Description

The invention relates to a color memory unit for hand stamp, with a holder in which a storage body is arranged, and with a frame in which an impression plate is arranged, wherein the frame sits in a provisional mounting position on the holder, in which the storage body and the impression plate are kept apart from each other, and the frame is in a final mounting position on the bracket can be transferred, in which the storage body and the impression plate abut each other.

The invention further relates to a hand stamp with such a color memory unit and with an actuating unit for moving the impression plate arranged in the holder of a retracted in a housing rest position into an impression position.

Prior art pre-inked or "pre-inked" hand punches with a color memory unit are known in which a so-called flash system is used for the production of an impression plate with an individually adaptable impression pattern, which is based on one for the formation of the impression plate exposed open-cell foam body short-term exposures ("flash" or light flashes) suspend. The flashes of light cause the pores of the foam body to close in those areas where no stamp imprint is to be produced, the imprint plate being used together with a foil having the stamp pattern to obtain the desired stamp pattern in an exposure machine. In order to supply the impression plate with stamping ink, usually a separate storage body is provided, which is impregnated with stamping ink. Such a handstamp is for example in the AT 503 112 B1 described.

From the European patent EP 1 805 032 B1 a hand stamp is known in which the impression plate is formed by an exposed foam body. The impression plate and the storage body are each arranged in a separate frame or holding part, these parts in a preliminary Position are inserted into one another such that the impression plate and the storage body are spaced apart to form an air gap. The impression plate is fixed by means of warts projections in their frame part, which prevent; that the impression plate comes into contact with the storage body. During the exposure process in an exposure machine, the frame parts are arranged between a pressure plate and a glass plate. Applying a contact pressure, the parts are pushed together into a final position in which the impression plate and the storage body are in contact for the exchange of stamping ink. A disadvantage of the color storage unit shown is the fixed attachment of the color memory in its holding part by gluing, since the adhesive bond can dissolve in operation or a bond when using certain plastic materials, such as polypropylene, etc., for the holding parts is not or only inadequately possible.

In the US 2009/0101032 A1 a different self-inking hand stamp is described, in which the stamp unit is present in a single mounting position. The stamp has a stamp housing, in which a coupling part is arranged with two refill nozzles, which is pressed upon actuation of a handle portion on a color memory, which bears against a stamp plate. As a stamp plate an exposed foam is provided, which forms the desired stamp pattern. For fixing the color memory in the single mounting position projections are arranged on the underside of the coupling part, which penetrate into the color memory.

In the DE 697 05 913 T2 a further stamping device is described, which provides only a single mounting position. The stamper has a stamper plate which is longitudinally fixed by a pair of claws elastically engaged with the stamper plate.

The DE 699 09 391 T2 describes a stamp unit with a skirt portion, a holder which is slidably disposed within the skirt portion, and a stamp material which is pressed upon actuation of a handle portion against a punch sheet. The holder has bending sections, which the stamp material fix by means of a sealant between them.

From the EP 0 572 218 A2 is a stamp with a peel-off known.

The aim of the present invention is to provide a color memory unit for a handstamp of the initially mentioned type, with which a structurally simple, permanently reliable attachment of the storage body in the holder can be achieved.

This is achieved by a color storage unit according to claim 1 and a hand stamp according to claim 7 according to the invention. Accordingly, the storage body is fixed in the holder by at least one engagement part. The engagement member allows immovable fixation of the storage body in the holder as soon as the engagement member is brought into engagement with the storage body. Advantageously, it is thus possible to dispense with an unreliable adhesive connection. The inventive fixation of the storage body with the engaging member is not subject to any restrictions in the selection of the materials for the holder, as was disadvantageous in the known adhesive joints. In a preferred embodiment, the engagement member at least partially penetrates into the storage body, whereby a frictional and positive connection between the engagement member and the storage body is made. Alternatively, it is advantageous, in particular in the event that damage to the storage body is to be avoided, when the engagement part only causes a local elastic deformation of the storage body when it engages in the storage body and the storage body is fixed in the holder primarily by frictional engagement.

In order to fix the storage body having the holder on the frame in which the impression plate is held, respectively cooperating locking elements are provided on the holder or on the frame, which define a provisional mounting position corresponding first detent position and the final mounting position corresponding second detent position. In the assembly of the storage unit is first the frame on the Holder just plugged in so far that the cooperating locking elements of the frame or the holder snap in the first detent position in which the storage body and the impression plate according to the provisional mounting position spaced from each other or separated by an air gap; for transferring into the final mounting position of the frame is further pushed onto the holder until the locking elements are locked in the second detent position.

