AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT Name of Applicant: DICKORY RUDDUCK Actual Inventor: DICKORY RUDDUCK Address for Service: Chrysiliou Law Patent and Trade Mark Attorneys 15-19 Parraween Street Cremorne NSW 2090 Invention Title: Fixing And Release Systems The following statement is a full description of this invention, including the best method of performing it known to me/us: \\scTvre\docs\patCnts\applicalions\I 5838.docp 15858 1 FIXING AND RELEASE SYSTEMS TECHNICAL FIELD This invention lies in the field of fixing and/or release systems for a myriad of products and applications. This invention also relates to connectors for use in s fixing and release systems. BACKGROUND ART The need to fix one element to another, such as a panel to a stud, has given rise to a large technology relating to fasteners. Primitive versions, such as nails and screws, are labour intensive and have the drawback that the fixing means are visible 1o externally. It is desirable to fix one element to another so that the fixing means are not visible externally. This desirability may be based on aesthetic or economic reasons. For some applications, it may be desirable that the fixing means are not visible externally, for security purposes. Common construction practice is to provide a first fixing stage, followed by a 1s "final fix" stage. This is labour intensive and generally results in post-finishing. It is desirable to eliminate the need for the first fixing stage and to fix only after assembly has been completed. Further, common methods of fixing are rarely reversible without damage to the elements being fixed. It is desirable to devise a fixing system which, at least in 20 some aspects, is reversible without damage. Still further, it is common to fix one element to another by the use of connectors which are separate from the first and second elements. It is desirable to incorporate at least part of a connector in a first or second element. DISCLOSURE OF THE INVENTION 25 In one aspect, this invention relates to a system of fixing one clement to another using remote means. In another aspect, this invention relates to a system which enables the remote fixing and remote release of elements. In still another aspect, this invention relates to a system which can provide information as to the status of the relationship between elements, for example whether they are fixed or not and L ""30 LU "I"II "i1lC]UICILS r"V I ICan 2 fixing or release in a sequential manner between elements. Other aspects will also be disclosed in the following description. It will be appreciated that, in some fields, remote fixing and release is a precursor to self-assembly. 5 The systems of this invention have particular application to the building industry. However, the invention is not limited to this area and has application in many other arts. For the sake of convenience, in many cases the description below will relate to the building industry. Accordingly, in one aspect, this invention provides a connecting means adapted to 10 releasably fix a first element and a second element, the connecting means including a locking means movable by remote activation means between a locked position in which the first element is locked to the second element either by rotation of the locking means or by blocking of a movable member operably associated with the locking means, and an unlocked position in which the first element is released from 15 the second element, characterised in that there is no permanent material connection between the connecting means and the remote activation means and also characterised in that the connecting means includes receiving means for receiving a signal from the remote activation means to fix or release the first and second elements and for activating movement of the locking means to the locked or 20 unlocked position in accordance with the signal. The invention also provides a method of releasably fixing a first element and a second element via a connecting means, the method including the step of applying remote activation means to fix the first element to the second element, the connecting means including a locking means movable by the remote activation 25 means to a locked position in which the first element is fixed to the second element either by rotation of the locking means or by blocking of a movable member operably associated with the locking means, wherein the locking means is movable by the or another remote activation means to an unlocked position in which the first element is released from the second element, there being no permanent 30 material connection between the remote 3 activation means and the connecting means, the connecting means including receiving means for receiving a signal from the remote activation means to fix or release the first and second elements and for activating movement of the locking means to the locked or unlocked position in accordance with the signal. 5 Preferably, the fixing and/or the release can be effected without marking or damaging the first and second elements. In the systems of the invention, there may be more than two elements which are fixed or released. For example, one first element may be fixed to or released from a plurality of second elements; a plurality of first elements may be fixed to or i released from a single second element; or a plurality of first elements may be fixed to or released from a plurality of second elements. Further, where there is a plurality of elements, these need not be identical. A plurality of first elements may differ from one another; a plurality of second elements may differ from one another. 