From the document DE 28 56 854 A1 is known a tape stamp with a solid body handles made of plastic with front and rear walls and two side walls, and held fixed there gripping discs with drums that swirls stamp ribbons with the letters. This one-piece plastic body forms a handle for manipulation of the stamp and fixed accepts there is a separate part of the stamp. On the front wall of the housing and the rear wall of the housing is formed of reeds, between which are one-sided open slot. Additionally, in the area of the stamp is held between the side walls of the transverse crossbar that can sit down on the side walls of the housing. This crossbar entwined stamp ribbons and when burned is to support them. Due to this crossbar get a guide surface for a sliding stamp tapes in interaction with the whole body of the handle.

From the document DE 203 09 613 U1 known calendar stamp, comprising a housing with bracket, frame stamp and protective coating, which has a U-shaped cross-section. At the same time frame stamp is located in the attachment of a body can move, and in the building there is a swab to paint. The frame stamp has several installation disc is in, and some ink ribbons, which are respectively provided with otyskivali surface of letters, numbers, and/or symbolic images. For mutual connection of the protective cover with frame and stamps, on the one hand, the frame stamp has two screws on the bottom part of the clamping part, and, on the other hand, the protective coating has two defined on two sides of the retainer. Holders of protective coating formed in its end walls. This fixation of the protective coating on the frame stamp is due to the expansion of the U-shaped jaws almost in a perpendicular direction with respect to the axis of the installation disks. During this deformation process of the clutch occurs mainly in the arcuate region of the U-shaped cross-section of the protective coating. In all cases it was impossible to achieve reliable fastening of the protective coating on the frame of the stamp.

From the document WO 2006/079129 A1 became known hand-stamp, in particular samoobrazovanie stamp containing the drive bracket and the body of the stamp with a transfer mechanism for a literal set. The set of characters can move through the drive bracket and roll over at 180 from the upper position of rest at the bottom, inverted position printing. A set of characters contains the number of installation of the sprockets, and also lettered tape. Further, the covering is provided in the form of a casing for the lettered tape, which has slits for hanging out of the circle of the installation asterisks. Between the coating in the form of a casing and a support part of a literal set is hitch for mutual engagement. On both shelves supporting part on the outside, opposite the lettered tape side it has two protruding radially outward suzanah ledge that interact with protruding spikes on the end cover in the coupled position. The process of coupling between the coupling elements occurs in radial and respectively perpendicular direction with respect to passing through the installation of asterisk longitudinal axis. Reliable fixing of the coating in the form of a casing in the direction of the axis of rotation of the installation of the stars could not be achieved in all application cases.

From the document AT 000 379 U1 became known protective sheet coating in the form of a U-shaped metal or plastic housing, which is provided by the openings for the through-ledge installation of wheels and sheet coating that covers located on the bushings installation of wheels lettered tape. For fastening and fixing sheet covering the nozzle body is held between the side when the parties of the front and rear cross members, who on their part have openings for receiving the inserted over the lettered tape sheet coating. Because of this, you can push provided in the nozzle body, the slits the sheet covering it slots above the alignment stars so far, while the cover sheet will not hold the clamp in nozzle housing. In all practical cases, however, it was impossible to achieve reliable and durable attachment between the cover sheet and the nozzle body.

Other hand dies with the body of the stamp, which still are lettered tape with the United with them the adjusting wheels are known from the document DE 2156157 A and CH 258021 A.

The basis of the present invention have the task to create a supplementary element for stamps, which can be achieved accurately positioned and reliable fastening of the protective element of the cover on the housing of the Packed item.

