Description

The invention relates to a hand stamp, as described in the preamble of claim 1, and an attachment for 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 axle, the punch plate, a color pad and a return spring of this bag punch are enclosed by an outer tube. This outer tube can be fixed by a cover, which is fastened by means of a bayonet catch on the axis of the stamp plate protruding outward through the tube can, be closed. 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 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.

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 are. 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 undesired unlocking of the stamp from the transport or storage position can lead to pollution of the environment by stamping ink and it may possibly occur due to the forces occurring in the sudden upward movement of the spring-loaded housing upper part damage to the hand stamp or adjacent to this objects.

The object of the invention is to provide a handstamp and an attachment for a handstamp, 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 need to be specially locked by the coupling of the punch plate carrier to the essay on essay, whereby a gripping around 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 embodiment described in claim 2 is 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. The plate-shaped design of the cap proves to be compact in construction and inexpensive to manufacture 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.

By reproduced in claim 3 embodiment variant can be added and fixed in the transport or storage position, which essentially corresponds to an impression or stamp position, with structurally compact and simple means on the cap.

A further, 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.

The invention will be explained in more detail below with reference to the embodiments schematically illustrated in the drawings.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in 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 known to those skilled in the art hand stamp with vertical adjustment mechanism in combination with the stamp plate carrier 2 according to the invention are performed. The adjustment device 4 can, when actuated, have an exclusively translatory movement or, in a preferred embodiment variant, a combined translatory and rotational one

Force movement of punch plate carrier 2.

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 preferably of the self-inking type, in which a subsequent soaking of the stamp surface of the stamp plate 3 with printing or stamping ink, preferably ink, takes place 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 hood-like upper part 7 in particular comprises the lower part 6 at least in an upper edge region 15 of the lower part 6. The upper part 7 and the lower part 6 are telescopically adjustable relative to one another via a guide arrangement 16 of the adjusting device 4. In such, caused by depression relative adjustment of the upper part 7 relative to the lower part 6 experiences the punch plate carrier 2 in a variant the hand stamp 1 both a translational movement, as well as a rotational movement, in particular a turning movement and is in the direction of a footprint 17 of the hand stamp 1, which is placed on a surface of the medium 13 and a cap or the like. 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 via the turning and sliding mechanism in the hand stamp 1 limited translationally and limited rotatably mounted 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 stamp 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. Preferably, the punch plate carrier 2 and the upper part 7 in the transport or storage position is substantially in an impression position in which the punch plate carrier 2 is arranged at a bottom dead center of the adjustment in the cavity 10 of the lower part 6. 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 on this can be postponed, 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 achieved by applying a holding force exceeding the peel force, so that the article 26 can be withdrawn under elastic deformation of the coupling device 27 from the lower part 6. Furthermore, an unspecified, actively operable Entkuppelungsmechanik provided be about which the coupling device 27 is manually releasable 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 regions 21, 22 of the punch plate carrier 2 , educated.

In principle, further embodiments of the hand stamp 1 are possible in which the element 31 of the punch plate carrier 2 is formed by a portion of the body of a known punch plate carrier 2 or in which the element 31 by its own and automatic latching, snap or friction element, which is formed for example by a resilient tongue, a projection or a depression on the punch plate carrier 2, wherein the element 31 corresponds to the coupling device 27 of the attachment 26. For example, a latching or Schnapparm of the article 26 engage around a long 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 and hold. 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 cap 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 are attached to the lower part 6 independently and detachably, wherein the essays 26 are inserted for example on the bottom 25 or lateral areas of the side walls 9 such that the elements 31 of the punch plate carrier 2 can be coupled to the coupling elements 27. 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 axle journal 24 of the punch plate carrier 7 at the bottom dead center of its adjustment 30 in the receiving recess 44 with deformation of the support arms 42, 43 are pressed and held in transport or storage position by snapping back the support 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 latching lug 55 is arranged, which forms a further latching position R2 for the element 31 after overcoming the first latching lug 49.

Furthermore, there is the possibility, not shown, that the further detent 55 of the Attachment 26 with the upper part 7 can be coupled, wherein the upper part 7 for this purpose in the further latching position with the locking lug 55 corresponding locking element, for example, a material recess, 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.

The subject of a further, independent solution may also be the attachment 26, in particular the covering cap 34 for the hand stamp 1, wherein the hand stamp 1 and the attachment 26 may be formed at least partially as described above.

The embodiments show possible embodiments of the hand stamp 1 and the essay 26, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are mutually possible and this variation possibility due to Teaching for technical action by objective invention in the skill of those working in this technical field is the expert.
