Method And Device For Evaluating Door Closing Performance

摘要

A device and method are disclosed for evaluating closing performance of a door in which the door engages an engagement element included in the device which is detachably mounted to fixed structure adjacent the door and which is moved by an opening movement of the door. An elastic element such as a spring is deflected by the motion of the engagement element to generate elastic potential energy which is detected and shown by a detector/display so that the point of release of the door is determined when the potential energy reaches that corresponding to a predetermined minimum mechanical energy level. The door is then swung in a closing direction by the potential energy stored in the elastic element and it can be immediately determined if the door closure performance is met by the door becoming fully closed.

主权项

1. A method for determining if a predetermined minimum level of mechanical energy will completely close a hinged door comprising:
disposing an engagement element so as to be contacted by said door as said door is swung out in an opening direction under the control of an inspector, said engagement element continued to be moved thereafter by continuing the movement of said door in an opening direction; creating a corresponding increasing potential energy as said movement of said engagement element proceeds after said door contacts said engagement element by generating an elastic resistance to said movement to create elastic potential energy which acts on said door through said engagement element upon release of said door to move said door towards a closed position; determining and displaying the level of elastic potential energy created as said door is swung open against the elastic resistance thereto to allow an inspector to observe when said predetermined minimum level of mechanical energy corresponding to said elastic potential energy has been reached, and thereafter releasing said door to allow said door to be swung towards a closed position solely by the effect thereon of said elastic potential energy; and observing if said door is thereafter completely closed or not completely closed thereby determining if said predetermined mechanical minimum energy has or has not achieved complete closure of said door.
