Description

The invention relates to an insert element for a stamp with a stamp frame for independent coloration of printed characters, with a plurality of juxtaposed setting wheels, which are arranged rotatably on an axis of an insert body and the dials are designed to carry Drucktybenbändern, with a Drucktybenbänder at least in Covering element covering the range of the dials, wherein the cover member comprises a basic body in cross-section with respect to the U-shaped with end portions spaced apart in the direction of the axis with end wall parts and in which the curved portion of the U-shaped body substantially along the peripheral region of Setting wheels extends, and the cover member is provided with slots for the passage of Einstellradumfängen and with at least one coupling device for coupling the cover member with the insert body, wherein the Coupling device comprises a first coupling element on the insert body and a cooperating second coupling element on the cover and the coupling elements are formed such that the relative coupling movement direction of the first and second coupling element is aligned with each other approximately in the direction of the axis of the insert body.

A band stamp comprising a one-piece plastic handle housing with a front and rear walls and two side walls and therein fixedly held handle discs with drums, which are wrapped by stamp bands with printing types, is from the DE 28 56 854 A1 known. In this case, the one-piece plastic housing forms the handle for operating the stamp and takes the individual stamp parts fixed therein. On the Gchäusevorderwand and the rear wall panels are formed, between which unilaterally open slots are released. In addition, a transverse web extending between the side walls is arranged in the stamp area, which can be plugged onto the housing side walls. This web is wrapped by the stamp bands and used during stamping to support the same. Through this bridge, the guide for the rotatable punch bands is achieved in cooperation with the one-piece handle housing.

From the DE 203 09 613 U1 is a date stamp, comprising a housing with a holder, a stamping frame and a protective cover, which has a U-shaped cross-section, known. The stamping frame is arranged pivotably on the holder of the housing, wherein a color pad is installed in the housing. The stamping frame has a plurality of shims and a plurality of punch bands, each of which is provided with a printing surface of letters, numbers and / or icons. For mutual connection of the protective cover with the stamping frame, on the one hand, the stamping frame has two clamping parts arranged on both sides on the lower part and, on the other hand, the protective cover has two fixation parts defined on both sides. The fixing parts of the protective cover are formed in the region of end wall parts thereof. The locking of the protective cover on the stamp frame is carried out by an expansion of the U-shaped legs in approximately vertical direction with respect to the axis of the shims. The deformation for the coupling process takes place mostly in the arcuate region of the U-shaped cross section of the protective cover. It could not be achieved in all Einlegeungsfällen a secure mounting of the protective cover on the punch frame.

From the WO 2006/079129 A1 is a hand stamp, in particular self-inking stamp, comprising an operating handle and a stamp housing with a turning mechanism for a type aggregate known. The type aggregate can be moved up and down with the aid of the actuating bracket and can be moved by 180 ° from an upper rest position into a lower, turned-over impression position. The type aggregate has several dials and type bands. Furthermore, a hood-shaped cover for the type bands is provided, which has slots for the passage of a peripheral part of the dials. Between the hood-shaped cover and a bearing part of the type unit, a coupling device for mutual latching is arranged. On both legs of the bearing part are provided on the side facing away from the type band outside two radially outwardly projecting locking lugs, which cooperate with cantilevered projections on the front side of the cover in the coupled position. The coupling process between the coupling elements takes place in the radial or vertical direction with respect to a longitudinal axis passing through the dials. It could not be achieved in all applications, a secure mounting of the hood-shaped cover in the direction of the axis of rotation of the dials.

From the AT 000 379 U1 is a cover sheet in the form of a U-shaped metal or plastic body has become known, provided in the slots for the passage of adjusting wheels and the cover, which covers Drucktybenbänder worn on hubs of the dials. For holding or fixing the cover, the insert body between the side parts extending front and rear cross members, which in turn have slots for receiving the inserted over the Drucktypenbänder cover. This makes it possible to insert the cover film with its slots on the dials far into the slots provided in the insert body until the cover is held by clamping in the insert body. However, it was not possible to achieve a secure and permanent support between the cover film and the insert body in all applications.

