[0001] This invention relates to a radial tumbler lock and key (sometimes known as an axial tumbler pin lock and key).
[0002] Known radial pin tumbler lock and keys are provided with cylindrical mating configurations. However, such locks can be prone to picking.
[0003] According to the present invention, there is provided a radial pin tumbler lock and key, the mating configuration of the key being provided by a hollow body open at one end and the key having axial cuts arranged around the external surface of the open end of the hollow body to mate with pins of the lock; characterised in that the lock and key each have a non-cylindrical, substantially regular polygonal mating configuration extending parallel to the direction of insertion of the key in the lock, the polygonal mating configuration of the key being provided inside the body and extending longitudinally thereof, and the mating configuration of the lock being provided by a polygonal upstanding post, the post being dimensioned to mate inside the body of the key.
[0005] The exterior of the cylindrical body can be provided with one or more radially-outwardly extending ribs running longitudinally of the cylindrical body, the ribs being insertable through appropriately-located grooves in the lock.
[0007] The free end of the post can be provided with a chamfer to ease insertion of the key into the lock.
[0008] For a better understanding of the invention and to show how it may be carried into effect, reference will now be made by way of example, to the accompanying drawings, in which:-
Figure 1 is a perspective view of a key for a radial pin tumbler lock,
Figure 2 is a side view of the key shown in Figure 1,
Figure 3 is a perspective view of the radial pin tumbler lock, and
Figure 4 is a plan view of the radial pin tumbler lock.
[0009] Figures 1 and 2 show a key 1 having a body portion 2 of cylindrical external configuration and an octagonal internal configuration 2A having an open end 2B for insertion in the lock. The body 2 is joined to a key bow 3 and is provided with two radially-outwardly extending ribs 4 running longitudinally of the body 2.
[0010] Radially of the body 2 are provided a plurality of axial cuts (not shown) arranged around the external surface of the open end of the body 2, the cuts being of different axial lengths and spacings to provide different key combinations with the lock.
[0011] The key 1 is designed to be inserted into a mating hole (not shown) in a radial pin lock core 5 of the lock 6, shown in Figures 3 and 4.
[0012] The lock 6 is provided with a central up-standing post 7, whose free end is chamfered. The post 7 is provided with an external, possibly regular octagonal configuration to match that of the inside of the key 1. Surrounding the post 7 is an annular space with a substantially circular outer diameter, this space defining the core 5 and being so dimensioned to receive the cylindrical body 2 and rib 4, 4A of the key 1. To accommodate the rib 4, 4A, one or.more corresponding grooves 8 are provided in the cylindrical wall 9 defining the outer diameter of the core 5.
1. A radial pin tumbler lock (6) and key (1), the mating configuration of the key (1)
being provided by a hollow body (2) open at one end and the key having axial cuts
arranged around the external surface of the open end of the hollow body (2) to mate
with pins of the lock; characterised in that the lock and key each have a non-cylindrical, substantially regular polygonal mating
configuration extending parallel to the direction of insertion of the key in the lock,
the polygonal mating configuration (2A) of the key (1) being provided inside the body
and extending longitudinally thereof, and the mating configuration of the lock (6)
being provided by a polygonal upstanding post (7), the post being dimensioned to mate
inside the body of the key.
2. A lock and key according to claim 1, wherein the polygon is that of an octagon.
3. A lock and key according to claim 1 or 2, wherein the radial pin tumbler lock is provided
with pins to engage mating radially spaced cuts of the key.
4. A lock and key according to claim 1, 2 or 3, wherein the exterior of the cylindrical
body of the key is provided with one or more radially-outwardly extending ribs (4,
4A) running longitudinally of the cylindrical body, the ribs being insertable through
appropriately-located grooves (8) in the lock.
5. A lock and key according to any one of the preceding claims, wherein the free end
of the post (7) is provided with a chamfer to ease insertion of the key into the lock.
1. Schloss (6) mit radial angeordneten Stiftzuhaltungen und Schlüssel (1), bei denen
die Passungsstruktur des Schlüssels (1) durch einen Hohlkörper (2) bereitgestellt
ist, der an einem Ende offen ist, und der Schlüssel zur Passung mit Stiften des Schlosses
axiale Einschnitte aufweist, die um die äußere Fläche des offenen Endes des Hohlkörpers
(2) angeordnet sind, dadurch gekennzeichnet, dass das Schloss und der Schlüssel jeweils eine nicht zylindrische, im Wesentlichen gleichmäßig
polygonale Passungsstruktur aufweisen, die sich parallel zu der Einführrichtung des
Schlüssels in das Schloss erstreckt, wobei die polygonale Passungsstruktur (2A) des
Schlüssels (1) in dem Körper bereitgestellt ist und sich in dessen Längsrichtung erstreckt
und die Passungsstruktur des Schlosses (6) durch einen polygonalen aufrecht stehenden
Ständer (7) bereitgestellt ist, wobei der Ständer dimensioniert ist, um in den Körpers
des Schlüssels zu passen.
