[0033] As described above, the present invention’s ‘rotate bar non-rotating knob’ (200) includes a knob (210), an inner link (220), an outer link (230), and a rotate bar (240).
[0034] The knob (210) controls the airflow direction of the air vent by allowing the user to grip it and adjust the angle of the vane, and has the shape of a plate with a certain thickness and includes a knob touch rib (211) and a protrusion (212).
[0035] The above protrusion (212) is provided in a protruding state on one side of the upper surface of the knob (210), thereby having the effect of securing a side area that can be organically combined with the inner link (220), etc. described later, and also having the effect of reinforcing the knob (210).
[0036] The above knob-touch ribs (211) are provided with two protruding longitudinally while forming a constant spacing in the transverse direction on one side of the knob (210) and the protrusion (212), thereby having the effect of restricting the operating trajectory of the rotate bar (240), and a first through hole (H1) is formed through the lower surface so that the inner link (220) can be connected to rotate around the knob pin (P1) that passes through the first through hole (H1).
[0037] It goes without saying that by installing the upper head (221) of the inner link (220) described later between the knob-touch ribs (211) as described above, it is possible to have the function and effect of preventing left and right movement of the inner link (220).
[0038] The inner link (220) is rotatably coupled to the knob (210) and is rotatably coupled around the knob pin (P1) that penetrates the first through hole (H1) while inserted between two knob touch ribs (211), and includes an upper head (221), a lower head (222), and a connecting bar (223).
[0039] The upper head (221) is cylindrical in shape and is installed in a transverse direction relative to the knob (210), with a second through hole (H2) penetrating through the center. With the upper head (221) installed between two knob-touch ribs (211), the knob pin (P1) is fastened by penetrating the first through hole (H1) formed in the knob-touch rib (211) and the second through hole (H2) of the upper head (221), thereby allowing the upper head (221) to rotate around the knob pin (P1).

[0045] Accordingly, the outer link (230) is coupled so as to be rotatable around a link pin (P2) that penetrates both the third through hole (H3) provided in the lower head (222) of the inner link (220) inserted into the concave groove (232) and the fourth through hole (H4) formed on the lower side of the outer link (230).
[0046] The above-mentioned fifth through hole (H5) is provided in a shape that penetrates the upper side of the outer link (230).
[0047] Additionally, the outer link (230) is inserted into the guide groove (241) of the rotate bar (240) and is coupled so as to be rotatable around the ‘rotate bar pin’ (P3) which penetrates both the sixth through hole (H6) formed on the upper side of the rotate bar (240) and the fifth through hole (H5) of the outer link (230).
[0048] The above outer link stopper (231) is provided in a protruding state on the upper part of the outer link (230), and when the outer link (230) rotates, it contacts the upper surface of the guide groove (241) of the low rate bar (240) to limit the range of rotation.
[0049] That is, the inner link (220), outer link (230), and rotate bar (240) are assembled with pins to transmit the rotational movement of the knob (210) to the rotate bar (240) and to regulate the directional movement of the rotate bar (240).
[0050] The rotate bar (240) is configured to adjust the wind direction to the left and right by rotating the vertical vane (W), and has a guide groove (241) formed on one side and a sixth through hole (H6) provided on the upper side.
[0051] The guide groove (241) is provided in a recessed shape on one side of the rotate bar (240) so that an outer link (230) is inserted therein, and the outer link (230) inserted into the guide groove (241) is coupled so as to be rotatable around a ‘rotate bar pin’ (P3) that passes through both the sixth through hole (H6) formed in the rotate bar (240) and the fifth through hole (H5) provided on the upper side of the outer link (230).
[0052] The present invention, as described above, has a combination of effects: reducing airflow loss by minimizing unnecessary shapes in the vanes through a non-rotating rotating bar structure; improving quality by optimizing the horizontal vane shape through non-rotating rotating bar when the knob is operated up and down; improving the problem of the rotating bar coming off through a pin assembly structure; and improving the appearance image by minimizing the exposure of unnecessary shapes of the knob when the knob is operated upward.
