Description

This invention concerns a closing cover for a stamp, as well as a stamp for it, as they are described in the restrictive parts of the independent claims 1, 16 and 20 of the claims.

From WO 2016/197172 A1 a stamp is known, in particular a stamp on a stand, which contains at least one stamp component and one printing unit, this stamp component being formed from an upper part, which is made staple-shaped, and a lower part with an element for receiving the pad . The printing unit, by means of a turning mechanism, preferably having a rocker guide, is motionally connected in the lower part to the upper part by means of an axis or axle, and in the initial position the text plate mounted on the printing unit is adjacent to the stamp pad impregnated with stamp ink in the element for receiving the pad . During the stamping process, to create a stamp impression in the stamping position, the printing unit together with the text plate can be moved to the stamping position using a reversing mechanism. Next, there is shown a closing cap which is slid along its narrow side onto the compressed die so that the closing cap is held on a retaining member on the lower body. Said closing cover has a protective surface and two side walls molded to the longitudinal sides, and when the closing cover is pulled on, the internal space of the stamp and the text plate attached to the printing unit are closed by means of these side walls and the protective surface.

From EP 1 796 909 B1 and EP 2 634 005 B1 a closing cap and a hand stamp, in particular a self-coloring stamp, made of plastic are known. Said stamp then consists of an upper part and a lower part, whereby during the stamping process the upper part receives the lower part. In this case, the printing unit with the text plate mounted on it is connected to the upper part by means of a turning mechanism in the lower part, so that during the stamping process, the text plate mounted on the printing unit is rotated by means of the turning mechanism to create a stamp impression.

The closing cover consists of a protective plate, respectively a protective surface and side walls extending around the sides, this closing cover being from below, i.e. from the side of the supporting surface it is mounted on a hand stamp. In this case, said closing cover is connected by means of a clamping device to the axis, respectively, to the journal of the axis of the printed circuit assembly.

In the case of the closing cap according to EP 2 634 005 B1, said closing cap in the pressed state of the stamp is fixed to the printing unit by means of locking elements, the locking hooks being oriented inwards so that it can be fixed to the printing unit, in particular to the text plate holder.

Closing cover systems are also known in which fastening, in particular fixing, takes place on the outer surface of the stamp, in particular on the upper part of a self-painting stamp, as is known, for example, from EP 0 873 245 B1.

For the sake of completeness, it should be mentioned that closing caps are also known for other types of stamps, namely the so-called Flash or Pre-Ink stamps, which in order to close the text plate must always be mounted from below to prevent the ink from drying out on the text plate. Namely, if such a stamp were left without a cap for too long, the leaking ink would cure so that the stamp impression could no longer be used, or only partial areas would be accessible.

The disadvantage of the above-mentioned closing covers is that they can only be pulled off the stamp with increased effort required to remove the fixation. In this case, it may happen that due to deformation of the locking hooks, they come off or can no longer be returned to their original position, and thus the locking cover is no longer securely locked.

The object of the present invention is to provide a locking cap and a stamp therefor, which eliminates the above-mentioned disadvantages and at the same time improves ease of use.

This problem is solved by the present invention.

The closing cover proposed by the invention is characterized in that two opposing actuating elements are located on the outer perimeter of the protective cap, wherein at least one actuating element is flexibly or elastically connected to the protective cap or to the side walls, and each actuating element has at least one locking element. an element, in particular, a locking hook for latching with a spout-shaped locking projection in the internal space, respectively, in the free space of the upper part of the stamp or, respectively, connected to it.

It is advantageous here that, thanks to the use of the actuator, the locking cover can be opened reliably and simply, and at the same time, a secure hold can be guaranteed by the design of the locking hook.

Moreover, with this type of construction, extraction can be carried out without the application of force, since the user first compresses the actuating elements, so that the locking hooks are pressed inward and, thereby, the locking is released from the upper part of the stamp, so that the locking cover can be pulled down without force. A further advantage is that a higher holding force for the locking cap can be achieved, since the size of the locking hooks and therefore the locking surface can be larger, since for insertion or release the locking hook is moved by means of the locking hook actuators, so that possible Effortless insertion and removal.

