Description

The invention relates to a stamp, as described in the preamble of claim 1.

From the WO 2006/079129 A1 and the EP 0 804 344 B1 is a stamp with overdye, also known as self-inking stamp known, which has a metal receiving frame for an impression unit, which is guided in side parts of the receiving frame. About the receiving frame formed a plastic base is placed. The impression unit is adjustable via a turning mechanism from a rest position, in which color is received by a cushion arranged in an ink pad, into an impression position counter to a spring force by a bow-shaped upper part. The bow-shaped upper part has in turn on the inside on a reinforcing bracket made of metal. Furthermore, in the middle of the bow-shaped upper part and in the center of the lower part on both sides of the strap spring elements for the provision of the upper part in the rest position. For fixing the upper part to the lower part locking elements are arranged in the lower part, which engage in a recess on the outside of the bow-shaped upper part. In this case, a height adjustment element are assigned to the impression unit for each adjusting element, in particular screws.

Such a construction of a tripod stamp by the applicant has, in contrast to the other prior art, such as US 2009/0255427 A , the AT 501 318 B and the DE 202010007577 U no central spar between the upper part and lower part. The central spar takes on the further state of the art, the spring element, so that now no spring elements are arranged on the side parts of the bow-shaped upper part. In this prior art can not be spoken of a bow-shaped upper part, since the central spar to the two side bars forms a central web. The main disadvantage of the tripod stamp with central spar is that there is no space for the arrangement of a viewing window and thus the pattern of the stamp imprint is arranged offset and extends to the side surface of the lower part.

The printing unit used in the aforementioned documents with attached MB unit (assembled tape unit) is designed such that the MB unit is adjusted over at least two adjusting elements, in particular screws, in height to the text plate. The disadvantage here is that an independent adjustment of the adjustment must be performed so that it is often the case that the MB unit is not aligned parallel to the text plate. This can lead to different imprints.

The object of the invention is to provide a stamp, an impression unit, an impression plate for an impression unit, in which an improved adjustment of the height for the punch bands is achieved. At the same time a simple adaptability and installation of the text plate should be created. Another task is to allow as late as possible individualization of the stamp.

The object of the invention is achieved by a stamp in such a way that the adjusting elements in a rest position or a stamp position on the front or back is accessible or actuated, wherein the adjusting element for height adjustment of the MB unit is formed.
It is advantageous in this case that the two punch position are available for a punch and thus no additional position for adjusting more are needed. At the same time the stamp can be easily placed and made on the front or back an adjustment. For this purpose, the stamp is preferably pressed together and it can then be easily made on the front or back, depending on where the adjustment is mounted, a setting.

But it is also an embodiment of advantage in which the adjusting element is arranged parallel to the text plate mounting surface. It is thereby achieved that in the corresponding positions, in particular in the rest position or in the position of the stem, the adjusting element can be achieved, wherein the punch can be set up.

Finally, a design of advantage, in which the height adjustment is preferably carried out via an angular slide track. This allows a simple construction, so that the impression unit is made as compact as possible.

The invention will now be described in the form of embodiments, it being understood that the invention is not limited to the illustrated and described embodiments or solutions.

In the Fig. 1 to 6 a stamp 1, in particular a tripod stamp 1 is shown, which comprises at least one stamp component 2 and an impression unit 3.

The stamp component 2 consists of at least one upper part 4 with a handle element 5 and a lower part 6 with a pad receiving element 7. The upper part 4 is preferably bow-shaped and has a longitudinal web 8 and two side elements 9,10, wherein the side elements 9,10 in the lower part 6 are guided. The impression unit 3 is connected via a turning mechanism 11, in the lower part 6 in motion-connected manner via an axis 12 or journal 12 to the upper part 4, so that the impression unit 3 in the lower part 6 of a rest position 13, according to Fig. 1 , in a printing or stamping position 14, according to Fig. 2 , by actuation of the upper part 4, in particular by pressurization of the handle element 5, can move. Of course, another structure is possible in which the upper part 4 is cap-like and receives the lower part 6 in the interior during a stamping process, as is the case with plastic self-inking stamp, for example in "Printy 4.0" from Trodat. In the rest position 12 is mounted on the impression unit 3 text plate 15 on a soaked with stamp ink stamp pad 16 in the pad receiving element 7, wherein in a stamping process for generating a stamp impression the impression unit 3 with the text plate 15 via the turning mechanism 11 from the rest position 13 via a rotational movement in the die position 14 is adjustable or is adjusted, that is, that the impression unit 3 is rotated about the axis 12, including the turning mechanism 11 is provided, in which a predetermined cam track 17, a rotation of the impression unit 3 is completed. Such turning mechanisms 11 or rotational movements are already known in such self-inking stamp 1, so it will not be discussed in detail. Only it should be noted that in the stamp 1 according to the invention a rigid slide track 17 is shown, but also a movable slide track (not shown) can be used. Of course, an equivalent structure of the components with a so-called central spar, as is known from the prior art possible, ie, that the same or aliquote parts are used, however, an additional central spar is used, in which a spring back provision in arranged the rest position 13, wherein in the illustrated stamp 1 in the side web 8.9 and lower part 6 is arranged.

