Description

The invention relates to a self-inking stamp according to the introductory part of claim 1.

Selbstfärbestempel with so-called Oberschlagfärbung in which a stamp assembly is moved in a stamp housing by means of a turning mechanism from an upper Einfärbestellung in a lower impression position, have long been well known. The turning and downward movement of the punch assembly is here called by means of an operating part, here called operating bow, accomplished, which can be moved relative to the punch housing from a rest position to an operating position vertically from and to. The actuating bow has at least two opposing lateral limbs, with which the punch unit, also called punch plate unit, is rotatably coupled via an axle or over cantilever journals, the axle journals or the axle through a longitudinal slot in the punch housing from within the die housing, from there provided stamp assembly, projecting to the outside operating bracket.

A double arrangement of comparable punch units, but without turning mechanism, is from the WO 2004/091923 A1 known.

In self-inking stamps, it is also known to attach an impression sheet to the top of the actuating part or strap as information relating to the producible stamp impression, for which purpose an at least partially transparent viewing window is attached to the actuating clip above this impression leaf, cf. eg AT 3176 U1 , but also EP 1 603 754 B1 . US 2007/0169650 A1 . WO 01/83227 A1 or WO 2005/037565 A1 , As here in particular from the AT 3176 U1 can be seen, the curved impression sheet inside the viewing window part, hereafter called the window part, fixed in the manner of a snap above inwardly projecting projections of the window part, after which the window part is locked together with the impression sheet on the actuating part using just these projections.

In the case of the self-inking stamp according to WO 2005/037565 A1 (but also US 2007/0169650 A1 ) is the window part at two each other opposite sides of the actuating member with downwardly extending, provided on this operating part walls, so as to optionally within the window part a larger impression sheet, possibly with additional information about the holder of the stamp to accommodate.

In general, however, ends the window portion in the upper rest position of the operating part or strap in which the receiving space or shaft for a ink pad container with ink pads is accessible from the outside, above this receiving space or bay, so used in this rest position of the ink pad container in the receiving space or can be removed from this, such as to soak the ink pad with ink or to ever swap the ink pad container. In these known Selbstfärbestempeln thus the window part on the operating part is indeed solvable, but fixed, i. immovable, appropriate. The window part accordingly forms in the known self-inking a practically fixed part of the actuating bracket.

It has been found in these known self-inking stamps that located in the receiving space of the stamp housing ink pad with the ink or ink pad is sometimes unintentionally pushed out of the receiving space at least partially, with an unwanted coloring of fingers or even soiling of other objects may be the result , It is also conceivable that the ink pad container in said rest position shifts slightly out of its receiving space and thereby hinders a downward movement of the actuating bracket relative to the punch housing when a stamp imprint is to be made. It must then be pushed back the color pad container in the proper position within the receiving space so that afterwards the desired impression can be made.

It is also known in similar Selbstfärbestempeln, such as according to AT 507833 A2 or US 5 743 186 A , the orifices or slots for the ink pad container in the upper rest position of the actuating member relative to the punch housing to each other to be arranged offset, so that for the extension or insertion of the ink pad container, a relative displacement of operating part and punch housing must be made. However, this is troublesome to handle.

In other known self-inking temples, approximately according to WO 2006/119597 A2 or EP 803 372 B1 ( DE 696 01 069 T2 ), an upper, latched lid part of the operating part must first be removed so that the ink pad container can be inserted or removed; This is relatively expensive to produce and cumbersome in operation.

When self-inking stamp according to the already mentioned above WO 01/83227 A1 is a transparent hood part which concealed in the upper normal or rest position of the operating part with an extension of the receiving slot for ink pad container on the stamp face, pivotally mounted on the actuating part on the rear side, so that the receiving slot for the ink pad container at the front of the stamp by Pivoting the hood part can be accessible. The pivotal mounting of the hood part is relatively expensive to manufacture, the accuracy of the positioning of the hood part in the closed position is difficult to achieve and, moreover, the pivot bearing is unreliable in operation and breaks easily.

The invention now seeks to remedy this situation and therefore has the task of proposing a self-inking as mentioned at the beginning, in which an accidental or accidental pushing out, albeit only partially, the ink pad container from its receiving space in the rest position of the punch reliably prevented by simple means can be so as to avoid the described obstruction or risk of contamination in an at least partially projecting ink pad container.

Accordingly, the self-inking stamp is characterized according to the invention by the features defined in the characterizing part of claim 1.

