Description

A SLIDING WINDOW ASSEMBLY

FIELD OF INVENTION

The present invention relates to a sliding element assembly, particularly a sliding window assembly.

BACKGROUND TO THE INVENTION

A sliding window assembly comprises a sliding window panel that is configured to translate laterally between a closed position and a fully open position and any position there between. An opening aperture is formed as the sliding window panel slides from the closed position to an open position. The sliding window panel may be configured to slide in a substantially vertical direction or a substantially horizontal position.

A sliding window assembly suitable for providing ventilation in a secure environment typically comprises a sliding window panel and a securely mounted ventilation panel. The ventilation panel is configured to extend across the opening aperture that is formed as the sliding window panel moves to an open position. As a result, the ventilation panel will allow for ventilation (airflow) when the sliding window is moved to an open position but restrict or prevent access via the opening aperture.

By providing a ventilation panel to restrict or prevent access across the opening aperture, the sliding window assembly is suitable for use in a secure environment such as a secure hospital, detention centre or prison etc. However, the ventilation panel also restricts access to the interior region of the assembly and the sliding window panel. Hence, access to the interior region of the assembly and the inner side of the sliding window panel can only be achieved by dismantling the sliding window assembly. Accordingly, any cleaning or maintenance of the interior region and/or sliding window panel is difficult, expensive and time consuming.

SUMMARY OF THE INVENTION

The present invention seeks to overcome, obviate or mitigate the aforesaid disadvantages and provide for an improved sliding window assembly. The present invention seeks to provide a sliding window assembly that may be cleaned and maintained without having to remove any parts or dismantle the assembly. More specifically, the present invention seeks to provide a sliding window assembly where the interior region of the assembly and inner surface of the sliding window may be cleaned and maintained without having to dismantle the assembly.

A first aspect of the invention relates to a sliding window assembly comprising a sliding window panel, a ventilation panel and a support frame, wherein: the sliding window is mounted to translate laterally within the support frame between a closed position and a fully open position, and any position there between; the ventilation panel is mounted to pivot with respect to the support frame between a closed position and a fully open position, and any position there between; whereby when in the closed position, the ventilation panel is configured to extend across an opening aperture that is formed as the sliding window panel translates to an open position so as to allow air flow but restrict access via the opening aperture, and when in the fully open position, the ventilation panel is configured to allow access to an interior region of the assembly and/or the sliding window panel.

By pivotally mounting the ventilation panel as such, an operator may easily gain access to the interior region and/or sliding window panel by simply moving the ventilation panel to the fully open position. Hence, the interior region and/or sliding window panel may be cleaned, maintained, repaired etc. more efficiently, simply and cheaply.

An opening aperture is formed as the sliding window panel moves from a closed position to a fully open position. It will be understood that the size and shape of the opening aperture varies continuously as the sliding element slides within the support frame. The opening aperture is deemed to have a maximum size and shape when the sliding window element is arranged in a fully open position.

The sliding window element is configured such that it can be driven to translate laterally within the support frame in any predetermined direction. For example, the sliding window panel may be configured to translate laterally in a substantially horizontal direction (i.e. from side to side) between a closed position and a fully open position. Alternatively, the sliding window panel may be configured to translate laterally in a substantially vertical direction (i.e. upwardly and downwardly) between a closed position and a fully open position.

The sliding window element is a panel-like structure with a peripheral edge -a lower edge, upper edge, and two side edges. The sliding window panel has an inner side and an outer side.

The sliding window panel comprises a glazing unit. The glazing unit may comprise a single pane or multiple panes of glass. The glazing unit is preferably a double glazed unit. So as to prevent or minimise the breakage of or damage to the glazing unit, the glazing unit may comprise at least one pane of security glass. This is a type of glass that is designed to resist breakage upon impact and includes reinforced or toughened glass as well as laminates or composites of glass and plastics. For example, the pane of security glass may be a laminate of glass and polycarbonate bonded by a polyurethane resin.

An example of security glass is referred to in the trade as "anti-bandit attack" glass.

For the purposes of this document the term "sliding window panel" is intended to be any type of sliding panel comprising one or more glazing unit. For example, the sliding window panel may be a sliding window element or a sliding door panel comprising a window.

The sliding window panel may comprise a secondary peripheral frame. For example, the sliding element may be a sliding window panel comprise a secondary peripheral frame extending substantially around a glazing unit. The support frame is configured to receive and support at least a part of the peripheral edge of the sliding window panel.

The support frame is preferably a peripheral frame that extends substantially around the peripheral edge of the sliding window panel. This type of frame may have a substantially rectangular shaped structure comprising a lower wall, upper wall and sidewalls. The support frame has an inner side and an outer side. The sliding window panel is preferably slidably mounted within a rebate or channel of the support frame.

The support frame is preferably manufactured from a material that is designed to resist damage or breakage upon impact, e.g. steel or aluminium.

An inner side of the assembly is defined by the inner side of the sliding window panel and inner side of the support frame. An outer side of the assembly is defined by the outer side of the sliding window panel and outer side of the support frame.

So as to aid the lateral translation of the sliding window panel within the support frame, the sliding window panel may be slidably mounted on a sliding track or guide rail. The sliding window panel may be mounted on a sliding track via at least one rollable member (e.g. wheel). If the sliding window panel is required to slide in a substantially horizontal direction then the sliding track is arranged to extend along at least a part of the lower wall and/or upper wall of the support frame. Depending on the configuration and type of sliding track, the sliding track may be arranged within a rebate of the lower wall and/or rebate of the upper wall. If the sliding window panel is required to slide in a substantially vertical direction then the sliding track is arranged tn tn1 Innn at least a part of one or both of the sidewalls of the support frame. The sliding track may be arranged in a rebate of one or both of the sidewalls.