In the illustrated stamp 1, a combination of metal parts 18 and plastic parts 19 is used, wherein the metal parts 18 are arranged externally visible. The metal parts are pushed over the plastic parts and engage via a latching connection (not shown), so that upon pressurization, the metal parts 18 take part of the pressure, ie, that the metal parts 18 support the plastic parts 19 in their stiffness, so no bending of Sharing is possible and thus an optimal impression with very high impression quality is achieved. The advantage of using a metal / plastic combination is that the plastic parts can be dimensioned smaller in their wall thickness, since the metal parts 18 also receives a portion of the forces acting.

The structure of the illustrated stamp 1 takes place in the stamp component 2 in the form of a kit, ie, that the same parts of the stamp components 2 are used for a variety of versions of the stamp 1 such as tripod stamp 1 with a text plate as well as tripod stamp 1 with a MB unit (mounted-band set unit) 19, wherein the individualization takes place only by the onset of the impression unit 3.

For this purpose, the MB unit 19 can be inserted into the impression unit 3, wherein these are preferably guided on two sides via guide elements 20 on the impression unit 3, in particular a text plate carrier 21. For this purpose, the MB unit 19 has a base body 22 and a closure element 23. The main body 22 has a preferably round receiving element 24 and a so-called bridge 25. On the receiving element 24 a plurality of belt drives 26, which are formed from an adjusting wheel 27 and a motion-coupled driver 28, respectively. At the driver 27 of the tape drive 26 each a stamping belt 29 is arranged, wherein in the illustrated embodiment, the MB unit 19 is designed as a date, and thus four punch bands 29 (two daytime tapes, a monthly tape and a year tape) and four tape drives 26 on the receiving element 24th to be assembled. The punch bands 29 are guided over the bridge 25, which is preferably adjustable, so that a corresponding band tension can be set up and adjusted. Thus, the belt drives 26 can not slip from the base body 22, then the final element 23 is attached, which can be done for example with a locking connection. Preferably, the end member 23 is only plugged, as by the assembly on the impression unit 3, the closing element 23 can not slip from the base body 22 through the two guide elements 20, 21.

Preferably, at least the driver 27 of the belt drive 26 is formed from a two-component injection molded part, wherein a surface 30 of the driver 27 is formed of a material having high frictional properties for safe further transport of the punch belt 29. The punch band 29 itself has on the side facing the driver 27 a smooth or slightly roughened surface, so that a frictional engagement for the transport of the punch belt 29 is provided via the driver 27. As a result, a transport system for the punch belt 29 for the stamp 1, in particular a tripod stamp created that at least the belt drive 26, which consists of an adjusting element 27 with a motion-coupled driver 28 for the punch belt 29, and the so-called bridge 25 for deflecting and Positioning of the punch band 29 in the impression area comprises, wherein the driver 28 and the bridge 25 are positioned relative to each other such that the punch band 29 is held and stretched by them. Of course, it is also possible that the surface 30 may have a structure which engages in a corresponding structure on the punch band 29, wherein due to the two-component injection molded parts, a high frictional engagement is formed, since the materials of the surface 30 is matched with the punch band material to to ensure a safe transport.

In the illustrated embodiment, a tape cover 31 is provided, which is simply plugged, as in the prior art, in particular from AT 503570 B or the AT 504428 B , is known, so that it is not discussed further.

In the case of the inventive impression unit 2, a central height adjustment 32 for the MB unit 19 is now provided in order to allow a simple and rapid adaptation of the MB unit 19. As a central element is a height adjustment element 33, according to Fig. 6 , which simultaneously serves for guiding and height adjustment 32 of the MB unit 19. The height adjustment element 33 is connected to an adjusting element 34, in particular with a preferably centrally arranged adjusting screw 35, or is in operative connection therewith, so that the height adjustment element 33 is displaced by actuation of the adjusting element 34. Preferably, the height adjustment element 33 an angularly extending slide track 36 and a horizontally extending guide track 37, wherein in the illustrated embodiment in each case two slide tracks 36 and guideways 37, which are laterally arranged or integrally formed on a central web 38. The guideways 37 engage in guides 39 on the lateral guide elements 20, 21 of the impression unit 3 and the slide track 36 in corresponding guides 40 on the base body 22 and end member 23 of the MB unit 19 a. This ensures that the MB unit 19 is movably mounted on the angular slide track 36 for the height adjustment 32 and this is simultaneously guided over the guide track 37 in the horizontal direction of the impression unit 3.

