Patent ID: 8083269

Claim:
An apparatus for effecting an initial, predetermined translation of a closed sliding door, said apparatus being adapted for initially pushing away said closed sliding door from a fixed door jamb toward an open position, said apparatus comprising a hand gripping-operating unit, wherein are structurally and functionally combined the following: means for gripping; base means for mounting components of said hand gripping-operating unit, the latter means being vertically oriented and to which said means for gripping is pivotally connected; said base means for mounting the components of said hand gripping-operating unit basically comprising an elongated body and a positioning-attachment element connected to said elongated body; means for operating, actuated by said means for gripping; said means for gripping including a gripper, from which, at one of its vertical extremity, a lever, integral with said gripper, is horizontally extending; said means for operating comprising an upper and a lower spring guide block, said upper spring guide block incorporating two intercommunicating, longitudinally opposed channels: an upper, top facing channel, closed at both ends, and a lower, bottom facing channel, open at both ends; a helical compression spring disposed into said lower, bottom facing channel; a pushing pin provided with a tooth extension, laterally projecting, said tooth extension, after traversing said upper, top facing channel, penetrates into said lower, bottom facing channel, behind one end of said helical compression spring; said pushing pin incorporating as well lateral shoulders that contact an upper external surface situated around and along said upper, top facing channel and are able to slide together with said pushing pin on the latter; whereby said pushing pin is used for an initial detaching of said closed sliding door from said fixed door jamb, while said tooth extension, which projects laterally from said pushing pin, operates against said helical compression spring to retract said pushing pin after the initial detachment ceases; and when said apparatus for effecting an initial, predetermined translation of a closed sliding door will be used for the other side of said door, said spring guide block will be rotated at 180 degrees, so said upper, top facing channel and said lower, bottom facing channel interchange their positions.
