Technical Field

The invention relates to a tilting device for an automatic inking stamp, comprising a housing, which has a control curve for a tilting shaft, which curves at least in sections, on two opposite side walls, and an actuating bracket, which is connected to the housing and is movable relative to the housing, which has a guide device for the tilting shaft, which is arranged transversely to the direction of movement of the actuating bracket relative to the housing, on two legs arranged parallel to the side walls of the housing, wherein the guide device and the control curve overlap at least on a first side and in at least one position of the actuating bracket relative to the housing and form an opening that can be penetrated from the outside, such that the tilting shaft can be inserted into the tilting device from the outside in the longitudinal direction. The tilting device has neither a stamp nor a stamp pad and a tilting axis and is therefore not a complete stamp per se. The guide device is used for movably supporting the overturning shaft.

Background

The advantage of such a turning device is that it allows personalization of the stamp as late as possible: universal flipping devices without stamps (board carriers or word modules) can be manufactured, delivered and stored in relatively large quantities; all possibilities for personalization are thus left open and personalization can be done close to and immediately before acceptance or by the end-customer himself who separately takes the impression and assembles it with the turning device. For example, a standardized turning device can be produced and stored independently of international differences (for example, different date formats for european or north american character models).

Such a flipping device is already known from AT 517322 a 1. The stamp and the turning shaft can be removed from the stamp shown there, thus forming a turning device. The tilting device is relatively complex in construction, since it is intended to avoid a central strut and therefore the spring elements are arranged laterally in the two legs of the operating bow. With this arrangement, in one embodiment, the housing is closed at the sides and the shaft cannot be removed in its longitudinal direction; for removal, the control curve (or slide) is interrupted by a replacement channel along which the tumble shaft is inserted or removed in a radial direction (i.e. transverse to the shaft). The device allows the use of an impression with an integrally formed stub shaft. The disadvantage here is the complicated construction and the need to lock the replacement channel in order to avoid an accidental drop out of the stamp.

AT 517322 a1 shows another flipping mechanism. In this case, a shaft replacement opening for the through-shaft is provided on the upper or lower arcuate portion in order to subsequently mount the text panel holder.

CA 1037313 a also shows a flipping arrangement where the shaft passes through a control curve in the frame to the outside of the leg. US 2012017786 a1 likewise shows a roll-over axis through the leg vertical guide and the housing control curve. AT 379552B shows a stamp insert having a pivot shaft that passes through both the control slot and the elongated hole. US 3099955 a also shows a roll-over axis of a printing unit passing through the control curve of the sides of the base frame.

Other flipping devices are described in CN 204998164U, CN 201506087U and US 3714894 a.

Disclosure of Invention

The object of the present invention is to provide a turning device which avoids the above-mentioned disadvantages.

According to the invention, this object is achieved in a turning device of the type mentioned at the outset in that: the guide devices each have a movably mounted sliding bushing with a bearing for the tilting shaft.

This eliminates the need to replace the channel and the corresponding locking device. The housing also has a receptacle for the pad holder. The handling bow is held in the stamp-coloring position by a spring element and can be moved into the stamping position against the spring force of the spring element. The control curve can be, for example, a control slot or can be formed by a groove closed on one side. The guide means in the leg can be configured, for example, as a slot. The movement direction of the actuating bracket corresponds to the stamping direction during operation, i.e. for forming the stamping, the actuating bracket is moved in the stamping direction relative to the housing. The guide means comprise, for example, a sliding bearing for the tumble shaft.

Accordingly, the above-mentioned object is achieved by a method for producing an automatic inking stamp using such a tilting device, a stamp and a tilting shaft, comprising the following steps: inserting the stamp into the flipping device from the underside; and the roll-over shaft is inserted in the longitudinal direction of the roll-over shaft from the first side through the housing and the handling bow, through the impression as far as the second side of the housing and the handling bow.

The guide or the control cam can have a stop on a second side opposite the first side for the tilting shaft inserted in the longitudinal direction. Such a stop can prevent the tilting shaft from sliding through in the longitudinal direction and thus assist in a defined and correct positioning of the tilting shaft in the finished stamp.

Optionally, at least one of the guides may have a connecting element for establishing a snap connection with the tumble shaft received therein. The connecting element can be, for example, a catch or a catch shoulder which can engage in an annular groove in the tumble shaft in order to prevent an unintentional movement in the longitudinal direction. This fixation may be designed such that it creates a resistance that can be overcome with sufficient force to allow for the deliberate removal of the flip axis and replacement of the impression.

