Definitions

  • This invention relates to padlocks.
  • Conventional rectangular padlocks are constructed from a body made from a solid block.
  • a shackle bar is pushed into the block across a recess on one side of the body allowing the padlock to be affixed to either a padbar or chain.
  • the shackle bar is locked into position by a key that rotates an offset drum, which in turn pushes a ball bearing into a recess on the shackle bar.
  • a proportion of the shackle bar is left outside the padlock body to enable attachment to a padbar or chain.
  • a padlock comprising first and second swivellable body sections and an interconnecting shackle bar.
  • the padlock can be closed by moving the first and second body sections together to interlock them and also to enclose both ends of the shackle bar.
  • the padlock can be opened by first moving the body sections apart into an intermediate position to release one end of the shackle bar and the interlock between the body sections. From the intermediate position, the padlock is movable into an opened position by swivelling the body sections to expose one end of the shackle bar.
  • the swivel action of the lock allows for a compact construction, since to remove the padlock the two body sections only need to be separated by an amount sufficient to clear one end of the shackle bar from its seat, since then relative rotation of the two body sections, preferably by at least 30 degrees, more preferably between 60 to 90 degrees, then allows the free end of the shackle bar to be swivelled clear of the body section associated with its seat thus providing clear access for removing or installing a chain, padbar or whatever from the padlock.
  • the first and second body sections preferably have corresponding interengageable portions and respective, spaced apart lateral extensions, the shackle bar having a first end arranged in a seat in one of the lateral extensions and a second end positionable into a mutually facing seat in the other of the lateral extensions, the second end of the shackle bar being positioned in its mutually facing seat when the padlock is in the closed position in which the shackle bar and interlocked body sections form a closed loop.
  • the interengageable portions are separated and the second end of the bar is lifted from its seat, so as then to allow relative rotation of the body sections into the opened position -through an angle sufficient to move the second end of the bar clear of the lateral extension associated with its seat.
  • the second body section may have a cavity therein and the first body section has an axle extending into the cavity, the axle being slidably and rotatably engaged in the cavity, wherein the axle includes a locking element that is movable into and out of locking engagement with the second body section when the padlock is in the closed position so as respectively to prevent and allow the first and second body sections from being moved apart, thereby respectively locking and unlocking the padlock.
  • the locking element is mounted beyond an end of the axle and is movable into locking engagement with a corresponding recess in the first body section adjacent the cavity.
  • the locking element is mounted part way along the axle and is movable into locking engagement with a corresponding recess formed in the cavity.
  • a seal to be fitted between the cavity and axle to form a barrier against the ingress of water further into the cavity.
  • the seal may be a lip seal fitted to the cavity or an O-ring fitted to a groove in the axle, for example.
  • the axle and the first body section may form part of a single piece of material or may be separate.
  • the interengageable portions are preferably formed to resist forces acting to cause relative rotation of the body sections about the axle when in the closed position, thereby to prevent stressing of the shackle bar by such forces.
  • the first and second body sections can be designed to interlock to form a barrier against force acting to cause their relative rotation.
  • first and second body sections are shaped to abut in the closed position at first and second abutting surface portions, wherein the second body section has a protective skirt extending from the second abutting surface portion to enclose a part of the first body section so as to resist forces acting to cause swivelling of the body sections when in the closed position, thereby to prevent stressing of the shackle bar by such forces.
  • the padlock may further comprise a retaining mechanism arranged to limit separation of the first and second body sections, thereby to prevent the first and second body sections from being fully separated when the padlock is unlocked, wherein the retaining mechanism includes an actuation element that is externally actuatable to release the retaining mechanism thereby to allow the first and second body sections to be fully separated when the padlock is unlocked.
  • the shackle bar is preferably straight. Moreover, the shackle bar is of circular section in the embodiments described hereinbelow.
  • the first and second body sections have a male/female interlock to provide a form-locked engagement resistive to torque applied transverse to the direction of engagement.
  • the two body sections can be split apart, for example by a linear movement of, for example, 6 mm in one embodiment, allowing the male/female interlock to separate and their registry to disengage. This in turn allows relative rotation of the body sections, which then allows removal of a chain or hasp.
  • the lock mechanism is completely enclosed in the body sections and is sealed with a lip seal, O-ring or other seal, to act as a barrier to water ingress into the lock mechanism between the two lock halves.
  • the lock mechanism is housed in one of the body sections, remote from the shackle bar. Securing a padbar or chain link with a padlock having this feature does not compromise the lock mechanism, since twisting or other forces applied between the padlock and the padbar or chain to which it is locked do not stress the lock mechanism, since they are taken up by interengaging surfaces of the body sections.