In a first preferred embodiment of the invention it is provided that the engagement part is formed by tabs on the holder, which engage in a deformed or bent state in the storage body. Preferably, the tabs are arranged on a wall facing the frame of the particular trough-shaped holder. The tabs are bent when pushing the frame on the holder of the facing portions of the trough-shaped preferably according to the holder frame or bent and pressed into the storage body to fix the storage body in the holder. Of course, it would be conceivable to provide only a single deformable or bendable tab; Preferably, however, at least two arranged on opposite sides of the holder, in particular in each case integrally formed with the wall tabs are provided. In addition, a design is conceivable in which the tabs are arranged on the frame, wherein the tabs are guided when plugging the frame so that they at least partially penetrate into the storage body. Finally, it is also possible that the tabs are pressed for fixing the storage body in the holder by the user manually or with a suitable tool in the storage body.

In another preferred embodiment of the invention, the engagement parts are formed by spacer projections on the frame, which hold the impression plate and the storage body in the temporary mounting position at a distance from each other and engage in transfer of the frame in the final mounting position in the storage body. Accordingly, the distance projections fulfill two tasks: In the provisional mounting position, the distance projections serve to make contact between the storage body and to prevent the text plate by the storage body of the text plate through the air gap separated between the holder and facing abutment surfaces of the distance projections is immovably disposed; as soon as the frame is pushed into the final assembly position, the spacer projections with their contact surfaces first engage in the storage body, so that a fixed arrangement of the storage body in the color storage unit is achieved.

In order to protect the impression plate against damage and contamination as a result of dust particles or the like., It is advantageous if a transparent protective film is provided on the side facing away from the storage body side of the impression plate. By being translucent, the protective film can also be retained on the impression plate during exposure, thereby advantageously preventing the impression plate from being contaminated.

Preferably, the protective film is hood-shaped in accordance with the outer shape of the frame having the impression plate. With the protective film facing away from the storage body side of the impression plate is completely covered, wherein the protective film is pulled up to form the hood-shaped shape over a certain extent along a substantially perpendicular to the pressure plate wall of the frame.

In order to be able to peel off the protective film in a simple manner, it is expedient for the protective film to have a gripping tab projecting beyond an edge of the frame.

In a structurally simple design with low production costs is provided that at least one locking element by two in the transfer direction arranged one behind the other, preferably also laterally offset from each other arranged latching projections and at least one cooperating latching element by a latching hook, preferably a latching projections common to the two snap-in hooks formed is that overlaps one of the two locking projections depending on the detent position. If the locking elements or the frame and the holder are made by injection molding of a plastic material, as this Preferably, the case, manufacturing advantages are achievable with the lateral offset of the locking projections. The said locking elements in the form of locking projections or latching hooks can be combined with each other in various ways; For example, each locking projection may be assigned a separate latching hook. Preferably, the latching projections are provided on the holder and are overlapped by a single, correspondingly wide latching hook on the frame. It is also conceivable to exchange the position of the latching projections or of the latching hook, so that the latching projections on the frame and the latching hooks are arranged on the holder or is.

The hand stamp according to the invention with the actuation unit for moving the impression plate arranged in the holder from the rest position withdrawn in the stamp housing into the impression position is characterized in that the storage body is fixed in the holder by at least one engagement part. For avoidance of repetition, reference may be made at this point to the explanations in connection with the color memory unit according to the invention.

In known hand stamps of the present type, it has been observed that the contact pressure with which the text plate and the storage body are pressed together during the exposure and after that is unevenly distributed due to unevenness in the text plate, etc., resulting in poor saturation at certain points of the text plate Color can lead. In order to remedy this problem known flash hand stamp and to allow uniform pressurization of the impression plate, it is advantageous if separated on the side facing away from the storage body of the impression plate, optionally separated by the transparent protective film, in particular soft-elastic pressure plate, for example made of polyurethane foam , is provided. The soft-elastic pressure plate causes over the entire surface of the pressure plate a constant contact pressure is exerted and thus ensures a sufficient impregnation of the pressure plate with color from the storage body. It has proved to be particularly advantageous if the pressure plate over the duration of the exposure process beyond a certain period of time, for example for a total of ten minutes, to which the impression or text plate is pressed to ensure complete saturation.

For compact, protected arrangement of the individual components of the color memory unit, it is advantageous if a cover is arranged with the interposition of a protruding paper strip on the side facing away from the pressure plate side of the press plate. The paper strip can also serve as an indicator that the storage unit has not yet undergone any impregnation. After sufficient ink pickup from the impression plate, the paper strip can be removed to indicate that the color storage unit is ready for use in making an impression.

