WO 94/08095 PCT/GB93/01987 PROPERTY SECURITY This invention is concerned with property security and more particularly but not exclusively with the security of property in the form of vehicles whether pushed, towed or prime mover vehicles.

Vehicles such as motor cycles, bicycles and similar wheeled modes of transport are traditionally left unattended by the owners when, for example, entering into a shop, place of work etc., by leaning the vehicles against any convenient wall or space with sufficient width into which to push the motor cycle or bicycle.

To prevent such unauthorised removal the user frequently threads a chain through the wheel and a convenient part of the frame of the cycle. Whilst this may well prevent the cycle from being simply wheeled away it does not prevent the cycle from being bodily removed.

To deal with this problem, experience has indicated that the removal of Lhe cycle or motor cycle by the simple activity of lifting the cycle onto a lorry or into a van is not uncommon.

Whilst this this mode of removing a cycle is easily carried out during the darker winter evenings it can be used at any time where the cycle is not readily viewable.

The problem is compounded by the simple fact that the casual passer-by will not be alarmed on seeing a cycle being stacked onto a lorry, particularly if the person lifting the cycle is wearing some form of uniform or merely the wearing of a peaked cap indicating a possible SUBSTITUTE SHEET -e I WO 94/08095 PCT/GB93/01987 -2- Official who is removing illegally parked cycles.

To counteract this the cycle owner frequently passes the chain through/around a convenient railing/post which may happen to be near by without being concerned as to whether such action is damaging to the railings/posts or whether by so doing the cycle is located in a position dangerous to the public at large, by reason of the cycle occupying a significant part of the width of a road side walkway, thereby forcing pedestrians to step into the road in order to pass the 'parked cycle'.

It is thus an object of the present invention to reduce the ease by which a bicycle or other cycle may be removed.

A further aspect of vehicle security arises for example, in connection with caravans. As is well known a caravan is conventionally towed to a desired site. On reaching the site the person using the caravan releases the caravan from the towing vehicle, arranges the caravan into the desired user position and sets the conventionally provided caraven support units usually located at the corners of the caravan so that the caravan is maintained in a stable position.

Following release of the caravan the user is able to utilise the towing vehicle as he wishes.

Since such use can result in the user travelling away from the parked caravan and as the latter is often readily connectable to any other towing vehicle with the appropriate Lowing connection it follows that the caravan can be readily removed without the owner's consent.

-3- It is thus a further object of the invention to provide means for reducing the ease by which a caravan or other towable vehicle can be removed from a parked location.

Broadly, according to a first aspect of the invention there is provided a device for securing property against undesired removal/displacement, the device including a first unit adapted for countersinking with respect to the ground. or surface at a predetermined location with respect to the property the countersinking being such that the plane of the uppermost surface of the .first unit is positioned below or flush with the adjacent ground or surface; a second unit adapted for connection to said first unit in such manner that when so connected with the first unit the property to be secured against undesired removal/displacement is so secured; and means for enabling locking of the two units one to the other, said locking me'ans including a resiliently loaded part which is movable between a retracted postion during the locking of the units one to the other and a rest postion in which 20 it provides a surface flush or below the adjacent ground.

Preferably, the second unit is adapted for connection to the property to be protected against removal.

In a further arrangement the second unit is arranged to act as a barrier for restraining/preventing the displacement of prperty such as a vehicle from a :predetermined location or position.

In particular, an aspect of the present invention is concerned with property security in which the 'ojuct of the security is to prevent unauthorised entry or, for example, in the case of a vehicle the removal of a vehicle in the absence of the owner.

C RA/, C NT O) I -sl -~sapyC 9 -4- A further aspect of the present invention is the provision of means for positionally supporting/locating vehicles, Conveniently, the first unit includes an upright tube whose upper end is adapted to receive a complementary part of the second unit, and wherein the resiliently movable means is axially displaceable with respect to the upright tube.

In particular, the upper end of the tube is provided with a relatively thick annular plate having a centrally threaded bore which is intended to receive a correspondingly threaded shank forming part of the second unit and' first unit is provided at the region thereof that is cohnectable to the second unit with a key element 15 adapted for engagement with a complementary part of the resiliently moveable means.

In a preferred construction of the post, the upper end thereof is adapted for attachment to a towing arrangement of a vehicle in such manner that the post serves 20 ,additionally as a means for augmenting the conventionally provided arrangments for supporting the caravan in its 'user setting.

