Description

FIELD OF THE INVENTION

The invention relates to a universal key, such as a tool key, in particular a control cabinet key, with a plurality of key elements for opening and / or closing of known closure devices according to the preamble of claim 1 and according to the preamble of claim 7. Corresponding closure devices can in particular in or be arranged on cabinets, but also on any other technical devices, such as building services, valves, shut-off, and much more. The key or control cabinet key comprises a key body and a first key arm arranged on the key body and a second key arm arranged on the key body. At one of, in particular opposite, ends of the key arms At least one key element is arranged. Between the first key arm and the key body, a first joint is arranged, with which the arranged on the first joint key arm is pivotable about at least a first pivot axis.

Furthermore, the invention relates to a kit for mounting a key or cabinet key according to claim 21.

TECHNOLOGICAL BACKGROUND

A universal key with several key elements, such as for opening / closing of switch cabinets, the DE 87 00 493 U be removed. There, parallel joints are described, with which key arms with key elements in a common pivot axis from the body of the universal key are swung out. Especially in tight environments, ie where for the use of a key like the one according to DE 87 00 493 U little or even too little space, the user will have difficulties to operate the locking device as intended.

PRESENTATION OF THE INVENTION

Against this background, the invention has the object to improve the handling of the (universal) key described in particular insofar as the (universal) key can be used in tight environments, and as efficient and ergonomic forces and moments on the zu actuating locking mechanism are transferable. This object is achieved by a key or switch cabinet key according to claim 1. Accordingly, a second joint is arranged between the second key arm and the key body. With the second joint of the arranged on the second hinge second key arm is pivotable about a second pivot axis.

The key or universal key is suitable for actuating (opening / closing) per se known technical devices, for example for closing devices, valves and the like. At least one joint can be formed as a hinge or as a ball joint. Together, these two joints form a kind of double joint. The two joints may include features of a universal joint. It can be provided that the (first) pivot axis of the first joint with the (second) pivot axis of the second joint - unlike conventional universal joints - not (geometrically) intersect. The first and the second pivot axis preferably do not run geometrically collinear with each other but rather parallel and spaced apart. The first and second pivot axes preferably do not intersect one another geometrically. That is, the pivot axes, respectively the imaginary lines along which the pivot axes extend may be arranged so that they are not parallel to each other and spaced from each other, such as by being arranged at one and at the opposite end of the body. Accordingly, the pivoting of both key arms can take place in different ways: For example, the pivoting movement of the arms can take place within two different intersecting geometric planes. According to a variant, the pivoting movement of the first arm and that of the second arm can take place within a common (pivoting) plane.

According to a preferred embodiment it can be provided that the first key arm and the second key arm can be arranged in alignment with one another. The aligned arrangement of the key arms is given in particular when the first key arm is not pivoted relative to the second key arm or not pivoted relative to the normal position. The first joint and the second joint are preferably arranged one behind the other, wherein "consecutively" refers to the direction of the aligned key arms. If, for example, a longitudinal axis of the universal key can be defined by the key arms aligned in the normal position, then the first joint and the second joint can be arranged adjacent to one another on the longitudinal axis. The combination of first and second joint can form a double joint.

It can be provided that the orientation of the first pivot axis differs from the orientation of the second pivot axis. Preferably, the orientation of the first pivot axis for orientation of the second pivot axis may be perpendicular or nearly vertical. Accordingly, the first key arm is pivotable in a direction which differs from the pivoting direction of the second key arm, in particular by 90 ° or nearly 90 °. According to a variant of the key can be provided that the orientation of the first pivot axis and the second pivot axis to each other geometrically parallel, in particular non-geometrically collinear. Geometrically parallel here means that the imaginary lines along which the two pivot axes extend parallel to each other or almost parallel. By these imaginary lines are not collinear, the pivot axes are spaced from each other. In the variant described here, the handling of the universal key is simplified insofar as the key arms are pivotable relative to the body so that they are adjacent to each other adjacent to the key and can be arranged oriented. In particular, it can be provided according to an advantageous embodiment of the key that by pivoting the first key arm about the first pivot axis and by pivoting the second key arm about the second pivot axis of the first key arm and the second key arm offset from each other can be arranged and each other geometrically aligned in parallel. Figuratively interpreted has a key with such arranged key arms a U-shape, wherein the distance between the legs of the U of this U-shape can be very low or almost vanishing. This makes the key more compact and "handy". The key has in the parallel and mutually adjacent (u-shaped) positioning of the key arms less an elongated shape but rather a compact, almost box-like shape, whereby the key - depending on the application situation - better tangible and thus easier to handle. The user can therefore decide whether he wants to operate an elongated key with unverschwenkten key arms or a haptic compact key with both sides pivoted, side by side (parallel) aligned key arms. Finally, the user can pivot only one of the two arms relative to the body (respectively relative to the other arm), whereby a substantially L-shaped key is formed, which allows a leverage effect on the selected key element.

