Description

The invention relates to a hand stamp, as described in the preamble of claim 1, and an attachment of a hand stamp according to claim 4.

Handstamps in which a stamp plate can be adjusted between an inking position resting on an ink pad and an imprinting position in contact with the surface to be stamped are sufficiently known from the prior art. Such a stamp is for example in the WO 03/099572 A1 the applicant described in more detail.

From the DE 145 899 C1 is a self-inking pocket stamp with a hinged by a rack and pinion punch plate known. The rack drive, the axis, the stamp plate, a color pad and a return spring this pocket stamp are enclosed by an outer tube. This outer tube can be closed by a lid, which can be fixed by means of a bayonet lock on the axis of the stamp plate protruding outwardly through the tube. In the fitted state of the lid, the lower part of the tube is covered edge-like from the outside with two bayonet slots.

Furthermore, the WO 2004/060685 A1 a hand stamp of Selbstfärbetyp, with a comprehensive the lower part and fixable on the outside of the upper part of the stamp cover known. The attachment of the cover to the upper part of the hand stamp takes place by means provided on the upper part Fixierstiften.

From the US 5,377,599 A , of the GB 2 226 276 and the GB 2 293 138 A an attachment for a hand stamp with an approximately plate-shaped cap and a coupling element is known, wherein the cap is placed on an underside of a lower part of the hand stamp and the coupling part extends in the mounted state in the lower part or a cavity enclosed by this.

In the EP 0718111 A a stamp of another type is shown, in which case a so-called pre-ink stamp is shown, in which the ink seeps through the text plate. Such stamp need no turning mechanism for the stamp plate, but the stamp plate is only horizontally moved in a stamping operation. A closure cap is attached in such a way that it is inserted into the interior of the lower part and thereby encloses a part of the stamp frame, for which purpose the stamp is in the rest position.

Furthermore, covers for stamp devices are known from the prior art, which can be placed on the downwardly open lower part in which the stamp plate is adjustable. A stamp with such a cover is from the WO 97/22478 A1 known. The cover is substantially U-shaped and has a bottom plate and the broad side walls of the lower part comprehensive side walls, wherein on an upper end side region of the side walls of the cover snap elements are arranged with a strip-shaped projection on the adjustable upper part in a transport or storage position can be brought into engagement and mutually fixable.

Although in a stamp with such a cover a reduction of the volume claimed by the stamp during transport and storage of the stamp allows, however, there is a high cost of materials for the formation of the side walls in the production of the cover and it takes the cover on its own by the U-shaped configuration a large volume of space to complete. Furthermore, there is the danger that the coupling connection is unintentionally released from the outside by unwanted contact or by a foreign body contact from the outside and the upper part is automatically returned by the acting spring force in an initial position by the coupling between the upper housing part and the cover. This may optionally be done by the transport of the stamp with locked cover by acting on the housing blows or by unintentional user touches. An unwanted unlocking of the stamp from the transport or storage position can lead to pollution of the environment by stamping ink and it may be damaged by the forces occurring in the sudden upward movement of the spring-loaded housing upper part damage to the hand stamp or to this adjacent objects occur.

From the WO 01/83227 A1 a hand stamp is shown, in which individual components are connected to one another via snap connections. This ensures that a quick and easy assembly of the hand stamp is achieved because the items only need to be plugged together

The object of the invention is to provide a hand stamp and an attachment of a hand stamp, which can be produced with less effort and have a simple or compact design, at the same time a reliable attachment of the displaceable upper part or a punch plate carrier of the hand stamp in a transport and storage position should be guaranteed.

The object of the invention is achieved by the reproduced in the characterizing part of claim 1 features independently.

The resulting advantage lies in the fact that the upper part does not have to be specially locked by the coupling of the punch plate carrier to the essay on essay, whereby a gripping the side walls of the base by the essay for coupling the attachment to the upper part is not necessary. The article is thus produced with less material and cost, with the volume claimed by the article per se space can be kept very low. A locking of the punch plate carrier can be carried out in the cavity of the lower part, whereby a very reliable fixation of the punch plate carrier in the transport or storage position is made possible because the coupling region between the punch plate carrier and the article from the outside is not or only with difficulty accessible and inadvertent contact and Cancellation of the lock by foreign contact is hardly possible.