The ventilation panel is a panel-like structure comprising a ventilating region and preferably a secondary peripheral frame. The ventilation panel comprises a peripheral edge -a lower edge, upper edge and two side edges. The ventilation panel has an inner side and an outer side.

The ventilating region of the ventilation panel may comprise a perforated element, a mesh or a grill comprising a plurality of apertures configured to allow for air flow. The perforations or apertures are configured to allow airflow when the sliding window panel is open but restrict or inhibit the passage of contraband or unsuitable items. Thus, contraband etc may not be transferred through the window, even when the sliding window panel is arranged in an open position.

The ventilation panel is preferably manufactured from a material that is designed to resist damage or breakage upon impact, e.g. steel or aluminium.

The ventilation panel is mounted in the support frame such that when it is in the closed position it is configured to extend across at least the opening aperture formed when the sliding window panel moves to an open position.

Critically, the ventilation panel may be configured to extend across at least the maximum opening aperture formed when the sliding window panel is in a fully open position.

When arranged in the closed position, the ventilation panel preferably forms a sealing engagement with the support frame so as to restrict or prevent any access via the opening aperture. The ventilation panel is also arranged in sealing engagement with the support frame so as to prevent, minimise or restrict the attachment of a ligature.

So as to extend across at least the opening aperture, the ventilation panel is be configured such that it extend substantially parallel with rsrrt tn th sliding window panel when both the ventilation panel and sliding window panel are arranged in their respective closed position. The ventilation panel is mounted in the support frame in a parallel plane with respect to the sliding window panel. The ventilation panel may be configured with respect to the inner side or the outer side of the sliding window panel. The ventilation panel is configured so as to restrict or prevent access to the inner region of the assembly (including the interior of the support frame) and/or the sliding window panel.

The ventilation panel may be pivotally mounted so as to pivot about a substantially horizontal axis. In this case, the ventilation panel is preferably pivotally coupled to the upper wall of the support frame so as to pivot about an axis that is parallel to the upper wall of the support frame. As a result, the ventilation panel is pivoted in an upwardly, anti-clockwise direction to move the ventilation panel to an open position and in a downwardly, clockwise direction to move the ventilation towards the closed position. Alternatively, the ventilation panel may be pivotally mounted so as to pivot about a substantially vertical axis. In this case, the ventilation panel may be pivotally coupled to a side wall of the support frame so as to pivot about an axis that is parallel to the side wall of the support frame.

It is to be understood that the sliding window assembly may comprise any type of protective panel member configured to restrict access across an opening aperture. The protective panel member need not necessarily comprise a ventilating region.

The assembly comprises pivoting means to pivotally couple the ventilation panel and support frame and thereby allow for the pivoting of the ventilation panel between a closed position and an open position and any position there between. The pivoting means may include any suitable type of pivoting means.

For example, the pivoting means may comprise one or more hinges such as a slide stay friction hinge, a Butt hinge or a Continuous hinge.

The pivoting means may be manually operable pivoting means or electronically controlled pivoting means.

The pivoting means are preferably configured and/or located so as to restrict, limit or prevent the attachment of a ligature.

The assembly may comprise restricting means so as to restrict the pivoting movement of the ventilation panel. For example, the assembly may comprise restricting means to define the closed position of the ventilation panel. In this case, the restricting means are configured to abut the ventilation panel when the ventilating panel is arranged substantially flush and/or in sealing engagement with the support frame.

The interior region is the inner region of the assembly as defined by the ventilation panel and the sliding window panel.

The assembly may comprise a locking means to lock the ventilation panel in the closed position. The lock means may comprise a key operated lock. The lock is preferably a tamper-proof lock. The locking means are provided so that only an authorised operator may open and close the ventilation panel.

The sliding window panel may be actuated by manually pushing or pulling the sliding element in a given direction such that it slides between the close position and the fully open position.

So as to reduce the effort required to push or pull a sliding window panel, the assembly may comprise a driving mechanism to actuate the sliding window panel. The driving mechanism may be a manually operable or electronically controlled drive mechanism.

The manually operable drive mechanism may include a manually operable handle coupled to a sliding element via actuating means whereby the handle must be rotated/moved in one direction to activate the actuating means and thereby move the sliding element towards a first position and rnttr1Imn,r1 in the opposite direction to activate the actuating means and thereby move the sliding element towards a second position. The actuating means may comprise gear means to drive and essentially control the motion of the sliding window panel. The drive means comprises a rack and pinion system. With this type of drive mechanism the direction of the sliding motion is dependent on the direction of rotation/movement of the handle -the handle must be rotated/moved in different directions in order to move the sliding element in different directions. For example, a rotatable handle must be rotated in both a clockwise and anti-clockwise direction to move the sliding window panel in different directions. The extent of the sliding motion is dependent on the circumference of the pinion gear wheel and the length of the associated rack.

The assembly may alternatively comprise a reciprocating drive mechanism for actuating a sliding window panel comprising a rotatable handle and an actuating means whereby the rotatable handle is configured to drive the actuating means and the actuating means is configured to reciprocately drive a sliding window panel between a first position and a second position, and any position there between, as the handle is rotated.

The reciprocating drive mechanism is provided to control the movement of the sliding window panel such that it is able to translate laterally within the support frame in a reciprocal fashion between a first position and a second position, and any position there between, as the handle is rotated in the same direction.

