Abstract

The invention relates to seating furniture.

Description

The present invention relates to a piece of seating furniture with which a person sitting in it can sit in a particularly relaxed manner.

background

Seating furniture is often used in the living area, which can also be converted into a very comfortable reclining position or a relaxation position. With conventional seating furniture, such as sofas, a footrest is extended to transfer from the sitting to the lying position, so that the feet can also be put up in a relaxed manner. In these models, the footrests are usually linked to the seat via scissor frames.

When transferring from a sitting position with an upright backrest and retracted footrest to a lying position, the backrest is tilted backwards relative to the seat and the footrest is extended via the scissor-type frame. This is the lying position. This requires a lot of space in order to be able to fully extend the backrest, which is tilted backwards.

Task

It is the object of the present invention to provide a piece of seating furniture which is designed to be space-saving and particularly comfortable.

Solution

This object is achieved according to claim 1.

The core idea of the present invention lies in a piece of seating furniture which can be converted from a sitting position into a particularly comfortable reclining or relaxation function and vice versa. For this purpose, the piece of seating furniture has at least one seat shell, whose shape cannot be changed, for accommodating a person, with a seat part which merges into the back part, a multi-part frame which accommodates the seat shell, the frame having at least one foot frame section and seat frame section, with both frame sections are mounted in an articulated manner coupled to one another, and a receiving unit on which the foot frame section and the seat shell are arranged, the receiving unit and the seat shell also being connected to one another via a coupling unit designed to be variable in length.

This is advantageous because it allows a particularly comfortable piece of seating furniture to be created. It has been shown to be particularly advantageous if the foot frame section is designed to be pivotable relative to the seat frame section via at least one axis of rotation.

Furthermore, it is advantageous that the receiving unit and the seat shell are connected to one another via a coupling unit that is designed to be variable in length. This Coupling unit connects the receiving unit to the seat shell. If the length of the coupling unit is changed, for example by shortening its length, the seat shell is lowered in relation to the original position. The seat shell is advantageously connected to the receiving unit and also to the seat frame section. Furthermore, the foot frame section and the seat frame section are designed to be coupled to one another in an articulated manner. The further articulation of the foot frame section on the receiving unit results in its pivotability relative to the seat frame section.

If the coupling unit is now reduced in its longitudinal extent, that is to say shortened, the result is initially a lowering of the seat shell. This lowering can advantageously take place on a circular path. By lowering the seat shell, the foot frame section is subjected to a tensile force that results from this. This application of tensile force is sufficiently large for the foot frame section to be pivoted out of its original folded position. By changing the length of the coupling unit, the item of seating furniture can be transferred from a basic position, which can be referred to as a sitting position, into a relaxation position.

Of course, this change in position is designed to be reversible, so that the sitting position can also be resumed at any time. This is then done, for example, by increasing the length of the coupling unit again. As a result, the seat shell is raised again and the foot frame frame section is subjected to a compressive force. By applying this compressive force, the foot frame frame section is unfolded from the Relaxation position pivoted back to the original basic position.

Particularly advantageously, the foot frame section forms the footrest when the chair is upholstered in use.

In the seating furniture described here, the footrest, ie the foot frame section, is not directly connected to the seat part and/or to the seat surface. The seating furniture item described here has the special feature that the foot frame section is coupled to the seat frame section. The seat frame section at least partially forms the armrests of the piece of seating furniture. The foot frame section is therefore arranged pivotably mounted on the respective armrest of the chair.

The seat shell is rigid in the seating furniture described here. This means that the seat part and back part are arranged at a fixed angle in the range from 100° to 120°, particularly advantageously 110°. This angle cannot be changed. A pivoting of the backrest relative to the seat part is not possible. Also, the position of the seat part relative to the backrest cannot be changed. It is only possible to change the position of the entire seat shell. This is advantageously carried out by changing the length of the coupling unit.

Further advantageous embodiments emerge from the dependent claims.

In a further advantageous embodiment, the coupling unit can be designed to be variable in its longitudinal extension hydraulically, pneumatically or by means of compressed air. This is of course not to be understood as limiting, so that it is also conceivable that the change in length of the coupling unit is formed, for example, via a spindle drive. It has been shown to be particularly advantageous if the coupling unit is controlled by a motor. In this way, the user who has taken the seat can change the seat position in any way simply by pressing a button. This can be done with a cable, for example. Consequently, the coupling unit can have at least one drive means, advantageously a motor.

