Description

The invention relates to a control cabinet key having a central base body, from which protrude a plurality of key arms radially, at the outer ends of tool heads are formed, wherein at least one tool head is designed as a socket wrench, wherein the tool head defines a receiving space, the first, drive profile (key area) includes, which is adapted to actuate a complementarily shaped clasp, a lock, possibly also a nut or the like. Often the drive profile comprises an enclosed receiving space. The first drive profile thereby extends in a primary key blade plane of the respective key arm, which in turn extends transversely to a respective key arm longitudinal axis, with the key arm longitudinal axes of all key arms in the center of the body cross, thus the main body forms the crossing point of the key arm longitudinal axes. Furthermore, a second drive profile may be formed in the tool head, which is different from the first drive profile.

State of the art

Such a cabinet key is eg from the EP 1 422 365 B1 the applicant known. This control cabinet key has a central base body with four radially projecting key arms. At the outer ends of the key arms tool heads are formed, which have different head shapes for the operation of different cabinet locks.

Similar tools or switch key are known from the WO 2011/101 397 A1 . EP 2 781 309 A2 and US 838 109 A ,

One or more tool heads of such a cabinet key are formed as a socket wrench with an inner receiving space which is circumferentially enclosed by a drive profile or a key surface which is adapted to actuate a complementarily shaped clasp, a lock, a cabinet, a door or the like. The key area may e.g. be designed as a triangle, a square, but also a hexagon. The first key blade plane extends transversely to the longitudinal axis of a key arm through this receiving space, which first key blade plane may extend at any location across the receiving space along its entire longitudinal extension direction.

To increase the application of such a cabinet key is already known to provide a plug-in tool and / or an adapter with a captive on this. This allows a tool head to be used directly. Alternatively, the male tool is inserted into the tool head or attached to a tool head via the adapter piece and threaded with the male tool rather than with the tool head itself.

Disadvantages of the prior art

In the development of the invention, it has been found that the drive profiles of the cabinet key only engage under optimal conditions with all surfaces of the respective joining partner, the complementarily formed surfaces of the drive profile and the joining partner thus only lie flat against each other under optimal conditions. However, inaccuracies in production, tolerance deviations, soiling and wear inevitably cause the surfaces do not rest against each other optimally flat, but often the joining partners interlock only with the edges or corners. This is referred to in the context of the invention as "edge contact" or "corner contact". However, this edge contact reduces the torques to be transmitted or loads the joining surfaces considerably, leading to fatigue and breakage of the tools.

Furthermore, the market is increasingly demanding that a control cabinet key covers an even broader spectrum of possible uses, that is, it can be used even more diversely. This runs contrary to the general desire that the size of such a cabinet key can not be increased arbitrarily, so this should only have a certain size so that it can be used in tight situations and is easy to carry, so has no increased weight and easy in the bag is stuck.

Task / technical problem

Based on this prior art, the present invention seeks to avoid these disadvantages, at least in part and in particular develop a panel called bowl, so that material fatigue avoided as possible and thus have the control cabinet key and the joining partners have a longer life.

invention

According to the invention, this object is already achieved by the features of claim 1 and advantageous developments are given in the dependent claims.

The invention makes use of the fact that the corners of the mating interlocking surfaces are particularly important. By the angular offset of the drive profiles or of their joining surfaces to each other ensures that the corners are available for the complementary engagement of the joining surfaces and their edges. In this respect, the partial design of the second drive profile in the primary key blade level is already sufficient for the realization of the edge engagement. The full engagement is realized when the joining partner to be actuated is fully inserted into the second key blade level. In addition, the invention makes use of the combination of different types of offset of a second drive profile in relation to a first drive profile. Axis offset means that the center axis of the second drive profile is offset in a key armature plane in relation to the center axis of the first drive profile such that all corners of the second drive profile are already available in the first key armature plane for at least one edge engagement. Rotationally offset means that two drive profiles are arranged coaxially in a key-arm plane, but the second drive profile is arranged at a different angle relative to the first drive profile. Preferably, the profiles are offset at an angle of 45 to 60 degrees, preferably 45 and 60 to each other. And linear offset means that the second drive profile is arranged in relation to the first drive profile on a different plane along the key arm longitudinal axis. The invention combines these types of offset in all possible combinations, if possible several times in each key arm.