Known solutions from the prior art do not have any such actuating elements through which the fixing element moves; they are only pressed onto the stamp and pulled away from it. By placing the locking elements on the flexible actuator, a preferably linear movement is achieved, in particular a movement path, so that these locking elements of the closing cap can be disengaged by the movement path of the locking element on the upper part, so that this closing cap can then be efforts to remove the stamp. Thus, this design of the locking elements, in particular the orientation of the locking hook, can occur in a variety of ways, since the release of the locking connection occurs along the path of movement of the locking element. Accordingly, a separate description describes a variety of different orientations of the locking hook on the closing cover: outward, towards each other, against each other, which is fixed in the corresponding locking element, in particular in the locking protrusion.

The advantage is that the locking element, in particular the locking hook, projects outwards, i.e. towards the drive surface of the actuator. This allows the top part to be produced simply by requiring an undercut, in particular a locking edge, to be produced in the free space on the top part, which can be produced simply and economically.

A further advantage lies in the feature that two locking elements with locking hooks directed outwards are arranged on the actuator element. This can ensure that the closing cap is securely held on the stamp.

Preferred features are that the locking element, in particular the locking hook, is oriented parallel to the drive surface of the actuator. Due to this parallel orientation relative to the actuating element, in particular the printing surface, a stable design of the locking element can be ensured.

The advantage is also provided by the characteristics according to which the actuator element has two fixing hooks oriented parallel to the mounting surface, the protruding elements in the form of noses of which are directed towards each other. This ensures an increase in the pulling force, so that the closing cap cannot fall off the stamp as a result of shocks.

Advantages are provided by the feature that a gap is formed between the two locking hooks to receive a locking protrusion of the stamp, in particular a locking protrusion located on the inside of the upper part. This ensures that between the protruding elements in the form of spouts there is a gap for a corresponding fixing element of the upper part, which, when the closing cover is connected to the stamp, fits into it and is thereby fixed.

Advantages are provided by the feature that the protective cap, the side walls and the flexibly actuated actuator are constructed as a single unit, in particular as a single injection molded part. Thanks to this, economical production is possible, since no assembly costs are required when producing the end cap in this way.

Advantages are also provided by the characteristics that between the actuating element and the protective cap, in particular the supporting element, there is free space for deflecting the actuating element that is loaded under pressure, in particular the locking hooks placed on it. Thanks to this, on the one hand, the stamp can be securely pressed onto the support element, and, on the other hand, said actuating elements can move freely without interfering elements in order to effortlessly install or dismantle the closing cover. By pressing the lower part of the stamp onto the supporting element of the closing cap, a certain sealing is further ensured. Furthermore, thanks to this, the text plate mounted on the printing unit, which was just rotated to the stamping position when the closing cap was installed, will be positioned in the compressed state between the supporting elements at a distance from the protective cap, so that in the locked state no printing points are created on the text plate, which occur when the text plate adheres to the part. If, in particular, this text plate were pressed against the workpiece or elements for a longer period of time, the rubber of the text plate could be plastically deformed, so that the quality of the print would be significantly reduced and the text plate would have to be replaced. It is therefore essential that when the closing cap is mounted, the text plate is freely positioned, which is the case with the closing cap according to the invention. In this case, it is also possible that fixing elements are arranged on the supporting elements or supporting surfaces for the lower part of the stamp, so that this stamp is first mounted on the supporting elements and the lower part is fixed to them, so that the closing cover can no longer fall off the lower part , following this, by moving the stamp to the stamping position, said locking hooks of the actuators engage with the upper part and fix it in the stamping position.

A further preferred embodiment is that the locking element, in particular the locking hook, is oriented in the direction of the drive surface on the actuating element, whereby the locking hook is designed to snap into place with a locking projection on the inner surface of the upper part of the stamp. Thanks to this, the locking hook faces outward, and thus, when the closing cap is pressed onto the stamp, the locking hook can be inserted into the free space for the locking hooks and snap into place, so that the locking takes place inside this upper part, i.e. invisible. Further, due to the outwardly oriented locking hook, when the actuating elements are compressed, the locking hook also moves towards the center, i.e. inside the closing cap and can thus simply be separated from the upper part.