The variants described in claims 2 and 3 are advantageous because the cavity in the lower part can be closed by placing a plate-shaped cap on the underside of the base, and pollution of the environment is prevented by the located in transport or storage position stamp plate. Due to the plate-like design of the cap proves to be compact in structure and in the production cost and it results from the attached to the bottom plate of the cover coupling means a surprisingly easy way to fix the recording plate carrier.

Another, independent solution of the object according to the invention relates to an attachment of a hand stamp according to the features of claim 4. The advantages resulting from this can be seen from the preceding and following description.

Also, the location information chosen in the description, such as top, bottom, laterally related to the immediately described and illustrated figure and are to be transferred to a new position analogously to a new position.

In the Fig. 1 and 2 a possible embodiment variant of a hand stamp 1 is shown, which has a punch plate carrier 2 for a stamp plate 3, which is motion-coupled with an adjusting device 4 for vertical adjustment.

The solution according to the invention is not limited to the illustrated embodiment of the hand stamp 1, but rather all, the expert from the Prior art known hand stamp with vertical adjustment mechanism in combination with the stamp plate carrier 2 according to the invention are executed. The adjustment device 4 can force an exclusively translatory movement or, in a preferred embodiment variant, a combined translational and rotational movement of the punch plate carrier 2 when actuated.

The material of the punch plate carrier 2 and optionally other components of the hand stamp 1, such as. an article described in more detail later, is preferably selected from the group of plastics and formed for example by polymers such as POM (polyoxymethylene), ABS (acrylonitrile-butadiene-styrene) or PP (polypropylene).

According to the illustrated embodiment, the hand stamp 1 comprises in addition to the adjusting device 4 and the punch plate carrier 2, a housing 5. In this case, the housing 5 is essentially formed by a lower part 6 and an upper part 7 mounted on this, wherein the upper part 7 by an actuating element 8 in the form a handle is executed, which is relatively adjustable relative to the lower part 6. The lower part 6 is formed by a plurality of, in the embodiment shown, substantially plate-shaped side wall parts 9, which enclose a cavity 10, in which the punch plate carrier 2 is vertically adjustable.

The hand stamp 1 is of the self-inking type, in which a Nachtränken the stamp surface of the stamp plate 3 with printer or stamp ink, preferably ink, automatically. For this purpose, an ink-soaked stamp pad 11 is arranged in the hand stamp 1. The arrangement and orientation of the ink pad 11 and the adjusting device 4 in the hand stamp 1 is selected such that an alternate contacting of the opposite relative to the lower part 6 relatively adjustable stamp plate carrier 2 arranged stamp types 12 with the ink pad 11 and a to be printed with the stamp image surface of a medium thirteenth , For example, a sheet of paper, can be done, wherein the stamp image determining stamp types 12 perform a transfer of stamp ink on a surface to be stamped the medium 13.

The particular hood-like upper part 7 comprises the lower part 6 at least in one The upper edge portion 15 of the lower part 6. The upper part 7 and the lower part 6 are telescopically adjustable to each other via a guide assembly 16 of the adjusting device 4. In such, caused by depression relative adjustment of the upper part 7 relative to the lower part 6 of the punch plate carrier 2 experiences in a variant of the hand stamp 1 both a translational movement, as well as a rotational movement, in particular a turning movement and is thereby towards a footprint 17 of the hand stamp. 1 , which is placed on a surface of the medium 13 and a cover, moves. For this purpose, the adjusting device 4 in the hand stamp 1 is assigned a not-described, known from the prior art turn and displacement mechanism for the punch plate carrier 2. In this case, this turning and shifting mechanism establishes a movement connection between the lower part 6 or the upper part 7 and the punch plate carrier 2 such that the latter, starting from its in Fig. 1 shown starting position in which it is in contact with the ink pad, in a pivoted by 180 °, lower position (in Fig. 2 indicated in dashed lines), in which he comes into contact with the pad to be stamped, and vice versa, can be spent.

The adjusting device 4 may further comprise a lock for manual positioning of the upper part 7 and punch plate carrier 2 in a replacement or maintenance position, for example, to make an exchange of the ink pad 11 without pressure loading by the in dyeing order on the ink pad 11 fitting stamp plate 3. The lock can be formed by an accessible on an outer side of the upper part 7 actuating element and an adjustable over this locking pin.

