AI Technical Summary
Existing pocket stamps require manual translational movement followed by pivoting of components to transition from a closed to an operating position, which can lead to operational inefficiencies and increased risk of collision during opening and closing.
A pocket stamp design where the transition from a closed to an operating position is facilitated by the restoring force of a clamping element, synchronizing the movements of the plate and cushion carriers through a mechanism involving a locking mechanism and a clamping element, such as a tension-compression spring, which is preloaded during assembly to drive the movement without manual force.
The design ensures reliable, reproducible operation with reduced component wear and improved user safety by decoupling manual effort from the opening mechanism, allowing one-handed operation and synchronized movement of components.

Abstract
Description
[0001] Taschen's temple
[0002] The invention relates to a pocket stamp comprising at least a housing, a cushion carrier, a plate carrier and a clamping element, wherein a transition of the pocket stamp from a closed position to an operating position is accompanied by a movement of the plate carrier and a movement of the cushion carrier and is effected by the restoring force of the clamping element, as well as a method for assembling a corresponding pocket stamp and a method for commissioning a corresponding pocket stamp.
[0003] To make stamps and stamping devices easier to transport, and in particular to protect the ink pad and text plate from unwanted contact, it is known to construct pocket stamps in such a way that they can be moved from a closed position to an operating position. It is known to mount a pad holder, in which an ink pad is usually stored, and a plate holder, on whose imprinting surface a text plate is usually attached, in a pivotal manner, so that the imprinting surface of the plate holder is covered by the pad holder in the closed position and the text plate is in contact with the ink pad. Moving the pocket stamp into the operating position usually requires an initial (and manually induced) translational movement of the plate holder and the pad holder, or at least of the plate holder, relative to the housing.Following this, or partially overlapping with the translation, at least the plate carrier is pivoted so that the text plate of the plate carrier is exposed and oriented towards a printing surface. If the cushion carrier is also pivoted, this pivoting usually occurs at different times and in opposite directions of rotation to avoid collisions during opening and closing.
[0004] EP 4 303 025 discloses such a pocket punch, comprising a housing and a slide, wherein the transfer of the pocket punch from the closed position to the operating position is accompanied by a manually actuated movement of the slide. For this purpose, the slide is movably mounted along the housing, preferably along the longitudinal extension of an elongated housing, and mechanically coupled to the movement, in particular the pivoting, of the plate carrier and the cushion carrier. The movement of the slide is manually actuated by an external slide guided outside the housing and engaged with the slide. The plate carrier is rotatably mounted on the slide and provides a further, eccentrically located pivot point with the fixed pivot point of the slide, movable engagement point at which the housing engages.The relative movement between the pivot point and the point of attack during the movement of the slide causes the plate carrier to rotate relative to the slide.
[0005] The ink pad carrier of the pocket stamp according to AT 520 700 Al alternatively has a pivot point fixed to the housing and is rotated by the relative movement between the fixed pivot point and an engagement point fixed to the slide. The pivot point of the plate carrier is fixed to the slide; a second engagement point is provided by the pivot point of a second slide movable relative to the first slide. The pocket stamp shown also has a transfer mechanism that is pre-tensioned in the closed position; that is, clamping elements, in particular torsion springs, are provided with the aid of which the transfer of the pocket stamp from the closed position to the operating position is facilitated. The clamping element cannot cause the slide to advance along the housing in the closed position of the pocket stamp, i.e., when the impression surface of the plate carrier and the ink pad of the ink pad carrier are facing each other.Therefore, despite the clamping element, the first partial movement of the transition from closed to operating position must be effected by an initial (manually induced on an external slide) translational movement of the slide, plate and cushion carrier.
[0006] In detail, the pocket stamp according to AT 520 700 Al features a torsion spring engaged with the slide and the ink pad carrier. The torsion spring acts around the pivot point of the ink pad carrier, which is fixed to the slide. As soon as the initial translational movement of the slide releases a fulcrum point of the ink pad carrier, i.e., as soon as a wall of the housing no longer restricts the pivoting of the ink pad carrier, the restoring torque of the torsion spring causes the ink pad carrier to pivot and drives the coupled translation of the slide up to its maximum displacement amplitude. The plate carrier, which is rotatably mounted on the slide, is rotated, as described above, by a second slide that acts eccentrically with respect to the pivot point of the plate carrier and is also coupled to the ink pad carrier, until its impression surface faces a pressure surface.
[0007] A known embodiment also includes torsion springs acting around both the pivot point of the cushion carrier and the pivot point of the plate carrier, both fixed to the slide, and the pivoting of the cushion carrier and the plate carrier is effected by their restoring torque. As with the pocket die of the AT 520 700 Al, after an initial translational movement of the slide, the respective lever points are gradually released, i.e., after an initial (and manually induced on an external slide) translational movement of the slide, plate and cushion carriers.
