Abstract
A securing device for securing a door panel and a complementary door frame housing a latch means in a closed configuration against forced entry. The securing device includes receiving means mounted on the length of the door frame and an engaging means mounted on the length of the door panel, wherein a portion of the engaging means is pivotable between a first configuration and a second configuration. In the second configuration the portion of the pivotable engaging means is nested within the receiving means thereby preventing the door from being forced open. The engaging means is moved between the first and second configurations by a latch engaging means which interconnects the pivotable portion of the engaging means with the latch.
Description




The present invention relates to a securing device, in particular for securing inwardly or outwardly swingable doors or windows in a single or double door assembly. It is common to provide a securing device for securing inwardly or outwardly swingable doors or windows which includes a lock-, bolt-, or latch-mechanism mounted on a door or a window panel, and a keeper or strike plate mounted on a corresponding door or window frame, wherein the door or window is held shut by engagement of the mechanism with the keeper or strike plate. Typically, at least one securing device is disposed, in use, on respective mating edges of the panel and the corresponding frame.




While such securing devices are satisfactory in preventing unforced entry through the door or window, such devices are vulnerable to removal either from the frame or the panel when placed under a concentrated loading.




United Kingdom Patent Number 2233701 describes a door locking arrangement for an inwardly opening hinged door. The door locking arrangement comprises a locking flap which extends substantially the full length of the edge of the door and is hinged to the door frame. It is movable between a position where it traps the edge of the door to prevent its opening and a retracted position where the locking flap is flush with the door frame. The locking flap may be moved between both positions manually or by an electrical drive means.




Although the arrangement provides greater resistance to forced entry on a door, prolonged use of the arrangement will effect wear on the edge of the door panel and an increased likelihood of slippage between the panel and the locking flap if the panel is placed under stress.




It is also interesting to note that as the locking flap travels through its arc of movement to the retracted position, the leading edge of the locking flap is effectively closer to the door panel edge. In order to allow for this effect, there is a requirement for an increased spatial clearance between the door panel and the frame itself The increased clearance has the disadvantage that the door assembly becomes quite noisy—the door rattling within the frame. It will also be appreciated that an increased clearance compensates for warping and lowing occurring in the door and/or frame due to temperature and humidity differentials.




United Kingdom Patent Number 2166795 describes a latching mechanism for a hinged fire door. The latching mechanism comprises a hinged leaf which extends along substantially all of the closing side of the door, and is arranged to engage with an abutting lip of the door frame. The hinged leaf is positioned in a retracted position, to permit the door to be swung open on its hinge, by turning the door handle which is in connective communication with the hinged leaf




The latching mechanism is appropriate for inwardly opening fire doors for which strong steel frames are provided. However, a secure latching arrangement for outwardly opening doors and double doors has not been addressed by the prior art. Furthermore, most conventional domestic inwardly opening doors are provided with wooden door frames and door panels, with a secondary latching mechanism for enhanced security, such as a dead latch, in addition to the primary latching mechanism. The implementation of the abutting lip on the frame described in GB2166795 will require extensive rebating to accommodate the door panel and thus increased labour and expense when fitted to a domestic door frame. The clearance between the door panel and the frame also accommodates the potential for the door to warp, bow or expand under extreme temperatures, for instance, in case of fire. Furthermore, the invention described in GB2166795 does not account for the operation of the secondary latching mechanism found on most conventional domestic doors.




The present invention seeks, among other things, to overcome at least some of the above mentioned disadvantages.




In accordance with one aspect of the present invention there is provided a securing device for securing a panel and a complementary frame housing a latch means in a closed configuration against forced entry, comprising an engaging means configurable in a first configuration in which the panel and the frame are in an unsecured configuration and a second configuration in which the panel and the frame are in a secured configuration, a receiving means for receiving the engaging means in the second configuration, and means for connecting the engaging means to the latch means to enable the engaging means to be moved between the first and second configurations.











The present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:

The angled web member


76


extends between the second arm


725


of the first elongate member


72


and a second surface


743


of the second elongate member


74


. The apex


761


of the angled web member


76


is directed substantially toward the intermediate member


722


of the first elongate member


72


.




The mounting device


70


is provided with a plurality of substantially horizontal gusset members


78


, each gusset member


78


being disposed adjacent to opposing ends of the mounting device


70


. The gusset members


78


are arranged to extend between an enclosed space defined by the angled web member


76


, the first and second elongate members


72


,


74


.




Each gusset member


78


is provided with an aperture


782


. The aperture


782


is arranged to slidably receive a substantially vertically extending pin


79


. The pin


79


is slidable between a first extended position as shown in

FIG. 6

, in which the pin protrudes beyond the opposing ends of the mounting device


70


, and a second retracted position as shown in

FIG. 5

, in which the pin


79


is withdrawn within the mounting device


70


.




