Definitions
- This invention relates to a lock device and particularly to a lock assembly to be used in conjunction with two or more padlock assemblies.
- Padlock assemblies are in common use today and comprise a fastening member in the form of a shackle which is moveable relative to a main body between closed and open positions.
- a lock is mounted in the main body and can lock the shackle in the closed position.
- Such assemblies are widely used in a variety of applications to restrict the unauthorised relative movement of two or more members such as a hasp and staple fitting, or hasp and padbar fitting.
- Such secure fittings for use with padlock assemblies provide an aperture through which the padlock assembly's shackle can be passed. When the padlock shackle is passed through such an aperture, closed and locked, the unauthorised removal of the padlock assembly is relatively assured.
- a lock device comprising a body member and a fastening member
- the fastening member being received in the body member and being moveable axially relative to the body member between a first open position and a second closed position, the fastening member having a locking formation adapted to engage one or more locking arms when received in the body member so that when the fastening member is in the second closed position and the or each locking arm is engaged with the fastening member, the fastening member cannot be moved into said first open position;
- disengaging one of the locking arms permits the fastening member to be moved transaxially in order to move to the first open position.
- the locking arms can be padlock shackles or bolts extending through apertures through the device to which padlocks are attached thereby locking them to the device.
- the transaxial movement may be rotation or simple movement in a straight line across the axis of movement of the fastening member between the open and closed portions.
- the lock device is a double padlock device or a triple padlock device.
- the body member contains two or three separate apertures, but a single slot for receiving two or more padlock shackles or bolts can be used. Alternatively up to three apertures may be provided
- the body member is a hollow casing.
- the body member is manufactured from steel.
- the apertures can typically be elongate so as to allow transaxial movement of the fastening member.
- the fastening member is a shackle.
- the shackle is U-shaped.
- the fastening member and the locking formation are permitted to rotate with respect to one another to aid release of the fastening member.
- the rotation means comprises a circlip or a grub screw.
- the locking formation has an elongate portion, and most preferably has a shoulder portion also.
- the shoulder portion typically extends laterally from the elongate portion, typically at the end.
- the shoulder portion is typically engaged by one of the shackles.
- two apertures are provided side- by-side in the body member so that shackles engaged therein pass on either side of the elongate portion and at least one passes over the shoulder portion, to retain the fastening member in the body member.
- the other of the shackles passing on the other side of the elongate portion prevents rotational (or other transaxial) movement of the fastening member past the first shackle. Removal of the other (second) shackle permits rotation (or other transaxial movement) of the shoulder past the first. Removal of the first shackle permits simple axial sliding movement of the fastening member from the body to open the device.
- locks may be contained within the body member instead of padlocks or bolts passing through apertures in the body.
- the lock device may contain 2 or 3 locks or more.
- the locks are barrel locks.
- the locking arms typically comprise cams, normally positioned on the top of the locks.
- the locks are disposed in separate sockets in the body. Normally the sockets are in the bottom of the body member.
- the locking arms can move from a first configuration to a second configuration.
- the shoulder portion is typically engaged by one of the cams.
- the cams are positioned on either side of the elongate portion and at least one passes over the shoulder portion, to retain the fastening member in the body member.
- the other of the cams passing on the other side of the elongate portion prevents rotational (or other transaxial) movement of the fastening member past the first shackle.
- Rotation or sliding of the other (second) cam into the second configuration disengages the second cam from the elongate portion and so permits rotation (or other transaxial movement) of the shoulder past the first cam to open the device.
- Rotation or sliding of the first cam into the second configuration disengages the shoulder portion and so permits simple axial sliding movement of the fastening member from the body to open the device.
- At least one locking arm may be a padlock shackle or bolt through the device to which a padlock is attached thereby locking it to the device and at least one locking arm comprises a cam.
- the padlock shackle or bolt has the features described for the first embodiment.
- Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
- Fig. 1 shows a front elevation of a lock device according to the first embodiment of the invention in a closed position with no padlock assemblies fitted;
- Fig. 2 shows a perspective view of the lock device of Fig. 1;
- Fig. 3 shows a perspective view of the lock device of Fig. 1, 2 in an open position
- Fig. 4 shows a front sectional view through the Fig. 1 device in a closed position with two padlock assemblies fitted;
- Fig. 5 shows a front sectional view through the Fig.l device in an open position with the left hand padlock assembly removed;
- Fig. 6 shows a front sectional view through the Fig.l device in an open position with the right hand padlock assembly removed;
- Fig. 7 shows a front sectional view through a lock device according to a second embodiment in an open position with the uppermost padlock assembly removed and Fig. 8 shows a front sectional view through the Fig.7 device in a closed position with padlock assemblies fitted.
- Fig. 9 shows a front sectional view of a third embodiment of a locking device in a closed position with two padlock assemblies fitted;
- Fig. 10 shows a front sectional view of the third embodiment of the device in an open position with the left hand padlock assembly removed;
- Fig. 11 shows a front sectional view of a fourth embodiment of a device in a closed position
- Fig. 12 shows a front sectional view of the fourth embodiment in an open position.
