Description

"Mounting aid"

The invention relates to a mounting aid for mounting a snap ring or anti-creep ring and a method for mounting a snap ring or anti-creep ring with such a mounting aid.

Devices are known with which the mounting of an annular structure can be carried out. For example, US 4,141,129 A discloses a mounting aid for mounting an O-ring in which the O-ring can be slid along an interior of a mounting aid, the O-ring being initially skewed in the interior space and pushing along a plunger of the interior is shifted in a slanted orientation. The mounting aid of US 4,141, 129 A has a stop arranged on the end, which must be aligned with the groove in which the O-ring is to be placed. If the O-ring is moved through the interior, it abuts the stop and is pressed in further movement in the groove.

Such a mounting aid has the uncertainty that not every mounting process leads to a properly seated O-ring. The use of the mounting aid requires experience and practice, since the stop must be aligned to the intended seat for the O-ring accordingly; The O-ring is not visible during mounting in the groove, since the O-ring is present in the interior and is moved there. The required experience and practice makes the Montierhilfe known from US 4,141, 129 only practicable for experienced users, the Assembly process can not be considered in itself, since the O-ring is present in the interior and the success of the assembly can be assessed only when discontinuing the Montierhilfe.

Object of the present invention is therefore to provide an easy-to-use and / or simple design mounting aid, which can make it possible to mount a ring faster.

The object is solved by the subject matters of the independent claims. Advantageous developments of the subjects of the independent claims are the subject of the dependent claims and will become apparent from the following description.

The core idea of the invention is to use mutually force-biased fingers whose ends form a receptacle for a ring, a slider being provided which contacts at least one of the fingers. The slider can be moved along the finger and thereby move the end of the finger against the force and bring the fingers in a closer position to each other. By means of the slider, the force with which at least one of the fingers can be spread away from the other can be overcome and the fingers can be brought into a closer position to each other. By means of the slider, the distance between the fingers to each other and thus the size or the circumference of the end of the fingers can be varied. The receptacle for a ring at the first end of the fingers can thus be varied in terms of their scope. If the fingers are in a closer position to one another, the circumference is smaller than if the fingers are in a more distant position relative to one another. The receptacle can thus be smaller than the ring, so that it can be moved out of the receptacle or can not be held in this. A ring, which is located in the receptacle can be held in the remote position of the ends of the fingers to each other with or in the receptacle by the ring is held by means of frictional or positive engagement. The ring can be stretched or pressed to a degree in the receptacle so that the circumference of the ring is just above or below the circumference of the ring that adjusts when no force is applied to the ring. In traction, positive engagement or in the stretched or compressed form of the ring can be fed to a mounting location; the ring remains in the receptacle as a force acts on the ring so that the ring can not pass out of the receptacle. In this position, the ring can be mounted from the receptacle by the present in the recording ring at the mounting location from the recording, the ring in the receptacle may be at least partially exposed, so that the ring at the installation site can cooperate with there existing material. A process-safe positioning of the ring is possible. The invention provides an ontierhilfe for mounting a snap ring or anti-creep ring with a first finger and a second finger. The first finger and the second finger are arranged side by side. A first end of the first finger is disposed adjacent a first end of the second finger. The first end of the first finger may be brought closer to a position closer to the first end of the second finger, against a force from a position farther from the first end of the second finger. The first end of the first finger and the first end of the second finger, at least when the first end of the first finger is in closer proximity to the first end of the second finger, form a receptacle for a ring. A slider is provided which contacts the first finger and which can be slid from a position farther from the first end of the first finger into a position closer to the first end of the first finger. The slider brings the first end of the first finger against a force from the position farther from the first end of the first finger into the position closer to the first end of the first finger.

For the purposes of the description, a snap ring or an anti-creeping ring is to be understood as an annular, in particular elastic, element. In particular, the ring may be substantially a metal ring. In particular, the ring may consist essentially of spring steel wire. In particular, the ring may be a snap ring as a retaining ring for screw connections. For the purposes of the description, the term "snap ring" also encompasses a shaft safety ring or a bore safety ring. For the purposes of the description, the term "ring" is not restrictive in terms of its geometry, since in the case of a snap ring or an anti-creeping ring it is also understood to be circular Form deviating geometries can be provided, such as radially or axially wavy rings, but also oval or elliptical shapes. It can be provided in particular that the ring is designed to be open over a section, so that the ring does not have to be circumferentially closed. The term "anti-creep ring" in the sense of the description also includes an annular element, which in particular can reinforce a panel of soft material, which may be made of plastic, for example.