By configuring the drive mechanism so as to reciprocately drive the sliding window panel the handle need only be rotated in one direction in order to move the sliding window panel between the first position and second position and any position there between. Thus, the risk of damaging or breaking the drive mechanism by over rotating the handle is rninimised or avoided.

This particular type of reciprocating drive mechanism is described in UK patent application no 09031964. The teaching relating to the reciprocating drive mechanism from the UK application is deemed to be incorporated in this document.

The drive mechanism may be configured to reciprocately drive a sliding window panel in a substantially vertical direction. Alternatively, the drive mechanism may be configured to reciprocately drive a sliding window panel in a substantially horizontal direction.

The handle may be a manually rotatable handle. Alternatively, the handle may be an electronically controlled rotatable handle and the drive mechanism may comprise an electronic control means to remotely control the rotation of the handle.

Preferably the handle has a tamper-proof configuration so as to prevent, minimise or restrict the failure of the handle caused by deliberate or accidental damage. The handle may further or optionally have an anti-ligature configuration so as to prevent, minimise or restrict the attachment of a ligature.

The drive mechanism may further comprise a rotatable drive shaft coupled between the handle and the actuating means, whereby the handle drives the actuating means via the drive shaft.

The actuating means preferably comprises a gear system and a reciprocating arm whereby the reciprocating arm is configured to move in a reciprocating fashion as it is driven by the gear system.

So as to achieve a reciprocating effect, the reciprocating arm may be configured to continuously extend and contract as the handle is rotated.

Preferably, the reciprocating arm comprises a plurality of interlinked arms that pivot relative to one another as the handle is rotated so as to extend and contract the reciprocating arm.

The drive mechanism may further comprise a coupling means to couple the reciprocating arm and a sliding element.

The drive mechanism may optionally comprise a body portion to support other component parts of the drive mechanism. The drive mechanism mv rnmnris a guide means to guide the reciprocating arm as it moves in a reciprocating fashion.

The drive mechanism may comprise a housing means to restrict access to the drive mechanism, particularly the actuating means.

The drive mechanism is preferably configured as part of the assembly such that the handle of the drive mechanism is arranged externally to the support frame and sliding window panel on a predetermined side of the assembly. The handle is also preferably configured such that it is only visible and thereby accessible on a predetermined side of the assembly. For example, the drive mechanism may be configured such that a manually rotatable handle is arranged on the inner side of the assembly. Thus, when an assembly is mounted in a wall of a room space, the rotatable handle is only visible and operable by a user within the room.

The arrangement of the rotatable handle on the inner side of the assembly is dependent on the configuration of the actuating means. For example, the rotatable handle may be arranged in a lower right-hand corner region of the inner side of the support frame in order to drive the actuating means such that the reciprocating arm extends or moves forwardly to a first reciprocating arm position in order to open the sliding window panel and contracts or moves backwardly to a second reciprocating arm position in order to close the sliding element. Alternatively, the rotatable handle may be arranged in a different region of the inner side of the support frame (e.g. a lower central region) in order to drive the actuating means such that the reciprocating arm contracts or moves backwardly to a second reciprocating arm position in order to open the sliding element and extends or moves forwardly to a first reciprocating arm position in order to close the sliding window panel.

The assembly may comprise a secondary panel mounted in the support frame.

The secondary panel has a panel-like structure with a peripheral edge -a lower edge, upper edge and two side edges. The secondary panel may have an inner side and an outer side.

The secondary panel may comprise a secondary peripheral frame.

The secondary panel may be a secondary window panel comprising a glazing unit. The secondary window panel is provided to allow natural light to fall into the room space so as to aid an occupant's comfort.

The secondary panel is mounted in the support frame such that it is in a parallel plane to the sliding window panel and substantially adjacent the ventilation panel in the same plane. Hence, the sliding window panel slides relative to the secondary panel and ventilation panel.

The secondary panel may be securely mounted in the support frame.

Alternatively, the secondary panel may be pivotally mounted in the support frame such that it is able to pivot between a closed position and a fully open position, and any position there between. The secondary panel may be pivotally mounted so to help provide further access to the inner region of the assembly and/or the sliding window panel.

As with the ventilation panel, the secondary panel may be pivotally mounted such that it pivots about a substantially horizontal axis. The secondary panel may be pivotally coupled to an upper wall of the support frame so that it may pivot about an axis that is substantially parallel to the upper wall of the support frame. Alternatively, the secondary panel may be pivotally mounted such that it pivots about a substantially vertical axis. The secondary panel may be pivotally coupled to a side wall of the support frame so that it may pivot about an axis that is substantially parallel to the side wall of the support frame.

According to a second aspect of the invention there is provided a sliding window assembly comprising a sliding window panel, a ventilation panel a secondary panel and a support frame wherein: the sliding window panel is slidably mounted in the support frame such that it can translate laterally within the support frame relative to the ventilation panel and the secondary panel between a first position and second position, and any position there between; the ventilation panel is securely mounted in the support frame and configured such that it extends across an opening aperture that is formed as the sliding window is translated to an open position so as to allow air flow but restrict access via the opening aperture, and the secondary panel is pivotally mounted in the support frame such that it can pivot between a closed position and a fully open position and any position there between, whereby in the fully open position the secondary panel is configured to allow access to an interior region of the assembly and/or the sliding window panel.

By pivotally mounting the secondary panel as such, an operator may easily gain access to the interior region and/or sliding window panel by simply moving the secondary panel to the fully open position. Hence, the interior region and/or sliding window panel may be cleaned, maintained, repaired etc. more efficiently, simply and cheaply.