[0008] CN 204160915 U of fenbart describes a pocket stamp which has only a torsion spring acting around the axis of rotation of the plate carrier. In this design, the cushion carrier is not pivoted, but moved translationally into the housing of the pocket stamp, so that the plate carrier is given sufficient space to pivot after only a short translational movement.
[0009] AT 505992 All of fenbart comprises a pocket stamp comprising a first housing part into which a stamp plate is inserted, and a second housing part which carries an ink pad, as well as a pre-tensioned torsion spring which pivots the second housing part relative to the first housing part after the pressure elements on the housing part are actuated, thus moving the pocket stamp into an open position. The housing part serves as the handle of the pocket stamp. During the movement into the open position, the stamp plate is pushed out of the first housing part in the direction of stamping by a pre-tensioned spring arm mounted in the first housing part, so that the stamp plate protrudes from the first housing part. The movement of the ink pad carrier and the movement of the stamp plate are therefore each driven by a different spring element, so that the pocket stamp requires two spring elements.
[0010] EP 2203316 Bl of fenbart describes a writing instrument with a sleeve and a detachable end piece to which a stamping mechanism is attached. The stamping mechanism comprises a stamp holder to which a stamp plate and an ink pad holder are pivotably mounted. When the detachable end piece is pulled out, the ink pad holder is pivoted relative to the stamp holder by a spring, thereby releasing the stamp plate. The stamp plate is weighted on one side so that its weight rotates it into an impression position. Therefore, the rotation of the stamp plate into an operating position can only be reliably achieved when the stamp holder is in a vertical position.In known, pre-tensioned pocket plungers, the restoring torque of the torsional spring can only generate the advance of the slide along the longitudinal contour of the housing after at least one lever point of the cushion carrier is released by the housing and the orientation of the cushion carrier can deviate from that normal to the advance direction of the slide. Therefore, during the transition of the pocket plunger from the closed position to the operating position, an initial, manually induced movement in the advance direction is required (e.g., by an external slide).
[0011] It is therefore an object of the invention to create a pocket stamp that has improved operating characteristics compared to the prior art and remains inexpensive to manufacture. This object is achieved by a pocket stamp comprising at least a housing, a plate carrier with an impression surface for attaching a text plate, a pad carrier for receiving a stamp pad, and a clamping element, wherein the transfer of the pocket stamp from a closed position to an operating position is accompanied by a movement of the plate carrier and a movement of the pad carrier and is effected by the restoring force of the clamping element.
[0012] Preferably, the closed position is characterized by the imprinting surface of the plate carrier facing the ink pad side of the ink pad carrier. Preferably, the ink pad and text plate are in contact in the closed position. Preferably, the movement of the plate carrier and / or the movement of the ink pad carrier is a pivoting motion, particularly preferably a rotation. The axis of rotation of the pivoting motion is preferably fixed to the housing, particularly preferably parallel to the orientation of a first side of the housing. Preferably, the axis of rotation of the plate carrier and / or the ink pad carrier is a pin-and-hole connection, wherein the holes are formed on the plate carrier and / or the ink pad carrier and the bearing pins are formed on the housing, or vice versa. Preferably, the axis of rotation of the plate carrier is parallel to that of the ink pad carrier. Preferably, the imprinting surface of the plate carrier faces the printing surface to be printed in the operating position.It is particularly preferred if the start of the pivoting of the plate carrier is delayed in time compared to the start of the pivoting of the cushion carrier. It is also particularly preferred if the direction of rotation of the plate carrier is opposite to that of the cushion carrier. Preferably, the external appearance of the pocket punch in the closed position is defined by the housing, the plate carrier, and the cushion carrier. Preferably, in the closed position, a second outer surface of the cushion carrier and a second outer surface of the plate carrier of the pocket punch are aligned with one of the second sides of the housing. Preferably, in the closed position, the housing is flush with the cushion carrier and / or the plate carrier. Preferably, in the closed position, the plate carrier and cushion carrier are also flush with each other.Preferably, a second outer surface of the cushion carrier and a second outer surface of the plate carrier are arranged at an angle to a second side of the housing in the operating position of the pocket punch; particularly preferably at an angle of 30–90° and 90–115°, respectively. It is also advantageous if a first engagement point of the clamping element is fixed to the housing. The housing preferably comprises locking components, bearing recesses and / or bearing pins for the cushion and / or plate carrier, at least one release, a receiving device for the clamping element, a guide rail for the slide, and / or catch tabs. The housing is preferably designed in two parts. Preferably, and particularly preferably, the housing is provided by a first and a second housing part. The first housing part preferably has at least one locking component and / or a catch tab.Preferably, the housing parts of the pocket punch are firmly connected to one another in the assembled state. Preferably, the housing, in particular the first housing part and / or the second housing part, is made of POM. This preferred material choice results not only in elastic behavior but also in good sliding and strength properties, which counteract wear and breakage at friction surfaces (e.g., bearing recesses). The clamping element generally functions as a drive element for moving the pocket punch from the closed position to the operating position. In particular, it can drive the entire movement sequence, starting with the (possibly unlocked) closed position, preferably up to the operating position. By having this movement sequence initiated or driven by the clamping element or drive element, high reproducibility of the acting forces and ultimately high reliability of the pocket punch can be achieved.In particular, incorrect operation of the opening mechanism, such as the application of excessive force, can be avoided. Preferably, the opening and unfolding of the plate carrier is mechanically decoupled from the user's operation. The user can open the pocket punch without ever exerting force on the slide. For reliable commissioning and / or a reduced number of components in the pocket punch, it is advantageous if both the movement of the plate carrier and the movement of the cushion carrier during the transfer of the pocket punch from the closed position to the operating position are driven by the restoring force of the clamping element. This means that the movement of the plate carrier and the movement of the cushion carrier can be driven by the same clamping element.