The key arm longitudinal axis extends centrally along each key arm, and the primary key arm plane is the tool level directly accessible from the outside of a key head, and extends from the outer surface or opening of a tool head to about 6 mm into the respective tool head and sometimes enters there a second Schlüsselarmwerkzeuetee, which again about a depth of 3-5 mm.

In the most abstract embodiment, this object is achieved with a control cabinet key of the type mentioned in that the second drive profile is formed proximally linear offset to the main body in a secondary Schlüsselarmwerkzeu level, that the second drive profile is rotationally offset formed to the first drive profile and that this second drive profile also is already partially formed, at least with the corners in the primary Schlüsselarmwerkzeugee, so also extends into the first Schlüsselarmwerkzeugee. The corners of the second drive profile in the primary key blade plane thus form pre-engagement surfaces according to the invention, with which actuation of the lock, tool or the like actuated by the second drive profile can be realized in most applications by the edge engagement. Only for very old and worn locks with worn flanks, the key arm must be fully inserted until the second drive profile fully engages. This reduction to the edge engagement represents an essential aspect and an essential aspect of the invention.

Even better service life and wider applications can be realized by another, ie third drive profile is formed with an axial offset to the first drive profile in the primary Schlüsselarmwerkzeugee, and that this third drive profile also rotatably offset with an angular offset at an angle to the first drive profile in the primary key blade level is formed.

It has proved to be expedient in that the second drive profile is only partially formed or pronounced in the first Schlüsselarmwerkzeugee and in an underlying second or secondary Schlüsselarmwerkzeugebene, which is thus formed in the direction of the main body in the key, then only the full drive profile is formed. This partial design of the second drive profile in the primary key blade stage thus already provides a "Vorgrifffläche" for transmitting smaller torques of the second drive profile, the full torque but only when inserted into the location below the Schlüsselarmwerkzeugebene second Schlüsselarmwerkzeugebene.

For the angular offset, an angle between 0 and 45 degrees rotation has been found to be useful, particularly preferred results and stable wall thicknesses of the key arm were achieved at 45 degrees offset.

The drive profiles preferably have different geometrical configurations, but may also have the drive profiles in different sizes. This design offers the advantage, with surprisingly simple means, that a plurality of different key surfaces can be formed on a tool key plane in a tool head, ie only minimal changes in the tools are required in a minimal space to increase the functionality. This is particularly advantageous over other configurations with multiple tools on a control cabinet key, because no further keys, adapters or the like are provided which would make the cabinet key heavier or more complex.

The first drive profile may e.g. triangular be formed and the second drive profile quadrangular, the square - second - drive profile is arranged off-center with respect to the center of the triangular key surface off-axis. This has the advantage that the square key surface is almost completely available for the force engagement, although it is partially interrupted by the first, triangular key area.

In addition to a triangular and a square key surface, it is of course also possible to provide other geometric combinations of the key surfaces or to connect with each other.

Even further, the application possibilities for a given size of the control cabinet key can be increased by the fact that different drive profiles are formed in different planes in the longitudinal extension direction of a key arm or tool head, ie a further drive profile in a further inwardly linearly offset from the first key arm workpiece level in the direction of the main body - Key armature level. For example, it is possible for a first, central drive profile and a second drive profile, offset from the first drive profile, to both be formed in the first key-arm plane, and a third drive profile to be formed in a second key-arm plane, inwardly offset to the main body, e.g. with a smaller hexagon, which begins only in a insertion depth of 9 to 10 mm.

To increase the torque applied by the user even in confined spaces, it has become particularly useful with smaller cabinet keys, e.g. with a length of 65 mm from the outer end of a first key arm to the outer end of the opposite key arm proved to be expedient that at least one of the key arms has an outside key surface for engagement of an open-end wrench, particularly preferably designed as a hexagon. Preferably, each of the key arms has such key surfaces, wherein in a further development differently sized key surfaces may be provided on different arms or on both sides of the center extending outwardly on one side a first key surface and on the opposite side of the key arm, a second other key surface. These wrench surfaces are in particular designed for cooperation with an open-end wrench or open-end wrenches of different key sizes.

Preferably, a key arm as a tool includes a double bit. Such a double bit comprises a along the Schlüsselarmlängsachse and this with its cylindrical surface enclosing cylindrical base body, extending from the diametrically opposite radially outwardly two beards. Each beard is basically formed as a parallelepiped-shaped body which comprises a distal or frontal Barteinsteckfläche and two spaced from the cylindrical body radially outwardly and to each other by the width of the Einsteckfläche beard flank extending from the cylindrical surface of the up to a radially outer beard outer surface extends, which connect at the - rear - proximal ends in the lateral surface of the key arm or connect to this.