This object of the invention is solved by the fact that between the end part of the protective element and the side part of the nozzle body is located a guiding device. The resulting according to characteristics of the characterizing portion of paragraph 1 of the claims advantage is that, on the one hand, guiding device facilitates the connection process and, accordingly, nasaji the project for a protective element on the nozzle body, and on the other hand, you can achieve additional positioning relative to the longitudinal axis on the axis of installation of wheels. As a consequence, achieve not only the mutual prior alignment between the joined parts, and appropriate positioning. In addition, it is possible to achieve precise centering and bearing between the protective member and the nozzle body. At the same time, however, due to this unintentionally transferred to the protective element forces during regulation separate installation of the wheels can be transported due to this protective element on the nozzle body. Further, due to a favorite relative movement direction when the coupling of the interacting elements of the clutch in the perpendicular direction to the U-shape is made from a cross-section of the protective element creates a more reliable connection, as well as the exact mutual positioning between the bond details. It is independent of the relative location and position of shelf protective element against the nozzle housing. The mutual alignment of the protective element relative to the nozzle housing also plays a significant role in the interaction of installation of wheels with these respective slits in the protective element. If the protective element UD is rivets appropriately positioned in the axis direction, the gap between the slot and the corresponding installation wheel can be considered as insignificant without that happened mutual contact and, accordingly, the mashing. Similarly, weakening the preliminary voltage of the protection element is made U-shaped, also plays no role for the applied clamping force. Inadvertent separation of the parts when the permutation and, accordingly, the shift shelves protective element does not therefore to any unintentional disengagement of the coupling device, as this may occur, for example, during manipulation of the adjusting wheels. This is because the direction of motion for the transmission when the clutch elected rotated approximately 90 with respect to the force of the pressure applied during the rotary movement of the adjusting wheel.

The following form of execution under paragraph 2 of the formula of the invention is also advantageous because as a result simple means can be created easily produce a coupling element, which makes possible a reliable, stable and long-term attachment.

Hereinafter, an embodiment according to paragraph 3 of the formula of the invention is preferred, as this ensures a reliable interaction with the coupling element formed with a receiving hole.

By running under paragraph 4 or 5 of the claims, it is possible to facilitate the separation being in engagement with each other of the clutch elements for conscious removing the protective element with the nozzle housing. However, it is now necessary to withdraw the lug from engagement with the receiving hole from the outside using a suitable tool, respectively, and then the protective element can simply be removed.

By another variant of execution, pursuant to paragraph 6 or 7 of the claims, is created just received the coupling element, which ensures reliable and durable fastening of the protective element on the nozzle body.

It is useful as an advanced option, according to paragraph 8 of the claims, as this results in the cover element coupling with the external side of the protective element.

Through the implementation of paragraph 9 of the claims are possible and exact positioning of the place in the field axis to facilitate additional leveling movement of the protective element relative to the carrier Board and, accordingly, the bracket body.

When performing according to claim 10 of the formula of the invention is preferred, due to it is created directed from the outside towards the center of the nozzle body towards the giving movement when the clutch and as a result are not familiar with this area of technology users is difficult and, accordingly, prevents the separation of the protective element with the nozzle body.

Through the improvement according to claim 11 claims reach that this creates a contact surface oriented perpendicular to the direction of connection concatenate each other parts, namely the protection element and the nozzle body, which prevent mutual separation of the clutch elements.

When executing under section 12 or 13 of the claims, for the process of the clutch may be engaged inherent in the material elastic properties, and then the main body of the protective element can be performed with higher own rigidity.

Through improvements, according to 14 of the claims reach that thus attainable is also a certain floor spaced from the side edges of the installation of the wheels and still is possible to perfect the process of coupling forming coupling elements.

In the variants perform according PP-18 claims, it is preferred that thus, through one or more connecting jumpers, achievable additional coupling separate h the values of the walls of the protective element, and it is also achievable even directional transmission and the associated higher rigidity being with each other in the engagement of the elements of the coupling device. It is additionally strengthened by the arrangement of the connective jumper, when considering in the direction of the axis, in the upper section and, respectively, in the apex region is made U-shaped in cross-section of the protective element. Thus, due to this connection, the width of the slots in this field is kept constant and avoid rubbing and, accordingly, clamping installation of the wheels during installation.

By performing according to claim 19 or 20 claims it can prevent the inward ends of the shelves protective element towards the lettered tape. Because of this not only facilitates the installation, but also avoid damage and possible mutual distortions and together with the increased effort to reinstall.

Finally, the next best option perform specified in paragraphs 21 and 22 of the claims, and it should be borne in mind achievable benefits description.