[0013] In a preferred embodiment of the pocket punch, the movement of the plate carrier and the movement of the cushion carrier can be mechanically coupled. This allows the movement of the plate carrier and the movement of the cushion carrier to be synchronized during the transfer of the pocket punch from a closed position to an operating position and / or during the return of the pocket punch from the operating position to the closed position.
[0014] With regard to the pocket punch, it is also advantageous if the restoring force of the clamping element in the closed position of the pocket punch is maintained by a locking mechanism. Preferably, the restoring force of the clamping element reaches a maximum in the closed position. Preferably, the restoring force of the clamping element reaches a minimum in the operating position. The locking mechanism preferably comprises several locking components. Preferably, the locking mechanism has locking components on two, preferably exactly two, of the pocket punch elements, i.e., housings, in particular a first and / or second housing part, slides, clamping elements, cushion carriers, and plate carriers. The locking components are preferably connected to each pocket punch element or formed as part of a pocket punch element.Preferably, at least two, and particularly preferably exactly four, locking components are each designed symmetrically with respect to a plane of symmetry perpendicular to the axis of rotation of the plate carrier. Preferably, the axis of rotation of the plate carrier, and especially also of the cushion carrier, is fixed to the housing. Preferably, the locking components (or corresponding pairs of locking components) are in contact with each other in the closed position. Particularly preferably, at least two locking components, which are formed on different pocket punch elements, are engaged with each other in the closed position. Preferably, the engagement of the locking components of at least two pocket punch elements is positive-locking, particularly preferably by displacement of one locking component relative to another, and / or friction-locking, particularly preferably by one locking component snapping into place relative to another.Insofar as the engagement of the locking components is characterized by a displacement of one locking component relative to the other, this displacement can be characterized along the orientation of a third side and / or along the orientation of a second side and / or along the orientation of one side of the housing. Insofar as the engagement of the locking components is characterized by a snap-fit between the locking components (or, for example, pairs of locking components belonging together), preferably at least one of the locking components is deformable, in particular elastic.Insofar as the engagement of the locking components is characterized by the displacement of one locking component relative to another and an engagement between the locking components, the orientation of the deformation of at least one deformable locking component is preferably normal to the orientation of the displacement of one locking component relative to another. Preferably, the engagement of the locking components occurs during the return of the pocket plunger to the closed position. Preferably, the locking mechanism in the closed position is subjected to a load along the orientation of a third side and / or along the orientation of a second side and / or along the orientation of one side of the housing.
[0015] With regard to the pocket punch, it is also advantageous if the locking mechanism has at least one release mechanism, whereby the locking mechanism can be released by actuating the release mechanism. Preferably, the release mechanism is accessible in a closed position of the pocket punch. Preferably, actuating the release mechanism initiates the transition of the pocket punch from the closed position to the operating position. Preferably, actuating the release mechanism causes a movement and / or a deformation of the release mechanism. Preferably, actuating the release mechanism is coupled with a displacement of at least one locking component relative to another and / or the deformation, in particular elastic deformation, of at least one locking component. Preferably, actuating the release mechanism is manual.
