SPECIFIC DESCRIPTION OF THE FIGURES

(15) Turning now to FIGS. 1 to 3, there is shown a security device 1. The security device 1 has a first barrier 10 and a second barrier 20 joined by a connecting portion 30.

(16) The first barrier 10 is has a cuboidal shape, comprising a first barrier face 11 and first opposing face 13 joined by a first bridging face 15, and closed by a pair of end faces 17A, 17B. The lower face (not shown) of the cuboidal first barrier 10 is open, and the first barrier is substantially hollow. The first opposing face 13 is provided with a first lower lip 19. The first barrier face 11 and the first opposing face 13 are provided with first slots 12a, 12b, which together define a housing aperture extending through the first barrier 10.

(17) The second barrier 20 is has a cuboidal shape, comprising a second barrier face 21 and second opposing face 23 joined by a second bridging face 25, and closed by a pair of end faces 27A, 27B. The lower face (not shown) of the cuboidal second barrier 10 is open, and the second barrier is substantially hollow. The second opposing face 23 is provided with a second lower lip 29. The second barrier face 21 is provided with a receiving slot 22, which defines a receiving recess or aperture.

(18) The connecting portion 30 is a flat plate extending between lower edges of the first barrier face 11 and the second barrier face 21. The connecting portion 30 is coplanar with the first and second lower lips 19, 29, which thus form a flat base for the security device 1 which can easily be positioned on the floor.

(19) The first barrier 10 is further provided with a handle 50. The handle 50 is broadly C-shaped, and extends from the first opposing face 13. The handle 50 can be affixed by bolts or rivets (not shown) extending through the first opposing face 13, or alternatively the handle 50 can be welded or adhered directly to the surface. The handle 50 indicates the user side (or internal side) of the security device 1, with the second barrier 10 comprising the opposing side (or external side) of the security device 1. It is to be appreciated that the device can be fitted to a door assembly from either side, and thus the terms internal and external are for guidance only.

(20) The security device 1 comprises a locking means comprising a bolt 40, housed within the housing aperture in the first barrier 10. The bolt 40 has a handle portion 41 making it easier for a user to grip. The axial movement of the bolt 40 is limited at a first end by the handle 50, and he opposing end by the inner surface 23a of the second opposing face 23. The bolt 40 is otherwise freely slideable relative to the first barrier 10, through the first slots 12a, 12b and relative to the second barrier 20 through the receiving slot 22, in the direction X shown in FIG. 3.

(21) The bolt 40 is thus moveable between an engaging position and a non-engaging position. In the engaging position, the bolt 40 extends between the first and second barriers 10, 20. Preferably, the leading end 43 of the bolt 40 is received within the substantially hollow second barrier 20. In some alternative embodiments, the second barrier 20 may be solid rather than hollow, in which case the receiving slot 22 may extend into the thickness of the barrier 20 e.g. from the second barrier face 21 toward the second opposing ace 23. In the non-engaging position, the bolt 40 is retracted toward the handle 50, and thus the leading end 43 of the bolt 40 does not extend, or only minimally extends, between the first and second barriers 10, 20.

(22) Turning now to FIGS. 4 and 5, the security device 1 is shown installed on a set of double doors comprising a pair of doors 2, 3. The security device 1 is positioned in the central region 4 of the double doors where the doors 2, 3 meet. Not shown in FIGS. 4 and 5 is the second barrier 20 which is positioned against the opposing faces of the doors 2, 3.

(23) The central region 4 is a small gap between the doors 2, 3 and is commonly fitted with a weather seal or flexible gasket to prevent draughts through the doorway. Since the doors 2, 3 do not completely meet, the central region 4 provides sufficient space for the bolt 40 to pass through the central region and thus extend between the doors 2, 3. Preferably the bolt 40 has a width of no greater than 3 mm, to allow insertion between a pair of doors, where the conventional separation is approximately 3 mm. In some cases it may be necessary to trim the bottom of the leading edge of one or both of the doors 2, 3 (or provide a recess therein) adjacent to the bolt 40 to provide sufficient room for the bolt 40 to move between the doors 2, 3. In such embodiments it may be possible to utilise a bolt with a thickness greater than 3 mm for increased strength.