The stability against wear or the service life is improved in such a double bit by the fact that the double bit has an inside collar or an inside stabilization flange at the transition to the lack of surface of the key arm, which extend transversely to the key arm longitudinal axis.

In fact, in the development of the invention, it has also been found that this inside collar substantially reduces the notch effect, especially at the bottom of the sides of the double bar, so that with such a double bit about 30-50% higher torques than with a double bit without such an inside Federation can be transferred.

A further improvement of the service life can be achieved in that the diametrically radial, projecting from the central cylindrical surface beards in the area of the lateral surface are wider than at the beard outer surfaces or from their radially outer beard surfaces to the cylindrical lateral surface, ie from the outside widening inwardly, so as to reduce the notch effect at the transition of the beards in the central, cylindrical outer surface of the double barb, or to form the beards more stable and thus compensate for any occurring between the joining partners game, so if a beard not flat correct in the complementary recess of the joining partner / castle sits. Here, too, the inventive concept of edge engagement is thus made use of.

Be particularly useful in the development of the invention, a conical broadening of the beards from outside to inside out, because this realizes a harmonious transition and wear phenomena on the castle or the joining partners long-term compensated or a Variety of fits realized even with signs of wear.

The particularly preferred embodiment provides that each beard on the beard base, ie radially inside, immediately following the cylindrical base body, in the range of 8 to 12 percent, preferably 10 percent wider than on the radially outer outer edge of the Barts. This is done e.g. by a beard flank inclined slightly to the central axis, that is, e.g. with the central axis forms an angle between 5 to 8 degrees, preferably 6 degrees. A uniform increase in the width of the beard to the base of the beard is expedient for the eventual occurrence of play, e.g. due to aging between the joining partners to compensate harmoniously.

Particularly long service life or a particularly long life and stability of a double bart is achieved by combining the two new developments, ie the radially extending from outside to inside beards, at their distal ends to go towards the base body in a stabilizing flange or such Stabilization on flange.

For the purposes of the invention, the radially outer end of a key arm is proximal and distal to an orientation to the center of the main body.

In the preferred embodiment, 3 of the total of 4 key arms comprise further drive profiles formed in a second keyed armature plane relative to the first key armature level of the respective key arm. In this way, numerous combinations are possible. Thus, e.g. in the first Schlüsselarmwerkzeugee two angularly offset from one another arranged square profiles, of which one extends into the second Schlüsselarmwerkzeugee or is completely formed only in this second Schlüsselarmwerkzeugebene.

Another embodiment of a key arm provides that a triangular drive profile is formed in the first key blade plane and offset therefrom and further rotated in the first key blade plane, another quadrangular drive profile formed in the first key blade plane with only the pre-engagement surfaces and then as a solid profile in the inwardly offset second Schlüsselarmwerkzeugee.

The drive profiles are preferably designed as closed profiles, although this does not necessarily have to be the case.

Conveniently, the key arms are arranged in a plane and thus form a key plane.

The switch cabinet key may also include an adapter piece for receiving a plug-in tool, which is preferably attachable to at least one of the tool heads.

The insertion tool is preferably mounted with a captive, which is particularly preferably designed as a chain. This chain is preferably fastened to a fastening part which is formed laterally on the central base body and between two key arms.

The insertion tool may have a hexagonal peripheral portion which is insertable in a provided on a tool head rotationally fixed.

In addition, the insertion tool may comprise a screwing tool, which preferably has different screw drives at opposite ends.

The main body can also have a square socket, with a vent valve of a radiator to open and close.

A further embodiment provides that a tool head has a pyramid-shaped plug-in element which can be attached to differently sized square openings.

In the preferred embodiment, the cabinet key is made of plastic or die-cast and includes four of the main body radially projecting key arms that define a common key plane.

To operate particularly well, the cabinet key even in confined spaces and a small configuration, if at least one key arm has a key surface for a spanner or the like on the Schlüsselarmaußenseite. This may e.g. by flattening the front and the back of at least one key arm done, but may also include an outside square or hexagon on the key arm.

In order to offer a particularly wide range of applications, the formation of an outside key surface on each key arm is advantageous.

