating part 3, for example with a handle 3a, and a stamp unit 4. In the example shown, the stamp unit 4 is a type unit 4a, but could also be a stamp plate (not shown). The actuating part 3 is arranged above the lower part 2, connected to the lower part 2 and arranged so as to be displaceable relative to the lower part 2. The stamp unit 4 is arranged in the lower part 2 and connected to the actuating part

3 is pivotally coupled via a turning axis 5 (see e.g. Fig. 5A to 7). The turning axis 5 is removably mounted in the stamp unit 4 in the longitudinal direction L of the axis, i.e. in the longitudinal direction of the turning axis 5, see Fig. 6 and 7. A securing element 6 is arranged in the lower part 2 and limits a displacement of the turning axis 5, relative to the lower part 2, in the longitudinal direction L of the axis. The securing element 6 thus secures the turning axis 5 accommodated in the lower part 2 against axial advance, i.e. a advance in the longitudinal direction L of the axis. In order to be able to transfer the turning axis 5 reliably, without jamming, and as quietly as possible between the upper inking position and the lower printing position, the securing element 6 forms a sliding surface 7 for the turning axis 5, whereby the sliding surface 7 extends over the entire working area A of the turning axis 5. The turning axis 5 has a first end 8 and a second end 9. The working area A should be understood as the sum of all positions that an end 8, 9 of the turning axis 5 covers between the inking position and the printing position. The inking position in which the cliché 10 of the stamp unit

4 is inked is shown in Fig. 1, 2 and 8 and the imprint position in which a stamp impression is produced on the substrate to be printed is shown in Fig. 3 to 7. The sliding surface 7 forms a smooth impact surface 7a for the ends 8, 9 of the turning axle 5, without unevenness and without steps on which the turning axle 5 could get stuck or produce unpleasant noises.

The lower part 2 of the self-inking stamp 1 has two sides 11, 12 which are covered with an outer covering 13. In the example according to Fig. 1, the security element 6 is arranged between the outer covering 13 and the stamp unit 4. In addition, the outer covering 13 in the example shown has a recess 14, in particular a through opening 14a, for access to the security element 6. In the example according to Fig. 1, the lower part 2 has a self-contained frame 16 at its bottom end 15, which forms a base on the floor or is connected to feet 17, cf. Fig. 8, which form the base on the floor.

Fig. 2 shows the self-inking stamp 1 from the side, in the inking position, in which the actuating part 3 is arranged in its upper position, i.e. has not yet been pressed down into the impression position. A spring element (not shown) holds the actuating part 3 in this rest position. The securing element 6 covers the turning axis 5 and is thus in a securing position. By pressing the actuating part 3 down in the direction of the lower part 2, i.e. in the actuating direction B of the actuating part 3, the self-inking stamp 1 assumes the impression position shown in Fig. 3.

Fig. 3 shows the self-inking stamp 1 from the side, in the imprint position, in which the stamp unit 4 can produce a stamp impression on a substrate to be printed. In the illustration according to Fig. 3, the securing element 6 is shown in a release position in which the turning axis 5 is no longer covered by the securing element 6 and access to the turning axis 5 is possible. To release the turning axis 5, the securing element 6 is therefore removed from at least one end 8, 9 of the turning axis 5.

Fig. 4 shows the self-inking stamp 1 in an imprint position, with the outer covering 13 of the visible side 12 omitted in order to allow a view of the security element 6. lent. The securing element 6 is arranged in the recess 14 and is in a securing position covering the turning axis 5, in which a displacement of the turning axis

5 is limited relative to the lower part 2 in the axial longitudinal direction L.

Fig. 5A shows the self-inking stamp 1 according to Fig. 4 in a sectional front view and Fig. 5B shows the detail D from Fig. 5A in an enlarged view, whereby in Fig. 5A, in contrast to Fig. 4, the outer panels 13 of the side walls 11, 12 are shown. In particular, Fig. 5A shows two securing elements 6 in a securing position covering the turning axis 5. It can be clearly seen that the ends 8, 9 of the turning axis 5 are covered by the securing element 6 in the direction of the longitudinal axis L, whereby the turning axis 5 is secured against axial advancement. The securing element

6 forms a sliding surface 7 for the turning axis 5, so that the ends 8, 9 of the turning axis 5 can rest on the sliding surface 7 and slide over the entire working area A of the turning axis 5. The securing element 6 is shown as a one-piece sliding element 6a that is movable relative to the lower part 2. The one-piece design of the sliding element 6a promotes low-noise, preferably noiseless sliding of the turning axis 5 on the sliding element 6a. Due to the mobility of the sliding element 6a, it can be easily and quickly transferred from the securing position to the release position shown in Fig. 3 in order to expose one end 8, 9 of the turning axis 5 and remove the turning axis 5 if necessary. In the example shown, the sliding element 6a is designed as a slide element and is mounted displaceably in the lower part 2, in particular displaceably parallel to the actuation direction B of the actuation part 3. In an embodiment not shown but understandable to a person skilled in the art, the sliding element 6a can be pivotally mounted in the lower part 2 in order to allow access to the turning axis 5 by pivoting the sliding element 6a.

