Abstract

PURPOSE:To decrease ventilative resistance and always obtain a sufficient amount of air, by providing a means, whereby the direction of air throughout in every air blown space can be regulated in good controllability, to an air outlet. CONSTITUTION:An air outlet comprises a cylindrical panel 2 having an air blow port 1, fin 3 mounted to be combined as an integral unit in said panel 2, the first case 4 and the second case 5. If one end of the fin 3 is pressed by finger, the fin rotates to face its air guide path 33 to a direction of the air blow port 1, and the air blow port 1 is placed in an open condition from a closed condition. While if one end of the fin 3 is pressed by finger from the open condition and the fin 3 is rotated to a click position, the air blow port 1 is placed in a condition closed by disc parts 31, 32 of the fin 3. In this way, as the first case 4 can be turned with a click function integrally with the fin 3, two-dimentional regulation of the direction of air can be optionally performed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in air outlets installed on both sides of an instrument panel in a vehicle interior of an automobile or the like.

Conventionally, this type of air outlet was constructed by combining vertical and horizontal wind direction adjustment mechanisms.
With many air outlets, the wind direction can only be adjusted in two directions, and the range of adjustment is limited. In addition, if the wind direction is adjusted using a large number of fins, the ventilation resistance due to the sled fins will increase, and the swing function of the air outlet will also become narrower. The disadvantage is that it is not possible to obtain a sufficient amount of air at a temperature that is too low, resulting in the temperature becoming too high.

The present invention has been made in relation to these aspects, and provides an air outlet that allows for wide range adjustment of wind direction and opening/closing of the air outlet without increasing ventilation resistance. It provides:

Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings.

In the air out left according to the present invention, as shown in FIG. Attached fins 3. The first case 4 and the second case 5 are composed of η).

The fin 3 is integrally formed with upper and lower boss parts 34 and 35 so that two disk parts 31 and 32 are parallel to each other and an air guide path 33 is formed between them. , shafts 36 and 37 are formed protruding from the boss portions 34 and 35 so as to serve as the center of rotation of the fin 30. 1st
The case 4 has gear teeth 41 formed at one end of the cylindrical body, consisting of many peaks and valleys divided equally on the circumference, and the cylindrical body has a gear tooth 41 formed inside thereof. 3 fins shaft 36
, 37 for rotatable mounting.
, 43 are drilled. Note that a bushing 6 is provided in the hole 42.
The bush 6 and the hole 4 are fitted so that the shaft 36 of the fin 3 is attached to the hole 42 through the bush 6 and the hole 4 so that the bush 6 does not move relative to the first case 4.
I try to take the shape of 2. Furthermore, due to the tightening of the shaft 36 by the bush 6, a rotating load chamber is generated in which the fin 30 rotates. In addition, in the hole 43 portion, as shown in FIG. An rcv-shaped projection 47 (see FIG. 3) formed in the shaft 37 of the cutting fin 3 is inserted into the hole 43 and engaged with the square groove 38 (see FIG. 3). When the fin 3 is rotated from the state shown in FIG. 2(a), the bridge portion 46 is bent and the V-shaped groove of the shaft 37 is removed from the V-shaped protrusion 47 as shown in FIG. 2(b). become. Therefore, when the first case 4 is closed by the state fin 3 in FIG. 2(a), and when the case 4 in i@1 is opened by the state fin 3 in FIG. 2(b), the setting is n. By doing so, a click function for positioning the fins 3 when the fins 3 are closed is activated.

