Patent ID: 8714671

Claim:
An automatic homing and track buffering device which for integration into a cabinet or a locker drawer, comprising: a buffer base comprising a main base body with a buffer groove space and a flexible groove space prepared at both sides: said main base body has (a) a slide margin extending forward along a lateral margin, (b) a slide terminal developed in the front of said slide margin, and (c) a revolving-oriented groove is provided with a resistive groove wall inward beveled and concave which is developed to be a curved or straight concave wall, which revolving-oriented groove is obliquely opposite to a revolving-resistant member, a beveled resisting plane is located in the front of said main base body and opposite to said revolving-oriented groove and said beveled resisting plane as well as said revolving-resistant member are separated by a retracted space which is contrary to said revolving-oriented groove, (d) said revolving-resistant member, which is located at said main base body's front end and opposite to said slide terminal and has a straight slip resisting wall being opposite to the slide margin and continuously linking a curved revolving-resistant wall ahead; a buffer member held in said buffer groove space, which buffer groove space has a locating seat designed at the rear end and used to position said buffer member; a flexible member held in said flexible groove space, which flexible groove space has a locating seat designed at the rear end and used to position said flexible member; a swing member jointing and linking the buffer member's and the flexible member's front ends separately and provided with a push arm which is opposite to said slide margin: (a) said push arm has a draw arm at the front end for development of an operating space between said push arm and said draw arm; (b) said draw arm is provided with a first slider on the external side as well as a second slider on the internal side at the bottom for development of a slide groove in between; (c) said slide groove is formed on the slide margin; (d) said second slider has a curved part at the rear end; whereby, when a cabinet or a locker drawer body is drawn out, the second slider of the swing member which arrives at the slide terminal will be deflected along the slip resisting wall and the revolving-resistant wall on the revolving-resistant member under effect of both a forward tensile force of a cabinet or a locker drawer and a lateral tensile force of the flexible member, the first slider of the deflected swing member enters into the revolving-oriented groove, the second slider of the swing member under effect of a lateral tensile force continuously applied by the flexible member is restrained and positioned at the beveled resisting plane and the revolving-resistant wall of the revolving-resistant member; the first slider contacts the resistive groove wall and temporarily positions the swing member.
