Description

The invention relates to a summary of cabinet keys according to the preamble of the independent claims 1 and 2.

Such summaries of control cabinet keys have already become known in many ways. It is for example on the DE 296 17 973 U1 and US 2006/236821 directed. The summaries are used in particular for the operation of locks on control cabinets, but also on shut-off systems of gas, water and electricity supply facilities. Usually, the keys of a summary in particular a square 6 mm and / or a square 8 mm and / or a square 10 mm and / or a triangular 6 mm and / or a triangular 8 mm and / or a triangular 10 mm and / or a Hexagon and / or a crescent and / or a double bit and / or a step-like outer square, for example in the dimple range 6 to 9 mm and / or a double-bit insert on. In the context of the present invention, it is preferred that one or more of the mentioned keys, in particular also all of the mentioned keys combined, be provided on the summary.

It turns the task to provide a convenient to handle summary of cabinet keys.

A possible solution of the problem is initially given in an object in which a first and a second unit are provided by mutually extending at a fixed angle keys, each unit has its own middle part and the units are detachably connected at their middle parts. Thus, in a summary, a plurality of keys can be transported, which are often individually used in such a way summarized, but for a special or even better use by separation of the units in a so far usual unit, with for example four star-shaped keys, are usable. A key of such a separated unit can be easily handled as usual. In principle, it is also possible for each of the units mentioned to be designed preferably in accordance with the further feature concept explained below, namely, rotatable individual keys relative to one another in a predetermined plane. With regard to the separable units, it may also preferably be provided that these units are indeed separable from each other but not completely separable. They can be held together, for example, by means of a connection chain, so that even when handling a key in a separate unit, the other unit can not be lost.

A further possible solution of the problem is given in a summary, in which the keys relative to each other, however, are rotatable only in a respective predetermined plane. Due to the rotatable arrangement of keys more keys in the summary, in principle star-shaped running each other, be provided, as in a conventional handling is considered beneficial. For handling then the other keys can be turned away laterally to the key used, so that the key to be used in a low-handling enabling freedown comes. Nevertheless, the summation in the region of the middle part achieves the necessary strength to be able to apply a moment.

Thus, it is further preferred that, in the connected state, the keys of a first unit extend at least in the projection perpendicular to a plane in which the keys of a first unit extend between two keys of a second unit. The keys can thus be stacked on top of each other but offset in the projection to each other, in particular star-shaped, arranged. The clarity with regard to the total available keys is thus achieved low. In addition, this can also be achieved an overall compact spatial form of the summary.

It is further preferred that the units, as already mentioned, are connected captively. Instead of the said chain connection can also be provided, for example, a hinge connection.

Moreover, it is preferred that the keys extend from a same height band with respect to their or the middle parts associated foot sections. The working heads of the keys are, as in the prior art summaries, each outwardly facing, especially pointing radially outward arranged. Accordingly, the opposite portions of the keys are referred to as foot sections. The arrangement of the foot portions of the more preferably generally linearly extending key in a same height band provides a like disc-like configuration of the summary in a side view. The foot areas, in particular the geometric axes of the individual keys do not have to be arranged exactly in a same plane for this purpose. Such a height band may, for example, extend with respect to the geometrical axes, perpendicular to the mentioned disc alignment, over a few millimeters, for example in the range of 1 to 10 mm. With regard to the multi-unit embodiment, this characterization refers to the assembled state of the units.

In a composition of the multi-unit summary, as indicated, there are also plural center portions for each of the separable units. In this case, it is preferable for a foot section of a key in the connected state of the units to extend in the direction of extension of the key, that is to say in a projection onto the central region in the longitudinal direction of the key, into two middle parts. This can be achieved, for example, in that the key is rooted in the one middle part, the others, however, freely overlaps due to its shaft thickness, for example. Thus, regardless of a possible relatively thin design of a central part to be desired for handling usual shaft thickness can be maintained. In addition, the units in their combined form also appear more organic.

