  • the present invention of an assembled automatic homing slide track device allows the push rod 22 of the slide track 20 to enter the second actuating groove 426 of the swing member 42 and slide and swing the slide/swing unit 40 .
  • FIGS. 5 An and 5 B which illustrate the push rod 22 of the slide track 20 moving forward with a pulled locker drives the swing member 42 (slide/swing unit 40 ) onward and further pulls the flexible member 50 due to the slide member 41 .
  • the swing member 42 under application of a pull on the slide track 20 and the push rod 22 will deflects because the end part 422 at the front end of the swing member 42 is not against the actuating slide way 34 ; the deflected swing member 42 under the pull applied on the flexible member 50 allows the clasper 423 of the swing member 42 to be withheld in the slot 345 and stays in a steady state temporarily.
  • the push rod 22 moving forward departs from the second actuating groove 426 , continuing its movement along the actuating channel 427 and totally leaving the swing member 42 and the control base 30 so that the slide track 20 (locker) is driven onward until a completely stretchable status.
  • the slide track 20 of the locker moving in a reverse direction allows the push rod 22 to pass the actuating channel 427 of the swing member 42 , enter the second actuating groove 426 , and continuously drive the actuating part 428 so that the swing member 42 separates itself from deflection and the clasper 423 of the swing member 42 is not withheld by the slot 345 ; the slide/swing unit 40 completes automatic homing under a pull of the flexible member 50 and the slide member 41 finally arrives and stops at the baffle 342 to finish an automatic homing operation with the locker pushed backward.
  • FIG. 6 which illustrates a troubleshooting procedure for the present invention.
  • the push rod 22 of the slide track 20 suffering from vibration, collision, or error in operation during opening or closing a locker might immediately deflect from the actuating channel 427 and allows the slide/swing unit 40 pulled by the flexible member 50 to move back in a very short time.
  • the fact that the push rod 22 which keeps at the front end of the non-deflected swing member 42 neither enters the actuating channel 427 nor continues controlling the swing member 42 (slide/swing unit 40 ) is considered as failure of automatic homing.
  • the locker should be pushed in order to make the push rod 22 along the slanted guide plane 422 a force the swing member 42 .
  • this mechanism to press and sink the swing member 42 based on the through window 343 allows the push rod 22 to enter the actuating channel 427 until the second actuating groove 426 and resume the push rod 22 in a proper position.
  • the stopper 344 at the front end of the through window 343 can resume a proper position and status of the sunken swing member 42 by thrusting the swing member 42 .
  • the present invention of an automatic homing slide track device features a compact overall structure for correct stable operations, components simply and quickly assembled or disassembled, reduced manufacture, assembly and maintenance costs, and positive economic benefits.