For the purposes of the description, the term "finger" encompasses a finger-shaped component which can be designed as an elongated component If the description states that the first finger and the second finger are arranged next to one another, this arrangement comprises the arrangement of the two fingers The fingers may be arranged about a longitudinal axis, with the two fingers being arranged parallel to the longitudinal axis or with little deviation from the longitudinal axis about the longitudinal axis one of the fingers is arranged parallel to a longitudinal axis and only one of the fingers can take a deviation to the longitudinal axis. One of the fingers can be arranged rigidly to the longitudinal axis, while the other finger can describe a variable angle to the longitudinal axis in order to be able to be changed between the more distant position and the closer position. Deviations from the longitudinal axis or the common extension in substantially the same direction include a deviation preferably less than 30 °, more preferably less than 20 °, most preferably less than 15 °. The fingers may have substantially the same length in the longitudinal direction. But it is also possible that in particular a finger substantially fixed in position is designed to be shorter or longer than the finger movable in its position. The fingers can be configured essentially the same in their design transversely to the longitudinal direction. In particular, at least one finger can have a section of a substantially circular or elliptical shape with regard to its longitudinal cross section. The two fingers can have such a respective longitudinal cross-section, that substantially results in a circular or elliptical shape when the first ends of the fingers are brought in the closer position to each other.

The fingers can be arranged symmetrically about a longitudinal axis. The fingers can be arranged equidistant about a longitudinal axis, wherein the fingers can describe different or equal circumferences about the longitudinal axis. The fingers may be fixed to each other by means of a fixation, wherein a fixation may preferably be spaced apart from the first end of the fingers so that the first ends of the fingers can assume the more distant position and / or the closer position without the effect of the fixation. The fixation may be formed integrally with one of the fingers, in particular with a finger that does not substantially move to bring the first ends into closer proximity to one another.

In particular, the fixation may be spaced from the first end of at least one of the fingers. The fixation can be realized in the form of a clamping or a cohesive connection. The finger or fingers may be connected to a base of the fixation. The fingers can be connected to each other in a preferred embodiment or are supported against each other. The

Fingers may form a negative (in open position) biased staple-like arrangement in which the fingers may form legs of the staple.

The use of ordinal numbers "first" and "second" with respect to the fingers does not expose any of the fingers as a particular finger, but merely provides one

Possibility to name and open the fingers, which can be the same to be able to fall back on named fingers. The use of the ordinal numbers "first" and "second" also does not exclude the presence of further fingers, for example a third finger or further fingers. If the first and second fingers are designed differently or there is a structural difference to the fingers, then the third finger can be designed like the first or the second finger. Each additional finger can be designed according to a shape or another shape.

For the purposes of the invention, the arrangement comprises that a first end of the first finger is arranged adjacent to a first end of the second finger, in particular the possibility that the ends are arranged close to each other and lie in a plane, in particular an angle near 90 ° to the longitudinal axis of the fingers or a longitudinal axis about which the fingers may be arranged may include.

The force against which the first end of the first finger can be brought closer from a position farther from the first end of the second finger to a position closer to the first end of the second finger may be any mechanical force applied to one or both of the fingers can work. In particular, the force can be a force exerted by an elastic element, in particular a spring. It may also be that the force is exerted by means of a lever on the first end of the second finger. A hydraulic force that must be overcome in order to bring the first end of the first finger closer from a position farther from the first end of the second finger to a position closer to the first end of the second finger may alternatively or additionally be provided.

As used herein, the term "receptacle" formed for the ring includes providing abutment points for the ring at the first end of the fingers The abutment points may extend in the radial or axial direction of the finger The receptacle can have nub-like projections as contact points, for example a receptacle with contact points directed against an inner contour of the ring can be formed In order to grip the ring securely in the receptacle, the first ends of the fingers can first be brought into a close position relative to each other and the ring can be placed on top form the recording, the slide can beabst again in one to the first end be moved situation, so that the two fingers spread again. In a preferred embodiment, the ring may be radially surrounded by the receptacle. A portion of the first ends of the fingers may at least partially surround the ring from the outside. The outer surface of the ring may be in contact with the receptacle. An additional investment at the first end of the fingers in the direction of the longitudinal axis of the fingers is possible, so even investment points can be provided which extend substantially in the axial direction of the finger or the longitudinal axis of the fingers. The receptacle can be formed at least partially from abutment points which, viewed in the circumferential direction of the ring, form an L-shaped form. At least in sections, the receptacle can be configured L-shaped, wherein the small leg of the L can be directed inwards. The ring can thus be held between the fingers. Such an arrangement allows access to the ring from the area located between the fingers.