The operation of the hand stamp 1 takes place counter to the force of a return element 18 and a spring, preferably a compression spring. This return element 18 causes an automatic return of the hand stamp 1 in the in the Fig. 1 shown inactive or coloring order in which the stamp plate 3 and the punch plate carrier 2 is in contact with the ink pad 11 and exerts a defined contact pressure on the ink pad 1. The punch plate 3 is thus mounted on the turning and sliding mechanism in the hand stamp 1 limited translational and limited rotational in a parallel to the direction of actuation - arrow 19 - the actuating element 8 extending shaft or channel-like cavity 10 in the lower part 6 adjustable. In particular, there is a forced movement coupling between the upper part 7 and the punch plate carrier 2. This cavity 10 can - especially depending on the shape of the die plate 3 and the punch plate carrier 2 - square, for example rectangular or square, or oval or circular cross-section exhibit. The lower part 6 of the housing 5 is thus hollow or frame-like and also serves to guide the stamp plate 3 and the punch plate carrier 2 within the frame-like or in the form of a hollow prism or chute formed housing fifth

The stamp plate carrier 2 is, as stated above, movably supported by the adjusting device 4 within the cavity 10 delimited by the housing 5, the stamp plate carrier 2 for this purpose being a side bearing 21, each in a bearing 20 of an actuator or in the upper part 7, 22 of the punch plate carrier 2 arranged axle journal 23 has. The axle journals 23 extend on the side regions 21, 22 in each case in the direction of the nearest side wall part 9 and protrude over a dimension into the side wall parts 9 of the lower part 6. For this purpose, the side wall parts 9 each have a substantially slot-shaped guide recess 24 for the formation of vertical guides. In the region of the guide recesses 24, the axle journals 23 are coupled in motion to the upper part 7 or inserted into the bearing 20, the upper part 7 being adjustable at least in a linear direction substantially perpendicular to the contact surface 17, as shown by the arrow.

The hand stamp 1 has at least one attached to a bottom 25 of the lower part 6 or attachable attachment 26, which has at least one coupling element 27 for holding the upper part 7 and the punch plate carrier 2 in a transport or storage position. In the transport or storage position of the punch plate carrier 2 and the upper part 7 at least over a portion of an adjustment from the inactive or Selbstfärbestellung in which the punch plate carrier 2 and the upper part 7 are at a top dead center of the adjustment moves. In the transport or storage position, the stamp plate carrier 2 and the upper part 7 are preferably located substantially in an impression position in which the stamp plate carrier 2 is arranged at a bottom dead center of the adjustment path in the cavity 10 of the lower part 6 is. In the transport or storage position of the hand stamp 1 takes by the telescoping superimposition of the upper part 7 on the lower part 6 thus a small volume of space, wherein in the transport or storage position, the hood-like upper part 7 over about a height 28 of the lower part 6 may be postponed to this, whereby the hand stamp 1 assumes its lowest possible volume of space. An overall height 29 of the hand stamp 1 decreases in the transport or storage position by an adjustment 30 of the upper part 7 and the punch plate carrier 2. In Fig. 2 the adjustment path 30 is shown with reference to the axle journal 23 or upper part 7 of the punch plate carrier 2, which is located in the transport or storage position and indicated in dashed lines.

For a better understanding of the invention it should be noted that the hand stamp 1 and the at least one attachment 26 in mutually coupled transport or storage position form a space-saving assembly unit, which is optionally assembled before the attachment of a stamp plate 3 and / or the inking of the stamp pad 11, in order to make the most efficient use of the storage space when transporting the hand stamp 1 to a further assembly location where, for example, the stamp plate 3 is manufactured and placed on the stamp plate carrier 2, or to allow a point of sale. Furthermore, an already assembled hand stamp 1 with stamp plate 3 and ink-saturated inkpad 11 can be carried by a user without risk of contamination, for example, be inserted into a clothing bag by the optionally cap-like attachment 26 the cavity 10 is fixed to the lower part 6 closing.

