Description

The invention relates to a self-inking stamp with a housing in which a stamp block is mounted, connected to an actuator movable relative to the housing, wherein the actuator has a latching zone for receiving a hook-and-latch latch on the cover of the self-inking stamp. Furthermore, the invention relates to a method for opening the cover of such a self-inking stamp and the corresponding use.

In order to hold a self-inking stamp, for example, in a compact delivery position (or transport position) with an open stamp plate and at the same time to avoid contamination of the space surrounding the stamp with possible stamp ink adhering to the stamp plate, it is known to use a cover.

For example, DE 69604497 T2 describes a self-inking stamp with such a lid. In the closed transport position, the lid is connected to the actuator via a snap-fit connection between its elastic tab and an outer edge designed as a locking element. To open the lid, the elastic tab must be lifted until it disengages from the edge. To do this, the user grasps the elastic tab on the side facing the actuator.

A more convenient and simple way to open the lid is described in AT 523250 A1. The lids proposed here contain two opposing actuators in the form of buttons. When the buttons, designed as locking spouts, are pressed, the hooks/latches, which latch onto the inside of the actuator, move inward, and the fixed connection between the upper part and the lid is released. The disadvantages are the required mechanics and the resulting complexity of lid manufacturing.

The objective of the invention is to create the possibility of simple and convenient opening of a simple and cost-effective lid.

According to the invention, a self-inking stamp of the type described above is provided, wherein a key is located on the actuator portion for releasing a latch hook latched in the latching zone. The key is movably connected to the actuator portion. The key operates, for example, upon actuation, i.e., when pressed, on the latch hook and moves it relative to the latching zone until the connection is latched. It thereby serves to transmit the force exerted by the user onto the connecting element of the latched connection, for example, the latch hook. This prevents the user from having to directly grasp the latch hook. The key can, for example, move the latch hook, which is connected to the latching zone on the inside of the actuator portion, inward and extend it out of the latching zone.

The latching zone is the portion of the functional element for the detachable, simple, geometrically locked connection of the lid and the actuator (or actuator bracket). The latching zone forms the junction of the actuator. This junction may be, for example, in the form of a projection, recess, groove, or hole. Another portion of the functional element that creates the latching connection is the lid's hook-latch. When creating the latching connection, the hook-latch is elastically deformed and then releasably engages in the latching zone. This connection creates a local connection between the lid and the actuator. Accordingly, the latching zone has a partial contour that ensures engagement of the hook-latch with a corresponding partial contour. It receives, for example, a projection of the hook-latch. The latching connection formed by the latching zone serves to fix the position of the lid relative to the self-inking stamp in general and relative to the actuator in particular.

Alternatively, the latching zone can be provided on the outside of the actuator. In this case, the latch hook can be latched from the outside into the latching zone, simplifying the creation of a latched connection since no parts need to be inserted into the actuator. This also allows for a more compact actuator design since no internal space for the latch hook to move is required.

The key can be designed, for example, as a toggle element. This provides a simple mechanical mechanism for transferring the externally applied force to the key during actuation in the opposite direction, i.e., outward and away from the self-inking stamp, to move the hook-latch, connected to the latching zone on the outside of the actuator, outward from the latching zone and thereby disengaging the latched connection.

In addition to acting on the latch hook, the toggle element may optionally perform other functions, such as serving as a stop to limit the movement of the actuator relative to the housing. Specifically, this can limit movement caused by the force of a spring located between the housing and the actuator. For example, to limit the movement of the actuator, the toggle element may engage or fit into a recess in the housing and, through its connection or support on the actuator and support in the recess, transmit a counterforce between the actuator and the housing. For this purpose, the toggle element may have, for example, a hook-like projection extending toward the housing. The function and design of the toggle element as a stop are precisely and thoroughly explained in AT 522302 A1.