[0016] With regard to the pocket stamp, it is also advantageous if the locking mechanism has at least one deformable, in particular elastic, locking component. Preferably, a deformable, in particular elastic, locking component is functionally connected to the trigger. Preferably, the position of a deformable, in particular elastic, locking component is independent of the position of the trigger and the other locking components. Preferably, a deformable, in particular elastic, locking component is deformed and / or displaced by actuation of the trigger. Preferably, the deformation and / or displacement of a deformable, in particular elastic, locking component is coupled to the engagement of other locking components, preferably detent or sliding elements. Preferably, a first locking component is designed as a deformable, in particular elastic, first housing part.Preferably, the first housing part is mounted on the second housing part, more preferably on a second inner surface of the second housing part. Alternatively or additionally, the first housing part can be mounted on another pocket punch element, i.e., a slide, clamping element, pad carrier, or plate carrier. Preferably, the pocket punch element provides recesses in or through which the deformable, in particular elastic, locking component, especially preferably the first housing part, is directly accessible in the closed position or via a trigger. A deformable, in particular elastic, locking component can be formed as part of one of the pocket punch elements. Insofar as a deformable, in particular elastic, locking component is part of one of the pocket punch elements, the trigger is preferably formed by a deformable, in particular elastic, wall section of the pocket punch element.The deformable wall area is preferably formed by a material taper. Alternatively, the entire pocket stamp element is preferably deformable, especially elastically designed.
[0017] Regarding the pocket stamp, it is advantageous if the trigger is positioned on the housing. The pocket stamp can thus be held by the housing, opened with the same hand by pressing the trigger, and used to produce a stamp impression; the arrangement of the trigger on the housing facilitates one-handed operation of the pocket stamp. Alternatively, the trigger can be integrated into the pad holder or plate holder. Preferably, the position of the trigger is independent of the positions of other routing components.
[0018] With regard to the pocket stamp, it is advantageous if the trigger is designed as a pressure element. The pressure element is preferably actuated by a pressure load that is essentially perpendicular to the surface on which the pressure element is positioned. Alternatively, the trigger is designed as a sliding element. Preferably, the sliding element is displaceable along the orientation of a third side and / or along the orientation of a second side and / or along the orientation of one side of the housing.
[0019] With regard to the pocket plunger, it is advantageous if the locking mechanism is closed by returning the plunger from the operating position to the closed position. Preferably, this return is achieved by pivoting the plate carrier and / or cushion carrier. Preferably, the return of the plunger from an operating position to the closed position counteracts the restoring force of the clamping element. Preferably, the engagement of at least two locking components is coupled to at least parts of the return mechanism. Preferably, the return of the plunger from the operating position to the closed position causes a movement and / or deformation of the trigger corresponding to its actuation.
[0020] Regarding the pocket punch, it is also advantageous if the locking mechanism can be released by actuating two triggers, the triggers being positioned on opposite outer surfaces of the pocket punch. Alternatively, the locking mechanism is activated by actuating a single trigger. If the locking mechanism is activated by actuating a single trigger, this trigger is preferably positioned on an outer surface oriented parallel to the axis of rotation of the plate carrier. Alternatively, the trigger can be arranged in at least one area resulting from recesses in several pocket punch elements.
[0021] Regarding the pocket stamp, it is also advantageous if the locking mechanism can be released by actuating two triggers, the triggers being positioned on opposite first or second outer surfaces of the housing. Preferably, the triggers are positioned on outer surfaces of the second housing part.
[0022] With regard to the pocket punch, it is also advantageous if the locking mechanism comprises a first locking or sliding element and a second locking or sliding element, wherein the first locking or sliding element and the second locking or sliding element are engaged with each other in the closed position of the pocket punch. Preferably, the locking or sliding elements are locking components. Preferably, at least the first or the second locking or sliding element is coupled with at least one deformable, in particular elastic, locking component, especially preferably the clamping element. Preferably, at least the first or the second locking or sliding element is deformable, in particular elastic. Preferably, at least the first or the second locking or sliding element is designed as a latch. Preferably, at least the first or the second locking or sliding element is designed as a hook.Preferably, at least the first or the second locking or sliding element is designed as an eyelet. Preferably, at least the first or the second locking or sliding element is designed as a locking strip. Particularly preferably, at least the first or the second locking or sliding element is formed on the inside or an edge of a pocket stamp element.
[0023] Regarding the pocket stamp, it is also advantageous if the return of the pocket stamp from the operating position to the closed position is achieved by a torque acting between the ink pad carrier and the housing. Alternatively, the return of the pocket stamp from the operating position to the closed position is achieved by a torque acting between the plate carrier and the housing. Preferably, the torque is generated by one-handed operation by the operator. Preferably, the housing is fixed relative to the plate and / or ink pad carrier, and the plate or ink pad carrier is subjected to a force along the orientation of the second outer surface of the plate or ink pad carrier. Preferably, at least two locking components are engaged from an angle of 1–45° between the ink pad side of the ink pad carrier and the impression surface of the plate carrier until the closed position is reached.Preferably, the return of the pocket plunger to a closed position requires a moment extremum while at least two locking components are engaged.
