Definitions
- the present invention relates to an improved padlock.
- Existing padlocks are substantially made as shown in figure 1 having a hardened locking arm 1 with a brass body
- the locking arm is axially moveable within a bore 4 and is lockingly held in a second bore 5 by a locking bolt 6 which is released by a key operated tumbler 7.
- the lock can be destroyed by the body of the lock being - gripped in a spanner or like tool along its long sides and the lock twisted rupturing the walls of the lock at 3 and/or 3' .
- the present invention seeks to ameliorate this problem by providing a padlock which has a body substantially cylindrical in shape with a rotatable outer annular covering enclosing the cylindrical wall of the body.
- Figure 2 is a perspective view of a schematic representation of one embodiment of the present invention.
- Figure 3 is a cross-sectional view through figure 2.
- the body 8 of the lock is cylindrical in shape.
- the areas of weakness 3 and 3' still remain.
- a rotatable outer layer 9 encloses the padlock body.
- This rotatable outer layer 9 is preferably mounted on two races 10 and 11 of ball bearings with top and bottom seals 12. The outer layer can extend over the top of the body or the top and the bottom of the body as shown in figure 3 so as to add extra protection to the lock.

Abstract
Un cadenas améliore la protection contre la rupture du cylindre du cadenas. Le corps du cadenas (8) possède une forme cylindrique et une enveloppe externe rotative (9) de manière à empêcher l'application de toute force de torsion sur la section du corps (8) contenant le pêne de verrouillage (6).A padlock improves protection against rupture of the padlock cylinder. The body of the padlock (8) has a cylindrical shape and a rotary outer casing (9) so as to prevent the application of any torsional force to the section of the body (8) containing the locking bolt (6).