Furthermore, the actuating bracket can have a first limiting element and the housing can have a corresponding second limiting element, both limiting elements being designed to limit the movement of the actuating bracket and to prevent the actuating bracket from separating from the housing. Such precautions ensure that the turning device does not break down into its individual parts when operating only on the housing or only on the operating bow, even without the shaft being incorporated.

The guide devices each have a movably mounted sliding bushing with a bearing for the tilting shaft. The support leg of the actuating bow can have a sliding bearing for the sliding bushing; for example, each sliding bush can be mounted movably in an elongated hole formed in the leg. The above-mentioned optional connecting element may be part of at least one of said sliding bushes; for example in the form of a resiliently radially deflectable latching element with a radially inwardly directed latching projection which can engage in a latching recess in the tumble shaft, for example a circumferential annular groove. The shaft support formed by the sliding bush may be a rotational sliding support.

In the case of the use of a sliding bush, it can be provided that the guide is a linear guide for a movably mounted sliding bush. That is to say, the sliding bush is prevented from moving in the direction of the longitudinal axis of the tumble shaft accommodated therein. For example, the edge strips of the linear guide can engage in parallel grooves in the sliding bush, so that the sliding bush is guided linearly along the edge strips. Thereby, the sliding bush is fixed in a direction parallel to the longitudinal direction of the tumble shaft, so that the sliding bush remains in its position when the tumble shaft is inserted or withdrawn.

Furthermore, at least one of the sliding bushes may form a first limiting element. The sliding bush here forms a projection on the inside or outside of the leg, which in the direction of the stamp coloring position strikes a stop on or in the housing, such as a slot edge in the housing, and prevents further movement of the actuating bracket in the direction away from the housing.

The individualization of the stamp can be simplified in particular if the present tilting device is used if the sliding sleeve is connected to a stamp frame for receiving the stamp. The impression can be, for example, a text sheet carrier with a text sheet or a character module.

Accordingly, the present disclosure provides an alternative variation of the above method, wherein the stamp is inserted into the stamp frame.

In the case of the stamp frame, it can be provided that at least one of the sliding sleeves is connected to the stamp frame by a snap connection. The impression frame is thus held in the housing by the sliding bushing and is held there even without the tumble shaft. In particular, the sliding bush can have, for example, a tenon which snaps into a receptacle in the impression frame.

Finally, the disclosure also relates to an automatic inking stamp having a flipping device according to one of the variants described above, a stamp accommodated therein, and a flipping axis extending through the flipping device and the stamp.

In this case, it can be provided that the tilting shaft is connected to the stamp by a snap connection and is fixed against movement in the longitudinal direction of the tilting shaft. For example, the snap-in protrusions in the stamp can be embedded in annular grooves in the middle part of the tumble shaft, which is the part of the tumble shaft along which the stamp extends.

Detailed Description

Fig. 1 to 5 show a first embodiment of a turning device 1.

Turning device 1 is shown in fig. 1 and 2 in isolation, i.e. as an incomplete self-inking stamp prior to personalization. The components 2 to 4 that can be used for individualization and for completing the stamp are shown separately in fig. 1: a stamp holder 2 with a stamp pad, a turning shaft 3 and a stamp 4 in the form of a character die set (or a text sheet carrier with a text sheet).

As can be seen in particular from fig. 2, the turning device 1 comprises a housing 5, an operating bow 6 and an impression frame 7. The housing 5 has a control curve 10 for the tilting shaft 3, which curve at least in sections, on two opposite side walls 8, 9. The two control curves 10 are configured as curved slots in the side walls 8, 9. The housing 5 is connected to a cover 11 and a mirror 12, the cover 11 covering an insertion compartment 13 for the stamp pad holder 2 and the mirror 12. The cover 11 and the mirror 2 are pivotally snapped onto the housing. The carrier plate 14 is pushed onto the actual (inner) housing 5 from below. The bracket plate 14 covers most of the control curve 10 towards the outside on both sides (see fig. 5). As a result, a receiving space for the actuating leg 15 of the bracket 6 is left on both sides between the housing 5 and the carrier plate 14 and thus prevents objects from colliding or becoming jammed. On the upper side 16 of the housing 5, the housing has a vertical support 17 and two passage slots 18 for the legs 15. Next to the control curve 10, on the inner side of the side walls 8, 9, there are provided tilting pins 41, which are each guided in a corresponding receptacle 19 in the stamp frame 7 and, together with the control curve 10, cause the stamp frame 7 to be tilted together with the stamp 4 accommodated therein when the handling bracket 6 is moved between the stamping position (see fig. 3) and the stamp inking position (see fig. 5). On the underside 39 of the housing 5, legs 40 are connected with the housing and are fixed by a snap connection. The foot 40 can serve as a closure for the (optionally) open control curve 10 and has a non-slip base made of rubber. The first leg 40 on the first side 29 has an opening 42 for inserting and removing the tumble shaft 3, while the second leg 40 does not have such an opening.

