Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rotary operation knob for opening and closing an air outlet.

(Prior Art) Conventionally, an air outlet device shown in FIGS. 5 and 6 is known.

On both sides of the retainer 10 forming the air outlet 1 and the air passage 2, for example, engaging claws 12 for attaching to an instrument panel of an automobile, through holes for respectively supporting an opening / closing member 14 and a barrel 16 described later. 18 and 20 are provided.

The barrel 16 is rotatably supported by the retainer 10 in a vertically rotatable manner, and a plurality of plate-shaped blades (not shown) are rotatably supported in the barrel 16 by a lever 24 so as to be rotatable in the left and right directions. It is possible to operate. Barrel 16 retainer 10
When mounted on the intermediate member 30 having a cylindrical portion 26 and a square portion 28 on the shaft (not shown) on the left side of the barrel 16 in the drawing,
After inserting the disk-shaped rotary operation knob 32 into the cylindrical portion 26 of the intermediate member 30, the square-shaped portion 28 of the intermediate member 30 is inserted.
Is fitted into the rectangular through hole 20 on the left side of the retainer 10 in the figure. By doing this, the barrel 16 is
This makes it possible to rotate with respect to 10 and the intermediate member 30, and the barrel 16 and the rotation operation knob 32 do not rotate simultaneously on the other side.

The outer peripheral portion 33 of the rotating operation knob 32 has a gear shape, and is easy to operate.

The opening / closing member 14 is supported by the retainer 10 as described above.
It is possible to rotate around 34. Further, the opening / closing member 14 is provided with a fan-shaped gear 36 having a central angle of 90 °, and meshes with a gear-shaped outer peripheral portion 33 of the rotation operation knob 32 in a state of being assembled to the retainer 10 to rotate the rotation operation knob 32. As a result, the opening / closing member 14 can be rotated.

In this air outlet device, the air passage 2 is open when the opening / closing member 14 is in the rotating position as shown in FIG. 5, and is opened and closed by rotating the rotating operation knob 32 in the direction of arrow A. The member 14 rotates in the direction of arrow B, and closes the air passage 2 at the position rotated by 90 °.

Further, since the diameter of the rotation operation knob 32 and the gear 36 and the pitch of the teeth are the same, they are rotated by exactly the same angle.

The rotation operation knob 32 is displayed, for example, on the inner surface 38 of the side wall of the retainer 10 as shown in FIG. 6 with the plate 40 showing that the air passage 2 is open and the plate 42 showing that the air passage 2 is closed. It was done by pasting. As a result, it has been shown to which way the turning operation knob 32 is turned, what the opening / closing member 14 is, that is, what the air passage 2 is. Other similar plates 4
0, 42 to the upper and lower inner surfaces 44, 46 of retainer 10 or retainer 1
Some were stuck on the front 48, 50 of 0.

(Problems to be solved by the invention) However, in the above display, it is not possible to know just by looking at the position of the opening / closing member 14, that is, whether the air passage is closed or open. was there.

There is a technique disclosed in Japanese Utility Model Laid-Open No. 61-186050 as a means for solving this, but in order to confirm the open / closed state of the air passage, first check the position of the operation knob, and then next to the operation knob. It is necessary to make a two-stage judgment to judge whether the displayed contents mean opening or closing.

Further, in the former prior art, when the retainer 10 is provided with a three-dimensional pattern such as a texture for improving the design, the flat surface portion is used to attach the plates 40 and 42 as described above or to print the display pattern. However, it has been difficult to form a small flat portion on a large part such as the retainer 10 at an accurate position. Further, in the automobile air outlet device, the front surface of the retainer 10 may be softened to improve safety, and in this case, it was difficult to attach the plates 40 and 42 or print the display pattern. Incidentally, these problems also occur in the latter conventional technique disclosed in Japanese Utility Model Laid-Open No. 61-186050.

The present invention aims to solve the above problems.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an opening / closing member that is provided in the inner part of the opening of the air outlet device to open or close the air passage, and the opening / closing member. In an air outlet device having a substantially fan-shaped or substantially disc-shaped rotation operation knob for operating the air passage through a predetermined coupling mechanism, an open state of an air passage by an opening / closing member is provided on an outer peripheral portion of the rotation operation knob. , And a second display portion indicating the closed state of the air passage at a position where the central angle is about 90 ° apart from the first display portion.

(Operation) Therefore, according to the above configuration, it is possible to know at a glance which one of the first display portion and the second display portion is displayed, that is, the open / closed state of the air passage, simply by looking at the rotary operation knob.

Further, since the rotation operation knob is a relatively small part, the deviation of the molding position of the flat surface portion or the like for forming the display portion causes almost no problem.

Further, since the rotary operation knob has a high rigidity in terms of its function, it is not so soft that the plate cannot be attached or the display pattern cannot be printed.

(Example) Hereinafter, a specific example of the present invention will be described with reference to the drawings.

1 to 3 show a first embodiment of the present invention, in which parts corresponding to those in FIGS. 5 and 6 are designated by reference numerals.
A description is omitted by adding 100.

A feature of the present invention is that the outer peripheral portion 133 of the rotary operation knob 132 has a first opening indicating an open state of an air passage (not shown).
The display unit (plate 140 in the drawing) and the second display unit (plate 142 in the drawing) indicating the closed state are provided at a position where the central angle is about 90 ° apart from the first display unit. .

In the first embodiment, flat portions are provided at two positions separated by 90 ° at the central angle of the gear-shaped outer peripheral portion 133 of the disc-shaped rotary operation knob 132, and the air passage is open there. And a plate 142 showing that the air passage is closed. In FIG. 1, the plate 140 showing that the air passage is open faces the front of the air outlet 101, and the plate 14 showing that the air passage is closed is shown.
At a glance, you can see that the air passage is open because 2 is not visible.

FIG. 4 shows a second embodiment of the present invention, in which parts corresponding to those in FIG.

In the second embodiment, a white circle is drawn on the plate 240 showing the state where the air passage is open, and a black circle is drawn on the plate 242 showing the state where the air passage is closed. The pattern or symbol drawn on the display portion as in this embodiment may be any as long as it can indicate the open / closed state of the air passage.

The present invention is not limited to the above embodiment,
For example, the display may be any pattern, symbol, etc. as described above, and the means for providing the display is not limited to the one to which the plate is attached, and may be any other such as printing.

Further, the rotation operation knob does not necessarily have to be a disc shape,
It may be fan-shaped, or the disk-shaped or fan-shaped outer peripheral portion may be formed by a straight line instead of an arc.

Further, the means for transmitting the operation of the rotation operation knob to the opening / closing member may use a link mechanism instead of the meshing of gears.

(Effects of the Invention) As is apparent from the above description, according to the present invention, it is possible to determine whether the air passage is opened or closed simply by checking which of the first display portion and the second display portion is displayed. You can judge immediately. Further, the respective display portions can be provided at accurate positions regardless of the configuration (material, presence or absence of grain, etc.) of the member (retainer or the like) forming the air outlet.
