Description

[0001] Magazine assembly for storing attachments that can be mounted on a support rail

[0002] The invention relates to a magazine assembly for storing attachments mountable on a support rail and a magazine comprising a magazine assembly.

[0003] Such a magazine assembly for storing attachments mountable on a support rail comprises a retaining rail having a web extending in a direction of travel of the retaining rail and two collar elements located opposite one another in the direction of travel on the sides of the web for connecting to a retaining geometry of the attachments. Furthermore, the magazine assembly comprises a stop element that can be arranged at an end region of the retaining rail.

[0004] Means for storing add-on components, in particular for storing electrical add-on components, in control cabinet, machine, and plant engineering are known from the prior art. When equipping a mounting rail, which can also be referred to as a top-hat rail or profile rail and is designed for attaching electrical add-on components in distribution boxes, the required electrical add-on components are often removed from packaging, for example a box, a bag, or a bulk container, and arranged on the mounting rail. The electrical add-on components, for example terminal blocks, are manually pushed sideways onto the mounting rail by a user, worker, or installer, or plugged in and locked.

[0005] The components are in a disorganized state at the time of removal, requiring the user to perform sorting in addition to the assembly work. The resulting time expenditure leads to significant delays in the assembly process.

[0006] Magazines for storing electrical attachments for automated assembly are already known from the prior art, as described, for example, in DE 10 2010 047 369 A1 and WO 2010 / 057768 A1.

[0007] DE 10 2020 118 829 A1 describes a packaging carton for accommodating a plurality of attachments arranged side by side in a storage chamber of the packaging in at least one row in a longitudinal direction of the packaging. The packaging carton has an ejection mechanism by which one attachment can be pushed out of the packaging carton through an opening.

[0008] However, there is no solution in the state of the art for holding attachments with different geometries on a holding rail with sufficient guide play to enable easy component removal without tilting, but which at the same time offers sufficient form fit with the attachments to prevent unintentional loosening and falling of the attachments during transport, as well as unintentional simultaneous loosening of several attachments due to static friction when removing an attachment.

[0009] The object of the present invention is to provide a magazine assembly for storing attachments, which stores attachments with different geometries in the correct position, enables easy individual removal of the attachments and prevents unintentional release of attachments during transport or individual removal of attachments.

[0010] This object is achieved by an article having the features of claim 1.

[0011] Accordingly, the magazine assembly for storing add-on parts mountable on a support rail comprises a retaining rail, wherein the retaining rail has a web running in a direction of extension of the retaining rail with two collar elements located opposite one another in the direction of extension on the sides of the web for connection to a retaining geometry of the add-on parts. Furthermore, the magazine assembly comprises a stop element that can be arranged at an end region of the retaining rail, wherein the stop element has at least one spring element that can be arranged adjacent to at least one of the collar elements of the retaining rail in the direction of extension. The at least one spring element is adapted for releasable connection to the retaining geometry of at least one of the add-on parts for pulling the add-on part off the stop element against a restoring force of the at least one spring element.

[0012] The term "support rail" can be understood here as a support made of a sheet metal or plastic profile, which is used in electrical engineering for attaching attachments in distribution boxes, control cabinets, junction boxes, etc. The support rail can, for example, be a rail type according to the standard DIN EN 60715 VDE 0660-520 with the publication date of July 2018. The term "attachments" can be used here to refer to electrical equipment such as terminal blocks, relays, fuse holders, end clamps, etc.

[0013] The retaining rail is used to slidably support the attachments and can be designed similarly to the support rail and have a geometry that is at least substantially complementary to the holding geometry of the attachments, for placing the attachments on the retaining rail. For example, the geometry of the retaining rail can differ from a standardized support rail in that the collar elements of the retaining rail are slightly smaller, for example 1% to 5% smaller than the collar elements of the support rail. This can be understood to mean that either the distance between the collar elements in the direction of travel is smaller, or the actual collar elements of the retaining rail are shorter than the comparable collar elements on the standardized support rail.

[0014] The collar elements can essentially be understood as I-shaped elements, L-angles, or angle elements that are formed on both sides of the flat web along the extension direction of the flat web and extend in the extension direction with the web. Alternatively, the retaining rail can also be T-shaped, with web-shaped collar elements arranged on both sides in the extension direction of the flat web, which, together with the web, form a substantially flat support surface for the attachments. For the T-shaped design, the web can have a greater height than the web-shaped collar elements.