The actuating bracket 6 passes through the passage slot 18 of the housing 5 and is movable relative to the housing (see fig. 3 and 5). The outer edges of the legs 15 are guided linearly along and between two parallel guide surfaces 20 in the housing 5. The actuating bracket 6 has a guide 21 for the tilting axis on each of the two legs 15 arranged parallel to the side walls 8, 9 of the housing 5 (see fig. 4). The two guide devices 21 each have an elongated hole 22 with a constant width in the working region 23 and a widened section 24 next to the working region 23 for inserting a sliding bush 25 during the production of the folding device 1. The working region 23 is the region in which the sliding bush 25 moves when the stamp is operated, based on the extension of the control curve 10. A sliding bush 25 is mounted in each of the two elongated holes 22 so as to be slidable, so that each elongated hole 22 forms a sliding bearing for the sliding bush 25. The sliding bushes 25 each have a central cylindrical through-hole 26 which serves as a rotary sliding bearing for the tumble shaft 3. On the outside, the sliding bush 25 has recesses 27 in the upper and lower parts (relative to the use position of the stamp) in which the edges of the oblong hole 22 are accommodated, so that the oblong hole 22 forms a linear guide for the sliding bush 25 in the working region 23. In the finished stamp, the tilting shaft 3 is mounted movably in a guide 21. The guide 21 is arranged substantially transversely to the displacement direction 28 or printing direction of the actuating bow 6 relative to the housing 5. The guide 21 and the control curve 10 overlap on both sides.

In the stamping position of the actuating bracket 6 relative to the housing 5, the guide 21 (the slot 22, the sliding bush 25 and the through-opening 26) and the control cam 10 form a through-opening on the first side 29 which is accessible from the outside, so that the tilting shaft 3 can be inserted into or removed from the tilting device 1 from the outside in the longitudinal direction 30.

The handling bow 6 is held in the stamp-painting position by a spring element in the support 17 (for the sake of simplicity, the spring element is not shown in fig. 9) and can be moved into the stamping position against the spring force of the spring element. In the stamping position, the support 17 is received in the handle 31 on the upper side of the actuating bracket.

The two sliding bushes 25 form (first) limiting elements in the form of a widening of the leg 15, so that the widening cannot pass over the slot 18 in the housing 5 (as a second limiting element), through which the leg 15 is introduced into the housing 5.

In addition, the slide bushing 25 holds the stamp frame 7 for receiving the stamp in the housing 5 in such a way that a projection 36 oriented towards the interior of the housing snaps into a receptacle 37 provided for this purpose in the stamp frame 7 and is connected thereto. In the manufacture of the turning device 1, the short side walls 38 of the stamp frame 7 are temporarily pressed inwards here.

In the assembled state of the self-inking stamp shown in fig. 3 to 5, the stamp 4 in the form of a letter set is accommodated in the stamp frame 7 and the flipping axis 3 extends through the flipping mechanism 1 (sliding bush 25, control curve 10 and stamp frame 7) and the stamp 4.

The alternative embodiment shown in fig. 6 to 10 functions largely identically to the first embodiment described above. Therefore, to avoid repetition, parts having the same function are denoted by the same reference numerals and reference is made to the above description in this respect.

The most obvious difference between these two embodiments is: an alternative embodiment does not have a stamp frame 7. Accordingly, the slide bush 25 has no projection 36. The stamp 4 is thus held directly by the flipping axis 3. The tilting tongues 41 are guided directly in the impression 4 in the corresponding receptacles 19'.

As can be seen from the sectional views of fig. 9 and 10, the first sliding bush 25 on the first side 29 is through-going to the tumble shaft 3; the second sliding bush 25 on the second side 32 has a stop 33 for the tumble shaft 3 inserted in the longitudinal direction 30. In addition, the second sliding bush 25 has a connecting element 34 in the form of a catch for establishing a snap connection with the tumble shaft 3 received therein, more precisely with an annular groove 35 in the tumble shaft 3.

The alternative embodiment shown in fig. 11 functions largely the same as the embodiment just described. The difference with this embodiment is that the tumble shaft 3 is connected with the stamp 4 by means of a snap connection 43 and is thus fixed against movement in the longitudinal direction 30 of the tumble shaft 3. In contrast to fig. 9, the turning device 1 in fig. 11 does not have a character module, but has a stamp 4 in the form of a text panel carrier with recesses for the character module.