The receptacle can support the ring in the radial and / or axial direction of the longitudinal axis of the finger, wherein slight deviations of the radial or axial direction are not excluded, which are in the range of less than 20 ° deviation, preferably less than 10 ° deviation, particularly preferably less than 5 ° deviation lie. In particular, the receptacle can be designed in such a way that the ring accommodated in the receptacle is exposed in such a way that the ring is aligned in its vertical extent (thickness) substantially parallel to the longitudinal axis of the fingers or the longitudinal axis about which the fingers are arranged is present to a greater extent outside the intake. The extension of the receptacle in the direction of the longitudinal axis of the fingers or the longitudinal axis about which the fingers are arranged is preferably adapted to the thickness of the ring such that this extent is less than 50% of the thickness of the ring, in particular less than 40%. is the thickness of the ring, and most preferably less than 35% of the thickness of the ring. In a preferred embodiment, the receptacle is configured such that the extension in the longitudinal direction of the fingers or the longitudinal axis about which the fingers are arranged is substantially equal to approximately 33% of the thickness of the ring. Preferably, the extent of the receptacle in the direction transverse to the longitudinal axis of the fingers or the longitudinal axis about which the fingers are arranged adapted to the radial extent of the ring so that this extent is less than 50% of the radial extent of the ring, in particular smaller than 40% of the radial extent of the ring, and most preferably less than 35% of the radial extent of the ring. As a result, can be accessed from the inside between the fingers on the ring and in particular a ring located in the receptacle are ejected from the receptacle.

The term "slider" in the sense of the description comprises an element which can be moved in a substantially translatory direction, essentially the slider is moved in one direction Longitudinal extension of the fingers or the longitudinal axis about which the fingers are arranged, are given. The direction can correspond to the direction of the fingers.

In a preferred embodiment, the slider comprises a rolling element or slider, the slider contacting the first finger with the rolling element or slider and the rolling element or slider moving on the first finger as the slider moves away from the first end of the first finger in which the first end of the first finger closer position is pushed. The rolling element or sliding element may in particular be a roller or a sliding surface. A roll element designed as a roll can roll on the first finger, wherein the roll can be arranged such that the roll axis is aligned substantially transversely to the longitudinal axis of the finger. The roller may have a counter element, which may in particular also have one or more rollers. There may be a constant distance between the roller and the counterpart element adapted to the spacing of the fingers with respect to the first end when the first ends of the fingers are in the closer position. The roller may be displaced with the mating member from a position adjacent the second end of the fingers towards the first end of the fingers and exert a counterforce on the finger which at least compensates for the force that can bias the fingers in the more remote position relative to one another , The counter-element roller may compress the fingers adjacent the first end. A rolling element designed as a roller can also be oriented such that the rolling axis extends substantially parallel to the longitudinal axes of the fingers or the longitudinal axis about which the fingers are arranged. The roller may be a plastic ring which can be rolled or displaced with the slider from a position farther from the first end of the first finger to a position adjacent the first end of the first finger. The diameter of the roller may be adjusted to the distance of the fingers with respect to the first end when the first ends of the fingers are in the closer position so that the roller displaced to the first end of the fingers exerts a counterforce on the finger which at least the finger Force, which can bias the fingers in the more distant position, compensated.

The sliding element may have a sliding surface, which may slide on the first finger, wherein a counter surface for the sliding surface may be provided on the first finger. The sliding element can form a sliding bearing with the first finger. The sliding surface may be configured such that the sliding surface presses the finger against the force when the sliding surface is displaced toward the first end of the finger. It can be provided that the rolling element or the sliding element is designed as a wearing part, wherein the rolling element or the sliding element may be a plastic-containing element.