Preferably, it can also be provided that, as viewed from a geometric center axis of the middle part, which runs correspondingly perpendicular to a geometric longitudinal axis of a key, the distance is different up to the desired conventional shaft thickness or the transition to the desired conventional shaft thickness. This can be further used to that on the opposite central part in the radially outer region a corresponding flattening is provided, so that by engaging the key with the shorter - thinned - shaft region, the range with the usual shaft thickness and the transition then actually engages , a predetermined positional alignment of the middle parts to each other and / or one, possibly also additional, rotational blocking can be achieved.

In forming the summary having a plurality of separable units, they are preferably operatively detachable in the assembled form, i. more preferably connected by a no tool insert for separation requiring handling. This particular connection can be achieved for example by magnetic force. But it can be given by a latching, such as a retractable by special pressure locking projection or the like.

In particular with regard to the keys rotatable relative to one another or relative to one another, provision can also be made for the keys to be rotatable in different planes relative to their geometric longitudinal axes. This can be exploited in particular to ensure that keys are separable and removable.

The control cabinet keys may preferably have different lengths. This designates the dimension along its geometric center axis, measured from the center of the central part or measured from a corresponding geometric center of the summary. With regard to such different lengths, it is preferable, and this may in principle apply to all the embodiments described here, that the length of a switchboard key of greater length exceeds the length of a switchboard key of smaller length, in particular the length of an adjacent switchboard key of smaller length, by 10% or more. This is of particular importance with regard to the embodiment in which the control cabinet keys are present at predetermined angles non-rotatably relative to one another. The measure of significantly increasing the length of the cabinet keys in this respect may result in the advantage that without the dissolution of a multi-unit network the use of a longer key is nevertheless possible. This different length can, for example, up to 400%, so that the key switch key greater length four times the length than the switch key smaller length extend.

Such a design is particularly preferred in terms of a cabinet key having a key bit. A lower edge of the key bit, ie the edge of the key bit closest to the center of the summary, is then preferably provided such that an imaginary extension of this peripheral edge transversely to the geometric longitudinal axis of this cabinet key not one, preferably not with the two - one on each side in the circumferential direction - adjacent cabinet keys (smaller length) collided. This key cabinet key can therefore be inserted into a corresponding keyhole, without the keys smaller length prevent this. Further preferred is between this imaginary extension, given in the longitudinal direction of the geometric axes of the key switch key smaller length, and the beginning of a cabinet key smaller length still a certain distance (additional).

Another teaching of the invention, which also has such significance for such keys, relates to the formation of a tool key, in particular a control cabinet key, with a polygonal socket. For this purpose, it is preferably provided that multiple key widths are formed over the depth of the inner polygon. The polygon socket thus tapers in the depth direction, preferably, this taper is step-like. The transition need not be given at right angles corresponding to a step surface, but may also be a cone with a relatively small cone angle, for example. In the depth direction of the narrower wrench size adjoins the taper in the depth direction, which has a practically constant opening width over a corresponding depth, as well as the previous range of larger key width.

Another preferred embodiment of the switch cabinet key described here is also given by the fact that the outer shape of a key corresponds to the inner shape. If a key thus has, for example, an internal tappet, the head of the key in which the internal tappet is formed is correspondingly designed as a triangular. The same applies to other polygonal training. Since such control cabinet keys are sometimes to use in a spatial conditions in which the lighting is not cheap is so alone can be found by keys just the appropriate key.

It is also preferred that the keys are stacked on top of each other on the central part forming a collection axis. In particular, this concerns individual or individualized keys. The middle part is initially separated or separable from the keys. The keys can be summarized about by means of a central hole part on the collecting axis. In a preferred embodiment, the collection axis may consist of two intermeshing axle parts. The axle parts can for example be screwed together. One or both axle parts can also be formed out of a mounting plate growing out. In this case, forms an axle, possibly together with a mounting plate, the middle part.