In a further possible exemplary embodiment, it is conceivable that the control of the coupling unit, which can have a drive means, for example a motor, can be controlled via a cable-free connection, for example via application software (app).

In a further possible exemplary embodiment, the coupling unit can have at least one element whose length can be changed. This can be designed, for example, as a hydraulic spring, pneumatic spring, gas pressure spring or compressed air spring. The springs mentioned here are also advantageously designed such that their length can be changed by means of a drive means, for example a motor. The at least one element that can be changed in length advantageously connects the receiving unit to the seat shell. The variable-length element is advantageously part of the coupling unit.

By changing the length of the element of the coupling unit that can be changed in length, the position of the seat shell can advantageously be changed. Advantageously, by reducing the length, the seat shell and thus also the seat point can be shifted diagonally backwards and downwards. The displacement can advantageously take place along a circular path section. With this reduction in length and the associated shifting of the seat shell backwards and downwards at an angle, the folded-in foot frame frame section is pivoted upwards out of the sitting position in a particularly advantageous manner. For this purpose, the foot frame section and the seat frame section are connected to one another in an articulated manner. This is advantageously formed via two rotary joints with a common axis of rotation.

At the same time, the foot frame section is articulated on the receiving unit. This linkage is also designed with bearings. The application of tensile force, which is transmitted through the change in length of the length-adjustable element with the seat frame section to the foot frame section articulated via the axis of rotation, causes its deflection upwards.

So that the foot frame section is stable when folded out and does not wobble when the leg rest is in place, it is also arranged on two horn-like elements of the receiving unit. This arrangement is also mounted on a further axis of rotation. By changing the position of the seat shell, the first axis of rotation is also shifted.

Furthermore, in an advantageous embodiment, the receiving unit has at least one base, from which two horn-like elements extend. The base forms the base that stabilizes the seating furniture.

In a further advantageous embodiment, receiving areas are provided on opposite inner surfaces of the two horn-like elements, on which the seat frame section and/or the seat shell can be arranged. This is advantageously done via at least two recording areas. This achieves very good stability.

The two receiving areas are clearly offset from the base of the receiving unit and are therefore arranged at a distance from it. The base itself is designed to be short and compact in its vertical extension. In this way, particularly good stability and force dissipation can be guaranteed. The two horn-like elements, which are advantageously mirror-symmetrical to one another, extend out of the base.

In a further advantageous embodiment, the two horn-like elements are at least partially curved and/or twisted, extending upwards. In particular, this partial curvature and/or twisting can ensure a particularly high level of stability for the entire piece of seating furniture.

Starting from the base, the two horn-like elements extend away from each other, with a first incline obliquely upwards. A lower section of each horn-like element is formed with this first slope. The two receiving areas, to which the seat shell and/or the seat frame section is fixed, are advantageously provided on this lower section. In the simplest case, it is fixed by means of a screw connection. The seat shell and/or the seat frame section is/are advantageously designed such that its position can be changed in relation to the receiving unit.

In the further course of the respective horn-like element, the lower section is followed by an upper section. The The upper section has a significantly higher gradient than the lower section, which in contrast is rather flat. The formation of the upper and lower section of a respective horn-like element serves to stabilize it in the two positions of use and to significantly improve the dissipation of force in contrast to brackets designed in a straight line. The horn-like shape, which is based on the horns of horned animals from the animal kingdom, gives the chair a special stability and stability, even in the relaxation position. In addition, it is possible to switch between the two positions in a particularly space-saving manner.

It has been shown to be particularly advantageous for standing stability if the upper section and lower section at their transition form an angle in the range from 110 to 160°, more advantageously in the range from 135 to 145° and particularly advantageously of 140° to one another. Then the lower section is sufficiently flat and stabilizing. The upper section, on the other hand, is designed steep enough so that the pivoting of the foot frame section relative to the upper section can be carried out particularly easily and with a slight application of force.

If the upper section were too flat, for example, and spanned an angle of more than 160° compared to the lower section, a significantly higher force would have to be applied to the foot frame section and the pivot axis during the transition from the sitting position to the relaxation position, so that the foot frame section would be pivoted above. This can lead to material fatigue and malfunctions. In addition, the comfortable seating position would suffer because the foot frame frame section for a relaxed sitting would be far too low. The legs of the person sitting in the chair would therefore buckle in an uncomfortable manner.

