Description

Locking Cluster and Drive Line Connector
Technical field
The invention relates to lock assemblies and/or mechanisms for doors and windows. Specifically, the invention relates to, but need not be limited to, multi-point lock assemblies and/or mechanisms for doors or windows of buildings.
Background
Multi-point lock assemblies used in doors and windows typically comprise a plurality of locking means, each being spatially distributed on the door or window to provide a plurality of locking points for the door or window. Each locking means may be, for example, a bolt or hook and may be configured to engage with a corresponding feature of a door or window frame.
In addition, locking assemblies for doors and windows are required to withstand a particular force that may be specified in associated standards (e.g. PAS 3621:2011) in order to provide security against forced entry to a building.
Multi-point lock assemblies may also comprise a guide, such as a guide pin. The guide is configured to interact with a corresponding feature of door or window frame so as to align the door or window correctly in the door or window frame. In sliding doors or windows, the guide may be a guide pin configured to locate within a recess or aperture within the door or window frame. The guide may therefore align the locking means of the door with the corresponding feature of the door frame.
Summary
The inventors have appreciated that the strength of a door or window locking assembly may be increased by providing a plurality, or cluster, of locking means at each locking point of a multi-point locking assembly. That is, the force that each locking point of a multi-point locking assembly can withstand may be increased by providing a plurality of locking means at each locking point. For the purposes of assessing a door or window against a standard, such as PAS 3621:2011, each cluster is considered as a locking point.
In addition, guides, such as guide pins for example, used in multi-point locking assemblies may become ineffective, or have reduced effectiveness if a door or window, or a corresponding frame, moves or settles after fitting. In such cases, the guide pins may not be correctly seated in a corresponding feature of the frame when the door or window is closed. Also, if a guide is spatially separated from a locking point then even when the guide is located within the corresponding feature of the frame the spatially separated locking point may not be correctly positioned to engage with its corresponding feature of the frame.
Reference is made herein to a door locking assembly and it is noted that the features of such locking assemblies may apply equally to a window locking assembly. Further, it is noted that a locking means may comprise any means of preventing a door or window from being opened. For example, a locking means may comprise a locking pin and corresponding recess or aperture configured to receive the locking pin to resist outward or inward movement of the door or window. A locking means may also comprise a hook or other feature configured to engage with a corresponding recess to resist lateral (e.g. sliding) movement of the door or window.
According to a first aspect of the invention, there is provided a locking assembly for a door or window, the locking assembly comprising: a plurality of locking points spatially separated from each other, wherein the plurality of locking points each comprise a plurality of locking means configured to interact with corresponding features of a door or window frame to prevent opening of the door or window.
Each locking point may comprise a guide configured for cooperation with a corresponding feature of the door or window frame to align the door or window and the door or window frame.
The guide may comprise a guide pin configured to mate with a corresponding recess in the door or window frame.
The locking assembly may be for use with a sliding door or window.
The locking means may comprise a hook configured to engage with a recess in the door or window frame. The hook may comprise laterally extending flanges configured for sliding engagement with a corresponding slot in the door or window frame. The hook may further comprise a vertically extending hook member. The hook may be configured to resist in-plane movement of the door or window when the hook is engaged with the recess.
The plurality of locking points may each be spatially separated from a locking gearbox. The locking gearbox may be operable between locked and unlocked positions, the locking assembly further comprising a drive line connector between the locking gearbox and the at least one locking point configured to actuate the plurality of locking means on operation of the locking gearbox.
The drive line connector may comprise formations, at least one formation being configured to actuate the plurality of locking means at each locking point. The formations may comprise edge formations. The formations may comprise serrations running along at least part of the length of the drive line connector. The serrations may run along the entire length of the drive line connector.
The drive line connector may comprise frangible sections for adjusting a length of the drive line connector. The frangible sections may be provided by the formations.
The locking assembly may further comprise at least one vertically extending shoot bolt configured to engage with a corresponding recess in the door or window frame, and configured to be actuated by the drive line connector on operation of the lock gearbox.