- a multiple padlock device comprises a main body 1, a fastening member in the form of main shackle 2 received in the body 1 via two holes 9 on the upper surface of the main body 1, and a locking formation 7.
- the main body 1 is normally a hollow rectangular casing containing two apertures 3, 4 on each main face 8.
- the apertures 3, 4 are each designed to allow the shackle of a respective padlock 5, 6 to pass through.
- the main body 1 may be made from steel or any other suitably robust material, particularly metals. It can be manufactured by cast moulding or from sheet metal, or by any other suitable method.
- the main shackle 2 is normally U-shaped and can be made from steel or any other robust material, particularly metals.
- On the inner end of the main shackle 2 is a locking formation 7.
- the locking formation 7 and main shackle 2 are normally manufactured together by cast moulding or any other suitable means, but may be made separately and joined together e.g. by welding.
- the main shackle 2 can move in the body 1 between a first open position as shown in figure 3 or in a second closed position as shown in figure 1.
- the locking formation 7 has an elongate portion 10 and a shoulder 11 designed to loop around a shackle 5 of a first padlock as shown in Fig. 4.
- Figure 4 shows the main shackle 2 in its closed position with first and second padlock shackles 5, 6 passing through each of the shackle apertures 3, 4. In this configuration the main shackle 2 cannot move to the open position.
- the shoulder 11 may abut against the second shackle 6 (not shown) .
- the locking mechanism would function in the same way.
- two apertures 9 are present on the topside of the main body 1. These apertures are typically large enough to allow the shackle to tilt as shown in Fig.6 when the second subsidiary shackle 6 is removed.
- FIG. 7 & 8 A second embodiment of the invention is shown in Figs. 7 & 8. This embodiment differs from the first embodiment in that an extra aperture 12 is provided into which a third padlock shackle 13 may be inserted as shown in Fig.8.
- the main shackle 2 cannot slide obliquely to enable the shoulder 11 to bypass the shackle 5 because the locking formation 7 abuts against the second shackle 6 if the locking formation is moved to the right.
- the main shackle 2a itself abuts against the third shackle 13 if it is moved to the left.
- the removal of the third shackle 13 allows the release of the main shackle 2a by permitting the main shackle 2a to move transaxially to the left in the direction of arrow C as shown in figure 7. This permits the shorter shoulder 11a to move between the shackles 5 and 6 as the main shackle 2a is moved axially in the direction of arrow A.
- FIGs. 9 & 10 A third embodiment of the invention is shown in Figs. 9 & 10.
- the third embodiment functions in the same manner as the first embodiment except that the locking formation 7 and main shackle 2c are attached together by a circlip (not shown) or grub screw 14 as shown in Figs. 9-12. This allows rotation between the shackle 2c and the locking formation 7c which eases the release of the shackle from the hasp or other fitting it secures.
- a fourth embodiment is shown in Figs. 11 & 12.
- the fourth embodiment is similar to the third embodiment and so like parts will not be described further.
- the aperture 3 present in other embodiments is not needed in the fourth embodiment.
- a barrel lock 17 is located in a socket 16 in the main body 1 through an aperture 18 in its bottom face 19.
- the barrel lock 17 is mounted in the main body 1 so that the bottom of the barrel lock 17 is exposed to the outside of the device.
- a keyhole 20 is provided at the exposed portion of the barrel lock 17.
- the barrel lock 17 has a lockable arm in the form of a cam 15 mounted on its upper end, movable between a locked position (shown in Fig. 11) and an unlocked position (shown in Fig. 12) .
- the locking formation 7d comprises an elongate portion lOd and a shoulder portion lid designed to loop around the cam 15 in its locked position. When the cam 15 is in this locked position it abuts with the shoulder portion lid to resist axial movement of the shackle as shown in Fig. 11.
- the elongate portion lOd of the locking formation 7d abuts against the padlock bar 6 in the aperture 4 to resist transaxial movement of the locking formation 7b in a similar manner to the first embodiment. Therefore the device is locked.
- the padlock bar 6 may be removed instead of disengaging the cam 15 .
- Transaxial movement of the locking formation 7d is the direction of arrow D is then permitted allowing the shackle 2d to be released in the same manner as that of the first embodiment.
- Additional barrel locks can be used instead of the padbar 6 and apertures 4.
- each barrel lock included an aperture in any suitable face, normally the bottom face, is provided for access to the keyhole.
- the apertures 6 and/or 12 are thus not required when a barrel lock is used instead of separate padlocks.
- Certain embodiments of the invention allow two or more padlock assemblies to be used independently to lock a secure fitting designed for use with only one padlock assembly, whereby the unlocking of any padlock assembly enables the operation or free movement of the secure fitting.
- Certain embodiments of the present invention may be used for secure fittings which are designed for traditional padlocks and is therefore immediately applicable to a variety of secure fittings. This eliminates the need to adapt secure fittings which would be inconvenient and incur additional expenditure.
