Title: Door handle
Inventor: VAUGHT MICHAEL O
IPC: E05B17/00
Filed: 1993-01-06
Abstract: 57,016 ABSTRACT OF THE DISCLOSURE         A door handle for  breaking  a  vacuum  seal and opening a door in a single operation includes a handle and a latch cam, attached to the door, and a pin,  attached to a frame  of the  door.   The pin is engageable with a slot positioned on the latch cam.    The  slot  extends circum-ferentially around  at least  a portion of the diameter of the latch cam.  Due to the configuration  of the  slot, as the pin  travels within  the slot  to a  closed end of the slot, the pin progresses from a position farther  from the door to  a position closer to the door, causing the pin to exert pressure on a  second  surface  of  the  slot, which pulls the door toward the frame to close the door.  As the pin travels within the  slot away from the  closed end of the slot, the pin progresses from a position closer to the door to a position farther from the door,  causing a first surface of  the slot  to exert  pressure on the pin, which breaks the vacuum seal and unlatches the door  to open the door of a housing.

A first internal surface region of the T-shaped track opening is comparatively wider than a second internal surface region of the track opening. The second internal surface region merges with a third external region of the track opening. The improvement comprises a compressible, flexible, pliable member for cleaning, lubricating and maintenance of the T-shaped track opening. The pliable member is prefolded and united to provide a T-shape corresponding to the shape of the track opening. The pliable member comprises a T-shape to facilitate insertion of the pliable member into the track opening and to enable the pliable member to be in slidable engagement with the track opening. A control means adjustably shapes the pliable member when inserted within the track opening to cause the pliable member to compress and to substantially correspond to the T-shape of the track opening. The inserted pliable member is in slidable engagement with the track opening when subjected to compression through the control means, and when being slidably moved to allow the effects of corrosion to be reduced, and thereby, enhance a free running of the slides and boltropes under the loadings.
