Description

The invention relates to a receiving device for a carrying device of an ink pad, as described in the preamble of claims 1, 4, as well as a stamp, as he is characterized in the claims 17, 18.

There are already different receiving devices for ink pads or support devices known, as for example from WO 01/83227 A1 of the Applicant. Such Receiving device is arranged in a lower part of a multi-part stamp housing. The lower part of the stamp housing is formed like a hollow prism and has a approximately rectangular cross-section on. In the direction of the longitudinal axis of the hollow prism are connected to the two narrow sides of the lower part parallel to the longitudinal axis extending guideways for Recording of guide elements of the upper part arranged. The top is over one Lever mechanism with a pressure plate carrier motion coupled and over at the two Inner sides of the narrow sides of the lower part formed link tracks pivot guided. The movement associated with the printing plate support top of the housing is about a arranged between this and the lower part spring in a stop limited Rest position held such that the guide elements of the upper part in this facing end portion of the guideway of the lower part are. In this rest position the printing plate support is applied to the ink pad, which faces in a the upper part End face of the lower part, in particular in a direction transverse to the longitudinal axis of the hollow prism extending guideway slidably mounted for a support device of the ink pad is. To replace the ink pad, the printing plate support in the direction of moved from the ink pad opposite end face of the hollow prism and optionally locked. Then the ink pad can be removed transversely to the longitudinal axis or with the support device along the guideway are moved so far that the ink pad exchanged or the support device together with the ink pad from the Lower part can be removed. To hold the carrying device of the stamp pad in the use or use position is a locking device between the lower part and provided the support device, which is formed with elastically recoverable locking elements can be.

Furthermore, it is already known in a stamp, between the support device for the Ink pad and the lower part of the housing cooperating with roughening Provide locking lug to when pulling or pushing the support device a To achieve braking effect and the speed with which the support device opposite the housing can be adjusted to limit.

These known punches have proven themselves very well in practice. It could, however, at Removing the ink pad from the housing in some cases contamination of the Hands of the user can not be avoided by stamping ink.

The present invention is based on the object, the arrangement and / or training the stamp pad or its support device to be designed so that an exchange of the Stamp pad without or with reduced risk of contamination of the user or the environment is possible.

This object of the invention is solved by the features in claim 1.

The advantage here is that the ink pad with a part of the stamp, in particular can be brought with a housing part in a position in which an exchange of Stamp pad is easy and safe to handle. An immediate capture of the stamp pad or the carrying device for removal from the stamp or from its housing is not required and can thereby cause an unpleasant or annoying Pollution of the operator can be avoided. It is also possible Save components because the recording for the ink pad directly in one piece on a Without this required component, in particular on a wall portion of the punch or its housing-like receiving device can be formed.

The advantageous development according to claim 2, it is possible, the sheet-like component continue to use the stamp housing and only the ink pad along with the Replace carrying device.

The advantageous embodiment according to claim 3 gives a practicable, extended handle for the exchange or assessment of the stamp pad.

The task can also be solved by the features of claim 4.

An advantage of this solution is that the ink pad or its support device now not only in the working position for inking or re-inking the print plate carrier arrested or is positioned, but on the path of movement for removal at a further stop limited and / or positioned is held. This has the operator when changing or soaking the ink pad the possibility of the ink pad or its carrying device, after it already over part of the length of the guideway has been moved and protrudes from the bottom of the case, sure so gripped can be used to prevent contamination or minimize the risk of contamination is. Also, inadvertent unlocking of the first fixing or holding device to secure the working position of the ink pad or its carrying device an accidental and unforeseen falling out of the ink pad or its support device avoided.

Advantageous developments and detail embodiments are described in claims 5 to 13. The achievable advantages and effects are shown in the description of the figures.

In the development according to claim 14 is advantageous that the support device for the Ink pad does not need to be taken directly to a visual inspection or a To be able to exchange it.

A fully functional, yet cost-effective movement connection between the support device and the handle is proposed in claim 15.

A stamp formed according to the invention is characterized in claim 17.

An independent solution of the object of the invention is specified in claim 18.

It is advantageous in this embodiment that the ink pad or its often as well Carrying device contaminated with stamping ink is not directly detected by a user or touched to make a check or an exchange of the ink pad to be able to. The risk of contamination of the user's fingers or clothes can by this mechanical manipulation aid on a stamp according to the invention so be significantly reduced. In addition, can be visually clearly identified be that this handle on the stamp for displacement or adjustment of the ink pad serves, whereby the individual functions of the stamp are clear and awkward or erroneous handling can be largely avoided.

Due to the configuration according to claim 19, on the one hand a space-saving rest position and an optimum in terms of efficient force application and favorable force application zone Active or working position can be achieved.

An inexpensive, relatively movable connection between the support device and the Handle, with which also a sufficient robustness can be achieved, is in claim 20 specified.

An additional safeguard for fixing or blocking the movability of the stamp pad opposite the die housing is specified in claim 21. It can do that as well in the case of impact loads, such as occur when the punch falls to the ground, not to slip out of the ink pad and no more to dirt, For example, the bottom area, come.

Due to the advantageous embodiment according to claim 22 can be prevented in a simple manner be a carelessly positioned handle hinders a stamping process or the tab-like handle is torn off or damaged when the upper part abruptly pressed down against the lower part.

A defined initial or rest position of the handle can by the configuration can be maintained secured by simple means according to claim 23.

Due to the alternative embodiment according to claim 24, the actuating element of the Stamps are also pulled over the cushion holder, thereby advantageously and It creates a relatively large grip surface and ergonomic operation of the Stamp is favored.

In FIGS. 1 to 3, a stamp 1 designed according to the invention is shown in a simplified, schematic manner Presentation illustrated.

