Description

field of technology

The invention relates to a device for applying an abradable mass in the form of a pen according to the features of the preamble of claim 1.

State of the art

Devices of the type in question are, for example, in the form of pins which have an abradable mass, for example abradable as a result of friction. Such sticks are also known, for example, as lipsticks, but also as sticks for applying care products, in particular skin care products, or for applying medical products.

For example, it will refer to the DE 10 2016 116 134 A1 referred. It is known from this disclosure to guide a piston-like mass carrier in a moving part designed as a slotted sleeve in such a way that a direction of movement of the mass carrier in the direction of a longitudinal axis of the device can be achieved from this. Associated with an extended position of the mass carrier, the movement section of the longitudinal slot running essentially in the direction of longitudinal extent of the device transitions into a holding section running essentially at right angles to the movement section. The pin of the mass carrier is guided into this holding section in the extended position, wherein in this position the mass carrier can be prevented from moving in the direction of extension of the longitudinal axis.

From the EP 2 772 153 A1 a device for applying an abradable mass in the form of a pin is known, in which the control groove in a counter-holding cylinder ends in a funnel-shaped widening at the same surface level as is given with respect to a groove base of the control groove. From the JPH 0 712 018 U a device for applying a removable mass is known, in which strip-like, vertically running friction cams are provided.

Summary of the Invention

Based on a state of the art EP 2 772 153 A1 The object of the invention is to specify such a device which enables an advantageous interaction between the counter-holding cylinder and the pin with respect to a control groove.

This object is achieved with the subject matter of claim 1, whereby it is based on the fact that the mass carrier is accommodated in a counter-holding cylinder in which a control groove for the pin is formed on the inner wall side, and that the control groove assigned to the extended position has a transition into the cylindrical inner surface of the Has counter-holding cylinder leading inclined surface, wherein the pin in the extended position is not or only partially overlapping the inclined surface.

The device is particularly advantageous in terms of handling. The displacement of the mass carrier from the retracted position in the direction of the extended position, which is carried out as a result of user intervention, is simplified with regard to the transition of the pin guide from the movement section, which extends linearly in the axial direction, into the holding section.

The mounting section preferably also offers an extension end stop for the mass carrier, so that it is held captive in the moving part, as is further preferred.

As further preferred, with respect to the mass carrier, there may be a hindrance to movement when the pin on the mass carrier side engages in the mounting section. In the direction of the extended position, this hindrance to movement is preferably provided by a stop. In the direction of the retracted position, the prevention of movement when the pin engages in the mounting section may be provided solely by the preferably provided obtuse angle between the central axes of the moving section and the mounting section.

The transition of the pin displacement from the moving section to the holding section is simplified and facilitated by the obtuse-angled arrangement, and moreover preferably requires less force in comparison to the solutions known from the prior art.

The extent of the obtuse angle can be between 100 and 170 degrees, moreover about 110 to 130 degrees, further for example about 115 to 120 degrees.

Friction cams are preferably formed on the mass carrier, which are in frictional contact with the inner surface of the moving part when the mass carrier is moved.

As a result of the arrangement of friction cams on the mass carrier, self-locking of the mass carrier can result, in particular in an intermediate position between the retracted position and the extended position, further in particular in an intermediate position in which the pin of the mass carrier engages in the movement section which extends essentially in alignment with the longitudinal axis of the device.

The friction cams can be designed in such a way that self-locking of the mass carrier can be achieved up to a load of 6 g or more, further for example up to 8 or 10 g.

The friction cams can be formed in one piece and/or of the same material with the mass carrier in the form of projections that are raised outwards relative to an otherwise circumferential, preferably cylindrical mass carrier wall.

With reference to a movement axis of the mass carrier, which more preferably can correspond to the orientation of a longitudinal axis of the device, several such friction cams can be provided circumferentially of the mass carrier. Furthermore, these can be distributed uniformly over the circumference, but alternatively they can also be distributed unevenly.

The friction cams can also serve to improve the feel when using the device. The arrangement of friction cams can also improve overall guidance of the mass carrier in the moving part, more particularly by preventing the mass carrier from tilting in the moving part by supporting the friction cams on the inner surface of the moving part.

The mass carrier is (further) accommodated in a counter-holding cylinder in which a control groove for the pin is formed on the inner wall side and the control groove assigned to the extended position for transition has an inclined surface leading into the cylindrical inner surface of the counter-holding cylinder, the pin in the extended position not overlapping the inclined surface or only partially overlapping it.