A preferred embodiment is in which the actuating element is flexibly connected, in particular in the shape of a wavy line or meander shape, to the protective cap and/or to the side walls by means of a connecting bridge. Due to this, said actuator is moved by means of a corresponding pressure action, accordingly, the connecting bridge is deformed in order to release the fixation, or make this possible. This makes it possible to manufacture the end cap with flexible actuators as a single unit.

A preferred embodiment is in which two actuating elements for actuation with one hand, in particular with two fingers, are arranged oppositely on the closing cover. This allows the user to hold the stamp with one hand and simply remove the locking cap with the other hand. Thus, there is no danger of contamination of the hands due to contact with the text plate, since these fingers are positioned on the outside of the closing cap, and when the closing cap is removed from the stamp, the text plate, in particular the printing unit, is automatically rotated back to the original position of the stamp, so that you can again pick up paint from the stamp pad. Thus, it is impossible for the fingers to come into contact with the text plate provided with the ink. Also, thanks to the opposite arrangement of the actuators, a secure grip between two fingers is ensured.

A preferred embodiment is in which both opposing actuating elements are flexibly connected to the protective cap and/or to the side walls. Thanks to this, by simply pressing with two fingers, both locking hooks can be pulled out of the locking connection and released, as a result of which the locking cap can be reliably detached from the stamp. It is also therefore possible that when the closing cap is placed on the stamp, the locking hooks are displaced relative to each other by pressing, so that the locking hooks can be pushed into the free space of the upper part of the stamp without force. To secure the closing cap, it is then only necessary for the application of pressure on the actuators to be completed, so that the locking hooks move outward again to their original position and come into contact with the locking protrusions in the free space of the stamp. Of course, it is also possible to install or fasten the closing cap without applying pressure, whereby the closing cap is positioned in such a way that the locking hooks can be pushed into the free space of the stamp, so that the closing cap then only needs to be pressed against the stamp without actuating the actuators, accordingly, press down, as a result of which these fixing hooks and actuating elements will correspondingly deflect inward and, accordingly, will be compressed. If the locking hook reaches the locking protrusion, the locking hook can again rotate back to its original position, i.e. now outwards, and thereby snaps into place with the locking tab.

Thus, it is also possible that the closing cap is simply pressed against the stamp, or the stamp is pressed against the closing cap, so that the stamp is compressed, as a result of which the locking elements of the closing cap and the stamp are locked in the free space of the upper part, and thus the stamp is held in in a compressed position with the closing cap attached. Thanks to the flexible design of the connecting bridges for the actuator, it is also prevented that when the closing cover is pressed in with great force, the locking hooks can be safely deflected and will not break off again.

Preferred is an embodiment in which a safety bracket is located in the area of the actuating element, which is connected to the protective cap and/or to the side walls. Thanks to this, when transporting a stamp with a mounted closing cover, accidental opening due to the pressing action of an object on one or both actuators is prevented. This safety clamp is designed in particular in such a way that the user must now consciously grasp the drive surfaces with his fingers in order to be able to compress them. This safety bracket thus forms a so-called barrier against accidental pressure on the actuator.

An embodiment in which one actuator element is provided in the form of a drive surface on the side walls and an opposing actuator element is flexibly connected to the closing cover is also preferred. This also ensures that only the flexible actuator provides a secure hold for the fingers, since the drive surface is provided with, for example, anti-slip protection, in particular grooves.

Preferred is an embodiment in which a safety bracket is located in the area of the actuating element, which is connected to the protective cap and/or to the side walls. This prevents the risk that, for example, when transporting a stamp with the closing cap attached, it can easily come off, since said safety clip protects the actuator from inadvertent force. This safety clip is located in the transition region, respectively, in the corner region of the bottom and side walls of the closing cover. To avoid unwanted operation of the actuators due to foreign objects, for example when transporting in a bag, said actuator is retracted so that the drive surface extends behind the outer surface of the side walls and the safety bracket. Thus, it is necessary to consciously grasp the rearward drive surface with your fingers to operate it.

