Abstract
A guiding-wire controlling rod device for chair adjustment is pivotally attached inside a housing by a rotation plate of a pivoting rod. The rotation plate has two sides each with a guiding-wire retaining notch and has multiple abutting flat surfaces formed at a front end of the rotation plate to abut with a resilient sheet to position the rotation plate at different angles. Moreover, a rear end of a controlling rod of the pivoting rod has a pivotal hole to pivotally engage with another controlling rod to drive other guiding-wires. Thereby, the controlling rods are aligned and control respectively multiple guiding-wires for different functions.
Claims9
A guiding-wire controlling rod device for chair adjustment comprising:
- a housing;
- a pivoting rod with a rotation plate having two sides, with the pivoting rod pivotally attached inside the housing for pulling two guiding-wires, with two wire-retaining notches defined on the two sides respectively, with a controlling rod extending from the rotation plate;
- and
- a triggering rod controlling at least one more guiding-wire, with the triggering rod pivotally connected to the controlling rod, wherein the rotation plate has a front end and multiple abutting flat surfaces formed on the front end;
- wherein the controlling rod has a wire-guiding groove and a pivot hole substantially perpendicular to the pivot hole of the rotation plate;
- wherein the housing includes an upper case and a lower case correspondingly combined;
- wherein the lower case has a front end and a stop formed on the front end of the lower case, wherein the stop has two wire tubes aligned with the wire-retaining notches on the rotation plate;
- wherein a resilient arc sheet is mounted on the stop to abut one of the multiple abutting flat surfaces;
- and wherein the triggering rod has a pin hole and has a wire-retaining notch aligning with the wire-guiding groove.