As a result of the formation of the above-described oblique surface of the control groove at the end, there is a possibly continuous, preferably at least non-stepped, transition of the control groove into the cylindrical inner surface of the counter-holding cylinder. This can prove to be advantageous in terms of assembly, in particular with regard to the assembly of the piston. In addition, this configuration can prove favorable with regard to a possible demoulding of the counter-holding cylinder when the same is produced, for example in a plastic injection molding process.

Even if the pin overlaps only partially with the inclined surface in the extended position, a favorable interaction between the pin and the control groove results. In this way, in particular in the extended position, chip formation can be counteracted, particularly in the region of the pin on the mass carrier side. This can prove to be particularly advantageous when, as provided in a possible embodiment, the entire device or at least the mass carrier and the counter-holding cylinder are of a single type, correspondingly preferably made of the same material.

In this context, it can be provided that at least the mass carrier and the counter-holding cylinder, but also preferably the moving part and possibly a further provided closure cap are made of only one type of plastic material, in particular in the plastic injection molding process. In this regard, polypropylene (PP) can be used as the plastic.

According to a further embodiment, the holding section of the longitudinal slot in the moving part can have a latching projection which the pin of the mass carrier can run over, for holding the mass carrier in particular in the extended position.

As is also preferred, the latching projection can be overrun both when the pin enters the mounting section and in the course of a rearward displacement of the pin from the mounting section in the direction of the moving section. Thus, when the user enters the holding section and runs over the latching projection, there is haptic feedback. The overrunning of the locking projection is associated with an increased force compared to the usual displacement of the pin along the movement section, which preferably runs linearly in the axial direction, as is the overrunning of the locking projection for shifting the mass carrier from the extended position towards the retracted position. the elevated one However, the effort required to overcome the latching projection is within the usual range of effort required to actuate a device of the type in question.

As a result, in particular, of the formation of the latching projection in the region of the holding section associated with the extended position, an extended end position can advantageously result, which can only be canceled by overcoming a holding force. This can lead to an advantageous operation of the device. A normal pressure on the mass that protrudes freely beyond the counter-holding cylinder and preferably also beyond the moving part in the extended position can be intercepted by the overrunnable latching mount in the area of the mount section.

In addition, this can result in advantages with regard to filling the mass carrier with mass. Such a filling can take place in the uppermost position, in the aforementioned extended position, with the mass carrier possibly having to withstand a pressure of up to 20 Newtons, for example, in the direction of a displacement of the mass carrier from the extended position towards the retracted position.

According to a further possible embodiment, two opposite longitudinal slots can also be formed on the moving part. In a possible circular-cylindrical configuration of the moving part, the longitudinal slots can be provided diametrically opposite one another with respect to a plane oriented transversely to the longitudinal axis of the moving part.

Each longitudinal slot can also be used to accommodate a pin of the mass carrier. Accordingly, at two opposite Longitudinal slots may be provided on the mass carrier two opposite pins.

If the moving part is designed with two longitudinal slots, both longitudinal slots in the respective mounting section can have a latching projection that can be run over. The latching projections of both mounting sections can be designed in the same way.

A further mounting section can also be provided with respect to the retracted position of the mass carrier, in which case a central axis of this mounting section can also enclose an obtuse angle of, for example, 100 to 170 degrees, further for example 110 to 130 degrees, with the central axis of the movement section of the longitudinal slot.

With regard to a possible mounting section assigned to the retracted position of the mass carrier, a latching projection that can be run over in both directions can also be provided here, similar to or equal to the latching projection in the mounting section assigned to the extended position, so that the user can also practically identify when the retracted position has been reached. The overrunning of the latching projection is associated with an increased expenditure of force compared to the usual linear displacement of the mass carrier in the movement section.

The maximum retraction position is preferably reached by overrunning a latching projection that may be provided in the holding section assigned to the retraction position. As a result of a further rotational displacement of the moving part relative to the counter-holding cylinder, this can lead to damage to the device parts, in particular the pins of the mass carrier. In this context, it turns out to be appropriate advantageous if, as also proposed, the maximum achievable retracted position of the mass carrier is designed to be overrun. For this purpose, according to a preferred embodiment, the control groove in the counter-holding cylinder can end open at the edge on the foot side, ie associated with the holding section of the moving part associated with the retracted position. With continued rotational displacement of the moving part relative to the counter-holding cylinder, the pins of the mass carrier can be deflected radially inwards, so that the pins are pushed out of the control groove or out of the control grooves of the counter-holding cylinder as the associated longitudinal slots, in particular the relevant mounting sections, continue to flow through be, in order to graze thereafter as a result of further rotational displacement along the preferably circular-cylindrical inner wall of the counter-holding cylinder until it dips again in the circumferential direction into the next control groove.