  • a retaining mechanism is arranged to limit separation of the first and second body sections, thereby to prevent the first and second body sections from being fully separated in normal use when the padlock is unlocked.
  • the retaining mechanism includes an actuation element, such as a recessed screw, that is externally actuatable to release the retaining mechanism thereby to allow the first and second body sections to be fully separated for servicing when the padlock is unlocked.
  • the shackle bar is rotatably mounted to provide protection against a saw attack on the locked padlock. The shackle bar will then tend to rotate when hacksawed, making cutting very difficult.
  • a rotatable shackle bar can also be advantageously provided in other forms of padlock apart from those according to the first aspect of the invention.
  • a second aspect of the invention relates to a padlock comprising a padlock body housing a locking mechanism and a shackle bar rotatably mounted in one region of the padlock body and extending towards a seat in another region of the padlock body, the bar being slidable into the seat prior to locking of the padlock by actuation of the locking mechanism.
  • a padlock is provided that is resistant to cryogen attack, since the bar can be provided so that it is straight and relatively loosely fitted and thus not stressed by its own contraction caused by cooling, or by differential contraction relative to other parts of the padlock.
  • Figure 1 shows in perspective the padlock in a closed position in which it can be locked and unlocked by means of a locking mechanism disposed within the main body of the padlock as will be described further below with reference to Figures 3 and 4 in particular.
  • the padlock has two main parts, namely cooperating lower and upper body sections 1 and 2, as well as a shackle bar 8 that extends between lateral extensions 34 and 33 of the lower and upper body sections 1 and 2 respectively.
  • the shackle bar is straight and of circular section in the present embodiment, although it will be understood that a large variety of bar shapes and configurations may be used.
  • the first, lower body section 1 and the second, upper body section 2 may be made of conventional materials such as lock-grade stainless steel, or brass.
  • Figure 2 illustrates the padlock in an opened position in which the upper body section 2 has been rotated through approximately 90° from the locked position relative to the lower body section 1.
  • the body sections are first moved apart and thus disengaged.
  • the upper body section can be lifted in the direction of the arrow shown in Figure 2 from the lower body section.
  • the body sections 1 and 2 are separated by a sufficient degree to disengage corresponding inter-engageable portions 29 and 30 of the lower and upper body sections 1 and 2 respectively.
  • the upper body section 2 can then be swivelled through 90° to the opened position illustrated in Figure 2 in which there is maximum clear access to the shackle bar 8.
  • the padlock In the opened position, the padlock can be easily attachable and detachable from a padbar or chain.
  • the swivel action thus provides good access for installing and removing the padlock, while at the same time allowing for a compact construction compared with a construction in which a straight shackle bar is moved along its own axis during installation and removal of the padlock. Constructions of this type are in widespread use for motorcycle locks which are fixed through holes in a drilled disc of a disc brake.
  • Figure 3 shows cut-away views of the padlock when in the closed position illustrated in Figure 1.
  • the first and second body sections 1 and 2 are shown in section with diagonal dashed lines.
  • the corresponding inter-engageable portions 29 and 30 are interlocked in the illustrated closed position to provide resistance against relative rotation of the body sections 1 and 2.
  • the shackle bar 8 has a first, lower end 32 positioned in a corresponding seat 27 in the lateral extension 34 of the lower body section 1.
  • the lower end 32 of the bar 8 is retained in its seat 27 by means of a retaining screw 7 which engages in a groove formed by a waisted portion 28 in the lower end 32 of the bar 8.
  • a second, upper end 31 of the bar 8 is positioned in a corresponding seat 24 in the lateral extension 33 of the upper body section 2.
  • the shackle bar 8 is rotatably mounted in the seat 27 so as to allow swivelling about its own axis, as illustrated by the chain-dotted line in Figure 4.
  • the bar 8 When in the closed position, the upper and lower body sections abut with a skirt 35 in the upper body section 2 enclosing and thereby protecting the male and female inter-engaging portions 29 and 30 from attack. Moreover, the bar 8 has both its end sections 31 and 32 fully enclosed in their respective seats thus defining a closed loop enclosure 19 through which a padbar or section of a chain link can be positioned.
  • FIG 4 is an exploded view of the components of the padlock and the locking mechanism is now described with reference to this figure, noting that many of the components of the locking mechanism are also illustrated in Figure 3.
  • a conventional lock barrel 3 is housed in the lower body section 1 with a keyhole for receiving a key 15, accessible from the underside of the lower body section 1.
  • the lock barrel is of the Eurocylinder type.
  • An anti-drill shield 13 is fitted between the lower body section 1 and the lock barrel 3.