Fig. 1 shows a pre-inked hand stamp 1 with a (stamp) housing 2 and an actuating unit 3 of known per se structure, szB the AT 503 112 B1 , At the bottom of the housing 2, a cover 4 is fixed, with which a color memory unit 5 received in the interior of the housing 2 is protected, which has an impression plate 7 supplied with ink by a storage body 6. The hand stamp 1 is in a state ready for delivery, which is indicated by a arranged on the inside of the cover 4, laterally protruding from the housing 2 paper strip 8.

In order to take the illustrated hand stamp 1 in use, the cover 4 and a temporarily mounted in the housing 2 pressing plate 9, which will be further explained below in connection with the production of the impression plate 7, must be removed.

For transferring the impression plate 7 from a retracted in the housing 2 rest position in an impression position, the actuator unit 3 is locked to a latched with an inner connecting part 10 handle member 11 against the action of a (in Fig. 1 not shown) shifted spring downwards. On a detailed explanation of the actuating mechanism for making an impression on a stamp surface can be omitted here, and it is instead on the AT 503 112 B1 referenced, in which the interaction of the individual parts of the actuator unit 3 is described in detail.

In the case of the pre-inked hand stamp 1 according to the invention, a flash, ie flash exposure, is provided for producing an individual stamp pattern on the impression plate 7. In this case, the color storage unit 5 is placed under arrangement of acting as a template film (not shown) as known per se in an exposure machine and exposed for example for one or two minutes flashes with which the desired stamp pattern in the impression plate 7 by partial melting is impressed. In order to adequately saturate the impression plate 7 with ink in all areas, uniform pressurization of the color storage unit 5 during and after the exposure is required. For this purpose, with the hand stamp 1, as already mentioned, the existing example of a soft elastic polyurethane foam material pressing plate 9 is provided, which is arranged in the housing 2 of the hand stamp 1, between the cover 4 and the impression plate 7, after the exposure process the Impression or text plate 7 firmly and evenly for a few more minutes to press against the storage body 6.

For the formation of the stamp pattern in the impression plate 7, it is necessary that before the exposure, a saturation of the impression plate 7 with color from the storage body 6 - at least on the front - is avoided.

For this purpose, the color storage unit 5 is transferable between a preliminary mounting position in which the impression plate 7 and the storage body 6 are spaced from each other, and a final mounting position in which the impression plate 7 is in contact with the storage body 6.

Like from the FIGS. 2 and 3 can be seen, the color memory unit 5 a trough-shaped holder 12, in which the storage body 6 is received; the impression plate 7 is held in a frame 13 corresponding in shape. Fig. 2 shows the preliminary mounting position of the color memory unit 5, in which a substantially perpendicular to the pressure plate 7 angled wall 14 of the frame 13 is pushed over a certain extent on a corresponding wall 15 of the holder 12, wherein the pressure plate 7 and the storage body 6 through an air gap 16 are arranged separately from each other. For transfer to the in Fig. 3 shown final assembly position, the frame 13 in the direction of arrow A ( Fig. 2 ) completely pushed onto the holder 12 until the impression plate 7 and the storage body 6 abut each other.

In the FIGS. 2 and 3 In addition, in each case an example, transparent, hood-shaped protective film 17 is located above the side facing away from the storage body 6 of the impression plate 7 is arranged. Due to the translucent design of the protective film 17, the protective film 17 need not be removed during the exposure process in the exposure machine. The protective film 17 is bent along the wall 14 from the edge of the impression plate 7 and has on one side a gripping tab 18, which in particular also from the FIGS. 14 and 15 is apparent.

In the prior art, the task of a secure attachment of the storage body 6 in the holder 12 has been solved inadequately so far. Fig. 4 schematically shows a holder 12 according to the prior art, in which the storage body 6 is fixed by means of an adhesive connection 19 on the support or bottom surface of the holder 12.

To avoid such caused by the adhesive bond 19 problems, especially a permanently unreliable attachment or a restriction in the selection of usable for the preparation of the holder 12 materials, at least one engagement member 20 is provided in the holder 12 according to the invention to the storage body. 6 reliable to fix in the holder 12.

From the FIGS. 5 and 6 a first embodiment of the invention is shown, in which as an engaging part 20 opposite to the longitudinal sides of the support wall 15 tabs 21 are arranged, which are made of a deformable material, in particular a plastic material. When inserting the storage body 6 in the holder 12, the tabs 21 are deformed or bent, as shown Fig. 6 is apparent. In the deformed or bent state, the tabs 21 engage in the storage body 6 in order to prevent the storage body 6 from falling out of the holder 12. In the preferred embodiment shown, the tabs 21 are integrally formed on the frame 13 facing the top of the support walls 15, wherein the tabs 21 depressed when pushing the frame 13 in the final mounting position of the frame wall 14, bent and into the storage body 6 are pressed. In order to facilitate this, a chamfer 21 'is provided on the wall 15 adjacent to the attachment point of the respective tab 21.

