f t 535491 Patents Form No. 5 Fee No. 4: $250.00 Pipers Central Ref:H/DH12-3016NZ PATENTS ACT 1953 COMPLETE SPECIFICATION Divided from NZ patent application No. 528433 After NZ Patent Appln Nos 535491 Dated : antedated to 24 September 2003 IMPROVEMENTS IN AND RELATING TO SECURITY MEANS FOR 30 LATCHING APPARATUS I Wayne Lionel Ace-Kirker, a New Zealand citizen of 204B Te Rapa Road, Hamilton, New Zealand, do hereby declare the invention for which I/we pray that a patent may be granted to me and 35 the method by which it is to be performed, to be particularly described in and by the following statement: IMPROVEMENTS IN AND RELATING TO SECURITY MEANS FOR LATCHING APPARATUS Technical Field The present invention is directed to improvements in and relating to security means for latching apparatus. In particular, the invention relates to aspects of the manufacture and operation of an improved security locking system for container and/or truck door latches or handles.

The security means incorporates features to enable a locking means to be fitted into a substantially tamperproof receptacle fixedly positioned relative to the container or truck door latch. The receptacle is so fixed, and a portion of the latching apparatus of the truck/door latch and a portion of the locking means co-operate, to thereby obviate problems of the lock or latch being removed, opened, or damaged, in unapproved attempts to access 15 the contents of the container or truck.

It is envisaged the locking means will include either an adapted single pin locking system whether as either or both a single pin combination lock and a single pin key lock which is enclosed within the receptacle, or a standard padlock co-operating with a hasp system of 20 the latching apparatus. Only approved individuals are provided with the means to open the lock and gain access to the contents of the container.

Where the lock is a single pin key or a standard key operated padlock option, individuals may only open the latching means on a container/truck door via use of the key. The 25 receptacle enclosing the lock provides greater security to the container/door than would be available by simply having a padlock, with or without means to protect the double pins of the padlock from being tampered with.

The single pin combination lock option obviates the need to carry, cut or arrange access to 30 separate keys for various individuals. Access to the container/truck contents is therefore dictated by opening the lock via a code which is changeable. 2 The single pin key and combination lock option alternatively provides a means where a key may be used by one individual, but knowledge of the code enables the lock to still be opened by another individual, or should the key be lost.

Whilst the invention is envisaged to have particular application in relation to securing means for the latching systems of containers, trucks and the like, it should be appreciated that this invention may be used in relation to securing the closure of any opening via use of this securing means. For example, this security mean for latching apparatus may be used or adapted for use with any type of door, latched gates or any other options where areas are 10 required to be accessed by any varying number of individuals but only as allowed. In addition, the invention may have applications outside this field.

Background Art When one looks to the transport and carrier industry there are numerous ways that openings, such as doors, or areas where articles are stored, are latched closed.

The latching apparatus for cargo doors of cargo carrying vehicles and shipping containers usually includes a handle which co-operates with a configured latch that maintains the 20 handle in a closed position whereby the doors to which they are attached also remain closed. To secure the cargo against theft or interference a locking system may be employed to prevent the handle being lifted and the door being opened. Additionally, a seal or the like may be included as a tamperproof alert means. It may be seen at a glance that damage to the seal indicates there has been an unapproved attempt to access the contents of the 25 container. Seals however, do little to actually prevent unauthorised access to the cargo.

Typically the locking means most commonly used include padlocks, or padlock and chain combinations. However, it is not difficult to cut through a padlock pin or a chain in order to gain access to the cargo.

To provide increased security for storage containers and the like, locking mechanisms may be adapted to limit the exposure of the lock. These are designed to minimise the likelihood of vandals or thieves being able to pry or break the lock open. Additional components of the locking mechanism - such as the handle of the door itself may also be encased within a 3 protective framework to prohibit tampering of the various components of the locking mechanism.

The above discussion has related to the provision of a security means for cargo containers 5 and the like. However, there are a number of instances where having a security means to limit access to authorised personnel alone would be beneficial. For example, access through gates on farms, or on residential, commercial, educational, recreational or industrial properties are other such situations. One of the most common situations faced by occupants/owners of a building or business premises is being able to arrange access to the 10 building/premises by selected individuals, yet without the security of the building/premises being compromised. Having a substantially tamperproof security means for an associated latching system which allowed restricted access to a selected area by selected individuals may be substantially beneficial.