[0015] The stop element, which can also be referred to as an anchor element or front anchor, can be arranged at an end region of the retaining rail and has at least one spring element which can be arranged adjoining at least one of the two collar elements of the retaining rail in the direction of extension. In the assembled position, the stop element is arranged at the end region of the retaining rail and the at least one spring element is arranged adjoining at least one of the two collar elements of the retaining rail in the direction of extension. By “an arrangement adjoining at least one of the two collar elements” it can be understood here that the at least one spring element is arranged directly adjacent to at least one of the collar elements, with no or only a minimal gap between the elements in order to enable the attachments to be guided from the retaining rail to the stop element.In one example, a one-piece spring element can be arranged adjacent to both collar elements. For this purpose, the spring element can be designed as a substantially flat, plate-shaped element and arranged in the removal area of ​​the stop element. The opposite end regions of the spring element can each engage an undercut in the retaining geometry of the attachment.

[0016] In the assembled position, the stop element is arranged at an end region of the retaining rail and prevents the attachments arranged on the retaining rail from accidentally sliding over one end of the retaining rail. For this purpose, the stop element can have a stop surface which, in the assembled position, runs transversely to the direction of travel of the retaining rail. The stop element can also have an opening or receptacle which, at least in some regions, is designed to correspond to the retaining rail in order to accommodate the end region of the retaining rail. The end region can extend, for example, in a range of a few millimeters to a few centimeters, for example in a range of 5 mm to 2 cm, from one end of the retaining rail along the direction of travel of the retaining rail.

[0017] Adjacent to the end of the retaining rail and in the direction of the retaining rail, the stop element can have a web segment which can be designed similarly to the web of the retaining rail and serves as an extension of the web of the retaining rail on the stop element.

[0018] In the assembled position, the at least one spring element is arranged adjacent to at least one of the collar elements of the retaining rail. A spring element can be understood herein as an element that is formed at least partially from a resilient material, or from a non-resilient material, for example, a metal material, which, in the assembled position, is spring-loaded on the stop element. The at least one spring element is adapted for releasable connection to the retaining geometry of at least one of the attachments for pulling the attachment off the stop element against a restoring force of the at least one spring element, or alternatively, a magnetic element.

[0019] In this context, the restoring force can be understood as a force that acts on at least a portion of the spring element when an attachment is removed, if this portion is elastically deformed or displaced during the removal of the attachment. Therefore, the term "removal force" can also be used for this purpose, i.e., the minimum force that must be applied to remove the attachment from the stop element. If this minimum force required for removal is not achieved, the spring elements, or portions of the spring elements, cannot deform sufficiently elastically or are not displaced sufficiently to release the connection with the retaining geometry.

[0020] The term “pulling off” can be understood here as a removal movement of the attachment from the stop element, which is directed away from or transverse to the holding rail.

[0021] The spring element can be arranged on the stop element, adjacent to the end of the retaining rail and in the direction of the retaining rail, and serve as an extension of one of the two collar elements or both collar elements on the stop element. For this purpose, the spring element can be arranged or can be arranged on one side of the web segment, or on both sides of the web segment, on the stop element and can be designed similarly to the collar element, in particular, have an identical or similar cross-section.

[0022] In the case of a one-sided arrangement of the spring element, on the side of the web segment opposite the at least one spring element, on the stop element, either another similarly designed spring element can be arranged in the direction of extension of the further collar element, or a collar segment which is designed in the same way as the further collar element.

[0023] The area on the stop element over which at least one spring element extends can also be referred to as the removal area, because it is in this area that the attachments can be removed from the holding rail. The use of a spring element enables the attachments to be securely fixed in the removal area during transport and prevents other attachments from being pulled along when an attachment is removed. Furthermore, the spring element enables haptic feedback and additional acoustic feedback, for example a clicking sound, to the user when an attachment has been removed from the removal area due to the force curve, which initially increases linearly when an attachment is pulled off or removed from the removal area and then drops abruptly due to a spring-elastic deformation of the spring element or an element connected to it.In one embodiment, the stop element has at least two spring elements, which can be arranged in the direction of travel adjacent to one of the collar elements of the retaining rail.

[0024] In this design, a spring element is arranged on each of the two collar elements when the stop element is in the mounted position. The use of two spring elements, located opposite each other on the stop element, simplifies the removal of an attachment from the removal area without compromising the secure fixation of the other attachments on the stop element.

