Description

2362676 A SECURITY DEVICE is The present invention relates to a security

device applicable to the safety of the home and/or other building.

An external door for a home or other building, often contains one or more decorative panels. Such a decorative panel may be a solid raised panel forming an integral part of the door, and presenting no particular security problem.

Another type of decorative panel may, however, be made of a material different from that of the remainder of the door, and/or may be removable to present a security problem. Thus a home owner may inadvertently leave the keys of the door in the lock at the inside of the door. If a thief can obtain access through the door, for example by breaking through a panel or by removing a panel from the door, then the keys inside may be accessible and the door easily unlocked.

The present invention has for its aim to prevent, or at least to make more difficult, an unauthorised removal of a panel from an aperture in a door or the like, thus making it more difficult for a thief or other intruder to enter a premises in which a door or the like is fitted, and which premises might be easily entered in the manner just described.

According to the present invention there is provided a security device for use in preventing or making more difficult an unauthorised removal of a panel from an aperture in a door or the like, the security device comprising a body.which can be secured at the edge of such an aperture, and which body has an integral projection to extend into the aperture from the edge of the aperture whenthe body is secured there, the security device further comprising a clip cooperable with the projection to secure the edge of a panel between the projection and the clip, the clip being removable to facilitate removal of the panel from one side of the door or the like, whilst removal of the panel from the other side of the door or the like is prevented or made more difficult by the projection which is integral with the body.

In one embodiment the body is formed from plateform material such as, for example, hardened plated spring steel. The integral projection may be formed by bending out of the plane of the body. In some embodiments however the integral projection need not be formed out of the same material as the remainder of the body, as long as it cannot be removed therefrom.

The body may have securement projections enabling it to be driven into the material of the door or the like at the edge of the aperture. When the body is formed from plate-form material, these securement projections may be formed by bending out of the plane of the body, possibly in the opposite direction to that in which the integral projection is bent.

The clip may also be formed from plate-form material such as, for example, hardened plated spring steel.

The clip may have two portions, preferably extending substantially at right angles to one another, one portion of which can engage with the body of the security device, while the other portion of which cooperate with the integral projection of the body to secure the edge of the panel as aforesaid.

The body may have lugs to secure the clip to the body, for example by the one portion of the clip, and preferably one of these lugs prevents, or makes more difficult, withdrawal of the clip from the body in a direction away from the panel without the use of a tool.

A packer element may be employed between the body is and clip, and the edge of the panel, in a direction from the edge of the aperture to the edge of the panel, the packer element being located between the integral projection and the clip.

Preferably the packer element has projections which locate with the body and/or clip to prevent the packer element being displaced in a direction along the length of the edge of the aperture, and can also have extensions to provide buffers between the opposite faces of the panel and the body projection and the clip of the security device. This latter feature is particularly useful where the panel is made of glass, the security device is made of metal, and the packer element is made of plastics or other cushioning material, whereby the plastics extensions can provide advantageous cushioning or buffering between the glass of the panel and the metal of the security device.

In an alternative embodiment of the invention, the body is made of plastics material with a platform above which a lug or lugs extend to hold the cooperable clip onto the platform, with preferably a lug being provided on a wall projecting upwardly from the platform, advantageously a plurality of lugs provided on two walls projecting upwardly from the platform along two respective sides of the platform, preferably with two lugs provided at or adjacent to the ends of said two walls.

The plastics material body may incorporate a metal clip to prevent or make more difficult damage to or destruction of the body.

The metal clip may be of substantially Z-form, with one end portion extending against the integral projection, a central portion extending along the platform, and another end portion extending through an aperture in the platform.

The cooperable clip may be made of plastics is material also, having a flat portion to slide between a platform and the lug or lugs, and an upstanding portion cooperable in a clamping manner with the integral projection of the body.

