Definitions

  • This invention relates to padlocks and accessories therefor.
  • Padlocks are widely used for security purposes.
  • padlocks have a shackle which is substantially "u"-shaped and movable in a body between a locked condition and an unlocked condition.
  • the locked condition the shackle and the body for a closed loop while in the unlocked condition the shackle has at least one free end which can be inserted through a staple.
  • one end of the shackle is usually held rotatably secured in the body.
  • Padlocks suffer the disadvantage that they usually can be fairly easily broken. Typical methods of breaking padlocks include the use of a bolt cutter to sever the shackle, twisting the shackle and the body in opposite directions by use of wrenches or levering the body away from the shackle. Further methods include forcing the body away from the shackle by means of a winch or jack or by means of a punch and hammer.
  • One device employs a cover over the whole of the padlock to prevent access to the staple with a bolt cutter. This method does not, however, prevent the body from being pulled away from the shackle.
  • Another device provides a core which is mounted between the shackle and body of a padlock to leave only a portion of the shackle available to receive a staple. This type of device, however, does not prevent the padlock being destroyed when a punch is placed on the core and struck with a hammer to move the base of the padlock away from the shackle. This reliedevice is also inconvenient as it can fall away from the shackle when the shackle is in the unlocked position.
  • Another type of padlock employs flanges extending from the body-of the padlock to protect the shackle. Again, these padlocks provide only limited protection against bolt cutters and punching.
  • a padlock comprising a body and a shackle having a pair of parallel pins at least the ends of which are selectively securable in the body, and a shield from which the pins extend and shaped to provide limited exposure of the shackle.
  • the shackle is a substantially
  • the shield to project partway over the body when the shackle is in a locked condition; for the shield to be formed by a pair of plates secured on opposite sides of the elongate member; for the plates to be secured together by means of a bolt passing through an aperture in one plate and received in a complementary socket in a lug on the other plate; and for the head of the bolt to be severable from the shank of the bolt.
  • the shield is integral with the shackle and forms a solid body.
  • a recess to be formed between the shackle and body with the shackle in a locked condition and for a pin to extend within the recess; and for the shackle to be transversely of similar cross-sectional shape to the body.
  • the padlock to have at least one spacer slidably receivable on a pin to further limit exposure of the pin. Still further features of the invention provide for the padlock to have a cover fitted over the body to limit exposure of the body.
  • cover to have apertures therein through which the pins of the shackle can extend; and for the cover to have an aperture therein through which a key can be inserted into a keyhole in the body to operate the padlock.
  • the bolt to have a slot for locating over a locking pin wherein the locking pin is a snug fit in the slot; and for the cross-sectional diameter of one pin to be greater than that of the other pin.
  • the invention also provides a shield for a shackle substantially as defined above.
  • the invention further provides a cover for a body substantially as defined above.