The Fig. 7 to 10 show an alternative embodiment of the engagement member 20 for fixing the storage body 6 in the holder 12; More specifically, here are several (eg, four pairwise provided) engaging members 20 formed by spacer projections 22 on the frame 13.

FIGS. 7 and 8 each show a sectional view of the color memory unit 5 in the region of a particular also from Fig. 10 apparent pair of opposing distance projections 22 which are formed on the inner surfaces of the longitudinal sides of the frame wall 14. In the in Fig. 7 shown provisional mounting position, also called intermediate position, the storage body 6 is held by the spacer projections 22 at a distance from the impression plate 7 to prevent accidental impregnation of the impression plate 7 with color from the storage body 6 in the provisional mounting position. When the color storage unit 5 is manually or automatically (by closing the lid of the flash machine) in a flash / exposure machine in the final mounting position (s. Fig. 8 ) is transferred, the spacer projections 22 engage in the storage body 6, so that the storage body 6 is fixed in the holder 12. The spacer projections 22 are formed as comparatively narrow, rib-shaped projections; like out Fig. 10 it can be seen, the intended for engagement in the storage body 6 end portion of each spacer projection 22 in the direction of the storage body 6 towards a cut-like tapered, whereby the intervention in the storage body 6 is facilitated.

How further from the FIG. 9 to FIG. 12 (as well as partially off FIGS. 7 and 8 ) can be seen, are for fixing the frame 13 on the bracket 12 in the intermediate position ( Fig. 7 . 11 ) or in the final assembly position ( Fig. 8 . 12 ) Locking elements 23 are provided. As latching elements 23 on the one hand latching hooks 24 are provided, which are arranged on longitudinal inner surfaces of the frame wall 14 and each project beyond the edge of the frame wall 14. The latching hook 24 are each two offset to each other, outside of the support wall 15 arranged latching projections 25, 25 'of the holder 12 assigned. The latching projections 25 define a first latching position, the intermediate position, and the latching projections 25 'a second detent position, the final mounting position, firmly. In the provisional mounting position (intermediate position), the holder 12 and the frame 13 in the particular of Fig. 11 apparent first detent position of the locking elements 23 snapped together, in which the locking projections 25 are overlapped by the latching hooks 24; for transfer to the final mounting position according to Fig. 12 the frame 13 is further pushed in the direction of the arrow A on the holder 12 until the second detent position of the locking elements 23 is reached, in which the staggered locking projections 25 'are overlapped by the latching hooks 24, s. Fig. 12 , The width of the latching hook 24 is designed to allow overreach of both the latching projection 25 in the first detent position and the not only laterally but also in Aufschiebrichtung latching projection 25 'in the second detent position by the common latching hook 24. Of course, it would also be conceivable, instead of a common latching hook 24 separate latching hooks, one for each of the latching projections 25, 25 ', provided on the wall 14 of the frame 13. Also number and type of cooperating locking elements 23 can be varied.

The Fig. 13 to 15 essentially show the one Fig. 7 to 12 corresponding color memory unit 5, but in which a modified embodiment of the frame 13 is provided. As in particular from Fig. 13 can be seen, in this embodiment of the frame 13, each locking hook 24 has a locking bar 26 which is flush with the edge of the frame wall 14 facing away from the impression plate 7 in the assembled state of the color memory unit 5. The locking of the locking elements 23 in the provisional mounting position, as in the FIGS. 14 and 15 shown, or in the final mounting position is analogous as in connection with the Fig. 7 to 12 explained embodiment by the locking projections 25 in the first and the locking projections 25 'in the second detent position of the locking strips 26 of the latching hooks 24 are engaged behind.

How further from the FIGS. 14 and 15 can be seen on the frame 13 - in which the impression plate 7 is added - the hood-shaped protective film 17 is placed, which is transparent and during the exposure of the impression plate 7 may remain in place.

Fig. 16 Finally, the individual parts of the color memory unit 5, namely the holder 12, the storage body 6, the impression or text plate 7, the frame 13 and the protective film or hood 17, in exploded view.

As engaging parts 20 for holding the storage body 6 in the holder 12, for example, in the region of the locking projections 25, 25 'given, inwardly projecting wall portions 27, which also run slightly obliquely and so can be "undercut", or - optionally in addition - separate , For example, hook-shaped engaging parts 20, according to Fig. 16 are formed by way of example in the corner regions of the holder 12.