If the upper section were too steep, for example at an angle of less than 110° with the lower section, the foot frame section would be pivoted significantly higher, so that a clearly uncomfortable relaxation position with legs arranged much too high would also result.

This is not the case with the angle ranges presented here, so that a particularly comfortable relaxation position can be assumed. It has also proven to be advantageous for the stability of the chair in the relaxed position if the seat part is positioned parallel to the lower section of the respective horn-like element in the relaxed position. This creates a compact arrangement which is also designed to be particularly stable.

In a further advantageous embodiment, towards the free ends of the horn-like elements, each of the horn-like elements can have at least one further receiving area on which the foot frame frame section can be arranged. A total of two receiving areas are advantageously provided. This means that each free end of the respective horn-like element has a receiving area on which the foot frame section can be arranged.

It has been shown to be particularly advantageous if these two other receiving areas to the free ends of the horn-like elements and / or at the free ends of horn-like elements are arranged. As a result, the pivoting of the foot frame frame section can be carried out much more quickly and facilitated.

In a further advantageous embodiment, the foot frame section is pivotably mounted on the horn-like elements, advantageously on their receiving areas. A common axis of rotation is advantageously formed by the articulation of the foot frame section on the two further receiving areas, about which the foot frame section can be pivoted in its position.

In a further advantageous embodiment, the coupling unit can change the seat height and/or the seat position of the seat shell as a function of its longitudinal extent.

2. b. Absenken der Sitzschale nach schräg hinten unten;
3. c. Ausbilden einer Kraftbeaufschlagung auf den Fußrahmengestellabschnitt; und
4. d. Verlagerung der Rotationsachse von Fußrahmengestellabschnitt und

Sitzrahmengestellabschnitt und Verschwenken des Fußrahmengestellabschnitts um eine Rotationsachse.Furthermore, the present invention also relates to a method for changing the position of the piece of seating furniture, comprising at least the following steps:

1. a. performing a change in length of the coupling unit;
2. b. Lowering the seat shell diagonally backwards;
3. c. applying a force to the foot frame base portion; and
4. i.e. Shifting the axis of rotation of the foot frame and frame section

Seat frame section and pivoting of the foot frame section about an axis of rotation.

When changing the position of the seating furniture, i.e. when it is transferred from the sitting position to the relaxation position, but of course also vice versa, shown that a particularly comfortable relaxation position for the user arises when the seat part of the seat pan is aligned parallel to the lower section of the horn-like element in the relaxation position. This parallel arrangement in combination with the coupling unit, which is shortened in length, creates a particularly stable relaxation position. It is therefore not possible for the seating furniture to tip over.

Furthermore, it is advantageous that the receiving unit and the seat shell are connected to one another via a coupling unit that is designed to be variable in length. This coupling unit connects the receiving unit to the seat shell. If the length of the coupling unit, more advantageously the length-adjustable element, is changed, for example by shortening the length, the seat shell is lowered in relation to the original position.

The seat shell is advantageously connected to the receiving unit and also to the seat frame section. Due to the shortening of the length of the coupling unit and the resulting lowering of the seat shell, the foot frame frame section experiences a tensile force application. This application of tensile force is sufficiently large for the foot frame section to be pivoted out of its original folded position.

By changing the length of the coupling unit, the item of seating furniture can be transferred from a basic position, which can be referred to as a sitting position, into a relaxation position. Of course, this change in position is designed to be reversible, so that the sitting position can also be resumed at any time. This then takes place for example by increasing the length of the coupling unit again. As a result, the seat shell is raised again and the foot frame frame section is subjected to a compressive force. As a result of this pressure force being applied, the foot frame frame section is pivoted from the unfolded relaxation position back into the original basic position, which can also be referred to as the sitting position. At the same time, the axis of rotation of the foot frame section and seat frame section is shifted back again.

5. e. Einnehmen einer Entspannungsposition mit ausgefahrenem Fußrahmengestellabschnitt und tiefliegendem Sitzpunkt unter Beibehaltung der Sitzschalenform.

Furthermore, the present invention also relates to the use of the seating furniture with at least the following steps:

1. a. Seating of a person in the seating position of the seating furniture,
2. b. Actuation of the coupling unit to change the seat position, for example by motor,
3. c. Lowering the seat shell diagonally backwards and downwards by shortening the coupling unit,
4. i.e. At the same time, the foot frame section, which is pivotably mounted on the seat frame section and which is arranged pivotably mounted relative to a respective horn-like element, is pivoted upwards out of the sitting position, and
5. e. Assume a relaxation position with the foot frame section extended and the seat point low while maintaining the shape of the seat shell.

