Definitions
- the present invention relates to sliding screens incorporating security mesh.
- the present invention relates to a sliding screen closure assembly that provides improved resistance to intruders.
- Sliding security screen assemblies generally incorporate a pair of screens each in the form of a sash having a sheet of security mesh held therein. The sashes generally are slidably retained within separate channels allowing each to slide past the other.
- Such sliding security screens may be susceptible to attack by jemmying, or prizing open, the channel in which the sliding sash is retained.
- a sliding security screen assembly including a frame having an inner channel and an outer channel slidably retaining an inner sash and an outer sash respectively, each of said inner sash and said outer sash framing a security mesh, and said sliding security screen assembly further including at least one latch for maintaining the sashes in a closed condition wherein said outer sash includes an outward projection in the form of an overhanging lip and said outer channel includes an outer wall terminating in a flange wherein said flange is slidably received between the outer sash and the overhanging lip when the outer sash is in the closed condition and wherein said overhanging lip includes a section substantially coplanar with the outer wall of the outer channel.
- the frame of the sliding security screen assembly has an inner channel and an outer channel for slidably retaining the inner sash and the outer sash respectively.
- the frame may conveniently be constructed from extruded sections that may be connected by L-shaped brackets. Such extruded sections may preferably be produced from aluminium. For ease of manufacture and in order to maintain a minimum stock it is preferred that the cross section of such an extrusion be symmetrical about a plane between the inner channel and the outer channel.
- the frame may be produced in any convenient configuration to accommodate sliding inner and outer sashes as may be apparent to those skilled in the art.
- the frame may include attachments for securing the frame to the wall or other construction having an aperture with which the security screen is intended to be secured.
- the frame may be secured to a wall or the like by screws that extend through bores in the base of one or more of the channels.
- Other means of securing the frame to a wall or the like may also be used in the present invention. It is preferred that any securing mechanism which is located within the channel incorporates a finish that is flush with the base of the channel.
- the inner channel and the outer channel on the base of the frame may be provided with rollers, such as balls, or rails on which the respective sashes may ride.
- rollers such as balls, or rails on which the respective sashes may ride.
- the use of rollers may allow for more easy movement of the respective sashes.
- the inner sash and the outer sash both frame a security mesh.
- the inner sash and the outer sash are constructed from sections that are connected by L-shaped brackets.
- Each of the inner sash and the outer sash include an upper and a lower section that configured to be slidably located in the respective channels of the frame and may also include a section that is received in a vertical channel on the frame.
- these sections may conveniently be produced from a single extrusion and thus have the same cross section. These sections may be produced from any suitable materials and it is preferred that they are produced from extruded aluminium.
- the security mesh for use in the present invention may be any convenient security mesh although it is preferred that a woven stainless steel security mesh is used. It is particularly preferred that a woven 316 stainless steel is used in the present invention.
- the sliding security screen "assembly includes at least one latch for maintaining the sashes in a closed condition.
- the latch may be of any convenient type either affixing the sashes relative to each other or affixing the sashes to the frame.
- the outer sash includes an outward projection in the form of an overhanging lip and the outer channel includes an outer wall terminating in a flange wherein the flange is slidably received between the outer sash and the overhanging lip.
- the overhanging lip includes a section that is substantially co-planer with the outer wall of the channel.
- the overhanging lip may be in the form of an L-shaped projection and the flange may be in the form of an opposed L-shaped extension of the outer wall.
- the L- shaped extension of the outer wall extends inwards towards the channel and includes a return that extends into the U-shaped recess formed by the L-shaped projection that forms the overhanging lip and the basic section of the sash.
- the outer sash moves slidably along the outer channel to a closed condition whereby the flange is slidably received between the outer sash and the overhanging lip.
- the overhanging lip and the flange are formed such that the gap therebetween is minimised, particularly such that the tolerances preclude easy penetration of the gap with a jemmy or other prizing means that an intruder may employ to breach the security screen. It is preferred that the overhanging lip be disposed adjacent to the outer wall of the outer channel in a closed condition such that the gab between the overhanging lip and the outer wall is minimised.
- the sliding security screen further includes a releasable lock that provides improved resistance to intruders.
- a sliding security screen assembly including a frame having an inner channel and an outer channel slidably retaining an inner sash and an outer sash respectively, each of said inner sash and said outer sash framing a security mesh, and said sliding security screen assembly further including at least one latch for maintaining the sashes in a closed condition wherein said outer sash includes an outward projection in the form of an overhanging lip and said outer channel includes an outer wall terminating in a flange wherein said flange is slidably received between the outer sash and the overhanging lip when the sash is in a closed condition and wherein said overhanging lip includes a section substantially co-planar with the outer wall of the outer channel wherein said at least one latch assembly and wherein said inner sash includes a latch section substantially perpendicular to the inner channel and a latch hinged
- the inner sash includes the latch section and the outer sash includes the lock section.
- the latch and lock sections are substantially perpendicular to the respective channels of the sashes.
- the latch section includes a latch hingedly connected thereto. It is preferred that the latch includes a bead that may snap fit with a corresponding socket on the latch section.
- the latch may preferably be biased towards a closed condition such as by a spring that acts on a lever arm of the latch. In such a configuration the latch may be moved to an open condition by urging the lever against the bias of the spring.
- Other latching mechanisms may be apparent to ttie skilled addressee without deviating from the spirit and scope of the present invention.
- the lock section includes a detent against which the latch engages in the closed condition.
- the detent may be in the form of a depression in the lock section or alternatively as a raised projection in the lock section.
- the form of the detent is not narrowly critical and a person skilled in the art will be able to comprehend other forms of detent suitable for retaining the respective sashes in position relative to each other whilst the latch in the closed condition.
- the latch section and the lock section of the inner sash and outer sash respectively have opposed projections that intercept in a plane parallel to the plane of either of the sashes.
- the opposed projections are substantially L-shaped and interlock such that the opposed projections intercept in the plane parallel to either one of the sashes and also intercept in a plane normal to that of either one of the sashes.
- the spacing between the opposed projections is preferably such that a potential intruder cannot readily access the latch. It is preferred that an intruder cannot access the latch from the outside of the screen without causing substantial damage to the screen. Thus, by construction of the screen from strong, rigid materials an intruder cannot readily gain access therethrough.
- L-shaped projections are employed and the inner and the outer sash cannot be readily prized apart so as to allow access to the latch due to an interlocking engagement between the respective L-shaped projections.
- the projections may be integrally formed with the locking and latching sections respectively. In a preferred embodiment the projections may be extruded with the locking and latching sections.