In a preferred arrangement the locking arrangeent includes locking balls or the like which are displaceable into their locking position by axial displacement. of a rod between a release position in which the balls are retracted and do not engage with the first unit and a locking position in which the balls are caused to be engaged with both units thereby to prevent relative axial _'VT WO 94/08095 PCT/GB93/01987 movement one from the other.

In a still further arrangement the second unit is arranged Lo serve as a barrier post or the like, the arrangement being such when so used the second unit can serve as i means for blocking a roadway; path; garage entrance; building entrance etc.

In a still further arrangement the second unit can provide as a tethering point for cables or the like serving to lash down an object or part of an object.

For a better understanding of the invention and to show how to carry Lhe same into effect reference will now be made to the accompanying drawings in which:- Figure 1 is a vertical section through a first embodiment of a first unit of a device incorporating the concepts of the invention; Figure 2 is an elevation of a second unit of the assembly of Figure 1; Figure 3 is a vertical section through a second embodiment of a device incorporating the concepts of the the Figure illustrated the first and second units when connected together; Figure 4 is a vertical section through schematic represemLation of a further embodiment of a first unit of a device incorporating the concepts of the invention; and 5 is an elevation of the second unit of the device of Figure 4.

SUBSTITUTE SHEET Il,--a l~sr~e~llRB WO 94/08095 PCT/GB93/01987 6 -6- Referring now Lo Figures 1 and 2 of the drawings from which iL will be noted that the device 1 shown therein includes a base plate 2 which in practice can be square or whatever shape thought convenient. A symmetrically centrally positioned tube 3 is upstanding from the base plate. This tube is secured to the base plate, for example, by welding.

The base plate 2 can be provided with holes (not shown) for receiving reLention bolts or the like (not shown) for the-purpose of enhancing the anchoring of the the base plate.

When mounted the base plate 2 wou-ld be generally horizontal and the Lube vertical In accordance with the proposals of the invention it is intended that the first unit should be countersunk that is the base plate 2 should be so buried and secured to the ground that the uppermost surface of the upper end 4 of the tube 3 is flush or slightly countersunk relative to the surrounding ground surface (indicated by the line US) so that the Lube 3 does not project above the adjacent surroundings thereby to present a hazard over which a person could trip, or which r culd be subjected to the etfects of a load resting thereupon.

It is convenient to note that in a variation of the construction the base plate could be replaced by bars projecting horizonally outwards from the tube.

The upper end 4 of the Lube J is closed by a relatively thick annular plate 5 having a centrally threaded bore u which is intended to receive a correspondingly threaded shank or the second unit or the device which is shown in Figure 2 -s an eyebolt.

SUBSTITUTE SHEET r WO 94/08095 PCT/GB93/01987 7 The shank of this eyebolt 8, which is shown in detail in Figure 2, is intended to be screwed into the threaded bore 6 in the metal tube 3.

The eyebolt 8 is itself intended to be connected Lo or have threaded there through a ch3ain or similar device (not shown) metal loop which in turn is intended to be engaged with a cycle wheel and if possible a part of the cycle frame; or coupled to a cable or the like for lashing down purposes of the or parts of the property to be protected.

It will be appreciated that as so far described the provision of an open threaded bore 6 in the tube 3 which is effectively countersunk below ground level would allow, dirt and debri rapidly to enter the bore and thus ultimately block the bore 6. To prevent such blockage a plastics material insert 9 is arranged within the tube 3.

This insert 9 is axially displaceable lengthwise of the tube 3. The insert 9 has a first part 1U that is intended to be axially slidable with respect to the threaded part 7 of the plate 5 and at the same time be a close sliding fit therein. If thought convenient the insert. 9 could be threaded so as to be engageable with the thread of the bore b.

The lower end 11 of this part 9 terminates in a abutment flange 12 which serves to limit upward travel of the insert part 9 such that the upper end IU thereof cannot project above the upper end 4 of the tube 3.

The insert v has a downwardly directed part 13 which carries a circumscribing laterally extending ring 14 which acts as an abutment ring for the upper end 15 of a SUBSTITUTE SHEET I ~a IIIBLPWb~P WO 94/08095 PCT/GB93/01987 8 compression spring 16 which is intended resiliently to load the insert 9 upwardly to the raised position as is shown in the Figure 1.