The stopper may be configured, in particular, to limit movement in a first position, which corresponds to a slightly downwardly pressed intermediate position for replacing the ink pad container of the self-inking stamp, and/or in a second position for placing the stamp plate on the stamp plate holder. To replace the ink pad container, the actuator may be fixed in a slightly depressed intermediate position. This lifts the text plate from the ink pad, allowing the ink pad container to move freely, allowing it to be removed, for example, from a side opening in the housing provided for this purpose. To place the stamp plate on the stamp plate holder, it is useful to fix the actuator in a position pushed as far back as possible behind the housing, in which the surface of the text plate protrudes from the impression opening of the housing. Thus, depending on the state of the self-inking stamp, the flip element can perform several different functions, so that no separate measures or parts are required for individual functions.

According to one embodiment, a latching zone may be provided between the housing's impression opening and the flip-flop element. In this case, a portion or extension of the lid's latch hook may be designed such that, when the lid is connected to the stamp, it extends beyond the edge of the flip-flop element facing it and, for example, abuts it. The latch hook thus follows the movement of the flip-flop element and, when pressed, extends outward from the latching zone on the side opposite and remote from the pivot axis of the lid's flip-flop element.

In a particularly compact embodiment of the self-inking stamp, the latching zone may be formed by the edge of a recess in the actuator facing the impression opening of the housing (or the closest edge, or the lower edge in the working position of the stamp), wherein the toggle element is recessed into the recess. The latter may be formed in the form of a notch, opening, or passage in the actuator. If the toggle element simultaneously acts as a stopper or lock, the recess may be formed by a corresponding recess for the stopper, the edge of which facing the lid can thereby form a latching zone, into which the latch hook can engage. The lid latch hook, latched by its lower edge in the recess, can be lifted from the recess and thereby, by rotation of the toggle element, disengaged from the actuator, thereby disengaging the latched connection between the lid and the stamp.

Within the scope of the invention, the actuator may also have two or more latching zones for receiving corresponding latch hooks. In this case, for example, two or more buttons may be respectively assigned to the actuator, each of which can release a latch hook latched in the corresponding latch zone. For example, one button may be provided on two opposite sides of the actuator of the self-inking stamp, which is assigned to a latch zone and is intended to release a latch hook latched therein. Accordingly, the cover of the self-inking stamp may be provided with latch hooks located on each of its two opposite sides. The above-described embodiments and examples may be considered fundamental for each of the two or more or all latching zones, as well as for any attached latch hooks.

The invention also concerns a self-inking stamp, wherein the impression opening of the housing is covered by a lid, which has a latch hook positioned in the latching area of the actuator. The latch hook and, optionally, the entire lid can be made of plastic. This ensures the required elasticity of the latch hook for making and releasing the latched connection. However, other materials are also possible, provided they have the appropriate elasticity.

In addition, the invention concerns a method for opening the cover of a self-inking stamp, wherein the self-inking stamp comprises a housing in which a stamp block is located, connected to an actuator part movable relative to the housing, the actuator part has a latching zone, a hook-latch of the cover is located in the latching zone, and as a result of pressing a key located on the actuator part, the latched connection formed between the hook-latch and the latching zone between the cover and the actuator part is disconnected.

In addition, the invention also concerns the use of a movable key located on the actuator part of a self-inking stamp for opening a lid, wherein the self-inking stamp comprises a housing in which a stamp block is located, connected to the actuator part movable relative to the housing, a hook-latch of the lid is located in the latching zone of the actuator part, and the lid closes the impression opening of the housing.

In Fig. 1-3, a self-inking stamp 1 (or stamp for short) is depicted in its initial position, or inking position. More precisely, this is a self-inking stamp 1 with "upper strike" inking. Stamp 1 comprises a housing 2, an actuator 3, and a stamp unit 4. The actuator 3 is mounted so as to be movable relative to housing 2 in the direction 5 of impression production. The stamp unit 4 is located in the housing 2 and is connected to the actuator 3. The stamp unit 4 includes a plate holder 6 and, as an option, a stamp plate 7 mounted on it. In the initial position shown here, the stamp plate 7 is adjacent to the ink pad 8 in the container 9 for it, as a result of which the stamp ink is transferred from the ink pad 8 to the stencil of the stamp plate 7. To create an impression, the user takes hold of the actuator 3 and sets it in motion by pressing downwards in the direction 5 of obtaining an impression onto the substrate. The user overcomes the force exerted by the stamp spring 10 or the return spring and moves the actuator 3, with its associated stamp unit 4, into the impression position. In this position, the stencil emerges through the impression opening 11 of the housing 2 and transfers the stamp ink located thereon to the substrate. During this process, the stamp unit 4 rotates around the rotation axis 12.