After the drawing there is the switchboard key 1 from a central body 2 with four radially projecting key arms, namely a first key arm 3 with a first tool head 31 formed as a double-beard, a second key arm 4 with a second tool head 41 comprising a square / square double tool, a third key arm 5 with a third tool head 51 comprising a square / triangular double tool and a fourth key arm 6 with a fourth tool head 61 comprising a triangular / triangular double tool, which together form a key cross.

The central body 2 includes two additional tool heads 21 , 22 planned. This is approximately perpendicular to the radial key arms 3 . 4 . 5 and 6 aligned. The key arms 3 . 4 . 5 and 6 define a key master level. On one side of the body 2 is this tool head with a square socket 21 and on the opposite side with a hexagon socket 22 educated.

Laterally on the central body 2 and between two key arms 4 and 5 is a fixing part 8th intended for a captive. The fastening part 8th is as a tab with an opening 81 educated. As a loss, a ring, not shown, closed chain can be provided. On the chain then a plug-in tool and an adapter piece are suspended, which can be preferably designed as a plug-in tool or as a screwing tool in the form of a so-called bits.

It is clearly recognizable in the 3 , which is a longitudinal section through the cabinet key 1 represents that the second key arm 4 , the third key arm 5 and the fourth key arm 6 In any case, always comprise two drive profiles, of which the second drive profile each proximal linear offset to the main body 2 is formed in a respective secondary key arm mold level and the corners thereof also extend into the externally directly visible primary key armature plane to form pre-engagement surfaces in respective primary tool planes.

The first tool head 31 is designed as a double bit, which has a cylindrical base body 311 comprises, whose lateral surface encloses the running through the center of the key arm Schlüsselarmlängsachse. Integrally formed on this cylindrical body 311 stand two beards 312 . 313 radially opposite to the outside. At the inside end of the double bar at the transition to the first key arm 3 this is with a circumferential stabilizing flange 314 trained, which the beards 312 . 313 additionally stabilized and the notch effect on the beards 312 . 313 of the cylindrical body 311 considerably reduced.

Figure sequence 9 with individual figures 9A to 9D shows an enlarged detail view of the first tool head 31 with the double bit, ie along the key arm longitudinal axis on the distal end of the first key arm 3 , the details for clarity only for a beard 312 are provided with reference numerals. Every beard 312 . 313 The double bar is formed by a front Barteinsteckfläche 3121 from which are two bearded flanks 3122 . 3123 at a distance back to the stabilizer flange 314 and between the cylindrical base body 311 and a beard outer surface 3124 extend to the formation of cuboid beards 312 . 313 , The stabilization flange 314 is also wider than the cylindrical body 311

The beards 312 . 313 are preferably designed so that the beard flanks 3122 . 3123 from the beard outer surface 3124 towards the cylindrical body 311 widen conically, with this broadening particularly strong in the body 311 increases so that this broadening provides an increased area for edge engagement (see in particular 15 ).

The front view according to 9D and the enlarged front view according to 15 also show a bit recording 315 for a minibit hexagon, in the circular central opening of the cylindrical base body 311 which annularly surrounds the key arm longitudinal axis with its outer lateral surface, is provided proximal to the double bit in a secondary key arm tool surface.

The second tool head 41 is designed as a "square / square". This includes a first square 411 formed first drive profile disposed in the primary, distal key blade level and proximal of this primary key blade level in the secondary key blade level, a second square 412 trained second drive profile. Again, the second square 412 collinear to the first square 411 arranged but smaller than the first square 411 and rotated by about 45 degrees to this about the key arm longitudinal axis. In addition, in this second tool head 41 collinear to the first square 412 and the second square 412 , and a hexagon socket proximal to the latter in a tertiary key arm tool surface 413 provided, which in turn is smaller than the second square 412 and thus enclosed or enclosed by it.

In the enlarged isometric plan view of the second tool head 41 according to 16 is clearly visible that the first triangle 411 in the primary, ie distal key blade plane extending from the distal outer edge to the end of this square key surface is about 6 mm deep, whereas the coaxial, formed to the primary Schlüsselarmwerkzeugfläche second square 412 proximal to the first and rotated by 45 degrees about the key arm longitudinal axis in 3 to 5 mm downstream of the primary key blade plane, but with the four edges or corners of the second square 412 extend into the first key blade level and there form the pre-engagement surfaces according to the invention, but which are provided in this way on each tool head.