The low seating point also contributes to improved stability of the chair in the relaxation position. It has been shown to be particularly advantageous if the seating furniture described here, which can also be moved into a comfortable reclining position, which can also be referred to as a relaxation position, is designed as upholstered furniture, more advantageously as an armchair.

In a further advantageous embodiment, a head frame section can also be arranged on the seat frame section. It has been shown to be particularly advantageous if this head frame section is formed independently of the seat frame section. This advantageously means that the inclination of the head frame frame section can be adjusted by the user, for example via latching mechanisms or other joint mechanisms.

The head frame section is particularly advantageously decoupled from the seat frame section. This means that the position of the head frame section cannot be changed as a result of the change in position of the seat part and thus also of the seat frame section.

In a further advantageous embodiment, the seat frame section can at least partially form armrests of the piece of seating furniture. For a particularly comfortable sitting position, the seat frame section is advantageously at least partially curved, advantageously double-curved. As a result, both an armrest function and a support function in the shoulder area can be provided by the seat frame section.

In a further advantageous embodiment, the seat frame section can have at least one additional guide element on each side, which is arranged over several spacer elements to the seat frame section.

In order to continue to increase the seating comfort in the relaxation position, it is conceivable that the spacer elements are curved. As a result, the respective guide element arranged thereon is raised vertically in relation to the seat frame section. This exemplary design is advantageous for the later embodiment of the seating furniture item as upholstered furniture, in particular an armchair, since this ensures a particularly wide armrest function and at the same time a support function in the shoulder area.

The double curvature of the seat frame section in its course from the armrest to the back part has also proven to be advantageous for the relaxation position. In this way, in the relaxation position, the elbows can be arranged at the lowest point after the first bend, as a result of which a relaxing posture can be adopted.

Further advantages, features and configuration options result from the following figure description of exemplary embodiments which are not to be understood as limiting.

In the drawings, elements provided with the same reference numbers correspond essentially to one another, unless otherwise indicated. In addition, there is no need to show and describe components that are not essential for understanding the technical teaching disclosed herein. In the following, the reference symbols are not repeated for all elements that have already been introduced and shown, provided that the elements themselves and their function have already been described or are known to a person skilled in the art.

Only the components are shown in the illustrations. For the sake of clarity, the upholstery is not shown if the seating furniture described here is designed as upholstered furniture, in particular as an armchair. figure 1 shows a side view of the chair 1 in the sitting position, which can also be referred to as the basic position.

The piece of seating furniture 1 has a seat frame section 2 and a foot frame section 4 pivotably mounted thereon. Both sections advantageously form the framework. In this exemplary embodiment, a head frame frame section 6 is additionally arranged. However, this can also be omitted and is therefore optional.

Furthermore, the piece of seating furniture 1 shown here has a seat shell 8 . This seat shell 8 also has a seat part 10 and a back part 12 . As in here figure 1 shown, seat part 10 and back part 12 are firmly connected to each other. A separately adjustable inclination of the back part 12 relative to the seat part 10, as is the case with known armchairs, is not possible with the chair 1 described here. It has proven to be particularly advantageous if the seat part 10 and the back part 12 form an angle α in the range from 100° to 120°, particularly advantageously 110°, to one another. This angle α is unchangeable.

Furthermore, the piece of seating furniture 1 has a receiving unit 14 . The receiving unit 14 is received and stabilized here, for example, by a base 16 .

Furthermore, the item of seating furniture 1 has a coupling unit 18 . The coupling unit 18 connects the receiving unit 14 and the seat shell 8 to one another.

Furthermore, the coupling unit 18 advantageously has at least one variable-length element 19, which is formed variable in its length L in the direction of the arrow. Through the change in length L, the distance between the seat shell 8 and the receiving unit 14 can be shortened or correspondingly lengthened.

Furthermore, the receiving unit 14 can have several receiving areas 20 , 22 . The first receiving areas 20 are advantageously formed on the receiving unit 14 for receiving the seat shell 8 . In the simple embodiment, the seat shell 8, more advantageously the seat part 10, is rotatably connected to the receiving unit 14. The mobility is required to the effect that the seat shell 8 is also inclined when the seating furniture item 1 is moved into the relaxation position. In order to compensate for this inclination, it is necessary for the seat shell 8 to be pivotably mounted on the receiving unit 14 .

