Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an air-conditioning air blowing mode blown out from an air-conditioning system, an automatic variable mode for automatically and periodically changing the wind direction, and a manual operation mode. In the swing louver type air conditioning outlet that can switch to the fixed mode that sets and fixes the wind direction to the desired direction by adjustment,
The present invention relates to the structure of a fin connecting frame that connects and supports a plurality of fin bodies that adjust the air flow direction of air conditioning.

[Prior Art] Conventionally, as a structure of an air-conditioning air outlet in an air conditioner, a fin body for adjusting a blowing direction is provided with a swing shaft, and the fin body is provided with the swing shaft via the swing shaft. A so-called swing louver type in which the fin body is continuously reciprocally swung about the swing shaft by driving a power source such as an electric motor is generally well known. ing.

In addition, in this type of air-conditioning outlet, the air-conditioning air blowing mode is changed automatically and periodically according to the automatic swinging of the fin body, and the fin body direction is manually operated. It is known that the wind direction can be switched to a fixed mode in which the wind direction is set and fixed in a desired direction by adjustment (see, for example, Japanese Patent Publication No. 58-4256).

However, when the blowing mode can be switched as described above, the fin body transmits the driving force of the power source to the fin body side when the power source is stopped when switching from the automatic variable mode to the fixed mode. Since the swinging motion is stopped via the power transmission mechanism, in order to manually adjust the orientation of the fin body, the connection between the fin body and the power transmission mechanism is released. It is necessary to provide a clutch mechanism that can swing the fin body by manual force.

In the patent publications relating to the above-mentioned prior art, in order to solve the troubles such as the manual switching operation of the clutch mechanism and the problems such as forgetting to disengage, a friction type sliding mechanism or a ratchet wheel is provided at a connecting portion between the power transmission mechanism and the fin body. By adopting an overrunning clutch mechanism such as the above, there is disclosed a structure in which the connection between the both is automatically released in association with the adjustment of the wind direction by the manual operation.

However, in the above-described conventional structure, when adjusting the wind direction manually, it is necessary to overcome the connecting force between the fin body and the power transmission mechanism to move the connecting portions of the two, so that manual adjustment is required with long-term use. If it is repeated frequently, the connecting force between the two becomes weak, and there is a problem that the swing drive of the fin body in the automatic variable mode is hindered.

With respect to such a problem, the applicant of the present application has proposed in Japanese Patent Application No. 01-47105 an air conditioning blow-out device provided with a biaxial swing louver. That is, by providing the fin body with a first swing shaft that serves as a swing fulcrum when driving the power source and a second swing shaft that serves as a swing fulcrum during manual operation,
The blower mode can be switched without using the clutch mechanism, and the above-mentioned problems can be solved.

By the way, in the swing louver type air-conditioning air outlet, in order to determine the maximum air-blowing range (deflection range) of the conditioned air, a regulation means for regulating the maximum swing angle of the fin body is usually provided.

[Problems to be Solved by the Invention] However, in the above-described two-axis swing louver, two fin shafts are provided in each fin body, and the respective pivot shafts are connected by link members. Compared with the one-axis type, the internal structure of the air conditioning outlet becomes complicated to some extent, and the work of assembling the fin body on the case side becomes difficult to some extent. Therefore, when the regulation means is provided, it is necessary to take care so as not to further complicate the internal structure of the air outlet.

Therefore, the present invention can regulate the maximum swing angle of the fin body in an air-conditioning outlet provided with a two-axis swing louver without complicating the internal structure of the outlet. An object of the present invention is to provide a structure of a fin connecting frame of an air conditioning outlet, which can improve the assembling property when assembling the fin body to the case side.

[Means for Solving the Problems] Therefore, the present invention provides a first swing shaft connected to a first link member that can be manually operated and a second link member that can be driven by a power source. A plurality of wind direction adjusting fin bodies having a second swing shaft connected thereto are provided, and each of these fin bodies swings with the first swing shaft as a fixed fulcrum when the power source is driven, while manually. At the time of adjustment, at least one of the first and second link members has a rectangular shape in an air conditioning outlet provided with a swing louver configured to swing with the second swing shaft as a fixed fulcrum. Of the frame body, and a bearing that rotatably supports the fin body is provided in a portion of the frame body that is orthogonal to the fin body, while the fin body is provided in a portion of the frame body that is parallel to the fin body. The stopper part that regulates the maximum swing angle of It was made to be done.

