Title: Lock for securing a toolbox to a support structure

Description:
DESCRIPTION OF INVENTION 
     Embodiments of the present invention relate to a lock for a toolbox or other wheeled objects, a toolbox lock, a toolbox and toolbox lock, and associated methods. 
     Toolboxes are commonly found in garages and other similar environments in which tools are required. In many instances, these toolboxes are generally in the form of wheeled cabinets which can be wheeled across a floor surface (to a convenient location). 
     The toolboxes themselves can be expensive. Furthermore, the tools which the toolboxes store can also be expensive. The toolboxes, therefore, represent a tempting target for thieves. Toolboxes which are mounted on wheels are particularly attractive targets for thieves because of the easy of mobility of the toolboxes. 
     There is, therefore, a need to provide a mechanism to secure a toolbox. 
     WO2008/023144 discloses a security device which comprises a received mounted to the floor and a pin mounted to the base of a cabinet. With the pin and receiver aligned, the pin can be lowered into the receiver and secured in place with a padlock. The document only discloses cabinets which are supported by legs and which are not, therefore, intended to be moved on a frequent basis. As will be appreciated, this device requires precise alignment of the pin and receiver, with the cabinet supported above the floor surface. Such a device would not be operable to secure a wheeled cabinet, is awkward to use, and requires the cabinet to undergo significant modification to secure the pin thereto. 
     Embodiments of the invention seek to ameliorate one or more problems associated with the prior art. 
     An aspect of the present invention provides a lock for securing a toolbox to a support structure, the lock comprising: a first lock portion configured to receive a first part of the toolbox or a first attachment of the toolbox; and a second lock portion configured to engage a second part of the toolbox or a second attachment of the toolbox, the second lock portion being lockable to inhibit or substantially prevent disengagement of the second part or second attachment, wherein: the second lock portion is remote from the first lock portion, the first and second lock portions are securable with respect to a support structure, and the first lock portion is configured to guide movement of the second part of the toolbox or the second attachment of the toolbox into engagement with the second lock portion. 
     The first lock portion may comprise a body which defines a channel which is configured to receive the first part of the toolbox or first attachment. 
     The second lock portion may include a hook which is configured to engage the second part of the toolbox or second attachment. 
     The hook may be moveable between a stowed and an operative condition. 
     The second lock portion may include a bolt and the hook defines a bolt receiving aperture which is configured to receive at least part of the bolt. 
     The hook may be rotatable with respect to a main body of the second lock portion. 
     The hook may be further configured for linear movement with respect to the main body. 
     The second lock portion may include a resilient biasing arrangement which is configured to bias the hook into an engaging position in which the second part of the toolbox or second attachment is moveable into and/or out of a hook recess. 
     Movement of the hook against the resilient biasing arrangement may move the hook into a locking position in which the second part of the toolbox or second attachment is inhibited or substantially prevented from leaving the hook recess. 
     The first and second lock portions may be securable to the support structure. 
     Another aspect provides a lock for securing a toolbox to a support structure, the lock comprising: a lock portion securable with respect to a support structure; and a lock engagement member, wherein the lock engagement member is configured to be mounted to a ground engaging mechanism of the toolbox and the lock portion is configured to engage the lock engagement member, the lock portion being selectively lockable to inhibit or substantially prevent disengagement of the lock engagement member from the lock portion. 
     The lock may further include another lock portion securable with respect to the support structure and configured to receive another part of the toolbox or another attachment of the toolbox. 
     The ground engaging mechanism may be a caster. 
     The lock engagement member may be mounted to an axle bolt of the ground engaging mechanism. 
     Another aspect provides a lock for securing a toolbox to a support structure, the lock comprising: a lock portion having a member which is configured to engage a part of a toolbox or an attachment of the toolbox and which is selectively lockable to inhibit or substantially prevent disengagement of the part or attachment of the toolbox, wherein the member of the lock portion is moveable between an operative condition in which the member extends from the support structure a first distance and a stowed condition in which the member extends from the support structure a second distance which is less than the first distance. 
     The member may be a hook which is rotatable with respect to a main body of the lock portion. 
     The hook may be configured to resist movement from the stowed condition to the operative condition. 
     The member may define an aperture configured to receive a pin, wherein the pin extends through a first part of the aperture when the member is in the operative condition and through a second part of the aperture when the member is in the stowed condition. 
     The member may extend generally vertically when in the stowed condition and generally horizontally when in the operative condition. 
     The lock may further include a padlock or integral lock. 
     Another aspect provides a toolbox and toolbox lock combination, wherein the lock is as above. 
     The toolbox and toolbox lock combination may further include one or more tools.

     With reference to  FIGS. 1 to 19 , embodiments of the present invention include a toolbox lock  1 . The toolbox lock  1  is configured to secure a toolbox  100  to a support structure  200  such as a wall. 