15 The remote fixing or release means may be any suitable means and many of these will be apparent to persons skilled in the various relevant arts. Non-limiting examples of remote fixing and release means are set out below. In the connecting means and method of the invention in one aspect, there is no permanent material connection between the connecting means and the remote 20 activation means. In the specification and claims, a "material connection" means a connection which has physical substance, i.e., substance made of matter, and excludes a connection made through energy. In its simplest forms, the systems of the invention may cause the pushing of two elements together, or the locking of those elements, or the pushing of those two 25 elements apart, or the unlocking of those elements. In this regard, there may be a 15858 4 connecting means which can be regarded as "obedient" to the force or message generated by the remote fixing means. In more sophisticated versions of the systems of the invention, the message can convey instructions (eg. digitally) which will enable the elements to move towards 5 one another or apart from one another, or a connector between them to open or close. In particular, the message may cause movement in any or all of three dimensions. Thus, for example, a first element may be caused to move, relatively to the second element, longitudinally or laterally. A first element may be caused to rotate relatively to a second element. io In yet more sophisticated versions of the systems of the invention, it may be possible not only to transfer messages, but also to receive reports. For example, it may be possible to receive a report as to whether two elements are in a fixed state or in a released state, or whether the connection between them has been damaged or is stressed, for example because of movement as result of an earthquake or 15 because of tampering, such as an attempt to gain access to an electrical duct. Further, encryption may be included in the systems of the invention, to incorporate security. This can be useful, for example, where it is desired to restrict access to elements or to objects or material for which the elements provide a barrier. One example is the fixing of airplane parts, where access to part inspection, removal or 20 replacement is to be restricted to authorised persons. The incorporation of encryption into the systems of the invention can require an appropriately coded activation means in order to permit fixing or release of the elements. These last-mentioned examples of the systems of the invention can be regarded as "intelligent obedient" versions, since not only is there response to a message or 25 force provided by the remote means, but also feedback can be obtained as to state of the fixing or release and access can be restricted in an appropriate manner. Further, this version can prevent access without appropriate authorisation and can provide a record of the time of fixing or release. Thus, for example, unauthorised access to a petrol or gas pump may be prevented and the time of use of the pump 15858 5 by authorised users can be recorded. In one version of the "intelligent obedient" systems of the invention, a report can be obtained as to the location of the fixing or release mechanism. Another advantage which the "intelligent obedient" systems of the invention can 5 have is to prevent unauthorised release after assembly (of the elements) has been completed. The ability of the systems of the invention , in one form, to move one element relative to the other, in any of three dimensions, provides an enormous boost to the problems encountered in the building industry, where wall height, for example, can 10 vary by 50 to 60 millimetres; the present invention, in some aspects, makes it possible to effect required adjustments on site. This permits tolerance, for example, vertically, and gives the capacity to deal with orthogonal movement. It will be appreciated that, in those versions of the systems of the invention which enable release of the elements, the invention provides a ready means for 1s demounting buildings or parts of buildings without the need for demolition and with the ability to preserve building elements for re-use. Further, especially in the "intelligent obedient" form, it is possible to effect fixing or release of the elements in a set sequence. This can be useful, for example, when fixing a large panel to studs. It may be desired to fix the top and bottom corners 20 first to ensure correct alignment and follow by fixing in other areas. In one version of the systems of the invention, the fixing of the four corners of the panel will activate in sequence the fixing at the subsidiary locations. The fixing or release of one element relative to the other may be effected using a connecting means separate from the elements or by using connecting means which 25 are incorporated in the first or second elements, or both. This latter aspect may be regarded as part of "on board technology", which is discussed further, below. As non-limiting examples of connecting means which are separate from the first and second elements, there may be mentioned the following. A fastener having two parts, one being a female part which can be attached to one 15858 6 element during or after manufacture and the other being a male part attached to the second element during or after manufacture can be aligned so that the male part is received within the female part, following which locking of the male part to the female part is effected by remote means. s The remote fixing or release system of the invention has a very wide field of application, indeed. Some of these will now be mentioned. It is to be understood that these are in no way limiting on the scope of the invention. When a power cable connected to a power plug is plugged into a power socket, the plug may be removed whether or not the power is switched on. This can have lo safety ramifications. By using the remote fixing and release system of the invention, it is possible to lock the power plug into the socket when the power is switched on. For example, the power plug may include a locking element and the power socket may include a receiving element. Activation of the "power on" switch can not only cause current to flow through the power cable but, in 15 accordance with the invention, can also fix the locking element to the receiving element, thus preventing withdrawal of the plug from the socket for as long as the "power on" switch is activated. When the "power on" switch is turned off, not only will electricity cease to flow but also the locking element will be released from the receiving element and the power plug can be withdrawn from the socket. 