Description

241 5461
ESPAGNOLETTE
This invention relates to an espagnolette locking device for locking a movable leaf in a surrounding fixed frame in a window or door, a striker plate for use with the espagnolette locking device, and an espagnolette locking system comprising an espagnolette locking device and corresponding striker plates.
An espagnolette locking device transmits rotation of a handle into translational movement of a single locking bar extending on both sides of a central drive mechanism.
The locking bar typically has at least one locking pin connected thereto on each side of the central drive mechanism. Rotation of the handle in one direction causes the locking bar to move in a first direction such that the locking pins engage respective striker plates to lock the window or door. Rotation of the handle in the opposite direction withdraws the locking pins from their striker plates, unlocking the window or door.
The striker plates used in espagnolette locking systems typically comprise a recess having an open end and a closed end such that a locking pin may enter the recess from the open end and, in so doing, engage with the striker plate. The striker plate typically has a fixing hole adjacent the closed end of the recess.
Generally, espagnolette locking systems comprise an espagnolette locking device connected to the moveable leaf and a plurality of striker plates connected via their fixing holes to the surrounding fixed frame.
In conventional espagnolette locking systems, a plurality of locking zones are created wherein at each locking zone a locking pin engages with its respective striker plate. The number of the locking zones is typically dependent upon the length of the locking bar to which the locking pins are connected, the length of which is typically dictated by the dimensions of the window or door to which the system is to be installed.
Owing to stringent security regulations, modern locking systems forwindows and doors must meet high standards. There is known in the art a problem in that some conventional espagnolette locking systems fail to meet the required modern standards, such as set by British Standard 7950. To comply with this Standard a locking system must withstand a 3000N load applied in an outward direction to a movable leaf, a 1500N load applied in an unlock direction to the movable leaf, and a 1000N load applied normal to a plane containing the locking bar, this test being repeated twice.
To meet modern security standards the present applicants developed a socalled "bi-directional espagnolette" locking device such as described in GB2398829A, wherein locking pins are arranged in pairs on both sides of a drive mechanism, the locking pins of each pair being displaced towards and away from one another upon rotation of a handle, such that each pair of locking pins engage their respective striker plate in a "pincer" type action to lock a movable leaf into a surrounding fixed frame. Rotation of the handle in the opposite direction correspondingly unlocks the leaf from the frame.
Whilst the bi-directional espagnolette locking system has the advantage of providing a highly secure locking system, capable of meeting the abovementioned BS7950, it has a disadvantage in that it comprises a large number of components when compared with conventional espagnolette locking systems. This results in increased manufacturing and maintenance considerations. The bi-directional espagnolette locking system further has the disadvantage in that the bi-directional espagnolette locking device can cost up to four times as much to manufacture when compared with conventional espagnolette locking devices.
There is therefore a need for an improved espagnolette locking system which overcomes the problems of conventional espagnolette locking systems by being capable of meeting modern security requirements, but that is also significantly easier to manufacture and maintain and cheaper to produce than alternative locking systems.
It is therefore an object of the present invention to provide an espagnolette locking device, a striker plate, and an espagnolette locking system for locking a movable leaf in a surrounding fixed frame in a window or door which overcomes the above problems in
the prior art.
According to a first aspect of the present invention, an espagnolette locking device for a window or door comprises a single locking bar and a drive mechanism for moving the locking bar between a locked position and an unlocked position, the locking bar having locking pins connected thereto arranged at locking zones along the bar, the locking zones being, in use, associated with respective striker plates for receiving the locking pins, wherein a pair of locking pins are disposed at each of at least two of said locking zones, one of said zones being disposed on each side of the drive mechanism, a separation of said zones being greater than the separation of the locking pins of each pair from one another in said zones, the locking pins of each pair being disposed less than approximately 100mm from one another in said zones.
Preferably, the locking pins of each pair are disposed less than approximately 90mm from one another in said zones.
Further preferably, one of the locking pins in each pair of locking pins is an eccentric locking pin which may be adjusted to vary a closure pressure of the movable leaf in the fixed frame. The other of the locking pins in each pair is preferably a concentric locking pin whose primary function is to limit moments generated about the striker plate upon applying a forcing movement to unlock the movable leaf from the fixed frame.