Further handstamps with a stamp housing, in which the printing type tapes with the adjusting wheels associated therewith are arranged stationary therein, are made of DE 2 156 157 A as well as the CH 258 021 A known.

The present invention has for its object to provide an insert element for a stamp, in which a positionally accurate and secure mounting of the cover can be achieved on an insert body of the insert element.

This object of the invention is achieved in that a guide device is arranged between the end wall part of the cover element and a side part of the insert body. The resulting from the features of the characterizing part of claim 1 advantage is that on the one hand the joining process or the sliding of the cover is facilitated by the guide device on the insert body and on the other hand an additional positioning with respect to the longitudinal axis of the adjusting wheels arranged on the axis can be achieved , As a result, not only a mutual pre-alignment between the components to be joined is achieved, but also a corresponding position positioning. In addition, an exact guidance and support between the cover and the insert body can be achieved. At the same time, however, it is also possible during the adjustment process of the individual setting wheels to inadvertently transfer forces transmitted to the covering element starting from the covering element onto the insert body. Furthermore, an even more secure connection as well as an exact mutual positioning between the components to be coupled is created by the selected relative coupling movement direction of the cooperating coupling elements in the direction perpendicular to the U-shaped cross-section of the cover. This is independent of the arrangement and position of the legs of the cover relative to the insert body. The mutual orientation of the cover with respect to the insert body also plays an important role in the interaction of the dials with the slots assigned to them in the cover. If the cover is held appropriately positioned in the direction of the axis, the play between the slot and the respective adjusting can be kept low without mutual contact or grinding takes place. Likewise, a declining bias of the U-shaped cover does not matter for the applied clamping force. An unintentional separation of the components by an adjustment or displacement of the legs of the cover thus result in no unintentional release of the coupling device, as can be done for example in the course of actuation of the dials. This is because the coupling movement direction is rotated approximately 90 ° with respect to the pressure force to be applied during the twisting movement of the dials for power transmission.

Also advantageous is a further embodiment according to claim 2, as a simple to produce coupling element can be created by simple means, which allows a secure, stable and durable support.

It is also advantageous embodiment according to claim 3, as a safe interaction with the coupling element formed by a receiving opening is ensured.

By the formation according to claim 4 or 5, it is possible to facilitate the release of the mutually engaged coupling elements for the deliberate removal of the cover from the insert body. Thus, it is now more necessary to bring the extension out of engagement with the receiving opening from the outside with a corresponding tool, wherein then the cover is easy to remove.

According to another embodiment according to claim 6 or 7, we created a simple to produce coupling element, which also ensures a secure and permanent mounting of the cover on the insert body.

Also advantageous is a development according to claim 8, since thereby a cover of the coupling element takes place from the outside through the cover.

Due to the design according to claim 9, it is possible to allow for an exact position positioning in the region of the axis an additional alignment movement of the cover in relation to the support plate or housing bracket.

In the embodiment according to claim 10 it is advantageous that thereby a directed from the outside in the direction of the center of the insert body coupling movement direction is provided and thus difficult for non-expert users, a release of the cover of the insert body or prevented.

Through the development according to claim 11 ensures that perpendicular to the joining direction of the components to be coupled together, namely the cover and the insert body, aligned contact surfaces are created, which prevent mutual release of the coupling elements.

By the embodiments according to claims 12 or 13, the material inherent elastic properties for the implementation of the coupling process can be used, in which case the main body of the cover can be formed with a higher inherent rigidity.

Through the development according to claim 14 it is achieved that as well as a certain coverage of the peripherally arranged dials can be achieved and still a perfect coupling operation of the coupling device forming coupling elements is made possible.