20 In many situations, signs need to be enclosed in a tamper-proof covering. For example, bus timetables which need to be displayed at bus stops are best inserted beneath glass or perspex. Using the remote fixing and release system of the invention, it will be possible to use connectors to connect glass or perspex to a backing board. The connectors are activated by remote activation means, such as 25 by a radio signal. Thus timetables and other information may be changed or updated by authorised personnel using approved equipment. The remote fixing and release system of the invention may also be used to provide security. For example, a computer may be programmed so that it can be released from a cable only after a password has been accepted. For example, the cable may 15858 7 be inserted in the relevant port on the computer to connect power. As soon as the power is connected, the cable plug is fixed within the port and cannot be removed until a series of steps (referred to below) are taken. The fixing of the cable plug to the port may be effected in the following way, as an illustration. The cable plug has 5 (separately from the pins or cavities mating with the port on the computer) a pair of deformable plugs, each of which has a central cylindrical cavity. Each plug fits into a cavity provided near the computer port. As soon as the power is turned on, a pin is caused to enter the cylindrical cavity in the plug and locks the plug into the cavity. The person using the computer logs on and performs the desired tasks. 10 When it is desired to log off, the usual procedures are followed but, before the cable can be disconnected from the computer, it is necessary to enter a password to reverse the locking procedure and release the cable. The computer can then be shut down. Using the system of the invention, cables for computer equipment and mobile 15 telephones, for example, can act as security devices, preventing unauthorised removal of the computer equipment or telephones. The system of the invention can have application in relation to security of other items, for example television receivers, video recorders and sound systems. Using radio frequency, for example, as the remote activation means, such valuable items 20 may be fixed to larger items of furniture or to walls, floors or ceilings. These valuable items may be fixed individually or in a specific order, thus immobilising them. When it is desired to move furniture or any of the valuable items, activation of the radio frequency device will release the locks. Similarly, the remote fixing and release system of the invention can provide 25 security when travelling. As an example, saddle bags can be connected to racks on bicycles and released as desired using remote activation means in accordance with the invention. In the case of valuable equipment such as photographic equipment, the camera can be releasably fastened to a tripod. The lens and lens cap can also be locked onto the 15858 8 camera, all to be removed only after use of correct access codes. It will be readily appreciated that the remote fixing and release system of the present invention can provide security for artwork, without the need for unsightly locks, cables or similar means. Casings on burglar alarms may be made secure, s with access only by authorised means. In the case of automotive accessories and trims, such as spoilers, driving lights, roof racks, air covers, components, radios, cassette decks, CD players, wheel nuts and so on, fixing and release may be effected using the system of the invention, providing convenient fixing in the first place and security thereafter. 10 Locking and release of vehicle doors can be effected remotely, for example by having a connecting element surround the perimeter of the door and being fixable to a complementary element around the door cavity. Access to black box recording devices in aircraft may be restricted as a security means, using the remote fixing and release system of the invention. There are many 15 applications where the remote fixing or release system of the invention can effect fixing in a more efficient and aesthetically acceptable manner than at present. For example, using the system of the invention it is possible to temporarily sound proof a room. For instance, a frame can be applied to the walls and ceilings of the room. Sound proofing panels can then be fixed to those frames using remote activation 20 means. Because no fixing through the panels is required, sound proofing is more complete. When the room is no longer required to be sound proofed, the panels can be released from the frames, using the remote activation means. As another example, the erection of billboards is possible using hidden fixing according to the system of the invention. In this way, it is possible to dispense with 25 the use of messy adhesives and to overcome the problem of misalignment. Items may become multifunctional with the effectiveness of the system of the invention in fixing one element to another until it is desired to release it. For example, it is contemplated that one