     The toolbox  100  may comprise a toolbox body  101  which is supported with respect to a floor surface by a ground engaging mechanism  104  (which may include one or more wheels or castors  102  and may, therefore, have the form of a wheeled cabinet). The toolbox body  101  defines a tool storage volume for the storage of one or more tools—such as hand tools (e.g. spanners (i.e. wrenches), screwdrivers, sockets, clamps, pliers, and the like). The toolbox body  101  may carry (and include) one or more drawers  103  or other arrangements or partitions which at least partially define portions of the tool storage volume and which allow for organisation of one or more tools stored therein. For example, a toolbox body  101  may carry one or more drawers  103  which are each moveable (with respect to the rest of the toolbox body  101 ) between an open and a closed condition independently of each other (or in groups). When a drawer  103  is in the open condition, access is provided to one or more tools stored in that drawer  103 . When a drawer  103  is in the closed condition, access to one or more tools stored in that drawer  103  is inhibited or substantially prevented. The or each drawer  103  may be slideably mounted (on a linear or curved runner) with respect to another part of the toolbox body  101 . 
     In some embodiments, the toolbox body  101  includes one or more doors which are each configured to move with respect to another part of the toolbox body  101  to provide access to at least part of the tool storage volume when in an open condition and to inhibit or substantially prevent such access when in a closed condition. The or each door may be pivotably mounted (e.g. by a hinge mechanism) to another part of the toolbox body  101 . The or each door may be slideably mounted (on a linear or curved runner) with respect to another part of the toolbox body  101 . 
     The one or more doors and/or drawers  103  which may be provided are examples of closure arrangements moveable between an open and a closed condition. 
     The toolbox body  101  (including any closure arrangements) may have a generally cuboid form. The toolbox body  101  may have a front face  101   a  in relation to which one or more closure arrangements (as described above) are provided. The toolbox body  101  may include a rear face  101   b  which generally opposes the front face  101   a  across a depth of the toolbox body  101 . The toolbox body  101  may include two opposing side faces  101   c  which oppose each other across a width of the toolbox body  101 . The toolbox body  101  may include a top face  101   d  which generally faces upwardly with the toolbox  101  in a typically orientation and bottom face  101   e  which generally faces downwardly with the toolbox  101  in the typical orientation—the top face  101   d  and bottom face  101   e  generally opposing each other across a height of the toolbox body  101 . 
     Each face  101   a,b,c,d,e  of the toolbox body  101  may be a generally planar face. One or more of the faces  101   a,b,c,d,e  may include one or more closure arrangements (as described above). In many embodiments, however, all or the majority of the closure arrangements are provided in the front face  101   a . The top face  101   d  may include one or more other features protruding therefrom or associated therewith. For example, in some embodiments, the top face  101   d  forms a closure arrangement in the form of a lid which is pivotably mounted with respect to another part of the toolbox body  101  to provide access to a part of the tool storage volume generally towards the top of the toolbox body  101  (a part of the volume which may be partially defined by a shelf which is generally parallel to the bottom face but spaced apart therefrom). 
     The toolbox body  101  may be formed from sheet metal—such as steel, stainless steel, or aluminium, for example. 
     In some embodiments, the side faces  101   c , and/or the bottom face  101   e , and/or the top face  101   d  are each formed from a respective single sheet of material. 
     The toolbox body  101  may include, for example, an internal frame (not shown) which supports one or more sheets of material forming the faces  101   a,b,c,d,e  thereof. 
     Towards the bottom face  101   e  the ground engaging mechanism  104  is provided. The ground engaging mechanism  104  may include one or more wheels which may be in the form of respective castors  104   a  (each castor  104   a  comprising a wheel which is rotatable amount an axle axis and a direction axis, the axle axis and direction axis being generally perpendicular to each other). The or each castor  104   a  is configured to allow the movement of the toolbox  100  across a ground surface and, in some embodiments, this movement may be permitted in substantially any direction due to the configuration of the or each castor  104   a  (and, in particular, the ability of each wheel of each castor  104   a  to rotate about its direction axis). 
     In some embodiments, each castor  104   a  includes a plurality of wheels which are configured for rotation about a common axle axis for that castor  104   a  (and a common direction axis). 
     The toolbox  100  may include a plurality of parts and each part may include its own toolbox body  101  as described above. The plurality of toolbox bodies  101  may be attached to each other—each with one stacked on another. In a stacked configuration, the bottom most toolbox body  101  or bodies  101  may include a ground engaging mechanism  104 . 
     A first lock engagement member  11  is mounted to the toolbox  100 . In some embodiments, the first lock engagement member  11  may be mounted to the ground engagement mechanism  104  of the toolbox  100  and may, in such embodiments, be mounted to a castor  104   a  thereof. In some embodiments, the first lock engagement member  11  may be mounted to an axle of a castor  104   a  or other fixing element which is used to secure the wheel—the axle axis may be aligned with and parallel to a longitudinal axis of the first lock engagement member  11 . 
     In some embodiments, the first lock engagement member  11  may be mounted to the toolbox body  101 . In such embodiments, the first lock engagement member  11  may be mounted such that its longitudinal axis is generally parallel or perpendicular to a plane of the rear face  101   b  of the toolbox body  101 . 
     In some embodiments, a second lock engagement member  12  may be mounted to the toolbox  100 . The second lock engagement member  12  may be remote from the first lock engagement member  11 . In some embodiments, the first and second lock engagement members  11 , 12  are separated by a distance which is approximately equal to the width of the toolbox  100  or the depth of the toolbox  100 . 