It is also preferred that a key has a foot-side plate portion having an opening suitable for the passage of the collecting axis. Thus, the keys can be stacked individually in the area of their foot parts and held together by the axis summarized.

Instead of being rotatable relative to each other in different planes, it can also be provided that the keys are rotatably arranged in a same plane relative to one another. In particular, without the overall thickness of the summary becoming too large, this allows a relatively large, relative to the diameter, foot area of the key.

In particular, it is preferred that a key foot forms a sliding block and is received in a backdrop of the central part. So can one Moving the key are readily made, but the required torque transmission at the same time be ensured.

In particular, the middle part can also be annular. If this embodiment is combined with the embodiment that a link is provided in the middle part, this can for example be provided radially outwardly opening in the annular Mitteilteil.

In particular, the middle part can also be composed of two shell parts, each forming a part of the slide track.

It is further preferred that keys of different lengths are formed. In particular, that the working areas of the keys are at different radii. Furthermore, in particular, that a key with a greater length, that is to say the extent in the direction of its longitudinal axis, is adjacent to two further keys of lesser length. In this way, it can be achieved that the key of greater length, the working area of which projects correspondingly further, can also be used without the adjacent keys having to be turned away or, in the case of two individual parts, first having to be separated from one another.

The indicated above and below regions or ranges of values with regard to the disclosure include also all intermediate values, particularly in ¹ / _10th increments of the respective dimension, possibly also dimensionless, so eg. ^1, / _10% etc., on the one hand to limit the said Area boundaries from below and / or above, alternatively or additionally but also with regard to the disclosure of one or more singular values from a respective area.

The embodiment of the Fig. 1 to 8 relates to a summary 1 of cabinet keyboards 2, in the embodiment, as also preferably provided, even with a Doppelbiteinsatz 3. The individual keys 2 are each, see in particular Fig. 4 , connected to a first middle part 4 or a second common middle part 5. In principle, it is also possible to provide further middle parts of this kind with associated control cabinet keys 2. The cabinet key 2 are connected to the middle part 4 and 5, respectively at a fixed angle α extending to each other. Preferably, they are also integrally formed hereby. The angle α, removed between the geometric longitudinal axes of the two or adjacent control cabinet key is 45 ° in the embodiment. He can also take, for example, 20, 30, 40 ° or any intermediate values. According to the fixed connection with each other and / or in any case based on a rotation about a longitudinal axis of a key rotationally fixed arrangement of a key on the (respective) middle part when using a key in the usual way a moment can be applied.

The middle parts 4, 5 are detachably connected to each other, which will be further discussed below in connection with the Fig. 5 to 7 is explained.

The keys 2 respectively connected to a central part 4 or 5 form a unit E ₁ or E ₂ .

Next, the units E ₁ , E ₂ , or the middle parts 4, 5, for example, by a chain 6, catch-connected with each other. Also in the separated state, approximately according to Fig. 4 , it is impossible that you lose one of the middle parts about.

In the connected position of the summary, like this Fig. 1 but also in particular the Fig. 2 and 3 shows, there is a key 2 of the in the exemplary embodiment is connected approximately to the middle part 4, between two keys 2 'and 2 ", which are connected to the central part 5. The keys 2, 2' and 2" extend in a star shape relative to each other and that preferably, as from the Fig. 2 and 3 approximately also visible, with a projection in the same angle with respect to their geometric center axes a of the embodiment 45 °.

Each key 2 has a key head 7, which is freewheeled radially outward, and a key shank 8 which, in contrast, extends to the middle.

The key shanks 8 are formed in each case cylindrical in the embodiments. You can also have, for example, a rectangular or square cross-section. In the summarized state according to Fig. 1 all keys 2, 2 ', 2 "extend in a same height band b, see, for example Fig. 5 , In the embodiment, the geometric center axes a are even provided in virtually the same plane. Preferably, two opposing keys 2 are also provided with coincident center axes a.