The foot frame frame section 4 is also arranged coupled to the receiving unit 14 via the further receiving areas 22 . The foot frame section 4 can also be pivoted relative to the receiving unit 14 via a rotation axis (not shown).

Finally shows figure 1 also that seat frame section 2 and foot frame section 4 are formed connected to each other. Consequently, in the case of the piece of seating furniture 1 shown here, the foot frame section 4 is articulated on the seat frame section 2, which is at least partially designed as an armrest. This results in an additional visual lightness.

The foot frame section 4 is not articulated to the seat surface, as is the case with conventional armchairs.

In figure 2 13 is a front view of the chair 1 from FIG figure 1 , also shown in the sitting position. In this view it can be seen that the receiving unit 14 supports and stabilizes the entire piece of seating furniture 1 in addition to the coupling unit 18 . For this purpose, both the foot frame section 4 and the seat shell 8 are arranged on the seat part 10 on the receiving unit 14 . The arrangement of foot frame frame section 4 and seat part 10 is advantageously mounted.

This means that advantageously the seat part 10 and/or foot frame section 4 can each be pivoted about a rotation axis (not shown) relative to the receiving unit 14 . To form the respective axes of rotation (not shown), the foot frame frame section 4 and the seat part 10 are each connected to the receiving unit 14, more precisely to the two horn-like elements 24, via two receiving areas 20, 22.

The first receiving areas 20 are advantageously arranged on the opposite inner surfaces 54 of the horn-like elements 24 .

The foot frame section 4 is designed to be pivotable relative to the seat frame section 2 about the axis of rotation R1. For example, from the seated position shown here, the folded-down foot frame section 4 can be pivoted out of this position about the axis of rotation R1.

Furthermore, two guide elements 26 can optionally be provided. These two guide elements 26 are connected to the seat frame section 2 firmly connected. Guide elements 26 and spacer elements 28 are used to provide additional comfortable support surfaces for arms and shoulders in the later upholstered state of the chair 1 shown here.

The seat frame section 2 and the optionally foreseeable guide elements 26 and the spacing elements 28 thus form the armrest and also part of the backrest of the seating furniture item 1 . The two guide elements 26 are mirror-symmetrical to one another. They have a curved course. This is advantageous for a particularly comfortable laying down of the arms and a particularly comfortable leaning in the chair 1 .

In figure 3 FIG. 14 is an isometric view of seating furniture 1. FIG figure 1 shown. In addition to the previous statements, figure 3 the further axis of rotation R2 is shown, which extends through the two free ends of the horn-like elements 24 . The foot frame frame section 4 is also pivotably mounted about this second axis of rotation R2. When the folded-in foot frame section 4 is transferred into the relaxation position, it is pivoted about the two axes of rotation R1 and R2.

Furthermore, it is shown that the position of the headframe frame section 6 can be changed via an articulated connection 34 .

In this exemplary embodiment, the coupling unit 18 also has a drive means 30 in addition to the element 19 that is variable in length. This can be designed as a motor, for example.

figure 4 now shows the arrangement of the chair 1 in the relaxation position. The foot frame frame section 4 is extended so that a user can put his/her legs comfortably.

The length-adjustable element 19 is shortened in its longitudinal extent L. As a result of the shortening, the seat shell 8 is also deflected from the original seating position and transferred diagonally backwards and downwards. For a particularly comfortable relaxation position and at the same time for a high level of stability of the piece of seating furniture 1 in the relaxation position, it has proven to be advantageous for the length-adjustable element 19 to be shortened until the course of the seat part 10 is arranged parallel to the lower section 36.

For this purpose, the seat shell 8 is pivoted out of the sitting position. The pivoting takes place advantageously around the receiving areas 20.

At the same time, when the seat shell 8 is lowered, the position of the seat frame section 2 is also changed, so that the foot frame section 4 coupled to the seat frame section 2 is subjected to a tensile force in the coupling area. The axis of rotation R1 is also shifted from its original position diagonally backwards and downwards. The consequence of this is that the foot frame frame section 4, which is also pivotably attached to the free ends 40 of the horn-like elements 24, is also pivoted about this axis of rotation, which is not shown here.

