Automatic homing slide track device

Abstract

The present invention provides an automatic homing slide track device which comprises: a bottom track and a slide track provided with a push rod protruding from one side; a control base comprising a spring groove and an actuating slide way with a slot defined at the front end; a slide/swing unit with a slide member and a swing member joining each other wherein the swing member is provided with a clasper at the front end and an actuating part at the rear end on which there is at least a second actuating groove designed at the front part; a flexible member allowing its front and rear ends to be fixed on the slide member' and the spring groove's rear ends, respectively. The abovementioned push rod can enter the second actuating groove of the swing member and slide and deflect the swing member.

What is claimed is: 
     
         1 . An automatic homing slide track device comprising:
 A bottom track with a bottom track space;   A slide track moving in said bottom track space of said bottom track and comprising a push rod protruding from one side of said slide track;   A control base fixed on said bottom track and comprising a spring groove at the rear part and an actuating slide way at the front part on which there is a slot defined at the front end;   A slide/swing unit installed in an actuating slide way of said control base and comprising a slide member and a swing member joining each other and sliding synchronously wherein said swing member is installed at the front end of said slide member and provided with (a) a clasper at the front part and (b) an actuating part at the rear part on which there is at least a second actuating groove at the front part;   A flexible member installed in said spring groove of said control base and allowing its front and read ends to be fixed on said slide member's and said spring groove's rear ends, respectively;   In the abovementioned structure, said push rod enters said second actuating groove of said swing member to slide and deflect said swing member so that said deflected swing member makes said clasper withheld in said slot.   
     
     
         2 . The automatic homing slide track device according to  claim 1  wherein said control base comprises a main base plate and said spring groove is one groove enclosed by said main base plate and two lateral end sheets of said main base plate and is provided with a fastening part fixing said flexible member at the rear end. 
     
     
         3 . The automatic homing slide track device according to  claim 2  wherein said actuating slide way is a double U-shaped groove enclosed by said main base plate, said two end sheets and an extender. 
     
     
         4 . The automatic homing slide track device according to  claim 1  wherein said actuating slide way is provided with a baffle at the rear end as a fallback of said slide/swing unit during a reverse movement. 
     
     
         5 . The automatic homing slide track device according to  claim 2  wherein said main base plate is provided with a through window which is opposite to said actuating slide way. 
     
     
         6 . The automatic homing slide track device according to  claim 5  wherein said through window's front end extends backward to develop a stopper. 
     
     
         7 . The automatic homing slide track device according to  claim 1  wherein said slide member is provided with a positioning part at the rear end which is used to fix said flexible member. 
     
     
         8 . The automatic homing slide track device according to  claim 1  wherein said swing member has an end part at the front part which is used to develop said clasper and a slanted guide plane, front low and back high. 
     
     
         9 . The automatic homing slide track device according to  claim 1  wherein said swing member has a separator, which is located at the front end of said second actuating groove and further comprises a first actuating groove at the front part, and an actuating channel among said second actuating groove, said first actuating groove and said separator. 
     
     
         10 . The automatic homing slide track device according to  claim 9  wherein said actuating channel has an offset design in a movement path at which said slide member joins said swing member.