(24) The lower edge of the doors 2, 3 is received between the first and second barriers 10, 20 above the connecting portion 30. It is thus necessary for the connecting portion 30 to be longer (in the direction of the arrows x or y) than the depth of the doors 2, 3. Preferably the connecting portion 30 is only slightly longer than the depth of the doors 2, 3 in order to ensure a relatively close fit for the security device. Alternatively, a spacer (not shown) can be provided to reduce the distance between the first barrier face 11 and the second barrier face 21.

(25) In FIG. 5 the bolt 40 is partially retracted, and can be slid in the direction of the arrow Y as indicated by the dashed lines, until the leading end 43 is received within the receiving slot in the second barrier (not shown). The bolt 40 is thus in the engaging position. In the engaging position, the bolt 40 prevents the security device 1 from being moved laterally of the doors 2, 3 (i.e. in either direction indicated by arrow Z), since it will contact the end faces of the doors 2, 3. Since the leading end 43 of the bolt 40 is received within the second barrier 20, it is not accessible by any person on the opposing side of the doors 2, 3. Thus a person facing the side of the doors 2, 3 with the second barrier 20 is unable to push the bolt 40 toward the handle 50 and into the non-engaging position.

(26) The installation of the security device 1 will now be described with reference to FIGS. 6 A to D. FIG. 6A shows a pair of doors 2, 3, which are hinged on their outer sides by hinges 4. As a first step, one of the doors, in the example case door 3, is slightly opened by a user 60. The door 3 may be opened further if desired, but all that is required is for the door 3 to be opened sufficiently wide for the second barrier face 20 to pass through the gap between open doors 2, 3. The security device 1 is then moved in the direction D1, for example by sliding the security device 1 along the floor underneath the lower edge of the door 3. As shown in FIG. 6B, the doors 2, 3 can then be closed by moving the open door in the direction D2. It should be appreciated that it does not matter whether the doors 2, 3 are inward or outward opening, or whether they are double hinged. All that is required is that the doors 2, 3 are partially opened.

(27) As shown in FIG. 6C the security device is then slid in the direction D3 until it spans the two doors 2, 3 as shown in FIG. 6D. As this point the locking means e.g. bolt 40 can be moved in the direction D4 to the engaging position between the doors 2, 3. A user 70 on the opposing side of the doors 2, 3 is thus unable to open either door since it is blocked by the security device 1.

(28) Turning now to FIGS. 10 and 11, there is shown a security device 1B. The security device 1B is substantially identical to the security device 1 as described above and as shown in FIGS. 1 to 6, and descriptions of like features held will not be repeated.

(29) The first barrier 10B is substantially the same as first barrier 10, except that the first bridging face 15B is provided with a bolt catch 44. The bolt catch 44 is configured to prevent movement of the locking bolt 40B once the locking bolt 40B has been moved into the engaging position.

(30) The bolt catch 44 comprises a tab 45, which is received within a catch slot 46 in the first bridging face 15B. The tab 45 and catch slot 46 extend along the first barrier 10B parallel with the length of the barrier 10B. The locking bolt 40B is substantially the same as locking bolt 40 described above, except the locking bolt 40B is provided with a notch 42 in its uppermost edge, that is, the edge closest to the first bridging face 15B. The tab 45 is moveable relative to the first bridging face 15B in an upwards direction (as pictured) and/or toward and away from the locking bolt 40B. In use, a user can grip the upper end of the tab 45, and lift the tab 45 upwardly and/or away from the locking bolt 40B.