[0025] For this purpose, the two spring elements are adapted to interact with the holding geometry of the attachments, in particular to engage at least partially in the holding geometry of the attachments in order to prevent unwanted detachment of the attachments from the holding rail during transport.

[0026] In one embodiment, the at least one spring element, in particular both spring elements, (i) is made of an elastic material, in particular an elastomer, which may have a Shore hardness in a range from 40 to 60. Alternatively, the at least one spring element, in particular both spring elements, (ii) is made of a metal or plastic material or of a recyclable, reusable, or biodegradable material, which can be arranged on the stop element with a spring force applied to it.

[0027] The at least one spring element, in particular both spring elements, can also be designed at least partially from a spring sheet.

[0028] The at least one spring element can be deformed at least in part by the tensile and compressive load that occurs when an attachment is removed or pulled off at the removal area, or can be displaced against a spring force in order to enable easy removal and, after removal, can return to the original, undeformed shape of the spring element or position.

[0029] In one embodiment, the at least one spring element, in particular the two spring elements, is designed at least in regions as a band, rope, Bowden cable or as a foam block and / or furthermore is designed at least in regions as a lamellar, lip-shaped, comb-shaped, herringbone-shaped or brush-shaped.

[0030] For example, a first region of the spring element, which is designed as a band, rope, Bowden cable or as a foam block, can be arranged on a second region of the spring element by means of a film hinge.

[0031] By means of cuts vertically or at an angle to the direction of travel, the spring element can be further divided into sub-areas in order to enable an attachment part to be easily removed from the removal area with little force required, without impairing the secure fixation of the other attachment parts on the stop element.

[0032] In further embodiments, the at least one spring element, in particular the two spring elements, is designed in the form of a strip or in the form of a leaf spring.

[0033] In one embodiment, a width of the at least one spring element, in particular of the two spring elements, in the direction of extension, or a width of a partial region of the at least one spring element, in particular of the two spring elements, in the direction of extension, corresponds substantially to a width of one of the attachments.

[0034] In the assembled position, the free end of the spring element is aligned with the outer edge or is set back from it. In particular, the contour of the spring element is adapted to correspond to the mounting geometry of the attachment parts.

[0035] In one embodiment, the at least one spring element, in particular the two spring elements, are designed to run obliquely, in particular wedge-shaped, at least in some regions in the direction of the retaining rail.

[0036] An "oblique, particularly wedge-shaped configuration" can be understood as a geometry of the spring element that is configured to be oblique, particularly wedge-shaped, in cross-section at least in some areas. This oblique configuration can be created by outer surfaces of the at least one spring element that form a substantially acute angle. The acute angle can assume any value between 0° and 90°. With the tip configured in this way, the at least one spring element can extend at least in some areas into the receiving geometry of the attachments.

[0037] The inclined configuration allows for more secure engagement of the at least one spring element in a retaining geometry, in particular in an undercut in the retaining geometry, of the attachments. In one configuration, the at least one spring element, in particular the two spring elements, and the collar elements are adapted to engage, at least in some areas, in an undercut in the retaining geometry of the attachments. In particular, the at least one spring element has a spread that essentially corresponds to the undercut in the retaining geometry.

[0038] Due to the elastic deformability or spring mounting of at least one spring element, the engagement of the spring element in the undercut can be released and the corresponding attachment removed. The non-elastically deformable material of the collar elements, in one embodiment, allows the attachments to be securely held on the retaining rail.

[0039] In one embodiment, the at least one spring element can be received in a retaining groove on the stop element. In particular, the two spring elements can each be received in a retaining groove on the stop element. In the mounted position, the at least one spring element is received in the retaining groove on the stop element. In particular, the two spring elements are each received in a retaining groove on the stop element.

[0040] The retaining groove can run parallel to the web segment on the stop element and allow the spring element to be inserted into the retaining groove. In the inserted position, the retaining groove can securely hold the spring element. By accommodating at least one spring element in a retaining groove, the spring element can be detachably connected to the stop element and held securely. The detachable connection enables easy replacement of the spring element, for example, in the event of wear or to engage a specific retaining geometry of an attachment. Furthermore, the detachable connection enables non-destructive removal of the spring element from the stop element.

[0041] In one embodiment, the at least one spring element, in particular the two spring elements, and the collar elements have a similar spread, in particular the at least one spring element, in particular the two spring elements, and the collar elements are each designed to be arranged flush with at least one of their respective outer edges.

