• a door frame 10 is fabricated from sheet steel and comprise a first channel shaped member 12 and a second cover member 14, the cover member 7
• a slot in which is mounted a rectangular cross- section elongate member 22 which can be moved from an extended or locking position, shown in the chain line 24 in Fig. 1 to a retracted position in which the outer edge 26 of the elongate member 22 lies alongside the frame cover member 14 or below it thereby allowing the door to swing past the frame and elongate member.
• the door is prevented from hinging beyond its closed position by the normal clapping strip of the frame (not shown). When locked by the security arrangement it is prevented from opening by the elongate member which overlies the inner, abutment face 18 of the door.
• the elongate member 22 is provided with two or more roller bearings 28 near its upper end 30, the bearings being spaced apart in the direction of the longitudinal axis of the elongate member by a distance which is substantially equal to the thickness of a horizontally extending mounting plate 32 fixed to the frame member 10 adjacent its upper end.
• operating pins 34 each of which carries a roller bearing 36.
• the door frame 10 is provided also with mounting members 38 in which an elongate operating bar 40 is slidably mounted for movement between a first upper extreme position (Fig. 6) to a second lower extreme position (Fig. 7).
• a spring 41 downwardly biasses the bar 40.
• the operating bar 40 is provided with a guide slot or channel 42 for each pin of the elongate member 22.
• Each guide channel 42 comprises a first section 44 extending in the longitudinal direction of the operating bar and a second section 46 which is transversely and longitudinally spaced from the first section 44 .and is joined to the first section by .an inclined mid-section 48.
• the bearings and pins 34, 36 of the elongate member 22 are mounted in the guide channels 42.
• Movement of the operating bar is caused by an electric motor 50 mounted within the frame 10 and driving an output crank 52 which has a connecting member 54 pivotally mounted thereto.
• the connecting member 54 is slidably mounted in a bracket assembly 76 mounted on the operating bar 40 and is surrounded, on the side of the bracket adjacent to the motor by a coil spring 60, the outer end of which engages an abutment 61 on the connecting member.
• the connecting member 54 has an adjustable end stop 57 at its outer end which abuts the bracket assembly 76. It will be realised that a half rotation of the crank 52 will result in movement of the operating bar 40 along its longitudinal axis and that movement of the crank through the other half rotation will result in a reverse movement of the operating bar 40.
• An electric supply is provided for the electric motor and conveniently comprises a battery 62 mounted within the frame member 10 and charging means (not shown) for the battery.
• the charging means may be solar powered or may comprise a trickle charger connected to a mains supply.
• Electronic control means 64 are provided for the motor 50. These include a pair or limit switches 66 cooperable with limit switch actuating members 68 on the operating bar 40, the limit switches 66 being located such that they sense the full extent of movement of the operating bar to cause the motor to stop.
• the actuating means comprise also a movement initiator (not shown) which may comprise a switch or a push button or a key or a magnetic swipe card or key and reader assembly or a hand-held radio transmitter and receiver assembly.
• Actuation of these means initiates a first half revolution of the motor 50.
• the actuation means include also a reed or proximity switch 68 which senses a magnet 70 mounted in the edge of the door 18 such that when the door is closed the reed switch is actuated to cause movement of the motor which ultimately causes extension of the elongate member into its locking position.
• a variable delay timer 72 is incorporated in the control means between the reed switch 68 and the motor 50 such that the locking of the door is delayed for a predetermined but adjustable time after the door has been closed. A time delay can be incorporated in an opening cycle.
• FIG. 8 An additional manually operated release mechanism shown diagrammatically in Figs. 2 to 4 by the reference 80 is illustrated in detail in Figs. 8 and 9 connects the connecting rod 54 to the operating bar 40. It comprises a bracket assembly 76 to which the other end of the connecting member 54 is attached and which is slidably mounted to the operating bar.
• the bracket assembly 76 slidably mounts a locking pin 74 which is movable from an extended position in which it penetrates an ahgned hole 82 in the operating bar 40 and a retracted position in which it is free from the hole, thereby enabling relative movement between the operating bar and the bracket and consequently the connecting member 54.
• Each cable release mechanism includes a bell crank 86 pivotally mounted to the bracket assembly 76 with one end of the crank abutting the plate 84 and the other end being attached to an operating cable 88.
• the operating cables 88 are the inner cables of Bowden cable assembhes 90, the covers of which are fixed to the bracket assembly 76.
• One of the cables 88 has an operating handle fixed to its outer end, the operating handle being mounted on the door frame on that side of the door remote from the elongate member.
• the handle can be pulled causing disengagement of the operating bar 40 under the influence of gravity and spring 41 and retraction of the elongate member 22.
