Abstract

The lock (10) has a radio transmitter that can be coded using a keypad (14). The signals of the radio transmitter control and operate a locking unit. The coded lock includes a closed, chemical resistant and waterproof outer surface (13), a keypad and inside identifications (e.g. number, symbols).

Description

The invention relates to a code lock according to the preamble of claim 1.

In particular, for use with garages and yard gates, one uses (also) radio code locks. This is a programmed with a code radio transmitter through Enter the correct code that activates the associated garage or yard gate controls the same way as is known and customary for handheld transmitters.

For the coding are often foil or rubber keyboards, although Rub on printed symbols or numbers in the course of use, so that the Code can be visible. Also, damage is easily possible, such as through Scratching with fingernails, burning cigarettes, super glue and the like. to Remedy you can use stainless steel keyboards, the far less sensitive, however are significantly more expensive. Here too, mechanically movable parts can be glued and become unusable.

DE 201 21 751 U1 sees a house installation facility for a building entrance area with a control panel in front, which has a glass body with integrated elements an intercom, a door opener and the like. has and in or beside an entrance door or in a door handle is arranged. The control panel is used two closely opposite glass plates with electrically conductive, transparent Circuit traces, the gap must by a circumferential seal against Pollution and moisture are protected. On the operating page is located a curved thin glass plate, which by mechanical pressure on its surface a Contact on a thicker backing plate. In one embodiment, so a ten-key for a code lock are operated, such as a transponder for the door opener to activate. Also, a sensor for capturing fingerprints be integrated into the control panel. The disadvantage, however, is that the User facing thin glass plate must be bendable and therefore not can be vandal-proof. In addition, a numeric keypad can hardly perform flat, because you would need a whole lot of distance to get one avoid unwanted simultaneous operation of several keys. The constructive and manufacturing effort is naturally high.

This also applies to a communication device according to DE 299 13 108 U1, the at least two successively arranged functional discs needed. An outer one Disc has an input keypad with functional elements in the form of buttons that Pressure contactor can be to printed conductors or capacitive switches. An inner one Disk carries e.g. a video camera and a third disc can have a speaker or a microphone. Verso Is an interface with fasteners for Installation Provided in a (flush-mounted) wall socket.

It is an important object of the invention to address these and other disadvantages of the prior art Technology with the most economical means to overcome and improved To create a code lock that combines robustness with longevity. The aim is a device of simple construction that is vandal-proof and convenient to use.

Main features of. Invention are given in claim 1. Embodiments are The subject matter of claims 2 to 10.

In a code lock Especially for garage and yard gates, with one on one Glass plate arranged keypad for coding a radio transmitter whose signals control a closing device or actuate, sees the invention according to claim 1 that the solid and plan formed glass plate a closed, chemical and waterproof exterior or control surface, also inner markings and has the externally visible keypad. The novel code lock offers the Price advantage of a membrane keyboard, but in contrast to such a durable and largely stable against external influences. Insbeondere is the construction vandalism resistant, so that the inner markings such as numbers, symbols, etc. always remain displayable and the keypad is safe to use.

In an advantageous embodiment, the keypad capacitively actuated sensor surfaces for fingerprint-free electronic switching, whereby the external or control surface is a bare, free of electrically conductive elements glass surface.

This gives you the important possibility of gentle electronic switching without pressure on mechanically moving or even fracture-prone parts.

On its inside, the glass plate has a ladder structure, namely comb or Meandering nested electrodes as sensor surfaces In such a grouping, that they form the keypad. Also on the inside are expediently self- or illuminated displays and / or markings arranged preferred further at least one electronic assembly, e.g. an integrated evaluation electronics or logic devices and / or radios. In any case, you have one Thanks to this training, a sturdy device that offers low production costs can be produced and has grown to great demands.

The glass plate can be illuminated in a planar manner, in particular by means of laterally or from above radiating in LEDs. The internal displays and / or markings can be trained self-or luminescent. Preferred is each key or sensor surface a light emitting diode at least functionally, in particular spatially assigned.

Important advantages of the novel code lock are that it is capable of learning, by giving at least one of a user permission and / or a use release a changeable memory space is available. For example, a 6-digit User code to be entered, which is a serially encoded radio signal of the transmitter changes. An access authorization can be programmed individually.

As can be seen from Fig. 1 and Fig. 2, has a code lock 10 according to the invention a Housing 15, which preferably has a weather canopy 16, a glass plate 12 through its outer surface 13 therethrough is a keypad 14 and a row of status indicators 17 and a reception indicator 18 can be seen on the back of the glass plate 12 are applied. At least one edge of the glass plate 12, e.g. at the upper edge, a lighting 19 e.g. arranged by light emitting diodes (LEDs) be, the laterally interspersed light a flat illumination of the code lock 10 effect. Also indicated is a power supply cable 20 a network cell (not shown) and a data line 23 for electronic devices. These can be located on the back of the glass plate 12, where as well Markings 25 are provided. To the electronic devices belong Namely, a logic module 21. a 22 designated radio transmitter B and a with 24 designated radio receiver A.