Brief description of the drawings
Exemplary embodiments of the invention are described herein with reference to the accompanying drawings, in which:
Figure 1a is a perspective view of part of a locking assembly;
Figure 1 b is a front view of part of a locking assembly;
Figure 1c is a side view of part of a locking assembly;
Figure 2 is a section through a locking means of a locking assembly; and Figure 3 is an end view of a locking means;
Detailed description
Generally, disclosed herein are methods and apparatus for improving the strength and/or ease of fitting and/or operation of a locking assembly. Exemplary locking assemblies comprise at least one locking point that is spatially separated from a locking gearbox. Exemplary locking assemblies may be multi-point locking assemblies. The at least one locking point of exemplary locking assemblies comprises a plurality, or cluster, of locking means. This increases the force that each locking point can withstand and therefore increases the security of a door or window to which the locking assembly is fitted.
In exemplary locking assemblies, each locking point comprises an associated guide, such as a guide pin. As a guide pin is positioned at each locking point, the plurality of locking means of the locking point can be more accurately aligned with corresponding features of a door or window frame.
As used herein, the term “spatially separated” when used in respect of a locking point and another feature of a locking assembly encompasses a locking point that is at a different location on a door or window than the other feature. In exemplary locking assemblies, when a locking assembly is fitted to a door or window, a locking point may be spatially separated from a locking gearbox or another locking point when it is at a different location on the same edge of the door or window, or when it is positioned on a different edge of a door or window. In exemplary locking assemblies, a locking point may be spatially separated from
As used herein, the term “locking point” encompasses a separate and distinct region of a locking assembly at which at least one locking means is provided. A locking point region may cover a length in a range from 0% to 15% of the length of a locking edge of a door or window. A locking point region may cover a length in a range from 0% to 10% of the length of a locking edge of a door or window.
Figures 1a-c respectively show a perspective view of a section of a locking assembly 100, a plan view of a locking assembly 100 and a side view of a locking assembly 100. Referring to Figures 1a-c, the locking assembly 100 comprises a plurality of locking points 102, although only a single locking point is shown in Figures 1a-c. The locking point comprises a plurality of locking means 104. In the exemplary locking assembly shown in Figures 1a-c the locking point 102 comprises two locking means 104, which are hooks. The term “hooks” will be used in place of locking means herein for clarity although it is noted that other locking means may be used.
As explained above, the locking point 102 is a region of the locking assembly 100 that is considered to provide a single locking point, although in the locking assemblies disclosed herein, the locking point 102 comprises a plurality of hooks 104. In exemplary locking assemblies, a locking point may be defined as a plurality of locking means 104 associated with each other by being proximal to each other. The hooks 104 are configured to engage with corresponding recesses and/or slots in a door or window frame, as explained in greater detail below.
The locking point 102 comprises a guide 106, which in the exemplary locking assembly 100 of Figures 1a-c is a guide pin. The guide pin 106 is configured to mate with a corresponding recess in the door or window frame and aids the alignment of the door or window to which the locking assembly 100 is fitted within the door or window frame. In exemplary locking assemblies, there are a plurality of guide pins 106 (or other guides) and each guide pin 106 is associated with a locking point. By including a guide pin for each locking point, alignment of the hooks 104 with the corresponding recesses and/or slots in the door or window frame is aided.
The locking assembly 100 further comprises a face bar 108 that is configured to be fixed to a locking edge of a door or window. A locking edge of a door or window is that edge on which the primary locking apparatus are fitted. In the case of sliding doors or windows, the locking edge is that edge of the door or window that slides towards the frame and eventually contacts the frame on closing.
The guide pins 106 are fixed in relation to the face bar 108. The face bar 108 comprises apertures therethrough, in which the hooks 104 are mounted. The apertures 110 are configured to allow movement of the hooks 104 between unlocked and locked positions, wherein the hook engages with corresponding features of the door or window frame in the locked position. The face bar 108 may be configured to run substantially along the entire length of the locking edge of a door or window. Accordingly, the face bar 108 may comprise further apertures 110 and guide pins 106 defining further locking points 102 that are spatially separated from other locking points. A drive line connector 112 is placed behind the face bar 108. The drive line connector 112 is configured to actuate the hooks 104 between the unlocked and locked positions. The drive line connector 112 therefore comprises formations configured to interact or engage with the hooks 104. In the exemplary locking assembly 100 of Figures 1a-c, the formations comprise apertures through which the hooks 104 are mounted and secured to the drive line connector 112. In other arrangements, the formations may comprise edge formations, as explained in greater detail below.
