DOOR LOCKING BAR
FIELD OF THE INVENTION
The present invention provides a door locking bar for use with a door in a building, particularly of the type for use in conjunction with, and 5 being actuated by a second locking mechanism.
BACKGROUND
Securing a door of a building against forced entry by intruders or thieves has always been a problem. To prevent this many types of locks have been developed and are well known. Locks used in residential buildings such 10 as houses and apartment blocks are often lightweight and are often unable to withstand the efforts of a determined individual attempting to break down the door.
To attempt to remedy this problem many individuals have installed dead bolt locks which are stronger than most conventional residential locks and 15 which make it more difficult for a thief or intruder to gain entry through the door. The use of a dead bolt lock is usually only a slight improvement over a conventional lock.
Another method used by individuals to attempt to secure doorways is to use a number of light weight locks spaced along the edge of the 20 door to hold the door more securely. The use of multiple locks like the use of a dead bolt improves the security of the door but can still be overcome by a determined intruder and has the added disadvantage that the individual living inthe building must unlock a number of locks before opening the door which can be inconvenient since it may require the use of a number of different keys.
SUMMARY
According to the present invention there is provided a door locking bar or use with a door extending between a pair of door jambs having an interior face, a side Iying adjacent each of the door jambs, and a dead bolt lock mounted on the door to one side thereof for engaging the adjacent door jamb to lock the door and having a rotatable handle on an interior side of the door being repositionable between an open position with the dead bolt unlocked and a closed position with the dead bolt lock, said locking bar comprising:
a receptacle in the door jamb adjacent the side of the door having 10 the dead bolt;
a bar comprising an elongate member arranged to lie parallel to a plane of an interior face of the door and extending from a first end to a secondend arranged adjacent the door jamb having the receptacle;
bar guiding means for slidably retaining the elongate bar on the 15 door such that the bar may be repositioned between an open position wholly on the door with the second end of the bar retracted from the receptacle, and a closed position with the second end of the bar extended beyond the edge of the door and across a junction between the door and the door jamb such that the second end of the bar is engaged within the receptacle;
a connection member for connecting to the dead bolt handle having a first end fixed to the dead bolt handle and extending outwards from the first end to a second end and being arranged such that rotation of the dead bolt lock between the open position and the closed position causes movement of the connection means between the open position and the closed position;
a linkage member extending between the connection member and the bar and being pivotally connected at a first end to the second end of the connection member and being pivotally connected at a second end to the bar;
and wherein locking the dead bolt causes the dead bolt handle and 5 connection member to rotate from the open position to the closed position causing the second end of the linkage member to move towards the receptacle and thus the second end of the bar to engage within the receptacle thereby further securing the door;
and wherein unlocking the dead bolt causes the dead bolt handle 10 and connection member to rotate from the closed position to the open position causing the second end of the linkage member to move away from the receptacle and thus the second end of the bar to retract from the receptacle thereby unlocking the door.
The door locking bar is designed for use with conventional dead 15 bolt locks which generally have a key lock on the exterior of the door and a rotatable handle on the interior of the door. Actuating the locking mechanism of the dead bolt lock with a key causes rotation of the rotatable handle on the interior of the door. The door locking bar is linked to the handle of the dead bolt such that locking and unlocking the dead bolt handle locks and unlocks 20 door locking bar. The door locking bar thus adds strength and security to thedoor and allows the individual opening the door to use only one key to actuate both the door locking bar and the dead bolt lock.

Figure 1 is a view of the interior face of the door showing the door locking bar in the closed position.
Figure 2 is a view of the interior of the face of the door showing the door locking bar in the open position.
Figure 3 is a top view of the door showing the door locking bar in the closed position.
Figure 4 is a top view of the door showing the door locking bar in the open position.
Figure 5 is side view of the latch plate.
Referring to Figures 1 and 2 the door locking bar is shown generally at 10. The door locking bar 10 is mounted on a door 12 which extends between a pair of door jambs 14 and 16 and has an interior face 18 and sides 20 and 22. The door 12 is hung on the door jamb 14 by hinges 24 15 which pivotally connect the door 12 to the door jamb 14 along its side 20. A
dead bolt lock 26 is mounted on the door at the side 22 of the door and adjacent the door jamb 16. The dead bolt lock 26 has a key slot on the exterior side of the door and a rotatable handle 28 on the interior of the door.The dead bolt lock 26 is arranged such that actuating the locking mechanism of the dead bolt lock 26 to extend the dead bolt 29 by rotating a key in the exterior slot causes rotation of the handle 28 on the interior of the door 12 and such that actuation of the locking mechanism to retract the dead bolt 29 by turning the key in the slot on the exterior of the door 12 causes rotation of the handle 28 on the interior of the door 12 into the open position. The door locking bar 10 is linked to the handle 28 of the dead bolt lock 26 such that rotating the handle 28 of the dead bolt lock 26 causes the door locking bar 10 to be repositioned from an open position to a closed position thereby further securing the door 12.
