<p>The rotating panel door is used for residential and business premises. This door can be open in four directions by the pressure exerted on the door handle (2). This type of door accommodated heavy traffic of personnel and also prevents any injury to persons for example using a glass door which may not open in the direction assumed by the user. Two door handles (2) act on one side of the door on levers (10, 9). Each of two pins (4) are retracted in pairs. Hence the door can be actuated on each side for opening in any manner so that the door can be opened in four directions and it can be opened by stops on the door frame in one or more directions.</p> |
