Description

The invention relates to an input unit for inputting a code, in particular an input unit for entering a code for electronic lock cylinder, according to the type specified in the preamble of claim 1 and an electronic lock cylinder according to the specified in the preamble of claim 14. Art.

Electronic lock cylinders are well known in the art. Only by way of example is on the DE 10 2006 045 195 B3 directed by:

Such electronic lock cylinder are installed in particular in mortise locks of doors and have a cylinder body in which an axis is rotatably mounted, which is rotatably connected to an outside knob. In addition, a lock cam is rotatably mounted in the cylinder body, can be operated via the latch and latch of the mortise lock. For this purpose, the electronic lock cylinder have either a coupling unit or a locking unit. The coupling unit provides only in the activated state a rotationally fixed connection between the axis and closing cam ago; in the idle state, however, the axle rotates freely, so that from the outside no lock operation is possible. The alternative locking unit allows only in the activated state, an actuation of the closing cam on the axis, while in the idle state, the actuation of the axle is locked. Furthermore, such electronic lock cylinder have an evaluation and control electronics, which evaluates the validity of an access authorization and switches the coupling or blocking unit time-limited from idle state to the activated state with a valid access authorization. The necessary energy supply of the electronic components of the electronic lock cylinder is effected by a battery. As access authorization usually transponder or chip key are used. Therefore, the electronic cylinders are equipped with reading units for such authorization carriers. Frequently, cylinders are searched for on the market, which alternatively or in addition to transponders or chip keys also enable actuation by entering a code. In this respect, the problem arises of connecting electronic lock cylinders with an input unit for inputting a code.

A generic, all features of the preamble of claim 1 having input unit for inputting a code is in the DE 10 2012 009 624 B4 disclosed. A disadvantage here proves that due to the keyboard-like surface marking the code input unit for a third party as such is immediately recognizable, so that in this way a third party could be encouraged to spy on the code.

The invention is based on the object an input unit for entering a code according to the type specified in the preamble of claim 1 such that allows an easy-to-perform code entry, while the input unit as such, however, is not immediately apparent to third parties.

This object is achieved by the characterizing features of claim 1 in conjunction with its generic features.

The dependent claims form advantageous developments of the invention.

In a known manner, the input unit for inputting a code comprises a rotatable actuating means with an actuation surface having actuation areas, and a touch sensor arranged below the actuation surface with n touch fields associated with the actuation fields, where n> 1.

Only for the sake of completeness it is pointed out that present n is to be construed as a placeholder for the number of existing fields of operation or touch fields, so means z. B. n = 5, that the rotatable actuating means 5 has actuation fields and arranged below the actuating surface touch sensor corresponding to 5 touch fields.

According to the invention, the actuation means has at least one perceptible marking positioned in such a way that the position of one of the n actuation fields of the actuation surface can be unambiguously identified via the position of the at least one perceptible marking. The clearly identifiable by the marking operation field is hereinafter also referred to as the first operating field. It is further provided according to the invention that the remaining n -1 actuation fields are positioned so that from the position of the first actuation field a clear conclusion on the position of the remaining n-1 actuation fields is possible.

The embodiment according to the invention proves to be advantageous since for identification of the fields of operation - labeling of the actuation fields is no longer required, so that the input unit comprehensive actuating means externally of a "normal" actuating means, ie an actuating means without code input unit, not to distinguish. This has the positive effect that the input unit for third parties as such is not immediately recognizable, which has a beneficial effect on safety, since the risk of potential spying is reduced.

Preferably, the actuating means has only a single perceptible marking. An alternative embodiment provides that the actuating means comprises two perceptible markings arranged offset by 180 ° or 90 °.

Preferably, the n-1 actuation fields are relative to the first actuation field, i. in relation to the operating field uniquely identifiable by the marking, in a geometric pattern, e.g. Triangle / square pattern, and / or at a defined angular distance, such. B. circumferentially offset by 90 °, respectively. As a result, an intuitive detection of the position of the n-1 operating fields is ensured in an advantageous manner.

According to a first embodiment of the invention it is provided that each of the n actuation fields is assigned a fixed value. This has the advantage that in each position of the knob an immediate code entry is possible. If, for example, the actuating means has a single perceptible marking, then according to this first embodiment it is irrelevant for the code entry whether the marking is at "12 o'clock", or "3 o'clock", or "6 o'clock position", etc.

A second embodiment of the invention is characterized in that only at a predefined position of the perceptible marking (s) the n actuation fields is assigned a fixed value. For example, if the actuating means again only a single perceptible marking, this embodiment has the effect that z. For example, if the only detectable mark is at the 12 o'clock position, each of the n actuation fields is assigned a fixed value and code entry is enabled only in this predefined 12 o'clock position. The advantage here is that due to the fixed code input for the position input of the actuating means, the code input is facilitated.