For example in the motor industry there are several situations where an individual may need to access an area and/or access an item. Motor vehicle dealers, car rental providers, vehicle repairs and maintenance providers all face situations where cars are to be dropped off or picked up. Often the drop off or pick up is outside normal trading hours. Therefore, arrangements need to be made to enable the vehicle to be secured in an area until it is 20 collected or worked on. Boating or trailer maintenance or purchase is a similar situation. In any situation where access to an area to collect or drop off the vehicle is prevented outside of normal trading hours, the owner of the vehicle is limited to ensuring they are at the business when it is open, or employees may have to attend the site outside of work hours. Existing systems do not offer a flexible option to enable repeated use by a range of 25 individuals without potentially compromising the security of the clients', or the business' property.

Deliveries of articles to businesses are also often undertaken outside normal trading hours. Such deliveries (or pick-ups) again require access to an area which is generally restricted at 30 those times.

While the present invention has a number of potentially realisable applications, it is in relation to problems associated with existing systems that the present invention was developed. More specifically, it was with the problems associated with: 4 a) the lack of a readily available alternative securing system for achieving security of an enclosed area which includes latching means to be operated to gain entry, yet b) enabling access to that area, or the contents therein, by a range of unrelated 5 individuals; and c) otherwise having to supply a number of access keys, having to use locking systems that are vulnerable to being tampered with, or having to hide the access key which potentially undermines the area's security.

It was also with the problems of having existing systems that required an increasing number of parts, or labour intensive installation, in mind that the present invention was devised.

Having a simple system, capable of being easily installed would benefit those with preexisting latching systems requiring improved security means therefor. It would further 15 benefit those wishing to install such a system as part of a container, truck, enclosure and so forth.

It would be useful therefore, to have a security means for latching apparatus that fulfilled the above requirements and, in addition: a) Could enable access to the contents of the container, truck, enclosure, area and so forth, by separate individuals who have approval and instructions as to how to do so; and yet b) As soon as access was no longer to be made available to an individual the means of accessing the area, contents and so forth could be altered, yet access by approved individuals would be still available; and c) Was relatively securely configured and securely installed to reduce the likelihood of 30 successful attempts to force open the container and/or removal of property from an area; d) Could be linked to an alarm system as a further deterrent against unapproved attempts to access the area.

Ideally the present invention will also provide security means for a latching system which allows for substantially trouble free installation.

It would therefore be useful to have an invention that offered at least some if not all of the 5 advantages of the above proposed security means for latching apparatus. It is therefore an object of the present invention to consider the above problems and provide at least one solution which addresses a plurality of these problems.

It is therefore a further object of the present invention to at least provide the public with a 10 useful choice, or an alternative system.

Further aspects and advantages of the present invention will become apparent from the ensuing description which is given by way of example only. It should be appreciated that variations to the described embodiments are possible and would fall within the scope of the 15 present invention.

Disclosure of Invention According to one aspect of the present invention there is provided security means for latching apparatus, said security means including container means, attachment means and locking means, the locking means including a body and a locking pin, the container means being adapted to receive the body of the locking means and retaining same in an orientation to receive the locking pin and lock the locking means, the locking pin being adapted to co-25 operate with hasp means and/or optionally at least one portion of the latching apparatus, said container means being further adapted to co-operate with the attachment means capable of attaching the security means in the vicinity of the latching apparatus, said security means being characterised by access to the body of the locking means and the pin of the locking means when locked being minimised by the arrangement of the container 30 means, the latching apparatus and the attachment means.

Preferably the container means includes at least one substantially planar surfaces defining a front and optionally a back surface or at least a portion of a back surface; with at least two permanent surfaces substantially at right angles to the front and the back surfaces forming 6 the sides of the container means, and optionally at least two additional surfaces defining a top and a bottom each including apertures capable of receiving portions of the locking apparatus.

Preferably the container means is adapted to receive the body of the locking means. In the present invention the locking means includes a single pin key and/or combination lock, a standard padlock - whether keyed or combination. The interior of the container means optionally includes at least one, but preferably multiple bulkheads including apertures configured to the shape of the body of the lock. The bulkheads when present not only serve 10 to strengthen the container means, but also act as guides and retaining means to ensure the lock when inserted into the container means is firmly held in place to minimise movement of the lock. The arrangement of each bulkhead inside the container means is substantially at right-angles to the side walls of the container means and as such the bulkheads also serve as partitioning means. Alternatively, the bulkhead may be adapted to substantially form a 15 receptacle into which the lock body is placed.

Where the locking means is preferably of the single pin variety, it is preferable for the container means to include a bulkhead with which the locking pin is in a fixed arrangement to enable the locking pin to enter the lock body retained inside the container means, as well 20 as enabling the key hole or combination means to be accessed to lock and unlock the lock. Where the lock is a standard padlock used with hasp systems, the lock may co-operate with features of the container means to enable the pin of the padlock to be pressed into the lock body. The position of any apertures in the container means may therefore defined by the configuration of the lock itself and its entry point into the container means.