Preferred is an embodiment in which said or said flexible actuating elements are made from several parts, in particular from a main body and a pressure plate. Thanks to this, both of these parts can be easily produced from different materials and different colors. For example, the pressure plate on which the fingers are positioned when actuating the locking cap may be provided with an anti-slip material for secure handling, while the locking cap itself is made of an economical material. A significant advantage is obtained if both of these parts, i.e. of the closing cover, in particular the protective cap and the side walls are made in a different color than the pressure plate, with black being preferably used for the closing plate, while red is used for the pressure plate. Thus, thanks to the red color, the user can immediately recognize the pressure plates or the pressure plates where the actuators are and can actuate them simply and quickly. This also improves the appearance of the end cap and creates the impression of high quality.

Further, the object of this invention is also solved by means of a stamp device, in which the closing cover is made according to any of paragraphs 1 to 15 of the claims, and on the upper part of the stamp there is a locking protrusion for fixing with locking elements on the actuator. It is advantageous that a closing cover is thereby created, the locking elements of which are moved by means of the actuating elements. In this case, due to this displacement, in particular the linear movement of the locking elements, they are disengaged from the corresponding locking element on the stamps, so that the closing cover can then be removed from the stamp without force. However, at the same time, a very high holding force is ensured in the inserted state, since the locking protrusions can be made corresponding in size to the locking elements, since they are released not only under the influence of force, in particular by pulling the stamp and the closing cover away from each other, but the separation occurs due to the specified displacement of the fixing elements on the closing cover.

Advantages are provided by the characteristics that between the upper part and the lower part of the stamp there is free space for the insertion of fixing elements, in particular the fixing hooks of the closing cover. Thanks to this, the locking of the closing cover with the stamp takes place on the inside of the upper part, so that said fixing elements are protected by the upper part. Further, due to the orientation of the locking projections, the locking elements can be oriented outward or parallel to the inner side of the upper part.

It is also preferable to have an arrangement in which the fixing of the locking hooks of the closing cover with the locking projections occurs between the upper part and the lower part in the free space. Due to this, a specially adjusted locking projection can be formed or arranged on the upper part in order to provide the required or desired holding force for the locking connection.

It is also preferred that the said locking elements on the closing cover are repositionable, in particular, movable along the actuating elements. This ensures that, in order to release the locking between the closing cap and the stamp, said locking elements of the closing cap are disengaged from the locking elements on the stamp, in particular on the upper part, due to the actuation of the actuating elements, after which said closing cap can be removed without force from the stamp.

Further, the problem posed is also solved by means of a stamp, in which on the upper part there is located a free space formed in the direction of the internal space for receiving the locking element of the closing cover, and in the free space there is a corresponding locking element, in particular a locking protrusion for fixing with molded to the closing cover fixing elements, in particular with a fixing hook.

Advantageously, this makes it possible to fix the upper part with the closing cover in the compressed state of the stamp, so that the stamp is held in the compressed state. At the same time, it is ensured that, due to the return force of the spring in the stamp, said closing cap is firmly pressed, or pressed, against the lower part of the stamp, so that a very good sealing and protection against contamination is ensured. The design dimensions of the stamp with the attached closing lid are also reduced, making easier storage, for example in a drawer, or easier transportation possible. The use of a locking cap also ensures that during transportation, accidental compression of the stamp is prevented, which will inevitably lead to contamination of nearby objects with stamp ink, since the stamp is fixed in a compressed position.

And finally, it is preferable to design in which the actuating element of the closing cover, when the closing cover is mounted, is located on the stamp under the lower part, freely accessible. Thanks to this, the user can easily reach the actuating elements, so that the closing cap can be quickly and easily separated from the stamp.

This invention will be described below in the form of embodiment examples, and it should be noted that this invention is not limited to the presented and described embodiment examples.

In FIG. 1 - Fig. 8 shows a closing cover 1 for a stamp 2, in particular for a self-inking stamp 2.