Here, too, the overrunnable end position in the retracted position is conveyed to the user haptically. This counteracts damage to the device parts.

The maximum extended position of the mass carrier, on the other hand, can, as is also preferred, not be designed such that it cannot be overrun. In this maximum extended position, the respective pin of the mass carrier can be trapped between the stepped edge regions of the mounting section of the moving part and the control groove of the counter-holding cylinder.

A control groove can be formed in the counter holding cylinder for each pin. In a preferred embodiment of the mass carrier with two diametrically opposed pins, the counter-holding cylinder can be provided on the inside wall with two control grooves that optionally engage in one another in the manner of a screw thread.

The control grooves in the counter-holding cylinder can be designed in such a way that between a maximum retracted position and a maximum extended position, the moving part can rotate relative to the counter-holding cylinder by two to three revolutions, for example 2.5 revolutions, but also less than two revolutions, for example 0.5 to 1 revolution, more particularly 0.75 revolutions.

In this case, both control grooves associated with the extended position can have an inclined surface of the type described.

In a further embodiment, the friction cam can be non-circular with a longer and a shorter dimension, the longer dimension being given essentially in the direction of the movement section. The shorter dimension can be given in the circumferential direction of the mass carrier. Furthermore, the longer dimension of the friction cam can extend in the usual direction of displacement of the mass carrier.

In a further embodiment, the largest dimension in the transverse direction, ie the largest dimension of the above-described transversely directed shorter dimension, can be given eccentrically to the largest dimension in the longitudinal direction when viewed from radially outside onto a peripheral edge of the friction cam. Thus, in an installation position of the device, in which its longitudinal axis is preferably aligned essentially vertically and the opening through which the mass can be pushed outwards is directed upwards, the largest dimension in the transverse direction can be below a center of the largest dimension in the longitudinal direction be provided of the locking projection.

In a further embodiment, the peripheral edge of the friction cam can have an overall approximately teardrop-shaped contour with respect to a view from radially outside. In this case, a narrower and more pointed end area can point upwards with reference to a set-up as described above, and a teardrop arc formed in a more blunt and broader manner in comparison can point downwards.

In particular, due to the above-described design of such a friction cam, a reduced tendency to wear can be determined with the desired increased friction of the mass carrier relative to the moving part and given guidance security against tilting.

The ranges or value ranges or multiple ranges specified above and below also include all intermediate values with regard to the disclosure, in particular in steps of 1/10 of the respective dimension, ie also dimensionless if necessary. For example, the statement 100 to 170 degrees also includes the disclosure of 100.1 to 170 degrees, 100 to 169.9 degrees, 100.1 to 169.9 degrees, etc above, alternatively or additionally serve to disclose one or more singular values from a given range.

Description of the embodiments

Shown and described, first with reference to the representations in the figures 1 and 2 , a device 1 for applying an abradable mass M in the form of a pen.

The device 1 settles, as in particular in figure 2 shown, essentially composed of a mass carrier 2, a protective cylinder 3 forming a protective cover 4 and a moving part 5 together.

The moving part 5 has a longitudinal slot 6 in which a pin 7 of the mass carrier 2 is guided, the longitudinal slot 6 being composed of a moving section 8 running in the same direction as a longitudinal axis x of the device 1 and a mounting section 9 running at an angle thereto.

Furthermore, part of the device 1, which can be designed in the form of a lipstick according to the drawings, can be a cap-shaped covering part 10 for protective covering of the mass M retracted into a retracted position in a non-use position figure 1 .

As also shown, the device 1 can be shaped overall as a rotationally symmetrical cylinder with a longitudinal axis x forming the axis of rotation. A longitudinal extent in the axial direction can in this case correspond to approximately 3 to 5 times, further approximately 4 times, an outer diameter dimension viewed transversely to the longitudinal axis x.

All parts of the device 1 are preferably made from a plastic, in particular from the same plastic, in particular hard plastic, further, for example, each produced in the plastic injection molding process. For example, all parts of the device 1 can be made of polypropylene.

That also in the Figures 3 to 6 The moving part 5 shown in an individual representation is essentially made up of sections arranged one behind the other in the axial direction, which, as is also preferred, can be formed in one piece and combined from the same material. In the exemplary embodiment shown, a circular-cylindrical handling section 11 is obtained.