By pivoting the first or the second key arm about the first pivot axis or about the second pivot axis, the first key arm and the second key arm can be arranged at right angles or nearly at right angles to one another. Accordingly, the first (second) key arm, in particular by 90 ° or nearly 90 °, with respect to the body respectively relative to the second (first) key arm can be pivoted. The pivoting of a key arm relative to the body, about 90 °, causes key elements to be better actuated on one or the other key arm insofar as the pivoted key arm forms a lever element or a handle element for the other key arm. By pivoting the first key arm about the first pivot axis and (then pivoting) the second key arm about the second pivot axis perpendicular to the first pivot axis, the first key arm and the second key arm may be rectangular or nearly rectangular and (relative to the longitudinal axis of the key described above). offset from each other can be arranged. Accordingly, both key arms are pivoted relative to the body and relative to each other. The achievable offset between the first and second key arm is directed perpendicular or nearly perpendicular to the plane which is spanned by the (right angle or almost right angle) pivoted key arms.

The handling of the key described above is also improved by a key or switch key according to claim 7. Accordingly, the first joint comprises a plug-in area. It can be provided that the first and the second joint each comprise a plug-in area. The key arm has an arm plug portion and the key body has at least a body plug portion. If two joints are provided, it is expedient if the body comprises two body plug sections, the can be arranged at the opposite ends of the body. The arm plug-in portion and the body plug-in portion are, in particular by a plug-in connection, so nestled that the key arm in the body and / or the body in the key arm along the mating portion is / are pluggable. In the case of two joints, the first arm plug section can be arranged in the first body plug section and the second arm plug section can be arranged in the second body plug section or alternatively the first body plug section in the first arm plug section and the second body plug section in the second arm plug section. It can also be provided that an arm plug-in section can be arranged in a carcass plug-in section of the other carcass plug-in section in an arm plug section.

It can be provided at least one latching element or locking element for releasable latching and / or locking the connection of the key arm with the key body. The key arm is latched by means of latching element in one or more positions. For example, the key arm can be locked in a 90 ° position (or in a position with an angle of almost 90 °) relative to the carcass or to the other key arm.

In particular, the latching element may comprise one or more magnets, whereby a (magnetic) force which brings about or at least assists the latching is caused by the action of the magnet with a (magnetisable) key component or by the effect of two magnets. If a latching element comprises two magnets, one magnet is arranged in the key arm and the second magnet is arranged in the key body. The locking is redeemable. It can be provided in the region of the plug connection or of the key arm, so that the key arm and the carcass lock and / or engage in one or more positions of the plug-in area.

For improved guidance when operating the connector, a guide means may be provided, such as at least one in the body, in particular end face, arranged hole. The latching / locking can be arranged in or on the guide means.

In the body plug-in portion or in the Armsteckabschnitt a parallel to the insertion-oriented slot is arranged, in which the pivot axis of the key arm is arranged so as to rotate and slide so that the pivot axis along the mating area, in particular linear, is movable. The plug-in area can be limited by sliding the pivot axis in the slot in the longitudinal direction. When the joint is actuated, it is possible to provide a joint latching / locking mechanism with which the joint engages / locks in at least one pivoting position. If two joints are provided, the combination of the hinge features with the slidable arm / body may include features of a rotary push or plate hinge. There may also be provided a latching / locking of the key elements on the key arms.

It may be expedient if at least one recess is arranged in at least one key arm, in which the body plug portion of the key body can be arranged, in particular can be arranged so as to be movable in a sliding manner. The body is placed in the arm by inserting the body in the recess.