can provide a multi-purpose boot with a sole which can be removed using remote activation means. A sole suitable for hiking 15858 9 may be attached when that activity is to be undertaken. The same boot may be used for football or similar sporting activities by substitution of a different sole. The boot may be fixed to a ski, for skiing, and so forth. In public toilets there is a problem with maintaining a sufficient supply of paper 5 towels and toilet paper while protecting such consumables against theft and damage. While at present these are usually dispensed from a locked dispenser, it is not possible to protect against unauthorised tampering with the dispenser, since the locking screws or the like need to be accessible. Because the remote fixing and release system of the invention allows the fixing means to be hidden and not 10 accessible without the use of authorised means, this problem can be overcome according to the present invention. A toilet roll or paper dispenser may be locked onto a wall or other mount, with the locking means being hidden under the dispenser and locked or released by the remote activation means. The system of the invention can be used to fasten carpets or rugs onto floors, to 15 substitute for combination dial locks on luggage and other cases, to fix Christmas decorations on buildings and other structures. The system of the invention can be used to prevent access to dangerous items by children, such as to medicine cabinets and through pool fences. Access to coins collected in coin operated machines can be restricted to those having authorisation using the system of the invention. 20 Braces, dentures and false teeth generally may be fixed in position using the system of the invention and released when required. Shop fittings may be constructed in a desired manner and rearranged later using the system of the invention. Fire extinguishers may be locked into position to prevent theft, but releasable by 25 authorised means, or the sounding of an alarm. Fire arms may be stored securely using the system of the invention, preventing unauthorised use. Shipping crates may be locked using the system of the invention so that drugs or other illegal goods cannot be deposited in them.

15858 10 Prosthetic joints may be installed with increased mobility and greater efficiency of joints using the system of the invention. A dog collar may be joined around the neck of a dog using the system of the invention and released when required. The dog collar may include an electronic 6 locating device, together with registration and owner details, all stored electronically. Furniture and building components may be quickly and easily assembled and disassembled. Batteries and access cards on mobile phones may be locked into position to 1o discourage theft, using the system of the invention. Cladding on buildings may be installed quickly, but also easily removed for renovations or repair using the system of the invention. Appliances may have access panels fixed by using the system of the invention, to prevent unauthorised access and enable enforcement of warranties. 15 In the case of tools, interchangeable tool bits may be locked into position using the system of the invention and released when desired, as can accessories for kitchen appliances, for example. Peripherals on computers, such as the mouse, an external disk drive, an external CD ROM, etc. can be secured to a computer by using the system of the invention, 20 with a security code being required to release the peripherals, in a manner similar to that described above in connection with computer cabling. Street furniture may be secured to surrounding structures by using the system of the invention, providing security while in situ and enabling easy removal for maintenance or repair. 25 Buildings, including domestic dwellings, can have all external entrances, windows, power supply and utilities locked off using the system of the invention. The remote activation means may comprise a coded key or radio frequency activation, for example. Activation may occur as a result of a signal from a mobile telephone, as another example.

Locking pin I lies in recess 3 between first element 4 and second element 5. Recess 3 has a narrow end 6 which lies within element 5. When a magnetic force is applied to locking pin 1, it is caused to move within recess 3 as shown in Figure 2, so that leg 8 of locking pin 1 is pushed into narrow io recess 6, in turn expanding wall 9 so that it locks into the recess 10 provided in element 5. Locking pin 1 may be reversed, so that elements 4 and 5 may be released, by the use of magnetic force. Magnetic attraction may be applied for fixing elements 4 and 5 and magnetic repulsion for releasing them, or vice versa. Alternately, the 15 same magnetic force may be applied on opposite sides - for example, on the side near element 4 for fixing and on the side near element 5 for releasing. Turning now to Figure 3, the connecting means 7 illustrated includes a wall plug 11 which can be screw threaded into second element 5 (refer Figure 4) and a cooperating member 12 which includes aerial 13, capacitor 14, switch 15 and 20 encryption logic chip 16. Cooperating member 12 is able to act as a receiver/transmitter and is inserted in first element 4. To fix first element 4 to second element 5, plug 11 inserted in element 5 is aligned with member 12 inserted in element 4. A message is sent, for example, via radio waves, to aerial 13 in member 12 to activate switch 15 which in turn causes plug 25 17 to travel into cavity 18 in the direction of arrow B provided in wall plug 11. Element 4 is thus fixed to element 5. Encryption logic chip 16 may be capable of providing a report as to whether the connection between element 4 and element 5 has been stressed, such as by an earthquake or tremor.

