Air blasting guide plates 20, 20a extending to the depth are hinged on deep side end parts of the upper wall 19 and the lower wall 19a, pins 22 are projectively provided toward a side surface of the air blasting case 1 on both sides of deep side end parts of these air blasting guide plates, and a guide groove to guide the pins 22 in the longitudinal direction is formed along a bottom surface of the air blasting case 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barrel having a louver formed of a plurality of lateral fins and a plurality of fins arranged so that the left and right wind directions can be adjusted in the direction orthogonal to the louver. The present invention relates to an automobile register pivotally attached to both side surfaces of a barrel storage area formed at an outlet of a blower case.

[0002]

2. Description of the Related Art In a register of this type, when the barrel is pivotally operated to adjust the wind direction downward or upward, the lower wall or upper wall of the barrel occupies a position facing each other in the wind direction, so that the air volume decreases. Or, there is a problem that the air flow is disturbed. Therefore, the applicant of the present invention has proposed a register in which an upper wall and a lower wall are configured as openable and closable lids according to Japanese Patent Laid-Open No. 8-80731.

Thus, when the wind direction is adjusted by moving the barrel downward or upward, the lid-type lower wall or upper wall is opened to a position along the wind direction, so that the reduction of the air volume or the turbulence of the air flow is suppressed. .

[0004]

DISCLOSURE OF THE INVENTION The present invention is capable of suppressing the disturbance of the wind direction when adjusting the vertical wind direction with a simple additional structure without modifying the upper and lower wall portions of the barrel as described above. The purpose of the present invention is to provide a car register.

[0005]

In order to achieve this object, the present invention provides a front louver formed by a plurality of lateral fins and a louver which is arranged in a direction orthogonal to the fins behind the louver. A barrel having a plurality of fins that are movably arranged is pivotally attached to both side surfaces of a barrel storage area formed in the blower case, and upper and lower walls of the barrel are pivoted. It is formed in an arc shape centering on the wearing position, and the upper and lower surfaces of the barrel storage area are also formed in an arc shape correspondingly, so that the vertical wind direction is adjusted by the rotation operation of the barrel, and the fins behind the louver are adjusted. In a vehicle register in which the left and right wind directions are adjusted by a turning operation, a ventilation guide plate extending inward is hinged to the rear side end portions of the upper and lower walls of the barrel, and the ventilation guide plate is also used. Blower case on both sides of the back end Projecting pin toward the side surface, the side surface, characterized in that the pins along the bottom surface of the blower case forming a guide groove for guiding the longitudinal direction.

[0006] When the barrel is set downward, the blower guide plate on the lower side pushes the pin inward and becomes diagonally upward along the wind direction, and the blown air trying to dive into the back side of the lower wall is
It is guided while being rectified into the barrel along the lower air guide plate. The upper air guide plate moves forward and enters the barrel storage area along its upper surface, so that the flow is not disturbed. When the barrel is set upward, the upper air guide plate moves backward and becomes obliquely downward, and the lower air guide plate moves forward and enters the barrel storage area along the lower surface thereof.

[0007]

1 and 2 show a register according to an embodiment of the present invention. For example, a rear surface is opened in a barrel storage area 1a of a blower case 1 attached to a blower duct of an instrument panel. The barrel 10 is housed so as to be vertically rotatable. That is, barrel 1
The side surface 10a of 0 is pivotally attached to the barrel storage area portion of the side surface 1b of the blower case 1, and the upper wall 19 and the lower wall 19a of the barrel 10 are formed in an arc shape centering on this pivoted position to store the barrel. The upper and lower surfaces of the region 1a are also formed in a corresponding arc shape along the rotation path of the barrel 10.

Between both side surfaces 10a of the barrel 10, there is provided a louver 15 formed by a plurality of fins which are parallel to each other in the lateral direction and along the wind direction, and a knob 16a is provided behind the louver 15.
The plurality of fins 16 for adjusting the left and right wind directions are arranged in the horizontal direction by the horizontal rotation operation.

Although such a structure is basically known, according to the present invention, the upper wall 19 and the lower wall 19a are provided at the rear end portions of the blower case 1 with an integral hinge portion 21 between the blower cases. Blower guide plates 20, 20a toward the back of 1
Are formed. The lateral width of the blower guide plate substantially corresponds to the lateral width of the blower case 1, and the depth dimension is set so as to obtain a sufficient rectifying action. Further, the pins 22 are formed so as to project in the lateral direction on both sides of the rear end portion thereof, and have a long groove shape which guides the pins 22 in the front-rear direction along the bottom surface 1c of the side surface 1b of the blower case 1. A guide groove 25 is formed.

The operation of the register thus constructed will be described with reference to FIG. As shown by the solid line in the figure, when the barrel 10 is set downward, the lower blower guide plate 20a is bent by the integral hinge portion 21 while pushing the pin 22 inward along the guide groove 25. The state is upwards toward the barrel 10. As a result, the blast of the lower portion that tries to get under the bottom wall 19a of the barrel 10 is guided while being rectified into the barrel 10 along the blast guide plate 20a inclined upward. The upper blower guide plate 20 penetrates into the barrel storage area 1a along the upper surface of the barrel storage area 1a, and the pin 22 guides the guide groove 2
5 occupies the vicinity of the entrance of the barrel storage area 1a. As a result, the air blown from the upper portion does not disturb the flow, and the barrel 10
Guided into.

On the contrary, when the barrel 10 is rotated upward as shown by the chain double-dashed line, the lower blower guide plate 20a.
Enter the barrel storage area 1a, and the upper air guide plate 20 is inclined downward. Thereby, the air blow in the upper part of the air blow case 1 is smoothly guided into the barrel 10 along the air guide plate 20, and the flow of the air in the lower part is not disturbed.

In the above-described embodiment, it is conceivable that the blower guide plate 20 and the barrel 10 are connected by pinning instead of the integral hinge portion.

[0013]

According to the present invention, the air flow is adjusted even if the lower wall or the upper wall faces the air blow by adjusting the wind direction of the barrel downward or upward by the simple additional structure in which the air blow guide plate follows the barrel. Is rectified and enters.