The handling section 11 can gradually transition into a collar section 12 with a reduced diameter compared to the handling section 11. Its outer diameter can, as is also preferred, be adapted to the inner diameter of the enveloping part 10, so that an attached enveloping part, in a preferred embodiment, is located between the handling section 11 and the collar portion 12 resulting step can be frontally supported.

In this closed position of the device, friction projections 13 provided on the outside of the wall of the collar section 12 interact with the inner wall surface of the enveloping part 10 . There is thus a frictional contact in the device closed position, which first has to be overcome in order to pull off the enveloping part 10 .

This collar section 12 is further adjoined in the axial direction by a tube-like guide section 14 with an outer diameter that is preferably selected to be smaller than the outer diameter of the collar section 12.

The outer diameter of the guide section 14 is essentially dimensionally adapted to the inner diameter of the moving part 5, the outer diameter of the moving part 5 in turn preferably being adjusted to the outer diameter of the collar section 12. This can result in a step occurring between the collar section 12 and the guide section 14, the facing end face of the overall sleeve-like moving part 5 can be supported on its free and circumferential end face.

In the area of the free end facing away from the handling section 11 , the guide section 14 can carry a circumferential, radially outwardly projecting retaining collar 15 , preferably having an outer diameter that is adapted to the outer diameter of the counter-holding cylinder 3 .

The counter-holding cylinder 3 can thus be held between the retaining collar 15 and the collar section 12 so that it is essentially non-displaceable in the axial direction, with the counter-holding cylinder 3 preferably being able to rotate freely relative to the moving part 5 about the longitudinal axis x.

In the guide section 14, two longitudinal slots 6, 6' are provided diametrically opposite one another with respect to the longitudinal axis x. These essentially extend, at least with a movement section 8, in alignment with the longitudinal axis x.

These movement sections 8 transition into mounting sections 9 and 16 at the end, with a central longitudinal axis y of such a mounting section 9 or 16 extending to a central longitudinal axis z of the movement section 8 according to the enlarged detailed illustrations in FIGS Figures 3 and 6 can include an obtuse angle α of about 110 to 115 degrees.

With reference to a plan view of the device 1, in which the longitudinal axis x is represented as a point, the mounting sections 9 of the longitudinal slots 6 and 6' associated with the free end of the guide section 14 can be provided pointing in the clockwise direction, while the end facing the collar section 12 of the guide portion 14 associated mounting portions 16 can be formed pointing counterclockwise.

In addition, the free end of the guide portion 14 in a side view according to the illustrations in FIGS Figures 3 and 6 angled upwards towards the free end pointing, while the lower mounting portions 16 extend angled downwards towards the collar portion 12.

The upper, a maximum extended position of the mass carrier 2 defining support sections 9 can end at an axial distance from the free end or to the retaining collar 15 of the moving part 5, while the lower, a retracted position defining support sections 16 can end essentially in the transition to the collar section 12, optionally run into the step plane.

Offset in the circumferential direction to the respective end regions of the mounting sections 9 and 16, the jacket wall of the guide section 14 can have bore-like openings 17. In order to improve the demouldability of the moving part 5 in the course of production, these can preferably be provided in the plastic injection molding process.

As further, in particular, from the presentation in figure 3 As can be seen, the longitudinal slot 6' extends beyond the area of entry into the upper holding section 9, preferably up to the holding collar 15, while the movement section 8 of the longitudinal slot 6, as shown in FIG figure 6 ends with a transition into the holding section 9 .

In the area of the extended longitudinal slot 6', the retaining collar 15 can be separated by a radial separation 18 for the convenient installation of the mass carrier 2.

In the Figures 7 to 13 the piston-like acting mass carrier 2 is shown in individual representations.

The mass carrier 2 initially and essentially has a peripheral carrier wall 19 and a carrier base 20 drawn in transversely thereto. In the usual operating position, for example according to FIG figure 17 , the mass carrier 2 has a pot opening 21 that is open at the top and is delimited by the carrier wall 19 and the carrier base 20 . The mass M, for example in the form of a lip balm, is accommodated in this pot-shaped section of the mass carrier 2 on the foot side.

For the form-fitting connection of the mass M to the mass carrier 2, several webs 22 pointing radially inwards can be formed on the inside of the pot, in particular on the inside of the wall of the carrier wall 19, evenly distributed over the circumference. These can, starting from the wall inner surface, with reference to a cross-section transverse to the longitudinal axis x according to figure 13 , as well as according to the in figure 13 enlarged detail view, be shaped like a blade, tapering radially inwards.