This stamp 1 is designed as a so-called self-inking, in which a Nachtränken the stamp surface with printer or stamp ink, preferably ink, automatically done. For this purpose, in the stamp 1, which consists essentially of an upper part 2 and a lower part 3, an ink pad 4 is arranged. This stamp pad 4 has sponge-like Properties on, allowing it to store a certain supply of stamp ink or ink and in the longer term. To the characteristics and / or the quality of with To change the stamp 1 producible stamping pressure, the ink pad 4 is in Stamp 1 replaceable held. Preferably, the ink pad 4 is in an inverted or "upside down", frame or box-like support device. 5 taken and via the relatively dimensionally stable support device 5 in the lower part 3 of the Stamp 1 held replaceable if necessary. The type of a receiving or holding element formed for the ink pad 4 carrying device 5 is at the bottom delimited by dye-saturated ink pad 4. The arrangement and orientation of the Stamp pad 4 and an adjustment mechanism in the stamp 1 is chosen such that a alternately contacting with a relative to the lower part 3 relatiwerstellbaren stamp plate 7 with the characters or graphics to be stamped and a color transfer to the area to be stamped is possible. This stamp plate 7 can be made from within the stamp 1 swiveling and adjustable pressure plate carrier 8 and one of the desired Graphic or the desired characters having printing plate - not shown - consist. Alternatively, it is also possible, if necessary interchangeable on the printing plate support 8 or to apply different stamp graphics or character sets. Of course but it is also possible, the stamp plate 7 directly with the desired characters, To provide texts or graphics and to make the stamp imprint unchangeable.

The upper part 2 may be formed by a hood-like actuator 9, with the Lower part 3 is connected and in particular includes the upper edge region of the lower part 3. The upper part 2 and the lower part 3 are telescopically via a guide arrangement 10, 11 adjustable to each other. In such a relative adjustment of the upper part 2 opposite the lower part 3 by depressing the actuating element 9 experiences the pressure plate carrier 8 both a translational movement, as well as a rotational movement, in particular a Turning movement and is doing towards a footprint 12 of the stamp 1, which is usually formed by a sheet of paper to be stamped, moves. This is in the stamp 1 a not described in detail, known from the prior art turning and displacement mechanism 13 formed for the printing plate support 8. These turning and Displacement mechanism 13 thereby provides a movement connection between the actuating element 9 or the upper part 3 and the pressure plate carrier 8 such ago, that the latter starting from its position shown in Fig. 2, in which it with the ink pad 4 in contact is, in a pivoted by 180 °, deeper position in which he with the to be stamped Underlay comes in contact, and vice versa, spent.

The actuation of the punch 1 takes place counter to the force of a spring 14, preferably in the form of a compression spring. This spring 14 causes an automatic reset of the punch 1 in the rest or home position shown in Figs. 1 and 2, in which the printing plate carrier 8 is in contact with the ink pad 4 and exerts a defined contact pressure on the ink pad 4. The stamp plate 7 is thus limited via the turning and shifting mechanism 13 in the stamp 1 as translational also limited rotational in a direction parallel to the direction of actuation - arrow 15 of the actuating element 9 extending channel 16 in the lower part 3 adjustable. Especially there is a forced movement coupling between the actuator 9 and the Stamp plate 7 and the pressure plate carrier 8. This channel 16 can - especially in Dependence of the shape of the stamp plate 7 and the pressure plate carrier 8 - square, for example rectangular or square, or even oval or circular cross-section exhibit.

To a simplified exchange or a simplified Nachtränken the ink pad 4th if necessary, a locking device 17 between the upper part 2 and the lower part 3 within the guide length of the guide assembly 10, 11 are provided. This locking device 17 allows a determination of the upper part 2 relative to the Lower part 3 in a region between the illustrated in FIGS. 1 and 2 starting or Rest position and the active position in which the stamp plate 7 an impression on the Can produce footprint 12. In particular, by means of this locking device 17th a demand-setting or temporary locking of the printing plate support 8 in allows a defined distance to the ink pad 4. In this not shown, as needed einnehm- and cancelable intermediate or Feststellage, is the pressure plate carrier 8 not in direct contact with the ink pad 4, so that the ink pad 4, preferably together with the frame-like support device 5, easily removed from the stamp 1 or at least can be pulled out of this.

This locking device 17 at an intermediate position between the ink or ink receiving Position - Fig. 2 - and a color or ink-emitting position of the printing plate support 8 can by corresponding recesses 18 and elevations 19 am Lower part 3 and / or on the upper part 2 are formed. By means of this activated as needed and preferably automatically deactivatable locking device 17 may also be too long-lasting Wetting of the printing plate support 8 and the stamp plate 7 with stamping ink turned off. In particular, by continued depression of the actuating element 9 in the direction of actuation - arrow 15 - can the locking device 17 automated To get picked up. This is by means of pretensioning mutually displaceable chamfers or hooks on the corresponding recesses 18 and elevations 19 in a simple manner and way allows. A possible shape for the recesses 18 and elevations 19 for achieving an automatic or automatic deactivation of an activated locking device 17 is illustrated in FIG. 1.

If necessary, it is also possible to activate as required and a conscious or to provide active deactivation of the locking device 17. This can be prevented that the actuator 9 unintentionally or unforeseen in the active or stamping Working position is moved. As a result, it can, for example, during the transport of the Stamp 1 no longer for unwanted stamping or contamination of the surrounding area or come from surrounding objects.

In this determined by the locking device 17, if necessary, ingestible locking or intermediate position, is a withdrawal or removal of the support device 5 with the Stamp pad 4 made possible easily from the stamp 1, since the Ausschub- or Ausschwenkbewegung of the ink pad 4, together with its support device 5 not by the Stamp plate 7 and the printing plate support 8 is hindered.

