Sliding track coupling structure for sliding doors
A sliding track for sliding doors includes a sliding door track and a glass fixed panel track which have an inverted U-shape cross section with an opening facing downward. The sliding door track has a left and a right inner wall that have a pair of guiding tracks formed thereon to allow a plurality pairs of rollers which are hinged on a hanging track which is fastened to a sliding door on a lower side to roll thereon in a straddle manner. The sliding door track further has a pair of first wedge troughs on the upper left and upper right corners, and a pair of second wedge troughs on a lower side. The first and second wedge troughs are coupled with the glass fixed panel track. The sliding door track and the glass fixed panel track may also be coupled with an ornamental plate on the top. The glass fixed panel track may further be coupled with a sealing plate on the bottom.
1. A sliding track for sliding doors, comprising:
a sliding door track which has an inverted U-shape cross section with an opening facing downwards and a pair of guiding tracks formed on a left inner wall surface and a right inner wall surface to allow a plurality of rollers rolling thereon in a straddle manner, the rollers being hinged transversely on a hanging track which is fastened to a sliding door on a lower side, the sliding door track further having a pair of identically shaped first wedge troughs on an upper left corner and an upper right corner, and a pair of second wedge troughs on a lower side; and
a glass fixed panel track which has an inverted U-shape cross section with an opening facing downwards to form a clipping trough to clip a glass fixed panel, and a latch portion corresponding to the first wedge trough of the sliding door track and a hook beneath the latch portion, the latch portion and the hook being engaged with the first wedge trough and the second wedge trough;
wherein the clipping trough has inner walls which have a pair of indented latch troughs formed thereon, the sliding track further having a sealing plate formed in an inverted U-shape that has an opening facing upwards and a left side panel and a right side panel on two sides, the left side panel and the right side panel having respectively a bulging latch portion on an outer side wall thereof corresponding to and engaged with the latch troughs of the clipping trough to hold the sealing plate on the bottom of the clipping trough.