However, as can be appreciated the entry or exit of the locking pin into the lock body, or of the lock body into the container means can be at any location on the encasing container means. The orientation of the security means on the surface to which it is attached may also be variable. The preferred orientation may in turn be dictated for example, by the required 30 access to the key or combination point for locking and unlocking the lock, may be dictated by the configuration of the structure itself which limits the container means to a particular orientation, or may be dictated by the configuration of the latching apparatus. Other limitations may also be present which affects the orientation of the container means and/or the entry points in the container means for either or both the locking pin and the lock body. 7 The container means is preferably attached to the structure associated with the latching means. If the latching means is on a cargo vehicle or container, the latching means and hence the securing means are associated with the access door. Where the latching means is on a gate, a portion of either or both the latching means and the security means may be 5 attached to the gate, the supporting framework, or an adjacent structure.

It is preferable to attach the container means to the structure without the attachment means themselves being exposed to tampering. Therefore, it is preferable that the container means cover or include thereinside the means of attaching the security means to the structure. 10 However, typical attachment means such as coach bolts, screws and the like need to be easily accessible for fitting the container means to the structure in the first instance.

In yet other embodiments, the attachment of the container means may include some form of attachment means external of the container means body, but arranged in such a manner that 15 it enables the container means to be fixed in place and be secure. This may entail additional co-operation of the container means with other features of the latching means, such as latching hasp means.

To address this problem, the container means of a preferred embodiment of the present 20 invention co-operates with an attachment bracket. The attachment bracket includes at least one aperture for receiving attachment means to secure the attachment bracket to the structure the security means is to be used with. At least one coach bolt or other form of attachment means passes through the aperture in the attachment bracket and secures the attachment bracket to the structure. However, to ensure the container means is able to cover 25 the heads of the attachment means, the container means is preferably moveable relative to the attachment bracket. In described preferred embodiments, the container means is preferably slideable relative to the attachment bracket. Accordingly, the container means may slide up or down relative to the attachment bracket to expose the attachment aperture. The bolt or similar is fitted through the attachment aperture and into the structure and 30 tightened. The container means is then slid back to the original place and covers the head of the bolt. Provision of a stop means on either or both the container means and the attachment bracket prevents the container means from sliding off the attachment bracket when the attachment bracket and co-operating container means are attached to a structure. 8 However, in yet an alternative embodiment, the container means may be pivotably attached to the bracket, such that the container means may be operated between an opened and a closed orientation. For example, appropriate hinge systems or other equivalent means may therefore be used with, or adapted for use with this embodiment. The container means may 5 therefore be pivoted open for access to the latching apparatus and be closed, in conjunction with the locking means, to secure the latching apparatus.

The attachment bracket may be substantially elongate. The dimensions of the attachment bracket however, preferably equate to the dimensions of the container means, such as the 10 length of the container means. In some embodiments more than one bracket means may be arranged in series. In a preferred embodiment allowance may be included for the thickness of portions of the latching apparatus secured by the security means and to accommodate other features of the security means, such as the hasp means and the locking pin arrangement.

Given that the attachment bracket is substantially elongate two or more attachment means, such as a coach bolt or similar may be used. Where two attachment means are preferred they may each be located at opposite distal ends of the attachment bracket. As such, the one attachment means may be inaccessible once the security means is either or both affixed to 20 the structure and locked in place, as it is preferably covered by the container means. The second attachment means may be used to attach the hasp means to the attachment bracket. The hasp means may be designed in a similar manner as the container means such that it too is able to cover the head of the attachment means once the security means is affixed to the structure. In such an embodiment the length of the attachment bracket may need to 25 make allowance for the hasp means to be moved out of the way of the handle, to enable the latched handle to be unlatched and vice versa.

In some embodiments however, where the security means is designed to replace existing structures, on cargo vehicle or container doors, the placement of the attachment means may 30 be dictated by existing apertures in the walls of the structure. Accordingly, the head of the upper attachment means may be exposed. Nevertheless, the configuration of the present invention enables security of the latching means to be uncompromised. 9 For example, even if an unauthorised attempt was made to access the contents of a truck, container, enclosed area, by use of a gas axe or other cutting tool to attempt to cut the exposed head of the attachment bolt associated with the hasp means, access will still be prevented by virtue of the remaining portions of the security means. For example, the locking pin will still remain in place in the lock body. Further, the hasp means may be additionally configured to be unable to rotate, be lifted off or removed from its close association with the locking pin, even though the bolt attaching it through the attachment bracket has been cut. Thus the locking means still secures the latching apparatus in a closed and locked arrangement.

In some embodiments where there is attachment means that attach the hasp means to the attachment bracket, these may be separate from an additional hidden attachment means in the vicinity of the hasp means, to attach the attachment bracket to the structure.