[0042] Essentially, the at least one spring element and the collar elements can differ in the materials used, i.e., elastic or non-elastic material, but otherwise have a similar structure. In a further embodiment, the at least one spring element, in particular the two spring elements, together with the retaining groove, in particular retaining grooves, can have a similar cross-sectional geometry to the collar elements.

[0043] In one embodiment, the stop element has a stop surface, in particular a stop surface extending orthogonally to the direction of travel, for the attachments.

[0044] The stop surface prevents the attachments arranged on the support rail from accidentally sliding over one end of the support rail.

[0045] In one embodiment, the stop element has a pressure element, in particular a roller spring, for pressing at least one attachment part against the stop surface.

[0046] For example, the roller spring can rest on the retaining rail at least in part.

[0047] In one embodiment, the stop element has a handle element.

[0048] A handle element allows improved handling of the magazine assembly by the user.

[0049] In one embodiment, the direction of travel of the retaining rail runs obliquely to a plane, in particular a horizontal plane, on which the retaining rail can be arranged.

[0050] The inclined direction of travel allows the electrical attachments to slide down after an electrical attachment has been removed from the retaining rail or from the removal area of ​​the stop element.

[0051] In one embodiment, the magazine assembly comprises a holder which is adapted for detachable connection to the holding rail and which is adapted to hold the holding rail at an incline, in particular at an incline of greater than 5°, relative to a flat surface on which the holder is arranged.

[0052] The bracket can also be referred to as a holding block and can be connected to the holding rail by means of corresponding coupling elements to enable a detachable mechanical connection between the bracket and the holding rail. For example, the coupling elements can be engaged with each other by means of a sliding and / or rotating movement and can be locked directly or indirectly in a locked position.

[0053] The holding rail can be held with a slight gradient or with a slight incline in order to allow the electrical attachments to slide down after an electrical attachment has been removed from the holding rail or the removal area of ​​the stop element.

[0054] In one embodiment, the magazine assembly has a sliding element that can be arranged displaceably along the direction of travel on the holder rail.

[0055] For example, the sliding element can be arranged displaceably on the web of the retaining rail and have a holding structure adapted to engage behind the collar elements in order to displace the attachments in the direction of the stop element. Alternatively, the sliding element can also be guided along the running direction via a differently designed linear guide, such as in an elongated hole in the material of the retaining rail that extends in the running direction.

[0056] The term "sliding element" can be understood as a displaceable element that can be pin-shaped, finger-shaped, or cylindrical and that can be arranged on the retaining rail so that it can move along the direction of travel. For example, the sliding element can be arranged at one end of the retaining rail with a spring load and press the attachments towards the opposite end region with a spring force in order to advantageously ensure that the other attachments arranged on the retaining rail slide down when an attachment is removed. Alternatively, the sliding element can also be arranged on the retaining rail without a spring and, for example, ensure that the attachments slide down solely through its own weight, for example when the retaining rail is arranged with a gradient.Furthermore, the invention relates to a magazine for storing attachments mountable on a support rail, comprising: a magazine assembly as described herein and a plurality of similar or different attachments.

[0057] In one embodiment, the plurality of attachments each have a holding geometry for connection to a holding rail of the magazine assembly, wherein the attachments are adapted to be held linearly displaceable in the direction of travel on the holding rail via the holding geometry.

[0058] In one embodiment, at least one of the attachments is designed as an electrical attachment, in particular as a terminal block, relay, fuse holder, and / or end holder.

[0059] The invention also relates to an assembly system comprising a magazine as described herein. In embodiments, the assembly system comprises an assembly table, a workbench, a workshop trolley, or a machine, in particular a placement machine, on or in which the magazine can be arranged.

[0060] The concept underlying the invention will be explained in more detail below with reference to the embodiments shown in the figures. They show:

[0061] Figures 1A, 1B are schematic views of a magazine assembly;

[0062] Figure 2 is a schematic view of a stop element and a retaining rail arranged thereon;

[0063] Figure 3 is a schematic view of a stop element with a

[0064] spring element;

[0065] Figures 4A - 4C are schematic side views of a stop element without and with attachment in the removal area;

[0066] Figures 5A, 5B are schematic views of embodiments of the

[0067] spring element; Figures 6A, 6B are schematic views of a flat embodiment of the

[0068] spring element; and

[0069] Figures 7A, 7B are schematic views of a curved embodiment of the spring element.

