Description

[Detailed Description of the Invention] The present invention relates to an improvement in an air conditioner that is attached to an opening on the inside of a duct in a vehicle, particularly an instrument panel of an automobile.

Conventional air conditioners of this type have a fixed frame with movable or fixed blades arranged horizontally, vertically, or vertically and horizontally, a so-called ventilation grille, attached to the surface of an instrument panel, etc. is generally adopted. However, since the ventilation grill of this type has a stationary structure, the wind direction (for example, the blowing direction) is determined, and although it is possible to obtain a certain range with movable blades, it is not sufficient. Without,
The desired wind direction could not be obtained satisfactorily for the driver and fellow passengers. As a solution to the above-mentioned conventional drawbacks, for example,
As seen in Japanese Patent No. 118107, a curved cylindrical ventilation grille has been devised so that it can be moved in a drawer manner relative to the opening of the duct, that is, the instrument panel. However, with this type of device, the entire ventilation grille must be grasped each time to pull it out, which is a very troublesome operation. Since the opening of the duct is closed by the ventilation grill, the air circulation function is completely eliminated, which is not desirable.

The purpose of the present invention is to take into account the above-mentioned drawbacks of the conventional technology.
The movable inner case is connected to the opening of the duct and is attached to the duct so that it can be popped out and stored, and the popping out operation can be performed with a single touch, and even when the duct is in the stored state, there is no connection between the duct and the passenger compartment. To provide an air conditioner for a vehicle that can maintain air circulation without blocking it.

Hereinafter, the illustrated embodiment embodying the present invention will be described in detail. As shown in FIG. It is integrated into the instrument panel P and communicates with an opening D' of a duct D disposed inside the vehicle interior.

Fixed frame 2 constituting the board of the air conditioner 1
As shown in FIGS. 2 and 3, the frame piece 3 is molded from synthetic resin and consists of a rectangular frame piece 3 and a side piece 4 hanging three times around the lower surface of the frame piece 3. is placed on the periphery of the opening D' of the instrument panel P, and is fixedly attached with each side piece 4 facing into the opening D'.

The movable inner case 5 constituting the main body of the air conditioner 1 is also molded from synthetic resin or the like, and as shown in FIGS. 2 and 3, it is formed into a substantially box shape with the upper and lower surfaces open. It is fitted into the opening of the fixed frame 2 and is tiltably supported by support pins 6, 6 at both front sides (both right end sides in FIG. 3) with respect to the fixed frame 2. As a result, the movable inner case 5 is fitted to the fixed frame 2 so as to be tiltable in the direction of protruding from the surface of the fixed frame 2 and in the direction of being accommodated in the opening of the fixed frame 2, using the support pins 6, 6 as fulcrums. The state will be as follows.

Flat blades 7 to 7, 8 to 8 are arranged at predetermined intervals in the vertical and horizontal directions in the opening at the substantially upper part of the movable inner case 5, and among these blades, the vertical blades 7 to 7 are arranged at predetermined intervals. It has a movable structure so that it can be rotated within a range of
It is movably operated by. In addition, the movable inner case 5
The rear side plate (the side plate opposite to the support pins 6, 6, the left side in FIG. 3) is connected to the support pins 6, 6.
Furthermore, the lower end of one of the left and right side plates (the left side in FIG. 2) has the same arcuate surface as the arc of the rear side plate, and a desired tooth-shaped portion 10 is continuously formed. ing. however,
The toothed portion 10 protrudes from the front portion of the movable inner case 5, as shown in FIG.

Below the toothed part 10 of the movable inner case 5, as shown in FIG. A winding drum 14 is integrally formed with the driving gear 11 and the support shaft 12 to wind up a biasing means 13 such as a coiled spring, which will be described later. 13 is wound around a winding drum 14, one end of which is attached to the support shaft 12, and the other end is attached to a branch piece 4b that is installed between the one side piece 4 and the inner side piece 4a of the fixed frame 2, respectively. It is attached. Therefore, this biasing means 13 biases the movable inner case 5 in the tilting direction in which it normally pops out, and this biasing force rotates the drive gear 11 together with the support shaft 12, and the toothed portion 10 that meshes with the drive gear 11 rotates together with the support shaft 12. The movable inner case 5 is tilted clockwise in FIG. 3, that is, in the direction of protruding from the fixed frame 2, using the support pins 6, 6 as fulcrums. In addition, the fixed frame 2
The adjustment gear 1 is attached to the inner side piece 4a along with the support shaft 15.
6 is rotatably supported, and this adjustment gear 16 is located on the front side (on the right side in FIG. 3) of the engagement point between the drive gear 11 and the toothed portion 10,
A resistor 17 is installed at one end of the support shaft 15 to provide a desired resistance to the rotation of the support shaft 15, and when the movable inner case 5 is tilted, the toothed portion 10
A desired resistance force is applied to the adjustment gear 16 which rotates simultaneously through meshing with the movable inner case 5, thereby smoothing the tilting movement of the movable inner case 5. Note that this resistor 17 is usually provided with a disc or the like at the end of the support shaft 15, and this disc or the like is covered with a case together with the shaft, and grease or the like of a desired viscosity is sealed in the case, and the support shaft 16 is configured to provide the desired resistance.

