Abstract

A security door 1 comprises a steel framed door panel 2 pivotally mounted on mounting brackets 3 by way of hinge pins 4. Four locking bars 5 are mounted in channels 6 on the door panel 2 and controlled by centrally positioned locks 7. Bolts 8 extend between the two members forming each pair of mounting brackets 3. The security door 1 is mounted in doorway 9 by the mounting brackets 3 which clamp one on either side of the door frame 10 with the bolts 8. The door panel 2 can be swung closed on the hinge pins 4 such that the door panel 2 closes against the door frame 10 and the locking bars 5 and locks 7 fit within the body of the mounting brackets 3. By operating the locks 7 the locking bars 5 are caused to engage catches 11 on the mounting brackets 3 thus effectively securing the door. To open the door the process is simply reversed. <IMAGE>

Description

11security Door This invention relates to a security door for providing a secure barrier for an entrance or passageway.
Providing doors resistant to attack for the rear of shops and the like presents a number of difficulties.
The door should be strong enough to resist attack and designed so as to avoid any potential weak points such as around the hinge or lock areas. At the same time it is preferable that the door is easily installed and simple to operate in use.
According to the present invention there is provided a security door comprising a door panel and at least one pair of mounting members, the door panel being hingedly mounted on the mounting members and the mounting members forming clamp means to secure the security door in a door frame, retaining means being provided to secure the door panel, in a closed position, to the mounting members.
Preferably two pairs of mounting members are provided.
Preferably also the retaining means comprises four retaining bolts provided for securing the door panel to the mounting members at each end of one of each pair.
Preferably also the mounting members are C shaped channels within which the retaining bolts are received in the closed position of the door.
Preferably also locking means are provided for the retaining means.
Embodiments of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of a security door in accordance with the present invention; Fig. 2 is a detail end view of a mounting bracket of the security door of Fig. 1; Fig. 3 is a detail end view of a locking member of the security door of Fig. 1; and Fig. 4 is a perspective view of the security door of Fig. 1 installed in a doorway.
Referring to the drawing a security door 1 in accordance with the present invention comprises a steel framed door panel 2 and two pairs of mounting brackets 3.
The door panel 2 is pivotally mounted on two of the mounting brackets 3 by way of hinge pins 4. Four locking bars 5 are mounted in channels 6 on the door panel 2 and controlled by centrally positioned locks 7. Bolts 8 extend between the two members forming each pair of mounting brackets 3.
In use the security door 1 is mounted in doorway 9 by the mounting brackets 3. Each pair of brackets 3 clamp one on either side of the door frame 10 with the bolts 8 being tightened to provide a firm mounting.
The door panel 2 is then swung closed on the hinge pins 4 such that the door panel 2 closes against the door frame 10 and the locking bars 5 and locks 7 fit within the body of the mounting brackets 3. By operating the locks 7 the locking bars 5 are caused to engage catches 11 on the mounting brackets 3 thus effectively securing the door. To open the door the process is simply reversed.
The door panel 2 is typically manufactured from 2 mm thick steel and the mounting brackets 3 by 3 mm thick steel thus providing a solid structure having good resistance to attack.
The security door 1 has a number of advantages, The clamp fixing of the mounting brackets 3 avoids the need for permanent fastenings which would damage the surrounding brickwork. The locking bars 5 and locks 7 are totally enclosed by the mounting brackets 3 when the door is closed thus preventing tampering from inside and outside. At the same time they are easily replaceable if damage should occur. The four point locking system avoids any undue strain on the hinge pins 4.
Modifications and improvements may be made without departing from the scope of the invention. For example various different sizes and layouts can be provided to suit different applications.
