Claims33
A locking device comprising an outer housing member and an inner core, said inner core being receivable within said outer housing, said inner core comprising:
- (a) at least one locking element comprising at least one projection;
- and
- (b) at least one receiving portion for receiving said at least one locking element;
- wherein said at least one projection extends radially outwards from said inner core and said receiving portion;
- said outer housing member comprising an internal face comprising:
- (c) at least one axial channel;
- and
- (d) at least one annular channel;
- each channel being able to receive said at least one projection of said at least one locking element.
A key for use with a locking device, the locking device comprising an outer housing member and an inner core, said inner core being receivable within said outer housing, said inner core comprising:
- (a) at least one locking element comprising at least one projection;
- and
- (b) at least one receiving portion for receiving said at least one locking element;
- wherein said at least one projection extends radially outwards from said inner core and said receiving portion;
- said outer housing member comprising an internal face comprising:
- (c) at least one axial channel;
- and
- (d) at least one annular channel;
- each channel being able to receive said at least one projection of said at least one locking element.
A lock and key combination, comprising:
- a locking device, the locking device comprising an outer housing member and an inner core, said inner core being receivable within said outer housing, said inner core comprising:
- (a) at least one locking element comprising at least one projection;
- and
- (b) at least one receiving portion for receiving said at least one locking element;
- wherein said at least one projection extends radially outwards from said inner core and said receiving portion;
- said outer housing member comprising an internal face comprising:
- (c) at least one axial channel;
- (d) at least one annular channel;
- each channel being able to receive said at least one projection of said at least one locking element;
- and
- a key for use with the locking device.
Use of a locking device and key, wherein the key is brought into contact with the locking device, the locking device comprising an outer housing member and an inner core, said inner core being receivable within said outer housing, said inner core comprising:
- (a) at least one locking element comprising at least one projection;
- and
- (b) at least one receiving portion for receiving said at least one locking element;
- wherein said at least one projection extends radially outwards from said inner core and said receiving portion;
- said outer housing member comprising an internal face comprising:
- (c) at least one axial channel;
- (d) at least one annular channel;
- each channel being able to receive said at least one projection of said at least one locking element;
- and
- wherein pressure is exerted on the at least one locking element of the inner core by the actuating portion of the key to urge the locking elements of the device towards the distal end of the inner core, wherein when the key reaches a predetermined position the projections of the locking elements are aligned with each other and with an annular groove in the outer housing, and wherein the key is then rotated, thereby rotating the inner core.