i5 Alternately or in addition, the movement of plug 17 into cavity 18 may transmit a signal to other connecting means which may then be caused to activate. As indicated above, this can be useful in providing a predetermined sequence of fixing, so that a large panel may be fixed at the four corners first, followed by 5 automatic activation of the other fixing points. To release element 4 from element 5, a message can be sent via radio waves to aerial 13 in member 12 to activate switch 15 which will cause plug 17 to travel in the direction of arrow C. Plug 17 will be released from cavity 18 in plug 11 and element 4 can then be separated from element 5. 10 With reference now to Figures 5 and 6, connecting means 19 is designed to be activated by electro magnetic means. Connecting means 19 has a top plate 20 of aluminium and a back fixing plate 21. Base plate 22 is of aluminium. Part 23 is made of acrylic material and surrounds nylon clip 24. Part 25 is also acrylic. Connecting means 19 also includes windings 26, washer 27, pin 28, bobin 29 15 (Teflon - trade mark) and spring 30. As can be seen from Figure 6, connecting means 19 in actual size is small and neat and eminently suitable for connecting a first element to a second element. The canoe clip 31 in Figure 7 is a prior art clip with flexible arms 32 and 33 and a stud 34. As is well known in the art, canoe clip 31 is pushed into the desired cavity. 20 Arms 32 and 33 compress to take up space 35 and once canoe clip 31 has been pushed sufficiently through the cavity so that arms 32 and 33 are no longer constrained, they spring out again to the configuration shown in Figure 7, thus retaining canoe clip 31 in place. In the improvement to canoe clip 31 shown in Figure 8 according to the invention, 25 connecting means 36 shows how, if cavity 37 contains a moveable locking pin 38, activatable by remote means according to the invention, once connecting means 36 has been pushed into position, like the prior art canoe clip 31, locking pin 38 can be moved between arms 32 and 33 to prevent them coming together. Thus, connecting means 36 will fix first and second elements (not shown) together, until 16 locking pin 38 is released by remote activation means. In Figure 9, vehicle door 39 has trim 40 connected to interior of vehicle door 39 by the connecting means of the invention 36, for example, in the region indicated by circle 41. Thus, by using the connecting means of the invention, it is possible to 5 ensure that only factory - approved equipment is used in connection with maintenance of a vehicle. With reference now to Figures 10 and 11, connecting means 42 is based on the known "quarter turn" fastener. Connecting means 42 is shown in position between first element 4 and second element 5. As can be seen from Figures 10 and 11, 10 connecting means 42 does not breach the face surface of element 4, so that element 4 can present a completely blank face for aesthetic or security reasons. Connecting means 42 has a drive magnet 43 and a plunger 44, biased by spring 45. When plunger 44 is caused to press down against spring 45 and rotate, by magnetic or electromagnetic means, channel 46 engages rod 47 to hold connecting means 42 in 1s the locked position, thus connecting elements 4 and 5. Elements 4 and 5 can be released by applying a remote activation means to rotate plunger 44 in the opposition direction, so that rod 47 is disengaged by channel 46. Reference is now made to Figures 12 to 18. These Figures illustrate the application of the invention to the rapid assembly and disassembly of a bolt and nut. Bolt 48 is 20 shown inserted through a panel 49 with a washer 50 inserted between panel 49 and nut 51. As shown in Figure 13, bolt 39 includes channel 52 in which, according to the invention, there is inserted lock pin 53. In the unlocked position, lock pin 53 reposes in head 54 of bolt 58 (refer Figures 14 and 16). In the locked position 25 (refer Figures 13 and 15), lock pin 53 has been caused to travel (by means of a magnet, lock pin 53 being metal) along channel 52, pushing the surrounding shank of bolt 48 outwardly so that external groove 56 engages nut 51. As will be appreciated by one skilled in the art, bolt 48 can be quickly disconnected from nut 51 by using magnetic means to retract lock pin 53 into head 54 of bolt 48.

