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 a stamp with overlap coloring, also known as self-inking stamp, is known which has a metal receiving frame for an impression unit, which is guided in side parts of the receiving frame. A lower part made of plastic is placed over the receiving frame. The impression unit can be adjusted via a turning mechanism from a rest position, in which ink is received by a cushion arranged in a stamp pad, to an impression position against a spring force by means of a bow-shaped upper part. The bow-shaped upper part in turn has a reinforcement bracket made of metal on the inside. Furthermore, spring elements for the return of the upper part to the rest position are in the middle of the bow-shaped upper part and in the center of the lower part on both sides of the bracket. To fix 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. A height adjustment element is assigned to each adjustment element, in particular screws, on the impression unit.

Such a structure of a tripod stamp by the applicant, in contrast to the further prior art, such as the US 2009/0255427 A , of the AT 501 318 B and the DE 202010007577 U no central spar between the upper part and lower part. In the further prior art, the central stringer receives the spring element, so that spring elements are no longer arranged on the side parts of the bow-shaped upper part. In this prior art, it is also not possible to speak of a bow-shaped upper part, since the central stringer forms a central web on the two side webs. 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 impression is offset and extends to the side surface of the lower part.

The impression unit used in the aforementioned documents with the MB unit attached to it (assembled belt unit) is designed such that the height of the MB unit is adjusted to the text plate by means of at least two adjusting elements, in particular screws. The disadvantage here is that the adjustment elements must be adjusted independently of one another, so that it is very often the case that the MB unit is not aligned parallel to the text plate. This can lead to different impression images.

The object of the invention is to provide a stamp in which an improved possibility of adjusting the height for the stamp tapes is achieved. At the same time, the text plate should be easy to adapt and assemble. Another task is to enable the stamp to be customized as late as possible. The object of the invention is achieved by a stamp in such a way that the adjusting element is accessible or actuatable from the front or rear in a rest position or a stamp position, the adjusting element being designed for height adjustment of the MB unit.

It is advantageous here that the two stamp positions are available for one stamp and therefore no additional position for setting is required. At the same time, the stamp can be easily set up and adjusted via the front or back. For this purpose, the stamp is preferably pressed together and an adjustment can then simply be made via the front or back, depending on where the adjustment element is attached. However, an embodiment is also advantageous in which the adjusting element is arranged parallel to the text plate mounting surface. It is thereby achieved that the adjustment element can be reached in the corresponding positions, in particular in the rest position or in the stamp position, it being possible for the stamp to be set up. Finally, an embodiment is advantageous in which the height adjustment is preferably carried out via an angular slide track. This enables a simple structure, so that the impression unit is as compact as possible.

The invention is subsequently described in the form of exemplary embodiments, it being pointed out that the invention is not limited to the exemplary embodiments and solutions illustrated and described.

In the introduction, it should be noted that in the different embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The position information selected in the description, such as, for example, top, bottom, side, etc., are related to the figure described and are to be transferred to the new position in the event of a change in position.

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

The stamp component 2 consists at least of an upper part 4 with a grip element 5 and a lower part 6 with a cushion receiving element 7. The upper part 4 is preferably bow-shaped and has a longitudinal web 8 and two side elements 9, 10, the side elements 9, 10 in the lower part 6 are performed. The impression unit 3 is connected to the upper part 4 via a turning mechanism 11, in the lower part 6 in a motion-connected manner via an axis 12 or axle journal 12, so that the impression unit 3 in the lower part 6 moves from a rest position 13 according to Fig. 1 , in a printing or stamp position 14, according to Fig. 2 , can move by actuating the upper part 4, in particular by pressurizing the grip element 5. Of course, another construction is also possible in which the upper part 4 is cap-shaped and receives the lower part 6 in the interior during a stamping operation, as is the case with plastic self-inking stamps, for example in the "Printy 4.0" from Trodat. In the rest position 12, a text plate 15 mounted on the impression unit 3 bears against a stamp pad 16 impregnated with stamp ink in the cushion receiving element 7, with the impression unit 3 with the text plate 15 via the turning mechanism 11 from the rest position 13 during a stamping process for producing a stamp impression a rotary movement in the stamp position 14 is adjustable or is adjusted, ie the impression unit 3 is rotated about the axis 12, for which purpose the turning mechanism 11 is provided, in which the impression unit 3 is rotated via a predetermined slide track 17. Such turning mechanisms 11 or rotary movements are already known in self-inking stamps 1 of this type, so that they will not be discussed in more detail. It is merely pointed out that a rigid slide track 17 is shown in the stamp 1 according to the invention, but a movable slide track (not shown) can also be used. Of course, an equivalent construction of the components with a so-called central spar, as is known from the prior art, would also be possible, ie that the same or aliquot parts are used, but an additional central spar is used, in which a spring is reset to the rest position 13 is arranged, with the stamp 1 shown being arranged in the side web 8, 9 and lower part 6.