The espagnolette locking device may comprise at least one further locking pin located at at least one further locking zone along the locking bar as desired, depending on the length of the locking bar and the security requirements to be fulfilled.
The drive mechanism preferably includes a drive pinon engaging with a rack connected to, or forming part of the single locking bar. Rotation of the drive pinon causes, in use, movement of the locking bar between the locked and the unlocked positions.
In an alternative preferable embodiment, the drive mechanism includes an arm pivoted at one end and having a pin engaging with an elongate slot of a drive member connected to, or forming part of, the single locking bar. Rotation of the arm causing, in use, movement of the locking bar between the locked and the unlocked positions.
In either of the above described preferred embodiments of the drive mechanism, a rotatable handle is preferably connected to the drive mechanism, rotary movement of the handle, in use, causing movement of the locking bar between the locked and the unlocked positions.
Preferably, the espagnolette locking device further comprises an antijemmy feature for preventing, or at least impeding, jemmying of the moveable from the fixed frame when in the locked position.
The espagnolette locking device of the first aspect of the present invention preferably comprises mushroom headed locking pins for engagement with corresponding striker plates.
In accordance with a second aspect of the present invention, an espagnolette locking system for use in locking a movable leaf into a surrounding fixed frame in a window or door comprises an espagnolette locking device including a single locking bar and a drive mechanism for moving the locking bar between a locked position and an unlocked position, the locking bar having locking pins connected thereto arranged at locking zones along the locking bar, the locking zones being associated with respective striker plates for receiving the locking pins, wherein a pair of locking pins are disposed in each of at least two of said locking zones, one of said zones being disposed on each side of the drive mechanism, a separation of said zones being greater than a separation of the locking pins of each pair from one another in said zones, each pair of locking pins engaging, in use, their respective striker plate such that each locking pin of each said pair engages a respective slot of its respective striker plate upon movement of the locking bar to the locked position.
In accordance with a third aspect of the present invention, a striker plate for use with the espagnolette locking device of the first aspect, or for use in the espagnolette locking system of the second aspect, comprises a first pair of elongate slots, each slot having a closed end and extending towards an open end, the pair of slots being configured for receiving a respective pair of locking pins of the locking device in a first position, one slot of the pair being of substantially the same transverse dimension and extending collinearly in the same direction as the other of the pair.
For co-operation with the espagnolette locking device, the open ends of the slots of the striker plate are preferably disposed less than approximately 100mm from one another, and further preferably less than approximately 90mm from one another.
In a preferred embodiment, the slots have a flanged rim such that they are suitable for capturing respective mushroom headed locking pins.
The striker plates may have a sloping face facing away from the direction of closing the movable leaf in the fixed frame. Such a sloping face may be located adjacent the pair of slots such that neither a base plate of the locking device, over which the locking bar moves, nor any of the locking pins, strike a normal face of the striker plate upon closing, even if the movable leaf moves slightly out of alignment within the fixed frame. The sloping face ensures correct positioning of the locking device with respect to the striker plate without the possibility of causing serious damage to the locking device.
Preferably, a fixing hole is located between the slots. Accordingly, it becomes possible to generate minimal moments about the fixing hole when a forcing movement is applied to open the movable leaf from the fixed frame when in the locked position. Further preferably the open ends of the slots are flared such that the locking pins may more easily enter the slots.
In a preferred embodiment, the striker plate further comprises a second pair of elongate slots being similar to the first pair and being located adjacent thereto for receiving the respective pair of locking pins in a second position. This second position may be a vent position such that the movable leaf may be locked in the surrounding fixed frame whilst allowing the circulation of air.
Particular embodiments in accordance with the present invention will now be described with reference to the accompanying drawings in which: Figure 1 is a perspective view of an espagnolette locking device in accordance with the present invention; Figure 2 is a perspective view of an espagnolette locking system in accordance with the present invention; Figures 3a and 3b are cross-section views of the espagnolette locking system of Figure 2 in the unlocked position; Figures 4a and 4b are crosssection views of the espagnolette locking system of Figure 2 in the locked position; Figure 5 is a perspective view of an exemplary striker plate in accordance with the present invention; and, Figure 6 is a perspective view of an alternative espagnolette locking device in accordance with the present invention.