In the embodiments according to claims 15 to 18 it is advantageous that an additional cohesion of the individual wall parts of the cover is so achieved by the one or more connecting webs and beyond a directional power transmission and a higher stiffness of the interconnected coupling elements of the Coupling device can be achieved. Due to the arrangement of the connecting web in the apex portion or apex region of the cross-sectionally U-shaped cover member this is additionally stiffened seen in the direction of the axis. Thus, the slot width of the slot is kept constant by this connection in this area and avoided grinding or jamming of the dials during the adjustment.

The embodiment according to claim 19 or 20 makes it possible to prevent the leg ends of the cover element from pivoting in the direction of the printing type bands. As a result, not only the assembly is facilitated but also damage and possible mutual tilting and thus an increased effort for the adjustment can be avoided.

Finally, further, advantageous embodiments are characterized in the claims 21 to 22, wherein the achievable advantages of the description can be found.

The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

In the Fig. 1 to 3 is a possible and possibly independent training of a punch, in particular an insert element 1 with an insert body 2 for a stamp, which is designed for example as a date stamp, and individually designed to the respective date or other font and print characters adjustable shown. For the sake of simplicity, only the entire insert element 1 for the stamp has been illustrated here, wherein the other components for forming the stamp, such as, for example, the stamp frame and the independent inking of the printed characters and the like, do not belong to the present invention.

The insert element 1 is formed in this present embodiment by a support plate 3, a housing bracket 4 with side parts 5, 6 and an axis 7. The support plate 3, a housing bracket 4 with side parts 5, 6 and an axis 7 is formed. The support plate 3 has in its center on an opening for the stamp part, so as to ensure a perfect support on the surface provided for the stamp order on the one hand and on the other hand also to wear or record other printed characters.

The insert body 2 is further assigned a Einstellrädersatz 8 with a plurality of Einstellrädern 9, which are formed rotatably mounted about the axis 7. The dials 9 serve to support printing type tapes 10, wherein the dials 9 form a Einstellradumfang 11 at its outer periphery. To cover the printing type bands 10, a cover element 12 is provided at least in the area of the Einstellrädersatzes 8, this side by side in response to the individual Einstellrädern 9 provided slots 13 for the passage of at least the Einstellradumfanges 11 of the dials 9 has. In this case, the cover 12 has a base body 14, wherein this is formed in its cross section with respect to the axis 7 U-shaped. Characterized in that the Einstellradumfänge 11 pass through the slots 13 and the base 14 of the cover 12 covers the arranged between the dials Drucktybenbänder 10 is for a user of such insert element 1 upon actuation of the dials 9, a contamination of the fingers by the already used or used printed characters avoided with the still adhering stamping ink.

The printing type bands 10 may have a different width in the direction of the axis 7, depending on the printing or stamp characters arranged thereon. In the area of the support plate 3, the printing type tapes 10 are associated with a guide which is not described here in detail, which aligns the printed characters arranged on the printing type tapes 10 in a planar manner with respect to the stamp surface or its surface. As a result, a whopping investment and an associated, perfect stamping result is achieved in a known manner.

For holding or coupling of the cover 12 with the insert body 2, at least one coupling device 15 is provided between them. This coupling device 15 in turn has cooperating coupling elements 16, 17 on the insert body 2 or on one of its constituent components and on the cover element 12. The cooperating coupling elements 16, 17 are designed such that the relative direction of coupling movement of the coupling elements 16, 17 is aligned with each other approximately in the direction of the axis 7 of the insert body 2. This means based on the U-shaped Formation of the main body 14 of the cover 12, that the coupling movement direction is aligned approximately in the vertical direction with respect to the U-shaped cross-section. By aligned approximately in the direction of the axis 7 clutch movement direction unintentional release of the cover 12 can be prevented during the adjustment of the Einstellradumfang 11 of the dials 9.

By means of a double arrow is in the Fig. 2 the coupling movement direction of the cooperating coupling elements 16, 17 shown, wherein for the coupling process, first the coupling elements 17 with the side wall portion 24, 25 to the adjustment wheels 9 facing direction - to adjust - ie inward. With appropriate alignment and position to each other then the coupling element 17 of the cover 12 can be brought into engagement with the first coupling element 16 in the region of the side part 4, 5. At the same time during the joining process, however, an elastic deformation of the side part 5, 6 of the insert body can take place.