As best seen in Fig. 2 it can be seen, the support device 5 for the ink pad 4 is preferred in the lower part 3 exchangeably held. For this purpose is in the upper edge area of the lower part 3 a shaft 20 is formed, in which the ink pad, in particular the support device 5 together with the ink pad 4, is interchangeable or at least inserted and at least can be partially pulled out. This slot 20 is doing a recording for the substantially rectangular ink pad 4 with this partially surrounding Carrying device 5 is. This shaft is preferred - as illustrated in Fig. 2 - designed as a breakthrough, which is transverse to the longitudinal direction or transverse to the actuation direction - Arrow 15 - of the stamp 1 extends. This makes it possible the carrying device 5 with the ink pad 4, starting from two opposite sides or wall surfaces of the punch 1 with respect to the lower part 3 push out or insert. In the in Fig. 2 shown working position closes the support device 5 of the stamp pad 4 in essentially flush with opposite wall surfaces 21, 22 of the lower part 3. Thereby is ensured that the telescopic relative adjustment between the upper part of the second and the lower part 3 is not hindered and on the other hand, a secure and stable recording in the Shaft 20 of the lower part 3 can be created.

The lower part 3 of the stamp 1 thus also represents a housing-like receiving device 23 at least for the carrying device 5 of a soft-elastic stamping pad 4, wherein in the end of the receiving device 23 facing the actuating element 9 the transverse shaft 20 for exchangeable receiving the support device 5 is formed is. The shaft 20 opposite Stirnendbereich the hollow prismatic Receiving device 23 has an opening or an opening whose cross-section at least the size or the cross section of the pressure plate or the stamp plate 7 corresponds.

The receiving device 23 or the lower part 3 is thus made hollow or frame-like and at least supports the support device 5 for the ink pad 4. Preferably, the Recording device 23 also for guiding the stamp plate 7 and the pressure plate carrier 8 formed within the frame-like or in the form of a hollow prism or chute Receiving device 23. Vertical guides 24 for stub axle 25 of the printing plate carrier 8 are preferably in the region of opposite narrow sides 26, 27 of the Stamp 1 or the lower part 3 or the corresponding receiving device 23 is arranged.

In a generic self-inking in the previously described or in a the corresponding, equivalent embodiment, the invention provides that the Color pad, in particular the support device 5 with the ink pad received therein 4, not uncontrolled fall out of the shaft 20 when the working or use position of the ink pad 4 is left - for example, the ink pad 4 alone or replace or nachzutränken together with the support device 5. Thereby can Contamination of the operator or peripheral objects are avoided. This can be on the one hand be achieved in that in the shaft 20 for the interchangeable or at least relatively adjustable Recording the support device 5 for the ink pad 4 at least two in Off or insertion direction - according to arrow 28 - the stamp pad 4 distanced each other Latching or stop elements 29, 30 on the receiving device 23 in the area around the Shaft 20 or in the shaft 20 and / or on the support device 5 of the stamp pad 4 is formed which are a first and at least one second holding device 31, 32 for the Stamp pad 4 relative to the shaft 20 and stamp 1 or with respect to the receiving device 23 form. This ensures that the support device 5 with the ink soaked Stamp pad 4 is positioned in at least two different positions held or in a position, in particular in a use or working position 33, positioned held and in at least one other position in his free Ausschubbewegung the shaft 20 is limited, this Endlagen- or stop limit as needed preferably can be canceled or overcome, so that the ink pad 4 together with the support device 5 are completely removed from the stamp 1 and the receiving device 23 can.

The first, secured by the locking or stop elements 29 of the first holding device 31 Position, is defined by a use or working or use position 33, as can be seen in Fig. 2. The distanced, further position is replaced by a substitute or maintenance position 34 defined, in which the support device 5 opposite the lower part 3 and the receiving device 23 protrudes, however, by means of at least one Stop or stop element 29 or 30 at an uncontrolled falling out of the Shaft 20 is prevented. Only through additional and above all conscious application of a increased removal force of the operator of the punch 1 on the support device 5, the Holding or positioning force of the other or second, to the first locking or stop element 29 distanced locking or stop element 30 overcome and the support device 5 are completely removed from the stamp 1 together with the ink pad 4. The inkpad 4 can in the extended replacement or maintenance position 34 either with appropriate Be inked and returned to the working or use position 33rd be spent by the operator exerts appropriate pressure on the support device 5. It is also possible, a used ink pad 4 together with the support device. 5 replace with a new ink pad 4 by inserting a support device 5.

In the replacement or maintenance position 34, a portion of the support device 5 projects at least so far opposite the receiving device 23 and against the lower part of the third of the stamp 1, that the carrying device 5 can be gripped securely by the operator, without the risk of slipping or direct contact of the dye-soaked Stamped pad 4 to be exposed.

The distances in the insertion or insertion direction - arrow 28 - along the shaft 20 to each other Latching or stop elements 29, 30 can be identical and mirror-symmetrical be arranged to a transverse plane 35 of the shaft 20. This will achieve that the carrying device 5, starting from any wall surface 21 or 22 in the direction pushed to the opposite wall surface 22 or 21 at least limited stop can be. The in leadership or Ausschieberichtung the support device 5 to each other distanced latching or stop elements 29, 30 are preferably identical, can but of course also be constructed differently to a determination of the support device 5 and the stamp pad 4 in the working or use position 33, and in to accomplish a removal or replacement or maintenance position 34 distancing therefrom.

In the illustrated embodiment, the mutually distanced latching or stop elements 29, 30 formed by projections 36, which of at least one inner boundary surface of the shaft 20 protrude. Of course, it is also possible, such projections 36, which form latching lugs for secure positioning of the carrying device 5, to provide near or directly to the front end portions of the shaft 20 and thereby the projections 36 in the form of locking lips form, which in the direction of the longitudinal central axis of the shaft 20.

The mutually distanced latching or stop elements 29, 30 or holding devices 31, 32 may instead of the arrangement on inner boundary surfaces of the shaft 20th also be formed on the support device 5 for the ink pad 4. It is also possible the mutually distanced latching or stop elements 29, 30 to Bewerkigung the resiliently secured working or use position 33 and replacement or Maintenance position 32, both in the interior and in the front end of the shaft 20, as well as on one of the surfaces of the support device 5 form. This can be done in Inner and / or in the front end regions of the shaft 20 and at respectively associated Surface regions of the support device 5 mutually corresponding projections 36 and the recesses 37 may be formed. These quasi double sided protrusions 36 and recesses 37 can thereby have an improved latching or positioning effect for the support device 5 with the ink pad 4 with respect to the receiving device 23rd or with respect to its shaft 20 effect.