[0024] Regarding the pocket punch, it is also advantageous if the pocket punch has a slide, the movement of which is guided along the housing, with at least sections of the movement of the plate carrier and sections of the movement of the ink pad carrier during the transition of the pocket punch from a closed position to an operating position being coupled to the movement of the slide. Preferably, at least sections of the movement of the plate carrier and sections of the movement of the ink pad carrier during the return of the pocket punch from an operating position to a closed position are also coupled to the movement of the slide. Preferably, the distance of the slide to a third inner surface of the housing is smallest in the closed position of the pocket punch and greatest in the operating position of the pocket punch. Preferably, the ink pad carrier also has a toothed section, in particular a gear segment.Preferably, the slide engages with the clamping element and / or the cushion support and / or the plate support and / or the housing via teeth. Preferably, the slide has teeth. Particularly preferred is the engagement of the slide with the cushion support via teeth. Preferably, the slide is subjected to the restoring force of the clamping element at a first end. Particularly preferred, the slide has a receiving device for receiving the clamping element. Preferably, the slide engages with the plate support at a second end. Particularly preferred, the slide has at least one guide pin at its second end. Preferably, the movement of the slide is pronounced along the orientation of a third side of the housing. Preferably, the movement of the slide is translational. Preferably, the slide has guide grooves.Preferably, a first and / or a second inner side of the housing has guide rails that engage with the guide grooves and guide the movement of the slide.
[0025] With regard to the pocket punch, it is also advantageous if the restoring force of the clamping element exerts a linear force on the slide along its direction of movement, even in the closed position of the pocket punch. Preferably, the restoring force is oriented essentially along the movement of the slide. Preferably, the restoring force of the clamping element is oriented along the third side of the housing. It is also advantageous if the clamping element is made of metal or, alternatively, of the same material as the housing, the plate carrier, the cushion carrier, and the slide. Preferably, the clamping element is designed as a tension-compression spring. Preferably, the clamping element is designed as a coil spring. Alternatively, the clamping element can be designed as a torsion spring. Preferably, the clamping element can be part of the housing, in particular the first or second housing part, or of the slide, the cushion carrier, or the plate carrier.Preferably, the clamping element loads two of the pocket punch elements. Preferably, the base of the housing, in particular the base of the first or second housing part, has a receiving device designed to accommodate the clamping element. Preferably, the receiving device secures the clamping element laterally, i.e., perpendicular to the longitudinal dimension of the housing. Preferably, the receiving device consists of an open outer limiting cylinder and an inner limiting cylinder. Preferably, the clamping element can be inserted into the receiving device from above, i.e., from an upper open end of the housing. Preferably, a receiving device for the slide is located opposite the receiving device of the housing, so that after the clamping element has been inserted into the receiving device of the housing, the slide can be inserted from above, i.e., from the upper open end of the housing.The clamping element can be inserted into the housing from an open end in such a way that it is positioned between the housing's receiving device and the slide's receiving device. Preferably, the clamping element is positioned centrally with respect to the base of the housing.
[0026] Compared to the known pocket stamps, the preferred design of the clamping element as a tension-compression spring with a fixed point of contact with the housing is structurally advantageous, since the latter only needs to be inserted into the housing during assembly; sliding the known torsion springs onto previously required axles and pre-tensioning before assembly is unnecessary.
[0027] Regarding the pocket stamp, a removable ink pad insert, encompassing the ink pad, is preferably incorporated into the ink pad holder. The ink pad holder insert is preferably secured by an insertion lock within the ink pad holder. This insertion lock preferably consists of locking elements on the ink pad holder and / or on the ink pad insert and / or corresponding counterparts on the other component. Compared to known pocket stamps, this avoids the contamination previously associated with changing the ink pad.
[0028] In the corresponding method for assembling a pocket stamp, the problem according to the invention is solved by inserting the clamping element into the housing, in particular into a first housing part or a second housing part, after which at least the cushion carrier, preferably also a slide, is inserted into the housing simultaneously or subsequently, wherein the clamping element is compressed or further compressed before and / or during the insertion of at least the cushion carrier. The clamping element is preferably not compressed after, but at least partially simultaneously and preferably in parallel with, the insertion of the cushion carrier into the housing, or alternatively, while only the slide is inserted into the housing.If the housing is designed in two parts, a deformable, in particular elastic, locking component, preferably the first housing part, is inserted into the second housing part, preferably before the clamping element is inserted, or alternatively, the clamping element is inserted into the first housing part, after which, particularly preferably subsequently, the first housing part is inserted into the second housing part. Preferably, the slide and the cushion support are engaged before they are inserted into the housing. Preferably, the insertion of the cushion support into the housing results in the engagement of a pin-and-hole connection between the cushion support and the housing. Preferably, the engagement between the slide and the plate support is effected simultaneously with the engagement of the plate support into the housing.Preferably, the second end of the slide is inserted into the guide groove of the plate carrier in the same movement as a bearing journal of the housing or the plate carrier is inserted into a bearing recess of the plate carrier or the housing. Preferably, the housing, and in particular the first housing part, has deformable, and especially elastic, catch tabs. Preferably, the slide has a locking wedge; more preferably, the locking wedge is formed as an extrusion extending along the side of the slide facing the second side of the housing. Preferably, the catch tabs are deformed by the movement of the locking wedge during the insertion of the slide into the housing, more preferably along a plane parallel to the orientation of the second side of the housing. Preferably, the original position of the catch tabs is restored as soon as the slide has been inserted into the housing.Preferably, the engagement of the catch tabs with the slider, particularly preferably at a contact point with the locking wedge, prevents the slider from detaching from the upper, open end of the housing. Preferably, at least one guide element, more preferably a guide rail or a guide groove, of the slider engages with at least one guide element of the housing, preferably on a first or second side of the housing, more preferably of the first and / or the second housing part. Preferably, the locking wedge of the slider has at least one guide element.