[0070] Figure 1A shows a schematic view of a magazine assembly 1 for storing attachments mountable on a support rail according to one embodiment.

[0071] In the embodiment shown, the holding rail 3 has a web 31 running in a direction V of the holding rail 3 with two collar elements 33A, 33B opposite one another in the direction V on the sides of the web 31 for connecting to a holding geometry of the attachments (not shown).

[0072] The holding rail 3 shown is designed similarly to the support rail (not shown) on which the attachments are finally mounted. The support rail is a so-called "top-hat rail" according to the standard DIN EN 60715 VDE 0660-520 with the issue date 2018-07. The geometry of the holding rail 3 used in the embodiment shown differs from the standardized support rail in that the collar elements 33A, 33B of the holding rail 3 are slightly smaller, for example 1% to 5% smaller than the collar elements of the support rail. In the embodiment shown, the distance between the collar elements 33A, 33B in the direction of travel is smaller than the distance between comparable collar elements on the standardized support rail. The collar elements 33A, 33B shown can thus easily engage in a holding geometry of the attached attachments and hold the attachments slidably on the holding rail 3.In the illustrated embodiment, the collar elements 33A, 33B are I-shaped and run on both sides along the direction V on the flat web 31.

[0073] In the embodiment shown, a sliding element 7 is slidably arranged on the retaining rail 3. For this purpose, the sliding element 7 has a holding structure 71 for engaging behind the collar elements 33A, 33B in order to slide the attachments in the direction of the stop element 5 shown, in order to ensure that the remaining attachments arranged on the retaining rail slide forward when an attachment is removed. For sliding the attachments, the sliding element 7 has a sliding surface 73. The attachments can be pushed onto the retaining rail 3 at the opposite end regions of the retaining rail 3 in order to equip the retaining rail 3 with attachments, and can also be removed again.

[0074] In the embodiment shown in Figure 1A, the stop element 5 is arranged at an end region 35 of the holding rail 3 and has a stop surface 51 against which the attachments rest and can be removed by the user. In the embodiment shown, a handle element 53 is also arranged on the stop element 5. In the embodiment shown, the stop element 5 is made of a plastic material, and the holding rail 3 is made of a metal material. In further embodiments, the stop element 5 and the holding rail 3 are made of the same material, either a plastic material or a metal material.

[0075] Figure 1 B shows a plan view of the stop element 1 shown in Figure 1 A, which is connected to the end region 35 of the holding rail 3.

[0076] In the mounted position shown, the stop surface 51 extends transversely to the direction of travel V of the retaining rail 3. The stop element 5 has a receptacle 56, which is configured at least partially to correspond to a cross-section of the retaining rail 3 in order to receive the retaining rail 3 at its end region 35. The receptacle 56 is shown in detail in Figure 3.

[0077] In Figure 1B, the stop element 5 is shown without spring elements. The spring elements can be arranged in the illustrated retaining grooves 55A, 55B of the stop element 5. Adjacent to the end of the retaining rail 3 and in the direction V of the retaining rail 3, the stop element 5 has a web segment 54, which is designed similarly to the web 31 of the retaining rail 3 and serves as an extension of the web 31 of the retaining rail 3 on the stop element 5. Furthermore, the retaining grooves 55A, 55B for holding the spring elements are each arranged adjacent to one of the collar elements 33A, 33B as an extension of the collar elements 33A, 33B.

[0078] The area on the stop element 5 over which the spring elements extend in the holding grooves 55A, 55B, i.e. the area between the stop surface 51 and the end of the holding rail 3 received in the stop element 5, is the removal area 59 in which the add-on parts that are pushed from the holding rail 3 onto the stop element 5 can be removed. Figure 2 shows a schematic view of a stop element 5 and a holding rail 3 arranged thereon according to the previously shown embodiment. Figure 2 shows the magazine assembly 1 from Figures 1A and 1B. In Figure 2, spring elements 57A, 57B are arranged in the holding grooves 55A, 55B already shown in Figure 1B. The spring elements 57A, 57B in the holding grooves 55A, 55B, which are arranged adjacent to the end of the holding rail 3 and in the direction of travel V of the holding rail 3, serve as an extension of the two clamp elements 33A, 33B in the removal area 59.For this purpose, the spring elements 57A, 57B are arranged, as shown, on one side of the web segment 54 on the stop element 5 and are designed in cross section similar to the collar elements 33A, 33B of the holding rail 3.