A preferred embodiment of the universal key described here provides that several key elements are arranged on each key arm at the end. It can be provided a rotating element, which is arranged on at least one key arm end, and which comprises a plurality of key elements, wherein the selection of a key element to be actuated by rotation of the rotary element takes place. The rotation element can be rotatable about a rotation axis, which is preferably arranged parallel to the pivot axis of that bowl element on which the rotation element is rotatably mounted. By virtue of this parallel arrangement, the key can be easily actuated in an intuitive manner with only one hand, since all rotational and / or pivoting movements of moving key components (arms and rotation elements) take place in parallel planes.

Alternatively it can be provided that the axis of rotation of the rotary element of a wrench arm (geometrically) runs perpendicular to the orientation of the pivot axis of the wrench arm. If the orientation of the axes of rotation and the pivot axes have a mutually perpendicular course, the key becomes more compact insofar as the rotation elements are rotatable in a different plane than the key arms. An advantage of this configuration is that, in particular in a U-shaped key arm configuration, a rotation of a rotation element on one arm is not limited by the other rotation element on the other arm. In addition, depending on the configuration of the rotation element, the key arms can be positioned more compactly in a mutually adjacent arrangement.

The rotation element may each comprise two, three or four key elements. If the rotary element in each case comprises 2 key elements, these can be arranged opposite to one another, ie at an angle (distance) of 180 ° relative to the axis of rotation of the rotary element. If three key elements are provided on the rotary element, they can be arranged at an angle (distance) of 120 °. If 4 key elements are arranged on each rotation element, it may be arranged at an angle (distance) of 90 °. If n key elements are arranged on each rotation element, it may be arranged at an angle (distance) of 360 ° / n. There may also be an uneven (angular) distribution of the key elements on the rotating element. The arrangement of the rotation element may include features of a known tool turret. It may be a rotational latching and / or -Arretierung be provided by which the turret element engages in a working position for each key element, so that the key element is easier to handle. The locking can take place in the one or more angular positions of the rotation element (with 2 key elements per rotation element: 180 ° and 360 °, with 3 key elements per rotation element: 120 °, 240 °, 360 °, with 4 key elements per rotation element: 90 °, 180 °) °, 270 °, 360 °, etc.) so that one (selected by the user) Key element forms a substantially linear continuation of the key arm.

At least one, preferably each, of the key elements may comprise: a polygon socket, an external polygon, a beard, a spanner, and / or a tool holder. The polygon socket can be formed as an internal mallet, square socket or hexagon socket. The outer polygon can be formed as an external striking, external square or external hexagon. The beard can be formed as a double beard. The receptacle for a tool element may comprise a receptacle for a tool bit. There may be provided a key element with a stepwise taper, each step comprising an outer polygon or a polygon socket.

According to one embodiment of the key, a key element may be provided which comprises a first polygon socket and a second polygon socket. The key element may have a substantially cylindrical key element body, wherein the two inner polygonal openings are arranged on one of the end faces of the key element. The first polygon socket and the second polygon socket of this at least one key element each have a different key dimension. For example, the first inner polygon can have a greater degree than the second polygon, provided that both of these inner polygons are each formed as triangular, square or hexagonal. For example, if the first polygon socket is an internal detacher, and the second polygon socket is an internal quadrant, then another key dimension of the internal polygon is per se given. The first inner polygon and the second polygon are within the at least one key element offset from each other and / or arranged rotated. For example, it puts hot that the geometric center of the first and second inner polygon do not occupy the same position within the key element. Twisted to one another means, for example, that although the first and second inner polygon have a common geometric center, but that the orientation of the first polygon from the orientation of the second polygon socket around a Angle deviates. It can also be provided a combination of offset or rotation of the nested inner multi-edge.

In the key element described here with two combined inner polygons, for example, a combination of an internal dancer (first polygon socket) and a square socket (second polygon socket) can be provided. A section of one side of the inner striker forms one side of the inner square. In the opposite side of this common three- and square-sided is a recess, which forms the opposite tip of the inner striker.

