Definitions
- the invention relates to a key shank for a motor vehicle key, wherein the key shank at least two side surfaces, in particular two
- Wide side surfaces which are arranged opposite to each other and are arranged separated from each other by at least one narrow side surface.
- Reversible key is usable.
- the key shank In order to mill the coding path in the key shank, the key shank requires a sufficiently large width
- Narrow sides of at least 3 mm This results in a larger space for a housing of a motor vehicle key, in which the key shank is used or connected. As a result, this leads to a larger one
- Car key which can be stowed worse and has a small number of codes.
- Coding tracks are provided which are different from each other and a second broad side surface has a flat and uncoded surface. This advantageous embodiment of the key shank ensures that the
- Key shaft has a compact design and at the same time the number of codes is increased, whereby the security of a locking system, especially for motor vehicles, is improved.
- the key shank according to the invention only one broadside surface has to be milled. This can be the width of the
- a first coding is at least partially formed asymmetrically to a second coding, wherein the first coding and the second coding on the first broadside of the
- Closing system can be improved. Also, this is the compact
- the key shaft is formed when the
- Narrow side surface comprises, each having at most a width b of 1, 8 mm.
- This width b of 1, 8 mm can only be guaranteed if only on a broad side surface of the key shaft a milling for the production of Codierbahnen is performed.
- the second broad side surface of the key shank is formed with a, in particular smooth and flat, plane, it is possible to dispense with further material for this broad side surface, which is required in the prior art for milling further coding webs.
- the width b of the narrow side surface is the highest 1, 8 mm, thus, a housing of the motor vehicle key, in which the key shank is mounted and arranged, can be made smaller and more compact.
- a sufficiently high number of codes by means of the coding tracks and a compact design of the key shank can be achieved if at least one broadside surface has at most a width B of 7.8 mm.
- Lock system can provide, without affecting the compactness of the key shaft negative.
- the key shank can be arranged when the key shank is arranged in a housing of the motor vehicle key.
- the housing can serve as a gripping element to operate the key shank.
- the key shank is designed as an emergency key.
- Emergency keys must have the property that they are designed small and compact in size, because they are used only in an emergency when an operation of the vehicle key, which is designed in particular as a radio remote control, for example, due to an empty battery is excluded.
- the emergency key is therefore only used in very rare cases. Therefore, it may be appropriate if the key shank has a compact construction in its capacity as an emergency key.
- the key shank has a compact construction in its capacity as an emergency key.
- the motor vehicle key is designed as a card and the key shaft is arranged within the card. Because of the compact design of the key shank this can be arranged very safely and easily in a map, because
- Narrow sides of the card must not have more than 2.3 mm to this
- the key shank according to the invention is outstandingly suitable for arranging this in a card designed as a motor vehicle key.
- the card itself may be provided with electronics, which grants the user access to the motor vehicle as part of a keyless entry system.
- use of the key shank is usually necessary only in an emergency, if the card remains inoperative, for example because of an empty one
- the key shank can be used as an emergency key, and as described above, the goal is to make an emergency key as small as possible without the safety of
- inventive key shank are arranged in said card advantageously in said manner.
- the life of the key shaft can be increased if the
- Key shank has a copper-nickel-zinc alloy.
- rusting of the key shaft is advantageously prevented.
- a motor vehicle key is protected, which a
- Figure 1 shows a key shank according to the invention, which with a
- Car key is connected in a view from above, and
- FIG 2 shows the key shank according to the invention, which with the
- Motor vehicle key is connected in a view from below, and
- FIG. 3 shows the key shank according to the invention, which with the
- Car key is connected in a perspective view.
- FIGS. 1 to 3 a key shank 1 according to the invention designed for a motor vehicle key 2 from a copper-nickel-zinc alloy is visualized.
- the motor vehicle key 2 has a key head 3 with a, in particular two-part, housing 4 with a first housing section 5 and a second housing section 6, which is firmly connected to the key shank 1.
- Motor vehicle key 2 is arranged, wherein the key shank 1 is injected into the housing 4 of the key head 3. It is also conceivable, the
- Grip key shaft 1 with the housing and / or the key shank 1 non-positively and / or positively in the housing 4, insert.
- Key shank 1 and an electronic unit not shown in detail is used. Furthermore, at least two push buttons 7, 8 are arranged within the housing 4, wherein the first push button 7 is used to open the motor vehicle and the second push button 8 is used to close the motor vehicle.
- the key shank 1 has two side surfaces, a first one
- the key shaft 1 present here comprises three narrow side surfaces, namely a first longitudinal narrow side surface 1 1, a front side narrow side surface 12 and another not shown in detail second longitudinal narrow side surface, which substantially like the first
- Narrow side surface 1 1 is formed. All narrow side surfaces have the same width b of about 1, 8 mm.
- Wide side surface 10 are through the aforementioned narrow side surfaces
- a first encoder track 13 is at least partially formed asymmetrically to a second encoder track 14, wherein the first encoder track 13 and the second encoder track 14 on the first
- the Broad side surface 9 of the key shaft 1 are arranged.
- the first coding path 13 arranged on the first broadside surface 9 and the second coding path 14 likewise arranged on the first broadside surface 9 are consequently designed differently from one another.
- the coding tracks 13, 14 can in principle be of any desired design and consequently have any number of codes within the scope of the dimensions of the key shaft 1. However, it should be prevented that the encoder tracks 13, 14 are formed symmetrically to each other, because then the number of codes of the locking system is reduced.
- the second broad side surface 10 has a flat and uncoded surface 15.
- the width b of the key shank 1 can be considerably reduced, because a milling for forming further coding paths on the second broad side surface 10 can advantageously be dispensed with.
- the key shank 1 can also serve as an emergency key for a motor vehicle key 2 of a keyless entry system designed as a passive radio remote control. Then the key shank 1 can be arranged completely in the housing 4 of the motor vehicle key 2. Due to the compact key shank 1, in particular because of the small dimensions of the key shank 1, the key shank 1 can also be arranged as an emergency key within a motor vehicle key 2 designed as a card. The key shank 1 is then placed inside the card or alternatively may form a portion of the side wall of the card. This allows the card to be made flat and compact, so that it can be easily accommodated in a wallet. At the same time a secure locking system for the motor vehicle can be ensured because of the emergency key due to the two provided Codierbahnen 13, 14 on the first broadside surface 9 a
- the key shank 1 in particular the key shank 1 of the emergency key, has a width B of the broad side surface 9, 10 of 7.8 mm, a width b of the narrow side surface of 1, 8 mm and preferably a length L of 18.7 mm.