The container 9 with the ink pad can be pulled out of the housing 2 across the rotation axis 12 and across the direction 5 of obtaining an impression, after the actuator 3 has been slightly pressed downwards in the direction 5 of obtaining an impression into an intermediate position (not shown), in which the stamp plate 7 is raised from the ink pad 8. In this intermediate position, the actuator 3 can be fixed relative to the housing 2. For this purpose, stoppers 13 in the form of toggle elements 14 are arranged on both narrow sides 15, 16 of the actuator 3. In the shown initial position or the inking position, the upper side 17 of the toggle elements 14 protrudes outward from the actuator 3, thereby forming keys 18 that are easily accessible to the user. In addition to limiting the movement to the described intermediate position for replacing the container 9 with the ink pad, the stoppers 13 are also intended to limit and fix actuator part 3 in the second position for placing stamp plate 7 on plate holder 6 of stamp block 4.

As can be seen in Fig. 3, the actuator 3 has recesses 19 on both narrow sides 15,16, in each of which a recessed flip element 14 is recessed. Facing the impression opening 11 of the body 2, i.e. the lower edge 20 of the recesses 19 forms on both narrow outer sides of the actuator 3, respectively, a latching zone 21 for receiving a hook-latch 22 of the cover 23 of the stamp 1. These latching zones 21 are thus provided between the impression opening 11 of the housing 2 and the corresponding flip element 14. In order to create a zone for the hook-latches 22, recesses 24 are provided in the recesses 19 between the latching zones 21 and the flip elements 14. The lower edge of the flip elements 14 is located at a greater distance from the lower edge 20 of the recesses 19 than the upper edge 17 of the flip elements 14 from the upper edge of the recesses 19. Inside the recesses 19, passages 25 are provided on both sides, through which hook-shaped projections 26 of the flip elements 14 can fall into the actuator 3, can be inserted into the recesses 27 provided for this purpose in the housing 2 and placed in them to limit the movement of the actuator 3 relative to the housing 2 in one of the positions described in detail above.

Below the latching zones 21, i.e., between them and the impression opening 11 of the housing 2, on the outer side of the actuator part 3, one ramp 28 is provided, which, extending from the latching zones 21, correspond to surfaces inclined obliquely inward. The ramps 28 serve to continuously bend the hook-latches 22 outward over a long path when the cover 23 is positioned, before they snap inward in the latching zones 21. Thus, the actuator part 3 in the area of the ramps 28 is narrowed on the lower side, which facilitates the placement and insertion of the hook-latches 22.

In Fig. 4-7 a corresponding cover 23 for the stamp 1 from Fig. 1-3 is shown. The cover 23 has a base or closing surface 29 and on both narrow sides 15, 16 one hook-latches 22. The hook-latches 22 extend generally perpendicular to the closing surface 29. On the wide sides 30, 31 the cover 23 has one side wall 32. The contour of the side wall 32 corresponds to the recess 42 in the actuator part 3 for removing the container 9 with the ink pad (Fig. 11). The hook-latches 22 have a bevel 33 on the inner side facing the closing surface 29. The latter extends from the place 34 of connection of the hook-latches 22 from the closing surface 29 outward. The connection point 34 is the point which, when a snap connection is created between the cover 23 and the stamp 1, is in contact with the corresponding snap zone 21 on the actuator part 3.