  • the bung 14 may be retained to the lower body section by a strap or the like (not illustrated).
  • the lock barrel 3 housed in the lower body section 1 is retained by the underside of an axle mounting plate 26 using retaining screws 10, one of which is illustrated.
  • the axle mounting plate 26 forms a lower flange of an axle 4 of generally cylindrical shape which is arranged upstanding from the lower body section 1 and forms part thereof.
  • the axle 4 extends into a cavity in the upper body section 2, the cavity being formed in its lower part as a bore 25 in which the axle 4 is slidably and rotatably engaged.
  • the axle 4 and bore 25 thus serve as means by which the upper body section 2 can be revolved or turned round the lower body section 1.
  • axle 4 need not necessarily be a single upstanding cylindrical stub and the bore 25 may not be a plain cylindrical bore, as illustrated.
  • the axle 4 may be formed of multiple splines arranged in a circle, or the axle 4 and cavity bore 25 may be replaced with any conventional bearing or bushing arrangement.
  • a seal in the form of an O-ring 9 is arranged in a groove extending around the periphery of the axle 4.
  • the outer surface of the O-ring 9 bears on the inner surface of the bore 25, both in the closed position shown in Figure 1 and the opened position shown in Figure 2, and in all intermediate positions, thereby forming a barrier against the ingress of water into upper portions of the cavity where movable parts of the locking mechanism are disposed.
  • the axle 4 has a vertical bore passing therethrough offset from the principal axis of the axle in which bore is received a cam shaft 5 which is held captive in the axle 4 by a cam retaining plate 11 which is fitted into a slot in the axle 4 and engages into a waisted portion 22 of the cam shaft 5.
  • a cam 21 which is rotated by rotation of the cam shaft 5, which is in turn caused by rotation of a key 15 in the lock barrel 3, to move the cam 21 into and out of a locking recess 20 formed in the upper body section 2 adjacent to the upper end of the cavity.
  • the cam 21 is of circular section and has a diameter slightly smaller than that of the axle 4.
  • the cam 21 In its unlocked position, illustrated by the solid line drawing of the cam 21 in Figure 4, the cam 21 does not extend beyond the outer periphery of the axle 4, thus allowing the upper and lower body sections to be moved apart from the closed position up to a maximum amount defined by a retaining mechanism in the form of a retaining screw 6 in the upper body section 2 and an associated abutment in the lower body section 1 that are arranged to prevent total separation of the body sections.
  • Retention may for example be achieved by a vertical slot extending part way along the axle such that the lower end of the slot (not shown) serves as an abutment for the retaining screw 6.
  • a compression spring 12 positioned in a recess on the upper side of the cam 21 serves to provide an urging force to assist separation of the body halves prior to subsequent rotation into the position shown in Figure 2.
  • Figure 5 shows in plan view from above the cam 21 with the recess for the spring 12 arranged symmetrically about the axis of rotation of the underlying cam shaft 5.
  • Figures 6, 7 and 8 are further schematic representations of the padlock in three different positions.
  • Figure 6 shows the padlock in the closed position.
  • Figure 7 shows the padlock in an intermediate position in which the two body sections 1 and 2 are separated.
  • Figure 8 shows the padlock in the opened position shown in Figure 2 in which the upper and lower body sections have been rotated by approximately 90° from the closed position.
  • the key 15 is turned to disengage the locking cam 21 from its recess 20 and bring it into alignment with the axle 4.
  • the two body sections 1 and 2 become separable and are urged apart into the position shown in Figure 7 by the action of the compression spring 12.
  • the body sections are separated by an amount sufficient to disengage the mutually engaging portions 29 and 30 and to lift the upper end 31 of bar 8 clear of its seat 24 by a clearance distance d.
  • the lower body section 1 can then be swivelled relative to the upper body section 2, wherein maximum access is provided by rotation through 90°. Clockwise or anti-clockwise rotation is possible with this embodiment.
  • 90° relative rotation of the body halves from the closed position will provide maximum access, it will be understood that sufficient access will also be provided by lesser amounts of rotation and that other embodiments of the invention may not allow for rotation beyond an angle of, for example, 30° ,45° or 60°.
  • the separation movement from the closed position to the intermediate position shown in Figure 7 is approximately 6mm and the clearance of the upper end 31 of the bar 8 at this intermediate position is approximately 1 or 2mm.
  • Figure 9 shows a cut-away view of the padlock of the second embodiment, this view corresponding to that of Figure 3 of the first embodiment.
  • the components and operation of the padlock of the second embodiment are similar to those of the first embodiment and like reference numerals have been used to label corresponding components to aid understanding.