Said stamp 2 contains at least one upper part 3, one lower part 4 and one printing unit 5, and this printing unit 5 is connected or connected to the upper part 3. Next, between the upper part 3 and the lower part 4 there is a spring element 8 for returning to the original position 9, and during the stamping process to create a stamp impression (not shown) the specified printing unit 5 with a text plate 10 attached to it by means of a reversing mechanism 6 can be moved to the stamping position 11, respectively, to the stamping position 11, which approximately corresponds to the transport position, respectively, to the storage position 11 with the closing cover 1 mounted. In the initial position 9, the text plate 10 mounted on the printing unit 5 is oriented in the direction of the element 12 for receiving the pad in the lower part 4, so that when the ink pad 13 is mounted, said ink receiving text plate 10 is adjacent to the ink pad 13 impregnated with ink. This kind of design of the stamp 2 with the corresponding components is already well known from the prior art, so here their interaction , accordingly, the operating principle is not discussed in detail. Furthermore, it is also known that stamps of this kind 2 are equipped with a closing cap 1.

According to the invention, a new type of closing cap 1 will be described below, which can be used preferably on a self-inking stamp 2. In principle, this closing cap 1 can also be used for a so-called pre-ink or flash stamp, if the lower part, respectively, is the receiving part for the pad of the corresponding pre-inc or flash stamp is made corresponding to the closing cover 1, for which purpose the free space is integrated with the locking element, in particular the locking protrusion, as will be explained later. Next, the stamp 2 according to the invention is also described, in particular the so-called self-coloring stamp 2, which is designed to accommodate a closing cover 1, wherein this stamp 2 and this closing cover 1 can be made of any shape, for example round, rectangular, square, oval. In the illustrated embodiment, a round stamp 2 with a round closing cap 1 was selected, so that for other shapes a corresponding adjustment must be made.

The closing cover 1 comprises at least one plate-shaped protective cap 14 or a protective surface 14 with side walls 15 projecting forward in one direction and at least one support element 16 lying inside for inserting or installing the lower part 4 of the stamp 2 Said support element 16 extends in the direction of the forward projecting side walls 15, however, the height 17 of the support elements 16 is preferably less than the height 18 of the side walls 15. It is also possible that the side walls 15 are made of different heights.

Further, on the outer perimeter of the protective cap 14 and/or on the side walls 15 there is at least one actuating element 19, which is flexibly or elastically connected to the protective cap 14 and/or to the side walls 15, and/or to the support element 16. According to this embodiment example, in FIG. 3 shows two actuating elements 19, which are connected to the side walls 15 by means of flexible connecting bridges 20. It is possible that the actuating elements 19 have anti-slip protection on their drive surface 21, which can consist, for example, of grooves, symbols or be made made of a different material so that your fingers can hold it securely.

In order that the closing cap 1 can be connected to the stamp 2, this closing cap 1 has at least one outwardly directed locking element 22, in particular a locking hook 23, this locking element 22 being located on the actuating element 19 or molded towards it and extends in the same direction as the side walls 15. Preferably, each actuator element 19 is provided with at least one locking element 22, in particular one locking hook 23, whereby in the embodiment shown in FIG. 3, the locking element 22 is formed by two locking hooks per actuator 19. However, it is also possible to use only one locking element 22 on one actuator 19, and instead of a second locking element 22 on the second actuator 19, a support element (not shown) is used. which can be located on the stamp or on the closing cover 1. It is also possible that only one fixing element 22 is made flexible due to the flexible actuating element 19, and the second actuating element 19 and the fixing element 22 located on it are made fixed, respectively, rigid, so that only by means of one flexible actuator 19 can the locking connection be released or created.

Preferably, these actuating elements 19 are secured by means of connecting bridges 20 to the protective cap 14 or to the side walls 15 or to the support element 16, and according to FIG. 3, this actuating element 19 is connected to the side walls 15. These two actuating elements 19 are held in position by preferably four connecting bridges 20, these connecting bridges 20 being flexible so that when pressure is applied to the actuating elements 19, they can be respectively displaced or respectively , rearranged, and they always automatically return to their original position. According to this embodiment according to FIG. The 3 connecting jumpers 20 are made in the shape of a wavy line, respectively, in the shape of a meander. Due to this, the thickness of the material of the connecting bridges 20 can be correspondingly large, while, however, the flexibility of the connecting bridges 20 is maintained. However, in order to allow this kind of deformation or movement to occur, between the actuator 19 and the protective cap 14, in particular the support element 16, there is a free space 24 for deflection of the actuator 19, which is loaded under pressure, i.e. when the actuators are compressed elements 19, the specified connecting bridges 20 are deformed in such a way that these actuating elements 19 with molded fixing elements 22 are displaced into the free space 24, respectively, pressed out, so that this free space 24 is reduced, and after the end of the application of pressure, the specified connecting bridges 20 return to the original position, and thus the actuator 19, is again positioned in its original position.

