Definitions

the innovation relates to a key, in particular for a lock cylinder, comprising a key handle and a key shaft connected to it in one piece, at least the key handle being made from a flat metal material blank.
a disadvantage of this known embodiment is that the volume and in particular the ability to arrange the keys within a keychain is adversely changed by the synthetic resin pads.
the innovation is based on the object of specifying a key that is ergonomically inexpensive to handle, without the volume of the individual key and without the volume of a keychain formed from individual keys increasing.
the key handle is asymmetrical with respect to a central plane perpendicular to its main plane and parallel to the longitudinal axis of the key shaft.
Markings can be created, for example, by undulating the concave edge.
markings are conceivable, e.g. B. markings in other edge areas of the key handle or markings by different location of the holes provided for the passage of a key ring.
the remaining boundary edges of the key shaft are essentially straight and rectangular, parallel or perpendicular to the key shaft axis are arranged.
the corners can be more or less rounded, and the radius of curvature of the corners can also be used for marking.
the key have a greater height in its main plane perpendicular to the key shaft axis than the key shaft. It is recommended that the key handle protrudes in its main plane perpendicular to the key shaft axis over the key chest and the key back. With this latter measure, an approximate symmetry of the overall key is achieved and thus a prerequisite for a small space requirement of a bunch of keys composed of several keys according to the innovation.
the envelope of the outline of the key handle be substantially rectangular, preferably substantially square, a shape that can be easily connected to the concave edge chosen for ergonomic reasons.
the innovation idea is particularly applicable to keys in which the entire key - both the key handle and the key shaft - are formed from a flat sheet metal blank.
the new spatial shape can also be used where the key shaft and key handle are assembled for manufacturing reasons, for example a flat key handle with a key shaft that is round in cross section.
non-ferrous metal sheets and steel sheets have essentially been used for the production of flat keys.
a security key made of a gold-platinum Make alloy has become known from DE-GM 82 36 193, a security key made of a gold-platinum Make alloy.
the known keys - insofar as they are made of non-ferrous metal or steel - have the disadvantage of a relatively high weight, which is particularly important for larger key rings.
keys made of non-ferrous metal and gold-platinum alloy have the disadvantage that relatively rapid wear of the tumbler edges and any guide grooves that may be present must be expected.
Gold-platinum alloy keys have the disadvantage of very high costs and are therefore unsuitable in the majority of applications, particularly in locking systems.
the innovation is therefore based on the task of specifying a key that is relatively light in weight, ensures a long service life and is relatively inexpensive to manufacture.
the entire key is made of titanium sheet or an alloy sheet with a high titanium content.
Such flat keys made of titanium sheet are characterized by great hardness and thus a long service life. Compared to steel, non-ferrous metal and gold-platinum alloy keys, they are relatively light and inexpensive.
the accompanying figure explains the innovation using an exemplary embodiment.
the figure shows a lock cylinder 10 of a conventional type and a key 12 with a key shaft 14 and a key handle 16.
Key shaft 14 and key handle 16 are stamped in one piece from titanium sheet.
the key shaft points a back 14a and a key chest 14b and guide grooves 14c.
the guide grooves 14c are dimensioned for engagement with guide ribs in the key channel 10a of the lock cylinder.
the key chest 14b is serrated, the serrations being used to control the usual pin tumblers. Elevations and / or preferably depressions 14d can also be provided in the side surfaces of the key shaft for controlling additional locking pins of a known type.
the key handle 16 has an outline which is rectangular in shape with edges 16a, 16b, 16c and 16d. The transitions of the edges are rounded, as can be seen at 16e.
the boundary edge 16c is concave.
the user grasps the key handle with its side surfaces between the thumb and index finger of one hand, so that the middle finger comes to rest on the concave boundary edge 16d.
the curvature of the concave boundary edge 16c therefore adapts well to the circumferential curvature of the middle finger.
the middle finger can rest against the concave boundary edge 16c over a relatively large length, so that a low surface pressure is established. Therefore, it is also possible to feel tactile markings on the concave boundary edge, e.g. B. to attach cams 16f.
the boundary edge 16c is the edge which is aligned with the key face 14b of the key shaft 14.
a hole 16g is provided in the key handle 16, which is used to line up the key on a keychain. It can be seen that the key handle protrudes upwards and downwards approximately equally over the key back 14a or the key chest 14b. This is a particularly favorable form, in particular in connection with a position of the hole 16g approximately in alignment with the axis of the key shaft. The keys then hang out on a keychain in an optimal way.
the production of the key from titanium sheet achieves a considerable weight reduction, which is particularly noticeable when several keys are combined to form a key ring.
the hardness of the titanium sheet is so great that a small wall thickness of the key is sufficient without the risk of premature wear.
the wall thickness of the key is, however, limited with regard to the guide grooves 14c. There is also a limit to the reduction in wall thickness with regard to the risk of pain or injury from the edges.
a key ring through hole is provided approximately in the area of the central parallels of the rectangular, in particular square, contour parallel to the shaft axis near an edge remote from the key shaft.