[0079] Also arranged on the stop element 5 is a pressure element 61 designed as a roller spring for pressing at least one attachment part against the stop surface 51.

[0080] Figure 3 shows a schematic view of the stop element 5 according to the previously shown embodiment, wherein the spring element 57B is only partially inserted into a retaining groove 55B of the stop element 5. The retaining groove 55B in the shown embodiment is formed from two wall elements, wherein the spring element 57B can be inserted between the two wall elements and is held in the inserted position by the wall elements. The spring element 57B shown is wedge-shaped in its extension direction. Furthermore, a number of clamping elements 63A - 63N are shown on the stop element 5 in the region of the receptacle 56, which can be connected to the end region of the retaining rail in order to arrange the retaining rail on the stop element 5.

[0081] Figures 4A - 4C show schematic side views of the stop element 5 according to the previously illustrated embodiment, without and with attachment part 100 in the removal area 59.

[0082] Figure 4A shows the stop element 5 without the attachment in the removal area 59. The spring elements 57A, 57B are shown in cross-section. The ends of the spring elements 57A, 57B that extend from the web segment 54 and from the holding grooves 55A, 55B are wedge-shaped to engage in an undercut 101A, 101B in the holding geometry of the attachment 100, which, as shown in Figure 4B, is located in the removal area 59 of the stop element 5 and rests on the stop surface 51 and is further held in the position shown by the spring elements 57A, 57B. The user can pull the attachment 100 shown in Figure 4B off the stop element 5 against the spring force of the spring elements 57A, 57B. When removed, the spring elements 57A, 57B deform in order to release the engagement in the holding geometry of the attachment part 100.After removal, the spring elements 57A, 57B return to their original, undeformed shape due to their elastic design.

[0083] Figure 4C shows a detailed view of the spring element 57A shown in Figure 4B, which engages in the undercut 101A in the holding geometry of the attachment 100. As shown, the attachment 100 rests on a region of the spring element 57A, and the wedge-shaped tip of the spring element 57A is located in the undercut 101A. Furthermore, Figure 4C shows that the attachment 100 also rests on a region of the holding groove 55A.

[0084] Figures 5A and 5B show schematic views of embodiments of the spring elements 57, 57'. The spring elements 57, 57' shown have a plurality of corresponding incisions in opposite sides of the surfaces of the material for dividing the spring elements into subregions 57A-57N, 57A'-57N'. In the embodiments shown, a width of one of the shown subregions 57A-57N, 57A'-57N' essentially corresponds to a width of the attachments held in the magazine assembly. Figure 5A shows an embodiment with comb-shaped subregions 57A-57N, and Figure 5B shows an embodiment with herringbone-shaped subregions 57A'-57N'.

[0085] Figures 6A and 6B show schematic views of a flat embodiment of the spring element 57.

[0086] Figure 6A shows a schematic view of a stop element 5 and a retaining rail 3 arranged thereon according to the previously shown embodiment. The spring element 57 shown in Figure 6A is designed as a single piece, essentially flat, plate-shaped element, and is arranged in the removal area 59 of the stop element 5. The opposite end areas of the spring element 57 shown are each adapted to engage an undercut in the retaining geometry of an attachment part (not shown).

[0087] The spring element 5 in the illustrated embodiment is formed, at least in part, from an elastic material to allow the user to pull the attachment off the stop element 5 against the spring force of the spring element 57. During the removal process, the spring element 57 deforms to release the engagement with the retaining geometry of the attachment. After removal, the spring element 57 returns to its original, undeformed shape.

[0088] Figure 6B shows a cross-sectional view of the spring element 57 shown in Figure 6A.

[0089] Figures 7A and 7B show schematic views of a curved embodiment of the spring element 57.

[0090] The spring element 57 shown in Figure 7A is designed as a PVC strip and is arranged in an arc shape in the stop element 58. Optionally, in order to save material and to influence the spring-elastic properties of the PVC material, a recess 551 can also be introduced into the material of the spring element 57, as shown in Figure 7A by means of a dashed line. As in the embodiment previously shown in Figure 6A, the opposite end regions of the spring element 57 shown are each adapted to engage in an undercut in the holding geometry of an attachment (not shown). When pulled off, the spring element 57 deforms in order to release the engagement in the holding geometry of the attachment. After pulling off, the spring element 57 returns to its original, undeformed shape.

[0091] Figure 7B shows a cross-sectional view of the spring element 57 shown in Figure 7A.