According to the exemplary embodiment shown, eight such webs 22 can be provided distributed over the circumference.

The webs 22 extend from the carrier base 20 in the axial direction and end as shown in FIG figure 12 at a distance from the free edge of the pot opening 21.

The support wall 19 extends further underneath the support base 20, for example with an axial length which can correspond to approximately half or a third of the axial length of the support wall 19 for forming the pot accommodating the mass M.

As in particular from the illustrations in the Figures 7 to 10 As can be seen, in this section extending on the underside of the carrier base 20, the carrier wall 19 cannot necessarily be provided completely circumferentially. Thus, according to the exemplary embodiment shown, two wall sections 23 with different circumferential extents can be set, viewed over the circumference.

As also shown, radially protruding friction cams 24 can be integrally formed on the outside of these wall sections 23 . Total can Distributed over the circumference, for example, three such friction cams 24 can be provided.

Each friction cam 24 can, with reference to a view from radially outside as shown in FIG figure 8 or figure 10 , essentially have a teardrop-shaped edge, i.e. a teardrop-shaped contour 25, with a longer dimension a and a shorter dimension b, the longer dimension a extending essentially in the direction of the longitudinal axis x and thus in the direction of the movement section 8 of the longitudinal slots 6 and 6 ' extends. The shorter dimension b can extend perpendicularly to this, more preferably essentially in the circumferential direction.

Furthermore, a largest dimension of a friction cam 24 along a line u running in the circumferential direction can be eccentric, more preferably with reference to the illustrations below, facing away from the mass M to be accommodated, to a center line w, which is related to a largest dimension along a line v in the longitudinal direction extend (see in particular the enlarged view in figure 8 ).

As further, in particular, from the enlarged representation in figure 12 As can be seen, there is also a teardrop shape of the friction cam 24 in relation to the radial outward elevation. The friction cam 24 bulges in the manner of a bulge, with a radially outer turning point, with reference to a vertical sectional representation according to FIG figure 12 , essentially in the region of the line u representing the greatest transverse dimension.

The maximum radial projection c of such a friction cam 24 can correspond to approximately one third to one quarter of the largest dimension of the friction cam 24 in the circumferential direction along the line u.

In addition, two diametrically opposed pins 7 are provided approximately at the axial height of the carrier base 20 on the outside of the carrier wall 19 . As shown, these can be pins 7 that are essentially circular-cylindrical and are made of a solid material.

The diameter of the pins 7 can, as is also preferred, be adapted to the clear spacing, viewed in the circumferential direction, of the marginal edges of the movement sections 8 of the longitudinal slots 6 and 6′ that face one another.

Incidentally, the mounting sections 9 and 16 are also adapted to this spacing, so that the pins 7 are also securely guided in the region of the mounting sections 9 and 16 when the mass carrier 2 is correspondingly displaced.

The counter-holding cylinder 3 is provided on the inside wall with two control grooves 26 which are offset by 180 degrees with respect to the cylinder axis x and rise along the inside wall of the casing in the form of a screw thread. These double-threaded control grooves 26 can extend over about 2.5 revolutions, preferably with a constant pitch, according to the exemplary embodiment shown, starting from the end of the counter-holding cylinder 3 facing the collar section 12 in the direction of the end overlaid by the holding collar 15.

Here, the control grooves 26 can run freely into the end face of the counter-holding cylinder 3 optionally supported on the collar section 12, while the ends facing away therefrom preferably end at a distance from the end of the counter-holding cylinder 3 on the retaining collar side.

As in particular from the illustrations in the Figures 15 and 16 As can be seen, the end of the control groove formed at a distance from the end region of the counter-holding cylinder 3 ends in an inclined surface 27 which, if necessary, ultimately merges into the inner surface 28 of the counter-holding cylinder 3 with a uniform reduction in the depth of the groove.

The mass carrier 2 is arranged in the device 1 in such a way that it is surrounded both by the guide section 14 of the moving part 5 and by the counter-holding cylinder 3 that also includes the guide section 14 .

Here, the pins 7 of the mass carrier 2 reach through the longitudinal slots 6 and 6 ′ of the moving part 5 and dip into the control grooves 26 of the counter-holding cylinder 3 with their radially outer end sections.

The friction cams 24 are in frictional contact with the inner surface 29 of the moving part 5 or the guide section 14.

