Abstract

PURPOSE:To make it possible to adjust the orientation of the fins at the time of stopping the automatic oscillation by providing a second switch which comprises a contact plate having a noncontinuity part in its regulating circuit and a contact point sliding on the contact plate, one of them being movable in conjunction with the movement of the fins and the other being manually movable by a control means. CONSTITUTION:When the first switch SW1 is switched on with the control knob 6 set in the middle position, the rotation of an electric motor M is transmitted to a link member 3 through a crank plate 4 to cause the fins 2 to continuously oscillate back and forth. When the switch SW1 is switched off, the drive circuit C1 is opened, but, so long as the oscillating fins 2 are out of their middle position, the adjusting switch SW2 remains on as the contact plate 7 and the contact point 5 maintains the mutual contact. When the fins 2 are aligned in the middle position, the contact point 5 comes in contact with the noncontinuity part 72 of the contact plate, whereupon the adjusting switch SW2 is indeed switched off to cause the fins 2 to stop the oscillation. When the control knob 6 is moved to the right under such a condition, the adjusting switch SW2 is again switched on to cause the fins 2 to oscillate to the right. As the contact point 5 comes to the noncontinuity part 72, the fins 2 stops right there.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a blade direction adjusting device for adjusting the direction of wind, which is pivotably supported on an air conditioner outlet so as to be able to move automatically.

(Prior art) For example, in a swing louver for an automobile, a fin body arranged at the wind outlet for adjusting the wind direction is pivoted to the upper and lower louver frames via a swing shaft, and is powered by a power source such as an electric motor. A mechanism that allows automatic swinging from side to side using the swinging shaft as a fulcrum, and also allows switching to manual swinging using the swinging shaft as a fulcrum in order to manually set the wind direction in a desired direction when the automatic movement is stopped. have been proposed (for example,
(Japanese Patent Publication No. 58-4256), in such a mechanism, when the drive source stops, the direction in which the fin body moves and stops is not uniform, so the wind direction is manually adjusted after the fin body stops swinging.

(Problem to be Solved by the Invention) However, in order to manually adjust the direction of the fin body, the link between the stopped drive transmission mechanism and the fin body must be released, and the fin body can be swung by manual force. It is necessary to include a clutch mechanism (phase adjustment means). In order to eliminate switching operations, such clutch mechanisms generally employ a friction-type sliding mechanism or an overrunning clutch mechanism such as a ratchet wheel to connect with the drive transmission section, and automatically engage when the manual operation is performed. It is necessary to have a structure that can be released, but if the latter automatic switching is used, it is necessary to overcome the connection part with the drive transmission part and move the connection part when it is manual, and if used repeatedly over a long period of time, the retaining blade of the connection part becomes weak. This poses a problem in that it interferes with the swinging drive during automatic swinging.

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

(Means for Achieving the Object) The present invention provides a device capable of continuously swinging a blade body for adjusting the wind direction of an air conditioner outlet by driving an electric motor, which includes a first switch for intermittent continuous rocking operation of the blade body. a contact plate having a non-conducting portion in part, and a contact in sliding contact with the contact plate, one of which is movable in conjunction with the blade, and the other is moved by an operating means that allows manual movement. A device for adjusting the direction of a blade body of an air conditioner outlet is provided, the gist of which is to include an adjustment circuit having a second switch that enables the blade body direction of an air conditioner outlet.

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

(Operation) According to the present invention, after the swinging is stopped by the first switch (
(See Fig. 6), and if the contact point or contact plate is moved via the operating means, the second switch is turned on again (see Fig. 7(a)), and the blade body starts to vibrate electrically. Along with this operation, either the contact or the contact plate is interlocked, so when the contact reaches the non-conducting part of the contact plate again, the second switch is turned off (see Figure 7 (b)), and the blade body is powered. stops. Therefore, the direction of the blade body can be adjusted using the electric mechanism by adjusting the position of the operating means. In addition,
By setting the operating means at a predetermined position in advance, the direction of the blade body when automatic swinging stops is set.

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

(Embodiment) Fig. 1 is an exploded perspective view showing the entire case in which the first embodiment of the air conditioner outlet blade direction adjustment device according to the present invention is applied to a swing louver of an automobile, and Fig. 2 is a cross-sectional view thereof. Side view,
FIG. 3 is a front view thereof, FIG. 4 is an exploded view of the device of the present invention, and FIG. 5 is a plan view showing a state in which a contact plate and a contact are joined.

In the drawing, case C has horizontal blades extending laterally.
A plurality of case C are pivotally supported in front of the air conditioner Suita outlet 1, and an adjustment device M according to the present invention is installed at the rear of the case C.