Next, in FIG. 3 it can be seen that all elements, in particular the protective cap 14, the side walls 15 and the actuating element 19, which is flexibly actuated by means of connecting bridges 20, with the fixing element 22 located on it, are made as a single whole, in particular as one single part produced by injection molding. In this way, the end cap 1 can be economically manufactured in one operation without additional assembly costs, preferably acrylonitrile butadiene styrene (ABS) being used as the material.

However, in order to be able to attach this closing cover 1 to the stamp 2, this stamp 2 must have a free space 25 between the upper part 3 and the lower part 4. The size, in particular the length and width of this free space 25 is intended to receive the fixing element 22, and it also has a corresponding locking element 26 inside, in particular a locking protrusion 27. Preferably, the upper part 4 in the area of the free space 25 is slightly curved outward, as can be seen in FIG. 1 and Fig. 2, so that said free space 25 is formed only in these convex areas, that is, the free space 25 is only limited. However, it would be possible to provide an upper part 4 which has a free space 25 along its entire perimeter with a locking protrusion 27 located therein or molded thereto, so that the closing cover 1 can be fitted in any position. Said locking element 26, in particular the locking protrusion 27, is preferably integral with the upper part 4, in particular as an injection molded part.

The fastening of the closing cover 1 can take place in such a way that the closing cover 1 is placed on a flat surface 28, in particular on an office table, after which the stamp 2 is positioned above the closing cover 1 (see FIG. 1) and finally pressed onto closing cover 1, so that the lower part 3 is adjacent to the supporting surface 16 (see Fig. 2). The stamp 2 can then simply be compressed, so that the locking elements 22, in particular the locking hooks 23 from below, are pushed into the free space 25 of the upper part 3 and are accordingly deformed, respectively, pressed downwards until these locking hooks 23 are at the level of the locking protrusion 27 and thereby return to their original position again, so that these locking hooks 23 snap into locking protrusions 27.

To detach the closing cover 1, you now need to take the stamp 2 in your hand so that with the other hand, in particular, with two fingers, you squeeze the actuating elements 19. Thanks to this, the locking hooks 23 move down again, so that the locking with the locking protrusions 27 is released, and the locking cover 1 can be pulled down so that the fixing hooks are pulled out of the free space. It should be mentioned here that when the locking connection between the locking hooks 23 and the locking protrusion 27 is released, the stamp 2 would immediately, under the action of the spring element 8, move to its original position 9, so that the locking cover 1 can simply be pulled off.

In FIG. 4 shows another example of the design of the closing cover 1. In this case, the actuator 19 is now connected to the supporting surface 16 by means of a connecting bridge 20.

In FIG. 5 shows an example of an embodiment in which the actuator 19 is connected by means of a connecting bridge 20 to a protective cap 14 or to a protective surface 14, i.e. with the bottom of the closing cap 1, due to which, when pressure is applied to the actuator 19, said locking element 22 is rotated or tilted towards the center of the protective cap 14 and can thereby be removed from the locking connection. That is, in contrast to another embodiment, the locking element 22 on the actuating element 19 now does not perform any horizontal displacement, but is adjusted by means of a rotary movement.