The foot frame frame section 4 pivots upwards over the receiving area 22, which can be designed as a carrier, and thus also assumes the relaxation position.

Of course, this change in position is also reversible, so that the sitting position can be resumed at any time, if desired, and the foot frame section 4 can be returned to the folded state.

In figure 5 FIG. 12 is a front view of the chair 1 in the relaxation position figure 4 shown.

Both axes of rotation R1 and R2 are shown here, via which the foot frame section 4 is designed to be pivotable.

Furthermore, the third axis of rotation R3 is also shown, about which the seat shell 8 can be pivoted until the seat part 10 is arranged parallel to the lower section 36 of the respective horn-like element 24 .

Finally, the receiving areas 20 are also shown, on which the articulation of the seat shell 8 is provided. For this purpose, the receiving areas 20 are embodied as projections of the receiving unit 14 , for example. The projections can be formed in one piece with the receiving unit 14 .

This is of course not to be understood as limiting, so that it is also conceivable that, for example, carrier plates can be arranged as projections on the receiving unit 14 .

A U-shaped support system 46 is advantageously arranged in a pivotably mounted manner on these projections. The U-shaped The base of the support system 46 is firmly connected to a cross member 48 of the seat shell 8 .

It is also shown that the receiving unit 14 has a compact base 28 . This base 28 can, for example, be rotatably arranged on a base 16 .

Furthermore, the base 28 has a spreading area 44 in its vertical course upwards, at which the base 28 divides. The division takes place in such a way that two horn-like elements 24 are formed from this.

figure 6 FIG. 12 shows an isometric view of the chair 1 in the relaxation position figure 4 . Here it is particularly easy to see that the foot frame section 4 is attached rotatably to the free ends 40 of the horn-like elements 24 and that the adjustable coupling between the foot frame section 4 and the seat frame section 2 is formed. A plate carrier 32 can advantageously be arranged between the seat frame section 2 and the foot frame section 4 in order to improve the transmission of force. Advantageously, the respective guide element 26 can then also be arranged at the same time as the plate carrier 32 .

The seat shell 8 is advantageously connected to the seat frame section 2 in the upper back area. It has been shown to be particularly advantageous if this connection 51 is rigid. Furthermore, a fitting 50 for the connection between the seat frame section 2 and the head frame section 6 can be provided.

Show the following Figures 7-10 different views of the recording unit 14.

So is in figure 7 a side view of the receiving unit 14 is shown. A base 16 is provided here as an example. The base 42 is rotatably mounted on this base 16 . This is advantageous because it allows the chair (not shown) to be rotated in any direction.

The base 42 is made compact. In the side view shown here, a horn-like element 24 extends obliquely upwards, starting from the base 42 . The base merges into the lower section 36 in its course. This is rather flat in its slope.

In the further course, the lower section 36 merges into the upper section 38 . This is done by forming a clear curvature. The upper section 38 and the lower section 36 advantageously span an angle β in the range of 110-160°, more advantageously in the range of 135-145° and particularly advantageously of 140° to one another. In the angle ranges mentioned here for the angle β, particularly stable relaxation positions have been found.

figure 8 shows a front view of the receiving unit 14. The horn-like profile S of the horn-like elements 24 is shown here. The base 42 has a spreading area 44 upwards in the vertical direction. Here the base 42 divides and merges into the horn-like elements 24 .

The receiving areas 20 are provided on the inner surfaces 54 of the two lower sections 36 . In this embodiment, the projections 52 are shown.

The horn-like course S extends in each case between the two free ends 40 in the direction of the arrow. to the evident that each horn-like element 24 tapers towards its free end 40 . Advantageously, the opposing inner surfaces 54 are flat, whereas the outwardly directed outer surfaces 56 are themselves curved.

In Figure 9 and 10 two isometric views of the receiving unit 14 are shown. In figure 9 the saddle-like design of the base 42 is shown. In particular figure 10 the two axes of rotation R2 and R3 are shown again.

The base 16 can advantageously also be part of the receiving unit 14 .

Although the invention has been illustrated and described in more detail by the advantageous exemplary embodiments, the invention is not restricted by the disclosed examples. Other variations can be derived from this by a person skilled in the art without departing from the scope of protection of the invention. In particular, the invention is not limited to the combinations of features specified below, but other combinations and sub-combinations that are obviously executable for the person skilled in the art can also be formed from the disclosed features.