Best is the coupling device 15 from a synopsis of Fig. 2 and 3 to see. Here, the first coupling element 16 is formed by a receiving opening 18 in the region of the side part 5, 6 of the insert body 2. In this case, the side part 5, 6 may be part of the support plate 3 and / or the housing bracket 4.

The cover element 12 has the above-described, in its cross-section U-shaped base body 14 and in the direction of the axis 7 spaced-apart end portions 19, 20. In the region of these end regions 19, 20, the coupling element or elements 17 is arranged on the cover element 12, which coupling elements are formed here by an extension 21. This designed as an extension 21 coupling element 17 engages after appropriate mutual adjustment or displacement of the cover 12 out in the vertical direction on the axis 7 in the formed by the receiving opening 18 coupling element 16 a. In this case, the further coupling element 17 protrudes into the side turned away from the setting wheels 9. Thus, the first coupling element 16 is arranged with respect to the further coupling element 17 on the side facing away from the setting wheels 9 and are thus distanced from each other the farthest. Preferably, on both side parts 5, 6 of the insert body 2 as well as on the end portions 19, 20 of the cover element 12 facing the latter, there is in each case a coupling device 15 with the coupling elements 16, 17 forming these intended. Furthermore, the axis 7 preferably extends between the side parts 5, 6 of the insert body 2 and supports the setting wheels 9.

The first coupling element 16 with its receiving opening 18 is formed here approximately bow-shaped and has on the joining side of the cover 12 side facing a preferably planar trained contact surface 22 which cooperates with a projection 21 formed on the other contact surface 23 in the coupled position and prevents unintentional removal of the cover 12 from the insert body 2. For ease of joining, the extension 21 seen in the coupling or joining direction has a bevelled guide surface, so as to facilitate the joining or coupling process. The two contact surfaces 22, 23 are aligned with respect to the axis 7 parallel to this. Preferably, the contact surfaces 22, 23 are also arranged parallel to a printing plane not shown here for receiving the printed image.

The cover member 12 has in addition to the main body 14 at its two end portions 19, 20 each at least partially covering end wall portions 24, 25. In this case, the further coupling element 17 or the extension 21 is preferably arranged on these end wall parts 24, 25. To facilitate the joining movement of the end wall part 24, 25 is resiliently connected to the base body 14 of the cover 12.

The relative coupling movement direction between the coupling elements 16, 17 taking place in the direction of the axis 7 can take place during the dome operation by corresponding displacement of the side part 5, 6 and / or the end wall part 24, 25. This displacement movement can be easily and safely realized in plastic, for example, by an injection molding process, components produced by the material inherent elastic properties. Likewise, however, material weakenings may also be provided at predetermined points which form a kind of joint, but in the coupled position the side parts 5, 6 and / or the end wall parts 24, 25 have sufficient strength or stability in maintaining their relative position for the cooperating one Coupling elements 16, 17 have.

Furthermore, at least one guide device 26 is provided between the end wall part 24, 25 of the cover element 12 and the side part 5, 6 of the insert body 2 is. This guide device 26 serves, on the one hand to facilitate the joining process or the sliding of the cover 12 on the insert body 2 and on the other hand to achieve additional positioning with respect to the longitudinal axis of the adjusting wheels arranged on the axis. As a result, not only a mutual pre-alignment between the components to be joined is achieved, but also a corresponding position positioning. In addition, an exact guidance and support between the cover 12 and the insert body 2 can be achieved. At the same time, however, it is also possible during the adjustment process of the individual setting wheels 9 to inadvertently transfer forces transmitted unintentionally to the cover element 12 starting from the cover element 12 towards the insert body 2. An additional limitation of the coupling movement between the cover element 12 and the insert body 2, in particular the housing bracket 4, is possible by means of corresponding cooperating guide parts of the guide device 26.