The locking assembly 100 may also comprise a locking gearbox (not shown) positioned in a central region of the locking edge of the door or window. The locking gearbox, in exemplary locking assemblies 100, may provide the point at which a user of the door or window may operate the locking assembly. The locking gearbox is operable between unlocked and locked positions. The locking gearbox may be positioned at a point on the locking edge of the door or window. The locking gearbox may be positioned at one of the plurality of locking points 102.
The drive line connector 112 may be configured to cooperate with the locking gearbox to translate movement of the locking gearbox to the plurality of hooks 104 at a locking point 102. The drive line connector 112 may therefore be configured to actuate the hooks 104 between the unlocked and locked positions upon operation of the locking gearbox between its unlocked and locked positions.
The hook 104 is configured to resist in-plane movement of the door or window within the door or window frame when engaged with a corresponding recess and/or slot in the door or window frame. In-plane movement encompasses movement of a door or window in a direction that is parallel to or coincident with a plane defined by the door or window.
Figure 2 shows a section through a hook 104 along the line marked B-B in Figure 1c. It is noted that the dimensions provided on Figure 2 are exemplary only and need not limit the scope of the invention. Referring to Figure 2, the hook 104 comprises a stem 114 and flanges 116 extending laterally from the stem. It is noted that the lateral extension of the flanges 116 is with respect to the longitudinal axis of the stem 114. The hook 104 also comprises a hook member 118, as shown in Figures 1a-c. In the exemplary hook 104 of Figures 1a-c and 2, the laterally extending flanges 116 define the width of the head of the hook, however this need not be the case. The laterally extending flanges 116 could have other arrangements and may be any laterally extending feature able to be retained by a corresponding feature in a door or window frame to resist in-plane movement of a door or window.
Figure 3 shows a view looking down on a hook 104 along the longitudinal axis of the stem 114. From the perspective shown in Figure 3, the hook 104 presents a shape comprising a head section 120 and a relatively narrow section 122 extending from the head section. The head section 120 sits generally at a distal end of the stem 114 and comprises the laterally extending flanges 116. The laterally extending flanges 116 determine the width of the head section 120. The narrow section 122 comprises the hook member 118, which extends vertically from the head section 120, either upwards or downwards when the locking assembly 100 is fitted to a door or window, which is in turn fitted within a frame. As shown in Figure 3, the profile of the hook 104 presented to the door or window frame is substantially that of a traditional key hole, that is, a wide section (head section 120) and a relatively narrow section 122 extending therefrom.
It is noted that relative terms such as vertical, horizontal, lateral, up, down etc. are used herein to aid description and need not limit the scope of the invention.
The hook 104 is configured to enter an aperture within the door or window frame and comprising lips behind which the laterally extending flanges 116 and the hook member 118 may be retained to resist in-plane movement of the door or window. The aperture may have a shape substantially the same as the profile of the hook 104, as shown in Figure 3. Therefore, after the hook 104 has entered the aperture, vertical movement of the hook 104 slides the hook 104 into engagement with the lips of the aperture.
The locking assembly 100 may be fixed to a locking edge of a door or window. This may be achieved by placing the locking assembly 100 in a channel on the locking edge. The door or window to which the locking assembly is fitted may be a sliding door or window.
As the door or window is closed, e.g. by sliding in-plane, the guide pin 106 mates with a corresponding aperture or recess in a door or window frame. As the guide pin is in the proximity of the locking means 104, alignment of the locking means with corresponding features on the door or window frame is ensured. This overcomes problems associated with having a guide that is spatially separated from a locking point 102, as discussed above.
When the locking gearbox is operated between unlocked and locked positions, the plurality of hooks 104 are configured to be actuated and to engage with the corresponding features (e.g. recess or aperture) in the door or window frame to resist in-plane movement of the door or window. By having a plurality of hooks at a single locking point, the force that can be resisted by each locking point of the door or window during an attempted break-in (or a simulated break-in during testing) is increased.
The skilled person will appreciate that other exemplary embodiments may be envisaged without departing from the scope of the appended claims.