To adjust the height adjustment element 33, it is necessary that the adjusting element 34 is actuated, whereby the height adjustment element 33 is displaced in the horizontal direction, i. that the central web 38 is in operative connection with the adjusting screw 35, so that by turning the adjusting screw 35, this is screwed or rotated and thus the central web 38 is also moved horizontally with the slide tracks 36 and guideways 37. Since the MB unit 19 is guided vertically in the guide elements 20, 21, this can not be moved horizontally, but slides along the angular slide track 36 in the vertical direction still up or down, depending on the rotational movement of the adjusting 35th

It is essential in the height adjustment 32 according to the invention that this is now with only a single adjustment 34, in particular a single adjustment screw 35, to use, whereby a parallel displacement of the entire MB unit 19 to the text plate 15 via the angular slide track 36 takes place or is achieved , This makes it possible for the first time that with a punch 1 with a turning mechanism 11 with only one adjusting screw 35, an adjustment of the height for the MB unit 19 can be made. In this case, the central height adjustment 32 is arranged directly on the impression unit 3, so that it also performs a rotation in a stamping operation. A significant advantage lies in the fact that the access to the adjusting element 34, in particular the adjusting screw 35, takes place laterally, so that in the rest position 13 and in the position of the piston 14, the adjusting element 34 can be easily achieved, whereas in the prior art this is not the case , Since the usual two screws from above, so in the range of Verstellräder 27 are arranged so that only in the Rest position 13 from below or in a half position of the piston from the side of the punch 1 access is possible.

Of course, it is possible that the adjusting element 34 is not arranged in the center of the central web 38, but the adjusting elements 34 may be positioned in the side areas.

Furthermore, it is also possible that the embodiment described above can be constructed in reverse, that is, that not MB unit 19 is adjusted in height, but that the text plate 15 or text plate carrier 21 is adjusted in height on the adjusting element 34. It is essential in the solution according to the invention that the support plate 15 or the text plate carrier 21, in particular a text plate mounting surface 41 and MB unit 19 are mutually adjustable in height, so that a corresponding adjustment can be performed. This is necessary insofar as different MB units 19 are used with different thickness stamping bands 29 or various text plates 15 made of different thicknesses of materials, especially rubber, so that a corresponding adjustment is necessary.

As described, in the first embodiment, the adjustment thereby takes place via only one adjusting element 34, in particular a centrally disposed adjusting screw 35, whose accessibility over the longer free side of the punch 1, ie a front 42 or back 43, in the rest position 13 and in the stamp position 14 takes place. This accessibility is essential insofar as it is possible for the first time, the punch 1 in the punch position 14, according to Fig. 2 to bring and make in this the adjustment, ie, that, for example, the punch 1 is brought into the punch position 14 and preferably locked, whereupon the front or back 42,43 the MB unit 19 is set, for which purpose the stamp can be placed on a surface, and then the MB unit 19 is added. Thus, the stamp maker or user gets set up stamp 1 on a table or a surface when adjusting a feedback, since the MB unit 19 is also pressed against the table or the surface, so that a corresponding stop is present and thus the stamp maker or User knows that now both components, so the text plate 15 and the MB unit 19 are on a same level or level.

In the Fig. 7 and 8th Now, a further embodiment is shown, in which the height adjustment via a plurality, in particular two adjusting elements 34, 44, whereby these are preferably independently adjustable. This corresponds to a similar structure, as it is known from the prior art, wherein in the prior art, the adjustment via the adjusting screws always from above, so on the top in the direction of the punch bands 29 of the MB unit 19 takes place, whereas in the new setting system according to the invention the setting laterally, that is 90 offset from the alignment of the punch bands 29, takes place.

In this case, an adjusting element 34, 44 is arranged on each side of the MB unit 19, these now being designed as adjusting levers 45, 46, so that no additional tools, such as a screwdriver, are required for the adjustment. Of course, it is also possible, instead of the adjusting lever 45,46, the adjusting screws 35 can be used. Preferably, the two adjustment 34,44 are not in operative connection, but can independently perform a height adjustment of the MB unit 19 or text plate mounting surface 41 on each side of the MB unit 19, that is, the adjustment of the height of the MB unit 19 via the two adjusting elements 34,44, in which case stepwise on each side of the MB unit 19, these are raised or lowered to the text plate mounting surface 41 or vice versa. With such a design with independent adjustment elements 34, 44, it is possible for the MB unit 19 to be aligned obliquely, in particular at an angle, to the text plate mounting surface 41. This is advantageous if an MB unit has 19 different punch bands 29, or the manufacturing tolerances in the punch bands 29 is very high, since then a corresponding oblique orientation can take place.