Next, in FIG. 6 shows an example embodiment in which a safety bracket 29 is installed, which protects the actuating element 19 from accidental application of pressure during transport of the stamp 1. This safety bracket 29 is located in the area of the bottom, respectively, the protective surface 14, so that the specified actuating element 19 is located above. In this case, the safety bracket 29 is connected to the side walls 15 and/or the protective cap 14. It is preferable that the actuating element 19 is not flush with the outer surface of the safety bracket 29, but that these actuating elements 19 are slightly offset back, so that it is necessary consciously position your fingers on the rearward actuating elements 19 to activate them. Due to this arrangement of the safety bracket 29, it turned out that when transporting the stamp 1 in a bag, involuntary opening due to the application of pressure by foreign objects on the actuating elements 19 is prevented. In principle, the design according to FIG. 6 corresponds to the implementation according to FIG. 3 with connecting bridges 20 in the shape of a wavy line, respectively, in the shape of a meander.

In FIG. 7 and Fig. 8 shows the following example of the design of the closing cover 2, in which the actuating element 19 is now made up of several parts, this actuating element 19 being formed from a main body 30 and a pressure plate 31. The main body 30 is again by means of flexible connecting bridges 20, which are now made in an arcuate manner, connected to the side walls 15 or the protective cap 14, while the pressure plate 31 is fixed to the main body 30 of this actuator 19. In this case, the pressure plate 31 is preferably secured by means of a snap connection, so that this pressure plate only needs to be pressed against to the main body 30. For this purpose, one or two locking hooks 33 are located on the rear side 32, which are inserted into corresponding locking holes 34 on the main body 30, and thereby the pressure plate 31 is snap-connected to the actuator 19. The pressure plate 31 now has drive surface 21, so that by applying pressure on the pressure plate 31, in particular on the drive surface 21 of the pressure plate 31, the main body 31 is pressed inward or backward, so that the locking hooks 23 projecting outward on the main body 30 are also moved, and thus In this way, these fixing hooks 23, when attached to the stamp 1, are disengaged, so that the closing cover 1 can be removed.

It is advantageous in this type of design of the actuator 19 with the pressure plate 31 that this pressure plate 31, i.e. the so-called control button may be made of a different material or a different color, so that such pressure plates 31 can be easily perceived by the user. For example, in FIG. 8 shows a three-dimensional image of a stamp 1 with a mounted closing cap 2, in which the pressure plate 31 is red, while the closing cap 2 is black. In this way, it can be seen at a glance where the actuating pressure plates 31 are located, so that the user deliberately grasps these pressure plates 31 between two fingers and applies appropriate pressure to release the locking hooks 23 from the stamp 1 and pull down the locking cover 2.

It can also be said that, although due to the construction of the end cap 2 being composed of several parts, the manufacturing process is correspondingly slightly delayed in installation, however, the ease of handling increases significantly, since color contrast can thereby be easily achieved.

It is also possible that the pressure plates 31 are provided, for example, by laser engraving with words which, when engraved, produce a color change, and thus these words are clearly visible and indicate the positions of the pressure plates 31.

As can be seen in the drawings, the pressure plate 31 is designed in such a way that it covers not only the main body 30, but also the side connecting bridges 20 are covered, so that only these pressure plates 31 and the body of the closing cover 2 are visible from the outside. At the same time, protection is ensured from pollution.

In the embodiment described above, it is essential that a closing cap 2 and a stamp 1 associated with it are created, in which one or two actuating elements 19 are located on the closing cap 2, respectively, which are moved by applying pressure in order to separate the closing cap 2 from the stamp 1. Previous technical solutions from the prior art do not contain any such actuating elements 19, and the covers are only pressed onto the stamp and pulled off from it.

In FIG. 9 - Fig. 16 shows two other examples of a stamping device with a stamp 2 and a closing cap 1 mounted on it, which uses, respectively, a variable arrangement of the fixing connection between the stamp 2 and the closing cap 1.

According to the invention, as before, the closing cap 1 is provided with at least one, preferably two, flexible actuating elements 19. These actuating elements 19 are located opposite each other on the closing cap 1, so that this closing cap can be clamped or held between two fingers one hand so that stamp 2 can be held with the other hand.

However, in order to connect both components, i.e. closing cover 1 with a stamp 2, this closing cover 1 is preferably placed on a flat surface, in particular a desk, and then the stamp 1 is pressed onto the closing cover 1, in particular onto a support element or support surface, and snaps into place in the process stamping, while the disconnection or removal of the closing cover 1 preferably occurs in such a way that the stamp 2 is held in one hand and the closing cover 1 is held by both actuating elements 19 between two fingers, in particular the thumb and index finger of the second hand, and By applying pressure to the actuators 19, this locking connection is released so that the closing cap 1 can be pulled off the stamp 2.