[0029] In the corresponding method for transferring a pocket punch from a closed position to an operating position and back, the problem according to the invention is solved by releasing a locking mechanism, thereby releasing the restoring force of the clamping element, whereupon the clamping element essentially drives the transfer. Preferably, the clamping element is compressed during the return of the pocket punch to a closed position. Preferably, the plate carrier and the cushion carrier are each pivoted until the operating position is reached. Preferably, the locking mechanism is closed during the return of the pocket punch. Preferably, the return of the pocket punch is driven essentially by pivoting the cushion carrier relative to the housing.
[0030] The invention will be further explained below with reference to two particularly preferred embodiments, to which it is not limited, and with reference to the drawings. The drawings show in detail:

[0037] Fig. 11 shows a perspective view of a pocket stamp of a second design form in the operating position;
[0038] Figs. 12, 13, 15, 16 are perspective views illustrating the assembly of the pocket stamp according to Fig. 11;
[0039] Fig. 14 shows a sectional view of the pocket stamp according to Fig. 11, illustrating the assembly of the housing parts with the slide and the clamping element.
[0040] Fig. 1 shows a first embodiment of the pocket stamp 1 in its operating position. Visible are the housing 2, the plate carrier 3, the ink pad carrier 4, and the slide 5 of the pocket stamp 1. The text plate 9 is mounted on the impression surface 8 of the plate carrier 1. Pressure elements 7 are positioned on the first opposing outer sides 11b of the housing 2. First locking elements 13a protrude from the open end 14 of the housing 2. These locking elements interact with the pressure elements 7 such that actuation of the latter 7 moves the first locking elements 13a into positions closer to each other. The first locking elements 13a are designed as hooks, the engagement sides 17 of which are oriented towards the first outer sides 11b of the housing 2.
[0041] Fig. 2 shows the pocket die according to Fig. 1 in a side section view. The clamping element 6 is designed as a coil spring. A first point of application of the clamping element 6 is located on the third inner side 21a of the housing 2 (in particular, the second housing part 2b). There, a receiving device designed as a conical base 15 is located, which secures the clamping element 6 laterally and simplifies assembly. A second point of application of the clamping element is located at a first end 5b of the slide 5. The first end 5b of the slide has a receiving cylinder 16 that embeds the clamping element 6. The second end 5c of the slide 5 provides guide pins 22 for engaging in a guide groove 23 of the plate carrier 3. The guide pins 22 engage eccentrically with respect to the pivot point fixed to the housing 2, which is defined by the bearing recesses 24 of the plate carrier 3 (see Figs. 7, 10).The point of engagement of the guide pin 22 within the guide groove 23 is not fixed to the plate carrier 3.
[0042] Fig. 3 shows the pocket die 1 according to Fig. 1 along the section plane AA (cf. Fig. 2). In this view, the toothing 5a of the slide 5, which is oriented against a second inner surface 20a of the housing 2, and the toothing 4b of the base 4a of the cushion carrier 4 engaging in this surface are more clearly visible.
[0043] From Fig. 7, which shows the pocket punch 1 according to Fig. 1 along an eccentric section CC (see Fig. 5), it can be seen that the toothing 4b, 5a necessary for the tooth engagement (4b, 5a) between cushion carrier 4 and slide 5 is formed eccentrically with respect to the center of the extension of the second sides 20 of the housing 2 (see Fig. 3).
[0044] The second detent elements 13b, visible in Fig. 2 and formed on the first inner surface 18 of the cushion carrier 4, are guided along a circular path to the first detent elements 13a during the return to the closed position. Simultaneously, the tooth engagement (4b, 5a) between the cushion carrier 4 and the slide 5 causes a translational movement of the slide 5 along the longitudinal profile of the housing 2, i.e., along the orientation of the third side 21 of the housing 2. The slide 5 is guided along the first inner surfaces 11a of the housing 2. The guide pins 22 at the second end 5c of the slide 5 move accordingly and cause the rotation of the plate carrier 3.