Regardless of this, it would also be possible to arrange the previously described coupling elements 16, 17 laterally reversed or mutually mirror-inverted on the cover element 12 or on the side part 5, 6. Thus, the receiving opening 18 in the side wall part 24, 25 and the extension 21 on the side part 5, 6 would be arranged or formed.

In the 4 to 6 is a further and optionally independent embodiment of the insert element 1 is shown, again with the same parts the same reference numerals or component designations as in the preceding Fig. 1 to 3 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used Fig. 1 to 3 referred or referred.

These here in the 4 to 6 illustrated coupling device 15 between the cover 12 and the insert body 2, in turn, also has the cooperating coupling elements 16, 17, in which case in contrast to the previously in the Fig. 1 to 3 shown coupling device 15, the first coupling element 16 is formed by a receiving opening 27 in the axis 7. Preferably, the receiving opening 27 is cylindrical in the axis 7. The further coupling element 17 is formed in the direction of the dials 9 protruding as a cylindrical approach. It thus engages in the coupling position from the outside in the direction of the axis 7 in the receiving opening 27 formed there. On the side part 5, 6 on the one hand for the storage of the axis 7 in approximately half-shell-shaped bearing points 28 and on the other hand for supporting a support member 29 of the cover 12 provided support surfaces 30 are formed. The support member 29 serves as an intermediate piece between the end wall part 24, 25 and the pin-like coupling element 17 of the coupling device 15th

By means of a double arrow is in the Fig. 5 the coupling movement direction of the cooperating coupling elements 16, 17 shown, wherein for the coupling process, first the coupling elements 17 with the support member 29 and side wall portion 24, 25 in the direction away from the dials 9 direction - ie outward - to adjust. Only with appropriate alignment and position to each other, the coupling element 17 of the cover 12 can be brought into engagement with the first coupling element 16 in the region of the axis 7. Again, this elastic movement for the coupling process can be effected by the inherent properties of the components of the material, in particular if they are made of an injection molded part made of plastic. However, other materials would also be conceivable, such as metallic materials or else fiber-reinforced plastics, wherein it should always be ensured that the relative direction of coupling of the coupling elements 16, 17 with respect to the axis 7 of the insert body 2 is approximately in the same direction.

In all these embodiments described above, a central arrangement of the cooperating coupling elements 16, 17 is always provided on each side. This takes place mostly in the region of the axis 7 or a plane running concentric with the U-shaped limbs of the base body 14. A further support of the cover 12 in the coupled state also takes place on the support plate 3, whereby a so-called three-point bearing for the cover 12 on the insert body 2 is achieved. The coupling elements 16, 17 described above can cooperate in the form of a snap connection, wherein here also seen in the direction of the axis 7 alignment can take place.

The embodiments show possible embodiments of the insert element 1, in particular its coupling device 15 between the cover 12 and the insert body 2, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather also various Combinations of the individual variants with each other are possible and this possibility of variation due to the doctrine of technical action by objective invention in the skill of those working in this technical field is the expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.

In the Fig. 7 to 10 a further and possibly separate embodiment of the insert element 1 is shown with an insert body 2 for a stamp, again for like parts, the same reference numerals or component names as in the preceding Fig. 1 to 6 be used. In order to avoid unnecessary repetition, the detailed description in the previous ones will be used Fig. 1 to 6 referred or referred.

The coupling device 15 shown here between the cover 12 and the insert body 2 is the same acting as that coupling device 15 is formed, which is already in the Fig. 1 to 3 has been described in detail. Here again, the coupling device 15 has the respectively cooperating coupling elements 16, 17 on the insert body 2 or on one of its constituent components and on the cover element 12. The cooperating coupling elements 16, 17 are again designed such that the relative direction of coupling movement of the coupling elements 16, 17 is aligned with each other approximately in the direction of the axis 7 of the insert body 2. This means based on the U-shaped configuration of the base body 14 of the cover 12, that the coupling movement direction is aligned approximately in the vertical direction with respect to the U-shaped cross-section.

