Abstract

The invention relates to a flat key with a handle part (2) and a key bit (3), the handle part (2) comprising a housing (5) and the key bit (3) being pivotable on the handle part housing (5) from a folded position to a folded position. is arranged. In order to ensure that the handle part housing (5) of the flat key (1) can be kept small and yet there is sufficient space for any electronics that may need to be accommodated, the invention proposes that the key bit (3) in its retracted position in an outside recess ( 12) to accommodate a first flat side (13) of the housing (5) and to arrange it on the handle part housing (5) in such a way that it can be pivoted into the unfolded position about an axis of rotation (10) extending in the direction of the broad side of the handle part housing (5). <IMAGE>

Description

The invention relates to a flat key with a handle part and a key bit, the handle part being a housing includes and the key bit from a folded into a unfolded position pivotable on the handle part housing is arranged.

Such flat keys are known and have the advantage on that they take up relatively little space and that with their Wear, e.g. in a coat or trouser pocket, a smaller one There is a risk of injury as with flat keys key bit rigidly attached to the handle.

Usually used in the known generic flat keys the key bit after pressing a button via a torsion spring on the side of the handle section housing folded out or against the pressure of the torsion spring in the Handle housing swiveled in.

The disadvantage of these known flat keys is below other that for the accommodation of the key bit in the respective handle part housing requires a relatively large amount of space.

This is particularly important with electronic keys but needed for the electronic circuit elements to keep the corresponding handle part housing as small as possible. In addition, in the known folding keys Handle part central position of the key bit in its unfolded position can only be reached by complex measures.

The invention has for its object a flat key to specify the type mentioned, the handle part housing can be kept small and still sufficient Has space for any electronics to be accommodated.

This object is achieved by the features of Claim 1 solved. Further, particularly advantageous configurations the invention disclose the subclaims.

The invention is essentially based on the idea that Key bit in its folded position in one to accommodate the outside recess of the flat side of the housing and to be arranged on the handle part housing such that he around in the direction of the broad side of the handle part housing extending axis of rotation into the extended position is pivotable.

In order to optimally adapt the mechanical parts to the available ones Adapt space of the handle part housing, it has proven to be proven advantageous, the key bit in the direction of the axis of rotation slidably to arrange and a positive guidance for the Key bit must be provided such that the key bit in the folded position on the edge side in the handle part housing stored and centered in the extended position is arranged on the handle part.

In a further advantageous embodiment of the invention are the mechanical parts of the flat key, in particular so the key bit with storage and torsion spring as well as the forced guidance of the key bit and the locking device, in a separate mechanical function carrier arranged. This can be laterally in the handle housing push in and connect with it (e.g. snap). With such a separately mountable function carrier is a particularly quick assembly of the flat key and an optimal storage of the to be assembled Units possible.

To simple assembly or disassembly of the invention To be able to make a flat key, it has also proven to be Proven useful if the handle housing from two together connectable (e.g. clippable) bowl-shaped Halves of the housing.

Further details and advantages of the invention result from the following exemplary embodiment explained with reference to figures. Show it:

Fig. 1
a plan view of a flat key according to the invention, partially shown in section, with the key bit folded in and
Fig. 2
1 corresponding top view with the key bit extended.

1 and 2, 1 denotes a flat key, which comprises a handle part 2 and a key bit 3. The Key bit 3 is in an interchangeable function carrier 4 arranged, which in the handle housing 5 of the Flat key 1 can be inserted and locked with this.

The handle part housing 5 consists of two clips that can be clipped together shell-shaped housing halves 6, 7 made of plastic and encloses the corresponding for an electronic key electronic circuit elements.

The key bit 3 is in a folded position (Fig.1) can be pivoted into an extended position (Fig.2) arranged on the function carrier 4. This is the key bit 3 attached to a shaft 8 which is transverse to one to the longitudinal axis 9 of the key bit 3 in the direction of the broadside of the grip part housing 5 extending axis of rotation 10 is pivotable. The key bit 3 is one in his in the folded position biased torsion spring 11, such that the key bit 3 after its unlocking from the torsion spring 11 in the extended position is pivoted.

In addition, the shaft 8 and thus the key bit 3 in Direction of the axis of rotation 10 slidably arranged, the Torsion spring 11 also acts as a compression spring.

The key bit 3 is in its folded position in a depression 12 (FIG. 2) of the first (facing the viewer) Flat side 13 of the casing of the handle part housing 5 stored and in this position by a likewise on the Function carrier 4 arranged locking device 14 fixed. For this purpose, the locking device 14 comprises one by a compression spring 15 acted slider 16, the is pressed by the spring 15 over the key bit 3.

If the slider 16 is pushed back, the key bit becomes 3 pivoted about the axis of rotation 10 by the torsion spring 11 and thereby by one located on the function carrier 4 Forced guidance 17 laterally opposite the folded position moved, in such a way that the key bit 3 in its unfolded position centrally on the handle part 2 is arranged.

In the unfolded end position, the key bit 3 presses against a stop 18 and is in this position one on the slide 16 of the locking device 14 arranged locking cam 19, which is in a groove-shaped Recess 20 engages the shaft 8 and there against a Locking surface 21 is pressed, secured.

Of course, the invention is not based on the above described embodiment limited. For example the key bit also with a sleeve-shaped Part connected, which is around a fixed shaft pivoted and slidably disposed along this shaft is.