In addition, the second case 5 has two protrusions 51 formed on the circumference of one end of the cylindrical body, one at the top and one at the bottom. It is designed to mesh with the gear teeth 41, and its cylindrical body has a shape shown in FIG. 4 (a).
) As shown in FIG. 9, slits 52 are formed corresponding to each projection 51, and when the first turf 42 is rotated, the projections 51 are formed as shown in FIG. When the bridge portion 53 is bent, its protrusion 51 and gear teeth 41 (σ)
The occlusion is now outward. Therefore, it is possible to provide a click function when the first case 4 is rotated and positioned relative to the W, 20 case 5, and the first case 240 can be rotated and positioned to prevent it from wobbling. I have to. In addition, a net 55 is integrally formed at the other end of the cylindrical body of the second case 50 so as to protect the opening of the second case 50, so that even if a foreign object such as a coin enters the air outlet, the net 55 will not come in. Ensure that the nutrients do not fall inside the panel. Note that when the first case 4 and the second case 5 in which the fins 3 are incorporated are combined and installed in the panel 2, the first case 4 is inserted from the rear of the panel 2 into the panel 2 so that one end of the first case 4 is blown into the air. After inserting it until it hits the 10th step of the exit, insert the second
By inserting the case 4 of the case 4 and engaging the protrusions 54 provided at the top and bottom of the case 4 with the holes 21VC drilled at the top and bottom of the panel 2, respectively. I'm trying to keep it fixed. Furthermore, a springy claw 7 (for example, made of SK material) is attached to the rear of the air out left for fixing the L gain instrument panel when the attachment trap is attached. The claw 7 is attached by passing the tip of the U-shaped folded part of the claw 7 through the mesh of the mesh 55 and attaching it to the second
Of case 5! The claw 7 is fitted into the notch in the slit 53 from II, and is held by the folded portion between the second case 5 and the panel 2 to prevent the claw 7 from falling off.

Figure 5 shows the state in which each component of the air outlet shown in Figure 1 is integrated.
Air outlet 1 depending on the 0 disc part? This shows the state when it is blocked. As shown in FIG. 5, a slight gap ga' is provided between the fin 3 and the first case 4 in order to facilitate the rotation of the fin 30, but the air outlet l by the fin 3 is In order to suppress the wind from the gap g as much as possible when the gap g is closed and to prevent the generation of beeping noise, the inlet part a'j of the gap on the first case 4 side is formed in a convex shape, and the inlet part of the gap g is formed in a convex shape. The flow of the coming wind is directed inward.

The arrow in the figure indicates the wind flow at that time. Also,
The air is blown out to the air outlet 1 through the gap gχ, and the air outlet 1 is provided with a constant f'L in the first case 4.
There is a stepped part that locks the brim! This will prevent the generation of beeping noise due to the disturbance caused by the noise.

In the air outlet according to the present invention configured as described above, when one end of the fin 3 is pressed with a finger from the closed state of the air outlet 1, the fin 3 rotates and the air guide path 33 closes the air outlet 1. It will be in the open state when facing the direction of. Also, F/3
When the fin 3 is rotated from the open state to the click position # by pressing one end with a finger, the 74730 disc part 31
, 32, the air outlet l is in a closed state f'.

At that time, as shown in FIG.
1 and 32 are provided with hot stamps M as marks for opening and closing the air out left by pressing with the fingers of the fins 3. Also, when opened, the fin 30
By changing the amount of rotation, it becomes possible to appropriately adjust the wind direction in one direction, such as left or right. Furthermore, since the air outlet V according to the present invention is integrated with the fin 3 and can be rotated by a click function of the first case 4, when the fin 3 is opened, the fin 3χ You can freely pinch it with your fingers [36
It becomes possible to rotate it by 0 degrees, and with this mechanism, it becomes possible to perform two-dimensional wind direction adjustment.

Therefore, in the air outlet according to the present invention, the air outlet l can be opened and closed in one click, and the air direction can be adjusted over the entire air outlet space by appropriately combining 30 rotations and rotations of the fins. It has the advantage that it can be performed easily. In addition, since the wind direction is adjusted by the companion fin 3, which is made up of at least two pieces, there is little ventilation resistance, and there is no possibility that the air outlet 1 will be narrowed when adjusting the wind direction. It has the advantage of always being able to obtain sufficient air volume.