     In some embodiments, the second lock engagement member  12  may be mounted to the ground engagement mechanism  104  of the toolbox  100  and may, in such embodiments, be mounted to a castor  104   a  thereof. In some embodiments, second lock engagement member  12  may be mounted to an axle of a castor  104   a  or other fixing element which is used to secure the wheel—the axle axis may be aligned with and parallel to a longitudinal axis of the second lock engagement member  12 . The first and second lock engagement members  11 , 12  of some embodiments are mounted to respective different castors  104   a  of the ground engagement mechanism  104 . 
     In some embodiments, the second lock engagement member  12  may be mounted to the toolbox body  101 . In such embodiments, the second lock engagement member  12  may be mounted such that its longitudinal axis is generally parallel to a plane of the rear face  101   b  of the toolbox body  101 . 
     The toolbox lock  1  includes a first lock body  13  and a second lock body  14 . The first lock body  13  and second lock body  14  are configured to engage respective parts of the toolbox  100  or attachments thereof. In some embodiments, each lock body  13 , 14  is configured to engage a respective lock engagement member  11 , 12 . In some embodiments, the first lock body  13  is configured to engage a castor  104   a  or a part thereof, and the second lock body  14  is configured to engage the second lock engagement member  12  (in such embodiments, the first lock engagement member  11  may not be provided). In some embodiments, the first lock body  13  is configured to engage a first castor  104   a  or a part thereof, and the second lock body  14  configured to engage a second castor  104   a  or a part thereof. 
     The first lock body  13  in some embodiments is in the form of a receiver which is configured to receive a part of the toolbox  100  or an attachment thereof. As such, in some embodiments, all or part of a castor  104   a  may be receivable within the first lock body  13 . In some embodiments, all or a part of the first lock engagement member  11  is receivable within the first lock body  13 . 
     The first lock body  13  is configured such that a part of the toolbox  100  or an attachment thereof can be moved into engagement with the first lock body  13  from at least one direction but the engagement inhibits or substantially prevents movement of that part of the toolbox  100  or the attachment thereof with respect to the first lock body  13  in at least one other direction. 
     In some embodiments, the first lock body  13  defines a channel  131  to receive a part of the toolbox  100  or an attachment thereof. The first lock body  13  may further define an elongate slot  132  and an access aperture  133  for the channel  131 . The access aperture  133  may be located towards an end open end of the elongate slot  132 . Accordingly, a part of the toolbox  100  or an attachment thereof may be inserted into the channel  131  through the access aperture  133  and then moved along the elongate slot  132  away from the access aperture  133 . The received part or attachment may be configured (i.e. sized and shaped) such that it cannot be removed from the channel  131  via the elongate slot  132  but would instead need to be moved back out through the access aperture  133 . The received part or attachment may be coupled to another part which extends through the elongate slot  132  and which is coupled to the toolbox  100  or the rest of the toolbox  100  as the case may be. 
     In embodiments in which it is at least a part of the first lock engagement member  11  which is received by the first lock body  13 , the first lock engagement member  11  may comprise an elongate member  111  with a proximal end which is coupled to the toolbox  100  (e.g. to a castor  104   a ), and a free end. The free end may carry an abutment member or head  112  which has a larger thickness (e.g. diameter) than the elongate member  111 . Accordingly, the first lock engagement member  11  may have a generally T-shaped cross-sectional shape (through a plane which is parallel to a longitudinal axis of the elongate member  111 ). The elongate member  111  and the abutment member  112  may have respective circular cross-sectional shapes (through a plane generally perpendicular to the longitudinal axis of the elongate member  111 ). 
     The first lock body  13  may define a channel  131  which is generally rectangular in cross-sectional shape. Accordingly the first lock body  13  may include a rear wall which is configured to be secured to the support structure  200  (such as a wall)—for example, the rear wall may define one or more apertures configured to receive respective bolts or screws. Upper and lower sidewalls may extend from respective upper and lower edges of the rear wall and may carry a front wall (which is generally parallel to the rear wall and separated therefrom by a depth of the channel  131 ). The front wall may define the elongate slot  132  and the front wall, rear wall, and side walls may define the access aperture  133 . 
     In some embodiments, the access aperture  133  has a depth which is greater than the depth of the channel  131 . This may be achieved by flared portions of the front wall—which may be flared portions above and below the elongate slot  132 . 
     In some embodiments, therefore, the abutment member  112  may be aligned with the access aperture  133  for reception thereby. Movement of the abutment member  112  through the access aperture  133  allows the elongate member  111  to be partially received by the elongate slot  132 . The elongate member  111  may be moved along the elongate slot  132  away from the access aperture  133  such that the abutment member  112  is received within a part of the first lock body  13  which may be remote from the access aperture  133 . Accordingly, the first lock engagement member  11  and the first lock body  13  may be engaged. Disengagement requires movement of the elongate member  111  (and abutment member  112 ) back along the elongate slot  132  and out of the access aperture  133 —as movement of the first lock engagement member  11  out of engagement in a direction roughly parallel to the longitudinal axis of the elongate member  111  is inhibited or substantially prevented by the abutment member  112  abutting the first lock body  13  adjacent the elongate slot  132 . 
     In some embodiments, access to the channel  131  from an end of the first lock body  13  remote from the access aperture  133  is inhibited by a plate or mesh at that end of the first lock body  13  (which extends across at least part of the channel  131 ). 