Especially when the support device 5 with the ink pad 4 exclusively by a Side or wall surface 21 or 22 are inserted or withdrawn into the shaft 20 can, it is sufficient, on the support device 5 or in the shaft 20 only a detent recess or merely to arrange a locking projection, which with two mutually distanced Latching or stop elements 29, 30 in the form of projections 36 and / or depressions 37 interacts.

Between the individual predefined positions of the stamp pad 4, in particular between the working or use position 33 and the replacement or maintenance position 34, the support device 5 with the ink pad 4 relative to the shaft 20 also be freely adjustable. Instead of training own locking or stop elements 30th in the replacement or maintenance position 34, it is understood in the context of the invention also possible, only one can be overcome by additional force if necessary Provide stop limit. This stop limit is designed such that an automatic falling out of the support device 5 together with the ink pad 4 from the shaft 20 is prevented when the support device 5 from the working or use position 33 was pressed. Subsequently, then the support device 5 with the ink pad 4 freely movable in a section between the working or use position 33 and the replacement or maintenance position 34 slide back and forth. A total fall out the support device 5 is, however, by the additional locking or stop element 30 and the further holding device 32 in a front end region of the shaft 20 or prevented in an end region of the support device 5.

At least one of the locking or stop elements 29, 30 is designed such that a kind of locking coupling is formed, which can build up such a holding force that the Carrying device 5 is positioned at least positioned in the working or use position 33 can be and by applying a compressive force, for example via a finger of the user or via a separate actuator, relative to the shaft 20 moves and in the Replacement or maintenance position 34 can be transferred. The elastically yielding and restoring movement of the locking or stop elements 29, 30 can thereby by the Elastic properties of the projections 36 and recesses 37 themselves or by resilient compliant and resiliently mounted projections 36 and recesses 37, for example on spring-mounted tongues, be implemented.

In Fig. 4, another embodiment and arrangement of a receiving device 23 and a lower part 3 for an inventively designed stamp with each other distanced Holding devices 31, 32 or latching or stop elements 29, 30 on a support device 5 of an ink pad 4 and / or on or in a shaft 20 as needed replaceable recording of an example cuboid support device 5 illustrated. For the sake of simplicity, only the lower part 3 or the receiving device was here 23 of an inventively designed punch shown.

Here, in the end-side end regions or lateral wall regions of the cuboid Support body 5 each two formed as wells 37, in the off or insertion direction - According to arrow 28 - mutually distanced latching or stop elements 29, 30 are formed. These locking or stop elements 29 and 30 are in the inserted position or in the working position of the support device 5 with corresponding locking or stop elements 29 and 30 in positive, by applying correspondingly high pressure forces as needed detachable connection. Here are on lateral boundary surfaces of the Shaft 20 designed in the manner of locking lugs locking or stop elements 29, 30 are provided and at the front, opposite end portions of the support device 5 formed the opposite locking recesses. Of course, the reverse or Inverse arrangement of the detent recesses or locking projections also possible.

It is also conceivable, either on the support device 5 or in or around the shaft 20th merely provide a latching or stop element 29 or 30, which in dependence the taking of the replacement or maintenance position optionally with one of the two to each other distanced latching or stop elements 29, 30 is in communication.

The decoupling or solution of the locking connection between a projection 36 and a Recess 37 or another trained coupling device can on the one hand by the elastic compliance of the material of the locking or stop elements 29, 30 itself, in particular by its elasticity or by relative to the receiving device 23rd or relative to the support body 5 adjustably mounted latching or stop elements 29, 30 achieved become. For the relative adjustment of a latching or stop elements 29, 30, in particular a wart-like elevation or a projection 36, it is conceivable in the peripheral region slit-shaped openings in the plastic material provide that a resilient mounting the projections 36 in the transverse direction to the insertion or insertion direction - according to arrow 28th - Allow the support device 5. The projections 36 are thus resilient mounted latching or retaining tongues for the support device 5 is arranged. It is also possible Wall regions on which the projections 36 or depressions 37 are arranged are elastic compliant to dimension and so a certain bias for an optional to achieve activatable and deactivatable locking.

In the illustrated embodiment is advantageous that the support device 5 with the Stamp pad 4, starting from both sides or wall surfaces 21, 22 in the shaft 20th inserted or can be pulled out of the shaft if necessary. The carrying device 5 with the ink pad 4 is thus accessible from both sides of the stamp. This On the one hand achieved by the fact that the shaft 20 as a breakthrough with over the length or Depth of the shaft 20 is formed substantially constant cross-section.

In Fig. 5 is another embodiment for building a snap or locking connection and for limit stop limit of a support device 5 with respect to a receiving shaft in a stamp illustrated. This is on opposite side walls of the support device 5 arranged for the ink pad each have a latching or stop element 29, which position the support device 5 in the working position and with a certain holding force Secure in the appropriate receiving shaft. These locking or stop elements 29 are in the central region of the side walls or end faces of the hood-like support device 5 arranged. In a distanced end or edge area of this side or end walls of the support device 5 is further each one as Endbegrenzungsanschlag trained latching or stop element 30 is formed. This catch or stop element 30 prevents a complete sliding out of the support device 5 with the ink pad. 4 from the associated receiving shaft. Only by applying a sufficiently high extraction rate or tensile force can then the support device 5 preferably also entirely from the stamp or the respective lower part are removed.

This is in particular by a special design of the outer, lateral wall surfaces the pad holder or the support device 5 is a determination or positioning of the support device 5 achieved at least in the working position of the stamp pad 4. By front side Pressure on the support device 5 or the cushion holder can be forced this to move over on the housing or insertion slot formed latching noses. This Uncoupling or coupling process can be achieved by inclined surfaces on the locking lugs or locking recesses are facilitated or favored. Mutually assigned latching noses and detent recesses on the support device 5 and within the receiving shaft are preferably in elastic bias to each other to play as possible and secure positioning or holder to achieve. The complete falling out of the carrying device 5 with the ink pad is prevented in any case that in at least one End region of at least one side wall a step-shaped projecting latching or stop element 30 is formed.

