Description

Locking Device and Method of Installing the same

The present invention relates to a locking device for securing or retaining doors and/or windows in a closed condition or position.

Although the following description refers to locking devices for 'sash jammer’ or door/window stop mechanisms the person skilled in the art will appreciate that the present invention can be used on other latch type retaining members and is not limited to sash jammers or door/window stops.

Often doors and windows, and in particular uPYC doors/windows are fitted with additional locking devices which are mounted on the surface of the door/window or an adjacent surface such as the door/window frame. The devices are mounted on the internal or inside facing surfaces and are operated from the inside. The door/window is prevented from opening by at least part of the device abutting against and/or .0 engaging with a surface adjacent to the one on which it is mounted. As such, the door/window is retained, locked and/or secured in the closed condition. At least part of the device is usually pivotally mounted so that the same is rotated or turned to no longer abut or contact the adjacent surface the door/window can be opened. These types of devices are known as 'sash jammers’ or ‘door/window stops’. A particular problem with these types of devices is that the pivotally mounted part of the device incorporates nylon bushes which can become worn, thereby offering reduced resistance to turning or rotation. Thus the pivotally mounted part can fall due to gravity thereby unintentionally locking the door/window in the closed condition.

In addition, such devices are not operable or openable from the opposite side or outside. Thus, in the event a person is locked out by the device becoming unintentionally locked or if a person on the inside becomes incapacitated and is unable to operate the device after locking the same, it is a time consuming and laborious process to open the door/window. Also the door/window and/or the adjacent frame is inevitably damaged in the process.

It is therefore an aim of the present invention to provide a device that addresses the abovementioned problems.

It is a further aim of the present invention to provide a method of installing a device that addresses the abovementioned problems.

It is a yet further aim to provide a device that can be fitted or retrofitted to existing locking devices to address the abovementioned problems.

In a first aspect of the invention there is provided a locking device suitable for a door, said device including a retaining member mounted on a first surface of said door or on a surface adjacent to the door, said retaining member movable between a first unlocked position in which the retaining member is positioned to permit opening of the door and least a second locked position in which the retaining member prevents opening of the door, a bar member comprising one or more parts at least part of which extends in a direction substantially perpendicular to the first surface and engages with the retaining member when in at least a locked condition wherein the retaining member is selectively moved between the first unlocked and at least a second locked position by disengagement of at least part of the retaining member and/or at least part of the bar member from a further part of the device and pivotal movement of the retaining member relative to the longitudinal axis of the bar member.

The person skilled in the art will understand that the term door includes windows and other such closure structures. Further the pivotal movement is equivalent to rotational movement of the retaining member relative to the longitudinal axis of the bar member or part thereof.

Typically at least part of the retaining member is disengaged from the bar member to selectively move the retaining member between the first unlocked and at least a second locked position.

In one embodiment at least a first part of the bar member is disengaged from a second or further part of the bar member to selectively move the retaining member between the first unlocked and at least a second locked position.

In one embodiment the device includes a collar or plate portion. Typically at least part of the bar member is disengaged from said collar or plate portion to selectively move the retaining member between the first unlocked and at least a second locked position.

As such, the retaining member can be moved between the first unlocked position to at least one locked position from the inside by linear movement of at least part of the retaining member and/or bar member in a direction substantially parallel or coaxial with the bar member and/or further part of the same whilst turning or rotating at least part of said retaining member and/or bar member. Moving at least part of the retaining member and/or bar member in a linear direction parallel or coaxial with the bar member is equivalent to perpendicular movement of at least part of the retaining member and/or bar member relative to the first surface.

In one embodiment of the invention a lock means is located on the second outer or opposite surface of a door or surface adjacent to the same, said lock means engaged with and/or in communication with the retaining member via the bar member. Typically the lock means is attached to the bar member via the collar member.

Typically the lock means is connected to one end of the bar member and the retaining member is attached to the opposite end.

Further typically the lock means enables the door to be opened from the outside by actuation of a lock means to turn the retaining member to the first unlocked position. Thus in this embodiment the lock device enables the door to be opened from the outside by actuation of a lock means to turn the retaining member to the first unlocked position. Also, the retaining member can be moved between the first unlocked position to at least one locked position from the inside by moving or pulling at least part of the retaining member in a linear direction parallel or coaxial with the bar member whilst turning or rotating the same. Moving at least part of the retaining member in a linear direction parallel or coaxial with the bar member is equivalent to perpendicular movement of at least part of the retaining member relative to the first surface and/or movement substantially parallel to an axis extending from the first surface.

In one embodiment the entire retaining member is moved in a perpendicular direction relative to the surface on which the same is mounted before rotational or pivotal movement.