     In some embodiments, the first lock engagement member  11  has a double headed configuration (as depicted in  FIG. 20 ). Accordingly, the free end may carry a pair of abutment members or heads  12   a  which define a recess therebetween. The recess defined by the pair of abutment members or heads  12   a  may be configured to receive at least part of the first lock body  13 . In some embodiments, the recess is configured to receive at least part of the front wall of the first lock body  13  and, as such, the depth of the recess (between the pair of abutment members or heads  12   a ) may be greater than a thickness of the front wall of the first lock body  13 . In some embodiments, a first of the pair of abutment members or heads  12   a  may be locatable to one side of the front wall and a second of the pair of abutment members of the heads  12   a  may be locatable to the opposing side of the front wall when the first lock engagement member  11  is at least partially received by the elongate slot  132 . The pair of abutment members or heads  12   a  may assist the user in locating the first lock engagement member  11  in the first lock body  13  and/or may assist in the guiding of the first lock engagement member  11  along the elongate slot and/or may assist in blocking at least part of the first lock body  13  from interference. 
     The second lock body  14  is configured for lockable and selective engagement of a part of the toolbox  100  or an attachment thereof. Accordingly, part of the toolbox  100  or an attachment thereof may be engaged with the second lock body  14  and the second lock body  14  may be configured to be locked to that part of the toolbox  100  or attachment such that movement of the toolbox  100  out of engagement is inhibited or substantially prevented. 
     The second lock body  14  in some embodiments includes a hook  141  which is configured to capture a part of the toolbox  100  or an attachment thereof. As such, in some embodiments, all or part of a castor  104   a  may be captureable by the second lock body  14 . In some embodiments, all or a part of the second lock engagement member  12  is captureable by the second lock body  14 . 
     The second lock body  14  is configured to be actuated between a locked condition in which the second lock body  14  is inhibited or substantially prevented from disengaging a part of the toolbox  100  or an attachment thereof (e.g. the hook  141  is inhibited or substantially prevented from releasing the captured part or attachment) and an unlocked condition in which the second lock body  14  is not substantially prevented from disengaging a part of the toolbox  100  or an attachment thereof (e.g. the hook  141  is not substantially prevented from releasing the captured part or attachment). 
     The second lock body  14  may comprise a main body  142  which is configured to be mounted to the support structure  200  (such as a wall). The main body  142  may comprise a mounting plate which, in some embodiments, is generally rectangular in shape. The main body  142  may define one or more mounting apertures  144 . In some embodiments, there are two or more such mounting apertures  144  defined and in some embodiments, there are three such mounting apertures  144  defined. In some embodiments, the two or more (or three) mounting apertures  144  are generally aligned along a common linear axis of the main body  142  (that axis being parallel to and spaced apart from a bolt axis). 
     At least one of the mounting apertures  144  is protected by a shield member  145 . The shield member  145  may take a number of different forms and is configured to inhibit access to a bolt, screw, or other attachment member which is received by the mounting aperture  144  and which is configured to help to secure the main body  142  to the support structure. 
     In some embodiments, a pair of shield members  145  is provided for each mounting aperture  144 . Each shield member  145  may comprise a protrusion which extends outwardly from the main body  142  adjacent a mounting aperture  144 . In some embodiments, each shield member  145  may be formed from material of the main body  142 —this material may have been at least partially cut or otherwise severed to form at least part of the mounting aperture  144  to which it is adjacent and then bent or re-attached such that it protrudes at an angle with respect to a plane of the main body  142  of the second lock body  14 . 
     The hook  141  may be pivotably mounted to the main body  142  of the second lock body  14 . This pivotable mounting may be between a pair of protective side plates  143  such that the hook  141  is sandwiched between the protective side plates  143  at a proximal end of the hook  141 . The protective side plates  143  may extend away from the main body  142  and this extension may be generally in a direction which is perpendicular to the plane of the main body  142  of the second lock body  14 . The hook  141  may be sized and shaped to fit, at least partially, between the two protective side plates  143  if provided. 
     The pivotable mounting of the hook  141  to the main body  142  may be a pivotal mounting to one or both of the pair of protective side plates  143 . For example, in some embodiments, the two protective side plates  143  may define respective pin receiving apertures which are configured to receive a pin  146  such that the pin  146  is supported by both protective side plates  143  and extends there between. 
     The hook  141  may define a pin receiving aperture  1411  which is configured to receive at least part of the pin  146  which extends between the two protective side plates  143 . 
     The hook  141  may be pivotable between a stowed and an operative condition. In the stowed condition, the hook  141  extends mainly in a direction generally parallel to a plane of the main body  142 . The operative condition, the hook  141  extends mainly in a direction generally perpendicular to the plane of the main body  142  such that it is in position to engage a part of the toolbox  100  or an attachment thereof. In the operative condition the hook  141  extends away from the support structure  200  a first distance and in the stowed condition the hook  141  extends away from the support structure  200  a second distance which is less than the first distance. 
     The hook  141  may be configured such that is retained in the stowed condition and requires user interaction to move the hook  141  into the operative condition. This user interaction may be the actuation of a control mechanism or, for example, the lifting of the hook  141  relative to the main body  142 . 