In the present self-inking stamp, below also briefly Stamp, thus the window part relative to the operating handle can be moved vertically, wherein it covers in the lower position, the normal position, the mouths of the receiving space for the ink pad container (if provided on two opposite sides of the stamp receiving space mouths), even if the operating handle in its upper resting position or coloring position. The window part is thus always moved together with the operating handle, when stamp impressions are produced and then the stamp is moved back to its respective rest or Stempeleinfärbestellung. However, if the ink pad container to be pushed out of its receiving space, such as for the purpose of changing or soaking with ink (stamping ink), the window part is pushed up relative to the operating handle, so that he then access to the ink pad container - on at least one side - allows.

It is particularly advantageous if at least one wall of the window part has an abutment or snap element which comes to rest on the actuating bar when the window part is pushed up relative to the actuating bar on a stop or snap connection part formed, for example, by a wall recess. By this stop or snap connection elements or parts, the movement of the window part is limited relative to the operating bracket upwards, so that the window part is not unintentionally deported entirely from the operating bracket. Of course, however, this stop or this snap or locking connection can also be overcome, for example by slight bending out of the at least one wall of the window part, so as to remove the window part completely from the operating handle, such as when access to the top of the actual operating bracket, eg for inserting an impression card, is desired.

On the other hand, it is particularly advantageous if at least one wall of the window part, preferably at the free lower end, a locking element is provided which can be locked in the mounted position with a corresponding locking part on the operating bracket or preferably on a separate frame member coupled to the operating bracket , In this way, the entrainment of the window part with the operating handle, possibly via the interposed frame member, i. common movement of the window part and operating handle for the normal case, secured.

In view of the simplest possible training, it is also advantageous if the stop element at the same time forms the locking element. In itself, however, it would of course also conceivable to provide stop element and locking element separated from each other.

In the present self-inking stamp with the relative to the operating handle vertically adjustable window part, it is further expedient if - instead of inside the window part - an impression card holder is provided on an upper web of the operating handle. In this way, an impression card is attached directly to the operating handle, at the top, on the upper bridge, which reproduces the respective cliché and so conveys the imprint important for stamping information. The upper web of the actuating bracket can be as well as the upper web of the window part as known from the prior art convex curved, but it is in the present stamp in a simple manner, in view of the most economical production and convenient operation of the punch, also possible , the upper webs of the operating bracket and window part flat, and in particular also perpendicular to the side walls of the window part and confirmation bracket to provide.

It is here further favorable if the impression card recording with lateral, an impression card cross-holding projections is provided. The aforementioned holding projections can be formed in the form of simple, optionally interrupted bars on the edge of the impression card holder. It is possible to insert the impression card when pushed up into an intermediate position window part of the length of the page in their recording or postpone it.

The window part with its comparatively large wall surfaces on opposite sides further offers a particularly advantageous possibility of attaching a sheet for further information, and it is accordingly advantageous if a receptacle for an information sheet is provided within the window part, wherein preferably boundaries for the support of the For example, in the cross section also U-shaped information sheet on the outside of the actuating bracket or preferably provided on the inside of the window part. The information sheet can also be viewed or read by the window part walls, which are at least transparent in this area, and it is possible, for example, to provide the most diverse information, such as the owner of the stamp, possibly with a photograph of the stamp owner; Also, the information sheet can be designed in special colors, so as to give the stamp a special look overall. The information sheet is also referred to below as an image card.

Nonetheless, in order to enable an insight into the impression card located at the top of the stamp, the information sheet, which in a comparable manner, similar to the window portion, has a U-shaped cross-section, has a recess in its upper web, through which the impression card is visible is.

With regard to an advantageous multiple use, it is then favorable if the stop element on the window part at the same time forms one of the limits for the information sheet.

Furthermore, it is advantageous if the window part on two open end faces of its walls inwardly projecting, preferably having strip-shaped projections as boundaries for the information sheet.