The secondary panel may be a window panel.

The sliding window assembly preferably comprises pivoting means to pivotally couple the secondary panel to the support frame. The pivoting means may include any conventional pivoting means. For example, the pivoting means may comprise one or more hinges such as a slide stay friction hinge, a Butt hinge or a Continuous hinge.

The sliding window assembly may comprise a drive mechanism to actuate the lateral translation of the sliding window panel. The drive mechanism may be a manually operable or electronically controlled drive mechanism. The drive mechanism may be a reciprocal drive mechanism.

It should be understood that this invention is applicable to any type of sliding element assembly. For example, this invention may relate to a sliding door assembly.

A further aspect of the invention relates to a sliding element comprising a sliding element, a secondary element and a support frame wherein: the sliding element is mounted to translate laterally within the support frame, relative to the secondary panel, between a closed position and a fully open position, and any position there between; the secondary panel is mounted within the support frame in stepped relationship to the sliding element and to pivot with respect to the support frame between a closed position and a fully open position, and any position there between; whereby in the fully open position, the secondary panel is configured to allow access to an interior region of the assembly and/or the sliding element.

BRIEF DESCRIPTION OF DRAWINGS

For a better understanding of the invention and to show how it may be carried into effect reference shall now be made, by way of example only, to the accompanying drawings in which: Figure 13 depicts a view of the inner side of an embodiment of a security window assembly; Figure 14 depicts a view of the outer side of the security window assembly of Figure 13; Figure 15 depicts a plan view across section A-A of the security window assembly of Figure 13; Figure 16 depicts a perspective view of the inner side of the security window assembly of Figure 13.

DETAILED DESCRIPTION OF THE INVENTION

Figures 13 to 16 depict an embodiment of a particular type of sliding window assembly. Figures 13 to 16 depict an embodiment of a security window assembly. The security window assembly is suitable for providing ventilation in a secure environment (e.g. room space) where the safe detention of an occupant is paramount. For example, the security window assembly is suitable for use in a secure hospital, detention centre or prison etc. The security window assembly may be mounted in a wall defining a room space. An inner side of the security window assembly is preferably configured to face inwardly or internally towards the room space. An outer side of the security window assembly is preferably configured to face outwardly or externally in the opposite direction away from the room space.

In the embodiment depicted in Figured 13 to 16, the security window assembly (100) comprises a fixed window panel (200), a sliding window panel (300), a ventilation panel (400), a support frame (500) and a drive mechanism (1) according to the first aspect of the invention. See the view of the inner side of the assembly as depicted in Figure 13 and the view of the outer side of the assembly as depicted in Figure 14.

The fixed window panel (200) is a type of fixed element. The fixed window panel (200) is provided to allow natural light fall into the room space so as to aid an occupant's comfort. The fixed window panel also allows for the observation of an occupant retained in a room space. A security window assembly may comprise one or more fixed window panels.

The fixed window panel may comprise a single pane or multiple panes of glass. The fixed window panel is preferably a sealed double-glazed unit.

So as to prevent or minimise the breakage of or damage to the fixed window panel, the fixed window panel preferably comprises at least one pane of security glass.

If the fixed window panel comprises a multiple pane glazed unit then one or more of the panes of the glazed unit may comprise a pane of security glass.

Preferably a pane of security glass is mounted on the inner side of the security window assembly so as to minimise any damage caused by an occupant.

Alternatively, the fixed window panel may further comprise a pane of security glass mounted (within the support frame) separately to the glazed unit on the inner side of the security window assembly and/or a pane of security glass mounted (within the support frame) separately to the glazed unit on the outer side of the security window assembly.

If the fixed window panel comprises a single pane of glass then the pane of glass is preferably security glass.

The fixed window panel (200) is securely mounted in the support frame (500).

The fixed window panel is preferably securely mounted in a first portion of the support frame. The first portion of the frame preferably has a first internal rebate to permit the fixed panel unit to be securely received in the frame during assembly.

The fixed window panel has an inner side (2001N), an outer side (2000UT) and a peripheral edge. The fixed window panel is securely mounted in the support frame such that when the assembly is mounted in a wall defining a room space the inner side of the fixed window panel faces inwardly towards an internal room space and the outer side of the fixed window panel faces outwardly away from the room space.

The sliding window panel (300) is a type of sliding element. The sliding element assembly may be configured such that the sliding window panel (300) is able to translate laterally in a horizontal direction between a first position and a second position and to any position there between -Of course, a security window assembly may be alternatively configured to allow for lateral translation in a substantially vertical direction.

The security window assembly may comprise one or more sliding window panels.

The sliding window panel may comprise a single pane or multiple panes of glass securely mounted in a secondary peripheral frame (310). The sliding window panel is preferably a sealed double-glazed unit surrounded by a secondary peripheral frame.

The sliding window panel preferably comprises at least one pane of security glass. If the sliding window panel comprises a multiple pane glazed unit then the glazed unit may comprise one or more panes of security glass.

Alternatively, the sliding window panel may further comprise a pane of security glass mounted (within the support frame) separately to the glazed unit on the inner side of the security window assembly and/or a pane of security glass mounted (within the support frame) separately to the glazed unit on the outer side of the assembly.

If the sliding window panel comprises a single pane of glass then the pane of glass is preferably security glass.

The sliding window panel (300) is slidably mounted in the support frame (500), such that it can translate laterally (i.e. slide) between a first, closed position and a second, fully open position and any position there between. The sliding window panel is preferably slidably mounted in second portion of the support frame. The second portion of the frame preferably has a second internal rebate to permit the sliding window panel to be received in the frame during assembly.