     In some embodiments, the hook  141  defines the pin receiving aperture  1411  and the pin receiving aperture  1411  is elongate such that a length of the pin receiving aperture  1411  is greater than a width of the pin receiving aperture  1411 . The width of the pin receiving aperture  1411  may be generally equal to (or marginally greater than) a diameter of the pin  146  such that the hook  141  is mountable to the pin  146  via the pin receiving aperture  1411 . The length of the pin receiving aperture  1411  may be generally aligned along a longitudinal axis of the hook  141 . Accordingly, with the hook  141  in the operative condition, the pin  146  is received by a first part of the pin receiving aperture  1411  towards a first end of that aperture  1411 . With the hook  141  in the stowed condition, the pin  146  is received by a second part of the pin receiving aperture  1411  towards a second end of that aperture  1411 . The position of the pin receiving aperture  1411  and the pin  146  may be such that with the hook  141  in the stowed condition, a longitudinal edge of the hook  146  abuts the main body  142 . In addition, a corner between the longitudinal edge and an end edge is below an axis of the pin  146 . This inhibits or substantially prevents the rotation of the hook  141  with respect to the main body  142  into the operative condition. 
     With the hook  141  in the stowed condition, in such embodiments, movement of the hook  141  to the operative condition requires lifting of the hook  141  such that the corner is closer to the axis of the pin  146 . The corner may have a radius or may be otherwise configured such that when it is in the hook  141  is lifted, there is sufficient room for the hook  141  to rotate about the pin  146  and the corner to move with respect to the main body  142  during that rotational movement of the hook  141 . Thus, with the hook  141  so lifted, rotation of the hook  141  about the pin  146  is no longer inhibited and the hook  141  is rotatable to the operative condition. 
     The second lock body  14  may, in some embodiments, include a resilient biasing arrangement  147  which is configured to act on the hook  141 . The resilient biasing arrangement  147  is configured to bias the hook  141  into an engaging position of the operative condition. The application of a sufficient force against the biasing force of resilient biasing arrangement  147  moves the hook  141  downwardly towards a locking position of the operative condition. 
     The hook  141  defines a bolt receiving aperture  1412  which is configured to receive at least part of a bolt  148 . In embodiments the protective side plates  143  each define respective further bolt receiving apertures  1431 . The further bolt receiving apertures  1431  are generally aligned with each other such that the bolt  148  of the second lock body  14  is configured to pass through the further bolt receiving apertures  1431 . Furthermore, with the hook  141  in the locking position of the operative condition, the bolt receiving aperture  1412  is aligned with the further bolt receiving apertures  1431  such that at least part of the bolt  148  is receivable by the bolt receiving aperture  1412  and the further bolt receiving apertures  1431  to lock the hook  141  in position with respect to the main body  142 . 
     The resilient biasing arrangement  147  may comprise a spring screw—a threaded bolt carrying a biasing member which is biased towards a position with respect to a body of the threaded bolt by an internal spring. Other resilient biasing arrangements  147  are envisaged. 
     In some embodiments, the resilient biasing arrangement  147  is configured to act on a lower longitudinal edge of the hook  141 . In some embodiments, the resilient biasing arrangement  147  is configured to act on the end edge of the hook  141 . 
     In some embodiments, the resilient biasing arrangement  147  is mounted with respect to the main body  142  and is configured to act on a portion of the hook  141  or a member mounted thereto. For example, a member may be mounted to the hook  141  and configured to engage the resilient biasing arrangement  147 . The resilient biasing arrangement  147  may be mounted to a plate or other member which is mounted to the main body  142 . The resilient biasing arrangement  147  may comprise a generally rigid member which abuts a member which is mounted to the hook  141  and a spring (or other resilient biasing means) may act on the generally rigid member which, in turn, acts on the member which is mounted to the hook  141 . When the hook  141  moves against the biasing force, the generally rigid member may move with respect to the main body  142  (e.g. through an aperture defined thereby or by a member or plate mounted thereto). The generally rigid member may include a stop to inhibit movement of the generally rigid member beyond a desired position under the biasing force. 
     Accordingly, in some embodiments, the resilient biasing arrangement  147  is mounted next to or otherwise adjacent the hook  141  and, in some embodiments, the resilient biasing arrangement  147  is mounted such that it is in generally the same plane as the hook  141 . 
     As will be appreciated, the resilient biasing arrangement  147  may take any number of different forms and may be mounted in a number of different ways to achieve the desired biasing of the hook  141 . 
     The bolt  148  may, in some embodiments, comprise an elongate shaft  1481  with a distal end which may include one or more inclined surfaces (and which may be generally cone shaped) to ease the receipt of the bolt  148  by the bolt receiving aperture  1412  and the further bolt receiving aperture  1431 . The elongate shaft  1481  may be attached to a shuttle  1482  of the bolt  148  which is configured for movement with the elongate shaft  1481 . The shuttle  1482  defines one or more (which may be two or three) padlock receiving apertures  1483 . In some embodiments, the shuttle  1482  is a generally planar member. 
