Description

Description: TECHNICAL FIELD The present invention relates to a blade direction adjusting device for adjusting a wind direction direction pivotally supported by an air conditioning outlet so as to be capable of automatically swinging.

(Prior Art) For example, in a swing louver for an automobile, a fin body for adjusting a wind direction arranged at a wind outlet is pivotally supported on a vertical louver frame via a swing shaft, and a power source such as an electric motor is used. It is possible to automatically swing to the left and right with the swing shaft as a fulcrum, and to switch to manual swing with the swing shaft as a fulcrum to manually set the wind direction in a desired direction when the automatic swing is stopped. Mechanisms have been proposed (eg,
(Japanese Patent Publication No. 58-4256), in such a mechanism, when the drive source stops, the direction in which the fin body swings is not uniform, so
After the swing of the fin body is stopped, the wind direction is manually adjusted.

(Problems to be Solved by the Invention) However, in order to manually adjust the direction of the fin body, the connection between the stopped drive transmission mechanism and the fin body is released, and the fin body can be swung by a manual force. It is necessary to provide a clutch mechanism (phase adjusting means). In order to eliminate the switching operation, such a clutch mechanism generally adopts a friction type sliding mechanism or an overrunning clutch mechanism such as a ratchet wheel for linking with the drive transmission section so that the link can be automatically released in association with a manual operation. However, if the latter automatic switching is used, it is necessary to overcome the linking force with the drive transmission part in manual operation and move the connecting part. However, there is a problem in that the rocking drive becomes difficult.

Therefore, an object of the present invention is to make it possible to adjust the direction of the blade body when the automatic swing is stopped by using the automatic swing drive mechanism without using the clutch mechanism that switches between the automatic swing and the manual swing. To do.

(Means for Achieving the Object) The present invention relates to a device capable of continuously swinging an air conditioning outlet wind direction adjusting vane body by driving an electric motor, in which a first switch for intermittently performing a swinging continuous operation of the vane body is provided. It has a drive circuit, a contact plate partially having a non-conducting portion, and a contact slidingly contacting the contact plate, one of which is movable in conjunction with the blade body and the other is manually movable. A vane body direction adjusting device for an air conditioning outlet is provided with an adjusting circuit having a second switch that is enabled.

In the present invention, it is preferable that the operating means is coaxial with the swing axis of the blade body and has a fan-shaped knob shape so as to cover the swing angle. On the other hand, it is preferable that the contact plate also has an arc shape so as to cover the entire swing angle range of the blade body.

(Operation) According to the present invention, after the oscillation is stopped by the first switch (see FIG. 6), if the contact or the contact plate is moved through the operating means, the second switch is turned on again (the first switch). As shown in FIG. 7 (a), the blade body starts electric oscillation, but with this operation, either the contact or the contact plate is interlocked, and when the contact reaches the non-conducting portion of the contact plate again, the second The switch is turned off (see FIG. 7 (b)), and the blades are de-energized. Therefore, the direction of the blade body can be adjusted by utilizing the electric mechanism by adjusting the position of the operating means. If the operating means is set at a predetermined position in advance, the direction of the blade body when the automatic swing is stopped is set.

Hereinafter, the present invention will be described in detail based on specific examples shown in the accompanying drawings.

A plurality of sheets are pivotally supported in front of the air-conditioning outlet 1, and the adjusting device M according to the present invention is mounted behind the case C. The plurality of fin bodies 2 extending in the vertical direction are juxtaposed at predetermined intervals in an air-conditioning outlet 1 having a horizontally long opening, and each fin body 2 has a swing shaft 21 projecting at the upper and lower ends of its center.
The fin body 2 is pivotally supported by the upper and lower louver frames 11 and 12 so as to be capable of swinging left and right via 21 and the fin body 2 is capable of swinging left and right with respect to the link member 3 through a shaft 22 projecting at an upper end behind the fin body 2. It is pivotally supported by. The right end 31 of the link member 3 is extended at a right angle, and an engaging piece projecting to the upper surface of the crank disk 4 which is rotationally driven by an electric motor W through a gear box G into an elongated hole 32 formed therein. 41 slidably plunges into the link member 3 by the rotational drive of the crank plate 4 to reciprocate, thereby forming an automatic swing mechanism having the swing shaft 21 of each fin body 2 as the swing center.

The blade body direction adjusting device according to the present invention is incorporated in the automatic rocking mechanism. That is, as shown in FIG. 4, a contactor 5 is integrally attached to the lower front end of the blade body 2 and can swing in conjunction with the swinging motion of the blade body 2. A fan-shaped operation knob 6 is provided coaxially with the rocking shaft 21 and independently supported so as to be manually rockable. The arc-shaped contact plate 7 is attached. The contact plate 7 is formed with a non-conducting portion 72 by cutting out the substantially central outside of the conducting portion 71.

As shown in FIG. 6, the contact plate 7 and the contactor 5 are provided with a lead wire L so that a blade switch circuit C1 composed of an electric motor M, a power source S and a first switch SW1 constitutes a second switch SW2. ₁ and L ₂ are connected in parallel to form a manual adjustment circuit C 2.

Instead of the above configuration, as shown in FIGS. 8 and 9, the contact plate 7 may be attached to the blade body 2 side via the fan-shaped plate 71 while the contact 5 is formed on the operation knob 6 side.

In the above configuration, when the operation knob 6 is set to the center position shown in FIG. 6 and the first switch SW1 is turned on, the rotation of the electric motor M is rotated by the link member 3 via the crank board 4.

The electric swing stops (see FIG. 6). Then, when the operation knob 6 is moved rightward, the contact plate 7 and the contactor 5 again come into contact with each other as shown in FIG. 7A, the adjustment switch SW2 is turned on, and the blade body 2 is moved rightward. When the contactor 5 oscillates and reaches the position shown in FIG. 7 (b), the adjustment switch SW2 is turned off and the blade body 2 is stopped. If the operation knob 6 is moved to the left from the state shown in FIG. 6, the blade body 2 is swung to the left by the amount of movement of the operation knob 6 and stopped in the same manner as shown in FIG. Become.

In the above embodiment, the contactor 5 or the contact plate 7 is interlocked by utilizing the swing of the blade body 2, but the blade member 2 is utilized by using the link member 3 of the blade body 2 as shown in FIG. It may be interlocked with the swing of. In this case, a linear contact plate 7'is arranged to extend in the reciprocating direction at a required position of the link member 3 which is reciprocally driven by a motor, while an operation knob 6'is extended in parallel with the link member 3. 8 is slidably attached by a manual operation, a contact 5'projects from the operation knob 6 ', and is provided so as to be contactable with the contact plate 7'.