In the before in the Fig. 1 to 6 described embodiments of the cover 12 end the slots 13 for receiving the dials 9 each before reaching the ends of the legs of the body 14 and there are limited by a web-like component, which in turn in the embodiments according to the Fig. 1 to 6 is supported on the support plate 3.

The cover 12 is in this and the previously described embodiments by individual strip-shaped wall parts 31 are formed, between which the slots 13 are formed. These wall parts 31 are connected in each end region of the legs of the base body 14 by a holding web with each other to a common component. To increase the stability of the wall parts 31 and / or the coupling device 15, the cover 12 has at least one additional connecting web 32 at least in the region or section of its apex in the transitional region between the legs of the U-shaped component. This connecting web 32 extends in a direction parallel to the axis 7 between the mutually distanced end portions 19, 20, is connected to the wall parts 31 and preferably formed continuously. This orientation can also be referred to as perpendicular to the cross section of the cover 12. In this embodiment, here the connecting web 32 is not only connected to the wall parts 31 but also to the side wall parts 24, 25 carrying or receiving the coupling elements 17. Thus, the object of the invention can also be seen to provide a cover 12, which in particular in the region of its individual by the slots 13 separate wall portions 31 has a higher strength or rigidity. This can be absorbed by the entire cover 12 higher load. This load on the cover 12 can be introduced by the formation and operation of the coupling device 15 and during the assembly process on the insert body or during the adjustment of individual Einstellrädern 9 on this. This task can be seen independently of the design of the coupling device 15. In this case, a multiple arrangement of the connecting web 32 over the extension path of the slot 13 in cross-section of the cover 12 is possible.

The connecting web 32 extends in the radial direction with respect to the dials 9 seen in a selected, larger distance such between the end portions 19, 20 and the end wall parts 24, 25, that on the one hand unhindered recording of the dials 9 and an associated adjustment is possible and On the other hand, a stable cohesion of the individual wall parts 31 is provided on the side facing away from the axis 7 region of the dials 9. The Einstellradumfänge 11 of the dials 9 are spanned while maintaining a radial distance from the connecting web 32. This serves to contact-free recording of the individual setting wheels 9 in the region of the connecting web 32. This connecting web 32 can be seen in cross-section - ie in the direction of its longitudinal extension or in the direction of the axis 7 - also U-shaped, as best of the Fig. 10 can be seen. In this case, the connecting web 32 is formed raised with respect to an outer surface of the individual wall parts 31 and projects beyond this surface to the side or the direction away from the axis 7. As a result, in addition to a stable coupling device 15, a high stability of the entire cover element 12 is also achieved in its vertex section. As a result, the Auslangen can be found with smaller wall thicknesses and still sufficient strength for both the cover 12 and the coupling device 15 formed thereon can be achieved.

The connecting web 32 with the here arranged or associated end wall parts 24, 25 forms a likewise U- or C-shaped arrangement, which, however, with respect to the U-shaped cover member 12 is arranged offset by 90 ° thereto. In both U-shaped components, the legs or end wall parts 24, 25 protrude in the same direction.

The end wall parts 24, 25 in turn carry the previously described coupling elements 17 and at the same time also form the guide device 26 for alignment with respect to the housing frame 4.

As a result of this additional connecting web 32, deformation of the side wall parts 24, 25 in the direction of the axis 7 is possible in order to bring the coupling elements 16 and 17 into or out of engagement with one another. For this purpose, a gap is formed between the end wall parts 24, 25 and the immediately adjacent wall parts 31, which may correspond to the width of the slot 13 in its clear width, for example, for receiving the respective adjusting 9 of the slot or may be slightly larger. This is dependent on the arrangement and design of the coupling elements 16 on the housing bracket 4 and the side parts 5, 6. If a slightly wider or larger gap is selected, the coupling process between the two cooperating coupling elements 16, 17 is easier to perform. Due to the arrangement of the connecting web 32, however, a sufficient strength of the entire cover element 12, in particular also its coupling device 15, is nevertheless achieved in this area.