For a better understanding of the invention and to show how it may be put into effect, reference will now be made, by way of example, to the accompanying drawings in which:

Figure 1 shows a conventional external domestic door; Figure 2 is a detail of the securement of a glass panel in the door of Figure 1; Figure 3 is a section showing how the glass panel of Figure 2 may be secured by a first embodiment of security device according to the present invention; Figures 4A, 4B and 4C show different views of a clip comprised in the first embodiment of security device shown in Figure 3; Figures SA, 5B and SC show different views of a body of the security device shown in Figure 3; Figure 6 shows a perspective view of a packer element of the security device shown in Figure 3; Figure 7 shows an enlarged perspective view of the body of a second embodiment of security device according to the present invention; Figure 8 shows, in actual size, a plan view of the security device body of Figure 7; Figure 9 shows a side sectional view of the security device body of Figure 7; Figure 10 shows a side sectional view of a clip for use with the security device body of Figure 7, 8 and 9; and Figure 11 shows a front sectional view of the clip of Figure 10.

Figure 1 shows a conventional external domestic door 1, which could be employed as the front door of a is house.

Figure 1 shows a door I made, as is presently conventional, from an inner frame (not shown) extending around the outer edge of the door, with skins of plastics material (or steel) forming the two larger outer faces (front and back faces) of the door being mounted on the inner frame. Heavy plastics foam is injected between the two outer skins and the inner frame of the door, to provide a filling of the door between its front and back faces.

Two decorative panels 2 and 3 are formed in the outer skin which is to provide the external surface of the door, these panels 2 and 3 being provided by indentations and/or raised surfaces of the plastics skin. The decorative panels 2 and 3 are integral with the construction of the door and provide no particular security risk.

Panels 4 and 5 in the upper half of the door, however, provide more of a security problem. Details of the securement of panel 5 have been shown to illustrate this.

Thus, panels 4 and 5 are decorative double-glazed panels to which decorative patterns have been applied. Each such panel is retained in a corresponding aperture cut into the finished door.

Considering panel 5 for example, there has to be provided a means of securing the double-glazed panel 5 in the corresponding aperture cut into the door. This is not easy to achieve, since the edge of the aperture consists of the foam filling of the door, and it is not easy to secure a glazed panel direct to the foam aperture edge. A silicon securement could be employed, but it has been found not to be stable.

What is conventionally employed to overcome this problem is a so-called cassette frame having two halves which sandwich the glazed panel 5 between them, and which attach to the plastic skins surrounding the aperture which accommodates the panel 5.

Such a cassette is shown as having two frame halves 6 and 7, with frame half 6 being located at the external side of the door, and frame half 7 at the opposite or internal side of the door. These two frame halves 6 and 7 sandwich the glazed panel 5 between them, and also the rim of the accommodating aperture in the door 1.

The frame halves 6 and 7 are secured together by screws (not shown) which are screwed-in from the internal side of the door, and which extend through bosses 8 at the inner side of frame half 7, and into corresponding bosses (not visible in Figure 1) at the inner side of the frame half 6.

Tightening the screws into the bosses in the frame half 6 draws the two frame halves 6 and 7 towards one another, sandwiching tightly between them the panel 5 and the rim of the aperture containing the panel 5.

The screw heads cannot be accessed from the outside of the door 1, meaning that frame half 6 and the panel 5 cannot be easily removed from the outside of the door 1 when the door 1 is closed.

Figure 2 shows in more detail how the two frame halves 6 and 7 sandwich the double-glazed panel 5 between them and grip at the rim or edges of the associated aperture, by showing a section through the door 1 and the panel 5 at the location of a cooperating pair of the bosses 8.

The outer and inner frame halves 6 and 7 respectively are shown, with bosses 8 facing one another at the edge of the aperture wherein the panel 5 is secured.

Raised inner edges 9 of the frame halves 6 and 7 sandwich the glazed panel 5 between them, via polymer or rubber edgings (shown in hatched close-together lines) applied to both sides of the entire outside edge of the panel 5 as is conventional.