     The bolt  148  has a bolt axis which extends along a central longitudinal axis of the elongate shaft  1481 . The bolt  148  is moveable along the bolt axis between a position in which a portion of the bolt  148  (e.g. a portion of the elongate shaft  1481 ) is received by the bolt receiving aperture  1412  and the further bolt receiving apertures  1431  (the ‘bolted position’) and a position in which a part of the bolt  148  does not extend through at least the bolt receiving aperture  1412  and may not extend through at least one of the further bolt receiving apertures  1431  (the ‘unbolted position’). 
     With the bolt  148  in the bolted position, the one or more padlock receiving apertures  1483  is aligned with one or more corresponding further padlock receiving apertures  1491  which are defined by a padlock plate  149 . 
     The padlock plate  149  is mounted to the main body  142  and is generally immoveable with respect thereto. 
     The one or more padlock receiving apertures  1483  and the one or more further padlock receiving apertures  1491  are configured to receive a lock member  1501  of a padlock  150  to lock the bolt  148  with respect to the main body  142 . 
     An end portion of the shuttle  1482  away from the elongate shaft  1481  may include a handle portion which is configured to be grasped by a user to allow manual movement of the shuttle  1482  with respect to the padlock plate  149 . The handle portion may expend generally perpendicular to the elongate shaft  1481 . 
     The padlock plate  149  may include one or more bolt guide members  1492  which define one or more guide apertures  1493  which are each configured to receive a portion of the bolt  148  (e.g. a portion of the elongate shaft  1481 ) and to guide movement thereof with respect to the main body  142 . The one or more guide members  1492  may, in some embodiments, be attached to the main body  142  in addition to or as an alternative to being part of the padlock plate  149 . 
     In some embodiments, the shuttle  1482  is configured to be at least partially supported by the padlock plate  149  and may be located generally above or generally below (in a normal orientation) the padlock plate  149 . In some embodiments, one or more additional support elements (not show) may be provided to support, at least in part, the shuttle  1482 . The one or more additional support elements may be secured to the main body  142  and may be integrally formed therewith or attached thereto. 
     In some embodiments, the shuttle  1482  and/or the padlock plate  149  includes a lock  150   a . A body of the lock  150   a  may be secured to the shuttle  1482  or padlock plate  149  and a locking portion of the lock  150   a  may be configured to engage, selectively, the other of the shuttle  1482  and padlock plate  149  to inhibit movement of the shuttle  1482  with respect to the padlock plate  149  in a locked state (in other words to lock the shuttle  1482  with respect to the padlock plate  149 ) or to allow such movement in an unlocked state. 
     The lock  150  a may include a keyhole  150   b  or other actuator with which the lock  150   a  can be moved from a locked to an unlocked state. The keyhole  150   b  or other actuator may face upwardly (in a normal orientation) for ease of access. A key may be provided and configured to interact with the keyhole  150   b  or other actuator to cause the lock  150   a  to transform between the locked and unlocked state. In some embodiments, the body of the lock  150   a  may have a generally cylindrical form. In some embodiments, the body of the lock  150   a  may be integrally formed or welded to (or otherwise immovably secured) to the shuttle  1482  or padlock plate  149 . In some embodiments, the body of the lock  150   a  includes a slot through which a portion of the shuttle  1482  or padlock plate  149  may pass when the lock  150   a  is in an unlocked state. 
     As will be appreciated, a lock  150   a  which is generally permanently (i.e. immovably) mounted to the shuttle  1482  and/or the padlock plate  149  may be viewed as an ‘integral lock’ (although such a lock may not necessarily be integrally formed therewith). 
     In some embodiments, one or more further protective plates  1432  may be provided which are each configured to restrict or inhibit access to one or more parts of the toolbox lock  1 . In some embodiments, a first of the pair of protective side plates  143  which is remote from the padlock plate  149  may carry and/or be attached to two further protective plates  1432  which are each positioned towards a respective longitudinal edge of the main body  142 . A first of the further protective plates  1432  may be positioned adjacent an end of the pin  146  and a second of the further protective plates  1432  may be positioned adjacent a further bolt receiving aperture  1431 . In some embodiments, first and second further protective plates  1432  are located either side of a further bolt receiving aperture  1431 . 
     In some embodiments, an elongate protective plate  1432   a  is provided which is configured to protect at least part of the elongate shaft  1481  from interference. The elongate protective plate  1432   a  may be aligned with and/or even formed with (or secured to) the padlock plate  149  or shuttle  1482 . One or more further such elongate protective plates  1432   a  may be provided also configured to inhibit interference with the elongate shaft  1481 . The or each elongate protective plate  1432   a  or further elongate protective plate may have a longitudinal axis which is generally parallel to and spaced apart from a longitudinal axis of the elongate shaft  1481 . The elongate protective plate  1432   a  and/or further elongate protective plate may carry the resilient biasing arrangement  147  in some embodiments. 
     In some embodiments, the pin  146  has a generally cylindrical shape with a head which is shaped and size such that the head cannot pass through the one or more mounting apertures  144 . The pin  146  is configured to be mounted such that a portion of the pin  146  is immediately adjacent the first of the further protective plates  1432 . That portion of the pin  146  may include a flattened portion which is configured such that it conforms to a surface of the first further protective plate  1432  and to abut thereagainst. As will be appreciated, in such embodiments, rotation of the pin  146  with respect to the further protective plate  1432  is inhibited or substantially prevented by the abutment of the flattened portion of the pin  146  and the further protective plate  1432 . 