17 Referring first to Figure 19, connecting means 70 is linear and of indefinite length, as indicated by the top view in Figure20. Connecting means 70 has a base 71 and a channel 72 formed between channel sides 73 and 74. Channel sides 73 and 74 terminate in expanded portions 75 and 76 respectively, for locking into an element 5 when the locking means are activated. Connecting means 70 may have locking teeth 77 along some or all of its length. Locking teeth 77 may be incorporated on one or both of expanded portion 75 and 76. Locking teeth 77 can assist in longitudinal adjustment of one element relatively to another. Connecting means 70 may have a plurality of discrete locking pins 78 (refer i Figures 20 and2l) or a continuous locking strip 79 (refer Figures 22 and23). In either case, the locking pin 78 or the locking strip 79 is activated by remote means to move in channel 72 upwardly to repose between expanded portions 75 and 76, thus preventing them from being deformed inwardly when connecting means 70 is in the locked position. 15 Figure 25 shows an indefinite length of the connecting means 70 with discrete locking pins 78. Figure 26 shows the same connecting means 70 in a flexible form so that it can be shaped around corners or around the perimeter of objects, such as vehicle doors, for example. The connecting means of the invention can be used to fix (and subsequently 20 release) first and second elements being pipes or the like. With reference to Figure27, connecting means 80 is formed as a double-sided version of linear connecting means 70, with a base 81 and channels 82 and 83, being coaxial, each formed between channel sides 84 and 85. As was the case with connecting means 70, each channel side terminates in expanded portions 86 and 87 which are 25 designed to fit into a complementary cavity in pipe walls 88 and 89. Although connecting means 80 may have a continuous locking strip as in the embodiment in Figures 22 and23, illustrated in Figure 27 are discrete locking pins 90. Base 81 may provide an adequate seal between pipes 91 and 92. However, especially in the case where pipes 91 and 92 are intended to carry fluid, it is 18 optional to include seals 93. It will be appreciated that, using the connecting means of the invention, locking pins 90 may be locked between expanded portions 86 and 87 by remote activation means, thus securing pipes 91 and 92 together until it is desired to release them by 5 use of the remote activation means. Figure 28 shows the connecting means 80 following the circumference of pipes 91 and 92. Figure 29 shows an alternate version of a connecting means 94, with a continuous locking strip 95 instead of discrete locking pins 90. 10 A linear connecting means, such as that illustrated in Figures 19 to29, can operate as shown in the detail in Figures 30 and3 1. In Figures 30 and3 1, connecting means 96 has, in this case, a dovetail shaped base 97 and, once again, a channel 98 formed between channel sides 99 and 100. Each of channel sides 99 and 100 terminates in an expanded portion 101 and 102. When it is desired to fix first element 4 to is second element 5 (refer Figure31), connecting means 96 is inserted in a dovetail shaped channel 103 in first element 4 and channel sides 99 and 100 are pressed into cavity 104 in second element 5. Channel sides 99 and 100 are caused to deform inwardly by the constraints of the sides of cavity 104, until expanded portions 101 and 102 reach the expanded part 105 of cavity 104, when channel 20 sides 99 and 100 spring out to their normal position. It is at this stage that locking pin 106 can be activated by remote means, such as magnetic means, to move along channel 98 until it rests between expanded portions 101 and 102. Thus, expanded portions 101 and 102 are trapped within expanded part 105 of cavity 104, since channel sides 99 and 100 can no longer be deformed inwardly to release expanded 25 portions 101 and 102. In this position, shown in Figure30, first element 4 is fixed to second element 5. It will be readily appreciated that reversing the procedure will permit first element 4 to be released from second element 5, without damage or marking to either element. Connecting means 96 is shown inserted in dovetail cavity 103 in element 4, in 19 Figures 30 and 31 and also in Figure32. An alternate arrangement is shown in Figure33, where connecting means 107 has base 108, which is adhered or otherwise fixed to first element 4. Otherwise, connecting means 107 operates in the same way as connecting means 96. 