The side 35 of the closing surface 29 facing the stamp 1 in the transport position has four guide elements 36, which are provided outside the supporting surface 37 of the housing 2. The guide elements 36 have a bevel 38, which runs generally parallel to the bevel 33 of the adjacent hook-latch 22 and facilitates the insertion and centering of the housing 2 in the cover 23.

In Fig. 8-10, the stamp 1 is shown in the correspondingly centered, placed in the cover 23, and in the initial positions. Due to the centering achieved by the guide elements 36 of the cover 23, the hook-latches 22 on both narrow sides 15, 16 are positioned identically relative to the actuator part 3 and under the ramps 28.

When the actuator 3 is pressed from the initial position in Fig. 8-10 into the cover 23, the hooks-latches 22 are first bent outward along the ramps 28 until they finally snap into place in the snapping zones 21, as soon as the transport position shown in Fig. 11-14 is reached. In this transport position, the impression opening 11 of the housing 2 is closed by the cover 23. Its hooks-latches 22 are positioned in the snapping zones 21 of the actuator 3. As a result of this, snapped connections are created between the cover 23 and the actuator 3 on both narrow sides 15, 16.

The upper end 40 of the hook-latches 22 passes along the lower edge 41 of the toggle elements 14. The keys 18 formed by the toggle elements 14 on the actuator part 3 are thus arranged to release the hook-latch 22 latched in the latching zone 21 in the manner shown in Fig. 14. Fig. 15 illustrates the disclosed method for opening the cover 23 of the stamp 1 described in detail above. As a result of pressing both keys 18 located on the actuator 3 in the form of both toggle elements 14, the hooks-latches 22 of the cover 23 are pressed outward from the lower edge 41 of the toggle elements 14, which leads to the disconnection of the latched connections 39 formed by the hooks-latches 22 and the latching zones 21 between the cover 23 and the actuator 3. Thus, the movable toggle elements 14 located on the actuator 3 are used to open the cover 23.

In the stamp 43 shown in Fig. 16, the latching zones 4 are provided on the inside of the actuator 45. On both narrow sides 46, 47 of the stamp 43, keys 48 are arranged on the actuator 45. Each of them is formed in this example as part of a toggle element 49. In this case, the toggle elements 49 are each mounted movably, in particular with the possibility of rotation, about an axis 50. Within the framework of this disclosure, a specialist can also provide other supports for the keys 48. For example, as an alternative, the keys 48 can be connected by deformable tabs to the side walls 51, 52 of the actuator 45. The toggle elements 49 shown in Fig. 16 act similarly to the toggle elements 14 in the first example, also as stoppers. It is entirely possible to provide, as an alternative, keys without an additional function.

When keys 48 are pressed, hooks-latches 53 of cover 54, latched in latching zones 44, are pressed inward and displaced from latching zones 44 inward until they are separated. In this way, the latched connection 55 between cover 54 and stamp 43 is disconnected, and cover 54 can be removed from it.

In contrast to the section in Fig. 12 for Fig. 13, shown in Fig. 16 the cut does not pass through the middle of the stamp 43, but with a shift parallel to the axis of revolution of the stamp block 56. The hooks-latches 53 can be provided, for example, on both sides of the axis of revolution, so that on the cover 54 on each side 46, 47 two, and a total of four hooks-latches 53 are formed. The body 57 of the stamp 43 has in the area of the hooks-latches 53 recesses 58, which are intended for the temporary reception of the hooks-latches 53 when separating the cover 54. Thus, during the opening process, the cover 54 can be fixed on the body 57 of the stamp 43 until the actuator 45, as a result of the action of the spring 59, is displaced from the cover 54 relative to the body 57 so much that the hooks-latches 53 are released. Furthermore, the facing inner sides of the hook-latches 53 can be designed to fit against the housing 57 with a frictional lock. This arrangement has the advantage that the lid 54 is not thrown away from the die 53 uncontrollably when opened. Furthermore, in this case, the hook-latches 53 simultaneously serve as the guide elements 36 in the first embodiment, namely, the function of centering the housing 57 in the lid 54 when inserted into it.
