Position adjusting mechanism of a soft-closing device for a sliding door

摘要

A position adjusting mechanism of a soft-closing device for a sliding door has a bracket with a mounting panel and at least one positioning rack, a cover panel mounted on the bracket, and a positioning hook, a torsion spring and a driving element pivotally mounted on the cover panel. At least one first fastener is mounted through the cover panel and the mounting panel and is fastened to a door track. The bracket can slide relative to the cover panel to allow the positioning hook to selectively engage in different engaging recesses of a corresponding positioning rack. Thus, moving distance of the bracket and a door panel suspended from the bracket can be estimated. Accordingly, positions of the bracket and the door panel on the door track can be adjusted to allow the door panel to close a doorway completely.

主权项

1. A position adjusting mechanism of a soft-closing device for a sliding door comprising:
a bracket having two opposite ends and a mounting panel, the mounting panel formed on one of the ends of the bracket and having
a lower surface;two opposite side edges;at least one adjusting hole formed through the mounting panel, each of the at least one adjusting hole of the mounting panel being elongated and extending parallel to the side edges of the mounting panel;at least one sliding hole formed through the mounting panel, each of the at least one sliding hole being elongated and extending parallel to the side edges of the mounting panel; andat least one positioning rack disposed on the lower surface of the mounting panel, each of the at least one positioning rack being toothed, disposed along a corresponding one of the side edges of the mounting panel and having multiple engaging recesses; a cover panel mounted below the mounting panel and having
an inner surface facing the lower surface of the mounting panel; anda through hole formed through the cover panel; a positioning hook pivotally mounted on the inner surface of the cover panel and having
a driven protrusion protruding from a side edge of the positioning hook; andan engaging protrusion protruding from the side edge of the positioning hook and toward a corresponding one of the at least one positioning rack, and selectively engaging in one of the engaging recesses of the corresponding positioning rack; a torsion spring mounted on the inner surface of the cover panel and having two ends, one of the ends of the torsion spring being stationary, the other end of the torsion spring abutting the positioning hook and pushing the positioning hook to rotate, such that the engaging protrusion of the positioning hook engages in one of the engaging recesses of the corresponding positioning rack; a driving element pivotally mounted on the inner surface of the cover panel, disposed beside the driven protrusion of the positioning hook, and corresponding in position to the through hole of the cover panel, the driving element having a driving protrusion protruding from a side edge of the driving element and abutting against the driven protrusion of the positioning hook, the driving element configured to selectively disengage the engaging protrusion from the engaging recess; at least one sliding rod securely attached to the cover panel, each of the at least one sliding rod mounted through the at least one sliding hole of the mounting panel and connected with a washer; and at least one first fastener mounted through the cover panel and the at least one adjusting hole of the mounting panel of the bracket for non-slidably attaching the cover panel to a track.