The door locking bar 10 comprises a receptacle 30 mounted on the door jamb 16, a bar 32 for selectively engaging the receptacle 30, bar guiding means 34 for slidably retaining a bar 32 on the door, a connection member 36 for engaging the dead bolt handle 28 and a linkage member 36 linking the bar 32 and the connection member 36.
Referring to Figures 1 and 5 the receptacle 30 comprises a plate 10 member mounted on the door jamb 16 adjacent the side 22 having the dead bolt 26 and is spaced vertically a distance from the dead bolt 29 along the doorjamb 16. The plate member 30 is fixed to the door jamb 16 and projects out from the door jamb into the interior of the building at a right angle to a planeparallel to the interior face 18 of the door 12. The plate member 30 includes a 15 slot-shaped opening 40 which is sized and arranged to receive a second end ofthe bar 32 therethrough. The slot 40 is usually elongate and arranged to lie substantially vertically.
The bar 32 comprises a elongate plate member which is arranged to lie parallel to the plane of the interior face 18 of the door 12 and extends 20 nearly the width of the door 12 from a first end 42 to a second end 44. The second end 44 is arranged to lie adjacent the door jamb 16 having the receptacle 30 and the first end 42 is arranged to lie adjacent the door jamb 14 having the hinges 24.
Referring to Figures 1, 2, 3 and 4 the bar guiding means comprise 25 a pair of straps which are fixed to the door 12 such that they slidably retain the bar 32 on the door 12. Each strap 34 comprises a plate member which extends across the bar from a first end 46 positioned above the bar 32 to a second end 48 positioned below the bar 32. Each strap 34 is spaced from the interior face 18 of the door 12 and has a hole 50 at each of its respective first and second ends 46 and 48. A spacer 52 having a hole therethrough is arranged to align with each of the holes 50 at the ends 46 and 48 of the strap such that the holes 50 in the strap align with the holes in the spacers 52 to receive a fastener 54 therethrough. The fastener engages the interior face 18 of the door 12 holding the strap in place on the door 12. The bar guide means 10 34 comprise a first strap 34a and a second strap 34b which are aligned with one another and are spaced apart longitudinally along the bar 32. The first strap 34a is positioned on the door 12 adjacent to the side 22 of the door 12 and adjacent the door jamb 16 having a receptacle 30. The first strap 34a is positioned as near the edge of the door as possible to improve the strength of 15 the door locking bar mechanism. The second strap 34a is spaced from the firststrap 34a along the bar 30 towards the side 20 of the door 12. The second strap 34b is positioned as near the side of the door 20 as is practical to improve the strength of the door locking bar mechanism.
The bar 32, the first strap 34a, and the second strap 34b, are 20 aligned with the slot 40 in the receptacle 30 on the door jamb 16. The straps34 are arranged on the door 12 to allow the bar 32 to be repositioned between an open position with the bar 32 wholly on the door and the second end 44 of the bar 32 retracted from the receptacle 30, and a closed position with the second end 44 of the bar 32 extended beyond the edge of the door 12 and across a junction 60 between the door 12 and the door jamb 16 such that the second end 44 of the bar 32 is engaged within the receptacle 30.
The connection member 36 is attached to the dead bolt handle 28 for movement therewith. The connection member 36 extends from a first end 62 attached to the dead bolt handle 28 and extends outwards from the first end 62 to a second end 64. The first end 62 can be attached to the dead bolt handle 28 by any appropriate means. The connection member 36 is arranged on the dead bolt handle 28 such that rotation of the dead bolt lock mechanism between an open position and a closed position will cause rotation of the 10 handle 28 through approximately 90~ and will cause rotation of the second end 64 of the connection member 36 to follow the handle 28 through approximately 90~ from an open position Iying substantially horizontally to a vertical position Iying substantially vertically. The linkage member 38 links the connection member 36 to the bar 32 and extends between the connection 15 member 36 and the bar 32. The linkage member 38 is pivotally connected at a first end 66 to the second end 64 of the connection member 36 and is pivotally connected at its second end 68 to the bar 32. The linkage member 38 is connected to the bar 32 at a position spaced inwards from the second end 44 of the bar 32 and between the first 34a and second 34b strapping members.
Actuating the dead bolt 26 either by turning a key in the key slot on the exterior of the door, or by turning the handle 28 on the interior of the door causes both the dead bolt handle 28, and the connection member 36 to rotate from the open position to the closed position. This causes the second end 66 of the connection member 36 to move from a position spaced 25 horizontally from the handle 28 in an arc to a position spaced vertically from the handle 28 of the dead bolt 26. The movement of the second end 64 of the connection member 36 through this arc causes a corresponding movement of the first end 66 of the linkage member 38 in a horizontal direction towards the receptacle 30. Movement of the first end 66 of the linkage member 38 and 5 therefore of the bar 32 which is fixed to the second end 68 of the linkage member 38. This movement repositions the second end 44 of the bar 32 towards the receptacle 30 and thus moves the second end 44 from the open position to the closed position engaged within the receptacle 30 thereby furthersecuring the door 12.
While one embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