  • the main outer construction of the padlock is the same as in the first embodiment, as is the design and mounting of the shackle bar 8 in the lateral extensions 33 and 34 of the body sections.
  • the second embodiment differs somewhat from the first embodiment in the construction of the locking mechanism, more especially in the manner in which the lock barrel 3 is housed and in features of the axle 4, cam shaft 5 and locking cam 21.
  • the lock barrel 3 is fitted during assembly when the lock bodies 1 and 2 are in half.
  • the axle 4 is a separate component.
  • a possible limitation of the first embodiment could be a potential weakness of the connection between the axle 4 and lower body 1.
  • the lower body 1 and axle 4 of the first embodiment are of a unitary construction by forming both elements integrally from a single piece of material, thus improving strength against attack.
  • the axle/lower body unit can, for example, be machined from a single block of metal, such as stainless steel.
  • the lock barrel 3 is fitted externally from underneath and retained by a lock barrel retaining plate 13, which also forms an anti-drill shield, and is held in position using screws 10.
  • the cam 21 is retained in a slot positioned part way along the axle 4.
  • This modification is for increased strength against attack in respect of forces acting to pull the body sections apart, which act on the cam 5. Moreover, this modification provides for improved ease of manufacture.
  • an O-ring 9 is provided as a seal on the axle 4.
  • the O-ring is replaced with a lip seal 9 mounted adjacent the entrance to the bore 25.
  • the lip seal 9 is considered more efficient as a barrier to water and moisture.
  • an O-ring 110 has been added to the cam shaft 5 to form a seal between the outer surface of the cam shaft 5 and the inner surface of the bore in the axle 4 through which it passes. The O-ring 110 serves to stop water ingress to the main locking components, even if the keyhole is not sealed.
  • a plastic keyhole cover 14 is snap fitted into a peripheral groove extending around a lower rim of the lower body section 1 and has an aperture through which key access to the keyhole is possible, the aperture being sealable by a bung held on a strap (not shown).
  • axle retention is also performed in a different way.
  • a retaining screw 6 is provided, as in the first embodiment, but retention is effected by a head of the screw which is free to travel within bounds defined by a recess 17, the sides of which form abutments for the head of the retaining screw, thus limiting separation of the body sections to an amount sufficient to allow movement between the above-mentioned closed, intermediate and opened positions.
  • the head of the retaining screw 6 is accessible through a hole 18 which is sealed with a waterproof bung 16 after assembly.
  • the spring 12 of the first embodiment is omitted, as it has been established that separation of the body sections can be performed adequately without any positive urging of cam shaft 5 away from the upper body section 2.
  • the padlock of the third embodiment has an intermediate lateral extension 40 which forms part of one of the body sections, the lower body section 1 in the illustration.
  • the intermediate lateral extension 40 has a hole through which the shackle bar 8 passes, thereby sub-dividing the bar 8 into first and second exposed sections for receiving respective chain links and defining closed loop enclosures 19a and 19b.
  • the lower and upper exposed sections have lengths t 1 and t 2 respectively which are preferably of similar dimension, namely a dimension slightly larger than a corresponding width t of a chain link of a chain as illustrated in Figure 13 by way of example.
  • the shackle bar 8 can be fully removed to allow one link of the chain to be fitted between the lower lateral extension 34 and the intermediate lateral extension 40.
  • a retaining screw such as the retaining screw 7 of the first and second embodiments
  • this can be disengaged to allow bar removal and placement of a chain link into the lower enclosure 19a of the padlock.
  • a chain can thus be semi-permanently attached by one end link to the lower body section 1 of the padlock.
  • the other end link of the chain can then be fitted to and removed from the padlock as desired by separation and swivel action of the upper body section 2 as illustrated in Figure 12, thereby opening the enclosure 19b to allow free access to the upper end of the shackle bar 8.
  • the internal construction of the padlock of the third embodiment may follow that of either the first or second embodiments as described above.
  • a fourth embodiment of the invention is now described with reference to Figures 14 and 15 which show front and rear side views of a padlock.
  • the padlock of the fourth embodiment has a modified exterior construction in that flange extensions 50 and 51 are provided in the upper and lower body sections 2 and 1 respectively.
  • the flanges 50 and 51 extend to restrict access to the padlock enclosure from one side of the padlock, thereby to further improve security against attack.
  • This embodiment is specially adapted for use in locking shutters of the kind common in shop fronts.
  • the padlock can be installed with the flanges 50 and 51 facing upwards, the other side of the padlock enclosure which is not protected by the flanges being partially obscured by the padlock's close proximity to the ground or to a window ledge or the like.