The plurality of fin bodies 2 extending in the vertical direction are placed side by side at a predetermined interval in the air conditioning Suita outlet 1 having a horizontally long opening, and each fin body 2 has a swing shaft 2 protruding from the upper and lower ends of the center thereof.
1.21 to the upper and lower louver frames 1112 so as to be able to swing from side to side, and each of the fin bodies 2 is connected to the link member 3 via a shaft 22 protruding from the upper end of the fin body 2.
It is pivoted so that it can swing left and right, and is interlocked. A right side end 31 of the link member 3 extends at a right angle, and an elongated hole 32 bored therein has an engager protruding from the upper surface of a crank disk 4 which is rotationally driven by an electric motor M via a gear box G. 41 slidably enters, and the link member 3 is caused to perform reciprocating motion by the rotational drive of the crank disk 4, thereby forming an automatic rocking mechanism with the rocking shaft 21 of each fin body 2 as the rocking center.

The blade direction adjustment device according to the present invention is incorporated in the automatic swing mechanism. That is, as shown in FIG. 4, a contactor 5 is integrally attached to the front lower end of the blade body 2, is swingable in conjunction with the swinging of the blade body 2, and is opposed to the blade body 2. A fan-shaped operation knob 6 is disposed coaxially with the swing shaft 21, and is supported so that it can be moved independently by hand. An arc-shaped contact plate 7 is attached. The contact plate 7 has a non-conducting portion 72 formed by cutting out the substantially central outer side of the conductive portion 71 thereof.

As shown in FIG. 6, the contact plate 7 and the contact 5 are connected to a blade drive circuit C1 consisting of an electric motor M, a power source S, and a first switch SW1, and a second switch SW2.
are connected in parallel via lead wires L1 and L2 to form a manual adjustment circuit C2.

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 contactor 5 may be formed on the operation knob 6 side.

In the above configuration, when the operating knob 6 is set to the center position shown in FIG. 6 and the first switch SWl is turned on, the rotation by the electric motor M is transmitted to the link member 3 via the crank disk 4, and the blade body 2 continuously swings the head from side to side. Therefore, when the tsl switch SWI is turned off, the drive circuit C1 is opened, but if the swinging blade body 2 is not in the center position, the contact plate 7 and the contactor 5 are in contact with each other, and as a result, the adjustment switch 'lJ2 is in the on state, and when the blade body 2 reaches the center position, the contact 5 comes into contact with the non-conducting part 72 of the contact plate 51, and the adjustment switch SW2 is turned off for the first time, causing the electric movement of the blade body 2. stops (see Figure 6). Therefore, when the operation knob 6 is moved to the right, the contact plate 7 and the contactor 5 come into contact again as shown in FIG. 7(a), and the adjustment switch SW
2 is turned on, the blade body 2 swings to the right, and when the contactor 5 comes to the position shown in FIG. 7(b), the adjustment switch SW2 is turned off and the blade body 2 stops. Operation knob 6 from the state shown in Figure 6
If the blade body 2 is moved to the left, the blade body 2 will swing to the left by the amount of movement of the operating knob 6 in the same way as shown in FIG. 7 and then stop.

In the above embodiment, the contactor 5 or the contact plate 7 is interlocked using the swinging motion of the blade body 2; however, as shown in FIG. It may also be linked to the rocking motion of step 2. In this case, linear contact plates 7' are disposed extending in the direction of the reciprocating power at required locations on the link member 30, which is reciprocated by motor drive, while the operating knob 6' is connected to a guide member 8 that extends parallel to the link member 3. Slidably mounted by manual operation on the
It is constructed by protruding a contact 5' from the operation knob 6' so that it can come into contact with the contact plate 7''.In this case as well, the arrangement position of the contact 5° and the milling/tact plate 7' is fixed. It is also possible to exchange them.

(Effects of the Invention) As is clear from the above description, according to the present invention, in a device that can continuously swing the air conditioning outlet wind direction adjusting blade by driving an electric motor, the continuous swinging operation of the blade can be performed. It consists of a drive circuit having a first switch for switching on and off, a contact plate having a non-conducting part in part, and a contact that slides on this, one of which is movable in conjunction with the blade body, and the other of which is movable. Since the adjustment circuit includes a second switch that can be moved by a manually movable operating means, it is possible to switch between automatic and manual movements by using electric drive after automatic movement stops, without using a clutch means to switch between automatic movement and manual movement. The blade direction can be adjusted to the desired direction. Therefore, there is no problem in operation due to wear and tear on the clutch mechanism, and the clutch mechanism has excellent durability, simple structure, and excellent operability.