It is essential to the rolling element and / or the sliding element that such an element can contact the first finger and be moved relative to the first finger and move the first end of the first finger against the force away from the first end of the first finger Position in which the first end of the first finger closer position is brought. The description here refers to a relative movement of the first end of the first finger relative to the first end of the second finger; In this case, the first finger and / or the second finger can move relative to the element and / or the slide. A relative movement of the first ends of the two fingers relative to one another can be achieved by carrying out a relative movement of both fingers to the rolling element and / or sliding element or by only one movement of a finger.

In a preferred embodiment, the slider on a rolling element or sliding element, with which the slider contacts the second finger, wherein the rolling element or sliding element moves on the second finger when the slider from the first end of the first finger remote position in the first end of the first finger closer position is pushed. As a result, a simple construction of the mounting aid can be achieved. The slider may form, with the rolling element or the sliding element which contacts the second finger, a counter element to the rolling element or sliding element which can contact the first finger. A support of the two rolling elements or sliding elements is possible. It is particularly possible that a finger of a rolling element and a finger can be contacted by a sliding element. Contacting a finger with a rolling element and a sliding element is possible.

If it is pointed out that the rolling element and / or sliding element moves on one of the fingers, then it is not excluded that also a portion of the rolling element and / or sliding element is present below or next to at least one of the fingers. The description of the term "is based on the fact that the rolling element and / or the sliding element is present at a position that can be handled or accessed by the user and that the fingers can be pretensioned to one another in the opening position of the first end. In a particularly preferred embodiment, the rolling element and / or sliding element is arranged such that the element is present in an area which is arranged around the fingers. The rolling element and / or sliding element has an action surface which contacts one of the fingers and when acted upon the first end of the finger on the first end of the other of the fingers can move. The rolling element and / or sliding element can in particular contact an outer surface or an outwardly directed surface of a finger. In particular, an outer surface or an outwardly directed surface may be a surface extending radially from the longitudinal axis of the finger or the longitudinal axis about which the fingers may be arranged.

In a preferred embodiment, the slider at least partially surrounds the first finger and the second finger. As a slider, an at least partially annular or elliptical ausgestaltetes element can be used. The slider may have a shape made up of sections of a ring or an ellipse. The slider may be configured in one piece or in several parts, which may be parts of a ring or elliptical shape. The slider may be formed of half-shells or other partitions or portions of a ring-like or elliptical-like shape.

In a preferred embodiment, the mounting aid has a mounting plunger which is arranged between the first finger and the second finger and which can be pushed from a position farther from the first end of the first finger into a position closer to the first end of the first finger. The term "assembly ram" as used herein comprises a tappet-like member which can be moved relative to one or both of the fingers The movement is preferably in the longitudinal direction of the fingers or along the longitudinal axis between the fingers so that the ring can pass from the receptacle and can be brought to the intended position for assembly.

In a preferred embodiment, a spreading spring is provided, which is connected at one end to the mounting plunger and abuts with another end on the first finger or abuts with the other end to one end of a pin, the other end abuts the first finger. Here, any form of force can be selected. It is also possible, in addition to an elastic element, which may be configured in particular as a spreading spring, to provide a pneumatically acting force. The provision of a pin between the spreading spring and the finger is one way to provide an indirect action of the spreading spring on the finger. In this way, in addition to an immediate action of the spreading spring on the finger an indirect action may be provided, so that the spreading spring does not necessarily have to come into contact with the first finger. By providing a spreading spring which may be connected to the mounting plunger, the possibility is created that apart from ejecting the ring from the receptacle, the mounting plunger also comes apart from the action of spreading the two fingers. With the assembly ram, the function the ejection as well as the function of biasing the finger to each other at least supported or executed. The term "end" associated with the pin also includes the meaning of the section end of the pin so that the spreading spring may abut a portion end of the pin formed by, for example, a cross-sectional change in the longitudinal direction of the pin attack in a depression of the pen.

In a preferred embodiment, the first finger has a chamfer at its first end, wherein additionally or alternatively the second finger has a chamfer at its first end. This makes it easier to pick up the ring. It can also be configured a centering aid for the ring. However, the chamfer can also be configured additionally or alternatively outside the receptacle, so that the outer contour of the fingers in the region of the first end can be reduced in order to be able to introduce the first end into narrow regions. With the outer contour of the fingers in the region of the first end, a possibility for centering the mounting aid to the mounting location of the ring is possible. For the purposes of the description, the term "chamfer" encompasses a taper, which does not necessarily have to be designed linearly, deviations are possible here Any reduction in the outer dimensions of the outer contour of the fingers can be interpreted as a chamfer.