The sliding window panel is preferably mounted on a sliding track (ST) via rollable members (W). The sliding track is provided so as to help provide a smooth translation of the sliding window panel. The sliding track is preferably arranged within the support frame, for example within a rebate of the support frame. Where the sliding window panel of the embodiment of the security window assembly is configured to slide in a substantially horizontal direction, it can be seen that the sliding track is arranged to extend along at least a part of the lower wall of the support frame.

The sliding window panel has an inner side (3001N), an outer side (3000UT) and a peripheral edge defined by a secondary peripheral frame (310). The sliding window panel is mounted in the support frame such that, when the assembly in mounted in a wall defining an internal room space, the inner side of the sliding window panel faces inwardly towards an internal room space and the outer side faces outwardly away from the room space.

The first portion and second portion of the support frame are preferably configured such that when sliding window panel is in a closed position the fixed window panel and sliding window panel are arranged adjacent in a stepped configuration such that there is no opening aperture and the assembly is sealed. An opening aperture (600) is created as the sliding window panel slides from a closed position to an open position. It can be seen in Figures 14 that the second portion of the frame is configured such that the sliding window panel is preferably driven by the drive mechanism to slide behind the fixed window panel (i.e. across the outer side of the fixed window panel) as it moves from a closed position to an open position. The size and shape of the opening aperture varies continuously as the sliding window panel slides behind fixed window panel. The opening aperture is a maximum size when the sliding window panel arranged in a fully open position.

The ventilation panel (400) is a type of ventilation element and is provided to allow ventilation into the room when the sliding window panel is open but prevent or restrict the escape of or access to the occupant.

The ventilation panel comprises a perforated region, a mesh or a grill having a plurality of perforations or apertures. The perforations or apertures are configured to allow airflow when the sliding window panel is open but restrict or inhibit the passage of contraband or unsuitable items to and from the occupant. Thus, contraband etc. may not be transferred to and from the occupant via the security window assembly, even when the sliding window panel is arranged in an open position.

In the embodiment depicted in Figures 13 to 15 the ventilation panel has a panel-like structure with an inner side (4001N) and an outer side (4000UT) and a peripheral edge. The ventilation panel comprises a secondary peripheral frame. As discussed previously, the ventilation panel may be substantially flexible or rigid.

The ventilation panel is pivotally mounted in the support frame. The ventilation panel is pivotally coupled to an upper wall of the support using a one or more continuous hinges.

The ventilation panel is pivotally mounted in the support frame such that it may be pivoted between a closed position and a fully open position.

In the closed position, the secondary peripheral frame of the ventilation panel is arranged in sealing relationship with the support frame so as to restrict or prevent access across the opening aperture.

In the open position, the ventilation panel is arranged so as to allow access to an inner region of the assembly and/or the sliding window panel. It will be understood that, depending on the location of the sliding window panel, access may also be allowed across the opening aperture.

The ventilation panel is preferably pivotally mounted in a third portion of the support frame. The third portion of the frame preferably has a third internal rebate to permit the ventilation panel to be securely received in the frame during assembly. The ventilation panel is pivotally mounted in the support frame such that the inner side (4001N) faces inwardly towards an internal room space and the outer side (4000UT) faces in an outwardly direction away from the room space.

When arranged in the closed position, the ventilation panel is configured to extend substantially parallel with respect to the inner side of the sliding element so as to prevent or restrict access from the inner side of the assembly to the interior of the support frame, the sliding window panel and/or the drive mechanism. This advantageously prevents or restricts an occupant from accessing or damaging any internal component parts or component parts mounted on the outer side of the security window assembly. For example, in the closed position the ventilation panel prevents or restricts access to the rebate of the support frame for the sliding window panel and to the actuating means etc. of the drive mechanism. By restricting access, the ventilation panel further prevents or restricts the mounting of a ligature on a projecting/protruding item of the security window assembly.

The support frame (500) is substantially rectangular in shape. In the embodiment depicted the support frame comprises a lower wall (510), upper wall (520), central wall (530) extending between the lower wall and upper wall, a first sidewall (540) and a second sidewall (550). The first portion of the support frame is defined by a first part of the lower wall, the central wall, the first sidewall and a first part of the upper wall. The second portion of the support frame is defined by the lower wall, the first sidewall, the second sidewall and the upper wall. The third portion of the support frame is defined by a second part of the lower wall, the central wall, the second sidewall and a second part of the upper wall.

The support frame is configured such that an inner side (5001N) faces inwardly towards an internal room space and an outer side (5000UT) faces outwardly away from a room space.

The first portion and third portion of the support frame are preferably configured to be adjacent and in the same plane such that the fixed window panel and ventilation panel are flush as depicted in Figures 1 Th srnn1 portion of the support frame is preferably configured to be in a parallel plane to the first portion and third portion. Moreover, the first portion and third portion are configured towards the inner side of the support frame and the second portion is configured towards the outer side of the support frame such that, depending on its position, the sliding window panel appears to be behind the ventilation panel and/or fixed window panel when viewed by an operator located in the room space.

The support frame is preferably manufactured from a material that is resistant to deformation and/or breakage upon impact. For example, the support frame is manufactured from steel or aluminium.

The drive mechanism (1) is configured to reciprocately drive the sliding window panel between a closed (first) position and a fully open (second) position and any position there between as an occupant of the room rotates the handle in a given direction. As a result, the occupant cannot over rotate the handle and subsequently damage or break the drive mechanism.