Typically the bar member is substantially linear and/or elongate. Further typically the bar member includes at least one substantially planar surface that extends along at least part of the length of the bar member.

Typically the first and second parts are mated or engaged when in at least the second locked position.

In one embodiment the retaining member includes a recess, aperture or socket configured to receive at least part of the bar member.

Engagement in this manner ensures that the retaining member cannot fall or otherwise be moved by gravity between the first unlocked position and the second locked position as the one or more planar surfaces and/or non-cylindrical shape prevents free rotation or pivoting.

Furthermore, depending on the shape of the bar the retaining means can be selectively positioned in two or more, or a plurality of locked positions.

In one embodiment the bar member extends from the lock means through the door or adjacent surface on which the device is mounted to the retaining member located on the opposite side of the door or surface. Further typically one end of the bar member is received in part of the retaining member adapted to selectively mate with or engage with the same.

In one embodiment the device includes a mounting or base member. Typically the mounting is attached to the first and/or second surface by one or more screws and/or the like. Further typically the mounting or base member includes an aperture into which and/or through which the bar member is received or passes.

In an embodiment without an external lock means, part of the bar member is engaged with a plate member to prevent rotation of the bar member. Typically at least part of the plate member is received within and/or engages with the mounting or base member.

In one embodiment the bar member is at least partially disengaged or removed from the retaining member when moving the same between the first locked and at least second locked positions.

In one embodiment the retaining member includes a stopper means or knob means that selectively engages with the retaining member to prevent movement of the retaining member when engaged.

In one embodiment the stopper means is mounted on said spigot portion. Typically the spigot portion and/or the stopper means include one or more formations selective engagement of which prevent at least the linear or perpendicular movement of the retaining member.

In one embodiment the lock means is a cylinder lock. Typically the bar member engages with and/or is received by at least part of the cylinder lock. Further typically the lock means is a Bristol lock.

Preferably at least the retaining member of the device is mounted on a surface or frame adjacent to the door or window.

In one embodiment the device is formed by fitting at least a bar member to an existing retaining member. Typically at least the bar member is retrofitted to an existing sash jammer and/or the like.

In one embodiment at least part of the retaining member is received in second body portion. Typically the engagement with a second body portion is a latching engagement.

In a second aspect of the invention there is provided a locking device suitable for a door, said device including a retaining member mounted on a first surface of said door or on a surface adjacent to the door, said retaining member movable between a first unlocked position in which the retaining member is positioned to permit opening of the door and least a second locked position in which the retaining member prevents opening of the door, a lock means located on the second outer or opposite surface of a door or surface adjacent to the same, said lock means engaged with and/or in communication with the retaining member via a bar member positioned between the same wherein the retaining member can be selectively moved from a locked position to the open position by actuation of the lock means and the retaining member can be selectively moved between the first unlocked and at least a second locked position from the opposite side of the door by both perpendicular movement of at least part of the retaining member relative to the first surface and rotational or pivotal movement of the retaining member relative to the longitudinal axis of the bar member.

As such, the lock device enables the door to be opened from the outside by actuation of a lock means to turn the retaining member to the first unlocked position. Also, the retaining member can be moved between the first unlocked position to at least one locked position from the inside by moving or pulling at least part of the retaining member in a linear direction parallel or coaxial with the bar member whilst turning or rotating the same. Moving at least part of the bar member in a linear direction parallel or coaxial with the bar member is equivalent to perpendicular movement of at least part of the retaining member relative to the first surface.

In a third aspect of the invention there is provided a method of fitting a locking device to a door or window, said method including the steps of; mounting a retaining member on a first surface and positioning at least part of a bar member between said retaining member and said first surface.

The present invention provides a locking device which is ‘antidrop’ and can also be utilised to provide an outside opening for sash locks, uPVC window and door jammers and/or the like.

Figure 1 shows an embodiment of a locking device or system 2 which is both anti-drop and can be opened from the outside using a key. The system 2 comprises a retaining lever or jammer 4 which is engaged with one end of a linear bar or shaft 6. The bar 6 extends through the surface on which the system is mounted in use (not shown) and is engaged with a lock assembly 8 via a collar 9. The jammer 4 includes a knob 10 which in this example is used to engage and disengage the jammer with the bar 6. In figure 1 the jammer is in the open position or condition which allows the door or window to be opened.

In this example the jammer is moved between positions or conditions by disengaging the jammer 4 from the bar 6 and turning or pivoting the same. Disengagement is achieved by pulling the jammer and/or knob 10 in a direction perpendicular or away from the surface on which it is mounted. Once disengaged the jammer 4 is rotatable. When engaged with the bar 6, the shape of the same prevents rotation, unless first moved in a linear direction.