  • Figure 13 is a part-sectional side elevation of a padlock and padlock accessory according to a sixth embodiment.
  • Figure 14 is a sectional side elevation of the padlock accessory in Figure 13.
  • a first embodiment of a padlock (1) is shown in Figures 1 to 3 and has a body (3) and a shackle (4) which is formed by a cross-sectionally round elongate member of "u"-shape.
  • the shackle (4) thus has a pair of parallel pins (5,6) with one pin (6) being rotatably secured in the body (3), with the shackle (4) in an unlocked condition and the other pin (5) being selectively securable in a socket (not shown) in the body (3) in conventional manner.
  • a shield (7) is provided which is secured to the shackle (4) and shaped to provide limited exposure of the pins (5,6).
  • the shield has a first plate (8) and a second plate (9) which are secured to either side of the shackle (4).
  • the plates (8,9) are arch-shaped to conform to the shape of the shackle and have a stepped shoulder (10) to leave part of the pin (5) exposed.
  • the plates (8,9) are secured together on either side of the shackte (4) by a bolt having a screw threaded shank (16).
  • the shank (16) has a radially enlarged portion (17) partway up its length and a head (18) extending from the enlarged portion (17).
  • the shank (16) passes through an aperture (19) in the first plate (8) and is received in a complementary threaded socket (20) in a lug (21) on the inner surface of the second plate (9).
  • the lug (21) extends partway up the length of the inner surface of the second plate (9) to abut the shackle (4) at its point of curvature and so hinder movement of the plates (8,9) up the shackle (4).
  • the shield (7) limits exposure of the shackle (4) and so assists in preventing the shackle (4) being cut by a bolt cutter (not shown).
  • the shield (7) also reduces the surface area of the padlock available for using a punch (not shown) or other device for forcing the shackle (4) away from the body (3) as the plates (8,9) terminate adjacent the body (3) when the shackle (4) is in a locked condition.
  • FIG. 4 A second embodiment of a padlock shield (30) is shown in Figures 4 to 6.
  • the shield (30) has a first plate (31) and a second plate (32) secured to either side of a shackle (4) of a padlock (1) by a bolt (33).
  • the second plate (32) has a normally projecting peripheral flange (34) which abuts against the outer circumference of the first plate (31) to enclose the shackle (4).
  • the first plate (31) and second plate (32) each have a downwardly projecting ⁇ apron (35,36) which extends partway over the upper surface (37) of the body (3) of the padlock (1) when the shackle (4) is in the locked condition (as shown).
  • the aprons (34,35) terminate above the surface (37) to allow the shackle (4) to be rotatable in the body (3).
  • the enlarged portion (38) on the shank (39) of the bolt (33) is received in a rebate (40) in the first plate (31). With the head (41) of the bolt (33) severed from the shank (39), it is difficult to tamper with the enlarged portion (38) of the bolt (33).
  • the plates (31,32) have a stepped shoulder
  • the shield (30) in this embodiment, provides very limited exposure of the shackle while the aprons (35,36) assist in preventing the padlock (1) from being destroyed by twisting the body (3) in an opposite direction to the shackle (4).
  • a third embodiment of a padlock (50) is shown in Figures 7 to 9.
  • the shackle (51) is integral with a shield and forms a solid body with a pair of parallel pins (52,53) extending therefrom.
  • the shackle (51) is cross-sectionally rectangular and has a stepped shoulder (54) extending partway along its length from which the pin (52) extends.
  • the pin (53) is rotatably secured in the body (55) of the padlock (50) with the pin (53) selectively securable in the body (55) in conventional manner.
  • the lower surface (56) of the shackle (51) is adjacent to the upper surface (57) of the body (55) with a recess being formed between the upper surface (57) and the shoulder (54).
  • the recess permits a shackle (not shown) to be secured about the pin (52).
  • An annular spacer (58) is slidably received on the pin (52). The spacer (58) abuts, in use, a staple (not shown) so that the staple is a snug fit between the spacer (58) and the body (55) of the padlock (50).
  • a fourth embodiment of a padlock (60) is shown in Figures 10 and 11. This embodiment differs from the third embodiment in that the shackle (61) is arch-shaped and is narrower in plan view than the body (62) of the padlock (60).
  • a fifth embodiment of a padlock (70) is shown in Figure 12. This embodiment differs from the third and fourth embodiments in that a recess (71) is formed between the shackle (72) and body (73) of the padlock (70) to expose a pin (74) of the shackle (72) by a stepped shoulder (75) in the body (73). Again, a spacer (76) can be slidably received on the shackle pin (74) to allow a staple (not shown) to be snugly secured on the pin (74).
  • padlocks shown in the preceding Figures are less 5 easily destroyed than conventional padlocks as less of the upper surface of the body of the padlocks is available to receive blows by a hammer and punch, while the limited exposure of the shackle hinders its destruction.
  • slots can be machined into the upper surface of the body of the padlock such that the aprons of the shield fit therein to leave the l o plates of the shield flush with the sides of the body. This will render the padlock more difficult to tamper with.
  • the invention further provides a padlock with an improved body. As shown in
  • a padlock (80) has a shackle (81) and a body (82).
  • the shackle (81) is substantially as described with reference to Figures 7 to 9 and has a first pin (83) and a second parallel pin (84) extending therefrom.
  • the second pin (84) is secured in the body (82) to be rotatable when the shackle is in an
  • Annular spacers (85) are slidably received on the second pin (83) the end of which is selectively securable in the body (82).
  • a bolt (86) is slidably mounted in the body (82) to engage a stepped recess (87,88) in the respective ends of the pins (83,84).
  • the shear area of the bolt (86) is increased over conventional padlocks in that a lip is not machined into the
  • the -bolt (86) is held in a locked condition by a locking pin (89) which operatively locates in a slot (90) in the bolt (86).
  • the locking pin (89) extends from a padlock cylinder (91) which is rotatable by a key (not shown) in conventional manner.
  • the slot (90) is a snug fit over the locking pin (89) thus preventing the bolts (86) sliding out of engagement with
  • the body is secured within a cover (100) in the form of a blind sleeve which is 5 made of a hardened metal.
  • the cover (100) acts to protect the internal components of the body (2) and reduces the need for a thick outer surface on the body (82) to the extent that some of the internal components can abut the cover (100).
  • the bolt (86) is slidable between an upper surface (101) of the cover (100) and the body (2).
  • the ends of the pins (83,84) of l o the shackle (81) project through respective apertures (102,103) in the cover (100) and a base plate (104) is a press-fit in the open lower end (105) of the cover (100).
  • An aperture (106) in the base plate (104) allows a key (not shown) to be inserted in the cylinder (91).
  • the outer surface of the body (82) does not extend fully around the pins (83,83) 15 and these abut the cover (100) in the locked condition. This allows a cylindrical retaining pin (107) to be inserted between the cover (100) and the pin (84) and in turn allows for the pin (84) to seat deeper in the body (82) without increasing the height of the base. Also, the pin (84) can be seated shallower than is normal in the body (82) and this serves to reduce the height of the body (82).
  • the cover (100) also permits harder material to be used than is economically practical for conventional padlocks as little or no machining of the material is necessary to form the cover. Also, the cover (100) allows the body (82) to be made of a relatively low strength material, such as plastics, as the strength and rigidity of the padlock (80) is provided through the cover rather than the body

  • the cover need not be abutted by internal components of the padlock but could be a slide- or press-fit over a conventional padlock body.
  • the cover could take the form of an open ended sleeve or a 30 sleeve closed at one end with an aperture in the end to allow a key to be inserted into the body.