5 In Figure 34 is illustrated a discrete connecting means 109 which has a base 110 (dovetailed in cross-section), a housing 111 for locking pin 112 and plunger 113 and a channel 114 formed between channel sides 115 and 116. Channel sides 115 and 114 terminate in expanded portions 117 and 118. Base 110 can be inserted in dovetail shaped channel 119 in first element 4. When io connecting first element 4 to second element 5, channel sides 115 and 116 are pushed into cavity 120, deforming inwardly to channel 114 and then springing apart again into expanded part 121 of cavity 120. Locking pin 112 can then be activated and pushed by plunger 113 so that it occupies channel 114 between channel sides 115 and 116 and prevents them deforming so as to restrict 15 withdrawal from expanded part 121 of cavity 120. The embodiments in Figures 35 and 36 of connecting means according to the invention are in essence a reversed form of the embodiment of connecting means 109 in Figure34. In Figures 35 and36, connecting means 122 have base 110 and housing 111 together with locking pin 112 and plunger 113 or plunger assembly 20 123. Part 124 of connecting means 122 has shank 125 which is intended to be fixed to second element 5 (not shown). Channel 114 formed by channel sides 115 and 116, together with expanded portions 117 and 118 enter housing 111 during fixing of element 4 to element 5. Locking pin 112 is then activated by remote means - for example, by a radio signal in the case of the embodiment in Figure 35 and by a 25 magnet in the case of the embodiment in Figure36, so that locking pin 112 moves between expanded portions 117 and 118 and locks element 4 to element 5. With reference now to Figures 37 and38, Figure 37 shows a connecting means 126 adapted to be fitted to a first element (wall panel 127) and to be fixed to a second element, stud 128. Connecting means 126 has three sets of ribs, 129, 130 and 131.

20 Ribs 129 permit adjustment of connecting means 126 (and panel 127) to the left and right as shown by arrow 132. Ribs 130 provide for adjustment in the in/out direction as shown by arrow 133. Ribs 130 can lock into extruded locking ribs 134 on stud 128. Ribs 131 provide for up/down adjustment in the direction shown by 5 arrow 135 and can mesh with knurled locking ribs 136 on stud 128. Thus, panel 127 can be adjusted in the desired position before activating means (not shown) fix connecting means 126 to stud 128. In Figure40, foam stud 142 is provided in a length shorter than the vertical height of the wall panel 143 to be mounted. For example, foam stud 142 may be 2 metres 1i long whereas wall panel 143 may be 2.3 metres high. A suitable locking means, activatable remotely, is indicated at 144. Lock 144 could be activated by magnetic means, for example. Stud 142 includes a number of adjustment ribs 145, the profile of which can be seen in the section in Figure4l. In Figure42, the method of the invention is shown in use, in this embodiment 15 connecting a first element - an architrave 146 or a jamb 147, to a second element, panel 148 or 149 respectively. As can be seen from Figure42, architrave 146 and jamb 147 each incorporates a dovetail-shaped channel 150. This is for insertion of a connecting means 151 of the invention, as illustrated in Figure43. Connecting means 151 can operate the same as connecting means 109 in 20 Figure34, for example. It will be readily appreciated by one skilled in the art that cornices and other building elements may be substituted for the architrave 146 or the jamb 147 in Figure42. INDUSTRIAL APPLICABILITY 25 As will be readily appreciated by those skilled in the various arts, the inventions disclosed herein are not limited to the examples set out and have wide applications in many areas. These inventions represent significant advances in the relevant arts.