In the illustrated stamp 1, a combination of metal parts 18 and plastic parts 19 is used, the metal parts 18 being arranged so as to be visible on the outside. The metal parts are pushed over the plastic parts and snap into place via a snap connection (not shown), so that when pressurized, the metal parts 18 absorb part of the pressure, that is to say that the metal parts 18 support the plastic parts 19 in their rigidity, so that 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 terms of their wall thickness, since the metal parts 18 also absorb part of the acting forces.

The stamp 1 shown is constructed for the stamp component 2 in the form of a modular system, that is to say that the same parts of the stamp components 2 are used for the most varied designs of the stamp 1, for example tripod stamp 1 with a text plate and tripod stamp 1 with a MB unit (assembled belt set unit) 19, the individualization only taking place by inserting the impression unit 3.

For this purpose, the MB unit 19 can be inserted into the impression unit 3, which 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 an end element 23. The base body 22 has a preferably round receiving element 24 and a so-called bridge 25. A plurality of belt drives 26, which are formed from an adjusting wheel 27 and a movement-coupled driver 28, are arranged on the receiving element 24. A stamping tape 29 is arranged on the driver 27 of the tape drive 26, the MB unit 19 being designed as a date in the exemplary embodiment shown, and thus four stamping tapes 29 (two daily tapes, a monthly tape and an annual tape) and four tape drives 26 on the receiving element 24 to be assembled. The stamping strips 29 are guided over the bridge 25, which is preferably adjustable, so that a corresponding strip tension can be built up and adjusted. So that the belt drives 26 cannot slide off the base body 22, the terminating element 23 is then plugged on, which can be done, for example, with a snap connection. The terminating element 23 is preferably only plugged on because of the assembly on the impression unit 3, the closure element 23 cannot slide off the base body 22 through the two guide elements 20, 21.

At least the driver 27 of the belt drive 26 is preferably formed from a two-component injection molded part, a surface 30 of the driver 27 being formed from a material with high frictional connection properties for the safe further transport of the stamping tape 29. The stamping tape 29 itself has a smooth or slightly roughened surface on the side facing the driver 27, so that a frictional connection is created for the transport of the stamping tape 29 via the driver 27. This creates a transport system for the stamp tape 29 for the stamp 1, in particular a tripod stamp, which has at least the tape drive 26, which consists of an adjusting element 27 with a movement-coupled driver 28 for the stamp tape 29, and the so-called bridge 25 for deflecting and Positioning of the stamping tape 29 includes in the impression area, the driver 28 and the bridge 25 being positioned relative to one another such that the stamping tape 29 is held and tensioned by them. Of course, it is also possible that the surface 30 can have a structure which engages in a corresponding structure on the stamping tape 29, a high frictional engagement being formed on account of the two-component injection molded parts, since the materials of the surface 30 are coordinated with the stamping tape material to ensure safe transport.

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

In the inventive impression unit 2, a central height adjustment 32 is now provided for the MB unit 19 in order to enable the MB unit 19 to be easily and quickly adapted. A height adjustment element 33 according to FIG Fig. 6 , arranged, which serves both for guidance and for height adjustment 32 of the MB unit 19. The height adjustment element 33 is connected to an adjustment element 34, in particular with a preferably centrally arranged adjustment screw 35, or is operatively connected to it, so that the height adjustment element 33 is displaced by actuating the adjustment element 34. The height adjustment element preferably has 33 has an angularly extending guide track 36 and a horizontally running guide track 37, with two guide tracks 36 and guide tracks 37, which are arranged or formed laterally on a central web 38, in the illustrated embodiment. The guide tracks 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 element 23 of the MB unit 19. It is thereby achieved that the MB unit 19 is movably mounted for the height adjustment 32 via the angled link track 36 and at the same time it is guided in a horizontal direction on the impression unit 3 via the guide track 37.

To adjust the height adjustment element 33, it is necessary that the adjustment element 34 be actuated, whereby the height adjustment element 33 is displaced in the horizontal direction, i.e. that the central web 38 is operatively connected to the adjusting screw 35, so that the adjusting screw 35 is screwed or unscrewed by turning the adjusting screw 35 and thus the central web 38 with the link tracks 36 and guide tracks 37 is also moved horizontally. Since the MB unit 19 is guided vertically in the guide elements 20, 21, it cannot be moved horizontally, but instead slides along the angular slide track 36 in the vertical direction up or down, depending on the rotary movement of the adjusting screw 35.

It is essential in the case of the height adjustment 32 according to the invention that it can now be operated with only a single adjustment element 34, in particular a single adjustment screw 35, as a result of which the entire MB unit 19 is moved or achieved parallel to the text plate 15 via the angular slide track 36 . This makes it possible for the first time that the height of the MB unit 19 can be adjusted in the case of a stamp 1 with a turning mechanism 11 with only one adjusting screw 35. The central height adjustment 32 is arranged directly on the impression unit 3 so that it also rotates during a stamping operation. A significant advantage is also that the adjustment element 34, in particular the adjustment screw 35, is accessed laterally, so that the adjustment element 34 can be easily reached in the rest position 13 and in the stamp position 14, whereas this is not the case in the prior art , since the usual two adjusting screws are arranged from above, ie in the area of the adjusting wheels 27, so that only in the Rest position 13 from below or in half a stamp position from the side of the stamp 1 access is possible.