To the least possible movement of the support device 5 in a section between two mutually distanced holding devices 31, 32 to achieve without disturbing acting adjusting resistance, so-called exemptions 38 or the appropriate Material recesses be formed. Such exemptions 38 are preferred between two mutually distanced latching or stop elements 29, 30 are provided. These exemptions 38 can be formed on the side walls of the support device 5 be and cause, for example, locking lugs or projections 36 at one of the shaft 20 limiting inner surface not at all or only relatively slightly with the support device 5 are in contact or frictional connection. Even with the reverse Arrangement of the projections 36 and recesses 37 between the support device 5 and the Receiving device 23 and the shaft 20 can such exemptions 38 are formed become.

As can be seen further from FIG. 5, they can be distributed over the ejection or insertion direction. according to arrow 28 - also several, in particular three, mutually distanced holding devices 31, 32 or latching or stop elements 29, 30 may be formed. In particular, here are in the corner or edge regions of the support device 5 each acting as an end stop Detent or stop elements 30 formed. In the middle area between the two Latching or stop elements 30, the further latching or stop element 29 is arranged, which secures or positions the carrying device 5 in its working or use position 33 supports. Thus, in this embodiment, there are basically two interchangeable or maintenance positions 34 and a defined working or use position 33 for the Carrying device 5 and the ink pad 4th

Preferably, the support device 5 is formed symmetrically to its longitudinal plane of symmetry 39. That arranged in the edge or corner regions of the cuboid support 5, acting as end stops locking or stop elements 30 are in the respective same distance to the centrally arranged latching or stop element 29, which is the working or use position 33 of the support device 5 defines placed.

Alternative arrangements and / or placements of the locking or stop elements 29, 30th or the proper holding devices 31, 32 to ensure a defined working position and to ensure that the carrying device 5 after leaving the position secured Working or use position 33 is not unhindered from the receiving shaft fall out, are within the skill of the art. Especially a number of modifications are possible without departing from the scope of the invention.

FIGS. 6 to 8 show an advantageous development of the previously described stamp 1 illustrates.

The structure of this stamp 1 corresponds substantially to the previous description and thus the same reference numerals are used for the same parts. previous Descriptions are therefore mutatis mutandis to like parts with the same reference numerals transferable.

In particular, a aufzusetzendes to be stamped pad is also in this embodiment Lower part 3 is provided, the upper edge region at least partially from a cap or hood-like upper part 2 is surrounded. The upper part 2, which at the same time the actuator 9 for the punch 1 forms or includes, is against the force the spring 14 relative to the lower part 3 adjustable. For telescopic telescoping the upper part 2 and the lower part 3, the pressure plate carrier 8 from the ink pad 4 moves towards the pad and doing the desired stamping on the pad produced.

Here, too, the soft-elastic ink pad 4 is in a relatively dimensionally stable Carrying device 5 is supported. The carrying device 5 with the ink-impregnated therein Ink pad 4 is in the appropriately sized slot 20 of the stamp. 1 can be used and if necessary by a user, for example, interchangeable for maintenance purposes or soakable. In this case, the support device 5 with the ink pad 4 at least partially withdraw from the shaft 20 to make the ink pad 4 accessible.

To facilitate the handling of the stamp 1 for control or replacement purposes, is on the support device 5 for the ink pad 4 at least one adjustably mounted handle 40 trained.

According to a preferred embodiment, this handle 40 is in the manner of a tab 41st formed, which is pivotally connected to the support device 5 and optionally between a rest position - Fig. 7 - and a working position - Fig. 6 or Fig. 8 - adjusted or can be pivoted. The preferably pivotable or articulated connection between the handle 40 and the frame-like support device 5 for the ink pad 4 is preferably implemented by means of a so-called film hinge 42. Such a thing Film hinge 42 is by a relatively thin-walled material transition from the tab 41 and the proper handle 40 to the actual support device 5 realized. The handle 40 is integrally connected to the support device 5 and this one-piece design with the intermediate film hinge 42, preferably by an injection molding process produced. Optionally, the plastic from which the carrying device 5 and the handle 40 are formed, compressed in the region of the film hinge 42 to a high strength of the film hinge 42 and a stable connection between the tab-like handle 40 and the support device 5 to achieve.

Preferably, the handle 40 is folded up according to arrow 43 to the handle 40 of be able to transfer the rest position into the working or active position. It is advantageous that a carelessly positioned handle 40 does not hinder a stamping process can, because by the depression of the upper part 2 one in the active or working position located handle 40 forcibly pivoted to the rest position or closer to the rest position becomes. It is also favorable, the handle 40 or tab 41 in the lower edge or edge region of the cuboid support device 5 form.

Optionally, the tab-like handle 40 in its rest position - Fig. 7 - by a Locking or fixing device not shown secured. As best of Fig. 6 it can be seen, in the lower part 3, a recessed grip 44 may be formed which gripping the tab 41 and the transfer of the same from the rest position to the active or Working position easier.

In the active or working position of the handle 40 - Fig. 6 - is mainly a pulling out the support device 5 together with the ink pad 4 easier because a larger attack or holding surface is present and the force can be optimally executed. These Handle 40 is as pulling or pulling member for the support device 5 relative to the Shaft 20 and the receiving device 23 is provided. Of course it is also possible the ink pad 4 or support device 5 via this handle 40 from the stamp push out and thus use the handle 40 as a thrust member.

It is advantageous, the tab 41 and the proper handle 40 after their use by means not shown fixing or locking devices in the rest position or in set the recessed grip 44 and thus an unwanted pivoting or adjustment to prevent it.