In a preferred embodiment, a housing is provided which partially surrounds the first finger and the second finger, the housing having an end opening from which the first end of the first finger and the first end of the second finger protrude. A housing offers the possibility of simplified handling by the housing can be gripped. In addition, a protection of the arranged in the housing fingers and / or mounting plunger can be achieved with the housing. Openings and openings in the housing may allow access to the fingers and / or other elements, in particular the mounting plunger, the mounting aid, so that a maintenance and / or repair of the mounting aid can be performed without opening the housing.

The invention also provides a method of mounting a snap ring or anti-creep ring with a mounting aid as described above. The ring is inserted and held in the receptacle for a ring by sliding the slider from the position farther from the first end of the first finger into the position closer to the first end of the first finger and thereby moving the first end of the first finger away from the first finger from the first end of the second finger more distant position in the first end of the second finger closer position was brought and the ring was compressed. In a preferred embodiment, the ring held in the receptacle partially overhangs the first end of the first finger and the first end of the second finger. This allows the ring to be handled more easily. The ring is virtually free in certain sections that are not covered by the recording before. The exposed portions of the ring in the receptacle can be used for handling or interacting with a workpiece. A stripping of the ring from the mounting aid can be simplified thereby.

In a preferred embodiment, the ring is pushed out of the seat by sliding the mounting follower closer from the first end of the first finger to the first end of the second finger.

The invention will be explained in more detail with reference to an embodiment shown in the drawings.

In the drawings shows:

Fig. 5 is an enlarged view of an end portion of the device according to the invention in one of the Fig. 2 corresponding position.

Figs. 1 to 3 show a sectional view of a mounting aid for mounting a configured as a snap ring or anti-creep ring 1 from the side. The mounting aid has a first finger 2 and a second finger 3. The first finger 2 and the second finger 3 are arranged side by side and arranged with respect to a longitudinal axis L of the mounting aid. The first finger 2 and the second finger 3 extend in substantially the same direction. A first end 4 of the first finger 2 is disposed adjacent to a first end 5 of the second finger 3.

In the embodiment shown in Figs. 1 to 3, the first end 4 of the first finger 2 is against a force from a position farther from the first end 5 of the second finger 3, as shown in Fig. 1, into one of the first End 5 of the second finger 3 closer position, as shown in Fig. 2, can be brought. On the first finger 2, a force is exerted which acts in particular in the region of the first end 4 of the first finger 2. In the position shown in FIG. 1, the first end 4 of the first finger 2 is spread away from the first end 5 of the second finger 3. The ring 1 shown in Fig. 1 is not held by the mounting aid.

In order to hold the ring 1 of the mounting aid, a receptacle 17 is then formed at least at the first end 4 of the first finger 2 and at the first end 5 on the second finger 3, when the first end 4 of the first finger 2 in the closer position, 2, the first end 5 of the second finger 3 is located.

In order to change the relative position of the first end 4 of the first finger 2 with respect to the first end 5 of the second finger 3, a slider 6 is provided which contacts the first finger 2 and that of the first end 4 of the first finger 2 1) can be pushed into a position closer to the first end 4 of the first finger 2 (FIG. 2). In this case, the first end 4 of the first finger 2 is brought into a position closer to that of the first end 5 of the second finger 3, counter to a force from the position (FIG. 1) remote from the first end 5 of the second finger 3.

The slider 6 has a rolling element 7, which contacts the first finger 2. When the slider 6 is pushed from the position (Fig. 1) farther from the first end 4 of the first finger 2 into the position closer to the first end 4 of the first finger 2 (Fig. 2), the rolling element 7 can slide on the first finger 2 are moved.

Further, the slider 6 has two rolling elements 8, 9, with which the slider 6 contacts the second finger 3, wherein the rolling element 8, 9 move on the second finger 3 when the slider 6 from the first end 4 of the first finger 2 more distant position in the first end 4 of the first finger 2 closer position is pushed. The slider 6 can be supported with the rolling element 7 on the first finger 2, wherein the rolling elements 8, 9 are counter-elements for the rolling element 7. The distance of the successive outer contour of the rolling element 7 on the side of the first finger 2 and the rolling elements 8, 9 on the side of the second finger 3 defines the distance between the fingers 2, 3 with respect to their outer dimensions. The slider 6 surrounds the first finger 2 and the second finger 3 at least partially.