An outermost end of each pin


79


is arranged to be received in a substantially vertically aligned recess (not shown) disposed in a substantially horizontal upper or lower surface located above the door panels


100


,


100




a.


It is envisaged that the upper surface could be an overlying door frame, and the lower surface could be a floor or underlying door frame. When the pin


79


is in the first extended position and it is engaged in the recess, the opposing door panel


100




a


is prevented from pivoting about its hinge. When the pin


79


is in the second retracted position and it is disengaged from the recess, the opposing door panel


100




a


is freely pivotable about its hinge.




Each pin


79


is provided with an outwardly extending handle


77


to facilitate movement of the pin


79


between the first extended position and the second retracted position. The handle


77


is arranged to be received in a corresponding cut out portion


75


disposed in the angled web member


76


, at opposing ends of the mounting device


70


as shown in FIG.


6


.




The cut out portion


75


is provided with a first recess


752


disposed proximal to the corresponding gusset portion


78


, and a second recess


754


spaced remote from the same gusset portion


78


. The first and second recesses


752


,


754


are arranged to receive the handle


77


to secure the pin


79


in the first extended position and the second retracted position, respectively.




In use, in order to secure a swingable door panel


100


and a corresponding door frame


200


or door panel


100




a


in a secured closed configuration, as shown in

FIGS. 2

,


4


and


5


, the latch means


300


is operated such that the latch


310


is slid into a first retracted position. The second elongate strip


32


of the engaging means


12


is in communication with the latch


310


by virtue of the engagement of the second member


54


of the latch engaging means


16


in the aperture


312


of the latch


310


and thus the second elongate strip


32


is caused to pivot about the hinge portion


30


to the first position.




In the first position, the door panel


100


may be swung freely into a closed position with the door frame


200


without encountering obstruction to its passage from the receiving means


14


, particularly the flange portion


48


extending outwardly from the door frame


200


.




The latch means


300


is then operated such that the latch


310


is slid into the second extended position. The second elongate strip


32


is caused to pivot about the hinge portion


30


to the second position as shown in

FIGS. 2

,


4


and


5


.




In the second position, the engaging means


12


is received by the receiving means


14


. It will be appreciated that any attempt to open the door panel


100


without operating the latch means


300


to slide the latch


310


to a first retracted position will be prevented because the flange portion


48


provides an obstruction to movement of the door panel when the second elongate strip


32


of the engaging means


12


is in the second position. In such an attempt the flange portion


38


of the second elongate strip


32


is pressed against the flange portion


48


of the receiving means


14


, the flange portion


48


preventing further passage of the door panel


100


to an open unsecured configuration. The door panel


100


is opened by operating the latch means


300


such that the latch


310


is slid into a first retracted position. The second elongate strip


32


of the engaging means


12


is thus pivoted about the hinge portion


30


to the first position, thereby allowing the door panel


100


to swing freely to an open unsecured configuration.




In a conventional prior art arrangement, the door panel and the door frame typically fit closely together and the latch means is generally positioned adjacent a side surface of the door panel such that a dead latch of the latch means engages with a strike plate located on the door frame.




It will be appreciated that in the arrangement of the present invention, the dead-latch of the latch means


300


is not located where it can engage with the strike plate located on the door frame


200


, a substantial gap existing between the strike plate and the dead-latch, as shown in

FIGS. 2

,


4


and


5


.




The dead-latch engaging means


18


is arranged to operate the dead-latch and engage it at the same point and time of closure as would the strike plate in a conventional arrangement.




Furthermore, in the arrangement of the present invention, the door frame


200


is s provided with a primary strike


500


disposed adjacent the flange portion


48


of the receiving means


14


. The primary strike


500


is formed from a resilient plastic material, preferably nylon or polyurethane. The purpose of the primary strike is to protect the second elongate strip


32


from scratches and damage from wear. Additionally, the primary strike


500


provides a surface against which the second elongate strip


32


to interacts upon positioning the door panel


100


and the door frame


200


in a closed configuration, thereby mimicking the sensation of closing and locking a conventional door and frame arrangement. The primary strike


500


also minimises the “rattling” effect of the door panel


100


within the door frame


200


which arises as a result of a spatial clearance therebetween.




It will be appreciated that for double doors or French doors comprising a first door panel and a second corresponding door panel, that instead of providing the receiving means


14


on the door frame


200


, the receiving means


14


may be positioned on the second door panel. The second door panel may be provided with elongate fixtures arranged to accommodate the receiving means


14


. Furthermore, the elongate fixtures may also be arranged to accommodate a protective flashing member positioned over a seam between the first and second door panels to protect the seam from tampering and forced entry.




It will also be appreciated that the receiving means


14


may be mounted on the door panel and the engaging means


12


may be mounted on the door frame.




Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