It can be seen that the code lock 10 with its glass plate 12 is a wired Communication is possible, e.g. in 2-wire technology or - in anaerified version - in 2-wire technology and / or with radio transmitter. A hand-held transmitter 11 does not have to be a physical one Be part of the code lock 10. The logic unit 21 can optionally data by 2-wire technology and / or received by radio, with an operator on the display 18 is signaled that his command has arrived. This is helpful if e.g. a Bell is far away and thus an acoustic feedback would be missing. The Shutdown of the receiver 24 takes place, for example, over time.

The front or glass plate 12 is made of standard glass or safety glass and is preferably transparent. Important is a single-layer structure with rear keyboard 14th and the Ausleuchtbarkeit by means of LEDs, displays 17/18, etc.

The keypad 14 usually consists of a numeric keypad with touch keys, e.g. with buttons 1 ... 9 and K, 0, R. The front of the keypad 14 is free of any Imprint or any markings. The hard and smooth surface ensures Resistance to abrasion, contamination and mechanical effects with fingerbogs, cigarettes, knives, etc. Because the surface has no breakthroughs for key buttons, LEDs or the like. also has resistance to water and other liquids (e.g., beverage residues), chemicals, superglue, etc. secured. To avoid misrecognition, the housing 15 is for use designed outdoors so that the key surfaces 14 through the canopy 16 before direct Splashing water and driving rain are protected.

The keys of the field 14 are sensor keys in which by finger rest the Capacitance of a sensor surface 26 is changed. This forms part of a ladder structure 28 and preferably has two separate conductor arrangements, e.g. Comb- or meander-shaped and are mutually a basic capacity exhibit. Finger rest increases this capacity. The logic unit 21 evaluates the change from and generates a switching command to the respective digit.

The back of the glass plate 12 is printed inversely with markings 25, e.g. With through the glass pane 12 readable digits. Furthermore, the conductive sensor surfaces 26 and their feeds printed. If necessary, an A radio receiver 24 and a B-radio transmitter 22 are applied with. The power supply is expediently with battery operation; alternatively or additionally can be about the Line 20 connect a (not shown) power supply.

From Fig. 3 it can be seen that a code lock 10 - here as a dot-dashed frame indicated - the keypad 14 with the logic board 21, the B-radio transmitter 22nd and the A-radio receiver 24 may include. If the code lock 10 is operated, then go signals to a - dashed framed drawn - closing device 29, namely from the radio transmitter 22 to the radio receiver 31 and / or from the logic 21 via the data line 23 to the transmitter 30. Both act on a gate control 32, in particular a drive (not shown) for a gate 33 controls.

For use for garage and yard gates a radio code lock is provided, which is how to use a hand-held transmitter 11. It has the same system data - namely Frequency, modulation type, number of bits, repetition rate, etc. - as such, but there one instead of a direct operation for the activation of the radio code lock additionally a sequence of digits for user legitimation and approval. A transmitter and A receiver, B transmitter and B receiver are each other e.g. assigned in terms of frequency. Of the Operation is carried out on the toll-free European ISM band 27 MHz, 40 MHz, 433 MHz, 868 MHz, 1200 MHz and 2400 MHz, preferably 433 MHz and 868 MHz. In the US, a 300 MHz band is allowed.

The following are procedures and coding schemes and programming Depending on the task, each offers a benefit optimum.

example 1

A user legitimation code directly changes a serially encoded radio signal so that a learning and storage process is not necessary. The user legitimization code consists of e.g. from a 6-digit number, but you would In Fixed Programming too add or clear a factory code to the 6-digit number, which is continuously ex works is changed for each code lock and a direct change of the serial coded Radio signal causes. For example, 6 bits become a 40-bit serial encoding changed, which is recognized by a farm gate drive. The change of the factory code each code lock leads bel the same 6-digit number to a different coding Lelting or radio coding. This ensures that a code equality can not occur. If several radio code locks approximately on a garage door drive each radio code lock is inserted, the number of Radio code locks of those of the learning processes and memory locations in the garage door drive equivalent. This applies analogously for 2-wire operation.

Example 2

For this purpose, a changeable memory space in the code lock 10 is provided. By change (Reprogramming) of the consecutive factory code can be a code equality be set in the radio signal. Therefore, with just one learning / storage space Any number of radio code locks on the locking device in the garage door drive 29 work. This also applies analogously for 2-wire operation.

Example 3

This corresponds to the previous example 2. To change the user permission is a changeable memory space in the code lock 10 is required. The first learning and Memory operation defined serial radio coding remains constant. A second learning and storage serves to establish user legitimacy, e.g. So a 6-digit Number, the same applies to 2-wire operation.

Example 4

Again, a changeable memory space in the code lock 10 is needed. By means of a Table and entering a pre-assigned digit sequence can directly use the serial radio signal programmed or generated and set. As with a remote control with Coding switch can now enter a desired code on the sensor keys 14 and save. The user legitimation, e.g. a 6-digit code, in one second save, regardless of the serial line or radio coding.

