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.

of the second elongate member
74
is perpendicularly connected along the length of its edge to an inner surface
721
of an intermediate member
722
of the first elongate member
72
such that the flange portion
75
is directed toward a first arm
723
of the first elongate member
72
. The second elongate member
74
is spaced at a shorter distance from the first arm
723
of the first elongate member
72
than from a second arm
725
of the first elongate member
72
.
An inwardly facing surface
130
a
of the opposing panel
100
a
is provided with a recess
26
a
to house the flange portion
75
. A first surface
742
of the second elongate member
74
disposed adjacent to the flange portion
75
is mounted contiguously on a side surface
110
a
of the opposing door panel
100
a.
A free end
724
of the first arm
723
of the first elongate member
72
is contiguous with an outwardly facing surface
120
a
of the door panel
100
a,
the free end
724
being spaced apart from the side surface
120
a
of the opposing door panel

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.