First you need to install that described different forms of execution of the same parts are supplied with the same reference positions and, accordingly, the same element names, and are contained in the General description about the differences can be transported in meaning to the same parts with the same reference positions and, accordingly, the same element names. Also selected in the description guidance on the location, as for example, at the top, bottom, side etc. belong to the directly described and presented to the drawing, and by changing the position they need to carry meaning to the new location. In a further separate PR the signs or combinations of signs of the shown and described various examples can also be a separate, containing the novelty or corresponding to the invention the solution.

Figure 1-3 shows possible and in a case of self-embodiment of stamps, in particular, the nozzle element 1 with the nozzle body 2 for stamps, which is made, for example, in the form of a date stamp and can be individually regulated by the appropriate date, and, accordingly, other font characters and graphic symbols. Here, for simplicity, it seems only common nozzle element 1 to the stamp, with the following details for the formation of stamps, such as the case of stamps, as well as independent paint graphic symbols, etc. to the invention here do not apply.

Nozzle element 1 in the example presented here, run formed the base plate 3, a bracket 4 of the housing with the side parts 5, 6 and the axis 7. The carrier Board 3 has at its center a through opening for part of the stamp, so that, on the one hand, to guarantee flawless support provided for applying a stamp surface and, on the other hand, also be additional graphic symbols and, respectively, to accommodate them.

Further, to the nozzle body 2 is attached a set of 8 installation of wheels with multiple installation toothed wheels 9, which are mounted in bearings with the possibility of rotation system-easy installation the I around the axis 7. When this setting wheel 9 serve to maintain the lettered tape 10, and the adjusting wheel 9 at its outer perimeter to form the circumference 11 of your wheels. To cover lettered tape 10 at least in the field of set of 8 installation of the wheels has a security element 12, and he has provided next, depending on the individual installation of the wheels 9, the slots 13 for the passage of at least circles 11 installation of the wheels 9. While the protective element 12 has a main body 14, with respect to the axis 7 is formed U-shaped in cross section. Due to the fact that the installation of the circumference 11 pass through the slots 13 and the main body 14 of the protective element 12 covers located between the adjusting wheels lettered tape 10, for a user of such a nozzle element 1 upon actuation of the installation of the wheels 9 preventing contamination of the fingers are used, and, accordingly, bear the typographical characters from adhering to them stamp ink.

Lettered tape 10 depending located on them relative to each other graphic symbols and, respectively, stamp characters can have different widths in the direction of the axis 7. In the area of the base plate 3 lettered tape 10 is attached is not described in detail here aiming the I surface, which is the plane of the centers located on the lettered tape 10 graphic symbols relative to the plane of the stamp and, accordingly, its top surface. Consequently, in a known manner to reach the installation complete contact and associated with this impeccable result of die stamping and woodblock.

For fastening and, accordingly, the adhesion of the protective element 12 with the nozzle body 2 between them there is at least one coupling device 15. This coupling device 15 for its part, has, respectively, interactive elements 16, 17 of the clutch on the nozzle body 2 or, respectively, on one of its component parts, as well as on the protective element 12. While interacting elements 16, 17 of the clutch are made so that when the clutch relative to the direction of movement of the elements 16, 17 of the clutch to each other are oriented approximately in the direction of the axis 7 of the nozzle body 2. This means, in relation to the execution of the main body 14 of the protective element 12 in a U-shape, the direction of motion when the clutch is oriented approximately perpendicular direction relative to the cross-section, is made U-shaped. Due oriented approximately in the direction of the axis 7 in the direction of movement when the clutch can be prevented from unintentional separation sasanov the element 12 during the installation process on the circumferences 11 installation of the wheels 9.

By double arrows in Fig. 2 shows the direction of movement when the clutch interacting elements 16, 17 of the clutch, and for the process of coupling first need to move the elements 17 of the coupling parts 24, 25 of the side wall facing to the installation wheels 9 direction, i.e. inside. With proper alignment and positioning relative to each other, the clutch element 17 of the protective element 12 may then be brought into engagement with the first clutch element 16 in the area of the lateral sides 4, 5. However, during the connection process can happen elastic deformation of the side parts 5, 6 of the nozzle body.