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

Furthermore, it is also possible that the embodiment described above can be constructed in reverse, i.e. that the height of the MB unit 19 is not adjusted, but that the height of the text plate 15 or text plate carrier 21 is adjusted via the adjusting element 34. It is essential in the solution according to the invention that the carrier plate 15 or the text plate carrier 21, in particular a text plate mounting surface 41 and MB unit 19, can be adjusted in height with respect to one another, so that a corresponding adjustment can be carried out. This is necessary because different MB units 19 with stamp strips 29 of different thicknesses or different text plates 15 made of materials of different thicknesses, in particular rubber, are used, so that a corresponding adjustment is necessary.

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

In the Fig. 7 and 8th A further exemplary embodiment is now shown, in which the height adjustment takes place via several, in particular two, adjustment elements 34, 44, these preferably being adjustable independently of one another. This corresponds to a structure similar to that known from the prior art, the adjustment in the prior art always using the adjusting screws from above, i.e. on the top in the direction of the stamping tapes 29 of the MB unit 19, whereas the new adjustment system according to the invention, the adjustment laterally, that is offset by 90 to align the stamping tapes 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 to use the adjusting screws 35 instead of the adjusting levers 45, 46. The two adjustment elements 34, 44 are preferably 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, ie that the height of the MB unit is adjusted 19 takes place via the two adjusting elements 34, 44, with the MB unit 19 being raised or lowered to the text plate mounting surface 41 step by step on each side or vice versa. With such a configuration with independent adjustment elements 34, 44, it is possible that the MB unit 19 can now be aligned obliquely, in particular at an angle, to the text plate mounting surface 41. This is advantageous if an MB unit 19 has different stamping tapes 29 or the manufacturing tolerances for the stamping tapes 29 are very high, since a corresponding oblique alignment can then take place.

It is essential compared to the prior art that for the first time the adjustment elements 34, 44 take place via the front or rear side 42, 43 of the stamp 1 in the rest position 13 or in the stamp position 14, so that very easy accessibility in the existing positions, is given and an additional setting position is not required, in which the stamp 1 is only pressed half together, so that access to the top of the MB unit 19 is possible via the front 42 or rear 43, for which purpose a separate blocking position is preferably arranged for this purpose how this is achieved by the prior art, since in the prior art the adjusting element is arranged on the top and is accessible.

In the illustrated embodiment of the Fig. 7 the MB unit 19 can be raised and lowered by means of a spindle, eccentric, or other lifting mechanisms which deflect the horizontal rotary movement into a vertical lifting movement, it being essential that the accessibility in the rest position 13 and / or in the stamp position 14 on the front 42 or back 43 or from both sides.

In Fig. 8 An exemplary embodiment is shown in which the adjusting elements 34, 44 in turn take place via an angled link tracks 36. The adjusting elements 34, 44 are now arranged above or in the area of an upper side 47 of the MB unit 19 in the guide elements 20, which, however, are in turn parallel to the text plate mounting surface 41, that is to say rotated by 90 ° to the stamp 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, the adjusting screws 35, 49 having a corresponding angular surface 50. This makes it possible for the MB unit 19 to be adjusted in height by turning the adjusting screw 35, 49 or unscrewing the adjusting screw 35, 49, for this purpose the MB unit 19 having a height adjusting element 51, which is located in the guide elements 20 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 an elongated hole 52 for the axis 12.

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

The MB unit 19 is preferably mounted via a spring element (not shown), so that the MB unit 19 is always pressed in a certain direction. It is thereby achieved that when adjusting via 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. Training with a tension spring or compression spring is possible.

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

As can now be seen from the individual elements, the base body 22 and the end element 23 have a bore 55 for the axis 12 in the region of the bridge 25. The MB unit is thus fixed in the assembled state since it is no longer possible to move through the bore 55. In the exemplary embodiment described above, the MB unit 19, in particular the base body 22 and the end element 23, was equipped with an elongated hole 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 in height to the MB unit 19 via the adjusting element 34.

In Fig. 10 An embodiment is shown in which the MB unit 19 is resiliently mounted on the text plate carrier 21 of the printing 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 the 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 above the text plate 15 (not shown) at the height setting 32, since the MB unit 19 builds up additional pressure via the spring element 57 during a stamping operation. Thus, the height adjustment 32 does not have to be carried out exactly, since an independent adjustment is carried out via the spring element 57.

Of course, it is also possible that the embodiment variants described above can also be equipped with a corresponding spring element 57. It is also possible that a tension spring can be used with a corresponding construction.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the system 1 and its components or its components, some have been shown to scale and / or enlarged and / or reduced.