[0045] Fig. 8 illustrates a moment after the plate carrier 3 has reached an orientation corresponding to the closed position, i.e., the impression surface 8 is oriented perpendicular to the orientation of the third side 21 of the housing 2 (see Figs. 4-7). The cushion side 19a of the cushion carrier 4, however, remains at an angle to the second outer side 20b of the housing 2. While the cushion carrier 4 is also returned to an orientation corresponding to the closed position and pressed onto the plate carrier 3, the guide pins 22 continue to slide along the guide groove 23 of the plate carrier 3 towards the floor, i.e., the third inner side 21a of the housing 2 (cf. Fig. 6). The tension of the clamping element
[0046] 6 is continuously increased during the return stroke, i.e., it is axially compressed (see Fig. 6). Simultaneously, the first locking elements 13a and the second locking elements 13b are engaged, manifesting the locking 37, which secures the closed state and thus the contact between text plate 9 and ink pad 10.
[0047] Fig. 4 shows the closed position of the pocket punch 1 according to Fig. 1 and indicates a clip 25 that facilitates the transport of the pocket punch 1. The second outer surface 36 of the plate carrier 3 is flush with the second outer surface 20b of the housing 2. The user would hold the pocket punch 1 by the second housing part 2b for operation. To move the pocket punch 1 into the operating position, they would actuate the opposing pressure parts 7, preferably with their index finger and thumb. This would release the locking mechanism 37. The preload of the clamping element 6 now drives the movement of the slide 5 along the orientation of the third side 21 of the housing 2 towards the open end 14 of the housing 2. The engagement of the teeth 5a, 4b of the slide 5 in the cushion carrier 4 causes it to pivot. The guide pins 22 at the first end 5c of the slide 5 move towards the open end 14 of the housing 2.As soon as the guide pins 22 encounter a stop 26 in the guide groove 23 (see Fig. 8), the plate carrier 3 begins to rotate. The point of this stop, or the dimensioning of the guide groove segment 28, within which the guide pins 22 can move without affecting the rotation of the plate carrier 3, is to be selected, for example, such that the cushion support 4 does not obstruct the pivoting of the plate carrier 3 during the transition to the operating state. The stop point 27 of the cushion support 4 is formed on the housing 2 (in particular the second housing part 2b) and (see Fig. 2) limits the axial extension of the clamping element 6 and defines the operating position of the pocket punch 1.The stop point 27 is chosen such that the coupled movement between cushion carrier 4, slide 5 and plate carrier 3 is limited in such a way that the imprinting surface 8 of the plate carrier 3 is oriented in the said operating position essentially opposite a printing surface 29 to be printed.
[0048] Figures 6 and 7 also show the pocket stamp 1 according to Figure 1 in the closed position. A stamp pad 10 is arranged on the pad side 19a of the pad holder 4. In the closed position of the pocket stamp 1, the pad side 19a of the pad holder 4 is parallel to and facing the impression surface 8 of the plate carrier 3, so that the stamp pad 10 is in contact with the text plate 9 of the plate carrier 3. Both the orientation of the pad side 19a and that of the impression surface 8 are always perpendicular to the orientation of the first inner sides 11a of the housing 2. In the closed position, they are also perpendicular to the orientation of the third side 21 of the housing 2 (see Figures 4-7). The second outer side 19b of the pad holder 4 is in a position aligned with the second outer sides 20b of the housing 2.