Best coupling device 15 can be seen from comparative overview Fig. 2 and 3. Here the first clutch element 16 is formed of the receiving hole 18 in the region of the side parts 5, 6 of the nozzle body 2. Thus the lateral part 5, 6 can be element of the carrier Board 3 and/or bracket 4 case.

The protective element 12 is previously described, is made U-shaped in cross section main body 14 and spaced from each other in the direction of the axis 7 of the end region 19, 20. In the area of these end regions 19, 20 on the protective element 12 is one or more elements 17 of the clutch, which is formed in this case in the form of a protrusion 21. This is done in the form of a protrusion 21 item 17 of the clutch after the corresponding relative displacement, and accordingly, displacement of the cover element 12 in a perpendicular direction to the axis 7 drops into the clutch element 16, made in the form of the inlet opening 18. In this case, another clutch element 17 acts in the direction opposite to the installation of the wheels 9 side. Thus the first element 16 of the clutch in relation to the next element 17 of the clutch is located on the opposite mounting wheels 9 side and thus they are farthest away from each other. Preferably both of the side parts 5, 6 of the nozzle body 2, and addressed to him the end regions 19, 20 of the protective element 12, respectively, is provided for coupling 15 with the forming elements 16, 17 of the clutch. Further, the axis 7 is preferably held between the side parts 5, 6 of the nozzle body 2 and serves to support the installation of the wheels 9.

The first clutch element 16 with its receiving hole 18 is made here about the form of the bracket and has turned to the connecting block of the protective element 12 side is preferably a flat surface 22 of the seal, which in the coupled position interacts with a formed on the protrusion 21 of the other surface 23 of the seal and thus prevents inadvertent removal of the protective element 12 with the nozzle body 2. For easier connection to the speaker is 21 when considering in the direction of the clutch or accordingly, a connection is made beveled stabilizer to facilitate the process so the connection or, respectively, of the clutch. Axis 7 both surfaces 22, 23 of the seal is oriented in parallel with it. Preferably the surfaces 22, 23 of the fit are also in parallel are not presented here in detail printed surface for applying printed.

The protective element 12 in addition to the main body 14 has at its both end regions 19, 20, respectively, at least partially closing the end parts 24, 25. At these end portions 24, 25 is preferably another clutch element 17 or, respectively, the protrusion 21. To facilitate movement when the connection end portion 24, 25 elastically connected with the main body 14 of the protective element 12.

Taking place in the direction of the axis 7 relative movement of the coupling between the elements 16, 17 of the coupling can be carried out during the process of coupling by a corresponding shift of the side parts 5, 6 and/or end parts 24, 25. This movement of the shift can be realized simply and confidently when made of plastic, for example by way of injection molding, the parts at the expense inherent in the material elastic properties. Exactly the same can be provided, however, weakening of the material is set on the s sites which form something like a hinge, however, in the coupled position of the side parts 5, 6 and/or end parts 24, 25 are of sufficient strength and, accordingly, the stability in maintaining their relative position to interacting elements 16, 17 of the clutch.

Further, it is advantageous, if between the end portion 24, 25 of the protective element 12 and the side part 5, 6 of the nozzle body 2 is provided at least one guiding device 26. This guiding device 26 serves to, on the one hand, to facilitate the connection process and, accordingly, putting a protective element 12 on the nozzle body 2 and, on the other hand, to reach the position on the axis of the installation of the wheels relative to the longitudinal axis. As a consequence, achieve not only the prior mutual alignment between the joined parts, and appropriate positioning of their provisions. In addition, you can also get accurate guide surface and a support between the protective element 12 and nozzle body 2. At the same time, however, during the process of making individual adjustments to the installation of the wheels 9 as a consequence, can be removed unintentionally transferred to the protective element 12 forces from the protective element 12 on the nozzle body 2. Using the corresponding interacting on rawsumer parts guide device 26 may further limit movement of the coupling between the protective element 12 and nozzle body 2, in particular bracket 4 case.

