Description

Summary of cabinet keys

The invention initially relates to a summary of control cabinet keys, wherein individual keys are arranged in a same plane but extending at a fixed angle to each other and connected via a common middle part and according to the fixed connection with each other during handling a moment on a used key can be applied. The invention further relates to a summary of control cabinet keys, wherein individual keys are provided extending at an angle to each other and by means of a central part connecting these keys when handling a moment on a used key can be applied. Such summaries of control cabinet keys have already become known in many ways. Reference is made, for example, to DE 296 17 973 Ul. 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. The keys of a summary usually have 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. 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 the other unit can not be lost even when handling a key in a separate unit.

A further possible solution of the problem is given in a summary in which the keys are rotatable relative to each other but only in a respective predetermined plane. Due to the rotatable arrangement of keys, more keys can be provided in the summary, basically in a star-shaped manner relative to one another, than with a conventional handle. exercise 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.

Further features of the invention are described below, also in the figure description and in the drawing, often in their preferred assignment to the claim concepts already explained above, but they can also be assigned to only one or more individual features described herein or illustrated are, in particular, individual of the already negotiated claim 1 or 2, or in another overall concept of importance. In particular, for example, also in an embodiment in which the units are not, at least not operationally simple, separable or the combination of the units is even provided as a non-removable complete unit.

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 conveniently achieved. 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 aforementioned 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 composite 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 , can achieve a given positional alignment of the middle parts to one another and / or one, possibly also additional, rotational blocking.

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 significance with regard to the embodiment in which the control cabinet keys are non-rotatably relative to one another at predetermined angles. 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 scarf tschankschlüssel greater length four times the length than the control cabinet 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 with one, preferably not with the two - one on each side in Umf angs 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 driver, the head of the key in which the internal reciprocator 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 one above the other in the area of their foot parts and held together by the axle.

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, which each form 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, initially having to be separated from one another.

With regard to the disclosure, the ranges and ranges of values given above and below also include all intermediate values, in particular in ¹ 1o steps of the respective dimension, if necessary also dimensionless, for example ¹ /10%, etc., on the one hand to delimit the mentioned Range borders 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.

24, cut along the line XXV-XXV. The embodiment of FIGS. 1 to 8 relates to a summary 1 of cabinet keys 2, in the embodiment, as also preferably provided, even with a Doppelbiteinsatz 3. The individual keys 2 are each, see in particular Fig. 4, with a first middle part 4 or a second common middle part 5 connected. 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 a, removed between the geometrical 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 explained further below in connection with FIGS. 5 to 7.

The keys 2 respectively connected to a middle part 4 and 5 form a unit Ei or E ₂ .

Next, the units Ei, E ₂ , and the middle parts 4, 5, for example, by a chain 6, catch-connected with each other. Even in the separated state, for example according to FIG. 4, it is precluded that one of the middle parts loses approximately.

In the connected position of the summary, as is apparent from Fig. 1 but also in particular Figs. 2 and 3, 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 shown in FIGS. 2 and 3, for example, with an angle which is the same in the projection with respect to their geometric central axes a of the exemplary embodiment 45 °.

Each key 2 has a radially outwardly freestanding key head 7 and a contrast to the center extending key shank 8. The key shanks 8 are each formed in the embodiments cylindrical. You can also have, for example, a rectangular or square cross-section. 1, all keys 2, 2 ', 2 "extend in the same height band b, see for example FIG. 5, wherein in the exemplary embodiment the geometric center axes a are even provided in virtually the same plane are each two opposite key 2 provided with coincident center axes a.

A foot section 9 of a key 2, see approximately Fig. 5, extends in the connected state of the units in the extension direction of the key 2 in registration to the two middle parts 4, 5. The key 2 of the embodiment of FIG. 5, although rooted only in However, 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 enlarges by the thickness dimension of the second middle part 4. It enlarges approximately to twice the thickness (relative to the dimension visible for example in FIG. 5 transverse to the extent of the geometric longitudinal axis) of the thickness in the foot region. The connection of the two middle parts 4, 5 and the respectively associated key 2 can be achieved on the one hand by simple plug connection, as shown in Fig. 5. This is generated by a certain clamping effect, for example.

In order to purposefully reinforce this clamping action, a plastic insert 25, as shown in the embodiment of FIG. 6, can also be provided in the area of cooperation of the central 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 effect and / or plastic insert can also in other embodiments, even if this is not described separately again below, be provided.