Alternatively, a combination of two mutually offset by an angle arranged offset triangles may be provided. The second (smaller) internal dancer is arranged in the first (larger) triangular and the tips of both combined triangular edges are arranged rotated through the angle of about 60 ° to each other. Thus, opposite one side of the first triangle, there is a peak of the second triangle. First and second triangles have different degrees, so that with the combined key element two locks with different key size can be actuated. Changing a rotary element for actuating different locks is not necessary since different locks can be actuated with this combined key element.

According to a further variant, two inside fours and mutually rotated by an angle arranged inner square edge are provided in the combined key element. The angle by which the first inner square is arranged rotated relative to the second inner square is about 45 °. The first inner square has a larger key size than the second, arranged by 45 ° twisted square.

In particular in the region of the first joint, at least one additional key element can be arranged, wherein the additional key element arranged on the key arm is simplified by pivoting at least one key arm becomes operable. The auxiliary key element may comprise a radiator vent key element.

The first key arm may have a first key arm contour in the region of the (first) joint, and the second key arm may have a second key arm contour in the region of the (second) joint. The first key arm contour and the second key arm contour may be complementary or nearly complementary to each other. The contours may comprise recesses into which the body, in particular the body plug section, can be moved in, when the respective key arm is pivoted relative to the body. Incidentally, the contours may include form elements in which, in particular, the pivot axis receptacles are arranged. The contours of the cabinet key can be made more compact, which improves its handling, especially in tight spaces in the range of the shutter to be operated. By Schlüsselarmkonturen can also be achieved that at least areas of the body are then covered by the contours when the key arms are aligned, ie non-pivoted, arranged to each other. The first Schlüsselarmkontur and the second Schlüsselarmkontur can, in particular form-fitting, adjacent to each other and / or engageable with each other, whereby in flush arrangement of the key arms of the key body is completely or almost completely in the key arm or in the key arms can be arranged. As a result, impurities and an associated impairment of the mechanics in the area of the key body and the joints are avoided, the body is shielded in a sense keyed position aligned in a sense by the contoured, interlocking key arms and the respective plug sections respectively sealed, whereby contamination of the joints in particular can be avoided , The key arms engage in aligned arrangement optionally at least partially into each other, whereby the key is compact manufacturable, and thereby the handling of the cabinet key is improved in so far as the key is stable. In addition, by the interlocking contours of the key arms a haptic and / or achieved visual enhancement and improved ergonomics of the cabinet key.

The first key arm and / or the second key arm may differ from the key body in terms of material or color or surface finish. The first key arm may differ from the second key arm in terms of material or color or in terms of labeling or surface finish. This provides an intuitive understanding of the pivoting functions of the key arms, making the key easier to handle. Instructions for swinging the key arms are not required.

There may also be provided a fastening element, in particular a clip, with which the switch cabinet key can be fastened in a pocket or in a suitcase. In addition, an individualization region, in particular arranged on one of the key arms, can be provided, in which a marking or inscription, for example a label, can be arranged.

Preferably, at least one additional tool may be provided which, in particular via a fixing means, is arranged captively on the key or switch cabinet key. It can also be provided several additional tools. The additional tool can be, for example, a tool bit which is equipped with at least one blade, preferably with a plurality of blades, for corresponding screw heads. Preferably, a double bit or multiple bit can be provided. The blades may be those for slotted screws and / or Phillips screws and / or Torx screws and / or Allen screws and / or other types of screws. The fixing agent can be formed as a chain or as a band or as a rope or as a wire or otherwise flexible. The fixing means may comprise a closure so that the fixing means can be opened / closed, whereby the additional tool can be removed from the fixing means or at least one further additional tool can be arranged on the fixing agent. The additional tool can be used in a key head, insofar as the fixing should allow sufficient mobility of the additional tool. At the same time is achieved by the fixing means that key and additional tool (s) are permanently connected to each other.

The handling of the key described above is achieved - in particular with regard to national or regional standards - by a kit for mounting a key or cabinet key according to claim 21. Accordingly, a key described here respectively control cabinet key is provided, as well as a set of at least two mountable and / or replaceable key elements.

DETAILED DESCRIPTION OF EMBODIMENTS

A perspective side view of a key formed as a cabinet key 1 can the Fig. 1A be removed. The cabinet key 1 comprises two key arms 2a, 2b, which are arranged on a key body 3. At the end 22 of each key arm 2a, 2b key elements 5 are arranged. The key elements 5 are each arranged on a rotary element 4a, 4b. The rotary member 4a (4b) is rotatably disposed on the key arm 2a (2b).