However, regardless of this, it is also possible to arrange the above-described elements 16, 17 of the coupling mirror-inverted relative to each other on the protective element 12 or, respectively, on the side parts 5, 6. Thus the receiving hole 18 would be located or, respectively, formed in the side walls 24, 25 and the ledge 21 on the side parts 5, 6.

Figure 4-6 shows another and in a case of self-embodiment of a nozzle element 1, and again for the same parts the same reference numbers and, respectively, the names of the elements, as in the previous drawings figure 1-3. To avoid unnecessary repetitions, given instructions and, accordingly, references to the preceding detailed description figure 1-3.

Presented here figs.4-6 hitch 15 is between the protective element 12 and nozzle body 2 interacting elements 16, 17 of the clutch, and here, in contrast to the previously shown in figure 1-3 coupling device 15, the first clutch element 16 is made in the form of the inlet opening 27 in the axis 7. Preferably the receiving hole 27 made in the axis 7 of the cylindrical. While the other clutch element 17 is made in the form of a cylindrical ledge protruding in the direction of installation of wheels . Thus in the position of the clutch it engages the outside in the direction of the axis 7 formed in there receiving hole 27.

On the side parts 5, 6 are made of the support surface 30 provided on the one hand, to the support axle 7 is made approximately semicircular form the seats 28 and, on the other hand, for a bearing supporting part 29 of the protective element 12. Supporting part 29 serves here as an intermediate element between the end portion 24, 25 and is made in the form of a trunnion element 17 of the clutch coupling device 15.

By double arrows on figure 5 presents the direction of movement of the clutch interacting elements 16, 17 of the clutch, and to process the first clutch elements 17 clutch with bearing part 29 and, accordingly, the end portion 24, 25 to move in the opposite mounting wheels 9 direction, i.e. outwards. Only with proper alignment and positioning relative to each other, the clutch element 17 of the protective element 12 is brought into engagement with the first clutch element 16 in the area of the axis 7. This elastic displacement for the process of coupling can occur here also due to the inherent material properties of parts, particularly when they are made by a method of injection molding of plastics. However, it would also be possible and other materials, as for example, metal material or fiber reinforced plastic, and you should always pay attention to the relative direction of movement of the clutch elements 16, 17 clutch happened to each other about the axis 7 of the nozzle body 2 about its direction.

In all of these embodiments described above perform is always provided by the Central location of the interacting elements 16, 17 of the clutch. This occurs mainly in the region of the axis 7 and, respectively, the plane passing centrally to made U-shaped shelves of the main body 14. Another bearing protective element 12 in coupled condition occurs also on the carrier Board 3, resulting so-called bearing on three points for the protective element 12 on the nozzle body 2. While the previously described elements 16, 17 of the clutch can interact in the form of a snap connection, and it also may occur alignment when viewed in the direction of the axis 7.

The examples show possible embodiments of the nozzle element 1, in particular its coupling 15 between the protective element 12 and nozzle body 2, and here it should be noted that the invention is not limited specifically represented by the variants of its implementation, and opposite t is the train various combinations of the individual embodiments between them, and this alternative is allowed changes - due to knowledge of technical actions using the present invention depends on the skill of the acting in this technical area specialist. Thus all possible variants of implementation, which is possible due to the combinations of the individual parts are listed and described scenarios covered by the protected scope of the invention.

7 to 10 shows another in certain cases, a separate embodiment of a nozzle element 1 with the nozzle body 2 for stamps, and again for the same parts the same reference numbers and, respectively, the names of the elements, as in the previous figure 1-6. To avoid unnecessary repetitions, given instructions and, accordingly, references to the preceding detailed description figure 1-6.

Shown here, the coupling 15 between the protective element 12 and nozzle body 2 has the same effect as the coupling device 15, which has already been described in detail using Fig 1-3. The coupling device 15 also has, in this case respectively interacting elements 16, 17 of the clutch on the nozzle body 2 or, respectively, on one of its component parts, as well as on the protective element 12. While interacting the coupling elements 16, 17 again performed so that the relative direction of movement of the clutch elements 16, 17 clutch is oriented to each other, approximately in the direction of the axis 7 of the nozzle body 2. This means, on the implementation of the main body 14 of the protective element 12 in a U-shape, the direction of movement of the clutch is oriented approximately perpendicular direction relative to the cross-section, is made U-shaped.