Selecting the material from which the security means is manufactured can further assist in the deterrent effect of the security means. For example, manufacturing the security means and all its component parts thereof from stainless steel would require an unauthorized party to avail themselves of special cutting tools as opposed to simply a gas axe, or a hacksaw.

Having the latching means and its attachment components also manufactured from stainless steel would further enhance the security feature of this invention. Accordingly, the present invention extends also to improving the features/components of the latching apparatus and its attachment to the structure. For example, a slidable cover similar in operation to and attachment of the container means of the security means, may be used to cover vulnerable 25 portions of the latching apparatus and its components.

In various embodiments, the configuration of the container means and its location relative to the point of attachment of the handle of the latching means may in itself operate as an obstacle to prevent damage to the latching apparatus and/or its attachment to the structure, 30 in unauthorised attempts to access the contents of the container, truck, area.

Further, it is preferable that the locking means of the present invention not be vulnerable. Accordingly, the preferred lock is security proof in that it is not possible to drill the lock in an attempt to damage the lock and open it.

Further, it is a preferred design feature of the locking means that where a single pin key lock, or a standard keyed padlock, is used the key can not be removed from the lock unless the locking pin is in place and secured. This provides two benefits in that the operator knows that the lock is secure if the key can be removed, yet the operator can not misplace 5 the key when the lock is opened.

Where the present invention is used in relation to the latching means on a truck door or container door allowances have to be made for the structural thickness. The walls of these structures may vary in thickness and strength depending on the materials they are made 10 from, the stresses they face during transport and the contents they house inside. For example, some trucks have standard thickness metal doors. The attachment bracket with container means may therefore be attached via use of a standard coach bolt or the like through the door structure. However, where insulated trucks are concerned the thickness of the wall and the internal materials used may limited such direct bolting. In fact, it may be 15 necessary to include a longer bolt shaft, with a tension plate on the internal face of the door to ensure appropriate attachment of the bracket and the container means.

As previously mentioned, in there is a preferred embodiment of the present invention where the hasp means is also attached to the attachment bracket. Preferably the hasp means is 20 located at the opposite distal end of the attachment bracket to the container means. However, other locations of the hasp means may also be relevant. Preferably the hasp means is operable between a position enabling the handle of the latching means to be opened, and a position to restrict opening of the handle of the latching means. In one preferred embodiment the hasp means is rotatable. In other embodiments the hasp means 25 may also be slidable, or may pivot in order to operate between these two positions.

In yet other embodiments, the hasp means may be simply part of the latching means and as such be located relative to the latching handle, or separate therefrom and instead be associated with its own staple through which a padlock or locking pin may be inserted to 30 lock the hasp means in a locked position.

The hasp means and/or the container means may also preferably include a stop. The stop is configured such that when the hasp means or the container means is moved to a position to restrict opening of the handle of the latching means the aperture of the hasp means is 11 substantially aligned with the portion of the body of the lock that receives the locking pin or padlock shackle. Thus, this configuration improves the ease with which the locking pin or the padlock shackle is aligned with and inserted into the lock body.

Where the hasp means co-operates with handle portion of the latching apparatus, the hasp means preferably includes a body portion and an attachment portion. The body portion includes an aperture capable of receiving the locking pin or shackle of the locking means therethrough. The attachment portion is associated with attachment of the hasp means to the attachment bracket and/or the structure. The aperture of the hasp means is preferably 10 designed to have minimal tolerances. Ensuring snug co-operation between the aperture and the locking pin minimises leverage opportunities in unauthorised attempts to damage the security means and gain access to the truck, container, or area contents.

Where the hasp means is associated with its own staple portion, both the hasp and the staple 15 means will preferably include appropriately positioned apertures and attachment means to enable co-operation of the hasp and staple and to enable the locking means to be used therewith.

Either or both the hasp means and the container means may also include provision for the 20 attachment of a security seal. As previously mentioned, a security seal does not prevent attempts to tamper with the security means, but rather alerts to unauthorised or incidental attempts to open the security means.

Preferably the hasp means is raised to enable the handle of the latching means to be moved 25 relative to the receiving portion of the latching means. On the other hand, when the handle is in contact with the receiving portion, the hasp means is moved to its retaining position. In this position the hasp means is available to receive the locking pin of the locking means. Accordingly the hasp is preferably configured to be adapted to receive the pin is a substantially snug fit.

In one embodiment, the head of the locking pin is configured to complement the shape of the hasp aperture such that when inserted through the hasp aperture, the head of the locking pin is flush with the surface of the hasp means and provides no access to enable a hacksaw blade to reach or cut the shaft of the locking pin. 12 In other embodiments however, the body of the hasp means, at least adjacent the locking pin aperture, may be raised above the head of the locking pin, such that the head of the locking pin is recessed when the shaft of the locking pin is inserted through the hasp aperture.

