Breakaway devices are used to mount objects to systems or structures (for example, cars, helmets, buildings) and prevent damage when said objects fall away from the system. Unfortunately, even in ideal scenarios, many of these devices have limitations. Breakaway bolts and shear pins have the complication of breaking and becoming unusable thereafter. Resettable mounting devices such as hook and loop fasteners, reusable adhesives, or rubber mounting devices do not provide proper stability in certain applications. Electromagnetic and electro-mechanical based devices can be quite large and expensive while requiring a power source. There is a need for a more universal and reusable breakaway mounting device.
This invention is a reusable breakaway mounting device that can be customized according to the amount of force required to break away the mounted device. There are two versions of the device. One version uses a maximum strength o-ring to prevent damage to the mounted device. The o-ring is mounted within a groove to provide stabilization while a tooth ring is tightened around the o-ring. The spacing of the teeth provides a way for the o-ring to compress and release itself when the threshold force is reached. A second version uses a magnetic field between the breakaway plate and the mounting brackets. Using magnets allows a simple way to customize the minimum breaking force that preserves the mounted device. It also allows easy resetting of the mounting bracket to its base. Each version may further include a tether to prevent loss or further damage to the high valued object. Both versions take different environments into account, such as an angular mount or underwater situations, while still providing a simple and inexpensive solution to a longstanding problem.