4 shows an enlarged view of the mounting aid in the region of the receptacle 17 at the ends on the fingers 2, 3. FIG. 4 shows the state of the mounting aid according to FIG. 1. The first end 4 of the first finger 2 is in a more distant position compared to the position shown in Fig. 5, which shows the state of the mounting aid according to Fig. 2, in which the first end 4 of the first finger 2 in a closer position to the first end 5 of the second finger 3, wherein the ring 1 is held in the receptacle 17. For this purpose, the slider 6 is pushed from the position (FIG. 4 and FIG. 1) which is farther away from the first end of the first finger 2 into the position closer to the first finger 4 of the first finger 2 (compare FIGS. 5 and 2).

The mounting aid has a mounting plunger 10, which is arranged between the first finger 2 and the second finger 3 and the one from the first end 4 of the first finger 2 remote position (FIG. 2) in a first end 4 of the first finger. 2 closer position can be pushed (Fig. 3), so that the located in the receptacle 17 ring 1 can be pushed out of the receptacle 17.

In a transverse to the longitudinal axis L arranged on the mounting hole a spreading spring 11 is provided in the mounting plunger 10, which is connected at one end to the mounting plunger 10 and rests with the other end to a pin 12, the end of which bears against the first finger 2. By means of the spreading spring 1 1 and the force exerted on the pin 12 a spreading force can be exerted on the first finger 2, which brings the first finger 2 in a position such that the first end 4 of the first finger 2 in a first end of the fifth 2 of the second finger (FIG. 1). When the slider 6 is brought closer to the first position 4 of the first finger 2 from the first end 4 of the first finger 2 (FIG. 1), the rolling element 7 acts on the first finger 2 such that the pin 12 is immersed against the spring force of the spreading spring 11 in a bore in the mounting plunger 10. The first end 4 of the first finger 2 comes into a closer position to the first end 5 of the second finger 3 (FIG. 2). Other possibilities of the direction of movement of the fingers 2, 3 to each other are conceivable, but not shown. For example, a linear motion could be orthogonal to the longitudinal extent of the two fingers 2, 3

The mounting plunger 10 can be actuated by means of a handle 16, which is arranged on the end of the housing 13. The mounting plunger 10 is spring-biased in the farther position from the first end 4 of the second finger 3. In order to bring the assembly ram 10 from the farther position shown in Figs. 1, 2 from the first end 4 of the first finger 2 to the closer position shown in Fig. 3 to the first end 4 of the first finger 2, the handle 16 in this direction , along the longitudinal direction L of the mounting aid and in the direction of the receptacle 17 and the first end 4 of the first finger 2, are actuated. The handle 16 is pressed to bring the ring 1 by means of the mounting plunger 10 from the receptacle 17.

The first finger 2 has a bevel at its first end 4. The second finger 3 likewise has a chamfer at its first end 5 (compare FIGS. 4 and 5). The mounting aid also includes a housing 13 which at least partially surrounds the first finger 2 and the second finger 3, the housing 13 having an end opening

14, from which the first end 4 of the first finger 2 and the first end 5 of the second finger 3 protrude.

The fingers 2 and 3 are fixed in the housing 13 in a fixation 15. The fixation

15 is formed integrally with the second finger 3. The finger 3 can remain at rest even when the slider 6 and the handle 16 are actuated. By means of the fixing 15, the first finger 2 is movably mounted at the end.

With the mounting aid shown in FIGS. 1 to 3, a method for mounting a snap ring or anti-creep ring is feasible. The ring 1 can be inserted into the receptacle 17 for a ring and be held in that the slider 6 has been pushed from the first end 4 of the first finger 2 more remote position in the first end 4 of the first finger 2 closer position and thereby the first end 4 of the first finger 2 has been brought closer from the position remote from the first end 5 of the second finger 3 to the first end 5 of the second finger 3 and the ring 1 is held in the receptacle 17 by frictional engagement. The ring 1 can be slightly compressed in the receptacle 17. This process can be seen in the sequence of FIGS. 1 and 2.

In the method, it can be achieved that the ring 1 held in the receptacle 17 partially projects beyond the first end 4 of the first finger 2 and the first end 5 of the second finger 3. This can be seen in FIG. 2.
