    Abstract: A spring actuated door opening and closing assist device is disclosed which comprises first and second tubular members positioned in telescoping relationship. Each of the tubular members has a hole formed therein in a direction transverse to the centerline of the telescoping members for receiving a shaft of a support bracket for door closing apparatus. A coil spring is located within the telescoping tubular members and extends between the respective holes in the members. The holes are bounded by internally flared portions of the surrounding tubular member which provide bearing surfaces for the shafts of the support brackets and provide abutments for the ends of the coil spring whereby the operation of the device is relatively smooth and quiet and yet the device can be relatively inexpensively manufactured.
