Draw latches, often referred to as toggle latches or catch latches, are mechanical fasteners used to secure two surfaces or objects together. They consist of a few key components: a base plate, a lever or handle, a catch or hook, and sometimes a strike plate. Here's how they work: 1. **Base Plate**: This is mounted on one of the surfaces or objects that need to be secured. It serves as the foundation for the latch mechanism. 2. **Lever or Handle**: Attached to the base plate, the lever is the part that the user manipulates to engage or disengage the latch. It is typically designed for easy grip and operation. 3. **Catch or Hook**: This component is attached to the lever and is responsible for engaging with the strike plate or a corresponding loop on the opposite surface. When the lever is closed, the catch hooks onto the strike plate, securing the two surfaces together. 4. **Strike Plate**: Often mounted on the opposite surface, the strike plate provides a stable point for the catch to engage. It ensures that the latch holds the surfaces tightly together. **Operation**: To secure the latch, the user pulls the lever, which moves the catch into position over the strike plate. As the lever is pushed down, the catch engages with the strike plate, creating tension that holds the surfaces together. This tension is maintained by the mechanical advantage of the lever, ensuring a tight and secure closure. To release, the user lifts the lever, disengaging the catch from the strike plate, allowing the surfaces to separate. Draw latches are commonly used in applications requiring frequent access, such as toolboxes, cases, and industrial equipment, due to their ease of use and reliable securing mechanism.