Like from the Fig. 1 to 4 it can be seen, the stamp plate carrier 2 at least one engageable with the coupling element 27 of the attachment 26 element 31, via which the punch plate carrier 2 on the attachment 26 is releasably lockable. Furthermore, the punch plate carrier 2 may be assigned an additional element 31 for its lockability. The punch plate carrier 2 is preferably automatically or automatically locked on reaching the top of the lower part 6 on reaching a certain adjustment travel 30, in particular the maximum displacement 30 in the region of bottom dead center 26, without manually by a user a locking mechanism must be operated This is done in particular by the deformation of elastically yielding parts of the coupling device 27. The coupling between the coupling device 27 and The element 31 of the punch plate carrier 2 can be released by applying a peel force exceeding the holding force, so that the cap 26 can be pulled off from the lower part 6 under elastic deformation of the coupling device 27. Furthermore, an unspecified, actively operable decoupling mechanism can be provided, via which the coupling device 27 can be released manually by a user.

The element 31 of the punch plate carrier 2 is preferably formed by one of the axle journals 23, via which the punch plate carrier 2 is motion-coupled to the upper part 7. The axle journal 23 may be integrally formed with the rest of the body of the punch plate carrier 2 and formed as a stub, or it may be the axle pin 23 by opposing Stirnendbereiche its own pivot axis, for example, extends continuously between the two side portions 21, 22 of the punch plate carrier 2 , educated.

Embodiments of the hand stamp 1, in which the element 31 of the punch plate carrier 2 is formed by a portion of the body of a known stamp plate carrier 2 or in which the element 31 by its own and automatic latching, snap or friction element, for example, by a resilient tongue, a projection or a depression on the punch plate carrier 2 is formed, wherein the element 31 corresponds to the coupling device 27 of the attachment 26. According to the invention, a latching or snap-on arm of the attachment 26 surrounds a longitudinal side edge 32 of the punch plate carrier 2 and / or a front side edge 33 of the punch plate carrier 2 in the transport or storage position. Furthermore, knob-shaped or strip-shaped projections or depressions on the side wall of the punch plate carrier 2 can be brought into engagement with corresponding recesses or projections in the attachment 26 for detachable coupling.

How best of the Fig. 3 it can be seen, in a possible embodiment of the hand stamp 1, the cap 26 is formed by a substantially plate-shaped cap 34, on which the coupling element 27 of the punch plate carrier 2 is arranged, wherein the coupling element 27 on a top 35 of the cap 34 attached lower part 3 (see Fig. 1 and 2 ) is facing. The coupling element 27 extends from the attached to the bottom 25 of the lower part 3 cover 34 via a height 36 in the lower part 3 and the enclosed by this cavity 10th

In a further embodiment, not shown, two or more attachments 26 may be attached to the lower part 6 independently and detachably, the attachments 26 being inserted, for example, on the underside 25 or on lateral areas of the side walls 9 in such a way that at their coupling elements 27 the elements 31 of the punch plate carrier 2 can be coupled. In such an embodiment, the cavity 10 on the bottom 25 of the lower part may not be completely closed by the attachments 26 and at least partially accessible or opened.

As in particular in the Fig. 4 is shown in the opposite, narrow side wall parts 9, in which the guide recess 24 is arranged, in which the axle pin 23 is guided vertically, arranged on the contact surface 17 of the lower part 6 extending in the direction of the upper part 7 material recess 37, so that the guide recess 24 is open at the bottom part 3 down. The coupling element 27 is preferably arranged on opposite side regions 38, 39 of the covering cap 34, the coupling elements 27 being received in the guide recess 24 via the material recesses 37 in a bottom-side end region 40 of the lower part 3. The at least one coupling element 27 is preferably formed by a latching or snap arrangement 41, wherein the latching or snap arrangement 41 can be formed by two resiliently flexible, in particular cantilevered, holding arms 42, 43, between which a receiving recess 44 is formed the axle journal 23 of the punch plate carrier 2 can be releasably locked in a latching position.

The retaining arms 42, 43 may be arranged within a wall thickness 45 of the side walls 9 in the material recess 37, wherein the material recess 37 may be formed, for example, as a rectangular or circular segment-shaped cutout or opening 46 in the corresponding side wall 9. A width 47 of the opening 46 preferably exceeds a width 48 of the slot-shaped guide recess 24, so that the retaining arms 42, 43 of the latching or snap arrangement 41 can be arranged in the aperture 46 and the guide recess 24 in the particular slot-shaped receiving recess 44 between the support arms 42, 43rd can lead. Thus, the journal 23 of the Stamp plate carrier 2 at the bottom dead center of its adjustment 30 in the receiving recess 44 under deformation of the support arms 42, 43 are pressed and held in transport or storage position by snapping back the retaining arms 42, 43.