In yet another preferred embodiment, the single pin is fixedly connected to a portion of the bracket means.

Preferably the locking pin is configured to be received into the body of the locking means 10 in a particular arrangement. The configuration of the head of the locking pin to complement the surface configuration of the hasp means enables the locking pin to always be inserted through the hasp aperture and into the body of the lock appropriately.

Before passing into the lock body, the shaft of the locking pin may also pass through 15 apertures in any one or more of the handle of the latching means, the receiving portion of the latching means and the staple of the hasp means. Again the configuration of the apertures ensures a snug fit and minimises access to the shaft of the locking pin via a hacksaw blade or the like. The front and the sides of the container means also extend around the hasp-pin-latch connection to minimise accessibility. The lock body may also be 20 indented in the container means to prevent protrusion of the lock from the container means which might otherwise attract attempts to damage the lock, and/or cause the lock to be vulnerable to the accumulation of road dirt in the locking mechanism thereby interfering with the functioning of the lock.

In addition, where the securing means is to be used on trucks or other road vehicles, the container means may also include a bottom to be push fitted or similar, to reduce entry of road dirt into the body of the lock which may interfere with the operation of the lock. Alternatively, a cap may simply be placed over the end of the lock itself.

As may be appreciated, the body of the container means may be adapted to receive any shape of handle of a latching means. Such adaptation may simply be by virtue of cutting a different profile out of the sides of the container means to ensure the handle fits snugly against the receiving portion of the latching apparatus. The configuration of the container means is chosen to ensure the locking pin may pas through the hasp aperture and apertures 13 in the latching apparatus and yet be in close proximity to the lock body in the container means, to effect a snug interconnection.

The advantages of the security means of the present invention include the ability to 5 transport goods from one area to another via truck, or container. The single pin lock enables the dispatching person to lock the lock with a key and/or combination code. The contents of the truck or container would then not be accessible until it arrives at its destination where another individual may access the contents by use of a key and/or combination code. In some instances, the combination access code may not be advised until arrival of the truck or 10 container at its destination and may be obtained via phone call or written/coded message. The combination may then be changed for use with another cargo. The combination is selectable and changeable to enable access to the interior of the container and the contents therein, only by selected individuals and for a specific time duration.

Preferably the distance the container means of the security means extends from the back of the truck or container is controlled so as to not impact on the ability to stack or handle the containers without damaging the security means.

Preferably, the security means is configured to complement the features of the surface to 20 which it is attached. In preferred embodiments the container means, hasp means and bracket means are manufactured from stainless steel which has been laser cut to the preferred configuration. The preferred thickness of the stainless steel is 4ml to 6 ml, but other thicknesses may be used. Further, other materials and manufacturing techniques may be employed without deviating from the scope of the present invention.

For the purpose of this specification, latching apparatus shall mean and include, but not be limited to, any fastening for a gate or door or the like which is used to bar access to an area. The latching apparatus may include a bar (straight or otherwise) or similar moving element that may be slid, lowered, rotated, pivoted and so forth into a receiving portion such as a 30 groove, hole, hasp, eye and so forth in order to effect retention of the door, gate, screen or the like in a closed position. The bar or the receiving portion may be attached to any one of the door, gate and so forth, or to the surrounding structure or to an adjacent frame or the like. 14 For the purpose of this specification the term "hasp means" is used to describe and shall include any means which is able to receive a portion of a locking means and co-operates with a portion of the latching means and the locking means in such a manner as to maintain the latching means either or both closed and secured/locked. The hasp means is preferably 5 capable of operating between a fastening and an unfastening position. To effect such movement the hasp means may be capable of pivoting, rotating, sliding and so forth. This definition is to be interpreted broadly and should not be limited only to the described features herein.

For the purpose of this specification, the locking means is additional means for securely affixing the bar of the latching means in a closed position and in an improved substantially tamper-proof manner to address the above mentioned problems of prior art systems in response to which the present invention has been designed.

Therefore, to secure the latching apparatus in a closed mode the latching apparatus either or both co-operates with and includes locking means. The locking means is used to prevent access to the contents of the container, area, enclosure and so forth.

In preferred embodiments of the present invention as previously mentioned, the locking means includes preferably a single pin lock, but includes an embodiment which can take a standard padlock shackle. Whilst a single pin key lock may be employed in preferred embodiments, this does not preclude the use of a single pin combination lock, or a combined single pin key and combination lock.

