Patent number: RE42492Abstract: This invention describes a novel two way hinge for motor vehicle doors that hinges open at a 20 degree angle, then rotates upward 45 degrees. The motor vehicle door is maintained in the open position by a shock absorber/piston arrangement that is common in the automotive industry. The invention described herein can be installed by an aftermarket shop and/or sold as an easily installed kit. The present invention overcomes the shortcomings of existing hinges by allowing greater access for ingress and egress from existing motor vehicle doors in tight parking situations.Type: GrantFiled: April 22, 2005Date of Patent: June 28, 2011Assignee: Vertical Doors, Inc.Inventor: Robert Baum