In the previously described figures 1-6 the form of the protective element 12 slot 13 for receiving the adjusting wheel 9 ends, respectively, before reaching the ends of the shelves of the main body 14 and is limited there made jumper detail, which, for its part, in the form of execution according to Fig 1-6 fixed on the base plate 3.

The protective element 12 in this and the previously described forms of execution formed a separate polusobrannye parts 31 of the walls, between which are formed the slots 13. These side walls 31 are connected to each other in the General detail of the locking strap in each end region of the shelves of the main body 14. To improve the stability of parts of the walls 31 and/or coupling device 15 of the protective element 12 at least in the upper region and, accordingly, on the site of its peaks in the transition region between the shelves of a U-shaped part has at least one additional jumper 32. This connective jumper 32 is held in parallel voltage is the t to the axis 7 between the spaced apart end regions 19, 20, associated with parts of the walls 31 and preferably be continuous. This direction may be referred to as perpendicular to the cross section of the protective element 12. In this example, run a jumper 32 is connected here not only with the portions 31 of the walls, but with the parts 24, 25 of the side walls of the bearing and, accordingly, the principal elements 17 of the clutch. However, the invention can be seen also to create a protective element 12, which, in particular, in the field of individual, separated from each other by slits 13 parts 31 of the walls has a higher strength and, accordingly, the rigidity. This can take a higher load all of the protective element 12. These loads on the protective element 12 can be determined by the design and principle of operation of the coupling device 15, and also occur during mounting on the nozzle body and, consequently, also during adjustment separate installation of the wheels 9 on it. While this task should be considered regardless of the design of the coupling 15. While many possible options for the location of the connective jumper over 32 through the slot 13 when seen in a cross section of the protective element 12.

Connecting the jumper 32 is held at selected, the greater distance in the radial direction, R is smotriny relative to the installation of the wheels 9, between the end regions 19, 20 and, respectively, the end portions 24, 25 in such a way that, on the one hand, it is possible the smooth installation of the wheels 9 and related reinstalling and, on the other hand, creates a stable coupling of the individual parts 31 of the walls in the opposite axis 7 field installation of the wheels 9. When this circle 11 installation of the wheels 9 is overlapped with the observance of the radial distance from the jumper 32. It is used for contactless separate installation of the wheels 9 in the area of inter-connector 32. This connective jumper 32 can also be made U-shaped, when seen in cross-section, i.e. in its longitudinal direction and, respectively, in the direction of the axis 7, as is best seen in figure 10. While connecting the jumper 32 is made rising regarding the external surface of the individual parts of the walls 31 and protrudes above the surface opposite to the axis 7 of the hand, or direction. As a result, along with a stable coupling device 15, is still high stability of the protective element 12 at the site of its vertices. Due to this, it is possible to manage with a smaller wall thickness and still achieve sufficient strength for the protective element 12, and executed thereon coupling the disorder 15.

Connecting the jumper 32 located on it here and, accordingly, the related end parts 24, 25 also forms a U-shaped or C-shaped arrangement, which, however, relatively U-shaped protective element 12 is offset at 90 to it. When the two U-shaped parts of the shelf and, accordingly, the end parts 24, 25 are in the same direction.

The end parts 24, 25 are again previously described elements 17 of the clutch and at the same time also form a guiding device 26 for alignment relative to the bracket 4 of the housing.