Turning first to Figure 1 there is there shown a first embodiment of an espagnolette locking device 1 in accordance with the present invention. A second embodiment of the espagnolette locking device 1 is depicted in Figure 2 co-operating with two striker plates 2,2 of the present invention to thereby constitute an espagnolette locking system in accordance with the present invention.
The espagnolette locking device 1 of Figures 1 and 2 comprises a housing 3 for housing a drive mechanism 4. The drive mechanism comprises a 1/4 turn pinion 5 having a square hole 6 for accepting a handle (not shown). The pinion 5 engages a driving element 7 having a rack 8. The pinion 5 is rotatable about an axis, passing through the centre of the square hole 6, in a recess formed in the housing 3. By connecting the handle to the hole 6 and rotating the handle, the pinion 5 rotates causing the driving element 7 to move within the housing 3. The hole 6 may take any form and need not be square but should be suitable for connection to a corresponding handle.
The drive mechanism 4 should not be construed as limited to the exemplary rack and pinion type drive mechanism described above and may instead comprise one of various other types of drive mechanism. For example, the drive mechanism 4 may include an elongate arm having a hole, for accepting a handle, disposed at one end thereof and having a pin disposed at its opposite end, the pin being engageable with an elongate slot formed in a drive element. Again, rotation of the handle causing the driving element to move within the housing of the espagnolette locking device. Various other types of drive mechanism are also envisaged within the scope of the present invention.
A single unitary locking bar 8 is connected to the driving element 7. As shown in the partial cross-section views of Figures 3a, 3b, 4a and 4b of the espagnolette locking system of Figure 2, the driving element 7 comprises a lug for co-operating with a hole formed in the single unitary locking bar 8. The hole extends partially across a width of the single unitary locking bar 8.
It is to be understood that the connection between the driving element 7 and the single unitary locking bar 8 may take many forms and should not be construed as limited to the exemplary connection described above. For example, the drive element may comprise two lugs for co-operating with respective holes formed in the single unitary locking bar. Alternatively, the drive element may be formed integrally with the single unitary locking bar. Various other possibilities for the connection will be apparent to those skilled in the art.
The single unitary locking bar 8 of Figures 1 and 2 has two pairs of locking pins 9,10 connected thereto. Translatory movement of the driving element 7 causes the single unitary locking bar 8 having the two pairs of locking pins 9, 10 connected thereto to move upon rotation of the handle.
The locking pins 9,10 are arranged at locking zones along the single unitary locking bar 8. Each locking zone of the espagnolette locking device 1 is associated with a respective striker plate 2 to constitute the espagnolette locking system of the present invention.
In accordance with the present invention, a pair of locking pins are disposed in each of two locking zones, one locking zone being disposed on each side of the drive mechanism 4.
A separation distance between the two zones is greaterthan a separation distance of the locking pins 9,10 in each pair from one another. Movement of the single unitary locking bar 8 causes all of the locking pins 9,10 to move accordingly, and so these separations remain unchanged by movement of the locking bar 8. The separation distance between the locking pins 9 and 10 of the pair of locking pins 9,10 in each of the two locking zones is less than approximately 1 OOmm and in the embodiments of Figures 1 and 2 is approximately 90mm.
Each pair of locking pins 9, 10 is arranged to engage its respective striker plate 2. Figure 5 shows a perspective view of a second embodiment of a striker plate 2 in accordance with the present invention. The striker plate 2 has a first pair of slots 11 formed therein. The locking pins 9,10 of each pair engage the slots 11 simultaneously.
The first pair of slots 11 are arranged to receive the locking pins 9, 10 for locking a moveable leaf in a fixed frame in a closed position.
The striker plates 2 also have a second pair of slots 12. The second pair of slots 12 are similar to the first pair of slots 1 1 and are located adjacent thereto. The second pair of slots 12 are adapted for receiving the pair of locking pins 9, 10 to lock the moveable leaf in the fixed frame in a partially opened vent position.
