Abstract
Abstract A detachable radio mount for a vehicle comprising a dash bracket bolted or otherwise secured to the dash of a vehicle and a radio bracket bolted or otherwise secured to a radio or other communication device. Bar magnets are secured in ferrous metal brackets which are secured to the dash bracket such that a magnetic circuit is formed from the north to the south pole of the magnets increasing the magnetic flux of the magnet in the area surrounding the magnet. Ferrous metal plates having a width equal to the width of the ferrous metal brackets on the dash bracket and being approximately two times the thickness of the ferrous metal brackets are secured to the radio bracket by adhesive or other means such that magnetic force pulls the ferrous metal plates toward the bar magnets and ferrous metal brackets. A magnetic bond is formed between the magnets and the ferrous metal plates having suffcient strength to hold a radio and which may be separated therefrom only by sliding the steel plates longitudinally relative to the bar magnets. Electrical connections are provided through the ferrous metal bracket on the dash bracket and the metal plates on the radio bracket since ferrous metal is a conductor of electricity.