With the key elements 5 closure elements can be opened and / or closed, which are encountered in particular at control cabinets. The key elements 5 may also be adapted to actuate valves and / or per se known locking respectively unlocking mechanisms.

Between the key arm 2a and the body 3, a first joint 6a is arranged and between the key arm 2b and the body 3 is a second joint 6b. The key arm 2 a is pivotable with the joint 6 a about a first pivot axis 7 a relative to the body 3. The key arm 2b is pivotable relative to the body 3 about a second pivot axis 7b.

Of the Fig. 1A can be seen that the key arms 2a and 2b are arranged in alignment with each other, ie, the orientation of the axes of symmetry of the key arms is collinear or almost collinear. The key arms 2a, 2b are therefore not pivoted relative to the body 3, respectively pivoted. Relative to the orientation of the flight respectively the common symmetry direction (x, see Fig. 2B ) according to Fig. 1A arranged key arms 2a, 2b, the joints 6a and 6b are arranged one behind the other. By sequencing of the joints 6a, 6b comprises the in Fig. 1 A shown switch cabinet key 1 features a double joint (6a, 6b).

The directions of the pivot axes 7a and 7b are perpendicular to each other. According to Fig. 2B the pivot axis 7a extends in the z-direction, which is perpendicular to the x-direction, and the pivot axis 7b extends in the y-direction, which is perpendicular to the x-direction and to the y-direction. The key arm 2a can thus be pivoted in a plane which is perpendicular to the plane in which the key arm 2b can be pivoted.

Of the Fig. 1B may be another view of the key 1 according to Fig. 1A be removed. According to the in Fig. 1 B shown view reveals at least one of the key arms, here key arm 2b, an individualization area 20 in which approximately a lettering 21 or a logo can be provided. Due to the individualization area 20, the key 1 can be individualized insofar as, for example, manufacturer instructions or special instructions for use can be taken into account. On the sides of the key arms 2a, 2b, where no customization area 20 is provided, such as in Figures 1A and 1B shown, on key arm 2a, at least one profiling 32, may be provided, whereby the key 1 is easier to grip when operating in the hand and less slipping, which further improves the handling. The profiling 32 can be arranged directly in the material of the key arms 2a, 2b or in a key arm sheath which can be provided on one or both key arms (2a, 2b).

Fig. 1C shows a variant of the key 1 according to the Figures 1A and 1B in which an additional tool 33 is provided which can be arranged in an additional tool receptacle arranged in at least one key element 5. The additional tool 33 can, as in Fig. 1C shown as a double bit with two screwdriver blades 34 may be formed. It may alternatively be formed as a single bit or as a multiple bit. It can also be provided a bit set.

The additional tool 33 is, as shown in Fig. 3C, captively attached to the control cabinet key 1 via a fixing means 35. The fixing means 35 is formed as a band or chain 36. The chain 36 is arranged in a first fixing means receptacle 37 and in a second fixing means receptacle 38. The first Fixiermittelaufnahme is formed as a through hole in one of the key arms (2a, 2b) through which the chain 36 is guided. The second Fixiermittelaufnahme 38 is also formed as a hole in the auxiliary tool 33. The chain 36 passes through the two holes 37 and 38, whereby two things is achieved: First, the additional tool 33 with the necessary flexibility in an additional tool holder, such as a corresponding key element 5, are arranged, on the other hand, the additional tool 33 is captive with the Switch cabinet key 1 connected. The additional tool 33 can not be lost accordingly. If necessary, additional auxiliary tools, for example additional bits, can be arranged on the fixing means 35, so that, for example, a first additional tool 33 can be exchanged for a second additional tool, the first and the second additional tools being arranged captively on the key 1. The chain can include a closure (not shown) so that additional tools can be attached to it.

