DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a register mounted on, for example, an instrument panel of an automobile.

[0002]

2. Description of the Related Art As a conventional register of this type, for example, a register having a configuration as shown in FIGS. 7 and 8 is known. In this conventional configuration, a plurality of front wind direction deflecting plates 32 extending in the lateral direction are rotatably supported inside a substantially cylindrical blow duct 31 capable of passing wind from the rear to the front. . A plurality of rear wind direction deflecting plates 33 extending in the vertical direction are rotatably supported in the center of the inside of the air duct 31 so as to be located behind the front wind direction deflecting plate 32. One shut damper 34 extending in the vertical direction is rotatably supported inside the rear of the air duct 31 so as to be located behind the rear wind direction deflection plate 33.

An operation knob 35 is slidably attached to the front wind direction deflecting plate 32 located at the middle part in the vertical direction, and its rear end is vertically movable relative to one rear wind direction deflecting plate 33. Are linked. When the operation knob 35 is operated to move in the up-down direction, the plurality of front wind direction deflecting plates 32 are rotated while being integrally connected, and are blown out from the front end opening 31 a of the air duct 31. The direction of the wind is changed up and down. When the operation knob 35 is operated to move in the left-right direction, the plurality of rear wind direction deflecting plates 33 are rotated in a state of being integrally connected, and the wind blown out from the front end opening 31 a of the air duct 31 is controlled. The direction is changed to the left and right.

An operation dial 3 is provided below the air duct 31.
6 is rotatably mounted so as to be exposed forward, and is connected to a shut damper 34 via a gear transmission mechanism 37. When the operation dial 36 is rotated in one direction or the other direction, the shut damper 34 is rotated to the open position or the closed position via the gear transmission mechanism 37. Thereby, the air passage in the air duct 31 is opened or closed.

[0005]

However, in this conventional register, a front wind direction deflecting plate 32 and a rear wind direction deflecting plate 3 are arranged inside an air duct 31 along the extending direction thereof.
3 and the shut damper 34 are provided side by side. For this reason, the length L1 of the ventilation duct 31 becomes large, and there is a problem that it is difficult to secure a predetermined space behind the register in a state where the register is mounted on an instrument panel or the like.

In particular, the width L2 of the shut damper 34 is
In order to close the air passage in the air duct 31, the air passage is set large so as to be substantially the same as the width L3 of the air passage, that is, the front end opening 31a. In addition, the width L3 of the front end opening 31a of the air duct 31 may be set to be large due to a design factor, and accordingly, the width L2 of the shut damper 34 is further increased. As described above, the fact that the shut damper 34 having the large lateral width L2 is rotatably accommodated in the air duct 31 has caused the length L1 of the air duct 31 to be large.

In order to cope with the above-described problems in the conventional configuration, for example, a register in which a plurality of front wind direction deflecting plates 32 provided in a blower duct 31 are improved so as to also serve as a shut damper has been used. Proposed.

Since the front wind direction deflecting plate 32 is always exposed from the front end opening 31a of the air duct 31, providing a seal structure between the front wind direction deflecting plate 32 and the air passage of the air duct 31 is not desirable in terms of appearance. Not preferred. For this reason, a seal structure cannot be provided, and a gap is formed between the front wind direction deflecting plate 32 and the air passage of the air duct 31 in a state where the front wind direction deflecting plate 32 is pivotally disposed at the closed position. As a result, there is a problem that the air passage cannot be completely closed.

The present invention has been made by paying attention to such problems existing in the prior art. An object of the present invention is to provide a register capable of shortening the length of an air duct and securing a predetermined space in the rear when mounted on an instrument panel or the like.

A further object of the present invention is to provide a seal structure between a wind direction deflecting plate serving also as a shut damper and a blower duct without deteriorating the appearance, thereby completely closing a blower passage in the blower duct.