In Fig. 1 is shown a self-inking stamp 1 in its normal rest position, in which a on a stamp housing 2 above attached actuating bracket 3 assumes its upper position. On this operating bracket 3 is outside a cross-sectional shape of a reverse U exhibiting window part 4 is attached, see. except Fig. 1 also Fig. 2 . 2A and 3 , wherein this window part 4 is vertically displaceable relative to the actuating bow or part 3, and that in a first stop position, the in Fig. 2 2A, and in which, for example, an exchange (insertion or removal) of a ink pad container 5 is possible, this change in Fig. 2A shown in particular. In the normal position, as in Fig. 1 However, the window part 4 covers the ink pad container 5 or generally the receiving space 6 for this ink pad container 5. However, the operating handle 3 conceals in its upper rest position, as from the Fig. 2 . 2A and 3 Immediately apparent, the receiving space 6 not, ie he leaves him free. For changing the ink pad container 5 can then, for example, as from Fig. 2A can be seen, a separate guide member or receptacle 7 are attached to the stamp housing 2 in the region of the opening or mouth of the receiving space 6, wherein the ink pad container 5 of this guide receptacle 7 in the receiving space 6 in the stamp housing 2 into or out of this on the Guide receptacle 7 can be pushed. However, this technique of changing the ink pad container 5 is not the subject of the present invention and thus will not be further explained.

With the operating handle 3, a separate lower frame part 8 is connected in the operating position. This frame part 8 is, as in the following mainly with reference to FIGS. 7 and 7A even closer is explained, normally locked with the operating bracket 3 on the narrow sides of the punch 1.

At the two broad sides of the cross-section example rectangular punch 1 of the window part 4 is locked with this frame part 8 when the punch 1 in the normal position according to Fig. 1 located. This locking will be described in more detail below with reference to the FIGS. 6 and 6A be explained.

As in particular from Fig. 2 . 2A and 3 can be seen, located at the top of the actuating bar 3, at the existing there upper wall or the web 9 an impression card receptacle 10, s. also Fig. 4 , in the present example, this web 9 and thus also the impression card holder 10, for example, are flat; However, it would also be conceivable, for example, a convex curved shape, as is known for example from the prior art. The impression card holder 10 has strip-shaped holding projections 11, which are provided, for example, on the two longitudinal sides, if necessary. Also on the shorter transverse sides of the impression card holder 10, and hold an inserted in this receptacle 10 impression card 12 and fix it in position see. the FIGS. 2 and 3 , In the case of longitudinal retaining projections 11, as shown, the impression card 12 can be mounted or removed particularly simply by longitudinal insertion or removal into the receptacle 10 or out of it, the window part 4 being approximately in the position shown in FIG Fig. 2 or Fig. 3 is pushed up.

Furthermore, located inside the window part 4, an information sheet 13, hereinafter also referred to briefly as an image card 13, cf. except Fig. 3 especially Fig. 5 , This image card 13 is, as in particular from Fig. 5 It can be seen, folded or bent in cross-section substantially similar U-shaped as the window part 4, and it has at its web top a recess 14 corresponding to the impression card 12, so when assembled stamp the impression card 12 through the transparent window part 4 therethrough and further through this recess or opening 14 can be seen therethrough. The image card 13 may carry on its two side walls outside additional information, such as the name and / or a picture of the Owner of the stamp 1 and the like more; In particular, this image card 13 may also have a certain signal color, which can be seen through the transparent window part 4, so as to form the upper part of the stamp 1, as seen in FIG Fig. 1 will be apparent to make correspondingly colored.

The remaining main components of the stamp 1, namely the stamp housing 2 and the actuating bow 3, can then be designed, for example, in a neutral color, in particular in white, so that the coloring of the image card 13 is achieved by the transparent vertical walls 15 (FIG. Fig. 1 ) of the window part 4 is noticeable.

In Fig. 4 the stamp 1 is shown without window part 4, wherein it is apparent that the in principle hood-shaped actuating bracket 3 is placed on the top of the punch housing 2, wherein the operating bracket 3 may be formed to save material with different recesses 16.

The bracket 3 carries on its two narrow sides (like legs) at the lower ends of plate-shaped, comparatively narrow bearing and locking projections 17, wherein in Fig. 4 only one of these projections 17 can be seen. Each of these bearing projections 17 on the one hand has a receiving bore 18 for the storage of journal 19 of a punch assembly 20, said punch assembly 20 in Fig. 4 is shown separated from the bearing projections 17 state. The narrow bearing and latching projections 17 can be bent elastically outward to let the journals snap 19 or - for an expansion of the punch assembly 20 - release. How far out Fig. 6 It can be seen in the interior of the stamp housing a known per se, generally designated 21 turning mechanism for the punch unit 20, also called stamp unit 20 is provided, with a detailed description of this turning mechanism 21 and its interaction with the punch unit 20 may be unnecessary, as this State of the art is well known. In Fig. 6 is schematically indicated at 19 'the axis of the punch assembly 20, which is defined by the two-sided axle journal 19, namely in particular when these axle pins 19 are received in the bearing bores 18.