With this additional connection crosspieces 32 possible deformation of the parts 24, 25 of the side walls, when considering in the direction of the axis 7, to enter the coupling elements 16 and 17 respectively in engagement with each other and, respectively, output from it. For this purpose between the end parts 24, 25 and directly adjacent parts of the walls 31 formed by the gap, which in its width to the light may correspond to, for example, the width of the slot 13 for the reception of the corresponding installation of the wheel 9, or may be formed also slightly larger. It depends on the location and design elements of the clutch 16 on the bracket 4 of the housing and, accordingly, the lateral parts 5, 6. If you select multiple broader and matched with the public, gap, the process of coupling between the two interacting elements 16, 17 of the clutch can be performed more simply. However, in this area due to the location of the connecting crosspieces 32 yet achieved sufficient strength only protective element 12, in particular its coupling device 15.

Here, in contrast to the previously described forms of execution of the protective element 12 is offset from and, respectively, the deviation of the parts 24, 25 of the side walls around centrally located on the hilltop site of the protective element 12 of the turning area due to the simultaneous rejection of both end parts 24, 25. However, when the previously described figure 1-6 forms of execution, parts 24, 25 of the side walls rejected around the rotary area, located in the region of the ends of the shelves. Consequently, during the clutch is eccentric offset and, accordingly, the deviation of the end parts 24, 25 relative to the plane of symmetry of the cross-section of the protective element 12, made U-shaped, and, accordingly, the parts 31 of its walls.

Opposite the connecting crosspiece 32 the ends of the parts 31 of the walls in the area of the ends of shelves U-shaped protective element 12 may be again connected to each other in a single piece. Because of this again improves the stability of individual parts thenac, in particular, against deformation in this area. The ends of the shelves of the protective element 12 in the area of parts 31 of the walls of the slide in the base plate 3 within jumpers 33 inside her. Due to this, avoid inadvertent retraction of shelves U-shaped protective element 12 in this area. However, additional potential corresponding bearing and the associated stabilization of the protective element 12 relative to the base plate 3.

For mounting the protective element 12 on the bracket 4 of the housing may nadivana protective element 12 on the installation of the wheel 9 due to the elastic sliding shelves protective element 12. This movement overlap occurs as long as the elements 16, 17 of the clutch coupling device 15 will not be in engagement with each other. This movement of the cover is facilitated by the previously described guide device 26 in the area of the parts 24, 25 of the side walls and the bracket 4 of the housing. Also in the field directing device 26 may be a limit stop for movement of overlap, which best can be seen in Fig.7. The components of and, respectively, jumper guide device 26, which are located in the area of the end parts 24, 25, encounter interacting with them supporting surface and, accordingly, reference edges on the bracket 4 of the housing and, accordingly, its lateral parts 5, 6

On 11-13 shows another in certain cases independent form of the nozzle element 1 with the nozzle body 2 for stamps, and again for the same parts the same reference position and, respectively, the names of the elements, as in the previous figure 1-10. To avoid unnecessary repetitions, given instructions and, accordingly, references to the preceding detailed description figure 1-10.

Shown here, the coupling 15 between the protective element 12 and nozzle body 2 has the same effect as the coupling device 15, which has already been described in detail using Fig 1-3 and, respectively, 7-10. So this in more detail will not be returned.

The protective element 12 at its spaced from each other in the direction of the axis 7 of the end regions 19, 20 forms the ends 34, 35 or, respectively, the end surface, which are directed to one another supporting elements 36. These supporting elements 36 are used for the protective element 12 in the fully assembled position on the bracket 4 corps was based in provided for the reference region 37. Thus attain assistance during installation, which facilitates Assembly of the unit from the bracket 4 buildings, set of 8 installation of wheels and a protective element 12 with the base plate 3. In addition, still other prob is tenderly, to the supporting elements 36 rested, looking in the direction of the ceiling, and even on the carrier Board 3 or, respectively, its parts and, thus, provided for the protective element 12 additional restriction of the movement of overlap relative to the base plate 3. You can not only avoid the elastic compression of the protection element is made U-shaped, in particular, parts 31 of its walls, but also to achieve precise positioning of the protective element 12 relative to the base plate 3, and a set of 8 installation of the wheels.

By means of the guide device 26 of the protective element 12 also on its hilltop site accurately positioned in its position in relation to the set of 8 installation of the wheels and the base plate 3. Because this is made possible trouble-free reinstallation separate lettered tape 10 installation wheels 9.