• the other cable is connected to an electro-magnet which is actuated remotely by any suitable device so that, if required, the normal actuating mechanism for the elongate member can be disengaged, for 10
• the coil spring 60 surrounding the other end of the operating member 54 has a length which is equal to the length of the stroke of the operating member and is of a value which is just under the output torque of the motor. This means that if any part of the security arrangement jams during a locking operating the motor will continue to rotate and will overcome the spring force thereby imparting no movement to the bracket assembly 76 and the operating bar 40. After the first half cycle of motor rotation is completed it will move into the second half cycle thereby returning the arrangement to the position where the elongate member is retracted. This preserves the motor and enables the cause of the jam to be released without the door being locked in the closed position.
• Figs. 10 to 17 The modification of the invention illustrated in Figs. 10 to 17 is intended to for use with a hinged door which, in certain circumstances, can open in both directions.
• This application is particularly useful for a prison cell door which normally opens inwards into the cell. It is, however, convenient that on occasions, for example, if a prisoner barricades the door, that it can open outwardly.
• the door frame and hinges require modification to allow inward and outward opening and the security arrangement described above with reference to Figs. 1 to 9 is modified in a manner to be described below.
• Fig. 10 shows the door secured in a closed position by the extended elongate member 22.
• Fig. 11 shows the elongate member in a first 11
• Fig. 12 shows the elongate member in a second, fully retracted position in which it is clear of the protrusion 112 and allows the door to swing open in both the inwards and outwards directions.
• edge 16 of the door is reinforced by a profiled steel or plastic reinforcing member 114.
• Figs. 13, 14 and 15 illustrate a modified operating bar 140 and an elongate member 22 in the three positions corresponding to Figs. 10, 11 and 12 respectively, that is extended, and retracted to the first and second retracted
• the modified operating bar 140 has modified guide channels 142, the modification comprising an incline extension 144 leading from the upper end of the first section 44.
• the downward movement of the operating bar 140 to its lowermost position is activated by operation of the release cable 88 which is mounted in a modified manner to the bracket assembly 76 as illustrated in Figs. 16 and 17.
• the operating bar 140 rather than being the single member illustrated in Figs. 1 to 9 is a member fabricated from plate sections 150 in which the guide channels 142 are cut and smaller dimensioned interconnecting sections 152 to which the plate sections 150 are fixed.
• the bell crank 86 On actuation of the cable 88 by a remote release handle or other device, the bell crank 86 is pivoted to retract the pin 74 from the hole 82 and, under the influence of gravity and spring 41, the operating bar 140 is allowed to move to its lowest position, as illustrated in Fig. 15. The door can then be swung in either direction and when it is returned to its normal closed position, it is required that actuation of the motor 50 returns the elongate member 22 initially to its first retracted position, permitting one way door opening as shown in Fig. 11 and thereafter to its fully extended locking position as shown in Fig. 10.
• an auxiliary hole 182 is formed in the operating bar.
• the hole is formed by punching out three sides of a rectangle to form a tongue 184 attached by its lower end to the operating bar and deforming the tongue outwardly to form an incline surface 186 and a downwardly facing surface 190 against which the pin 74 may abut. 13
• the pawl 120 is mounted on a auxiliary bracket 176 fixed to the operating bar 140 above the slidable bracket assembly 76.
• the auxiliary bracket carries a pivot bar 128, on which the pawl 120 is mounted and a mounting arm 126 through the outer end of which passes the inner cable 88 of the release cable assembly, the outer member 90 of the cable being fixed to the bracket 176.
• a coil spring 130 surrounding the inner cable 88 is interposed between the bracket assembly 176 and the end of the arm 126 to bias the pawl to the ratchet engaging position.
• a stop 132 is fitted to the inner cable 88 and when the cable is moved to retract the pin 74 from the hole 82 during the initial release of the door the stop abuts the arm 126 to disengage the pawl 120 from the ratchet 122 against the action of spring 1 0 which normally holds the pawl in the engaged position.
• the electric motor can be replaced by hydraulic, pneumatic, clockwork or hand operated arrangements providing rotation of the crank shaft.
• the crank shaft and connecting rod assembly can be replaced by a rack and pinion or other suitable mechanical assembly.
• the guide channels can take different shapes.
• the elongate member can be arranged alongside the top or bottom of the door as an alternative to or in addition to side mounting.
• the elongate member can be mounted mid-way across the frame in a one way opening door such that in its extended position it occupies a longitudinaUy extending slot formed in the edge of the door.
• the security arrangement can include two elongate members each with its associated moving mechanism and control so that the door can be locked on both sides or either side at the operator's option.
