Abstract

PURPOSE:To enable any one of louvers to be fixed by cutting it off from drive of a motor by dividing the shafts of air-flow direction change-over louvers provided at a plurality of air outlet ports from shafts to be operated by the motor, connecting the shafts to be operated by the motor to one another with universal joints and detachably mounting the shafts of the louvers to the shafts. CONSTITUTION:In the case where, for example, air-flow direction change-over louvers 3a - d are made to work in linkage with one another, power transmission shafts 5a - d and connecting rods 4a - d are coupled together by universal joints 6, and a power transmission bar 2 and a driving motor 1 are mounted to one of the connecting rods so that the shafts 5a - d are reciprocatingly rotated by the drive of the motor 1. The shafts 5a - d are penetrated through the hollow shafts of the louvers 3a - d to permit them to freely move, and a louver fixing bush 7 fixed to the shafts 5a - d is mounted to one end of each of the louvers while a bush 8 fixed to a bearing 9 is mounted to the other end thereof so that each louver is not simultaneously held by both the bushes 7 and 8. Thus, when fitted to the bushes 7, the louvers rotate in agreement with the rotation of the shafts 5a - d and, when any of them are fitted to the bushes 8, such louvers are fixed to the bearings 9 without regard to the rotation of the shafts 5a - d.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a louver swinging mechanism for an air conditioner having a plurality of air outlets, each of which is provided with a wind direction switching louver.

[Conventional technology]

A conventional device, as disclosed in Japanese Utility Model Application Laid-Open No. 60-178742, uses two electric motors to move a plurality of louvers.

[Problem to be solved by the invention]

In the above conventional technology, since the shafts of the wind direction switching louvers are directly connected by a universal joint, only one of the plurality of wind direction switching louvers
There was a problem in that one of them could not be removed from the drive by the electric motor and fixed.

An object of the present invention is to provide a simple mechanism in which any one of a plurality of wind direction switching louvers can be removed and fixed from being driven by an electric motor, and the other louvers can be driven by the electric motor.

[Means to solve the problem]

In order to achieve the above object, the present invention separates the shaft of the wind direction switching louver and the shaft driven by the electric motor, connects the shaft driven by the electric motor with a universal joint, and transmits power to this shaft. A mechanism is provided that allows the wind direction switching louver to be attached to and detached from the shaft that is driven through the shaft.

[Effect]

The driving shafts are each connected by a universal joint and perform reciprocating rotational motion in response to the movement of the electric motor.

The wind direction switching louver can be securely fixed to this driving shaft with a fixing bush. Furthermore, when the wind direction switching louver is separated from the driving shaft, it can be fixed to the bearing with another fixing bushing, so that the movement of the driving shaft is not obstructed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a diagram of a drive mechanism in which there are four air outlets and four wind direction switching louvers are moved in conjunction with each other. The four power transmission shafts 5a to b and the connecting rods 4 a = d are connected by the universal joint 6 at the joint, and the power transmitting bar 2 and the drive motor 1 are attached to the connecting rods among the four. . When the drive motor 1 moves, the power transmission bar 2 moves up and down, and this movement is transmitted to the connecting rod 4d, which in turn causes the four power transmission shafts 5 a = d to reciprocate and rotate through the universal joint 6. ing. Each of these four power transmission shafts 5a to 5d has a wind direction switching louver 3.
A" d is the installation. As shown in Fig. 2, the wind direction switching louver 3a = d has a hollow shaft, and the power transmission shaft 5a = d passes through the inside of this hollow shaft. , so that they can move freely relative to each other.There are louver fixing bushes at both ends of the wind direction switching louver 3a = d, and a power transmission shaft 5a at one end.
A louver fixing bush A7 is fixed to one end d, and a louver fixing bush B8 fixed to a bearing 9 is attached to the other end. The hollow shafts of the wind direction switching louvers 3a to 3d are engaged with either of the louver fixing bushes a7 or b8, and the louvers are fixed.
Wind direction switching louver 3a on louver fixing bushes a7 and b8
The length of the louver was adjusted so that the parts 1 to d do not fit together at the same time. This state is shown in FIGS. 3 and 4.

FIG. 3 shows a state in which the wind direction switching louvers 3a to 3d are moved to the left side and engaged with the louver fixing bushing a. As a result, the wind direction switching louvers 3 a '' d are fixed to the power transmission shafts 5 a - d, and the louvers 3 a = d also move in accordance with the movement of the shafts 5 a - d. Fig. 4 shows the wind direction switching louvers 3 a - d. is moved to the right side and fitted to the louver fixing bush b.This allows it to be fixed to the bearing 9 regardless of the movement of the power transmission shaft 5a = d.This allows the movement of the drive motor 1 to be fixed. The four wind direction switching louvers can be moved in conjunction with each other.Also, when it is desired to fix any of the four wind direction switching louvers 3a to d, the louvers 3a = d can be moved from the power transmission shaft 5a to 5d. It can be removed and fixed.

According to this embodiment, it is possible to provide a mechanism that can inexpensively move the wind direction switching louvers of the four air outlets and fix any of the louvers.

〔Effect of the invention〕

According to the present invention, a mechanism capable of moving a plurality of wind direction switching louvers with a simple structure and fixing some of the wind direction switching louvers can be provided at low cost and with good assemblability.