The components of a cabinet key described here, in particular according to the Figures 1A / 1B , can the Fig. 2A which shows an exploded view of the key 1. The two revolver-like rotation elements 4a, 4b are respectively arranged at the end 22 of the key arms 2a and 2b. The rotation elements 4a, 4b are in the key 1 as shown in FIG Fig. 2A rotatably mounted in receptacles 26 of the key arms 2a, 2b. The receptacles 26 are located in key arm portions 30 which define a receiving pocket 31 at least on two opposite sides of the arm 2a, 2b. For the rotatable arrangement of the rotary elements 4a, 4b, a pin 27 is provided which sits in the receptacle 26 and in a central bore 28 of each rotary element 4a, 4b. By loosening the pin 27, the rotation element 4a, 4b according to a preferred embodiment of the cabinet key 1 if necessary against another rotation element, such as a set of several Rotation elements to be replaced. The rotation of the rotary element 4a, 4b takes place around the axis of rotation defined by the pin 27. The rotation axis of the rotation member 4a is perpendicular to the rotation axis of the rotation member 4b. Both axes of rotation of the rotary elements are perpendicular to the symmetry x, which may be determined for example by the symmetry of the key body 3 or by the insertion direction of the key arms 2a, 2b.

According to the (explosion) representation after Fig. 2A are the key arms 2a, 2b on the body 3 slidably and rotatably arranged. A body plug-in section 11 is located on the body 3 at each end. The body plug-in section 11 is arranged in the arm plug section 10, wherein each key arm 2 a, 2 b comprises an arm plug section 10. In the body 3, two elongated holes 12 are arranged, wherein the elongated extent of the elongated holes 12 parallel to each other and parallel to the symmetry x. Through the opening of each slot 12 engages a hinge pin 29 which is fastened in a receptacle 18. The orientation of the hinge pin 29 of the hinge 6a is orthogonal to the orientation of the hinge pin 29 of the hinge 6b. The orientation of the hinge pin 29 of the hinge 6a is parallel to the orientation of the pin 27 of the rotary member 4a disposed on the key arm 2a. The orientation of the hinge pin 29 of the hinge 6b is parallel to the orientation of the pin 27 of the rotary member 4b disposed on the key arm 2b. The hinge pins 29 form the pivot axes 7a and 7b of the joints 6a and 6b.

The key arms 2 a and 2 b each have a recess 14 at the end, into which a body plug-in portion 11 of the body 3 can be inserted at least in sections. The recess 14 on the key arm 2a is bounded by a contour 15a, the recess 14 on the key arm 2b is bounded by the contour 15b. On each key arm 2 a, 2 b, form elements 17 are arranged on opposite sides in the region of the recess 14. The mold elements 17 each comprise a receptacle 18 for the pins 27, which form the pivot axes 7a, 7b.

The FIGS. 2A and 2 B it can be seen that each key arm (2a, 2b) comprises two key arm sections 30, and two form elements 17. The mold elements 17 are located on the sides of the key arm 2 a, 2 b, which are formed by the Schlüsselarmabschnitte 30. The position of the Schlüsselarmabschnitte 30 (form elements 17) of the key arm 2a is rotated relative to the key arm 2b by 90 ° about the axis of symmetry x.

Fig. 2B shows a different view of the exploded view of the cabinet key 1 according to Fig. 2A , The key arm 2b includes an individualization area 20 which carries a label 21. The inscription 21 can be embossed in the area 20. It can also emerge from the area 20. Of the Fig. 2B For example, the magnets 39 can be removed by which a magnetic force is caused during the latching of the arms / joints, which, inter alia, comprises a force component acting in the x-direction. The magnets 39 are part of the latch 19. The latching 19 with the magnets 39 causes the key arms 2a, 2b are locked to the body 3, in particular when key arm (2a, 2b) and the body 3 are arranged in alignment with each other and not apart were pushed. There may be provided a further latching / locking in the 90 ° position of the key arm. Of the Fig. 2B can also be the pivot axes 7a, 7b are removed, which are arranged in the receptacles 18.

A switch cabinet key 1 described here in which the first key arm 2 a is pivoted about the first pivot axis 7 a relative to the body 3 and to the second key arm 2 b by about 90 °, ie at right angles or at right angles, can Fig. 3A be removed. By pivoting the first key arm 2a with the hinge 6a, the second key arm 2b forms a kind of lever, so that the control cabinet key 1 is better operable and easier to handle. The total length of the key 1 is reduced by the pivoting of the first key arm 2a, whereby the key 1 is also used there, where - for construction reasons - comparatively little space for attaching the key 1 to a closure element is available.