Instead of forming a lug 41 pivotable about a horizontal axis, it is Of course, also possible, the handle 40 pivotable about a vertically oriented axis to store. Preferably, a film hinge 42 is always formed to a cost-effective Production of the support device 5 and the stamp pad 4 to achieve.

Alternatively to the formation of a handle 40, it is also conceivable in the wall regions of Carrying device 5 handle recesses or draw slots form. In some circumstances, however the space available for the ink pad 4 is thereby somewhat reduced and is Furthermore, the handling compared to a swing out or fold out handle 40 worse. The formation of at least one sprayed onto the support device 5 handle 40 or tab 41 is in terms of handling for a change or a check the stamp pad 4 particularly advantageous. The connection of the handle 40 with the support device 5 via the film hinge 42 allows a cost-effective production and a relatively problem-free production.

In the embodiment according to FIGS. 6 to 8, the lower edge of the upper part 2 or of the actuating element is 9 in the area of the front and back of the punch 1 set back or recessed to the insertion or withdrawal of the support device 5 relative to the To enable shaft 20 when the punch 1 in the rest position shown in Figs. 6 to 8 is present. In the region of the narrow sides 26, 27 of the punch 1, however, extends the upper part 2 and the actuating element 9 to below the lower edge of the shaft 20th As a result, the largest possible grip surface is provided and the basis for created an ergonomic operation of the stamp 1. These recesses 45 or cuts in the lower edge region of the upper part 2 and the actuating element 9 are such dimensioned that the support device 5 easily inserted into the shaft 20 and from it can be removed when the punch 1 assumes the initial or rest position or by means of the locking device 17 in the defined for the pillow change maintenance or Feststellage present.

In Figs. 9 and 10 is another embodiment for facilitating the change or the control of a used stamp pad 4 shown. This is in contrast to the previous one described strap solution, which is mainly used as a traction device, a Ausdrücklösung for the ink pad 4 together with the support device 5 from a corresponding Receiving shaft of the punch 20 proposed.

The basic structure of the stamp 1 corresponds to the previous one already described Structure, so that the previous descriptions apply mutatis mutandis to the same parts are transferable with the same reference numerals.

Here, the upper part 2 or the actuating element 9 or another element of the Upper part 3, such as a transparent window, a text window or a rubberized Grip area 46, on the front side 47 of the stamp 1 on the support device 5 and the Drawn ink pad 4, so that this at least partially covered by the upper part 2 or is covered. In particular, a lower edge of the hood or cap-like upper part extends 2 and actuating element 9 to below the bottom 6 of the stamp pad 4th or its supporting device 5. The upper part 2 or the actuating element 9 for the stamp 1 thus extends relatively far in the direction of the footprint 12 of the punch 1, so that a relatively large-scale and thus ergonomically shaped handle area or operating area is achievable. On the back 48 of the punch 1 is in turn a recess 45th or a corresponding incision in the cap-like upper part 2 formed around the ink pad 4 if necessary to be able to remove from the shaft 20, without the cap-like Upper part 2 to be disabled.

On the front side 47 of the stamp 1, in particular in the cap-like upper part 2 of the stamp 1 is at the front thereof designed as a pusher 49 handle 40 for ejecting or pushing out the support device 5 is formed. This pusher element 49 can be designed in the form of an independent push button 50, which in a corresponding Recess 51 of the upper part 2 and the actuating element 9 used in such a way is that the push button 50 with respect to the surrounding edge regions of the cap-like Upper part is relatively movable. Especially when pressure is applied to the pusher element 49, this is parallel to the guideway of the shaft 20 and parallel to the extension direction - According to arrow 52 - the support device 5 relative to the shaft 20 adjustable. Instead of a direct force on the support device 5 is here so a indirect power transmission, in particular pressure transmission, on the support device 5 for implemented the ink pad 4.

To at least slightly issue or eject the carrying device 5 from the shaft 20 To be able to, is designed as a push button 50 handle 40 with the support device 5 in To bring cover. For this purpose, the actuating element 9 is slightly in the direction of the footprint 12 to move and either to hold manually or via the locking device 17 to lock. By front-side pressure on the pusher element 49 and the Push button 50 this is moved in the direction of the guideway in the shaft 20 and the Carrying device 5 at least slightly from the receiving device 23 and from the Lower part 3 pushed out or ejected.

To avoid the complete sliding out of the ink pad 4 and the support device 5 out of the shaft 20, the previously described holding device 32 in Art be formed by locking or stop elements 30.

If the push button 50 is formed as an independent component, this is for example held by a flexible tongue within the recess 51 and relative to the depth the recess 51 in the actuator 9 and upper part 2 adjustable.

As can be seen from FIGS. 11 and 12, the handle formed as a pusher element 49 40 for ejecting or slightly pushing out of the ink pad 4 from the receiving shaft also by an integral with the upper part 3 and the actuating element 9 or a stamp cover 53 formed element may be formed. Especially is here by the elastically yielding properties of the stamp cover 53rd or the demgemäßen upper part 2, a portion which the handle 40 and the push button 50 form, elastically yielding and restoring trained. This can be, for example by means of a curved push-button 40, which surrounds all around by a bead 54 is to be accomplished. It is advantageous that for the handle 40 is not structurally independent Element is required and in the manufacturing process, especially during a Injection molding process, such a push button 50 can be made effzient.

In particular, when the stamp cover 53 and the cover for the stamp from a elastomeric plastic is made, you can this stamp cover 53 with the integral Use push button 50 as a handle 40 for ejecting an ink pad. At the same time by the elastomeric, for example, rubbery, handle portion of the punch whose handling favored.

FIGS. 13 to 15 show an embodiment for facilitating an improved control or exchange process of the stamp pad 4 of a stamp 1 or with respect to the receiving device 23 illustrates the support device 5 of an ink pad 4.

Here, the support device 5 on a component 55, in particular on a wall part 56th the stamp 1 and the receiving device 23 attached. This attachment can be either detachably, for example by means of the schematically indicated coupling device 57, or even insoluble by a one-piece design of the support device 5 and the Be executed wall portion 56.