In this new embodiment, the structure of the main body of the closing cover 1 is correspondingly the same as the above-described embodiments in FIGS. 1 - Fig. 8, in particular with the implementation of the protective surface 14, the side walls 15, the supporting surface 16, the driving surface 19 of the connecting bridges 20, the safety bracket 29 and the pressure plate 31, or, accordingly, can be carried out in a variety of ways, so that here the applicant refuses from a detailed description of these parts. In this case, these features can be borrowed from the description of Fig. 1 - Fig. 9.

The difference between the embodiment shown in FIG. 9 - Fig. 16 in this case lies in making a fixing connection between the closing cover 1 and the stamp. In this case, the locking element 22 on the actuator 19 is no longer oriented outwardly, but is rotated by 90°, so that the orientation of the locking hook 35 runs parallel to the drive surface 21. It is possible that only one locking hook 35 is installed, or two locking hooks 35 and 36, and the design with two locking hooks 35 and 36 turned out to be preferable, since the retention of the closing cover 1 on the stamp 2 is improved.

Both fixing hooks 35 and 36 are fed towards each other, i.e. the protruding elements 37, 38 of the locking hooks 35, 36 are directed towards each other, so that the snapping with one or two locking projections 39 on the stamp 2 occurs in the space 40 formed between both locking hooks 35, 36.

Thus, it can be said that the locking projection 39 of the stamp 2 located on the inner side 41 of the top part 3 is placed in the space 40 between both locking hooks 35, 36, thereby creating a locking connection. In this case, it turned out to be preferable to make the locking protrusion 39 v-shaped, so that when the closing cap 1 is pressed onto the stamp 2 by means of the v-shaped surfaces 42 of the locking protrusion 39, the locking hooks 35, 36 on the actuator 19 of the closing cap 1 are slightly pressed apart until they will not be moved by the locking protrusion 39, and then the protruding elements 37, 38 return to their original position so that the locking protrusion 39 enters the gap 40, as shown, for example, in FIG. 14, i.e., that the protruding elements 35,36 are adjacent to the upper side 43 of the fixing protrusion 39 and fix, respectively, keep the closing cover 1 from falling off the stamp 2.

However, in order for the closing cap 1 to be separated from the stamp 2, it is necessary to actuate said or specified actuators 19 on the closing cap 1 by applying pressure. This is done preferably with two fingers of one hand, so that these actuating elements 19 are compressed, i.e. are shifted towards the center of the closing cover 1. The molded locking hooks 35, 36 located on the actuating elements 19, respectively, are thereby shifted, as schematically shown by arrow 44 in FIG. 15b. In this case, the linear displacement of the locking hooks 35, 36 with the actuator 19 must be carried out until the locking protrusion 39 is removed from the gap 40 between both locking hooks 35, 36, so that the locking cover 1 can be removed downwards, i.e. . from stamp 2.

Thus, again, as in the exemplary embodiments of FIGS. 1 - Fig. 8, the disconnection of the closing cover 1 and the stamp 2 is carried out due to the activation of the actuators 19.

Of course, it is also possible to design in which the locking hooks 35, 36 are not directed towards each other, but they face in the opposite direction, i.e. out. In this case, each locking hook 35, 36 corresponds to its own locking protrusion 39, so that this fixing protrusion 39, after inserting the closing cap 1 onto the stamp 2, is again adjacent to the upper side 43 and thereby prevents the cap 1 from falling off the stamp 2. This kind of option shown in Fig. 16 in a simplified form, with the stamp 2 closed by the closing cover 1, and the locking hooks 35, 36, of which one single locking hook 35 can be used, are directed outward, and the locking hooks are oriented parallel to the drive surface 21 of the actuator 19.

For the sake of order, in conclusion, it should be noted that for a better understanding of the design of the system 1 and its components, respectively, its components, their images in the drawings are presented partially out of scale and/or on an enlarged scale and/or on a reduced scale.