     The pin  146  may define a securing aperture  1461  generally remote from the head and towards the flattened portion. The securing aperture  1461  may extend through an entire width (e.g. diameter) of the pin  146 . With the rotation of the pin  146  inhibited or substantially prevented—as discussed above—the securing aperture  1461  may be generally aligned with a corresponding securing aperture  1421  through a depth of the main body  142 . Accordingly, a split pin or other securing member may be inserted through the securing aperture  1461  and corresponding securing aperture  1421  to inhibit or substantially prevent removal of the pin  146  from its mounted position. 
     The hook  141 , in some embodiments, comprises a planar elongate member with a pair of opposing longitudinal edges coupled by an end edge at a proximal end of the hook  141 . Ata distal end of the hook  141  is a hook member  1413 . 
     The hook member  1413  at least partially defines a hook recess  1414  between an internal edge of the hook member  1413  and a body of the hook  141 . The hook recess  1414  is configured to receive a part of the toolbox  100  or an attachment thereof (generally as described herein). 
     An outer edge of the hook member  1413  from the upper longitudinal edge to a front edge of the hook  141  may be a curved. 
     The hook recess  1414  has an entrance which is defined between the hook member  1413  and a part of the hook body. An entrance portion of the hook member  1413  adjacent the entrance to the hook recess  1414  may be shaped so as to aid movement of a part of the toolbox  100  or an attachment thereof into the hook recess  1414 . Accordingly, the entrance portion may be curved or angled from the front edge of the hook  141  towards the hook recess  1414 . 
     An exit portion of the hook member  1413  adjacent the entrance portion is also, in some embodiments, shaped so as to aid movement of a part of the toolbox  100  or an attachment thereof out of the hook recess  1414 . 
     A retaining portion of the hook member  1413  adjacent the exit portion and remote from the entrance portion may be shaped to retain a part of the toolbox  100  or an attachment thereof when the hook  141  is in the locking position of the operative condition. 
     The hook recess  1414  is at least partially defined by a body of the hook  141  (as discussed above). In particular, in embodiments, an angled edge of the body at least partially defines the hook recess  1414 . The angled edge is located such that it generally opposes the hook member  1413  across the hook recess  1414 . The angled edge is angled with respect to a longitudinal axis of the hook  141  that a part of the toolbox  100  or an attachment thereof driven against the angled edge will cause the hook  141  to move downwardly—against the biasing force of the resilient biasing arrangement  147  in applicable embodiments. As will be appreciated, the hook  141 , therefore, moves under this force into the locking position of the operative condition such that the bolt  148  may be moved into the bolted position. 
     With the hook  141  in the locking position of the operative condition, the part of the toolbox  100  or the attachment thereof is inhibited or substantially prevented from leaving the hook recess  1414  by the hook member  1413  (and, in particular, the retaining portion thereof). 
     Another form of part of the hook  141 , according to some embodiments of the invention is show in  FIG. 22 . 
     The hook  141  is held in the locking position by the bolt  148  in the bolted position. A padlock or other selective access lock may be provided. A portion of the padlock may be inserted through a padlock receiving aperture  1483  and a further padlock receiving aperture  1491  to secure the bolt  148  in a substantially fixed position with respect to the main body  142 —and keep the bolt  148  in the bolted position. 
     The bolt  148  may be moved to the unbolted position. Movement of the part of the toolbox  100  or attachment thereof away from the angled edge of the hook body will allow the hook  141  to move towards the engaging position of the operative condition (i.e. out of the locking condition) under the force applied by the resilient biasing arrangement  147 . 
     With the hook  141  in the engaging position, further movement of the part of the toolbox  100  or the attachment thereof towards the hook member  1413  will bring that part or attachment into engagement with the exit portion of the hook member  1413 . Further movement of that part or attachment in generally the same direction will cause the part or attachment to leave the hook recess  1414  through the entrance thereto. In some embodiments, the further movement forces the hook  141  upwardly away from the locking and engaging positions of the operative condition (generally towards the stowed condition but not into the stowed condition in some embodiments). 
     As will be appreciated, the hook  141  may be moved into the stowed condition by rotational movement of the hook  141  upwardly away from the engaging position. The hook  141  may then move linearly with respect to the pin  146  such that the pin  146  occupies a different part of the pin receiving aperture  1411  (as described above). 
     The hook  141  may be moved into the stowed condition when not in use. 
     This reduces the distance from which the toolbox lock  1  extends from the support structure—reducing the risk of tripping, damage to property, and damage to the toolbox lock  1 . 
     The support structure  200  to which the first and second lock bodies  13 , 14  are secured may be, for example a wall. In some embodiments, the first and second lock bodies  13 , 14  are secured to respective different support structures  200 . The or each support structure  200  may be a floor mounted member which extend upwardly from a floor surface—such as a post or pillar. 
     As will be understood, the part of the toolbox  100  or the attachment thereof which is received by the hook recess  1414  may be the second lock engagement member  12  or a part thereof. The second lock engagement member  12  may be of the same form as the first lock engagement member  11  described above. 
     Embodiments of the present invention allow a toolbox  100  to be secured to a support structure  200  to frustrate efforts, for example, to steal the toolbox  100 . The toolbox lock  1  is, therefore, in embodiments, a security mechanism. 