The element 31, in particular the axle journal 23, of the punch plate carrier 2 is held in the receiving recess 44 via a detent 49 of the coupling device 27, which is deformed via the element 31 for coupling with a sufficient force and finally snaps onto the element 31. The latching lug 49 or the component comprising this, in particular a holding arm 42, 43, is dimensioned such that the limit holding force from which the coupling connection between the element 31 and the coupling device 27 is released is higher than a restoring force of the return element 18 The receiving recess 44 may be formed substantially as a slot 50 between the support arms 42, 43, wherein the detents 49 in the region of the top 35 by an extent 52 in the direction of the opposite support arm 42; Projecting 43 and a rearing plane of the hand stamp 1 and narrow a width 51 of the receiving recess 44 and the slot 50 each by the amount 52. The latching noses 49 thus form in the direction of the contact surface 17 of the lower part 7 facing retaining surfaces 53, which in coupled to the coupling device 27 or snap-latched position of the element 31 on an outer surface 54 of the element 31, in particular of the journal 23, (in Fig. 5 indicated in dashed lines) and by elastic deformation of the material lying around the detents 49 material, the guideway in the guide recess 24 when needed, especially when removing the article 26 by a user, release.

In the Fig. 5 a further embodiment of the article 26 is shown. This forms in the embodiment shown several locking positions, wherein the article 26, in particular the coupling device 27, for this purpose next to the first detent 49 has a further, in the vertical direction of the first detent 49 spaced detent 55. In the embodiment shown, a convex bulge or expansion 56 is provided in the receiving recess 44 on the coupling device 27 between the latching noses 49, 55, which forms the first latching position R1 for the element 31, wherein above the first latching lug 49 a further expansion 57th or detent 55 is arranged, which after overcoming the first detent 49 forms a further detent position R2 for the element 31.

Furthermore, there is the possibility, not shown, that the further locking lug 55 of the attachment 26 can be coupled to the upper part 7, wherein the upper part 7 for this purpose in the further detent position with the locking lug 55 corresponding locking element, for example, a material return, may have. In the first detent position, the element 31 of the punch plate carrier 2 is coupled to the coupling device 27 in this embodiment, wherein in the further detent position of the upper part 7 is coupled with a detent element to the coupling device 27.

The coupling element 27 can thus be formed by a two-stage latching or snap arrangement 41, whereby the element 31 is held in the vertically above the first detent position lying further detent position in an unexpected release of the element 31 from the lower detent position and the connection reliability of the coupling connection between the element 31 and the coupling element 27 of the attachment 26 is increased. Furthermore, the process of removing the attachment 26 from the base 6 is made easier for a user by the two-stage latching or snap arrangement 41, as a jerky jumping off of the attachment 26 is prevented after release from the first detent position and the attachment 26 in the further detent position safely gripped by the user and can be deducted from the lower part 6.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the hand stamp 1 or of the attachment 26, its or its components have been shown partially unevenly and / or enlarged and / or reduced in size. <B> Reference Numbers </ b> 1 hand stamp 36 height 2 Stamp plate carrier 37 material cut 3 stamp plate 38 page range 4 adjustment 39 page range 5 casing 40 end 6 lower part 41 Latching and snap arrangement 7 top 42 holding arm 8th actuator 43 holding arm 9 Sidewall portion 44 receiving recess 10 cavity 45 Wall thickness 11 inkpad 46 breakthrough 12 stamp Type 47 width 13 medium 48 width 14 print area 49 locking lug 15 border area 50 slot 16 guide assembly 51 width 17 footprint 52 Extent 18 Return element 53 holding surface 19 arrow 54 outer surface 20 depository 55 locking lug 21 page range 56 widening 22 page range 57 widening 23 journal 24 guide recess 25 bottom 26 essay 27 coupling member 28 height 29 total height 30 adjustment 31 element 32 Longitudinal side edge 33 Front side edge 34 cap 35 top