For the purpose of describing the present invention in this specification the lock may be substantially the same term as, or an adapted form of, the single pin lock described in the applicant's New Zealand Patent Application No.528386. As therefore defined, the word "pin" is used to describe any rod of substantially strong material which operates potentially as a key in a lock system. The pin is a locking pin which is accordingly slid into the lock body where it engages with mechanisms of the lock and is retained in position until released by means appropriate to opening the lock. Where the single pin lock includes a combination means for releasing the locking pin of the lock, the word "combination" is used to describe and include a code, whether it includes a system of numbers and/or letters, entered by means of push pad or tumbler systems. Use of the correct combination releases the locking pin and thus opens the lock and provides access to the contents of the container, area, and so forth. The term "pin" is also extended to cover a typically shackle of a padlock, where a portion of the shackle operates as the locking pin for the purpose of the present invention.

Whilst also described in this specification that the single pin lock is encased in the container means, it should be appreciated this does not limit the use of the lock to only encasement type applications. Typically locks are encased to minimise their vulnerability to interference by unapproved persons. The security means of the present invention benefits 10 from having the lock internal of the container means. However, the single pin lock may be manufactured to minimise any vulnerability inherent in currently available locks and as such would not require the lock to be encased for alternative applications.

The benefit of the use of a locking pin with a combination option as opposed to a traditional 15 key, is that the locking pin may be retained in place in the lock at all times and be engaged or disengaged from the lock to secure or open the lock as required, without the need for yet another separate key which needs to be made accessible, or may be lost. Such a system also has advantages over traditional padlocks, which may be opened via the use of bolt cutters, hacksaw blades and so forth.

Another benefit of a combination lock is that it enables the combination of the pin-combination lock to be selected, registered in the lock as required for a particular person to have access to the contents of the security container, but it may then be changed to prevent access once the purpose of that individual having access has expired. Having a changeable 25 combination enables access to the interior of a truck, container or area and the contents thereof, only by selected individuals for any preferred specific time duration.

In preferred embodiments of the present invention a single pin key lock is used. However, this does not limit the use of a single pin combination lock, a single pin key and 30 combination lock, or other keyed or combination systems, provided they are compatible with the overall concept of lock as herein described for use with the security means.

Further, where a single pin combination is used provision is made to enable the combination of the lock to be changed as required. The lock may therefore be removed 16 from the container means, the combination reselected and the combination lock is then returned to its compartment in the container means. Therefore, where the locking means used includes a combination system, there is preferably provision in the lock body itself to a means by which the combination of the lock may be changed. For example, a key or 5 screw may be required to be released. The combination tumblers may then be reset to a new entry combination. Once this has been achieved, the screw or key is returned to its original positions and the new combination is set. Various systems for changing the combination are however available and may be used with, or adapted for use with, a single pin combination lock option of the present invention.

As also mentioned previously, firm retention of the lock is also important to ensure the locking pin or portion of the shackle can be aligned with and inserted into the complementary aperture in the body of the lock itself. Movement of the body of the lock may in some prior art systems cause the pin to become bent and reduce both the effectiveness and the life of the lock. Lateral movement of the pin makes the alignment process less direct and may cause wear in the shaft of the pin. Preferably, the locking pin is made of stainless steel to strengthen the locking pin and prevent bending of or damage thereto.

Preferably, the body of the lock is located within the container means. Preferably a compartment allowing retention of the lock is provided. As previously described where there are bulkheads, the bulkheads of the compartment include apertures configured to complement the shape of the lock body. The bulkhead apertures may be adapted to enable a larger or smaller lock to be used if required.

Further, to address problems which may exist in prior art systems, the present invention which uses a fixed pin preferably relies on the positioning of the locking pin as an alignment means. The alignment means is configured to ensure the locking pin may only enter the body of the lock in one orientation and with little allowance for lateral movement of the pin.

With reference to the present invention the security means for latching apparatus herein described has preferable application in transportation industries, such as on trucks or 17 containers. However, the security means may be adapted for use in any situation where there is a need for a security of a container, area or enclosure.

According to another aspect of the present invention, there is provided a method of 5 manufacturing a security means for latching apparatus, said security means including container means, attachment means and locking means, the locking means including a body and a locking pin, the container means being adapted to receive the body of the locking means and retaining same in an orientation to receive the locking pin, the locking pin being adapted to co-operate with at least one portion of the latching apparatus, said container 10 means being further adapted to co-operate with the attachment means capable of attaching the security means in the vicinity of the latching apparatus, said security means being characterised by access to the body of the locking means and the pin of the locking means when locked being minimised by the arrangement of the container means, the latching apparatus and the attachment means.