     As mentioned above, in some embodiments the second lock engagement member  12  is mounted to an axle of a castor  104   a  or other fixing element which is used to secure the wheel. In such embodiments, engagement of the first lock engagement member  11  with the first lock body  13  and then rotational movement of the toolbox  100  about the first lock body  13  and/or the first lock engagement member  11  (which may be rotation about the direction axis of the castor  104   a  to which the first lock engagement member  11  is mounted) will mean that the axle of the castor  104   a  to which the second lock engagement member  12  is mounted will be generally perpendicular to the hook  141  (i.e. generally parallel to the support structure and main body  142 ) as the second lock engagement member  12  approaches the hook  141 . In embodiments, the second lock engagement member  12  is configured such that, as it approaches the second lock body  14 , the second lock engagement member  12  extend towards the first lock body  13  (i.e. inwardly with respect to the toolbox  100 ) and the hook  141  may be located such that it is inwardly (or outwardly) located with respect to the castor  104   a  to which the second lock engagement member  12  is mounted. 
     The second lock engagement member  12  may enter the hook recess  1414  as described above to secure the second lock engagement member  12  to the second lock body  14  (and, hence, to secure to the toolbox  100  to the support structure). In particular, a portion along a length of the second lock engagement member  12  may abut the entrance portion of the hook member  141  and then move through the entrance of the hook recess  1414  (or may pass through the entrance of the hook recess  1414  without touching the entrance portion of the hook member  141 ). 
     The positioning of the first and second lock engagement members  11 , 12  may be such that engagement with the first and second lock bodies  13 , 14  results in the operation of one or more closure arrangements of the toolbox  100  being restricted. For example, the front face  101   a  of the toolbox  100  may face the support structure  200  (such as a wall). Accordingly, in such embodiments, not only is removal of the toolbox  100  inhibited but also access to the tools storage volume (or a part thereof) is inhibited by use of the toolbox lock  1 . 
     In some embodiments, the positioning of the first and second lock bodies  13 , 14  is determined by a dimension of the toolbox  100 . For example, in embodiments in which the first and second lock engagement members  11 , 12  are provided mounted to respective castors  104   a  of the toolbox  100 , the positioning of the first and second lock bodies  13 , 14  may be determined by the spacing of those castors  104   a  with respect to each other. 
     As will also be appreciated, the first and second lock bodies  13 , 14  ensure that the toolbox  100  is secured against rotation with respect to the support structure  200 . 
     According to embodiments of the invention, the engagement of the first lock body  13  and a part of the toolbox  100  or an attachment thereof occurs first. As will be appreciated, this engagement then restricts and guides the movement of the second lock engagement member  12  towards the second lock body  14  in such a manner that engagement is possible without additional alignment steps being necessary. 
     In some embodiments, the first lock body  13  is configured to be secured to a floor surface. 
     In some embodiments, the padlock plate  149  is located above the shuttle  1482  and in some embodiments the padlock plate  149  is located below the shuttle  1482 . In some embodiments, padlock plates  149  are located above and below the shuttle  1482 . 
     At least one of the one or more bolt guide members  1492  may act as a stop for the shuttle  1482  such then when the shuttle  1482  abuts the at least one bolt guide member  1492 , the bolt  148  is in the bolted position. 
     The first and second lock bodies  13 , 14  may be formed from steel or stainless steel. 
     In some embodiments, the first and second lock engagement members  11 , 12  can be retrofitted to an existing toolbox  100 . For example, the toolbox  100  may include a pair of castors  104   a  which include respective wheels secured by an axle bolt. Each lock engagement member  11 , 12  may be secured to the axle bolt (which may require temporary removal of the axle bolt or replacement thereof). In such embodiments, it will be appreciated that the toolbox  100  can be returned to its original state by removal of the first and second lock engagement members  11 , 12 —i.e. there is no or little damage to the toolbox  100 . 
     Some embodiment of the toolbox lock  1  may include a padlock. 
     As will be appreciated, the lock bodies  13 , 14  may be configured to receive an attachment of the toolbox  100  in the form of respective castors  104   a  or parts thereof. 
     The hook  141  is, of course, one example of a member which may be configured for engagement with a part of the toolbox  100  or an attachment thereto. 
     Embodiments of the present invention have been described with reference to a toolbox  100 . It will be apparent that all embodiments disclosed herein may be suitable for use in relation to other objects (in addition to or instead of a toolbox  100 ). In particular, embodiments of the present invention are suitable for use with an object with a ground engaging mechanism generally as described above in relation to the toolbox  100  (e.g. including one or more castors  104   a  or other forms of wheel). Such objects may define volumes suitable for the storage of other items (i.e. they may be containers)—such as surgical equipment, medical monitoring equipment, weapons, food, jewelry, documents, and the like. For example, the teachings presented above in relation to a toolbox  100  (and the toolbox lock  1 ) may apply equally to a surgical instrument trolley (and a surgical instrument trolley lock), a stand for medical equipment (and a stand for medical equipment lock), a gun cabinet (and a gun cabinet lock), a food trolley (and a food trolley lock), a safe or strongbox (and a safe or strongbox lock), and a filing cabinet (and a filing cabinet lock).