(31) In FIG. 11, the security device 1B is shown from below. The first barrier 10B is open faced on the surface which would be immediately adjacent the floor in use, thus viewed from underneath the first barrier 10B is approximately U-shaped. The first barrier 10B is provided with a reinforcing portion 47 which extends between and connects to the edges of the first barrier face 11B and the first opposing face 13B located opposite to the first bridging face 15B. Thus, the first barrier face 11B, the first bridging face 15B, the first opposing face 13B and the reinforcing portion define a closed loop with a rectangular or square cross section. The reinforcing portion 47 is preferably welded to the first barrier face 11B and the first opposing face 13B, and provides a strong support preventing the compression of the first barrier 10B.

(32) The reinforcing portion 47 is formed of a plate portion 49, which lies in the plane of the open end face of the first barrier 10B, and a pair of side walls 48A, 48B. The side walls 48A-B extend upwardly from the plate portion 49 toward the first bridging face 15B, thus forming a U-shaped cross-section when viewed in the plane of the bolt 40B. In some embodiments, the edges of the side walls 48A-B can be connected to the first barrier face 11B and the first opposing face 13B, and/or the tops of the side walls 48A-B can be connected to the first bridging face 15B. In other embodiments, the side walls 48A-B extend toward the first bridging face 15B, the first barrier face 10B and the first opposing face 13B, but the side walls 48A-B are not connected thereto. This configuration sacrifices strength for ease of manufacture and alignment. Each of the side walls 48A-B is provided with a slot (not shown) which extends upwardly and is aligned with the catch slot 46 in the first bridging face 15B. Thus, when the tab 45 drops or is biased into the notch 42, it is also received within the slots in the side walls 48A-B. Thus, if the bolt catch 44 is engaged, the bolt 40B is prevented from being retracted by the tab 45 engaging both the catch slot 46 and the slots in the side walls 48A_B. The slots in the side walls 48A_B thus prevent the tab 45 from twisting and thus the bolt catch 44 is more secure.

(33) With the bolt catch 44 disengaged, the locking bolt 40B is able to move freely relative to the first barrier 10B. When the locking bolt 40B is moved into the engaging position, as described above, the notch 42 will be located immediately below the tab 45. The tab then moves into the notch 42 so that it's lowermost (not shown) end is received within the notch 42. The movement of the tab 45 can either be under the influence of gravity, and thus the tab 45 simply drops into position, or the tab 45 can be biased toward the locking bolt 40B, for example by a spring (not shown). Any suitable spring or biasing mechanism can be used, for example: a leaf spring or a compression spring connected between the tab 25 and the first barrier 10B. Thus the bolt catch 44 is immediately engaged whenever the locking bolt 40B is pushed sufficiently inwardly (i.e. toward the second barrier 20B). This can provide a clear indication to a user when the security device 1B is secured, since the tab 45 engaging the notch 42 will provide a click which the user can see, hear and feel.

(34) The bolt catch 44 thus reduced, inhibits or prevents axial movement of the locking bolt 40B. This increases the reliability of the security device 1B, since a person on the opposite side of the door cannot lift the tab 45 and thus cannot push the locking bolt 40B back into the disengaged position. When a user is ready to uninstall the security device 1B, the tab 45 is first lifted to disengage the bolt catch 44 and the locking bolt 40B retracted into the disengaged position by the user pulling the handle portion 41B. The security device 1B can then be moved laterally relative to the door assembly and the doors opened without encumbrance as described previously.

(35) Turning back to FIGS. 7 to 9, there are shown two alternative embodiments of the security device and the method of installation.

(36) In FIGS. 7A and 7B, there is shown a security device 100 in a partially dis-assembled and assembled state respectively. The security device 100 has a first barrier 110, a second barrier 120, and a connecting portion 130. The connecting portion 130 projects perpendicularly from the surface of the second barrier portion 120, toward the first barrier 110. The connecting portion 130 is provided with a locking means 140 consisting of a series of slots 141 on the upper edge of the connecting portion 130, and a cooperating slots 142 in the lower edge of the first barrier 110. The connecting portion 130 is a thin plate, and is configured to extended between the door leafs of a pair of double doors in use.

