Detailed Description of the Preferred Embodiment

As shown in Figure I, the security apparatus I comprises a keep plate 2 and a hinge 3. The hinge 3 is preferably a piano type hinge and extends along the full length of the door 5. The hinge 3 is rebated in the door 5.

The keep plate 2 extends along the door frame 4 and corresponds to the length of the hinge 3.

In one embodiment of the invention, the keep plate 2 may be integral with the door frame 4. The door is attached to the door frame 4 at its opposite side by a hinge 6. The hinge 6 is also preferably a piano type hinge and extends along the full length of the door 5.

As shown in Figure 2 the hinge 3 comprises plates 3a and 3b. Plate 3a is bolted to the door 5 and plate 3b extends towards the keep plate 2. The keep plate 2 is preferably L-shaped. One end of the keep plate 2 is turned back on itself, to form a channel 7into which plate 3b extends. When the door 5 is closed and locked, pins 8 move towards the keep plate 2, pushing the plate 3b. The end of the plate 3b is inside the channel 7, which prevents the door from being pushed open because the movement of the end of the plate 3b is restricted by the wall or walls of the channel 7.

A spring steel clip 9 prevents dust from entering through the gap between the door 5 and door frame 4. It also prevents fingers being trapped in the door and pushes against the door to prevent rattling. The spring steel clip may be a hinged clip comprising a biasing means II. The biasing means 11 positions thc spring stccl clip 9 such that it pushes against thc door and the plate 3b is pushed against a wall of the channcl 7. To open the door, the door must first be pulled towards a user. This causes the spring steel clip 9 to pivot and the plate 3b to exit the channel 7. As the user unlocks the door using a key and handle, the pins 8 are retracted, pulling the plate 3b clear of the channel 7.

If forced entry of the door 5 is attempted, the plate 3b will be pushed further into the channel 7.

This will prevent the door from being pushed open, due to the resistance of the plate 3b against the channel 7 and or the wall of the keep plate 2a.

The channel 7 may be arranged such that projections such as teeth (not shown) arc pushed into recesses (not shown when forced entry is attempted. This means that the apparatus I becomes more resistant to attack when the door 5 is being forced open.

In an embodiment of the invention, a number of hinges 3 and/or hinges 6 may be provided so that if a hinge 3 or 6 is broken, the door 5 will remain secure at the other hinge points.

As shown in Figure 1, the security apparatus I may comprise a number of security bars 10, which arc applied to a door 3. The security bars 10 may be inserted inside the door 5 by drilling holes through the door 5, coating the bars 10 in resin and inserting the bars through the holes. The resin then sets when the bars are in place and helps to prevent splintering of the door 5 if attacked. The bars 10 are preferably steel bars and provide a strong metal skeleton, which strengthens the door.

The bars 10 may extend along substantially the entire height or width of the door as shown in Figure The bars 10 may alternatively be applied to the exterior or intcrior surface of the door and may be covered with cladding to improve the aesthetic appearance of the door 5.

The bars 10 may be arranged such that they are substantially aligned with existing dividing bars or portions of the door.

The ends of the security bars 10 may protrude beyond the edge of the door and form bolts which can he used in the locking mechanism of the door 5.

The security bars 10 may be attached to the hinge 3 or hinge 6, forming part of the security system for protecting the door.

The security apparatus 1 may be applied to windows and other openings in buildings, as well as to doors.

Figures 3a and 3b show an alternative arrangement of the locking mechanism of the security apparatus 1.

Plate 3a of the hinge 3 and a bracket 12 are bolted to the door 5. Plate 3b of the hinge 3 extends towards the keep plate 2.

One end of the keep plate 2 is turned back on itself to form receiving portion 7'.

When in a locked position as shown in Figure 3b. The end of the plate 3b extends inside the receiving portion 7', which prevents the door from being pushed open because the movement of the end of the plate 3b is resthcted by the wall or walls of the receiving poruon 7'. In an unlocked position as shown in Figure 3a, the plate 3b is in a position free of the receiving portion 7'.

In the embodiments shown in Figures 1 to 3b, the keep plate 2 is secured to the frame of an opening such as a door frame and the hinge 3 is secured to a door. However, in alternative embodiments, the hinge 3 may be secured to a frame and the keep plate 2 could be secured to a door or window.

The receiving portion 7' which forms is integral with the keep plate 2. The receiving portion 7' extends at an angle to the frame or door to which it is attached @nd at an angle from the rest of the keep plate 2) such that in a locked configuration it interferes with the plate 3b. When the end of the plate 3b engages the receiving portion 7' of the keep plate 2, the force exerted is in a direction that opens the hinge 3.