FURTHER EXPLANATION OF THE INVENTION IS PROVIDED BELOW

The present invention relates to a sliding glazed assembly (such as a window or patio door) with a quick release panel to provide access to all glazed units within the assembly.

For the purpose of this document, an opening or moving element may be considered to be any panel-like member that is configured to move between a first position and a second position and to any position there between. The opening or moving element may be a closure panel-like member, such as a sliding window, which can slide between a closed position and an open position.

Sliding windows are used in a wide selection of buildings, from residential to commercial. They can be found with anything from one to multiple openings. It is growing increasingly common for the open area created by the opening or moving element moving between a first position and a second position to be covered with a protective panel, this could be a perforated panel, mesh, wire etc. This will change depending on the requirements of the panel, but all will allow sufficient natural light into the room and for ventilation to flow from one side of the opening to the other when the opening or moving element is in an open position. The protective panel can be fitted internally, externally or anywhere in between the sliding window assembly and can be used for a number of reasons, security, anti pest, anti contraband, etc. A major problem encountered with the inclusion of a protective ventilation panel is the restricted access to all faces of the glazed units that are part of the sliding window assembly, whether they are fixed or openinri nr mniinn elements. For example, if the protective ventilation panel is on the internal side of the sliding window assembly alongside a fixed element, with the opening or moving element moving between a first position a second position and any position in between, on the exterior of the room. The addition of the protective ventilation panel means that access to the internal face of the exterior opening or moving element is not possible unless the protective ventilation panel, fixed unit or opening or moving element is removed from the assembly. Resulting in the cleaning of the internal face of the opening or moving element extremely difficult and a costly exercise, especially where the window is being used in secure areas, is prone to excess or deliberate dirt, or a combination of both.

The present invention seeks to remove the difficulties described above and ensure that all areas of the sliding window can be reached for things such as maintenance, cleaning, repair, etc, without the disadvantage of having to dismantle aspects of the assembly.

Typically, a sliding window assembly will be mounted within an opening of a building. According to the present invention the sliding window assembly is made up from an outer frame housing a fixed element. The opening or moving element sits within the outer framing, configured to move between a first position and a second position and to any position there between, parallel to the fixed element. The protective ventilation panel is secured in a sub frame, which sits directly in front of or behind of the opening or moving element when in its fully closed position.

The sub frame incorporating the protective ventilation panel of the present invention is held in place within the opening created by the outer frame and the fixed element via two slide stay friction hinges, one down each side of the sub frame and the edges within the opening where the sub frame and protection panel sits. The two slide stay friction hinges will allow the protective panel within the sub frame to swing out from the top, from a first position (i.e., sub frame and protection ventilation panel in the fully closed position) to a second position (i.e. sub frame and protection ventilation panel in the fully open position), creating an opening that can be reached within for cleaning etc of the internal face of the external opening or moving element.

In certain instances the protective ventilation panel is put in place for security reasons. Two of the main reasons include preventing the room occupant escaping or prevention of the passage of contraband from inside to outside or vice versa. If this is the case the protective ventilation panel needs locking off', stopping the room occupant freely opening the protective ventilation panel and therefore eradicating the initial purpose. According to the present invention the protective ventilation panel within the sub frame, once in it's fully close position, is held in place with a standard dead lock, combined with the friction stays, resulting in the sub frame of the protective ventilation panel sitting tight against the outer frame with the lip of the sub frame creating a seal between the sub frame and the outer frame when the protective ventilation panel is in the locked off position.

If the sliding window assembly is going in a location where ligature would be of risk, the lip at the top of the sub frame member over the outer frame will be of distance so that once the protective ventilation panel is in the fully closed position it will be tight with the top of the window, taking a potential ledge out of the view of the room occupant and increasing the difficulty of successfully making a ligature point from the seal between the sub frame and the outer frame.

Depending if the protective ventilation panel is on the exterior or interior face the opening or moving element may be actuated by either manually pushing or pulling the element in a given direction such that it moves or slides between a first and second position. Or alternatively the opening or moving element many be controlled via a manually or remotely operated mechanism.

For a better understanding of the invention and to show how it may be carried into effect reference shall now be made, by way of example only, to the accompanying drawings in which: Figure 1 depicts an internal and external view of the security window assembly incorporating the present invention with an external opening or moving element and a manually operated opening mechanism.

The current invention relates to a sliding window assembly (1) incorporating an easy release panel (2) so that access can be gained to all surfaces. The sliding window assembly (1) comprises an outer frame (3), which houses a fixed unit (a non ventilating part) (4) an opening or moving element (5) and a protective ventilation panel (6) within a sub frame (7).

In the present invention the opening or moving element (5) is slidably movable parallel to the exterior of the fixed unit (4). The opening or moving element (5) when in the fully closed position sits directly behind the protective ventilation panel (6). The opening of moving element (5) moves between a first position where the sliding window assembly (1) is in its fully closed position (the opening or moving element (5) is as close to the near vertical side of the outer frame (3a) as possible) to a second position where the sliding window assembly (1) is in its fully open position (the opening or moving element (5) is as close to the opposite vertical side of the outer frame (3c) as to when the sliding window assembly (I) is in its fully closed position) and anywhere in between. The movement of the opening or moving element (5) will be the difference of no ventilation into the room (the first position) and air passing through the protective ventilation panel (6) so as to provide ventilation to the room in which the sliding window assembly (1) is fitted (the second position).