A particularly preferred third embodiment of the invention provides that in the case of a defined position of the perceptible mark (s), the n actuation fields are assigned a stationary value. If, for example, the actuating means has two perceptible markings offset by 180 °, and as a defined position z. B. deposited a substantially horizontal and / or vertical orientation of the two perceptible markings, it is - when the operation field is in this position - the n operating fields assigned a stationary value. For example, B. the operating field n = 4 fields of activity, which are arranged circumferentially offset by 90 °, and as a defined position is a substantially horizontal and vertical orientation of the two noticeable marks deposited, so is to be understood by the phrase "fixed value" in the case of a substantially horizontal or vertical orientation of the two perceptible markings, for example, the operating field at 12 o'clock, the value "1", the operating field at 3 o'clock, the value "2", the operating field at 6 o'clock, the value "3" and the operating field at 9 o'clock is assigned the value "4".

Preferably, the values assigned to the n fields are alphanumeric characters.

According to a further advantageous embodiment, it is provided that by double-clicking, longer pressing and / or pressing with greater pressure, the actuation fields can be assigned further values. For example, If, for example, the rotatable actuating means has n = 5 operating fields, further 5 values can be assigned to the n = 5 operating fields by a corresponding double-click, longer pressing and / or pressing with greater pressure. As a result, a greater security is guaranteed because the same code length more input characters are provided.

A further preferred embodiment of the invention provides that the perceivable marking (s) is designed as a haptic, tactile perceptible marking, in particular in the form of a good or easily palpable elevation or depression. The formation of the mark as a tactile mark has the advantage that thereby also a detection in low light conditions, such. B. at night, is ensured.

A particularly preferred embodiment provides that the perceptible mark (s) is in the form of a recessed grip (s) introduced into the rotatable actuating means. Due to the functional integration of marking and recessed grip is advantageously ensured that the actuating means without external or for an actuating means u. U. atypical mark can be formed so that it is not apparent to a third party that the actuating means serves as a code input unit.

Preferably, the rotatable actuating means of the input unit is a rotary knob of an electronic lock cylinder.

A known disadvantage of electronic lock cylinders, which are to be opened by entering a code or to operate, is that due to the necessary code input unit the Electronic lock cylinders are easy to identify. This in turn means that such lock cylinder can be identified by third parties as potential vulnerabilities, so that third parties by appropriate Ausspähmaßnahmen in the code input gain knowledge of the code and thus gain access to unauthorized.

Therefore, the invention further the object of developing an electronic lock cylinder according to the type specified in the preamble of claim 14 such that while avoiding the above disadvantages, a higher safety standard of the electronic lock cylinder is guaranteed.

This object is achieved by the characterizing features of claim 14 in conjunction with its preamble features.

In a known manner, this includes the electronic lock cylinder rotatably mounted in a cylinder body axis, a cylinder body rotatably mounted in the locking cam for actuating a door lock, an outer knob which is rotatably connected to the axis, a coupling or locking unit, the only in the activated state establishes a rotationally fixed connection between the axis and closing cam or an actuation of the closing cam on the axis allowed, an input unit for entering a code, a battery, as well as an evaluation and control electronics, after entering a valid code, the coupling or locking unit time-limited from Sleep state switches to an activated state.

According to the invention the input unit is designed according to one of claims 1 to 13, wherein the actuating means of the input unit forms the outer rotary knob of the electronic lock cylinder.

Due to the previously described embodiment of the input unit is ensured in an advantageous manner that for a third party, the input unit and thus the electronic lock cylinder is not immediately recognizable as a code to be actuated via a lock cylinder, with the consequence that unauthorized third parties do not spy on the Codes are encouraged so that a higher safety standard of the electronic lock cylinder is ensured.

Further advantages and possible applications of the invention will become apparent from the following description in conjunction with the embodiment shown in the drawing.

• 5 der Drehknauf aus 4 in einer ersten definierten Lage zur Codeeingabe, und
• 6 der Drehknauf aus 4 in einer zweiten definierten Lage zur Codeeingabe.

In the description, the claims, and the drawing, the terms and associated reference numerals used in the list of reference numerals below are used. In the drawing:

• 1 a sectional side view of an electronic lock cylinder;
• 2 a plan view of the end face of serving as input unit for entering a code knob of the lock cylinder 1 .
• 3 Turn the knob off 2 in a rotated position by 90 °;

1 shows a total with the reference numeral 10 designated electronic lock cylinder. The electronic lock cylinder 10 includes a cylinder body 12 , which is inserted into a mortise lock of a door and screwed with a forend screw against the lock. In the cylinder body 12 is an axis 14 rotatably mounted, the rotation with an external knob 16 connected is. The outer knob 16 serves - as will be explained later - as input unit for entering a code. In the cylinder body 12 is also a locking cam 18 rotatably mounted, regardless of the axis 14 can be rotated and the lock and latch of the lock operated on rotation.

The electronic lock cylinder 10 also has a knob on the inside of the door 20 , which is independent of the axis 14 can be turned. In the inner knob 20 there is a turntable 22 that with the axis 14 rotatably connected. An evaluation and control electronics 24 and a battery 26 are non-rotatable with the rotary plate 22 - And thus rotatably with the axis 14 and the outer knob 16 connected.