(37) The width of the slots 141 and the cooperating slot 142 are configured to permit interlocking of the first barrier 110 and the connecting portion 130, as shown in FIG. 7B. When the slots 141 and cooperating slot 142 are engaged with each other, movement of the first barrier relative to the second is restricted. The series of slots 141 permit a degree of adjustability, and thus the offset between the first and second barriers 110, 120 can be adjusted. Thus, the security device 100 can be fitted to doors with various thicknesses of door leaf without requiring modification of the security device 100.

(38) FIGS. 8A and 8B show a further security device 200 which is largely similar to the security device 100. The security device 200 has a first barrier 210, a second barrier 220 and a connecting portion 230. The security device 200 is provided with a locking means 240 consisting of a rail and pin mechanism. The connecting portion 230 is provided with a series of locking holes 241 distributed along the length of the connecting portion 240. The first barrier 210 comprises a slot 242 configured so that the connecting portion 230 can be inserted therethrough. A locking pin 243 is provided and is configured to be insertable into the locking holes 241. To assemble the security device 200, the first barrier 210 is positioned over the connecting portion 230 so that the connecting portion 230 extends through the slot 242, and the locking pin 243 is inserted into the appropriate locking hole 241. The connecting portion 230 and slot 242 thus prevent the first barrier from moving laterally or vertically (as pictured) and the pin 243 thus restricts the first barrier from moving away from the second barrier 220.

(39) Turning now to FIG. 9, the installation of the security devices 100, 200 will be described. As in FIGS. 6A-D, there is shown a double door assembly comprising a pair of doors 2, 3. The doors are hinged on their outer edges, and just the central region where the leading edges abut is shown. The doors 2, 3 are provided with a security device 100, although the method of installation is the same with respect to the security device 200.

(40) In the first step, one of the doors 2, 3 is partially opened to provide a gap 101 by a user 160. The gap 101 in FIG. 9A is exaggerated for clarity, since the leading edge of the door 3 would normally be closer to the door 2. The second barrier 120 is inserted through the gap 101 and positioned on the face of the door opposite to the user 160. The door 3 is positioned so that the leading edge is contacted by the corner formed between the second barrier 120 and the connecting portion 130. A first half 120B of the second barrier 120 thus extends along the surface of the door on one side of the connecting portion 130, and the second half 120B extends away from the door 3 on the opposite side of the connecting portion 130. The user 160 then holds the connecting portion 130 to maintain the security device 100 in position adjacent to the door 3 while the door 3 is closed. When the door is closed, the second half 120B of the second barrier is positioned against the door 2, and the connecting portion 130 extends between the two doors 2, 3.

(41) As shown in FIG. 9B, the user 160 then positions the first barrier 110 over the connecting portion 130 so that the cooperating slot 142 engages one of the slots 141. Preferably, the user selects the available slot 141 closest to the doors 2, 3 to ensure a close fit of the security device 100. When the slot 141 and cooperating slot 142 are engaged with each other, the first and second barriers 110, 120 are coupled together, and cannot be moved relative to each other in either the widthwise direction of the doors 2, 3 nor can they be moved toward or away from each other (i.e. in the direction 105). Should a user on the opposite side of the doors to the user 160 attempt to open either door 2, 3 the movement of the doors 2, 3 will be impeded by the barriers 110, 120 and thus the door is locked closed. To open the doors, it is necessary to first remove the first barrier 110 from the security device 100 by reversing the above steps.

(42) As shown in FIG. 9A, the doors 2, 3 are hinged so that they open outwardly (i.e. away from the user 160). For inwardly opening doors (not shown), the installation process is modified. Firstly, one of the doors is opened to produce a gap, and the second barrier 120 is then positioned against the stationary door. The partly open door is then closed and the first barrier 110 connected to the connecting portion 130.

(43) With respect to the security device 200, the above installation process is identical, except the final step of engaging the slots is replaced with the step of fitting the first barrier 210 over the connecting portion 230 until the first barrier 210 contacts the doors 2, 3 and then inserting the locking pin 243 through one of the exposed locking holes 241.
