Abstract

A vent or frame pin 1 comprising a body 3 for attachment to a movable vent 9 or a fixed frame 17 as appropriate and a projection 5 extending from the body 3 for engaging a recess 19 or aperture to assist in resisting unauthorised opening of the vent 9. A significant improvement in the strength of interaction between the movable vent 9 and the fixed frame 17 is achieved by means of a vent or frame pin 1 as herein described. <IMAGE>

Description

VENTS This invention relates to vents, and in particular to a vent or frame pin which assists in resisting unauthorised opening of the vent.
Unauthorised entry into buildings via vents, such as windows, is becoming more common. As a result, manufacturers of windows and associated hardware have been for some time trying to develop ways of improving the security of a vent mounted in a fixed frame.
In the light of the foregoing, the present applicant has devised a new device which, if installed, can increase the interengagement between a movable vent and a fixed frame when the vent is in its closed position in the fixed frame, thereby assisting in resisting unauthorised opening of the vent. In this regard, a common way of forcing a vent to open from the outside is by pushing a metal bar between the vent and the fixed frame to lever the friction stay, which supports the vent, such that the friction stay shifts relative to the fixed frame. A device according to the present invention assists in preventing this approach from being successful.
Accordingly, the present invention provides a vent or frame pin comprising a body for attachment to a movable vent or a fixed frame as appropriate and a projection extending from the body for engaging a recess or aperture associated with the other of the vent or frame such that, when the movable vent is in its closed position in the fixed frame, the projection of the pin engages the recess or aperture to assist in resisting unauthorised opening of the vent.
A device according to the present invention is extremely simple to manufacture, easy to install and yet provides a significant increase in the strength of a vent mounted in a frame. Further, if a plurality of devices according to the present invention are used, the strength of the vent in a fixed frame can be increased significantly.
Preferably the body includes two or more fixing holes for receiving screws to enable the pin to be attached securely to a movable vent or a fixed frame.
The projection in use may engage a recess in a fixed frame of a vent. Alternatively, the projection may engage a keep mounted on a fixed frame of a vent.
If the projection engages a keep mounted on a fixed frame of a vent, the keep is preferably an end cap (or at least formed integrally with the end cap) of a friction stay supporting the vent.
More preferably, the projection in use passes through a keep mounted on a fixed frame of a vent and engages a recess in the fixed frame. In this way, increased locking between the vent and the fixed frame is achieved.
The pin is preferably manufactured from engineering thermoplastic or metal. Any other suitable material can, of course, alternatively be used.
According to another aspect of the present invention, there is provided a vent including one or more vent or frame pin as herein claimed.
Specific embodiments of the present invention are now described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is a sectional side view of an embodiment of the present invention mounted on a movable vent which is itself supported by a friction stay; and Figure 2 is a sectional side view of the vent pin shown in Figure 1, but wherein the engagement of the projection of the vent pin with the fixed frame is achieved in a different fashion.
With reference to Figures 1 and 2 of the drawings, a vent pin 1 comprises a body 3 and a projection 5 extending substantially perpendicularly to the body 3. The widths of the body 3 and the projection 5 are as large as possible, to provide as much strength as possible, without being too large that they impair the opening and closing of the vent.
Two fixing holes 7 are provided through the body 3 to enable the vent pin 1 to be fixed by means of screws (not shown) or the like to a movable vent 9, such as a window.
The movable vent 9 is mounted on a vent arm 11 of a friction stay of any well known kind. The friction stay shown in the drawings comprises a support track 13, an end cap or keeper 15 and a vent arm 11. As will be appreciated, the vent arm 11 is mounted to the support track 13 by means of a slider and a plurality of links (not shown) which allow the vent arm 11 (and hence the movable vent 9) to move from a position overlaying the support track 13 to a position angled thereto (i.e. when the vent is open).
When the vent 9 is in its closed position, an end of the vent arm 11 is received in the end cap 15 of the friction stay. This engagement of the vent arm 11 in the end cap 15 helps both to increase the pull-in of the vent 9 into its fixed frame 17 and also to assist in preventing unauthorised entry through the vent when the vent is closed.
The vent pin 1 also assists in preventing unauthorised entry through the vent by means of the projection 5 engaging a recess 19 in the fixed frame 17, as shown in Figures 1 and 2. In Figure 2, however, the projection 5 also passes through an upstanding portion 21 of the end cap 15 before entering the recess 19 in the fixed frame 17. As a result of this, additional interlocking of the movable vent 9 with the fixed frame 17 is achieved.
As shown in Figure 2, a tongue 23 of the end cap 15 extends into the support track 13 of the friction stay and is either riveted thereto or secured to the fixed frame 17 by means of a screw 25 passing through the tongue 23 and the base of the support track 13. Thus, the end cap 15 is securely fixed to the horizontal portion of the fixed frame 17 and also to the vertical portion of the fixed frame 17 by means of the projection 5 engaging the recess 19 after passing through the upstanding portion 21. Hence, the interengagement of the movable vent 9 with the fixed frame 17 is significantly increased and no longer relies upon the sole strength of the fixings attaching the support track 13 to the fixed frame 17.
Although only one position for mounting the vent pin 1 is shown in the drawings and described herein, a vent pin according to the present invention could be mounted at any appropriate position on a movable vent 9. Furthermore, a frame pin, essentially equivalent to the vent pin 1, could alternatively be used wherein the frame pin is mounted on the fixed frame 17 and engages a recess or aperture (corresponding to the recess 19 or aperture through the upstanding portion 21 of the end cap) associated with the movable vent 9, whilst still incorporating the essence of the present invention.
Furthermore, if an end cap of a friction stay is well secured to a portion of a fixed frame 17 of a vent, it would be possible for the vent pin 1 simply to engage in a recess in a portion of the end cap without physically entering the fixed frame 17. In such an embodiment, it would, of course, be unnecessary to provide a recess in the fixed frame, which may be undesirable in certain circumstances. In another instance, a vent pin 1 according to the present invention could simply engage a separate keeper (not shown) mounted on a fixed frame of a vent, which keeper is specifically designed and configured to receive the projection 5 of the vent pin 1. In such an embodiment, mounting of the vent pin 1 may be simplified.
It will of course be understood that the present invention has been described above purely by way of example, and that modifications of detail can be made within the scope of the invention.
