Definitions
- This invention relates to locking mechanisms, and in particular to a locking mechanism for an espagnolette assembly and a bar for such a mechanism.
- an espagnolette assembly comprises a drive mechanism mounted in or on a vent which, when activated by a handle, drives rods or bars which extend or retract from the sides of the vent into holes or keeps in the sides of the fixed frame.
- UK patent application GB 22701 10A describes a locking mechanism for a sash whereby a plurality of projections on an elongate carrier attached to the vent frame engage complementary retainers on the sash. The elongated carrier is shifted, to engage or disengage the plurality of projections, by means of turning a handle.
- UK patent application GB 2241531A describes a keep, or keeper, for receiving a locking pin mounted on a movable espagnolette bar such that the associated espagnolette bar is held in a closed position, and a second channel, having a respective open end for receiving the locking pin, inclined from its open end away from the first channel to restrain the espagnolette bar in a partially open position.
- espagnolette locking mechanisms offer many advantages over conventional window locks in terms of security.
- a force, applied perpendicular to the direction of travel of the locking bar will generate a rotational force around the axis of the engagement means. This force may allow sufficient movement in the window/door to facilitate the insertion of a lever or jemmy between sash and frame, thereby increasing the likelihood of the locking mechanism being forced open.
- the present invention aims to improve upon the security of the prior art locking mechanisms for espagnolette assemblies.
- the improved locking mechanism does so by providing a security device for preventing said rotation around the engagement means, thereby preventing movement of the window/door away from the frame.
- the present invention is particularly applicable to an espagnolette assembly, it is envisaged that the locking mechanism herein described could be used in other types of vent lock and, indeed, in other apparatus requiring a secure fastening means.
- a bar for an espagnolette locking mechanism comprising means for engaging a keep, wherein the bar further comprises a security device which follows the engagement means in use into a keep without engaging the keep, wherein the security device prevents rotation about the engagement means during a security attack.
- the engagement means is a pin or spigot designed to engage a keep.
- the pin or spigot is mushroom headed and may be attached to the moveable bar by any means known in the art, including riveting and welding.
- the engagement means may be made from metal, plastics or other suitable material.
- the security device is a pin or spigot.
- the pin or spigot may be any shape suitable for engaging a keep, including mushroom headed.
- the security device may be attached to the moveable bar by any means known in the art; preferably, it is rigidly fixed to the bar.
- the security device may be made from metal, plastics or other suitable material.
- the security device engages the same keep as the engagement means.
- the spacing between the engagement means and the security device is ⁇ 5cm.
- the bar is flat. However, it may be other shapes.
- the engagement means and security device extended substantially perpendicular to the bar, although these angles may be altered if appropriate.
- the engagement means and security device each have substantially the same height.
- an espagnolette assembly comprising at least one bar as herein claimed.
- the espagnolette assembly may further comprise a keep having two engagement slots.
- One engagement slot will allow the window to be engaged in the locked position whilst the other will allow the window to be engaged in a night vent position.
- the engagement slots are defined by flanges to retain the mushroom-headed engagement means within the slot.
- a vent comprising a sash, a fixed frame and an espagnolette assembly as herein described.
- An espagnolette assembly ( Figure 1) comprises two espagnolette rods 2, a drive mechanism 4 and a handle 6 to be mounted on a sash 8.
- Each espagnolette rod 2 comprises a fixed bar 10, further comprising a slot 12, and a moveable bar 14, further comprising a engagement means 16, which is mushroom headed 17, and a security pin 18.
- the fixed bar 10 is secured to the sash 8 and drive mechanism housing 20.
- the moveable bar 14 is positioned in a groove 22 between the sash 8 and fixed bar 10.
- the moveable bar 14 is moveably attached to the fixed bar 10 via the engagement means 16 which extends through the slot 12 in the fixed bar 10 and is flanged to prevent separation of the bars.
- the moveable bar 14 is also attached to gears within the drive mechanism 4.
- the espagnolette assembly ( Figure 1) is activated by the handle 6, which rotates the gears within the drive mechanism 4. These gears extend or retract the moveable bars 14 in opposite directions.
- the bars can engage various keeps on the vent frame by methods known in the art.
- a locking mechanism of the present invention for use in an espagnolette assembly comprises two parts.
- the first part ( Figure 2) comprises an espagnolette rod 2 having a fixed bar 10 and a moveable bar 14.
- the fixed bar 10 further comprises a slot 12.
- the moveable bar 14 further comprises a mushroom headed 17 engagement means 16 and a security pin 18.
- the espagnolette assembly when in use, is mounted on a sash 8.
- the second part ( Figure 3) comprises a universal keep 24 for mounting on a vent frame 26.
- the keep 24 comprises an engagement slot 28 for use in a locking position, a similar engagement slot 30 for use in a night vent position and two slotted fixing positions 32 to allow cam engagement adjustment, with a triangulated third circular final fixing position 34 to ensure keep stability following fixing.
- the engagement slots 28 & 30, are both flanged 31 to retain the mushroom headed 17 engagement means 16.
- the vent In use, with the vent in the closed position, rotation of the handle 6 engages the gears within the drive mechanism 4. These gears extend the moveable bars 14 causing both the engagement means 16 and the security pin 18 to engage the engagement slot 28 of the keep 24 ( Figures 4 and 5).
- the vent may be positioned so as to allow engagement of the engagement means 16 and the security pin 18 with the night vent slot 30. This allows airflow through the vent whilst preventing access.
- An espagnolette assembly of the present invention gives a clear advantage over the prior art by reducing the chance of a window or door being forced open. If a force is applied perpendicular to the direction of travel of the moveable bar 14 and to the axis of the engagement means 16, rotation around the axis of the engagement means 16 will be prevented by the security pin 18. This will subsequently prevent movement of the sash 8 away from the vent frame 26 and decrease the chance of a lever or jemmy being inserted between the sash 8 and vent frame 26.