According to another aspect of the present invention, there is provided a method of a locking security means for latching apparatus using locking means, said locking means including a single pin lock, said security means including container means and locking means, the locking means including a body and a locking pin, the container means being 20 adapted to receive the body of the locking means and retaining same in an orientation to receive the locking pin, the locking pin being adapted to co-operate with the hasp means and/or at least one portion of the latching apparatus, said container means being further adapted to co-operate with attachment means capable of attaching the security means in the vicinity of the latching apparatus, said security means being characterised by access to the 25 body of the locking means and the pin of the locking means when locked being minimised by the arrangement of the container means, the latching apparatus and the attachment means.

The present invention is differentiated from many existing products by virtue of its 30 attachment means, its hasp means and its locking means. Although variations to the dimensions of the security means may be desirable depending on the latching apparatus with which it is to be used. 18 In addition, it should also be appreciated that given the emphasis on security, the present invention may be interconnected with a vehicle's or building's security alarm system, so in the event that the security means or the latching apparatus should be tampered with, the alarm system would be activated. There is a range of alarm systems available in the market 5 and prior art. The present invention may be adapted for use with said alarm systems. However, it will be appreciated by a person skilled in the art, that the adaptations and interconnections required may vary between alarm systems and whilst known to a person skilled in the art, such detail of prior art alarm systems is not the ambit of the present specification.

It should be appreciated that the present invention lends itself to more than one application. It should further be appreciated a variety of different embodiments, uses, and applications of the present invention therefore exist even within the ambit of the above described security means system. An embodiment of the present invention will now be given by way 15 of example only, to help better describe and define the present invention. However, describing the specified embodiment should not be seen as limiting the scope of this invention.

Brief Description of Drawings Further aspects of the present invention will become apparent from the following description, given by way of example only and with reference to the accompanying drawings in which: Figures la-d are diagrammatic representations of the security means for latching 25 apparatus adapted for use with a standard padlock in accordance with one preferred embodiment of the present invention; and Figure 2a-g are diagrammatic representations of the security means for latching apparatus adapted for use with a fixed single pin locking system in 30 accordance with another preferred embodiment of the present invention.

Best Modes for Carrying Out the Invention 19 With reference to the diagrams (Figures la to 2g) by way of example only, there is provided security means (generally indicated by arrow (1)) for latching apparatus.

Whilst in this description the security means is described with reference to securing 5 latching means of trucks or containers primarily, it should be appreciated this invention may have applications outside this field and be used for other securing latching means for areas, enclosures, buildings, farm paddocks and so forth.

Figures la to Id illustrate one embodiment of the security means 1 for latching apparatus. 10 Figure la illustrates a front view of the container means 3. Figure lb illustrates a side view of the container means3 and the structural surface 4 with which the container means is used. Figures lb and lc illustrate a top and bottom view, respectively of the container means. The container means 3 is designed to co-operate with stop means 9 attached to either bracket means or is directly attachable to portion of the structural surface 4.

The locking means for use with this embodiment would typically be a standard padlock, whereby the shackle of the padlock passes through the staple of hasp means, or receiving portion and/or handle of latching apparatus. For example, the latching apparatus may be a lifting handle and a latching receiving portion of a door latch for a truck or cargo container.

The container means includes at least one substantially planar surfaces defining a front 3a (and in some embodiments may optionally include a second or partial surface defining a back surface) respectively. The container means also includes at least two permanent surfaces substantially at right angles to the front (and the back surfaces) forming the sides 25 3c of the container means, and at least two optional additional surfaces defining a top 3d and a bottom 3e. Where relevant, apertures capable of receiving portions of the locking apparatus are included.

The container means 3 is adapted to receive a lock (not shown) and retain it in an 30 orientation to receive the shackle in a locked position after co-operation of the shackle with appropriate staple or hasp means. This is achieved by the inclusion of a compartment or spaced apart bulkheads 6 which serve to strengthen the container means. The bulkheads 6 include apertures 6a configured to complement the shape of the lock body. In some instances the apertures may be configured to enable the lock body to only be inserted in the right way. The arrangement of each bulkhead inside the container means is substantially at right-angles to the side walls 3 c of the container means and as such the bulkheads also serve as partitioning means.

The container means 3 is also adapted to co-operate with attachment means 7 capable of attaching the security means 1 in the vicinity of the latching apparatus and attached to the structure associated with the latching apparatus. Accordingly, the container means cooperates with an attachment bracket 8. The attachment bracket includes at least one aperture 8a for receiving attachment means 7 to secure the attachment bracket to the structure the security means is to be used with. To ensure the container means 3 is able to cover the heads of the coach bolt, the container means is able to move relative to the attachment bracket. The container means is adapted at 3 f to include a hinge portion to allow this movement to occur.

In the illustrated embodiment the container means 3 hinges relative to the attachment bracket 8 to expose the attachment aperture 8a. The attachment means is fitted through the attachment aperture and into the structure and tightened. The container means is then hinged back to the original place and covers the head of the attachment means. A stop means 9 on either or both the container means 3 and the structural surface to prevent the 20 container means from being loosely secured.