The respective component 55 of the stamp 1 takes in comparison to the side surfaces of the essentially cuboid support device 5 relatively large areas of the outer surfaces of the stamp 1. In particular, the component 55 or the wall portion 56 is a relative extensive, easy and safe to grasp handle 40 for simplified manipulation of the Stamp 1 when pulling out or inserting the ink pad 4 opposite the shaft 20 represent. The component 55 or wall portion 56 thus provides a quasi an extended handle 40 for the support device 5 and the ink pad 4 is.

Preferably, the component 55 via guide and / or fixing elements 58 with the receiving device 23 coupling or connectable and solvable if necessary. This leadership and / or fixing elements 58 may be any of those known in the art Latching or snap connections on the component 55 and thus corresponding or equivalent Connecting elements formed on the receiving device 23 and the punch housing be.

Alternatively or in combination, it is also possible, based on the previously described, positively engaged with each other holding devices 31, 32 - see, for example Fig. 1 to 3 - on the support device 5 and the punch housing the desired positioning and mounting the support device 5 together with the component 55 relative to the receiving frame 23 to achieve. The component 55 of the punch connected to the carrying device 5 1 or the receiving device 23 may, for example, one of the outer wall surfaces 21 of the receiving device 23 and the corresponding stamp 1 represent. Possibly the component 55 may also comprise a so-called Aufsetzrahmen 59, with which the stamp 1 is placed on the pad to be stamped.

Preferably, the component 55 protrudes substantially at right angles to the bottom 6 of the block-shaped Carrying device 5 and the block-shaped ink pad 4 before. This component 55 closes substantially flush with one of the side surfaces of the approximately cuboidal Carrying device 5 from, so that a cross-sectionally substantially L-shaped Stamp component results.

In addition, in this embodiment, the previously described detent or stop elements 29, 30 - see Fig. 1 to 3 - for secure positioning or end limitation the displacement movement of the support device 5 together with the component 55 opposite the receiving device 23 are used.

An advantage of this embodiment is that the ink pad 4 and their support device 5 by the operator does not have to be taken in the immediate vicinity, but a kind extended, in itself rigidly or immovably connected to the support device 5, safe to be gripped handle 40 is present, with the risk of contamination of the fingers or Clothes of the operator in a manipulation of the ink pad 4 can be reduced. It is also possible, a better tangibility of the occasionally relatively small ink pad 4 to achieve and thus a secure even with relatively clumsy handling Removing or effortless insertion of the ink pad 4 in the receiving device 23rd to achieve.

By forming a coupling device 57, it is necessary replacement the stamp pad 4 optionally allows either the support device 5 together with the Stamp pad 4 and the component 55 to replace or only the support device 5 included to dispose of the ink pad 4. The latter is particularly recommended if the Component 55 is relatively large area and expensive. For such cases is between support device 5 and the component 55, the coupling device 57 is formed, which preferably in Type of a tool-operated, latching or positive connection between These parts may be designed, as can be seen above all from FIGS. 14, 15. For example This may be coupling device 57 in the manner of a dovetail connection be realized.

FIG. 16 illustrates a somewhat different embodiment of the embodiment according to FIG. 5.

Here, the first latching or stop element 29 of the holding device 31 for position-secured Holding the support 5 receiving a stamp pad 4 in the working or use position 33 approximately in the middle portion of an entire guide length 60th of the shaft 20 is arranged. That the locking or stop elements 29 are approximately in the central region the total depth of the shaft 20 is placed. Preferably, two locking or stop elements 29 on opposite, lateral inner surfaces 61, 62 of the shaft 20th educated.

The spaced apart, further holding device 32, in particular their latching or stop elements 30 are here at the upper inner surface 63, i. at the upper boundary surface arranged in the shaft 20 and thereby in at least one end region 64, 65 of the Shaft 20 is provided. These latching or stop elements 30 for defining the replacement or maintenance position 34 for the support device 5 are preferably by wart-like Projections-36 formed, which provided in the receiving device 5 for the support Shaft 20 protrude. Referring to the entire guide length 60 of the shaft 20 are the other locking or stop elements 30 of the first or central locking or Stop elements 29 spaced by a distance 66, which is approximately half the guide length 60 corresponds.

These further, wart-shaped latching or stop elements 30 protrude in at least a, preferably formed in two on an upper surface 68 of the support device 5 guide grooves 67. These groove-like guide grooves 67 extend over the entire depth the support device 5, which corresponds approximately to the guide length 60 of the shaft 20. In approximately in the middle region of these guide grooves 67 is in each case at least one wart-shaped elevation 69 formed, which in cooperation with the locking or stop elements 30 on the receiving device 23 a limit stop for the support device. 5 during the adjustment of the working or use position 33 in the opposite to the Receiving device 23 or the shaft 20 projecting replacement or maintenance position 34 represents.

That In this embodiment, the latching or stop elements 29 and 30 of the crate or hood-like support device 5 for the ink pad 4 in the longitudinal plane of symmetry 39 of the support device 5 placed. Instead of the pairwise arrangement, it goes without saying also possible to provide only one locking or stop element 29, 30 or a plurality of corresponding latching or stop elements 29, 30 form. About that In addition, it is also conceivable that placed on the lateral inner surfaces 61, 62 of the shaft 20 Latching or stop elements 29 to the upper inner surface 63 of the shaft 20 to embarrassed.

With the described embodiment is achieved that the support device 5 with the ink pad 4 is held exactly and reliably in the working or use position 33 and while the support device 5 largely flush with the outer surfaces of the receiving device 23 completes. For a change or maintenance of the ink pad 5 is only exert sufficient pressure on an exposed side surface of the support device 5, so that they are in about half the guide length 60 and approximately at the distance 66th from the receiving device 23 and its shaft 20 emerges. In this partially extended Position of the support device 5 relative to the receiving device 23 is then the Carrying device 5 before a total or unwanted or a misbehaving Falling out of the shaft 20 secured by the further holding device 32 with the Latching or stop elements 30 is active. In this partially extended, however, before a position completely safe falling out then the support device 5 can safely be taken without touching the ink pad 4. Only by applying a defined removal force, for example, by conscious, manual pulling or pressing on the support device 5, then the support device 5 together with the ink soaked Stamp pad 4 wholly and safely removed from the receiving device 23.

