Air-conditioning vent vane adjusting device

Abstract

An air-conditioning vent vane adjusting device includes a board for driving a vane to rotate, a push-button slidably installed on a panel, and a connecting plate fixedly attached to the board. A fixed plate is coupled to the push-button and is moved together with the push-button, and the fixed plate has a guide notch tilted with respect to the longitudinal direction of the board. The board has a lug accommodated in the guide notch and capable of sliding in the guide notch. With the tilted guide notch and the lug, the board can be moved reciprocally to overcome the problems of requiring a large operating force of the push-button of the tight assembly of the conventional board and connecting plate and the difficulty of opening and closing a vane.

Claims

1. An air-conditioning vent vane adjusting device, comprising a board for making a vane rotate, a push-button installed on a panel, and a fixed plate fixed to the push-button so that the fixed plate moves with the push-button, wherein the fixed plate includes a guide notch defined therethrough and tilted with respect to a longitudinal direction of the board; a connecting plate has a lug accommodated in the guide notch and capable of sliding in the guide notch, wherein one end of the guide notch is open-ended, and the guide notch is defined on a lower edge of the fixed plate; the connecting plate is immovably and non-rotatably fixed on the board, and the connecting plate extends a sliding distance of the lug in the guide notch; wherein when opening an air-conditioning vent for ventilation, the push-button is pushed on the panel so that the push-button slides to make the fixed plate connected to the push-button move together, the lug slides in the guide notch so that the connecting plate makes the board move, the board pushes a connecting shaft on the vane so that both ends of the vane rotate in a mounting hole of a frame to open the vane.

2. The air-conditioning vent vane adjusting device of claim 1, wherein the guide notch is tilted with respect to the longitudinal direction of the board in an angle of 40-50 degrees.

DETAILED DESCRIPTION OF THE INVENTION

(6) The technical characteristics and objectives of the present invention can be further understood by the following detailed description of preferred embodiments and related drawings.

(7) With reference to FIGS. 1 to 5 for the structure of an air-conditioning vent used by an air-conditioning vent vane adjusting device in accordance with a preferred embodiment of the present invention, the air-conditioning vent comprises: a panel 1, including a grating 11, and a slide 12 disposed on the panel 1; a frame 2, installed on a wall, and disposed on an inner side of the panel 1, and provided as a connecting base for connecting components such as the panel 1, vanes 3, and a board 4, wherein the frame comes with a large frame structure; a plurality of vanes 3, with both ends rotatably mounted onto two opposite sides of the frame, and each vane having a connecting shaft 31 disposed on the same end of the vanes; and a board 4, corresponsive to the connecting shaft 31 for fixing and coupling the connecting shaft 31 therethrough.

(8) In FIGS. 1 to 5, the air-conditioning vent vane adjusting device of this preferred embodiment further comprises: a push-button 5, installed on the panel 1, and having a lower portion passing through a slide formed on the panel 1 and disposed on an inner side of the panel, and the push-button 5 being capable of sliding in a longitudinal direction along the slide on the panel; a fixed plate 6, installed parallel to a side of the frame and disposed on an inner side of the panel, and coupled to the bottom of the push-button 5, such that the fixed plate 6 can be moved reciprocally by the sliding of the push-button, wherein the fixed plate includes a guide notch 61 tilted with respect to the longitudinal direction of the board, and an included angle of 45 degrees is defined between the longitudinal directions of the guide notch 61 and the board of this preferred embodiment, and the guide notch 61 is defined at a lower edge of the fixed plate; and a connecting plate 7, fixed and coupled to the diving board 4, and having a lug 71 disposed on the connecting plate 7 and accommodated in the guide notch 61, and capable of sliding in the guide notch 61 along the longitudinal direction of the guide notch 61.

(9) The air-conditioning vent vane adjusting device is operated according to the following principle: To open the vanes for ventilation, the push-button is pushed on the panel, so that the push-button slides in the slide to drive the fixed plate connected to the push-button to move together. The lug slides in the guide notch, so that the connecting plate drives the board to move. The board pushes the connecting shaft on the vane, so that both ends of the vane rotate in the mounting hole of the frame to open the vane as shown in FIG. 4.

(10) To close the vanes, the push-button is operated reversely.

(11) To adjust the size of the opening of the air-conditioning vent, the push-button is pushed to a corresponding position.