The practical use is as follows. With the first touch of a any key, the keypad 14 is illuminated on the glass plate 12, e.g. by a light emitting diode 19 feeds light. If no further operation, so switches the lighting will turn off after a set time. About one or more direct acting Sensor keys (14, 26), a function may be controlled, e.g. Yard light. Bell, etc. As an acknowledgment and visual feedback in particular an LED (17) is activated for each actuated key, thus signaling the command recognition. The LED duty cycle corresponds, for example, to the duration of the operation. Alternatively, you can the respective LED (17) remain set until it over time or after total command is switched off. The code lock 10 is thus maximum with the same number LEDs are equipped as buttons are present. The LEDs can spatially the jewelligen Assigned to the sensor key or deliberately discontinued on the contrary, as shown in FIG. 1, so just no visual assignment to the actuated sensor button is possible. Instead of the direct-acting sensor keys, the numeric or symbol field be served in the necessary order. Also here is one each Acknowledgment LED (17) is addressed, as described above.

After the number of digits expected in the receiving device has been entered, e.g. one 6-digit code, can immediately transfer data via the 2-wire line or via Radio. The shutdown occurs after a fixed or adjustable Time. Alternatively, you can provide, after entering the number sequence in addition to consciously operate a start button, the shutdown after releasing or time expires. Is a receiver 24 in the code lock / radio code lock, 10 integrated, so now comes the return information of the previously controlled device. Provided no further operation takes place, the code lock or radio code lock goes after predetermined time with switching off of all LEDs and the lighting in the standby mode. A minimum and maximum operating time prevents in conjunction with a Minimum and maximum pause time, unauthorized switching, e.g. by rain or water drops, beetles, spiders or the like.

Via the data line 23 is a data protocol to a receiving and evaluation device transferable, which switches the connected devices when correctly recognized. A simple connection of the 2-wire wires thus does not lead to a switching operation. For example, open the door. Such a 2-wire evaluation device is not the subject of the invention.

Ex factory, the direct-acting sensor keys 14 with a continuous coding Mistake. This allows multiple code / wireless code locks operate side by side, which act on different objects, e.g. on apartment bells in one Small apartment house. However, if you want a central bell in a single-family home, for example controlled by a plurality of radio code locks 10, the continuous factory code can ever Device can be reprogrammed to a single factory code on all devices.

Each code lock 10 has next to the factory code a general code in the form of a Programmed multi-digit number. After entering this general code is the Code lock 10 memory opened. The hand-held transmitter 11 with known coding, e.g. to operate a yard or garage salary, is now in the vicinity of a few cm away from the code or radio code lock. With it takes over or learn the code / radio code lock 10 by radio transmission (radio frequency), by magnetic coupling (coil) or by optical coupling (infrared, LED, Photodiode and the like) the hand transmitter code and stores it after formal check. In In another store, the user legitimization is programmed, e.g. a 6-digit number, whereby the memory and programming process of the code lock 10 is completed. After entering the correct number combination, i. user legitimacy, sends the code / radio code lock 10 learned from the transmitter 11 serial coding via the 2-wire system and / or radio.

The invention is not limited to one of the above-described embodiments, but variously changeable. The code lock 10 preferably has a glass plate 12, the technique but not in this, but on the inside of the plate in the form of visible Conductor 28, e.g. Copper conductor, assembled SMD construction cell and the like. A plastic housing 15 completes the back of the code lock 10 not in an entrance door or a door handle needs to be integrated, which significantly reduces the installation effort. Without mechanical pressure contact, but only by capacity change Fingerprint can be on the keypad 14 signals generated by line and / or radio or transponders are transmitted.

In general, the code lock 10 is provided with a solid, planar glass plate 12, but this can be replaced by a climate-resistant plastic plate, provided the electrical Functions including lighting are guaranteed. Numerals, company logos And captions can be used in special cases on condition be imprinted or engraved that the recognizability and function of the keypad 14 is not affected. In contrast to interior, back markings such external imprints or engravings do not need to be inverse.

Except for a standard code lock 10 (line connection for example in 2-wire technology) The invention also provides a radio code lock in which the line connection is replaced by a radio transmitter. Further, the combination of a standard code lock with a radio code lock in a device possible and provided, likewise optionally a multi-frequency radio code lock, wherein the transmission frequency e.g. is selected via code input, with or without line connection.

It should be noted that in a preferred embodiment of the invention Codesch! Oß 10 a closed, chemlKallen- and waterproof, flat outer surface 13, a keypad 14 and inner markings 25 such as numbers, symbols, etc, having. A solid flat glass plate 12 has the recognizable from the outside 13 forth Keypad 14 and on its inside a conductor structure 28 and electronic Institutions. The glass plate 12 has self- or luminescent status indicators 17 on and is flat illuminated, in particular by means of laterally or from above einstrahlender Light-emitting diodes 19. The keypad 14 has sensor surfaces 26 for printing on electronic switching by finger rest.

All arising from the claims, the description and the drawing Features and advantages, including design details and spatial arrangements, can be essential to the invention both for themselves and in a wide variety of combinations be.
