Commonly, barrel bolts areused to fix one 0 0 4 DOUBLE DOOR AUTOMATIC LATCH Commonly, to lock double doors, one door would need to be fixed and the other door would have a lock fitted. The lock bolt would be thrown behind the fixed door, therefore making it secure. Commonly, barrel bolts are used to fix one o ddor. These are fitted to the inside of the door. Therefore to release the fixed 00 door the user must reach in behind the door. This could involve bending down or n reaching up depending on the size of the door and the position of the barrel bolt.
IThis invention has been specifically devised to eliminate (the above) these said problems. Closing the active leaf will automatically make the other door fixed Sarid vice versa. This invention is intended for use on cupboards, cabinets and full Ssize doors that are outward opening eg.electrical risers.
An automatic latch in accordance with this invention comprises a springloaded latch, having a locking block attached in a recessed section. The automatic latch would be fitted horizontally to the inside of one door at either the top, bottom or both. A locking plate would be fitted to the frame. A striker plate would be fitted on the active door. When the active door is closed the striker plate on this door will depress the latch in on the other door. The locking block will be pushed across behind the locking plate on the frame, automatically locking that door. When the active door is open the latch and locking bolt Will return to its original position and both doors will be unlocked. The locking block is secured through the latch by a screw and is reversible for handing purposes. The latch and spring are housed in a cover, which has an open slot to allowinsertion of the locking block. This slot is wider than the locking block to allow the locking block to travel. This slot is on both sides of the cover for handing purposes. The cover is attached to a fixing plate, which has the screw mounting holes.
The latch bolt is preferably made of brass, however other materials could be used eg. mild steel, stainless steel, aluminium and plastics. The striker plate and locking plate are preferably made of stainless steel, however suitable materials could be used eg. Mild steel, brass, plastics etc. The locking bolt is preferably made of mild steel, however suitable materials could be used eg. Stainless steel, aluminium, brass, plastics etc. The cover and fixing plate are preferably made of stainless steel, however suitable materials could be used eg. Mild steel, aluminium, brass etc.
This invention may be better understood with reference to the illustrations of embodiments of the invention which: Figure 1 has orthographic views of the locking plate containing a front, side and underside view.
Figure 2 is a typical internal mounting elevation showing the latch assembly installed and in the locked position.
