JPS619325A - Vehicle air blow-out gllile - Google Patents

Abstract

PURPOSE:To prevent air from directly blowing upon a shunt-off door to make it possible to prevent the closing of the door and the generation of abnormal sound due to wind pressure, by providing, at the upstream end of a casing, a windshield rib for covering the free end of the door when the door is fully opened. CONSTITUTION:When a dial is manupulated, a shut-off door 8 is opened and closed by means of a linkage. Due to the provision of a wind shield rib 12 air is prevented from directly blowing upon the shut-off door 8 upon full-opening so that no load in the direction in which the door 8 is closed is exerted thereto, and therefore, if the amount and velocity, etc. of blowing air are above their effective levels, the door 8 is surely held in its opening condition so that it is never unexpectedly closed. Accordingly, there may be prevented the closing of the shut-door by wind pressure and the generation of abnormal sound from a sealing sponge.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application This invention relates to an air outlet grill for a vehicle. (Refer to Publication Service Bulletin No. 4 trt (8G-4)). / is a case, which is connected to the front case co and the rear case 3, and inside this front case co, a louver for adjusting the left and right wind direction and a louver for adjusting the vertical wind direction are provided.

In addition, by operating the dial g, the shut door t can be opened and closed via the link 7.The shut door ♂ has a sealing member 2 made of sponge material etc. for sealing when it is in the fully closed state. etc. are installed 0
10 is a duct which is bent downward and connected to the rear case 3 of the case/ through a gasket//f.

Problems to be Solved by the C0 Invention However, in such conventional air outlet grilles, the duct lO is bent in an 11-shaped manner, so that the wind blown out from the unit (not shown) is Since the wind W blows upward from the bottom, the wind W always hits the lower surface of the door t when the door l is fully open.

For this reason, there are problems in that when the air volume is large, the wind pressure overcomes the force holding the door t open and closes it, and the wind W hits the sealing member and generates abnormal noise.

The present invention was developed by focusing on these conventional problems, and its purpose is to prevent wind from directly hitting the door.

Means for Solving Problem d1 In order to achieve the above object, the present invention provides a shut door which is rotatably disposed in a case connected to a duct, and when the shut door is fully opened, the shut door is free to rotate. A wind-shielding rib covering the end is formed at the upstream end of the case.Embodiment FIG. 1 is a diagram showing an embodiment of the present invention.First, the configuration will be explained. Inside the front case 3 and the rear case 3, louvers for left and right adjustment and louvers for up and down wind direction adjustment are provided. The shut door ♂ is attached to the rear case 3 by the bin 13 and is linked
It is interlocked with a dial (not shown) via a dial (not shown).

Further, the rear case 3 is provided with a rib l for a windshield for the door ♂. This windbreak rib f2 is
When the IQ is fully opened, the height is set so that it covers the free end of the shut door ♂, and it is formed into a wedge shape so that the flow of the wind W is smooth.

Furthermore, the ribs 12 are formed over the entire width of the rear case 3 in the left and right directions.

Next, the action will be explained.

When the dial (not shown) is operated, the shut door r opens and closes via the link (not shown). In Figure 1, the fully closed state is shown by a solid line, and the fully open state is shown by a chain line. Since the door r has a wind-shielding rib 2, the door r is prevented from being directly exposed to the wind W.

Therefore, the load in the direction in which the shut door l closes is not applied to the door +5', and the air volume is less than 5'.

If the wind speed is at a practical level, it's a door! As explained above, according to the present invention, the case is provided with a rib for preventing wind, and the shutter door is provided with a rib that prevents wind from flowing directly to the shut door. Since it is configured so that it does not hit, the effect of eliminating problems such as the shut door closing due to wind pressure or abnormal noises being generated from the sealing sponge can be achieved.