Alternatively, the opening or moving element (5) may be slidably movable parallel to the interior of the fixed unit (4), with the opening or moving element (5) sitting directly in front of the protective ventilation panel (6) when in the fully closed position.

The protective ventilation panel (6) within a sub frame (7) may be a perforated panel arranged within a standard window section. The protective ventilation panel (6) may be a sheet of perforated steel, where the cut out holes have a diameter small enough to prevent the passage of goods but big enough to allow the flow of air from one side of the perforated panel to th nthr sir1 nf the perforated panel. For example, a sheet of steel perforated with holes of 3mm diameter on a 3mm pitch.

The protective ventilation panel (6) may be folded into a tray like shape, creating a lip on all four sides. The tray like shape protective ventilation panel may be of size so that it fits within the opening of the sub frame (7) member.

Preferably there will be an additional frame or retaining means (8) sat within the tray like shape protective ventilation panel (6) to aid in holding the protective ventilation panel (6) in place and increasing the attack force that the protective ventilation panel (6) has the ability to withstand. The additional frame (8) may be in the form of four lengths of box section welded together at the corners. Or alternatively, lengths of angle, t-bar etc. According to the present invention the protective ventilation panel (6) and box section frame (8) may be held in place within the standard frame that makes up the sub frame (7) via standard bead (9) and then a wedge' gasket (10) pressure fitted into the opening to aid in holding all components as one unit (sub frame (7), protective ventilation panel (6), box section frame (8), bead (9) and wedge gasket(i0)).

The protective ventilation panel (6) within a sub frame (7) may be held in place in the sliding window assembly (1) via two slide stay friction hinges (11).

According to the present invention there may be one slide stay friction hinge (ii) down each vertical edge of the sub frame (7b).

Each slide stay friction hinge (11) may comprise of 5 link arms, a driving link arm (ha), a stationary link arm (lib) and 3 driven link arms (lic, lid & lie).

The first of the slide stay friction hinges (ii) may be secured to the vertical side of the outer frame on the inner edge (3a') where the opening is via the stationary link arm (lib). The second of the slide stay friction hinges (ii) may be secured to the central section of the outer frame that aids in holding the fixed unit in position on the inner edge (3b'), again where the opening is and again via the stationary link arm (hib). The driving link arm (11 nf hnth th friction hinges may be secured to either side of the vertical sides of the sub frame (7b) on the exterior edge.

The slide stay friction hinge (ii) may be secured in place via multiple security fixings.

In the present invention a dead lock (12) is fitted within the outer frame (3).

With the protective ventilation panel (6) in the fully closed position, the dead lock (12) can be locked off', with the leaver of the dead lock (1 2a) fitting into an opening in the sub frame (7) of the protective ventilation panel (6), locking it in place. Alternatively the dead lock (12) may be fitted to the sub frame (7) of the protective ventilation panel (6) with the leaver of the dead lock (1 2a) fitting into the opening in the outer frame (3).

To move the protective ventilation panel (6) from a first position (fully closed) to a second position (fully open) so access can be gained to the inner surface (5a) of the exterior opening or moving element (5), the dead lock (12) is to be opened and the sub frame (7) and the protective ventilation panel (6) is to be moved from its first position by pulling the sub frame (7) away from the outer frame (3) towards its second position. In the said invention, the slide stay friction hinge (11) will guide the sub frame (7) down and out from a top pivot point. The movement of the sub frame (7) will be mirrored by the driving arm (ii a) of the slide stay friction hinge (ii). This will result in the first portion of two of the driven arms (lic' & lie') being rotated around fixed pivot points on the driving arm (1 ia) and the first portion of the third driven arm (lid') being rotated around a fixed pivot point on the first driven arm (ii C). The rotation of the driven arms (ii c, lid &i 1 e) will result in the second portion of the second and the third driven arms (lid" &lle") collectively sliding down the stationary arm (ii b) and the second portion of the first driven arm (Ii c") rotating around a fixed pivot point on the stationary arm (ii b). The slide stay friction hinge (ii) will hold the sub frame (7) in the position pulled to.

To take the protective ventilation panel (6) from a second position (or anywhere between the first position and the second position) tn first nnsitinn so the panel can be locked off and made a full secure unit, the sub frame (7) is to be pushed towards the outer frame (3) until in its first position. Again the sub frame (7) movements will be mirrored by the driving arm (ii a) of the slide stay friction hinge (ii), rotating the first portion of two of the driven arms (lic' & lie') in the opposite direction on fixed pivot points on the driving arm (ha) and the first portion of the third driven arm (lid' being rotated around a fixed pivot point on the first driven arm (hic). Sliding the second portion of the second and third driven arms (lid" & lie") on the stationary arm (hib) in the opposite direction and the second portion of the first driven arm (ii c") rotating around a fixed pivot point on the stationary arm (ii b). Once in said first position, the dead lock (12) is to be locked. The combination of the dead lock (12) and the two slide stay friction hinges (ii) will hold the sub frame (7) tight against the outer frame (3).

As seen in Figure 5 the opening or moving element (5) is located on the exterior of the sliding window assembly (1), to still allow control of the opening or moving element (5) from the interior of the room it may be operated via an operation mechanism (13). This may be manually, mechanically or remotely operated. Alternatively, if the opening or moving element (5) was located on the interior of the sliding window assembly (1) the operation of the opening or moving element (5) may be either controlled via manually, mechanically or remotely operated means or manually by hand, by pushing/pulling the opening or moving element (5) in a given direction such that it moves or slides between a first and second position and anywhere in between.

The outer frame (3) may be configured to receive at least a part of a peripheral edge of the opening or moving element (5).