[0049] Figure 8 shows that the pivoting of the pad carrier 4 during the transfer of the pocket stamp 1 according to Figure 1 from the closed position to the operating position is initiated before that of the plate carrier 3. It is also evident here that the stamp pad 10 is lifted perpendicular to a contact surface of the text plate 9. Figures 9 and 10 illustrate an exemplary assembly of the pocket stamp 1 according to Figure 1. Figure 9 shows the bearing pins 30, which, together with the bearing recesses 24, define the pivot axis of the plate carrier 3. The bearing pins 30 protrude from the open end 14 of the housing 2, similar to the first detent elements 13a. The bearing pins 30 are oriented according to the orientation of the first inner surfaces 11a of the housing 2 and face each other. It is also evident that the printed parts 7 and locking elements 13a, 13b are connected to the clamping body 31.The first housing part 2a has an upper clamping rib 31a and a lower clamping rib 31b, which clamp the clamping element 31 along the orientation of the first sides 11 of the housing 2. In the illustrated embodiment, the locking mechanism 37 comprises the locking components: clamping element 31, pressure parts 7, and the detent elements 13a, 13b. If the housing 2 is designed as a two-part assembly, the first housing part 2a is inserted into the second housing part 2b through the open, upper end 14 of the second housing part 2b and positioned so that the pressure parts 7 project through or into the housing openings 32 in the first sides 11 of the second housing part 2b. The first housing part 2a and the second housing part 2b form the housing 2. The support recess 31c rests on the positioning edge 33 (see Fig. 6) of the second housing part 2b. Actuation of the pressure parts 7 causes elastic deformation of the clamping ribs 31a, 31b.The first locking elements 13a are moved into positions closer to each other and held as long as the pressure load on the pressure parts 7 persists. If the housing 2 is made in one piece, the pressure parts 7 may have deformable wall sections. After the clamping element 6 is placed on the conical base 15 on the third inner side 21a of the housing 2, the slide 5 and cushion support 4 are brought into tooth engagement 5a, 4b outside the housing 2 and then inserted into the housing 2 through the upper open end 14. The cushion support 4 is mounted to the housing 2 by the bearing pins 12 at the base 4a of the cushion support 4. These engage in bearing recesses (not shown) on the first inner sides 11a of the housing 2, in particular on the second housing part 2b.The bearing journals 12 define the axis of rotation of the cushion carrier 4 and the toothed section 4b, which is defined as a gear segment, fixed to the housing 2. The slide 5 has guide grooves 34 facing the first inner surfaces 11a of the housing 2, which receive the guide rails 35 of the housing 2, here formed on the second housing part 2b. The clamping element 6 is now clamped between the first end 5b of the slide 5 and the third inner surface 21a of the housing. The clamping element 6 expands axially and moves the cushion carrier 4 and the slide 5 into a maximum deflection defined by the stop point 27. Now the stamp pad 10 is inserted into the cushion carrier 4. The guide pins 22 can now be inserted laterally into the guide groove 23 of the plate carrier 3, and the engagement between the bearing pins 30 of the second housing part 2b and the bearing recesses 24 of the plate carrier 3 is also accomplished in the course of the same movement.
[0050] Fig. 11 illustrates a pocket stamp 1' of a second embodiment, in which the cushion carrier 4 comprises a cushion insert 10' that can be removed from its end face (see Fig. 16). The cushion insert 10' can be removed from or inserted into the cushion carrier 4 perpendicular to the orientation of the cushion side 19a. The insertion locking mechanism 39 consists of cushion locking elements 39a of the cushion carrier and their counterparts 39b on the cushion insert 10' (see Fig. 16).
[0051] Furthermore, the pocket stamp 1 ' differs from the pocket stamp 1 by an alternative design of the housing 2 or the housing parts 2a, 2b, in particular in that, contrary to the first design, the first housing part 2a, not the second housing part 2b, has a receiving device designed as a conical base 15, into which the clamping element 6 is inserted (see Fig. 12).
[0052] Furthermore, Fig. 16 shows that it is not the plate carrier 3 but the housing 2, in particular the first housing part 2a, that comprises the bearing recess 24 of the pin-hole connection between the plate carrier 3 and the housing 2. Figs. 12 and 14 also show pronounced catch tabs 38 on the first housing part 2a, which engage with a locking wedge 40 formed on the slide 5. During the insertion of the slide 5 into the first housing part 2a, the catch tabs 38 are elastically deformed by the locking wedge 40 (see Fig. 14) along the orientation of the first sides 11 of the housing 2, in particular, they are forced apart.When the blocking wedge 40 has completely 'moved past' them downwards, the catch tabs 38 spring back to their original position and secure the slider 5 in the first housing part 2a - even without the cushion carrier 4 engaging with the slider 5 and, above all, being secured to the housing 2, preferably the second housing part 2b (by a pin-hole connection).
[0053] The design of the pocket punch 1 " makes assembly easier compared to the pocket punch 1, in particular because the preload of the clamping element 6 does not have to be held manually during assembly.
[0054] The slide 5 is also guided along the second side 20 of the housing 2, in particular the second housing part 2b, in the case of the pocket stamp 1. The locking wedge 40 has a guide groove (not shown) oriented perpendicular to the second side 20 of the housing 2, which engages with the guide rail 41 of the second housing part 2b. Alternatively, the slide 5 and the housing 2 each comprise guide elements perpendicular to the first side 11 of the housing 2, which engage with each other. A
[0055] Insofar as guide elements are pronounced on the first housing part 2a, the slide 5, and / or plate and / or cushion carrier 3 or 4 can be engaged before the housing parts 2a, 2b are joined to the first housing part 2a.
[0056] Furthermore, the design of the pocket stamp 1 allows the housing 2, in particular the second housing part 2b, to be deformed in the injection mold - even with small pocket stamp dimensions.