Also in this embodiment is therefore a total or surprising falling out the stamp pad 4 prevents when e.g. accidentally or inadvertently on an in the shaft 20 inserted support device 5 is acted upon. With this embodiment can thus be prevented in an advantageous manner that the ink pad 4 after overcoming the holding device 31 to secure the working or use position 33 slides directly or wholly out of the shaft 20, while the floor, on the table or on clothing, causing stubborn dirt.

The support device 5 for a provided with stamp ink stamp pad 4 can, as schematically shown, be formed cuboid. Especially in dependence of the to be generated Stempelabdruckes, the support device 5 and the ink pad 4 and / or Receiving device 23 in plan view also round or polygonal, for example, circular, have elliptical, triangular, polygonal, or contour outlines composed thereof.

For the sake of order, it should be pointed out that for a better understanding of the Structure of the receiving device 23 and the stamp 1 whose components partially unmaßstäblich and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can the description be removed.

18. Stamp (1) of the self-inking type, with a bottom part (3) which can be extracted onto the surface to be stamped and a top part (2) which can be displaced against the return force of a spring (14) relative to the bottom part (3), as well as a turning and displacement mechanism (13) coupled with the top part (2) in displacement for a stamp plate (7) disposed in the bottom part (3) in order to move it backwards and forwards between a stamp pad (4) and a surface to be stamped, which stamp pad (4) is at least partially accommodated in a relatively dimensionally stable frame-type or cap-type support device (5) and secured in its operating or usage position (33) by means of a retaining device (31), for example in the manner of a catch or snap-fit connection, characterised in that a grip (40) is provided, by means of which the support device (5) can be transferred at least from the secured operating or usage position (33) into a replacement or maintenance position (34) or at least into a position uncoupled from the holding device (31).
19. Stamp as claimed in claim 18, characterised in that the grip (40) is mounted on the support device (5) so as to be displaceable and can be moved between a non-operating position and an active or operating position as and when necessary.
20. Stamp as claimed in claim 18 or 19, characterised in that the grip (40) is pivotably connected to the support device (5) by means of a so-called film hinge (42).
21. Stamp as claimed in one of claims 18 to 20, characterised in that when the grip (40) is in the active or operating position, a force acting on the support device (5) is enhanced or facilitated and, when the grip (40) is in the non-operating position, the support device (5) is locked or prevented from moving relative to the stamp (1).
22. Stamp as claimed in one of claims 18 to 21, characterised in that the grip (40) is provided in the form of a tab (41) integrally formed on the support device (5) which can be pivoted upwards about a horizontally extending pivot axis into the active or operating position as indicated by arrow (43).
23. Stamp as claimed in one of claims 18 to 22, characterised in that the grip (40) is secured in its non-operating position by means of a lock or snap-fit mechanism.
24. Stamp as claimed in claim 18, characterised in that the bottom peripheral region of the top part (2) overlaps the support device (5) either at the front face or at the rear face (47; 48) and the grip (40) is provided on the top part (2).
25. Stamp as claimed in claim 18 or 24, characterised in that the grip (40) is provided in the form of a push button (50) in a recess (51) of the top part (2) and is mounted so as to be displaceable in the extraction or insertion direction - arrow (28) - of the support device (5) relative to its housing shaft.
26. Stamp as claimed in one of claims 18, 24, 25, characterised in that the grip (40) is provided in the form of a pusher element (49) integrally formed with the top part (2).
27. Stamp as claimed in claim 26, characterised in that the pusher element (40) is provided in the form of an elastically flexible and resilient region in a portion of the top part (2) co-operating with the support device (5).
28. Stamp as claimed in one of claims 18, 24 to 27, characterised in that at least the portion of the top part (2) co-operating with the support device (5) is made from elastomeric plastic.
29. Stamp as claimed in claim 26, characterised in that the pusher element (49) is provided in the form of a bead-like indentation in the top part (2) or in a stamp cover (53) secured to the top part (2).
30. Stamp as claimed in claim 26, characterised in that the pusher element (49) is provided in the form of at least one slot-shaped orifice in a portion of the top part (2) co-operating with the support device (5).
31. Stamp as claimed in one of claims 18 to 30, characterised in that the grip (40) is positioned ready for use relative to the support device (5) with an active securing device (17) or in a defined relative position between the top part (2) and the bottom part (3).
32. Holding unit as claimed in claim 5, characterised in that the first catch or stop element (29) for securing the operating or usage position (33) is disposed in the middle region of a guide length (60) of the shaft (20) and the other catch or stop element (30) spaced apart from it for defining the replacement or maintenance position (34) is disposed in at least one end face region (64, 65) of the shaft (20), preferably on a top internal face (63) of the shaft (20).
33. Holding unit as claimed in claim 32, characterised in that the at least one other or front face catch or stop element (30) in the shaft (20) is provided in the form of at least one wart-like projection (36) designed to engage in a channel-shaped guide grove (67) on a top face (68) of a support device (5) for a stamp pad (4) which can be inserted in the shaft (20).
34. Holding unit as claimed in claim 33, characterised in that at least one wart-like raised area (69) is provided in a middle portion of the guide groove (67) on a support device (5) which can be accommodated by the shaft (20) and, in co-operation with the catch or stop element (30) on the shaft (20), forms a restriction stop which can be manually overcome by pulling or pushing on the support device (5) in order to extract the support device (5) starting from the operating or usage position (33) into the replacement or maintenance position (34) spaced apart from it.
35. Holding unit as claimed in one of claims 32 to 34, characterised in that two mutually spaced catch or stop elements (30) are provided on the top internal face (63) of the shaft (20) extending transversely to the guide length (60) of the shaft (20).
