The interlock plates control when the sliding gate can be opened and when the hinged gate and flap can be opened with the sliding gate closed.
In Figure 11, the mechanism is shown with the gate in POSITION III where the sliding gate 111 is in the closed position and hinged gate member 114 is at 90 degrees to the sliding gate 111 and parallel to the fixed side fence 112. The hinged frame flap is parallel to the sliding gate when in closed position. Two interlocking plates are hingedly mounted on the rail. The first interlock plate 117 moves when the hinged gate moves and is withdrawn away from the hinged gate 114. A control rod 119 locks the hinged gate locking 1S handle 115a and the second interlock plate 118 remains fixed when the hinged gate 114 gate is moved to open position.
In Figure 12, the mechanism is shown with the gate in POSITION III where the sliding gate 111 is in the closed position and hinged flap 115 of the hinged gate members is locked to the fixed side fence 116 and both interlock 2o plates 117, 118 are clear of the back of the sliding gate 111. For operation of the lock the control rod 119 moves and withdraws the second interlock plate ro°. 118 away from the back of the sliding gate 111 which can then be opened.
In Figure 13 the mechanism is shown with the gate system in POSITION IV where the sliding gate 111 is in the open position and hinge gate 5 and flap members 114, 115 are fully extended and the hinged flap is locked to the rear post 116a of the side fence. Also shown are the previously-described two interlock plates 117, 118 which lock the sliding gate 111 in fully-open position against the front post the fixed side fence 116. In POSITION IV the 8 interlock plates 117, 118, are clear of the back of the sliding gate 111 which can now be opened.
Figures 14 to 17 show arrangements of locking integers during different positions.
3 Figure 14 is a semi-exploded perspective view showing the general arrangement of lock integers of Figures 15 to 17 and corresponding to gate system positions of Figures 4, 5 and used to lock the upright member 116a of the fixed side fence 116 to the upright member of the hinge gate flap 115 via lock actuator handle 115a and actuator control rod 127.
to Figure 15 shows the lock assembly before engagement of locking integers.
In Figure 14 also referring to Figure 15) the lock centre comprises a housing or bearing 120 housing a rotatable member 121 with a central shaft portion and upper and lower parallel-walled blocks with locking slots 122, 123 I formed therein is shown secured to an upright member 116a of the fixed side fence 116 via bracket 124. The lock centre slots are adapted to be engaged by two lugs comprising actuator-locking control rod upper lug 125 and lower lug 126 are respectively mounted on the lower end 127a of the split control rod 127 connected to the actuator handle 115a and on the upper end 127b of split actuator-locking control rod 127. The actuator- locking control rod 127 is operated by lock operator handle 115a. The control rod 127 is mounted o• through the tubular and base frame member of the hinged gate flap and controls opening movements of it. Hinged gate and hinged gate flap segments are operatively connected via a link 128 to transmit gate opening and closing and locking and unlocking movements. The control rod 119 is mounted through the base frame member of the hinged gate segment and controls movement of the interlocking plate 118. The arrangement is such that the control rod 127 can only be moved when the actuator rod lugs 125, 126 are 9 engaged into an upper and lower slot formed in a rotatable member of the lock centre. Figure 15 also shows the lock assembly components of Figure 14 before engagement but in greater detail and in particular shows two slots 122, 123 each adapted to respectively seat the upper lug 125 and lower lug 126 of the lock. Figure 16 shows the lock assembly engaged prior to being locked and Figure 17 shows the lugs 125, 126 and slots 122, 123 in engaged and locked position wherein the lugs and rotatable dual slotted block have been rotated 90 degrees with respect to the position in Figure 16 to prevent opening of the hinged gate.
Figure 16 shows the lock assembly during engagement.
Figure 17 shows the position of locking integers when engaged and locked whereby the hinged flap 115 cannot be separated from the fixed side fence 116 the sliding gate 111 can only be opened when in the position shown.
*Figure 18 shows the arrangement of the corner integers comprising IS the actuator-locking control rod 127 mounted through the base frame member *t*9*9 of the hinged gate flap 115 and controlling the movement of the lock actuator and the control rod 119 mounted within the base frame member of the hinged °.ogo gate 114 and which controls the movements of the interlocking plate 118. The link 128 operatively connecting the gate flap 115 and gate hinge 114 is also 20 shown.
The interlocking safety gating system of the invention fulfils two conditions, firstly the sliding gate cannot be opened until the hinged gate and flap assembly are locked to the fixed side fence and secondly or alternatively if the sliding gate is open the interlock plates will prevent opening of the lock S which secures the distal end of the hinged flap to the fixed side fence.
Conversely the interlock plates control two conditions namely in order to open the sliding gate it is necessary to have the distal end of the hinged flap locked to the rearwardly facing (lock) end of the fixed side fence and then to open the hinged gate and flap, the sliding gate must be closed.
