Description

The invention relates to a device according to the preamble of claim 1.

In a known device of this type (DE-GM 61 550), the massive adjustment shaft is in a non-displaceable, but rotatably mounted sleeve in the stamp housing, which one Has a longitudinal slot through which the driver of the adjustment shaft protrudes. The adjustment wheels whose

Bores penetrated through the sleeve each have a coaxial lateral ring extension, which is in a corresponding recess of the adjoining dial or the stamp housing protrudes. Since a Such mutual support add manufacturing inaccuracies of the individual setting wheels and to can lead to inadequate prints, a particularly precise measurement of the individual is required Adjustment wheels and compliance with very small tolerances. This need is particularly great if the setting wheels themselves carry the types to be printed on their circumference. The manufacturing effort is correspondingly high and expensive. Such tight tolerances also increase the risk Friction and thus a corresponding abrasion between adjacent setting wheels with it, the again in the extreme case to an undesired entrainment of a setting wheel by the adjacent one Wheel can lead when the latter is coupled to the adjustment shaft and rotated by actuating the shaft will.

The invention is based on the object of eliminating the device of the type mentioned at the beginning to further develop the disadvantages listed so that they are easier to manufacture and in the Can operate more conveniently

The device according to the invention, in which this object is achieved, is characterized by the im characterizing part of claim 1 listed features.

The invention is based on the finding that it is the conventional coaxial side ring suture £> the setting wheels, via which they fix each other in their position, is not required if you have the stamp housing provides itself with a concave bearing surface for the external support of the dials, and that one on a sleeve rotatably arranged in the stamp housing, which must also be slotted, can be dispensed with if one the adjustment shaft itself forms hollow and they on a Arranges storage column.

Now it is known in a modified version (DE-OS 19 66 066), a row next to each other arranged adjusting wheels in a simple manner without such ring projections with respect to each other coaxially to align by being arranged on a common axis fixed to the housing. This execution is, however, associated with the particular disadvantage in terms of manufacturing technology that the Adjustment wheels must be provided with an external toothing, in which a pinion on a separate and Eccentric to be stored in the stamp housing, hollow and displaceable on a stationary pin Setting shaft engages. The pressure bands that carry the types have to be removed from their teeth here the external teeth of the setting wheels are supported. In addition, the adjustment shaft must be relatively be provided in a complex manner with a series of grooves, the spacing of which corresponds to the spacing of the dials are matched and into which a spring-loaded detent that is fixed to the housing jumps

At this point it should be mentioned that a simple hand stamp has been known for a long time (CH-PS 1119 33), in which the cylindrical inner surface of a hollow cylinder is used to support the setting wheels finds from which the adjustment wheels, over which a flexible printing tape carrying the printing types is guided is to be held in a centered position. For the passage of the printing tapes, a stamp

Execution of the hollow cylinder have two slots running parallel to the cylinder axis. As with the The generic device mentioned at the beginning also finds a massive in this hand stamp trained adjusting shaft application, and the guidance of this shaft takes place via the one at its end provided driver itself which is supported in the setting wheels on their inner bore Execution is not only relatively cumbersome and complicated to assemble; she is also with hers Handling is associated with the risk of tilting and jamming, which is greater the further the adjustment shaft has been pulled out of the opening formed by the holes in the adjustment wheels A safe and comfortable actuation is therefore just as little guaranteed when handling this hand stamp as with the previously mentioned stamp in a manually operated label dispenser.

Also known is a hand stamp with a very different structure (US Pat. No. 4,490,831), the three dials includes, over each of which a flexible, printing type-carrying printing tape is guided. In one embodiment This hand stamp is supported by the setting wheels on concave bearing surfaces. Of the Adjustment of the printing tapes when the type to be printed changes is used segment-shaped clamps, which have a partially cylindrical inner surface with a radius of curvature which is the radius of the corresponding adjustment wheel plus the strength of the pressure band. On the outside of the Clamp protruding adjustment pins penetrate slot-shaped openings in the punch housing. By Grasping the adjustment spigot with your fingers and depressing the clamps can be attached to the Bring the pressure band into contact and then swivel it to gradually adjust the Print types attainable. This pressure system of the clamps on the pressure band ensures a firm connection at the same time The adjustment wheel rests on the associated concave bearing surface during the adjustment, and it will prevents the dial from rolling along the concave bearing surface and being offset laterally in the process or even takes off. Since with each swiveling process over the clamps, the pressure band only moves one type can be shifted further, 'is the handling of this stamp in practice due to the lack of the invention Bearing column on which the hollow adjusting shaft for swift rotation of the selected Adjustment wheel is slidably mounted, very cumbersome and time-consuming.

In a further embodiment of the invention, it has been found to be very favorable from a structural point of view, when the stamp frame has a first side plate to which the bearing column is connected, and if the first side plate is further connected to a mounting block having the concave bearing surface.

The first side plate, the mounting block having the bearing surface and the column are expedient molded in one piece from plastic.

From a functional point of view and in terms of easy assembly, it is advantageous if a second The side plate is provided on the opposite side of the concave side from the first side plate Bearing surface having mounting block can be fixed and has a hole in which the adjustment shaft. which is supported with its inner end portion on the column, is slidably mounted.

Each raid is expediently assigned a flexible printing band which carries the printing types and which is included with the wheel is in drive connection. It has proven to be advantageous if the concave bearing surface is part of a mounting block, on one side of which the first side plate and on the other side of which the second side plate is arranged that both side plates the mounting block and its bearing surface, enclose the pressure belts and the wheels between them and that the adjustment shaft passes through the second side plate extends therethrough. To ensure easy assembly and yet sufficient stability achieve, it is advantageous if an in the mounting block formed socket is provided into which a on the second side plate formed projection engages, in particular if in a further embodiment for connecting of the second side plate with the fastening block of the projection engages in the socket.

The setting shaft is advantageously a display device for displaying the selected wheel assigned, which rotates with the adjustment shaft, but is immovably coupled and only together with this can be moved as a unit