Each of the striker plates 2 has a pair of fixing holes 13 for fixing the striker plate 2 to one of the moveable leaf or the fixed frame.
The striker plates 2 of Figures 2 to 4 are functionally similar to the striker plate of Figure 5 and so the following description is equally applicable to both these embodiments of the striker plate of the present invention.
With reference to Figures 3a, 3b, 4a and 4c there are shown cross-section views of the espagnolette locking system of Figure 2. Figures 3a and 3b show the espagnolette locking system in the unlocked position. The locking pins 9, 10 are rivetted through the single unitary locking bar 8 supported on a base plate 14. The striker plates 2 are shown having a cross-section through the first pair of slots 11. Figures 4a and 4b show the espagnolette locking system in the unlocked position.
The slots 11,12 of striker plate 2 each have an open end 15. Upon closing the moveable leaf in the fixed frame, the locking pins 9, 10 lie adjacent respective open ends of the slots 11. The espagnolette locking device of Figure 2 differs from that of Figure 1 in that a fixed pin 16 is also provided. The fixed pin 16 is fixed to the base plate 14 of the espagnolette locking device 1 and not to the single unitary locking bar 8. The slots 11,12 of striker plate 2 each have a closed end 17. Upon closing the moveable leaf in the fixed frame, the fixed pin 16 moves adjacent a closed end 17 of one of the slots 11.
The enlarged section view of Figure 4b shows one pair of locking pins 9, 10 once moved to the locked position. The locking pins 9, 10 lie adjacent the closed end 17 of each of the slots 11. Any forcing action applied to the espagnolette locking system either causes the fixed locking pin 16 to bear against the striker plate 2, the locking pins 9, 10 to abut the closed end 17 of the slots 11, or mushroom heads 18 of the locking pins 9, 10 to bear against flanges 19 of the slots 11, 12, depending on the direction of the forcing action.
The espagnolette locking system of the present invention is sufficiently secure in each forcing direction as required by modern security standards. By providing a pair of locking pins 9,10 in each of the locking zones of the espagnolette locking device 1, rather than a single locking pin as has previously been the convention, the espagnolette locking system of the present invention is significantly more secure than conventional espagnolette locking systems and has many advantages over alternative locking systems.
The espagnolette locking device 1 of the present invention may be manufactured at a unit cost only slightly higher than that of conventional, insecure espagnolette locking devices, and at a much lower unit cost than more complicated, secure alternative locking systems currently available.
The locking pins 10 are concentric locking pins, whereas the locking pins 9 are eccentric locking pins. The eccentric locking pins 9 are adjustable such that a closure pressure of the moveable leaf when locked in the closed position in the fixed frame may be altered. The concentric locking pins 10 are fixed and of a reduced gauge relative to the eccentric locking pins 9.
The elongate slots 11,12 of the striker plate 2 are each formed having substantially the same transverse dimension as one another such that identical striker plates 2 may be used on each side of the drive mechanism 4.
The drive mechanism may be provided with an antijemmy feature, such as described with reference in the present applicant's co-pending GB 0413512. 5 filed 16 June 2004 and entitled "Locking Mechanism", wherein a pin and slot type drive is used in the drive mechanism, similar to that described previously. The slot has a recess such that the pin may engage the recess when a forcing action is applied via the locking bar to lock the drive, thus preventing, or at least impeding, jemmying of the moveable from the fixed frame when in the locked position.
A third embodiment of the espagnolette locking device 1 of the present invention is shown in Figure 6. The third embodiment is substantially identical to that of the first embodiment save that a further eccentric locking pin 9' is provided adjacent the drive mechanism 4, and that the device 1 is substantially longer for fitting to larger windows or doors. The eccentric locking pin 9' is functionally identical to that of the locking pins 9 and is to be used with a conventional striker plate for receiving only a single locking pin.
As will be appreciated by those skilled in the art, various alternatives of the espagnolette locking device and system may be readily contemplated without departing from the scope of the present invention. For example, the eccentric locking pin 9' may be disposed adjacent a further concentric locking pin for forming a third pair of locking pins.
Additional locking pins or pairs of locking pins may be provided as required.