In the embodiment of FIG. 7, a magnetic connection, in the embodiment with two individual magnet parts or magnetizable parts 12, 13 is 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 FIG. 8, the cohesion chain 6 in both middle parts 4, 5 is guided in each case through two openings 14, 15. This makes it easier, in particular, if one only holds the chain, that the two parts, for example when a magnetic lock is provided, find themselves automatically and lock against one another. This can also be provided in each case in further embodiments. It is also important that in any case in the embodiment of FIGS. 1 to 8, which may 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, it is also possible in the embodiments of FIGS. 1 to 8, but also possible in the embodiments described below, that keys of different lengths are provided. In particular, based on the embodiments of FIGS. 1 to 8, that all keys belonging to a unit Ei or E _{2 are} each designed to be longer or shorter in each case. Thus, on a unit Ei which has only the longer keys, the keys which are used most frequently can be formed, whereas the shorter keys formed in the unit E _{2 are} experience 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 Ei, E ₂ from one another, since the shorter keys, which preferably extend on the bisecting line between the longer keys, do not disturb because of the different length training. In principle, such is given, for example, in FIG. 2 with regard to the double-bit insert 3 which here belongs to the unit E ₂ , see for example FIG. 4, while the adjacent keys belonging to Ei, on the other hand, have a significantly shorter length, so that the working range the Doppelbiteinsatz in the illustrated working position so far protrudes that without disassembly of the parts egg, E _{2 is} possible use. Figs. 9a to 9e show typical key heads. 9a shows a square, FIG. 9b shows a double bit, FIG. 9c shows a stepped external square, FIG. 9d shows a half moon key, FIG. 9e shows a comparatively large screwdriver head and FIG. 9f shows a polygonal screwdriver head.

FIGS. 10a to 10e show comparable designs, FIGS. 10a and 10b and 10e show triangular variants and 10c and 10d show square variants.

11 to 16, a plurality of individual keys 2, 2 ', 2 "are each formed on the foot side with a plate section 16. In the exemplary embodiment, this plate section has a circular outline with an inner circular opening 17. The opening 17 is also preferably central with respect to the plate portion 16. A portion of the outer edge of the plate portion 16 is integrally formed, preferably integrally, with a key 2. The thickness of a shank 18 of the key 2 exceeds the thickness of the plate portion 16. The keys 2 are on one 11. The collecting shaft 19 consists in detail, as can be seen for example in FIG. 15, of two intermeshing axle parts 19 ', 19 ", wherein the axle 19' is an internal thread and the axle part is axle-19 19 "has an external thread, both of which are screwed together n. 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 Figs. 11 to 16 are rotatable relative to each other in their respective plane. Thus, for use, a control cabinet key 2 can be freely rotated as shown in Figure 16, adjacent control cabinet keys 2, 2 ', 2 "further allowing for the required torque to be applied in use individual control cabinet keys 2 of this embodiment with respect to their geometric center axes a are each arranged in different planes.

In the embodiment of Figures 17 to 22, the plurality of scarf cabinet wrenches 2, 2 ', 2 "are formed at the end, ie at the foot end, with a sliding block which is rectangular or square in cross section 21, in a gate 22 formed by the middle parts 4, 5 of this embodiment, by means of these sliding blocks 21. The middle parts 4, 5 each constitute a shell part The user can not resolve 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 in a circular ring, in particular FIG 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 overarching 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.

With reference to FIGS. 23 to 25, a development of the embodiment of FIGS. 1 to 8 is 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 they can also be realized in the said embodiment of Figures 5 to 8.

At one of the central parts, here the central part 4, see also Fig. 24, only control key larger length L are formed, while at the other middle 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 outboard key 7, see also Fig. 9b, has such a length L, which is 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. Namely, with a given in the illustration of FIG. 23, ie in 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 / io corresponds to ¹⁵ / io, moreover preferably about ^9/10 to ¹⁰ / of the said thickness 11th

Furthermore, it is also preferred that an internal polygon 29 is composed of two or more internal 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 according to the illustration in 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 may be provided peripherally, is more preferably formed in a circular section, but moreover preferably does not extend 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 simply be accommodated, for example, by pinching or simply inserting them, whereby care must be taken when opening them. They can also be accommodated in a holding material, such as foam. It is also preferred with reference to the illustration according to FIG. 25 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 control cabinet key is different Switch cabinet key of a same part of the summary is different, that is, for example, a distance Yi. Is smaller than the distance Y. In the illustration of Fig. 25, which also corresponds to a preferred design, both distances are the same length.

In particular, however, it is also preferred that although the distances Y, Yi are the same in the case of opposite keys as shown in FIG. 25, in the other keys of the same part of the summary, the distances Y, Yi are also equal, but smaller than the distances the key, which are shown in Fig. 25.

With regard to the smaller spacings, a flattening 35 is then further preferably formed on a central part, in this case the central part 5, see FIG. 24, which provides a positionally unambiguous assignment of the parts of the summary and, in addition, a rotation of the parts of the summary to one another - if necessary in addition - hinders.

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. All disclosed features are essential to the invention. The disclosure of the associated / attached priority documents (copy of the prior application) is hereby also incorporated in full in the disclosure of the application, also for the purpose of including features of these documents in claims of the present application. The subclaims characterize in their optional sibling version independent inventive development of the prior art, in particular to make on the basis of these claims divisional applications.