The inner and outer skins 10 and 11 of the door 1 can be seen in Figure 2, with the heavy injected foam being shown between the skins 10 and 11 in hatched more spaced-apart lines.

A screw (not shown) is screwed from the inside of the door, through the boss 8 on the inner frame half 7 and into the boss 8 on the outer frame half 6. The screw is tightened together with corresponding screws through the other bosses 8 as shown in Figure 1, to secure the frame halves 6 and 7 and the glazed panel 5 in place in the corresponding aperture provided in the door 1.

The head of the screw is disguised at the internal side of the door so as not to be unsightly, whilst the screw head cannot be accessed from the external side of the door when the door is closed.

The problem is encountered, however, that the determined thief is usually able to lever the outer frame half 6 away from the external surface of the door 1, for example by inserting a screwdriver or other implement between the outer frame half 6 and the outer plastics skin 11, and by simply levering the bosses 8 thereon away from the distal ends of the screws which extend into those same bosses 8.

Once the external frame half 6 is removed, the glazed panel 5 can easily be withdrawn towards the external side of the door, leaving the remaining aperture free for the insertion of the thief's arm. The thief then may be able to enter the house, by operating the door keys if they have been left in the lock at the inner side of the door, or if they are accessible on a table or elsewhere near the door. The thief can then gain unauthorised entry.

Figure 3 shows how one embodiment of a security is device according to the present invention may be employed in conjunction with the external and internal frame halves 6 and 7, in order to increase the security of the glazed panel 5.

The security device of Figure 3 is not intended to replace the arrangement of frame halves 6 and 7 etc shown in Figure 2, but is to be applied between the panel 5 and the edge of the door aperture surrounding it, at locations between the bosses 8 of Figure 2 along the periphery of the door aperture. However the frame halves 6 and 7 etc could be omitted if desired, as shown in Figure 3. This may be the case if a pleasant appearance and sealing of the panel edge against the aperture edge is not particularly wanted or required.

The security device of Figure 3 comprises a body 12 which is secured at the edge of the aperture as shown.

The body 12 is formed from hardened plated spring steel, and has an integral projection 13 formed by bending out of the plane of the body 12.

The integral projection 13 extends into the aperture from the edge of the aperture, and the security device further comprises a clip 14 cooperable with the projection 13 to secure the edge of the panel S between the projection 13 and the clip 14.

The clip 14, although secured to the body 12 by means to be described, is removable using an appropriate tool, to facilitate removal of the glazed panel 5 from the internal side only of the door. Removal of the glazed panel 5 from the external side of the door is prevented by the presence of the projection 13 which, being an integral part of the body 12, is securely fixed at the edge of the aperture containing the panel 5.

This fixed securement of the body 12 with projection 13, is achieved by securement projections 15 enabling the body 12 to be driven into the material of the door at the edge of the aperture. These securement projections 15 are formed, similarly to the integral projection 13, by bending out of the plane of the body 12, in the opposite direction to that in which the integral projection 13 is bent.

The body 12 is hammered into the edge of the aperture before the glazed panel 5 is fitted, with the securement projections 15 going into the hardened foam material and being such a width apart as to abut firmly against the inner faces of the outer skins 10 and 11.

In addition to being sandwiched between the projection 13 and the clip 14, the edge of the glazed panel 5 rests on a packer element 16 which forms part of the security device and which will be described in more detail hereinafter.

Figures 4A, 4B and 4C show the clip 14 of Figure 3 in more detail. The clip is formed, like the body 12, from plate-form material such as hardened plated spring steel, and has two portions 17 and 18 extending substantially at right angles to one another. The portion 17 engages with the body 12 in a manner to be described, while the other portion 18 cooperates with the integral projection 13 of the body 12 to secure the edge of the panel 5 as shown in Figure 3.