The opening or moving element (5) is preferably slidably mounted on a sliding track (14) via at least one rollable member so as to aid the sliding motion of the opening or moving element (5) within the outer frame (3).

If a drive operation mechanism (13) is being used to control the opening or moving element (5), the handle (i3a) is preferably configured tn h iisihI nr1 accessible via a first side of the assembly. For example, the handle (13a) is preferably configured to be visible and accessible via an inner side of the assembly.

The opening or moving element (5) may comprise a glazing unit. The glazing unit preferably comprises at least one pane of security glass in order to prevent or minimise the breakage of or damage to the glazing unit.

The fixed unit (4) may comprise a glazing unit. The glazing unit preferably comprises at least one pane of security glass in order to prevent or minimise the breakage of or damage to the glazing unit.

The fixed unit (4) may be securely mounted in the outer frame (3). The opening or moving element (5) may be configured to slide relative to the fixed unit (4), preferably across an outer side of the fixed unit (4).

The box section frame (8) and the protective ventilation panel (6) may be fixed into the standard frame that makes up the sub frame (7) if additional strength or security is needed. This may be achieved with fixings, the fixings could be threaded if required, or alternatively security (anti-tamper) screws could be used.

According to Figure 6 a second embodiment of the present invention, the sub frame (7) incorporating the protective ventilation panel (6) is held in place within the opening created by the outer frame (3d) and the fixed unit (4) via hinges (15) on one of the four sides of the sub frame (7) and the outer frame (3). The hinges (15) will allow the protective ventilation panel (6) within the sub frame (7) swing out from a pivot point on one edge of the sub frame (7) from a first position to a second position, creating an opening for access to the internal face of the external opening or moving element (5).

The hinge (15) can be any hinge like assembly that will aid in swinging the sub frame (7) of the protective ventilation panel (6) away from the outer frame (3).

Preferably single or multiple butt hinges (15a) or a single or multiple piano hinges (1 5b) will be used.

As seen in figure 6, the hinge (15) mechanism may sit on the visible face of the framing. It may be preferred for the hinge (15) mechanism to be fully concealed within the framing (sub frame (7) and outer frame (3)) of the assembly as this removes any potential ligature risks.

According to the present invention the dead lock (12) could be substituted for any mechanism that will aid in the locking off of the sub frame (7) while in its fully closed position.

It can be seen in Figure 11 that if a potential ligature point is to be seen as a risk for the room occupant the overlap across the top of the sub frame (7) onto the outer frame (3) can be extended so that the ledge created across the top where the two frames meet is reduced. Preferably if this was the case the slide stay friction hinges (11) will be mounted on the two vertical edges (7b) of the sub frame from the top downwards, this will result in the sub frame (7) moving down while out at the bottom and preventing damage to any surround area but still allowing access to the interior face (5a) of the exterior opening or moving element.

According to a third embodiment of the present invention, the sub frame (7') incorporating the protective ventilation panel (6) may be a T' frames section.

The fixings may be threaded and may go through the T' section (7'), through the protective ventilation panel (6) and into the box section frame (8'), or alternatively through the box section frame (8'), through the protective ventilation panel (6) and into the T' section (7'). The exterior leg of the T' section (7') may be of size to overlap the outer frame (3) so that a seal is created between the sub frame (7') and the outer frame (3) when the protective ventilation panel (6) is in the fully closed position.

According to a fourth embodiment of the present invention, the sub frame (7") member incorporating the protective ventilation panel (6) may be a T' frame section. Figure 8 shows four lengths of T' frame section (7") making up the sub frame (7"). Within this may then sit the protective ventilation panel (6) and the box section (8"). The protective ventilation panel (6) and the box section (8") may be secured in place in the T' section (7") via multiple fixings. The fixings may be threaded and may go through the T' section (7"), through the protective ventilation panel (6) and into the box section frame (6"), or alternatively through the box section frame (6"), through the protective ventilation panel (6) and into the 1' section (7"). The overall size of the T' section (7") may be of size so that it fits within the opening created by the outer frame (3) and the fixed unit (4). Within the opening may sit a lip member (16a) or box section (16b) that may be secured in place to define the closed position of the protective ventilation panel by abutting the sub frame (7"). Hence, when the sub frame (7") is in its fully closed position a seal is created between the sub frame (7") and the outer frame (3) and the interior face is flush.

According to a fifth embodiment of the present invention, the sub frame (7") member incorporating the protective ventilation panel (6) may be an L' section.

Figure 9 shows four lengths of L' frame section (7") making up the sub frame (7"). Within this may then sit the protective ventilation panel (6) and the box section (8").

The fixings may be threaded and may go through the L' section (7"), through the protective ventilation panel (6) and into the box section frame (8"), or alternatively through the box section frame (8"), through the protective ventilation panel (6) and into the L' section (7"). The overall size of the L' section (7") may be of size so that it fits within the opening created by the outer frame (3) and the fixed unit (4). Within the opening may sit a box (16b) or an elongate member (16a) that may be secured in place to define the closed position of the protective ventilation panel. When the protective ventilation ninI htjts th box or elongate member the sub frame (7") is deemed to be in its fully closed position; a seal is created between the sub frame (7") and the outer frame (3) and the interior face is flush.

In the preferred embodiment the fixed unit (4) and the protective ventilation panel (6) sit on the interior side of the room with the opening or moving element (5) sitting on the exterior side of the room. Alternatively, the fixed unit (4) and the protective ventilation panel (6) may sit on the exterior of the room with the opening or moving element (5) sitting on the interior of the room.