Fig. 1 to 9, 11 and 12 also show a stop 18 of the sliding element 6a. The stop 18 serves to actuate the sliding element 6a and can in particular be a recess 18a or notch 18b accessible from outside the lower part 2. By engaging the stop 18, the sliding element 6a can be removed from the end 8, 9 of the turning axis 5, in particular be pushed away.

Fig. 6 shows the self-inking stamp 1 in the imprint position, with the outer covering 13 omitted. The securing element 6, in particular the sliding element 6a, has been pushed up relative to the securing position covering the turning axis 5 (cf. Fig. 4) and is therefore in a release position which exposes the turning axis 5. In the example according to Fig. 6, the turning axis 5 has already been pulled out of the stamp unit 4 a short way. It can also be seen that the sliding element 6a has a first locking position PI in the lower part 2, with the turning axis 5 being released for removal from the stamp unit 4 in the first locking position PI. The first locking position PI therefore corresponds to the release position of the sliding element 6a, wherein the sliding element 6a is additionally locked in this release position in order to prevent undesired displacement, in particular slipping down of the sliding element 6a, as far as possible and to not hinder the removal of the turning axis 5.

In comparison to Fig. 6, the sliding element 6a in the illustration according to Fig. 4 has a second locking position P2 in the lower part 2, wherein in the second locking position P2 the turning axis 5 is secured in the lower part 2, i.e. cannot be moved significantly in the longitudinal direction L of the axis and cannot be removed. The second locking position P2 therefore corresponds to the securing position of the sliding element 6a, wherein the sliding element 6a is additionally locked in this securing position in order to prevent undesired displacement, in particular slipping upwards, of the sliding element 6a as far as possible and to keep the turning axis 5 secured.

Fig. 7 shows the self-inking stamp according to Fig. 6 in a sectional front view, whereby, in contrast to Fig. 6, the outer panels 13 of the sides 11, 12 of the lower part 2 are shown. A securing element 6 is provided on both sides 11, 12 of the lower part 2, whereby both securing elements 6 are sliding elements 6a. In the example shown, the left of the securing elements 6 is in the securing position corresponding to the second locking position P2 and the right securing element 6 is arranged in the first locking position PI corresponding to the release position. Of course, both securing elements 6 can be transferred to the first locking position PI in order to make the turning axis 5 accessible from both sides 11, 12. The turning axis 5 can be pushed from one side 11, 12 and removed from the other side 12, 11 by pulling it out.

Fig. 8 shows the self-inking stamp 1 in a partially assembled state, in which two securing elements 6 are inserted into the closed frame 16 but not yet inserted into the lower part 2. The frame 16 can be pushed into the lower part 2 together with the securing elements 6 and fixed to the lower part 2 via four hook elements 19. In order to be able to reliably accommodate and guide the securing elements 6, the frame 16 preferably has tongue-shaped insertion elements 20 which protrude upwards and are used to position the frame 16 in the lower part 2. A securing element 6 can be accommodated between each two insertion elements 20 so that it can move in the actuation direction B. In Fig. 8, the sliding elements 6a are pushed up as in the first locking position PI.

Fig. 9 shows the closed frame 16 with the securing elements 6 inserted therein, in particular sliding elements 6a, which are pushed downwards as in the second locking position P2. The frame 16 has an opening 21 for the passage of the cliché 10. In order to be able to releasably fix the securing element 6, in particular sliding element 6a, in the first locking position P1 and in the second locking position P2 in the lower part 2, the securing element 6, in particular the sliding element 6a, can have first locking elements 22 which interact with complementary second locking elements 23 on the insertion elements 20, which are components connected to the lower part 2. Preferably, the sliding element 6a has at least one locking recess 24, in the examples shown two locking recesses 24 on each side, such as locking notches 24a, as the first locking element 22, into which locking recess 24 at least one locking projection 25, in the examples shown one locking projection 25 on each side, can engage as the second locking element 23. In order to facilitate locking between the first and second locking elements 22, 23, tern, the insertion elements 20 are preferably designed to be resilient on the frame 16.

The securing element 6 can also be designed as a removable cover 26.

While Fig. 10 shows the frame 16 with the insertion elements 20 and the sliding elements 6a in a sectional view, without looking at the first and second locking elements 22, 23, in Fig. 11 the second locking elements 23 can be seen on the insertion elements 20. In Figs. 12 and 13 the first locking elements 22, which are designed as locking recesses 24, in particular locking notches 24a, can be seen on the sliding element 6a.

To remove the turning axis 5 from the self-inking stamp 1, the actuating part 3 is pressed down in the actuating direction B, whereby the turning axis 5 is brought into line with the recess 14 in the outer panel 13, the securing element 6 is removed from the turning axis 5 or a position in the extension of the turning axis 5, in particular by engaging the stop 18, moved from the second locking position P2 to the first locking position PI, and the turning axis 5 is removed from the stamp unit 1 in the longitudinal axis direction L through the recess 14.