The lower end 17 of this spring lo operationally bears against a plug unit Id which serves to seal the lower part of the tube and an aperture 19 provided in the base plate. This latter mentioned aperture 19 is provided to allow assembly of the internal elements the insert 9, the spring Ib, and the plug unit lo. The plug unit has an upstanding pin 20 which maintains the requisite position or the lower end of the spring 16.

To ensure that the threaded shank 7 of the eyebolt d correctly aligns with and engages with the thread u of the plate 3 the shank 7 is provided at its lower end with a key form insert piece 21 having a threaded part 22 engaging with a threaded region 23 of the shank sucl that the insert piece 21 is coaxially positioned with respect to the shank thread. The insert piece 21 terminates in a rectangular cross section key 24.

A complementary insert piece 25 is provided at the upper end 1u of the insert 9, this insert piece 2o having a rectangular cross sectioned recess 20 for receiving the key 24.

As has been mentioned it is intended that the security units will be sunk into the ground at conveniently placed locations; adjacent to a shopping location; in shopping centre car parks at locations set aside for the purposes ot cycle parking; railway station cycle parks and at convenient locations adjacent to public buildings frequented uy persons.

WO 94/08095 PCT/GB93/01987 -9- In use a person who wishes to park his vehicle e.g., cycle engages the eyebolt with the recessed tube plate by inserting the eyebolt key 24 into the key recess 26 of the insert and pushes downwardly so that the insert is moved slightly downwards against the resistance of the compression spring 16. As soon as the shank thread and plate threads are able operationally to cooperate the keybolt 8 is suitably rotated to cause the keybolt shank 7 to be drawn inwards into the tube plate threaded bor'e.

This action progressively displaces the insert 9 downwards. When the eyebolt shank has been sufficiently threaded into the bore 6 the user engages the chain or the like associated with the eyebolt which his cycle in the normal manner. It will be understood that the keybolt rotation threading motion will cause the insert 9 to rotate because of the inter-engagement of the key 24 in the recess 26.

It will be appreciated that once the chain has been engaged with the cycle it is not possible to unscrew the keybolt 8 from the threaded plate 5 mounted to the tube 3 because such action will be prevented by the inability to introduce a sufficient number of twists into the chain or bend a solid loop device. This requirement is facilitated by siting the device at such distance from a wall or the like that it is not possible to man-handle the cycle through a complete turn around the device of the invention.

Referring now to Figure 3 this discloses the application of the concepts of the invention to the provision of temporary posts. In practice, temporary posts, usually vertically arranged, are frequently utilised as a means for preventing access of a vehicle to a previously alotted vehicle parking place; Lo prevent unauthorised access by vehicles through vehicles access roads, to form SUBSTITUTE SHEET LL IIC~s~~ I WO 94/08095 PCT/GB93/01987 10 temporary barriers etc. In addition to such applications the present invention proposes the provision of a temporary post assembly which can be used in conjunction with a caravan or other vehicle as a combined steady for the Lowed vehicle for the prevention of unauthorised removal.

In the embodiment shown in Figure 3 the temporary arrangement is generally identified by the reference 29.

The post arrangement includes a first unit 30 that is intended to be permanently fixed at a location at which it is desired to locate the post and a second unit 32 that forms the actual selectively mountable temporary post itself.

The first part 30 includes a plate 33 provided with bores 34. and an upstanding tube 35 secured by welding to the plate 30. A sleeve 36 having an outwardly directed flange 37 is fitted into upper end of the tube 35, the flange 37 being connected to the upper end of the tube 36.

In use, unit 30 is to be buried countersunk so that the upper surface 38 of the flange 37 is level with the ground surface or other reference surface indicated in the Figure by the line 39.

The upper end of the bore of the sleeve 3b is closable to prevent ingress of dirt and debri by the upper end of a element 4u resiliently loaded by a spring 41 for axial movement lengthwise of the interior of the sleeve J6.

As will be noted from the Figure 3 the lower end of the spring 41 is positionally located by an annular element 4' held in place by a screw 43. The operational length of the spring 4U in association with the axial length of the element 4u and is such that the upper surtace of the SUBSTITUTE

SHEET

PII 1~ WO 94/08095 PCT/GB93/01987 11element can be moved to a position in which it is coplanar with the ground line level 39.