Of the Fig. 3A can also be seen that the additional key element 8, which is arranged laterally on the key arm 2a, is easier to handle. The key arm 2b forms an actuating aid or a lever when operating the auxiliary key element 8 and the dimension of the key 1 is compared to the dimension in the Schlüsselarmstellung according to the FIGS. 1A to 1C reduced in at least one direction. If the auxiliary key element 8 comprises a radiator vent valve key, this can be better handled in the close vicinity of the radiator vent valve. A lateral view of a cabinet key 1, in which the key arm 2 b is pivoted relative to the body 3 and relative to the key arm 2 a, the Fig. 3B be removed. A synopsis of FIGS. 3A and 3B makes it clear that depending on which (additional) key element (5, 8) is to be used, a pivoting of the first key arm 2a or a pivoting of the second key arm 2b may be expedient.

The picture according to Fig. 4A shows a cabinet key 1, in which both key arms 2 a, 2 b are pivoted relative to the body 3. Accordingly, according to Fig. 4A both the first key arm 2a and the second key arm 2b are pivoted relative to the body 3, in each case by approximately 90 °. The directions of the pivot axis 7a and the pivot axis 7b are perpendicular to each other or almost perpendicular. Of the Fig. 4A It can be seen that the key arm 2a relative to the key 2b has a spatial offset (40) perpendicular to the direction of the original longitudinal extent (x) of the universal key 1. The offset 40 an additional lever is formed, through which a selection of the key elements is better actuated. By pivoting the key arms 2a and 2b about the mutually perpendicular pivot axes 7a and 7b, the key 1 becomes considerably more compact and thus even more usable and manageable in tight environments.

The view according to Fig. 4A further clarifies the operation of the joints 6a and / or 6b. The joint 2 a, 2 b comprises a plug-in region 9. The key arm 2 a, 2 b and the body 3 are arranged along the plug-in region 9 so as to be movable toward each other along an insertion path 23. As in the FIGS. 2A / 2 B shown can be a releasable locking or latching (about with a latching element 19, with magnets 39, see Fig. 2A / 2B ) of the key arms 2a, 2b may be provided on the body 3. When sliding the key arm 2a, 2b along the plug-in route 23 in the plug-in area 9, the latching / locking (19) is released. If the latch 19 includes magnets 39, they are pulled apart against the effect of the magnetic attraction force when releasing the latch 19. The engagement is assisted by the force of attraction of the two magnets 39, so that the engaged components (key arm 2a, 2b and body 3) abut each other as a result of the magnetic interaction with force. As an alternative to latching / locking by means of magnetic action, latching / locking can be provided by means of mechanical means, for example by means of a ball 41 which can be latched in a recess or a cam which acts in a similar manner in conjunction with a groove 42. In the case of a mechanical latching / locking, a positive connection between be done the locking / locking means.

The sliding movement of the key arms 2a, 2b when releasing the latching 19 is linear, approximately along the symmetry axis x of the body 3 or the key 1 (see FIGS. 1A to C and / or FIGS. 2A and 2B ). The key arm 2a (FIG. 2b) arranged on the joint 6a (FIG. 6b) comprises an arm plug section 10 at each end. The key carcass 3 comprises a carcass plug section 11. The plug socket section 10 and the carcass plug section 11 are arranged so as to be slidable so that the carcass 3 fits into the carcass Key arm 2 a, 2 b along the plug-in portion 9 in and / or heraussteckbar. The body plug-in portion 11 is arranged in a recess 14 of the key arm 2a, 2b. The pivot axis 7a, 7b is disposed in a slot 12, whereby the sliding movement of the pivot axis 7a, 7b (and thus also the key arms 2a, 2b) is limited in the plug-in area 9 (plug-in distance 23).

For pivoting the key arm 2 a, 2 b, the key arm 2 a, 2 b is first to slide linearly in the plug-in region 9 along the symmetry direction (x) of the body 3. In this case, the pivot axis 7a, 7b is moved in the slot 12. The body plug portion 11 is thereby moved out of the arm insertion portion 10 at least partially. The key arm 2a, 2b can then be pivoted about the pivot axis 7a, 7b in a first direction or in a second, to the first substantially opposite, direction. At a pivoting angle of about 90 °, the edge 13 of the arm plug portion 10 abuts against the body 3, whereby the pivoting movement (in particular the pivoting angle) is limited.

