Abstract
A radial pin tumbler lock (6, Fig 3) and key (1) in which both have a non-cylindrical substantially rectangular polygonal eg octagon mating configuration extending parallel to the direction of insertion of the key into the lock. The key (1) has a hollow body with an octagonal internal configuration (2A); The mating configuration of the lock is then an octagonal upstanding post (7).
Description
RADIAL PIN TUMBLER LOCK AND KEY
This invention relates to a radial tumbler lock and key
(sometimes known as an axial tumbler pin lock and key).
Known radial pin tumbler lock and keys are provided with cylindrical mating configurations. However, such locks can be prone to picking.
According to the present invention, there is provided a radial pin tumbler lock and key, wherein 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 polygon maybe that of an octagon.
Preferably, the radial pin tumbler lock is provided with pins to engage mating radially displaced cuts of the key.
In the case of the key, its mating configuration can be provided by a hollow cylindrical body open at one end with the polygonal mating configuration being provided inside the body and extending longitudinally thereof.
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.
The key can be provided with a key bow.
The mating configuration of the lock can be provided by a polygonal upstanding post, the post being dimensioned to mate inside the body of the key. The free end of the post can be provided with a chamfer to ease insertion of the key into the lock.
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.
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.
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.
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.
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.
Claims (7)
1. The radial pin tumbler lock and key wherein 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.
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 mating configuration of the key is provided by a hollow cylindrical body open at one end with the polygonal mating configuration being provided inside the body and extending longitudinally thereof.
5. A lock and key according to claim 4, wherein the exterior of the cylindrical body of the key is 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.
6. A lock and key according to any one of the preceding claims, wherein the mating configuration of the lock is provided by a polygonal upstanding post, the post being dimensioned to mate inside the body of the key.
7. A lock and key according to claim 6, wherein the free end of the post is provided with a chamfer to ease insertion of the key into the lock.