Figure 4A is a view of the clip 14 looking at the portion 17 thereof in plan, Figure 4B is a view of clip 14 looking along the upper surface of the one portion 17 towards the other portion 18, and Figure 4C is a side sectional view of the clip 14 and corresponds to the view of the clip 14 shown in Figure 3.

All views shown in Figure 4 indicate a slot 19 cut into the clip 14 at a rounded corner which joins the two portions 17 and 18 of the clip, that slot 19 being employed in the securement of the clip 14 onto the body 12 as will be described hereinafter.

is Figures SA, 5B and SC show the body 12 of the securing device in directions corresponding to those of Figure 4A, 4B and 4C respectively.

Figure SA looks down on the upper surface of the body 12, showing that there are four securement projections 15 at the four corners of the body 12, enabling the body 12 to be driven into the material of the door at the edge of the aperture. In this way the body 12 can be very effectively secured into the material of the door, enabling the integral projection 13 to prevent outward withdrawal of the glazed panel 5, even if the external frame half 6 shown in Figures 1 and 2 has been removed from the outside of the door 1 by a thief.

Figures SA, 5B, SC show that four lugs 20 are bent out of the surface of the body 12, enabling the clip 14 of Figure 4 to be slid along the upper surface of the body 12, with the edges of portion 17 underneath or within the lugs 20. The lugs 20 hold the clip 14 down onto the upper surface of the body 12, so that the clip 14 cannot move in a direction towards the centre of the aperture, nor in a direction along the length of the periphery of the aperture. When the clip 14 is slid fully into position, as shown in Figure 3, a further lug 21 extending upwardly from the surface of the body 12 enters the slot 19 of the clip 14, confronting surfaces of the lug 21 and the slot 19 thus preventing the clip 14 from being withdrawn in the opposite direction, without use of an appropriate tool which depresses the clip 21, by a skilled workman. In this way the clip 14 can be removed from the internal side of the door, enabling a replacement decorative panel 5 to be inserted if required, for example if the householder simply wishes to alter the pattern of the decorative panel 5, or if the panel 5 becomes cracked or broken.

11- Removal of the glazed panel 5 from outside the door 1 is, however, not possible owing to the presence of the integral projections 13.

Figure 6 shows in more detail the packer element 16 of Figure 3, which is employed between the body 12 and clip 14 on the one hand, and the edge of the glazed panel 5 on the other hand, in the direction from the edge of the aperture to the edge of the glazed panel 5, as shown in Figure 3 which shows the packer element 16 of Figure 6 in the direction indicated by the arrow in Figure 6.

The packer element 16 is made of plastics material and has elongate projections 22 at its lower edges, which locate with the lateral edges of the body 12 to prevent the packer element 16 being displaced in a direction along the length of the peripheral edge of the aperture, i.e. in the direction of the arrow shown in Figure 6.

The packer element also has rectangular extensions 23 and 24 extending along upper edges of the packer element at right angles to the projections 22.

Extension 23 is shown in its original orientation before the security device is assembled. Before such assembly, the extension 24 will be in the same orientation as extension 23.

During assembly on the other hand, the packer element 16 is located onto the one portion 17 of the clip 14, which is itself secured into the lugs 20 and 21 of the body 12, as shown in Figure 3.

Each extension 23 and 24 of the packer element 16 is bent upwardly during this procedure as shown for extension 24 of Figure 6, to provide cushions or buffers between the opposite faces of the glazed panel 5 and the projection 13 on the one hand, and the other portion 18 of the clip 14 on the other hand.

In this way, the plastics extensions 23, 24 can provide advantageous cushioning or buffering between the external glass surfaces of the glazed panel 5, and the metal of the projection 13 and clip 14.

In the embodiment of door shown in Figure 1, it has been found advantageous for the panel 5 to be rendered secure by the provision of a plurality of security devices as shown in Figure 3, located at intervals around the periphery of the panel 5.