The third tool head 51 is designed as a double key head and includes the combination of a triangular and a square drive profile (triangular / square). The larger, triangular drive profile 511 is again collinear in the primary tool key plane to the key arm longitudinal axis of the third key arm 5 arranged .. The smaller, square drive profile 512 on the other hand, is in the secondary key armature plane proximal to the primary and also axially and rotationally offset to the triangular drive profile 511 arranged, which also for the square drive profile 512 a sufficient wall thickness of the key head 51 is provided and that from the leg of the triangular drive profile 511 downwardly projecting area of the square drive profile 512 is provided as additional contact surfaces for the transmission of torque and in particular all corners of the square drive profile 512 are available for the edge intervention. The smaller square drive profile 512 is also about twice as deep in the key arm 5 arranged like the square drive profile 511 but extends from the secondary wrench plane at least with its edges / corners into the primary wrench plane.

Also the fourth tool head 61 is designed as a double key head (triangular / triangular), with a first triangle 611 in the primary, ie distal key blade level, as well as a second triangular 612 , which is proximal to the first triangle 611 and smaller than this is formed. The first triangle 611 and the second triangle 612 are collinearly arranged along the key arm longitudinal axis, but aligned at an angle of approximately 60 ° rotationally offset from each other. Furthermore, the second triangle is 612 about twice as deep as the first triangle 611 and smaller than the first triangle. Again collinear to the first triangle 611 and second triangle 612 extending along the key arm longitudinal axis is a hexagon socket 613 in a tertiary key armature level proximal to the secondary key armature level.

In summary, therefore, each tool head, according to the invention, is formed so that it comprises at least two drive profiles (key heads), one drive profile in each of the distal primary Schlüsselarmwerkzeugebene and a second drive profile in the proximal thereof remote Schlüsselarmwerkzeuetee, the second drive profile in the secondary Schlüsselarmwerkzeugebene each formed smaller than the drive profile in the primary Schlüsselarmwerkzeugee, preferably a key size smaller. The second drive profiles / wrench surfaces preferably extend at least with the edges or corners into the first wrench tool plane and provide there the edge-engagement pre-engagement surfaces according to the invention.

A third or fourth drive profile may also be formed in each tool head, which is then preferably located in a respective tertiary key blade plane proximal to the respective secondary key arm plane in the key arm, and which tertiary key blade plane is again smaller than the respective second drive profile in the respective one secondary key blade level.

Well recognizable is that in each case the front and the back of the key arms 3 . 4 . 5 . 6 the control cabinet key are flattened and thus define a key area for a spanner, so that each key arm in tight spaces and small configuration of the cabinet key of eg 65 or 55 mm total length from a proximal key surface outer edge to the opposite proximal key surface outer edge sufficient force for rotation or closure can muster. The outer surfaces of the key arms 3 . 4 . 5 . 6 Naturally, however, they can also have other external geometrical surfaces to achieve the same effect, as long as this provides a sufficient force application surface for a tool key.

It will be understood by those skilled in the art that the inventive concept of axial displacement of two or more drive profiles along a key arm longitudinal axis in a key arm, wherein the proximal second drive profile at least with the edges / corners from the proximal to the distal Schlüsselarmwerkzeuetee to provide the pre-engagement surfaces for the edge engagement extends, can also be implemented alone, so on a tool that includes only such a tool.

This also applies to the formation according to the invention of the double bar with the proximal stabilizing flange and / or the beard flanks which propagate inwards from the radially outer beard outer surface.

However, the combination of a cabinet key with different key arms and different tool heads is the most preferred embodiment.

It is understood by those skilled in the art that the double bit according to the invention with the stabilizing flange and / or the radially inwardly widening beard edges is not combined with other tool heads on a control cabinet key, but can also be configured as a separate, ie single tool.

This applies equally to the 2-plane model according to the invention with a first drive profile in a distal, primary key blade level and a second drive profile in a secondary key armature level provided proximally thereof, the second drive profile being smaller than the first drive profile and further thereto is rotationally offset. This embodiment may be formed separately from the combination with a double bit or other key arms as a single tool. However, the combination of a cabinet key with a plurality of different tool heads is the most preferred embodiment. In all embodiments, a third drive profile may be further provided in a tertiary key armature level, which in turn is smaller than the second drive profile.

The subject matter of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with one another. All information and features disclosed in the documents - including the abstract - in particular the spatial design shown in the drawings are claimed as essential to the invention, as far as they are new individually or in combination with respect to the prior art.