A substantially L-shaped locking arm 18 is tiltably supported at its bent portion by a support pin 18C on the lower front surface (right side in FIG. 3) of the fixed frame 2.
At the end of the hanging piece 18a, a locking protrusion 19 is projected outward as shown in FIGS. 2 and 6, and at the end of the horizontal piece 18b, a locking protrusion 19 is provided that extends through the frame piece 3 of the fixed frame 2. An operation button 21 that can be moved in and out of the through hole 20 is integrally formed. As shown in FIG. 6, a guide rod 22 is suspended from the lower surface of the operation button 21 and loosely inserted into the groove of the horizontal protrusion 2a of the fixed frame 2, and the operation button 21 and the horizontal protrusion 2a are connected to each other. A spring means 23 wound around the guide rod 22 is loaded between the guide rods 22 and always urges the operation button 21 upward (in the direction of protruding from the fixed frame 2). On the other hand, at the front part of the movable inner case 5 facing the locking protrusion 19, as shown in FIG. The locking state is maintained by the spring means 23 on the lower surface of the operation button 21, as the locking arm 18 is always subjected to an urging force in the counterclockwise direction in FIG. In addition, 25 in the figure is the movable inner case 5.
This is a stopper that prevents the needle from jumping out more than necessary.

The air conditioner 1 of this embodiment is configured as described above, and its operation will be described in detail below.

Now, when the movable inner case 5 is in the stored state as shown by the solid line in FIG. Since the stored state is maintained, the air from the duct D passes through the upper and lower openings of the movable inner case 5 and flows upward into the passenger compartment, just like a normal stationary ventilation grille. It is something that is blown out. In order to pop out the movable inner case 5, first, the driver or fellow passenger presses down the operation button 21 located on the inside of the vehicle against the biasing force of the spring means 23, and the locking arm 18 is support pin 1
It is tilted clockwise in Fig. 6 around 8C,
The locking protrusion 19 of the hanging piece 18a is disengaged from the locking claw 24 and released from the locking claw 24.

Then, the driving gear 11 is rotated together with the support shaft 12 by the urging force of the urging means 13, such as a coil spring, whose elasticity has been accumulated through the movable inner case 5. 10, the entire movable inner case 5 is positively tilted clockwise in FIG. 3 using the support pins 6, 6 as fulcrums.
Therefore, the entire movable inner case 5 protrudes into the vehicle interior relative to the fixed frame 2. (Refer to the imaginary line in Fig. 3) In this case, the range in which the movable inner case 5 protrudes is as shown in Fig. 3, when the stopper 25 is
In this example, the angle is set to be in the range of approximately 30° to 45°.

Further, when the movable inner case 5 pops out and tilts, the adjustment gear 16 that meshes with the movement (tilting) of the toothed portion 10 of the movable inner case 5
and the support shaft 15 are both rotated, but since the adjustment gear 16 is given a desired resistance by the resistor 17, this resistance is directly transmitted to the toothed part 10, and the tilting of the movable inner case 5 is It slows down the speed and makes it smoother.

Therefore, unlike the case described above, the air from the duct D is blown out in a substantially horizontal direction within the vehicle interior due to the movable inner case 5 in the blown-out state as described above.

It goes without saying that the direction of the wind can also be changed using the movable blades 7-7.

Next, when storing the movable inner case 5 in the protruding state, when the movable inner case 5 is pushed down as it is, the locking arm 18 biased by the locking claw 24 of the movable inner case 5 and the spring means 23 The locking protrusion 19 automatically becomes locked, and the stored state is maintained. In this case, since the drive gear 11 is rotated in the biasing means 13 in the opposite manner to that described above, elasticity is accumulated as the drive gear 11 rotates.

Although the air conditioner 1 is assembled on the upper surface of the instrument panel P in this embodiment, the present invention is not limited to this, and the protruding direction (tilting direction) is not limited to that shown in the drawings. Furthermore, all the blades arranged in the movable inner case 5 may be movable.

As described in detail above, the present invention is an air conditioner that is attached to an opening on the inside of a duct of a duct built into an automobile instrument panel, etc., and a fixing frame is attached to the opening. A movable inner case connected to the duct is tiltably supported so as to be able to pop out and be stored, and a biasing member is provided between the fixed frame and the movable inner case to always bias the movable inner case in the pop-out direction. The movable inner case is provided with a biasing means, a locking means for maintaining the stored state of the movable inner case against the biasing force of the biasing means, and an operating means for releasing the locked state of the locking means from the outside. This allows air to circulate between the duct and the interior of the vehicle even when the movable inner case is in the stored state, and when the movable inner case pops out, it can be moved automatically by simply operating the operating means. This has the advantage that the operation can be performed with a single touch, making it easy to handle. Furthermore, when the movable inner case is in the protruding state, the desired wind direction can be obtained arbitrarily, and in addition to the above-mentioned advantages, the usability of this type of air conditioner can be greatly improved.