It could be sufficient to provide six of these security devices, one at the bottom end of the panel and one at the upper end thereof, and two securing devices at each lateral side of the panel 5, inbetween the bosses 8 shown in Figure 1.

By deploying a plurality of security devices around the edge of the panel 5 (and panel 4), unauthorised removal of the panel from the outside of the door can be prevented or made more difficult as described even if the external half frame 6 of the panel cassette can be levered-off.

Thus when the half frame 6 has been levered off, the thief is then confronted by the panel 5 held-in by a plurality of security devices as shown in Figure 3, arranged around the periphery of the panel 5.

The thief cannot remove the projections 13 because they are integral with the bodies 12 which are firmly driven into the material of the door aperture by means of the securement projections 15.

Thus the glazed panel 5 is held securely around its whole periphery, being held firmly within the plane of the aperture, by the cooperation of the integral projections 13 of the bodies 12 with the clips 14 which cannot move inwardly, owing to the interlocking of the lugs 21 with the slots 19.

Faced with this situation the thief could be tempted to lever the packing elements 16 sideways, the direction along the peripheral edge of the is aperture, in the direction perpendicular to the plane of Figure 3. If he could achieve this, the glazed panel 5 would then simply sit loosely in the security devices around each edge, and could more easily be levered out. Again the thief is thwarted, however, since the provision of the projections 22, shown in Figure 6, of the packer elements prevents them being moved in that direction.

Also of course, the removable clips 14 cannot be accessed from outside the door by the thief, and so he is faced with a secure panel 5 even after removing the external half frame 6.

The thief is then faced with the decision of either attempting to break the glazed panel 5, or to give up his attempt at breaking-in. Usually the thief will not wish to attract attention by actually breaking the glazed panel 6, and will cease trying to break in to that particular building, the contents of which will therefore be safe and secure.

All these features can be equally well achieved by a second embodiment of security device according to the invention, which can be made from plastics comprising just two molded pieces. This second embodiment is shown in Figures 7 to 11, with parts thereof which are the same as those of the first embodiment of Figures 1 to 6, carrying the same reference numerals.

Accordingly, the body 12 shown in three different views in Figures 7, 8 and 9 is molded in one piece from nylon or from some other suitable plastics material.

The body 12 comprises a substantially flat rectangular platform 12a, with an integral projection 13 projecting upwardly from one end of the body 12. The platform 12a corresponds to the upper surface of the body of Figures 5A, 5B and 5C and the integral projection 13 has precisely the same function as that of the integral projection 13 of those Figures.

is Securement projections 15 project at the underneath of the body 12 of Figures 7 to 9, with two securement projections 15 extending in parallel along the two longer edges of the body 12, and with another securement projection 15 extending between them, as can be seen in Figures 8 and 9. As for the first embodiment, these securement. projections 15 enable the body 12 to be driven into the material of the door at the edge of its aperture. The securement projections 15 of the second embodiment are arranged rather differently from those of the first embodiment, with the two outer projections 15 extending across the width of the door when installed but have the same function.

Lugs 20 and 21 of the second embodiment have exactly the same function as those of the first embodiment, with the four lugs 20 being provided at. the four corners of the platform 12a provided by the body 12, and with the lug 21 projecting upwardly out of an aperture in that platform 12a, just as in the first embodiment.

In the second embodiment however, the four lugs 20 project inwardly from two side walls 25 projecting upwardly from the platform 12a at its two edges parallel with the two outer securement projections 15. Alternatively, separate lugs 20 need not be provided, and on each side of the platform 12a the two lugs 20 could be replaced by a single continuous elongate lug extending above and along the edge of the platform 12a along the associated side wall 25. Or, although not shown, a single lug or another lug could be provided along the projection 13.

Figure 8 shows reinforcing ribs 13a etc at the rear of the integral projection 13.