In contrast to the previously described embodiments of the cover 12, here an adjustment or pivoting of the side wall portions 24, 25 takes place about a pivotally arranged centrally in the apex portion of the cover 12 pivoting range by Einwertsschwenken of the two end wall parts 24, 25. In the previously in Fig. 1 to 6 described embodiments, the side wall portions 24, 25 but given away around a arranged in the region of the leg ends pivoting range. As a result, based on the cross-sectional plane of symmetry of the U-shaped cover member 12 and its wall parts 31, an eccentric adjustment or pivoting of the end wall parts 24, 25 takes place during the coupling process.

The remote from the connecting web 32 ends of the wall parts 31 in the region of the leg ends of the U-shaped cover member 12 may in turn be connected together to form a one-piece component. This in turn improves the stability of the individual wall parts 31, in particular against deformation in this area. The leg ends of the cover 12 in the region of the wall parts 31 protrude into the support plate 3 within a web 33 in this. As a result, an unintentional widening of the legs of the U-shaped cover member 12 is avoided in this area. In addition, however, a corresponding support and an associated stabilization of the cover 12 relative to the support plate 3 is also possible.

For the assembly of the cover 12 on the housing bracket 4, a sliding over of the cover 12 via the dials 9 by the elastic expansion of the legs of the cover 12 is possible. This insertion movement takes place until the coupling elements 16, 17 of the coupling device 15 are engaged with one another. This delaying movement is facilitated by the guide device 26 described above in the region of the side wall parts 24, 25 and the housing bracket 4. A stop limit for the insertion movement may also be provided in the region of the guide device 26, which best from the Fig. 7 can be seen. In this case, components or webs of the guide device 26, which are arranged in the region of the end wall parts 24, 25, based on cooperating support surfaces or support edges on the housing bracket 4 and its side parts 5, 6 from.

In the Fig. 11 to 13 a further and possibly separate embodiment of the insert element 1 is shown with an insert body 2 for a stamp, again for like parts, the same reference numerals or component names as in the preceding Fig. 1 to 10 be used. To avoid unnecessary repetitions will be on the detailed description in the previous Fig. 1 to 10 referred or referred.

The coupling device 15 shown here between the cover 12 and the insert body 2 is the same acting as that coupling device 15 is formed, which is already in the Fig. 1 to 3 or 7 to 10 has been described in detail is therefore not discussed in detail again.

The cover member 12 forms at its in the direction of the axis 7 of each other distant end portions 19, 20 end faces 34, 35 and end faces, on which mutually aligned support members 36 are arranged. These support elements 36 serve to ensure that the cover element 12 is supported on a housing region 4 provided for this purpose in the position in which it is mounted on the housing bracket 4. Thus, an assembly aid is achieved by which the assembly of the unit from the housing bracket 4, the Einstellrädersatz 8 and the cover 12 is facilitated with the support plate 3. In addition, it is also possible that the support elements 36 seen in the insertion direction, even on the support plate 3 and a component thereof support and so form an additional limitation of the insertion movement of the cover 12 relative to the support plate 3. Thus, not only the collapsing of the U-shaped cover member, in particular its wall parts 31, can be avoided, but also an exact positioning of the cover 12 with respect to the support plate 3 and the Einstellrädersatz 8 can be achieved.

By the guide device 26, the cover member 12 is positioned accurately in its top portion with respect to the Einstellrädersatzes 8 and the support plate 3 in its position. As a result, a trouble-free adjustment process of the individual printing type belts 10 is made possible by the setting wheels 9.

For the sake of order, it should finally be pointed out that, for a better understanding of the construction of the insert element 1, this or its constituent parts have been shown partly unevenly and / or enlarged and / or reduced in size.