The bearing projection 17 further has a transverse elongated locking recess 22, which serves to fix the separate frame part 8 via an existing thereon latching projection 23 by latching. This locking connection is in particular in Fig. 7 and Fig. 7A, respectively. It can be seen that the frame part 8 engages with a strip-like latching projection 23, for example, in the locking recess 22 when the frame part 8 with the operating bracket 3, specifically with its bearing projections 17, is connected.

Furthermore, it is off FIGS. 7 and 7A as well as out Fig. 4 recognizable that the actuating bracket 3 above the bearing projections 17 on the two narrow sides each have a locking element 24 is provided, which is movable relative to the rest of the actuating bracket 3 resiliently inwardly, approximately via a resilient connection with the rest of the actuating bracket 3; this locking element 24 forms with inside projections 25 ( Fig. 7 ) A catch or lock, which cooperates with corresponding recesses 26, 27 on the narrow sides of the punch housing, so as to be able to selectively fix the operating handle 3 on the die housing 2 in various predetermined positions.

As in particular from Fig. 6A it can be seen, the window part 4 has at its broad side walls 15 at the lower end a bend 28 with a shoulder 28 'and a latching hook 29, the latter engages in a latching recess 30 of the frame part 8 when the window part 4 is connected to the frame part 8 , The shoulder 28 'forms a stop element 28', with which the window part 4 comes to rest when pushed up relative to the operating bar 3 at a stop formed by a depression on the corresponding wall of the actuating clip 3 stop 31 so as to push the operating lever 3 relative to the rest Stamp 1 to limit, see Fig. 2 and 2A , Instead of such rectangular shoulder stop elements 28 ', 31, it would also be conceivable to provide corresponding locking elements, comparable to the locking elements 29, 30 between the window part 4 and frame part 8, so that the window part 4 when pushing up relative to the operating bracket 3 not only strikes, but also in this pushed-up intermediate position according to Fig. 2 and 2A fixed can be.

In Fig. 6 is then to complete a still acting between the actuating bow 3 and the die body 2 in a conventional manner itself compression coil spring 35 shown, the operating bracket 3 always in the upper rest position, according to Fig. 6 , presses. Also is in Fig. 6 For the sake of completeness, the color or ink pad 5 'contained in the ink pad container 5 is illustrated in more detail.

Out FIGS. 2 and 3 are further on the window part 4 on the narrow-side edges strip-shaped boundaries 32 visible, which protrude inward and so hold the image card 13 inside the window part 4. In addition, these strip projections 32 can also be used to guide the window part 4 at the corresponding edges 33 of the actuating bracket 3, 33 corresponding grooves or shoulders 34 are provided at these edges.

Of course, the image card 12 could also be held or preassembled on the outside of the actuating clip 3 instead of on the inside of the window part 4, with comparable strip-shaped boundaries or holders, possibly with undercuts, being provided there for this case.

Although the invention has been described in more detail with reference to the above particularly preferred embodiments, it will be understood that other modifications and variations are possible within the scope of the invention. So it is conceivable, for example, the stamp 1 instead of in cross section substantially rectangular in cross section square or oval or even circular, with flattened "narrow sides" to make, the flattened narrow sides allow the formation of practically flat legs of the actuating bracket 3 , It is also conceivable to omit the frame part 8 and to provide a uniform operating clip 3 in a conventional manner; in this case, the detent connection would be as in Fig. 6 and in particular FIG. 6A, instead of providing between the window part 4 and the frame part 8 between the window part 4 and the operating bar 3, with corresponding modifications within the scope of the technical knowledge are located. However, the frame part 8 offers the advantage that the bearing and latching projections 17 can either be concealed or exposed, the latter approximately in the case of installation or removal of the stamp assembly 20.

The window part 4, like the usual components 2, 3, 8 of the stamp 1 may be made of plastic, such as ABS or POM or PP, preferably the entire window part 4 is a transparent part, so as to have an unrestricted view of the impression card 12th and to enable the image card 13.

In Fig. 6 Further centering projections 36, 36 'are illustrated for the spring 35, as well as guide rails 37 for guiding the actuating bracket 3 on the narrow sides of the punch housing second