A foot section 9 of a key 2, see for example Fig. 5 extends in the connected state of the units in the direction of extension of the key 2 in register to the two middle parts 4, 5. The key 2 of the embodiment according to Fig. 5 Although it is rooted only in the middle part 5. Due to the increase in its shaft thickness, starting from a foot region 10 immediately after the middle part 5 to a cross section 11, it preferably increases by the thickness of the second middle part 4. It increases approximately to one twice the thickness (based on the example in Fig. 5 visible dimension transverse to the extension of the geometric longitudinal axis) of the thickness in the foot area.

The connection of the two middle parts 4, 5 and thus each associated key 2 can on the one hand by simple plug-in connection, as in Fig. 5 shown to be achieved. This by a certain clamping effect is generated, for example.

To reinforce this clamping effect targeted, can also be a plastic insert 25 as in the embodiment of Fig. 6 shown to be provided in the cooperation area of the middle parts. The plastic insert 25 results in a resilient mounting, so that the plug combination and connection in the assembled state is thus favorable brought about. The clamping action and / or plastic insert can also be provided in other embodiments, even if this is not described separately again below.

In the embodiment of the Fig. 7 is a magnetic connection, in the embodiment with two individual magnet parts or magnetizable parts 12, 13 are provided. It can also be a magnetic part 12 and 13 suffice if the other center part is designed to be magnetizable overall.

In the embodiment of the Fig. 8 the cohesion chain 6 in both middle parts 4, 5 is guided in each case by two openings 14,15. This makes it easier, in particular, if you only keep the chain that the two parts, for example, if a magnetic closure is provided, find themselves automatically and lock against each other. This can also be provided in each case in further embodiments.

It is also important that at least in the embodiment of the Fig. 1 to 8 , which however can also be provided in the other embodiments, the middle part 4 or 5 itself has a key formation 26 here in the form of a triangle with cut off points. This Schlüsselausformung opens visible perpendicular to the key heads of the key. 2

In particular, in the embodiments of the Fig. 1 to 8 Preferably, but also possible in the embodiments described below possible that keys of different lengths are provided. In particular, based on the embodiments of Fig. 1 to 8 in that all keys belonging to a unit E ₁ or E _{2 are} each designed to be longer or shorter in each case. Thus, on a unit E ₁ having only the longer keys, the keys which are most frequently used may be formed, whereas the shorter keys formed on the unit E ₂ are known to be less frequently used. A shorter key is shorter than the smallest key of the longer key. Thus, in the largest number of applications, it is not necessary to separate the units E ₁ , E ₂ because the shorter keys that preferably extend on the bisecting line between the longer keys do not interfere because of the different length training. Basically, such is for example in Fig. 2 with respect to the double-bit insert 3, which here belongs to the unit E ₂ , see, for example Fig. 4 while the adjacent keys, which belong to E ₁ , in contrast, have a much shorter length, so that the working range of the double bit insert in the illustrated working position so far protrudes that without disassembly of the parts E ₁ , E ₂ allows use.

The Fig. 9a to 9e show typical key heads. This shows Fig. 9a a square, Fig. 9b a double-beard, Fig. 9c a stepped external square, Fig. 9d a crescent-shaped key, Fig. 9e a, relatively large, screwdriver head and 9f a Mehrkantschraubdreherkopf.

The 10a to 10e show comparable designs, wherein 10a and 10b and 10e Triangular variants and 10c and 10d square variants show.

In the embodiment according to the Fig. 11 to 16 a plurality of individual keys 2, 2 ', 2 "are each formed on the foot side with a plate portion 16. This plate portion has a circular outline in the embodiment with an inner circular opening 17. The opening 17 is also preferably centrally with respect to the plate portion 16. At one The area of the outer edge of the plate section 16 is integrally formed, preferably in one piece, with a key 2. The thickness of a shank 18 of the key 2 exceeds the thickness of the plate section 16. The keys 2 are arranged on a central part 4 forming a collection axis 19 in the handling state Fig. 11 strung one above the other. The collection axis 19 is in detail, such as out Fig. 15 shows, from two intermeshing axle parts 19 ', 19 ", wherein the axle 19' has an internal thread and the axle 19" has an external thread. Both are screwed together. Both axle parts 19 'and 19 "are provided starting from a mounting plate 20 extending.