Figures 10 and 11 show the clip 14 which, in the second embodiment, is cooperable with the body 12 and, similarly to the first embodiment, has two portions 17 -is- is and 18 extending substantially at right angles to one another.

The portion 17 engages in the body 12 of Figures 7 to 9 by sliding forwardly between the platform 12a provided by the body 12 and the four lugs 20 just as in the first embodiment. The thickness of the portion 17, and the gap between the platform 12a and the lugs 20, should be such that the clip 14 needs to be hammered into the body 12 to assist in providing a secure fixing of the edge of the panel 5 between projection 13 and portion 18.

As in the first embodiment,-in the second embodiment also a slot or recess 19 in the bottom surface of the clip 14 engages the upwardly- projecting lug 21 in the body 12, so that surfaces of the lug 21 and the slot or recess 19 confront each other, and the upright portion 18 cooperates with the integral projection 13 of the body 12 to secure the edge of the panel 5 in a similar manner to that shown in Figure 3.

Also as in the first embodiment however, the clip 14 is removable from the body 12 by levering-off by means of a suitable tool which depresses the lug 21 from that side of the panel 5 opposite to the projection 13.

One advantage of the second embodiment over the first, is that with the second embodiment it is possible to manage without the packer 16 of Figure 6. Thus with the second embodiment the double-glazed panel 5 can rest directly on top of the plastics lugs 20 and the material interconnecting the lugs at each lateral side of the body 12, and can be sandwiched directly between the plastics integral projection 13 of the body 12 and the upwardly-extending plastics portion 18 of the clip 14. Since the second embodiment can be made entirely of molded plastics, there need be no protective material inserted between the security device and the double-glazed panel 5.

In a variant of the second embodiment it is possible to provide screwholes 26 through the platform 12a of the body 12 as shown in Figure 7. Thus in some types of door, screws can be inserted through the holes 25 into the material of the door at the aperture edge, to reinforce the securement provided by the securement projections 15.

In some embodiments it may even be possible to omit the securement projections 15 altogether, and rely only on screws through the holes 26 for securing the body 12 to the edge of the door aperture, provided the material providing the edge of the door aperture is sufficiently dense and strong.

Where securement projections 15 are provided, they can be of different lengths for different thickness of doors, such as for example 45mm, 60mm or 70mm door widths.

The second embodiment body 12 of Figures 7 to 9 can be strengthened by the incorporation of a metal clip, so that the body will not be vulnerable to extreme measures which could be taken to destroy the clip, for example by sawing across the body 12 either crosswise or lengthwise.

Thus for example a Z-shaped metal clip (not shown, for clarity) which is bent so that the two corners of the clip provide right angles, could be inserted in the body 12 with one end portion located in a shallow recess 27 in the upright integral projection 13, with its central portion lying flat along the platform 12a provided by the body 12, and with its opposite end portion being passed-through the aperture in the platform 12a from which the lug 21 extends upwards. This latter end portion of the metal clip could extend downwardly with or without the similarly- extending securement projections 15, to be driven into the door is material defining the aperture, and thus to assist in securing the body 12 at the edge of the door aperture.

Although the two specifically illustrated and described embodiments of theinvention have been described with reference to improving the security of a glazed decorative panel in the external door of a house or other building, it will be appreciated that the invention could be more broadly applied. For example, the glazed panel 5 could be any removable panel inserted in a surround, for example a window in a door or a wall.

Also of course, the protected panel need not necessarily be glazed or even transparent, the described and illustrated use to which the present invention has been put is simply that to which the applicant can presently envisage its best applicability at the present time.

The two embodiments of security device are described and illustrated herein in a particular orientation, which has made it convenient to claim the embodiments using terminology such as "under" and "upwardly" referring to that particular orientation. It is to be understood, however, that the two embodiments of security device can be installed in any orientation depending on whether the adjacent panel edge is at the top, bottom or side of the panel, and the claims are to be interpreted as covering the security device, particularly when it is installed, in any orientation.