As a result of this arrangement, by holding the device 1 on the counter-holding cylinder 3 and rotating the movement section 8 by grasping it in the area of the handling section 11, a relative rotary displacement can be achieved between the counter-holding cylinder 3 and the moving part 5, so that the mass carrier 2 can be moved via the pins 7 along the longitudinal slots 6 and 6 'in the direction of extension of the longitudinal axis x.

The Figures 17 to 24 show a lowest, correspondingly maximum retracted position of the mass carrier 2, as well as the mass M carried by the mass carrier 2.

As can be seen in particular from the sectional view in figure 24 As can be seen, the mass carrier 2 is supported via its pin 7 on the base of the lower mounting section 16 that defines the retracted position, if necessary directly on the step formed between the collar section 12 and the guide section 14, into which step the base of the mounting section 16 can run.

This maximum retracted position can be designed such that it can be run over, contrary to the usual direction of rotation for shifting the mass carrier 2 in the direction of the extended position. The control grooves 26 running out freely at this end of the counter-holding cylinder 3 can support this effect.

The position of the pin 7 in the lower mounting portion 16 is further exemplary in the figures 18 and 21 shown. From this it can also be seen that at least one mounting section 16 of a longitudinal slot (here the longitudinal slot 6 ′) has a latching projection 30 which the pin 7 can run over. This latching projection 30 can form a narrowing of the free passage dimension of the mounting section 16 .

The passage dimension d of the mounting section 16 reduced by the latching projection 30 can correspond to approximately 0.9 to 0.95 times the diameter dimension e of the pin 7 (cf figure 18 ).

The figure 19 shows an intermediate position in the course of overcoming the latching projection 30 by the pin 7. The latching projection 30 can accordingly only be deliberately overcome by a relative rotary displacement brought about by the user. It is possible for the locking projection 30 to run over due to the components being made of an elastic plastic material.

The mounting section 16 of the further longitudinal slot 6 does not have such a locking projection 30 in the exemplary embodiment shown.

By overcoming the locking projection 30, the mass carrier 2 leaves the retracted position and is successively advanced axially via the movement section 8 of the longitudinal slots 6 and 6' as a result of relative rotary displacement between the moving part 5 and the counter-holding cylinder 3, around the mass M via the open-designed free end of the counter-holding cylinder 3 and to move the moving part 5 also.

The maximum possible extended position is in the Figures 26 to 32 shown. Here the pins 7, after passing through the movement sections 8 of both longitudinal slots 6 and 6', are brought into the holding sections 9 set at an obtuse angle thereto. The mass carrier 2 completes a rotational movement about the longitudinal axis x by a few degrees, for example by about 10 degrees, together with the mass M that has been picked up, as it does when leaving the retracted position.

The maximum extended position is defined in the mounting sections 9 as a result of the stop limitation. As is also preferred, this maximum extended position cannot be designed so that it cannot be overrun. Thus, the respective pin 7 can be trapped between mutually facing edges of the control groove 26 and the mounting portion 9 .

As further, in particular, from the presentation in figure 29 to recognize, the maximum extended position can also be secured by a further locking projection 31 . Such a locking projection 31 can, according to the illustrated Exemplary embodiment in a mounting portion 9, here preferably in the mounting portion 9 of the longitudinal slot 6 may be provided. In the exemplary embodiment shown, the holding section 9 of the further longitudinal slot 6' is not provided with such a latching projection 31, although this is possible in a further embodiment.

The latching projection 31 can be designed essentially the same as the latching projection 30 in the area of the lower mounting section 16. In this respect, the same ratios can result between the passage dimension d, narrowed by the latching projection 31, in the area of the mounting section 9 and the diameter e of the pin 7.

The figure 30 shows an overflow situation of the locking projection 31 by the pin 7. Accordingly, the cancellation of the maximum extended position can only be canceled deliberately with user intervention by relative rotation. <b><u>List of Reference Signs</u></b> 1 contraption 27 bevel 2 mass carrier 28 Inner surface 3 counter cylinder 29 Inner surface 4 protective cover 30 locking projection 5 moving part 31 locking projection 6 longitudinal slit 6' longitudinal slit a dimension 7 cones b dimension 8th movement section c measure 9 bracket section i.e measure 10 cover part e diameter 11 handling section and line 12 collar section v line 13 rubbing protrusion w centerline 14 guide section x longitudinal axis 15 retaining collar y central longitudinal axis 16 bracket section e.g central longitudinal axis 17 breakthrough 18 radial separation M Dimensions 19 carrier wall 20 tray a angle 21 pot opening 22 web 23 wall section 24 friction cam 25 border edge 26 control groove
