Safety Latch

thingiverse

This is a safety latch designed to secure drawers, cupboard doors, or other furniture to prevent young children from opening them. Commercially there is a wide variety in the design of these latches, however, I've kept this design to it's simplest and most utilitarian form. This should be printable on most reprap printers. If your printer can't handle the screw holes at the base of the latch then you could fill them solid and screw through the plastic when attaching the latch. This is a work in progress so I welcome your feedback, improvement, and derivative designs. This thing was made with Tinkercad. Edit Part A online at: https://tinkercad.com/p/acc0011db8cb8e88 Edit Part B online at: https://tinkercad.com/p/acc0e35af491e43d Instructions Print both parts Use two small wood screws to attach part b to the door/drawer. Take care to align it so the end of the latch has less than 1mm of clearance with the surface of the furniture when the door/drawer is closed. Use two small wood screws to attach part a to the furniture surface. When the door/drawer closes the latch should clip shut as part b is secured by part a. Now to open the door/drawer you will have to flex the latch, young children struggle to do this so you have prevented them from getting access. Use Caution: Safety latches such as this design are not foolproof, and older children will learn how to open them. So it is important to keep dangerous substances out of reach or locked away.