The temporary post unit 32 includes a cylindrical tube 44. An outwardly directed flange 45 provided at one end of a sleeve 46 is secured to the lower end of the tube 32. The outer diameter of the sleeve 46 is such that it is a smooth sliding fit into the interior of the sleeve 3o.

In other words as the sleeve 46 is pushed into the sleeve 36 it pushes downwardly the element 40 against the resilient loading of the spring 41 thereby effectively to allow the lower end sleeve 46 of the temporary support post 32 to be engaged with the part In the case of a post 32 particularly intended for use with a caravan or other towable vehicle having a ball type towing connection (since the latter is well known a description thereof is not thought necessary) a ball element 48 for use with such connection is provided at the upper end of the tube 32.

As so far described it will be appreciated that the post unit 31 can, in the manner dic-ussed, be engaged with the countersunk tube 35 of the unit In accordance with the requirements of the i-vention it is required to be enable the user to be able to lock the post against unauthorised removable from engagement with the part 3U. Thus the unit as so far discussed is provided with a user locking mechanism.

This locking mechamism, in the embodiment shown in Figure 3, operates on the principle of locking two members one Lo the other by means of two or more balls, carried by SUBSTITUTE SHEET L. _I WO 94/08095 PCT/GB93/01987 12 one member and positionally displaceable thereto, being forced into and held in engagement with complementary bores provided in the other of the two members to be locked together.

Thus in the embodiment of Figure 3 locking balls 49 are operationally located in suitably profiled bores provided in the sleeve 46. It is intended that ,the balls, when in their locking position (shown in the Figure 3) should engage into complementary bores/recesses/channel 51 in the sleeve 36. The locking balls 49 are forceably displaceable radially outwards of their carrier sleeve 46 by the tapered end 52 of a locking rod 53 mounted for axial displacement of the tube 32.

As will be seen from the Figure 3 the lower end of the rod 53 is effectively guided by the internal wall of the sleeve 46 whilst the upper end of the rod is guided by the wall of a through bore 54 provided in the ball element 48.

The locking rod is resilently loaded in the upwards direction by a spring 55, acting between a plate 56 engaging with a pin 57 passing through the rod and the top of the sleeve flange The upper end of the locking rod is provided with a manually operated head 58 which is adapted to be retained in the locking position shown in the Figure by the locking of key operated locking arrangements (not shown).

These locking arrangements can be formed by that conventionally used for physically locking the socket part of the ball and socket towing connection one to the other for towing purposes.

WO 9)4/08095 PC/G B93/01987 13 In use, when it is desired to mount the post part 32 to the countersunk part 30 the sleeve 46 is pushed against the top of the element 40 to the level shown in the Figure. On reaching this position the the ball bores and 51 will be aligned. Following this the locking rod is pushed downwards and in so doing the tapered end will push the balls radially outwards to the position shown in the Figure 3. At this position the operating head will be in the position shown. The locking rod is then locked in Lhe down position.

To disconnect the post part 32 from the countersunk part the locking of the operating head is released. It will be found that the spring loading thereof in conjunction with the application of slight movement to the part 32 that the rod 53 will be moved upwardly by the action of its resiliently oading spring. This allows the balls 49 to retract thereby allowing the part 32 to by pulled away front tho part Referring now to Figures 4 and 5, these Figures are concerned with an embodiment of the invention that is particularly intended to provide an upstanding post post which in use blocks or other ways prevents movement of an article located to one side of a post or row of such posts to the other side of the post or row of posts.

The embodiment of the first unit shown in Figure is generally very similar in construction tothat of the first unit of the Figure 3 first unit. For convenience of illustration the first unit shown in Figure 4 has been more schematically represented. It is thought that additional description of Figure 4 is not required since it would essentially be a repetition of that. of the first unit of Figure 3.

SUBSTITUTE SHEET ~a -L 1 R~ re WO 94/08095 PCT/G B93/01987 14 Figure 5 schematically illustrates a second unit construction which inso far as the engagement thereof with the associated first unit is essentially the same as that involved with the second unit of Figure 3. The primary difference between the two second units is that the upper end of the second unit of Figure 5 does not involved the ball like connection for use with caravans but terminates in a push locking head only which' is adapred ro be locked into its downward locking position by means of a key operated lock.3.

Those elements of Figures 4 and 5 corresponding to similar elements of the constructions of the first and second units of Figure 3 have been idenLified by the same reference numerals.