Due to the Schraubzusammenfassung, wherein here a detent summary or magnetic summary, for example, could be alternatively provided, the support plate 20 can be disassembled and so take out or add one or more keys. A user can in particular, put together an individual summary of cabinet keyboards.

The control cabinet key 2 of the embodiment of the Fig. 11 to 16 are, in their respective plane, rotatably provided to each other. Thus, for use, a cabinet key 2, as in Fig. 16 2, 2 ', 2 "continue to provide the required torque during use.

Especially Fig. 12 also shows that the individual control cabinet keys 2 of this embodiment are each arranged in different planes with respect to their geometric center axes a.

In the embodiment of the Fig. 17 to 22nd are the plurality of control cabinet keys 2, 2 ', 2 "end, ie Fußbereichseitig, with a sliding block, which is rectangular or square in cross-section, formed in its outline, he represents the section of a circular ring by means of these sliding blocks 21 are the cabinet key in this embodiment, see in particular Fig. 21 , in a gate 22, which is formed by the middle parts 4, 5 of this embodiment. The middle parts 4, 5 each represent a shell part, which, in the embodiment preferred, are non-releasably connected to each other. The user can not solve such a connection caused, for example, by crimping or any other deformation action. The shell parts are assembled perpendicular to a plane in which one or more keys 2 extend. They are each formed annular. In particular Fig. 21 can recognize, they overlap on the inside, but leave an opening 23 radially outward. This opening 23 is preferably circulating without interruption. It forms at the same time the exit slit for the tapered foot portion of the key 2 between a key shank and the sliding block.

The preferably each extending in terms of their geometric axes in the same plane key 2 are mutually displaceable on a predetermined by the backdrop circular floor.

As in the case of the embodiment described above, a key 2 can be turned free for handling, as it were.

In further detail, the shell parts are clamped against each other. For this purpose, clamping tongues 27 are cut free on an overlapping shell part, in the exemplary embodiment, preferably starting approximately from a median plane. A multiplicity of clamping tongues 27 are designed to be visible over the circumference.

The keys as well as preferably the middle parts are preferred within the scope of the here described steel parts or sheet steel parts. It may also be, for example, steel castings, at least in terms of keys.

Related to the FIGS. 23 to 25 is a development of the embodiment of FIGS. 1 to 8 shown.

In principle, all statements regarding the particular embodiment mentioned above, with regard to the keys as such and other unaltered sections, also apply to the other embodiments of the description of the figures, to this embodiment. Only the below highlighted features are different. But you can also in the above embodiment of the FIGS. 5 to 8 be realized.

At one of the middle parts, here the middle part 4, see also Fig. 24 , only control key larger length L are formed, while at the other center part only switch key smaller length 1 are formed.

A greater length L is in particular 10% or more greater than a smaller length 1. This may, for example, extend to four times the length.

Of particular importance is also, see in particular Fig. 23 that an outside beard key 7, see also Fig. 9b , Such a length L, which extends an imaginary extension V of the lower edge 28 of a beard, transversely, ie at right angles to a geometric longitudinal axis a of this key, above an adjacent cabinet key 7, namely here a cabinet key smaller length 1 extends. And with one in the representation according to Fig. 23 , ie in the plan view, given distance x, which preferably corresponds to one tenth or more of the shaft thickness 11 in the cylindrical portion of the cabinet key 7 with key bit. More preferably, the distance x _^5/10 up to _^15/10, further preferably from about _^9/10 up to _^10/10 of that thickness 11 corresponds.