It is essential over the prior art, that now for the first time the adjustment 34, 44 on the front and back 42,43 of the stamp 1 in the rest position 13 or in the stamp position 14, so that a very easy accessibility in the existing positions, is given and not an additional adjustment position is required in which the punch 1 is pressed only halfway together, so that the accessibility to the top of the MB unit 19 on the front 42 and back 43 is possible, for which purpose preferably a separate locking position is arranged As realized in the prior art, since in the prior art, the adjustment are arranged and accessible at the top.

In the illustrated embodiment of the Fig. 7 For example, the lifting and lowering of the MB unit 19 may be via a spindle, eccentric, or other lifting mechanism that deflects the horizontal rotary motion into a vertical lifting motion, wherein it is essential that accessibility be in the rest position 13 and / or in the punch position 14 over the front 42 or back 43 or from both sides.

In Fig. 8 an embodiment is shown in which the adjusting elements 34,44 again takes place via an angular cam tracks 36. In this case, the adjusting elements 34, 44 are now arranged above or in the region of an upper side 47 of the MB unit 19 in the guide elements 20, which in turn however parallel to the text plate mounting surface 41, ie rotated by 90 ° to the punch direction of the MB unit 19, are arranged. The angular slide track 36 is now arranged in a channel 48, in which the adjusting element 34, 44 engages. The adjusting element 34, 44 is designed as an adjusting screw 35, 49, wherein the adjusting screws 35, 49 have a corresponding angled surface 50. This makes it possible that by turning the adjusting screw 35,49 or turn out the adjustment screws 35,49 the MB unit 19 is adjusted in height, the MB unit 19 for this purpose with a height adjustment 51, which in the guide elements 20th is guided, connected and in which the channel 48 is arranged. So that a height adjustment of the MB unit 19 is possible, the height adjustment element 51 has a slot 52 for the axis 12.

Of course, it is possible that the channel 48 is arranged with the angular slide track 36 directly to the MB unit 19, so that the MB unit 19 is inserted into the guide elements 20. Subsequently, the adjusting screws 35,49 are screwed via a provided with a thread 53 bore 54 in the guide member 20, so that the adjusting screws 35, 49 engage in the channel 48.

Preferably, the MB unit 19 is supported by a spring member (not shown), so that the MB unit 19 is always urged in a certain direction. This ensures that when adjusting the adjusting elements 34, 44, the MB unit 19 is pressed against the angular slide track 36, so that an optimal displacement along the slide track 36 is possible. Both training with tension spring or compression spring is possible.

In Fig. 9 is a kind of exploded view of the most important elements for an embodiment of an adjustment of the text plate carrier 21 shown with a central height adjustment 32, ie that now the MB unit 19 is fixed and upon actuation of the adjusting element 34 of the text plate carrier 21 to the MB unit 19 in height is adjusted.

As can now be seen from the individual elements, the base body 22 and the closing element 23 in the region of the bridge 25 has a bore 55 for the axis 12. Thus, the MB unit is fixed in the assembled state, as through the bore 55 no more displacement is possible. In the embodiment described above, the MB unit 19, in particular the base body 22 and the closing element 23 was equipped with a slot for the height adjustment. A corresponding elongated hole 56 is now arranged on the text plate carrier 21, so that the entire text plate carrier 21 can be adjusted via the adjusting element 34 to the MB unit 19 in height.

In Fig. 10 an embodiment is shown in which the MB unit 19 is resiliently mounted on the text plate carrier 21 of the impression unit 3. For this purpose, a spring element 57 is arranged such that it presses the MB unit 19 in a certain direction, so that there is always a defined position of the MB unit 19.

In the embodiment shown, a compression spring is used as a spring element 57, which presses the MB unit 19 in the direction of the text plate mounting surface 41. As a result, the MB unit 19 can now be placed beyond the text plate 15 (not shown) in the case of the height adjustment 32, since during a stamping operation the MB unit 19 builds up an additional pressure via the spring element 57. Thus, the height adjustment 32 does not have to be carried out exactly, since an independent adaptation is carried out via the spring element 57.

Of course, it is possible that the previously described embodiments can be equipped with a corresponding spring element 57. It is also possible that with appropriate design, a tension spring can be used.

For the sake of order, it should finally be pointed out that for a better understanding of the construction of the system 1 and its components or their components, they have been shown partially unevenly and / or enlarged and / or reduced in size.