In the axis 14 is a coupling unit 28 arranged by a motor 30 is driven. In the axis 14 is a co-rotating cable 32 guided, which is the input unit for entering a code, coupling unit 28 , Engine 30 , Evaluation and control electronics 24 and battery 26 connects with each other. All electrically relevant components of the lock cylinder 10 are co-rotating with the axis 14 arranged and therefore can be wired together in a simple manner.

In the evaluation and control electronics 24 validly stored codes are stored. To Entering a valid code becomes the engine 30 energized for a limited time. The motor drives for the duration of the energization 30 the coupling unit 28 from the resting state to the activated state in which they lock the cam 18 to the axis 14 coupled and thus a lock operation on the outer knob 16 allows. After a defined time the engine is running 30 the coupling unit 28 return to sleep. This turns the outer knob 16 free again and no longer allows lock operation.

The input unit for entering a code is in the outer knob 16 integrated.

This is - how 2 shows - the end face of the outer knob 16 is formed as an actuating surface 34 and in the present case has n = 5 actuation fields. The fields of operation are shown for clarity with a dash-dotted outline and the reference numerals 100-1 . 100-2 . 100-3 . 100-4 and 100-5 designated. Below the actuating surface 34 is a - not shown here-touch sensor with corresponding to the fields of activity 100-1 . 100-2 . 100-3 . 100-4 and 100-5 associated with associated touch fields, on the one actuation of the actuation fields 100-1 . 100-2 , 100-3, 100-4 and 100-5 is detected and over the cable 32 to the evaluation and control electronics 24 is supplied.

As 2 it can be seen further in the area of the operating field 100-1 in the lateral surface of the rotary knob 16 a mark 36 brought in. The mark 36 is present in the form of a small milled and thus easily tactile groove formed so that by palpation of the mark 36 a clear conclusion about the position of the operating field 100-1 , hereinafter also referred to as the first operating field, is possible.

As 2 further shows are the remaining ones 4 fields of activity 100-2 . 100-3 . 100-4 and 100-5 in relation to the mark 34 clearly identified first field of activity 100-1 arranged in an easy-to-remember geometric pattern, so that from the location of the first field of activity 100-1 a simple conclusion on the location of the remaining 4 fields of activity 100-2 . 100-3 . 100-4 and 100-5 is possible.

In the present case, the operating fields are assigned a fixed numerical value, namely the operating field 100-1 the value 1 , Field of activity 100-2 the value 2 , Field of activity 100-3 the value 3 , Field of activity 100-4 the value 4 and field of activity 100-5 the value 5 , For clarification, the respective assigned value is shown in the dash-dotted box.

Is z. For example, if the number sequence 114352 is a valid access code, the operating fields are for the opening of the lock cylinder 100-1 . 100-1 . 100-4 . 100-3 . 100-5 and 100-2 to press.

As the fields of activity 100-1 to 100-5 a fixed value can be assigned - like 3 shows - the entry of the code in any position of the rotary knob 16 be made.

An alternative embodiment is in 4 to 6 shown. In the present case, the knob 16 two markings offset by 180 ° 36 on. Only with a defined position of the two markings 36 the operating fields are assigned a stationary value. In the present case is as a defined position, ie the position of the markers 36 in which the operating fields are assigned a stationary value, a substantially horizontal alignment of the two markings 36 , see. 5 , and a substantially vertical alignment of the two markers 36 , see. 6 , deposited.

Ie. at the in 4 shown position is a code input only difficult possible.

But are now - as in 5 shown - the two marks 36 aligned substantially horizontally, the operating fields are assigned fixed values, z. B. in the form that the then 12 Clock located activity field of value 1 , the field of operation at 3 o'clock is the value 2 , the operating field at 6 o'clock is the value 3 , the operating field at 9 o'clock is the value 4 and the central field of action is the value 5 is assigned.

Accordingly, even with a substantially vertical alignment of the two markings - as in 6 The operating fields assigned to the above-mentioned fixed values, namely the operating field then at 12 o'clock, are the value 1 , the field of operation at 3 o'clock is the value 2 , the operating field at 6 o'clock is the value 3 , the operating field at 9 o'clock is the value 4 and the central field of action is the value 5 assigned.

If now - as above - the code 114352 is to be entered, the rotary knob must first be entered 16 be turned so that the two marks 36 horizontally or vertically aligned, cf. 5 respectively. 6 , Then, the operation field at 12 o'clock is to be pressed twice, followed by the at 9 o'clock, the at 6 o'clock, the central and the 3 o'clock operating field.

An advantage of this embodiment is that - especially if the two markings 36 are designed as recessed grips - the knob 16 can be quickly and intuitively positioned and thus a simple code entry is possible.

Only for the sake of completeness, it is finally pointed out that both the drawn dot-dashed outline and the numerical value shown serve only for explanation and, of course, are not present in the "finished" product.