Furthermore, it is also preferred that a polygonal socket 29 is composed of two or more inner polygons 30, 31, which have different key widths. Here, the polygon socket 31 is formed with a smaller key width in greater depth of the key head, as the polygon socket 30 larger key width. The transition is preferably given via a step 33.

Furthermore, it is also preferred that the representation in FIG Fig. 7 in both middle parts 4, 5 each a holding magnet 12, 13 is arranged. He may be there, for example, glued.

Surrounding a holding magnet 12 or 13, a groove-like recess 34 is preferably formed in the respective central part 4 and 5 respectively. This groove-like depression can be provided peripherally, is further preferably formed in a circular section, but moreover preferably does not merge into one another.

This groove-like depression 34 has the advantage, for example, that damping material can be accommodated here, which can dampen a joining of the parts of the control cabinet key in a noise-like manner, for example. It may be about foam. Next additionally or alternatively, this recess 34 can also be used as a receiving space for small parts, such as small screws or the like, which can then be suitably held there with appropriate action of the magnet, even with the help of the magnet. Certain additional parts that can be used in this context, can also be easily, for example, by pinching or even single insertion, proceed accordingly mindful when opening, be included there. They can also be accommodated in a holding material, such as foam.

Preferred is also with reference to the illustration according to Fig. 25 in that a radial distance Y, from a central axis M of the summary or a specific part of the summary, to a transition U into the greater thickness 11 of a cabinet key is different Cabinet key of a same part of the summary is different, that is, for example, a distance Y _{1 is} smaller than the distance Y. In the representation of Fig. 25 , which also corresponds to a preferred design, both distances are the same length.

In particular, but is also preferred that, although opposite keys according to the representation of Fig. 25 the distances Y, Y _{1 are the} same, in the other keys of the same part of the summary but the distances Y, Y ₁ are indeed the same, but smaller than the distances of the keys in Fig. 25 are shown.

With respect to the smaller distances is then more preferably at a central part, here the middle part 5, see Fig. 24 , a flattening 35 is formed, which provides a layer-unique assignment of the parts of the summary and also still a rotation of the parts of the summary to each other - possibly additionally - prevents.

Preferably, two such flats 35 are formed in mirror image with respect to the central axis M opposite to the same central part 5. With just one flattening, it can also be achieved that an unambiguous assignment of the middle parts, and thus the key to one another, whereby the respective neighborhood is defined, is given.

As can also be seen, the keys with an inner edge also have an outer shape which corresponds to this inner edge, that is to say a trihedral inner edge or a five-surface inner edge, etc.

4. Combination according to any of the preceding claims, characterised in that the units (E₁, E₂) are interconnected separably but captively, i.e., so that they are not completely separable.
5. Combination according to any of claims 1 to 4, characterised in that, when connected, the keys (2) of the first unit (E₁) extend at least in the projection between two keys (2, 2') of the second unit (E₂).
6. Combination according to any of the preceding claims, characterised in that one or more control cabinet keys (2) are formed as neighbouring control cabinet keys (2) having a greater length, the length (L) of a control cabinet key (2) of greater length exceeding the length (I) of a control cabinet key (2) of shorter length by 10 % or more, preferably up to 400 %.
7. Combination of control cabinet keys according to any of the preceding claims, characterised in that a control cabinet key (2) of greater length (L) has a key bit, and in that a bottom edge (28) of the key bit does not encounter an adjacent key, at least on one side, in an imaginary extension (V) at a right angle to a longitudinal axis (a) of said key (2), in the plane of the control cabinet keys (2) mounted on a centre part (4, 5).
8. Combination according to claim 7, characterised in that the extension (V) does not encounter an adjacent key on either side.
9. Combination according to any of the preceding claims, characterised in that one key (2) is designed as an internal polygon, and in that a plurality of key widths are formed over the depth of the internal polygon, the transition of the key widths preferably having a step-like configuration.
10. Combination according to any of the preceding claims, characterised in that an exterior key shape matches an interior key shape.