Of the Fig. 4A It can also be seen that each key arm 2a, 2b has a contour 15a, 15b in the region of the associated joint 6a, 6b. With aligned arrangement of the key arms 2a, 2b (see u. Fig. 1A ) engage the contours 15a and 15b at least partially (complementary) into each other. Each contour 15a, 15b comprises two opposite recesses 16, in which the body 3 comes in upon pivoting of a key arm 2a, 2b. Furthermore, each contour 15a, 15b comprises two opposing mold elements 17, which form a receptacle 18 of the pivot axis 7a, 7b. When aligned and locked arrangement of the key arms 2a, 2b, the mold elements 17 may be at least partially disposed in the recesses 16 of the contours 15a, 15b. By pushing out the key arms 2a, 2b along the plug-in route 23, a gap 24 is created between the contours 15a, 15b.

It can be provided that the key body 3 has a different color or a different color or gray scale than the key arms 2a, 2b. It can also be provided that the key arm 2 a differs color and / or design from the key arm 2 b. This allows the user to intuitively perceive the function of the joints 6a, 6b. Preferably, key arms 2a, 2b and key body 3 may be made of different materials, such as plastic and / or metal, such as a zinc die-casting.

The rotation elements 4a, 4b with the key elements 5 may preferably be formed of metal.

As in Fig. 4B illustrated, at least one key arm 2a, 2b, an indi-vidualisierungsbereich 20 may be provided in which a label or a label 21 is arranged. The inscription 21 may include an embossing, so that the inscribed area can be haptically distinguished from its surroundings. The Fig. 4B shows a cabinet key 1, in which the joints (the double joint) have been operated (has been), that first key arm 2a and second key 2b were respectively pivoted relative to the body 3, and that between the first key arm and the second key arm offset 40 has arisen. The key 1 according to Fig. 4B includes an additional tool 33 which is secured with a chain 36 on the second key 2b.

One or more markings 25 can also be arranged on the key elements 5, which allow the user of the universal key 1 to be aware of which variant of the key elements 5 is in a use position by means of rotation elements 4a, 4b.

A variant of the key 1 can the Fig. 5 be removed. Fig. 5 shows a schematic view, has been omitted to simplify the presentation on the reproduction of rotation elements and key elements. In this respect, the figure of the body 3 of the key 1 can be removed and arranged on the body 3 key arms 2a and 2b. The key arms 2a, 2b are according to Fig. 5 shown on the key in a pivoted position, wherein the key arms 2a, 2b are arranged parallel to each other or nearly parallel. Each of the key arms 2a, 2b according to Fig. 5 was pivoted relative to the linear arrangement by a pivot angle of about 90 °, wherein the in Fig. 5 shown pivoting direction of the one arm 2a is opposite to that of the other arm 2b (a linear arrangement of a key variant is exemplified in Fig. 1A ) Shown. Relative to the key arm 2b (2a) was according to Fig. 5 the key arm 2a (2b) by a total Verschwenkwinkelbetrag of about 180 ° swiveled. Key arms 2a, 2b and body 3 thus form in the position according to Fig. 5 a U-shaped key configuration. This is achieved by the pivot axes 7a, 7b are spaced from each other and parallel to each other or almost parallel. The pivot axes 7a, 7b therefore have identical orientations and are arranged on the body 3 of the key 1 at the end. The key arms 2a, 2b are also according to Fig. 5 arranged side by side, so that the universal key 1 is compact and therefore easier to handle.

To the according to Fig. 5 free ends of the key arms 2a, 2b, ie at those ends which are opposite to the ends of the arms 2a, 2b connected to the body 3, are receptacles 26 for to be arranged therein according to Fig. 5 however, not shown, to recognize rotation elements. According to Fig. 5 the receptacles 26 extend parallel to the pivot axes 7a, 7b. According to one in the FIGS. 1 to 6 not shown variant, the receptacles for the rotation elements along one or two lines extending perpendicular to the pivot axes 7a, 7b.