Figure 2 shows the system mounted on a door frame 16. The jammer 4 includes a base or inside mounting 12 and the lock 8 is positioned on an outside mounting plate 14. Figure 3 shows how such a system looks from the outside when mounted on a door frame surface 16 adjacent to the uPVC door 18. The person skilled in the art will appreciate that the system could equally be mounted on a door surface to prevent opening. Equally the jammer could be received in a body portion in a latching engagement, particularly suitable for 2-way opening windows and doors.

The shape of the bar 6 and/or the part of the jammer that receives or engages with the same determines how many positions in which the jammer can be placed in use. Figure 4 shows two devices 2, 2’ mounted to a door frame 16 both of which are preventing the door 18 from opening although the upper device 2 is at an acute angle in respect of the horizontal whereas the lower device 2’ is substantially horizontal.

In addition, the lower device 2’ does not include a lock assembly and as such cannot be opened from the outside. This system remains ‘anti-drop’ however, as it cannot be pivoted without disengaging the jammer from the bar. Upper device 2 is also anti-drop but can be opened from the outside by actuation of the lock mechanism 8. Importantly, when opened from the outside the jammer 4 does not have to be disengaged from the bar 6 because actuation of the lock with the key turns the barrel and rotates the bar and thus the jammer engaged with the same. When opening from the inside the jammer has to be removed from the bar 6 as rotation of the bar is prevented.

Figure 5 shows an exploded view of the component parts of the system. The bar in this example is hexagonal in shape thus providing at least six positions at which the jammer can be located. The person skilled in the art will appreciate that the bar 6 could be square, hexagonal or any other substantially symmetric polygon. Figure 5 also shows additional parts such as the spring 20 which biases the knob 10 and thus the jammer 4 to the engaged position with the bar 6. Lock plate 22 is utilised when the system does not incorporate an exterior lock. The plate 22 includes an aperture 24 through which the bar 6 passes. The plate 22 is received within formation in the mounting 12, preventing rotation of the bar 6.

Figures 6a-6b show more views detailing the engagement and disengagement of the jammer 4 with the bar 6. Figure 6a shows the jammer 4 in the disengaged position and thus the jammer is free to rotate around the longitudinal axis of the bar 6. Figure 6b shows the engaged condition wherein the socket formation 24 receives the end of the bar 6 and thereby cannot be rotated.

Figure 7 shows a side view of the system whereby the locking plate 22 is engaged with the mounting 12 thereby preventing rotation of the bar 6. As such, this embodiment is intended for fitting without an external or exterior lock. Figure 8 shows the embodiment where the exterior lock 8 is present and one end of the bar 6 is engaged with the lock and the opposite distal end is selectively received in the jammer. This system could also be easily fitter or retrofitted to existing sash jammer locks or stays. The lock in this example is a cam lock.

Figures 9a-9c show how the knob is engaged with the jammer 4 via a spigot 26 that extends from the bar 6 in a locked down position and can be moved to an open position. Figure 9a shows the locked position whereby the socket part 24 of the jammer is engaged with the bar 6. The spring 20 resiliently biases the knob 10 and thereby the jammer 4 to this position. As the knob 10 is pulled away the spring is extended and pulls the jammer body with is thereby removing or disengaging the same. The jammer 4 is thereby free to rotate. The knob 10 is prevented from being pulled too far away from the rest of the jammer body by a pin 28 and washer 30 arrangement located at the end of the spigot 26.

Turning to figure 11a, the embodiment illustrated has a number of structural differences, importantly the jammer 4 or knob 10 does not necessarily have to be pulled away or moved in a linear direction in order to actuate the same from inside. In this embodiment the knob 10 is not present. Retention, particularly of a worn jammer is provided by holding means stopper 32, in this example a sprung ball bearing or detent arrangement which engages with the inside mounting 12 to prevent the jammer lever 4 dropping.

The lock arrangement 8 communicates with the jammer 4 via a split shaft 6a,6b arrangement. The first shaft member 6a is connected to the jammer 4 and the second 6b is connected to the lock 8 via a collar 9. The collar incorporated a screw, in this example a grub screw to secure the shaft member in the same.

The split shaft has substantially square or rectangular pegs or protrusions formed on the adjacent interconnecting faces of the shaft members. The protrusions on one shaft member 6b covers around 50% of the cross sectional surface area of the shaft whilst the other 6a covers around 25%, as shown in figure lib. This arrangement allows the 90 degree range of movement required to open/close the jammer, whilst not having to pivot or rotate the entire shaft. Actuation of the lock and member 6b over 90 degrees, such that the interlocking pegs contact, ensures the jammer can be opened or closed from the outside. The coaxial shaft members 6a,6b are coaxial and mating pin 36 is received by both members and provides a centre of rotation.