Where the present invention is used in relation to the latching means on a truck door or container door allowances have to be made for the structural thickness. The attachment bracket with container means may therefore be attached via use of a standard coach bolt or 25 the like through the door structure. However, where insulated trucks are concerned the thickness of the wall and the internal materials used may limited such direct bolting. In fact, it may be necessary to include a longer bolt shaft, with a tension plate on the internal face of the door to ensure appropriate attachment of the bracket and the container means.

The attachment bracket 8 in the illustrated embodiment is substantially elongate. Therefore, two attachment means 7 are used, each located at opposite distal ends of the attachment bracket. The attachment means 7 are typically inaccessible once the security means is affixed to the structure as it is preferably covered by the container means. Second attachment means 7a may be used to attach the stop means 9 to the structure. 21 In Figures 2a to 2g, Figure 2a illustrates a front view of the container means, Figure 2b illustrates a side view of the container means and Figures 2c and 2d illustrate a top and bottom view respectively of the container means.

Figure 2e illustrates a side view of the bracket means, Figure 2f illustrates a front view of the bracket means and Figure 2g illustrates the container means and bracket means in a cooperating configuration.

The configuration of the security means also includes provision for the attachment of a 10 security seal, such as a bolt seal. Whilst a security seal does not prevent attempts to tamper with the security means, it can alert to unauthorised or incidental attempts to open the security means. The seal may be wholly, partially, or not protected by the security means depending on the regulatory requirements associated with seals of particular types in particular instances of use.

In this embodiment, the lock body again fits within a compartment or is held in place by appropriately configured bulkheads in the container means. However, a locking pin is secured to stop means 9 in such a position so as to enable the locking apparatus to be locked simply by pushing the lock body onto the locking pin. The arrangement of the 20 locking pin requires the lock body to be oriented appropriately otherwise the lock pin will not be able to enter the lock body. Before passing into the lock body, the shaft of the locking pin may also pass through apertures in either or both the handle of the latching means and the receiving portion of the latching means. Again the configuration of the apertures ensures a snug fit and minimises access to the shaft of the locking pin via a 25 hacksaw blade or the like.

In this embodiment, there are also potentially two bracket means 8. One associated with the container means and one associated with the structural surface. The container means bracket co-operates with the bracket on the structural surface in such a manner that the 30 interconnection point(s) are substantially inaccessible to a hacksaw blade or leverage means, which may be used in unauthorized attempts to open the security means.

The front 3 a and the sides 3 c of the container means also extend around the hasp-pin-latch connection to minimise accessibility. The lock body is also indented in the container means 22 to prevent protrusion of the lock from the container means which might otherwise attract attempts to damage the lock, and/or cause the lock to be vulnerable to the accumulation of road dirt in the locking mechanism thereby interfering with the functioning of the lock. Where the securing means is used on trucks or other road vehicles, the container means 5 may also include a bottom to be push-fitted or similar, to reduce entry of road dirt into the body of the lock which may interfere with the operation of the lock. Alternatively, a cap may simply be placed over the end of the lock itself (not shown).

The body of the container means may be adapted to receive any shape of handle of a 10 latching means by virtue of cutting a different profile 11 out of the sides 3c of the container means to ensure the handle fits snugly against the receiving portion of the latching apparatus.

With reference to the present invention the security means for latching apparatus herein 15 described has preferable application in transportation industries, such as on trucks or containers. However, the security means may be adapted for use in any situation where there is a need for security of a container, area or enclosure. A variety of different embodiments, uses, and applications of the present invention therefore exist, even within the ambit of the above described security means system.

Variations to the dimensions of the security means may also be desirable depending on the latching apparatus with which it is to be used. However, the present invention is differentiated from many existing products by virtue of its container means and attachment bracket inter-relationship, its hasp means and its locking means.

In addition, whilst not illustrated in the attached figures, given the emphasis on security, the present invention may be interconnected with a vehicle's or building's security alarm system, so in the event that the security means or the latching apparatus should be tampered with, the alarm system would be activated.

It should also be understood that the term "comprise" where used herein is not to be considered to be used in a limiting sense. Accordingly, 'comprise' does not represent nor define an exclusive set of items, but includes the possibility of other components and items being added to the list. 23 This specification is also based on the understanding of the inventor regarding the prior art. The prior art description should not be regarded as being an authoritative disclosure of the true state of the prior art but rather as referring to considerations in and brought to the mind 5 and attention of the inventor when developing this invention.

Aspects of the present invention have been described by way of example only and it should be appreciated that modifications and additions may be made thereto without departing from the scope thereof as defined in the appended claims. 24
