发明名称 Theft deterrent device including a spring washer
摘要 A device to protect an article from theft is disclosed. The device includes a pointed pin member to enable attachment of the device to the article to be protected from theft. A housing disposed within the device includes a floor and a wall tapering towards a confining end. The housing includes coaxial openings for insertably receiving the pin member. A ball clutch mechanism is located within the housing and includes a plurality of balls. As the balls are urged towards the confining end of the housing, they wedge between the tapering wall and the pin member to apply increasing radial pressure against the pin member to prevent it from being withdrawn from the device. The floor includes a member which deflects downwardly upon insertion of the pin member into the housing to apply a radial force against the pin member to frictionally engage it within the device.