[Advantage of the Invention] According to the present invention, since the stopper portion is provided in a portion of the frame body parallel to the fin body, it is not necessary to provide a stopper separately from the fin body supporting mechanism, and thus the air conditioning outlet port. The maximum blowing range of the conditioned air can be regulated with a simple configuration without complicating the internal structure of the. Further, since at least one of the first and second link members is formed of a rectangular frame body, a plurality of fin bodies are previously assembled to the frame body to form a unit, and then this unit is used as a case. By incorporating the fin body, the workability of assembling the fin body on the case side can be improved.

Is provided in this groove 28a.
As shown in the figure, a leaf spring 31 having a notch 31b for positioning and an attachment 31a having a predetermined width is mounted.

The vertical fins 11, 12, 13 are attached to the louver frame 26, and the leaf spring 31 is attached to the bottom plate 28 to form a unit body. By assembling the unit body in the louver housing 1, The work of assembling the fins 11, 12, 13 can be simplified. At this time, the bottom plate 28 of the louver frame 26 is assembled so as to be fitted into the guide groove 1a formed by the stepped portion provided in the front housing 15 and the front end portion of the rear housing 16 and extending in the left-right direction ( (See FIG. 3).

When the vertical fins 11, 12, 13 swing to the left and right, a force in the left-right direction acts on the louver frame 26 along with the swing motion, and the bottom plate 28 of the louver frame 26 and the guide groove 1a
A frictional force corresponding to the biasing force of the leaf spring 31 is generated between and.
The spring characteristics of the leaf spring 31 and the shape and size of its mounting portion are such that the frictional force generated at this time is sufficiently larger than the rotational frictional force of the first swing shaft 24 generated by the bearing portions 27h and 28h. Is set in advance.

Further, the upper plate 27 of the louver frame 26 is provided with a substantially triangular overhang portion 27a extending to the front side, and an engaging pin 32 extending downward is fixed to the apex portion of the overhang portion 27a. Engages with a two-claw fork portion 10a formed on the rear portion of the operation knob 10 (see FIGS. 2 and 3). Therefore, when the operation knob 10 is slid to the left and right along the horizontal fin 8, the louver frame 26 is moved to the left and right together with the engaging pin 32, and at this time, the vertical fins 11, 12, and 13 are moved to the respective first fins. The two swing shafts 25 are each swung about a fixed fulcrum.

On the other hand, all of the second swing shafts 25 of the vertical fins 11, 12, 13 are
The link member is rotatably supported by a single link member 41 extending in the left-right direction across the rear housing 16.

It can be slid left and right in 1a. As a result, the vertical fins 11, 12, 13 are each swung in the left-right direction with the second swing shaft 25 as a fulcrum. At this time, since each of the second swing shafts 25 is rotatably supported by the link member 41, the link members are moved in accordance with the swing motion of the vertical fins 11, 12, 13.
41 itself does not move left or right.

That is, by sliding the operation knob 10 to the left and right, the vertical fins 11, 12, and 13 can be swung to the left and right with the second swing shafts 25 as fixed fulcrums. It is possible to change the left-right direction of 12,13. Further, the vertical direction of the horizontal fins 8 and 9 can be changed by rotating the operation knob 10 up and down, and the wind direction of the conditioned air can be manually set to desired directions in both left and right and up and down directions. be able to.

On the other hand, when the electric motor 46 is driven, the crank plate 45 is rotated along with the driving of the motor, and the crank pin 44 is rotated around the central axis of the crank plate 45 and slides in the elongated hole 42a. The link member 41
Is reciprocated in the left-right direction. As a result, the vertical fins 11, 12, 13 are reciprocally rocked in the left-right direction with the first rocking shafts 24 as fulcrums. At this time, the magnitude of the frictional force generated between the leaf spring 31 and the guide groove 1a depends on the first swing shaft.
Since it is set to be sufficiently larger than the rotational frictional force of 24, the louver frame 26 itself does not move to the left or right due to the reciprocating swing motion of the vertical fins 11, 12, 13.

That is, by driving the electric motor 46, each of the vertical swing shafts 24 is used as a fixed fulcrum and each of the vertical fins 11, 1 is
