Definitions

  • the present invention relates to ball padlocks with interchangeable shackle.
  • a ball lock conventionally comprises a padlock body and a U-shaped shackle, with a long leg received in a bore of the body and a short leg intended to be received in a parallel bore for its locking therein.
  • a set of balls cooperates with housings of a trainer, as well as with housings provided on the legs of the handle, to ensure the locking/unlocking of the legs on the padlock body.
  • a cylinder with rotor and stator makes it possible to turn the trainer in different positions, and in particular in a position where the balls are received in the housings of the trainer, then allowing the unlocking of the padlock.
  • padlocks with interchangeable shackle have already been proposed, making it possible to set up shackles of different dimensions, on the same padlock body.
  • the patent application US2007/0240459 describes another example of a ball padlock with an interchangeable shackle.
  • the padlock described in this patent application is a leaf padlock, without a shackle spring and without a return spring for automatic closing.
  • the shackle can be extracted relative to the padlock body when it is in an angular position at 180° relative to its closed position on the padlock body and the rotor is in its position allowing extraction.
  • a general object of the invention is to provide a ball padlock solution with an interchangeable shackle and cylinder which does not have the drawbacks of the prior art and which is in particular of greater reliability.
  • the secondary pocket is provided on the long leg according to a configuration adapted to allow it to receive the ball in a position of the handle where the latter is, relative to its closed position on the padlock body, pivoted on the axis of said long leg by a given extraction angle which is between 40° and 140°, typically 90°.
  • the padlock further comprises a torsion spring which is arranged on the trainer and ensures the return of the rotor to a neutral position allowing the engagement and disengagement of the key.
  • the 90° position (or more generally a given position between 40° and 140°) is not naturally stable when the open padlock is hung on a support, which further reduces the risk of extraction.
  • the pockets on the long (handle) leg are elongated.
  • the invention also proposes an assembly comprising a padlock of the aforementioned type, as well as at least one handle of a height different from that of the padlock.
  • the padlock illustrated on the figure 1 And 2 comprises a padlock body 1 receiving a padlock lock cylinder 2, as well as a U-shaped handle 3 mounted on the body 1.
  • the body 1 is typically made of brass, treated steel, aluminum, stainless steel or plastic.
  • the lock cylinder 2 comprises a rotor 2a, a stator 2b, as well as a set 2c of pistons, counter-pistons and springs.
  • a key (not shown) ensures the alignment of the pistons and counter-pistons in the corresponding housings of the rotor 2a and of the stator 2b and makes it possible to rotate said rotor 2a in the stator 2b to unlock the padlock.
  • the rotor 2a is capped, at its end opposite that receiving the key, by a driver 6 which is mounted integral in rotation with said rotor 2a and rotates with the latter.
  • Said trainer 6 is generally cylindrical in shape. It comprises a housing coaxial with the rotor, which receives a torsion spring 7 engaged on one side on the padlock body 1 and on the other on the driver 6. Said spring 7 exerts on the driver 6 a force tending to return the rotor 2a to a neutral position allowing the engagement/disengagement of the key in said rotor 2a.
  • the U-shaped handle 3 has a long leg 3a and a short leg 3b.
  • the long leg 3a is engaged coaxially - with a helical spring 5 of the handle - in a complementary bore 4a of the padlock body 1.
  • the function of this helical spring 5 is to push the U-shaped handle 3 upwards, when the handle U is unlocked.
  • the padlock body 1 also comprises a second bore 4b intended to coaxially receive the short leg 3b in the locking position of the U-shaped shackle on the padlock.
  • the bore 4b also receives a long screw 15 which cooperates with a complementary threading of a plate 16, which closes the bottom of the padlock body 1 and holds the cylinder 2 in place therein.
  • Cylinder 2 can thus be changed by screwing/unscrewing screw 15 on body 1.
  • the leg 3a of the handle 3 has a circumferential groove 8, open radially outwards.
  • the legs 3a and 3b and the trainer 6 further comprise different pockets intended to cooperate with a set of two balls 12a, 12b, to perform different functions when handling the padlock.
  • the short leg 3b comprises, in the immediate vicinity of its end opposite the bottom of the U, a hemispherical pocket 9 which is open radially outwards and faces the leg 3a.
  • the trainer 6 comprises two diametrically opposed hemispherical pockets 13a, 13b, which are at the same level as the balls 12a, 12b and are intended to be opposite the bores 4a, 4b, when the rotor 2a is turned 90 ° relative to its neutral position where the key can be engaged in said rotor 2a.
  • the open state is obtained by turning the key and the rotor by 90°.
  • the balls 12a, 12b slide on the walls of the trainer 6 and are housed in the pockets 13a and 13b.
  • the short leg 3b can be disengaged from its bore 4b, while the ball 12a slides along the pocket 10a, until it is blocked by the cooperation of the ball 12a and the groove 8 which it has at its foot ( figures 4a and 4b ).
  • the long leg 3a further comprises a second notch 11 ( figure 1 ).
  • This also comprises a hemispherical pocket 11a and a flat 11b which extends from the bottom of said pocket 11a, towards the circumferential groove 8.
  • the pocket 11a is located at a level of the leg 3a between the level of the pocket 10a and the termination groove 8, being close to the aforementioned level of said pocket 10a.
  • the flat 11b is perpendicular to the flat 11a.
  • the trainer 6 has an additional pocket 14 ( figures 4a, 4b and following) located at the cylindrical periphery of said trainer 6, between the two pockets 13a, 13b, typically close to pocket 13a which receives ball 12a, with an offset of 35° of its angular position on the cylinder of trainer 6, relative to the position of pocket 13a on said trainer 6 .
  • the disengagement of handle 3 occurs as follows.
  • the key being turned 90°, the handle 3 which passes into the out position of the body 1 is itself turned by the user around the axis of the long leg 3a, in order to position the handle 3 in its position extraction.
  • This extraction position forms a given angle of between 40° and 140° with respect to the closed position of the shackle 3 on the padlock body. Typically, it is at 90°.
  • the balls 12a, 12b remain in place in the pockets 13a, 13b of the trainer 6.
  • the secondary pocket 11 is then positioned opposite the ball 12a ( figures 5a and 5b ).
  • the key is then placed in the initial position so that the driver 6 returns to the neutral position with the rotor 2a, under the effect of the torsion spring 7.
  • the ball 12a is then pushed back by the peripheral wall of the driver 6 into the secondary pocket 11 ( Figures 6a and 6b ), during the insertion phase of the long leg 3a in the bore 4a.
  • the key is operated to turn the rotor 2a and the driver 6 through an angle of 35°.
  • the complementary pocket 14 of the trainer 6 is then positioned opposite the ball 12a.
  • the spring 5 pushes the handle 3 relative to the body 1 of the padlock, the end of the leg 3a of the handle 3 (under the groove 8) pushes the ball 12a into the pocket 14.
  • the leg 3a can then s extract from its bore ( Figures 7a and 7b ).
  • the user can then close the new handle 3 on the body 1.
  • the balls 12a and 12b are repositioned in the pockets 9 and 10a to ensure the locking of the padlock ( Picture 10 ).
  • the padlock can be marketed as a set comprising said padlock and a set of shackles of different dimensions.
